Fig. 1 is a schematic structural diagram of a sphere part coating fixture provided in an embodiment of the present application, fig. 2 is an exploded structural diagram of the sphere part coating fixture provided in the embodiment of the present application, and fig. 3 is a cross-sectional view of the sphere part coating fixture provided in the embodiment of the present application.
Referring to fig. 1, 2 and 3, the coating fixture 100 for a spherical component of the present embodiment includes a receiving tray 10, an adjusting member 20 disposed on the receiving tray 10, and a positioning sleeve 30 disposed on the adjusting member 20.
The accommodating disc 10 includes a base 11 having a supporting surface 13 and an annular rib 12 disposed on the base 11, wherein the supporting surface 13 and the annular rib 12 define an accommodating cavity 14 for accommodating the ball element 50. The positioning sleeve 30 has a positioning surface 31 disposed opposite to the inner side surface of the annular rib 12, the positioning surface 31 is configured as a conical surface, and the small-diameter end of the positioning surface 31 is disposed near the support surface 13. The adjusting element 20 is used to move the positioning sleeve 30 toward the supporting surface 13, so as to press the ball element 50 in the receiving cavity 14, i.e. on the supporting surface 13 and the annular rib 12, by means of the positioning surface 31.
In the above solution, the accommodating disc 10 includes the base 11 and the annular rib 12, which can together enclose the accommodating cavity 14, and the ball part 50 can be easily placed in the accommodating cavity 14 and is blocked by the annular rib 12 and is not easily rolled out of the accommodating cavity 14, which can achieve the pre-positioning of the ball part 50 at the initial stage of installation. In addition, the conical positioning surface 31 on the positioning sleeve 30 is arranged opposite to the annular rib 12, and when the adjusting piece 20 is operated to drive the positioning sleeve 30 to move towards the supporting surface 13, the distance between the area, which is over against the inner side surface of the annular rib 12, on the positioning surface 31 and the annular rib 12 is continuously reduced until the spherical part 50 is clamped between the positioning surface 31 and the annular rib 12. During installation, the ball element 50 is placed in the accommodating cavity 14, and the distance between the positioning sleeve 30 and the supporting surface 13 in the depth direction S of the accommodating cavity 14 is adjusted to complete installation. Compared with the prior art that the relative positions of the spherical part 50 and the columnar clamp must be guaranteed, the installation is simpler, and the clamping efficiency is higher. And because the positioning surface 31 is a conical surface, the tolerance requirement of the whole clamp is reduced, and the manufacturing cost of the clamp is reduced.
In addition, the supporting surface 13 of the base 11, the annular rib 12 and the positioning sleeve 30 position the ball element 50 at the bottom and two opposite sides of the ball element 50, so that the contact area with the ball element 50 is small, and the clamping in three directions is reliable.
As shown in fig. 3, an annular rib 12 may surround the outer edge of the base 11, wherein the top end surface of the base 11 may be formed as a support surface 13, so that the support surface 13 and the inner side surface of the rib 12 radially inside together define a receiving cavity 14. The receiving space can be, for example, a hood-shaped space. When the base 11 may have other shapes, the annular rib 12 may be formed at other positions of the base 11 as long as the annular rib and the supporting surface 13 can define the accommodating cavity 14.
It should be noted that, the rib 12 is annular, specifically, the end of the rib 12 is closed, so as to form the accommodating cavity 14 together with the supporting surface 13. For example, the annular rib 12 may refer to that the rib 12 is annular, and correspondingly, the base 11 may be formed in a circular truncated cone shape, so that the annular rib 12 surrounds the entire circumference of the outer edge of the base 11. Of course, the shape of the rib 12 is not limited to a circular ring shape, and may be a polygonal shape or a ring shape surrounded by other shapes.
In the embodiment of the present application, in order to form an effective clamping of the ball element 50 between the rib 12 and the positioning surface 31 of the positioning sleeve 30, the height of the rib 12 relative to the supporting surface 13 may be higher than the radius of the ball element 50.
In addition, as previously described, the ball element 50 is supported on the support surface 13 and clamped between the locating surface 31 and the inner side of the rib 12. In order to facilitate the movement of the ball element 50 to the position of the rib 12, it is conceivable to arrange the support surface 13 to be inclined.
Specifically, the supporting surface 13 may include an annular guide area 131, the guide area 131 is located radially inside the rib 12 and is adjacent to the rib 12, and the setting height of the guide area 131 with respect to the bottom end surface 111 of the base is gradually reduced from the inside of the guide area 131 to the outside. The term "the guiding region 131 is adjacent to the rib 12" means that the outer edge of the guiding region 131 is continuous with the inner side of the rib 12, or the outer edge of the guiding region 131 is close to the inner side of the rib 12 and is spaced from the inner side of the rib 12 by a short distance, which is smaller than the diameter of the ball 50.
For example, the guiding region 131 may be configured as a conical surface, with the small diameter end of the guiding region 131 facing the center of the base 11 and the large diameter end of the guiding region 131 facing the rib 12. Thus, when the ball element 50 is placed in the accommodating cavity 14, the ball element can roll to contact with the rib 12 under the action of gravity, so that the automatic pre-positioning of the ball element 50 can be completed, and the positioning process is simple and easy to implement.
It should be noted that the extension of the guiding area 131 in the radial direction of the base can be set according to the size of the actual ball element 50, and can occupy only a partial range of the supporting surface 13 as shown in fig. 3, or can extend to the whole supporting surface 13, as long as it can achieve the purpose of automatically rolling the ball element 50 entering the receiving cavity 14 onto the rib 12.
In order to further improve the clamping efficiency, a plurality of ball parts 50 can be placed in the receiving cavity 14 at one time during the mounting, and since the radius of the ball parts 50 placed at the same time is generally the same, it is also necessary to make the central axis of the positioning surface 31 coincide with the central axis of the flange 12. This ensures that the spacing between the locating surface 31 of the locating sleeve 30 and the inner side of the collar 12 is the same over the entire circumference of the collar 12.
Referring to fig. 2 and 3, in the embodiment of the present application, as described above, in order to clamp the ball component 50 in cooperation with the rib 12, the positioning sleeve 30 has the positioning surface 31 disposed opposite to the inner side surface of the rib 12, the positioning surface 31 is configured as a conical surface, and the small diameter end of the conical surface is disposed near the supporting surface 13. In other words, the positioning surface 31 is a conical surface with a small diameter end facing the supporting surface 13, so that when the adjusting member 20 drives the positioning sleeve 30 to move toward the supporting surface 13, the distance between the region of the positioning surface 31 opposite to the inner side surface of the rib 12 and the inner side surface of the rib 12 becomes smaller and smaller to form a space for holding the ball element 50.
It can be understood that the size of the positioning surface 31 in the depth direction S of the accommodating cavity 14 can be set according to actual needs, so as not to affect the coating of the spherical part 50.
In the embodiment of the present application, referring to fig. 2 and 3, in a possible implementation, the adjusting member 20 may include an adjusting rod 21 and a pressing member 22, the adjusting rod 21 is disposed on the base 11 and is movable in the depth direction S of the accommodating cavity 14 relative to the base 11, and the movement may include that the adjusting rod 21 is movable in both directions of the depth direction.
Illustratively, the adjusting rod 21 may be threadedly coupled to the base 11, such that the relative position of the rod 21 and the base 11 can be adjusted by turning the adjusting rod 21 clockwise or counterclockwise. Of course, in order to facilitate the connection between the ball part coating clamp 100 and other components, the adjusting rod 21 may be disposed through the base 11, so that the portion of the adjusting rod 21 penetrating through the base 11 may be used to connect with external components.
The compression member 22 may be disposed on the adjustment rod 21 and opposite the support surface 13, and the positioning sleeve 30 is disposed on the adjustment rod 21 and between the compression member 22 and the support surface 13. When the adjusting lever 21 carries the pressing member 22 to move toward the supporting surface 13, the pressing member 22 presses the positioning sleeve 30 to approach the supporting surface 13, and in the process, the positioning surface 31 also moves along with the positioning sleeve 30 toward the supporting surface 13.
In a specific implementation, the adjusting rod 21 may be provided with a flange portion 221, the flange portion 221 may protrude radially outward from the adjusting rod 21, and the crimping member 22 may be sleeved on the adjusting rod 21 and located between the flange portion 221 and the positioning sleeve 30. Among them, the flange part 221 may be formed at an end of the adjusting lever 21. Specifically, when the adjusting lever 21 is moved toward the support surface 13 during clamping, the flange portion 221 can move toward the support surface 13 together with the pressure contact member 22.
In the embodiment of the present application, the adjusting member 20 may further include an elastic member 222, the elastic member 222 is disposed on the adjusting lever 21, the elastic member 222 is located between the flange portion 221 and the pressing member 22, and the elastic member 222 is used for applying an elastic force to the pressing member 22 toward the supporting surface 13 to press the pressing member 22 against the positioning sleeve 30.
During installation, the adjusting rod 21 drives the flange portion 221 to move toward the supporting surface 13, the flange portion 221 presses the elastic member 222 to apply an elastic force to the pressing member 22, and the pressing member 22 is pressed against the positioning sleeve 30.
By the arrangement, on one hand, the situation that the clamping force is loosened or expanded and extruded due to high-temperature deformation is avoided, and the falling or deformation damage of the ball part 50 is avoided. On the other hand, the ball element 50 can be quickly assembled and disassembled by compressing the elastic member 222, so that the assembly efficiency is improved.
For example, the elastic member 222 may be a spring or an elastic washer, and the elastic member 222 may be made of a material resistant to high temperature.
In addition, the adjusting rod 21 can drive the flange 221 to move in the direction away from the supporting surface 13, and at this time, the elastic force applied by the pressing member 22 to the positioning sleeve 30 through the elastic member 222 disappears or decreases, so that the operator can lift the positioning sleeve 30 and make the ball element 50 separate from the accommodating disc 10.
Note that both end portions of the elastic member 222 may be connected to the flange portion 221 and the crimp member 22, respectively, or both end portions of the elastic member 222 may be unconnected to both the flange portion 221 and the crimp member 22. Here, the adjustment lever 21 and the flange portion 221 may be integrally formed, and may be, for example, a bolt.
With continued reference to fig. 2, the positioning sleeve 30 may include a main body portion 32 and a protrusion portion 33, the main body portion 32 is disposed on the adjusting rod 21, the protrusion portion 33 is disposed on the main body portion 32 and protrudes from the main body portion 32 toward the rib 12, and the surface of the protrusion portion 33 facing the annular rib 12 forms a positioning surface 31. It will be appreciated that the positioning surface 31 is provided on the projection 33 to minimize the weight of the positioning sleeve 30. In addition, the main body portion 32 and the protrusion portion 33 may be formed integrally or separately.
With continued reference to fig. 3, further, in order to facilitate guiding the movement of the positioning sleeve 30, the base 11 further includes a guide sleeve 15 protruding from the supporting surface 13, the guide sleeve 15 can be inserted into the positioning sleeve 30, and the inner surface of the guide sleeve 15 is inserted by the adjusting rod 21, the guide sleeve 15 is located between the positioning sleeve 30 and the adjusting rod 21 to guide the movement of the guide sleeve 15 towards the supporting surface 13. The guide sleeve 15 and the positioning sleeve 30, and the guide sleeve 15 and the adjusting rod 21 can be in clearance fit, so that the guide sleeve 15 can move relative to the adjusting rod 21. In addition, the base 11 may be threadably coupled to the adjustment rod 21, which facilitates movement of the adjustment rod 21 relative to the base 11. The inner surface of the guide sleeve 15 may be provided with internal threads that mate with the adjustment rod 21 to facilitate threading of the adjustment rod 21.
In the embodiment of the present application, as described above, the positioning sleeve 30 is disposed on the receiving tray 10 through the adjusting member 20. The adjusting member 20 is used to move the positioning sleeve 30 toward the supporting surface 13, so that the positioning surface 31 presses the ball element 50 against the supporting surface 13 and the rib 12. Further, the adjusting member 20 can be used to move away from the supporting surface 13 to release the positioning surface 31 from pressing the ball element 50, so as to facilitate the detachment of the ball element. Fig. 4 is a schematic structural diagram of a ball part coating fixture in a use state according to an embodiment of the present application. Next, the clamping step of the sphere member plating jig 100 of the present embodiment will be described with reference to fig. 1, fig. 3, and fig. 4.
The receiving disc 10 is placed substantially horizontally and a plurality of, for example 9, ball elements 50 are placed into the receiving cavity 14 of the receiving disc 10. In this way, the ball element 50 rolls under the guidance of the guide region 131 against the inner side of the rib 12.
The positioning sleeve 30 is sleeved outside the guide sleeve 15, and the guide sleeve 15 is pressed downwards (towards the supporting surface 13) to complete the initial installation of the ball part 50.
The adjusting rod 21 of the adjusting member 20 is screwed into the guiding sleeve 15 and penetrates through the base 11, and in the process, as the adjusting rod 21 is screwed in, the flange part 221 presses the pressing member 22 and the positioning sleeve 30 through the elastic member 222 until the positioning surface 31 on the positioning sleeve 30 presses the ball element 50 against the inner side surface of the rib 12 and the supporting surface 13, as shown in the state of fig. 4.
At this time, the contact of the support surface 13, the inner side surface of the rib 12, and the positioning surface 31 of the positioning sleeve 30 with the ball element 50 is point contact, which can make the ball element 50 have a large exposed area, thereby increasing the effective deposition area of the ball element 50.
The process of removing the ball element 50 is reversed. Specifically, the adjusting rod 21 of the adjusting member 20 is moved away from the supporting surface 13, i.e., the adjusting rod 21 is unscrewed from the guide sleeve 15. In the process, as the adjusting rod 21 is continuously screwed out, the flange part 221 is gradually far away from the press-connection part 22, the elastic force of the elastic part 222 to the press-connection part 22 is reduced or eliminated, and at this time, the positioning sleeve 30 is manually lifted, or the part coating clamp 100 is turned upside down, so that all, for example, 9 ball parts 50 in the accommodating disc 10 can be quickly removed in batch, and the assembling and disassembling efficiency is also improved.
It can be understood that, since the positioning surface 31 on the positioning sleeve 30 is configured as a conical surface in the present embodiment, for spherical parts 50 with different sizes, the distance between the positioning sleeve 30 and the supporting surface 13 and the height dimension of the rib 12 can be adjusted.
Fig. 5 is a schematic view of another application scenario of the sphere part coating fixture provided in the embodiment of the present application. Referring to fig. 5, in some cases, for example, for clamping a ball part 50 with a smaller diameter, the clamping can be realized by appropriately reducing the height of the rib 12 and appropriately increasing the protruding length of the protruding portion 33, i.e., the radial dimension of the protruding portion 33, on the basis of the part coating jig shown in fig. 3, so that the distance between the positioning surface 31 and the inner side surface of the rib 12 is reduced, and the clamping is suitable for the ball part 50 with a small size.
Similarly, for example, for clamping a ball part 50 with a larger diameter, the clamping can be realized by appropriately increasing the height of the rib 12 and appropriately decreasing the protruding length of the protruding portion 33 on the basis of the part coating jig shown in fig. 3, so that the distance between the positioning surface 31 and the inner side surface of the rib 12 is larger, and the clamping is suitable for a ball part 50 with a larger size.
It can be understood that the number of the ball parts 50 that can be clamped in the annular region formed by the supporting surface 13, the inner side surface of the rib 12 and the positioning surface 31 can be set according to requirements, and adjacent ball parts 50 can contact with each other or have a certain interval.
Fig. 6 is a front view of the sphere part coating clamping mechanism provided in the embodiment of the present application, and fig. 7 is a schematic overall structure diagram of the sphere part coating clamping mechanism provided in the embodiment of the present application.
Referring to fig. 6 and 7, the embodiment of the present application further provides a sphere part coating clamping mechanism 200, which includes a mounting seat 201 and a plurality of the sphere part coating clamps 100, and it should be noted that the structure, principle, function, and the like of the sphere part coating clamp 100 have been described in detail above, and are not described again here.
Specifically, the mounting base 201 has a mounting surface 202, a plurality of ball part coating jigs 100 are arranged at intervals on the mounting surface 202, and the adjusting member 20 in the ball part coating jig 100 penetrates the base 11 and is connected to the mounting surface 202. Wherein the support surface 13 is located at a side facing away from the mounting surface 202.
Illustratively, the mounting base 201 may be a rectangular parallelepiped, and has four planar mounting surfaces 202, and each mounting surface 202 may be provided with a plurality of ball part coating fixtures 100. Of course, each ball component plating jig 100 is arranged in such a manner that the adjustment rod 21 is perpendicular to the mounting surface 202. The outer contour of the mounting seat 201 may be a regular polyhedron, and the number and arrangement of the ball part coating jigs 100 on the mounting surface 202 may be set as needed, so that the ball part coating jigs 100 on the mounting surfaces 202 do not interfere with each other. Because a plurality of spherical parts 50 can be clamped on one spherical part coating clamp 100, and a plurality of groups of spherical part coating clamps 100 can be arranged on one mounting seat 201, the spherical part coating clamping mechanism of the invention has the advantages of more spherical parts 50, higher mounting density and higher single coating yield, and is beneficial to reducing the process cost of a single part.
It should be noted that each ball part coating jig 100 should be mounted on the mounting surface 202 after the ball part 50 thereon is mounted.
In addition, in order to facilitate the coating process to be more uniform, a rotating shaft 203 may be further disposed on the mounting base 201, an axis of the rotating shaft 203 is parallel to the mounting surface 202, and the rotating shaft 203 is used for driving the mounting base 201 to rotate under the driving of an external rotation source.
All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
