Detailed Description

In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following description will refer to the accompanying drawings to describe specific embodiments of the present invention. It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be obtained from these drawings without inventive effort. The designation of the design orientation merely indicates the relative positional relationship between the respective members, not the absolute positional relationship.

Example 1

Referring to fig. 1 to 5, a clamping device for positioning an end cap includes a base 1, a positioning device 2 disposed on the base 1 for positioning a pin hole of the end cap, and a supporting member 3 for supporting the bottom of the end cap, wherein the supporting member 3 is disposed above the base 1.

In the prior art, the end cover is often directly pressed through the air cylinder to be fixed, so that a positioning plate which is matched with the end cover needs to be arranged, and when the end covers of different specifications are switched, the positioning plate needs to be replaced, and the operation is very troublesome. Therefore, this embodiment passes through positioner 2 fixes a position the hitching leg hole of end cover, then passes through support piece 3 supports the butt to the bottom of end cover, adopts the mode of hitching leg hole location plus an angle location to fix the end cover, and the location is accurate, device simple structure, convenient to use.

As shown in fig. 1, the positioning device 2 includes a supporting plate 201 vertically disposed on the base 1, an air cylinder 202 disposed on a side wall of the supporting plate 201, a pressing rod 203 fixedly connected to a power output end of the air cylinder 202, and a positioning pin 204 disposed on one side of the pressing rod 203 facing the supporting plate 201 and used for positioning a pin hole of the end cover, wherein the power output end of the air cylinder 202 is perpendicular to the supporting plate 201.

In the embodiment, as shown in fig. 2, the cylinder 202 can push the pressing rod 203 to move up and down, so as to drive the positioning pin 204 to move up and down. The pin hanging holes of the end cover are sleeved on the positioning pin 204, then the air cylinder 202 moves downwards, so that the positioning pin 204 compresses and fixes the end cover, and the positioning pin 204 is abutted with the pin seat on the supporting plate 201, so that the pin hanging holes of the end cover are clamped and positioned. After the pneumatic marking is finished, the air cylinder 202 moves upwards, so that the positioning pin 204 is separated from the end cover hanging pin hole, and the end cover can be taken down. The positioning is accurate, and the operation is very simple.

The positioning pin 204 is detachably connected with the pressure lever 203. When the end covers of different specifications need to be marked, the positioning pin 204 can be directly detached and replaced, and the operation process is simple and the cost is low.

Example 2

In order to position the end caps with different specifications, the position of the positioning pin 204, that is, the position of the pressing rod 203, needs to be moved. In order to maintain the stable connection between the positioning pin 204 and the pressing rod 203, in this embodiment, on the basis of embodiment 1, the supporting plate 201 includes a limiting plate 2011 vertically disposed on the base 1, a first sliding slot 2012 disposed on the limiting plate 2011, a sliding block 2013 slidably disposed in the first sliding slot 2012, and a sliding plate 2014 fixedly connected to the sliding block 2013, and the cylinder 202 is disposed on a side wall of the sliding plate 2014.

By means of the arrangement, when the sliding block 2013 is slid, the sliding plate 2014 can slide together, so that the cylinder 202 and the positioning pin 204 are driven to slide together, the positioning pin 204 and the pressing rod 203 can slide together, and the end covers of different specifications can be adjusted to appropriate positions at any time, so that locking and positioning are facilitated. In the sliding process, the relative position of the pressure lever 203 and the positioning pin 204 cannot be changed, so that the pressing stability of the pressure lever 203 is high, the pressing force cannot be weakened due to sliding, and the positioning accuracy and the positioning effect are good.

The limiting plate 2011 is fixedly connected with the base 1 through an M8 screw. The limiting plate 2011 mainly functions as a rail to ensure that the slider 2014 can slide stably on the limiting plate 2011.

Example 3

After the hitching leg hole to the end cover is fixed a position, the end cover still needs to be supported by propping from another angle to play the role of fixing the end cover. The supporting piece 3 can support the end cover from the bottom of the end cover, and can prevent the end cover from rotating around the hitching leg hole.

In order to ensure the stability of the supporting member 3, on the basis of embodiment 2, as shown in fig. 4, in this embodiment, the supporting member 3 includes a fixing plate 301 horizontally disposed on the base 1, and a top plate 302 connected to the fixing plate 301. The top of the top plate 302 is abutted against the bottom of the end cover, an upward oblique force is exerted on the end cover, and the stable clamping of the end cover can be kept after the end cover is matched with the foot hanging hole for positioning.

In order to enhance the supporting stability of the end cover by the supporting member 3, the top of the top plate 302 is provided with a hanging corner for abutting against the side wall of the end cover. The interference area between the top plate 302 and the end cap can be increased, thereby improving the interference stability.

However, when replacing end caps with different specifications, the position of the top plate 302 may need to be moved, so in this embodiment, the fixing plate 301 is provided with a second sliding groove 303, a bolt 305 is slidably provided in the second sliding groove 303, the base 1 is provided with a through hole 304 connected to the second sliding groove 303, and the fixing plate 301 and the base 1 are fixed by the bolt 305 passing through the second sliding groove 303 in a clamping manner.

By such arrangement, the fixing plate 301 can be moved by loosening the bolt 305, and the bolt 305 is locked when the fixing plate 301 is moved to a proper position, so that the position of the fixing plate 301 can be fixed.

Therefore, the clamping device is used in end cover location that this embodiment provided adopts the cylinder to press from both sides tight mode, and cooperation support piece comes conflict chucking end cover from another angle, and not only the commonality is high, and the preparation time of changing different specification end covers is short moreover, adopts the air compression stable safe and reliable nature strong of operation, has improved production efficiency and product quality, reduction personnel intensity of labour.
