Referring to fig. 1, 2 and 3, the inspection apparatus 100 includes a base 10, an inspection piece 20, a measuring head 30 and a supporting assembly 40.
In the present embodiment, the base 10 functions to support the detecting member 20, and the base 10 includes a base plate 11, a support rod 12, a mount 13, and a locking member 14. The supporting rod 12 is a cylindrical rod, one end of the supporting rod 12 is connected to the bottom plate 11, and the supporting rod 12 is perpendicular to the bottom plate 11. The mount pad 13 is the cubic structure, and mount pad 13 is used for fixed detection piece 20, has seted up logical groove 131 on the mount pad 13, and bracing piece 12 wears to locate in logical groove 131, and mount pad 13 can follow bracing piece 12 and slide to adjust the height of detection piece 20. The mounting seat 13 is convexly provided with two locking parts 132 which are arranged at intervals, and the locking parts 132 are positioned at two sides of the through groove 131. In this embodiment, the locking member 14 may be a bolt, and the locking member 14 penetrates one of the locking portions 132 and is screwed to the other locking portion 132.
The mounting base 13 is also provided with a mounting groove 133 and two protrusions 134. The mounting groove 133 is spaced from the through groove 131, the mounting groove 133 is used for mounting the detecting member 20, and the two protruding portions 134 are spaced from each other and located at two sides of the mounting seat 13. The detection device 100 further includes a holder 50, for example, the holder 50 may be a bolt, and the holder 50 passes through one of the protrusions 134 and is screwed onto the other protrusion 134. When the detecting piece 20 is placed in the mounting groove 133, the two protruding portions 134 are close to each other by screwing the fixing pieces 50, and at this time, the two fixing pieces 50 drive the groove walls of the mounting groove 133 to clamp the detecting piece 20, so as to achieve the purpose of fixing the detecting piece 20. Since the operator can clamp the detecting member 20 or unclamp the detecting member 20 by rotating the holding member 50, the operation is simple and easy.
The detecting member 20 is provided with a movable rod 21 which can be extended and contracted, and when the movable rod 21 is compressed, the detecting member 20 displays a reading, thereby realizing the purpose of measurement. In this embodiment, the detecting member 20 may be an electronic height gauge, which may be used to directly measure the minor diameter of the thread. When the detected workpiece 200 is replaced with a workpiece 200 having a large diameter from a workpiece 200 having a small diameter, the movable rod 21 can be adapted to detect a workpiece 200 having a different diameter because the movable rod 21 can be moved in a telescopic manner.
The measuring head 30 is connected to the movable rod 21, the measuring head 30 is provided with a measuring part 31 in a protruding manner, and the thickness of the measuring part 31 gradually decreases from one end close to the detecting member 20 to one end close to the supporting component 40, so that the measuring part 31 can easily extend into the root of the thread to detect the minor diameter of the thread. During the process of measuring the screw thread, the measuring head 30 drives the movable rod 21 to move, so that the detecting piece 20 displays the reading to achieve the purpose of measurement. Since the measurement result can be obtained only by abutting the measuring head 30 against the workpiece 200, the detection efficiency of the detection device 100 is improved.
Before the workpiece 200 is inspected, the inspection piece 20 needs to be adjusted to the zeroing position, an operator can manually unscrew the locking piece 14, then slide the mounting seat 13 to lower the height of the inspection piece 20 so as to make the mounting seat 13 at a proper height, thereby making the measuring head 30 connected to the inspection piece 20 abut against the supporting component 40, and finally screw the locking piece 14, so that the zeroing adjustment is completed.
When detecting the minor diameter of the thread, the workpiece 200 is placed on the support assembly 40, and then the measuring head 30 is abutted against the workpiece 200, wherein the measuring head 30 and the support assembly 40 are abutted against the root of the thread along the radial direction of the workpiece 200. When the measuring head 30 abuts against the root of the thread, the movable rod 21 is compressed so that the detecting member 20 displays a reading to measure the minor diameter of the thread.
In order to facilitate the placement of the workpiece 200 between the support assembly 40 and the measuring head 30 during the screw thread detection, the detection device 100 further includes a lifting frame 60, one end of the lifting frame 60 is connected to the movable rod 21, when the workpiece 200 is placed, an operator can lift the lifting frame 60, so that the lifting frame 60 drives the movable rod 21 to move, and the movable rod 21 drives the measuring head 30 to be far away from the support assembly 40, so that the workpiece 200 can be placed on the support assembly 40.
The support assembly 40 includes a support 41 and a movable member 42. The supporting member 41 is disposed on one side of the base 10, in this embodiment, the supporting member 41 is disposed below the measuring head 30, the movable member 42 is disposed on the supporting member 41, the supporting member 41 is provided with a supporting portion 411 in a protruding manner, the movable member 42 is provided with an abutting portion 421 in a protruding manner, the supporting portion 411 and the abutting portion 421 are both used for abutting against the root of the thread, and the thicknesses of the supporting portion 411 and the abutting portion 421 are both gradually increased from one end close to the detecting member 20 to one end far from the detecting member 20. By this arrangement, the supporting portion 411 and the abutting portion 421 can be made to extend between the two thread teeth and abut against the root of the thread. The supporting portion 411 and the abutting portion 421 are used to jointly abut against the root of the thread to play a role in supporting the workpiece 200.
When the minor diameter of the thread needs to be detected, the workpiece 200 is placed on the supporting member 41 and the movable member 42, and then the measuring head 30 is abutted against the root of the thread, and it should be noted that the supporting member 41 and the measuring head 30 are respectively located at two sides of the workpiece 200 along the radial direction of the workpiece 200, and the movable member 42 and the detecting member 20 are located at the same side of the workpiece 200. When the measuring head 30 abuts against the root of the thread, the measuring result of the detecting member 20 is the minor diameter dimension of the thread. After the workpiece 200 is inspected, the workpiece 200 is removed from the supporting assembly 40, and the measuring head 30 is restored to the initial position, i.e. the measuring head 30 abuts against the supporting member 41 and the movable member 42, and the reading on the inspection member 20 is also zeroed.
The supporting member 41 is provided with a chute 412, the movable member 42 is slidably mounted in the chute 412, and the distance between the supporting portion 411 and the abutting portion 421 can be adjusted by adjusting the position of the movable member 42 in the chute 412. Because the workpieces 200 are various in types and different in screw pitches of the workpieces 200 with different specifications, when detecting the screw thread of the workpiece 200, an operator can slide the movable piece 42 according to the screw pitch on the screw thread, so that the purpose of adjusting the distance between the supporting part 411 and the abutting part 421 is achieved. The chute 412 serves as a guide for the movable member 42 during sliding of the movable member 42.
Referring to fig. 1 and 4, to fix the movable member 42, the detecting device 100 further includes a magnetic attraction member 70, for example, the magnetic attraction member 70 may be a magnet. The movable member 42 is provided with a containing groove 422, the containing groove 422 is located at one side of the movable member 42 facing the supporting member 41, and the magnetic attraction member 70 is installed in the containing groove 422, wherein the magnetic attraction member 70 can be installed in the containing groove 422 through interference fit, and can also be installed in the containing groove 422 through glue adhesion. When the movable member 42 is placed in the chute 412, the magnetic attraction member 70 generates a magnetic attraction force on the supporting member 41, and at this time, the movable member 42 is fixed on the supporting member 41 under the action of the magnetic attraction member 70, and it should be noted that the movable member 42 cannot easily slide relative to the supporting member 41 without external force interference. When it is necessary to adjust the distance between the supporting portion 411 and the abutting portion 421, an operator can apply an external force to the movable member 42 by a human hand to move the position of the movable member 42.
Referring to fig. 5, in another embodiment, a waist-shaped hole 423 is formed on the movable member 42, and the extending direction of the waist-shaped hole 423 is the same as the extending direction of the chute 412. The detection device 100 further comprises a fixing member 80, for example, the fixing member 80 may be a bolt. The fixing member 80 passes through the waist-shaped hole 423 and is screw-coupled to the supporting member 41. When the position of the movable member 42 is adjusted, the adjustment can be completed by unscrewing the fixed member 80, sliding the movable member 42, and finally screwing the fixed member 80 again.
The working process of the detection device 100 provided in the embodiment of the present utility model is approximately as follows:
firstly, the lifting frame 60 is lifted manually or by a mechanical arm, so that the lifting frame 60 drives the movable rod 21 to move, the movable rod 21 drives the measuring head 30 to be far away from the supporting component 40, then the workpiece 200 is placed on the supporting component 40, at the moment, the supporting part 411 on the supporting component 41 and the abutting part 421 on the movable component 42 abut against the root of the thread, then the lifting frame 60 is released, so that the measuring head 30 abuts against the workpiece 200, and at the moment, the reading is displayed on the detecting component 20 to measure the minor diameter of the thread. When measuring threads of different gauges, an operator may slide the movable member 42 according to the pitch of the threads to adjust the spacing between the supporting portion 411 and the abutting portion 421, thereby enabling the supporting assembly 40 to support the workpiece 200. Since the movable rod 21 of the detecting member 20 can be extended and contracted, the detecting member 20 can measure the workpieces 200 with different diameters, thereby improving the versatility of the detecting device 100. In addition, since the position of the movable member 42 can be adjusted, the support assembly 40 can be used to support the workpieces 200 having different pitches, thereby further improving the versatility of the inspection apparatus 100, and enabling the inspection apparatus 100 to inspect workpieces 200 having different thread specifications.
