Description

Technical Field

[0001] The present invention relates to the technical field of fixtures, in particular to a fixture for detecting shaft parts. Background Art

[0002] Shaft parts are one of the typical parts often encountered in hardware accessories. They are mainly used to support transmission components, transmit torque and bear loads. According to the different structural forms of shaft parts, they can generally be divided into three categories: smooth shafts, stepped shafts and special-shaped shafts; or they can be divided into solid shafts, hollow shafts, etc.

[0003] A fixture is a device used to fix the workpiece in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a clamp. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture.

[0004] In order to improve the accuracy of shaft parts inspection, the surface of the parts is usually inspected in all directions. However, most of the current fixtures need to re-clamp the parts and adjust their positions to facilitate the inspection of other parts of the parts. The flexibility of the fixtures is poor, and it is difficult to adjust according to the size of the shaft parts within a certain range. The applicability is insufficient. Therefore, in response to the above shortcomings, the present invention makes the following improvements. Summary of the Invention

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1 and Figure 3As shown, the present invention provides a technical solution. Most fixtures need to re-clamp the parts and adjust their positions to facilitate the inspection of other parts of the parts. The flexibility of the fixture is poor. In order to improve the scope of application of the fixture, the specific improvements are as follows:

[0030] The fixture for detecting shaft parts includes a base 1, mounting seats 2 are slidably provided on both sides of the top of the base 1, and a clamping mechanism 3 is provided on the top of the mounting seats 2;

[0031] When the cam 31 is unlocked, the first and second motors 312 are unlocked, and the second motor 312 is unlocked, so that the cam 31 is unlocked. The inner wall of the sleeve 33 is fixedly provided with a protrusion, which is slidably arranged inside the slide groove. The top and bottom of the fixed plate 34 are both provided with a protrusion 35, and the inner part of the protrusion plate 35 is slidably provided with a clamping plate 36. The opposite side of the two clamping plates 36 is provided with a clamping block 37. The interior of the clamping plate 36 is threadedly connected to the surface of the clamping block 37 by a fastening bolt 4. After the surface of the clamping block 37 is worn, the clamping block 37 can be easily replaced. A sliding ring 38 is slidably provided on the other side of the surface of the movable sleeve 33, and the top and bottom surfaces of the sliding ring 38 are provided with a groove. An inclined rod 315 is rotatably provided inside the groove, and one end of the inclined rod 315 is rotatably connected to one side of the clamping plate 36. A first electric push rod 39 is fixedly provided on the top surface of one of the protrusion plates 35, and a connecting plate 310 is fixedly provided on the protruding end of the first electric push rod 39. The bottom of the connecting plate 310 is fixedly connected to one side of the top surface of the sliding ring 38.

[0032] The shaft part is placed between the two clamping blocks 32, and the second electric push rod 314 is started, so that the protruding end of the second electric push rod 314 drives the movable sleeve 33 to move toward the part through the Y-shaped limit plate 313, so that the two clamping blocks 37 are respectively located on the top and bottom surfaces of the end of the part, and the first electric push rod 39 is started, so that the protruding end of the first electric push rod 39 drives the sliding ring 38 to move along the surface of the movable sleeve 33 through the connecting plate 310, so that the sliding ring 38 moves in the direction away from the fixed plate 34. At this time, due to the rotation setting of the two ends of the inclined rod 315, the clamping plate 36 can move inside the convex plate 35, and the two clamping plates 36 drive the clamping blocks 37 to approach the part until The clamping surface of the clamping block 37 contacts the surface of the part until it is clamped and fixed. When the detection position of the part needs to be adjusted, the first motor 312 is started, so that the first motor 312 drives the rotating rod 31 to rotate, and the movable sleeve 33 rotates synchronously through the setting of the protrusion and the slide groove. The clamping of the part by the clamping block 37 can drive the part to rotate synchronously, and the detection position can be adjusted. Similarly, when no clamping is required, the sliding ring 38 is controlled to move along the movable sleeve 33 toward the fixed plate 34. At this time, the two clamping plates 36 drive the clamping block 37 away from the part, thereby releasing the clamping of the part, and then the second electric push rod 314 is controlled to drive the movable sleeve 33 away from the part through the Y-shaped limit plate 313.

[0033] Example 2

[0034] Based on Example 1, please refer to Figure 1 and Figure 4 As shown, in order to facilitate the adjustment of the fixture according to the length of the shaft parts, the specific improvements are as follows:

[0035] A driving member 5 is provided on the top surface of the base 1, and the driving member 5 is used to drive the mounting seat 2 to move. The driving member 5 includes a second motor 51 fixedly provided on the top surface of the base 1, and one end of the output shaft of the second motor 51 is fixedly connected to the first gear 52 through a coupling. The interiors of the two mounting seats 2 are both threadedly connected with threaded rods 53, and the thread directions of the surfaces of the two threaded rods 53 are opposite. A connecting rod 54 is fixedly provided between the opposite ends of the two threaded rods 53, and a second gear 55 is fixedly provided on the surface of the connecting rod 54. A guide rod 56 is fixedly provided between the two sides of the top of the base 1 through a short plate, and the mounting seat 2 is slidably provided on the surface of the guide rod 56.

[0036] Start the second motor 51, so that the second motor 51 drives the connecting rod 54 to rotate through the first gear 52 and the second gear 55, and then the threaded rod 53 rotates synchronously. Since the thread directions of the two threaded rods 53 are opposite, the two mounting seats 2 can move relative to or away from each other along the surface of the guide rod 56, and the two clamping mechanisms 3 move relative to or away from each other synchronously, so that they can be adaptively adjusted within a certain range according to the length of the shaft parts.

[0037] Example 3

[0038] Based on Example 2, please refer to Figure 2 As shown, in order to provide stable support for shaft parts during clamping, the specific improvements are as follows:

[0039] A supporting mechanism 6 is provided on the top surface of the base 1, and the supporting mechanism 6 includes a hydraulic cylinder 61 fixedly provided on the top surface of the base 1, an arc-shaped supporting plate 62 is fixedly provided at the protruding end of the hydraulic cylinder 61, and a roller 63 is provided at the bottom of the inner wall of the arc-shaped supporting plate 62 for rotation through a fixed axis, and the setting of the roller 63 does not affect the rotation of shaft parts.

[0040] The shaft parts are placed on the roller 63 inside the arc-shaped support plate 62, which, in conjunction with the setting of the hydraulic cylinder 61, can provide stable support without hindering the rotation requirements of the shaft parts during testing.
