DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A track shoe inspection fixture comprises a platform 1, wherein a tooth groove test block 1 2 and a tooth groove test block 21 are respectively installed on both sides of the upper part of the platform 1, and a plurality of limit grooves 7 are opened between the two. A support arm 6 is rotatably installed on one side of the inner side of the limit groove 7, and one end of the support arm 6 is connected to a rotating seat 14 through a connecting rod 15. One end of the rotating seat 14 is limitedly slidably installed on a connecting box 2 8 through a screw pair 13, and one side of the connecting box 2 8 is drivingly connected to a worm 10 through a connecting box 1 5;

[0024] Furthermore, a connecting box 5 is installed on one side of the bottom of the platform 1, and a driving head 9 is installed on one side of the connecting box 5. One end of the driving head 9 is fixedly connected to a worm 10, one end of the worm 10 penetrates into the connecting box 2 8, and meshes with the tooth grooves of the worm wheel 12 in the connecting box 2 8 for transmission, a screw rod 11 is fixedly installed in the middle of the worm wheel 12, and a screw rod pair 13 is installed at the upper limit position of the screw rod 11, and the upper part of the screw rod pair 13 extends out of the upper part of the connecting box 2 8 and is connected to a rotating seat 14.

[0025] Furthermore, the connection box 1 5 and the connection box 2 8 are connected to each other.

[0026] Furthermore, a plurality of fastening fixtures 4 are installed on the upper portion of the platform 1 .

[0027] Furthermore, one end of the worm 10 passes through the connecting box 2 8 and rotates inside the box, and a screw rod 11 is installed below the worm 10, both ends of the screw rod 11 are rotatably installed on the inner wall of the connecting box 2 8, and a worm wheel 12 is fixedly installed in the middle of the screw rod 11, and the worm wheel 12 is meshingly connected with the worm 10.

[0028] Furthermore, a sliding groove 16 is provided on the upper portion of the second connection box 8 , and a screw pair 13 is installed in the sliding groove 16 in a limited sliding manner.

[0029] Furthermore, a connecting rod 15 is rotatably installed on the upper part of the rotating seat 14, and the other end of the connecting rod 15 is rotatably installed on the middle part of the outer side of the support arm 6, and the other end of the support arm 6 is rotatably installed on one side inside the limiting groove 7, and in a natural state, the support arm 6 is embedded in the limiting groove 7.

[0030] In this embodiment, by rotating the driving head 9 provided at the bottom of the platform 1, the driving head 9 drives the worm 10 to rotate, and the worm 10 drives the lead screw 11 to rotate and makes the lead screw pair 13 move horizontally. Under the action of the connecting rod 15, the support arm 6 provided on the platform 1 is tilted. At this time, one end of the test piece 3 can be connected to the tooth groove test block 2, and the other end is installed on the support arm 6. At the same time, the support arm 6 is lowered to complete the test installation purpose of the test piece 3, and then the test piece 3 is locked by the fastening fixture 4 to ensure the detection stability and test accuracy.

[0031] Among them, in actual use, the driving head 9 rotates and drives the worm 10 to rotate. The worm 10 rotates in the two connecting boxes 5 set at the bottom of the platform 1, and when the worm 10 rotates, the worm wheel 12 set in the connecting box 5 is rotated through the tooth groove engagement transmission. The worm wheel 12 drives the screw 11 to rotate under the driving action of the worm 10. The screw 11 rotates and drives the screw pair 13 to move horizontally through the thread rotation. The screw pair 13 drives the rotating seat 14 to move in the sliding groove 16 opened on the connecting box 8, and drives the connecting rod 15 to move horizontally. Since one end of the connecting rod 15 is limited by the support arm 6, the connecting rod 15 pushes the support arm 6 and makes the support arm 6 rotate to one side of the limiting groove 7, thereby realizing the lifting function of the support arm 6.

[0032] Among them, in actual use, the connection box 1 5 and the connection box 2 8 are used to protect the internal driving parts.

[0033] Among them, it is worth noting that the fastening clamp 4 is rotated by the handle so that the locking piece presses the surface of the test piece 3, which can be achieved by any track shoe inspection fixture on the market. The specific structure and operating principle not described in detail above are technical common sense known to people in this field.

[0034] In the utility model, the test piece 3 is placed on the platform 1 and tested through the detection blocks on both sides. At the same time, during the detection process of the test piece 3, the support arm 6 set on the upper part of the platform can be rotated by the drive head 9 in cooperation with the internal drive mechanism, so that the number of manual interventions in the process of taking and placing the test piece is reduced, the risk is reduced, the convenience of test installation is improved, and the detection efficiency is improved.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
