Description

Technical Field

[0001] The utility model relates to a wear-resistant test bench, in particular to a wear-resistant test device for an elevator operation panel. Background Art

[0002] In the field of industrial production, as a key component of many devices, the wear resistance of the operation panel is directly related to the service life and stability of the device. In order to ensure the quality of the operation panel, wear-resistant testing has become an indispensable detection link. There are various types of existing wear-resistant test benches, but most of them have some limitations.

[0003] The workpiece clamping device of the common test bench is not stable enough. There is a positioning shell on the positioning ring. Inside the positioning shell, a positioning arm is connected through a spring. The elastic force of the spring is used to squeeze the positioning arm, so that the positioning arm meshes with the positioning gear. Due to the high-speed reciprocating speed of the workpiece, the generated frictional force is not enough to make the positioning arm perfectly mesh with the positioning gear, resulting in the rotation of the outer shell, reducing the wear-resistant test efficiency. At the same time, it is impossible to ensure the precise positioning of the workpiece during high-speed reciprocating motion, which easily leads to deviation of the test results. Content of the Utility Model

[0004] The utility model aims to provide a wear-resistant test device for an elevator operation panel, which solves the problems that in the prior art, due to insufficient elastic force of the spring in the positioning mechanism, the outer shell deflects during wear-resistant testing, resulting in deviation of the test results and low efficiency.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1As shown in the figure, the present utility model provides a wear resistance test device for an elevator operation panel, comprising: a workbench 1, a clamping device 3, a fixing frame 4 and a detection execution device 5; a guiding groove 11 is formed at the top of the workbench 1, and a driving device (not shown in the figure) is arranged inside the workbench 1. The output end of the driving device passes through the guiding groove 11 and is connected to the bottom of the clamping device 3. The driving device is used to drive the clamping device 3 to move back and forth in the X direction; the clamping part on the clamping device 3 is used to clamp the workpiece to be detected; the bottom of the fixing frame 4 is installed on the workbench 1, and a support rod 41 is installed on one side of the fixing frame 4 close to the clamping device 3; the detection execution device 5 comprises: a rotating outer shell 51, a first screw rod 52, a threaded sleeve 53, a positioning mechanism 54, a first clamping mechanism 55 and a test contact member 56. A rotatable rotating outer shell 51 is installed on the support rod 41. One end of the first screw rod 52 is connected to the inner wall of the rotating outer shell 51, and the other end of the first screw rod 52 is provided with a first clamping mechanism 55. A test contact member 56 is arranged in the clamping cavity of the first clamping mechanism 55. The test contact member 56 contacts the surface of the workpiece to be detected. The threaded sleeve 53 is threadedly connected to the first screw rod 52. The threaded sleeve 53 is used to push the first clamping mechanism 55 to clamp the test contact member 56. One end of the threaded sleeve 53 away from the first clamping mechanism 55 is movably connected to a positioning mechanism 54, and the positioning mechanism 54 can limit the rotation of the rotating outer shell 51.

[0023] The working principle is to place the workpiece to be detected in the clamping part of the clamping device 3 and clamp it. The driving device drives the clamping device 3 to move back and forth in the X direction along the guiding groove 11 on the workbench 1. At the same time, the rotating outer shell 51 in the detection execution device 5 rotates on the support rod 41. One end of the first screw rod 52 is connected to the inner wall of the rotating outer shell 51, and the other end is connected to the first clamping mechanism 55 with the test contact member 56. The threaded sleeve 53 is threadedly connected to the first screw rod 52. By rotating the threaded sleeve 53, the first clamping mechanism 55 is pushed, so that the first clamping mechanism 55 clamps the test contact member 56, and the test contact member 56 is in close contact with the surface of the workpiece to be detected. The positioning end of the positioning mechanism 54 cooperates with the limiting gear 541 to limit the rotation of the rotating outer shell 51. Thus, when the clamping device 3 drives the workpiece to move, the test contact member 56 performs a wear resistance test on the surface of the workpiece.

[0024] As Figure 3As shown in the figure, the positioning mechanism 54 includes a limit gear 541, a positioning ring 542, and a positioning arm 543. A limit gear 541 is provided at the end of the support rod 41. The limit gear 541 cannot rotate relative to the support rod 41. The positioning ring 542 is sleeved on the first screw rod 52. The positioning ring 542 can move relative to the first screw rod 52, and the positioning ring 542 cannot rotate relative to the first screw rod 52. The positioning ring 542 is rotatably connected to one end of the threaded sleeve 53 away from the first clamping mechanism 55. The threaded sleeve 53 can drive the positioning ring 542 to move in the axial direction of the first screw rod 52. A positioning arm 543 is fixed to one end of the positioning ring 542 away from the threaded sleeve 53. A positioning tooth 545 is provided on one side of the positioning arm 543 close to the limit gear 541. The positioning tooth 545 can be engaged with the limit gear 541. During operation, when the threaded sleeve 53 is rotated to make the first screw rod 52 move downward, the threaded sleeve 53 drives the positioning ring 542 to move downward. When the threaded sleeve 53 presses the first clamping mechanism 55, the positioning tooth 545 on the positioning arm 543 is engaged with the limit gear 541 to limit the rotation of the first screw rod 52 and keep the test contact 56 in contact with the surface of the workpiece to be detected.

[0025] A guide block 544 is provided on the side surface of the positioning ring 542. A sliding groove (not shown in the figure) is formed on the inner wall of the rotating housing 51. The guide block 544 can slide in the sliding groove. The guide block 544 is used to limit the rotation of the positioning ring 542 relative to the first screw rod 52, so as to ensure that the meshing position of the positioning tooth 545 and the limit gear 541 does not change.

[0026] As Figure 4 shown in the figure, the first clamping mechanism 55 includes a clamping arm 551, an elastic ring 552, a hinged ring 553, and a fixed seat 554. One end of the clamping arm 551 is a clamping part. The other end of the clamping arm 551 can be surrounded by the elastic ring 552. The elastic ring 552 is used to keep all clamping parts in an open state. The hinged ring 553 passes through the middle of the clamping arm 551. The hinged ring 553 is installed on the inner wall of the first screw rod 52 through the fixed seat 554. The clamping arm 551 can rotate around the hinged ring 553. The threaded sleeve 53 is used to push the clamping part to clamp the test contact 56. When the threaded sleeve 53 is rotated and moves to the first clamping mechanism 55, the inner wall of the threaded sleeve 53 presses the clamping arm 551 to clamp the test contact 56 by the clamping arm 551. When the test is completed, the threaded sleeve 53 is rotated upward to release the clamping arm 551, and the elastic force of the elastic ring 552 is used to make the clamping arm 551 rotate around the hinged ring 553 to release the clamping part from the test contact 56 for convenient replacement or removal.

[0027] The clamping device includes a support plate 31 and a second clamping mechanism 32. The support plate 31 is connected to the output end of the driving device. The second clamping mechanism 32 is installed on the support plate 31. The second clamping mechanism 32 is used to clamp the workpiece to be detected.

[0028] As Figure 2As shown, the second clamping mechanism 32 includes: a mounting plate 321, a first clamping block 322, a second clamping block 323, a guide rod 324 and a second screw 325. The mounting plate 321 and the first clamping block 322 are fixedly connected to the support plate 31, the first clamping block 322 is located between the mounting plate 321 and the fixing frame 4, the mounting plate 321 is threadedly connected with the second screw 325, and guide rods 324 are provided on both sides of the second screw 325. The guide rods 324 are connected to the second clamping block 323 at one end close to the first clamping block 322, and a pressing block 326 is provided at one end of the second screw 325 close to the second clamping block 323. The second screw 325 can rotate relative to the pressing block 326, and the pressing block 326 is a cover-shaped structure. The second screw 325 is fixed with an anti-dropping cap 327 (the anti-dropping cap is installed on the second screw 325 by welding or the like, as shown in FIG. Figure 5 As shown in the figure, the anti-drop cap 327 is located in the pressing block 326, the pressing block 326 is fixedly connected to the second clamping block 323, and the first clamping block 322 cooperates with the second clamping block 323 to clamp the workpiece to be detected. During operation, the mounting plate 321 and the first clamping block 322 are fixed on the support plate 31, the second screw 325 is threadedly connected to the mounting plate 321, and the guide rods 324 on both sides ensure the stability of the second clamping block 323 when it moves. When the second screw 325 is rotated, the pressing block 326 near one end of the second clamping block 323 pushes the second clamping block 323 to move along the guide rod 324, and the first clamping block 322 cooperates with the second clamping block 323 to firmly clamp the workpiece to be detected. The workflow for removing the workpiece to be inspected is as follows: rotate the second screw 325 so that the anti-drop cap 327 on the second screw 325 drives the second clamping block 323 to move through the pressing block 326, and then the second clamping block 323 releases the workpiece to be inspected.

[0029] The test contact member 56 is a metal detection rod 561. The metal detection rod 561 performs reciprocating friction on the surface of the workpiece, and the wear resistance of the workpiece surface is evaluated through a certain number of frictions or a certain time of testing.

[0030] There are at least three clamping arms 551. The three clamping arms 551 balance the force on the workpiece, preventing the workpiece from being displaced or shaken due to uneven force during the inspection process.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
