[0043] Reference Figures 1 to 3 The present invention relates to a caliper sliding force testing device, comprising: a support frame 100, with a mounting bracket 110 on one side, and a caliper 120 mounted on the mounting bracket 110; a drive member 200, located on the other side of the support frame 100; a test piece 300, located at the output end of the drive member 200, with the caliper 120 clamping the test piece 300; a first sensor 400 located on the side of the test piece 300 near the drive member 200, the first sensor 400 being used to measure the resistance experienced by the test piece 300; and a second sensor 500 located on the support frame 100, with the test end of the second sensor 500 abutting against the test piece 300, the second sensor 500 being used to measure the displacement of the test piece 300.

[0044] The above-mentioned caliper sliding force testing device has at least the following beneficial effects: the test piece 300 is clamped by the externally driven caliper 120, and the test piece 300 is driven to move away from the caliper 120 by the driving component 200. The resistance magnitude of the test piece 300 is measured by the first sensor 400 on the test piece 300, and the displacement of the test piece 300 is measured by the second sensor 500. The force-displacement curve is obtained, and the sliding force of the caliper 120 can be determined and calculated. The overall structure is simple, the test data is accurate, and the test efficiency is high.

[0045] According to some embodiments of this utility model, the test piece 300 includes a test plate 310, a connecting plate 320, and a mounting plate 330. The test plate 310 and the mounting plate 330 are connected through the connecting plate 320. The clamp 120 is clamped on the test plate 310. The mounting plate 330 is located at the output end of the drive component 200. The first sensor 400 is located on the mounting plate 330. The test end of the second sensor 500 abuts against the mounting plate 330. The test piece also includes a guide rod 130. The mounting plate 330 is provided with a guide sleeve 340. One end of the guide rod 130 is located on the support frame 100. The guide sleeve 340 is movably connected to the other end of the guide rod 130. The guide sleeve 340 slides on the guide rod 130 to guide the displacement of the mounting plate 330 and avoid displacement deviation that could damage the drive component 200 or cause inaccurate test data.

[0046] According to some embodiments of the present invention, the driving component 200 is configured as a cylinder; in some other embodiments, the driving component 200 may also be configured as a linear motor.

[0047] According to some embodiments of this utility model, an angle adjustment component is also included. The support frame 100 is connected to the angle adjustment component, which includes: a first base 600; a worm gear mechanism 610 disposed on the base; a rotating rod 620 movably connected to the worm gear mechanism 610, one end of the rotating rod 620 being bolted to the support frame 100, and the other end being connected to a locking mechanism; a bearing disposed on the first base 600 via a bearing seat 630, with the rod body of the rotating rod 620 movably disposed on the bearing; and an adjusting component connected to the worm gear mechanism 610, used to drive the worm gear mechanism 610 to rotate, thereby driving the rotating rod 620 to rotate. The adjusting component drives the worm gear mechanism 610 to rotate, thus driving the rotating rod 620 to rotate, so that the rotating rod 620 rotates together with the support frame 100, allowing the caliper 120 on the support frame 100 to be at different installation angles for measuring the sliding force, simulating the caliper 120 under various installation angles, making the measurement data more accurate.

[0048] According to some embodiments of this utility model, the adjusting component is a rotating handle 640 or a motor.

[0049] According to some embodiments of the present invention, the locking mechanism includes a locking block 650 and a locking handle 660. The locking block 650 is disposed on the first base 600. The locking block 650 is provided with a through hole and an opening groove communicating with the through hole. The other end of the rotating rod 620 is disposed in the through hole. The locking handle 660 is threadedly connected to the side of the opening groove. After the opening groove is locked by the locking handle 660, the through hole clamps the rotating rod 620 and prevents it from rotating by friction, thereby locking the installation angle of the support frame 100 and the caliper 120.

[0050] According to some embodiments of this utility model, a second base 670 is also included. The first base 600 and the second base 670 are respectively disposed on both sides of the support frame 100. The second base 670 is provided with a bearing seat 630 and a locking mechanism. The bearing seat 630 is provided with a bearing, and a rotating rod 620 is movably connected in the bearing. One end of the rotating rod 620 is connected to the support frame 100, and the other end is connected to the locking mechanism. Through the above-mentioned structure on the second base 670, the structure on the first base 600 can play an auxiliary support role, avoiding the situation where the center of gravity of the support frame 100 tilts, resulting in inaccurate rotation angle, or causing the caliper 120 to be interfered with by external force, resulting in inaccurate measurement structure.

[0051] According to some embodiments of the present invention, the first base 600 is also provided with an angle scale 680, which is used to determine the rotation angle of the support frame 100.

[0052] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.

[0053] Although some embodiments of the present invention have been shown and described in this specification, the present invention should not be limited to the above embodiments. As long as they achieve the technical effects of the present invention by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles of this disclosure, without departing from the principles and purpose of the present invention, should be included within the scope of protection of this disclosure and should be considered to fall within the protection scope of the present invention.
