[0017] The method for using the automobile parts testing device includes the following steps:

[0018] Step 1: Install the suspension link. First, put the automobile suspension link to be tested into the protective cover along the feed inlet. When the suspension link enters the protective cover along the feed inlet, the suspension link passes through the fixed ring along the expanded fixed clamping plate. At this time, the fixed clamping plate in the expanded state is conducive to guiding the suspension link, so as to facilitate the suspension link to pass through the fixed ring smoothly. At this time, the suspension link slides along the fixed ring toward the end close to the rotating cylinder. When the suspension link contacts the inclined slope at one end of the fastening head, under the guiding effect of the inclined slope, the suspension link squeezes the sliding sheet 1 along the rotating cylinder;

[0019] Step 2: fix the rotating end of the suspension connecting rod, drive the motor to rotate to drive the output shaft to rotate, the output shaft rotates to drive the sliding plate on the threaded groove at one end of the output shaft to slide along the sliding groove toward the end away from the driving motor, the sliding of the sliding plate drives the pushing ring at one end of the pushing rod to slide to the right, the pushing ring drives the rotating ring to slide to the right along the surface of the rotating cylinder, the sliding of the rotating ring is squeezed with the squeezing rod on the surface of the rotating cylinder, the squeezing rod is squeezed to drive the sliding block at the other end of the squeezing rod to squeeze the squeezing spring downward along the squeezing groove, at this time the sliding block moves downward to drive the fastening sheet at one end of the telescopic rod to move toward the outer wall of the rotating end of the suspension connecting rod, at this time the fastening sheet is squeezed with the outer wall of the rotating end of the suspension connecting rod;

[0020] Step 3: Fix the fixed end of the suspension connecting rod. When the output shaft rotates, the sliding plate on the threaded groove at one end of the output shaft slides along the sliding groove toward the end away from the driving motor. The sliding of the sliding plate drives the pushing ring at one end of the pushing rod to slide to the right. The pushing ring slides to the right and drives the fastening ring at one end of the connecting rod to slide to the right along the fixed clamping plate. At this time, the fastening ring and the fixed clamping plate are squeezed. The fixed clamping plate is squeezed and drives the clamping wedge to squeeze the outer wall of the fixed end of the suspension connecting rod.

[0021] Step 4: squeeze the suspension connecting rod. When the output shaft rotates, the sliding plate on the threaded groove at one end of the output shaft slides along the sliding groove toward the end away from the driving motor. When several balls 2 on the sliding plate are squeezed with the groove on one side of the sliding ring, the sliding ring slides along the output shaft toward the end close to the rotating cylinder. The sliding ring drives the sliding sheet 2 at one end of the telescopic rod 2 to be squeezed with the reset spring. The reset spring is squeezed and contracted, and the contraction elastic force of the reset spring increases.

[0022] The present invention has the following beneficial effects:

[0023] (1) The present invention sets a rotating end fixing mechanism. When the rotating end of the suspension connecting rod enters the interior of the rotating cylinder, the driving motor is started by controlling the detection control panel. The driving motor rotates to drive the output shaft to rotate. The output shaft rotates to drive the sliding plate on the threaded groove at one end of the output shaft to slide along the sliding groove toward the end away from the driving motor. The sliding of the sliding plate drives the pushing ring at one end of the pushing rod to slide to the right. The pushing ring drives the rotating ring to slide to the right along the surface of the rotating cylinder. The sliding of the rotating ring is squeezed by the squeezing rod on the surface of the rotating cylinder. The squeezing rod is squeezed and drives the sliding block at the other end of the squeezing rod to squeeze downward along the squeezing groove. Spring, at this time the sliding block moves downward to drive the fastening plate at one end of the telescopic rod to move toward the outer wall of the rotating end of the suspension link. At this time, the fastening plate is squeezed against the outer wall of the rotating end of the suspension link. This arrangement is conducive to the output shaft rotating to drive the rotating cylinder to rotate, and the rotating cylinder rotates to drive the suspension link on the fastening plate to rotate, thereby giving an axial shear force to the rotating end of the suspension link; by arranging a number of ball bearings between the pushing ring and the rotating ring, it is conducive to the rotating cylinder driving the suspension link to rotate, thereby reducing the friction between the pushing ring and the rotating ring, thereby reducing the loss of shear force at the rotating end of the suspension link, thereby ensuring the accuracy of the test device.

[0024] (2) According to the present invention, when the automobile parts testing device is used, the automobile suspension link to be tested is first placed into the protective cover along the feed inlet. When the suspension link enters the protective cover along the feed inlet, the suspension link passes through the fixed ring along the expanded fixed clamp. At this time, the fixed clamp in the expanded state helps to guide the suspension link, thereby facilitating the suspension link to pass through the fixed ring smoothly. At this time, the suspension link slides along the fixed ring toward one end close to the rotating cylinder. When the suspension link contacts the inclined slope at one end of the fastening head, under the guiding effect of the inclined slope, the suspension link squeezes the sliding plate along the rotating cylinder. This arrangement is conducive to quickly and accurately placing the suspension link into the test component, thereby improving the working efficiency of the testing device.

[0025] (3) The present invention sets a fixed end fixing mechanism. When the output shaft rotates, the sliding plate on the threaded groove at one end of the output shaft slides along the sliding groove toward the end away from the driving motor. The sliding of the sliding plate drives the pushing ring at one end of the pushing rod to slide to the right. The pushing ring slides to the right and drives the fastening ring at one end of the connecting rod to slide to the right along the fixed clamping plate. At this time, the fastening ring and the fixed clamping plate are squeezed. The fixed clamping plate is squeezed and drives the clamping wedge to squeeze the outer wall of the fixed end of the suspension connecting rod. This arrangement is conducive to the clamping wedge to fix the fixed end of the suspension connecting rod, thereby ensuring that the fixed end of the suspension connecting rod will not rotate with the rotating end during testing; in conjunction with the rotating end The function of the rotating end fixing mechanism is that the rotating end fixing mechanism gives axial shear force to the rotating end of the suspension link, and the fixed end fixing mechanism fixes the fixed end of the suspension link to ensure that the shear force on the suspension link remains unchanged. When one end of the suspension link is fixed on the fixed end fixing mechanism, when the clamping of the fixed end fixing mechanism is loose, the output shaft drives the rotating cylinder to rotate. At this time, the pushing ring in the rotating end fixing mechanism drives the fastening ring at one end of the connecting rod to continue to slide along the fixed clamping plate. At this time, the fixed clamping plate drives the clamping wedge to squeeze the suspension link with greater force, thereby ensuring that the fixing effect of the fixed end fixing mechanism on the fixed end of the suspension link remains stable.

[0026] (4) The present invention provides an extrusion mechanism. When the output shaft rotates, the sliding plate on the threaded groove at one end of the output shaft slides along the sliding groove toward the end away from the driving motor. When a plurality of ball bearings 2 on the sliding plate are pressed against the groove on one side of the sliding ring, the sliding ring slides along the output shaft toward the end close to the rotating cylinder. The sliding ring drives the sliding sheet 2 at one end of the telescopic rod 2 to be pressed against the reset spring. The reset spring is squeezed and contracted, and the contraction elastic force of the reset spring increases. Therefore, the force of the reset spring on the suspension link at the one end of the sliding sheet 1 increases. Such a configuration is conducive to improving the stability of the suspension link, thereby ensuring that the suspension link will not fall off during the test.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The method for using the automobile parts testing device includes the following steps:

[0054] Step 1: Install the suspension link. First, place the automobile suspension link to be tested into the protective cover 203 along the feed port 202. When the suspension link enters the protective cover 203 along the feed port 202, the suspension link passes through the fixed ring 301 along the expanded fixed clamping plate 302. At this time, the fixed clamping plate 302 in the expanded state is conducive to guiding the suspension link, so as to facilitate the suspension link to pass through the fixed ring 301 smoothly. At this time, the suspension link slides along the fixed ring 301 to the end close to the rotating cylinder 209. When the suspension link contacts the inclined slope 501 at one end of the fastening head 409, under the guidance of the inclined slope 501, the suspension link squeezes the sliding sheet 1 502 along the rotating cylinder 209;

[0055] Step 2: Fix the rotating end of the suspension link, and the drive motor 13 rotates to drive the output shaft 207 to rotate. The rotation of the output shaft 207 drives the sliding plate 402 on the threaded groove 208 at one end of the output shaft 207 to slide along the sliding groove 401 toward the end away from the drive motor 13. The sliding of the sliding plate 402 drives the pushing ring 404 at one end of the pushing rod 403 to slide to the right. The pushing ring 404 drives the rotating ring 405 to slide to the right along the surface of the rotating cylinder 209. The sliding of the rotating ring 405 is squeezed with the squeezing rod 407 on the surface of the rotating cylinder 209. The squeezing rod 407 is squeezed and drives the sliding block 412 at the other end of the squeezing rod 407 to squeeze the squeezing spring 411 downward along the squeezing groove 410. At this time, the sliding block 412 moves downward to drive the fastening piece 414 at one end of the telescopic rod 413 to move toward the outer wall of the rotating end of the suspension link. At this time, the fastening piece 414 is squeezed with the outer wall of the rotating end of the suspension link.

[0056] Step 3: Fix the fixed end of the suspension connecting rod. When the output shaft 207 rotates, the sliding plate 402 on the threaded groove 208 at one end of the output shaft 207 slides along the sliding groove 401 toward the end away from the driving motor 13. The sliding of the sliding plate 402 drives the pushing ring 404 at one end of the pushing rod 403 to slide to the right. The pushing ring 404 slides to the right and drives the fastening ring 305 at one end of the connecting rod 304 to slide to the right along the fixed clamping plate 302. At this time, the fastening ring 305 and the fixed clamping plate 302 are squeezed. The fixed clamping plate 302 is squeezed and drives the clamping wedge block 303 to squeeze the outer wall of the fixed end of the suspension connecting rod.

[0057] Step 4: Squeeze the suspension connecting rod. When the output shaft 207 rotates, the sliding plate 402 on the threaded groove 208 at one end of the output shaft 207 slides along the sliding groove 401 toward the end away from the drive motor 13. When the several ball bearings 508 on the sliding plate 402 are squeezed with the groove on one side of the sliding ring 507, the sliding ring 507 slides along the output shaft 207 toward the end close to the rotating cylinder 209. The sliding ring 507 drives the sliding sheet 2 504 at one end of the telescopic rod 2 505 to be squeezed with the return spring 503. The return spring 503 is squeezed and contracted, and the contraction elastic force of the return spring 503 increases.

[0058] A specific application of this embodiment is:

[0059] When the automobile parts testing device is used, the automobile suspension link to be tested is first placed into the protective cover 203 along the feed port 202. When the suspension link enters the protective cover 203 along the feed port 202, the suspension link passes through the fixing ring 301 along the expanded fixing clamp 302. At this time, the fixing clamp 302 in the expanded state is conducive to guiding the suspension link, thereby facilitating the suspension link to pass through the fixing ring 301 smoothly. At this time, the suspension link slides along the fixing ring 301 toward the end close to the rotating cylinder 209. When the suspension link contacts the inclined slope 50 at one end of the fastening head 409, the suspension link is pulled out of the protective cover 203. 1, under the guidance of the inclined slope 501, the suspension link squeezes the sliding plate 502 along the rotating cylinder 209, so that it is convenient to quickly and accurately put the suspension link into the test component, thereby improving the working efficiency of the test device; by setting the rotating end fixing mechanism 4, when the rotating end of the suspension link enters the rotating cylinder 209, the driving motor 13 is started by controlling the detection control panel 14, and the driving motor 13 rotates to drive the output shaft 207 to rotate, and the output shaft 207 rotates to drive the sliding plate 402 on the threaded groove 208 at one end of the output shaft 207 to slide along the sliding plate The groove 401 slides toward the end away from the driving motor 13, and the sliding plate 402 slides to drive the pushing ring 404 at one end of the pushing rod 403 to slide to the right, and the pushing ring 404 drives the rotating ring 405 to slide to the right along the surface of the rotating cylinder 209, and the rotating ring 405 slides and squeezes the squeezing rod 407 on the surface of the rotating cylinder 209. The squeezing rod 407 is squeezed and drives the sliding block 412 at the other end of the squeezing rod 407 to squeeze the squeezing spring 411 downward along the squeezing groove 410. At this time, the sliding block 412 moves downward to drive the fastening piece 414 at one end of the telescopic rod 413 to move toward the outer wall of the rotating end of the suspension connecting rod. At this time, the fastening sheet 414 is pressed against the outer wall of the rotating end of the suspension link. This arrangement is conducive to the output shaft 207 rotating to drive the rotating cylinder 209 to rotate, and the rotating cylinder 209 rotating to drive the suspension link on the fastening sheet 414 to rotate, thereby giving an axial shear force to the rotating end of the suspension link; by arranging a plurality of balls 406 between the pushing ring 404 and the rotating ring 405, it is conducive to the rotating cylinder 209 driving the suspension link to rotate, thereby reducing the friction between the pushing ring 404 and the rotating ring 405, thereby reducing the loss of shear force at the rotating end of the suspension link, thereby ensuring the accuracy of the test device;

[0060] By setting the fixed end fixing mechanism 3, when the output shaft 207 rotates, the sliding plate 402 on the threaded groove 208 at one end of the output shaft 207 slides along the sliding groove 401 toward the end away from the drive motor 13, the sliding plate 402 slides and drives the pushing ring 404 at one end of the pushing rod 403 to slide to the right, and the pushing ring 404 slides to the right and drives the fastening ring 305 at one end of the connecting rod 304 to slide to the right along the fixed clamping plate 302. At this time, the fastening ring 305 and the fixed clamping plate 302 are squeezed, and the fixed clamping plate 302 is squeezed and drives the clamping wedge 303 to the fixed end of the suspension connecting rod. The outer walls of the fixed ends are squeezed against each other, and this arrangement is conducive to clamping the wedge block 303 to fix the fixed end of the suspension link, thereby ensuring that the fixed end of the suspension link will not rotate with the rotating end during testing; in conjunction with the function of the rotating end fixing mechanism 4, the rotating end fixing mechanism 4 gives an axial shear force to the rotating end of the suspension link, and the fixed end fixing mechanism 3 fixes the fixed end of the suspension link to ensure that the shear force on the suspension link remains unchanged. When one end of the suspension link is fixed to the fixed end fixing mechanism 3, when the clamping of the fixed end fixing mechanism 3 is loose, the output shaft 207 drives the rotating cylinder 209 to rotate The push ring 404 in the rotating end fixing mechanism 4 drives the fastening ring 305 at one end of the connecting rod 304 to continue to slide along the fixed clamping plate 302. At this time, the fixed clamping plate 302 drives the clamping wedge 303 to squeeze the suspension connecting rod with greater force, thereby ensuring that the fixing effect of the fixed end fixing mechanism 3 on the fixed end of the suspension connecting rod remains stable; by setting the squeezing mechanism 5, when the output shaft 207 rotates and drives the sliding plate 402 on the threaded groove 208 at one end of the output shaft 207 to slide along the sliding groove 401 toward the end away from the driving motor 13, when several When the second ball 508 is pressed against the groove on one side of the sliding ring 507, the sliding ring 507 slides along the output shaft 207 to the end close to the rotating cylinder 209, and the sliding ring 507 drives the sliding piece 2 504 at one end of the telescopic rod 2 505 to be pressed against the return spring 503. The return spring 503 is squeezed and contracted, and the contraction elastic force of the return spring 503 increases. Therefore, the force of the return spring 503 on the suspension link at one end of the sliding piece 1 502 increases. This arrangement is conducive to improving the stability of the suspension link, thereby ensuring that the suspension link will not fall off during the test.
