[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] See also Figure 1 —4. A light truck cast aluminum base plate testing device, comprising a frame 1, and a transmission assembly 2 arranged on the frame 1; a mounting frame 11 is provided on the top of the frame 1; a pressure assembly 3 is provided on the mounting frame 11; a movable unit 4 is provided inside the frame 1; the movable unit 4 comprises a guide wheel 41, a mounting seat 42 and a fixed seat 43; the fixed seat 43 is fixedly mounted on the frame 1; a slide groove is provided on the outer wall of the fixed seat 43 and one side of the frame 1; the fixed seat 43 is slidably connected in the slide groove; the guide wheel 41 is rotatably connected to the mounting seat 42; a decompression spring is provided between the mounting seat 42 and the fixed seat 43; a fixing assembly 5 is provided inside the frame 1.

[0023] Specifically, such as Figure 2 As shown, a fixing plate 12 is fixedly provided inside the frame 1, and a through slot 13 is symmetrically opened on the outer wall on one side of the fixing plate 12. A transmission component 2 is provided on the fixing plate 12, and the transmission component 2 can drive the workpiece to be tested to keep moving on the fixing plate 12. A mounting frame 11 is provided on the top of the frame 1, and a pressure component 3 is provided on the mounting frame 11. The pressure component 3 is arranged in an array on the mounting frame 11, so that different positions on the workpiece to be tested can be tested.

[0024] As a further embodiment provided by the present invention, Figure 2 and Figure 4 As shown, the movable unit 4 includes a guide wheel 41, a mounting seat 42 and a fixed seat 43. Furthermore, the fixed seat 43 is fixedly mounted on the outer wall of one side of the fixed plate 12. A slide groove is provided on the outer wall of the fixed seat 43 and the outer wall of one side of the fixed plate 12. The guide wheel 41 is rotatably connected to the inside of the mounting seat 42 through a shaft, and the two ends of the shaft respectively pass through the two sides of the mounting seat 42. The mounting seat 42 is slidably connected to the slide groove through the shaft on the outer walls on both sides. A decompression spring is provided between the outer wall of the mounting seat 42 and the inner wall of one side of the fixed seat 43. The decompression spring can drive the mounting seat 42 to move toward one side. Then, the guide wheel 41 inside the mounting seat 42 can contact the workpiece to be measured that enters the frame 1. When the workpiece to be measured collides with the guide wheel 41, since the guide wheel 41 is movably connected to the slide groove through the mounting seat 42, it can keep sliding in the slide groove, achieving the effect of soft contact with the workpiece to be measured. At the same time, since a decompression spring is provided between the mounting seat 42 and the fixed seat 43, the decompression spring can drive the mounting seat 42 to move away from the fixed seat 43, so that the guide wheel 41 can always be in contact with the outer wall of the workpiece to be measured, thereby facilitating the workpiece to be measured to keep moving inside the frame 1.

[0025] Preferably, Figure 1 and Figure 2 As shown, there are several movable units 4 , which are symmetrically distributed inside the rack 1 .

[0026] A fixing assembly 5 is provided on an outer wall of one side of the fixing plate 12 , and the workpiece to be measured can be kept fixedly connected to the frame 1 through the fixing assembly 5 .

[0027] The utility model drives the test workpiece to move inside the frame 1 through the transmission component 2 provided inside the frame 1. When the test workpiece is placed inside the frame 1, the guide wheel 41 of the movable unit 4 contacts the edge of the test workpiece, and the pressure relief spring provided between the mounting seat 42 and the fixed seat 43 bears the impact, thereby reducing the impact force of the collision between the test workpiece and the movable unit 4, thereby reducing damage to the test workpiece. The test workpiece can be fixed by providing a fixing component 5 inside the frame 1. The pressure component 3 provided on the top of the frame 1 can apply pressure to the surface of the test workpiece, thereby realizing a load-bearing strength test of the test workpiece. The load-bearing strength test of the test workpiece can be carried out conveniently and quickly, and at the same time, it can provide a certain degree of protection for the test workpiece when the test workpiece enters the frame 1.

[0028] As an embodiment provided by the present utility model, Figure 2 As shown, the fixing assembly 5 includes a support base 51, a fixed cylinder 52 and a fixed block 53. Specifically, the support base 51 is an "L"-shaped structure. The support base 51 is fixedly mounted on the fixed plate 12. The fixed cylinder 52 is fixedly mounted on the top of the support base 51. The output end of the fixed cylinder 52 passes through the support base 51. The fixed block 53 is fixedly mounted on the output end of the fixed cylinder 52. The fixed cylinder 52 can drive the fixed block 53 to keep moving inside the support base 51, and then the fixed block 53 can be used to abut against the workpiece to be measured to fix the workpiece to be measured on the fixed plate 12.

[0029] As a further embodiment provided by the present invention, Figure 3 and Figure 4 As shown, the transmission assembly 2 includes a drive motor 21, a drive wheel 22, a transmission wheel 23 and a transmission belt 24. Figure 3 and Figure 4 As shown, the drive motor 21 is fixedly mounted on the outer wall of one side of the fixed plate 12, the drive wheel 22 is fixedly connected to the output end of the drive motor 21, and there are two transmission wheels 23. The two transmission wheels 23 are rotatably connected to the two ends of the fixed plate 12 respectively. The transmission belt 24 is connected to the two transmission wheels 23 and the drive wheel 22. The drive motor 21 drives the drive wheel 22 to keep rotating, and then the drive wheel 22 drives the transmission belt 24 to keep rotating. The rotation of the transmission belt 24 drives the transmission wheel 23 to assist in rotation, and finally the workpiece to be measured is moved on the fixed plate 12 by the transmission belt 24. It should be pointed out that the number of transmission wheels 23 can be increased to ensure that the workpiece to be measured can move smoothly.

[0030] As an embodiment provided by the present invention, the pressure component 3 is fixedly installed on the mounting frame 11. As one of the embodiments provided by the present invention, the pressure component 3 can be a hydraulic cylinder, which applies static load pressure to the workpiece to be tested through the hydraulic cylinder, so as to test the bearing capacity of the workpiece to be tested.

[0031] As another embodiment of the present invention, the pressure component 3 includes a winding motor 31, a winding rod 32, a connecting chain and an impact head. Figure 2 and Figure 1 As shown, the winding rod 32 is rotatably connected to the outer wall of the mounting frame 11, and the winding motor 31 is fixedly installed on the outer wall of one side of the mounting frame 11. The output end of the winding motor 31 maintains a transmission connection with the winding rod 32, and the winding motor 31 can drive the winding rod 32 to keep rotating. One end of the connecting chain is fixedly connected to the impact head, and the other end of the connecting chain is connected to the winding rod 32. The connecting chain can be wound up by driving the winding rod 32 to keep rotating by the winding motor 31, and then the impact head on the connecting chain can be lifted.

[0032] Further, such as Figure 2 As shown, the pressure-applying assembly 3 also includes a telescopic cylinder 35, a transmission joint 36, a linkage joint 37 and a connecting plate 38. The telescopic cylinder 35 is fixedly mounted on the outer wall of one side of the mounting frame 11, the linkage joint 37 is fixed on one end of the winding rod 32, and the connecting plate 38 is fixedly mounted on the output end of the telescopic cylinder 35. The transmission joint 36 is rotatably connected to the outer wall of one side of the connecting plate 38, and the transmission joint 36 maintains a sliding connection with the output end of the winding motor 31. The connecting plate 38 can be driven to maintain reciprocating motion through the telescopic cylinder 35. Since the transmission joint 36 is rotatably connected to the connecting plate 38, the transmission joint 36 can still maintain rotation during the movement of the connecting plate 38.

[0033] During use, when the workpiece to be tested is located on the fixed plate 12, the telescopic cylinder 35 drives the connecting plate 38 to move away from the linkage joint 37, thereby separating the linkage joint 37 and the transmission joint 36. Then, under the action of gravity, the impact head drives the connecting chain to unwind the winding rod 32, and finally causes the impact head to hit the workpiece to be tested, so as to simulate a real collision and test the collision performance of the workpiece to be tested.

[0034] After the collision is completed, the telescopic cylinder 35 can be used to drive the connecting plate 38 to move toward the linkage joint 37, so that the linkage joint 37 and the transmission joint 36 remain plugged in, thereby maintaining the transmission connection between the winding rod 32 and the winding motor 31. The winding rod 32 can be driven by the winding motor 31 to keep rotating, thereby winding the connecting chain and lifting the impact head.

[0035] The elastic coefficient of the decompression spring mentioned in this article meets the technical requirements of the technical solution of the utility model.

[0036] Those skilled in the art will appreciate that other similar connection methods can also implement the present invention, such as welding, bonding, or screwing.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
