[0030] The following description is used to disclose the utility model so that those skilled in the art can realize the utility model. The preferred embodiments in the following description are only as examples, and other obvious modifications can be thought of by those skilled in the art.

[0031] Reference Figures 1-5As shown, a kind of static pressure strength test bench for automobile metal parts detection, including base 1, the upper surface of base 1 is fixedly connected with multiple support columns 6, the upper end of multiple support columns 6 is fixedly connected with pressing plate 2, the inside of pressing plate 2 and base 1 is correspondingly provided with extrusion mechanism 3, the opposite end of two extrusion mechanisms 3 is provided with adjusting mechanism 4, the upper surface of base 1 is provided with two symmetrical movement assemblies 5, the opposite side of two movement assemblies 5 is provided with clamping mechanism 7, and clamping mechanism 7 is symmetrically distributed;Wherein, movement assembly 5 includes slide rod 501 and installation slot 508, installation slot 508 is opened in the upper end of base 1, the both ends of slide rod 501 are arranged in the inside of installation slot 508 and are fixedly connected to the inner wall of base 1, the surface of slide rod 501 is slidably connected with connecting block 502, and connecting block 502 is arranged in the inside of installation slot 508;Clamping mechanism 7 includes mounting block 702 and electric push rod 705, one end of electric push rod 705 is fixedly installed in the inside of mounting block 702, the left side of mounting block 702 is fixedly connected with two symmetrical side plates 703, the output end of electric push rod 705 is fixedly connected with pull block 706, and the both ends of pull block 706 are slidably connected to the inner side of two side plates 703;The inner side of the outer wall of two side plates 703 is rotatably connected with limiting column 707, and the surface of side plate 703 is rotatably connected with two center-symmetric clamping plates 704;The inner side right part of two clamping plates 704 is respectively arranged on the upper and lower sides of pull block 706, and the outer wall of two clamping plates 704 is arranged in the inner side of two side plates 703 The inner side right part of two clamping plates 704 is respectively arranged on the upper and lower sides of pull block 706, and the outer wall of two clamping plates 704 is arranged in the inner side of two side plates 703;The right side of mounting block 702 is screw-connected in the inside of buffer block 506 by second adjusting bolt 701, and the right side of buffer block 506 is fixedly connected with two symmetrically arranged limiting rods 505.

[0032] Specifically, the base 1 supports and fixes various mechanisms, the plurality of support columns 6 fix the pressing plate 2 above the base 1 and provide a support point for testing, the extrusion mechanism 3 installed on the base 1 and the pressing plate 2 provides a pressure source for testing, and the hydraulic pump connected to the extrusion mechanism 3 provides a power source for the extrusion mechanism 3, which facilitates testing of workpieces. By replacing different molds, different models of workpieces can be tested. The two symmetrical moving assemblies 5 installed on the upper side of the base 1 drive the clamping mechanism 7 to move, thereby adjusting the position of the clamping mechanism 7 to adapt to workpieces of different shapes. Each moving assembly 5 and clamping mechanism 7 can be freely adjusted to adapt to irregular workpieces. The mounting block 702 in the clamping mechanism 7 is connected to the moving assembly 5 through the second adjusting bolt 701. By adjusting the tightness of the second adjusting bolt 701, the rotation of the clamping mechanism 7 can be controlled to maintain the original angle without external intervention, thereby achieving random adjustment and fixation of the angle of the clamping mechanism 7 in the horizontal direction. The electric push rod 705 inside the mounting block 702 drives the pull block 706 to move inside the two side plates 703. The trapezoidal pull block 706 pushes the two clamping plates 704 to move up and down towards one end of the mounting block 702. At the same time, the limiting column 707 limits the two clamping plates 704 so that the other end can only move towards the middle, thereby clamping the workpiece. By adjusting the angle of the mounting block 702 in the vertical direction, the mounting block 702 can adapt to workpieces of different angles and types.

[0033] Referring to Figures 1-4 As shown in the figure, the ends of the two limiting rods 505 away from the buffer block 506 are connected with a fixed block 504, and the fixed block 504 is installed with a first air cylinder 503 on one side;

[0034] Specifically, the movement direction of the limiting rod 505 is limited by the fixed block 504, ensuring that the connected buffer block 506 can only move horizontally in the fixed block 504, and thus when the first air cylinder 503 pushes the buffer block 506, the movement trajectory can be limited. At the same time, the first adjusting bolt 507 connects the fixed block 504 and the connecting block 502, and by adjusting the tightness of the connecting block 502, the connecting block 502 can only rotate under external intervention, thereby controlling the movement of the fixed block 504 and its angle in the horizontal direction, preventing unnecessary rotation of the connecting block 502.

[0035] Referring to Figures 1-2 As shown in the figure, the extrusion mechanism 3 includes a screw 301 and a hydraulic cylinder 302, and the two hydraulic cylinders 302 are connected to the opposite sides of the base 1 and the pressing plate 2 through the screw 301 respectively;

[0036] Specifically, the screw 301 fixes the hydraulic cylinder 302 on the upper side of the base 1 and the lower side of the pressing plate 2 respectively, and the output ends of the two hydraulic cylinders 302 are opposite. When detecting a workpiece, a single pressure end or two opposite pressure ends can be selected.

[0037] Referring to Figures 1-2 As shown, the adjusting mechanism 4 includes a mounting plate 401 connected with the hydraulic cylinder 302, and a sliding block 402 provided inside the mounting plate 401;

[0038] Specifically, the hydraulic cylinder 302 drives the adjusting mechanism 4 to move, so as to press the workpiece and test the static pressure strength of the workpiece. The sliding groove 403 inside the mounting plate 401 limits the position of the sliding block 402, so that the sliding block 402 will not fall off during use. The sliding groove 403 also facilitates replacement of the sliding block 402 and the mold mounted thereon, so that different tests can be performed on different workpieces.

[0039] Working principle: during use, the sliding block 402 inside the mounting plate 401 is taken out, and different molds are replaced according to needs, so that the test result can be more accurate. The sliding block 402 is inserted into the inside of the sliding groove 403 and adjusted to the required position;

[0040] When testing the workpiece, the electric push rod 705 inside the mounting block 702 is started, the pull block 706 is driven by the electric push rod 705 to shrink towards the mounting block 702, so as to drive the rear end of the two clamping plates 704 to move outward, the clamping plates 704 are limited by the limiting column 707 in the middle of the two clamping plates 704, so that the movement of one end of the clamping plate 704 drives the other end of the clamping plate 704 to move towards the middle, so as to fix the workpiece. By controlling the tightness of the second adjusting bolt 701, the angle of the clamping mechanism 7 can be controlled conveniently. The angle of the clamping mechanism 7 is fixed at a specific position without external force interference. When external force is applied, the clamping mechanism 7 can rotate in the vertical direction around the second adjusting bolt 701, so as to adjust the angle of clamping according to the shape of the workpiece,

[0041] The position of the clamping mechanism 7 is adjusted and limited by the moving assembly 5 fixed inside the base 1. The connecting block 502 moves on the slide rod 501. The angle of the fixed block 504 in the horizontal direction can be controlled by the tightness of the first adjusting bolt 507, so as to adjust the direction of the clamping mechanism 7 according to the shape of the workpiece. At the same time, the distance between the clamping mechanism 7 and the adjusting mechanism 4 is controlled by the first cylinder 503 on the fixed block 504, so as to adjust the position of the clamping mechanism 7 according to the shape of the workpiece. At the same time, the clamping mechanism 7 is limited by the two limiting rods 505 inside the fixed block 504, and the first cylinder 503 is protected;

[0042] When the workpiece is detected, a single or two hydraulic cylinders 302 can be selected for experiment, when a single one is selected, the hydraulic cylinder 302 on the pressing plate 2 is used as a pressure source, when two ones are selected, the hydraulic cylinders 302 inside the base 1 and the pressing plate 2 apply pressure at the same time, the hydraulic cylinders 302 are operated through an external hydraulic pump, the two adjusting mechanisms 4 are pushed to the middle through the hydraulic cylinders 302, so that the static pressure strength of the workpiece can be tested through the extrusion die installed on the sliding block 402.

[0043] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by the person skilled in the art that the utility model is not limited by the above-mentioned embodiments, the above-mentioned embodiments and the description in the specification are only the principles of the utility model, various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed for protection.
