Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile manufacturing, in particular to a compression performance testing device for manufacturing metal structure aluminum profiles. Background Art

[0002] After the metal structure is produced and processed, it needs to be subjected to various types of tests to ensure the stability of the metal structure during subsequent use. Since the compressive resistance of the aluminum profile itself during use determines the safety of the metal structure during use, it is necessary to use a compressive resistance testing device to test the compressive resistance of the metal structure.

[0003] In the prior art, the Chinese patent with the authorization announcement number CN217638402U discloses a compressive performance test device for manufacturing metal structure aluminum profiles, including a test device body, a test chamber is provided on the left side of the front of the test device body, a test bench is provided inside the test chamber, an adjustment mechanism is provided on the upper end of the test bench, a fixing mechanism is provided on the outside of the adjustment mechanism, a control module is provided on the front of the test bench, a glass door is provided on the left side of the front of the test device body, and a machine door is provided in the machine room on the right side of the front of the test device body. A mounting groove is provided at the lower end of the mounting block, and a sliding block is provided for sliding in the mounting groove. The second screw is rotated and extended by the turning handle, so that the lower end of the second screw is connected to the sliding block for rotation and displacement, and the sliding block slides downward at the same time. The tube body can be conveniently fixed by the V-groove at the lower end of the sliding block, thereby eliminating the need for manual assistance in fixing the tube body for testing, thereby greatly improving the test efficiency.

[0004] The above-mentioned mechanism fixes the tube body by utilizing the mutual cooperation of the limit groove and the shift block. However, in actual use, due to the different sizes of different aluminum profiles, it is not convenient to limit aluminum profiles of different sizes during the fixing process, which affects the effect of subsequent compression testing. Utility Model Content

[0005] The purpose of the present utility model is to provide a compressive performance testing device for the manufacture of metal structure aluminum profiles, so as to solve the problem raised in the above background technology that due to the different sizes of different aluminum profiles, it is inconvenient to limit the aluminum profiles of different sizes during the fixation process, which affects the effect of subsequent compressive resistance testing.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a compressive performance testing device for use in the manufacture of metal structure aluminum profiles, comprising a test box, a pneumatic telescopic rod being bolted to the top end of the test box, a pressure plate being bolted to the output end of the pneumatic telescopic rod, and a workbench being provided at the middle position of the bottom end of the test box;

[0007] A drive motor is mounted on one end of the outer side of the test box via a coupling. The output end of the drive motor extends into the interior of the test box and is provided with a clamping mechanism for fixing the aluminum profile. The clamping mechanism includes a bidirectional threaded rod, and the bidirectional threaded rod is fixedly connected to one side of the output end of the drive motor. The outer side of the bidirectional threaded rod is threadedly connected to a movable block, and the top end of the movable block is fixedly connected to a clamping plate.

[0008] One side of the test box is fixedly connected to a mounting frame, and one side of the mounting frame is provided with a debris cleaning mechanism for cleaning the surface of the workbench.

[0009] Furthermore, the front cross section of the clamping plate is in a "C" shape, and the clamping plate is symmetrical about the vertical center axis of the test box.

[0010] Furthermore, a slider is fixedly connected to the bottom of the movable block, and both ends of the bottom of the test box are provided with sliding grooves matching the slider, and the movable block and the test box are slidably connected through the slider and the sliding groove to form a sliding structure.

[0011] Furthermore, an anti-skid pad is fixedly connected to the inner side of the clamping plate, and the anti-skid pads are distributed inside the clamping plate at equal intervals.

[0012] Furthermore, the cross section of the anti-slip pad is semicircular, and the length of the anti-slip pad is equal to the width of the clamping plate.

[0013] Furthermore, the debris cleaning mechanism includes an airbag, and the airbag is fixedly connected to one side of the mounting bracket, one side of the airbag is fixedly connected to a movable plate, and the movable plate and the mounting bracket are slidably connected, one end of the mounting bracket is rotatably connected to a cam, and the cam is connected to one side of the bidirectional threaded rod through a pulley, one side of the airbag is fixedly connected to a nozzle, and one side of the nozzle extends to the interior of the test box, the nozzle is arranged above the workbench, and a chip groove is opened on one side of the test box.

[0014] Furthermore, a return spring is fixedly connected to one side of the mounting frame, and an elastic structure is formed between the mounting frame and the movable plate through the return spring:

[0015] 1. The output end of the drive motor drives the bidirectional threaded rod to rotate, which in turn drives the movable block to move to one side, thereby causing the clamping plate at the top of the movable block to move toward the center of the test chamber. This allows the clamping plate to fix the aluminum profile placed on the workbench on the position, preventing the aluminum profile from shifting due to pressure during the compression test.

[0016] Furthermore, the movable block can slide inside the slide groove through the slider below when moving, and the slider can be used to fix the angle of the movable block, thereby preventing the movable block from angular deviation during the movement driven by the bidirectional threaded rod;

[0017] Furthermore, the cross section of the clamping plate is C-shaped, so that the inner side of the clamping plate can be attached to the side of aluminum profiles of different shapes and clamped to limit the position. At the same time, the anti-slip pad on the inner side of the clamping plate can increase the friction between the clamping plate and the aluminum profile when they are attached, so that the aluminum profile as a whole can be clamped more stably.

[0018] 2. When the bidirectional threaded rod is driven by the driving motor to rotate, the cam is driven to rotate through the pulley. The continuous rotation of the cam squeezes the movable plate, so that the airbag is pushed and squeezed by the movable plate and the internal gas is ejected through the nozzle. The gas ejected from the nozzle cleans the surface of the workbench, reduces the residual debris on the workbench surface, and avoids shaking of the aluminum profile during inspection;

[0019] Furthermore, when the airbag is squeezed by the movable plate, when the cam rotates to different angles, the elastic force of the reset spring can drive the movable plate to reset its position, so that the inside of the airbag can inhale gas through the nozzle, thereby keeping the airbag filled with gas, which is convenient for repeated cleaning of the surface of the workbench.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 7 The technical solution shown is to solve the problem that it is inconvenient to limit the position of aluminum profiles of different sizes during the fixing process due to the different sizes of different aluminum profiles: the compression performance testing device for metal structure aluminum profile manufacturing discloses a clamping mechanism, including a test box 1, a pneumatic telescopic rod 2 is installed on the top of the test box 1 through bolts, and a pressing plate 3 is installed on the output end of the pneumatic telescopic rod 2 through bolts, a workbench 4 is provided at the middle position of the bottom end of the test box 1, a drive motor 6 is installed on one end of the outer side of the test box 1 through a coupling, and the output end of the drive motor 6 extends to the interior of the test box 1 and is provided with The clamping mechanism for fixing the aluminum profile includes a bidirectional threaded rod 7, and the bidirectional threaded rod 7 is fixedly connected to one side of the output end of the drive motor 6. The outer side of the bidirectional threaded rod 7 is threadedly connected to a movable block 8, and the top of the movable block 8 is fixedly connected to a clamping plate 9. The front cross-section of the clamping plate 9 is "C"-shaped, and the clamping plate 9 is symmetrical about the vertical center axis of the test box 1. The bottom end of the movable block 8 is fixedly connected to a slider 11, and both ends of the bottom end of the test box 1 are provided with a slide groove 12 matching the slider 11, and the movable block 8 and the test box 1 are slidably connected through the slider 11 and the slide groove 12 to form a sliding structure.

[0031] In this example, the aluminum profile to be inspected is placed on the surface of the workbench 4, and the output end of the pneumatic telescopic rod 2 is used to push the pressing plate 3 downward, so that the bottom end of the pressing plate 3 presses the aluminum profile. The workbench 4 can disperse the pressure applied by the pressing plate 3 on the aluminum profile, thereby making the aluminum profile more stable during inspection.

[0032] The output end of the driving motor 6 drives the bidirectional threaded rod 7 to rotate, so that the bidirectional threaded rod 7 can drive the movable block 8 to move to one side, and then the clamping plate 9 at the top of the movable block 8 moves toward the center of the test box 1, so that the clamping plate 9 can fix the position of the aluminum profile placed on the workbench 4, avoiding the position displacement of the aluminum profile due to pressure during the compression test.

[0033] Example 2:

[0034] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The technical solution shown is to solve the problem of unstable clamping of aluminum profiles when clamping aluminum profiles: the compressive performance testing device for manufacturing metal structure aluminum profiles discloses an anti-slip pad 10, and the anti-slip pad 10 is fixedly connected to the inner side of the clamping plate 9, and the anti-slip pads 10 are evenly spaced inside the clamping plate 9. The cross-section of the anti-slip pad 10 is semicircular, and the length of the anti-slip pad 10 is equal to the width of the clamping plate 9.

[0035] In this example, the cross-section of the clamping plate 9 is C-shaped, so that the inner side of the clamping plate 9 can be fitted with the side of aluminum profiles of different shapes and clamped and limited. At the same time, the anti-slip pad 10 on the inner side of the clamping plate 9 can increase the friction between the clamping plate 9 and the aluminum profile when they are fitted, so that the aluminum profile as a whole can be clamped more stably.

[0036] Example 3:

[0037] like Figure 1 、 Figure 5 and Figure 6 The technical solution shown is to solve the problem that debris is easily generated during compression testing: the compression performance testing device for metal structure aluminum profile manufacturing discloses a debris cleaning mechanism. A mounting bracket 13 is fixedly connected to one side of the test box 1, and a debris cleaning mechanism for cleaning the surface of the workbench 4 is provided on one side of the mounting bracket 13. The debris cleaning mechanism includes an airbag 14, and the airbag 14 is fixedly connected to one side of the mounting bracket 13. A movable plate 16 is fixedly connected to one side of the airbag 14, and the movable plate 16 and the mounting bracket 13 are slidably connected. One end of the mounting bracket 13 is rotatably connected to a cam 17, and the cam 17 is connected to one side of the bidirectional threaded rod 7 through a pulley. A nozzle 18 is fixedly connected to one side of the airbag 14, and one side of the nozzle 18 extends into the interior of the test box 1. The nozzle 18 is arranged above the workbench 4. A chip discharge groove 5 is opened on one side of the test box 1. A reset spring 15 is fixedly connected to one side of the mounting bracket 13, and an elastic structure is formed between the mounting bracket 13 and the movable plate 16 through the reset spring 15.

[0038] In this example, when the bidirectional threaded rod 7 is driven by the driving motor 6 to rotate, the cam 17 is driven to rotate through the pulley. The continuous rotation of the cam 17 squeezes the movable plate 16, so that the airbag 14 is pushed and squeezed by the movable plate 16 and the internal gas is ejected through the nozzle 18. The gas ejected from the nozzle 18 cleans the surface of the workbench 4, reduces the residual debris on the surface of the workbench 4, and avoids shaking of the aluminum profile during inspection.

[0039] In the process of the airbag 14 being squeezed by the movable plate 16, when the cam 17 rotates to different angles, the elastic force of the return spring 15 can drive the movable plate 16 to reset its position, so that the inside of the airbag 14 can inhale gas through the nozzle 18, thereby keeping the airbag 14 filled with gas, which is convenient for repeated cleaning of the surface of the workbench 4.
