DETAILED DESCRIPTION

[0032] The application will be further described in detail below with reference to the drawings.

[0033] The present application embodiment discloses a pressing device for testing product performance, such as Figure 1 and Figure 2 As shown, it includes: a base plate 10 attached to the bearing surface of the workbench 1, an extension plate 2 is also attached to the bearing surface of the workbench 1, the extension plate 2 is fixed to the loading side of the base plate 10, and the thickness of the extension plate 2 is roughly the same as the thickness of the base plate 10, a movable plate 21 is slidably installed on the extension plate 2, and a columnar support platform 20 is installed on the movable plate 21, the support platform 20 is used to carry the workpiece to be processed, and at the same time, a power component is also installed on the extension plate 2, the power component is used to drive the movable plate 21 to slide. It should be noted that the extension plate 2 and the base plate 10 are both provided with relatively aligned slide grooves 12 for the movable plate 21 to slide, so that the movable plate 21 can also slide stably onto the base plate 10.

[0034] Among them, fixed rods are provided at the four corners of the base plate 10, a mounting frame 11 is installed on the fixed rods, and a pressing mechanism is provided on the mounting frame 11. The pressing mechanism of this embodiment is mainly composed of a driving device (hydraulic cylinder) and a pressure plate. Since it is relatively traditional, we will not go into details here. When the workpiece needs to be tested, it is only necessary to place the workpiece on the bearing surface of the support table 20, and use the power component to drive the movable plate 21 to move to the bottom of the pressing mechanism. At this time, the driving device can be turned on to drive the pressure plate of the pressing mechanism to perform a pressing test on the workpiece.

[0035] Taking into account the fact that the workpiece is prone to shaking, which may lead to inaccurate test data, in this embodiment, a limit assembly is provided on the support platform 20, and the limit assembly is used to limit the workpiece to improve its stability.

[0036] In this embodiment, the limiting assembly includes: a limiting groove 22 provided on the bearing surface of the support platform 20, the limiting groove 22 is a roughly circular groove, and a plurality of sliding holes 23 are provided on the inner wall of the circumference of the limiting groove 22, and a limiting rod 24 is slidingly arranged in the sliding hole 23. A driving component for driving the limiting rod 24 to slide in the sliding hole 23 is also provided on the support platform 20. When the workpiece is placed in the limiting groove 22, the driving component can be used to drive the limiting rod 24 so that the end of the limiting rod 24 abuts against the outside of the workpiece, thereby completing the limitation of the workpiece.

[0037] In the embodiment, the driving component comprises: an annular groove 25 arranged in the support table 20 and communicated with the sliding hole 23 away from one end of the limiting groove 22, an annular rod 26 is slidingly arranged in the annular groove 25, the annular rod 26 can slide in the annular groove 25, a plurality of protrusions 27 are fixed on the outer side of the annular rod 26 at a predetermined position, and the end of the limiting rod 24 away from the limiting groove 22 is provided with an inclined surface matched with the protrusions 27. Meanwhile, in order to make the inclined surface of the limiting rod 24 always abut against the protrusions 27, an elastic member is installed in the sliding hole 23. The elastic member in the embodiment can be a return spring. The return spring applies a force to the limiting rod 24 to slide away from the limiting groove 22. In addition, a driving member is arranged on the outer side of the support table 20. The driving member is used to drive the limiting rod 24 to slide towards the limiting groove 22.

[0038] The driving member comprises: a servo motor 3 installed on the outer side of the support table 20. The output shaft of the servo motor 3 is vertically arranged. A gear 31 is installed on the output shaft of the servo motor 3. An arc-shaped operation groove 28 is arranged on the outer side of the support table 20 near the gear 31. The operation groove 28 is communicated with the annular groove 25. An arc-shaped plate 29 is slidingly arranged on the outer wall of the support table 20. The arc-shaped plate 29 is matched in size with the operation groove 28 and can slide along the arc-shaped extension direction of the operation groove 28. The inner side of the arc-shaped plate 29 is fixed with the annular rod 26 through a connecting rod. The outer side of the arc-shaped plate 29 is provided with teeth meshed with the gear 31.

[0039] When the workpiece to be processed is placed in the limiting groove 22, the servo motor 3 can be started to drive the gear 31 to rotate. When the gear 31 rotates, the arc-shaped plate 29 is driven to slide through the teeth meshed with the gear 31. The arc-shaped plate 29 drives the annular rod 26 to slide in the annular groove 25 through the connecting rod. During the sliding process of the annular rod 26, the protrusions 27 abut against the inclined surface on the end of the limiting rod 24. The end of the limiting rod 24 slides towards the outer side of the workpiece. Until the plurality of limiting rods 24 abut against the outer circumferential side of the workpiece at the same time. Through this scheme, the workpiece can be conveniently limited to reduce the shaking during the workpiece testing process.

[0040] In order to increase the limiting effect of the limiting rod 24, a rubber block 240 is threadedly connected to the inner end of the limiting rod 24 near the limiting groove 22 in the embodiment. The rubber block 240 is matched with the outer contour of the workpiece to be processed. When the rubber block 240 is attached to the outer side of the workpiece, the contact area between the two can be increased to increase the friction. Meanwhile, a containing groove matched with the rubber block 240 is arranged on the inner wall of the limiting groove 22. When the return spring drives the limiting rod 24 to reset, the rubber block 240 can be accommodated in the containing groove to reduce the space occupation.

[0041] In order to reduce the idle time of workpiece testing and improve work efficiency, the moving plate 21 is slidably arranged on both sides of the extension plate 2 in the embodiment. The first sliding rail 41 is arranged on the moving plate 21, the extension direction of the first sliding rail 41 is perpendicular to the sliding direction of the moving plate 21, the spacer plate is arranged at a predetermined position of the base plate 10, the height of the spacer plate is consistent with the height of the moving plate 21, the second sliding rail 42 is arranged on the spacer plate, the end of the second sliding rail 42 is aligned with the end of the first sliding rail 41, and the driving mechanism is further arranged on both sides of the base plate 10 to facilitate the movement of the support table 20. When the end of the first sliding rail 41 is aligned with the end of the second sliding rail 42, the driving mechanism can drive the support table 20 to be converted between the first sliding rail 41 and the second sliding rail 42.

[0042] In the embodiment, the driving mechanism comprises the guide rail 43 mounted on the bearing surface of the workbench 1, the extension direction of the guide rail 43 is consistent with the extension direction of the first sliding rail 41, the sliding seat 44 is slidably arranged on the guide rail 43, and the air cylinder 45 is further mounted on the workbench 1 and used to drive the sliding seat 44 to slide.

[0043] As shown in Figure 1 and Figure 3 The mounting plate 5 is attached to the side of the sliding seat 44 close to the base plate 10, the extension rod 51 is mounted on the mounting plate 5, the extension rod 51 is parallel to the guide rail 43, the support rod 52 is slidably sleeved on the extension rod 51 and vertically arranged, the symmetrical sliding blocks 53 are slidably arranged on the side of the mounting plate 5 close to the extension rod 51, the cross rods 54 are hingedly connected to the sliding blocks 53, the rod bodies of the cross rods 54 are movably sleeved on the support rod 52, and the rod bodies of the two cross rods 54 are hingedly connected together.

[0044] In addition, the arc-shaped clamping plates 55 are mounted at the ends of the cross rods 54 away from the sliding blocks 53, the inner sides of the arc-shaped clamping plates 55 are matched with the outer contour of the support table 20, and the miniature air cylinders are further mounted on the mounting plate 5 and used to drive the symmetrical sliding blocks 53 to move close to or away from each other.

[0045] When the worker places the workpiece to be processed in the limiting groove 22, after the limiting assembly completes the limitation of the workpiece, the driving force assembly is started to drive the moving plate 21 to move to a predetermined position, so that the end of the first sliding rail 41 is aligned with the end of the second sliding rail 42. At this time, the air cylinder 45 is started to drive the sliding seat 44 to move until the arc-shaped clamping plates 55 are located on both sides of the support table 20, and then the miniature air cylinder is started to drive the symmetrical sliding blocks 53 to move close to each other to drive the arc-shaped clamping plates 55 to clamp the support table 20. In cooperation with the air cylinder 45, the support table 20 can be pushed to the predetermined position of the second sliding rail 42. When the workpiece is tested, the reverse operation can be performed. This scheme can not only ensure the stability of the support table 20, but also improve the testing efficiency of the workpiece, which is a win-win situation.

[0046] In order to adapt to more actual situations, increase the application range of the arc-shaped clamping plate 55, in the embodiment, a mounting block 56 symmetrical in up and down is arranged on the side of the arc-shaped clamping plate 55 connected with the cross rod 54, a rotating shaft 57 is inserted between the end of the cross rod 54 away from the mounting plate 5 and the mounting block 56, and the end of the rotating shaft 57 is threadedly connected with a limiting ring 58. When the angle of the arc-shaped clamping plate 55 needs to be adjusted, the limiting ring 58 can be rotated to release the limitation on the arc-shaped clamping plate 55, so that the arc-shaped clamping plate 55 can be conveniently adjusted in angle. After adjustment, the limiting ring 58 is reversely rotated.

[0047] It should be noted that in the embodiment, the power assembly can adopt a common electric push rod or a hydraulic cylinder. Since it is common, it will not be described here.

[0048] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application.
