Technical Field

[0001] This utility model relates to the field of pressure detection technology, and in particular to a novel automatic pressure detection device for workpieces. Background Technology

[0002] The workpiece automatic inspection pressure device is a device designed for automated pressure testing and evaluation of workpieces.

[0003] Chinese Patent Publication No. CN217638362U, published on October 21, 2022, discloses a novel pressure detection device, including a bracket and a clamping component for fixing a workpiece. The clamping component includes a fixed frame on the top of the bracket, sliding grooves on one side of the bracket and located on both sides of the fixed frame, a bidirectional screw on one side of the sliding groove, a motor at one end of the bidirectional screw, a sliding block on one side of the sliding groove and located outside the bidirectional screw, a fixed plate on one side of the sliding block, two springs on one side of the fixed plate, a clamping plate on one side of the springs, an anti-slip pad on one side of the clamping plate, and a pressing component for pressure detection of the workpiece. The bidirectional screw passes through the sliding block and is screwed to it, and the sliding block is slidably connected to the sliding groove.

[0004] Existing automatic workpiece detection pressure devices, such as those described above, achieve workpiece positioning by driving two sets of clamping plates to move relative to each other through a drive assembly. In practice, the workpiece can be placed stably on the base. However, some workpieces have irregular outer contours, and the two sets of clamping plates moving relative to each other often cannot achieve stable positioning of the workpiece. Therefore, there is an urgent need to propose a new type of automatic workpiece detection pressure device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a novel automatic pressure detection device for workpieces in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel automatic pressure detection device for workpieces includes a base, a pressure block, a pressure sensor, and a vacuum adsorption assembly. The vacuum adsorption assembly includes a vacuum suction cup and a vacuum generator fixedly connected to the bottom of the base. The vacuum generator and the vacuum suction cup are connected via a bellows. A pushing assembly for driving the vacuum suction cup to move longitudinally is integrated on the inner surface of the top of the base. A pushing component is fixedly connected to the top of the base via a top frame. A support is fixedly connected to the output end of the pushing component. The pressure block and the pressure sensor are respectively arranged on both sides of the horizontal end of the support.

[0008] Preferably, an upper seat is fixedly connected to the top of the base, a telescopic member is fixedly connected to the outer wall of the upper seat, and a push block is fixedly connected to the output end of the telescopic member.

[0009] Preferably, a connecting frame is fixedly connected to the rear end face of the base, and the top of the horizontal end of the connecting frame is fixedly connected to the vacuum generator.

[0010] Preferably, the connecting frame and the upper seat are connected in series by a connecting plate, and the connecting plate is fixedly connected to the rear end face of the base by screws.

[0011] Preferably, a vertical plate is fixedly connected to the top of the support, and the outer wall of the vertical plate is slidably connected to the inner wall of the top of the top frame.

[0012] Preferably, the pushing assembly includes a driving component and a light rod that are fixedly connected to the bottom of the base via two sets of base blocks. The output end of the driving component is fixedly connected to a transmission rod. The outer wall of the transmission rod is screwed onto a movable seat that slides with the light rod, and the movable seat is fixedly connected to a vacuum suction cup.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the driving component drives the transmission rod to rotate. The transmission rod provides a pushing force to the moving seat by engaging with the inner surface of the moving seat. The moving seat drives the vacuum suction cup to move longitudinally along the guide rod until the vacuum suction cup moves to a suitable longitudinal position. During this process, the bellows expands and contracts synchronously to ensure the communication between the vacuum generator and the vacuum suction cup. The workpiece is placed on the base and placed above the vacuum. The vacuum generator works, and the vacuum suction cup applies negative pressure to the workpiece to achieve positioning. Finally, the pushing component pushes the support. The pressure of the workpiece is detected by the pressure sensor in conjunction with the pressure block. The vacuum suction method is not affected by the external contour of the workpiece, and the longitudinal position of the vacuum suction cup is adjustable to adapt to different positioning requirements.

[0015] 2. In this application, after the workpiece completes the pressure test, the vacuum adsorption state is released, and the telescopic component will push the workpiece to the front side of the top of the base through the push block, so as to avoid the operator taking out the workpiece from under the support, and further improve the safety of the new workpiece automatic pressure detection device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A novel automatic workpiece pressure detection device includes a base 1, a pressure block 4, a pressure sensor 5, and a vacuum adsorption assembly. The vacuum adsorption assembly includes a vacuum suction cup 8 and a vacuum generator 13 fixedly connected to the bottom of the base 1. The vacuum generator 13 and the vacuum suction cup 8 are connected by a bellows 15. The inner surface of the top of the base 1 is integrated with a pushing assembly for pushing the vacuum suction cup 8 to move longitudinally. The top of the base 1 is fixedly connected to a pushing component 7 through a top frame 2. The output end of the pushing component 7 is fixedly connected to a support 3. The pressure block 4 and the pressure sensor 5 are respectively arranged on both sides of the horizontal end of the support 3.

[0025] The driving component drives the transmission rod 11 to rotate. The transmission rod 11 provides a pushing force to the moving seat 12 by screwing it onto the inner wall of the moving seat 12. The moving seat 12 drives the vacuum suction cup 8 to move longitudinally along the light rod 10 until the vacuum suction cup 8 moves to a suitable longitudinal position. During this process, the bellows 15 extends and retracts synchronously to ensure the communication between the vacuum generator 13 and the vacuum suction cup 8. The workpiece is placed on the base 1 and positioned above the vacuum suction cup 8. The vacuum generator 13 works, and the vacuum suction cup 8 applies negative pressure to the workpiece to achieve positioning. Finally, the pushing component 7 pushes the support 3. The pressure sensor 5 works in conjunction with the pressure block 4 to detect the pressure of the workpiece. The vacuum suction method is not affected by the external contour of the workpiece, and the longitudinal position of the vacuum suction cup 8 is adjustable to adapt to different positioning requirements.

[0026] It should be noted that the vacuum generator 13 and the vacuum suction cup 8 here both adopt existing technology. The open end of the vacuum suction cup 8 is integrated with a telescopic mechanism that can be vertically extended and retracted, which facilitates the connection between the vacuum suction cup 8 and the outer wall of the workpiece without affecting the downward pressure of the workpiece.

[0027] Specifically, such as Figure 2 and Figure 4 As shown, an upper seat 16 is fixedly connected to the top of the base 1, and a telescopic component 17 is fixedly connected to the outer wall of the upper seat 16. A push block 18 is fixedly connected to the output end of the telescopic component 17. After the workpiece completes the pressure test, the vacuum adsorption state is released, and the telescopic component 17 will push the workpiece to the front side of the top of the base 1 through the push block 18, so as to avoid the operator from taking out the workpiece from under the support 3, which further improves the safety of the new workpiece automatic pressure detection device. A connecting frame 14 is fixedly connected to the rear end face of the base 1. The top of the horizontal end of the connecting frame 14 is fixedly connected to the vacuum generator 13 to ensure the stability of the position of the vacuum generator 13. The connecting frame 14 and the upper seat 16 are connected in series by a connecting plate, and the connecting plate is fixedly connected to the rear end face of the base 1 by screws, so as to ensure the ease of disassembly and assembly of the vacuum generator 13 and the telescopic component 17.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, a vertical plate 6 is fixedly connected to the top of the support 3. The outer wall of the vertical plate 6 is slidably connected to the inner wall of the top of the top frame 2 to further ensure the stability of the vertical movement of the support 3. The pushing component includes a driving component and a light rod 10 fixedly connected to the bottom of the base 1 through two sets of bottom blocks 9. A transmission rod 11 is fixedly connected to the output end of the driving component. A movable seat 12 that slides with the light rod 10 is screwed onto the outer wall of the transmission rod 11. The movable seat 12 is fixedly connected to the vacuum suction cup 8. The driving component drives the transmission rod 11 to rotate. The transmission rod 11 provides a pushing force to the movable seat 12 by screwing onto the inner wall of the movable seat 12. The movable seat 12 drives the vacuum suction cup 8 to move longitudinally along the light rod 10 until the vacuum suction cup 8 moves to a suitable longitudinal position.

[0029] Working principle: The driving component drives the transmission rod 11 to rotate. The transmission rod 11 provides a pushing force to the moving seat 12 by screwing it onto the inner wall of the moving seat 12. The moving seat 12 drives the vacuum suction cup 8 to move longitudinally along the guide rod 10 until the vacuum suction cup 8 moves to a suitable longitudinal position. During this process, the bellows 15 extends and retracts synchronously to ensure the communication between the vacuum generator 13 and the vacuum suction cup 8. The workpiece is placed on the base 1 and positioned above the vacuum suction cup 8. The vacuum generator 13 operates, and the vacuum suction cup 8 applies negative pressure to the workpiece to achieve positioning. Finally, the pushing component 7 pushes the support 3. The pressure sensor 5, in conjunction with the pressure block 4, detects the pressure of the workpiece. The vacuum suction method is unaffected by the external contour of the workpiece, and the longitudinal position of the vacuum suction cup 8 is adjustable to adapt to different positioning requirements. After the workpiece pressure detection is completed, the vacuum suction state is released, and the telescopic component 17 pushes the workpiece to the front of the top of the base 1 via the push block 18 to avoid the operator having to remove the workpiece from under the support 3, further improving the safety of the new automatic workpiece pressure detection device.
