Description

Technical Field

[0001] The present application belongs to the technical field of rivet processing, and specifically relates to a clamping device for a stainless steel rivet workpiece. Background Art

[0002] Blind rivets are also called blind rivets. Blind rivets are used for single-sided riveting, but they must be riveted with a special tool, a rivet gun. This type of rivet is particularly suitable for riveting occasions where ordinary rivets are inconvenient to use, so it is widely used in construction, automobiles, ships, aircraft, machinery, electrical appliances, furniture and other products. Among them, open-type flat round head blind rivets are the most widely used, and closed-type blind rivets are suitable for riveting occasions that require higher loads and certain sealing properties.

[0003] For example, patent number CN207386045U discloses a waterproof rivet processing machine, including a bottom plate, a frame is provided on the bottom plate, a driving motor is provided at the inner bottom of the frame, a driving shaft is provided at the upper part of the driving motor, the lower end of the driving shaft is installed at the upper part of the driving motor, a rotary drum is provided at the upper end of the driving shaft, and a magnetic seat is provided at the inner bottom position of the rotary drum; a flushing machine is provided on the bottom plate, a flushing pipe is provided at the side position of the frame, a flushing head is provided at the front end of the flushing pipe, the flushing head is installed above the rotary drum, the rear end of the flushing pipe is connected to the flushing machine through a pumping pipe, the upper end of the pumping pipe is connected to the rear end of the flushing pipe, the lower end of the pumping pipe is arranged in the flushing machine, a pumping pump is provided at the lower end of the pumping pipe, and the pumping pump is installed at the inner bottom of the flushing machine; a control switch is provided at the middle position of the pumping pipe. The utility model can flush the flushing liquid onto the surface of the waterproof rivet through the flushing head, so that the waterproof rivet can be flushed conveniently, which greatly improves the efficiency of the flushing operation.

[0004] In the process of realizing this application, it was found that the technology has the following problems. The device fixes the root of the waterproof rivet by magnetic attraction through a magnetic seat, and then pumps the flushing liquid into the flushing head through a flushing machine, and then uses the flushing head to flush the flushing liquid onto the surface of the waterproof rivet for processing and polishing. Since this design fixes the root of the rivet by magnetic attraction, it may become loose when facing the high-pressure flushing water flow, causing the flushing point to shift and affecting the processing quality. Furthermore, the upper part of the rivet lacks rear support when facing high-pressure flushing, which may cause the rivet to bend during flushing, affecting the matching of the product with the rivet gun when it is used later. Therefore, in order to solve this problem and optimize this design, a clamping device for stainless steel rivet workpieces is proposed. Utility Model Content

At this time, the rivet on the cartridge seat can be driven to rotate by the No. 1 motor to perform multi-directional flushing on the annular surface of the rivet. During the flushing process, the No. 3 motor is started to drive the No. 1 screw rod to rotate, thereby controlling the spray gun on the extension plate at the front end of the No. 1 slider to move up and down, so that the spray gun flushes the vertical position of the rivet in all directions. In this process, due to the action of the photoelectric sensor and the signal plate, when the signal plate moves up and down following the extension plate, the photoelectric sensor can control the No. 4 motor to drive the No. 2 screw rod to rotate according to the movement of the signal plate, thereby controlling the No. 2 slider to move up and down, so that the abutment rod at the left end of the electric push rod is always in a relative position with the spray gun to abut the rivet, so as to prevent the rivet from bending and deforming when impacted by high-pressure water, thereby effectively ensuring the morphological quality of the workpiece after flushing.

[0026] By setting the abutment rod 26, when the rivet is clamped and fixed by the cartridge seat 4, the electric push rod 25 is started to extend so that the abutment wheel at the left end of the abutment rod 26 is close to the right wall of the rivet. At this time, the flushing machine 3 is started to discharge high-pressure water through the pipeline to the spray gun 19 to flush the rivet. At this time, the rivet on the cartridge seat 4 can be driven to rotate by the No. 1 motor 6 to perform multi-directional flushing on the annular surface of the rivet. During the flushing process, the No. 3 motor 20 is started to drive the No. 1 screw rod 17 to rotate, thereby controlling the spray gun 19 on the extension plate 18 at the front end of the No. 1 slider 16 to move up and down, so that the spray gun 19 The nails are flushed in all directions in the vertical position.

[0027] The implementation principle of the embodiment of the present application is:

[0028] First, by setting the barrel seat 4, when it is necessary to fix the rivet for flushing and grinding, the end part of the rivet is first inserted into the barrel seat 4 from the top of the barrel seat 4. At this time, the No. 2 motor 10 is started to drive the threaded rod 9 to rotate, and then drive the rack 8 to move toward the direction close to the No. 2 motor 10. At this time, the rack 8 engages the gear ring 7 and rotates counterclockwise. Since the guide sleeve 11 guides and limits the clamping rod 12, and the convex rod 13 on the top of the clamping rod 12 is slidably installed in the arc bevel groove 14 opened on the gear ring 7, the counterclockwise rotation of the gear ring 7 can drive the arc bevel groove 14 to squeeze the convex rod 13 to drive the clamping rod 12 to the center point of the barrel seat 4, and then the end of the rivet inserted into the barrel seat 4 is clamped and fixed, so as to stabilize the rivet for subsequent flushing and prevent the rivet from being offset when it is impacted by high-pressure water.

[0029] Furthermore, by setting the abutment rod 26, when the rivet is clamped and fixed by the cartridge seat 4, the electric push rod 25 is started to extend so that the abutment wheel at the left end of the abutment rod 26 is close to the right wall of the rivet. At this time, the flushing machine 3 is started to discharge high-pressure water through the pipeline to the spray gun 19 to flush the rivet. At this time, the rivet on the cartridge seat 4 can be driven to rotate by the No. 1 motor 6 to perform multi-directional flushing on the annular surface of the rivet. During the flushing process, the No. 3 motor 20 is started to drive the No. 1 screw rod 17 to rotate, thereby controlling the spray gun 19 on the extension plate 18 at the front end of the No. 1 slider 16 to move up and down, so that the spray gun 19 The vertical position of the rivet is flushed in all directions. During this process, due to the action of the photoelectric sensor 27 and the signal plate 28, when the signal plate 28 moves up and down following the extension plate 18, the photoelectric sensor 27 can control the No. 4 motor 24 to drive the No. 2 screw rod 23 to rotate according to the movement of the signal plate 28, and then control the No. 2 slider 22 to move up and down, so that the abutment rod 26 at the left end of the electric push rod 25 is always in a relative position with the spray gun 19 to abut the rivet, so as to prevent the rivet from bending and deforming when impacted by high-pressure water, thereby effectively ensuring the morphological quality of the workpiece after flushing.
