Description

Technical Field

[0001] This utility model relates to the field of welding head grinding technology, specifically a stainless steel wire welding head grinding device. Background Technology

[0002] After welding, stainless steel wire often has burrs, oxide layers or uneven weld beads at the joint, which affect the product's strength, conductivity and aesthetics. Grinding is required to meet the requirements of surface finish, dimensional accuracy and subsequent processing.

[0003] Most existing grinding devices use motors to drive clamping plates, and the clamping force varies when clamping materials of different sizes, which may cause material deformation.

[0004] Chinese patent discloses a device for grinding welded ends of steel bars (authorization announcement number CN207548378U). This patented technology uses a hand crank to drive a lead screw to rotate, which in turn drives a slider to move on the lead screw. The slider then drives a connecting rod, which in turn pushes a push rod and an upper clamping plate to move, thereby achieving the purpose of clamping the steel bars.

[0005] However, it has certain drawbacks: it lacks an automatic rebar flipping mechanism, and the angle cannot be adjusted after clamping. It can only perform unidirectional grinding on one side of the surface, requiring repeated disassembly and adjustment or manual flipping, which leads to cumbersome operation, low efficiency, and easy grinding omissions. Utility Model Content

[0006] The purpose of this invention is to provide a stainless steel wire welding head grinding device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A stainless steel wire welding head grinding device includes a grinding table. Two shell bearings are symmetrically fixed to the upper surface of the grinding table in the left-right direction. A fixing tube is fixed inside each of the two shell bearings. A fixing bolt is threaded through one end of the upper and lower surfaces of the two fixing tubes. A fixing block is rotatably connected to one end of the fixing bolt located inside the fixing tube. A grinding mechanism is provided on the upper surface of the grinding table behind the two shell bearings.

[0009] The upper surface of the grinding table is provided with a flipping mechanism in front of the two shell bearings. The flipping mechanism includes a fixed plate, and a telescopic cylinder II is fixedly connected to the front surface of the fixed plate. The telescopic end of the telescopic cylinder II is provided with a flipping component.

[0010] As a further embodiment of this utility model: the grinding mechanism includes an L-shaped plate, a telescopic cylinder is fixedly connected to the upper surface of the L-shaped plate, a support plate is fixedly connected to the telescopic end of the telescopic cylinder, a motor is fixedly connected to the front end of the upper surface of the support plate, and a grinding disc is fixedly connected to the output end of the motor.

[0011] As a further embodiment of this utility model: the flipping component includes a C-shaped plate, and racks are fixedly connected to the rear ends of both the left and right sides of the C-shaped plate, with gears meshing at the lower ends of the racks.

[0012] As a further improvement of this utility model, the lower end of the fixing plate is fixed to the upper surface of the grinding table.

[0013] As a further improvement of this utility model, the lower end of the L-shaped plate is fixed to the upper surface of the grinding table.

[0014] As a further embodiment of this utility model: the telescopic end of the telescopic cylinder two is fixed to the front surface of the C-shaped plate, and the two gears are respectively fixed to the outside of the opposite ends of the left and right fixed tubes.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes an optimized flipping mechanism, employing a rack and pinion meshing transmission combined with a reciprocating telescopic drive, to achieve automated forward and reverse rotation of the stainless steel wire welding head. During the grinding process, the wire angle can be dynamically adjusted to ensure the grinding disc evenly covers the circumferential surface of the weld, completely eliminating grinding blind spots caused by manual flipping. Simultaneously, the coordinated control of reciprocating rotation and grinding motion significantly improves work efficiency, reduces labor intensity, and ensures weld surface consistency and processing accuracy, making it particularly suitable for processing wire welding heads with complex shapes or high precision requirements.

Detailed Implementation

[0022] Please see Figures 1-3 In this embodiment of the present invention, a stainless steel wire welding head grinding device includes a grinding table 1. Two shell bearings 2 are symmetrically fixed to the upper surface of the grinding table 1 in the left and right directions. A fixing tube 3 is fixed to the inside of each of the two shell bearings 2. A fixing bolt 4 is threaded through the upper and lower surfaces of the two fixing tubes 3. A fixing block 5 is rotatably connected to the end of the fixing bolt 4 located inside the fixing tube 3. A grinding mechanism 6 is provided on the upper surface of the grinding table 1 behind the two shell bearings 2. The grinding mechanism 6 includes an L-shaped plate 7. The lower end of the L-shaped plate 7 is fixed to the upper surface of the grinding table 1. A telescopic cylinder 8 is fixed to the upper surface of the L-shaped plate 7. A support plate 9 is fixed to the telescopic end of the telescopic cylinder 8. A motor 10 is fixed to the front end of the upper surface of the support plate 9. A grinding disc 11 is fixed to the output end of the motor 10.

[0023] The fixed tube 3 is fixed in the inner ring of the shell bearing 2, so the two are in a state of mutual rotation;

[0024] The stainless steel wire is located in the left and right parts of the welding head, respectively, and is passed through the two fixed tubes 3 on the left and right sides, and is located between the two fixed blocks 5 on the upper and lower sides. Rotating the fixing bolt 4 can drive the fixing block 5 to clamp the stainless steel wire.

[0025] Fixing block 5 is an arc-shaped block used to fit the arc-shaped surface of the stainless steel wire;

[0026] The telescopic cylinder 18 is preferably a servo electric cylinder;

[0027] After the stainless steel wire is fixed, its welding head is located directly above the grinding disc 11. After the telescopic cylinder 8 extends, the grinding disc 11 fits perfectly against the stainless steel wire.

[0028] exist Figure 1 , Figure 2 and Figure 4In the middle: The upper surface of the grinding table 1 is located in front of the two shell bearings 2 and a flipping mechanism 12 is provided. The flipping mechanism 12 includes a fixed plate 13. The lower end of the fixed plate 13 is fixed to the upper surface of the grinding table 1. The front surface of the fixed plate 13 is fixed to a telescopic cylinder 14. The telescopic end of the telescopic cylinder 14 is provided with a flipping component 15. The flipping component 15 includes a C-shaped plate 16. The telescopic end of the telescopic cylinder 14 is fixed to the front surface of the C-shaped plate 16. The rear ends of the left and right sides of the C-shaped plate 16 are both fixed to racks 17. The lower end of the racks 17 is meshed with gears 18. The two gears 18 are respectively fixed to the outside of the opposite ends of the left and right fixed tubes 3.

[0029] The telescopic cylinder 14 is either a pneumatic cylinder or an electric cylinder, and its initial state is the extended state.

[0030] C-shaped plate 16 drives rack 17 to move back and forth, causing gear 18 to continuously rotate in both directions, which in turn drives stainless steel wire to rotate continuously through fixed tube 3, making it easier for grinding mechanism 6 to fully grind the weld head.

[0031] The stroke of telescopic cylinder 14 and the length of rack 17 are both long enough to ensure that the stainless steel wire can rotate at least 360° in both forward and reverse directions.

[0032] The working principle of this utility model is as follows: First, the left and right sections of the stainless steel wire welding head are respectively inserted into the left and right fixed tubes 3. By rotating the two side fixing bolts 4, the arc-shaped fixing blocks 5 are moved to achieve stable clamping of the wire. The motor 10 is started to drive the grinding disc 11 to rotate at high speed. At the same time, the telescopic cylinder 1 8 pushes the support plate 9 and the grinding disc 11 to move down, so that the grinding disc 11 accurately presses against the surface of the welding head for grinding. During the grinding process, the telescopic cylinder 2 14 retracts, driving the C-shaped plate 16 to move forward, so that the rack 17 and the gear 18 mesh. The combined drive gear 18 rotates forward, which in turn drives the fixed tube 3 and the clamped wire to rotate clockwise through the shell bearing 2; when the telescopic cylinder 2 14 extends, the C-shaped plate 16 moves backward, causing the rack 17 to mesh with the gear 18 in the opposite direction, driving the wire to rotate counterclockwise. Through the reciprocating motion of the telescopic cylinder 2 14, the rack 17 and the gear 18 continuously mesh and transmit power, realizing the periodic rotation of the wire welding head. Combined with the continuous grinding of the grinding disc 11, it ensures that the circumferential surface of the welding head is uniformly ground, eliminating grinding dead angles and improving processing efficiency and consistency.
