Description

Technical Field

[0001] The invention relates to the technical field of welding jigs, in particular to a metal jig for rapid welding positioning. Background Art

[0002] In the patent application with application announcement number CN209465868U, it includes a base for supporting the operation of all components, a sleeve shaft that plays a supporting role, and finally a connecting shaft for supporting the operation of the jig. A first cross plywood is provided above the base, and a second cross plywood is provided above the base on one side of the first cross plywood. The upper ends of the first cross plywood and the second cross plywood are fitted with a fixed frame, and the inner periphery of the fixed frame is provided with a flexible cover cloth. A connecting hole is provided at the inner middle position of the first cross plywood, and the outer surface of the flexible cover cloth is connected to an elastic adjustment rod, and a connecting rod is inserted at the corner position of the inner part of the elastic adjustment rod, and the upper end face of the elastic adjustment rod is at the corner position. An inner hole is opened, an outer hole is opened at the corner position of the upper end face of the fixed frame, and a pull wire is inserted into the inner periphery of the outer hole, a storage tube is fixedly installed at the middle position of the upper end face of the flexible cover cloth, and a reel is fixedly installed at the middle position inside the storage tube, and an auxiliary cover cloth is wound around the outer surface of the reel. The advantages are: the metal plate edge sealing welding jig adopts a first cross plywood and a second cross plywood, which can cross-fix the edges and corners of the metal plate to improve the fixing effect of the jig, and through the mutual cooperation between the fixed outer frame and the flexible cover cloth and the elastic adjustment rod, the shielding area of ​​the cover cloth can be changed according to the specifications of the metal plate to avoid sparks generated during welding from injuring the operator, and the entire jig has a simple structure and is easy to operate.

[0003] In the above-mentioned patents and prior art, metal jigs for welding include a series of products such as clamps. During the welding operation, welding slag will splash outward and larger welding slag will drip downward. If the dripping welding slag and the splashing welding slag fall on the surface of the clamp, they will condense and fix. In the later stage, the accumulation of welding slag will affect the normal fixation of the material. After the welding slag condenses, it is relatively solid and can only be dropped by shoveling. Shoveling will damage the surface of the clamp and manual cleaning is time-consuming and labor-intensive. Replacing a new clamp is not worth the effort and affects the operation efficiency. Summary of the Invention

[0004] The problem to be solved by the present invention is that welding slag drips and adheres to the top of the clamp, causing the top of the clamp to be highly uneven, affecting the normal clamping of the material and making it very troublesome to clean.

[0005] To solve the above technical problems, the technical solution of the present invention is: a metal jig for rapid welding positioning, comprising a base, a protective structure provided on the top of the base, a fixed structure provided inside the base, the protective structure being able to be positioned by the fixed structure, and a scraper being slidably provided on the front side of the top of the base;

[0006] The protective structure includes heat-resistant paper, which is segmented, each of which is provided with a center mark, and each of which has a through slot at each of the four corners of the top of the heat-resistant paper. The heat-resistant paper is wrapped around the surface of a rotating shaft, and a rotating seat is provided on one side of the rotating shaft.

[0007] The interior of the base is provided with a cavity, and the fixing structure includes a limit spring, the bottom of the limit spring is fixedly connected to the bottom of the cavity, the top of the limit spring is provided with a spring plate, one side of the spring plate is provided with a bevel, the front and rear sides of the top of the spring plate are fixed with a support rod, both sides of the top of the support rod are rotatably provided with a fixing plate, the rotation connection between the fixing plate and the support rod is provided with a torque spring, the top and bottom of the inner wall of the cavity are rotatably provided with a control plate, the front side of the control plate passes through the base and extends to the outside of the base, the front side of the control plate is fixed with a push block, the rotation connection between the control plate and the cavity is provided with a torque spring, and both sides of the control plate are fixed with a pressing block;

[0008] The base is provided with an opposing screw rod for rotation inside, and a moving block is threadedly connected to the opposing screw rod. A clamping block is symmetrically provided on the top of the moving block. An opposing threaded rod is provided inside the moving block, and the clamping block is adapted to the opposing threaded rod. An adjusting block is provided on the front of the opposing threaded rod, and the adjusting block can control the movement of the clamping block. A moving groove is provided on the back of the clamping block, and a positioning spring is fixed inside the moving groove. A movable block is fixed on one side of the positioning spring, and a clamping plate is rotatably provided on one side of the movable block, and a roller is rotatably provided on one side of the clamping block.

[0009] Preferably, a groove is provided at the bottom of the back side of the base, one side of the rotating seat is rotatably connected to one side of the groove, a fixed seat is fixed on the other side of the groove, and a card slot is provided on the front side of the fixed seat, which is adapted to one side of the rotating shaft.

[0010] Preferably, slide grooves are provided on both sides of the top of the base, and knobs are provided on both sides of the base, and the knobs can control the rotation of the opposing screw rods.

[0011] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0012] (1) A protective structure is provided on the top of the base. The protective structure covers the surface of the base with heat-resistant paper during daily use. When the base is fixed with materials for welding, the welding slag and dripping generated will mostly fall on the surface of the heat-resistant paper. When the welding slag is too much and affects the normal clamping of the material, the heat-resistant paper of that section can be removed from the four positioning holes. After removal, the new heat-resistant paper is pulled out from the rotating shaft and re-covered on the surface of the base. In this way, the surface of the base can be kept clean by replacing the heat-resistant paper. The heating temperature of the heat-resistant paper is higher than the temperature of the welding slag, so the welding slag will not damage the heat-resistant paper. There is also a center mark on the top of the heat-resistant paper. The center mark allows the operator to quickly align the center position when the welding joint and the center position of the base are aligned, without wasting time looking for the center position.

[0013] (2) A fixed structure is provided inside the base. The fixed structure can control the two spring plates to move downward at the same time by moving the push block, so that the support rod drives the fixed plate to separate from the surface of the base. The four support rods cooperate with the positioning holes on the heat-resistant paper to achieve a good positioning effect on the heat-resistant paper, avoiding the heat-resistant paper from moving during use. The fixed plate is in an open state to fix the heat-resistant paper in the normal state. In the closed state, it will be closed due to the limit of the positioning hole, which is convenient for users to replace the heat-resistant paper. The operation is simple and convenient, and it can be used together with the heat-resistant paper to achieve the dual effects of positioning and fixing.

[0014] (3) The base is also equipped with a clamping block, which can rotate freely according to the size of the material to be clamped. After clamping, the clamping block can be moved in opposite directions by rotating the adjustment block to achieve four-sided fixed clamping on the left and right and front and back sides, making the material more stable during welding. The rollers on the clamping block allow the material to be moved back and forth for fixation even in the clamped state. The splint and the movable block can achieve flexible clamping and auxiliary material centering. Rigid clamping is mainly done on the left and right. BRIEF DESCRIPTION OF THE DRAWINGS

The heat-resistant paper 102 is wrapped around the surface of a rotating shaft 105, and a rotating seat 103 is provided on one side of the rotating shaft 105.

[0032] A cavity is provided inside the base 12, and the fixing structure 7 includes a limit spring 705, the bottom of the limit spring 705 is fixedly connected to the bottom of the cavity, and a spring plate 706 is provided on the top of the limit spring 705, and a bevel is provided on one side of the spring plate 706. The front and rear sides of the top of the spring plate 706 are fixed with support rods 703, and both sides of the top of the support rod 703 are rotatably provided with fixed plates 704. A torque spring is provided at the rotational connection between the fixed plate 704 and the support rod 703, and a control plate 702 is rotatably provided at the top and bottom of the inner wall of the cavity. The front side of the control plate 702 passes through the base 12 and extends to the outside of the base 12, and a push block 701 is fixed on the front side of the control plate 702. A torque spring is provided at the rotational connection between the control plate 702 and the cavity, and pressing blocks 707 are fixed on both sides of the control plate 702;

[0033] The base 12 is internally rotated with an opposing screw rod 5, and a moving block 4 is threadedly connected to the opposing screw rod 5. A clamping block 3 is symmetrically arranged on the top of the moving block 4. An opposing threaded rod is provided inside the moving block 4, and the clamping block 3 is adapted to the opposing threaded rod. An adjusting block 10 is provided on the front of the opposing threaded rod, and the adjusting block 10 can control the movement of the clamping block 3. A moving groove is provided on the back of the clamping block 3, and a positioning spring is fixedly provided inside the moving groove. A movable block 9 is fixedly provided on one side of the positioning spring, and a splint 2 is rotatably provided on one side of the movable block 9, and a roller 11 is rotatably provided on one side of the clamping block 3.

[0034] A groove is provided at the bottom of the back of the base 12 , one side of the rotating seat 103 is rotatably connected to one side of the groove, and a fixed seat 104 is fixed on the other side of the groove. A card slot is provided on the front of the fixed seat 104 , and the card slot is adapted to one side of the rotating shaft 105 .

[0035] Slide grooves are provided on both sides of the top of the base 12 , and knobs 6 are provided on both sides of the base 12 . The knobs 6 can control the rotation of the opposing screw rods 5 .

[0036] The working principle and use process of the present invention are as follows: when the user uses a welding machine to weld the material, the base 12 is first placed directly below the welding head of the welding machine to determine the center position. When determining, check whether the position of the welding head and the center mark 101 are aligned. After alignment, place the material at the center position, and then turn the knob 6. The knob 6 drives the opposite screw rod 5 to rotate. The opposite screw rod 5 controls the movement of the moving block 4 to clamp the material. When clamping, the clamping block 3 will rotate adaptively to center the material. If the spacing between the clamping blocks 3 is large during clamping, the adjustment block can be rotated. 10 adjusts the position of the clamping block 3, which can be adjusted even when clamping. The roller 11 can reduce the friction between the clamping block 3 and the surface of the material. After clamping the material, welding can be carried out. The splashing welding slag and dripping melting point during welding will mostly fall on the heat-resistant paper 102. When the welding slag and melting point accumulate after long-term use, the user can replace the heat-resistant paper 102. When replacing, first push the push block 701, and the push block 701 drives the control board 702 to rotate. The control board 702 controls the spring plate 706 to move downward and downward through the pressing blocks 707 on both sides. The compression limit spring 705 and the spring plate 706 drive the support rod 703 to move downward, and the support rod 703 drives the fixing plate 704 to move downward. When the position of the fixing plate 704 is lower than the positioning hole opened at the top of the base 12, it will rotate and close with the rotation connection with the support rod 703 as the center of the circle. After closing, the fixing plate 704 will retract into the positioning hole. At this time, the heat-resistant paper 102 fixed by the fixing plate 704 can be pulled to one side. When the four holes on the new heat-resistant paper 102 are aligned with the positioning holes, the scraper 8 can be slid to remove the old heat-resistant paper 102. 02 is cut off and the new heat-resistant paper 102 is covered on it, then the push block 701 can be released, and the control board 702 will be restored to its original position by the torque spring. At this time, the fixing plate 704 will also be moved out of the positioning hole again and reopened to position the heat-resistant paper 102. The user can continue to use the base 12 for clamping and welding operations when it is normal. After the heat-resistant paper 102 is used up, the rotating shaft 105 can be moved to remove one end of the rotating shaft 105 from the fixing seat 104. After taking it out, the new heat-resistant paper 102 can be put back on and it can be continued to be used.
