Description

Technical Field

[0001] The invention relates to the technical field of automobile shock absorber welding devices, in particular to an automobile shock absorber welding device. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure.

It includes a base plate, and the middle part of both sides of the upper end of the base plate is connected to a support plate. According to this patent, rotating the first hand wheel and the second hand wheel respectively can adjust the right clamping mechanism and the left clamping mechanism laterally, so that the distance between the two mechanisms can be adjusted, thereby adapting to the clamping and fixing of different positions during welding; the shock absorber is clamped in the middle in a triangular shape by two first rollers and the second roller, and the shock absorber is manually rotated. Under the rolling connection of the two first rollers and the second roller, the shock absorber can be rotated, thereby facilitating the reversing welding of the shock absorber. Compared with the existing multiple reversing operations, this new reversing operation is convenient and fast, and effectively improves work efficiency.

[0004] In the above patent, the reversing welding of the shock absorber is convenient. Compared with the existing multiple reversing operations, the new reversing operation is convenient and fast, and effectively improves the work efficiency. However, when the claw clamps the steel pipe, the clamping force of the claw clamp on the steel pipe may be insufficient, so that the steel pipe cannot support alignment, which affects the welding of the steel pipe. In addition, when clamping the steel pipe, the pipe head of the steel pipe may be damaged, which affects the welding of the steel pipe. Summary of the Invention

The support plate is driven by the movement of the slider to support the steel pipe, so as to avoid the steel pipe being unable to support and align due to insufficient clamping force on the steel pipe during docking, which affects the welding of the steel pipe.

[0007] According to the above technical solution, a No. 1 gasket is provided on the other side of the claw clamp, and a No. 1 spring is provided between the No. 1 gasket and the claw clamp. The No. 1 spring is provided to enable the No. 1 gasket to retract and squeeze the No. 1 spring when clamping the steel pipe to avoid squeezing and deforming the steel pipe.

[0009] According to the above technical solution, a circular hole is opened on the side of the fixing frame close to the pin, and the pin slides inside the circular hole. The circular hole is provided to limit the baffle when the pin is inserted into the circular hole.

[0011] According to the above technical solution, the detection device includes a No. 1 oblique block, a No. 2 oblique block, a lower arc plate, an upper arc plate, a long rod, a telescopic rod, a round rod, an inner plate, a No. 2 short rod and an outer plate, the lower arc plate is movably fixedly mounted on the upper surface of the support platform, the No. 2 short rod is slidably mounted on the upper surface of the lower arc plate, the upper arc plate is fixedly mounted on the upper surface of the lower arc plate, a sliding groove is provided on the surface of the upper arc plate, the No. 1 oblique block is slidably mounted inside the sliding groove, the No. 2 oblique block is fixedly mounted on the upper surface of the No. 1 oblique block, the inner plate is fixedly mounted on the side of the No. 1 oblique block away from the fixed plate, and the outer plate and the inner plate are symmetrically arranged on the vertical center axis of the lower arc plate.

The telescopic rod is slidably installed inside the No. 2 square groove. A fixing hole is provided on the circumferential surface of the turntable. One end of the round rod is slidably installed inside the fixing hole, and the other end of the round rod is fixedly installed on one end of the telescopic rod. Only when the steel pipe presses down the No. 2 oblique block by an equal distance can the inner plate slide toward the inside of the outer plate to release the limit on the turntable and rotate the turntable. When the pressing distance is unequal, the turntable cannot rotate, so that the steel pipe cannot be completely welded, so as to avoid the impact of incomplete welding of the steel pipe on subsequent use.

[0012] According to the above technical solution, a No. 2 circular hole is opened on the upper surface of the No. 1 inclined block, and the other end of the No. 2 short rod is slidably installed inside the No. 2 circular hole.

The No. 2 slide groove is provided so that the inner plate can move toward the inside of the outer plate when the outer plate and the inner plate are in the same position. The long rod is fixedly installed on the other end of the telescopic rod, and a protrusion is fixedly installed on the upper surface of the inner plate. The protrusion is fixedly installed to limit the inner plate when the No. 2 inclined block is not pressed.

[0014] The present invention provides a welding device for automobile shock absorbers. It has the following beneficial effects: (1) This invention requires clamping the steel pipe for welding. When the steel pipe is placed at the front end of the turntable, the slider will move toward the steel pipe. The movement of the slider will push the claw to move, and the movement of the claw will clamp the steel pipe. The movement of the claw will move the No. 1 gasket to prevent the steel pipe from being clamped. The movement of the slider drives the claw to clamp the steel pipe, and the movement of the slider drives the support plate to support the steel pipe, so as to avoid the claw's insufficient clamping force on the steel pipe, which makes it impossible to support and align the steel pipe and affect the welding of the steel pipe.

[0015] (2) In this invention, when the slider moves, it drives the pull plate to move. The movement of the pull plate squeezes the No. 1 hydraulic rod to slide inside the No. 1 hydraulic cylinder, pushing the liquid inside the No. 1 hydraulic cylinder into the No. 2 hydraulic cylinder. The liquid entering the No. 2 hydraulic cylinder pushes the No. 2 hydraulic rod to move. The movement of the No. 2 hydraulic rod pushes the ring to move. The baffle blocks the descent of the welding head so that the welding head will not continue to descend after it descends to a certain position, thereby preventing the welding head from descending too much and causing the welding head to contact with the steel pipe, causing the welding head to be squeezed and damaged, thereby affecting the welding.

[0016] (3) In this invention, when the claw clamp fully clamps the steel pipe, the fixed plate will push the steel pipe to move toward the support platform. When the steel pipe moves a certain distance, it will contact the upper arc plate. When the steel pipe moves on the upper surface of the upper arc plate, it will contact the No. 2 inclined block and push the No. 2 inclined block downward. Whether the inner plate can move toward the inside of the outer plate is controlled by whether the downward pressure distance of the steel pipe on the No. 2 inclined block is equal. When the downward pressure distance is equal, the inner plate can slide toward the inside of the outer plate to squeeze the long rod, so that the round rod releases the limit on the turntable. Only when the downward pressure distance of the steel pipe on the No. 2 inclined block is equal can the inner plate slide toward the inside of the outer plate to release the limit on the turntable and allow the turntable to rotate. When the downward pressure distance is unequal, the turntable cannot rotate, so that the steel pipe cannot be completely welded, avoiding the impact of incomplete welding of the steel pipe on subsequent use.
