Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a testing device for resistance aluminum spot welding clamps. Background Technology

[0002] A spot welding pliers is a tool used in resistance spot welding. It is primarily used to clamp and apply pressure to the workpiece to be welded. It is widely used in industries such as automotive manufacturing, home appliances, and electronics. The basic structure of a spot welding pliers typically includes electrodes, a handle, a conductive part, and a pressure system. The electrode part is responsible for conducting electricity and transferring current to the welding point, while the handle provides support for the operator. The conductive part is usually made of a material with good conductivity (such as copper) to ensure efficient current conduction during welding. The pressure system of the welding pliers is responsible for applying a certain amount of pressure to maintain good contact between the workpiece and the electrode so that current can pass smoothly.

[0003] The existing testing equipment for resistance aluminum spot welding clamps requires personnel to hold the equipment by hand during use, which causes fatigue due to prolonged hand gripping and the equipment is prone to loosening from the body, posing a threat to personal safety. In addition, during the disassembly and maintenance of the equipment, personnel have to turn bolts and nuts to separate the insulating and heat-insulating sleeve from the clamp body, which is time-consuming and laborious. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a testing device for resistance aluminum spot welding clamps, which has the advantages of stable clamping during welding and easy disassembly and assembly of the insulating and heat-resistant sleeve, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a testing device for resistance aluminum spot welding clamps, comprising a clamp body, an adjusting rod rotatably connected to the outer wall of the clamp body, a short rod fixedly installed at the bottom of the adjusting rod, a first spring installed at the bottom of the short rod, a sleeve installed at one end of the first spring, an insulating and heat-insulating sleeve slidably connected to the outer wall of the clamp body, a support rod fixedly installed on the outer wall of the insulating and heat-insulating sleeve, a cylinder fixedly installed at the top of the support rod, a round rod installed on the inner wall of the cylinder, a third spring fixedly installed at the bottom of the round rod, a pressure plate fixedly connected to the top of the round rod, a fixing rod fixedly installed on the outer wall of the clamp body, a locking block fixedly installed on the outer wall of the fixing rod, a second spring fixedly connected to the inner wall of the insulating and heat-insulating sleeve, a round plate fixedly installed at one end of the second spring, a locking groove and a round groove formed on the inner wall of the insulating and heat-insulating sleeve.

[0006] As a preferred technical solution of this utility model: one end of the first spring is fixed to the bottom of the short rod, and the other end of the first spring is fixed to the inner wall of the sleeve.

[0007] As a preferred technical solution of this utility model: the number of pressure plates is several, and the outer wall of the several pressure plates is semi-arc.

[0008] As a preferred technical solution of this utility model: the inner wall of the cylinder is slidably connected to the outer wall of the rod, and the other end of the third spring is fixed to the inner wall of the cylinder.

[0009] As a preferred technical solution of this utility model: the inner wall of the insulating and heat-insulating sleeve is provided with a sliding groove, and the outer wall of the sliding groove is adapted to the outer wall of the card block.

[0010] As a preferred technical solution of this utility model: the outer wall of the circular plate and the outer wall of the circular groove are slidably connected, and the outer wall of the slot is engaged with the outer wall of the block.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This testing device for resistance aluminum spot welding clamps uses several pressure plates with semi-circular outer walls. A person's hand passes through the outer wall of the support rod and uses their fingers to press against the outer wall of the pressure plate, which increases the comfort of the human hand grip. As the fingers press against the pressure plate, the pressure plate pushes the round rod to press against the third spring, so that the pressure plate can be adjusted according to different hand sizes. The elastic force of the third spring pushes the pressure plate to fit against the insulating and heat-insulating sleeve, achieving clamping and fixing.

[0013] 2. The testing equipment for resistance aluminum spot welding clamps uses clamp body to drive a fixed rod into the inner wall of the insulating heat insulation sleeve. The fixed rod drives a locking block to slide on the outer wall of the slide groove, so that the outer wall of the fixed rod overlaps with the outer wall of the circular plate. The fixed rod drives the locking block to abut against the circular plate, causing the second spring to compress. External force rotates the insulating heat insulation sleeve, causing the locking block to engage with the locking groove. The second spring releases the tension, making the connection between the clamp body and the insulating heat insulation sleeve stable. Attached Figure Description

[0023] In a preferred embodiment, one end of the first spring 8 is fixed to the bottom of the short rod 9, and the other end of the first spring 8 is fixed to the inner wall of the sleeve 10.

[0024] In the above structure, by pressing the adjusting rod 4 with external force, the adjusting rod 4 drives the short rod 9 to abut against the first spring 8, compressing it and causing the adjusting rod 4 to separate from the clamp body 1. The material is placed on the top of the clamp body 1. The adjusting rod 4 is released by external force, and the elastic force of the first spring 8 enables the adjusting rod 4 and the clamp body 1 to clamp the material.

[0025] In a preferred embodiment, there are several pressure plates 7, and the outer walls of the several pressure plates 7 are semi-circular.

[0026] In the above structure, the outer walls of several pressure plates 7 are semi-circular, allowing a person to pass through the outer wall of the support rod 3 and place their fingers against the outer wall of the pressure plate 7, thereby increasing the comfort of the human hand grip.

[0027] In a preferred embodiment, the inner wall of the cylinder 5 is slidably connected to the outer wall of the rod 6, and the other end of the third spring 15 is fixed to the inner wall of the cylinder 5.

[0028] In the above structure, the pressure plate 7 is pressed against the third spring 15 by the fingers touching the pressure plate 7, and the pressure plate 7 pushes the round rod 6 to press against the third spring 15, so that the pressure plate 7 can be adjusted according to different hand sizes.

[0033] Working principle: By pressing the adjusting rod 4 with external force, the adjusting rod 4 drives the short rod 9 to abut against the first spring 8, compressing it and separating the adjusting rod 4 from the clamp body 1. The material is placed on the top of the clamp body 1. The adjusting rod 4 is then released with external force. The elastic force of the first spring 8 allows the adjusting rod 4 and the clamp body 1 to clamp the material. Several pressure plates 7 have semi-circular outer walls. A person's hand passes through the outer wall of the support rod 3, and their fingers are placed against the outer wall of the pressure plate 7, increasing the comfort of the hand grip. With the fingers against the pressure plate 7, the pressure plate 7 pushes the round rod 6 to abut against the third spring 15, allowing the pressure plate 7 to adjust according to different hand positions. The size is adjusted, and the pressure plate 7 is pushed to fit against the insulating heat insulation sleeve 2 by the elastic force of the third spring 15 to achieve clamping and fixation. The clamp body 1 drives the fixing rod 18 into the inner wall of the insulating heat insulation sleeve 2. The fixing rod 18 drives the locking block 16 to slide on the outer wall of the slide groove 14, so that the outer wall of the fixing rod 18 overlaps with the outer wall of the circular plate 11.
