Description
Technical Field
[0001] The utility model relates to the technical field of welding spot stripping, in particular to a vehicle body welding spot stripper. Background Art
[0002] Cars are usually made of sheet metal, and most car manufacturers use spot welding to assemble the sheet metal. When disassembling a car, the master needs to destroy the welds while ensuring that the sheet metal of the car body does not deform, and then peel off the sheet metal. In the prior art, a crowbar and a hammer are usually used to cooperate with each other to destroy the welds of the car body. The pry head of the crowbar is aimed at the weld of the car body or the gap near the weld, and then the hammer is used to hit the handle of the crowbar. However, the crowbar is usually L-shaped. When hitting the handle, the pry head of the crowbar is easy to deviate, and it is also easy to cause the handle to bend and deform, so that the weld of the car body cannot be accurately destroyed, and it is also easy to cause deformation of the sheet metal of the car body. Utility Model Content
[0003] The utility model aims to provide a car body welding spot stripper, which can prevent the prying head of a crowbar from being offset when destroying the welding spot, thereby affecting the destruction of the welding spot, and can also prevent the worm of the crowbar from being bent and deformed due to knocking.
[0004] The above technical objectives of the utility model are achieved through the following technical solutions:
[0005] A car body weld spot stripper, comprising a gripping rod, one end of the gripping rod is provided with a prying head perpendicular thereto, an end of the prying head close to the gripping rod is provided with a cylindrical shell along its length direction, a limiting ring is provided inside the cylindrical shell, a first connecting rod slidably connected to the limiting ring is slidably connected inside the cylindrical shell, a first limiting block slidably connected to the cylindrical shell is provided on one side of the limiting ring on the outside of the first connecting rod, a second limiting block slidably connected to the cylindrical shell is provided on the other side of the limiting ring on the outside of the first connecting rod, and a first spring is provided between the second limiting block and the cylindrical shell on the outside of the first connecting rod;
[0006] A knocking block is provided at the end of the first connecting rod away from the prying head, a limiting opening is formed at the end of the holding rod close to the prying head, a limiting rod is horizontally provided inside the limiting opening, a sliding block slidably connected to the limiting opening is slidably connected to the outer side of the limiting rod, a second spring is provided on the outer side of the limiting rod between the end of the sliding block away from the prying head and the limiting opening, and a second connecting rod rotatably connected to the knocking block is rotatably connected to the end of the sliding block close to the knocking block.
[0007] By adopting the above technical solution, when stripping the weld spot of the car body, hold the handle with your hand, then aim the pry head at the weld spot or the gap between the sheet metal and the weld spot, and then use a hammer to knock the striking block, the striking block drives the first connecting rod to slide relative to the cylindrical shell, the movement of the first connecting rod drives the first limit block and the second limit block to slide in the cylindrical shell, the second limit block compresses the first spring, the first limit block is driven by the first connecting rod to knock the limit ring, driving the pry head to impact the weld spot, thereby destroying the weld spot, the striking block moves over During the process, the second connecting rod is driven to rotate relative to the knocking block, and the second connecting rod drives the sliding block to slide relative to the limit opening and the limit rod. At the same time, the sliding block compresses the second spring to alleviate a part of the knocking force generated by the hammer knocking the knocking block, to prevent the handle from being bent and deformed due to the knocking, to ensure that the knocking force will only drive the prying head to impact the welding point, to prevent the prying head from deviating, and to fail to accurately damage the welding point. After the second limit block knocks the limit ring, the elastic force of the first spring and the elastic force of the second spring can drive the knocking block to return to its original position.
[0008] The utility model is further configured as follows: a rubber grip is provided at one end of the grip rod away from the pry head.
[0009] The utility model is further configured as follows: a first inclined surface inclined from outside to inside is arranged on the left and right sides of one end of the prying head away from the handle, and a second inclined surface arranged adjacent to the first inclined surface and inclined from outside to inside is arranged on the end of the prying head away from the handle.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] The knocking block can prevent the prying head from deviating when destroying the welding point, and can also prevent the handle from bending and deforming when being knocked, thereby affecting the destruction of the welding point. By knocking the knocking block, the knocking block slides, and then drives the first connecting rod to slide relative to the cylindrical shell, and the connecting rod drives the first limit block to knock the limit ring, thereby driving the prying head to produce impact and destroy the welding point. At the same time, the knocking block drives the slider to slide in the limit opening through the second connecting rod, compressing the second spring, and alleviating part of the impact force generated by the knocking, thereby preventing the handle from being deformed due to the impact force, and at the same time ensuring that the impact force received by the prying head is in the vertical direction to prevent it from deviating.
