[0002] In the control components of salvage tools, the control key and control sleeve need to be welded together. Due to their unusual shapes, they are difficult to clamp. Currently, manual clamping and welding are done with pliers. This makes it difficult for the operator to ensure the correct positioning of the workpiece. After welding, the workpiece often deforms and warps, making it impossible to fit into the cylinder, and thus, the product quality cannot be guaranteed. Workshop technicians have increased the outer diameter allowance and removed the weld scars and deformation after welding to ensure the assembly quality of the product. However, this method greatly affects production efficiency. Summary of the Invention

[0003] In order to solve the above problems, the utility model provides a clamping device for salvage tool welding, the purpose of which is to ensure the relative position of each welded part is accurate and the clamping is stable, reduce processing difficulty and improve production efficiency.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a clamping device for welding salvage tools, comprising a first clamping plate, a second clamping plate, a clamping piece, a pressure block, a column, a rocker arm and a clamping stud, a handle, and a pin. The clamping piece is connected to the first clamping plate and the second clamping plate so that the second clamping plate moves close to the first clamping plate. The first clamping plate and the second clamping plate are disc-shaped, and the outer periphery of the mating end of the second clamping plate and the clamped part is chamfered. The first clamping plate cuts out a plane along the circumferential direction, and the column is provided with a planar groove radially along the second clamping plate and is welded and fixedly connected to the second clamping plate. The rocker arm is provided with a through hole that cooperates with the column and a threaded hole that cooperates with the clamping stud, and the pressure block abuts the clamping stud and the welded part respectively.

[0005] The clamping part includes a clamping bolt and a clamping nut. A through hole is provided in the center of the first clamping plate, and the clamping bolt passes through the through hole and is fixedly connected to the first clamping plate. A through hole is provided in the center of the second clamping plate, and the clamping bolt passes through the through hole and is connected to the clamping nut. The second clamping plate is also provided with a loading and unloading groove connected to the through hole.

[0006] The outer periphery of the second clamping plate and the clamping end that cooperates with the inner hole of the clamped piece are provided with a chamfer, and the chamfer angle is the same as the chamfer of the matching surface of the clamped piece.

[0007] It also includes a handle, which is provided with a slide groove, and the handle is connected to the clamping stud through a cylindrical pin.

[0008] The beneficial effects of the present invention are as follows: since the control card key and the control card sleeve in the control component of the salvage tool both have an inclined angle, the present invention ensures that the control card key and the control card sleeve fit the card plate by providing a first clamping plate and a second clamping plate with chamfers and loading and unloading grooves, thereby achieving accurate relative position of parts and stable clamping, and rapid assembly, clamping and disassembly. At the same time, the clamping stud applies force to the pressing block to achieve clamping of the control card key and positioning of the control card key by the circumferentially cut-out plane of the first clamping plate.

[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0016] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments. Example

[0017] like Figures 1 to 4As shown, the utility model provides a clamping device for welding salvage tools, including a first clamping plate 1, a second clamping plate 2, the first clamping plate 1, the second clamping plate 2 and a clamping nut 8 to form a clamping piece, a pressure block 3, a column 4, a rocker arm 5 and a clamping stud 6. The clamping piece is connected to the first clamping plate 1 and the second clamping plate 2 so that the second clamping plate 2 moves close to the first clamping plate 1. The first clamping plate 1 and the second clamping plate 2 are disc-shaped, and the outer periphery of the second clamping plate 2 is matched with the inner hole of the clamped part, and the clamping end is provided with a chamfer, and the chamfer angle is the same as the chamfer of the matching surface of the clamped part. The first clamping plate 1 cuts out a plane along the circumferential direction, and the column 4 is provided with a plane groove radially along the second clamping plate 2 and is welded and fixedly connected to the second clamping plate. The rocker arm 5 is provided with a through hole that cooperates with the column 4 and a threaded hole that cooperates with the clamping stud 6, and the pressure block 3 abuts against the clamping stud 6 and the control key of the welded part respectively.

[0018] Because the control key and control sleeve in the fishing tool control component both have an inclination angle, the present invention ensures that the control key and control sleeve fit closely together with the first and second plates 1 and 2 by providing a first clamping plate 1 and a chamfered second clamping plate 2, achieving accurate relative positioning of the parts and stable clamping. Specifically, the inclination angle of the control key and control sleeve is 60°, so the chamfer is also 60°.

[0019] Specifically, the clamping part includes a first clamping plate 1, a clamping bolt 7 and a clamping nut 8. A through hole is provided in the center of the first clamping plate, the clamping bolt 7 passes through the through hole and is fixedly connected to the first clamping plate 1, and a clamping nut 8 is provided near the end of the second clamping plate; a through hole is provided in the center of the second clamping plate 2, and the second clamping plate 2 is also provided with a loading and unloading groove 11 connected to the through hole, the clamping bolt 7 passes through the through hole of the second clamping plate and is connected to the clamping nut 8. The function of the loading and unloading groove 11 is to facilitate the rapid assembly and disassembly of the clamping part of this device and the welded workpiece control sleeve, so as to realize rapid clamping and disassembly. It is specifically implemented as follows: after the bolt 7 passes through the inner hole of the clamped part control sleeve, it is positioned from the loading and unloading groove 11 of the second clamping plate to the through hole of the second clamping plate, and then the clamping nut 8 is tightened to clamp the workpiece. After loosening the clamping nut 8, it is quickly removed from the loading and unloading groove 11 of the second clamping plate. The clamping bolt 7 is welded and fixed to the first clamping plate 1, and the control clamping sleeve is placed between the first clamping plate 1 and the second clamping plate 2. By rotating the clamping nut 8, the second clamping plate 2 is moved close to the first clamping plate 1 to achieve the clamping positioning of the control clamping sleeve.

[0020] Specifically, it also includes a handle 9 with a slide groove, and the handle 9 is connected to the clamping stud 6 via a cylindrical pin 10. The rocker arm 5 can rotate around the column 4, thereby driving the clamping stud 6 to rotate to adjust the position of the clamping stud 6 acting on the clamping block 3. By rotating the handle 9, the clamping stud 6 applies force to the clamping block 3, thereby clamping the control key. The first clamping plate 1 cuts out a plane along the circumference for positioning and supporting the welded control key.

[0021] In addition to the above-mentioned preferred embodiments, the present invention has other implementation methods. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
