Technical Field

[0001] The utility model relates to the technical field of spring machine tool seats, in particular to a clamping mechanism for a spring machine tool seat. Background Art

[0002] Spring machines, commonly known as spring machines, generally refer to mechanical equipment for producing springs. According to their functional characteristics, they are divided into compression spring machines, tension spring machines, universal machines, disc machines, and special spring machines such as snake spring machines and torsion spring machines. According to the driving mode, they are divided into semi-automatic, automatic, and CNC types. With the increase of industrial products, spring products have also become more abundant. Various special-shaped springs such as tower-shaped (commonly known as battery springs) springs, double torsion springs, etc. need to be made using spring machines, and the tool holder used needs to be limited by the clamping mechanism. After the tool holder is limited, the tool can be used to operate the workpiece.

[0003] The clamping mechanism is mainly used to clamp and limit the tool holder of the spring machine. After the tool holder is limited, the tool installed on the tool holder is also limited, thereby improving the quality of subsequent workpiece processing for spring production. However, the clamping mechanism often only has two clamping parts to clamp the two sides of the tool holder, and the other two sides of the tool holder cannot be clamped. The stability of the tool holder clamping is insufficient, and the size of the tool holder cannot be measured quickly. Therefore, the appropriate tool holder cannot be quickly replaced according to the size of the original tool holder, which reduces the use range of the clamping mechanism. Therefore, it is particularly important to design a clamping mechanism for the spring machine tool holder. Utility Model Content

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4 As shown, an extension plate 12 is provided on one side of one of the clamping plates 3, and one side of the extension plate 12 is slidably connected to one side of the measuring plate 10. A scale number 11 is provided on one side of the measuring plate 10 and the extension plate 12. The utility model provides a clamping mechanism for a spring machine tool holder. By providing a sponge pad 13, a positioning hole 8, a round hole and an anti-slip plate 16, when the side plates 9 approach each other, the sponge pad 13 moves accordingly. The sponge pad 13 is made of sponge and has a relatively soft surface. Therefore, when it contacts the outer surface of the workpiece, the squeezing force on the workpiece surface is reduced.

[0026] Working principle: The spring coiling machine is commonly known as the spring machine, which generally refers to the mechanical equipment for producing springs. The spring machine is equipped with a tool holder, and the tool holder needs to use a tool to process the workpiece. For this reason, the stability of the tool holder is very important, and a clamping mechanism is needed to clamp and limit the tool. The tool holder can be placed in the middle position of the two clamping plates 3 manually, and then the two servo motors 4 are started to drive the two screws 2 connected to the output shaft. When the two clamping plates 3 move relative to each other, they can gradually contact the two sides of the tool holder, thereby achieving the firmness of the tool holder. The moving block 6 can move left and right at one end of the support rod 5, so that the position of the side plate 9 can be adjusted smoothly. The relative movement of the two side plates 9 can clamp and limit the other two sides of the tool holder placed on the top of the spring machine. The two side plates 9 and the two clamping plates 3 cooperate with each other to achieve the purpose of clamping the tool holder around. After the side plate 9 clamps the tool holder, one end of the positioning rod 7 is embedded into the inside of the circular hole and the positioning hole 8 in turn, and the three are moved. The threaded rotation connection can limit and fix the clamping plate 3 and the side plate 9, thereby ensuring the firmness of the tool holder. The extension plate 12 can move left and right on one side of the measuring plate 10, so that the length of the tool holder can be measured according to the index conditions of the two. The index condition of the scale number 11 on one side of the measuring plate 10 is just flush with the side of the tool holder, and one side of the extension plate 12 is flush with the other side of the tool holder. Therefore, when the extension plate 12 moves, the value of the scale number 11 is checked, and the size of the tool holder can be measured, thereby increasing the use range of the clamping mechanism. When the side plates 9 approach each other, the sponge pad 13 moves with it. The sponge pad 13 is made of sponge and has a relatively soft surface. Therefore, when it contacts the outer surface of the workpiece, the extrusion force on the workpiece surface is reduced, avoiding damage to the surface of the workpiece. A large number of anti-skid patterns are provided on the bottom surface of the anti-skid disk 16. After starting the servo motor 4, it will drive the displacement plate 14 to move left and right, thereby adjusting the moving position of the two clamping plates 3.
