Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, and more specifically to a press-fitting tooling for a tensioning device. Background Art

[0002] During the production process of the tensioning device, a spring needs to be press-fitted. At the same time, the diameter of the spring is very large, and a large torque needs to be applied during the pressing process. However, due to the special structure and performance of the spring, when it is compressed, a force perpendicular to the spring extension direction will be generated at the contact part between the spring end and the base of the tensioning device, that is, the spring end will have a tendency to rotate. Under the action of friction, the base of the tensioning device will rotate, resulting in deviation of the produced base of the tensioning device. At the same time, it may also lead to accidents during the press-fitting process. There is a need for a press-fitting tooling that can fix the base of the loading device. Summary of the Utility Model

[0003] One advantage of the utility model is to provide a press-fitting tooling for a tensioning device, which is provided with a pressing plate that can move up and down and a fixed base. The two ends of the tensioning device are fixed by the pressing plate and the base. In this way, when the spring is pressed in, even if the cylinder of the tensioning device receives torque and has a tendency to rotate, it will not be able to rotate because it is fixed by the pressing plate and the base, thus ensuring the product quality.

[0004] One advantage of the utility model is to provide a press-fitting tooling for a tensioning device. A rectangular unclosed shell is formed by a bottom plate, a support plate and a top plate. The width of the shell is slightly larger than the width of the tensioning device. On the one hand, it is convenient to put the tensioning device into the device, and on the other hand, it can also play a certain fixing effect.

[0005] One advantage of the utility model is to provide a press-fitting tooling for a tensioning device, which is connected and fixed by screws, facilitating the disassembly and recombination of the whole structure, so as to be able to adapt to the press-fitting operations of various models of tensioning devices, achieving the effects of cost saving and efficiency improvement.

[0006] One advantage of the utility model is to provide a press-fitting tooling for a tensioning device. By rotating the screw rod, the pressing plate moves up and down. The moving trend of the pressing plate is vertical up and down, while the screw rod moves along the thread, thus ensuring a one-way interaction relationship, that is, rotating the screw rod can drive the pressing plate to move up and down, but the pressing plate cannot drive the screw rod to rotate through up and down movement. This kind of press-fitting method only needs to press the pressing plate in place to achieve the fixing effect, without the need for an additional fixing structure. At the same time, a guide rod is provided to ensure that the pressing plate can only move up and down.

[0007] To achieve at least one of the above advantages of the present utility model, the present utility model provides a press-fitting tooling for a tensioning device, including a bottom plate. On both sides of the bottom plate, there are support plates perpendicular to the bottom plate. At the upper ends of the support plates, there are top plates fixedly arranged. On the top plates, there is a screw rod arranged in a movable manner. The lower end of the screw rod is connected to a pressing plate in a relatively rotatable manner, and the upper end of the screw rod is connected to a handle.

[0008] According to an embodiment of the present utility model, two bases are arranged on the upper part of the bottom plate, and both of the two bases are respectively arranged close to the inner sides of the two support plates.

[0009] According to an embodiment of the present utility model, the width of the top plate is equal to the sum of the thicknesses of the support plate and the base. The outer vertical surface of the top plate is flush with the outer side surface of the support plate. A vertical threaded hole is arranged on the inner part of the top plate, and an external thread meshing with the internal thread in the threaded hole is arranged on the outer vertical surface of the screw rod.

[0010] According to an embodiment of the present utility model, the pressing plate is located directly above the base.

[0011] According to an embodiment of the present utility model, two guiding columns are further arranged at the lower end of the top plate, and through holes matching with the guiding columns are arranged on the pressing plate. When the top plate moves up and down, the through holes move up and down along the guiding columns.

[0012] According to an embodiment of the present utility model, it further includes screws, and both between the support plate and the bottom plate and between the support plate and the top plate are connected by screws.

[0013] According to an embodiment of the present utility model, an end plate is fixedly arranged at one end of the bottom plate, and both sides of the end plate are also fixedly connected to the support plate and the top plate. Description of the Drawings

On the top plate 4, there is a screw rod arranged in a movable manner. The lower end of the screw rod is connected to a pressing plate 5 in a relatively rotatable manner. The upper end of the screw rod is connected to a handle 6. At the upper part of the bottom plate 1, there are two bases 2, and the two bases 2 are respectively arranged closely against the inner sides of the two support plates 3. The width of the top plate 4 is equal to the sum of the thicknesses of the support plate 3 and the base 2. The outer vertical surface of the top plate 4 is flush with the outer side surface of the support plate 3. On the inner part of the top plate 4, there is a vertical threaded hole, and on the outer vertical surface of the screw rod, there is an external thread meshing with the internal thread in the threaded hole. The pressing plate 5 is located directly above the base 2. At the lower end of the top plate 4, there are also two guide posts 7, and on the pressing plate 5, there are through holes matching with the guide posts 7. When the top plate 4 moves up and down, the through holes move up and down along the guide posts 7. It also includes screws 8. The support plate 3 is connected to the bottom plate 1 and the top plate 4 through screws 8. One end of the bottom plate 1 is fixedly provided with an end plate, and both sides of the end plate are also fixedly connected to the support plate 3 and the top plate 4.

[0023] The first embodiment of the present utility model is as follows:

[0024] A press-fitting tool for a tensioning device, comprising a bottom plate 1. On both sides of the bottom plate 1, there are two support plates 3 perpendicular to the bottom plate 1. At the upper ends of the support plates 3, there are top plates 4 fixedly arranged. In the middle of the top plate 4, there is a screw rod arranged in a movable manner. On the inner side part of the top plate 4, there is a vertical threaded hole. On the outer vertical surface of the screw rod, there is an external thread meshing with the internal thread in the threaded hole. By rotating, the screw rod can rotate and move up and down along the threaded hole. The lower end of the screw rod is connected to a pressing plate 5 in a relatively rotatable manner, which can be connected by setting bearings. The upper end of the screw rod is fixedly connected to a handle 6.

[0025] The bottom plate 1, the support plates 3 and the top plate 4 form a rectangular and unclosed housing. The width of this housing is slightly larger than the width of the tensioning device. On the one hand, it is convenient to put the tensioning device into this device. On the other hand, it can also play a certain fixing effect.

[0026] On the upper part of the bottom plate 1, there are two bases 2. The two bases 2 are respectively arranged closely against the inner sides of the two support plates 3. The width of the top plate 4 is equal to the sum of the thicknesses of the support plates 3 and the bases 2. The outer vertical surface of the top plate 4 is flush with the outer side surfaces of the support plates 3. The two pressing plates 5 are respectively located directly above the two bases 2, ensuring the accuracy and stability of the press-fitting.

[0027] The pressing plate 5 that can move up and down and the fixed base 2 are provided. The two ends of the tensioning device are fixed by the pressing plate 5 and the base 2. In this way, when the spring is pressed in, even if the cylinder of the tensioning device receives torque and has a tendency to rotate, it will not be able to rotate because it is fixed by the pressing plate 5 and the base 2, thus ensuring the product quality.

[0028] By rotating the screw rod, the pressing plate 5 moves up and down. The moving trend of the pressing plate 5 is to move vertically up and down, while the screw rod moves along the thread, thus ensuring a one-way interaction relationship, that is, rotating the screw rod can drive the pressing plate 5 to move up and down, but the pressing plate 5 cannot drive the screw rod to rotate by moving up and down. This kind of press-fitting method only needs to press the pressing plate 5 in place to achieve the fixing effect, without the need for additional fixing structures.

[0029] Further preferably, there are also two guiding columns 7 arranged at the lower end of the top plate 4. There are through holes on the pressing plate 5 that cooperate with the guiding columns 7. When the top plate 4 moves up and down, the through holes move up and down along the guiding columns 7.

[0030] Further preferably, it also includes screws 8. The support plates 3 are connected to the bottom plate 1 and the top plate 4 through the screws 8. By connecting and fixing with the screws 8, it is convenient to disassemble and recombine the whole structure, so as to be able to adapt to the press-fitting operations of various models of tensioning devices, achieving the effects of cost saving and efficiency improvement.

[0031] Further preferably, one end of the bottom plate 1 is fixedly provided with an end plate, and both sides of the end plate are also fixedly connected to the support plate 3 and the top plate 4. The end plate can abut against one end of the tensioning device, thereby facilitating the pressing installation of the spring.

[0032] In actual use, first rotate the handle 6 to move the pressing plate 5 upward to ensure there is enough distance between the pressing plate 5 and the base 2, and then place the end of the tensioning device into it until one end abuts against the end plate. At this time, rotate the handle 6 to move the pressing plate 5 downward until the pressing plate 5 and the base 2 clamp and fix the tensioning device from the upper and lower ends. At this time, use tools to press and fix the spring and the end cover to complete the work.

[0033] It should be noted that the terms "first", "second" and "third" in the present utility model are only for descriptive purposes, do not represent any order, and cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0034] Those skilled in the art should understand that the embodiments of the present utility model described above and shown in the drawings are only examples and do not limit the present utility model. The advantages of the present utility model have been fully and effectively realized. The functions and structural principles of the present utility model have been shown and described in the embodiments.
