[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 7 As shown, the utility model discloses a compression spring installation tool, comprising a workbench 1, a compression spring 2, a mounting seat 3 that slides back and forth along the workbench 1, a workpiece 4 to be processed located on the mounting seat 3, a matching seat 5 located above the mounting seat 3 and equipped with the compression spring 2, and a driving member 6 for driving the matching seat 5 to move (the driving member 6 can be a different structure that can drive the matching seat 5 to move up and down, such as an electric push rod 531, a cylinder, etc., in this embodiment, the driving member 6 is a cylinder), a push rod 531 is movably installed on the matching seat 5, and a push rod 531 is provided on the workpiece 4 for the compression spring 2 to be installed. The positioning groove 41 is provided on the matching seat 5, and a moving groove 511 for the compression spring 2 to move downward is provided. The front side of the mounting seat 3 is rotatably mounted with a matching wheel 31. The front side of the matching seat 5 is fixedly mounted with a driving plate 521 by integral molding, welding, etc. The driving plate 521 includes a driving surface 5211 at the bottom, and the driving surface 5211 is inclined from top to bottom and from back to front. The workbench 1 is provided with a reset component 7 on the front side of the mounting seat 3. When the compression spring 2 needs to be installed on the workpiece 4 to be processed (the workpiece 4 to be processed at this time may be a workpiece to be installed), the workbench 1 is provided with a reset component 7 on the front side of the mounting seat 3. When the handle or other object of the compression spring 2 is placed on the mounting seat 3 (a panel in this embodiment), the workpiece 4 to be processed is first placed on the mounting seat 3. Because the compression spring 2 is located on the matching seat 5, the starting driving member 6 can drive the driving plate 521 to move downward. At this time, the driving surface 5211 of the driving plate 521 will contact the matching wheel 31 of the mounting seat 3. As the driving surface 5211, which is arranged from top to bottom and from back to front, continues to move downward, it will push the roller to move forward and drive the mounting seat 3 to move. As the driving plate 521 moves downward and the mounting seat 3 moves forward, the positioning groove 41 on the workpiece 4 to be processed will be aligned with the movable groove 511 on the matching seat 5, that is, the movable groove 511 is located above the positioning groove 41. At this time, by moving the push rod 531 downward, the compression spring 2 on the matching seat 5 can be pushed downward and enter the positioning groove 41 through the movable groove 511, thereby completing the installation of the compression spring 2 in the positioning groove 41. Compared with the traditional manual operation method, the above process can effectively improve the accuracy of the compression spring 2 being installed in the positioning groove 41 and provide convenience for the compression spring 2 to be installed in the workpiece 4 to be processed.

[0030] Among them, the mounting seat 3 includes a guide platform 33 at the bottom, and the left and right sides of the guide platform 33 are respectively provided with a first matching groove 331 and a second matching groove 332. The workbench 1 is located on the left and right sides of the mounting seat 3 and is respectively protruded with a first mounting plate 11 and a second mounting plate 12. The first mounting plate 11 and the second mounting plate 12 respectively include a first matching plug-in block 111 and a second matching plug-in block 121 located above the first matching groove 331 and the second matching groove 332. Since the first matching groove 331 and the second matching groove 332 on the bottom guide platform 3 will always be in contact with the corresponding first matching plug-in block 111 and the second matching plug-in block 121 during the forward and backward movement of the mounting seat 3, the first matching groove 331 and the second matching groove 332 will always be in contact with the corresponding first matching plug-in block 111 and the second matching plug-in block 121. Therefore, the first matching plug-in block 111 and the second matching plug-in block 121 can provide guidance for the forward and backward movement of the guide platform 33.

[0031] Among them, a processing position 34 is provided on the mounting seat 3 corresponding to the workpiece 4 to be processed, and a number of positioning blocks 35 are protruding upward from the mounting seat 3 in the processing position 34, and a positioning slot 42 for the corresponding positioning blocks 35 to be inserted is provided on the workpiece 4 to be processed. After the workpiece 4 to be processed is placed in the processing position 34, the positioning blocks 35 on the mounting seat 3 will be inserted into the corresponding positioning slots 42 on the workpiece 4 to be processed. At this time, the relative position of the workpiece 4 to be processed and the mounting seat 3 is determined, so that when the mounting seat 3 slides back and forth compared to the workbench 1, the workpiece 4 to be processed can be stably located on the mounting seat 3.

[0032] Preferably, the mating seat 5 includes a first mating plate 52, a second mating plate 53 and a third mating plate 51, the compression spring 2 and the movable groove 511 are both located on the third mating plate 51, the third mating plate 51 is located at each vertex and is fixedly connected with a sliding rod 512 by means of integral molding or the like, the first mating plate 52 is linked with the driving member 6, the driving plate 521 is fixedly connected with the first driving plate 521 by means of integral molding or the like, the second mating plate 53 is located below the first mating plate 52 and slides up and down along each sliding rod 512, the push rod 531 is located on the second mating plate 53, and when the driving member 6 is working, the driving member 6 will drive the first mating plate 52 and the driving plate located in front of the first mating plate 52 521 moves downward, and at this time the driving plate 521 can drive the mounting seat 3 where the mating wheel 31 is located to slide forward. At the same time, as the first mating plate 52 and the driving plate 521 move downward, the second mating plate 53 located below the first mating plate 52 can move up and down along the sliding rods 512 at the top corners of the third mating plate 51, so that the push rods 531 located on the second mating plate 53 will be downward and exert a downward force on the compression spring 2 located on the third mating plate 51, driving the compression spring 2 downward through the moving groove 511 and then located in the positioning groove 41 of the workpiece 4 to be processed. Therefore, the operation of the driving member 6 can drive multiple components to work, so that the compression spring 2 can fall into the workpiece 4 to be processed more efficiently and conveniently.

[0033] Among them, the third matching plate 51 is located on the left and right sides of the compression spring 2 and is respectively rotatably installed with a first limiting member 513 and a second limiting member 514. The compression spring 2 is located between the first limiting member 513 and the second limiting member 514. The third matching plate 51 is located on the rotation trajectory of the first limiting member 513 and is provided with a first limiting column 515. The third matching plate 51 is located on the rotation trajectory of the second limiting member 514 and is provided with a second limiting column 516. Since the first limiting member 513 and the second limiting member 514 are respectively rotatably installed on the left and right sides of the third matching plate 51, and the compression spring 2 is located Between the first limit member 513 and the second limit member, the compression spring 2 is stably located between the first limit member 513 and the second limit member 514 due to the elastic force of the compression spring 2 itself in the absence of external force and the presence of the first limit column 515 and the second limit column 516. During the downward movement of the second matching plate 53, the push rod 531 of the second matching plate 53 can drive the first limit member 513 to rotate clockwise to the left, and the second limit member 514 to rotate counterclockwise to the right, so that the compression spring 2 is pushed downward by the push rod 531 through the movable groove 511 and falls into the positioning groove 41.

[0034] In addition, the reset assembly 7 includes a spring 71 and a vertical plate 72. The vertical plate 72 is fixedly installed on the workbench 1 by welding or other means and is located on the front side of the mounting seat 3. The spring 71 is compressed and arranged between the mounting seat 3 and the vertical plate 72. Due to the existence of the vertical plate 72 and the spring 71, when the driving member 6 drives the driving plate 521 to drive the mounting seat 3 to move forward, the spring 71 will be compressed by the forward force of the mounting seat 3 and then cooperate with the mounting seat 3 to move forward so that the positioning groove 41 of the workpiece 4 to be processed is aligned with the movable groove 511. When it is necessary to complete the assembly of the compression spring 2, the driving plate 521 moves upward. At this time, the elastic energy of the spring 71 drives the mounting seat 3 to move backward, thereby facilitating the reset of the mounting seat 3.

[0035] Among them, it also includes a guide rod 73 fixedly installed on the vertical plate 72 by welding or other means, the spring 71 is located in the circumference of the guide rod 73, and a sliding groove 32 is provided in the mounting seat 3 corresponding to the guide rod 73. Since the guide rod 73 is fixed to the vertical plate 72 and inserted into the mounting seat 3, when the driving plate 521 moves upward and the elastic force of the spring 71 drives the mounting seat 3 to move backward, the mounting seat 3 can move along the length direction of the guide rod 73. Similarly, when the driving plate 521 moves downward and drives the mounting seat 3 to move forward, the degree to which the guide rod 73 is inserted into the sliding groove 32 continues to increase to cooperate with the movement of the mounting seat 3. Therefore, the setting of the guide rod 73 can provide a guiding effect for the forward and backward sliding of the mounting seat 3.
