Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive frame torsion spring assembly technology, specifically to an automotive seat frame torsion spring assembly fixture. Background Technology
[0002] This automotive seat frame torsion spring assembly fixture assists in assembling torsion springs onto the automotive seat frame, reducing the time and difficulty of manual assembly and thus significantly improving assembly efficiency. Through precise design, the fixture ensures that the torsion springs can be accurately and securely installed on the seat frame.
[0003] According to the patent application CN 214604147U, "An assembly tooling for a torsion spring of an automotive seat frame is described as follows: "An assembly tooling for a torsion spring of an automotive seat frame includes a connecting rod. A connecting horizontal plate is fixedly connected to the top of the connecting rod. A locking mechanism is provided on the connecting horizontal plate. Two sets of connecting rods are provided on the top of the connecting horizontal plate. Locking blocks are fixedly installed on the adjacent side walls of the two sets of connecting rods. A pull handle is fixedly connected to the bottom of the connecting rod. A magnetic block is fixedly connected to the bottom of the pull handle."
[0004] Regarding the above description, the applicant believes the following issues exist:
[0005] In use, this utility model involves rotating a hand-held knob, which in turn rotates a rotating rod and a bidirectional threaded rod. The bidirectional threaded rod then moves two sets of sliding blocks, which in turn move two sets of connecting rods and locking blocks. When the two sets of locking blocks come into contact, the hand-held pull handle is used to pull them. However, in actual use, when the device uses the bidirectional threaded rod to clamp the torsion spring on both sides, the operator needs to repeatedly rotate the bidirectional threaded rod to move the locking blocks relative to each other and clamp the torsion spring. Furthermore, during disassembly, the bidirectional threaded rod must be rotated in the opposite direction repeatedly to release the torsion spring. This increases the workload for the operator, making the entire clamping process time-consuming and further reducing work efficiency. Consequently, it is inconvenient to quickly clamp the torsion spring. Therefore, an improved assembly tool for automotive seat frame torsion springs is needed. Utility Model Content
[0006] The purpose of this utility model is to provide an assembly tooling for torsion springs of automotive seat frames to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a torsion spring assembly fixture for an automobile seat frame, including a handle, a connecting sleeve fixedly connected to the top of the handle, a connecting plate fixedly connected to the top of the connecting sleeve, a clamping and fixing mechanism provided on the top of the connecting plate, and a limit mechanism provided on the inner side of the clamping and fixing mechanism;
[0008] The clamping fixing mechanism comprises a clamping assembly and a fixing assembly, the fixing assembly is arranged at the bottom of the clamping assembly, and the clamping of the pulled torsional spring is facilitated.
[0009] Preferably, the clamping assembly comprises a sliding column fixedly connected to the top of the connecting plate, a sliding block slidingly connected to the outside of the sliding column, a support frame fixedly connected to the top of the sliding block, a clamping block groove fixedly connected to the inner side of the support frame, a connecting rod rotatably connected to the bottom of the support frame, and a pull rod rotatably connected to the end of the connecting rod away from the support frame, so as to facilitate the synchronous clamping of the clamping block grooves on both sides.
[0010] Preferably, the number of the connecting rods and the support frames is two respectively, and the connecting rods and the support frames are symmetrically distributed on the left and right sides of the sliding column with the front surface of the pull rod as the axis, so as to facilitate the pulling of the connecting rods on both sides.
[0011] Preferably, the fixing assembly comprises a fixing sleeve fixedly connected to the front surface of the handle, an inclined block slidingly connected to the inside of the fixing sleeve, a pull plate fixedly connected to the left side of the inclined block, a first spring fixedly connected between the inclined block and the fixing sleeve, a pull column slidingly connected to the inside of the handle, and a limiting sleeve fixedly connected to the bottom of the handle, so as to facilitate the quick fixing of the clamping block groove after clamping.
[0012] Preferably, a groove is formed in the left side of the limiting sleeve, the size of the inclined block is consistent with the size of the groove, the pull rod is fixedly connected to the top of the pull column, a through hole is formed in the corresponding position of the connecting sleeve, and the pull rod passes through the hole, so as to facilitate the quick release of the fixing of the clamping block groove in the later period.
[0013] Preferably, the limiting mechanism comprises a positioning column slidingly connected to the inside of the clamping block groove, a pressing plate fixedly connected to the inner side of the positioning column, a sliding rod fixedly connected to the outside of the pressing plate, a second spring fixedly connected between the pressing plate and the clamping block groove, and a flexible rubber pad fixedly connected to the inner side of the pressing plate, so as to wrap the torsional spring connecting part with the flexible rubber pad, thereby preventing the connecting part from being damaged.
[0014] Preferably, a groove is formed in the corresponding position of the sliding rod and the clamping block groove, and the sliding rod is slidingly connected in the groove, so as to make the flexible rubber pads on both sides fit the torsional spring.
[0015] Compared with the prior art, the automobile seat framework torsional spring assembly tool has the following beneficial effects:
[0016] This automotive seat frame torsion spring assembly fixture, through a clamping and fixing mechanism, moves the clamping block slot to the torsion spring clamping position. Then, by pulling the limiting sleeve, its inclined block is inserted into the slot opened on the left side of the limiting sleeve, thereby fixing the position of the clamping block slot. This further speeds up the worker's fixation of the torsion spring and facilitates the speed of subsequent fixation and removal. It simplifies the tedious work of workers in the fixation and removal process, thereby improving work efficiency and facilitating the quick completion of fixing and removing the torsion spring.
[0017] The automotive seat frame torsion spring assembly fixture, through a limiting mechanism, allows the flexible rubber block to move along the positioning post guide under the elastic force of the second spring. This causes the second springs on both sides to drive the pressure plate to push the flexible rubber pad to wrap around the torsion spring part at the connection. As a result, during the subsequent pulling process, the flexible rubber pad can protect the connection position of the torsion spring and prevent damage. Attached Figure Description
