Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spare part processing auxiliary equipment especially relates to a positioning tool for automobile spare parts. BACKGROUND

[0002] With the continuous expansion of global automobile industry, the production demand of automobile spare parts presents explosive growth. The pursuit of automobile quality, performance and diversification of consumers promotes automobile manufacturers to constantly update and change the speed of vehicle model, which directly leads to the increasing variety of automobile spare parts, and the shape, size and structural complexity of automobile spare parts are constantly rising.

[0003] Many existing positioning tools have poor universality, low positioning accuracy and difficulty in adapting to different shape and size spare parts. Some traditional positioning tools adopt fixed clamp structure, which can only clamp specific size spare parts. When different size spare parts need to be processed, the whole tool must be replaced, which will increase the downtime in production process, reduce the overall utilization rate of production equipment, slow down the production progress and affect the production efficiency. Therefore, we propose a positioning tool for automobile spare parts to solve this problem. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a positioning tool for automobile spare parts to solve the problems in the above background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A positioning tool for automobile spare parts, comprising: a frame, a drive motor is fixedly installed at the bottom of the frame, a bevel gear one is fixedly installed on the output end of the drive motor, two groups of supports are fixedly installed on the inner wall of the bottom of the frame, a screw rod is rotatably installed between the inner wall of one side corresponding to the frame in the two groups of supports, a bevel gear two is fixedly installed at one end of the two groups of screw rods, a moving seat is slidingly installed on the outer side of the two groups of screw rods, the two groups of moving seats are slidingly installed on the top of the frame, a distance adjusting assembly is arranged on the top of the two groups of moving seats, the distance adjusting assembly comprises: a connecting seat, two groups of moving blocks and a micro motor, a bidirectional screw rod is rotatably installed in the inner part of the connecting seat, the two groups of moving blocks are threadedly connected on the outer side of the bidirectional screw rod, a clamp is fixedly installed on one side of the two groups of moving blocks, the micro motor is fixedly installed on one side corresponding to the connecting seat, one end of the bidirectional screw rod is fixedly installed on the output end of the corresponding micro motor, and the two groups of moving blocks on the same side are slidingly installed in the corresponding connecting seat.

[0007] Preferably, four sets of sliding cylinders are fixedly installed at the bottom of the frame, and sliding seats are fixedly installed on the outer side of each of the four sets of sliding cylinders. Support seats are fixedly installed at the bottom of each of the four sets of sliding seats, and four sets of dampers and four sets of buffer springs are fixedly installed between the four sets of support seats and the bottom of the frame.

[0008] Preferably, the first bevel gear meshes with two sets of second bevel gears, the two sets of second bevel gears are in opposite directions, and the two sets of screws have the same helical direction.

[0009] Preferably, the top of the frame is provided with two sets of T-slots, and the two sets of movable seats are slidably installed in the corresponding T-slots.

[0010] Preferably, each of the two sets of connecting seats has a slide rail on one side, and the two sets of moving blocks located on the same side are slidably installed in the corresponding slide rail.

[0011] Preferably, the four sets of buffer springs are sleeved and installed on the outside of the corresponding dampers, and the four sets of dampers and the corresponding buffer springs are arranged inside the corresponding slide cylinder and slide seat.

[0012] In this utility model, a positioning fixture for automotive parts is provided. By setting a damper and a buffer spring, the vibration generated during the use of the positioning fixture for automotive parts is reduced. Through the cooperation between the slide cylinder and the slide seat, the displacement of the frame during vibration is guided, so that the frame can still maintain a predetermined position and direction when subjected to vibration, ensuring that the positioning accuracy of automotive parts is not affected. This can reduce the mutual friction and collision between parts caused by vibration, reduce the wear of parts, extend the service life of the fixture, reduce the frequency of maintenance and replacement of the fixture, and reduce production costs.

[0013] This utility model features a reasonable structural design. Two sets of micro motors drive corresponding bidirectional lead screws to rotate, which in turn transmits two sets of moving blocks to move relative to each other under the constraint of the slide rail and connecting seat. This allows for adjustment of the distance between adjacent clamping units. Furthermore, a drive motor drives a first bevel gear to rotate. The first bevel gear meshes with two sets of second bevel gears, causing the second bevel gears to rotate relative to each other. Through the cooperation between the screw and the moving seat, and the T-slot restricting the movement of the moving seats, the two sets of moving seats move relative to each other, thereby driving the corresponding distance adjustment components to clamp and fix the automotive parts. This design is adaptable to various automotive parts of different sizes. Whether small precision parts or large structural components, the tooling can be flexibly adjusted to achieve precise positioning and clamping, greatly improving the tooling's versatility and reducing the cost and time of frequent tooling changes due to changes in part size.

[0023] In this embodiment, bevel gear 3 meshes with two sets of bevel gears 6, the two sets of bevel gears 6 are in opposite directions, and the two sets of screws 5 have the same helical direction, ensuring the straightness and positional accuracy of the moving seat 7 during the movement process, thereby ensuring the clamping accuracy and stability of the adjusting assembly 8 for the automotive parts.
