Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and in particular relates to a clamping tool for an automobile brake pipe. Background Art

[0002] Automobile brake pipes are parts used in automobile brake systems. Their main function is to transfer brake media during automobile braking to ensure that the braking force is transmitted to the automobile brake shoe or brake caliper to generate braking force. When processing or testing automobile brake pipes, clamping tools are usually required for assistance;

[0003] Most of the existing clamping tools are used to clamp the outer wall of the brake pipe. Since the brake pipe is a hollow structure, when clamping the outer wall, if the force is too large, deformation may occur, thereby affecting the processing or detection accuracy of the brake pipe. Utility Model Content

[0004] In view of this, the utility model provides a clamping tool for an automobile brake pipe, which is used to solve the technical problem that the brake pipe has a hollow structure and may be deformed when its outer wall is clamped if the force is too large.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a clamping tool for an automobile brake pipe, comprising a processing table, wherein the upper surface of the processing table is symmetrically provided with two movable grooves, wherein the movable grooves are respectively slidably connected with support rods, the two support rods are in the shape of the letter "L" and are mirror-set, and the top opposite ends of the support rods are both provided with clamping components;

[0007] The clamping assembly comprises a center disk fixedly mounted on the support rod, a plurality of fixed cylinders are fixedly mounted on the outer circumference of the center disk at equal intervals, and a limit plate is fixedly connected to the inner wall of the fixed cylinder at one end away from the center disk;

[0008] The inner wall of the fixed cylinder is slidably connected with a slider, and a first screw rod is fixedly installed on the slider. The first screw rod extends in a direction away from the center disk. The first screw rod passes through the limiting plate and an inner abutment plate is fixedly installed on the end thereof. A raised arc surface is provided on the side of the inner abutment plate away from the center disk.

[0009] On the basis of the above technical solution, the clamping tool for a vehicle brake pipe of the utility model can also be improved as follows:

[0010] Furthermore, an inner adjustment block is threadedly connected to the surface of the first screw rod, and the inner adjustment block is rotatably connected to a side of the limiting plate away from the center disk.

[0011] Furthermore, one end of the connecting plate is fixedly mounted on the inner abutment plate, a connecting seat is fixedly mounted on the other end of the connecting plate, an outer abutment plate is slidably connected to the connecting plate, and a concave arc surface is provided on one side of the outer abutment plate away from the connecting seat.

[0012] Furthermore, one end of a second screw rod is fixedly mounted on the outer abutment plate, the second screw rod extends in a direction away from the center disk and passes through the connecting seat, and an outer adjustment block is threadedly connected to the surface of the second screw rod, and the outer adjustment block is rotatably connected to the connecting seat.

[0013] Furthermore, one end of the movable groove is rotatably connected to a transverse screw rod, and the transverse screw rod passes through the support rod and is threadedly connected thereto.

[0014] Furthermore, a driving motor is fixedly mounted on the other end of the movable groove, and an output shaft of the driving motor is fixedly connected to the transverse screw rod.

[0015] Compared with the prior art, the clamping tool for automobile brake pipe provided by the utility model has the following beneficial effects:

[0016] By setting an inner abutment plate, the clamping of the outer wall of the brake pipe is changed to abutment support of the inner wall, so as to prevent the outer wall from being squeezed inward and causing deformation of the brake pipe. An outer abutment plate is further provided to assist in abutment clamping of the outer wall of the brake pipe, and the inner abutment plate corresponds to the outer abutment plate in position, so as to further prevent deformation of the brake pipe. The abutment of the inner and outer walls of the brake pipe can prevent the rotation of the brake pipe.

[0017] By arranging the fixing cylinders installed at equal distances, the inner abutment plates and the outer abutment plates are also arranged at equal distances, and this arrangement makes the brake pipe bear force evenly;

[0018] By setting a first screw rod, an inner adjustment block, etc., the inner abutment plate is adjusted according to the inner diameter of the brake pipe, and by setting a second screw rod, an outer adjustment block, etc., the outer abutment plate is adjusted according to the outer diameter of the brake pipe. The inner abutment plate and the outer abutment plate can be adjusted separately, so that the clamping tool is suitable for brake pipes of various sizes. BRIEF DESCRIPTION OF THE DRAWINGS
