Description

Technical Field

[0001] The utility model relates to a special processing fixture for plastic rubber sealing pieces, belonging to the field of sealing piece production equipment. Background Art

[0002] When existing plastic or rubber seals need to be machined, they are usually processed directly by directly installing the tube or bar material on the chuck, which can save some time.

[0003] The prior art discloses a special processing fixture for plastic rubber seals with announcement number CN211162922U, which comprises a fixture body, a placement groove formed on the top of the fixture body, a fixing block formed in the inner cavity of the placement groove, a mounting rod fixedly formed on the bottom of the fixing block, a mounting hole formed in the inner cavity of the placement groove, a fixing nut formed on the bottom end of the mounting rod passing through the mounting hole, clamping plates uniformly formed on the outer side of the fixing block, threaded holes uniformly formed on the outer side of the fixture body, a threaded rod formed in the threaded hole, and one end of the threaded rod being rotatably connected to the clamping plate.

[0004] However, it is difficult to adjust the angle of the clamp body in the prior art. Therefore, after the seal is fixed, if the processing position needs to be changed, the handle assembly needs to be loosened and then re-clamped, which is quite troublesome. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a special processing fixture for plastic rubber seals to solve the problem.

[0006] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a special processing fixture for plastic rubber seals, including a fixture body and a handle assembly; the handle assembly is arranged around the fixture body, and the handle assembly clamps and fixes the seal; the bottom of the fixture body has a rotating shaft; the rotating shaft is rotatably connected to the base; a limiting structure is provided on one side of the rotating shaft; the limiting structure includes a gear ring arranged on the rotating shaft, a wrench frame hinged on the base, and a tooth block arranged on the wrench frame; the tooth block is clamped into the gear ring to fix the rotating shaft and the base.

[0007] Preferably, a torsion spring is provided at the hinge between the wrench frame and the base; the torsion spring acts on the wrench frame to make the wrench frame close to the base.

[0008] Preferably, a groove for placing the wrench holder is reserved on the base.

[0009] Preferably, the wrench holder is angled; one end of the wrench holder is inclined outward.

[0010] Preferably, the top of the clamp body has a handle.

[0011] Preferably, the rotating shaft is rotatably connected to the base via a bearing.

[0012] Beneficial effects

[0013] The utility model provides a rotating shaft at the bottom of the clamp body and a rotating connection design with the base, so that the clamp body can be easily rotated, thereby changing the position of the seal fixed thereon, improving processing flexibility, avoiding the tedious steps of re-clamping the seal when the processing position needs to be changed in traditional clamps, and significantly improving processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Other features, objects and advantages of the present invention will become more apparent from the detailed description of the non-limiting embodiments with reference to the following drawings:

[0017] Figure 3 It is a structural diagram of the prior art. DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1 、 Figure 2 The utility model provides a technical solution for a special processing fixture for plastic rubber seals: comprising a fixture body 1 and a handle assembly 2; the handle assembly 2 is arranged around the fixture body 1; wherein the position of the clamping block inside the handle assembly 2 is adjusted by the existing handle assembly 2 to clamp and fix the seal on the fixture body 1;

[0020] Furthermore, the bottom of the clamp body 1 has a rotating shaft 3; the rotating shaft 3 is rotatably connected to the base 4. Through the establishment of the rotating shaft 3 and the base 4, the angle of the clamp body 1 can be rotated after clamping, thereby changing the position of the seal in the clamp body 1. Preferably, the top of the clamp body 1 has a handle 11, which can be pulled by hand to facilitate the rotation of the clamp body 1.

[0021] In order to fix the clamp body 1 after rotation and positioning, a limiting structure is provided on one side of the rotating shaft 3; the limiting structure includes a gear ring 31 provided on the rotating shaft 3, a wrench frame 52 hinged on the base 4, and a gear block 51 provided on the wrench frame 52; the gear block 51 is engaged with the gear ring 31 to fix the rotating shaft 3 and the base 4; the gear block 51 is engaged with the gear ring 31 to prevent the rotating shaft 3 from rotating, thereby fixing the clamp body 1.

[0022] Furthermore, a wrench frame 53 is provided at the hinge between the wrench frame 52 and the base 4; the wrench frame 53 acts on the wrench frame 52 to make the wrench frame 52 close to the base 4; so that in the absence of other external forces, the tooth block 51 is in the state of the gear ring 31.

[0023] The wrench frame 52 is angled, with one end of the wrench frame 52 tilted outwards, making it easier for workers to pull the wrench frame 52 .

[0024] The base 4 is provided with a groove 41 for placing the wrench frame 52 , which is used to place the wrench frame 52 and limit the wrench frame 52 so that the tooth block 51 always corresponds to the gear ring 31 .

[0025] Working principle: The worker places the seal on the clamp body 1 and uses the existing handle assembly 2 to fix the seal, and then pulls the wrench frame 52 to disengage the tooth block 51 from the tooth ring 31, so that the clamp body 1 can be rotated. After the rotation angle is determined, the wrench frame 52 is released to allow the tooth block 51 to be engaged with the tooth ring 31, so that the clamp body 1 is fixed.

[0026] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
