Tooling clamp for processing insulating collar turning and method for processing same

Abstract

The invention discloses a tooling clamp for processing an insulating collar turning. The tooling clamp comprises a concave clamp (8) and a convex clamp (9), wherein the concave clamp (8) comprises a jaw chuck A (10) and a plurality of equant sectorial blocks A (11), the sectorial concave part in each equant sectorial blocks A (11) is composed of a sectorial plane A (13) and a arc-shaped surface side wall A (14), the convex clamp (9) comprises a jaw chuck B (15) and a plurality of equant sectorial blocks B (16), a sectorial plane C (19) is also arranged on the outer side of each equant sectorial block B (16), and the invention further discloses a processing method. The tooling clamp provided by the invention has the advantages that the gripping force is even, so that the deformation of a workpiece is avoided, the clamping efficiency is improved, the time is saved, the workpiece quality and the processing efficiency are improved, and the consistency and the reliability of a part is increased as well.

Description

technical field [0001] The invention relates to the technical field of tooling fixtures, in particular to tooling fixtures for turning insulating rings and a processing method thereof. Background technique [0002] The insulating ring plays a connecting role and connection between the parts, and it also plays a great role in the transmission and connection of its signals and the stability of the signals during its operation. Its structure is as figure 1 As shown, it includes an inner circular surface 1, an outer circular surface 2, a left end surface 3 and a right end surface 4. There is also a groove 5 on the outer circular surface 2. In the previous clamping method, the out-of-roundness far exceeded the design and process requirements. The out-of-roundness reached 0.2-0.3mm, and the parallelism was between 0.05-0.1, which brought some difficulties to the subsequent assembly. The foreseeable bad state, but also because its out-of-roundness is 0.2-0.3m, and the parallelism...

Its structure is as figure 1 As shown, it includes an inner circular surface 1, an outer circular surface 2, a left end surface 3 and a right end surface 4. There is also a groove 5 on the outer circular surface 2. In the previous clamping method, the out-of-roundness far exceeded the design and process requirements. The out-of-roundness reached 0.2-0.3mm, and the parallelism was between 0.05-0.1, which brought some difficulties to the subsequent assembly. The foreseeable bad state, but also because its out-of-roundness is 0.2-0.3m, and the parallelism is between 0.05-0.1, it will cause accumulated axial deviation during assembly, resulting in early wear of each part, and it is also possible Causes inaccurate transmission and connection of the signal of the whole machine

[0003] The existing clamping device 6 for turning the inner circle surface and the left end face, such as figure 2 As shown, the three-jaw chuck comes with three jaws to clamp. Since the width of the three-jaw and the workpiece contact surface is only 20mm, the length is only 13mm, the contact surface with the workpiece is small, and the friction force is also small, so in the process of processing In order to prevent the workpiece from spinning, it is necessary to apply a large clamping force. Because the material is epoxy glass cloth tube, the texture is relatively soft, and at the same time, it is partially stressed, so the workpiece is often deformed after processing.

[0004] The existing clamping device 7 for turning the outer circular surface, the groove and the right end face, such as image 3 As shown, the interference clamping method is adopted, and this kind of interference must also ensure that the inner circle size of the workpiece is less than 0.03mm or more than the outer circle size of the tooling, otherwise it cannot be processed, which improves the accuracy of the clamping device and also improves the processing efficiency. cost

Because the turning process is extrusion cutting, it will form a certain radial force and axial force. Since the size is smaller than 0.03mm, the workpiece cannot be easily clamped to the design position. It must be clamped with external force, and the two ends Whether it fits perfectly depends on the observation and feeling of the operator, and the accuracy is low, because the percussion force of clamping and unloading is not uniform, so the workpiece is deformed again
