Embodiment 1

[0032] The drilling processing device for thin-walled annular parts 5 includes a two-way flat-nose pliers body 1, and the two-way flat-nose pliers body 1 includes a jaw seat 103. The jaw seat 103 is provided with two oppositely arranged jaws 102 and drives the two jaws. The handle 101 for bidirectional translation of the mouth 102 also includes a clamping mechanism installed on the two jaws 102 respectively, a support mechanism installed on the clamping mechanism, and a positioning punching mechanism installed on the jaw seat 103; The top of the positioning punching mechanism is provided with a positioning hole 402 therethrough, and the positioning hole 402 corresponds to the center point of the supporting mechanism.

[0033] working principle:

[0034] Using the principle that the jaws 102 of the two-way pliers can simultaneously approach or move away from each other at equal distances, an improvement is made to make a drilling processing device that can be used to clamp thin...

Embodiment 2

[0045] On the basis of Example 1, the drilling spacer 301 in the present invention is further improved.

[0046] Further, it can also be considered in this embodiment that the top surface of the drilling spacer 301 is an arc surface.

[0047] In this embodiment, the diameter of the arc surface of the drilling spacer 301 is the same as the inner diameter of the part 5, and its width is slightly smaller than the width of the part 5, so as to ensure that there is no gap in the drilling position after the part 5 is clamped. When drilling, the arc surface of the drilling spacer 301 can buffer the pressure on the wall surface of the part 5 during drilling, and the part 5 will slightly move the unloading force left and right to make it not deformed.

Embodiment 3

[0049] On the basis of Example 1, the upper bracket 4 in the present invention is further improved.

[0050] Further, it can also be considered in this embodiment that the width of the upper bracket 4 is the same as the width of the top of the side bracket 2 . In this embodiment, the same width makes the structure more stable, beautiful and easy to maintain. In summary, the present invention provides a drilling processing device for thin-walled annular parts.

Abstract

The invention discloses a drilling device for thin-wall annular parts, which comprises a two-way flat tongs body, the two-way flat tongs body comprises a jaw seat, the jaw seat is provided with two oppositely arranged jaws and a handle for driving the two jaws to translate in two directions, and the two jaws are provided with two clamping grooves. The clamping mechanisms are respectively arranged on the two jaws, the supporting mechanisms are arranged on the clamping mechanisms, and the positioning and punching mechanism is arranged on the jaw seat; a through positioning hole is formed in the top of the positioning punching mechanism and corresponds to the center point of the supporting mechanism. The side supports, the upper support and the pressing plate are designed according to the characteristic that the bidirectional flat tongs can achieve bidirectional equal-distance and high-precision clamping, the part is pressed on the bidirectional flat tongs, the purpose of high-precision symmetrical clamping of the thin-wall annular part is achieved, and therefore the position precision of part drilling and the surface quality of the part are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of processing fixtures, in particular to a drilling processing device for thin-walled annular parts. Background technique [0002] For the drilling of thin-walled annular parts, it is necessary to drill millimeter-level small holes on annular parts with a wall thickness of only 1mm, and the small holes are required to be in the center of the annular parts, and the accuracy should not exceed 0.1mm. [0003] The original processing method is to draw a line on the surface of the part to determine the drilling position, but this method cannot guarantee the positional accuracy of the hole, and it is easy to cause scratches on the surface of the part during the marking process, and the processing efficiency is low. Therefore, designing a special drilling processing device to meet the design requirements and improve the processing efficiency under the premise of ensuring the drilling accuracy of the parts and the s...
