specific Embodiment approach 1

[0008] Specific implementation mode one: combine Figure 1 to Figure 14 Describe this embodiment, a kind of thin-walled conical body window drilling special fixture of this embodiment includes a fixture base 1, a first support frame 2, a second support frame 5, an end face positioning block 9, a drilling template 12, a positioning body 13, A plurality of positioning wheels 6 and a plurality of positioning shafts 7, the end face positioning block 9, the first support frame 2 and the second support frame 5 are sequentially fixed on the fixture base 1 from left to right, and the height of the first support frame 2 is low At the height of the second support frame 5, each positioning wheel 6 is respectively installed on the upper end of the first support frame 2 and the upper end of the second support frame 5 through a positioning shaft 7, and the positioning body 13 is installed on the positioning wheel 6, The positioning body 13 is a positioning body with unequal cross-sectional ...

specific Embodiment approach 2

[0009] Specific implementation mode two: combination figure 1 , figure 2 , Figure 7 , Figure 8 Illustrate this embodiment, a kind of thin-walled conical body window drilling special fixture of this embodiment also includes washer 3, positioning hole 22 and nut 4, the upper end two sides of first support frame 2 and the upper end two sides of second support frame 5 Both sides are provided with two positioning holes 22, the positioning shaft 7 passes through the positioning hole 22 and the positioning wheel 6 and is connected and fixed by the nut 4, and the gap between the nut 4 and the first support frame 2 and the second support frame 5 is respectively sleeved with a washer 3 . In this way, the nut 4 and the washer 3 of this embodiment fix the positioning wheel 6 to prevent the positioning shaft 7 and the positioning wheel 6 from falling off. Other connection modes are the same as those in Embodiment 1.

specific Embodiment approach 3

[0010] Specific implementation mode three: combination figure 1 , figure 2 , Figure 9 to Figure 14 Describe this embodiment, the positioning body 13 of a kind of thin-walled cone window drilling special fixture of this embodiment is a cone structure, and the large end of the positioning body 13 is matched with the large end of the tail cone 17, the positioning body The outer cone surface of 13 cooperates with the inner cone surface of tail cone 17, and the upper and lower ends of the positioning body 13 respectively offer a window identical to the shape of the tail cone 17 window to be processed. The window of the tail cone 17 is a tapered body window made up of the first lining strip 18 , the first side strip 19 , the second lining strip 20 and the second side strip 21 . In this way, the cone-shaped structure of the positioning body in this embodiment ensures that it fits closely with the tail cone of the processed part, has support for the processed part, and reduces pro...

Abstract

The invention relates to a clamp for hole drilling, in particular to a clamp special for hole drilling of a thin-wall conic body window. The problems that in the machining process, an existing thin-wall conic body part is prone to deformation, positioning for hole drilling of a thin-wall conic body is difficult, and the machining efficiency is low are solved. According to the clamp, an end face positioning block, a first supporting frame and a second supporting frame are fixed to a clamp base, the height of the first supporting frame is smaller than the height of the second supporting frame, and the upper end of the first supporting frame and the upper end of the second supporting frame are each provided with a positioning wheel through positioning shafts; the large end of a positioning body is installed on the positioning wheel installed on the first supporting frame, the small end of the positioning body is installed on the positioning wheel installed on the second supporting frame, the end face of the large end of the positioning body abuts against an end face positioning block, and the positioning body can rotate in the axial direction; and a drill plate is installed on the upper end face of the positioning body and connected with the positioning body in a matched manner. The clamp is used for hole drilling of the thin-wall conic body window.

Description

technical field [0001] The invention relates to a jig for drilling, in particular to a jig specially used for drilling thin-walled cone windows, and belongs to the field of mechanical processing tools. Background technique [0002] In the process of machinery manufacturing industry, a process equipment used to fix the processing object so that it occupies the correct position so as to accept construction is collectively referred to as fixture. In the machining process, fixtures can be divided into general fixtures and special fixtures according to the scope of use. The special fixtures are designed and manufactured for a certain process. The positioning of the thin-walled conical parts should be adjusted. The center line of the drilling should be perpendicular to the conical surface of the conical body, which will bring inconvenience to the drilling and cannot achieve mass production; , will produce complex elastic-plastic deformation, reduce product quality, and process ef...
