Problems solved by technology

The present invention overcomes the shortcoming of slow centering speed of drilling and tapping, and has the advantages of simple structure, low manufacturing cost, convenient clamping and loosening operation, fast centering speed, high verticality, reduced loss of drill taps, and guaranteed product quality. However, this fixture can only clamp one part in turn, which is not suitable for large-scale drilling and tapping operations. In addition, due to the huge torque during steel drilling, the present invention cannot guarantee firm fixation

Embodiment 1

[0030] A fixture for drilling and tapping hinged steel, the fixture is used to fix parts 4 to be processed, such as figure 1 As shown, the fixture includes a base 1, a part mounting seat 2 and a pressing mechanism. The part mounting seat 2 and the pressing mechanism are both arranged on the base 1. The pressing mechanism is connected with the part mounting seat 2. positioning mechanism and a plurality of cylindrical positioning pins 21;

[0031] The part 4 to be processed is positioned on the part mounting seat 2 by the cylindrical positioning pin 21 and the side positioning mechanism, and after being pressed and fixed by the pressing mechanism, the part 4 to be processed is drilled and tapped.

[0032] The part 4 to be processed is provided with a positioning hole, which matches the shape of the cylindrical positioning pin 21, so as to complete the front and rear positioning of the part to be processed.

[0033] Such as figure 1 As shown, the side positioning mechanism incl...

Embodiment 2

[0046] In this embodiment, the similarities with the first embodiment will not be described, and only one difference with the embodiment will be described.

[0047] Such as image 3 As shown, among the plurality of elastic ball pressing blocks 23 in this embodiment, the elastic ball pressing blocks 23 distributed on both sides of the component mounting base 2 are provided with grooves 233 only on the side facing the side positioning reference block 22 .

[0048] The pressing mechanism includes a power module, a lever assembly and a briquetting block 31 connected in sequence, and the briquetting block is provided with a plurality of briquetting heads 311 whose positions and numbers are consistent with those of the parts 4 to be processed.

[0049] The power module is a hydraulic pump, and the hydraulic pump is arranged outside the base 1 .

[0050] In this embodiment, there is only one hydraulic pump, and one hydraulic pump provides energy for the pressing action of multiple b...

Abstract

The invention relates to a fixture used for drilling and tapping of hinge shape steel. The fixture is used for fixing to-be-processed parts and comprises a base, a part mounting seat and a pressing mechanism, wherein the part mounting seat and the pressing mechanism are arranged on the base; the pressing mechanism is connected with the part mounting seat; the part mounting seat is provided with a side positioning mechanism and a plurality of cylindrical positioning pins; the to-be-processed parts are positioned on the part mounting seat by the cylindrical positioning pins and the side positioning mechanism; after being pressed and fixed by the pressing mechanism, the to-be-processed parts are drilled and tapped. Compared with the prior art, the fixture has the advantages that the use is convenient, the working efficiency is high, the clamping is firm, and the like.

Description

technical field [0001] The invention relates to a tapping clamp, in particular to a clamp for drilling and tapping hinged steel. Background technique [0002] At present, some fixtures have problems such as convenient clamping parts, unreliable clamping methods, small number of clamping parts at one time, and unstable positioning dimensions in use, which affect production efficiency. [0003] For example, the Chinese patent application number 201310274247.8 discloses a special fixture for drilling and tapping, including a base, a clamping seat, and a fixed clip. The feature is that the clamping seat is provided with a cam frame, the cam is installed in the cam frame through a shaft, and a handle is arranged on the cam. The present invention overcomes the shortcoming of slow centering speed of drilling and tapping, and has the advantages of simple structure, low manufacturing cost, convenient clamping and loosening operation, fast centering speed, high verticality, reduced l...
