Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a drilling and tapping device for processing mechanical parts. Background Art

[0002] The tapping machine is a common drilling and tapping equipment. It is a machine tool that uses a tap to process internal threads. It is widely used and indispensable in the field of mechanical parts processing. When the internal threads of mechanical parts are processed by the tapping machine, the mechanical parts are fixed on the clamping fixture, and the position of the drilling and tapping is changed by adjusting the position of the clamping fixture.

[0003] The tapping machines commonly used on the market currently have corresponding clamping tools that can only adjust the position in the XY axis direction, and generally cannot adjust the angle of the clamping tool. Therefore, it is impossible to process internal threaded holes with a certain inclination angle to the surface on mechanical parts. The drilling and tapping of such inclined internal threaded holes are relatively cumbersome and require the help of additional clamping tools. Such internal threaded holes with inclined angles are not uncommon on mechanical parts. The clamping tools of existing drilling and tapping machines are restricted by angle adjustment, resulting in limited use. It needs to be improved to adapt to actual production and processing needs, and will have great market prospects. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a drilling and tapping device for machining mechanical parts, which is used to solve the problem that the clamping fixtures of the tapping machines commonly used on the market are restricted in use due to the limitation of angle adjustment.

[0008] Preferably, a supporting angle plate fixedly connected to the outer wall of the fixing seat is fixedly connected below the left-right flip fixing axis.

[0009] Preferably, positioning flat grooves are equidistantly arranged circumferentially at positions corresponding to the locking handle on the left - right flipping fixed shaft.

[0010] Preferably, the locking handle is an L - type quick - release handle.

[0011] Preferably, mutually meshing positioning tooth grooves are arranged on the opposite surfaces of the front - rear flipping connecting seat and the left - right flipping connecting seat, and the positioning tooth grooves are radially arranged with the front - rear flipping fixed shaft as the center.

[0012] Preferably, the locking nut is a plum - blossom quick - release nut.

[0013] Preferably, two adjusting handles are fixedly connected to the bottom of the clamping tooling main body.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-4 shown, the present utility model provides a technical solution: a drilling and tapping device for machining mechanical parts, including a tapping machine main body 1. A fixed seat 2 is fixedly installed on the column 101 of the tapping machine main body 1. A left - right flipping fixed shaft 3 is horizontally and fixedly connected to the front of the fixed seat 2. Below the left - right flipping fixed shaft 3, a support angle plate 10 fixedly connected to the outer wall of the fixed seat 2 is fixedly connected.

[0023] The surface of the left - right flipping fixed shaft 3 is movably sleeved with a left - right flipping connecting seat 4. At a position near the back on the left - right flipping connecting seat 4, a locking handle 5 with an end supported on the left - right flipping fixed shaft 3 is vertically thread - connected. At a position corresponding to the locking handle 5 on the left - right flipping fixed shaft 3, positioning flat grooves 301 are circumferentially and equidistantly arranged. The locking handle 5 is an L - type quick - release handle.

[0024] At a position near the front of the left - right flipping connecting seat 4, a front - rear flipping fixed shaft 6 perpendicular to the left - right flipping fixed shaft 3 is fixedly connected. A front - rear flipping connecting seat 7 movably clamped outside the left - right flipping connecting seat 4 is rotatably connected to the front - rear flipping fixed shaft 6. Threaded connections are made on both ends of the surface of the front - rear flipping fixed shaft 6 with locking nuts 8 supported on the side surfaces of the front - rear flipping connecting seat 7.

[0025] Positioning tooth grooves 471 that mesh with each other are arranged on the opposite surfaces of the front - rear flipping connecting seat 7 and the left - right flipping connecting seat 4. The positioning tooth grooves 471 are radially arranged with the front - rear flipping fixed shaft 6 as the center. The locking nut 8 is a plum - blossom quick - release nut. The top of the front - rear flipping connecting seat 7 is fixedly connected to a clamping tooling main body 9. Two adjusting handles 11 are fixedly connected to the bottom of the clamping tooling main body 9.

[0026] Working principle: Fix the mechanical part by clamping it with the main body 9 of the clamping tooling. The left and right flipping connecting seat 4 rotates left and right around the left and right flipping fixed shaft 3 to adjust the angle. Tighten the locking handle 5 against the positioning flat groove 301 to lock the left and right flipping angle. The front and back flipping connecting seat 7 rotates back and forth around the front and back flipping fixed shaft 6. Lock the front and back flipping angle with the locking nut 8, so that the main body 9 of the clamping tooling can be tilted at multiple angles in the front, back, left, and right directions. The mechanical part clamped by the main body 9 of the clamping tooling can not only change its position in the front, back, left, and right directions, but also tilt and change its angle in the front, back, left, and right directions, so as to complete drilling and tapping at different positions and drilling and tapping at different tilting angles.
