Problems solved by technology

[0002] At present, the electric drills on the market can be divided into DC electric drills and AC electric drills according to the current, and can be divided into impact electric drills and electric drills without impact according to whether they have impact. It is composed of female sleeve, bearing, bearing pad, front sleeve and rear sleeve. The three jaws are respectively installed in the three equally divided oblique holes of the drill body. The nut is installed in the nut groove of the drill body. The nut and the jaws The screw thread forms a thread transmission mechanism, the nut sleeve is fixedly connected with the nut, the nut sleeve is connected with the key of the front sleeve, the rear sleeve is fixedly connected with the drill body, and there is a threaded hole or a taper hole at the rear of the drill body; when installing and using, the drill body The threaded hole or taper hole at the rear is connected to the main shaft of the electric drill. The main shaft of the electric drill rotates to drive the drill body to drive the three jaws and the clamped tools to rotate synchronously. However, when encountering some high-intensity work fields, The electric drill without impact function cannot complete the work without the impact function, and the impact electric drill must be replaced. If the user does not have the impact electric drill, the user must re-purchase the impact electric drill to complete the operation, which invisibly increases the burden on the customer and increases the production cost of the customer.

Embodiment 1

[0032] The front and back in this embodiment refer to the direction from the first impact block 8 to the first drill body 7 .

[0033] Depend on Figure 1 ~ Figure 2As shown, the present invention provides a collet with impact function, which includes bearing pad 1, bearing 2, nut 3, nut sleeve 4, front sleeve 5, jaw 6, first drill body 7, three clamps Claws 6 are respectively installed in three equally divided oblique holes of the first drill body 7, nut nuts 3 are installed in nut grooves of the first drill body 7, nut nuts 3 cooperate with the threads of jaws 6, and nut nuts 3 The rotation drives the jaws 6 to stretch out the clamping tool or retract the jaws 6. When clamping the tool, hold and relatively rotate the front sleeve 5 so that the screw nut sleeve 4 connected with the front sleeve 5 drives the screw nut 3 Relative to the rotation of the jaw 6 in the first drill body 7, the jaw 6 moves forward in the inclined hole of the first drill body 7 to clamp the tool thro...

Embodiment 2

[0042] The front and back in this embodiment refer to the direction from the second impact block 27 to the second drill body 26 .

[0043] Depend on Figure 9 , Figure 10 , Figure 14 As shown, the second half of the second drill body 26 included in this embodiment is the same as the second half of the first drill body 7 in Embodiment 1, and the principle of clamping tools is also the same, so it will not be described in detail here. The difference between the embodiment and embodiment 1 is that in this embodiment, the impact device in the present invention includes a second impact block 27, a second sliding sleeve 28, a second shaft sleeve 29, a second elastic body 30, a second thrust Steel ball 31, the second connecting steel ball 32, the inside of the front end of the second drill body 26 is provided with a second shaft end hole 33, the second shaft end hole 33 is provided with a second thrust steel ball 31, the second shaft end hole 33 The end of the second thrust stee...

Abstract

The invention provides a punching type chuck. The punching type chuck solves the technical problem that an existing electric drill without punching function cannot meet the punching function requirement. The punching type chuck achieves the purpose of punching of the electric drill without the punching function, so that the use function of the electric drill without the punching function is increased; and the punching type clamp is widely applicable to the technical field of clamps.

Description

technical field [0001] The invention relates to the technical field of clamps, in particular to a clamp with an impact function. Background technique [0002] At present, the electric drills on the market can be divided into DC electric drills and AC electric drills according to the current, and can be divided into impact electric drills and electric drills without impact according to whether they have impact. It is composed of female sleeve, bearing, bearing pad, front sleeve and rear sleeve. The three jaws are respectively installed in the three equally divided oblique holes of the drill body. The nut is installed in the nut groove of the drill body. The nut and the jaws The screw thread forms a thread transmission mechanism, the nut sleeve is fixedly connected with the nut, the nut sleeve is connected with the key of the front sleeve, the rear sleeve is fixedly connected with the drill body, and there is a threaded hole or a taper hole at the rear of the drill body; when ...
