Abstract

The utility model discloses a drill bit adjusting mechanism for a pipe burr sharpener. The drill bit adjusting mechanism comprises a grinding head, an inner hole penetrating through the whole grinding head is arranged in the grinding head along the length direction of the grinding head, a pipe inner diameter chamfering drill bit is arranged in the inner hole in a penetrating mode, an internal thread is arranged in the inner hole at the rear end of the grinding head, an adjusting screw is positioned at the rear end of the grinding head, and the adjusting screw is screwed into the inner hole and abuts against the rear end of the pipe inner diameter chamfering drill bit. The drill bit adjusting mechanism is that the adjusting screw is positioned at the rear end of the grinding head, the adjusting screw abuts against the rear end of the drill bit, inlet and outlet of the pipe inner diameter chamfering drill bit can be adjusted finely, and the best effect of internal-external chamfering can be guaranteed.

Description

The drill bit governor motion that is used for pipe burr sharpener

Technical field

The utility model relates to a kind of pipe burr sharpener, particularly a kind of drill bit governor motion for pipe burr sharpener.

Background technology

Pipe endoporus and cylindrical in cutting process leave certain burr, and be very complicated in the past pipe two ends deburring, will grind off burr on the pipe cylindrical at abrasive machine first; Then, bore at drill bit with holding pipe at bench drill, remove the burr in the endoporus, so both do not had operating efficiency, dangerous again.

Just extremely be necessary so research and develop a kind of inside and outside beveler of two-way pipe that can automatically removing burr, but all parts that forms beveler all needs careful design; Such as directly contact with pipe and carry out deburring for pipe burr sharpener, in bistrique, to be provided with endoporus, be provided with the ips chmfer bit in endoporus, the ips chmfer bit is directly to insert in the pipe inner tube is carried out grinding when work, breaks away from pipe after work is finished again; But find in the practice, drill bit contracts too inward, and in the time of removing the inner tube burr, the outer tube chamfering is too large has fallen unfavorable welding to tube wall thin; Drill bit stretch out then easily inner tube is fallen too much thin be unfavorable for equally the welding.

The utility model content

The utility model has overcome above-mentioned the deficiencies in the prior art, and a kind of governor motion that can finely tune drill bit advance and retreat is provided, regulate the drill bit extension elongation according to the processing needs after, position again and get final product.

The technical solution of the utility model is achieved in that

A kind of drill bit governor motion for pipe burr sharpener, comprise bistrique, in bistrique, be provided with the endoporus that runs through whole bistrique along the bistrique length direction, in endoporus, be equipped with the ips chmfer bit, be provided with internal thread in the endoporus of bistrique rear end, be provided with set screw in the bistrique rear end, described set screw screws in endoporus and ips chmfer bit rear end offsets.

The turnover of ips chmfer bit can be finely tuned like this, can guarantee like this optimum efficiency of inside and outside chamfering.

Adopted the beneficial effects of the utility model of technique scheme to be:

Drill bit governor motion of the present utility model is in the bistrique rear end set screw to be set, and set screw and drill bit rear end offset, thereby so that the turnover of ips chmfer bit can be finely tuned, can guarantee like this optimum efficiency of inside and outside chamfering.

Description of drawings

Fig. 1 is the structural representation of the utility model drill bit governor motion.

The specific embodiment

The specific embodiment of the present utility model is as follows:

Embodiment: a kind of drill bit governor motion for pipe burr sharpener, as shown in Figure 1, comprise bistrique 22, at the bistrique 22 interior endoporus 23 that run through whole bistrique that are provided with along bistrique 22 length directions, in endoporus 23, be equipped with ips chmfer bit 26, be provided with internal thread in the endoporus of bistrique 22 rear ends, be provided with set screw 28 in the bistrique rear end, described set screw 28 screws in endoporus and ips chmfer bit 26 rear ends offset.

Claims

1. drill bit governor motion that is used for pipe burr sharpener, it is characterized in that: comprise bistrique, in bistrique, be provided with the endoporus that runs through whole bistrique along the bistrique length direction, in endoporus, be equipped with the ips chmfer bit, be provided with internal thread in the endoporus of bistrique rear end, be provided with set screw in the bistrique rear end, described set screw screws in endoporus and ips chmfer bit rear end offsets.
