Abstract

The invention discloses an adjustable internal thread deburring device, which comprises a screw (1) and is characterized in that: the bottom of the screw rod (1) is provided with a mounting groove (8), a guide blade (2) is arranged in the mounting groove (8), the guide blade (2) is connected with a spring (3), and the other end of the spring (3) is connected with a plug (4). The invention has low requirements on the processing environment such as the appearance of the processed workpiece, the position of the thread and the like, and has strong process operability; the use is convenient, the thread is not easy to scratch, and smooth transition between thread forms is realized. The problem of if screw class part screw in behind the internal thread because the burr jamming can't take out is solved. When the internal thread with the same specification is processed, the influence of the diameter of the bottom hole of the internal thread is avoided, the cutting force of the guide blade can be automatically adjusted by using the adjustable plug and the spring, and the flexibility is high.

Description

Adjustable internal thread deburring device

Technical Field

The invention relates to a technology for removing internal thread tooth type burrs in machining, in particular to an adjustable internal thread deburring device.

Background

In the process of machining internal threads on a workpiece, due to the hole position, the depth and the like, the generated internal thread tooth-shaped burrs are difficult to remove. In particular, when the deep hole or the internal thread of a complex shell is involved, a screw tap or a self-made scraper is generally used by a fitter for processing, when the screw tap is used for processing, the burr removing effect is poor due to the influence of the tolerance of the bottom diameter hole of the internal thread, the thread is easily damaged when the scraper is used for processing, the removing effect is not good, and the processing efficiency is low. If the problem needs to be solved, a tool capable of automatically adjusting in the thread bottom hole is manufactured to remove thread burrs so as to improve the thread machining quality.

Disclosure of Invention

The invention aims to provide an adjustable internal thread deburring device. The thread is convenient to use and not easy to scratch, and the thread is not influenced by the diameter of the bottom hole of the internal thread.

The technical scheme of the invention is as follows: the adjustable internal thread deburring device comprises a screw, wherein a mounting groove is formed in the bottom of the screw, a guide blade is arranged in the mounting groove, the guide blade is connected with a spring, and the other end of the spring is connected with a plug.

In the adjustable internal thread deburring device, the head part of the guide blade is a cutting tool bit, the middle part of the guide blade is a tool body, and the bottom part of the guide blade is a spring connecting column.

According to the adjustable internal thread deburring device, the plug is in threaded connection with the mounting groove.

In the adjustable internal thread deburring device, the screw rod is connected with the clamping rod.

In the adjustable internal thread deburring device, the mounting groove is square.

The invention has the beneficial effects that: compared with the prior art, the device has the following advantages:

1. the requirements on the processing environments such as the appearance of a processed workpiece, the position of a thread and the like are low, and the process operability is strong; the use is convenient, the thread is not easy to scratch, and smooth transition between thread forms is realized. The problem of if screw class part screw in behind the internal thread because the burr jamming can't take out is solved.

2. The device is not influenced by internal thread bottom hole diameter size when processing the internal thread of the same specification, and the application is adjustable end cap and spring and is adjusted the cutting force size of direction blade by oneself, and the flexibility is high. The screw rod can be changed according to the difference of the size of the removed thread, and the screw rod can be replaced to remove the thread by using the device no matter how large the diameter of the thread is.

3. The screw and the guide blade limit the position of the blade, so that the cutter can stably cut along the thread direction, the effect of removing the internal thread tooth type burrs can be achieved, the cutter is convenient to replace, and the service cycle of the whole structure is long;

4. when the device is withdrawn, the cutter is forced to return to the inside of the screw rod, and new burrs or clamping stagnation cannot be generated due to the extrusion of the cutter.

Detailed Description

The invention is further illustrated by the following figures and examples, which are not to be construed as limiting the invention.

Example 1 of the invention: the utility model provides an adjustable internal thread burring device, is including

screw rod

1, and 1 bottom of screw rod is opened there is mounting groove 8, is equipped with direction blade 2 in the mounting groove 8, and direction blade 2 coupling spring 3, end cap 4 is connected to the 3 other ends of spring.

The head of the guide blade 2 is a cutting tool bit 5, the middle of the guide blade is a blade body 6, and the bottom of the guide blade is a spring connecting column 7.

The plug 4 is in threaded connection with the mounting groove 8, the mounting groove 8 is square at one end of the cutting bit 5, and other parts can be round.

The screw rod 1 is connected with a clamping rod 9.

The threaded part of the screw rod 1 is processed according to the actual internal thread size, the clamping rod 9 is a polished rod and can be clamped, the mounting groove 8 is formed in the bottom of the screw rod 1 tooth form, the guide blade 2 is arranged in the mounting groove 8 to limit the cutting tool bit 5 in the form of a square groove, the guide blade 2 is enabled to rotate along the thread, the spring 3 is arranged in the spring connecting column 7 of the guide blade 2, and then the screw-in plug 4 is screwed in. The cutting length of the guide blade 2 can be adjusted by rotating the plug 4, and according to the thread fit clearance, when the screw rod 1 is screwed into the internal thread of the workpiece 10 to be deburred, the cutting tool bit 5 of the guide blade 2 stretches inside the screw rod 1 to achieve the purpose of deburring the internal thread.
