Description

Novel anti-scraper

Technical Field

The utility model relates to the field of machining, especially, relate to a novel anti-scraper.

Background

In the field of machining, shape machining such as reverse hole machining, face machining, chamfering and the like is often performed in the machining process, and if a forward tool is used, problems such as insufficient tool length and tool interference occur, or the tool cannot be fed after being completely closed backwards (as shown in fig. 5). The novel reverse scraping tool is mainly two types of first-type and split tools, and a tool bar extends into a workpiece to clamp a tool bit for the second time; two adopt the novel anti-scraper of expansion, can realize the automatic tool changing of CNC lathe, avoid the cost of 2 times operation to improve machining efficiency greatly, but its cutter gets into the part after the closure, and the later stage realizes through lathe positive and negative commentaries on classics that the cutter expandes the closure, and the lathe procedure complicated in this scheme processing, and stability is relatively poor. Based on this, the utility model provides a novel anti-scraper.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel anti-scraper solves the above-mentioned problem.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model relates to a novel reverse scraper, which comprises a main body, wherein a groove is arranged at the front end of the main body, a cutter block is arranged in the groove through a transmission pin shaft, a positioning pit is arranged in the main body, and a cutter block top fixedly connected with the end part of the cutter block is rotatably arranged in the positioning pit; a cooling liquid channel is arranged in the main body, and an outlet of the cooling liquid channel points to the upper part of the cutter block; and a torsion spring is arranged on the transmission pin shaft, one end of the torsion spring is fixedly connected with the transmission pin shaft, and the other end of the torsion spring is fixedly connected with the cutter block.

Further, the angle of the positioning socket is 90 degrees.

Furthermore, the cooling liquid channel is filled with high-pressure cooling liquid.

Furthermore, the transmission pin shaft is in threaded connection with the main body.

Furthermore, the tool block tip and the tool block are of an integrally formed structure.

Compared with the prior art, the utility model discloses a beneficial technological effect:

the utility model discloses a novel anti-scraper passes through transmission pin axle part and is rotatory basic shaft with the 90 degrees location nest in the cutter main part, makes the sword piece expand or closed, is in the processing state during the expansion, can freely come in and go out the parts machining diameter when closing. The knife block is opened through high-pressure cooling liquid, the knife is closed through the pressure of the torsion spring, the main shaft is not required to rotate reversely, the setting and the operation are simple, the practicability is high, and the optimal operation mode is high-efficiency production.

Detailed Description

As shown in fig. 1-4, a novel reverse scraper comprises a main body 2, a groove is arranged at the front end of the main body 2, a cutter block 3 is arranged in the groove through a transmission pin shaft 1, and the transmission pin shaft 1 is in threaded connection with the main body 2. The transmission pin shaft 1 is fixedly connected with the main body 2, so that a gap between the cutter block 3 and the main body 2 can be eliminated. A positioning socket is arranged in the main body 2, and the angle of the positioning socket is 90 degrees. The positioning socket is rotatably provided with a cutter block tip 5 fixedly connected with the end part of the cutter block 3, and the cutter block tip 5 and the cutter block 3 are of an integrally formed structure. The cutter block 3 is unfolded or closed by taking the transmission pin shaft 1 and a 90-degree positioning socket in the main body 2 as a rotating reference shaft.

The inside coolant liquid passageway 6 that is provided with of main part 2, the export of coolant liquid passageway 6 points to the sword piece 3 top. The cooling liquid channel 6 is filled with high-pressure cooling liquid, and the cutter 3 is opened through the high-pressure cooling liquid.

The transmission pin shaft 1 is provided with a torsion spring 4, one end of the torsion spring 4 is fixedly connected with the transmission pin shaft 1, the other end of the torsion spring 4 is fixedly connected with the cutter block 3, and the cutter 3 is closed through the self elasticity of the torsion spring 4.

The action process of the utility model is as follows:

firstly, putting a main body 2 into a shaft hole of a workpiece to be machined; secondly, opening an outlet of the cooling liquid channel 6, and impacting the cutter body by high-pressure cooling liquid to rotate the cutter body by 90 degrees to open the cutter 3; then, the cutter 3 processes the workpiece under the rotation action of the main body 2; and finally, after the machining is finished, closing the outlet of the cooling liquid channel 6, enabling the cutter 3 to rotate 90 degrees under the self elasticity of the torsion spring 4, closing the cutter 3, and pulling the main body 2 out of the shaft hole of the machined part.

The above-mentioned embodiments are only described in the preferred embodiments of the present invention, but not limited to the scope of the present invention, and various modifications and improvements made by the technical solutions of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the design spirit of the present invention.
