technical field

The invention relates to a special fixture for a lathe, which belongs to a mechanical positioning device and is mainly used for clamping and positioning parts on a lathe.

Background technique

In lathe fixtures, general-purpose fixtures such as three-jaw chucks are often used. For non-rotating bodies or parts with complex structures, three-jaw chucks cannot guarantee the positioning accuracy and repeat positioning accuracy of the parts.

Contents of the invention

In order to better realize the technical scope and reasonable application of the lathe, the present invention provides a lathe fixture for machining the transverse hole of the differential. Through the connection between the front section of the main shaft of the lathe and the special fixture, the differential parts are positioned on the special fixture to complete the differential parts. The machining of the horizontal inner hole guarantees the coaxiality of the transverse inner hole of the differential, and completes the machining content of all the inner holes on the same axis in one clamping. The processing efficiency is improved, the fixture occupies a small space, and the use is safe and reliable.

The technical solution of the present invention is: a kind of differential gear transverse hole machining fixture for machining the transverse inner hole of the differential gear on the lathe, including connecting plate, clamp body, positioning pin, pressing block, pin, compression spring, locking Nuts, screws, pull rods, and a differential. The clamp body is connected to the connecting plate through screws and positioning pins. The clamp body is provided with a radial cylindrical hole. The cylindrical hole and the end of the clamp body face the differential. Accurate positioning, the positioning pin is fixed on the end surface of the clamp body, and the circular rotation of the differential is restricted through the positioning hole on the differential. The pull rod is fitted on the clamp body through the shaft hole, and a pressure block is fixed at one end of the pull rod through a pin , A compression spring is installed on the pull rod cylinder between the pressure block and the clamp body, and the other end of the pull rod is threadedly connected with a lock nut.

In application, a fixture for machining the transverse hole of a differential is connected to the main shaft of the lathe through a connection plate, and the differential is positioned on the fixture body through the inner hole, end face and pin of the fixture, and the lock nut is screwed to make the pressing block compact. The flange end face of the transmission, the differential is positioned and clamped, after the turning process is completed, the lock nut is loosened, the pressure block is away from the end face of the differential under the action of the compression spring, the pressure block is turned, and the differential parts are taken out.

Description of drawings

Accompanying drawing 1 is the structure diagram of a kind of fixture of differential gear transverse hole machining vehicle according to the present invention, accompanying drawing 2 is a side view of a kind of differential gear transverse hole machining fixture of the present invention, and accompanying drawing 3 is the parts diagram of clamp body.

Detailed ways

Referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, the present invention provides a kind of clamping machine for machining the transverse hole of differential gear, including connecting disc 1, clamping body 2, positioning pin 3, pressing block 4, pin 5, compression spring 6 , Lock nut 7, screw 8, positioning pin 9, tie rod 10, differential gear 11.

The clamp body 2 of the differential transverse hole processing vehicle fixture is connected on the connecting plate 1 by screws 8 and positioning pins 9, the clamp body 2 is provided with radial cylindrical holes, and the cylindrical holes of the clamp body 2 and The end faces the differential gear 11 to achieve precise positioning, and the positioning pin 3 is fixed on the end face of the clamp body, and the circular rotation of the differential gear 11 is limited through the positioning holes on the differential gear 11 .

The pull rod 10 of the differential transverse hole machining fixture is fitted on the clamp body 2 through the shaft hole, and one end of the pull rod 10 is fixed with a briquetting block 4 through the pin 5, and the pull rod 10 between the briquetting block 4 and the clamp body 2 A compression spring 6 is installed on the column, and the other end of the pull rod 10 is threadedly connected with a locking nut 7 .

The differential device 11 of the clamp for processing the transverse hole of the differential device is positioned on the clamp body 2 through the inner hole of the clamp, the end surface and the pin, and the lock nut 7 is screwed, so that the pressure block 4 is pressed against the differential device 11 The end face of the flange and the differential 11 are positioned and clamped. After the turning process is completed, the lock nut 7 is loosened, and the pressure block 4 is moved away from the end face of the differential under the action of the compression spring 6. Turn the pressure block 4 and the differential 11 The parts are taken out.
