Problems solved by technology

[0009] The clamping force of the four-jaw chuck is large, but it is time-consuming to align, so it is suitable for clamping large workpieces with irregular shapes.
The three-jaw chuck is automatically centered, and it does not take a long time to find the correct parts. The clamping efficiency is higher than that of the four-jaw chuck, but the clamping force is not as large as the four-jaw chuck.
It is suitable for the work that requires high clamping precision, can only be processed well after multiple clamping, and the work with many processes

Embodiment Construction

[0030] like figure 1 As shown, the lathe four-jaw clamp and three-jaw clamping system mainly includes a lathe, the lathe 1 is connected with a four-jaw chuck 2 , and the end of the four-jaw chuck 2 far away from the lathe 1 is connected with a three-jaw chuck 3 .

[0031] The end of the four-jaw chuck 2 away from the lathe 1 is provided with at least four clamping jaws 21 .

[0032] The clamping claws 21 are evenly distributed on the circumference of the four-jaw chuck 2 and clamped to the body of the three-jaw chuck 3 .

[0033] The side wall of the four-jaw chuck 2 is provided with tightening screws 22 , and the tightening screws 22 are connected with the clamping jaws 21 .

[0034] The end of the three-jaw chuck 3 away from the four-jaw chuck 2 is provided with at least three holding jaws 31 .

[0035] The side wall of the three-jaw chuck 3 is provided with fastening screws 32 , and the fastening screws 32 are connected with the holding claws 31 .

[0036] The four-jaw c...

Abstract

The invention discloses a four-claw clamp and three-claw clamping system for a lathe, which mainly includes a lathe. The lathe is connected with a four-claw chuck, and the end of the four-claw chuck is connected with a three-claw chuck. Compared with the prior art, the present invention has the following advantages and beneficial effects: stable and reliable clamping force can be provided; the cumbersome process of disassembling and installing the four-jaw chuck is eliminated, and production input cost is saved.

Description

technical field [0001] The invention relates to a clamping device of a lathe, in particular to a four-claw clamp and three-claw clamping system of a lathe. Background technique [0002] In the clamping device of lathe, four-jaw chuck and three-jaw chuck are often used. [0003] The three-jaw chuck is composed of a chuck body, movable jaws and jaw driving mechanism. Under the guide part of the three claws on the three-jaw chuck, there are threads that mesh with the plane threads on the back of the bevel gear. When the small bevel gear is turned with a wrench through the square hole, the bevel gear rotates, and the plane threads on the back simultaneously Drive the three jaws to approach or withdraw from the center to clamp workpieces with different diameters. Replace the three claws with three reverse claws to install workpieces with larger diameters. The self-centering accuracy of the three-jaw chuck is 0.05-0.15mm. The accuracy of machining parts with a three-jaw chuck ...
