Problems solved by technology

The disadvantage is that the operation is cumbersome and the parts are difficult to process
In addition, the locking direction of the nose end is opposite to the locking direction of the rear end, and the locking can ensure a certain support effect for the rear end, but the pre-tightening of the spindle on the machine box is actually partially offset, resulting in a reduction in the tightening effect

Abstract

The invention discloses an adjustable main shaft locking device, which comprises a positioning sleeve, a pressure adjustment assembly and an actuating piston. The positioning sleeve can fix the main shaft and is provided with a pressure adjustment through hole. The pressure adjustment assembly and the actuating piston pass through the pressure adjustment through hole respectively. The two ends of the pressure regulating assembly are threadedly connected with the pressure regulating through hole. The invention also discloses a lathe spindle box structure, including a spindle, a machine box, and the above-mentioned adjustable spindle locking device. Body, and then the pressure adjustment assembly is screwed in and out in the pressure adjustment through hole, so that the execution piston can be moved away from or close to the end surface of the machine box body, so as to adjust the pressure exerted by the execution piston on the end surface of the machine box body , and then can adjust the connection stiffness between the main shaft and the machine box. The invention can realize effective fixation and pressure adjustment of the main shaft and the machine table, and ensure the connection rigidity and connection precision of the main shaft and the machine table.

Description

technical field [0001] The invention relates to lathe spindle equipment, in particular to an adjustable spindle locking device and a lathe spindle box structure. Background technique [0002] The connection between the spindle and the machine box generally adopts the nose flange connection and the rear-end auxiliary connection to realize the effective fixation of the spindle and the machine box, to ensure the connection rigidity to avoid the impact of the connection on the spindle precision and machining accuracy, and to pursue the best fit. Good processing accuracy, control vibration caused by poor connection, etc. In order to achieve the above purpose, take the lathe spindle as an example, the nose end is connected by flange, and the spindle is fixed on the machine box by screw locking. [0003] The rear end is fastened in the following three forms: [0004] 1. The lock nut is tightened, and the lock nut can provide a tension of tens of thousands of cattle through the sp...
