Self rotating control device of shaft

Abstract

Provided is a self rotating control device of a shaft. The device uses a self rotating mode of the shaft to conduct location control on the shaft. The self rotating device comprises a shaft 1 and a ring 2 sleeved on the shaft 1, an upper lead 1-1 and a lower lead 1-2 are arranged at one end of the shaft 1, a wave form guiding face is respectively arranged on the upper lead 1-1 and the lower lead 1-2, each wave form guiding face comprises a slope face and a straight groove, a guide groove is formed in a gap between the upper lead and the lower lead, a guide pin shaft 2-1 matched with the guide groove is arranged in a radial direction of the ring 2 which is relatively fixed, and the shaft 1 can slide and rotate in the ring 2. Compared with the prior art, the self rotating control device has the advantages of reducing component which does relative movement, reducing failure rate of the device and greatly reducing work load of maintenance. The self rotating control device is arranged at one end of the shaft, a space on the middle portion of the shaft is left, and the self rotating control device is favorable for allocation of matched device. The self rotating control device can be used for anvil feeding of a forging and pressing machine, a clamp shaft of a clamp device of an upper die and other devices for achieving location control of the shaft.

Description

technical field [0001] The invention relates to the rotational positioning control technology of the shaft in the machine equipment. Background technique [0002] The forging press often needs to replace the upper and lower anvils according to the process requirements. Since the upper anvil is suspended on the movable beam, several clamping devices installed on the movable beam are generally used to complete the replacement of the upper anvil. The devices must allow the suspension shaft or the tightening shaft to realize a period of 90° rotation. In order to reduce the anvil changing time, the original forging press uses such as figure 1 As shown in the rotating device, this device adopts gear rack and gear transmission, which has disadvantages such as complex structure, easy damage, and slow anvil changing speed. [0003] At present, some self-rotating devices improved on the basis of this rotating device have appeared, among which the more advanced one is the self-rotati...

AI Technical Summary

Problems solved by technology

This device simplifies the structure of the original device to a certain extent, and improves the speed of changing the anvil, but still has the following disadvantages: (1) the movement process is complicated, the spring and the moving sleeve, the moving sleeve and four guide ribs, the shaft and the moving sleeve There are mutual movement and collision, which greatly increases the possibility of failure of the whole device; (2) the spring 6 and the moving sleeve 7 are all moving parts, and the teeth of the shaft 5 will collide with the guide edge 8, so the above spring 6. The moving sleeve 7 and the guide edge 8 are all vulnerable parts, and it is difficult to replace the above three parts; (3) Since the teeth of the spring 6, the moving sleeve 7 and the shaft 5 are all arranged in the middle of the shaft 5, Occupies a certain amount of space, making it difficult to arrange auxiliary devices that cooperate with this device

In addition, the core of the device is not to clamp, but to allow the suspension shaft or clamping shaft to rotate at a period of 90°, so the name "self-rotation clamping device" is not accurate enough.
