Technical Field

[0001] This utility model relates to the field of tailstock technology, specifically a tailstock mechanism with a brake. Background Technology

[0002] The tailstock, also known as the tail support or rear ejector pin, is an important component of machine tools such as lathes and grinding machines. It is usually installed at the other end of the machine bed (opposite to the spindle box) and is mainly used to support and fix the workpiece to ensure the stability and accuracy of the machining process.

[0003] Most existing tailstock mechanism devices do not have lateral movement function during use, and the lateral accuracy is difficult to guarantee after long-term operation. The problem is mostly solved by the equipment testing and maintenance personnel regularly checking and correcting the accuracy. This solution is highly dependent on manual labor, requires high assembly and debugging skills from the equipment testing and maintenance personnel, and has high maintenance costs. In addition, existing tailstock mechanism devices also have the problem of low temperature resistance of the clamping plate during use, which leads to a low actual service life of the clamping plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This tailstock mechanism with brake, through the coordinated use of the upper and lower tailstock bodies, and by adding an automatic locking clamp and position sensor between the upper and lower tailstock bodies, achieves automatic locking after the tailstock moves to the designated position with accurate and reliable positioning. This reduces manual intervention, increases the automation level of the equipment, realizes full closed-loop control of the tailstock, and improves the equipment's accuracy and accuracy retention capability.

[0013] 2. The tailstock mechanism with brake uses a clamping plate body made of high-strength alloy steel, which has significantly improved tensile strength compared to ordinary steel.
