Description

Technical Field

[0001] This utility model belongs to the technical field of functional components of CNC machine tools, and specifically relates to a locking device for a programmable tailstock of a CNC machine tool. Background Technology

[0002] A CNC machine tool is an automated device that controls the movement and machining process of the machine tool through digital signals. Its core feature is the precise control of parameters such as tool path and speed through computer programs (such as G-code and M-code), solving the problem of machining complex, precision, and small-batch parts. The programmable tailstock is an important component of the machine tool, mainly used to support the workpiece or install tools during machining. It is usually located above the machine bed, opposite the spindle head, and slides along a guide rail system to engage with the workpiece being machined. The design and function of the programmable tailstock directly affect the machining accuracy and safety.

[0003] With the rapid development of modern industry, various industries are demanding increasingly higher positional accuracy for workpiece clamping on horizontal lathes. The workpieces being clamped are heavy and bulky, and the force of the tailstock clamping plate pressing against the machine bed alone is insufficient to accurately position the tailstock. The weight of the workpiece can easily cause the tailstock to wobble. Existing positioning and locking technologies cannot meet these requirements, resulting in low workpiece clamping efficiency. Therefore, we propose a locking device for a programmable tailstock on CNC machine tools. Utility Model Content

[0004] The purpose of this utility model is to provide a locking device for a programmable tailstock of a CNC machine tool, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a locking device for a programmable tailstock of a CNC machine tool, comprising a tailstock body, a sleeve hole extending along the inner side of the tailstock body, a limit frame fixedly installed on one side of the sleeve hole, a lead screw threaded through the surface of the limit frame, a connecting cylinder rotatably connected to one end of the lead screw, a center point provided at the end of the connecting cylinder, a sliding hole opened on one side surface of the tailstock body, a connecting plate fixedly connected to one side of the connecting cylinder, and fixed frames symmetrically fixedly installed on the upper and lower sides of one side of the tailstock body, a reduction motor fixedly installed at the top of the fixed frames, a bidirectional threaded rod rotatably connected between the fixed frames, the top of the bidirectional threaded rod being fixedly connected to the bottom output end of the reduction motor, and an upper clamping block and a lower clamping block symmetrically rotatably threaded at the upper and lower ends of the surface of the bidirectional threaded rod.

[0006] Preferably, the opposing surfaces of the upper clamping block and the lower clamping block are provided with a first anti-slip texture.

[0007] Preferably, the connecting plate has a second anti-slip texture symmetrically formed on its upper and lower sides, and one side of the connecting plate is located between the upper clamping block and the lower clamping block.

[0008] Preferably, one end of the lead screw extends to the outside of the sleeve hole, and a rotating wheel is fixedly connected to the end.

[0009] Preferably, a handle is fixedly connected to one side surface of the wheel.

[0010] Preferably, a support frame is fixedly connected to the bottom of the tailstock body, a base is fixedly connected to the bottom end of the support frame, and fixing pads are fixedly installed at the four corners of the bottom of the base.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During the adjustment and movement of the tip, the connecting plate on one side will be displaced inside the sliding hole. When the tip is in the appropriate position, the bidirectional threaded rod will be rotated by the operation of the geared motor, so that the upper and lower clamping blocks will move relative to each other, thereby achieving the effect of fixing and clamping the upper and lower surfaces of the connecting plate and improving the locking function of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a locking device for a programmable tailstock of a CNC machine tool, including a tailstock body 4. A sleeve hole 5 is opened along the inner side of the tailstock body 4. A limit frame 6 is fixedly installed on one side of the sleeve hole 5. A lead screw 7 is threaded through the surface of the limit frame 6. A connecting cylinder 8 is rotatably connected to one end of the lead screw 7. A center point 9 is provided at the end of the connecting cylinder 8. A sliding hole 12 is opened on one side of the tailstock body 4. A connecting plate 13 is fixedly connected to one side of the connecting cylinder 8. Fixed frames 14 are symmetrically fixedly installed on the upper and lower sides of one side of the tailstock body 4. A reduction motor 16 is fixedly installed at the top of the fixed frame 14. A bidirectional threaded rod 15 is rotatably connected between the fixed frames 14. The top of the bidirectional threaded rod 15 is fixedly connected to the bottom output end of the reduction motor 16. An upper clamping block 17 and a lower clamping block 18 are symmetrically rotatably threaded at the upper and lower ends of the surface of the bidirectional threaded rod 15.

[0020] Specifically, the upper clamping block 17 and the lower clamping block 18 are both provided with first anti-slip textures 19 on their opposite surfaces.

[0021] Specifically, the upper and lower sides of the connecting plate 13 are symmetrically provided with second anti-slip textures 20. One side of the connecting plate 13 is located between the upper clamping block 17 and the lower clamping block 18. The first anti-slip texture 19 and the second anti-slip texture 20 increase the friction between the upper clamping block 17, the lower clamping block 18, and the connecting plate 13.

[0022] Specifically, one end of the lead screw 7 extends to the outside of the sleeve hole 5, and a rotating wheel 10 is fixedly connected to the end. The rotating wheel 10 facilitates the rotation of the lead screw 7 and allows for quick adjustment of the center point 9.

[0023] Specifically, a handle 11 is fixedly connected to one side surface of the rotary wheel 10, and the handle 11 facilitates the operation and use of the rotary wheel 10.

[0024] Specifically, a support frame 2 is fixedly connected to the bottom of the tail frame 4, and a base 1 is fixedly connected to the bottom of the support frame 2. Fixing pads 3 are fixedly installed at the four corners of the bottom of the base 1. The setting of fixing pads 3 increases the overall stability of the device.

[0025] In this embodiment, rotating the handle 11 and the wheel 10 can drive the lead screw 7 to rotate. The rotation of the lead screw 7 can drive the connecting cylinder 8 and the tip 9 to move telescopically inside the sleeve hole 5, thereby achieving the effect of fixing the object. During the movement of the connecting cylinder 8, it will drive the connecting plate 13 on one side to move inside the sliding hole 12. When the tip 9 is in a suitable position, the operation of the reduction motor 16 can drive the bidirectional threaded rod 15 to rotate. The rotation of the bidirectional threaded rod 15 can drive the upper clamping block 17 and the lower clamping block 18 at both ends of the surface to move relative to each other and move in opposite directions. When the upper clamping block 17 and the lower clamping block 18 move relative to each other, they can fix and clamp the upper and lower surfaces of the connecting plate 13, thereby achieving the function of locking the tip 9.
