Description

Technical Field

[0001] The utility model relates to the technical field of a driven tailstock, in particular to a flexible driven tailstock for a slant bed linear rail CNC lathe. Background Art

[0002] Referring to the patent document with application number "CN202222152337.7", entitled "A CNC lathe tailstock mechanism", this patent document drives the lead screw through the adjustment mechanism, so that the lead screw and the slider move in coordination, and the slider slides on the guide rail to achieve longitudinal and lateral adjustment of the tailstock of the lathe. It is driven by a motor, which is convenient for workers to operate, and has high adjustment accuracy, thereby improving the workers' work efficiency.

[0003] The prior art uses an ejector pin to support the tail of the workpiece so that the workpiece will not be displaced during the machining process. Although the ejector pin can effectively reduce the displacement of the workpiece, the ejector pins will push each other when contacting the workpiece, which will cause the longitudinal lead screw of the ejector pin to deform, making the lead screw deformed and unable to adjust longitudinally normally. In addition, the ejector pin will also shrink backwards when hit, causing damage to its longitudinal slider, thereby reducing the service life of the ejector pin.

[0004] Therefore, we designed a flexible drive tailstock for a slant bed linear rail CNC lathe. Utility Model Content

[0005] The utility model aims to solve the problem that the service life of the ejector pin is reduced in the prior art and provides a flexible drive tailstock for a slant bed linear rail CNC lathe.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A flexible drive tailstock for an inclined bed linear rail CNC lathe comprises a lathe tailstock, a bin body is provided on the lathe tailstock, a striker for pressing a workpiece is provided on the bin body, a support plate for raising the bin body is provided on the bin body, a threaded rod for adjusting the height of the striker is provided in the bin body, a control body for limiting the striker is provided on the threaded rod, compression springs for buffering the impact of the striker are symmetrically provided on the control body, a limiting rod for moving the striker is provided on the bin body, a fixed block is provided on the bin body, and a compression shaft for buffering the threaded rod is provided on the fixed block.

[0008] Preferably, the control body is matched with the threaded rod, the control body is fixedly connected to the striker via a telescopic joint, and a long hole for longitudinal adjustment of the striker is provided on the warehouse body.

[0009] Preferably, the telescopic joint is symmetrically provided with sliding grooves, the control body is symmetrically provided with sub-control bodies, the sub-control bodies are provided with connecting rods, one end of the compression spring is fixed to the sliding groove, and the other end is against the connecting rod.

[0010] Preferably, a motor for driving is provided on the control body, one end of the motor slides on the limiting rod through a slider, and a groove is provided on the limiting rod.

[0011] Preferably, the fixing block is fixedly connected to the warehouse body by welding, a connecting hole is provided on the warehouse body, and the threaded rod is adapted to the connecting hole.

[0012] Preferably, one end of the compression shaft is fixedly connected to a fixing block, and the other end of the compression shaft is provided with a limiting block for limiting the threaded rod.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model reduces the deformation of the threaded rod caused by the impact force generated when the striker hits the workpiece through the arrangement of the compression shaft and the limiting block. On the contrary, when the threaded rod moves backward, the displacement force will be reduced by the compression shaft, so that the impact force of the striker reduces the damage to the threaded rod. The limiting block can prevent the threaded rod from deviating to both sides, thereby preventing the striker from causing scratches to the workpiece and increasing the service life of the striker.

[0015] 2. The utility model reduces the impact force generated when the striker hits the workpiece by setting a compression spring. The compression spring can effectively reduce the damage of the impact force to the control body and prevent the motor from being deformed due to the impact force, which increases the subsequent maintenance cost.

[0024] A control body 6 for limiting the striker 3 is provided on the threaded rod 5. The control body 6 is used to stabilize the striker 3 so that the lateral angle of the striker 3 is in a horizontal state and remains fixed on the threaded rod 5. The control body 6 is adapted to the threaded rod 5. A threaded hole is provided on the control body 6 for longitudinal movement on the threaded rod 5. The control body 6 is fixedly connected to the striker 3 through a telescopic joint. The telescopic joint is a prior art, and is composed of a plurality of segments of different lengths and similar specifications, so as to realize lateral adjustment of the striker 3. A long hole is provided on the warehouse body 2 for longitudinal adjustment of the striker 3. The long hole is provided on one side of the warehouse body 2 and is mainly convenient for longitudinal adjustment of the striker 3.

[0025] The control body 6 is symmetrically provided with a compression spring 63 for buffering the impact of the striker 3. The compression spring 63 is used to absorb the impact of the striker 3 and alleviate the damage to the control body 6. The telescopic joint is symmetrically provided with a slide groove, which is a space for the compression spring 63 to be arranged. The control body 6 is symmetrically provided with a sub-control body 61, which is used to disperse the impact. The sub-control body 61 is provided with a connecting rod 62, which is L-shaped and is used to connect the compression spring 63. One end of the compression spring 63 is fixed to the slide groove, and the other end is against the connecting rod 62. The front end of the compression spring 63 is against the side wall of the connecting rod 62, so that the impact of the telescopic joint can be transmitted to the sub-control body 61.

[0026] A limiting rod 8 for the movement of the striker 3 is provided on the warehouse body 2, and the limiting rod 8 is used to limit the moving trajectory of the motor 7.
