Technical Field
[0001] The utility model relates to the technical field of lathe tailstocks, in particular to a programmable tailstock. Background Art
[0002] The lathe tailstock is a machine tool component on the lathe that is mainly used to cooperate with the spindle to support slender shaft-like workpieces. Usually, the bottom of the programmable tailstock is connected to the ball screw or guide rail seat drive through a sliding seat to enable the programmable tailstock to move.
[0003] The programmable tailstock on the market now drives the tailstock to move through a pneumatic cylinder or an oil cylinder. However, the installation structure of the existing programmable tailstock driven by an oil cylinder is relatively simple, and the oil cylinder is usually directly connected to the sliding seat, resulting in limited movement accuracy of the programmable tailstock.

[0006] The present application provides a programmable tailstock, which includes a tail top box, a slide and a cylinder. The programmable tailstock also includes a locking nut, a cylinder guide positioning inner conical gasket and a cylinder nut seat. The cylinder is fixedly mounted on the bottom end of the slide, one end of the piston rod of the cylinder is connected to the cylinder nut seat, the locking nut is mounted on the outside of the piston rod and is used to lock the cylinder nut seat on the piston rod, the top end surface of the cylinder nut seat is fixedly connected to the tail top box, the bottom end of the cylinder nut seat forms a sliding connection with the top end surface of the slide, the cylinder guide positioning inner conical gasket is fastened and sleeved on the outer end surface of the piston rod of the cylinder, and the cylinder guide positioning inner conical gasket is arranged between the piston rod of the cylinder and the cylinder locking nut seat.
[0007] In a possible implementation manner, linear guide rails are respectively provided on the left and right sides of the top end surface of the slide seat, and sliding blocks slidably matched with the linear guide rails are respectively provided on the left and right sides of the bottom end of the cylinder nut seat.
[0008] In a possible implementation manner, the linear guide rail is fixedly mounted on the top end of the slide seat via a guide rail pressing plate, and the guide rail pressing plate is arranged on the outer side of the linear guide rail.
[0009] In a possible implementation manner, a position sensor is installed at one end of the tail top box.
[0010] In a possible implementation manner, the position sensor is fixedly mounted at one end of the tail top box via a bracket.
[0011] The beneficial effects of the utility model are as follows: by fixing the piston rod end of the cylinder with the cylinder nut seat, and installing a cylinder guide positioning inner conical gasket between the piston rod of the cylinder and the cylinder nut seat, the installation position of the cylinder nut seat on the piston rod of the cylinder is ensured to remain unchanged, and no forward and backward movement along the axial direction of the cylinder is generated, thereby ensuring the synchronous mobility of the cylinder nut seat and the cylinder, thereby improving the movement accuracy of the programmable tailstock.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0019] See attached Figure 1 To Attachment Figure 4 As shown, this embodiment provides a programmable tailstock 100, which includes a tailstock box, a slide 2, a cylinder 9, a locking nut 10, a cylinder guide positioning inner conical gasket 11 and a cylinder nut seat 7.
[0020] Refer to the attached Figure 4As shown, the oil cylinder is fixedly mounted on the bottom end of the slide 2, and the oil cylinder nut seat 7 includes an inverted "L"-shaped connecting end 71. The oil cylinder nut seat 7 is mounted on the piston rod 91 of the oil cylinder 9 through the connecting end 71 thereon, and a locking nut 10 is installed at the outer end surface of the piston rod 91 of the oil cylinder 9. The locking nut 10 is used to lock and install on the outer side of the piston rod 91 of the oil cylinder, that is, it is tightly installed on the outer side surface of the oil cylinder nut seat 7. At the same time, the oil cylinder guide positioning inner conical gasket 11 is installed on the piston rod 91 of the oil cylinder 9, and it is installed between the oil cylinder nut seat 7 and the oil cylinder, so that the locking nut 10 and the oil cylinder guide positioning inner conical gasket 11 are formed on the left and right sides of the connecting end 71 of the oil cylinder nut seat 7, and the two cooperate with each other to limit the installation position of the oil cylinder nut seat 7 on the piston rod 91 of the oil cylinder 9, so as to prevent the oil cylinder nut seat 7 from axially moving on the piston rod 91. This ensures that the installation position of the cylinder nut seat 7 on the piston rod 91 of the cylinder 9 remains unchanged and does not cause forward and backward movement along the axial direction of the cylinder, thereby ensuring the synchronous mobility of the cylinder nut seat 7 and the cylinder, thereby improving the movement accuracy of the programmable tailstock.

Specifically, linear guide rails 3 are respectively arranged on the left and right sides of the top surface of the slide 2, and sliders 8 slidably matched with the linear guide rails 3 are respectively arranged on the left and right sides of the bottom end of the oil cylinder nut seat 7.
[0022] Continue to refer to the attached Figure 1 , Attachment Figure 2 And attached Figure 4 As shown, the linear guide rail 3 is fixedly installed at the top end of the slide 2 through a guide rail pressing plate 4 , and the guide rail pressing plate 4 is arranged on the outside of the linear guide rail 3 .
