Description

Technical Field

[0001] The utility model relates to the technical field of machine tool accessories, in particular to a tailstock hydraulic locking structure. Background Art

[0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Drills, reamer drills, reamers, taps, dies and knurling tools can also be used on a lathe for corresponding processing. Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces. They are the most widely used type of machine tools in mechanical manufacturing and repair factories. The tailstock of a machine tool is an important part of the machine tool, and the tailstock body needs to be locked during the use of the machine tool.

[0003] However, the existing tailstock hydraulic locking structure often requires the staff to lock the tailstock body on the guide rail through a manual structure, which is time-consuming and labor-intensive and greatly reduces efficiency.

[0004] Therefore, it is necessary to provide a tailstock hydraulic locking structure to solve the above technical problems. Utility Model Content

[0005] In order to solve the technical problems that the process of locking the tailstock with the existing tailstock hydraulic locking structure is relatively time-consuming and labor-intensive and the working efficiency is low, the utility model provides a tailstock hydraulic locking structure.

[0006] The tailstock hydraulic locking structure provided by the utility model comprises: a tailstock body; a cylinder cover, which is arranged on the tailstock body; a piston rod, which is arranged on the bottom of the cylinder cover; and a pressure plate, which is sleeved on the piston rod.

[0007] Preferably, a plurality of round nuts are threadedly sleeved on the piston rod.

[0008] Preferably, an oil inlet and an oil outlet are provided on the tailstock body.

[0009] Preferably, two guide rails are provided at the bottom of the pressing plate.

[0010] Compared with the related art, the tailstock hydraulic locking structure provided by the utility model has the following beneficial effects:

[0011] The utility model provides a tailstock hydraulic locking structure, which drives a pressure plate to move upward by a piston rod so that the pressure plate can press the lower surface of a guide rail, thereby locking the tailstock body. Through this structure, the locking and loosening of the tailstock body can be transformed from manual to automatic, which greatly improves efficiency and saves time for manual operation. The pressure plate can be fixed on the piston rod by a plurality of round nuts, and the structure can be connected to a hydraulic oil station by hydraulic oil through an oil inlet and an oil outlet, so that a machine tool PLC can control the hydraulic station to inject oil into the cylinder by the hydraulic oil station to push the piston rod to drive the pressure plate to move up and down, and the two guide rails can not only support and guide the tailstock body, but also cooperate with this structure to lock the tailstock body.

[0015] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0016] Please refer to Figure 1-2 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of the tailstock hydraulic locking structure provided by the utility model; Figure 2 for Figure 1 Schematic diagram of the assembly structure of the pressure plate and the guide rail. The tailstock hydraulic locking structure includes: a tailstock body 1; a cylinder cover 2, the cylinder cover 2 is arranged on the tailstock body 1; a piston rod 3, the piston rod 3 is arranged at the bottom of the cylinder cover 2; a pressure plate 4, the pressure plate 4 is sleeved on the piston rod 3, and the pressure plate 4 is driven by the piston rod 3 to move upward so that the pressure plate 4 can press the lower surface of the guide rail 8, thereby locking the tailstock body 1. Through this structure, the locking and loosening of the tailstock body 1 can be transformed from manual to automatic, which greatly improves efficiency and saves time for manual operation.

[0017] The piston rod 3 is threadedly sleeved with a plurality of round nuts 5 , and the pressure plate 4 can be fixed on the piston rod 3 by the plurality of round nuts 5 .

[0018] The tailstock body 1 is provided with an oil inlet 6 and an oil outlet 7, through which the structure can be connected to the hydraulic oil station through hydraulic oil, so that the machine tool PLC can control the hydraulic station to fill the cylinder with oil, push the piston rod 3 and drive the pressure plate 4 to move up and down.

[0019] Two guide rails 8 are arranged at the bottom of the pressing plate 4 , and the two guide rails 8 can not only support and guide the tailstock body 1 , but also lock the tailstock body 1 in cooperation with the structure.

[0020] The working principle of the tailstock hydraulic locking structure provided by the utility model is as follows:

[0021] Use hydraulic oil pipes to connect the oil inlet 6 and the oil outlet 7 to the hydraulic station. The machine tool PLC controls the hydraulic station to fill the cylinder with oil, pushes the piston rod 3, and drives the pressing plate 4 to move upward, so that the pressing plate 4 presses the lower surface of the guide rail 8 to lock the tailstock body 1. During assembly, the round nut 5 must be adjusted to ensure that there is a reasonable gap between the pressing plate 4 and the guide rail 8 to ensure the locking and loosening of the pressing plate 4. Through this structure, the locking and loosening of the tailstock body 1 can be transformed from manual to automatic, which greatly improves efficiency and saves time for manual operation.

[0022] Compared with the related art, the tailstock hydraulic locking structure provided by the utility model has the following beneficial effects:

[0023] The utility model provides a tailstock hydraulic locking structure, which drives the pressing plate 4 to move upward through the piston rod 3 so that the pressing plate 4 can press the lower surface of the guide rail 8, thereby locking the tailstock body 1. Through this structure, the locking and loosening of the tailstock body 1 can be transformed from manual to automatic, which greatly improves the efficiency and saves the time of manual operation. The pressing plate 4 can be fixed on the piston rod 3 through a plurality of round nuts 5, and the structure can be connected to the hydraulic oil station through the oil inlet 6 and the oil outlet 7, so that the machine tool PLC can control the hydraulic station to inject oil into the cylinder by the hydraulic oil station to push the piston rod 3 to drive the pressing plate 4 to move up and down.
