The purpose of the utility model can be realized by the following technical proposal:

the pneumatic tailstock is characterized in that the tailstock comprises a base body and a controller, the base body is arranged on the sliding rail, one side, facing the carriage, of the base body is connected with a sensor, a driving piece and a rod-shaped linkage piece, a concave linkage opening is formed in a position, corresponding to the position of the linkage piece, of the carriage, the sensor can detect that the carriage is close to the base body along the Y-axis direction and send a sensing signal to the controller, and the controller can send a control signal to the driving piece so as to drive the linkage piece to stretch into the linkage opening and enable the carriage and the base body to form positioning in the X-axis direction.

When the position of the pneumatic tailstock needs to be adjusted, the carriage moves along the Y-axis direction and approaches to the pedestal, when the carriage approaches to a set position, the sensor detects the approach of the carriage and sends a signal to the controller, the controller sends a control signal to the driving piece, the driving piece drives the linkage piece to move and stretch into the linkage port, so that the X-axis-direction positioning is formed between the carriage and the pedestal, and the carriage can drive the pedestal to move along the sliding rail in the X-axis direction. In the adjusting process of the position of the seat body, manual adjustment is not needed, and the adjustment is more convenient.

In the above pneumatic tailstock, a protruding contact portion is provided on one side of the carriage facing the base, the sensor is a contact sensor, and the contact portion can contact the contact sensor when the carriage moves along the Y-axis direction. As the name implies, a touch sensor is a sensor that must be touched to send a sensing signal, and is a sensor commonly used in the market at present, and may specifically be a pressure sensor.

In the above pneumatic tailstock, the driving member includes a cylinder, and the linkage member is a piston rod of the cylinder.

In the above pneumatic tailstock, the base body is further fixed with a pneumatic clamper, and the controller can send a control signal to the pneumatic clamper to drive the pneumatic clamper to clamp the slide rail. The pneumatic clamp holder fixed on the seat body clamps the slide rail to realize the positioning of the fixed seat body.

Compared with the prior art, the pneumatic tailstock has the advantages that the structure of the driving piece and the linkage port is matched, so that the pedestal can realize automatic position adjustment along with the carriage, manual operation of workers is not needed, the labor intensity is reduced, and the position adjustment is more convenient.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, the pneumatic tailstock is provided on a table 1 of a machine tool, and the table 1 is further provided with a carriage 2 capable of reciprocating in the X-axis direction and the Y-axis direction and a slide rail 3 provided in the X-axis direction.

The pneumatic tailstock comprises a seat body 4 and a controller, wherein the seat body 4 is arranged on a slide rail 3 and can move back and forth along the slide rail 3, one side of the seat body 4, which faces a carriage 2, is connected with a sensor, a driving piece 5 and a rod-shaped linkage piece 6, and a concave linkage port 7 is arranged at the position, corresponding to the linkage piece 6, on the carriage 2.

The sensor can detect that the carriage 2 is close to the seat body 4 along the Y-axis direction and send a sensing signal to the controller, and the controller can send a control signal to the driving part 5 to drive the linkage part 6 to extend into the linkage port 7 and enable the carriage 2 and the seat body 4 to form positioning in the X-axis direction.

In the present embodiment, the carriage 2 is a cross carriage 2 commonly used in a machine tool at present, and the movement in the X-axis direction and the Y-axis direction is realized by two guide rails respectively arranged along the X-axis direction and the Y-axis direction.

Specifically, a fixing plate made of a metal material is fixedly connected to one side of the carriage 2 facing the seat body 4, the lower edge of the fixing plate is bent towards the seat body 4 to form a convex contact portion, the sensor is a contact sensor, and when the carriage 2 approaches towards the seat body 4, the contact portion can be in contact with the contact sensor. A positioning block is fixedly connected to one side of the fixing plate facing the seat body 4, and a groove is formed in one side of the positioning block facing the seat body 4 along the Z-axis direction to form the linkage port 7.

In this embodiment, the driving member 5 comprises a cylinder, and the linkage member 6 is a piston rod of the cylinder; the controller can specifically adopt a common singlechip or a PLC chip and the like on the current market according to the requirement.
