Description

Technical Field

[0001] The utility model relates to the technical field of lead screws, in particular to an automatic lead screw grinding device. Background Art

[0002] A lead screw is a mechanical transmission element that is primarily used to convert rotational motion into linear motion, or vice versa. Lead screws can be divided into three categories based on their friction characteristics: sliding lead screws, rolling lead screws, and hydrostatic lead screws. Lead screws play a core role in modern mechanical manufacturing and industrial automation, and are widely used in various devices that require precise motion control.

[0003] However, after heat treatment (a technique that changes the internal structure and properties of metal materials through heating and cooling to ensure long-term stable working conditions under high loads and precision motion conditions, thereby improving the reliability and service life of the overall mechanical system), some impurities will appear on the surface of the lead screw. In order to facilitate the subsequent processing of the lead screw, it is necessary to polish and remove the impurities on the surface of the heat-treated lead screw. However, there is no good polishing device for existing lead screws. It is inconvenient and laborious for workers to polish with a handheld wire drawing machine. At the same time, the device has difficulty in properly clamping lead screws of different models, resulting in certain limitations in the use of the device. Utility Model Content

[0004] The main purpose of the utility model is to provide an automatic screw grinding device, which can effectively solve the problems of inconvenience in clamping the screw during grinding and the time-consuming and labor-intensive grinding process.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A screw automatic grinding device includes a support frame and a fixed base, wherein a No. 1 mounting seat is installed on the left upper end of the support frame, a No. 1 mounting frame is installed on the upper end of the No. 1 mounting seat, a No. 2 mounting seat is installed on the right upper end of the support frame, a No. 2 mounting frame is installed on the upper end of the No. 2 mounting seat, and a six-axis robot is installed on the upper end of the fixed base.

[0007] Preferably, a clamping hydraulic cylinder is fixedly installed on the left end of the No. 1 mounting frame, a piston rod is fixedly installed on the output end of the clamping hydraulic cylinder, a pneumatic chuck is installed on the left end of the No. 2 mounting frame, a servo motor is installed on the upper right end of the No. 2 mounting frame, a cylinder is installed on the lower right end of the No. 2 mounting frame, and a lead screw is installed between the pneumatic chuck and the piston rod. One side of the lead screw is inserted into the pneumatic chuck, and the pneumatic chuck and the cylinder are pneumatically connected. The cylinder moves, thereby driving the pneumatic chuck to clamp one side of the inserted lead screw. Then, the clamping hydraulic cylinder drives the piston rod at its output end to push to the right, thereby clamping the other side of the lead screw. Not only can the lead screw be clamped and limited quickly, but the device can also clamp lead screws of different models.

[0008] Preferably, a wire drawing machine is mounted on the lower end of the six-axis robot, a soft wire drawing wheel is mounted inside the wire drawing machine, and a dust collection interface is mounted on the lower end of the wire drawing machine. The six-axis robot can drive the wire drawing machine to adjust its position left and right and up and down, so that the soft wire drawing wheel can grind the outer surface of the lead screw. In addition, a dust collection interface is also provided on the lower end of the wire drawing machine, which can be connected to an external dust collector to prevent dust from being dispersed during grinding by the soft wire drawing wheel.

[0009] Preferably, the piston rod and the pneumatic chuck are positioned correspondingly on the left and right.

[0010] Preferably, the pneumatic chuck and the cylinder are pneumatically connected.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. When impurities on the outer surface of the lead screw are polished and removed after heat treatment, first connect the external power supply to the six-axis robot, clamping hydraulic cylinder, servo motor, wire drawing machine and other equipment that need to be connected to the power supply, then insert one side of the lead screw into the pneumatic chuck, and the pneumatic chuck and the cylinder are pneumatically connected. The cylinder moves, thereby driving the pneumatic chuck to clamp one side of the inserted lead screw. Then, the clamping hydraulic cylinder drives the piston rod at its output end to the right to clamp the other side of the lead screw. Not only can the lead screw be clamped and limited quickly, but the device can also clamp lead screws of different models, thereby improving the applicability of the device.

[0013] 2. After the screw is clamped, the wire drawing machine is started, which in turn drives the soft wire drawing wheel to rotate. Then, the six-axis robot can drive the wire drawing machine to adjust the position left and right and up and down, so that the soft wire drawing wheel can grind the outer surface of the screw. In addition, a dust suction interface is provided at the lower end of the wire drawing machine, which can be connected to an external vacuum cleaner to avoid dust from floating when the soft wire drawing wheel is grinding, further improving the practicality of the device.
