[0002] In the existing mechanical production, robots can completely replace manual operation, realize the mechanization and automation of production, ensure the personal safety of operators, improve the working environment of operators, reduce the labor intensity of operators, and reduce production costs. Therefore, they are widely used. At present, robots are also widely used in the field of CNC lathes.

[0003] For example, the patent (CN214770718U) discloses an automatic loading and unloading manipulator for CNC lathes, including a mobile mechanical arm, a truss and a lathe, the bottom end of the mobile mechanical arm is fixedly connected with an electric telescopic rod, the telescopic end of the electric telescopic rod is fixedly installed with a motor housing by bolts, the lower surface of the motor housing is fixedly connected with a fixed box, and the inner wall of the fixed box is rotatably connected with a bidirectional screw through a bearing. The automatic loading and unloading manipulator for CNC lathes is provided with a servo motor, a fixed box, a bidirectional screw, a movable connection block, a fixed cross plate, a clamping sleeve, a sliding connection column and a clamping block. The servo motor drives the bidirectional screw to rotate forward and reverse, which can drive the two clamping blocks to squeeze the workpiece with balanced pressure, thereby achieving the effect of stably clamping the workpiece, and then the mobile mechanical arm moves on the truss to transfer the workpiece, replacing the manual loading and unloading method, and the operation is quick and convenient, which improves the processing efficiency of the CNC lathe.

[0004] When using the above technology, we found that the following technical problems exist in the prior art: when the prior art clamps the workpiece, due to the harsh working environment of the machine tool processing, the dust and particles on the surface of the workpiece will cause the electric clamp to detach, thereby causing damage to the workpiece. For this reason, we designed a lathe loading and unloading robot to provide another technical solution to the above technical problems. Utility Model Content

[0005] Based on this, it is necessary to provide a lathe loading and unloading robot to address the above-mentioned technical problems. The robot can be adjusted in multiple directions through the base, telescopic arm, linkage arm and support arm, thereby driving the support block and the electric gripper to clamp the workpiece. The air is blown out from the slide along the duct through the output end of the fan, thereby cleaning the dust on the surface of the workpiece and improving the clamping stability of the electric gripper.

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

[0007] A lathe loading and unloading robot comprises a base, the top of the base is rotatably connected to a support arm, the top of the support arm is rotatably connected to a linkage arm, a telescopic arm is fixed to one end of the linkage arm, a support block is fixed to the output end of the telescopic arm, both sides of the support block are rotatably connected to electric grippers, a fan is fixed to one side of the support arm, a connecting pipe is fixed inside the support block, the output end of the fan is fixedly connected to the connecting pipe through a conduit, and a sliding cylinder is slidably connected to the bottom end of the outer side of the connecting pipe.

[0008] As a preferred embodiment of a lathe loading and unloading robot provided by the utility model, limiting grooves are fixed at both ends inside the support block, and the inner side of the limiting groove is slidably connected to the slide cylinder.

[0009] As a preferred embodiment of a lathe loading and unloading robot provided by the utility model, a limiting ring is fixed to the bottom end of the outer side of the connecting tube, springs are evenly fixed to the top of the limiting ring, and the top of the spring is fixed to the slide cylinder.

[0011] As a preferred implementation of a lathe loading and unloading robot provided by the utility model, an air inlet is fixed to the input end of the fan, and a filter is fixed on the inner side of the air inlet.

[0012] As a preferred embodiment of a lathe loading and unloading robot provided by the utility model, an air blowing port is provided at the bottom end of the slide cylinder.

[0015] At the same time, through the above technical solutions, the utility model has at least the following beneficial effects:

[0016] The utility model provides a lathe loading and unloading robot, which discharges gas from the slide cylinder through the output end of the electric gripper. At this time, the wind resistance blades and the wind resistance cylinder block the gas, and then the blocking force is converted into thrust to slide the slide cylinder, which is convenient for the slide cylinder to clean the workpiece with wind. When the electric gripper is clamped, the fan is turned off. At this time, the elastic force of the spring drives the slide cylinder to reset to the inside of the support block, and then the slide cylinder protrudes out of the inside of the support block, which is beneficial to the cleaning of the workpiece. When the slide cylinder is reset to the inside of the support block, the clamping efficiency of the electric gripper is improved, thereby facilitating the improvement of the practicability of the device.

[0027] Embodiment 1

[0028] Reference Figure 1-Figure 4A lathe loading and unloading manipulator comprises a base 1, the top of the base 1 is rotatably connected to a support arm 12, the top of the support arm 12 is rotatably connected to a linkage arm 2, one end of the linkage arm 2 is fixed to a telescopic arm 3, the output end of the telescopic arm 3 is fixed to a support block 7, both sides of the support block 7 are rotatably connected to electric grippers 4, a fan 5 is fixed to one side of the support arm 12, a connecting pipe 11 is fixed inside the support block 7, the output end of the fan 5 is fixedly connected to the connecting pipe 11 through a conduit, and the bottom end of the outer side of the connecting pipe 11 is slidably connected to a slide cylinder 9,

[0029] The base 1, telescopic arm 3, linkage arm 2 and support arm 12 are adjusted in multiple directions, thereby driving the support block 7 and the electric gripper 4 to grip the workpiece, and the air is blown out from the slide 9 along the conduit through the output end of the fan 5, thereby cleaning the dust on the surface of the workpiece and improving the gripping stability of the electric gripper 4;

[0030] The two ends of the support block 7 are fixed with limiting grooves 8, and the inner side of the limiting grooves 8 is slidably connected with the slide cylinder 9;

[0031] The slide cylinder 9 is limited by the limiting groove 8, so that the slide cylinder 9 can be extended and retracted with the support block 7;

[0032] A limit ring 13 is fixed to the bottom end of the outer side of the connecting tube 11, and springs 14 are evenly fixed to the top of the limit ring 13. The top of the spring 14 is fixed to the slide cylinder 9, and a wind resistance cylinder 10 is fixed to the inner side of the slide cylinder 9. Wind resistance blades 15 are evenly fixed between the wind resistance cylinder 10 and the wind resistance blades 15, and a blowing port is opened at the bottom end of the slide cylinder 9;

[0033] When the electric gripper 4 clamps the workpiece, the air is made to flow out from the blowing port of the slide cylinder 9 along the conduit through the output end of the fan 5, and the design of the wind resistance cylinder 10 and the wind resistance blade 15 blocks the air, so that the wind resistance cylinder 10 and the wind resistance blade 15 block the air and drive the slide cylinder 9 to slide toward the workpiece, thereby compressing the spring 14, so that the slide cylinder 9 can extend out of the support block 7 to clean the workpiece, thereby improving the cleanliness of the workpiece surface;

Since the above-mentioned base 1, linkage arm 2, telescopic arm 3, electric clamp 4, support block 7 and support arm 12 are existing public technologies, they are not elaborated in detail here. When the electric clamp 4 clamps the workpiece, the air is discharged from the blowing port of the slide 9 along the duct through the output end of the fan 5, and the design of the wind resistance cylinder 10 and the wind resistance blade 15 blocks the gas, and then the gas drives the slide 9 to clean the workpiece in the direction of the workpiece, thereby improving the cleanliness of the workpiece surface and improving the stability of the clamping of the electric clamp 4.
