Main components include a lens barrel and a lens. The lens barrel is a structure for carrying the lens. Generally, the lens barrel is formed by die casting processing. After processing, the inner and outer walls of the lens barrel need to be polished to remove dimensional tolerances and surface porosity defects and the like.

[0055] A method of using a grinding machine for processing the objective lens barrel of a sight includes the following steps:

[0056] S1: The material 102 is conveyed to the top of the material 102 through the conveying mechanism of the conveying table 300;

[0057] S2: The motor 203 starts to compress the liquid inside the hydraulic chamber 204, which drives the inner shaft 200 to rise, lifting and internally supporting the material 102;

[0058] S3: polishing the outer side wall of the material 102;

[0059] S4: the motor 203 reverses to drive the inner shaft 200 to descend and the outer clamping piece 201 to ascend, thereby lifting and externally clamping the material 102;

[0060] S5: polishing the inner side wall of the material 102;

[0061] S6: the motor 203 drives the outer clamping piece 201 and the inner shaft 200 to retract and reset, thereby completing the inner and outer wall polishing process of a group of materials 102.

[0062] The working process of the polishing machine for processing the objective lens barrel of a sighting scope and the use method thereof is as follows:

[0063] During processing, the cylinder 315 is first started to extend, the push block 301 is pushed to move a group of materials 102 on the arc side of the push block 301 towards the inner shaft 200, in this process, the push block 301 compresses the gas inside the sealed cavity 302, so that the gas is compressed into the flow guide pipe 303, further, the gas enters the flow guide pipe 303 to push the sealing block 304 to move, so that the sealing block 304 moves inside the sealing groove 307 until the flow-through groove 305 outlet is inside the leakage groove 306, at this time, the compressed gas inside the flow guide pipe 303 passes through the flow-through between the flow-through groove 305 and the leakage groove 306, enters the arc branch end of the flow guide pipe 303, pushes the limiting block 310 to move, and limits the materials 102 on the arc side of the push block 301, so as to avoid the movement or dumping of the materials 102 during transportation, while the excess gas enters the communication groove 309 through the driving impeller 311 to rotate into the inside of the exhaust pipe 312, and is sprayed out through the air blowing hole 313 to clean the outer side wall of the materials 102, while the rotation of the impeller 311 can drive the rotating wheel 314 to rotate, and the rotating wheel 314 drives the materials 102 to rotate, so as to realize the omnidirectional air blowing cleaning of the outer side wall of the materials 102, which can not only effectively remove the impurities on the surface during storage and transportation, but also avoid scratching the surface of the materials 102 during polishing, and can also avoid the pressure injury of the surface and the clamping error in the subsequent clamping process, it should be noted that the transmission roller is arranged between the material conveying table 300 and the inner shaft 200 on the top of the polishing table 100, which not only reduces friction, but also effectively separates the peeled impurities from the bottom of the materials 102.

[0064] When the pushing block 301 moves the material 102 above the inner shaft 200, if there is already processed material 102 above the inner shaft 200, the processed material 102 is pushed by the pushing block 301, the limiting block 310 and the conveyed material 102, so that the processed material 102 pushes the second stop block 222 away from the material 102 until the group of materials 102 is separated from the clamping of the second stop block 222, and then falls into the chute on the edge of the grinding table 100 for collection. The conveyed material 102 is located above the coaxial line of the inner shaft 200 after the pushing block 301 moves to the limit position. After the pushing block 301 moves to the limit position, the air cylinder 315 stops for a period of time and then resets to the initial position. In this process, because there is a spring between the sealing block 304 and the flow guide pipe 303, after the gas inside the sealing cavity 302 is continuously supplied to the exhaust groove 306 after stopping compression, the gas inside the sealing cavity 302 is discharged through the small one-way valve on the side wall of the feeding table 300, so that the sealing block 304 resets and is separated from the exhaust groove 308. The compressed gas inside the circular arc branch end of the flow guide pipe 303 is quickly discharged through the exhaust groove 308, so that the limiting block 310 quickly resets and is separated from the restraint of the material 102, so that the pushing block 301 resets without affecting the material 102, and the pushing block 301 resets alone.

[0065] The material 102 affected by the pushing block 301 and the limiting block 310 is reset under the action of the second stop block 222, so that the position of the material 102 is fine-tuned and guided, and the material 102 and the inner shaft 200 and the outer clamping piece 201 approach the coaxial line.

[0066] Further, the motor 203 is started to rotate in the forward direction, driving the threaded shaft 205 to rotate, further driving the threaded piston 206 to move towards the pipe 1 210 through the threaded transmission, compressing the liquid in the hydraulic chamber 204 close to the side of the pipe 1 210, pumping the hydraulic oil into the inner driving cavity 209 through the pipe 1 210, pushing the inner shaft 200 to rise, and during the rising of the inner shaft 200, because the spring lengths of the supporting block 1 214 and the supporting block 215 connected with the inner shaft 200 are different, when the supporting block 1 214 passes the grinding table 100, it can be stretched out under the action of the elastic force, at this time the supporting block 215 is still inside the inner shaft 200, when passing the material 102, the supporting block 1 214 can support and synchronously lift the material 102 through the L-shaped edge, and at the same time, the valve block 216 limits the speed of the hydraulic oil flowing into the driving pipe 1 213, so that when the inner shaft 200 rises to the highest position, the liquid continues to flow to gradually increase the pressure in the driving pipe 1 213 to push the supporting block 215 and the supporting block 1 214 to stretch out to continue to support the bottom of the material 102 and uniformly support the inside of the material 102 to realize internal support and fixation, further control the grinding head 101 to grind the outer side wall of the material 102 in all directions, it should be noted that the internal uniform support and fixation can not only provide stable support force, but also does not interfere with the overall grinding of the outer side wall, without grinding obstacles and blind areas, and because the position of the inner shaft 200 stretched out each time is fixed, the supporting block 1 214 supports and supports the bottom of the material 102, so that the support and lifting position of the inner shaft 200 to the material 102 is consistent each time, which can reduce the calibration time of the grinding head 101.

[0067] After the grinding of the outer side wall of the material 102 is completed, the motor 203 is controlled to reverse, the threaded shaft 205 is reversed, driving the threaded piston 206 to move towards the pipe 2 211, at this time, referring to the above working process, the inner shaft 200 is first lowered and reset through the negative pressure in the inner driving cavity 209, the material 102 is placed on the top of the grinding table 100, the pressure in the outer driving cavity 212 is further increased to push the outer clamping piece 201 to rise, the outer clamping piece 201 first lifts the material 102 through the stretching of the supporting block 2 219 to move to the highest position, and then the clamping block 220 and the supporting block 2 219 are slowly stretched out to clamp the outer side wall of the material 102 through the valve block assembly, the inner side wall of the material 102 is ground by the grinding head 101, after the grinding is completed, the motor 203 is rotated to the initial position of the threaded piston 206, at this time the inner shaft 200 and the outer clamping piece 201 are retracted into the grinding table 100 to realize reset.

[0068] When the push block 301 is reset to the initial position during the circulation process, the group of materials 102 at the lowest part of the inside of the feeding groove 400 slides down through the round groove at the bottom of the feeding groove 400 to the side surface of the push block 301 in cooperation with the arc edge of the push block 301, and meanwhile the remaining materials 102 in the inside of the feeding groove 400 automatically move down to fill the vacancy under the action of gravity, and automatically move down in the next reset cycle of the push block 301, so as to realize automatic feeding and discharging.

[0069] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
