Description

Technical Field

[0002] Copper sleeves are bearing sleeves or bushings made of copper or copper alloy, which are widely used in mechanical equipment to reduce friction, improve the wear resistance of equipment and extend service life. Since copper has good thermal conductivity, corrosion resistance, low friction coefficient, high strength and toughness, copper sleeves can operate stably under high load and high temperature environment. The reason why copper sleeves need to be processed is that they have the function of precise matching in the equipment. Through processing, their dimensional accuracy, surface finish and shape tolerance can be guaranteed to ensure close fit with the shaft or other parts, and prevent the gap from being too large to cause unstable operation, or too small to cause assembly difficulties and increased friction.

[0036] After starting the equipment, the first servo motor 7 drives the first screw 6 to rotate, so that the first sliding door frame 5 slides horizontally along the first slide rail 4, and adjusts the alignment of the copper sleeve in the horizontal position; then, the second servo motor 12 drives the second screw 11 to rotate, so that the second sliding door frame 10 slides vertically along the second slide rail 9, and adjusts the precise height position of the copper sleeve; the positioning assembly locks the copper sleeve to ensure that no displacement occurs during the processing; after completing the adjustment and positioning, the processing head 19 starts processing under the drive of the drive motor 18, and at the same time uses the telescopic sleeve 13 to protect the slide rail and screw of the two-way adjustment assembly from dust and debris generated during the processing; after the processing is completed, the first and second servo motors 12 run in reverse respectively to reset the sliding door frame, and the equipment is ready to enter the next processing.

[0037] like Figures 5 to 8As shown, the positioning assembly includes a positioning fixture 20 fixedly installed above the second sliding door frame 10, two limiting sleeves 25 are movably installed inside the positioning fixture 20, a positioning groove 22 is opened on the top circumference of the positioning fixture 20, a plurality of fixed blocks 23 are fixedly installed on the inner side of the positioning groove 22, and a telescopic plate 24 is fixedly installed at the bottom of the fixed block 23, and the telescopic ends of the telescopic plate 24 are fixedly connected to the outer wall of the limiting sleeve 25, and the middle part of the outer wall of the two limiting sleeves 25 is fixedly connected to a plurality of positioning springs 26, and the other end of the plurality of positioning springs 26 It is fixedly connected to the inner wall of the positioning tool 20, and a limiting ring is sleeved on the bottom of the copper sleeve. The limiting ring is inclined at the bottom and arranged horizontally at the top. A fixing ring 33 adapted to the limiting ring is fixedly installed on the upper inner wall of the limiting sleeve 25. The fixing ring 33 is inclined at the top and arranged horizontally at the bottom. A plurality of slide grooves 34 are respectively opened on the inner side of the limiting sleeve 25, and sliding rings 35 consistent with the limiting ring are slidably installed on the plurality of slide grooves 34. A cross-shaped connecting bracket 21 is also fixedly installed at the bottom of the positioning tool 20, and the connecting bracket 21 is used to contact the top of the second sliding door frame 10;

[0038] First, align the lower part of the copper sleeve body with the two limit sleeves 25 in the positioning tool 20. When the copper sleeve body moves downward, the limit ring of the copper sleeve contacts the fixed ring 33. The inclined limit ring and the fixed ring 33 squeeze each other, pushing the limit sleeve 25 to move to both sides. The telescopic plate 24 will also telescope to both sides with the movement of the limit sleeve 25. As the copper sleeve descends, the limit ring continues to contact the fixed ring 33 until it reaches the locked position. The positioning spring 26 restores the limit sleeve 25 to its original position, the copper sleeve is fixed and the positioning accuracy is ensured. At this time, the deadweight of the copper sleeve will continue to act, and the limit ring will further mate with the sliding ring 35. The position of the copper sleeve is fixed. After the drilling process is completed, the operator can press the copper sleeve downward to push the limit ring to the bottom of the sliding ring 35 to release the lock, and separate the limit ring from the fixing ring 33 by pulling upward, so that the copper sleeve can be removed smoothly to prepare for the next processing. The design of the limit sleeve 25 and the telescopic plate 24 makes the positioning tool 20 adaptive. Under copper sleeves of different specifications, the positioning component can be automatically adjusted through the cooperation of the limit ring and the sliding ring 35 to adapt to the positioning of copper sleeves of different sizes, thereby improving the versatility and adaptability of the equipment.

[0039] A moving rod 27 is slidably installed in the middle of the fixed block 23. The moving rod 27 penetrates the fixed block 23. A locking block 28 is fixedly connected to one end of the moving rod 27 close to the limiting sleeve 25. A return spring is sleeved on the outer surface of the moving rod 27 between the locking block 28 and the fixed block 23. A cam 29 is rotatably installed on one end of the moving rod 27 away from the limiting sleeve 25. A connecting plate 30 is fixedly connected to one side of the cam 29. A first trigger rod 31 and a second trigger rod 32 are fixedly connected to the middle of the connecting plates 30 respectively. The first trigger rod 31 and the second trigger rod 32 are both arranged in an arc shape, and the second trigger rod 32 is embedded and installed inside the first trigger rod 31.

[0040] First, after positioning the copper sleeve body, the operator can drive the connecting plate 30 to move by rotating the first trigger rod 31 and the second trigger rod 32, thereby driving the cam 29 to rotate. As the cam 29 rotates, the moving rod 27 moves accordingly, thereby driving the locking block 28 to fix and lock the various surfaces of the copper sleeve. During the locking process, the reset spring will be compressed and provide a reaction force to ensure that the system can be quickly reset after the locking action is completed, and prepare for the next operation. In this way, the six-sided fixation of the stainless steel joint screw head can be accurately controlled to ensure the stability and accuracy during the processing. By rotating the first trigger rod 31 and the second trigger rod 32, the connecting plate 30 and the cam 29 can be driven to move, and the locking of the various surfaces of the stainless steel joint screw head can be achieved. This process ensures that the copper sleeve body is accurately fixed at multiple points during the processing, avoiding any possible offset or looseness, and improving the stability and accuracy of the processing process. By locking the various surfaces of the copper sleeve body evenly by the locking block 28, the stability of the copper sleeve body during the processing can be guaranteed to the greatest extent, and the processing error caused by insufficient locking of individual surfaces can be avoided.
