Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment technology, and in particular to a multi-station ultra-precision grinding mechanism for machining ultra-long eccentric groove inner rings. Background Technology

[0002] In the field of precision manufacturing, especially for the machining of ultra-long off-center inner rings, there are extremely high requirements for the precision and efficiency of equipment. Traditional machining methods mostly rely on manual or semi-automatic equipment with a single station, which not only limits the machining efficiency but also makes it difficult to ensure product consistency and high precision. With the continuous advancement of automation technology, multi-station ultra-precision machining mechanisms have gradually entered the market, aiming to improve machining efficiency and product quality through automation.

[0003] However, most existing multi-station ultra-precision machining mechanisms have a key problem: they can only adjust each station individually and cannot achieve synchronous control of multiple stations. This individual adjustment method not only increases the complexity of operation and reduces the overall processing efficiency, but also makes it difficult to ensure the consistency and coordination of processing between stations. In addition, individual adjustment may lead to the accumulation of errors during the processing, affecting the accuracy and quality of the final product.

[0004] Based on this, the applicant proposed a multi-station ultra-precision machining mechanism for processing ultra-long eccentric groove inner rings to solve the above technical problems. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a multi-station ultra-precision machining mechanism for processing ultra-long eccentric groove inner rings, thereby solving the aforementioned technical problems.

[0006] This utility model is solved by the following technical solution:

A drive motor is connected to the end of the output shaft. Several cams are mounted on the output shaft. Several reset devices corresponding to the cams are slidably mounted inside the base. The lower end of the reset device cooperates with the cam, and the upper end of the reset device cooperates with the connector of each station. When the output shaft rotates, the several cams simultaneously control the corresponding reset devices to slide.

[0010] Preferably, the lower end of the resetter is rotatably provided with a matching wheel abutting against the cam.

[0011] Preferably, the upper end of the resetter is provided with a follower wheel abutting against the connector.

[0012] Preferably, a plurality of fixed sleeves are fixedly arranged on the base, and the resetters are slidingly connected in the fixed sleeves.

[0013] Preferably, the super lapping machine further comprises a connecting shaft, an abutting plate is fixedly arranged on the connecting shaft, the connector is rotatably arranged on the connecting shaft, a pneumatic cylinder is further fixedly installed on the connector, a telescopic rod is arranged on the pneumatic cylinder, the end of the telescopic rod abuts against the abutting plate, and a swing rod is fixedly arranged on the connector, and an oilstone is fixedly installed at the end of the swing rod.

[0014] Preferably, when the super lapping machine works, the pneumatic cylinder works to make the telescopic rod elongate, the end of the telescopic rod abuts against the abutting plate and slides upward, so as to make the connector rotate downward, at the same time, the driving motor controls the cam to rotate, under the joint influence of the connector and the cam, the resetters slide downward and their two ends abut against the connector and the cam respectively, and after the oilstone contacts the workpiece, the pneumatic cylinder and the driving motor stop running.

[0015] Preferably, after the super lapping machine completes machining, the driving motor controls the cam to rotate, under the influence of the cam, the resetters slide upward, at the same time, the pneumatic cylinder works to make the telescopic rod shorten, under the action of the upward sliding of the resetters, the connector rotates upward, the end of the telescopic rod abuts against the abutting plate and slides downward, and after the connector resets, the pneumatic cylinder and the driving motor stop running.

[0016] The beneficial effects of the utility model lie in:

[0017] 1. Significantly improve the machining efficiency: through the innovative cam-resetter-connector transmission system, the synchronous control of multiple stations is realized, the time waste caused by the separate adjustment of each station in the traditional equipment is avoided, and the overall machining efficiency is greatly improved;

[0029] The technical solutions of various embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

A drive motor 1 is connected to the end of the output shaft 2. Several cams 3 are arranged on the output shaft 2. Several resetters 6, corresponding one-to-one with the cams 3, are slidably arranged inside the base 4. The lower end of the resetter 6 cooperates with the cam 3, and the upper end of the resetter 6 cooperates with the connector 9 of each station. When the output shaft 2 rotates, the several cams 3 control the corresponding resetters 6 to slide up or down simultaneously.

[0031] Through an innovative cam-resetter-connector transmission system, synchronous control of multiple workstations is achieved, avoiding the time waste caused by individually adjusting each workstation in traditional equipment, thereby significantly improving overall processing efficiency. The synchronous control mechanism ensures that the actions of all workstations are coordinated and consistent during the processing, effectively reducing error accumulation, improving the processing accuracy of products and batch consistency, and meeting the needs of high-precision manufacturing.

[0032] A plurality of fixed sleeves 5 are fixedly installed on the base 4. The resetter 6 is slidably connected inside the fixed sleeves 5. A mating wheel 7 is rotatably installed at the lower end of the resetter 6. The mating wheel 7 abuts against the cam 3. A follower wheel 8 is installed at the upper end of the resetter 6.

[0033] The ultra-precision grinding machine also includes a connecting shaft 14, on which an abutment plate 13 is fixedly mounted. The connector 9 is rotatably mounted on the connecting shaft 14.

[0034] When the ultra-precision grinding machine is working, the cylinder 12 extends the telescopic rod, and the end of the telescopic rod abuts against the abutment plate 13 and slides upward, thereby causing the connector 9 to rotate downward. At the same time, the drive motor 1 controls the cam 3 to rotate. Affected by the connector 9 and the cam 3, the resetter 6 slides downward and its two ends abut against the connector 9 and the cam 3 respectively, until the oilstone 11 contacts the workpiece, at which point the cylinder 12 and the drive motor 1 stop running.

[0035] After the ultra-precision grinding machine completes the processing, the drive motor 1 controls the cam 3 to rotate. Affected by the cam 3, the reset device 6 slides upward. At the same time, the cylinder 12 works to shorten the telescopic rod. Affected by the upward sliding of the reset device 6, the connector 9 rotates upward.

A drive motor 1 is connected to the end of the output shaft 2. Several cams 3 are mounted on the output shaft 2. Several resetters 6, each corresponding to a cam 3, are slidably mounted inside the base 4. The lower end of the resetter 6 engages with the cam 3, and the upper end of the resetter 6 engages with the connector 9 at each station. The resetters 6 are divided into several groups. The cam 3 corresponding to each group of resetters 6 has a different deflection angle on the output shaft 2. The cams 3 corresponding to several resetters 6 in the same group have the same deflection angle on the output shaft 2. When the output shaft 2 rotates, the several resetters 6 in the same group slide up or down simultaneously, and the groups of resetters 6 slide up or down alternately.

[0037] Through an innovative cam-resetter-connector transmission system, synchronous control of multiple workstations is achieved, avoiding the time waste caused by adjusting each workstation individually in traditional equipment, thereby significantly improving overall processing efficiency. By changing the deflection angle of the cam on the output shaft or adjusting the grouping strategy of the resetter, it can easily adapt to diverse processing needs, enhancing the equipment's versatility and market competitiveness.

A rocker arm 10 is fixedly mounted on the connector 9. An oilstone 11 is fixedly mounted at the end of the rocker arm 10.

[0040] When the ultra-precision grinding machine is working, the cylinder 12 extends the telescopic rod, and the end of the telescopic rod abuts against the abutment plate 13 and slides upward, thereby causing the connector 9 to rotate downward. At the same time, the drive motor 1 controls the cam 3 to rotate. Affected by the connector 9 and the cam 3, the resetter 6 slides downward and its two ends abut against the connector 9 and the cam 3 respectively, until the oilstone 11 contacts the workpiece, at which point the cylinder 12 and the drive motor 1 stop running.

[0041] After the ultra-precision grinding machine completes the processing, the drive motor 1 controls the cam 3 to rotate. Affected by the cam 3, the reset device 6 slides upward. At the same time, the cylinder 12 works to shorten the telescopic rod. Affected by the upward sliding of the reset device 6, the connector 9 rotates upward. The end of the telescopic rod abuts against the abutment plate 13 and slides downward until the connector 9 is reset. Then, the cylinder 12 and the drive motor 1 stop running. Example 3:

[0042] like Figures 5 to 6 As shown, this utility model discloses a multi-station ultra-precision grinding mechanism for processing ultra-long eccentric groove inner rings. The output shaft 2 can be extended and connected to another ultra-precision grinding machine. Several cams 3 are also set there, so that more stations can be controlled simultaneously. Based on this design, the output shaft 2 and cams 3 can be modularly designed, and more ultra-precision grinding machines can be connected as needed to achieve consistency in processing the same batch of workpieces, improve processing efficiency, and can be used as an assembly line. The deflection angle of different cams 3 can be adjusted to control the processing state of different stations, thereby meeting the needs of assembly line operation.
