[0001] This utility model relates to the technical field of indexing chucks, and more particularly to an indexing chuck with adjustable stroke. Background Technology

[0002] Indexing chucks are playing an increasingly important role in the modern machining industry. They enable the machining of multiple surfaces of a workpiece in a single clamping operation, greatly reducing the time spent assembling and disassembling workpieces, thereby improving production efficiency and reducing costs.

[0003] When using an indexing chuck to process a workpiece, the use of hydraulic transmission to control the rotation of the fixture results in certain limitations on the angle of rotation, which is relatively fixed. This prevents the indexing chuck from flexibly adjusting the rotation stroke during workpiece processing, thus limiting its applicability. Therefore, different specifications of indexing chucks are usually used to meet processing requirements, but this not only increases processing costs but also reduces processing efficiency.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] An adjustable stroke indexing chuck according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown, an adjustable stroke indexing chuck according to an embodiment of the present invention includes: an indexing chuck 1 and an adjustment mechanism 2.

[0026] The adjustment mechanism 2 includes a fixed tooth 22, a first bevel tooth 23, a second bevel tooth 24, a connecting rod 25, and a servo motor 26.

[0027] The fixed tooth 22 is located inside the indexing chuck 1, the first bevel tooth 23 is located on the outer wall of the fixed tooth 22, the second bevel tooth 24 is meshed with the first bevel tooth 23, one end of the connecting rod 25 is connected to the second bevel tooth 24, and the shaft of the servo motor 26 is connected to the other end of the connecting rod 25.

[0028] Specifically, when it is necessary to adjust the rotational stroke of the upper rotating claw 13, the rotation angle of the upper rotating claw 13 can be achieved by controlling the direction and speed of the servo motor 26.

[0029] When the upper rotating claw 13 needs to be driven to rotate, the servo motor 26 is started. The shaft of the servo motor 26 drives the connecting rod 25 to rotate. The connecting rod 25 drives the second bevel tooth 24 to rotate. The second bevel tooth 24 drives the first bevel tooth 23 that meshes with it to rotate. The first bevel tooth 23 drives the fixed tooth 22 to rotate. Thus, the rotation stroke of the upper rotating claw 13 is adjusted through a series of transmission structures.

[0030] In one embodiment of this application, such as Figure 4 As shown, the indexing chuck 1 is equipped with a clamping component 3.

[0031] The clamping assembly 3 includes a push rod 33, a first limiting ring 34, and a second limiting ring 35.

[0032] The indexing chuck 1 has a first oil inlet hole 31 on its outer wall, a second oil inlet hole 32 on its outer wall, a push rod 33 inside the indexing chuck 1, a first limiting ring 34 on the outer wall of the push rod 33, and a second limiting ring 35 on the outer wall of the push rod 33.

[0033] Specifically, when the workpiece needs to be clamped, hydraulic oil first enters below the connecting rod 25 through the second oil inlet 32, pushing the push rod 33 to move upward. During the movement, the push rod 33 drives the first limiting ring 34 and the second limiting ring 35 to move synchronously. The second limiting ring 35 is designed to prevent hydraulic oil from entering between the first limiting ring 34 and the second limiting ring 35.

[0034] When it is necessary to loosen the workpiece, hydraulic oil enters between the first limiting ring 34 and the second limiting ring 35 through the first oil inlet 31. The hydraulic oil pushes the second limiting ring 35 to move downward, thereby driving the push rod 33 and the second limiting ring 35 to move downward synchronously, thus loosening the workpiece.

[0035] In one embodiment of this application, such as Figure 5 As shown, a sealing assembly 4 is provided on the push rod 33.

[0036] The sealing assembly 4 includes a first sealing ring 42 and a second sealing ring 44.

[0037] The second limiting ring 35 has a first mounting groove 41, and the first sealing ring 42 is disposed on the inner wall of the first mounting groove 41. The first limiting ring 34 has a second mounting groove 43, and the second sealing ring 44 is disposed on the inner wall of the second mounting groove 43.

[0038] Specifically, the first sealing ring 42 and the second sealing ring 44 effectively prevent hydraulic oil leakage and ensure the normal operation of the clamping assembly 3.

[0039] The first sealing ring 42 is disposed in the first mounting groove 41 on the second limiting ring 35. When hydraulic oil enters through the second oil inlet 32, the first sealing ring 42 can fit tightly in the gap between the second limiting ring 35 and the indexing chuck 1 to prevent hydraulic oil leakage.

[0040] Similarly, the second sealing ring 44 is disposed in the second mounting groove 43 on the first limiting ring 34. When hydraulic oil enters through the first oil inlet 31, the second sealing ring 44 can fit tightly in the gap between the first limiting ring 34 and the push rod 33, further preventing hydraulic oil leakage.

[0041] In one embodiment of this application, such as Figure 1 As shown, the indexing chuck 1 includes a disc body 11, a lower clamping jaw 12, and an upper rotating jaw 13.

[0042] The lower gripper 12 is located inside the disc body 11, and the upper rotating gripper 13 is located inside the disc body 11.

[0043] Specifically, the lower clamping jaw 12 is used to fix the workpiece, while the upper rotating jaw 13 is rotated by the adjustment mechanism 2 to adjust the position or angle of the workpiece. Both the lower clamping jaw 12 and the upper rotating jaw 13 are made of high hardness and wear resistance, which can withstand large clamping force and rotation torque, while ensuring clamping accuracy and rotation stability.

[0044] In one embodiment of this application, such as Figure 2 and Figure 4 As shown, a second screw 6 is provided on the lower clamping claw 12, and the second screw 6 passes through the lower clamping claw 12 and is connected to the push rod 33.

[0045] Understandably, the second screw 6 allows for easy connection between the lower clamping claw 12 and the push rod 33, and also facilitates subsequent disassembly and maintenance.

[0046] In one embodiment of this application, such as Figure 2 and Figure 3 As shown, a first screw 5 is provided on the first bevel tooth 23, and the first screw 5 passes through the first bevel tooth 23 and is connected to the lower clamping claw 12.

[0047] Understandably, by setting the first screw 5, the first bevel tooth 23 can be firmly connected to the lower clamping jaw 12, ensuring the stability and reliability of the transmission, and also facilitating subsequent disassembly and maintenance.

[0048] In one embodiment of this application, such as Figure 3 As shown, a ball bearing 21 is provided on the outer wall of the fixed tooth 22.

[0049] Understandably, the ball bearing 21 reduces the frictional resistance of the fixed tooth 22 during rotation, improves the smoothness and accuracy of rotation, and also extends the service life of the fixed tooth 22.

[0050] Working principle: When it is necessary to adjust the rotational stroke of the upper rotating claw 13, the rotation angle of the upper rotating claw 13 can be achieved by controlling the direction and speed of the servo motor 26. When it is necessary to drive the upper rotating claw 13 to rotate, the servo motor 26 is started. The shaft of the servo motor 26 drives the connecting rod 25 to rotate. The connecting rod 25 drives the second bevel tooth 24 to rotate. The second bevel tooth 24 drives the first bevel tooth 23 that meshes with it to rotate. The first bevel tooth 23 drives the fixed tooth 22 to rotate. Thus, the rotational stroke of the upper rotating claw 13 is adjusted through a series of transmission structures. Simultaneously, through the clamping assembly 3, when the workpiece needs to be clamped, hydraulic oil first enters below the connecting rod 25 through the second oil inlet 32, pushing the push rod 33 to move upward. During the movement, the push rod 33 drives the first limiting ring 34 and the second limiting ring 35 to move synchronously. The setting of the second limiting ring 35 can prevent hydraulic oil from entering between the first limiting ring 34 and the second limiting ring 35. When the workpiece needs to be released, hydraulic oil enters between the first limiting ring 34 and the second limiting ring 35 through the first oil inlet 31. The hydraulic oil pushes the second limiting ring 35 to move downward, thereby driving the push rod 33 and the second limiting ring 35 to move downward synchronously, thus releasing the workpiece. Furthermore, the sealing assembly 4, the first sealing ring 42, and the second sealing ring 44 effectively prevent hydraulic oil leakage and ensure the normal operation of the clamping assembly 3. The first sealing ring 42 is located in the first mounting groove 41 on the second limiting ring 35. When hydraulic oil enters through the second oil inlet 32, the first sealing ring 42 can fit tightly in the gap between the second limiting ring 35 and the indexing chuck 1 to prevent hydraulic oil leakage. Similarly, the second sealing ring 44 is located in the second mounting groove 43 on the first limiting ring 34. When hydraulic oil enters through the first oil inlet 31, the second sealing ring 44 can fit tightly in the gap between the first limiting ring 34 and the push rod 33 to further prevent hydraulic oil leakage.

[0051] In summary, the adjustable stroke indexing chuck of this utility model, through the setting of the adjustment mechanism 2, achieves flexible adjustment of the rotation stroke of the upper rotating jaw 13 by precise control of the servo motor 26 during adjustment, meeting the needs of different workpiece processing. At the same time, the setting of the clamping component 3 and the sealing component 4 not only ensures the stability and accuracy of workpiece clamping, but also effectively prevents hydraulic oil leakage, thereby improving the reliability and service life of the equipment.
