Description

Technical Field

[0001] This application relates to the field of workpiece clamping, and in particular to a clamping mechanism. Background Technology

[0002] In the manufacturing process of rotor shafts, rotor weight removal is a key technological step to ensure balanced operation of the rotor. This step removes excess weight from the rotor, enabling it to reach a stable equilibrium state. Currently, there are various methods for rotor weight removal, among which drilling is one of the more common methods. When performing drilling weight removal, the rotor must be clamped with a fixture to ensure the accuracy and safety of the weight removal process.

[0003] However, most existing de-lamination processes use vises for clamping. Due to limitations in its structure and working principle, vises are difficult to integrate effectively with automated machine tool systems. They rely entirely on manual operation throughout the entire processing, which not only significantly reduces production efficiency but also easily affects processing accuracy due to human error, increasing labor costs and product defect rates. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides a clamping mechanism that can automatically clamp the workpiece during drilling and weight removal.

[0005] The clamping mechanism provided in this application adopts the following technical solution:

[0006] A clamping mechanism includes a frame, on which a support component and a clamping component are provided. The support component includes a first support seat, and the clamping component includes a clamping block movably disposed along a direction close to or away from the first support seat, and a first drive module for driving the clamping block to move. The clamping block has a clamping position that is positively aligned with the first support seat during its movement stroke.

[0007] By adopting the above technical solution, the clamping block can clamp the workpiece onto the first bearing seat during its movement stroke, thereby realizing automatic clamping of the workpiece. This not only improves the clamping effect of the workpiece, but also enables the clamping block to cooperate with the machine tool and realize the automated production of the workpiece, effectively improving the production efficiency of the workpiece.

[0008] In one specific implementation scheme, the first bearing seat is provided with a first bearing groove, and the clamping block is provided with a clamping groove. When the clamping block is in the clamping position, the center line of the first bearing groove and the center line of the clamping groove coincide with each other.

[0009] By adopting the above technical solution, when the clamping block is in the clamping position, the workpiece can be accommodated between the clamping block and the first bearing seat, and the clamping groove and the first bearing groove can be properly aligned and effectively clamp the workpiece, thereby further improving the clamping effect of the workpiece.

[0010] In one specific implementation, the clamping assembly further includes a clamping seat and a clamping rod with one end hinged to the clamping seat. The rotation axis of the clamping rod is parallel to the center line of the clamping groove. The output end of the first drive module is connected to the clamping rod in a driving connection. The clamping block is disposed at the end of the clamping rod away from the clamping seat.

[0011] By adopting the above technical solution, the clamping rod can drive the clamping block to accurately align with the first bearing seat, preventing the clamping block and the first bearing seat from being misaligned and affecting the clamping effect on the workpiece.

[0012] In one specific implementation, the clamping assembly further includes a transmission module disposed between the output end of the first drive module and the clamping rod. The transmission module includes a first transmission frame and a second transmission frame. The first transmission frame has three hinged ends, which are respectively hinged to the output end of the first drive module, the clamping seat, and the second transmission frame. The second transmission frame has two hinged ends, which are respectively hinged to the first transmission frame and the clamping rod.

[0013] By adopting the above technical solution, the clamping rod can rotate quickly and accurately under the transmission cooperation of the first transmission frame and the second transmission frame, which can not only improve the clamping strength of the clamping block, but also reduce the output burden of the first drive module.

[0014] In one specific implementation, the first transmission frame includes two opposing first frames, which are respectively hinged to both sides of the clamping seat. The second transmission frame includes two opposing second frames, which are located between the two first frames and are respectively hinged to both sides of the clamping rod's rotation direction.

[0015] By adopting the above technical solution, the transmission stability of the first transmission frame and the second transmission frame is effectively improved.

[0016] In one specific implementation, the clamping assembly further includes a limiting rod disposed on the clamping rod, the limiting rod being located on the side of the first transmission frame near the clamping block.

[0017] By adopting the above technical solution, the limiting rod can limit the rotation of the first transmission frame, preventing the first transmission frame from rotating excessively and causing damage to the workpiece.

[0018] In one specific implementation, the clamping seat is disposed on the side of the first support seat, and the arrangement direction of the clamping seat and the first support seat is perpendicular to the length direction of the first support groove.

[0019] In one specific implementation, the clamping seat is provided with a mounting bracket, and the mounting end of the first drive module is hinged to the mounting bracket.

[0020] By adopting the above technical solution, the installation strength of the first drive module is effectively improved, thereby enhancing the driving effect of the first drive module.

[0021] In one specific implementation, the support assembly further includes at least two second support seats located on both sides of the first support seat. Each of the second support seats has a second support groove, and the center line of the second support groove coincides with the center line of the first support groove.

[0022] By adopting the above technical solution, the second bearing seat can cooperate with the first bearing seat to bear the workpiece, thereby further improving the clamping effect of the workpiece.

[0023] In one specific implementation, the clamping mechanism further includes a liftable fixed plate mounted on the frame, a second drive module for driving the fixed plate to move up and down, and the bearing component and the clamping component are respectively mounted on the fixed plate.

[0024] By adopting the above technical solution, the fixing plate can drive the bearing component and the clamping component to support the workpiece during its lifting and lowering process, which effectively improves the production efficiency of the workpiece.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] The clamping block can clamp the workpiece onto the first bearing seat during its movement stroke, thereby achieving automatic clamping of the workpiece. This not only improves the clamping effect of the workpiece, but also allows the clamping block to work with the machine tool to achieve automated production of the workpiece, effectively improving the production efficiency of the workpiece.

[0033] 100. Shaft-type workpieces. Detailed Implementation

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] See Figure 1 As shown, a clamping mechanism is illustrated for clamping shaft-type workpieces such as rotor shafts. It includes a frame 1, on which a bearing assembly 2 and a clamping assembly 3 are provided. The bearing assembly 2 includes a first bearing seat 21. The clamping assembly 3 includes a clamping block 31 that is movably disposed along a direction close to or away from the first bearing seat 21, and a first drive module 32 for driving the clamping block 31 to move. The clamping block 31 has a clamping position that is positively aligned with the first bearing seat 21 during its movement stroke.

[0036] In this way, when processing the shaft workpiece 100, the shaft workpiece 100 is placed on the first bearing seat 21, and then the clamping block 31 can clamp the shaft workpiece 100 on the first bearing seat 21 during its movement stroke, thereby realizing the automatic clamping of the shaft workpiece 100. This not only improves the clamping effect of the shaft workpiece 100, but also allows the clamping block 31 to cooperate with the machine tool to realize the automated production of the shaft workpiece 100 without manual operation, effectively improving the production efficiency of the shaft workpiece 100.

[0037] In this embodiment, the first bearing seat 21 is arranged horizontally and has a first bearing groove 22. The first bearing groove 22 extends along the length of the frame 1. The clamping block 31 has a clamping groove 33. When the clamping block 31 is in the clamping position, the center line of the first bearing groove 22 coincides with the center line of the clamping groove 33. At this time, the shaft workpiece 100 can be accommodated between the clamping block 31 and the first bearing seat 21. The clamping groove 33 and the first bearing groove 22 can be properly aligned and effectively clamp the shaft workpiece 100, thereby further improving the clamping effect of the shaft workpiece 100.

[0038] In this embodiment, the clamping assembly 3 further includes a clamping seat 34 disposed on the side of the first support seat 21 and a clamping rod 35 hinged to the clamping seat 34 at one end. The arrangement direction of the clamping seat 34 and the first support seat 21 is perpendicular to the length direction of the first support groove 22. The rotation axis of the clamping rod 35 extends along the length direction of the frame 1 and is parallel to the center line of the clamping groove 33. The output end of the first drive module 32 is connected to the clamping rod 35. The clamping block 31 is disposed at the end of the clamping rod 35 away from the clamping seat 34. The clamping rod 35 can drive the clamping block 31 to accurately align with the first support seat 21, preventing the clamping block 31 and the first support seat 21 from being misaligned and affecting the clamping effect of both on the shaft workpiece 100.

[0039] Furthermore, the clamping assembly 3 also includes a transmission module disposed between the output end of the first drive module 32 and the clamping rod 35. The transmission module includes a first transmission frame 36 and a second transmission frame 37. The first transmission frame 36 is T-shaped and has three hinged ends, which are respectively hinged to the output end of the first drive module 32, the clamping seat 34, and the second transmission frame 37. The second transmission frame 37 has two hinged ends, which are respectively hinged to the first transmission frame 36 and the clamping rod 35. The rotation axes between the first transmission frame 36 and the output end of the first drive module 32, between the first transmission frame 36 and the clamping seat 34, between the first transmission frame 36 and the second transmission frame 37, and between the second transmission frame 37 and the clamping rod 35 extend along the length direction of the frame 1.

[0040] When the first drive module 32 drives the clamping rod 35 to move, the first transmission frame 36 and the second transmission frame 37 can be combined to form a linkage mechanism. The clamping rod 35 can rotate quickly and accurately under the transmission cooperation of the first transmission frame 36 and the second transmission frame 37, which can not only improve the clamping strength of the clamping block 31, but also reduce the output burden of the first drive module 32.

[0041] In this embodiment, the first transmission frame 36 includes two opposing first frame bodies 361, which are respectively hinged to both sides of the clamping seat 34. The second transmission frame 37 includes two opposing second frame bodies 371, which are located between the two first frame bodies 361 and are respectively hinged to both sides of the clamping rod 35 in the rotation direction. The arrangement direction of the two first frame bodies 361 and the arrangement direction of the two second frame bodies 371 are the same as the length direction of the frame 1, which can effectively improve the transmission stability of the first transmission frame 36 and the second transmission frame 37.

[0042] In this embodiment, the clamping assembly 3 further includes a limiting rod 38 disposed on the clamping rod 35, the limiting rod 38 being located on the side of the first transmission frame 36 near the clamping block 31. There are two limiting rods 38, located on opposite sides of the clamping rod 35 in the direction of rotation. Both limiting rods are used to limit the movement of the two first frames 361, preventing excessive rotation of the first transmission frame 36 and thus preventing damage to the shaft-like workpiece 100.

[0043] In this embodiment, a mounting bracket 39 is provided at the bottom of the clamping seat 34, and the mounting end of the first drive module 32 is hinged to the mounting bracket 39. The first drive module 32 is a cylinder, with its output end being the piston rod and its mounting end being the cylinder body.

[0044] In this embodiment, the support assembly 2 further includes two second support seats 23, which are located on both sides of the first support seat 21 and arranged along the length of the frame 1. Each second support seat 23 has a second support groove 24, the center line of which coincides with the center line of the first support groove 22. The second support seats 23 can cooperate with the first support seat 21 to support the shaft workpiece 100. The middle part of the shaft workpiece 100 is supported in the first support groove 22, and the two ends are supported in the two second support grooves 24, which can further improve the clamping effect of the shaft workpiece 100.

[0045] In this embodiment, the clamping mechanism further includes a liftable fixed plate 4 mounted on the frame 1, a second drive module 5 for driving the fixed plate 4 to rise and fall, and a bearing assembly 2 and a clamping assembly 3 respectively mounted on the fixed plate 4. The fixed plate 4 is horizontally positioned, and the second drive module 5 is a cylinder. During its lifting and lowering process, the fixed plate 4 can drive the bearing assembly 2 and the clamping assembly 3 to rise and support the shaft-type workpiece 100, effectively improving the production efficiency of the shaft-type workpiece 100.

[0046] In this embodiment, a fiber optic sensor 6 is also provided on the frame 1. After the shaft workpiece 100 is placed on the support assembly 2, the fiber optic sensor 6 passes through the fixing plate 4 and abuts against the side of the shaft workpiece 100 to detect the placement of the shaft workpiece 100. The fixing plate 4 is also provided with a clearance opening 7 for the fiber optic sensor 6 to pass through.

[0047] The implementation principle of a clamping mechanism according to an embodiment of this application is as follows:

[0048] The second drive module 5 drives the fixed plate 4 to rise, placing the shaft workpiece 100 on the first bearing seat 21, and making the two ends of the shaft workpiece 100 bear on the two second bearing seats 23. Then, the first drive module 32 drives the clamping rod 35 to rotate through the cooperation of the first transmission frame 36 and the second transmission frame 37. The clamping rod 35 drives the clamping block 31 to move and clamp onto the shaft workpiece 100, thereby completing the clamping of the shaft workpiece 100.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
