[0002] The spinning assembly involves a large number of disc-shaped workpieces, most of which are processed with eccentric hole structures. According to structural requirements, some eccentric hole end faces need to be processed with annular groove structures on the outside of the hole. For the processing of the annular groove, there are high dimensional accuracy requirements for the concentricity of the annular groove relative to the corresponding eccentric hole. When traditional positioning fixtures are used to position and clamp eccentric holes of different degrees, different clamping and debugging are required to ensure the stability of the workpiece and ensure accuracy. This results in the need for multiple debugging and clamping if multiple eccentric holes with different degrees of eccentricity need to be processed with annular grooves on the workpiece, affecting the processing efficiency.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a schematic diagram of the overall structure of an embodiment of the present utility model. DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] As attached Figure 1The eccentric hole ring groove processing device described above includes a rotating fixture 1 and a movable fixture 2. The rotating fixture 1 clamps a multi-eccentric hole workpiece 3 at its center position. The rotating fixture 1 rotates so that one eccentric hole of the workpiece 3 corresponds to the positioning column 21 of the movable fixture 2; the positioning column 21 is raised and lowered perpendicular to the positioning table of the rotating fixture 1, and the positioning column 21 is inserted and matched with the eccentric hole of the workpiece 3; the positioning column 21 is set to move radially along the rotating fixture 1, and when the positioning column 21 moves to the center position of the rotating fixture 1, the eccentric hole of the workpiece 3 is aligned up and down with the tool mechanism; the tool mechanism includes a tool module 4, and the tool module 4 is set to rotate around the axis of the rotating shaft of the rotating fixture 1, and the tool module 4 is set to move radially along the rotating fixture 1.

[0017] In the initial state, the workpiece to be processed is first positioned and installed relative to the rotating fixture, and the rotating fixture drives the workpiece to rotate so that the radial direction of any eccentric hole on it coincides with the moving direction of the movable fixture. The movable fixture is then used to adjust its positioning column along the radial direction. When the positioning column is aligned with the eccentric hole on the workpiece, the positioning column extends and cooperates with the eccentric hole insertion to determine the position of the workpiece relative to a certain fixture. Then, through further clamping and fixing, the movable fixture drives the workpiece to move the eccentric distance until it is aligned with the tool mechanism. The tool mechanism can then adjust the radial movement distance of the tool module according to the inner and outer ring radii of the required processing ring groove, and cooperate with the uniform speed of the tool module to complete the processing of the ring groove. After processing is completed, the movable fixture drives the workpiece to a concentric position with the turntable and retracts the positioning column. The turntable rotates again and the positioning column moves to make the next eccentric hole correspond to the position of the positioning column. The above alignment and processing steps are repeated, thereby continuously completing the processing of multiple eccentric hole ring grooves without the need for multiple clamping, effectively improving processing efficiency.

[0018] The movable fixture 2 comprises a movable platform that moves radially along the rotating fixture 1. A positioning post 21 is fixedly positioned on the movable platform and raised and lowered. Clamping blocks 22 are positioned on either side of the positioning post 21 in the direction of the movable platform's movement. The two clamping blocks 22 slide relative to each other to clamp the workpiece 3. The movable platform is positioned on the underside of the turntable. The two clamping blocks apply a radial clamping force to the workpiece. The clamping direction is collinear with the positioning post and coincides with the direction of movement. This prevents the workpiece from rotating relative to the positioning post, ensuring that the workpiece remains firmly positioned relative to the movable platform during movement and that the workpiece maintains a concentric position with the turntable after resetting.

[0019] Limit blocks 5 are symmetrically arranged on both sides of the rotating fixture 1. The two limit blocks 5 move closer or further away from each other radially along the rotating fixture 1. The limit blocks 5 are provided with limit surfaces that match the contour surface of the workpiece 3. The two limit blocks 5 are located on both sides of the movable fixture 2. The limit surfaces are arc surfaces that fit the outer cylindrical surface of the workpiece. When loading and installing the workpiece, the limit blocks and positioning columns on both sides are moved to the specified positions. The positioning columns cooperate with the eccentric holes, and the limit blocks on both sides cooperate with the outer cylindrical surface of the workpiece to achieve positioning and installation of the workpiece, ensuring the initial loading position accuracy. After the workpiece is clamped by the movable fixture or the rotating fixture, the limit blocks are moved away from the workpiece to avoid motion interference.

[0020] The center of the turntable of the rotating fixture 1 is provided with an escape space for the positioning column 21 to extend and move. A plurality of flip clamps 11 are provided on the circumference of the turntable of the rotating fixture 1. When the flip clamps 11 clamp the workpiece, they fit with the outer side surface and upper end surface of the workpiece. Preferably, the turntable is provided with an annular table surface, and a plurality of flip clamps are hingedly provided on the outside of the annular turntable. The outer side surface of the turntable can be connected to the bracket structure through a bearing. The bracket structure is used to support and fix the turntable. The turntable can be provided with a gear surface through the outer cylindrical surface for cooperating with the driving gear to realize the rotation of the turntable. The cavity in the middle of the turntable can be used as the escape space, which can meet the corresponding insertion and cooperation of the positioning column and the eccentric hole of any radius within a certain range.

[0021] The contact surface between the flip clamp 11 and the outer side of the workpiece is provided with a clamping in place sensing module, and the induction signal output end of the clamping in place sensing module is electrically connected to the clamping control signal receiving end of the driving device of the clamp block 22. The clamping surface between the clamp block 22 and the workpiece 3 is provided with a clamping in place sensing module, and the induction signal output end of the clamping in place sensing module is electrically connected to the clamping control signal receiving end of the flip clamp. The positioning table of the rotating clamp 1 is provided with a contact sensing module, and the extension limit position of the positioning column 21 is provided with an in-place sensor. The signal output ends of the contact sensing module and the in-place sensor are electrically connected to the clamping control signal receiving end of the driving device of the clamp block 22.

[0022] Based on the layout and connection relationship of the above-mentioned control module and sensing module, the mobile fixture can be triggered to clamp the workpiece only when the workpiece is completely in contact with the turntable table and the positioning column rises to the upper limit position. Before completing all processing tasks, the mobile fixture and the rotating fixture alternately clamp multiple workpieces, and drive the workpieces to rotate and move respectively in their respective clamping states, thereby achieving reliable movement coordination and avoiding interference in mutual movement.

[0023] Embodiment: First, according to the preset processing sequence, the position coordinates of the limit block and the positioning column in the initial state are determined with the position of the first processed eccentric hole, and then the positions of the three are installed to position and install the workpiece. At this time, the positioning column is in the upper limit position. Only when the workpiece is completely concentric with the turntable can the workpiece be smoothly fitted with the limit block and lowered to fit with the turntable table surface, thereby triggering the clamping action of the two adding blocks of the mobile fixture. After clamping, the limit block is driven away from the workpiece, and the mobile table is moved by the preset distance to correspond to the tool mechanism. The tool mechanism completes the processing of the eccentric hole ring groove according to the preset processing parameters; then the mobile table is reset to the initial position, triggering the flip clamp of the rotating fixture to perform the clamping action. When multiple flip clamps are clamped and fit against the outer cylindrical surface of the workpiece, it is determined that the workpiece is clamped and fixed relative to the rotating clamp, thereby triggering the loosening action of the clamp block, and the positioning column is retracted to the bottom of the turntable, and the workpiece is rotated by the rotation of the turntable. At the same time, the movable table moves and adjusts according to the preset moving distance until the next eccentric hole to be processed corresponds to the positioning column, triggering the extension of the positioning column and the insertion of the eccentric hole until it extends to the upper limit position, triggering the two clamp blocks to clamp the workpiece again, repeating the above processing steps until all the annular grooves are processed according to the preset process. After the mobile clamp is reset again, the clamping action of the rotating clamp is no longer triggered, and the loosening action of the two clamp blocks is directly triggered to unload the processed workpiece.

[0024] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
