Description

Technical Field

[0001] The utility model relates to the technical field of spinning assembly processing, in particular to a spinning assembly step surface processing device. Background Art

[0002] The spinning assembly has high requirements for the processing accuracy of parts. Some parts need to process multiple step surfaces with arc trajectories on their surfaces. Since the multiple step surfaces are formed in a circular shape and the position status of each segment is different, if a conventional milling machine is used for fixed clamping, it is difficult to program the running trajectory of the props. If the shapes and sizes of multiple step surfaces are consistent, the workpiece angle can be adjusted by multiple clamping to repeat the processing trajectory of a single step surface. Even so, the writing of a single trajectory is still relatively complicated, and repeated clamping is also troublesome, which seriously affects the processing efficiency. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a spinning assembly step surface processing device to simplify the processing trajectory of the segmented arc step surface and improve processing efficiency.

[0007] A milling mechanism is arranged horizontally above the turntable, and an identification module is arranged at a fixed position above the turntable. When the turntable rotates so that the positioning unit corresponds to the position of the identification module, the boundary line of one end of the area to be processed corresponding to the milling mechanism and the identification module coincides.

[0008] Furthermore, the positioning unit is configured as a positioning column, and the workpiece is provided with a positioning hole corresponding to and inserted into the positioning column.

[0009] Furthermore, the axes of the plurality of positioning posts are parallel to the central axis of the turntable and are arranged at equal intervals.

[0011] Furthermore, the milling mechanism is slidably arranged on a transverse guide rail, the transverse guide rail is located on one side of the identification module, and is rotatably arranged around the identification module.

[0012] Furthermore, the positioning hole is located between two adjacent areas to be processed, and the vertical distance between the positioning hole and the adjacent boundary line of the corresponding area to be processed is fixed, and the distance is consistent with the vertical distance between the identification module and the transverse guide rail.

[0013] Beneficial effects: The utility model provides a spinning assembly step surface processing device, which realizes the cleaning processing of a single arc-shaped step surface through the cooperation of the turntable rotation and the lateral movement of the milling mechanism; through the turntable rotation and the identification module to identify and position the positioning unit, it realizes the switching between multiple arc-shaped step surface processing areas and the positioning of the tool starting point, so that the processing of multiple step surfaces can be quickly connected, and the processing efficiency is effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 The figure is a schematic structural diagram of an embodiment of a workpiece. DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] As attached Figure 1-2 The spinning assembly step surface processing device comprises a turntable 1, the center of which clamps and fixes a workpiece 2; and the angle of the workpiece can be adjusted by rotating the turntable.

[0018] The workpiece 2 includes a plurality of arc-shaped areas 21 to be processed, and the centers of the plurality of areas 21 to be processed coincide with the central axis of the turntable 1;

[0019] The turntable 1 is provided with a plurality of positioning units 11, and the plurality of positioning units 11 correspond one-to-one to the plurality of areas to be processed 21 respectively;

[0020] A milling mechanism 3 is arranged horizontally above the turntable 1, and an identification module 4 is arranged at a fixed position above the turntable 1. When the turntable 1 rotates so that the positioning unit 11 corresponds to the position of the identification module 4, the boundary line of one end of the area to be processed 21 corresponding to the milling mechanism 3 and the identification module 4 coincides.

[0021] This solution decomposes the milling of the arc-shaped step surface into the milling of multiple concentric arc curves. When processing each arc curve, the milling cutter of the milling mechanism keeps rotating and the overall relative position remains stationary. The workpiece on it is slowly rotated by a certain angle through the rotation of the turntable, so that the milling cutter leaves a processing mark of the expected length on the surface of the workpiece. The milling mechanism only needs to move a certain distance in the direction of the end boundary line of the step surface after completing the processing of each arc curve, and then continue to remain stationary and cooperate with the rotation of the turntable to complete the processing of another arc curve. By setting an identification module for identifying the positioning unit, it is ensured that when processing each arc curve, the landing point of the tool can accurately fall on the end boundary line of the area to be processed, and then the length of each arc curve is determined in conjunction with the rotation angle setting of the turntable, so that the final arc step surface meets the processing requirements. The parameters that need to be designed in the entire process are only the unit distance of the inner layer movement of the milling mechanism and the angle that each layer of the turntable needs to rotate. There is no need for complex tool movement trajectory programming.

[0022] The positioning unit 11 is configured as a positioning post, and the workpiece 2 is provided with a positioning hole 22 corresponding to the positioning post. While serving as a positioning mark for each processing area, it can also facilitate rapid positioning during the workpiece clamping stage, and quickly align the positioning unit with each processing area, effectively improving installation efficiency and making processing easier.

[0023] The axes of the multiple positioning columns are parallel to the central axis of the turntable 1 and are arranged at equal intervals. This eliminates the need to change the position of the identification module. By rotating the turntable, the multiple positioning units can be aligned with the identification module in sequence. After each processing area is completed, the turntable rotates to allow the identification module to identify another positioning unit, allowing the processing of the next step surface to be quickly connected without the need for re-clamping or rewriting the trajectory program, greatly improving processing efficiency. Furthermore, through the positioning of multiple positioning columns, the workpiece can be coaxially arranged relative to the turntable, and then the workpiece can be clamped using hydraulic clamps on the circumference, ensuring the stability of the workpiece during processing and ensuring processing quality.

[0024] The positioning column is detachably connected to the table top of the turntable 1. Preferably, by opening a threaded hole on the turntable and installing the positioning column through threaded cooperation, the limiting column of the installation or removal part can be selected according to the specific size and distribution of the arc step surface on the workpiece to improve applicability.

[0025] The milling mechanism 3 is slidably mounted on a transverse guide rail 5, which is located on one side of the recognition module and rotates around the recognition module 4. Since the end boundary lines of different types of curved step surfaces may extend in different directions, the transverse guide rail is rotated and adjusted based on the upper and lower positions of the positioning unit determined by the recognition module to ensure that the movement direction of the milling mechanism coincides with the preset processing area boundary line.

[0026] The positioning hole 22 is located between two adjacent areas to be processed 21 , and the vertical distance between the positioning hole 22 and the adjacent boundary line of the corresponding area to be processed 21 is fixed, and the distance is consistent with the vertical distance between the identification module 4 and the transverse guide rail 5 .

[0027] In an embodiment, a thrust block of a spinning assembly needs to process multiple step surfaces with arc-shaped trajectories at the edge of a circular cross-section. The multiple step surfaces are as shown in Appendix 1, have the same shape and size, and are evenly arranged around their own centers. The positioning holes thereon are opened at the center position between the boundary lines of the end portions of adjacent step surfaces. Due to the consistency of the multiple step surfaces, when performing processing, the processing of multiple step surfaces located on the same layer of arc curves can be completed first by rotating the turntable one circle. After the turntable rotates one circle, when the positioning unit recognized for the first time is recognized again, the milling mechanism is controlled to move a unit distance, and then the processing is completed for one circle, and so on, until the processing of all step surfaces is completed. During the whole process, the turntable performs periodic angle control rotation adjustment, and the milling mechanism performs fixed distance displacement in the straight line direction. There is no need to program complex trajectories, which reduces the processing difficulty and improves the processing efficiency.

[0028] 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.
