Description

Technical Field

[0001] The present invention relates to the field of reducer manufacturing, and in particular to a method and system for processing a reducer bracket assembly. Background Art

[0002] The reducer is an important part of the aviation and aerospace transmission system. It can reduce the output speed, increase the torque, and improve the load capacity, thereby achieving an ideal transmission effect. The reducer bracket assembly is a part of the reducer. The interior of the bracket assembly is a thin-walled hollow structure, which is mainly used to accommodate multiple gear structures. The bracket assembly includes a front bracket unit and a rear bracket unit. During the processing, the hole system on the front bracket unit and the rear bracket unit needs to be processed separately. The processed holes can be used to place bearings, and the gears are fixed on the bearings, thereby forming an effective torque transmission system.

[0003] The thin-walled hollow structure of the bracket assembly brings inconvenience to the clamping of the bracket assembly. For example, too much clamping force can easily damage the bracket assembly structure, and too little clamping force can easily cause the bracket assembly to not be fully fixed during processing. On the other hand, it also increases the difficulty of processing. For example, during processing, the bracket assembly is easily deformed due to excessive milling force. During the production process, a specific clamping device can be used to fix the bracket assembly, so as to facilitate the processing of the hole system of the bracket assembly, improve the processing accuracy of the hole system, improve the meshing accuracy of the gears, and improve the product quality of the bracket assembly.

[0058] In this embodiment, the support assembly 02 has the characteristics of thin-walled hollow structure. In the process of processing the support assembly 02, if the clamping force is too large, it is easy to cause the support assembly 02 to deform. If the clamping force is too small, it cannot meet the processing requirements. Therefore, a specific positioning assembly 01 is required for clamping. Figure 2 As shown, the bracket assembly 02 may include a front bracket unit 21, a rear bracket unit 22, and a gear ring unit 23. Figure 2 , Figure 4As shown, the front support unit 21 may include a front support plate 211, a first center hole 212, first peripheral holes 213, and a front support tube 214. The first center hole 212 and the first peripheral holes 213 penetrate the front support plate 211. The first center hole 212 is located at the center of the plate surface of the front support plate 211, and the first peripheral holes 213 are arranged at intervals along the circumference of the first center hole 212. Figure 3 , Figure 4 As shown, the rear support unit 22 may include a first rear support disc 221, a second center hole 222, a second peripheral hole 223, a second rear support disc 224, peripheral teeth 225, and a rear support column 226. The second center hole 222 may penetrate the center position of the first rear support disc 221. The second peripheral hole 223 may penetrate the first rear support disc 221. The second peripheral hole 223 may be arranged at intervals along the circumference of the second center hole 222. One end of the peripheral teeth 225 may be fixedly connected to one side of the first rear support disc 221, and the other end may be fixedly connected to one side of the second rear support disc 224. The peripheral teeth 225 may be arranged at intervals along the circumference of the first rear support disc 221. The center position of one side of the second rear support disc 224 away from the peripheral teeth 225 may be fixedly connected to one end of the rear support column 226. The front support cylinder 214 of the front support unit 21 and the rear support column 226 of the rear support unit 22 may be connected by threads. Since the front bracket unit 21 and the rear bracket unit 22 of the bracket assembly 02 are connected by threads, if the direction of the milling force is opposite to the direction of thread locking during processing, it is easy to cause the thread to loosen, causing the front bracket to shake during processing, affecting the processing accuracy, and even damaging the workpiece and the tool. Therefore, a method for processing the reducer bracket assembly 02 is proposed, such as Figure 1 As shown, the processing method of the reducer bracket assembly 02 may include:

[0059] Step S10, based on the rear bracket unit 22 of the bracket assembly 02 being positioned and clamped on the positioning assembly 01, the positioning assembly 01 can be positioned and clamped on the machine table 31. Since the front bracket cylinder 214 of the front bracket unit 21 and the rear bracket column 226 of the rear bracket unit 22 can be connected by threads, when the rear bracket unit 22 is positioned, the displacement of the front bracket unit 21 of the bracket assembly 02 can be limited to a certain extent.

[0060] Step S20, based on the positioning and clamping of the positioning component 01 on the machine table 31, the tool unit 32 can perform rough milling on the first center hole 212 of the front bracket unit 21 of the bracket component 02. For example, a bottom four-edge milling cutter with a diameter less than half of the first center hole 212 can be selected to perform rough machining on the first center hole 212, and the lower cut can be completed using a spiral milling method, leaving a 0.02mm finishing allowance in the diameter direction. Among them, the machine table 31 and the tool unit 32 can constitute a processing component 03, the machine table 31 can be used for positioning and fixing the positioning component 01, and the tool unit 32 can be used for machining the bracket component 02. The direction of the milling force exerted by the tool unit 32 on the front bracket unit 21 can be the same as the threaded locking direction between the front bracket tube 214 of the front bracket unit 21 and the rear bracket column 226 of the rear bracket unit 22, so that the threaded connection can be prevented from loosening when the tool unit 32 processes the first center hole 212, thereby causing the front bracket unit 21 to shake during the processing, affecting the processing accuracy of the first center hole 212 and the first peripheral hole 213, and even damaging the bracket assembly 02 and the tool unit 32.

[0061] Step S30, based on the completion of the rough milling of the first center hole 212, the tool unit 32 can perform rough milling on the first peripheral hole 213 of the front bracket unit 21 of the bracket assembly 02; for example, a four-edge milling cutter with a diameter less than half of the first peripheral hole 213 can be selected to perform rough machining on the first peripheral hole 213, and the spiral milling method is used to complete the lower cut, and a 0.03mm finishing allowance is reserved in the diameter direction. Since the internal support structure of the first center hole 212 is more stable, the first center hole 212 has better milling stability than the first peripheral hole 213. Therefore, under similar milling parameters, the first peripheral hole 213 can reserve more finishing allowance to eliminate the vibration marks generated during the milling process. Among them, the first peripheral holes 213 can be arranged at intervals along the circumference of the first center hole 212. The first center hole 212, the front bracket tube 214, and the rear bracket column 226 can all be located on the central axis in the vertical direction of the bracket assembly 02. Therefore, the first center hole 212 of the front bracket unit 21 is processed first, which is beneficial to further tighten the threads between the front bracket unit 21 and the rear bracket unit 22 through milling force. Then the first circumferential hole 213 of the front bracket unit 21 is processed, which can reduce the possibility of relative movement between the front bracket unit 21 and the rear bracket unit 22 during the processing of the first circumferential hole 213, which is beneficial to improve the processing accuracy.

[0062] Step S40, based on the completion of the rough milling of the first peripheral hole 213, the tool unit 32 can perform milling finishing on the first peripheral hole 213 and the first center hole 212 respectively. For example, a six-blade milling cutter with a bottom diameter of one-half to two-thirds of the diameter of the first center hole 212 and the first peripheral hole 213 can be selected for finishing, and the interpolation arc milling method can be used instead of the spiral milling method. Compared with a four-blade milling cutter, the use of a six-blade milling cutter has a shallower spiral groove in structure, better rigidity of the tool, and smoother milling, which can effectively avoid the generation of vibration marks; and the change in the finishing method can make the milling surface smoother and more continuous, which can reduce the vibration of the tool unit 32 and improve the processing stability.

[0063] In step S50 , based on the completion of the milling finishing of the first peripheral hole 213 and the first central hole 212 , the tool unit 32 may perform milling processing on the rear support unit 22 .

[0064] In other embodiments, the gear ring unit 23 may include a first gear ring 231 and a second gear ring 232. The first gear ring 231 may be annular, and gear teeth may be distributed on the inner wall of the first gear ring 231; the second gear ring 232 may be a tapered ring, and gear teeth may be distributed on the inner wall of the second gear ring 232; the end with a larger diameter of the second gear ring 232 may be fixedly connected to the first gear ring 231, and the other end may abut against the second rear support plate 224 of the rear support unit 22. The gear ring unit 23 may be sleeved on the outer circumference of the front support unit 21.

[0065] In this embodiment, step S40 may include:

[0066] In step S41 , based on the completion of the rough milling of the first peripheral side hole 213 , the tool unit 32 may perform fine milling on the first peripheral side hole 213 .

[0067] Step S42, based on the completion of the milling finish machining of the first peripheral hole 213, the tool unit 32 can mill the first center hole 212. In the process of finishing the first center hole 212 and the first peripheral hole 213 of the front bracket unit 21, since the bracket assembly 02 is a thin-walled structure, the first center hole 212 has better support stability than the first peripheral hole 213. By machining the first peripheral hole 213 first and then the first center hole 212, the risk of the hole wall of the first center hole 212 being broken can be reduced, while ensuring the calibration accuracy of the first center hole 212 as the center origin of all machining hole systems.

[0068] In this embodiment, step S10 may include:

[0069] Step S11, based on the positioning requirement of the bracket assembly 02, the first positioning unit 11 of the positioning assembly 01 can position and fix the ring gear unit 23 of the bracket assembly 02 in a first state. Figure 4 As shown, the bracket assembly 02 may include a front bracket unit 21, a rear bracket unit 22, and a ring gear unit 23. The front bracket unit 21 may include a front bracket tube 214, and the rear bracket unit 22 may include a rear bracket column 226. The front bracket tube 214 and the rear bracket column 226 may be threadedly connected, so that one end of the front bracket unit 21 is threadedly connected to one end of the rear bracket unit 22. The inner circumferential wall of the ring gear unit 23 may be spaced apart from the outer circumferential wall of the front bracket unit 21. One end of the ring gear unit 23 may abut against one end of the rear bracket unit 22 close to the front bracket unit 21, so that the rear bracket unit 22 may limit the vertical downward displacement of the ring gear unit 23. The ring gear unit 23 is movable relative to the front bracket unit 21, so the ring gear unit 23 needs to be positioned and fixed to avoid the ring gear unit 23 from being offset during the machining of the bracket assembly 02 and affecting the machining accuracy. As shown Figure 6 As shown, the first positioning unit 11 may include a positioning plate 111 and a positioning rod 112. The positioning plate 111 may be used to position the ring gear unit 23 of the auxiliary bracket assembly 02. Figure 8 As shown, the positioning plate 111 may include a plate body 1111 and a first positioning hole 1112. The first positioning hole 1112 may penetrate the plate body 1111. The first positioning holes 1112 may be arranged on the plate body 1111 at intervals along the circumferential direction of the center of the plate body 1111. Fig. 9As shown, the positioning rod 112 may include a rod body 1121 and a first positioning column 1122. One end of the first positioning column 1122 may be detachably connected to the rod body 1121, and the other end may extend in a direction away from the rod body 1121. The number of the first positioning columns 1122 may be two, and the first positioning columns 1122 may be arranged on the rod body 1121 at intervals along the length direction of the rod body 1121. The diameters of the first positioning column 1122, the first positioning hole 1112, and the first peripheral hole 213 are all matched, and the first positioning column 1122 may pass through the first positioning hole 1112 and the first peripheral hole 213 in sequence, so that the states of the first positioning hole 1112 and the first peripheral hole 213 can be limited by the two first positioning columns 1122 on the positioning rod 112, and the movement or rotation of the front bracket unit 21 and the positioning plate 111 in the horizontal direction can be limited. The first state can include the outer circumferential wall of the disk body 1111 abutting against the inner circumferential wall of the ring gear unit 23, and one end of the first positioning column 1122 can pass through the first positioning hole 1112 and the first circumferential hole 213 of the front bracket unit 21 in sequence. The two first positioning columns 1122 of the positioning rod 112 can be used in conjunction to limit the vertical center axis coincidence between the positioning disk 111 and the first positioning unit 11 and the front bracket unit 21, thereby limiting the vertical center axis coincidence between the ring gear unit 23 and the first positioning unit 11 and the front bracket unit 21, thereby achieving the positioning of the ring gear unit 23 before fixation, and then the ring gear unit 23 can be fixed to the rear bracket unit 22 of the bracket assembly 02 by a detachable connection, thereby avoiding relative movement between the ring gear unit 23 and the front bracket unit 21 and the rear bracket unit 22 during processing, thereby ensuring the smooth progress of the processing.

[0070] Step S12 , based on the first positioning unit 11 completing the positioning and fixing of the ring gear unit 23 in the first state, the second positioning unit 12 of the positioning assembly 01 positions and fixes the bracket assembly 02 .

[0071] In other embodiments, the outer circumferential wall of the disk body 1111 abuts against the inner circumferential wall of the ring gear unit 23. After the ring gear unit 23 is positioned before being fixed by the disk body 1111, the ring gear unit 23 and the rear bracket unit 22 are fixed by a detachable connection. When the detachable connection is made, the milling position of the bracket assembly 02 is avoided, that is, the front bracket unit 21 and the first rear bracket disk 221 are avoided. The detachable connection method is not limited and can be selected according to actual needs. For example, the ring gear unit 23 can be positioned and fixed by using a cable tie, a clamping device, etc. Figure 2 , Figure 3As shown, the outer peripheral wall of the gear ring unit 23 is provided with first holes arranged evenly at intervals along its circumferential direction, and there are at least two symmetrically arranged holes. When the gear ring unit 23 and the rear bracket unit 22 are fixed, one end of the cable tie can be passed through the holes on the second rear bracket plate 224 of the gear ring unit 23 and the rear bracket unit 22 in turn, and the pull head of the cable tie can be fixed on the side of the second rear bracket plate 224 away from the gear ring unit 23, so as to complete the preliminary binding. Subsequently, the positioning plate 111 and the positioning rod 112 can be disassembled and taken out, and then a plurality of cable ties can be tied at intervals along the circumferential direction of the gear ring unit 23. At this time, one end of the cable tie can be passed through the spacing area between the gear ring unit 23 and the front bracket unit 21 and the holes on the second rear bracket plate 224 in turn to complete the binding and fixing, so that the gear ring unit 23 and the front bracket unit 21 maintain a relatively fixed position relationship. After the cable tie is tied and fixed, the excess part can be cut to avoid affecting the milling process of the bracket assembly 02. The projection of the clamping device does not overlap with the projection of the front bracket unit 21.

[0072] In this embodiment, step S12 may include:

[0073] Step S121: Based on the first positioning unit 11 completing the positioning and fixing of the ring gear unit 23 in the first state, the bracket assembly 02 can be placed in the second positioning unit 12 of the positioning assembly 01. Fig.11 As shown, the processing assembly 03 may include a machine table 31 and a tool unit 32, and the second positioning unit 12 is more easily positioned and fixed on the machine table 31. The support assembly 02 is fixed on the second positioning unit 12, so that the tool unit 32 can process the support assembly 02. Figure 5 , Figure 7As shown, the second positioning unit 12 may include a positioning seat 121, a tightening ring 122, a clamping ring 123, and a clamping block 124. The positioning seat 121 is the main body of the second positioning unit 12, the tightening ring 122 can be used to limit the horizontal displacement of the bracket assembly 02, and the clamping ring 123 and the clamping block 124 cooperate to limit the vertical displacement of the bracket assembly 02. The positioning seat 121 may include a seat body 1211, a second positioning hole 1212, an avoidance hole 1213, a tightening screw hole 1214, a limiting groove 1215, and a third positioning hole 1216. The seat body 1211 is the main part of the positioning seat 121. The second positioning hole 1212 can be used to place the bracket assembly 02. When the bracket assembly 02 is placed in the second positioning hole 1212, part of the bracket assembly 02 can be located in the avoidance hole 1213. Bolts of appropriate size can squeeze the clamping ring 123 through the tightening screw hole 1214, thereby limiting the horizontal displacement of the bracket assembly 02. The limiting groove 1215 can be used to fix the clamping block 124. The third positioning hole 1216 can cooperate with the second positioning column 1123 on the positioning rod 112 to achieve the fixation of the positioning rod 112. One end of the second positioning hole 1212 is connected to one end of the avoidance hole 1213. The second positioning hole 1212 and the avoidance hole 1213 penetrate the seat body 1211 in sequence. The diameter of the avoidance hole 1213 is slightly smaller than the second positioning hole 1212, so that a stepped step can be formed at the junction of the second positioning hole 1212 and the avoidance hole 1213. The plane where the upper surface of the stepped step is located can be used as a standard reference plane for the bracket assembly 02, so as to provide a horizontal positioning reference for the processing of the bracket assembly 02. The outer peripheral wall of the tightening ring 122 abuts against the inner peripheral wall of the second positioning hole 1212 near the avoidance hole 1213. The tightening screw hole 1214 penetrates from the outer peripheral side of the seat body 1211 along the radial direction of the seat body 1211 to communicate with the second positioning hole 1212. The opening of one end of the tightening screw hole 1214 near the second positioning hole 1212 is located in the outer peripheral wall area of ​​the tightening ring 122. The tightening ring 122 is an open ring with a certain width. When positioning, the tightening ring 122 and the bracket assembly 02 can be placed simultaneously on a stepped step formed at the junction of the second positioning hole 1212 and the avoidance hole 1213 in the second positioning hole 1212 of the positioning seat 121. The tightening ring 122 is spaced or partially abutted against the peripheral side teeth 225 of the bracket assembly 02. The bolt can abut against the tightening ring 122 through the tightening screw hole 1214. By adjusting the bolt, the tightening ring 122 can be squeezed so that the tightening ring 122 and the peripheral side teeth 225 of the bracket assembly 02 are closely abutted to limit the displacement of the peripheral side teeth 225 in the horizontal direction; at the same time, the inner wall of the tightening ring 122 abuts against the peripheral side teeth 225, and the contact area is larger, which can reduce the pressure on the peripheral side teeth 225 and protect the peripheral side teeth 225 from damage. The limiting grooves 1215 may be arranged at intervals along the circumference of the second positioning hole 1212 at an end of the seat body 1211 away from the avoidance hole 1213 .The limiting groove 1215 can be recessed from one end of the seat body 1211 toward the other end close to the seat body 1211. The limiting groove 1215 is connected to the second positioning hole 1212. The third positioning hole 1216 can be symmetrically arranged on an end face of the seat body 1211 away from the avoidance hole 1213. The third positioning hole 1216 can be located in the area between two adjacent limiting grooves 1215. The third positioning hole 1216 can cooperate with the second positioning column 1123 on the positioning rod 112 to achieve the fixation of the positioning rod 112 on the positioning seat 121, so that the positions of the central axes of the first positioning unit 11 and the second positioning unit 12 in the vertical direction coincide, so that the first positioning unit 11 and the second positioning unit 12 have the same positioning reference, which is convenient for positioning the bracket assembly 02. Such as. Fig.10 As shown, the clamping ring 123 may include a ring body 1231 and a clamping groove 1232. The clamping groove 1232 may be arranged at intervals on one side of the ring body 1231. The clamping groove 1232 may be recessed from one side of the ring body 1231 toward the direction close to the other side of the ring body 1231. The outer peripheral wall of the ring body 1231 may abut against the inner peripheral wall of the second positioning hole 1212 close to the limiting groove 1215. The side of the ring body 1231 away from the clamping groove 1232 may abut against the side of the second rear support plate 224 away from the peripheral side teeth 225. One end of the clamping block 124 abuts against the clamping groove 1232, and the other end is detachably connected to the limiting groove 1215. The width of the clamping block 124 matches the width of the limiting groove 1215 and the clamping groove 1232. The clamping block 124 cooperates with the positioning seat 121 to limit the displacement of the clamping groove 1232 in the vertical direction, thereby limiting the displacement of the bracket assembly 02 in the vertical direction. The first state also includes the end of the second positioning column 1123 away from the rod body 1121 extending into the third positioning hole 1216, so that the central axis of the bracket assembly 02 can coincide with the central axis of the first positioning unit 11 and the second positioning unit 12 in the vertical direction, so as to realize the positioning of the bracket assembly 02 by the first positioning unit 11 and the second positioning unit 12, and ensure the processing accuracy. When the bracket assembly 02 is placed in the second positioning unit 12 of the positioning assembly 01, the bracket assembly 02 is located in the space formed by the second positioning hole 1212 and the avoidance hole 1213, and the side of the fixed connection between the peripheral side teeth 225 and the first rear bracket plate 221 away from the front bracket unit 21 is in contact with the step-shaped step formed at the junction of the second positioning hole 1212 and the avoidance hole 1213. Thus, the downward displacement of the bracket assembly 02 in the vertical direction can be limited.

[0074] Step S122, based on the bracket assembly 02 being placed in the second positioning unit 12, the inner peripheral wall of the tightening ring 122 of the second positioning unit 12 can abut against the outer peripheral wall of the peripheral side teeth 225 of the rear bracket unit 22, thereby limiting the displacement of the rear bracket unit 22 in the horizontal direction. Figure 3 , Figure 4As shown, the rear support unit 22 may include a first rear support disc 221, a second center hole 222, a second circumferential hole 223, a second rear support disc 224, circumferential teeth 225, and a rear support column 226. The second center hole 222 may penetrate the center position of the first rear support disc 221. The second circumferential hole 223 may penetrate the first rear support disc 221. The second circumferential holes 223 may be arranged at intervals along the circumference of the second center hole 222. One end of the circumferential teeth 225 may be fixedly connected to one side of the first rear support disc 221, and the other end may be fixedly connected to one side of the second rear support disc 224. The circumferential teeth 225 may be arranged at intervals along the circumference of the first rear support disc 221. The center position of one side of the second rear support disc 224 away from the circumferential teeth 225 may be fixedly connected to one end of the rear support column 226.

[0075] Step S123, based on the inner circumferential wall of the tightening ring 122 abutting against the outer circumferential wall of the circumferential side teeth 225, one end of the clamping ring 123 of the second positioning unit 12 abuts against one side of the second rear support plate 224 of the rear support unit 22. The clamping ring 123 is convenient for limiting the vertical upward movement of the rear support unit 22.

[0076] Step S124, based on one end of the clamping ring 123 abutting against one side of the rear support plate, align the clamping groove 1232 of the clamping ring 123 with the limiting groove 1215 of the positioning seat 121 of the second positioning unit 12 and put the clamping block 124 into it. Figure 5 As shown, one end of the clamping block 124 of the second positioning unit 12 abuts against the clamping groove 1232, and the other end is detachably connected to the limiting groove 1215. The clamping block 124 cooperates with the positioning seat 121 to limit the vertical upward movement of the clamping ring 123, thereby limiting the vertical upward movement of the rear bracket unit 22.

[0077] Step S125, based on the alignment of the pressing groove 1232 and the limiting groove 1215 and the insertion of the pressing block 124, the first positioning unit 11 is separated from the bracket assembly 02 and the second positioning unit 12 completes the positioning and fixing of the bracket assembly 02. Figure 5As shown, the positioning plate 111 and the positioning rod 112 of the first positioning unit 11 can be removed from the second positioning unit 12 and the bracket assembly 02 after completing the auxiliary positioning, so as to avoid blocking the milling tool 322 during the subsequent milling process of the bracket assembly 02 and affecting the flipping, positioning and clamping of the second positioning unit 12. Through the above steps, the first center hole 212 and the first circumferential side hole 213 on the front bracket unit 21 can maintain a relatively fixed position relationship with the second positioning unit 12. The horizontal displacement of the rear bracket unit 22 is limited by the tightening ring 122, and the vertical displacement of the rear bracket unit 22 is limited by the clamping ring 123 and the clamping block 124 in cooperation with the positioning seat 121, thereby realizing the positioning and fixation of the rear bracket unit 22. The auxiliary positioning of the front bracket unit 21 by the first positioning unit 11 realizes the positioning and fixation of the bracket assembly 02.

[0078] In this embodiment, step S121 may include:

[0079] Step S1211, based on the first positioning unit 11 completing the positioning and fixing of the ring gear unit 23 in the first state, the disc body 1111 can be taken out and one end of the first positioning column 1122 can be inserted into the first peripheral hole 213. Thus, the first positioning unit 11 can be made to coincide with the central axis of the bracket assembly 02 in the vertical direction, and the bracket assembly 02 can be positioned by the first positioning unit 11.

[0080] Step S1212, based on taking out the disk body 1111 and extending one end of the first positioning column 1122 into the first peripheral hole 213, the bracket assembly 02 can be placed in the second positioning unit 12 of the positioning assembly 01 and the second positioning column 1123 of the positioning rod 112 can be extended into the third positioning hole 1216 of the positioning seat 121 of the second positioning unit 12. In this way, the central axes of the bracket assembly 02, the first positioning unit 11, and the second positioning unit 12 in the vertical direction can be overlapped, so that the first positioning unit 11 and the second positioning unit 12 have the same positioning reference. Through the auxiliary positioning of the first positioning unit 11 and the positioning clamping of the second positioning unit 12, the movement or rotation of the positioning assembly 01 in the horizontal direction can be limited, thereby limiting the movement of the bracket assembly 02 in the horizontal direction, facilitating the subsequent processing of the bracket assembly 02 and improving the processing accuracy.

[0081] In this embodiment, step S20 may include:

[0082] In step S21 , based on the rough milling of the first center hole 212 by the tool unit 32 , the tool unit 32 may move to a set position in a direction close to the rear support unit 22 .

[0083] In step S22 , based on the tool unit 32 moving to the set position, the tool unit 32 is controlled to stop the feed milling.

[0084] Step S23, based on the tool unit 32 stopping the feed milling, the tool unit 32 keeps rotating and rotates along the circumference of the first center hole 212 for a set time. After the tool mills to the set position, the milling amount is kept at 0 and idles for a certain time, so that the front bracket unit 21 and the rear bracket unit 22 can be further threaded and locked to prevent the thread from loosening and affecting the processing accuracy. And the surface smoothness of the first center hole 212 can be increased.

[0085] In this embodiment, the milling finishing allowance of the first peripheral hole 213 in step S41 is greater than the first set value; the milling finishing allowance of the first center hole 212 in step S42 is greater than the second set value. When finishing the front bracket unit 21, the first peripheral hole 213 is first processed and then the first center hole 212 is processed, which can ensure the correction accuracy of the first center hole 212 as the center origin of all processing hole systems, thereby ensuring the center correction accuracy of the second center hole 222 after the positioning component 01 is turned over. By setting the finishing allowance reserved for the first center hole 212 to be greater than the set value, the support stability of the first center hole 212 is better, and it is also convenient to eliminate the vibration marks generated when milling the first peripheral hole 213; the finishing allowance reserved for the first peripheral hole 213 is greater than the set value, so that the first peripheral hole 213 has sufficient processing allowance to eliminate the vibration marks generated by milling.

[0086] In this embodiment, step S50 may include:

[0087] Step S51, based on the tool unit 32, the rear support unit 22 is milled, and the positioning component 01 and the support component 02 can be turned over and positioned and clamped on the machine table 31; Fig.11As shown, the processing assembly 03 may include a machine table 31 and a tool unit 32. The machine table 31 may include a frame 311, a processing table 312, and a stop block 313. One end of the frame 311 may be fixedly connected to one side of the processing table 312, and the other end may extend in a direction away from the processing table 312. The processing table 312 may be used to support the positioning assembly 01 and the stop block 313. The stop block 313 may be detachably connected to a side of the processing table 312 close to the frame 311. The stop blocks 313 may be arranged at intervals on the processing table 312. The axis of one of the two adjacent stop blocks 313 in the length direction is perpendicular to the axis of the other stop block 313 in the length direction. The stop block 313 abuts against the outer peripheral wall of the positioning assembly 01, so that the positioning assembly 01 can be positioned on the processing table 312 through the stop block 313. One end of the positioning assembly 01 is detachably connected to the processing table 312. One end of the tool unit 32 is detachably connected to one end of the frame 311 away from the processing table 312, and the other end extends in a direction close to the processing table 312. The tool unit 32 can be used to perform rough milling and fine milling on the bracket assembly 02. When the processing of the current bracket unit 21 is completed, the second positioning unit 12 of the positioning assembly 01 is flipped together with the bracket assembly 02, so that the other end of the positioning assembly 01 is detachably connected to the processing table 312, and the two limit blocks 313 are fully abutted against the outer peripheral wall of the positioning assembly 01, so that the central axis of the bracket assembly 02 in the vertical direction remains unchanged before and after the second positioning unit 12 of the positioning assembly 01 is flipped, which is convenient for processing the rear bracket unit 22.

[0088] Step S52, based on the second positioning unit 12 of the positioning component 01 and the bracket component 02 being flipped and positioned and clamped on the machine table 31, the tool unit 32 can perform milling rough processing and milling finishing on the second peripheral hole 223 of the rear bracket unit 22 in sequence. For example, a bottom four-edge milling cutter with a size less than half of the diameter of the second peripheral hole 223 can be selected for rough processing, and the lower cut can be completed using the spiral milling method, leaving a finishing allowance of 0.03mm in the diameter direction. Since the support structure stability of the second center hole 222 is worse, more finishing allowance can be reserved in the processing of the second peripheral hole 223 to facilitate the elimination of vibration marks caused by milling. When the second peripheral hole 223 is finished, a bottom six-edge milling cutter with a size of one-half to two-thirds of the diameter of the second peripheral hole 223 can be selected for finishing, and the lower cut method of the spiral milling can be replaced with an interpolation arc milling method, so that the milling surface is smoother and continuous, which can reduce the vibration of the tool unit 32 and improve the processing stability.

[0089] Step S53, based on the second peripheral hole 223, the rough milling and the fine milling are sequentially completed, and the tool unit 32 can sequentially perform rough milling and fine milling on the second center hole 222 of the rear support unit 22. Since the support stability of the second center hole 222 of the rear support unit 22 is poorer than that of the second peripheral hole 223, the processing accuracy of the second center hole 222 can be better guaranteed by first processing the second peripheral hole 223 and then processing the second center hole 222.

The first positioning columns 1122 may be arranged on the rod body 1121 at intervals along the length direction of the rod body 1121. The diameter of the first positioning column 1122 matches the diameter of the first circumferential hole 213 and the first positioning hole 1112. One end of the second positioning column 1123 may be detachably connected to the rod body 1121, and the other end may extend in a direction away from the rod body 1121. The number of the second positioning columns 1123 may be two, and the two second positioning columns 1123 may be arranged at both ends of the rod body 1121, respectively. The first positioning column 1122 can pass through the first positioning hole 1112 and the first circumferential hole 213 in sequence, so that the states of the first positioning hole 1112 and the first circumferential hole 213 can be limited by the two first positioning columns 1122 on the positioning rod 112, and the horizontal movement or rotation of the front bracket unit 21 and the positioning plate 111 can be limited.

[0095] The first positioning unit 11 may also include a first state. The first state may include that the outer peripheral wall of the disk body 1111 abuts against the inner peripheral wall of the ring gear unit 23, one end of the first positioning column 1122 passes through the first positioning hole 1112 and the first peripheral hole 213 of the front bracket unit 21 in sequence, and the ring gear unit 23 is detachably connected to the rear bracket unit 22 of the bracket assembly 02. When the first positioning unit 11 is in the first state, the two first positioning columns 1122 of the positioning rod 112 can limit the displacement or rotation of the positioning disk 111 in the horizontal direction, and limit the positioning disk 111 to be at the center position of the front bracket unit 21 in the vertical direction; the outer peripheral wall of the disk body 1111 of the positioning disk 111 abuts against the inner peripheral wall of the ring gear unit 23, thereby limiting the displacement of the ring gear unit 23 in the horizontal direction, and limiting the central axis position of the ring gear unit 23 to coincide with the center position of the front bracket unit 21. In the first state, the ring gear unit 23 can be detachably connected to the rear bracket unit 22 of the bracket assembly 02, so as to limit the displacement of the ring gear unit 23 and position and fix the ring gear unit 23.

[0096] like Figure 5 , Figure 7As shown, the second positioning unit 12 may include a positioning seat 121, a tightening ring 122, a clamping ring 123, and a clamping block 124. The positioning seat 121 is the main body of the second positioning unit 12, the tightening ring 122 can be used to limit the horizontal displacement of the bracket assembly 02, and the clamping ring 123 and the clamping block 124 cooperate to limit the vertical displacement of the bracket assembly 02. The positioning seat 121 may include a seat body 1211, a second positioning hole 1212, an avoidance hole 1213, a tightening screw hole 1214, a limiting groove 1215, and a third positioning hole 1216. The seat body 1211 is the main part of the positioning seat 121. The second positioning hole 1212 can be used to place the bracket assembly 02. When the bracket assembly 02 is placed in the second positioning hole 1212, part of the bracket assembly 02 can be located in the avoidance hole 1213. Bolts of appropriate size can squeeze the clamping ring 123 through the tightening screw hole 1214, thereby limiting the horizontal displacement of the bracket assembly 02. The limiting groove 1215 can be used to fix the clamping block 124. The third positioning hole 1216 can cooperate with the second positioning column 1123 on the positioning rod 112 to achieve the fixation of the positioning rod 112. One end of the second positioning hole 1212 is connected to one end of the avoidance hole 1213. The second positioning hole 1212 and the avoidance hole 1213 penetrate the seat body 1211 in sequence. The diameter of the avoidance hole 1213 is slightly smaller than the second positioning hole 1212, so that a stepped step can be formed at the junction of the second positioning hole 1212 and the avoidance hole 1213. The plane where the upper surface of the stepped step is located can be used as the standard reference plane of the bracket assembly 02. When the positioning assembly 01 is positioned and fixed on the machine table 31, the standard reference plane is in a horizontal state, and the processing reference plane coincides with the standard reference plane, so that it is convenient to process the bracket assembly 02. Among them, the processing reference plane is obtained by processing the plane on the side of the first rear bracket disc 221 away from the front bracket tube 214, and the processing reference plane is perpendicular to the central axis of the bracket assembly 02 in the vertical direction. The outer peripheral wall of the tightening ring 122 abuts against the inner peripheral wall of the second positioning hole 1212 close to the avoidance hole 1213. The tightening screw hole 1214 penetrates from the outer peripheral side of the seat body 1211 along the radial direction of the seat body 1211 to communicate with the second positioning hole 1212. The tightening screw hole 1214 has an opening at one end close to the second positioning hole 1212 and is located in the outer peripheral wall area of ​​the tightening ring 122. The tightening ring 122 is an open ring with a certain width. When positioning, the tightening ring 122 and the bracket assembly 02 can be placed simultaneously on a stepped step formed at the junction of the second positioning hole 1212 and the avoidance hole 1213 in the second positioning hole 1212 of the positioning seat 121. The tightening ring 122 and the peripheral side teeth 225 of the bracket assembly 02 are arranged at intervals or partially abutted.The bolt can be abutted against the tightening ring 122 through the tightening screw hole 1214. By adjusting the bolt, the tightening ring 122 can be squeezed so that the tightening ring 122 is closely abutted against the peripheral teeth 225 of the bracket assembly 02 to limit the displacement of the peripheral teeth 225 in the horizontal direction; at the same time, the inner wall of the tightening ring 122 abuts against the peripheral teeth 225, and the contact area is larger, which can reduce the pressure on the peripheral teeth 225 and protect the peripheral teeth 225 from damage. The limiting groove 1215 can be arranged at an end of the seat body 1211 away from the avoidance hole 1213 along the peripheral side of the second positioning hole 1212. The limiting groove 1215 can be recessed from one end of the seat body 1211 toward the other end close to the seat body 1211. The limiting groove 1215 is connected to the second positioning hole 1212. The third positioning hole 1216 can be symmetrically arranged on the end surface of the seat body 1211 away from the avoidance hole 1213. The third positioning hole 1216 can be located in the area between two adjacent limiting grooves 1215. The third positioning hole 1216 can cooperate with the second positioning column 1123 on the positioning rod 112 to fix the positioning rod 112 on the positioning seat 121, so that the positions of the central axes of the first positioning unit 11 and the second positioning unit 12 in the vertical direction coincide with each other, so that the first positioning unit 11 and the second positioning unit 12 have the same positioning reference, which is convenient for positioning the bracket assembly 02. Fig.10 As shown, the clamping ring 123 may include a ring body 1231 and a clamping groove 1232. The clamping groove 1232 may be arranged at intervals on one side of the ring body 1231. The clamping groove 1232 may be recessed from one side of the ring body 1231 toward the direction close to the other side of the ring body 1231. The outer peripheral wall of the ring body 1231 may abut against the inner peripheral wall of the second positioning hole 1212 close to the limiting groove 1215. The side of the ring body 1231 away from the clamping groove 1232 may abut against the side of the second rear support plate 224 away from the peripheral side teeth 225. One end of the clamping block 124 abuts against the clamping groove 1232, and the other end is detachably connected to the limiting groove 1215. The width of the clamping block 124 is adapted to the width of the limiting groove 1215 and the clamping groove 1232. The clamping block 124 cooperates with the positioning seat 121 to limit the displacement of the clamping groove 1232 in the vertical direction, thereby limiting the displacement of the bracket assembly 02 in the vertical direction. The first state also includes the end of the second positioning column 1123 away from the rod body 1121 extending into the third positioning hole 1216, so that the central axis of the bracket assembly 02 can coincide with the central axis of the first positioning unit 11 and the second positioning unit 12 in the vertical direction, so that the first positioning unit 11 and the second positioning unit 12 have the same positioning reference. The first positioning unit 11 and the second positioning unit 12 can limit the movement or rotation of the positioning assembly 01 in the horizontal direction, thereby limiting the movement of the bracket assembly 02 in the horizontal direction, facilitating the processing of the bracket assembly 02 and improving the processing accuracy.

[0097] In other embodiments, without affecting the overall performance, a plurality of weight-reducing grooves may be provided on the positioning seat 121 of the positioning assembly 01, thereby making it lighter and easier to operate.

[0098] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present disclosure.
