Description

Technical Field

[0001] The invention relates to the technical field of chamfering and tapping, in particular to a chamfering and tapping device for a stator pressure ring of a vertical machining center. Background Art

[0002] The stator clamp is an important structure of the stator component in the motor or generator. Its main function is to fix the stator core and the insulation layer together and ensure the stability of the stator core. The stator clamp is generally made of high-strength materials (such as steel or aluminum alloy). Vertical machining is a method of metal cutting using a vertical machining center. In this equipment, the workpiece is clamped horizontally and the tool moves vertically.

[0003] Specific devices are required for chamfering and tapping the stator pressure ring. These devices are usually used to improve processing efficiency and accuracy and ensure the stability of various processes during the processing. Chamfering is the process of beveling the edge of the workpiece. This can remove sharp edges, reduce stress concentration, and improve the appearance of the workpiece. The chamfering device usually includes a rotating tool or cutter to chamfer the workpiece at a preset angle and depth; tapping is the process of processing threaded holes in the workpiece. The tapping device is usually equipped with a tapping tool that can automatically perform tapping operations on a machining center. Drilling is usually required before tapping, because the tapping process is to cut threads in pre-drilled holes. If there is no pre-hole, the tapper may have difficulty entering the material or cause uneven thread cutting; when processing the stator pressure ring, the chamfering and tapping processes are usually combined. In this operation, the chamfering tool first chamfers the edge or mouth of the hole on the stator pressure ring, and then taps to cut the internal thread.

[0004] At present, the existing technology usually sets the stator pressure ring on a workbench, and uses a chamfering tool and a tapping drill to perform chamfering and tapping processing on the stator pressure ring. During processing, it is necessary to spray cutting fluid on the processing position to prevent problems such as metal powder flying and overheating of the stator pressure ring during processing. However, when the stator pressure ring is replaced, the cutting fluid is still sprayed, which easily causes waste of cutting fluid; therefore, it does not meet the existing needs. We have proposed a vertical machining center for this. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

During the processing, it is necessary to spray cutting fluid on the processing position to prevent metal powder from flying and the stator pressing ring from overheating during the processing. However, when the stator pressing ring is replaced, the cutting fluid is still sprayed, which easily causes the problem of cutting fluid waste. Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8A stator pressure ring chamfering and tapping device for a vertical machining center includes a pressure ring body 1, a machine body 100, and a processing table 110 rotatably arranged on the upper side of the machine body 100, a shaft rod 111 is arranged on the inner side of the machine body 100, and the lower end of the shaft rod 111 is rotatably inserted on the inner side of the machine body 100 through a bearing, a motor 112 is fixedly installed inside the machine body 100, the output shaft of the motor 112 is transmission-connected to the bottom of the shaft rod 111, and the motor 112 is used to drive the processing table 110.

The inner ring of the pressure ring body 1 is opened with a limiting groove 123 used in conjunction with the limiting column 122, and the limiting column 122 is inserted in the limiting groove 123 to prevent the pressure ring body 1 from rotating in the processing groove 120.

[0034] A drill 130 is arranged on the outside of the body 100, and a drill bit 140 is rotatably arranged on the side of the drill 130. A chamferer 150 is installed on the outside of the body 100, and a chamfering tool 160 is rotatably arranged on the side of the chamferer 150. A tapper 170 is also installed on the outside of the body 100, and a tapper head 180 is rotatably arranged on the side of the tapper 170. The number of the drill bit 140, the chamfering tool 160, and the tapping head 180 are all uniformly arranged in the circumferential direction, so as to facilitate the simultaneous drilling, chamfering and tapping of multiple positions on the pressure ring body 1. The drill bit 140, the chamfering tool 160, and the tapping head 180 are all technical means well known to technicians in this field, and they are not elaborated here. The processing table 110 drives the pressure ring body 1 thereon to rotate, and passes under the drill bit 140, under the chamfering tool 160, and under the tapping head 180 in turn.

[0035] Liquid pipes 190 are provided on the sides of the drill 130, the chamfer 150, and the tapper 170, and the ends of the liquid pipes 190 are connected to the first nozzles 200. The liquid pipes 190 include annular tubes 191 fixedly mounted on the outsides of the drill 130, the chamfer 150, and the tapper 170, and straight tubes 192 installed on the outside of the body 100 and connected to the annular tube 191. The first nozzles 200 are connected to the annular tube 191. The number of the first nozzles 200 is set to be several, and the first nozzles 200 are connected to the annular tube 191. The straight tubes 192 are set to be retractable bellows to facilitate the lifting and lowering of the annular tube 191 and the first nozzles 200. The straight tubes 192 are connected to the cutting fluid, so that the cutting fluid is sprayed on the processing position of the pressure ring body 1 through the first nozzle 200.

[0036] The middle of the liquid pipe 190 is slidably plugged with an adjusting piece 210 for controlling the connection of the liquid pipe 190, and the outer side of the processing table 110 is fixedly installed with a resisting rod 220 for driving the adjusting piece 210. The middle of the straight pipe 192 is fixedly installed with a connecting shell 221, and the side of the adjusting piece 210 is provided with a through hole 222. The side of the connecting shell 221 is slidably plugged with a connecting rod 223, one end of the connecting rod 223 is fixedly connected to the adjusting piece 210, and the other end of the connecting rod 223 is fixedly installed with The wedge block 224 and the connecting shell 221 are provided with a first spring 225 on the inner side, and the two ends of the first spring 225 are respectively fixedly connected to the adjusting piece 210 and the inner wall of the connecting shell 221, and the number of the abutment rods 220 is uniformly arranged in the circumferential direction, and the abutment rods 220 intermittently abut against the wedge block 224, respectively. In the initial state, the through hole 222 is located outside the straight tube 192, so that the straight tube 192 is blocked by the adjusting piece 210, and the abutment rod 220 is away from the wedge block 224.

[0037] In this embodiment: the processing table 110 drives the pressing ring body 1 to rotate to the bottom of the drill bit 140, and the drill 130 drives the drill bit 140 to descend to drill the pressing ring body 1. At the same time, the processing table 110 also drives the resistance rod 220 to approach the wedge block 224 and squeeze the wedge block 224, so that the wedge block 224 drives the adjustment plate 210 to slide through the connecting rod 223, so that the through hole 222 moves into the straight tube 192, and the first spring 225 is compressed, so that the straight tube 192 is connected with the cutting fluid, which is convenient for spraying the cutting fluid to the drilling position of the pressing ring body 1 through the first nozzle 200. After the drilling is completed, the processing table 110 drives the pressing ring body 1 to continue to rotate, so that the resistance rod 220 is away from the wedge block 224, and the squeezing of the wedge block 224 is released. Under the action of the rebound force of the first spring 225, the adjustment plate 210 is driven to reset, and the straight tube 192 is blocked again, thereby stopping the injection of the cutting fluid; Similarly: when the chamfering tool 160 or the tapping head 180 is chamfering or tapping the pressure ring body 1, the cutting fluid is sprayed to the processing position, and when the pressure ring body 1 is in a rotational displacement, the cutting fluid stops spraying, thereby reducing the waste of cutting fluid as much as possible, and solving the problem that the prior art usually sets the stator pressure ring on the workbench, and uses a chamfering tool and a tapping drill bit to chamfer and tap the stator pressure ring respectively, and during processing, it is necessary to spray cutting fluid to the processing position to prevent metal powder from flying during processing and overheating of the stator pressure ring. However, when the stator pressure ring is replaced, the cutting fluid is still sprayed, which easily causes the problem of cutting fluid waste.

[0038] Embodiment 2: This embodiment is intended to solve the problem that when the pressing ring body 1 is moved and processed, it is inconvenient to position the pressing ring body 1, which easily causes the pressing ring body 1 to shift, thereby easily affecting the processing accuracy of the pressing ring body 1.

A pressing block 232 is fixedly installed on the upper end of the positioning rods 230, and the lower ends of the two positioning rods 230 are commonly connected to a second spring 233. A track groove 234 is opened on the upper side of the machine body 100, and the lower ends of the positioning rods 230 are inserted in the track groove. In the groove 234, the track groove 234 is set as an annular groove body with different widths, and the track groove 234 includes a narrow groove 2341 and a wide groove 2342. The narrow groove 2341 and the wide groove 2342 are both set as arc grooves, and one end of the narrow groove 2341 is connected with one end of the wide groove 2342, and the other end of the narrow groove 2341 is connected with the other end of the wide groove 2342. When the lower end of the positioning rod 230 is located in the narrow groove 2341 or the wide groove 2342, the second spring 233 is in a compressed state.

[0039] A disk 240 is fixedly mounted on the upper end of the shaft 111, and an insert shaft 241 is rotatably inserted on the upper side of the disk 240. A second gear 242 is fixedly mounted on the top of the insert shaft 241. A connecting ring 243 is fixedly mounted on the bottom of the processing table 110. The connecting ring 243 is rotatably inserted on the inner side of the machine body 100. The inner ring of the connecting ring 243 is provided with a tooth segment 244. The second gear 242 is intermittently meshed with the tooth segment 244. When the second gear 242 is meshed with the tooth segment 244, the second gear 242 passes through the connecting ring 243. 43 drives the processing table 110 to rotate seventy-two degrees, that is, one-fifth of a circle; a cylinder 250 is fixedly installed inside the body 100, and a piston 251 is slidably arranged inside the cylinder 250. A slot 252 is opened on the side of the disc 240, and the slot 252 is arranged as an annular slot body. The end of the piston 251 is slidably inserted in the slot 252. The slot 252 includes a gradually deepening groove 2521 and a gradually shallowing groove 2522 connected from end to end, and the end of the piston 251 is arranged as a sphere to prevent the piston 251 from escaping from the slot 252.

[0040] A first one-way valve 260 and a second one-way valve 261 are fixedly connected to the side of the cylinder 250, and the end of the first one-way valve 260 is connected to a first air pipe 262 connected to the outside, and the outside air enters the cylinder 250 through the first air pipe 262 and the first one-way valve 260; the end of the second one-way valve 261 is connected to a second air pipe 263 inserted on the upper side of the body 100, and the upper end of the second air pipe 263 is connected to a second nozzle 264, and the air in the cylinder 250 is sprayed out from the second nozzle 264 through the second one-way valve 261 and the second air pipe 263.

[0041] In this embodiment: the motor 112 drives the second gear 242 to intermittently mesh with the tooth segment 244 through the disc 240, so that after the motor 112 drives the disc 240 to rotate one circle, the second gear 242 is meshed with the tooth segment 244, so that the processing table 110 rotates one-fifth of a circle. When the disc 240 rotates, the piston 251 slides in the gradually deepening groove 2521, so that the piston 251 is pulled outward, and the outside air is sucked into the cylinder 250. When the piston 251 slides in the gradually shallow groove 2522, the piston 251 is pushed inward, and the air in the cylinder 250 is sprayed from the second nozzle 264 onto the pressing ring body 1 after the tapping process is completed, so that the cutting fluid remaining on the pressing ring body 1 is blown off; The processing table 110 drives the pressing ring body 1 and the positioning rod 230 to rotate, so that the bottom of the positioning rod 230 slides in the track groove 234. When the pressing ring body 1 is in the section from the drill bit 140 to the tapping head 180, the lower end of the positioning rod 230 is located in the wide groove 2342. Under the action of the rebound force of the second spring 233, the positioning rod 230 is driven to rotate, so that the upper end of the positioning rod 230 drives the pressing block 232 to press down on the pressing ring body 1, thereby fixing the pressing ring body 1. When the pressing ring body 1 is moved and processed, it is convenient to position the pressing ring body 1, and it is not easy to cause the pressing ring body 1 to deviate, thereby improving the processing accuracy of the pressing ring body 1. When the pressure ring body 1 is in the section from the tapping head 180 to the drill bit 140, the lower end of the positioning rod 230 is located in the narrow groove 2341, and the lower ends of the positioning rods 230 are close to each other, so that the upper end of the positioning rods 230 drives the pressure block 232 away from the pressure ring body 1, thereby facilitating the placement and removal of the pressure ring body 1.

[0042] Embodiment 3: This embodiment is intended to promote the solution of the problem that it is inconvenient to chamfer both ends of the hole on the pressure ring body 1, thereby affecting the processing effect.
