Description

Technical Field

[0001] The invention belongs to the field of valve nozzle processing equipment, and in particular relates to a valve nozzle multi-station processing center. Background Art

[0002] The valve is an independent valve body device that allows gas to enter the space of a tubeless tire or inner tube when it is opened, and then automatically closes and seals to preserve the gas and generate air pressure to prevent the gas from escaping the tire or inner tube. In addition to solid tires, other tires or inner tubes that must be inflated need to be inflated using this device. Currently, the valve is directly installed on the inside of the tire and extends outward. When inflation is required, the outer part of the valve is directly used to inflate the tire.

[0003] At present, the processing of valves is all carried out with conventional processing equipment, including lathes, drilling machines, milling machines, and threading equipment. The bottom and top of a valve have size requirements, the internal cavity also has different inner diameter requirements, and the inner cavity and the outside of the valve also have different thread requirements. Although a valve is small, it also requires multiple steps of different processing equipment to process different parts to finally complete the processing of the valve. The processing process is not only cumbersome but also very time-consuming, and the requirements for manual processing proficiency are also very high. Some manufacturers also use automated processing equipment to automatically process part of the valve processing process or part of the space, but it is also necessary to transfer the valve workpiece between different processing equipment, which also takes a lot of time. This is also the reason why the valve is small but the processing cost is not low. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] See also Figure 1-21 The present invention provides a technical solution: a multi-station machining center for valves, the multi-station machining center comprising:

[0069] A base 2 is arranged at the bottom of the multi-station machining center;

[0070] A processing part 1 is arranged on the upper part of the base 2 to process the valve;

[0071] A housing 4 covers the upper part of the processing part 1 and the base 2;

[0072] The control unit 3 is led out through the housing 4 to control the multi-station machining center;

[0073] Base 2 includes:

[0074] The base rotating cylinder 21 is arranged at the bottom of the base 2;

[0075] The base rotating disk 22 is arranged on the upper part of the base rotating cylinder 21 and is driven to rotate by the base rotating cylinder 21;

[0076] The base fixing plate 23 is arranged on the upper part of the base rotating plate 22 and is fixed upward through the center of the base rotating plate 22;

[0077] The base support sliding wheel 24 is arranged at the lower part of the base rotating disk 22 to provide sliding support for the rotation of the base rotating disk 22;

[0078] The processing part 1 includes the following parts which are arranged in sequence along the periphery of the base rotating disk 22:

[0079] The first station 11 introduces the valve into the multi-station machining center and fixes it;

[0080] The second station 12 is used to inspect the valve nozzle loaded at the first station 11;

[0081] The third station 13 uses a die to thread the bottom of the valve;

[0082] The fourth station 14 uses a combined tool to expand the cavity of the valve nozzle;

[0083] The fifth station 15 uses a drill to pre-process the cavity of the valve;

[0084] The sixth workstation 16 uses a combined tool to chamfer and size the valve head internally and externally;

[0085] The seventh station 17, using a die to thread the outer periphery of the upper part of the valve mouth;

[0086] The eighth station 18, using a die to thread the inner side of the upper cavity of the valve mouth;

[0087] The ninth station 19 uses a milling head to perform fine milling on the inner side of the upper cavity of the valve mouth;

[0088] The tenth station 110 uses a combined measuring tool and a blowing device to inspect and blow the valve after processing;

[0089] The eleventh workstation 111 uses a clamp to differentiate and cut the processed valves;

[0090] The twelfth workstation 112 uses an air blower and a brush to perform chip cleaning operations on the workstation.

[0091] The base 2 is a frame structure, providing support for the upper processing part 1 and the outer shell 4. The processing part 1 has a total of twelve processing positions. After the twelve processing positions are processed in sequence, the valve mouth is processed into a finished product with qualified size.

[0092] See Fig.16As shown, the base 2 mainly includes a base rotating cylinder 21 at the bottom, and a circular larger base rotating disk 22 is connected above the base rotating cylinder 21, and can drive it to rotate precisely at a certain angle at intervals, so that the valve mouth reaches the corresponding workstation for processing. A smaller base fixed disk 23 is set in the middle position of the base rotating disk 22. The base fixed disk 23 is fixed by a fixed shaft extending from the middle of the base rotating disk 22, and does not rotate with the rotation of the base rotating disk 22. In order to ensure that the base rotating cylinder 21 can drive the upper base rotating disk 22 and the processing position thereon to rotate, a plurality of groups of base support sliding wheels 24 are set between the base and the base rotating disk 22. The bottom of the base support sliding wheel 24 is fixed on the base 2, and the upper part is a sliding wheel structure, which plays the role of sliding support to ensure the smoothness of the rotation of the base rotating disk 22.

[0093] See Figure 1-3 As shown, according to the requirements of the processing position and processing method of the valve, the processing part 1 is divided into twelve processing positions and arranged around the base rotating disk 22. From the loading end to the unloading end, the different parts of the valve are processed and tested in sequence by rotating, wherein:

[0094] The first workstation 11 is a fixed loading workstation, which is close to the front end of the loader 1101. The loader 1101 lifts the valve nozzle before processing to the position where the first workstation 11 can load materials. A manipulator is used to take the valve nozzle transported by the loader 1101 and fix it on the processing part 1 for subsequent processing.

[0095] The second station 12 is a testing station. After the first station 11 loads and fixes the valve, the valve fixed by the first station 11 is transported to the second station 12 through the rotation of the base rotating disk 22. The valve products are tested accordingly at the second station 12. The valves to be processed that pass the test are qualified products and enter the next station for processing. The unqualified products detected are recorded by the processing center. As the base rotating disk 22 rotates, the subsequent stations will no longer process them until they reach the eleventh station 111 for distinguishing and unloading, and they are classified into the unqualified product unloading area for unloading.

[0096] The third station 13 is the formal processing start station of the machining center, which mainly performs threading on the outer thread at the bottom of the valve mouth, that is, a die of model 12V1 is used to perform threading operation in the third station 13. After threading is completed, the valve mouth continues to rotate one station along with the base rotating disk 22 to reach the fourth station 14.

[0097] The fourth station 14 is a station for processing the upper cavity of the valve. It uses a 3.9mm drill bit to process a step in the upper cavity of the valve, and the drill bit is also equipped with a Fig.19 The peripheral rotating turning tool shown in the figure turns the outside of the valve nozzle while expanding the cavity, and pre-processes the 8V1 external thread processing area in front of the subsequent valve nozzle, thereby saving the subsequent 8V1 threading die. After the processing is completed, the base rotating disk 22 continues to rotate to the next workstation.

[0098] The fifth station 15 is a pre-processing station, and the function of this station is also to process the upper cavity of the valve mouth, that is, to use a 4.7mm drill bit to pre-expand the upper part of the cavity, so as to facilitate the subsequent 5V1 internal thread processing of the eighth station 18, thereby saving the subsequent processing tool loss and achieving the critical processing size. After the processing is completed, the base rotating disk 22 continues to rotate to the next station.

[0099] The sixth station 16 is a fixed-length processing station, which adopts Fig. 20 The combined tooling is used to chamfer and size the inner and outer edges of the valve head, which ensures the high consistency of the valve product. At the same time, the inner and outer edges of the upper part of the valve are chamfered at the same time, and more accurate sizing is performed for the subsequent fine processing of the 5V1 internal thread, which also saves the fine reamer for the subsequent 5V1 processing. After the processing is completed, the base rotating disk 22 continues to rotate to the next station.

[0100] The seventh station 17 is a station for threading the outer thread on the upper part of the valve stem. This station uses an 8V1 die to thread the outer side of the valve stem head. The outer thread of the head is processed first, and then the inner thread of the head is processed in the subsequent station. This is to avoid processing the inner thread first and then the outer thread, which may cause the inner diameter of the valve stem to be reduced during processing. This will cause the valve core to not pass through the inner cavity of the valve stem. After the processing is completed, the base rotating disk 22 continues to rotate to the next station.

[0101] The eighth station 18 is a station for threading the inner side of the upper cavity of the valve. This station uses a 5V1 thread die for processing, and processes a spiral thread structure at a corresponding position on the inner side of the upper part of the valve. After the processing is completed, the base rotating disk 22 continues to rotate to the next station.

[0102] The ninth station 19 is a station for fine milling of the inside of the valve mouth after the 5V1 threading in the eighth station. This station uses a fine milling cutter head to mill the inside of the valve mouth to a certain angle, and can remove the burrs after the processing in the eighth station 18, so that the valve core can enter the valve mouth. Since the ninth station, all the processing processes have been completed, and the subsequent stations are inspection, cleaning and unloading stations. After the processing is completed, the base rotating disk 22 continues to rotate to the next station.

[0103] The tenth station 110 is a testing and purging station, which uses a servo motor to drive a combined measuring tool to test the processed valve. Before testing, the purging tool of this station is used for purging to avoid detection errors. The main purpose is to insert the detection tool into the mold cavity after the valve is processed to detect whether the 3.9mm drill processing depth of the fourth station 14 is qualified, and to detect whether the fine milling operation of the ninth station 19 is in place. After the purging and testing are completed, the base rotating disk 22 continues to rotate to the next station. In addition, in some embodiments, a side blowing device 11007 is also provided at the tenth station 110 for further thorough purging, which can intermittently blow out gas with a certain pressure to purge the lower part of the valve product as a whole.

[0104] The eleventh station 111 is a distinguishing unloading station, which first releases the valve from the station, and then uses the clamp to grab the valve, and distinguishes between qualified products and unqualified products based on the processing or detection signals recorded and fed back by the previous multiple stations, and releases the clamp in the qualified product area and the unqualified product area respectively to realize the unloading operation. After the unloading is completed, the base rotating disk 22 continues to rotate to the next station, at which time there is no valve product on it.

[0105] The twelfth station 112 is a cleaning station, which uses a cylinder to drive the blowing head and the wire brush on the head to blow and clean the inside of the chuck clamp holding the valve mouth, so as to quickly clean the debris. After the cleaning is completed, the base rotating disk 22 continues to rotate to the first station 11.

[0106] See Figure 4 As shown, the first station 11 includes a loader 1101 arranged on the outside of the base 2; the first station 11 also includes a first station bottom cylinder 1102 arranged on the base 2; a first station feeding cylinder 1103 is arranged on the top of the first station bottom cylinder 1102; a first station clamping cylinder 1104 is arranged on the top of the first station feeding cylinder 1103; a first station clamping cylinder 1104 is arranged on the front of the first station clamping cylinder 1104; a first station clamping jaw 1106 is arranged on the front of the first station clamping jaw rotating device 1105; the base rotating device 1105 of the first station 11 A clamp 1107 is arranged on the turntable 22 area, and the lower part of the clamp 1107 is locked by the clamp gear 1108; a first station locking cylinder 1109 is arranged on the base fixing plate 23 area of ​​the first station 11; a first station locking motor 1110 is arranged on the first station locking cylinder 1109; a first station locking gear 1111 is arranged on the lower part of the first station locking motor 1110, and the first station locking gear 1111 is detachably meshed with the clamp gear 1108; the first station 11 also includes a first station pressing cylinder 1112 arranged on the upper part.

[0107] The loader 1101 transports the valve with its head facing downward to a position close to the first station 11. At this time, the first station clamping cylinder 1104 extends forward under the drive of the first station feeding cylinder 1103, and the first station clamping cylinder 1106 is used to clamp the valve on the loader 1101. Then the first station feeding cylinder 1103 retreats, and the first station bottom cylinder 1102 drives the internal gear to rotate 180 degrees, so that the first station feeding cylinder 1103 rotates 180 degrees to the inside, and the first station clamping rotating device 1105 rotates 180 degrees, so that the head of the valve is facing upward. The first station feeding cylinder 1103 extends forward, so that the bottom of the valve is directly above the fixture 1107, and the head of the first station pressing cylinder 1112 is guided downward to press the valve into the fixture 1107. The first station locking cylinder 1109 extends forward, so that the first station locking gear 1111 and the fixture gear 1108 are meshed, and then the first station locking motor 1110 is started, driving the fixture 1107 to lock the valve. In addition, the first station locking motor 1110 has a torque detection function, and the locking state is determined by the torque. After locking, the first station locking motor 1110 stops rotating, and the first station locking cylinder 1109 returns to its original position. At this time, the loading is completed, and the base rotating disk 22 rotates one station to bring the loaded valve to the second station 12.

[0108] See Figure 5 As shown, the second station 12 includes a second station support column 121 arranged on the base 2; a second station pressing cylinder 122 is arranged on the upper part of the second station support column 121; a second station detection slide 123 which can slide along the second station support column 121 is arranged at the lower part of the second station pressing cylinder 122; the second station detection slide 123 is connected to the outside with a second station detection rod 124; a second station detection head 125 is arranged at the lower part of the second station detection rod 124; a second station detection cylinder 126 is also arranged on the second station support column 121; a second station detection claw 127 is arranged on the second station detection cylinder 126; a clamp 1107 is arranged on the base rotating disk 22 directly below the second station detection head 125, and the lower part of the clamp 1107 is locked by a clamp gear 1108.

[0109] After receiving the valve mouth rotated by the first station 11, the second station 12 performs detection at the second station 12. The second station 12 mainly performs two steps of detection. First, the second station pressing cylinder 122 is started downward to press the second station detection slide 123 downward, thereby driving the second station detection rod 124 to move downward, and then the second station detection head 125 moves downward. When it moves to contact the upper part of the valve mouth, it stops moving. The height of the valve mouth at this time can be measured to determine whether there are products of other models and other lengths mixed in. Secondly, the second station detection cylinder 126 set near the lower part of the second station support column 121 extends, driving the second station detection claw 127 to extend forward, and judging whether it can be inserted into the empty knife position at the bottom of the valve mouth product to judge whether the product feeding state is clamped in place, and whether the bottom of the valve mouth is processed in place before feeding. That is, if the second station detection claw 127 can be smoothly inserted into the bottom of the valve, it means that the valve loading position is accurate and the product is processed before loading. Otherwise, it means that either the product loading position is inaccurate or the bottom of the product is not processed before loading. If the detection result of any of the two-step detection steps is unqualified, the valve at the second station 12 is recorded as unqualified, and the third to tenth stations thereafter do not perform corresponding processing, and when it rotates to the eleventh station 111, it is distinguished for unloading, and the valve is assigned to the unqualified product unloading area 11105 of the eleventh station for unloading. After the second station 12 is detected, the base rotating disk 22 rotates one station to bring the valve to the third station 13.

[0110] See Figure 6 As shown, the third station 13 includes a third station support column 131 arranged on the base 2; a third station slide rail 132 is arranged on the third station support column 131; a third station pressing motor 133 is arranged on the third station slide rail 132; the third station pressing motor 133 drives the third station slide 134 to slide up and down along the third station slide rail 132; a third station processing motor 135 is arranged on the third station slide 134; a third station processing head 136 is arranged at the lower part of the third station processing motor 135; a third station clamp 137 is arranged at the lower part of the third station processing head 136; a clamp 1107 is arranged on the base rotating disk 22 just below the third station clamp 137, and the lower part of the clamp 1107 is locked by a clamp gear 1108.

[0111] The third station 13 is the valve bottom threading station. The third station downward pressure motor 133 drives the third station slide 134 to slide downward on the third station slide rail 132. When the third station clamp 137 reaches the upper part of the valve, the clamp clamps the valve to guide it, and guides the third station processing head 136, i.e., the 12V1 die, into the bottom of the valve. After reaching the threading position, the third station clamp 137 opens, and the die starts to rotate for threading. During the threading process, the third station processing motor 135 cooperates with the torque detection function. If the torque detection is too large during the threading process, it means that the die of the third station processing head 136 is too worn or the valve is too loose. The size of the valve is too large. If the torque detected by the third station processing motor 135 is too small, it means that the size of the valve workpiece itself is insufficient, and when the torque is within the appropriate range, it means that the product and its processing process are qualified. After the threading is completed, the third station processing motor 135 stops, and records whether the valve product of the third station 13 is a qualified product based on the torque situation. Similarly, if it is recorded as an unqualified product, no subsequent stations will carry out processing, and the unqualified product unloading area 11105 of the eleventh station will be unloaded. Otherwise, if it is a qualified product, the subsequent processing will continue. After the processing of the third station 13 is completed, the base rotating disk 22 rotates one station to bring the valve to the fourth station 14.

[0112] See Figure 7 As shown, the fourth station 14 includes a fourth station support column 141 arranged on the base 2; a fourth station slide rail 142 is arranged on the fourth station support column 141; a fourth station pressing motor 143 is arranged on the fourth station slide rail 142; the fourth station pressing motor 143 drives the fourth station slide 144 to slide up and down along the fourth station slide rail 142; a fourth station processing motor 145 is arranged on the fourth station slide 144; a fourth station processing head 146 is arranged at the lower part of the fourth station processing motor 145; a fourth station guide head 147 is arranged at the lower part of the fourth station processing head 146; a clamp 1107 is arranged on the base rotating disk 22 directly below the fourth station guide head 147, and the lower part of the clamp 1107 is locked by the clamp gear 1108.

[0113] The fourth station 14 is a station that uses a fourth station processing head 146 to cooperate with a fourth station guide head 147 to directly process the cavity on the upper part of the valve mouth, that is, the fourth station processing head 146 uses Fig.19The combined tooling shown uses a 3.9mm drill bit and a peripheral rotating turning tool to perform synchronous downward processing, which not only realizes the expansion function of the upper cavity of the valve mouth, but also pre-processes the 8V1 wire processing area that needs to be processed in the subsequent valve mouth, achieving the effect of saving the subsequent 8V1 die. The 3.9mm drill bit processing of the cavity on the upper part of the valve mouth forms an internal cavity step inside the valve mouth due to the expansion of the cavity, which provides space for the downward filling and deflation of the valve core after installation. The outer periphery of the drill bit is turned by the convex turning tool formed by the arc, achieving the effect of performing two processing in one step. Similarly, the fourth station processing motor 145 is also equipped with a torque detection function. If the torque is too large or too small, it will also cause the machining center to record it as a defective product, and the subsequent station will not process it, and the defective product unloading area 11105 of the eleventh station will be unloaded. Otherwise, it is a qualified product and will continue to be processed. After the fourth station 14 is processed, the base rotating disk 22 rotates one station to bring the valve mouth to the fifth station 15.

[0114] like Figure 8 As shown, the fifth station 15 includes a fifth station support column 151 arranged on the base 2; a fifth station slide rail 152 is arranged on the fifth station support column 151; a fifth station pressing motor 153 is arranged on the fifth station slide rail 152; the fifth station pressing motor 153 drives the fifth station slide 154 to slide up and down along the fifth station slide rail 152; a fifth station processing motor 155 is arranged on the fifth station slide 154; a fifth station processing head 156 is arranged at the lower part of the fifth station processing motor 155; a fifth station guide head 157 is arranged at the lower part of the fifth station processing head 156; a clamp 1107 is arranged on the base rotating disk 22 directly below the fifth station guide head 157, and the lower part of the clamp 1107 is locked by the clamp gear 1108.

[0115] The fifth station 15 uses a larger diameter drill bit of 4.7mm to further expand the inner cavity of the valve head after the cavity expansion processing of the fourth station 14, that is, the fifth station downward pressure motor 153 drives the fifth station slide 154 to slide downward along the fifth station slide rail 152, and at the same time starts the fifth station processing motor 155 to drive the fifth station processing head 156 to process, wherein the fifth station processing head 156 uses a 4.7mm drill bit, which further expands the upper cavity of the valve on the basis of the 3.9mm drill bit of the fourth station 14, and performs the 5V1 threading operation for the 5V1 thread hole in the upper inner cavity of the valve. Pre-processing is also carried out to save the threading tools for the subsequent 5V1 thread, so that the size reaches the critical size of the 5V1 threading. Similarly, the fifth station guide head 157 is used for auxiliary guidance during processing. Similarly, the fifth station processing motor 155 is also equipped with a torque detection function. If the torque is too large or too small, the machining center will record it as a defective product, and the subsequent stations will not process it. The defective product unloading area 11105 at the eleventh station will be unloaded. Otherwise, if it is a qualified product, the subsequent processing will continue. After the fifth station 15 is processed, the base rotating disk 22 rotates one station to bring the valve mouth to the sixth station 16.

[0116] like Fig. 9 As shown, the sixth station 16 includes a sixth station support column 161 arranged on the base 2; a sixth station slide rail 162 is arranged on the sixth station support column 161; a sixth station pressing motor 163 is arranged on the sixth station slide rail 162; the sixth station pressing motor 163 drives the sixth station slide 164 to slide up and down along the sixth station slide rail 162; a sixth station processing motor 165 is arranged on the sixth station slide 164; a sixth station processing head 166 is arranged at the lower part of the sixth station processing motor 165; a sixth station guide head 167 is arranged at the lower part of the sixth station processing head 166; a clamp 1107 is arranged on the base rotating disk 22 directly below the sixth station guide head 167, and the lower part of the clamp 1107 is locked by the clamp gear 1108.

[0117] The general structure of the sixth station 16 is similar to that of the fifth station 15. The sixth station pressing motor 163 is also used to drive the sixth station slide 164 to move downward. At the same time, the sixth station processing motor 165 on the sixth station slide 164 drives the sixth station processing head 166 to process the valve. Fig. 20The combined tool shown performs synchronous chamfering and sizing of the inner and outer sides of the valve head. The sizing is to ensure the consistency of the height of the valve after processing, while the inner and outer chamfers, especially the inner chamfer, use a function similar to that of an inner hole cutter, and cooperate with a turning tool formed by two protrusions on the outer side to chamfer and turn the outer side, achieving the effect of realizing two processing functions in one processing step. After the preliminary pre-processing of the 5V1 wire at the fifth station 15, more precise size pre-processing is performed for the subsequent 5V1 internal wire processing at the eighth station 18, and pre-processing is also performed for the fine reaming of the ninth station 19, so as to save the 5V1 threading tool at the eighth station 18 and the fine reamer at the ninth station 19. Similarly, the sixth station processing motor 165 is also equipped with a torque detection function. If the torque is too large or too small, the machining center will record it as a defective product, and the subsequent stations will not process it, and it will be unloaded in the defective product unloading area 11105 at the eleventh station. Otherwise, if it is a qualified product, it will continue to be processed. After the sixth station 16 is processed, the base rotating disk 22 rotates one station and brings the valve nozzle to the seventh station 17.

[0118] like Fig.10 As shown, the seventh station 17 includes a seventh station support column 171 arranged on the base 2; a seventh station slide rail 172 is arranged on the seventh station support column 171; a seventh station pressing motor 173 is arranged on the seventh station slide rail 172; the seventh station pressing motor 173 drives the seventh station slide 174 to slide up and down along the seventh station slide rail 172; a seventh station processing motor 175 is arranged on the seventh station slide 174; a seventh station processing head 176 is arranged at the lower part of the seventh station processing motor 175; a seventh station guide head 177 is arranged at the lower part of the seventh station processing head 176; a clamp 1107 is arranged on the base rotating disk 22 directly below the seventh station guide head 177, and the lower part of the clamp 1107 is locked by the clamp gear 1108.

[0119] The seventh station 17 is a threading station, which threads the outer thread on the upper part of the valve. The seventh station pressing motor 173 drives the seventh station slide 174 to move downward, and at the same time, the seventh station processing motor 175 starts to drive the seventh station processing head 176 to thread the outer side of the valve head. The threading die is 8V1 thread die. Similarly, the seventh station processing motor 175 is also equipped with a torque detection function. If the torque is too large or too small, the machining center will record it as a defective product, and the subsequent stations will not process it, and the defective product unloading area 11105 of the eleventh station will be unloaded. Otherwise, it will be a qualified product and will continue to be processed. After the seventh station 17 is processed, the base rotating disk 22 rotates one station to bring the valve to the eighth station 18.

[0120] like Fig.11As shown, the eighth station 18 includes an eighth station support column 181 arranged on the base 2; an eighth station slide rail 182 is arranged on the eighth station support column 181; an eighth station pressing motor 183 is arranged on the eighth station slide rail 182; the eighth station pressing motor 183 drives the eighth station slide 184 to slide up and down along the eighth station slide rail 182; an eighth station processing motor 185 is arranged on the eighth station slide 184; an eighth station processing head 186 is arranged at the lower part of the eighth station processing motor 185; an eighth station guide head 187 is arranged at the lower part of the eighth station processing head 186; a clamp 1107 is arranged on the base rotating disk 22 directly below the eighth station guide head 187, and the lower part of the clamp 1107 is locked by the clamp gear 1108.

[0121] The eighth station 18 is a station for threading the cavity inside the valve head. The eighth station's downward pressure motor 183 drives the eighth station slide 184 to move downward. At the same time, the eighth station's processing motor 185 is started to drive the eighth station's processing head 186, i.e., the 5V1 die, to perform tapping operations, and the eighth station's guide head 187 plays a guiding role. The inner tapping operation of the eighth station 18 should be set at the rear end of the outer tapping of the seventh station 17. This is because if the inner 5V1 tapping operation is performed first, the subsequent 8V1 outer tapping will have a certain squeezing effect on the valve, causing the inner 5V1 thread to close, i.e., the aperture to become smaller, so that the valve core cannot pass through when the valve is used. Similarly, the eighth station processing motor 185 is also equipped with a torque detection function. If the torque is too large or too small, the machining center will record it as a defective product, and the subsequent stations will not process it, and it will be unloaded in the defective product unloading area 11105 at the eleventh station. Otherwise, if it is a qualified product, it will continue to be processed. After the eighth station 18 is processed, the base rotating disk 22 rotates one station and brings the valve nozzle to the ninth station 19.

[0122] like Fig.12 As shown, the ninth station 19 includes a ninth station support column 191 arranged on the base 2; a ninth station slide rail 192 is arranged on the ninth station support column 191; a ninth station pressing motor 193 is arranged on the ninth station slide rail 192; the ninth station pressing motor 193 drives the ninth station slide 194 to slide up and down along the ninth station slide rail 192; a ninth station processing motor 195 is arranged on the ninth station slide 194; a ninth station processing head 196 is arranged at the lower part of the ninth station processing motor 195; a ninth station guide head 197 is arranged at the lower part of the ninth station processing head 196; a clamp 1107 is arranged on the base rotating disk 22 directly below the ninth station guide head 197, and the lower part of the clamp 1107 is locked by the clamp gear 1108.

[0123] The ninth station 19 is a fine milling operation station after the 5V1 internal thread tapping of the eighth station 18. The ninth station pressing motor 193 drives the ninth station slide 194 to move downward, and at the same time, the ninth station processing motor 195 drives the ninth station processing head 196 to process. The ninth station processing head 196 is a fine milling cutter, which performs fine milling on the inside of the valve. In addition to achieving the required milling angle, it can also remove the burrs after the 5V1 thread processing of the eighth station 18, which is convenient for the entry of the valve core. Similarly, the ninth station processing motor 195 is also equipped with a torque detection function. If the torque is too large or too small, it will also cause the machining center to record it as a defective product, and the subsequent stations will not process it, and the defective product unloading area 11105 of the eleventh station will be unloaded. Otherwise, it will be a qualified product and will continue to be processed. After the ninth station 19 is processed, the base rotating disk 22 rotates one station to bring the valve to the tenth station 110.

[0124] like Fig.13 As shown, the tenth station 110 includes a tenth station support column 11001 arranged on the base 2; a tenth station slide rail 11002 is arranged on the tenth station support column 11001; a tenth station press-down motor 11003 is arranged on the tenth station slide rail 11002; the tenth station press-down motor 11003 drives the tenth station slide 11004 to slide up and down along the tenth station slide rail 11002; a tenth station combination measuring tool 11005 is arranged on the tenth station slide 11004; the tenth station 110 also includes a tenth station blowing device 11006; a clamp 1107 is arranged on the base rotating disk 22 directly below the tenth station combination measuring tool 11005, and the lower part of the clamp 1107 is locked by a clamp gear 1108.

[0125] The tenth station 110 is a purging and testing station, using Fig.21The combined measuring tool shown is combined with the air blowing device for purging and testing. The combined measuring tool 11005 of the tenth station moves to the upper part of the valve, presses down on the product mouth, and uses the bell mouth at the bottom of the combined measuring tool to seal the upper part of the valve. Compressed air is introduced from the right channel for blowing to clean the debris in the cavity caused by all previous processes to avoid detection errors. At the same time, the side air blowing device 11007 can be used for purging, and then the combined measuring tool is used for qualified product detection, that is, the vertical rod with a fixed size in the center of the combined measuring tool is inserted into the upper cavity of the valve to detect whether the 3.9mm drill processing of the fourth station 14 is qualified, mainly to detect whether the depth of the 3.9mm drill processing is qualified, and it can further determine whether the 3.9mm drill is worn and whether the fine milling operation of the ninth station 19 is in place. Similarly, the tenth station 110 is also provided with a recording function for whether the product is qualified. If the inspection fails, the machining center will record it as a defective product and unload it in the defective product unloading area 11105 of the eleventh station. Otherwise, if it is a qualified product, it will be unloaded in the qualified product unloading area 11106 of the eleventh station. After the inspection of the tenth station 110 is completed, the base rotating disk 22 rotates one station and brings the valve nozzle to the eleventh station 111.

[0126] like Fig.14 As shown, the eleventh station 111 includes an eleventh station support column 11101 arranged on the base 2; an eleventh station material taking cylinder 11102 is arranged on the eleventh station support column 11101; an eleventh station clamping claw 11103 is arranged on the upper part of the eleventh station material taking cylinder 11102; an eleventh station blocking cylinder 11104 is arranged on the eleventh station support column 11101 above the eleventh station clamping claw 11103; an eleventh station unqualified product unloading area 11105 is arranged on the base 2 in front of the eleventh station blocking cylinder 11104; and the eleventh station blocking cylinder 11104 is arranged on the side. There is an eleventh station qualified product unloading area 11106; a clamp 1107 is provided on the base rotating disk 22 area of ​​the eleventh station 111, and the lower part of the clamp 1107 is locked by a clamp gear 1108; an eleventh station locking cylinder 11107 is provided on the base fixed disk 23 area of ​​the eleventh station 111; an eleventh station locking motor 11108 is provided on the eleventh station locking cylinder 11107; an eleventh station locking gear 11109 is provided on the lower part of the eleventh station locking motor 11108, and the eleventh station locking gear 11109 is detachably meshed with the clamp gear 1108.

[0127] The eleventh station 111 is distinguished from the unloading station. When the fixture 1107 brings the processed valve nozzle to the eleventh station 111, the eleventh station clamp 11103 moves to the top of the fixture 1107, the eleventh station clamp 11103 clamps the valve nozzle, and then the eleventh station locking cylinder 11107 drives the eleventh station locking motor 11108 to extend forward, so that the eleventh station locking gear 11109 and the fixture gear 1108 are engaged, driving the fixture gear 1108 to rotate, so that the fixture 1107 releases the valve nozzle, and then the eleventh station material taking cylinder 11102 is lifted upward to lift the eleventh station clamp 11103, and then the eleventh station The eleventh station clamp 11103 rotates, and according to the signals of whether the product is qualified recorded at each station at the front end, when it is found that the moving product is unqualified, the eleventh station blocking cylinder 11104 extends to block the valve from further movement, so that it only rotates 90 degrees and stops above the unqualified product unloading area 11105 of the eleventh station, and then the eleventh station clamp 11103 releases the valve to complete the unqualified product unloading. If the product is qualified, the eleventh station clamp 11103 rotates 180 degrees to the eleventh station qualified product unloading area 11106, and then the eleventh station clamp 11103 releases the valve to complete the qualified product unloading. After the unloading of the eleventh station 111 is completed, the base rotating disk 22 rotates one station to bring the valve to the twelfth station 112.

[0128] like Fig.15 As shown, the twelfth station 112 includes a twelfth station support column 11201 disposed on the base 2; the twelfth station support column 11201 is provided with a twelfth station slide rail 11202; the twelfth station slide rail 11202 is provided with a twelfth station downward pressure cylinder 11203; the twelfth station downward pressure cylinder 11203 drives the twelfth station slide 11204 to slide up and down along the twelfth station slide rail 11202; the twelfth station slide A twelfth-station air blowing device 11205 is provided on 11204; a twelfth-station air blowing pipe 11206 is provided at the lower part of the twelfth-station air blowing device 11205; a twelfth-station brush 11207 is provided at the lower part of the twelfth-station air blowing pipe 11206; a clamp 1107 is provided on the base rotating disk 22 just below the twelfth-station brush 11207, and the lower part of the clamp 1107 is locked by a clamp gear 1108.

[0129] The twelfth station 112 is the last cleaning station in the whole process. The twelfth station downward pressure cylinder 11203 drives the twelfth station slide 11204 to move downward, and then drives the twelfth station blowing device 11205 and the twelfth station blowing pipe 11206 and the twelfth station brush 11207 at the lower part to approach the fixture 1107, and blows and rotates the brush to clean the debris generated by all stations before the fixture 1107. After the cleaning is completed, the twelfth station downward pressure cylinder 11203 moves upward to complete the processing of all stations. After the cleaning of the twelfth station 112 is completed, the base rotating disk 22 rotates one station to bring the fixture 1107 back to the first station 11.

[0130] The multi-station machining center for valves disclosed in the present invention can process 10-11 valves per minute. All machining stations that need to rotate are equipped with torque detection devices. If the torque is found to be too large or too small, it will be recorded as a defective product, and no processing will be performed at the subsequent stations until the defective product unloading area 11105 of the eleventh station is unloaded. In addition, the downward pressure motors of all stations use dual servo motors, that is, when processing is required, they first quickly reach the critical processing point, then process at a suitable slow speed, and return to the processing critical point after the processing is completed, and then quickly move upward, thereby improving the processing efficiency. In addition, the machining center can process valves of different models and categories through simple adjustments, and can be applied to valves with hot forging extensions of more than 45 mm, and only the bottom clamp of the fixture 1107 needs to be replaced.

[0131] Working principle: The loader 1101 transports the valve with the bottom facing upward to the first station 11 successively. The first station clamping jaw cylinder 1104 clamps the valve and rotates it to the inside of the processing station. The valve is rotated to the head facing upward by the first station clamping jaw rotating device 1105. The bottom of the valve is pressed into the fixture 1107 by the first station pressing cylinder 1112. Then, the first station locking cylinder 1109 drives the fixture gear 1108 to lock the valve in the fixture 1107. The base rotating cylinder 21 drives the base rotating disk 22 to rotate one station, and the fixture 1107 with the valve is sent to the second station 12. At the same time, the twelfth station 112 that has been processed before also returns to the first station 11 as the base rotating disk 22 rotates. The second station 12 mainly performs two steps of detection, namely, detecting the height of the valve mouth by the downward movement of the second station detection head 125, and detecting the diameter of the lower part of the valve mouth by the second station detection claw 127. The above two detection steps are used to determine whether the valve mouth product to be processed is qualified and record it. While the second station 12 performs a two-step inspection on the valve nozzle, the first station 11 continues to repeat the loading operation. When the second loading of the first station 11 is completed and the two-step inspection of the second station 12 is completed, the base rotating disk 22 rotates one station again. At this time, the valve nozzle product entering the third station 13, if it is recorded as a defective product in the second station 12, the third station 13 and the subsequent stations will not perform processing. If the second station 12 is judged to be a qualified product, the third station 13 will perform threading processing of the bottom 12V1 thread under the drive of the third station processing motor. At the same time, the second station 12 inspects the second valve nozzle that has just entered the station, and the first station 11 continues to load the third valve nozzle. When the first to third stations are processed or inspected, the base rotating disk 22 rotates Turn one station, the fourth station processing motor 145 of the fourth station 14 performs 3.9mm drill processing on the upper cavity of the valve, and the first to third stations also continue to repeat processing or inspection. After the four stations have completed processing or inspection, the base rotating disk 22 rotates one station, and the fifth station 15 uses the fifth station processing motor 155 to perform 4.7mm drill processing in the upper cavity of the valve. Similarly, the first to fourth stations are also repeating the above processing or inspection actions. After the first to fifth stations are processed, the base rotating disk 22 rotates one station, and the sixth station 16 chamfers and sizes the inside and outside of the valve head. At the same time, the first to fifth stations also repeat processing or inspection. After the first to sixth stations are processed or inspected, the base rotating disk 22 rotates one station.Similarly, the seventh station 17 performs 8V1 die threading on the outside of the head, the eighth station 18 performs 5V1 die threading on the inside of the head, the ninth station 19 performs fine milling on the inside of the 5V1 die after processing at the eighth station 18, the tenth station 110 performs measurement and air blowing of the combined measuring tool, the eleventh station 111 performs material separation, and the twelfth station performs purging and cleaning. When each station is operating, the stations in front of it also perform corresponding operations. After all stations have completed the operation, the base rotating disk 22 will rotate to the next station. In this way, the valve nozzle is continuously loaded from the first station 11, and after a series of processing, it is continuously unloaded from the eleventh station 111, realizing continuous processing and testing of the valve nozzle.
