Description

Technical Field

[0001] This invention relates to the field of hardware pipe fitting processing technology, specifically to an automatic sleeve method and an automatic assembly and pressing equipment. Background Technology

[0002] In some industrial sectors, it is necessary to connect metal pipe fittings to one end of long pipes, such as sonic logging pipes. This requires connecting a sleeve with a sealing ring to one end of the main pipe. Crimping is a common connection method, where the sleeve is fitted onto one end of the main pipe, and then the two are joined together using a crimping machine. Currently, the production method involves manually fitting the sleeve onto the main pipe. Specifically, the sleeve is manually moved to the sleeve loading rack on one side of the crimping machine and pushed into the crimping channel. Similarly, the main pipe is manually moved to the main pipe loading rack on the other side of the crimping machine and pushed into the crimping channel to be fitted onto one end of the sleeve. Finally, the crimping machine is started to press the sleeve and the end of the main pipe together. Both loading and unloading require manual operation, resulting in high labor intensity, high labor costs, and low production efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the problems of high labor intensity, high labor costs, and low production efficiency caused by the manual loading and unloading of existing hardware sleeves and fittings, and to provide an automated sleeve assembly method that realizes the automated assembly of sleeves and fittings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic assembly pressing method involves a pressing machine for pressing sleeves and fittings, a material guide fixture disposed on the front side of the pressing channel of the pressing machine, a sleeve feeding mechanism, and a fitting feeding mechanism. The material guide fixture includes a material guide positioning component composed of several enclosing parts, and a material guide actuator for driving the material guide positioning components to open and close. Each material guide positioning component has a first guide positioning part and a second guide positioning part arranged axially on its inner side. When the material guide positioning components are enclosed, each first guide positioning part forms a first guide channel adapted to the sleeve, and each second guide positioning part forms a second guide channel adapted to the fitting. The first guide channel and the second guide channel are coaxial and connected; the method includes: a sleeve feeding mechanism pushes the sleeve into the first guide channel to a first preset position; a fitting feeding mechanism pushes the fitting sequentially from the pressing channel into the second guide channel, further pushes the fitting from the second guide channel into a second preset position, and pre-fits the sleeve; a guide driver drives the guide positioning component to open the guide fixture; a sleeve transfer machine further fits the pre-fitted sleeve into the fitting and extends it into the pressing channel; a pressing machine is started to press the sleeve and fitting together; the sleeve feeding mechanism withdraws the sleeve, and the fitting feeding mechanism pulls the pressed workpiece out of the pressing channel.

[0006] Compared with the prior art, the automatic sleeve method of the present invention guides and positions the sleeve from one side into the first guide channel of the guide fixture and the fitting from the other side into the second guide channel of the guide fixture. After guiding and positioning the fitting and the sleeve at opposite ends, the fitting and the fitting are sleeved together. The sleeve is then pressed onto the end of the fitting by a pressing machine, thereby realizing the automated assembly of the hardware fitting and the sleeve, saving labor costs and improving production efficiency.

[0007] Furthermore, the sleeve feeding mechanism includes a fitting fixture, a translation device, and a pneumatic drive device. The fitting fixture is mounted on the translation device via the pneumatic drive device. The sleeve is pushed into the first guide channel to the first preset position by the fitting fixture driven by the pneumatic drive device. The sleeve in the pre-fitted state is further fitted into the pipe fitting by the translation device and extends into the pressing channel. With this arrangement, the sleeve conveyed by the sleeve feeding mechanism is pre-positioned and then further fitted with the pipe fitting, which better enables the successful docking of the sleeve and the pipe fitting, resulting in high assembly reliability.

[0008] Furthermore, the sleeve is fed by a vibratory feeder and the sleeve connection end is adjusted to face upwards. The pneumatic drive device is connected to the translation device through a flipping device. The flipping device drives the sleeve fitting fixture to flip between the vertical position of receiving the sleeve and the horizontal position of pushing the sleeve. The sleeve at the output end of the vibratory feeder is transferred to the sleeve fitting fixture through a sleeve transfer device. The sleeve transfer device includes a first clamp, a translation drive assembly that drives the first clamp to move horizontally, and a first vertical drive that drives the first clamp to move vertically. With this configuration, the sleeve transfer device is simple to set up and can transfer the sleeve from the sleeve feeding mechanism to the sleeve feeding mechanism in both horizontal and vertical directions.

[0009] Furthermore, the translation device is driven by a servo drive device, which receives feedback of the reaction force of the fitting fixture. When the reaction force exceeds a preset threshold, the servo drive device stops working. With this setting, the translation device is driven by a servo drive device, which can realize the precise positioning and transportation of the sleeve in the first guide channel, and ensure the reliability of the assembly of the sleeve and the fitting.

[0010] Furthermore, a feeding and unloading rack is configured on the rear side of the pressing channel. The rear pusher assembly pushes the pipe fittings to be processed on the feeding and unloading rack forward into the pipe feeding mechanism and to the third preset position. The pipe feeding mechanism pushes the pipe fittings to be processed at the third preset position forward to the second preset position and pulls the pressed workpieces in the pressing channel backward to the third preset position. The third preset position sensor is used to detect whether the pipe fitting has reached the third preset position and provide feedback to the rear pusher assembly. With this configuration, by setting the third preset position sensor, the pipe feeding mechanism can be better provided with the opportunity to receive the pipe fittings transferred by the rear pusher assembly, which facilitates the transfer of the pipe fittings towards the pressing machine.

[0011] Another object of the present invention is to provide an automatic assembly pressing device, including a pressing machine, a material guiding fixture, a sleeve feeding mechanism, and a fitting feeding mechanism; the pressing machine has a pressing channel extending through both ends for pressing the sleeve to the end of the fitting; the material guiding fixture is disposed on the front side of the pressing channel and includes a material guiding positioning component composed of several enclosing parts, and a material guiding driver for driving the material guiding positioning components to open and close; each material guiding positioning component has a first guiding positioning part and a second guiding positioning part arranged axially on its inner side; when each material guiding positioning component is in the enclosed state, each first guiding positioning part encloses to form a first guiding channel adapted to the sleeve. Each second guide positioning part surrounds and forms a second guide channel adapted to the pipe fitting. The first guide channel and the second guide channel are coaxial and connected. The sleeve feeding mechanism is used to push the sleeve into the first guide channel to the first preset position. The pipe fitting feeding mechanism is used to push the pipe fitting from the pressing channel and the second guide channel into the second guide channel to the second preset position and the sleeve pre-fitting, and to pull the pressed workpiece out of the pressing channel. The guide driver drives the guide positioning part to open the guide fixture. The sleeve transfer machine further fits the pre-fitted sleeve into the pipe fitting and extends into the pressing channel. The pressing machine presses and connects the sleeve and the pipe fitting.

[0012] Compared with the prior art, the automatic assembly and pressing equipment of the present invention guides and positions the sleeve from one side into the first guide channel of the guide fixture and the fitting from the other side into the second guide channel of the guide fixture. After guiding and positioning the fitting, the fitting and the opposite end of the sleeve are connected. The sleeve is then pressed to the end of the fitting by the pressing machine, realizing the automated assembly of hardware fittings and sleeves, saving labor costs and improving production efficiency.

[0013] Furthermore, the sleeve feeding mechanism includes a fitting fixture, a translation device, and a pneumatic drive device. The fitting fixture is mounted on the translation device via the pneumatic drive device, which is driven by a servo drive device. The pneumatic drive device pushes the fitting fixture into the first guide channel to a first preset position. The translation device then further inserts the pre-fitted sleeve into the fitting and extends it into the pressing channel. The servo drive device receives feedback from the reaction force of the fitting fixture. When the reaction force exceeds a preset threshold, the servo drive device stops working. With this configuration, the translation device is driven by a servo drive device, which enables precise positioning and conveying of the sleeve within the first guide channel, ensuring the reliability of the sleeve and fitting assembly.

[0014] Furthermore, the sleeve is fed by a vibratory feeder and the sleeve connection end is adjusted to face upwards. The pneumatic drive device is connected to the translation device through a flipping device. The flipping device drives the sleeve fitting fixture to flip between the vertical position of receiving the sleeve and the horizontal position of pushing the sleeve. The sleeve at the output end of the vibratory feeder is transferred to the sleeve fitting fixture through a sleeve transfer device. The sleeve transfer device includes a first clamp and a translation drive assembly that drives the first clamp to move horizontally and a first vertical drive that drives the first clamp to move vertically. With this configuration, the sleeve transfer device is simple to set up and can transfer the sleeve from the sleeve feeding mechanism to the sleeve feeding mechanism in both horizontal and vertical directions.

[0015] Furthermore, it further includes: a feeding and unloading rack and a third preset position sensor; the feeding and unloading rack is configured on the rear side of the pressing channel, and its rear end is configured with a rear pusher assembly that pushes the pipe to be processed on the feeding and unloading rack forward into the pipe feeding mechanism and reaches the third preset position; the pipe feeding mechanism pushes the pipe to be processed at the third preset position forward to the second preset position, and pulls the pressed workpiece in the pressing channel backward to the third preset position; the third preset position sensor is used to detect whether the pipe has reached the third preset position and provide feedback to the rear drive; with this configuration, by setting the third preset position sensor, the timing for the pipe feeding mechanism to receive the pipe transferred by the rear pusher assembly can be better provided, which facilitates the transfer of the pipe towards the pressing machine.

[0016] Furthermore, the pipe fitting feeding mechanism includes a front-end feeding mechanism and a pipe fitting clamping feeding mechanism. The front-end feeding mechanism is used to transfer the pipe fitting forward to the pipe fitting clamping feeding mechanism, which then pushes it further to the second preset position and the sleeve pre-fitting, and pulls the pressed workpiece out of the pressing channel. The pipe fitting clamping feeding mechanism includes a longitudinal displacement device and a pneumatically driven pusher and a screw-driven pusher arranged opposite to each other on the longitudinal displacement device. The pneumatically driven pusher and the screw-driven pusher are relatively close to or separate from each other to clamp or release the pipe fitting. With this configuration, after the front-end feeding mechanism transfers the pipe fitting to the pipe fitting clamping feeding mechanism, the pipe fitting clamping feeding mechanism fully clamps the pipe fitting and conveys it to the pressing machine, avoiding displacement of the pipe fitting during the pressing process and ensuring the reliability of the pressing process.

[0029] The technical solution of the present invention is described below with reference to the accompanying drawings:

[0030] Example 1:

[0031] See Figure 1 , Figures 7 to 11 and Figure 12 This embodiment involves a pressing machine 2, a material guiding fixture 1, a sleeve feeding mechanism 4, and a fitting feeding mechanism. The pressing machine 2 is used to press the sleeve 103 and the fitting together. The material guiding fixture 1, the sleeve feeding mechanism 4, and the fitting feeding mechanism are arranged in front of the pressing channel 21 of the pressing machine 2. The material guiding fixture 1 includes a material guiding positioning component 11 composed of several enclosing blocks, and a material guiding driver 12 that drives the material guiding positioning component 11 to open and close. Each material guiding positioning component 11 has a first guiding positioning part and a second guiding positioning part arranged axially on its inner side. When each material guiding positioning component 11 is enclosed, each first guiding positioning part encloses to form a first guiding channel 13 adapted to the sleeve 103, and each second guiding positioning part encloses to form a second guiding channel 14 adapted to the fitting 104. The first guiding channel 13 and the second guiding channel 14 are coaxial and connected. The sleeve method of the present invention is as follows:

[0032] S1. The sleeve feeding mechanism 4 pushes the sleeve 103 into the first guide channel 13 to the first preset position.

[0033] S2. The pipe feeding mechanism pushes the pipe 104 sequentially from the pressing channel 21 and the second guide channel 14 into the second guide channel 14 to the second preset position and pre-fit the sleeve 103.

[0034] S3. The material guide driver 12 drives the material guide positioning component 11 to open the material guide fixture 1.

[0035] S4. The sleeve transfer machine further inserts the pre-fitted sleeve 103 into the fitting 104 and extends it into the pressing channel 21.

[0036] S5. Start the press machine 2 to press and connect the sleeve 103 and the fitting 104.

[0037] S6. The sleeve feeding mechanism 4 exits the sleeve 103, and the fitting feeding mechanism pulls the pressed workpiece out of the pressing channel 21.

[0038] The purpose of the first guide channel 13 and the second guide channel 14 is to facilitate the further fitting of the two ends of the sleeve 103 and the fitting 104 into place after they are guided and positioned together, so as to ensure that the sleeve 103 and the fitting 104 complete the pressing process.

[0039] The automatic sleeve method of the present invention involves center-guiding and positioning the sleeve 103 from one side into the first guide channel 13 of the guide fixture 1, and center-guiding and positioning the fitting 104 from the other side into the second guide channel 14 of the guide fixture 1. Then, the fitting 104 is sleeved with the opposite end of the sleeve 103, and the sleeve 103 is pressed onto the end of the fitting 104 by the working of the pressing machine 2. This realizes the automated assembly of the hardware fitting and the sleeve 103, saving labor costs and improving production efficiency.

[0040] See Figure 11 and Figure 12 In a further embodiment, two material guiding and positioning components 11 are provided, and each material guiding and positioning component 11 is equipped with a material guiding driver 12. The material guiding driver 12 is preferably a push rod. Each material guiding driver 12 realizes the opening and closing of the material guiding and positioning component 11 by driving the corresponding material guiding and positioning component 11.

[0041] See Figure 12In one embodiment, the first guide channel includes a tapered portion 111 and a circular portion 112 from the outside to the inside. The first guide channel surrounds and forms a connected tapered hole and a circular hole. By configuring the tapered portion 111 in this way, the sleeve 103 is easily inserted, and the circular portion 112 achieves radial positioning of the sleeve 103. The second guide channel also includes a tapered portion 111 and a circular portion 112 from the outside to the inside. The second guide channel surrounds and forms a connected tapered hole and a circular hole. By configuring the tapered portion 111 in this way, the kit 104 is easily inserted, and the circular portion 112 achieves radial positioning of the kit 104.

[0042] Figures 7 to 12 In one embodiment, the sleeve feeding mechanism 4 includes a fitting fixture 41, a translation device, and a pneumatic drive device 43. The pneumatic drive device 43 is a pneumatic push rod, and the fitting fixture 41 is mounted on the translation device via the pneumatic drive device 43. The sleeve 103 is pushed into the first guide channel 13 to the first preset position by the fitting fixture 41 driven by the pneumatic drive device 43. The sleeve 103 in the pre-fitted state is further fitted into the fitting 104 by the translation device and extends into the pressing channel 21. With this arrangement, the sleeve 103 conveyed by the sleeve feeding mechanism 4 is pre-positioned and further fitted with the fitting 104, which better enables the successful docking of the sleeve 103 and the fitting 104, resulting in high assembly reliability.

[0043] Figures 7 to 12 In one embodiment, the sleeve 103 is fed by a vibratory feeder and the connecting end of the sleeve 103 is adjusted upwards. The pneumatic drive device 43 is connected to the translation device via a flipping device 42, preferably a motor. The flipping device 42 drives the fitting fixture 41 to flip between a vertical position receiving the sleeve 103 and a horizontal position pushing the sleeve 103. The sleeve 103 at the output end of the vibratory feeder is transferred to the fitting fixture 41 via a sleeve transfer device 5. The sleeve transfer device 5 includes a first clamp 51, a translation drive assembly for driving the first clamp 51 to move horizontally, and a first vertical driver 52 for driving the first clamp 51 to move vertically. A vertical actuator 52 is a push rod, and the first clamping device 51 is disposed at the output end of the first vertical actuator 52. The translation drive assembly includes a translation push rod 53, and a first slide 54 and a first slide rail device 55 that slide out relative to each other. The first vertical actuator 52 is horizontally slidably disposed on the first frame 101 through the first slide 54 and the first slide rail device 55. The translation push rod 53 drives the first slide 54 to transfer the first clamping device 51 between the sleeve feeding mechanism 3 and the sleeve feeding mechanism 4. With this configuration, the sleeve transfer device 5 is simple to set up and can transfer the sleeve 103 of the sleeve feeding mechanism 3 to the sleeve feeding mechanism 4 in both horizontal and vertical directions.

[0044] In one embodiment, the translation device is driven by a servo drive device. The servo drive device receives feedback of the reaction force of the fitting fixture 41. When the reaction force exceeds a preset threshold, the servo drive device stops working. By setting the translation device to be driven by a servo drive device, and the servo drive device stopping working when the reaction force exceeds the preset threshold, it can effectively avoid the deformed or unqualified sleeve 103 being unable to fit with the fitting 104 and continuing to push, which would cause the fitting 104 to suffer hard wear, thus ensuring the reliability of the fitting of the sleeve 103 and the fitting 104.

[0045] It can achieve precise positioning and conveying of the sleeve 103 within the first guide channel 13, ensuring the reliability of the assembly of the sleeve 103 and the fitting.

[0046] See Figures 7 to 9 In a further embodiment, the translation device includes a translation driver 45, a slide 46, and a guide rail mechanism 47. The translation driver 45 is preferably a servo electric cylinder. The flipping device 42, the rotating connecting frame 44, the pneumatic drive device 43, and the fitting fixture 41 are disposed on the slide 46. The slide 46 is mounted through the guide rail mechanism 47. The translation driver 45 is connected to the slide 46 in a transmission manner.

[0047] See Figure 1 , Figure 4 , Figure 5 , Figures 7 to 9 In one embodiment, a feeding and unloading rack is configured on the rear side of the pressing channel 21. The rear pusher assembly 72 pushes the pipe to be processed 104 on the feeding and unloading rack forward into the pipe feeding mechanism and to the third preset position. The pipe feeding mechanism pushes the pipe to be processed at the third preset position forward to the second preset position and pulls the pressed workpiece in the pressing channel 21 backward to the third preset position. The third preset position sensor is used to detect whether the pipe has reached the third preset position and provide feedback to the rear pusher assembly 72. With this configuration, by setting the third preset position sensor, the pipe feeding mechanism can be better provided with the opportunity to receive the pipe 104 transmitted by the rear pusher assembly 72, which facilitates the transmission of the pipe towards the pressing machine 2.

[0048] The specific structural implementation of the automatic assembly and pressing method in this embodiment can be found in the automatic assembly and pressing equipment of Embodiment 2.

[0049] Example 2:

[0050] See Figure 1Figure 11 shows the automatic assembly pressing equipment of the present invention, including a pressing machine 2, a material guiding fixture 1, a sleeve feeding mechanism 4, and a fitting feeding mechanism; the pressing machine 2 has a pressing channel 21 extending through both ends for pressing the sleeve 103 to the end of the fitting 104; the material guiding fixture 1 is disposed on the front side of the pressing channel 21, including a material guiding positioning component 11 composed of several enclosing parts, and a material guiding driver 12 for driving the material guiding positioning component 11 to open and close. Each material guiding positioning component 11 has a first guiding positioning part and a second guiding positioning part arranged axially on its inner side. When each material guiding positioning component 11 is enclosed, each first guiding positioning part encloses to form a first guiding channel 13 with an outer conical hole and an inner circular hole structure that is adapted to the sleeve 103, and each second guiding positioning part encloses to form The second guide channel 14, which is adapted to the pipe fitting, has a tapered hole at the outer end and a circular hole at the inner end. The first guide channel 13 and the second guide channel 14 are coaxial and connected. The sleeve feeding mechanism 4 is used to push the sleeve 103 into the first guide channel 13 to the first preset position. The pipe fitting feeding mechanism is used to push the pipe fitting 104 from the pressing channel 21 and the second guide channel 14 into the second guide channel 14 to the second preset position and pre-fit the sleeve 103, and pull the pressed workpiece out of the pressing channel 21. The guide driver 12 drives the guide positioning component 11 to open the guide fixture 1. The sleeve 103 transfer machine further fits the pre-fitted sleeve 103 into the pipe fitting 104 and extends into the pressing channel 21. The pressing machine 2 presses the sleeve 103 and the pipe fitting 104 together.

[0051] Compared with the prior art, the automatic assembly and pressing equipment of the present invention guides and positions the sleeve 103 from one side into the first guide channel 13 in the guide fixture 1, and guides and positions the fitting 104 from the other side into the second guide channel 14 in the guide fixture 1. Then, the fitting and the opposite end of the sleeve are connected, and the sleeve 103 is pressed to the end of the fitting 104 by the pressing machine 2. This realizes the automated assembly of the hardware fitting and the sleeve 103, saving labor costs and improving production efficiency.

[0052] See Figure 12 In a further embodiment, two material guiding and positioning components 11 are provided, and each material guiding and positioning component 11 is equipped with a material guiding driver 12. The material guiding driver 12 is preferably a push rod. Each material guiding driver 12 realizes the opening and closing of the material guiding and positioning component 11 by driving the corresponding material guiding and positioning component 11.

[0053] See Figures 7 to 9In one embodiment, the sleeve feeding mechanism 4 includes a sleeve fitting fixture 41, a flipping device 42, a translation device, and a pneumatic drive device 43. The flipping device 42 is preferably a motor, and the pneumatic drive device 43 is a pneumatic push rod. The sleeve fitting fixture 41 is connected to the rotating end of the flipping device 42 via the pneumatic drive device 43. The sleeve fitting fixture 41 is located at the output end of the pneumatic drive device 43. The pneumatic drive device 43 is connected to the output end of the flipping device 42 via a rotating connecting frame 44. The flipping device 42 is mounted on the translation device, which drives the sleeve fitting fixture 41 to move relative to the pressing machine 2. The translation device is driven by a servo drive device. The pressure drive device 43 drives the fitting fixture 41 to push into the first guide channel 13 to the first preset position. The translation device is used to further fit the pre-fitted sleeve 103 into the fitting 104 in the press machine 2 and extend it into the fourth preset position of the press channel 21, and to move the fitting fixture 41 to the fifth preset position of receiving the sleeve 103. The servo drive device receives the feedback of the reaction force of the fitting fixture 41. When the reaction force exceeds the preset threshold, the servo drive device stops working. With this setting, the translation device is driven by the servo drive device, which can realize the accurate positioning and transportation of the sleeve 103 in the first guide channel 13, and ensure the assembly reliability of the sleeve 103 and the fitting.

[0054] See Figures 7 to 9 In a further embodiment, the translation device includes a translation driver 45, a slide 46, and a guide rail mechanism 47. The translation driver 45 is preferably a servo electric cylinder. The flipping device 42, the rotating connecting frame 44, the pneumatic drive device 43, and the fitting fixture 41 are disposed on the slide 46. The slide 46 is slidably disposed on the first frame 101 through the guide rail mechanism 47. The translation driver 45 is connected to the slide 46 in a transmission manner.

[0055] See Figures 7 to 9In one embodiment, the device further includes a sleeve feeding mechanism 3, which is a vibratory feeder feeding mechanism. The sleeve 103 is fed by the vibratory feeder, and the connecting end of the sleeve 103 is adjusted to face upwards. The translation device drives the fitting fixture 41 to move in the direction relative to the pressing machine 2. The flipping device 42 drives the fitting fixture 41 to flip between the vertical position receiving the sleeve 103 and the horizontal position pushing the sleeve 103. The sleeve 103 at the output end of the vibratory feeder is transferred to the fitting fixture 41 by the sleeve transfer device 5. The sleeve transfer device 5 includes a first clamp 51 and a translation drive assembly for driving the first clamp 51 to move horizontally and a first vertical drive assembly for driving the first clamp 51 to move vertically. The first vertical driver 52 is a push rod, and the first clamping device 51 is located at the output end of the first vertical driver 52. The translation drive assembly includes a translation push rod 53, and a first slide 54 and a first slide rail device 55 that slide outwards relative to each other. The first vertical driver 52 is horizontally slidably mounted on the first frame 101 through the first slide 54 and the first slide rail device 55. The translation push rod 53 drives the first slide 54 to enable the first clamping device 51 to transfer materials between the sleeve feeding mechanism 3 and the sleeve feeding mechanism 4. With this configuration, the sleeve transfer device 5 is simple to set up and can transfer the sleeve 103 of the sleeve feeding mechanism 3 to the sleeve feeding mechanism 4 in both horizontal and vertical directions.

[0056] See Figure 1 As shown in Figure 6, in one embodiment, the automatic assembly pressing equipment further includes: a feeding and unloading rack and a third preset position sensor; the feeding and unloading rack is configured on the rear side of the pressing channel 21, and its rear end is configured with a rear pusher assembly 72 that pushes the pipe fitting 104 to be processed on the feeding and unloading rack forward into the pipe fitting 104 feeding mechanism and reaches the third preset position; the pipe fitting feeding mechanism pushes the pipe fitting 104 to be processed at the third preset position forward to the second preset position, and pulls the pressed workpiece in the pressing channel 21 backward to the third preset position; the third preset position sensor is used to detect whether the pipe fitting 104 has reached the third preset position and provide feedback to the rear drive; with this configuration, by setting the third preset position sensor, the timing for the pipe fitting feeding mechanism to receive the pipe fitting 104 transmitted by the rear pusher assembly 72 can be better provided, which facilitates the transmission of the pipe fitting 104 towards the pressing machine 2.

[0057] See Figures 1 to 9In one embodiment, the pipe feeding mechanism includes a front-end feeding mechanism 73 and a pipe clamping feeding mechanism (not shown) disposed at the front end of the feeding and unloading rack. The front-end feeding mechanism 73 is used to forwardly transfer the pipe 104 to the pipe clamping feeding mechanism, which then pushes it further to a second preset position and pre-fits the sleeve 103, and pulls the pressed workpiece out of the pressing channel 21. The pipe clamping feeding mechanism includes a longitudinal displacement device and a pneumatically driven pusher and a screw-driven pusher arranged opposite to each other on the longitudinal displacement device. The longitudinal displacement device is used to drive the pipe clamping feeding mechanism to transfer the pipe 104 between the front-end feeding mechanism 73 and the pressing machine 2. When the third preset position sensor detects that the pipe 104 has reached the corresponding position, it triggers the pipe clamping feeding mechanism to clamp the pipe 104 to be processed and to convey the pipe 104 to be processed. The pipe 104 is sent to the pressing machine 2 for processing, and after the pipe 104 is processed, it is transferred to the front feeding mechanism 73 for unloading. The pneumatically driven push clamp and the screw-driven push clamp are relatively close to or separate to clamp or release the pipe 104. Specifically, after the screw-driven push clamp abuts against one side of the pipe 104 to be processed, the pneumatically driven push clamp further cooperates with the screw-driven push clamp on the other side of the pipe 104 to clamp the pipe 104 to be processed. With this setting, after the front feeding mechanism 73 transmits the pipe 104 to the pipe clamping feeding mechanism, the pipe clamping feeding mechanism fully clamps the pipe 104 and conveys it to the pressing machine 2, avoiding displacement of the pipe 104 during the pressing process and ensuring the reliability of the pressing process. The clamping method of using the pneumatically driven push clamp and the screw-driven push clamp can better avoid clamping damage to the pipe 104.

[0058] See Figures 1 to 6 In one embodiment, it further includes a pipe conveying mechanism 6 and a material transfer mechanism; the feeding and unloading rack is disposed on the rear side of the pressing channel 21 and is used to support the feeding and unloading of the pipe 104; the pipe conveying mechanism 6 is used to move the pipe 104 toward the feeding and unloading rack; the material transfer mechanism 8 is used to transfer the pipe 104 at the end of the pipe conveying mechanism 6 to the feeding and unloading rack.

[0059] See Figures 1 to 4 In one embodiment, the machine also includes a first frame 101 and a second frame 102 arranged adjacent to each other. The press 2, the sleeve feeding mechanism 3, the sleeve feeding mechanism 4, the fitting clamping feeding mechanism and the front feeding mechanism 73 are arranged on the first frame 101. The fitting conveying mechanism 6, the feeding and unloading frame, the material transfer mechanism 8 and the rear pushing assembly 72 are arranged on the second frame 102. The sleeve feeding mechanism 4 and the front feeding mechanism 73 are respectively located on both sides of the press 2. The third preset position sensor is arranged on the side of the end of the press 2 through the sensor bracket 105.

[0060] See Figures 1 to 5In one embodiment, the feeding and unloading rack is provided with a plurality of centering guides 71 arranged at intervals for supporting and guiding the pipe fittings. The centering guides 71 are centering guide rollers. The rack also includes a pressing mechanism, which includes a front pressing rack 74 and a rear pressing rack 75 arranged at intervals above the front end and rear end of the feeding and unloading rack, respectively. The front pressing rack 74 and the rear pressing rack 75 each include a centering guide wheel 741 and a second vertical actuator 742 for driving the centering guide wheel 741 to move vertically. The second vertical actuator 742 is preferably a push rod. The pressing mechanism is used to cooperate with the centering guides 71 to guide the pipe fittings horizontally and position them vertically. With this arrangement, the pressing mechanism can better limit the pipe fittings on the feeding and unloading rack by pressing down, preventing the pipe fittings from falling off the feeding and unloading rack during operation.

[0061] See Figures 3 to 6 In one embodiment, several material transfer mechanisms 8 are provided along the length conveying direction of the pipe fitting. Each material transfer mechanism 8 includes a feeding guide frame 81 arranged below the centering guide 71, a material transfer component 82, and a material transfer driver 83 that drives the material transfer component 82 to move vertically. The feeding guide frame 81 is located on one side of the material transfer component 82 along the feeding direction. The feeding guide frame 81 has a feeding guide inclined surface 811 arranged downwards along the feeding direction. The upper side of the material transfer component 82... A first inclined guide surface 821 and a second inclined guide surface 822 are sequentially arranged downwardly along the feeding direction to the unloading direction. The first end of the first inclined guide surface 821 extends to the end of the pipe conveying mechanism 6. A first positioning part 823 is formed between the end of the first inclined guide surface 821 and the first end of the second inclined guide surface 822. The first positioning part 823 is biased towards the center of the centering guide 71 on the side closer to the pipe conveying mechanism 6. The end of the second inclined guide surface 822 extends to the centering guide 71. On the other side, a second positioning part 824 is provided at the end of the second guide slope 822, and the second positioning part 824 corresponds to the unloading guide slope 811; the transfer driver 83 drives the transfer member 82 to rise, and the pipe at the end of the pipe conveying mechanism 6 is transferred to the first guide slope 821 through the first guide slope 821 and the first positioning part 823. At the same time, the pipe located on the centering guide 71 is taken out and slid to the second positioning part 82 on the other side through the second guide slope 822. 4; The transfer driver 83 drives the transfer component 82 to descend, placing the pipe on the first guide slope 821 onto the centering guide 71, and placing the processed pipe on the second guide slope 822 onto the unloading guide slope 811 for unloading; With this configuration, the transfer mechanism 8 can transfer the pipe at the front end of the pipe conveying mechanism to the centering guide 71, and remove the processed pipe from the centering guide 71 for unloading, while simultaneously realizing the position transfer of two pipes, resulting in high working efficiency.

[0062] See Figure 2 and Figure 3 In one embodiment, the system further includes a pipe loading mechanism 91 connected to the pipe conveying mechanism 6. The pipe loading mechanism 91 includes multiple sets of loading conveying components 912 and a loading driver 911 that drives each loading conveying component 912. Each loading conveying component 912 includes a guide wheel 913, a take-up wheel 914, a loading belt 915, and a first support 916. The two ends of the loading belt 915 are respectively connected to the first support 916 and the take-up wheel 914, and the middle portion is wound around the guide wheel 913 located at the beginning of the pipe conveying mechanism 6. The take-up wheel 914 is disposed on the pipe conveying mechanism. Below 6, the feeding belt 915 is connected to one end of the first bracket 916 and is located on the upper side of the guide wheel 913. The feeding belt 915 forms a pipe loading and placement area 917 for loading pipes between the guide wheel 913 and the first bracket 916. The feeding driver 911 drives the winding wheel 914 to wind up the feeding belt 915, thereby lifting the pipes in the pipe loading and placement area 917 upward and transferring them to the first end of the pipe conveying mechanism 6. With this configuration, the pipe loading mechanism 91 has a simple structure, can realize the sequential feeding of pipes, and has a lower manufacturing cost compared to the robotic arm feeding method.

[0063] In a further embodiment, a limit switch (not shown) is provided on the upper side of one end of the first bracket 916 connected to the feeding belt 915. The limit switch is used to be triggered when the feeding belt 915 is wound to the limit, thereby controlling the feeding driver 911 to stop working, so as to avoid the feeding belt 915 being over-wound and causing damage to the first bracket 916.

[0064] See Figure 3 and Figure 5 In one embodiment, a pipe guide frame 66 is further provided on the upper side of the pipe conveying mechanism 6. A pipe conveying channel 67 is formed between the pipe guide frame 66 and the pipe conveying mechanism 6. The spacing of the pipe conveying channel 67 is less than the width of two pipes. A pipe inlet 661 is provided at the outer end of the pipe guide frame 66. With this arrangement, the stacking of materials in the pipe conveying channel 67 is better avoided, and the pipes are conveyed one by one.

[0065] See Figure 2 and Figure 3In one embodiment, the system further includes a pipe unloading mechanism 92 connected to the side of the unloading guide frame 81. The pipe unloading mechanism 92 includes multiple sets of spaced-apart dropping and storage components 921. Each dropping and storage component 921 includes a storage belt 922 and a second support 923. The upper part of the second support 923 is provided with a V-shaped connecting frame. The two ends of the storage belt 922 are respectively connected to the upper two ends of the V-shaped connecting frame and kept in a slack state, so that the storage belt 922 as a whole also maintains a V-shape. Thus, the storage belt 922 forms a pipe unloading and placement area 924 between the two ends. Furthermore, the lower end of the unloading guide slope 811 of the unloading guide frame 81 is located in the unloading and placement area 924, which can better ensure that the pipe unloaded by the unloading guide frame 81 can fall directly into the unloading and placement area 924.

[0066] See Figures 2 to 6 In one embodiment, the pipe conveying mechanism 6 includes a plurality of spaced-apart support members 68, pipe conveying assemblies 62, and a pipe conveying drive mechanism 61 for driving the operation of each pipe conveying assembly 62. The support members 68 have a support portion extending along the pipe conveying direction on their upper side. A feeding guide ramp 681 is provided on the side of the support portion near the feeding / unloading rack. A feeding positioning portion 682 is provided at the end of the feeding guide ramp 681. The pipe conveying assembly 62 includes a conveyor for driving the pipes to move along the support portion. The pipe conveying drive mechanism 61 is preferably... The motor and the conveyor include a conveyor chain 65 and a first sprocket 63 and a second sprocket 64 arranged at intervals. The conveyor chain 65 is respectively wound around the first sprocket 63 and the second sprocket 64. The pipe conveying drive mechanism 61 is connected to the first sprocket 63 through a drive shaft 611. Thus, the pipe conveying drive mechanism 61 drives the first sprocket 63 and the second sprocket 64 to rotate, thereby driving the pipes on the conveyor chain 65 to be conveyed to the feeding and unloading rack side. With this configuration, the pipe conveying mechanism 6 has a simple structure and good positioning effect after the pipes are loaded onto the supporting member 68.

[0067] See Figures 2 to 6In one embodiment, a first sensor (not shown) and a second sensor (not shown) disposed at a distance above the supporting member 68 are also included. The first and second sensors are, for example, photoelectric sensors. The first sensor is used to detect the pipe at the end of the feeding guide ramp 681, and the second sensor is used to detect the pipe at a preset distance from the end of the feeding guide ramp 681. The pipe conveying assembly 62 conveys the pipe towards the end of the feeding guide ramp 681 according to the detection signals of the first and second sensors. For example, when the first and second sensors detect that there is no pipe at the corresponding position, the pipe conveying assembly 62 conveys the pipe towards the end of the feeding guide ramp 681. With this arrangement, by setting the first and second sensors, the continuous supply of pipes by the pipe conveying assembly 62 can be better controlled.

[0068] See Figure 7 and Figure 10 In one embodiment, the front-end driver 732 is preferably a push rod, and the front-end clamp 731 includes two clamping members 733, a clamping push rod 734, and a bidirectional gear transmission structure. The bidirectional gear transmission structure includes a drive gear 735 and two opposing rack transmission members 736. Each clamping member 733 is equipped with one rack transmission member 736, and the bottoms of the two clamping members 733 slide relative to or opposite to each other in the lateral direction via a second slide rail device 737. The two rack transmission members 736 are respectively disposed on both sides of the drive gear 735 and mesh with the outer side of the drive gear 735. The clamping push rod 734... 34 is connected to one of the rack and pinion drive components 736. The two clamping components 733 clamp or release the pipe 104 relative to each other through the forward and reverse drive of the clamping push rod 734. The front clamping device 731 is set on the second slide rail device 737 through the second slide. The front driver 732 is connected to the second slide so that the front clamping device 731 can slide relative to each other in the longitudinal direction, so as to feed the pipe 104 to be processed forward into the press and pull out the processed pipe 104 in the press. With this setting, the front feeding mechanism 73 is simple to set and has a good clamping effect on the movement of the pipe 104.

[0069] See Figure 3 In one embodiment, the rear pusher assembly 72 includes a rear clamp (not shown) and a rear driver 74 that drives the rear clamp to reciprocate along the direction of the press. The rear driver 74 is preferably a screw drive mechanism. With this configuration, the front feeder mechanism 73 and the rear pusher assembly 72 are simple to set up and have a good clamping effect on the movement of the pipe fitting 104.

[0070] See Figures 3 to 5In one embodiment, the centering guide 71 is equipped with a height adjustment driver 711 at its bottom. The centering guide 71 is mounted on the second frame 102 via the height adjustment driver 711. The height adjustment driver 711 is preferably a hand-cranked screw drive mechanism. The height adjustment driver 711 is used to adjust the distance between the centering guide 71 and the pipe guide frame 66, so that the pipe conveying channel 67 can be adapted to pipes 104 with different outer diameters.

[0071] The automatic assembly and pressing equipment of the present invention includes the following working process during the pressing and assembly of the sleeve 103 and the fitting 104:

[0072] The sleeve transfer device 5 takes out the sleeve 103 from the sleeve feeding mechanism 3 and places it vertically downward onto the sleeve feeding mechanism 4, which is placed vertically on the sleeve fitting fixture 41. Then, the flipping device 42 drives the fitting fixture 41 to flip to the horizontal direction. The air pressure driving device 43 drives the fitting fixture 41 to extend into the first guide channel 13 of the guide positioning member 11 in the closed state to make contact and realize the sleeve 103 on the fitting fixture 41 is guided and positioned.

[0073] While the sleeve transfer device 5 feeds the sleeve feeding mechanism 4, the pipe feeding mechanism 91 transports the pipe 103 in the feeding placement area 917 to the pipe conveying mechanism 6. The pipe conveying mechanism 6 then transports the pipe 103 to the centering guide 71. The pipe 104 at the front end of the pipe conveying mechanism is then transferred to the centering guide 71 by the transfer mechanism 8. After the pipe 104 is transferred to the centering guide 71, the rear push assembly 72 transfers the pipe 104 along its length to the front feeding mechanism 73. Under the action of the front feeding mechanism 73, the pipe 104 is transferred to the pipe clamping conveying mechanism. After being fully clamped, the pipe 104 is driven to pass through the pressing processing channel 21 of the press machine 2 and contact the second guide channel 14 of the guide positioning component 11 in the closed state to achieve the guiding and positioning of the pipe 104.

[0074] After the sleeve 103 and the fitting 104 are guided and positioned, the guide driver 12 drives the guide positioning member 11 to open, forming a clearance space for the sleeve 103 to extend further into the press machine. Then, the translation driver 45 drives the sleeve 103 on the fitting fixture 41 to pass through the clearance space and enter the pressing processing channel 21 and fit onto the end of the fitting 104. Finally, the press machine 2 presses and assembles the sleeve 103 and the fitting 104.

[0075] After the pressing and assembly connection is completed, the front feeding mechanism 73 pulls the pipe fitting 104 equipped with the sleeve 103 backward out of the pressing processing channel 2, and the rear pushing component 72 pulls the processed pipe fitting 104 backward until it is separated from the front feeding mechanism 73. Finally, the transfer mechanism 8 transfers the processed pipe fitting 104 on the centering guide 71 to the unloading guide frame 81, and slides it into the pipe fitting unloading placement area 924 through the unloading guide slope 811 of the unloading guide frame 81 to complete the unloading.
