Description

Technical Field

[0001] This invention relates to the technical field of machining equipment, and in particular to a multi-station assembly pressing device. Background Technology

[0002] The process of pressing tubular materials typically involves multiple steps, including feeding, fitting assembly, and pressing. Each step may require one or more mechanisms to continue processing, resulting in a large number of devices, high initial investment costs, and a large footprint. Furthermore, during the processing of these multiple steps, when the tubular material completes one step and needs to be moved to the next, it is usually necessary to manually transfer the material from one piece of equipment to another. This results in low processing efficiency, high operating costs (requiring a large amount of human resources), and negative impacts on the quality of the tubular material processing (multiple manual movements of the material may affect its positioning accuracy, thereby increasing processing errors).

[0003] Therefore, based on the above-mentioned technical problems, this application proposes a multi-station assembly and pressing equipment that has a small footprint, reduces operating costs / initial investment costs, and improves production efficiency and processing quality. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-station assembly and pressing equipment that occupies a small area, reduces operating costs / initial investment costs, and improves production efficiency and processing quality.

[0005] To achieve the above objectives, the present invention provides a multi-station assembly pressing device, comprising a workbench, a first station, a second station, a third station, and a fourth station arranged sequentially along the X-axis, and a material transfer mechanism for switching the pipe material to be processed between adjacent stations. Each station and the material transfer mechanism are located on the workbench, and each station is equipped with a fixing clamp for securing the pipe material. The first and third stations are each equipped with a pressing mechanism for pressing the annular fitting to be assembled onto the end of the pipe material, and a feeding mechanism for supplying the annular fitting to the pressing mechanism. The second and fourth stations are each equipped with a pressing mechanism for pressing the end of the pipe material. According to preset design requirements, one or more stations from the first to the fourth station can be selectively activated once or multiple times to perform multiple processing operations on the end of the pipe material.

[0006] Furthermore, the material transfer mechanism includes a conveyor frame mounted on the workbench along the X-axis, at least one rotating guide rail extending along the X-axis, at least two rotating drive units fixed on the conveyor frame, and at least two clamping components for clamping the pipe material. The rotating guide rail is laid on the conveyor frame, and each clamping component is slidably connected to the rotating guide rail through a preset first-level sliding block. The movable end of each of the rotating drive units is connected to the corresponding first-level sliding block, and each of the rotating drive units is used to drive the corresponding clamping component to reciprocate along the X-axis.

[0007] Furthermore, each of the clamping components includes a sliding plate, a primary lifting guide rail extending along the Z-axis, a primary lifting drive unit, a support seat, a guide rod extending along the Y-axis, an adjusting member disposed on one end of the guide rod, a pair of clamps that open and close in opposite directions, and a clamping drive unit for driving the opening and closing action of the pair of clamps. One side of the sliding plate is connected to a primary sliding block, and the primary lifting guide rail is laid on the other side of the side mounting component. The support seat is slidably connected to the primary lifting guide rail through a preset secondary sliding block. The movable end of the primary lifting drive unit is connected to the corresponding secondary sliding block, and the primary lifting drive unit is used to drive the support seat to reciprocate along the Z-axis. The guide rod is installed at the bottom of the support seat, and the clamps are movably connected to the guide rod so that by rotating the adjusting member, the clamps can reciprocate along the Y-axis. The clamping drive unit is disposed on the clamps. The clamps are used to clamp the pipe material on the corresponding station's fixed fixture to move the pipe material to the fixed fixture of the next station.

[0008] Furthermore, the pressing mechanism includes a fixed base fixed to the worktable, a receiving seat fixed to one end of the fixed base, a loading drive unit, a connecting seat, a pressing assembly mounted on the connecting seat, at least one translation guide rail extending along the Y-axis, a translation drive unit mounted on the fixed base, a primary propulsion guide rail, and a propulsion drive unit mounted on the connecting seat. The feeding end of the receiving seat is connected to the discharging end of the feeding structure. The loading drive unit is mounted on the receiving seat, and the movable end of the loading drive unit is coaxially arranged with the discharging end of the receiving seat. The loading drive unit is used to press the ring-shaped parts to be assembled, which are received by the receiving seat, one by one onto the pressing seat. On the material assembly; the translation guide rail is laid on the fixed base, the connecting seat is slidably connected to the translation guide rail through a preset three-stage sliding block, the movable end of the translation drive unit is connected to the three-stage sliding block respectively, and the translation drive unit is used to drive the connecting seat to reciprocate along the X-axis direction; the first-stage push guide rail is laid on the connecting seat, the pressing assembly is slidably connected to the first-stage push guide rail through a preset four-stage sliding block, the movable end of the push drive unit is connected to the pressing assembly, and the push drive unit is used to drive the pressing assembly to reciprocate along the Y-axis direction, so that the pressing assembly presses the assembly ring fitting onto the end of the tube.

[0009] Furthermore, the pressing assembly includes a sliding seat, a pusher pin, a buffer spring, and a loading sleeve. The movable end of the pushing drive unit is connected to one end of the sliding seat, one end of the pusher pin is fixed to the other end of the sliding seat, and the other end of the pusher pin is movably connected to the loading sleeve. The buffer spring is sleeved on the outer circumferential surface of the pusher pin, and its two ends are respectively connected to the sliding seat and the loading sleeve. The loading sleeve is used to receive the ring-shaped part to be assembled pushed out by the loading drive unit and to pre-press and fix the tube when the pusher pin pushes the ring-shaped part to be assembled. The pusher pin is used to press the ring-shaped part to be assembled, which is clamped in the loading sleeve, onto the end of the tube under the drive of the pushing drive unit.

[0010] Furthermore, the pressing mechanism includes a fixed side seat fixed to the workbench, at least one secondary lifting guide rail extending along the Z-axis, a connecting side seat, a secondary lifting drive unit fixed to the fixed side seat, multiple pressing components arranged sequentially along the Z-axis, multiple secondary propulsion guide rails extending along the Y-axis, and a jacking component fixed to the fixed side seat. Each pressing component corresponds to a different pressing processing dimension. The secondary lifting guide rail is laid on the fixed side seat, and the connecting side seat is slidably connected to the secondary lifting guide rail via a preset five-stage sliding block. The movable end of the secondary lifting drive unit is connected to the connecting side seat, and the secondary lifting drive unit is used to drive the connecting side seat to reciprocate along the Z-axis direction to move the position of any pressing component in the Z-axis direction so that it is located at the same Z-axis position as the movable end of the pushing component; multiple secondary propulsion guide rails are laid at intervals along the Z-axis direction on the connecting side seat, and each pressing component is slidably connected to the corresponding secondary propulsion guide rail through a preset six-level sliding block, so that the pushing component pushes the pressing component, thereby realizing pressing processing on the end of the pipe.

[0011] Furthermore, the jacking assembly includes a support base installed on one side of the corresponding fixed fixture, at least one support rod, a mounting base installed on the fixed side seat, and a jacking drive unit installed on the mounting base. The jacking drive unit is used to jack the pressing assembly located at the same Z-axis height, causing it to move along the corresponding secondary propulsion guide rail, thereby achieving the purpose of pressing the end of the pipe. The support rod is erected between the connecting seat and the fixed side seat.

[0012] Furthermore, each of the pressing components includes a loading block, a pressing head, and two oppositely arranged limiting blocks. The pressing head is installed on one end of the loading block, and the two limiting blocks are installed on the other end of the loading block. The pressing head is used to press the end of the pipe material.

[0013] Furthermore, each of the limiting blocks has an L-shaped structure, and the inner L-shaped surfaces of the two limiting blocks together with the end face of the other end of the loading block form a limiting slide.

[0014] Furthermore, the pressing mechanism also includes at least one limiting slider and at least one connecting arm. One end of the connecting arm is connected to the fixed side seat, and the other end is connected to the limiting slider. The limiting slider is movably embedded in the limiting slide rail to relatively limit the offset of each pressing component in the X-axis and Y-axis directions.

[0015] The present invention adopts the above-mentioned solution, and its beneficial effects are as follows: By integrating the equipment used in multiple processes into one piece of equipment, the equipment floor space and initial investment costs are relatively reduced. Furthermore, the equipment is divided into corresponding workstations, each corresponding to a processing step used on the pipe material. Based on processing requirements, the mechanisms at the appropriate workstations can be selectively activated to sequentially process the pipe ends (e.g., fitting press-fitting, pressing, etc.). The processing sequence can also be adjusted; for example, the pipe ends can be sequentially processed by fitting press-fitting, pressing, fitting press-fitting, pressing, or pressing, fitting press-fitting, pressing, etc., offering high selectivity and strong combinability. Secondly, the equipment also integrates a material transfer mechanism, thus eliminating the need for extensive manpower to move / switch pipe materials between workstations, reducing equipment operating costs. Simultaneously, enabling the material transfer mechanism to move the pipe material ensures accurate positioning after movement, thereby reducing processing errors and guaranteeing product quality.

Detailed Implementation

[0033] To facilitate understanding of the present invention, a more complete description is given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0034] See appendix Figure 1-16 As shown (e.g.) Figure 1(As shown in the diagram, an XYZ axis reference coordinate system is established). In this embodiment, a multi-station assembly pressing device includes a workbench, a first station 1, a second station 2, a third station 3, and a fourth station 4 arranged sequentially along the X-axis, and a material transfer mechanism 5 for switching the pipe material 7 to be processed between adjacent stations. Each station and the material transfer mechanism 5 are located on the workbench, and each station is equipped with a fixing clamp 6 for fixing the pipe material 7. The first station 1 and the third station 3 are each equipped with a pressing mechanism 11 for pressing the annular fitting 8 to be assembled onto the end of the pipe material 7, and a feeding mechanism 12 for supplying the annular fitting 8 to the pressing mechanism 11. Furthermore, the feeding mechanism 12 used in this embodiment is a conventional mechanism, and can be referenced from existing patents (which can directly feed material laterally from a vibratory feeder to a linear track). Material handling mechanism 12-2020114327993), which will not be elaborated here; both the second station 2 and the fourth station 4 are equipped with pressing mechanisms 21 for pressing the ends of the pipe material 7. According to the preset design requirements, one or more stations from the first station 1 to the fourth station 4 can be selectively activated once or multiple times to perform multiple processing on the ends of the pipe material 7. Specifically, the pressing processing on the first station 1 or the third station 3 can be selectively performed (depending on the actual assembly requirements), so that the ends of the pipe material 7 are equipped with one or two annular fittings 8. When the pipe material 7 is on the second station 2 or the fourth station 4, one or more pressing processing can be performed. Moreover, the pressing size of each pressing processing can be different, thereby improving the adaptability and versatility of the equipment assembly / processing. In addition, before entering the first workstation 1, the tube material 7 is in a complete and undivided state and is stored in a roll. Through the preset cutting mechanism, the roll of tube material 7 is pre-processed by unwinding, shaping and dividing. Then, the divided tube material 7 is transferred to the first workstation 1 for processing by the material transfer mechanism 5 (the cutting mechanism can be found in the existing patent: A cutting, pipe forming and pipe pulling integrated machine-2019114157580, which will not be elaborated here). After the tube material 7 has completed the processing at the fourth workstation 4, it can be transferred to the pipe bending mechanism according to the actual processing needs (the bending mechanism can be found in the existing patent: A CNC pipe bending and forming device-2017102136762, which will not be elaborated here) or the tube material 7 can be directly output.

[0035] It should be noted that the process of pressing and processing (pipe workpieces) pipe material 7 typically includes multiple steps such as feeding, fitting assembly, and pressing. Each step may require one or more mechanisms to continue processing, resulting in the disadvantages of a large number of equipment, high initial investment costs, and a large footprint. Furthermore, during the processing of the above multiple steps, when the pipe material 7 completes one step and needs to be moved to the next step, it is usually necessary to manually transfer the pipe material 7 from one piece of equipment to another. This results in low processing efficiency, high operating costs (requiring a lot of human resources), and affects the processing quality of the pipe material 7 (multiple manual movements of the pipe material 7 may affect its positioning accuracy, thereby increasing processing errors).

[0036] In this embodiment, by integrating the equipment used in multiple processes into one device, the equipment footprint and initial investment costs are relatively reduced (the cost of using the integrated device in this embodiment is lower than that of using multiple devices). The device is also divided into workstations, each corresponding to a processing step of the pipe material 7. Depending on processing requirements, the mechanisms at the corresponding workstations can be selectively activated to sequentially process the ends of the pipe material 7 (e.g., fitting press-fitting, pressing, etc.). The processing sequence can also be adjusted; for example, the ends of the pipe material 7 can be sequentially processed by fitting press-fitting, pressing, fitting press-fitting, or pressing, fitting press-fitting, etc., offering high selectivity and strong combinability. Furthermore, this device integrates a material transfer mechanism 5, enabling the movement / switching of the pipe material 7 between workstations without requiring a large amount of manpower, reducing equipment operating costs. Simultaneously, the material transfer mechanism 5 ensures the positioning accuracy of the pipe material 7 after movement, thereby reducing processing errors and guaranteeing product quality.

[0037] The annular component 8 mentioned in this embodiment can be a washer, nut, rubber ring, or other component. Furthermore, the annular component 8 to be pressed into the first station 1 and the third station 3 can be selected according to the actual assembly requirements.

[0038] In this embodiment, after the end of the pipe 7 is processed at one or more of the stations 1-4 described above, it can form the following shapes: Form 1 (see appendix) Figure 14 As shown), the outer circumferential surface of the end of the pipe 7 is provided with a first step 71, an annular fitting 8, a second step 72, an annular fitting 8 and a third step 73 from top to bottom. The processing route for the pipe 7 to form this shape can be the first station 1, the second station 2, the third station 3, the fourth station 4 and the third station 3. Form 2 (see appendix) Figure 15As shown), the outer circumferential surface of the end of the pipe 7 is provided with a first step 71, a second step 72 and an annular fitting 8 from top to bottom. The processing route for the pipe 7 to form this shape can be the first station 1, the first station 1, the second station 2 and the third station 3. Form 3 (see appendix) Figure 16 As shown), the outer periphery of the end of the tube 7 is provided with a first step 71, an annular fitting 8 and a second step 72 from top to bottom. The processing route for the tube 7 to form this shape can be the first station 1, the second station 2 and the third station 3. The specific number, size, and location of the steps, as well as the number and location of the ring-shaped accessories 8, can all be set according to actual needs, and will not be shown in detail here.

[0039] See appendix Figure 5-6 As shown, in this embodiment, each fixing fixture 6 includes a fixture body 61, a U-shaped locking block 62, two clamping rails 63, two opposing clamping molds 64, two connecting blocks 65, and a clamping drive unit 66. The fixture body 61 has a placement cavity that extends along the Z-axis and allows the U-shaped locking block 62 to be movably fitted. The two clamping rails 63 are respectively installed on the two inner inclined surfaces of the U-shaped locking block 62, and each clamping mold 64 is slidably connected to the clamping rail 63 through a preset inclined slider. The inner inclined surfaces are inclined from the inside to the outside, so that the two inner inclined surfaces of the U-shaped locking block 62 gradually narrow from top to bottom along the Z-axis (that is, as the U-shaped locking block 62 moves in the Z-axis direction, its inner inclined surfaces can drive the two clamping molds 64 to move closer or further apart, so as to realize the clamping or loosening function of the fixing fixture 6); the clamping drive unit 66... The clamping drive unit 66 is installed at the bottom of the fixture body 61. The movable end of the clamping drive unit 66 is connected to the U-shaped locking block 62. The clamping drive unit 66 is used to drive the U-shaped locking block 62 to reciprocate along the Z-axis. When the clamping drive unit 66 pushes the U-shaped locking block 62 upward along the Z-axis, it drives the two clamping molds 64 (slidably connected to the inclined clamping track 63) to move closer together, thus clamping the pipe material 7. When the clamping drive unit 66 pulls the U-shaped locking block 62 downward along the Z-axis, it drives the two clamping molds 64 (slidably connected to the inclined clamping track 63) to move further apart, thus releasing the pipe material 7. This achieves a stable clamping function for the pipe material 7, ensuring its processing quality, and a timely release function (avoiding damage to the pipe material 7 due to untimely release), ensuring the smoothness of the pipe material 7 when switching processing positions.

[0040] The top of the clamp body 61 has an opening 611 that runs through it along its thickness direction and allows the two clamping molds 64 to slide relative to each other, thus providing space for the clamping molds 64 to move. Secondly, the top of the clamp body 61 also has a positioning groove 612 that runs through it along its length direction. The positioning groove 612 is used to position the inclined slider relative to each other, that is, to relatively restrict the movement of the inclined slider in the Z-axis direction, so that the inclined slider moves along the clamping track 63 (moving relative to each other along its length direction) as the U-shaped locking block 62 moves in the Z-axis direction, thereby driving the clamping molds 64 to move closer or further apart.

[0041] See appendix Figure 2-4 As shown, in this embodiment, the material transfer mechanism 5 includes a conveyor frame 51 mounted on the workbench along the X-axis, at least one rotating guide rail 52 extending along the X-axis (preferably two rotating guide rails 52 spaced apart along the Z-axis), at least two rotating drive units 53 fixed on the conveyor frame 51, and at least two clamping components 54 for clamping the pipe material 7. The number of clamping components 54 can be set according to actual conditions (for example, in cases of high production efficiency, one clamping component 54 can be set at each station, so that when the pipe material 7 completes processing at one station, it can be clamped and transferred to the next station, and simultaneously the next pipe material 7 can be clamped and transferred to this station for processing). This is not discussed here. There are no excessive restrictions; secondly, the number of the aforementioned clamping components 54 is preferably consistent with the number of the operation drive units 53, so as to achieve precise control of the displacement of each clamping component 54 (the specific number of operation drive units 53 is not fully shown in the figure); the operation guide rail 52 is laid on the conveyor frame 51, and each clamping component 54 is slidably connected to the operation guide rail 52 through a preset first-level sliding block 55. The movable end of each operation drive unit 53 is connected to the corresponding first-level sliding block 55, and each operation drive unit 53 is used to drive the corresponding clamping component 54 to reciprocate along the X-axis direction, so as to realize the transfer of the pipe material 7 between each station, relatively reducing manual intervention and reducing the cost of use (human resources).

[0042] See appendix Figure 4As shown, in this embodiment, each clamping assembly 54 includes a sliding plate 541, a primary lifting guide rail 542 extending along the Z-axis, a primary lifting drive unit 543, a bearing seat 544, a guide rod 545 extending along the Y-axis, an adjusting member 546 disposed on one end of the guide rod 545, a pair of clamps 547 opening and closing in opposite directions, and a clamping drive unit 548 driving the pair of clamps 547 to open and close. One side of the sliding plate 541 is connected to a primary sliding block 55, and the primary lifting guide rail 542 is laid on the other side of the side mounting component. The bearing seat 544 is slidably connected to the primary lifting guide rail 542 through a preset secondary sliding block 549. The movable end of the primary lifting drive unit 543 is connected to the corresponding secondary sliding block 549, and the primary lifting drive unit 543 is used to drive the bearing seat 544 to reciprocate along the Z-axis. The guide rod 545 is installed at the bottom of the bearing seat 544, and the clamps 547 are movably connected to the guide rod 545. To achieve the goal of reciprocating movement of clamp 547 along the Y-axis by rotating the adjusting component 546 (here, a lead screw drive can be used to drive the guide rod 545 to drive the clamp 547 to reciprocate along the Y-axis, and the guide rod 545 is preferably a lead screw, and the clamp 547 is provided with a threaded configuration that drives the lead screw), considering that the clampable part of different specifications of pipe 7 may be different (the position of force balance of pipe 7 needs to be determined to ensure that after clamping, the clamp 547 will not cause the other end of the pipe 7 to drop because the clamping part is too close to its end, thus affecting the clamping effect of the fixing fixture 6 on the pipe 7), it is necessary to adjust the clamping part of clamp 547 on pipe 7 according to the actual size of different specifications of pipe 7; thus, by twisting the adjusting component 546 to drive the guide rod 545 to drive the clamp 547 along the Y-axis, so that the clamp 547 corresponds to the clamping part of the target pipe 7, so that the clamp 547 can stably clamp the pipe 7.

[0043] See appendix Figure 4 As shown, the clamping drive unit 548 is further disposed on the clamp 547; the clamp 547 is used to clamp the pipe material 7 on the corresponding station fixed fixture 6; when the pipe material 7 at one station completes the processing at that station, under the drive of the first-level lifting drive unit 543, the clamp 547 performs a clamping action on the clamping part of the pipe material 7; after the clamp 547 completes the clamping action and the fixed fixture 6 at that station releases the pipe material 7, under the drive of the first-level lifting drive unit 543, the pipe material 7 is disengaged from that station, so as to move the pipe material 7 to the fixed fixture 6 of the next station, and perform the processing / discharge of the next station accordingly.

[0044] See appendix Figure 7-9As shown, in this embodiment, the pressing mechanism 11 includes a fixed base 111 fixed to the workbench, a receiving seat 112 fixed to one end of the fixed base 111, a loading drive unit 113, a connecting seat 114, a pressing assembly 115 mounted on the connecting seat 114, at least one, preferably two, translation guide rails 116 extending along the Y-axis, a translation drive unit 117 mounted on the fixed base 111, a first-stage propulsion guide rail 118, and a propulsion drive unit 119 mounted on the connecting seat 114. The feeding end of the receiving seat 112 is connected to the discharging end of the feeding structure. The loading drive unit 113 is mounted on the receiving seat 112, and the movable end of the loading drive unit 113 is coaxially arranged with the discharging end of the receiving seat 112. The material drive unit 113 is used to press the ring-shaped parts 8 to be assembled, which are received by the receiving seat 112, onto the pressing assembly 115 one by one (feeding). The receiving seat 112 is configured to provide a fixed feeding point, while the material drive unit 113 is configured to perform the feeding action. Through the cooperation of the receiving seat 112 and the feeding mechanism 12, the material is continuously fed to the pressing assembly 115. The translation guide rail 116 is laid on the fixed base 111. The connecting seat 114 is slidably connected to the translation guide rail 116 through the preset three-stage sliding block 1141. The movable end of the translation drive unit 117 is connected to the three-stage sliding block 1141 respectively, and the translation drive unit 117 is used to drive the connecting seat 114 to reciprocate along the X-axis direction.

[0045] Considering that the feeding position and the pressing position are not in the same X-axis direction, and in order to save equipment costs (setting up both the loading mechanism and the feeding mechanism at the same time would greatly increase the equipment cost and the overall footprint, resulting in low economic efficiency), by setting up the above-mentioned translation guide rail 116 and translation drive unit 117, the feeding component can change its position in the X-axis direction (switching between the feeding position and the pressing position), so that the feeding component can be aligned with the discharge end of the receiving seat 112 and the end of the tube 7 held by the fixing clamp 6, respectively. This is to meet the purpose of the feeding component in receiving / clamping the ring-shaped accessory 8 to be assembled pushed by the loading drive unit 113 and pressing the ring-shaped accessory 8 to be assembled onto the end of the tube 7. The first-stage propulsion guide rail 118 is laid on the connecting seat 114. The pressing assembly 115 is slidably connected to the first-stage propulsion guide rail 118 through a preset four-stage sliding block 1155. The movable end of the propulsion drive unit 119 is connected to the pressing assembly 115, and the push drive unit is used to drive the pressing assembly 115 to reciprocate along the Y-axis direction, so that the pressing assembly 115 presses the assembly ring accessory 8 onto the end of the tube 7.

[0046] Furthermore, the pressing assembly 115 includes a sliding seat 1151, a pusher pin 1152, a buffer spring 1153, and a loading sleeve 1154. The movable end of the pushing drive unit is connected to one end of the sliding seat 1151 to achieve the purpose of driving the sliding seat 1151 to reciprocate along the Y-axis direction. The sliding seat 1151 is connected to a four-stage sliding block 1155. One end of the pusher pin 1152 is fixed to the other end of the sliding seat 1151, and the other end of the pusher pin 1152 is movably connected to the loading sleeve 1154. The buffer spring 115... 3 are sleeved on the outer circumferential surface of push pin 1152, and their two ends are respectively connected to sliding seat 1151 and loading sleeve 1154; loading sleeve 1154 is used to receive the ring-shaped part 8 to be assembled pushed out by loading drive unit 113 and to pre-press and fix tube 7 when push pin 1152 pushes the ring-shaped part 8 to be assembled; push pin 1152 is used to align coaxially with tube 7 on fixed fixture 6 at this station, and under the drive of push drive unit 119, press the ring-shaped part 8 to be assembled, which is clamped in loading sleeve 1154, onto the end of tube 7.

[0047] See appendix Figure 10-11 As shown, in this embodiment, the pressing mechanism 21 includes a fixed side seat 211 fixed to the workbench, at least one, preferably two, secondary lifting guide rails 212 extending along the Z-axis, a connecting side seat 213, a secondary lifting drive unit 214 fixed to the fixed side seat 211, multiple pressing components 215 arranged sequentially along the Z-axis, multiple secondary propulsion guide rails 216 extending along the Y-axis, and a pushing component 217 fixed to the fixed side seat 211. The pressing processing dimensions corresponding to each pressing component 215 are different, and the pressing dimensions of the multiple pressing components 215 can be set to increase / decrease sequentially from top to bottom. The specific dimension range can be set according to the actual situation (e.g., φ2 mm - φ...). (10mm), not detailed here; the secondary lifting guide rail 212 is laid on the fixed side seat 211, and the connecting side seat 213 is slidably connected to the secondary lifting guide rail 212 through a preset five-level sliding block 2131. The movable end of the secondary lifting drive unit 214 is connected to the connecting side seat 213, and the secondary lifting drive unit 214 is used to drive the connecting side seat 213 to reciprocate along the Z-axis direction, so as to move the position of any pressing component 215 in the Z-axis direction, so that it is located at the same Z-axis position as the movable end of the pushing component 217; that is, according to the requirements of the pipe pressing processing size, the position of the corresponding pressing component 215 in the Z-axis direction can be adjusted so that it is located at the same Z-axis height as the movable end of the pushing component 217, thereby realizing the purpose of switching different pressing sizes for pressing processing and improving the processing range; Multiple secondary propulsion guide rails 216 are laid at intervals along the Z-axis on the connecting side seat 213, thus providing sufficient movement space for each pressing component 215 and preventing the pressing components 215 from colliding with each other or obstructing their movement due to insufficient movement space, which would affect the normal progress of pressing. Each pressing component 215 is slidably connected to the corresponding secondary propulsion guide rail 216 through a preset six-level sliding block 2155, so that (after the jacking component 217 is located at the same Z-axis position as any pressing component 215), the jacking component 217 pushes the pressing component 215, thereby realizing the pressing of the end of the pipe 7.

[0048] See appendix Figure 10-13 As shown, in this embodiment, the pushing assembly 217 includes a support base 2171 installed on one side of the corresponding fixed clamp 6, at least one, preferably two, support rods 2172, a mounting base 2173 installed on the fixed side seat 211, and a pressing drive unit 2174 installed on the mounting base 2173. The pressing drive unit 2174 is used to push the pressing assembly 215 located at the same Z-axis height, causing it to move along the corresponding secondary propulsion guide rail 216, thereby achieving the purpose of pressing the end of the pipe 7. Considering that when pressing the pipe 7, the pressing drive unit 2174 is only fixed on one side. The first side is in a suspended state (connected to the fixed side seat 211 via mounting base 2173), while the other side is in a suspended state. During the pressing process, the moving end is easily displaced by the reaction force generated by the pressing, which affects the normal pushing process of the pressing assembly 215. Therefore, by setting support base 2171 and support rod 2172, the support rod 2172 is mounted between the connecting base 114 and the fixed side seat 211. When the pressing drive unit 2174 pushes a pressing head 2152, the connecting base 114 and the fixed side seat 211 provide support and stability to the whole mechanism, thus avoiding affecting the normal pressing process.

[0049] See appendix Figure 12-13 As shown, each pressing assembly 215 further includes a loading block 2151, a pressing head 2152, and two oppositely arranged limiting blocks 2153. The pressing head 2152 is installed on one end of the loading block 2151, and the two limiting blocks 2153 are installed on the other end of the loading block 2151. One side of the loading block 2151 is slidably connected to the corresponding secondary propulsion guide rail 216 through a six-stage sliding block 2155. The pressing head 2152 is used to press the end of the pipe 7. The split structure makes it easier to replace the damaged pressing head 2152, reducing the difficulty of maintenance, or to replace it with a pressing head 2152 of another size range, improving the convenience of replacement.

[0050] Furthermore, each limiting block 2153 has an L-shaped structure, and the inner L-shaped surfaces of two limiting blocks 2153 together with the end face of the other end of the loading block 2151 form a limiting slide 2154. The pressing mechanism 21 also includes at least one, preferably two, limiting sliders 218 and at least one, preferably four, connecting arms 219. One end of the connecting arm 219 is connected to the fixed side seat 211, and the other end is connected to the limiting slider 218. One limiting slider 218 is connected to... Two connecting arms 219 form a group, located above and below the fixed side seat 211 respectively, so that multiple pressing components 215 arranged sequentially along the Z-axis direction remain at the same X-axis and Y-axis positions (the Y-axis position only changes when the jacking component 217 jacks a pressing component 215); the limiting slider 218 is movably fitted on the limiting slide rail 2154 to relatively limit the offset of each pressing component 215 in the X-axis and Y-axis directions. At the same time, the aforementioned jacking drive unit... The movable end of unit 2174 is also movably fitted onto the limiting slide 2154 (the movable end is provided with a snap-fit ​​structure that can engage with the limiting slide 2154); by making the movable end of the aforementioned top-pressing drive unit 2174 movably fitted onto the limiting slide 2154 of each pier pressing component 215, after the top-pressing drive unit 2174 completes the jacking process (after completing the pier pressing), and the limiting slide 2154 is snapped onto the movable end of the top-pressing drive unit 2174, the top-pressing drive unit 2174 moves along with the jacking drive unit 2174. The pullback of element 2174 drives the pier pressing component 215 to return to the position before the push, eliminating the need for an additional return / reset mechanism, thus reducing the equipment footprint and cost and simplifying the operation process. Specifically, the movable end of the push pressing drive unit 2174 can only be switched from the limiting slide 2154 of one pier pressing component 215 to the limiting slide 2154 of another pier pressing component 215 when the secondary lifting drive unit 214 drives the connecting side seat 213 to lift.
