The worktable is fixedly installed on the top of the circular base. The first feeding component, the installation component, the second feeding component, and the unloading component are arranged clockwise along the circular base. The feeding component uses a plier body feeding robotic arm, which works in conjunction with a motor. The feeding time is long and it occupies a large space. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic assembly device for wire cutters, so as to solve the defects of high manual labor intensity and low assembly efficiency in the prior art.

[0005] To achieve the above objectives, the present invention is implemented using the following technical solution: an automatic assembly device for wire cutters, used for assembling the left and right halves of wire cutters, including a rotatably configured indexing rotary component; The indexing rotary component has five accompanying fixtures mounted in a circular array on its surface. Each accompanying fixture has a left half cavity and a right half cavity with a central through hole. The central through holes of the five accompanying fixtures are coaxial with the five through holes on the rotary table of the indexing rotary component. The indexing rotary component has a first station, a second station, a third station, a fourth station, and a fifth station arranged equidistantly in a clockwise circumferential direction. Each station corresponds to a traveling fixture. A pressing component is provided between the first station and the second station, corresponding to the side position of the indexing rotary component. Rotating the indexing rotary component works in conjunction with the first station, the second station, and the pressing component to feed the left and right halves of the piece into the corresponding traveling fixture. The indexing rotary component is rotated in conjunction with the third and fourth workstations to install and compact the rotating shafts into the center holes of the left and right halves; the fifth workstation is used to transfer the wire cutters installed in the accompanying fixture.

[0006] In a further embodiment of the present invention, the indexing rotary component includes a rotary table and an indexing drive assembly for driving the rotary table to rotate. The rotary worktable includes a rotary table and an I-shaped fixed frame. The rotary table is rotatably mounted on the I-shaped fixed frame via a rotary bearing. Two anti-reverse stop blocks are installed at 180-degree intervals on the reverse side of the rotary table. Two anti-reverse kits are correspondingly installed at 180-degree intervals on the top side of the I-shaped fixed frame. The cooperation of the anti-reverse stop blocks and anti-reverse kits prevents the rotary table from reversing. The indexing assembly is installed on the reverse side of the rotary table. The indexing assembly includes a frame body and a T-shaped slider fixed to the reverse side of the rotary table. The frame body is provided with a T-shaped groove. The T-shaped slider is elastically set in the T-shaped groove by a first telescopic spring. The T-shaped slider is provided with a countersunk hole. A drive column is elastically set in the countersunk hole by a second telescopic spring. The indexing drive assembly includes an indexing rodless cylinder, which is supported by an indexing bracket. An indexing drive block is mounted on the slider of the indexing rodless cylinder. The indexing drive block is a half-hollow cylinder with a chamfered outer edge. The inner or outer edge of the indexing drive block abuts against the drive column.

[0007] In a further embodiment, the anti-reverse kit includes a base, which is fixed to the top surface of the I-shaped fixing frame. The side of the base facing the turntable has a countersunk hole, and an anti-reverse cylinder is installed in the countersunk hole through a No. 3 telescopic spring. The rounded end of the anti-reverse cylinder points towards the turntable. The anti-reverse cylinder abuts against the outer or inner edge of the anti-reverse stop block.

[0008] In a further embodiment of the present invention, the first workstation includes a first platform, which is supported by a first retractable support leg. A first forming through hole matching the left half of the workpiece is provided on the first platform near the rotary table. The first forming through hole movably abuts against the left half cavity of the corresponding accompanying fixture. A first telescopic cylinder is installed on the first platform away from the rotary table. A left half storage unit with a second forming through hole is fixed on the first platform between the first telescopic cylinder and the first forming through hole, and a gap exists between the left half storage unit and the first platform. A first forming pusher is also fixed to one end of the piston rod of the first telescopic cylinder pointing towards the gap.

[0009] In a further embodiment, the second workstation has the same structure as the first workstation. In the second workstation, a third forming through hole is provided at the position of the first forming through hole corresponding to the first workstation; a fourth forming through hole is provided at the position of the second forming through hole, and the second and fourth forming through holes are matched with the right half piece.

[0010] In a further embodiment of the present invention, the third station includes a separation component and a gripping component, wherein the gripping component grips and transfers the rotating shaft in the separation component into the central holes of the left and right halves; The separation component includes a separation barrel containing a rotating shaft. The separation barrel is supported by a separation bracket. Multiple rollers are rotatably mounted in a circular array on the top of the separation bracket. A separation motor is mounted on the bottom surface of the separation bracket, and the output shaft of the separation motor rotates through the end of the separation bracket and connects to a separation turntable. The bottom surface of the separation turntable abuts against the rollers. A position adjustment kit is connected through the discharge port on the side wall of the separation barrel, and the position adjustment kit limits the rotation of the rotating shaft emitted by the separation barrel.

[0011] The gripping assembly includes a rodless cylinder No. 3, which is supported by a column No. 3. The telescopic cylinder No. 3 is mounted on the slider of the rodless cylinder No. 3, and a vacuum suction cup No. 3 is installed at the end of the piston rod of the telescopic cylinder No. 3.

[0012] In a further embodiment, the posture adjustment kit includes an inclined slide and a horizontal slide. The inclined slide is connected through the discharge port of the separation barrel, and the end of the inclined slide away from the discharge port is connected to the horizontal slide. The width of the inner groove of the inclined slide is greater than the diameter of the end of the rotating shaft cap, and the width of the inner groove of the horizontal slide is greater than the diameter of the cylindrical section of the rotating shaft and smaller than the diameter of the end of the rotating shaft cap.

[0013] In a further embodiment of the present invention, the fourth working station includes a fourth support, a lower hydraulic cylinder, and an upper hydraulic cylinder. The lower hydraulic cylinder is fixed to the middle suspension beam of the fourth support, and the piston rod of the lower hydraulic cylinder extends upward through the middle suspension beam. The upper hydraulic cylinder is fixed to the upper suspension beam of the fourth support, and the piston rod of the upper hydraulic cylinder extends downward through the upper suspension beam. The piston rods of the upper hydraulic cylinder and the lower hydraulic cylinder are coaxial in space.

[0014] In a further embodiment of the present invention, the fifth workstation includes a fifth support and a fifth rotary cylinder. The fifth rotary cylinder is mounted on the top of the fifth support via a cylinder mounting bracket. The fifth support passes through the cylinder mounting bracket and is rotatably mounted with a rotating arm via a thrust bearing and a radial bearing. The rotating arm extends horizontally outward, and a fifth telescopic cylinder is mounted on the rotating arm. The piston rod of the fifth telescopic cylinder passes downward through the rotating arm and is connected to a vacuum suction cup. The rotation shaft of the fifth rotary cylinder is connected to the hollow cylinder of the rotating arm.

[0015] In a further embodiment of the present invention, the pressing assembly includes a double-rod cylinder, which is fixedly supported by a No. 9 bracket, and the piston rod end of the double-rod cylinder is vertically downward and fitted with an arc-shaped pressure plate.

[0016] According to the above technical solution, the present invention has at least the following beneficial effects: 1. The storage compartments of the left and right halves of the storage compartments are respectively made of the left and right halves of the shaped structure storage wire cutters. Compared with traditional storage compartments, this ensures more accurate and convenient storage of parts. 2. By using the forming pusher and forming through hole, the left and right halves of the wire cutters are fed into the left and right cavities of the accompanying clamp respectively by their own weight. Compared with the traditional robotic gripping method, the structure is simpler and the efficiency is higher. 3. By utilizing the structural characteristics of the rotating shaft, the posture adjustment of the rotating shaft is realized, avoiding the shortcomings of using sensing devices to identify the posture of the rotating shaft and then using a robotic arm to adjust the posture, which results in high cost and complex structure; 4. The piston rods of the lower and upper hydraulic cylinders simultaneously squeeze the rotating shaft in the center hole of the left and right halves of the wire cutter, thus compacting the rotating shaft. This avoids the excessive pressure on the slewing bearing caused by the traditional method of using a single hydraulic cylinder to squeeze the rotating shaft, which would shorten the service life of the slewing bearing.

[0017] 5. The slider of the indexing rodless cylinder moves one stroke, and the rotary table completes one indexing. Compared with the traditional indexing achieved by frequently starting and stopping the motor, this equipment is more accurate in indexing; compared with the fixed indexing time interval of the traditional indexing mechanism, this equipment has greater flexibility.

[0018] 6. During assembly, the pressing component presses down the No. 1 water platform of the first station and the No. 2 water platform of the second station. The No. 1 water platform of the first station and the No. 2 water platform of the second station are respectively in close contact with the upper surface of the accompanying fixture. This allows the first station to accurately push the left half of the wire cutter into the left half cavity of the accompanying fixture, and the second station to accurately push the right half of the wire cutter into the right half cavity of the accompanying fixture, greatly improving the success rate of assembly.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] It should be noted that in the description of this invention, the terms "front," "rear," "left," "right," "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing the invention and do not require the invention to be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention. The terms "front," "rear," "left," "right," "upper," and "lower" used in the description of this invention refer to the directions shown in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] like Figure 1 , Figure 2 , Figure 14 and Figure 22As shown, an automatic wire cutter assembly device includes a first station 1, a second station 2, a third station 3, a fourth station 4, a fifth station 5, an indexing rotary component 6, and a pressing component 9. The first station 1, the second station 2, the third station 3, the fourth station 4, and the fifth station 5 are arranged at equal intervals around the indexing rotary component 6. The pressing component 9 is arranged between the first station 1 and the second station 2. The rotary table 62 of the indexing rotary component 6 has five through holes 62.1 machined in a circular array. Five accompanying fixtures 8 are arranged in a circular array on the rotary table 62 of the indexing rotary component 6. The central through holes 83 of the five accompanying fixtures 8 are coaxial with the five through holes 62.1 on the rotary table 62. During assembly, the pressing component 9 presses down the first platform 101 of the first station 1 and the second platform 201 of the second station 2. The first platform 101 of the first station 1 and the second platform 201 of the second station 2 are respectively pressed tightly against the upper surface of the accompanying fixture 8, so that the first station 1 accurately pushes the left half 71 of the wire cutter into the left half cavity 81 of the accompanying fixture 8, and the second station 2 accurately pushes the right half 72 of the wire cutter into the right half cavity 82 of the accompanying fixture 8. The third station 3 is used to place the rotating shaft 73 into the center hole of the left half 71 and the right half 72 of the wire cutter. The fourth station 4 is used to press the rotating shaft 73 placed in the center hole of the left half 71 and the right half 72 of the wire cutter. The fifth station 5 removes the assembled wire cutter 7, so that the accompanying fixture 8 can be used for the assembly of the next wire cutter.

[0025] like Figure 3 and Figure 4As shown, the first workstation 1 includes a platform 101, a left half storage unit 102, a telescopic cylinder 103, a forming pusher 104, and a telescopic support leg. The telescopic support leg includes a square rod 105, a shoe 106, and a spring 107. The square rod 105 is inserted into the shoe 106, and the spring 107 is positioned between the bottom of the square rod 105 and the shoe 106. Under external force, the square rod 105 can move within the shoe 106, forming the telescopic support leg. Two telescopic support legs are installed on one side of the platform 101, forming a cantilever support frame. A first forming through hole 101.1 is machined on platform 101. The shape of the first forming through hole 101.1 is the same as the cross-sectional shape of the left half piece 71. A first stop post 101.2 is machined in front of the first forming through hole 101.2. The middle of the left half piece storage 102 is a second forming through hole 102.2. The shape of the second forming through hole 102.2 is the same as the cross-sectional shape of the left half piece 71. The left half piece storage 102 is installed on the upper surface of platform 101. There is a first gap 102.1 between the bottom surface of the second forming through hole 102.2 of the left half piece storage 102 and the top surface of platform 101. The first gap 102.1 is slightly larger than the thickness of the left half piece 71. A first telescopic cylinder 103 is installed on the upper surface of platform 101 on the other side of the left half piece storage 102. A first forming pusher 104 is installed at the end of the piston rod of the first telescopic cylinder 103. When the piston rod of the first telescopic cylinder 103 extends, it pushes the left half 71, which is located at the bottom of the left half storage 102, forward through the first forming pusher 104. Then, it falls into the left half cavity 81 of the accompanying clamp 8 on the rotary table 62 through the first forming through hole 101.1. The first stop 101.2 can effectively prevent the left half 71 from flying out due to excessive speed when the first forming pusher 104 pushes the left half 71, which is located at the bottom of the left half storage 102.

[0026] like Figure 5As shown, the second workstation 2 includes a second platform 201, a right half storage unit 202, a second telescopic cylinder 203, a second forming pusher 204, and a second telescopic support leg 205. The structure of the second telescopic support leg 205 is the same as that of the first telescopic support leg in the first workstation 1. Two second telescopic support legs 205 are installed on one side of the second platform 201, forming a cantilever support frame. A third forming through hole 201.1 is machined on the second platform 201. The shape of the third forming through hole 201.1 is the same as the cross-sectional shape of the right half 72. A second stop post 201.2 is machined in front of the third forming through hole 201.1. The right half of the storage unit 202 has a No. 4 forming through hole 202.2 in the middle. The shape of the No. 4 forming through hole 202.2 is the same as the cross-sectional shape of the right half 72. The right half of the storage unit 202 is installed on the upper surface of the No. 2 platform 201. There is a No. 2 gap 202.1 between the bottom surface of the No. 4 forming through hole 202.2 of the right half of the storage unit 202 and the upper surface of the No. 2 platform 201. The No. 2 gap 202.1 is slightly larger than the thickness of the right half 72. The No. 2 telescopic cylinder 203 is installed on the upper surface of the No. 2 platform 201 on the other side of the right half of the storage unit 202. The No. 2 forming pusher 204 is installed at the end of the piston rod of the No. 2 telescopic cylinder 203. When the piston rod of the second telescopic cylinder 203 extends, it pushes the right half 72, which is located at the bottom of the right half storage 202, forward through the second forming pusher 204. Then, it falls into the right half cavity 82 of the accompanying clamp 8 on the rotary table 62 through the third forming through hole 201.1. The second stop 201.2 can effectively prevent the right half 72 from flying out due to excessive speed when the second forming pusher 204 pushes the right half 72, which is located at the bottom of the right half storage 202.

[0027] like Figure 6 As shown, the third station 3 includes a separation component 31 and a gripping component 32. The separation component 31 separates the disordered rotating shafts 73 and arranges them in a specific position. The gripping component 32 grips the rotating shafts 73 and places them into the center holes of the left half 71 and the right half 72 of the wire cutters 7.

[0028] like Figure 7 and Figure 8As shown, the separation component 31 includes a separation bracket 311, a separation bucket 312, a position adjustment kit, a separation motor 315, rollers 316, and a separation turntable 317. Four rollers 316 are arranged in a circular array on the top of the separation bracket 311. The separation turntable 317 is placed on the rollers 316. The separation motor 315 is mounted on the separation bracket 311. The output shaft of the separation motor 315 is connected to the central drive shaft of the separation turntable 317 via a coupling. The separation bucket 312 is placed on the top surface of the separation bracket 311. The separation turntable 317 has a slight taper and circular grooves are machined around its circumference. The separation bucket 312 and the separation turntable 317 are rotatably connected circumferentially via ball bearings 318. When the separation motor 315 rotates, it drives the separation turntable 317 to rotate. Under the action of centrifugal force, the rotating shaft 73 flows out sequentially from the discharge port of the separation bucket 312. The position adjustment kit adjusts the rotating shaft 73 flowing out of the discharge port of the separation bucket 312 into a specific position for arrangement.

[0029] like Figure 9 and Figure 10 As shown, the pose adjustment kit includes an inclined slide 313 and a horizontal slide 314. The width of the inner groove of the inclined slide 313 is slightly larger than the diameter of the cap end of the pivot 73, so that the pivot 73 can roll down smoothly under the action of gravity. The width of the inner groove of the horizontal slide 314 is slightly larger than the diameter of the cylindrical section of the pivot 73 but smaller than the diameter of the cap end of the pivot 73, so that the pivot 73 rolling down from the inclined slide 313 can only fall into the horizontal slide 314 with the cap end facing upward. The pivot 73 that rolls down later will push the previous pivot 73 forward along the horizontal slide 314, so that the pivots 73 are arranged in a specific pose in the horizontal slide 314.

[0030] like Figure 11 As shown, the gripping assembly 32 includes a third column 321, a third rodless cylinder 322, a third telescopic cylinder 323, and a third vacuum suction cup 324. The third rodless cylinder 322 is mounted on the cantilever beam of the third column 321, the third telescopic cylinder 323 is mounted on the slider of the third rodless cylinder 322, and the third vacuum suction cup 324 is mounted on the end of the piston rod of the third telescopic cylinder 323.

[0031] like Figure 12 As shown, the fourth station 4 includes a lower hydraulic cylinder 401, an upper hydraulic cylinder 402, and a fourth support 403. The lower hydraulic cylinder 401 is mounted on the middle cantilever beam of the fourth support 403, and its piston rod passes through a through hole in the middle cantilever beam of the fourth support 403. The upper hydraulic cylinder 402 is mounted on the upper cantilever beam of the fourth support 403, and its piston rod passes through a through hole in the upper cantilever beam of the fourth support 403. The piston rods of the lower hydraulic cylinder 401 and the upper hydraulic cylinder 402 are coaxial in spatial position.

[0032] like Figure 13As shown, the fifth station 5 includes a vacuum suction cup 501, a rotating arm 502, a telescopic cylinder 503, a rotary cylinder 504, and a support 507. One end of the rotating arm 502 is a hollow cylinder, which is rotatably mounted on the cylindrical shaft of the support 507 via a thrust bearing 506 and a radial bearing (not shown in the figure). The other end of the rotating arm 502 is equipped with the telescopic cylinder 503, and the piston rod of the telescopic cylinder 503 is equipped with the vacuum suction cup 501. The rotary cylinder 504 is mounted on the top of the support 507 via a cylinder mounting bracket 505. The rotation shaft of the rotary cylinder 504 is connected to the hollow cylindrical end of the rotating arm 502. The rotation of the rotation shaft of the rotary cylinder 504 drives the rotating arm 502 to rotate around the cylindrical shaft of the support 507.

[0033] like Figures 14 to 16 As shown, the indexing rotary component 6 includes an indexing drive assembly 61 and a rotary table. The rotary table includes a rotary disk 62, a rotary bearing 63, and an I-shaped fixing frame 64. Five through holes 62.1 are machined in a circumferential array on the rotary disk 62. The rotary disk 62 is rotatably mounted on the I-shaped fixing frame 64 via the rotary bearing 63. Five indexing components 65 are arranged in a circular array on the bottom surface of the rotary disk 62. Driven by the indexing drive assembly 61, the rotary disk 62 rotates 72 degrees each time, used to rotate the accompanying fixture 8 to different work positions. Two anti-reverse stop blocks 66 are installed at 180-degree intervals on the reverse side of the rotary disk 62. Two anti-reverse kits 67 are correspondingly installed at 180-degree intervals on the top surface of the I-shaped fixing frame 64. Through the cooperation of the anti-reverse stop blocks 66 and the anti-reverse kits 67, the rotary disk 62 is prevented from reversing.

[0034] like Figure 17 As shown, the indexing drive assembly 61 includes an indexing bracket 611, an indexing rodless cylinder 612, and an indexing drive block 613. The indexing rodless cylinder 612 is mounted on the upper surface of the indexing bracket 611, and the indexing drive block 613 is mounted on the slider of the indexing rodless cylinder 612. The indexing drive block 613 is a half-hollow cylinder, and the outer edge 613.2 of the half-hollow cylinder is chamfered.

[0035] like Figure 18 and 19As shown, the indexing assembly 65 includes an end baffle 651, a T-shaped slider 652, a drive column 653, a fall arrestor 654, a first telescopic spring 655, a frame body 656, and a second telescopic spring 657. The frame body 656 has a T-slot machined in it. The T-shaped slider 652 is movably installed in the T-slot of the frame body 656. The first telescopic spring 655 is installed between the T-shaped slider 652 and a countersunk hole on the closed side of the T-slot of the frame body 656. To prevent the T-shaped slider 652 from sliding out of the T-slot of the frame body 656, an end baffle 651 is installed on the open side of the T-slot of the frame body 656. The T-shaped slider 652 has a countersunk hole in the middle. The drive column 653 consists of two cylindrical sections, one large and one small, with the top surface of the smaller cylindrical section having rounded corners. Three large cylindrical sections are installed in the countersunk hole in the middle of the T-shaped slider 652, and a second telescopic spring 657 is installed between the drive column 653 and the countersunk hole in the middle of the T-shaped slider 652. Under the action of external force, the drive column 653 can move up and down in the countersunk hole in the middle of the T-shaped slider 652. To prevent the drive column 653 from sliding out of the countersunk hole in the middle of the T-shaped slider 652, a fall-prevention plate 654 is installed on the top surface of the T-shaped slider 652. A through hole is machined in the middle part of the fall-prevention plate 654, and the small cylindrical section of the T-shaped slider 652 passes through the through hole in the middle part of the fall-prevention plate 654. When the outer edge 613.2 of the half-hollow cylinder of the indexing drive block 613 of the indexing drive assembly 61 acts on the drive post 653 of the indexing assembly 65, the drive post 653 will be pressed into the countersunk hole in the middle of the T-shaped slider 652 due to the chamfered surface of the outer edge 613.1. When the inner edge 613.1 of the half-hollow cylinder of the indexing drive block 613 of the indexing drive assembly 61 acts on the drive post 653 of the indexing assembly 65, the drive post 653 will not be pressed into the countersunk hole in the middle of the T-shaped slider 652 because the inner edge 613.1 does not have a chamfered surface. The indexing assembly 65 moves under the thrust of the indexing drive block 613 of the indexing drive assembly 61.

[0036] like Figure 20 As shown, the anti-reverse assembly 67 includes a No. 3 telescopic spring 671, a base 672, and an anti-reverse cylinder 673. One end of the anti-reverse cylinder 673 is rounded, and a countersunk hole is machined in the middle of the base 672. The anti-reverse cylinder 673 is placed in the countersunk hole in the middle of the base 672 via the No. 3 telescopic spring 671, with the rounded end facing outwards. When the outer edge of the anti-reverse stop 66 acts on the anti-reverse cylinder 673 of the anti-reverse assembly 67, the chamfered surface of the outer edge presses the anti-reverse cylinder 673 into the countersunk hole in the middle of the base 672, allowing the anti-reverse stop 66 to slide past the anti-reverse cylinder 673. When the inner edge of the anti-reverse stop 66 acts on the anti-reverse cylinder 673 of the anti-reverse assembly 67, since the inner edge lacks a chamfered surface, the anti-reverse cylinder 673 will not be pressed into the countersunk hole in the middle of the base 672. The anti-reverse cylinder 673 prevents the movement of the anti-reverse stop 66, thereby preventing the rotary table 62 from reversing.

[0037] like Figure 21 As shown, the pressing assembly 9 includes a bracket 91, a double-rod cylinder 92, and an arc-shaped pressure plate 93. The double-rod cylinder 92 is mounted on the bracket 91, and the ends of the piston rods of the double-rod cylinder 92 are symmetrically mounted on the arc-shaped pressure plate 93. When the piston rods of the double-rod cylinder 92 extend or retract, they drive the arc-shaped pressure plate 93 to move up and down.

[0038] The working principle of an automatic wire cutter assembly device is as follows: 1. The slider of the indexing rodless cylinder 612 moves one stroke, which drives the rotary table 62 to rotate 72 degrees through the indexing drive assembly 61, thereby causing the accompanying fixtures 8 arranged on the rotary table 62 to rotate to their respective work positions. 2. The piston rod of the double-rod cylinder 92 of the pressing component 9 extends, driving the arc-shaped pressure plate 93 to move down. The arc-shaped pressure plate 93 presses the first water platform 101 of the first station 1 and the second water platform 201 of the second station 2. The first water platform 1 of the first station 1 and the second water platform 201 of the second station 2 are respectively in close contact with the upper surface of the accompanying fixture 8. 3. The piston rod of the first telescopic cylinder 103 at the first work station 1 extends and pushes the left half 71, located at the bottom of the left half storage 102, forward through the first forming pusher 104 until the left half 71 falls into the left half cavity 81 of the accompanying fixture 8 through the first forming through hole 101.1. The piston rod of the first telescopic cylinder 103 retracts and waits for the next operation.

[0039] 4. The piston rod of the second telescopic cylinder 203 at the second work station 2 extends and pushes the right half 72, which is located at the bottom of the right half storage 202, forward through the second forming pusher 203 until it falls into the right half cavity 82 of the accompanying fixture 8 through the third forming through hole 201.1. The piston rod of the second telescopic cylinder 203 retracts and waits for the next operation.

[0040] 5. At the third station 3, the piston rod of the third telescopic cylinder 323 of the gripping component 32 extends, and the third vacuum suction cup 324 adsorbs the rotating shaft 73 in the horizontal slide rail 314. The piston rod of the third telescopic cylinder 323 retracts, and the third rodless cylinder 322 actuates, moving the rotating shaft 73 adsorbed by the third vacuum suction cup 324 above the accompanying clamp 8. The piston rod of the third telescopic cylinder 323 extends again, placing the rotating shaft 73 adsorbed by the third vacuum suction cup 324 into the center hole of the left half 71 and the right half 72 of the wire cutters 7. The piston rod of the third telescopic cylinder 323 retracts again, and the third rodless cylinder 322 reverses its action, waiting for the next operation.

[0041] 6. The piston rods of the lower hydraulic cylinder 401 and the upper hydraulic cylinder 402 of the fourth station 4 extend out. The piston rod of the lower hydraulic cylinder 401 passes through the through hole 62.1 of the rotary table 62. The piston rods of the lower hydraulic cylinder 401 and the upper hydraulic cylinder 402 simultaneously squeeze the rotating shaft 73 in the center hole of the left half 71 and the right half 72 of the wire cutter 7. The rotating shaft 73 is pressed firmly into the center hole of the left half 71 and the right half 72 of the wire cutter 7. Then the piston rods of the lower hydraulic cylinder 401 and the upper hydraulic cylinder 402 retract, waiting for the next operation.

[0042] 7. The piston rod of the fifth telescopic cylinder 503 at the fifth station 5 extends, and the fifth vacuum suction cup 501 adsorbs the assembled wire cutters 7. The piston rod of the fifth telescopic cylinder 503 retracts, and the rotating arm 502 rotates under the drive of the fifth rotary cylinder 504, taking away the assembled wire cutters 7 from the accompanying fixture 8.

[0043] 8. The slider of the indexing rodless cylinder 612 moves in the opposite direction by one stroke and returns to the initial position. The piston rod of the double-rod cylinder 92 of the pressing component 9 retracts, causing the arc-shaped pressure plate 93 to move upward, releasing the pressure on the first station 1 water platform 101 and the second station 2 water platform 201. The first station 1 water platform 101 and the second station 2 water platform 201 rise and return to the initial position, waiting for the next operation.

Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
