Description

Technical Field

[0001] This invention belongs to the field of transformer structural component processing technology, specifically relating to an automatic processing system and method for wire clamps. Background Technology

[0002] Wire clamps are insulating structural components installed inside transformers to support and secure wires. They are typically made from laminated cardboard or laminated wood panels and require multiple processing steps, including planing, shearing, milling, drilling, and grinding. Because the specifications, lengths, and quantities of wire clamps required for each transformer vary depending on the design drawings, the products are diverse, produced in small batches, and exhibit extremely high specification variation.

[0003] In the existing production model, the processing of wire clamps mainly relies on manual labor and discrete single-machine operations. Before production, operators need to manually calculate the processing requirements for strips of different lengths, and then cut them into various sizes on plates of different specifications to obtain semi-finished strips (hereinafter referred to as strips). Subsequently, the strips are sent to different equipment such as drilling machines and milling machines to process the characteristic structures such as holes and slots on the wire clamps one by one, and cut them into individual wire clamps. Finally, the edges and corners of the wire clamps are manually polished. The entire process is usually divided into four to five independent processes, involving a large number of equipment, long process flow time, and because each piece of equipment has a single function, multiple pieces of equipment occupy a large area.

[0004] Furthermore, the process analysis and material calculation for machining drawings and bills of materials (BOM) all rely on manual labor, which is labor-intensive and prone to misjudgment, leading to missing parts, omissions, or machining errors. Because there are numerous types of wire clamps, frequent changes to production line tooling and machining parameters are required during production, further reducing production efficiency and making it difficult to meet the flexible production needs of multiple varieties and small batches.

It includes a conveyor frame 39, a pushing mechanism 5, a grooving saw mechanism 6, a second support beam 7, a loading drive motor 8, and a loading support beam 17. The conveyor frame 39 is a stepped frame welded from square steel and steel plates, including a frame body, an upper step surface 9, a lower step surface 10, and frame support columns 43. The frame body, upper step surface 9, and lower step surface 10 are fixedly connected into an integrated structure by five frame support columns 43 located at the rear. The pushing mechanism 5 is located at the upper step surface 9, and the grooving saw mechanism 6 is located at the lower step surface 10 (located to the right of the rightmost loading support beam 17). Several loading guard plates 11 are provided on the front end and both sides of the lower step surface 10. The loading guard plates 11 provide protection when the equipment is working. Electrical circuits are arranged in the cavity of the frame body. The control terminal adopts a motion controller. The motion controller communicates with each device through the MOdbus protocol. The host computer interacts with the control terminal. Both the host computer and the motion controller use existing products. The host computer stores the relevant parameters for strip feeding, wire clamp processing, and finished product sorting and stacking designed in the processing drawings. The motion controller automatically completes the strip feeding, wire clamp processing, and finished product unloading and stacking.

[0021] Three first support beams 12 protruding forward from the front end of the frame body are evenly spaced at one end (left end) of the lower step surface 10 near the automatic processing device 2. Three feeding support beams 17 are fixedly installed on the first support beams 12 by a pair of L-shaped feeding support seats 16.

A pair of mounting plates 19 are symmetrically arranged on the two outer sides of the front and rear ends of the feeding support beam 17. Each mounting plate 19 extends outward and protrudes from the end of the feeding support beam 17. A diamond-shaped bearing 24 is fixed to the mounting plate 19 on at least one side of the front end of each feeding support beam 17 by bolts. A first through hole is opened at the center of the pair of mounting plates 19 protruding from the front end of the feeding support beam 17. The two ends of the transmission rod 23 pass through the first through hole and the diamond-shaped bearing 24, and are rotatably connected to the pair of mounting plates 19 through the diamond-shaped bearing 24.

[0023] Both ends of the transmission rod 23 are fixedly equipped with drive pulleys, which are located between a pair of mounting plates 19.

When feeding, the right end of the strip is aligned with the positioning rod 13. The toothed belt 18 is driven to rotate by the feeding drive motor 8, which drives the strip on the toothed belt 18 to be conveyed to the second support beam 7.

[0026] A first photoelectric switch 31 is installed on the left rear end of the feeding support beam 17, which is close to the grooving saw mechanism 6, via a support component. The first photoelectric switch 31 is used to detect whether there is a strip of material passing through.

[0027] The second support beam 7 is made of aluminum profile. Second guide rails 46 are respectively installed on the frame support columns 43 at the rear ends of the three feeding support beams 17.

The piston rod of the clamping cylinder 34 is fixedly connected to the clamping plate 30.

[0030] The pressing mechanism 14 includes a pressing lifting cylinder 44 disposed on the rear side of the second support beam 7. The piston rod of the pressing lifting cylinder 44 is fixedly connected to the pressing slide plate 36. A pressing telescopic cylinder 37 is mounted on the pressing slide plate 36, with the piston rod of the pressing telescopic cylinder 37 facing horizontally forward. A pressing roller 38 is mounted on the piston rod of the pressing telescopic cylinder 37. Through the coordinated operation of the pressing lifting cylinder 44 and the pressing telescopic cylinder 37, the pressing roller 38 can move horizontally and vertically back and forth. The idler roller 26 is mounted horizontally on the idler roller frame 60. The idler roller 26 is perpendicular to the length direction of the second support beam 7, and the length of the idler roller 26 is adapted to the width of the largest specification strip. The pressing roller 38 cooperates with the idler roller 26 to press the strip from the vertical direction. In the first embodiment of the present invention, a total of four support rollers 26 and one pressure roller 38 are provided. One support roller 26 is provided on each clamping mechanism 15 to support the strip material from below, but only one pressure roller 38 is provided near the grooving saw mechanism 6, which can save costs while meeting the needs of sawing applications.

[0031] The side clamping roller 27 is higher than the side support roller 26, the side limiting roller 25 is higher than the side support roller 26, and the height of the side limiting roller 25 is adapted to the height of the largest specification strip. The center line of the side clamping roller 27 is parallel to the center line of the side limiting roller 25, the center line of the side support roller 26 is parallel to the center line of the pressure roller 38, and the length of the first guide rail 28 and the stroke of the clamping cylinder 34 are both greater than the length of the side support roller 26.

[0032] The grooving saw mechanism 6 is used to process a groove at the right end of the strip material, facilitating the material clamping assembly 42 to clamp the material through the groove. It includes a grooving saw 47 capable of horizontal and vertical movement. A grooving saw mounting plate 48 is fixedly mounted on the right side of the rightmost first support beam 12.

The grooving saw 47 is fixedly mounted on the right side of the grooving saw lifting plate 50. Through the coordinated operation of the grooving translation cylinder and the grooving lifting cylinder, the grooving saw 47 can move horizontally and vertically.

[0033] The pushing mechanism 5 is used to push the slotted strip material to the processing station in the automatic processing device 2. It includes a pushing rod 41 that can move horizontally and vertically, and a pushing clamp assembly 42 installed at the left end of the pushing rod 41. The mechanism and method for moving the pushing rod 41 are existing technologies. For example, it can be achieved by the following scheme: a pushing horizontal motor 61 and a pushing lifting back plate 66 are installed on the pushing support 69. A pair of pushing guide rails 64 and a pushing rack 63 are set on the upper step surface 9. The pushing support 69 is slidably connected to the pushing guide rails 64 through a pushing slide plate 65 and a pushing slider 62. A pushing lifting frame 67 and a pushing lifting motor 68 are installed on the pushing lifting back plate 66. The pushing rod 41 is installed horizontally at the lower part of the pushing lifting frame 67. Through the coordinated operation of the pushing horizontal motor 61 and the pushing lifting motor 68, the pushing rod 41 is driven to move horizontally and vertically.

[0034] The pusher clamp assembly 42 includes a thin cylinder 52 installed at the left end of the pusher rod 41. The left side of the thin cylinder 52 is fixedly connected to a chuck support 54. The chuck support 54 includes a chuck support body with a flat plate structure, and protrusions 53 and upright plates 58 located at both ends of the chuck support body. The left end face of the chuck support 54 behind the upright plate 58 is provided with an integrally formed lower jaw 59 extending to the left. The protrusions 53 are perpendicular to the piston rod of the thin cylinder 52, and the upright plates 58 are parallel to the piston rod of the thin cylinder 52. The piston rod of the thin cylinder 52 passes through the protrusion 53 and is fixedly connected to the chuck connecting block 55. The right end of the chuck connecting plate 56 is rotatably connected to the chuck connecting block 55. The left end of the chuck connecting plate 56 is rotatably connected to the right end of the chuck connecting plate 57. The middle part of the chuck connecting plate 57 is rotatably connected to the upright plate 58. The left end of the chuck connecting plate 57 is an upper jaw 51 protruding from the left end face of the upright plate 58 in an integral structure. The position of the upper jaw 51 is adapted to the lower jaw 59.

[0035] like Figure 8-16As shown, the automatic processing device 2 is used for multi-face composite processing and cutting of strip materials with features such as holes, grooves, fillets, and threaded holes. It completes all feature processing on multiple sides of the workpiece in a single clamping operation. The device includes a protective cover 99, a main frame, a first processing spindle assembly 80, a second processing spindle assembly 73, a tool magazine assembly 74, a cutting saw assembly 102, and processing clamping mechanisms, cutting clamping mechanisms, and unloading mechanisms 84. The processing clamping mechanisms are used to clamp and position the strip materials entering the automatic processing device 2 during processing. The processing clamping mechanisms include a first clamping mechanism 76 and a second clamping mechanism 77. The cutting clamping mechanisms are used to clamp and position the strip materials during cutting. The cutting clamping mechanisms include a cutting clamping mechanism 106 and a cutting pressing mechanism 107.

[0036] The protective cover 99 completely encloses the outside of the main frame. A loading inlet is located on the side of the protective cover 99 that connects with the loading platform 1, and a unloading outlet 151 is located on the side of the protective cover 99 that connects with the unloading platform 3. A transparent acrylic observation window is provided on the front face of the protective cover 99 in the area corresponding to the processed strip material. A control panel is located on the rightmost panel of the front side of the protective cover 99, allowing control of the processing equipment.

[0037] The main frame is a welded frame structure of square steel tubes, including a base 82. The base 82 is an irregularly shaped planar frame welded from rectangular square steel tubes. The lower end of the base 82 is fixed to the foundation by anchor bolts. Several connecting plates 78 are welded to the upper end of the base 82 for fixing and installing the reinforcing support frame 85, the intermediate support frame 81, and the processing clamping mechanism. The intermediate support frame 81 is a frame welded from four columns, a connecting beam connecting the tops of the four columns, a connecting plate 78 connecting the bottoms of the four columns, and a reinforcing beam in the middle. The four columns are spaced back and forth along the same horizontal line in the width (front and back) direction of the base 82 and are of the same height. The intermediate support frame 81 divides the internal space of the main frame into two areas: the right processing area 71 and the left cutting area 70.

[0038] In the right processing area 71, a first processing spindle assembly 80 is installed in front of the right side of the intermediate support frame 81, and a second processing spindle assembly 73 is installed behind the right side. These are used for multi-faceted composite processing of strip materials, including hole and slot milling, edge rounding, and threaded hole machining. In the left cutting area 70, a cutting saw assembly 102 is installed in front of the left side of the intermediate support frame 81. This assembly automatically cuts the processed strip materials into single finished products according to parameters. Corresponding to the first processing spindle assembly 80, the second processing spindle assembly 73, and the cutting saw assembly 102, inverted L-shaped reinforcing support frames 85 are respectively installed. The upper end of the reinforcing support frame 85 is fixedly connected to the intermediate support frame 81, and the lower end of the reinforcing support frame 85 is fixedly connected to the connecting plate 78 located outside the right processing area 71 and the left cutting area 70. The reinforcing support frame 85 is used to enhance the overall rigidity of the main frame in the direction of processing force.

[0039] The first machining spindle assembly 80 is mounted on two columns in front of the intermediate support frame 81. It is a dual-head variable-position spindle assembly used for milling holes and slots, as well as rounding edges and corners on the top and side surfaces of the workpiece. This assembly includes an X-axis transverse feed mechanism, a Y-axis lifting mechanism, a Z-axis longitudinal feed mechanism, a spindle rotation mechanism, and a dual-head spindle unit (including the first machining spindle and the dual cutters). The structure of this part is prior art, and its working principle is briefly described below: The Y-axis lifting mechanism is used to drive the first machining spindle to move vertically, accommodating the machining of workpieces of different thicknesses and the switching of tools at different heights. The Y-axis lifting mechanism includes a Y-axis slide plate, a Y-axis guide rail, a Y-axis slider, a Y-axis ball screw assembly, and a Y-axis servo motor. The Y-axis guide rail is laid vertically on the right end face of the two columns in front of the right side of the intermediate support frame 81. The left end face of the Y-axis slide plate is slidably connected to the Y-axis guide rail via the Y-axis slider. The right end face of the Y-axis slide plate supports the Z-axis longitudinal feed mechanism. The lead screw of the Y-axis ball screw assembly is installed vertically on the upper and lower reinforcing beams between the two columns. The nut is fixed to the left end face of the Y-axis slide plate, and the upper end of the lead screw is connected to the output shaft of the Y-axis servo motor via a coupling. The Y-axis servo motor is mounted on the upper reinforcing beam, driving the lead screw of the Y-axis ball screw assembly to rotate and thus causing the Y-axis slide plate to move vertically.

[0040] The Z-axis longitudinal feed mechanism is used to drive the first machining spindle to feed along the width direction of the workpiece, realizing the adjustment of the position of the first machining spindle relative to the side of the workpiece and the cutting feed. The Z-axis longitudinal feed mechanism includes a Z-axis carriage, a Z-axis guide rail, a Z-axis slider, a Z-axis ball screw pair, and a Z-axis servo motor. The Z-axis guide rail is laid on the right end face of the Y-axis slide along the width direction (longitudinal direction) of the workpiece, and the left end face of the Z-axis carriage is engaged with the Z-axis guide rail through the Z-axis slider. The lead screw of the Z-axis ball screw pair is installed longitudinally on the right end face of the Y-axis slide and supported by a fixed seat. The nut is fixedly connected to the left end face of the Z-axis carriage, and one end of the lead screw is connected to the output shaft of the Z-axis servo motor through a coupling. The Z-axis servo motor drives the lead screw of the Z-axis ball screw pair to rotate, causing the Z-axis carriage to reciprocate along the width direction of the workpiece.

[0041] The X-axis transverse feed mechanism is used to drive the first machining spindle to feed laterally along the length of the strip. The X-axis transverse feed mechanism includes an X-axis slide plate, an X-axis guide rail, an X-axis slider, an X-axis ball screw pair, and an X-axis servo motor. The X-axis guide rail is laid laterally on the rear end face of the Z-axis carriage, and the front end face of the X-axis slide plate engages with the X-axis guide rail via the X-axis slider. The lead screw of the X-axis ball screw pair is mounted laterally on the rear end face of the Z-axis carriage, and the nut is fixedly connected to the front end face of the X-axis slide plate. One end of the lead screw is connected to the output shaft of the X-axis servo motor via a coupling. The X-axis servo motor drives the lead screw of the X-axis ball screw pair to rotate, causing the X-axis slide plate to reciprocate along the length of the workpiece, thus achieving transverse feed during the machining process.

[0042] A spindle rotation mechanism is mounted on the rear end face of the X-axis slide plate and is used to drive the dual-head spindle unit to rotate around a horizontal line, enabling the switching of the machining surface and rapid tool repositioning at both ends. The spindle rotation mechanism includes a rotary base, a rotary support base, a pulley assembly, and a rotary servo motor. The rotary support base is mounted on the rear end face of the X-axis slide plate, and the rotary base is mounted on the right end face of the rotary support base, allowing it to rotate circumferentially around a horizontal line parallel to the workpiece length. The driven pulley of the pulley assembly is coaxially fixed to the rotary base, and the driven pulley is connected to the driving pulley via a belt. The driving pulley is connected to the output shaft of the rotary servo motor. The rotary servo motor drives the driving pulley to rotate, which in turn drives the rotary base to rotate around a horizontal line via the belt, thereby switching the orientation and machining surface of the tools at both ends of the dual-head spindle unit.

[0043] The second machining spindle assembly 73 is mounted on two columns behind the intermediate support frame 81. It is a single-head tool-changing spindle assembly used for finishing workpiece features such as holes, grooves, fillets, and threaded holes. The second machining spindle assembly 73 includes a second X-axis transverse feed mechanism, a second Y-axis lifting mechanism, a second Z-axis longitudinal feed mechanism, a second spindle rotation mechanism, a single-head spindle unit (including the second machining spindle and replaceable single-head tools), and a tool magazine assembly 74. Since the workpiece passes through the center of the intermediate support frame 81, the first machining spindle assembly 80 and the second machining spindle assembly 73 are respectively positioned on the front and rear sides of the workpiece. The components of the second machining spindle assembly 73 have the same structure as those of the first machining spindle assembly 80, but some components are installed in opposite directions, and the two are symmetrically arranged. The single-head spindle unit is fixed to the rotary seat of the second spindle rotation mechanism, and the axis of the second machining spindle is perpendicular to the rotation axis of the rotary seat. Unlike the dual-head structure of the first machining spindle assembly 80, the single-head spindle unit only has a tool interface at the front end, which, together with the tool magazine assembly 74, enables quick replacement of different tools.

[0044] The tool magazine assembly 74 is mounted on the tool magazine support beam 72. The tool magazine support beam 72 is positioned along the front-to-back direction, with both ends welded to the lower end face of the top beam of the reinforcing support frame 85. The tool magazine assembly 74 includes a tool magazine guide rail, a tool magazine slider, a tool magazine cylinder, a geared motor, and the tool magazine itself; these are existing technologies and will not be described in detail. The tool magazine includes a tool disc and a tool magazine cover. A geared motor is located at the center of the upper end of the tool disc, enabling rotation. An opening is provided on the left side of the tool magazine cover for easy docking and tool changing with the second machining spindle assembly 73. The tool magazine assembly 74 can move back and forth along the tool magazine support beam 72. When the second machining spindle assembly 73 needs a tool change, the tool magazine cylinder drives the tool magazine to move towards the second machining spindle assembly 73, reaching the designated tool changing position. The tool change is performed according to the programmed actions, and after the tool change, the tool magazine cylinder drives the tool magazine back to its initial position.

[0045] The first clamping mechanism 76 is located below the feeding inlet, and the second clamping mechanism 77 is located on the intermediate support frame 81. The second clamping mechanism 77 is located between the first machining spindle assembly 80 and the second machining spindle assembly 73.

The support rollers 98 are parallel to and corresponding to the idler rollers 26, thereby facilitating the connection and conveying of strip materials. The first clamping mechanism clamps the strip material from front to back. It includes a pair of bearings 164 at the top left and right ends of the mounting frame 88 and a pair of bearings 92 that move back and forth. The third guide rail 95 is set on the upper surface of the support frame 94 along its length. The lower end of the movable positioning plate 97 is provided with a third slider 96 that cooperates with the third guide rail 95. A pair of clamping posts 93 are provided on the left and right sides of the upper end of the movable positioning plate 97. Each clamping post 93 is equipped with a bearing 92 at its top. The right side of the mounting frame 88 is provided with a clamping cylinder 90 that drives the movable positioning plate 97 to move back and forth. The piston rod of the clamping cylinder 90 is connected to the movable positioning plate 97. The first clamping mechanism clamps the strip material vertically. It includes a pressure plate 87 that moves vertically behind the mounting frame 88. The pressure plate 87 is higher than the upper surface of the mounting frame 88. Three pressure rollers 86 are spaced apart along the left and right direction on the front surface of the pressure plate 87. The pressure rollers 86 are parallel to the support rollers 98. A clamping cylinder connecting plate 89 is located behind the pressure plate 87. A sixth slider is located on the side of the clamping cylinder connecting plate 89 facing the mounting frame 88. A sixth guide rail that cooperates with the sixth slider is located on the side of the mounting frame 88 opposite to the clamping cylinder connecting plate 89. A clamping cylinder 91 that drives the clamping cylinder connecting plate 89 to move vertically is located on the right side of the mounting frame 88. The piston rod of the clamping cylinder 91 is connected to the clamping cylinder connecting plate 89.

[0047] The second clamping mechanism 77 includes a second clamping mechanism and a second pressing mechanism. The second clamping mechanism and the second pressing mechanism are basically the same in structure as the first clamping mechanism and the first pressing mechanism. The main difference is that they are set according to the structure of the intermediate support frame 81 to ensure that the second support roller 128 is flush with the first support roller 98. The second clamping mechanism mainly includes the horizontally installed second support roller 128 and the fifth guide rail 125, as well as the fifth slider 124 which is slidably connected to the fifth guide rail 125.

The cutting and clamping cylinder 110 is inclined towards the positioning plate 114 to save space. The seventh guide rail is mounted on the saw support 112, and the seventh slider is slidably connected to the seventh guide rail. The seventh slider is located below the clamping slide plate 111. The piston rod of the cutting and clamping cylinder 110 is connected to the clamping slide plate 111. The cutting and clamping cylinder 110 drives the clamping slide plate 111 to move towards the saw support base plate 113 and the positioning plate 114, thereby clamping the strip to be sawed.

[0050] The cutting and pressing mechanism 107 includes a fixed support plate 117, a cutting and pressing cylinder 108, a pressing upright plate 115, a fourth guide rail 116, and a fourth slider 118, which realizes the pressing of the upper end face of the strip to be sawed, ensuring stability during sawing.

The rotating shaft of the feeding motor 142 is perpendicular to the upper end face of the feeding support beam 139. The rotating shaft of the feeding motor 142 passes through the feeding motor support seat 141 and is connected to the feeding gear. A feeding rack 140, which meshes with a feeding gear, is provided on the upper surface of the feeding support beam 139. The feeding rack 140 is arranged along the length of the feeding support beam 139. Driven by the feeding motor 142, the feeding positioning plate 147 can be moved to the feeding conveying mechanism 152.

[0055] A horizontal triangular bracket 136 is bolted to the upper end of the front face of the unloading positioning plate 147. The hypotenuse of the triangular bracket 136 forms a 45° angle with its two straight sides. One straight side of the triangular bracket 136 is fixedly connected to the unloading positioning plate 147, and the hypotenuse of the triangular bracket 136 is fixedly connected to the lower top plate 135. The lower top plate 135 has an irregular shape, and an unloading clamping cylinder 122 parallel to the hypotenuse of the triangular bracket 136 is fixedly installed at the lower part of the lower top plate 135. A tenth slider is fixedly installed on the lower surface of the lower top plate 135. The unloading clamping plate 150 is installed below the lower top plate 135.

The material feeding and pressing cylinder 143 is installed vertically on the material feeding and pressing cylinder support 144. The material feeding and pressing vertical plate 145 is slidably connected to the material feeding and pressing cylinder support 144 through a slide rail-slider. The material feeding and pressing vertical plate 145 is located in front of the material feeding positioning vertical plate 147. The material feeding and pressing vertical plate 145 can move up and down under the drive of the material feeding and pressing cylinder 143 to limit the workpiece in the vertical direction.

[0056] It should be noted that the unloading positioning plate 147 is located behind the unloading positioning base plate 148, and the lower end face of the unloading positioning plate 147 is flush with the upper end face of the unloading positioning base plate 148. The lower top plate 135 is located in front of the unloading positioning base plate 148, and the lower end face of the lower top plate 135 is higher than the upper end face of the unloading positioning base plate 148. The distance between the lower end face of the lower top plate 135 and the upper end face of the unloading positioning base plate 148 is greater than the thickness of the unloading clamping plate 150. That is, there is a gap between the lower end face of the unloading clamping plate 150 and the upper end face of the unloading positioning base plate 148, so that the lower end face of the unloading clamping plate 150 is slightly higher than the upper end face of the unloading positioning base plate 148 to prevent friction between the two. The workpiece is clamped by the cooperation of the short side of the unloading clamping plate 150 and the unloading positioning plate 147. Then, with the cooperation of the unloading gear and the unloading rack 140, the cut workpiece is conveyed to the unloading conveying mechanism 152. The angle design at this point can effectively save space, avoid interference between the unloading clamping cylinder 122 and the frame, and facilitate the extension of the unloading clamping cylinder 122.

[0057] like Figure 16 , 17As shown, the unloading platform 3 includes a conveyor support frame 161 and an unloading conveying mechanism 152 mounted on the conveyor support frame 161. The unloading conveying mechanism 152 is located at the unloading outlet 151 and is parallel to the unloading support beam 139. The height of the conveyor support frame 161 is slightly lower than the height of the support roller 137. Unloading conveyor belts 163 are mounted on the upper left and right ends of the conveyor support frame 161 through the support of a drive shaft and a driven shaft. The drive shaft is connected to a conveyor motor 160, and both the drive shaft and the conveyor motor 160 are located at the left end of the conveyor support frame 161. A positioning strip 162, higher than the upper surface of the unloading conveyor belt 163, is installed on the rear side of the conveyor support frame 161. The positioning strip 162 is set along the length of the conveyor support frame 161, and the length of the positioning strip 162 is greater than 2 / 3 of the length of the conveyor support frame 161. Several pusher cylinders 155 are evenly distributed and fixedly installed on the front side of the conveyor support frame 161 along its length. The pusher cylinders 155 are fixedly mounted on the conveyor support frame 161 by pusher cylinder support plates 154. A flange linear bearing 157 is also installed on the pusher cylinder support plate 154 on one side of the pusher cylinder 155. The piston rod of the pusher cylinder 155 faces the positioning bar 162 and is mounted on a pusher plate 158. A guide rod 156 parallel to the piston rod of the pusher cylinder 155 is provided on the pusher plate 158. The guide rod 156 cooperates with the flange linear bearing 157 and serves as a limiting and guiding function when the pusher plate 158 moves. A front stop bar 159 perpendicular to the positioning bar 162 is provided at the left end of the conveyor support frame 161. A second photoelectric switch 153 is provided on the front side of the conveyor support frame 161 on the right side of the pusher cylinder support plate 154. The second photoelectric switch 153 is used to identify whether the workpiece has reached the unloading gripping position. After the processed workpiece arrives at the unloading position, the pusher cylinder 155 pushes the workpiece to the designated position, and the transport robot 4 on the front side of the conveyor support frame 161 moves to transport, classify and stack the workpiece.

[0058] The actuation force of each cylinder is adaptive to strips and workpieces of various specifications, until the strips and workpieces are clamped.

[0059] Example 2

[0060] Embodiment 2 of the present invention provides an automatic processing method for wire clamps, using the automatic processing system for wire clamps described in Embodiment 1. The initial states of each component are as follows: The upper surface of the second support beam 7 is initially lower than the upper surface of the feeding support beam 17, and the upper surfaces of the idler roller 26 and the side clamping roller 27 are also lower than the upper surface of the feeding support beam 17, so as not to hinder the smooth passage of the strip. The initial state of the side clamping roller 27 is that the piston rod of the clamping cylinder 34 is fully extended, so that the distance between the side clamping roller 27 and the side limiting roller 25 is greater than the thickness of the strip.

[0061] The first photoelectric switch 31 is installed at the same level as the initial position of the side clamping roller 27. The initial state of the pressing telescopic cylinder 37 is the retracted state, and the initial state of the pressing lifting cylinder 44 is the extended state.

[0062] When the strip enters the automatic processing device 2, the processing position of each tool is fixed. What needs to be adjusted is the positioning in the length direction of the strip. This positioning can be achieved by the servo control of the pushing mechanism 5. They are all coordinate systems.

[0063] The steps for automatically processing wire clamps using an automated wire clamp processing system are as follows: S1. Place the strip to be processed onto the toothed belt 18, with the right end of the strip aligned with the positioning rod 13. Start the feeding drive motor 8, which drives the toothed belt 18 to rotate, thus conveying the strip to the rear end of the feeding support beam 17.

[0064] When the strip passes the first photoelectric switch 31, the first photoelectric switch 31 detects the presence of material and transmits a signal to the control terminal. The control terminal controls the feeding drive motor 8 to start decelerating. After the entire strip has passed, the first photoelectric switch 31 detects the absence of material and transmits a signal to the control terminal, which then controls the feeding drive motor 8 to stop. At this time, the strip reaches the rear of the side clamping roller 27. The control terminal controls the lifting cylinder 40 to lift, driving the support roller 26 to rise and lift the strip. The lifting cylinder 40 stops after reaching the set height. The control terminal controls the clamping cylinder 34 to retract, pulling the side clamping roller 27 backward, gradually reducing the distance between the side clamping roller 27 and the side limiting roller 25 until the strip is clamped. The control terminal controls the pressing telescopic cylinder 37 to extend forward a certain distance according to the strip specification information. After the pressing roller 38 is in place, the control terminal controls the pressing lifting cylinder 44 to descend, and the pressing roller 38 presses down on the strip from above, completing the fixing of the strip.

[0065] S2. After the strip material is fixed, it is sawed and clamped by the grippers. The host computer sends the strip material specification information (width, height) to the control terminal. The control terminal controls the grooving lifting cylinder to drive the grooving saw lifting plate 50 to rise and fall. The initial height of the grooving saw 47 is a fixed value. The host computer calculates the lifting height of the grooving saw 47 based on the strip material height information and controls the piston rod stroke of the grooving lifting cylinder according to the lifting height. After the height of the grooving saw 47 is adjusted to the correct position, the grooving translation cylinder pushes the grooving saw 47 to move back and forth, sawing a groove on the right end of the strip material.

[0066] S3. The pusher lifting motor 68 starts and adjusts the height of the pusher rod 41 and the lower gripper 59 so that the lower gripper 59 aligns with the slot of the strip. After the lower gripper 59 reaches the vertical position, the pusher lifting motor 68 stops, and the pusher horizontal motor 61 starts, causing the lower gripper 59 to move to the left and extend into the slot. After the lower gripper 59 reaches the horizontal position, the pusher horizontal motor 61 stops, and the control terminal controls the piston rod of the thin cylinder 52 to extend to the left, causing the left end of the upper gripper 51 to rotate downward and clamp the upper surface of the strip. The clamping position of the upper gripper 51 is at the middle position in the width direction of the strip. After the upper gripper 51 reaches the position, the thin cylinder 52 stops. The right end of the strip is positioned by the positioning rod 13 during feeding, and the stroke of the pusher horizontal motor 61 is determined accordingly.

[0067] After the upper jaw 51 and lower jaw 59 clamp the end of the strip, the control terminal controls the pressing telescopic cylinder 37 and the pressing lifting cylinder 44 to return to their initial state, so as not to hinder the subsequent leftward advancement of the strip.

[0068] S4. The control terminal starts the horizontal pushing motor 61 to push the strip material towards the automatic processing device 2.

[0069] After the strip enters the automatic processing device 2, the horizontal pushing motor 61 stops when it reaches the processing position. The control terminal controls the processing clamping mechanism to clamp and fix the strip. Then, the control terminal sends a signal to control the first processing spindle assembly 80 and the second processing spindle assembly 73 to process the strip according to the set program.

[0070] After processing is completed, the control terminal controls the processing clamping mechanism to release the strip and reset it. The control terminal controls the pusher horizontal motor 61 to start, pushing the strip towards the cutting saw assembly 102. After reaching the position, the pusher horizontal motor 61 stops. The control terminal controls the cutting clamping mechanism to clamp the processed strip from four sides, controls the unloading clamping mechanism to clamp the strip, controls the unloading limit mechanism to limit the strip, and controls the cutting saw assembly 102 to saw the strip according to the program. After the sawing is completed, the control terminal controls the cutting clamping mechanism to release the strip and reset it.

[0071] S5. At this time, the unloading clamping mechanism clamps the sawn workpiece from the front and back directions, and the unloading limiting mechanism limits the workpiece from the vertical direction. The control terminal controls the unloading motor 142 (servo motor) to start, driving the unloading clamping mechanism to move to the lower material table 3. When it reaches the set position, the unloading motor 142 stops, and the control terminal controls the unloading clamping mechanism to release the workpiece, so that the workpiece falls onto the unloading conveying mechanism 152. At the same time, the control terminal controls the conveying motor 160 to start, and the control terminal controls the unloading clamping mechanism to reset back to the initial position, and controls the unloading pressure plate 145 to reset, waiting for the next unloading command.

[0072] S6. The conveyor motor 160 conveys the workpiece to the material feeding area via the unloading conveyor belt 163. When the second photoelectric switch 153 detects a material signal for 5 seconds (set according to the conveying speed to ensure that the finished workpiece can contact the front stop bar 159), the unloading conveyor belt 163 stops. At the same time, the control terminal controls the pusher cylinder 155 to move and push the workpiece towards the positioning bar 162. After reaching a certain clamping force, the pusher cylinder 155 resets. The control terminal controls the handling robot 4 to move and grab the finished workpiece according to the program settings.

[0073] After the handling robot 4 transports and stacks the finished workpiece, the second photoelectric switch 153 cannot detect the finished workpiece and transmits the signal to the control terminal. The control terminal controls the unloading mechanism 84 to continue to convey the finished workpiece to the unloading conveyor 152 after the workpiece is cut off.

[0074] Note: If excess material is generated during the final processing of the strip, the thin cylinder 52 will be controlled to retract to the right when the push rod 41 reaches the final position, causing the upper gripper 51 to open. The excess material will fall onto the chip conveyor belt 83 and be conveyed to the collection box at the rear.
