Description

Technical Field

[0002] The connecting rod is a mechanical component used for transmission, mainly used in engines, compressors and other devices. The connecting rod mainly includes a rod body in the middle and connectors at both ends of the rod body. When producing and processing connecting rods, the rod body of the connecting rod needs to be turned, but for some connecting rods used in large transmission equipment, such as large diesel engines, the connecting rods used are large in size and are not suitable for ordinary lathe processing, so they need to be processed using a special processing lathe.

[0003] The flying cutter lathe is a high-precision and high-efficiency cutting equipment, including a machine tool body and a rotary tool holder. The rotary tool holder is arranged at the upper end of the machine tool body, and the machine tool body is equipped with a driving device for driving the rotary tool holder to move along three axes. The rotary cutter disc is annular, and a cutter head for cutting parts is arranged on the inner side. When processing the connecting rod body by the flying cutter lathe, the connecting rod needs to be lifted by a handling device so that the connecting rod passes through the middle of the rotary tool holder. After positioning the connecting rod, the rotary tool holder drives the cutter head to cut the connecting rod.

[0004] Regarding the above-mentioned related technologies, when placing the connecting rod, since the diameter of the connecting head at the end of the connecting rod is large, the connecting rod needs to be clamped and positioned before processing. However, since the ends of some connecting rods are not standard circles or regular polygons, it is not easy to use the common V-shaped support structure for positioning, and it is inconvenient to process the connecting rod at this time. Summary of the invention

[0005] In order to improve the convenience in processing connecting rods, the present application provides a device and a method for using a flying cutter lathe to process connecting rods.

[0006] In the first aspect, the present application provides a device for machining connecting rods on a flying cutter lathe, which adopts the following technical solution:

Under the support of the support seat, the two hydraulic cylinders push the support plate to rotate. At this time, the two support plates cooperate to limit the raw material. The support platform is driven to move vertically by the driving member, so that the two support platforms cooperate to drive the connecting rod to move vertically, so that the center hole of the raw material is opposite to the top. Move the top so that the top is inserted into the center hole. Under the positioning action of the fixed cover, the two tops cooperate to fix the connecting rod. When the end of the connecting rod is irregular, the two support plates cooperate to limit the two sides of the connecting rod, thereby facilitating the fixing of the connecting rod, which is conducive to improving the convenience of processing the connecting rod.

[0009] Optionally, two guide plates are provided on one side of the support base close to the support platform, and the two guide plates are symmetrically arranged in the horizontal direction with the top as the center, and the support base is provided with a moving motor for driving the two guide plates to move closer to or away from each other.

[0010] By adopting the above technical solution, when placing the connecting rod on the support platform, the end of the connecting rod raw material is passed through the two guide plates, and the two guide plates cooperate to limit the raw material so that the center hole of the connecting rod is located directly above or below the top, which is conducive to reducing the probability of deviation between the center hole and the top. The two guide plates are driven closer or farther away from each other by the moving motor, thereby facilitating the adjustment of the distance between the two guide plates, so that the two guide plates are suitable for connecting rods of different sizes.

Before moving the top to the center hole, by moving the positioning rod, the positioning rod drives the tapered part to approach the center hole. When the tapered part is coaxial with the center hole, it is more convenient to move the positioning rod when moving the top, which is conducive to reducing the time spent on repeatedly adjusting the top.

When the elastic member 1 is in a stretched state, it has a tendency to drive the sliding rod to approach the positioning rod.

[0014] By adopting the above technical solution, under the limiting effect of the slide groove, the moving rod drives the push rod to move when it moves, so that the push rod drives the swing rod to flip. In the initial state, the swing rod is located in the slide groove. At this time, all the positioning plates are located in the through groove, and the elastic member 1 is in a compressed state. When the conical portion is away from the top, the swing rod is driven out of the slide groove by the moving rod and the push rod, so that the swing rod is in a state perpendicular to the positioning rod. When the swing rod swings, the elastic member 1 gradually stretches. When the swing rod is vertical, the elastic member 1 is in a stretched state. At this time, the slide rod moves along the through groove toward the positioning rod. When the slide rod moves, it drives the positioning rod to rotate, so that the positioning plate is perpendicular to the swing rod. When placing the connecting rod raw material, the connecting rod is guided by the positioning plate, so as to reduce the probability of material deflection when placing the connecting rod raw material.

[0016] By adopting the above technical solution, in the initial state, the semi-ring frame is located at the upper end of the arc seat, the moving assembly drives the arc seat and the semi-ring frame to move synchronously, the installation groove 1 and the installation groove 2 cooperate to limit all the arc blocks, and when the rotating part is working, all the arc blocks move along the installation groove 1 and the installation groove 2, and the arc block moves to drive the turning block to move, and then the connecting rod raw material is turned by the turning block. When the end of the connecting rod raw material is large, all the arc blocks are separated from each other by splitting the semi-ring frame and the arc seat. At this time, the rod body of the connecting rod raw material is placed above the arc seat, and the semi-ring frame and the arc block are installed so that the connecting rod raw material is located between all the arc blocks, so that it is convenient to process the connecting rod raw material when the diameter of the connecting rod end is not easy to pass through all the annular cutter discs.

[0017] Optionally, a semi-ring block 1 is provided on one side of the arc seat, and the semi-ring block 1 is coaxially arranged with the arc seat and is slidably connected to the arc seat around the axial direction. The semi-ring frame is provided with a semi-ring block 2 that is identical to the semi-ring block 1. The arc seat is fixedly connected to a driving motor, and a moving gear is coaxially fixed to the output shaft of the driving motor. Both the semi-ring block 1 and the semi-ring block 2 are fixedly connected to a plurality of driving tooth blocks along the circumferential direction, and the moving gear is meshed with all the driving tooth blocks in sequence.

[0018] By adopting the above technical solution, when the driving motor drives the moving gear to rotate, the moving gear drives the semi-ring block 1 and the semi-ring block 2 to rotate around their own axes through meshing with the driving gear block. When the arc seat cooperates with the semi-ring frame, the joint between the semi-ring block 1 and the semi-ring block 2 is in a vertical state.

[0020] By adopting the above technical solution, the locking bolt locks and positions the upper connecting block and the lower connecting block, so that the arc seat and the semi-ring seat are in a coaxial state. When the upper connecting block conflicts with the lower connecting block, the moving block contacts the inclined surface under the action of the lower connecting block, and pushes the guide block to move through the inclined surface. When the guide block moves, it drives the plug block to move to a position away from the arc block, and at this time, the elastic member 2 is in a compressed state. When the semi-ring frame and the arc seat are separated, the positions of the semi-ring block 1 and the semi-ring block 2 are adjusted so that any slot is directly opposite to the plug block. When the upper connecting block is separated from the lower connecting block, the elastic member 2 pushes the plug block to move toward the slot. When the plug block is inserted in the slot, the semi-ring block 1 or the semi-ring block 2 connected to the semi-ring frame is limited to reduce the probability of the semi-ring block 1 or the semi-ring block 2 falling.

[0021] In a second aspect, the present application provides a method for using a device for machining a connecting rod on a flying cutter lathe, which adopts the following technical solution:

[0022] Method for using the device for machining connecting rods on a flying cutter lathe.

[0023] The following steps are involved:

[0024] Process both ends of the connecting rod raw material to make the end surface of the raw material flat, measure the center line of the connecting rod blank, and drill a center hole on the end surface;

[0025] The raw material is moved by the lifting equipment so that one end of the raw material passes through the annular cutter disc, and the two ends of the raw material are placed on the corresponding support platforms respectively. At this time, the two hydraulic cylinders drive the support plates to approach each other, so that the two support plates cooperate to limit the raw material;

[0026] The supporting platform is driven to move vertically by the driving member so that the center hole is aligned with the top.

[0027] Move the top center so that it is inserted into the center hole. At this time, the support seat limits the top center through the fixed rod, so that the two sets of top centers cooperate to limit the raw material.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. Machine the center holes at both ends of the connecting rod, pass the connecting rod through the annular cutter disc, and place the end of the connecting rod on the upper end of the support platform. Under the support of the support seat, the two hydraulic cylinders push the support plate to rotate. At this time, the two support plates cooperate to limit the raw material. The support platform is driven to move vertically by the driving member, so that the two support platforms cooperate to drive the connecting rod to move vertically, so that the center hole of the raw material is opposite to the top. Move the top so that the top is inserted into the center hole. Under the positioning action of the fixed cover, the two tops cooperate to fix the connecting rod. When the end of the connecting rod is irregular, the two support plates cooperate to limit the two sides of the connecting rod, which makes it easier to fix the connecting rod, which is conducive to improving the convenience of processing the connecting rod;

[0030] 2. Under the guidance of the threaded hole, when the threaded column is rotated, the threaded column drives the top to move along the axis. Before moving the top to the center hole, the positioning rod is moved so that the positioning rod drives the tapered part to approach the center hole. When the tapered part is coaxial with the center hole, it is more convenient to move the positioning rod when moving the top, which helps to reduce the time spent on repeatedly adjusting the top.

In the initial state, the swing rod is located in the chute. At this time, all the positioning plates are located in the through slot, and the elastic member 1 is in a compressed state. When the conical portion is away from the top, the swing rod is driven out of the chute by the moving rod and the push rod, so that the swing rod is in a state perpendicular to the positioning rod. When the swing rod swings, the elastic member 1 gradually stretches. When the swing rod is vertical, the elastic member 1 is in a stretched state. At this time, the slide bar moves along the through slot toward the positioning rod. When the slide bar moves, it drives the positioning rod to rotate, so that the positioning plate is perpendicular to the swing rod. When placing the connecting rod raw material, the connecting rod is guided by the positioning plate, so as to reduce the probability of material deflection when placing the connecting rod raw material.

DETAILED DESCRIPTION

[0041] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0042] The embodiment of the present application discloses a device for machining connecting rods on a flying cutter lathe.

[0043] Example:

[0044] Reference Figure 1 The device for machining connecting rods with a flying cutter lathe comprises a base 1, support seats 3 are arranged at both ends of the base 1 along the length direction, and the base 1 is further provided with an annular cutter disc 2, and the annular cutter disc 2 is located between the two support seats 3. The annular cutter disc 2 comprises an arc seat 21 and a semi-ring frame 22, and the semi-ring frame 22 is located directly above the arc seat 21. The base 1 is provided with a moving component for moving the arc seat 21, and the moving component can select the commonly used technical means in this field, such as a combination of a motor and a lead screw, to drive the arc seat 21 to move longitudinally and transversely. The moving component is a prior art, so it will not be described in detail here.

[0045] Reference Figure 1 and Figure 2, upper connecting blocks 222 are fixed on both sides of the semi-ring frame 22 along the width direction, and the upper connecting blocks 222 are driven to move when the semi-ring frame 22 moves, and lower connecting blocks 212 are fixed on both sides of the arc seat 21, and the upper connecting blocks 222 are located directly above the lower connecting blocks 212, and the lower connecting blocks 212 abut against the upper connecting blocks 222. The upper connecting block 222 is provided with a plurality of locking bolts 223, and all the locking bolts 223 pass through the upper connecting block 222 and are threadedly connected to the lower connecting block 212. Under the action of the locking bolts 223, the arc seat 21 and the semi-ring frame 22 are locked with each other, and the semi-ring frame 22 is driven to move when the arc seat 21 moves. By removing the locking bolts 223, it is convenient to disassemble the semi-ring frame 22 and the arc seat 21.

[0046] Reference Figure 2 A plurality of arc blocks 23 are provided between the semi-ring frame 22 and the arc seat 21. In this embodiment, six arc blocks 23 are provided, and the six arc blocks 23 are connected end to end and abut against each other to form a complete ring. The arc seat 21 is provided with a mounting groove 1 211 along its own arc direction, and the arc seat 21 is provided with a mounting groove 221 corresponding to the mounting groove 1 211. The mounting groove 1 211 and the mounting groove 2 221 are connected to each other, and all the arc blocks 23 are distributed in the mounting groove 1 211 and the mounting groove 2 221.

[0047] Reference Figure 2 , the arc block 23 is fixedly connected with a plurality of evenly distributed tooth blocks along the outer circle, and the arc block 23 is driven to move when the tooth blocks move. The arc seat 21 is equipped with a rotating member 24, and the rotating member 24 is a commonly used technical means in this field. In this embodiment, the rotating member 24 is a motor and a gear, wherein the motor is fixedly connected to the arc seat 21, and the arc seat 21 drives the motor to move when it moves. The arc seat 21 is provided with a cavity connected to the mounting groove 1 211, and the gear is located in the cavity and fixed coaxially with the motor output shaft. When the arc block 23 moves along the mounting groove 1 211, the corresponding tooth blocks mesh with the gears in turn, and when the motor drives the gears to rotate, the gears drive all the arc blocks 23 to move along the mounting groove 1 211 and the mounting groove 2 221 in turn through the tooth blocks.

[0048] Reference Figure 1 and Figure 2 All arc blocks 23 have connecting grooves on one side close to their own axes, and a turning block 25 is also provided between the arc seat 21 and the annular frame, one side of the turning block 25 is inserted into the connecting groove and contacts the arc block 23. The turning block 25 is provided with a mounting bolt, which passes through the turning block 25 and is threadedly connected to the arc block 23. Under the limiting action of the connecting groove and the mounting bolt, the arc block 23 moves and drives the turning block 25 to move.

[0049] Reference Figure 3 and Figure 4A semi-ring block 26 is provided on one side of the arc seat 21, and the semi-ring block 26 is coaxially arranged with the arc seat 21. The arc seat 21 is provided with a guide groove 1 adapted to the semi-ring block 26 along its own arc direction. The semi-ring block 26 is located in the guide groove 1 and is slidably connected with the arc seat 21 along the guide groove 1. The arc seat 21 limits the semi-ring block 26 through the guide groove pair, so that the semi-ring block 26 is driven to move when the arc seat 21 moves. The semi-ring frame 22 is provided with a semi-ring block 27, and the semi-ring block 27 has the same structure as the semi-ring block 26. When the arc seat 21 cooperates with the semi-ring frame 22, the semi-ring block 26 and the semi-ring block 27 are in a coaxial state.

[0050] Reference Figure 3 and Figure 4 , a plurality of evenly arranged driving tooth blocks 261 are fixed on the side of the semi-ring block 1 26 and the semi-ring block 2 27 away from the axis, and a driving motor 28 is installed on the arc seat 21. When the arc seat 21 moves, the driving motor 28 is driven to move. A moving gear 281 is coaxially fixed to the output shaft of the driving motor 28. The operator drives the moving gear 281 to rotate through the driving motor 28. When the semi-ring block 1 26 and the semi-ring block 2 27 are in the working state, the moving gear 281 meshes with the driving tooth block 261. When the moving gear 281 rotates, the semi-ring block 1 26 and the semi-ring block 2 27 are driven to rotate in the circumferential direction through the driving tooth block 261. In the initial state, the semi-ring block 1 26 and the semi-ring block 2 27 are both in a stationary state, and at this time, one side of the semi-ring block 1 26 is in contact with the arc seat 21, and the other side is in contact with the annular frame. The semi-ring block 1 26 and the semi-ring block 27 cooperate to limit the arc seat 21 and the annular frame, which is beneficial to reduce the probability of deflection between the arc seat 21 and the semi-ring frame 22, and at the same time improve the connection stability between the arc seat 21 and the semi-ring frame 22.

[0051] Reference Figure 3 and Figure 4 When the arc seat 21 and the semi-ring frame 22 need to be disassembled, the semi-ring block 1 26 and the semi-ring block 2 27 are driven to rotate by the driving motor 28, so that the connection gap between the semi-ring block 1 26 and the semi-ring block 2 27 is directly opposite to the connection gap between the arc seat 21 and the semi-ring frame 22. When the semi-ring frame 22 is removed, the semi-ring block 2 27 is separated from the semi-ring block 1 26. The upper connecting block 222 is provided with a moving groove 224 in the horizontal direction, and a slot 262 is slidably connected along the length direction of the moving groove 224. The semi-ring block 1 26 and the semi-ring block 2 27 are both provided with a slot 262 adapted to the plug block 225. When the semi-ring block 1 26 and the semi-ring block 2 27 are arranged vertically, any slot 262 is directly opposite to the plug block 225.

[0052] Reference Figure 3 and Figure 4, an elastic member 227 is provided between the plug block 225 and the upper connecting block 222. The elastic member 227 is a spring. One end of the spring is fixedly connected to the plug block 225, and the other end is fixedly connected to the upper connecting block 222. The spring is in a compressed state, exerting a force on the plug block 225 to approach the axis of the semi-ring block 26. A guide block 226 is fixed on one side of the plug block 225. When the guide block 226 moves, it drives the plug block 225 to move. An inclined surface is provided on the end of the guide block 226 close to the semi-ring block 26. The inclined surface is inclined from bottom to top in the direction close to the axis of the semi-ring block 26. A moving block 213 is fixed on the upper end of the lower connecting block 212. An opening connected to the moving groove 224 is provided on the upper connecting block 222. The moving block 213 passes through the opening and abuts against the inclined surface.

[0053] Reference Figure 3 and Figure 4 When the upper connecting block 222 approaches the lower connecting block 212, the moving block 213 pushes the guide block 226 along the inclined surface, so that the guide block 226 drives the plug block 225 away from the semi-ring block 1 26. At this time, the plug block 225 is not easy to interfere with the movement of the semi-ring block 1 26 and the semi-ring block 2 27. When the semi-ring frame 22 needs to be disassembled, the upper connecting block 222 drives the guide block 226 away from the moving block 213 when moving. At this time, the elastic member 227 drives the plug block 225 to approach the corresponding slot 262. When the plug block 225 is inserted into any slot 262, the corresponding semi-ring block 27 or semi-ring block 1 26 is limited, which is conducive to reducing the probability of the semi-ring block 27 or the semi-ring block 1 26 falling off from the semi-ring frame 22.

[0054] Reference Figure 1 and Figure 5 A support platform 31 is provided on one side of the support seat 3 close to the annular cutter disc 2, and the support platform 31 is vertically slidably connected to the support seat 3. A driving member 32 is installed on the support seat 3, and the driving member 32 is a driving device commonly used in the technical field. In this embodiment, the driving member 32 is a jack, and the output end of the jack is fixedly connected to the support platform 31. The operator drives the support platform 31 to move vertically through the jack.

[0055] Reference Figure 1 and Figure 5 When processing the connecting rod, the connecting rod raw material is driven through the annular cutter disc 2 by the lifting equipment, and the two ends of the raw material are respectively in contact with the support platforms 31 of the two support seats 3, and the two support platforms 31 cooperate to support the connecting rod raw material. When the diameter of the end of the connecting rod raw material is too large and it is not easy to pass through the annular cutter disc 2, the annular cutter disc 2 is disassembled by splitting the semi-ring frame 22 and the arc block 23. At this time, the rod body of the connecting rod raw material is directly placed on the axis of the arc seat 21, and the semi-ring frame 22 is installed, so that it is convenient to process the connecting rod raw material with a larger end, which is conducive to expanding the processing range of the annular cutter disc 2.

[0056] Reference Figure 5 and Figure 6 The support seat 3 is provided with a top 33. In the initial state, the top 33 and the annular cutter disc 2 (reference Figure 1 ) are coaxially arranged, the support seat 3 is provided with a fixed cover 34, and the top 33 is located at the fixed cover 34 close to the annular cutter head 2 (reference Figure 1 ) and is slidably connected to the fixing cover 34 along its own axial direction. The fixing cover 34 is provided with a threaded hole 342 coaxial with the top 33, and is threadedly connected with a threaded column 341 adapted to the threaded hole 342. The threaded column 341 is located at the top 33 away from the annular cutter disc 2 (reference Figure 1 The threaded column 341 is rotatably connected to the top 33, and when the threaded column 341 moves along the length direction of the threaded hole 342, it drives the top 33 to move synchronously.

[0057] Reference Figure 6 and Figure 7 The fixed cover 34 is also provided with a positioning rod 37, which passes through the threaded column 341 and the top 33 in sequence and is slidably connected to both. The positioning rod 37 is close to the annular cutter disc 2 (reference Figure 1 ) is provided with a conical portion 371 at one end, the diameter of which is larger than the diameter of the rod body of the positioning rod 37. When the positioning rod 37 moves, the conical portion 371 is driven to move. In the initial state, the conical portion 371 is in conflict with the top 33. Both ends of the connecting rod raw material are provided with a central hole. When placing the raw material, the positioning rod 37 is moved toward the raw material so that the conical portion 371 is close to the raw material.

[0058] Reference Figure 6 and Figure 7 The positioning rod 37 is provided with a slide groove 372 along the length direction, and the positioning rod 37 is slidably connected with a moving rod 373 along the length direction of the slide groove 372. The moving rod 373 is located at the end of the positioning rod 37 away from the tapered portion 371. When the positioning rod 37 moves, the moving rod 373 is driven to move. A push rod 374 is hinged at one end of the moving rod 373 close to the tapered portion 371, and when the moving rod 373 moves, the push rod 374 is driven to move. A swing rod 38 is hinged at the position of the positioning rod 37 close to the tapered portion 371, and one end of the push rod 374 away from the moving rod 373 is hinged to the swing rod 38. When the swing rod 38 moves along the axial direction, the push rod 374 drives the swing rod 38 to swing.

[0059] Reference Figure 6 and Figure 7 The swing rod 38 has a through slot 381 along its length, the through slot 381 is located at one end of the swing rod 38 away from the push rod 374, a plurality of positioning plates 382 are provided along the length direction of the through slot 381, and a plurality of rotating columns 383 corresponding to the positioning plates 382 are vertically fixed to the swing rod 38, the rotating columns 383 pass through the positioning plates 382 and are rotatably connected to the positioning plates 382.

[0060] Reference Figure 7 and Figure 8 A slide bar 384 is also provided in the through slot 381. The slide bar 384 is slidably connected to the swing bar 38 along the length direction of the swing bar 38. The slide bar 384 has a moving opening along the width direction. The positioning plate 382 is fixedly connected to a cylinder. The cylinder is inserted into the moving opening and is slidably connected to the slide bar 384 along the length direction of the moving opening. An elastic member 385 is provided between the moving rod 373 and the positioning rod 37. The elastic member 385 is a spring. One end of the spring is fixedly connected to the moving rod 373, and the other end is fixedly connected to the positioning rod 37.

[0061] Reference Figure 7 and Figure 8 In the initial state, the swing rod 38 is located in the slide groove 372 and is parallel to the positioning rod 37. At this time, the elastic member 385 is in a compressed state, thereby pushing the slide rod 384 away from the tapered portion 371. At this time, all the positioning plates 382 are located in the through groove 381. When the tapered portion 371 approaches the connecting rod material, the moving rod 373 is pushed along the length direction of the positioning rod 37, so that the moving rod 373 drives the swing rod 38 to rotate through the push rod 374. When the swing rod 38 rotates, it drives the elastic member 385 to gradually stretch. When the elastic member 385 stretches, it drives the slide rod 384 to move along the slide groove 372. When the slide rod 384 moves, it drives the positioning plates 382 to flip, so that all the positioning plates 382 are in a state perpendicular to the swing plate. In the process of placing the connecting rod material, the positioning plate 382 is used as a mark so that the center hole is always at the top 33 (reference Figure 5 ) helps reduce the probability of the connecting rod being tilted when placed.

[0062] Reference Figure 1 and Figure 5 Two guide plates 35 are provided at the upper end of the support platform 31. The two guide plates 35 are symmetrically arranged with the support platform 31 as the center. When placing the connecting rod material, the end of the material is passed through the gap between the two guide plates 35 and approaches the support platform 31. The two guide plates 35 cooperate to limit the connecting rod material and reduce the probability of shaking of the connecting rod material. The support seat 3 is provided with a transverse groove along the width direction, and a bidirectional lead screw is rotatably connected along the transverse groove. Both ends of the bidirectional lead screw are threadedly connected with sliders. The slider is located in the transverse groove and fits with the inner wall of the transverse groove. Under the limiting effect of the transverse groove, the two sliders are driven to move synchronously when the bidirectional lead screw rotates.

[0063] Reference Figure 1 and Figure 5The slider corresponds to the guide block 226 one by one and is fixedly connected. When the slider moves, it drives the guide block 226 to move, so as to facilitate the adjustment of the distance between the two guide blocks 226. The support seat 3 is provided with a mobile motor 36. The output end of the mobile motor 36 is coaxially fixed with the bidirectional lead screw. It is convenient to drive the bidirectional lead screw to rotate by the mobile motor 36. Two support plates 311 are hinged at the upper end of the support platform 31. When the connecting rod material contacts the upper end of the support platform 31, it is located between the two support plates 311. The support platform 31 is installed with a hydraulic cylinder 312. The hydraulic cylinder 312 is used to drive the support plate 311 to rotate. In the initial state, the support plate 311 is in a horizontal state. When the connecting rod is placed, the support plate 311 is mobilized to rotate by the hydraulic cylinder 312, so that the two support plates 311 cooperate to limit the connecting rod material.

[0064] Reference Figure 5 and Figure 7 After the connecting rod material contacts the support platform 31, the moving rod 373 is reset, and the swing rod 38 drives the positioning plate 382 to be stored in the slide groove 372. The positioning rod 37 is moved so that the positioning rod 37 drives the tapered portion 371 to approach the connecting rod material. At this time, if the tapered portion 371 is facing the center hole, the threaded column 341 is rotated so that the threaded column 341 drives the top 33 to move toward the center hole. If the tapered portion 371 is not facing the center hole, the position of the connecting rod material is adjusted. It is more convenient to move the positioning rod 37, thereby reducing the time spent on the position of the connecting rod material.

[0065] Reference Figure 1 and Figure 5 The support platform 31 cooperates with the top 33 to position the two ends of the connecting rod. When the arc block 23 drives the turning block 25 to move, the rod body of the connecting rod raw material is turned. The shape requirements for the connecting rod end are relatively low, which is conducive to improving the convenience of processing the connecting rod.

[0066] The present application also discloses a method for using a device for machining a connecting rod on a flying cutter lathe, comprising the following steps:

[0067] Process both ends of the connecting rod raw material to make the end surface of the raw material flat, measure the center line of the connecting rod blank, and drill a center hole on the end surface;

[0068] The raw material is moved by the lifting equipment so that one end of the raw material passes through the annular cutter disc 2, and the two ends of the raw material are placed on the corresponding support platforms 31 respectively. At this time, the two hydraulic cylinders 312 drive the support plates 311 to approach each other, so that the two support plates 311 cooperate to limit the raw material;

[0069] The support platform 31 is driven by the driving member 32 to move vertically so that the center hole is directly opposite to the top 33;

[0070] The top point 33 is moved so that it is inserted into the center hole. At this time, the support seat 3 limits the top point 33 through the fixing rod, so that the two groups of top points 33 cooperate to limit the raw material.

[0071] The implementation principle of the device for processing connecting rods on a flying cutter lathe of the embodiment of the present application is as follows: marking and drilling a center hole at both ends of the connecting rod raw material, moving the connecting rod raw material through a hoisting device, so that the connecting rod raw material passes through the annular cutter disc 2, and the two ends of the connecting rod raw material are in contact with the support platform 31, and the two hydraulic cylinders 312 drive the corresponding support plates 311 to rotate, so that the support plates 311 cooperate to limit the displacement of the connecting rod raw material in the lateral direction. The support platform 31 is adjusted by a jack so that the center hole is aligned with the top 33, and the positioning rod 37 is moved. When it is determined that the conical portion 371 is aligned with the center hole, the threaded column 341 is rotated so that the threaded column 341 pushes the top 33 to be inserted into the center hole. At this time, two groups of tops 33 and two groups of support platforms 31 cooperate to support and position the connecting rod raw material, and the requirements for the end structure of the connecting rod raw material are relatively low, thereby facilitating the fixed processing of the connecting rod raw material, which is conducive to improving the convenience of processing the connecting rod.

[0072] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
