Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, and specifically relates to a turning device for hollow long shaft parts. Background Technology

[0002] Hollow long-shaft automotive parts are important components in automobile manufacturing, typically used in transmission systems, steering systems, or other areas requiring high strength and lightweight design. These parts are characterized by their long length and hollow internal structure, which helps reduce weight while maintaining sufficient strength and rigidity. The production of hollow long-shaft parts requires the use of turning equipment.

[0003] Existing turning equipment for hollow long shaft parts places the part to be turned on a specialized fixture or chuck. The fixture or chuck clamps and secures the part, ensuring a stable hold and preventing displacement or bending during machining. The chuck then rotates the part, controlling the cutting tool's movement speed and position along the workpiece's length to smoothly cut the inner wall. However, in practice, the cutting tool's position is usually fixed during this process. Since different models and specifications of hollow long shaft parts require different cutting methods, operators must stop the machine and adjust the settings to ensure the cutting tool is in the correct position. This adjustment requires time and effort, significantly increasing the workload and impacting processing efficiency. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a turning device for hollow long shaft parts. It can quickly and stably adjust the position of the cutting tool according to the model, specifications and processing needs of the hollow long shaft parts, saving the time required for debugging and effectively improving processing efficiency.

[0006] As a further improvement of this utility model, the adjustment module includes a bidirectional lead screw 1 rotatably disposed inside the turning cylinder. Symmetrically distributed adjustment blocks are threaded to the outer side of the bidirectional lead screw 1. Multiple connecting rods are rotatably disposed on the outer side of each adjustment block. The ends of the connecting rods furthest from the adjustment blocks are rotatably connected to adjacent adjustment frames. A motor 5 is disposed in the center of the rotating cylinder. The output shaft of motor 5 is fixed to the bidirectional lead screw 1 via a coupling. An external gear ring 2 is fixedly sleeved on the outer arc surface of the rotating cylinder. A U-shaped seat 2 is disposed at the bottom of the turning box. A gear 2 is rotatably disposed between the U-shaped seat 2 and the turning box via a rotating rod. The gear 2 meshes with the external gear ring 2. A worm gear is fixedly sleeved on the outer arc surface of the rotating rod. Symmetrically distributed support plates are disposed at the bottom of the turning box. A worm is rotatably disposed between the support plates. The worm meshes with the worm gear. A motor 3 is disposed inside the turning box. The output shaft of motor 3 is fixed to the worm via a coupling.

[0007] As a further improvement of this utility model, a slide table is slidably arranged between the guide rails. A sliding seat is provided on the upper surface of the slide table, and a sliding frame is slidably arranged on the upper side of the sliding seat. Adjusting seats are symmetrically distributed in the sliding groove at the upper end of the sliding frame. A support wheel is rotatably arranged in the middle of each adjusting seat. A double-acting screw is rotatably arranged inside the sliding groove. A motor is arranged on the outer side of the sliding frame. The output shaft of the motor is fixed to the double-acting screw through a coupling. A hydraulic push rod is symmetrically distributed on the upper surface of the slide table, and the telescopic ends of the hydraulic push rods are all connected and fixed to the sliding frame. A buffer rubber ring is glued and fixed to the outer arc surface of each support wheel.

[0008] As a further improvement of this utility model, an external gear ring is fixedly sleeved on the outer side of the four-jaw chuck, a U-shaped seat is provided at the bottom of the control box, a gear is rotatably arranged inside the U-shaped seat via a rotating shaft, the gear meshes with the external gear ring, a motor is provided at the bottom of the control box, and the output shaft of the motor is fixed to the rotating shaft via a coupling; an integrated controller is provided on the front side of the control box, and the hydraulic push rod, motor one, motor two, motor three, motor four, and motor five are all electrically connected to the integrated controller.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, when the sliding table reaches a suitable position, the integrated controller controls the operation of motor 2 and the hydraulic push rod. Through the cooperation of motor 2 and hydraulic push rod, the horizontal and vertical positions of the support wheel can be adjusted so that the support wheel is in the optimal position to support the hollow long shaft part.

[0011] Secondly, the hollow long shaft part to be turned is placed on the four-jaw chuck for positioning. The hollow long shaft part is supported by the support wheels on both sides. The integrated controller controls the operation of the motor, which in turn drives the turning box to approach the hollow long shaft part to be turned, so that the turning cylinder is inserted into the interior of the hollow long shaft part.

[0012] Third, the integrated controller controls the operation of motor five, causing the output shaft of motor five to drive the bidirectional lead screw one connected to it to rotate. Through the threaded relationship between the bidirectional lead screw one and the adjusting block, the adjusting blocks on both sides are driven to move in opposite directions, thereby adjusting the extension length of the adjusting frame. The adjusting frame drives the turning tool away from the turning cylinder, thereby adjusting the distance between the turning tool and the turning cylinder.

[0013] Fourth, the integrated controller regulates the operation of the three motors, and through the meshing relationship between the worm and the worm wheel, the worm wheel is driven to rotate back and forth, which causes the turning cylinder to drive the turning tool set on the outside of the turning cylinder to rotate back and forth around the transverse center of the turning cylinder. This allows the turning tool to rotate back and forth around the transverse center of the turning cylinder, and to perform fast and stable turning on the inner wall of the hollow long shaft part during the rotation process.

[0014] Fifth, during the reciprocating rotation of the turning tool around the transverse center of the rotating cylinder, the integrated controller controls the motor to continue running, so that the turning tool steadily and gradually moves away from the turning cylinder during the reciprocating rotation of the turning tool around the transverse center of the rotating cylinder, and can quickly and stably turn the inner wall of hollow long shaft parts of different models and specifications during the rotation.

[0025] like Figure 4 , 5 As shown, the adjustment module includes a bidirectional lead screw 206 rotatably mounted inside the turning cylinder 203. Symmetrically distributed adjustment blocks 207 are threaded to the outer side of the bidirectional lead screw 206. Multiple connecting rods 208 are rotatably mounted on the outer side of each adjustment block 207. The ends of the connecting rods 208 furthest from the adjustment blocks 207 are rotatably connected to adjacent adjustment frames 204. A motor 5 is located in the center of the rotating cylinder 202. The output shaft of the motor 5 is fixed to the bidirectional lead screw 206 via a coupling. An external gear ring 209 is fixedly fitted onto the outer arc surface of the rotating cylinder 202. A U-shaped seat 210 is located at the bottom of the turning box 201. A gear 211 is rotatably mounted between the U-shaped seat 210 and the turning box 201 via a rotating rod. Gear 211 meshes with external gear ring 209. A worm gear is fixedly sleeved on the outer arc surface of the rotating rod.

[0026] like Figure 2 , 3 As shown, a slide table 110 is slidably arranged between guide rails 109. A sliding seat 111 is provided on the upper surface of the slide table 110. A sliding frame 112 is slidably arranged on the upper side of the sliding seat 111. A symmetrically distributed adjusting seat 113 is slidably arranged in the sliding groove opened at the upper end of the sliding frame 112. A support wheel 114 is rotatably arranged in the middle of each adjusting seat 113. A two-way lead screw is rotatably arranged inside the sliding groove. A motor 115 is arranged on the outer side of the sliding frame 112. The output shaft of the motor 115 is fixed to the two-way lead screw through a coupling. A symmetrically distributed hydraulic push rod is provided on the upper surface of the slide table 110. The telescopic ends of the hydraulic push rods are all connected and fixed to the sliding frame 112.

[0027] like Figure 1 As shown, an integrated controller 301 is installed on the front side of the control box 103. The hydraulic push rod, motor 108, motor 215, motor 3214, motor 4217, and motor 5 are all electrically connected to the integrated controller 301.

[0028] In use, slide the slide table 110 to a suitable position so that the support wheel 114 is in the optimal position to support the hollow long shaft part. Then, the integrated controller 301 controls the operation of the motor 115, so that the output shaft of the motor 115 drives the double-acting screw 2 to rotate. Through the threaded relationship between the double-acting screw 2 and the adjusting seat 113, the adjusting seat 113 is moved towards or away from each other, thus adjusting the horizontal position of the support wheel 114. The integrated controller 301 controls the operation of the hydraulic push rod, so that the extension end of the hydraulic push rod drives the sliding frame 112 to slide between the sliding seat 111, thus adjusting the vertical position of the support wheel 114. Through the cooperation of the motor 115 and the hydraulic push rod, the horizontal and vertical positions of the support wheel 114 can be adjusted so that the support wheel 114 is in the optimal position to support the hollow long shaft part.

[0029] The hollow long shaft part to be turned is placed on the four-jaw chuck 104, and then the four-jaw chuck 104 clamps and fixes the hollow long shaft part and positions it. At this time, the hollow long shaft part is in contact with the support wheels 114 on both sides, and the support wheels 114 on both sides provide auxiliary support for the hollow long shaft part.

[0030] The integrated controller 301 controls the operation of motor 217, causing the output shaft of motor 217 to drive the adjusting screw 216 connected to it to rotate. By adjusting the thread relationship between the adjusting screw 216 and the turning box 201, the turning box 201 is driven to slide between the guide rails 109, thereby driving the turning box 201 to approach the hollow long shaft part to be turned, so that the turning cylinder 203 is inserted into the interior of the hollow long shaft part.

[0031] Then, the integrated controller 301 controls the operation of motor five, causing the output shaft of motor five to drive the bidirectional lead screw 206 connected to it to rotate. Through the threaded relationship between the bidirectional lead screw 206 and the adjusting block 207, the adjusting blocks 207 on both sides move in opposite directions. During the movement of the adjusting block 207: the adjusting block 207 rotates with the connecting rod 208, and the connecting rod 208 rotates with the adjusting frame 204. This causes the adjusting block 207 to slide between the adjusting frame 204 and the turning cylinder 203 through the connecting rod 208, thereby adjusting the extension length of the adjusting frame 204. The adjusting frame 204 drives the turning tool 205 away from the turning cylinder 203, thereby adjusting the distance between the turning tool 205 and the turning cylinder 203.

[0032] Then, the integrated controller 301 controls the operation of the motor 214, so that the output shaft of the motor 214 drives the worm 213 connected to it to rotate in both directions. Through the meshing relationship between the worm 213 and the worm wheel, the worm wheel is driven to rotate in both directions. Through the meshing relationship between the gear 211 and the external gear ring 209, the rotating cylinder 202 where the external gear ring 209 is located is driven to rotate in both directions. This causes the rotating cylinder 202 to drive the turning tool 205 set on the outside of the turning cylinder 203 to rotate in both directions around the transverse center of the rotating cylinder 202.

[0033] The integrated controller 301 controls the operation of motor 108, which drives gear 107 to rotate. Through the meshing relationship between gear 107 and external gear ring 105, the four-jaw chuck 104 containing external gear ring 105 rotates. Through the cooperation between four-jaw chuck 104 and support wheel 114, the hollow long shaft part rotates. By coordinating the rotation of the hollow long shaft part with the rotation of the turning tool 205 around its axis, the centrifugal force can be effectively counteracted, thereby reducing the risk of workpiece deformation.

[0034] During the reciprocating rotation of the turning tool 205 around the transverse center of the rotating cylinder 202, the integrated controller 301 controls the motor 5 to continue running, so that the turning tool 205 steadily and gradually moves away from the turning cylinder 203 during the reciprocating rotation of the turning tool 205 around the transverse center of the rotating cylinder 202, and performs rapid and stable turning on the inner wall of the hollow long shaft part during the rotation process.

[0035] According to another embodiment of the present invention, such as Figure 3 As shown, buffer rubber rings are bonded and fixed to the outer arc surface of the support wheel 114. When turning the inner wall of the hollow long shaft part, the buffer rubber rings on the outside of the support wheel 114 allow the inner wall of the hollow long shaft part to make flexible contact with the support wheel 114, which can effectively prevent wear on the outer wall of the hollow long shaft part during the turning process.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
