Description

Technical Field

[0001] This utility model relates to the field of wheel rim cutting technology, specifically a wheel rim cutting machine. Background Technology

[0002] Generally, tires must be installed on a vehicle with rims. In addition to securing the tires, rims also allow the wheels to make smooth contact with the ground to generate forward motion. The production of rims mainly involves casting a rough rim blank, and then precision machining and hole repair on the end face and surface of the cast rim blank to form the finished rim.

[0003] Currently, wheel rims are typically cut using a lathe. First, the lathe fixture fixes the wheel rim, then the motor drives the fixture to rotate the wheel rim, which is then cut using a cutting tool. After cutting, the motor needs to be stopped before the fixture can be released from its grip on the wheel rim. However, since the fixture is directly connected to the motor, when controlling the fixture to release or fix the wheel rim, the operator needs to hold the fixture body to prevent it from rotating, which is inconvenient and inefficient. Therefore, we propose a wheel rim cutting machine. Utility Model Content

[0004] The purpose of this invention is to provide a wheel rim cutting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wheel rim cutting machine, including a cutting lathe, a cutting tool mounted on the cutting lathe, and a drive clamping assembly mounted on the cutting lathe, the drive clamping assembly comprising:

[0006] The drive unit controls the clamping unit to perform clamping operations and can drive the clamping unit to rotate the wheel rim for cutting.

[0007] The clamping part is used to fix the wheel rim;

[0008] The limiting part is used to limit the clamping part.

[0009] Preferably, the drive unit includes a motor, which is fixed inside the cutting lathe. The output shaft of the motor is connected to a screw via a pulley and a belt. The screw is rotatably mounted on the inner wall of the cutting lathe and is threadedly connected to a threaded block. A support rod is hinged to the right side of the threaded block. When the clamping part is restricted from rotating by the limiting part, the clamping part can restrict the threaded block via the support rod. When the motor drives the screw to rotate via the pulley and belt, the screw can control the movement of the threaded block, thereby controlling the clamping part to fix or release the wheel rim.

[0010] Preferably, the clamping part includes a disc, which is rotatably mounted on the inner side of the cutting lathe. The left side of the disc is rotatably connected to the right side of the screw. A sliding groove is provided on the disc, and a moving rod is slidably mounted on the inner side of the sliding groove. A support rod is provided on the side of the moving rod near the center of the disc. The left side of the moving rod is hinged to the end of the support rod away from the threaded block. When the threaded block moves to the left or right, the moving rod can be controlled by the support rod to move the support rod, thereby fixing or contacting the wheel rim, without the need for manual operation of the clamping fixture by the operator.

[0011] Preferably, the limiting part includes a fixed gear ring fixed to the inner side of the cutting lathe; a connecting rod is fixed to the side of the support rod near the moving rod, the connecting rod passing through the moving rod and slidably connected to the moving rod; a connecting spring is fixed to the side of the support rod near the moving rod, the end of the connecting spring away from the support rod is fixed to the moving rod; a movable rod is hinged to the end of the connecting rod away from the support rod, the end of the movable rod away from the connecting rod is hinged to one end of the vertical rod; the vertical rod passes through the moving rod and is slidably connected to the moving rod; a hinged rod is hinged to the other end of the vertical rod, the end of the hinged rod away from the vertical rod is hinged to... A push rod passes through and is slidably connected to a movable rod. A horizontal plate is slidably mounted on the inner wall of the disc. A second movable rod is hinged to the top of the horizontal plate. The end of the second movable rod away from the horizontal plate is hinged to the bottom of an L-shaped plate. A third movable rod is hinged to the side of the L-shaped plate. A movable locking tooth is hinged to the end of the third movable rod away from the L-shaped plate. The movable locking tooth passes through and is slidably connected to the disc. A support spring is fixed to the end of the movable locking tooth away from the fixed tooth ring. The end of the support spring away from the movable locking tooth is fixed to a fixed plate. The fixed plate is fixed to the inner wall of the disc, preventing the support rod from being compressed. At this time, the push rod is in contact with the horizontal plate, preventing the horizontal plate from moving closer to the push rod. Consequently, the movable retaining tooth cannot move into the disc, and the movable retaining tooth is fully engaged with the fixed toothed ring, thus restricting the disc. Therefore, when the screw rotates, the threaded block can move closer to the disc. The threaded block can be controlled by the support rod to open the moving rod, fixing the wheel rim. When the support rod is against the inside of the wheel rim and in contact with the moving rod, the wheel rim is fixed. At this point, the support rod and connecting rod retract into the moving rod. The connecting rod, through the movable rod, pushes the vertical rod closer to the push rod. The vertical rod, through the hinge rod, pushes the push rod... The rod retracts into the moving rod, so that the push rod no longer abuts against the cross plate. At this time, the restriction on the movable locking tooth is released. When the screw continues to rotate, the screw applies a rotational force to the threaded block. The threaded block applies a rotational force to the moving rod and the disk through the support rod. At this time, the inclined surface of the movable locking tooth abuts against the inclined surface of the fixed tooth ring tooth, causing the movable locking tooth to move into the disk. This does not affect the normal rotation of the disk, so that the fixed wheel rim can rotate together. The cutting tool can then perform the cutting operation on the wheel rim. There is no need for the operator to manually control the clamping operation of the wheel rim. The drive rotation and clamping are integrated into one operation, which effectively improves the overall efficiency.

[0012] Preferably, a through hole is provided on the inner side of the groove on the disc, through which the push rod can pass and move together with the moving rod.

[0013] Compared with the prior art, the present invention provides a wheel rim cutting machine, which has the following advantages:

[0014] 1. This wheel rim cutting machine, through its drive unit, clamping unit, and limiting unit, secures the wheel rim by having the support rod abut against the inside of the wheel rim and engage with the moving rod. At this point, the restriction on the movable locking teeth can be released, and the inclined surface of the movable locking teeth abuts against the inclined surface of the fixed locking ring teeth, causing the movable locking teeth to move inward into the disc without affecting the normal rotation of the disc. This allows the fixed wheel rim to rotate together, enabling the cutting tool to perform the cutting operation on the wheel rim. This eliminates the need for manual control of the wheel rim clamping operation, integrating the drive rotation and clamping operations into one, effectively improving overall efficiency.

[0015] 2. When the wheel rim cutting machine needs to disassemble the cut wheel rim, it is only necessary to control the motor to drive the screw to rotate in the opposite direction. The screw applies a force to the disc in the opposite direction through the threaded block and the support rod. At this time, the vertical surface of the movable tooth tooth abuts against the vertical surface of the fixed tooth ring tooth tooth, so that the disc cannot rotate in the opposite direction. Thus, the threaded block can only reset along the screw. By controlling the moving rod and the support rod to reset through the support rod, the fixing of the wheel rim is released, and the wheel rim can be removed. Attached Figure Description

[0023] like Figures 1-6 As shown, this utility model provides a technical solution: a wheel rim cutting machine, including a cutting lathe 1, a cutting tool 5 on the cutting lathe 1, and a drive clamping assembly on the cutting lathe 1, the drive clamping assembly including: a drive part 2, a clamping part 3, and a limiting part 4.

[0024] The drive unit 2 includes a motor 21, which is fixed inside the cutting lathe 1. The output shaft of the motor 21 is connected to the screw 24 via a pulley 22 and a belt 23. The screw 24 is rotatably mounted on the inner wall of the cutting lathe 1 and is threadedly connected to a threaded block 25. A support rod 26 is hinged to the right side of the threaded block 25. When the clamping unit 3 is restricted from rotating by the limiting unit 4, the clamping unit 3 can restrict the threaded block 25 via the support rod 26. When the motor 21 drives the screw 24 to rotate via the pulley 22 and the belt 23, the screw 24 can control the movement of the threaded block 25, thereby controlling the clamping unit 3 to fix or release the wheel rim.

[0025] The fixture part 3 includes a disc 31, which is rotatably mounted on the inside of the cutting lathe 1. The left side of the disc 31 is rotatably connected to the right side of the screw 24. A sliding groove is provided on the disc 31, and a moving rod 32 is slidably mounted on the inside of the sliding groove. A support rod 33 is provided on the side of the moving rod 32 near the center of the disc 31. The left side of the moving rod 32 is hinged to the end of the support rod 26 away from the threaded block 25. When the threaded block 25 moves to the left or right, the moving rod 32 can be controlled by the support rod 26 to move the support rod 33, thereby fixing or contacting the wheel rim. No manual operation of the fixture is required for clamping. A through hole is provided on the inside of the sliding groove on the disc 31, through which a push rod 47 can pass and move together with the moving rod 32.

[0026] The limiting part 4 includes a fixed gear ring 41, which is fixed to the inner side of the cutting lathe 1. A connecting rod 42 is fixed to the side of the support rod 33 near the moving rod 32. The connecting rod 42 passes through the moving rod 32 and is slidably connected to it. A connecting spring 43 is fixed to the side of the support rod 33 near the moving rod 32. The end of the connecting spring 43 away from the support rod 33 is fixed to the moving rod 32. A movable rod 45 is hinged to the end of the connecting rod 42 away from the support rod 33. The end of the movable rod 45 away from the connecting rod 42 is hinged to one end of a vertical rod 44. The vertical rod 44 passes through the moving rod 32 and is slidably connected to it. A hinge rod 46 is hinged to the other end of the vertical rod 44. A push rod 47 is hinged to the end of the hinge rod 46 away from the vertical rod 44. The push rod 47 passes through the moving rod 32 and... A horizontal plate 48 is slidably mounted on the inner wall of the disc 31, connected to the movable rod 32. A movable rod 49 is hinged to the top of the horizontal plate 48. The end of the movable rod 49 away from the horizontal plate 48 is hinged to the bottom of the L-shaped plate 410. A movable rod 411 is hinged to the side of the L-shaped plate 410. A movable tooth 412 is hinged to the end of the movable rod 411 away from the L-shaped plate 410. The movable tooth 412 passes through the disc 31 and is slidably connected to the disc 31. A support spring 413 is fixed to the end of the movable tooth 412 away from the fixed tooth ring 41. The end of the support spring 413 away from the movable tooth 412 is fixed to the fixed plate 414. The fixed plate 414 is fixed to the inner wall of the disc 31. When the support rod 33 is not compressed, the push rod 47 is in contact with the horizontal plate 48. The horizontal plate 48 cannot move towards the side closer to the push rod 47, thus preventing the movable locking tooth 412 from moving into the disc 31. The movable locking tooth 412 is fully engaged with the fixed toothed ring 41, restricting the disc 31. Therefore, when the screw 24 rotates, the threaded block 25 can move towards the side closer to the disc 31. The threaded block 25 can control the moving rod 32 to open the support rod 33 via the support rod 26, thus fixing the wheel rim. When the support rod 33 abuts against the inside of the wheel rim and is in contact with the moving rod 32, the wheel rim is fixed. At this time, the support rod 33 and the connecting rod 42 retract into the moving rod 32. The connecting rod 42 pushes the vertical rod 44 towards the side closer to the push rod 47 via the movable rod 45. The vertical rod 44 pushes the push rod 47 into the moving rod via the hinge rod 46. Within 32, the push rod 47 no longer contacts the cross plate 48, thus releasing the restriction on the movable retaining tooth 412. As the screw 24 continues to rotate, it applies a rotational force to the threaded block 25. The threaded block 25, through the support rod 26, applies a rotational force to the moving rod 32 and the disc 31. At this time, the inclined surface of the teeth of the movable retaining tooth 412 contacts the inclined surface of the teeth of the fixed toothed ring 41, causing the movable retaining tooth 412 to move into the disc 31. This does not affect the normal rotation of the disc 31, allowing it to rotate along with the fixed wheel rim. The cutting tool 5 can then perform the cutting operation on the wheel rim without requiring manual control of the wheel rim clamping operation. This integrated operation of drive rotation and clamping effectively improves overall efficiency. When the wheel rim needs to be disassembled after cutting, this further enhances efficiency.Simply control motor 21 to drive screw 24 to rotate in the opposite direction. Screw 24 applies a force to disk 31 in the opposite direction through threaded block 25 and support rod 26. At this time, the vertical surface of the teeth of movable retaining tooth 412 abuts against the vertical surface of the teeth of fixed toothed ring 41, preventing disk 31 from rotating in the opposite direction. Thus, threaded block 25 can only reset along screw 24. The support rod 26 controls the resetting of moving rod 32 and support rod 33, thereby releasing the wheel rim from fixation. At this point, the wheel rim can be removed.

[0027] In this invention, during use, the wheel rim to be cut is first fitted onto the moving rod 32 and the support rod 33. The motor 21 is then started, and the motor 21 drives the screw 24 to rotate via the pulley 22 and the belt 23. At this time, the push rod 47 is in contact with the horizontal plate 48, and the horizontal plate 48 cannot move towards the side closer to the push rod 47. Consequently, the movable locking tooth 412 cannot move into the disc 31. The movable locking tooth 412 is fully engaged with the fixed toothed ring 41, thus restricting the disc 31. Therefore, when the screw 24 rotates, the threaded block 25 can move towards the side closer to the disc 31. The threaded block 25 can be moved by the support rod 26, which controls the moving rod 32 to open the support rod 33, thus fixing the wheel rim. When the support rod 33 abuts against the inside of the wheel rim and fits against the moving rod 32, the wheel rim is fixed. At this time, the support rod 33 and the connecting rod 42 retract into the moving rod 32. The connecting rod 42 pushes the vertical rod 44 to move closer to the push rod 47 via the movable rod 45. The vertical rod 44 pushes the push rod 47 into the moving rod 32 via the hinge rod 46, so that the push rod 47 no longer abuts against the horizontal plate 48. At this time, the restriction on the movable locking tooth 412 is released. As the screw 24 continues to rotate, it applies a rotational force to the threaded block 25. The threaded block 25, through the support rod 26, applies a rotational force to the moving rod 32 and the disk 31. At this time, the inclined surface of the teeth of the movable retaining tooth 412 abuts against the inclined surface of the teeth of the fixed toothed ring 41, causing the movable retaining tooth 412 to move inward into the disk 31. This does not affect the normal rotation of the disk 31, allowing it to rotate along with the fixed wheel rim. The cutting tool 5 can then perform the cutting operation on the wheel rim. This eliminates the need for manual control of the wheel rim clamping operation, integrating the drive rotation and clamping operations into one, effectively... This improves overall efficiency. When the wheel rim needs to be disassembled after cutting, simply control the motor 21 to drive the screw 24 to rotate in the opposite direction. The screw 24 applies a force to the disc 31 in the opposite direction through the threaded block 25 and the support rod 26. At this time, the vertical surface of the teeth of the movable retaining tooth 412 abuts against the vertical surface of the teeth of the fixed tooth ring 41, so that the disc 31 cannot rotate in the opposite direction. Thus, the threaded block 25 can only be reset along the screw 24. The moving rod 32 and the support rod 33 are reset through the support rod 26, thereby releasing the fixation of the wheel rim. At this time, the wheel rim can be removed.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
