Description

Technical Field

[0001] This invention relates to the field of automotive repair machinery, specifically a coaxial and rail-mounted rotating tool bar hub machine. Background Technology

[0002] Currently, the optical disc repair machine and the wheel hub repair machine on the market are different machines for repairing and processing brake discs and wheel hubs. This results in disadvantages such as large space occupation, high cost and low processing efficiency.

[0003] Currently, there are also solutions that integrate cutting and grinding into one machine. One solution is to drive the spindle that mounts the brake disc and wheel hub to move axially to achieve feed. This method requires a long spindle, which leads to a decrease in strength, large vibration, and consequently a decrease in machining accuracy. Another solution is to use a vertical drive shaft to drive the spindle that mounts the brake disc and wheel hub perpendicularly to each other through a transmission mechanism for machining. The disadvantage of this structure is that the transmission is complex. Summary of the Invention

[0004] This invention provides a coaxial and rail-mounted rolling cutter bar hub machine, the purpose of which is to overcome the shortcomings of the prior art, realize the machining of brake discs and wheel hubs on a single machine tool, reduce costs, improve production efficiency, reduce space occupation, strengthen the mechanism, and improve machining accuracy.

[0005] The technical solution adopted by this invention to solve its technical problem is: The coaxial and rail-guided turning cutter bar hub machine is characterized by: The motor inside the spindle box on the machine tool drives the longitudinal spindle, and the front end of the spindle is equipped with a clamp; The machine is equipped with a transverse feed system that connects to and drives the main tool post. The main tool post is equipped with a longitudinal feed system, which connects to and drives the front optical disc tool post, the rear optical disc tool post, and the optical hub tool post, which are installed on the main tool post from front to back. A front optical disc cutter bar is mounted on the front optical disc cutter holder, and a front optical disc cutter is mounted at the end of the front optical disc cutter bar; A rear disc cutter bar is mounted on the rear disc cutter holder, and a rear disc cutter is mounted on the end of the rear disc cutter bar; The optical hub tool holder is equipped with an optical hub tool shank, and the end of the optical hub tool shank is equipped with an optical hub tool.

[0006] The front optical disc cutter bar and the front optical disc cutter holder are connected by a hinge point, and the rear optical disc cutter bar and the rear optical disc cutter holder are connected by a hinge point.

[0007] The transverse feed system consists of a main tool post nut mounted on the main tool post that engages with a transverse lead screw pivotally mounted on the machine base. The transverse lead screw is driven by a handwheel or a motor.

[0008] A handwheel is installed at the end of the transverse lead screw, and a clutch is provided between the motor output shaft and the transverse lead screw.

[0009] The longitudinal feed is as follows: a longitudinal lead screw is pivotally mounted at the front of the main tool holder, a handwheel is installed at the front end of the lead screw, and the nut of the front disc tool holder is engaged with the lead screw; The rear of the main tool post is pivotally equipped with a longitudinal rear lead screw, and the nut of the rear optical disc tool post is engaged with the rear lead screw; the nut of the optical hub tool post is engaged with the rear lead screw; the rear lead screw is driven by a handwheel or a motor.

[0010] A handwheel is installed at the rear end of the lead screw, and a clutch is provided between the motor output shaft and the lead screw.

[0011] The front lead screw and the rear lead screw are separate.

[0012] The front optical disc tool holder, rear optical disc tool holder, and optical hub tool holder are respectively matched with the guide rails provided on the main tool holder.

[0013] The advantages of this invention are: The present invention uses the same spindle for machining the brake disc and wheel hub, and the spindle only rotates without axial feed. This eliminates the need for a very long spindle, improves structural strength, avoids the disadvantages of reduced strength and vibration caused by a long spindle, and improves machining accuracy.

[0014] In this invention, the optical disc cutter holder and the optical hub cutter holder are located on the same main cutter holder and on the same longitudinal track. By moving the optical disc cutter holder (selectively flipping up and down, rotating in and out, or pulling laterally), the optical disc cutter moves aside, thereby avoiding interference between the optical disc cutter and the optical hub cutter. This shortens the length of the optical disc cutter holder and the optical hub cutter holder, improves structural strength, avoids the disadvantages of reduced strength and vibration caused by long cutter holders, and improves machining accuracy.

[0015] This invention is easy to use; switching between optical disc processing and optical hub processing only requires moving the optical disc tool holder to avoid interference. Attached Figure Description

For those skilled in the art, other embodiments can be obtained based on these drawings without creative effort. To facilitate understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figure 1 As shown: The motor inside the spindle box 1 on the machine tool drives the longitudinal spindle 2. The front end of the spindle 2 is equipped with a clamp, and a brake disc 31 is installed on the clamp.

[0022] The main tool post nut 41 installed on the main tool post 4 cooperates with the transverse lead screw 8 pivotally mounted on the machine base. A handwheel 81 is installed at the end of the transverse lead screw 8. A clutch 84 is provided between the output shaft 83 of the motor 82 and the transverse lead screw 8.

[0023] In this way, turning the handwheel 81 can drive the transverse lead screw 8 to rotate, thereby causing the main tool holder nut 41 to drive the main tool holder 4 to move laterally in the direction of the transverse lead screw 8.

[0024] When the clutch 84 is disengaged, the output shaft 83 of the motor 82 can be disconnected from the transverse lead screw 8, so that the transverse lead screw 8 can only be driven to rotate by the handwheel 81. When the clutch 84 is engaged, the output shaft 83 of the motor 82 can also drive the transverse lead screw 8.

[0025] The front of the main tool holder 4 is pivotally equipped with a longitudinal lead screw 71. A handwheel 72 is installed at the front end of the lead screw 71. The nut of the front optical disc tool holder 51 is engaged with the lead screw 71. The front optical disc tool holder 51 is engaged with the guide rail provided on the main tool holder 4.

[0026] A front optical disc cutter bar 52 is mounted on the front optical disc cutter holder 51, and a front optical disc cutter 53 is mounted on the end of the front optical disc cutter bar 52. The front optical disc cutter bar 52 can swing up and down or horizontally around its hinge point with the front optical disc cutter holder 51 and then be fixed. The front optical disc cutter bar 52 can also be moved laterally and then fixed. In this way, the front optical disc cutter 53 can make way to avoid interference during optical disc hub processing.

[0027] In this way, turning the handwheel 72 can drive the front lead screw 71 to rotate, and the front lead screw 71 drives the front optical disc cutter holder 51, the front optical disc guide rod 52, and the front optical disc cutter 53 to move longitudinally.

[0028] The rear of the main tool holder 4 is pivotally equipped with a longitudinal rear lead screw 73. The nut of the rear optical disc cutter holder 54 is engaged with the rear lead screw 73, and the rear optical disc cutter holder 54 is engaged with the guide rail provided on the main tool holder 4.

[0029] A rear optical disc cutter bar 55 is mounted on the rear optical disc cutter holder 54, and a rear optical disc cutter 56 is mounted on the end of the rear optical disc cutter bar 55. The rear optical disc cutter bar 55 can swing up and down or horizontally around its hinge point with the rear optical disc cutter holder 54 and then be fixed. The rear optical disc cutter bar 55 can also be moved laterally and then fixed. In this way, the rear optical disc cutter 56 can make way to avoid interference during optical disc machining.

[0030] The nut of the optical hub tool holder 6 is engaged with the rear lead screw 73, and the optical hub tool holder 6 is engaged with the guide rail provided on the main tool holder 4.

[0031] A hub tool holder 6 is mounted on a hub tool holder 6, and a hub tool 62 is mounted on the end of the hub tool holder 61.

[0032] The optical hub tool holder 6 is located behind the rear optical disc tool holder 54.

[0033] A handwheel 74 is installed at the rear end of the lead screw 73, and a clutch 77 is provided between the output shaft 76 of the motor 75 and the lead screw 73.

[0034] In this way, turning the handwheel 74 can drive the rear lead screw 73 to rotate, thereby causing the nut of the rear optical disc cutter holder 54 to drive the rear optical disc cutter holder 54, the rear optical disc cutter bar 55, and the rear optical disc cutter 56 to move longitudinally in the direction of the rear lead screw 73, and the nut of the optical hub cutter holder 6 to drive the optical hub cutter holder 6, the optical hub cutter bar 61, and the optical hub cutter 62 to move longitudinally in the direction of the rear lead screw 73.

[0035] When the clutch 77 is disengaged, the output shaft 76 of the motor 75 can be disconnected from the rear lead screw 73, so the rear lead screw 73 can only be driven to rotate by the handwheel 74. When the clutch 77 is engaged, the output shaft 76 of the motor 75 can also drive the rear lead screw 73.

[0036] The front lead screw 71 and the rear lead screw 73 are separate.

[0037] The front optical disc cutter 53, the rear optical disc cutter 56, and the optical hub cutter 62 are located on the same side of the main tool holder 4.

[0038] When machining brake disc 31, i.e., during optical disc machining: Rotate handwheel 72 to adjust the position of the front optical disc cutter 53, and rotate handwheel 74 to adjust the position of the rear optical disc cutter 56. After the adjustment is in place, use motor 82 to drive the transverse lead screw 8, which in turn drives the main tool holder 4 to move laterally. The front optical disc cutter 53 and the rear optical disc cutter 56 move laterally to cut the brake disc 31.

[0039] like Figure 2 As shown: A hub 32 is mounted on the clamp at the front end of the spindle 2.

[0040] The front optical disc cutter bar 52 swings up and down around its hinge point with the front optical disc cutter holder 51 and then is fixed. The rear optical disc cutter bar 55 swings up and down around its hinge point with the rear optical disc cutter holder 54 and then is fixed. In this way, the front optical disc cutter 53 and the rear optical disc cutter 56 are moved away from their original positions and avoid the longitudinal front position of the optical hub cutter 62, thus avoiding interference.

[0041] Rotate handwheel 81 to move main tool holder 4. This adjusts the position of hub cutter 62. After hub cutter 62 is in place, motor 75 drives rear lead screw 73, and hub cutter 62 moves longitudinally in the direction of rear lead screw 73 to cut hub 32.

[0042] like Figure 3 As shown: A hub 32 is mounted on the clamp at the front end of the spindle 2.

[0043] The front optical disc cutter bar 52 swings horizontally around its hinge point with the front optical disc cutter holder 51 and then is fixed. The rear optical disc cutter bar 55 swings horizontally around its hinge point with the rear optical disc cutter holder 54 and then is fixed. In this way, the front optical disc cutter 53 and the rear optical disc cutter 56 are moved away from their original positions, avoiding the longitudinal front position of the optical hub cutter 62 and avoiding interference.

[0044] Rotate handwheel 81 to move main tool holder 4. This adjusts the position of hub cutter 62. After hub cutter 62 is in place, motor 75 drives rear lead screw 73, and hub cutter 62 moves longitudinally in the direction of rear lead screw 73 to cut hub 32.

[0045] like Figure 3 As shown: A hub 32 is mounted on the clamp at the front end of the spindle 2.

[0046] After the front optical disc cutter bar 52 is moved laterally and then fixed, and the rear optical disc cutter bar 55 is moved laterally and then fixed, the front optical disc cutter 53 and the rear optical disc cutter 56 are moved away from their original positions, avoiding the longitudinal front position of the optical hub cutter 62 and preventing interference.

[0047] Rotate handwheel 81 to move main tool holder 4. This adjusts the position of hub cutter 62. After hub cutter 62 is in place, motor 75 drives rear lead screw 73, and hub cutter 62 moves longitudinally in the direction of rear lead screw 73 to cut hub 32.
