Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to an angle adjustment mechanism for a CNC rotary gear chamfering machine. Background Technology

[0002] With the development of the automotive industry, the requirements for gear processing quality are becoming increasingly stringent. Gear cutting processes, such as gear hobbing, gear shaping, and spline cutting, will produce a large number of flanged burrs on the end face of the gear after processing. These burrs have high hardness. If these burrs are not removed or are not removed cleanly, they will seriously affect the function and life of related devices, and may even cause serious damage and paralyze the entire set of equipment. Therefore, chamfering the gears is an indispensable process in gear processing, and this process is generally completed using a gear chamfering machine.

[0003] When processing gears of different specifications or with different chamfering requirements, the angle needs to be adjusted. The existing adjustment method is to rotate the gear to drive the gear plate to adjust the angle of the material to be processed. Since the meshing between the gears is completed instantaneously, certain impacts and vibrations may occur when operating at high speed or with large load changes, thus affecting the accuracy of the angle adjustment. Therefore, an angle adjustment mechanism for a CNC rotary gear chamfering machine is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an angle adjustment mechanism for a CNC rotary gear chamfering machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an angle adjustment mechanism for a CNC rotary gear chamfering machine, comprising a base, two sliding grooves on the top of the base, a fixed plate movably disposed within the two sliding grooves, a column movably disposed on the top of the fixed plate, a sliding plate fixedly disposed on the front of the column, two machining tools movably disposed on the front of the sliding plate, an adjustment structure within the base, a spindle box on the adjustment structure, a torque motor and a clamp respectively disposed on both sides of the spindle box, a locking structure on the front of the base, and a scale plate fixedly disposed on the front of the base.

[0006] As a further description of the above technical solution:

[0007] The adjustment structure includes a rotating shaft movably connected to the inner wall of the top of the base and a rotating rod movably connected to the inner wall of the front of the base. One end of the rotating rod is fixedly provided with a worm gear. The top and bottom ends of the rotating shaft are respectively fixedly provided with a mounting plate and a worm wheel. The worm wheel and the worm gear are adapted to each other. The end of the rotating rod away from the worm gear is fixedly provided with a rotating disk.

[0008] As a further description of the above technical solution:

[0009] The top of the base is provided with a limiting groove, the bottom of the mounting plate is fixedly provided with a connecting rod, the bottom of the connecting rod is fixedly provided with a sliding block, and the sliding block and the limiting groove are movably connected.

[0010] As a further description of the above technical solution:

[0011] The rotating disk has multiple rectangular plates fixed to its exterior, and a triangular indicator is provided on the front of the rotating disk.

[0012] As a further description of the above technical solution:

[0013] The base has round holes on its top inner wall and front inner wall. Bearings are fixedly installed in both round holes, and the inner rings of the two bearings are respectively fixedly sleeved on the rotating shaft and the rotating rod.

[0014] As a further description of the above technical solution:

[0015] The locking structure includes a mounting plate fixedly connected to the base, a pull rod movably mounted on the mounting plate, and insert plates and pull handles fixedly mounted at both ends of the pull rod.

[0016] As a further description of the above technical solution:

[0017] A spring is fitted onto the pull rod, with one end of the spring fitting against the mounting plate and the other end fitting against one side of the insert plate.

[0018] As a further description of the above technical solution:

[0019] The base has four rectangular support blocks fixedly installed at its bottom, and each of the four support blocks has an anti-slip pad fixedly installed at its bottom.

[0020] This utility model has the following beneficial effects:

[0021] 1. Compared with existing technologies, the angle adjustment mechanism of this CNC rotary gear chamfering machine, through the setting of a rotating shaft, rotating rod, worm gear, mounting plate, worm wheel, connecting rod, support block, rotating disk and rectangular plate, allows for angle adjustment by pulling the handle to one side, causing the insert plate to disengage from two adjacent rectangular plates. Then, the rotating disk is rotated, which drives the rotating rod, which in turn drives the worm gear, causing the mounting plate to rotate. This achieves the adjustment of the angle of the material to be processed. The meshing clearance between the worm gear and worm can be controlled to be very small, and due to the continuity and gradualness of its transmission process, the accuracy of angle adjustment can be ensured.

[0022] 2. Compared with the existing technology, the angle adjustment mechanism of this CNC rotary gear chamfering machine is equipped with a mounting plate, a pull rod, a insert plate, a pull handle, and a spring. After the adjustment is completed, the pull handle is released, and the insert plate returns to its original position and is inserted between the two rectangular plates due to the pushing force of the spring, thereby achieving the positioning of the rotating disk. This can effectively prevent the rotating rod from rotating due to the vibration of the equipment during operation, which would cause the angle of the material to change. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 4The present invention provides an angle adjustment mechanism for a CNC rotary gear chamfering machine: including a base 1, four rectangular support blocks fixedly arranged at the bottom of the base 1, and anti-slip measures fixedly provided at the bottom of each of the four support blocks; two sliding grooves 2 on the top of the base 1, a fixed plate 3 movably arranged in the two sliding grooves 2, a column 4 movably arranged on the top of the fixed plate 3, a sliding plate 5 fixedly arranged on the front of the column 4, two processing tools 6 movably arranged on the front of the sliding plate 5; a spindle box 8 on the adjustment structure 7, a torque motor 9 and a clamp 10 respectively arranged on both sides of the spindle box 8; and a scale 12 fixedly arranged on the front of the base 1.

[0031] To improve adjustment accuracy, the machine base 1 is equipped with an adjustment structure 7. The adjustment structure 7 includes a rotating shaft 701 movably connected to the inner wall of the top of the machine base 1 and a rotating rod 702 movably connected to the inner wall of the front of the machine base 1. Both the inner wall of the top and the inner wall of the front of the machine base 1 have circular holes, and bearings are fixedly installed in both holes. The inner rings of the two bearings are respectively fixedly fitted onto the rotating shaft 701 and the rotating rod 702. A worm gear 703 is fixedly installed at one end of the rotating rod 702. A mounting plate 704 and a worm wheel 705 are fixedly installed at the top and bottom of the rotating shaft 701, respectively. A limiting groove is provided at the top of the machine base 1, and a limiting groove is fixedly installed at the bottom of the mounting plate 704. A connecting rod 706 is provided, and a sliding block 707 is fixedly provided at the bottom of the connecting rod 706. The sliding block 707 is movably connected to the limiting groove. The worm wheel 705 and the worm 703 are adapted to each other. A rotating disk 708 is fixedly provided at the end of the rotating rod 702 away from the worm 703. Multiple rectangular plates 709 are fixedly provided on the outside of the rotating disk 708. A triangular indicator is provided on the front of the rotating disk 708. The angle is adjusted by the cooperation of the worm 703 and the worm wheel 705. The meshing clearance between the worm wheel 705 and the worm 703 can be controlled to be very small. And due to the continuity and gradualness of its transmission process, the accuracy of angle adjustment can be ensured.

[0032] To achieve the positioning purpose, a locking structure 11 is provided on the front of the base 1. The locking structure 11 includes a mounting plate 111 fixedly connected to the base 1. A pull rod 112 is movably mounted on the mounting plate 111. Insert plates 113 and pull handles 114 are fixedly mounted on both ends of the pull rod 112, respectively. A spring 115 is sleeved on the pull rod 112. One end of the spring 115 is in contact with the mounting plate 111, and the other end of the spring 115 is in contact with one side of the insert plate 113. After adjustment, the pull handle 114 is released. Due to the pushing force of the spring 115, the insert plate 113 returns to its original position and is inserted between the two rectangular plates 709, thereby achieving the positioning of the rotating disk 708 and preventing the rotating rod 702 from rotating due to vibration during equipment operation, which would cause the angle of the material to change.

[0033] Working principle: When adjusting the angle of the gear to be processed, first pull the handle 114 to one side. The handle 114 drives the pull rod 112, which in turn drives the insert plate 113. When the insert plate 113 disengages from between two adjacent rectangular plates 709, the rotating disk 708 is rotated. The rotating disk 708 drives the rotating rod 702 and the triangular indicator. The use of the triangular indicator and the scale 12 allows relevant personnel to more intuitively determine the rotation angle. The operation is simple. The rotating rod 702 drives the worm gear 703, which in turn drives the worm wheel 705 to rotate the mounting plate 704, thereby realizing the adjustment of the angle of the material to be processed. The worm gear 703 drive is a type of interleaved shaft drive with a large transmission ratio. During power transmission, the helical teeth of the worm gear 703 gradually mesh with the teeth of the worm wheel 705 to achieve angle adjustment. The meshing gap between the worm wheel 705 and the worm gear 703 can be controlled to be very small. Furthermore, due to the continuity and gradualness of its transmission process, the accuracy of angle adjustment can be ensured. After adjustment, the pull handle 114 is released, and the insert plate 113 returns to its original position and is inserted between the two rectangular plates 709 under the thrust of the spring 115, thereby positioning the rotating disk 708 and preventing the rotating rod 702 from rotating due to equipment vibration, which would cause the angle of the material to change.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
