Abstract
Description
Technical Field
[0001] This utility model relates to the field of gear processing, specifically a cutting device for gear processing. Background Technology
[0002] A gear is a mechanical component with continuously meshing gears on its rim to transmit motion and power. During the gear manufacturing process, the teeth need to be cut, which is the most important step in gear processing. The teeth are cut into the same size and spacing to ensure that the gear is qualified and can then mesh to transmit motion and power when used.
[0003] Current mobile rock breaking devices for tunnel construction, as described in patent CN216607509U, include a worktable and a support plate. The support plate is fixedly installed on one side of the worktable, and a fixing mechanism, a cutting mechanism, and a clamping mechanism are respectively arranged on top of the worktable. The fixing mechanism includes a servo motor, a turntable, a support column, a placement plate, a groove, a trapezoidal locking block, and gears. The servo motor is fixedly installed inside one side of the worktable, and the turntable is connected to the servo motor via an output shaft. The support column is fixedly installed above the turntable.
[0004] Regarding the aforementioned technologies, the inventors believe the working principle of this fixing device is as follows: When the gear is placed on the placement plate from above the support column, the downward-moving gear pushes the trapezoidal locking block into the groove, causing the spring to contract. When the gear has completely passed through the trapezoidal locking block and is in contact with the placement plate, the trapezoidal locking block automatically pops out under the action of the spring force, thereby fixing the gear. However, since the distance between the placement plate and the trapezoidal locking block is fixed, this device can only fix gears of a specific height, which severely limits the applicability of the cutting device. Utility Model Content
[0005] The purpose of this invention is to provide a cutting device for gear processing to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

The adjusting screw is rotatably connected to two sets of the movable seats. A cutting seat is threadedly connected to the outer side of the adjusting screw. A cutting tool is rotatably connected inside the cutting seat. A drive motor is fixedly connected to one side of the cutting seat.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] With the above-described structure, this invention utilizes the cooperation of the lower support column, pressure column, first hydraulic rod, and sliding seat. The top of the lower support column is designed as a tapered structure, allowing the gear to be cut to be placed on top of the lower support column. Simultaneously, the tapered structure at the top of the lower support column can be inserted into the shaft hole inside the gear. When the first hydraulic rod is activated, it drives the sliding seat and pressure column downwards. During this process, the pressure column pushes the gear, adjusting it to a horizontal position. Because the top of the lower support column is tapered, after the gear is pressed horizontally, it can maintain a coaxial alignment with the pressure column and lower support column, ultimately clamping and fixing the gear. This allows for fixed cutting of gears of different heights, thereby improving the applicability of the entire cutting device. Attached Figure Description

A lower support column 103 is rotatably connected inside the support plate 101 to support the gear. The top of the lower support column 103 is tapered, which facilitates insertion into the shaft hole inside the gear. When the gear is adjusted to a horizontal position, it remains coaxial with the lower support column 103. A vertical plate 102 is fixedly connected to one side of the support plate 101.

The end of the diagonal brace 114 away from the top plate 115 is fixedly connected to the vertical plate 102. The diagonal brace 114 is used to further connect and fix the top plate 115 and the vertical plate 102, thereby improving the connection stability between the top plate 115 and the vertical plate 102. A pressure column 105 corresponding to the lower support column 103 is rotatably connected inside the sliding seat 104. The pressure column 105 is used to press and fix the gear at the top of the lower support column 103 when moving downward.
[0026] The bottom of the pressure column 105 is provided with a groove 116, which is adapted to the lower support column 103. The groove 116 is provided to avoid the top of the lower support column 103. The top of the upright plate 102 is fixedly connected to a top plate 115. A first hydraulic rod 106 is fixedly installed through the interior of the top plate 115. The output ends of both sets of first hydraulic rods 106 are fixedly connected to the sliding seat 104. The first hydraulic rods 106 are provided to drive the sliding seat 104 and the pressure column 105 to move up and down when the operation is started.
[0027] First bevel gears 107 are fixedly connected to the opposite sides of the pressure column 105 and the lower support column 103. Rotary shafts 109 are rotatably connected to the opposite sides of the sliding seat 104 and the support plate 101. Second bevel gears 108 are fixedly connected to one side of each of the two sets of rotating shafts 109, and the two sets of second bevel gears 108 mesh with the two sets of first bevel gears 107 respectively. The rotating shafts 109 are configured to drive the first bevel gears 107 to rotate when rotated. Third bevel gears 110 are fixedly connected to the other end of each of the two sets of rotating shafts 109. Fourth bevel gears 111 are meshed with the outer sides of each of the two sets of third bevel gears 110. The two sets of fourth bevel gears 111 are rotatably connected to the upright plate 102 and the sliding seat 104 respectively. The fourth bevel gears 111 are configured to drive the third bevel gears 110 to rotate when rotated.
[0028] A first stepper motor 113 is fixedly connected to the top of the top plate 115. A hexagonal shaft 112 is fixedly connected to the output end of the first stepper motor 113. The hexagonal shaft 112 slides through the upper fourth bevel gear 111. The first stepper motor 113 is configured to drive the hexagonal shaft 112 to rotate when the machine starts working. When the hexagonal shaft 112 rotates, it can drive the two sets of fourth bevel gears 111 to rotate synchronously. The cutting mechanism 2 includes a movable seat 202 that is slidably connected to the support plate 101 and the inside of the top plate 115. A second stepper motor 203 is fixedly connected to the top of the upper movable seat 202. An adjusting screw 204 is fixedly connected to the output end of the second stepper motor 203.

A second hydraulic rod 209 is fixedly installed through one side of the top plate 115 and the support plate 101. The output ends of the two sets of second hydraulic rods 209 are fixedly connected to the two sets of movable seats 202 respectively. The second hydraulic rods 209 are used to pull the movable seats 202 to slide when the work is started.
[0029] An adjusting screw 204 is rotatably connected to two sets of movable seats 202. A cutting seat 206 is threaded onto the outer side of the adjusting screw 204. The adjusting screw 204 is configured to drive the cutting seat 206 up and down during rotation. Guide rods 205 slide symmetrically through the interior of the cutting seat 206.

[0030] In use, the gear to be cut is placed on top of the lower support column 103, so that the top of the tapered lower support column 103 can be inserted into the shaft hole inside the gear. Then, the first hydraulic rod 106 is activated, which drives the sliding seat 104 and the pressure column 105 downwards until the pressure column 105 can press and fix the gear on top of the lower support column 103. Next, the drive motor 208 is activated, which drives the cutter 207 to rotate. Then, according to the required cutting depth of the gear edge, two sets of second hydraulic rods 209 are activated, which drive two sets of moving seats 202 to slide, thereby driving the adjusting screw 204, the cutting seat 206 and the cutter 207 to move until the cutter 207 is adjusted to the required position. Then, the second stepper motor 203 is activated, which drives the first stepper motor 207 to rotate downwards. The second stepper motor 203 drives the adjusting screw 204 to rotate. When the adjusting screw 204 rotates, it can drive the cutting seat 206 and the cutter 207 to move up and down, so that the cutter 207 can cut the edge of the gear when it contacts the edge of the gear. At the same time, it can start the first stepper motor 113, so that when the first stepper motor 113 starts working, it can drive the hexagonal shaft 112 to rotate. When the hexagonal shaft 112 rotates, it can drive the two sets of fourth bevel gears 111 to rotate. When the two sets of fourth bevel gears 111 rotate, they can drive the two sets of third bevel gears 110, the rotating shaft 109 and the second bevel gear 108 to rotate synchronously. When the two sets of second bevel gears 108 rotate synchronously, they can drive the two sets of first bevel gears 107 to rotate synchronously. In turn, they drive the pressure column 105, the lower support column 103 and the gear that is pressed and fixed to rotate, so as to cut different positions on the edge of the gear.
