However, since the gear is round, the gear may rotate during the clamping process, causing the gear to slip during the cutting process, thereby causing gear damage and greatly reducing the gear qualification rate. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5 , a cutting device for gearbox gear production, comprising a base 1, a cutting mechanism 2 is fixedly mounted on the base 1, a placing plate 3 is fixedly mounted on the base 1, and a gear is placed on the placing plate 3;

[0023] A mounting column 4 is fixedly mounted on the placement plate 3, a T-shaped hole is opened on the mounting column 4, a moving block 5 is symmetrically and horizontally slidably mounted in the T-shaped hole, a first spring rod 6 is horizontally fixedly mounted on the side of the two moving blocks 5 away from each other, a positioning block 7 is fixedly mounted on one end of the two first spring rods 6, and the positioning block 7 is inserted in the keyway of the gear, and a transmission component for driving the two moving blocks 5 to move away from each other is provided on the mounting column 4;

[0024] A mounting hole is provided in the middle part of the gear, and key slots are symmetrically provided on the inner wall of the mounting hole. When the gear is placed on the placement disk 3, the gear is sleeved on the mounting column 4, and then the gear is rotated to align the two key slots on the gear with the two positioning blocks 7, and then the two moving blocks 5 in the T-shaped hole are driven away from each other through the transmission assembly. The moving block 5 drives the positioning block 7 to move into the gear key slot through the first spring rod 6 until the two positioning blocks 7 are respectively inserted into the two key slots and contact the inner walls of the key slots, and two forces in different directions are applied to the gear through the two positioning blocks 7, so that the gear is clamped and fixed on the placement disk 3. At the same time, the key slot is restricted by the positioning block 7, which can prevent the gear from rotating during the processing, making it more stably clamped, avoiding damage to the gear during processing, and effectively improving the qualified rate of the gear.

[0025] The transmission assembly includes a U-shaped frame 10 fixedly mounted on the mounting column 4, a threaded rod 11, a lifting block 12 threadedly sleeved on the threaded rod 11, and two support rods 13 symmetrically rotatably mounted on the lifting block 12. A rotating hole is provided on the U-shaped frame 10, and the threaded rod 11 is rotatably inserted in the rotating hole, and the lower end is rotatably connected to the bottom wall of the T-shaped hole. One end of the two support rods 13 away from the lifting block 12 is rotatably connected to the two moving blocks 5 respectively. An adjusting block 14 is fixedly mounted on the upper end of the threaded rod 11, and an anti-slip pattern is provided on the adjusting block 14.

[0026] When it is necessary to drive the two moving blocks 5 away from each other, the adjusting block 14 can be rotated to drive the threaded rod 11 to rotate. Since the lifting block 12 is threadedly sleeved on the threaded rod 11, the lifting block 12 will be driven to move vertically downward, and then the two moving blocks 5 will be driven away from each other through the two support rods 13.

[0027] First struts 8 are rotatably mounted on both sides of the positioning block 7, and the ends of the two first struts 8 away from the positioning block 7 are hinged with second struts 9, and the ends of the two second struts 9 away from the first struts 8 are rotatably connected to the moving block 5, and the hinges of the first struts 8 and the second struts 9 are in contact with the inner wall of the keyway of the gear;

[0028] When the positioning block 7 contacts the inner wall of the keyway, the moving block 5 continues to move, and the first spring rod 6 is compressed. At this time, the first support rod 8 and the second support rod 9 rotate, and the hinge between the first support rod 8 and the second support rod 9 moves away from the first spring rod 6 and moves toward the side wall of the keyway until it contacts the side wall of the keyway, applying two opposite forces to the two side walls of the keyway, thereby preventing relative sliding between the positioning block 7 and the inner wall of the keyway.

[0029] The second spring rods 15 are symmetrically fixedly mounted on the mounting column 4, and an L-shaped rod 16 is rotatably mounted on the upper ends of the two second spring rods 15. A spherical groove is opened at one end of the two upper L-shaped rods 16, and a ball 17 is rotatably embedded in the two spherical grooves. The two balls 17 are in rolling contact with the upper surface of the gear.

[0030] After the gear is placed on the placement plate 3, the second spring rod 15 can be stretched first, and then the L-shaped rod 16 can be rotated to drive the ball 17 to move above the gear, and then the second spring rod 15 is released. Under the action of elastic force, the ball 17 contacts the upper surface of the gear, thereby limiting the gear from moving upward.

[0031] The surfaces of the two positioning blocks 7 are fixedly mounted with protective pads made of rubber. When the positioning blocks 7 are in contact with the inner wall of the keyway, the protective pads can protect the inner wall of the keyway.

[0032] In the utility model, the two moving blocks 5 in the T-shaped hole are driven away from each other by the transmission component, so that the positioning block 7 is driven to move into the gear keyway through the first spring rod 6 until it contacts the inner wall of the keyway, and two forces in two different directions are applied to the gear by the two positioning blocks 7, so that the gear is clamped and fixed on the placement plate 3. At the same time, the positioning block 7 is restricted by the keyway to prevent the gear from rotating during the processing, so that the clamping is more stable, the gear is prevented from being damaged during processing, and the qualified rate of the gear is effectively improved.

[0033] In general, in view of the technical problem that during the clamping process, the gear may rotate, causing the gear to slide during the cutting process, thereby causing gear damage, greatly reducing the qualified rate of the gear; adopting a technical solution: through the mutual cooperation of the positioning column 4, the transmission assembly, the moving block 5, the first spring rod 6 and the positioning block 7, the gear can be clamped and positioned while preventing the gear from rotating during the processing; because the implementation process of the technical solution is: the two moving blocks 5 in the T-shaped hole are driven away from each other by the transmission assembly, so that the positioning block 7 is driven by the first spring rod 6 to move into the gear keyway until it contacts the inner wall of the keyway, and two positioning blocks 7 apply forces in two different directions to the gear, so that the gear is clamped and fixed on the placement plate 3, and at the same time, the positioning block 7 can prevent the gear from rotating during the processing under the restriction of the keyway, so that the clamping is more stable; so the technical problem can be solved inevitably, and the technical effect achieved is: avoiding damage to the gear during processing and effectively improving the qualified rate of the gear.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
