Description

Technical Field

[0001] This invention belongs to the field of gear positioning technology, specifically a gear processing positioning device. Background Technology

[0002] Gears are mechanical parts with toothed structures that transmit power and motion through meshing, enabling changes in speed, torque, or direction. Based on their axial position and tooth profile, gears can be classified into parallel shaft gears, intersecting shaft gears, and staggered shaft gears. They have advantages such as high transmission accuracy, wide applicable power range, and long service life, and are widely used in the automotive industry, aerospace, engineering machinery, and other fields.

[0003] A patent with publication number CN120155614 discloses a gear processing positioning device, belonging to the field of gear processing technology. This gear processing positioning device includes a base, on which a placement platform is fixedly mounted. Both the base and the placement platform have through grooves inside, and a spreading mechanism is slidably connected inside the through grooves. A driving mechanism for driving the spreading mechanism downwards is fixedly mounted inside the base. Three sets of linkage mechanisms are provided on the surface of the placement platform, and three sets of locking mechanisms are slidably connected inside the placement platform. The spreading mechanism is placed in the middle of the gear. The hinge joint of the first and second brackets fits against the inner wall of the gear for initial fixing. The ends of the first and second brackets are provided with protrusions to increase friction with the inner wall of the gear. Then, the driving mechanism is activated, causing the spreading mechanism to move downwards, simultaneously driving the gear to contact the surface of the placement platform and applying a downward force to the gear surface, further improving the gear fixing effect A.

[0004] In current technologies, gear machining requires positional constraints. Due to the numerous teeth on the gear surface, multi-directional positioning is necessary to maintain gear surface stability. This makes it difficult to change angles after the gear is engaged and positioned, requiring disassembly, reorientation, and further machining. This process is overly cumbersome, and the secondary positioning necessitates repositioning the gear. Because of the numerous teeth on the gear surface, small angle changes and machining are impossible due to the obstruction of the teeth, and the gear cannot always remain centered during machining.

[0005] Therefore, the present invention provides a gear machining positioning device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0008] Preferably, a rotating disk is movably sleeved on the top surface of the positioning disk, a hydraulic pump is fixedly installed on the top surface of the rotating disk, and a pusher is fixedly connected to the output end of the hydraulic pump.

[0009] Preferably, a swing plate is oscillatingly connected to the top surface of the rotating disk and located at the periphery of the hydraulic pump, and the outer surface of the swing plate is movably overlapped with the inner wall of the gear disk.

[0010] Preferably, a recessed groove is formed on the top surface of the metal forming table, and limit strips are fixedly connected to the inner walls on both sides of the recessed groove.

[0011] Preferably, a slot is formed on the bottom inner wall of the recessed groove, and an interlaced limiting cylinder is fixedly connected to the bottom surface of the metal forming table at the middle position.

[0012] Preferably, two bidirectional threaded rods are movably sleeved on the inner wall of the staggered limiting cylinder, a limiting plate is provided on the bottom surface of the metal forming table and at the four edges, the two ends of the bidirectional threaded rods extend to the outer surface of the limiting plate, and a support base is fixedly connected to the bottom surface of the metal forming table and at the four edges of the staggered limiting cylinder.

[0013] Preferably, four sets of hydraulic rods are fixedly installed on the top surface of the support base, and the output ends of the hydraulic rods extend through the metal forming table to the top surface, and the output ends of the hydraulic rods are movably connected to the bottom surface of the gear disk.

[0014] Preferably, a threaded slider is fixedly connected to the bottom surface of the gear positioning frame, and the inner wall of the threaded slider is threadedly and movably sleeved on the outer surface of the bidirectional threaded rod.

[0015] Preferably, a limiting support frame is fixedly connected to the inner wall of the gear positioning frame, one end of the limiting support frame is movably sleeved on the outer surface of the transmission rod, and an arc-shaped fitting plate is provided on one side surface of the gear positioning frame, the outer surface of the arc-shaped fitting plate is movably overlapped on the outer surface of the gear disk.

[0016] Preferably, a positioning box is fixedly installed on the top surface of the metal forming table and at one edge position. The positioning box is equipped with a hydraulic lifting rod, and a transverse moving arm is fixedly connected to the output end of the hydraulic lifting rod. A processor is provided on the output end of the transverse moving arm.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The gear processing positioning device of the present invention comprises a gear disk overlapping the outer surface of a swing plate, and the bottom surface of the gear disk overlapping by a rotating disk. At this time, a hydraulic pump is used to lift the pushing disk. As the pushing disk rises, it will squeeze and adhere to the inner wall of the swing plate, and cause the swing plate to expand outward, so that the outer surface of the swing plate adheres to the inner wall of the gear disk, and the position of the gear disk is defined, so that the gear disk can be in the center position of the positioning disk.

[0019] 2. The gear processing positioning device of the present invention, when the gear disk is processed in the later stage, when the gear disk is rotated in conjunction with the positioning chuck, the rotating disk on the bottom surface of the hydraulic pump rotates on the top surface of the positioning disk. When the rotating disk rotates, it can only rotate on the top surface of the positioning disk. At the same time, under the limitation of the swing plate, the gear disk can be positioned in the original position.

[0020] 3. The gear processing positioning device of the present invention, when the gear disk is positioned on the outer surface of the swing plate, the double-threaded rod rotates on the outer surface of the limiting plate, so that the threaded slider slides in the same direction on the surface of the double-threaded rod, and drives the push positioning toothed discs on the outer surface of the two sets of gear positioning frames to engage with the outer surface of the gear disk. The two sets of push positioning toothed discs limit the position of the two sides of the gear disk. At the same time, the push positioning toothed discs can be rotated so that the toothed discs on the outer surface of the push positioning toothed discs can be firmly engaged with the toothed discs on the surface of the gear disk, thereby limiting the two sides of the gear disk.

[0021] 4. The gear processing positioning device of the present invention places the gear disk on the top outer surface of the metal forming table, and positions the gear disk at the center position of the top of the metal forming table by the positioning disk. At this time, the push positioning tooth plate on the inner wall of the gear positioning frame is engaged with the tooth on the outer surface of the gear disk, and the tooth of the push positioning tooth plate is used to position the gear disk. Moreover, the staggered engagement between the tooth can prevent the gear disk from shaking and shifting position.

[0022] 5. The gear processing positioning device of the present invention, after the independent positions on the surface of the gear disk are processed, rotates the transmission rod with the help of the handle, thereby driving the push positioning toothed disc on the outer surface of the transmission rod to rotate. When the push positioning toothed disc rotates, the teeth on the outer surface of the push positioning toothed disc rotate together with the teeth on the outer surface of the gear disk. During the rotation, the gear disk rotates at the center position on the top of the metal forming table. At the same time, the push positioning toothed discs at the other four positions on the outer surface of the gear disk also rotate together with the rotation of the gear disk. At this time, the four push positioning toothed discs on the surface of the gear disk remain in the same position, so that the gear disk will not shift in position. Thus, the gear disk can be rotated to change the processing position without changing the original position of the gear disk or disassembling the fixing device on the surface of the gear disk.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figures 1 to 10 As shown, a gear processing positioning device according to an embodiment of the present invention includes a metal forming table 11 and four sets of gear positioning frames 12 movably sleeved on the outer surface of the top of the metal forming table 11, a positioning disk 13 fixedly installed on the outer surface of the top of the metal forming table 11 and located in the middle position, a gear disk 14 movably sleeved on the top of the metal forming table 11 and the outer surface of the positioning disk 13, a transmission rod 123 movably sleeved on the outer surface of the gear positioning frame 12, a push positioning toothed disc 124 fixedly connected to the outer surfaces of the upper and lower ends of the transmission rod 123, and the outer surface of the push positioning toothed disc 124 movably sleeved on the outer surface of the gear disk 14.

[0037] The gear disk 14 is placed on the top outer surface of the metal forming table 11, and the gear disk 14 is positioned at the center of the top of the metal forming table 11 by the positioning disk 13. At this time, the push positioning toothed disk 124 on the inner wall of the gear positioning frame 12 is engaged with the toothed disk on the outer surface of the gear disk 14, and the toothed disk 14 is positioned by the toothed disk 124. Moreover, the staggered engagement between the toothed disks prevents the gear disk 14 from shaking or shifting in position.

[0038] At this time, after the independent positions on the surface of the gear disk 14 are machined, the transmission rod 123 is rotated with the grip, which in turn drives the push positioning toothed disc 124 on the outer surface of the transmission rod 123 to rotate. When the push positioning toothed disc 124 rotates, the teeth on the outer surface of the push positioning toothed disc 124 will drive the teeth on the outer surface of the gear disk 14 to rotate together. During the rotation, the gear disk 14 rotates at the center position on the top of the metal forming table 11. At the same time, the push positioning toothed discs 124 at the other four positions on the outer surface of the gear disk 14 will also rotate together with the rotation of the gear disk 14. At this time, the four push positioning toothed discs 124 on the surface of the gear disk 14 will not cause the gear disk 14 to shift in position without changing the original position of the gear disk 14 or disassembling the surface fixing device of the gear disk 14. This achieves the effect of changing the machining position of the gear disk 14 by rotation without changing the original position of the gear disk 14 or disassembling the surface fixing device of the gear disk 14.

[0039] like Figures 1-3 , Figure 5 , Figures 7 to 8 and Figure 10 As shown, a rotating disk 131 is movably sleeved on the top surface of the positioning disk 13. A hydraulic pump 132 is fixedly installed on the top surface of the rotating disk 131. A push disk 133 is fixedly connected to the output end of the hydraulic pump 132. A swinging flexible plate 134 is swayingly connected to the top surface of the rotating disk 131 and located at the periphery of the hydraulic pump 132. The outer surface of the swinging flexible plate 134 is movably overlapped with the inner wall of the gear disk 14.

[0040] The gear disk 14 is overlapped on the outer surface of the swing plate 134, and the bottom surface of the gear disk 14 is overlapped by the rotating disk 131. At this time, the hydraulic pump 132 is used to lift the push disk 133. As the push disk 133 rises, it will squeeze and adhere to the inner wall of the swing plate 134, and cause the swing plate 134 to expand outward. The outer surface of the swing plate 134 is attached to the inner wall of the gear disk 14, and the position of the gear disk 14 is defined, so that the gear disk 14 can be in the center of the positioning disk 13.

[0041] When the gear disk 14 is processed later, it is rotated by pushing the positioning toothed disc 124. At the same time, the rotating disc 131 on the bottom surface of the hydraulic pump 132 rotates on the top surface of the positioning disc 13. When the rotating disc 131 rotates, it can only rotate on the top surface of the positioning disc 13. At the same time, the gear disk 14 can be positioned in its original position by the limitation of the swing plate 134.

[0042] like Figure 1As shown in Figure 6, a recessed groove 111 is formed on the top surface of the metal forming table 11. Limiting strips 112 are fixedly connected to the inner walls on both sides of the recessed groove 111. A slot 113 is formed on the inner bottom wall of the recessed groove 111. An interlaced limiting cylinder 114 is fixedly connected to the bottom surface of the metal forming table 11 at the middle position. Two bidirectional threaded rods 115 are movably sleeved on the inner wall of the interlaced limiting cylinder 114. The bottom surface of the metal forming table 11 is located at the four edges. A limiting plate 116 is provided on the top, and the two ends of the bidirectional threaded rod 115 extend to the outer surface of the limiting plate 116 respectively. A support base 117 is fixedly connected to the bottom surface of the metal forming table 11 and at the periphery of the staggered limiting cylinder 114. Four sets of hydraulic rods 118 are fixedly installed on the top surface of the support base 117, and the output end of the hydraulic rod 118 extends through the metal forming table 11 to the top surface. The output end of the hydraulic rod 118 is movably connected to the bottom surface of the gear disk 14.

[0043] When the gear disk 14 is positioned on the outer surface of the swing plate 134, it rotates on the outer surface of the limiting plate 116 in conjunction with the bidirectional threaded rod 115, causing the threaded slider 121 to slide in the same direction on the surface of the bidirectional threaded rod 115, and driving the push positioning toothed discs 124 on the outer surface of the two sets of gear positioning frames 12 to engage with the outer surface of the gear disk 14. The two sets of push positioning toothed discs 124 are used to limit the position of the two sides of the gear disk 14. At the same time, the push positioning toothed discs 124 can be rotated so that the teeth on the outer surface of the push positioning toothed discs 124 and the teeth on the surface of the gear disk 14 can be firmly engaged together, thereby limiting the two sides of the gear disk 14.

[0044] At this time, rotating another bidirectional threaded rod 115 causes the other two sets of threaded sliders 121 to move in opposite directions, and causes the push positioning toothed disc 124 to engage with the other two sides of the gear disk 14. This allows the teeth on the surfaces of the four sets of push positioning toothed discs 124 to be firmly attached to the toothed surfaces on the outer surfaces of the gear disk 14, thus achieving the effect of simultaneous positioning on all four sides of the surface of the gear disk 14.

[0045] like Figures 1 to 4 and Figure 9As shown, a threaded slider 121 is fixedly connected to the bottom surface of the gear positioning frame 12. The inner wall of the threaded slider 121 is threadedly and movably sleeved on the outer surface of the bidirectional threaded rod 115. A limit support frame 122 is fixedly connected to the inner wall of the gear positioning frame 12. One end of the limit support frame 122 is movably sleeved on the outer surface of the transmission rod 123. An arc-shaped bonding plate 125 is provided on one side surface of the gear positioning frame 12. The outer surface of the arc-shaped bonding plate 125 is movably overlapped on the outer surface of the gear disk 14. A positioning box a1 is fixedly installed on the top surface of the metal forming table 11 and at one edge position. A hydraulic lifting rod a2 is provided inside the positioning box a1. A transverse moving arm a3 is fixedly connected to the output end of the hydraulic lifting rod a2. A processor a4 is provided on the output end of the transverse moving arm a3.

[0046] After the gear disk 14 is positioned, the hydraulic lifting rod a2 lowers the transverse moving arm a3, causing the machining tool a4 on the outer surface of the transverse moving arm a3 to process the surface of the gear disk 14. At the same time, the machining tool a4 slides back and forth on the surface of the transverse moving arm a3, which can process different transverse positions on the surface of the gear disk 14. Simultaneously, the push positioning toothed disc 124 can be rotated, thereby rotating the gear disk 14 and moving different positions on the bottom of the gear disk 14 to the bottom edge of the machining tool a4 to process the surface of the gear disk 14.

[0047] Working principle: The gear disk 14 is overlapped on the outer surface of the swing plate 134, and the bottom surface of the gear disk 14 is overlapped by the rotating disk 131. At this time, the hydraulic pump 132 lifts the push disk 133. As the push disk 133 rises, it will squeeze and adhere to the inner wall of the swing plate 134, and cause the swing plate 134 to expand outward. The outer surface of the swing plate 134 adheres to the inner wall of the gear disk 14, and the position of the gear disk 14 is defined, so that the gear disk 14 can be in the center of the positioning disk 13.

[0048] When the gear disk 14 is processed later, it is rotated by pushing the positioning toothed disc 124. At the same time, the rotating disc 131 on the bottom surface of the hydraulic pump 132 rotates on the top surface of the positioning disc 13. When the rotating disc 131 rotates, it can only rotate on the top surface of the positioning disc 13. At the same time, under the limitation of the swing plate 134, the gear disk 14 can be positioned in the original position.

[0049] When the gear disk 14 is positioned on the outer surface of the swing plate 134, it rotates on the outer surface of the limiting plate 116 in conjunction with the bidirectional threaded rod 115, causing the threaded slider 121 to slide in the same direction on the surface of the bidirectional threaded rod 115, and driving the push positioning toothed discs 124 on the outer surface of the two sets of gear positioning frames 12 to engage with the outer surface of the gear disk 14. The two sets of push positioning toothed discs 124 are used to limit the position of the two sides of the gear disk 14. At the same time, the push positioning toothed discs 124 can be rotated so that the teeth on the outer surface of the push positioning toothed discs 124 and the teeth on the surface of the gear disk 14 can be firmly engaged together, thereby limiting the two sides of the gear disk 14.

[0050] The gear disk 14 is placed on the top outer surface of the metal forming table 11, and the gear disk 14 is positioned at the center of the top of the metal forming table 11 by the positioning disk 13. At this time, the push positioning toothed disk 124 on the inner wall of the gear positioning frame 12 is engaged with the toothed disk on the outer surface of the gear disk 14, and the toothed disk 14 is positioned by the toothed disk 124. Moreover, the staggered engagement between the toothed disks prevents the gear disk 14 from shaking or shifting in position.

[0051] After the independent positions on the surface of the gear disk 14 are machined, the transmission rod 123 is rotated with the grip, which in turn drives the push positioning toothed disc 124 on the outer surface of the transmission rod 123 to rotate. When the push positioning toothed disc 124 rotates, the teeth on the outer surface of the push positioning toothed disc 124 will drive the teeth on the outer surface of the gear disk 14 to rotate together. During the rotation, the gear disk 14 rotates at the center position on the top of the metal forming table 11. At the same time, the push positioning toothed discs 124 on the other four positions on the outer surface of the gear disk 14 will also rotate together with the rotation of the gear disk 14. At this time, the four push positioning toothed discs 124 on the surface of the gear disk 14 will not cause the gear disk 14 to shift in position without changing the original position of the gear disk 14 or disassembling the surface fixing device of the gear disk 14.

[0052] After the gear disk 14 is positioned, the hydraulic lifting rod a2 lowers the transverse moving arm a3, causing the machining tool a4 on the outer surface of the transverse moving arm a3 to process the surface of the gear disk 14. At the same time, the machining tool a4 slides back and forth on the surface of the transverse moving arm a3, which can process different transverse positions on the surface of the gear disk 14. Simultaneously, the push positioning toothed disc 124 can be rotated, thereby rotating the gear disk 14 and moving different positions on the bottom of the gear disk 14 to the bottom edge of the machining tool a4 to process the surface of the gear disk 14.
