Description

Technical Field

[0001] This utility model belongs to the field of gear shaping cutter modification technology, specifically relating to a positioning device adapted to standard gear shaping cutter modification. Background Technology

[0002] Gear shapers are commonly used tools in the gear machining field, widely used in the machining of various types of gears such as spur gears, helical gears, and internal gears. In actual production, due to changes in machining requirements, it is often necessary to modify standard gear shapers, such as adjusting tooth profile parameters and re-grinding the cutting edge angle. During the modification process, the positioning accuracy of the gear shaper directly determines the machining performance of the tool after modification. If the positioning deviation is too large, it will cause problems such as tooth profile error and tooth direction error in the gears machined by the modified gear shaper, which will seriously affect the gear transmission accuracy and service life.

[0003] In existing technologies, the positioning methods for modifying standard gear shapers mostly adopt traditional three-jaw chuck clamping or simple tooling positioning. While three-jaw chuck clamping is convenient to operate, it can only clamp and fix the outer periphery of the gear shaper, and cannot accurately position key references such as the end face and axis of the gear shaper. Moreover, uneven force during clamping can easily cause slight deformation of the gear shaper, affecting the accuracy of the modification. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device adapted for modifying standard gear shaping cutters, so as to solve the problem mentioned in the background art that the positioning method for modifying standard gear shaping cutters mostly adopts traditional three-jaw chuck clamping positioning or simple tooling positioning. Among them, although the three-jaw chuck clamping positioning is convenient to operate, it can only achieve clamping and fixing of the outer periphery of the gear shaping cutter, and cannot accurately position the end face, axis and other key references of the gear shaping cutter. Moreover, during the clamping process, uneven force can easily cause slight deformation of the gear shaping cutter, affecting the accuracy of the modification.

[0005] To achieve the above objectives, this utility model provides the following technical solution: including a machining base and a gear shaping cutter body;

[0006] The upper surface of the machining base is provided with an arc-shaped groove, and a support rod is installed on the right side of the inner wall of the groove. The main body of the gear hobbing cutter is sleeved on the support rod.

[0007] A threaded rod is threadedly installed on the left side of the machining seat. One end of the threaded rod is threaded through and extends into a groove and is rotatably mounted with a pressing plate. The other end of the threaded rod is mounted with an operating plate, and a control lever is mounted on the operating plate.

[0008] The pallet is located below the left end of the support rod. An L-shaped base plate is installed on the lower surface of the extrusion plate, and a support plate is installed on the upper surface of the horizontal part of the base plate. The top of the support plate is fixedly connected to the pallet.

[0009] The tooth-shaping cutter body has three fixing rods 2 and 1 on its left and right sides, respectively. The fixing rod 1 is fixedly connected to the inner wall of the groove, and the fixing rod 2 is fixedly connected to the extrusion plate. Both the fixing rod 1 and the fixing rod 2 are equipped with anti-slip components.

[0010] The above solution utilizes an arc-shaped groove to achieve initial fitting and positioning of the gear shaping cutter body. This is complemented by a support rod for support, and a threaded rod drives the extrusion plate to apply pressure from the left side. Simultaneously, a support plate supports the left end of the support rod from below, forming a triple-fixed structure of side pressure, bottom support, and fitting. This effectively prevents the gear shaping cutter from shifting or shaking during the modification process, ensuring machining accuracy. Fixing rod one and fixing rod two provide auxiliary positioning from the left and right sides of the gear shaping cutter body, respectively, and their spacing can be adjusted as the extrusion plate moves. This adapts to the modification needs of standard gear shaping cutters of different specifications, eliminating the need for frequent replacement of positioning components. The design of the operating panel and lever makes adjusting the extrusion force by rotating the threaded rod easier, reducing the operator's workload. The anti-slip components on fixing rod one and fixing rod two increase the friction with the gear shaping cutter body, further preventing relative slippage of the gear shaping cutter during force or rotational processing. This compensates for the shortcomings of simple mechanical fixing and improves overall positioning reliability.

[0011] In a preferred embodiment, the anti-slip component includes two sets of rubber pads, with two rubber pads in each set. The two sets of rubber pads are respectively installed on fixing rod one and fixing rod two, and the rubber pads are in close contact with the tooth-shaping cutter body.

[0012] By adopting the above solution, a rubber pad is set. The rubber material itself has a high coefficient of friction, which can directly and tightly fit with the main body of the gear shaping cutter, effectively preventing slippage. At the same time, the rubber pad is inexpensive and easy to replace, without the need for complex structural design. While ensuring anti-slip performance, the manufacturing cost of the device is controlled. The rubber material is soft and will not cause hard scratches or indentations when in contact with the main body of the gear shaping cutter, avoiding damage to the cutting edge or surface precision of the gear shaping cutter during the positioning and fixing process, and ensuring the performance of the gear shaping cutter after modification.

[0013] In a preferred embodiment, two telescopic rods are installed on the left side of the inner wall of the groove. The two telescopic rods are located on the front and rear sides of the threaded rod, respectively, and the telescopic shafts of the telescopic rods are fixedly connected to the extrusion plate.

[0014] By adopting the above solution, a telescopic rod is set up. The telescopic rod and the threaded rod are set parallel to each other and located on the front and rear sides respectively. This provides precise guidance for the movement of the extrusion plate, avoids the extrusion plate from rotating, ensures that the extrusion plate always maintains perpendicular pressure with the gear cutter body, guarantees positioning accuracy, reduces jamming between the threaded rod and the threaded hole of the machining seat, and makes it smoother for operators to adjust the extrusion force, thus improving the operating experience.

[0015] In a preferred embodiment, the front side of the processing seat is provided with a collection groove, which is connected to the bottom end of the groove. A collection frame with an open upper surface is provided in the collection groove, and a U-shaped handle is installed on the front side of the collection frame.

[0016] By adopting the above solution, a collection frame is set up, and the collection groove is connected to the bottom of the groove. Metal shavings and waste generated during the tool modification process can slide directly from the groove into the collection frame, avoiding waste from scattering on the surface of the machining seat or workbench, reducing cleaning workload, keeping the machining environment orderly, and operators can quickly pull out the collection frame to dump the waste by simply using the U-shaped handle without disassembling other parts, thus improving waste cleaning efficiency and reducing processing interruption time.

[0017] In a preferred embodiment, two rotating columns are rotatably mounted on the front side of the processing base, and an intercepting plate is mounted on the rotating columns. The intercepting plate is located on the front side of the collection frame.

[0018] By adopting the above solution, an interceptor plate is installed on the front side of the processing base via a rotating column. The interceptor plate can be rotated to the front of the collection frame to form a blockage, preventing the collection frame from accidentally sliding out of the collection tank when the device moves, vibrates, or is accidentally touched by the operator, thus preventing waste from spilling and not increasing the complexity of operation.

[0019] In a preferred embodiment, connecting plates are slidably mounted on both the left and right sides of the upper surface of the processing base via sliding components, and brush bristles are mounted on the lower surface of the connecting plates.

[0020] By adopting the above solution, the brush bristles on the lower surface of the connecting plate can slide with the connecting plate to clean the dust and small waste on the upper surface of the machining seat. This prevents impurities from adhering to the surface of the machining seat and affecting the positioning and fit of the gear cutter, or causing the sliding component to jam. This ensures positioning and adjustment accuracy, eliminates the need for special downtime cleaning, reduces extra time consumption in the processing process, and improves overall work efficiency.

[0021] In a preferred embodiment, the sliding assembly includes two U-shaped slide rods, which are respectively installed on the front and rear sides of the upper surface of the processing base. Two sliding plates are slidably mounted on the slide rods, and two connecting plates are respectively installed on the upper surfaces of the two sliding plates on the same side.

[0022] By adopting the above solution, a sliding rod and a sliding plate are set. The sliding rod is fixed on the front and rear sides of the upper surface of the processing base. When the sliding plate slides on the sliding rod, the U-shaped structure of the sliding rod can limit the vertical displacement of the sliding plate, ensuring that the connecting plate always slides smoothly in the lateral direction, avoiding the brush bristles from shaking up and down during the cleaning process, ensuring the cleaning effect, and not affecting the overall use of the device.

[0023] In a preferred embodiment, side plates are installed on opposite sides of the two connecting plates, and positioning bolts are threaded onto the side plates, with the bottom end of the positioning bolts in close contact with the machining seat.

[0024] By adopting the above solution, by setting positioning bolts and side plates, when the bottom end of the positioning bolts is in close contact with the processing seat, the position of the connecting plate can be fixed by friction. This prevents the connecting plate from sliding on its own and causing the bristles to shift when the device vibrates or the operator accidentally touches it. This ensures that the bristles can accurately act on the target area during cleaning, or that the connecting plate remains fixed when cleaning is not required, without affecting the processing operation.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This positioning device for standard gear shaping cutter conversion uses an arc-shaped groove to initially fit and position the gear shaping cutter body. It works in conjunction with a support rod for support, and then uses a threaded rod to drive the extrusion plate to apply pressure from the left side. Simultaneously, a support plate supports the left end of the support rod from below, forming a triple-fixing structure of side pressure, bottom support, and fitting. This effectively prevents offset and shaking during gear shaping cutter conversion, ensuring processing accuracy. Fixing rod one and fixing rod two provide auxiliary positioning from the left and right sides of the gear shaping cutter body, and their spacing can be adjusted as the extrusion plate moves. This adapts to the conversion needs of standard gear shaping cutters of different specifications, eliminating the need for frequent replacement of positioning components. The design of the operating panel and lever makes adjusting the extrusion force by rotating the threaded rod easier, reducing operator workload. The anti-slip components on fixing rod one and fixing rod two increase friction with the gear shaping cutter body, further preventing relative sliding of the gear shaping cutter during force or rotation processing, compensating for the shortcomings of simple mechanical fixing and improving overall positioning reliability.

[0027] The positioning device for this standard gear shaping cutter modification uses a rubber pad. The rubber material itself has a high coefficient of friction, which allows it to directly and tightly fit the gear shaping cutter body, effectively preventing slippage. At the same time, the rubber pad is inexpensive and easy to replace, eliminating the need for complex structural designs. This ensures anti-slip performance while controlling the manufacturing cost of the device. The rubber material is soft and will not cause hard scratches or indentations when in contact with the gear shaping cutter body, avoiding damage to the cutting edge or surface precision of the gear shaping cutter during the positioning and fixing process, and ensuring the performance of the gear shaping cutter after modification.

[0032] Please see Figs. 1-3 This utility model provides a positioning device for adapting to the modification of standard gear shaping cutters, including a processing base 1 and a gear shaping cutter body 8;

[0033] The upper surface of the machining base 1 is provided with an arc-shaped groove, and a support rod 5 is installed on the right side of the inner wall of the groove. The gear cutter body 8 is sleeved on the support rod 5.

[0034] The threaded rod 23 is threadedly installed on the left side of the machining seat 1. One end of the threaded rod 23 is threaded through and extends into the groove and is rotatably mounted with the extrusion plate 2. The other end of the threaded rod 23 is mounted with the operation plate 3, and the operation lever 4 is mounted on the operation plate 3.

[0035] The pallet 11 is located below the left end of the support rod 5. An L-shaped base plate 9 is installed on the lower surface of the extrusion plate 2. A support plate 10 is installed on the upper surface of the horizontal part of the base plate 9. The top of the support plate 10 is fixedly connected to the pallet 11.

[0036] Among them, three fixing rods 7 and fixing rod 6 are respectively provided on the left and right sides of the gear cutter body 8. Fixing rod 6 is fixedly connected to the inner wall of the groove, and fixing rod 7 is fixedly connected to the extrusion plate 2. Anti-slip components are provided on fixing rod 6 and fixing rod 7.

[0037] Using the above scheme, the initial fitting and positioning of the gear shaping cutter body 8 is achieved through the arc-shaped groove, which is supported by the support rod 5. Then, the threaded rod 23 drives the extrusion plate 2 to apply pressure from the left side. At the same time, the support plate 11 supports the left end of the support rod 5 from below, forming a triple fixing structure of side pressure, bottom support, and fitting. This effectively avoids the gear shaping cutter from shifting or shaking during the modification process, ensuring processing accuracy. The first fixing rod 6 and the second fixing rod 7 respectively provide auxiliary positioning from the left and right sides of the gear shaping cutter body 8, and the spacing can be adjusted as the extrusion plate 2 moves. This can adapt to the modification needs of standard gear shaping cutters of different specifications without the need for frequent replacement of positioning components. The design of the operating plate 3 and the control lever 4 makes it easier to adjust the extrusion force by rotating the threaded rod 23, reducing the workload of the operator. The anti-slip components on the first fixing rod 6 and the second fixing rod 7 can increase the friction with the gear shaping cutter body 8, further preventing relative sliding of the gear shaping cutter when under force or rotating during processing. This makes up for the shortcomings of simple mechanical fixing and improves the overall positioning reliability.

[0038] In a preferred embodiment, the anti-slip component includes two sets of rubber pads 13, with two rubber pads in each set. The two sets of rubber pads 13 are respectively installed on the first fixing rod 6 and the second fixing rod 7, and the rubber pads 13 are in close contact with the tooth cutter body 8.

[0039] By adopting the above solution, a rubber pad 13 is set. The rubber material itself has a high coefficient of friction, which can directly and tightly fit with the gear shaping cutter body 8, effectively preventing slippage. At the same time, the rubber pad 13 is inexpensive and easy to replace, without the need for complex structural design. While ensuring anti-slip performance, the manufacturing cost of the device is controlled. The rubber material is soft and will not cause hard scratches or indentations when in contact with the gear shaping cutter body 8, avoiding damage to the cutting edge or surface accuracy of the gear shaping cutter during the positioning and fixing process, and ensuring the performance of the gear shaping cutter after modification.

[0040] In a preferred embodiment, two telescopic rods 12 are installed on the left side of the inner wall of the groove. The two telescopic rods 12 are located on the front and rear sides of the threaded rod 23, respectively, and the telescopic shafts of the telescopic rods 12 are fixedly connected to the extrusion plate 2.

[0041] By adopting the above solution, the telescopic rod 12 is set parallel to the threaded rod 23 and located on the front and rear sides respectively. This provides precise guidance for the movement of the extrusion plate 2, avoids the extrusion plate 2 from rotating, ensures that the extrusion plate 2 always maintains perpendicular pressure with the gear cutter body 8, guarantees positioning accuracy, reduces jamming between the threaded rod 23 and the threaded hole of the processing seat 1, and makes it smoother for operators to adjust the extrusion force, thus improving the operating experience.

[0042] In a preferred embodiment, the front side of the processing base 1 is provided with a collection groove, which is connected to the bottom end of the groove. A collection frame 19 with an open upper surface is provided in the collection groove, and a U-shaped handle 22 is installed on the front side of the collection frame 19.

[0043] By adopting the above solution, by setting up a collection frame 19 and connecting the collection groove with the bottom of the groove, metal shavings and waste generated during the tool modification process can slide directly from the groove into the collection frame 19, avoiding waste from scattering on the surface of the processing seat 1 or the workbench, reducing cleaning workload, keeping the processing environment orderly, and operators can quickly pull out the collection frame 19 to dump the waste by simply using the U-shaped handle 22 without disassembling other parts, thus improving waste cleaning efficiency and reducing processing interruption time.

[0044] In a preferred embodiment, two rotating columns 20 are rotatably mounted on the front side of the processing base 1, and an intercepting plate 21 is mounted on the rotating columns 20. The intercepting plate 21 is located on the front side of the collection frame 19.

[0045] By adopting the above solution, by setting up an interceptor plate 21, which is installed on the front side of the processing base 1 via a rotating column 20, the interceptor plate 21 can be rotated to the front side of the collection frame 19 to form a blockage, preventing the collection frame 19 from accidentally sliding out of the collection tank when the device moves, vibrates, or is accidentally touched by the operator, thus preventing waste from spilling and not increasing the complexity of operation.

[0046] In a preferred embodiment, connecting plates 18 are slidably mounted on both the left and right sides of the upper surface of the processing base 1 via sliding components, and brush bristles are mounted on the lower surface of the connecting plates 18.

[0047] By adopting the above solution, by setting the connecting plate 18 and the brush bristles, the brush bristles on the lower surface of the connecting plate 18 can slide with the connecting plate 18 to clean the dust and small waste on the upper surface of the processing seat 1, so as to avoid impurities adhering to the surface of the processing seat 1 and affecting the positioning and fit of the gear cutter, or causing the sliding component to jam, ensuring positioning and adjustment accuracy, eliminating the need for special shutdown cleaning, reducing the extra time consumption in the processing process, and improving the overall work efficiency.

[0048] In a preferred embodiment, the sliding assembly includes two U-shaped slide rods 16, which are respectively installed on the front and rear sides of the upper surface of the processing base 1. Two slide plates 17 are slidably mounted on the slide rods 16, and two connecting plates 18 are respectively installed on the upper surfaces of the two slide plates 17 on the same side.

[0049] By adopting the above solution, by setting up a slide bar 16 and a slide plate 17, the slide bar 16 is fixed on the front and rear sides of the upper surface of the processing base 1. When the slide plate 17 slides on the slide bar 16, the U-shaped structure of the slide bar 16 can limit the vertical displacement of the slide plate 17, ensuring that the connecting plate 18 always slides smoothly in the lateral direction, avoiding the brush bristles from shaking up and down during the cleaning process, ensuring the cleaning effect, and not affecting the overall use of the device.

[0050] In a preferred embodiment, side plates 14 are installed on opposite sides of the two connecting plates 18, and positioning bolts 15 are threaded onto the side plates 14, with the bottom end of the positioning bolts 15 in close contact with the machining seat 1.

[0051] By adopting the above solution, by setting the positioning bolt 15 and the side plate 14, when the bottom end of the positioning bolt 15 is in close contact with the processing seat 1, the position of the connecting plate 18 can be fixed by friction. This prevents the connecting plate 18 from sliding on its own and causing the bristles to shift when the device vibrates or the operator accidentally touches it. This ensures that the bristles can accurately act on the target area during cleaning, or that the connecting plate 18 remains fixed when cleaning is not required, without affecting the processing operation.

[0052] In use, rotating the control lever 4 drives the operation plate 3 to rotate, and the operation plate 3 drives the threaded rod 23 to rotate. Combined with the threaded connection between the threaded rod 23 and the processing seat 1, the rotation of the threaded rod 23 drives the extrusion plate 2 to move. The movement of the extrusion plate 2 drives the fixed rod 7, the base plate 9 and the support plate 10 to move. At this time, the support plate 11 gradually moves to the bottom of the support rod 5 along with the movement of the support plate 10. One end of the fixed rod 7 abuts against the gear shaping cutter body 8 and drives the gear shaping cutter body 8 to move and abut against the fixed rod 6. The rubber pad 13 on the fixed rod 6 and the fixed rod 7 positions and fixes the gear shaping cutter body 8. Then, stop rotating the threaded rod 23, and the gear shaping cutter body 8 can be modified.

[0053] Clean the surface of the machining seat 1: Loosen the positioning bolt 15. At this time, the bottom end of the positioning bolt 15 gradually moves away from the machining seat 1. Then move the connecting plate 18. The movement of the connecting plate 18 drives the brush to move. The movement of the brush cleans the debris on the surface of the machining seat 1 and pushes it into the groove.

[0054] Remove the collection box 19: Rotate the interceptor plate 21, which changes from a vertical state to a horizontal state. Then move the collection box 19 by the handle 22. The collection box 19 gradually extends out of the collection slot, and then the collection slot can be removed to clean the debris inside.
