Description

Technical Field

[0001] The invention belongs to the technical field of gear processing, and in particular relates to a gear positioning device in a gear processing machine. Background Art

[0002] Gears are common components in mechanical transmission. They have a set of evenly arranged teeth that are used to mesh with other gears to achieve power transmission, motion conversion or speed change. Gears are divided into internal gears and external gears and are made of metal. In the rough processing stage of gears, the main parts such as the gear shape and gear holes need to be processed first. Gear processing machines are usually used. When processing external gears, the teeth are usually cut first and then the keyways are cut. When cutting teeth, the inner ring of the gear blank is clamped by a fixture, and the gear tooth shape is cut out of the outer ring of the gear blank by a gear processing machine. When cutting the keyway, the outer teeth of the gear are positioned and clamped by a fixture, and the keyway is cut out of the gear by a gear processing machine.

[0003] When processing gears, they are usually first positioned and fixed by a positioning device on a gear processing machine, and then processed. However, gears are divided into external gears and internal gears. When processing external gears, the positioning device on the existing gear processing machine can only position and fix the inner ring of the gear blank so that the gear processing machine can cut the tooth shape on the outer ring of the gear blank. When it is necessary to open a keyway on the external gear, the existing positioning device is not accurate enough in positioning and fixing the external teeth of the external gear, resulting in large processing errors. In addition, the existing positioning device has low functionality and cannot position and clamp external gears and internal gears of different specifications, resulting in low processing efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a gear positioning device in a gear processing machine.

[0005] The technical solution adopted to solve the above technical problems is: a gear positioning device in a gear processing machine, comprising a bottom plate, a retaining ring is fixedly connected to the top of the bottom plate, and a drainage mechanism is installed on the top of the bottom plate;

[0006] A positioning clamping mechanism is installed at the top center of the bottom plate and inside the retaining ring, and a rotating mechanism is installed at the bottom front end of the bottom plate;

[0007] The positioning and clamping mechanism is provided with a first gear.

[0008] A bearing is fixedly installed at the center of the bottom plate, and a drainage hole is opened at the bottom of the bottom plate and inside the retaining ring.

[0009] The above technical solution makes it easy to discharge the coolant and prevents coolant accumulation.

[0010] Furthermore, the drainage mechanism includes a fixing frame fixedly connected to the bottom of the base plate, a drainage funnel is fixedly connected to the center of the fixing frame, a plurality of liquid outlet pipes are fixedly connected to the outer wall of the drainage funnel, and a drainage pipe is fixedly connected to the bottom center of the drainage funnel.

[0011] Through the above technical solution, when processing the gear blank or the first gear, the coolant used in the processing falls into the retaining ring, flows into the drainage funnel through multiple outlet pipes, and is finally discharged to the outside through the drainage pipe, thereby preventing the coolant from accumulating and affecting the processing.

[0012] Furthermore, the top ends of the plurality of liquid outlet pipes are aligned with the corresponding liquid discharge holes.

[0013] Through the above technical solution, the coolant on the top of the bottom plate is transported to the corresponding liquid outlet pipes through the multiple liquid discharge holes, so the coolant can be quickly discharged.

[0014] Furthermore, the positioning and clamping mechanism includes a chassis arranged at the top center of the bottom plate, a connecting pipe is fixedly connected to the bottom center of the chassis, a disc body is fixedly installed on the top of the chassis, a plurality of first slide grooves are opened on the top of the disc body, an annular groove is opened in the center of the disc body, a spiral disc is arranged in the disc body, a plurality of bevel teeth are meshed on the spiral disc, a plurality of first slide grooves are slidably connected with positioning blocks, a top plate is fixedly installed on the top of the disc body, a second slide groove is opened on the top of a plurality of the positioning blocks, a screw rod is rotatably installed in a plurality of the positioning blocks, and a plurality of The outer ends of the screw rods are fixedly connected with adjusting heads, a plurality of the screw rods are installed with nut seats, a plurality of the tops of the nut seats are fixedly connected with connecting seats, a plurality of the tops of the second slide grooves are installed with accordion protective covers to prevent dust from entering the second slide grooves, a plurality of the top outer ends of the connecting seats are fixedly installed with first chucks, a plurality of the top inner ends of the connecting seats are fixedly installed with second chucks, a plurality of the tops of the second chucks are fixedly connected with fixing seats, a plurality of the fixing seats are threadedly connected with threaded rods, and a plurality of the bottom ends of the threaded rods are fixedly connected with splints.

[0015] Through the above technical scheme, when it is necessary to process into the first gear shape, the tooth shape is cut on the outer wall of the gear blank, and the positions of multiple connecting seats are first adjusted to ensure that the multiple first chucks can tighten the inner ring of the gear blank, and the multiple adjusting heads are rotated respectively, so that the rotation of the adjusting heads drives the screw rods connected thereto to rotate, thereby driving the corresponding nut seats to move, so that the multiple connecting seats are adjusted to the specified positions, and the gear blank is placed on the top of the multiple connecting seats, and one of the adjusting shafts is rotated to rotate the bevel teeth connected thereto, so that the rotation of the bevel teeth drives the meshing spiral disk to rotate, so that the spiral disk drives the multiple positioning blocks to move toward the outer end, thereby driving the corresponding first chucks to move toward the outer end, so that the multiple first chucks can move toward the outer end. A chuck supports the inner ring of the gear blank outward to achieve positioning and clamping of the gear blank, and the gear processing machine can cut the outer wall of the gear blank to process it into the first gear shape; when it needs to be processed into the second gear shape, a keyway is opened for the first gear, and the positions of the multiple connecting seats are adjusted first to ensure that the second chucks on the multiple connecting seats can clamp the first gear, and one of the adjustment shafts is rotated to move the multiple positioning blocks toward the outer end and adjust them to the specified position, and then the multiple adjustment heads are rotated respectively according to the same principle to adjust the multiple connecting seats to the specified position, and then the processed first gear is placed on the top of the multiple connecting seats, and one of the adjustment shafts is rotated according to the same principle to move the multiple positioning blocks toward the inner end. The second chuck is fitted with the outer teeth of the first gear to achieve positioning and clamping. Since the outer teeth of the first gear are irregular in shape, the multiple second chucks cannot contact the outer teeth of the first gear well, resulting in uneven clamping force. Therefore, the multiple threaded rods are rotated to drive the corresponding clamping plates to fit with the top of the first gear to further clamp and fix the first gear. The gear processing machine can then process the inner ring of the first gear into the shape of the second gear. When it is necessary to process it into an internal gear, the tooth shape is cut out on the inner wall of the gear blank. The same principle is used to first adjust the positions of the multiple connecting seats to ensure that the multiple second chucks can clamp the outer wall of the gear blank. At this time, the gear blank is placed on the multiple connecting seats. One of the adjusting shafts is rotated to make the multiple positioning blocks move inward, so that the multiple second chucks are fitted with the outer wall of the gear blank to achieve positioning and clamping, and then the multiple threaded rods are rotated according to the same principle to further fix the gear blank through multiple clamping plates. Finally, the gear blank is processed into the shape of an internal gear through a gear processing machine. This mechanism can position gear blanks of different specifications, and can position and clamp the inner ring or outer wall of the gear blank to process it into a first gear or an internal gear. It has strong functionality and can also position the already processed first gear, thereby facilitating the keyway opening thereof. There is no need to put the processed first gear into other positioning mechanisms for positioning, which greatly improves the processing efficiency.

[0016] Furthermore, the top end of the outer wall of the connecting tube is fixedly connected to the inner wall of the bearing, and the connecting tube is inserted into the drainage funnel.

[0017] Through the above technical solution, when the keyway is opened on the first gear, the transported coolant flows to the connecting pipe, and then flows to the drainage funnel through the connecting pipe.

[0018] Furthermore, the centers of the plurality of bevel teeth are fixedly connected with adjustment shafts, and the plurality of adjustment shafts are rotationally connected to the disc body.

[0019] Through the above technical solution, when adjusting the positions of multiple positioning blocks, the staff rotates one of the adjustment shafts using a four-corner wrench, thereby driving the bevel gear connected thereto to rotate, thereby driving the spiral disk to rotate, so that the spiral disk drives the multiple positioning blocks to move.

[0020] Furthermore, a bevel gear ring is provided at the bottom of the spiral disk, the spiral disk is slidably connected to the annular groove, the bottoms of the multiple positioning blocks are fixedly connected with arc teeth, the multiple positioning blocks are respectively engaged with the bevel gear ring through corresponding arc teeth, and the tops of the multiple positioning blocks are provided with scales.

[0021] Through the above technical solution, when the spiral disk rotates, it slides in the annular groove to achieve a limiting effect and improve the rotation stability of the spiral disk.

[0022] Furthermore, one side of the outer wall of each of the plurality of connection seats is provided with a slot, and each of the plurality of connection seats is fixedly connected with a pointer at a position corresponding to the slot.

[0023] Through the above technical solution, scales and pointers are provided, so that the staff can accurately adjust multiple connecting seats to the specified positions according to the specifications of the gear blank, ensuring that the first chuck and the second chuck can clamp the inner ring or outer wall of the gear blank, thereby greatly improving the accuracy of the positioning device.

[0024] Furthermore, the rotating mechanism includes a driving gear ring fixedly connected to the center of the outer wall of the connecting tube, the bottom front end of the base plate is fixedly connected to a mounting bracket, the bottom of the mounting bracket is fixedly installed with a motor, the outer wall of the motor output shaft is fixedly connected to a driving gear, and the driving gear is meshed with the driving gear ring.

[0025] Through the above technical solution, when the positioning and clamping mechanism needs to rotate, the motor is started so that the motor drives the driving gear to rotate through the output shaft, and the driving gear drives the driving gear ring to rotate, thereby driving the connecting pipe to rotate, thereby driving the entire positioning and clamping mechanism to rotate, and then driving the gear blank to rotate, which is convenient for the processing of the positioning and clamping gear blank.

[0026] The beneficial effects of the present invention are as follows: (1) The present invention designs a positioning and clamping mechanism, which can position gear blanks of different specifications and can position and clamp the inner ring or outer wall of the gear blank to process it into an external gear or an internal gear.

The positioning clamping mechanism 4 includes a chassis 401 arranged at the top center of the bottom plate 1, a connecting pipe 402 is fixedly connected to the bottom center of the chassis 401, a disc body 403 is fixedly installed on the top of the chassis 401, a plurality of first slide grooves 404 are opened on the top of the disc body 403, an annular groove 405 is opened in the center of the disc body 403, a spiral disc 406 is arranged in the disc body 403, a plurality of bevel teeth 407 are meshed on the spiral disc 406, a plurality of first slide grooves 404 are all slidably connected with positioning blocks 408, and the top of the disc body 403 is fixed. A top plate 409 is fixedly installed, and a second slide groove 410 is opened on the top of each of the positioning blocks 408. A screw rod 411 is rotatably installed in each of the positioning blocks 408. The outer ends of each of the screw rods 411 are fixedly connected with an adjusting head 412. Nut seats 413 are installed on each of the screw rods 411. The tops of each of the nut seats 413 are fixedly connected with a connecting seat 414. An accordion protective cover 415 is installed on the top of each of the second slide grooves 410 to prevent dust from entering the second slide grooves 410. A first chuck 416 is fixedly installed on the outer ends of the tops of each of the connecting seats 414. The ends of the plurality of second clamps 417 are fixedly installed with second clamps 417, the tops of the plurality of second clamps 417 are fixedly connected with fixed seats 418, the plurality of fixed seats 418 are threadedly connected with threaded rods 419, and the bottom ends of the plurality of threaded rods 419 are fixedly connected with clamps 420. When it is necessary to process into the shape of the first gear 6 (cutting the tooth shape on the outer wall of the gear blank), first adjust the positions of the plurality of connecting seats 414 to ensure that the plurality of first clamps 416 can tighten the inner ring of the gear blank, and respectively rotate the plurality of adjusting heads 412, so that the rotation of the adjusting heads 412 drives the screw rod 411 connected thereto to rotate, thereby driving the corresponding nut seat 41 3, thereby adjusting the multiple connecting seats 414 to the specified position, placing the gear blank on the top of the multiple connecting seats 414, rotating one of the adjusting shafts 4071, thereby rotating the bevel gear 407 connected thereto, so that the bevel gear 407 rotates to drive the meshing spiral disk 406 to rotate, so that the spiral disk 406 drives the multiple positioning blocks 408 to move toward the outer end, thereby driving the corresponding first clamping heads 416 to move toward the outer end, so that the multiple first clamping heads 416 outwardly support the inner ring of the gear blank to achieve positioning and clamping of the gear blank, and the gear processing machine can cut the outer wall of the gear blank to process it into the shape of the first gear 6;When it is necessary to process into the shape of the second gear 7 (opening a keyway for the first gear 6), first adjust the positions of the plurality of connecting seats 414 to ensure that the second chucks 417 on the plurality of connecting seats 414 can clamp the first gear 6, rotate one of the adjusting shafts 4071, move the plurality of positioning blocks 408 toward the outer end, adjust to the specified position, and then rotate the plurality of adjusting heads 412 respectively based on the same principle so that the plurality of connecting seats 414 are adjusted to the specified position, and then place the processed first gear 6 on the top of the plurality of connecting seats 414, rotate one of the adjusting shafts 4071 based on the same principle so that the plurality of positioning blocks 408 are moved toward the inner end so that the plurality of second chucks 417 are fitted with the outer teeth of the first gear 6 to achieve positioning and clamping. Since the outer teeth of the first gear 6 are irregular in shape, the plurality of second chucks 417 cannot contact the outer teeth of the first gear 6 well, resulting in uneven clamping force. Therefore, the plurality of threaded rods 419 are rotated to drive the corresponding clamping plates 420 to fit with the top of the first gear 6, and further clamp and fix the first gear 6. The gear processing machine can then process the first gear 6 The inner ring of the gear 6 is processed into the shape of the second gear 7; when it needs to be processed into the inner gear 8 (cutting the tooth shape on the inner wall of the gear blank), the positions of the multiple connecting seats 414 are adjusted according to the same principle to ensure that the multiple second chucks 417 can clamp the outer wall of the gear blank. At this time, the gear blank is placed on the multiple connecting seats 414, and one of the adjustment shafts 4071 is rotated according to the same principle to move the multiple positioning blocks 408 to the inner end, so that the multiple second chucks 417 fit the outer wall of the gear blank to achieve positioning and clamping. Then, the multiple threaded rods 419 are rotated according to the same principle to further fix the gear blank through the multiple clamping plates 420. Finally, the gear blank is processed into the shape of the inner gear 8 by the gear processing machine.

[0045] like Figure 1-Figure 14As shown, the top of the outer wall of the connecting pipe 402 is fixedly connected to the inner wall of the bearing 11, and the connecting pipe 402 is inserted into the drainage funnel 302. When the key groove is opened on the first gear 6, the transported coolant flows to the connecting pipe 402, and then flows to the drainage funnel 302 through the connecting pipe 402. The centers of the multiple bevel teeth 407 are fixedly connected with the adjusting shaft 4071, and the multiple adjusting shafts 4071 are rotatably connected to the disk body 403. When adjusting the positions of the multiple positioning blocks 408, the staff rotates one of the adjusting shafts 4071 with a four-angle wrench, thereby driving the bevel teeth 407 connected thereto to rotate, thereby driving the spiral disk 406 to rotate, so that the spiral disk 406 drives the multiple positioning blocks 408 to move, and the bottom of the spiral disk 406 is provided with a bevel gear ring 4061, and the spiral disk 406 is slidably connected to the annular groove 405. The bottom is fixedly connected with arc teeth 4081, and multiple positioning blocks 408 are respectively meshed with the bevel gear ring 4061 through the corresponding arc teeth 4081.

Scales 4082 and pointers 4142 are provided, so that the staff can accurately adjust the multiple connecting seats 414 to the specified position according to the specifications of the gear blank, ensuring that the first chuck 416 and the second chuck 417 can clamp the inner ring or outer wall of the gear blank, thereby greatly improving the accuracy of the positioning device.

[0046] like Figure 1-Figure 4 As shown, a rotating mechanism 5 is installed at the bottom front end of the base plate 1, and a first gear 6 is provided on the positioning and clamping mechanism 4. The rotating mechanism 5 includes a driving gear ring 501 fixedly connected to the center of the outer wall of the connecting tube 402. A mounting frame 502 is fixedly connected to the bottom front end of the base plate 1, and a motor 503 is fixedly installed at the bottom of the mounting frame 502. A driving gear 504 is fixedly connected to the outer wall of the output shaft of the motor 503, and the driving gear 504 is meshed with the driving gear ring 501. When the positioning and clamping mechanism 4 needs to be rotated, the motor 503 is started, so that the motor 503 drives the driving gear 504 to rotate through the output shaft, so that the driving gear 504 drives the driving gear ring 501 to rotate, thereby driving the connecting tube 402 to rotate, thereby driving the entire positioning and clamping mechanism 4 to rotate, and then driving the gear blank to rotate, so as to facilitate the processing of the positioning and clamping gear blank.

[0047] The working principle of this embodiment is as follows: when the first gear 6 needs to be processed (the tooth shape is cut on the outer wall of the gear blank), the positions of the multiple connecting seats 414 need to be adjusted according to the size of the gear blank to ensure that the multiple first chucks 416 can hold the inner ring of the gear blank tightly, and the multiple adjusting heads 412 are rotated respectively, so that the adjusting heads 412 rotate to drive the screw rod 411 connected thereto to rotate, thereby driving the corresponding nut seat 413 to move, so that the multiple connecting seats 414 are adjusted to the specified position. When the connecting seat 414 moves, the staff can adjust the position according to the scale 4082 value aligned with the pointer 4142 , adjust the multiple connecting seats 414 to the precise position, place the gear blank on the top of the multiple connecting seats 414, rotate one of the adjusting shafts 4071, thereby rotating the bevel gear 407 connected thereto, so that the bevel gear 407 rotates to drive the meshing spiral disk 406 to rotate, so that the spiral disk 406 drives the multiple positioning blocks 408 to move toward the outer end, thereby driving the corresponding first chucks 416 to move toward the outer end, so that the multiple first chucks 416 outwardly support the inner ring of the gear blank to achieve positioning and clamping of the gear blank, and the gear processing machine can cut the outer wall of the gear blank to process it into the shape of the first gear 6;

[0048] When it is necessary to process into the shape of the second gear 7 (opening a keyway for the first gear 6), first adjust the positions of the plurality of connection seats 414 to ensure that the second clamping heads 417 on the plurality of connection seats 414 can clamp the first gear 6, rotate one of the adjustment shafts 4071, move the plurality of positioning blocks 408 toward the outer end, adjust to the specified position, and then rotate the plurality of adjustment heads 412 respectively according to the same principle, so that the plurality of connection seats 414 are adjusted to the specified position, and then place the processed first gear 6 on the top of the plurality of connection seats 414, and rotate one of the adjustment shafts 4071 according to the same principle. 71, so that the multiple positioning blocks 408 move inward, so that the multiple second clamps 417 fit with the outer teeth of the first gear 6 to achieve positioning and clamping. Since the outer teeth of the first gear 6 are irregular in shape, the multiple second clamps 417 cannot contact the outer teeth of the first gear 6 well, resulting in uneven clamping force. Therefore, the multiple threaded rods 419 are rotated to drive the corresponding clamping plates 420 to fit with the top of the first gear 6, and further clamp the first gear 6. The gear processing machine can process the inner ring of the first gear 6 into the shape of the second gear 7;

[0049] When it is necessary to process into an internal gear 8 (cutting a tooth shape on the inner wall of the gear blank), the positions of the multiple connecting seats 414 are adjusted according to the same principle to ensure that the multiple second chucks 417 can clamp the outer wall of the gear blank. At this time, the gear blank is placed on the multiple connecting seats 414, and one of the adjustment shafts 4071 is rotated according to the same principle to move the multiple positioning blocks 408 toward the inner end so that the multiple second chucks 417 fit the outer wall of the gear blank to achieve positioning and clamping. Then, the multiple threaded rods 419 are rotated according to the same principle to further fix the gear blank through the multiple clamping plates 420, and finally the gear blank is processed into the shape of an internal gear 8 by the gear processing machine;

[0050] When processing the gear blank or the first gear 6, the motor 503 is started, so that the motor 503 drives the driving gear 504 to rotate through the output shaft, so that the driving gear 504 drives the driving gear ring 501 to rotate, thereby driving the connecting tube 402 to rotate, thereby driving the entire positioning clamping mechanism 4 to rotate, and then driving the gear blank to rotate, so as to facilitate the processing of the gear blank;

[0051] When processing the gear blank or the first gear 6 , the input coolant flows to the drain funnel 302 through the connecting pipe 402 , and is simultaneously transported to the corresponding outlet pipe 303 through a plurality of drain holes 12 , and then flows to the drain funnel 302 , and finally is discharged to the outside through the drain pipe 304 .
