Description

Technical Field

[0001] This invention relates to the field of worm gear processing equipment, specifically a gear hobbing device for worm gear reducer motor components. Background Technology

[0002] As a core transmission component inside a geared motor, worm gears are widely used in the power transmission structure of various small and medium-sized geared motors due to their advantages such as smooth transmission, strong load-bearing capacity, and wide transmission ratio range. In the actual production and processing of worm gears, hobbing is a key process for forming tooth grooves and ensuring gear meshing accuracy. Its processing quality directly determines the overall transmission efficiency, operating noise, and service life of the geared motor.

[0003] Currently, existing worm gear hobbing equipment mainly adopts the end face hobbing method, which relies on gear fixtures to complete the workpiece clamping and positioning. The fixtures drive the workpiece to rotate in an indexing manner, and the rotating cutter head completes the tooth groove cutting and forming operation.

[0004] The following problems exist in the existing technology that have not been adequately solved: 1. After the gear hobbing is completed by the cutter head, a large number of machining burrs are easily generated at the edge of the tooth groove and the tooth ridge of the worm gear. At present, most of the industry adopts the operation mode of adding a separate grinding station and manually cleaning burrs after the gear hobbing is completed. This not only makes the process cumbersome, but also significantly lengthens the overall gear processing cycle and increases the cost of manpower and equipment. It is also easy to cause gear positioning deviation during secondary transfer and secondary clamping, which in turn causes a decrease in gear coaxiality and tooth profile accuracy. 2. The cutter head tools used in gear hobbing will gradually wear down during long-term continuous cutting operations. After the tool wears down, it will directly lead to insufficient depth of the machined tooth groove and deviation of tooth profile dimensions. However, the existing conventional gear hobbing equipment lacks the function of real-time detection of abnormal tooth groove processing dimensions, and cannot detect the tool wear in time. It can only rely on operators to stop the machine periodically to check the tool condition. This is not only inefficient, but also prone to batch defective products, resulting in waste of raw materials and production delays. Summary of the Invention

[0005] The purpose of this invention is to provide a gear hobbing device for components of a worm gear reducer motor, in order to solve the problems mentioned in the background art.

[0006] It also includes an arc-shaped support rotatably disposed in the middle of the gear fixture, and the top of the arc-shaped support is slidably connected to the inner top surface of the machine tool bracket. An arc-shaped grinding mechanism for cleaning burrs on the worm gear is movably installed inside the arc-shaped support.

[0007] The drive mechanism, which is mounted between the side wall of the cutter head and the arc-shaped support, is used to intermittently drive the arc-shaped grinding mechanism.

[0008] Preferably, the arc-shaped grinding mechanism includes: an arc-shaped groove formed inside the arc-shaped support, and a V-shaped cleaning plate is slidably arranged inside the arc-shaped groove. A detection rod is fixedly connected to the middle of the left side of the V-shaped cleaning plate, and the detection rod is movably inserted inside the arc-shaped support.

[0009] A return spring is movably installed on the inner wall of the arc-shaped groove to drive the detection rod to reset, and a limiting block is movably installed on the outer wall of the arc-shaped support to restrict the reset movement of the detection rod;

[0010] A guide groove is provided on the right side of the arc-shaped support. An adjusting block is slidably arranged inside the guide groove. The end of the V-shaped cleaning plate away from the outlet of the arc-shaped groove is slidably arranged inside the adjusting block. The end of the adjusting block extending out of the guide groove is movably connected to the drive mechanism.

[0011] Preferably, a spring telescopic rod is installed on the outer wall of the arc-shaped support, and the movable end of the spring telescopic rod is fixedly connected to the side wall of the limiting block;

[0012] The surface of the arc-shaped support is provided with a through groove that matches the arc-shaped groove. The detection rod is movably inserted inside the through groove, and a limit ring is fixedly sleeved on the surface of the detection rod. The bottom of the limit block is provided with an inclined surface that matches the limit ring for limiting.

[0013] Preferably, the top surface of the V-shaped cleaning plate near the adjusting block has a cleaning groove, the top of the arc-shaped support has a filter groove, a filter screen is fixedly connected inside the filter groove, and the coolant pipe inside the machine tool bracket extends to the top of the filter screen.

[0014] Preferably, the detection rod is installed in the middle of the side of the V-shaped cleaning plate away from the grinding surface, and the return spring is movably sleeved on the surface of the detection rod, and the return spring is disposed between the V-shaped cleaning plate and the inner wall of the arc groove.

[0015] Preferably, the driving mechanism includes: a moving groove formed in the lower part of the arc-shaped support, and an adjusting rod is slidably arranged inside the moving groove, the right end of the adjusting rod passing through the arc-shaped support and fixedly connected to a cone block;

[0016] A lever is rotatably mounted on the right side of the arc-shaped support to drive the adjustment block to move, and the lower part of the lever overlaps with the side wall of the cone block.

[0017] A protrusion fixedly installed on the outer circumference of the cutter head for intermittently pushing the adjusting rod.

[0018] Preferably, the upper part of the lever is provided with a waist-shaped groove, and the protruding end of the adjusting block is slidably disposed inside the waist-shaped groove;

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] In this invention, the linkage drive mechanism of the cutter head can simultaneously drive the arc-shaped grinding mechanism to automatically deburr the formed tooth grooves and edges during the hobbing and indexing operation of the worm gear. This eliminates the need for a separate cleaning station and manual finishing process, simplifies the processing flow, avoids positioning errors caused by secondary clamping of the workpiece, effectively shortens the processing cycle, and significantly improves the overall processing efficiency and forming accuracy of the worm gear.

[0023] In this invention, the tool wear status can be determined by the actual forming depth of the tooth groove through the linkage between the V-shaped cleaning plate and the detection rod. When the tool wear causes deviation in the tooth groove machining dimensions, the detection rod can lock the displacement. The staff can quickly identify the problem of excessive tool wear by visual observation, which facilitates timely repair and replacement of the tool, effectively avoids the generation of batches of products with unqualified dimensions, reduces production losses, and stabilizes product processing quality.

[0024] In this invention, the V-shaped cleaning plate arranged in an arc can be precisely adapted to the arc-shaped tooth groove structure of the worm gear, which can not only thoroughly remove the machining burrs, but also avoid excessive grinding and damage to the gear base. At the same time, with the coolant filtration and guiding structure, the metal chips generated by grinding can be discharged with the coolant in time, preventing the accumulation of chips from scratching the workpiece and wearing equipment parts, ensuring the long-term stable operation of the equipment, and reducing the frequency of equipment maintenance and operating costs.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 8 This invention provides a technical solution: a hobbing device for components of a worm gear reducer motor, comprising a machine tool support 1, a gear clamp 2 rotatably mounted on the right side of the inner wall of the machine tool support 1, and a cutter head 3 rotatably mounted on the left side of the inner wall of the machine tool support 1, which cooperates with the gear clamp 2. It should be noted that: the gear clamp 2 holds and fixes the worm gear; the cutter head 3 feeds to complete single-tooth hobbing; after cutting, the cutter head 3 retracts; subsequently, the gear clamp 2 drives the worm gear to rotate at its index, completing the shifting process before proceeding to the next tooth groove machining.

[0036] It also includes an arc-shaped support 4 rotatably disposed in the middle of the gear fixture 2, with the top of the arc-shaped support 4 slidably connected to the inner top surface of the machine tool support 1. An arc-shaped grinding mechanism 5 for cleaning burrs on the worm gear is movably installed inside the arc-shaped support 4. It should be noted that the arc-shaped support 4 is sleeved on the rotating shaft surface of the gear fixture 2 via a connecting bearing. A slider is fixedly connected to the top of the arc-shaped support 4. A groove is opened on the inner top surface of the machine tool support 1, and the upper part of the slider is slidably disposed inside the groove, so that the rotation of the gear fixture 2 will not interfere with the use of the arc-shaped support 4. Since burrs will be generated at the tooth edge position after the worm gear tooth groove is machined, these burrs need to be cleaned separately afterward, otherwise the use effect will be affected.

[0037] The drive mechanism 6, which is installed between the side wall of the cutter head 3 and the arc-shaped support 4, is used to intermittently drive the arc-shaped grinding mechanism 5.

[0038] In this embodiment, as Figures 1 to 8 As shown, the arc-shaped grinding mechanism 5 includes: an arc-shaped groove 501 opened inside the arc-shaped support 4, and a V-shaped cleaning plate 502 is slidably arranged inside the arc-shaped groove 501. A detection rod 503 is fixedly connected to the middle of the left side of the V-shaped cleaning plate 502, and the detection rod 503 is movably inserted inside the arc-shaped support 4.

[0039] A return spring 504 is movably installed on the inner wall of the arc-shaped groove 501 to drive the detection rod 503 to reset. A limiting block 505 is movably installed on the outer wall of the arc-shaped support 4 to restrict the reset movement of the detection rod 503. It should be noted that when the movement of the detection rod 503 exceeds the limited displacement, the limiting block 505 can prevent the moved detection rod 503 from resetting, thereby judging whether there is an abnormality in the tooth groove dimension machining by observing the position of the detection rod 503.

[0040] A guide groove 506 is formed on the right side of the arc-shaped support 4. An adjusting block 507 is slidably disposed inside the guide groove 506. The end of the V-shaped cleaning plate 502 away from the outlet of the arc-shaped groove 501 is slidably disposed inside the adjusting block 507. The end of the adjusting block 507 extending out of the guide groove 506 is movably connected to the drive mechanism 6. It should be noted that a recess is formed on the side of the adjusting block 507 near the end of the V-shaped cleaning plate 502. A sliding rod is disposed inside the recess. One end of the V-shaped cleaning plate 502 is slidably disposed on the surface of the sliding rod. This recess space is designed so that when the V-shaped cleaning plate 502 is grinding the tooth edges and burrs, and an unqualified tooth groove depth is detected, the V-shaped cleaning plate 502 will not cause interference as it moves inside the arc-shaped groove 501 with the detection rod 503.

[0041] In this embodiment, as Figures 1 to 8As shown, a spring telescopic rod 508 is installed on the outer wall of the arc-shaped support 4, and the movable end of the spring telescopic rod 508 is fixedly connected to the side wall of the limiting block 505. It should be noted that the spring telescopic rod 508 is used to drive the limiting block 505 to move back to its original position. When an abnormal position of the detection rod 503 is detected, the operator can release the limiting ring 510 by pulling the limiting block 505 to compress the spring telescopic rod 508.

[0042] The surface of the arc-shaped support 4 is provided with a through groove 509 that matches the arc-shaped groove 501. The detection rod 503 is movably inserted inside the through groove 509, and a limit ring 510 is fixedly sleeved on the surface of the detection rod 503. The bottom of the limit block 505 is set as an inclined surface that matches the limit ring 510 for limiting. It should be noted that: the through groove 509 is arc-shaped, and its length is the same as the trajectory length of the V-shaped cleaning plate 502 moving along the arc-shaped groove 501. The limiting block 505 is an arc-shaped block that mates with the through groove 509, and its length is 1.1 times the maximum radial travel of the V-shaped cleaning plate 502 within the arc-shaped groove 501. The grinding side of the V-shaped cleaning plate 502 has a chamfer that mates with the tooth groove, facilitating the insertion of the V-shaped cleaning plate 502 into the tooth groove. A safety clearance is provided between the V-shaped cleaning plate 502 and the inner wall of the tooth groove. When the machining tool is severely worn, the depth of the machined tooth groove decreases. At this time, when the V-shaped cleaning plate 502 enters the tooth groove position, it is limited by the tooth groove depth. The V-shaped cleaning plate 502 extends outward from the through groove 509 with the detection rod 503. When the detection rod 503 moves beyond the safety threshold with the limit rod, the limit ring 510 passes the limit block 505 and the limit block 505 restricts the detection rod 503 to reset. The arc groove 501 has a reserved lateral movement margin for the V-shaped cleaning plate 502. At the same time, the outer protrusion 605 of the cutter head 3 cooperates with the lever 604 to form a stroke limit, which limits the V-shaped cleaning plate 502 to slide only along the predetermined arc trajectory of the arc groove 501. When it is hindered by the tooth groove depth, the cleaning plate can only retract towards the side where the through groove 509 is located. The movement trajectory is unique and without deviation, ensuring that the tool wear detection action is stable and reliable.

[0043] In this embodiment, as Figures 1 to 8 As shown, a cleaning groove 511 is formed on the top surface of the V-shaped cleaning plate 502 near the adjusting block 507, and a filter groove is formed on the top of the arc-shaped support 4. A filter screen 512 is fixedly connected inside the filter groove, and the coolant pipe inside the machine tool bracket 1 extends to the top of the filter screen 512. It should be noted that: after being filtered by the filter screen 512, the coolant enters the cleaning groove 511 of the V-shaped cleaning plate 502. After the filtered liquid flows out from the arc-shaped groove 501 and the inside of the V-shaped cleaning plate 502, it carries away the grinding powder at the same time, achieving a self-cleaning effect.

[0044] In this embodiment, as Figures 1 to 8As shown, the detection rod 503 is installed in the middle of the V-shaped cleaning plate 502 on the side away from the grinding surface. The return spring 504 is movably sleeved on the surface of the detection rod 503, and the return spring 504 is located between the V-shaped cleaning plate 502 and the inner wall of the arc groove 501. It should be noted that multiple short springs that cooperate with the return spring 504 can be provided on the surface of the V-shaped cleaning plate 502 to assist the V-shaped cleaning plate 502 in resetting and moving.

[0045] In this embodiment, as Figures 1 to 8 As shown, the drive mechanism 6 includes: a moving groove 601 opened at the lower part of the arc-shaped support 4, and an adjusting rod 602 is slidably arranged inside the moving groove 601. The right end of the adjusting rod 602 passes through the arc-shaped support 4 and is fixedly connected to a cone block 603.

[0046] The lever 604, which is rotatably mounted on the right side of the arc-shaped support 4 to drive the adjustment block 507 to move, has its lower part overlapping the side wall of the cone block 603.

[0047] A protrusion 605 is fixedly installed on the outer circumference of the cutter head 3 for intermittently pushing the adjusting rod 602. It should be noted that when the cutter head 3 moves towards the gear clamp 2, the rotation trajectory of the protrusion 605 covers the end position of the adjusting rod 602. When the cutter head 3 retracts, the rotation of the protrusion 605 cannot contact the adjusting rod 602.

[0048] In this embodiment, as Figures 1 to 8 As shown, the upper part of the lever 604 has a waist-shaped groove 606, and the protruding end of the adjusting block 507 is slidably disposed inside the waist-shaped groove 606. It should be noted that when the lever 604 swings, it drives the adjusting block 507 to slide along the trajectory of the guide groove 506 through the waist-shaped groove 606, so that the adjusting block 507, carrying the V-shaped cleaning plate 502, extends out from inside the arc-shaped groove 501 to perform burr cleaning, and the rotation cycle of the gear clamp 2 with the worm gear can cover the burr cleaning operation of all tooth grooves.

[0049] A groove is provided on the right side of the arc-shaped support 4. The fulcrum end of the lever 604 is rotatably mounted inside the groove via a bearing, and a torsion spring is fixedly connected between the inner wall of the groove and the fulcrum end of the lever 604. It should be noted that the lever 604 is driven to move back to its original position by the torsion spring, and a return spring is installed inside the arc-shaped groove 501 to drive the adjusting block 507 to move back to its original position. The auxiliary lever 604 carries the adjusting block 507 to move back to its original position along the trajectory of the arc-shaped groove 501. The use and effect of this return spring are common technical means and will not be described in detail.

[0050] In this embodiment, as Figures 1 to 8As shown, the end of the adjusting rod 602 facing the protrusion 605 is set as a ball head, and a return spring 607 for driving the adjusting rod 602 to reset is fixedly connected inside the moving groove 601. It should be noted that: the ball head of the adjusting rod 602 cooperates with the inclined surface of the protrusion 605, so that the protrusion 605 can squeeze the adjusting rod 602 to slide inside the moving groove 601. After the protrusion 605 and the adjusting rod 602 come into contact and fit together, the return spring 607 drives the adjusting rod 602 to reset. Therefore, during the rotation of the cutter head 3, the adjusting rod 602 can be moved intermittently by the protrusion 605. The movement of the adjusting rod 602 drives the V-shaped cleaning plate 502 to move back and forth in the corresponding tooth groove through the drive mechanism 6 to clean burrs.

[0051] The method of use and advantages of this invention: The gear hobbing device for the worm gear reducer motor components operates as follows:

[0052] like Figures 1 to 8 As shown, during the operation, the worm gear is first fixed on the gear fixture 2, and the worm gear tooth groove cutting operation is completed with the help of the tool equipped on the cutter head 3. After a single set of tooth grooves is formed, the cutter head 3 performs a retraction and reset action, and the gear fixture 2 simultaneously carries the worm gear to complete the indexing rotation positioning, and switches to the next station to carry out subsequent tooth groove cutting.

[0053] When the cut tooth groove is transferred back to the corresponding area of ​​the arc support 4 along with the worm gear, the cutter head 3 in operation, with the protrusion 605 on its surface, intermittently pushes and squeezes the end of the adjusting rod 602 at the bottom of the arc support 4. The adjusting rod 602 is driven by the inclined guiding force of the protrusion 605, and the cone 603 moves axially toward the lever 604, causing the lower end face of the lever 604 to be in contact with the cone surface of the cone 603 and be subjected to force, so that the lever 604 completes the deflection swing with the preset fulcrum on the arc support 4 as the rotation center.

[0054] The upper end of the lever 604 is driven by the waist-shaped groove 606 to drive the adjusting block 507 to slide along the path defined by the guide groove 506. Then, the adjusting block 507 drives the movable V-shaped cleaning plate 502 to extend outward from the inside of the arc groove 501. The V-shaped cleaning plate 502 is precisely fitted into the gap between the two adjacent sets of tooth grooves of the worm gear along the arc movement trajectory, and performs fine grinding and chip removal on the outer edge of the tooth edge. This realizes the synchronous and coordinated operation of tooth groove grooving and burr cleaning, eliminating the need for subsequent separate cleaning processes, and effectively improving the gear processing and forming accuracy and overall processing efficiency.

[0055] When the cutter head 3 experiences wear and tear, the cutting depth of the worm gear forming groove will show dimensional deviation and reduction. Subsequently, when the V-shaped cleaning plate 502 enters the abnormally sized groove for cleaning, it is constrained and squeezed by the inner wall of the groove, causing the V-shaped cleaning plate 502 to retract and move in the direction of the inner through groove 509 of the arc-shaped support 4, simultaneously driving the detection rod 503 to extend and move outward of the through groove 509;

[0056] As the detection rod 503 moves with displacement, its outer limiting ring 510 passes over the guide slope of the limiting block 505. After resetting, the limiting block 505 can axially limit and lock the detection rod 503 after displacement. By observing the offset change of the exposed position of the detection rod 503, the operator can accurately determine that the tool wear has reached the service limit and carry out tool replacement and maintenance operations in a timely manner.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
