Description

Technical Field

[0001] This invention relates to the field of gear machining technology, specifically to a fixture device for gear shaping cutter machining that is easy to assemble and disassemble. Background Technology

[0002] Gear shaper cutters are commonly used tools in gear machining, mainly used to machine complex tooth profile parts such as spur gears, helical gears, and internal gears. Their machining accuracy directly affects the meshing performance and service life of gears. Currently, the traditional fixtures used in gear shaper cutting mostly adopt structures such as bolt fastening or flange connection. Although they can meet the requirements of clamping stability to a certain extent, they have defects in actual operation.

[0003] Traditional gear shaper fixtures are extremely cumbersome to install and disassemble. The common method involves fastening with bolts and nuts, requiring a significant amount of time to tighten the bolts and adjust the position each time the gear shaper is replaced. This severely reduces production efficiency. In some large-scale gear machining production lines with extremely high efficiency requirements, frequent gear shaper replacements can lead to prolonged production line downtime and increased production costs due to the cumbersome disassembly and assembly process. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fixture device for easy assembly and disassembly of a gear shaping cutter, comprising:

[0005] The mounting plate and the mounting holes at the four corners of the mounting plate surface are used to fix the mounting plate to the external processing equipment through the mounting holes on the surface to realize the overall installation and positioning of the device. A fixing mechanism is fixedly installed at the bottom of the mounting plate, which is used to fix the clamp of the tool.

[0006] The mounting mechanism is detachably mounted on the bottom of the fixing mechanism and is used to mount the cutting tool.

[0007] Gear shaping tool, which can be detachably installed inside the mounting mechanism;

[0008] The mounting mechanism includes a fixing sleeve, with a retaining ring fixedly installed at the bottom of the inner wall of the fixing sleeve for positioning the gear shaping cutter. The inner wall of the fixing sleeve has a strip-shaped groove and a wedge-shaped groove, and mounting grooves are provided on both sides of the fixing sleeve. An mounting component is installed inside the mounting groove and slides inside the strip-shaped groove. The mounting component cooperates with the fixing mechanism to fix the mounting mechanism. A tool fixing component is installed inside the wedge-shaped groove and is used to fix the gear shaping cutter. The tool fixing component and the mounting component are pressed and adapted to each other, and the two cooperate to strengthen the fixation of the gear shaping cutter by the tool fixing component.

[0009] Preferably, there are two strip grooves and two wedge grooves, which are spaced apart on the inner wall of the fixed sleeve.

[0010] Preferably, the fixing mechanism includes a fixing seat, which is fixedly installed at the middle of the bottom of the mounting plate. A support column is fixedly installed at the bottom of the fixing seat, and a conical block is fixedly installed at the bottom of the support column. Triangular grooves are formed on both sides of the outer surface of the conical block.

[0011] Preferably, the gear shaping tool includes a gear shaping tool body, an mounting rod is fixedly installed at the axis of the gear shaping tool body, and a cylindrical retaining block is fixedly installed at the axis of the other end of the mounting rod. The outer surface of the cylindrical retaining block is provided with an annular groove. The end of the mounting rod near the cylindrical retaining block is squeezed and adapted to the retaining ring. The retaining ring plays a positioning role when the gear shaping tool is inserted, thereby improving the installation efficiency.

[0012] Preferably, the mounting component includes a sliding plate and a fixing component. Slider blocks are fixedly mounted on both sides of the sliding plate. The slider blocks are slidably mounted inside the strip groove. A buffer spring is fixedly connected between the bottom of the slider block and the inner wall of the strip groove. Reinforcing members are mounted on both sides of the top of the sliding plate. The reinforcing members are slidably mounted on both sides of the fixing component. The fixing component is installed inside the mounting groove.

[0013] Preferably, a rubber pad is fixedly installed at the axis of the bottom of the slide plate. The rubber pad is pressed and matched with the top of the cylindrical clamping block. When installing the gear cutting tool, the cylindrical clamping block is aligned with the retaining ring and inserted. The cylindrical clamping block presses the rubber pad to make the slide plate move upward. When the buffer spring is stretched, the slide plate presses the tool fixing component to clamp the gear cutting tool.

[0014] Preferably, there are two fasteners, and the two fasteners are respectively installed in the mounting slots on both sides of the fixing sleeve. Each fastener includes a mounting base, which is fixedly installed on both sides of the inner wall of the mounting slot. A rotating shaft is rotatably mounted between the mounting bases via a bracket. An L-shaped locking rod is fixedly installed on the outer surface of the rotating shaft. The bent part of the L-shaped locking rod is engaged with the triangular groove. A guide bead is fixedly installed on the top of the outer curved surface of the L-shaped locking rod. The guide bead is pressed and engaged with the conical block. Reinforcing grooves are provided on both sides of the L-shaped locking rod. When installing the mounting mechanism, the fixing sleeve shaft is aligned with the conical block and inserted. The conical block presses the guide bead to rotate the L-shaped locking rod until the bent part of the L-shaped locking rod is engaged with the triangular groove to complete the initial fixation.

[0015] Preferably, the reinforcing component includes a connecting rod and a telescopic arc rod. The connecting rod is fixedly installed on both sides of the top of the slide plate and positioned directly above the slider. A connecting seat is rotatably installed on the top of the connecting rod via a pivot. Reinforcing blocks are rotatably installed at both ends of the telescopic arc rod via pivots. The reinforcing blocks are slidably installed inside the reinforcing groove. A buffer spring is fixedly connected between the reinforcing block and the inner wall of the reinforcing groove. The connecting seat is fixedly installed in the middle of the telescopic arc rod. When installing the gear cutter, the slide plate moves upward, driving the connecting rod to push the telescopic arc rod upward. The reinforcing block moves within the reinforcing groove, and the buffer spring stretches. Due to the inclined setting of the reinforcing groove, when the reinforcing block moves upward within the reinforcing groove, the reinforcing block exerts a central pulling force on the L-shaped locking rod, strengthening the locking effect between the L-shaped locking rod and the triangular groove and preventing loosening.

[0016] Preferably, the tool fixing component includes a rotating base, which is rotatably mounted inside the wedge-shaped groove via a rotating shaft. An L-shaped rotating plate is fixedly mounted on the surface of the rotating base. There are two L-shaped rotating plates, and the two L-shaped rotating plates are arranged in the wedge-shaped grooves on both sides of the fixing sleeve. A return spring is fixedly connected between the top ends of the L-shaped rotating plates.

[0017] Preferably, an arc-shaped locking block is slidably installed at the end of the L-shaped rotating plate away from the return spring. The arc-shaped locking block is engaged and adapted with the annular groove. A fixing spring is installed inside the arc-shaped locking block. The other end of the fixing spring is fixedly installed at the end of the L-shaped rotating plate. When the gear cutter is inserted, the sliding plate presses against the L-shaped rotating plate, the cylindrical locking block presses against the arc-shaped locking block, the return spring is compressed, and when the annular groove moves to the arc-shaped locking block, the two engage. At this time, the sliding plate abuts against the L-shaped rotating plate to improve the fixing effect.

[0018] This invention provides a fixture device for machining gear shapers that is easy to assemble and disassemble. It has the following advantages:

[0019] 1. This gear hobbing cutter machining fixture is easy to assemble and disassemble. Through the setting of a fixing mechanism and an installation mechanism, during installation, the fixing sleeve is aligned with the conical block and inserted. The conical block presses the guide bead, causing the L-shaped locking rod to rotate around the rotating shaft until its bend is engaged with the triangular groove to complete the initial fixation. During disassembly, the L-shaped locking rod is moved to disengage it from the triangular groove, and the fixing sleeve can be removed. The conical block of the fixing mechanism and the L-shaped locking rod of the installation mechanism cooperate to complete the assembly and disassembly of the installation mechanism without tools, shortening the time for changing different specifications of installation mechanisms, improving the equipment's flexibility in adapting to different cutting tools, and making it suitable for machining various types of gear hobbing cutters.

[0020] Second, the gear shaping cutter uses a convenient assembly and disassembly fixture device. Through the setting of the retaining ring and the mounting rod, when installing the gear shaping cutter, the end of the mounting rod near the cylindrical retaining block is aligned with the retaining ring and inserted. The two are pressed into contact, quickly determining the axial position of the gear shaping cutter body. The retaining ring plays a positioning role for the mounting rod, reducing the alignment operation during installation, reducing the difficulty of manual operation, and enabling the gear shaping cutter to be installed quickly and efficiently.

[0021] Third, the gear shaping cutter uses a convenient assembly and disassembly fixture device. Through the cooperation of the tool fixing part and the mounting part, when the gear shaping cutter is inserted, the cylindrical locking block pushes the slide plate upward. The slide plate squeezes the L-shaped rotating plate to make it rotate around the rotating base. When the annular groove moves to the arc-shaped locking block, the arc-shaped locking block is locked into the annular groove under the action of the fixed spring. At the same time, the slide plate continues to press against the L-shaped rotating plate. With the rebound force of the return spring, the fixation is strengthened, so that the arc-shaped locking block is tightly locked with the annular groove. This prevents the gear shaping cutter from loosening or shifting due to vibration during the processing, ensuring processing accuracy and reducing the scrap rate.

[0022] IV. The gear hobbing cutter uses a convenient assembly and disassembly fixture device. Through the cooperation of the reinforcing parts and the fixing parts, the slide plate moves upward, driving the connecting rod to push the telescopic arc rod upward. The reinforcing block slides along the inclined reinforcing groove, and the buffer spring is stretched. The reinforcing block generates a central pulling force on the L-shaped clamping rod, making the L-shaped clamping rod more tightly locked into the triangular groove. The pulling force of the reinforcing parts further strengthens the connection between the mounting mechanism and the fixing mechanism, avoiding the loosening of the mounting mechanism due to high-frequency vibration during processing, improving the structural stability of the overall device, and extending the service life of the equipment.

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.

[0038] First embodiment, such as Figures 1 to 8 As shown, the present invention provides a technical solution: a fixture device for easy assembly and disassembly of gear hobbing cutter machining, comprising:

[0039] Mounting plate 1, and mounting holes 5 at the four corners of the surface of mounting plate 1.

A fixing mechanism 2 is fixedly installed at the bottom of mounting plate 1. The fixing mechanism 2 is used to fix the tool clamp.

[0040] The fixing mechanism 2 includes a fixing seat 21, which is fixedly installed in the middle of the bottom of the mounting plate 1. A support column 22 is fixedly installed at the bottom of the fixing seat 21, and a conical block 23 is fixedly installed at the bottom of the support column 22. Triangular grooves 24 are provided on both sides of the outer surface of the conical block 23.

[0041] Mounting mechanism 4 is detachably mounted on the bottom of fixing mechanism 2 and is used to mount the cutting tool.

[0042] The mounting mechanism 4 includes a fixing sleeve 41. A retaining ring 42 is fixedly installed on the bottom of the inner wall of the fixing sleeve 41. The retaining ring 42 is used to position the gear cutting tool 3. The inner wall of the fixing sleeve 41 is provided with a strip groove 43 and a wedge groove 46. The two sides of the fixing sleeve 41 are provided with mounting grooves 44. An mounting part 45 is installed inside the mounting groove 44. The mounting part 45 is slidably installed inside the strip groove 43. The mounting part 45 cooperates with the fixing mechanism 2 to fix the mounting mechanism 4. A tool fixing part 47 is installed inside the wedge groove 46. The tool fixing part 47 is used to fix the gear cutting tool 3. The tool fixing part 47 and the mounting part 45 are squeezed and adapted to each other. The two cooperate to strengthen the fixation of the tool fixing part 47 on the gear cutting tool 3.

[0043] There are two strip grooves 43 and two wedge grooves 46, which are spaced apart on the inner wall of the fixed sleeve 41.

[0044] Gear shaping cutter 3 is detachably installed inside the mounting mechanism 4;

[0045] The gear shaping cutter 3 includes a gear shaping cutter body 31. An installation rod 32 is fixedly installed at the axis of the gear shaping cutter body 31. A cylindrical retaining block 33 is fixedly installed at the axis of the other end of the installation rod 32. An annular groove 34 is formed on the outer surface of the cylindrical retaining block 33. The end of the installation rod 32 near the cylindrical retaining block 33 is pressed and matched with a retaining ring 42. The retaining ring 42 plays a positioning role when the gear shaping cutter 3 is inserted, thereby improving the installation efficiency.

[0046] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 9 to 13 As shown, the mounting component 45 includes a slide plate 451 and a fixing component 455. Sliders 452 are fixedly mounted on both sides of the slide plate 451. The sliders 452 are slidably mounted inside the strip groove 43. A buffer spring 454 is fixedly connected between the bottom of the sliders 452 and the inner wall of the strip groove 43. Reinforcing members 456 are mounted on both sides of the top of the slide plate 451. The reinforcing members 456 are slidably mounted on both sides of the fixing component 455. The fixing component 455 is installed inside the mounting groove 44.

[0047] A rubber pad 453 is fixedly installed at the shaft center of the bottom of the slide plate 451. The rubber pad 453 is pressed and matched with the top of the cylindrical clamping block 33. When installing the gear shaping cutter 3, the cylindrical clamping block 33 is aligned with the retaining ring 42 and inserted. The cylindrical clamping block 33 presses the rubber pad 453 to make the slide plate 451 move upward. The buffer spring 454 is stretched. At this time, the slide plate 451 presses the tool fixing member 47 to clamp the gear shaping cutter 3.

[0048] The tool holder 47 includes a rotating base 471, which is rotatably mounted inside the wedge groove 46 via a rotating shaft. An L-shaped rotating plate 472 is fixedly mounted on the surface of the rotating base 471. There are two L-shaped rotating plates 472, and the two L-shaped rotating plates 472 are arranged in the wedge grooves 46 on both sides of the fixed sleeve 41. A return spring 474 is fixedly connected between the top ends of the L-shaped rotating plates 472.

[0049] An arc-shaped locking block 473 is slidably installed at one end of the L-shaped rotating plate 472 away from the return spring 474. The arc-shaped locking block 473 is engaged with the annular groove 34. A fixing spring 475 is installed inside the arc-shaped locking block 473. The other end of the fixing spring 475 is fixedly installed at the end of the L-shaped rotating plate 472. When the gear cutter 3 is inserted, the slide plate 451 presses against the L-shaped rotating plate 472, the cylindrical locking block 33 presses against the arc-shaped locking block 473, the return spring 474 is compressed, and when the annular groove 34 moves to the arc-shaped locking block 473, the two engage. At this time, the slide plate 451 abuts against the L-shaped rotating plate 472 to improve the fixing effect.

[0050] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 11 As shown, there are two fasteners 455, and the two fasteners 455 are respectively installed in the mounting grooves 44 on both sides of the fixing sleeve 41. The fastener 455 includes a mounting base 4551, which is fixedly installed on both sides of the inner wall of the mounting groove 44. A rotating shaft 4552 is rotatably mounted between the mounting bases 4551 via a bracket. An L-shaped locking rod 4553 is fixedly mounted on the outer surface of the rotating shaft 4552. The bent part of the L-shaped locking rod 4553 is connected to the triangular groove 24. The L-shaped locking rod 4553 has a guide bead 4554 fixedly installed on the top of its outer curved surface. The guide bead 4554 is pressed and matched with the conical block 23. The L-shaped locking rod 4553 has a reinforcing groove 4555 on both sides. When installing the mounting mechanism 4, the fixing sleeve 41 is aligned with the axis of the conical block 23 and inserted. The conical block 23 presses the guide bead 4554 to make the L-shaped locking rod 4553 rotate until the bent part of the L-shaped locking rod 4553 is engaged in the triangular groove 24 to complete the initial fixation.

[0051] The reinforcement component 456 includes a connecting rod 4561 and a telescopic arc-shaped rod 4563. The connecting rod 4561 is fixedly installed on both sides of the top of the slide plate 451. The connecting rod 4561 is positioned directly above the slider 452. A connecting seat 4562 is rotatably mounted on the top of the connecting rod 4561 via a pivot. Reinforcing blocks 4564 are rotatably mounted on both ends of the telescopic arc-shaped rod 4563 via pivots. The reinforcing blocks 4564 are slidably installed inside the reinforcing groove 4555. A buffer spring 4565 is fixedly connected between the reinforcing blocks 4564 and the inner wall of the reinforcing groove 4555. The connector 4562 is fixedly installed in the middle of the telescopic arc rod 4563. When the gear cutter 3 is installed, the slide plate 451 moves upward, driving the connecting rod 4561 to push the telescopic arc rod 4563 upward. The reinforcing block 4564 moves in the reinforcing groove 4555, and the buffer spring 4565 is stretched. Since the reinforcing groove 4555 is inclined, when the reinforcing block 4564 moves upward in the reinforcing groove 4555, the reinforcing block 4564 has a central pulling force on the L-shaped locking rod 4553, which strengthens the locking effect between the L-shaped locking rod 4553 and the triangular groove 24 and prevents loosening.

[0052] In use, the mounting plate 1 is fixed to the designated position of the external processing equipment through the mounting holes 5 at the four corners of the surface using bolts, thus completing the basic positioning of the entire fixture device. The fixing sleeve 41 of the mounting mechanism 4 is aligned with the conical block 23 of the fixing mechanism 2 and inserted. During the insertion process, the outer surface of the conical block 23 presses the guide bead 4554 of the fixing member 455, causing the L-shaped locking rod 4553 to rotate outward around the rotating shaft 4552. When the fixing sleeve 41 moves to the designated position, the bent part of the L-shaped locking rod 4553 is aligned with the triangular groove 24 of the conical block 23 and is inserted into the triangular groove 24, thus completing the initial fixing of the mounting mechanism 4 and the fixing mechanism 2.

[0053] Align the mounting rod 32 of the gear shaping cutter 3 with the retaining ring 42 at the bottom of the fixed sleeve 41 and insert it vertically upwards. The end of the mounting rod 32 near the cylindrical retaining block 33 presses against the retaining ring 42, and the retaining ring 42 quickly positions the gear shaping cutter body 31 to ensure that the axis is aligned with the center of the device. When inserting further, the top of the cylindrical retaining block 33 presses against the rubber pad 453 at the bottom of the slide plate 451, pushing the slide plate 451 to move upwards. The slider 452 slides along the strip groove 43, stretching the buffer spring 454. During the upward movement of the slide plate 451, it presses against the L-shaped rotating plate 472 of the fixed cutter 47, causing the clamping end of the L-shaped rotating plate 472 to rotate inwards around the rotating seat 471, while compressing the return spring 474 at the top of the L-shaped rotating plate 472.

[0054] When the annular groove 34 of the cylindrical locking block 33 moves to align with the arc-shaped locking block 473 at the end of the L-shaped rotating plate 472, the arc-shaped locking block 473 springs into the annular groove 34 under the elastic force of the fixing spring 475, thereby achieving radial fixation of the gear cutting tool 3. At this time, the slide plate 451 continues to press against the L-shaped rotating plate 472, and with the return force of the reset spring 474, the locking strength between the arc-shaped locking block 473 and the annular groove 34 is strengthened.

[0055] When the slide plate 451 moves upward, it drives the connecting rods 4561 on both sides to push the telescopic arc rod 4563 upward, so that the reinforcing blocks 4564 at both ends of the telescopic arc rod 4563 slide upward along the reinforcing groove 4555 of the L-shaped clamp rod 4553, stretching the buffer spring 4565. Since the reinforcing groove 4555 is inclined, the reinforcing block 4564 generates a pulling force towards the center on the L-shaped clamp rod 4553 when it moves upward, so that the bend of the L-shaped clamp rod 4553 is more tightly inserted into the triangular groove 24, preventing the installation mechanism 4 from loosening.

[0056] When the gear shaping cutter 3 needs to be disassembled, pull down the gear shaping cutter body 31, and the cylindrical locking block 33 moves down accordingly. The buffer spring 454 rebounds, driving the slide plate 451 to reset downward, releasing the pressure on the L-shaped rotating plate 472. The reset spring 474 rebounds, pushing the L-shaped rotating plate 472 to rotate around the rotating seat 471. The arc-shaped locking block 473 compresses the fixing spring 475 under the pressure of the annular groove 34, disengaging from the annular groove 34 and releasing the fixation on the gear shaping cutter 3. At the same time, the slide plate 451 moves down, driving the connecting rod 4561 and the telescopic arc rod 4563 to reset. The reinforcing block 4564 moves down along the reinforcing groove 4555 under the rebound of the buffer spring 4565, releasing the centering pull on the L-shaped locking rod 4553, removing the gear shaping cutter 3. Continue to pull down the gear shaping cutter body 31, causing the mounting rod 32 to disengage from the retaining ring 42, completing the disassembly of the gear shaping cutter 3.

[0057] When the mounting mechanism 4 needs to be disassembled, pull the end of the L-shaped lever 4553 outward to disengage its bent part from the triangular groove 24, and pull the fixing sleeve 41 vertically downward to separate the fixing sleeve 41 from the conical block 23, thus completing the disassembly of the mounting mechanism 4.

[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
