Description

Technical Field

[0001] The present invention relates to the technical field of gear processing, and in particular to an automatic unloading fixture for a gear shaping machine. Background Art

[0002] A gear shaper is a metal-cutting machine primarily used for machining internal and external spur and helical cylindrical gears, as well as other gear-shaped components. Currently, when machining an internal ring gear, the gear cutter is placed in a fixture and secured. The gear shaper then generates the gear teeth by performing a vertical reciprocating linear motion and a rotating motion, synchronized with the rotation of the internal ring gear.

[0003] However, most existing gear shaping machine fixtures have simple structures. When fixing the internal gear ring blank, the positions of multiple sets of clamping blocks need to be adjusted individually and multiple times to center the internal gear ring blank. The fixing operation is cumbersome and laborious. At the same time, due to the cutting motion of the gear shaping cutter and the internal gear ring blank, the internal gear ring blank reaches a high temperature after reprocessing, making it inconvenient for the processing personnel to unload the blank. This not only easily causes burns to the processing personnel, but also reduces the processing efficiency of the internal gear ring. Therefore, to address the above technical problems, an automatic unloading fixture for a gear shaping machine is proposed. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention proposes an automatic unloading fixture for a gear shaping machine, which is convenient and labor-saving for fixing the internal gear ring blank, and facilitates the unloading of the internal gear ring after processing, thereby improving the safety of the unloading process and improving the processing efficiency of the internal gear ring.

[0005] An automatic unloading fixture for a gear shaping machine, comprising:

[0006] A base capable of being mounted on a gear shaping machine, the base including a first end and a second end opposite to each other along a length direction;

[0007] The clamping mechanism includes a mounting ring, a rotating ring, a guide rod, a first drive assembly, and a second drive assembly, wherein the mounting ring is arranged on the top surface of the first end portion, the rotating ring is coaxially and rotatably arranged on the top of the mounting ring, the first drive assembly is arranged on the mounting ring, and is used to drive the rotating ring to rotate, three groups of guide rods are evenly arranged on the inner side of the rotating ring along its circumference, and the three groups of guide rods can all slide radially along the rotating ring, and clamping rods are arranged opposite to the three groups of guide rods, and the second drive assembly is arranged on the rotating ring, and is used to drive the three groups of clamping rods to close or open; and

[0008] The unloading mechanism includes a carrying plate, a lifting assembly and a moving assembly. A unloading hole is vertically opened on the top surface of the second end. The carrying plate is installed in the unloading hole through the lifting assembly so that the carrying plate can move in the vertical direction. The mounting ring is installed on the base through the moving assembly so that the mounting ring can move back and forth between the first end and the top of the carrying plate.

[0009] The beneficial effects of the automatic unloading fixture for a gear shaping machine are as follows:

[0010] 1. Place the inner gear ring blank on the base and between the three sets of clamping rods, and then use the second drive assembly to drive the three sets of clamping rods to close and move. The three sets of clamping rods close and move to contact the outer circumference of the inner gear ring blank and push the inner gear ring blank to move. When the three sets of clamping rods all contact the outer circumference of the inner gear ring blank, the inner gear ring blank can be centered and clamped, which makes fixing the inner gear ring blank convenient and labor-saving.

[0011] 2. When the inner gear ring blank is processed, the moving assembly is started to drive the mounting ring to move the processed inner gear ring through the rotating ring. When the mounting ring moves to the top of the carrying plate, the inner gear ring is located at the top of the carrying plate. At this time, the three sets of clamping rods are driven to open and move by the second driving assembly. The three sets of clamping rods are opened and moved to cancel the fixation of the inner gear ring. Then, the carrying plate is driven downward by controlling the lifting assembly. The downward movement of the carrying plate can drive the inner gear ring to move downward. When the inner gear ring moves downward and moves out of the mounting ring, the mounting ring can be moved in the opposite direction to the first end by starting the moving assembly. At this time, the inner gear ring remains on the carrying plate for cooling. At the same time, the inner gear ring blank can be placed between the three sets of clamping rods again for clamping processing, which is convenient for unloading of the inner gear ring after processing, improves the safety of the unloading process and improves the processing efficiency of the inner gear ring.

The divergent ends of the three groups of first screws extend outside the rotating ring and are coaxially provided with the bevel gears, and the bevel gear ring is coaxially rotatably sleeved on the circumferential side of the rotating ring, and the bevel gear ring is meshed with the three groups of bevel gears. By rotating the bevel gear ring and engaging with the three sets of bevel gears, the three sets of first screws can be driven to rotate. The rotation of the three sets of first screws and the three sets of guide rod threads can drive the three sets of clamping rods to close and move. By rotating the bevel gear ring in the opposite direction and engaging with the three sets of bevel gears, the three sets of first screws can be driven to rotate in the opposite direction. The reverse rotation of the three sets of first screws and the three sets of guide rod threads can drive the three sets of clamping rods to open and move. It is convenient to drive the three sets of clamping rods to close or open, and the three sets of clamping rods can be fixed by stopping the rotation of the bevel gear ring, which makes it convenient to fix the three sets of clamping rods.

[0014] In one embodiment, the second drive assembly further includes a worm and an incomplete worm gear ring; the worm is rotatably arranged on the circumferential side of the rotating ring, the incomplete worm gear ring is arranged on the circumferential side of the bevel gear ring and is coaxial with the bevel gear ring, and the worm is meshed with the incomplete worm gear ring. The bevel gear ring can be driven to rotate by rotating the worm and meshing with the incomplete worm gear ring, and the bevel gear ring can be driven to rotate in the opposite direction by rotating the worm and meshing with the incomplete worm gear ring in the opposite direction. Driving the bevel gear ring to rotate is convenient and labor-saving, and the bevel gear ring can be fixed by stopping the rotation of the worm, which is convenient for fixing the bevel gear ring. The self-locking structure formed by the meshing of the worm and the incomplete worm gear ring and the self-locking structure formed by the threaded cooperation of the first screw and the guide rod can improve the stability of the three sets of clamping rods in clamping the inner gear ring blank, avoid the inner gear ring blank from loosening due to machining vibration, accidental touch, etc. during machining, and ensure the accuracy of the inner gear ring machining.

[0059] When processing the inner gear ring, the inner gear ring blank is placed on the base 10 and located between the three sets of clamping rods 2021. Then, the bevel gear ring 403 is driven to rotate by rotating the worm 404 and engaging with the incomplete worm gear ring 405. The bevel gear ring 403 is engaged with the three sets of bevel gears 401 to drive the three sets of first screws 402 to rotate. The three sets of first screws 402 rotate and cooperate with the three sets of guide rods 202 to drive the three sets of clamping rods 2021 to close and move. The three sets of clamping rods 2021 are closed. The movement of the three sets of clamping rods 2021 can contact the outer peripheral surface of the inner ring blank and push the inner ring blank to move. When the three sets of clamping rods 2021 all contact the outer peripheral surface of the inner ring blank, stop rotating the worm 404 to center and clamp the inner ring blank. Fixing the inner ring blank is convenient and labor-saving, and the double self-locking structure can improve the stability of the three sets of clamping rods 2021 in clamping the inner ring blank, avoiding the loosening of the inner ring blank due to machining vibration, accidental touch, etc. during machining, thereby ensuring the accuracy of the inner ring machining.

[0060] Then, the gear shaping machine is started to control the gear shaping cutter to perform reciprocating linear motion and rotational motion in the vertical direction and the first motor 301 is started to drive the rotating ring 201 to rotate the inner gear ring blank through the engagement of the gear 302 with the outer gear ring 303, so as to form a generating motion to process the inner gear ring blank.

[0061] When the inner gear ring is processed, the second motor 503 is started to drive the second screw 502 to rotate. The rotation of the second screw 502 and the threaded engagement of the connecting seat 504 can drive the mounting ring 20 to move, so that the mounting ring 20 drives the inner gear ring from the top of the first end 101 through the multiple sets of chip removal grooves 105 to the top of the carrier plate 50. At this time, the cuttings in the mounting ring 20 can be discharged from the mounting ring 20 through the multiple sets of chip removal grooves 105 and fall into the collection box 106, which makes it convenient and labor-saving to remove the chips and facilitates the subsequent centralized processing of the chips. When the inner gear ring moves to the top of the carrier plate 50, the bevel gear ring 403 can be rotated in the opposite direction by rotating the worm 404 in the opposite direction, so that the three sets of clamping rods 2021 are opened and moved to cancel the clamping and fixation of the inner gear ring, and then the hydraulic expansion and contraction are controlled. The column 501 contracts to drive the carrier plate 50 to move the inner gear ring downward. When the inner gear ring moves downward and moves out of the mounting ring 20 and the carrier plate 50 is located below the receiving ring groove 1031, the second motor 503 is started to drive the second screw 502 to rotate in the opposite direction to move the mounting ring 20 in the opposite direction to the first end 101. At this time, the inner gear ring remains on the carrier plate 50 for cooling. At the same time, the inner gear ring blank can be placed between the three groups of clamping rods 2021 again for clamping processing, which is convenient for unloading the inner gear ring after processing, improving the safety of the unloading process and improving the processing efficiency of the inner gear ring. At the same time, by starting the blower 701, the inner gear ring can be blown through multiple groups of air outlets 703. By blowing air to the inner gear ring, the cooling time of the inner gear ring can be reduced.
