Description

Technical Field

[0001] The present invention belongs to the technical field of gear ring processing equipment, and particularly relates to a gear ring fixing device for machining the inner hole of a gear ring. Background Art

[0002] As a basic and important mechanical component, the gear ring is used in multiple aspects such as power transmission, torque conversion, and starting assistance. Whether it is an automobile engine or a complex industrial equipment, the gear ring plays an irreplaceable role. And the inner hole machining in gear ring machining is an important part, and its accuracy and quality directly affect the performance, reliability, and service life of the entire gear transmission system.

[0003] Most of the positioning devices of traditional gear ring inner hole machining equipment use the external teeth of the gear ring to be drilled for fixation. This one-way fixation may cause deformation of the gear ring to be machined, affecting the quality of the gear ring. The traditional gear ring fixing device needs to position once for each hole drilled during the drilling process. It has little impact on the machining of a single gear ring, but generally the inner hole machining of gear rings is mostly batch machining of the same model, which greatly affects the production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a gear ring fixing device for machining the inner hole of a gear ring. The present invention can realize the two-way clamping and fixing of the gear ring to be machined inside and outside, effectively prevent the gear ring from deforming when being fixed, and the limiting component can also fix the end face of the gear ring, effectively preventing the gear ring from vibrating during the machining process and affecting the drilling effect of the gear ring, improving the machining quality of the gear ring. And during the machining process, when the drilling component rises, it can drive the gear ring to be machined to rotate a certain angle, so that the gear ring drilling can be continuously processed, effectively improving the production efficiency.

Then the second lifting rod 61 descends, and the drilling component 63 can continue to drill the to-be-processed gear ring 7, finally realizing the continuous processing of the drilling component 63 and improving the production efficiency.

[0068] As Figure 1 - Figure 14 As shown in the figure, a plurality of second clamping blocks 22 are slidably connected to the lower chuck 2, and clamping teeth 221 are fixedly connected to the tops of the second clamping blocks 22.

[0069] In this embodiment, when the second clamping blocks 22 slide inwards on the lower chuck 2, the clamping teeth 221 can be attached to the outer edge of the to-be-processed gear ring 7, realizing the clamping and fixing of the to-be-processed gear ring 7.

Cooperating with the setting of the anti-slip wheels 411, the rotation of the lower chuck 2 can drive the rotation of the to-be-processed gear ring 7.

[0070] Working principle:

[0071] When working, the upper chuck 4 is started first, and the first clamping block 41 moves toward the outer edge of the upper chuck 4, so that the anti-slip wheel 411 can fit with the inner wall of the gear ring 7 to be processed, thereby clamping the gear ring 7 to be processed, and then the material transport component 3 is started, and the first lifting rod 31 can drive the upper chuck 4 to rise and fall and rotate, thereby driving the upper chuck 4 to move the gear ring 7 to be processed onto the lower chuck 2;

[0072] During the descent of the first lifting rod 31, the transmission gear 34 rotates forward, the transmission gear 34 rotates forward to drive the first worm 33 to rotate forward, the first worm 33 rotates forward to drive the first transmission gear ring 511 to rotate forward, the first transmission gear ring 511 drives the turntable 51 to rotate forward, the turntable 51 rotates forward to drive the arc rack 512 to rotate forward, the arc rack 512 rotates forward to drive the driven gear 521 to rotate forward, the driven gear 521 rotates forward to drive the limit plate 52 to expand from the upper chuck 4, so as to limit the end face of the gear ring 7 to be processed;

[0073] The second clamping block 22 slides inward on the lower chuck 2 to make the clamping teeth 221 fit with the outer edge of the gear ring 7 to be processed, so as to achieve the clamping and fixing of the gear ring 7 to be processed. In cooperation with the upper chuck 4, the gear ring 7 to be processed can be clamped and fixed in both directions inside and outside, so that the force on the gear ring 7 to be processed is uniform, and the gear ring is effectively prevented from being deformed when the gear ring is fixed. The limiting plate 52 can limit the gear ring 7 to be processed from the upper end surface of the gear ring 7 to be processed, effectively preventing vibration during the processing of the gear ring, and improving the processing quality of the gear ring. The upper chuck 4, the lower chuck 2 and the limiting assembly 5 can fix the gear rings 7 to be processed with different heights and diameters.

[0074] Then, the second lifting rod 61 is started. The lifting of the second lifting rod 61 can drive the drilling component 63 to lift. The second lifting rod 61 rotates on the second base 611 to drive the drilling component 63 to rotate, thereby realizing the lifting and moving of the drilling component 63, which is convenient for the drilling component 63 to drill the gear ring 7 to be processed.

[0075] During the drilling process, the second lifting rod 61 drives the drilling component 63 to descend and performs a drilling process on the gear ring 7 to be processed. Then, the second lifting rod 61 is lifted. The lifting of the second lifting rod 61 drives the drilling component 63 to be lifted and can drive the driving bevel rack 64 to be lifted. The lifting of the driving bevel rack 64 can drive the bevel gear 111 to rotate. The rotation of the bevel gear 111 can drive the second worm 11 to rotate. The rotation of the second worm 11 can drive the second transmission gear ring 21 to rotate. The rotation of the second transmission gear ring 21 can drive the lower chuck 2 to rotate, and the anti-skid wheel 411 on the first clamping block 41 allows the gear ring 7 to be rotated. After the gear ring 7 to be processed rotates a certain angle, the second lifting rod 61 is lowered, and the drilling component 63 can continue to perform drilling process on the gear ring 7 to be processed, and finally realize the continuous processing of the drilling component 63, thereby improving the production efficiency.

[0076] By adjusting the lifting height of the second lifting rod 61, the rotation angle of the to-be-processed gear ring 7 can be adjusted, so as to adapt to different drilling spacings and facilitate the continuous processing of the drilling component 63.

[0077] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
