Technical Field

[0001] The utility model relates to the technical field of angle grinding devices, in particular to an angle grinding device for gear manufacturing. Background Technique

[0002] Spiral bevel gears, namely spiral conical gears, are commonly used for the movement and power transmission between two intersecting shafts. At present, the processing process of spiral bevel gears generally includes three links: hot die forging, cold finishing and machining. Among them, hot die forging and cold finishing can complete the basic contour of the product, and machining uses cutting tools to cut the tooth part of the bevel gear to complete the final forming of the tooth part;

[0003] Most of the existing gear angle grinding devices first fix a positioning shaft in the middle of the gear, and then fix the gear through a three-jaw chuck. When the gear processing is completed, the positioning shaft needs to be disassembled, which is not only troublesome to operate, but also requires temporary taking of the positioning shaft, and has high limitations in use.

Detailed description of the specific implementation

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 3 , an angle grinding device for gear manufacturing of the present invention includes a processing table 1, a gear workpiece 6, and a processing component. A central hole is provided in the middle position of the gear workpiece 6, and a clamping groove 12 is provided on the inner wall of the central hole. The processing component can process the gear workpiece 6. A second motor 7 is fixedly arranged at the lower end of the processing table 1. A bearing plate 8 is provided above the processing table 1. A rotating shaft connecting the bearing plate 8 is provided at the output end of the second motor 7. A limiting column 11 passing through the central hole is provided at the upper end of the bearing plate 8. A clamping block 13 cooperating with the clamping groove 12 is provided at the bottom of the limiting column 11. A positioning ring 15 and a limiting ring 14 are provided on the limiting column 11. The limiting ring 14 is located above the positioning ring 15. A positioning block 16 for limiting the gear workpiece 6 is provided on the positioning ring 15. The limiting ring 14 can limit the positioning ring 15, and the limiting ring 14 is threadedly connected to the limiting column 11;

[0023] The processing component includes a pusher 2, a lifter 3, and a first motor 4. The pusher 2 is fixed above the processing table 1. The lifter 3 is fixed at the output end of the pusher 2. The first motor 4 is fixed at the output end of the lifter 3. A cutting tool 5 for processing the gear workpiece 6 is provided at the output end of the first motor 4;

[0024] In this structure, the gear workpiece 6 is fixed on the processing table 1. Starting the pusher 2 can move the lifter 3. Starting the lifter 3 can make the first motor 4 drive the cutting tool 5 to descend. Starting the first motor 4 can make the cutting tool 5 rotate, and thus the gear workpiece 6 can be cut and processed. The type of the cutting tool 5 is not limited here. The pusher 2 and the lifter 3 can both adopt telescopic cylinders;

[0025] When it is necessary to fix the gear workpiece 6, first, the limiting column 11 is passed through the center hole on the gear workpiece 6, and the clamping block 13 is passed through the clamping groove 12. At this time, the gear workpiece 6 will not rotate on the limiting column 11, so that the gear workpiece 6 can be stably placed on the supporting plate 8. Further, the positioning ring 15 and the limiting ring 14 are successively mounted on the limiting column 11, so that the positioning block 16 contacts the gear workpiece 6, and then the limiting ring 14 is rotated. Through the action of the threaded structure, the limiting ring 14 can be fixed on the limiting column 11, and the limiting ring 14 can provide a pressure to the positioning ring 15, so that the positioning block 16 can provide a pressure to the gear workpiece 6 on the supporting plate 8, so that the gear workpiece 6 can be placed on the supporting plate 8 more firmly. This process does not require the positioning shaft to be assembled on the gear workpiece 6, and is easy to operate with low limitations during use.

[0026] Furthermore, two positioning blocks 16 are symmetrically arranged on the outer wall of the positioning ring 15 , so that the gear workpiece 6 can be placed on the bearing plate 8 more firmly.

[0027] The lack of stress points on the limiting ring 14 will make the limiting ring 14 difficult to operate. Two toggle blocks are symmetrically arranged on the outer wall of the limiting ring 14, which can provide multiple stress points on the limiting ring 14 and make the limiting ring 14 easy to operate.

[0028] Furthermore, the limit column 11, the limit ring 14 and the positioning ring 15 are all made of metal, and the limit column 11, the limit ring 14 and the positioning ring 15 can be made of stainless steel. Stainless steel has the advantages of high hardness and strong corrosion resistance, which can make the limit column 11, the limit ring 14 and the positioning ring 15 not easily damaged.

[0029] Furthermore, the positioning ring 15 and the positioning block 16 may be an integrated structure.

[0030] The lack of a supporting structure at the bearing plate 8 will cause the impact force received by the gear workpiece 6 to be directly transmitted to the rotating shaft, which will affect the stability of the bearing plate 8 when in use. A plurality of support rods 9 are provided at the lower end of the bearing plate 8, and a plurality of ball bearings 10 contacting the processing table 1 are provided at the bottom end of the support rods 9. When the bearing plate 8 rotates, the ball bearings 10 will slide on the processing table 1. The support rods 9 can provide a supporting structure at the bearing plate 8, so that the impact force received by the gear workpiece 6 will not be directly transmitted to the rotating shaft, thereby improving the stability of the bearing plate 8 when in use.

[0031] In the description in this article, it should be noted that relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.
