[0002] Gear processing refers to the process of manufacturing gears through various processing methods. Gears are a mechanical transmission device, usually composed of one or more gears, used to transmit power and speed. Gears usually have parameters such as the number of teeth, module, pressure angle, etc. These parameters determine the geometric shape and transmission characteristics of the gear.

[0003] In actual use, traditional gear processing mostly uses specific processing molds to limit the gear, such as using a disc-shaped mold with internal teeth that matches the gear workpiece to limit the gear to facilitate drilling or stamping processing. However, during this period, the disc-shaped mold has poor adaptability and usually needs to be designed and manufactured for gears of specific sizes. Therefore, different disc-shaped molds need to be customized for gears of different sizes, which increases costs and makes it difficult to quickly switch molds for gears of different sizes, limiting the flexibility of the production line. At the same time, the existing gear limiting molds make it difficult to adjust the gear workpiece in multiple directions, so that the gear needs to be disassembled and re-positioned multiple times during processing. Therefore, a limiting device for gear processing is proposed to solve the above problems. Utility Model Content

[0025] Example

[0026] Depend on Figure 1-4 Provided is a limiting device for gear processing, comprising a gear processing base 1;

[0027] The upper end surface of the gear processing base 1 is equipped with a rotating motor 2; the output end of the rotating motor 2 is connected to a rotating shaft 3; the upper end surface of the rotating shaft 3 is fitted with a gear processing disc 4, and the upper end surface of the gear processing disc 4 is integrally provided with a bearing disc 5;

[0028] The upper end surface of the carrier plate 5 is equipped with a gear limit assembly 6;

[0029] The gear limiting assembly 6 includes a limiting seat 61 arranged on the upper end surface of the carrier plate 5, and two positioning plates 62 are arranged vertically and parallel to the upper end surface of the limiting seat 61, and a positive and negative threaded rod 63 is rotatably arranged between the two positioning plates 62, and two nut sleeves 64 are meshed with the outside of the positive and negative threaded rod 63, and the two nut sleeves 64 are respectively meshed with one of the threads of the positive and negative threaded rod 63, and the outside of the two nut sleeves 64 are sleeved with a mounting seat 65;

[0030] The upper end surfaces of the two mounting seats 65 are both supported with tooth seats 68 , and the opposite sides of the two tooth seats 68 are both provided with a plurality of tooth grooves 69 .

[0031] In this embodiment, in actual processing operations, through the mutual movement and coordination of multiple components within the gear limit assembly 6, the two mounting seats 65 and the tooth seat 68 that are set in opposite sliding manner within the gear limit assembly 6 can realize rapid clamping and limiting of the gear workpiece body 8, thereby facilitating the processing of the gear workpiece body 8; compared with traditional mold limits, the limiting device of the present application can achieve precise clamping and limiting of gear workpiece bodies 8 of different diameters through precise clamping control of the two mounting seats 65, thereby achieving stability and precision of the gear workpiece body 8 during the processing process, while improving the adaptability of the equipment to gear workpiece bodies 8 of different sizes, and reducing the need to replace molds.

[0032] Furthermore, when the gear workpiece body 8 is limited on the gear limit assembly 6 and processed, through the rotation coordination of the set rotating motor 2 and the rotating shaft 3, and the connection coordination of the rotating shaft 3 and the gear processing disc 4, the set rotating motor 2 can realize rapid position adjustment of the gear workpiece body 8 through precise control, thereby improving the processing efficiency, eliminating the need for multiple disassembly and positioning, and no manual intervention is required during this period, thereby improving the speed and accuracy of the adjustment.

[0033] Furthermore, the power connection method of the rotating motor 2 is the existing technology, and its control circuit can be implemented through simple programming by technicians in this field. It belongs to the common knowledge in this field. It is only used without modification, so the control method and circuit connection are not described in detail.

[0034] Specifically, refer to Figure 3-4 , threaded holes are preset on the mounting seat 65 and the tooth seat 68 , and a screw is threadedly connected to the tooth seat 68 and passes through the tooth seat 68 until it is connected to the mounting seat 65 .

[0035] In this embodiment, by opening a tooth groove 69 on the tooth seat 68, the tooth seat 68 can match the teeth of the gear workpiece body 8, making the tooth seat 68 more accurate when clamping and limiting, which helps to ensure the stability and accuracy of the gear workpiece body 8 during the processing.

[0036] Furthermore, the tooth seat 68 can be quickly disassembled and positioned on the mounting seat 65 by means of a screw pin. In a preferred design, the tooth seat 68 can be prefabricated in a non-standard manner. In order to improve the flexibility during positioning, the user can also prefabricate the tooth seat 68 with tooth grooves 69 having different spacings. The detachable tooth seat 68 can be replaced with tooth grooves 69 having different sizes of spacings as needed to adapt to different gear workpiece bodies 8 or processing requirements. At the same time, compared with the overall customization of the mold, the non-standard prefabricated tooth seat 68 is more convenient to adjust and has a lower prefabrication cost, which improves the flexibility and versatility of the present application.

[0037] Specifically, refer to Figure 3-4 Two optical axes 66 are also installed between the two positioning plates 62. The two optical axes 66 are respectively arranged on one side of the positive and negative screw rods 63 and two linear bearings 67 are slidably assembled on the outside. The two mounting seats 65 are both provided with mounting grooves compatible with the linear bearings 67. The two mounting seats 65 are respectively sleeved on the outside of the two adjacent linear bearings 67 and connected with them.

[0038] In this embodiment, in actual use, the optical axis 66 can be used to laterally limit the mounting seat 65, so that when the forward and reverse screw rods 63 are rotating, the mounting seat 65 can slide on the outside of the forward and reverse screw rods 63 and the outside of the optical axis 66, thereby preventing the mounting seat 65 from following the rotation when the forward and reverse screw rods 63 rotate, and the linear bearing 67 arranged on the optical axis 66 can improve the smoothness of the mounting seat 65 when moving.

[0039] Furthermore, when the forward and reverse screw rods 63 are rotating, they are limited by the engagement of the two nut sleeves 64, and the lateral limitation of the mounting seat 65 by the optical axis 66 and the linear bearing 67, so that the two nut sleeves 64 can drive the mounting seat 65 to perform opposite clamping movements or reverse separation movements along the travel range of the forward and reverse screw rods 63.

[0040] Specifically, refer to Figure 1-2 A gantry 7 is mounted at the center of the upper end surface of the limiting seat 61, and a gear workpiece body 8 is supported on the upper end surface of the gantry 7. The gear workpiece body 8 is arranged between the two mounting seats 65; the opening spacing of the tooth grooves 69 is adapted to the tooth spacing of the gear workpiece body 8.

[0041] In this embodiment, the user places the gear workpiece body 8 to be processed on the upper end surface of the gantry 7 and then adjusts the gear limiting assembly 6 so that the set gear limiting assembly 6 can limit the gear workpiece body 8 to facilitate processing of the gear workpiece body 8.

[0042] Specifically, refer to Figure 1-2 A bracket seat 9 is vertically mounted on the upper end surface of the gear processing disc 4, and a cooling fan 10 is assembled in the bracket seat 9.

[0043] In this embodiment, in actual processing operations, the user can connect the cooling fan 10 to a power source to drive the cooling fan 10. Considering that friction and heat will be generated during the processing of the gear workpiece body 8, the cooling fan 10 can be provided to effectively reduce the temperature of the workpiece and avoid negative effects of overheating on the quality of the workpiece. At the same time, the heat can be quickly taken away by the cooling fan 10, which can reduce the dimensional changes of the gear workpiece body 8 caused by thermal deformation, thereby ensuring processing accuracy and quality.

[0044] Specifically, refer to Figure 1-2 A reciprocating motor 610 is installed on the side of one of the positioning plates 62 , and the output end of the reciprocating motor 610 passes through the positioning plate 62 and is connected to one end of the forward and reverse screw rod 63 .

[0045] In this embodiment, the reciprocating motor 610 is used to drive the forward and reverse screw rods 63 to perform reciprocating rotation. In actual use, the power connection method of the reciprocating motor 610 is the existing technology, and the control circuit can be realized through simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0046] The limiting device for gear processing of the utility model:

[0047] Step 1: In actual use, when the user needs to process the gear workpiece body 8, first place the gear workpiece body 8 to be processed on the upper end surface of the gantry 7, and then adjust the gear limit assembly 6 so that the set gear limit assembly 6 can limit the gear workpiece body 8, so as to facilitate the processing of the gear workpiece body 8;

[0048] Step 2: During this period, the user connects the reciprocating motor 610 to an external power source, so that the reciprocating motor 610 can drive the forward and reverse screw rods 63 to rotate. When the forward and reverse screw rods 63 rotate, they are limited by the meshing of the two nut sleeves 64, and the lateral limit of the optical axis 66 and the linear bearing 67 on the mounting seat 65, so that the two nut sleeves 64 can drive the mounting seat 65 to perform opposite clamping movements or reverse separation movements along the travel range of the forward and reverse screw rods 63.

[0049] Step 3: By installing the nut sleeve 64 and the mounting seat 65, the two mounting seats 65 can drive the tooth seat 68 to move synchronously with the nut sleeve 64. The user controls the two mounting seats 65 to move synchronously until the tooth grooves 69 on the side of the tooth seat 68 are engaged with the external teeth of the gear workpiece body 8, thereby realizing the rapid clamping of the gear workpiece body 8 by the two tooth seats 68 moving in opposite directions.

[0050] Step 4: When the gear workpiece body 8 is limited by the gear limit assembly 6, the user can then perform processing operations on the gear workpiece body 8. At the same time, when the user needs to adjust the processing position of the gear workpiece body 8, the rotating motor 2 is connected to an external power supply and its output angle is controlled. At this time, through the connection between the rotating motor 2 and the rotating shaft 3, the rotating shaft 3 can be used to drive the gear processing disc 4 to rotate, thereby realizing the rotation adjustment of the gear limit assembly 6 as a whole, thereby quickly realizing the adjustment of the processing position of the gear workpiece body 8.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
