[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] A gear and worm gear machining positioning device, as shown in the figure, includes a worktable 1. The worktable 1 has a rotating assembly 11 and a positioning assembly 12. Specifically, the positioning assembly 12 includes a positioning block 121 and a clamping block 122 located on one side of the positioning block 121. The clamping block 122 is detachably connected to the positioning block 121. The clamping block 122 has a groove 123 for accommodating one end of a part. During installation, the operator can select a clamping block 122 with a suitable groove 123 size according to the diameter of the part to be machined. In this embodiment, the shape of the groove 123... Without limitation, the groove 123 can be circular or square. The groove 123 only needs to be adapted to the shape of the part to be processed and ensure that the part is clamped during the processing. By setting a detachable clamping block 122, the worm gear does not need to be pre-drilled for positioning, saving the additional drilling process. The detachable connection method makes it easy to replace the clamping block 122 of different specifications according to the shape and size of the part, improving the versatility and flexibility of the device. At the same time, the design of the groove 123 can ensure the stable embedding of one end of the part, providing a reliable positioning basis for subsequent processing.

[0026] The rotating assembly 11 includes a rotating block 111. A motor 15 is provided on the worktable 1 to drive the rotating block 111 to rotate. The rotating block 111 is detachably connected to the output shaft of the motor 15. The detachable connection method facilitates the replacement of rotating blocks 111 of different specifications according to processing needs, improving the versatility and adaptability of the device. Specifically, the rotating block 111 is provided with several clamping arms 113, and a space for accommodating the other end of the part is formed between the clamping arms 113. Nuts 112 are sleeved on the clamping arms 113. When the nuts 112 rotate away from the rotating block 111, the movable ends of the clamping arms 113 move closer to each other, thereby clamping the other end of the part. This clamping method can flexibly adjust the clamping force according to the diameter of the part, ensuring that the part will not loosen during processing, thus improving the stability and reliability of processing.

[0027] Both sides of the positioning block 121 are rotatably connected to retaining arms 124, and the two retaining arms 124 are symmetrically arranged. The clamping block 122 has a groove 1221 for accommodating the movable end of the retaining arm 124. When the retaining arm 124 is inserted into the groove 1221, the retaining arm 124 abuts against the bottom surface of the groove 1221, and the positioning block 121 and the clamping block 122 are fixed together. This design, through the cooperation of the retaining arm 124 and the groove 1221, further enhances the connection stability between the positioning block 121 and the clamping block 122, preventing the clamping block 122 from shifting due to vibration or other factors during processing, thereby ensuring the accuracy of part positioning. Furthermore, the retaining arm 124 has an arc-shaped groove 1242, and an arc-shaped piece 1243 extends upward from one side of the arc-shaped groove 1242. The retaining arm 124 is provided with an anti-loosening pad 1244, and the retaining arm 124 is inserted into the groove. At position 1221, the anti-loosening washer 1244 is located between the groove 1221 and the retaining arm 124. The anti-loosening washer 1244 is made of rubber material. The rubber material anti-loosening washer 1244 has good elasticity and anti-slip properties, which can effectively prevent the bolt 126 from loosening due to vibration during processing, thereby ensuring the long-term stable operation of the device. The design of the arc groove 1242 and the arc plate 1243 makes it easier for the operator to apply force to the retaining arm 124, improving the efficiency of disassembling and assembling the clamping block 122.

[0028] Furthermore, a number of bolts 126 are detachably connected within the groove 1221, and the retaining arm 124 has through holes 1241 for accommodating the bolts 126. Specifically, four bolts 126 are symmetrically arranged within the groove 1221. This symmetrical arrangement of bolts 126 can apply pressure evenly, making the retaining arm 124 more firmly fixed within the groove 1221, further improving the stability of the device. At the same time, the detachable connection method facilitates the replacement and maintenance of the bolts 126, extending the service life of the device.

[0029] The workbench 1 is also equipped with a machining component and a spraying system. Specifically, the machining component includes a machining block 13, and infrared probes 131 are symmetrically arranged on both sides of the machining block 13. The spraying system includes at least two sets of spray pipes 14, which are respectively installed on the side of the workbench 1 closest to the rotating component 11 and the positioning component 12. The infrared probes 131 are signal connected to the spray pipes 14. When the machining block 13 moves toward the rotating block 111 or the positioning block 121, the infrared probes 131 detect that the distance is less than a set threshold, triggering the corresponding spray pipe 14 to open and spray coolant directionally to the cutting area. This design can automatically control the opening of the spray pipes 14 according to the actual position of the machining block 13, ensuring that the coolant can be accurately sprayed onto the cutting area, improving the cooling effect, extending the tool life, and washing away the chips produced by machining, thus ensuring the quality of the machined parts.

[0030] Furthermore, the nozzle angle of the spray pipe 14 is adjustable, and the spray system is connected to a flow control valve. The flow control valve dynamically adjusts the coolant flow rate according to the spacing detected by the infrared probe. The adjustability of the nozzle angle allows the coolant to be flexibly adjusted according to different processing positions and angles, further improving the uniformity and effectiveness of cooling. The dynamic adjustment function of the flow control valve can adjust the coolant flow rate in real time according to the actual needs during the processing, avoiding coolant waste and ensuring the stability and reliability of the processing process.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
