Description

Technical Field

[0001] This utility model relates to the field of sprocket processing technology, specifically a positioning device for sprocket processing. Background Technology

[0002] A sprocket is a wheel with interlocking chain teeth used to mesh with precisely pitched blocks on chain links or cables. Sprockets are widely used in mechanical transmissions in industries such as chemical engineering, textile machinery, escalators, wood processing, automated parking systems, agricultural machinery, food processing, instrumentation, and petroleum.

[0003] The sprocket machining process begins with the preparation of the blank. High-quality steel is selected and forged or cut into round steel to lay the foundation for subsequent processing. The inner and outer circles, end faces and inner holes are machined by turning. The tooth profile is completed by milling or hobbing to ensure the accuracy of the tooth profile and meshing performance. A positioning device is required for positioning during the sprocket machining process.

[0004] When placing sprockets, they are usually placed directly on the worktable and then processed. However, if the sprocket needs to be adjusted during subsequent processing, the sprocket rotation needs to be adjusted multiple times, making it difficult to make quick adjustments during processing.

[0005] Therefore, a positioning device for sprocket machining is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a positioning device for sprocket processing includes a processing table 1, with a positioning post 11 fixedly connected to the center of the processing table 1; a servo motor 12 fixedly connected to the bottom of the processing table 1; a round rod 13 fixedly connected to the output end of the servo motor 12; the round rod 13 is through-hole and rotatably connected on the processing table 1; a plurality of fixing rods 14 are fixedly connected to the center of the round rod 13; an adjusting block 15 is fixedly connected to the end of the fixing rod 14; the end of the adjusting block 15 is arc-shaped; during operation, by first aligning the center of the sprocket with the positioning post 11 and then inserting it into the surface of the positioning post 11, the adjusting block 15 is positioned between the gears, and then the sprocket can be processed. When the sprocket needs adjustment, the servo motor 12 can be started. When the servo motor 12 is started, the round rod 13 rotates. When the round rod 13 rotates, the adjusting block 15 will push the sprocket to rotate. When the first adjusting block 15 is about to leave the inside of the sprocket, the next adjusting block 15 will enter between the sprocket gears, thereby controlling the rotation of the sprocket. At this time, the rest of the sprocket can be processed. By adding adjusting blocks 15, when the sprocket needs adjustment, the rotation of the round rod 13 drives the adjusting block 15 to push the sprocket, thereby quickly driving the sprocket to rotate for adjustment. Then, by relaying the adjusting blocks 15 between the sprockets, the rotation of the sprocket can be better controlled.

[0026] like Figures 1 to 2 As shown, a vertical plate 2 is fixedly connected to the top of the processing table 1; an oil bladder 21 is fixedly connected to the top of the vertical plate 2; a sponge 22 is fixedly connected to the side wall of the vertical plate 2; the sponge 22 and the adjusting block 15 are correspondingly arranged; the oil bladder 21 and the sponge 22 are connected by a hose; during operation, when the adjusting block 15 rotates, the adjusting block 15 will contact the sponge 22, which will squeeze the sponge 22. When squeezed, the oil inside the sponge 22 will seep out and adhere to the surface of the adjusting block 15. This reduces friction when the adjusting block 15 contacts the sprocket. By adding the sponge 22, the adjusting block 15 can be coated with oil when it rotates, thereby reducing friction during pushing when the adjusting block 15 contacts the sprocket, thus increasing protection and reducing friction damage.

[0027] like Figures 1 to 4 As shown, a bearing 3 is fitted onto the surface of the positioning post 11; the bearing 3 and the processing table 1 are fixedly connected; multiple rubber pads 31 are fixedly attached to the surface of the bearing 3; during operation, when the sprocket is placed on the positioning post 11, it will first contact the rubber pads 31, and then when it is pushed to rotate on the processing table 1, the rubber pads 31 will increase the frictional resistance during contact, thereby driving the bearing 3 to rotate. When the bearing 3 rotates, it will accelerate the rotation speed of the sprocket; by adding the bearing 3, the rotation of the sprocket can be accelerated by the rotation of the bearing 3, and at the same time, the rubber pads 31 can increase the frictional resistance when the sprocket rotates, thereby driving the bearing 3 to rotate.

[0028] like Figure 1 As shown, a gooseneck tube 4 is fixedly connected to the surface of the processing table 1; a nozzle 41 is fixedly connected to the top of the gooseneck tube 4; an air inlet pipe 42 is fixedly connected to the side wall of the gooseneck tube 4; the nozzle 41 and the air inlet pipe 42 are connected; during operation, when the sprocket is being processed, some debris will fall off. At this time, the debris will adhere to the surface of the sprocket. The air inlet pipe 42 can be connected to an air pump to transmit gas through the gooseneck tube 4 to the inside of the nozzle 41 and then spray it out to clean the surface of the sprocket; by adding a nozzle 41, the debris generated during the processing of the sprocket can be cleaned and detached, thereby improving the subsequent inspection effect.

[0029] like Figures 1 to 3 As shown, a square plate 5 is fixedly connected to one end of the processing table 1; a cylinder 51 is fixedly connected to the side wall of the square plate 5; a push rod 52 is fixedly connected to the output end of the cylinder 51; the push rod 52 is through-mounted and slidably connected to the square plate 5; a pressure plate 53 is fixedly connected to the end of the push rod 52; a spring telescopic rod 54 is fixedly connected to the bottom of the pressure plate 53; a connecting box 55 is fixedly connected to the bottom of the spring telescopic rod 54; a ball bearing 56 is rotatably connected inside the connecting box 55; during operation, after the sprocket is placed on the positioning column 11, the cylinder 51 can be started. When the cylinder 51 is started, it will reverse and drive the push rod 52 and the pressure plate 53 to move, thus pushing them forward. The spring telescopic rod 54 and the ball bearing 56 move upwards towards the sprocket. During this movement, the ball bearing 56 contacts the surface of the sprocket. As the sprocket rotates, it causes the ball bearing 56 to roll. When the ball bearing 56 rotates, it is pushed towards the spring telescopic rod 54 when it contacts the sprocket, thus compressing the spring telescopic rod 54. Then, it returns to its original position through the pushing force of the spring telescopic rod 54. By adding the spring telescopic rod 54 and the ball bearing 56, the compression of the spring telescopic rod 54 can increase the upper fixation when the sprocket rotates. At the same time, the rotation of the ball bearing 56 can reduce friction when it contacts the sprocket, thereby increasing the rotation speed.

[0030] like Figure 2 As shown, a guide plate 6 is fixedly connected to the side wall of the upright plate 2; the guide plate 6 is located below the sponge 22 and its surface is inclined; a collection box 61 is fixedly connected to the surface of the processing table 1; the guide plate 6 is located below the guide plate 6; during operation, when the sponge 22 applies oil to the adjusting block 15, some oil will fall onto the surface of the guide plate 6, and then move along the surface of the guide plate 6 to drip into the collection box 61, thereby collecting the oil; by adding the guide plate 6, the dripping oil can be guided into the collection box 61, thereby collecting the oil and reducing oil spillage.

[0031] Working principle: First, align the center of the sprocket with the positioning post 11 and insert it into the surface of the positioning post 11, so that the adjusting block 15 is positioned between the gears. Then, the sprocket can be machined. When the sprocket needs to be adjusted during machining, the servo motor 12 can be started. When the servo motor 12 is started, the round rod 13 rotates. When the round rod 13 rotates, the adjusting block 15 will push the sprocket to rotate. When the previous adjusting block 15 is about to leave the inside of the sprocket, the next adjusting block 15 will enter between the sprocket gears, thereby controlling the operation. The sprocket rotates, allowing for machining of the remaining parts of the sprocket. When the adjusting block 15 rotates, it contacts the sponge 22, compressing it. During this compression, oil seeps out from inside the sponge 22 and adheres to the surface of the adjusting block 15, reducing friction when the adjusting block 15 contacts the sprocket. When the sprocket is placed on the positioning pin 11, it first contacts the rubber pad 31. Subsequently, as it is pushed and rotated on the machining table 1, the rubber pad 31 increases frictional resistance during contact, thus... The bearing 3 rotates, which increases the rotation speed of the sprocket. During sprocket processing, some debris falls off and adheres to the sprocket surface. The air inlet pipe 42 can be connected to an air pump, which transmits air through the gooseneck pipe 4 to the nozzle 41, where it is then sprayed out to clean the sprocket surface. After the sprocket is placed on the positioning pin 11, the cylinder 51 can be activated. Activation of the cylinder 51 reverses the movement of the push rod 52 and pressure plate 53, causing them to push the spring telescopic rod 54 and ball bearings 56 upwards on the sprocket. Subsequently... When moving, the ball bearing 56 will contact the surface of the sprocket. At the same time, when the sprocket rotates, it will drive the ball bearing 56 to roll. When the ball bearing 56 rotates, it will be pushed towards the spring telescopic rod 54 when it contacts the sprocket, thereby compressing the spring telescopic rod 54. Then, it will be restored by the pushing force of the spring telescopic rod 54. When the sponge 22 applies oil to the adjusting block 15, some oil will fall onto the surface of the guide plate 6. Then, it will move along the surface of the guide plate 6 and drip into the collection box 61, thereby collecting the guide plate 6.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
