[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, such as Figure 1-5 As shown, a hinge pin rapid tapping machine includes an operating frame 1, an inner box 11 fixedly connected to the inner surface of the operating frame 1, a tapping mechanism 12 arranged above the operating frame 1, a feeding component 2 arranged on the top of the operating frame 1, and a collecting component 3 arranged inside the inner box 11.

[0026] The aforementioned tapping mechanism 12 includes a support frame, a hydraulic cylinder, an electric push rod, a moving plate, a servo motor, and a tap. When the device is working, the electric push rod is turned on to drive the moving plate to move back and forth at the bottom of the support frame. When the moving plate moves to the top of the fixed hinge pin, the hydraulic cylinder is turned on to drive the servo motor to move downward so that the tap fixed at the output end of the servo motor contacts the top of the hinge pin. The servo motor is turned on to drive the tap to rotate and tap the hinge pin.

[0027] Specifically, in order to enable the device to tap multiple hinge pins at once, refer to... Figure 2 and Figure 3In this embodiment, the feeding assembly 2 includes a connecting frame 21. The bottom of the connecting frame 21 is fixedly connected to the top of the operating frame 1. A threaded rod 211 is rotatably connected to the inner wall of the connecting frame 21. A motor 212 is fixedly connected to the left end of the connecting frame 21. The output end of the motor 212 is fixedly connected to the left end of the threaded rod 211. A moving block 213 is threadedly connected to the outer surface of the threaded rod 211.

[0028] Further reading Figure 2 In this embodiment, the top of the connecting frame 21 has two sliding grooves, and the inner walls of the two sliding grooves are slidably connected to the slide plate 22. The top of the slide plate 22 is fixedly connected to two fixed seats 23, and the bottom of the slide plate 22 is fixedly connected to the top of the moving block 213.

[0029] Further, referring to the figure, in this embodiment, the two fixing seats 23 are arranged symmetrically to the left and right of the center of the slide plate 22. The top of the fixing seat 23 is provided with several insertion holes, and the top of the fixing seat 23 contacts the clamping plate 231.

[0030] Further reading Figure 3 In this embodiment, a threaded rod 233 is rotatably connected to the inner wall of the clamping plate 231. A rotating block 234 is fixedly connected to one end of the threaded rod 233 away from the center of the sliding plate 22. A circular recess is provided on the side of the fixing seat 23 near the clamping plate 231. The outer surface of the threaded rod 233 is threadedly connected to the inner wall of the circular recess. Two round rods 232 are fixedly connected to one end of the clamping plate 231 near the fixing seat 23. The outer surfaces of the two round rods 232 are slidably connected to the inner wall of the fixing seat 23.

[0031] During implementation, when tapping the hinge pins is required, multiple hinge pins are first inserted into several holes opened on the top of the two fixed seats 23. After the hinge pins are inserted, the rotating block 234 is rotated clockwise to drive the threaded rod 233 to rotate within the inner wall of the fixed seat 23. Since the threaded rod 233 is threaded to the inner wall of the fixed seat 23, when the threaded rod 233 rotates clockwise, it will drive the clamping plate 231 to move towards the fixed seat 23. When the clamping plate 231 moves to a certain position, its surface can make close contact with the surface of the fixed seat 23 and the outer surfaces of the hinge pins, so that the hinge pins can be fixed inside the holes opened on the top of the fixed seat 23. When the motor 212 is turned on, it drives the threaded rod 211 to rotate. As the threaded rod 211 rotates clockwise, it moves the sliding plate 22 towards the center of the operating frame 1 via the moving block 213. When the sliding plate 22 moves, it drives the fixed seat 23 to move to the bottom of the tapping mechanism 12. The tapping mechanism 12 can gradually tap several hinge pins inserted into the insertion hole, so that the device can tap multiple hinge pins at one time. This not only shortens the overall processing time and improves the processing speed of the device, but also eliminates the need for operators to frequently load and unload hinge pins, greatly reducing the workload, reducing fatigue caused by repeated loading and unloading operations, and lowering the probability of operational errors.

[0032] Example 2: This example sets up a collection component based on Example 1.

[0033] Specifically, in order to achieve the goal of collecting the iron filings generated during tapping inside the collection box, refer to... Figure 4 and Figure 5 In this embodiment, the collection component 3 includes a guide plate 31, and a sliding block 342 is fixedly connected to both the left and right ends. Four connecting blocks 34 are fixedly connected to the inner wall of the inner box 11. A fixing rod 341 is fixedly connected to the inner surface of each of the four connecting blocks 34, and the outer surface of each of the four fixing rods 341 is slidably connected to the inner wall of the sliding block 342 on the same side.

[0034] Further reading Figure 4 In this embodiment, springs 343 are sleeved on the outer surfaces of the four fixed rods 341, the tops of the four springs 343 are fixedly connected to the bottom of the sliding block 342 on the same side, and the bottoms of the four springs 343 are fixedly connected to the inner surface of the connecting block 34 on the same side.

[0035] Further reading Figure 5In this embodiment, the bottom of the inner box 11 is fixedly connected to two slide rails 32, and the inner walls of the two slide rails 32 are slidably connected to a collection box 321. The inner wall of the inner box 11 is rotatably connected to a rotating shaft 33. The outer right surface of the rotating shaft 33 and the outer right surface of the threaded rod 211 are connected to a belt 331 for transmission. The left end of the rotating shaft 33 is fixedly connected to a striking block 332.

[0036] During implementation, most of the iron filings generated during the machining of the hinge pin fall onto the top of the guide plate 31 and roll down into the collection box 321. Simultaneously, the rotation of the threaded rod 211 drives the rotating shaft 33 via the belt 331. The rotation of the shaft 33 causes the striking block 332 to rotate, striking the guide plate 31 and causing it to move downwards. As the guide plate 31 moves downwards, it causes the sliding block 342 to slide downwards on the outer surface of the corresponding fixed rod 341. The sliding block 342 compresses the spring 343, causing it to... When the striking block 332 rotates to a certain angle, it will separate from the top of the guide plate 31. The deformed spring 343 will push the guide plate 31 to move upward and return to its original position. Through the continuous rotation of the striking block 332, the guide plate 31 will move up and down quickly, which can prevent iron filings from accumulating on the top of the guide plate 31. This not only helps to keep the work area clean and tidy and improves work efficiency, but also brings a good psychological feeling to the operators. Moreover, iron filings may cause fires under certain conditions. Collecting and properly storing the iron filings can greatly reduce the risk of fire caused by iron filings.

[0037] The working principle of this utility model is as follows: When tapping the hinge pins is required, multiple hinge pins are first inserted into several holes opened on the top of the two fixed seats 23. After the hinge pins are inserted, the rotating block 234 is rotated clockwise to drive the threaded rod 233 to rotate in the inner wall of the fixed seat 23. Since the threaded rod 233 is threadedly connected to the inner wall of the fixed seat 23, when the threaded rod 233 rotates clockwise, it will drive the clamping plate 231 to move towards the fixed seat 23. When the clamping plate 231 moves to a certain position, the surface of the clamping plate 231 can make close contact with the surface of the fixed seat 23 and the outer surface of several hinge pins, so that the hinge pins can be fixed in the holes opened on the top of the fixed seat 23. When the motor 212 is turned on, the threaded rod 211 rotates. As the threaded rod 211 rotates clockwise, it moves the sliding plate 22 towards the center of the operating frame 1 via the moving block 213. When the sliding plate 22 moves, it moves the fixed seat 23 to the bottom of the tapping mechanism 12. The tapping mechanism 12 can gradually tap several hinge pins inserted into the insertion hole, allowing the device to tap multiple hinge pins at once. This not only shortens the overall processing time and increases the processing speed of the device, but also eliminates the need for operators to frequently load and unload hinge pins, greatly reducing workload, fatigue caused by repeated loading and unloading operations, and lowering the probability of operational errors.

[0038] Most of the iron filings generated during the machining of the hinge pin fall onto the top of the guide plate 31 and roll down into the collection box 321. Simultaneously, the rotation of the threaded rod 211 drives the rotating shaft 33 via the belt 331. The rotation of the shaft 33 causes the striking block 332 to rotate, striking the guide plate 31 and causing it to move downwards. This downward movement of the guide plate 31 causes the sliding block 342 to slide downwards on the outer surface of the corresponding fixed rod 341. The sliding block 342 compresses the spring 343, causing it to deform. After the striking block 332 rotates to a certain angle, it will separate from the top of the guide plate 31. The deformed spring 343 will push the guide plate 31 to move upward and return to its original position. Through the continuous rotation of the striking block 332, the guide plate 31 will move up and down quickly, which can prevent iron filings from accumulating on the top of the guide plate 31. This not only helps to keep the work area clean and tidy and improves work efficiency, but also brings a good psychological feeling to the operators. Moreover, iron filings may cause fires under certain conditions. Collecting and properly storing the iron filings can greatly reduce the risk of fire caused by iron filings.

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 claims.
