Description

Technical Field

[0001] This utility model belongs to the technical field of gear hobbing machines, and in particular relates to an automatic feeding gear hobbing machine. Background Technology

[0002] The gear hobbing machine is one of the most widely used gear processing machine tools. It can cut spur gears, helical gears, worm gears, sprockets, etc. It is a gear processing machine tool that uses a hob to machine spur gears, helical gears, herringbone gears, and worm gears using the generating method.

[0003] An existing gear hobbing machine includes a frame on which a hob is mounted. A first push rod and a second push rod, extendable along their length, are horizontally mounted on both sides of the hob. The central axes of the first and second push rods are on the same straight line. A support claw is mounted on the frame to support the gear to be processed between the first and second push rods. A drive mechanism is provided between the support claw and the frame to drive the support claw to move between or away from the first and second support rods. By using the support claw, the gear to be processed can be supported between the first and second push rods instead of manually. Furthermore, the supported gear has a high level of horizontality, resulting in high precision when fixing the gear and improving the accuracy of the processed gear.

[0004] In the current gear hobbing machine, the workpiece is still placed on the support claw by manual handling during the processing. Although this method can quickly fix the workpiece by clamping both ends with a two-way push rod, it does not completely solve the many drawbacks of manual loading. Manual loading is not only inefficient, but also prone to inaccurate placement or insecure fixing due to human factors, which affects the processing accuracy and quality. Furthermore, long-term manual operation increases the labor intensity of workers, reduces production efficiency, and also poses certain safety hazards.

[0005] Therefore, in view of the above situation, there is an urgent need to develop an automatic feeding gear hobbing machine to overcome the shortcomings in current practical applications. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model embodiment is to provide an automatic feeding gear hobbing machine to solve the problems in the background technology mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automatic feeding gear hobbing machine includes a gear hobbing machine body and an automatic feeding mechanism. The automatic feeding mechanism is located on one side of the machining station on the gear hobbing machine body, and includes:

[0009] The feeding box is located on one side of the processing station on the gear hobbing machine body. The feeding box is equipped with a moving mechanism on both sides, and the feeding box has feeding holes at both ends that cooperate with the moving mechanism. The feeding hole at one end of the feeding box cooperates with the processing station on the gear hobbing machine body.

[0010] A guide block is fixed inside the feeding box. A vertically inclined guide groove is provided on one side of the guide block, and the vertical height of the guide groove gradually decreases at both ends.

[0011] A clamping mechanism, one end of which is movably mounted on one side of the moving mechanism, and the other end of which is slidably connected to the guide groove;

[0012] The cylindrical part enters the moving mechanism through the feed hole at one end of the feeding box and is located in the middle of the clamping mechanism. The moving mechanism drives the clamping mechanism to move by moving. The clamping mechanism drives the other end to rotate by sliding one end in the guide groove. The clamping mechanism clamps the cylindrical part located in the middle by rotating the other end in a central convergence manner. The clamping mechanism completes the automatic feeding of the cylindrical part by driving the cylindrical part clamped on it to move synchronously.

[0013] As a further technical solution of this utility model, the moving mechanism includes a drive control, a moving block, a feeding cylinder and a feeding hole. The drive control is fixed on the side wall of the feeding box. A moving block is fixed on the output end of the drive control. The moving block is fixedly connected to the feeding cylinder that is slidably installed in the feeding box. A feeding hole concentric with the feeding hole is opened in the middle of the feeding cylinder. A clamping mechanism is installed at one end of the feeding cylinder.

[0014] As a further technical solution of this utility model, the clamping mechanism includes a rotating component and a clamping component. One end of the rotating component is movably installed at one end of the feeding cylinder, and the other end of the rotating component is slidably connected to the guide groove. One end of the clamping component is connected to one end of the rotating component, and the other end of the clamping component is rotatably installed at one end of the feeding cylinder.

[0015] As a further technical solution of this utility model, the rotating component includes a sliding member, a telescopic member, a rotating shaft, a gear, and an annular rack. One end of the sliding member is slidably installed in the guide groove, and the other end of the sliding member is fixedly connected to one end of the telescopic member. The other end of the telescopic member is fixedly connected to the rotating shaft rotatably installed on one end of the upper feed cylinder. A gear is fixed on the rotating shaft, and the gear meshes with the annular rack rotatably installed on one end of the upper feed cylinder. The annular rack is connected to the clamping component.

[0016] As a further technical solution of this utility model, the clamping assembly includes a connecting rod, a clamping block and a pin. The clamping block is circumferentially distributed at one end of the feeding cylinder through the pin. The connecting rod is circumferentially distributed at the same distance on the annular rack. One end of the connecting rod is eccentrically rotatably connected to the clamping block.

[0017] As a further technical solution of this utility model, the clamping block adopts an arc-shaped block structure made of a material with good deformation capability.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The cylindrical part enters the moving mechanism through the feed hole at one end of the feeding box and is located in the middle of the clamping mechanism. The moving mechanism moves, which drives the clamping mechanism to move. The clamping mechanism slides at one end in the guide groove, which drives the other end to rotate. The clamping mechanism, by rotating the other end, can clamp the cylindrical part located in the middle in a central convergence manner, so that the cylindrical part can move synchronously with the clamping mechanism. It can pass smoothly through the feed hole at the other end of the feeding box without manual intervention and accurately enter the processing station on the gear hobbing machine body.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] like Figures 1 to 3 As shown, an automatic feeding gear hobbing machine provided as an embodiment of this utility model includes a gear hobbing machine body and an automatic feeding mechanism. The automatic feeding mechanism is located on one side of the processing station on the gear hobbing machine body, and the automatic feeding mechanism includes:

[0028] The feeding box 1 is located on one side of the processing station on the gear hobbing machine body. The feeding box 1 is equipped with a moving mechanism 2 on both sides, and the feeding box 1 has feeding holes 5 at both ends that cooperate with the moving mechanism 2. The feeding hole 5 at one end of the feeding box 1 cooperates with the processing station on the gear hobbing machine body.

[0029] Guide block 4, which is fixed inside the feeding box 1, has a vertically inclined guide groove 41 on one side, and the vertical height of the guide groove 41 gradually decreases at both ends.

[0030] The clamping mechanism 3 has one end movably mounted on one side of the moving mechanism 2, and the other end slidably connected to the guide groove 41.

[0031] The cylindrical part enters the moving mechanism 2 through the feed hole 5 at one end of the feeding box 1 and is located in the middle of the clamping mechanism 3. The moving mechanism 2 moves to drive the clamping mechanism 3 to move. The clamping mechanism 3 rotates by sliding one end on the guide groove 41. The clamping mechanism 3 clamps the cylindrical part located in the middle by converging in a central manner, so that the cylindrical part can move synchronously with the clamping mechanism 3. It can pass smoothly through the feed hole 5 at the other end of the feeding box 1 without manual intervention and enter the processing station on the gear hobbing machine body accurately. This automated feeding process not only eliminates the drawbacks of traditional manual feeding, such as low efficiency or easy error, but also significantly improves the processing efficiency and processing quality of the gear hobbing machine.

[0032] like Figures 1 to 3As shown, in a preferred embodiment of the present invention, the moving mechanism 2 includes a drive control 21, a moving block 22, a feeding cylinder 23, and a feeding hole 24. The drive control 21 is fixed on the side wall of the feeding box 1. The moving block 22 is fixed on the output end of the drive control 21. The moving block 22 is fixedly connected to the feeding cylinder 23, which is slidably installed in the feeding box 1. The feeding cylinder 23 has a feeding hole 24 concentric with the feeding hole 5 in the middle. A clamping mechanism 3 is installed at one end of the feeding cylinder 23.

[0033] In this embodiment, the drive control 21 can move the moving block 22 by telescoping. The moving block 22 moves the feeding cylinder 23 within the feeding box 1. The feeding cylinder 23 moves the clamping mechanism 3, enabling the clamping mechanism 3 to automatically transfer cylindrical parts by moving and cooperating with the guide groove 41. This achieves automatic feeding of two cylindrical parts, allowing them to pass smoothly through the feed hole 5 at the other end of the feeding box 1 without manual intervention and accurately enter the processing station on the gear hobbing machine body. This automated feeding process not only eliminates the drawbacks of traditional manual feeding, such as low efficiency or easy errors, but also significantly improves the processing efficiency and quality of the gear hobbing machine.

[0034] In a preferred embodiment, the drive control 21 preferably adopts a telescopic structure consisting of a hydraulic telescopic cylinder and a telescopic rod.

[0035] like Figures 1 to 3 As shown, in a preferred embodiment of the present invention, the clamping mechanism 3 includes a rotating component 31 and a clamping component 32. One end of the rotating component 31 is movably mounted on one end of the feeding cylinder 23, and the other end of the rotating component 31 is slidably connected to the guide groove 41. One end of the clamping component 32 is connected to one end of the rotating component 31, and the other end of the clamping component 32 is rotatably mounted on one end of the feeding cylinder 23.

[0036] In this embodiment, the rotating component 31 and the clamping component 32 move synchronously with the feeding cylinder 23. The rotating component 31, in its moving state, can rotate by cooperating with the guide groove 41. The rotating component 31 drives the clamping component 32 to rotate, so that the clamping component 32 clamps the cylindrical part located in the middle in a central convergence manner. This allows the clamping component 32, in its moving state, to move the cylindrical part it clamps, completing the automatic transfer of the cylindrical part. This achieves automatic feeding of two cylindrical parts, which can pass smoothly through the feed hole 5 at the other end of the feeding box 1 without manual intervention and accurately enter the processing station on the gear hobbing machine body. This automated feeding process not only eliminates the drawbacks of traditional manual feeding, such as low efficiency or easy error, but also significantly improves the processing efficiency and processing quality of the gear hobbing machine.

[0037] like Figures 1 to 3 As shown, in a preferred embodiment of the present invention, the rotating assembly 31 includes a sliding member 311, a telescopic member 312, a rotating shaft 313, a gear 314, and an annular rack 315. One end of the sliding member 311 is slidably installed in the guide groove 41, and the other end of the sliding member 311 is fixedly connected to one end of the telescopic member 312. The other end of the telescopic member 312 is fixedly connected to the rotating shaft 313, which is rotatably installed on one end of the feeding cylinder 23. The gear 314 is fixed on the rotating shaft 313, and the gear 314 meshes with the annular rack 315, which is rotatably installed on one end of the feeding cylinder 23. The annular rack 315 is connected to the clamping assembly 32.

[0038] like Figures 1 to 3 As shown, in a preferred embodiment of the present invention, the clamping assembly 32 includes a connecting rod 321, a clamping block 322 and a pin 323. The clamping block 322 is circumferentially distributed at one end of the feeding cylinder 23 via the pin 323. The connecting rod 321 is circumferentially distributed at an equal distance on the annular rack 315. One end of the connecting rod 321 is eccentrically rotatably connected to the clamping block 322.

[0039] like Figures 1 to 3 As shown, in a preferred embodiment of the present invention, the clamping block 322 preferably adopts an arc-shaped block structure made of a material with good deformation capability. This allows the clamping block 322 to drive the cylindrical part to move synchronously during the clamping process, so that the clamping and synchronous movement do not interfere with each other, thereby realizing the automatic transfer of the cylindrical part.

[0040] In this embodiment, the rotating assembly 31 and the clamping assembly 32 move synchronously with the upper feed cylinder 23. The sliding member 311, in its moving state, engages with the guide groove 41 to drive the telescopic member 312 to deflect. The telescopic member 312 drives the rotating shaft 313 to rotate, which in turn drives the gear 314 on it to rotate. The gear 314 drives the annular rack 315 to rotate. The annular rack 315, through rotation and engagement with the connecting rod 321, drives the clamping block 322 to rotate around its center on the upper feed cylinder 23, thereby... The clamping block 322, which moves synchronously with the feeding cylinder 23, can move the clamped cylindrical part, thereby completing the automatic transfer of the cylindrical part. This achieves automatic feeding of two cylindrical parts, which can pass smoothly through the feeding hole 5 at the other end of the feeding box 1 without manual intervention and accurately enter the processing station on the gear hobbing machine body. This automated feeding process not only eliminates the drawbacks of traditional manual feeding, such as low efficiency or easy error, but also significantly improves the processing efficiency and processing quality of the gear hobbing machine.

[0041] In a preferred embodiment, the slider 311 is preferably a slider;

[0042] The telescopic component 312 preferably adopts a telescopic rod with elastic telescopic function.

[0043] The working principle of this utility model is as follows:

[0044] The drive control 21 can move the moving block 22 by telescoping, which in turn moves the feeding cylinder 23 within the feeding box 1. The feeding cylinder 23 drives the rotating assembly 31 and the clamping assembly 32 to move synchronously. The sliding member 311, in its moving state, can drive the telescoping member 312 to deflect by engaging with the guide groove 41. The telescoping member 312 drives the rotating shaft 313 to rotate, which in turn drives the gear 314 on it to rotate. The gear 314 drives the ring rack 315 to rotate, and the ring rack 315, through rotation and engagement with the connecting rod 321, can drive the clamping block 322 to move within the feeding box 1. The material cylinder 23 rotates in a central convergence manner, thereby clamping the cylindrical parts. The clamping block 322, which moves synchronously with the material cylinder 23, can drive the clamped cylindrical parts to move, thereby completing the automatic transfer of the cylindrical parts. This realizes the automatic feeding of two cylindrical parts. They can pass smoothly through the feed hole 5 at the other end of the feeding box 1 without manual intervention and accurately enter the processing station on the gear hobbing machine body. This automated feeding process not only eliminates the drawbacks of traditional manual feeding, such as low efficiency or easy error, but also significantly improves the processing efficiency and processing quality of the gear hobbing machine.

[0045] The above describes the working principle of this automatic feeding gear hobbing machine.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
