Technical Field

[0001] This utility model relates to the field of hobbing machine technology, specifically a hobbing machine structure that allows for blade replacement without disassembling the shaft. Background Technology

[0002] Hobbing machines are widely used in industrial production for cutting and processing various materials. During the use of a hobbing machine, the blade, as the part that directly participates in the work, is prone to wear and damage due to frequent contact with the workpiece, and needs to be replaced regularly.

[0003] Currently, when changing blades on traditional hobbing machines, it is usually necessary to disassemble the entire cutter shaft. This process is often quite cumbersome. Disassembling the cutter shaft requires the use of various specialized tools, and the cutter shaft is installed quite securely in the equipment. The disassembly process requires operators to have certain professional skills and experience, making the operation quite difficult. Therefore, those skilled in the art have provided a hobbing machine structure that allows blade replacement without disassembling the shaft, in order to solve the problems mentioned in the background art. Utility Model Content

[0007] As a further improvement of this utility model: the outer surface of the cutter shaft is connected to two limiting blocks, and the outer surface of the two limiting blocks is provided with a ring-shaped limiting groove, and a cutting blade is engaged inside each limiting groove.

[0008] As a further improvement of this utility model: each of the fixed plates in the group has a ring of triangular plates installed on one side of each other by screws, and the outer surface of each triangular plate is in contact with the cutting blade.

[0009] As a further improvement of this utility model: each set of triangular plates has a groove on one side that is close to each other, each set of grooves has a round rod inside, each groove has a spring connected to its inner wall, and the ends of each set of springs that are far apart from each other are in contact with the round rod.

[0010] As a further embodiment of this invention: the two gears mesh with each other, and the output end of the drive motor is connected to one of the rotating rods via a coupling.

[0011] As a further improvement of this utility model: each set of rotating rods has a mounting plate connected to one end of each group that is close to the other, and the mounting plates of each group are connected to a fixing plate by screws on one side that is close to the other.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This is a rotary cutter structure that allows for blade replacement without disassembling the shaft. The cutting blade is positioned by the limiting groove of the limiting block and fixed with a triangular plate and screws. Loosening the screws allows the triangular plate to be removed for blade replacement, greatly simplifying the operation process, saving downtime for maintenance, and improving production efficiency. The spring and round rod form an elastic clamping structure to ensure that the cutting blade is stably attached to the cutter shaft, preventing shaking during operation from affecting processing accuracy, while also reducing blade wear and extending service life. The drive motor drives the rotary cutter mechanism through gear transmission. Two sets of rotary cutters work together, and the combination of a stable mounting plate and bearing connection ensures smooth operation of the equipment and improves cutting quality.

Detailed Implementation

[0016] Please see Figures 1-5 In this embodiment of the utility model, a roller cutter structure that allows for blade replacement without disassembling the shaft includes a roller cutter mechanism 1 and two vertical beams 2. Two bearings 3 are embedded on the side of the two vertical beams 2 that are close to each other. A rotating rod 4 is connected to the inner ring of each bearing 3. A connecting rod 5 is connected to the outer surface of each of the two rotating rods 4. A gear 6 is connected to the outer surface of each of the two connecting rods 5. A drive motor 7 is installed on the right side of one of the vertical beams 2. The overall structure is compact, and the base 10 and support plate 8 enhance the stability of the equipment. It is suitable for cutting various materials and has both high efficiency and practicality.

[0017] The rolling cutter mechanism 1 includes two sets of fixing plates 101. Each set of fixing plates 101 has a cutter shaft 102 connected to one side of each other. Two limiting blocks 103 are connected to the outer surface of the cutter shaft 102. The outer surface of each limiting block 103 is provided with a ring-shaped limiting groove 104. A cutting blade 105 is locked inside each limiting groove 104. A ring-shaped triangular plate 106 is installed on one side of each set of fixing plates 101 by screws. The outer surface of each triangular plate 106 is in contact with the cutting blade 105. This not only makes it convenient for people to disassemble and replace the cutting blade 105, but also makes the cutting blade 105 more stable during operation.

[0018] Each set of triangular plates 106 has a groove 107 on one side that is close to each other. A round rod 108 is provided inside each set of grooves 107. A spring 109 is connected to the inner wall of each groove 107. The ends of each set of springs 109 that are far apart from each other are in contact with the round rod 108. Two gears 6 mesh with each other. The output end of the drive motor 7 is connected to one of the rotating rods 4 through a coupling. A mounting plate 11 is connected to one side that is close to each other in each set of rotating rods 4. The sides of each set of mounting plates 11 that are close to each other are connected to a fixing plate 101 by screws. The bottom surfaces of the two vertical beams 2 are connected to a support plate 8. The bottom surface of the support plate 8 is connected to two vertical plates 9. The bottom surfaces of the two vertical plates 9 are connected to a base 10. This not only provides effective support for the equipment, but also greatly increases the stability of the cutting blade 105, thereby resulting in higher quality parts cut out.

[0019] The working principle of this utility model is as follows: First, people place the equipment in the usage position and connect the power supply. Then, the drive motor 7 is started. The drive motor 7 drives one of the rotating rods 4 to rotate through the coupling. The rotating rod 4 is driven by the meshing of the gear 6, so that the other rotating rod 4 rotates synchronously in the opposite direction. The rotating rod 4 drives the fixing plate 101 of the roller mechanism 1 to rotate through the mounting plate 11, thereby causing the cutter shaft 102 and the cutting blade 105 to rotate, so as to realize the cutting operation. When the cutting blade 105 needs to be replaced, remove the screws on the fixing plate 101, remove the triangular plate 106, and the round rod 108 will release the cutting blade 105 under the elastic force of the spring 109, so that the old blade can be taken out from the limiting groove 104 of the limiting block 103.

[0020] After installing the new blade, reset the triangular plate 106 and tighten the screw. The spring 109 is compressed, causing the round rod 108 to fix the cutting blade 105. During the replacement of the cutting blade 105, it is not necessary to disassemble the blade shaft 102 and the rotating rod 4.
