Description

Technical Field

[0001] This utility model relates to the field of cutting tools, specifically a gear shaping cutter. Background Technology

[0002] Cutting tools are frequently used in machining processes and are consumables. Especially when machining complex parts, tool wear is extremely severe. Most cutting tools currently available are one-piece molded structures. Once the cutting edge is worn, in order not to affect the production quality and machining accuracy, the tool must be replaced frequently. However, for one-piece molded tools, the replacement cost is very expensive, and safety accidents can easily occur during the replacement process, leading to increased production costs and safety incidents.

[0003] Therefore, it is necessary to provide a gear shaping tool to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a gear hobbing cutter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gear shaping cutter includes a cutter body and a blade. The cutter body has a cylindrical structure with an internal cavity. The top of the cutter body is sealed, and a pressure plate is welded to the bottom of the cutter body, which also serves to seal the bottom. Limiting blocks are symmetrically arranged on the pressure plate. A telescopic cylinder is fixedly installed above the internal cavity. The telescopic rod of the telescopic cylinder is downwardly oriented, and a pressure plate is fixedly connected to the end of the telescopic rod and can move up and down with the telescopic rod. Limiting blocks are symmetrically arranged on the lower surface of the pressure plate and are inclined. The pressure plate is the same size as the pressure plate, and the limiting blocks on its surface correspond vertically. A rectangular opening is opened on one side of the lower end of the cutter body, which communicates with the internal cavity and faces the opening of the symmetrically arranged limiting blocks. The blade is rhomboid. A pressure sensor is installed inside the pressure plate. A controller is installed on the upper end of the cutter body, and the controller is electrically connected to the telescopic cylinder and the pressure sensor.

[0007] Preferably, the included angle of the symmetrically arranged limiting blocks matches the size of the blade and fits against the sidewall of the blade.

[0008] Preferably, the pressure plate has grooves on both sides, and the inner wall of the blade body has a slide rail corresponding to the grooves on the pressure plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention uses a telescopic cylinder to move the pressure plate downwards, while the limiting block secures the blade more stably to the blade body. Simultaneously, when changing the blade, the telescopic cylinder moves the pressure plate upwards, making blade replacement faster and safer. Ultimately, this improves production efficiency and reduces safety hazards throughout the entire production process. Attached Figure Description

[0020] like Figure 1-6 As shown, a gear shaping cutter includes a cutter body 1 and a blade 12. The cutter body 1 has a cylindrical structure with an internal cavity 3. The top of the cutter body 1 is sealed, and a pressure plate 5 is welded to the bottom of the cutter body 1, which serves to seal the bottom. Limiting blocks 6 are symmetrically arranged on the pressure plate 5. A telescopic cylinder 2 is fixedly installed above the internal cavity 3. The telescopic rod of the telescopic cylinder 2 is set downward. The end of the telescopic rod is fixedly connected to a pressure plate 4 and can move up and down with the telescopic rod. Limiting blocks 6 are symmetrically arranged on the lower surface of the pressure plate 4 and are inclined. The pressure plate 5 is the same size as the pressure plate 4, and the limiting blocks 6 on its surface are vertically corresponding. A rectangular opening 7 is opened on one side of the lower end of the cutter body 1. The rectangular opening 7 is connected to the internal cavity 3 and is directly opposite the opening of the symmetrically arranged limiting blocks 6. The blade 12 is rhomboid. A pressure sensor 11 is installed inside the pressure plate 4. A controller 10 is installed on the upper end of the cutter body 1. The controller 10 is electrically connected to the telescopic cylinder 2 and the pressure sensor 11.

[0021] The working principle of a gear shaping cutter during blade replacement according to this utility model:

[0022] The blade body 1 has a cylindrical structure with an internal cylindrical cavity. A pressure platform 5 is fixedly installed at the bottom of the blade body 1, and the pressure platform 5 seals the bottom of the blade body 1. A rectangular opening 7 is opened on the lower side wall of the blade body 1 and communicates with the cavity. The controller 10 on the blade body 1 controls the telescopic cylinder 2 located at the top of the inner cavity 3 to move the pressure plate 4 fixedly connected to the telescopic rod vertically upward. To ensure the stability of the pressure plate 4 during movement, sliding grooves 9 are opened on both sides of the pressure plate 4, and sliding rails 8 are opened on the corresponding sides of the inner cavity 3. When the distance between the pressure plate 4 and the pressure platform 5 is greater than the thickness of the blade 12, the controller 10 controls the telescopic cylinder 2 to stop running, pushing the blade 12 horizontally from the rectangular opening 7 onto the pressure platform 5 until it fits against the limiting blocks 6 symmetrically arranged on the left and right sides of the pressure platform 5. Since the blade 12 has a rhomboid structure, in order to keep the blade 12 on a fixed path during the pushing process, the limiting blocks 6 are tilted towards each other and maintain a fixed included angle. With the corner facing the rectangular opening 7, after the blade 12 is placed, the controller 10 is activated again to control the telescopic cylinder 2 to move downward, so that the pressure plate 4 and the pressure table 5 move closer to each other. In order to prevent the blade 12 from moving horizontally during the pressing process, a limit block 6 is also set on the lower surface of the pressure plate 4 and corresponds one-to-one with the limit block 6 on the pressure table 5. Finally, the blade 12 is tightly fixed after being subjected to downward pressure. Since the pressure on different specifications of blades 12 is also different, it is necessary to control the downward pressure. Therefore, the pressure sensor 11 is installed in the pressure plate 4 to transmit electrical signals to the controller 10 in a timely manner. By setting the corresponding program for the controller 10, the pressure on the blade 12 can be more accurate and stable. Finally, the blade 12 can be installed and replaced during the entire operation, which solves the problems of expensive and inconvenient replacement of one-piece molded gear cutters and easy safety accidents, and improves production efficiency and product quality.
