Description

Technical Field

[0001] The utility model relates to the technical field of combined tungsten steel milling cutter equipment, and particularly relates to a tungsten steel milling cutter with staggered teeth. Background Technique

[0002] When carrying out the processing work of Qiai moxa sticks and moxa cones, it is often necessary to use Qiai moxa stick and moxa cone rolling equipment. The utility model patent with the patent application number CN202023028922.3 discloses a tungsten steel milling cutter with staggered teeth. The milling cutter and the connecting gear are detachably connected through a key and a keyway, which can drive the rod body to rotate and play a role in transmitting torque. The shock-absorbing spring is located in the middle of the rod body and is detachably connected to the rod body, reducing the vibration generated during processing and reducing the error generated when processing workpieces. The key is a cuboid block, the keyway is a cuboid groove, and the sizes of the key and the keyway are equal, which can be installed and is convenient for disassembly and storage. The outer cylindrical surface diameter of the rod body is equal to the inner diameter of the perforation, which is convenient for installation and disassembly and convenient for storage. The cutter head is a replaceable cutter head, which can process different types of workpieces and increase the application range of the milling cutter. According to the disclosed technical solution, when the existing combined tungsten steel milling cutter equipment is in use, on the one hand, when milling and processing workpieces, the cut chips are likely to get stuck between the surface of the milling cutter and the workpiece, and thus it is easy to cause scratches on the surface of the workpiece, which is not conducive to ensuring the milling quality of the workpiece. On the other hand, during work, the milling cutter is likely to fall off due to work vibration or greater external force, which is not conducive to ensuring the firmness of the installation of the milling cutter.

[0003] Therefore, how to design a tungsten steel milling cutter with staggered teeth has become the problem to be solved currently. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a tungsten steel milling cutter with staggered teeth to solve the problems put forward in the above background technique. The utility model is reasonably designed and is more convenient to use, and is suitable for the milling processing of materials.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A tungsten steel milling cutter with staggered teeth includes a cutter head and staggered teeth. One end of the cutter head is provided with a connection component. The connection component includes a connecting rod and a key surface. A fixing component is installed on the connecting rod. The fixing component includes a joint and a connecting block. A limiting component is installed inside the connecting rod and the joint. The limiting component includes a bayonet and a clamping groove. A locking component is installed inside the clamping groove. The locking component includes a pin and a spring. A water receiving component is installed outside the joint. The water receiving component includes a ring sleeve and a water pipe. A communicating component is installed inside the joint and the connecting rod. The communicating component includes a connecting port and a through port.

[0006] Further, one end of the connecting rod is integrally formed at one end of the cutter head, the staggered teeth are integrally formed at the other end of the cutter head, and the staggered teeth are evenly distributed on the cutter head.

[0007] Further, a keyway is provided at one end of the joint, the key surface is provided at the other end of the connecting rod, the key surface is stuck inside the keyway, and the connecting block is integrally formed at the other end of the joint.

[0008] Further, the clamping groove is provided inside the connecting rod, the clamping opening is provided inside the joint, and one end of the clamping pin is stuck inside the clamping groove.

[0009] Further, one end of the clamping pin is connected to the inner wall of the clamping groove through a spring, the other end of the clamping pin passes through the clamping groove and extends to the inside of the clamping opening, and the width of one end of the clamping pin is greater than the width of the other end of the clamping pin.

[0010] Further, the ring sleeve is sleeved on the outer side of the joint through a bearing, a sealing ring is clamped on the inner wall of the ring sleeve, the sealing ring is sleeved on the outer side of the joint, and the water pipe is welded to one side of the ring sleeve.

[0011] Further, the connecting port is provided inside the joint, the through port is provided inside the connecting rod and the cutter head, both ends of the connecting port are communicated with the inside of the ring sleeve, and the ring sleeve is communicated with the water pipe.

[0012] Further, the top end of the through port is communicated with the bottom of the connecting port, the bottom end of the through port is communicated with the bottom of the cutter head, and the through port is located inside the staggered teeth.

[0013] Beneficial effects: 1. When the tungsten carbide milling cutter with staggered teeth combination is working, the milling fluid is introduced into the inside of the water pipe. The milling fluid enters the inside of the ring sleeve through the water pipe, then enters the inside of the joint through the connecting port, and then flows downward through the through port to the bottom of the cutter head. By using the rotation generated by the work of the cutter head, the milling fluid flows outwards along the gaps between the staggered teeth at the bottom of the cutter head, thereby effectively flushing away the chips generated by the milling operation, effectively avoiding the milling chips from getting stuck between the surface of the milling cutter and the workpiece, preventing scratches from being generated on the surface of the workpiece due to the chips, and ensuring the processing quality of the milling operation on the workpiece.

[0014] 2. When installing the tungsten carbide milling cutter with staggered teeth, the joint is locked on the milling machine equipment through the connecting block and in cooperation with the milling machine. Then, the retaining pin is fully pushed to the inside of the connecting rod. Next, the connecting rod is inserted into the inside of the keyway in the joint through the key surface. The spring pushes the retaining pin outward from the inside of the card slot to the inside of the bayonet, thereby quickly installing and fixing the tool head. At the same time, it is convenient to replace the tool head. The width of the retaining pin located in the card slot is greater than the width of the retaining pin located in the bayonet. The spring has a large elastic force on the retaining pin. At the same time, during operation, the centrifugal force effectively prevents the retaining pin from moving from the inside of the bayonet to the inside of the card slot, thereby effectively ensuring the firmness of the installation of the tool head and preventing the tool head from falling off due to vibration or external force, ensuring the working safety of the tool head.
