Description

Technical Field

[0001] This utility model relates to the field of milling cutter equipment technology, specifically a straight-bar coated milling cutter that is easy to lock. Background Technology

[0002] Used for machining planes on horizontal milling machines. The cutting teeth are distributed around the circumference of the milling cutter, and are classified into straight teeth and helical teeth according to tooth shape. They are also classified into coarse teeth and fine teeth according to the number of teeth. Helical coarse-tooth milling cutters have fewer teeth, higher tooth strength, and larger chip space, making them suitable for roughing. Fine-tooth milling cutters are suitable for finishing. Milling cutters used in machining centers mostly adopt a spring-loaded clamping method, operating in a cantilevered state. During milling, sometimes the milling cutter may gradually extend from the clamp, eventually falling completely out and rendering the workpiece unusable. This is generally due to an oil film between the inner hole of the clamp and the outer diameter of the milling cutter shank, resulting in insufficient clamping force. Milling cutters are usually coated with anti-rust oil at the factory. If non-water-soluble cutting oil is used during cutting, a misty oil film will also adhere to the inner hole of the clamp. When oil films exist on both the shank and the clamp, the clamp is difficult to firmly clamp the shank, causing the milling cutter to loosen during machining.

[0003] A publicly available patent (publication number CN219616783U) discloses a straight-bar coated milling cutter that is easy to lock, including a cutter shank and a cutter head. The cutter head is mounted on the upper end of the cutter shank, and three circumferentially distributed slots are formed on the lower outer surface of the cutter head. Three circumferentially distributed buckles are hinged to the upper outer surface of the cutter shank. A cavity is formed inside the upper end of the cutter shank, and an internal hexagonal screw is threaded to the center of the cutter shank. A guide plate is slidably connected inside the cavity, and three circumferentially distributed guide frames are fixed to the bottom of the guide plate. A pin is slidably connected inside the guide frames, and three circumferentially distributed positioning pins are fixed to the bottom of the cutter head. This invention solves the problem in the above-mentioned solution where the milling cutter is only fixed by a clamping and limiting ring. Because the milling cutter needs to rotate during the machining process, loosening occurs between the cutter head and the bottom post, thus affecting the machining accuracy.

[0004] However, there are some problems in the use of existing straight-bar coated end mills: 1. Currently available straight-bar coated end mills lack a proper clamping mechanism when connecting to external components, making it difficult to embed and connect quickly. Furthermore, the clamping methods available are complex, increasing installation time for users. 2. Currently available straight-bar coated end mills lack a quick-connect locking mechanism, reducing overall locking efficiency and resulting in lower guidance and accuracy, making them prone to detachment after locking. Utility Model Content

[0005] The purpose of this invention is to provide a straight-bar coated end mill that is easy to lock, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a straight rod coated milling cutter that is easy to lock, comprising a rod body, a mounting and fixing assembly disposed at the bottom of the rod body, and a locking and clamping assembly disposed at the bottom of the rod body;

[0007] The mounting and fixing assembly includes a clamping seat disposed at the bottom of the rod body. The clamping seat is detachably connected to a housing at both ends. The housing has an inner cavity, and the clamping seat has a mounting hole inside, through which the rod body is connected.

[0008] The locking and clamping assembly includes a motor disposed inside the inner cavity. The output end of the motor is connected to the input end of a rotating shaft. An adjusting block is detachably connected to the surface of the rotating shaft. One end of the adjusting block is detachably connected to a connector, through which the rod is locked.

[0009] As a further embodiment of this utility model: a cutting head is connected to one end of the rod surface, a base is connected to the bottom of the rod, connecting plates are fixedly connected to both ends of the housing, and one end of the connecting plate is connected to the surface of the clamping seat.

[0010] As a further improvement of this utility model, the mounting and fixing assembly also includes a connecting hole formed on the surface of the base, and the base fits into the mounting hole.

[0011] As a further improvement of this utility model, the locking and clamping assembly also includes a fixed seat detachably connected to one side of the inner cavity, and a telescopic rod is detachably connected to the surface of the fixed seat.

[0012] As a further improvement of this utility model: one end of the telescopic rod is detachably connected to a connecting block, and a motor is connected to the surface of the connecting block.

[0013] As a further embodiment of this utility model: one end of the connector is movably connected to the inside of the connector hole, and the connector is movably connected to the inside of the mounting hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the initial connection of this utility model, the rod body is connected to the mounting hole on the surface of the clamping seat through the bottom mating base. The shape of the mounting hole matches the shape of the base, making it easy to insert and fix. The housing is connected through both ends of the clamping seat surface. The installation position is increased through the internal cavity opened inside the housing. The clamping seat has an internal cavity that communicates with the inside of the housing. The connection hole opened on the base surface increases the connection point between the milling cutter and the outside, which facilitates the installation and connection with the outside. Then, when the straight rod coated milling cutter is connected to the outside, it has a clamping mechanism that can hold it well, making it easy to embed and connect quickly. Unlike the more complicated clamping measures on the market, this method reduces the installation time of the user.

[0016] When locking is required, the rod body is installed in the connecting hole inside the clamping seat via the base. An external power source connects the telescopic rod's power output terminal, causing the telescopic rod to extend and retract, which in turn moves a connecting block detachably connected to its surface. This small motor is easy to control. Simultaneously, the motor is also connected to its power output terminal via an external power source, causing a rotating shaft connected to its output terminal to rotate. This shaft then rotates a connector at one end, which has threads to facilitate connection with the connecting hole on the base surface, allowing for quick fixing of the rod body. This design provides a quick-connect locking mechanism for the straight rod coated milling cutter, improving overall locking efficiency and providing high guidance and accuracy, preventing the rod from falling off after locking.

[0024] In addition to all the technical features in Embodiment 1, this embodiment also includes: a cutter head 2 is connected to one end of the surface of the rod body 1, a base 3 is connected to the bottom of the rod body 1, and the mounting and fixing assembly also includes a connecting hole 401 on the surface of the base 3. The base 3 fits inside the mounting hole 403. The cutter head 2 connected to the surface of the rod body 1 forms an integral milling cutter structure with the rod body 1. The base 3 increases the connectivity between the rod body 1 and the outside. At the same time, the connecting hole 401 facilitates connection with the connector 607. Threads are provided inside the connecting hole 401 and on the surface of the connector 607 to increase the connectivity between them.

[0025] Furthermore, the locking and clamping assembly also includes a fixed base 601 detachably connected to one side of the inner cavity 405. A telescopic rod 602 is detachably connected to the surface of the fixed base 601. A connecting block 603 is detachably connected to one end of the telescopic rod 602. A motor 604 is connected to the surface of the connecting block 603. The motor 604 is moved by the telescopic rod 602. The connecting block 603 facilitates the connection and disconnection between the motor 604 and the telescopic rod 602. The inner cavity 405 facilitates the movement of the telescopic rod 602, increasing the space for connection and movement.

[0026] Furthermore, one end of the connector 607 is movably connected to the inside of the connecting hole 401, and the connector 607 is movably connected to the inside of the mounting hole 403. The two ends of the housing 404 are fixedly connected to the connecting plates 5. One end of the connecting plate 5 is fitted to the surface of the clamping seat 402. The connecting plate 5 facilitates the installation of the housing 404 and increases the replaceability and maintainability of the internal motor 604 and telescopic rod 602. The connector 607 locks the base 3 and the clamping seat 402 together.

[0027] Working principle: The rod 1 is connected to the mounting hole 403 on the surface of the clamping seat 402 via the base 3 connected at the bottom. The shape of the mounting hole 403 matches the shape of the base 3, making it easy to insert and fix. The two ends of the clamping seat 402 are connected to the housing 404. The connecting plate 5 facilitates the installation of the housing 404 and increases the replaceability and maintainability of the internal motor 604 and telescopic rod 602. The connecting head 607 locks the base 3 and the clamping seat 402 together. The internal cavity 405 of the housing 404 increases the installation position. The inside of the clamping seat 402 is... An inner cavity 405 is provided, communicating with the interior of the housing 404. A connection hole 401 on the surface of the base 3 increases the connection point between the end mill and the external environment, facilitating installation and connection. Furthermore, the straight-bar coated end mill has a clamping mechanism that provides excellent gripping during connection, making it easy to embed and connect quickly. Unlike the more complex clamping methods on the market, this method reduces installation time for users. After the bar 1 is installed in the connection hole 401 inside the clamping seat 402 via the base 3, it is connected to an external power source. The telescopic rod 602 has a power output terminal. When the telescopic rod 602 operates, it drives a connecting block 603 connected to one end to extend and retract. The connecting block 603, in turn, drives a motor 604 detachably connected to its surface. The motor 604 is a small motor for easy operation. Simultaneously, the motor 604 is connected to an external power source for its power output terminal. The operation of the motor 604 drives a rotating shaft 605 connected to its output terminal to rotate. The rotating shaft 605 drives a connector 607 at one end to rotate. A cutter head 2, connected to the surface of the rod body 1, forms an integral milling cutter structure with the rod body 1. The base 3 increases the connectivity between the rod 1 and the outside, and the connecting hole 401 facilitates connection with the connector 607. Both the inside of the connecting hole 401 and the surface of the connector 607 are threaded to increase the connectivity between them. The threaded surface of the connector 607 makes it easy for the connector 607 to connect with the connecting hole 401 on the surface of the base 3, so as to quickly fix the rod 1. Then, the straight rod coated milling cutter has a measure to quickly connect and lock it when locking, which improves the overall locking efficiency, and has high guidance and accuracy, and is not easy to cause the problem of falling off after locking.
