Description

Technical Field

[0001] This utility model relates to the field of mechanical clamping equipment technology, and in particular to a milling machine insert clamping mechanism that is easy to adjust the angle. Background Technology

[0002] Clamping mechanisms are devices used in mechanical manufacturing to fix the workpiece in the correct position for processing or inspection. In the mechanical manufacturing industry, when machining cutting tools, the cutting tool needs to be fixedly installed on a fixed base before processing. Existing clamping mechanisms for milling machine cutting tools often only have a fixing function. When it is necessary to focus on grinding a certain part of the cutting tool, it becomes very inconvenient when the tool needs to be rotated and adjusted.

[0003] In the prior art, patent (CN217433846U) proposes a clamping mechanism for milling machine insert machining, including a machine body, a fixed base, and a rotating assembly. The rotating assembly includes a rotating column, a shaft, a rotating handle, a rotating bushing, and a connecting block. The rotating column is rotatably connected to the machine body, the rotating bushing is fixedly connected to the rotating column, the shaft is rotatably connected to the rotating bushing, the rotating handle is fixedly connected to the shaft, the connecting block is fixedly connected to the shaft, and the fixed base is fixedly connected to the connecting block. Rotating the rotating column can adjust the horizontal position angle of the insert. Rotating the rotating handle causes the shaft to rotate, which in turn causes the connecting block to rotate, thereby causing the fixed base to rotate and thus changing the angle of the fixed insert. This makes it very convenient when the tool needs to be rotated and adjusted.

[0004] However, in the aforementioned prior art, after the connecting block rotates, the shaft stability is poor, and it is easy for it to continue to deflect, affecting the steering. Utility Model Content

[0005] The purpose of this invention is to provide a milling machine insert clamping mechanism that is easy to adjust the angle, which solves the problem in the prior art that the shaft has poor stability after the connecting block rotates, and is prone to continued deflection, affecting the direction of rotation.

[0006] To achieve the above objectives, this utility model provides a milling machine insert clamping mechanism with easily adjustable angle, comprising a machine body and an adjustment mechanism. The adjustment mechanism includes a mounting ring, a rotating column, two limiting buckles, a steering assembly, a limiting assembly, a fixed base, and two clamping assemblies. Both clamping assemblies are rotatably connected to the fixed base and located inside the fixed base. The fixed base is fixedly connected to the steering assembly and located on one side of the steering assembly. The limiting assembly is fixedly connected to the steering assembly and located around the steering assembly. The steering assembly is fixedly connected to the rotating column and located at the lower end of the rotating column. The upper end of the rotating column is rotatably connected to the mounting ring and located below the mounting ring. The mounting ring is fixedly connected to the machine body and located below the machine body. Both limiting buckles are fixedly connected to the rotating column and located on both sides of the rotating column.

[0007] The steering assembly includes a bushing, a shaft, multiple teeth, and two abutment pads. The two abutment pads are fixedly connected to the bushing and are located on both sides of the bushing. Each tooth is fixedly connected to the bushing and is located inside the bushing. The shaft is rotatably connected to the bushing and is located inside the bushing. The bushing is fixedly connected to the rotating column and is located at the lower end of the rotating column.

[0008] The limiting component includes a limiting plate and a movable plate. The movable plate is slidably connected to the shaft and located on the periphery of the shaft. The limiting plate is fixedly connected to the shaft and located on the periphery of the shaft.

[0009] The fixed base includes a base body and a connecting block. The upper end of the connecting block is fixedly connected to the shaft and is located on one side of the shaft. The base body is fixedly connected to the connecting block and is located at the lower end of the connecting block.

[0010] Each of the clamping components includes an adjusting screw, a pad, and a protective pad. The protective pad is fixedly connected to the pad and located on one side of the pad. The other side of the pad is rotatably connected to the adjusting screw and located at one end of the adjusting screw. The adjusting screw is rotatably connected to the base and located inside the base.

[0011] This utility model discloses a milling machine insert clamping mechanism that facilitates angle adjustment. The inner side of the bushing in the steering assembly is provided with multiple protruding teeth, which can be adapted to the connecting block in the fixed seat. Therefore, after the shaft is rotated, the overall deflection angle of the equipment is limited by aligning the connecting block and the corresponding protruding teeth. This design is simple in structure, easy to manufacture, and solves the problem that the shaft has poor stability after the connecting block rotates, making it easy to continue to deflect and affect the steering.

[0022] This utility model provides a milling machine insert clamping mechanism with an easily adjustable angle, including a body 101 and an adjustment mechanism 102. The adjustment mechanism 102 includes a mounting ring 103, a rotating column 104, two limiting buckles 105, a steering assembly 106, a limiting assembly 107, a fixed seat 108, and two clamping assemblies 109. The steering assembly 106 includes a bushing 110, a shaft 111, multiple protruding teeth 112, and two abutment pads 113. The limiting assembly 107 includes a limiting plate 114 and a movable plate 115. The fixed seat 108 includes a seat body 116 and a connecting block 117. Each clamping assembly 109 includes an adjusting screw 118, a pad 119, and a protective pad 120.

[0023] In this specific embodiment, both clamping assemblies 109 are rotatably connected to the fixed base 108. The fixed base 108 is fixedly connected to the steering assembly 106. The limiting assembly 107 is fixedly connected to the steering assembly 106. The steering assembly 106 is fixedly connected to the rotating column 104. The upper end of the rotating column 104 is rotatably connected to the mounting ring 103. The mounting ring 103 is fixedly connected to the machine body 101. Both limiting buckles 105 are fixedly connected to the rotating column 104. Both supporting pads 113 are fixedly connected to the bushing 110. Each tooth 112 is fixedly connected to the bushing 110. The shaft 111 is rotatably connected to the bushing 110. The bushing 110 is fixedly connected to the rotating column 104. The movable disc 115 is slidably connected to the shaft 111. The limiting disc 114... The upper end of the connecting block 117 is fixedly connected to the shaft 111, the seat 116 is fixedly connected to the connecting block 117, the protective pad 120 is fixedly connected to the pad plate 119, the other side of the pad plate 119 is rotatably connected to the adjusting screw 118, and the adjusting screw 118 is rotatably connected to the seat 116. The inner side of the bushing 110 in the steering assembly 106 is provided with multiple protruding teeth 112, which can be adapted to the connecting block 117 in the fixed seat 108. Therefore, after rotating the shaft 111, the overall deflection angle of the device is limited by aligning the connecting block 117 and the corresponding protruding teeth 112. This design is simple, easy to manufacture, and solves the problem that the shaft 111 is unstable after the connecting block rotates, and is prone to deflection, affecting the steering.

[0024] Both clamping components 109 are located inside the fixed base 108, which is located on one side of the steering component 106. The limiting component 107 is located around the steering component 106, which is located at the lower end of the rotating column 104. The upper end of the rotating column 104 is located below the mounting ring 103, which is located below the body 101. Two limiting buckles 105 are located on both sides of the rotating column 104. On one side of the connecting block 117, there is a groove that matches each of the protruding teeth 112. After the operator rotates the shaft 111, he moves the shaft 111 again so that the groove in the shaft 111 fits into the corresponding protruding tooth 112, thus stabilizing the angle.

[0025] Secondly, the two supporting pads 113 are respectively located on both sides of the bushing 110, each of the protruding teeth 112 is located on the inner side of the bushing 110, the shaft 111 is located on the inner side of the bushing 110, the bushing 110 is located at the lower end of the rotating column 104, the movable disk 115 is located on the periphery of the shaft 111, and the limiting disk 114 is located on the periphery of the shaft 111. During the pulling and rotating of the shaft 111, the movable disk 115 rotates with the shaft 111. In conjunction with the limiting disk 114, it can protect the two ends of the shaft 111 from contacting the bushing 110. Lubricating oil is added to the inner side of the limiting disk 114 and the movable disk 115 to reduce the friction required to rotate the shaft 111, making it easier for the operator to rotate the shaft 111 and facilitate the operation.

[0026] Meanwhile, the upper end of the connecting block 117 is located on one side of the shaft 111, the seat 116 is located at the lower end of the connecting block 117, the protective pad 120 is located on one side of the pad 119, the other side of the pad 119 is located at one end of the adjusting screw 118, and the adjusting screw 118 is located inside the seat 116. When using this device, first rotate the two adjusting screws 118 to clamp the corresponding protective pad 120 and the pad 119 to the milling cutter. Then, pull the shaft 111 to move the side of the connecting block 117 near the tooth 112 away from the limiting plate 114. On one side, the connecting block 117 and the seat 116 can rotate with the rotation of the shaft 111. After the rotation is adjusted to the target angle, the shaft 111 is pulled again to engage the slot on the outside of the shaft 111 with the corresponding protruding teeth 112, thus completing the adjustment of the angle of the connecting block 117 and the seat 116. During this process, after the connecting block 117 rotates to a parallel position, the abutment pads 113 on both sides of the bushing 110 can also protect and support the connecting block 117, thus protecting the connecting block 117 and extending its service life.

[0027] In this embodiment, one side of the connecting block 117 has a groove that matches each of the protruding teeth 112. After the operator rotates the shaft 111, they can move the shaft 111 again to allow the groove in the shaft 111 to fit into the corresponding protruding tooth 112, thus stabilizing the angle. During the pulling and rotating of the shaft 111, the movable disk 115 rotates with the shaft 111. In conjunction with the limiting disk 114, it can protect the two ends of the shaft 111 from contacting the bushing 110. Lubricating oil is added to the inner sides of both the limiting disk 114 and the movable disk 115 to reduce the friction required to rotate the shaft 111, making it easier for the operator to rotate the shaft 111 and facilitating operation. When using this device, first rotate the two adjusting screws 118. Clamp the corresponding protective pads 120 and pads 119 onto the milling cutter, then pull the shaft 111, moving the side of the connecting block 117 closest to the protruding teeth 112 away from the limiting plate 114, so that the connecting block 117 and the seat 116 can rotate with the rotation of the shaft 111. After the rotation is adjusted to the target angle, pull the shaft 111 again, engaging the slot on the outside of the shaft 111 with the corresponding protruding teeth 112, thus completing the adjustment of the angle of the connecting block 117 and the seat 116. During this process, after the connecting block 117 rotates to a parallel position, the abutment pads 113 on both sides of the bushing 110 can also protect and support the connecting block 117, extending its service life.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
