Description

Technical Field

[0001] The invention relates to the technical field of milling cutters, in particular to a milling cutter with high stability. Background Art

[0002] A milling cutter is a rotary tool with one or more teeth used for milling. During operation, each tooth cuts off the excess of the workpiece in turn and intermittently. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. The internal structure of the existing milling cutter fixing device is relatively simple, and the installation or disassembly operation steps are relatively cumbersome. It is necessary to manually twist the fixing parts in turn to fix them, and workers who work for a long time are prone to forget or under-tighten one place, so that the milling cutter is extremely unstable and easy to shake during operation. In view of this, we propose a milling cutter with high stability. Summary of the invention

[0003] The object of the present invention is to provide a milling cutter with high stability to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A high-stability milling cutter, a high-stability milling cutter, comprises a cutter body, a stabilizing block is fixedly mounted on the surface of the cutter body, a limiting device is slidably connected to the top of the stabilizing block, a support and a driving device are respectively arranged on the surface of the stabilizing block, and a positioning groove is opened on the upper surface of the stabilizing block.

[0006] Preferably, a support block is welded and fixedly connected inside the stabilizing block, a rotating rod is rotatably connected to the surface of the support block, an oblique thread body is fixedly connected to the surface of the rotating rod, and a bevel gear is fixedly connected to the top end of the rotating rod.

[0007] Preferably, the driving device comprises a tooth body, the upper surface of the tooth body meshes with the surface of the bevel gear, the bottom of the tooth body is fixedly connected to a fixed block, and the bottom of the fixed block is fixedly connected to a rotating block.

[0008] Preferably, a sliding wheel is fixedly installed on the bottom of the fixed block, and a cross plate is slidably connected to the bottom of the sliding wheel. The surface of the cross plate is welded and fixed to the inner wall of the support member, and a sliding groove is opened on the surface of the cross plate.

[0009] Preferably, a torsion spring is fixedly connected to the surface of the rotating block, and a lower end of the torsion spring is fixedly connected to the bottom wall inside the supporting member.

[0010] Preferably, the limiting device comprises a brake block, a surface of which is provided with a moving groove, and a bottom of the brake block has bevel teeth.

[0011] Preferably, the number of the brake blocks is three, and the three brake blocks are distributed in a ring shape with the center of the stabilizing block as the axis of symmetry.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The high-stability milling cutter is used in cooperation with the internal structure of the limiting device and the driving device. When the worker rotates the driving device, the driving device will move the limiting device through the internal structure, which can facilitate the worker to quickly replace or install different milling cutters, effectively reduce the operation steps for the worker to install or replace the milling cutter, effectively reduce the effect of the worker leaving a place without fixing, and effectively improve the effect of fixing the milling cutter, thereby greatly improving the stability of the milling cutter when in use and reducing the effect of shaking of the milling cutter when in use.

[0014] 2. This high-stability milling cutter is used in conjunction with a torsion spring and a sliding wheel. When the worker rotates the driving device, the driving device will drive the torsion spring to rotate, thereby causing the internal force of the driving device to be applied. When the worker relaxes the driving device, the driving device will quickly return to its original position through the torsion spring and the sliding wheel, making it convenient for the worker to operate and use.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0026] See also Figure 1-Figure 7 As shown, a technical solution provided by the present invention is:

[0027] A high-stability milling cutter comprises a cutter body 1, a stabilizing block 2 is fixedly mounted on the surface of the cutter body 1, a limiting device 3 is slidably connected to the top of the stabilizing block 2, a supporting member 4 and a driving device 5 are respectively arranged on the surface of the stabilizing block 2, and a positioning groove 14 is opened on the upper surface of the stabilizing block 2.

[0028] In this embodiment, the interior of the stabilizing block 2 is welded and fixedly connected to a support block 6, the surface of the support block 6 is rotatably connected to a rotating rod 7, the surface of the rotating rod 7 is fixedly connected to an oblique threaded body 9, and the top of the rotating rod 7 is fixedly connected to a bevel gear 8, which can better control the movement of the limiting device 3.

[0029] Furthermore, the driving device 5 includes a tooth body 51, the upper surface of the tooth body 51 is meshed with the surface of the bevel gear 8, the bottom of the tooth body 51 is fixedly connected with a fixed block 52, and the bottom of the fixed block 52 is fixedly connected with a rotating block 53. Since the tooth body 51 is meshed with the bevel gear 8, it is convenient for the staff to adjust the position of the limiting device 3.

[0030] Furthermore, a sliding wheel 10 is fixedly installed at the bottom of the fixed block 52, and a horizontal plate 11 is slidably connected to the bottom of the sliding wheel 10. The surface of the horizontal plate 11 is welded and fixed to the inner wall of the support member 4, and a sliding groove 13 is opened on the surface of the horizontal plate 11, which effectively reduces the friction between the sliding wheel 10 and the horizontal plate 11 and effectively improves the rotation effect of the driving device 5.

[0031] In addition, the surface of the rotating block 53 is fixedly connected to a torsion spring 12, and the lower end of the torsion spring 12 is fixedly connected to the bottom wall inside the support member 4. When the staff rotates the driving device 5, the driving device 5 will drive the torsion spring 12 to rotate, so that the internal force of the driving device 5 can be applied. When the staff relaxes the driving device 5, the driving device 5 will quickly restore to its original position through the torsion spring 12 and the sliding wheel 10, which is convenient for the staff to operate and use.

[0032] It is worth mentioning that when the staff rotates the driving device 5, the driving device 5 will move the limiting device 3 through the internal structure, which can facilitate the staff to quickly replace or install different milling cutters, effectively reduce the operating steps for the staff to install or replace the milling cutter, effectively reduce the effect of the staff leaving a place without fixing, and effectively improve the effect of fixing the milling cutter, thereby greatly improving the stability of the milling cutter during use and reducing the shaking effect of the milling cutter during use.

[0033] In addition, the limiting device 3 includes a brake block 31, a moving groove 32 is opened on the surface of the brake block 31, and the bottom of the brake block 31 is provided with bevel teeth 33. Since the bottom of the brake block 31 is provided with bevel teeth 33, the effect of the movement of the brake block 31 can be better limited, thereby effectively reducing the effect of the movement of the brake block 31 during operation.

[0034] Furthermore, there are three brake blocks 31, and the three brake blocks 31 are distributed in a ring shape with the center of the stabilizing block 2 as the axis of symmetry, which can better fix the milling cutter and effectively improve the stability of the milling cutter.

[0035] When the high-stability milling cutter of the present invention is in use, the staff rotates the driving device 5 according to the actual usage situation, and the driving device 5 can simultaneously drive the torsion spring 12 and the tooth body 51 to rotate, the tooth body 51 can drive the bevel gear 8 to rotate, the bevel gear 8 can rotate the rotating rod 7, the rotating rod 7 can drive the oblique thread body 9 to rotate, and the oblique thread body 9 can move the limiting device 3, which can facilitate the staff to replace and use different milling cutters. The staff then rotates the surface of the driving device 5 under force, and the driving device 5 will be subjected to the torsion force of the torsion spring 12 and quickly return to its original position. The limiting device 3 can better fix the milling cutter, effectively reducing the shaking effect of the milling cutter during operation.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
