Description

Technical Field

[0001] This utility model relates to a tapered shank vertical milling cutter, specifically a tapered shank vertical milling cutter with a coating, belonging to the field of milling cutter technology. Background Technology

[0002] Tapered shank end mills are the most commonly used type of end mill on CNC machine tools. End mills have cutting tools on both the cylindrical surface and the end face, which can perform cutting simultaneously or individually. They are mainly used for plane milling, groove milling, step milling, and profile milling. Due to their excellent cutting capabilities, tapered shank end mills are also widely used in the machining of various workpieces.

[0003] However, existing tapered shank end mills still have certain problems. For example, in the end mill with a composite coating disclosed in publication number CN109262041A, although it facilitates the replacement of damaged inserts and cutter heads and ensures the stability of the connecting rod during use, preventing the connecting rod from breaking and causing danger, most end mills currently need to move on the surface of the workpiece during face milling. When moving, they need to be linked with external transmission equipment, such as using the extension and retraction of a cylinder to drive the entire connecting structure of the end mill to move. However, since different workpieces have strict requirements for the distance the end mill moves during face milling, it needs to be adjusted according to the actual situation. The extension and retraction of the cylinder needs to be precisely controlled by electrical control equipment, which is relatively cumbersome. Moreover, due to the high cost of cylinders and electrical control equipment, the overall processing cost of the end mill is high, which can easily lead to unnecessary economic losses. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to overcome the aforementioned shortcomings in existing technologies by proposing a coated tapered shank vertical milling cutter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a coated tapered shank end mill, comprising a base, a support seat, a support frame, a support slider, a servo motor, a tapered shank end mill, an active mechanism, and a driven mechanism. The support seat is slidably connected to the base, the support frame is fixed to the base and partially located above the support seat, and a slot is provided at the top of the support frame. The support slider is slidably engaged in the slot at the top of the support frame, the servo motor is fixed to the support slider, and the tapered shank end mill is coaxially connected to the output shaft of the servo motor.

[0006] The active mechanism includes a rack, a gear, and a workpiece support tray. The rack is fixed to one side of the support base, the gear is rotatably connected to the base near the rack and meshes with the rack, the workpiece support tray is coaxially fixed to the top of the gear, and the tapered shank end mill is located above the workpiece support tray.

[0007] Preferably, the driven mechanism includes a limiting seat, a limiting slider, and a locking screw. One end of the limiting seat is rotatably connected to the support seat, and the other end is connected and locked to the support seat by the locking screw. The limiting seat is inclined and has a slot. The limiting slider is rotatably connected to the end of the support slider away from the tapered shank end mill and is slidably engaged in the slot of the limiting seat.

[0008] Preferably, the support is provided with an adjustment groove, the adjustment groove has an arc-shaped structure, and the locking screw on the limiting seat is slidably engaged in the adjustment groove.

[0009] Preferably, a linkage block is fixed at the bottom of the support, and a sliding groove is provided on the base. Both the linkage block and the sliding groove are trapezoidal in shape, and the linkage block is slidably engaged in the sliding groove.

[0010] Preferably, a screw hole is provided through the linkage block, and a lead screw is rotatably connected inside the base, with the lead screw threaded into the screw hole.

[0011] Preferably, the surface of the taper shank end mill is coated with a diamond coating.

[0012] The beneficial effects of this utility model are:

[0013] 1) By setting up an active mechanism and a driven mechanism, the support seat in the active mechanism can engage the gears through the rack when sliding, and drive the workpiece support tray to rotate, so that the workpiece on the workpiece support tray can rotate, thereby improving the cutting efficiency of the tapered shank end mill.

[0014] 2) When the support seat slides, the driven mechanism drives the limit slider to slide within the limit seat, which in turn drives the entire support slider to slide on the support frame. This allows the tapered shank end mill to move on the surface of the workpiece during face milling, avoiding the need for expensive external transmission equipment and effectively reducing processing costs. At the same time, the arc-shaped adjustment groove allows the tilt angle of the limit seat to be adjusted to a certain extent, thereby adjusting the overall displacement of the support slider and further increasing the applicability of the end mill.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, as Figures 1 to 4 As shown, a coated tapered shank end mill includes a base 1, a support 2, a support frame 3, a support slider 4, a servo motor 5, a tapered shank end mill 6, an active mechanism 7, and a driven mechanism 8. The support 2 is slidably connected to the base 1, the support frame 3 is fixed to the base 1 and partially located above the support 2, and a slot is provided on the top of the support frame 3. The support slider 4 is slidably engaged in the slot on the top of the support frame 3, the servo motor 5 is fixed to the support slider 4, and the tapered shank end mill 6 is coaxially connected to the output shaft of the servo motor 5.

[0022] The active mechanism 7 includes a rack 71, a gear 72 and a workpiece support tray 73. The rack 71 is fixed on one side of the support 2. The gear 72 is rotatably connected to the base 1 on the side near the rack 71 and meshes with the rack 71. The workpiece support tray 73 is coaxially fixed on the top of the gear 72, and the tapered shank end mill 6 is located above the workpiece support tray 73.

[0023] The driven mechanism 8 includes a limit seat 81, a limit slider 82, and a locking screw 84. One end of the limit seat 81 is rotatably connected to the support seat 2, and the other end is connected and locked to the support seat 2 by the locking screw 84. The limit seat 81 is inclined and has a slot. The limit slider 82 is rotatably connected to the end of the support slider 4 away from the tapered shank end mill 6 and slides into the slot of the limit seat 81.

[0024] The support 2 is provided with an adjustment groove 83, which has an arc-shaped structure, and the locking screw 84 on the limit seat 81 is slidably engaged in the adjustment groove 83.

[0025] In this invention, by setting an active mechanism 7 and a driven mechanism 8, the support seat 2 in the active mechanism 7 can, when sliding, engage the gear 72 through the rack 71, thereby driving the workpiece support tray 73 to rotate. This allows the workpiece on the workpiece support tray 73 to rotate, thus improving the cutting efficiency of the tapered shank end mill 6. Simultaneously, when the support seat 2 slides, the driven mechanism 8 drives the limiting slider 82 to slide within the limiting seat 81, thereby causing the entire support slider 4 to slide on the support frame 3. This allows the tapered shank end mill 6 to move on the surface of the workpiece during face milling, avoiding the need for expensive external transmission equipment and effectively reducing processing costs. Furthermore, the arc-shaped adjustment groove 83 allows for adjustment of the tilt angle of the limiting seat 81, thereby adjusting the overall displacement of the support slider 4 and further increasing the applicability of the end mill.

[0026] Example 2, as Figures 1 to 4 As shown, in addition to all the technical features in Embodiment 1, this embodiment also includes: a linkage block 75 fixed at the bottom of the support 2, and a sliding groove provided on the base 1. Both the linkage block 75 and the sliding groove are trapezoidal structures, and the linkage block 75 is slidably engaged in the sliding groove. The trapezoidal structure limits the linkage block 75 to prevent the support 2 from slipping.

[0027] A screw hole is provided through the linkage block 75, and a lead screw 74 is rotatably connected inside the base 1. The lead screw 74 is threaded in the screw hole. The rotation of the lead screw 74 causes the linkage block 75 to be threaded and linked, thereby allowing the support seat 2 to slide on the base 1.

[0028] The surface of the tapered shank end mill 6 is coated with a diamond coating, which increases the hardness of the tapered shank end mill 6 and thus improves its service life.

[0029] When using this tapered shank end mill, first fix the workpiece on the workpiece support tray 73, and then adjust the tilt angle of the limit seat 81 according to the actual processing requirements. During adjustment, rotate the limit seat 81, at which time the locking screw 84 slides in the adjustment groove 83. After adjusting the limit seat 81 to the appropriate tilt angle, lock the limit seat 81 with the locking screw 84. Then start the servo motor 5 to drive the tapered shank end mill 6 to rotate, and mill the workpiece through the tapered shank end mill 6. During the milling process, the lead screw 74 rotates and drives the linkage block 75 to be threaded, thereby causing the support seat 2 to slide on the base 1. When the support seat 2 slides, the rack 71 and the gear 72 mesh and drive the workpiece support tray 73 to rotate. At the same time, the limit slider 82 slides in the limit seat 81, thereby driving the support slider 4 to slide on the support frame 3, so that the tapered shank end mill 6 can be displaced on the workpiece.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
