Description

Technical Field

[0001] The present application relates to the technical field of annular groove milling cutters, and more particularly to an adjustable annular groove milling cutter. Background Art

[0002] A milling cutter is a rotary cutter with one or more cutting teeth used for milling. During operation, each cutting tooth contacts the workpiece in turn and cuts off the surplus of the workpiece. An annular groove milling cutter is a milling cutter used for cutting an annular groove.

[0003] Our company currently has an annular groove milling cutter, as Figure 1 shown, which includes a cutter body 90, two tool mounting seats 91 and two blades 92. The two tool mounting seats 91 are arranged centrosymmetrically and are fixedly connected to the cutter body 90 by welding. Each tool mounting seat 91 has a mounting groove 911, and a blade 92 is detachably mounted in each mounting groove 911. The annular groove milling cutter has relatively high structural strength. However, since the position of the tool mounting seat 91 on the cutter body 90 is fixed, and each tool mounting seat 91 has only one mounting groove 911, the distance between the blade 92 mounted in one mounting groove 911 and the other blade 92 is constant.

[0026] Application Overview

[0027] In the existing annular groove milling cutter, since the position of the tool mounting seat on the tool body is fixed, and there is only one mounting groove on each of the tool mounting seats, the distance between the cutting blades mounted on one mounting groove and another cutting blade is constant. The annular groove milling cutter can only machine annular grooves with one radial dimension, and its versatility is poor.

[0028] Based on the above technical problems, the present application proposes an adjustable annular groove milling cutter. Among them, the adjustable annular groove milling cutter has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economy. At the same time, for manufacturers, the adjustable annular groove milling cutter provided by the present application is easy to produce and has low costs, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0029] Schematic adjustable annular groove milling cutter

[0030] Reference Figures 2 to 5 , according to an adjustable annular groove milling cutter of a preferred embodiment of the present utility model, it includes a tool body 10 and two tool mounting seats 20.

[0031] Specifically, as Figure 2 shown, the two tool mounting seats 20 are arranged in central symmetry. Each tool mounting seat 20 is slidably disposed at one end of the tool body 10 and is detachably connected to the tool body 10. A cutting blade 30 is detachably mounted on each tool mounting seat 20.

[0032] Further, to enable the tool mounting seat 20 to be slidably disposed on the tool body 10, as Figure 2 and Figure 3As shown, one end face of the tool body 10 has a plurality of convex teeth 101 arranged at intervals. Each convex tooth 101 is strip-shaped and parallel to each other, as Figure 2 and Figure 4 shown. One end of each tool mounting seat 20 has a plurality of through slots 201 at both ends. The convex teeth 101 correspond to the slots 201 one by one. When the tool mounting seat 20 is slidably arranged on the tool body 10, each convex tooth 101 extends into the corresponding slot 201.

[0033] It should be noted that when the convex tooth 101 extends into the corresponding slot 201, it provides a limit for the circumferential rotation of the mounting seat. When the blade 30 contacts the workpiece to be machined, the blade 30 rotates circumferentially around the central axis of the tool body 10. By engaging the slot 201 of the tool mounting seat 20 with the corresponding convex tooth 101, the tool mounting seat 20 is effectively prevented from rotating circumferentially relative to the tool body 10. At the same time, the tool mounting seat 20 can move left and right in the length direction of the slot 201 to adjust the distance between the blades 30 on the two tool mounting seats 20 to machine annular grooves with different radial dimensions. Obviously, compared with the prior art where the tool mounting seat 20 is fixedly connected to the tool body 10 and each tool mounting seat 20 only has a groove for mounting the blade 30, the embodiment of the present application has the advantages of being able to machine multi-size annular grooves and better versatility.

[0034] Furthermore, after the two tool mounting seats 20 slide to a predetermined position on the tool body 10, to fix the position of the tool mounting seat 20 and at the same time achieve the detachable connection between the tool mounting seat 20 and the tool body 10, as Figure 3 shown, the end of the tool body 10 with the convex teeth 101 also has a plurality of first threaded holes 102, as Figure 4 shown. Both sides of each tool mounting seat 20 have a waist-shaped slot 202, and each waist-shaped slot 202 faces at least one of the first threaded holes 102, as Figure 2 shown. The adjustable annular groove milling cutter further includes a plurality of first fasteners 40. The first fasteners 40 correspond to the first threaded holes 102 one by one. Each first fastener 40 passes through the corresponding waist-shaped slot 202 and is threadedly connected to the corresponding first threaded hole 102.

[0035] It should be noted that the first fastener 40 is implemented as a bolt with a nut. By setting the first threaded hole 102 on the tool body 10, the position of the first fastener 40 in the length direction of the convex tooth 101 is constant, and the tool mounting seat 20 is slidably mounted on the tool body 10. Therefore, the waist groove 202 is set on the tool mounting seat 20, and the first fastener 40 is passed through the waist groove 202 to avoid interference between the tool mounting seat 20 and the first fastener 40 during the sliding process.

[0036] It should also be noted that the waist-shaped groove 202 is a stepped groove in the groove depth direction. Assuming that the first fastener 40 is screwed into the first threaded hole 102 at this time, and the nut part of the first fastener 40 does not abut against the tool mounting seat 20, the processing personnel can slide the tool mounting seat 20 at will. At this time, the tool mounting seat 20 slides along the convex teeth 101 and also slides along the first fastener 40; when the tool mounting seat 20 slides to the specified position, the processing personnel only needs to tighten the first fastener 40 and make the nut part of the fastener abut against the step of the waist-shaped groove 202 to achieve the fixed installation of the tool mounting seat 20 on the tool body 10.

[0037] Furthermore, in order to realize that the blade 30 is fixedly mounted on the tool mounting seat 20, as shown in FIG. Figure 2 and Figure 4 As shown, each of the tool mounting seats 20 has a support portion 203 and a blade mounting slot 204 with a notch, the support portion 203 is located at one end of the blade mounting slot 204 away from the notch, and each of the blade mounting slots 204 is provided with a blade 30, and the blade 30 is threadedly connected to the support portion 203.

[0038] It should be noted that the blade 30 is further implemented as a diamond-shaped blade, the blade mounting groove 204 is a V-shaped groove, and a cross-section of the abutting portion 203 is triangular.

[0039] Furthermore, in order to ensure that the two tool mounting seats 20 are still centrally symmetrically arranged after sliding, as Figures 2 to 4 As shown, each of the tool mounting seats 20 has a first groove 205 on both sides, and the tool body 10 has a plurality of second grooves 103 arranged in an array on both sides of one end of the convex tooth 101, and the spacing between two adjacent second grooves 103 is equal.

[0040] It should be noted that, assuming that in the initial state, the first groove 205 of each of the tool mounting seats 20 is aligned with the corresponding second groove 103, after sliding one of the tool mounting seats 20 several intervals in opposite or opposite directions and aligning it with another second groove 103, the processing personnel also aligns the other tool mounting seat 20 with the corresponding second groove 103 in opposite or opposite directions to ensure that the distances between the two tool mounting seats 20 and the tool body 10 are equal and maintain a centrally symmetrical arrangement.

[0041] Furthermore, in order to enable the processing personnel to quickly slide the two tool mounting seats 20 to a common spacing, such as Figure 3 As shown, one end of the tool body 10 having the protruding tooth 101 also has a positioning hole 104 . The positioning hole 104 is located between the two tool mounting seats 20 , and the central axis of the positioning hole 104 coincides with the central axis of the tool body 10 .

[0042] It should be noted that before sliding, the processing personnel inserts an insertion rod into the positioning hole 104, and the rod diameter of the insert is equal to the commonly used spacing. At this time, the processing personnel only needs to move the two tool mounting seats 20 toward the direction of the insertion rod and make the two tool mounting seats 20 abut against the insertion rod to quickly obtain the specified position.

[0043] Further, in order to facilitate the connection of the cutter body 10 with the spindle of the milling machine, as Figure 5 As shown, the end of the blade body 10 away from the protruding tooth 101 has a countersunk hole 105 and a side through hole 106, the countersunk hole 105 extends from the end surface of the blade body 10 away from the protruding tooth 101 to the other end, and the side through hole 106 passes through the side of the blade body 10 and is connected to the countersunk hole 105.

[0044] In summary, the adjustable annular groove milling cutter based on the embodiment of the present application is explained, which provides the adjustable annular groove milling cutter with advantages such as the ability to process annular grooves of various sizes and better versatility.

[0045] It is worth mentioning that in the embodiment of the present application, the adjustable annular groove milling cutter has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the adjustable annular groove milling cutter provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0046] Those skilled in the art should understand that the embodiments of the present utility model described above and shown in the accompanying drawings are only examples and do not limit the present utility model. The object of the present utility model has been fully and effectively achieved. The functions and structural principles of the present utility model have been demonstrated and explained in the embodiments, and without departing from this principle, any deformation or modification can be made to the embodiments of the present utility model.
