Description

Technical Field

[0001] This utility model relates to a milling cutter for automotive machining, specifically a deep and shallow groove milling cutter for automotive machining, belonging to the field of automotive machining tool technology. Background Technology

[0002] Automotive processing is a type of machining, which refers to the process of changing the shape, size, or properties of a workpiece using mechanical equipment. Based on the difference in processing methods, it can be divided into cutting processing and pressure processing. When performing cutting processing such as grooving, a grooving cutter is required to create the grooves.

[0003] In the prior art, such as the grooving cutter disclosed in CN215392710U, since the grooving cutter is provided with two cutter bodies and several inserts are provided along the circumference of the cutter bodies, the grooving cutter can process the axial groove of the inner wall of the hole in one go when grooving the inner wall of the hole, and can also ensure that two grooves are processed at the same time. Therefore, the grooving cutter can improve the processing efficiency and shorten the production cycle when grooving the inner wall of the hole.

[0004] However, in implementing the relevant technology, the grooving cutter of the above design has the following problems: In the prior art, the cooperation of two cutter bodies and other components can improve the processing efficiency, but in actual use, the thickness and length of the processed object are not consistent, and a single cutter cannot adjust the depth of the groove, resulting in poor applicability. In view of this, a deep and shallow groove cutter for automotive processing is provided to overcome the above defects. Utility Model Content

[0005] This utility model addresses the problem that, in practical use, the thickness and length of the processed objects are inconsistent, and a single milling cutter cannot adjust the depth of the groove, resulting in poor applicability. It provides a deep and shallow groove milling cutter for automotive machining.

[0006] The present invention achieves the above objectives through the following technical solution: a deep and shallow groove milling cutter for automotive processing, comprising a connecting rod, a cutter bar extending through the interior of the connecting rod, and a cutter head fixed at the bottom end of the cutter bar, and an adjustment mechanism provided on the outer wall of the connecting rod;

[0007] The adjusting mechanism includes a slide groove, which is formed on the outer wall of the connecting rod, and a slider extends through the inside of the slide groove. A collar is slidably connected to one side of the slide groove on the outer wall of the connecting rod, and a connecting ring is slidably connected to the lower part of the outer wall of the connecting rod. A limit groove is formed at the top of the connecting ring, and a connecting block is slidably connected inside the limit groove. An abutment ring is fixed to one end of the connecting block that extends through the limit groove, and a positioning rod is fixed to the top of the abutment ring.

[0008] As a further improvement of this utility model: the tool holder forms an engaging structure between the slider and the groove, and the slider and the groove form a sliding structure.

[0009] As a further improvement of this utility model: the collar is threadedly connected to the connecting rod, and the connecting rod is threadedly connected to the connecting collar.

[0010] As a further improvement of this utility model: a mounting groove is provided on the outer wall of one end of the tool bar that penetrates into the connecting rod, and a support mechanism is provided inside the mounting groove.

[0011] As a further embodiment of this utility model: the support mechanism includes a sleeve rod, which is rotatably connected inside the mounting groove, and a rotating rod protrudes from the bottom end of the sleeve rod, and a through rod protrudes from the top end of the sleeve rod, with a connecting rod inserted into the end of the through rod away from the sleeve rod.

[0012] As a further embodiment of this utility model: the support mechanism further includes a universal ball seat, which is fixed to the end of the connecting rod away from the through rod, and a fixing rod is fixed to the top of the universal ball seat, and a connecting sleeve is sleeved on the outside of the fixing rod.

[0013] As a further embodiment of this utility model: the through rod and the rotating rod form a sliding structure, and the rotating rod forms a rotating structure with the placement groove through the rotating rod.

[0014] The beneficial effects of this utility model are as follows: The tool bar slides along the groove inside the connecting rod via a slider, and its applicability is improved by adjusting the depth of the groove. Subsequently, the position is adjusted by the collar and connecting ring threaded to the connecting rod, and the abutment ring slides through the connecting block and the limiting groove. This allows the abutment ring to drive the positioning rod to insert into the slider for positioning, and the connecting ring and abutment ring work together to clamp and position the slider, thereby clamping the tool bar to prevent loosening. After the tool bar passes through the connecting rod, the sleeve rod passes through the mounting groove via the rotating rod. The universal ball seat fixed to the connecting rod allows the fixing rod to rotate flexibly. Thus, the fixing rod and the connecting sleeve are threaded together, and the connecting sleeve is screwed into the reserved hole of the connecting rod. Together with the sleeve rod, the protruding rod, and the connecting rod, a telescopic rod is formed, which automatically adjusts according to the length of the groove, thereby keeping the tool bar in a stable state and preventing loosening during rotation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1 to 5As shown, a deep and shallow groove milling cutter for automotive machining includes a connecting rod 1, a cutter shank 2 extending through the inside of the connecting rod 1, a cutter head 3 fixed at the bottom end of the cutter shank 2, and an adjusting mechanism 4 provided on the outer wall of the connecting rod 1. The adjusting mechanism 4 includes a slide groove 401 formed on the outer wall of the connecting rod 1, a slider 402 extending through the inside of the slide groove 401, a collar 403 slidably connected to one side of the slide groove 401 on the outer wall of the connecting rod 1, a connecting ring 404 slidably connected to the lower part of the outer wall of the connecting rod 1, a limiting groove 405 formed at the top of the connecting ring 404, a connecting block 406 slidably connected inside the limiting groove 405, an abutment ring 407 fixed at one end of the connecting block 406 extending out of the limiting groove 405, and a positioning rod 408 fixed at the top of the abutment ring 407. The rod 2 forms an engaging structure between the slider 402 and the slide groove 401, and a sliding structure between the slider 402 and the slide groove 401. The collar 403 is threadedly connected to the connecting rod 1, and the connecting rod 1 is threadedly connected to the connecting ring 404. The tool bar 2 slides inside the connecting rod 1 along the slide groove 401 via the slider 402. The depth of the groove is adjusted to improve applicability. Then, the position is adjusted by the collar 403 and the connecting ring 404 threaded to the connecting rod 1, and the abutment ring 407 slides through the connecting block 406 and the limiting groove 405. This allows the abutment ring 407 to drive the positioning rod 408 to insert into the slider 402 for positioning. The abutment ring 407, together with the connecting ring 404 and the abutment ring 407, clamps and positions the slider 402, thereby clamping the tool bar 2 to prevent it from loosening. Example 2

[0023] In addition to all the technical features in Embodiment 1, this embodiment also includes: a mounting groove 5 is provided on the outer wall of one end of the tool holder 2 that penetrates into the connecting rod 1; a support mechanism 6 is provided inside the mounting groove 5; the support mechanism 6 includes a sleeve rod 601, which is rotatably connected to the inside of the mounting groove 5; a rotating rod 602 extends from the bottom end of the sleeve rod 601; a through rod 603 extends from the top end of the sleeve rod 601; a connecting rod 604 is inserted into the end of the through rod 603 away from the sleeve rod 601; the support mechanism 6 also includes a universal ball seat 605, which is fixed to the end of the connecting rod 604 away from the through rod 603; a fixing rod 606 is fixed to the top end of the universal ball seat 605; and the fixing rod 606... The outer sleeve is fitted with a connecting sleeve 607. The through rod 603 and the rotating rod 602 form a sliding structure. The rotating rod 602 and the mounting groove 5 form a rotating structure. After the cutter bar 2 passes through the connecting rod 1, the sleeve rod 601 passes through the mounting groove 5 via the rotating rod 602. The universal ball seat 605 fixed by the connecting rod 604 facilitates the flexible rotation of the fixed rod 606. The fixed rod 606 and the connecting sleeve 607 are threadedly connected. The connecting sleeve 607 is screwed into the reserved hole of the connecting rod 1. Together with the sleeve rod 601, the through rod 603 and the connecting rod 604, they form a telescopic rod. The telescopic rod is automatically adjusted according to the length of the groove, so as to keep the cutter bar 2 in a stable state and prevent it from loosening during rotation.

[0024] Working principle: Connecting rod 1 is used to connect with the clamping end of machine tools and other equipment. Tool bar 2 extends through connecting rod 1 and slots the object through tool head 3. When the length needs to be adjusted, the slider 402 slides along the slide groove 401 to adjust the extension length of tool bar 2. Then, the positioning rod 408 of the abutment ring 407 is inserted into the slider 402. With the cooperation of connecting block 406 and limiting groove 405, when the abutment ring 407 is not rotating, the connecting ring 404 threaded to tool bar 2 rotates and cooperates with the collar 403 threaded to tool bar 2 to adjust the position and press down the slider 402, thereby clamping and positioning the slider 402, facilitating the operation of the machine tool. The position of the cutter bar 2 is adjusted according to the depth of the groove. The slide groove 401 limits the slider 402 to prevent the cutter bar 2 from rotating. The sleeve rod 601 passes through the mounting groove 5 via the rotating rod 602. The rotating rod 602, the through rod 603, and the connecting rod 604 form a telescopic rod. The connecting sleeve 607, which is threaded to the fixing rod 606 fixed by the universal ball seat 605, is adjusted. The sleeve passes through the corresponding reserved hole at the bottom of the connecting rod 1 for limiting. At the same time, the telescopic rod formed by the rotating rod 602, the through rod 603, and the connecting rod 604 extends and retracts with the adjusted position, thereby limiting the cutter bar 2 and preventing it from becoming loose.
