Description

Technical Field

[0001] The utility model relates to the field of mold processing, in particular to a cutting tool head used for mold processing. Background Art

[0002] Cutting tools are tools used for cutting processing in mechanical manufacturing. Metal cutting processing is a process of using tools to remove excess material from the workpiece to obtain parts that meet the requirements in terms of shape, dimensional accuracy and surface quality. Cutting tools are usually installed on CNC lathes to cut metal materials. Cutting tools are prone to damage or aging under long-term and high-intensity working intensity. If the cutting tools are aged or damaged, they need to be manually disassembled and repaired.

[0003] Existing cutting heads for mold processing, such as authorization announcement No. CN219093672U, disclose a cutting tool that is easy to install and disassemble. The sliding plate is driven upward by a push plate, and the sliding plate drives the sliding rod upward, prompting the sliding rod to disengage from the second plug hole, thereby releasing the fixation of the sliding rod fixing rod. Then, the pull ring is pulled, and the pull ring drives the fixing rod to move horizontally, prompting the fixing rod to disengage from the fixing hole, thereby releasing the fixation of the fixing rod to the connecting rod and the tool body. However, during operation, it is still necessary to lift the auxiliary lifting plates on both sides separately and then pull the fixing rod outward separately, which is still not convenient enough. Utility Model Content

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A cutting tool head for mold processing, comprising a tool head seat and a tool head body, the tool head seat comprising a connecting seat, a card slot being provided inside the connecting seat, the tool head body being movably installed inside the card slot, a mounting hole being provided on the outside of the connecting seat, a fixing component being movably clamped inside the mounting hole, a limiting component being fixedly installed outside the connecting seat, the fixing component comprising a slider movably clamped in the mounting hole, the inner side of the slider being fixedly connected to a card block penetrating the inner side of the connecting seat, a spring being movably sleeved on the outer side of the slider, a guide ramp being provided on the outer side of the slider, the limiting component comprising a sleeve fixedly connected to the outside of the connecting seat, a limiting ring and a limiting plate being movably clamped inside the sleeve, and the bottom of the limiting ring being fixedly connected to a limiting plate penetrating the bottom of the sleeve and located outside the connecting seat.

[0006] A further improvement of the technical solution of the present utility model is that the position of the limiting plate corresponds to the position of the mounting hole, and the limiting plate abuts against the outside of the mounting hole.

[0007] A further improvement of the technical solution of the present utility model is that: the cutter head body comprises a cutter body, and a fixing groove and a limiting groove are provided on the upper outer side of the cutter body.

[0008] A further improvement of the technical solution of the present utility model is that the clamping block penetrates the mounting hole and is movably clamped in the interior of the fixing groove.

[0009] A further improvement of the technical solution of the present invention is that: a fixing ring is threadedly connected to the top of the outer sleeve, and the fixing ring is movably sleeved on the outside of the connecting seat.

[0010] A further improvement of the technical solution of the present invention is that: an ear plate is fixedly connected to the outer side of the limiting ring, and an opening corresponding to the ear plate is opened on the side of the outer sleeve.

[0011] A further improvement of the technical solution of the present invention is that the spring is movably connected to the slider and the interior of the mounting hole.

[0012] A further improvement of the technical solution of the present utility model is that a positioning convex strip is provided on the inner side of the clamping slot, and the positioning convex strip is movably clamped in the inner side of the limiting slot.

[0013] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0014] 1. The utility model provides a cutting tool head for mold processing. The ear plate is lifted upward by the fingers to drive the limit ring to move upward along the inner side of the outer sleeve, so that the limit ring drives the limit plate to move upward to squeeze the second spring, thereby causing the limit plate to leave the mounting holes arranged equidistantly in the outer ring of the connecting seat. The spring 1 located between the mounting hole and the slider releases the elastic force to push the slider to drive the clamping block to move outward, so that the clamping block is separated from the inside of the fixed groove, and the cutter body is pulled downward from the slot, thereby facilitating disassembly.

[0015] 2. The utility model provides a cutting head for mold processing, which limits the mounting hole and the slider inside the mounting hole from the outside by means of an upper and lower movable adjustment through a limit plate, thereby reducing the impact of the rotation of the cutter head body during use and still ensuring the stability of the limit.

[0024] By lifting the ear plate 46 upward with your fingers, the limit ring 42 is driven to move upward along the outer sleeve 41, so that the limit ring 42 drives the limit plate 43 to move upward to squeeze the spring 2 44, so that the limit plate 43 leaves the mounting hole 13 located in the outer ring of the connecting seat 11 and is evenly spaced. The spring 1 33 located between the mounting hole 13 and the slider 31 releases the elastic force to push the slider 31 to drive the block 32 to move outward, so that the block 32 is separated from the inside of the fixing groove 22, and the cutter body 21 is pulled downward from the slot 12, thereby facilitating disassembly.

[0025] like Figure 2 and Figure 5 As shown, the position of the limiting plate 43 corresponds to the position of the mounting hole 13 , and the limiting plate 43 abuts against the outside of the mounting hole 13 .

[0026] The position of the limiting plate 43 corresponds to the mounting hole 13 , so that the limiting plate 43 abuts against the outside of the mounting hole 13 to limit the fixing assembly 3 located in the mounting hole 13 .

[0027] like Figure 2 and Figure 3 As shown, the cutter head body 2 includes a cutter body 21 , and a fixing groove 22 and a limiting groove 23 are formed on the upper outer side of the cutter body 21 .

[0028] The clamping block 32 penetrates the mounting hole 13 and is movably clamped in the interior of the fixing groove 22 .

[0029] By correspondingly arranging the fixing groove 22 and the clamping block 32 , the limiting groove 23 penetrates the mounting hole 13 and is clamped into the fixing groove 22 to limit and fix the blade body 21 , thereby facilitating installation.

[0030] like Figure 5 As shown, a fixing ring 45 is threadedly connected to the top of the outer sleeve 41 , and the fixing ring 45 is movably sleeved on the outside of the connecting seat 11 .

[0031] The fixing ring 45 connected by threads can be disassembled to facilitate the disassembly of the inner part of the outer sleeve 41 for easy maintenance.

[0035] The spring 1 33 is clamped in the position between the slider 31 and the inside of the mounting hole 13, so that the limit plate 43 moves upward to release the elastic force of the spring 1 33 to push the slider 31 and the block 32 outward, thereby releasing the fixation of the cutter head body 2.

[0036] like Figure 3 As shown, a positioning ridge 14 is provided on the inner side of the slot 12 , and the positioning ridge 14 is movably engaged with the inner side of the limiting slot 23 .

[0037] The limiting groove 23 corresponds to the positioning ridge 14, so that the blade body 21 is conveniently positioned and fixed in the slot 12, and at the same time, it provides stable lateral load to ensure stability in use.

[0038] The following is a detailed description of the working principle of the cutting head used for mold processing.

[0039] like Figures 1 to 5As shown, during installation, the limit ring 42 and the limit plate 43 are moved upward by lifting the ear plate 46, and the knife body 21 is inserted into the card slot 12 by aligning the positioning ridge 14 in the card slot 12 with the outer limit groove 23. Then, the spring 2 44 is released by loosening the ear plate 46 to push the limit ring 42 to drive the limit plate 43 to move downward. The limit plate 43 is pressed against the outer side of the guide slope 34. The downward movement of the limit plate 43 pushes the slider 31 to drive the card block 32 to slide inward along the installation hole 13 to squeeze the spring 1 33, and the card block 32 is clamped into the fixed The tool 21 is fixed in the fixed groove 22. When disassembling, the ear plate 46 is lifted upward by the fingers to drive the limit ring 42 to move up along the outer sleeve 41, so that the limit ring 42 drives the limit plate 43 to move up and squeeze the spring 2 44, so that the limit plate 43 leaves the mounting hole 13 located in the outer ring of the connecting seat 11 and is equidistantly arranged. The spring 1 33 located between the mounting hole 13 and the slider 31 releases the elastic force to push the slider 31 to drive the block 32 to move outward, so that the block 32 is separated from the inside of the fixed groove 22, and the cutter body 21 is pulled downward from the slot 12, thereby facilitating disassembly.

[0040] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
