Description

Technical Field

[0001] This utility model relates to the field of grooving tool technology, specifically a high-hardness grooving tool for machining chip-breaking grooves. Background Technology

[0002] Currently, globally, machining, as a fundamental process in manufacturing technology, is experiencing rapid development. With this advancement, it has entered a new phase focused on high-speed cutting and the development of new cutting processes and machining methods. Metal cutting tools, as indispensable supporting equipment for CNC machine tools, have entered the development stage of CNC tooling, driven by CNC machining technology, exhibiting characteristics of high efficiency, high precision, and high reliability.

[0003] According to announcement number CN 206492978 U, a grooving knife includes a handle, a clamping part integrally formed with the handle, and a cutting head. The clamping part includes a fixing part, a first clamping block, and a second clamping block with a height lower than the first clamping block. The fixing part is connected to the handle. A clamping space for clamping the cutting head is formed between the first clamping block and the second clamping block, and a locking block is provided on each adjacent surface. The cutting head has a locking groove on both sides for the locking block to be engaged. The fixing part has a groove in the middle that passes through both sides for deformation. The bottom of the groove expands to form a first pressure relief groove. A fastening bolt is provided on the fixing part perpendicular to the groove. One side of the fixing part has a threaded hole that mates with the fastening bolt, and the other side has a through hole for the fastening bolt to pass through.

[0004] The grooving cutter insert is fixed in a groove that fits the insert by fastening bolts. This method can make it difficult to place the insert in the groove if there are slight errors in the groove or insert machining, or gaps may exist between the insert and the groove's perimeter, causing the cutter head to wobble during cutting and resulting in poor cutting performance. Furthermore, the grooving cutter is still fixed to the tool holder using traditional bolts. This method results in a small contact area between the bolt and the grooving cutter, which can cause the cutter to slip and fall off during work. Utility Model Content

[0005] The purpose of this invention is to provide a high-hardness grooving tool for machining chip-breaking grooves, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-hardness grooving tool for machining chip-breaking grooves, comprising a grooving tool body, wherein a wear-resistant mechanism is provided on the surface of the grooving tool body;

[0007] The wear-resistant mechanism includes an L-plate, a pressure block fixedly connected to the top of the L-plate, the L-plate being disposed on the surface of the slotting cutter body, fixing plates symmetrically fixedly connected to the left and right sides of the L-plate, a guide rod fixedly connected to the front of the fixing plate near the top, a clamping plate slidably connected to the surface of the guide rod, a limiting plate fixedly connected to the front end of the surface of the guide rod, a spring sleeved between the clamping plate and the limiting plate on the surface of the guide rod, and an anti-slip pad fixedly connected to the top inside the L-plate.

[0008] Preferably, the inner back side of the L-plate is in contact with the back side of the slotting blade body.

[0009] Preferably, the front end of the spring is fixedly connected to the front of the limiting plate, and the rear end of the spring is fixedly connected to the front of the clamping plate.

[0010] Preferably, the bottom of the anti-slip pad is in contact with the top of the slotting knife body.

[0011] Preferably, there are three sets of pressure blocks, which are fixedly connected to the top of the L-plate at equal intervals, and the pressure blocks correspond to the fastening bolts in the knife holder.

[0012] Compared with the prior art, this utility model provides a high-hardness grooving tool for machining chip-breaking grooves, which has the following beneficial effects:

[0013] This high-hardness grooving cutter for machining chip grooves involves coating the tool holder surface with an anti-slip agent, then pulling the pull plate to increase the distance between the pull plate and the L-plate. The movement of the pull plate compresses the spring, and then the grooving cutter body is placed inside the L-plate, ensuring the bottom of the anti-slip pad is in contact with the top of the grooving cutter body. The pull plate is then released, causing it to move to one side of the grooving cutter body due to the spring force, clamping the L-plate and the clamping plate. This limits the L-plate, preventing it from easily slipping off the surface of the grooving cutter body. The grooving cutter is then placed inside the tool holder and secured with fastening bolts. The fastening bolts press against the pressure block, indirectly increasing the contact area between the fastening bolts and the grooving cutter body to improve friction and prevent the grooving cutter body from easily slipping out of the tool holder during operation.

[0022] This utility model provides the following technical solution: Example

[0023] Please see Figure 1-4 This utility model provides a technical solution: a high-hardness grooving tool for processing chip grooves, including a grooving tool body 1, and a wear-resistant mechanism 2 is provided on the surface of the grooving tool body 1;

[0024] The wear-resistant mechanism 2 includes an L-plate 21. A pressure block 22 is fixedly connected to the top of the L-plate 21. The L-plate 21 is set on the surface of the slotting cutter body 1. Fixing plates 23 are fixedly connected symmetrically on the left and right sides of the L-plate 21. A guide rod 24 is fixedly connected to the front of the fixing plate 23 near the top. A clamping plate 25 is slidably connected to the surface of the guide rod 24. A limiting plate 26 is fixedly connected to the front end of the surface of the guide rod 24. A spring 27 is sleeved between the clamping plate 25 and the limiting plate 26 on the surface of the guide rod 24. An anti-slip pad 28 is fixedly connected to the top inside the L-plate 21.

[0025] The inner back of L plate 21 is in contact with the back of the slotting knife body 1.

[0026] The front end of the spring 27 is fixedly connected to the front of the limiting plate 26, and the rear end of the spring 27 is fixedly connected to the front of the clamping plate 25.

[0027] The bottom of the anti-slip pad 28+ fits against the top of the slotting knife body 1.

[0028] There are three sets of pressure blocks 22, which are fixedly connected to the top of L plate 21 at equal intervals. The pressure blocks 22 correspond to the fastening bolts in the tool holder.

[0029] In actual operation, when this device is used, an anti-slip agent is applied to the surface of the tool holder. Then, the pull plate is pulled to increase the distance between the pull plate and the L plate 21. The movement of the pull plate will compress the spring 27. Then, the grooving knife body 1 is placed inside the L plate 21, so that the bottom of the anti-slip pad 28 is in contact with the top of the grooving knife body 1. Then, the pull plate is released. At this time, the pull plate will move to one side of the grooving knife body 1 by the elastic force of the spring 27, so that the L plate 21 and the clamping plate 25 clamp the grooving knife body 1, thereby limiting the L plate 21 and preventing the L plate 21 from easily falling off the surface of the grooving knife body 1. Then, the grooving knife is placed in the tool holder and the grooving knife body 1 is fixed with the fastening bolts. The fastening bolts press down on the pressure block 22, thereby indirectly increasing the contact area between the fastening bolts and the grooving knife body 1, thereby improving the friction and preventing the grooving knife body 1 from easily slipping out of the tool holder during operation.
