Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a cutting tool for machining deep grooves on end faces. Background Technology

[0002] Deep groove cutting tools are used to carve deep and narrow grooves on the end face of a workpiece, such as sealing grooves, guide rail grooves, or cooling channels. Deep groove cutting tools are particularly suitable for applications requiring deep cutting on the end face. They are specially designed to complete the cutting of deep grooves in one go, reducing machining time and steps and improving production efficiency. However, most deep groove cutting tools in the current technology still have problems that need to be solved.

[0003] In the existing technology, most end-face deep groove machining tools and tool bodies are generally designed as separate parts, and the tool and tool body are usually fixed by screws. When changing or adjusting the tool, the screws need to be removed, which is cumbersome and reduces efficiency, especially in mass production. Therefore, it is necessary to design an end-face deep groove machining tool to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a deep groove machining tool for end faces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A deep groove machining tool includes a tool body, a fixed base on one side of the tool body, three cutting blades fixedly connected to the fixed base, two positioning grooves and two slots on the fixed base, an installation groove on the tool body, a movable block disposed in the installation groove, the movable block being slidably connected to the tool body, an I-shaped block fixedly connected to the movable block on the side of the movable block away from the fixed base, a round tube sleeved on the I-shaped block, the round tube being rotatably connected to the I-shaped block, positioning rods disposed in each of the two positioning grooves, both positioning rods being fixedly connected to the tool body, the positioning rods being adapted to the positioning grooves, pins disposed in each of the two slots, both pins being fixedly connected to the movable block, a handle fixedly connected to the outer wall of the round tube, a straight groove and a retaining groove on the tool body, the handle being disposed in the retaining groove, the handle being adapted to the retaining groove. By employing positioning grooves and positioning rods to position the fixed seat, and slots and pins to restrict the position of the fixed seat, the fixed seat can be positioned simply by fitting it onto the positioning rod, and its position can be restricted by inserting the pin into the slot, allowing the cutting tool to be installed. Removing the pin from the slot releases the restriction, allowing the fixed seat to be removed. This effectively solves the problem mentioned in the background art that most existing end-face deep groove machining tools and tool bodies are generally designed as separate parts, usually fixed by screws. When changing or adjusting the tool, the screws need to be removed, which is cumbersome and inefficient, especially in mass production. This technology enables quick assembly and disassembly without the cumbersome disassembly steps of screws and nuts, significantly shortening tool change time and improving assembly and disassembly efficiency.

[0007] As a further embodiment of this utility model, both ends of the card slot are provided with sliding grooves, and rollers are provided in both sliding grooves. The two rollers are connected to the same fixed shaft, and the rollers are rotatably connected to the fixed shaft. A round rod is fixedly connected to the outer wall of the fixed shaft, and a ring is fixedly connected to the outer wall of the round rod. A spring is provided at the bottom of the ring, and the spring is sleeved on the round rod. A square plate and a cylinder are sleeved on the round rod, and the spring is located on the top of the square plate.

[0008] As a further embodiment of this utility model, a toggle plate is fixedly connected to the outer wall of the round rod.

[0009] As a further embodiment of this utility model, the round rod slidably connects the square plate and the cylinder.

[0010] As a further embodiment of this utility model, L-shaped plates are fixedly connected to the top of both ends of the square plate, and the two L-shaped plates are fixedly connected to the outer wall of the I-shaped block.

[0011] As a further embodiment of this utility model, the same limiting rod is provided on the I-shaped block and the moving block, and the limiting rod is slidably connected to both the I-shaped block and the moving block, while the limiting rod is fixedly connected to the blade body.

[0012] As a further embodiment of this utility model, two reinforcing ribs are fixedly connected to one side of the blade body.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model utilizes a positioning groove and positioning rod to position the fixed seat, and a slot and pin to restrict the position of the fixed seat. Therefore, simply placing the fixed seat on the positioning rod positions it, inserting the pin into the slot restricts its position, allowing the cutting tool to be installed, and removing the pin from the slot releases the restriction, enabling the fixed seat to be removed. This effectively solves the problem mentioned in the background art where most end-face deep groove machining tools and tool bodies are generally designed as separate units, typically fixed by screws. Changing or adjusting the tool requires removing the screws, which is cumbersome, inefficient, and particularly inconvenient in mass production. This invention achieves rapid assembly and disassembly without the tedious steps of screws and nuts, significantly shortening tool change time and improving assembly and disassembly efficiency.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1 - Figure 5A deep groove machining tool for end faces includes a tool body 1, a fixed base 2 on one side of the tool body 1, three blades 3 fixedly connected to the fixed base 2, the three blades 3 being higher in the middle and lower at both ends, each with a 20° rake angle spring; the fixed base 2 has two positioning grooves 201 and two slots 202; the tool body 1 has a mounting groove 4, a moving block 5 is disposed in the mounting groove 4, the moving block 5 is slidably connected to the tool body 1; an I-shaped block 6 is fixedly connected to the moving block 5 on the side away from the fixed base 2, a round tube 7 is sleeved on the I-shaped block 6, the round tube 7 is rotatably connected to the I-shaped block 6; positioning rods 8 are disposed in each of the two positioning grooves 201, both positioning rods 8 are fixedly connected to the tool body 1, the positioning rods 8 are adapted to the positioning grooves 201; pins 501 are disposed in each of the two slots 202, both pins 501 are fixedly connected to the moving block 5; a handle 9 is fixedly connected to the outer wall of the round tube 7; and the tool body 1 has a straight groove 10 and a retaining groove 11. Handle 9 is set in slot 11 and is compatible with slot 11. Due to the use of positioning groove and positioning rod to position the fixed seat, and slot and pin to restrict the position of the fixed seat, the fixed seat can be positioned by putting the fixed seat on the positioning rod, and the position of the fixed seat can be restricted by inserting the pin into the slot. The cutting tool can be installed, and the restriction can be released by removing the pin from the slot. The fixed seat can be removed. This effectively solves the problem mentioned in the background technology that most of the existing end face deep groove machining tools and tool bodies are generally designed as separate parts. The tool and tool body are usually fixed by screw connection. When changing or adjusting the tool, the screws need to be removed, which is cumbersome and reduces efficiency, especially in mass production. This technology realizes the technical effect of quick assembly and disassembly without the cumbersome disassembly steps of screws and nuts, significantly shortening the tool change time and improving assembly and disassembly efficiency.

[0024] In this embodiment, both ends of the slot 11 are provided with sliding grooves 12, and rollers 13 are provided in both sliding grooves 12. The two rollers 13 are connected to the same fixed shaft 14. The rollers 13 are rotatably connected to the fixed shaft 14. A round rod 15 is fixedly connected to the outer wall of the fixed shaft 14. A ring 19 is fixedly connected to the outer wall of the round rod 15. A spring 20 is provided at the bottom of the ring 19. The spring 20 is sleeved on the round rod 15. A square plate 17 and a cylinder 18 are sleeved on the round rod 15. The spring 20 is located on the top of the square plate 17. The elastic force of the spring 20 allows the handle 9 to be stably placed in the slot 11 without the action of external force, ensuring the stability of the fixed seat 2.

[0025] In this embodiment, a toggle plate is fixedly connected to the outer wall of the round rod 15.

[0026] In this embodiment, the round rod 15 is slidably connected to the square plate 17 and the cylinder 18.

[0027] In this embodiment, L-shaped plates 16 are fixedly connected to the top of both ends of the square plate 17, and both L-shaped plates 16 are fixedly connected to the outer wall of the I-shaped block 6.

[0028] In this embodiment, the same limiting rod 21 is provided on the I-shaped block 6 and the moving block 5. The I-shaped block 6 and the moving block 5 are slidably connected to the limiting rod 21, and the limiting rod 21 is fixedly connected to the cutter body 1.

[0029] In this embodiment, two stiffening plates 101 are fixedly connected to one side of the blade body 1. The blade body 1 adopts an arc-shaped design, and the stiffening plates 101 are added to ensure the strength of the arc.

[0030] Working principle: Turning handle 9 downwards compresses roller 13, causing it to move within groove 12. Roller 13 then moves fixed shaft 14, which in turn lowers rod 15. Rod 15 lowers ring 19, compressing spring 20 and causing it to contract. Rod 15 then moves along cylinder 18, ensuring stability during its movement. Moving handle 9 into straight groove 10 laterally moves it away from fixed seat 2, allowing pin 501 to move into mounting groove 4. This allows fixed seat 2 to be fitted onto positioning rod 8, positioning rod 8 within positioning groove 201, thus positioning fixed seat 2. Reversing the direction of handle 9... Moving the handle 9 to the slot 11 position allows the pin 501 to move and insert into the slot 202, thus restricting the position of the fixing seat 2 and fixing the position of the blade 3. When the handle 9 is moved to the slot 11 position, releasing the handle 9 will cause the compressed spring 20 to extend, allowing the ring 19 to rise. The ring 19 will then drive the rod 15 to rise, which in turn will drive the fixed shaft 14 to rise. The fixed shaft 14 will then drive the roller 13 to rise, which will press the handle 9 to rotate upwards and enter the slot 11, thus restricting the position of the handle 9. This ensures the stability of the positions of the I-shaped block 6 and the moving block 5, allowing the pin 501 to be stably positioned within the slot 202, thus completing the assembly work.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
