Description

Technical Field

[0001] This utility model relates to the field of cemented carbide cutting tools with positioning structures, specifically a cemented carbide cutting tool with a positioning structure. Background Technology

[0002] As the name suggests, these are cutting tools made of cemented carbide, a material with extremely high hardness. This material has advantages such as high strength, good toughness, wear resistance, and corrosion resistance, and is widely used in cutting processes.

[0003] For example, a carbide cutting tool with a positioning structure, authorized by publication number "CN221184749U", has a positioning part above the upper plate, a lower plate slidably connected to the lower half of the bottom shell, two cutting tools below the lower plate, and a linkage part above the lower plate. This invention allows the cutting tool to move upwards when the bottom shell is released from its fixed position, thus preventing the cutting tool from colliding with the workpiece during movement and facilitating operation. However, in the use of carbide cutting tools, due to the presence of adjustment components, the overall weight is relatively large. Furthermore, the connection between the cutting tool and the entire tool assembly cannot be replaced, requiring the entire carbide cutting tool to be replaced after damage, increasing the replacement cost and limiting the usability of carbide cutting tools. Utility Model Content

[0004] The purpose of this invention is to address the problem of increased replacement costs and limited use of carbide cutting tools by proposing a carbide cutting tool with a positioning structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a carbide cutting tool with a positioning structure, including a cross plate and a through groove. The inner wall of the cross plate is machined with a through groove, and the inner wall of the through groove is connected to a disassembly and assembly structure. Positioning structures are respectively connected to the top left and right sides of the cross plate. Second round rods are respectively inserted into the round openings on the front and rear sides of the cross plate, and second handles are fixed to the outer side of the second round rods.

[0007] Preferably, the disassembly structure includes a bracket and a first protective pad. The upper outer wall of the bracket is slidably connected to the inner wall of the through groove. The left side of the inner wall of the bracket is fixedly connected to the left side of the first protective pad. A screw is threadedly connected to the right side of the bracket. A straight plate is rotatably connected to the left side of the outer wall of the screw. A second protective pad is fixedly connected to the left side of the straight plate. A first handle is fixedly connected to the right side of the screw.

[0008] Preferably, the right side of the first pad is pressed against a blade, and the top right side of the blade is pressed against the left side of the second pad.

[0009] Preferably, the front and rear circular openings of the bracket are respectively inserted into the inner side of the outer wall of the two second circular rods, and the top of the straight plate is attached to the top of the inner wall of the bracket.

[0010] Preferably, the positioning structure includes a vertical plate and a sleeve plate. The bottom of the vertical plate is fixedly connected to the top of the horizontal plate. The outer wall of the vertical plate is slidably connected to the inner wall of the sleeve plate. A protrusion is fixedly connected to the outer wall of the sleeve plate. A first round rod is inserted into the front of the sleeve plate. A round block is fixedly connected to the front of the first round rod. The rear of the outer wall of the first round rod is inserted into the round opening on the front of the vertical plate.

[0011] Preferably, the top front and rear sides of the horizontal plate are fixedly connected to concave plates.

[0012] The present invention provides a carbide cutting tool with a positioning structure, which has the following advantages: Through the disassembly and assembly structure, the first handle, along with the screw, rotates to the right via the bracket. The rotating screw moves the straight plate, which is in contact with the top of the inner wall of the bracket, to the right. Simultaneously, the straight plate moves to the right along with the second protective pad, causing the second protective pad to detach from the cutting tool. The cutting tool is then removed, allowing the upper left side of the new cutting tool's outer wall to align with the right side of the first protective pad. Then, the first handle rotates to the left along with the screw, causing the screw to move the straight plate to the left, bringing the straight plate and the first protective pad into contact with the cutting tool. This completes the cutting tool replacement, reducing the replacement cost of carbide cutting tools and eliminating the limitations of carbide cutting tool usage. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] Please see Figure 1-5 In this embodiment, a carbide cutting tool with a positioning structure includes a horizontal plate 1 and a through groove 8. The inner wall of the horizontal plate 1 is machined with the through groove 8, and the inner wall of the through groove 8 is connected to a disassembly and assembly structure 2. The top left and right sides of the horizontal plate 1 are respectively connected to positioning structures 3. The front and rear round openings of the horizontal plate 1 are respectively inserted into the second round rod 4. The outer side of the second round rod 4 is fixed with a second handle 5, which facilitates the insertion and removal of the second round rod 4.

[0022] The disassembly and assembly structure 2 includes a bracket 201 and a first protective pad 202. The upper outer wall of the bracket 201 is slidably connected to the inner wall of the through groove 8. The bracket 201 slides left and right through the inner wall of the through groove 8 under force. The left side of the inner wall of the bracket 201 is fixedly connected to the left side of the first protective pad 202. The first protective pad 202 is a rubber plate. The right side of the bracket 201 is threadedly connected to a screw 203. The screw 203 rotates left and right through the round opening on the right side of the bracket 201 under force. The left side of the outer wall of the screw 203 is rotatably connected to a straight plate 204. The left side of the outer wall of the screw 203 rotates through the bearing in the round opening on the right side of the straight plate 204 under force.

[0023] A second protective pad 205 is fixed to the left side of the straight plate 204. The second protective pad 205 is a rubber plate. A first handle 206 is fixed to the right side of the screw 203. The first handle 206 facilitates the rotation of the screw 203. A blade 6 is pressed against the right side of the first protective pad 202. The blade 6 is made of hard aluminum alloy. The top right side of the blade 6 is pressed against the left side of the second protective pad 205. The front and rear round openings of the bracket 201 are respectively inserted into the inner side of the outer wall of the two second round rods 4. The top of the straight plate 204 is in contact with the top of the inner wall of the bracket 201.

[0024] By using the disassembly and assembly structure 2, the first handle 206, along with the screw 203, rotates to the right via the bracket 201. The rotating screw 203, along with the straight plate 204, moves to the right against the top of the inner wall of the bracket 201. Simultaneously, the straight plate 204, along with the second protective pad 205, moves to the right, causing the second protective pad 205 to detach from the blade 6. Then, the blade 6 is removed, so that the upper left side of the outer wall of the new blade 6 aligns with the right side of the first protective pad 202. Next, the first handle 206 rotates to the left with the screw 203, causing the screw 203, along with the straight plate 204, to move to the left, causing the straight plate 204, along with the first protective pad 202, to press against the blade 6, thus completing the replacement of the blade 6. This reduces the replacement cost of carbide cutting tools and eliminates the limitations of using carbide cutting tools.

[0025] The positioning structure 3 includes a vertical plate 301 and a sleeve plate 302. The bottom of the vertical plate 301 is fixedly connected to the top of the horizontal plate 1. The outer wall of the vertical plate 301 is slidably connected to the inner wall of the sleeve plate 302. The vertical plate 301 slides up and down through the inner wall of the sleeve plate 302 under force. A protrusion 303 is fixedly connected to the outer wall of the sleeve plate 302. A first round rod 304 is inserted into the front of the sleeve plate 302. A round block 305 is fixedly connected to the front of the first round rod 304. The round block 305 facilitates the movement of the first round rod 304 back and forth. The rear of the outer wall of the first round rod 304 is inserted into the round opening on the front of the vertical plate 301. A concave plate 7 is fixedly connected to both the front and rear sides of the top of the horizontal plate 1.

[0026] Working principle:

[0027] Carbide cutting tool installation and use:

[0028] First, make the protrusions 303 on both sides fit against the external column. Then, the bolts are threaded from the inside to the outside through the threaded opening on the outer wall of the protrusion 303 and connected to the column. At this time, the carbide tool is fixed. The output end of the telescopic device can be fixed to the top of the concave plate 7. Alternatively, the concave plate 7 can be controlled by hand. The first round rod 304 is pulled forward by the round block 305, so that the rear of the outer wall of the first round rod 304 is separated from the round opening on the front of the upright plate 301. At this time, the horizontal plate 1 can slide up and down on the inner wall of the sleeve plate 302 with the upright plate 301. At this time, the carbide tool loses its positioning. As the horizontal plate 1 moves downward, it cooperates with the disassembly and assembly structure 2 to move the blade 6 downward, so that the blade 6 cuts the object.

[0029] Carbide tool position adjustment:

[0030] With the second handle 5 pulling the second round rod 4 outward, the second round rod 4 is disengaged from the bracket 201 and the horizontal plate 1. Then the bracket 201 slides left and right on the inner wall of the through groove 8 to adjust its position. At this time, the bracket 201 moves with the fixed blade 6. Then the second round rod 4 passes through the corresponding round opening on the outer wall of the horizontal plate 1 until the inner side of the outer wall of the second round rod 4 is inserted into the round opening on the outer wall of the bracket 201, thus fixing the position of the bracket 201 and fixing the position of the blade 6.

[0031] Carbide cutting tool insert replacement:

[0032] When the blade 6 is damaged and needs to be replaced, the first handle 206, along with the screw 203, is rotated to the right via the bracket 201. The rotating screw 203 moves the straight plate 204 to the right, adhering to the top of the inner wall of the bracket 201. At the same time, the straight plate 204 moves the second protective pad 205 to the right, causing the second protective pad 205 to detach from the blade 6. Then, the blade 6 is removed, so that the upper left side of the outer wall of the new blade 6 is aligned with the right side of the first protective pad 202. Then, the first handle 206 is rotated to the left with the screw 203, causing the screw 203 to move the straight plate 204 to the left, so that the straight plate 204, along with the first protective pad 202, is pressed against the blade 6, thus completing the replacement of the blade 6.

[0033] Example 2:

[0034] Please see Figure 1-5 In this embodiment, a cemented carbide cutting tool with a positioning structure also includes a top plate 9, the bottom of the two top plates 9 being fixedly connected to the top of the two vertical plates 301 respectively.

[0035] Working principle:

[0036] When the upright plate 301 slides downward on the inner wall of the sleeve plate 302, the top plate 9 plays a restrictive role. The bottom outer side of the top plate 9 can contact the top of the sleeve plate 302 to prevent the upright plate 301 from leaving the interior of the sleeve plate 302.

[0037] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
