Description

Technical Field

[0001] The present invention relates to the technical field of cutting tools, and more specifically, to a cutting tool for machining a compressor cylinder block. Background Art

[0002] A cutting tool is a tool used for cutting in machining, also known as a cutting tool. The vast majority of cutting tools are for machine use, but there are also hand-held ones. Since the cutting tools used in machining basically cut metal materials, the term "cutting tool" is generally understood as a metal cutting tool. In the production and manufacturing process of a compressor cylinder block, generally, a machine tool needs to further process a rough blank through a cutting tool to form holes and grooves.

[0003] Most of the existing cutting tools used for machining a compressor cylinder block can only machine one type of hole and groove. When it is necessary to adjust the machining position and range, generally, it is carried out by adjusting the position of the main shaft or the compressor cylinder block, but this will cause the main shaft to have a moving space, affecting the stability of the main shaft or the cylinder block. For some changes in the hole diameter, it can only be replaced by disassembling and installing the cutting tool to meet the machining requirements, but this method is time-consuming and laborious, affecting the machining efficiency of the compressor cylinder block.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention;

[0036] Please refer to Figures 1 to 4 , in the present invention, a tool for machining a compressor cylinder block includes a tool holder 1 and a blade 2. A pressure rod 3 is slidably connected to the inner side of the tool holder 1. An adjusting screw rod 4 is threadedly connected to the inner side of the pressure rod 3. The adjusting screw rod 4 is rotatably connected to the tool holder 1. A first T-shaped sliding groove 5 is formed at the bottom of the tool holder 1. The top of the blade 2 is slidably connected to the first T-shaped sliding groove 5. The bottom end of the pressure rod 3 penetrates through the tool holder 1 and is slidably connected to an inclined slider 6. The inclined slider 6 is mounted on the blade 2. A connecting ring 7 is mounted on the top of the tool holder 1, and an air duct is externally connected to the connecting ring 7. A dial 8 is fixedly mounted on the top of the adjusting screw rod 4. A sleeve 9 is integrally formed on the top of the tool holder 1. The dial 8 is located inside the sleeve 9 and is rotatably connected to the inner wall of the sleeve 9 and is sealed;

[0037] The connecting ring 7 includes a fixed ring 71. The fixed ring 71 is fixedly mounted on the tool holder 1. A rotating ring 72 is rotatably connected to the fixed ring 71. A shaft seal is mounted at the connection between the rotating ring 72 and the fixed ring 71. The air duct is mounted on the rotating ring 72. Two through pipes 73 are fixedly connected between the sleeve 9 and the fixed ring 71.

[0038] In the present invention, by externally connecting an air pump or other equipment through the air duct, air can be inflated or evacuated into the cavity between the fixed ring 71 and the rotating ring 72, thereby changing the air pressure inside the rotating ring 72. The cavity is connected to the inside of the sleeve 9 through the through pipes 73, changing the blowing direction of the two through pipes 73 into the inside of the sleeve 9, driving the dial 8 to rotate, thereby rotating the adjusting screw rod 4. Using the threaded connection between the adjusting screw rod 4 and the pressure rod 3, the pressure rod 3 is driven to move up and down. Since the bottom of the pressure rod 3 contacts the inclined slider 6 mounted on the blade 2, the pressure rod 3 is used to push the blade 2 and the inclined slider 6 to move horizontally left and right, changing the position of the cutting edge 22 of the blade 2 and adjusting the degree of deviation of the cutting edge 22 from the bottom of the tool holder 1. When the tool holder 1 is mounted on a machine tool and rotates, the machining range of the tool can be changed, and it can be adjusted according to the machining requirements of different holes and grooves on the compressor cylinder block without the movement of the main shaft, thereby ensuring the stability of the main shaft;

[0039] At the same time, while the tool holder 1 is rotating, since the air duct is mounted on the rotatable rotating ring 72, it will not affect the rotation of the tool holder 1 and other structures, and the air pressure adjustment function is ensured. Thus, during the rotation of the tool holder 1 driving the blade 2, the blade 2 is driven to move, thereby achieving the purpose of changing the feed rate. There is no need to stop the machine for adjustment. At the same time, the position or range of the hole and groove can be changed, thereby increasing the convenience of using the tool, saving disassembly and assembly, and improving the machining efficiency of the compressor cylinder block.

[0040] Please refer to Figure 2 And Figure 3, wherein: a second T-shaped groove 61 is formed on the right side of the inclined slider 6, and a T-shaped slider 31 is integrally formed at the bottom end of the pressure rod 3. The T-shaped slider 31 is located inside the second T-shaped groove 61 and is slidably connected to the inner wall of the second T-shaped groove 61.

[0041] In the present invention, through the limitation of the second T-shaped groove 61 and the T-shaped slider 31, the stability of the connection between the bottom of the pressure rod 3 and the inclined slider 6 is achieved. While restricting the inclined slider 6, the movement range of the inclined slider 6 is stabilized.

[0042] Please refer to Figure 2 and Figure 3 , wherein: convex blocks 21 are integrally formed on the blade 2 at equal intervals, and grooves 62 matching the convex blocks 21 are formed on the inclined slider 6. The convex blocks 21 are embedded inside the grooves 62.

[0043] In the present invention, through the matching of the convex blocks 21 and the grooves 62, the relative left-right sliding between the blade 2 and the inclined slider 6 can be restricted. Together with the restriction of the second T-shaped groove 61 and the T-shaped slider 31, the inclined slider 6 can be fixed on the restricting blade 2. When it is necessary to change the position of the inclined slider 6 on the restricting blade 2, by moving the T-shaped slider 31 upward to disengage it from the second T-shaped groove 61, the inclined slider 6 can be conveniently disassembled. At the same time, by installing the inclined slider 6 at the positions of other convex blocks 21 on the restricting blade 2, the relative position between the inclined slider 6 and the blade 2 can be changed, thereby further increasing the adjustment range of the blade 2 to meet the processing requirements of the compressor cylinder block.

[0044] Please refer to Figure 2 and Figure 3 , wherein: the blade 2 includes a tool tip 22 and a tool body 23. The convex blocks 21 are integrally formed on the tool body 23, and the tool tip 22 is located at the bottom of the left side of the tool body 23.

[0045] In the present invention, through the tool body 23, the position at the bottom of the tool holder 1 can be stabilized, ensuring the stability and strength of the tool tip 22, and at the same time, more convex blocks 21 can be provided to increase the installation positions of the inclined slider 6 on the blade 2.

[0046] Please refer to Figure 4 , wherein: the dial 8 includes a sealing plate 81, and uniformly distributed dial plates 82 are fixedly connected to the top of the sealing plate 81. The outer sides of the dial plates 82 are in contact with the inner wall of the sleeve 9 and are subjected to a sealing air treatment.

[0047] In the present invention, through the connection of the two through pipes 73 and the sleeve 9, one through pipe 73 can be inflated and the other can be evacuated. By using the negative pressure difference to drive the rotation of the dial plate 82, and by changing the suction functions of the two through pipes 73, the sealing plate 81 can be driven to rotate forward and backward, and the adjusting screw 4 can be driven to rotate by the sealing plate 81.

[0048] Please refer to Figure 1 and Figure 2 , where: the gap between the fixed ring 71 and the rotating ring 72 is an annular cavity 74. A partition 75 is arranged inside the annular cavity 74, and the partition 75 is integrally formed on the fixed ring 71. The outer side of the partition 75 is rotatably connected to the rotating ring 72 and is sealed. The annular cavity 74 is divided into two air cavities by the partition 75, and two through pipes 73 are respectively communicated with the interiors of the two air cavities.

[0049] In the present invention, the annular cavity 74 facilitates the flow of gas, and the two air cavities separated by the partition 75 enable the two air ducts to make the air pressures of the two through pipes 73 different, so as to adjust the air pressure adjustment function of the two through pipes 73 on the inside of the sleeve 9.

[0050] Please refer to Figure 2 and Figure 3 , where: the front view section of the inclined slider 6 is a right trapezoid. The second T-shaped groove 61 is opened on the inclined surface of the inclined slider 6, and the bottom end of the pressure rod 3 is provided with a contact surface matching the inclined surface of the inclined slider 6.

[0051] In the present invention, through the contact between the contact surface at the bottom end of the pressure rod 3 and the inclined surface of the inclined slider 6, when the pressure rod 3 is pressed down, the inclined slider 6 can be moved left and right.

[0052] Please refer to Figure 2 , where: a stable sliding groove 11 is opened inside the tool holder 1. A limiting strip 32 is integrally formed on the pressure rod 3, and the limiting strip 32 is located inside the stable sliding groove 11 and is slidably connected to the inner wall of the stable sliding groove 11.

[0053] In the present invention, through the cooperation of the stable sliding groove 11 and the limiting strip 32, the rotation of the pressure rod 3 is restricted, avoiding that the pressure rod 3 rotates with the adjusting screw 4 and cannot perform the lifting function, and the structure is scientifically reasonable.

[0054] Please refer to Figure 4 , where: the two through pipes 73 are arranged perpendicular to each other and deviate from the center of the sealing plate 81.

[0055] In the present invention, the connection between the through pipe 73 and the sleeve 9 deviates from the center of the sealing plate 81, which can facilitate driving the sealing plate 81 to rotate.

[0056] Please refer to 4, where: the sealing plate 81 is fixedly installed on the top of the adjusting screw 4 and is rotatably connected to the inner wall of the sleeve 9. A shaft seal is installed between the sealing plate 81 and the sleeve 9.

[0057] In the present invention, the sealing plate 81 plays a role in restricting the position of the adjusting screw 4, and at the same time can seal the internal space of the sleeve 9, so as to generate negative pressure and facilitate driving the sealing plate 81 to rotate through the dial 82.

[0058] Working principle: By externally connecting devices such as an air pump through an air duct, it is possible to inflate or deflate the cavity between the fixed ring 71 and the rotating ring 72, thereby changing the air pressure inside the rotating ring 72. The cavity is connected to the inside of the sleeve 9 through the through pipe 73, and the blowing directions of the two through pipes 73 into the inside of the sleeve 9 are changed, driving the dial 8 to rotate, thereby causing the adjusting screw 4 to rotate. Using the threaded connection between the adjusting screw 4 and the pressure rod 3, the pressure rod 3 is driven to move up and down. Since the bottom of the pressure rod 3 contacts the inclined slider 6 installed on the blade 2, the pressure rod 3 is used to push the blade 2 and the inclined slider 6 to move horizontally left and right, changing the position of the cutting head 22 of the blade 2 and adjusting the degree of deviation of the cutting head 22 from the bottom of the tool holder 1. When the tool holder 1 is installed on the machine tool and rotates, the machining range of the tool can be changed, and it can be adjusted according to the machining requirements of different holes and grooves on the compressor cylinder block without the movement of the main shaft, thereby ensuring the stability of the main shaft. At the same time, while the tool holder 1 is rotating, since the air duct is installed on the rotatable rotating ring 72, it will not affect the rotation of other structures such as the tool holder 1 and ensures the air pressure adjustment function. Thus, during the rotation of the tool holder 1 driving the blade 2, the blade 2 is driven to move, thereby achieving the purpose of changing the feed rate without stopping for adjustment. At the same time, the position or range of the hole and groove can be changed, thereby increasing the convenience of using the tool, saving disassembly and assembly, and improving the machining efficiency of the compressor cylinder block.

[0059] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
