Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically a cutting tool for high-speed cutting. Background Technology

[0002] Currently, cutting tools are tools used for cutting processes in mechanical manufacturing. The vast majority of tools are machine-made. Since the tools used in mechanical manufacturing are basically used for cutting metal materials, the term "tool" is generally understood as metal cutting tools. According to the needs of manufacturing development, multi-functional composite tools and high-speed and high-efficiency tools will become the mainstream of tool development. The materials used to manufacture tools must have high high-temperature hardness and wear resistance, necessary bending strength, impact toughness and chemical inertness, and good processability.

[0003] The steps for installing cutting tools are to ensure that the tools can be accurately and securely installed on the machine tool and maintain stable cutting performance during machining: 1. Preparation and inspection; 2. Cleaning the locking area; 3. Installing the tool; 4. Adjusting the tool position; 5. Inspection and testing; 6. Recording and maintenance.

[0004] When installing cutting tools, operators need to gently place the tool in the locking position of the machine tool and use the locking device provided by the machine tool (such as screws, levers, etc.) to firmly lock the tool to the machine tool. However, after the tool is installed, it is not easy to check whether the tool is installed firmly. If the tool is not installed firmly, the tool tip can easily fall off, resulting in an accident. Therefore, we propose a cutting tool for high-speed cutting that ensures that the tool can be checked for secure installation after installation. Utility Model Content

[0005] The purpose of this invention is to provide a cutting tool for high-speed cutting, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cutting tool for high-speed cutting, comprising a tool holder, a mounting groove on one side of the tool holder, a connecting hole on one side of the mounting groove, a cutting head detachably mounted in the mounting groove, a stop block fixedly mounted at the middle of one end of the cutting head, and an anti-loosening mechanism mounted on one side inside the tool holder;

[0007] The anti-loosening mechanism includes a piston groove opened in the middle of one side of the tool holder, a piston block movably installed in the mounting groove, a limiting groove connected to the other end of the piston groove, a limiting block slidably installed in the limiting groove, a support rod fixedly installed between the piston block and the limiting block, and a spring sleeved on the outer wall of the support rod. The abutment block and the piston block correspond to each other.

[0008] Optionally, the piston groove and the mounting groove are interconnected, and the two sides of the spring are fixedly installed to the inner wall of the piston groove and the side wall of the piston block, respectively.

[0009] Optionally, a pressure sensor is fixedly installed at one end of the inner side of the limiting groove, and the pressure sensor corresponds to the limiting block.

[0010] By adopting the above technical solution, it is possible to detect whether the cutter head is installed in place.

[0011] Optionally, a groove is provided in the middle of one end of the side wall of the tool holder, and an indicator light is fixedly installed inside one side of the groove. The indicator light is connected to the pressure sensor through a first wire.

[0012] By adopting the above technical solution, the operator can be prompted.

[0013] Optionally, a charging port is fixedly installed on the other side of the groove. The charging port is connected to a rechargeable battery via a second wire, and the rechargeable battery is connected to a pressure sensor via a third wire.

[0014] By adopting the above technical solution, power can be supplied to the pressure sensor and indicator light.

[0015] Optionally, a mounting hole is provided on one side of the cutter head, and the mounting hole corresponds to the mating hole.

[0016] By adopting the above technical solution, the cutter head can be mounted on the tool holder.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] The technical solution of this application involves a stop block on one side of the cutter head engaging with a piston groove on the cutter head when the cutter head is installed on the cutter holder. Since the piston block inside the piston groove is pushed out by the spring, the operator needs to use the stop block to press the piston block into the piston groove when installing the cutter head on the cutter holder, so that the stop block on the cutter head engages with the piston groove, further improving the stability of the cutter head installation. After the cutter head is installed, the supporting force of the spring sleeve on the outer wall of the support rod can continuously compress the cutter head, effectively ensuring that the cutter head will not fall off due to the spring's compressive force if it is not firmly fixed, thus achieving a good anti-fall-off effect.

[0019] A pressure sensor is fixedly installed at one end of the inner side of the limiting groove, and the pressure sensor is connected to the indicator light through the first wire. When the cutter head is installed, the cutter head will squeeze the piston block. Since a support rod is fixedly installed between the piston block and the limiting block, the limiting block moves down synchronously and squeezes the pressure sensor. The pressure sensor under pressure can send a signal to the control processor and turn on the indicator light. Conversely, if the indicator light does not light up, it means that the cutter head is not installed in place. Attached Figure Description

[0024] Please see Figure 1-2 The present invention provides a technical solution: a cutting tool for high-speed cutting, including a tool holder 1, a mounting groove 11 is provided on one side of the tool holder 1, a docking hole 12 is provided on one side of the mounting groove 11, a cutting head 13 is detachably installed in the mounting groove 11, a stop block 14 is fixedly installed in the middle of one end of the cutting head 13, and an anti-loosening mechanism is installed on one side inside the tool holder 1.

[0025] The anti-loosening mechanism includes a piston groove 2 opened in the middle of one side of the tool holder 1, a piston block 21 movably installed in the mounting groove 11, a limiting groove 22 connected and installed at the other end of the piston groove 2, a limiting block 23 slidably installed in the limiting groove 22, a support rod 24 fixedly installed between the piston block 21 and the limiting block 23, and a spring 25 sleeved on the outer wall of the support rod 24. The abutment block 14 corresponds to the piston block 21, the piston groove 2 is connected to the mounting groove 11, and the two sides of the spring 25 are fixedly installed to the inner wall of the piston groove 2 and the side wall of the piston block 21, respectively.

[0026] When the cutter head 13 is installed on the tool holder 1, the abutment block 14 on one side of the cutter head 13 will engage with the piston groove 2 on the tool holder 1. Since the piston block 21 in the piston groove 2 is pushed out by the spring 25, when the operator installs the cutter head 13 on the tool holder 1, he needs to use the abutment block 14 to push the piston block 21 into the piston groove 2, so that the abutment block 14 on the cutter head 13 is engaged in the piston groove 2, which further improves the stability of the installation of the cutter head 13. After the cutter head 13 is installed, with the support force of the spring 25 sleeved on the outer wall of the support rod 24, the cutter head 13 can be continuously squeezed, which effectively ensures that the cutter head 13 will not fall off by the squeezing force of the spring 25 if it is not firmly fixed, thus achieving a good anti-fall-off effect.

[0027] In this technical solution, a pressure sensor 3 is fixedly installed at one end of the inner side of the limiting groove 22. The pressure sensor 3 corresponds to the limiting block 23 and can detect whether the cutter head 13 is installed in place. A groove 31 is opened in the middle of one end of the side wall of the cutter holder 1. An indicator light 32 is fixedly installed on one side inside the groove 31. The indicator light 32 is connected to the pressure sensor 3 through the first wire and can prompt the operator.

[0028] After the cutter head 13 is installed, it will press the piston block 21. Since the piston block 21 and the limit block 23 are fixedly installed with the support rod 24, the limit block 23 moves down synchronously and presses the pressure sensor 3. The pressure sensor 3 under pressure can send a signal to the control processor and turn on the indicator light 32. Conversely, if the indicator light 32 does not light up, it means that the cutter head 13 is not installed in place.

[0029] In this technical solution, a mounting hole 35 is provided on one side of the cutter head 13. The mounting hole 35 corresponds to the docking hole 12, so that the cutter head 13 can be mounted on the cutter holder 1.

[0030] By fitting the cutting head 13 into the mounting groove 11 and aligning the mounting hole 35 on the cutting head 13 with the mating hole 12 on the tool holder 1, and then installing the fasteners in the corresponding mounting holes 35 and mating holes 12, the cutting head 13 is firmly fixed on the tool holder 1.

[0031] In this technical solution, a charging port 33 is fixedly installed on the other side of the groove 31. The charging port 33 is connected to a rechargeable battery 34 through a second wire. The rechargeable battery 34 is connected to the pressure sensor 3 through a third wire, which can supply power to the pressure sensor 3 and the indicator light 32.

[0032] The rechargeable battery 34 inside the tool holder 1 can be charged through the charging port 33 in the groove 31, ensuring that the rechargeable battery 34 can continuously supply power to the pressure sensor 3 and the indicator light 32 to detect whether the tool head 13 is installed.

[0033] In use, first, the cutter head 13 is fitted into the mounting groove 11, and the mounting hole 35 on the cutter head 13 is aligned with the mating hole 12 on the tool holder 1. Then, the corresponding mounting holes 35 and mating holes 12 are fitted with fasteners to firmly fix the cutter head 13 onto the tool holder 1. At the same time, when the cutter head 13 is installed on the tool holder 1, the abutment block 14 on one side of the cutter head 13 will engage with the piston groove 2 on the tool holder 1. Since the piston block 21 in the piston groove 2 is pushed out by the spring 25, when the operator installs the cutter head 13 on the tool holder 1, the abutment block 14 needs to be pressed into the piston groove 2 by the abutment block 14, so that the abutment block 14 on the cutter head 13 is engaged in the piston groove 2, further improving the stability of the cutter head 13 installation. After the cutter head 13 is installed, it cooperates with the support rod 24. The supporting force of the wall sleeve spring 25 can continuously compress the cutter head 13, effectively ensuring that the cutter head 13 will not fall off due to the compressive force of the spring 25 if it is not firmly fixed, thus achieving a good anti-fall-off effect. At the same time, a pressure sensor 3 is fixedly installed on one end of the inner side of the limiting groove 22, and the pressure sensor 3 is connected to the indicator light 32 through the first wire. When the cutter head 13 is installed, the cutter head 13 will compress the piston block 21. Since the piston block 21 and the limiting block 23 are fixedly installed with a support rod 24, the limiting block 23 moves down synchronously and compresses the pressure sensor 3. The pressure sensor 3 under pressure can send a signal to the control processor and turn on the indicator light 32. Conversely, if the indicator light 32 does not light up, it means that the cutter head 13 is not installed in place.
