Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically to an integrated composite machining tool set. Background Technology

[0002] CNC cutting tools are tools used for cutting processes in mechanical manufacturing, also known as cutting tools. In a broad sense, cutting tools include both cutting tools and grinding wheels; furthermore, "CNC cutting tools" include not only cutting inserts but also accessories such as tool holders and tool shanks. With the rapid development of the manufacturing industry, the requirements for processing efficiency and precision are becoming increasingly stringent. Traditional cutting tools often have single functions and require frequent changes, leading to longer processing times and increased costs. The emergence of integrated composite machining tool sets is precisely to solve this problem, enabling the completion of multiple machining operations in a single setup by integrating the functions of multiple cutting tools.

[0003] A search revealed a utility model patent with Chinese patent publication number CN109773252A, which discloses an integrated milling cutter, including a cutting part, a tool holder, a base, a positioning groove, and a mounting hole. The cutting part includes a first cutting body and a second cutting body, which are stacked along the axial direction of the cutting part. A plurality of first cutting grooves are provided on the outer surface of the first cutting body, and the first cutting grooves are parallel to each other. A plurality of second cutting grooves are also provided on the outer surface of the second cutting body, and the second cutting grooves are parallel to each other. The cutting part is integrally formed on the front end of the tool holder, and the base is integrally formed on the rear end of the tool holder. A first clamping surface and a second clamping surface are provided on the base. The first clamping surface is located at the rear end of the base, and the second clamping surface is located at the rear end of the first clamping surface. The positioning groove is provided on both sides of the second clamping surface, and the mounting hole is located at the center of the lower surface of the base.

[0004] As with the tools mentioned above, the end mill connector will gradually wear down over time, causing an increase in the clearance between it and the milling head, which will result in wobbling. At this time, the finished product may have slight errors, leaving room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated composite machining tool set to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated composite machining tool holder, including a tool holder, with three equally spaced reinforcing components installed inside the tool holder. Each reinforcing component includes a receiving groove formed at the bottom of the outer circumference of the tool holder. A connecting ring is bolted to the inner wall of one end of the receiving groove. A horizontally arranged tension spring is fixedly connected to the outer wall of one end of the connecting ring. A mounting base is fixedly connected to one end of the tension spring. A stabilizing pin is slidably sleeved on the outside of the mounting base. The stabilizing pin and the mounting base are connected by bolts. A horizontally arranged clearance hole is formed inside the stabilizing pin.

[0007] When the tool enters the running state, a secondary connection operation is performed on the machine head. This operation can further enhance the overall structural stability of the tool, thereby effectively preventing the tool from shaking during subsequent use. During operation, the tool holder generates centrifugal force due to rapid rotation. As the centrifugal force increases, the tension spring begins to stretch under stress. The mounting base and stabilizing pin connected to the tension spring will move out of the receiving groove and then be inserted into the positioning groove set in the external machine head. If the tool holder tends to shake, the machine head can limit it through the stabilizing pin, effectively preventing the tool from shaking. If it is necessary to replace the stabilizing pin or tension spring, use a screwdriver to remove the bolts connecting the stabilizing pin and the mounting base. The stabilizing pin can then be disassembled. Then, pass the screwdriver through the screw hole in the middle of the mounting base and remove the bolts connecting the connecting ring and the tool holder again. The connecting ring can also be disassembled.

[0008] As a further preferred embodiment of this technical solution, a reamer is provided at one end of the bottom of the tool holder, and a milling cutter is provided at one end of the bottom of the reamer. The milling cutter at the bottom of the tool holder can perform milling on the external workpiece. If it is necessary to expand the external hole, the milling cutter is passed through the external hole, and then the reamer is moved to the working position. Through the cooperation of the reamer and the milling cutter, the hole expansion work can be performed quickly.

[0009] As a further preferred embodiment of this technical solution, two positioning slots are provided in the middle of the outer circumference of the tool holder, and the two positioning slots are symmetrically arranged. The tool holder is inserted into the machine head and then fixed in place by means of the positioning slots.

[0010] As a further preferred embodiment of this technical solution, the edge of the stabilizing pin near the outer end is provided with a rounded corner, which improves the fault tolerance rate of the insertion process when the stabilizing pin is inserted into the outer positioning hole due to the presence of the rounded corner, so that the structure can be used normally.

[0011] As a further preferred embodiment of this technical solution, the tool holder, the reamer and the end mill's base are made of lightweight titanium alloy material. This material has the effect of reducing tool inertia, thereby improving the dynamic response capability of the tool holder during high-speed machining.

[0012] As a further preferred embodiment of this technical solution, the front part of the cutting edge of the reamer and the milling cutter is made of ultra-hard nanocrystalline tungsten carbide material. This material has the characteristics of high hardness, low coefficient of friction, and reduced cutting force, which can extend the tool life. The rear part of the cutting edge is made of high-toughness high-speed steel, which can absorb the vibration generated during operation, prevent the tool from breaking, and improve machining stability.

[0013] As a further preferred embodiment of this technical solution, the chip removal grooves of the reamer and milling cutter are coated with a polycrystalline diamond coating, which gives the chip removal grooves the characteristics of low friction and high thermal conductivity, thereby accelerating chip removal and preventing the phenomenon of sticking to the cutter.

[0014] This utility model provides an integrated composite machining tool set, which has the following beneficial effects:

[0015] This invention, by setting up a reinforcement component, performs a secondary connection operation on the machine head when the tool enters the running state. This operation can further enhance the overall structural stability of the tool, thereby effectively preventing the tool from shaking during subsequent use. During operation, the tool holder generates centrifugal force due to rapid rotation. As the centrifugal force increases, the tension spring begins to stretch under stress. The mounting base and stabilizing pin connected to the tension spring will move out of the receiving groove and then be inserted into the positioning groove set in the external machine head. If the tool holder tends to shake, the machine head can restrict it through the stabilizing pin, effectively preventing the tool from shaking. If it is necessary to replace the stabilizing pin or tension spring, use a screwdriver to remove the bolt connecting the stabilizing pin and the mounting base. The stabilizing pin can then be disassembled. Then, pass the screwdriver through the screw hole in the middle of the mounting base and remove the bolt connecting the connecting ring and the tool holder again. The connecting ring can also be disassembled. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 3 and Figure 4 As shown in this embodiment, an integrated composite machining tool kit includes a tool holder 1. Three equally spaced reinforcing components 5 are installed inside the tool holder 1. Each reinforcing component 5 includes a receiving groove 501 formed at the bottom of the outer circumference of the tool holder 1. A connecting ring 502 is bolted to the inner wall of one end of the receiving groove 501. A horizontally arranged tension spring 503 is fixedly connected to the outer wall of one end of the connecting ring 502. A mounting base 504 is fixedly connected to one end of the tension spring 503. A stabilizing pin 505 is slidably sleeved on the outside of the mounting base 504. The stabilizing pin 505 and the mounting base 504 are connected by bolts. A horizontally arranged clearance hole 506 is formed inside the stabilizing pin 505.

[0023] During operation, the tool holder 1 generates centrifugal force due to rapid rotation. As the centrifugal force increases, the tension spring 503 begins to stretch under stress. The mounting base 504 and the stabilizing pin 505 connected to the tension spring 503 will move out of the receiving groove 501 and then be inserted into the positioning groove set in the external machine head. If the tool holder 1 tends to wobble, the machine head can limit it through the stabilizing pin 505, effectively preventing the tool from wobbling. If it is necessary to replace the stabilizing pin 505 or the tension spring 503, use a screwdriver to remove the bolt connecting the stabilizing pin 505 and the mounting base 504. The stabilizing pin 505 can then be disassembled. Then, pass the screwdriver through the screw hole in the middle of the mounting base 504 and remove the bolt connecting the connecting ring 502 to the tool holder 1. The connecting ring 502 can also be disassembled.

[0024] like Figure 1 and Figure 2 As shown, a reamer 3 is provided at one end of the bottom of the tool holder 1, and a milling cutter 4 is provided at one end of the bottom of the reamer 3. The milling cutter 4 at the bottom of the tool holder can perform milling on the external workpiece. If it is necessary to expand the external hole, the milling cutter 4 is passed through the external hole, and then the reamer 3 is moved to the working position. Through the cooperation of the reamer 3 and the milling cutter 4, the hole expansion work can be performed quickly.

[0025] like Figure 1 and Figure 2 As shown, two positioning slots 2 are provided in the middle of the outer circumference of the tool holder 1, and the two positioning slots 2 are symmetrically arranged. The tool holder 1 is inserted into the machine head and then fixed in place by the positioning slots 2.

[0026] like Figure 3 As shown, the edge of the stabilizing pin 505 near the outer end is rounded, which improves the fault tolerance rate of the insertion process when the stabilizing pin 505 is inserted into the outer positioning hole, so that the structure can be used normally.

[0027] like Figure 1 and Figure 2 As shown, the base of the tool holder 1, the reamer 3, and the end mill 4 are made of lightweight titanium alloy material. This material has the effect of reducing tool inertia, thereby improving the dynamic response capability of the tool holder during high-speed machining.

[0028] like Figure 1 and Figure 2 As shown, the front part of the cutting edge of the reamer 3 and the end mill 4 is made of ultra-hard nanocrystalline tungsten carbide material. This material has the characteristics of high hardness, low coefficient of friction, and reduced cutting force, which can extend the tool life. The rear part of the cutting edge is made of high-toughness high-speed steel, which can absorb the vibration generated during operation, prevent the insert from breaking, and improve machining stability.

[0029] like Figure 1 and Figure 2 As shown, the chip grooves of the reamer 3 and the end mill 4 are coated with a polycrystalline diamond coating, which gives the chip grooves low friction and high thermal conductivity, accelerating chip removal and preventing chip sticking.

[0030] This utility model provides an integrated composite machining tool sleeve, the specific working principle of which is as follows:

[0031] When the device is in operation, the tool holder 1 is inserted into the external machine head, and then fixed in place by the positioning slot 2. During operation, the tool holder 1 generates centrifugal force due to rapid rotation. As the centrifugal force increases, the tension spring 503 begins to extend under stress. The mounting base 504 and the stabilizing pin 505 connected to the tension spring 503 will move out of the receiving slot 501 and then be inserted into the positioning slot provided in the external machine head. If the tool holder 1 tends to wobble, the machine head can limit it through the stabilizing pin 505, effectively preventing the tool from wobbling. If the stabilizing pin 505 needs to be replaced... 5 or tension spring 503, use a screwdriver to remove the bolts connecting the stabilizing pin 505 and the mounting base 504, then the stabilizing pin 505 can be disassembled. Then, pass the screwdriver through the screw hole in the middle of the mounting base 504 and remove the bolts connecting the connecting ring 502 and the tool holder 1 again, so the connecting ring 502 can also be disassembled. The milling cutter 4 at the bottom of the tool holder can perform milling on the external workpiece. If it is necessary to expand the external hole, pass the milling cutter 4 through the external hole, and then move the reamer 3 to the working position. Through the cooperation of the reamer 3 and the milling cutter 4, the hole expansion work can be performed quickly.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
