Description

Technical Field

[0001] This utility model is a quick-connect structure for cutting tools, belonging to the field of milling cutter technology. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, the cutting teeth sequentially and intermittently remove the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces.

[0003] In the existing technology, when it is necessary to install a milling machine cutter head, the bottom of the milling machine hydraulic tool holder needs to be removed before the milling machine cutter head can be reassembled. This is inconvenient for replacing or installing the milling machine cutter head and increases working time. There is an urgent need for a quick-connect tool structure to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a quick-connect structure for cutting tools to solve the problems mentioned in the background. This utility model is highly practical. By using hydraulic oil to hold the milling machine cutter head in place, the milling machine cutter head can be securely installed inside the milling machine hydraulic tool holder. When it is necessary to remove the milling machine cutter head, the milling machine will draw away the hydraulic oil, allowing the user to quickly remove the milling machine cutter head and thus reducing disassembly and assembly time.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a quick-connect structure for a cutting tool, including a milling machine hydraulic tool holder, an oil reservoir at the lower end of the milling machine hydraulic tool holder, a milling machine cutter head slidably connected in the oil reservoir, a rectangular positioning block fixedly connected to the upper end of the milling machine cutter head, a positioning connector fixedly connected to the circumferential surface of the milling machine cutter head, two magnetic sleeves fixedly connected inside the milling machine hydraulic tool holder, and two oil inlet grooves opened inside the milling machine hydraulic tool holder.

[0006] Furthermore, the milling machine hydraulic tool holder has two sealing oil rings fixedly connected inside.

[0007] Furthermore, the positioning joint mates with the bottom of the milling machine hydraulic tool holder.

[0008] Furthermore, the milling cutter head is attracted and connected to the two magnetic sleeves.

[0009] Furthermore, a corrosion-resistant layer is provided on the surface of the oil inlet groove, the oil storage groove, and the middle section of the milling machine cutter head.

[0010] Furthermore, the two oil inlets are connected to the oil storage tank.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a quick-connect structure for cutting tools. Because it adds an oil inlet groove, a magnetic sleeve, a positioning connector, a rectangular positioning block, and an oil storage groove, our design improvements and actual use have shown that this device has a reasonable structure and good practicality. By using hydraulic oil to hold the milling machine cutter head structure, the milling machine cutter head can be firmly installed in the milling machine hydraulic tool holder. When it is necessary to remove the milling machine cutter head, the milling machine will draw away the hydraulic oil, which makes it convenient for users to quickly remove the milling machine cutter head, thereby reducing disassembly and assembly time.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-5This utility model provides a technical solution: a quick-connect structure for a cutting tool, including a milling machine hydraulic tool holder 1, an oil reservoir 5 at the lower end of the milling machine hydraulic tool holder 1, a milling machine cutter head 2 slidably connected in the oil reservoir 5, a rectangular positioning block 8 fixedly connected to the upper end of the milling machine cutter head 2, a positioning connector 7 fixedly connected to the circumferential surface of the milling machine cutter head 2, two magnetic sleeves 4 fixedly connected inside the milling machine hydraulic tool holder 1, and two oil inlet grooves 3 opened inside the milling machine hydraulic tool holder 1. This design solves the problem that in the original device, when it is necessary to install the milling machine cutter head 2, the bottom of the milling machine hydraulic tool holder 1 needs to be removed and then the milling machine cutter head 2 needs to be reassembled, which is not convenient for replacing or installing the milling machine cutter head 2 and increases working time.

[0021] As the first embodiment of this utility model: Two sealing oil rings 6 are fixedly connected inside the milling machine hydraulic tool holder 1. The sealing oil rings 6 installed inside the milling machine hydraulic tool holder 1 can increase the sealing performance of the connection between the milling machine cutter head 2 and the milling machine hydraulic tool holder 1, preventing hydraulic oil leakage from the oil reservoir 5. The positioning connector 7 cooperates with the bottom of the milling machine hydraulic tool holder 1, which can assist the rectangular positioning block 8 in positioning and connecting with the inside of the milling machine hydraulic tool holder 1, and at the same time can seal the connection between the milling machine hydraulic tool holder 1 and the milling machine cutter head 2, preventing hydraulic oil leakage. The milling machine cutter head 2 is attracted and connected to the two magnetic sleeves 4, which can install the milling machine cutter head 2 inside the milling machine hydraulic tool holder 1, and then fix it inside the milling machine hydraulic tool holder 1 by hydraulic oil. The oil inlet groove 3, the oil reservoir 5, and the middle section surface of the milling machine cutter head 2 are all provided with a corrosion-resistant layer to prevent the hydraulic oil from corroding the structure of the milling machine hydraulic tool holder 1 and the milling machine cutter head 2, and to increase the smoothness of the milling machine hydraulic tool holder 1 and the milling machine cutter head 2. Two oil inlets 3 are connected to the oil storage tank 5. The milling machine hydraulic tool holder 1 is fixedly installed on the milling machine by hydraulic oil. The hydraulic oil then flows into the oil storage tank 5 through the oil inlets 3, blocking the upper end of the milling machine cutter head 2, thereby fixing the milling machine cutter head 2 in the milling machine hydraulic tool holder 1.

[0022] As a second embodiment of this utility model: First, align the milling cutter head 2 with the oil reservoir 5 inside the milling machine hydraulic tool holder 1, and simultaneously align the positioning connector 7 with the bottom of the milling machine hydraulic tool holder 1. Then, place the milling cutter head 2 into the milling machine hydraulic tool holder 1. The magnetic sleeve 4 will attract the surface of the milling cutter head 2. After placing the milling machine hydraulic tool holder 1 at the tool holder mounting position on the milling machine, the milling machine will introduce hydraulic oil into the milling machine hydraulic tool holder 1. The hydraulic oil will fix the milling machine hydraulic tool holder 1 on the milling machine's rotating shaft. At the same time, the hydraulic oil will enter the oil reservoir 5 through the oil inlet groove 3. When the oil reservoir 5 is filled with hydraulic oil, it will fix the milling cutter head 2 inside the milling machine hydraulic tool holder 1. When replacing the milling cutter head 2, the hydraulic oil can be pumped out through the milling machine. After removing the milling machine hydraulic tool holder 1, the milling cutter head 2 can be pulled out to replace the milling cutter.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
