Description

Technical Field

[0001] This utility model relates to the field of machine tool cutting tool technology, and specifically to a tool mounting and dismounting auxiliary device. Background Technology

[0002] As core equipment in modern manufacturing, CNC machine tools require frequent and critical tool clamping and disassembly. Tools consist of two parts: the tool holder and the cutting tool (such as the drill bit). The tool holder is fixed to the spindle and generally does not need to be disassembled unless for basic maintenance or repair; only the cutting tool needs to be replaced. However, with the continuous optimization of CNC machine tools, modern CNC machine tools have tool magazines that enable automatic tool changing, eliminating the hassle of manual tool changing. The tool magazine can carry multiple pre-assembled, complete tools. This necessitates manual installation of the required cutting tool on the tool holder before machining. However, since tool holders do not require frequent disassembly and assembly, the industry is unwilling to invest in developing auxiliary devices specifically for disassembling tool holders. Most tool holder disassembly and assembly still relies on manual labor, typically requiring one hand to hold one end of the tool holder while turning the other. Disassembly is quite cumbersome, and some manufacturers have designed a fixing seat to improve ease of disassembly. When removing the tool, the tool holder can be placed on the fixing seat, making disassembly and assembly easier. The fixing seat has a cylindrical structure. When using it, one end of the tool holder needs to be inserted into the cylindrical tube, and the protrusion on the upper side of the cylindrical tube and the notch of the tool holder are used to lock it in place, thus fixing the tool holder itself. However, this fixing seat only serves to fix the tool holder and make it face upwards. In addition to the end where the cutting tool is installed, which is used more frequently, the other end of the tool holder also has a pull pin, tapered shank, and other structures. These structures also require regular maintenance and repair. However, the current fixing seat can only operate on one end of the tool holder. When it is necessary to operate on the other end of the tool holder, the tool holder must be flipped first. However, after the tool holder is flipped, the limiting groove can no longer be locked in place with the fixing seat. Currently, the end where the cutting tool is installed can only be fixed manually. Utility Model Content

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0020] As shown in the figure, this utility model discloses a tool mounting and dismounting auxiliary device, including a tool holder body 1. The upper side of the tool holder body 1 is provided with an arc portion 10, which corresponds to the circular ring portion in the middle of the tool holder seat. The central angle of the arc portion 10 is preferably 180 degrees. The tool holder body 1 has an abutment plate 20 at the front end of the arc portion 10 along the axial direction and a baffle 30 at the rear end. The baffle 30 is pushed closer to or away from the abutment plate 20 by a pushing mechanism 31. The side of the abutment plate 20 facing the baffle 30 is symmetrically provided with a limiting block 201 that cooperates with the limiting groove of the tool holder seat. Both the baffle 30 and the abutment plate 20 are U-shaped.

[0021] It also includes a working surface 2. The tool holder body 1 is fixed on the working surface 2. The tool holder is placed horizontally on the tool holder body 1. The central annular portion 70 is placed on the arc portion 10, so that the abutting plate 20 abuts against one side of the annular portion 70. The central annular portion 70 of the tool holder has a limiting groove 700 on one side. The limiting groove 700 is a structure of the existing tool holder and is used to cooperate with the spindle of the CNC machine tool. The abutting plate 20 is provided with a limiting block 201, which is inserted into the limiting groove 700 to prevent the tool holder from rotating. At this time, the baffle 30 is pushed to the other side of the annular portion 70 by the pushing mechanism 31, thereby realizing the fixation of the tool holder. This is a basic fixing method. Specifically, the limiting block 201 and the limiting groove 700 on the tool holder cooperate to prevent the tool holder from rotating. The tool holder rotates on the tool holder body 1, so the limiting block 201 only needs to have a width corresponding to the width of the limiting groove 700. The height of the limiting block 201 is set to be less than the depth of the limiting groove 700, which is more conducive to the cooperation between the abutment plate 20 and the tool holder. In addition, the limiting block 201 and the limiting groove 700 can be separated, and the circular part 70 of the tool holder can be clamped and fixed by the abutment plate 20 and the baffle 30. For example, after the tool holder is placed on the arc part 10, the tool holder is rotated so that the limiting groove 700 is misaligned with the limiting block 201 of the abutment plate 20, and the circular part 70 of the tool holder is clamped and fixed by the abutment plate 20 and the baffle 30. Alternatively, the tool holder can be placed on the arc part 10 at the beginning, and the limiting groove 700 can face the side of the baffle 30 to avoid cooperation with the limiting block 201.

[0022] The present invention provides a tool assembly and disassembly auxiliary device, which provides an arc portion 10 on the tool holder body 1, so that the tool holder can lie horizontally on the arc portion 10, and both ends of the tool holder are located at both ends of the tool holder body 1. People can disassemble or assemble either end in a targeted manner. The abutment plate 20 and the baffle 30 are used to block the two ends of the central ring portion 70 of the tool holder, thereby restricting the tool holder and effectively assisting people in assembling and disassembling the tool holder.

[0023] In some embodiments, a slide rail 40 is provided on the working surface 2, the slide rail 40 is aligned with the axis of the tool holder body 1, and a slider 401 is slidably disposed on the slide rail 40. A baffle 30 is connected to the slider 401. Specifically, the bottom of the baffle 30 is provided with a base plate corresponding to the slider 401, the base plate has a through hole, and the slider 401 has a screw hole corresponding to the through hole. A screw is inserted through the through hole and threaded into the screw hole, meaning the baffle 30 can slide linearly along the axis of the arc portion 10. Mechanism 31 is installed inside the tool holder body 1, and the output end of the pushing mechanism 31 is fixedly connected to the baffle 30. Specifically, the fixed part of the pushing mechanism 31 is set inside the tool holder body 1 and is fixed by connecting with the working surface 2. The output end is fixedly connected to the slider 401 at the bottom of the baffle 30. The pushing mechanism 31 can be an electric telescopic rod, hydraulic rod, etc. The fixed part of the pushing mechanism 31 is installed inside the tool holder body 1. The pushing mechanism 31 pushes the baffle 30 to slide linearly along the slide rail 40, thereby abutting one side of the tool holder.

[0024] In some embodiments, the slide rail 40 is slidably provided with a center pin 50, which is aligned with the shaft core of the arc portion 10. This center pin 50 is primarily used to allow people to check whether the cutting tool on the tool holder is aligned with the center and properly installed. The specific installation structure is as follows: Figure 1 As shown, a slide rail 40 is provided at one end of the tool holder body 1. The baffle 30 and the center pin 50 are both provided on the slide rail 40. A slider 401 is also provided at the bottom of the center pin 50, and it is slidably connected to the slide rail 40 through the slider 401. During inspection, the center pin 50 can be pulled to the end near the tool holder to set the push mechanism 31 inside the tool holder body 1, making the working surface 2 more concise and better protecting the push mechanism 31.

[0025] In some embodiments, to facilitate operation of structures away from the cutting tool end of the tool holder, such as the assembly and disassembly of a pull pin, the annular portion 70 of the tool holder can be directly clamped and fixed using the abutment plate 20 and the baffle 30. Since the limiting block 201 is not engaged with the limiting groove 700 at this time, to ensure the stability of the tool holder and prevent its rotation, two clamping plates 60 are detachably provided on the arc portion 10. The two clamping plates 60 are located at both ends of the top of the arc portion 10. When only the abutment plate 20 and the baffle 30 are used to clamp and fix the annular portion 70 of the tool holder, after the tool holder is placed on the arc portion 10, rotating the tool holder causes the limiting groove 700 to engage with the abutment plate 20. The limiting block 201 of the connecting plate 20 is offset, and the circular part 70 of the tool holder is clamped and fixed by the abutting plate 20 and the baffle 30. Alternatively, the tool holder is initially placed on the arc part 10 with the limiting groove 700 facing the side of the baffle 30 to avoid engagement with the limiting block 201. This fixing method is preferably used for disassembling and assembling the other end of the tool holder structure. In this case, to prevent the tool holder from rotating between the abutting plate 20 and the baffle 30, a clamping plate 60 can be provided on the arc part 10. One clamping plate 60 is used in conjunction with the arc part 10 to clamp and fix the tool holder, or both clamping plates 60 are used together to clamp and fix the circular part 70 in conjunction with the arc part 10. Figure 1 As shown, both the clamping plate 60 and the tool holder body 1 have connecting holes. The clamping plate 60 is connected to the tool holder body 1 by screws. An anti-slip layer can also be provided on the inner side of the clamping plate 60 to increase friction with the ring part 70.
