Description

Technical Field

[0001] This utility model relates to the field of power tool disassembly technology, specifically to an axial power tool holder disassembly device for CNC machine tools. Background Technology

[0002] A powered tool holder is a tool holder mounted on a powered tool turret and driven by a servo motor. It is a connecting device between a small CNC milling and turning machine tool and a rotary cutting tool. It clamps the cutting tool and transmits the machine tool's power to the rotary cutting tool. The powered tool holder is a precision mechanical transmission device. When disassembling the cutting tool, the power gear must not rotate with the cutting tool.

[0003] Currently, the common method for installing rotating cutting tools is to clamp the tool holder in a bench vise, requiring two technicians to operate together. One person holds the tool and controls its clamping height, while the other uses an open-end wrench in their left hand to hold the tool holder's anti-rotation nut, and simultaneously uses a hook wrench in their right hand to rotate and tighten the clamping nut. This method requires two people to complete the disassembly. To facilitate disassembly, a tool disassembly device for an axial power tool holder of a CNC machine tool, as disclosed in announcement number "CN209919783U", is provided. This device is equipped with jaws that restrict the rotation of the tool holder by fixing a fixing block, making it convenient for a single person to disassemble.

[0004] However, during use, the operator needs to tighten the fastening bolts to restrict the jaws. After disassembly, tools are needed to loosen the fastening bolts to allow the jaws to open the nuts, which affects the overall efficiency. This is a tool disassembly device for an axial power tool holder of a CNC machine tool. Utility Model Content

[0005] The purpose of this utility model is to provide an axial power tool holder tool disassembly device for CNC machine tools to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an axial power tool holder tool disassembly device for a CNC machine tool, comprising a base, a limiting and fixing device provided on the top of the base, a control device for limiting the limiting and fixing device provided on the top of the base, and a transverse sliding groove and a vertical sliding groove provided on the top of the base.

[0007] The restraining and fixing device includes:

[0008] A retaining clamp is used to restrict the clamping nut of the cutting tool;

[0009] The contact plate is used to limit the movement of the fixing clamp.

[0010] Preferably, the fixing clamp consists of two sets of clamping plates, a support spring, and a shaft. Both sets of clamping plates are hinged to the shaft, which is fixed to the top of the base. A support spring is fixed between the two sets of clamping plates. When the clamping plates are not restricted, the two sets of clamping plates are in an open state under the action of the support spring, which makes it convenient for the operator to control the clamping plates to fix the clamping nut of the tool.

[0011] Preferably, the abutment plate is slidably installed on the inner side of the vertical slide groove. A connecting spring is fixed to the side of the abutment plate away from the fixing clamp. The end of the connecting spring away from the abutment plate is fixed to the inner side of the vertical slide groove. Two sets of abutment plates and connecting springs are provided. The two sets of abutment plates and connecting springs are symmetrically arranged. By pushing the two sets of abutment plates closer to each other, the two sets of clamping plates can be pushed to close and clamp the clamping nut of the tool. The vertically moving abutment plate can effectively restrict the clamping plates, making the clamping plates stable during use and preventing the clamping plates from loosening, which would affect the disassembly of the tool.

[0012] Preferably, the control device includes a limiting tooth plate, which is slidably mounted in a transverse groove on the top of the base. A mating tooth is fixed to the side of the abutment plate near the limiting tooth plate. A fixing rod is fixed to the top of the base, passing through and slidably connected to the control rod. A return spring is fixed to the bottom of the control rod, with the end of the return spring away from the control rod fixed to the top of the base. A support rod is hinged to the bottom of the control rod, with the end of the support rod away from the control rod hinged to the top of the limiting tooth plate. The teeth of the limiting tooth plate and the mating tooth are in opposite directions. Through the interlocking of the limiting tooth plate and the mating tooth, when the abutment plate is pushed towards the side near the fixing clamp, the inclined surface of the mating tooth on the abutment plate abuts against the inclined surface of the limiting tooth plate, pushing the limiting tooth plate towards the side near the fixing clamp. When the contact plate moves away from the clamping plate, it is released. As the contact plate moves away from the clamping plate under the action of the connecting spring, the vertical surfaces of the teeth of the mating teeth and the vertical surfaces of the teeth of the limiting teeth abut against each other, restricting the contact plate and achieving unidirectional limiting of the contact plate to ensure its stability. After use, the operator only needs to push the control lever downwards, which will control the support rod to push the limiting teeth to the side away from the contact plate, thereby disengaging from the mating teeth and releasing the restriction on the contact plate. The contact plate can then move away from the clamping plate under the action of the connecting spring, no longer abutting against the clamping plate. The two sets of clamping plates can then open under the action of the support spring, releasing the fixed state. The operation is convenient and effectively improves the overall work efficiency. It can be operated by a single person.

[0013] Preferably, each of the two sets of clamping plates has a movable groove on one side close to each other. An embedded block is slidably installed on the inner side of the movable groove, and a compression spring is fixed on the inner side of the movable groove. The end of the compression spring away from the movable groove is connected to the embedded block. When disassembling tools for different types of axial power tool holders (e.g., BMT power tool holder, WTO power tool holder), since the clamping nut of the tool holder is round and has a groove on its surface, the normal locking method for hexagonal nuts cannot be properly fixed. The embedded block can pop out under the action of the compression spring and get stuck in the groove on the surface of the round clamping nut to restrict it. When locking the normal hexagonal nut, the embedded block is pushed into the movable groove by the hexagonal nut, which does not affect the normal locking of the clamping plate for the hexagonal nut. It has a wider range of applications, requires less operation, and is convenient to use.

[0014] Compared with the prior art, this utility model provides an axial power tool holder tool disassembly device for CNC machine tools, which has the following beneficial effects:

[0015] 1. The axial power tool holder tool disassembly device of this CNC machine tool, through the setting of a limiting and fixing device and a control device, only needs to control the two sets of contact plates to move closer to each other during fixing, so that the two sets of clamping plates can be controlled to restrict the clamping nut. After disassembly, only the control rod needs to be pushed down to control the two sets of clamping plates to be released, thereby releasing the fixing state. It can be operated by a single person, which is convenient and effectively improves the overall work efficiency.

[0016] 2. The axial power tool holder tool disassembly device of this CNC machine tool, through the setting of the embedded block and the compression spring, can disassemble the tools of different power tool holders, and has a wide range of applications. Attached Figure Description

[0024] like Figures 1-6 As shown, this utility model provides a technical solution: an axial power tool holder tool disassembly device for a CNC machine tool, including a base 1, a limiting and fixing device 2 provided on the top of the base 1, a control device 3 for limiting the limiting and fixing device 2 provided on the top of the base 1, a horizontal slide groove 4 and a vertical slide groove 5 provided on the top of the base 1, and the limiting and fixing device 2 includes: a fixing clamp 21, a contact plate 22, and a connecting spring 23.

[0025] The fixing clamp 21 consists of two sets of clamping plates 211, a support spring 212, and a shaft 213. Both sets of clamping plates 211 are hinged to the shaft 213, which is fixed to the top of the base 1. The support spring 212 is fixed between the two sets of clamping plates 211. When the clamping plates 211 are not restricted, the two sets of clamping plates 211 are in an open state under the action of the support spring 212, which makes it convenient for the staff to control the clamping plates 211 to fix the clamping nut of the tool.

[0026] The contact plate 22 is slidably installed on the inner side of the vertical slide groove 5. A connecting spring 23 is fixed on the side of the contact plate 22 away from the fixing clamp 21. The end of the connecting spring 23 away from the contact plate 22 is fixed on the inner side of the vertical slide groove 5. There are two sets of contact plates 22 and connecting springs 23. The two sets of contact plates 22 and connecting springs 23 are symmetrically arranged. By pushing the two sets of contact plates 22 closer to each other, the two sets of clamping plates 211 can be pushed to close and clamp the clamping nut of the tool. The vertically moving contact plate 22 can effectively resist and restrict the clamping plate 211, making the clamping plate 211 stable during use and preventing the clamping plate 211 from loosening, which would affect the disassembly of the tool.

[0027] The control device 3 includes a limiting tooth plate 31, which is slidably mounted in a transverse groove 4 on the top of the base 1. A mating tooth 32 is fixed to the side of the contact plate 22 near the limiting tooth plate 31. A fixing rod 33 is fixed to the top of the base 1, passing through and slidably connected to the control rod 34. A return spring 35 is fixed to the bottom of the control rod 34, with one end of the return spring 35 away from the control rod 34 fixed to the top of the base 1. A support rod 36 is hinged to the bottom of the control rod 34, with one end of the support rod 36 away from the control rod 34 hinged to the top of the limiting tooth plate 31. The teeth of the limiting tooth plate 31 and the mating tooth 32 are in opposite directions. The limiting tooth plate 31 and the mating tooth 32 engage with each other. When the contact plate 22 is pushed towards the side closer to the fixing clamp 21, the inclined surface of the mating tooth 32 on the contact plate 22 abuts against the inclined surface of the teeth of the limiting tooth plate 31, pushing the limiting tooth plate 31 away from the contact plate 21. When the contact plate 22 is released and moves away from the fixed clamp 21 under the action of the connecting spring 23, the vertical surface of the teeth of the mating tooth 32 abuts against the vertical surface of the teeth of the limiting tooth plate 31, thus restricting the contact plate 22 and achieving unidirectional limiting of the contact plate 22 to ensure its stability. After use, the operator only needs to push the control rod 34 down, which will control the support rod 36 to push the limiting tooth plate 31 away from the contact plate 22, thereby disengaging from the mating tooth 32 and releasing the restriction on the contact plate 22. The contact plate 22 can then move away from the fixed clamp 21 under the action of the connecting spring 23 and no longer abut against the clamp plate 211. The two sets of clamp plates 211 can then open under the action of the supporting spring 212, thus releasing the fixed state. The operation is convenient and effectively improves the overall work efficiency. It can be operated by a single person.

[0028] Both sets of clamping plates 211 have a movable groove 6 on their adjacent sides. An embedded block 7 is slidably installed on the inner side of the movable groove 6. A compression spring 8 is fixed on the inner side of the movable groove 6. The end of the compression spring 8 away from the movable groove 6 is connected to the embedded block 7. When disassembling tools for different types of axial power tool holders (such as BMT power tool holders and WTO power tool holders), since the clamping nut of the tool holder is round and has a groove on its surface, the normal locking method for hexagonal nuts cannot be properly fixed. The embedded block 7 can pop out under the action of the compression spring 8 and get stuck in the groove on the surface of the round clamping nut to restrict it. When locking the normal hexagonal nut, the embedded block 7 is pushed into the movable groove 6 by the hexagonal nut, which will not affect the normal locking of the clamping plate 211 for the hexagonal nut. It has a wider range of applications and requires less operation, making it convenient to use.

[0029] In this utility model, during use, the power knife holder passes through the bottom of the base 1 and the base 1 is fixed. After the base 1 is fixed, the operator manually pushes the abutment plate 22 to move it closer to the fixing clamp 21. During this process, the clamp plate 211 fixes the clamping nut. The operator uses a wrench to disassemble the knife. As it rotates, the clamp plate 211 and the clamping nut are fully engaged. Then, the abutment plate 22 is pushed to apply pressure to the clamp plate 211 again to ensure the stability of the clamp plate 211. At this time, the disassembly operation can continue.

[0030] After disassembly, the operator only needs to push the control lever 34 downwards. The control lever 34 will control the support rod 36 to push the limiting tooth plate 31 to the side away from the contact plate 22, thereby disengaging it from the engaging tooth 32 and releasing the restriction on the contact plate 22. The contact plate 22 can then move away from the fixing clamp 21 under the action of the connecting spring 23, no longer resisting the clamp 211. The two sets of clamps 211 can then open under the action of the supporting spring 212, releasing the fixed state. The operation is convenient and effectively improves the overall work efficiency. It can be operated by a single person.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
