Description
TECHNICAL FIELD
[0001] The utility model relates to numerical control cutter installation technical field, especially a tooling of protection cutter dismounting. BACKGROUND
[0002] In the machine tool dismounting process, when the cutter needs to be disassembled and replaced, the cutter body is generally clamped by a lock seat, and the operator can separate the cutter chuck and the cutter handle to replace the chuck.
[0003] According to the dismounting structure, the cutter is divided into two kinds of keyways and non-keyways. The cutter with keyway can be fixed to the workbench through the fixed seat with a boss, and then dismounted by using a wrench. If the cutter without keyway is directly screwed by two hands with a wrench on the workbench, the chuck is easy to fly, so the worker uses two wrenches to change the cutter in the equipment when replacing the cutter. Because the worker uses two hands to force each other, under the action of inertia, the wrench often slips off and hits the cutter or the screw nut loosens and the cutter falls off and damages the cutting edge during the tightening and loosening process of the screw nut, so the worker's operation is extremely inconvenient, and the processing efficiency is reduced. When dismounting the cutter chuck, unstable clamping can easily cause damage to the cutter body, shortening the service life of the cutter.
[0004] At present, the traditional lock seat structure often uses screws or bolts to press the cutter body to complete the clamping of the cutter handle, and then uses a wrench to unscrew the chuck. Although the lock seat increases the constraint of the cutter, the use of screws or bolts to achieve clamping still needs the help of a wrench or screwdriver, and cannot be achieved by hand. And because the local pressure is large, the pressing end of the screw or bolt often leaves a pressure mark on the cutter handle, which causes wear in the short term, reduces the smoothness of the cutter handle surface, and forms a depression in the long term, thereby posing a risk of damaging the dynamic balance of the cutter handle. In addition, a lock seat of one type can only be used for dismounting and replacing one type of cutter body, and multiple corresponding types of lock seats need to be purchased for locking the cutter, increasing the cost.

[0035] Example 1
[0036] As Figure 1The tool shown is a tool for protecting the disassembly of a tool, comprising a locking tool seat 1 and a handle screw 2. The locking tool seat 1 is provided with a through hole 5, and an annular clamping method is adopted for clamping the tool, so that the locking tool seat 1 can increase the contact surface with the chuck 8 and adapt to the disassembly requirements of components of different sizes, and is applicable to tools with keyways, without keyways or non-standard tools. The locking tool seat 1 is provided with a gap 3 on one side along the plane where the axis of the through hole 5 is located, and the gap 3 is connected to the through hole 5. The handle screw 2 includes a handle portion and a screw portion, and the two are fixedly connected. The handle screw 2 is connected to the screw hole 6, specifically, the handle screw 2 is threadedly connected to the portion extending downward from the screw hole 6. When in use, the gap 3 is compressed, the through hole 5 is slightly deformed, and then the tool handle 9 is locked. Through the combination of the locking tool seat 1 and the handle screw 2, a barehanded and safe fixing method is provided for the disassembly of the tool, which effectively prevents the tool from being damaged or injuring people during the disassembly process.
[0037] like Figure 2 As shown, the locking knife holder 1 has a screw hole 6 extending vertically and perpendicularly to the slit 3 on one side, for connecting the handle screw 2. The upward extension of the screw hole 6 passes through the locking knife holder 1. The thread is M6x1-6H, which accommodates the 0.5mm clearance between the through hole 5 and the tool. This reduces the number of turns of the handle screw 2, saving time and effort. Because the handle is 50mm long and the wrist strength of an adult is approximately 60-120N, the tightening torque provided is greater than the 3.5N·m required by the M6 thread.
[0038] In this embodiment, the cross-section of the knife lock seat 1 is T-shaped, with an upper edge width of 86 mm and a lower edge width of 145 mm. The height of the upper and lower edges is 80 mm. The thickness of the knife lock seat 1 is 25 mm. The through hole 5 and the screw hole 6 are arranged in the middle leg of the T-shape, and the through hole 5 is 9.99 mm away from the upper edge. The axis of the through hole 5 is on the center line of the cross-section of the knife lock seat 1, which is convenient for maintaining clamping balance and stability and preventing uneven force; the screw hole 6 is 12 mm away from one end of the upper edge; the fixing holes 4 are symmetrically arranged on the two side legs of the T-shape, 12.5 mm away from one end of the lower edge. The part where the middle leg connects the two side legs is provided with a fillet with a radius of 6 mm to facilitate clamping and stress dispersion. The T-shaped design of the knife lock seat 1 makes the structure of the tooling more stable and compact, saves materials, and improves the overall mechanical stability and practicality of the tooling. The through-hole 5 has a diameter of 46 mm, with a tolerance of 0.1 to 0.2 mm, facilitating tool insertion and removal. The tool handle 9 has an outer diameter of 46 mm, with a tolerance of 0 to -0.2 mm. To accommodate different tool outer diameters, a metal ring 10, in the form of a C-ring or similar structure, such as a brass bushing, can be used to compensate for size differences and provide a secure grip for tools of varying sizes. The screw hole 6 has a diameter of 6.4 mm and a depth of 47 mm. The legs are 25 mm high.
[0039] likeFigure 3 As shown, the tool also includes a spacer 7, and the screw portion passes through the hole set in the spacer 7 and the screw hole 6 in sequence. The spacer 7 is convenient for holding the handle and provides upper space for rotation operation. The spacer 7 can also be lubricated to reduce the resistance of manual rotation.
[0040] like Figure 4 As shown, two fixing holes 4 are symmetrically provided at the lower part of the locking knife seat 1. The fixing holes 4 are through holes with a diameter of 8 mm and a tolerance range of 0 to 0.1 mm. Threads are provided inside for fixing the tooling to the workbench.
[0041] The locking knife seat 1 is made of 6061 aluminum alloy, which is softer than beryllium bronze and stainless steel, and has good resilience when deformed by 0.1 to 0.2 mm. At the same time, it can ensure that the locking knife seat 1 is not easily damaged or deformed during long-term use, thereby improving the durability and reliability of the tooling.
[0042] While the above embodiment employs a transverse arrangement of the through-holes 5 on the locking blade holder 1, the present invention can also employ a longitudinal arrangement of the through-holes 5, thereby changing the plane of manual rotation. These designs not only improve work efficiency but also reduce the difficulty and cost of disassembly, thereby enhancing the safety of the tool and personnel, reducing the difficulty of disassembly work, and improving stability and efficiency.
[0043] The specific usage method includes the following steps:
[0044] First, fix the locking knife seat 1 to the workbench with screws passing through the fixing holes 4.
[0045] The aperture of the locking knife seat 1 and the outer diameter of the knife handle 9 are clearance-matched. When in use, the knife is placed in the through hole 5, and the screw handle 2 is turned to tighten or loosen the knife.
[0046] When disassembling, use an open-end wrench, put it on the flattened part of the shank 9 and twist it, then the chuck 8 can be removed for replacement.
[0047] The above embodiment is only one of the implementation methods that can realize the technical solution of the present utility model. The scope of protection claimed by the present utility model is not limited only to the embodiment, but also includes any changes, replacements and other implementation methods that can be easily thought of by any person skilled in the art within the technical scope disclosed by the present utility model. Although the embodiments of the present utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
