Description

Technical Field

[0001] This utility model belongs to the field of cutting tool technology, specifically relating to a combined T-groove tool quick-change tool body structure. Background Technology

[0002] CNC cutting tools are high-precision, high-efficiency cutting tools widely used in modern manufacturing. They are not only widely used in metal processing, 3D printing, sheet metal processing, plastics processing, and woodworking, but also play a vital role in aerospace, automotive manufacturing, mold making, rail transportation, energy, and petrochemical industries. CNC cutting tools come in a variety of structures and classifications. Based on their structure, they can be divided into integral, welded, and mechanically clamped types. Mechanically clamped types are widely used due to their high durability and ease of replacement. The performance characteristics of CNC cutting tools include high precision, high wear resistance, high efficiency, and high stability, meeting the demands of modern manufacturing for high-precision, high-efficiency machining.

[0003] A known authorized patent with application number CN202122079217.4 discloses a cutting tool for machining T-slots to ensure right angles: it includes a first end mill, a second end mill movably mounted above the first end mill, a limit rod fixedly mounted on the upper surface of the first end mill, a second groove cutting edge formed on the upper surface of the first end mill, a first groove cutting edge formed on the outer surface of the first end mill, a third groove cutting edge formed on the outer surface of the second end mill, a limit groove formed on the upper end surface of the second end mill, the limit groove penetrating the second end mill, the limit rod inserted into the limit groove and movably connected to the limit groove, a chuck fixedly mounted on the upper end surface of the limit rod, and a thread fixedly mounted on the outer surface of the chuck near its lower end.

[0004] However, in implementing the relevant technology, the following problems were found in the above technical solution: when the tool is damaged during use, only the tool tip is worn, but when it is replaced, the entire tool needs to be replaced, which wastes the rest of the tool structure. Moreover, when the tool tip is damaged, the entire tool needs to be removed from the CNC machine tool before it can be replaced, which is very slow.

[0005] Therefore, a combined T-groove tool quick-change tool body structure is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0033] Implementation

[0034] Please see Figure 1 -5. A combined T-groove tool quick-change body structure, comprising:

[0035] Fixed block 1;

[0036] Connecting block 2 is fixedly installed at the bottom of fixed block 1;

[0037] The tool holder 3 is slidably set inside the connecting block 2;

[0038] The first fixing unit, which is fixedly installed inside the connecting block 2, is used to fix the tool holder 3;

[0039] The second fixing unit is fixedly installed inside the connecting block 2 and is used to fix the tool holder 3;

[0040] The plug 4 is fixedly installed on the top of the handle 3;

[0041] A tool head fixing structure that is fixedly installed at the bottom of the tool holder 3;

[0042] The cutting head fixing structure includes a fixing plate 5 fixedly installed at the bottom of the cutting handle 3 and a bolt 6 slidably installed inside the fixing plate 5;

[0043] The T-groove cutter head 7 is movably mounted on the outside of the fixed plate 5 by bolts 6.

[0044] The technical solution provided in this embodiment is as follows: When in use, first insert the plug 4 into the inside of the connecting block 2, then tighten the fastener 15 to make the two clamping plates 14 clamp the plug 4, then make the lead screw 10 pass through the slider 9 and threadedly connect the plug 4 and the connecting block 2, then turn the rotating handle 11 to rotate the lead screw 10, and then push the slider 9 through the limiting ring 12 to make the slider 9 clamp the plug 4 with the connecting block 2. When the T-groove cutter head 7 is worn, the bolt 6 can be unscrewed to replace the T-groove cutter head 7.

[0045] Furthermore, the first fixing unit includes a groove 8 formed inside the connecting block 2, a slider 9 slidably disposed inside the groove 8, a lead screw 10 threadedly connected to the connecting block 2 through the slider 9, a rotating handle 11 fixedly installed at one end of the lead screw 10, and a limiting ring 12 fixedly installed outside the rotating handle 11.

[0046] Specifically, by threading the lead screw 10 through the slider 9 and connecting it to the connecting block 2, the slider 9 can be brought closer to the connecting block 2 by the limiting ring 12 when the lead screw 10 is rotated, thereby reducing the distance between the slider 9 and the connecting block 2.

[0047] Furthermore, the second fixing unit includes a movable groove 13 opened inside the connecting block 2, a clamping plate 14 slidably disposed inside the movable groove 13, and a fastener 15 threaded through the connecting block 2. One end of the fastener 15 is located inside the clamping plate 14, and the fastener 15 is rotatably connected to the clamping plate 14.

[0048] Specifically, by rotating the fastener 15 to the clamping plate 14, the clamping plate 14 can be rotated without rotating the fastener 15. This allows the fastener 15 to press against the clamping plate 14 while the fastener 15 is moved, thus clamping the plug 4.

[0049] Furthermore, there are two clamping plates 14 and two fasteners 15, and the two clamping plates 14 are arranged opposite each other on both sides of the plug 4.

[0050] Specifically, by placing two clamping plates 14 opposite each other on both sides of the plug 4, the two fasteners 15 can be screwed on to clamp the plug 4 with the two clamping plates 14, thereby fixing the blade body.

[0051] Furthermore, slider 9 is located between limit ring 12 and plug 4.

[0052] Specifically, by placing the slider 9 between the limiting ring 12 and the plug 4, the slider 9 can be pushed when the screw 10 moves the limiting ring 12, thereby clamping the plug 4 through the connecting block 2 to prevent the plug 4 from shaking.

[0053] Furthermore, the side of the plug 4 closest to the slider 9 is flat, and the side of the plug 4 is parallel to the side of the slider 9.

[0054] Specifically, by making the side of the plug 4 parallel to the side of the slider 9, the friction between the plug 4 and the slider 9 can be increased when the plug 4 is clamped by the connecting block 2 and the slider 9, thus preventing the plug 4 from sliding.

[0055] Furthermore, the top surface of the fixing plate 5 is lower than the top surface of the T-groove cutter head 7, and the top surface of the bolt 6 is also lower than the top surface of the T-groove cutter head 7.

[0056] Specifically, by ensuring that the top surface of the fixing plate 5 and the top surface of the bolt 6 are both lower than the top surface of the T-groove cutter head 7, it is possible to prevent the fixing plate 5 and the bolt 6 from touching the T-groove when the top surface of the T-groove cutter head 7 is cutting the T-groove, thus preventing the tool from affecting the cutting.

[0057] Furthermore, there are multiple bolts 6, and all of the bolts 6 pass through the fixing plate 5 and are threadedly connected to the T-groove cutter head 7.

[0058] Specifically, by threading multiple bolts 6 through the fixing plate 5 and connecting them to the T-groove cutter head 7, the connection between the T-groove cutter head 7 and the fixing plate 5 can be made more stable, preventing the T-groove cutter head 7 from shaking during cutting.

[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
