[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a CNC lathe tool post, including a tool post body 1. A fixing bolt 2 is threadedly connected to the upper surface of the tool post body 1. An installation groove 3 is provided on the outer side of the tool post body 1, into which a tool can be inserted for installation. After insertion, the fixing bolt 2 can be turned to move downwards relative to the tool post body 1, thereby clamping and fixing the middle of the tool. A groove 4 is provided on the right side of the front of the tool post body 1. A clamping bolt 5 is threadedly connected to the upper surface of the tool post body 1, with its bottom end penetrating through the tool post body 1. The clamping bolt 5 is threadedly connected to the tool post body 1. When the clamping bolt 5 is turned, it can move up and down relative to the tool post body 1. The L-shaped clamping frame 6 is rotatably connected to the bottom end of the clamping bolt 5. When the clamping bolt 5 moves, it can drive the L-shaped clamping frame 6 to move synchronously. The front end of the L-shaped clamping frame 6 is slidably connected to the inside of the groove 4. The groove 4 can guide and limit the movement of the L-shaped clamping frame 6, so that the L-shaped clamping frame 6 can only move in a straight line in the up and down direction. The inner surface of the front side of the L-shaped clamping frame 6 is in contact with the inner wall of the groove 4. When the tool is inserted into the mounting groove 3, after tightening the fixing bolt 2 to clamp and fix the middle part of the tool, the clamping bolt 5 can be tightened to drive the L-shaped clamping frame 6 to move downward under the limit of the groove 4, clamping and limiting the front side of the tool, making the tool more stable.
[0033] Reference Figure 1 , Figure 2 and Figure 4 A baffle 7 is fixedly connected to the front side of the mounting slot 3. A sealing plate 8 is provided on the right side of the baffle 7. The front of the L-shaped clamping bracket 6 is in contact with the back of the sealing plate 8. The upper and lower surfaces of the baffle 7 and the sealing plate 8 are in contact with the inner wall of the mounting slot 3. A limit unit is provided on the left side of the sealing plate 8. The tool holder body 1 is also provided with grooves 4, clamping bolts 5 and L-shaped clamping brackets 6 on the other three sides except the front outer side. Similarly, the mounting slot 3 is also provided with baffles 7, sealing plates 8 and limit units on the other three sides except the front outer side to ensure complete sealing of the inside of the mounting slot 3. In the initial state, the four sets of baffles 7 and sealing plates 8 can completely seal the inside of the mounting slot 3. When it is necessary to install the tool, the sealing plate 8 can be pulled to one side of the baffle 7 to open the mounting slot 3, so that the tool can be inserted into the mounting slot 3 and fixed by the cooperation of the fixing bolts 2 and the clamping bolts 5.
[0034] The limiting unit comprises a sliding groove 81, a sliding block 82 and an elastic piece 83. The sliding groove 81 is arranged on the back surface of the baffle 7. The sliding block 82 is in sliding connection with the inside of the sliding groove 81. The sliding block 82 can move along the path of the sliding groove 81 in the inside of the sliding groove 81. The back surface of the sliding block 82 is fixedly connected with the front surface of the sealing plate 8. When the sealing plate 8 moves, it can drive the sliding block 82 to move synchronously. The elastic piece 83 is fixedly connected with the left side surface of the sliding block 82. The left end of the elastic piece 83 is fixedly connected with the left side inner wall surface of the sliding groove 81. When the sliding block 82 moves to the elastic piece 83, the elastic piece 83 is extruded, so that the elastic piece 83 is compressed to generate elastic potential energy. In the initial state, the elastic potential energy of the elastic piece 83 limits the sealing plate 8, so that the sealing plate 8 can cooperate with the baffle 7 to seal and protect the inside of the mounting groove 3, so as to avoid the adhesion of debris in the inside of the mounting groove 3, which affects the accurate installation of the subsequent cutter.
[0035] Referring to Figure 3 and Figure 5 , the upper surface of the L-shaped clamping frame 6 is provided with a guide groove 9. The inside of the groove 4 is fixedly connected with a fixed plate 10. The bottom surface of the fixed plate 10 is fixedly connected with a guide rod 11. The guide rod 11 is inserted into the inside of the guide groove 9. The guide rod 11 can move linearly in the up-down direction relative to the guide groove 9, so as to further guide and limit the movement of the L-shaped clamping frame 6, so as to ensure that the L-shaped clamping frame 6 can only move linearly in the up-down direction, avoiding the offset in the groove 4 and being stuck and unable to move, which affects the fixed installation effect of the cutter.
[0036] Working principle: when the cutter needs to be installed, the sealing plate 8 can be pulled to open the mounting groove 3. At this time, the sealing plate 8 drives the sliding block 82 to move synchronously, extruding the elastic piece 83. Then the cutter can be inserted into the inside of the mounting groove 3. The front and rear tightening of the fixed screw 2 and the clamping screw 5 clamps and fixes the cutter. At this time, the cutter can be used to process materials. After the cutter is removed, the sealing plate 8 is automatically reset under the elastic potential energy of the elastic piece 83 to seal the inside of the mounting groove 3. When the cutter is inserted into the inside of the mounting groove 3, the clamping screw 5 drives the L-shaped clamping frame 6 to move synchronously. At this time, the L-shaped clamping frame 6 can seal the space above the cutter, so that the debris cannot enter the inside of the mounting groove 3 from the upper side of the cutter when the cutter is used, further improving the sealing and protection effect of the inside of the mounting groove 3.
[0037] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
