[0028] By setting the motor inside the power seat 2, it is convenient to rotate the fixed chuck 3 and drive the milling cutter 4, and then the motor 10, the wires and the external power supply are electrically connected to start, thereby driving the screw rod 9 to rotate, and at the same time, the movable plate slides on the guide rail, thereby driving the connecting seat 5 to make the drill bit 6 and the milling cutter 4 close to each other, thereby facilitating the processing of the horseshoe groove, and the protection component 7 and the protection plate are set to facilitate the protection of the residue, and the collection component 8 is set to facilitate the collection of the residue.

[0029] like Figure 2 - Figure 3 As shown, the protection component 7 includes a U-shaped cover shell 71, and the opposite surfaces of the inner sides of the U-shaped cover shell 71 in the vertical direction are fixedly connected with sliders 74, and the outer surface of the slider 74 is slidably connected to the inside of the groove, and the right side of the U-shaped cover shell 71 in the horizontal direction is fixedly connected with a spring plate 72, and the left and front sides of the spring plate 72 are fixedly connected with springs 73, and the front side of the U-shaped cover shell 71 in the vertical direction is overlapped with an L-shaped plate 1, and the rear side of the L-shaped plate 1 75 in the horizontal direction is fixedly connected to the surface of the workbench 1, and the left side of the upper surface of the L-shaped plate 1 75 is fixedly connected with an L-shaped plate 2 76, and the right side of the L-shaped plate 2 76 is fixedly connected with a stopper, and the lower surface of the L-shaped plate 2 76 in the horizontal direction is overlapped with a fixed block 77, and the front side of the fixed block 77 is fixedly connected with a positioning plate 78, and the left side of the positioning plate 78 is plugged with a plug plate 79, and the outer surface of the L-shaped plate 2 76 in the horizontal direction is the same length as the U-shaped cover shell 71, and the rear side of the fixed block 77 is fixedly connected to the outer surface of the U-shaped cover shell 71;

[0030] When it is needed, the U-shaped cover 71 is pushed to make the slider 74 slide inside the groove in the power seat 2. Due to the action of the spring plate 72, the spring 73 is driven to contact the surface of the power seat 2 after moving to the appropriate position, thereby squeezing and contracting the spring 73. At the same time, when the U-shaped cover 71 moves, it drives the fixing block 77 and the positioning plate 78, so that the fixing block 77 slides between the vertical upper surface of the L-shaped plate 1 75 and the horizontal lower surface of the L-shaped plate 2 76. When sliding to the appropriate position, the surface of the fixing block 77 contacts the vertical surface of the L-shaped plate 2 76. Then, by inserting the plug plate 79 into the interior of the positioning plate 78, the plug plate 79 overlaps the left side of the L-shaped plate 2 76 in the vertical direction, thereby limiting the position of the U-shaped cover 71, thereby protecting the residue during processing. When it needs to be opened, the plug plate 79 is directly pulled out. Due to the elastic force of the contracted spring 73, the U-shaped cover 71 is pushed to move, thereby facilitating its opening.

[0031] like Figure 4 - Figure 6As shown, the collecting assembly 8 includes a square plate 81, a collecting box 82 is fixedly connected to the rear side of the square plate 81, a limit line is set on the inner wall of the collecting box 82, a U-shaped handle is fixedly connected to the middle of the front side of the square plate 81, a vertical groove 83 communicating with the inside and outside is opened on the upper front side of the square plate 81 and the upper rear side of the inner wall of the collecting box 82, a strip plate 84 is slidably connected to the inside of the vertical groove 83, the rear side of the outer surface of the strip plate 84 extends to the outside, the rear side of the strip plate 84 is provided with an inclined surface 1, and the middle of the rear side of the collecting box 82 is fixedly connected There is a mounting plate 801, the rear side of the mounting plate 801 is fixedly connected with an L-shaped mounting plate 802, the rear side of the vertical outer surface of the L-shaped mounting plate 802 is fixedly connected to the inside of the workbench 1, the rear side of the upper surface of the mounting plate 801 is movably connected with an L-shaped clamping block 803, the horizontal lower surface of the L-shaped clamping block 803 is overlapped with a positioning rod 804, the left and right ends of the positioning rod 804 are fixedly connected with a block 805, the front side of the block 805 is fixedly connected to the rear side of the collection box 82, and the front side of the L-shaped clamping block 803 is provided with an inclined surface 2;

[0032] During processing, the processed residue is protected from splashing by the protective component 7, so that the residue passes through the square opening and falls into the collection box 82, which is convenient for collecting the residue. By setting the internal limit line of the collection box 82, it is convenient to clean the internal residue of the collection box 82 to prevent the excess residue from moving out from the inside through the vertical groove 83. When the residue is aligned with the limit line, it is necessary to clean the residue. The strip plate 84 is pushed forward so that the inclined surface 1 in the strip plate 84 contacts the inclined surface 2 of the L-shaped block 803, and then the strip plate 84 is moved upward. The strip plate 84 enables the L-shaped block 803 to move upward, so that the L-shaped block 803 is separated from the surface of the positioning rod 804, and then the square plate 81 and the collection box 82 are moved out from the inside by pulling the U-shaped handle, so as to clean the residue. When the cleaning is completed, the collection box 82 is inserted into the inside of the workbench 1. At the same time, due to the setting of the positioning rod 804 and the inclined surface 2 in the L-shaped block 803, the L-shaped block 803 moves upward. When the collection box 82 slides completely inside the workbench 1, the L-shaped block 803 just catches the positioning rod 804, thereby limiting its position.

[0033] The working principle of the machine tool for processing the horseshoe groove of the drill bit will be described in detail below.

[0034] When it is needed, the U-shaped cover 71 is pushed to make the slider 74 slide inside the groove in the power seat 2. Due to the action of the spring plate 72, the spring 73 is squeezed and contracted, and the fixing block 77 and the positioning plate 78 are driven. Then, the insert plate 79 is inserted into the interior of the positioning plate 78 so that the insert plate 79 overlaps the left side of the L-shaped plate 2 76 in the vertical direction, thereby limiting the position of the U-shaped cover 71. When processing, the residue after processing is protected by the protective component 7 to prevent splashing, so that the residue passes through the square opening and falls off. The residue falls into the collection box 82, which facilitates the collection of the residue. When the residue is aligned with the limit line, the residue needs to be cleaned by pushing the strip plate 84 forward so that the inclined surface 1 in the strip plate 84 contacts the inclined surface 2 of the L-shaped block 803, and then the strip plate 84 is moved upward so that the L-shaped block 803 moves upward, so that the L-shaped block 803 is separated from the surface of the positioning rod 804, and then the U-shaped handle is pulled to move the square plate 81 and the collection box 82 out from the inside to clean the residue.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
