[0002] Machining tools are tools used for cutting in mechanical manufacturing. In addition to cutting blades, they also include accessories such as tool rods and tool handles. When cutting mechanical parts, the blades come into contact and collide with metal parts, which can easily cause breakage and flying. It is necessary to reprocess the surface of the tool holder and install a protective structure to shield the broken and flying blades and prevent the broken blades from flying everywhere.

[0003] The existing machining tool protection mechanism needs to be repaired and replaced after being hit by multiple broken blades. Since the protection mechanism is generally directly welded and fixed to the surface of the machining tool holder and cannot be disassembled at will, it needs to be improved. Utility Model Content

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a new type of protective structure for mechanical processing tools, including a processing tool holder 1, a mounting ring 2 is rotatably installed on the surface of the processing tool holder 1, two groups of positioning holes 3 are symmetrically provided on both sides of the top of the mounting ring 2, and two groups of positioning clamping columns 13 are symmetrically fixedly installed on both sides of the top of the connecting ring 12, and the positioning clamping columns 13 correspond to the positioning holes 3. By providing the positioning holes 3 and the positioning clamping columns 13, the connecting ring 12 is clamped at the bottom of the mounting ring 2, and the positioning clamping columns 13 are inserted into the corresponding positioning holes 3 to avoid misalignment between the connecting ring 12 and the mounting ring 2 when they are connected.

[0022] The mounting blocks 4 are symmetrically fixedly installed on both sides of the mounting ring 2, and the mounting blocks 4 are provided with mounting grooves 5 inside. The end of the mounting groove 5 away from the processing tool holder 1 is provided with a slide groove 6, and a fixing rod 7 is slidably installed inside the mounting groove 5 and the slide groove 6. The fixing rod 7 is located inside the mounting groove 5 and is fixedly installed with a limit plate 8 on one side surface of the slide groove 6. Because the fixing rod 7 is provided, the toggle lever 10 controls the fixing rod 7 to move, so that the fixing clamping rod 11 can be controlled to move synchronously with the fixing rod 7 inside the slide groove 6;

[0023] A fixing spring 9 is provided on the surface of the fixing rod 7 located inside the mounting groove 5, and a lever 10 and a fixing clamping rod 11 are fixedly installed on the top and bottom of the fixing rod 7 located at one end of the slide groove 6, respectively, and the lever 10 and the fixing clamping rod 11 extend through the slide groove 6 to the outside of the mounting block 4. By providing a fixing spring 9, the limiting plate 8 is pushed toward the side of the mounting groove 5 close to the slide groove 6 under the rebound action of the fixing spring 9, so that the fixing clamping rod 11 can be clamped in the fixing clamping groove 14 to connect the connecting ring 12 with the mounting ring 2.

[0024] A connecting ring 12 is provided at the bottom of the mounting ring 2, and fixed slots 14 are symmetrically provided on both sides of the connecting ring 12, and the fixed slots 14 correspond to the fixed clamping rods 11. Because of the fixed slots 14, after the fixed clamping rods 11 pass through the fixed slots 14 and slide inside the fixed slots 14 to the end away from the processing tool holder 1, it is convenient to connect and fix or separate the connecting ring 12 and the mounting ring 2.

[0025] A protective sleeve 15 is fixedly installed at the bottom of the connecting ring 12, and limiting grooves 16 are symmetrically provided on both sides of the surface of the protective sleeve 15. A limiting protrusion 19 is symmetrically fixedly installed on the top of the surface of the protective sleeve 2 18, and the limiting protrusion 19 corresponds to the limiting groove 16. By providing the limiting groove 16 and the limiting protrusion 19, when the protective sleeve 2 18 is controlled to slide up and down inside the protective sleeve 15, the limiting protrusion 19 slides inside the limiting groove 16, ensuring that the protective sleeve 2 18 will not deflect when sliding up and down inside the protective sleeve 15.

[0026] Positioning screw holes 17 are symmetrically provided on the top and bottom of the surface of the protective sleeve 15, and fixing bolts 25 are symmetrically provided on the surface of the fixed top plate 22, and the fixing bolts 25 pass through the fixed top plate 22 and correspond to the positioning screw holes 17. Because the positioning screw holes 17 and the fixing bolts 25 are provided, the fixing bolts 25 pass through the fixed top plate 22 and are screwed into the corresponding positioning screw holes 17, thereby fixing the fixed top plate 22 on the surface of the protective sleeve 15.

[0027] A protective sleeve 2 18 is slidably installed inside the protective sleeve 15. Mounting plates 20 are symmetrically fixedly installed on both sides of the bottom of the surface of the protective sleeve 2 18, and a clamping rod 21 is fixedly installed on the top of the mounting plate 20, and a fixed top plate 22 is slidably installed on the surface of the top of the two sets of clamping rods 21. The top of the clamping rod 21 passes through the fixed top plate 22 and is fixedly installed with a limited top plate 23. A clamping spring 24 is provided on the surface of the clamping rod 21 located between the mounting plate 20 and the fixed top plate 22. By providing the clamping spring 24, the protective sleeve 2 18 is pressed down under the rebound action of the clamping spring 24, ensuring that the bottom of the protective sleeve 2 18 can be closely attached to the surface of the top of the processed part.

[0028] The working principle of the utility model is:

[0029] Put the connecting ring 12 and the protective sleeve 15 on the surface of the bottom of the processing tool holder 1, push and squeeze the two groups of levers 10 to approach each other, clamp the connecting ring 12 correspondingly at the bottom of the mounting ring 2, make the fixed clamping rod 11 pass through the fixed clamping groove 14, loosen the lever 10, and under the rebound effect of the fixing spring 9, make the fixed clamping rod 11 clamped inside the fixed clamping groove 14, clamp and fix the connecting ring 12 at the bottom of the mounting ring 2, loosen the fixing bolt 25, and pull the protective sleeve 2 18 downward out of the protective sleeve 15 until the limit After the positioning protrusion 19 slides down to the bottom of the limiting groove 16, the fixing bolt 25 is tightened to fix the fixed top plate 22 to the bottom of the surface of the protective sleeve 15. When the machine tool controls the processing tool holder 1 to approach the top of the processing part, the protective sleeve 2 18 is pressed against the top of the processing part under the rebound action of the compression spring 24, ensuring that the processing blade at the bottom of the processing tool holder 1 is blocked by the protective sleeve 15 and the protective sleeve 2 18 when it is damaged and broken during processing, so as to avoid the broken blade flying out of the bottom of the processing tool holder 1 and causing injuries to the processing personnel.
