Since the limiting block is movably arranged in the inner groove, and the limiting block and the inner groove are concentric, and the radian of the limiting block is greater than that of the inner groove, so a part of the limiting block is disengaged from the inner groove. Therefore, a small piece of positioning block at the front end of the limiting groove will squeeze the protruding limiting block and make it rotate into the inner groove. Since the radian of the inner groove is not enough to completely accommodate the limiting block, the other end of the limiting block will protrude from the inner groove and rotate and be clamped on the inner wall of the limiting groove, so that the limiting block is clamped with the limiting groove. Due to the limitation of the clamping of the limiting block and the limiting groove, the supporting slider cannot move on the slide rail towards the metal clamping block, thus avoiding the contact between the tool and the metal clamping block, and realizing the anti-collision of the tool of the machine tool main body.

Detailed Description of the Invention

[0032] In order to clearly and completely describe the objectives, technical solutions of the present invention, and make the advantages more clearly understood, the following further elaborates on the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all embodiments. They are merely used to explain the embodiments of the present invention and are not used to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0033] Please refer to Figures 1 to 9 , the present invention provides a technical solution: a tool anti-collision structure for a metal cutting machine tool.

[0034] Embodiment 1, a tool anti-collision structure for a metal cutting machine tool, includes: a metal clamp block 2 is fixed on the side surface of the machine tool main body 1, a metal clamp block 2 and a rack 4 are fixed on the upper surface of the machine tool main body 1, a positioning groove 7 is provided on the side surface of the slide rail 3, an inner groove 14 is provided inside the slide rail 3, a limiting block 6 and a first spring 12 are movably arranged on the inner wall of the inner groove 14. The limiting block 6 and the inner groove 14 are concentric circles, and the radian of the limiting block 6 is greater than that of the inner groove 14. Therefore, a part of the limiting block 6 protrudes out of the inner groove 14. So, a small positioning block 17 at the front end of the limiting groove 19 will squeeze the protruding limiting block 6 and make it rotate into the inner groove 14. Since the radian of the inner groove 14 is not enough to completely accommodate the limiting block 6, the other end of the limiting block 6 will protrude out of the inner groove 14 and rotate and be clamped on the inner wall of the limiting groove 19, so that the limiting block 6 is clamped with the limiting groove 19. Due to the limitation of the clamping of the limiting block 6 and the limiting groove 19, the support slider 8 cannot move on the slide rail 3 in the direction of the metal clamp block 2, thus avoiding the contact between the tool 5 and the metal clamp block 2, and thus realizing the anti-collision of the tool 5 of the machine tool main body 1.

[0035] A support slider 8 is fixed at the lower end of the tool 5, a positioning block 17 is fixed on the inner side surface of the support slider 8, a rigid sponge 18 is fixed on the side surface of the positioning block 17, a limiting groove 19 is provided on the side surface of the positioning block 17, an inner cavity 22 and an oil storage cavity 27 are provided inside the positioning block 17, a stirring blade 25 is movably arranged inside the oil storage cavity 27, a gear 10 is fixed at the end of the stirring blade 25. Since the rack 4 and the gear 10 are mutually clamped, when the machine tool main body 1 controls the support slider 8 to move on the slide rail 3, it will drive the gear 10 to rotate, thereby driving the stirring blade 25 to rotate in the oil storage cavity 27. The rotating stirring blade 25 will stir the lubricating oil in the oil storage cavity 27, so that the lubricating oil will not coagulate and accumulate. A hand wheel 9 is fixed at the end of the gear 10, and the hand wheel 9 allows manual operation of the machine tool main body 1 by a person.

[0036] On the basis of the first embodiment, in order to prevent the tool 5 from colliding when the main body 1 of the metal cutting machine cuts metal, a fixing plate 13 is fixed on the inner wall side surface of the inner groove 14, a sector block 15 is fixed on the bottom surface of the inner wall of the inner groove 14, a baffle 11 is fixed on the side surface of the limiting block 6, and a sector groove 16 is formed on the end surface of the limiting block 6.

[0037] The sector block 15 corresponds to and is clamped with the sector groove 16, showing a movable connection. On the one hand, it positions the limiting block 6 in the inner groove 14 to prevent the limiting block 6 from shifting. On the other hand, it makes the limiting block 6 and the inner groove 14 be in a movable connection. One end of the first spring 12 is fixed on the surface of the fixing plate 13, and the other end of the first spring 12 is fixed on the surface of the baffle 11. The inner groove 14 communicates with the positioning groove 7, and the function of the first spring 12 is to reset the limiting block 6.

[0038] The support slider 8 is movably clamped on the outer surface of the slide rail 3. The positioning block 17 corresponds to and is movably clamped with the positioning groove 7, and the limiting block 6 corresponds to and is movably clamped with the limiting groove 19. Due to the restriction of the clamping of the limiting block 6 and the limiting groove 19, the support slider 8 cannot move on the slide rail 3 towards the metal clamping block 2, thus avoiding the contact between the tool 5 and the metal clamping block 2, and realizing the anti-collision of the tool 5 of the machine tool main body 1.

[0039] A push rod 20 is movably inserted through the inner wall of the limiting groove 19. A second transmission plate 24 is fixed at the end of the push rod 20. A first slide plate 23 is movably arranged at the end of the second transmission plate 24. A first transmission plate 21 is movably arranged at the end of the first slide plate 23. A second slide plate 31 is movably arranged at the end of the first transmission plate 21. The length of the end of the second transmission plate 24 fixed to the push rod 20 is less than the length of the other end. The length of the end of the first transmission plate 21 movably connected to the first slide plate 23 is less than the length of the other end. Therefore, when the end with a smaller length drives the end with a larger length to rotate, the moving distance of the end with a larger length will be greater.

[0040] One end of the push rod 20 is located on the inner wall of the limiting groove 19, and the other end of the push rod 20 is movably inserted into the inner cavity 22. The first transmission plate 21, the first slide plate 23, the second transmission plate 24 and the second slide plate 31 are all movably located on the inner wall of the inner cavity 22.

[0041] A guide rod 26 is fixed on the inner wall side surface of the inner cavity 22 away from the rigid sponge 18. A second spring 30 is movably sleeved on the outer surface of the guide rod 26. The function of the second spring 30 is to reset the first slide plate 23 and, through the first slide plate 23, reset the push rod 20.

[0042] A support lug 29 is fixed on the side surface of the first slide plate 23. The support lug 29 corresponds to and is clamped with the guide rod 26, showing a movable connection, which positions the first slide plate 23 to prevent the first slide plate 23 from shifting during movement in the inner cavity 22.

[0043] A connection port 32 is provided on the lower end surface of the second slide plate 31, and the connection port 32 penetrates the second slide plate 31. An oil outlet 28 is provided on the inner wall surface of the oil storage chamber 27 close to the rigid sponge 18. The oil outlet 28 communicates with the rigid sponge 18 and the oil storage chamber 27, and the oil outlet 28 corresponds to the connection port 32.

[0044] The gear 10 corresponds to and engages with the rack 4, and is movably connected. There are two sets of gears 10, and the two sets of gears 10 are symmetrically distributed on both sides of the support slider 8. The handwheel 9 is fixed to the end surface of the outer gear 10. Since the rack 4 and the gear 10 engage with each other, when the machine tool main body 1 controls the support slider 8 to move on the slide rail 3, it will drive the gear 10 to rotate, thereby driving the stirring blade 25 to rotate in the oil storage chamber 27. The rotating stirring blade 25 will stir the lubricating oil in the oil storage chamber 27 to prevent the lubricating oil from coagulating and accumulating.

[0045] In actual use, when the machine tool main body 1 is used to cut metal, first fix the metal with the metal clamp block 2, then start the machine tool main body 1. The machine tool main body 1 will drive the support slider 8 to move on the slide rail 3. When the distance between the cutting tool 5 on the support slider 8 and the metal clamp block 2 reaches the preset value, the machine tool main body 1 will drive the metal to rotate at a high speed through the metal clamp block 2, so that the cutting tool 5 cuts the metal. During cutting, the machine tool main body 1 will continue to drive the support slider 8 to move on the slide rail 3 to cut the metal into the required shape. When there is an error in uploading the working program, the metal to be cut is not fixed stably, and the cutting tool is worn after long-term use, when the cutting tool 5 moves towards the metal clamp block 2 and is about to touch, a small positioning block 17 at the front end of the limit groove 19 will contact the limit block 6. Since the limit block 6 is movably arranged in the inner groove 14, and the limit block 6 and the inner groove 14 are concentric, and the radian of the limit block 6 is greater than the radian of the inner groove 14, so a part of the limit block 6 is disengaged from the inner groove 14. Therefore, a small positioning block 17 at the front end of the limit groove 19 will squeeze the protruding limit block 6 and make it rotate into the inner groove 14. Since the radian of the inner groove 14 is not enough to completely accommodate the limit block 6, the other end of the limit block 6 will protrude from the inner groove 14 and rotate and be clamped on the inner wall of the limit groove 19, so that the limit block 6 is clamped with the limit groove 19. Due to the restriction of the clamping of the limit block 6 and the limit groove 19, the support slider 8 cannot move towards the metal clamp block 2 on the slide rail 3, thus avoiding the contact between the cutting tool 5 and the metal clamp block 2, and realizing the anti-collision of the cutting tool 5 of the machine tool main body 1; when the limit block 6 is clamped in the limit groove 19, since the limit block 6 is rotated into the limit groove 19, the limit block 6 will push the push rod 20, so that the push rod 20 moves in an arc to the inner bin 22. Since the second transmission plate 24 and the first transmission plate 21 are in an 'L' shape, and the bending parts of the first transmission plate 21 and the second transmission plate 24 are movably inserted through the support rods fixed inside the inner bin 22, the arc movement of the push rod 20 will drive one end of the second transmission plate 24 to rotate around its bending part, so that the other end of the second transmission plate 24 pushes the first slide plate 23 to move and squeezes the second spring 30 through the support lug 29. The movement of the first slide plate 23 will push one end of the first transmission plate 21 to rotate around its bending part, so as to push the second slide plate 31 to move into the oil storage bin 27 through the first transmission plate 21, so that the connection port 32 opened on the second slide plate 31 corresponds to the oil outlet 28 opened on the inner wall of the oil storage bin 27, so that the lubricating oil inside the oil storage bin 27 flows to the rigid sponge 18 and wets the rigid sponge 18, thus playing a lubricating role in the movement of the support slider 8 on the slide rail 3; when the limit block 6 is not clamped in the limit groove 19, since the rack 4 and the gear 10 are clamped with each other, the machine tool main body 1 controls the movement of the support slider 8 on the slide rail 3 to drive the gear 10 to rotate, thus driving the stirring blade 25 to rotate in the oil storage bin 27. The rotating stirring blade 25 will stir the lubricating oil in the oil storage bin 27 so that the lubricating oil will not coagulate and accumulate;The function of the first spring 12 is to reset the limit block 6, and the function of the second spring 30 is to reset the first slide plate 23 and, through the first slide plate 23, reset the push rod 20.
