[0023] Reference Figure 1 to Figure 2As shown, a machine tool cutter head replacement device described in an embodiment of the utility model comprises a fixing ring 1; a plurality of spring rods 11 are slidably connected to the middle of the fixing ring 1; a fixing plate 12 is fixedly connected to the side wall of the fixing ring 1; a connecting shaft 13 is fixedly connected to the side wall of the fixing plate 12; during operation, when the machine tool cutter head is replaced, the fixing ring 1 is sleeved on the machine tool cutter head, at which time the end of the spring rod 11 will contact the surface of the cutter head, and at the same time, the stretching of the spring rod 11 will generate a rebound force acting on the cutter head, at which time the cutter head can be clamped and fixed, and then the bolts between the cutter head and the machine tool are removed, Pull the connecting shaft 13 to drive the fixing ring 1 and the spring rod 11 to remove the cutter head from the machine tool. When installing, place the new cutter head in the fixing ring 1 so that the spring rod 11 clamps and fixes it, and then put it on the machine tool to fix it. In this step, by setting the fixing ring 1 to connect the spring rod 11, the spring rod 11 can clamp and fix the cutter head from the side of the cutter head when replacing the cutter head of the machine tool. When the stretching distance of the spring rod 11 is different, the cutters of different sizes can be clamped and fixed, so as to reduce the situation where the size of the replacement device does not match when replacing cutter heads of different sizes, and the frequent adjustment of the replacement device leads to cumbersome operation.

[0024] Reference Figure 2 As shown, the end of the spring rod 11 is connected to a hinge shaft 2; the side wall of the hinge shaft 2 is connected to a hinge plate 21; during operation, when the end of the fixing ring 1 is close to the surface of the cutter head, the hinge plate 21 will contact the surface of the cutter head, and at the same time, the hinge plate 21 will change its angle, so that the plane of the hinge plate 21 contacts the surface of the cutter head. In this step, the hinge shaft 2 is set to connect the hinge plate 21 and the spring rod 11, so that when the spring rod 11 clamps and fixes the cutter head, the hinge plate 21 will change its angle on the surface of the cutter head, which can increase the contact area between the surface of the cutter head and the spring rod 11 when the cutter head is polygonal, so that the spring rod 11 can fix the cutter head more firmly to improve the applicability and stability of clamping and fixing.

[0025] Reference Figure 1 As shown, the side walls of the two hinge plates 21 close to each other are fixed with elastic bands 3; the elastic bands 3 are flexibly arranged; during operation, when the hinge plate 21 contacts the surface of the cutter head, the elastic band 3 will contact the surface of the cutter head as the angle of the hinge plate 21 changes, and at this time the elastic band 3 will deform and clamp on the surface of the cutter head. In this step, by setting the elastic band 3 to connect the hinge plate 21, the elastic band 3 can be clamped on the surface of the cutter head when the hinge plate 21 clamps and fixes the cutter head, thereby increasing the fixing effect on the cutter head and improving the stability of the cutter head when it is fixed.

[0026] Reference Figure 1 to Figure 2As shown, a plurality of suction cups 4 are fixedly connected to the side wall of the hinge plate 21; the suction cups 4 are evenly distributed on the side wall of the hinge plate 21; during operation, when the hinge plate 21 contacts the surface of the cutter head, the suction cups 4 will be adsorbed on the surface of the cutter head to increase the tightness of the connection between the cutter head and the hinge plate 21. In this step, by arranging the suction cups 4 to connect the hinge plate 21, when the hinge plate 21 clamps and fixes the cutter head, the suction cups 4 can be adsorbed on the surface of the cutter head to improve the tightness of the connection between the cutter head and the hinge plate 21, so as to reduce the slippage of the cutter head when it is fixed.

[0027] Reference Figure 3 As shown, a plurality of water spray holes 5 are provided in the middle of the fixing plate 12; a connecting pipe 51 is connected to the side wall of the water spray hole 5; an annular water pipe 52 is connected to the end of the connecting pipe 51; a water inlet pipe 53 is connected to the side wall of the annular water pipe 52; during operation, the cutter head is removed and the water source is connected to the water inlet pipe 53. At this time, water enters the annular water pipe 52 from the water inlet pipe 53, then enters the connecting pipe 51 and is sprayed onto the cutter head from the water spray hole 5, so that the cutter head can be rinsed. In this step, the water spray hole 5 is provided to connect the connecting pipe 51, the annular water pipe 52 and the water inlet pipe 53, so that the cutter head can be rinsed after it is removed, and the oil and dust on the cutter head can be washed away to improve the cleanliness of the cutter head surface.

[0028] Reference Figures 1 to 4 As shown, a plurality of collecting grooves 6 are provided on the side wall of the fixing ring 1; a collecting box 61 is installed at the bottom of the fixing ring 1; during operation, part of the sewage will fall into the collecting groove 6 below when the cutter head is flushed, and then the sewage enters the collecting box 61 from the collecting groove 6, at which time the collecting box 61 will collect the sewage, and when the collection is completed, the collecting box 61 will be removed and the sewage will be poured out for centralized treatment, and then the collecting box 61 will be installed and reset. In this step, by setting the collecting groove 6 and the collecting box 61, part of the sewage generated by flushing the cutter head can be collected to reduce the pollution caused by the sewage flowing to the surrounding area.

[0029] Reference Figure 4 As shown, the inner wall of the collection box 61 is provided with a first filter screen 7; the first filter screen 7 is detachably installed; during operation, when the sewage enters the collection box 61 and flows toward the bottom, it will pass through the first filter screen 7, at which time the first filter screen 7 will filter the sewage and filter out impurities such as metal debris mixed in the sewage. After the filtration is completed, the first filter screen 7 will be removed and cleaned and then installed and reset. In this step, the first filter screen 7 can be set to filter the sewage entering the collection box 61, so as to reduce the accumulation of impurities such as metal debris mixed in the sewage at the bottom of the collection box 61, which is inconvenient to clean and affects the collection of sewage.

[0030] Reference Figure 1As shown, the side wall of the fixed plate 12 is provided with a second filter 8; the second filter 8 is detachably installed; during operation, when the cutter head is flushed in the fixed ring 1, the second filter 8 will be blocked between the water spray hole 5 and the cutter head. This step sets the second filter 8 between the cutter head and the water spray hole 5, which can reduce the metal debris and impurities on the cutter head from entering the water spray hole 5 and causing blockage when flushing the cutter head.

[0031] During operation, when replacing the cutter head of the machine tool, the fixing ring 1 is put on the cutter head of the machine tool. At this time, the end of the spring rod 11 will contact the surface of the cutter head, and the stretching of the spring rod 11 will generate a rebound force on the cutter head. At this time, the cutter head can be clamped and fixed. Then, after the bolts between the cutter head and the machine tool are removed, the connecting shaft 13 is pulled to drive the fixing ring 1 and the spring rod 11 to remove the cutter head from the machine tool. During installation, the new cutter head is placed in the fixing ring 1 so that the spring rod 11 clamps and fixes it, and then it is placed on the machine tool and fixed. When the end of the fixing ring 1 is close to the surface of the cutter head, the hinge plate 21 will contact the surface of the cutter head, and at the same time, the hinge plate 21 will change its angle, so that the plane of the hinge plate 21 will contact the surface of the cutter head. When the hinge plate 21 contacts the surface of the cutter head, the elastic band 3 will contact the surface of the cutter head as the angle of the hinge plate 21 changes. At this time, the elastic band 3 will deform and be clamped on the surface of the cutter head. When the hinge plate 21 contacts the surface of the cutter head, the suction cup 4 will be adsorbed on the cutter head. The surface of the head increases the tightness of the connection between the cutter head and the hinge plate 21. After the cutter head is removed, the water source is connected to the water inlet pipe 53. At this time, water enters the annular water guide pipe 52 from the water inlet pipe 53, and then enters the connecting pipe 51 and is sprayed onto the cutter head from the water spray hole 5, so as to rinse the cutter head. When the cutter head is rinsed, part of the sewage will fall into the collecting trough 6 below, and then the sewage enters the collecting box 61 from the collecting trough 6. At this time, the collecting box 61 will collect the sewage. When the collection is completed, the collecting box 61 will be removed and the sewage will be poured out for centralized treatment, and then the collecting box 61 will be installed and reset. When the sewage enters the collecting box 61 and flows to the bottom, it will pass through the first filter screen 7. At this time, the first filter screen 7 will filter the sewage and filter out impurities such as metal debris mixed in the sewage. After the filtration is completed, the first filter screen 7 will be removed and cleaned and then installed and reset. When the cutter head is rinsed in the fixing ring 1, the second filter screen 8 will block between the water spray hole 5 and the cutter head.

[0032] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
