TECHNICAL FIELD

[0001] The present application belongs to the field of burring machine auxiliary device, and relates to a tool for disassembling and assembling a burring machine cutter head cylinder. BACKGROUND

[0002] During the cutting process of the billet casting flame cutting machine, burrs will appear on the surface of the processed slab due to the action of the cutter. In order to facilitate the removal of the burrs on the surface of the workpiece, a burring machine is often used, which removes the burrs on the surface of the workpiece by cutting. The burring machine often needs to replace the cutter head cylinder and cutter head. Due to the high temperature in the area, the burring machine cutter beam and the cutter head cylinder body are hot, which causes poor working conditions. Because the work is often carried out during the interval of pouring, the working time is often compressed to be very short, which causes long waiting time or repeated work. The cutter head cylinder is a spring structure, and when disassembling and assembling it, the screw structure needs to be used to press down the spring by more than 10mm, or sometimes a crowbar needs to be used to press down the spring by more than 10mm, so as to disassemble the cutter head cylinder. The disassembling and assembling of the cutter head cylinder is very difficult, and at least half an hour is needed to complete the work, two people need to work on both sides of the cutter head to adjust the screw to press down the spring, and another person needs to remove the bottom bolts. The working environment is dangerous, and the labor intensity is large. SUMMARY

[0018] The utility model will be described in detail in combination with the drawings of the specification, but it should be pointed out that the implementation of the utility model is not limited to the following embodiments.

[0019] See Figure 1 , Figure 2 A tool for disassembling and assembling the burr machine cutter head cylinder adopts a lever structure, an arc-shaped pressing plate 4 and a clamp structure in combination, comprising a pressing rod 1, a front positioning rod 2, a rear positioning rod 3 and a pressing plate 4, the front positioning rod 2 and the rear positioning rod 3 are hingedly connected with the pressing rod 1, the pressing plate 4 is fixedly connected with the pressing rod 1 and is arranged between the front positioning rod 2 and the rear positioning rod 3, the pressing plate 4 is in arc-shaped structure, and the front positioning rod 2 and the rear positioning rod 3 are both fixedly provided with a hook plate 5 at the end.

[0020] The front positioning rod 2 and the rear positioning rod 3 are respectively arranged in the two through holes, and are movably connected with the pressing rod 1 through the pin 6. The front positioning rod 2 is limited by the edge of the through hole when rotating to the limit position, and the maximum rotation angle of the front positioning rod 2 is 135 degrees. Similarly, the rear positioning rod 3 is also limited by the corresponding through hole, and the maximum rotation angle of the rear positioning rod 3 is 90 degrees. The end of the pressing rod 1 is provided with a handle 7, which is convenient for the on-site operator to hold. The hook plate 5 is made of round steel or steel plate, and the hook plates 5 on the front positioning rod 2 and the rear positioning rod 3 are oppositely arranged. The front positioning rod 2 and the rear positioning rod 3 are made of square steel or round steel.

[0021] When manufacturing, the pressing rod 1 is made of M25 steel pipe with a length of 700 mm, and two through holes (square holes) are opened in the front part of the steel pipe, the through hole in the front part is 10*50 mm, and the through hole in the rear part is 10*32 mm. The front positioning rod 2 and the rear positioning rod 3 are made of square steel with a thickness of 10 mm, a width of 20 mm and a length of 137 mm, and a round steel with a length of 15.5 mm and a diameter of 9 mm is welded at the end as a hook plate 5. The front positioning rod 2 and the rear positioning rod 3 are respectively inserted into the through hole, and are connected with the pressing rod 1 by using the M10 pin 6, so that the front positioning rod 2 and the rear positioning rod 3 can rotate around the corresponding through hole, and the rotation angle is limited by the length of the through hole. The front positioning rod 2 can be freely rotated by 135 degrees, which is used for early positioning, and the rear positioning rod 3 can be freely rotated by 90 degrees, which plays a role of anti-sliding during pressing, and plays a role of positioning after the pressing is finished. A steel plate with an arc height of 20 mm, a chord length of 100 mm and a thickness of 5 mm is welded on the pressing rod 1 between the front positioning rod 2 and the rear positioning rod 3, which is used as a pressing piece 4. The arc-shaped pressing piece 4 can ensure that the pressing force is always applied to the center of the top surface of the cutter head during the pressing process, and the force is stably output. It is measured and calculated that the cutter head cylinder 8 bottom bolt can be easily removed by pressing 10 mm, and then the cutter head cylinder 8 is removed. Using the original screw rod method needs to press about 100 kg of force to disassemble and assemble the cutter head cylinder 8, and using the tool can achieve the effect with about 10 kg of force, which is easy and labor-saving, and convenient for construction.

[0022] When the tool head cylinder 8 is disassembled and assembled on site, the maintenance personnel stand on one side of the tool head cylinder 8, hold the handle 7 of the tool with one hand, and hook the hook plate 5 of the front positioning rod 2 into the front side positioning hole of the burring machine with the other hand. The hook plate 5 of the rear positioning rod 3 naturally falls on the outer edge of the rear tool head cylinder 8, plays the role of a fixture, and prevents the pressure rod 1 from moving forward. The pressure rod 1 is pressed, the arc-shaped pressing piece 4 rotates with the pressure rod 1, and the arc-shaped pressing piece 4 is in contact with the center of the top surface of the tool head at all times during the pressing process, so that the pressing force is stably output. A force of about 10 kg is used to press down the pressure rod 1, and when the pressure rod 1 is parallel to the tool head, the hook plate 5 of the rear positioning rod 3 is hooked into the rear side positioning hole of the burring machine, so that the tool is fixed, and the bottom bolts can be disassembled. The pressure rod 1 is pressed down, the hook plate 5 of the rear positioning rod 3 is taken out from the rear side positioning hole of the burring machine, the pressure rod 1 is reversely rotated, the pressing piece 4 is separated from the tool head, the hook plate 5 of the front positioning rod 2 is taken out from the front side positioning hole of the burring machine, and the tool head cylinder 8 to be replaced is disassembled. The new tool head cylinder 8 can be installed by reverse operation.

[0023] The utility model improve work efficiency, shorten equipment's overhaul time, reduce labour intensity. Guarantee operating personnel personal safety, guarantee overhaul quality. The utility model simple structure, convenient on -the -spot operation, is worth using widely.
