Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a novel cutting frame structure of a square cutting machine. Background Art

[0002] In industrial processing, the square cutter is a highly efficient mechanical equipment used for precise cutting and square cuts of hard materials such as wood and stone. This machine usually has a wooden box-like appearance, with a high-speed rotating cutting tool or cutting wire inside. The depth, speed and angle of the cutting can be precisely controlled through the operating console, so as to achieve fast and accurate cutting of the material. During the use of the square cutter, due to the fast rotation speed of the center shaft and the need for periodic reversal during cutting, the wire wheel has high requirements for the stability of the cutting wire during high-speed rotation and reversal cutting. The load generated by long-term operation will cause friction between the center shaft and the output shaft of the drive motor, and the center shaft and the output shaft of the drive motor will wear each other, resulting in bearing shaking and bolt breakage on the clamp block, which not only increases the maintenance frequency and the cost due to frequent wire breakage, but also easily leads to safety hazards.

[0003] In order to solve the above problems, a utility model patent with publication number CN210589983U discloses a square cutting machine, which arranges a groove on the first connecting disk and a protrusion on the second connecting disk so that the protrusion can be inserted into the groove, thereby connecting the output shaft to the connecting shaft, and then fixes the first connecting disk and the second connecting disk through a connecting component. This not only improves the stability of the connection between the output shaft and the connecting shaft, but also reduces the friction between the output shaft and the connecting shaft, thereby improving the technical effect of the stability of the cutting wheel and the cutting line on the connecting shaft.

[0004] There are still some shortcomings in the installation and use of the above-mentioned square cutting machine. Bolt holes are set at both ends of the cutting frame of the square cutting machine so that the bearing box fits tightly on the frame. When the shaft head of the square cutting machine shakes, the bearing box needs to be disassembled for maintenance. However, it takes a long time to disassemble the bearing box. It is necessary to screw multiple bolts and nuts to remove the bearing box, which is more troublesome. The efficiency of disassembling the bearing box is low, the construction period is delayed, and multiple people are required to cooperate in disassembly, thereby wasting human resources.

First springs 9 are provided on the outer sides of the screw rods 8 and the fixing rods 6 to rebound after being pulled. A contraction groove 10 is provided at the top of the card plate 7 to facilitate the contraction of the push plate 14. An installation groove 11 is provided in the middle part of the top of the card plate 7. The inner bottom end of the installation groove 11 is fixedly connected with a second spring 12. One end of the second spring 12 is fixedly connected with a push plate 14 to push the push plate 14 with elastic force. A nut 15 is threadedly connected to the outer side of the screw rod 8 to fix the position of the screw rod 8 and the fixing rod 6 after moving.

[0032] A connecting groove 16 is provided on the inner side of the fixing plate 2, and a bidirectional screw rod 17 is rotatably connected to the left and right sides of the inside of the connecting groove 16, and the other end of the bidirectional screw rod 17 is fixedly connected to a synchronous wheel 22, and a synchronous belt 23 is provided on the outer sides of the two synchronous wheels 22, so that when the left synchronous wheel 22 rotates, the right synchronous wheel 22 is driven to rotate through the synchronous belt 23, thereby driving the rotation of the right bidirectional screw rod 17, and the upper and lower sides of the outer side of the bidirectional screw rod 17 are threadedly connected with adjustment plates 18, which is convenient for adjusting the size of the mounting hole 3, and the opposite sides of the plurality of adjusting plates 18 are fixedly connected to a fixing shell 19, and the inner opposite sides of the plurality of fixing shells 19 are fixedly connected to two push springs 20, and the other end of the push spring 20 is fixedly connected to a push column 21, which plays an elastic pushing role on the push column 21, thereby enhancing the tightness of the installation, and the left and right sides of the fixing plate 2 are provided with a plurality of thread holes 24, which assist in the installation and enhance the stability of the bearing box installation.

[0033] Working principle: first, make slots on the upper and lower sides of the bearing chamber that are adapted to the size of the card plate 7. When disassembling the bearing chamber, first twist the nut 15 so that the nut 15 loosens the screw 8, and then pull the handle 27. The handle 27 drives the two fixing rods 6 and the screw 8 to pull out the inner side of the square groove 4, so that the card plate 7 is squeezed to the first spring 9, driving the card plate 7 to release the engagement with the corresponding bearing chamber slot, thereby facilitating disassembly. During installation, push the handle 27, and under the action of the first spring 9 pushing the card plate 7, drive the card plate 7 to be inserted into the inner side of the corresponding slots at the upper and lower ends of the bearing box. After the card plate 7 is inserted, the second spring 12 pushes the push plate 14, so that the card plate 7 is more tightly engaged with the slot, thereby facilitating quick disassembly and maintenance, reducing the usage rate of screws and nuts, thereby reducing the time wasted during disassembly, and improving the bearing box. The efficiency during disassembly is improved, and the phenomenon of construction delay is reduced. When the size of the mounting hole 3 is adjusted according to the bearing box, the knob 25 is turned to make the knob 25 drive the rotation of the left-side bidirectional screw 17, thereby making the left-side bidirectional screw 17 drive the left-side synchronous wheel 22 to rotate, and under the action of the synchronous belt 23, the rotation of the right-side synchronous wheel 22 is driven, thereby driving the rotation of the right-side bidirectional screw 17, so that the left and right bidirectional screws 17 simultaneously drive the upper and lower adjustment plates 18 to move relative to each other, thereby reducing the mounting hole 3. When contacting the bearing box, the push column 21 pushes the bearing box under the rebound push of the push spring 20, thereby increasing the tightness of the bearing box installation, facilitating the adaptation to bearing boxes of different diameters, thereby facilitating the installation of bearing boxes of different diameters, and increasing the adjustability of the mounting hole 3 in the large frame.
