The driving wheel 35 is installed on the output end of the grinding head driver 34, and the grinding head driven wheel 36 is installed on the second extended end of the main shaft 32, so as to realize the purpose of the grinding head driver 34 driving the main shaft 32 from a distance; preferred Yes, the grinding head driving wheel 35 and the grinding head driven wheel 36 are a sprocket or a pulley, and correspondingly, the grinding head transmission part is a chain or a transmission belt. The second is that the output end of the grinding head driver 34 is equipped with a grinding head driving gear, and the second extended end of the main shaft 32 is equipped with a grinding head driven gear that is meshed with the grinding head driving gear, so that the grinding head driver 34 The purpose of driving the second extension end of the main shaft 32 to rotate more precisely.

Simultaneously, the rotation driving mechanism 60 is installed on the upper and lower mounting frames 12, and the rotation driving mechanism 60 drives the rotating seat plate 70 to rotate in the vertical plane, and the rotating seat plate 70 drives the emery wheel 31 to do matching in the vertical plane. The rotation of the saw teeth 210 of the disc cutter 200; in order to make the rotating seat plate 70 in a locked state when it does not need to rotate relative to the upper and lower mounting brackets 12, to prevent the grinding wheel 31 from sawing the disc cutter 200 on the load shifting gear mechanism 20 210 is processed because of the running of the rotating seat plate 70 relative to the upper and lower mounting frames 12 and affects the quality of the teeth opening 210 of the disc cutter 200, so a second mechanism is provided between the upper and lower mounting frame 12 and the rotating seat plate 70. The actuating mechanism 15, the second braking mechanism 15 selectively prohibits or allows the rotation of the rotating seat plate 70 relative to the upper and lower mounting frames 12 in the vertical plane. Specifically, the second brake mechanism 15 includes a lever 151 , a brake block 152 , a fixing base 153 and a second linear driver 154 for linear telescopic movement. The fixed seat 153 is fixed on the rotating seat plate 70, the lever 151 is pivotally connected to the fixed seat 153 and separates the first pivot part 1511 and the second pivot part 1512 relative to the pivot point of the lever 151 and the fixed seat 153, and the second straight line The driver 154 is installed on the fixed seat 153 and drives the first pivot part 1511 to pivot. The brake block 152 is assembled on the second pivot part 1512 and corresponds to the upper and lower mounting frames 12. The side walls of the arc-shaped rack 61 described are opposite to each other, so that the linear telescopic movement of the second linear driver 154 drives the brake block 152 through the lever 151 to prevent or allow the rotation of the rotating seat plate 70 relative to the upper and lower mounting brackets 12, In order to simplify the structure of the second braking mechanism 15 and reduce the cost.

Furthermore, the rotation drive mechanism 60 includes an arc-shaped rack 61 installed on the upper and lower mounting frames 12, an engaging gear (not shown) that is installed on the rotating seat plate 70 and meshes with the arc-shaped rack 61 for transmission, and Drive the rotation driver 62 that meshing gear rotates, and the circle center of circular arc tooth bar 61 is positioned on the horizontal pivot axis (being the axis line of horizontal pivot shaft 65), and rotation driver 62 is installed on the rotating seat plate 70, and emery wheel 31 is opposite The grinding point formed when the serrated teeth 210 of the disc cutter 200 is ground is located on the center of circle of the arc-shaped tooth bar 61. Preferably, the end face 311 of the emery wheel 31 is on the saw teeth 210 of the disc cutter 200. The grinding point formed during grinding is located on the center of circle of the arc-shaped tooth bar 61, to expand the grinding effect of the grinding wheel 31 on the saw teeth 210 of the disc cutter 200, and also to make the rotary driver 62 pass through the meshing gear and the arc-shaped tooth. The cooperation of the bar 61 realizes the purpose of the precise rotation of the rotating seat plate 70 relative to the upper and lower mounting frames 12 . Preferably, in order to reduce the rotating speed of the rotary driver 62 and provide more powerful output power, so a reduction box 63 is installed between the rotary driver 62 and the meshing gear, the rotary driver 62 is connected with the input shaft of the reduction box 63, and the meshing gear is installed on On the output shaft of the reduction box 63; in order to make the rotation of the rotating seat plate 70 more precise, an auxiliary motor 64 is also connected on the horizontal pivot shaft 65.

Compared with the prior art, with the coordination of the first driving mechanism 40, the second driving mechanism 50, the rotating driving mechanism 60 and the rotating seat plate 70 of the present utility model, under the action of the first driving mechanism 40, Drive the saw teeth 210 of the disc cutter 200 on the load shifting mechanism 20 to move to match the grinding wheel 31, and under the action of the second drive mechanism 50, drive the grind wheel 31 to move to match the saw teeth 210 of the disc cutter 200 , under the action of the rotating drive mechanism 60, the grinding wheel 31 is driven to rotate in the vertical plane to match the saw teeth 210 of the disc cutter 200, so that the grinding wheel 31 automatically matches the shape of the saw teeth 210 of the disc cutter 200 Matching, and then the saw teeth 210 of the disc cutter 200 are toothed by the grinding wheel 31. Therefore, the gear cutting machine 100 for the disc cutter of the present utility model is used to perform automatic gear cutting on the saw teeth 210 of the disc cutter 200 purpose, thereby reducing the burden on the operator. Just because the grinding wheel 31 actively matches the shape of the saw teeth 210 of the disc cutter 200 through the coordination of the rotating drive mechanism 60 and the second drive mechanism 50, and actively matches the saw teeth 210 of the disc cutter 200 reciprocating movement, so that the grinding wheel 31 processes the saw teeth 210 of the disc cutter 200 as an active feeding method, thus avoiding the traditional way of using the saw teeth 210 of the disc cutter 200 as the feeding method. The saw teeth 210 of the disc cutter 200 are always in a state of tightly pressing the grinding wheel 31 , correspondingly, the loss of the grinding wheel 31 is reduced.

What is disclosed above is only a preferred example of the utility model, which certainly cannot limit the scope of rights of the utility model. Therefore, the equivalent changes made according to the claims of the utility model still belong to the scope covered by the utility model.
