The lower end of the vertical plate 2 is fixed with a horizontal bottom plate 23, and the bottom plate 23 and the workbench 1 are fixed together through a plurality of bolts.

It is worth noting that in order to reduce friction force, bearings are mounted between the end of the lead screw 4 and the vertical plate 2, and bearings are mounted between the central shaft 11 of the small chain wheel 7 and the rectangular block 3; the second motor 21 and the third motor 22 are both servo motors with brake function; a channel 24 is fixed at the lower end of the top plate 5, a chain meshed with the small gear passes through the channel 24, and a tension pulley is arranged at the other side of the chain to ensure that the chain is in a horizontal state and is meshed with the small gear 7 at any time.

When the tool is used, a machined workpiece is firmly fixed on the workbench 1, at the moment, the first motor and the hydraulic cylinder 12 are started, the cutter 13 at the lower end is contacted with the workpiece, then the second motor 21 is started, the third motor 22 is not moved, the second motor 21 drives the second gear 20 to rotate, so that the two first gears 19 simultaneously rotate, the first gears 19 rotate to drive the screw rod 4 to rotate, the screw rod 4 rotates to drive the rectangular block 3 to move leftwards and rightwards along the screw rod 4, at the moment, the chain is not moved, the rectangular block 3 moves leftwards and rightwards to drive the small chain wheel 7 to roll along the chain, at the moment, the chain and the small chain wheel 7 act as a gear rack, the central shaft 11 of the small chain wheel 7 drives the sliding cylinder 10 to rotate by taking the central shaft 11 as the center, the sliding cylinder 10 enables the circular plate 8 to rotate by taking the central shaft 11 as the center through the screw rod 9, the circular plate 8 rotates, thereby effecting the engravings of the tool 13 on the surface of the workpiece.

According to the process, as shown in the attached drawing 1, a group b is a normal cycloid curve, wherein a group b is a standard cycloid curve, a short cycloid curve and a long cycloid curve from top to bottom in sequence, in combination with the method, the distance L from the lower end cutting edge of the cutter 13 to the axis of the central shaft 11 of the small sprocket 7 is set, half of the nominal diameter of the worm gear 15 is set to be R, when L = R, the track of the cutter 13 on the workpiece is the standard cycloid curve, when L < R, the track of the cutter 13 on the workpiece is the short cycloid curve, and when L > R, the track of the cutter 13 on the workpiece is the long cycloid curve.

In the above process, the trajectory of the tool 13 on the workpiece is a normal cycloid, for example, the group b straight line in fig. 1, if the curvature and density of the trajectory need to be changed, that is, the distance spanned by one arch of the trajectory is changed, at this time, the third motor 22 is started, the third motor 22 rotates to drive the small sprocket 7 to rotate through the large sprocket 6 and the chain, and at the same time, the lead screw 4 drives the central shaft 11 of the small sprocket 7 through the rectangular block 3 to roll the small sprocket 7 along the chain, and the two are overlapped to increase or decrease the span of each arch, for example, the group a in fig. 1 is the trajectory after the span of each arch is increased, and the group b in fig. 1 is the trajectory after the span of each arch is decreased. When the distance of the left and right movement of the rectangular block 3 is equal to the distance of the movement of the chain and the direction is opposite in the same time, the path engraved on the surface of the workpiece by the cutter 13 is a straight line.

The camber of the path of the tool 13 on the surface of the workpiece is adjustable by the following specific steps: by rotating the screw 9 on the circular plate 8, the relative position between the slide cylinder 10 and the circular plate 8, namely the distance between the lower end of the cutter 13 and the central shaft 11 of the small chain wheel 7, can be changed by rotating the screw 9, so that the arch height of the carving track can be adjusted.

The invention is also suitable for circular tracks, and the specific method is that the third motor 22 rotates, and the second motor 21 is fixed and does not rotate, namely the large chain wheel 6 drives the small chain wheel 7 to rotate through a chain but the screw rod 4 does not rotate, the worm 14 rotates to enable the cutter 13 to rotate around the central shaft 11 of the small chain wheel 7, a circular track is finally formed, and the adjustment of the radius of the circular track can be realized by adjusting the position of the sliding cylinder 10 on the screw rod 9. On the basis, the conical or circular truncated cone-shaped surface can be engraved or modified with textures, specifically, the worm 14 is rotated manually, the worm 14 drives the worm wheel 15 to rotate, the worm wheel 15 rotates to drive the movable plate 16 to swing up and down, when the movable plate 16 swings to a specific position, the rotation is stopped, at this time, the angle of the movable plate 16 is fixed, and meanwhile, the engraving angle of the cutter 13 is also fixed.

The invention has the outstanding advantages and remarkable progress that:

1. the chain wheel structure and the screw rod 4 nut structure are adopted to meet the requirement of private customization in house construction and decoration, wherein the small chain wheel 7 and the chain replace a gear rack structure under specific conditions, the channel 24 can provide enough supporting force for the chain, the small chain wheel 7 and the chain are prevented from being separated from each other, the track of the cutter 13 can be flexibly adjusted, the screw rod 4 can enable the rectangular block 3 to stably move, the cutter 13 can stably move along the specific track, vibration is reduced, the screw rod 4 nut structure can bear larger torque, and manual labor is reduced.

2. The large chain wheel 6 in the invention directly influences the moving speed of the chain to the span of each arch formed by the track stroked by the cutter 13, and the large chain wheel 6 can also be rotated by a manual rocking handle to manually rotate the large chain wheel 6, so that the span of one arch is increased or reduced in a certain specific area, but workers need quite abundant experience, otherwise, the large chain wheel deviates from the preset track and even the workpiece is scrapped.

3. The invention is suitable for carrying and site construction, can be manufactured in real time according to site requirements, greatly saves processing cost, is beneficial to improving construction efficiency, has wide applicability, is convenient for carrying and transferring and is easy to popularize.
