In the utility model, by setting the universal turntable 61 and its driving device universal rotation drive device 62, the workpiece processing mechanism 5 fixed on the universal turntable 61 can realize the overall rotation, and then adjust the working head 53 of the workpiece processing mechanism 5 to work. The angle is convenient for processing operations such as cutting or grinding, and it can be adapted to the processing of various shapes of stone workpieces to be processed.

Embodiment two

As shown in Figures 1-6, the difference between this embodiment and Embodiment 1 is that this embodiment is additionally equipped with an infrared profiling device (not shown in the figure). The infrared profiling device includes a profiling control part and a controller. The left side end of beam arm 22 is provided with formwork track, and this formwork track is clamped with profiling formwork, is stone material formwork among the utility model, and profiling formwork 72 is arc lines. The curvature of the arc line matches the curvature of the workpiece to be processed. The arc-shaped lines are arranged horizontally or vertically, and the arc of the arc-shaped lines is bent upwards or downwards. In this embodiment, it is preferably bent upwards. The profiling control part 71 adopts an infrared receiver, and the output terminal of the profiling control part 71 is connected to the corresponding input terminal of the controller. The corresponding control ends of the first longitudinal power device 25 , the transverse power device, the universal rotation drive device 62 and the motor drive device 55 are connected to the corresponding output ends of the controller. And the profiling template is profiled through the profiling control part with the electro-optic tracking head. The controller is used for analyzing the profiling information of the transmitted profiling template, and controlling the working head 53 to perform profiling processing on the workpiece to be processed. The rotation of the universal turntable 61 can drive the universal rotation of the working head 53, thereby realizing the processing of the curved surface. In the present utility model, the infrared profiling device is a conventional profiling device, which will not be described in detail here. The workpiece processed by the infrared profiling device has high processing accuracy.

It should be noted that, in addition to the above-mentioned infrared profiling device, the utility model can also use a video analysis profiling device and a profiling device for manually inputting processing component data. The video analysis profiling intercepts the contour line of the profiling template according to the video screenshot, and performs profiling through the contour line.

Embodiment three

The difference between this embodiment and the first embodiment lies in the structure of the workpiece processing mechanism 5 .

As shown in FIGS. 1-7 , in this embodiment, the workpiece processing mechanism 5 includes a spindle box 51 and a processing arm 52 for installing a working head. One end of the processing arm 52 is detachably mounted on the output end of the headstock 51 . towards the workpiece to be machined. A working head 53 is installed on the other end of the processing arm 52 , and the other end of the processing arm 52 is provided with a mounting portion 54 , and the working head 53 is detachably mounted on the other end of the processing arm 52 through the mounting portion 54 . The mounting part 54 matches the working head 53 , and the shape and size of the mounting part 54 can be adaptively adjusted according to the difference of the working head 53 . For example, it may be in the shape of a rod, a tube, or a plate. The working head 53 can be a grinding tool or a cutting knife or the like. Corresponding to the mounting part 54, the working head 53 is provided with a mounting hole 531, the mounting hole 531 is a "T" hole or an inverted "T" hole, and its head is a concave ring groove, which is convenient for the end of the mounting part 54. Perhaps the head of the locking part between the mounting part 54 and the working head 53 sinks, avoiding the traditional technology, the end of the mounting part 54 or the head of the locking part protrude from the working surface of the working head 53 and affect the Stone grinding and processing problems. The mounting part 54 and the working head 53 can be detachably fixed together by means of a protruding ring and a slot, bolts and nuts, and a magnetic attraction device. As shown in Figure 7, for the benefit of fixing the bolts and nuts, a plurality of inverted "T"-shaped mounting holes 531 are provided on the working head. After locking, the heads of the bolts sink into the concave ring grooves of the mounting holes 531 , does not affect the flatness of the working surface when the working head 53 is in use.

The bottom of the spindle box 51 is provided with an external thread, and one end of the processing arm 52 is provided with an internal thread matching the external thread. The spindle box 51 and the processing arm 52 are quickly loaded and unloaded through the cooperation of the internal and external threads. It should be noted that, in the present utility model, in addition to the cooperation of the above-mentioned internal and external threads, the detachable connection between the spindle box 51 and the processing arm 52 can also be detachable such as bolts and nuts, pin sockets or magnetic suction. a fixed way.

During use, when processing different stone materials, different working heads 53 can be selected by replacing the processing arm 52 with the working head 53, without frequent and cumbersome processing requirements for different stone materials or different processing techniques The replacement of the working head 53 can significantly improve the working efficiency.
