In the process of cutting the linear guide 10, the linear guide 10 can be clamped by the automatic centering vise to ensure its accurate position and improve the cutting accuracy. The saw blade 3 in the utility model is arranged above the automatic centering vise. The saw blade 3 in the utility model is used as a cutting tool for cutting the linear guide 10 and is driven by an externally arranged saw blade 3 driving device (not shown in the figure). The saw blade 3 driving device can adopt any one of an electric driving device or a pneumatic driving device. Specifically, the electric driving method is: connected to the saw blade 3 through an electric motor, and the saw blade 3 is driven to rotate by electric energy to cut. The pneumatic driving method is: using a pneumatic motor or a cylinder to provide driving force, and the saw blade 3 is operated by compressed air to achieve the cutting action.

[0043] The positioning mechanism 2 in the utility model includes a positioning plate 21, a positioning pin 22 and a slider 23. The positioning plate 21 is fixedly connected to one side of the nut seat 17, and the slider 23 is fixedly connected to the bottom of the positioning plate 21.

The positioning pin 22 is used to position the linear guide 10. When the linear guide 10 is processed, the through hole opened on the linear guide 10 can be inserted into the positioning pin 22, so as to position the linear guide 10.

[0044] The pushing mechanism 8 in the utility model includes a driving cylinder 81 and a pushing plate 82. The driving cylinder 81 is fixedly connected to the material storage rack 9. The output end of the driving cylinder 81 and the pushing plate 82 are mutually driven and connected. The driving cylinder 81 provides the pushing plate 82 with movement force. When the saw blade 3 completes the cutting of the linear guide rail 10, the driving cylinder 81 can drive the pushing plate 82 to push the processed linear guide rail 10 to the material storage tray 6.

[0045] Working principle: The cutting of the linear guide rail 10 generally requires two cuts. Figure 5 This is the first cutting diagram to ensure the end distance size. Figure 6 This is a schematic diagram of the second cut. The second cut ensures the total length. At present, the whole material of our company's linear guide 10 is 4000mm long, the hole spacing is 60mm, and the end distance of the whole material is 20mm at both ends. Insert the leftmost hole of the linear guide 10 into the positioning pin 22, and the initial position of the center of the positioning pin 22 is set to 0. The distance between the center of the positioning pin 22 and the left end of the saw blade 3 is a fixed value of 3990mm. At this time, the distance between the saw blade 3 and the rightmost hole of the workpiece is 30mm. According to the length requirement of the linear guide 10, enter the left end distance value and the total length in the display screen, and the system will control the servo motor 11 to move forward the corresponding distance (when cutting the total length, the moving distance needs to add the thickness t of the saw blade 3). Since the hole spacing of the linear guide 10 is 60mm, when the cutting end distance is greater than 30mm, after the first cut, the other end is less than 30mm, and it needs to move 30mm + hole spacing (60mm); when the cutting end distance is less than 30mm, it is only necessary to move the input end distance value. When the cutting end distance is 30mm, the end distance does not need to be moved. At this time, the end distance value after cutting is slightly less than 30mm (half the thickness of the saw blade 3). This error is within the tolerance range required by the linear guide 10. Since the end distance of the linear guide 10 is 20mm, the end distance +10mm has been set in advance in the system when the first cut is made. The centers of the two pneumatic automatic centering vises are in the same straight line as the center of the locating pin 22. After each cut is completed, the linear guide 10 moves forward and is clamped, and the center of the linear guide 10 does not change. In addition, by cutting other linear guides 10 of the same width and replacing the locating pins 22, linear guides 10 of other specifications can be processed. The cut material head falls into the discharge hole 91 as the linear guide 10 moves.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents.
