Description

Technical Field

[0001] The utility model belongs to the technical field of guide rail processing, and more specifically, particularly relates to a linear guide rail cutting device. Background Art

[0002] According to the actual size, installation space and functional requirements of the production equipment, the linear guide rail needs to be cut to precise length to ensure the smooth operation of the equipment. The guide rail cutting machine is a commonly used cutting equipment for cutting linear guide rails. The existing guide rail cutting machine is generally composed of a cutting machine frame, a cutting mechanism, a clamping mechanism and a rotating roller for placing the guide rail.

[0003] The utility model with the existing patent application number CN201921917832.4 discloses a grinding guide rail cutting machine, including a working platform, a guide rail clamping device and a guide rail cutting device. The guide rail clamping device includes a limit stop bar, a pressure block and a pressure block driving assembly. The pressure block driving assembly drives the pressure block to press the guide rail to be processed onto the limit stop bar; the guide rail cutting device includes a horizontal slide rail, a ram, a column, a reciprocating drive assembly, a vertical slide rail, a lifting bracket, a lifting drive assembly, a saw blade and a saw blade driving assembly. When cutting the guide rail to be processed, the reciprocating drive assembly drives the ram to reciprocate on the horizontal slide rail, and the lifting drive assembly drives the lifting bracket to move downward at a constant speed on the vertical slide rail; thereby, the motion trajectory of the saw blade is similar to simple harmonic motion, making it easier to cut extra-large workpieces and workpieces with high hardness; during the reciprocating cutting process, the saw blade will not be stuck due to excessive friction, nor will it be broken and damaged due to overheating and brittleness, and the cutting surface of the workpiece will not be burned due to overheating.

[0004] Based on the above, in order to prevent the sparks generated by the friction between the guide rail and the blade during the cutting process from splashing onto the surrounding personnel, the guide rail cutting machine is usually equipped with a protective cover hinged at the cutting position. Each time a section of the guide rail is cut, the protective cover needs to be opened, and after the cut guide rail is taken out, the remaining guide rail is moved to the right to the appropriate position, and then the protective cover is closed before the next section of the guide rail can be cut. This operation is very cumbersome and greatly reduces the cutting efficiency of the guide rail. Utility Model Content

The entire operation process no longer requires opening the protective cover, which greatly simplifies the operation steps.

[0039] Secondly, each time the clamping plate clamps or releases the guide rail, it will drive the two leftmost second rotating rollers to rotate through the driving assembly, thereby effectively preventing the cut guide rail from being stuck between the leftmost second rotating rollers, allowing the cut guide rail to slide smoothly along the multiple second rotating rollers.

[0040] The utility model enables the guide rail to be cut after it contacts the left side of the resistance plate. When cutting guide rails of the same length, the position of the guide rail can be determined without opening the protective cover, which greatly improves the cutting efficiency of the guide rail. When the clamping plate moves back and forth, it drives the two leftmost second rotating rollers to rotate, ensuring that the cut guide rail can automatically fall into a container prepared in advance along the multiple second rotating rollers.

[0064] Among them, the automatic collection components also include:

[0065] The scale marks 7 are provided in multiple pieces, and the multiple scale marks 7 are dispersedly fixedly connected to the cutting machine body 1. The effect brought about is that the distance between the left side of the contact plate 601 and the blade in the cutting box 2 can be clearly observed through the multiple scale marks 7.

[0066] Among them, the automatic collection components also include:

[0067] A second rotating roller 8, wherein the second rotating roller 8 is provided in a plurality of pieces, and the plurality of second rotating rollers 8 are rotatably connected in the cutting machine body 1 in a dispersed manner;

[0068] The buffer pad 801 is provided with a plurality of pieces, and the plurality of buffer pads 801 are dispersedly and fixedly connected to the outside of the plurality of second rotating rollers 8.
