Description

Technical Field

[0001] This invention relates to the field of cutting technology, specifically a cutting correction method for guide rail cutting equipment. Background Technology

[0002] Guide rails, also known as linear guides or linear slides, are an upgraded version of linear bearing brackets used in linear reciprocating motion applications. They have a higher rated load than traditional linear bearings and can withstand a certain amount of torque, enabling high-precision linear motion under high load conditions.

[0003] The guide rail needs to be cut during the production process. The guide rail has evenly spaced through holes. When cutting the guide rail into multiple finished products, these through holes allow for correction and positioning of the guide rail. Current guide rail cutting correction methods typically use a drive module and positioning pins. The positioning pins are mounted on the drive module, which drives the positioning pins to insert into the through holes of the guide rail and moves the guide rail forward. After cutting one finished product, the movement continues. This means that regardless of how many times a guide rail is cut, it is only corrected once. Although the positioning pins have a certain correction effect when inserted into the through holes, small errors still exist. This results in errors in the position of the through holes of the finished products, even if the length of the cut product is correct. Specifically, the initial length of the guide rail is 4 meters. Small errors occur after each movement and cut, and these accumulated errors become increasingly larger, leading to larger errors in the position of the through holes in subsequent cut products. Therefore, the existing guide rail cutting correction method needs further improvement and optimization. Summary of the Invention

[0004] This invention discloses a cutting correction method for guide rail cutting equipment to solve the technical problem of large errors caused by error accumulation.

[0005] To address the aforementioned technical problems, the present invention proposes the following optimized technical solutions: A cutting correction method for a guide rail cutting device includes step S3, performing correction and positioning once before cutting each finished product.

[0006] Furthermore, step S3 is preceded by step S1, where step S1 sets the moving displacement of the moving mechanism according to the required length of the finished product.

[0007] Furthermore, there is a step S2 between step S1 and step S3, in which the positioning position of the correction mechanism is set according to the guide rail end distance.

[0008] Furthermore, step S1 includes a first method: correcting and positioning the guide rail while moving it.

[0009] Furthermore, step S1 includes a second method: correcting and positioning the guide rail before moving it.

[0010] Furthermore, step S1 includes a third method: correcting and positioning the guide rail after it has been moved.

[0011] Furthermore, after step S3, there is step S4, in which the cutting mechanism cuts the guide rail.

[0012] Furthermore, in the first method of step S1, the positioning pin is inserted into the through hole of the guide rail through the drive module and drives the guide rail to move forward.

[0013] Furthermore, in the second method of step S1, the positioning pin is inserted into the through hole of the guide rail to correct and position the guide rail, and then the moving mechanism moves the guide rail according to the set displacement.

[0014] Furthermore, in the second method of step S1, the moving mechanism moves the guide rail according to the set displacement, and then the positioning pin is inserted into the through hole of the guide rail to correct and position the guide rail.

[0015] The present invention has the following advantages over the prior art: The cutting correction method for guide rail cutting equipment provided by this invention corrects the deviation once before each finished product is cut. That is, each finished product is corrected once before it is cut out, which eliminates the cumulative error and avoids the cumulative error of subsequent finished products from becoming larger and larger, which leads to the distance error between the through hole position of the guide rail and the cutting surface becoming larger and larger, thus greatly improving the accuracy of the guide rail.

[0017] Figure 2 This is a block diagram of step 3 of the present invention. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] The term "finished product" refers to a section of guide rail cut to the required length; this section of guide rail is the finished product. During the production stage, a 4-meter-long guide rail is typically produced, and then this 4-meter-long guide rail is cut into multiple finished sections.

[0020] The distance between the through hole of the guide rail and the cutting surface is the end distance of the guide rail.

[0021] See Figure 1-2 A cutting correction method for a guide rail cutting device includes step S3, which involves correcting and positioning the guide rail once before cutting each finished product. Specifically, after the initial correction and cutting, the guide rail is moved forward and corrected (the order of movement and correction is not limited; they can be performed simultaneously, either by moving first and then correcting, or by correcting first and then moving), and then cutting is performed. After cutting, the guide rail is moved forward and corrected again, and then cut, and this cycle is repeated until one guide rail is cut.

[0022] In this embodiment, step S1 precedes step S3. In step S1, the moving displacement of the moving mechanism is set according to the required length of the finished product. The position of the moving mechanism is the position used to drive the guide rail to move.

[0023] In this embodiment, there is a step S2 between step S1 and step S3. Step S2 sets the positioning position of the correction mechanism according to the guide rail end distance. For example, if the guide rail end distance is 15cm, the positioning pin of the correction mechanism is positioned so that it can be inserted into the through hole of the guide rail with an end distance of 15cm. That is, when there is an error in the guide rail, since the positioning pin of the correction mechanism is inserted into the through hole of the guide rail with an end distance of 15cm, the tapered part of the positioning pin has a correction effect on the guide rail, so that the guide rail can correspond to the position of the through hole of the guide rail with an end distance of 15cm, thus eliminating the end distance error.

[0024] Here, the end of the positioning pin has a tapered structure.

[0025] In this embodiment, step S1 includes a first method: simultaneously moving the guide rail and correcting its positioning. In this first method, a positioning pin is inserted into the through-hole of the guide rail via a drive module, causing the guide rail to move forward. The positioning pin has a corrective function when inserted into the through-hole, and the drive module's movement of the positioning pin causes the guide rail to move forward. Therefore, correction and movement occur simultaneously; that is, the moving mechanism and the correction mechanism are the same mechanism. Specifically, the drive module drives the positioning pin to insert into the through-hole of the guide rail and moves the guide rail forward, then cuts. After cutting, the drive module again drives the positioning pin to insert into the through-hole of the guide rail and moves the guide rail forward, repeating this cycle until cutting is complete.

[0026] To further clarify, the aforementioned drive module includes an X-axis drive module and a Y-axis drive module. The Y-axis drive module is mounted on the X-axis drive module, and the positioning pin is mounted on the Y-axis drive module. The X-axis drive module is used to drive the positioning pin to move along the axial direction of the guide rail, and the Y-axis drive module is used to drive the positioning pin to move closer to or further away from the guide rail to insert into or disengage from the guide rail through hole. Here, the structures of the X-axis drive module and the Y-axis drive module can be selected in various ways to achieve the purpose of driving the positioning pin to move. For example, they can all be conventional motor + lead screw structures, or cylinder drives, or linear drive structures such as linear guide rails.

[0027] In this embodiment, step S1 includes a second method: correcting and positioning the guide rail before moving it. The second method of step S1 involves inserting a positioning pin into the through-hole of the guide rail to correct and position it. Then, the moving mechanism moves the guide rail according to the set displacement. This moving mechanism is not the same as the correction mechanism. The correction mechanism has a structure with a positioning pin. The positioning position of the positioning pin is set according to the end distance of the guide rail. The moving mechanism can be used by clamping the guide rail to move it, or by directly pushing it, or by any other method that can move the guide rail. First, the positioning pin is inserted into the through-hole of the guide rail for correction. The cutting mechanism cuts away the excess waste material caused by the end distance error. Then, the moving mechanism moves the guide rail and performs another cut, resulting in the finished product.

[0028] In this embodiment, step S1 includes a third method: correcting and positioning the guide rail after moving it. The second method of step S1 involves a moving mechanism moving the guide rail according to a set displacement, and then a positioning pin being inserted into the through hole of the guide rail to correct and position it. The moving mechanism can be a clamping mechanism to move the guide rail, a direct pushing mechanism, or any other mechanism capable of moving the guide rail. The correction mechanism is a structure with a positioning pin, and the positioning position of the positioning pin is set according to the guide rail end distance. First, the guide rail is moved by the moving mechanism, and the cutting mechanism cuts away excess waste material that causes deviation due to error. Then, the positioning pin is inserted into the through hole of the guide rail for correction, and then cutting is performed again, resulting in the finished product.

[0029] To further explain, in both the second and third methods of step S1, the positioning pin is inserted into the Y-axis drive module. The Y-axis drive module is used to drive the positioning pin to move closer to or away from the guide rail to insert into or disengage from the guide rail through hole. The moving mechanism includes an X-axis drive module and a clamping assembly. The moving assembly is disposed on the clamping assembly and is used to clamp the guide rail. The moving assembly is used to drive the clamping assembly to move along the axial direction of the guide rail, thereby causing the guide rail to move forward.

[0030] In this embodiment, step S3 is followed by step S4, in which the cutting mechanism cuts the guide rail.
