Description

Technical Field

[0001] This invention relates to the field of symmetrical circular arc guide rail assembly processing and testing technology, specifically to a symmetrical circular arc guide rail assembly and its processing method. Background Technology

[0002] In the aerospace field, symmetrical circular arc guide pairs are key components in precision transmission systems. If their precision exceeds the tolerance, it will trigger a series of chain reactions, directly affecting the operational stability, reliability, and service life of the entire mechanical system.

[0003] Currently, the most common machining method for symmetrical arc guide rail pairs is single-piece machining. However, during single-piece machining, it is difficult to ensure that the relative positions of the two symmetrical arc guide rail surfaces and the fixed mounting surface are completely aligned. Therefore, a laser tracker is used for accuracy testing during subsequent installation. However, the laser tracker cannot provide accurate adjustment data for the installation and adjustment of symmetrical arc guide rail pairs, requiring repeated testing and adjustments. Furthermore, the investment cost of laser tracker equipment is high, making it unsuitable for frequent daily testing. Therefore, this is not an ideal method for machining symmetrical arc guide rail pairs.

[0004] Therefore, it is necessary to design a simple, cost-effective method for the combined machining and inspection of symmetrical circular arc guide pairs to solve the above problems. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing a symmetrical circular arc guide rail assembly and its processing method.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A method for machining a symmetrical circular arc guide pair assembly includes the following specific steps: S1: Place one side of the circular arc guide rail pair on the boring machine worktable and position it; S2: Place the symmetrical arc guide rail pair on the boring machine worktable and place it symmetrically with the arc guide rail pair on one side, so that the positions of one end of the two arc guide rail pairs are consistent; S3: Adjust the position of the circular arc guide rail pair on the symmetrical side until the other ends of the two circular arc guide rail pairs are in the same position.

[0007] The beneficial effects of this invention are as follows: During the processing, S1: Place one side of the arc guide rail pair on the boring machine worktable and position it; S2: Place the symmetrical side of the arc guide rail pair on the boring machine worktable and place it symmetrically with the arc guide rail pair on one side, so that the positions of one end of the two arc guide rail pairs are consistent; S3: Adjust the position of the symmetrical side of the arc guide rail pair until the positions of the other ends of the two arc guide rail pairs are consistent, which makes the processing convenient and the accuracy high.

[0008] The method of this invention is simple and reasonably designed, and can realize the simultaneous processing of two circular arc guide rail pairs to ensure that the relative positions of the circular arc guide rail surfaces and the fixed mounting surfaces of the two symmetrical circular arc guide rail pairs are completely consistent, with high precision. There is no need to use a laser tracker to detect the precision of the two symmetrical circular arc guide rail pairs in the future, which greatly reduces the cost.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, S1 specifically includes the following steps: using a dial indicator to position the arc guide pair by pressing one end face of the arc guide pair.

[0011] The advantages of adopting the above-mentioned further scheme are that the method is simple and the design is reasonable. The dial indicator is used to select two reference surfaces on one side of the arc guide pair for positioning, and the position of the arc guide pair is determined.

[0012] Furthermore, S2 specifically includes the following steps: using a dial indicator to initially position the two arc guide rail pairs by their end faces, until the positions of one end of the two arc guide rail pairs are consistent.

[0013] The advantages of adopting the above-mentioned further solution are that the method is simple and the design is reasonable. The dial indicator is used to perform preliminary positioning of the two arc guide rail pairs until the positions of one end of the two arc guide rail pairs are consistent, thereby realizing the rapid positioning of one end of the two arc guide rail pairs.

[0014] Furthermore, S3 specifically includes the following steps: S31: Install a slider on one side of the arc guide rail pair, place a dial indicator on the slider, and press the dial indicator head onto the guide rail surface of the arc guide rail pair on the symmetrical side. S32: Push the slider and record the changes in the dial gauge data during the pushing process; S33: Analyze the above data and adjust the position of the other end of the circular arc guide pair on the symmetrical side according to the above data, so that the positions of the other ends of the two circular arc guide pairs are consistent.

[0015] The advantages of adopting the above-mentioned further solution are that the method is simple and the design is reasonable. During the movement of the slider on one side of the arc guide pair, the dial indicator is used to detect the specific position of each part of the symmetrical side arc guide pair and record the relevant data. At the same time, the recorded data is analyzed and the specific position of the symmetrical side arc guide pair is adjusted in real time based on the analysis results.

[0016] Furthermore, S3 specifically includes the following steps: S34: Repeat S32 and S33 until the change in the above data during the slider pushing process is less than 0.01.

[0017] The advantages of adopting the above-mentioned further solution are that the method is simple and the design is reasonable. By repeatedly performing S32 and S33, the specific position of the symmetrical side arc guide pair is continuously adjusted until the change in the above data is less than 0.01, the accuracy is greatly improved, and the position of the two arc guide pairs is consistent.

[0018] Furthermore, S3 is followed by S4: Milling is performed on the sides of the two arc guide rail pairs that are far apart from each other to form the mounting surface of the arc guide rail pairs, so that the two mounting surfaces are coplanar.

[0019] The advantages of adopting the above-mentioned further solution are that the method is simple and the design is reasonable. The side of the two arc guide rail pairs that is far apart from each other is milled to form the mounting surface of the arc guide rail pairs, ensuring that the two mounting surfaces share a common center, thereby ensuring that the two arc guide rail pairs can be coplanar during installation.

[0020] Furthermore, before S1, there is also S0: assembling the two circular arc guide rail pairs.

[0021] The advantages of adopting the above-mentioned further solution are that the method is simple, the design is reasonable, and the two arc guide rail pairs are pre-assembled, which facilitates the subsequent processing of the two arc guide rail pairs.

[0022] Furthermore, S0 specifically includes the following steps: S01: Place two symmetrical guide rail seats symmetrically on a lathe, and machine mounting grooves on the sides of the two guide rail seats that are close to each other. S02: Install the two guide rails into the two mounting slots respectively, and install sliders on the two guide rails respectively.

[0023] The advantage of adopting the above-mentioned further solution is that during the processing, two mounting slots are first machined on the two guide rail seats, and then the two guide rails are installed in the two mounting slots, which makes assembly convenient and highly accurate.

[0024] The present invention also relates to a symmetrical arc guide rail assembly, which is manufactured by the processing method of the symmetrical arc guide rail assembly described above. It includes two symmetrically distributed arc guide rail assemblies, each of which includes a guide rail seat and a guide rail. The two guide rails are respectively mounted on the two guide rail seats, and sliders are slidably mounted on the two guide rails.

[0025] The beneficial effect of adopting the above-mentioned further solution is that the present invention also provides a symmetrical arc guide rail pair assembly. The symmetrical arc guide rail pair assembly has a simple structure and reasonable design. The two symmetrical arc guide rails can control the relative position of the arc guide rail surface and the fixed installation surface to be completely consistent. There is no need to use a laser tracker for accuracy detection during subsequent installation. It has high accuracy and low cost.

[0026] Furthermore, mounting grooves are provided on the sides of the two guide rail seats that are close to each other, and the two guide rails are installed in the two mounting grooves respectively.

[0027] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. The guide rail is installed by using two mounting slots designed on the guide rail base, which ensures the accuracy of the guide rail installation. This ensures that the relative position of the two symmetrical arc guide rail pairs can be completely consistent with the fixed mounting surface, resulting in high accuracy. Subsequently, there is no need to use a laser tracker to detect the accuracy of the two symmetrical arc guide rail pairs, which greatly reduces the cost. Attached Figure Description
