[0001] The utility model relates to the field of guide rail production detection, in particular to a guide rail detection fixture. Background Art

[0002] The guide rail inspection fixture is an important tool for precise measurement and inspection during the guide rail production process or after installation. It is a device specially designed to detect various parameters of the guide rail. It ensures that the accuracy, quality and performance of the guide rail meet the design requirements.

[0003] The guide rail inspection fixture includes a base for providing a stable support platform to ensure the stability of the fixture during the inspection process, a clamping device to ensure that the guide rail does not move or deform during the inspection process and ensure the accuracy of the measurement results, and a measuring element for actually measuring various parameters of the guide rail.

[0004] Existing guide rail inspection fixtures generally fix the guide rails through clamping handles, fixing blocks, bolts and other components. During use and observation, it was found that when the device fixes guide rails of different sizes, the bolts need to be removed, which makes the fixing operation more cumbersome and increases the working time required for the fixture to detect and fix guide rails of different sizes.

At the same time, by fixing the rubber block to the inner end of the support rod, deformation of the guide rail caused by excessive squeezing of the guide rail by the fixture can be reduced during the clamping process.

[0012] Preferably, a cleaning block is slidably connected to the fixed plate; the cleaning blocks are arranged in a corresponding group, and the dust attached to the surface of the air outlet can be cleaned by sliding the cleaning block, thereby reducing the clogging of the air outlet due to dust accumulation.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Specific examples are given below.

[0026] like Figures 1 to 6 As shown, a guide rail detection fixture described in an embodiment of the present invention includes an operating table 1, and multiple groups of limit blocks 11 are fixed to the top of the operating table 1; multiple limit holes 12 are opened on the limit blocks 11; a support rod 13 is slidably connected inside the limit holes 12; multiple first springs 14 are fixed to the side walls of the limit blocks 11; the support rod 13 is located inside the first spring 14; the end of the first spring 14 is fixedly connected to a rubber block 15; the rubber block 15 and the end of the support rod 13 are in a fixed relationship; the other end of the support rod 13 is fixedly connected to a pull rod 16; a conveyor belt 17 is installed on the top of the operating table 1; a detection component 18 is provided on the top of the operating table 1; when working, the pull rod 16 is pulled first, and the movement of the pull rod 16 drives the support rod 13 to move, and the support rod 13 drives The rubber block 15 moves, and under the action of the first spring 14, the rubber block 15 moves to the specified position, and the guide rail to be inspected is placed on the conveyor belt 17. Then the pull rod 16 is released, and under the action of the first spring 14, the rubber block 15 clamps the guide rail to be inspected, and finally the guide rail can be inspected by the detection component 18; by fixing the first spring 14 on the inner wall of the limit block 11 and fixing the rubber block 15 on the inner end of the support rod 13, the guide rail to be inspected can be clamped, and guide rails of different sizes can be clamped and fixed, reducing the working time required for fixing guide rails of different sizes. At the same time, by fixing the rubber block 15 on the inner end of the support rod 13, the deformation of the guide rail caused by excessive squeezing of the clamp on the guide rail can be reduced during the clamping of the guide rail.

[0027] like Figures 2 to 6 As shown, the detection assembly 18 includes a slide 2; the slide 2 is located on the top of the operating table 1; a linear motor 21 is installed inside the slide 2; the output end of the linear motor 21 is fixedly connected to a support arm 22; a scale column 23 is fixedly connected to the middle of the support arm 22; a second spring 24 is fixedly connected to the bottom of the scale column 23; a detection box 25 is fixedly connected to the bottom of the second spring 24; the scale column 23 and the detection box 25 are connected through the second spring 24; the detection box 25 is a hollow structure; the second spring 24 is located inside the detection box 25; the bottom of the detection box 25 is rotatably connected to a roller 26, which places the guide rail on the conveyor belt 17 When the linear motor 21 is clamped, the linear motor 21 drives the support arm 22 fixed to its output end to move, and the support arm 22 drives the scale column 23 to move accordingly. When the scale column 23 moves to the specified position, the roller 26 fixed to the bottom of the detection box 25 contacts the guide rail groove on the guide rail. Under the action of the second spring 24, the detection box 25 can move up and down. When the roller 26 rolls in the guide rail groove on the guide rail, the detection of the guide rail can be completed by observing the up and down position changes of the detection box 25. By observing the position changes of the detection box 25 and the scale column 23 when the roller 26 rolls in the guide rail groove, the guide rail can be detected more conveniently and quickly.

[0028] like Figures 3 to 6 As shown, a pair of exhaust pipes 3 are fixedly connected to the outer wall of the detection box 25; an exhaust box 31 is fixedly connected to the bottom of the exhaust pipe 3; the exhaust pipe 3 and the exhaust box 31 are in a communicating relationship. When the guide rail is transported by the conveyor belt 17, debris, dust and other impurities will remain on the surface. When the roller 26 rolls in the guide rail groove, an exhaust device is connected to the exhaust pipe 3. When the roller 26 rolls, the impurities in the guide rail groove are adsorbed and collected by the exhaust box 31, thereby reducing the contamination of the guide rail caused by impurities remaining in the guide rail groove.

[0029] like Figures 4 to 6 As shown, a plurality of brushes 4 are fixedly connected to the bottom of the detection box 25; the brushes 4 are located between the detection box 25 and the roller 26. When the roller 26 rolls in the guide rail groove, the vacuum box 31 absorbs the impurities in the guide rail groove, and a small amount of fine impurities that are not absorbed will be crushed by the roller 26 and attached to the surface of the roller 26. At this time, the surface of the roller 26 is cleaned by the brush 4, thereby reducing the deviation of the guide rail detection accuracy caused by impurities adhering to the surface of the roller 26.

[0030] like Figure 5 As shown, a fixing plate 5 is fixed to the top of the adjacent limit block 11; an air inlet pipe 51 is connected to the fixing plate 5; a plurality of air outlet holes 52 are opened in the middle of the fixing plate 5; when the guide rail reaches the top of the operating table 1 through the conveyor belt 17, its surface temperature will be greatly different from the room temperature due to processing reasons. When the guide rail is inspected, normal temperature gas is injected into the air inlet pipe 51, and the gas is blown toward the guide rail through the air outlet holes 52 through the inside of the fixing plate 5. By injecting normal temperature gas into the air inlet pipe 51 and blowing it to the guide rail through the air outlet holes 52, the temperature change of the guide rail itself during inspection, which causes the thermal expansion and contraction of the metal, thereby causing the inspection result to be inaccurate.

[0031] like Figure 5 As shown, a cleaning block 6 is slidably connected to the fixed plate 5; the cleaning block 6 is a set of corresponding settings. When the air outlet 52 continues to work for a period of time, the sliding cleaning block 6 can clean the dust attached to the surface of the air outlet 52, reducing the situation where the air outlet 52 is blocked due to dust accumulation.

[0032] Working principle: First pull the pull rod 16, and the movement of the pull rod 16 drives the support rod 13 to move, and the support rod 13 drives the rubber block 15 to move. Under the action of the first spring 14, the rubber block 15 moves to the specified position, and the guide rail to be inspected is placed on the conveyor belt 17. Then release the pull rod 16, and under the action of the first spring 14, the rubber block 15 clamps the guide rail to be inspected. Finally, the guide rail can be inspected by the inspection component 18. A spring 14 is provided. A rubber block 15 is fixed to the inner wall of the support rod 13. The guide rail to be tested is clamped. When the guide rail is placed on the conveyor belt 17 and clamped, the linear motor 21 is started. The linear motor 21 drives the support arm 22 fixed to its output end to move. The support arm 22 drives the scale column 23 to move accordingly. When the scale column 23 moves to the specified position, the roller 26 fixed to the bottom of the detection box 25 contacts the guide rail groove on the guide rail. Under the action of the second spring 24, the detection box 25 can move up and down. When the roller 26 rolls in the guide rail groove on the guide rail, the inspection of the guide rail can be completed by observing the changes in the upper and lower positions of the detection box 25. When the roller 26 rolls in the guide rail groove, the air extraction device is connected to the air extraction pipe 3. When the roller 26 rolls, the impurities in the guide rail groove are adsorbed and collected by the air extraction box 31. When the roller 26 rolls in the guide rail groove, the air extraction box 31 adsorbs the impurities in the guide rail groove. A small amount of fine impurities that are not adsorbed will be crushed by the roller 26 and attached to the surface of the roller 26. At this time, the brush 4 The surface of the roller 26 is cleaned, and when the guide rail is inspected, room temperature gas is injected into the air inlet pipe 51. The gas passes through the inside of the fixed plate 5 and is blown toward the guide rail through the air outlet 52. By injecting room temperature gas into the air inlet pipe 51 and blowing it through the air outlet 52 to the guide rail, the temperature change of the guide rail itself during inspection, which causes the thermal expansion and contraction of the metal, is reduced. After the air outlet 52 has been working for a period of time, the dust attached to the surface of the air outlet 52 can be cleaned by sliding the cleaning block 6, thereby reducing the blockage of the air outlet 52 due to dust accumulation.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
