Abstract
Description
Technical Field
[0001] The present application relates to the technical field of bridge housing inspection tooling, and in particular to a novel three-coordinate inspection and positioning tooling. Background Art
[0002] Currently, coordinate measuring machines are widely used in various factories as a common measuring equipment. However, when inspecting products, due to the specific appearance of various products, a corresponding inspection work needs to be designed for each product.
[0003] The purpose of the utility model is to provide a universal inspection tool for inspecting bridge housings with shaft heads. According to different bridge housing lengths, a V-shaped block movable by a scale on a bottom plate can be quickly adjusted to a required position. By limiting the freedom of the V-shaped iron and supplemented by a wide-seat right-angle ruler with a thimble, the purpose of multiple rapid clamping, alignment and detection can be achieved.
[0004] For the inspection of axle housings with shaft heads, a wide-seated angle ruler is usually used to align the V-shaped iron on a marble workbench, then the axle housing is hoisted to the V-shaped iron for positioning, a level is used to level the axle housing, and finally the position of the axle housing on the workbench is determined by marking. This traditional solution requires alignment every time the V-shaped iron is loaded, as the position is not fixed, and because the alignment level of each inspector is inconsistent, the inspection error increases.
[0005] The existing technology usually uses a wide-seated square to align the V-shaped iron on the marble workbench, then hoists the axle shell to the V-shaped iron for positioning, uses a level to level the axle shell, and finally determines the position of the axle shell on the workbench by marking. This technology has the following disadvantages:
[0006] (1) The position of the V-shaped iron is not fixed, and the V-shaped iron needs to be aligned every time a part is loaded, which reduces the inspection efficiency and affects the consistency;
[0007] (2) The alignment level of each inspector is inconsistent, which can easily lead to inspection errors and poor inspection consistency;
[0008] (3) Adjusting the tooling on a marble workbench can easily cause wear on the workbench and affect the accuracy of the inspection. Utility Model Content
[0009] In order to solve the existing bridge housing positioning inspection problem and improve the inspection quality and efficiency, the present application provides a new three-coordinate inspection and positioning tooling.
[0010] A novel three-coordinate inspection and positioning tooling provided in the present application adopts the following technical solution.
[0011] A new type of three-coordinate inspection and positioning tooling, including:
[0012] A bottom plate, which is a fixed base of the tooling, and a scale ruler is arranged on the bottom plate along the side-by-side direction of the positioning assembly;
[0013] A positioning assembly, wherein a plurality of positioning assemblies are arranged side by side and spaced apart on the bottom plate, wherein the positioning assembly comprises a positioning assembly seat and a positioning block, and the positioning assembly seat is slidably connected to the bottom plate through a slider rail;
[0014] An ejector assembly, the ejector assembly comprising an ejector seat and an ejector, the ejector seat being arranged on a bottom plate and located between a plurality of positioning assemblies, the ejector being located on the top of the ejector seat and being threadedly connected to the ejector seat;
[0015] The locking assembly is used to lock the sliding position of the positioning assembly on the base plate.
[0016] By adopting the above technical solution, through the setting of the bottom plate as the fixed base of the tooling, the inspection operations are all performed on the bottom plate instead of on the marble workbench, so the wear of the marble workbench can be reduced. After the bottom plate is worn, the replacement of the bottom plate is more convenient than replacing the marble workbench, with low cost and little impact on the inspection accuracy. Through the setting of several positioning assemblies, the workpiece can be placed on several positioning assemblies for positioning, and the positioning assembly can slide on the bottom plate to adjust the spacing, which can be suitable for different bridge housing workpieces. At the same time, a scale ruler is set on the bottom plate, which can facilitate the operator to accurately adjust the spacing. Through the setting of the ejector pin, auxiliary support of the workpiece during the positioning process is achieved. Through the setting of the locking assembly, the positioning of the positioning assembly at any position on the slide rail is achieved, improving the positioning stability and accuracy.
[0017] Optionally, a V-shaped groove structure is provided on the top of the positioning block.
[0018] By adopting the above technical solution, the design of the V-groove structure is simple in structure, the placement of the bridge shell is more stable, and the requirements for positioning and use of the bridge shell can be met.
[0019] Optionally, a pad is provided in the V-shaped groove.
[0020] By adopting the above technical solution, the positioning in the height direction of the bridge housing is achieved, the wear of the positioning block body is reduced, and the maintenance cost is reduced.
[0021] Optionally, a rail protection cover is provided on the slide rail.
[0022] By adopting the above technical solution, a track protection cover is arranged on the slide rail to play a dust protection role.
[0023] Optionally, the ejector assembly further comprises a tightening rod, which penetrates into the ejector seat from one side of the ejector seat to abut against the ejector and cooperates with the thread of the ejector seat.
[0024] By adopting the above technical solution and setting the tightening rod, after the ejector pin is screwed into the ejector pin seat to determine the ejector pin height, the tightening rod is tightened, and the end of the tightening rod is screwed into the ejector pin of the ejector pin seat to abut against each other for position fixing, thereby preventing the ejector pin from loosening.
[0025] Optionally, the positioning assembly seat is provided with a locking threaded hole, and the locking assembly includes a locking top shaft and a locking wrench. The locking top shaft is threadedly matched with the locking threaded hole, and the locking wrench is arranged at the top end of the locking top shaft.
[0026] By adopting the above technical solution, the locking top shaft can be rotated by rotating the locking wrench. The locking top shaft is threadedly matched with the locking threaded hole, so the locking top shaft will move up and down. When it moves downward until the lower end hits the bottom plate or the slide rail, friction will play a locking role, thereby positioning and locking the positioning assembly.
[0027] Optionally, a pointer is provided on the positioning assembly.
[0028] By adopting the above technical solution, the pointer can be set to compare with the scale ruler on the bottom plate, which is convenient for manual observation and more accurate adjustment of the positioning assembly.
[0029] In summary, this application at least includes the following beneficial effects:
[0030] 1. The position of the positioning block is relatively fixed. Each time a piece is loaded, it is necessary to slide and align the positioning block, which reduces the difficulty of manual inspection and no longer requires manual alignment, which is conducive to improving the consistency of inspection results;
[0031] 2. The sliding mode of the positioning block is simple, and a locking assembly is also provided to lock the positioning assembly, which reduces the manual inspection operation process and improves the inspection efficiency;
[0032] 3. By setting up the bottom plate as the fixed base of the tooling, inspection operations are all performed on the bottom plate instead of on the marble workbench, so the wear of the marble workbench can be reduced and the life of the equipment can be improved; after the bottom plate is worn, the replacement of the bottom plate is more convenient than replacing the marble workbench, with low cost and little impact on the inspection accuracy.
