Description

Technical Field

[0001] The utility model relates to a positioning tool, in particular to a machined positioning tool for air supply grille profiles. Background Art

[0002] The rail vehicle air supply grille profile is an important component in the subway car. In order to prevent debris from entering the car, improve the air quality in the car and increase the comfort level, some air vents are generally opened on the back of the air supply grille profile. Most of these air vents are of the same size, and the spacing between adjacent air vents is the same. They are evenly distributed according to the overall length of the rail vehicle, such as Figure 1 Air supply grille profile shown.

[0003] Therefore, for air supply grille profiles of different lengths, while ensuring that the air outlet sizes on the air supply grille profiles of different lengths are the same and the spacing between adjacent air outlets is the same, the sizes of the first and last air outlets on the air supply grille profiles of different lengths from the ends of the corresponding air supply grille profiles are also different. If one positioning tool is used, only air supply grille profiles of corresponding sizes can be processed, resulting in low utilization rate; if multiple positioning tools are used, the tools must be replaced frequently, reducing work efficiency.

[0004] Moreover, the distance between adjacent air outlets on each air supply grille profile is relatively close. During the machining of air outlets, in order to ensure that the depth of the air outlets is consistent and that the workpiece does not deform during processing, a pressure plate must be set between adjacent air outlets. If the pressure plate is not tightened in the right position, it is easy to collide with the tool and cause a processing accident. Utility Model Content

[0005] The technical problem to be solved by the utility model is that in the prior art, for air supply grille profiles of different sizes, it is inconvenient to position the air outlet during machining, and it is easy to collide with the cutter during the machining process of the air outlet, resulting in machining accidents.

[0006] In order to solve the above technical problems, a technical solution provided by the utility model is:

[0007] A machine-mounted positioning tool for an air supply grille profile comprises a tool body, the tool body comprises a tool base plate, a sliding positioning block and a pressure plate, the upper end surface of the tool base plate is provided with a placement groove and a sliding groove, the air supply grille profile is placed in the placement groove, the sliding positioning block is provided in the sliding groove, short protrusions are evenly distributed on the sliding positioning block, the distance between two adjacent short protrusions matches the length dimension of the air outlet on the air supply grille profile, one end of the pressure plate is arranged at a position between two air outlets on the air supply grille profile, and the other end extends out of the edge of the tool base plate after corresponding to the short protrusions on the sliding positioning block up and down, a support block is arranged below one end of the pressure plate extending out of the edge of the tool base plate, the support block is arranged on a machine tool, and a bolt is arranged on the pressure plate extending out of the edge of the tool base plate, and the other end of the bolt is fixed to the machine tool.

[0008] Furthermore, the inner bottom surface of the placement groove is an inclined surface, and the inclination angle matches the inclination angle of the lower end surface of the air supply grille profile to be processed. After the air supply grille profile is placed in the placement groove, the upper end surface of the air supply grille profile is horizontal.

[0009] Furthermore, a long protrusion is arranged in the middle position of the sliding groove, the short protrusion is arranged on the upper end surface of the sliding positioning block, and a long groove is arranged in the middle position of the lower end surface of the sliding positioning block. The size of the long groove matches the size of the long protrusion, the long protrusion can be arranged in the long groove, and the sliding positioning block can move freely in the sliding groove.

[0010] Furthermore, the pressing plate includes a pressing end and a fixed end, the pressing end and the fixed end are an integrated structure, the width of the pressing end is not greater than the distance between two adjacent air outlets on the air supply grille profile, the pressing end is arranged at a position between the two air outlets on the air supply grille profile, the fixed end extends out of the edge of the tooling base plate and is arranged on the support block, an adjustable fixing hole is arranged on the fixed end, and the bolt is arranged in the adjustable fixing hole between the support block and the tooling base plate.

[0011] Furthermore, the head end of the bolt is placed in the T-slot on the machine tool, and the tail end passes through the adjustable fixing hole from bottom to top and is fixed using a gasket and a nut.

[0012] The beneficial effects of the utility model are:

[0013] 1. The sliding positioning block in the utility model can move freely in the sliding groove, and the distance between two adjacent short protrusions on the sliding positioning block matches the length dimension of the air outlet on the air supply grille profile. For air supply grille profiles with different end dimensions, it is only necessary to make the first short protrusion on the left end of the sliding positioning block correspond to the position between the first and second air outlets to be processed from the left on the corresponding air supply grille profile. In this way, the position on the air supply grille profile corresponding to each two adjacent short protrusions on the sliding positioning block is the position where the air outlet needs to be opened, and there is no need to consider the size of the distance between the first and last air outlets on the air supply grille profile and the end of the corresponding air supply grille profile. It can be applicable to air supply grille profiles of different sizes, has high utilization rate, does not need to frequently replace positioning tooling, and improves work efficiency.

[0014] 2. In the utility model, every two air outlets on the air supply grille profile are separated by a pressure plate, so that when multiple air outlets are machined at the same time, it is not easy to collide with the cutter and a processing accident is not easy to occur; in addition, the pressure plate is fixed to the machine tool with bolts, which can firmly press the air supply grille profile that needs to be machined, ensuring that the depth of the air outlet is consistent during machining and no deformation occurs.
