Abstract
Description
Technical Field
[0001] This utility model relates to the field of drilling machine fixture technology, and in particular to a drilling and positioning fixture for a gas chamber support flange. Background Technology
[0002] The air chamber support flange is connected to other components, such as the brake base plate, axle housing, and machine housing, via bolt holes, securing the air chamber support in its corresponding position and ensuring that the air chamber does not shift or shake during operation. Multiple bolt holes are evenly distributed on the flange, and the drilling process is crucial in the machining of the air chamber support flange. Currently, CNC drilling machines are typically used to drill the flange, thus requiring positioning fixtures. However, existing positioning fixtures have poor versatility and are only applicable to air chamber support flanges of specific sizes. Therefore, a positioning fixture needs to be designed to address this lack of versatility.
[0003] Based on this, the present invention designs a drilling and positioning fixture for a gas chamber support flange to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a drilling and positioning tool for a gas chamber support flange, thereby solving the problems in the prior art.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: The fixture for drilling and positioning the gas chamber support flange includes a CNC drilling machine, a worktable for placing the gas chamber support flange on the CNC drilling machine, a base slidably mounted on the worktable, several positioning screws vertically fixed on the base, fine adjusting nuts threaded onto the positioning screws, a U-shaped pressure block below the fine adjusting nuts, and a sleeve horizontally fixed on the base. The sleeve surrounds the gas chamber support flange, and a threaded hole is opened in the sleeve. The threaded hole is threadedly connected to a horizontal adjusting screw, one end of which abuts against the outer wall of the gas chamber support flange.
[0006] Furthermore, a groove is opened on the upper surface of the worktable, and a slider is fixed on the lower surface of the base, with the groove and the slider being slidably connected.
[0007] Furthermore, the base is fixed to the worktable by a limiting block, which abuts against the outer wall of the base. The limiting block is fixed to the worktable by a positioning bolt and a positioning nut.
[0008] Furthermore, a through hole is provided on the limiting block, and the limiting block is rotatably connected to the positioning bolt through the through hole.
[0009] Furthermore, the fine adjusting nut is a butterfly nut.
[0010] Furthermore, a limiting groove is formed on the U-shaped pressure block along its length, with one end of the limiting groove extending to the end face of the U-shaped pressure block. The length of the U-shaped pressure block is greater than the diameter of the central circular through hole of the gas chamber support flange.
[0011] Furthermore, a plug gasket is installed at one end of the horizontal adjusting screw that contacts the outer wall of the gas chamber support flange, and a T-shaped handle is fixed at the other end.
[0012] Furthermore, the number of horizontal adjusting screws is at least two.
[0013] This utility model has the following beneficial effects: The positioning fixture of this invention has good versatility, is applicable to various types of gas chamber support flanges, and is easy to install and has high production efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It should be understood that the terms "upper", "middle", "outer", "inner", "lower" etc., which indicate orientation or positional relationship, are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, and therefore should not be construed as a limitation of the present utility model.
[0018] The attached figures illustrate specific embodiments of this utility model, such as... Figures 1-2As shown, this utility model is a drilling and positioning fixture for a gas chamber support flange, including a CNC drilling machine. A worktable 1 for placing the gas chamber support flange 7 is installed on the CNC drilling machine. A sliding groove 10 is formed on the upper surface of the worktable 1, and a slider 11 is fixed on the lower surface of the base 2. The sliding groove 10 and the slider 11 are slidably connected, allowing the base 2 to be slidably mounted on the worktable 1. The base 2 is fixed to the worktable 1 by a limiting block 12. A through hole is formed on the limiting block 12, allowing the limiting block 12 to rotate around the positioning bolt 13 in any direction. When rotated to a suitable angle, the limiting block 12 can abut against the outer wall of the base 2. At this time, the limiting block 12 is fixed to the worktable 1 by the positioning bolt 13 and the positioning nut 14.
[0019] Several positioning screws 3 are vertically fixed on the base 2. Fine adjusting nuts 4 are threaded onto the positioning screws 3. In use, the gas chamber support flange 7 is placed on the base 2, with the through hole on the gas chamber support flange 7 passing through the positioning screws 3. A U-shaped pressure block 5 is located below the fine adjusting nut 4, placed on the upper surface of the gas chamber support flange 7. A limiting groove 15 is formed along the length of the U-shaped pressure block 5, with one end extending to the end face of the U-shaped pressure block 5. The U-shaped pressure block 5 is horizontally inserted into the positioning screws 3 through the limiting groove 15. The length of the U-shaped pressure block 5 must be greater than the diameter of the central circular through hole of the gas chamber support flange 7 to ensure tight clamping of the gas chamber support flange 7 and prevent shaking during drilling. Rotating the fine adjusting nut 4 allows adjustment of the height of the U-shaped pressure block 5 according to the different thicknesses of the gas chamber support flange 7, enabling clamping and loosening of the gas chamber support flange 7. The fine adjusting nut 4 is a butterfly nut, easy to operate manually without tools. Since the U-shaped pressure block 5 has a limiting groove 15, the U-shaped pressure block 5 can be pulled away from the positioning screw 3 by slightly loosening the fine adjusting nut 4, which makes it easy to remove the air chamber bracket flange 7 and saves the time of adjusting the bolts.
[0020] Several sleeves 6 are horizontally fixed on the base 2, surrounding the gas chamber support flange 7. At least two sleeves 6 are arranged opposite each other. Threaded holes 8 are formed inside each sleeve 6, and these holes are threadedly connected to horizontal adjusting screws 9. There are also at least two horizontal adjusting screws 9. A rubber plug gasket 16 is installed at one end of the horizontal adjusting screw 9 that contacts the outer wall of the gas chamber support flange 7, abutting against the outer wall. The plug gasket 16 increases the contact area between the horizontal adjusting screw 9 and the gas chamber support flange 7, protects its surface from scratches, and increases friction. A T-shaped handle 17 is fixed at the other end. Rotating the T-shaped handle moves the horizontal adjusting screw 9 horizontally, thereby fixing the position of the gas chamber support flange 7 horizontally, accommodating gas chamber support flanges 7 of different sizes.
[0021] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to specific implementation methods.
