Description

Technical Field

[0001] This utility model relates to a fixture for producing split shaft housings, and more particularly to a milling and chamfering fixture for split shaft housings. Background Technology

[0002] Split-type shaft housings are widely used and important components in many fields such as automobiles and construction machinery. They typically consist of two halves, which are combined during assembly to form a complete shaft housing structure. This structure supports and protects transmission components and transmits torque. Milling is a critical process in the manufacturing of split-type shaft housings. Previously, milling of each half was often done separately. However, when milling individual halves, it's difficult to ensure consistent contact surfaces after milling. This can easily lead to gaps and misalignments during subsequent assembly, affecting the housing's sealing performance.

[0003] Based on this, this utility model designs a brake flange milling and drilling fixture to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a split-type shaft housing milling and chamfering fixture, which can quickly fix the split-type shaft housing on the machine tool worktable, is applicable to different models of split-type shaft housing, and solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] The split-type shaft housing milling and chamfering fixture includes a worktable with a fixed plate. Support blocks are symmetrically installed on the fixed plate, and the split-type shaft housing is placed between the two support blocks. A fixing nut is installed in the center of the fixed plate, and a fixing bolt is vertically threaded onto the fixing nut. A limit nut is installed on the fixing bolt, and a lower pressure block is provided between the limit nut and the fixing nut. An irregular through hole is opened in the center of the lower pressure block, and the fixing bolt passes through the irregular through hole. A support column is horizontally installed on the lower surface of the lower pressure block. Support blocks are installed on the left and right sides of the fixing bolt respectively.

[0007] The irregular through hole includes a first through hole and a second through hole. The diameter of the first through hole is smaller than that of the second through hole. The diameter of the first through hole is larger than that of the fixing bolt. The diameter of the second through hole is larger than the maximum outer diameter of the limit nut.

[0008] The height of the support block is greater than the outer radius of the mounting hole of the split-type shaft housing bearing.

[0009] The edge of the fixed plate is equipped with a positioning block. One end of the positioning block presses against the fixed plate, and the other end is fixed to the worktable by positioning bolts and positioning nuts.

[0010] The support column is fixed along the length of the lower pressure block on the two long sides of the lower pressure block. When in use, the axis of the support column is in the same direction as the axis of the split shaft housing.

[0011] This utility model has the following beneficial effects:

[0012] This invention can simultaneously position a set of balance shaft housing half-shells, synchronously complete the milling and chamfering of the two half-shells, ensure consistent contact surfaces, and improve processing efficiency. Furthermore, quick-release holes are provided on the lower pressure block, allowing for rapid replacement of the same model of balance shaft housing without frequent nut removal. In addition, the fixing plate of this invention is suitable for various machine tool worktables, offering strong versatility. Attached Figure Description

[0019] 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.

[0020] The attached figures illustrate specific embodiments of this utility model, such as... Figures 1-3As shown, the split-type shaft housing milling and chamfering fixture includes a worktable 1, a fixed plate 2 on the worktable 1, and a positioning block 3 at the edge of the fixed plate 2. One end of the positioning block 3 presses against the fixed plate 2, and the other end is fixed to the worktable 1 by a positioning bolt 4 and a positioning nut 5, so that the positioning block 3 presses tightly against the fixed plate 2 to prevent the fixed plate 2 from shifting. Support blocks 8 are symmetrically installed on the fixed plate 2, and support blocks 8 are installed on the left and right sides of the fixing bolt 10 respectively. The space between the two support blocks 8 is used to place the split-type shaft housing 6. The height of the support blocks 8 is greater than the outer radius of the bearing mounting hole of the split-type shaft housing 6. A fixing nut 9 is installed in the center of the fixing plate 2. A fixing bolt 10 is vertically threaded onto the fixing nut 9. A limiting nut 11 is installed on the fixing bolt 10. A lower pressure block 7 is provided between the limiting nut 11 and the fixing nut 9. An irregularly shaped through hole is opened in the center of the lower pressure block 7. The fixing bolt 10 passes through the irregularly shaped through hole. The irregularly shaped through hole includes a first through hole 72 and a second through hole 71. The two through holes are interconnected. The diameter of the first through hole 72 is smaller than that of the second through hole 71. The diameter of the first through hole 72 is larger than that of the fixing bolt 10. The diameter of the second through hole 71 is larger than the maximum outer diameter of the limiting nut 11. The narrowest part of the irregularly shaped through hole can accommodate the fixing bolt 10. Since the bearing mounting hole wall of the split shaft housing 6 is a semi-circular surface, a support column 73 is horizontally installed on the lower surface of the lower pressure block 7. The support column 73 is fixed along the length of the lower pressure block 7 on the two long sides of the lower pressure block 7. In use, the axis of the support column 73 is in the same direction as the axis of the split shaft housing 6, which can act as a fulcrum.

[0021] For first-time use, place the two halves of the 6-piece split housing facing upwards, and follow the instructions. Figure 2 The lower pressure block 7 is placed on the support block 6. The fixing bolt 10 passes through the irregular through hole on the lower pressure block 7 and is locked in the first through hole 71. Tighten the limiting nut 11 so that the two support columns 73 at the bottom of the lower pressure block 7 are respectively attached to the inner wall of the split shaft housing 6. After processing, when disassembling, simply loosen the nut 11 slightly, push the lower pressure block 7 towards the second through hole 71 so that the fixing bolt 10 is directly above the second through hole 71, take the lower pressure block 7 upward, let the limiting nut 11 pass through the second through hole 71, remove the split shaft housing 6 that has been milled and chamfered, put in the new split shaft housing 6, and then reinstall the lower pressure block 7 in the same way.
