Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as Figures 1 to 4 As shown, a general-purpose inner hole grinding tool, including: worktable 1, scale screw 2, scale 3, support block fastening screw 4, support block 5, hole unit 6, hole unit fixing screw 7, T-shaped Fixed block 8, workpiece 9, platen bridge 10, screw 11;

[0020] The workbench 1 has twelve T-shaped slots, which can be adapted to three, four, six, and twelve uniformly distributed installation holes, and has a wide range of applications; the support block 5 is fastened by the support block screws 4 and the T-shaped fixed block 8 are connected, the T-shaped fixed block 8 moves in the T-shaped slot, so as to realize the adjustment of the position and size of the mounting hole, and the indexing line on the supporting block 5 can effectively indicate the radial position of the hole unit 6;

[0021] The hole unit 6 is...

Abstract

The invention discloses a general-purpose inner hole grinding tool with adjustable inner diameter, which comprises a workbench (1), a scale screw (2), a scale (3), a support block fastening screw (4), a support block ( 5), hole unit (6), hole unit fixing screw (7), T-shaped fixing block (8), workpiece (9), pressure plate bridge (10), screw (11); the workbench is connected with the main shaft For clamping other tooling parts; the scale is installed on the workbench of the machine tool through scale screws to display the radial position of the support block; the support block is installed in the T-shaped slot of the workbench through the support block screws , moving along the T-shaped slot can adapt to the inner hole size of the part, and then grind parts with different inner hole sizes; the invention extracts the hole as a unit, avoiding the waste caused by the transitional drilling of the previous tooling. The invention has the advantages of simple structure, good rigidity, convenient operation and wide application range.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a universal inner hole grinding tool with adjustable inner diameter. Background technique [0002] In the inner hole grinding process of bearing ring parts, due to the difference in part size, number of mounting holes, and hole diameter, often a part needs to be specially made with a faceplate tooling for clamping. This kind of tooling is generally steel parts, and the cost is high. , the waste is more obvious when the part is larger. In addition, another form of failure of faceplate tooling is transitional punching. In order to adapt to the new part size, it is often necessary to add holes to the tooling or remanufacture the tooling, so the reuse rate of traditional tooling is too low. [0003] The present invention proposes a universal inner hole grinding tool with wide applicability. The tool can change the position size, size and number of the mo...
