Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing and detection, in particular to a universal airtightness detection device for gears. Background Art

[0002] During the gear finishing process, both sides of the passive gear need to be finish-turned once. In order to reduce the processing mismatch caused by shim iron chips, an error-proofing device is often required. Generally, an airtight block is used to support the passive gear, and a reasonable airtight amount is set to detect whether the gear and the airtight block fit together. Due to the different sizes of gears, when different gears need to be finished, airtight blocks of different sizes need to be designed, and the corresponding airtight blocks also need to be replaced when the mold is changed. Due to the large number of airtight hole sections, an airtight block needs to be placed in each hole section. Each time the mold is changed, the corresponding airtight block needs to be found and replaced, which takes a long time and has low work efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a universal gear airtightness detection device, which can solve the problem that in the existing gear finishing process, when machining gears of different sizes, corresponding airtight blocks need to be found and replaced, resulting in a long time and low work efficiency.

[0004] In order to solve the above problems, the technical solution adopted by the present invention is: this universal gear airtightness detection device includes a machine tool body, airtight devices are respectively arranged at the positions of the airtight holes of the machine tool body, a clamping mechanism is arranged between the airtight devices on the machine tool body, and the sealing cover on the airtight device has an airtight hole.

[0005] In the technical solution of the above-mentioned universal airtightness detection device for gears, a more specific technical solution can also be: the airtightness device includes a main body, the sealing cover and a fixed block, a row of airtightness holes for the airtightness device is provided on the main body along the length direction, the sealing cover is placed on the row of airtightness holes for the airtightness device, and the surface of the sealing cover in contact with the main body is in contact with the main body; fixing blocks for fixing the sealing cover are respectively provided at both ends of one side of the sealing cover on the main body.

[0006] In some possible embodiments, the end of the fixing block facing the sealing cover is a wedge-shaped end, which is crimped onto the sealing cover; the top surface of at least the side of the sealing cover that is crimped onto the fixing block is tilted downward, and its inclination angle is adapted to the inclination angle of the wedge-shaped end of the fixing block; the fixing block is fastened to the main body by fasteners.

[0007] In some possible implementation schemes, a gear inner diameter value is provided on the main body at the other side of the airtight hole of the airtight device corresponding to the airtight hole.

[0008] In some possible implementation schemes, the clamping mechanism includes an arc-shaped block and a snap-on block, and the surface of the arc-shaped block for clamping the gear is provided with concave and convex parts adapted to the gear.

[0009] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0010] 1. Since airtight devices are respectively provided at the positions of the multiple airtight holes of the machine tool body, and the sealing cover on the airtight device has an airtight hole, the position of the airtight hole on the sealing cover can be quickly adjusted to adapt to gears of different sizes. There is no need to find corresponding airtight blocks separately, which saves time and improves work efficiency.

[0011] 2. Since the sealing cover is directly placed on the position where the airtight hole of the airtight device is provided on the body and is crimped by the fixing block, and the fixing block is fixed to the body by the fastener, when it is necessary to adjust the sealing cover to move inward or outward, it is only necessary to loosen the fastener and the fixing piece to move the sealing cover and adjust the position of the air hole thereon to adapt to the inner diameter of the gear, which saves time.
