Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, the technical features mentioned in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

As shown in the structural schematic diagram of the clutch and brake part of the bar shear in FIG. 1, the meshing teeth 111 on the bracket 11 are driven by a chain or a belt, so that the bracket 11 rotates around the main shaft 10 to open the brake at A, that is, as shown in FIG. 2, the air bag 8 is inflated by the air pipe 7, the friction block 9 is driven to move rightwards to leave the rotating disc 13, and the rotating disc 13 is fixed with the main shaft 10; closing the clutch at B, i.e. inflating the air bag 8 of the clutch part as shown in fig. 3, causes the friction block 9 to move to the right, abutting against the rotating disc 13 at that point, the rotating disc 13 is fixed with the main shaft 10, thus causing the main shaft 10 to rotate. As shown in fig. 1, the rotation of the main shaft 10 drives the transmission gear 12 to rotate. The drive gear 12 is further connected to a shear knife (not shown).

As shown in fig. 2, which is an enlarged view of a portion a of fig. 1, the stopper is mounted on the engaging plate 2, and the engaging plate 2 is mounted on the chassis 1. Fastening bolts 3 are inserted into the fastening discs 2, and the fastening bolts 3 are combined in threaded fixing holes 101 in the chassis 1. A plurality of gaskets 6 are arranged between the buckling disc 2 and the chassis 1, and the gaskets 6 are arranged on the fastening bolts 3 in a penetrating way. The pads 9 wear during use and therefore it is necessary to remove one pad 6 at regular intervals to ensure the performance of the brake. However, the whole buckling disc 2 needs to be dismantled when the gasket 6 is dismantled, and the gasket is easy to drop when the gasket 6 is taken out from the fastening bolt 3, which is very inconvenient. Like the clutch part shown in fig. 3, the friction pad 9 is worn after a certain period of use, and it is necessary to remove one pad 6.

As shown in the improvement of figure 4. Note that the figure is a simplified figure, and the structure is slightly different from that of fig. 1, but the principle is the same. The improvement mainly lies in that: (1) removing the gasket 6; (2) an adjusting bolt 4 is additionally arranged.

The spacer 6 between the chassis 1 and the snap disc 2 is removed. A plurality of thread adjusting holes 22 are formed in the buckling disc 2, the thread adjusting holes 22 are threaded holes, the thread adjusting holes 22 penetrate through the buckling disc 2 in the thickness direction, and adjusting bolts 4 are screwed into the thread adjusting holes 22. The inner end of the adjusting bolt 4 extends out of the buckling disc 2 and is tightly propped against the outer side surface of the chassis 1. In this way, the acting force directions of the fastening bolts 3 and the adjusting bolts 4 on the buckling disc 2 are opposite, and the chassis 1 and the buckling disc 2 have the tendency of being attached to each other due to the tensioning action of the fastening bolts 3; the distance between the chassis 1 and the snap disc 2 is limited not to be over-fitted due to the adjusting bolt 4. Thus, when the friction block 9 is worn, the adjusting bolt 4 is screwed outwards for a certain distance (the distance of movement can be judged by the angle of rotation of the adjusting bolt 4), and then the fastening bolt 3 is screwed.

The through holes 21 for installing the fastening bolts 3 in the chassis 1 are also smooth holes penetrating the engaging plate 2 in the thickness direction.

As shown in fig. 5, the engaging plate 2 is circular, and the through holes 21 and the screw adjusting holes 22 are distributed on the outer edge of the engaging plate 2. As can be seen from fig. 5, the fastening bolts 3 and the adjusting bolts 4 are distributed on the outer edge of the snap disc 2. And the fastening bolts 3 and the adjusting bolts 4 are arranged at intervals, i.e. the adjusting bolts 4 are arranged between adjacent fastening bolts 3. As shown in fig. 4, the positioning rings 5 are further disposed in the uppermost and lowermost through holes 21 (i.e., the positions indicated by C and D in fig. 5), the positioning rings 5 are in clearance fit with the fastening bolts 3, and the positioning rings 5 are used for strictly controlling the concentricity between the buckling disk 2 and the chassis 1 because the buckling disk 2 tends to drop. It is possible to provide the positioning rings 5 in all the through holes 21, but it is preferable to provide them only in the uppermost and lowermost through holes 21, because this is easier and provides a good positioning of the snap discs 2.

In summary, in this embodiment, the adjusting bolts 4 are used to replace the original plurality of gaskets 6, and the original manner of reducing the gaskets 6 is adjusted to control the distance between the chassis 1 and the buckling disc 2 by rotating the adjusting bolts 4, so as to achieve the purpose of facilitating adjustment. When the distance between the chassis 1 and the buckling disc 2 needs to be reduced, the adjusting bolt 4 is screwed to the right in the middle for a short distance, and the fastening bolt 3 is fastened.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
