Abstract
The utility model relates to a bowing toothed plate fixing device which comprises a fixing support, a key, a teeth-roller shaft, a bowing toothed plate and a T-type bolt. The fixing support is a disc -shape support, wherein an inner bore is arranged inside the fixing support and the outer portion of the fixing support extends to six pentagon-structures. The fixing support is connected with the teeth-roller shaft through the key, a key groove parallel to the shaft direction of the teeth-roller shaft is installed on the inner wall of the fixing support, one portion of the key is placed inside the key groove, the other portion of the key is placed inside a recessed groove on the teeth-roller shaft, the bowing toothed plate is provided with a T-type groove, the bowing toothed-plate is connected with a screw thread of the fixing support through the T-type bolt, and the bolt head end of the T-type bolt is pressed on the pentagon-structure of the fixing support. Based on an existing fixing support, the bowing toothed plate fixing device is added with the T-type bolt and the fixing bowing toothed plate, and thereby an occurrence that the toothed plate bolts loosen and fall off can be reduced.
Description
Technical field
The utility model relates to a kind of bow tooth board fixer, belongs to mechanical field.
Background technology
The mode of the most employing of existing disintegrating machine tapping on fixed mount is the bow tooth plate fixedly, and this mode will be once stripped thread will cause the bow tooth plate to fix.
The utility model content
Technical problem to be solved in the utility model provides a kind of bow tooth board fixer, has improved the fixedly mode of bow tooth plate, when T-shaped bolt failure, can pull down the bow tooth plate and change T-shaped bolt, and convenient for maintaining is changed.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of bow tooth board fixer, comprise fixed mount, key, the discaling roll axle, the bow tooth plate, T-shaped bolt, wherein, described fixed mount extends the disk-shaped support of 6 pentagonal configuration for inner with endoporus and outside, described fixed mount is connected on the discaling roll axle by key, the inwall of described fixed mount is provided with the keyway with discaling roll axle axially parallel, a described key part places keyway, another part places in the groove on the discaling roll axle, described bow tooth plate is provided with T-shaped groove, described bow tooth plate is threaded with fixed mount by T-shaped bolt, and the bolt head side pressure of described T-shaped bolt is on the fixed mount pentagonal configuration.
The beneficial effects of the utility model are: increased the T-shaped bolt of T-shaped groove on existing fixed mount basis, fixing bow tooth plate, reducing the tooth plate bolt looseness comes off, having avoided the tooth plate that female silk stripped thread causes on the fixed mount to become flexible with the offside discaling roll bumps, reduced maintenance cost, increase service life, avoided the fixing drawback of bow tooth plate after screw stripped thread or the fracture.
Description of drawings
Fig. 1 is the structural representation of the utility model bow tooth board fixer;
In the accompanying drawing, the list of parts of each label representative is as follows:
1, bow tooth plate, 2, fixed mount, 3, the discaling roll axle, 4, T-shaped bolt, 5, key.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
As shown in Figure 1, a kind of bow tooth board fixer, comprise fixed mount 2, key 5, discaling roll axle 3, bow tooth plate 1, T-shaped bolt 4, wherein, described fixed mount 2 extends the disk-shaped support of 6 pentagonal configuration for inner with endoporus and outside, described fixed mount 2 is connected on the discaling roll axle 3 by key 5, the inwall of described fixed mount 2 is provided with the keyway with discaling roll axle 3 axially parallels, described key 5 parts place keyway, another part places in the groove on the discaling roll axle 3, described bow tooth plate 1 is provided with T-shaped groove, and described bow tooth plate 1 is threaded with fixed mount 2 by T-shaped bolt 4, and the bolt head side pressure of described T-shaped bolt 4 is on fixed mount 2 pentagonal configuration.
During the normal operation of the utility model bow tooth board fixer, discaling roll axle 3 drives fixed mount 2 and 1 rotations of bow tooth plate.When T-shaped bolt 4 damages, stop, bow tooth plate 1 is pulled down, change T-shaped bolt 4, get final product.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
