Description
Technical field
The utility model belongs to mining machinery and manufactures and designs the field, especially belongs to impact breaker and manufactures and designs the field, particularly the syndeton of disintegrating machine liner plate and casing.
Background technology
It is broken that the liner plate of impact breaker plays a part that in shattering process building stones are carried out repetition, so the wearing and tearing of liner plate are comparatively serious, belong to the consumable accessory that needs are often changed.In the impact breaker field, liner plate is generally bolt fastening structure with being connected of casing.
In actual use; Come fastening liner plate to have such problem with bolt fastening structure: because liner plate repeats constantly to receive the percussion from building stones with being connected of casing; The bolt of fastening liner plate and casing can be out of shape; Bring very big difficulty for the replacing liner plate, and when changing liner plate, also need use new bolt to come fastening liner plate and casing.If the distortion of bolt too seriously can cause liner plate to come off, liner plate comes off and can damage frame for movement in the disintegrating machine in machine running process, badly influences the stability of complete machine operation.
Summary of the invention
The utility model discloses the syndeton of a kind of disintegrating machine liner plate and casing according to the deficiency of prior art.The problem that the utility model will solve provides the syndeton that a kind of easy to connect, fixing-stable, installing/dismounting are easy to disintegrating machine liner plate and casing, and the utility model also provides a kind of cap that draws.
The utility model is realized through following technical scheme.
The syndeton of disintegrating machine liner plate and casing; Be connected fixedly liner plate and boxboard with connecting bolt by drawing cap to pass through foundary weight, wherein: the said cap that draws is the hollow-cone body, and through hole is arranged at the top; The middle part has opening to be communicated with conical internal cavity, and the bottom has with the bellmouth of liner plate matees the fixedly bullet bottom of liner plate.
Further said connecting bolt draws the square-head nut of cap conical internal cavity to form by passing the screw rod that draws crown portion through hole with being positioned at, and foundary weight passes through opening and draws the cap conical internal cavity between square-head nut and boxboard.Foundary weight is L-shaped.
Draw cap to adopt the casting of high-abrasive material special steel to form; Overall structure is tapered; The bullet bottom cooperates with the bellmouth of liner plate, because the face that draws cap to cooperate with liner plate is bigger, draws cap still can ensure with liner plate have enough areas that cooperates to reach the effect of fastening liner plate and casing under the impact wear of building stones receiving; Foundary weight and square-head nut place and draw cap inner; Pass and draw the screw rod of crown portion through hole to cooperate with square-head nut, just can easily the dismounting liner plate through pine or fastening screw, and such syndeton is in that receive still can good fastening liner plate and casing under the percussion of building stones.
During use,, will draw the cap upper end to pass the hole of accomplishing fluently in advance on the casing then, penetrate foundary weight, and tighten up and pass the screw rod that draws crown portion through hole to cooperate with square-head nut through drawing the cap intermediate openings with drawing cap bullet bottom to cooperate with the bellmouth of liner plate; The cap conical internal cavity is limited can not to rotate drawing for screw rod long enough, square-head nut, and the screw rod after tightening up pushes against foundary weight fixes fastening realization liner plate of the bellmouth that draws cap bullet bottom and liner plate and boxboard.During dismounting and change, only need unclamp screw rod, pull out foundary weight, draw cap and liner plate to take off, convenient and swift.
The utility model draws the cap jockey simple in structure, draws cap and liner plate to adopt taper fit, has increased the secure fit area; Improved safety coefficient greatly; The easy disassembly liner plate makes the such consumable accessory of replacing liner plate convenient and swift, has reduced working strength of workers; Reduce the time of changing consumable accessory, improved the business efficiency of machine.

The specific embodiment
Through the specific embodiment and accompanying drawing the utility model is further specified below.Embodiment is used to explain the utility model, limits the utility model never in any form.
In conjunction with Fig. 1 to Fig. 7.
The syndeton of disintegrating machine liner plate and casing; By drawing cap 1 to be connected fixedly liner plate 4 and boxboard 5 with connecting bolt through foundary weight 2; Drawing cap 1 is the hollow-cone body; Through hole 1a is arranged at the top, and the middle part has opening 1c to be communicated with conical internal cavity, and the bottom has and the fixing bullet bottom 1b of liner plate 4 of the bellmouth 4a of liner plate 4 coupling.Connecting bolt draws the square-head nut 3 of cap 1 conical internal cavity to form by passing the screw rod 6 that draws cap 1 top through hole 1a with being positioned at, and foundary weight 2 passes through opening 1c and draws cap 1 conical internal cavity between square-head nut 3 and boxboard 5.Foundary weight 2 is L-shaped.
As shown in Figure 2, Fig. 2 is that the utility model draws a kind of structural representation of cap, and shown to draw cap 1 bullet bottom 1b to have outstanding stupefied, and the bellmouth 4a coupling of the outstanding stupefied and liner plate 4 of bullet bottom 1b is fixing during use.
As shown in Figure 3, Fig. 3 is that the utility model draws the another kind of structural representation of cap; Shown to draw cap 1 bullet bottom 1b be that tubaeform progressive change is big, and limit that 1b tubaeform progressive change in bullet bottom is big during use and the bellmouth 4a of liner plate 4 coupling are fixing.
Installation and application; With drawing cap 1 bullet bottom 1a to cooperate with the bellmouth 4a of liner plate 4; To draw cap 1 upper end to pass the hole of accomplishing fluently in advance on the casing 5 then, penetrate foundary weight 2, and tighten up and pass the screw rod 6 that draws cap 1 top through hole 1a to cooperate with square-head nut 3 through drawing cap intermediate openings 1c; Cap 1 conical internal cavity is limited can not to rotate drawing for screw rod 6 long enoughs, square-head nut 3, and the screw rod 6 after tightening up pushes against foundary weight 2 makes the fastening realization liner plate 4 of the bellmouth 4a that draws cap 1 bullet bottom 1a and liner plate 4 fixing with boxboard 5.During dismounting and change, only need unclamp screw rod 6, pull out foundary weight 2, draw cap 1 and liner plate 4 to take off, convenient and swift.
