Abstract
The utility model relates to a flat hammer fastening device of an impact crusher, and the device comprises a bolt, a lock nut, a nut, a wedge block and a limiting block. The device is characterized in that the bolt is arranged below the wedge block, the limiting block is arranged at the middle part of the inclined plane of the wedge block, and the lock nut is arranged on the bolt. A flat hammer can be fastened on a flat hammer frame very firmly under the action of the wedge block, so that the device can be used for avoiding the looseness of the flat hammer, reducing the failure rate and reducing mechanical damages, and is also very convenient to mount and maintain.
Description
Technical field
The present invention relates to a kind of bar fastener of impact breaker, this device comprises: bolt, locking nut, nut, voussoir, confinement block.
Background technology
The bar of disintegrating machine is fastening to be crucial.If can not be effectively fastening, when bar rotates at a high speed and be broken material impacting, can produce the loosening of bar, even make the outbound phenomenon of bar, will cause the damage of disintegrating machine, cause stopping production.
Existing a kind of impact breaker bar fastener; Like practicality novel 200720068667.0; Have main shaft, axle sleeve and hammer dish to constitute rotor block, bar, compact heap, wherein, per two hammer dish side faces are provided with equal number also can be with the mounting groove of bar insertion; Compact heap is the voussoir form; The apparent surface of the mounting groove of each bar and two hammer dishes is the inclined plane, and its gradient is complementary with the inclined-plane of compact heap, compact heap be installed between the inclined plane of bottom surface and bar of mounting groove and two compact heaps through packing ring and bolt relatively the bar tension so that being fixed axially and radially of bar in the mounting groove of hammer dish; Extremely fitting in the inclined-plane that requires to be contacted, otherwise can cause a little or line contacts.During installation, very tight for what voussoir was pushed up, need the finishing binding face and repeatedly beat pulling block, and repeatedly tight a bolt, install cumbersome.All need seven parts, wherein pulling block is wanted casting, and is exposed in the bump and wash surface of broken material.
Summary of the invention
The purpose of the utility model is for overcoming the weak point of above-mentioned prior art, provide a kind of bolt that utilizes with the direct jack-up of voussoir, under the effect of voussoir gradient, fastening bar.Most critical be voussoir, bar fastener, can be with very firm being fixed on the hammer carrier of bar.
For realizing above-mentioned purpose, the utility model comprises: bolt, locking nut, nut, voussoir, confinement block, bolt have confinement block at the middle part on voussoir inclined-plane below voussoir, locking nut is arranged on the bolt; A whole set of fastener be arranged on voussoir under.Utilize screw bolt and nut with the direct jack-up of voussoir, utilize the effect compressing bar of voussoir gradient.Simultaneously, for not making the voussoir skew, confinement block is arranged at the middle part on voussoir inclined-plane.When bolt is screwed to when very fastening, the locking nut of screwing becomes flexible when rotation is with broken material at a high speed to prevent bar.A whole set of fastener be arranged on voussoir under, can effectively prevent the bump of broken material and wash away.
The advantage of the utility model
The utility model has overcome prior art trouble has been installed, and pulling block is exposed to the bump of broken material and the deficiency in the wash surface.Its advantage is that mechanical structure is reasonable, and the direction of power and application point are on same direction, and package unit has enough rigidity, and is simple in structure, be convenient to make and the convenient for maintaining complete machine.
Description of drawings
Accompanying drawing is the utility model structural representation and force analysis figure.Fig. 1 is the utility model structural representation; Fig. 2 is an A-A profile among Fig. 1; Fig. 3 is force analysis figure.Among Fig. 1: 1, bolt, 2, locking nut 3, nut, 4, voussoir, 5, confinement block;
The specific embodiment
As shown in the figure: as to utilize bolt to pass through nut, at the effect lower compression bar of voussoir gradient with the direct jack-up of voussoir.For not making the voussoir skew, increase confinement block at the middle part on voussoir inclined-plane.When bolt is screwed to when very fastening, the locking nut of screwing plays the effect that prevents that bar from becoming flexible when rotation is with broken material at a high speed.
Claims (2)
1. the bar fastener of an impact breaker, this device comprises: bolt, locking nut, nut, voussoir, confinement block is characterized in that: bolt has confinement block at the middle part on voussoir inclined-plane below voussoir, locking nut is arranged on the bolt.
2. the bar fastener of a kind of impact breaker according to claim 1 is characterized in that: a whole set of fastener be arranged on voussoir under.
