Description
Technical field
The utility model relates to a kind of frame positioner, especially relates to a kind of frame positioner that is used for gyratory crusher, belongs to parts in the gyratory crusher.
Background technology
The frame positioner that is used for gyratory crusher now in the technology comprises frame, frame flange and alignment pin; Alignment pin is a cylindrical structural; On frame and frame flange, be respectively arranged with frame hole and frame flange hole; The alignment pin cross-under in frame hole and frame flange hole, thereby play positioning action to frame and frame flange.But; Because the alignment pin of the existing frame positioner that is used for gyratory crusher and frame hole and frame flange hole cooperatively interact; Generally all adopt interference fits or interference fit; The structural design of such frame positioner is reasonable inadequately, and performance is reliable inadequately, reduced gyratory crusher overall performance.This is because the condition of work and the environment of gyratory crusher are all relatively poor, and the vibration in the course of work is big and dust is big, and vibration makes being combined with of alignment pin and frame hole and frame flange hole loosening easily; Cause dust to get into wherein easily; Dustproof weak effect in case dust gets into frame inside, just causes machine or oil path failure easily; Thereby make troubles for the use of circular cone machine; Greatly reduce production efficiency, increased the cost of plant maintenance and maintenance, improved production cost to a certain extent.
The utility model content
The purpose of the utility model is to overcome the above-mentioned deficiency that exists in the prior art, and a kind of reasonable in design is provided, dependable performance, the frame positioner that is used for gyratory crusher of good dustproof effect.
The utility model addresses the above problem the technical scheme that is adopted: this frame positioner that is used for gyratory crusher comprises frame, frame flange and alignment pin; Be provided with the frame hole in the said frame; Be provided with the frame flange hole in the said frame flange, its design feature is: also comprise nut, the bottom of said alignment pin is provided with a circle boss; The upper end of this alignment pin is provided with external screw thread, and this external screw thread and nut are complementary; The aperture of said frame flange hole is greater than the aperture in frame hole; This frame flange hole be positioned at the frame hole under; Said set pin sleeve is contained in frame flange hole and the frame hole, and the boss in this alignment pin is arranged in the frame flange hole, and said nut is through being threaded in the upper end of alignment pin.
As preferably, the said alignment pin of the utility model is a stainless steel.
As preferably, the said nut of the utility model is a stainless steel.
The utility model compared with prior art has the following advantages and effect: simple in structure, reasonable in design, and good dustproof effect.The bottom of alignment pin is provided with a circle boss in the utility model, and promptly the lower diameter of alignment pin is big, can prevent effectively that dust from getting into frame from the bottom in frame hole, increased dustproof effect; Again since nut through being threaded in the upper end of alignment pin, the formed zone of the Outside Dimensions of nut covers the frame hole, thus can effectively prevent dust from the top in frame hole the entering frame, promoted the anti-dust performance of gyratory crusher.
Description of drawings
Fig. 1 is the structural representation that is used for the frame positioner of gyratory crusher among the utility model embodiment.
Fig. 2 is the structural representation after alignment pin amplifies among the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and through embodiment the utility model is done further to specify, following examples are to the explanation of the utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 1 to Fig. 2, the frame positioner that is used for gyratory crusher in the present embodiment comprises frame 1, frame flange 2, alignment pin 3 and nut 4, and wherein, alignment pin 3 is stainless steel with nut 4.
Be provided with the frame hole in the frame 1 of present embodiment, in frame flange 2, be provided with the frame flange hole, and the aperture of frame flange hole is greater than the aperture in frame hole.Frame flange hole in the present embodiment be positioned at the frame hole under.
The upper end y of alignment pin 3 is provided with external screw thread in the present embodiment, and this externally threaded shape all is complementary with nut 4 with size, and nut 4 can be through being threaded in the y place, upper end of alignment pin 3.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different, the above content described in this specification only is to be illustrated what the utility model structure did.Allly conceive the equivalence that described structure, characteristic and principle do according to the utility model patent and change or simple change, include in the protection domain of the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; Only otherwise depart from the structure of the utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
