Description

Composite positioning bolt

Technical Field

The utility model belongs to the technical field of positioning bolt, concretely relates to compound positioning bolt.

Background

European edition jaw breaker wide application is in trades such as metallurgy, mine, building, and mainly used broken materials such as ore, granite, because the machine service condition is abominable, consequently if can not guarantee to the condition of its important part accurate positioning, then lead to the relatively poor problem of machine operating stability and sturdiness easily, current to the problem that important part can't fix a position with the mode that perfectly agrees with in the operation process, can not effectual the solution, so need the improvement design of pertinence.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a compound positioning bolt comes into operation to it can't fix a position with the mode that perfect agrees with to propose important part in solving above-mentioned background art, leads to influencing the problem of machine steady operation easily.

In order to achieve the above object, the utility model provides a following technical scheme: composite positioning bolt, including connecting the bolt, one side fixed mounting who connects the bolt has the connecting block, it is equipped with the sleeve to connect bolt and connecting block interpolation, the sleeve interpolation is equipped with the bolt, and a pot head of bolt is equipped with the fixed block.

Preferably, the sleeve is internally provided with a conical section matched with the bolt.

Preferably, the size of one end of the bolt far away from the fixing block is larger than that of the other end of the bolt.

Preferably, the surface of one end, far away from the sleeve, of the bolt is provided with threads, an internal thread is formed in the fixing block, and the bolt is in threaded connection with the fixing block.

Preferably, a limiting ring is arranged on the surface of one end, far away from the connecting bolt, of the sleeve.

The utility model discloses a technological effect and advantage: this compound positioning bolt uses through the cooperation of connecting block, sleeve, bolt and fixed block, can make organism frame and steel sheet stable installation in the European edition of jaw breaker, improves the stability of machine operation and the tightness of part, guarantees that the machine can operate the work often by high efficiency.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. 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.

The utility model provides a compound positioning bolt as shown in fig. 1-3, including connecting bolt 1, one side fixed mounting of connecting bolt 1 has connecting block 2, and the interpolation of connecting bolt 1 and connecting block 2 is equipped with sleeve 3, and the interpolation of sleeve 3 is equipped with bolt 4, and a pot head of bolt 4 is equipped with fixed block 5.

Firstly, the device is inserted into a hole groove formed by a machine body frame and a steel plate, then the fixing block 5 is twisted, the fixing block 5 is rotated to drive a bolt 4 to slide, along with the sliding of the bolt 4, the sleeve 3 which conflicts with the bolt is expanded and opened, the sleeve 3 is completely attached to the machine body frame and the hole groove formed by the steel plate, the conflict is more stable, at the moment, one end of the sleeve 3 is clamped on the surface of the steel plate, the sleeve is fixed, then, the connecting bolt 1 is twisted to drive the connecting block 2 to slide on the sleeve 3, so that the connecting block 2 can conflict with the surface of the machine body frame, the stable fixing work between the upper part and the lower part can be completed, at the moment, the perfect conjunction of the important parts such as the upper round pipe and the lower round pipe in the running process of the European jaw crusher can be realized, the running stability of the machine and the firmness of the parts can be improved, and the high-efficiency normal running work of the European jaw crusher can be improved, the use effect is increased.

Set up in the sleeve 3 to the toper cross-section with bolt 4 matched with, set up to the toper cross-section through setting up in the sleeve 3 to can make bolt 4 progressively slide to sleeve 3, the inseparable laminating of the sleeve 3 of being convenient for and bolt 4 makes sleeve 3 progressively open, the hole groove that follow-up adaptation organism frame of being convenient for and steel sheet were seted up.

Bolt 4 keeps away from the one end size of fixed block 5 and is greater than the other end, when bolt 4 inserts in the sleeve 3, it is less through its one end size, can make its stable slide in sleeve 3, thereby make sleeve 3 obtain the extension, later when the great one end of bolt 4 size is contradicted in the sleeve 3, thereby accomplish bolt 4 and sleeve 3's stable fixed, make sleeve 3's extension degree obtain the restriction, avoid influencing the device normal use's condition because of the extension is great.

Bolt 4 is provided with the screw thread far away from sleeve 3's one end surface, has seted up the internal thread in the fixed block 5, and bolt 4 links to each other with 5 screw threads of fixed block, through wrench movement fixed block 5, because bolt 4 links to each other with 5 screw threads of fixed block to can make inserting that bolt 4 can fasten more locate sleeve 3 in, be convenient for its follow-up extension that drives sleeve 3.

Sleeve 3 keeps away from the one end surface mounting who connects bolt 1 has the spacing collar, after sleeve 3 inserted the hole groove that body frame and steel sheet were seted up, adjust through bolt 4 and make sleeve 3 extension open, make the installation of the spacing collar of sleeve 3 one end this moment to can make the spacing collar conflict steel sheet, be convenient for follow-up completion is to the stable fixed processing of body frame and steel sheet, make the upper and lower pipe department of European edition jaw broke obtain accurate location, the follow-up work of carrying on of being convenient for.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the principles of the present invention.
