Description

Technical Field

[0001] The utility model relates to the technical field of bucket teeth, in particular to a bucket tooth locking device. Background Art

[0002] Excavator bucket teeth are important components of the excavator, similar to human teeth, and are also wearing parts. They are combined bucket teeth consisting of a tooth seat and a tooth tip, which are connected by a pin shaft. Since the part of the bucket tooth that fails due to wear is the tooth tip, you only need to replace the tooth tip.

[0003] Bucket teeth are generally fixed by locating pins during installation, but the locating pins are prone to come off after long-term use, causing the bucket teeth to be lost. At the same time, the locating pins can only fix the bucket teeth horizontally during installation, but not vertically, resulting in poor fixing effect. Therefore, a bucket tooth locking device is urgently needed to overcome the above defects. Summary of the invention

[0004] The utility model aims to provide a bucket tooth locking device with good fixing effect to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bucket tooth heterogeneous locking device, including a tooth seat, a positioning assembly, a bucket tooth assembly and a locking assembly, the positioning assembly is arranged on the left side of the tooth seat, the bucket tooth assembly is arranged on the left side of the positioning assembly, and the locking assembly is arranged on the back side of the tooth seat, the positioning assembly includes a positioning seat, a positioning slide rod, a positioning groove, a through hole, a slider, a spring and a slide groove, the bucket tooth assembly includes a tooth tip body, an annular groove, a heterogeneous groove and a limit groove, the locking assembly includes a positioning pin, a limit nut and a threaded groove, the through hole is opened inside the positioning seat, the positioning grooves are opened on both sides of the through hole, the positioning slide rod is arranged inside the positioning groove, and the heterogeneous grooves are opened on both sides of the inner cavity of the tooth tip body.

[0006] Furthermore, the limiting grooves are both opened at the top and bottom of the inner cavity of the tooth tip body, and the annular grooves are both opened at the front and back of the inner cavity of the tooth tip body.

[0007] Furthermore, the right side of the positioning seat is fixedly connected to the left side of the gear seat, and the sliding grooves are both opened on both sides of the positioning groove.

[0008] Furthermore, the sliding block slides inside the sliding groove, and a relatively close side of the sliding block is fixedly connected to two sides of the positioning sliding rod.

[0009] Furthermore, a spring is fixedly installed in the inner cavity of the slide groove and on a side relatively close to the sliding block, and the threaded groove is provided on the surface of the positioning pin.

[0010] Furthermore, the limiting nut is arranged on the front side of the positioning pin, and mounting holes are provided on the top and the bottom of the gear seat.

[0011] In summary, due to the adoption of the above technology, the beneficial effects of the utility model are:

[0012] The utility model mainly fixes the bucket tooth assembly by setting a positioning component, and mainly locks and fixes the connection between the positioning component and the bucket tooth assembly by setting a locking component, thereby further improving the connection strength between the two. During installation, the staff first sets the tooth tip body on the surface of the positioning seat, and then penetrates the positioning pin into the inner cavity of the through hole through the annular groove. Under the action of the positioning pin, the positioning slide bar drives the slide bar to move to both sides, and then the positioning slide bar penetrates into the interior of the tooth tip body through the limiting groove, thereby fixing the tooth tip body longitudinally. Finally, it is only necessary to install the limiting nut on the surface of the positioning pin to fix it. The utility model has the advantage of good fixing effect, and solves the problem that the bucket tooth is generally fixed by the positioning pin during installation, but the positioning pin is easy to come off the pin after long-term use, thereby causing the bucket tooth to be lost. At the same time, the positioning pin can only fix the bucket tooth horizontally during installation, and cannot fix it longitudinally, resulting in poor fixing effect.
