Description

Step shaft pin for turntable

Technical Field

The utility model relates to a step pivot for carousel belongs to auxiliary assembly technical field for the powder carousel.

Background

At present, a hole on a rotary table 1 (shown in figure 1) and a shaft pin 2 (shown in figure 2) are in tight fit with the shaft pin 2, the sizes of the holes on a plurality of layers of partition plates of the rotary table 1 are the same, the sizes of the shaft pin 2 and the rotary table 1 are also consistent, after the shaft pin 2 is used for one end, under the action of high stress and impact load, the position of a shaft pin hole on the rotary table 1 is abraded and is positioned in a dust process, particularly when the rotary table 1 and the shaft pin 2 need to be replaced, the shaft pin 1 and the rotary table 2 are almost integrated, the shaft pin 1 and the rotary table 2 are difficult to disassemble smoothly, and much inconvenience is brought to maintenance and replacement.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the technical problem that above-mentioned background art mentioned, and adopt following technical scheme to realize:

step pivot is used to carousel, including carousel and pivot, carousel and pivot pass through the tight fit and connect, be equipped with a plurality of baffles on the carousel, every all be equipped with the axle pinhole on the baffle, and the aperture from the axle pinhole on the baffle at the top place of carousel to the axle pinhole on the baffle at carousel bottom place reduces in proper order, the pivot includes a plurality of axles, and a plurality of axles reduce in proper order from the top down the aperture, every the diameter of the axle from the top down on the axle corresponds in proper order with the axle pinhole of baffle from the top down.

As a preferred example, the number of the shaft pin holes is four, two shaft pin holes are arranged on the partition plate positioned at the bottommost part of the rotary table, the diameters of the two shaft pin holes are sequentially reduced from top to bottom on the partition plate positioned at the bottommost part of the rotary table, and the two shaft pin holes are communicated with each other; the number of the shafts on the shaft pins is four, and the four shafts correspond to the four shaft pin holes.

As a preferred example, the top of the shaft positioned at the top of the rotary table is provided with a hoisting hole.

The utility model has the advantages that: the device is mainly convenient to disassemble and assemble, saves time and lightens labor intensity, thereby better reducing maintenance time and improving maintenance efficiency.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1-4, carousel 1 is with step pivot 2, including carousel 1 and pivot 2, carousel 1 and pivot 2 are connected through tight fit, be equipped with a plurality of baffles on the carousel 1, all be equipped with axle pinhole 3 on every baffle, and the aperture of axle pinhole 3 on the baffle from the top of carousel 1 place to the baffle of carousel 1 bottom place reduces in proper order, pivot 2 includes a plurality of axles 4, and a plurality of axles 4 reduce in proper order from the top down aperture, the diameter of axle 4 from the top down on every pivot 2 corresponds in proper order with baffle from the top down axle pinhole 3.

The number of the shaft pin holes 3 is four, two shaft pin holes 3 are formed in the partition plate located at the bottommost part of the rotary table 1, the diameters of the two shaft pin holes 3 are sequentially reduced from top to bottom on the partition plate located at the bottommost part of the rotary table 1, and the two shaft pin holes 3 are communicated; the number of the shafts 4 on the shaft pin 2 is four, and the four shafts 4 correspond to the four shaft pin holes 3.

The top of the shaft 4 positioned at the top of the turntable 1 is provided with a hoisting hole.

The working principle is as follows: at first, the lifting hole on the shaft 4 positioned at the top of the turntable 1 is hooked through the hook on equipment such as a travelling crane, so that the shaft pin 2 positioned on the shaft pin hole 3 on the clapboard at the bottommost part of the turntable 1 is loosened (the diameter of the shaft 4 at the position is compared with the diameter of other shafts 4 on the device and is the minimum diameter), then the hook on the travelling crane is started, so that the shaft pin 2 is hooked through the hook, the whole shaft pin 2 can be smoothly detached, the maintenance time is greatly reduced, and the maintenance efficiency is improved.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
