Description

Grinding device of adjustable diameter of polishing

Technical Field

The utility model relates to an equipment field of polishing, in particular to adjustable diameter of polishing's grinding device.

Background

Modern elevators are mainly composed of a traction machine (winch), guide rails, a counterweight, safety devices (such as a speed limiter, a safety gear, a buffer and the like), a signal control system, a car, a hall door and the like. These parts are installed in the hoistway and machine room of the building, respectively. Usually, a steel wire rope is used for friction transmission, the steel wire rope bypasses a traction sheave, two ends of the steel wire rope are respectively connected with a car and a balance weight, and a motor drives the traction sheave to lift the car. The elevator requires safety and reliability, high conveying efficiency, accurate leveling, comfortable riding and the like.

Motor and speed reducer part need be used to the elevator motor housing, and motor housing comprises fore-stock, frame and chassis again, like the fore-stock that FIG. 1 shows, punch at the center of fore-stock and be called the centre bore, need polish after the trompil again, and because the aperture size of centre bore is different, need replace different grinding tool to different apertures during polishing, lead to processing loaded down with trivial details.

SUMMERY OF THE UTILITY MODEL

The utility model provides an adjustable grinding diameter's grinding device to solve prior art and need replace different aperture grinding tool's problem to different apertures.

In this scheme, an adjustable diameter of polishing's grinding device, including base and circular shape expansion ring, be equipped with the bull stick on the axis of base, the bull stick is connected with its pivoted motor of drive, and motor and base fixed connection, the equipartition has a plurality of connecting holes on the bull stick, many telescopic links of inboard fixedly connected with of expansion ring, and the telescopic link can be dismantled with the connecting hole and be connected, and the expansion ring includes many solid arc poles and many cavity arc poles, solid arc pole and cavity arc pole staggered connection, and solid arc pole runs through the cavity arc pole, the outer cambered surface of cavity arc pole can be dismantled and be connected with the head of polishing.

The working principle and the beneficial effects of the scheme are as follows: during the use, according to the aperture of centre bore, the degree of depth that the solid arc pole of adjustment inserted cavity arc pole, the diameter of adjustment expansion ring, the length of later adjustment expansion link for the telescopic link can insert in the connecting hole, and the length of fixed expansion link later puts into the hole that needs polished with the device, fixes base and frame, opens the motor, and the bull stick rotates, and expansion ring and the head of polishing rotate thereupon, can begin to polish. The device in this scheme only needs the diameter of adjustment expansion ring, and the length of adjustment expansion rod fixes the telescopic link in the connecting hole, can polish to the centre bore in different apertures.

Further, the telescopic link includes stiff end and flexible end, and the stiff end passes through bolt fixed connection with flexible end. The length of the telescopic rod is convenient to adjust, and the telescopic rod is fixed through the bolts and is more stable.

Further, the rotating rod is an air cylinder. Set up the bull stick into the cylinder, be convenient for adjust the length of bull stick, if the higher adjustment bull stick height in the hole height that needs to polish, make the bull stick lengthen can, if the hole height that needs to polish is lower when, with the bull stick shorten can.

Furthermore, the telescopic link includes four, four telescopic link mutual symmetry. Four telescopic rods are arranged to enable the telescopic rings to be fixed more tightly.

Furthermore, the outer arc surface of the hollow arc-shaped rod is fixedly connected with a connecting block, a fixing hole is formed in the connecting block, and the polishing head is fixedly connected with the fixing hole through a bolt. Thus, a plurality of polishing heads can be arranged to polish the connecting hole together.

Further, the hollow arc-shaped rod and the solid arc-shaped rod are both made of flexible materials. So as to form a telescopic ring.
