Description

Self-protection dustproof polishing kit for cecum type machine parts

Technical Field

The utility model relates to an electric power industry field of polishing, in particular to dustproof external member of polishing of self-protection to cecum type parts.

Background

At present, the equipment maintenance in the power industry usually adopts a mode of combining preventive maintenance and state maintenance. In this way, some large-scale complex system equipment cannot be completely disassembled, and the grinding treatment of partial positions can cause cross contamination to other parts. As shown in FIG. 1, the left area A cylinder and the right area B cavity are independent system components, and are not completely disassembled due to the equipment maintenance level limitation, so that a 'cecum-shaped' machine element is formed. The hole wall is ground in the hole to current grinding device direct with the head of polishing stretch into the hole, for example CN 2032458689U discloses a hole grinding device, includes: an aerodynamic device; a power conversion device; the power conversion device includes: a vent means; the rotary-vane type pneumatic motor is connected with the air hole device; the control switch is arranged on the rotary vane type pneumatic motor; the connecting shaft body is connected with the rotary vane type pneumatic motor; the main shaft is connected with the shaft body; the polishing head is arranged on the main shaft. The rotating shaft is driven to rotate by the pneumatic motor, so that the inner hole is polished by driving the polishing head to rotate, but for the blind sausage-shaped machine element shown in figure 1, when the inner wall of the area A is polished, metal dust can float to the area B to pollute equipment in the cavity.

At present, in order to prevent pollution, a dust collector is used for collecting dust outwards during polishing, and meanwhile, after polishing is completed, dust is collected in a region B. The processing mode has the disadvantages that the dust absorption pipeline and the polishing head generate cross interference during polishing and simultaneously two persons are required to finish the process synchronously. In addition, once the dust enters the area B, the dust is difficult to be sucked out completely, and the system combination parts in the area B are inevitably influenced.

Disclosure of Invention

The utility model aims to solve the technical problem that a prevent dust and polish external member of formula of protecting oneself to cecum type parts is provided, protects oneself when polishing, prevents the dust to drift to the cecum cavity.

In order to solve the technical problem, the utility model discloses a technical scheme does: the utility model provides a to blind intestines type parts from dustproof external member of polishing of protection, includes the actuating lever, and the actuating lever tip is equipped with the flabellum wheel, and the flabellum wheel outside is equipped with a plurality of flabellums, is equipped with the emery wheel on the actuating lever, and the distribution external diameter of flabellum is less than the diameter of emery wheel, and the actuating lever other end is connected with electric tool.

In a preferred scheme, the driving rod is a screw rod, and the fan impeller and the grinding wheel are provided with threaded holes matched with the screw rod.

In a preferred scheme, locking screw caps are arranged at two ends of the fan impeller and the grinding wheel and are matched with the driving rod.

In a preferred scheme, the grinding wheel is a threaded grinding wheel, the fan blades are obliquely arranged, and the inclination direction of the fan blades is consistent with the thread direction of the grinding wheel.

The utility model provides a pair of to dustproof external member of polishing of self-protection formula of cecum type parts has following beneficial effect:

1. a unified power source is adopted, the fan impeller and the grinding wheel are driven simultaneously, the fan impeller rotates to form a retaining wall, and dust is prevented from flying to the caecum cavity.

2. Simple structure, the equipment is convenient, can be according to the position of the point of polishing, installs fan wheel in different positions, and the relative position of fan wheel and emery wheel can be adjusted in a flexible way, can realize blowing and inhaling of the dust of polishing.

3. The fan impeller forms wind pressure, and the fan impeller is matched with an air duct on the surface of the grinding wheel to assist dust to move outwards.

Drawings

The invention is further described below with reference to the accompanying drawings and examples:

FIG. 1 is a schematic view of a caecum-type machine member;

FIG. 2 is a schematic view of the overall structure of the present invention;

FIG. 3 is a schematic view of the mounting of the grinding wheel;

FIG. 4 is a schematic view of a fan wheel configuration;

in the figure: the device comprises a driving rod 1, a fan wheel 2, a grinding wheel 3, a lock nut 4 and fan blades 201.

Detailed Description

As shown in fig. 2 to 4, a self-protection dustproof grinding kit for a blind intestine type machine member includes a driving rod 1, an impeller 2 is disposed at an end of the driving rod 1, a plurality of blades 201 are disposed outside the impeller 2, a grinding wheel 3 is disposed on the driving rod 1, a distribution outer diameter of the blades 201 is smaller than a diameter of the grinding wheel 3, the other end of the driving rod 1 is connected with an electric tool, and the electric tool can be a drilling machine or a motor.

When the electric tool clamp is used specifically, the end part of the driving rod 1 is installed on the electric tool clamp, one electric tool drives the fan wheel 2 and the grinding wheel 3 simultaneously, the distributed outer diameter of the fan blades 201 is smaller than the diameter of the grinding wheel 3, the grinding pipe wall cannot be damaged, the fan wheel 2 rotates to form a retaining wall, dust is prevented from drifting towards a cecum cavity, and meanwhile the fan wheel 2 forms wind pressure to assist the dust to move outwards in a synergistic manner.
