Description

Tool for grinding gyroscope frame pressing block

Technical Field

The utility model belongs to the technical field of fixed tools for inertial element production, and relates to a tool for fixing a pressing block when a pressing block of a gyroscope frame is ground.

Background

The gyro motor is the core part of the gyro, and a constant moment of momentum is generated by the gyro motor, so that the gyro has a gyro effect. The moment around the output shaft of the gyroscope generated by the axial displacement of the motor is considerable, so the mass center of the motor must have good stability, otherwise, the drift of the related items of the gyroscope and the acceleration is caused.

In order to avoid that the motor shaft bears larger stress and influences the stability of the mass center of the motor, the shaft hole formed by combining and processing the frame and the pressing block is designed to be in clearance fit with the motor shaft, but when in clearance fit, a clearance exists between the semicircular hole of the pressing block and the motor shaft, and the motor shaft cannot be fixed. In order to fix the motor shaft and prevent the motor shaft from displacing relative to the frame, a method of grinding the pressing block is adopted to reduce the semicircular hole of the pressing block, and the motor shaft is fixed by matching with the semicircular hole on the frame, as shown in fig. 1 and 2.

However, because the briquetting volume is less, for the special-shaped part of length width 15mm 3.3mm 8.5mm, need handheld briquetting grind the volume of going on abrasive paper, difficult operation, inefficiency, and the hand is tired easily, can't carry out continuous a large amount of grinds, has influenced production efficiency greatly. In view of this, it is necessary to improve the briquette grinding efficiency.

Disclosure of Invention

The utility model aims to provide a tool for grinding a gyroscope frame pressing block, which has scientific and reasonable design, is convenient to operate, improves grinding efficiency, reduces labor intensity, improves production efficiency and is easy to realize.

The utility model solves the technical problems by the following technical proposal:

a frock for grinding gyroscope frame briquetting, its characterized in that: including left splint, right splint and clamp plate be equipped with spacing mouth on the lower terminal surface of clamp plate, all there are left splint and right splint in the left and right sides of splint through the screw connection, spacing mouth and left splint and right splint form briquetting spacing groove jointly.

And the limiting opening is of a convex structure matched with the shape of the pressing block, and the groove depth of the pressing block limiting groove is smaller than the height of the pressing block.

And after the left clamping plate, the right clamping plate and the pressing plate are assembled into a whole, the upper end face and the lower end face of the left clamping plate, the right clamping plate and the pressing plate are all in a flush structure.

The utility model has the advantages and beneficial effects that:

this a frock for grinding gyroscope frame briquetting, during the use, fix the briquetting with this frock, then the handheld frock of rethread grinds the briquetting, has solved the difficult problem of handheld briquetting. Compared with the prior art, the utility model has simple, ingenious and reasonable structure, simple operation process during use and can greatly improve the grinding efficiency of the pressing block.

Detailed Description

The utility model is further illustrated by the following examples, which are intended to be illustrative only and not limiting in any way.

A frock for grinding gyroscope frame briquetting, its innovation lies in: including left splint 4, right splint 6 and clamp plate 5 be equipped with spacing mouth 8 on the lower terminal surface of clamp plate, spacing mouth be with the protruding font structure of briquetting 1 shape looks adaptation, all there are left splint and right splint in the left and right sides of splint through the screw connection, spacing mouth and left splint and right splint form briquetting spacing groove 7 jointly, in order to guarantee to grind the briquetting, the depth of briquetting spacing groove is less than the height of briquetting to can guarantee that the bottom of briquetting can be exposed from briquetting spacing groove.

In order to facilitate the use, operating personnel take, operate this frock, after left splint, right splint and clamp plate assembly become whole, its up end and lower terminal surface are the structure of parallel and level.

When the clamp is used, the clamp plate is placed in the middle, the left clamp plate and the right clamp plate are respectively placed on two sides of the clamp plate, and screw holes are aligned. Then the three are fixed by 4 pairs of screws and nuts, and a pressing block limiting groove matched with the pressing block in shape is formed at the lower part, as shown in fig. 4. The pressed block to be ground is placed in the block limiting groove, and the bottom of the pressed block protrudes out of the block limiting groove so as to conveniently grind the grinding surface on the pressed block. The pressing block can be ground on the sand paper or the grinding flat plate by the hand-held tool. The pressing block can be directly taken out after finishing grinding, and if the pressing block is tightly matched with a tool, the tool screw can be unscrewed, and the pressing block is taken out.

According to the difference of motor shaft 2 model, the width of the briquetting that assembles with frame 3 will be different, left splint, the tight form of right splint clamp, can adjust according to the width of briquetting to satisfy the grinding needs of different specification briquetting.

The briquetting fixing tool is simple in structure, easy to use and capable of greatly improving briquetting grinding efficiency.

Although the embodiments of the present utility model and the accompanying drawings have been disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the utility model and the appended claims, and therefore the scope of the utility model is not limited to the embodiments and the disclosure of the drawings.
