Description

A device for detecting tiny slots on a gyroscope frame

Technical Field

The utility model belongs to the technical field of high-efficiency and high-precision detection, in particular to a detection method and tooling for tiny slots on a gyroscope frame.

Background Art

In the field of inertial navigation, the liquid-floating gyroscope frame (Figure 1 shows a schematic diagram of the three-dimensional structure of the liquid-floating gyroscope frame) is a typical complex component and a key workpiece in the liquid-floating gyroscope. Since the frame is the main installation body of the gyroscope components, in order to ensure that the wiring is installed in place without damage, the requirements for the tiny wire grooves and wire holes on the surface are high, especially the transition between the two. No burrs or sharp corners are allowed under the premise of meeting the dimensional accuracy.

Small diameter milling cutters are usually used when processing various frame wire ducts. Due to the large batch size of workpieces, tool wear often causes quality problems such as excessive burrs, unclear roots, and sharp corners at transitions, which lead to scrapped workpieces. The current detection method is to directly detect the tiny slots of the liquid floating gyroscope with the eye or with a magnifying glass. The current detection method has the disadvantages of low detection efficiency and poor detection accuracy.

The base is a block-shaped structure as a whole, and its bottom surface is a positioning surface, which contacts with a base such as a desktop, and can provide a stable support force for the device. A limited platform is arranged at the left part of the upper end, and the upper end surface of the limited platform is a limited surface 1.1. A positioning hole 1.2 is arranged on the limited platform, which cooperates with the microscope guide frame to limit the axial movement of the guide frame. A lower guide rail 1.3 extending in the front-to-back direction is arranged in the middle right part of the upper end, which cooperates with the lower part of the cross slide to realize the movement of the cross slide in the front-to-back direction.

The lower end of the cross slide is provided with a lower sliding groove 8.1 extending in the front-to-back direction, and the upper end of the cross slide is provided with an upper raised guide rail 8.2 extending in the left-to-right direction. The lower sliding groove and the lower guide rail of the base can form a guiding match in the front-to-back direction, and the upper raised guide rail can form a guiding match in the front-to-back direction with the workpiece mounting table.

The lower end of the workpiece mounting table is provided with an upper slide groove 7.2 extending in the left and right directions, which can form a guiding match with the upper raised guide rail on the cross slide. In order to accommodate the placement of workpieces of different sizes, a circular positioning groove 7.1 is designed above the workpiece mounting table, which can cooperate with the workpiece limiting sleeve 6 (as shown in Figure 5). This arrangement is convenient for replacing the workpiece limiting sleeve with a simpler structure when facing the inspection of workpieces of different sizes, without directly replacing the workpiece mounting table with a more complex structure and more difficult to process. The inner hole of the workpiece limiting sleeve can be designed according to the size of the workpiece.

The microscope rail bracket is composed of a positioning cylindrical part 3.2 and an L-shaped bracket part 3.3. The positioning cylindrical part is vertically fixedly connected to the lower end of the horizontal side of the L-shaped bracket part. The positioning cylindrical part cooperates with the positioning hole on the base. An internal tightening thread 3.1 is provided on the positioning cylindrical part, which can cooperate with the countersunk hole at the bottom of the base and the tightening screw for tightening. A guide long hole 3.4 is provided on the vertical side of the L-shaped bracket part in the up-down direction. By inserting a screw in the guide long hole, an adjustable fixed connection of the microscope fixing bracket in the up-down direction is realized.

The microscope fixing bracket is composed of a fixing sleeve 4.2 and a fixing column 4.4 vertically connected to the outer cylindrical surface of the fixing sleeve. The inner circular hole of the fixing sleeve is fitted with the outer tube of the microscope. A radial threaded hole 4.1 is provided on the fixing sleeve on one side relative to the fixing column. By installing a radial locking screw 2 in the radial threaded hole, the microscope can be pressed and fixed on the microscope fixing bracket. A central threaded hole 4.3 is provided on the fixing column, which is connected to the screw passing through the guide long hole on the above-mentioned microscope guide rail bracket to achieve an adjustable fixed connection with the microscope guide rail bracket.

3. Insert the positioning cylindrical part of the microscope rail bracket into the positioning hole on the base, and use the tightening screw to achieve the fixed connection between the microscope rail bracket and the base (there is a countersunk hole below the positioning hole of the base, so after the microscope rail bracket is locked, the screw cap will not be exposed from the bottom of the base). As shown in Figure 10.

4. Fit the microscope fixing bracket with the guide long hole through the positioning cylinder and fix it with screws. Place the microscope in the fixing bracket and fix it with the radial locking screw through the threaded hole at one end of the fixing bracket, as shown in Figure 1.
