Description
Technical Field
The utility model belongs to the technical field of the shipbuilding, especially, relate to a large-scale boats and ships stern tube foundry goods hole processing marking device.
Background
Scribing, which is an important process in machining, is an operation of accurately scribing a machining boundary line on a workpiece surface according to the size of a pattern or an object.
Taking the ship building process as an example, in the process of machining the inner hole of the stern tube casting, a machining circular line needs to be marked by taking the center of the inner hole of the stern tube as a reference so as to finish the inner hole of the casting. The common round wire marking gauge cannot meet the requirement of the work, and the machining round wire cannot be determined according to the inner hole.
Disclosure of Invention
In order to solve the problems, the utility model aims to provide a large-scale boats and ships stern tube foundry goods hole processing marking device. The method is used for marking a circular processing line with an inner hole component, an inner hole mechanical processing reference line, a mechanical processing auxiliary line and the like, is simple to operate and can be used repeatedly.
In order to achieve the above object, the utility model adopts the following technical scheme: a large-scale boats and ships stern tube foundry goods hole processing marking device includes: the device comprises a circle center gauge, an adjusting knob, a target center sleeve, a rotary seat, a stable ring and supporting bolts, wherein a plurality of supporting bolts and holes of the adjusting knob are arranged on the stable ring, and the supporting bolts and the holes of the adjusting knob are arranged in a staggered mode; the stable ring is internally provided with a target sleeve which is sleeved on an outer ring of the rotating seat, a circle center gauge is fixed above the rotating seat, and the circle center gauge rotates in a circular track in the target sleeve through the rotating seat.
The upper edge of the seat body of the rotating seat is provided with a boss, and the boss is positioned on the target sleeve.
The fit clearance between the target eye sleeve and the rotating seat is 0.01-0.03 mm.
The utility model has the advantages that: the device is used for drawing machining round lines, inner hole machining datum lines and the like, and provides a reference for machining procedures; the operation is simple; the manufacturing cost is low, and the composite material can be repeatedly used.

Detailed Description
As shown in fig. 1 and 2, the inner hole processing and marking device for the stern tube casting of the large ship comprises: the device comprises a circle center gauge 1, an adjusting knob 2, a target center sleeve 3, a rotary seat 4, a stable ring 5 and a supporting bolt 6, wherein the stable ring 5 is provided with a plurality of supporting bolts and adjusting knob holes, and the supporting bolts and the adjusting knob holes are arranged in a staggered manner; the stable ring 5 is internally provided with a target sleeve 3, the upper edge of the seat body of the rotating seat 4 is provided with a boss, the target sleeve 3 is sleeved on the outer ring of the rotating seat 4, and the boss is positioned on the target sleeve 3. A circle center gauge 1 is fixed above the rotating seat 4, and the circle center gauge 1 rotates in a circular track in the target center sleeve 3 through the rotating seat 4. The device is fixed in an inner hole of a component by adjusting a supporting bolt of the marking device, the position of the circle center gauge is determined by adjusting the positioning of the rotary seat and the center ring by adjusting the bolt, and a circle line is drawn by the circle center gauge.
The circle center gauge 1 is a component directly used for marking; the target center sleeve 3 is used for fixing the circle center gauge 1; the target sleeve 3 is used for fixing the rotating seat 4, the fit clearance of the rotating seat and the target sleeve is 0.01-0.03mm, and the rotating seat can rotate 360 degrees in the target sleeve to realize the marking function.
The utility model relates to a large-scale boats and ships stern tube foundry goods hole processing marking device's installation, use step as follows:
1. mounting a support bolt into a bolt hole of the stable ring, and adjusting the length of a fixed bolt to ensure that the distance between two diagonal adjusting bolt nuts is basically consistent with the diameter of the inner hole of the casting to be processed;
2. mounting four adjusting knobs on the stabilizing ring, and fixing the target center sleeve in the stabilizing ring through the adjusting knobs;
3. the marking device is arranged in an inner hole of a ship stern casting to be processed, and the length of the supporting bolt is adjusted, so that the marking device is firmly fixed.
4. Installing the circle center gauge in an installation hole on the rotary seat, and locking the adjusting bolt;
5. the center of the target core sleeve is adjusted to the position specified by the processing requirement through the adjusting knob, the rotating seat provided with the circle center gauge is arranged inside the target core sleeve, and a processing circular line is scribed on the casting in a mode of rotating the circle center gauge.
