Abstract
The utility model relates to a tool for scribing at the center of a rudder shaft. Positioning shaft self-positioning devices and rudder shaft self-positioning devices are respectively arranged at the front end and the rear end of the upper surface of a connecting base plate; and an axis of a positioned positioning shaft is mutually vertical to an axis of the positioned rudder shaft. The tool for scribing at the center of the rudder shaft is simple in structure, and accurate in positioning, so that the production efficiency and the product quality of scribing working procedures of the rudder shaft are improved.
Description
Technical field
The utility model relates to a kind of rudderpost center scribing tooling, belongs to a kind of auxiliary mould.
Background technology
As everyone knows, mark the boundary of processing according to drawing requirement on workpiece, be called line.Line work is an important step in machining.Scoring tool commonly used is face plate, height gauge, scriber etc., but common tool can not meet the requirement of some line work sometimes, needs to complete by other equipment or special tooling.
In the past, in not design, when making rudderpost center scribing tooling, the center line of rudderpost was drawn by dividing head, and take the cylinder of part as the clamping benchmark, the rudderpost center is marked at the center of the stepped hole of centering front portion.This rudderpost center is when general assembly, and the center of whole body is to determine according to the center line of rudderpost, if the center line of rudderpost is inaccurate, directly affects total packing quality of whole body.Due to the many factors such as foozle of rudderpost, it is inaccurate that the center line of rudderpost is drawn sometimes, thereby when affecting general assembly, the center of whole body is determined.Therefore, the general assembly factory troubleshooting of once repeatedly sending someone causes the waste of manpower and materials, has also had a strong impact on manufacturing schedule, and simultaneously, the production efficiency of crossed process is lower.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of rudderpost center scribing tooling, and this rudderpost center scribing tooling is simple in structure, and accurate positioning, thereby has improved production efficiency and the product quality of rudderpost crossed process.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of rudderpost center scribing tooling, upper surface rear and front end at connecting bottom board is respectively equipped with locating shaft self locating device and rudderpost self locating device, and the locating shaft axis behind the location with locate after the rudderpost axis mutually vertical.
The structure of locating shaft self locating device is, is arranged with connected positioning plate at connecting bottom board upper surface one end, is flexibly connected connecting plate on connected positioning plate, is provided with respectively little V-block at the inner end of each connecting plate, and the center of two little V-blocks point-blank; The structure of rudderpost self locating device is, is provided with large V-block at the center of the other end of connecting bottom board upper surface, and the axis of large V-block is vertical with the straight line of two little V-blocks formation.
The upper surface of described connecting bottom board is provided with the T connected in star, is respectively equipped with bolt in the bottom surface of two connected positioning plates and large V-block, and bolt is separately positioned in corresponding T connected in star.
The both sides of described large V-block are flexibly connected inverted U-shaped and connect bracing frame, the upper end central authorities that connect bracing frame are provided with pressing handle, pressing handle is connected with compact heap after passing the connection bracing frame by screw thread, the lower surface of compact heap is provided with inverted V-shaped groove, and its center line and large V-block are point-blank.
This large V-block in scribing tooling one, the place ahead of employing, rudderpost center, the structure of two the little V-blocks in rear can solve the problem of bad location in the rudderpost scratching process, simultaneously because V-shaped groove has self-centering function, so centering is accurately time saving and energy saving, has greatly improved operating efficiency.
Also be provided with the compact heap that compresses by pressing handle simultaneously above large V-block, thereby the orientation problem in the scratching process of avoiding avoids occurring error.

The specific embodiment
As shown in Figure 1 to Figure 3, a kind of rudderpost center scribing tooling is respectively equipped with locating shaft self locating device 10 and rudderpost self locating device in the upper surface rear and front end of connecting bottom board 1, and the locating shaft axis behind the location with locate after the rudderpost axis mutually vertical.
The structure of locating shaft self locating device 10 is, be arranged with connected positioning plate 3 at connecting bottom board 1 upper surface one end, be flexibly connected connecting plate 4 on connected positioning plate 3, at center that the inner end of each connecting plate is provided with respectively 12, two little V-blocks 12 of little V-block point-blank; The structure of rudderpost self locating device is, is provided with large V-block 6 at the center of the other end of connecting bottom board 1 upper surface, and the axis of large V-block 6 is vertical with the straight line of two little V-blocks 12 formation.
The upper surface of described connecting bottom board 1 is provided with the T connected in star, is respectively equipped with bolt 2 in the bottom surface of two connected positioning plates 3 and large V-block 6, and bolt 2 is separately positioned in corresponding T connected in star.
The both sides of described large V-block 6 are flexibly connected inverted U-shaped and connect bracing frame 8, the upper end central authorities that connect bracing frame 8 are provided with pressing handle 10, pressing handle 10 is connected with compact heap 9 after passing connection bracing frame 8 by screw thread, the lower surface of compact heap 9 is provided with inverted V-shaped groove, and its center line and large V-block 6 are point-blank.
When rudderpost was rule, the column part of rudderpost was placed in the V-type groove of large V-block 6, and locating shaft 7 passes the structure hole of rudderpost, was placed in the V-type groove of little V-block 12, and passed through compact heap 9 workpiece pressings, thereby mark the center line of rudderpost.
