Abstract

The purpose of this utility model is to provide a kind of special tooling equipment for drilling processing that can process multi-standard parts quickly, efficiently, conveniently and at low cost with a set of drilling templates without replacing the drilling templates and drill sleeves. The drilling mold provided by the utility model includes a drilling mold base (1), a positioning screw (2), a drill sleeve (3), a bushing (4), a bracket A (6), a movable connecting rod (7), and a nut (8) , ejector rod (9), support B (10), etc., the drill sleeve (3) is installed on the drill base, positioned and pressed by the set screw (2). A plurality of drill guide holes and a plurality of positioning holes are processed on the drill sleeve (3), and each guide hole corresponds to a processed part of a specification. When processing parts, rotate the drill sleeve, just rotate the guide hole of the corresponding specification to the axis of the drill base, and then use the positioning screw to position and compress the drill sleeve, and then the parts can be processed.

Description

A special tooling equipment for drilling

technical field

The utility model relates to mechanical processing equipment, in particular to a special tooling equipment for drilling.

Background technique

Drilling on a cylindrical surface with a small curvature, especially when the number of parts to be processed is large, in order to ensure the processing quality and improve production efficiency, the processing of such holes generally requires the use of drilling templates. Drilling jigs belong to special tooling, and usually only parts corresponding to their specifications can be processed. If there are many specifications of parts, multiple sets of drilling jigs are required. Problems such as cumbersome management in the use of drilling jigs.

Contents of the invention

The purpose of this utility model is to provide a kind of special tooling equipment for drilling processing that can process multi-standard parts quickly, efficiently, conveniently and at low cost with a set of drilling templates without replacing the drilling templates and drill sleeves.

The drilling mold provided by the utility model includes a drilling mold base (1), a positioning screw (2), a drill sleeve (3), a bushing (4), parts to be processed (5), a bracket A (6), and a movable connecting rod (7), nut (8), ejector rod (9), bracket B (10), etc., see Figure 1 for details.

The drill sleeve (3) is installed on the mold base, and is positioned and pressed by the set screw (2). After the parts to be processed are put into the mold base (1), they are tightened by the push rod (9). A plurality of drill guide holes and a plurality of positioning holes are processed on the drill sleeve (3), and each guide hole corresponds to a machined part of a specification. When processing parts, rotate the drill sleeve, just rotate the guide hole of the corresponding specification to the symmetrical central axis of the drill base, then use the positioning screw to position and compress the drill sleeve, install the processed part, rotate the movable connecting rod and place one end of it Fasten it on the annular groove of bracket B, rotate the mandrel to clamp the processed part, and then the part can be processed.

Drilling template seat (1) is the main body of this cover drilling template, and all functional parts are all installed on it.

The function of the positioning screw (2) is to locate and clamp the drill sleeve, and its structure is a combination of a positioning surface and a thread to realize quick positioning and clamping of the drill sleeve. This part is connected on the drilling mold base (1) by thread.

The function of the drill sleeve (3) is to guide the drill bit to process the workpiece.

The function of bracket A (6), bracket B (10) and movable connecting rod (7) is to support the ejector rod (9), so as to ensure that the ejector rod (9) clamps the processed parts during processing, and the bracket is threaded on the drilling mold seat (1).

The utility model provides a fast, efficient and convenient drilling mold for drilling parts with multiple specifications. The biggest difference between this jig and ordinary jigs is that ordinary jigs can only process parts of one specification, while this jig can process parts of multiple specifications with one set of jigs. The key to realizing the above functions is that the drill sleeve is provided with a plurality of drill guide holes corresponding to the size requirements of the processed parts, and the positioning screw adopts the structure combining the positioning surface and the connecting thread, so that the drill sleeve can be quickly positioned and clamped. .

Fig. 2 is the structural representation of the drill sleeve (3) of the special tooling equipment for drilling described in the utility model.

Fig. 3 is a schematic diagram of parts processed by the utility model.

6. Specific implementation

To process parts of the type shown in Figure 3, the dimensions L and Lh have multiple specifications, and the other dimensions are the same. When working, first loosen the positioning screw, rotate the drill bushing according to the Lh size of the workpiece to be processed (the drill bushing can be taken out if necessary), and rotate the position of the corresponding guide hole on the drill bushing to the symmetrical center axis of the drilling mold, and then Tighten the set screw in place. Then put the workpiece to be processed into the mounting hole of the drilling mold as shown in Figure 1, rotate the movable connecting rod, and clamp it on the bracket B, and then rotate the ejector rod until the workpiece is pushed to death, so as to ensure that the round end surface of the workpiece step is closely fitted and positioned Surface B, at this time, adjust and fix the position of the drilling mold relative to the drilling machine, and then process it.

If you want to process parts of other specifications, just repeat the above operation.

Claims (2)
