Description

Drilling and tapping linked power head

Technical Field

The utility model relates to an automatic change processing equipment and five metals spare part processing field, concretely relates to unit head of drilling and tapping linkage.

Background

The hardware accessories refer to machine parts or parts made of hardware and small hardware products, and can be independently used or used as auxiliary tools, such as hardware tools, hardware parts, daily hardware, building hardware, fasteners, door and window accessory hardware and the like; the five-step metal processing is to process raw materials into various parts according to the drawing or samples of customers by using machines such as lathes, milling machines, drilling machines, polishing and the like; hardware parts can provide convenience for people in daily use, but still have the following shortcomings:

in the prior art, when a piece (such as a drilling and tapping machine) to be machined by two tools is designed with automatic machining equipment or a production and machining process, the automatic machining equipment or the production and machining process can be realized only by six conventional modes:

(1) a multi-die large turntable form. 4 ~ 8 moulds are installed on a station disc, and every station unit head circumference distributes, and the part moves to each station along with the mould and processes. The processing station, empty station, feeding material returned station, clean mould station etc. of stopping have 4 ~ 8 stations generally.

(2) The multi-mould linear pushing type. 10-30 moulds are installed together in a serial connection mode (usually, the moulds are connected in a serial connection mode by chains), and power heads of each station are linearly distributed on two sides of the mould in the moving direction. And each machining station needs to perform secondary positioning on the die every time the die operates once, and the secondary positioning mechanism is not influenced by machining waste residues.

(3) The single mold is in a station mode. Usually, only 1 mould is used, and a plurality of power heads are arranged in a straight line (or a servo motor is used in cooperation with a multi-shaft gear box to output a plurality of cutter shafts to replace a plurality of power heads). The operation flow is that the mould moves to each station and corresponding cutter processing is carried out, and the mould returns to the initial point after the processing is finished in sequence. When a multi-shaft gear box is used, cutter stress and the feeding direction of the whole power head often occur.

(4) The multi-die part moving station type is adopted. The processed parts are directly (pushed by a cylinder) or indirectly (pushed and extruded by the next processed part) pushed to each station. Tooling molds for stopovers or ferries may be designed.

(5) Single mold dual station format. Usually representing only two locations for drilling and tapping. The common performance characteristics with this patent do, use servo motor and multiaxis gear box cooperation to use, export two kinds of cutters, every kind of cutter has a plurality ofly, distributes separately and installs on same straight line. The method is applied to the existing market technology, and two machining procedures are needed to be realized by translating the part. In this way, for life considerations, the hex joint between the gearbox and the output tool must be of a movable quick release construction. The reverse clearance of the structure is large, and the screw tap is not beneficial to ensuring the quality of the screw thread and the service life of the screw tap when the multi-axis tapping is carried out.

(6) And (5) manual clamping. The production and processing mode comprises two workers, two independent power heads or machine equipment, two dies, two times of clamping and one time of turnover and storage. This approach occupies both workers and the field.

In any way, the design and manufacture have the following inevitable disadvantages:

1) in a design scheme that two stations or more than three stations are required, 3-30 tooling dies are adopted by two sets of power heads and matched multi-axis devices (for drilling and tapping more than two holes);

2) the traditional power head is used, the single-gear stroke speed or the multi-stage speed is inconvenient to adjust, the depth adjustment depends on the hand feeling of workers, the intelligent numerical control is not adopted, and the traditional power head is also the main reason for slow processing beat of equipment, low comprehensive performance and over-fast productivity;

3) if the machined part can be clamped only once, the design difficulty, the cost and the production period of the automatic machining equipment can be improved by more than 50%, and the maintenance cost can be correspondingly improved by 100-300%;

4) the occupied space of the equipment is large, the equipment is inconvenient to transfer and butt joint a production line, a plurality of mechanisms and electronic elements are used, and the debugging and maintenance difficulty is large;

5) any processing parameter adjustment in production needs to be performed on all dies, the adjustment is not flexible, not quick and simple, and the requirement on a modulator worker is high;

6) the mechanism is complex, the tooling dies are multiple, the installation layers are multiple, the position error and the assembly error among a plurality of stations, the machining error, the mechanism repeated positioning error and the product secondary clamping error of each die exist, and the various types of superposed dies have great influence on the production machining precision and the maintenance and debugging of equipment;

7) for products (such as aluminum parts) which are easy to scratch, scratches can be generated on the surfaces of the parts due to multiple times of mold transfer, if the surfaces of the molds are made to be smooth, the scratches can be reduced to a certain extent, but inertia in part movement is difficult to eliminate, so that secondary positioning is inaccurate;

8) when the parts are transferred among the multiple dies, the errors of the external dimensions of the parts, the processing errors of the previous working procedure and waste residues generated by equipment processing can cause the parts to generate larger accumulated errors when being pushed from a station to a station, thereby reducing the processing precision and being difficult to debug the equipment;

when a single mold is translated, a cylinder translation mold is adopted in a general simple mode, and the two-pole position is limited by screws. Under this mode, the translation plane often piles up on the coplanar with the processing waste residue, can arouse the positioning error who dies spacing easily. Another way is to add a shaft servo motor to control the positioning position. In this way, the problem of positioning error can be solved, but the structure is complex and the cost is high.
