Description

Ultrathin axial drilling device

Technical field

The utility model relates to a kind of ultrathin axial drilling device.

Background technology

In the design of industrial products, hole on the one class part is arranged because the needs of structural design, the design attitude in hole is very special, as shown in Figure 1, processed part designs the hole that diameter is φ 6-φ 13mm on central dividing plate, the thickness range of central dividing plate is 30-60mm, and front and back position has all designed dividing plate, the structure of central dividing plate and front and back dividing plate is opened grade minimum range and only is 80mm, so the processing in this class hole is difficulty especially, as adopt conventional manufacturing process and general rig to finish, must adopt a kind of special process unit.

Summary of the invention

The purpose of this utility model is in order to solve the difficult problem on holing on front and back position all designs the central dividing plate of dividing plate, and provide a kind of ultrathin axial drilling device, this device project organization uniqueness, succinct, compact, rich creative, flexible and convenient to use, manufacturing process is good, reliable and stable, easy to maintenance, the working (machining) efficiency height.

Technical solutions of the utility model are:

Ultrathin axial drilling device comprises spindle carrier, rolling bearing, hinge wheel, minor sprocket, motor, base, chain governor motion, electric-controlled parts, drill bit, spindle carrier.The chain governor motion, motor and electric-controlled parts are assemblied on the base, electric-controlled parts links to each other with motor, be equipped with hinge wheel in the spindle carrier, minor sprocket, motor shaft links to each other with minor sprocket, link to each other by driving chain between hinge wheel and the minor sprocket, hinge wheel is assemblied on the central shaft of spindle carrier by a rolling bearing, rolling bearing axially location is located by spindle carrier and shaft-use elastic gear ring, hinge wheel is assemblied on the outer ring of rolling bearing, and the location axially is installed by the sprocket wheel location-plate, drill bit is fixed on by drill bushing on the tapering endoporus of hinge wheel, advances nut by the lock of drill bushing afterbody drill bit is locked on the hinge wheel.

The difficult point of this device is how to design drilling head, as described above, be subjected to the restriction of part to be processed structure, the overall width of drilling equipment drilling head part must be controlled in the 35mm, just can finish the processing in hole, supporting construction, drive mechanism and the drill bushing syndeton etc. that how to design the drilling main shaft in the physical dimension limited field of 35mm are innovation and creation points of the present utility model.

Characteristics of the present utility model and result of use: 1, adopted unique single rolling bearing structure designing technique, under the smear metal parameter condition that satisfies bore diameter φ 6-φ 13mm, in limited field less than the 35mm structure width, design the supporting construction of drill spindle, structural designs such as main transmission, drill bushing positioning and locking.2, project organization uniqueness, succinct, compact, rich creative, flexible and convenient to use, manufacturing process is good.3, this device uses in factory and is, and is reliable and stable, easy to maintenance, and the working (machining) efficiency height is exclusive, the proprietary technological equipment that must obligato this type of hole in piece part of processing of enterprise.
