Description

Drilling machine

Technical field

The utility model belongs to the machining equipment field, particularly a kind of drilling machine of processing the shelf hole on the Chain stay of bicycle.

Background technology

The Chain stay of bicycle generally includes the vertical tube that two one ends are connected, the other end of two vertical tubes has the hook sheet, in the prior art, the Chain stay of bicycle holed add man-hour, still there is not special-purpose drilling machine, can't firmly fix the bicycle Chain stay and to its boring, thereby the processing of can't accurately holing, and cause processing quality to be affected and cause the product fraction defective to improve.

Summary of the invention

The purpose of this utility model provides a kind of special-purpose drilling machine that the Chain stay of bicycle is holed, and it can firmly fix processing work in use, boring working (machining) efficiency height.

The utility model can be implemented by the following technical programs: a kind of drilling machine, it comprises board, be fixedly installed on the hook holder on the described board, first bearing, second bearing, clamp mechanism and borehole drill construction, described clamp mechanism comprises pedestal and the cylinder that is fixedly installed on the pedestal, has back-up block on the described pedestal, has piston rod on the described cylinder, be hinged with knee on the described piston rod, one end of described knee is hinged on the described back-up block, the other end of described knee is set with pressing mold, described borehole drill construction comprises base, motor and the cutter holder that is fixedly connected on the output of described motor, be set with cutter on the described cutter holder, described pressing mold has first duty and second duty, when described pressing mold was in first duty, described pressing mold was pressed on described first bearing; When described pressing mold was in second duty, described pressing mold and described first bearing were separated.

Described hook holder comprises holder body and two thin necks that stretch out described holder body.

Compared with the prior art the utility model has following advantage: when processing bicycle Chain stay, the hook sheet of bicycle Chain stay is fixed on the hook holder, two vertical tubes of Chain stay are placed on first bearing and second bearing, the cylinder of clamp mechanism drives piston rod movement, make hinge joint be pressed on Chain stay to be processed on first bearing and between the pressing mold at the knee moving belt dynamic pressure mould on the back-up block, make that Chain stay to be processed is firmly fixed this moment, can be by borehole drill construction to its processing of holing, compared with prior art can be according to accurate boring processing, working (machining) efficiency is higher.

Accompanying drawing 2 is operated in first working state schematic representation for pressing mold of the present utility model;

Accompanying drawing 3 is operated in second working state schematic representation for pressing mold of the present utility model;

Wherein: 1, board; 2, hook holder; 3, first bearing; 4, second bearing; 5, clamp mechanism; 6, borehole drill construction; 7, pedestal; 8, cylinder; 9, back-up block; 10, piston rod; 11, knee; 12, thin neck; 13, pressing mold; 14, base; 15, motor; 16, cutter holder; 17, cutter; 18, holder body.

The specific embodiment

As accompanying drawing 1 to shown in the accompanying drawing 3, a kind of drilling machine, it comprises board 1, be fixedly installed on the hook holder 2 on the described board 1, first bearing 3, second bearing 4, clamp mechanism 5 and borehole drill construction 6, described clamp mechanism 5 comprises pedestal 7 and the cylinder 8 that is fixedly installed on the pedestal 7, has back-up block 9 on the described pedestal 7, has piston rod 10 on the described cylinder 8, be hinged with knee 11 on the described piston rod 10, one end of described knee 11 is hinged on the described back-up block 9, the other end of described knee 11 is set with pressing mold 13, described borehole drill construction 6 comprises base 14, motor 15 and the cutter holder 16 that is fixedly connected on the output of described motor 15, be set with cutter 17 on the described cutter holder 16, described pressing mold 8 has first duty and second duty, when described pressing mold 13 was in first duty, described pressing mold 13 was pressed on described first bearing 3; When described pressing mold 13 was in second duty, described pressing mold 13 was separated with described first bearing 3.

Described hook holder 2 comprises holder body 18 and two thin necks 12 that stretch out described holder body 18.

When processing bicycle Chain stay, the hook sheet of bicycle Chain stay is fixed on the thin neck 12 of hook holder 2, two vertical tubes of Chain stay are placed on first bearing 3 and second bearing 4, the cylinder 8 of clamp mechanism 5 drives piston rod 10 (relation up and down in the specification and accompanying drawing 2 to the right, relation up and down in 3 is corresponding) motion, make the knee 11 of hinge joint on back-up block 9 also move right, the pressing mold 13 that drive is arranged on knee 11 the other end moves downward, be pressed on Chain stay to be processed on first bearing 3 and between the pressing mold 13, make that Chain stay to be processed is firmly fixed, this moment, pressing mold 13 was operated in first duty, motor 15 by borehole drill construction 6 rotates feasible cutter 17 feeds that are fixed on the cutter holder 16, to being fixed on the processing of holing of Chain stay under the pressing mold 13, the processing of compared with prior art can holing more accurately, working (machining) efficiency is higher.

After the borehole drill construction 6 boring process finishing, the cylinder 8 of clamp mechanism 5 is moved to the left, make the knee 11 of hinge joint on back-up block 9 also be moved to the left, drive the pressing mold 13 that is arranged on knee 11 the other end and move upward and break away from Chain stay to be processed that this moment, pressing mold 13 was operated in second duty.

Above-described only is preferred embodiment of the present utility model, and every embodiment that does not break away from the technical solutions of the utility model content is the scope of the utility model protection.
