Abstract
The invention relates to a lower connecting plate drilling hole drill rig of a motorcycle, comprising a base and a sliding bottom plate arranged on the base, wherein the sliding bottom plate is provided with a clamp for clamping a lower connecting plate; drill bits with different apertures are arranged above a lower connecting plate drilling hole on the stand; and the clamp comprises a positioning core rod for positioning holes at two sides of the lower connecting plate and a positioning block for positioning a hollow end surface. According to the lower connecting plate drilling hole drill rig, the lower connecting plate is arranged on the movable clamp, and the drill bits with different apertures are arranged on the drill rig, so that when the drill rig is used, a drill bit with large aperture is firstly used for drilling a hole, and the drilling hole is aligned to a drill bit with small aperture to carry out drilling by moving the clamp after drilling, and therefore, the drill bit does not need to be repeatedly replaced, or the lower connecting plate does not need to be secondarily clamped, so that processing efficiency and accuracy are high.
Description
Technical field
The present invention relates to a kind of motorcycle second line of a couplet twist drill tieholen rig, belong to the mechanical workpieces processing technique field.
Background technology
When having processing motorcycle second line of a couplet twist drill tieholen now; Often carry out through two step operations; Promptly earlier with the lower linking plate clamping on rig; Earlier use the large aperture bit bore, after having bored the large aperture drill bit is replaced to the small-bore drill bit, or lower linking plate is pulled down the new clothes of laying equal stress on be clipped on the rig that the small-bore drill bit is installed completion and hole; This kind second line of a couplet twist drill tieholen form processing drilling efficiency is low, and owing to relate to the replacement of drill bit or the clamping again of lower linking plate, owing to change the existence of joining error, the axiality of boring tieholen can not be guaranteed, and causes the generation of substandard products easily.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide the rig of a kind of high efficiency, high-precision processing second line of a couplet twist drill tieholen.
Technical scheme of the present invention is: the present invention includes base and be arranged on the sliding floor on the base, sliding floor is provided with the anchor clamps that clamp lower linking plate, and the top that is positioned at lower linking plate brill tieholen on the frame is provided with the drill bit in different apertures; Said anchor clamps comprise the location mandril of location lower linking plate two side holes and the locating piece of location hollow end face.
The base both sides are provided with the left limit push rod and the right limit push rod of restriction anchor clamps shift position.
Advantage of the present invention is: the present invention is placed on lower linking plate movably on the anchor clamps; And the drill bit in different apertures is set on rig; Use earlier the large aperture bit bore during use; Bored the back and made brill tieholen alignment apertures footpath bit bore through moving anchor clamps, so the present invention need not to replace again drill bit or secondary clamping lower linking plate, working (machining) efficiency is high, machining accuracy is high.

The specific embodiment
The present invention includes base 12 and be arranged on the anchor clamps base plate 8 on the base 12, anchor clamps base plate 8 is provided with the anchor clamps that clamp lower linking plate 16, and the top that is positioned at lower linking plate 16 brill tieholens on the frame is provided with the drill bit in different apertures; Said anchor clamps comprise the location mandril 15 of location lower linking plate 16 two side holes and the locating piece of location hollow end face.
The positioning and clamping mechanism of anchor clamps of the present invention is contained on the anchor clamps base plate 8, on base 12, moves together with anchor clamps through line slideway 11 anchor clamps base plates 8, and base about 12 is equipped with left limit push rod 10, right limit push rod 6, adds to play restriction X axle man-hour and move.Through location mandril 15 and locating piece, lower linking plate 16 is with two 2-φ, 31 holes and middle hole end surface location, and stud location plate 9 plays assist location.
The course of work of the present invention is: after lower linking plate 16 of the present invention is loaded onto anchor clamps; Pressing plate cylinder 7 drives pressing plate 5 clamping work pieces through link supporting 3, connecting rod 4; Lower linking plate cylinder 13 is pushed into right limit push rod 6 with anchor clamps simultaneously, makes φ 10.5 drill bits 1 aim at drill bit, bores φ 10.5 holes; Bored back Machinetool workpiece platform and descended, lower linking plate cylinder 13 is pulled to left limit push rod 10 with anchor clamps makes φ 8.7 drill bits 2 aim at drill bushing 14 brill φ 8.7 holes.
Claims (2)
