Abstract
The utility model relates to a drilling rig for drilling holes of a lower link plate of a motorcycle. The drilling rig comprises a base seat and a sliding base plate arranged on the base seat, wherein, a fixture for clamping the lower link plate is arranged on the sliding base plate; drilling bits with different hole diameters are arranged on a frame and positioned above the drilling holes of the lower link plate; and the fixture comprises positioning mandrels for positioning two side holes of the lower link plate and a positioning block for positioning a hollow end surface. According to the drilling rig, the lower link plate is placed on the movable fixture, and the drilling bits with the different hole diameters are arranged on the drilling rig; when the drilling rig is in use, holes are firstly drilled by using the drilling bit with the large hole diameter; and after the holes are drilled, the drilling holes are aligned with the drilling bit with the small hole diameter to be drilled by moving the fixture, so that after using the drilling rig, re-replacement of the drilling rigs or twice clamping of the lower link plate is not required, so that the processing efficiency and the processing precision are high.
Description
Technical field
The utility model relates to a kind of motorcycle second line of a couplet twist drill tieholen rig, belongs 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.
The utility model content
The utility model is to above-mentioned defective, and purpose is to provide the rig of a kind of high efficiency, high-precision processing second line of a couplet twist drill tieholen.
The technical scheme of the utility model is: the utility model comprises base and is arranged on the sliding floor on the base, and sliding floor is provided with the anchor clamps that clamp lower linking plate, is positioned at the drill bit that top that lower linking plate bores tieholen is provided with different apertures on the frame; 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.
The utility model has the advantages that: the utility model 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 utility model 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 utility model comprises base 12 and is arranged on the anchor clamps base plate 8 on the base 12, and anchor clamps base plate 8 is provided with the anchor clamps that clamp lower linking plate 16, is positioned at the drill bit that top that lower linking plate 16 bores tieholens is provided with different apertures on the frame; 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 the utility model anchor clamps 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 utility model is: after the utility model lower linking plate 16 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.
