Abstract
The utility model relates to an excavator pin shaft drilling hole tool jig which can be used for auxiliary welding of a lug plate on a pin shaft of an excavator. The jig is characterized by comprising the lug plate which is in a circular ring shape, a radial protruding rib is arranged on the outer edge of the plug plate, a limiting column perpendicular to the lug plate is fixed on the protruding rib, a first end of the limiting column is provided with a limiting pin, the cross section of the limiting pin is in a semi-oval column shape, a pair of through holes are formed on positions corresponding to the edge of the side face of the lug plate, and a connecting line of the through holes passes through the center of the lug plate. By adoption of the tool jig, not only can product quality be ensured, but also machining efficiency is high.
Description
Technical field
The utility model relates to a kind of frock clamp, is the frock clamp for pin shaft of excavator upper ear plate weld job specifically.
Background technology
At present, in field of machining, the pin shaft of excavator upper ear plate is before welding, and the operating personnel need to measure first setting-out according to the requirement at each family on otic placode, and then with the laggard pedestrian worker's welding of position alignment.Here said customer requirement refers to that bearing pin oilhole and otic placode will have the position relationship of certain angle.This operational method needs the operating personnel to have the quality that good measurement grounding in basic skills just can be guaranteed product usually, and because bearing pin of every processing all needs to carry out the measurement setting-out of repetition, working (machining) efficiency is lower.
The utility model content
Problem to be solved in the utility model provides a kind of pin shaft of excavator drilling tool anchor clamps, adopts this frock clamp, not only can guarantee product quality, and working (machining) efficiency is higher.
For addressing the above problem, take following scheme:
Pin shaft of excavator drilling tool feature of jigs of the present utility model is to comprise otic placode, and it is for having a convex tendon radially on circular and the outer.Be fixed with the limited post vertical with otic placode on the described convex tendon, the tip limited location pin of limited post, the cross section of spacer pin is half elliptic.On the relative position at edge, described otic placode side a pair of through hole is arranged, the line of through hole is through the center of otic placode.
Take such scheme, have the following advantages:
Because pin shaft of excavator drilling tool anchor clamps of the present utility model fixedly form by otic placode is vertical with limited post, the limited post tip has the spacer pin of semiellipse cylindricality, before the welding, only need the otic placode of these anchor clamps is placed on the bearing pin, so that the bearing pin oilhole is corresponding with lead to the hole site on the anchor clamps otic placode, then use alignment pin to insert location in the through hole of anchor clamps otic placode and the bearing pin oilhole.At this moment, the welding ends of bearing pin should be a little more than the bottom surface of anchor clamps upper arresting pin.Pack into behind the welding ends of again welding hole and the elliptical aperture of bearing pin otic placode being aimed at respectively bearing pin and the spacer pin of anchor clamps, just can carry out weld job this moment.When making pin shaft of excavator drilling tool anchor clamps of the present utility model, can come as required to determine the angle between the through hole line and limited post on the anchor clamps otic placode, thereby satisfy client's requirement, guarantee the quality of product; In addition, owing to use pin shaft of excavator drilling tool anchor clamps of the present utility model that bearing pin is positioned welding, need not to carry out the measurement setting-out operation of repetition, operating process is comparatively simple, thereby has greatly improved working (machining) efficiency.
Description of drawings
Fig. 1 is the structural representation of pin shaft of excavator drilling tool anchor clamps of the present utility model.
The specific embodiment
As shown in Figure 1, pin shaft of excavator drilling tool anchor clamps of the present utility model comprise otic placode 1, and otic placode 1 is circular, and a convex tendon 3 is radially arranged on its outer.Be fixed with limited post 4 on the described convex tendon 3, limited post 4 is mutually vertical with otic placode 1, the tip limited location pin 5 of limited post 4, and the cross section of spacer pin 5 is half elliptic, spacer pin 5 is coaxial with limited post 4.The line of 2, two through holes 2 of a pair of through hole is arranged through the center of otic placode on the relative position at edge, described otic placode 1 side.
During use, the otic placode 1 with these anchor clamps is placed on the bearing pin first, so that the bearing pin oilhole is corresponding with through hole 2 positions on the anchor clamps otic placode; Re-use through hole 2 and the interior location of bearing pin oilhole that alignment pin inserts the anchor clamps otic placode, at this moment, the welding ends of bearing pin should be a little more than the bottom surface of anchor clamps upper arresting pin 5; Then, pack into behind the welding ends that welding hole and the elliptical aperture of bearing pin otic placode are aimed at respectively bearing pin and the spacer pin 5 of anchor clamps, can carry out weld job.
