Abstract

The utility model provides an assistant electric drill support for face-upward drilling; wherein, a four-bar linkage comprising an upper pole support, an elevating lever, a connecting plate and a handle support; the upper pole support and the handle support are respectively hinged with the two ends of the connecting plate; the central section of the elevating lever is hinged with the top end of the handle support; a control handle is arranged at the lower end of the handle support; a retractable lower pole support is sleeved at the bottom of the upper pole support; a base is positioned at the root of the lower pole support; a forked type fixture for the electric drill is arranged at the top part of the elevating lever; a pressing board is positioned above the forked type fixture for the electric drill, and tightly locked by two nuts. The utility model has the advantages that: due to downward force is changed into an upward pressure for the electric drill through the four-bar linkage, the operators are far away from the lower part of the electric drill, so as to prevent aluminum scraps doing harms to the human body.

Description

Face upward and bore auxiliary Electric drill support

Technical field

The utility model discloses a kind of facing upward and bores auxiliary Electric drill support, and a kind of electric drill aid is provided, and belongs to the machine tools technical field.

Background technology

In the actual production, when the electric drill up-hole, the people need stand under the electric drill, electric drill is imposed severe pressure just can finish, and operating efficiency is very low, and the quality of production be difficult to guarantee, and iron filings fall on operator's the body or in the eyes easily, causes unexpected the generation.

Summary of the invention

The utility model provides a kind of facing upward to bore auxiliary Electric drill support, operation effort when having solved the electric drill up-hole, and the phenomenon that personnel come to harm easily takes place.

Technical solution of the present utility model is as follows: constitute quadric chain by upper rack posts, elevating lever, connecting plate and handle bracket, wherein, the upper rack posts two ends are respectively equipped with bearing, elevating lever is inserted in the bearing, constitute relative reciprocating mechanism, the connecting plate two ends are hinged with upper rack posts and handle bracket respectively, and the top of handle bracket and elevating lever middle part are hinged, the handle bracket lower end is a joystick, downwards the application of force and the arm of force that extends; The bottom of upper rack posts is set with telescopic lower fulcrum bar, plays and supports and the height regulating action of whole frock, and base is located at the root of lower fulcrum bar, supports pole and the floor is shielded.The elevating lever top is provided with V shape electric drill jig, passes through two nut checks for pressing plate on it.

Good effect of the present utility model is: convert downward power to upwards electric drill pressure by quadric chain, and the effect with amplification power.Operating personnel have adjustable for height function away under the electric drill, are applicable to the operation of the various height of different automobile types.The electric drill stroke should possess controllable functions, prevents that electric drill from excessively rising, and damages all the other positions.The fixed form of electric drill on pole is simple and reliable, when electric drill pole below does not contact with the floor, has safeguard measure, prevents from the floor is extruded pit.Effectively raise operating efficiency, and when guaranteeing assembly quality, exempted the injury that a large amount of aluminium bits cause human body.

Description of drawings

Fig. 1 is the utility model structure principle chart.

The specific embodiment

According to shown in Figure 1, upper rack posts 4, elevating lever 6, connecting plate 8 and handle bracket 7 constitute quadric chain, wherein, upper rack posts 4 two ends are respectively equipped with bearing 5, and elevating lever 6 is inserted in the bearing 5, constitute relative reciprocating mechanism, connecting plate 8 two ends are hinged with upper rack posts 4 and handle bracket 7 by pin 11 respectively, the top of handle bracket 7 and elevating lever 6 middle parts are hinged by pin 13, and handle bracket 7 lower ends are joystick, downwards the application of force and the arm of force that extends; The bottom of upper rack posts 4 is set with telescopic lower fulcrum bar 3; play the height regulating action of support and whole frock; the bottom of lower fulcrum bar 3 is equipped with iron bearing 2 by pin 12, and the bottom of iron bearing 2 also is provided with timber saddle 1, supports pole and the floor is shielded.The top of elevating lever 6 is provided with V shape electric drill jig 9, is that pressing plate 10 is by 14 lockings of two nuts on it.

This frock range is 100mm, utilizes the characteristics at quadric chain dead point, can fully satisfy the actual needs of roof boring.Last lower fulcrum bar is made of square steel tube, and stiffness is good, and is in light weight, and has enough stiffness to guarantee operation.Base lower floor adopts wooden structures, can effectively protect the floor cloth surface.The upper strata is welded with steel plate, is guaranteeing that pole can help the rotary manipulation of all directions in car under the prerequisite of bearing 180 degree rotations.Because the operating space difference of different operations so need to measure earlier before use the height of operating space, is adjusted the height of pole again, the height of operating space should be that the pole maximum adds 50mm.This frock has designed two place's tunable arrangements, and promptly two support bars are scalable, only need to adjust alignment pin position just can, by adjusting the installing hole between elevating lever and connecting rod, also can reach the adjustment effect simultaneously.Need in the operating process electric drill is fixed on pole top, require the installation process simple and fast simultaneously, according to the curve of electric drill itself, make a jig that meets the electric drill outer shape, top compresses the top of electric drill with a pressing plate.

Claims

1. face upward the auxiliary Electric drill support of brill for one kind, it is characterized in that: constitute quadric chain by upper rack posts, elevating lever, connecting plate and handle bracket, wherein, the upper rack posts two ends are respectively equipped with bearing, and elevating lever is inserted in the bearing, constitute relative reciprocating mechanism, the connecting plate two ends are hinged with upper rack posts and handle bracket respectively, the top of handle bracket and elevating lever middle part are hinged, and the handle bracket lower end is a joystick, downwards the application of force and the arm of force that extends; The bottom of upper rack posts is set with telescopic lower fulcrum bar, plays the height regulating action of support and whole frock, and base is located at the root of lower fulcrum bar, and the top of elevating lever is provided with V shape electric drill jig, passes through two nut checks for pressing plate on it.
