Abstract
The utility model discloses a magnetic drill arm which relates to the technical field of special automobile manufacturing. The magnetic drill arm comprises a magnetic drill, a stand column which is arranged on the ground, and a short arm which is hinged at the top of the stand column, wherein the short arm is hinged with a long arm; a balancer which is internally provided with a steel wire rope is arranged on the long arm; the steel wire rope of the balancer is wound through a fixed pulley at the front end of the long arm to be connected with the magnetic drill. Compared with the prior art, the magnetic drill arm is capable of solving the problems of large potential safety hazard and low working efficiency caused by carrying out mounting hole drilling on the carriages and chassis of dumpers by using the existing magnetic drills.
Description
Technical field
The utility model relates to speciality car manufacturing technology field, especially a kind of for the magnetic drill arm on body of tipper carriage manufacturing line.
Background technology
The assembling on body of tipper carriage and chassis is that the supporting base of chassis rear end, saddle clip and chassis ridgepole cant board are connected with the underframe longeron in compartment by bolt; Conventionally the mounting hole of, assembling use for both is to join and come outbreak out at both connecting portions after compartment is placed on to chassis; Due to the existing job operation of mounting hole be with manpower by magnetic drill end to chassis ridgepole cant board position, magnetic drill is adsorbed on riser, mounting hole is got out.There are the following problems in process of production for this job operation: 1, because magnetic drill relies on magnetic-adsorption on riser, magnetic drill is adsorbed on the height of nearly one meter far from ground of the position of riser, in boring procedure, excessive or the unexpected power-off of drill thrust all can cause magnetic drill to drop, and has potential safety hazard; 2, bored a hole and changed to and bore when another hole, need magnetic drill displacement with manpower end, people is easily tired, the large and inefficiency of labour intensity.
Utility model content
The purpose of this utility model is to provide a kind of magnetic drill arm, and this magnetic drill arm can solve existing use magnetic drill to carry out mounting hole to body of tipper carriage and chassis and join large, the ineffective problem of potential safety hazard of boring.
In order to address the above problem, the technical solution adopted in the utility model is: this magnetic drill arm includes magnetic drill, there is a drop shot arm that is arranged on ground column and is hinged on described column top, described drop shot arm is hinged with long arm, the balancing device of steel rope is housed in being provided with on described long arm, and the steel rope of described balancing device is walked around the fixed pulley that is located at described long arm front end and is connected with described magnetic drill.
In technique scheme, technical scheme can also be more specifically: described column is hinged by jointed shaft and described drop shot arm; Described drop shot arm is hinged by bearing pin and described long arm.
Further, the bottom of described column is provided with connecting panel, and described connecting panel fixes on the ground by expansion bolt.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect: 1, in fitting process, lift without manpower end, just can use easily magnetic drill to hole to the large beam sides of self-dumping undercarriage for automobile, alleviate the working strength of manpower, reduce potential safety hazard, and improved work efficiency; 2, because column is connected with bearing pin with drop shot arm, drop shot arm is connected with bearing pin with long arm, and two arms all can freely swing and stretch, can realize magnetic drill to chassis ridgepole cant board far, the closely processing in hole.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Magnetic drill arm includes magnetic drill 7 as depicted in figs. 1 and 2, has one to be arranged on ground column, has connecting panel 1 at the bottom welding of column 2, and connecting panel 1 fixes on the ground by the expansion bolt installing thereon; Have hinged block in column 2 welded top, column 2 is hinged with one end of drop shot arm 3 by being contained in jointed shaft on hinged block 8; The other end of drop shot arm 3 is hinged by the long arm 4 of bearing pin 9, at the front end of arm 4, fixed pulley 6 is housed; The balancing device 5 of steel rope 10 in being provided with, a side of long arm 4 is housed, the steel rope 10 of balancing device 5 is walked around the fixed pulley 6 that is contained in long arm 4 front ends and is connected with magnetic drill 7, magnetic drill 7 is positioned at the below of fixed pulley 6, and magnetic drill 7 can be under the effect of balancing device 5, upper and lower motion; The present embodiment is freely swung and is stretched by drop shot arm 3 and long arm, and the upper and lower motion of magnetic drill 7, can realize to self-dumping undercarriage for automobile crossbeam cant board far, the closely processing in hole and hole, upper and lower position.
