Abstract
The invention discloses equipment for drilling central holes. The equipment comprises a baseframe, and the baseframe is slidably matched with a shaft bush which is horizontally placed in an inner hole of the baseframe, and is combined with a working spindle which passes through an inner cavity of the baseframe through a connecting piece. A transmission piece which is driven by a power source drives the working spindle to rotate, and the end part of the working spindle is provided with a blind hole (installation central drill) along the axial line of the working spindle. The periphery at the bottom of the shaft bush is radially provided with transmission teeth, and an operation rod of a gear mechanism which is engaged with the transmission teeth extends out of the baseframe. The baseframe is provided with a fixed clamping disc away from the power source, and the end part of the working spindle extends into a central hole of the clamping disc. The equipment has the advantages of simple and compact structure, small volume and flexible operation, and regardless of the thickness and length of workpieces, the equipment can conveniently drill the central holes at the end parts of the workpieces. The manufacturing cost of the equipment is low, so that the equipment is the optimal alternative equipment of a professional central drilling machine.
Description
Technical field
The present invention relates to a kind of machining equipment, especially relate to a kind of centering machine.
Background technology
At mechanical processing industry, centering is the work that often will carry out, because my company is the specialized factory that produces hydraulic support, in hydraulic support, machined piece accounts for about 50% of weight support frame, and some rod members in these machined piece such as the extension bar in the column, the piston rod in the jack, guide rod etc. all are to adopt the round steel blanking, centering then, it is rough turn to go up lathe again.When not having the equipment of special-purpose centering, generally be on drilling machine, to carry out this work, soon workpiece is holded up and is fixed, and centering is not only wasted time and energy then, also needs at least two people to cooperate and just can finish this operation.Long for workpiece length, owing to be subjected to the restriction of the drilling machine range of work, need dig a dell in that drilling machine is other, place into workpiece vertically the back centering, inefficiency, labor strength is big, has had a strong impact on manufacturing schedule during batch process.And special-purpose punch device complex structure not only also needs a large amount of fund inputs.
Summary of the invention
The object of the present invention is to provide that a kind of production cost is low, simple in structure, the centering machine of flexible and convenient operation.
For achieving the above object, the present invention can take following technical proposals:
Centering machine of the present invention, comprise support, the axle sleeve that lies in a horizontal plane in the described support endoporus to be slidingly matched combines with the working-spindle that passes from its inner chamber by connector, driving member by drive power source drives described working-spindle rotation, offers blind hole in the end of described working-spindle along its axis; Radially offer driving cog being positioned on the outer peripheral face of axle sleeve bottom, the control stick of the gear mechanism that is meshed with described driving cog extends outside the described support; Support away from power source is provided with fixedly chuck, and the end of described working-spindle extends in the centre bore of described chuck.
Described driving member is the outer cubic power transmission shaft that is connected with the power output shaft key, and the interior sides nut that is sleeved on the described outer cubic power transmission shaft is combined as a whole by attachment screw and described working-spindle.
Described connector is bearing and the clamping cap that is arranged between described axle sleeve two ends working-spindle and the axle sleeve.
The end of described control stick is provided with crank.
On described support, offer the oil filler point that is connected with described axle sleeve outer peripheral face.
When the invention has the advantages that work, the centre drill of in the blind hole of working-spindle end, packing into, move to the residing position of workpiece with balance crane this equipment that plays then, with fixing gripper chuck clamping of workpieces, start power supply, the rotation of driven by motor working-spindle, rotate control stick, the axle sleeve band that driving cog is meshed with gear mechanism working-spindle and is moved forward, and centre drill is at the surface of the work centering, then, the backward rotation control stick, working-spindle unclamps chuck along with axle sleeve together withdraws from backward, unload workpiece, finish the work of workpiece centering.During practical operation, motor does not cut out, but the continued operation centering.The present invention is simple in structure, compact, and volume is small and exquisite, flexible operation, and no matter workpiece thickness, length all can be very easily at its end centerings, and is cheap for manufacturing cost, is the best alternate device of professional centering machine.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in the figure, centering machine of the present invention, comprise support 1, the axle sleeve 2 that lies in a horizontal plane in described support 1 endoporus to be slidingly matched combines with the working-spindle 3 that passes from its inner chamber by connector, the driving member that is driven by power source 4 drives described working-spindle 3 rotations, offers blind hole 5 in the end of described working-spindle 3 along its axis; Radially offer driving cog 6 being positioned on the axle sleeve 2 bottom outer peripheral faces, the control stick 7 of the gear mechanism that is meshed with described driving cog 6 extends outside the described support 1; Support 1 away from power source 4 is provided with fixedly chuck 8, and the end of described working-spindle 3 extends in the centre bore of described chuck 8.Described driving member is the outer cubic power transmission shaft 10 that is connected with power output shaft 9 keys of power source 4, the interior sides nut 11 that is sleeved on the described outer cubic power transmission shaft 10 is combined as a whole by attachment screw 12 and described working-spindle 3, outer cubic power transmission shaft 10 rotates, and interior sides nut 11 drives working-spindle 3 and rotates together.Described connector is bearing 13 and the clamping cap 14 that is arranged between described axle sleeve 2 two ends working-spindles 3 and the axle sleeve 2, after clamping cap 14 compresses bearing 13, because working-spindle 3 is provided with step, so working-spindle 3 is also compacted, make axle sleeve 2 and working-spindle 3 form an integral body, can move forward and backward along with axle sleeve 2.The end of described control stick 7 is provided with crank 15, can control moving forward and backward of working-spindle 3 easily.Offer the oil filler point 16 that is connected with described axle sleeve 2 outer peripheral faces on described support 1, can inject lubricating oil at any time, retainer shaft is enclosed within the support smooth sliding all the time.
