The utility model is achieved in that
A kind of drilling machine, comprise work top, support, lowering or hoisting gear, main shaft and drive motors, described Bracket setting is on work top, described lowering or hoisting gear is arranged on support, main shaft and drive motors to be arranged on lowering or hoisting gear and to be in transmission connection, main shaft end is provided with drill bit, and described work top is square mesa, and work top is provided with Work fixing device;
Described Work fixing device comprises two screw rod fixed sleeve part, static V-type fixed block and activity V-type fixed block, described screw rod fixed sleeve part comprises screw rod and is provided with the holder of the screw suitable with described screw rod, described holder is relatively arranged on two long limits of work top, described screw rod is bolted in described screw, described activity V-type fixed block comprises described screw rod, holder and V-type fixed block, screw rod is bolted in the screw of holder, V-type fixed block is arranged at screw rod and points on the termination of work top, described static V-type fixed block and activity V-type fixed block are relatively arranged on two minor faces of work top.
Wherein, described screw rod refers to be provided with crank on the termination of work top.
Wherein, described activity V-type fixed block comprises two screw rods, described holder has been arranged side by side two screws, and described V-type fixed block is arranged on the termination of two screw rods.
Wherein, described holder and static V-type fixed block are secured by bolts on work top.
Wherein, the inner side of described V-type fixed block is provided with fixed groove.
Wherein, described drilling machine is numerical control drilling machine.
The utility model tool has the following advantages: the utility model drilling machine by arranging screw rod fixed sleeve part, static V-type fixed block and activity V-type fixed block on work top, for positioning workpiece to be processed, overcome the inconsistent and inaccurate problem in location that is that cause of workpiece blank appearance profile, improve Workpiece Machining Accuracy.
Accompanying drawing explanation
Fig. 1 is the work top of the utility model drilling machine and the structural representation of Work fixing device;
Fig. 2 is the schematic diagram after Fig. 1 installs workpiece.
Label declaration:
1, work top; 2, static V-type fixed block; 31, holder; 32, screw rod;
4, V-type fixed block.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1 and Fig. 2, a kind of drilling machine, comprise work top 1, support, lowering or hoisting gear, main shaft and drive motors, described Bracket setting is on work top, and described lowering or hoisting gear is arranged on support, main shaft and drive motors to be arranged on lowering or hoisting gear and to be in transmission connection, main shaft end is provided with drill bit, and wherein, described support, lowering or hoisting gear, main shaft and drive motors are all consistent with the 26S Proteasome Structure and Function on existing drilling machine, therefore, just no longer burdensome here.
It is the improvement of fixture on work top that the utility model drilling machine mainly improves, and described work top 1 is square mesa, and on work top, 1 is provided with Work fixing device;
Described Work fixing device comprises two screw rod fixed sleeve part, static V-type fixed block 2 and activity V-type fixed block, described screw rod fixed sleeve part comprises screw rod 32 and is provided with the holder 31 of the screw suitable with screw rod, described holder 31 is relatively arranged on two long limits of work top 1, described screw rod 32 is bolted in described screw, described activity V-type fixed block comprises described screw rod 32, holder 31 and V-type fixed block 4, screw rod 32 is bolted in the screw of holder 31, V-type fixed block 4 is arranged at screw rod and points on the termination of work top 1, described static V-type fixed block 2 and activity V-type fixed block are relatively arranged on two minor faces of work top 1, wherein, described holder 31 and static V-type fixed block 2 are secured by bolts on work top 1, certainly, described holder and static V-type fixed block also can be fixed on work top by other modes such as welding.
Therefore, workpiece can be fixed on workpiece table top by tie down screw, and, described static V-type fixed block and activity V-type fixed block can realize workpiece is located automatically, therefore, no longer need to find datum mark at the blank profile of workpiece and realize location, not only self-locating function can be realized by screw rod fixed sleeve part, static V-type fixed block and activity V-type fixed block, also substantially increase the intensity that workpiece is fixing, overcome in Workpiece boring process and by the problem of brute force movement, machining accuracy may be further increased.
