Abstract
The utility model discloses a drilling machine for machining a center hole in a large shaft. The drilling machine comprises a concave base, a machine base connected with the lateral end of the concave base and two V-shaped support devices arranged in a groove in the concave base. A case is arranged on the lateral portion at the top end of a machine seat, and a center drill and a motor are installed on two sides of the machine base on the case. Each V-shaped support device comprises a cylinder, a V-shaped support seat and an adjusting mechanism connecting the cylinder and the V-shaped support seat, a wheel is installed at the bottom of the cylinder, and the diameter of the cylinder is matched with the width of the groove in the concave base. A central line of the center drill in the horizontal level and a central line of the V-shaped support seats in the horizontal level coincide. The drilling machine is simple in structure, low in construction cost, convenient to operate and capable of being located accurately. Self gravity of the large shaft is utilized to support and fix the large shaft to conduct machining.
Description
Technical field
The utility model relates to a kind of drilling machine, particularly a kind of drilling machine of processing main shaft central hole.
Background technology
General shaft-like workpiece all can bore a centre bore man-hour adding, be all generally to get out on centre-drilling lathe, Main Function is supporting and location, prevents workpiece work in-process beat, increase workpiece and adding the rigidity in man-hour, but there is complex structure and the high shortcoming of cost in existing centre-drilling lathe.Large shaft-like workpiece has that volume is large, the quality feature such as heavily, but there be limited evidence currently of has the device that utilizes the special processing main shaft central hole that this own characteristic of macro-axis class workpiece designs.
Utility model content
The utility model is for the technical problem existing in prior art, and object is to provide a kind of drilling machine of special processing main shaft central hole, and that this drilling machine has advantages of is simple in structure, cost is low and accurate positioning.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of drilling machine of processing main shaft central hole, comprise spill base, the support that spill base side connects and be placed on two V-arrangement bracing or strutting arrangements in spill base further groove, the sidepiece on support top is provided with cabinet, on cabinet, in the both sides of support, be separately installed with centre drill and motor, V-arrangement bracing or strutting arrangement comprises cylinder, the governor motion of V-arrangement supporting seat and connecting cylinder and V-arrangement supporting seat, cylindrical base is provided with scroll wheel, the recess width of the diameter of cylinder and spill base adapts, center line in center line in centre drill horizontal direction and V-arrangement supporting seat horizontal direction coincides.
Preferably, governor motion comprises lifting screw and the hand wheel nut being threaded with lifting screw, and the upper end of cylinder is shaped with the inner bolt hole adapting with lifting screw.
Preferably, support is arranged to triangle.
Adopt the beneficial effect of technique scheme to be: the utility model is simple in structure, cost is low, easy to operate, by the diameter of cylinder being set and the recess width of spill base adapts, can make V-arrangement bracing or strutting arrangement sliding process in the groove of spill base not be offset, to guarantee that the center line in centre drill horizontal direction keeps overlapping with the center line in V-arrangement supporting seat horizontal direction, the height of adjusting macro-axis class workpiece centre by the governor motion on V-arrangement bracing or strutting arrangement is again to adapt to the height of centre drill, can accurately locate, then utilizing the gravity of macro-axis self to support fixedly macro-axis processes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model and structure are described, so that those skilled in the art understand.
As shown in Figure 1, a kind of drilling machine of processing main shaft central hole, comprise spill base 1, the support 2 that spill base 1 side connects and be placed on two V-arrangement bracing or strutting arrangements 3 in spill base 1 further groove, the sidepiece on support 2 tops is provided with cabinet 4, on cabinet 4, in the both sides of support 2, be separately installed with centre drill 5 and motor 6, V-arrangement bracing or strutting arrangement 3 comprises cylinder 7, the governor motion of V-arrangement supporting seat 8 and connecting cylinder 7 and V-arrangement supporting seat 8, cylinder 7 bottoms are provided with scroll wheel, the recess width of the diameter of cylinder 7 and spill base 1 adapts, center line in center line in centre drill 5 horizontal directions and V-arrangement supporting seat 8 horizontal directions coincides.Governor motion comprises lifting screw 10 and the hand wheel nut 9 being threaded with lifting screw 10, and the upper end of cylinder 7 is shaped with the inner bolt hole adapting with lifting screw 10.Support 2 is arranged to triangle.
The utility model is simple in structure, cost is low, easy to operate, by the diameter of cylinder being set and the recess width of spill base adapts, can make V-arrangement bracing or strutting arrangement sliding process in the groove of spill base not be offset, to guarantee that the center line in centre drill horizontal direction keeps overlapping with the center line in V-arrangement supporting seat horizontal direction, the height of adjusting macro-axis class workpiece centre by the governor motion on V-arrangement bracing or strutting arrangement is again to adapt to the height of centre drill, can accurately locate, then utilize the gravity of macro-axis self to support fixedly macro-axis and process
Above-mentionedly by reference to the accompanying drawings utility model is exemplarily described; obviously the utility model specific implementation is not subject to the restrictions described above; as long as this non-essential improvement that has adopted method design of the present utility model and technical scheme to carry out; or without improving, the design of utility model and technical scheme are directly applied to other occasions, all within protection domain of the present utility model.
