The specific embodiment
By describing technology contents of the present invention, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 3 and Fig. 4, the invention provides a kind of angle adjustable drilling machine, it mainly includes pedestal 10, drilling equipment 20 and angle regulator.Wherein, pedestal 10 is provided with the processing platform 11 for placing part to be processed, and processing platform 11 tops arrange described drilling equipment.Different from traditional drilling machine, in this patent, drilling equipment 20 is arranged on angle regulator, concrete, and angle regulator comprises axle 31 and regulates screw mandrel 32.Wherein, the setting of axle 31 should be relative fixing with processing platform, the most exactly axle 31 is arranged on pedestal 10, the effect of axle 31 is that drilling equipment 20 is articulated on pedestal 10, and then drilling equipment 20 just can rotate with respect to processing platform 11 along this axle 31, thereby realize the demand that turns to different angles.The rotation of drilling equipment 20 is by regulating screw mandrel to realize, concrete, the inclined to one side upper position of drilling equipment is hinged with joint sleeve, on joint sleeve, be provided with internal thread, the external screw thread of ball screw and internal thread are mutually adaptive, therefore, and in the time of rotation ball screw mandrel, the connecting duct that is positioned at both sides will be shunk or be stretched out uniformly, drives whole drilling equipment to rotate on axle 31 simultaneously.
Further, in order to limit and to make the rotation of drilling equipment 20 controlled, need to use governor motion, its concrete structure scheme can adopt the common position limiting structure of multiple mechanical field, for example between drilling equipment 20 and axle 31, Jing Zhao mechanism is set, adopt latch engagement to fix etc., as long as such scheme can play the rotation capable of regulating at axle 31 to drilling equipment 20, and can fix after adjusting to certain set angle of inclination, in one embodiment, in described frame take axle as the center of circle, be provided with deep-slotted chip breaker, and on drilling equipment, be provided with the fixing hole of set bolt, when drilling equipment turns to ad-hoc location, just can pass drilling equipment and pass the deep-slotted chip breaker in frame by bolt, and be fixed with nut.
Thus, compare the nonadjustable drilling machine of direction in the past, technical solution of the present invention is owing to having introduced angle regulator on drilling machine, thereby make drill bit can adjust to easily different required angles on horizontal plane, carry out drilling operation, the production in enormous quantities to beating inclined-hole part is achieved.
The present embodiment is that provide based on such scheme a kind of is used for processing the angle adjustable drilling machine of brake block steel liner plate 90 as shown in Figure 1, 2 specially.As seen from the figure, the arcuate flanks 91 of brake block steel liner plate 90 each side needs to make a call to a hole 92, therefore in order at utmost to improve the production efficiency to this kind of product, in the present embodiment, be that a corner of table degree adjustable drilling machine is equipped with two drilling equipments simultaneously, corresponding, the axle 31 of its angle regulator also includes two, in order to ensure the synchronous adjustment of two drilling equipments, two axles 31 also should level intervals and are all relatively-stationary setting with processing platform, and then, on each axle 31, be socketed respectively one of them drilling equipment 20.Further, in the present embodiment, the core component of governor motion adopts and regulates screw mandrel 32, in order to realize spacing, the adjustment to two drilling equipments 20, the be spirally connected two ends of described adjusting screw mandrel 32 of the middle part end on the upper side that the middle part end on the lower side of each drilling equipment 20 is socketed 31, two drilling equipments 20 of axle of described angle regulator.
Thus, when the different brake block steel liner plates 90 of processing, by rotation, regulate two drilling equipments 20 of adjustment that screw mandrel 32 can link simultaneously to make it around axle 31, rotate the object that plays adjusting angle, after putting in place, adjusting regulate screw mandrel 32 spiro connection structures own can effectively guarantee the position-limiting action to two drilling equipments 20, again brake block steel liner plate 90 is placed on processing platform 11 and can disposable be holed in brake block steel liner plate 90 both sides simultaneously, greatly improved the production efficiency of product.
As an embodiment, above-mentioned drilling equipment 20 specifically includes pedestal, feed mechanism 21, drill bit 22; And rotating mechanism 23.Wherein, pedestal be socked shaft 31 and with the critical piece that is connected governor motion, it provides a basic platform for whole drilling equipment 20.And feed mechanism 21 further comprises fixed part and moving part, fixed part is arranged on pedestal, and described drill bit 22 is set on moving part, described transmission mechanism 23 and its rotation of drill bit 22 linkage driving.Thus, drilling equipment 20 entirety can be adjusted angle around axle 31 rotations, after angle puts in place, by position limiting structure, limit the position of drilling equipment, be specially the fixing of fixed part, during work, the moving part of himself feed mechanism 21 moves, by the movement of moving part, adjust the distance between drill bit and processing platform, make this drilling machine can realize the steel plate processing of different-thickness, drill bit 22 rotation under rotating mechanism 23 interlocks, feeding can complete drilling operation.
As an embodiment, angle adjustable drilling machine also comprise electric control gear 50 and control foot-operated 40, the rotating mechanism 23 that described electric control gear 50 is electrically connected described drilling equipment 20 with control foot-operated 40.Controlling foot-operated 40 can, according to the bottom that is arranged on pedestal 10 easy to use, can arrange as required on electric control gear 50, once control foot-operated 40 is operated or discharges, drives the rotating mechanism 23 of drilling equipment 20 to drive drill bit 22 to work.Design thus and switch is moved on to operator's pin control, can discharge its both hands, accelerate the working (machining) efficiency of workpiece.
As an embodiment, the feed mechanism 21 of above-mentioned drilling equipment 20 is straight line cylinder or linear electric motors, and described straight line cylinder or linear electric motors are electrically connected with electric control gear 50.The present embodiment provides a scheme that drilling equipment 20 is automatically controlled, by adopting straight line cylinder or linear electric motors, thereby when electric control gear 50 sends work order, the moving part of straight line cylinder or linear electric motors moves, and then drive drill bit 22 to complete feeding operation.Certainly, in order to save cost, the feed mechanism 21 of drilling equipment 20 also can adopt the pure frame for movement adopting on tradition as existing a lot of vertical drilling machines to realize.
As an embodiment, above-mentioned rotating mechanism 23 comprises motor, driving belt and belt pulley, and described drill bit 22 is socketed belt pulley, and described driving belt is socketed on respectively on motor and belt pulley; Described motor is electrically connected with electric control gear.Except aforesaid way, rotating mechanism 23 also can adopt motor straight to connect in succession drill bit 22, or motor connects the schemes such as drill bit 22 by gear-box etc.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
