Abstract
The utility model discloses a linkage compression-type multi-hole drilling tool which comprises a multi-spindle drill chuck, a moulding plate, guiding rods, a base, cushion blocks, a positioning mandrel, a pressure head, a drill bush, a small spindle, a spring and a nut, wherein a bottom plate and the guiding rods form a frame structure, the positioning mandrel and the cushion blocks are arranged in the middle of the moulding plate, the moulding plate is positioned below the multi-spindle drill chuck, with the molding plate and the multi-spindle drill chuck are arranged parallelly at intervals, and the spring is arranged between the moulding plate and the multi-spindle drill chuck which are connected through the small spindle and the nut to form a link mechanism capable of flexibly and axially moving along the guide rods. The pressure head on the bottom surface of the moulding plate is coaxially opposite to the positioning mandrel. During the use, the moulding plate moves together with the multi-spindle drill chuck up and down along the guide rods, when the pressure head is in contact with a workpiece, the moulding plate stops moving, the compressed spring compresses the workpiece in virtue of elastic force, and then the drill bit carries out drilling under the protection and the guidance of the drill bush. After the drilling, the multi-spindle drill chuck moves upward, the pressure head is divorced from the workpiece, the processed workpiece is taken out, and after repeated operations, batch production can be achieved. After the adoption of the utility model, auxiliary productivity labor hour is short, and the production efficiency is high.
Description
Technical field
The utility model relates to a kind of drilling processing apparatus that is used for machinery manufacturing industry, and specifically, the utility model relates to a kind of drilling tool that links with drilling that compresses under the workpiece location condition.
Background technology
Batch drilling adds man-hour, implements drilling processing by special-purpose positioning fixture and drill jig usually.Want earlier the dismounting of return preface after the workpiece completion of processing, and then workpiece to be processed is installed, so repeatable operation is the feature of prior art.Obviously, man-hour is longer than the drilling machining period in the prior art supplement production, thereby causes production efficiency low, does not meet the production in enormous quantities instructions for use.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of coordinated type compression type porous drilling tool, and this drilling tool template is moved with compressing with drill chuck, and its linkage structure is simple, and work-handling is easy, compresses reliably the drilling steady quality.
The utility model is achieved through the following technical solutions technical goal.
Interlock compression type porous drilling tool, it comprises multi-drill chuck, template, guide post, base, cushion block, positioning core axle, pressure head, drill bushing, little axle, spring and nut.Described base plate both sides are respectively equipped with the guide post of vertically-arranged, and the middle part is provided with positioning core axle up, and the positioning core axle both sides are provided with contour cushion block, and the axis of positioning core axle is vertical with the last plane of cushion block.Described template is positioned under the multi-drill chuck, both flat shapes and measure-alike and be parallel to each other, the bit location equivalent of corresponding multi-drill chuck configuration drill bushing on the template plate face.Its improvements are: on described multi-drill chuck and the template biside plate face opposite position, be provided with through hole with the guide post matched in clearance, be provided with spring between multi-drill chuck and the template, and connect into the link gear that can move along the guide post axial elasticity by little axle and nut.Middle part, described template bottom surface is provided with the pressure head of evagination down.
In the said structure, the spring that is positioned at both sides is made a concerted effort less than the centripetal force of multi-drill cover chuck, and the pressure head that is positioned at middle part, template bottom surface is coaxial with positioning core axle, positioning core axle and workpiece endoporus matched in clearance.
The utility model compared with prior art has following good effect.
1, template and multi-drill chuck elastic connection structure are simple, and it is effective to link, and neither want prior workpiece pressing, also do not dismantle compressing fixture afterwards, significantly reduce supplement production man-hour, have significantly improved production efficiency;
2, workpiece is compressed by the pressure head that arrives earlier under location condition, implements drilling processing by the drill bit of multi-drill chuck again, and the cutting crudy is good under stable condition.
Description of drawings
Fig. 1 is that the utility model is treated the workpiece location and installation or waited to get the structural representation of finished work.
Fig. 2 is that the utility model is implemented the structural representation that drilling adds man-hour behind workpiece pressing.
The specific embodiment
The utility model is described in further detail with reference to the accompanying drawings below.
Interlock compression type porous drilling tool shown in Figure 1 is to treat the workpiece location and installation or the structural representation when waiting to get finished work, and it comprises multi-drill chuck 1, template 2, guide post 3, base 4, cushion block 5, positioning core axle 6, pressure head 7, drill bushing 8, little axle 9, spring 10 and nut 11.Base plate 4 both sides that are positioned at the bottom are respectively equipped with the guide post 3 of vertically-arranged, and the middle part is provided with positioning core axle 6 up, and the external diameter of positioning core axle 6 equals hole dimension in the workpiece, both matched in clearance.Positioning core axle 6 both sides are provided with contour cushion block 5, and the axis of positioning core axle 6 is vertical with the last plane of cushion block 5.Superposed multi-drill chuck 1 is driven by drilling machine, is provided with template 2 under the multi-drill chuck 1, both flat shapes and measure-alike and be parallel to each other.The bit location equivalent of corresponding multi-drill chuck 1 is provided with drill bushing 8 on the template 2 plate faces, and present embodiment is provided with the drill bit of 4 equidistant same sizes.On multi-drill chuck 1 and the template 2 biside plate face opposite positions, be provided with through hole with guide post 3 matched in clearance, be provided with spring 10 between multi-drill chuck 1 and the template 2, but and by little axle 9 and nut 11 connect into elastic telescopic along guide post 3 axially movable link gears.Middle part, template 2 bottom surfaces is provided with the pressure head 7 of evagination down, and pressure head 7 is coaxial relative with positioning core axle 6.
The utility model adopts template 2 and multi-drill chuck 1 elastic connection structure, neither wants prior workpiece pressing, does not also dismantle compressing fixture afterwards, significantly reduces supplement production man-hour, has significantly improved production efficiency, and stable processing quality.
