Description

Workpiece drilling clamp
Technical field
The locating apparatus that the utility model uses when belonging to Workpiece boring, the workpiece being particularly thin axle to two ends clamps and the composite fixture positioned drilling tool.
Background technology
When specific workpiece being holed in workpiece industry, first need use the three-jaw chuck (calvus of three circumference distributions, by the centre place, one end of workpiece, three calvus extrude thus clamping position workpiece to center) clamping position is carried out to workpiece, then on fixing workpiece, determine bore position, then cutter is adjusted to respective bore position and carry out perforating, boring.
In boring procedure, produce radial (radial direction of finger-hole) to prevent cutter to jump, affect machining accuracy and drilling effect, one fuel plate bushing plate (being located by corresponding locating support) is set between cutter and workpiece, bushing plate offers the boring corresponding with bore position, the drill bushing of just allowing that cutter passes through is installed in boring.Cutter just need can touch workpiece by the bullport (gap value of cutter and bullport controls between 0.001 ~ 0.045mm) in this drill bushing.Such bushing plate and drill bushing just form the radial constraint to cutter, make cutter not easily sideslip, ensure that precision and the drilling effect of processing.
Along with the development of industrial society, there is increasing special-shaped workpiece, comprising the shaft member that a kind of two ends diameter partially thin (diameter is between 1 ~ 3cm) middle part is expanded.As shown in Figure 1, three calvus 1 front ends of three-jaw chuck are flat, in any case gather, always a leg-of-mutton gap 2 is there is between three calvus 1 and center, according to current size design, this gap generally can be greater than 5cm, so depend merely on existing three-jaw chuck cannot fix this type of shaft member.
If the fixing operation of workpiece is not properly settled, even if install the restriction bushing plate that jumps of cutter radial and drill bushing, the Drilling operation of this kind of shaft member also due to the location unstability of workpiece itself, and can cannot complete bore operation.
Utility model content
The technical problems to be solved in the utility model is difficult to for the shaft-like workpiece of thin narrow end the technological deficiency that grips, provides and such shaft member can be made to fix, the Workpiece drilling clamp of match-drill operation.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
Workpiece drilling clamp, comprise the locating support of clamping positioning mechainsm, bushing plate and bushing plate, bushing plate is located at top in the middle part of workpiece, and clamping positioning mechainsm is located at workpiece both ends respectively, the locating support of bushing plate comprises the fixing vertical rod supporting bushing plate, and bushing plate peripheral position is located in fixing vertical rod; Described clamping positioning mechainsm comprises lower bottom base and upperpush rod, and lower bottom base top offers for settling workpiece end V-arrangement opening, and opening forward upward; Fixing vertical rod upwards passes bushing plate, and upperpush rod is positioned at fixing vertical rod upper end by coupling assembling; Upperpush rod is the screw rod vertically arranged, and upperpush rod upper end is provided with lock-nut, through coupling assembling in the middle part of upperpush rod, lower end to stretch in V-arrangement opening and lower end diameter between 0.2 ~ 0.8cm, upperpush rod central shaft crosses the bottom of V-arrangement opening.
Adopt the utility model Workpiece drilling clamp, there is following technique effect:
First put into below bushing plate by workpiece, workpiece two ends are placed in V-arrangement opening part, due to V-arrangement opening forward upward, workpiece end directly has and how littlely all to drop on directly over V-arrangement open bottom like this, instead of drops on a certain sidewall completely; Because upperpush rod central shaft crosses the bottom of V-arrangement opening, such upperpush rod lower end will face workpiece end, as long as adjusting bolt, by upperpush rod toward lowering, upperpush rod lower end can compress workpiece also until push against.In V-arrangement opening and lower end diameter between 0.2 ~ 0.8cm, even if the diameter of workpiece end only has 1cm like this, upperpush rod also can compress workpiece, and can not form a closed leg-of-mutton clearance space.
Upperpush rod is positioned at fixing vertical rod upper end by coupling assembling, and fixing vertical rod is arranged on bushing plate peripheral position, these positions are selected to be all to avoid the primary artifact region of holing, i.e. upper area in the middle part of bushing plate, the operation that pushes against that so just can reach workpiece end does not affect but the object of match-drill operation.Upperpush rod is the screw rod vertically arranged, and upperpush rod upper end is provided with lock-nut, is conveniently to carry out descending operation and locking location to upperpush rod.
Further, the back shaft being located at below in the middle part of workpiece is also comprised.
If workpiece is long, for avoiding in process, workpiece generation deflection deformation, can arrange back shaft as support.
Further, also comprise base plate, the locating support of clamping positioning mechainsm and bushing plate is all located on base plate, is provided with Compress Spring between bushing plate and base plate, and this Compress Spring is set in fixing vertical rod; The upper end of fixing vertical rod is equipped with turning cylinder, this turning cylinder is installed with the cam be resisted against on bushing plate, turning cylinder is also provided with one handle.
Owing to needing to regulate the spacing between bushing plate and workpiece in boring procedure, rotate so arrange handle drives turning cylinder herein, the major axis of cam or minor axis is made to be resisted against bushing plate, under the effect of Compress Spring, bushing plate can decline or lifting adaptively, thus realizes bushing plate seat lifting adjusting easily.
Further, described locating support comprises four fixing vertical rods, and fixing vertical rod is evenly distributed in bushing plate both sides; Its quantity of described turning cylinder is at least two, between two the fixing vertical rods being located at homonymy respectively.
If only there is side to be provided with the above-mentioned turning cylinder with handle and cam, that bushing plate unbalance stress, easy generation is turned over partially, so at least need two turning cylinders being located at bushing plate respectively.
Further, described coupling assembling is fixed in fixing vertical rod or is set in the axle head of turning cylinder by matched in clearance.
Be fixed in fixing vertical rod and can realize the location of upperpush rod relative to fixing vertical rod; Hitch (owing to being matched in clearance, can not rotate thereupon) at the axle head of turning cylinder, turning cylinder is located in again the upper end of fixing vertical rod, also the location of upperpush rod relative to fixing vertical rod can be realized, but recently see with regard to distance, if the distance that axle moving axis passes fixing vertical rod is longer, the latter can be an optimum choice.
Further, described V-arrangement opening inner surface is evenly equipped with projection.
The setting of projection, makes to have different contact sites between workpiece end from V-arrangement opening, makes workpiece end be not easy to rotate, is conducive to clamping.
