Abstract
The utility model relates to a PCB (Printed Circuit Board) micro drill bit slotting clamp, which consists of a stable sleeve, a mandrel and a connecting rod, wherein the mandrel is connected with the stable sleeve through a bearing in a penetrating manner; a through hole is arranged in the center of the mandrel; the connecting rod penetrates through and is arranged in the through hole of the mandrel; a drill bit chuck for clamping the drill bit is arranged at one end of the connecting rod; a clamping head connected with the main shaft of a slotting machine is arranged at the other end of the connecting rod; and a compression spring is arranged on the connecting rod. By using the clamp, the radial run-out of the drill bit for slotting due to the pressure of a slotting cutter can be overcome; the run-out of the drill bit in the rotating process can be ensured within 2 mum; and in addition, the drill bit is convenient to clamp, so that the slotting quality and the production efficiency of the drill bit are greatly improved.
Description
Technical field
The utility model belongs to microbit processing appurtenance technical field, particularly a kind of fluting anchor clamps that are used for the drill bit clamping.
Background technology
In known PCB microbit fluting clamping fixture, usually use baroque machine driving to realize the clamping of drill bit, and the rigidity of retained part is relatively poor, in the process of cutting fluting, after being subjected to the radial pressure of grooving tool, drill bit produces bigger beating, and the product fraction defective is higher, causes increasing of material resources and artificial waste and production cost.
The utility model content
The purpose of this utility model provides and a kind ofly can keep the stable of clamping drilling bit in rotation, improves crudy, reduces the PCB microbit fluting anchor clamps of defective products rate.
Realize that the technical scheme that the purpose of this utility model is taked is: PCB microbit fluting anchor clamps are formed by stablizing cover, axle and connecting rod, wherein, axle covers load and connects with stable by bearing, the centre of axle is provided with through hole, connecting rod is installed in the through hole of axle, one end of connecting rod is provided with the drill bushing that is used for clamping drilling bit, and the other end is provided with the clamping head that is connected with the groover main shaft, and connecting rod is provided with the compression spring.
The outer circumference portion bit strip of described axle one end has the retaining edge, and the through hole port in its centre is provided with the taper hole that cooperates with drill bushing.
Described bearing adopts pressure bearing.
The PCB microbit fluting clamping fixture of making according to such scheme, effect by stable cover and axle, the pressure that can overcome grooving tool causes the circular runout for the treatment of slotting drill bit, guarantee drill bit beating within 2um in rotary course reliably, and the clamping of drill bit is easy to operate, thereby the quality and the production efficiency of drill bit fluting are improved greatly.These anchor clamps can guarantee that drill bit realizes stepping up of drill bit and unclamp under the prerequisite of stable rotation, to satisfy the product required precision, have simple in structure, advantage such as serviceability is reliable, and is easy to operate.
Figure of description
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, PCB microbit of the present utility model fluting anchor clamps have a stable cover 7, and this stable cover 7 is coated with axle 5 by bearing 6, and described bearing 6 can adopt pressure bearing, to reduce the circular runout of axle 5 in stable cover 7.The centre of axle 5 is provided with through hole, and the front end of through hole is provided with the taper hole that cooperates with drill bushing 3, treats the clamping of slotting drill bit and to loosen realizing.Be coated with connecting rod 2 in through hole, an end of connecting rod 2 is provided with the tubaeform drill bushing 3 that is used for clamping drilling bit, and the other end is provided with clamping 4, is used for being connected with the clamping of drill bit groover main shaft.On connecting rod 2, be coated with compression spring 1, be used to control the clamping of drill bit and unclamp.Outer circumference portion bit strip at axle 5 one ends has the retaining edge, and the end face of retaining edge contacts with the end face of an end bearing.
Operation principle: these anchor clamps can 7 be fixed on the locating support of drill bit groover stablizing cover in use, and guarantee the axiality of itself and drill bit groover main shaft, the clamping of connecting rod 24 are connected with the main shaft clamping of drill bit groover again.Carry out drill bit fluting and add man-hour, hand-held clamping 4 presses down connecting rod 2, and the drill bushing 3 of connecting rod 2 moves down and break away from the taper hole of axle, and this moment, drill bushing 3 just unclamped automatically, can will treat that slotting drill bit inserts in the drill bushing 3; Then, unclamp clamping 4, by the effect of compression spring 1, connecting rod 2 is moved on automatically, drill bushing 3 enters the taper hole of axle 5, will treat that just slotting drill bit clamps, and clamping simultaneously 4 is connected with the main shaft clamping of drill bit groover, and rotates with main shaft.Repeat above-mentioned action, can finish the clamping that slotting drill bit was got and treated to unloading of slotting drill bit.These anchor clamps are by the effect of stable cover 7 and axle 5, and the pressure that can overcome grooving tool fully causes the circular runout for the treatment of slotting drill bit, guarantees drill bit beating within 2um in rotary course reliably.Simultaneously, connecting rod 2 is in move left and right manually and under the effect of spring 1, realizes stepping up and unclamping of chuck, with assurance drill bit stepping up and the unclamping after finishing of slotting in grooving process.
