Abstract
The utility model discloses a single-jaw heavy duty type caliper used for measuring the pitch of V-CUT grooves on printed boards, which comprises a main ruler and an auxiliary ruler. The caliper is characterized by also comprising two measurement jaws. The auxiliary ruler arranged on the main ruler can move back and forth along the main ruler. The front end of the main ruler is downwards extended with one measurement jaw, and the front end of the auxiliary ruler is downwards extended with the other measurement jaw. The bottom ends of the two measurement jaws are ground to be an inclined surface respectively. The inclined surfaces of the two measurement jaws are respectively attached to inclined surfaces on the two sides of V-CUT grooves and can also be in contact with the bottom surfaces of the V-CUT grooves. According to the technical scheme of the utility model, the single-jaw heavy duty type caliper solves the problem in the prior art that the measurement of the pitch of V-CUT grooves on two printed boards is troublesome in operation due to the reason that the center distance between grooves cannot be measured by means of a conventional three-purpose caliper due to the overlarge angle of the conventional three-purpose caliper. Meanwhile, the single-jaw heavy duty type caliper also solves the problem that when ground at a corresponding angle, the measuring part of the conventional three-purpose caliper is formed as a thin needle and is easily touched broken to be damaged. The single-jaw heavy duty type caliper is simple in structure and not easily damaged and can be used for quickly and accurately measuring the pitch of V-CUT grooves on printed boards.
Description
Technical field
The utility model relates to the heavy slide calliper rule of a kind of monodactyle, particularly relates to a kind of heavy slide calliper rule of monodactyle that are applicable to measure printed board V-CUT separation.
Background technology
In the PCB Production process, especially in the production scene, how adopting short-cut method accurately to record distance between two printed board V-CUT grooves, control well the crudy of this operation, is the problem of a headache.Common three-purpose calliper causes measuring very trouble because angle can't measure the centre distance of groove too greatly.If the measuring point is ground to corresponding angle, due to the structure of slide calliper rule, its measuring point just becomes a fine pin, is easy to touch disconnected, causes the damage of slide calliper rule, brings larger loss to enterprise.
The utility model content
In order to solve the distance of measuring in prior art between two printed board V-CUT grooves, common three-purpose calliper causes measuring very trouble because angle can't measure the centre distance of groove too greatly.If simultaneously the kind of calliper position is ground to corresponding angle, the measuring point just becomes a fine pin, be easy to touch disconnected, the problem that causes slide calliper rule to damage, it is a kind of simple in structure that the utility model provides, easy to use, can quick and precisely measure printed board V-CUT separation, and the heavy slide calliper rule of non-damageable monodactyle.
In order to address the above problem, technical solution adopted in the utility model is:
A kind of heavy slide calliper rule of monodactyle that are applicable to measure printed board V-CUT separation, comprise main scale and secondary chi, it is characterized in that: also comprise two measuring claws, secondary chi is arranged on main scale, and secondary chi can move forward and backward along main scale, extends a measuring claw downwards at the front end of main scale, extend a measuring claw downwards at secondary chi front end, the inclined-plane is worn in described two measuring claw bottoms, and the inclined-plane of described two measuring claws fits with the inclined-plane of the both sides of V-CUT groove respectively, and can contact with the V-CUT groove bottom.
Aforesaid a kind of heavy slide calliper rule of monodactyle that are applicable to measure printed board V-CUT separation, it is characterized in that: the angle of inclination, inclined-plane of described two measuring claws is identical.
Aforesaid a kind of heavy slide calliper rule of monodactyle that are applicable to measure printed board V-CUT separation, it is characterized in that: described measuring claw adopts No. 68 steel to make.
Aforesaid a kind of heavy slide calliper rule of monodactyle that are applicable to measure printed board V-CUT separation, it is characterized in that: the heavy slide calliper rule of described monodactyle adopt the heavy slide calliper rule of cursor type monodactyle or the heavy slide calliper rule of digital display type monodactyle.
The utility model beneficial effect is: the heavy kind of calliper pawl of the utility model monodactyle size approximately has the 4mm left and right, and its material is No. 68 steel, and the rigidity of whole measuring claw and toughness are all more moderate.The inclined-plane is worn in the measuring claw bottom, and the inclined-plane is the half-angle corresponding with the V-CUT angle of the v-groove, and its measurement face is straight line, and is good with contacting of flute bottom, can measure fast and accurately the distance between the V-CUT groove, uses very convenient.Because measuring claw has rigidity and toughness preferably, so measuring claw is not easy to damage, serviceable life is longer simultaneously.
Description of drawings
Fig. 1 is the heavy structure of calipers schematic diagram of monodactyle that the utility model is applicable to measure printed board V-CUT separation.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of heavy slide calliper rule of monodactyle that are applicable to measure printed board V-CUT separation, comprise main scale 1, secondary chi 2 and two measuring claws 3, secondary chi 2 is arranged on main scale 1, and secondary chi 2 can move forward and backward along main scale 1, front end at main scale 1 extends a measuring claw 3 downwards, extend a measuring claw 3 downwards at secondary chi 2 front ends, inclined-plane 4 is worn in described two measuring claw 3 bottoms, the inclined-plane 4 of described two measuring claws 3 fits with the inclined-plane of the both sides of V-CUT groove respectively, and can contact with the V-CUT groove bottom.
4 angles of inclination, inclined-plane of described two measuring claws 3 are identical.Described measuring claw 3 adopts No. 68 steel to make. and the heavy slide calliper rule of described monodactyle can adopt the heavy slide calliper rule of cursor type monodactyle or the heavy slide calliper rule of digital display type monodactyle.
In sum, the heavy kind of calliper pawl of the utility model monodactyle size approximately has the 4mm left and right, and its material is No. 68 steel, and the rigidity of whole measuring claw 3 and toughness are all more moderate.Inclined-plane 4 is worn in measuring claw 3 bottoms, and inclined-plane 4 is the half-angle corresponding with the V-CUT angle of the v-groove, and its measurement face is straight line, and is good with contacting of flute bottom, can measure fast and accurately the distance between the V-CUT groove, uses very convenient.Because measuring claw 3 has rigidity and toughness preferably, so measuring claw 3 is not easy to damage, serviceable life is longer simultaneously.
Above demonstration and described ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
