Description
Technical field
The utility model relates to measuring slide calliper rule technical field, especially relates to a kind of lengthening formula slide calliper rule.
Background technology
Vernier caliper is a kind of measurer of measuring length, interior external diameter, the degree of depth.Vernier caliper is by main scale and be attached to that slidable vernier two parts constitute on the main scale.Two secondary movable measuring jaws are arranged on the main scale of vernier caliper and the vernier, are respectively interior measuring claw and external pelivimetry pawl, and interior measuring claw is commonly used to measure internal diameter, and the external pelivimetry pawl is commonly used to measure length and external diameter.
The vernier caliper of introducing above is a kind of general measurer, thinner owing to dividing the work in modern production, measure internal diameter or interior groove width at following needs of some operation, and need the part shape of measurement internal diameter or interior groove width different, for example internal diameter or inside groove are deep, need the position of measurement also deep, cause this general vernier caliper lack scope for their abilities, so just need special internal caliber gauge in the case.
As shown in Figure 1, be exactly existing a kind of internal caliber gauge, comprise rule (1), slide block (2), mobile jib (11), secondary bar (21), measuring head.As can be seen from the figure mobile jib (11) and secondary bar (21) are all long, as long as the degree of depth of measuring position just can be measured in the long scope of bar.But this shows that grown if the degree of depth of measuring position exceeds bar, this internal caliber gauge just can't have been measured.
In addition, measuring head among Fig. 1 and mobile jib (11) and secondary bar (21) are respectively integral type, when having worn and torn appears in the head of measuring head, the measuring accuracy of this internal caliber gauge will be affected, and can't change, if serious wear entire inner diameter slide calliper rule just can't use, cause the waste of material resources.
The utility model content
The purpose that the utility model will be realized is to be desirable to provide a kind of lengthening formula slide calliper rule that can measure different depth internal diameter or interior groove width.
The utility model is achieved through the following technical solutions above-mentioned purpose.
A kind of lengthening formula slide calliper rule comprise rule and slide block, and wherein slide block slides at rule, and rule is provided with mobile jib, and slide block is provided with secondary bar, are connected with extension rod respectively on mobile jib and the secondary bar.
This programme increases extension rod on the basis of original internal caliber gauge, thereby can measure internal diameter or the interior groove width of different depth, if the measuring position degree of depth of internal diameter or interior groove width is very dark, can also change longer extension rod, to satisfy the needs of measuring.So this programme has been widened the measurement range of original internal caliber gauge.
As further improvement, above-mentioned extension rod end reassembling type is equipped with measuring head, when measuring head has serious wear or damage and influences measuring accuracy, can change measuring head, scraps to avoid whole slide calliper rule, has reduced the waste of material resources.
As further improvement, an above-mentioned extension rod and mobile jib are slidingly connected, and another extension rod and secondary bar are slidingly connected.Extension rod and mobile jib and secondary bar are slidingly connected respectively, and extension rod can be made longerly slightly, then according to the position of measuring, regulate the length that extension rod stretches out mobile jib and secondary bar, so that measure, thereby can reduce or avoid changing extension rod, directly various parts be measured.
As a kind of concrete version, above-mentioned slide calliper rule also comprise two web members, and mobile jib is fixedlyed connected with web member respectively with secondary bar, and extension rod is slidingly connected with web member respectively.
As further improvement, above-mentioned web member comprises fixed block and the cover plate that is fixed together, and mobile jib and secondary bar are clipped in respectively mobile jib is fixedlyed connected with web member respectively with secondary bar.Why web member and mobile jib, web member and secondary bar are fixed, namely their relative position is fixed, rather than the relative mobile jib of web member and the slip of secondary bar, because web member itself generally can be wideer than extension rod, avoids web member to bring obstacle to measurement.
As further improvement, above-mentioned fixed block is provided with dovetail groove, and the xsect of above-mentioned extension rod is dove-tail, and extension rod slides in dovetail groove, and dovetail groove type is slidingly matched and makes slip more smooth and easy and precision is high; Above-mentioned web member also comprises lock dog, and lock dog is locked on cover plate or the fixed block by screw, and lock dog is provided with an inclined-plane, and the inclined-plane is adjacent to the side of extension rod, namely compresses extension rod by lock dog, makes it can not produce slip when measuring.
As further improvement, above-mentioned extension rod end is provided with through hole; Above-mentioned measuring head comprises head and afterbody, and head is cone, and afterbody is pin, and pin is provided with radial flange, and the pin end is provided with threaded hole; Pin stretches into through hole, and flange is stuck in an end of through hole, and the threaded hole internal lock has screw, and screw is pressed in the other end of through hole.When measuring head need be changed because of reasons such as wearing and tearing, only need back out screw, the measuring head that more renews, lock-screw gets final product again, and it is convenient to change.
The utility model compared with prior art mainly has following beneficial effect: by regulating the length that extension rod stretches out mobile jib and secondary bar, perhaps change extension rod, thereby expand the measurement range of slide calliper rule, internal diameter or the interior groove width of the multiple degree of depth are measured; Measuring head can be changed, and scraps to avoid whole slide calliper rule, has reduced the waste of material resources.The utility model can be measured the diameter of common diameter of bore and interior hole slot, the diameter of bore of all right more special easy interference in measuring position and the diameter of interior hole slot.
