Utility model content
The purpose of this utility model is, for above-mentioned defect of the prior art, to provide a kind of follow-on inner diameter measuring device of the internal diameter size of measuring irregular circular hole.
For realizing above-mentioned utility model object, the utility model has adopted following technical scheme: a kind of inner diameter measuring device, comprise measuring head, gauge outfit and be connected to measuring head and gauge outfit between sounding rod, it is characterized in that: described measuring head comprises main component and the measurement bay matched with main component, described measurement bay comprises at least two expansion links, in the time that described inner diameter measuring device is measured irregular circular hole, described expansion link and described irregular circular hole lean.
In addition, the utility model also provides following attached technical scheme:
Described measurement bay also comprises web member, and described web member and described main component are matched, and described expansion link telescopically is connected on described web member.
Described web member comprises threaded portion, and described expansion link is threaded mutually with described threaded portion.
Described web member also comprises clamping part, and described main component comprises connector, and described clamping part is removably connected mutually with connector.
The shape of described measuring head is roughly Y type.
Inner diameter measuring device is internal diameter lever indicator, can measure the internal diameter of the irregular circular hole of pump plate.
Than prior art, advantage of the present utility model is: the measuring head of inner diameter measuring device provided by the utility model (internal diameter lever indicator) comprises main component and the measurement bay matched with main component, this measurement bay comprises at least two expansion links, in the time that inner diameter measuring device is measured irregular circular hole, expansion link and irregular circular hole lean.So inner diameter measuring device of the present utility model can be measured the internal diameter size of irregular circular hole exactly, such as the internal diameter of the irregular circular hole of pump plate.

Embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solutions of the utility model are further non-limitingly described in detail.
From Fig. 2 to Fig. 4, the inner diameter measuring device of corresponding the utility model preferred embodiment is internal diameter lever indicator, and it has measuring head 30, and this measuring head 30 comprises main component 3 and measurement bay 6.
Particularly, as seen from Figure 2, main component 3 two ends arrange respectively connector 4 and movable head 5.Wherein, connector 4 is made up of screw rod 4a and nut 4b, and screw rod 4a is fixedly installed on main component 3, and nut 4b is threaded mutually with screw rod 4a, can on screw rod 4a, move by spiral.Movable head 5 telescopicallies are arranged on the other end that is opposed to connector 4 on main component 3, measuring when internal diameter, the inwall of movable head 5 and measured hole mutually against, there is straight line contractile motion.Middle part at main component 3 is also provided with connecting hole 14, and this connecting hole 14 is removably connected mutually with one end of table bar (not shown), and the other end of table bar is removably connected mutually with gauge outfit (not shown) again.The straight line contractile motion of movable head 5 passes to table bar, and transmission is to gauge outfit again for table bar, and gauge outfit is just converted to the straight-line displacement of movable head 5 position, angle of pointer, so the reading of gauge outfit is the internal diameter of measured hole.
As shown in Figure 3, measurement bay 6 comprises web member 7 and a pair of expansion link 8.Wherein, the shape of web member 7 is roughly the cylindrical of hollow, and clamping part 9 is set on it, and a pair of threaded portion 10.Expansion link 8 is threaded mutually with threaded portion 10, so expansion link 8 is by screw thread rotation, adjustable and retractable bar 8 reaches the length outside web member 7, and this has angle M to expansion link 8.
As shown in Figure 4, main component 3 and measurement bay 6 mutually connect and form an overall measuring head 30.Installation step is: first the screw rod 4a on main component 3 extend in measurement bay 6 from clamping part 9, then, and by nut 4b precession screw rod 4a.Along with constantly screwing of nut 4b, together with 3 of main components are mutually permanently connected with measurement bay 6.Because the quantity of expansion link 8 is two, so after main component 3 and measurement bay 6 are mutually permanently connected, the shape of measuring head 30 is roughly Y type, measuring head 30 in the present embodiment is mainly for the pump plate of the spinning pump of 5 outlets, so this angle M to expansion link 8 is 72 °, and in the time measuring internal diameter, this must keep identical to the length of expansion link 8.Certainly, the angle M of expansion link 8 can change along with measuring the open amount of pump plate, and such as in the time that the opening of pump plate is 3, the angle M of expansion link 8 is 120 °, and the size of the angle M of expansion link 8 equals 360 ° of opening numbers divided by pump plate.
Fig. 5 is this inner diameter measuring device work schematic diagram while measuring the pump plate 1 of spinning pump, and as seen from the figure, this pump plate 1 centre position is provided with a large through-hole 23, and 5 small through hole 24 crossing with this large through-hole 23 are set around large through-hole 23.Because large through-hole 23 is mutually crossing with small through hole 24, so after setting completes, large through-hole 23 is interconnected with small through hole 24, and between it, has formed several convex edges 20, and large through-hole 23 has formed an imperfect and irregular circular hole again simultaneously.This inner diameter measuring device is arranged in large through-hole 23, so the movable head 5 of main component 3 and the expansion link 8 of measurement bay 6 can stably be resisted against on convex edge 20, because expansion link 8 angles of measurement bay 6 are 72 °, and this equal in length to expansion link 8, so this measuring head 30 can be measured the internal diameter of large through-hole 23 accurately, and demonstrate concrete data by gauge outfit.
It is to be noted; above-mentioned preferred embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
