Abstract
The invention discloses a pneumatic measuring head for the outer diameter of large workpieces, and belongs to measuring devices. According to the pneumatic measuring head for the outer diameter of the large workpieces, measuring head bodies can be separated from a whole measuring machine. The pneumatic measuring head for the outer diameter of the large workpieces comprises the two measuring head bodies communicated with air flues, wherein the air flues are air pipes (8) which are connected with the two ends of a tee-branch pipe (3) in parallel; the two measuring head bodies (6) are fixed to a connection rod (1); the connection rod is provided with a locating device; the locating device is composed of two slide rods (5) and locating heads (7) fixed to the slide rods (5) respectively; the slide rods are fixed to the connection rod (1) through threads. The pneumatic measuring head for the outer diameter of the large workpieces can effectively reduce the size and the weight of the whole machine, and ensure that the center line of an air hole of the measuring head is intersected with the center line of the outer circle of the workpieces, thereby improving the measuring precision. The pneumatic measuring head is used for measuring the outer diameter of the large workpieces.
Description
Technical field
The present invention relates to a kind of measurer, relate in particular to a kind of Pneumatic measuring head.
Background technology
As everyone knows, pneumatic gauging is take pressurized air as medium, workpiece size is carried out to a kind of technology of non-cpntact measurement; Its principle be according to measuring head during near surface of the work the pressure in gas circuit change, utilize pressure transducer that this pressure reduction is transformed into electric signal, then by data processing unit, this electric signal processed and shown result.At present, large-size workpiece external diameter air measuring device adopts built-in air flue conventionally; Because the built-in air flue of measuring head and this is fixedly connected with, therefore measuring head can not separate with complete machine, has the huge heaviness of one-piece construction, uses and carry the defects such as inconvenient.In addition, the air measuring device of traditional structure does not have locating device, is therefore difficult to guarantee that measuring head pore center line is crossing with excircle of workpiece center line, and measuring error is larger.
Summary of the invention
In order to overcome the defect existing in prior art, the present invention aims to provide a kind of measuring head can realize the large-size workpiece external diameter Pneumatic measuring head separating with measurement complete machine.
To achieve these goals, the present invention by the following technical solutions: it comprises two measuring heads that are communicated with air flue; Described air flue is the tracheae that is connected in parallel on three-way pipe two ends, and two measuring heads are separately fixed on connecting link; On this connecting link, have locating device, this locating device by being fixed on two slide bars on connecting link by screw thread, the positioning head being separately fixed on each slide bar forms.
On each slide bar, there is set nut, on each positioning head, have lock-screw; Outside surface on each positioning head has outwardly circular fin; On connecting link, be fixed with handle.
Compared with the prior art, the present invention is owing to having adopted technique scheme, by original built-in with changed external tracheae in the air flue of complete machine inside, and increased connecting link between two measuring heads; Therefore can realize separating of measuring head and complete machine, reduce the volume and weight of complete machine; In addition, owing to having increased locating device, therefore can guarantee that measuring head pore center line is crossing with excircle of workpiece center line, improve measuring accuracy.The present invention has the advantages such as volume is little, lightweight, dismounting is flexible.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Fig. 2 is that Fig. 1 is vertical view.
In figure: connecting link 1, lock-screw 2, three-way pipe 3, handle 4, slide bar 5, measuring head 6, positioning head 7, tracheae 8, set nut 9.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
As shown in Fig. 1～2: two tracheaes 8 are connected in parallel on the two ends of three-way pipe 3, two measuring heads 6 that are separately fixed at connecting link 1 two ends are communicated with corresponding tracheae 8 by hydraulic quick coupler (not shown) separately.The side of connecting link 1 is fixed with locating device, this locating device by being fixed on two slide bars 5 on connecting link 1 by screw thread, the positioning head 7 being separately fixed on each slide bar 5 forms; The position of change positioning head 7 on slide bar 5 is that the pore center line of adjustable measuring head 6 is crossing with excircle of workpiece center line.
In order to guarantee accurate positioning, on each slide bar 5, there is set nut 9, on each positioning head 7, there is lock-screw 2.In order to reduce contact area, the raising positioning precision of positioning head 7 and excircle of workpiece, the outside surface of each positioning head 7 has outwardly circular fin.
For the ease of carrying and operating, on connecting link 1, be fixed with handle 4.
Claims (5)
1. a large-size workpiece external diameter Pneumatic measuring head, comprises two measuring heads that are communicated with air flue; It is characterized in that: described air flue is for being connected in parallel on the tracheae (8) at three-way pipe (3) two ends, and two measuring heads (6) are separately fixed on connecting link (1); On this connecting link, have locating device, this locating device is made up of the positioning head (7) that is fixed on two slide bars (5) on connecting link (1) by screw thread, be separately fixed on each slide bar (5).
2. large-size workpiece external diameter Pneumatic measuring head according to claim 1, is characterized in that: on each slide bar (5), have set nut (9), have lock-screw (2) on each positioning head (7).
