Description
Technical field
The utility model relates to mechanical field, particularly, relates to a kind of pipe internal strain sheet paste tool.
Background technology
In some experimental studies, due to the particular design of test model, need to paste foil gauge at tube interior; For some sensors, need the inwall of strain gauge adhesion at deep hole.The circumferential angle of these foil gauges may be 90 ° or 180 °.The angle of strain gauge adhesion and position have a significant impact test figure and sensor accuracy, and therefore, the quality of strain gauge adhesion effect directly has influence on the reliability of test figure and the precision of sensor.
At present, " a kind of strain gauge adhesion mechanism " that Chinese patent CN2326948Y announces is made up of rubber tube, fixture and nut, this structure relies on axle pressure to cause rubber tube to expand, after rubber tube expands, radial pressure is less, be difficult to compress foil gauge, and this instrument once can only paste the foil gauge that two panels angle is 180 °; " a kind of metal strain plate paster apparatus " of CN202903127UY includes d-axis, land, connecting rod, push rod and paster seat, this paster apparatus volume is larger, obviously be difficult to use in the little inner walls of deep holes foil gauge paster of diameter to use, in addition, due to rod member transmissions such as this device connecting rod, push rods, the kinetic stability of paster seat will be affected, and also just have impact on the stickup angle stability of foil gauge; " a kind of strain gauge adhesion mechanism " of CN103438066A mainly comprises servomotor, line slideway, leading screw, slide block, F type moving base, upset cylinder, gas pawl, application head, telescopic cylinder, knife rest, blade.This apparatus structure is comparatively complicated, and processing cost is higher, after having pasted a slice foil gauge, adopts the rotation of upset 180 degree, cylinder, can only realize once pasting two foil gauges in hole; " a kind of inner walls of deep holes strain gauge adhesion frock for steel rolling sensor " of CN103527588A comprises body, positioning seat, ball valve, gas joint, body etc.This strain gauge adhesion frock can meet pastes the requirement that circumferential angle is 90 ° of foil gauges, but this frock need be equipped with gas drive power station and related Control System, and bulky, economy drops into high, is not suitable for generally using.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pipe internal strain sheet paste tool, this paste tool can simultaneously by the circumferential angle of specifying in multi-disc strain gauge adhesion to small-bore tubing and mouth of pipe depth, and the circumferential angle of foil gauge can be 90 ° or 180 °.
The technical scheme in the invention for solving the above technical problem is: a kind of pipe internal strain sheet paste tool, comprise inner hollow and the sleeve pipe of both ends open, one of them openend of described sleeve pipe is divided into some deciles along its diametric(al), and the port interior hollow section of this openend is prism shape, the inwall of sleeve pipe is processed into internal thread, and internal thread is communicated with the other end opening part of sleeve pipe; The outer wall of described sleeve pipe is sheathed with rubber blanket, and rubber blanket is linked in the equally divided position of sleeve pipe; Rotation push rod is provided with in described sleeve pipe, the one end rotating push rod is the prism structure cooperatively interacted with prism shape, the outer wall of the other end is provided with helicitic texture, and the internal thread of this helicitic texture and sleeve pipe screws, the outer wall of rotation push rod is provided with the spacing tip, the spacing tip is arranged between prism structure and helicitic texture, and the spacing tip is connected with helicitic texture.Existing inner when pasting foil gauge in the pipe of test model carrying out particular design, for some sensors, need the inwall of strain gauge adhesion at deep hole.The circumferential angle of these foil gauges may be 90 ° or 180 °.The angle of strain gauge adhesion and position have a significant impact test figure and sensor accuracy, and therefore, the quality of strain gauge adhesion effect directly has influence on the reliability of test figure and the precision of sensor.Therefore design specialized instrument is needed, can simultaneously by the circumferential angle of specifying in multi-disc strain gauge adhesion to small-bore tubing and the mouth of pipe degree of depth, the circumferential angle of foil gauge can be 90 ° or 180 °.This programme utilizes and ferrule openings end is divided into some deciles along its diametric(al), then under the effect of cooperatively interacting of prism shape and prism structure, rotating push rod rotation makes sleeve pipe strut along aliquot, by strain gauge adhesion to tube wall, spacing tip restriction rotates the rotation distance of push rod, avoid rotating after push rod proceeds to sleeve pipe completely and be inconvenient to screw out, the structure of threaded engagement has auto-lock function, increase the stability in the course of work, keeper to be stuck in pipe and to contact with tube wall, the angle of rotational positioning part is with regard to the change of implementation tool in tube interior angle, realize simultaneously by the circumferential angle of specifying in multi-disc strain gauge adhesion to small-bore tubing and the mouth of pipe degree of depth, the circumferential angle of foil gauge can be 90 ° or 180 °.
The outer wall of sleeve pipe is sheathed with keeper, and keeper is arranged on sleeve pipe one end away from the prism structure rotated in push rod; Keeper is provided with four wire lead slots, the center line of wire lead slot and the centerline parallel of sleeve pipe.Keeper and split coupling are by being welded to connect, and the effect of keeper is the installation direction of limit strain sheet.
Sleeve pipe, rotation push rod, the spacing tip and keeper are metal material and make; Sleeve pipe adopts spring steel to make.Metal material can ensure its hardness and serviceable life, spring steel makes inside pipe casing can recover in time after deformation, it has high yield strength, plastic yield is not caused when bearing heavy load, there is high fatigue strength, under load repeated action, there is long serviceable life, and have enough toughness and plasticity, in case unexpected brittle failure under impact force action, sleeve pipe is made can in use to keep stable.
Sleeve pipe is divided into the quartern near the openend of prism shape along its diametric(al).The quartern is best decile situation, utilize and prism shape is set to quadrangular, like this when prism structure rotates, the ferrule openings end of the quartern can back down by four crest line positions, making the foil gauge on rubber blanket and pipe racks inwall near to contacting, realizing pasting.
To sum up, the beneficial effects of the utility model are:
1, four foil gauges can be installed to the position of specifying in small-bore tubing, the circumferential angle between foil gauge can be 90 ° or 180 ° simultaneously;
2, simply, cost is little, easy to use for instrument manufacture, installation.
