Abstract
The invention discloses a pressure gauge for a diesel engine, which comprises a shell, a C-shaped tube, a copper connector, a balance spring, a machine core, an end socket, a connecting rod rivet, a connecting rod, a machine core rivet, a machine core screw, an instrument panel, a pointer and a limit pin. The pointer is arranged at the upper part of the machine core. The machine core is connected with the shell via the machine core screw. The copper connector is connected with the shell and is used for being connected with a to-be-measured object. The C-shaped tube is made of manganese copper alloy and has the advantages of good temperature resistance and good fatigue resistance. The C-shaped tube is connected with the connecting rod rivet through the pressure welding of the end socket. The connecting rod rivet is connected with the connecting rod. The connecting rod is connected with the machine core rivet. The machine core rivet is connected with the machine core. The balance spring is arranged inside the machine core. During installation, a certain pre-tightening force is applied onto the balance spring, and then the certain pre-tightening force is transmitted to the machine core via the balance spring. In this way, the machine core is driven to move and the steady transmission is enabled. When the pointer returns to zero, the pointer is prevented from bouncing. The limit pin is arranged on the shell and is used for limiting the pointer during the returning process.
Description
Technical field
The present invention relates to a kind of tensimeter, specifically a kind of tensimeter being applicable to diesel engine pressure source and measuring.
Background technology
In the prior art, operationally vibrate relatively more violent for measuring diesel engine, pressure source temperature is higher, very high to manometric technical requirement, and particularly C shape pipe ruptures often, the situations such as crackle; The welding manner simultaneously adopted at present is generally soldering and melting welding, welding production cost intensive, and pad easily cracks in dither, has influence on manometric serviceable life, and produces vibration when making the back to zero of pointer, spring.
Manage there being the C shape in prior art in tensimeter and usually adopt brass, tin-phosphor bronze, beryllium-bronze and stainless steel etc., the high temperature resistance of these materials and anti-fatigue performance are not the best, and welding performance neither be fine simultaneously.
Summary of the invention
For solving the technical matters existed in above-mentioned prior art, the object of this invention is to provide a kind of high temperature resistant, antidetonation, making zero effective, the tensimeter that welding technology is easily manufactured simultaneously.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of tensimeter of the present invention, comprise housing, C shape pipe, copper sleeve, hairspring, movement, end socket, link rivet, connecting rod, movement rivet, movement screw, table board, pointer, place restrictions on nail, described movement top is provided with pointer, and it is connected with housing by movement screw; Described copper sleeve is connected with housing, and it is for connecting the connection of testee; Described C shape pipe is flexible, and it is connected with link rivet by end socket, and link rivet is connected with connecting rod, and connecting rod is connected with movement rivet, and movement rivet is connected with movement; Described hairspring is installed on movement inside, gives the pretightning force that hairspring is certain during installation, and pretightning force is delivered on movement by hairspring, when movement is moved, and energy stable drive; Described nail of placing restrictions on is installed on housing, spacing for during pointer return.
Wherein, the material of described C shape pipe is manganin.
Wherein, the screw thread of described copper sleeve is metric thread, and can certainly be the thread forms of other specification, the present embodiment be preferably metric thread.
Wherein, described end socket is pressure welding end socket, adopts bond technology welding C shape pipe and link rivet.
By adopting such scheme, compared with prior art, tensimeter technique effect of the present invention is:
The material of C shape pipe is that manganin can be high temperature resistant, fatigue properties are fine, and adopt bond technology, heating-up temperature is lower than existing heating means, and the heat time is short, and heat-affected zone is little, simplify welding process, substantially increase welding efficiency and welding end socket mechanical property, therefore manometric more have shatter-proof, resistance to elevated temperatures.
The effect of pretightning force when hairspring is installed does not produce vibration spring when making cursor backward on earth, back to zero effect is fine.
Accompanying drawing explanation
Fig. 1 is for being the manometric package assembly schematic diagram of the present invention;
Fig. 2 is the manometric plan structure schematic diagram of the present invention;
To be that the present invention is manometric face structural representation to Fig. 3.
Embodiment
Below in conjunction with the embodiment shown in Fig. 1-3, the present invention is further illustrated:
As shown in one of Fig. 1 to Fig. 3: a kind of tensimeter of the present invention, comprise housing 1, C shape pipe 2, copper sleeve 3, hairspring 4, movement 5, end socket 6, link rivet 7, connecting rod 8, movement rivet 9, movement screw 10, table board 11, pointer 12, place restrictions on nail 13, described movement 5 top is provided with pointer 12, and it is connected with housing 1 by movement screw 10; Described copper sleeve 3 is connected with housing 1, and it is for connecting the connection of testee; Described C shape pipe 2 has elasticity, and it is connected with link rivet 7 by end socket 6, and link rivet 7 is connected with connecting rod 8, and connecting rod 8 is connected with movement rivet 9, and movement rivet 9 is connected with movement 5; It is inner that described hairspring 4 is installed on movement 5, and give the pretightning force that hairspring 4 is certain during installation, pretightning force is delivered on movement 5 by hairspring 4, when movement 5 is moved, and energy stable drive; Described nail 13 of placing restrictions on is installed on housing 1, spacing for during pointer return.
Wherein, the material of described C shape pipe 2 is manganin.
Wherein, the screw thread 31 of described copper sleeve 3 is metric thread, and can certainly be the thread forms of other specification, the present embodiment be preferably metric thread.
Wherein, described end socket 6 is pressure welding end socket, adopts bond technology welding C shape pipe 2 and link rivet 7.
As shown in one of Fig. 1 to 3:
In practical work process of the present invention, first, pressure source gives C shape pipe 2 pressure C shape pipe 2 is out of shape, C shape pipe 2 is out of shape rear drivening rod 8, connecting rod 8 drives movement 5 again, and the pointer 12 be connected on movement 5 just produces rotation, and pointer 12 indicates corresponding force value at table board 11; When pressure source pressure is 0, C shape pipe 2 loses applied external force, start resilience, C shape pipe 2 drivening rod 8, connecting rod 8 drives movement 5 again, the pointer 12 be connected on movement 5 just produces revolution, meanwhile, the pretightning force when hairspring 4 being arranged on movement 5 inside is installed acts in the process simultaneously, limited non-magnetic shim 13 spacing side when making pointer 12 be turned back to the end, and not producing vibration spring, back to zero effect is fine.
The foregoing is only preferred embodiment of the present invention, not in order to limit the scope of the invention, within the spirit and principles in the present invention all, any amendment done, equivalent to replace, be all included within protection scope of the present invention.
