The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the equal pressuring template that a kind of clamping torque described in the utility model is controlled, position according to tested valve mounting screw on the valve plate 1 is provided with four piston holes, the duct of perforation is arranged at the top of piston hole, be full of fluid in the duct, make piston be in the below, guarantee that piston has suitable displacement.Plug screw 2, plug screw 8, packing ring 9 are enclosed in the piston hole of valve plate with fluid and connect in the duct.Piston 3 has been installed in the piston hole, piston 3 relies on back-up ring 4, sealing ring 5 on the piston to realize with the sealing of the piston hole of valve plate, the piston exposed parts is designed to the shape consistent with mounting screw, the minor diameter that exposes is equivalent to the nominal diameter of mounting screw, can stretch into tested workpiece the screw location is installed, the major diameter that exposes is equivalent to the styletable diameter of interior hexagonal mounting screw, can compress the installation counterbore step of tested workpiece.Cover plate 6 is installed on the valve plate by screw 7, and cover plate can prevent that piston from deviating from, and the guiding that the through hole on the cover plate can be used as the piston external part makes the piston bottom link up with extraneous simultaneously.
As shown in Figure 5, oil cylinder 12-1,12-2 connect the equal pressuring template (compressing bascule) of two cover band pressure sensors respectively, when the oil-feed of oil cylinder epicoele, fast moving, after being with equal pressuring template contact workpiece, contact load makes pressure raise, and adopts this moment low discharge to keep thrust, and the epicoele that hydraulic oil enters oil cylinder only is used for replenishing the thrust of leakage rate to keep requiring.
All the structure oil cylinder that a potential energy is designed to compress one or more tested workpiece of compressing of pressuring template moves and once can finish tested Work-sheet pressing or loosen.Equal pressuring template (compressing bascule) gone up device 11-5,11-6 pressure sensors, the oil pressure that can monitor equal pressuring template closed chamber in real time changes, and guarantees that the pressure of equal pressuring template transmission enough satisfies the thrust of test piece needs.
Different workpiece have been stipulated different mounting torques according to working condition, should install to obtain good performance by moment of torsion in accordance with regulations during test.Adopt the utility model device, all pressuring template needs only the pressure of adjusting compressed oil cylinder, 11-5,11-6 pressure sensor just can identify, when reaching the force value of setting, can stablize the output thrust to the pressure pressurize of hydraulic system, realize that clamping torque is controlled.
All the piston upper chamber of pressuring template (compressing bascule) connects with the duct that is communicated with, and be full of the bigger fluid of stickiness or grease in the duct and form airtight oil pocket, the plug screw shutoff of the oral area of oil pocket, technology is simple, is difficult for leaking, and is reliable and stable.The sealing ring of piston and the piston hole on the valve plate seal the fluid of epicoele, and cavity of resorption does not have sealing device and communicates with atmosphere, and piston forms free body.
When compressed oil cylinder descending, be with equal pressing plate descending, the external part contact workpiece of the piston 3 on the equal pressing plate, piston moves up, the fluid in the compression closed chamber, and all pressing plate closed chamber pressure raises, because the epicoele of piston 3 communicates, the closed chamber internal pressure of piston top pressurized is evenly to transmit, and piston can be according to homing vector each contact point that compresses of the height situation of contact point, and transmits identical thrust to each contact point.Along with the compressed oil cylinder upper cavity pressure raises, pressure rises to setting value, reaches the requirement that compresses torsional moment, the sensor sender, and the compressed oil cylinder pressurize, tested workpiece is reliably compressed.
Cover plate 6 is used for preventing that piston from deviating from, and the guiding that the hole on the cover plate can be used as the piston external part is in communication with the outside the piston below simultaneously.
The utility model compared with prior art has following advantage:
1. this equal pressuring template (compressing bascule) is with the alternative trip bolt of styletable that piston stretches out, durable in use.Piston is assemblied in the valve plate, and structure, the size of the external part of piston (exposed parts) are identical with trip bolt, adapts to the fastening requirement of installation of tested workpiece.
2. valve plate arranges piston hole by the installation site size of tested workpiece, all on the pressuring template a plurality of pistons can be set, and realizes once compressing of a plurality of tested workpiece.
3. hole link is arranged at the piston hole top that arranges on the valve plate, be full of fluid (grease) in the cavity volume that is communicated with and the duct, behind the piston pressurized, connected pore channel by piston area top with the fluid in the closed chamber (grease) with equalization of pressure and be passed to each piston simultaneously, for each compresses the thrust that a little provides identical, realize all pressing.
4. the function that has automatic elimination workpiece installing hole depth error.The counterbore of workpiece certainly exists depth error in process, when using single screw, can eliminate the influence of these errors, but these errors must cause the difference of each point position thrust when using integral mold plate once to compress, and cause that the distortion of tested workpiece or thrust are not enough or excessive.The utility model adopts and is communicated with the airtight cavity volume that oil circuit makes a perforation of a plurality of plunger shaft formation, transmits the oil pressure that equates, the equal thrust of output when piston area is consistent.The displacement energy of piston under oil pressure eliminated the depth error of workpiece counterbore automatically to the influence of thrust.
5. all pressuring template is self-contained unit, and the piston that is compressed after the template by template by compressed oil cylinder transmits pressure to workpiece, regulates the pressure of compressed oil cylinder and has just adjusted the thrust that equal pressuring template transmits tested workpiece, thereby realize that clamping torque is adjustable, controlled.
6. compressed oil cylinder can once compress a plurality of equal pressuring templates, can once realize compressing many tested workpiece.
7. the sensing device that arranges on the equal pressuring template can directly read oil pressure pressure, monitors the mounting torque of tested workpiece in real time, realizes automatically-controlled continuous.
8. because all pressing plate inner carrier displacement is very little, adopted the big fluid of viscosity or grease to transmit oil pressure, sealing technology is simple, and leakage rate is minimum, uses reliable and stable.
9. all pressuring template adopts the common iron manufacturing, and is simple and reasonable for structure, processing, easy to maintenance, durable in use.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
