Abstract
The utility model discloses a U-shaped clamp with the function of clamp force display, which is composed of a U-shaped clamp body (3) and an elastic force testing clamp head. The utility model is characterized in that the elastic force measuring clamp head comprises a movable pressure head (4), a pull rod (5), a value indication sleeve (7), a pressure exerting nut (8), a compression spring (6) and an adjustment head (9). As a screwing force is gradually applied on the pressure exerting nut (8) on the pull rod (5), the compression spring (6) counters the pressure from the head-to-head movement between the value indication sleeve (7) and the movable pressure head (4) by generating a pressure to drive the movable pressure head (4) to tightly clamp a plurality of layers of nonmetal materials, and the scale mark in line with the end surface (10) of the value indication sleeve (7) indicates the clamp force. Therefore, the clamp force can be effectively controlled in the process of glue jointing nonmetal materials, and the glue joint is stable and reliable.

The utility model has following good effect than prior art.Screw the nut of exerting pressure on the pull bar with spanner, make indicating value sleeve and movable pressure head move toward one another, thereby make compression spring pressurized produce pressure, compression spring promotion activity pressure head clamps multilayer nonmetallic materials part.The power value is exactly the value that acts on the pressure on the compression spring, the just value of clamping force shown in the graduation mark of indicating value sleeve end face alignment this moment.Just can effectively control the clamping force size like this in glueing joint the operation of assembling nonmetallic materials, bonding quality is reliable and stable.
Description of drawings
Fig. 1 is a kind of cramp frame schematic diagram that shows clamping force of the present utility model.
Fig. 2 is a kind of movable pressure head schematic diagram that shows the cramp frame of clamping force of the present utility model.
Fig. 3 is former common cramp frame schematic diagram.
The specific embodiment
Below in conjunction with embodiment the utility model is further described.
Fig. 1, Fig. 2 is a kind of schematic diagram that shows the cramp frame of clamping force of the present utility model, form by cramp frame concrete 3 and elasticity dynamometry chuck, described cramp frame concrete 3 is one " U " shape metallic objects, left end has a plane, right-hand member has a horizontal screwed hole, the axis normal in hole is in the left end plane, it is characterized in that: described elasticity dynamometry chuck comprises movable pressure head 4, pull bar 5, indicating value sleeve 7, the nut 8 of exerting pressure, compression spring 6, regulate 9, described movable pressure head 4 is cylinders, the cavity 11 of the section of having radial opening in the tube, movable pressure head 4 is buckled in concrete 3 right-hand members of cramp frame, and horizontal screwed hole included in the cavity 11 by opening, one end and the concrete 3 left end planes of cramp frame of movable pressure head 4 form a pair of clamping area, place a compression spring 6 in the other end endoporus 12 of movable pressure head 4, the bottom surface of endoporus 12 has aperture and cavity 11 to connect, periphery carved graduation mark and marks the corresponding force value along the circle spacing, described pull bar 5 is studs, pull bar 5 passes compression spring 6, be connected with the horizontal screwed hole of concrete 3 right-hand members of cramp frame in the cavity 11 by aperture, the other end of pull bar 5 is inserted in indicating value sleeve 7, indicating value sleeve 7 intracavity diameters are slightly larger than the outside diameter of movable pressure head 4, indicating value sleeve 7 is enclosed within on the movable pressure head 4, the bottom contacts with compression spring 6, be inserted in the position display power value of end 10 in the graduation mark scope of movable pressure head 4 peripheries by indicating value sleeve 7, pull bar 5 stretches out indicating value sleeve 7 ends and tightens up with the nut 8 of exerting pressure, but the face of the exerting pressure shimming of the nut 8 of exerting pressure, clamping area one end of described movable pressure head 4 can be made external screw thread, put one and regulate 9, described adjusting 9 is thread bush, the scope of the tight opening size of rotation screw thread adjustable clamp.Screw the nut 8 of exerting pressure on the pull bar 5 with spanner, make indicating value sleeve 7 and movable pressure head 4 move toward one another, thereby make compression spring 6 pressurizeds produce pressure, compression spring 6 promotion activity pressure heads 4 clamp nonmetallic materials part 1 and the part 2 that glueds joint.The graduation mark or the power value shown in the position of indicating value sleeve 7 end faces 10 alignment this moment are exactly the force value that acts on the compression spring 6, the value of clamping force just, just can effectively control the clamping force size like this in glueing joint the operation of assembling nonmetallic materials, bonding quality is reliable and stable.
