Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that thisThe protection domain of invention is not subject to the restriction of detailed description of the invention.
Unless separately there is other clearly to represent, otherwise in whole description and claims, term " bagDraw together " or its conversion element of stating being understood to include as " comprising " or " including " etc. orPart, and do not get rid of other element or other part.
As shown in Figures 1 to 3, according to the pressure box fastener of a kind of precoated sand swage of the specific embodiment of the invention,It comprises: grooved button 1, mount pad 2, rotating nut 3, clamping screw 4 and pressure case loose piece 5, itsIn:
As shown in Figure 1, the lower end of grooved button 1 is provided with the hook portion 11 of protruding to a side, and grooved button 1Upper end be provided with the arm beam 12 that extends out and be positioned at hook portion 11 tops, whole grooved button 1 is integrally formed;Arm beam 12 is provided with a through hole corresponding with hook portion 11, and the inwall of this through hole convexes with a feather key.
As shown in Figure 1, mount pad 2 is fixedly installed on the upper end of arm beam 12; Preferably, mount pad 2 wrapsDraw together lower installation board 21 and upper mounting plate 22, lower installation board 21 is fixedly installed in arm beam by the mode of welding12 upper end; Preferably, as shown in Figure 2, the two sides of the bottom of lower installation board 21 and arm beam 12 itBetween respectively welding be provided with two reinforcements 7, can improve intensity by reinforcement 7, increase service life.As shown in Figure 1, upper mounting plate 22 is fixed on lower installation board 21 by screw in the mode that can dismantleUpper end, the middle part of the upper end of lower installation board 21 is concaved with first groove, and establish the lower end of this first grooveBe equipped with corresponding with through hole on the arm beam 12 nail hole of crossing, the middle part of upper mounting plate 22 is corresponding to lower installation boardThe middle part of 21 lower end is concaved with another second groove corresponding with the first groove of lower installation board 21, shouldThe upper end of the second groove is provided with opening. After upper mounting plate 22 is installed on lower installation board 21, firstGroove and the second groove form a cavity.
As shown in Figure 1, the lower end of rotating nut 3 is provided with screw, and the lower end of rotating nut 3 is by oneThrust ball bearing 31 is arranged in the mode that can rotate the sky that upper mounting plate 22 and lower installation board 21 formIn chamber, and top is extended through the opening of upper mounting plate 22 in the upper end of rotating nut 3. Preferably. TurnThe upper end of moving nut 3 is connected with one handle 6. Because upper mounting plate 22 can be dismantled, therefore convenient to rotatingMaintenance, maintenance or the replacing of nut 3 and draft ball bearing. By the work of handle 6 and thrust ball bearing 31With, can control more effortlessly rotating nut 3 and rotate, thereby reduce workman's labour intensity, and canIt is enough and even that guarantee tightens power, avoids occurring foundry goods floating because swage does not press tightly, and causes butterfly-shaped shortbread and liftCase phenomenon, and cause that foundry goods burr is many and surplus is large, thus promote casting qualified rate.
As shown in Figure 1, the sidewall of the bottom of clamping screw 4 is concaved with a keyway corresponding with feather key;The screw of the top of this clamping screw 4 and rotating nut 3 lower ends is connected with a joggle, and this clamping screw 4The through hole that hole and arm beam 12 are followed closely through the mistake of lower installation board 21 in lower end is to extend the below of arm beam 12. AndThe feather key active card of the through hole on arm beam 12 is embedded in the keyway of clamping screw 4 lower ends, so that this compressionScrew rod 4 is merely able to make upper and lower linear slide along through hole, and can not rotate, thus turning by rotating nut 3Move to control sliding up and down of clamping screw 4. The thread type of rotating nut 3 and clamping screw 4 comprisesTriangle thread, trapezoidal thread and left-handed and dextrorotation, can select both according to concrete applying working conditionThread type and rotation direction.
As shown in Figure 1, pressure case loose piece 5 is fixedly installed on the lower end of clamping screw 4, the face of its lower surfaceThe area of the long-pending radial section that is greater than clamping screw 4; Preferably, the material of this pressure case loose piece 5 is stainlessSteel, the transmission of its energy retarding heat. Preferably, the upper end of pressure case loose piece 5 is sheathed on clamping screw 4Lower end, and press the upper end of case loose piece 5 to be fixedly connected with by a latch 51 with the lower end of clamping screw 3, insertPin 51 is locked with elastic washer 52 by an axle, to facilitate the dismounting of pressing case loose piece 5. Pressure case is livedPiece 5 is followed clamping screw 4 and is made upper and lower rectilinear motion, and when tight case, clamping screw 4 drives presses case loose piece 5Move downward, thereby by pressing case loose piece 5 and hook portion 11 compresses and fixing swage 8. As shown in Figure 3,Swage 8 comprises swage 81 and lower swage 82, and the two sides of these two swages are equipped with guide rail 83. ExcellentSelection of land, presses case loose piece 5 to be pressed in guide rail 83 upper surfaces of swage 81, and hook portion 11 catches on lower swage 82Guide rail 83 lower surfaces. The area of pressure case loose piece 5 is greater than the area of section of clamping screw 4, therefore its increasePressure case area, reduced active force, can reduce labour intensity, and press case loose piece 5 can delay swage 8Heat directly pass on clamping screw 4, improved the service life of clamping screw 4. In addition, press caseLoose piece 5 can also be avoided damaging guide rail 83, plays the effect of protection.
The present invention is driven the rotation of rotating nut 3 by handle 6, thereby makes clamping screw 4 be with dynamic pressure case to livePiece 5 moves up and down to realize tight case or the action of loose case to upper swage 81 and lower swage 82. It can be preventedStop loss bad swage 8 and clamping screw 4, reduce workman's labour intensity,
The aforementioned description to concrete exemplary of the present invention is in order to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentionedInstruction, can much change and change. Exemplary embodiment is selected and the object described existsIn explaining certain principles of the present invention and practical application thereof, thereby make those skilled in the art can be realNow and utilize various exemplary of the present invention and various selection and change.Scope of the present invention is intended to be limited by claims and equivalents thereof.
