Accompanying drawing explanation
Fig. 1 is the preferred embodiment structural representation of the floating type turning clamp of the two location of the present invention.
Fig. 2 is that the lateral axis of Fig. 1 is cutd open schematic diagram.
Fig. 3 is the structural representation of link member.
The specific embodiment
The present invention is directed to the larger problem of single-piece positioning clamp clamping link member difficulty in prior art, innovation has proposed a kind of floating type turning clamp of two location, the convenient and swift and accurate positioning of clamping link member.
As shown in Figure 1 to Figure 3, a kind of floating type turning clamp of two location, is applied to location and the turning of link member 1.Especially, link member 1 has locating hole 11, connecting rod 12 and arc groove 13, and the floating type turning clamp of two location comprises clamp body 2, two positioning unit 3 and telescopic axle sleeve mechanism 4.Wherein, two positioning units 3 are comprised of pin 31 and wedge clamp 32, clamp body 2 is provided with central channel 21 and pin-and-hole 22, telescopic axle sleeve mechanism 4 is installed on central channel 21, wedge clamp 32 is detachably installed in clamp body 2, pin 31 is fixed on pin-and-hole 22 through the locating hole 11 of link member 1, and wedge clamp 32 fixes the connecting rod 12 of link members 1, and the mandrel 41 of telescopic axle sleeve mechanism 4 connects with the arc groove 13 of link member 1.
Wherein, telescopic axle sleeve mechanism 4 comprises mandrel 41 and axle sleeve 42, and axle sleeve 42 is arranged at central channel 21, and mandrel 41, along axle sleeve 42 axial stretchings, positions for the arc groove to link member, vacates space and facilitate turning after simultaneous retractable.Axle sleeve 42 prolongs mandrel 41 approach axis and is provided with the first arc groove 51 and the second arc groove 52 separately, mandrel 41 is equiped with spring 61 and steel ball 62, mandrel 41 along steel ball 62 in axle sleeve 42 axial stretching processes under spring 61 drives respectively with the first arc groove 51 or the second arc groove 52 phase clampings, this telescopic axle sleeve mechanism structure is simple and easy, with low cost.
In addition, the lozenges of wedge shape briquetting 32 is 5o, for adapting to the thickness error of link member 1, after mandrel 41 retractions, still there is a rotational freedom in link member 1, in turning process, the cutting force by turning rotates and makes link member 1 and wedge shape briquetting 32 clampings firm.
During concrete enforcement, as shown in A in Fig. 2, the mandrel of telescopic axle sleeve mechanism is in stretching out state, the arc groove of link member and mandrel are connected, then the locating hole that passes link member by pin is fixed on pin-and-hole, link member is fixed on to clamp body, again by the connecting rod of wedge clamp stationary links part, after fixing, mandrel is bounced back, as shown in B in Fig. 2, the mandrel of telescopic axle sleeve mechanism is in retracted state, now the arc groove of link member is partly carried out to turning, turning direction is relative with the fixed-direction of wedge clamp, after turning, unload pin and wedge clamp and can obtain the complete link member of turning, repeat operation the production that can circulate.
The preferred embodiments of the present invention, clamp body is provided with three groups of two positioning units, can to three link members, position turning simultaneously, has further improved production efficiency, and has reduced equipment cost.
By above-mentioned character express, can find out, apply floating type turning clamp of the present invention, adopt two positioning units and telescopic axle sleeve mechanism link member to be positioned fixing, pass through stretching of telescopic axle sleeve mechanism simultaneously, facilitate turning, positioning action is convenient and swift, and accurate positioning, improve qualification rate and the production efficiency of turning processing, brought higher economic worth.
