The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As Fig. 1, Fig. 2 and shown in Figure 3, the anchor clamps that are used for milling half-moon groove of the present invention, comprise: base 1, a pair of journal stirrup 3 and a pair of platform 14 of shelving that described base 1 is provided with locating shaft 2 and is positioned at locating shaft 2 both sides, the top of each journal stirrup 3 offers the pressing plate groove, be movably set with pressing plate 5 by bearing pin 4 in each pressing plate groove, its concrete structure is: offer the pin shaft hole that matches with bearing pin 4 respectively in the both sides sidewall of pressing plate 5 and pressing plate groove, described bearing pin 4 passes from the pin shaft hole of the sidewall on pressing plate groove right side and pressing plate 5 successively, stretch in the pin shaft hole of left side sidewall of pressing plate groove; Also be provided with the support and the hydraulic cylinder 13 that constitute by four root posts 7 on the base 1, four root posts, 7 upper supports have location-plate 8, the a pair of clamp arm 6 that is symmetrically distributed in a pair of journal stirrup 3 both sides is movably arranged on the location-plate 8 by the mandrel 9 that is located in its mandrel hole 61 respectively, four root posts 7 are positioned at the outside of a pair of clamp arm 6, the front portion of each clamp arm 6 is shelved on shelves on the platform 14 accordingly, and be provided with the clamping inclined-plane 64 that matches with pressing plate 5, as shown in Figure 4, offer clamping slot 63 on the end face at each clamp arm 6 rear portion, form a pair of supporting arm, offer a pair of clamping pin-and-hole 62 that cooperatively interacts in every pair of supporting arm, be equipped with a holding pin 10 in every pair of clamping pin-and-hole 62, be provided with between two holding pins 10 and be used to strain the back-moving spring 15 that two clamp arms 6 come closer---referring to Fig. 1, shown in Figure 2, in addition, also be provided with on the outer lateral side of clamp arm 6 be used to dodge column 7 dodge groove 65, the piston rod 12 of hydraulic cylinder 13 is provided with the voussoir 11 that matches with a pair of clamp arm 6, as shown in Figure 5, one end of voussoir 11 is provided with connecting rod 111, connecting rod 111 is embedded in the piston rod 12, and two hypotenuses 112 of voussoir 11 inboards embed respectively in the corresponding clamping slot 63, and be pressed on the holding pin 10.In the present embodiment, in clamping slot 63, be provided with roller 16---referring to shown in Figure 1, roller 16 is sleeved on the holding pin 10 and two hypotenuses 112 of voussoir 11 inboards are pressed on the roller 16.
