Summary of the invention

In order to address the above problem, the utility model provides a kind of clamp mechanism of excavator swing arm, this mechanism adopts the two clamping plates seat to be tightened on a double rotational directions screw rod, by interaction and then the quick opening and closing clamping function of realizing securely again the clamping plate seat of the parts such as handle, guide rail, lock-screw, degree of tightness is in order to change the clip position of swing arm very easily.

For achieving the above object, concrete scheme of the present utility model is:

a kind of clamp mechanism of excavator swing arm, comprise base, the double rotational directions screw rod, two clamping plate seats in opposite directions, there is end casing at two ends at described base, the both ends of described double rotational directions screw rod are rotating being supported on two end cover plate respectively, therein the lateral surface of an end casing have one with the fixing handle of double rotational directions screw rod, at the two ends of described double rotational directions screw rod, the opposite thread segment of rotation direction is arranged respectively, the middle part of the bottom of described two clamping plate seats is threaded with two thread segments of double rotational directions screw rod respectively, the two ends of the bottom of described two clamping plate seats slidably are supported on base respectively, and can be fixed by the locking member that passes the clamping plate seat between described two clamping plate seats and base, on two clamping plate seats plate face in opposite directions, clamp pin is arranged respectively.Here on the excavator swing arm that will clamp, the hole of matching with clamp pin should be arranged.

Two ends in the bottom of described two clamping plate seats are fixed with respectively ram, longitudinal direction has chute in the bottom surface of described ram, respectively there is a V-type tooth that protrudes the two sides of described chute, be fixed with two guide rails on described base, respectively there is the V-type groove side of described two guide rails, described chute supported is on guide rail, and the V-type tooth of described ram is embedded in the V-type groove, and described two clamping plate seats can slide along the V-type groove by the V-type tooth.

The sawtooth that continuous distributed is arranged at the upper surface of described guide rail, described locking member are lock-screw, can be fixed by the lock-screw that passes the clamping plate seat respectively between two guide rails of described two clamping plate seats and base.

The utility model is simple in structure, and degree of tightness so that the clip position of change swing arm is simple to operate, has been saved the time very easily, has improved operating efficiency.

Description of drawings

Fig. 1 is perspective view of the present utility model;

Fig. 2 is the perspective view of ram;

Fig. 3 is the perspective view of guide rail.

In figure: base 1, end casing 1-1, double rotational directions screw rod 2, thread segment 2-1, clamping plate seat 3, clamp pin 3-1, handle 4, ram 5, chute 5-1, V-type tooth 5-2, guide rail 6, V-type groove 6-1, sawtooth 6-2, locking member 7.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further described.

Referring to Fig. 1~Fig. 3, a kind of clamp mechanism of excavator swing arm comprises base 1, double rotational directions screw rod 2, two clamping plate seats 3 in opposite directions.

At the two ends of base 1, end casing 1-1 is arranged, the both ends of double rotational directions screw rod 2 are supported on two end cover plate 1-1 by bearing is rotating respectively, at one end the lateral surface of cover plate 1-1 have one with the fixing handle 4 of double rotational directions screw rod 2, the opposite thread segment 2-1 of rotation direction is arranged respectively at the two ends of double rotational directions screw rod 2, the middle part of the bottom of two clamping plate seats 3 is threaded with two thread segment 2-1 of double rotational directions screw rod 2 respectively, on two clamping plate seats 3 plate face in opposite directions, clamp pin 3-1 is arranged respectively.

Two ends in the bottom of two clamping plate seats 3 are fixed with ram 5 by screw respectively, longitudinal direction has chute 5-1 in the bottom surface of ram 5, respectively there is a V-type tooth 5-2 who protrudes the two sides of chute 5-1, be fixed with two guide rails 6 by screw on base 1, respectively there is V-type groove 6-1 the side of two guide rails 6, chute 5-1 is supported on guide rail 6, and the V-type tooth 5-2 of ram 5 is embedded in V-type groove 6-1, and two clamping plate seats 3 can slide along V-type groove 6-1 by V-type tooth 5-2.
