Abstract
The utility model discloses a double-hammerhead electric hammer comprising a shell body, hammer rods, a transmission mechanism and a motor, wherein each hammer rod is arranged in the shell body and located at the front end of a piston, the transmission mechanism provides reciprocating power for the pistons, and the motor provides power for the transmission mechanism. The double-hammerhead electric hammer is characterized in that a bearing of the transmission mechanism is sleeved with a swing rod bearing, the two ends of the swing rod bearing both outwards extend, form shaft rods and are respectively provide with a cylinder pin, and cylinders which are respectively provided with a piston are matched with the cylinder pins respectively and correspond to the cylinder pins respectively. Due to the fact that the two ends of the swing rod bearing both extend outwards and form the shaft rods, the swing rod bearing can alternatively drive the two cylinder pins, and the hammer rods arranged in the pistons matched with the cylinder pins respectively can alternatively outwards conduct hitting movement. Therefore, the working efficiency can be improved when operation is conducted on the objects such as a thin concrete pavement and a thin wall.
Description
Technical field
The utility model relates to a kind of electric hammer, is specifically related to two tup electric hammers.
Background technology
Present electric hammer only has a tup, and its structure comprises housing, is installed on the hammer stem of being located at piston nose in housing, and the transmission mechanism of reciprocating power is provided for piston, and the motor of power is provided for transmission mechanism.Hammer stem and piston are man-to-man relations, a piston provides impact for a hammer stem, tup just easily makes the object fragmentation in body surface shock same point like this, but to objects such as thiner cement pavement or walls, only have a tup to use efficiency low, usually need use many electric hammer, a plurality of people operate and could fulfil assignment in the short period of time.
Summary of the invention
The purpose of this utility model is exactly ineffective problem in order to solve electric hammer and to cause on the objects such as the thiner cement pavement in surface or wall operation because of the structure of single tup.
The technical scheme that the utility model will be dealt with problems is as follows:
Two tup electric hammers, comprise housing, be installed on the hammer stem of being located at piston nose in housing, the transmission mechanism of reciprocating power is provided for piston, the motor of power is provided for transmission mechanism, it is characterized in that: all stretch out axostylus axostyle set the cylinder pin of the two ends of the Oscillating lever bearing that the bearing of described transmission mechanism is nested with, corresponding cylinder pin mates respectively the cylinder that piston is housed.
The beneficial effects of the utility model are as follows:
Compared with prior art, adopt two tup electric hammers of the utility model structure, because of the two ends of the Oscillating lever bearing axostylus axostyle that all stretches out, make Oscillating lever bearing can alternately urge two cylinder pins, and make hammer stem in the piston with cylinder pin coupling to replace outwards to do impulsive motion, for this reason can be on the objects such as thiner cement pavement or wall can increase work efficiency during operation.
The accompanying drawing explanation:
Fig. 1 is the structural representation of the two tup electric hammers of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is done to further detailed elaboration.
Consult Fig. 1, two tup electric hammers, comprise housing, be installed on the hammer stem of being located at piston nose (1) in housing, the transmission mechanism of reciprocating power is provided for piston, the motor (2) of power is provided for transmission mechanism, all stretch out axostylus axostyle set cylinder pin (5) of the two ends of the Oscillating lever bearing (4) that the bearing of described transmission mechanism (3) is nested with, corresponding cylinder pin (5) mates respectively the cylinder (6) that piston is housed.
The operation principle of described pair of tup electric hammer is as follows:
Motor (2) drives transmission mechanism and rotates, be nested with at the Oscillating lever bearing (4) on transmission mechanism bearing (3) because of the ball groove of the inboard spin of bearing on transmission mechanism bearing (3) as being obliquely installed, running will force bearing to move back and forth like this, and the axostylus axostyle of Oscillating lever bearing (4) end can drive cylinder pin (5) and in cylinder, does piston motion, the two ends of Oscillating lever bearing (4) replace before and after being, can realize that therefore two hammer stems (1) do alternating movement.
Claims (1)
1. two tup electric hammers, comprise housing, be installed on the hammer stem of being located at piston nose in housing, the transmission mechanism of reciprocating power is provided for piston, the motor of power is provided for transmission mechanism, it is characterized in that: all stretch out axostylus axostyle set the cylinder pin of the two ends of the Oscillating lever bearing that the bearing of described transmission mechanism is nested with, corresponding cylinder pin mates respectively the cylinder that piston is housed.
