A kind of drilling machine hydraulic clamp
Technical field
The utility model relates to a kind of drilling machine hydraulic clamp.
Background technology
In the whole processing technology of aluminium alloy wheel hub, wherein there is one to be drill centers, need to use drilling machine, before holing for wheel hub, to wheel hub be clamped with the scroll chuck on the drilling machine, existing scroll chuck needs the hand rotation spanner, manually stepping up has this bigger influence to employee's operating efficiency, one people can only operate a drilling machine, and workload is big, and employee's physical demands is also big, serious waste of manpower resource, if there is not clamping wheel hub, also security incident can appear when boring.
The utility model content
The purpose of this utility model is to provide a kind of drilling machine hydraulic clamp, and the clamping device that can effectively solve existing drilling machine needs manual operation, wastes time and energy, and operates the problem that also occurs security incident easily not in place.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of drilling machine hydraulic clamp, comprise support, scroll chuck, described scroll chuck is arranged on the support, also comprise platen, transmission mechanism, described platen rotates on the support that is arranged on below the scroll chuck, uniform three slide block slots that are obliquely installed of described platen, described slide block slot is a straight trough, also is provided with the rotation slot of a circular arc on the described platen, and an end of described transmission mechanism is arranged in the rotation slot, described scroll chuck comprises claw, slide block and chuck, described chuck is fixed on the support, and claw is arranged on the slide block, and described slide block is arranged in the slide block slot.
Preferably, described scroll chuck also comprises guide block, is evenly equipped with three gathering sills on the described chuck, is provided with guide block in each gathering sill, is fixed with claw on the described guide block, and described guide block also is fastenedly connected with slide block; When platen rotates, drive slide block, guide block is moved in gathering sill, drive claw and do rectilinear motion.
Preferably, described slide block comprises slide bar and is arranged on the connecting plate on slide bar top that described slide bar is arranged in the slide block slot, offers some screwed holes that are connected with guide block on the described connecting plate; Can well in slide block slot, slide, again can be well and guide block be connected and fixed.
Preferably, described transmission mechanism is a hydraulic cylinder, and an end of described hydraulic cylinder rotates and is arranged on the support, and the other end of described hydraulic cylinder is provided with dwang, and an end of described dwang is arranged in the rotation slot of platen; Adopt the hydraulic control dependable performance.
Preferably, described claw is provided with three steps; The wheel hub that adapts to different size.
Compared with prior art, the utility model has the advantages that: need not manually to tighten chuck, a people can operate two drilling machines simultaneously, raise the efficiency and saved human resources simultaneously, and clamp speeds is faster, and clamping force is also big than artificial clamping, has avoided the accident that may cause inadequately because of clamping force.

The specific embodiment
Consult Fig. 1, Fig. 2 is the embodiment of a kind of drilling machine hydraulic clamp of the utility model, a kind of drilling machine hydraulic clamp, comprise support 1, scroll chuck, described scroll chuck is arranged on the support 1, also comprise platen 3, transmission mechanism 4, described platen 3 rotates on the support 1 that is arranged on below the scroll chuck, as shown in Figure 3, described platen 3 uniform three slide block slots that are obliquely installed 31, described slide block slot 31 is a straight trough, also be provided with the rotation slot 32 of a circular arc on the described platen 3, one end of described transmission mechanism 4 is arranged in the rotation slot 32, described scroll chuck comprises claw 21, slide block 22 and chuck 23, as shown in Figure 4, described chuck 23 is fixed on the support 1, claw 21 is arranged on the slide block 22, described slide block 22 is arranged in the slide block slot 31, as Fig. 7, shown in Figure 8, described slide block 22 comprises slide bar 221 and is arranged on the connecting plate 222 on slide bar 221 tops, described slide bar 221 is arranged in the slide block slot 31, offer some screwed holes that are connected with guide block 24 on the described connecting plate 222, described scroll chuck also comprises guide block 24, as Fig. 5, shown in Figure 6, be evenly equipped with three gathering sills 25 on the described chuck 23, be provided with guide block 24 in each gathering sill 25, be fixed with claw 21 on the described guide block 24, described guide block 24 also is fastenedly connected with slide block 22, described claw 21 is provided with three steps, described transmission mechanism 4 is a hydraulic cylinder, one end of described hydraulic cylinder rotates and is arranged on the support 1, the other end of described hydraulic cylinder is provided with dwang 41, and an end of described dwang 41 is arranged in the rotation slot 32 of platen 3.
Claw 21 is connected with slide block 22 by guide block 24, Push switch during use, hydraulic cylinder pushes away forward, platen 3 is rotated counterclockwise, the straight trough of slide block slot 31 on the platen 3 for being obliquely installed, the slide block 22 that drive is arranged on wherein moves to the direction near the center of circle, because the gathering sill 25 that is provided with on the chuck 23 is the straight troughs along axis, so the athletic meeting of slide block 22 drives guide block 24 fixed thereon and also moves to center of circle direction in gathering sill 25, thereby make the claw 21 that is fixed on the guide block 24 also to the motion of center of circle direction, three claws 21 are all to center of circle direction motion clamping wheel hub; After wheel hub boring is finished, Push switch again, hydraulic cylinder drives platen 3 and clockwise rotates to recovery, makes claw 21 to away from the motion of center of circle direction, unclamps wheel hub.
The above only is a specific embodiment of the utility model, but technical characterictic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
