Description
Technical field
The utility model relates to part processing and uses device, but refers to particularly a kind of band revolution self clamping device.
Background technology
Part is located accurately and clamped is the prerequisite that processes qualified parts, and the requirement of working (machining) efficiency is more and more higher, and same station becomes more and more general by a plurality of technique contents of panoramic table revolution processing.In the prior art, when part need turn round, owing to existing clamp pressing spare can't rotate with part, thereby revolution and clamping function can not be realized, part processing precision and project construction efficient can't be guaranteed.
Summary of the invention
The purpose of this utility model is the deficiency that exists in order to overcome the above-mentioned background technology, but proposes a kind of band revolution self clamping device.
For achieving the above object, but a kind of band revolution self clamping device that the utility model is designed, comprise clamping cylinder, the compressor arm coaxial with clamping cylinder, described compressor arm is positioned at workbench, the compressor arm bottom is provided with keeper, it is characterized in that: it also comprises self-lock rod, self-locking oil cylinder, described self-lock rod is fixedly connected with piston rod on the described self-locking oil cylinder, described compressor arm is made of fixed bar and the swingle of coaxial arrangement, described fixed bar is positioned at the upper end, described swingle is positioned at the lower end, described fixed bar and described swingle are flexibly connected by connector, radially be provided with through hole on the described fixed bar, described self-lock rod can pass described through hole, and the mating surface between described self-lock rod lower surface and the described through hole corresponding surface is the inclined-plane.
The inclined-plane of described through hole is horizontal by 15 ° of angles.
Described connector comprises transit joint, flange cover, return spring, described transit joint is connected with fixed bar, described flange cover is connected with swingle, supported by sliding bearing, thrust ball bearing between described transit joint and the described flange cover, described return spring is between described transit joint and described flange cover, and described return spring top is provided with spacing steel ball.
Described keeper eccentric setting is in the swingle lower end, and described keeper is provided with compressing member and with the limited block of part rotation.
The utility model has the advantage of: the lower end of fixed bar is made as swingle, during work, swingle can rotate with part, when forwarding the position that needs processing to, clamping cylinder is exerted pressure, and keeper is fixedly clamped part, the self-locking oil cylinder piston rod stretches out subsequently, the wedge type piece that promotes the self-lock rod front end inserts through hole, and compressor arm is fixed, and has realized the function that self-locking clamps.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the local enlarged diagram of connector.
The specific embodiment
Below in conjunction with accompanying drawing and implementation the utility model is described in further detail.
But a kind of band revolution self clamping device shown in the figure, comprise clamping cylinder 1, the compressor arm 2 coaxial with clamping cylinder 1, compressor arm 2 is positioned at workbench 8, compressor arm 2 bottoms are provided with keeper 3, keeper 3 eccentric settings are in swingle 6 lower ends, the limited block 11 that described keeper 3 is provided with compressing member 12 and rotates with part, it also comprises self-lock rod 4, self-locking oil cylinder 10, self-lock rod 4 is fixedly connected with piston rod on the self-locking oil cylinder 10, compressor arm 2 is made of fixed bar 5 and the swingle 6 of coaxial arrangement, fixed bar 5 is positioned at the upper end, swingle 6 is positioned at the lower end, fixed bar 5 is flexibly connected by connector 7 with swingle 6, radially be provided with through hole 9 on the fixed bar 5, self-lock rod 4 can pass through hole 9, mating surface between self-lock rod 4 lower surfaces and through hole 9 corresponding surfaces is the inclined-plane, the inclined-plane is horizontal by 15 ° of angles, connector 7 comprises transit joint 7a, flange cover 7b, return spring 7c, crossing joint 7a is connected with fixed bar 5, flange cover 7b is connected with swingle 6, transit joint 7a and flange overlap between the 7b by sliding bearing 7d, thrust ball bearing 7e supports, return spring 7c is between transit joint 7a and flange cover 7b, and return spring 7c top is provided with spacing steel ball 7f.
During work, self-locking oil cylinder 10 and clamping cylinder 1 are all in position, part is after panoramic table is accurately located, the piston rod of clamping cylinder 1 stretches out, compressing member 12 contact parts but do not clamp, do not exert pressure (this action is realized by the middle bit function of three position four-way electromagnetic valve), when part turns round with panoramic table, limited block 11 moves with part, and compressing member 12 also can rotate thereupon, when forwarding the position that needs processing to, clamping cylinder 1 is exerted pressure, keeper 3 is fixedly clamped part, and the piston rod of self-locking oil cylinder 10 stretches out subsequently, and the wedge type piece that promotes self-lock rod 4 front ends inserts through hole 9, make compressor arm 2 fixing, realized the function that self-locking clamps; When need move to other Working position, repeat a circulation, when part needs reposition, on the contrary action.
