Abstract
The utility model relates to a cam swing clamping device. The cam swing clamping device comprises a support. An electromagnet is fixed on the support, a movable magnet block is fixed on the support and is fixedly connected with a sliding block which is fixed in a sliding groove of the support, and an upper follow-up bump and a lower follow-up bump are arranged symmetrically on the sliding block. A compression rod for compressing a work-piece is hinged to the support, a return spring fixed on the support is arranged at the middle section of the compression rod, and the first follow-up bump on the sliding block is in contact with the compression end of the compression rod. A fixed cam is arranged on the support, and the cam surface of the cam is in contact with the second follow-up bump on the sliding block. According to the cam swing clamping device, the sliding block is driven by the movable magnet block of the electromagnet to slide in the sliding groove of the support, the two follow-up bumps are arranged symmetrically on the sliding block and are in contact with the compression rod and the fixed cam respectively, so that during the moving of the sliding block, the sliding block extrudes the compression end of the compression rod through the action of the follow-up bumps, and the compression rod is forced to swing with the hinge points serving as the rotation axis to clamp the work-piece.
Description
Technical field
The utility model relates to a kind of clamping tool for machine work, is specifically related to a kind of cam and swings clamping device.
Background technology
Cam is a kind of conventional mechanical part, general cam is applied in mechanism often as a moving component in mechanism, play the effect of transmitting torque, but for some special hold down gags, using separately cam is far from being enough as drive disk assembly, need to design a kind of novel mechanism and realize the swing clamping to workpiece.
Utility model content
The purpose of this utility model is to provide a kind of cam to swing clamping device, is realized and is utilized cam to realize and swing clamping workpiece by cooperatively interacting between mechanism.
For achieving the above object, the technical solution of the utility model is: cam swings clamping device, comprise support, on described support, be fixed with electromagnet, the moving magnetic patch of described electromagnet is fixedly connected with a slide block, described slide block slides and is fixed in the chute of support, is arranged with upper and lower two servo-actuated projections on described slide block; On described support, be hinged with the depression bar of workpiece pressing, the stage casing of described depression bar is provided with the return spring being fixed on support, the compression end in contact of the first servo-actuated projection and depression bar on described slide block; On described support, be also provided with a stationary cam, the cam surface of described stationary cam contacts with the second follower block on slide block.
While adopting technique scheme, moving magnetic patch band movable slider by electromagnet slides in the chute of support, owing to being symmetrical arranged two servo-actuated projections on slide block, and two servo-actuated projections contact with depression bar and stationary cam respectively, therefore in the process that slide block moves, slide block, by the compression end of the effect extruding depression bar of follower block, forces depression bar to swing take pin joint as rotating shaft, and then clamping work pieces.The utility model, by exquisite structural design, using cam as fixed part, has been realized the swing of workpiece has been clamped.
Further, described support vertically arranges, and described electromagnet, slide block, depression bar and stationary cam are arranged on the homonymy of support.By the above-mentioned volume that can reduce whole mechanism that arranges, save space.
Further, on described support, be also provided with the block of restriction slide block shift position.By block is set, can avoid slide block in sliding process because the reason of inertia is deviate from support.
Further, between described slide block and stationary cam, be provided with back-moving spring, one end of described back-moving spring is fixed on slide block, and the other end is fixed on stationary cam.By back-moving spring is set, can change the speed of depression bar in swing process, cause it and realize the variation of speed in swing process.
Further, on institute's support, be also provided with the platform of supporting workpiece.Can further reduce overall volume by platform being integrated on support.
Further, on described support, be also provided with the block of restriction slide block shift position.By block is set, can avoid slide block in sliding process because the reason of inertia is deviate from support.
Further, described block is provided with pressure sensor, and described pressure sensor connects the control device of electromagnet by processor.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation that the utility model cam swings clamping device embodiment.
The specific embodiment
As shown in Figure 1, the utility model cam swings clamping device, has comprised vertical support, is fixed with electromagnet 1 on support, and the moving magnetic patch of electromagnet 1 is fixedly connected with a slide block 2, and slide block 2 slides and is fixed in the chute of support.On slide block 2, be arranged with two integrated servo-actuated projections, two last pulleys that are provided with of projection; On support, be hinged with the depression bar 3 of workpiece pressing 7, the stage casing of depression bar 3 is provided with the return spring 31 being fixed on support, the compression end in contact of the first servo-actuated projection 21 and depression bar 3 on slide block 2; On support, be also provided with a stationary cam 4, the cam surface of this stationary cam 4 contacts with the second follower block 22 on slide block 2.On support, be also provided with the block 5 of restriction slide block 2 shift positions.By block 5 is set, can avoid slide block 2 in sliding process because the reason of inertia is deviate from support.Block 5 is provided with pressure sensor, and described pressure sensor connects the control device of electromagnet 1 by processor.Between slide block 2 and stationary cam 4, back-moving spring 6 is installed, one end of back-moving spring 6 is fixed on slide block 2, and the other end is fixed on stationary cam 4.By back-moving spring 6 is set, can change the speed of depression bar 3 in swing process, cause it and realize the variation of speed in swing process.The also integrated platform 71 of supporting workpiece 7 on support.
When operation, moving magnetic patch band movable slider 2 by electromagnet 1 slides in the chute of support, owing to being symmetrical arranged two servo-actuated projections on slide block 2, and two servo-actuated projections contact with depression bar 3 and stationary cam 4 respectively, therefore in the process that slide block 2 moves, slide block 2, by the compression end of the effect extruding depression bar 3 of follower block, forces depression bar 3 to swing take pin joint as rotating shaft, and then clamping work pieces 7.The utility model, by exquisite structural design, using cam as fixed part, has been realized the swing of workpiece 7 has been clamped.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
