As the patent CN202344298U of bulletin on July 25th, 2012, mentioned a kind of hydraulically operated fixture, comprise holder, movable pressure plate and hydraulic lifting arm, on described holder, be provided with elevating lever connecting hole, the diameter of the diameter of described elevating lever connecting hole and described hydraulic lifting arm adapts, described holder is flexibly connected with described hydraulic lifting arm, described hydraulic lifting arm is fixedly connected with described movable pressure plate, described fixture also comprises gag lever post, and described gag lever post is connected with described holder.This apparatus structure has limited the top that hydraulic mechanism must be positioned at fixture, and holder also must be fixed on the top of being pressed workpiece, for frame, has particular requirement, has limited the scope of application of fixture, and therefore above-mentioned fixture can not be adapted in the clamping of all workpiece.
Summary of the invention
The purpose of this utility model is fixture is had to the problem of different requirements for the different clip positions of different product workpiece, and a kind of pneumatic positioning fixture that adopts alignment pin location is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of pneumatic positioning fixture, comprise stand, cylinder, stand is provided with bearing, on bearing, be fixed with U-shaped cylinder block, U-shaped cylinder block has a base plate and is positioned at front side board and the back side panel of base plate dual-side, base plate and bearing are fixed, back side panel outside is fixed with cylinder, the pistons end of cylinder is connected with alignment pin by the axis of guide, alignment pin extend out to front side board outside, be provided with in guiding collar week evagination for abutting to the limited step of front side board medial surface.Adopt split single seat, utilize fixedly cylinder of back side panel, use front side board to lead with spacing, both guaranteed the accuracy of alignment pin location, limited again the flexible scope of cylinder piston.
As preferably, axis of guide rear end adopts and is threaded with piston.
As preferably, it is inner that alignment pin rear end is embedded axis of guide front end, and be provided with for holding out against the screw hole of alignment pin in the side of axis of guide front end.
As preferably, described front side board and back side panel are provided with corresponding through hole, and piston is through back side panel through hole, and the axis of guide is through the through hole of front side board, and are provided with fairlead in the through hole of front side board.
As preferably, the be provided with screw hole that hold out against fixed guide cover vertical with through hole on described front side board.
As preferably, the thickness of described front side board is greater than back side panel.Front side board thickness is large, and guide section length is long, is that alignment pin telescopic process can keep stablizing.
As preferably, the setting of lying on one's side of described U-shaped cylinder block, base plate is fixed on the side of bearing, and base plate and front side board, back side panel are positioned at same level.
The utility model adopts U-shaped cylinder block, and before and after utilizing, the distance of side plate, is leading apart from cylinder one fragment position place, has guaranteed that the position location of alignment pin is stable; Utilize front side board as limiting plate simultaneously, coordinate with the limited step of fairlead and can carry out spacing to the flexible amplitude of alignment pin.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the utility model plan structure schematic diagram.
To be that this use is novel be installed on the structural representation on stand to Fig. 3 together with other fixtures.
In figure: 1. stand, 2. cylinder, 3.U type cylinder block, 31. base plates, 32. back side panels, 33. front side boards, 4. fairlead, the 5. axis of guide, 51. limited steps, 6. alignment pin, 7. holds out against screw, 8. bearing, 9. piston.
The specific embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is further illustrated.
Embodiment: a kind of pneumatic positioning fixture, as shown in Figure 1, Figure 3.This device is arranged on plane stand 1 and uses.Plane stand 1 is provided with L shaped bearing 8, is provided with leg-of-mutton reinforcement gusset between bearing 8 sides and bottom surface.The another side of bearing is fixed with U-shaped cylinder block 3.U-shaped cylinder block has a base plate 31 and front side board 33 and back side panel 32, and U-shaped cylinder block is horizontal setting, and base plate 31 and front side board 33 and back side panel 32 are positioned at same level, and the side of base plate and bearing 8 is fixed.The lateral surface of back side panel 32 is fixed with cylinder 2, and back side panel is provided with corresponding through hole with front side board.The piston 9 of cylinder 2 is threaded fixing through back side panel through hole with the rear end of the axis of guide 5, the axis of guide 5 connects alignment pin 51 through after the through hole of front side board, alignment pin rear end embeds the front end of the axis of guide, axis of guide front end side is provided with the screw that holds out against for securing dowel, the rear end annular protrusion of the axis of guide 5 forms limited step 51, limited step external diameter is greater than the aperture of front side board through hole, makes limited step can be stuck in front side board medial surface spacing.In the through hole of front side board 33, be provided with fairlead 4, and on front side board, be provided with the screw that holds out against of vertical and through hole.The thickness of front side board is greater than the thickness of back side panel, and both Thickness Ratios are 3:1.
