Description
Technical field
The utility model relates to press machine, particularly relates to the locking device of little table top Dalian rod-type Press Slider.
Background technique
A kind of safety installations of locking sliding block when slide block locking device mainly refers to that people carries out maintenance die in die-filling space, for preventing brake troubles, slide block declines suddenly, damages operator.
Existing sliding block locking device mainly motor-driven ball screw arrangement on market, this structure complex structure, expensive, the installing space of needs is comparatively large, from structure and economic consideration, is not suitable for being arranged on the press machine of little table top.
Model utility content
The utility model, for above problem, provides a kind of structure simple, reduces costs, and improves the slide block locking device of functional reliability.
The technical solution of the utility model is: described slide block connecting ball head screw rod is connected on connecting rod, and the bottom of described connecting rod is provided with cavity, and described ball screw is threaded connection in the cavity of described connecting rod, and the top of described connecting rod is provided with upper beam;
Described locker comprises dunnage, fixed support, spring bolt, oil hydraulic cylinder, switch bracket and a pair proximity switch, described dunnage is fixedly located on described connecting rod, described dunnage is provided with determines hole, described fixed support is located on described upper beam, described oil hydraulic cylinder is fixedly located on described fixed support, described fixed support is provided with towards the described horizontal through hole determining hole, and described spring bolt is actively installed in described through hole, and described spring bolt is fixedly connected on the piston of described oil hydraulic cylinder;
Described a pair proximity switch is connected on described oil hydraulic cylinder by switch bracket.
Described connecting rod is provided with draw-in groove, and described draw-in groove is corresponding described determines hole.
Described draw-in groove is circular arc, and described to determine hole consistent with the cross section of described draw-in groove, and described spring bolt is provided with the clip of circular arc towards described one end of determining hole, and described clip is actively installed in described draw-in groove.
In utility model works, one piece of dunnage installed by the connecting rod that oil hydraulic cylinder is connected with transmission device, at slide block after upper dead center stops, be installed on logical oil on the right side of the oil hydraulic cylinder on the fixed support of upper beam, drive spring bolt action, spring bolt inject dunnage determine in hole, meanwhile, hydraulic cylinder piston inductive proximity switch sender; Now, slide block is in locked position.When slide block want descending before, logical oil on the left of oil hydraulic cylinder, driven plunger moves right, and spring bolt shifts out from dunnage, and proximity switch sender, press normally works.The utility model operation is reliable, provides cost savings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is optimal enforcement mode of the present utility model;
In figure, 1 is connector, and 2 is connecting rods, and 3 is spring bolts, and 4 is fixed supports, and 5 is oil hydraulic cylinders, and 6 is proximity switches, and 7 is dunnages, and 70 is determine hole, and 8 is ball screws, and 9 is upper beams, and 10 is switch brackets, and 11 is draw-in grooves, and 12 is clips.
Embodiment
The utility model as shown in Figure 1-2, described slide block connecting ball head screw rod 8 is connected on connecting rod 2, and the termination of connecting rod 2 is provided with connector 1, and the bottom of described connecting rod 2 is provided with cavity, described ball screw 8 is threaded connection in the cavity of described connecting rod, and the top of described connecting rod 2 is provided with upper beam 9;
Described locker comprises dunnage 7, fixed support 4, spring bolt 3, oil hydraulic cylinder 5, switch bracket 10 and a pair proximity switch 6, described dunnage 7 is fixedly located on described connecting rod 2, described dunnage 7 is provided with determines hole 70, described fixed support 4 is located on described upper beam 9, described oil hydraulic cylinder 5 is fixedly located on described fixed support 4, described fixed support 4 is provided with towards the described horizontal through hole determining hole 70, described spring bolt 3 is actively installed in described through hole, and described spring bolt 3 is fixedly connected on the piston of described oil hydraulic cylinder 5;
Described a pair proximity switch 6 is connected on described oil hydraulic cylinder 5 by switch bracket 10.
Described connecting rod 2 is provided with draw-in groove 11, and described draw-in groove 11 is corresponding described determines hole 70, arranges draw-in groove, spring bolt can be stretched in draw-in groove, realize fixing connecting rod 2.
As shown in Figure 2, described draw-in groove 11 is in circular arc, and described to determine hole 70 consistent with the cross section of described draw-in groove, and described spring bolt 3 is provided with the clip 12 of circular arc towards described one end of determining hole 70, and described clip 12 is actively installed in described draw-in groove 11; Realizing embracing connecting rod by arranging clip, improve the reliability of locking.
At work, after slide block stops to upper dead center, the oil-feed on the right side of oil hydraulic cylinder, promotes piston and is moved to the left the utility model, promotes spring bolt and injects determining in hole in dunnage.Piston proximity switch sender below, now slide block is in locking state, and now press can not start.Operator can enter die-filling space and carry out maintenance work.
Before maintenance terminates normally will to start press, the oil pocket oil-feed on the left of oil hydraulic cylinder, piston driving spring bolt from dunnage determine shift out hole, piston proximity switch action below, press could normally start.
The utility model structure is simple, safe and reliable, low price; Efficiently solve little table-top press and increase slider locking device installing space not, the problem that economic input is large.
