Abstract
The utility model discloses a novel connection device of a press connection rod and a ball screw rod. A positioning flange is fixedly mounted on a lower port part of the connection rod by a bolt; the ball screw rod is mounted in a screwed hole of the connection rod from a centre hole of the positioning flange; the part of the ball screw rod close to the ball part is made into a ball smooth cylinder; and the size of the ball smooth cylinder is the same as the free size of the centre of the positioning flange. As the positioning flange can forcibly ensure that the axle centre of the ball screw rod is concentric with the axle centre of the positioning flange, the defects that threads are deformed or even damaged, the threads between the connection rod and the ball screw rod are not easy to adjust and the equipment is damaged due to excessive local stress of the threads caused by stress unbalance between the connection rod and the ball screw rod are avoided.
Description
Technical field
The utility model relates to the jockey of a kind of press connecting rod and spheroid screw mandrel, and the jockey of particularly a kind of novel press machine connection rod and spheroid screw mandrel belongs to the metal forming machinery technical field.
Background technology
Connecting rod and ball screw are the critical function parts of forcing press, and they cooperate transmission pressure by both internal and external threads, simultaneously by the adjusting that realizes by the controllability between both screw threads forcing press operating mechanism.At present, the screw thread that usually takes place in the use of reality between the two is difficult to regulate, even the phenomenon that thread damage takes place takes place, cause the main cause that this phenomenon takes place to be: connecting rod and the bindiny mechanism of ball screw directly are connected by both screw thread, this method of attachment is not too reasonable, because connecting rod and the ball screw transmission of pressure at work always do not carry out along both axis, so cause the stressed generation unbalance loading between the screw thread, local pressure is excessive, thereby causes deforming between screw thread even damaging.
Summary of the invention
The purpose of this utility model is: the jockey that a kind of novel press machine connection rod and spheroid screw mandrel are provided, overcome existing press connecting rod and ball screw owing to adopting direct thread connecting mode to exist: since connecting rod and ball screw at work the transmission of pressure always do not carry out along both axis, cause the stressed generation unbalance loading between the screw thread easily, local pressure is excessive, causes the defective that deforms between screw thread even damage; And connecting rod that causes therefrom and the difficult adjusting of the screw thread between the ball screw, or the accident of device damage.
Solving the technical scheme that its technical problem adopts is: the jockey of a kind of novel press machine connection rod and spheroid screw mandrel, it is the lower end oral area that is fixed and is installed in connecting rod with bolt by locating flange, is installed to ball screw in the screwed hole of connecting rod from the mider hole of locating flange; In the part of ball screw near bulb, make bulb light cylinder, the size of bulb light cylinder is identical with the free size at the center of locating flange.
Beneficial effect: because locating flange can guarantee forcibly that the axle center of ball screw is concentric with the axle center of himself, so avoided between connecting rod and the ball screw because the stressed screw thread local pressure that unbalance loading caused is excessive causes: the defective that deforms between screw thread even damage, and connecting rod that causes thus and the difficult adjusting of the screw thread between the ball screw, or the defective of device damage accident.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Shown in the figure: 1, connecting rod; 2, ball screw; 3, locating flange; 4, bolt; 5, bulb light cylinder.
The specific embodiment
Lower end oral area with locating flange 3 usefulness bolts 4 are fixed and are installed in connecting rod 1 is installed to ball screw 2 in the screwed hole of connecting rod 1 from the mider hole of locating flange 3; In the part of ball screw 2 near bulb a, make bulb light cylinder 5, the size d1 of bulb light cylinder 5 is identical with the free size of the center b of locating flange 3.
Claims (2)
1. the jockey of novel press machine connection rod and spheroid screw mandrel, it is characterized in that: locating flange (3) is fixedly mounted on the lower end oral area of connecting rod (1) with bolt (4), in the screwed hole of the connecting rod (1) that ball screw (2) is installed to from the mider hole of locating flange (3).
2. according to the jockey of claims 1 described a kind of novel press machine connection rod and spheroid screw mandrel, it is characterized in that: in the part of ball screw (2) near bulb (a), make bulb light cylinder (5), the size d1 of bulb light cylinder (5) is identical with the free size of the centre bore (b) of locating flange (3).
