Abstract
The utility model relates to a mechanical die setting height locking device for a press machine in the technical field of press machines, which comprises a connecting rod and a ball screw. The connecting rod is provided with internal threads meshed with external threads at the upper end of the ball screw, the ball screw is provided with a locking sleeve below the connecting rod, internal threads of the locking sleeve are meshed with external threads of the ball screw, the locking sleeve is tightly abutted to the lower end of the connecting rod, a pressure cap pressing the locking sleeve onto the connecting rod is sleeved on the ball screw, the pressure cap and the connecting rod are connected via a screw, and the pitches of the internal threads of the connecting rod are unequal to those of the internal threads of the locking sleeve. Two threaded sections with unequal pitches are arranged on the ball screw so that the ball screw cannot rotate after the pressure cap presses the locking sleeve to the connecting rod tightly. Compared with the prior art, the mechanical die setting height locking device is smart in conception, simple in structure, convenient in processing and assembly, high in bottom dead center precision and difficult to be loosen, precision of the mechanical die setting height locking device can be maintained for a long period of time, and reliability of the press machine can be improved.
Description
Technical field
The utility model relates to a kind of locking device of forcing press height of packing compact, belongs to the press technologies field.
Background technology
At present, traditional height of packing compact mechanical locking device mainly includes connecting rod and ball screw, being provided with internal thread in the connecting rod is meshed with the external screw thread of ball screw upper end, can be connecting rod and ball screw is locked by locking nut, in the actual use, it is not firm locking to occur through regular meeting; High velocity ram machine particularly, because of upper frequency impacts and lathe shakes, ball screw is easier to be rotated, and causes and the variation of bottom dead centre influence machine finish.
The utility model content
The purpose of this utility model is at traditional height of packing compact mechanical locking device poor reliability, can not effectively guarantee the technical problem of slide block bottom dead centre precision, the forcing press height of packing compact mechanical locking device that provide a kind of easy processing, easily assemble, precision stability is good.
The utility model is to solve above-mentioned technical problem by following technical solution: a kind of forcing press height of packing compact mechanical locking device, comprise connecting rod and ball screw, being provided with internal thread in the connecting rod is meshed with the external screw thread of ball screw upper end, on ball screw and be positioned at the connecting rod downside and be provided with lock sleeve, internal thread on the lock sleeve is meshed with external screw thread on the ball screw, lock sleeve abuts in the connecting rod lower end, be set with on the ball screw lock sleeve is pressed on gland on the connecting rod, be connected through screw between described gland and the connecting rod; The internal thread on the connecting rod and the pitch of the internal thread on the lock sleeve are unequal.
Height of packing compact mechanical locking device of the present utility model, the setting of two sections screw threads by the decreasing worm-pitch on ball screw makes that ball screw can not rotate after gland compresses lock sleeve and connecting rod, compared with prior art, this device is skillfully constructed, and is simple in structure clear, processing, easy to assembly, bottom dead centre precision height, and can keep its high accuracy for a long time, be difficult for becoming flexible, can improve the reliability of forcing press.
As further improvement of the utility model, the internal thread on the described connecting rod is the dextrorotation trapezoidal thread, and the internal thread on the lock sleeve is left-handed fine thread.Trapezoidal thread has the strong advantage of bearing capacity, and after gland compressed, the lock sleeve upper-lower position was fixed, thereby prevents the ball screw rotation, and can reduce thread pitch by the rotational lock cover.
Regulate for convenient, can adjustment hole be set in the side of lock sleeve.Unclamp gland, in adjustment hole, insert adjustment means, rotatable locking cover makes lock sleeve and connecting rod separately, thereby can be by rotating ball screw, change the axial location relation between ball screw and the connecting rod, reach the purpose that height of packing compact is regulated, after the adjusting, rotatable locking cover, make it abut in interlinking lever end once more, then with gland with screw in compression.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 connecting rod, 2 glands, 3 lock sleeves, 4 ball screws, 5 screws, 6 adjustment holes.
The specific embodiment
Further specify utility model below in conjunction with drawings and Examples:
As shown in Figure 1, be a kind of forcing press height of packing compact mechanical locking device, comprise connecting rod 1 and ball screw 4, being provided with internal thread in the connecting rod 1 is meshed with the external screw thread of ball screw 4 upper ends, on ball screw 4 and be positioned at connecting rod 1 downside and be provided with lock sleeve 3, the internal thread on the lock sleeve 3 is meshed with external screw thread on the ball screw 4, and lock sleeve 3 abuts in connecting rod 1 lower end, be set with on the ball screw 4 lock sleeve 3 is pressed on gland 2 on the connecting rod 1, be connected through screw 5 between gland 2 and the connecting rod 1; The pitch of the internal thread on internal thread on the connecting rod 1 and the lock sleeve 3 is unequal.
Internal thread on the preferably described connecting rod 1 is the dextrorotation trapezoidal thread, and its bearing capacity is good, and the internal thread on the lock sleeve 3 is left-handed fine thread, so that do small adjusting; Regulate for convenient, adjustment hole 6 can be set in the side of regulating sleeve.
When adjusting height of packing compact, unclamp gland 2, in adjustment hole 6, insert adjustment means, rotatable locking cover 3, make lock sleeve 3 and connecting rod 1 separately, thereby can change the axial location relation between ball screw 4 and the connecting rod 1 by rotating ball screw 4, reach the purpose that height of packing compact is regulated, after the adjusting, backward rotation lock sleeve 3 makes it abut in connecting rod 1 end once more, gland 2 is compressed with screw 5 to get final product then.
Claims (3)
