Please refer to Fig. 1 to Fig. 3, the utility model drawbench 100 comprises a rotary handle 10, a drawing part 20, a clutch shaft bearing 30, one second bearing 40 and a pedestal 50.

Rotary handle 10 comprises leader 12.Handle 12 is gear-like, caves in and form depression 14 in the top, marginating compartment some grooves 120 are arranged.The cave in center of 14 bottoms is run through and is formed a through hole 140.The bottom of handle 12 vertically is convexly equipped with a conduit 16.The center of circle of through hole 140 is positioned on the axis of conduit 16.The inwall of conduit 16 is provided with screw thread 160.In other embodiments, can also in the groove 120 of two symmetries, a torsion bar be set respectively, use this that torsion bar is convenient to rotate rotary handle 10.

Drawing part 20 comprises a screw rod 22.Screw rod 22 1 ends are provided with a bizet 24 with interior hex slot 242.

Clutch shaft bearing 30 is a zanjon bearing, comprises that two are provided with at interval and concentric outer shaft 32, internal axle sleeve 34 and be arranged on plurality of balls 36 between the inside and outside

axle sleeve

32,34.

Second bearing 40 is a thrust bearing, comprises Upper shaft sleeve 42, the Lower shaft sleeve 44 that is oppositely arranged and is arranged on ball 46 between two axle sleeves 42.

Pedestal 50 is cylindric, and the middle part of running through its end face and bottom surface forms a through hole 52.Cave in and form an avoiding area 54 in the bottom of pedestal 50.Cave in and form a receiving space in the top, this receiving space comprises first resettlement section 56 of accommodating clutch shaft bearing 30 and is positioned at second resettlement section 58 of accommodating second bearing 40 of the bottom of first resettlement section 56.Form a stage portion 59 between first resettlement section 56 and second resettlement section 58.Stage portion 59 is provided with a through hole 590 that runs through pedestal 50.

Please continue to consult Fig. 1 and Fig. 3, during assembling, successively second bearing 40 is positioned in second resettlement section 58 of pedestal 50, clutch shaft bearing 30 is positioned in first resettlement section 56, fixedly connected by interference fit between the outer shaft 32 of clutch shaft bearing 30 and the inwall of first resettlement section 56, and place on the stage portion 59.The conduit 16 of rotary handle 10 insert clutch shaft bearings 30 internal axle sleeve 34 and and internal axle sleeve 34 between be connected and fixed by interference fit, the end of conduit 16 is pressed on the Upper shaft sleeve 42 of second bearing 40.The bizet 24 of rotation drawing part 20, the screw rod 22 of drawing part 20 passes from the through hole 140 of rotary handle 10, and spiral passes conduit 16, passes clutch shaft bearing 30, second bearing 40 then successively, and the through hole 52 from pedestal 50 passes at last.During dismounting, after drawing part 20 rotated, pass through hole 590 by a push rod (figure does not show) rotary handle 10, clutch shaft bearing 30 and second bearing 40 are ejected in pedestal 50.

See also Fig. 4, the utility model drawbench 100 can be used for drawing one and treats the drawing workpiece, and this workpiece to be pulled out comprises a fixed head 60 and a movable part 70.Drawbench 100 is used for drawing movable part 70 and moves to a fixed head 60.Fixed head 60 is provided with a perforation.Be provided with a sleeve 80 between fixed head 60 and the movable part 70, sleeve 80 is arranged with an elastic device 90, and elastic device 90 is a spring.Be provided with screw thread 82 in the sleeve 80, sleeve 80 is fixed in movable part 70 and wears the elastic device movable perforation that is contained in fixed head 60 after 90s.The two ends of elastic device 90 contact fixed head 60 and movable part 70 respectively.

Drawbench 100 is located on the fixed head 60, the avoiding area 54 of pedestal 50 bottoms covers on the sleeve 80, and the screw rod 22 of drawing part 20 rotates the bizet 24 of drawing part 20 over against sleeve 80, make screw rod 22 lock in the sleeve 80, screw rod 22 locks with the screw thread 82 of sleeve 80.The handle 12 of turn this moment rotary handle 10, rotary handle 10 relative drawing part 20 rotations, make drawing part 20 rotations upwards by screw thread 160, because drawing part 20 is fixing with sleeve 80, sleeve 80 is fixing with fixture 70, this moment, the compressible elastomeric device 90, drive sleeve 80 fixture 70 is moved to the direction near fixed head 60.The handle 12 of opposite spin rotary handle 10 makes movable part 70 move downward, and this principle is identical with the principle that movable part 70 moves upward, and is not giving unnecessary details at this.The avoiding area 54 of pedestal 50 is used for that sleeve 80 is kept away the position and prevents to interfere.

The elastic force that the utility model drawbench 100 can overcome elastic device 90 convenient and strength-savingly is regulated the position of movable part 70, so that movable part 70 moves up and down.
