Hole, is provided with the screw rod of full thread in perforation, be installed with handle on screw rod, and it is heavy to be provided with bearing with the corresponding position of handle, at its lower end
Slot structure, the thrust bearing coordinated with handle, at its lower end support is provided with deep gouge structure.But in the actual use of drawbench
Cheng Zhong, there is the phase mutual friction between partial threads and hole wall of perforating and damage, after thread damage, can not ensure to move tune
The scope of agent after changing screw rod, it is necessary to can just be continuing with；Other thrust bearing is arranged in deep gouge structure, and this just needs bearing
Its strength of stability is just can guarantee that with certain thickness, causes bearing to become very heavy, if reduce thickness, bearing can not be ensured
Structural strength, influence overall drawing effect.
The content of the invention
It is an object of the invention to provide a kind of simple in construction, simple to operate, reduction abrasion, strength of stability height, production efficiency
High drawbench.
The technical scheme is that：A kind of drawbench, including bearing, the bearing are provided with and installed and the drawing on bearing
Bar, the pull bar are provided with handle, and the bearing includes bearing plate and is arranged on two supporting legs of bearing plate lower end, the supporting leg
Inwall side be provided with reinforcing plate, the inside of the supporting leg is provided with connecting screw, and the upper end of the connecting screw passes bearing plate,
The connecting screw is provided with adjusting nut, and the inside outer wall of the supporting leg is provided with slide rail, and the slide rail is provided with matches somebody with somebody with it
The hook portion of conjunction, the hook portion include support block and hook, and the top of the bearing plate is provided with annular boss, and the annular boss is set
Put and be in axial direction provided with thrust bearing in the periphery of pull bar, the lower section of the handle, the handle includes cross bar, the pull bar
Through the middle part of cross bar, one end of the cross bar is provided with rocking bar, and the lower end of the pull bar is provided with threaded connection axle sleeve and connection spiral shell
Bolt.
Further, it is fixed with the supporting leg and number of legs identical adjusting nut.
Further, connected between the thrust bearing and handle by race ring.
The present invention has the advantages and positive effects of：Due to using above-mentioned technical proposal, being provided with the inside of supporting leg
Reinforcing plate, the rock-steady structure intensity of supporting leg and bearing plate being enhanced, wherein hook portion can hook the bottom for needing drawing fixing,
Strengthen the dynamics of drawing, strengthen the stability of drawing bearing, at the same thread cnnecting shaft be set on that pull bar lower end periphery encloses it is outer
Screw thread, the work pieces mate of the internal thread set with drawing, preferably draws out workpiece.
