Further, described gear is arranged on the two locating shaft two ends through slide block inside; And the location diaxon passes fixedly backing plate of the inboard gear that is fixed on the slide block; Described inboard gear fixedly is shaped with screwed hole on the backing plate.
Fixedly also be provided with the gear movable pad outside the backing plate in described inboard; Described two locating shafts are supported by the described self-aligning bearing that is installed on the described gear movable pad; Have the mounting hole corresponding with screw on the described inboard gear fixed head on the described gear movable pad;
Also be provided with the gear position limiting baffle plate fixing with slide block at described gear movable pad rear side, described gear position limiting baffle plate has and only draws unthreaded hole and thrust screw; Described gear movable pad is provided with and the screwed hole that only draws unthreaded hole to be complementary;
Described only draw correspondingly to be provided with in unthreaded hole and the thrust screw only draw screw rod and thrust screw rod;
Respectively be welded with fixedly backing plate of tooth bar at fuselage four column medial surfaces, described tooth bar fixedly has along its length direction on the backing plate and has two row screwed holes;
On the tooth bar movable pad, the left and right sides has and the fixing mounting hole one to one of the screw on the backing plate of described tooth bar described tooth bar on the described tooth bar movable pad by screw fastening;
Described tooth bar top and bottom are provided with the postive stop baffle fixing with fuselage, also comprise the stop bit screw that is complementary with described postive stop baffle.
Further, described self-aligning bearing is band square base bearing with spherical outside surface.
Further, described mounting hole is equidistant distribution at the tooth bar movable pad, and spacing is 1/15 ~ 1/8 of tooth bar movable pad length.
The invention has the advantages that: (1) compact conformation is reasonable, can effectively eliminate the synchronous error between four oil cylinders, makes slide block stable; (2) after mechanism moves the long period, synchronous error occurs, be convenient to again eliminate synchronous error by the position relationship of regulating between the parts; So that mechanism has long service life, can guarantee higher synchronization accuracy again simultaneously.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1,2,3,4,5,6 and 7, the present invention includes slide block 1 and fuselage column 2; Four jiaos arrange gear 3 on described slide block 1, are provided with tooth bar 4 formative gears, the rack synchronous mechanism that is complementary with described four gears at described fuselage four columns 2.Described four gears 3 are arranged on two two ends through the locating shaft 5 of slide block inside; And two locating shafts pass fixedly backing plate 6 of the inboard gear that is fixed on the slide block both sides 1; Described inboard gear fixedly is shaped with screwed hole on the backing plate 6; Fixedly also be provided with gear movable pad 7 outside the backing plate 6 in described inboard; Described two locating shafts are supported by the band square base bearing with spherical outside surface 8 that is installed in described gear movable pad 7 sides; Have the mounting hole 7a corresponding with screw on the described inboard gear fixed head 6 on the described gear movable pad 7, gear movable pad 7 and inboard gear fixed head 6 are connected by screw.Also be provided with the gear position limiting baffle plate 9 of fixing with slide block 1 at described gear movable pad 7 rear sides, described gear position limiting baffle plate 9 has and only draws unthreaded hole 9a and thrust screw 9b; Described gear movable pad 7 is provided with and the screwed hole 7b that only draws unthreaded hole 9a to be complementary; Described only draw correspondingly to be provided with in unthreaded hole 9a and the thrust screw 9b only draw screw rod 10 and thrust screw rod 11.Respectively be welded with fixedly backing plate 12 of tooth bar at fuselage four column medial surfaces, described tooth bar fixedly has along its length direction on the backing plate 12 and has two row screwed hole 12a; Described tooth bar 3 by screw fastening on tooth bar movable pad 13, the left and right sides has and the fixing mounting hole 13a one to one of the screw 12a on the backing plate of described tooth bar on the described tooth bar movable pad 13, and described tooth bar fixedly backing plate 12 is connected by screw with the tooth bar movable pad.Described tooth bar 3 tops and bottom are provided with the tooth bar postive stop baffle 14 and 15 fixing with the fuselage column, also comprise the stop bit screw 16 and 17 that is complementary with described tooth bar postive stop baffle 14 and 15.
Described mounting hole 13a is equidistant distribution at tooth bar movable pad 13, and spacing is 1/15 ~ 1/8 of tooth bar movable pad 13 length.
The present invention because of 1 four jiaos of gears 3 that arrange of slide block and the fuselage column 2 tooth bars 4 formation lazy-tongs that mate with gear 3 that arrange, can guarantee the synchronism of 1 four jiaos of slide blocks when specifically using, can effectively eliminate the synchronism that four oil cylinders produce slide block 1.After hydraulic press turns round a period of time, when synchronous error occurring, can reach by the back lash between adjusting gear 3 and the tooth bar 4 purpose of eliminating synchronous error.Adjustment process is as follows: slider of hydraulic press 1 is glided arrive the bottom; unclamp the bolt in four gear removable insole pieces, the 7 mounting hole 7a; at the bottom of slide block, place 1 four jiaos of the high cushion block support slippers of the fourth class; guarantee the depth of parallelism of slide block 1 and table plane; then along gear removable insole pieces 7 mounting hole length directions pulling gear movable pad 7, namely realize adjusting the purpose of gear 3 and tooth bar 4 back lashes.Gear adjust complete after, tighten the screw in the gear movable pad mounting hole 7a, that tightens simultaneously gear position limiting baffle plate 9 only draws screw rod 10 and thrust screw rod 11, prevents adjusted gear 3 front and back plaies.Then regulate the upper-lower position of four tooth bar movable pads, make it and adjust engagement good between the gear of finishing, namely realize adjusting wheel and rack to the initial engagement position.Tooth bar is adjusted the complete while, tightens the screw on the four tooth bar movable pad mounting holes, tightens simultaneously the stop bit screw 16 and 17 of the postive stop baffle of movable pad top and bottom, prevents that tooth bar from moving up and down.
Compact conformation of the present invention is reasonable, can effectively eliminate the synchronous error between four oil cylinders, makes slide block stable; When mechanism synchronous error occurs after the operation long period, be convenient to again eliminate synchronous error by the position relationship of regulating between the parts; So that mechanism has long service life, can guarantee higher synchronization accuracy again simultaneously.
