As shown in fig. 1-3, the utility model relates to an automatic hydraulic press length measurement and reverse thrust mechanism, including support body 1 and controller, support body 1 adopts tubular product or type pole welding to form. Silo 2 is installed at 1 top of support body, 2 top surfaces of silo are the arc, are convenient for lead spacing to the steel pipe. The utility model discloses a length measuring device, including silo 2, support body 1 at silo 2 both ends is last to weld length measuring mounting panel 3 respectively and to push away material mounting panel 4, the slide 5 that bolt fastening and silo 2 are parallel on the length measuring mounting panel 3, slide 5 slides and sets up push rod 6, push rod 6 only can slide in slide 5, and can't rotate around slide 5 axes. The tail end of the push rod 6 is provided with a rack 7, one side of the slide way 5 is fixed with a servo motor 8 through a bolt, a motor shaft of the servo motor 8 is provided with a driving gear 9 meshed with the rack 7, the push rod 6 is driven through the servo motor, and therefore the telescopic action of the push rod 6 is completed. A length measuring encoder 10 matched with the servo motor 8 is fixed on one side of the servo motor through bolts, a driven gear meshed with the driving gear 9 is installed on a rotating shaft of the length measuring encoder 10, accordingly, the servo motor 8 drives the length measuring encoder 10, and the stroke of the push rod 6 is detected through the length measuring encoder 10. Bolt installation pushes away material hydro-cylinder 11 on pushing away material mounting panel 4, it is coaxial with push rod 6 to push away material hydro-cylinder 11, the piston rod tip installation stub bar 12 that pushes away material hydro-cylinder 11, silo 2 is close to and pushes away 4 one ends of material mounting panel and sets up first photoelectric sensor 13, servo motor 8, length measuring encoder 10, push away material hydro-cylinder 11 and first photoelectric sensor 13 all are connected with the controller electricity. When the device is used, a steel pipe is firstly placed into the trough 2 through the lifting appliance, the steel pipe automatically slides to the bottom of the trough 2 in the arc-shaped trough 2, one end of the steel pipe is required to be ensured to exceed the first photoelectric sensor 13 when the steel pipe is placed into the trough, then the controller controls the material pushing oil cylinder 11 to push the steel pipe, when the photoelectric sensor just crosses the detection of the first photoelectric sensor, the first photoelectric sensor transmits a signal to the controller, and the controller controls the material pushing oil cylinder to stop pushing material and recover. And meanwhile, the controller controls the servo motor 8 to act to drive the push rod 6 to stretch out, after the push rod pushes the steel pipe, the other end of the steel pipe passes through the first photoelectric sensor 13 again, at the moment, the first photoelectric sensor transmits a signal to the controller, the controller records the stroke of the length measuring encoder 10 at the same time, the controller calculates the distance between the first photoelectric sensor and the initial position of the push rod and subtracts the stroke of the length measuring encoder 10, and the length size of the steel pipe is obtained.
