Abstract
The invention provides a fast positioning device of a core rod. The fast positioning device can be used for previously and accurately conveying the core rod to a clamping groove of a limiting rack and shortening the time of the integral process at the same time. The fast positioning device comprises a chain conveyer, a baffle plate and a conveying roller way, wherein the baffle plate is fixedly arranged on one end head of the chain conveyer; the conveying roller way is arranged on a base corresponding to the position of the clamping groove of the limiting rack; the base is provided with at least two limiting clamping jaws for realizing grasping; the middle parts of the limiting clamping jaws are respectively sleeved on a main shaft; the tail parts of the limiting clamping jaws are respectively and rotatablely connected with a piston rod of an air cylinder; and a proximity switch is connected with the air cylinder in an electronic control way.
Description
Technical field
The present invention relates to the positioner of the interior plug of pipe mill in the seamless steel tube production chain, be specially a kind of plug fast-positioning device.
Background technology
In seamless steel tube production chain, the plug that is used to process steel pipe must insert in the rolled steel tube tube chamber in advance, and this process is called " pre-aligned ".At present existing pre-aligned be plug to be sent in the rolled steel tube tube chamber by chain-linked conveyer, it makes plug be positioned at control tooth clamp bar slot place by the baffle plate that is contained in the chain-linked conveyer termination, plug ploughs under in the control tooth clamp bar slot by Hui Sitong mechanism.For controlling the position that baffle plate stops; installed near gauge tap; but this structure exists when chain-linked conveyer carries plug to arrive near control tooth clamp bar slot place; baffle plate does not make plug stop at assigned address fully; it is because action of inertia continues preshoot; therefore can't receive the particular location that accurate signal is judged plug near gauge tap; and this structural requirement chain-linked conveyer carries the speed of plug very slow; could realize that plug arrives limiting tooth clamp bar slot place in advance, so whole process length consuming time.
Summary of the invention
There is above-mentioned defective at existing mandrel positioning device, the invention provides the plug fast-positioning device, can make plug accurately be transported to control tooth clamp bar slot place in advance, can shorten the time of whole process simultaneously.
Its technical scheme is such: it comprises chain-linked conveyer, baffle plate, rollgang, described baffle plate is fixedly mounted on a termination of described chain-linked conveyer, described rollgang is installed on base, the draw-in groove position of corresponding restraint tooth bar, described base is provided with at least two spacing claws of realizing grasping, the middle part of described claw is set with in main shaft, and the afterbody of described claw is rotationally connected with the piston rod of cylinder respectively, electricly connects near switch and described cylinder.
The present invention adopts after the said structure, when plug is transported to the setting stop position by chain-linked conveyer, baffle plate on the chain-linked conveyer promotes plug, plug is by the inertia segment distance that moves ahead, start cylinder this moment and drive the main shaft rotation, main shaft drives claw again and advances plug and catch plug caudal peduncle edge, forces to make and the coincidence parallel with control tooth clamp bar slot position of plug caudal peduncle position, and plug drives and can plough under exactly in the control tooth clamp bar slot by roller-way.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the different size plug is at position view of the present invention;
The exceed structural representation in carry-over bar draw-in groove interval of Fig. 3.
The specific embodiment
See Fig. 1, figure, Fig. 3, the present invention includes chain-linked conveyer 1, baffle plate 2, rollgang 8, baffle plate 2 is fixedly mounted on a termination of chain-linked conveyer 1, rollgang 8 is installed on base 9, the draw-in groove position of corresponding restraint tooth bar, base 9 is provided with at least two spacing claws of realizing grasping 4, and the middle part of claw 4 is set with in main shaft 5, and the afterbody of claw 4 is rotationally connected with the piston rod of cylinder 6 respectively.Decide according to the position that plug caudal peduncle 3 will stop installation site near switch 10, electricly connects near switch 10 and cylinder 6.Below in conjunction with accompanying drawing the course of work of the present invention is described: chain-linked conveyer 1 transmission, driving baffle plate 2 moves together, stop, baffle plate 2 promotes plug, plug is by the inertia segment distance that moves ahead, start cylinder 6 near switch 10 and drive the swing of claw 4 rear portions, make the bump head of claw 4 front portions advance plug and catch plug caudal peduncle 3 edges, the action of cylinder 6 drives claw 4 and rotates grabbing and putting of cooperating between the realization claw, pressure makes plug caudal peduncle 3 positions parallel with control tooth clamp bar slot 7 interval positions, the installation site in control tooth clamp bar slot 7 intervals, direction is parallel with the plug fast-positioning device, see Fig. 2, its the default coincidence of the plug of different size is also different in the position in control tooth clamp bar slot 7 intervals, can finish the plug arrival of different size and its caudal peduncle is overlapped in control tooth clamp bar slot 7 intervals of different size size by the design of restraint program and locate, roller-way 8 is fixedly mounted on the base 9, and plug can plough under in the control tooth clamp bar slot 7 exactly by the drive of roller-way 8.
