On described active compressing support, be provided with active lateral hold-down head, on described passive compressing support, be provided with passive horizontal hold-down head, and be also provided with rotary vertically to hydraulic pressure arm on described active compressing support and passive compressing support;
In described stage support, be also provided with and promote the hydraulic drive mechanism that initiatively compressing support slides along straight guide.
Further, described stage support is also connected with passive compressing support by straight guide fixed thereon, is also provided with the leading screw of passive compressing support position on straight guide, location in described stage support.
Further, on described floor-supporting piece, be provided with the bar hole parallel with straight guide, floor-supporting piece is by being arranged on being bolted in stage support in bar hole.
Further, on described floor-supporting piece, be provided with the U-lag parallel with straight guide, in described U-lag, be provided with the cushion block being slidably matched with it, on the sidewall of described U-lag, be provided with some screwed holes.
Further, described railway carriage floor welded frock also comprises hydraulic control system, and described hydraulic control system comprises to hydraulic drive mechanism and rotary vertically provides Hydraulic Station and the Hydraulic Station controller of hydraulic oil to hydraulic pressure arm.
Beneficial effect of the present invention:
1, railway carriage floor welded frock of the present invention, its to floor carry out the active lateral hold-down head that laterally compresses and to floor carry out the vertical rotary vertically compressing to the action of hydraulic pressure arm by HYDRAULIC CONTROL SYSTEM, compress and loosen automatically and complete, clamping is consuming time short, can large increase operating efficiency.
2, railway carriage floor welded frock of the present invention, under HYDRAULIC CONTROL SYSTEM, the horizontal thrust that each active lateral hold-down head applies floor is identical, the vertical pressure that each rotary vertically applies floor to hydraulic pressure arm is also identical, thereby can reduce floor stress deformation amount, improve welding quality.
3, railway carriage floor welded frock of the present invention, the position of its active compressing support, passive compressing support and floor-supporting piece is adjustable, thereby makes the floor compartment of this frock energy clamping different size, and adaptability is good, can reduce frock cost.
Accompanying drawing explanation
Fig. 1 is railway carriage floor welded frock top view of the present invention;
Fig. 2 is that Fig. 1 is along the cutaway view of A-A;
Fig. 3 is the zoomed-in view of P portion in Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment railway carriage floor welded frock, comprise stage support 1, in stage support 1, be provided with the some groups of straight guides that are parallel to each other 2, on described straight guide 2, be provided with the active compressing support 3 being slidably matched with its single-degree-of-freedom, in described stage support 1, be also provided with passive compressing support 4, between described active compressing support 3 and passive compressing support 4, be provided with floor-supporting piece 5;
On described active compressing support 3, be provided with active lateral hold-down head 6, on described passive compressing support 4, be provided with passive horizontal hold-down head 7, and be also provided with rotary vertically to hydraulic pressure arm 8 on described active compressing support 3 and passive compressing support 4;
In described stage support 1, be also provided with and promote the hydraulic drive mechanism 9 that initiatively compressing support 3 slides along straight guide 2, in the present embodiment, hydraulic drive mechanism 9 comprises hydraulic cylinder 901 and is fixed on the hydraulic cylinder seat 902 in stage support 1, and the cylinder body of hydraulic cylinder 901 and piston rod are hinged on respectively on hydraulic cylinder seat 902 and active compressing support 3.
During welding, floor compartment is placed on floor-supporting piece 5, hydraulic drive mechanism 9 promotes initiatively compressing support 3 and moves along straight guide 2 under HYDRAULIC CONTROL SYSTEM, initiatively the active lateral hold-down head 6 on compressing support 3 just promotes that floor compartment moves and floor compartment is held out against on passive horizontal hold-down head 7, then HYDRAULIC CONTROL SYSTEM is controlled rotary vertically again to 8 rotations of hydraulic pressure arm to compressing station, and floor compartment is vertically pressed on to floor-supporting piece 5.
