In view of this, the object of this invention is to provide a kind of skirt plate of railway vehicle grid welding rotary fixture, it can realize welding of upper strata grille strip and lower floor's grille strip and skirtboard frame in same frock, raising welding job efficiency that can be very large, and ensures welding quality.The concrete scheme of skirt plate of railway vehicle grid welding rotary fixture of the present invention is:
Skirt plate of railway vehicle grid welding rotary fixture of the present invention, comprises the fixture of fixture mount and stationary grizzly and skirtboard frame;
Described fixture comprises the rectangular support frame for supporting and locate skirtboard frame, two lateral surfaces in each rectangle bight of described rectangular support frame are provided with a chuck, the scuncheon face that a group of described rectangular support frame is relative is fixedly installed the gripper shoe of supportive grid, the end face of described gripper shoe supportive grid is provided with the positioning tooth with the detent of the appearance profile adaptation of the lower floor's grille strip forming grid and the appearance profile adaptation with the upper strata grille strip of composition grid, and interval between the rectangular support frame medial surface of gripper shoe and gripper shoe is set the spacing space that formation one holds skirtboard frame is set,
The lateral frame board that a group of described rectangular support frame is relative is fixed in fixture mount respectively by a bearing pin, and described rectangular support frame freely can rotate around bearing pin, described fixture mount is also provided with the locking system for fixing rectangle carriage.
Further, described locking system is the latch be arranged in fixture mount, and described rectangular support frame is provided with the jack coordinated with latch;
Further, the cross section of described detent and positioning tooth is V-arrangement or isosceles trapezoid;
Further, described rectangular support frame is bolted by four pieces of lateral frame boards and forms;
Further, the supporting surface of two pieces be connected with gripper shoe in described four pieces of lateral frame boards is concaved circular cambered surface, and the supporting surface of another two pieces of lateral frame boards is plane;
Further, described chuck is active grab.
Beneficial effect of the present invention: skirt plate of railway vehicle grid welding rotary fixture of the present invention, by rectangular support frame, gripper shoe and chuck, skirtboard frame and grid are fixed on fixture by skirtboard finished size position, and during welding, rectangular support frame and gripper shoe can limit welding skirtboard deflection, ensure the skirtboard size after welding; Unclamp the locking system of this frock simultaneously, fixture can rotate arbitrarily around bearing pin, thus be fixed in fixture mount after making the adjustable reverse side of becoming a full member of fixture, therefore can complete welding of the face side of grid and rear side and skirtboard frame simultaneously in this frock, the welding tooling efficiency of skirtboard frame and grid can be improved.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the perspective view of skirt plate of railway vehicle grid welding rotary fixture of the present invention;
Fig. 2 is the schematic top plan view of rectangular support frame and gripper shoe;
Fig. 3 is chuck structure schematic diagram.
Detailed description of the invention
As depicted in figs. 1 and 2, the present embodiment skirt plate of railway vehicle grid welding rotary fixture, comprises the fixture of fixture mount 1 and stationary grizzly and skirtboard frame;
Described fixture comprises the rectangular support frame 2 for supporting and locate skirtboard frame, two lateral surfaces in each rectangle bight of described rectangular support frame are provided with a chuck 3, the scuncheon face that a group of described rectangular support frame 2 is relative is fixedly installed the gripper shoe 4 of supportive grid, the end face of described gripper shoe 4 supportive grid is provided with the positioning tooth 4b with the detent 4a of the appearance profile adaptation of the lower floor's grille strip forming grid and the appearance profile adaptation with the upper strata grille strip of composition grid, and interval between the rectangular support frame medial surface of gripper shoe 4 and gripper shoe 4 is set the spacing space 5 that formation one holds skirtboard frame is set,
The lateral frame board that a group of described rectangular support frame 2 is relative is fixed in fixture mount 1 respectively by a bearing pin 6, and described rectangular support frame 1 freely can rotate around bearing pin 6, described fixture mount 1 is also provided with the locking system 7 for fixing rectangle carriage 2.
During welding, by rectangular support frame 2, gripper shoe 4 and chuck 3, skirtboard frame and grid are fixed on fixture by skirtboard finished size position, lower floor's grille strip is stuck in the detent 4a of gripper shoe 4, and the positioning tooth 4b of gripper shoe 4 is stuck in the groove of upper strata grille strip; Skirtboard deflection when rectangular support frame 2 and gripper shoe 4 can limit welding, ensures the skirtboard size after welding.After the side of grid and skirtboard frame have welded, unclamp the locking system of this frock, made fixture be fixed in fixture mount 1 by locking system by fixture again after bearing pin 6 rotates 180 °, at this moment just can complete the opposite side of grid and the welding of skirtboard frame.By this frock can complete welding of the face side of grid and rear side and skirtboard frame simultaneously, the welding tooling efficiency of skirtboard frame and grid can be improved.
