Detailed description of the invention
As shown in Figure 1, a kind of gusset hasp flange hold-down mechanism, the hold-down mechanism comprising angle seat 1 and be installed on angle seat 1, hold-down mechanism comprises the template 2 be connected with angle seat 1, the pneumatic cylinder 11, one-level pressing plate 6 and the pressure plate structure that are connected with template 2 hinge respectively, the guide rod chain connection of pressure plate structure bottom and pneumatic cylinder, one end is connected with one-level pressing plate via connecting plate 10, and other end top is provided with pressure head.
In the present embodiment, as shown in Figure 3, the right lower quadrant of template 2 is provided with two row's screws, for being fixedly connected with angle seat 1, template 2 is also provided with three protruding ends, is respectively used to connect one-level pressing plate 6, pneumatic cylinder 11 and pressure plate structure.
In the present embodiment, pressure plate structure is U-shaped, and the pneumatic cylinder connecting plate 7 comprising the pressing plate 9 be fixedly connected with, the pressure head 8 being located at top, pressing plate 9 one end and be fixedly connected with pressing plate 9, the bottom of pressure head 8 is provided with draw-in groove, for the pressing plate 9 that is connected together.As shown in Figure 5 and Figure 6, pressing plate 9 and pneumatic cylinder connecting plate 7 are L-type part, are bolted between the two, form U-shaped.The other end of pressing plate 9 and the bottom of U-shaped pressure plate structure are connected with the guide rod of pneumatic cylinder 11, the other end of pneumatic cylinder connecting plate 7 is connected with connecting plate 10 hinge, thus it is fixing to realize between pressing plate 9, pneumatic cylinder connecting plate 7 and pressure head 8 as a whole, and pressure plate structure and one-level pressing plate 6, connecting plate 10, being rotationally connected between pneumatic cylinder 11.
In the present embodiment, chain connection is pinned connection.Controlled by bearing pin 4 between each hinge, realize the transmission of cooperation between each part of whole mechanism and power.Simultaneously in order to prevent in use, bearing pin 4 rotates and comes off, and bearing pin 4 is provided with baffle plate 5.
Type structure of the present invention adopts the hinge between pneumatic cylinder connecting plate 7, connecting plate 10, one-level pressing plate 6 to rotate, make pneumatic cylinder 11 drive one-level pressing plate 6, progressively realize the first flange inclination of gusset hasp, then continue advance gusset hasp laminating lower line threshold and compress by pressure head 8.
Below in conjunction with the course of work the present invention is further described operation principle of the present invention.
Station welding is always spelled at automobile body-in-white, when the requirement of compression is overlapped with to gusset hasp, first gusset hasp design attitude is in advance determined, by angle seat 1, the present invention is fixed on fixture, then controlled by gas circuit, promoting SLIDE (the fixture movable device of positioning compression side wall assembly can make side wall assembly carry out planar slide) makes side wall assembly arrive and lower line assembly welding position state.Thus the present invention is moved integrally to desired location.Now, gusset hasp is in the reset condition that ground upwards vertically becomes 90 degree, and the one-level pressing plate 6 of gusset hasp flange hold-down mechanism is positioned at gusset hasp front.
When needs carry out flange compression to gusset hasp, operate the air circuit breaker of mechanism controls of the present invention, make pneumatic cylinder 11 times inlet charge, pneumatic cylinder guide rod stretches out, and promotes pressing plate 9 and travels forward, and drives pneumatic cylinder connecting plate 7 and pressure head 8 to travel forward simultaneously.Pneumatic cylinder connecting plate 7 owing to being connected with one-level pressing plate 6 by connecting plate 10, thus drives one-level pressing plate 6 to rotate when pneumatic cylinder connecting plate 7 rotates.Because one-level pressing plate 6 is in the front of gusset hasp in advance, when one-level pressing plate 6 is subject to thrust rotation, contact with gusset hasp, promote gusset hasp court and lower line lapping direction inclination flange, now gusset hasp is relative to the outward-dipping certain angle of the present invention.In the present embodiment, as shown in Figure 4, the pushing surface of one-level pressing plate 6 is designed to inclined-plane, effectively can limits gusset hasp and tilt according to inclined-plane, provide condition for pressure head 8 below contacts gusset hasp and compresses.
After one-level pressing plate 6 rotates inclination certain angle, because of the rotating rule of mechanism, one-level pressing plate 6 progressively departs from gusset hasp, move in the opposite direction, now, pressing plate 9 is with dynamic head 8 to move towards gusset hasp direction, pressure head 8 probe into one-level pressing plate 6 promote gusset hasp outwards move formed inclined spaces in, start contact with gusset hasp and compress gusset hasp, until the state relative initial position of gusset hasp revolves turnback, thorough and lower line threshold overlaps and compresses, and makes side wall assembly become to be integrated with lower line assembly, as shown in Figure 2.In the present embodiment, as shown in Figure 8, pressure head 8 pushing surface is cambered surface, is contacting and is compressing in the process of gusset hasp, and the pushing surface of cambered surface design can reduce the friction between gusset hasp, is convenient to gusset hasp and successfully surrenders according to the direction that pressure head 8 is stressed.
In order to the pressure preventing pressure head 8 place from providing is excessive, lower line threshold may be caused to be out of shape, therefore template 2 increases block 3, block 3 is positioned at cylinder connecting plate 7 downwards on the movement locus of pressing plate, play the position-limiting action of gusset hasp flange hold-down mechanism, move on after limiting the putting in place of pneumatic cylinder connecting plate 7.
When the enterprising gas port air inlet of pneumatic cylinder 11, the guide rod of pneumatic cylinder 11 is retracted, and state shown in Fig. 1 is got back to by opposite action by mechanism.
The present invention adopts gas circuit to control, and realizes the action of mechanism, and manipulation controls the button of gas circuit.Pneumatic cylinder 11 times inlet charge, guide rod stretches out, and mechanism enters compaction process, the enterprising gas port air inlet of pneumatic cylinder 11, and guide rod is retracted, and mechanism enters return course, replaces manual operation, very simple and convenient, time saving and energy saving, greatly enhances productivity.
Above-mentioned is can understand and apply the invention for ease of those skilled in the art to the description of embodiment.Person skilled in the art obviously easily can make various amendment to these embodiments, and General Principle described herein is applied in other embodiments and need not through performing creative labour.Therefore, the invention is not restricted to embodiment here, those skilled in the art, according to announcement of the present invention, do not depart from improvement that scope makes and amendment all should within protection scope of the present invention.
