Abstract
The utility model discloses a reinforcement clamping single supporting arm type self-locking mechanism of an automobile welding fixture. The reinforcement clamping single supporting arm type self-locking mechanism comprises a first self-locking machine, a second self-locking machine, a swing rod, a support seat, a first cylinder, a second cylinder, a connecting rod, a compaction block, a rocker arm and a rotating shaft, wherein the first self-locking machine is connected with the rocker arm, the first cylinder is connected with the first self-locking machine and drives the first self-locking machine, the compaction block is connected with the rocker arm and the swing rod, the connecting rod is connected with the swing rod, the swing rod is connected with the support seat through the rotating shaft, the second cylinder is connected with the second self-locking machine and drives the second self-locking machine, and the second self-locking machine is arranged on the support seat. According to the utility model, by applying a mechanical principle, the smaller output of the cylinder is realized and the larger clamping force is provided.
Description
Technical field
The utility model relates to a kind of self-locking mechanism, and particularly a kind of automobile welding and assembling clamp reinforcement clamps single arm-type self-locking mechanism that supports.
Background technology
[0002] vehicle body of automobile all is welded by sheet metal component now, and sheet metal component all has the curved surface in space, complex structure mostly.Receive the influence of Sheet Metal Forming Technology, sheet metal component also all exists resilience except the distortion that self is arranged.Especially the thicker sheet metal component of using for vehicle frame, the distortion of sheet metal component self and springback capacity are difficult to control especially, and are CO mostly for vehicle frame
2(carbon dioxide) welding, this welding manner have also determined bigger deflection can occur after the welding.
Summary of the invention
[0003] the utility model technical problem to be solved provides a kind of automobile welding and assembling clamp reinforcement and clamps single arm-type self-locking mechanism that supports, and it realizes less the exerting oneself of cylinder through the principle of using machinery, and bigger clamping force is provided.
For solveing the technical problem, the utility model provides a kind of automobile welding and assembling clamp reinforcement to clamp single arm-type self-locking mechanism that supports, and it is characterized in that; It comprises first self-locking device, second self-locking device, fork, supporting seat, first cylinder, second cylinder, connecting rod, compact heap, rocking arm, rotating shaft; First self-locking device is connected with rocking arm, and first cylinder is connected with first self-locking device and drives first self-locking device, and compact heap is connected with rocking arm, fork; Connecting rod is connected with fork; Fork is connected with supporting seat through rotating shaft, and second cylinder is connected with second self-locking device and drives second self-locking device, and second self-locking device is installed on the supporting seat.
The positive progressive effect of the utility model is: the utility model is realized less the exerting oneself of cylinder through the principle of using machinery, and bigger clamping force is provided, and realizes the distortion of control vehicle frame in welding process
Amount.The utility model can reduce CO
2The distortion of the vehicle frame that causes in the welding process reduces the workload of follow-up orthopedic station.The utility model provides larger clamping force through less cylinder, the cost of the cylinder of saving, and it is little that mechanism is taken up room.The utility model can be corrected bounce-back, the distortion of sheet metal component self to a certain extent.
Description of drawings
Fig. 1 is that the utility model automobile welding and assembling clamp reinforcement clamps single structural representation that supports arm-type self-locking mechanism.
The specific embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
As shown in Figure 1; The utility model automobile welding and assembling clamp reinforcement clamps and singly to support arm-type self-locking mechanism and comprise first self-locking device 1, second self-locking device 2, fork 3, supporting seat 4, first cylinder 5, second cylinder 6, connecting rod 7, compact heap 8, rocking arm 9, rotating shaft 10; First self-locking device 1 is connected with rocking arm 9, and first cylinder 5 is connected with first self-locking device 1 and drives first self-locking device 1, and compact heap 8 is connected with rocking arm 9, fork 3; Connecting rod 7 is connected with fork 3; Fork 3 is connected with supporting seat 4 through rotating shaft 10, and second cylinder 6 is connected with second self-locking device 2 and drives second self-locking device, 2, the second self-locking devices 2 and is installed on the supporting seat 4.
First self-locking device is the auto welding jig a kind of self-locking mechanism that arrives commonly used, and its basic principle also is the dead point that has used quadric chain, realizes self-locking, is exactly that first cylinder does not have pressure after the self-locking, and the application of force can not be with mechanism opening on rocking arm fully.Second self-locking device is a kind of distortion of linkage, respectively connects a connecting rod about the joint of second cylinder, and the connecting rod of both sides links to each other with fork respectively again, and fork is connected with supporting seat through rotating shaft, and compact heap directly compresses sheet metal component.Drive two connecting rod motions through second cylinder, when the turning point of two connecting rods was on the same straight line, two forks were realized self-locking to the mutual balance of the power of connecting rod.Second self-locking device also is the self-locking mode of using mechanically, in theory not
Destroy under the prerequisite of mechanism, the bounce of the sheet metal component that the upper end compact heap receives, distortion tension force can be infinity.
Though more than described the specific embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these embodiments.Therefore, the protection domain of the utility model is limited appended claims.
