Description

Technical Field

[0001] The invention relates to the technical field of automobile dash panel processing, in particular to a dash panel lower plate clamp for automobile manufacturing. Background Art

[0002] The dash panel refers to the partition between the engine compartment and the car body. It is connected to the floor and the front pillar and is installed under the dash cover. There are many holes on the dash panel, which are used for the passage of the cables, rods, pipes and wire harnesses used for operation, and also need to be matched with the installation positions of the pedals, steering columns and other parts. In order to prevent the exhaust gas, high temperature and noise in the engine compartment from entering the car body, there should be sealing measures and heat insulation devices on the dash panel. In the event of an accident, it should have sufficient strength and rigidity. Compared with other parts of the car body, the most important process technology for dash panel assembly is sealing and heat insulation, and its quality often reflects the quality of vehicle operation.

[0003] During the processing of the dash panel, some automobile accessories need to be welded to the surface of the dash panel. Since the dash panel is generally a special-shaped structure, it cannot be placed flat on the welding table for welding. At this time, it is often necessary to use a fixture to clamp the dash panel and cooperate with manual and welding robots for welding. For example, the authorized Chinese patent document publication number CN103625576B discloses a dash panel lower plate fixture for automobile manufacturing. The patent uses a cylinder or a hydraulic cylinder as a power device to drive a force transmission mechanism made by a lever principle to clamp the workpiece. It has strong stability, improves the generalization and standardization level of the fixture, increases automobile production, is suitable for assembly line production, and improves production efficiency. However, since the dash panel is generally a special-shaped structure, when some accessories are welded to the upper end of the dash panel, the angle of the dash panel cannot be adjusted, resulting in the welding robot in the welding process. Because the connection between the accessories and the dash panel is in the dead angle of the welding robot's working position, manual welding is also inconvenient, affecting the welding effect and efficiency. Therefore, we make improvements to this and propose a dash panel lower plate fixture for automobile manufacturing. Summary of the invention

[0016] Beneficial Effects

[0017] The invention provides a front panel lower plate clamp for automobile manufacturing, which has the following beneficial effects:

[0018] 1. By setting a rotating support mechanism that can freely adjust the angle and cooperating with the clamping mechanism, the inclination angle of the front panel body can be freely rotated when the clamping mechanism is clamped, so that the inclination angle of the front panel body can be adjusted as needed during welding, so that the front panel body and accessories that need to be welded can be conveniently welded, so that the welding robot will not have a welding dead angle, and it is convenient for manual welding, thereby improving the welding quality and welding speed.

[0019] 2. When it is necessary to adjust the inclination angle of the front panel body, the worker steps on the pedal to drive the front end of the limit shaft to move downward, and then drives the driving rod to rotate through the driving shaft, and then drives the upper end of the rotating block to make a circular motion through the universal shaft, and then drives the worm wheel to rotate through the worm, and the worm wheel drives the rotating shaft on the right to rotate through the flat ratchet, and cooperates with the rotating shaft on the left to drive the clamping seat to rotate a certain angle. When the pedal is stepped on to the bottom, the pedal is released, and the spring drives the front end of the limit shaft to rise, and then the driving shaft continues to drive the worm to rotate through the driving rod, connecting rod, universal shaft and rotating block. After the pedal is stepped on and the spring pushes the limit shaft to rise to complete a motion cycle, the worm rotates just one circle, and then drives the front panel body to rotate at a certain angle. By setting the limiting mechanism and the adjusting mechanism for use in conjunction, the inclination angle of the clamping seat is adjusted, which makes it more convenient to adjust the inclination angle of the front panel body and further improves the welding efficiency. 3. After the pedal is stepped on and the spring-driven limit shaft rises to complete a movement cycle, the worm gear rotates just one circle, thereby driving the front panel body to rotate at a certain angle. In the process of stepping on the pedal, the pawl is driven to slide inside the sliding seat through the connecting shaft, so that the upper end of the pawl is disengaged from the tooth opening at the lower end of the flat ratchet. At the same time, the flat ratchet rotates through the drive of the worm wheel. In the process of the pawl rising, the next tooth opening of the flat ratchet moves to the upper end of the pawl. After the pawl is fully raised, it just catches the next tooth opening of the flat ratchet, thereby limiting the flat ratchet. Finally, the rotation angle of the front panel body is limited by the rotating shaft and the clamping seat. By setting a limiting mechanism and an adjusting mechanism for use in conjunction, the inclination angle of the front panel body is limited while the front panel body is driven to adjust the angle, so that the inclined front panel body will not shake during the welding process, thereby further improving the welding quality.

[0029] The limiting mechanism 2 includes a rotating seat 21, the inside of the rotating seat 21 is rotatably connected to a driving shaft 22, the left end periphery of the driving shaft 22 is fixedly connected to a limiting shaft 23, the front end of the limiting shaft 23 is rotatably connected to a pedal 24, the lower front end of the limiting shaft 23 is fixedly connected to a spring 25, the middle periphery of the spring 25 is rotatably connected to a connecting shaft 26 through a rotating rod, the upper end opening of the connecting shaft 26 is rotatably connected to a pawl 27 through a rotating rod, the upper end of the pawl 27 is meshedly connected to a flat ratchet 28, and the middle periphery of the pawl 27 is slidably connected to the inside of a sliding seat 29;

[0030] The adjustment mechanism 3 includes a limit seat 31, the internal rotatable connection of a worm 32 of the limit seat 31, the upper end of the worm 32 is meshingly connected to a worm wheel 33, the lower end of the worm 32 is fixedly connected to a rotating block 34, the lower end of the rotating block 34 is rotatably connected to a universal shaft 35, the lower end of the universal shaft 35 is rotatably connected to a connecting rod 36, and the front end of the connecting rod 36 is fixedly connected to the inner front side of the driving rod 37.

[0031] The rotating support mechanism 1 includes a support seat 11, and the four corners of the lower end of the support seat 11 are fixedly installed with adjustable support legs 12, the upper ends of both sides of the support seat 11 are fixedly connected with bearing seats 13, and the interior of the bearing seats 13 is fixedly installed with a rotating shaft 14, and the ends of the rotating shaft 14 that are close to each other are fixedly connected to the interior of a clamping seat 15, and the upper ends of both sides of the inner side of the clamping seat 15 are fixedly connected with counterweight blocks 16.

[0032] The clamping mechanism 4 includes a base 41, and a hydraulic rod 42 is fixedly installed on the side away from the base 41.

The side away from the base 41 is fixedly connected to a lower limit port 44, and the side close to the upper end of the base 41 is fixedly connected to a limit ejector pin 45.

[0033] Specifically, the outer periphery of the front panel body 5 is placed between the upper clamping opening 43 and the lower limit opening 44, and the hydraulic rod 42 is started to drive the end of the upper clamping opening 43 located at the upper part of the lower limit opening 44 to move closer to the lower limit opening 44, thereby clamping the front panel body 5.

In the process of the pawl 27 rising, the next tooth mouth of the flat ratchet 28 moves to the upper end of the pawl 27. After the pawl 27 is fully raised, it just catches the next tooth mouth of the flat ratchet 28, thereby limiting the flat ratchet 28.

[0036] By setting up the limiting mechanism 2 and the adjusting mechanism 3 for use in conjunction, the inclination angle of the front panel body 5 is limited while driving the front panel body 5 to adjust the angle, so that the inclined front panel body 5 will not shake during the welding process, and the welding quality is further improved.

[0037] The right end of the drive shaft 22 passes through the right side of the rotating seat 21 and extends. The right end of the drive shaft 22 is rotatably connected to the lower end of the left side of the limiting seat 31. The outer periphery of the right end of the drive shaft 22 is fixedly connected to the inner periphery of the rear end opening of the drive rod 37 to facilitate driving the front end of the drive rod 37 to swing back and forth up and down.

[0038] The middle part of the flat ratchet 28 is fixedly connected to the outer periphery of the right end of the right rotating shaft 14, and the clamping seat 15 is driven to rotate by the right rotating shaft 14 to adjust the inclination angle of the front panel body 5.
