Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to a fast switching platform and a fixture assembly. Background Art

[0002] Competition in the domestic automobile market is fierce, and product iterations are accelerating rapidly. How to adapt to the diversified needs of the market, especially the rapid rise of new energy electric vehicles, and how to achieve rapid switching of parts for different models while using the same production equipment (robots and welding tongs) on site, can not only ensure that the production site occupies less resources, but also greatly improve the efficiency of the use of automated equipment and robots.

[0003] It is very important to ensure that each time the fixture is quickly switched, it can be accurately positioned to the corresponding position, so as to ensure the consistency and stability of the product size and the consistency of the welding position.

[0004] The current switching mechanism is to fix the switching platform on the ground, and then arrange the guide on the platform, and the cylinder mechanical limit is fixed. This structure has two major disadvantages. The switching time is long, generally one workstation requires more than 10 minutes (it takes longer to push a larger fixture onto the platform or forklift slides into the platform). Since the fixture needs to be pushed from the ground to the platform, it is necessary to manually push the fixture firmly, and the guide part must be able to close the switching device. At the same time, the wheels around the fixture and the platform expansion bolts must not interfere, otherwise it cannot be pushed into place, which is laborious and time-consuming. The use of a switching platform and a cylinder clamping and positioning mechanism is more complicated and costly.

[0047] specific;

[0048] The utility model discloses a fast switching platform 1-1; it mainly comprises a switching base plate 1, on which a supporting mechanism 2, a guiding mechanism 4 and a positioning locking mechanism 3-1 are arranged; the supporting mechanism 2 is located below the switching base plate 1, and the guiding mechanism 4 extends from one end of the switching base plate 1 to the other end of the switching base plate 1; and the positioning locking mechanism 3-1 is mainly distributed at one end of the switching base plate 1, as shown in the attached figure

[0049] The quick switching platform 1-1 disclosed in the utility model is mainly a switching platform for a welding fixture 1-2. When the fixture is pushed to a predetermined position, a start button command is given to the automated robot, and quick and accurate welding can be achieved according to a predetermined trajectory, thereby ensuring the consistency and stability of the welding position and size, and easily pushing the fixture to an accurate predetermined position, thereby improving efficiency and reducing labor intensity and safety hazards. At the same time, the use of cylinder compression and filling is not adopted, which saves investment in manufacturing costs, thereby improving overall production capacity and efficiency and reducing safety hazards.

[0050] Specifically, the basis of the design of the utility model is to use the casters of the welding fixture 1-24 to be flush with the ground to manufacture a quick switching platform 1-1 with appropriate height adjustment. The quick switching platform 1-1 is fixed by adjusting bolts and angle irons 21, and the angle irons 21 are L-shaped side plates; the shell of the angle iron 21 is subsequently fixed to the ground by adjusting bolts.

When the guide wheel 1-24 of the corresponding welding fixture 1-2 is guided by the guide block 41, when the welding fixture 1-2 is subsequently used, it is required that the front guide fixing seat 1-21 of the welding fixture 1-2 is fitted with the limit block 33 on the quick switching platform 1-1 to achieve accurate and rapid positioning, and then clamped by a hand-held fixed clamp 32.

[0051] Specific implementation: easily push the welding fixture 1-2 to be replaced to push the guide wheel 1-24 into the guide block 41, then accurately limit the welding fixture 1-2 by the limit block 33, pull the handheld fixed clamp 32 to snap into the clamping block 1-22 on the welding fixture 1-2, and now the welding fixture 1-2 is switched and fixed in place.

[0052] Meanwhile, the quick switching platform 1 - 1 disclosed in the utility model mainly comprises a switching base plate 1 , and six adjustable adjusting bolts 22 on the switching base plate 1 can adjust the posture of the switching base plate 1 .

[0053] The fast switching platform 1-1 disclosed in the utility model has the following technical effects:

[0054] The hand-pushed corresponding welding fixture 1-2 can be easily moved and guided on the ground using the fixture casters 1-23 and the guide wheels 1-24. In conjunction with the guide block 41, the welding fixture 1-2 can be easily pushed into the predetermined position, saving time and effort and improving the overall switching production efficiency.

[0055] At the same time, the switching platform 1-1 uses manual clamps for clamping, which has low investment cost, does not consume kinetic energy, and has good economy.

[0056] Since there is no dedicated base, it is not necessary to consider whether there is interference between the bolts on the fixture caster 1-23 and the switching platform 1-1, inappropriate position, etc. during design. The design is simple and the installation is convenient.

[0057] This quick switching platform 1-1 can solve the problem of long production switching time of welding fixtures 1-2 for different batches of different parts of multiple models encountered in the current automated welding production process. The switching is labor-intensive and effectively solves the problem of accuracy of repeated positioning of fixtures, improves production efficiency, and significantly reduces investment costs.

[0058] Obviously, the specific implementation of the present invention is not limited by the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
