Description

Technical Field

[0001] This application relates to the field of welding tooling technology, and in particular to a mobile workpiece clamping device. Background Technology

[0002] Most welding platforms are equipped with fixtures to hold the workpieces to be welded. However, many workpieces require multiple welding operations from multiple angles due to their size, shape, or other factors. Since the fixtures are fixed, they cannot move the workpieces and cannot effectively accommodate multiple welding stations within a limited space, such as multiple welding robots welding simultaneously. Furthermore, welding robots are expensive and have a limited welding range, making them unsuitable for welding operations from multiple angles. Therefore, a movable workpiece clamping device is needed to clamp the workpiece while simultaneously moving it to different welding stations, facilitating multiple welding operations from multiple angles.

The end clamping rod 305 is driven by an end power element set on the end clamping frame 301 to clamp the main steel plate 101 on the end clamping frame 301. End pressure blocks 306 corresponding to end pads 303 are set on both sides of the end of the end clamping rod 305. By setting the end pressure blocks 306 on the end clamping rod 305, corresponding to the end pads 303, the main steel plate 101 is clamped.

[0062] The end power element includes an end hinge shaft 307 mounted on an end clamping frame 301, an end clamping rod 305 coaxially fixed to the end hinge shaft 307 and using the end hinge shaft 307 as the hinge axis, an end gear coaxially fixed on the end hinge shaft 307, and an end cylinder 308 fixedly mounted on the end clamping frame 301.

[0069] The intermediate clamping mechanism 6 is located on the right side of the clamping base plate 2, between the two clamping mechanisms, and is used to position and clamp the main steel plate 101 from the middle.

[0070] The intermediate clamping mechanism 6 includes an intermediate clamping frame 601 fixedly connected to the clamping base plate 2.

[0071] The intermediate power component includes an intermediate hinge shaft 607 mounted on an intermediate clamping frame 601, an intermediate clamping rod 605 coaxially fixed to the intermediate hinge shaft 607, with the intermediate hinge shaft 607 serving as the hinge axis, an intermediate gear coaxially fixed on the intermediate hinge shaft 607, and an intermediate cylinder 608 fixedly mounted on the intermediate clamping frame 601. An intermediate rack meshing with the intermediate gear is fixedly mounted on the telescopic rod of the intermediate cylinder 608. The operation of the intermediate cylinder 608 drives the intermediate gear to rotate, which in turn drives the intermediate clamping rod 605 to swing, causing the intermediate pressure block 606 to clamp or release the main steel plate 101.

[0072] The auxiliary positioning mechanism 7 is provided on the left side of the clamping base plate 2, which can be adapted to the positioning and clamping between the left steel plate 102 of the triangle and the main steel plate 101.

The slide block 701 is mounted on the clamping base plate 2 in cooperation with the slider A and the slide rail A702. The sliding power element 703 is fixed on the clamping base plate 2. The sliding power element 703 can be a cylinder. The slide block 701 is slidably mounted on the clamping base plate 2 by the sliding power element 703. The lifting cylinder 704 is fixed on the slide block 701 by the lifting cylinder seat 705. The lifting block 706 is fixedly mounted on the end of the extension rod of the lifting cylinder 704. The lifting block 706 is located on the side of a left support rod 401. The auxiliary positioning pin 707 and the auxiliary detection sensor 708 are mounted on the lifting block 706.

[0074] The sliding power element 703 drives the slide block 701 to slide on the clamping base plate 2, realizing the movement of the lifting block 706, which moves closer to or away from the left support rod 401. When the lifting block 706 is in a position close to the left support rod 401, it can replace the left positioning pin 404 and the left detection sensor 405 in a nearby left clamping mechanism 4, adapting to different positioning of the left steel plate 102, that is, it can be adapted to the triangular left steel plate 102. Through the setting of the auxiliary detection sensor 708, the triangular left steel plate 102 placed on the left pad 403 can be detected to detect whether the placement position of the left steel plate 102 is accurate. Through the setting of the auxiliary positioning pin 707, it can cooperate with the hole of the left steel plate 102 placed on the left pad 403, and the pin hole cooperation realizes the positioning of the left steel plate 102.

[0075] When it is necessary to weld another type of steel plate workpiece 1 (such as...) Figure 12 When a trapezoidal left steel plate 102 is replaced with a triangular left steel plate 102 and welded to the main steel plate 101, the sliding power element 703 drives the slide block 701 to slide, causing the lifting block 706 to move to the bottom of the triangular left steel plate 102. The lifting block 706 is then lifted by the lifting cylinder 704. After the main steel plate 101 is placed, the triangular left steel plate 102 is placed on the left pad block 403. At the same time, the hole on the triangular left steel plate 102 mates with the hole shaft of the auxiliary positioning pin 707, and the auxiliary detection sensor 708 detects whether the triangular left steel plate 102 is in place. After the triangular left steel plate 102 is placed, the left pressure block 407 presses down to press the left steel plate 102 tightly, thus achieving the positioning and clamping of the triangular left steel plate 102.

[0077] The movable base 801 includes two spaced-apart square tubes, which are fixedly connected by several connecting pipes. The movable base 801 is composed of square tubes, resulting in a simple and stable structure. The bottom of the movable base 801 is supported by multiple support seats.

[0078] The movable base plate 802 is slidably engaged with the movable base 801 via slider B and slide rail B803. Slider B is connected to the movable base plate 802 via slider connecting plate 804. Slide rails B803 are provided on both square tubes, and sealing plates 805 are provided on both square tubes. The two sides of the sealing plates 805 are connected to the two square tubes via support plates 806. The slide rails B803 are located below the sealing plates 805. The sealing plates 805 provide a certain degree of enclosure, preventing other items from falling between the two square tubes, i.e., inside the movable base 801, and also protect the slide rails B803.

[0079] A movable rack 807 is mounted on the movable base 801, and a movable motor 808 is mounted on the movable base plate 802.
