Problems solved by technology
Among them, the grab manufacturing process requires a lot of welding technology, especially the clamshell grab. The clamshell grab is mainly composed of a bucket and a jaw plate. The bucket is rolled into an arc-shaped column by a plate rolling machine after being sheared. At this time, the bucket and the jaw plate need to be welded together; in the current welding process of the grab bucket, the jaw plate is too large, heavy and irregular in shape, which is not easy to fix during the welding process, often due to unstable fixation cause misalignment during the welding process; in view of this, the present invention provides a grab welding auxiliary tool, that is, a clamshell grab jaw plate welding fixing device

The invention relates to a welding and fixing device for jaw plates of a clamshell bucket. The welding and fixing device comprises an underframe, two support lugs, a lead screw, two movable nuts, a rotating disk, a U-shaped sliding seat, a fixed longitudinal electric push rod, a T-shaped plate, two guide rods, two fixed horizontal electric push rods, a fixing disk and a suction device, wherein the two support lugs are located on the front side and the rear side of the underframe respectively, the lead screw penetrates through the support lugs at the front end of the underframe, the movable nuts are screwed in the middle positions of the lead screw, the U-shaped sliding seat is mounted above the movable nuts in an inverted manner, the bottom end of the fixed longitudinal electric push rod is connected with the top end surface of the U-shaped sliding seat, the top end of the fixed longitudinal electric push rod is connected with the T-shaped plate, two guide rods are located on two sides of the fixed longitudinal electric push rod respectively, and the suction device is mounted on the left side of the fixing disk. The welding and fixing device can fix the jaw plates before welding and can fix the jaw plates with different sizes and shapes adaptively, the fixing effect is good, and the problem of malposition in the welding process due to instable fixation is solved.
Description
technical field [0001] The invention relates to the field of grab welding machinery, in particular to a clamshell grab jaw plate welding and fixing device. Background technique [0002] The grab bucket is a bucket that can be opened and closed by grabbing sand, gravel and various bulk goods. It is a spreader that mainly relies on the opening and closing of two combined buckets on the left and right or multiple jaw plates to grab and discharge bulk materials. According to the classification of the shape, the grab can be divided into a shell-shaped grab and a orange-shaped grab. The former is composed of two complete buckets, and the latter is composed of three or more jaw plates; according to the driving method, it can be divided into hydraulic There are two types of grabs and mechanical grabs. [0003] Welding, also known as welding or welding, is a manufacturing process and technology that uses heat, high temperature or high pressure to join metal or other thermoplastic ma...
