Problems solved by technology

[0006] The main purpose of the present invention is to overcome and solve the shortcomings and deficiencies in the prior art. For example, most of the current welding clamping devices are only for simple two-dimensional welds or single-sided clamping devices on planar workpieces. With the three-dimensional weld More and more, it is imminent to solve the clamping problem of workpieces with any surface

Embodiment Construction

[0017] The device of the present invention will be further described in detail below in combination with schematic diagrams.

[0018] A double-sided clamping device for laser transmission welding, including an upper platen assembly 5, a small hydraulic thimble assembly 4, a handwheel adjustment mechanism 7, a lower base plate assembly 8 and a laser head 3. The upper platen assembly 5 is composed of two L-shaped platens 17, wherein the distance between the L-shaped platens can be adjusted by the adjustment hand wheel 7, so it can be flexibly applied to workpieces of various specifications, and the adjustment of the distance can not block the optical path. Each of the L-shaped pressing plates has a row of countersunk through holes, and the small hydraulic thimble assembly 4 is placed in the hole, and the thimble rod is extended and retracted under the control of the hydraulic control system 9 .

[0019] The hydraulic small thimble assembly 4 is composed of a thimble rod, a pisto...

Abstract

The invention discloses a laser transmission connection double-face clamping device and relates to the field of laser transmission welding, in particular to a clamping device for laser transmission welding plastic materials or plastic and metal materials. The laser transmission connection double-face clamping device comprises an upper pressing plate assembly, small hydraulic ejector pin assemblies, a hand wheel adjusting mechanism, a lower base plate assembly and a laser head. The upper pressing plate assembly consists of two oppositely-arranged L-shaped plates, wherein the L-shaped plates are placed vertically, a horizontal beam of each L-shaped plate is provided with a row of counter bores, and the small hydraulic ejector pin assemblies are arranged in the counter bores. Each small hydraulic ejector pin assembly can be invoked through computer programs. The lower base plate assembly consists of a working table, a left blocking plate and a right blocking plate, wherein the left blocking plate and the right blocking plate are fixed at two ends of the working table, the working table is provided with cross grooves, counter bores are evenly arranged in the grooves, and the small hydraulic ejector pin assemblies are arranged in the counter bores. The laser transmission connection double-face clamping device achieves workpiece welding, and the Z-direction control aims at guaranteeing constant defocusing amount in the welding process and facilitating table welding quality.

Description

technical field [0001] The invention relates to the field of laser transmission welding, in particular to a clamping device and a welding method for laser transmission welding plastic materials or plastic and metal materials. Background technique [0002] Laser transmission welding uses near-infrared laser as a heat source to weld two superimposed plastic materials or plastic and metal materials together. The upper material is required to be transparent to the laser beam, while the lower material should absorb the laser as much as possible. Laser transmission welding has many advantages such as fast welding speed, high precision, no pollution, non-contact welding, freedom and flexibility, and perfect weld seam. Therefore, laser transmission welding technology is widely used in various industries. [0003] At present, there are more and more researches on laser transmission welding. However, one of the biggest difficulties is that the welding clamping device limits the appli...
