specific Embodiment 1

[0028] Specific embodiment 1: The core of the present invention is to provide a fastening fixture for laser welding of battery modules, aiming at the unfixed position of the battery existing in the welding of the battery module, prone to weak welding and deviation of the welding position from the predetermined position , low welding efficiency and low welding yield, a targeted design of the fixture suitable for battery module welding, which can tighten and fix the battery very accurately, in order to make people in the technical field better understand The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments of the present invention. It should be noted that when an element is referred to as "fixed" or "set to" another element, it can be directly or indirectly on another component. When an element is referred to as being "connected to" another element, it can be directly or i...

specific Embodiment 2

[0029] Specific embodiment 2: as specification attached Figure 7 As shown, in order to make the present invention have a more prominent and excellent use effect during use, on the basis of the above-mentioned specific embodiment 1, the present invention provides a ball for installing the ball 30 on the left support slide 2 and the right support slide 3. The ball installation groove 29 of the ball installation groove 29 is installed with a ball 30 for the sliding of the battery installation slide seat 4. Specifically, when the ball installation groove 29 on the left support slide seat 2 and the right support slide seat 3 After the ball 30 is installed, the lower part of the battery installation slide 4 is installed on the left support slide 2 and the right support slide 3 and contacts with the ball 30 on it, which greatly improves the battery installation slide 4 on the left support slide. Slide flexibility on seat 2 and right support slide seat 3.

specific Embodiment 3

[0030] Specific embodiment 3: as specification attached Figure 11 and manual attached Figure 12 As shown, in order to make the present invention have more prominent and excellent use effects during use, on the basis of the above-mentioned specific embodiment 1, a threaded through hole is opened on the L-shaped support plate 21, and in the threaded through hole Adjusting bolts 31 are set, and a clamping plate 32 for tightening the battery pack 34 is installed on the inner end of the adjusting bolt 31. A guide sleeve 33 is fixedly installed on the clamping plate 32, and the inner end of the adjusting bolt 31 is installed on the guide sleeve. 33 and can rotate in the guide sleeve 33, specifically, in the specific use process, the adjusting bolt 31 will push the clamping plate 32 to the battery pack 34 while rotating in the threaded through hole provided on the L-shaped support plate 21. The direction of the side wall of the battery pack 34 is moved, and then the side wall of t...

Abstract

The invention relates to the field of clamps for battery module welding, in particular to a fastening clamp for battery module laser welding. The fastening clamp comprises an installation platform, aleft supporting sliding seat, a right supporting sliding seat, a battery installation sliding seat, a battery installation sliding seat driving plate, a sheathed screw, a fixing block, a first fastening member, a guiding supporting mould frame and a compressing mould frame. The left supporting sliding seat and the right supporting sliding seat are symmetrically arranged on the installation platform and are fixedly connected with the installation platform. According to the problems that weak welding, the welding position being deviated from a predetermined part, low welding efficiency and low welding yield are prone to appearing due to the fact that the position of a battery is not firm when a battery mould is welded, the clamp capable of being suitable for the battery module welding is specifically designed, and the clamp can accurately fasten and fix batteries.

Description

technical field [0001] The invention relates to the field of fixtures for battery module welding, in particular to a fastening fixture for laser welding of battery modules. Background technique [0002] In recent years, my country's automobile industry has developed rapidly. According to conservative estimates by experts, the number of automobiles will reach 130 million by 2020. The massive consumption of petroleum energy by automobiles and the resulting environmental pollution have made the transformation of transportation energy and power a global consensus. An effective way of energy consumption and environmental pollution is to develop, apply and promote new energy vehicles. International mainstream car companies, such as Ford and General Motors, have successively launched electric vehicles based on lithium-ion batteries. When producing battery modules, first, Raw materials (positive electrode material, negative electrode material, electrolyte, casing, etc.) are processed ...
