Problems solved by technology

[0003] The existing forming process of aluminum alloy battery trays is mainly welding. The thermal conductivity and specific heat of aluminum alloy itself are more than twice that of traditional steel parts, resulting in a large expansion coefficient during the welding process. Feedback to the product is an uncontrollable deformation of the product Big
[0004] When further welding or machining the semi-finished products that have been welded in the production process of aluminum alloy battery trays, the traditional positioning and clamping methods cannot be accurately positioned in the subsequent processes due to the large welding deformation of the products in the previous process, and it is necessary to rely on manual positioning for each The product is centered; and the flatness of the product is about 1.5mm. The fixed support will cause the side support point to hang due to the flatness problem.
[0005] One of the existing tooling schemes is to use a horizontal fixed reference block for positioning: such as figure 1 Use two sides to lean against the fixed reference block 1', and apply force from two opposite directions (the force mechanism can be electricity, gas, liquid, etc.), so that the product can stick to the fixed reference block 1' to play

Embodiment 1

[0045] The utility model relates to a two-way centered positioning and double-wedge floating self-locking fixed tooling, which includes a main body of the tooling, on which a product to be clamped is fixed.

[0046] The main body of the tooling includes a structural bottom plate 600, on which are arranged a lifting ring 100, a material guide mechanism 200, a two-way automatic centering mechanism 500, a double oblique wedge self-locking floating support mechanism 400 and an automatic guiding and pressing mechanism 300:

[0047] The two-way automatic centering mechanism 500 can ensure the positioning requirements of the product to be clamped in the horizontal direction;

[0048] The double-wedge self-locking floating support mechanism 400 can ensure that all contact points in the vertical direction are in floating fit with the product 1 to be clamped, thus greatly solving the impact of product processing deformation on subsequent further finishing;

[0049] The automatic straigh...

Embodiment 2

[0075] The utility model relates to a two-way centered positioning and double oblique wedge floating self-locking fixed tooling for an aluminum alloy battery tray, which includes a main body of the tooling, on which the aluminum alloy battery tray is fixed.

[0076] Clamp the aluminum alloy battery tray on the main body of the tooling, and then finish machining in the CNC equipment to obtain 74 machining holes. The CNC finishing process requires high consistency in the relative positions of different products, otherwise the machining holes will be out of position Or in the case of a hole, and the aluminum alloy battery tray is required to be in a global clamping state, and the support points should be avoided as much as possible.

[0077] The main body of the tooling mainly includes the automatic guiding and pressing mechanism 300 of the first embodiment, the double-wedge self-locking floating support mechanism 400 and the bidirectional automatic centering mechanism 500 .

Abstract

The invention discloses a two-way centering positioning and double-wedge floating self-locking type fixing tool which comprises a tool main body; a to-be-clamped product is fixed on the tool main body; the tool main body is further provided with a two-way automatic centering mechanism, a double-wedge self-locking floating supporting mechanism and an automatic guiding and compression mechanism; thetwo-way automatic centering mechanism realizes positioning of the to-be-clamped product in a horizontal direction; all contact points of the double-wedge self-locking floating supporting mechanism ina vertical direction are attached to the to-be-clamped product in a floating manner; and the automatic guiding and compression mechanism vertically acts downward to press the to-be-clamped product. By means of the mode, the two-way centering positioning and double-wedge floating self-locking type fixing tool can effectively guarantee the positioning requirements for the product in the horizontaldirection and floating attachment of all the contact points in the vertical direction to the product, eliminates the influence of product machining deformation on subsequent further finish machining,realizes complete constraint of the product, ensures the quality of the product and meets the requirements for batch production.

Description

technical field [0001] The invention relates to the technical field of forming battery trays, in particular to a two-way centered positioning and double-wedge floating self-locking fixing tool. Background technique [0002] In recent years, the new energy vehicle industry has developed rapidly. As the carrier of new energy vehicle batteries, lightweight aluminum alloy battery trays have become the mainstream choice, and tooling solutions for battery tray processing are also urgently needed. [0003] The existing forming process of aluminum alloy battery trays is mainly welding. The thermal conductivity and specific heat of aluminum alloy itself are more than twice that of traditional steel parts, resulting in a large expansion coefficient during the welding process. Feedback to the product is an uncontrollable deformation of the product Big. [0004] When further welding or machining the semi-finished products that have been welded in the production process of aluminum allo...
