Description

Technical Field

[0001] This utility model relates to the machining industry, and in particular to a tooling for machining thin-walled parts of new energy battery boxes. Background Technology

[0002] The battery box made of magnesium alloy is a relatively large thin-walled component, with an overall wall thickness of only 3 millimeters. Currently, the following problems exist in its manufacturing:

[0003] First, magnesium alloy extruded profiles have drawbacks such as deformation and uneven shrinkage, with errors ranging from ±0.5mm, making clamping and positioning during processing extremely difficult.

[0004] Second, because the overall wall thickness is only 3 millimeters, its strength is insufficient, and vibration will occur during processing. The resulting vibration marks will seriously affect the sealing of the battery box and the product dimensions.

[0005] Third, the battery box has 5 sides that need to be machined. Using the traditional method, it takes 5 clamping operations to complete the machining, which is inefficient. Moreover, multiple clamping operations can cause the positional accuracy of each machined surface to be compromised (due to the poor precision of the blank, resulting in inaccurate positioning).

[0006] Fourth, because it is a thin-walled part, the worker cannot guarantee that the tightening force is consistent each time during the clamping process. This will cause the workpiece to deform differently each time, thus making it impossible to guarantee the machining accuracy. Utility Model Content

[0007] The purpose of this utility model is to overcome the above-mentioned defects and provide a tooling for processing thin-walled parts of new energy battery boxes.

[0031] To make the objectives and technical solutions of this utility model clearer, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0032] like Figures 1-9 The tooling for processing thin-walled components of a new energy battery box shown includes: a four-axis base plate 1; the four-axis base plate is provided with a plurality of positioning grooves 11, a plurality of bridge pier mounting holes 12, and a plurality of mounting grooves 13; it also includes positioning blocks 2, a plurality of positioning blocks 2 being installed and fixed in the positioning grooves 11 for positioning in conjunction with the bottom plate grooves 31 of the battery box 3; each positioning groove 11 is provided with a plurality of screw holes; the positioning blocks 2 are provided with a plurality of positioning block screw holes, and the positioning blocks 2 are fixedly installed in the positioning grooves 11 by a plurality of bolts connecting and fixing the plurality of screw holes and the positioning block screw holes.

[0033] In this embodiment, the front and rear ends of the four-axis base plate are provided with two positioning grooves 11, and positioning blocks 2 are fixedly installed in the two positioning grooves respectively. The positioning blocks 2 cooperate with the bottom plate grooves 31 of the battery box 3 for positioning, thereby completing the positioning of the center position of the battery box 3. Since the battery boxes 3 are of different sizes, the corresponding bottom plate grooves 31 are also of different sizes. This utility model makes the positioning blocks 2 cooperate with the bottom plate grooves 31 by replacing the positioning blocks 2 of different sizes. That is, this utility model can replace the positioning blocks of different sizes to adapt to the product (the product blanks of the same size are sorted before processing), avoiding the trouble of using multiple sets of tooling to adapt to products of different sizes. At the same time, this tooling is mounted on a four-axis machining center, which can process four sides at a time and complete the processing of the finished product in two clamping operations, which greatly improves the processing efficiency and processing accuracy.

[0034] Piers 4, several piers are installed and fixed on the pier mounting holes 12; pressure plate 5, installed above the piers 4, is used to cooperate with the piers 4 to fix the battery box in the vertical direction; this utility model has four piers 4, two on each side, and the piers on the left and right sides are opposite each other; the pressure plate 5 spans across the left and right piers for fixed installation.

[0035] Preferably, a plurality of limiting posts 41 are provided between the bridge pier and the pressure plate. The limiting posts 41 are used to prevent the pressure plate 5 from excessively squeezing the battery box while fixing the battery box.

[0036] During fixing, first place the pressure plate above the two left and right piers 4, adjust and align the position of the bolt holes, and lock the bolts in to complete the fixing of the battery box. Since several limiting posts 41 are set on the piers, by setting the height of the limiting posts in advance, the pressure plate 5 can avoid excessively squeezing the battery box while fixing it.

[0037] The side fixing device 6 is installed on the mounting groove 13 and is used to fix the battery box 3 in the horizontal direction. The side fixing device 6 is fixed by the mounting groove having a plurality of mounting groove screw holes.

[0038] The side fixing device includes several side plates 61 and adjusting plates 62, which are symmetrically distributed on the left and right sides above the four-axis base plate. The adjusting plates 62 are installed on the inner side of the side plates 61 and are used to contact the side of the battery box 3. The side plates 61 are provided with several tightening through holes 611. The tightening through holes 611 are used to adjust the adjusting plates 62 to contact the side of the battery box 3. The side plates 61 are provided with spring-loaded through holes 612. The spring-loaded through holes 612 are provided with spring mounting positions, and the spring mounting positions are provided with springs 63, which are used to fix the battery box in the horizontal direction while avoiding excessive compression of the battery box.

[0039] When using the side wall fixing device, first place the adjusting plate 62 between the side plate 61 and the side of the battery box 3; then adjust several bolts in the tightening through holes 611 so that the adjusting plate 62 is in contact with the side of the battery box 3, but only lightly, not firmly fixed. Adjust the position of the battery box 3 back and forth so that both the front and rear ends of the battery box 3 protrude from the side wall fixing device (to facilitate processing of the front and rear ends of the battery box 3 after fixing); after adjustment, tighten the bolts in the spring-loaded through hole 612, because the spring-loaded through hole 612 is equipped with a spring mounting position, and the spring mounting position is equipped with a spring 63. This design can ensure that while fixing the battery box in the horizontal direction, excessive compression of the battery box is avoided.

[0040] The usage steps and principles of this utility model are as follows:

[0041] 1. Select positioning blocks; that is, select positioning blocks that match the battery box to be processed and install and fix them on the four-axis base plate; since this utility model can replace positioning blocks of different sizes to adapt to the product, the product blanks of the same size can be classified in advance before processing to avoid the trouble of using multiple sets of tooling to adapt to products of different sizes.

[0042] 2. Align the bottom groove of the battery box with the positioning block and place it in. Make preliminary adjustments to the position of the battery box so that both the front and rear ends of the battery box 3 protrude from the side wall fixing device (to facilitate the processing of the front and rear ends of the battery box 3 after fixing).

[0043] 3. Place the pressure plate on top of the left and right piers, adjust and align the bolt holes, and lock the bolts in. Do not lock them completely, so that the battery box can still move back and forth.

[0044] 4. Place the adjusting plate between the side plate and the side of the battery box; then adjust the bolts of the tightening through holes so that the adjusting plate is in contact with the side of the battery box, but only lightly, not firmly fixed. Adjust the position of the battery box back and forth so that both the front and rear ends of the battery box protrude from the side wall fixing device (to facilitate the processing of the front and rear ends of the battery box 3 after fixing); after adjustment, tighten the bolts in the spring-loaded through hole 612, because the spring-loaded through hole 612 is provided with a spring mounting position, and the spring mounting position is provided with a spring 63. This design can ensure that while fixing the battery box in the horizontal direction, the battery box is not excessively squeezed.

[0045] 5. Tighten the bolts between the pier and the pressure plate. Since there are several limiting posts 41 between the pier and the pressure plate, the limiting posts 41 are used to prevent the pressure plate 5 from excessively squeezing the battery box while fixing the battery box.

[0046] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0047] I. Enhanced versatility: This utility model adopts a replaceable positioning block to better suit battery box blanks of different sizes.

[0048] Second, to prevent vibration during processing, the strengthening device also has an adjustment function to accommodate the error of the blank, so that the surface roughness of the processed surface can reach 1.6um.

[0049] Third, by using a four-axis machining center, the machining can be completed in two setups, which greatly improves machining efficiency and reduces positioning errors caused by multiple setups.

[0050] Fourth, the addition of a limiting device ensures that even if the worker applies excessive force when tightening, it will not cause additional clamping force on the product, thus preventing product deformation and guaranteeing its processing accuracy.

[0051] Fifth, the clamping is simple and can ensure the processing accuracy of the product without the need for professional personnel.
