CN209279838U - Lead acid accumulator plate grid burr cubing - Google Patents

Abstract

The utility model discloses a kind of lead acid accumulator plate grid burr cubings, it is the Thin Rectangular plate that one piece of edge is equipped with scale notch.It is equipped with twice width and depth not equal notch at the one long side middle section same position of cubing, equipped with narrow notch in the middle part of wide notch bottom edge, wide notch depth is only the half of narrow notch depth, and wide notch is one times wider than narrow gap width.The narrow notch depth is equal to the maximum value of tested grid permission overlap or burr.In actual use, as long as cubing one side jaggy is mutually leaned on tested grid, whether range estimation surmounts the bottom edge of narrow notch positioned at the overlap or burr of cubing indentation, there, and not past qualified product is judged to, what is exceeded is then judged to rejected product.Such scale cubing has apparent object of reference to define when applying, and accurately differentiates whether the overlap of tested grid or burr are exceeded convenient for operative employee, so detection efficiency is high, error is small.

Description

Lead acid accumulator plate grid burr cubing

Technical field

The utility model belongs to length dimension cubing technical field, in particular, the utility model relates to one kind for examining The cubing of drafting board part burr, especially a kind of lead acid accumulator plate grid burr cubing.

Background technique

The positive and negative anodes of lead-acid accumulator are stacked by several layers grid, in order to improve lamination quality, it is necessary to finished product The overlap and burr of grid limit.The reason of grid is leadwork, and quality is relatively soft, adds structure, grasps in production Workmanship cannot be directly with the overlap or burr on vernier caliper measurement finished product grid side.The industry production in generally use range estimation or Whether Handle is qualified to qualitatively judge grid this quality index, and such qualitative checking method is although simple and easy, but right The professional qualities and working experience of operative employee have higher requirement, nevertheless, this detection method detection accuracy is relatively low, It is not able to satisfy batch production requirements.

Utility model content

The utility model mainly solves the problems, such as that existing range estimation or Handle detection accuracy are low, proposes a kind of structure letter List is easy to make, is easy to use, the preferable lead acid accumulator plate grid burr cubing of measurement accuracy.

The utility model is achieved through the following technical solutions technical goal.

Lead acid accumulator plate grid burr cubing, it is the Thin Rectangular plate that one piece of edge is equipped with scale notch.It improves it Be in: the notch of twice width and depth not etc. is equipped at the one long side middle section same position of cubing, in wide notch bottom edge Portion is equipped with narrow notch, and wide notch depth is only the half of narrow notch depth, and wide notch is one times wider than narrow gap width.

As the scheme of further improvement, narrow notch depth in the cubing, being equal to tested grid allows overlap or market Maximum value.

As the scheme of further improvement, the cubing makes of the transparent PC plastic plate of 1~3mm of thickness.

The utility model compared with prior art, has the positive effect that:

1, board-like scale card structure is simple, is easy to make, is easy to use；

2, whether exceeded convenient for the overlap or the burr size that quickly identify grid with the detection of scale cubing, therefore detection efficiency It is high；

3, with reference to analyte detection, the competency profiling to operative employee is substantially reduced.

Detailed description of the invention

Fig. 1 is the utility model structure diagram.

Specific embodiment

Below according to attached drawing and in conjunction with the embodiments, the utility model is described in further detail.

Lead-acid accumulator burr cubing shown in FIG. 1, it is the Thin Rectangular plate that one piece of edge is equipped with scale notch.It is described Cubing is the transparent PC plastic plate of one piece of thickness 1mm, sets the rectangle of twice width and depth not etc. in a long side middle section same position Notch, wide notch bottom edge middle part are equipped with narrow notch, and wide notch depth is only the half of narrow notch depth, and wide notch is wider than narrow notch It spends one times wide.The present embodiment allows overlap or burr most for detecting 50Ah lead acid accumulator plate grid, the design requirement of the grid Large scale is 2mm.Therefore, the cubing of the present embodiment production is as shown in Figure 1, the prefabricated wide 10mm of narrow notch, depth 2mm, wide The wide 20mm of notch, depth then promising 1mm.

In actual use, as long as cubing one side jaggy is mutually leaned on tested grid, range estimation is located at cubing indentation, there Overlap or burr whether surmount the bottom edge of narrow notch, not past qualified product is judged to, what is exceeded is then judged to rejected product.It is such Scale cubing has apparent object of reference to define when applying, and accurately differentiates whether the overlap of tested grid or burr surpass convenient for operative employee Mark, so detection efficiency is high, error is small.

Claims (3)

1. a kind of lead acid accumulator plate grid burr cubing, it is the Thin Rectangular plate that one piece of edge is equipped with scale notch；Its feature It is: is equipped with the rectangular notch of twice width and depth not etc., wide notch bottom edge at the one long side middle section same position of cubing Middle part is equipped with narrow notch, and wide notch depth is only the half of narrow notch depth, and wide notch is one times wider than narrow gap width.

2. lead acid accumulator plate grid burr cubing according to claim 1, it is characterised in that: the narrow notch in the cubing Depth, being equal to tested grid allows overlap or burr maximum value.
