Abstract
A checking tool for checking embedded screws comprises a mounting plate (1) and 10 embedded screw detection holes (2). The checking tool is characterized in that the embedded screw detection holes (2) are made in the mounting plate (1) by wire-cut electrical discharge machining. The sizes of the embedded screw detection holes (2) are correspondingly in different tolerance ranges of M3 to M8; the sizes of standard embedded screws in the ranges of M3 to M8 are detected. The checking tool is simple, can run stably and reliably and allows the sizes of the embedded screws to be conveniently and quickly detected; the embedded screw detection holes in the checking tool are applicable to detecting the sizes of the standard embedded screws in the ranges of M3 to M8; the problem that the sizes of the existing embedded screws have errors in certain ranges, thereby resulting in significantly decreased injection molding productivity, is solved.
Description
Technical field
The present invention relates to a kind of testing tool of standardized element, especially plastic products are installed the testing tool of pre-buried screw sizes.
Background technology
Many plastic products all need to assemble with other part, and for ensureing the intensity of the rear plastic products of assembling, generally in the process of plastic products injection moulding production, plastic installation position embeds pre-sunk screw.Because screw hole aperture size pre-buried on injection mold is fixed, and pre-buried screw sizes has the error of certain limit, cause some pre-sunk screw to be arranged in mould and have comparatively wide arc gap, and some pre-sunk screw cannot be installed in hole corresponding to mould, when adopting this kind of method operation, the work efficiency that injection moulding is produced is lower, and also can make troubles during operation, thus increases production cost.Pre-sunk screw is arranged on tension in injection mold, ejects generation considerable influence to mould, plastic products also can be caused to eject and turn white, the phenomenon even ftractureed.
Summary of the invention
In order to ensure the accuracy requirement in pre-sunk screw detect aperture aperture, the object of the present invention is to provide a kind of structure simple, the cubing of the pre-sunk screw that using state is reliable and stable, pass through low-speed WEDM, linear cutter goes out 10 pre-sunk screw detect aperture on a mounting board, pre-buried screw sizes can detect the standard within the scope of M3 ~ M8.The margin tolerance that pre-sunk screw detect aperture size is corresponding different.
Technical scheme provided by the invention is: a kind of cubing of pre-sunk screw, be made up of installing plate, pre-sunk screw detect aperture, on described installing plate, linear cutter goes out 10 pre-sunk screw detect aperture, the margin tolerance that 10 corresponding M3 ~ M8 of pre-sunk screw detect aperture size are different, and the pre-buried screw sizes of the standard within the scope of M3 ~ M8 is detected.
The material of described installing plate is Cr12, and it is 48 ~ 50HRC that heat treatment hardness requires, 10 on installing plate pre-sunk screw detect aperture adopt low-speed WEDM processing.
The present invention, device is simple, and working stability is reliable.Can the cubing of the pre-buried screw sizes of convenient, fast detection, the pre-sunk screw detect aperture in cubing, pre-buried screw sizes can detect the standard within the scope of M3 ~ M8.Solve existing pre-buried screw sizes error within the specific limits, cause the problem that injection moulding production efficiency significantly declines.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the tolerance of 10 pre-sunk screw detect aperture.
Embodiment
See accompanying drawing 1, Fig. 2, the cubing of pre-sunk screw of the present invention comprises: installing plate 1 and pre-sunk screw detect aperture 2.In order to ensure the accuracy requirement in pre-sunk screw detect aperture aperture, processed by low-speed WEDM, on installing plate 1, linear cutter goes out 10 pre-sunk screw detect aperture 2, pre-buried screw sizes can detect the standard within the scope of M3 ~ M8.The margin tolerance that pre-sunk screw detect aperture 2 size is corresponding different.In use, according to the specification of pre-sunk screw, according to the model of mark on installing plate 1, corresponding pre-sunk screw detect aperture 2 of putting into detects pre-sunk screw.If pre-sunk screw can by detect aperture 2 on installing plate 1, just representing that pre-buried screw sizes meets the tolerance of design, is qualified part; On the contrary, if pre-sunk screw can not by detect aperture 2 on installing plate 1, just representing that pre-buried screw sizes cannot meet the tolerance of design, is rejected part.Cubing pre-sunk screw detect aperture 2 pre-buried screw sizes can detect the standard within the scope of M3 ~ M8.
Because pre-buried screw number is more, in order to ensure that installing plate 1 is in actual production use procedure, the precise decreasing that pre-sunk screw detect aperture 2 causes because constantly rubbing, the manufactured materials of installing plate 1 is Cr12, and heat treatment hardness requires to reach 48 ~ 50HRC.
Claims (2)
1. the cubing of a pre-sunk screw, be made up of installing plate (1), pre-sunk screw detect aperture (2), it is characterized in that: the upper linear cutter of described installing plate (1) goes out 10 pre-sunk screw detect aperture (2), the margin tolerance that 10 corresponding M3 ~ M8 of pre-sunk screw detect aperture (2) size are different, and the pre-buried screw sizes of the standard within the scope of M3 ~ M8 is detected.
2. the cubing of a kind of pre-sunk screw according to claim 1, is characterized in that: the material of described installing plate (1) is Cr12, and 10 on installing plate (1) pre-sunk screw detect aperture (2) adopt low-speed WEDM processing.
