Description
Technical Field
The utility model belongs to precision equipment processing field especially relates to a processing tool of electronic scale display screen casing.
Background
The electronic scale mainly comprises a bearing system, a force transmission conversion system and a value indicating system. Wherein, the bearing system comprises a scale pan and a scale body; the force transmission conversion system comprises a lever force transmission system and a sensor; the indicating system comprises a dial and an electronic display instrument. The shell of the display screen is used as a main visible position, and the requirement on the appearance of the display screen is very high.
However, in the traditional process of processing the display screen shell, due to high requirements on the appearance of the display screen shell, the display screen shell cannot be directly butted with a numerical control machine tool, so that the polishing process of the component is very tested by the experience of operators, but the conditions of poor polishing such as appearance collapse, meat deficiency, abrasive band marks and the like are difficult to avoid, and the processing efficiency and the yield are not ideal.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an it is lower to overcome machining efficiency and yields among the prior art to and require too high defect that causes the human cost higher to the staff experience, provide a processing tool of electronic scale display screen casing.
The utility model discloses a following technical scheme solves above-mentioned technical problem:
the utility model provides a processing tool of electronic scale display screen casing which characterized in that, its include with the tool body of the display screen casing adaptation of treating processing, the position relative with the display screen casing of treating processing on the tool body is equipped with at least one air via hole, be equipped with the connector with vacuum pump connection on the tool body, every the air via hole all through the inside air flue of tool body or cavity with connector UNICOM.
Preferably, the upper surface of the jig body is a first reference surface, the first reference surface is adapted to the surface of the display screen shell to be processed, at least one group of diagonal positions of the jig body is provided with a second reference surface, and the second reference surface is adapted to a corresponding corner position on the display screen shell to be processed.
Preferably, a circle of sealing layer is arranged on the first reference surface.
Preferably, when the air via hole is communicated with the connecting port through a cavity in the jig body, the jig body comprises a lower shell and an upper shell, the upper shell is embedded on the lower shell, and the upper surfaces and the opposite lower surfaces of the upper shell and the lower shell form the cavity; the air via hole and the first reference surface are provided in the upper case.
Preferably, the jig body is provided with a connecting lock catch for processing and connecting with a numerical control machine tool.
The utility model has the advantages that: the utility model discloses a processing tool structure of electronic scale display screen casing is succinct, and convenient to use can treat that the product of processing carries out effectual location and centre gripping.
Drawings
Fig. 1 is a schematic structural view of a processing jig for a display screen housing of an electronic scale according to a preferred embodiment of the present invention.
Detailed Description
The present invention will be more clearly and completely described with reference to the following preferred embodiments and the accompanying drawings.
As shown in fig. 1, the processing jig for the display screen housing of the electronic scale in the embodiment includes a jig body 1 adapted to a display screen housing (not shown) to be processed. Two air through holes 12 are formed in the position, opposite to the display screen shell to be processed, of the upper surface of the jig body 1, and a connecting port 11 connected with a vacuum pump (not shown) is formed in the side face of the jig body 1. Each air through hole 12 is communicated with the connecting port 11 through an air passage inside the jig body 1. The tool body is provided with a connecting lock catch (not shown) for processing and connecting with a numerical control machine tool.
The upper surface (the surface to be contacted with the display screen shell to be processed) of the jig body is a first reference surface 13, four corner parts of the jig body 1 are provided with second reference surfaces 14, and the second reference surfaces 14 are matched with the corresponding corner parts of the display screen shell to be processed. Before processing, a display screen shell to be processed is placed on the jig body 1, and it is ensured that the lower surface and the corner parts of the shell correspond to the first reference surface 13 and the four second reference surfaces 14 respectively.
In addition, in order to ensure a good fixing effect between the casing and the jig body 1, a sealing layer is further arranged on the first reference surface 13, so that the influence of a gap between the casing and the jig body on the adsorption fixing effect in the working process of the vacuum pump is prevented. The sealing layer may be made of a rubber material. After the display screen casing of waiting to process is placed taking one's place, start the vacuum pump of being connected with tool body 1, the vacuum pump takes out the air between casing and the 1 contact surface of tool body clean, fixes the casing on the tool body through forming the negative pressure, can start the digit control machine tool this moment and carry out the product processing operation, closes the vacuum pump after the end and can release the product.
In other embodiments, the air passage can be replaced by the cavity structure, so as to simplify the process requirement for manufacturing the jig body and further improve the adsorption effect. Specifically, this tool body can constitute by casing and last casing down, goes up the casing and inlays to be established under on the casing to form by the upper surface of casing and the lower surface of last casing down the cavity, air via hole and first reference surface all locate on the casing.
Although particular embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are examples only and that the scope of the present invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
