Description
Technical Field
The utility model relates to the field of CNC (computer numerical control) processing of PCB (printed circuit board), in particular to an auxiliary positioning auxiliary jig.
Background
CNC index machines are programmed with a numerical control machining language, typically G-codes. CNC machining has great advantages over manual machining, such as the fact that CNC machining produces parts that are very accurate and repeatable; CNC machining can produce parts with complex contours that cannot be done by manual machining. CNC machining has been widely used in the field of machining, and is a development trend and an important and necessary technical means for die machining.
When the CNC is processed, part of products with high end and high quality requirements are processed, the appearance requirements of customers on the PCB are very strict, the design of the products does not meet the requirements of the traditional CNC processing mode, and the traditional PTH hole positioning or simple tape sticking positioning can generate high-proportion poor quality.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a CNC positioning auxiliary jig for product positioning.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
the CNC positioning jig comprises a positioning substrate and a positioning groove formed in the positioning substrate, wherein a plurality of groups of positioning and fixing components are arranged in the positioning groove, each positioning and fixing component comprises a plurality of positioning and fixing blocks, positioning spacer blocks are arranged between the two positioning and fixing blocks, and positioning holes are formed in four corners of the positioning groove and in the positioning substrate.
In one embodiment, a plurality of sets of the positioning fixing assemblies are arranged in parallel in the positioning grooves.
In one embodiment, the positioning fixture is comprised of L blocks and 7 blocks.
In one embodiment, the L-block is integrally formed with the 7-block.
In one embodiment, the depth of the positioning groove is 2mm + -5 um.
In one embodiment, the number of the positioning holes is four, and the diameters of the four positioning holes are 2.0-3.0 mm.
In one embodiment, the positioning substrate, the positioning fixing block and the positioning spacer block are made of phenolic aldehyde base plates with the thickness smaller than 5 mm.
Compared with the prior art, the utility model has the following beneficial effects:
the utility model passes through the locating base plate, locating groove on locating base plate, there are multiple groups of locating fixed assemblies in locating groove, locating fixed assembly include multiple locating fixed blocks, there are locating spacer blocks between two locating fixed blocks, and locating hole is set up on locating base plate in four corners of locating groove; therefore, the CNC positioning jig does not need to use PTH hole operation positioning holes in the set unit, does not need to use adhesive tape to fix products for routing, and does not generate poor quality such as PTH positioning hole explosion holes, plate surface adhesive tape printing/adhesive marks and the like by applying the novel CNC positioning jig, so that the customer appearance zero defect requirement can be completely met.
Drawings
Fig. 1 is a schematic structural diagram of embodiment 1 of the present utility model.
In the figure: 10. the device comprises a positioning substrate, 20, a positioning groove, 30, a positioning fixing block, 40, a positioning spacer block, 50 and a positioning hole.
Detailed Description
The utility model is further described below with reference to the drawings and examples.
Example 1
As shown in fig. 1, the embodiment includes a positioning substrate 10 and a positioning groove 20 formed on the positioning substrate 10, wherein a plurality of sets of positioning and fixing components are arranged in the positioning groove 20, each positioning and fixing component includes a plurality of positioning and fixing blocks 30, positioning spacer blocks 40 are arranged between two positioning and fixing blocks 30, and positioning holes 50 are formed at four corners of the positioning groove 20 and on the positioning substrate 10; therefore, the PCS board can not move during CNC forming through the arrangement of the positioning grooves 20, the plurality of positioning fixing blocks 30 and the positioning spacer blocks 40, and the purpose of positioning without positioning holes is achieved.
A plurality of groups of the positioning and fixing components are arranged in parallel in the positioning groove 20; the positioning and fixing block 30 consists of L blocks and 7 blocks, and the L blocks and the 7 blocks are integrally formed; in this embodiment, the lateral ends of the L blocks and the lateral ends of the 7 blocks form rectangular blocks, and the periphery is chamfered.
In the present embodiment, the depth of the positioning groove 20 is 2mm±5um; the number of the positioning holes 50 is four, and the diameters of the four positioning holes 50 are 2.0-3.0 mm.
In addition, the positioning substrate 10, the positioning fixing block 30 and the positioning spacer block 40 are made of phenolic aldehyde base plates with the thickness smaller than 5 mm; therefore, the CNC positioning jig does not need to use PTH hole operation positioning holes in the set unit, does not need to use adhesive tape to fix products for routing, and does not generate poor quality such as PTH positioning hole explosion holes, plate surface adhesive tape printing/adhesive marks and the like by applying the novel CNC positioning jig, so that the customer appearance zero defect requirement can be completely met.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the technical solution of the present utility model has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that the technical solution described in the foregoing embodiments may be modified or some of the technical features thereof may be equally substituted; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
