Detailed Description
To further illustrate the various embodiments, the utility model provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the utility model and, together with the description, serve to explain the principles of the embodiments. Those skilled in the art will appreciate still other possible embodiments and advantages of the present invention with reference to these figures. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The utility model will now be further described with reference to the accompanying drawings and detailed description.
Referring to fig. 1 to 4, the deburring jig provided by the present embodiment includes a base 10 and a punch 20, where the base 10 is provided with a guide hole 101 and a working hole 102 located right below the guide hole 101, that is, the guide hole 101 and the working hole 102 are coaxially arranged. A hollow discharge area 103 is arranged between the guide hole 101 and the operation hole 102, so that an operator can conveniently discharge products into the operation hole 102.
The punch 20 is arranged in the guide hole 101 in a penetrating manner; realize accurate direction, prevent the skew. The operation hole 102 is a through hole, and has an upper hole section 1021 and a lower hole section 1022 with a smaller hole diameter than the upper hole section 1021, and the hole diameter of the lower hole section 1022 is slightly larger than the outer diameter of the product to be processed.
During operation, a product is placed into an upper section opening (namely an upper hole section 1021) of the operation hole 102, then the punch 20 is pressed down, and the product is pressed into a lower hole section 1022 through the upper hole section 1021 and falls out from the bottom; in the process, preliminary deburring is realized when the upper hole section 1021 starts to be pressed in; when the upper hole section 1021 is pressed into the lower hole section 1022, the removal is performed again, and the removal is more thorough; thereby obtaining a product meeting the standard; the structure is simple, the cost is low, the implementation is easy, meanwhile, the operation efficiency is high, and the quality can be well guaranteed; is very suitable for small and medium enterprises.
Specifically, in the present embodiment, the aperture of the lower hole section 1022 is 0.4mm larger than the outer diameter of the product to be processed; the upper hole section 1021 and the hole diameter are 0.7mm larger than the outer diameter of the product processed by the belt; i.e., the upper bore section 1021 and the aperture is 0.3mm larger than the lower bore section 1022. So set up, can be fine get rid of the burr, simultaneously, the product also can fall smoothly. Of course, in other embodiments, the arrangement of the aperture sizes of the upper and lower hole sections 1021, 1022 is not limited thereto. The aperture of the lower hole section 1022 is 0.1-0.5mm larger than the outer diameter of the product to be processed; the upper hole section 1021 and the hole diameter are 0.5-1.0mm larger than the outer diameter of the product processed by the belt; alternatively, the diameter of the lower hole section 1022 may be the same as the outer diameter of the product being processed.
