Description
本發明係有關於一種提供固定加工件的定位塊，以利加工機械做各種加工，尤指可以針對加工件的側面大量且快速的夾持。 The present invention relates to a positioning block for providing a fixed workpiece for facilitating various processing by a processing machine, and in particular for large and rapid clamping of the side of the workpiece.
按，目前的自動控制加工機為了快速、方便進行加工，所有的加工件均會利用一治具盤來對加工件加緊後，上、下料於自動控制加工機，尤指一種針對加工件側邊進行夾持，使加工件上段及上方可以被加工的定位塊組。 According to the current automatic control processing machine, in order to process quickly and conveniently, all the processed parts will use a jig plate to tighten the processed parts, and the upper and lower materials are automatically controlled by the processing machine, especially for the workpiece side. The positioning block group can be processed while the upper part and the upper part of the workpiece are clamped.
目前可供加工件側邊進行夾持的定位塊組專利，如第M501318號的「小型夾具改良構」，第I482685號的「虎鉗組、虎鉗組之活動式虎鉗及固定式虎鉗」，第339003號的「可雙向配合夾持定位的夾具結構」，其每一定位塊組結構均係利用一螺絲鎖結一錐型套，再配合於錐型套兩對應側的滑塊，該滑塊對應錐型套有斜面，使螺絲鎖結錐型套時，能以錐型套控制斜面使滑塊產生往外的滑移，以產生定位夾持加工件，而兩滑塊間的兩側邊還設有彈簧，以使螺絲退回時滑塊可以歸位，該種設計具有下述缺點，一、每一組定位塊組僅能針對二加工件的其中一面固定，因此需要多組定位塊組才能供多數加工件固定，轉動多數螺絲的過程，費時又費工，不利於加工量產；二、且使用越多組夾具所佔用空間越大，相對 排擠加工件的設置；三、一組定位塊組需包含一螺絲、一錐型套、二滑塊及二彈簧，結構多且複雜，成本又高。 At present, the positioning block group for the side of the workpiece can be clamped, such as the "Miniature Fixture Improvement" of No. M501318, the "Wag Set, the Vise and the Fixed Vise of the Vise Group" "No. 339003" "Clamping structure for two-way clamping and positioning", each positioning block group structure is locked with a taper sleeve by a screw, and then matched with the slider of the two corresponding sides of the cone sleeve. The slider has a beveled surface corresponding to the tapered sleeve, so that when the screw locks the tapered sleeve, the inclined sleeve can be controlled by the tapered sleeve to cause the slider to slide outward to generate the positioning and clamping workpiece, and the two between the two sliders The side is also provided with a spring so that the slider can be returned when the screw is retracted. This design has the following disadvantages: First, each set of positioning block can only be fixed for one side of the two workpieces, so multiple sets of positioning are required. The block group can be used for fixing most of the workpieces. The process of rotating most screws is time-consuming and labor-intensive, which is not conducive to processing and mass production. Second, the more space is used, the larger the space occupied by the fixtures is. The arrangement of the extrusion processing parts; three, a set of positioning block group needs to include a screw, a cone type sleeve, two sliders and two springs, the structure is complicated and complicated, and the cost is high.
本發明人有鑑於習知定位塊組結構具有操作費時又費工，不利於加工量產、佔用空間越大，排擠加工件的設置、結構多且複雜，成本高的缺失，是以乃思及創作的意念，經多方探討設計與試作樣品試驗，及多次修正改良後，終設計出本創作。 The inventor has in view of the fact that the conventional positioning block group structure has time-consuming and labor-intensive operation, which is disadvantageous for processing mass production and occupying space, and the arrangement and structure of the extrusion processing parts are complicated and complicated, and the cost is high.
