The clamp system of fixture adopts hook pressure plate, and hook pressure plate is arranged on clamp body by hook pressure plate seat, and the thrust of hook pressure plate is provided by least one bolt, and the compaction direction of hook pressure plate is towards the supporting confined planes of support plate.
Hook pressure plate is arranged on the position near the processed hole of workpiece.
The present invention adopts technique scheme, and the bushing plate support member of fixture adopts a rod-type column, and its lower end adopts nut check, and structure is simple, supporting is reliable, good stability; Fixture adopts plane and two pits targeting scheme, and accurate positioning, machining accuracy are high; The clamp system of fixture adopts a set of hook pressure plate, and its clamping point is selected in the processed near sites of workpiece, easy to operate, reliable clamping, efficiency are high.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this description and the mark in figure are briefly described:
Fig. 1 is structural representation of the present invention (not showing in bushing plate and bushing plate pillar figure);
The schematic top plan view (not showing in workpiece figure) that Fig. 2 is structure shown in Fig. 1;
The left side that Fig. 3 is structure shown in Fig. 1 is depending on schematic diagram (workpiece, clamp system and alignment pin figure do not show).
In figure, 1 is clamp body, and 2 is bushing plate, and 3 is bushing plate pillar, and 4 is bushing plate pillar hold-down screw, and 5 is hook pressure plate, and 6 is alignment pin, and 7 is support plate, and 8 is dignity on engine air inlet tube, and 9 is hook pressure plate seat.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
The structure of the present invention expressed with Fig. 3 as shown in Figure 1, Figure 2, for screw fixture honorable on a kind of engine air inlet tube, for the Drilling operation of dignity on engine air inlet tube 8, described fixture comprises clamp body 1, location structure, clamp system and cutter guide frame, and described cutter guide frame is bushing plate 2.Wherein, clamp body 1 is the basic part of fixture.
On engine air inlet tube, dignity 8 is box typed structure, and on it, existing finished surface and hole, can be used for positioning.
The content will processed due to this operation is the hole on engine air inlet tube in dignity 8, therefore needs guider, leads to drill bit, and plays the effect increasing drill bit radial rigidity.Concrete employing bushing plate 2 leads, and by the drill bushing on bushing plate 2, leads to drill bit, improves the rigidity of drill bit, ensures the positional precision of machining hole.
In order to solve prior art Problems existing and overcome its defect, realize improving the goal of the invention of the structure of fixture and location, clamping performance, the technical scheme that the present invention takes is:
As shown in Figure 1 to Figure 3, honorable screw fixture on a kind of engine air inlet tube provided by the invention, wherein, three threaded hole one end of described bushing plate 2 are fixed on described clamp body 1 by securing member and keeper, a threaded hole one end arranges and is connected and the bushing plate pillar 3 play supporting role with it, and described bushing plate pillar 3 is perpendicular to described bushing plate 2.
Because the cantilevered length of bushing plate 2 is large, in order to improve supporting rigidity, at the external part of bushing plate 2, connected bushing plate pillar 3 is set, perpendicular to described bushing plate 2.The lower end of bushing plate pillar 3 is fixed on the base plate of clamp body.
Clamp body 1 comprises base plate and side panel; Base plate and side panel are steel plate structure.Clamp body 1 is the basic part of fixture, by having certain thickness steel plate processing and manufacturing.Its machining accuracy is higher, and intensity also can meet the demands.After each piece of plate process finishing, be fastenedly connected by threaded fastener.
Location structure comprises multiple support plate 7, and described support plate 7 is fixedly mounted on clamp body, and described support plate 7 forms a supporting confined planes; The supporting confined planes of described support plate 7 is provided with alignment pin 6, and described alignment pin 6 coordinates with the locating hole of dignity 8 on engine air inlet tube.
On engine air inlet tube, dignity 8 is box typed structure, so adopt the locate mode of plane and two pits, that is: the setting element of one side is that multiple support plate 7(on fixture are as adopted three or four support plates), the area supported of multiple support plate 7 forms a supporting confined planes, and support plate 7 is fixedly mounted on described clamp body 1; The locating surface of dignity 8 on engine air inlet tube is placed on this supporting confined planes, and two locating holes of dignity 8 on engine air inlet tube are aimed at alignment pin 6, formed and coordinate, realize location.
The setting element of two pins is alignment pin 6, comprises a straight pin and a chamfered edge pin, inserts respectively on engine air inlet tube in dignity 8 corresponding two holes, thus has carried out locating completely to dignity 8 on engine air inlet tube.
Described support plate 7 is fixedly mounted on a side panel of clamp body 1.
Described alignment pin 6 comprises a straight pin and a rhombus pin; Or, described alignment pin 6 comprise a straight pin and one cut cotter pilotage.
Alignment pin 6 has 2, and wherein one is circular pegs, and one is chamfered edge pin or rhombus pin; By the location of Position with One Plane and Two Holes, clamp system adopts hook pressure plate 5, and hook pressure plate 5 is arranged on described clamp body 1 by hook pressure plate seat 9, limits the six-freedom degree of workpiece, achieves and locate completely.
Hook pressure plate 5 is for the clamping of workpiece.The compaction direction of hook pressure plate 5 is towards the supporting confined planes of described support plate 6.
