It is L shaped that two described connecting plates are, and the one side all is fixed on described index dial, is provided with connecting hole on another side.Two described connecting plates are connected with the workpiece bushing plate with attachment screw by connecting hole, can fixation workpiece on described workpiece bushing plate.Described pinion stand is connected with described cant board by screw, and described connecting plate and described index dial are connected by screw.
The beneficial effects of the utility model are:
1, the utility model separates several operating angles on index dial, mix again the bushing plate of angle separately, clamped one time just can be processed the hole of multiple directions, especially to comparatively heavy workpiece, reduced the carrying clamping times, reduce labour intensity, improved efficiency, and improved the precision of relative position.
2, the utility model drives the motion of location tooth bar by handle, gear shaft and gear, the front end of location tooth bar can insert in the locating hole arranged on index dial, realize the calibration location, in addition, the rear end of location tooth bar is provided with spring, can effectively prevent from locating tooth bar from locating hole, naturally deviating from, avoid occurring waste product.
3, the utility model index dial is connected with the cant board rotary type by bearing, rotates flexibly, is convenient to adjust the anglec of rotation, in addition, index dial be connected the movable connection of bent plate employing, can fast assembling-disassembling, easy to use, efficiency is high.
4, the utility model cant board and base plate adopt movable connection, and easy disassembling is convenient to processing, reduces use cost.
5, reasonable in design, easy to use, the accurate positioning of the utility model and laborsaving saving time, it is applied widely,
Be easy to promotion and implementation, have good economic benefit.
The accompanying drawing explanation:
Fig. 1 is the structural representation of convertible multi-angle drilling positioner;
Fig. 2 is the side view of convertible multi-angle drilling positioner shown in Figure 1.
The specific embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, in figure, 1-base plate, 2-cant board, 3-bearing, 4-alignment pin, 5-gear, 6-pinion stand, 7-index dial, 8-connecting plate, 9-workpiece bushing plate, 10-handle, 11-spring, 12-workpiece, 13-gear shaft.
Convertible multi-angle drilling positioner contains base plate 1, wherein, the two ends, left and right of base plate 1 are connected with the lower end of two cant boards 2 respectively, the middle part of two cant boards 2 is connected with two index dial 7 rotary types respectively by bearing 3, on each index dial 7, be provided with locating hole and connecting plate 8, on each cant board 2, be provided with an alignment pin 4, the locating hole on alignment pin 4 front ends and index dial 7 is complementary; Alignment pin 4 rear ends are provided with tooth bar, and this tooth bar is meshed with the gear 5 on being arranged on gear shaft 13 1 ends, and gear shaft 13 is arranged in pinion stand 6, and pinion stand 6 is fixed on cant board 2, and the other end of gear shaft 13 is equipped with handle 10.
Rack rear is sleeved in a cavity, cavity has strip hole with respect to the position of tooth bar, be convenient to rack and pinion 5 engagements, cavity is fixed on cant board 2, between tooth bar rear end and cavity inner wall, be provided with spring 11, spring 11 tightly inserts in the locating hole of index dial 7 alignment pin 4 front ends, prevents from automatically deviating from.
It is L shaped that two connecting plates 8 are, and the one side all is fixed on index dial 7, is provided with connecting hole on another side.Two connecting plates 8 are connected with workpiece bushing plate 9 with attachment screw by connecting hole, can fixation workpiece on workpiece bushing plate 9.
Pinion stand 6 is connected with cant board 2 by screw, and connecting plate 8 is connected by screw with index dial 7, is convenient to dismounting and processing.
Operation principle: workpiece is fixed on workpiece bushing plate 9, workpiece bushing plate 9 is fixed on two connecting plates 8, otherwise at left end, stir clockwise handle 10(right-hand member), driven gear axle 6 and gear 5 rotations, tooth bar is moved to the left, from index dial 7, exiting, rotational workpieces bushing plate 9 is to when boring position, alignment pin 4 enters in the locating hole of index dial 7 automatically by spring force, workpiece bushing plate 9 is in running order, because workpiece bushing plate 9 and connecting plate 8 are fixed together, by two ends index dial 7 and two tooth bar location, workpiece bushing plate 9 is very steady, the perpendicularity of the perpendicular locating surface of holing is in 0.03, the centre-to-centre spacing of holing can be controlled at ± 0.04 within.This frock can be according to the boring demand of workpiece, on index dial 7, separate several operating angles that need, mix the bushing plate of angle separately, clamped one time just can be processed the hole of multiple directions, especially to comparatively heavy workpiece, reduce the carrying clamping times, reduced labour intensity, improve efficiency, and improved the precision of relative position.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model, to any simple modification, equivalent variations and modification that above embodiment does, all still belongs in the scope of technical solutions of the utility model.
