Abstract
The utility model relates to a positioning and clamping device of a workpiece during drilling, in particular to a positioning and clamping device of the rail support bent plate boreholes, which is used for positioning and clamping the rail support bent plate boreholes in a scraper conveying machine of a coal mine. The rail support bent plate boreholes are produced in batch; by the traditional processing method, the drilling of the workpiece can be finished by combining a clamp, only one workpiece can be assembled and clamped once and two holes at two ends of the bent plate can be finished by assembling and clamping for two times; and in addition, the size and the precision are needed to be checked after one workpoiece is processed and the size of a drilling jig is readjusted. The upper side and the lower side of the middle part of a positioning plate designed by the utility model are respectively provided with a convex positioning surface; two supporting blocks are respectively arranged at symmetrical positions of two sides of the positioning plate; and two workpieces are assembled and clamped once and fixed by a pressure plate and a jack screw and have high size precision without adjusting the size of the drilling jigs, thereby avoiding the phenomenon that the centers of holes at two ends offset, saving the time for adjusting the drilling jigs and repositioning and clamping workpieces and having high production efficiency. The device has simple operation, convenient use and reliable positioning.
Description
Technical field
Positioning clamping device when the utility model relates to Workpiece boring, specifically a kind of rail chair bent plate boring positioning clamping device, the location that is used for the boring of coal mine scraper conveyor rail chair bent plate clamps.
Background technology
Traditional rail chair bent plate drilling method is the processing of group drill jig, and this processing method working (machining) efficiency is too low, does not satisfy the demand of producing.Because of this product lot quantity big, with short production cycle, and combination drill jig processing once can only be processed a part, the hole at workpiece two ends can not time processing, must clamping twice, process the hole of one side, the hole of the processing another side that is installed again again, complex operation, production efficiency is too low, and twice location, the center, hole on two sides on a center line, has not influenced product quality.Owing to be subjected to the restriction of built-up jig, can only use the bolts and nuts locking pressure plate workpiece pressing of small dimension, rigidity is obviously not enough, and workpiece is loosening easily, produces mismachining tolerance, whenever processes one, also needs to check dimensional accuracy, the drill jig size is done readjusted.
Summary of the invention
The purpose of this utility model provides a kind of rail chair bent plate boring positioning clamping device, and to solve the above-mentioned problem that exists, this boring positioning clamping device high efficiency is located reliable, simple to operate, easy to use.
The technical scheme that the utility model adopted is: rail chair bent plate boring positioning clamping device is made up of base plate, gripper shoe, location-plate, bushing plate, drill bushing, pressing plate, nut, bolt, back-up block and jackscrew; Location-plate vertically is weldingly fixed on the base plate, the middle part of location-plate one side respectively has the locating surface of a projection up and down, the both sides symmetric position is welded with 2 back-up blocks respectively, and two limits at two gripper shoe right angles are weldingly fixed on respectively on the opposite side of base plate and location-plate; One end of bushing plate is by being bolted to the upper end of location-plate, and 4 drill bushings are distributed on the bushing plate near on the position of the other end; Pressing plate is fixed on the centre position of location-plate by nuts and bolt, and jackscrew and back-up block are screw-internal thread fit.
The beneficial effects of the utility model are, adopt two the rail chair bent plates that once are installed to process together, the dimensional accuracy height, need not adjust the size of drill jig, the phenomenon of two stomidium off-centrings no longer takes place, and product percent of pass reaches 100%, has saved the time of adjusting lathe or reorientating clamping work pieces, improved efficient, this device can be realized the positioning and clamping and the processing of workpiece fast.
