Abstract
The utility model discloses a fast clamping device of a drill jig in the technical field of machining. The fast clamping device of the drill jig aims at solving the problem that the enterprise production efficiency is reduced owing to time and energy wasting caused by the existing drill jig which is clamped tightly through a compression screw. The fast clamping device of the drill jig comprises a drill plate provided with a plurality of template holes in circumferential direction. A drill bushing is placed inside each template hole in interference fit mode and a plurality of swelling and tightening claws are arranged on a lower end face of the drill plate. A taper swelling and tightening shaft is placed below the drill plate and shares the same axial line with the drill plate, and the taper swelling and tightening shaft and the drill plate are connected together through a pull rod. The lower end of the pull rod penetrates the drill plate and is connected with the taper swelling and tightening shaft in fixed mode, and an eccentric handle is connected with the upper end of the pull rod in a hinge mode through a hinge pin. A circular arc surface sticking close to the upper surface of the drill plate is placed at the lower end of the eccentric handle, and the center of the circle corresponding to the circular arc surface and the shaft center of the hinge pin are arranged in bias mode. The fast clamping device of the drill jig is simple in structure and low in cost, and is applied in the clamping and fastening of workpieces in the drill jig. The fast clamping device of the drill jig has the advantages of being timesaving and labor-saving, high in work efficiency and firm and accurate in locating.
Description
Technical field
The utility model relates to the Machining Technology field, particularly a kind of drill jig quick clamping device.
Background technology
Drill jig is a kind of frock clamp of auxiliary bore hole, is for the positional precision that guarantees boring, improves drilling efficiency, to reduce a kind of device of workman's specification requirement.In machine cut processing, drill jig is used quite extensive, generally is applicable to flange, motor plate, support, hydraulic valve block, cover plate, packing ring, axle and press pressure machine sliding block etc.
In the prior art, a kind of drill jig is arranged, comprise bushing plate, bushing plate circumferentially is distributed with some pattern hole, and interference fit is provided with drill bushing in the pattern hole, and bushing plate axially is provided with some screwed holes for clamping screw is installed.Its weak point is: generally, workpiece to be processed is carried out clamping need to process a plurality of locating holes fixedly the time, easily produce error because skew occurs, affect the drill jig precision; Need between bushing plate and the workpiece to fix by the clamping screw clamping, this just requires must have on the workpiece screwed hole of being convenient to drill jig tension usefulness, limitation in height the scope of application of drill jig; In addition, waste time and energy by the clamping screw workpiece pressing, had a strong impact on enterprises production efficiency.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of simple in structure, with low cost, clamping is time saving and energy saving, high efficiency and locate firm accurately drill jig quick clamping device.
The purpose of this utility model is achieved in that a kind of drill jig quick clamping device, comprises bushing plate, and described bushing plate circumferentially is distributed with some pattern hole, and interference fit is provided with drill bushing in the pattern hole, and the lower surface of described bushing plate is provided with some swelling pawls; The below of bushing plate and with the bushing plate tapering expansion shaft that has been coaxially set, be connected by pull bar between described tapering expansion shaft and the bushing plate, the lower end of described pull bar is passed bushing plate and is fixedly connected with the tapering expansion shaft, the upper end of pull bar is hinged with eccentric handle through bearing pin, described eccentric handle lower end is provided with the arcuate surface of being close to the bushing plate upper surface, and home position corresponding to described arcuate surface setovered mutually with the axle center of bearing pin.
During the utility model work, guarantee that at first eccentric handle is in open mode, check that workpiece to be processed needs bore position whether accurate, then the swelling pawl is placed in the locating hole of workpiece to be processed, pull eccentric handle, utilize the eccentric structure pulling pull bar of eccentric handle, thereby driving the tapering expansion shaft moves upward, force swelling pawl adjacent circumferential expansion, the locking workpiece to be processed is implemented boring along the drill bushing orientation to workpiece to be processed at last.Compared with prior art, the utility model utilizes eccentric structure to replace the clamping screw structure, so that clamping location is more convenient, quick, has reduced workman's labour intensity, Effective Raise Workpiece Machining Accuracy and enterprises production efficiency.
As further improvement of the utility model, the lower end of described pull bar is fixedly connected with by screw thread with the tapering expansion shaft, guarantees that pull bar is connected with the reliable of tapering expansion shaft.
Description of drawings
Fig. 1 is the non-locking working state structure of the utility model schematic diagram.
Fig. 2 is the utility model locking working state structure schematic diagram.
Wherein, 1 bushing plate; 2 drill bushings; 3 swelling pawls; 4 tapering expansion shafts; 5 pull bars; 6 bearing pins; 7 eccentric handle.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of drill jig quick clamping device comprises bushing plate 1, and bushing plate 1 circumferentially is distributed with some pattern hole, and interference fit is provided with drill bushing 2 in the pattern hole, and the lower surface of bushing plate 1 is provided with some swelling pawls 3; The below of bushing plate 1 and with the bushing plate 1 tapering expansion shaft 4 that has been coaxially set, be connected by pull bar 5 between tapering expansion shaft 4 and the bushing plate 1, the lower end of pull bar 5 is passed bushing plate 1 and is fixedly connected with tapering expansion shaft 4, the upper end of pull bar 5 is hinged with eccentric handle 7 through bearing pin 6, eccentric handle 7 lower ends are provided with the arcuate surface of being close to bushing plate 1 upper surface, and home position corresponding to arcuate surface setovered mutually with the axle center of bearing pin 6.In order to guarantee that pull bar 5 is connected with the reliable of tapering expansion shaft 4, the lower end of pull bar 5 and tapering expansion shaft 4 are fixedly connected with by screw thread.
In order to reduce the space hold of eccentric handle 7, avoid collision occurring in eccentric handle 7 work and get loose, preferably so that the axis of eccentric handle 7 during perpendicular to the state of bushing plate 1 upper surface, the utility model is in non-locking duty, as shown in Figure 1; When the axis of eccentric handle 7 paralleled with bushing plate 1 upper surface, the utility model was in the locking duty, as shown in Figure 2.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
