Abstract

The utility model discloses a dish type external member boring grab, it includes the base, is equipped with in the top surface of base and supplies to wait to process the columnar structure that the external member installation is taken one's place, is equipped with the bushing plate in the top of columnar structure side, is equipped with the screw rod in the bushing plate center, and the screw rod is formed with the free end along the axial extension qieyu base both sides of columnar structure, has a nut I in the end fixing of screw rod one end, has set gradually snap washer, nut II in the screw rod other end, wherein, is equipped with the drill bushing on the bushing plate, and beneficial effect is: wait to process workpiece setting and accomplish the back, through the drill bushing on the bushing plate can be with the processing of driling to the work piece, anchor clamps compact structure, workpiece setting is convenient, the machining precision height.

Description

Dish class external member boring grab
Technical field
This practicality relates to technical field of tooling clamps, is specially a kind of dish class external member boring grab.
Background technology
Fixture is be used for fixing processing object in machine-building process, make it to occupy tram, to accept the device processed or detect, at present, what dish class external member was holed usually will by radial drilling machine, and conventional brace is when Drilling operation, need repeatedly to dismantle workpiece, working (machining) efficiency is low, and the concentricity simultaneously machined between rear each hole is large, and machining accuracy needs to be improved further.
Summary of the invention
For the problems referred to above, this practicality provides a kind of dish class external member boring grab, and its main technical scheme is as follows:
Dish class external member boring grab, it comprises base (1), end face in base (1) is provided with the column structure (11) supplying external member to be processed (2) installation in position, bushing plate (4) is provided with in the top side of column structure (11), screw rod (3) is provided with in bushing plate (4) center, described screw rod (3) extends along the axis of column structure (11) and is formed with free end in base (1) both sides, end winding support in screw rod (3) low level one end has nut I (5), open washer (7) is disposed with in screw rod (3) high-order one end, nut II (6),
Wherein, described bushing plate (4) is at least provided with a drill bushing (41), the top side of described column structure (11) is provided with alignment pin rod (8), and the bottom surface of described alignment pin rod (8) correspondence position bushing plate (4) is provided with pin-and-hole.
As preferably, further, described drill bushing (41) be set to three and equal circumference apart from distribution.
As preferably, further, described bushing plate (4) forms centre bore (42), and the screw rod (3) of described centre bore (42) inner side is fixed with sleeve member (9).
As preferably, further, the bottom center of described base (1) forms concavity portion (12).
The beneficial effect of this practicality is: after workpiece to be processed clamping completes, by bushing plate drill bushing both can carry out Drilling operation to workpiece, clamp structure is compact, and trade union college is convenient, and machining accuracy is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment mid-game class external member boring grab
Detailed description of the invention
In order to make the technological means of this practicality, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth this practicality further.
See Fig. 1, dish class external member boring grab, it comprises base 1, end face in base 1 is provided with the column structure 11 supplying external member 2 installation in position to be processed, be provided with bushing plate 4 in the top side of column structure 11, be provided with screw rod 3 in bushing plate 4 center, screw rod 3 extends along the axis of column structure 11 and is formed with free end in base 1 both sides, end winding support in screw rod 3 low level one end has nut I 5, sets gradually open washer 7 in the high-order one end of screw rod 3, has nut II 6; Wherein, bushing plate 4 is at least provided with a drill bushing 41, drill bushing 41 also can be that equal circumference is apart from two, three that arrange, add to prevent bushing plate 4 and be subjected to displacement man-hour, improve machining accuracy, be provided with alignment pin rod 8 in the top side of column structure 11, the bottom surface of alignment pin rod 8 correspondence position bushing plates 4 is provided with pin-and-hole.The installation steps of workpiece are, add and man-hour the column structure 11 of external member 2 to be processed along base 1 are inserted in, and bushing plate 4 is by installation in position behind alignment pin rod 8 location, and be loaded on part open washer 7, finally screw with nut II 6, clamping is complete.
As preferably, the drill bushing 41 in the present embodiment be set to three and equal circumference apart from distribution.
For the ease of installing drill template 4, improve machining accuracy, bushing plate 4 forms centre bore 42 simultaneously, and the screw rod 3 in centre bore is fixed with sleeve member 9.
For ensureing the planarization of base 1 bottom surface, the bottom center of base 1 forms concavity portion 12, is positioned at concavity portion 12 after the nut I 5 of screw rod 3 one end is in place.
The foregoing is only the preferred embodiment of this practicality; the protection domain of this practicality is not limited in above-mentioned embodiment; every technical scheme belonging to this practical principle all belongs to the protection domain of this practicality; for a person skilled in the art; the some improvement carried out under the prerequisite of principle not departing from this practicality, these improve the protection domain that also should be considered as this practicality.
