Abstract
The utility model relates to a decorative pattern piece excircle surface boring grab, including the base, it has the shoulder hole to open on the base, and the diameter of shoulder hole from top to bottom reduces gradually, and open the bottom surface of base has the locating hole, and the outer disc of base is opened there is the guiding hole, is equipped with the uide bushing in the guiding hole, pass through the fix with screw in the base with the decorative pattern piece, the outer disc of base is opened has the guiding hole, and the drill bit passes the guiding hole and holes to the outer disc of decorative pattern piece, and the drilling location is accurate, and drilling accuracy is high, saves time, has improved work efficiency and product percent of pass.
Description
Technical field
The utility model relates to clamp art, especially a kind of pattern block outer round surface boring grab.
Background technology
In existing technology, on cylindrical, boring is undertaken processing by the method for scribing by bench worker, but the restriction due to precision of ruling makes the position degree in hole be difficult to ensure, and working strength is larger, be only suitable for Single unit job lot production, so traditional processing method can not meet production in enormous quantities, bores multiple holes technical requirement on cylindrical.And not easily clamp due to cylindrical work, process easily moves axially or circumference is rolled, make boring location inaccurate, repeatedly need adjust bore position, and then make the consuming time longer of boring, cause work efficiency drop, and also can increase artificial labour intensity, simultaneously because borehole accuracy is low, crudy is wayward, also can cause the appearance of a large amount of substandard products and waste product, processing cost is higher.
Utility model content
The technical problems to be solved in the utility model is: when holing on cylindrical to solve, boring location is inaccurate, borehole accuracy is low, labour intensity is large and ineffective problem, there is provided a kind of accurate positioning, borehole accuracy high, and can increase work efficiency and the pattern block outer round surface boring grab of crudy.
The utility model solves the technical scheme that its technical problem adopts: a kind of pattern block outer round surface boring grab, comprise base, described base has shoulder hole, the diameter of described shoulder hole from top to bottom reduces gradually, the bottom surface of described base has locating hole, the periphery of described base has pilot hole, is provided with fairlead in described pilot hole.
Concrete, the quantity of described pilot hole is 18, and described pilot hole is evenly distributed on the periphery of base.
Pattern block is put into the shoulder hole of base, the bottom surface of pattern block has the screwed hole matched with the locating hole of base end face, is fixed in base by screw by pattern block, namely completes the location of pattern block; During boring, drill bit is inner from pilot hole inserted base, and drill bit can be holed at the periphery of pattern block, and do not need to adjust position, save the plenty of time, accurate positioning, borehole accuracy is high, improves operating efficiency and product percent of pass.
The beneficial effects of the utility model are, are fixed by screws in by pattern block in base, and base periphery has pilot hole, drill bit is holed through the periphery of pilot hole to pattern block, boring accurate positioning, and borehole accuracy is high, save time, improve operating efficiency and product percent of pass.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of utility model works state;
Fig. 2 is structural representation of the present utility model.
In figure: 1. base, 2. locating hole, 3. pilot hole, 4. fairlead, 5. pattern block.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of pattern block outer round surface boring grab as illustrated in fig. 1 and 2, comprise base 1, described base 1 has shoulder hole, the diameter of described shoulder hole from top to bottom reduces gradually, the bottom surface of described base 1 has locating hole 42, and the periphery of described base 1 has pilot hole 3, and the quantity of described pilot hole 3 is 18, described pilot hole 3 is evenly distributed on the periphery of base 1, is provided with fairlead in described pilot hole 3.
Pattern block 5 is put into the shoulder hole of base 1, the bottom surface of pattern block 5 has the screwed hole matched with the locating hole 42 of base 1 bottom surface, is fixed in base 1, namely completes the location of pattern block 5 by screw by pattern block 5; During boring, drill bit is inner from pilot hole 3 inserted base 1, and drill bit can be holed at the periphery of pattern block 5, and do not need to adjust position, save the plenty of time, accurate positioning, borehole accuracy is high, improves operating efficiency and product percent of pass.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
