Abstract
This utility model is standard section main limb bar drill hole tool, including base plate, base plate is rectangle strip, be arranged over processing plate, base plate and the processing plate of base plate are connected by minor face side plate, the space that intermediate formation coordinates with workpiece size, base plate and processing plate are provided with corresponding 3 boring, described boring is provided with cushion block, and it is bittiness that described cushion block is provided with limit convex at two ends, and described minor face side plate is provided with spacing hole；Described processing plate is provided with big screw.Utilize that limit convex is bittiness, top and side bolt fixing so that more firm during boring, it is ensured that the positioning precision of boring, lay the first stone for subsequent operation.
Description
Technical field
This utility model relates to crane and produces apparatus field, is specifically related to standard section main limb bar drill hole tool.
Background technology
The standard section main zeugopodium of crane usually achieves a fixed connection by bolt, first to hole on standard section main zeugopodium connecting plate before connection, traditional drilling and positioning method is to hold pen and chi artificially does mark for dowel hold at standard section main zeugopodium, although it is easy to operate, but the positioning precision of boring is poor, brill is wrong, bore partially, bore askew situation happens occasionally, and the progress that not only impact normally produces is also easy to cause later stage safety problem；Although have has fixing device, but fixed effect is the best, it is impossible to ensure the processing conditions of boring；Some manufacturing costs are higher, and structure is complicated, difficult in maintenance and maintenance cost is higher, be unsuitable for the small lot processing of boring, and service life is shorter.Therefore it provides a kind of stabilized structure, easy to operate, manufacture maintenance cost low, durable in use, the crane end carriage fixing device for drilling with preferable fixed effect is very important.
Utility model content
The technical problems to be solved in the utility model is to provide standard section main limb bar drill hole tool, solves the problem that prior art fixed effect is the best.
Standard section main limb bar drill hole tool, including base plate, base plate is rectangle strip, be arranged over processing plate, base plate and the processing plate of base plate are connected by minor face side plate, the space that intermediate formation coordinates with workpiece size, base plate and processing plate are provided with corresponding 3 boring, described boring is provided with cushion block, and it is bittiness that described cushion block is provided with limit convex at two ends, and described minor face side plate is provided with spacing hole；Described processing plate is provided with big screw.
This utility model further improvement project is, described spacing hole has 4, supporting with bolt.
This utility model further improvement project is that described cushion block is arranged on central bore.
This utility model further improvement project is, described big screw is positioned on front side of boring.
This utility model compared with prior art, has the advantage that
Utilize that limit convex is bittiness, top and side bolt fixing so that more firm during boring, it is ensured that the positioning precision of boring, lay the first stone for subsequent operation.
With embodiment, this utility model is described further below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model standard section main limb bar drill hole tool.
Wherein: 1-base plate, 2-process plate, 3-boring, 4-cushion block, 5-limit convex is bittiness, the big screw of 6-spacing hole, 7-.
Detailed description of the invention
The bar drill hole tool of this utility model standard section main limb shown in Fig. 1, including base plate 1, base plate 1 is rectangle strip, base plate 1 be arranged over process plate 2, base plate 1 and processing plate 2 are connected by minor face side plate, the space that intermediate formation coordinates with workpiece size, and base plate 1 and processing plate 2 are provided with corresponding 3 boring 3, described boring 3 is provided with cushion block 4, and described cushion block 4 is arranged on central bore 3；Described cushion block 4 is provided with limit convex bittiness 5 at two ends, and described minor face side plate is provided with spacing hole 6；Described processing plate 2 is provided with big screw 7, and described big screw 7 is positioned on front side of boring 3；Described spacing hole 6 has 4, supporting with bolt.
During use, workpiece is placed on the cushion block 4 on base plate 1, props up limit convex bittiness 5, then the big screw 7 on the spacing hole 6 on minor face side plate and processing plate is tightened fixing, hole.
Above-described is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, on the premise of creating design without departing from this utility model; can also make some deformation and improvement, these broadly fall into protection domain of the present utility model.
