Description

A kind of Novel bone lamella drilling special fixture
Technical field
The present invention relates to technical field of tooling clamps, specifically a kind of Novel bone lamella drilling special fixture.
Background technology
Internal fixation (bone plate) is one for the treatment of open fracture and the most effective method of comminuted fracture, and hone lamella is the important running stores of this operation.Due to the operating mode that hone lamella is special, the processing of hone lamella bone screw holes also has certain required precision.
The processing of hone lamella bone screw holes, early stage needs drilling to process.The processing method of the processing method that hone lamella bone screw holes is traditional and mechanical component plain bore is similar, needs to rule to each bone screw holes to be processed, get ready, then carries out drilling processing.Above-mentioned work flow is comparatively loaded down with trivial details, and production efficiency is lower, and produce larger impact to the machining accuracy of bone screw holes, the waste product of appearance is more, has a strong impact on the qualification rate of product.In addition, this traditional processing method not only adds the labour intensity of workman, wastes man-hour, and error rate is relatively high.Traditional drilling machining method seriously constrains quality and the production efficiency of product.
Although there are some hone lamella drilling clamps, because location is not good, in process, hone lamella distortion is comparatively large, and add that processing vibration waits impact, Product Precision is not high, and percent defective is still higher.
Summary of the invention
The present invention is directed to existing technical deficiency, there is provided that a kind of working (machining) efficiency is high, positioning precision is higher, the Novel bone lamella drilling special fixture of practicality easy and simple to handle, the problem such as solve that hone lamella drilling process operation is loaded down with trivial details, location is not good, labor strength is comparatively large and percent defective is higher.
The present invention solves the technical scheme that its technical problem takes: described a kind of Novel bone lamella drilling special fixture, and this special fixture comprises frock fixture, location centralising device and clamping device; Described frock fixture comprises base, support and reinforcement, and base is designed with support, and the side of support is designed with reinforcement; Described location centralising device comprises left support nail, rear support nail, adjustable supporting nail, bushing plate, drill bushing, drill bushing fixed head and fixed head screw, the rear side of support is designed with two rear support nails, the left side of support is designed with left support nail, two adjustable supporting nails are designed with in the middle part of base, frame upper is designed with bushing plate, bushing plate is provided with drill bushing, drill bushing is fixed on bushing plate by drill bushing fixed head, the drill bushing fixed head plate bolt that is fixed is fastened on bushing plate, can convenient changing when drill bushing wearing and tearing are larger; Clamping device comprises handle, leading screw, upper holder block and sole piece, and upper holder block is controlled also can move up and down by handle and leading screw and upper holder block one end face and rack inner wall are fitted, and sole piece is fixed on base, and leading screw passes bushing plate and bushing plate is designed with threads of lead screw hole.By support nail (rear support nail, left support nail and adjustable supporting nail) and sole piece, hone lamella to be drilled is positioned, carry out clamping by upper holder block, handle, leading screw and sole piece to hone lamella to be drilled, centering is carried out in the position to be drilled to hone lamella by the drill bushing that is fixed.
The invention has the beneficial effects as follows: this Special Clamps Design has adjustable supporting nail, reduce in process the impact vibrated hone lamella bone screw holes drilling homework precision; This jig Design has multiple drill bushing, can carry out centering to drill position very easily and can carry out drilling operation to multiple hole simultaneously; Production efficiency is higher, and get ready without master worker's line, avoid red tape, percent defective is lower; This cramp assembling and disassembling aspect, simple to operate, manufacturing cost is lower, economical and practical.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described, and exemplary embodiment wherein and explanation are only used for explaining the present invention, but not as a limitation of the invention.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of Novel bone lamella drilling special fixture, this special fixture comprises frock fixture, location centralising device and clamping device; Described frock fixture comprises base 1, support 2 and reinforcement 13, base 1 is designed with support 2, and the side of support 2 is designed with reinforcement 13; Described location centralising device comprises left support nail 3, rear support nail 14, adjustable supporting nail 12, bushing plate 8, drill bushing 9, drill bushing fixed head 10 and fixed head screw 11, the rear side of support 2 is designed with two rear support nails 14, left support nail 3 is designed with on the left of support 2, two adjustable supporting nails 12 are designed with in the middle part of base 1, support 2 upper design has bushing plate 8, bushing plate 8 is provided with drill bushing 9, drill bushing 9 is fixed on bushing plate 8 by drill bushing fixed head 10, drill bushing fixed head 10 plate bolt 11 that is fixed is fastened on bushing plate 8, can convenient changing when drill bushing 9 weares and teares larger; Clamping device comprises handle 6, leading screw 7, upper holder block 4 and sole piece 5, upper holder block 4 is controlled also can move up and down by handle 6 and leading screw 7 and upper holder block 4 one end face and support 2 inwall are fitted, sole piece 5 is fixed on base 1, and leading screw 7 passes bushing plate 8 and bushing plate 8 is designed with threads of lead screw hole.By support nail (rear support nail 14, left support nail 3 and adjustable supporting nail 12) and sole piece 5, hone lamella 15 to be drilled is positioned, carry out clamping by upper holder block 4, handle 6, leading screw 7 and sole piece 5 to hone lamella 15 to be drilled, centering is carried out in the position to be drilled by drill bushing 9 pairs of hone lamellas 15 of being fixed.
