Abstract
The utility model discloses a fixture for clamping and drilling crankshaft flange connecting holes quickly and relates to a tool fixture for metal cold processing, in particular to a drilling fixture for processing a crankshaft of an internal combustion engine. The fixture for clamping and drilling the crankshaft flange connecting holes quickly comprises a fixture base, wherein at least two V-shaped block components are arranged on the fixture base; each V-shaped block component comprises a first V-shaped block and a second V-shaped block; each first V-shaped block is fixedly connected with the fixture base; each second V-shaped block is connected with the fixture base by a positioning device; the fixture base is connected with a first corner oil cylinder and a second corner oil cylinder; the first corner oil cylinder comprises a first pressure plate; the two ends of the first pressure plate of the first corner oil cylinder are arranged above the corresponding first V-shaped block; the second corner oil cylinder comprises a second pressure plate; and the two ends of the second pressure plate of the second corner oil cylinder are arranged above the corresponding first V-shaped block. The fixture has the following advantages that 1, the production efficiency is high; 2, the quality assurance capability is good; and 3, the labor intensity of a worker is reduced.
Description
Technical field
The utility model relates to the cold worked frock clamp of metal, espespecially the boring grab of I. C. engine crankshaft processing.
Background technology
In crankshaft processing technology, the processing of flange end face hole directly affects the quality of internal combustion engine assembling.The many employings of existing end-face hole processing plain radial drilling machine adds with the anchor clamps of drill jig to be processed, and because workpiece needs vertical clamping, labor strength is large; Because the end-face hole number is many, the situation of operation appears leaking in the course of the work easily again; Need ceaselessly change drill bushing, poor reliability during work.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of working (machining) efficiency height, operating aspect, assurance ability strong, the less demanding quick-clamping of employee's technical merit is bored crankshaft flange connecting hole anchor clamps.
The purpose of this utility model is achieved in that quick-clamping bores crankshaft flange connecting hole anchor clamps, comprise clamp base, at least two group V-block assemblies are set on the clamp base, every group of V-block assembly comprises respectively the first V-block and the second V-block, every the first V-block is fixedly connected with clamp base respectively, and every the second V-block is connected with clamp base by positioner respectively; Connect the first corner oil cylinder and the second corner oil cylinder on the described clamp base, the first corner oil cylinder comprises the first pressing plate, and the two ends of the first pressing plate of described the first corner oil cylinder are separately positioned on the top of corresponding the first V-block; The second corner oil cylinder comprises the second pressing plate, and the two ends of the second pressing plate of the second corner oil cylinder are separately positioned on the top of corresponding the second V-block.
Clamp base of the present utility model connects at least two circumferential locating pieces.
During work, the bent axle behind the correct grinding is sling and put down gently in the anchor clamps V-block, the manual rotation workpiece makes bent axle first connecting rod axle journal contact with circumferential locating piece, finishes circumferential location.Gently draw simultaneously workpiece that workpiece thrust gear is contacted with V-block by the end face of flange, finish axial location.Press the clamping button, behind the Workpiece clamping, start procedure, finish the task of boring flange end face hole.
The utlity model has following advantage:
1, production efficiency is high.6 screwed holes and a dowel hole are arranged on the every bent axle, four bent axles of clamped one time, 10 ~ 11 minutes process times, production efficiency is high.
2, assurance ability is strong.Porose position and the depth avoid human factor on the impact of quality by programme-control, and assurance ability is strong.
3, alleviate labor strength.All bent axle laid parallels can adopt the balance crane lifting workpiece, are automatically realized by the corner oil cylinder during clamping work pieces, alleviate labor strength.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model use occasion.
Fig. 3 is the top view of Fig. 2.
Among the figure, 1 clamp base, 2V type block assembly, 2-1 the first V-block, 2-2 the second V-block, 3 first corner oil cylinders, 3-1 the first pressing plate, 4 circumferential locating pieces, 5 second corner oil cylinders, 5-1 the second pressing plate, 6 positioners, 7 bent axles.
The specific embodiment
As shown in Figure 1, 2, 3, quick-clamping bores crankshaft flange connecting hole anchor clamps, comprise clamp base 1, four groups of V-block assemblies 2 are set on the clamp base 1, every group of V-block assembly 2 comprises respectively the first V-block 2-1 and the second V-block 2-2, every the first V-block 2-1 is fixedly connected with clamp base 1 respectively, and every the second V-block 2-2 is connected with clamp base 1 by positioner 6 respectively, and being convenient to change kind is to adjust to use.Two the first corner oil cylinders 3 of connection and two the second corner oil cylinder 5, the first corner oil cylinders 3 comprise the first pressing plate 3-1 on the clamp base 1, and the two ends of the first pressing plate 3-1 of the first corner oil cylinder 3 are separately positioned on the top of corresponding the first V-block 2-1.The second corner oil cylinder 5 comprises the second pressing plate 5-1, and the two ends of the second pressing plate 5-1 of the second corner oil cylinder 5 are separately positioned on the top of corresponding the second V-block 2-2.Clamp base 1 connects four circumferential locating pieces 4, supports as requested the first connecting rod axle journal of bent axle 7, guarantees that benchmark is consistent.Put down gently respectively in the first V-block 2-1 and the second V-block 2-2 at bent axle 7 two ends, and supported the first connecting rod axle journal of bent axle 7 by circumferential locating piece 4.
