Abstract
The utility model discloses a special compound tool which is formed by sequentially connecting of a first tool bit portion (2), a second tool bit portion (5) and a tool handle portion (6). The diameter of the first tool bit portion (2) is smaller than that of the second tool bit portion (5), three arc-shaped right-angle grooves (4) are evenly distributed in a tool bit portion which is formed by the first tool bit portion (2) and the second tool bit portion (5), boring blades (1) are fixed on the three arc-shaped right-angle grooves (4) of the first tool bit portion (2), chamfering blades (3) are fixed on one of the three arc-shaped right-angle grooves (4) of the second tool bit portion (5), and ream end face blades (7) are fixed on one of the three arc-shaped right-angle grooves (4) of the second tool bit portion (5). With the structure, the special compound tool has the advantages of being simple and reasonable in structure, rapid in machining speed, good in quality, low in cost, high in product percent of pass, capable of being machined and completed once.
Description
Technical field
The utility model relates to a kind of compound tool, particularly a kind of Special compound tool that the radiator fin connecting hole is carried out bore hole, spot facing and the moulding of interior chamfering time processing.
Background technology
The die casting aluminium radiator is to be formed by fixedly connecting by multi-disc die casting aluminium radiator fin, two die casting aluminium radiator fin connecting holes connect by connector, the flatness of radiator and sealing property all have direct relation with connecting hole, and be therefore higher to machining accuracy and the requirement of connecting hole.Present die casting aluminium radiator fin connecting hole processing was undertaken by bore hole, chamfering, three steps of spot facing, on the one hand operator's technical merit was had relatively high expectations, and is higher to performance and the functional requirement of process equipment on the other hand, the crudy of guarantee product; In product processing, exist that the finished product rate is low, processing cost is high, process velocity is slow, production efficiency is low, can't satisfy the problems such as requirements of mass production; The opportunity that so not only affects the competitiveness of product in market and dominate the market, and directly affect the economic benefit of enterprise and the power of enterprise development.For this reason, many manufacturers and knowledgeable people have carried out R and D, but desirable solution is not arranged so far.
Summary of the invention
For overcoming the defects that exists in the existing die casting aluminium radiator fin connecting hole process, the purpose of this utility model provides a kind of simple and reasonable, process velocity is fast, quality good, cost is low, product percent of pass is high Special compound tool.
The utility model solves the problems of the technologies described above the technical scheme that adopts, it is formed by the first cutter head section, the second cutter head section, handle of a knife section three parts successively disjunctor, the diameter of the first cutter head section is less than the second cutter head section, be evenly equipped with three arc trough with straight angle in the cutter head section that described the first cutter head section and the second cutter head section form, three arc trough with straight angle in the first cutter head section are fixed with the bore hole blade, are fixed with chamfering blade at one of them arc trough with straight angle of the second cutter head section.
One of them arc trough with straight angle in the second cutter head section is fixed with the spot facing blade.
After adopting said structure, compared with prior art have the following advantages and effect, the one, machining accuracy is high, because bore hole, spot facing and chamfering are once finished, can guarantee the concentricity of radiator fin connecting hole processing, can guarantee simultaneously the uniformity of finished surface precision and product, good product quality, qualification rate is high.The 2nd, production efficiency is high, because the time processing moulding has reduced the secondary process times such as tool changing, tool setting, has greatly accelerated process velocity.The 3rd, production cost is low, and low to the requirement of workman's technical merit, tissue is produced in enormous quantities convenient, can reduce the input of station and process equipment.The 4th, cutter is easy to manufacture, can manufacture, and cutter is made simple and convenient, can reuse by the transposing blade, and the cutter use cost is low.

1 bore hole blade wherein, 2 first cutter head sections, 3 chamfering blades, 4 arc trough with straight angle, 5 second cutter head sections, 6 handle of a knife sections, 7 spot facing blades.
The specific embodiment
Fig. 1, Fig. 2 and shown in Figure 3, specific embodiments for the utility model processing heat radiator sheet connecting hole Special compound tool, formed by the first cutter head section 2, the second cutter head section 5, handle of a knife section 6 three parts successively disjunctor, the diameter of the first cutter head section 2 is less than the second cutter head section 5, be evenly equipped with three arc trough with straight angle 4 in the cutter head section that described the first cutter head section 2 and the second cutter head section 5 form, three arc trough with straight angle 4 in the first cutter head section 2 are fixed with bore hole blade 1, are fixed with chamfering blade 3 at one of them arc trough with straight angle 4 of the second cutter head section 5.One of them arc trough with straight angle 4 in the second cutter head section 5 is fixed with spot facing blade 7.Add man-hour, utilize 1 pair of connecting hole of bore hole blade of the first cutter head section 2 to carry out bore hole, when tool feeding to the regulation the degree of depth time, utilize synchronously 7 pairs of connecting holes of chamfering blade 3 and spot facing blade to carry out chamfering and spot facing, bore hole, chamfering and spot facing process at one time.
Claims (2)
1. Special compound tool, by the first cutter head section (2), the second cutter head section (5), handle of a knife section (6) three parts successively disjunctor form, the diameter of the first cutter head section (2) is less than the second cutter head section (5), it is characterized in that: be evenly equipped with three arc trough with straight angle (4) in the cutter head section that described the first cutter head section (2) and the second cutter head section (5) form, three arc trough with straight angle (4) in the first cutter head section (2) are fixed with bore hole blade (1), are fixed with chamfering blade (3) at one of them arc trough with straight angle (4) of the second cutter head section (5).
