Abstract

The utility model relates to a protective drivepipe used in a machine tool, comprising chain rings, clips and coupling heads. The embedding edge of the clip is embedded into a groove at the external surface of the chain ring, then multiple sections of chain rings can be connected together to form a protective drivepipe. The two ends of the protective drivepipe are respectively connected with a coupling head provided with a coupling seat which can be connected with the machine tool. The protective drivepipe of the utility model can overcome the defect of the metal hose (serpentine tube) in the prior art and has the advantages of high strength, convenient installation and maintenance, low cost and uneasy breakage.

Description

Protective drivepipe for the lead-out of machine tool

The utility model is a kind of machine tool accessories, the protection tube that particularly a kind of lathe pipeline is used.

Along with development of modern science and technology, aspect Machine-Tool Control, extensively adopt electronic technology, so the electric appliance circuits on the equipment increases in a large number, such as the logical Digit Control Machine Tool of a Daepori, its circuit just reaches over one hundred, and under many circumstances, requires these circuits to move back and forth at random.Therefore must be to its safekeeping in addition.Also need to be protected such as pipelines such as hydraulic tube, pneumatic tube and dust pipes in addition.The metal hose (being commonly called as coiled pipe) that adopts sheet metal to roll on the lathe is protected at present.The protector manufacturing process complexity of this structure generally can only roll the steel plate of the following thickness of 0.3mm, so mechanical strength is low, during actual the use, often is damaged.And this metal-like hose is an overall structure, so can't carry out partial trim after damaging, has to change again.Will be during replacing the electric wire or the pipeline complete removal that are laid in the protector, very inconvenient.

The purpose of this utility model is to provide a kind of novel protection tube, and it can overcome the deficiency of above-mentioned metal hose.

The purpose of this utility model is achieved in that it is made up of coupling head, chain link and clamp.The transverse shape of chain link can be the annular of circular, square or other different shape.Its outer surface has ring-shaped groove along periphery, and the material of chain link can be selected fiberglass or engineering plastics for use.Clamp is made with sheet metal, and its transverse shape is identical with chain link, for two parts combine.The two ends periphery of clamp has the embedding limit, can embed respectively in the groove of two chain links, and two parts clamp is fixedly connected, being about to two chain links links up, the more piece chain link can be linked by that analogy, can be according to the needs that use length, the quantity of the chain link of determining to link.A coupling head is housed at the two ends of every sleeve pipe.One end transverse shape of coupling head is the same with chain link, and has ring-shaped groove, is linked together by clamp and sleeve pipe, and the other end has connection seat, and connection seat can be made different shape and size according to the connecting mode and the requirement of lathe.

The utility model novel structure, processing technology is simple, cost is low, for more piece combines,, can carry out local replacing therefore if any local damage, and when changing clamp, will wherein electric wire or pipeline not remove, use length arbitrarily to adjust, bring great convenience therefore for use, maintenance.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is the general assembly schematic diagram of a kind of concrete structure of the utility model.

Fig. 2 is the A-A cutaway view among Fig. 1.

Fig. 3 is a kind of front view of chain link of concrete structure.

1 coupling head among the figure, 2 rivets, 3 chain links, clamp on 4,5 times clamps.

With reference to accompanying drawing, chain link 3 is made for the fiberglass material, and its transverse shape is square ring-type, and respectively there is a ring-shaped groove at its outer surface two ends along periphery, and for strengthening the flexibility of protection tube, as shown in Figure 3, ring-shaped groove has the hypotenuse of out of plumb axis.The cross section of the clamp that the steel plate of employing 0.8mm thickness is made is square, and it is combined by last clamp 4 and following clamp 5, and the periphery at two ends all has the embedding limit.Last clamp 4 and following clamp 5 are assembled in the outside of chain link 3, the embedding limit at two ends embeds respectively in the groove of two chain links 3, with self-plugging rivet 2 upper and lower clamp is fixedly connected, being about to two chain links 3 is linked together, by that analogy, can be according to the needs that use length, the chain link 3 of right quantity is linked together, form a root guard sleeve pipe.One end of coupling head 1 is the same with chain link 3, it also is the cross section of square ring-type, and have a ring-shaped groove, and by clamp two coupling heads 1 being linked with the two ends of protection tube respectively, the other end of coupling head 1 has square flange, be drilled with screw hole above, link by screw and lathe, place protection tube to be protected the electric appliance circuits of lathe, because the groove of chain link 3 has hypotenuse, therefore protection tube is flexible fine, can random motion.The probability that chain link 3 damages is very little, and the replacing after the clamp damage is very convenient.Need not whole protection tubes and electric wire dismounting can be carried out modular repair or replacing.
