Abstract
The utility model relates to a screw rod mechanism with a protective sleeve. The screw rod mechanism comprises a screw rod and ball bearings which support two ends of the screw rod. The screw rod mechanism with the protective sleeve is characterized in that the protective sleeve is placed on an outer circle of the screw rod. The screw rod mechanism with the protective sleeve has the advantages that the screw rod protective sleeve is a sleeve which can be retractable with increasing or reducing of a gap of a double-end-milling grooving machine, and the screw rod protective sleeve protects the screw rod and quick-wear parts of whole equipment. Articles such as clothes are prevented from being wound into the screw rod and damaging the ball bearings of the screw rod. The problems that thick rust is produced on the surface of the screw rod caused by oxidation for the screw rod is exposed in the air for a long time and the thick rust is not easy to polish are solved, and greasy filth is produced when lubricating grease is coated on the screw rod. Foreign matters such as dust sticked on the surface of the screw rod when products are cut are removed. Retention time of the lubricating grease coated on the surface of the screw rod can be prolonged, and correspondingly, maintenance period can be prolonged. The dust and other foreign matters around and on the screw rod can be cleaned and swept easily, and in the process of sweeping, no danger exists and sweeping speed is fast.
Description
Technical field
The utility model belongs to the lead screw transmission parts, relates in particular to a kind of screw mechanism with protective sleeve.
Background technology
In process of production, the two-ends milling machine groover is carrying out to sheet material in the work of kerve, produce more dust, although powerful precipitron is arranged to be removed, but after all have small part dust thing and fly to device external, so can be bonded at above the lubricating grease of feed screw surface-coated, long time integration can be piled into soil block at last by dust, when equipment is remodeled because of product, when needing to change the sheet material width, then will adjust the spacing of feed screw, can be involved in leading screw ball bearing inside this moment with the dust above the leading screw or soil block, causes the ball of leading screw ball bearing inside stuck, even with the bearing of equipment other parts, leading screw, linear bearing etc. part does great damage because the strength of leading screw carrying device walking is unequal, and repair and bother very much loaded down with trivial detailsly, the spare part cycle is longer, causes damp production to carry out.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of screw mechanism with protective sleeve to be provided, solve leading screw because being exposed to for a long time in the air, producing the situation generation of rusty stain and dust foreign matter cause damage of equipment.
The utility model is achieved through the following technical solutions for achieving the above object, and a kind of screw mechanism with protective sleeve comprises leading screw and the ball bearing that is bearing in the leading screw two ends, and it is characterized in that: described leading screw cylindrical is provided with protective sleeve.
Described protective sleeve shape is the organ type protective sleeve of can automatic telescopic regulating.
The head and the tail two ends of described protective sleeve are provided with fixedly larynx hoop.
Be provided with several supporting steel wire rings in the described protective sleeve, described supporting steel wire ring adopts plastics or metal material to make.
Described protective sleeve adopts protective cloth or oil resistant rubber or plastic material to make.
Beneficial effect: the sleeve pipe that the leading screw protective sleeve can stretch along with increase or the minimizing of the spacing of two-ends milling machine groover, to the protection of leading screw and Whole Equipment consumable accessory.Prevent that the article such as clothing are wound into leading screw, the leading screw ball bearing is sternly bad; Solve the leading screw surface because being exposed to for a long time the thicker rusty stain of oxidation generation in the air, and be not easy to be polished, and coat in the situation of lubricating grease and produce greasy filth; The foreign matters such as dust that stay after the product that solution leading screw surface is stained with cuts; Can prolong the lubricating grease retention time of leading screw surface-coated, can prolong accordingly maintenance period; Dust foreign matters on leading screw periphery and the leading screw etc. are easily cleared up and cleaning, and nothing is dangerous and quick in the process of cleaning.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, leading screw, 2, ball bearing, 3, protective sleeve, 4, fixing larynx hoop.
The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that foundation the utility model provides: see accompanying drawing for details, a kind of screw mechanism with protective sleeve comprises leading screw 1 and is bearing in the ball bearing 2 at leading screw two ends that described leading screw cylindrical is provided with protective sleeve 3.Described protective sleeve shape is the organ type protective sleeve of can automatic telescopic regulating.The head and the tail two ends of described protective sleeve are provided with fixedly larynx hoop 4.Be provided with several supporting steel wire rings in the described protective sleeve, described supporting steel wire ring adopts plastics or metal material to make.Described protective sleeve adopts protective cloth or oil resistant rubber or plastic material to make.
The course of work
Leading screw is disassembled from equipment, the screw set at leading screw ball bearing two ends is loaded onto sleeve pipe, and the sleeve pipe two ends are fixed on above the fixing bearing of leading screw, avoid sleeve pipe and leading screw to rotate simultaneously, then according to assemble sequence leading screw is installed.Protective sleeve can carry out automatic telescopic and regulate along with the increase of the pitch of feed of leading screw and minimizing.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment does.
