Abstract
The utility model provides a small-screw follower rest sleeve structure which comprises a main screw, wherein the top of the main screw is connected with an upper connection block on main screw gear hobbing processing equipment through a small screw, a small-screw follower rest sleeve is arranged between the small screw and the upper connection block and comprises a sleeve body, a top piece is connected with the sleeve body through bolts, and a sleeve hole is formed in the middle of the sleeve body and in the middle of the top piece. The small-screw follower rest sleeve structure is simple in structure and convenient to use, and can fix the main screw during machining, so that the machining quality of the main screw is improved.
Description
Technical field
The utility model belongs to extruder field, specifically a kind of small screw follow-rest nested structure.
Background technology
Packaging industry is thriving at present, and plastic packets has been dressed up an indispensable part in our life.The plastics package of many toys all is stamped to form by plastic plate.At first plastic plate processing need plastics or glass particle are carried out charging and extrude, and generally extrudes by extruder.The driving screw of extruder is the key position of extruder, when producing driving screw, general is all that driving screw to be processed is placed on process equipment, there is no fixture between driving screw top and process equipment, the position of driving screw is stable not like this, in machining screw, producing slight rocking will affect crudy, causes screw thread inhomogeneous.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of small screw follow-rest nested structure.
A kind of small screw follow-rest nested structure, it is characterized in that comprising driving screw, the top of driving screw is connected with the upper contiguous block of driving screw hobbing equipment by small screw, be provided with small screw follow-rest cover between small screw and upper contiguous block, described small screw follow-rest cover comprises body, the upper end of described body is provided with top flat, and described top flat and described body are connected by screw, and is provided with trepanning in the middle of described body and in the middle of top flat.
Described a kind of small screw follow-rest nested structure, the cross section that it is characterized in that described body is circular, the longitudinal section is the T font.
Described a kind of small screw follow-rest nested structure is characterized in that described top flat is circular.
Described a kind of small screw follow-rest nested structure is characterized in that described trepanning is circular, and the concentric setting identical with cover hole size on top flat of the trepanning on body.
Described a kind of small screw follow-rest nested structure is characterized in that described screw has 4, is symmetrically distributed on the circumference of top flat and body.
Described a kind of small screw follow-rest nested structure is characterized in that being provided with side opening in the side of described trepanning.
Described a kind of small screw follow-rest nested structure, the thickness that it is characterized in that described top flat is 0.2-1cm.
Small screw follow-rest nested structure of the present utility model, simple in structure, easy to use, can play fixation to driving screw when the processing driving screw, improved the crudy of driving screw.

Fig. 2 is the use view of small screw follow-rest nested structure of the present utility model;
In figure, 1-top flat; 2-body; 3-trepanning; 4-screw; 5-side opening; 6-driving screw; 7-small screw; 8-follow-rest cover; 9-upper contiguous block.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As depicted in figs. 1 and 2, a kind of small screw follow-rest nested structure of the present utility model, comprise driving screw, the top of driving screw is connected with the upper contiguous block of driving screw hobbing equipment by small screw, be provided with small screw follow-rest cover between small screw and upper contiguous block, small screw follow-rest cover comprises body, and the upper end of body is provided with top flat, top flat and body are symmetrically distributed in by 4 the screw that top flat is connected with body on circumference and are connected, and make whole follow-rest nested structure more firm; Be provided with trepanning in the middle of body and in the middle of top flat.The cross section of body is circular, and the longitudinal section is the T font, and top flat is also circular, and thickness is 0.5cm, and trepanning is also circular, and the concentric setting identical with cover hole size on top flat of the trepanning on body.The side of trepanning is provided with side opening, can add lubricating oil from side opening, and the follow-rest cover is played lubrication, prevents device damage.During work, the follow-rest cover is enclosed within on small screw, and the follow-rest cover is connected with upper contiguous block, by small screw, driving screw is played fixing effect, guarantees the driving screw position stability, can not produce and rock, and has guaranteed crudy.
The above is only preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of doing within spirit of the present utility model and principle, is equal to and replaces and improvement etc., within all being included in protection domain of the present utility model.
