Abstract
The utility model discloses an elasticity lathe chuck dop, including the barrel of cylindricality, the front end of the barrel outside has the inclined plane shirt rim structure of outdiffusion, and has evenly laid a plurality of openings on the barrel, and the opening radially runs through the inside and outside wall of barrel, the arc radial hole at open -ended both sides border axial extension to barrel rear portion and with radial hole's opening part tandem, the rear portion is for the appear cavity of structure of pylon in the barrel, the barrel is provided with enclasping mechanism outward. Opening through evenly laying divides equally the barrel front end for a plurality of fan -shaped cylinder structures, through each fan -shaped cylinder structure radial movement of enclasping mechanism messenger, makes the internal diameter of barrel dwindle, with shock absorber sleeve pipe chucking, and simple structure, equitable, easy and simple to handle, labour saving and time saving, efficient, the centre gripping is stable, and the turning quality is secure.
Description
Technical field
The utility model relates to shock absorber tubulation production equipment technical field, particularly relates to a kind of elasticity lathe chuck dop for clamping shock absorber sleeve pipe.
Background technology
In the tubing process of manufacture in shock absorber tubulation workshop, after tubing blocks by given size, tubing clamping is needed to be fixed on the chuck of lathe, carry out turnery processing further, and traditional lathe chuck is generally scroll chuck, by moving radially of three movable chucks, Workpiece clamping is realized to locate, its weak point existed is: 1) need manually to adopt spanner to carry out turning clamp operation, labor strength is large, and production efficiency is low, time-consuming, effort, and it is when changing workpiece, also very inconvenient; 2) owing to adopting manual clamping, dynamics is difficult to stability contorting, and three movable chucks easily cause clamping pipe deformations, add an examination of bad, thus causes clamping effect poor, and then causes the axiality of product after car uneven, and percent defective is high, affects product quality.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of structure simple, easy and simple to handle, saves time, laborsaving, effective, and the elasticity lathe chuck dop of effective guarantee product quality.
The technical scheme adopted for realizing the purpose of this utility model is: this chuck dop comprises the cylindrical shell of cylindricality, the front end outer side of cylindrical shell has the inclined-plane skirt border structure to external diffusion, and cylindrical shell is evenly laid with multiple opening, opening radial direction runs through the inside and outside wall of cylindrical shell, the dual-side of opening extend to vertically cylindrical shell rear portion arc radial direction through hole and with the opening part tandem of radial direction through hole, in cylindrical shell, rear portion is the cavity of pillar base type structure, and cylindrical shell is outside equipped with hold-fast body.
Described hold-fast body is the collar.
The utility model has following beneficial effect:
1) barrel front end is divided into multiple fan-shaped cylinder structure by the opening evenly laid by chuck dop, by hold-fast body, each fan-shaped cylinder structure is held tightly, each fan-shaped cylinder structure moves radially, the internal diameter of cylindrical shell is reduced, because the casing size of the same production line producing shock absorber is certain, adopt the above-mentioned chuck dop suitable with casing size, fan-shaped cylinder structure only needs to move radially less distance and shock absorber sleeve pipe can be clamped, therefore, opened gap on cylindrical shell is also smaller, and when clamping, barrel front end inwall almost contacts with shock absorber bushing outer surface completely, contact surface is large, uniform force, can effectively avoid shock absorber casing deformation, and barrel front end radial direction has certain distance, can the axiality of effective guarantee shock absorber sleeve pipe, improve turning quality, improve product percent of pass.
2) hold-fast body adopts the collar, and along cylindrical shell axial advance, what can realize dop effectively stablizes clamping work, and the propelling of the collar easily adopts cylinder or hydraulic cylinder to drive, and convenient operation controls, and saves time, laborsaving, efficiency is high.
3) the utility model is simple and reasonable for structure, easy and simple to handle, time saving and energy saving, efficiency is high, and clamping is stable, and turning quality is secure.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the cross-sectional view of the utility model cylindrical shell;
Fig. 2 is the end face structure schematic diagram of the utility model cylindrical shell;
Structural representation when Fig. 3 is the utility model use.
Detailed description of the invention
As Figure 1-3: elasticity lathe chuck dop of the present utility model, comprise the cylindrical shell 2 of cylindricality, the front end outer side of cylindrical shell 2 has the inclined-plane skirt border structure 3 to external diffusion, and cylindrical shell 2 is evenly laid with multiple opening 1, opening 1 radial direction runs through the inside and outside wall of cylindrical shell 2, the dual-side of opening 1 extend to vertically cylindrical shell 2 rear portion arc radial direction through hole 4 and with the opening part tandem of radial direction through hole 4, by the opening 1 evenly laid, cylindrical shell 2 front end is divided into multiple fan-shaped cylinder structure, fan-shaped cylinder inner structural wall forms a circular configuration encircled; In cylindrical shell 2, rear portion is the cavity 5 of pillar base type structure, and cylindrical shell 2 is outside equipped with hold-fast body, as long as described hold-fast body is a circular ring 6 or other inwalls is the structural member of circular configuration, or adopts sleeve also can; The both sides of the collar 6 are provided with symmetrical push-pull arm 7, push-pull arm 7 is provided with driving mechanism, driving mechanism adopts cylinder or hydraulic cylinder, only need the front-rear reciprocation movement realizing hold-fast body, driving mechanism is controlled by controller or control button, cylindrical shell 2 is fixed on dop seat 8 by the cavity 5 of its inside is sheathed, dop seat 8 can be threaded with cylindrical shell 2, or to be fixed by rivet or pin and spacingly also can, dop seat 8 can adopt cylindrical structure, is convenient to the longitudinal direction of workpiece deeply.
During turning operation, shock absorber sleeve pipe being inserted in cylindrical shell 2, by starting driving mechanism, hold-fast body being pushed ahead, act on the inclined-plane skirt border structure 3 of cylindrical shell 2, the fan-shaped cylinder structure of its front end can be realized radially-inwardly to compress, thus by shock absorber sleeve pipe clamping stable holding, simultaneously, the radial structure of cylindrical shell 2 front end ensures the axiality of shock absorber sleeve pipe, ensure product turning quality, improve product percent of pass, product qualification rate reaching more than 99%.When more changing jobs, again start driving mechanism, hold-fast body is retracted, the fan-shaped cylinder structure of cylindrical shell 2 front end can reply position by appliance for releasing single, unclamps shock absorber sleeve pipe, is taken off by shock absorber sleeve pipe good for car, change next shock absorber sleeve pipe to be processed, next circulation process can be entered, operate very easy, efficiency is high, the turnery processing time of single shock absorber sleeve pipe effectively can save 2/3rds.
The technical solution of the utility model is not limited in the scope of the utility model embodiment.The technology contents of the not detailed description of the utility model is known technology.
