Abstract
The utility model discloses a rough turning fixture for sleeve parts. A contraction gap is formed in the excircle of a cone-shaped expansion sleeve (3) evenly and axially along the circumference, the cone-shaped expansion sleeve (3) is installed on the outer wall of a cone-shaped mandrel (1) through a spring (4) along the axial direction in a sleeved mode, a pull rod (2) penetrates through central holes of the cone-shaped mandrel (1), the spring (4) and the cone-shaped expansion sleeve (3), a screw nut (5) is fixed at one end of the pull rod (2), and the cone-shaped expansion sleeve (3) expands and contracts under the action of mutually matched conical surfaces in the radial direction. The rough turning fixture for the sleeve parts is simple in structure, and convenient to operate. The inner conical surface of the cone-shaped expansion sleeve and the outer conical surface of the cone-shaped mandrel are matched, so that the cone-shaped expansion sleeve can move axially along the axis of the cone-shaped mandrel. Labor intensity of workers is reduced, quality of machining products is ensured, production efficiency is promoted, and the rough turning fixture for the sleeve parts is suitable for quantity production.
Description
Technical field
The utility model relates to the rough turning processing of sleeve part, particularly is applicable to the cylinder jacket rough turning clamp for machining of producing in enormous quantities.
Background technology
Present sleeve part, the rough turning processing of the cylinder jacket part of particularly producing in enormous quantities all is to use as anchor clamps with scroll chuck.Because the design feature of the part of sleeve type itself, namely the diameter of axle is large than very, and clamping force was larger when three-jaw clamped, and the while, cutting force was large in the time of processing owing to the parts such as cylinder sleeve are longer, and clamping force can not meet the demands, all need to be in the afterbody of part supplemental support in addition.So both increase operating personnel's physical demands, also reduced efficiency.Again because the professional production of the part such as cylinder jacket all is to produce in enormous quantities, if clamping three-jaw frequently can not guarantee the quality of product.
Summary of the invention
The purpose of this utility model is: a kind of sleeve part rough turning clamp for machining is provided, and clamp structure is simple, and is easy to use, guarantees the converted products quality, enhances productivity, and is applicable to mass production.
The technical method that its technical problem that solves the utility model adopts is: these anchor clamps comprise the taper mandrel, pull bar, the taper ringfeder, spring and nut, the cylindrical of taper ringfeder is axially opened shrinkage joint along even circumferential, the taper ringfeder is contained on the outer wall of taper mandrel along axis direction through spring housing, pull bar passes the taper mandrel, the centre bore of spring and taper ringfeder, one end hold-down nut of pull bar, the taper ringfeder is done radially harmomegathus under the effect of the conical surface that cooperatively interacts, taper ringfeder spreading radially when the taper ringfeder cooperates the conical surface to be moved to the left along the axis direction of taper mandrel, taper ringfeder radial contraction when the taper ringfeder cooperates the conical surface to move right along the axis direction of taper mandrel.
In use, cylinder jacket to be processed is positioned on the taper ringfeder, pull bar moves to left under external force, the nut drive taper ringfeder that screws with pull bar moves to left, taper ringfeder spreading radially on the conical surface that cooperatively interacts, thereby the tensioner cylinder jacket so just forms the cylinder cover inner hole positioning states, and expanding force is as clamping power simultaneously; When the cylinder jacket completion of processing, pull bar moves to right under external force, compressed spring elastic recovery after pressure is disengaged, spring promotes the taper ringfeder and moves to right along axis direction, the elastic recovery of taper ringfeder self, taper ringfeder radial dimension shrinks, and loosens the cylinder jacket of processed mistake.
The beneficial effects of the utility model are: simple in structure, easy to operate, utilize the inner conical surface of taper ringfeder and the male cone (strobilus masculinus) of taper mandrel to cooperate, the taper ringfeder can axially move along the axis of taper mandrel, alleviate employee's labour intensity, guarantee the converted products quality, enhance productivity, be applicable to mass production.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Among the figure: 1 taper mandrel, 2 pull bars, 3 taper ringfeders, 4 springs, 5 nuts.
The specific embodiment
As shown in Figure 1, these anchor clamps comprise taper mandrel 1, pull bar 2, taper ringfeder 3, spring 4 and nut 5, the cylindrical of taper ringfeder 3 is axially opened shrinkage joint along even circumferential, taper ringfeder 3 is sleeved on the outer wall of taper mandrel 1 along axis direction through spring 4, pull bar 2 passes taper mandrel 1, the centre bore of spring 4 and taper ringfeder 3, one end hold-down nut 5 of pull bar 2, taper ringfeder 3 is done radially harmomegathus under the effect of the conical surface that cooperatively interacts, taper ringfeder 3 spreading radially when taper ringfeder 3 cooperates the conical surface to be moved to the left along the axis direction of taper mandrel 1, taper ringfeder 3 radial contraction when taper ringfeder 3 cooperates the conical surface to move right along the axis direction of taper mandrel 1.
In use, cylinder jacket to be processed is positioned on the taper ringfeder 3, pull bar 2 moves to left under external force, the nut 5 drive taper ringfeders 3 that screw with pull bar 2 move to left, taper ringfeder 3 spreading radially on the conical surface that cooperatively interacts, thereby the tensioner cylinder jacket so just forms the cylinder cover inner hole positioning states, and expanding force is as clamping power simultaneously; When the cylinder jacket completion of processing, pull bar 2 moves to right under external force, compressed spring 4 elastic recovery after pressure is disengaged, spring 4 promotes taper ringfeder 3 and moves to right along axis direction, the elastic recovery of taper ringfeder 3 self, taper ringfeder 3 radial dimensions shrink, and loosen the cylinder jacket of processed mistake.
