Abstract
The utility model relates to a clamping jig for machining the outer diameter of the two ends of the same shaft at one time. The clamping jig is fixedly arranged on a numerically controlled lathe through a three-claw chuck, and is characterized in that the main body of the clamping jig is a clamping shaft; a clamping groove is vertically and downwards formed from the center part of the upper end surface of the clamping shaft; a horizontal clamping hole is formed in the middle position of the clamping groove; a horizontal elastic hole is formed in the bottom of the clamping groove; the round point of the clamping hole, the round point of the elastic hole and the central symmetrical surface of the clamping groove are on the same plane; and a bolt vertically penetrating through the clamping groove is arranged on the head part of the clamping shaft. The clamping jig is used for machining the required outer diameter of the two ends of a shaft workpiece; the coaxiality after machining is ensured; and the shaft workpiece penetrates through the clamping hole and is tightly screwed by the bolt, and the jig is clamped on the three-claw chuck of the numerically controlled lathe to turn the outer diameter of the two ends of the shaft workpiece, so that the coaxiality of the two end surfaces after machining is ensured.
Description
Technical field:
The utility model relates to a kind of clamping fixture, relates in particular to a kind ofly to carry out clamping for the scroll chuck on the numerically controlled lathe, can disposablely finish the external diameter processing of same axle two ends, guarantees the clamping fixture of its two ends axiality.
Background technology:
In numerically controlled lathe, be used for when needing the axle of two ends external diameters processing, such as: bolt, latch etc. are part similarly, an end of workpiece need to be extend in the scroll chuck, utilizes the rotation of rotating disk, the other end is carried out the car external diameter process; Then turn workpiece, the end after the processing extend in the scroll chuck again, before an end is carried out the car external diameter again process.Such operation processing method is easy to cause axial line behind the turning of workpiece two ends not on the same straight line, namely can not guarantee the axiality after its processing.
Summary of the invention:
The technical problem that the utility model solves guarantees the axiality of the rear both ends of the surface of its processing, and is easy to manually-operated clamping fixture after providing the external diameter processing of a kind of same axle two ends.
The technical scheme in the invention for solving the technical problem is: a kind of clamping fixture for the same axle of disposable processing two ends external diameter, in the scroll chuck that is used in numerically controlled lathe that this clamping fixture is fixed, this clamping fixture main body is clamp axis, offer vertically downward a holding tank from the centre of clamp axis upper surface, be provided with horizontal clamping hole in the centre position of described holding tank, offer a horizontal springhole at the bottom position of described holding tank, the round dot of described clamping hole, the Central Symmetry face of the round dot of springhole and holding tank in one plane, the head of this clamp axis is provided with a bolt that vertically passes holding tank.
Further, make things convenient for this clamping fixture to pack in the scroll chuck, can carry out the school cutter to this clamping fixture, on described clamp axis, from the periphery at the place, upper surface of clamp axis, cut vertically downward a vertical alignment surface, this alignment surface is vertical with the plane of symmetry of holding tank.
Further, holding tank is separated into two grip blocks with clamp axis, in order to guarantee two grip blocks under the effect of bolt, and can be flexible to drawing close together, reach the effect of fastening workpiece, the number of degrees of the corresponding central angle of circular arc of described springhole are 160 °～180 °.
The beneficial effect of this device: this clamping fixture is used for an axle is needed two ends external diameter processing, guarantee its processing after axiality, this axle is passed clamping hole, screwed by bolt afterwards, then this tool is clamped on the scroll chuck of numerically controlled lathe, this axle is carried out two ends car external diameter processing, guaranteed the axiality of the rear both ends of the surface of its processing, and this clamping fixture is easy to manually-operated, has improved to a great extent clamping efficient.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of the utility model when the specific embodiment.
Among the figure: 1, clamp axis 2, bolt 3, holding tank 4, alignment surface 5, clamping hole 6, springhole 7, shaft-like work.
The specific embodiment:
A kind of clamping fixture for the same axle of disposable processing two ends external diameter as shown in Figure 1, in the scroll chuck that is used in numerically controlled lathe that this clamping fixture is fixed, this clamping fixture main body is clamp axis 1, offer vertically downward a holding tank 3 from the centre of clamp axis 1 upper surface, be provided with horizontal clamping hole 5 in the centre position of described holding tank 3, the pore size of this clamping hole 5 equals the diameter in the centre position of shaft-like work 7 that need to be processed, offer a horizontal springhole 6 at the bottom position of described holding tank 3, the round dot of described clamping hole 5, the Central Symmetry face of the round dot of springhole 6 and holding tank 3 in one plane, the head of this clamp axis 1 is provided with a bolt 2 that vertically passes holding tank 3.
Further, pack in the scroll chuck for making things convenient for this clamping fixture, can carry out the school cutter to this clamping fixture, on described clamp axis 1, from the periphery at the place, upper surface of clamp axis 1, cut vertically downward a vertical alignment surface 4, this alignment surface 4 is vertical with the plane of symmetry of holding tank 3.
Further, holding tank 3 is separated into two grip blocks with clamp axis 1, in order to guarantee two grip blocks under the effect of bolt 2, and can be flexible to drawing close together, reach the effect of fastening workpiece, the number of degrees of the corresponding central angle of circular arc of described springhole 6 are 160 °～180 °.
As shown in Figure 2, this clamping fixture is used for a shaft-like work 7 is needed two ends external diameter processing, guarantee its processing after axiality, this shaft-like work 7 is passed clamping hole 5, screwed by bolt 2 afterwards, then this clamping fixture is clamped on the scroll chuck of numerically controlled lathe, when the cutter tool setting is processed, the head of cutter touches on the alignment surface 4, this shaft-like work 7 is carried out two ends car external diameter processing, guaranteed the axiality of both ends of the surface after its processing, and this clamping fixture is easy to manually-operated, improved to a great extent clamping efficient.
It is emphasized that, it more than is better implementation column of the present utility model, be not that the utility model is done any type of restriction in appearance, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
