Description
Technical Field
The application relates to the technical field of machine tools, in particular to a multipurpose lathe chuck.
Background
Self-centering chucks and single action chucks are common fixtures for lathes that are widely used in production. The self-centering chuck is suitable for clamping round parts, the jaws are linked through a certain mechanical structure, the workpieces are automatically centered after being clamped, the workpieces are convenient and rapid to clamp, but the workpieces with irregular shapes cannot be clamped, and the precision is reduced after the self-centering chuck is used for a long time. The clamping jaws of the single-action chuck move independently, cannot be automatically centered after clamping a workpiece, and must be manually aligned, so that the workpiece with an irregular shape can be clamped except for a circular part.
In actual production process, because part kind is various, the shape is complicated, often need switch back and forth between two kinds of chucks, waste time and energy, aggravate the wearing and tearing of lathe and anchor clamps easily moreover, cause instrument life to shorten, influence the precision of the part of processing simultaneously, can't reach the requirement of high efficiency, accurate processing part.
SUMMERY OF THE UTILITY MODEL
The application provides a multi-purpose lathe chuck to solve the problem that single chuck can't carry out the clamping to complicated shape part under the condition of not changing the chuck.
A multi-purpose lathe chuck comprising: the device comprises a central gear, a satellite gear set, a lead screw nut pair and a clamping jaw;
the satellite gear sets are meshed with the central gear, the lead screw nut pair is meshed with the satellite gear set (2), and the clamping jaws are arranged on the lead screw nut pair for searching foxes;
wherein, screw nut pair includes: a lead screw and a cylindrical rack;
the lead screw is rotatably connected with the cylindrical rack.
Preferably, the satellite gear set comprises: a first gear and a second gear;
the first gear is meshed with the central gear, and the second gear is meshed with the cylindrical rack.
Preferably, the first gear is rigidly connected to the second gear.
Preferably, the jaws are arranged on the lead screw and away from the cylindrical rack.
Known by above technical scheme, this application provides a multi-purpose lathe chuck, includes: the central gear, the satellite gear group, screw nut is vice, the jack catch, can fix a position the part that needs processing through from centering chuck, can also utilize single acting chuck to carry out the centre gripping to the part that the shape is complicated simultaneously, this kind of design both can satisfy the part that the shape is fixed and carry out the clamping, also can satisfy the clamping that has complicated shape part, just so need not carry out the change of chuck to different parts in the actual work, work efficiency has been improved to a certain extent, the wearing and tearing of lathe and anchor clamps have also been reduced simultaneously, the life of equipment has been prolonged.

Detailed Description
Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following examples do not represent all embodiments consistent with the present application. But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.
In the technical scheme provided in this application, provide a multi-purpose type lathe chuck, please refer to fig. 1, include: the device comprises a central gear 1, a satellite gear set 2, a screw nut pair 3 and a clamping jaw 4;
the satellite gear sets 2 are meshed with the central gear 1, the lead screw nut pair 3 is meshed with the satellite gear sets 2, and the clamping jaws 4 are arranged on the lead screw nut pair 3;
wherein, the screw nut pair 3 comprises: a lead screw 31 and a cylindrical rack 32;
the lead screw 31 is rotatably connected to the cylindrical rack 32.
Further, the satellite gear set 2 includes: a first gear 21 and a second gear 22;
the first gear 21 is meshed with the central gear 1, and the second gear 22 is meshed with the cylindrical rack (32).
Further, the first gear 21 is rigidly connected to the second gear 22.
Further, the jaw 4 is disposed on the lead screw 31 and away from the cylindrical rack 32.
The application provides a multi-purpose lathe chuck's theory of operation as follows:
the satellite gear set 2 is meshed with the cylindrical rack 32 to drive the rack and the clamping jaws 4 fixed on the rack to do reciprocating linear motion, please refer to fig. 2, at the moment, the cylindrical rack 4 and the lead screws 31 fixed on the rack do not rotate around the axes of the cylindrical rack and the lead screws 31 and nuts do not have displacement, the lead screws 31 and the nuts can be regarded as a rigidly connected whole, clamping and loosening of the clamping jaws 4 are achieved, the moving range of the clamping jaws 4 is determined by the length of the cylindrical rack 32, and the satellite gears are meshed with the center wheel simultaneously and move synchronously, so that self-centering is achieved.
When the jaw 4 needs to move independently, the adjusting nut at one end of the cylindrical rack 32 can be rotated respectively, so that the cylindrical rack 32 rotates around the axis of the cylindrical rack, the screw rod 31 is driven to rotate, and the nut slider and the jaw 4 fixed on the nut slider are driven to do reciprocating linear motion along the axis. The four cylindrical racks 32 can independently rotate around respective axes, and do not drive other screw nut pairs 3 to move when rotating, so that the movement of the clamping jaws 4 is independent and does not influence each other when adjusting the adjusting nuts at one ends of the cylindrical racks 32 independently. The range of independent movement of the jaws 4 is determined by the length of the lead screw.
Therefore, when the dual purposes of self-centering and single-acting are realized, the single-acting structure can also carry out fine adjustment compensation on eccentric wear of a self-centering part along with use, so that the machine tool is more convenient to maintain.
To sum up, the application provides a multi-purpose type lathe chuck includes: the central gear, the satellite gear group, screw nut is vice, the jack catch, can fix a position the part that needs processing through from centering chuck, can also utilize single acting chuck to carry out the centre gripping to the part that the shape is complicated simultaneously, this kind of design both can satisfy the part that the shape is fixed and carry out the clamping, also can satisfy the clamping that has complicated shape part, just so need not carry out the change of chuck to different parts in the actual work, work efficiency has been improved to a certain extent, the wearing and tearing of lathe and anchor clamps have also been reduced simultaneously, the service life of equipment has been prolonged.
The embodiments provided in the present application are only a few examples of the general concept of the present application, and do not limit the scope of the present application. Any other embodiments that can be extended by the solution according to the present application without inventive efforts will be within the scope of protection of the present application for a person skilled in the art.
