Description
Technical Field
The utility model belongs to the technical field of machining anchor clamps, concretely relates to car anchor clamps of long thin wall pipe.
Background
With the trend of light weight development of mechanized products, parts are correspondingly developed towards the direction of light weight and thinness, wherein a thin-walled tube is a part which is difficult to machine in machining, particularly a long thin-walled tube, and generally needs to be clamped by a three-jaw chuck on a lathe spindle during machining. Therefore, a clamp is urgently needed to be developed to clamp the long thin-walled tube for turning, and the product percent of pass is improved.
Disclosure of Invention
In order to solve the above problems, the present invention provides a turning clamp for a long thin-wall pipe.
The utility model provides a turning clamp of long thin-walled tube, includes the dabber, the dabber includes dabber polished rod, threaded rod, the cover is equipped with taper sleeve one, spring housing one, taper sleeve two, spring housing two in proper order on the dabber polished rod, be equipped with the nut on the threaded rod, the spindle is equipped with the location ring of location taper sleeve one, the tip diameter of taper sleeve one, taper sleeve two with the internal diameter of spring housing one, spring housing two is the same.
In order to facilitate processing, a tool withdrawal groove is arranged between the mandrel polish rod and the threaded rod.
In order to clamp a workpiece conveniently, a plurality of elastic openings are uniformly distributed on the first spring sleeve and the second spring sleeve.
Furthermore, the number of the elastic openings on the first spring sleeve and the second spring sleeve is 8.
In order to facilitate clamping on a lathe, the center of the end face of one end of the mandrel is provided with a center hole.
In order to position the workpiece conveniently, a positioning step is arranged on the first spring sleeve.
The utility model discloses turning clamp of long thin wall pipe, compared with the prior art, its beneficial effect lies in: the utility model discloses the clamping is convenient, because the three-jaw chuck of lathe is not direct action on the work piece, so can not make the work piece produce and warp, the form and position error of the work piece of processing out is little, and size precision is high, and the rejection rate is low.

Detailed Description
The principles and features of the present invention are described below in conjunction with the following examples, which are set forth only for the purposes of explanation and are not intended to limit the scope of the present invention.
As shown in fig. 1, a turning clamp for a long thin-walled tube comprises a mandrel 1, wherein the mandrel 1 comprises a mandrel polished rod and a threaded rod, a first taper sleeve 3, a first spring sleeve 5, a second taper sleeve 8 and a second spring sleeve 9 are sequentially sleeved on the mandrel polished rod, a nut 11 is arranged on the threaded rod, a positioning ring 2 for positioning the first taper sleeve 3 is arranged on the mandrel 1, and the diameters of the small ends of the first taper sleeve 3 and the second taper sleeve 8 are the same as the inner diameters of the first spring sleeve 5 and the second spring sleeve 9.
For convenience of processing, a tool withdrawal groove 10 is arranged between the mandrel polish rod and the threaded rod.
In order to clamp a workpiece conveniently, a plurality of elastic openings 6 are uniformly distributed on the spring sleeve I5 and the spring sleeve II 9.
Furthermore, the number of the elastic openings 6 on the first spring sleeve 5 and the second spring sleeve 9 is 8.
In order to facilitate clamping on a lathe, the center of the end face of one end of the mandrel 1 is provided with a tip hole 12.
In order to position the workpiece conveniently, the first spring sleeve 5 is provided with a positioning step 4.
The utility model discloses a realize through following mode: when the machining device is used, the first taper sleeve 3, the first spring sleeve 5, the second taper sleeve 8 and the second spring sleeve 9 are sequentially sleeved on a mandrel polish rod, the nut 11 is installed and pre-locked, then a workpiece 7 to be machined is installed on the surface formed by the first spring sleeve 5 and the second spring sleeve 9, then the nut 11 is continuously rotated, so that the first taper sleeve 3 pushes the second spring sleeve 9, the second spring sleeve 9 pushes the second taper sleeve 8, the second taper sleeve 8 pushes the first spring sleeve 5, the first spring sleeve 5 and the second spring sleeve 9 are outwards tensioned under the action of the elastic openings 6 of the first spring sleeve 5 and the second spring sleeve 9, the workpiece 7 is clamped, the mandrel 1 is clamped on a lathe, a tip is jacked, and the mandrel 1 is aligned to jump, so that the workpiece can be machined.
The utility model discloses the clamping is convenient, because the three-jaw chuck of lathe is not direct action on the work piece, so can not make the work piece produce and warp, the form and position error of the work piece of processing out is little, and size precision is high, and the rejection rate is low.
The protection scope of the present invention is not limited to the technical solution disclosed in the specific embodiment, and all the modifications, equivalent replacements, improvements, etc. made by the technical entity of the present invention to the above embodiments all fall into the protection scope of the present invention.
