Abstract
The utility model discloses an internal thread special gripper of a grinding ball screw rod nut, which is provided with an adjusting nut, a tightening sleeve and a hollow tightening central spindle, wherein the tightening central spindle is provided with a positive gear external thread; the tightening sleeve is provided with a negative gear external thread; the adjusting nut is provided with an internal thread, wherein the left half part is the positive gear thread and the right half part is the negative gear thread, so that the adjusting nut is rotated to drive the tightening sleeve and the tightening central spindle to move relative to each other. The utility model has the advantages that when the gripper is manufactured, the coaxial degree of the inner chamber of the tightening central spindle is ensured; simultaneously, when the gripper is installed on the machine tool, the spindle centre yarn of the gripper is ensured to be vertical to the end surface of the head of the machine tool; the gripper can be used conveniently; and people only need to put a nut adobe in the gripper and then rotate the adjusting nut to tighten, thus not only ensuring that the center of the working piece and the center of the head of the machine tool are concentric, but also ensuring that the central line of the work piece is vertical to the end surface of the machine head, thus not needing a dial indicator to revise repeatedly, saving the working hours and improving the manufacturing precision of the nut.
Description
Technical field
The utility model relates to a kind of anchor clamps, specifically, relates to a kind of anchor clamps that are used for grinding internal thread of ball screw nut, belongs to field of machining.
Background technology
In existing rolling function parts ball-screw manufacture process, the processing of internal thread of ball screw nut is carried out on the nut grinding machine, at first be earlier by the grinding machine workman with clamping workpiece to lathe with the scroll chuck clamping, and then use the measurer calibration of workpieces, should make workpiece centre and lathe headstock centres, make work centre line vertical again, the nut that grinds is met the requirements with the headstock end face.But correction work not only wastes time and energy but also is difficult to reach requirement, and each grinding machine workman technical merit also there are differences, and the nut that very difficult assurance processes is consistent, makes the precision of nut can not get guaranteeing.
The utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, and a kind of special clamp for grinding internal thread of ball screw nut is provided, and both can save the working time, can guarantee the nut machining accuracy again.
Special clamp for grinding internal thread of ball screw nut of the present utility model, be provided with the tensioner mandrel of adjusting nut, tensioner cover and hollow, wherein, the tensioner mandrel is provided with positive tooth external screw thread, tensioner puts and is provided with anti-tooth external screw thread, and adjusting nut has internal thread, and its left one side of something is positive pitch thread, right one side of something is anti-pitch thread, makes can drive when rotating adjusting nut between tensioner cover and the tensioner mandrel to relatively move.
Preferably, between said tensioner cover and the tensioner mandrel taper seat that combines is arranged, be convenient to accurate location.
More preferably, the conical surface of said tensioner mandrel is provided with 5 equally distributed open slots, as claw, can be used for clamping and unclamping workpiece.
The utlity model has following technique effect, when making anchor clamps, guaranteed the axiality of tensioner mandrel inner chamber, simultaneously on lathe, guarantee that again the clamp shaft heart yearn is vertical with lathe headstock end face during sectional fixture, so anchor clamps of the present utility model are easy to use, only need put the nut base into anchor clamps, rotate the adjusting nut tensioner, can guarantee workpiece centre and lathe headstock centres, can guarantee that again work centre line is vertical with the headstock end face, do not need to proofread and correct repeatedly with amesdial again, not only saved man-hour but also improved the machining accuracy of nut.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of special clamp for grinding internal thread of ball screw nut of the present utility model.
Wherein 1 is adjusting nut, and 2 is the tensioner mandrel, and 3 is the tensioner cover, and 4 is nut to be ground.
The specific embodiment
As shown in Figure 1, special clamp for grinding internal thread of ball screw nut of the present utility model, be provided with adjusting nut 1, the tensioner mandrel 2 of tensioner cover 3 and hollow, wherein, tensioner mandrel 2 is provided with positive tooth external screw thread, tensioner cover 2 is provided with anti-tooth external screw thread, adjusting nut 1 has internal thread, its left one side of something is positive pitch thread, right one side of something is anti-pitch thread, makes can drive when rotating adjusting nut 1 between tensioner cover 3 and the tensioner mandrel 2 to relatively move. between tensioner cover 3 and the tensioner mandrel 2 taper seat that combines is arranged, be convenient to accurate location. and the conical surface of tensioner mandrel 2 is provided with 5 equally distributed open slots, as claw, can be used for clamping and unclamping workpiece.
Special clamp for grinding internal thread of ball screw nut of the present utility model is performed such work: nut 4 to be ground is put into tensioner mandrel 2 inner chambers, positive modulation joint nut 1, clamp nut 4 to be ground, can carry out grinding this moment, grinding finishes, counter-rotating adjusting nut 1 then unclamps workpiece nut 4, can take off the good nut of grinding 4.Because the axiality of tensioner mandrel 2 inner chambers is higher, between tensioner mandrel 2 and the tensioner cover 3 the circular cone faying face is arranged in addition, therefore accurate positioning can proofread and correct, and can guarantee the accuracy of each nut.
Claims (3)
1. special clamp for grinding internal thread of ball screw nut, it is characterized in that, said anchor clamps are provided with the tensioner mandrel of adjusting nut, tensioner cover and hollow, wherein, the tensioner mandrel is provided with positive tooth external screw thread, and tensioner puts and is provided with anti-tooth external screw thread, adjusting nut has internal thread, its left one side of something is positive pitch thread, and right one side of something is anti-pitch thread, makes can drive when rotating adjusting nut between tensioner cover and the tensioner mandrel to relatively move.
2. special clamp for grinding internal thread of ball screw nut according to claim 1 is characterized in that, between said tensioner cover and the tensioner mandrel taper seat that combines is arranged, and is convenient to accurate location.
