When the machine tool is used for processing long workpieces, a certain workpiece needs to be positioned for processing, the three-jaw chuck needs to be detached at every time by the conical positioning piece of the machine tool, so that the three-jaw chuck can be adjusted, the weight of the three-jaw chuck is large, the detachment is time-consuming and labor-consuming, the labor cost is improved, and the working efficiency is reduced.
Specifically, the chuck 600 is mounted on the output end of the machine tool, when in use, the positioning device 500 is firstly taken down from the chuck 600, the coarse adjustment screw 200 is screwed to adjust the length of the elongated workpiece which can extend into the positioning sleeve 100, one end of the coarse adjustment screw 200 axially moves in the positioning sleeve 100, after the coarse adjustment screw 200 is adjusted to a roughly proper position, the locking mechanism 300 is adjusted, the coarse adjustment screw 200 is locked through the locking mechanism 300, the coarse adjustment screw 200 can not be screwed any more, and then the fine adjustment mechanism 400 is adjusted, so that the elongated workpiece can be positioned more accurately. After adjusting the rough adjusting screw 200 and the fine adjusting mechanism 400, the rough adjusting screw 200 together with the positioning sleeve 100 is extended into the through hole 611 until the stop 110 contacts and matches with the surface of the disk seat 610, the position of the clamping jaw 620 corresponds to the position of the slot 120, when the clamping jaw 620 clamps the workpiece, the clamping jaw 620 will pass through the slot 120 and not contact with the positioning sleeve 100. After the positioning device 500 is mounted on the chuck 600, the long workpiece can be inserted into the positioning sleeve 100, one end of the long workpiece is in contact with the fine adjustment mechanism 400, and the clamping jaw 620 slides inwards to clamp the long workpiece, so that the long workpiece can be positioned, and the long workpiece can be machined.
The utility model has the advantages that simple to operate need not dismantle three-jaw chuck, and fixes a position accurately, has improved the precision of work piece processing.
Example two:
the difference between the second embodiment and the first embodiment is that the stopper 110 has a fan shape.
Specifically, the stopper 110 is a portion in contact with the surface of the chuck 600, and is a portion where the positioning device 500 is matched with the chuck 600, when a long workpiece is processed, the chuck 600 can rotate, and the chuck 600 can drive the positioning device 500 to move together, the stopper 110 can keep taking the center of the positioning sleeve 100 as an axis when rotating, compared with other geometric shapes, the fan-shaped stopper 110 is more stable when rotating, and the fan-shaped stopper 110 cannot shake to cause failure in positioning the long workpiece.
Example three:
the third embodiment is different from the first embodiment in that the locking mechanism 300 includes a locking bolt 310 and a locking plate 320, the locking bolt 310 is rotatably connected with the locking plate 320, a groove 141 is formed in the first adjusting hole 140 and is engaged with the locking plate 320, and a thread engaged with the rough adjusting screw 200 is formed on the locking plate 320.
Generally, a locking mechanism adopts a bolt alone to lock the coarse adjustment screw rod, which may cause the thread on the coarse adjustment screw rod to be damaged, may cause the situation of thread slipping and the like, and may cause the failure of the device.
Specifically, the locking mechanism 300 adopts the locking piece 320 to cooperate with the coarse adjustment screw 200, when the coarse adjustment screw 200 is locked, the locking bolt 310 is screwed inwards, the locking bolt 310 pushes the locking piece 320, the locking piece 320 extrudes the coarse adjustment screw 200, the friction force between the locking piece 320 and the coarse adjustment screw 200 is increased during extrusion, the coarse adjustment screw 200 cannot be screwed any more, the locking purpose is achieved, the locking piece 320 is provided with a thread cooperating with the coarse adjustment screw 200, the thread on the locking piece 320 cannot be damaged when the locking piece 320 extrudes the coarse adjustment screw 200, and the occurrence of the situations such as thread slipping is avoided.
Example four:
the difference between the fourth embodiment and the first embodiment is that the fine adjustment mechanism 400 includes a fine adjustment bolt 410 and a fixed nut 420, the coarse adjustment screw 200 has a second adjustment hole 210 at the middle of one end of the positioning sleeve 100 and is engaged with the fine adjustment bolt 410, and the fixed nut 420 is sleeved on the fine adjustment bolt 410.
Specifically, when fine adjustment is performed, the fixing nut 420 is firstly unscrewed upwards, so that the fine adjustment bolt 410 can be screwed in the second adjustment hole 210; when the fine adjustment bolt 410 is screwed to a set length, the fixed nut 420 is screwed downwards, and the fixed nut 420 is in contact with the end face of the coarse adjustment screw rod 200, so that the fine adjustment bolt 410 cannot be screwed any more, the purpose of fixed length after fine adjustment is achieved, and the accuracy of the adjusted length is ensured.
Example five:
the difference between the fifth embodiment and the fourth embodiment is that an adjusting block 411 is disposed at one end of the fine adjusting bolt 410 outside the second adjusting hole 210.
Specifically, the setting of the adjusting block 411 enables sufficient stress points to exist when the fine adjustment bolt 410 is screwed, so that the fine adjustment bolt 410 can be accurately adjusted, the axial moving length of the fine adjustment bolt 410 during screwing can be judged through the rotating angle of the adjusting block 411, and the adjusting accuracy is improved.
The preferred embodiments of the present invention are described herein, but the scope of the present invention is not limited thereto. Modifications or additions to or replacement by similar means to those skilled in the art to which the invention pertains to the specific embodiments described herein are intended to be covered by the scope of the invention.
