Abstract
The invention discloses a tensioning fixing device, which comprises a clamp body, a tensioning sleeve, an inner sleeve, a fixing rod, a pin and an adjusting ring, wherein the tensioning sleeve is used for clamping the inner wall of a workpiece, the outer diameter of the upper part of the inner sleeve is large, the outer diameter of the lower part of the inner sleeve is small, the fixing rod is sheathed with the inner sleeve, the adjusting ring is used as a force applying device, the tensioning sleeve is fixedly arranged on the clamp body, the inner sleeve is arranged in the tensioning sleeve, one end of the pin is abutted against the inner sleeve, the other end of the pin is abutted against the lower surface of the adjusting ring, the adjusting ring is provided with a concave groove matched with a wrench head, and the adjusting ring is connected with the clamp body by threads. When the tensioning fixing device is used in operation, the threads are tightly screwed by a wrench compressing the concave groove of the adjusting ring, the adjusting ring jacks up the pin, the pin jacks up the inner sleeve, the inner sleeve moves downwards under the action force of the pin, the upper end of the inner sleeve enters the tensioning sleeve, and the tensioning sleeve is tensioned to jack up the inner wall of the workpiece. The tensioning fixing device has advantage that the accuracy of the workpiece is improved by the fine adjusting of clamping jaws through rotating the threads.
Description
Technical field
The invention belongs to the technical field of anchor clamps, relate in particular to a kind of tensioner fixture.
Background technology
In the machine-building process, anchor clamps commonly used fix processing object, make it to occupy correct position, to accept construction or to detect.In existing clamp assembly, workpiece is fixed in place by the coupling between himself physical form and the bare terminal end correspondingly-shaped.When practical operation, the clamping that the reciprocating motion by force application apparatus realizes workpiece with unclamp, often the radian of motion is larger, is difficult to realize the fine setting to jaw, makes the tolerance of workpiece be difficult to control.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of tensioner fixture, can finely tune jaw by the rotation screw thread.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of tensioner fixture, comprise chuck body, be used for the up big and down small inner sleeve of expansion sleeve, the external diameter of clamping work pieces inwall, the fixed bar with the inner sleeve socket, pin and as the adjustable ring of force application apparatus, expansion sleeve is fixed on the chuck body, in be set in the expansion sleeve, one end and the inner sleeve of pin offset, the lower surface of the other end and adjustable ring offsets, adjustable ring is provided with the groove with the driving end coupling, and adjustable ring is threaded with chuck body.
Compared with prior art, the invention has the advantages that: during operation, the groove that utilizes spanner to compress adjustable ring screws screw thread, adjustable ring holds out against pin, pin holds out against inner sleeve, in be enclosed within the active force of pin, move downward, the upper end of inner sleeve enters expansion sleeve, thus expansion sleeve tensioner top tight workpiece inwall.The present invention can finely tune jaw by the rotation screw thread, has increased the accuracy of workpiece.
Further, described fixed bar is provided with stage clip, and an end of stage clip is connected on the fixed bar, puts in the other end is connected to, and helps inner sleeve upwards to reset.
Further, the lower surface of described adjustable ring is provided with thrust bearing, and described pin and thrust bearing offset, and can reduce between adjustable ring lower surface and the pin and rub.
Further, described chuck body is provided with alignment pin, in order to offset with the workpiece outer wall.
Description of drawings
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
Fig. 1 is the structural representation of tensioner fixture embodiment of the present invention.
The specific embodiment
As shown in Figure 1, a kind of tensioner fixture of the present invention, comprise chuck body 1, be used for the up big and down small inner sleeve 3 of expansion sleeve 2, the external diameter of clamping work pieces 10 inwalls, the fixed bar 4 with inner sleeve 3 sockets, pin 11 and as the adjustable ring 5 of force application apparatus, expansion sleeve 2 is fixed on the chuck body 1, inner sleeve 3 is located in the expansion sleeve 2, one end and the inner sleeve 3 of pin 11 offset, the lower surface of the other end and adjustable ring 5 offsets, adjustable ring 5 is provided with the groove 6 with the driving end coupling, and adjustable ring 5 is threaded with chuck body 1.Described fixed bar 4 is provided with stage clip 7, and an end of stage clip 7 is connected on the fixed bar 4, and the other end is connected on the inner sleeve 3, helps inner sleeve 3 upwards to reset.The lower surface of described adjustable ring 5 is provided with thrust bearing 8, and described pin 11 offsets with thrust bearing 8, can reduce friction between adjustable ring 5 lower surfaces and the pin 11.Described chuck body 1 is provided with alignment pin 9, in order to offset with workpiece 10 outer walls.
When the present invention operated, the groove 6 that utilizes spanner to compress adjustable ring 5 screwed screw thread, and adjustable ring 5 holds out against pin 11, pin 11 holds out against inner sleeve 3, and inner sleeve 3 moves downward under the active force of pin 11, the upper end of inner sleeve 3 enters expansion sleeve 2, thus expansion sleeve 2 tensioner top tight workpieces 10 inwalls; Unscrew adjustable ring 5, adjustable ring 5 floatings, pin 11 also floats under the effect of stage clip 7, and inner sleeve 3 moves upward under the effect of pin 11 floatings, and expansion sleeve 2 is withdrawed from the upper end of inner sleeve 3, thus workpiece 10 inwalls are unclamped in expansion sleeve 2 retractions.
For a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
