Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below. The structures, proportions, sizes, etc. shown in the drawings are shown only in connection with the present disclosure, and are not intended to limit the scope of the utility model, since any modification, variation in proportions, or adjustment of the size, etc. of the structures, proportions, etc. should be considered as falling within the spirit and scope of the utility model, without affecting the effect or achievement of the objective. Also, the terms "upper", "lower", "left", "right", "middle", and the like are used herein for descriptive purposes only and are not intended to limit the scope of the utility model for modification or adjustment of the relative relationships thereof, as they are also considered within the scope of the utility model without substantial modification to the technical context.
Referring to fig. 1 to 3, a fixture for a high-precision turning tool includes a base 1 and a connecting nut 2 located inside the base 1, where the connecting nut 2 and the base 1 are disposed in a gap. The base 1 is connected with a main shaft of the numerical control lathe and is locked on the main shaft of the numerical control lathe through an inner hexagon screw. The connecting nut 2 is connected with an oil cylinder of the numerical control lathe.
The front end of the connecting nut 2 is connected with a pull rod 3. The pull rod 3 passes through the base 1 and is slidable within the base 1. The front end of the pull rod 3 is provided with a pressure head 31 positioned outside the base 1. The ram 31 is of T-shaped configuration. The pull rod 3 is connected with the connecting nut 2 through threads, so that the connecting structure is simple and the installation is convenient.
The front end of the base 1 is provided with a spring sleeve 4. The grooves are staggered on the periphery of the spring sleeve 4 at opposite intervals. And the length of the groove body is smaller than that of the spring sleeve 4, and the groove body can enable the circumferential direction of the spring sleeve to expand and deform outwards comprehensively. The front end of the base 1 is provided with a slope step structure 11 with a diameter reduced along the axial direction, and the spring sleeve 4 is sleeved on the slope step structure 11. The pressing head 31 contacts the right end face of the spring housing 4 to press the spring housing 4. The pressing head 31 with the T-shaped structure can comprehensively squeeze the spring sleeve 4, so that the spring sleeve 4 is guaranteed to deform under the whole stress. The slope step structure 11 positions the inner hole of the spring sleeve 4, prevents the right end of the spring sleeve 4 from being stressed to push the spring sleeve 4 leftwards, and ensures that the position of the spring sleeve 4 is still fixed after the spring sleeve 4 is extruded.
The outer side of the spring sleeve 4 is connected with an inner hole of the workpiece 5. The right end part of the spring sleeve 4 protrudes from the end surface of the base 1. The front end of the base 1 is also provided with a cushion block which is positioned at the rear end of the spring housing 4 and is contacted with the workpiece to position the workpiece 5. The workpiece 5 is an outer sun gear clutch hub assembly having a bushing 51 in its inner bore, and the spring sleeve 4 contacts the inner bore of the bushing 51 to secure the workpiece 5. When the workpiece 5 is installed, the left end face of the workpiece 5 is in contact with the cushion block 6, and the workpiece 5 is limited. Meanwhile, the bushing 51 is just sleeved on the spring sleeve 4, and the length of the spring sleeve 4 is longer than that of the bushing 51, so that the spring sleeve 4 can fully compress the bushing 51.
During assembly, the pull rod 3 penetrates into the base 1 from the front end, then the connecting nut 2 is put into the base 1 from the rear and connected with the pull rod 3, and then the cushion block is assembled in place. When the numerical control lathe is needed to be used, the connecting nut 2 is connected with the oil cylinder, the base 1 is arranged on the main shaft of the numerical control lathe, and finally the workpiece 5 is assembled in place.
When the workpiece 5 needs to be processed, the oil cylinder of the numerical control lathe is started, and the oil cylinder pulls the connecting nut 2 to drive the pull rod 3 to move leftwards. At this time, the pull rod 3 presses the end face of the spring housing 4, after the spring housing 4 is pressed, the spring housing 4 is elastically deformed, and the spring housing 4 expands outwards, so that the inner hole of the workpiece 5 is expanded through the spring housing 4. The processing is completed, the oil cylinder is reset, the pull rod 3 and the connecting nut 2 are reset, the spring sleeve 4 loosens the workpiece 5, and the workpiece 5 can be removed from the spring sleeve 4.
Compared with the prior art, the clamp of the high-precision turning tool disclosed by the utility model has the advantages that the workpiece is clamped by the spring sleeve, the contact area is increased, the clamping rigidity is good, and the stability of the workpiece during machining is ensured.
The utility model and its embodiments have been described above by way of illustration and not limitation, and the utility model is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present utility model.
