Abstract
The utility model discloses a tire expanding fixture for use in machining of a motor shell. The tire expanding fixture comprises a taper mandrel, a fixing sleeve, an expansion sleeve, a spring, a pressure ring and a fastening nut, and is structurally characterized in that the fixing sleeve is fixed to the front part of the taper mandrel through a screw; the expansion sleeve is sleeved on the middle part of the taper mandrel with the front end being inserted into the fixing sleeve for positioning; the spring is arranged at a corresponding position between the back end inner surface of the expansion sleeve and the middle part of the taper mandrel; the pressure ring is sleeved at the back end of the taper mandrel and is pressed onto the back end outer surface of the expansion sleeve; the fastening nut is screwed into one end of the taper mandrel and is pressed against the pressure ring, and the expansion ring is pressed against the expansion sleeve. During use, the fastening nut is unscrewed after machining is finished, the expansion sleeve resets and releases pressure under the action of the spring, and machined workpieces are taken out. The tire expanding fixture has the characteristics of simple structure, convenience in maintenance, low manufacturing cost and the like.
Description
Technical field
The utility model belongs to clamping tool for machine work apparatus field, specifically a kind of frock clamp for motor case processing.
Background technology
Tradition casing processing is to utilize three to grab chuck and block the first car of front end and go out rear end and reverse end for end car again and go out front end and seam, also having first car to go out unshakable in one's determination shelves utilizes swollen tire swelling car to go out front and back end seam, like this take the shelves unshakable in one's determination of casing under seam one cutter of benchmark two ends, reach the form and position tolerance of processing.
Summary of the invention
The purpose of this utility model is to provide a kind of expander fixture of motor case processing, simple in structure, easy to maintenance, low cost of manufacture.
The purpose of this utility model is to realize like this, the expander fixture of described a kind of motor case processing, comprise tapering mandrel, fixed cover, set of books, spring, trim ring and clamp nut, its design feature is that described fixed cover is screwed on the front portion of tapering mandrel, middle part and its front end that set of books is enclosed within tapering mandrel are inserted into location in fixed cover, corresponding position between the rear end of set of books inner face and the middle part of tapering mandrel is provided with spring, trim ring is enclosed within on the rear end of tapering mandrel and pushes down on the outside, rear end of set of books, clamp nut screws in tapering mandrel one end and pushes down trim ring, trim ring compresses set of books.
The front end of tapering mandrel is for inserting the spindle hole of lathe.
Advantage of the present utility model is: the position between the rear end of set of books inner face and the middle part of tapering mandrel is provided with powerful spring, thereby there is certain distance to make set of books be in pressure release state under the effect of spring, between set of books and tapering mandrel, trim ring is enclosed within the rear end of tapering mandrel and pushes down the outside, rear end of set of books, clamp nut pins tapering mandrel one end and pushes down trim ring and makes it compress trim ring, thereby trim ring is pushed down set of books again and made set of books move inward swelling set of books and swelling workpiece (support unshakable in one's determination shelves); During use, release clamp nut after completion of processing, set of books resets and makes set of books pressure release under the effect of spring, takes out the workpiece machining.There is the features such as simple in structure, easy to maintenance, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is partial cutaway structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the expander fixture of a kind of motor case processing described in the utility model, comprise tapering mandrel 1, fixed cover 2, set of books 3, spring 4, trim ring 5 and clamp nut 6, its design feature is that the front end of tapering mandrel 1 is for inserting the spindle hole of lathe, fixed cover 2 is screwed on the front portion of tapering mandrel 1, fixed cover 2 entangles set of books 3 front ends, be used for fixing set of books 3, middle part and its front end that set of books 3 is enclosed within tapering mandrel are inserted into the interior location of fixed cover 2, position between the rear end of set of books 3 inner face and the middle part of tapering mandrel 1 is provided with powerful spring 4, under the effect of spring 4, thereby between set of books 3 and tapering mandrel 1, there is certain distance to make set of books 3 be in pressure release state, trim ring 5 is enclosed within the rear end of tapering mandrel 1 and pushes down the outside, rear end of set of books 3, clamp nut 6 pins tapering mandrel 1 one end and pushes down trim ring 5 and makes it compress trim ring, thereby pushing down set of books 3 again, trim ring 5 make set of books 3 move inward swelling set of books 3 and swelling workpiece (shelves unshakable in one's determination of support), during use, release clamp nut 6 after completion of processing, set of books 3 resets and makes set of books 3 pressure releases under the effect of spring 4, takes out the workpiece machining.
