Abstract
The utility model provides a turning fixture for a valve sleeve of a steering gear. The turning fixture comprises a fixture main shaft which is formed by integrating a connecting shaft neck with a positioning shaft neck; and a rotating preventing positioning block is arranged on the outer circumference of the positioning shaft neck. The turning fixture for the valve sleeve of the steering gear is characterized in that a taper tensioning sleeve extends outwards from the positioning shaft neck; a tapered compressing sleeve is assembled in a tapered hole at the tapered tensioning sleeve; a bolt passes through the tapered compressing sleeve and then is screwed on the positioning shaft neck; the connecting shaft neck of the fixture main shaft is in match with an inner hole in a tool; and an inner threaded hole is formed in the end surface of the connecting shaft neck. According to the turning fixture for the valve sleeve of the steering gear, the fixture main shaft is in match grinding with the tapered hole in the main shaft of the tool through a morse tapered shank, so that the fit clearance between the fixture and the tool can be removed; after a part is clamped, and the bolt is crewed, a piston block is driven to uniformly expand an opening on a boss, so that the purpose of tensioning part is realized, and the fit clearance between the part and a clamping shaft can be removed; and if the bolt is released, the plug block is driven to be backed out of the tapered hole through the bolt, so that the convenience is provided for assembling and disassembling the part.
Description
Technical field
The utility model relates to a kind of machine tool, especially a kind of steering box valve pocket turning clamp.
Background technology
Steering box has another name called Zhuan Xiang Qi ﹑ steering wheel, and it is most important parts in the automobile steering system, and its effect is the direction of transfer that the augment direction dish passes to power and the change power of steering gear.The steering box valve pocket is one of core component of power steer assembly, and the height of the machining accuracy of its valve pocket itself directly affects the serviceability of power steer assembly.
At present, the anchor clamps of turning steering box valve pocket, comprise the anchor clamps main shaft, the anchor clamps main shaft is integrally formed by connecting axle journal and locating journal, the locating journal excircle is provided with the anti-rotation locating piece, and locating journal extends outward boss, and in axial sliding bolt is housed in the boss, cover has the pressure strip of compressing component on the bolt, as shown in Figure 1.There is following defective in described technical scheme: pass through Internal hole positioning behind the turning steering box valve pocket clamping 1., because the machining tolerance of endoporus is 5 silks, so turning steering box valve pocket cooperates the problem that has radial clearance with the clamping axle behind clamping, cause the dimension overproof after the processing and cause part to be scrapped; 2. chuck and machine tool chief axis cooperation itself just have beating of 2 silks, and all can there be certain fit clearance in cooperation between chuck and the anchor clamps, so, more may cause the increase of beating between turning steering box valve pocket and the clamping axle, thereby reduce machining accuracy.
Summary of the invention
The purpose of this utility model has provided a kind of steering box valve pocket turning clamp, and solve turning steering box valve pocket and behind clamping, cooperated the problem that has radial clearance with the clamping axle, and the problem that has the gap after having solved chuck and anchor clamps being connected.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of steering box valve pocket turning clamp, comprise the anchor clamps main shaft, the anchor clamps main shaft is integrally formed by connecting axle journal and locating journal, the locating journal excircle is provided with the anti-rotation locating piece, it is characterized in that: locating journal extends outward the tapered expanding cover, is fitted with the taper clamping sleeve in the taper hole of tapered expanding cover, and bolt passes the taper clamping sleeve and is tightened on the locating journal; The connection axle journal of anchor clamps main shaft cooperates with the endoporus of lathe, and the end face that connects axle journal is provided with internal thread hole.
Beneficial effect: anchor clamps main shaft of the present utility model adopts gapless to cooperate by Morse taper shank and tapered bore of machine tool spindle match grinding, is fixed with lathe by the left end tension with a pull bar again, has eliminated the fit clearance of anchor clamps and lathe, has improved the stability of anchor clamps; Behind the parts fixation, when bolt screws, drive the opening on the even spreading boss of chock, reach the purpose of tensioner part, eliminated the fit clearance between part and the clamping axle, when bolt unclamps, chock withdraws from taper hole under the drive of bolt, has made things convenient for the part loading and unloading.The utility model, simple in structure, cost of manufacture is low, has stopped the waste product that machining produces.
