Abstract
The utility model relates to a central positioner, which is a special tool for repairing motor vehicles. The utility model is mainly composed of a centering risen finger, a slide conical sleeve, a positioning cylinder and a positioning rod, wherein, the center of the centering risen finger is provided with a step ladder through hole, the head of the step ladder through hole is small, and the tail of the step ladder through hole is big; the head is provided with a plurality of through grooves which are uniformly distributed, and a metal petal shape is formed; the diameter of the head of the centering risen finger depends on the diameter of a bearing bore of the model of the motor vehicles which are positioned. The head of the positioning rod is provided with a conical positioning point, and the outer diameter of the head is matched with the inner diameter of the through hole of the centering risen finger; the inner part of the slide conical sleeve is provided with a conical sleeve of the through hole which is matched with the outer diameter of the positioning cylinder. The central positioner can be matched with the centering risen finger with the corresponding outer diameter according to the requirements of the bore diameter of the front bearing of a first shaft of a speed changer of the motor vehicles with different models, so the utility model is suitable for various motor vehicles. The utility model has the advantages of scientific and reasonable schemes, simple structure, and reliable positioning.
Description
One, technical field:
The utility model relates to the special tool that a kind of self-propelled vehicle is repaired.Specifically: be a kind of special tool that clutch plate center and bearing center are located when being used for automobile clutch and repairing.
Two, background technology:
In self-propelled vehicle maintenance practice, the maintainer is sorely distressed for the clutch plate center and the bearing center orientation problem of power-transfer clutch, because accurately the location will rely on the primary shaft of engine speed changer, because the special assembling relation, it is very difficult to take out primary shaft from engine speed changer; Simultaneously because the variation of motor vehicle model, when changing a certain vehicle clutch driven disc, must use former car primary shaft.So it also is impossible adopting the method for the instrument primary shaft of a certain vehicle to solve all vehicle clutch plate centralized positioning problems.
Three, summary of the invention:
The purpose of this utility model provides a kind of centralized positioning device, is used for solving this difficult problem of automobile clutch maintenance.
For solving above-mentioned task, the solution that the utility model adopted is: the centralized positioning device mainly is made up of rise finger, slip conical bush, positioning tube, radius stay of centering, the centering finger center of rising has a big ladder hole of little tail, head has a plurality of well-distributed grooves, form the metal flap, afterbody has external screw thread, matches with the head negative thread of positioning tube, embossing is put into effect at the middle part, and the head diameter that feeling relieved rises refers to depends on the bearing bore diameter of institute's positioning model; The positioning tube head has negative thread and the centering external screw thread that refers to afterbody that rises to match, afterbody is put into effect embossing, and negative thread is arranged, match with the external screw thread of radius stay afterbody, the head of radius stay is a taper locating tip, and the external diameter of head and the centering internal diameter that refers to through hole that rises matches, and the external diameter at the middle part of radius stay and the internal diameter of positioning tube match, the radius stay afterbody is put into effect embossing, and the external screw thread that matches with the positioning tube afterbody is arranged; Slip shape tapered sleeve tube is that an inside has and the match conical bush of through hole of positioning tube external diameter, and at the afterbody embossing.
Owing to adopted above-mentioned technical solution, this centralized positioning device can be according to the requirement in the clutch spindle front bearing endoporus aperture of different vehicle types, the centering of the disposing corresponding external diameter finger that rises.So be applicable to various types of self-propelled vehiclees.Characteristics such as the scheme that the utlity model has is scientific and reasonable, simple in structure, the location is reliable, practical.
Four, description of drawings:
Below in conjunction with drawings and Examples the utility model is described in further detail:
Accompanying drawing is the structural representation of embodiment of the present utility model;
Indicate in the accompanying drawing: finger 1, slip conical bush 2, positioning tube 3, the radius stay 4 of rising of feeling relieved;
Five, the specific embodiment:
The centralized positioning device mainly by centering rise refer to 1, slip conical bush 2, positioning tube 3, radius stay 4 form, the centering finger center of rising has a big ladder hole of little tail, head has a plurality of well-distributed grooves, form the metal flap, afterbody has external screw thread, match with the head negative thread of positioning tube 3, embossing is put into effect at the middle part, and centering is risen and referred to that 1 head diameter depends on the bearing bore diameter of institute's positioning model; Positioning tube 3 heads have negative thread and the centering external screw thread that refers to 1 afterbody that rises to match, afterbody is put into effect embossing, and negative thread is arranged, match with the external screw thread of radius stay 4 afterbodys, the head of radius stay 4 is taper locating tips, and the external diameter of head and the centering internal diameter that refers to 1 through hole that rises matches, and the internal diameter of the external diameter at the middle part of radius stay 4 and positioning tube 3 matches, radius stay 4 afterbodys are put into effect embossing, and the external screw thread that matches with positioning tube 3 afterbodys is arranged; Slip conical bush 2 is that an inside has and the match conical bush of through hole of positioning tube 3 external diameters, afterbody embossing.
During use, slip conical bush 2 is enclosed within on the positioning tube 3, the centering that matches with the maintenance vehicle is risen and is referred to that 1 screws in the apical head of positioning tube 3, radius stay 4 is screwed in by positioning tube 3 afterbodys, during beginning, do not screw, when the centering of center steady arm rise refer to 1 insert the front bearing endoporus of clutch spindle after, radius stay 4 can be screwed, the feasible centering of the taper locating tip of radius stay 4 heads is risen and is referred to 1 metal lobe spreading, make it firmly be fixed on the front bearing endoporus of clutch spindle, finish centralized positioning work.
