Abstract
The utility model relates to a cylinder excircle accurate positioning device, which comprises an elastic expansion sleeve, an outer fixed sleeve, a threaded pull rod, a handle and a connecting plate; the outer fixing sleeve is arranged on the connecting plate, the threaded pull rod is in threaded connection with the center inside the outer fixing sleeve, one end of the threaded pull rod is connected with the elastic expansion sleeve, and the other end of the threaded pull rod penetrates through the connecting plate to be connected with the handle. When the handle is rotated, the threaded pull rod and the elastic expansion sleeve are driven to rotate together, and the elastic expansion sleeve and the outer fixing sleeve are in sliding fit with each other, so that the elastic expansion sleeve clamps a product to move downwards, and the elastic expansion sleeve contracts towards the inner center under the action of the conical surface of the outer fixing sleeve until the outer circle of the product is compressed, and the outer circle of the product is positioned and clamped. The accurate positioner of cylinder excircle can not influence the precision of axle center location because of the error of cylinder product external diameter size.
Description
Technical Field
The utility model relates to a detection instrument of car axle class product belongs to automotive machinery.
Background
Parts all need to be fixed a position among the automobile mold production, however in some parts that use circular part as the representative, part and positioning die always can produce the clearance, lead to the part precision can not guarantee, consequently urgently need a novel positioner to solve this problem.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a quick simple accurate positioner of cylinder increases the speed of location and the simplicity of operation when guaranteeing positioning accuracy.
In order to solve the technical problem, the utility model adopts the following technical scheme: an accurate positioning device for the excircle of a cylinder comprises an elastic expansion sleeve, an outer fixing sleeve, a threaded pull rod, a handle and a connecting plate; the outer fixing sleeve is arranged on the connecting plate, the threaded pull rod is in threaded connection with the center inside the outer fixing sleeve, one end of the threaded pull rod is connected with the elastic expansion sleeve, and the other end of the threaded pull rod penetrates through the connecting plate to be connected with the handle.
Further, the outer fixing sleeve comprises an upper fixing sleeve and a lower fixing sleeve; the elastic expansion sleeve is matched with the conical surface of the upper fixed sleeve in a sliding way; the lower fixing sleeve is arranged on the connecting plate, and the threaded pull rod is in threaded connection with the lower fixing sleeve.
Compared with the prior art, the beneficial effects of the utility model reside in that: the elastic expansion sleeve is embedded in the outer fixed sleeve, and the elastic expansion sleeve and the outer fixed sleeve are in conical surface sliding fit, so that when the handle is rotated, the threaded pull rod and the elastic expansion sleeve are driven to rotate together. The accurate positioning device for the outer circle of the cylinder does not influence the positioning precision of the shaft center due to the error of the outer diameter size of a cylinder product; the rapid positioning and pressing can be realized on the checking fixture; greatly reducing the working strength and the skill requirement of the detection personnel.
The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.
Drawings
Fig. 1 is a schematic structural diagram according to an embodiment of the present invention.
Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, a cylindrical outer circle accurate positioning device according to a preferred embodiment of the present invention includes an elastic expansion sleeve 1, an outer fixing sleeve 2, a threaded pull rod 3, a handle 5 and a connecting plate 6; the outer fixed sleeve 2 is arranged on the connecting plate 6, the threaded pull rod 3 is in threaded connection with the center inside the outer fixed sleeve 2, one end of the threaded pull rod 3 is connected with the elastic expansion sleeve 1, and the other end of the threaded pull rod penetrates through the connecting plate 6 to be connected with the handle 5.
Further, the outer fixing sleeve 2 comprises an upper fixing sleeve and a lower fixing sleeve; the elastic expansion sleeve 1 is matched with the conical surface of the upper fixed sleeve in a sliding way; the lower fixing sleeve is arranged on the connecting plate 6, and the threaded pull rod 3 is in threaded connection with the lower fixing sleeve.
The utility model discloses the operation method that accurate positioner of cylinder excircle was in does, put cylinder product 4 location end in the tight cover 1 of elasticity inflation of accurate positioner of cylinder excircle, clockwise rotation handle 5, screw thread pull rod 3 downstream to drive the tight cover 1 lapse of elasticity inflation, because the tight cover 1 of elasticity inflation is the conical surface sliding fit with outer fixed cover 2, so, the tight cover of elasticity inflation contracts to the inner center simultaneously when slipping down, until compressing tightly the excircle of cylinder product 4, the excircle location of messenger cylinder product 4 is pressed from both sides tightly.
In conclusion, the elastic expansion sleeve 1 is embedded in the outer fixing sleeve 2, and the elastic expansion sleeve 1 and the outer fixing sleeve 2 are in conical surface sliding fit, so that when the handle 5 is rotated, the threaded pull rod 3 and the elastic expansion sleeve 1 are driven to rotate together, and as the elastic expansion sleeve 1 and the outer fixing sleeve 2 are in conical surface sliding fit, the elastic expansion sleeve 1 clamps a product to move downwards, and under the action of the conical surface of the outer fixing sleeve 2, the elastic expansion sleeve 1 contracts towards the inner center until the outer circle of the cylindrical product 4 is compressed, so that the outer circle of the cylindrical product 4 is positioned and clamped. The accurate positioning device for the outer circle of the cylinder does not influence the positioning precision of the shaft center due to the error of the outer diameter of the cylindrical product 4; the rapid positioning and pressing can be realized on the checking fixture; greatly reducing the working strength and the skill requirement of the detection personnel.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention.
