Abstract
The utility model relates to a positioning disk technical field especially relates to central positioning disk with adjustable, current positioning disk simple structure can not solve the positioning disk and install the too big problem of beating on the equipment main shaft, central positioning disk with adjustable, including the anchor clamps body, it has the internal screw thread locking locating hole to set up a plurality of inner walls on the anchor clamps body bottom circumferencial direction, each locking locating hole department sets up the locking part who has with the external screw thread, closely cooperates with the equipment main shaft through each locking part, has good development prospect in positioning disk technical field.
Description
Technical Field
The utility model relates to a positioning disk technical field especially relates to central positioning disk with adjustable.
Background
In the processing of automobile brake assembly, will install the work piece on a central positioning dish, the central positioning dish is connected for little clearance fit with the equipment main shaft now, beat poorly in the rotation process, usually be greater than 0.05, thereby it is big to cause the machined surface of processing work piece to beat, current positioning disk structure, it is connected with the little clearance fit location of hole axle directly, there is the location inaccurate, if the beat of terminal surface and circumference is out of tolerance, also can not adjust, the precision is not high, a series of problems such as inclined to stop after the loading, the host computer factory is unsatisfactory, also cause the loss for the company, consequently designed an adjustable central positioning dish, solve this type of problem betterly.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned condition, for overcoming prior art's defect, the utility model provides a central positioning dish with adjustable solves positioning disk and the poor too big and not adjustable problem of equipment main shaft beating.
The adjustable central positioning disc comprises a clamp body, wherein the upper part of the clamp body is provided with a positioning hole which is in interference fit with a corresponding equipment spindle, so that axial runout is only related to runout of the corresponding equipment spindle, a plurality of locking positioning holes with internal threads on inner walls are arranged in the circumferential direction of the lower part of the clamp body, a locking part with external threads is arranged at each locking positioning hole, the clamp body is sleeved on the equipment spindle through a central hole, locking is realized by adjusting the distance between each locking part and the equipment spindle, the runout of the clamp body reaches the minimum range, the mounting precision of the clamp body is improved, and the processing precision of a processed workpiece is improved.
Furthermore, the locking positioning holes are arranged at equal intervals in the circumferential direction of the clamp body so as to ensure that the surface of the clamp body is flat and stable.
Furthermore, the number of the locking positioning holes is four, and the locking positioning holes are adjusted in four directions respectively.
Furthermore, the end face of one end of each locking component, which is connected with the locking positioning hole, is arc-shaped, so that the locking component is tightly matched with the main shaft of the equipment to prevent sliding.
The technical effect of the utility model is that, the anchor clamps body closely cooperates through each locking part and equipment main shaft, makes the specific beat of anchor clamps reach minimum scope, improves the specific installation accuracy of anchor clamps to improve the machining precision of processing work piece, easily preparation moreover.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. 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.
It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicating the directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The first embodiment is as follows: the adjustable central positioning disc is shown in figures 1 to 3 and comprises a clamp body 1, wherein a positioning hole is formed in the upper portion of the clamp body 1 and is in interference fit with a corresponding equipment spindle, so that axial runout is only related to runout of the corresponding equipment spindle, a plurality of locking positioning holes 3 with internal threads on inner walls are formed in the circumferential direction of the lower portion of the clamp body 1, locking parts 2 with external threads are arranged at the locking positioning holes 3, the clamp body 1 is sleeved on the equipment spindle through a central hole, locking is achieved by adjusting the distance between each locking part and the equipment spindle, the runout of the clamp body 1 is enabled to reach the minimum range, the mounting accuracy of the clamp body 1 is improved, and the machining accuracy of a machined workpiece is improved.
Example two: on the basis of the first embodiment, the locking positioning holes 3 are arranged at equal intervals in the circumferential direction of the fixture body 1 to ensure that the surface of the fixture body is flat and stable, four locking positioning holes 3 are respectively adjusted in four directions, and the end face of one end, connected with the locking positioning holes 3, of each locking component 2 is arc-shaped to realize tight fit with a main shaft of equipment and prevent sliding.
The technical effect of the utility model is that, the anchor clamps body closely cooperates through each locking part and equipment main shaft, makes the specific beat of anchor clamps reach minimum scope, improves the specific installation accuracy of anchor clamps to improve the machining precision of processing work piece, easily preparation moreover.
The present invention has been described in detail with reference to the specific embodiments and examples, but these should not be construed as limitations of the present invention. Numerous variations and modifications can be made by those skilled in the art without departing from the principles of the invention, which should also be considered as within the scope of the invention.
