Abstract
The utility model relates to a positioning pressing sheet for machining of a cage pocket, wherein the positioning pressing sheet (2) fixes the cage (6) on the dividing head (5) of a drilling machine by a fastening bolt (1); the outer diameter of the positioning pressing sheet is smaller than or equal to that of the cage; the center of the positioning pressing sheet is provided with a semicircular small hole (3); the diameter of the semicircular small hole matches that of the screw rod on the fastening bolt, and the opening end of the semicircular small hole is connected with an over-half circular large hole (4) which has a diameter greater than that of the head of the fastening bolt. The semicircular small hole has positioning function, while the fastening bolt can fix the cage on the dividing head of the drilling machine through screwing after the positioning, so as to perform the drilling process of the cage pocket. During the machining, the cage is less likely to loosen, which significantly reduces the time of machining a pocket for a single cage, increases the machining efficiency of the cage, and ensures the machining precision of the cage.
Description
Technical field
The utility model belongs to technical field of bearing processing, especially a kind of location compressing tablet that is used for the processing of retainer pocket hole.
Background technology
At present, add man-hour in retainer pocket hole, fastening bolt is fixed on retainer on the drilling machine dividing head through pad, compressing tablet, and the aperture on the compressing tablet is greater than the fastening bolt head diameter, and the jagged and diameter of gasket strip approximates the diameter of screw rod on the fastening bolt.
Drilling finishes, and pad and compressing tablet is taken off from fastening bolt one by one could take out retainer earlier, has prolonged single retainer pocket hole process time, has influenced working (machining) efficiency.Directly compressing its indentation, there of retainer with fastening bolt with the pad that has breach is simultaneously thrust by drill bit easily.
In addition, also can directly compress retainer with fastening bolt and pad, but the seal face between fastening bolt head and the pad is very little, becoming flexible appears in retainer easily in the process, has influenced the machining accuracy of retainer.
Summary of the invention
For overcoming above-mentioned defective, the utility model has designed a kind of location compressing tablet that is used for the processing of retainer pocket hole,
This location compressing tablet unites two into one the function of above-mentioned pad and compressing tablet; Through location compressing tablet and fastening bolt retainer is fixed on the drilling machine dividing head; When guaranteeing the retainer machining accuracy, significantly reduce pocket hole process time, improved the working (machining) efficiency of retainer.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of location compressing tablet that is used for the processing of retainer pocket hole; This location compressing tablet is fixed on retainer on the drilling machine dividing head through fastening bolt; The external diameter of the external diameter≤retainer of location compressing tablet, the center of compressing tablet is provided with semicircle aperture in the location, the diameter of screw rod coupling on the diameter of said semicircle aperture and the fastening bolt; Openend at said semicircle aperture is connected with most round macropores, the diameter of said most round macropores＞fastening bolt head diameter.
Owing to adopt technical scheme as stated, the utility model produces following beneficial effect:
1, pad in the background technology and compressing tablet are substituted by the location compressing tablet; Just can retainer be fixed on the drilling machine dividing head through fastening bolt; The fastening bolt head increases with the seal face of location compressing tablet, and retainer is not prone to loosening phenomenon in the process, has significantly reduced the pocket hole process time of single retainer; Improve the working (machining) efficiency of retainer, guaranteed the machining accuracy of retainer.
2, the location compressing tablet is simple in structure, easy to use.
Description of drawings
Fig. 1 is the mounting structure sketch map of the utility model;
Fig. 2 is the compressing tablet structural representation.
Among the above-mentioned figure: 1-fastening bolt; 2-location compressing tablet; 3-semicircle aperture; 4-mostly round macropores; 5-drilling machine dividing head; 6-retainer.
The specific embodiment
The utility model is a kind of location compressing tablet that is used for the processing of retainer pocket hole.
In conjunction with Fig. 1,, location compressing tablet 2 is fixed on retainer 6 on the drilling machine dividing head 5 through fastening bolt 1.
In conjunction with Fig. 2; The external diameter of the external diameter≤retainer 6 of location compressing tablet 2; The center of compressing tablet 2 is provided with semicircle aperture 3 in the location; The diameter of screw rod coupling on the diameter of said semicircle aperture 3 and the fastening bolt 1 is connected with most round macropores 4, the diameter of said most round macropores 4＞fastening bolt head diameter at the openend of said semicircle aperture 3.
During installation; Retainer 6 basal planes contact with drilling machine dividing head 5 end faces; Fastening bolt 1 is screwed on drilling machine dividing head 5 centre bores all the time; After the most round macropore 4 of location compressing tablet 2 passed fastening bolt 1 head, semicircle aperture 3 is being dropped on fastening bolt 1 screw rod, because the diameter of screw rod matees on the diameter of semicircle aperture 3 and the fastening bolt 1; In fact semicircle aperture 3 has positioning action, and tightening fastening bolt 1 behind the location can be fixed on the drilling machine dividing head 5 retainer 6 to carry out the Drilling Operations in retainer pocket hole.After machining, unclamp fastening bolt 1, unload location compressing tablet 2, just can take out retainer 6, accomplish the processing tasks in single retainer pocket hole through most round macropores 4.
Pad in the background technology and compressing tablet are substituted by location compressing tablet 2; Just can retainer 6 be fixed on the drilling machine dividing head 5 through fastening bolt 1; Fastening bolt 1 head increases with the seal face of location compressing tablet 2, and retainer 6 is not prone to loosening phenomenon in the process, has significantly reduced the pocket hole process time of single retainer; Improve the working (machining) efficiency of retainer, guaranteed the machining accuracy of retainer.
Claims (1)
1. one kind is used for the location compressing tablet that retainer pocket hole processes; This location compressing tablet (2) is fixed on retainer (6) on the drilling machine dividing head (5) through fastening bolt (1); It is characterized in that: the external diameter of the external diameter≤retainer (6) of location compressing tablet (2); Center at location compressing tablet (2) is provided with semicircle aperture (3); The diameter of said semicircle aperture (3) and fastening bolt (1) are gone up the diameter coupling of screw rod, are connected with most round macropores (4), diameter＞fastening bolt (1) head diameter of said most round macropores (4) at the openend of said semicircle aperture (3).
