Abstract
The utility model belongs to the technical field of deep hole machining and relates to a conveniently-disassembled bearing seat. During deep hole machining, when workpieces of different hole diameters are machined, corresponding gun drills and rubber seals are required for being replaced, all screws at the connection between a bearing seat and a drill rod rack are required for being dismounted firstly, the bearing seat is pulled out of the drill rod rack, and hexagon socket head cap screws are required for being all removed, so that the operation is inconvenient. The conveniently-disassembled bearing seat comprises the bearing seat and holes formed in the bearing seat, wherein the holes are of gourd-shaped structures and comprise small ends and big ends, the diameter of the small ends is smaller than that of the screws, the diameter of the big ends is greater than that of the screws, the holes are uniformly distributed in the bearing seat along the same circumference, and the small ends of the holes are arranged along the rotating direction of the bearing seat. The holes are formed in the bearing seat, so that the screws are not required for being all removed, the operation is easy, and the operating time is shortened.
Description
Technical field
The utility model belongs to the deep hole processing technical field, relates to a kind of easy-to-dismount bearing support.
Background technique
In deep hole processing, when processing the workpiece in different apertures, need to change corresponding drill gun and rubber seal, rack for rods is by hexagon socket cap head screw bearing support and rack for rods to be connected as a single entity, and when needs are changed drilling rod and shock absorbing sleeve, need unload all screws in step and rack for rods joint earlier, then bearing support is pulled out from rack for rods, and making drill gun leave rack for rods by the gap on the rack for rods, this structure needs hexagon socket cap head screw is all unloaded, operation inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of easy to operate bearing support that screw is all unloaded of not needing.
The technological scheme that the utility model adopts is, a kind of easy-to-dismount bearing support, comprise bearing support and the hole that is arranged on the bearing support, it is characterized in that: described hole is " cucurbit shape " structure, comprise small end and big end, the diameter of described small end is less than the screw head diameter dimension, and the diameter of described big end is greater than the screw head diameter dimension, described hole is evenly distributed on the bearing support along same circumference, and the small end in described hole arranges along the bearing support sense of rotation.
Compared with prior art, the beneficial effects of the utility model are: the hole that arranges on this bearing support does not need screw is all unloaded, and easy operating has shortened the operating time.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1. bearing support, 2. hole, 3. end, 4. small end, 5. screw greatly.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1, a kind of easy-to-dismount bearing support, comprise bearing support 1 and the hole 2 that is arranged on the bearing support 1, it is characterized in that: described hole 2 is " cucurbit shape " structure, comprise small end 4 and big end 3, the diameter of described small end 4 is less than the screw head diameter dimension, and the diameter of described big end 3 is greater than the screw head diameter dimension, described hole 2 is evenly distributed on the bearing support 1 along same circumference, and the small end 4 in described hole 2 is along bearing support 1 sense of rotation setting.
Principle of the present utility model is: when needing to change drilling rod and shock absorbing sleeve, need earlier screw to be unscrewed, rotating shaft holder 1 then, make screw head be in the big end 3 of bearing support 1, bearing support 1 is taken out from rack for rods, when mounted, screw is passed the big end of bearing support 1, rotatingshaft bearing 1 makes screw be positioned at small end then, tightens screw then and gets final product.
In sum, when operation, do not need screw is all unloaded, easy operating has shortened the operating time.
