Detailed Description
In order to facilitate an understanding of the present application, a more complete description of the present application will now be provided with reference to the relevant figures. Examples of the present application are given in the accompanying drawings. This application may, however, be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," and/or the like, specify the presence of stated features, integers, steps, operations, elements, components, or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or groups thereof.
Example 1
A grinding machine clamping structure suitable for pipe rods with different diameters comprises a grinding machine jig 1, a clamping sleeve 2 and a pipe rod 4. The front side of the grinding machine tool 1 is provided with a mounting groove. The clamping sleeve 2 is detachably arranged in the mounting groove, and the outer side wall of the clamping sleeve 2 is in interference fit with the inner side wall of the mounting groove. The inner diameter of the clamping sleeve 2 is matched with the shaft diameter of the pipe rod 4, and the end part of the pipe rod 4 is installed in the clamping sleeve 2 in an interference manner.
In this embodiment, only one set of grinding machine tool 1 is designed according to the general specification, and then a plurality of clamping sleeves 2 with different specifications are manufactured according to different diameters of the material pipe rod 4 in the production process. When in use, the process production provides the diameter specification of the pipe rod 4, the warehouse checks whether the clamping sleeve 2 is proper, and the clamping sleeve 2 with corresponding specification is not additionally produced at any time.
According to the embodiment, by arranging the replaceable clamping sleeve 2, grinding of pipe rods 4 with different diameters can be adapted only by using one set of grinding machine jig 1, the preparation time of the tool jig is shortened, and the cost of the jig is reduced.
Example two
The difference between this embodiment and the first embodiment is that the clamping sleeve 2 includes a plurality of circumferentially distributed clamping pieces 21, each two adjacent clamping pieces 21 are connected by an elastic member 22, and the elastic member 22 is in a compressed state, so that the entire clamping sleeve 2 has a tendency to expand outwards.
The inner side walls of the clamping pieces 21 are tightly attached to the pipe rod 4, and the outer side walls of the clamping pieces 21 are inclined planes which gradually protrude outwards from back to front. The inner diameter of the installation groove gradually increases from the rear to the front, and the slope of the inner side wall of the installation groove is equal to the slope of the outer side wall of the holding piece 21.
The front side of the grinding machine tool 1 is provided with a cover body 3, and the cover body 3 butts against the front end of the clamping piece 21. The cover body 3 is connected with the outer side wall of the grinding machine tool 1 through threads, and the cover body 3 can move forwards and backwards through unscrewing or tightening the cover body 3. The center of the cover body 3 is provided with a mounting hole 3111, and the mounting hole 3111 is larger in diameter than the inner diameter of the grip housing 2 for passing the pipe rod 4 through the mounting hole 3111.
By tightening the cover body 3, the cover body 3 moves backwards, and the clamping sleeve 2 can be pressed backwards, so that the inner diameter of the clamping sleeve 2 is reduced. By unscrewing the cover 3, the cover 3 is moved forward, the elastic member 22 is stretched to expand the grip sleeve 2, so that the grip sleeve 2 is moved forward and the inner diameter of the grip sleeve 2 is increased. Therefore, the grinding machine tool 1 can be used for grinding pipe rods 4 with different diameters by only one set without changing the clamping sleeve 2.
When the pipe rod 4 needs to be replaced, the clamping sleeve 2 can automatically loosen the pipe rod 4 only by unscrewing the cover body 3, and the operation is simple and convenient.
The foregoing is only illustrative of the present utility model and is not to be construed as limiting thereof, but rather as various modifications, equivalent arrangements, improvements, etc., within the spirit and principles of the present utility model.
