Clamp a has several bolts a, and clamp b has bolts b. The beneficial effects of this utility model are: by placing the shaft in the groove of the base, clamps a and b limit its movement; and by adjusting the length of bolts a and b extending into the corresponding clamps according to the shaft diameter, bolts a and b fix the side of the workpiece, thereby avoiding applying force to the end of the workpiece and causing end concavity, ensuring subsequent fitting accuracy.

Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a fixture for shaft machining. Background Technology

[0002] Existing fixtures have poor adaptability to shaft diameters. If the shaft diameter of the workpiece is different, a single fixture cannot clamp it and a corresponding fixture needs to be replaced, which is extremely inconvenient. Moreover, the fixtures clamp such shafts by directly applying force to the end of the workpiece with a screw. This method is prone to high stress concentration at the contact point, causing micro-deformation (end concavity) or surface scratches (especially for soft or thin-walled shafts), affecting the subsequent fitting accuracy. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fixture for shaft machining.

[0004] The purpose of this utility model is achieved through the following technical solution: a fixture for shaft machining, including a base, a groove is provided on the upper end of the base, and a clamp a and a clamp b are also provided on the base. The clamp a is located on one side of the clamp b. A plurality of bolts a are provided on the clamp a, and bolts b are provided on the clamp b.

[0005] Preferably, there are two bolts a, which are inclined on the clamp a and symmetrically distributed on the clamp a.

[0006] Preferably, there is one bolt b, which is located in the middle of the clamp b and between the two bolts a.

[0007] Preferably, the ends of bolts a and b are provided with adhesive films.

[0008] Preferably, the base has a groove on its side, and the inner sides of clips a and b are provided with sliders that slide in cooperation with the groove.

[0009] Preferably, the inner side of the chute is provided with an anti-reverse groove.

[0010] This utility model has the following advantages: The utility model places the shaft in the groove of the base, so that the clamps a and b limit its position. According to the shaft diameter, the length of bolts a and b extending into the corresponding clamps is adjusted so that bolts a and b fix the side of the workpiece, thereby avoiding the application of force to the end of the workpiece, causing the end to be recessed, and ensuring the subsequent fitting accuracy.

[0017] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] In this embodiment, as Figure 1 As shown, a fixture for shaft machining includes a base 1 with a groove 2 at its upper end. Clamps a3 and b6 are also provided on the base 1, with clamp a3 located on one side of clamp b6. Clamp a3 has several bolts a4, and clamp b6 has bolts b5. The shaft is placed in the groove 2 of the base 1, limiting its position. The lengths of bolts a4 and b5 extending into the corresponding clamps are adjusted according to the shaft diameter, fixing the side of the workpiece to prevent stress on the end of the workpiece and thus avoiding end-end concavity, ensuring subsequent fitting accuracy. In this embodiment, the groove 2 is a V-groove.

[0020] Furthermore, there are two bolts a4, which are obliquely arranged on clamp a3 and symmetrically distributed on clamp a3. Further still, there is one bolt b5, located in the middle of clamp b6, between the two bolts a4. Specifically, the symmetrical distribution of bolts a4 on clamp a3 and the location of bolt b5 between the two bolts a4 allow for uniform clamping of the workpiece's side surface, restricting workpiece movement and keeping it stationary during processing. Preferably, the ends of bolts a4 and b5 are provided with adhesive strips. Specifically, the main function of the adhesive strips is to prevent the ends of bolts a4 and b5 from damaging the side surface of the workpiece.

[0021] In this embodiment, a sliding groove 7 is provided on the side of the base 1, and sliders that slide in conjunction with the sliding groove 7 are provided on the inner sides of the clamps a3 and b6. Furthermore, an anti-reverse groove 8 is provided on the inner side of the sliding groove 7. Specifically, the main function of the sliding groove 7 is to facilitate the movement of the clamps a3 and b6, thereby clamping the workpiece in a suitable area.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
