[0001] The utility model relates to the technical field of tooling fixtures, in particular to a fixture switching device. Background Art

[0002] In machining, turning is suitable for machining rotating surfaces. Most workpieces with rotating surfaces can be machined using turning methods, such as internal and external cylindrical surfaces, internal and external conical surfaces, end faces, grooves, threads, and rotating formed surfaces. Eccentric parts are a very common type of workpiece in machining. Eccentric parts refer to parts where the axes of the outer circle and inner hole are parallel but not coincident, with a certain distance between the two axes. This distance between the two parallel axes is called the eccentric distance. The machining of eccentric parts usually requires some auxiliary tooling to complete the eccentric turning.

[0003] In the prior art, the eccentric position is mostly adjusted by using eccentric gauge blocks of various specifications. On the one hand, it is necessary to always have eccentric gauge blocks of various specifications on hand, which increases the cost of use and is easy to lose. On the other hand, during the adjustment process, different eccentric gauge blocks need to be replaced multiple times to determine the eccentric position, which takes a long time and is cumbersome to adjust. In addition, the locking structure is set on the plane where the workpiece to be processed is installed, and a part of the locking structure is blocked by the workpiece to be processed, resulting in an inability to lock, affecting the use effect. Utility Model Content

[0004] The purpose of the present invention is to solve the problems in the prior art that the adjustment process takes a long time and the locking structure may be blocked by the workpiece to be processed, resulting in the inability to lock, and to propose a clamp adapter device.

The second positioning holes 201 and the first positioning hole 101 are convenient for adjusting the initial position of the adapter plate 2 so that the axis of the adapter plate 2 coincides with the axis of the base 1, thereby improving the use effect. A mounting groove 202 for mounting a fixture is provided on the adapter plate 2. The mounting groove 202 is provided with two to six groups, preferably four groups, and the four groups are evenly distributed on the end face of the adapter plate 2, and the four groups of mounting grooves 202 are all T-shaped structures, which are convenient for installing and fixing the processing fixture.

The axes of the measuring rods coincide, and the adapter plate 2 can be square or round. Here we prefer a round one, and in order to facilitate the installation of the screw rod 4 and the measurement of the micrometer 8, we have planes on both ends of the adapter plate 2. The two sets of planes are symmetrically arranged and parallel to each other. The axis of the screw rod 4 and the extension line of the axis of the measuring rod are perpendicular to the two sets of planes respectively. One end of the screw rod 4 is rotatably connected to one set of planes, and the measuring rod of the micrometer 8 is offset against the other set of planes; a slider 6 is slidingly arranged in the base 1. Here, we have a limiting groove 102 on the base 1, and the slider 6 is slidably connected in the limiting groove 102. The limiting groove 102 is a T-shaped structure, and the slider 6 is also a T-shaped structure, and we prefer to set the limiting groove 102 There are two groups, and they are symmetrically distributed. When in use, the sliding direction of the slider 6 is consistent with the sliding direction of the adapter plate 2. A connecting groove 204 is provided on the outer wall of the adapter plate 2. There are also two groups of connecting grooves 204, corresponding to the positions of the limit grooves 102. Screws 7 are respectively provided in the two groups of connecting grooves 204. One end of the screw 7 is threadedly connected to the slider 6, and an adjustment plate 701 is fixedly provided at the other end of the screw 7. The bottom of the adjusting plate 701 is abutted against the inner bottom of the connecting groove 204. By tightening the screw 7, the bottom of the adjusting plate 701 is abutted against the inner bottom of the connecting groove 204, so that the adapter plate 2 can be fixed on the base 1 to prevent the adapter plate 2 from moving during use, resulting in malfunction.

[0029] During use, the eccentricity can be quickly determined through the screw rod 4 and the micrometer 8, that is, the eccentricity of the adapter plate 2 relative to the base 1 can be quickly adjusted, thereby realizing the adjustment of the eccentricity of the parts on the adapter plate 2, facilitating the subsequent eccentric processing, and the use process is simple, convenient, and easy to operate.

[0031] Reference Figure 1-Figure 3 A guide block 5 is fixedly provided on the base 1. Here, we fix the guide block 5 to the base 1 by bolts, and positioning pin holes are respectively opened on the guide block 5 and the base 1, which can improve the installation speed and guiding accuracy of the guide block 5 and improve the use effect.

[0034] 8 and 8. When the workpiece is to be machined, the guide plate 2 is tightened and the eccentricity is improved. The screw 4 is driven by the knob 401 to rotate, and the adapter plate 2 is driven to slide along the guide block 5. At the same time, the dial indicator 8 is observed and the adapter plate 2 is adjusted to the required eccentricity. Finally, the screw 7 is tightened to ensure that the adapter plate 2 is fixed on the base 1 without any looseness. The clamping process is completed and the eccentricity processing can be started.
