Description

Technical Field

[0001] The utility model relates to the technical field, in particular to an adapting fixture for shaft processing. Background Art

[0002] Traditionally, when processing (polishing, grinding, grooving, etc.) rod-shaped objects such as shafts, the limiting effect is achieved by clamping the ends. In the polishing or grinding process, the clamping structure at the end is also connected to a rotating drive source, and the rotating device drives the fixture to rotate, so that the shaft clamped by the fixture rotates accordingly.

[0003] However, for some shafts made of soft materials, even if they are clamped at the ends, eccentricity may occur during high-speed rotation or when the processing equipment is in pressure contact. In addition, the center points of some longer shafts may drop eccentrically after clamping, resulting in inaccurate processing. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, an adapter fixture for shaft processing includes an arc-shaped plate 1. There are two arc-shaped plates 1. Both ends of the arc-shaped plate 1 are provided with a fixing tube 3. The arc-shaped plate 1 is located at the position of the fixing tube 3 and a mounting hole 2 is drilled through it. The fixing tube 3 is respectively penetrated through the mounting hole 2 and then welded to be connected. A hydraulic rod 4 is fixed to the bottom end of the fixing tube 3. A push rod 5 is fixed to the output end of the hydraulic rod 4. A U-shaped seat 6 is fixed to the top of the push rod 5. A clamping roller 7 is rotatably connected to the inside of the U-shaped seat 6.

[0021] Specifically, support frames 12 are provided at both outer ends of the arc-shaped plates 1, and the outer walls of the arc-shaped plates 1 are fixedly connected to the support frames 12 respectively. A mounting seat 13 is provided at the bottom between the support frames 12, and the bottom of the support frame 12 is fixedly connected to the top of the mounting seat 13 respectively, so as to fix the device.

[0022] Specifically, the top rod 5 is slidably connected to the fixed tube 3 respectively, and sliding rods 9 are fixed to both ends of the U-shaped seat 6 close to the top rod 5. Mounting holes 11 are drilled through both ends of the arc plate 1 located at the mounting hole 2, and fixed tubes 10 are inserted into the mounting holes 11. The arc plate 1 is welded to the fixed tube 10, and the sliding rods 9 are respectively inserted into the fixed tubes 10 at matching positions and slidably connected thereto, so that the movement of the U-shaped seat 6 is more stable.

[0023] Specifically, the outer wall of the clamping roller 7 is provided with an electromagnet 8 to achieve a double limiting effect.

[0024] Working principle:

[0025] The four clamping rollers 7 are clamped at the four corners, and the position where the workpiece is supported is located in the center. The hydraulic rod 4 in the fixed tube 3 can push out the push rod 5, so that the U-shaped seat 6 can drive the clamping rollers 7 to support, clamp and limit the shaft rod, avoiding eccentricity during processing, and can be used as a supporting clamp device;

[0026] When the shaft needs to be stationary during processing, the clamping roller 7 first clamps and limits the shaft. At this time, the opening of the electromagnet 8 can directly magnetically limit the shaft rod, achieving a double limit effect.

[0027] The circuits, electronic components and control modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.
