Description

Technical Field

[0001] The present application relates to the technical field of surface grinders, and more specifically, to a surface grinder fixture. Background Art

[0002] Surface grinder fixtures are devices used to fix and clamp workpieces. They are mainly used in surface grinding processes to ensure that the workpiece maintains a stable position and orientation during the grinding process. These fixtures usually have adjustable clamping force and clamping angle to accommodate workpieces of different shapes and sizes, ensuring the accuracy and consistency of the grinding effect.

[0003] However, the existing surface grinder fixtures can only provide a simple clamping function. When the end faces of multiple cylindrical thin metal rods need to be evenly ground, the existing fixtures cannot firmly fix them together, resulting in gaps between the cylindrical thin metal rods. In this case, shaking may occur during the grinding process, thereby affecting the final grinding accuracy and consistency.

[0004] In view of this, we propose a surface grinder fixture. Utility Model Content

[0020] Reference Figure 1 and Figure 2 A threaded hole 4 is provided on one side of the upper end surface of the adjusting plate 2, and a pair of through holes 5 are provided on the other side of the upper end surface of the adjusting plate 2. A threaded rod 6 is fixedly connected to one side of the upper end surface of the fixed base plate 1, and the threaded rod 6 is rotatably connected to the threaded hole 4 through a thread. A pair of limiting rods 7 are fixedly connected to the other side of the upper end surface of the fixed base plate 1, and the limiting rods 7 pass through the through holes 5. A spring 8 is provided on the periphery of the limiting rod 7, and the two ends of the spring 8 are respectively fixedly connected to the fixed base plate 1 and the adjusting plate 2. The spring 8 plays a good supporting role, making the device more stable. The threaded rod 6 can be rotated to adjust the height of the adjusting plate 2, so that the fixing clamp 3 can clamp cylindrical thin metal rods of different lengths.

[0021] Reference Figure 3 The upper and lower end surfaces of the extrusion strip 15 are both provided with a limiting slide groove 17, and a pair of limiting sliders 18 are slidably connected inside the limiting slide groove 17. The end surface of the limiting slider 18 close to the limiting groove 14 is fixedly connected with an extension block 19, and the extension block 19 is located inside the limiting groove 14, which plays a good limiting role and prevents the extrusion strip 15 from falling off from the sliding groove 13.

[0022] Working principle: When in use, put all the cylindrical thin metal sticks that need to be polished into the two fixing clamps 3, the cylindrical thin metal stick passes through the connecting port 9, and the bottom falls on the fixed bottom plate 1, and the threaded rod 6 is rotated. The rotation of the threaded rod 6 drives the adjustment plate 2 and the fixing clamp 3 on the adjustment plate 2 to move synchronously, and the outer spring 8 of the limit rod 7 is unfolded until the adjustment plate 2 moves to the upper end of the cylindrical thin metal stick, and the upper end of the cylindrical thin metal stick is exposed from the fixing clamp 3. The staff can stop rotating the threaded rod 6, and then the staff rotates the threaded moving rod 11. The rotation of the threaded moving rod 11 drives the spherical block 12 to rotate and move. Since the spherical block 12 can be freely flipped in the spherical cylinder 16, the rotation and movement of the spherical block 12 pushes the spherical cylinder 16 and the extruder The pressure strip 15 moves, and the extrusion strip 15 moves toward the direction of the multiple cylindrical thin metal rods. The limiting slider 18 moves inside the limiting slide groove 17 on the extrusion strip 15, and the extension block 19 on the limiting slider 18 slides in the limiting groove 14 of the sliding groove 13. The extrusion strip 15 moves and pushes the multiple cylindrical thin metal rods to gather the multiple cylindrical thin metal rods together. At the same time, the outer cylindrical thin metal rods will rest against the inner wall of the fixing fixture 3 until the extrusion strip 15 rests against the cylindrical thin metal rods. After the multiple cylindrical thin metal rods are fixed together, the staff stops rotating the threaded moving rod 11 and places the fixed base plate 1 on the grinding machine. The staff grinds the tops of the multiple cylindrical thin metal rods. After grinding, the multiple cylindrical thin metal rods can be taken out.
