[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-2 An embodiment of this utility model provides: a composite mandrel adjustable groove grinding structure, including a support assembly 1, the support assembly 1 including a base 11, a support frame 12 and a base plate 13 fixedly connected to the upper surface of the base 11, an adjustment plate 15 slidably connected to the upper surface of the base plate 13 via a slide rail 14, a positioning bolt 17 threadedly connected to the horizontal end of the adjustment plate 15, and a positioning plate 16 fixedly connected to the upper surface of the base plate 13. By sliding the position of the adjustment plate 15, the distance between the adjustment plate 15 and the positioning plate 16 can be adjusted. At the same time, by pressing the positioning bolt 17 against the surface of the base plate 13, auxiliary positioning of the adjustment plate 15 can be achieved, ensuring the stability of its position.
[0022] See Figure 1 The top of the support frame 12 is provided with a grinding assembly 2, which is used for groove cutting of the composite mandrel. A clamping assembly 3 is provided on the side where the adjusting plate 15 and the positioning plate 16 are close to each other. The clamping assembly 3 is used for clamping and supporting the composite mandrel. It also includes a second motor 4 for rotating the clamping parts of a set of clamping assemblies 3, thereby driving the composite mandrel to rotate in a circle. By driving the clamping parts of the clamping assembly 3 to rotate through the second motor 4, the rotation of the composite mandrel can be realized, and then the grinding assembly 2 can be used to perform groove grinding on the outer wall of the composite mandrel.
[0023] Combination Figure 1 and Figure 4 Specifically, the grinding assembly 2 includes a housing 21, which is fixedly connected to the upper surface of the support frame 12. A first motor 22 is fixedly connected to the outer wall of the housing 21, and a lead screw 23 is connected to the output end of the first motor 22. A nut pair 24 is connected to the outside of the lead screw 23, and a guide seat 25 is fixedly connected to the outer wall of the nut pair 24. A mounting plate 26 is fixedly connected to the outer wall of the guide seat 25, and a cylinder 27 is fixedly connected to the other end of the mounting plate 26. A cutting tool 28 is connected to the lifting end of the cylinder 27. A guide groove is provided on the housing 21 to accommodate the left and right sliding of the guide seat 25. Plate 26 slides against the outer wall of housing 21. The centerline of tool 28 is on the same horizontal plane as the axis of second motor 4. The first motor 22 drives the lead screw 23 to rotate, thereby driving the guide seat 25 and mounting plate 26 to move laterally through the displacement of nut pair 24. This allows for the adjustment of the lateral displacement of cylinder 27 and tool 28, effectively adapting to different positions of composite mandrel for groove grinding. At the same time, the lifting start of cylinder 27 drives tool 28 to move back and forth, enabling tool 28 to effectively adapt to composite mandrels of different diameters for groove grinding.
[0024] Combination Figure 1 and Figure 3 Specifically, the clamping assembly 3 includes positioning sleeves 31. Each set of positioning sleeves 31 is fixedly connected to the side of the adjusting plate 15 and the positioning plate 16 that are close to each other. The positioning sleeve 31 is rotatably connected to a clamping shaft 34, and the clamping shaft 34 is the clamping component of the clamping assembly 3. The positioning sleeve 31 and the clamping shaft 34 are rotatably connected by ball bearings, so that after the two clamping shafts 34 clamp and position the composite mandrel, the second motor 4 can drive a set of clamping shafts 34 to rotate, thereby realizing the rotation of the composite mandrel.
[0025] The outer wall of the positioning sleeve 31 is integrally provided with a guide lug 32. A fastening bolt 33 is threaded inside the guide lug 32. An adjusting frame 35 is inserted inside the guide lug 32. The fastening bolt 33 abuts against the outer wall of the adjusting frame 35 to ensure its stability after adjustment. A support rod 36 is horizontally welded to the bottom outer wall of the adjusting frame 35. A support roller 37 is rotatably connected to the outside of the support rod 36. Two support rods 36 and support rollers 37 are symmetrically distributed on the outside of each adjusting frame 35. The support roller 37 is used for rolling support of the outer wall of the composite mandrel. The outer wall of the adjusting frame 35 is provided with... The support roller 37 has graduated lines, and the height of the support roller 37 can be adjusted by sliding the adjustment frame 35 up and down. This allows the support roller 37 to effectively adapt to composite mandrels of different diameters for rolling support, improving the stability of the composite mandrel clamping and positioning. At the same time, its rolling contact can reduce excessive compression of the clamping shaft 34, thus achieving stable rotation of the composite mandrel. In addition, the supporting rotational contact of the support roller 37 can provide good support force when the tool 28 performs grinding processing on the surface groove of the composite mandrel, thereby ensuring the stability of the composite mandrel rotation processing.
[0026] Working Principle: The first motor 22, cylinder 27, and second motor 4 used in this application are all commercially available products. Their principles and connection methods are well-known to those skilled in the art and will not be described in detail here. When using this utility model, the position of the adjusting plate 15 and the position of the support roller 37 are first adjusted according to the length and diameter of the composite mandrel. This allows the clamping shafts 34 at both ends to stably clamp the composite mandrel, while the support rollers 37 provide auxiliary support to the outer wall of the composite mandrel, ensuring the stability of the clamping shafts 34 in rotating the composite mandrel. The first motor 22 is then driven to rotate the lead screw 23. The lateral displacement of the nut pair 24 causes the guide seat 25 and the mounting plate 26 to move laterally. After the cylinder 27 and the cutter 28 move to the groove processing position on the outer wall of the composite mandrel, the second motor 4 drives the clamping shaft 34 to rotate, while the cylinder 27 drives the cutter 28 to move back and forth, thus realizing the groove grinding process on the outer wall of the composite mandrel.
[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
