[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figures 1-5 This utility model relates to a device for preventing damage to the center hole of a steering gear shaft component. It includes a machine base 1, a fixed sleeve 2, a supporting angle iron 3, and a shaft 4. A connecting shaft 101 is fixed to the output end of the machine base 1. When the machine base 1 is working, it generates power to drive the connecting shaft 101 to rotate. The machine base 1 is connected to a center point 102 via the connecting shaft 101. The fixed sleeve 2 is sleeved around the periphery of the connecting shaft 101. When the fixed sleeve 2 is working, a connecting frame 201 is connected to it. The connecting frame 201 is fixed to the end of the fixed sleeve 2 away from the machine base 1. When the connecting frame 201 is working, the supporting angle iron 3 is supported and mounted on it. A [missing information - likely a device or structure] is provided above the connecting frame 201. The support angle iron 3 supports the shaft 4 being machined during operation. The bottom of the support angle iron 3 is fixed with connecting block 1 301 and connecting block 2 302 along the corner edge. The support angle iron 3 is connected to the insert rod 303 through connecting block 1 301 and to the threaded rod 304 through connecting block 2 302. The bottom end of connecting block 1 301 is rotatably connected to the threaded rod 304. When the threaded rod 304 rotates, it is threadedly connected to the connecting frame 201, which drives the support angle iron 3 to rise and fall. The shaft 4 is movably installed inside the support angle iron 3. After the shaft 4 is abutted by the center 102, it can be clamped on the machine tool being machined with calipers or the like.

[0026] Specifically, a fixing plate 103 is fixed on the periphery of the connecting shaft 101. The fixing plate 103 abuts against the fixing sleeve 2, and the fixing plate 103 is located between the fixing sleeve 2 and the machine base 1. The connecting shaft 101 restricts the position of the fixing sleeve 2 on it through the fixing plate 103.

[0027] Furthermore, a center 102 is fixed at the end of the connecting shaft 101 away from the machine tool 1. The center 102 abuts against the end of the shaft 4. When the machine tool 1 moves to the point where the center 102 abuts against the center of the end of the shaft 4 and is tightened, the shaft 4 can be clamped and supported on the machine tool in conjunction with the three-jaw caliper.

[0028] Furthermore, the connecting frame 201 is arranged in a Z-shape, and the angles at both corners of the connecting frame 201 are obtuse angles. A reinforcing plate 204 is fixed on the inner side of the higher corner of the connecting frame 201. When the connecting frame 201 is working, its support strength is increased by the reinforcing plate 204.

[0029] The operation process of this embodiment is as follows: During operation, firstly, a shaft 4 is clamped by a three-jaw caliper on the machine tool, then the fixing sleeve 2 is put on the side of the connecting shaft 101 on the machine tool 1, and the position is restricted by the fixing plate 103. Then, the rotating frame 305 is rotated to drive the support angle iron 3 to rise until the support angle iron 3 supports the shaft 4. Then, the lathe drive mechanism of the machine tool 1 is started to adjust the machine tool 1 to the end of the shaft 4. At this time, the rotating frame 305 is rotated again to adjust the position of the end of the shaft 4 until the end of the shaft 4 is aligned with the end of the tip 102 to prevent damage to the center hole of the end of the shaft 4 when the tip 102 abuts against the end of the shaft 4. Specific Implementation Example 2

[0030] Please see Figures 1-5 Based on the first specific embodiment, the connecting frame 201 has a lower horizontal part with an insertion hole 202 and a threaded hole 203 respectively opened along the central axis. The insertion hole 202 is located near the corner of the connecting frame 201, and the threaded hole 203 is located away from the corner of the connecting frame 201. The connecting frame 201 is movably connected to the insertion rod 303 through the insertion hole 202, and the threaded rod 304 is threadedly connected through the threaded hole 203.

[0031] Specifically, a rod 303 is fixed to the bottom of the connecting block 2 302. The rod 303 is inserted into the insertion hole 202. The threaded rod 304 is threaded into the threaded hole 203. A rotating bracket 305 is fixed to the bottom of the threaded rod 304. When the connecting block 2 302 is working, the rod 303 is inserted into the insertion hole 202 to limit the position of the insertion hole 202. By rotating the rotating bracket 305, the threaded rod 304 is rotated to adjust the height of the supporting angle iron 3.

[0032] The operation process of this embodiment is as follows: When working, after the shaft 4 is pressed against the center 102, the rotating frame 305 can be rotated to drive the threaded rod 304 to rotate, causing the support angle iron 3 to descend. This activates the rotating structure corresponding to the three-jaw caliper, driving the shaft 4 to rotate. Through the rotation of the shaft 4, the shaft 4 is machined with the cooperation of the cutting tool. After the shaft 4 is machined, the fixing sleeve 2 is rotated to adjust the connecting frame 201 to be positioned below the shaft 4. Then, the rotating frame 305 is rotated to drive the threaded rod 304 to rotate, causing the support angle iron 3 to rise until the support angle iron 3 rises to support the shaft 4. Then, the machine base 1 can be driven away from the end of the shaft 4. Since the shaft 4 is well supported, the tip of the center 102 remains stable when leaving the center hole of the shaft 4, and will not scratch the edge of the center hole.
