Description

Technical Field

[0001] The utility model belongs to the field of grinding tools, in particular to a main roller repair welding and grinding tool based on a horizontal CNC ring rolling machine. Background Art

[0002] Ring rolling machine is one of the important equipment in the machinery manufacturing industry. It is used to produce annular mechanical parts of various shapes and sizes, such as bearing rings, gear rings, flanges, and wheel hubs. During the operation of the ring rolling machine, the main roller is subjected to huge rolling force and continuous high temperature operation, so the surface of the main roller is prone to wear. In order to ensure the surface quality of the blank, the worn parts of the main roller must be regularly repaired and filled. However, the surface of the main roller after repair welding is often uneven due to the uneven thickness of the repair welding, which not only affects the subsequent rolling operation, but also may cause potential risks to product quality. Therefore, grinding the repair welding parts is an essential process step.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 As shown, a main roller repair welding and grinding tool based on a horizontal CNC ring rolling machine includes a clamping tool 3 and a grinding mechanism 6. The clamping tool 3 is installed on the core roller 1. Figure 4 As shown, the clamping tool 3 includes a fixed seat 31, and both ends of the fixed seat 31 are fixedly connected to a fixed rod 32, one end of the fixed rod 32 is detachably connected to an end cover 33, the middle part of the end cover 33 is threadedly connected to a screw rod 34, one end of the screw rod 34 is fixedly connected to a handle, and the other end of the screw rod 34 is movably connected to a clamping seat 35, the fixed seat 31 and the clamping seat 35 are respectively clamped on the core roller 1, and the grinding tool is installed on the core roller 1, which ensures the stability of the grinding tool; Figure 2 As shown, the grinding mechanism 6 includes a motor base 62 and a grinding motor 61 installed on one side of the motor base 62. One side of the motor base 62 is connected to the clamping fixture 3. A grinding plate 63 is connected to the output shaft of the grinding motor 61. The grinding motor 61 drives the grinding plate 63 to rotate to grind the repaired welding part of the main roller 2, which not only reduces the labor intensity of the operators, but also improves the efficiency of the grinding of the main roller 2, and ensures the stability and consistency of the grinding of the main roller 2 after the repair welding.

[0029] like Figure 4 As shown, arc-shaped guide grooves 36 are provided on both sides of the clamp seat 35 , and the arc-shaped guide grooves 36 on both sides of the clamp seat 35 cooperate with the fixing rod 32 to limit the rotation of the clamp seat 35 and avoid the clamp seat 35 from rotating when the clamping tool 3 is clamped.

[0030] Furthermore, the rotation direction of the polishing sheet 63 is opposite to that of the main roller 2 , wherein the power for the rotation of the main roller 2 comes from the power of the ring rolling machine itself, and its structure is not described in detail, thereby ensuring the efficiency of the grinding of the main roller 2 .

[0031] like Figure 2 As shown, the clamping fixture 3 is provided with two groups, and the two groups of clamping fixtures 3 are both installed on the core roller 1. One side of the fixed seat 31 of the two groups of clamping fixtures 3 is provided with a limiting end plate 37, and a height adjustment mechanism 5 is provided between the two limiting end plates 37. The height adjustment mechanism 5 includes a guide rod 52 and a driving mechanism arranged on one side of the guide rod 52. Both ends of the guide rod 52 are connected to the limiting end plate 37. One side of the height adjustment mechanism 5 is provided with a connecting component 4, as shown in FIG. Figure 3 As shown, the connecting assembly 4 includes a first connecting plate 41, and the motor seat 62 is connected to the first connecting plate 41. The first connecting plate 41 is fixedly connected to the second connecting plate 42 on one side, and the second connecting plate 42 is provided with a guide sleeve 44 at one end, and the guide sleeve 44 is loosely sleeved on the outside of the guide rod 52; the height adjustment mechanism 5 is convenient for adjusting the height of the grinding mechanism 6, so that the main roller 2 at different positions can be ground by clamping once, and the efficiency of grinding the main roller 2 is further improved.

[0032] Furthermore, the driving mechanism includes but is not limited to an electric push rod, a hydraulic cylinder, a pneumatic cylinder and a lead screw 51. In this embodiment, Figure 2 As shown, the driving mechanism adopts a lead screw 51, both ends of which are rotatably connected to the limit end plate 37, a screw sleeve 43 is provided on the second connecting plate 42, the lead screw 51 is threadedly connected to the screw sleeve 43, and the upper end of the lead screw 51 is fixedly connected to a power mechanism, which is manual or electric. In the present embodiment, the power mechanism adopts a hand wheel 53; by rotating the hand wheel 53, the connecting assembly 4 is driven to move on the guide rod 52, thereby realizing the adjustment of the position of the grinding mechanism 6.

[0033] like Figure 5 , Figure 6 As shown, it also includes a polishing mechanism 7, the polishing mechanism 7 includes a polishing frame 71. After the main roller 2 is roughly ground, the grinding mechanism 6 is removed and the polishing frame 71 is connected to the connecting assembly 4. One end of the polishing frame 71 is rotatably connected to a driving wheel 72. A polishing motor 75 is provided on the upper part of the polishing frame 71. The polishing motor 75 is connected to the driving wheel 72. The other end of the polishing frame 71 is symmetrically connected to two driven wheels 73. The driven wheel 73 is movably connected to a wheel frame 76 on the outside. A connecting rod 77 is provided on one side of the wheel frame 76. The connecting rod 77 is connected to the polishing frame 71. The driving wheel 72 is connected to the two driven wheels 73 through a polishing belt 74. The polishing mechanism 7 polishes and fine-grinds the main roller 2 after rough grinding to ensure the roughness requirement of the main roller 2.

[0034] like Figure 6As shown, one side of the polishing frame 71 is fixedly connected to two sleeves 78, and the connecting rod 77 is intermittently inserted inside the sleeve 78. One end of the connecting rod 77 is fixedly connected to a spring 79, and the other end of the spring 79 is fixedly connected to the end of the sleeve 78. When the core roller 1 drives the grinding tooling to move toward the side of the main roller 2, after the polishing belt 74 contacts the main roller 2, the core roller 1 continues to move a distance toward the side of the main roller 2, so that the polishing belt 74 is bent. At this time, the driven wheel 73 shrinks toward the side of the polishing frame 71, and the spring 79 is compressed. The polishing belt 74 is automatically tensioned under the action of the spring 79, and the bent polishing belt 74 increases the contact area between the polishing belt 74 and the main roller 2, thereby improving the polishing efficiency of the polishing mechanism 7.
