[0008] Furthermore, the support assembly also includes a bending transition section arranged between the first adjustment rod and the disc base, and the bending transition section is located on the inner side of the U-shaped frame and extends in an L-shaped bend in a direction away from the horizontal frame.

[0009] Furthermore, in the relative directions of the two longitudinal frames, the length of the first adjusting rod located on the inner side of the U-shaped frame is adjustable, the outer periphery of the first adjusting rod has an external thread, and the support assembly also includes a first nut. The first adjusting rod is threadedly connected to a first nut on the outer periphery on both sides of the inner and outer sides of the longitudinal frame. The two first nuts are respectively detachably abutted against the inner and outer sides of the longitudinal frame to limit or loosen the position of the first adjusting rod in the strip slide groove.

[0010] Furthermore, the mounting frame is a clamp frame with an opening, and the opening of the clamp frame is detachably connected by a sealing bolt assembly.

[0011] Furthermore, a reinforcing block is provided in the middle area of ​​the cross frame, and at least one end of the reinforcing block in the transverse width direction protrudes from the cross frame. The mounting assembly also includes an adjusting assembly for adjusting the position of the mounting frame, and the adjusting assembly is provided on the area where the reinforcing block protrudes from the cross frame, so that the area of ​​the mounting frame used to mount the product to be polished is staggered with the cross frame in the width direction of the cross frame.

[0012] Furthermore, the adjustment assembly includes a second nut and a second adjustment rod with an external thread. The second adjustment rod passes through the reinforcement block in a direction perpendicular to the horizontal frame. The mounting frame is arranged on the side where the second adjustment rod passes through the inner side of the U-shaped frame. The second adjustment rod is located on the outer periphery of the inner and outer sides of the reinforcement block and is threadedly connected with a second nut. The two second nuts are respectively detachably abutted against the inner and outer sides of the reinforcement block to limit the length of the second adjustment rod passing through the U-shaped frame.

[0013] Furthermore, a sleeve for passing the second adjusting rod is provided on the outer periphery of the mounting frame, and a stopper is provided at the end of the second adjusting rod extending into the inner side of the U-shaped frame, and the stopper cooperates with the sleeve stopper.

[0014] Furthermore, there are two reinforcement blocks, and the mounting frame is connected to the two reinforcement blocks respectively through two groups of adjustment components.

[0015] The technical solution of the present invention is applied to provide an auxiliary bracket for a grinder, including a U-shaped frame, a mounting assembly and a support assembly. The U-shaped frame includes a horizontal frame and two vertical frames respectively arranged at both ends of the horizontal frame. When the U-shaped frame is installed on the product to be polished, the horizontal frame is flush with the surface to be polished of the product to be polished, and the two vertical frames are respectively located on both sides of the product to be polished. The mounting assembly is arranged on the horizontal frame and includes a mounting frame for transferring the grinder. The position of the mounting frame in a direction perpendicular to the horizontal frame is adjustable to adjust the relative position of the polishing end of the grinder and the horizontal frame and the surface to be polished. At least one support assembly is provided on any one of the vertical frames. The position of the support assembly in the extension direction of the vertical frame is adjustable and has a support end located between the two vertical frames. The support ends of multiple support assemblies are detachably abutted against the bottom of the product to be polished.

[0016] The products to be polished in this scheme are mainly square steel bars. When the products to be polished need to be polished, the polishing machine is first installed on the mounting frame of the mounting assembly, and then the U-shaped frame is turned upside down on the product to be polished (the inner side of the horizontal frame is facing the surface to be polished, and the two vertical frames are located on both sides of the product to be polished) and the position of the supporting assembly under the product to be polished is adaptively adjusted so that the supporting assembly supports the bottom of the product to be polished, and then the U-shaped frame is clamped on the product to be polished to complete the installation of the U-shaped frame. After that, the position of the mounting frame is adaptively adjusted to adjust the height of the polisher, so that the polisher can effectively contact the surface to be polished of the product to be polished, thereby ensuring the polishing effect of the polisher on the surface to be polished. With this arrangement, due to the limited installation of the U-shaped frame and the workpiece to be polished, the U-shaped frame and the polishing machine installed thereon will not slip or deflect, which will affect the polishing effect and operational safety. The operator only needs to slide the U-shaped frame when polishing different positions of the surface to be polished. Combined with the adjustment of the position of the mounting frame, this is conducive to ensuring the polishing effect of the surface to be polished while improving the reliability and stability of the polishing.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way serves as any limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 3 As shown, an embodiment of the present invention provides a grinder auxiliary bracket, including a U-shaped frame 1, a mounting assembly 2 and a support assembly 3. The U-shaped frame 1 includes a horizontal frame 12 and two vertical frames 13 respectively arranged at both ends of the horizontal frame 12. When the U-shaped frame 1 is installed on the product to be polished, the horizontal frame 12 is flush with the surface to be polished of the product to be polished, and the two vertical frames 13 are respectively located on both sides of the product to be polished. The mounting assembly 2 is arranged on the horizontal frame 12 and includes a mounting frame 22 for transferring the grinder. The position of the mounting frame 22 in a direction perpendicular to the horizontal frame 12 is adjustable to adjust the relative position of the polishing end of the grinder and the horizontal frame 12 and the surface to be polished. At least one support assembly 3 is provided on any one of the vertical frames 13. The position of the support assembly 3 in the extension direction of the vertical frame 13 is adjustable and has a support end located between the two vertical frames 13. The support ends of multiple support assemblies 3 are detachably abutted against the bottom of the product to be polished.

[0027] The product to be polished in this embodiment is mainly a bar-shaped square steel. When the product to be polished needs to be polished, the polishing machine is first installed on the mounting frame 22 of the mounting assembly, and then the U-shaped frame 1 is turned upside down on the product to be polished (the inner side of the horizontal frame 12 is facing the plane to be polished, and the two vertical frames 13 are respectively located on both sides of the product to be polished) and the position of the supporting assembly 3 located below the product to be polished is adaptively adjusted so that the supporting assembly 3 supports the bottom of the product to be polished, and then the U-shaped frame 1 is clamped on the product to be polished to complete the installation of the U-shaped frame 1. After that, the position of the mounting frame 22 is adaptively adjusted to adjust the height of the polisher, so that the polisher can effectively contact the surface to be polished of the product to be polished, thereby ensuring the polishing effect of the polisher on the surface to be polished. With this arrangement, due to the limited installation of the U-shaped frame 1 and the product to be polished, the U-shaped frame 1 and the polishing machine installed thereon will not slip or deflect, which will affect the polishing effect and operational safety. The operator only needs to slide the U-shaped frame 1 when polishing different positions of the surface to be polished. Combined with the adjustment of the position of the mounting frame 22, it is beneficial to improve the reliability and stability of the polishing while ensuring the polishing effect of the surface to be polished.

[0028] like Figure 1 and Figure 2 As shown, a support assembly 3 is provided on any one of the longitudinal frames 13. The longitudinal frame 13 has a strip chute 11 on the side facing away from the transverse frame 12. The support assembly 3 includes a first adjusting rod 36. The first adjusting rod 36 is provided perpendicular to the longitudinal frame 13 and passes through the strip chute 11. The position of the first adjusting rod 36 in the strip chute 11 is adjustable to adjust the support position of the support end on the inner side of the U-shaped frame 1 in the extension direction of the longitudinal frame 13 for the bottom of the product to be polished. The length of the first adjusting rod 36 extending into the inner side of the U-shaped frame 1 is adjustable to adjust the support position of the support end on the inner side of the U-shaped frame 1 in the extension direction of the transverse frame 12 for the bottom of the product to be polished.

[0029] This arrangement allows the first adjustment rod 36 and the support end to be guided in the direction of extension of the longitudinal frame 13 via the strip-shaped chute 11, ensuring reliable installation and adjustment of the first adjustment rod 36. Furthermore, by adjusting the length of the first adjustment rod 36 extending into the inner side of the U-shaped frame 1, the position of the support end in the direction of extension of the transverse frame 12 can be adjusted, thereby increasing the adjustable range of the support end, enabling support for the bottoms of square steel bars of varying widths and thicknesses, and improving the applicability of the auxiliary support for the polishing machine.

[0030] Specifically, the support assembly 3 also includes a disc base 32, a hinge seat 33 and a ball 34. The disc base 32 is located on the inner side of the U-shaped frame 1 and its surface is parallel to the cross frame 12. The hinge seat 33 is arranged on the side of the disc base 32 facing the cross frame 12. The ball 34 is at least partially rotatably embedded in the hinge seat 33 and forms a support end that can be detachably abutted against the bottom of the product to be polished.

[0031] With this arrangement, rolling support is provided for the bottom of the product to be polished (bar-shaped square steel) through the ball bearings 34, making it easier for the U-shaped frame 1 to slide on the product to be polished (bar-shaped square steel), avoiding excessive friction between the support assembly 3 and the bottom of the product to be polished (bar-shaped square steel) resulting in inconvenient sliding or easy damage to both, and improving the convenience of the grinder in sliding and polishing along the product to be polished (bar-shaped square steel).

[0032] Furthermore, the support assembly 3 further includes a bending transition section 31 provided between the first adjustment rod 36 and the disc base 32 . The bending transition section 31 is located on the inner side of the U-shaped frame 1 and extends in an L-shaped bend in a direction away from the horizontal frame 12 .

[0033] With this arrangement, the disc base 32 can be further away from the cross frame 12 by bending the transition section 31, which is beneficial to increasing the thickness range of the products to be polished (bar-shaped square steel) that can be supported by the support assembly 3 and further improving the applicability of the auxiliary bracket of the polishing machine.

[0034] It is understood that, depending on the different products to be polished, the disc base 32 can selectively directly support the bottom of the product to be polished, or extend into the bottom area of ​​the product to be polished and support its bottom.

[0035] In this embodiment, in the relative directions of the two longitudinal frames 13, the length of the first adjusting rod 36 located on the inner side of the U-shaped frame 1 is adjustable, the outer periphery of the first adjusting rod 36 has an external thread, and the support assembly 3 also includes a first nut 35. The first adjusting rod 36 is threadedly connected to a first nut 35 on the outer periphery of the inner and outer sides of the longitudinal frame 13. The two first nuts 35 are detachably abutted against the inner and outer sides of the longitudinal frame 13 respectively to limit or relax the position of the first adjusting rod 36 in the strip slide groove 11.

[0036] With this arrangement, when it is necessary to adjust the position of the support end, for any support component 3, loosen at least one first nut 35 so that the position of the first adjustment rod 36 in the strip slide 11 is adjustable, and then adjust the length of the first adjustment rod 36 extending into the inner side of the U-shaped frame 1 and the position of the first adjustment rod 36 in the strip slide 11 and adaptively adjust the positions of the two first nuts 35 as the first adjustment rod 36 moves. After the adjustment is completed, tighten the two first nuts 35 at the same time so that the two first nuts 35 are clamped on the inner and outer sides of the longitudinal frame 13, thereby achieving the limitation of the position of the first adjustment rod 36.

[0037] It is understandable that during the adjustment process, it is preferred to keep the disc base 32 parallel to the cross frame 12 or the bottom of the product to be polished (bar-shaped square steel) to ensure the supporting effect.

[0038] like Figures 1 to 3As shown, the mounting frame 22 is a clamp frame with an opening, and the opening of the clamp frame is detachably connected by a sealing bolt assembly 24. This arrangement is conducive to improving the applicability of the mounting frame 22 to grinders of different sizes.

[0039] like Figure 1 and Figure 2 As shown, a reinforcement block 14 is provided in the middle region of the horizontal frame 12, with at least one end of the reinforcement block 14 protruding from the horizontal frame 12 in the transverse width direction. The mounting assembly 2 also includes an adjustment assembly for adjusting the position of the mounting bracket 22. The adjustment assembly is provided in the region where the reinforcement block 14 protrudes from the horizontal frame 12, so that the region of the mounting bracket 22 for mounting the product to be polished is offset from the horizontal frame 12 in the width direction of the horizontal frame 12. This arrangement prevents the horizontal frame 12 from interfering with the installation of the polishing machine, thereby ensuring reliable and convenient installation of the polishing machine.

[0040] Specifically, the adjustment assembly includes a second nut 26 and a second adjustment rod 21 with an external thread. In a direction perpendicular to the cross frame 12, the second adjustment rod 21 passes through the reinforcement block 14. The mounting frame 22 is arranged on the side where the second adjustment rod 21 penetrates the inner side of the U-shaped frame 1. The outer periphery of the second adjustment rod 21 on both the inner and outer sides of the reinforcement block 14 is threadedly connected with a second nut 26. The two second nuts 26 are respectively detachably abutted against the inner and outer sides of the reinforcement block 14 to limit the length of the second adjustment rod 21 penetrating into the U-shaped frame 1.

[0041] In this embodiment, the mounting bracket 22 is slidably set on the second adjusting rod 21. When the position of the mounting bracket 22 needs to be adjusted, at least one second nut 26 is loosened to allow the second adjusting rod 21 to move. Then, the length of the second adjusting rod 21 extending into the inner side of the U-shaped frame 1 is adjusted and the positions of the two second nuts 26 are adaptively adjusted as the second adjusting rod 21 moves. The length of the second adjusting rod 21 extending into the inner side of the U-shaped frame 1 is the maximum adjustable length of the mounting bracket 22 in the U-shaped frame. After the maximum adjustable length adjustment is completed, the two second nuts 26 are tightened at the same time so that the two are respectively pressed against the inner and outer sides of the reinforcement block 14, thereby realizing the limitation of the position of the second adjusting rod 21. The operator can manually adjust the mounting bracket 22 to a certain position within the maximum adjustable length according to actual needs.

[0042] Furthermore, the outer periphery of the mounting bracket 22 is provided with a sleeve 23 for passing the second adjustment rod 21. The end of the second adjustment rod 21 extending into the inner side of the U-shaped frame 1 is provided with a stopper 25, which engages with the sleeve 23. This arrangement facilitates the connection between the mounting bracket 22 and the second adjustment rod 21 through the sleeve 23, while the stopper 25 prevents the mounting bracket 22 from being dislodged from the second adjustment rod 21.

[0043] In this embodiment, two reinforcement blocks 14 are provided, and the mounting frame 22 is connected to the two reinforcement blocks 14 via two sets of adjustment assemblies, respectively. This arrangement improves the reliability and stability of the support and adjustment of the mounting frame 22. It will be appreciated that the two sets of adjustment assemblies operate synchronously to adjust the position of the mounting frame 22.

[0044] In summary, the present invention provides an auxiliary bracket for a polishing machine. When in use, the polishing machine is first installed on the mounting frame 22 of the mounting assembly, and then the U-shaped frame 1 is turned upside down on the product to be polished (the inner side of the horizontal frame 12 is facing the surface to be polished, and the two vertical frames 13 are respectively located on both sides of the product to be polished). The position of the first adjusting rods 36 on both sides in the strip slide 11 and the length of the first adjusting rods 36 extending into the inner side of the U-shaped frame 1 are adjusted. After the adjustment is completed, the first adjusting rods 36 are fixed by the first nut 35 to achieve the support of the bottom of the support assembly 3 to be polished. Then, according to the required maximum adjustment length range for the movable mounting frame 22, the length of the two second adjusting rods 21 extending into the inner side of the U-shaped frame 1 is adaptively adjusted. After the adjustment is completed, the second adjusting rod 21 is fixed by the second nut 26, so that the operator can adjust the position of the mounting frame 22 and enable the polishing machine to effectively contact the surface to be polished of the product to be polished, thereby ensuring the polishing effect of the polishing machine on the surface to be polished. With this arrangement, due to the limited installation of the U-shaped frame 1 and the product to be polished, the U-shaped frame 1 and the polishing machine installed thereon will not slip or deflect, which will affect the polishing effect and operational safety. The operator only needs to slide the U-shaped frame 1 when polishing different positions of the surface to be polished. Combined with the adjustment of the position of the mounting frame 22, it is beneficial to improve the reliability and stability of the polishing while ensuring the polishing effect of the surface to be polished.
