[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1-5 As shown, a profiling polishing device includes a polishing mechanism 1 for processing a shaped part clamped and fixed by a clamping mechanism 2, which includes a grinding head sheet metal part 11 for pushing an abrasive belt 100 to fit the surface of the shaped part;

[0033] It also includes a guide post 31 installed on the base 3 and used to provide a guide for the grinding head sheet metal part 11 to slide. The guide post 31 is sleeved with a compression spring 32 that minimizes the distance between the abrasive belt 100 and the clamping mechanism 2 in a default state.

[0034] The swing rod 4 rotatably arranged on the base 3 is driven by the output end of the first motor 300 fixedly installed therein to negatively pressure the sanding belt 100, so that the distance between the grinding head sheet metal part 11 and the clamping mechanism 2 can be adjusted.

[0035] Specifically, it also includes a cabinet 7, and the polishing mechanism 1 includes a first guide rail slide 13 fixedly installed on the cabinet 7. The first screw rod 14 rotatably installed on the first guide rail slide 13 is fixedly connected to the output end of the third motor 71 fixedly installed on the cabinet 7, and the first screw rod 14 is used to drive the base 3 to slide in a direction parallel to the clamping mechanism 2. Secondly, the polishing mechanism 1 includes a second guide rail slide 15 slidably set on the first guide rail slide 13, and the second screw rod 16 rotatably installed on the second guide rail slide 15 is fixedly connected to the output end of the fourth motor 72 fixedly installed on the cabinet 7. The second screw rod 16 is threadedly connected to the base 3 slidably set on the second guide rail slide 15, and the second screw rod 16 is used to drive the base 3 to slide in a direction perpendicular to the clamping mechanism 2.

[0036] Further, combined with Figure 1 It can be seen that the cabinet 7 in the embodiment is fixedly mounted with an outer cover 8, and the special-shaped parts can be placed in and taken out after polishing through the hatch on the outer cover 8. Furthermore, the outer cover 8 in the embodiment is mounted with a control platform 9, and commands are output through the control platform 9 to control the operation of the equipment. The operation of the components between the above-mentioned mechanisms is coordinated by electronic components, such as infrared sensors, laser ranging sensors, and industrial cameras, etc. The specific control thereof belongs to the common technical knowledge of those skilled in the art, so it will not be described in detail.

[0037] Secondly, a plurality of positioning guide wheels 12 are rotatably arranged on the base 3 , and the plurality of positioning guide wheels 12 are rollingly connected to the abrasive belt 100 .

[0038] The grinding head sheet metal part 11 is slidably arranged on a guide rail part 33 fixedly installed on the base 3, and a roller is rotatably arranged on the end thereof.

[0039] A guide roller which is rotatably connected to the abrasive belt 100 is rotatably provided at the end of the swing rod 4 .

[0040] In the above technology, the base 3 can be driven by the linear module to slide in two directions parallel and perpendicular to the clamping mechanism 2, so as to move and grind the surface of the special-shaped part clamped by the clamping mechanism 2 as needed, and the sanding belt 100 is driven to shrink through the swing rod 4. Under the support of the grinding head sheet metal 11, the contact surface between the sanding belt 100 and the surface of the special-shaped part is adaptively changed according to the circumferential surface curvature of the surface of the special-shaped part, thereby realizing the grinding demand for rod-shaped special-shaped surfaces.

[0041] As an embodiment further provided by the present invention, an old grinding belt wheel 5 and a new grinding belt wheel 6 are rotatably arranged on the base 3, and the two ends of the grinding belt 100 are respectively wrapped around the old grinding belt wheel 5 and the new grinding belt wheel 6; and a pulley 200 is fixedly installed on the rotating shaft of the old grinding belt wheel 5 and the new grinding belt wheel 6, and the pulley 200 is connected to the output end of the second motor fixedly installed on the base 3 through a belt transmission. Secondly, a spring seat 201 arranged close to the pulley 200 is fixedly installed on the rotating shaft, and an equidistant spring 203 is arranged between the spring seat 201 and a rotating disk 202 rotatably arranged on the top inner side of the base 3.

[0042] Specifically, in the embodiment, during the polishing process, the second motor is used to drive the sanding belt 100 located at the end of the grinding head sheet metal 11 to change its surface, so as to always maintain the best grinding effect on the belt surface of the sanding belt 100 located at the end of the grinding head sheet metal 11.

[0043] As another embodiment further provided by the present invention, there are two groups of clamping mechanisms 2, which are respectively installed on a rotating platform 73 rotatably arranged on the cabinet 7, and the rotating platform 73 is fixedly connected to the output end of a rotating motor 74 fixedly installed in the cabinet 7.

[0044] Specifically, the clamping mechanism 2 in the embodiment has two groups, which are driven by the rotary motor 74 to rotate 90 degrees, thereby realizing the feeding of special-shaped parts and the removal of special-shaped parts after grinding.

The first push rods 21 of the two sets of clamping mechanisms 2 are symmetrically arranged along the diagonal line.

[0046] Specifically, when the special-shaped part is replaced in the embodiment, the slide table of the stepping linear motion module is driven to slide so that the second push rod 22 is away from the first push rod 21, and then the fourth motor is driven to keep the special-shaped part rotating at a uniform speed.

[0047] Working principle: The rotating motor 74 is driven to rotate 90° to realize the feeding of the special-shaped parts. The first screw rod 14 and the second screw rod 16 of the base 3 are driven to slide in two directions parallel and perpendicular to the clamping mechanism 2, so as to move and grind the surface of the special-shaped part clamped by the clamping mechanism 2 as needed. The sanding belt 100 is driven to shrink through the swing rod 4. Under the support of the grinding head sheet metal 11, the contact surface between the sanding belt 100 and the surface of the special-shaped part is adaptively changed according to the circumferential surface curvature of the surface of the special-shaped part.
