To further improve production efficiency and reduce equipment costs, many companies are choosing to integrate machining units into conveyor lines, performing intelligent processing directly on the conveyor line.

[0003] Among them, if the polishing processing unit is set on the conveyor line, it is necessary to ensure that the metal product to be processed can be automatically fixed when it is moved to the position of the polishing processing unit to ensure its stability during polishing.

[0004] In addition, the use and maintenance costs of traditional electric-driven polishing equipment are also high, and the metal dust generated during polishing can easily have adverse effects on the entire polishing equipment. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a metal product polishing device to solve the technical problems in the prior art of clamping and fixing the metal product during the polishing operation and the adverse effects of metal dust generated by polishing on the equipment.

[0024] Specific implementation and principle

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0026] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the usual meanings understood by people with ordinary skills in the field to which this utility model belongs. The "first", "second" and similar words used in this utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0027] The first aspect of the present invention is as follows Figure 1 As shown, the present invention integrates a polishing device into a conveyor line 101, improving production efficiency and reducing equipment costs. Specifically, a mounting base 102 is provided above the conveyor line 101 and is fixedly connected to the conveyor line 101 via a bracket 103. A telescopic cylinder 104 is fixedly mounted on the upper end of the mounting base 102. Below the mounting base 102 is an intermediate member 105 connected to the output shaft of the telescopic cylinder 104. Several grinding wheels 107 are rotatably connected to the lower end surface of the intermediate member 105 for polishing the metal product 01.

[0028] The polishing device is integrated into the conveyor line 101. When the metal product 01 to be processed is conveyed to the location of the polishing device, it can automatically fix the metal product 01 to be processed and polish it, which not only greatly improves the processing efficiency, but also does not affect the conveying operation of other positions of the conveyor line 101 itself.

[0029] In order to ensure that the metal product 01 to be processed can be automatically fixed when it is moved to the location of the polishing processing unit to ensure its stability during polishing, a hydraulic cylinder 111 is provided on both sides of the conveyor line 101 directly below the mounting seat 102. The hydraulic cylinder 111 is fixedly connected to the bracket 103, and the inner end of the output shaft of the hydraulic cylinder 111 passes through the side plate of the conveyor line 101. The inner end of the output shaft of the hydraulic cylinder 111 is also fixedly connected to a clamping plate 112. Figure 2 shown.

[0030] In addition, a laser sensor or other similar sensing device is set at an appropriate position near the splint 112, which can trigger a signal to the control system when the metal product 01 to be processed reaches the specified position. The control system then controls the operation of the hydraulic cylinder 111, the telescopic cylinder 104 and the solenoid valve in the air circuit.

[0031] Hydraulic cylinder 111 drives clamping plate 112 to clamp metal product 01, which not only responds quickly but also keeps metal product 01 stable during polishing. After polishing is completed, hydraulic cylinder 111 retracts and releases metal product 01, allowing conveyor line 101 to automatically transport metal product 01 to the next processing unit, streamlining the process and reducing costs.

[0032] On the other hand, Figure 3 and Figure 4 As shown, the polishing device of the present invention is driven by airflow. An air supply pipe 106 is fixedly connected to the mounting base 102, and the outer end of the air supply pipe 106 is connected to an external air pump. An air supply channel 108 is provided within the mounting base 102 and is connected to the inner end of the air supply pipe 106. In addition, a branch air flow channel 109 is provided within the intermediate member 105 and is connected to the air supply channel 108.

[0033] The upper end of the grinding wheel 107 is fixedly connected to the impeller 110 via a connecting rod, and the grinding wheel 107 is also rotatably connected to the lower end surface of the middle piece 105 via the connecting rod, wherein the impeller 110 is located in the branch flow channel 109 in the middle piece 105.

[0034] Therefore, the external air pump blows air through the air pipe 106 into the air channel 108, and then into the branch air channel 109 through the air channel 108, driving the impeller 110 to rotate, thereby driving the grinding wheel 107 to rotate for polishing operation, and the use and maintenance costs are relatively low.

[0035] Preferably, a plurality of air outlets connected to the branch air channels 109 are provided on the side wall of the intermediate member 105. Therefore, when the airflow is finally ejected through the air outlets, it can also blow away the metal dust generated during polishing, reducing the adverse effects of the metal dust on the entire polishing equipment.

[0036] On the other hand, since the telescopic cylinder 104 can drive the middle piece 105 to move up and down with the grinding wheel 107, the air connection between the mounting base 102 and the middle piece 105 also needs to be configured to be extendable and retractable.

[0037] like Figure 4 As shown, a thick tube connected to the gas delivery channel 108 is provided at the lower end of the mounting seat 102, and a thin tube connected to the branch flow channel 109 is provided at the upper end of the middle piece 105. The thin tube is slidably connected to the thick tube, and a sealing ring is provided between the two.

[0038] Therefore, when the telescopic cylinder 104 drives the middle piece 105 to rise and fall, the thin tube at the upper end of the middle piece 105 can also move up and down in the thick tube at the lower end of the mounting seat 102, and the lifting range of the middle piece 105 is limited, so the range of up and down movement of the thin tube in the thick tube is also limited, and it will not detach and cause gas leakage. DETAILED DESCRIPTION

[0039] When the metal product 01 to be processed is conveyed by rollers on the conveyor line 101 to the location of the polishing device, the laser sensor can trigger a signal to the control system. The control system controls the hydraulic cylinder 111 to work and drives the clamping plate 112 to clamp the metal product 01 to be processed. It responds quickly and can keep the metal product 01 stable while being polished.

[0040] At the same time, the control system activates telescopic cylinder 104 and opens the solenoid valve in the air circuit. Telescopic cylinder 104 lowers intermediate member 105, carrying grinding wheel 107, to begin polishing. As telescopic cylinder 104 raises and lowers intermediate member 105, the thin tube at the upper end of intermediate member 105 also moves up and down within the thick tube at the lower end of mounting base 102, maintaining a constant connection.

[0041] Therefore, the external air pump blows air through the air pipe 106 into the air delivery channel 108, and then enters the branch air channel 109 through the air delivery channel 108, driving the impeller 110 to rotate, thereby driving the grinding wheel 107 to rotate and perform the polishing operation.

[0042] During the polishing operation, the air flow is finally ejected through the air outlet, which can blow away the metal dust generated during polishing, reducing the adverse effects of the metal dust on the entire polishing equipment.

[0043] After the polishing process is completed, the telescopic cylinder 104 drives the middle piece 105 to rise, and then the hydraulic cylinder 111 contracts and releases the metal product 01. The conveyor line 101 can automatically transport the metal product 01 to the next processing unit, simplifying the process and saving costs.

[0044] Based on the above, the polishing device of the present invention is integrated into the conveyor line 101. When a metal product 01 is transported to the polishing device, it automatically secures and polishes it. This significantly improves processing efficiency while maintaining the conveying operation of the conveyor line 101. A hydraulic cylinder 111 drives a clamping plate 112 to clamp the metal product 01, ensuring rapid response and maintaining stability during polishing. After polishing is complete, the hydraulic cylinder 111 retracts and releases the metal product 01, allowing the conveyor line 101 to automatically transport it to the next processing unit, streamlining the process and reducing costs. The airflow drives the impeller 110, which in turn drives the grinding wheel 107 to perform the polishing operation, resulting in low operating and maintenance costs. Furthermore, the airflow, ejected through the air outlet, blows away metal dust generated during polishing, minimizing its adverse effects on the entire polishing equipment.
