Description

Technical Field

[0001] The invention belongs to the technical field of polishing equipment, and in particular relates to an automatic pipeline polishing equipment. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and flat surface. It uses polishing tools and abrasive particles or other polishing media to modify the surface of a workpiece. Usually, a polishing wheel is used as a polishing tool. During polishing, the high-speed rotating polishing wheel presses against the workpiece, causing the abrasive to roll and slightly cut the surface of the workpiece, thereby obtaining a bright processed surface.

[0003] When polishing a pipe, it is sometimes necessary to polish the outer surface and the inner surface of the pipe separately. At present, the inner surface polishing and the outer surface polishing of the pipe are mostly divided into two processes and performed separately. The two polishings are time-consuming, resulting in low polishing efficiency.

[0004] In addition, for workpieces with high polishing accuracy requirements, surface inspection is required after polishing. Since inner surface polishing and outer surface polishing are two processes located in different workstations, it is not convenient to rework unqualified workpieces in a timely manner.

[0005] Therefore, it is urgent to propose an automatic polishing equipment that integrates inner surface polishing, outer surface polishing and surface inspection to reduce manual participation and improve polishing efficiency. Summary of the invention

DETAILED DESCRIPTION

[0028] Embodiment 1

[0029] like Figure 1 As shown, an automatic pipeline polishing equipment includes a polishing station 2 and an inspection station 3. A polishing mechanism 4 for polishing the outer surface of a workpiece and a polishing mechanism 5 for polishing the inner surface of the workpiece are arranged on the side of the polishing station 2; an inspection mechanism 6 is arranged on the side of the inspection station 3, and the inspection mechanism 6 includes an inspection camera 601 for inspecting the surface of the workpiece. A material transfer mechanism 1 is set above the polishing station 2 and the inspection station 3, and the material transfer mechanism 1 is used to clamp and transfer the workpiece to realize loading or unloading operations of the workpiece.

[0030] Specifically, the material moving mechanism 1 includes a material moving component 12 and a material moving component 2 13 that reciprocate on the moving track 101. The material moving component 12 is used to load the material to the polishing station 2 and transfer the polished workpiece to the inspection station 3. The principle of sliding displacement between the moving component 12, the moving component 2 13 and the moving track 101 is the same as that of the moving module.

[0031] When the workpiece on the inspection station 3 passes the inspection, the material transfer component 2 13 transfers the workpiece to the next process; when the workpiece on the inspection station 3 fails the inspection, the material transfer component 2 13 clamps the workpiece and then shifts, waiting for the material transfer component 12 to transfer another workpiece that has been polished on the polishing station 2 to the inspection station 3, and then the material transfer component 2 13 transfers the unqualified workpiece to the polishing station 2 for secondary polishing.

[0032] For example: the material transfer component 12 clamps and transfers the workpiece 1 to the polishing station 2 for polishing operation. After the polishing is completed, the material transfer component 2 13 clamps and transfers the workpiece 1 to the inspection station 3. At the same time, the material transfer component 12 clamps and transfers the workpiece 2 to the polishing station 2 for polishing operation. At this time, the workpiece 2 is placed in the polishing station 2, and the workpiece 1 is placed in the inspection station 3. While the workpiece 2 is being polished, the surface of the workpiece 1 is inspected.

[0033] When the surface inspection of workpiece 1 is qualified, material transfer component 2 13 clamps workpiece 1 and transfers it to the next process. At the same time, material transfer component 12 clamps workpiece 2 and transfers it to inspection station 3, then returns to the initial position and clamps workpiece 3 and transfers it to polishing station 2.

[0034] When the surface inspection of workpiece 1 fails, the material transfer component 2 13 clamps and shifts workpiece 1. At the same time, the material transfer component 12 clamps and transfers workpiece 2 to the inspection station 3 and then returns to the initial position to wait. At this time, the material transfer component 2 13 clamps and transfers workpiece 1 to the polishing station 2 for secondary polishing. At this time, workpiece 1 is placed in the polishing station 2, and workpiece 2 is placed in the inspection station 3. While workpiece 1 is undergoing secondary polishing, workpiece 2 undergoes surface inspection.

[0035] Through the mutual cooperation between the mobile component 1 12 and the mobile component 2 13, the loading or unloading of the polishing station 2 and the testing station 3 is realized, so that the polishing station 2 and the testing station 3 can work in coordination.

[0036] Furthermore, the polishing mechanism 1 4 and the polishing mechanism 2 5 perform secondary polishing on the unqualified positions of the workpiece according to the detection results of the detection mechanism 6 .

[0037] like Figure 2 As shown, the polishing station 2 and the inspection station 3 both include a moving assembly 9, which is used to drive the workpiece to rotate and drive the workpiece to reciprocate on the fixed plate 7. The two moving assemblies 9 are driven by a motor four 10 and move synchronously on the fixed plate 7 at corresponding positions, so that the polishing mechanism one 4 and the polishing mechanism two 5 pass through the head end and the tail end of the workpiece.

[0038] like Figure 2 , Figure 3As shown, the moving assembly 9 includes a slide 901 and a rolling wheel 905, wherein two rolling wheels 905 are arranged opposite to each other, and the two rolling wheels 905 are driven by the motor 3 903 and the transmission assembly 1 904 to rotate on the top of the slide 901, and the workpiece is located between the two rolling wheels 905, and the workpiece is driven to rotate by the rotating rolling wheels 905. Specifically, one end of the rolling wheel 905 is rotatably connected to the slide 901 through a bearing 906, and the other end is rotatably connected to the slide 901 through the transmission assembly 1 904, wherein the transmission assembly 1 904 includes a gear and a rack, and the rolling wheel 905 is connected to the driving end of the motor 3 903 through the gear and the rack, so that the motor 3 903 drives the rolling wheel 905 to rotate.

[0039] In addition, if Figure 2 As shown, the polishing station 2 and the inspection station 3 are each provided with two relatively distributed fixed plates 7, and both ends of the fixed plates 7 are respectively connected with limit bolts 8 for limiting the position of the moving component 9 moving left and right.

[0040] like Figure 3 , Figure 5 As shown, the moving component 9 includes a slide plate 902, and the two ends of the bottom of the slide plate 902 are respectively connected to cross bars 909 through connecting seats 9011, and the two ends of the cross bar 909 are respectively connected to clamping wheels 9012 overlapped with the fixed plate 7. The two cross bars 909 are driven by motor four 10, gear box 907, transmission component two 908, and transmission component three 9010 to rotate synchronously, thereby driving the clamping wheel 9012 to roll on the fixed plate 7 and driving the slide plate 902 to move.

[0041] Specifically, the output shaft of motor four 10 is connected to a rotating shaft of the gear box 907, and the other rotating shaft of the gear box 907 is connected to one of the two cross bars 909 through transmission component two 908, and the two cross bars 909 are connected through transmission component three 9010.

[0042] The motor 4 10 drives the transmission assembly 2 908 through the gear box 907, thereby driving the crossbar 909 connected to the transmission assembly 2 908 to rotate, and then drives another crossbar 909 to rotate through the transmission assembly 3 9010, and the rotation of the crossbar 909 causes the clamping wheel 9012 to roll on the fixed plate 7, thereby driving the slide plate 902 to move, so that the workpiece can move left and right. Among them, the transmission assembly 2 908 and the transmission assembly 3 9010 include gears and racks, and the motor 4 10 can drive the slide plate 902 to move through the gears and racks.

[0043] like Figure 6As shown, the gear boxes 907 in the two moving components 9 are connected to the motor four 10 through the synchronous belt 11, so that the motor four 10 can drive the two moving components 9 to move synchronously, so that the two moving components 9 always maintain a relative position, which is convenient for the material moving component 12 and the material moving component 13 to realize the loading or unloading of the polishing station 2 and the inspection station 3.

[0044] In addition, if Figure 2 As shown, the polishing mechanism 4 includes a polishing wheel 404 driven to rotate by a motor 402. The polishing wheel 404 is mounted above the workpiece through an adjusting rod 403 and a supporting column 401. The angle between the adjusting rod 403 and the supporting column 401 is adjustable. The polishing wheel 404 moves with the moving component 9 and passes through the head end and the tail end of the workpiece. Among them, a clamping wheel group is arranged between the adjusting rod 403 and the supporting column 401, and the angle adjustment of the polishing wheel 404 is achieved by adjusting the clamping position. In addition, the motor 402 drives the polishing wheel 404 to rotate through the cooperation between the gear and the rack to achieve the outer surface polishing operation of the pipeline. Furthermore, a protective cover 405 and a handle 406 are also installed on the polishing wheel 404, and the angle of the polishing wheel 404 is adjusted by the handle 406.

[0045] like Figure 2 , Figure 4 As shown, the polishing mechanism 2 5 includes a polishing wheel 2 503 driven by a motor 2 501 to rotate, and the polishing wheel 2 503 is mounted inside the workpiece, and the polishing wheel 2 503 moves with the moving assembly 9 and passes through the head end and the tail end of the workpiece. Specifically, the polishing wheel 2 503 is connected to the driving end of the motor 2 501 through a support rod and a coupling 502, so that the motor 2 501 drives the polishing wheel 2 503 to rotate to achieve the inner surface polishing operation of the pipeline.

[0046] Furthermore, in order to improve the applicability of the polishing device, polishing wheel 1 404 and polishing wheel 2 503 are both configured as detachable structures.

[0047] like Figure 1 As shown, the material moving assembly 1 12 and the material moving assembly 2 13 both include a slider 102 sliding on a moving track 101, and a lifting clamping assembly 103 is connected to the slider 102, and the clamping assembly 103 clamps and fixes the workpiece through a clamping claw. The main function of the clamping assembly 103 is to clamp and fix the workpiece, and any suitable clamp in the prior art can be used, and its structure is not limited here.

[0048] like Figure 1As shown, the detection mechanism 6 includes two detection cameras 601, one of which is mounted above the workpiece through a bracket 602, and the other is mounted inside the workpiece through a support rod 603 and a connecting rod 604. The two detection cameras 601 move with the moving component 9 and pass through the head and tail ends of the workpiece. Among them, the detection camera 601 is an industrial camera used in the prior art to detect the surface polish of the workpiece, which collects images of the workpiece surface and processes information. The specific process of the workpiece surface detection is not described in detail here.

[0049] Working principle: When the automatic pipeline polishing equipment is in use, transfer racks for loading workpieces are placed next to the polishing station 2 and the inspection station 3. The transfer rack next to the polishing station 2 is used to load the workpieces to be polished, and the transfer rack next to the inspection station 3 is used to load the workpieces that have passed the inspection.

[0050] The material transfer component 12 clamps and transfers the workpiece 1 to the polishing station 2 for polishing operation. After polishing is completed, the material transfer component 2 13 clamps and transfers the workpiece 1 to the inspection station 3. At the same time, the material transfer component 12 clamps and transfers the workpiece 2 to the polishing station 2 for polishing operation. At this time, the workpiece 2 is placed in the polishing station 2, and the workpiece 1 is placed in the inspection station 3. While the workpiece 2 is being polished, the surface of the workpiece 1 is inspected.

[0051] Specifically, the two slides 901 are driven to move by motor four 10, and the polishing mechanism one 4, the polishing mechanism two 5, and the detection mechanism 6 are started at the same time, so that the motor one 402 drives the polishing wheel one 404 to polish the outer surface of the workpiece two, and the motor two 501 drives the polishing wheel two 503 to polish the inner surface of the workpiece two, and the two detection cameras 601 respectively capture images of the inner surface and outer surface of the workpiece one to detect the polishing degree.

[0052] It should be noted that motor three 903 drives the rolling wheel 905 to rotate and drive the workpiece to rotate, and the slide 901 moves to drive the workpiece to move horizontally, so that polishing mechanism one 4 and polishing mechanism two 5 can fully polish the surface of workpiece two, and detection mechanism 6 can fully detect the surface of workpiece one.

[0053] When the surface inspection of workpiece 1 is qualified, material transfer component 2 13 clamps workpiece 1 and transfers it to the next process. At the same time, material transfer component 12 clamps workpiece 2 and transfers it to inspection station 3, then returns to the initial position and clamps workpiece 3 and transfers it to polishing station 2.

[0054] When the surface inspection of workpiece 1 fails, the material transfer component 2 13 clamps and shifts workpiece 1. At the same time, the material transfer component 12 clamps and transfers workpiece 2 to the inspection station 3 and then returns to the initial position to wait. At this time, the material transfer component 2 13 clamps and transfers workpiece 1 to the polishing station 2 for secondary polishing. At this time, workpiece 1 is placed in the polishing station 2, and workpiece 2 is placed in the inspection station 3. While workpiece 1 is undergoing secondary polishing, workpiece 2 undergoes surface inspection.

[0055] Through the mutual cooperation between the mobile component 1 12 and the mobile component 2 13, the loading or unloading of the polishing station 2 and the testing station 3 is realized, so that the polishing station 2 and the testing station 3 can work in coordination.

[0056] The material transfer mechanism 1 is used to realize automatic loading and unloading of workpieces, thereby reducing the degree of manual involvement. The cooperation between the material transfer component 12 and the material transfer component 2 13 enables the polishing station 2 and the inspection station 3 to work together, thereby facilitating timely rework of workpieces that fail polishing. The cooperation between the moving component 9 and the polishing mechanism 1 4 and the polishing mechanism 2 5 enables the outer surface polishing and the inner surface polishing of the pipeline to be carried out simultaneously, thereby greatly improving the polishing efficiency.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
