Description

Technical Field

[0001] The invention relates to the technical field of common rail pipe processing, in particular to a deburring device used for processing a common rail pipe of an engine. Background Art

[0002] The common rail pipe distributes the high-pressure fuel provided by the high-pressure fuel pump to each injector after voltage stabilization and filtering, and acts as a pressure accumulator. During the cutting process of the common rail pipe, there will be many burrs on the outer circle of its port. Deburring equipment is needed to deburr the outer circle of the cut common rail pipe port.

[0003] In the prior art, the deburring equipment for processing the common rail pipe rotates the threaded shafts on both sides, and drives the clamping plates on both sides to move toward each other through the threaded shafts, so as to clamp and fix the common rail pipe arranged between the clamping plates, and make the suction cup fit the side wall of the common rail pipe. In this process, the movable rod and the adsorption block will be pressed into the inside of the clamping plate, and drive the piston plates on both sides to move back to each other. When the piston plates on both sides move back to each other, the gas inside the air cavity can be drawn into the cavity through the telescopic hose, so that a negative pressure environment is formed inside the air cavity, and then the common rail pipe is adsorbed and fixed under the cooperation of the suction cup, so as to improve the fixing effect of the common rail pipe, avoid the common rail pipe from being offset during the deburring process, and thus ensure the deburring effect of the common rail pipe;

[0004] However, when the common rail pipe is fixed and the outer circle of the port after cutting of the common rail pipe is deburred by a rotating silicon carbide brush, the burr debris generated during the deburring process can easily enter the common rail pipe, affecting the normal operation of the common rail pipe. Therefore, there is room for improvement. Summary of the invention

By moving the retaining pieces 9 and the connecting belt 10 closely adhering to the inner wall of the common rail pipe, the burr debris entering the common rail pipe can be taken out, improving the processing quality.

[0037] See Figures 1 - 12 , the feeding structure includes a rotating rod 24 rotatably passing through the upper rear edge of the processing box 1. A driving structure is arranged at a position on the processing box 1 close to the right end of the rotating rod 24. A rotating cylinder 25 is fixedly sleeved in the middle of the rotating rod 24. Multiple rotating plates 26 are respectively connected to both ends of the rotating cylinder 25. Multiple rotating plates 26 in each group are circumferentially and equally angularly distributed on the rotating cylinder 25. A placing block 29 is connected to one end of each rotating plate 26 away from the rotating cylinder 25. A guiding groove 27 is opened at a position on the rotating plate 26 close to the placing block 29. A moving block 28 is slidably arranged in the guiding groove 27. A clamping block 30 is installed on the moving block 28. Clamping grooves are respectively opened on the side surfaces of the clamping block 30 and the placing block 29 close to each other.

Through the second gear 40 and the third gear 41, the rotating rod 24, the rotating cylinder 25 and the rotating plate 26 are driven to rotate integrally to load the common rail tube. During the rotation of the common rail tube, the two ends of the common rail tube slide on the guide parts 38 of the two guide strips 37, so as to automatically adjust the position of the common rail tube on the placing block 29. After the adjustment, with the continuous rotation of the rotating rod 24, the end parts of the through rods 49 are driven to slide in the first arc groove 33, the first communication groove 34 and the second arc groove 35. During this process, the through rods 49 automatically drive the clamping blocks 30 on the moving blocks 28 to move towards the side close to the placing block 29, so as to automatically clamp and fix the common rail tube on the placing block 29. And after deburring, with the continuous rotation of the rotating rod 24, the end parts of the through rods 49 are driven to slide in the second arc groove 35, the second communication groove 36 and the first arc groove 33, so as to push the moving blocks 28 and the clamping blocks 30 to move reversely and reset to release the common rail tube.

[0042] See Figure 1 and Figure 2 , the collection structure includes a collection box 46 movably inserted into the lower part inside the processing box 1. An opening 47 for the collection box 46 to pass through is provided at the lower part of the front side surface of the processing box 1. A handle 48 is installed in the middle of the front surface of the collection box 46. The collection box 46 can be used to collect the burrs generated during the deburring process, which is convenient for centralized treatment.

[0043] The implementation principle of a deburring device for engine common rail pipe processing in an embodiment of the present invention is as follows: First, place the common rail pipe to be processed on the corresponding two placing blocks 29 at the rear of the processing box 1. Start the second motor 39. Through the second gear 40 and the third gear 41, drive the overall rotation of the rotating rod 24, the rotating cylinder 25, and the rotating plate 26, driving the common rail pipe to rotate and be fed. When the rotating plate 26 rotates, the end of the common rail pipe first slides on the guiding strip 37 of the fixed disk 31. Utilizing the guiding effect of the guiding portion 38 on the guiding strip 37, automatically adjust the position of the common rail pipe on the placing block 29. After the position adjustment, as the common rail pipe continues to rotate, drive the end of the through rod 49 to slide from the first arc-shaped groove 33 and the first communication groove 34 into the second arc-shaped groove 35. During this process, the through rod 49 drives the moving block 28 and the clamping block 30 to move as a whole towards one side of the placing block 29, thereby clamping and fixing the common rail pipe on the placing block 29. When the clamped and fixed common rail pipe rotates to the position between the two silicon carbide brushes, the rotating rod 24 stops rotating. Start the first electric telescopic rod 2 on the processing box 1, driving the overall movement of the first moving disk 4 and the second moving disk 6 towards the end of the common rail pipe, thereby driving the silicon carbide brush on the rotating sleeve 18 to move and tightly adhere to the outer circumference of the port of the common rail pipe. At this time, the second moving disk 6 drives the fixed cylinder 8 and the retaining plate 9 to move as a whole and insert into the common rail pipe. Then start the second electric telescopic rod 7, driving the driving ring 17 at one end of the driving rod 15 to move towards the side of the retaining plate 9 within the fixed cylinder 8. Utilizing the extrusion of the driving ring 17 on the inner wall of the guiding groove 12 on the first connecting strip 11, push multiple retaining plates 9 to move synchronously in a direction away from each other with the connecting belt 10, so that the retaining plates 9 and the connecting belt 10 move as a whole and tightly adhere to the inner wall of the common rail pipe, playing a role of blocking at the inner wall end of the common rail pipe. Then start the first motor 22 on the mounting plate 21, driving the overall rotation of the rotating sleeve 18 and the silicon carbide brush through the first gear 23 and the rotating ring 20 to perform the deburring processing work. At the end of the work, the first electric telescopic rod 2 drives the first moving disk 4 and the second moving disk 6 to move in the reverse direction and reset. By moving the retaining plates 9 and the connecting belt 10 tightly adhering to the inner wall of the common rail pipe, the burr debris entering the common rail pipe can be taken out, improving the processing quality. Then the rotating rod 24 continues to rotate, driving one end of the through rod 49 to slide from the second arc-shaped groove 35 and the second communication groove 36 into the first arc-shaped groove 33. During this process, the through rod 49 drives the moving block 28 to move in the reverse direction and reset on the rotating plate 26, automatically loosening the deburred common rail pipe, causing the common rail pipe to fall onto the rotating conveyor belt 45 for discharging. In this way, the deburring work of the common rail pipe can be achieved.

[0044] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
