[0014] The present invention provides a grinding machine for a tubular workpiece, which has the following beneficial effects: The grinding machine for tubular workpieces is provided with a positioning mechanism, a processing mechanism and a collecting mechanism to transport, position and collect round tubes. When a round tube polishing machine is used to polish and grind a round tube, the round tube moves forward following the grinding system. During this process, the front end of the round tube is prone to warp up and deviate from the original motion trajectory, resulting in uneven grinding of the round tube. Therefore, a positioning mechanism and a processing mechanism are provided to feed, fix the inside of the round tube and grind the round tube, so that the round tube moves forward at the same horizontal height, and the round tube is prevented from deviating from the original motion trajectory driven by the grinding system, to solve the above problem.

[0015] The grinder for the tubular workpiece is provided with a positioning mechanism to position the round tube in the horizontal direction. When the outside of the round tube is polished, the round tube is easy to follow the movement of the polishing system, the front end is tilted, and it deviates from the original motion trajectory. Therefore, a positioning mechanism and a clamping assembly are provided, the first arc plate is fixed in contact with the inside of the round tube, and the second pipe and the stretching rod can rotate with the round tube, and the stretching rod can be shortened as the round tube moves forward to prevent the round tube from deviating from the original motion trajectory, so as to solve the above problem. A cooling block is provided in the second pipe, and a flow groove is provided inside the second pipe, which can transfer the temperature to the round tube to cool the inside of the round tube.

[0016] The grinding machine for tubular workpieces places the round tube by setting a processing mechanism, and the bottom of the round tube does not contact the through groove, thereby reducing the contact area between the feed pipe and the round tube and promoting heat dissipation of the round tube. After the processing is completed, the round tube can be pressed, the positioning mechanism can be used to separate the round tube, and the round tube can be transported to the second slideway and the collection mechanism to promote the discharge of the round tube.

[0017] The grinding machine for tubular workpieces is equipped with a collection mechanism to uniformly collect and cool the round tubes. After the round tube processing is completed, workers need to manually pick up and organize the round tubes, and reduce the impact between the round tubes and the equipment and the stacking between the round tubes to prevent the round tubes from deforming after the impact. Therefore, a collection mechanism is set up to collect the processed round tubes, and cool the round tubes to accelerate the cooling of the round tubes. After collection, the round tubes are uniformly pushed out to avoid stacking or collision between the round tubes. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] After the polishing work is completed, the tail of the round tube gradually moves to the bottom of the first pressing plate 7047, and the fifth telescopic rod 7045 is adjusted to the initial state. The rubber strips at the bottom of the first pressing plate 7047 and the second pressing plate 7049 gradually contact and press the tail of the round tube to assist the separation of the positioning mechanism 6 from the round tube.

[0028] Then, the sixth telescopic rod 7048 is opened, and the sixth telescopic rod 7048 drives the second pressing plate 7049 to move toward the collecting mechanism 9 . The second pressing plate 7049 drives the round tube to fall into the second slideway 701 , and the front end of the round tube falls into the collecting mechanism 9 .

[0029] A channel is opened inside the movable plate 901, and the second electric push rod 906 is fixedly connected to the outside of the movable plate 901, and the second electric push rod 906 is fixedly connected to the outside of the support plate 907, and the outside of the support plate 907 is fixedly connected to the connecting rod 908, and the outside of the connecting rod 908 is fixedly connected to the third sliding plate 909, and the outside of the third sliding plate 909 is fixedly connected to a rubber ring.

[0031] In the initial state, the placement groove 904 farthest from the first telescopic rod 8 is aligned with the second channel. The second electric push rod 906 is turned on, and the second electric push rod 906 drives the support plate 907, the connecting rod 908 and the third sliding plate 909 to move away from the workbench 2 until the third sliding plate 909 contacts the baffle 905. As the front end of the round tube enters the placement groove 904, the round tube can be manually pushed completely into the placement groove 904, and the front end of the round tube contacts the rubber ring. The first electric push rod 903 is turned on to the first stroke, and the first electric push rod 903 is stuck in the channel to protect the round tube. Then the first telescopic rod 8 is turned on to the second stroke to complete the loading of the other two round tubes.

[0032] When unloading is required, the first telescopic rod 8 is opened to the maximum stroke, the first telescopic rod 8 drives the movable plate 901 to move to the outside of the workbench 2, the first electric push rod 903 is adjusted to the initial state, and then the second electric push rod 906 is adjusted to the initial state, the second electric push rod 906 drives the connecting rod 908 and the third sliding plate 909 to move in the direction of the round tube to push the round tube out.

[0033] The positioning mechanism 6 includes a second telescopic rod 601, the outside of the second telescopic rod 601 is fixedly connected to the third telescopic rod 602, the outside of the third telescopic rod 602 is fixedly connected to the fixed cylinder 603, the inside of the fixed cylinder 603 is provided with a fan, the bottom of the fixed cylinder 603 is fixedly connected to a bent pipe 604, there are three bent pipes 604, and they are evenly arranged, and the second telescopic rod 601 is fixedly connected to the outside of the first slide plate 5.

[0034] When the telescopic column 3 is opened to the first stroke, the elbow 604 is flush with the feed pipe 7041. When the fan is turned on, the gas enters the elbow 604 through the fixed cylinder 603, and then moves to the outside of the feed pipe 7041 and the grinding system 705 through the three elbows 604, supplying air to the feed channel and the grinding system 705, promoting the cooling of the grinding system 705. Since the interior of the fixed plate 702 is hollow, the debris in the feed channel can move outward through the fixed plate 702.

[0035] The outside of the fixed cylinder 603 is fixedly connected to a steering joint 605, the inside of the steering joint 605 is rotatably connected to a first pipe 606, the inside of the first pipe 606 is fixedly connected to a stretching rod 607, the outside of the stretching rod 607 is fixedly connected to a locking assembly 608, and there are three steering joints 605, first pipes 606, stretching rods 607 and locking assemblies 608.

[0036] When the telescopic column 3 is in the second stroke, the stroke of the third telescopic rod 602 is adjusted according to the size of the round tube so that the corresponding positioning assembly 608 is aligned with the round tube.

[0037] The positioning assembly 608 includes a second pipe 6081, a cooling block is placed inside the second pipe 6081, a flow groove 6082 is opened inside the second pipe 6081, an annular plate 6083 is fixedly connected to the outside of the second pipe 6081, and a first arc plate 6084 is fixedly connected to the outside of the annular plate 6083. The first arc plate 6084 is set to be made of rubber material, and the second pipe 6081 is fixedly connected to the outside of the stretching rod 607.

[0038] After selecting a suitable positioning assembly 608, the second telescopic rod 601 is opened, and the second telescopic rod 601 drives the third telescopic rod 602 and the fixing tube 603 to move away from the processing mechanism 7. The second pipe 6081 is manually pulled out of the first pipe 606, and then the buckle is manually clamped on the outside of the stretching rod 607 to fix the position of the stretching rod 607.

[0039] After the round tube is placed, the round tube is manually pressed, and then the stroke of the second telescopic rod 601 is adjusted to restore the second telescopic rod 601 to its initial state, and the second pipe 6081 gradually enters the round tube, and the first arc plate 6084 contacts the inner wall of the round tube. Then, the buckle on the outside of the stretch rod 607 is removed, and as the grinding system 705 drives the round tube to rotate, the round tube drives the first arc plate 6084, the annular plate 6083 and the second pipe 6081 inside to rotate, and the second pipe 6081 drives the stretch rod 607 and the first pipe 606 to rotate, and at this time, the first pipe 606 rotates inside the steering joint 605. As the round tube follows the two grinding wheels to move in the direction of the positioning mechanism 6, the stretch rod 607 is gradually squeezed and begins to shorten.

[0040] The processing mechanism 7 is turned on to press the round tube, and then the second telescopic rod 601 is turned on. The second telescopic rod 601 drives the third telescopic rod 602, the fixing tube 603 and the positioning assembly 608 to move away from the round tube until the positioning assembly 608 is separated from the round tube.

[0041] Working principle: Before using the equipment, open the telescopic column 3 to the first stroke, and the telescopic column 3 drives the first slide plate 5 and the positioning mechanism 6 to move downward to process the inside of the processing mechanism 7. When the telescopic column 3 is opened to the first stroke, the elbow 604 is flush with the feed pipe 7041. Turn on the fan, the gas enters the elbow 604 through the fixed cylinder 603, and then moves to the outside of the feed pipe 7041 and the grinding system 705 through the three elbows 604, supplying air to the feed channel and the grinding system 705, promoting the cooling of the grinding system 705. Since the interior of the fixed plate 702 is hollowed out, the debris in the feed channel can move outward through the fixed plate 702.

[0042] Then manually place the round tube to be polished in the processing mechanism 7, and manually place the round tube in the feed pipe 7041. At this time, the bottom round tube is on the positioning plate 7043 and does not contact the through groove 7042. Open the telescopic column 3 to the second stroke, and the telescopic column 3 drives the first slide plate 5 and the positioning mechanism 6 to continue to move downward. According to the size of the round tube, adjust the stroke of the third telescopic rod 602 so that the corresponding positioning assembly 608 is aligned with the round tube. After selecting a suitable positioning assembly 608, open the second telescopic rod 601, and the second telescopic rod 601 drives the third telescopic rod 602 and the fixed cylinder 603 to move away from the processing mechanism 7. Manually pull the second pipe 6081 out of the first pipe 606, and then manually clamp the buckle on the outside of the stretching rod 607 to fix the position of the stretching rod 607.

[0043] After the position of the round tube is properly placed, the round tube is manually pressed to fix the position of the round tube, and then the stroke of the second telescopic rod 601 is adjusted to restore the second telescopic rod 601 to its initial state, and the second pipe 6081 gradually enters the round tube, and the first arc plate 6084 contacts the inner wall of the round tube. Then, the buckle on the outside of the stretch rod 607 is removed, and as the grinding system 705 drives the round tube to rotate, the round tube drives the first arc plate 6084, the annular plate 6083 and the second pipe 6081 inside to rotate, and the second pipe 6081 drives the stretch rod 607 and the first pipe 606 to rotate, and at this time, the first pipe 606 rotates inside the steering joint 605. As the round tube follows the two grinding wheels to move in the direction of the positioning mechanism 6, the stretch rod 607 is gradually squeezed and begins to shorten.

[0044] The grinding system 705 is turned on to complete the grinding work. After the work is completed, the positioning mechanism 6 and the processing mechanism 7 are adjusted to separate the positioning mechanism 6 from the round tube. The processing mechanism 7 is turned on to press the round tube, and then the second telescopic rod 601 is turned on. The second telescopic rod 601 drives the third telescopic rod 602, the fixing cylinder 603 and the positioning assembly 608 to move away from the round tube until the positioning assembly 608 is separated from the round tube.

[0045] Then, the sixth telescopic rod 7048 is opened, and the sixth telescopic rod 7048 drives the second pressing plate 7049 to move in the direction of the collecting mechanism 9. The second pressing plate 7049 drives the round tube to fall into the second slideway 701, and the front end of the round tube falls into the collecting mechanism 9. The processing mechanism 7 and the collecting mechanism 9 are opened to collect the processed round tubes in a unified manner. In the initial state, the placement groove 904 farthest from the first telescopic rod 8 is aligned with the second channel. The second electric push rod 906 is opened, and the second electric push rod 906 drives the support plate 907, the connecting rod 908 and the third sliding plate 909 to move in the direction away from the workbench 2 until the third sliding plate 909 contacts the baffle 905. As the front end of the round tube enters the placement groove 904, the round tube can be manually pushed completely into the placement groove 904, and the front end of the round tube contacts the rubber ring. The first electric push rod 903 is opened to the first stroke, and the first electric push rod 903 is stuck in the channel to protect the round tube. Then the first telescopic rod 8 is opened to two strokes to complete the loading of the other two round tubes.
