DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] A hydraulic cylinder end processing device, such as Figure 1 and Figure 2 , including a fixed plate 1, a movable plate 2, and a left plate 3 and a right plate 4 relatively arranged at the top of the fixed plate 1, a hanging plate 5 is provided on the upper side of the left plate 3 close to the right plate 4, and a placement plate 6 for placing the cylinder is provided on the rear side of the hanging plate 5, which is inclined upward, and the movable plate 2 is located at the lower front side of the hanging plate 5. A first cylinder 7 for pushing the movable plate 2 to move vertically up and down is provided on the fixed plate 1, a transfer member for transferring the cylinder on the placement plate 6 to the movable plate 2 is provided on the hanging plate 5, and a clamping member for clamping the cylinder is provided on the movable plate 2. The right plate 4 is horizontally slidably connected to the fixed plate 1 through a movable member, and a first motor 8 is provided on the right plate 4, and one end of the rotating shaft of the first motor 8 passes through the right plate 4 and is provided with a grinding wheel 9.
[0022] like Figure 1 and Figure 2 When in use, multiple cylinders are placed on the placement plate 6, and then the piston rod of the first cylinder 7 pushes the movable plate 2 to move upward to a suitable position, and then a cylinder on the placement plate 6 is transferred to the movable plate 2 by the transfer member, and then clamped by the clamping member. At this time, the two ends of the cylinder that need to be polished are respectively suspended on both sides of the movable plate 2, and then the piston rod of the first cylinder 7 drives the movable plate 2 to move downward until the cylinder corresponds to the grinding wheel 9, and then the first motor 8 is turned on, and the rotating shaft of the first motor 8 drives the grinding wheel 9 to rotate, and then the right side plate 4 is driven by the moving member to approach the left side plate 3 until the grinding wheel 9 contacts the end of the cylinder to grind the end of the cylinder. There is no need to manually grind the end of the cylinder, which saves manpower and improves the efficiency of grinding the end of the cylinder. There is no need to manually place the cylinder on the movable plate 2, and it is simple and convenient to use.
[0023] like Figure 1 and Figure 3The transfer member includes a baffle 10 arranged at the top of the movable plate 2, and the baffle 10 contacts the front side of the hanging plate 5. An end of the hanging plate 5 close to the placement plate 6 is opened with a material discharge trough 12, and the baffle 10 closes the notch of the material discharge trough 12. A placement groove 13 is provided on the side of the movable plate 2 close to the hanging plate 5, and the left and right sides of the placement groove 13 are connected to the movable plate 2. The clamping member is used to clamp the cylinder in the placement groove 13. The clamping member includes a clamping plate 14 placed in the placement groove 13. The bottom end of the movable plate 2 is provided with a second cylinder 15 for pushing the clamping plate 14 to move vertically up and down.
[0024] like Figure 1 and Figure 3 When it is necessary to transfer a cylinder on the placement plate 6 to the mobile plate 2, the piston rod of the first cylinder 7 is used to push the mobile plate 2 upward. At this time, the baffle 10 will move with the mobile plate 2. When the baffle 10 releases the closure of the slot of the material discharge trough 12, and the placement slot 13 on the mobile plate 2 is connected to the material discharge trough 12, because the placement plate 6 is tilted upward, a cylinder on the placement plate 6 close to the material discharge trough 12 will pass through the material discharge trough 12 and roll onto the clamping plate 14 in the placement slot 13. At this time, the two ends of the cylinder on the clamping plate 14 that need to be polished Then, the piston rod of the second cylinder 15 pushes the clamping plate 14 to move upward until the outer wall of the cylinder on the clamping plate 14 contacts and presses against the top groove wall in the placement groove 13. At this time, the clamping of the cylinder can be completed, reducing the displacement of the cylinder when grinding the cylinder. Then, the piston rod of the first cylinder 7 drives the movable plate 2 to move downward until the cylinder corresponds to the grinding wheel 9. At this time, the movable plate 2 will be located below the front side of the hanging plate 5. The hanging plate 5 will not affect the grinding of the cylinder by the grinding wheel 9. It is simple and convenient to use.
[0025] like Figure 1 and Figure 2 The bottom end of the baffle 10 is rotatably connected to the top end of the movable plate 2. An embedding groove 16 is provided on the side of the baffle 10 facing away from the suspension plate 5. A second motor 17 for driving the movable plate 2 to rotate is provided on the bottom groove wall of the embedding groove 16. A turntable 18 is rotatably connected to the bottom end of the movable plate 2. The piston rod of the first cylinder 7 is fixedly connected to the bottom end of the turntable 18. The rotation axis of the movable plate 2 on the baffle 10 coincides with the rotation axis of the turntable 18.
[0026] like Figure 1 and Figure 2When the grinding of one end of the cylinder is completed, the right side plate 4 is driven away from the left side plate 3 by the moving part, and then the second motor 17 is turned on. The rotating shaft of the second motor 17 drives the moving plate 2 to rotate 180 degrees, so that the other end of the cylinder to be ground corresponds to the grinding wheel 9, and then the right side plate 4 is driven close to the left side plate 3 by the moving part again until the grinding wheel 9 contacts the end of the cylinder to grind the end of the cylinder. The grinding of the two ends of the cylinder can be completed without removing the cylinder. The second motor 17 is a servo motor;
[0027] When the rotating shaft of the second motor 17 drives the movable plate 2 to rotate, the baffle 10 will not rotate because it is in contact with the front side of the hanging plate 5. Also, when the cylinder barrel corresponds to the grinding wheel 9, the movable plate 2 is located below the front side of the hanging plate 5, so the hanging plate 5 will not affect the rotation of the movable plate 2, and it is simple and convenient to use.
[0028] like Figure 1 and Figure 3 Two opposite right-angled triangular plates 19 are provided on the bottom wall of the placement groove 13, the clamping plate 14 is located above the two right-angled triangular plates 19, and two opposite collecting boxes 20 are provided on the fixed plate 1, and the two collecting boxes 20 are respectively located on the front and rear sides of the first cylinder 7, and the inclined surfaces of the two right-angled triangular plates 19 face upward.
[0029] like Figure 1 and Figure 3 When the cylinder barrel is polished, the piston rod of the second cylinder 15 pushes the clamping plate 14 to move downward until the clamping plate 14 enters between the two right-angled triangular plates 19. At this time, the cylinder barrel on the clamping plate 14 contacts the inclined surfaces of the two right-angled triangular plates 19, and then rolls out of the placement groove 13 through the inclined surfaces of the right-angled triangular plates 19. The cylinder barrel that rolls out of the placement groove 13 falls into one of the collection boxes 20 for collection. Because the rotating shaft of the second motor 17 can drive the moving plate 2 to rotate 180 degrees, the two collection boxes 20 can collect the polished cylinder barrel, and there is no need to manually remove the polished cylinder barrel from the placement groove 13.
[0030] The two collection boxes 20 can also be used to collect qualified and unqualified cylinders after grinding. At this time, a detection mechanism 24 corresponding to the grinding wheel 9 is provided on the side of the left plate 3 close to the right plate 4. When one end of the cylinder is polished and the movable plate 2 is rotated 180 degrees so that the other end of the cylinder that needs to be polished corresponds to the grinding wheel 9, the polished end of the cylinder will correspond to the detection mechanism 24. At this time, the polished end of the cylinder can be detected by the detection mechanism 24. When the other end of the cylinder that needs to be polished is polished, the movable plate 2 is rotated 180 degrees so that the other end of the cylinder that needs to be polished corresponds to the grinding wheel 9. Plate 2 rotates 180 degrees again so that the other polished end of the cylinder is inspected corresponding to the detection mechanism 24. After the two ends of the cylinder are polished and inspected, through the cooperation of the second motor 17, the movable plate 2, the right-angled triangle plate 19, the second cylinder 15 and the clamping plate 14, the two types of cylinders that pass and fail the inspection can be stored in two collection boxes 20 respectively. The detection mechanism 24 is the detection mechanism in the steel pipe grinding detection device with application number CN202022892339.0, and this application will not repeat it here.
[0031] like Figure 1 and Figure 2 The moving part includes an elongated groove 21 arranged at the top of the fixed plate 1 and a slider 22 horizontally slidably connected to the elongated groove 21. The right side plate 4 is fixedly connected to the slider 22. The fixed plate 1 is provided with a third cylinder 23 for pushing the right side plate 4 to move horizontally. The end of the placement plate 6 away from the hanging plate 5 is provided with two opposite legs, and the bottom ends of the two legs are fixedly connected to the top of the fixed plate 1. The purpose of this arrangement is that by opening the third cylinder 23, the piston rod of the third cylinder 23 will push the right side plate 4 to drive the slider 22 to move horizontally in the elongated groove 21 toward or away from the left side plate 3, which is simple and convenient to use.
[0032] The first cylinder 7, the second cylinder 15 and the third cylinder 23 can all be electric cylinders.
[0033] A retaining ring 25 is provided on the right side plate 4, and the grinding wheel 9 is coaxially located in the retaining ring 25. When one end of the cylinder barrel contacts the grinding wheel 9, the other end of the cylinder barrel will enter the retaining ring 25. At this time, the retaining ring 25 can block the flying chips generated when the grinding wheel 9 grinds one end of the cylinder barrel, thereby improving the safety of use.
[0034] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
