Description

[Technical field]

[0001] The invention relates to the technical field of tube cylindrical grinding, in particular to a novel grinding head machine. [Background technology]

[0002] In most cases, after the last step of pipe production, the pipe blank will be sawed to the required length to obtain the product. At this time, burrs will be generated at both ends of the pipe due to sawing. Therefore, the ends of the pipe can be grinded by a grinding head machine to eliminate the burrs. Since the burrs are located in the circumferential direction of the pipe, it is necessary to grind one side of the pipe all around to eliminate the burrs. In the existing technology, it is impossible to quickly and fully eliminate the burrs, so the production efficiency is low and the product quality cannot be guaranteed. [Summary of the invention]

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and propose a new type of grinding head machine, which can remove burrs on pipes by grinding once, has high efficiency and ensures high quality of finished products.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A new type of grinding head machine includes a support frame, on which is provided a grinding device for grinding pipes, a conveyor belt arranged at intervals along the axial direction of the pipes, and a floating pressing device. The floating pressing device includes a fixed frame, a pressing plate that can float up and down, and a floating mechanism connected between the pressing plate and the fixed frame. The pressing plate can press the pipe to generate friction between the two so that the pipe can rotate simultaneously during the conveying and grinding process.

[0006] The grinding head machine of the present invention can be operated automatically, and the pipe is transported by a conveyor belt. When the pipe is transported to the grinding device, it can be ground to remove burrs. In order to perform sufficient grinding, the present invention is achieved by arranging a floating pressing device. After the pipe is conveyed to the bottom of the pressing plate, it is pressed by the pressing plate, and friction is generated between the pipe and the pressing plate. Therefore, when the conveyor belt continues to drive, the pipe will roll along the bottom surface of the pressing plate, and the grinding device can complete the sufficient grinding of the circumference of the pipe, eliminate the circumferential burrs, and ensure the quality of the pipe. Only one grinding is required. Grinding can be completed, and multiple pipes can be ground at one time, with high processing efficiency; the pressing plate can float up and down, and the floating mechanism is used to realize the up and down floating function of the pressing plate. When the pipe is transmitted to the bottom of the pressing plate, it can push the pressing plate to lift upward, and the pressing plate will apply a pressure on the pipe that is not less than its own gravity to maintain the friction between the pressing plate and the pipe, thereby ensuring that the pipe can rotate during the transmission process, and under the influence of friction, it will hinder the transmission of the pipe to a certain extent, and it can stay under the pressing plate for a longer time to ensure the grinding quality.

[0007] Furthermore, the distance between the pressing plate and the conveyor belt in the vertical direction is H, and the diameter of the pipe is D. When the pipe does not enter under the pressing plate, H is less than D, and when the pipe enters under the pressing plate, H is equal to D. When H is greater than D, the pipe will not contact the pressing plate during the conveying process, so the pressing plate will not play a role, and the pressing plate can float up and down, and the floating distance is DH.

[0008] Furthermore, the floating press device also includes an adjustment component that can adjust the size of H to correspond to pipes of different diameters. The diameter D of pipes of different specifications may be different, and the adjustment component can adjust the distance H between the press plate and the conveyor belt in the vertical direction, so that when there is no pipe under the press plate, H is less than D, so as to maintain the pressing effect of the press plate on the pipe during the grinding process. If D is much larger than H, it also needs to be adjusted. If D is too large, the pipe will be directly blocked at the side of the press plate during the transmission process and cannot continue to move.

[0009] Furthermore, the floating mechanism includes a plurality of connecting rods movably connected between the pressing plate and the fixed frame, and one of the connecting rods is connected to the adjusting assembly. The connecting rod is connected to the pressing plate and defines a distance H between the pressing plate and the conveyor belt in the vertical direction. Since the connecting rod is movably connected, the pressing plate can float up and down in the vertical direction. The plurality of connecting rods can define the circumferential displacement of the pressing plate to maintain stability during the feeding process. The adjusting assembly is connected to one of the connecting rods. Since the connecting rods are linked to each other, the upward and downward movement of the pressing plate can be controlled and the size of the distance H can be adjusted by simply adjusting the range of motion of the connecting rod.

[0010] Furthermore, the adjustment assembly includes an adjustment rod and an adjustment nut threadedly matched with the adjustment rod. Among the multiple connecting rods connecting the press plate, one connecting rod is connected to the adjustment assembly, wherein the adjusting rod is connected to the connecting rod, and the other end of the adjusting rod is installed with an adjustment nut. The position of the adjusting rod can be changed by turning the adjustment nut, thereby changing the position of the connecting rod connected to the adjusting rod, so as to adjust the distance H between the press plate and the conveyor belt in the vertical direction. The adjustment method is simple and convenient, and the adjustment can be completed quickly to start processing.

[0011] Furthermore, the support frame is provided with two grinding devices and at least two floating pressing devices, and the at least two floating pressing devices and the conveyor belt are located between the two grinding devices. By providing two grinding devices, both ends of the pipe can be directly polished during processing, without the need to polish each end separately, which can save a lot of processes and improve production efficiency. At least two floating pressing devices can ensure that the pipe will not bend or deviate during the conveying process, and the two ends of the pipe can move synchronously.

[0012] Furthermore, the floating mechanism also includes an elastic member, and when the pressing plate floats up and down, the elastic member is compressed and stretched accordingly. As the pipe is conveyed, the pressing plate is lifted upward, and the elastic member is compressed to accumulate elastic potential energy. The elastic force of the elastic member and the gravity of the pressing plate act on the pipe together, strengthening the pressing effect of the pressing plate on the pipe.

[0013] Furthermore, the elastic member is kept in a compressed state to maintain its own elastic potential energy. Under the action of the elastic member, the press plate can generate a large pressure when pressing the pipe, and after adjusting the distance H between the press plate and the conveyor belt in the vertical direction, the elastic member can still be kept in a compressed state to maintain the pressure of the press plate on the pipe.

[0014] Furthermore, the end of the pressing plate has a guide surface, which can facilitate the pipe to lift the pressing plate so as to enter between the pressing plate and the conveyor belt for easy grinding.

[0015] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0036] Embodiment 1

[0037] Reference Figures 1 to 3 The present invention proposes a new type of grinding head machine, including a support frame 100, on which a grinding device 200 for grinding pipes, a conveyor belt 110 arranged at intervals along the axial direction of the pipes, and a floating pressing device 300 are provided. The floating pressing device 300 includes a fixed frame 310, a pressing plate 320 that can float up and down, and a floating mechanism connected between the pressing plate 320 and the fixed frame 310. The pressing plate 320 can press the pipe to generate friction between the two to achieve simultaneous rotation of the pipe during the conveying and grinding process.

[0038] The grinding head machine of the present invention can be operated automatically, and the conveyor belt 110 is used to transport the pipe. When the pipe is transported to the grinding device 200, it can be ground to remove burrs. In order to perform sufficient grinding, the present invention is implemented by setting a floating pressing device 300. After the pipe is transported to the bottom of the pressing plate 320, it is pressed by the pressing plate 320, and friction is generated between the pipe and the pressing plate 320. Therefore, when the conveyor belt 110 continues to drive, the pipe will roll along the bottom surface of the pressing plate 320, and the grinding device 200 can complete the sufficient grinding of the circumference of the pipe and eliminate the circumferential burrs. The quality of the pipe is guaranteed, and only one grinding is required. Multiple pipes can be ground at one time, and the processing efficiency is high. The pressing plate 320 can float up and down. When the pipe is transmitted to the bottom of the pressing plate 320, it can push the pressing plate 320 to lift upward. The pressing plate 320 will apply a pressure on the pipe that is not less than its own gravity to maintain the friction between the pressing plate 320 and the pipe, thereby ensuring that the pipe can rotate during the transmission process, and under the influence of friction, the transmission of the pipe will be hindered to a certain extent, and it can stay under the pressing plate 320 for a longer time to ensure the grinding quality.

[0039] Reference Figure 2, wherein the vertical distance between the pressing plate 320 and the conveyor belt 110 is H, and the diameter of the pipe is D. Before the pipe is conveyed to the bottom of the pressing plate 320, H is less than D. As the pipe is conveyed, the pressing plate 320 is lifted up, and at this time H=D. If H is greater than D, when the pipe is conveyed to the bottom of the pressing plate 320, it will not contact the pressing plate 320, and the size of H will not change. However, since the pipe does not contact the pressing plate 320, no friction will be generated between the two, and it is difficult to ensure that the pipe can be fully polished.

[0040] Since different pipes have different diameters D, in order to enable the equipment to process pipes of various diameters, the floating pressing device 300 also includes an adjusting component that can adjust the size of H. The adjusting component can adjust the distance H in the vertical direction between the pressing plate 320 and the conveyor belt 110. When there is no pipe under the pressing plate 320, H can be kept smaller than D to maintain the pressing effect of the pressing plate 320 on the pipe during the grinding process. If the pipe diameter D is much larger than H, adjustment is also required. The pressing plate 320 is adjusted upward to increase H. When D is too large, the pipe will be directly blocked at the side of the pressing plate 320 during the transmission process and cannot continue to move under the pressing plate 320. It is impossible to grind or transmit. The pressing plate 320 needs to be manually lifted so that the pipe can continue to be transmitted. At this time, after the pressing plate 320 is put down, it can still press the pipe, and the pipe at the rear can also enter under the pressing plate 320 when continuing to be transmitted.

[0041] In order to facilitate the pipe to move to the bottom of the pressure plate 320 and lift it during the transmission process, the end of the pressure plate 320 has a guide surface 321, and the guide surface 321 can be an inclined surface or a curved surface. When the pipe moves to the end of the pressure plate 320, it can continue to move along the guide surface 321, thereby easily lifting the pressure plate 320 to facilitate grinding processing.

[0042] Reference Figure 3, wherein, in order to reduce the workload and improve production efficiency, the grinding head machine of the present invention includes two grinding devices 200, the floating pressing device 300 and the conveyor belt 110 are located between the two grinding devices 200, and the two grinding devices 200 can grind the two ends of the pipe respectively, so that both ends of the pipe can be fully polished after one transmission, and there is no need to grind each end separately once, which can save a lot of processes, greatly improve production efficiency compared to traditional power, and greatly reduce the workload of workers. In addition, in order to ensure that the two ends of the pipe can move synchronously during the transmission process, at least two floating pressing devices 300 are arranged between the two grinding devices 200, which can ensure that the pipe will not bend or deflect during the transmission process. In order to maximize the effect of the pressing plate 320, the pressing plate 320 should correspond to the conveyor belt 110 up and down, that is, when the size of H is 0, the pressing plate 320 is in contact with the conveyor belt 110. In this way, with the support of the conveyor belt 110, the pressing plate 320 will not bend the pipe when pressing the pipe, and can ensure that there is a large friction between the pipe and the pressing plate 320.

[0043] Embodiment 2

[0044] This embodiment specifically describes the structure of the floating mechanism and the adjustment assembly. Specifically: Figure 2 The floating mechanism includes: a first connecting rod 331 and a second connecting rod 332. The adjusting component includes: an adjusting rod 341 and an adjusting nut 342.

[0045] Among them, one end of the first connecting rod 331 is hinged to the pressing plate 320, and the other end is hinged to the fixing frame 310. One end of the second connecting rod 332 is hinged to the pressing plate 320, and the other end is hinged to the adjusting rod 341. In addition, the rod body of the second connecting rod 332 is hinged to the fixing frame 310, and the fixing frame 310 is provided with a boss 311. The adjusting rod 341 is slidably matched with the boss 311, and the adjusting nut 342 is threadedly matched with the adjusting rod 341. The connecting rod is connected to the pressing plate 320 and defines a distance H in the vertical direction between the pressing plate 320 and the conveyor belt 110. Since the connecting rod is a movable connection, the pressing plate 320 can float up and down in the vertical direction. Under the action of the first connecting rod 331 and the second connecting rod 332, the circumferential displacement of the pressing plate 320 can be limited to maintain stability during the feeding process.

[0046] When the pressing plate 320 is not pressing the pipe, the adjusting nut 342 is against the boss 311, stabilizing the adjusting rod 341, the first connecting rod 331 and the second connecting rod 332. As the pipe is conveyed, the pressing plate 320 is lifted by the pipe, and the first connecting rod 331 and the second connecting rod 332 rotate around the hinge with the fixing frame 310. The other end of the second connecting rod 332 pushes the adjusting rod 341 during the rotation, so that the positions of the adjusting rod 341 and the adjusting nut 342 change. At this time, the adjusting nut 342 is away from the boss 311. When the pressing plate 320 is not pressing the pipe, the position of the adjusting rod 341 can be changed by rotating the adjusting nut 342. Since the adjusting rod 341 is connected to the second connecting rod 332, there is a linkage relationship between the first connecting rod 331 and the second connecting rod 332. Therefore, the pressing plate 320 can be controlled to move upward and downward by adjusting the range of motion of the second connecting rod 332, and the size of the distance H can be adjusted. The adjustment method is simple and convenient, and the adjustment can be completed quickly to start processing. And since the pressing plate 320 is connected to the fixed frame 310 through the first connecting rod 331 and the second connecting rod 332, the connection method of the connecting rod is hinged, so the pressing plate 320 has a displacement in the horizontal direction in addition to the displacement in the vertical direction. When the pipe is transmitted to the end of the pressing plate 320, the pressing plate 320 can be pushed to move in the horizontal direction by continuing the transmission, and it is lifted upward while moving, so that the pressing plate 320 can be pressed on the pipe more easily.

[0047] Embodiment 3

[0048] Reference Figure 4 This embodiment proposes another structure of a floating mechanism and an adjusting assembly that is different from the solution in the second embodiment. Specifically, the floating mechanism includes: a third connecting rod 333 and a fourth connecting rod 334. The adjusting assembly includes a threaded sleeve 343.

[0049] The lower ends of the third connecting rod 333 and the fourth connecting rod 334 are connected to the pressing plate 320, the rod body is slidably connected to the fixing frame 310, and the threaded sleeve 343 is installed on the fourth connecting rod 334. When the pressing plate 320 does not press the pipe, the threaded sleeve 343 and the fixing frame 310 are against each other. As the pipe is conveyed, the pressing plate 320 is lifted by the pipe, and the third connecting rod 333 and the fourth connecting rod 334 slide upward with the lifting of the pressing plate 320. At this time, the threaded sleeve 343 is away from the fixing frame 310. Rotating the threaded sleeve 343 can control the movement of the fourth connecting rod 334, thereby controlling the movement of the pressing plate 320 and changing the size of the distance H. The adjustment method is simple and convenient, and is as convenient as the solution in the second embodiment. The disadvantage is that the pipe is not so easy to enter the bottom of the pressing plate 320, and the size of H needs to be set, which should be slightly smaller than the pipe diameter D.

[0050] Embodiment 4

[0051] Reference Figure 2 , this embodiment adds an elastic member 350 on the basis of the second embodiment to enhance the pressure of the pressing plate 320 on the pipe. Since the pressing plate 320 has vertical and horizontal displacements, the pipe will also push the pressing plate 320 to move during the transmission process, so the pressure of the pressing plate 320 on the pipe will be insufficient. This problem can be solved by setting the elastic member 350. The elastic member 350 can be compressed and stretched as the pressing plate 320 floats up and down. The pressing plate 320 is lifted upward, and the elastic member 350 is compressed to accumulate elastic potential energy. The elastic force of the elastic member 350 and the gravity of the pressing plate 320 act on the pipe together to enhance the pressing effect of the pressing plate 320 on the pipe. In addition, since the distance H between the pressing plate 320 and the conveyor belt 110 in the vertical direction is not fixed, in order to ensure that the elastic member 350 can be compressed when the pressing plate 320 is lifted, the elastic member 350 is always kept in a compressed state to maintain its own elastic potential energy, so as to maintain the pressure of the pressing plate 320 on the pipe.

[0052] The elastic member 350 is a spring, which is arranged on the outside of the adjusting rod 341. One end of the spring is against the boss 311, and the other end is against the protruding part at the end of the adjusting rod 341. As the adjusting rod 341 slides, the spring will undergo elastic deformation. Since the adjusting rod 341 is relatively long, even if the spring is always kept in a compressed state, it will not be damaged.

[0053] Embodiment 5

[0054] Reference Figure 5 and 6 In this embodiment, an automatic feeding device 400 and a receiving device 500 are proposed. The automatic feeding device 400 is provided on one side of the support frame 100, which can continuously feed the pipe to the conveyor belt 110. The receiving device 500 is provided on the other side of the support frame 100. The pipe is transmitted on the conveyor belt 110, and continues to be transmitted after being polished by the polishing device 200, and falls from the conveyor belt 110 to the receiving device 500 to complete the collection of the finished product. This is a complete production line. Except for adjusting the height H of the pressing plate 320 and the subsequent transfer of the finished product in the receiving device 500, it can almost achieve automatic production.

[0055] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
