Description

Technical Field

[0001] This utility model belongs to the technical field of variable diameter pipe processing equipment, specifically a polishing device for the production of special variable diameter pipes. Background Technology

[0002] A reducing pipe is a pipe that connects pipe sections of different diameters in series. The pressure loss of the fluid in each branch pipe is equal, and the flow rate at the pipe connection point is equal to the sum of the flow rates of each branch pipe.

[0003] Currently, when producing reducers, operators often need to use polishing devices. However, while existing polishing devices have basic polishing functions, they lack corresponding baffles during operation. This causes sparks generated around the reducer end face to fly onto the operator's body, posing a certain operational hazard. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a polishing device specifically designed for the production of variable diameter pipes, which has the advantage of blocking sparks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polishing device for producing special variable diameter pipes, comprising a base, a connecting frame fixedly installed at the rear of the top of the base, a pneumatic cylinder fixedly installed at the front of the top of the connecting frame, the bottom end of the pneumatic cylinder passing through the connecting frame and extending to the outside of the top of the inner surface of the connecting frame and fixedly connected to a first motor, a rotating shaft fixedly sleeved at the other end of the output shaft of the first motor, a polishing disc fixedly connected at the bottom end of the rotating shaft, a second motor fixedly installed on the back of the base, a rotating shaft fixedly sleeved at the other end of the output shaft of the second motor, a hollow block fixedly sleeved on the outer surface of the rotating shaft, a circular block movably sleeved inside the hollow block, and a movable frame fixedly connected to the other end of the circular block.

[0006] As a preferred embodiment of this utility model, short slots are provided on both the left and right sides of the top of the base, and there are two short slots. The two short slots are the same size. A third motor is fixedly installed on the left side of the base. A bidirectional threaded screw is fixedly sleeved on the other end of the output shaft of the third motor. The right end of the bidirectional threaded screw passes through the base and extends to the right side of the inner surface of the base and is movably connected to the right side of the inner surface of the base.

[0007] As a preferred embodiment of this utility model, the left and right sides of the outer surface of the bidirectional threaded screw are threaded with movable blocks, and there are two movable blocks. The tops of the two movable blocks pass through the two short slots and extend to the outside of the tops of the two short slots. The outer surfaces of the two movable blocks are movably connected to the inner surfaces of the two short slots.

[0008] In a preferred embodiment of this invention, a moving block is movably mounted on the top of the opposite surfaces of the two moving blocks, and the number of the two moving blocks is two, with the two moving blocks having the same size.

[0009] As a preferred embodiment of this invention, each of the two moving blocks has a clamping block fixedly connected to its opposite face, and the number of clamping blocks is two. The opposite faces of the two clamping blocks are movably connected to the opposite faces of the two moving blocks.

[0010] As a preferred embodiment of this invention, each of the two moving blocks has a moving rod movably installed inside it. There are two moving rods in total. The other end of each of the two moving rods passes through the two moving blocks and the two movable blocks in sequence and extends to the outside of the bottom end of the two movable blocks and is fixedly connected to a connecting block. There are two connecting blocks in total, and the two connecting blocks are of the same size.

[0011] As a preferred embodiment of this utility model, springs are movably sleeved on the outer surfaces of both moving rods. There are two springs in total. One end of each spring is fixedly connected to the bottom end of the two moving blocks, and the other end of each spring is fixedly connected to the top end of the two connecting blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting a second motor, a hollow block, a round block, and a movable frame, allows the operator to start the second motor, which will cause the rotating shaft and the hollow block to rotate. This causes the inner surface of the round block to press and push the outer surface of the round block, which in turn causes the round block to drive the movable frame to move downward. This allows the movable frame to block the sparks generated when the bottom of the polishing disc polishes the end face of the variable diameter pipe, thus bringing convenience to the operator.

[0014] 2. This utility model, by setting up moving rods, connecting blocks, and springs, allows the operator to pull the two connecting blocks, causing the two moving rods to move downwards. This causes one end of the two moving rods to detach from the inside of the two moving blocks, thereby releasing the fixing effect on the two moving blocks and the two clamping blocks. At this time, the two springs will be stretched, and the operator can then disassemble and replace the two moving blocks and the two clamping blocks as a whole. This allows the two clamping blocks to clamp and fix different types of reducers, thus increasing the application range of the device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a polishing device for producing special variable diameter pipes, including a base 1, a connecting frame 2 fixedly installed at the rear of the top of the base 1, a pneumatic cylinder 3 fixedly installed at the front of the top of the connecting frame 2, the bottom end of the pneumatic cylinder 3 passing through the connecting frame 2 and extending to the outside of the top of the inner surface of the connecting frame 2 and fixedly connected to a first motor 4, the other end of the output shaft of the first motor 4 is fixedly sleeved with a rotating shaft 5, the bottom end of the rotating shaft 5 is fixedly connected to a polishing disc 6, a second motor 7 is fixedly installed on the back of the base 1, the other end of the output shaft of the second motor 7 is fixedly sleeved with a rotating shaft 8, a hollow block 9 is fixedly sleeved on the outer surface of the rotating shaft 8, a round block 10 is movably sleeved inside the hollow block 9, and the other end of the round block 10 is fixedly connected to a movable frame 11.

[0023] When the operator starts the second motor 7, the rotating shaft 8 and the hollow block 9 will rotate, causing the inner surface of the hollow block 9 to press and push the outer surface of the round block 10, which in turn causes the round block 10 to drive the movable frame 11 to move downwards. This allows the movable frame 11 to block the sparks generated around the end face of the variable diameter tube when the polishing disc 6 polishes it.

[0024] The base 1 has two short slots 12 on the left and right sides of its top end. The two short slots 12 are the same size. A third motor 13 is fixedly installed on the left side of the base 1. A bidirectional threaded screw 14 is fixedly sleeved on the other end of the output shaft of the third motor 13. The right end of the bidirectional threaded screw 14 passes through the base 1 and extends to the right side of the inner surface of the base 1 and is movably connected to the right side of the inner surface of the base 1.

[0025] When the operator starts the third motor 13, the bidirectional threaded screw 14 will rotate.

[0026] Among them, the left and right sides of the outer surface of the bidirectional threaded screw 14 are threaded with moving blocks 15. There are two moving blocks 15. The top of each moving block 15 passes through the two short slots 12 and extends to the outside of the top of the two short slots 12. The outer surface of each moving block 15 is movably connected to the inner surface of the two short slots 12.

[0027] When the bidirectional screw 14 rotates, the two moving blocks 15 will move in opposite directions.

[0028] Among them, two moving blocks 16 are movably installed on the top of the opposite sides of the two moving blocks 15. There are two moving blocks 16, and the two moving blocks 16 are the same size.

[0029] When the two moving blocks 15 move toward each other, they will cause the two moving blocks 16 to move relative to each other.

[0030] In this arrangement, two clamping blocks 17 are fixedly connected to the opposite faces of the two moving blocks 16. There are two clamping blocks 17 in total, and the opposite faces of the two clamping blocks 17 are movably connected to the opposite faces of the two moving blocks 15.

[0031] When the two moving blocks 16 drive the two clamping blocks 17 to move together, the two clamping blocks 17 will be able to clamp and fix the reducing pipe.

[0032] Each of the two moving blocks 16 has a moving rod 18 movably installed inside it. There are two moving rods 18. The other end of each moving rod 18 passes through the two moving blocks 16 and the two moving blocks 15 in sequence and extends to the outside of the bottom end of the two moving blocks 15 and is fixedly connected to a connecting block 19. There are two connecting blocks 19, and the two connecting blocks 19 are the same size.

[0033] When one end of the two moving rods 18 is inside the two moving blocks 16, it will have a fixing effect on the two moving blocks 16 and the two clamping blocks 17.

[0034] Two springs 20 are movably sleeved on the outer surfaces of the two moving rods 18. One end of each spring 20 is fixedly connected to the bottom end of the two moving blocks 15, and the other end of each spring 20 is fixedly connected to the top end of the two connecting blocks 19.

[0035] The design of the two springs 20 effectively resets the movement of the two moving rods 18 and the two connecting blocks 19.

[0036] Working principle and usage process of this utility model:

[0037] First, the operator operates the third motor 13, causing the bidirectional threaded screw 14 to rotate, which in turn causes the two moving blocks 15 to move towards each other, thereby allowing the two clamping blocks 17 to clamp and fix the reducing pipe. Then, the operator operates the second motor 7, the first motor 4, and the pneumatic cylinder 3. The operation of the second motor 7 causes the rotating shaft 8 and the hollow block 9 to rotate, which causes the interior of the hollow block 9 to squeeze and push the outer surface of the round block 10, thereby causing the round block 10 to drive the movable frame 11 to move downward, so that the short groove 12 can block the sparks generated by the polishing disc 6 when polishing the end face of the reducing pipe. The operation of the first motor 4 causes the rotating shaft 5 and the polishing disc 6 to rotate, while the operation of the pneumatic cylinder 3 causes the rotating shaft 5 to move downward, thereby allowing the polishing disc 6 to polish the end face of the reducing pipe.

[0038] When the operator needs to clamp and polish different types of reducers, the operator pulls the two connecting blocks 19, which will cause the two moving rods 18 to move downwards. When one end of the two moving rods 18 disengages from the inside of the two moving blocks 16, the fixation of the two moving blocks 16 and the two clamping blocks 17 will be released. Then the operator can disassemble and replace them so that they can clamp and fix different types of reducers.
