Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe clamping technology, specifically a steel pipe clamping and positioning fixture with a V-groove. Background Technology
[0002] During steel pipe processing, the steel pipe needs to be clamped and fixed in order to ensure processing accuracy, including cutting, welding, and drilling.
[0003] In related technologies, a solution for a machine tool drilling workpiece fixture (publication number CN117773196A) was found. The fixture is convenient for installing workpieces and is particularly suitable for round tubular workpieces. Furthermore, the fixture can perform positioning tests on the installed workpieces through a detection unit. The positioning test does not require much manual intervention and can be performed automatically, thus making it more convenient to perform drilling processing on round tubular workpieces.
[0004] However, the above solution uses V-shaped support plates, which are used to place steel pipes. The shape of the support plates is fixed, and the contact area with the steel pipe is limited, resulting in limited support for the steel pipe. The fixed V-angle is only suitable for steel pipes of certain diameters. If the diameter of the steel pipe deviates significantly or if different specifications of steel pipe need to be replaced, support mismatch problems are likely to occur, resulting in insufficient compatibility. Utility Model Content
[0005] The purpose of this utility model is to provide a steel pipe clamping and positioning fixture with a V-groove to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe clamping and positioning fixture with a V-groove, including a base, on which a plurality of symmetrically arranged inclined clamping plates are installed, and a plurality of crescent blocks are rotatably connected to the inclined clamping plates. The crescent blocks can adapt to steel pipes of different thicknesses and can provide multi-point support for the steel pipe, making the support more stable.
[0007] An n-shaped frame is provided, on which a clamping cylinder is installed. A buffer clamping plate is connected to the lower end of the clamping cylinder. The buffer clamping plate can prevent excessive clamping of the steel pipe and prevent the steel pipe from deforming.
[0008] A push cylinder is connected to a synchronizer, which is connected to two corresponding inclined clamping plates to adjust the spacing between the inclined clamping plates, making it easier to clamp and fix more steel pipes.
[0009] Furthermore, the buffer clamping plate includes a fixed plate and a movable plate. The movable plate is slidably connected to the fixed plate via a plug rod. A spring is sleeved on the plug rod. The movement of the fixed plate can compress the spring, and the elastic force of the spring is used to clamp the steel pipe. The movement of the movable plate relative to the fixed plate will not excessively clamp the steel pipe, and there will be no problem of bending for thinner steel pipes.
[0010] Furthermore, the moving plate surface is provided with a safety block located below the fixed plate, and the fixed plate surface is provided with a pressure sensor located above the safety block. The pressure sensor detects the pressure on the steel pipe, and when the pressure is too high, the clamping cylinder automatically controls the moving plate to move upward to prevent damage to the steel pipe.
[0011] Furthermore, the base surface is provided with two strip-shaped holes, and the side of the inclined clamping plate is provided with a movable seat. The movable seat passes through the strip-shaped holes and is connected to a synchronizer and a push cylinder. The synchronizer includes a turntable and two connecting rods connected to the turntable. The connecting rods are rotatably connected to the movable seat. The movable seat is moved by the push cylinder. The synchronous movement of the two movable seats and the inclined clamping plate is achieved by means of the connecting rods and the turntable. The spacing of the inclined clamping plates can be changed to meet different clamping requirements.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] (1) Several crescent blocks are rotated and installed on the inclined clamping plate. The crescent blocks provide multi-point support for the steel pipe, providing a larger support area for the steel pipe. The crescent blocks can support steel pipes of different thicknesses. Together with the clamping cylinder and the moving plate, the steel pipe is clamped to achieve the purpose of stable clamping of the steel pipe.
[0014] (2) The push cylinder can control the sliding of the inclined plate and change the distance between the two inclined plates. It can clamp steel pipes of different thicknesses, with a wider range of applications and can meet various clamping needs.
[0015] (3) The pressing cylinder controls the moving plate to move down. The moving plate can move up and down relative to the fixed plate. When pressing the steel pipe, the movable moving plate will not press the steel pipe too much, thus avoiding the problem of the steel pipe bending. 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] Example:
[0023] Please see Figure 1-4 This utility model provides a technical solution: a steel pipe clamping and positioning fixture with a V-groove, including a base 1, on which a plurality of symmetrically arranged inclined clamping plates 10 are installed, and a plurality of crescent blocks 12 are rotatably connected to the inclined clamping plates 10. The inclined surfaces of the inclined clamping plates 10 are curved, and can clamp and fix steel pipes of different thicknesses in conjunction with the crescent blocks 12. The crescent blocks 12 have arc-shaped openings, which can better fit with the steel pipe and provide stable support for the steel pipe.
[0024] n-shaped frame 2, on which a clamping cylinder 3 is installed, and a buffer clamping plate is connected to the lower end of the clamping cylinder 3. The buffer clamping plate has a buffering effect during the clamping process of the steel pipe to avoid bending the steel pipe.
[0025] A push cylinder 13 is connected to a synchronizer, which is connected to two corresponding inclined clamping plates 10. The push cylinder 13 controls the distance between the two inclined clamping plates 10 through the synchronizer, so that the two inclined clamping plates 10 can clamp the steel pipe more widely.
[0026] In this embodiment, as Figure 4 As shown, the buffer clamping plate includes a fixed plate 4 and a movable plate 5. The movable plate 5 is slidably connected to the fixed plate 4 through a plug rod 7. A spring 8 is sleeved on the plug rod 7. When the movable plate 5 moves upward, it compresses the spring 8. The elastic force of the spring 8 presses the steel pipe through the movable plate 5 to achieve the purpose of buffering.
[0027] In this embodiment, as Figure 4 As shown, the moving plate 5 has a safety block 6 located below the fixed plate 4 on its surface. The safety block 6 prevents the spring 8 from being over-compressed and prevents the spring 8 from being damaged.
[0028] In this embodiment, as Figure 4 As shown, a pressure sensor 18 is provided on the surface of the fixed plate 4. The pressure sensor 18 is located above the safety block 6. When the pressure sensor 18 is in contact with the safety block 6, if the pressure on the pressure sensor 18 is too large, the pressure sensor 18 provides a control signal to the clamping cylinder 3. The clamping cylinder 3 controls the moving plate 5 to move upward to prevent the steel pipe from bending.
[0029] In this embodiment, as Figure 2 As shown, the base 1 has two slide rails 9 on its surface. The inclined plate 10 is slidably connected to the slide rails 9. The slide rails 9 improve the stability and smoothness of the movement of the inclined plate 10, effectively constrain the movement trajectory of the inclined plate 10, and prevent deviation.
[0030] In this embodiment, as Figure 2 As shown, the base 1 has two strip holes 16 on its surface, and the inclined clamp 10 has a movable seat 11 on its side. The movable seat 11 passes through the strip holes 16 and is connected to the synchronizer and the push cylinder 13. The movable seat 11 can be smoothly connected to the connecting rod 14 through the strip holes 16. The strip holes 16 provide sliding space for the movable seat 11.
[0031] In this embodiment, as Figure 1 and Figure 3 As shown, the synchronizer includes a turntable 15 and two connecting rods 14 connected to the turntable 15. The connecting rods 14 are rotatably connected to the moving seat 11. The turntable 15 can make the two connecting rods 14 move synchronously in opposite directions. The movement of the two inclined clamping plates 10 is realized by a push cylinder 13.
[0032] In this embodiment, as Figure 1 As shown, the inclined clamp plate 10 has several sleeves 17 on its side. The insertion shaft of the crescent block 12 is inserted into the sleeve 17, which improves the stability and flexibility of the installation of the crescent block 12. The rotation of the crescent block 12 can better contact the steel pipe.
[0033] Specifically, during use, the steel pipe is placed between the two inclined clamps 10. When the steel pipe presses down on the crescent block 12, the crescent block 12 rotates, and the side of the crescent block 12 with the arc-shaped opening aligns with the steel pipe, which can achieve multi-point support for the steel pipe and provide a large support area for the steel pipe. The pressing cylinder 3 controls the fixed plate 4 and the moving plate 5 to move down. When the moving plate 5 contacts the steel pipe, the pressing cylinder 3 controls the fixed plate 4 to move down, and the top plate compresses the spring 8. The elastic force of the spring 8 is applied to the steel pipe through the moving plate 5, so as to achieve pressing of the steel pipe without over-pressing it.
[0034] When the position of the two inclined clamping plates 10 needs to be adjusted, the cylinder 13 pushes the two moving seats 11 to move horizontally. The moving seats 11 move synchronously through the connecting rod 14 and the turntable 15. The turntable 15 is rotatably connected to the base 1, which can ensure the stability of the movement of the inclined clamping plates 10. By increasing or decreasing the distance of the inclined clamping plates 10, a wider range of steel pipes can be applied, and the compatibility is better.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
