Description

Technical Field

[0001] This utility model relates to the field of metal parts processing technology, and specifically discloses a clamping device for metal parts processing. Background Technology

[0002] Metal parts refer to various components made from metal materials through processing techniques such as casting, forging, cutting, and welding. They are widely used in machinery manufacturing, petrochemicals, construction, transportation, and many other fields. Metal pipe fittings, as an important component of metal parts, possess advantages such as high strength, good rigidity, excellent resistance to high and low temperatures, and long service life, enabling them to meet the demands of complex working conditions. Polishing and grinding the inner and outer walls is one of the crucial processes in the manufacturing of metal pipe fittings.

[0003] In existing technologies, polishing the outer wall of metal pipe fittings often requires fixing both ends of the fitting with a clamping device, and then using a handheld belt sander to polish the outer wall by means of the high-speed movement of the sanding belt. However, after polishing one side of the outer wall of the fitting, it is necessary to disassemble the fitting and re-clamp it to polish the other side, which leads to cumbersome operation and reduced processing efficiency.

[0004] In addition, existing clamping devices have limited functionality. If a clamping device is only suitable for end clamping during outer wall grinding, then a dedicated clamping device must be used for inner wall grinding. This device needs to clamp the outer wall of the pipe fitting to work with power tools such as shank wheel. As a result, one device cannot meet both clamping needs, has poor flexibility, and increases the complexity of process switching.

[0005] Therefore, a clamping device for metal parts processing is needed to solve the above problems. Utility Model Content

[0006] This utility model proposes a clamping device for metal parts processing. When polishing and grinding the outer wall of a pipe, the angle of the pipe can be freely adjusted without repeated clamping. The operation is simple and the work efficiency is effectively improved. The device can simultaneously meet the clamping requirements when grinding the outer wall and the inner wall, which greatly improves the flexibility of use.

[0007] This utility model is implemented as follows: a clamping device for metal parts processing includes a base plate, an upright plate fixedly connected to the upper end of the base plate, an adjustable clamping mechanism on the right side of the upright plate, and a stable clamping mechanism on the left side of the upright plate.

[0008] The adjustable clamping mechanism includes a fixed plate and a connecting plate fixedly connected to the right end of the upright plate. A movable plate is provided between the fixed plate and the connecting plate. A first electric push rod is installed on the upper end of the connecting plate. The output end of the first electric push rod passes through the connecting plate and is fixed with a first pressure sensor between the connecting plate and the movable plate. The opposite ends of the fixed plate and the movable plate are rotatably connected to a rotating shaft through embedded bearings. A conical clamping head is fixedly connected to the opposite ends of the two rotating shafts. The adjustable clamping mechanism also includes a driving mechanism.

[0009] The stable clamping mechanism includes a frame fixedly connected to the left end of the upright plate. A lifting plate is provided inside the frame. A second electric push rod is installed at the upper end of the frame. The output end of the second electric push rod extends into the interior of the frame and is fixedly connected to the lifting plate with a second pressure sensor. V-shaped clamps are embedded in the bottom end of the interior of the frame and the lower end face of the lifting plate.

[0010] As a preferred embodiment of the clamping device for metal parts processing according to this utility model, the driving mechanism includes a driving frame fixedly connected to the upper end of the moving plate, a worm gear rotatably connected inside the driving frame, a worm wheel meshing with the outer wall of the worm gear, a transmission shaft fixedly connected between the worm wheel and the rotating shaft located on the upper side, and a handwheel extending to the outside of the driving frame fixedly connected to the right end of the worm gear.

[0011] As a preferred embodiment of the clamping device for metal parts processing according to this utility model, a controller is installed at the left end of the upright plate, and an operation panel is installed at the left end of the frame.

[0012] As a preferred embodiment of the clamping device for metal parts processing according to this utility model, a slide rail is installed at the right end of the upright plate, and the movable plate is slidably connected to the slide rail.

[0013] As a preferred embodiment of the clamping device for metal parts processing according to this utility model, the left and right ends of the inner wall of the frame are provided with sliding grooves, and the inside of the two sliding grooves is slidably connected with a slider that is fixedly connected to the lifting plate.

[0014] As a preferred clamping device for metal part processing according to the present invention, multiple mounting holes are provided on both the left and right sides of the upper surface of the base plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. When polishing the outer wall of a metal pipe, the moving plate is driven by an electric actuator, which clamps the pipe with two conical clamping heads. The pressure sensor ensures that the clamping force is appropriate. When the angle needs to be adjusted, the drive mechanism drives the rotating shaft and the conical clamping heads to rotate the pipe synchronously. Different parts of the outer wall of the pipe can be polished without disassembling and re-clamping the pipe. The operation is simple and effectively improves work efficiency.

[0017] 2. This device uses a conical clamping head to clamp and fix the pipe from the end for outer wall polishing, and a V-shaped clamping plate to clamp and fix the pipe from the outside for inner wall polishing. It can simultaneously meet the clamping requirements for both outer and inner wall polishing, greatly improving the flexibility of use. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-5 A clamping device for processing metal parts includes a base plate 1, a vertical plate 2 fixedly connected to the upper end of the base plate 1, an adjustable clamping mechanism on the right side of the vertical plate 2, and a stable clamping mechanism on the left side of the vertical plate 2.

[0027] The adjustable clamping mechanism includes a fixed plate 3 and a connecting plate 4 fixedly connected to the right end of the upright plate 2. A movable plate 7 is provided between the fixed plate 3 and the connecting plate 4. A first electric push rod 5 is installed on the upper end of the connecting plate 4. The output end of the first electric push rod 5 passes through the connecting plate 4 and is fixed between the first pressure sensor 6 and the movable plate 7. The opposite ends of the fixed plate 3 and the movable plate 7 are rotatably connected to the rotating shaft 8 through embedded bearings. The opposite ends of the two rotating shafts 8 are fixedly connected to the conical clamping head 9. The adjustable clamping mechanism also includes a drive mechanism.

[0028] The stable clamping mechanism includes a frame 14 fixedly connected to the left end of the upright plate 2. A lifting plate 15 is provided inside the frame 14. A second electric push rod 17 is installed at the upper end of the frame 14. The output end of the second electric push rod 17 extends into the interior of the frame 14 and is fixedly connected to the lifting plate 15 with a second pressure sensor 18. V-shaped clamping plates 16 are embedded in the bottom end of the interior of the frame 14 and the lower end face of the lifting plate 15.

[0029] In this embodiment: when it is necessary to polish the outer wall of the metal pipe, firstly, the lower edge of the inner wall of the pipe to be processed is made to fit against the outer wall of the lower conical clamping head 9. Then, the first electric push rod 5 is activated, and its output end extends downward and pushes the moving plate 7 downward until the outer wall of the upper conical clamping head 9 abuts against the upper edge of the inner wall of the pipe. During this process, the first pressure sensor 6 detects the clamping force on the pipe in real time. When the clamping force of the two conical clamping heads 9 on the pipe just reaches the set threshold, the controller 20 controls the first electric push rod 5 to stop moving, ensuring that the clamping force applied by the conical clamping head 9 to both ends of the pipe is moderate, which avoids the pipe from deforming due to excessive pressure and prevents the pipe from shifting during polishing due to insufficient clamping force, thus achieving the clamping and fixing of the pipe. Moreover, since the two conical clamping heads 9 are conical structures, they can clamp and fix pipes with different inner diameters.

[0030] If the pipe angle needs to be adjusted during the polishing process, the upper rotating shaft 8 is rotated by the drive mechanism. Since the rotating shaft 8 on the fixed plate 3 and the moving plate 7 are connected by embedded bearings, the rotating shaft 8 can drive the conical clamping head 9 and the clamped pipe to rotate synchronously when it rotates, thereby realizing the free adjustment of the pipe angle. This process does not require disassembling the pipe and re-clamping it, and different parts of the outer wall of the pipe can be polished. The operation is simple and effectively improves work efficiency.

[0031] When polishing the inner wall of a metal pipe is required, the operator places the pipe to be processed on the V-shaped clamping plate 16 at the bottom of the frame 14, and then activates the second electric actuator 17. Its output end pushes the lifting plate 15 downward until the V-shaped clamping plate 16 of the lifting plate 15 abuts against the outer wall of the pipe. During this process, the second pressure sensor 18 monitors the clamping force on the pipe in real time. When the pressure of the two V-shaped clamping plates 16 on the pipe reaches the threshold, the second electric actuator 17 stops moving, ensuring that the two V-shaped clamping plates 16... The pressure on the pipe fitting is moderate, which completes the clamping and fixing of the outer wall of the pipe fitting. Since the V-shaped clamp 16 has a V-shaped structure, it can clamp and fix pipe fittings of different diameters. At this time, the operator can use tools such as the handle-mounted flap wheel to penetrate into the inner wall of the pipe fitting and complete the grinding operation in conjunction with this clamping state. The device meets the end clamping requirements when grinding the outer wall through the adjustable clamping mechanism, and achieves the clamping and fixing of the outer wall when grinding the inner wall with the help of the stable clamping mechanism. It can adapt to the clamping requirements of two processing scenarios at the same time, which greatly improves the flexibility of use.

[0032] Both the second electric actuator 17 and the first electric actuator 5 are worm gear type electric actuators, which can prevent the output shaft from moving when clamped.

[0033] As a technical optimization of this utility model, the driving mechanism includes a driving frame 10 fixedly connected to the upper end of the moving plate 7. A worm gear 11 is rotatably connected inside the driving frame 10. A worm wheel 12 is meshed with the outer wall of the worm gear 11. A transmission shaft is fixedly connected between the worm wheel 12 and the rotating shaft 8 located on the upper side. A handwheel 13 extending to the outside of the driving frame 10 is fixedly connected to the right end of the worm gear 11.

[0034] In this embodiment: the operator turns the handwheel 13, which drives the worm 11 in the drive frame 10 to rotate. Since the worm 11 meshes with the worm wheel 12, the worm wheel 12 drives the upper rotating shaft 8 to rotate through the transmission shaft. Since the transmission between the worm 11 and the worm wheel 12 has a self-locking characteristic, it prevents the rotating shaft 8 from rotating on its own.

[0035] As a technical optimization of this utility model, a controller 20 is installed on the left end of the upright plate 2, and an operation panel 19 is installed on the left end of the frame 14.

[0036] In this embodiment: the controller 20 and the operation panel 19 constitute the human-machine interaction and control core. The operation panel 19 receives instructions from the operator and controls the operation of the first electric push rod 5 and the second electric push rod 17 through the controller 20. At the same time, the controller 20 collects data from the first pressure sensor 6 and the second pressure sensor 18 in real time and dynamically adjusts the output force of the first electric push rod 5 and the second electric push rod 17 to ensure that the clamping force is always within the safe threshold.

[0037] As a technical optimization of this utility model, a slide rail is installed on the right end of the upright plate 2, and the movable plate 7 is slidably connected to the slide rail.

[0038] In this embodiment: the slide rail at the right end of the upright plate 2 is slidably connected to the movable plate 7, which provides a guiding effect for the movement of the movable plate 7 and prevents the movable plate 7 from deviating when it moves.

[0039] As a technical optimization of this utility model, the left and right ends of the inner wall of the frame 14 are provided with sliding grooves, and the inside of the two sliding grooves are slidably connected with sliders that are fixedly connected to the lifting plate 15.

[0040] In this embodiment, by setting two slide grooves and two slide rails, a guiding effect is provided for the lifting plate 15, thereby improving the stability of the movement of the lifting plate 15.

[0041] As a technical optimization of this utility model, multiple mounting holes are provided on both the left and right sides of the upper surface of the base plate 1.

[0042] In this embodiment, the device can be installed and fixed by providing multiple mounting holes and using fasteners.

[0043] The working principle and usage process of this utility model are as follows: When it is necessary to polish the outer wall of a metal pipe, firstly, the lower edge of the inner wall of the pipe to be processed is made to fit against the outer wall of the lower conical clamping head 9. Then, the first electric push rod 5 is activated, and its output end extends downward and pushes the moving plate 7 downward until the outer wall of the upper conical clamping head 9 abuts against the upper edge of the inner wall of the pipe. During this process, the first pressure sensor 6 detects the clamping force on the pipe in real time. When the clamping force of the two conical clamping heads 9 on the pipe just reaches the set threshold, the controller 20 controls the first electric push rod 5 to stop moving, ensuring that the clamping force applied by the conical clamping head 9 to both ends of the pipe is moderate, which avoids the pipe from deforming due to excessive pressure and prevents the pipe from shifting during polishing due to insufficient clamping force, thus achieving the clamping and fixing of the pipe. Moreover, since the two conical clamping heads 9 are conical structures, they can clamp and fix pipes with different inner diameters.

[0044] If the pipe angle needs to be adjusted during polishing, the operator turns the handwheel 13, which drives the worm gear 11 inside the drive frame 10 to rotate. Since the worm gear 11 meshes with the worm wheel 12, the worm wheel 12 drives the upper rotating shaft 8 to rotate through the transmission shaft. Since the rotating shaft 8 on the fixed plate 3 and the moving plate 7 are connected by embedded bearings, the rotating shaft 8 can drive the conical clamping head 9 and the clamped pipe to rotate synchronously when it rotates, thereby realizing the free adjustment of the pipe angle. This process does not require disassembling the pipe and re-clamping it, and different parts of the outer wall of the pipe can be polished. The operation is simple and effectively improves work efficiency.

[0045] When polishing the inner wall of a metal pipe is required, the operator places the pipe to be processed on the V-shaped clamping plate 16 at the bottom of the frame 14, and then activates the second electric actuator 17. Its output end pushes the lifting plate 15 downward until the V-shaped clamping plate 16 of the lifting plate 15 abuts against the outer wall of the pipe. During this process, the second pressure sensor 18 monitors the clamping force on the pipe in real time. When the pressure of the two V-shaped clamping plates 16 on the pipe reaches the threshold, the second electric actuator 17 stops moving, ensuring that the two V-shaped clamping plates 16... The pressure on the pipe fitting is moderate, which completes the clamping and fixing of the outer wall of the pipe fitting. Since the V-shaped clamp 16 has a V-shaped structure, it can clamp and fix pipe fittings of different diameters. At this time, the operator can use tools such as the handle-mounted flap wheel to penetrate into the inner wall of the pipe fitting and complete the grinding operation in conjunction with this clamping state. The device meets the end clamping requirements when grinding the outer wall through the adjustable clamping mechanism, and achieves the clamping and fixing of the outer wall when grinding the inner wall with the help of the stable clamping mechanism. It can adapt to the clamping requirements of two processing scenarios at the same time, which greatly improves the flexibility of use.

[0046] Both the second electric actuator 17 and the first electric actuator 5 are worm gear type electric actuators, which can prevent the output shaft from moving when clamped.
