Description

Technical Field

[0001] This invention relates to the field of pipe fitting processing technology, and in particular to a device for removing burrs from grooved pipe fittings. Background Technology

[0002] Grooved pipe fittings are a new type of steel pipe connection fitting, also called clamp connections. They include both rigid and flexible joints and are widely used in industry and construction. Common grooved pipe fittings are right-angled, but there are also some tee and cross grooved pipe fittings with different shapes. When producing grooved pipe fittings, it is usually necessary to grind them to remove burrs. Since grooved pipe fittings usually have multiple pipe ends, it is necessary to deburr the ribs and pipe ends of the grooved pipe fittings one by one. This requires clamping the pipe fittings multiple times, which greatly reduces the overall processing efficiency and increases the labor intensity of workers.

[0003] An existing invention patent discloses a burr removal device for processing grooved pipe fittings (CN116638399B), which includes a grooved pipe fitting placed on a support mechanism, a clamping mechanism on each first support frame, a first support rod and a second support rod respectively abutting against the clamping mechanism, and a burr removal mechanism on each first support frame; the right-angle curved grooved pipe fitting is placed on the support mechanism, and the burr removal mechanisms on both sides grind it, which can grind the ribs and pipe opening of the grooved pipe fitting from all directions at the same time.

[0004] However, this device can only be used for right-angle curved grooved pipe fittings. It cannot be used for grinding T-junction and cross-junction grooved pipe fittings, which limits its applicability and necessitates the use of additional grinding equipment, increasing costs.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] For the first embodiment, please refer to... Figures 1-4 , Figure 1 This is a schematic diagram of the structure of a grooved pipe fitting burr removal device according to the first embodiment of the present invention; Figure 2 This is a burr removal device for grooved pipe fittings according to the first embodiment of the present invention. Figure 1 A magnified view of detail A; Figure 3 This is a right view of a grooved pipe fitting burr removal device according to the first embodiment of the present invention; Figure 4 This is a rear view of a grooved pipe fitting burr removal device according to the first embodiment of the present invention.

[0024] This invention provides a burr removal device for grooved pipe fittings: including a base 101, a rotary motor 102, a mounting plate 103, multiple clamping components, a grinding motor 104, a grinding disc 105, two grinding brushes 106, a positioning plate 113, a telescopic rod 114, a second spring 115, a first hydraulic rod 116, a transverse sliding seat 117, a micro motor 118, a bidirectional lead screw 119, a micro battery 120, and a support leg 121. The clamping components include a slider 107, a first spring 108, a clamping rod 109, a locking piece 110, a torsion spring 111, and a limiting piece 112.

[0025] The aforementioned solution addresses the problem that existing devices have a limited range of applications and require multiple grinding devices, leading to increased costs. It is understandable that the aforementioned solution can achieve rapid loading and can also effectively clamp pipes of various shapes.

[0026] In this embodiment, the rotary motor 102 is fixed above the base 101; the mounting plate 103 is fixed to the output end of the rotary motor 102; a plurality of clamping members are arranged in a cross shape on the mounting plate 103 for fixing the grooved pipe fitting; the grinding motor 104 is disposed above the base 101; the grinding plate 105 is fixed to the output end of the grinding motor 104; two grinding brushes 106 are symmetrically disposed on the grinding plate 105; the slider 107 is slidably disposed in the mounting plate 103; The first spring 108 is fixedly connected to the slider 107 and to the mounting plate 103; the clamping rod 109 is fixed to the side of the slider 107; the base 101 is the support for the entire device; the rotary motor 102 drives the mounting plate 103 to rotate; multiple clamping members are symmetrically arranged in pairs and in a cross shape on the mounting plate 103 for fixing right-angle bent pipe fittings, cross-shaped pipe fittings, etc., and are installed according to the specific shape of the grooved pipe fitting; the grinding motor 104 is perpendicular to the rotary motor 102. The grinding disc 105 is used to drive the grinding wheel 105 to rotate, thereby rotating the two grinding brushes 106 to grind the grooved pipe fitting from the side. After one outlet end of the grooved pipe fitting is ground, the rotary motor 102 is started and rotated 90 degrees to grind the other side. The slider 107 of the clamping member is used to install the clamping rod 109. The first spring 108 is used to pop out the slider 107. The two symmetrical sliders 107 of the clamping member pop out towards each other, allowing the two clamping rods 109 to clamp the grooved pipe fitting. The cross-shaped arrangement can effectively grind the grooved pipe fitting. Right-angled, cross-shaped, and T-shaped grooved pipe fittings are clamped and then rotated 90 degrees to grind and remove burrs from multiple outlet ends of the grooved pipe fittings. The burr removal device of the present invention can directly squeeze and place the grooved pipe fittings between the clamping rods 109 when placing them. Under the action of the first spring 108, they are automatically clamped, realizing rapid loading. The cross-shaped arrangement can effectively clamp pipe fittings of various shapes, and the rotation grinds each outlet, thereby solving the problem that the existing device has a limited scope of application and requires multiple grinding devices, resulting in increased costs.

[0027] The locking piece 110 is rotatably disposed within the clamping rod 109; the torsion spring 111 is fixedly connected to the locking piece 110 and the clamping rod 109; the limiting piece 112 is disposed on the outside of the clamping rod 109; under the action of the torsion spring 111, the locking piece 110 tends to rotate outward from the clamping rod 109, while the limiting piece 112 is used to block the locking piece 110, ensuring that its maximum rotation angle is perpendicular to the clamping rod 109; the two locking pieces 110 work together to seal the outlet end of the clamping rod 109, preventing the grooved pipe fitting from slipping out during grinding, and during installation, pressing the locking piece 110 inward causes it to rotate and retract into the clamping rod 109, thereby achieving rapid installation of the grooved pipe fitting.

[0028] Secondly, the telescopic rod 114 is fixed in the mounting plate 103; the positioning plate 113 is fixed at the output end of the telescopic rod 114; the second spring 115 is fixedly connected to the mounting plate 103 and the positioning plate 113; the first hydraulic rod 116 is fixed on the base 101; the transverse sliding seat 117 is fixedly connected to the output end of the first hydraulic rod 116 and the grinding motor 104; the telescopic rod 114 is used to install the positioning plate 113, the second spring 115 is used to pop out the positioning plate 113 and press the grooved pipe fitting to the locking piece 110 to achieve positioning of the grooved pipe fitting; and the first hydraulic rod 116 is used to extend and drive the transverse sliding seat 117 to move, adjust the position of the grinding motor 104, and cooperate in grinding the grooved pipe fitting.

[0029] Furthermore, the micro motor 118 is fixed in the grinding disc 105; the bidirectional lead screw 119 is fixedly connected to the output end of the micro motor 118 and threadedly connected to the two grinding brushes 106; the micro battery 120 is connected to the micro motor 118; the micro battery 120 is used to power the micro motor 118. After the micro motor 118 is started, it controls the bidirectional lead screw 119 to rotate, thereby controlling the two grinding brushes 106 to move in opposite directions or in the opposite direction, which is convenient for adjustment according to the diameter of the grooved pipe fitting.

[0030] Finally, the support leg 121 is fixed below the base 101; the support leg 121 is used to support the base 101 and increase its height for easy movement.

[0031] During use, the base 101 serves as the support for the entire device. The rotary motor 102 drives the mounting plate 103 to rotate. Multiple clamping members are symmetrically arranged in pairs and in a cross shape on the mounting plate 103 to fix right-angle bent pipe fittings, cross-shaped pipe fittings, etc., and are installed according to the specific shape of the grooved pipe fitting. The grinding motor 104 is perpendicular to the rotary motor 102 and drives the grinding disc 105 to rotate, thereby rotating the two grinding brushes 106 to grind the grooved pipe fitting from the side. After grinding one outlet end of the grooved pipe fitting, the rotary motor 102 is started and rotated 90 degrees to grind the other side. The slider 1 of the clamping member... 07 is used to install the clamping rod 109. The first spring 108 is used to pop out the slider 107. The two symmetrical sliders 107 of the clamping members pop out towards each other, allowing the two clamping rods 109 to clamp the grooved pipe fitting. The cross-shaped arrangement can effectively clamp right-angled, cross-shaped, and T-shaped grooved pipe fittings. Then, it is rotated 90 degrees to grind and remove burrs from multiple outlet ends of the grooved pipe fitting. The locking piece 110, under the action of the torsion spring 111, has a tendency to rotate outward of the clamping rod 109, while the limiting piece 112 is used to block the locking piece 110, so that its maximum rotation angle is perpendicular to the clamping rod 109. The two locking pieces 110 are used in conjunction. The clamping rod 109 can be closed at its outlet to prevent the grooved pipe from slipping out during grinding. During installation, pressing the locking plate 110 inward causes it to rotate and retract into the clamping rod 109, thus enabling quick installation of the grooved pipe. The telescopic rod 114 is used to install the positioning plate 113, and the second spring 115 is used to eject the positioning plate 113 and press the grooved pipe against the locking plate 110, thus positioning the grooved pipe. The first hydraulic rod 116 extends to move the transverse sliding seat 117, adjusting the position of the grinding motor 104 to assist in grinding the grooved pipe. The micro battery 120 powers the micro motor 118. Powered by the micro motor 118, the micro motor 118 starts and controls the bidirectional lead screw 119 to rotate, thereby controlling the two grinding brushes 106 to move in opposite directions or in the opposite direction, which is convenient for adjustment according to the diameter of the grooved pipe fitting. The support leg 121 is used to support the base 101 and raise its height for easy movement. When placing the grooved pipe fitting, the burr removal device of the present invention can directly squeeze it between the clamping rods 109, and automatically clamp it under the action of the first spring 108, realizing rapid loading. The cross-shaped arrangement can effectively clamp pipe fittings of various shapes, and grind each outlet by rotation, thereby solving the problem that the existing device has a small applicable range and requires multiple grinding devices, resulting in increased costs.
