Technical Field
[0001] This utility model relates to the field of elbow processing technology, and in particular to a grinding device for processing elbows of power pipe fittings. Background Technology
[0002] Grinding is an important step in the processing of power pipe elbows. It not only improves the appearance and performance, but also ensures safety, durability and compliance with industry standards. It is a key step in ensuring product quality. The grinding equipment used for processing power pipe elbows is a special device for surface treatment of power pipe elbows.
[0003] Patent CN221774252U discloses a grinding device for processing elbows of power pipe fittings, including a processing table. Placement boxes are fixedly connected to both the front and rear sides of the upper part of the processing table. A handheld grinder is installed inside the placement box located on the front side. A fixing block is fixedly connected to the left side of the upper part of the processing table. An adjusting screw is threadedly connected to the middle of the fixing block. A stabilizing seat is movably connected to the right end of the adjusting screw. A stabilizing groove is formed in the middle of the stabilizing seat. A stabilizing device is provided on the right side of the stabilizing seat. A clamping device is provided on the right side of the upper part of the processing table.
[0004] The aforementioned patent, through its clamping and stabilizing devices, can stably clamp power pipe bends of different sizes, improving the polishing effect. However, the aforementioned device lacks corresponding dust collection equipment. The dust generated during the polishing process will interfere with the contact between the polishing part and the pipe surface, resulting in uneven polishing effect. Furthermore, long-term exposure to the dust environment may cause operators to inhale dust, leading to respiratory diseases, pneumoconiosis, and other occupational diseases, posing a serious threat to their health.
[0005] Therefore, there is a particular need for a grinding device for processing elbows of power pipe fittings to solve the problems existing in the prior art. Utility Model Content
[0006] In order to overcome the shortcomings of existing devices that lack corresponding dust collection equipment, which may lead to uneven grinding results, the technical problem to be solved is to provide a grinding device for processing elbows of power pipe fittings.
[0007] The technical solution is as follows: A grinding device for processing elbows of power pipe fittings includes a processing table, a controller, a filter screen, a collection frame, a vacuum cleaner, electric slide rails, electric sliders, a clamping mechanism, and grinding components. The controller is fixedly connected to the upper right side of the processing table, the filter screen is installed on the upper part of the processing table, the collection frame is fixedly connected to the upper rear side of the processing table, the vacuum cleaner is fixedly connected to the lower front side of the processing table, the vacuum cleaner is electrically connected to the controller, electric slide rails are symmetrically distributed on the upper left and right sides of the processing table, and electric sliders are slidably connected to the sides of the electric slide rails that are close to each other. Both electric sliders are electrically connected to the controller, and clamping mechanisms are provided on the two electric sliders. Grinding components are provided on the front and upper left sides of the upper part of the processing table.
[0008] As a further preferred embodiment, the clamping mechanism includes an electric push rod, a first clamping member, and a second clamping member.

Detailed Implementation
[0022] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.
[0023] Example: A grinding device for processing elbows of power pipe fittings, such as... Figures 1-6As shown, the assembly includes a processing table 1, a controller 2, a filter 3, a collection frame 4, a vacuum cleaner 5, electric slide rails 6, electric sliders 7, a clamping mechanism, and a grinding assembly. The controller 2 is bolted to the upper right side of the processing table 1. The filter 3 is installed on the upper part of the processing table 1. The collection frame 4 is welded to the upper rear side of the processing table 1. The collection frame 4 is higher at the rear and lower at the front, with an inclination angle between 10 and 15 degrees. The outlet of the collection frame 4 is aligned with the upper suction inlet of the vacuum cleaner 5. The vacuum cleaner 5 is bolted to the lower front side of the processing table 1. The vacuum cleaner 5 is electrically connected to the controller 2. Electric slide rails 6 are symmetrically distributed on the upper left and right sides of the processing table 1. Electric sliders 7 are slidably connected to the sides of the electric slide rails 6 that are close to each other. Both electric sliders 7 are electrically connected to the controller 2. A clamping mechanism is provided on both electric sliders 7. Grinding assemblies are provided on the upper front and upper left sides of the processing table 1.
[0024] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the clamping mechanism includes an electric push rod 8, a first clamping member 9, and a second clamping member 10. The electric push rod 8 is bolted to both electric sliders 7. The first clamping member 9 is clamped on the telescopic rod of the electric push rod 8 on the right electric slider 7, and the second clamping member 10 is clamped on the telescopic rod of the electric push rod 8 on the left electric slider 7.
[0025] When this device is needed to grind the front end of an electrical conduit elbow, the operator must first place the collection box directly below the vacuum cleaner 5. Then, the operator can place the electrical conduit elbow to be ground on the first clamping member 9. Next, the operator can start the electric push rod 8 on the left electric slider 7 and the vacuum cleaner 5 by operating the controller 2. The electric push rod 8 will extend, and the electric push rod 8 will drive the second clamping member 10 to move to the right. The first clamping member 9 on the electric push rod 8 extension rod on the upper right side of the processing table 1 and the second clamping member 10 on the electric push rod 8 extension rod on the upper left side of the processing table 1 will move closer to each other, clamping the electrical conduit elbow to be ground, thereby fixing the conduit and ensuring that the conduit will not move during the grinding process.
[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the grinding assembly includes a connecting plate 11, a grinding stone 12, a motor 13, and a grinding component 14. The connecting plate 11 is welded to the rear top of the processing table 1. The grinding stone 12 is glued to the connecting plate 11. The grinding stone 12 is also glued to the front top of the processing table 1. The front top of the processing table 1 is bolted to a motor 13 with its output shaft facing backward, and the rear top of the processing table 1 is bolted to a motor 13 with its output shaft facing right. Both motors 13 are electrically connected to the controller 2. The grinding component 14 is snapped onto the output shaft of both motors 13. The grinding component 14 and the grinding stone 12 are located on the same horizontal line. The area of the grinding component 14 is the same as the pipe opening area of the elbow of the power pipe fitting to be ground.
[0027] Once the elbow of the power pipe fitting to be ground is clamped, the operator can start the two electric sliders 7 and the two motors 13 through the control controller 2. The two electric sliders 7 move along the electric slide rails 6, causing the first clamping member 9 and the second clamping member 10 to move the elbow of the power pipe fitting to be ground forward until the front end of the elbow of the power pipe fitting to be ground contacts the grinding stone 12. The output shaft of the motor 13 then drives the grinding part 14 (e.g., polishing wheel) to start rotating.
[0028] When the front end of the power pipe bend to be ground comes into contact with the grinding stone 12, the operator can control the movement direction of the first clamping member 9 and the second clamping member 10 through the control controller 2, thereby changing the movement trajectory of the power pipe bend to be ground, causing the power pipe bend to move to the left, and thus moving the front end of the power pipe bend on the grinding stone 12, thereby completing the grinding of the front end of the power pipe bend. The finer waste generated by grinding will pass through the filter screen 3 and fall into the collection box below.
[0029] After the power pipe elbow with the front face has been polished and it leaves the polishing stone 12, the operator controls the electric slider 7 through the controller 2. The polished power pipe elbow will be aligned with the polishing part 14 (e.g., polishing wheel). The electric slider 7 will continue to drive the polished power pipe elbow to move to the left. Since the area of the polishing part 14 that is engaged on the top output shaft of the motor 13 is the same as the pipe opening area of the power pipe elbow to be polished, it can fit the pipe opening well to polish the burrs inside the cut, ensuring that the polishing effect is uniform and efficient.
[0030] When it is necessary to grind the other end face of the power pipe bend, the operator can control the movement direction of the first clamping member 9 and the second clamping member 10 by operating the controller 2, so that the power pipe bend moves backward, and then moves the other end face of the power pipe bend on the grinding stone 12, thereby completing the grinding of the other end face of the power pipe bend.
[0031] Similarly, after the power pipe elbow on the other end face is polished and leaves the polishing stone 12, the operator controls the electric slider 7 through the controller 2, and the power pipe elbow on the other end face will be aligned with the polishing part 14 (e.g., polishing wheel) to polish the burrs inside the cut on the other end face.
[0032] If it is necessary to grind electrical conduit elbows of different shapes and sizes, the operator can adjust the electric slider 7 on the electric slide rail 6 through the controller 2 so that it can move to the appropriate position according to the size and shape of the electrical conduit elbow, or replace the first clamping member 9 and the second clamping member 10 according to the shape of the electrical conduit elbow to better clamp the electrical conduit elbow.
[0033] The vacuum cleaner 5 can suck up the debris in the collection box and collect it into the collection box directly below, keeping the working environment clean. The filter screen 3 is installed on the upper part of the processing table 1, which can play a filtering role to prevent larger debris or foreign objects from entering the vacuum cleaner 5 and ensure the normal operation of the vacuum cleaner 5.
[0034] After the grinding of the power pipe elbow is completed, the operator can use the controller 2 to reset the electric push rod 8 on the left electric slider 7, and then remove the ground power pipe elbow. Then, the electrical components can be reset and turned off.
[0035] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
