Description

Technical Field

[0001] This utility model relates to the field of pipe end treatment technology, specifically to a device for deburring PE pipe ends. Background Technology

[0002] Polyethylene (PE) pipes are widely used in water supply and drainage, gas transmission, and agricultural irrigation due to their advantages such as corrosion resistance, flexibility, light weight, and long service life. During the production or on-site cutting of PE pipes, burrs or uneven cuts often occur at the pipe ends. If these burrs are not treated, they can affect the sealing performance of the pipe connections, leading to a risk of leakage.

[0003] Currently, deburring of PE pipe ends is mostly done using manual scrapers, semi-automatic chamfering machines, or simple grinding tools. For large-diameter PE pipes, the end area is large and the pipe wall is relatively flexible. During operation, due to the lack of effective internal support, large-diameter PE pipes are prone to deformation when subjected to external grinding tools, resulting in uneven deburring, excessive cutting in some areas, or incomplete burr removal, which affects processing quality and efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a PE pipe end deburring device to solve the issue that large-diameter PE pipes are prone to deformation at the end when subjected to external grinding tools, thus affecting the deburring effect.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: a PE pipe end deburring device, including a grinding machine body and a processing table, and further including a traction ring, a clamping fastener, a connecting seat, a transmission component, and a connecting plate. The traction ring is fixedly installed inside the processing table. The grinding end of the grinding machine body is correspondingly arranged with the traction ring. The clamping fastener is slidably installed on the surface of the connecting seat, and the clamping fastener and the connecting seat are located inside the traction ring. The moving end at the bottom of the transmission component is connected to the grinding end of the grinding machine body, and the moving end at the top of the transmission component is connected to the connecting plate. The connecting plate and the connecting seat are snap-fitted together.

[0006] The clamping device includes a pressure plate, an adsorption strip, a slide rod, and a first spring. The adsorption strip is embedded inside the pressure plate, the slide rod is fixedly installed on the surface of the connecting seat, the moving end of the slide rod is connected to the pressure plate, one end of the first spring is connected to the pressure plate, and the other end is connected to the fixed end of the slide rod.

[0007] The clamping components are in multiple sets and arranged in a circular array about the connecting seat. The pressure plate is arranged in an arc shape and a certain distance is maintained between the pressure plate and the traction ring.

[0008] The connecting seat includes a fixed post, a slot, a second spring, and an adsorption block. The slot is formed on the rear end surface of the fixed post. One end of the second spring is connected to the interior of the rear end of the fixed post, and the other end is connected to the adsorption block. The adsorption block is slidably installed inside the rear end of the slot.

[0009] The transmission assembly includes a telescopic rod, a lower fixed frame, and an upper fixed frame. The telescopic rod is located on the rear side of the processing table. The lower fixed frame is fixedly installed at the moving end at the bottom of the telescopic rod and is connected to the grinding end of the grinding machine body. The upper fixed frame is fixedly installed at the moving end at the top of the telescopic rod and is connected to the connecting plate.

[0010] The two moving ends of the telescopic rod are connected, with air gaps between them.

[0011] The connecting plate includes a fixed plate, a clamping plate, a third spring, and a traction block. The fixed plate is fixedly installed on the top of the transmission assembly and is located on the rear side of the connecting seat. The clamping plate is rotatably installed inside the fixed plate. One end of the third spring is connected to the clamping plate, and the other end is equipped with a push plate, which is in contact with the inner wall of the fixed plate. The traction block is embedded inside the fixed plate.

[0012] The number of the card plates is multiple, and they are arranged in a circular array about the traction block. The end of the card plate away from the traction block is provided with a hook.

[0013] The beneficial effects of this utility model are as follows: This invention utilizes the electromagnetic attraction of the traction ring to the adsorption strip, causing the pressure plate to apply pressure to the inner wall of the PE pipe end, maintaining its shape and stability. This avoids the problem of slight deformation caused by the inherent flexibility of the PE pipe itself, which can result in over-cutting of the end face or incomplete removal of burrs when a large-diameter PE pipe is placed inside the deburring device due to the lack of internal force and contact between the grinding end and the end. The electromagnetic attraction of the traction block to the adsorption block causes the adsorption block to slide into the fixed plate, pushing the clamping plate to rotate. The clamping plate... The hook is inserted into the slot to achieve quick connection and fixation between the connector and the connector plate. Before the PE pipe is inserted, the weight of the clamp and the connector is supported by the connector plate, which makes it easy to put the PE pipe into the traction ring. This allows the outer wall of the PE pipe to fit against the inner wall of the traction ring, and the inner wall to fit against the outer side of the pressure plate. The horizontal movement of the grinding end of the grinder body is transmitted to the connector plate through the telescopic rod. This causes the grinding end of the grinder body to move forward, which in turn moves the connector plate up away from the rear side of the connector. The grinding end of the grinder body moves backward, which in turn moves the connector plate down to the rear side of the connector, thus avoiding obstruction of the deburring process.

[0016] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0017] Figure 1 - Figure 5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 5 The present invention will be further described below.

[0018] The PE pipe end deburring device includes a grinding machine body 1 and a processing table 2, as well as a traction ring 3, a clamping fastener 4, a connecting seat 5, a transmission component 6, and a connecting plate 7. The traction ring 3 is fixedly installed inside the processing table 2. The grinding end of the grinding machine body 1 is correspondingly set with the traction ring 3. The clamping fastener 4 is slidably installed on the surface of the connecting seat 5, and the clamping fastener 4 and the connecting seat 5 are located inside the traction ring 3. The moving end at the bottom of the transmission component 6 is connected to the grinding end of the grinding machine body 1, and the moving end at the top of the transmission component 6 is connected to the connecting plate 7. The connecting plate 7 and the connecting seat 5 are snap-fitted together. Specifically, the grinding end of the grinding machine body 1 is pushed out to the processing table 2 to deburr the PE pipe port inside the processing table 2. The clamping fastener 4 is electromagnetically attracted by the traction ring 3 to press it tightly against the inner wall of the PE pipe port. The clamping fastener 4 is fixed to the connecting plate 7 by the connecting seat 5. The power of the grinding end of the grinding machine body 1 moving forward is transmitted to the connecting plate 7 by the transmission component 6 to lift it.

[0019] The clamping component 4 includes a pressure plate 401, an adsorption strip 402, a slide bar 403, and a first spring 404. The adsorption strip 402 is embedded inside the pressure plate 401. There are multiple sets of adsorption strips 402, which are arranged at equal intervals inside the adsorption strip 402. The adsorption strip 402 is correspondingly arranged with the traction ring 3. The slide bar 403 is fixedly installed on the surface of the fixed column 501. The moving end of the slide bar 403 is connected to the pressure plate 401. One end of the first spring 404 is connected to the pressure plate 401, and the other end is connected to the fixed end of the slide bar 403. Specifically, the adsorption strip 402 is adsorbed by the traction ring 3, which drives the pressure plate 401 to apply pressure to it along the radial direction of the PE pipe. The pressure inside the PE pipe is used to fasten it to the inside of the traction ring 3. The first spring 404 applies a pulling force to the pressure plate 401, so that when the traction ring 3 does not electromagnetically adsorb the clamp 4, the elastic force of the first spring 404 pulls the pressure plate 401 to maintain the distance between it and the traction ring 3.

[0020] The number of clamping fasteners 4 is multiple, and they are arranged in a circular array about the connecting seat 5. The pressure plate 401 is arranged in an arc shape, and a certain distance is maintained between the pressure plate 401 and the traction ring 3. Specifically, the spacing between multiple sets of pressure plates 401 and the traction ring 3 facilitates workers to quickly place the PE pipe between the traction ring 3 and the pressure plate 401 for deburring.

[0021] The connecting seat 5 includes a fixed post 501, a slot 502, a second spring 503, and an adsorption block 504. The slot 502 is formed on the rear end surface of the fixed post 501 and is correspondingly arranged with the card plate 702. One end of the second spring 503 is connected to the interior of the rear end of the fixed post 501, and the other end is connected to the adsorption block 504. The adsorption block 504 is slidably installed inside the rear end of the slot 502 and is correspondingly arranged with the traction block 704. Specifically, the slot 502 facilitates the quick connection and fixation of the connecting plate 7 and the connecting seat 5, and the second spring 503 pulls the adsorption block 504 to place it inside the rear end of the fixing post 501.

[0022] The transmission assembly 6 includes a telescopic rod 601, a lower fixed frame 602, and an upper fixed frame 603. The telescopic rod 601 is located on the rear side of the processing table 2. The lower fixed frame 602 is fixedly installed on the moving end at the bottom of the telescopic rod 601 and is connected to the grinding end of the grinding machine body 1. The upper fixed frame 603 is fixedly installed on the moving end at the top of the telescopic rod 601 and is connected to the fixed plate 701. Specifically, when the grinding end of the grinding machine body 1 moves horizontally through the lower fixed frame 602, the moving end at the bottom of the telescopic rod 601 moves accordingly, and the moving end at the top of the telescopic rod 601 drives the connecting plate 7 on one side of the upper fixed frame 603 to move up and down.

[0023] The two moving ends of the telescopic rod 601 are connected, with air gaps between them; Specifically, by moving the lower fixed frame 602 forward, the moving end at the bottom of the telescopic rod 601 is driven to slide inside the telescopic rod 601, which compresses the air at the two moving ends of the telescopic rod 601, thereby pushing the moving end at the top of the telescopic rod 601 to move upward, and conversely, driving it to move downward.

[0024] The connecting plate 7 includes a fixed plate 701, a clamping plate 702, a third spring 703, and a traction block 704. The fixed plate 701 is fixedly installed on one side of the upper fixed frame 603 and is located on the rear side of the connecting seat 5. The clamping plate 702 is rotatably installed inside the fixed plate 701. One end of the third spring 703 is connected to the clamping plate 702, and the other end is equipped with a push plate, which is in contact with the inner wall of the fixed plate 701. The traction block 704 is embedded in the interior of the fixed plate 701. Specifically, the traction block 704 electromagnetically attracts the adsorption block 504, causing the adsorption block 504 to slide into the interior of the fixing plate 701 and contact the card plate 702. The card plate 702 rotates and inserts into the card slot 502, thereby realizing the quick connection between the connecting seat 5 and the connecting plate 7. The elastic force of the third spring 703 causes the push plate to contact the inner wall of the fixing plate 701, thereby restoring the card plate 702 to a vertical state.

[0025] The number of card plates 702 is multiple, and they are arranged in a circular array about the traction block 704. The end of the card plate 702 away from the traction block 704 is provided with a hook, which is corresponding to the card slot 502. Specifically, when multiple sets of clamping plates 702 rotate synchronously, their hooks are inserted into the inside of the clamping slot 502 to clamp and fix the fixing post 501.

[0026] In summary: When using this utility model, the operator places the PE pipe to be processed into the traction ring 3, so that the outer wall of the PE pipe is in contact with the inner wall of the traction ring 3, and the inner wall of the PE pipe is in contact with the outer side of the pressure plate 401. After determining the position of the PE pipe, the traction ring 3 is activated to electromagnetically attract the adsorption strip 402, so that the pressure plate 401 overcomes the tension of the first spring 404 and presses tightly against the inner wall of the PE pipe, applying force to fix the PE pipe inside the traction ring 3, ensuring the stability of the shape at the end of the PE pipe. The electromagnetic attraction of the traction block 704 to the adsorption block 504 is released, so that the second spring 503 pulls the adsorption block 504 to slide into the rear end of the fixing post 501, and the adsorption block 504 is released from the fixing post. Inside plate 701, the third spring 703 pushes the clamping plate 702 to rotate and reset to a vertical state, completing the quick disconnection of the connecting seat 5 and the connecting plate 7. This drives the grinding machine body 1 to move its grinding end forward to the PE pipe near the traction ring 3. The lower fixing frame 602 is driven forward by the grinding end of the grinding machine body 1, so that the moving end at the bottom of the telescopic rod 601 is pressed into the telescopic rod 601. The moving end at the top of the telescopic rod 601 is lifted by compressed air, which drives the upper fixing frame 603 and the connecting plate 7 to move upward, so that the connecting plate 7 moves away from the rear of the connecting seat 5, avoiding the connecting plate 7 from obstructing the contact between the grinding end of the grinding machine body 1 and the PE pipe. The grinding machine body 1 is used to deburr the PE pipe. After deburring is completed, the grinding machine body 1 controls its grinding end to move backward. Through the transmission component 6, the connecting plate 7 returns to the rear of the connecting seat 5 of the traction ring 3. The traction block 704 is activated to electromagnetically attract the adsorption block 504, causing the adsorption block 504 to slide into the fixed plate 701 and push the card plate 702 to rotate. The hook of the card plate 702 is inserted into the card slot 502, completing the quick connection between the connecting seat 5 and the connecting plate 7. The electromagnetic attraction between the traction ring 3 and the adsorption strip 402 is released, and the processed PE pipe can be taken out.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
