Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe processing technology, specifically to an end face grinding device for processing stainless steel corrugated pipes. Background Technology

[0002] Stainless steel corrugated pipe is a type of piping product used to transport liquids or gases. It is usually made of stainless steel and has a corrugated structure that can withstand certain pressures and temperatures. It is often used in applications such as pipe connections, flexible connections, or vibration absorption.

[0003] Stainless steel corrugated pipes have the advantages of being resistant to oxidation and corrosion. However, after the pipe body is manufactured, its surface contains protrusions and barbs formed during the forming process. In order to carry out normal processing in the future, the end face of the pipe body needs to be ground.

[0004] Currently available stainless steel corrugated pipe end-face grinding devices, while capable of grinding the end faces of corrugated pipes, have the following drawbacks: 1. The grinding heads in these devices have poor adaptability, failing to quickly adapt to corrugated pipes of different outer diameters; 2. The clamping plates that hold the corrugated pipe and maintain stability during grinding only have "two lines" between them and the pipe, resulting in poor stability and a tendency for the pipe to rotate during grinding, hindering the smooth progress of the grinding operation; 3. Fine chips generated during grinding fly everywhere, making subsequent cleaning troublesome and time-consuming. Utility Model Content

[0005] The purpose of this invention is to provide an end face grinding device for processing stainless steel corrugated pipes, which can enhance the adaptability of the grinding head in the grinding device and can quickly adapt to grinding corrugated pipes with different outer diameters, so as to solve the problems mentioned in the background art.

A first bolt is threaded onto the front side of the outer wall of the square tube. The first bolt penetrates a portion of the square tube and abuts against the square rod. A plate is attached to the side of the square tube facing the corrugated pipe. The plate is connected to the square tube by a second bolt. A grinding head is fixed to the surface of the plate away from the square tube. The grinding head is in contact with the corrugated pipe. A rotating rod is fixed to the center of the surface of the circular plate away from the square rod. A sleeve is rotatably connected to the outer wall of the rotating rod. The sleeve is slidably connected to the bottom plate through a groove. A handle is fixed to the top of the sleeve. A motor is fixed to the surface of the sleeve away from the circular plate. The output shaft of the motor is fixedly connected to the rotating rod.

[0007] Preferably, the outer wall of the square rod is provided with graduations.

[0008] Preferably, a pair of protruding rods are fixed to the upper surface of the base plate.

[0009] Preferably, a third bolt is inserted at each of the four corners of the upper surface of the base plate.

[0010] Preferably, the corrugated pipe is provided with a dust collection unit on both ends and the front and rear sides. The dust collection unit includes: multiple vertical plates, which are respectively located on both ends and the front and rear sides of the corrugated pipe. A round tube is fixedly connected to the inner wall of the vertical plate. A folded tube is fixedly sleeved at one end of the round tube. A suction head is fixedly connected to the end of the folded tube away from the round tube. A filter bag is fitted on the outer wall of the round tube.

[0011] Preferably, the clamping plate is provided with a clamping unit on the side facing the corrugated pipe. The clamping unit includes: multiple abutments, each abutment being located on the side of the clamping plate facing the corrugated pipe; an anti-slip strip is fixedly connected to the surface of the abutment away from the clamping plate, the anti-slip strip abutting against the corrugated pipe; an insertion rod is fixedly connected to the surface of the abutment away from the anti-slip strip, the insertion rod being inserted into the clamping plate through a slot; a compression spring is fixedly connected to the end of the insertion rod away from the abutment, and the end of the compression spring away from the insertion rod is fixedly connected to the clamping plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This end-face grinding device for processing stainless steel corrugated pipes has the following advantages over traditional technology:

[0013] Through the cooperation between the base plate, corrugated pipe, linear reciprocating slide rail module, clamping plate and grinding unit, the user first contacts the end of the corrugated pipe 2 to be ground with the grinding head 12, drives the linear reciprocating slide rail module 3 to move the clamping plate 4 towards the corrugated pipe 2, thereby clamping it. At this time, the motor 15 is started and the handle 33 is applied appropriately towards the corrugated pipe 2, and the grinding head 12 can then perform grinding operations on the end of the corrugated pipe 2. Before performing grinding operations, the user can turn the first bolt 9 counterclockwise to separate it from the square rod 7. At this time, the position of the square tube 8 on the outer wall of the square rod 7 can be adjusted so that the grinding head 12 can be adapted to grind corrugated pipes 2 with different outer diameters.

[0014] Through the cooperation between the base plate, corrugated pipe, linear reciprocating slide rail module, clamping plate, grinding unit and chip suction unit, before grinding, the user adjusts the extension length of the folded tube 20, brings the suction head 21 close to the grinding head 12, and then starts the exhaust fan 25 to make the suction head 21 generate suction. This can suck in the fine chips generated during the subsequent grinding operation and collect them into the filter bag 22 for temporary storage, thereby reducing the difficulty of cleaning after grinding.

[0015] Through the cooperation between the base plate, corrugated pipe, linear reciprocating slide rail module, clamping plate and chuck unit, during the process of driving the linear reciprocating slide rail module 3 to bring the clamping plate 4 close to the corrugated pipe 2 and clamp it, the anti-slip strips 31 on the surface of the abutment plate 27 will abut against the outer wall of the corrugated pipe 2. Since there are multiple abutment plates 27 and the adjacent insertion rods 28 are inserted into the slot 29 to different depths, the anti-slip strips 31 on the surface of multiple abutment plates 27 can abut against the outer wall of the corrugated pipe 2, so that the clamping surface of the corrugated pipe 2 forms "multiple lines", thereby enhancing the stability of the corrugated pipe 2 after clamping and facilitating the stable progress of subsequent grinding operations.

[0025] 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.

[0026] Please see Figures 1-7This utility model provides a technical solution: a stainless steel corrugated pipe end face grinding device, including a base plate 1, a corrugated pipe 2 above the base plate 1, linear reciprocating slide rail modules 3 installed on both sides of the upper surface of the base plate 1, a pair of clamping plates 4 installed above the linear reciprocating slide rail modules 3, and grinding units on both sides of the corrugated pipe 2. The grinding units include: a pair of circular plates 5, which are respectively located on both sides of the corrugated pipe 2. A pair of protrusions 6 are fixed to the surface of the circular plates 5 against the corrugated pipe 2. A square rod 7 is fixed between the pair of protrusions 6. A pair of square tubes 8 are fitted on the outer wall of the square rod 7. A first bolt is threaded to the front side of the outer wall of the square tube 8. 9. The first bolt 9 passes through a part of the square tube 8 and abuts against the square rod 7. A plate 10 is attached to the side of the square tube 8 that is close to the corrugated pipe 2. The plate 10 is connected to the square tube 8 by the second bolt 11. A grinding head 12 is fixed to the surface of the plate 10 away from the square tube 8. The grinding head 12 is attached to the corrugated pipe 2. A rotating rod 13 is fixed to the center of the surface of the round plate 5 away from the square rod 7. A sleeve plate 14 is rotatably connected to the outer wall of the rotating rod 13. The sleeve plate 14 is slidably connected to the bottom plate 1 through the sliding groove 32. A handle 33 is fixed to the top of the sleeve plate 14. A motor 15 is fixed to the surface of the sleeve plate 14 away from the round plate 5. The output shaft of the motor 15 is fixedly connected to the rotating rod 13.

[0027] In the specific implementation process, it is worth noting that the bellows 2 is a metal bellows to be ground at the end. The linear reciprocating slide rail module 3 is an important transmission element commonly used in automated equipment to achieve linear reciprocating motion. It is also known as a linear module, linear slide table, or electric cylinder. It is a comprehensive motion system that includes components such as linear guide rails, sliders, and drive systems. It usually consists of two parts: a guide rail and a slider. The guide rail is fixed, and the slider moves linearly along the guide rail. It is an important element that converts rotational motion into linear motion. It consists of a double-ended screw, a nut, and ball bearings. It plays a key transmission role in the linear module, converting the rotational motion of the motor into linear motion to meet various application requirements. The slider in the linear reciprocating slide rail module 3 is fixedly connected to the clamping plate 4, which can control the movement of the clamping plate 4 towards and away from the bellows 2. The center points of the square rod 7, the circular plate 5, and the rotating rod 13 are all located on the same horizontal line. The inner wall of the square cylinder 8 is connected to the square rod 7. The outer wall clearance fit, clearance fit refers to a fit with clearance (including the minimum clearance equal to zero). The second bolt 11 passes through the plate 10 and is threadedly connected to the square tube 8. After the grinding head 12 is severely worn after long-term use, the second bolt 11 can be rotated counterclockwise to separate it from the square tube 8, so that the plate 10 and the grinding head 12 can be replaced. The material of the grinding head 12 is not limited, and it can be any conventional material that can grind metal pipes, including but not limited to corundum sand, silicon carbide and alumina sand, etc. The rotating rod 13 is rotatably connected to the sleeve plate 14 through the bearing. A pair of T-shaped sliders are fixed to the bottom end of the sleeve plate 14. The T-shaped sliders can slide laterally inside the slide groove 32, but cannot be separated from the slide groove 32. The handle 33 is set to facilitate the operator to apply force to the sleeve plate 14. The model of the motor 15 is not limited, as long as it meets the usage requirements. The housing of the motor 15 is fixedly connected to the round plate 5. The power cord of the motor 15 is connected to an external power supply device to provide the required power for the operation of the motor 15.

[0028] Furthermore, the outer wall of the square rod 7 is provided with a scale 16.

[0029] In the specific implementation process, it is worth noting that the setting of scale 16 makes it easier for operators to judge the distance relationship between the two grinding heads 12, and provides certain convenience during the adjustment of the position of the grinding head 12.

[0030] Furthermore, a pair of protruding rods 17 are fixed to the upper surface of the base plate 1.

[0031] In the specific implementation process, it is worth noting that the protruding rod 17 is used to be wound around the longer corrugated pipe 2, which helps the pipe body of the corrugated pipe 2 to remain in a stable state during the grinding process.

[0032] Furthermore, third bolts 18 are inserted into the four corners of the upper surface of the base plate 1.

[0033] In the specific implementation process, it is worth noting that a portion of the third bolt 18 penetrates the base plate 1 and can be used to make a threaded connection with the workbench on which the base plate 1 is installed. This can greatly improve the stability of the base plate 1 on the workbench surface and facilitate the smooth progress of the grinding work.

[0034] Furthermore, the corrugated pipe 2 is provided with a dust suction unit on both ends and the front and rear sides. The dust suction unit includes: multiple vertical plates 19, which are located on both ends and the front and rear sides of the corrugated pipe 2 respectively. A round pipe 26 is fixedly connected to the inner wall of the vertical plate 19. A folded pipe 20 is fixedly sleeved at one end of the round pipe 26. A suction head 21 is fixedly connected to the end of the folded pipe 20 away from the round pipe 26. A filter bag 22 is fitted on the outer wall of the round pipe 26. The filter bag 22 is connected to the round pipe 26 through a pipe clamp 23. A housing 24 is provided on the outer side of the filter bag 22. The housing 24 is threadedly connected to the vertical plate 19. A pair of exhaust fans 25 are fixedly connected to the surface of the housing 24 away from the vertical plate 19.

[0035] In the specific implementation process, it is worth noting that the interior of the round tube 26 is interconnected with the interior of the folded tube 20, the suction head 21, and the filter bag 22. The filter bag 22 is a polyester needle-punched felt filter bag, but other common types of filter bags on the market can also be used, as long as they meet the usage requirements. The air inlet of the exhaust fan 25 is interconnected with the interior of the housing 24. The body of the exhaust fan 25 is fixedly connected to the housing 24. The exhaust port of the exhaust fan 25 is located on the outside of the housing 24. The model of the exhaust fan 25 is not limited, as long as it meets the usage requirements. The power cord of the exhaust fan 25 is connected to an external power supply device to provide the necessary power for the operation of the exhaust fan 25.

[0036] Furthermore, a clamping unit is provided on the side of the clamping plate 4 facing the corrugated pipe 2. The clamping unit includes: multiple abutment plates 27, which are located on the side of the clamping plate 4 facing the corrugated pipe 2 respectively. Anti-slip strips 31 are fixedly connected to the surface of the abutment plate 27 away from the clamping plate 4. The anti-slip strips 31 are pressed against the corrugated pipe 2. A plug rod 28 is fixedly connected to the surface of the abutment plate 27 away from the anti-slip strips 31. The plug rod 28 is connected to the clamping plate 4 through a slot 29. A compression spring 30 is fixedly connected to the end of the plug rod 28 away from the abutment plate 27. The end of the compression spring 30 away from the plug rod 28 is fixedly connected to the clamping plate 4.

[0037] In the specific implementation process, it is worth noting that the anti-slip strip 31 is made of rubber, which has a certain degree of flexibility and a high coefficient of friction. It can generate a large friction force with the contact surface. Moreover, the rubber will undergo elastic deformation when subjected to force, which can better fit the micro-unevenness of the contact surface, thereby increasing the actual contact area and further improving the anti-slip effect. The outer wall of the insertion rod 28 and the inner wall of the slot 29 are fitted with a gap. The elastic coefficient of the compression spring 30 is 5-20 N / CM. The maximum length of the compression spring 30 when not under force will not push the insertion rod 28 out of the slot 29.

[0038] Working principle:

[0039] Preparations before polishing:

[0040] Before grinding, the user can first turn the first bolt 9 counterclockwise to separate it from the square rod 7. At this time, the position of the square tube 8 on the outer wall of the square rod 7 can be adjusted. The grinding head 12 is adapted to the outer diameter of the bellows 2. After determining the position of the grinding head 12, turn the first bolt 9 clockwise to tighten it against the square rod 7 and position the grinding head 12. Then, the user adjusts the extension length of the folded tube 20, brings the suction head 21 close to the grinding head 12, and places the end of the bellows 2 to be ground against the grinding head. When the 12 phases are in contact, the linear reciprocating slide rail module 3 is driven to move the clamping plate 4 toward the bellows 2. The anti-slip strips 31 on the surface of the abutment plate 27 will abut against the outer wall of the bellows 2. Since there are multiple abutment plates 27 and the adjacent insertion rods 28 are inserted into the slot 29 to different depths, the anti-slip strips 31 on the surface of multiple abutment plates 27 can abut against the outer wall of the bellows 2, so that the clamping surface of the bellows 2 forms "multiple lines", thereby enhancing the stability of the bellows 2 after clamping.

[0041] Grinding of bellows:

[0042] Start the exhaust fan 25 to generate suction from the suction head 21. Start the motor 15 to rotate the rotating rod 13, the circular plate 5, and the square rod 7. The two grinding heads 12 rotate around the rotating rod 13. Then, apply appropriate force to the handle 33 towards the bellows 2. The grinding head 12 can then perform grinding operations on the end of the bellows 2. The suction head 21 generates suction, which can suck in the fine debris generated during the grinding operation and collect it inside the filter bag 22 for temporary storage, thereby reducing the difficulty of cleaning after the grinding operation.

[0043] Work to be done after sanding:

[0044] After the end of the last corrugated pipe 2 is polished, drive the linear reciprocating slide rail module 3 to separate the anti-slip strip 31 from the corrugated pipe 2, remove the polished corrugated pipe 2, rotate the housing 24 counterclockwise to separate it from the vertical plate 19, loosen the pipe clamp 23 to remove the filter bag 22, then clean the fine debris collected inside the filter bag 22, and finally reset the cleaned filter bag 22, lock the pipe clamp 23, and reset the housing 24 for use in the next polishing operation.

[0045] 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.
