Description

Technical Field

[0001] The invention relates to the technical field of roller processing, in particular to a grinding roller top bracket. Background Art

[0002] Traditional grinding roller top brackets are widely used in roller processing to support and position the roller body to ensure the smooth progress of the roller grinding process. Figure 6 Although this structure has certain wear resistance and load-bearing capacity, it still has several significant defects in actual application, which affect the quality of the grinding roller and production efficiency: High static friction causes scratches on the roller surface. There is a large static friction between the hard rubber head and the roller surface. The roller is relatively fixed during roller grinding, which easily causes scratches and surface damage, reducing the surface quality of the workpiece. Single-point support causes roller deformation. Traditional top brackets usually use single-point support, which concentrates the support force, resulting in uneven force on the roller and local deformation, affecting the roller flatness accuracy, and then affecting the stability of subsequent processing and product quality; The processing efficiency is low and the process is complicated. Due to the local deformation of the roller body, an additional arc grinding compensation process is required to correct the error caused by the deformation, which not only prolongs the processing cycle, but also increases the processing difficulty and cost; The service life of the equipment is shortened. Scratches and deformation on the surface of the grinding roller cause the service life of the roller to be significantly shortened, generally by 30%-40%, which increases the equipment maintenance and replacement pressure of the enterprise and affects the economic benefits of production.

[0020] like Figure 1-Figure 5 As shown, a grinding roller top bracket includes a bracket 1, a wheel connector 2 is connected to the bracket 1 through an angle adjustment mechanism 4, a wheel connector 2 5 is connected to the bracket 1 through an angle adjustment mechanism 7, two rubber wheels 1 are rotatably connected to the wheel connector 2, and two rubber wheels 2 6 are rotatably connected to the wheel connector 2 5. The rubber wheels 1 3 and 2 6 are both made of polyurethane composite material, and the Shore hardness of the polyurethane composite material is 70A-80A.

[0021] Example 1: Adjust the angle adjustment mechanism 27 to position the wheel connector 25 to the appropriate position. The roller body is placed on the two rubber wheels 26. The position of the wheel connector 12 is adjusted by the angle adjustment mechanism 14 so that the two rubber wheels 13 and the roller body are in contact. When the machine tool rotates the roller body, the roller body drives the two rubber wheels 13 and 26 to rotate. The friction coefficient between the rubber wheels 13 and 26, which are made of polyurethane composite materials, and the roller body is reduced to below 0.1, which is significantly lower than that of traditional hard rubber plugs (such as Figure 6 As shown) the friction coefficient is 0.6-0.8, which is reduced several times.

[0022] The center line between the two rubber wheels 1 3 and the center line between the two rubber wheels 2 6 form an angle support to form a torque, which reduces the deformation of the roller body by 60%, eliminates the compensating grinding process, and shortens the single-piece processing time by 40%. The number of times the roller body can be reused is increased from the traditional 266 times to 800 times.

[0023] This embodiment has the following beneficial effects: Rubber wheels 1 and 2 are made of polyurethane composite materials, which have good elasticity and wear resistance. The friction coefficient is reduced to below 0.1, which is much lower than the 0.6-0.8 of traditional hard rubber plugs. This effectively reduces scratches on the roller surface and improves the surface quality of the workpiece. The double rubber wheel angle support on the wheel connector 1 2 and the wheel connector 2 5 forms a torque, which significantly reduces the local deformation of the roller body. The deformation of the roller body is reduced by about 60%, improving the flatness accuracy and ensuring the processing quality. The angle adjustment mechanism 1 4 and the angle adjustment mechanism 2 7 equipped in the structure facilitate the adjustment of the rubber wheel position, realize the adaptation to rollers of different specifications, and improve the applicability and flexibility of the equipment; No arc grinding compensation process is required in traditional roller grinding process, and the processing time of single piece is shortened by 40%, which significantly improves production efficiency. Through the above structural improvements, the roller can be reused from the traditional 266 times to more than 800 times, greatly reducing equipment replacement and maintenance costs and enhancing production economic benefits.

The jet mechanism includes a guide rod 19 and a blow tube 20. The guide rod 19 is fixed to the inner wall of the chamber 11. The blow tube 20 is slidably connected to the guide rod 19. The blow tube 20 has a barrel cavity 21. The inner wall of the barrel cavity 21 is slidably connected to a piston assembly 26. The piston assembly 26 is slidably connected to the wedge 14. The blow tube 20 is connected to a diverter head 28 through an accelerating tube 27. The diverter head 28 has two or more diverter channels 29. The two blowing cylinders 20 are fixedly connected by an extension strip 9 . A movable channel 8 is provided on the second wheel connector 5 . The extension strip 9 passes through the movable channel 8 and extends to the outside of the second wheel connector 5 .

[0026] According to an optional embodiment of the present invention, the cylinder cavity 21 is connected to the outer wall of the blowing cylinder 20 through an oil channel 22, the inner wall of the oil channel 22 is connected to a one-way valve 23, the inner wall of the oil channel 22 is slidably connected to a connecting pipe 24, the upper end of the connecting pipe 24 extends above the blowing cylinder 20, and the connecting pipe 24 is connected to the top wall of the blowing cylinder 20 through an elastic element 25. Two oil tanks 16 are fixedly connected to the inner wall of the device cavity 11, and an oil cavity 17 is opened on the oil tank 16. The oil cavity 17 is filled with lubricating oil 18, and the bottom wall of the oil cavity 17 is connected to the bottom wall of the oil tank 16 through an oil channel 2 30, and the inner wall of the oil channel 2 30 is connected to a one-way valve 2 31.

[0027] According to an optional embodiment of the present invention, an extension piece is connected to the connecting pipe 24 , and the extension piece is connected to the top wall of the blowing cylinder 20 through the second elastic element 25 .

[0028] According to an optional embodiment of the present invention, the oil channel 1 22 and the oil channel 2 30 are located on the same vertical axis.

[0029] According to an optional embodiment of the present invention, the lubricating oil 18 is connected to the inner wall of the cavity 11 through a connecting rod.

[0030] According to an optional embodiment of the present invention, the elastic element 15 is a stainless steel spring.

[0031] According to an optional embodiment of the present invention, a cover is movably connected to the oil tank 16 .

[0032] According to an optional embodiment of the present invention, both the one-way valve 1 23 and the one-way valve 2 31 are provided with self-resetting elastic members.

[0033] Example 2: The grinding roller drives the two rubber wheels 26 to rotate, thereby causing one of the rotating shafts 10 to drive the rotating bar 12 to rotate. The balls 13 on the rotating bar 12 continuously push the inclined surface of the top wall of the wedge-shaped piece 14 to move the wedge-shaped piece 14 to the left. Cooperating with the elastic force of the elastic element 15, the wedge-shaped piece 14 drives the two piston assemblies 26 to move back and forth left and right. When the piston assembly 26 moves to the right, air is sucked into the cylinder cavity 21, and when the piston assembly 26 moves to the left, the air is pushed out. Since the inner diameter of the channel of the accelerating tube 27 is small and the inner diameter of the diversion channel 29 is small, the flow rate of the air will increase when it enters the accelerating tube 27 and the diversion channel 29. The air is quickly ejected from multiple diversion channels 29 to the outer wall of the rubber wheel 26, thereby cooling the outer wall of the rubber wheel 26 to prevent the heat generated by the friction between the rubber wheel 26 and the grinding roller from affecting the processing quality of the grinding roller.

[0034] When the rubber wheel 2 6 rotates for too long, the lubricating ability of the lubricating oil between the rubber wheel 2 6 and the rotating shaft 10 decreases, and the friction between the rotating shaft 10 and the rubber wheel 2 6 increases. The extension bar 9 is moved upward, so that the extension bar 9 drives the two air cylinders 20 to move upward, and the diverter head 28 is directed to the connection between the rotating shaft 10 and the rubber wheel 2 6. The upper end of the connecting pipe 24 is inserted into the oil channel 2 30 to push open the one-way valve 2 31, and the connecting pipe 24 is inserted into the oil channel 1 22 to push open the one-way valve 1 23, so that the lubricating oil 18 in the oil chamber 17 is added to the cylinder chamber 21 through the connecting pipe 24. When the piston assembly 26 moves left and right, the lubricating oil 18 in the cylinder chamber 21 will be squeezed out and sprayed to the connection between the rotating shaft 10 and the rubber wheel 2 6 for lubrication, thereby reducing the rotational friction between the rubber wheel 2 6 and the rotating shaft 10, making the rubber wheel 2 6 easier to rotate.

[0035] The extension strip 9 is then moved downward and reset, and the one-way valve 1 23 and the one-way valve 2 31 are reset under the action of the self-resetting elastic member to continue the jetting and prevent the lubricating oil 18 from leaking.

[0036] This embodiment has the following beneficial effects: The rubber wheel 2 6 drives the rotating shaft 10 and the rotating bar 12 to rotate, and the ball 13 pushes the wedge 14 to produce reciprocating motion, driving the piston assembly 26 to inhale and eject air, thereby effectively cooling the outer wall of the rubber wheel 2 6 and preventing the heat generated by friction from affecting the processing quality of the grinding roller; The heat dissipation system accelerates the air jet through the accelerating tube 27 and the diversion channel 29. The multi-channel jet design improves the heat dissipation efficiency, ensuring that the temperature of the rubber wheel 26 and related components remains within a reasonable range during high-intensity operation, thereby extending the service life of the equipment. When the lubricating capacity of the lubricating oil 18 between the second rubber wheel 6 and the rotating shaft 10 decreases, the extension bar 9 drives the air cylinder 20 to move, prompting the connecting pipe 24 to be inserted into the oil channel 1 22 and the second oil channel 30, pushing open the one-way valve 1 23 and the one-way valve 2 31, so that the lubricating oil 18 is automatically replenished to the cylinder cavity 21, ensuring sufficient lubrication between the rotating shaft 10 and the second rubber wheel 6, thereby reducing friction resistance; The combination of automatic lubrication and heat dissipation system effectively reduces mechanical wear and heat between the rotating shaft 10 and the rubber wheel 6, improves the smoothness and stability of the rubber wheel rotation, and reduces maintenance frequency and cost; Through the above mechanism, the overall structure improves the working reliability and processing stability of the grinding roller top bracket, which is conducive to achieving high-quality and high-efficiency grinding roller operations.
