Description

Technical Field

[0001] The invention relates to the technical field of motor end cover processing, and more specifically, to a comprehensive machine for bearing pressing and gluing of motor end covers. Background Art

[0002] The motor end cover is a key component of the motor, used to fix and support the motor shaft, protect the internal components, and play a role in sealing and dustproofing. It is usually made of cast iron, cast steel or aluminum alloy, with good strength and wear resistance. Pressing the bearing and gluing are important steps in the motor assembly process. Pressing the bearing firmly installs the bearing into the bearing chamber of the motor end cover to ensure the stable operation of the motor. The gluing of the motor end cover is to ensure the sealing between the end cover and the motor to prevent dust and moisture from entering the motor.

[0003] The current operation method of pressing bearings and applying glue on the motor end cover is: first place the motor end cover on the table, then grab the bearing and press it into the bearing chamber in the middle of the motor end cover, and at the same time apply sealant to the outer ring of the motor end cover. In order to enhance the strength of the end cover and prevent lubricating oil leakage, before pressing the bearing in, a glue spinner will be used to evenly throw the glue into the bearing chamber, and then the bearing will be pressed in accurately.

[0004] However, since the glue is first applied to the inside of the bearing chamber and the direction in which the bearing enters the motor end cover is limited, during the process of the motor end cover pressing the bearing, the glue is easily squeezed and pushed into the bearing chamber, and then accumulated at the end position of the bearing chamber. This method will cause the glue to squeeze into the bearing ball position, affecting the normal operation of the bearing. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a comprehensive machine for pressing bearings and gluing end covers of motors.

[0007] A first gluing assembly is installed on the top of the workbench, and the first gluing assembly includes a supporting frame installed on the top of the workbench and a servo motor installed on the bottom of the supporting frame, the output end of the servo motor is connected to a swing arm, a gluing motor is installed at the bottom of one end of the swing arm, the output end of the gluing motor is connected to a cylinder, a ring body is connected to the outer side wall of the cylinder, and a plurality of gluing holes are equidistantly opened on the outer wall of the cylinder and above the ring body.

[0008] A grabbing assembly and a material pressing assembly are arranged on one side of the workbench, and a second gluing assembly and a cleaning assembly are arranged on the top of the placement table and on one side of the end cover.

[0009] The present invention is further configured as follows: the grabbing assembly is located between the pressing assembly and the workbench, the grabbing assembly includes two legs arranged on one side of the workbench, a first electric slide rail is installed on the top of the two legs, a second electric slide rail is slidably connected to one side of the first electric slide rail, a telescopic cylinder is slidably connected to one side of the second electric slide rail, and a clamping cylinder is installed on the end of the piston rod of the telescopic cylinder.

[0010] By adopting the above technical solution, the servo motor drives the swing arm to swing, so that the cylinder fits the outer wall of the bearing, and the glue flows out through the glue coating hole and is evenly coated on the outer wall of the bearing. The glue coating motor drives the cylinder to rotate slowly to ensure that the glue is evenly rolled. After the glue coating is completed, the grabbing component moves the bearing to the top of the end cover and places it, and then the pressing component presses the bearing into the end cover. This bearing pressing method can ensure that the glue will not flow and accumulate inside the end cover.

[0011] The telescopic cylinder and the clamping cylinder can be moved to an external placement rack to grab the bearing. After the bearing is grabbed, the first electric slide rail and the second electric slide rail are used to move the bearing to the top of the end cover. Then, the telescopic cylinder drives the clamping cylinder and the bearing to move directly above the bearing chamber of the end cover. Then, the second electric slide rail is used to control the bearing to move downward. Then, the clamping cylinder releases and resets the bearing. Then, the bearing can be pressed into the bearing chamber of the end cover through the pressing assembly.

[0012] The present invention is further configured as follows: the pressing assembly includes a stand arranged on the side of the first electric slide rail away from the workbench and a bracket installed on the side wall of the stand, a lifting cylinder is vertically installed on the top of the bracket, the bottom end of the piston rod of the lifting cylinder is connected to a moving frame, and a pressing rod is vertically installed on the bottom of the moving frame.

[0014] By adopting the above technical solution, the lifting cylinder drives the movable frame and the pressure rod to move up and down. Before the bearing is placed on the top of the end cover, the glue is first thrown onto the wall of the bearing chamber of the end cover by an external glue-spinning machine, and then the bearing is placed. After the placement is completed, the lifting cylinder is used to drive the movable frame and the pressure rod to move downward, and then the bearing can be pressed into the bearing chamber on the end cover. The adjustment frame can rotate on the outer wall of the fixed rod, and then the angle of the adjustment frame can be adjusted, so that the glue removal head can be opposite to the outer wall of the end cover, and then the glue coating cylinder is used to drive the positioning frame and the glue removal head to move , and then the glue discharge head is fitted to the position where glue is required on the outer wall of the end cover, and then the adjustment frame is fixed with a locking screw. After the adjustment is completed, the external glue supply equipment discharges the glue using the glue discharge head, and at the same time the electric turntable can drive the end cover to rotate, thereby facilitating the gluing of the end cover, and during the rotating gluing process, the bearing can be pressed into the end cover at the same time, that is, the pressure rod is fitted with the top of the inner ring of the bearing, so that when the end cover rotates, the end cover and the outer ring of the bearing are squeezed against each other and rotate synchronously, so that the bearing is pressed into the interior of the end cover without affecting the rotation of the end cover.

[0015] The present invention is further configured as follows: the cleaning component includes a third electric slide rail installed on the top of the placing table and a fourth electric slide rail slidably connected to the top of the third electric slide rail, the fourth electric slide rail is vertically arranged, and an L-shaped plate is slidably connected to the side wall of the fourth electric slide rail, a cleaning motor is installed on the top of the L-shaped plate, the output end of the cleaning motor passes through the L-shaped plate and is connected to a rotating plate, two auxiliary motors are installed on the top of the rotating plate, and a glue scraping mechanism and a glue cleaning mechanism are arranged at the bottom of the rotating plate, and the glue scraping mechanism and the glue cleaning mechanism are arranged corresponding to the two auxiliary motors.

[0016] The present invention is further configured as follows: the scraping mechanism includes a mounting seat installed at one end of the bottom of the rotating plate, the bottom of the mounting seat is rotatably connected to a plate body, one of the auxiliary motors is connected to the plate body, and four U-shaped scrapers are connected around the bottom of the plate body.

[0017] The present invention is further configured as follows: an inclined portion is provided on the inner wall of each of the U-shaped scrapers, and a stopper is provided on the side wall of the U-shaped scraper.

[0018] The present invention is further configured as follows: the U-shaped scraper is hollow, and a plurality of through holes are equidistantly provided on the inclined portion.

[0019] The present invention is further configured as follows: the glue cleaning mechanism includes a cross installed at the bottom of the rotating plate and away from one end of the glue scraping mechanism, four swing rods are swingably connected to the side walls of the cross, and cleaning blocks are provided at the ends of the four swing rods.

[0020] The present invention is further configured as follows: a worm gear is rotatably connected to the side wall of the cross and the position corresponding to the rocker arm, the worm gear is connected to the corresponding rocker arm, a glue cleaning cylinder is hingedly installed on the side wall of each rocker arm, the piston rod end of the glue cleaning cylinder is hinged to the corresponding cleaning block, and the cleaning block is hinged to the bottom end of the corresponding rocker arm, a driving space is opened in the middle of the cross, the four crosses extend into the driving space, the interior of the driving space is rotatably connected to a worm, the worm is connected to the output end of the corresponding auxiliary motor, and the worm is meshed with four worm gears.

[0021] By adopting the above technical solution, when the scraper mechanism cleans the glue on the bearing surface, the U-shaped scraper fits the bearing surface, and the auxiliary motor drives the plate body to rotate, so that the scraper scrapes on the bearing surface, and the scraper opening faces the rotation direction. The inclined part scrapes up the glue and collects it inside the scraper. When the glue accumulates on the inclined part, it flows into the scraper through the through hole and is collected, ensuring that the overflowed glue will not contaminate the bearing.

[0022] When the end cap needs to be cleaned, the cleaning motor drives the rotating plate to rotate, so that the scraping mechanism and the cleaning mechanism are displaced alternately, and the cleaning mechanism is moved above the end cap. Then, the electric slide rail drives the L-shaped plate and related components to move downward, so that the cleaning mechanism goes deep into the end cap bearing chamber, and the cleaning block spacing is adjusted to fit the inner wall of the end cap. When the end cap rotates, the cleaning block rubs against the inner wall to scrape off the glue. By adjusting the cleaning block spacing multiple times, the glue removal needs of the stepped side wall of the end cap bearing chamber can be met.

[0023] By setting a glue cleaning cylinder, the glue cleaning cylinder pushes the cleaning block to swing, and the cleaning block is adjusted to an inclined state, which is convenient for removing glue from the fillet position inside the end cover bearing chamber. The cleaning block continues to swing to a vertical state, which is convenient for removing glue from the bottom wall position inside the end cover bearing chamber. This design meets the glue removal needs of end covers of different sizes, fillets and sections.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: (1) By setting the cylinder, the servo motor drives the swing arm to swing, so that the cylinder fits the outer wall of the bearing, and the glue flows out through the glue coating hole and is evenly coated on the outer wall of the bearing. The glue coating motor drives the cylinder to rotate slowly to ensure that the glue is evenly rolled. After the glue coating is completed, the grabbing component moves the bearing to the top of the end cover and places it. Then the pressing component presses the bearing into the end cover. The bearing and the end cover squeeze the glue, and the glue flows outward along the outer ring of the bearing. This bearing pressing method can ensure that the glue will not flow and accumulate inside the end cover.

[0025] (2) By setting a U-shaped scraper, when the scraper mechanism cleans the glue on the bearing surface, the U-shaped scraper fits the bearing surface, and the auxiliary motor drives the plate body to rotate, so that the scraper scrapes on the bearing surface. The scraper opening faces the direction of rotation, and the inclined part scrapes up the glue and collects it inside the scraper. When the glue accumulates on the inclined part, it flows into the scraper through the through hole and is collected inside the scraper, ensuring that the overflowed glue will not contaminate the bearing.

[0026] (3) When the end cover needs to be cleaned, the cleaning motor drives the rotating plate to rotate, so that the scraping mechanism and the cleaning mechanism are displaced alternately, and the cleaning mechanism is moved to the top of the end cover. Then, the electric slide rail drives the L-shaped plate and related components to move downward, so that the cleaning mechanism goes deep into the end cover bearing chamber, and the cleaning block spacing is adjusted to fit the inner wall of the end cover. When the end cover rotates, the cleaning block rubs against the inner wall to scrape off the glue. By adjusting the cleaning block spacing multiple times, the glue removal requirements of the stepped side wall of the end cover bearing chamber can be met.

[0027] (4) By setting a glue cleaning cylinder, the glue cleaning cylinder pushes the cleaning block to swing, and the cleaning block is adjusted to an inclined state, which is convenient for removing glue from the fillet position inside the end cover bearing chamber. The cleaning block continues to swing to a vertical state, which is convenient for removing glue from the bottom wall position inside the end cover bearing chamber. This design meets the glue removal needs of end covers of different sizes, fillets and sections. BRIEF DESCRIPTION OF THE DRAWINGS

After the bearing is grabbed, the first electric slide rail 22 and the second electric slide rail 23 are used to cooperate to move the bearing to the top of the end cover 7. Then, the telescopic cylinder 24 drives the clamping cylinder 25 and the bearing to move directly above the bearing chamber of the end cover 7. Then, the second electric slide rail 23 is used to control the bearing to move downward. Then, the clamping cylinder 25 releases and resets the bearing. Then, the bearing can be pressed into the bearing chamber of the end cover 7 through the pressing assembly 3.

[0043] See also Figure 2 The specific structure of the pressing component 3 is as follows: The pressing assembly 3 includes a stand 31 arranged on the side of the first electric slide rail 22 away from the workbench 11 and a bracket 32 ​​installed on the side wall of the stand 31. A lifting cylinder 33 is vertically installed on the top of the bracket 32. The bottom end of the piston rod of the lifting cylinder 33 is connected to a moving frame 34. A pressing rod 35 is vertically installed on the bottom of the moving frame 34. The stand 31 and the bracket 32 ​​form a main frame. The lifting cylinder 33 is used to drive the moving frame 34 and the pressing rod 35 to move up and down. Before the bearing is placed on the top of the end cover 7, the glue is first thrown onto the inner wall of the bearing chamber of the end cover 7 through an external glue throwing machine, and then the bearing is placed. After the placement is completed, the lifting cylinder 33 is used to drive the moving frame 34 and the pressing rod 35 to move downward, so that the bearing can be pressed into the bearing chamber on the end cover 7.

[0044] See also Figure 1 and Figure 6 A second glue coating component 5 is provided on the top of the placement table 12 and on one side of the end cover 7. The second glue coating component 5 is used to apply sealant to the outer wall of the end cover 7, so as to improve the sealing performance when the end cover 7 is connected to the motor housing. The specific structure of the second glue coating component 5 is as follows: See also Figure 1 and Figure 6 The second glue coating assembly 5 includes a vertical plate 51 installed on one side of the top of the placement table 12, the side wall of the vertical plate 51 is connected to a fixing rod 52, the outer side wall of the fixing rod 52 is installed with an adjusting frame 53, the side wall of the adjusting frame 53 is installed with a glue coating cylinder 54, the piston rod end of the glue coating cylinder 54 is connected with a positioning frame 55, and a glue discharge head 56 is installed on the side of the positioning frame 55 away from the glue coating cylinder 54. The adjusting frame 53 can rotate on the outer wall of the fixing rod 52, thereby adjusting the angle of the adjusting frame 53, so that the glue discharge head 56 can be opposite to the outer wall of the end cover 7, and then the positioning frame 55 and the glue discharge head are driven by the glue coating cylinder 54. 56 moves, so that the glue discharge head 56 is attached to the position where the outer wall of the end cover 7 needs to be glued, and then the adjustment frame 53 is fixed with a locking screw. After the adjustment is completed, the external glue supply equipment discharges the glue with the glue discharge head 56, and the electric turntable 13 can drive the end cover 7 to rotate, so as to facilitate the gluing of the end cover 7, and in the process of rotating gluing, the bearing can be pressed into the end cover 7 at the same time, that is, the pressure rod 35 is attached to the top of the inner ring of the bearing, so that when the end cover 7 rotates, the end cover 7 and the outer ring of the bearing are squeezed against each other and rotate synchronously, so that the bearing is pressed into the interior of the end cover 7 without affecting the rotation of the end cover 7.

[0045] In the second embodiment, since the glue is first applied to the inside of the bearing chamber, and the direction in which the bearing enters the end cover 7 is limited, during the process of the end cover 7 pressing the bearing, the glue is easily squeezed and pushed into the bearing chamber, and then accumulated at the end position of the bearing chamber. This method will cause the glue to squeeze into the bearing ball position, affecting the normal operation of the bearing.

[0046] To this end, a first glue coating component 4 is installed on the top of the workbench 11. The first glue coating component 4 is used to apply glue on the outer wall of the bearing, while the end cover 7 bearing chamber is not coated with glue, that is, when the glue-coated bearing is pressed into the end cover 7 bearing chamber, the glue is squeezed to flow to the outside of the end cover 7, and does not flow to the inside of the end cover 7, so as to avoid the glue accumulating at the end position of the bearing chamber to pollute the bearing. The specific structure of the first glue coating component 4 is as follows: See also Figure 3-Figure 5 The first glue coating component 4 includes a carrier frame 41 installed on the top of the workbench 11 and a servo motor 47 installed on the bottom of the carrier frame 41. The output end of the servo motor 47 is connected to a swing arm 42. A glue coating motor 43 is installed at the bottom of one end of the swing arm 42. The output end of the glue coating motor 43 is connected to a cylinder 44. A ring body 45 is connected to the outer wall of the cylinder 44. A plurality of glue coating holes 46 are equidistantly provided on the outer wall of the cylinder 44 and above the ring body 45. When the clamping cylinder 25 clamps the bearing and moves it to the position of the first glue coating component 4, the outer ring of the bearing fits on the ring body 45. The ring body 45 is used to perform the function of preliminary positioning of the bearing. The servo motor 47 is connected to the output end of the servo motor 47. The motor 47 is used to drive the swing arm 42 to swing, so that the cylinder 44 can fit on the outer wall of the bearing. The glue supply hose of the external glue supply device is connected to the cylinder 44, that is, the external glue supply device supplies glue into the cylinder 44 through the glue supply hose, and then the glue flows out through the glue coating hole 46, so that the glue is coated on the outer wall of the bearing, and then the glue coating motor 43 is used to drive the cylinder 44 to rotate slowly, so that the cylinder 44 rolls the glue onto the outer wall of the bearing. After the bearing is coated with glue, the grabbing component 2 moves the bearing to the top of the end cover 7 and places it there. Then, the bearing is pressed into the interior of the end cover 7 through the pressing component 3. This bearing pressing method can ensure that the glue will not flow and accumulate inside the end cover 7.

[0047] However, the method of applying glue on the outer wall of the bearing and then pressing the bearing into the bearing chamber will still cause the glue to be squeezed out from the end of the bearing away from the bearing chamber, resulting in glue overflow.

[0048] For this purpose, see Figure 1 A cleaning assembly 6 is provided on the top of the placement table 12 and on one side of the end cover 7. The cleaning assembly 6 is used to clean the glue overflowing from the end of the bearing away from the bearing chamber. The specific structure of the cleaning assembly 6 is as follows: See also Figure 7-Figure 9The cleaning assembly 6 includes a third electric slide rail 61 installed on the top of the placement table 12 and a fourth electric slide rail 62 slidably connected to the top of the third electric slide rail 61. The fourth electric slide rail 62 is vertically arranged. An L-shaped plate 63 is slidably connected to the side wall of the fourth electric slide rail 62. A cleaning motor 64 is installed on the top of the L-shaped plate 63. The output end of the cleaning motor 64 passes through the L-shaped plate 63 and is connected to a rotating plate 65. Two auxiliary motors 66 are installed on the top of the rotating plate 65. A scraping mechanism 67 is arranged at the bottom of the rotating plate 65. The scraping mechanism 67 and one of the auxiliary motors 66 are connected. Correspondingly, the third electric slide rail 61 is used to drive the fourth electric slide rail 62 to move horizontally, and the fourth electric slide rail 62 is used to drive the L-shaped plate 63 to move up and down, thereby adjusting the displacement of the cleaning motor 64, the rotating plate 65 and the scraping mechanism 67. That is, when the bearing pressing operation is completed, the third electric slide rail 61 and the fourth electric slide rail 62 cooperate to move the scraping mechanism 67 to the top of the bearing, and make the scraping mechanism 67 fit on the top of the bearing. The scraping mechanism 67 is used to clean the glue overflowing from the end of the bearing away from the bearing chamber. The specific structure of the scraping mechanism 67 is as follows: See also Figure 8 and Fig. 9 The scraper mechanism 67 includes a mounting seat 671 mounted on one end of the bottom of the rotating plate 65, the bottom of the mounting seat 671 is rotatably connected to a plate body 672, one of the auxiliary motors 66 is connected to the plate body 672, and the bottom of the plate body 672 is surrounded by four U-shaped scrapers 673, each of which has an inclined portion 674 on its inner wall, and a stopper is provided on the side wall of the U-shaped scraper 673. The U-shaped scraper 673 is hollow, and a plurality of through holes 675 are equidistantly provided on the inclined portion 674. When the scraper mechanism 67 cleans the glue on the bearing surface, first The U-shaped scraper 673 is attached to the bearing surface, and then the corresponding auxiliary motor 66 is used to drive the plate body 672 to rotate. The plate body 672 drives the four U-shaped scrapers 673 to scrape the bearing surface. The opening direction of the U-shaped scraper 673 is set in the direction of rotation. The inclined portion 674 set on the U-shaped scraper 673 scrapes up the glue, and the glue is retained inside the U-shaped scraper 673. When the glue accumulates at the position of the inclined portion 674, the glue flows through the through hole 675 to the inside of the U-shaped scraper 673 for collection, thereby ensuring that the overflowed glue will not contaminate the bearing.

[0049] In the third embodiment, when the bearing inside the end cover 7 is damaged, the bearing needs to be disassembled and replaced. At this time, there will be solidified glue inside the end cover 7, and the glue needs to be processed before the new bearing can be installed. The conventional cleaning method is to manually scrape off the internal glue, or directly use a glue removal brush to grind it. However, the interior of the end cover 7 is stepped, has rounded corners, and is of different sizes. The conventional glue removal brush cannot adapt to the size, and the side wall can be cleaned, but the end face cannot be cleaned.

[0050] See also Figure 7 and Fig.10 For this purpose, a glue cleaning mechanism 68 is provided at the bottom of the rotating plate 65. The glue cleaning mechanism 68 is provided corresponding to another auxiliary motor 66. The glue cleaning mechanism 68 is used to clean the glue remaining inside the end cover 7 to be repaired, so that the new bearing can be installed inside the end cover 7. The specific structure of the glue cleaning mechanism 68 is as follows: See also Fig.10 The glue cleaning mechanism 68 includes a cross 681 installed at the bottom of the rotating plate 65 and away from one end of the scraping mechanism 67. Four swing rods 684 are swingably connected to the side wall of the cross 681. The ends of the four swing rods 684 are hinged with cleaning blocks 685. The side wall of the cross 681 is rotatably connected to the position corresponding to the swing rod 684. The worm gear 683 is connected to the corresponding swing rod 684. A driving space is opened in the middle of the cross 681. The four crosses 681 extend into the driving space. A worm 682 is internally connected for rotation, and the worm 682 is connected to the output end of the corresponding auxiliary motor 66. The worm 682 is meshed with four worm wheels 683. The auxiliary motor 66 corresponding to the glue cleaning mechanism 68 is used to drive the worm 682 to rotate. When the worm 682 rotates, it drives the corresponding four worm wheels 683 to rotate. The worm wheel 683 drives the corresponding rocker rod 684 and the cleaning block 685 to swing, so that the distance between the four cleaning blocks 685 can be adjusted to adapt to the needs of glue cleaning of the inner wall with different diameters in the stepped position inside the end cover 7.

[0051] Specifically, when the end cover 7 needs to be cleaned of glue, the cleaning motor 64 drives the rotating plate 65 to rotate, and the rotating plate 65 drives the glue scraping mechanism 67 and the glue cleaning mechanism 68 to be alternately displaced, so that the glue cleaning mechanism 68 moves to the top of the end cover 7, and then the fourth electric slide rail 62 drives the L-shaped plate 63, the cleaning motor 64, the rotating plate 65, the glue scraping mechanism 67 and the glue cleaning mechanism 68 to move downward, so that the glue cleaning mechanism 68 penetrates into the bearing chamber of the end cover 7, and then the spacing between the four cleaning blocks 685 is adjusted, so that the cleaning blocks 685 are attached to the inner wall position of the bearing chamber of the end cover 7, and then the end cover 7 rotates, and the cleaning blocks 685 rub against the inner wall of the bearing chamber of the end cover 7, so that the glue is scraped off, and through multiple spacing adjustments of the cleaning blocks 685, the step-shaped position of the side wall of the bearing chamber of the end cover 7 is met for glue removal.

[0052] See also Fig.10, a glue cleaning cylinder 686 is hingedly installed on the side wall of each swing rod 684, and the piston rod end of the glue cleaning cylinder 686 is hinged to the corresponding cleaning block 685. After the glue removal of the side wall of the bearing chamber of the end cover 7 is completed, the glue cleaning cylinder 686 is used to push the corresponding cleaning block 685 to swing, and the cleaning block 685 is adjusted to a tilted state. In this state, it is convenient for the cleaning block 685 to remove glue from the fillet position inside the bearing chamber of the end cover 7. When the cleaning block 685 continues to swing, it is in a vertical state. In this state, it is convenient for the cleaning block 685 to remove glue from the bottom wall position inside the bearing chamber of the end cover 7, meeting the glue removal requirements of the end cover 7 with different sizes, fillets and sections.

[0053] After the glue removal is completed, the end cover 7 can be used to press the bearing glue by the cooperation of the grabbing component 2, the pressing component 3, the first glue coating component 4, the second glue coating component 5 and the cleaning component 6.

[0054] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
