Description

Technical Field

[0001] This invention relates to the field of bearing housing assembly technology, specifically to a fully automatic bearing housing assembly equipment and method. Background Technology

[0002] A bearing housing is a structure used to support a bearing. Generally, the inner support point of a bearing is the shaft, and the outer support point is the bearing housing. Bearing housings are typically split structures, fastened to the outside of the bearing by two arc-shaped structures and secured with bolts. Some bearing housings are one-piece structures, where the bearing and housing are fixed together by an interference fit.

[0003] When a bearing is press-fitted into its housing, the bearing is typically pressed into the housing using a hydraulic press or similar equipment. However, this process can easily cause scratches on the inner wall of the housing and the outer surface of the bearing due to excessive pressure. Alternatively, the housing can be preheated or the bearing preheated before assembly. Thermal expansion and contraction allow the bearing and housing to return to room temperature, resulting in a press-fitted fit. However, this method requires manual handling and alignment of the bearing or housing, which is cumbersome and reduces assembly efficiency. Further improvements are warranted.

[0012] Preferably, the extrusion fitting includes an upper horizontal arm fixedly installed on the left side of the top of the vertical slide block, a pressure cylinder fixedly installed at the left end of the upper horizontal arm, and an insert cylinder fixedly installed at the bottom end of the pressure cylinder; two vertically distributed partition plates are fixedly installed on the inner wall of the insert cylinder, and an inner support plate is arranged in an array between the two partition plates; a guide window is arrayed through the circumference of the insert cylinder, and the inner support plate is slidably connected to the guide window; a lifting ring is slidably connected inside the pressure cylinder, and multiple clamping plates are fixedly installed at the bottom of the lifting ring; the clamping plates are slidably connected to the partition plates, and the number of clamping plates is twice that of the inner support plate; clamping plates are attached to both sides of each inner support plate; an inclined groove is opened on both sides of the inner support plate; a protruding post is fixedly installed on the surface of the clamping plate, and the protruding post is slidably connected to the inclined groove; a lifting drive component is connected at the center of the lifting ring.

[0013] Preferably, the inner support plate includes a U-shaped cover, with an inclined groove on both sides of the U-shaped cover.

A straight groove, an inclined groove, and a straight groove are formed sequentially from top to bottom on the right side of the arc-shaped plate. The two ends of the inclined groove are connected to the straight groove and the straight groove, respectively. The ball bearing is slidably connected within the straight groove, the inclined groove, and the straight groove.

[0014] A method for assembling a fully automatic bearing housing, the specific operation steps are as follows: S1, the drive shaft is driven to rotate by motor one, and with the transmission action of bevel gear one, bevel gear two and bevel gear three, the lower turntable and the upper turntable rotate in opposite directions, the bearing housing is conveyed to the U-shaped groove one through the feeding channel one, and the bearing is conveyed to the U-shaped groove two through the feeding channel two, so that the bearing housing moves to the top of the clearance opening and the bearing moves to the top of the dropping groove; S2. The first threaded rod is driven to rotate by the second motor, which moves the vertical slide upward, so that the heating coil is inserted into the bearing seat and heats the bearing seat. The sealing plug seals the material drop groove, and the transmission gear is driven to rotate by the rack plate, which drives the second threaded rod to rotate, thereby driving the two baffles to move closer to each other and fit together. The two baffles cover the top of the bearing seat. S3. After the bearing housing is heated, the screw rod is driven by motor two to rotate in the opposite direction, causing the vertical slide to move downward, the pressure cylinder and the insert to move downward, and the ball to slide in the straight groove two. When the inner support plate is inserted into the bearing, the ball slides into the inclined groove two and causes the rotating shaft to rotate relative to the pressure cylinder, driving the lifting ring and the clamping plate to move upward, thereby driving the inner support plate to move outward along the guide window, so that the inner support plate fits against the inner wall of the bearing, and the bearing is stably sleeved on the outside of the insert. S4. The pressure cylinder and insert cylinder continue to move downwards. The ball slides along the straight groove. The bearing moves downwards synchronously with the insert cylinder. When the bearing is in contact with the top of the bearing seat, the bearing slides relative to the insert cylinder. The bottom end of the pressure cylinder is in contact with the top of the bearing and presses the bearing downwards, so that the bearing is pressed into the bearing seat. S5. Then, the vertical slide moves upward, pulling the insert out of the bearing and moving it above the upper turntable. The heating coil is below the support cover, avoiding the rotation paths of the lower and upper turntables. When the assembled bearing seat moves to the left side of the lower turntable, the cylinder output end extends, driving the push plate to move to the left, pushing the bearing seat to the top of the feeding channel, and then transferring the bearing seat to the left through the feeding channel.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a fully automatic bearing housing assembly device and method, which has the following beneficial effects: 1. The fully automatic bearing housing assembly equipment and method transfers the bearing housing and bearing through a bearing housing transfer component and a bearing transfer component, aligning the bearing and bearing housing in the vertical direction. Then, the vertical slide moves upward to insert a heating coil into the bearing housing to heat it. The vertical slide moves downward to move the pressure cylinder and insert cylinder downward, pressing the bearing into the bearing housing through the pressure cylinder. This achieves the purpose of automatically transferring the bearing and bearing housing and high efficiency of interference fit assembly of the bearing and bearing housing. 2. This fully automatic bearing housing assembly equipment and method uses a motor to drive the drive shaft to rotate, which, in conjunction with the transmission action of bevel gears one, two, and three, causes the lower and upper turntables to rotate in opposite directions. The bearing housing is conveyed into U-shaped groove one through feeding channel one, while the bearing is simultaneously conveyed into U-shaped groove two through feeding channel two. This moves the bearing housing above the clearance opening and the bearing above the discharge chute, achieving the purpose of automatically conveying the bearing and bearing housing and aligning the bearing with the bearing housing. 3. The fully automatic bearing housing assembly equipment and method uses a second motor to drive a threaded rod to rotate, which in turn moves the vertical slide upward, allowing the heating coil to be inserted into the bearing housing and heat it. A sealing plug seals the material discharge groove. The rack and pinion drive the transmission gear to rotate, which in turn drives the second threaded rod to rotate, thereby causing two baffles to move closer together and fit together. The two baffles block the top of the bearing housing, thus achieving the purpose of preheating the bearing housing and preventing heat from being conducted to the bearing. 4. This fully automatic bearing housing assembly equipment and method involves a pressure cylinder and insert cylinder moving downwards. A ball bearing slides along a straight groove, and the bearing moves downwards synchronously with the insert cylinder. When the bearing is against the top of the bearing housing, it slides relative to the insert cylinder. The bottom end of the pressure cylinder adheres to the top of the bearing and presses it downwards, forcing the bearing into the bearing housing. A vertical slide moves upwards, pulling the insert cylinder out of the bearing and moving it above the upper turntable. The heating coil is positioned below the support cover, avoiding the rotation paths of the lower and upper turntables. When the assembled bearing housing moves to the left side of the lower turntable, the cylinder output end extends, driving the pusher plate to move to the left, pushing the bearing housing to the top of the unloading channel. The bearing housing is then transferred to the left through the unloading channel. This achieves the purpose of automatically assembling the bearing and bearing housing, and unloading the assembled bearing housing. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-2 A fully automatic bearing housing assembly device includes a lower baffle plate 100, a bearing housing transfer component 200 rotatably connected to the top of the lower baffle plate 100, an upper baffle plate 300 fixedly installed above the lower baffle plate 100, a bearing transfer component 400 rotatably connected to the upper baffle plate 300, and a rotation drive component 500 disposed between the bearing housing transfer component 200 and the bearing transfer component 400; a guide frame 600 is disposed on the right side of the lower baffle plate 100 and the upper baffle plate 300, a vertical slide block 700 is slidably connected to the left side of the guide frame 600, a heating component 800 is fixedly installed at the bottom of the vertical slide block 700, and a pressing and connecting component 900 is fixedly installed at the top of the vertical slide block 700.

[0020] Please see Figure 3The lower retaining plate 100 includes a support cover 101, with a feeding channel 102 on the front side of the support cover 101, a discharging channel 103 on the left side of the support cover 101, and a clearance opening 104 through the bottom right side of the support cover 101. Multiple support columns 105 are fixedly installed on the top of the support cover 101, serving to separate the support cover 101 and the upper retaining plate 300. The bearing housing transfer component 200 includes a lower turntable 201 rotatably connected inside the support cover 101. U-shaped support plates 203 are arrayed through the top edge of the lower turntable 201, and U-shaped support plates 203 are provided at the bottom of a U-shaped groove 202. The width of the U-shaped groove 202 is equal to the outer diameter of the bearing housing, and the U-shaped support plates 203 support the bearing housing. The width of the U-shaped support plates 203 is slightly larger than the inner diameter of the bearing.

[0021] Please see Figure 3 The bearing housing transfer component 200 also includes a pusher plate 204. The pusher plate 204 is horizontal in the middle and vertical at both ends, with the two ends extending in opposite directions. The bottom end of the pusher plate 204 is attached to the top of the lower turntable 201. A straight groove 205 is formed through the middle of the pusher plate 204. A fixing post 206 is fixedly installed at the bottom of the upper baffle 300, and the fixing post 206 is slidably connected within the straight groove 205. A cylinder 207 is fixedly installed at the top of the pusher plate 204, and the cylinder 207 is fixed to the top of the support cover 301. After the bearing and bearing housing are assembled, when the bearing housing moves with the lower turntable 201 to the right end opening of the unloading channel 103, the cylinder 207 drives the pusher plate 204 to move to the left, thus pushing the bearing housing into the unloading channel 103 through the bottom end of the pusher plate 204.

[0022] Please see Figures 4-5 The upper baffle 300 includes a second support cover 301 fixedly installed on the top of the support column 105. A second feeding channel 302 is provided on the rear side of the second support cover 301. Belt conveyors are provided in the first feeding channel 102, the unloading channel 103 and the second feeding channel 302. A drop chute 303 is provided through the bottom right side of the second support cover 301.

[0023] The bearing transfer component 400 includes an upper turntable 401 rotatably connected inside the support cover 301. U-shaped grooves 402 are arrayed through the top edge of the upper turntable 401. The widths of the U-shaped grooves 402 and the discharge chute 303 are equal, and both are equal to the outer diameter of the bearing. The bearing is conveyed into the U-shaped grooves 402 through the feeding channel 302, and in conjunction with the rotation of the upper turntable 401, the bearing moves sequentially to the discharge chute 303.

[0024] Since the width of the discharge chute 303 is equal to the outer diameter of the bearing, when the bearing moves above the discharge chute 303, it is easy for the bearing to fall downwards through the discharge chute 303 under the action of gravity. Therefore, a compression structure needs to be set in the U-shaped groove 402 to simply fix the bearing and prevent it from falling directly through the discharge chute 303. Specifically, an inner liner ring 304 is fixedly installed on the bottom wall of the support 301, and an arc-shaped protrusion 305 is fixedly installed on the outer right side of the inner liner ring 304. The rear end of the arc-shaped protrusion 305 is provided with an inclined surface.

[0025] The bottom of the upper turntable 401 has an annular groove 403, and the inner lining ring 304 and the arc-shaped protrusion 305 are inserted into the annular groove 403. The side of the U-shaped groove 402 has a mounting groove 404 that communicates with the annular groove 403. A pressure plate 405 is slidably connected in the mounting groove 404. A spring 406 is fixedly installed on the side of the pressure plate 405 facing the annular groove 403. A sliding plate 407 is fixedly installed on the end of the spring 406 away from the pressure plate 405. A sliding column 408 is fixedly installed on the side of the sliding plate 407 away from the spring 406. The sliding column 408 is inserted into the annular groove 403.

[0026] When the bearing moves along the second feeding channel 302 into the U-shaped groove 402, the pressure plate 405 is pressed into the mounting groove 404. As the upper turntable 401 rotates clockwise, the sliding column 408 slides along the surface of the inner liner ring 304. When the sliding column 408 slides to the rear end of the arc-shaped protrusion 305, the sliding column 408 gradually moves towards the pressure plate 405, and the spring 406 is compressed and contracted. Through the elasticity of the spring 406, the pressure of the pressure plate 405 on the bearing is increased. This prevents the bearing from falling directly under gravity when it moves above the discharge chute 303.

[0027] Please see Figure 2 and Figure 6 The rotating drive unit 500 includes a motor 501 fixedly installed at the bottom of the support cover 101. A drive shaft 502 is fixedly installed at the output end of the motor 501. The drive shaft 502 is fixedly inserted through the center of the feeding channel 102 and rotatably connected to the center of the upper turntable 401. A bevel gear 503 is fixedly installed at the top of the drive shaft 502. A bevel gear 504 meshes with the right side of the bevel gear 503. A crossbeam 505 is rotatably connected to the right side of the bevel gear 504. The right end of the crossbeam 505 is fixedly installed on the arc plate 915. A bevel gear 506 meshes with the bottom of the bevel gear 504. The bevel gear 506 is fixedly installed at the top center of the upper turntable 401. Through the transmission action of the bevel gears 503, 504, and 506, the lower turntable 201 and the upper turntable 401 rotate in opposite directions.

[0028] Please see Figures 7-8A guide sleeve 601 is fixedly installed on the left side of the guide frame 600, and a guide rail 602 is fixedly installed on the right side of the vertical slide block 700. The guide rail 602 is slidably connected to the guide sleeve 601. A sliding groove 603 is opened through the middle of the guide frame 600, and the sliding groove 603 is set along the length of the guide frame 600. A threaded collar 604 is fixedly installed on the right side of the vertical slide block 700, and the threaded collar 604 is slidably connected in the sliding groove 603. A second motor 605 is set on the right side of the guide frame 600. The output end of the second motor 605 is connected to a first threaded rod 606, and the threaded collar 604 is threadedly connected to the first threaded rod 606.

[0029] Please see Figure 2 and Figures 7-8 The heating assembly 800 includes a lower horizontal arm 801 fixedly installed on the left side of the bottom end of the vertical slide 700. A sealing plug 802 is fixedly installed on the top of the left end of the lower horizontal arm 801. A heating coil 803 is connected to the top of the sealing plug 802. The sealing plug 802 is located directly below the clearance opening 104, and the diameter of the sealing plug 802 is equal to the inner diameter of the clearance opening 104. When the heating coil 803 passes through the clearance opening 104 and is inserted into the bearing housing, the sealing plug 802 seals the clearance opening 104, thereby preventing a large amount of heat from escaping from the clearance opening 104 when the heating coil 803 heats the bearing housing. In practice, the heating coil 803 heats the bearing housing to approximately 150°C.

[0030] L-shaped brackets 804 are fixedly installed on both the front and rear sides of the guide frame 600. A threaded rod 805 is rotatably connected between the left ends of the two L-shaped brackets 804. A transmission gear 806 is fixedly installed in the middle of the threaded rod 805. A rack plate 807 is fixedly installed on the lower left side of the vertical slide 700, and the rack plate 807 meshes with the transmission gear 806. During the upward movement of the vertical slide 700, when the heating coil 803 is inserted into the clearance opening 104, the top of the rack plate 807 contacts and meshes with the transmission gear 806. Afterward, the vertical slide 700 continues to move upward, and the heating coil 803 gradually inserts into the bearing housing. The rack plate 807 drives the transmission gear 806 and the threaded rod 805 to rotate.

[0031] Both the front and rear halves of the threaded rod 805 are threadedly connected to baffle plates 809. Two horizontal slide rails 808 are fixedly installed on the left side of the lower half of the guide frame 600. The two baffle plates 809 are slidably connected to the two horizontal slide rails 808, located between the support cover 101 and the support cover 301. The threads of the front and rear halves of the threaded rod 805 are in opposite directions. Therefore, when the threaded rod 805 rotates, it drives the two baffle plates 809 to move simultaneously towards each other or simultaneously away from each other. When the heating coil 803 is inserted into the bearing housing, the two baffle plates 809 move closer to each other. Specifically, the baffle plates 809 are slightly higher than the top of the lower turntable 201 to prevent them from colliding with the top of the bearing housing during movement. The baffle plates 809 also block the opening at the top of the bearing housing, preventing a large amount of heat from being conducted to the bearing in the U-shaped groove 402.

[0032] Please see Figures 9-12 The extrusion fitting 900 includes an upper horizontal arm 901 fixedly installed on the left side of the top of the vertical slide 700. A pressure cylinder 902 is fixedly installed on the left end of the upper horizontal arm 901, and an insert cylinder 903 is fixedly installed on the bottom end of the pressure cylinder 902. The outer diameter of the insert cylinder 903 is slightly smaller than the inner diameter of the bearing, and the outer diameter of the pressure cylinder 902 is slightly smaller than the outer diameter of the bearing. When the vertical slide 700 moves downward, the insert cylinder 903 can be smoothly inserted into the bearing. When the pressure cylinder 902 is in contact with the top of the bearing, it can push the bearing downward.

[0033] Two vertically distributed partition plates 904 are fixedly installed on the inner wall of the insert 903. An inner support plate 905 is arranged in an array between the two partition plates 904. A guide window 906 is arrayed through the circumference of the insert 903, and the inner support plate 905 is slidably connected to the guide window 906. A lifting ring 907 is slidably connected inside the pressure cylinder 902. Multiple clamping plates 908 are fixedly installed at the bottom of the lifting ring 907. The clamping plates 908 are slidably connected to the partition plates 904. The number of clamping plates 908 is twice that of the inner support plate 905. Each inner support plate 905 has clamping plates 908 attached to both sides. An inclined groove 909 is opened on both sides of the inner support plate 905. A protruding post 910 is fixedly installed on the surface of the clamping plate 908, and the protruding post 910 is slidably connected to the inclined groove 909. The lifting ring 907 moves upward relative to the pressure cylinder 902, causing the protruding column 910 to press against the side wall of the inclined groove 909, which in turn drives the inner support plate 905 to move outward through the guide window 906, thereby fixing the bearing from the inside.

[0034] The inner support plate 905 includes a U-shaped cover 9051, with inclined grooves 909 on both sides of the U-shaped cover 9051. A compression strip 9052 is slidably connected inside the opening of the U-shaped cover 9051, passing through the guide window 906. A spring 9053 is fixedly installed between the compression strip 9052 and the inner wall of the U-shaped cover 9051. Thus, when the protrusion 910 compresses the side wall of the inclined groove 909, causing the U-shaped cover 9051 to move outward through the guide window 906, the compression strip 9052 first presses against the inner wall of the bearing. As the U-shaped cover 9051 continues to move outward, the spring 9053 is compressed, and through the elasticity of the spring 9053, the compression strip 9052 is pressed against the inner wall of the bearing.

[0035] A lifting drive component is connected to the center of the lifting ring 907. The lifting drive component includes a rotating shaft 911 that is rotatably connected through the center of the pressure cylinder 902. A spiral groove 912 is formed on the surface of the rotating shaft 911. The lifting ring 907 is threaded onto the spiral groove 912. A sliding ball 913 is fixedly installed on the circumferential surface of the top end of the rotating shaft 911.

[0036] An arc-shaped plate 915 is attached to the left side of the pressure cylinder 902. A fixing plate 914 is fixedly installed between the arc-shaped plate 915 and the vertical slide block 700. From top to bottom, the right side of the arc-shaped plate 915 has a straight groove 916, an inclined groove 917, and a straight groove 918. The two ends of the inclined groove 917 are connected to the straight groove 916 and the straight groove 918, respectively. A sliding ball 913 is slidably connected in the straight groove 916, the inclined groove 917, and the straight groove 918. When the pressure cylinder 902 and the insert cylinder 903 move downwards, and the bottom end of the inner support plate 905 is not inserted into the bearing, the sliding ball 913 slides in the straight groove 916. After the bottom end of the inner support plate 905 is inserted into the bearing, the sliding ball 913 slides into the inclined groove 917.

[0037] A method for assembling a fully automatic bearing housing, the specific operation steps are as follows: S1, the drive shaft 502 is driven to rotate by the motor 501, and with the transmission action of the bevel gear 503, bevel gear 504 and bevel gear 506, the lower turntable 201 and the upper turntable 401 rotate in opposite directions. The bearing housing is transported to the U-shaped groove 202 through the feeding channel 102, and the bearing is transported to the U-shaped groove 402 through the feeding channel 302, so that the bearing housing moves to the top of the clearance opening 104 and the bearing moves to the top of the dropping groove 303. S2. The second motor 605 drives the first threaded rod 606 to rotate, which drives the vertical slide 700 to move upward, so that the heating coil 803 is inserted into the bearing seat and heats the bearing seat. The sealing plug 802 seals the material discharge groove 303. The rack plate 807 drives the transmission gear 806 to rotate, which drives the second threaded rod 805 to rotate, thereby driving the two baffles 809 to move closer to each other and fit together. The two baffles 809 cover the top of the bearing seat. S3. After the bearing housing is heated, the threaded rod 606 is driven to rotate in the opposite direction by the motor 605, so that the vertical slide 700 moves downward, the pressure cylinder 902 and the insert 903 move downward, and the ball 913 slides in the straight groove 916. After the inner support plate 905 is inserted into the bearing, the ball 913 slides into the inclined groove 917 and makes the rotating shaft 911 rotate relative to the pressure cylinder 902, driving the lifting ring 907 and the clamping plate 908 to move upward, thereby driving the inner support plate 905 to move outward along the guide window 906, so that the inner support plate 905 fits against the inner wall of the bearing, and the bearing is stably sleeved on the outside of the insert 903. S4. The pressure cylinder 902 and the insert cylinder 903 continue to move downwards. The sliding ball 913 slides along the straight groove 918. The bearing moves downwards synchronously with the insert cylinder 903. When the bearing is in contact with the top of the bearing seat, the bearing slides relative to the insert cylinder 903. The bottom end of the pressure cylinder 902 is in contact with the top of the bearing and presses the bearing downwards, so that the bearing is pressed into the bearing seat. S5. Then, the vertical slide 700 moves upward, causing the insert 903 to be pulled out of the bearing and move the insert 903 above the upper turntable 401. The heating coil 803 is below the support cover 101, avoiding the rotation paths of the lower turntable 201 and the upper turntable 401. When the assembled bearing seat moves to the left side of the lower turntable 201, the output end of the cylinder 207 extends, driving the pusher plate 204 to move to the left, pushing the bearing seat to the top of the feeding channel 103, and then transferring the bearing seat to the left through the feeding channel 103.

S2. The second motor (605) drives the first threaded rod (606) to rotate, which drives the vertical slide (700) to move upward, so that the heating coil (803) is inserted into the bearing seat and heats the bearing seat. The sealing plug (802) seals the material drop groove (303), and drives the transmission gear (806) to rotate through the rack plate (807), which drives the second threaded rod (805) to rotate, thereby driving the two baffles (809) to approach each other and stick together.
