This method is relatively labor-intensive and inefficient. Moreover, the hammering process can easily cause injuries to workers, generate noise that increases the probability of noise-induced hearing loss among workers, and has a low safety factor. Furthermore, uneven force applied to the bearings during manual hammering can easily lead to bearing damage and render them unusable. Utility Model Content

Detailed Implementation

[0017] The following description provides numerous specific details to offer a more thorough understanding of this application. However, it will be apparent to those skilled in the art that this application can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with this application.

[0018] like Figure 1 and Figure 2 As shown, this application provides a fully automatic pulley bearing press-fitting device 1 for installing bearings 2 into pulleys 3. The fully automatic pulley bearing press-fitting device 1 includes a lower mold mechanism 11 and an upper mold mechanism 12. The lower mold mechanism 11 is used to place the pulley 3, and the upper mold mechanism 12 is used to place the bearing 2. The upper mold mechanism 12 and the lower mold mechanism 11 work together to ensure that the bearing 2 can be accurately installed into the pulley 3. The overall dimensions of the fully automatic pulley bearing press-fitting device 1 are 1800mm × 1300mm × 605mm, with a concave slot in the center serving as the operating position, the opening size being 800mm × 800mm. The fully automatic pulley bearing press-fitting device 1 is painted primarily in a blue tone, which is less likely to cause visual fatigue and provides high working speed and accuracy. The overall design of the fully automatic pulley bearing press-fitting device 1 conforms to ergonomic design.

[0019] The lower mold mechanism 11 is used to house the pulley 3. The pulley 3 is tightly fitted to the lower mold mechanism 11. The inner circumferential surface of the lower mold mechanism 11 is used to fit against the outer circumferential surface 31 of the pulley 3. Thus, the lower mold mechanism 11 can position the pulley 3. The lower mold mechanism 11 is located below the upper mold mechanism 12. The upper mold mechanism 12 enables the bearing 2 to be accurately installed inside the pulley 3 and ensures the coaxiality of the bearing 2 and the pulley 3.

[0020] The upper mold mechanism 12 includes a force-applying member 121 and a shaft member 122, with the shaft member 122 connected to the force-applying member 121. The force-applying member 121 and the shaft member 122 are integrally formed. The force-applying member 121 and the shaft member 122 are coaxially arranged. The shaft member 122 protrudes from the lower surface of the force-applying member 121 toward the lower mold mechanism 11. The shaft member 122 is used to pass through the bearing 2. The shaft member 122 is coaxially arranged with the bearing 2. The shaft member 122 passes through the bearing hole 21. The central axis of the shaft member 122 is parallel to the central axis of the bearing 2. Preferably, the central axis of the shaft member 122 coincides with the central axis of the bearing 2. This allows the force exerted by the force-applying member 121 on the bearing 2 to be uniformly applied to the bearing 2.

[0021] The force-applying component 121 can move toward the lower mold mechanism 11, and can also move toward the lower mold mechanism 11 along the axial direction of the shaft component 122. The force-applying component 121 is located above the lower mold mechanism 11 along the height direction of the fully automatic pulley bearing press-fitting equipment 1. The force-applying component 121 can also move downward along the height direction of the fully automatic pulley bearing press-fitting equipment 1.

[0022] The force-applying component 121 can drive the shaft component 122 to move. The force-applying component 121 can drive the shaft component 122 to move towards the lower mold mechanism 11. The shaft component 122 moves towards the lower mold mechanism 11 to drive the bearing 2 to move towards the pulley 3. The shaft component 122 drives the bearing 2 to move into the pulley 3. The outer peripheral surface 22 of the bearing 2 and the inner peripheral surface 32 of the pulley 3 (the inner peripheral surface 32 of the pulley 3 is...) Figure 4 (As shown in the image) They are tightly fitted together. This ensures that the bearing 2 and the pulley 3 are tightly fitted together, allowing the operator to accurately grasp the force on the bearing 2, avoiding excessive stroke during pressing, thus preventing deformation or even damage to the bearing 2 or pulley 3, and also avoiding insufficient stroke causing improper assembly.

[0023] Combination Figure 4 As shown, the force-applying component 121 includes a force-applying lower surface 1211, which applies a force to the bearing 2, pressing it into the pulley 3. The force-applying lower surface 1211 applies a force to the bearing 2 towards the lower mold mechanism 11. The force-applying lower surface 1211 is in close contact with the bearing 2. Preferably, the force-applying lower surface 1211 is in close contact with the upper surface of the bearing 2. The force-applying lower surface 1211 applies a force to the bearing 2, thereby pressing the bearing 2 into the interior of the pulley 3. The shaft component 122 is coaxially arranged with the bearing 2. Therefore, the force applied by the force-applying lower surface 1211 to the bearing 2 can be uniformly applied to the bearing 2.

[0024] like Figure 3 As shown, two bearings 2 can be fitted onto the shaft member 122. The force applied by the force-applying member 121 to one bearing 2 can be transmitted to the other bearing 2. The shaft member 122 and the two bearings 2 are coaxially arranged. This ensures the coaxiality of the shaft member 122 and the two bearings 2, and avoids the two bearings 2 from shifting and being unable to be assembled into the pulley 3.

[0025] The fully automatic pulley bearing press-fitting equipment 1 according to this application is used to install bearing 2 into pulley 3. The fully automatic pulley bearing press-fitting equipment 1 includes a lower mold mechanism 11 and an upper mold mechanism 12. The lower mold mechanism 11 is used to place the pulley 3. The inner circumferential surface of the lower mold mechanism 11 is used to fit against the outer circumferential surface 31 of the pulley 3. The upper mold mechanism 12 includes a force-applying member 121 and a shaft member 122. The force-applying member 121 is movable toward the lower mold mechanism 11. The force-applying member 121 includes a force-applying lower surface 1211. The shaft member 122 protrudes from the lower surface of the force-applying member 121 toward the lower mold mechanism 11. The shaft member 122 is coaxially arranged with the lower mold mechanism 11. The shaft member 122 is used to pass through the bearing 2. The shaft member 122 moves toward the lower mold mechanism 11 to drive the bearing 2 to move into the pulley 3. The force-applying lower surface 1211 applies a force to press the bearing 2 into the pulley 3. In this way, the fully automatic pulley bearing press-fitting equipment 1 can press the bearing 2 into the pulley 3, realize fully automatic rotation and press-fitting, reduce manual labor, increase work efficiency, prevent personnel injury, reduce labor intensity, and during the press-fitting process, the shaft component 122 and the lower mold mechanism 11 are coaxially set, so that the bearing 2 is subjected to uniform force, avoiding damage to the bearing 2 due to uneven force application.

[0026] Furthermore, such as Figure 2 and Figure 4 As shown, the lower mold mechanism 11 includes a lower mold platform component 111, which is used to house the pulley 3. The lower mold platform component 111 has a roughly circular cross-sectional shape. The cross-section of the lower mold platform component 111 is parallel to the axial direction of the shaft component 122. The pulley 3 is coaxially arranged with the lower mold platform component 111. The central axis of the pulley 3 coincides with the central axis of the lower mold platform component 111. The lower mold platform component 111 is located below the upper mold mechanism 12. The lower mold platform component 111 is coaxially arranged with the upper mold mechanism 12. The lower mold platform component 111 is coaxially arranged with the shaft component 122.

[0027] The lower mold platform component 111 includes a lower mold upper surface 112, on which a groove 113 is provided. The groove 113 is recessed from the lower mold upper surface 112 in a direction away from the upper mold mechanism 12. A pulley 3 is arranged in the groove 113, and the inner circumferential surface 114 of the groove 113 is used to fit against the outer circumferential surface 31 of the pulley 3. The groove 113 is coaxial with the pulley 3. The groove 113 is coaxial with the shaft component 122. Thus, the pulley 3 and the shaft component 122 are coaxially arranged.

[0028] The lower mold mechanism 11 also includes a lower mold base component 115, which is located below the lower mold platform component 111. The lower mold base component 115 supports the lower mold platform component 111. The lower mold base component 115 is connected to the lower mold platform component 111. Preferably, the lower mold base component 115 and the lower mold platform component 111 are integrally formed. The dimension of the lower mold base component 115 in the radial direction of the pulley 3 is smaller than that of the lower mold platform component 111. This reduces material usage and decreases the weight of the lower mold mechanism 11.

[0029] Furthermore, the lower mold base component 115 is also provided with a weight-reducing hole 116, which can reduce the weight of the lower mold base component 115, thereby reducing the weight of the lower mold mechanism 11. Preferably, the weight-reducing hole 116 opens outward along the axial direction of the lower mold base component 115. This facilitates processing. The weight-reducing hole 116 can be constructed as an annular shape. The weight-reducing hole 116 is coaxially arranged with the lower mold table component 111. This avoids uneven force distribution and subsequent tipping when the force-applying component 121 applies force to the pulley 3.

[0030] The fully automatic pulley bearing press-fitting equipment 1 also includes a support mechanism 13, which supports the lower mold mechanism 11. The support mechanism 13 is fixed together with the lower mold mechanism 11. The lower mold mechanism 11 is connected to the support mechanism 13 by welding. The support mechanism 13 is located below the lower mold mechanism 11. The support mechanism 13 can rotate, thereby driving the lower mold mechanism 11 to rotate. The axial direction of the support mechanism 13 is parallel to the axial direction of the lower mold mechanism 11. The support mechanism 13 includes a supporting upper surface 131, which supports the lower mold mechanism 11. The support mechanism 13 is constructed as a turntable. The cross-sectional shape of the supporting upper surface 131 is approximately circular. The cross-section of the supporting upper surface 131 is perpendicular to the axial direction of the shaft member 122. The diameter of the turntable is 430 mm.

[0031] The support mechanism 13 includes a limiting member 132, which protrudes from the upper support surface 131 toward the upper mold mechanism 12. The limiting member 132 restricts the movement of the lower mold mechanism 11. The lower mold mechanism 11 is disposed within the limiting member 132. The inner peripheral surface of the limiting member 132 is in close contact with the outer peripheral surface of the lower mold mechanism 11. Preferably, the inner peripheral surface of the limiting member 132 is in close contact with the outer peripheral surface of the lower mold base member 115. This prevents the lower mold mechanism 11 from moving.

[0032] As an embodiment of this disclosure, the fully automatic pulley bearing press-fitting equipment 1 includes a lower mold mechanism 11, which is coaxially arranged with an upper mold mechanism 12. The central axis of the lower mold mechanism 11 coincides with the central axis of the support mechanism 13, and the central axis of the support mechanism 13 coincides with the central axis of the upper mold mechanism 12. The lower mold mechanism 11 is located at the center of the support mechanism 13. The central axis of the shaft member 122 coincides with the central axis of the support mechanism 13. This ensures that the shaft member 122 can drive the bearing 2 to accurately enter the pulley 3.

[0033] In one embodiment of this disclosure, the central axis of the support mechanism 13 is spaced apart from the central axis of the lower mold mechanism 11, and the central axis of the support mechanism 13 is spaced apart from the central axis of the upper mold mechanism 12. The fully automatic pulley bearing pressing equipment 1 includes at least two lower mold mechanisms 11, which are spaced apart along the circumferential direction of the support mechanism 13. The at least two lower mold mechanisms 11 are used to hold at least two pulleys 3 respectively.

[0034] The support mechanism 13 is rotatable in its circumferential direction, thereby driving at least two lower mold mechanisms 11 to rotate. The at least two lower mold mechanisms 11 rotate in the circumferential direction of the support mechanism 13, thereby driving at least two pulleys 3 to rotate. The rotation of the support mechanism 13 drives at least two lower mold mechanisms 11 to rotate in the circumferential direction of the support mechanism 13, so that they respectively move below the upper mold mechanism 12, such that at least two pulleys 3 are respectively located below the upper mold mechanism 12.

[0035] For example, the fully automatic pulley bearing press-fitting equipment 1 includes a first lower mold mechanism, a second lower mold mechanism, a third lower mold mechanism, and a fourth lower mold mechanism, which are arranged at intervals along the circumferential direction of the support mechanism 13. The first lower mold mechanism is used to place the first pulley. The second lower mold mechanism is used to place the second pulley. The third lower mold mechanism is used to place the third pulley. The fourth lower mold mechanism is used to place the fourth pulley. The support mechanism 13 supports the first lower mold mechanism, the second lower mold mechanism, the third lower mold mechanism, and the fourth lower mold mechanism. Rotation of the support mechanism 13 can drive the first lower mold mechanism, the second lower mold mechanism, the third lower mold mechanism, and the fourth lower mold mechanism to rotate. The first lower mold mechanism, the second lower mold mechanism, the third lower mold mechanism, and the fourth lower mold mechanism can all rotate along the circumferential direction of the support mechanism 13. The first lower mold mechanism, the second lower mold mechanism, the third lower mold mechanism, and the fourth lower mold mechanism can all rotate to a position below the upper mold mechanism 12.

[0036] To enable the support mechanism 13 to rotate, the fully automatic pulley bearing press-fitting equipment 1 includes a drive mechanism 14 connected to the support mechanism 13 to drive the support mechanism 13 to rotate circumferentially. The drive mechanism 14 is constructed as a stepper motor, thereby adjusting the rotation angle and speed of the support mechanism 13 according to the position and number of the lower mold mechanism 11. Preferably, the drive mechanism 14 can be constructed as a geared stepper motor with adjustable step angle. The geared stepper motor adopts an INSTA 85mm planetary geared stepper motor, model YSD288-KA8-PB5, with a reduction ratio of 1:5. The driver model is SEA2M68, the driving voltage is DC12V-80V (optimal input voltage DC60V), and the internal bipolar constant current chopper method is used.

[0037] The fully automatic pulley bearing press-fitting equipment 1 also includes a pressing mechanism 15, which is connected to the upper mold mechanism 12. The pressing mechanism 15 can drive the force-applying component 121 to move towards the lower mold mechanism 11. The pressing mechanism 15 can be constructed as a pneumatic press. The pneumatic press can drive the force-applying component 121 to move. Preferably, the pneumatic press has a body size of 480mm × 240mm × 680mm, a model number of PLE-14-100-10-M, an input voltage of AC220 / 50, a pressure of 0.8T-1.4T, a cylinder diameter of 160mm, a stroke of 100mm, and an adjustable stroke of 10mm. The handle and the shaft component 122 are connected by a spline, allowing for adjustment at any angle. The pneumatic press also has an anti-rotation function for the main shaft (i.e., the shaft component 122) during the pressing process. The pneumatic press also uses an integrated ductile iron rectangular guide rail, which has good mechanical rigidity, toughness, and wear resistance, and can withstand large pressure and impact.

[0038] The pressing mechanism 15 may include a pressure end 152, which is movable along the axial direction of the shaft member 122. Preferably, the pressure end 152 is telescopically movable along the axial direction of the shaft member 122. The pressure end 152 is connected to the upper mold mechanism 12.

[0039] More specifically, the pressing mechanism 15 includes a receiving cavity 151, in which a force-applying member 121 is disposed. The receiving cavity 151 opens toward the upper mold mechanism 12. The force-applying member 121 is located in and connected to the receiving cavity 151. The force-applying member 121 can be connected to the receiving cavity 151 via a connector. The connector can be a bolt, screw, etc. Further, the pressure end 152 may include the receiving cavity 151, which is connected to the force-applying member 121. The pressure end 152 can drive the force-applying member 121 to move along the axial direction of the shaft member 122.

[0040] Preferably, the fully automatic pulley bearing press-fitting equipment 1 also includes a protective mechanism to improve safety. The protective mechanism can be constructed as a protective cover. The protective cover is located outside the turntable to prevent workers from being scratched or injured during the turntable's operation.

[0041] The turntable is equipped with a sensor limit device, which is controlled by a PLC system. The next action will only begin after the pressing action is completely completed, reducing the risk of injury from human error.

[0042] To more precisely control the rotation of the support mechanism 13, combined with Figure 5 As shown, the fully automatic pulley bearing press-fitting equipment 1 also includes a control mechanism, which is communicatively connected to the drive mechanism 14. Preferably, the control mechanism includes a PLC (Programmable Logic Controller), which controls the operation of the drive mechanism 14. The control mechanism uses a Siemens PLC S7-200 CPU224XP as the main control unit, providing running commands to the stepper motor driver. The PLC program can control the origin limit, stamping limit, automatic start, automatic stop, automatic reset, jogging forward rotation, and electric reverse rotation of the support mechanism 13, and can also control the up and down movement of the cylinder of the pneumatic press, and realize protection functions such as stamping operation, running indication, and stamping warning.

[0043] The fully automatic pulley bearing press-fitting equipment 1 also includes a storage mechanism for storing workpieces. The storage mechanism is located to the side of the support mechanism 13. The fully automatic pulley bearing press-fitting equipment 1 includes two storage mechanisms for storing unfinished and finished products, respectively.

[0044] The fully automatic pulley bearing press-fitting equipment 1 is controlled by a PLC. After each 90° rotation, it precisely positions and stops. The pneumatic press completes the pressing, and the upper die mechanism 12 resets before proceeding to the next operation. Specifically, the drive mechanism 14 drives the support mechanism 13 to stop at specific points and times during rotation. The operator places the pulley 3 into the lower die mechanism 11 and sequentially places the bearing 2 onto the shaft component 122. The support mechanism 13 rotates to the press-fitting point for automatic assembly. The PLC uses an adjustable step angle to allow the workpiece to stop at a set position. The stepper motor pauses for a few seconds at a 90° step angle setting, and the PLC controls the lower pressing mechanism 15 to press down. The lower pressing mechanism 15 drives the upper die mechanism 12 downwards to complete the press-fitting. After press-fitting, the workpiece rotates 180° and is removed by the operator. After the upper die mechanism 12 resets, the next operation begins.
