Description

Technical Field

[0001] This utility model belongs to the field of mechanical assembly technology, and in particular relates to a bearing press-fitting device. Background Technology

[0002] Currently, bearing bushes are critical moving parts in large mechanical equipment such as engines and compressors, and their press-fit quality directly affects the reliability, stability, and service life of the entire equipment. Bearing bushes typically need to be precisely pressed into the housing mounting holes or bearing seats. Existing technology uses floating C-shaped press-fit arms to press the housing and bearing bushes. However, during the press-fitting process, the C-shaped press-fit arms can easily apply excessive force to the housing, causing damage. Furthermore, the bearing bushes are in a floating state during the press-fitting process, leading to lower press-fitting accuracy.

[0003] To solve the above-mentioned technical problems, this utility model designs a bearing press-fitting device. Utility Model Content

[0004] This utility model provides a bearing press-fitting device, which aims to solve the problems of excessive stress on the housing and low press-fitting accuracy during the press-fitting process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing bush pressing device, comprising a frame, a storage tray, a transfer mechanism, a floating mechanism, and a pressing mechanism. The transfer mechanism is used to move the bearing bush from the storage tray to the floating mechanism. The floating mechanism includes a top rod assembly and a floating sleeve assembly. The floating sleeve assembly is sleeved on the top rod assembly, and a bearing bush placement position is formed between the floating sleeve assembly and the top rod assembly. The floating sleeve assembly can float up and down relative to the top rod assembly. The top rod assembly can drive the bearing bush to rise and fall relative to the frame. The pressing mechanism includes a press and a floating platform. The press is located above the floating platform. The floating platform can float up and down relative to the frame. The floating platform holds a housing of the bearing bush to be installed. The housing has bearing bush mounting holes. The floating mechanism can move below the floating platform so that the bearing bush corresponds to the bearing bush mounting holes.

[0006] Based on the above technical solution, the top rod assembly includes a base, a top rod, and a drive rod. The top rod passes through the base, and a limiting part is provided at the top of the top rod to support the bearing. The drive rod is located below the top rod and can drive the top rod to rise and fall relative to the base.

[0007] Furthermore, the frame is provided with a first guide rail and a first driving member, and the base is disposed on the first guide rail. The first driving member can drive the base to move along the first guide rail toward or away from the location below the floating platform mounting position.

[0008] Furthermore, the top rod assembly also includes a support plate and a telescopic rod. The support plate is disposed above the base and is fixedly sleeved on the top rod. The telescopic rod passes through the base, with its top end fixed to the support plate and its bottom end fixed to the frame. When the drive rod drives the top rod to rise and fall, the telescopic rod causes the support plate to rise and fall relative to the base.

[0009] Based on the above technical solution, the floating sleeve assembly includes a floating sleeve and an elastic element. The floating sleeve is circumferentially sleeved on the top of the top rod. The floating sleeve, the limiting part, and the outer side wall of the top rod form a bearing placement position. One end of the elastic element abuts against the floating sleeve, and the other end of the elastic element abuts against the support plate. The floating sleeve can float up and down relative to the bearing under the action of the elastic element.

[0010] Furthermore, the floating platform includes a tooling plate and multiple elastic support legs. The tooling plate is supported on the frame by the multiple elastic support legs. The tooling plate is provided with clearance holes and multiple positioning pins.

[0011] Based on the above technical solution, the bearing press-fitting equipment also includes a clamping and adjusting mechanism. The clamping and adjusting mechanism includes a clamping table and a rotary drive motor. The rotary drive motor can drive the clamping table to rotate. The transfer mechanism includes a first moving mechanism. The first moving mechanism includes a three-axis drive component and a first clamping component disposed on the three-axis drive component. The first clamping component can move along the XYZ axis direction to move the bearing from the storage tray to the clamping table.

[0012] Furthermore, the bearing press-fitting equipment also includes a detection sensor, which is positioned opposite to the bearing clamped by the clamping table to detect the position of the characteristic hole of the bearing.

[0013] Based on the above technical solution, the transfer mechanism further includes a second moving mechanism, which includes an X-axis drive member, a Z-axis drive member disposed on the X-axis drive member, and a second clamping member disposed on the Z-axis drive member. The second clamping member can move along the X-axis and Z-axis directions to move the bearing from the clamping table to the floating mechanism.

[0014] Furthermore, the Z-axis drive component is provided with a fixed plate, the second clamping component is fixed to the fixed plate, the fixed plate is also provided with two Z-axis drive cylinders, the two Z-axis drive cylinders are located on both sides of the second clamping component, and the ends of the two Z-axis drive cylinders are provided with pressure plates, the pressure plates can be raised and lowered relative to the second clamping component under the drive of the two Z-axis drive cylinders.

[0015] Compared with related technologies, the beneficial effects of this utility model are as follows: This invention utilizes a storage tray to store bearing bushes to be installed. A transfer mechanism moves the bearing bushes from the storage tray to a floating mechanism, placing them in the bearing bush placement position between the floating sleeve assembly and the push rod assembly. The floating mechanism then moves below the floating platform, aligning the bearing bush with its mounting hole. The push rod assembly lifts the bearing bush to near the mounting hole. A press above the floating platform simultaneously presses down on the housing and the floating platform, bringing the edge of the mounting hole into contact with the floating sleeve assembly. The floating sleeve assembly then sinks relative to the push rod assembly, gradually pressing the bearing bush into the mounting hole. After installation, the press returns to its original position, and the floating platform floats back to its initial position. The floating platform mitigates and releases some of the force exerted by the press during the housing pressing process, preventing excessive force on the housing and avoiding damage to its upper surface. During the pressing process, the upper press presses down on the housing while the lower push rod assembly moves upward and remains stationary. This unidirectional pressing force from the upper part facilitates control of the entire pressing process and improves pressing accuracy. Attached Figure Description

[0022] Combination Figure 1-2 As shown in the figure, this disclosure provides a bearing bush pressing device, including a frame 1, a storage tray 2, a transfer mechanism 3, a floating mechanism 4, and a pressing mechanism 5. The transfer mechanism 3 is used to move the bearing bush 7 from the storage tray 2 to the floating mechanism 4. The floating mechanism 4 includes a top rod assembly 41 and a floating sleeve assembly 42. The floating sleeve assembly 42 is sleeved on the top rod assembly 41, and a bearing bush placement position 423 is formed between the floating sleeve assembly 42 and the top rod assembly 41. The floating sleeve assembly 42 can float up and down relative to the top rod assembly 41. The top rod assembly 41 can drive the bearing bush 7 to rise and fall relative to the frame 1. The pressing mechanism 5 includes a press 51 and a floating platform 52. The press 51 is located above the floating platform 52. The floating platform 52 can float up and down relative to the frame 1. The floating platform 52 holds a housing 6 of the bearing bush 7 to be installed. The housing 6 has a bearing bush mounting hole. The floating mechanism 4 can move below the floating platform 52 so that the bearing bush 7 corresponds to the bearing bush mounting hole.

[0023] Using the bearing bush pressing equipment provided in this embodiment, the bearing bush 7 to be installed is stored in a storage tray 2. The bearing bush 7 is moved from the storage tray 2 to the floating mechanism 4 by the transfer mechanism 3, and then to the bearing bush placement position 423 between the floating sleeve assembly 42 and the push rod assembly 41. The floating mechanism 4 moves to below the floating platform 52, so that the bearing bush 7 corresponds to the bearing bush mounting hole. The push rod assembly 41 drives the bearing bush 7 to rise to near the bearing bush mounting hole. The press 51 above the floating platform 52 presses down together with the housing 6 and the floating platform 52. The edge of the bearing bush mounting hole contacts the floating sleeve assembly 42. The floating sleeve assembly 42 sinks relative to the push rod assembly 41, and the bearing bush 7 is gradually pressed into the bearing bush mounting hole. After the installation is completed, the press 51 moves back to its original position, and the floating platform 52 floats upward back to its initial position. The floating platform 52 allows some of the force exerted by the press 51 on the housing 6 during the pressing process to be alleviated and released by the floating platform 52, preventing the housing 6 from bearing excessive force and avoiding damage to the upper surface of the housing 6. During the pressing process of the press 51, the upper press 51 presses down on the housing 6 while the lower push rod assembly 41 moves upward and remains stationary. The unidirectional force of the upper press makes it easier to control the entire pressing process and improves the pressing accuracy.

[0024] Based on the above technical solutions, such as Figure 4-7 As shown, the top rod assembly 41 includes a base 411, a top rod 412, and a drive rod 413. The top rod 412 passes through the base 411, and a limiting part 4121 is provided at the top of the top rod 412 to support the bearing 7. The drive rod 413 is located below the top rod 412, and the drive rod 413 can drive the top rod 412 to rise and fall relative to the base 411.

[0025] Specifically, the drive rod 413 and the top rod 412 are coaxially arranged to improve the accuracy and stability of the driving process. When the bearing 7 needs to move upward and closer to the housing 6, the drive rod 413 rises, driving the top rod 412 to move upward relative to the base 411, thereby driving the bearing 7 at the top of the top rod 412 to move upward and closer to the housing 6. The limiting part 4121 is an annular protrusion circumferentially arranged on the outer side wall of the top rod 412, and the bottom end of the bearing 7 contacts the top wall of the annular protrusion.

[0026] Optionally, such as Figure 6 As shown, the push rod assembly 41 also includes a locking assembly, which includes a locking drive cylinder 414 and a locking member 415. The push rod 412 is provided with a locking mating groove 4122. When the push rod 412 is raised or lowered to the installation height, the locking drive cylinder 414 drives the locking member 415 to engage with the locking mating groove 4122 to fix the position of the push rod 412.

[0027] Specifically, the locking assembly is located on one side of the top rod assembly 41. The locking element 415 is a U-shaped block or a similar U-shaped block. The locking mating groove 4122 is an annular groove circumferentially located on the outer side wall of the top rod 412. When the top rod 412 moves upward and drives the bearing 7 to approach the housing 6, reaching a specified height, the locking drive cylinder 414 drives the U-shaped block to move closer to the top rod 412, so that the U-shaped block is inserted into the annular groove. The top wall of the annular groove abuts against the top wall of the U-shaped block, thereby limiting the position of the top rod 412 and fixing its position, which facilitates the subsequent pressing by the pressing mechanism 5.

[0028] Furthermore, such as Figure 2 As shown, the frame 1 is provided with a first guide rail 11 and a first driving member. The base 411 is disposed on the first guide rail 11. The first driving member can drive the base 411 to move along the first guide rail 11 toward the direction of approaching or moving away from the mounting position of the floating platform 52.

[0029] Specifically, after the bearing 7 is placed in the floating mechanism 4, the first driving member drives the base 411 to move along the first guide rail 11, causing the entire floating mechanism 4 to move along the first guide rail 11 to below the floating platform 52, so that the bearing 7 on the floating mechanism 4 corresponds to the bearing mounting hole on the housing 6. The first guide rail 11 extends along the Y-axis direction, which can accurately adjust the position of the floating mechanism 4 in the Y-axis direction. The position of the floating mechanism 4 in the X-axis direction is adjusted before pressing, so that the axis of the top rod 412 and the axis of the bearing mounting hole of the housing 6 are in the same plane along the Y-axis direction.

[0030] Furthermore, such as Figure 4 As shown, the top rod assembly 41 also includes a support plate 416 and a telescopic rod 417. The support plate 416 is disposed above the base 411 and is fixedly sleeved on the top rod 412. The telescopic rod 417 passes through the base 411. The top end of the telescopic rod 417 is fixed to the support plate 416, and the bottom end of the telescopic rod 417 is fixed to the frame 1. When the drive rod 413 drives the top rod 412 to rise and fall, the telescopic rod 417 drives the support plate 416 to rise and fall relative to the base 411.

[0031] Specifically, the support plate 416 and the telescopic rod 417 play a role in stabilizing the support. There are two or more telescopic rods 417. Taking two telescopic rods 417 as an example, the two telescopic rods 417 are symmetrically arranged on both sides of the top rod 412. When the top rod 412 is raised or lowered, the telescopic rods 417 on both sides are raised or lowered synchronously to ensure the movement stability of the top rod 412.

[0032] To improve the versatility of the floating mechanism 4, such as Figure 4 and Figure 5 As shown, the number of top rod assemblies 41, in addition to the base 411, can be multiple, as shown in the figure. There are also multiple floating sleeve assemblies 42.

[0033] Based on the above technical solutions, such as Figure 4 and Figure 8 As shown, the floating sleeve assembly 42 includes a floating sleeve 421 and an elastic element 422. The floating sleeve 421 is circumferentially sleeved on the top of the top rod 412. The floating sleeve 421, the limiting part 4121 and the outer side wall of the top rod 412 form a bearing bush placement position 423. One end of the elastic element 422 abuts against the floating sleeve 421 and the other end of the elastic element 422 abuts against the support plate 416. The floating sleeve 421 can float up and down relative to the bearing bush 7 under the action of the elastic element 422.

[0034] When the floating mechanism 4 moves below the floating platform 52 and rises to a position where the bearing 7 is close to the bearing mounting hole, the press 51 presses the housing 6 and the floating platform 52 down together until the edge of the bearing mounting hole contacts the top of the floating sleeve 421. The press 51 continues to press down, and the edge of the bearing mounting hole presses the floating sleeve 421. Under the action of the elastic element 422, the floating sleeve 421 sinks. During the sinking process, the bearing 7 is gradually exposed and, guided by the floating sleeve 421 and the edge of the bearing mounting hole, is installed into the bearing mounting hole, completing the installation. The press 51 moves up, the floating platform 52 floats up, and the floating sleeve 421 returns to its initial position under the restoring force of the elastic element 422.

[0035] To ensure the stability of the moving mechanism when moving the bearing 7 into the floating sleeve 421, the frame 1 is also provided with an auxiliary support 12. The auxiliary support 12 includes a first support and a second support. The first support and the second support are respectively arranged on both sides of the floating sleeve 421 along the X-axis. The first support and the second support are both L-shaped or similar to L-shaped, with one end fixed to the frame 1 and the other end extending close to the floating sleeve 421. The outer wall of the floating sleeve 421 is provided with an auxiliary mating groove. The ends of the first support and the second support mate with the auxiliary mating groove to help fix the position of the floating sleeve 421.

[0036] Furthermore, such as Figure 2 As shown, the floating platform 52 includes a tooling plate 521 and a plurality of elastic support legs 522. The tooling plate 521 is supported on the frame 1 by the plurality of elastic support legs 522. The tooling plate 521 is provided with clearance holes 523 and a plurality of positioning pins 524.

[0037] Specifically, such as Figure 2 As shown, the lower end of the press 51 is provided with a pressing plate 511. Multiple positioning pins 524 fix the housing 6 of the bearing bush 7 to be installed onto the tooling plate 521. The pressing plate 511 is pressed down until it contacts the housing 6. As it continues to press down, the tooling plate 521, under the action of the elastic support legs 522, begins to descend together with the housing 6. It is pressed down until the top of the floating mechanism 4 passes through the clearance hole 523 into the tooling plate 521, until the bearing bush 7 contacts the bearing bush mounting hole and installation is completed. The pressing plate 511 then retracts upwards, and the tooling plate 521 moves upwards to return to its initial position under the restoring force of the multiple elastic support legs 522. The elastic support legs 522 buffer part of the force exerted by the press 51 on the housing 6, preventing the housing 6 from bearing excessive force when the press 51 presses it, thus avoiding damage to the housing 6. The positions of the multiple positioning pins 524 can be adjusted according to different models of housing 6 to accommodate multiple models of housing 6, improving the versatility of the floating platform 52.

[0038] During the pressing process of press 51, the displacement and corresponding pressure of the press can be detected in real time, and the output is a pressing curve, providing relevant data of the pressing process, realizing the visualization of pressing, which facilitates the control of the entire pressing process and the corresponding adjustment of subsequent processes. It can monitor the stress state of the shell 6 in real time during pressing, avoid the problem of excessive or insufficient pressure during pressing, and can also stop the machine in time in case of pressing misalignment or other unexpected situations to avoid damage to the shell 6.

[0039] Furthermore, there are two floating platforms 52, and a second driving member 13 is provided above the frame 1. The second driving member 13 can drive the press 51 to move between the two floating platforms 52. When the press 51 is performing the pressing process on one of the floating platforms 52, the other floating platform 52 can perform the loading and unloading of the housing 6. The two floating platforms 52 alternately perform pressing, which improves the overall work efficiency.

[0040] Based on the above technical solutions, such as Figure 9 As shown, the bearing bush pressing equipment also includes a clamping and adjusting mechanism 8, which includes a clamping table 81 and a rotary drive motor 82. The rotary drive motor 82 can drive the clamping table 81 to rotate. The transfer mechanism 3 includes a first moving mechanism 31, which includes a three-axis drive member 311 and a first clamping member 312 disposed on the three-axis drive member 311. The first clamping member 312 can move along the XYZ axis to move the bearing bush 7 from the storage tray 2 to the clamping table 81.

[0041] Specifically, the first clamping member 312 can be a gripper or a clamping arm arranged opposite to each other. The three-axis drive member 311 is also provided with a data acquisition camera 313, which can move along the XYZ axis to acquire images of the bearing 7 placed on the clamping table 81. Based on the information provided by the image of the bearing 7, the rotation drive motor 82 drives the clamping table 81 to rotate, thereby rotating the bearing 7 to the installation angle.

[0042] Specifically, the clamping adjustment mechanism 8 adjusts the bearing shell 7, which includes a first piece and a second piece. The first and second pieces are sequentially clamped to the clamping table 81 by the first clamping member 312. The first and second pieces are placed opposite each other. The clamping table 81 includes multiple L-shaped or similar L-shaped clamping arms, which are arranged circumferentially and can move radially to clamp or release the bearing shell 7. A seam is formed between the close ends of the first and second pieces. When the acquisition camera 313 acquires images, it detects the current position of the seam. Based on the difference between the current position of the seam and the standard position of the seam when the bearing shell 7 is installed, the rotary drive motor 82 is controlled to drive the clamping table 81 to rotate, adjusting the seam of the bearing shell 7 to the standard position.

[0043] Furthermore, such as Figure 9 As shown, the bearing bush pressing equipment also includes a detection sensor 9, which is arranged opposite to the bearing bush 7 clamped by the clamping table 81 to detect the position of the feature hole of the bearing bush 7.

[0044] The frame 1 is provided with a second guide rail 14 along the X-axis. The clamping adjustment mechanism 8 is located on the second guide rail 14 and can move along the second guide rail 14. When the first clamping member 312 moves the bearing 7 from the storage tray 2 to the clamping table 81, the rotary drive motor 82 drives the clamping table 81 to rotate the bearing 7 to the marked position. Then, the clamping adjustment mechanism 8 moves along the second guide rail 14 towards the detection sensor 9 until the bearing 7 clamped by the clamping table 81 corresponds to the detection sensor 9. Specifically, the detection sensor 9 is a laser sensor. The bearing 7 rotates continuously under the drive of the rotary drive motor 82. When the laser sensor irradiates the outer wall of the bearing 7, it displays a detection value. When the bearing 7 rotates to the position where the laser sensor irradiates the feature hole, the detection of the laser sensor will change abruptly, thereby detecting the position of the feature hole of the bearing 7. The placement angle of the bearing 7 can be further adjusted according to the requirements.

[0045] Based on the above technical solutions, such as Figure 10 As shown, the transfer mechanism 3 further includes a second moving mechanism 32, which includes an X-axis drive 321, a Z-axis drive 322 disposed on the X-axis drive 321, and a second clamping member 323 disposed on the Z-axis drive 322. The second clamping member 323 can move along the X-axis and Z-axis directions to move the bearing 7 from the clamping table 81 to the floating mechanism 4.

[0046] Specifically, the second clamping member 323 includes multiple arc-shaped arms, which are arranged circumferentially in sequence, and the multiple arc-shaped arms can move in the radial direction to clamp or release the bearing shell 7.

[0047] Furthermore, such as Figure 11 As shown, the Z-axis drive component 322 is provided with a fixed plate, and the second clamping component 323 is fixed to the fixed plate. The fixed plate is also provided with two Z-axis drive cylinders 324, which are located on both sides of the second clamping component 323. The ends of the two Z-axis drive cylinders 324 are provided with pressure plates 325, which can be raised and lowered relative to the second clamping component 323 under the drive of the two Z-axis drive cylinders 324.

[0048] The pressure plate 325 is mainly used to press the bearing 7 into place after the second clamping member 323 places the bearing 7 in the bearing placement position 423 of the floating mechanism 4. The pressure plate 325 is provided with a through hole, which is provided in correspondence with the second clamping member 323 to avoid the second clamping member 323 from clamping the bearing 7.

[0049] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
