A gantry type bearing press fitting device

Abstract

This utility model belongs to the field of bearing press-fitting technology, specifically relating to a gantry-type bearing press-fitting equipment, including a gantry frame, an angle adjustment mechanism, a clamping mechanism, and a conveying mechanism. By setting up the angle adjustment mechanism, the operator can load and unload the bearing in place, and the bearing is positioned far from the operator during press-fitting, thus greatly reducing the risk of injury. By setting up the clamping mechanism, the second arc-shaped clamping plate, in conjunction with the first arc-shaped clamping plate, clamps and limits the bearing, thereby improving the bearing's stability during press-fitting and further reducing the risk of injury. By setting up the conveying mechanism, when the disc rotates 180 degrees, the first and second arc-shaped clamping plates clamp the bearing to be press-fitted. Controlling the servo motor to drive the disc to rotate 180 degrees in the opposite direction can rotate the bearing back to its original position. At this time, the clamping mechanism releases the bearing's limitation, making it convenient for the operator to remove the bearing for replacement.

Description

Technical Field

[0001] This utility model belongs to the field of bearing press-fitting technology, specifically relating to a gantry-type bearing press-fitting equipment. Background Technology

[0002] Bearing press fitting is the assembly process of precisely installing bearings onto shafts or housings. Bearing press fitting can be performed using mechanical force or hydraulic pressure. Correct press fitting process can ensure tight contact of bearings, prevent bearings from moving or abnormally wearing during equipment operation, and ensure the safe operation of equipment.

[0003] Currently, bearings are typically manufactured by manual loading and pressing. If workers are too close to the pressing equipment, they are easily crushed and injured. During the pressing process, objects may be ejected and hit workers, making the situation quite dangerous. Practical content

[0004] The purpose of this invention is to provide a gantry-type bearing press-fitting equipment, which solves the problems of existing technology where bearings are usually manually loaded and pressed during production, workers are easily crushed and injured when they are too close to the press-fitting equipment, and objects may be splashed out and hit workers during the press-fitting process, which is a high degree of danger.

[0005] The specific technical solution adopted in this utility model is as follows: A gantry-type bearing press-fitting equipment includes: The gantry frame has a base plate fixedly installed on its bottom surface; An angle adjustment mechanism is provided on the top surface of the base plate and is used to drive the bearing to rotate. A clamping mechanism is disposed on the top surface of the angle adjustment mechanism, and the clamping mechanism is used to improve the stability of the bearing; A conveying mechanism is provided between the gantry and the base plate. The conveying mechanism is used to drive the clamping mechanism to clamp and limit the bearing while the angle adjustment mechanism drives the bearing to rotate.

[0006] In a preferred embodiment, the angle adjustment mechanism includes a servo motor and a disc. A worktable and a servo motor are fixedly mounted on the top surface of the base plate. A mounting groove is provided on the bottom surface of the worktable. The servo motor is located inside the mounting groove. The top surface of the output end of the servo motor passes through the worktable and is fixedly mounted on the disc. A circular groove adapted to the disc is provided on the top surface of the worktable. The disc is rotatably connected to the worktable through the circular groove.

[0007] In a preferred embodiment, a cylinder is disposed above the disc, the top surface of the cylinder is fixedly connected to the inner top surface of the gantry frame, and a pressing head is fixedly disposed on the bottom surface of the output end of the cylinder.

[0008] In a preferred embodiment, the clamping mechanism includes a first arc-shaped clamping plate, a second arc-shaped clamping plate, an L-shaped guide rod, a fixing plate, and a baffle. The first arc-shaped clamping plate is fixedly disposed on the top surface of the disc, and the second arc-shaped clamping plate is slidably connected to the top surface of the disc. Symmetrical L-shaped guide rods are fixedly disposed on the left and right sides of the second arc-shaped clamping plate, and a baffle is fixedly disposed at the other end of the L-shaped guide rod. Symmetrical fixing plates are fixedly disposed on the top surface of the disc, and the L-shaped guide rod passes through the fixing plate and is slidably connected to the fixing plate.

[0009] In a preferred embodiment, the conveying mechanism includes a threaded rod, a threaded sleeve, a collar, an L-shaped fixing rod, a fixing block, a vertical groove, and a connecting rod. A threaded rod is fixedly disposed at the center of the top surface of the disc, and a threaded sleeve is disposed through the outer side of the threaded rod. An annular groove is disposed at the bottom of the outer side of the threaded sleeve, and a collar that fits the annular groove is disposed inside the annular groove. A symmetrical L-shaped fixing rod is fixedly disposed on the top surface inside the gantry frame, and a fixing block is fixedly disposed at the other end of the L-shaped fixing rod. A symmetrical vertical groove is disposed on the outer side of the threaded sleeve, and a connecting rod is hinged to the outer side of the collar.

[0010] In a preferred embodiment, the top of the threaded rod is rotatably connected to the gantry frame via a bearing, the threaded rod is threadedly connected to the threaded sleeve, the collar is rotatably connected to the threaded sleeve via an annular groove, the fixing block is adapted to the vertical groove, the fixing block is slidably connected to the threaded sleeve via the vertical groove, and the end of the connecting rod away from the collar is hinged to the back of the second arc-shaped clamping plate.

[0011] The technical effects achieved by this utility model are as follows: This utility model, by setting an angle adjustment mechanism, allows the operator to place the bearing to be pressed on the top surface of the disc, and control the servo motor to drive the disc to rotate 180 degrees to directly below the pressing head. This facilitates the downward movement of the pressing head to press the bearing. The operator can place and unload the bearing in place, and the bearing is far away from the operator during pressing, which can greatly reduce the risk of injury to the operator. This utility model, by setting up a clamping mechanism, allows workers to place the bearing to be press-fitted between the first arc-shaped clamping plate and the second arc-shaped clamping plate. The second arc-shaped clamping plate moves closer to the first arc-shaped clamping plate and cooperates with the first arc-shaped clamping plate to press the bearing, thereby clamping and limiting the bearing, thus improving the stability of the bearing during press-fitting and further reducing the risk of injury to workers. This invention utilizes a conveying mechanism. When the disc rotates to drive the bearing to be pressed, the disc's rotation simultaneously drives the threaded rod and clamping mechanism to rotate. The rotation of the threaded rod causes the threaded sleeve to move downwards, which in turn causes the collar to move downwards. Simultaneously, the collar rotates relative to the threaded sleeve, and this downward movement of the collar causes the connecting rod to rotate. The rotation of the connecting rod causes the second arc-shaped clamping plate to move closer to the first arc-shaped clamping plate. When the disc rotates 180 degrees, the first and second arc-shaped clamping plates clamp the bearing to be pressed. When the bearing is pressed, the servo motor drives the disc to rotate 180 degrees in the opposite direction, which in turn drives the bearing back to its original position. At this point, the clamping mechanism releases its restriction on the bearing, making it convenient for workers to remove the bearing for replacement. Attached Figure Description

[0018] Please see the appendix Figures 1 to 3 As shown, this utility model provides a gantry-type bearing press-fitting device, including: a gantry frame 100, an angle adjustment mechanism 300, a clamping mechanism 500, and a conveying mechanism 600. The gantry frame 100 has a U-shaped plate structure. A base plate 200 is fixedly installed on the bottom surface of the gantry frame 100, and a worktable 201 is fixedly installed on the top surface of the base plate 200. A cylinder 401 is fixedly installed on the top surface inside the gantry frame 100, and a press-fitting head 402 is fixedly installed on the bottom surface of the output end of the cylinder 401.

[0019] In a preferred embodiment, please refer to Figures 1 to 3 An angle adjustment mechanism 300 is provided on the top surface of the base plate 200. The angle adjustment mechanism 300 consists of a servo motor 301 and a disc 302. The servo motor 301 is fixedly installed on the top surface of the base plate 200. The bottom surface of the worktable 201 is provided with a mounting groove. The servo motor 301 is installed inside the mounting groove. The top surface of the output end of the servo motor 301 passes through the worktable 201 and is fixedly installed with the disc 302. The top surface of the worktable 201 is provided with a circular groove that fits the disc 302. The disc 302 is rotatably connected to the worktable 201 through the circular groove. Controlling the servo motor 301 can drive the disc 302 to rotate. The worktable 201 is used to support the disc 302.

[0020] In this embodiment, the worker places the bearing to be pressed on the top surface of the disc 302 and controls the servo motor 301 to drive the disc 302 to rotate 180 degrees to directly below the pressing head 402. This allows the pressing head 402 to move downwards to press the bearing. The worker can place and unload the bearing in place, and the bearing is far away from the worker during pressing, which greatly reduces the risk of injury to the worker.

[0021] In a preferred embodiment, please refer to Figures 1 to 4Angle adjustment mechanism 300 has a clamping mechanism 500 on its top surface. The clamping mechanism 500 consists of a first arc-shaped clamping plate 501, a second arc-shaped clamping plate 502, an L-shaped guide rod 503, a fixing plate 504, and a baffle 505. The first arc-shaped clamping plate 501 is fixedly installed on the top surface of the disc 302. The second arc-shaped clamping plate 502 is slidably connected to the top surface of the disc 302. Symmetrical L-shaped guide rods 503 are fixedly installed on the left and right sides of the second arc-shaped clamping plate 502. A baffle 505 is fixedly installed at the other end of the L-shaped guide rod 503. Symmetrical fixing plates 504 are fixedly installed on the top surface of the disc 302. The L-shaped guide rod 503 passes through the fixing plate 504 and is slidably connected to the fixing plate 504. The L-shaped guide rod 503, in conjunction with the fixing plate 504, guides the movement of the second arc-shaped clamping plate 502.

[0022] In this embodiment, the worker places the bearing to be press-fitted between the first arc-shaped clamping plate 501 and the second arc-shaped clamping plate 502. The second arc-shaped clamping plate 502 moves closer to the first arc-shaped clamping plate 501 and cooperates with the first arc-shaped clamping plate 501 to press the bearing, which can clamp and limit the bearing, thereby improving the stability of the bearing during press-fitting and further reducing the risk of injury to the worker.

[0023] In a preferred embodiment, please refer to Figures 1 to 4 A conveying mechanism 600 is provided between the gantry frame 100 and the base plate 200. The conveying mechanism 600 consists of a threaded rod 601, a threaded sleeve 602, a collar 603, an L-shaped fixing rod 604, a fixing block 605, a vertical groove 606, and a connecting rod 607. A threaded rod 601 is fixedly provided at the center of the top surface of the disc 302. A threaded sleeve 602 is provided through the outside of the threaded rod 601. An annular groove is provided at the bottom of the outside of the threaded sleeve 602. A collar 603 that fits the annular groove is provided inside the annular groove. A symmetrical L-shaped fixing rod 604 is fixedly provided on the top surface inside the gantry frame 100. A fixing block 605 is fixedly provided at the other end of the L-shaped fixing rod 604. A symmetrical vertical groove 606 is provided on the outside of the threaded sleeve 602. The vertical groove 606 is located above the annular groove. A connecting rod 607 is hinged to the outside of the collar 603.

[0024] In this embodiment, the top of the threaded rod 601 is rotatably connected to the gantry frame 100 via a bearing. The threaded rod 601 is threadedly connected to the threaded sleeve 602. The collar 603 is rotatably connected to the threaded sleeve 602 via an annular groove. The fixing block 605 is adapted to the vertical groove 606. The fixing block 605 is slidably connected to the threaded sleeve 602 via the vertical groove 606. The end of the connecting rod 607 away from the collar 603 is hinged to the back of the second arc-shaped clamp 502.

[0025] In this embodiment, when the disc 302 drives the bearing to be press-fitted to rotate, the rotation of the disc 302 simultaneously drives the threaded rod 601, the first arc-shaped clamping plate 501, the second arc-shaped clamping plate 502, the L-shaped guide rod 503, the fixing plate 504, and the baffle 505 to rotate. The rotation of the second arc-shaped clamping plate 502 drives the connecting rod 607 and the collar 603 to rotate. The rotation of the threaded rod 601 drives the threaded sleeve 602 to move downward. The fixing block 605, in conjunction with the vertical groove 606, guides the movement of the threaded sleeve 602. The movement of the threaded sleeve 602 drives the collar 603 to move downward. At the same time, the collar 607... 3. The relative threaded sleeve 602 rotates, and the collar 603 moves downward, causing the connecting rod 607 to rotate. The rotation of the connecting rod 607 can cause the second arc-shaped clamping plate 502 to move closer to the first arc-shaped clamping plate 501. When the disc 302 rotates 180 degrees, the first arc-shaped clamping plate 501 and the second arc-shaped clamping plate 502 just clamp the bearing to be pressed. When the bearing is pressed, the servo motor 301 is controlled to drive the disc 302 to rotate 180 degrees in the opposite direction, which can drive the bearing to rotate back to its original position. At this time, the clamping mechanism 500 has released the limit on the bearing, so that the staff can easily remove the bearing for replacement.

[0026] The working principle of this utility model is as follows: When using this device, the operator places the bearing to be pressed between the first arc-shaped clamping plate 501 and the second arc-shaped clamping plate 502 on the top surface of the disc 302. The servo motor 301 is then controlled to rotate the disc 302 180 degrees to directly below the pressing head 402. Simultaneously, the rotation of the disc 302 drives the threaded rod 601, the first arc-shaped clamping plate 501, the second arc-shaped clamping plate 502, the L-shaped guide rod 503, the fixing plate 504, and the baffle 505 to rotate. The rotation of the second arc-shaped clamping plate 502 drives the connecting rod 607 and the collar 603 to rotate. 1. Rotation drives the threaded sleeve 602 to move downwards. The movement of the threaded sleeve 602 drives the collar 603 to move downwards. At the same time, the collar 603 rotates relative to the threaded sleeve 602. The downward movement of the collar 603 drives the connecting rod 607 to rotate. The rotation of the connecting rod 607 can drive the second arc-shaped clamp 502 to approach the first arc-shaped clamp 501. When the disc 302 rotates 180 degrees, the first arc-shaped clamp 501 and the second arc-shaped clamp 502 just clamp the bearing to be pressed. The control cylinder 401 drives the pressing head 402 to move downwards to press the bearing.

[0027] When the bearing is press-fitted, the control servo motor 301 drives the disc 302 to rotate 180 degrees in the opposite direction, which can drive the bearing to rotate back to its original position. At this time, the clamping mechanism 500 has released the limit on the bearing, which makes it convenient for the staff to remove the bearing for replacement. The staff can put and unload the bearing in place, and the bearing is far away from the staff during the press-fitting process, which can greatly reduce the risk of injury to the staff. The second arc-shaped clamping plate 502 moves towards the first arc-shaped clamping plate 501 and cooperates with the first arc-shaped clamping plate 501 to press the bearing, which can clamp and limit the bearing, thereby improving the stability of the bearing during the press-fitting process and further reducing the risk of injury to the staff.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
