Description

Technical Field

[0001] This utility model relates to the field of press-fitting machine technology, specifically to a bearing seal cover press-fitting machine with a pressure equalization mechanism. Background Technology

[0002] A bearing seal cover press-fitting machine with a pressure equalization mechanism is a device used for installing bearing seal covers. This device is designed with a special pressure equalization mechanism to ensure a uniform pressure distribution during the press-fitting process of the bearing seal cover, and to avoid bearing damage or improper seal cover assembly caused by uneven pressure.

[0003] According to a public disclosure (Publication No.: CN 119870934 A), a bearing press-fitting mechanism includes a cylinder, a cylinder mounting plate, a back plate, a base plate, a safety light curtain, a press connector, a product fixing plate, a displacement sensor, a press head transfer plate, a press-fitting head, a vacuum generator, a product fixing plate, a bottom cover fixing block, a support column, a bottom cover fixing seat, a photoelectric upright, a photoelectric sensor, and a floating block. The advantage is that the product bottom cover is manually placed on the bottom cover fixing block, and the photoelectric sensor detects the signal.

[0004] The aforementioned method, through the cooperation between components such as cylinders and cylinder mounting plates, is insufficient to prevent the pressure plate from tilting and the bearings from shifting left and right during the pressing process. This results in pressing deviations due to force offset, making it difficult to guarantee the accuracy of the pressing position, and requires improvement. Utility Model Content

[0006] According to one aspect, at least one embodiment of the present invention provides a bearing seal cap press-fitting machine with a pressure equalization mechanism, comprising a press-fitting machine body, a cylinder disposed at the top of the press-fitting machine body, a stable and equalizing pressure cap pressing assembly disposed at the bottom of the press-fitting machine body, the stable and equalizing pressure cap pressing assembly comprising a pressing platform, the side of the pressing platform being fixedly connected to the side of the press-fitting machine body, a short rod being fixedly connected to the inner wall of the press-fitting machine body, a motor being fixedly connected to one end of the short rod, a gear being fixedly connected to the output shaft of the motor, a rack one being slidably connected to the top of the press-fitting machine body, a rack two being slidably connected to the top of the press-fitting machine body, a connecting rod being fixedly connected to one end of the rack one, a fixing plate being fixedly connected to one end of the connecting rod, a pressure plate being fixedly connected to the telescopic end of the cylinder, and a telescopic rod being fixedly connected to the bottom of the press-fitting machine body, the telescopic end of the telescopic rod being fixedly connected to the top of the pressure plate.

[0007] For example, in a bearing sealing cover press-fitting machine with a pressure equalization mechanism provided in at least one embodiment of the present invention, the following are also included: the rack one and the gear mesh with each other, the rack two and the gear mesh with each other, and the connecting rod and the fixing plate are provided in two symmetrical positions along the vertical central axis of the press-fitting table. The design of two fixing plates is beneficial to clamp the side of the bearing at the same time when the fixing plate moves.

[0008] For example, in a bearing sealing cover press-fitting machine with a pressure equalization mechanism provided in at least one embodiment of the present invention, the fixed plate is located on the side of the press-fitting table, the press-fitting table is located on the displacement trajectory of the fixed plate, and the pressure plate is located on the top of the press-fitting table. This design is beneficial to clamp the bearing placed on the press-fitting table when the fixed plate moves.

[0009] For example, in a bearing seal cover press-fitting machine with a pressure equalization mechanism provided in at least one embodiment of the present invention, a limiting groove is formed on the inner wall of the press-fitting machine body, a limiting rod is slidably connected on the inner wall of the limiting groove, and the end of the limiting rod away from the limiting groove is fixedly connected to the top of the rack two. The design of the limiting rod is beneficial to restricting the movement trajectory of the rack two.

[0010] For example, in a bearing sealing cap press-fitting machine with a pressure equalization mechanism provided in at least one embodiment of the present invention, a switch is provided on the outer wall of the motor, a controller is provided on the side of the press-fitting machine body, and an alarm light is provided on the top of the controller. The design of the controller is conducive to direct control of the press-fitting machine body.

[0011] According to another aspect, at least one embodiment of the present invention also provides a bearing sealing cap press-fitting machine with a pressure equalization mechanism, comprising: a circulating heat dissipation assembly disposed on the side of the press-fitting machine body, the circulating heat dissipation assembly including a storage tank, the side of the storage tank being fixedly connected to the side of the press-fitting machine body, a partition plate being fixedly connected to the inner wall of the storage tank, a rectangular plate being fixedly connected to the side of the storage tank, a circulating pump disposed on the top of the rectangular plate, a heat dissipation pipe being fixedly connected to the bottom of the press-fitting platform, a water outlet pipe passing through one end of the circulating pump, the end of the water outlet pipe away from the circulating pump passing through the outer wall of the heat dissipation pipe, a water inlet pipe passing through one end of the circulating pump, the end of the water inlet pipe away from the circulating pump passing through the side of the storage tank, a belt disposed on the output shaft of the motor, a rotating rod being connected to the output shaft of the motor via the belt drive, one end of the rotating rod passing through the top of the storage tank, and a stirring rod being fixedly connected to the circumferential surface of the rotating rod. Water flows in the heat dissipation pipe to perform water cooling circulation heat dissipation on the bearing on the press-fitting platform, and the water inside the storage tank is stirred by the stirring rod to improve heat exchange.

[0012] For example, in a bearing sealing cap press-fitting machine with a pressure equalization mechanism provided in at least one embodiment of the present invention, the following is also included: a plurality of stirring rods are provided and arranged in a linear array on the circumferential surface of the rotating rod, and the stirring rods are located on the inner wall of the storage tank. Designing a plurality of stirring rods is beneficial to improving stirring efficiency.

[0013] For example, in a bearing sealing cover press-fitting machine with a pressure equalization mechanism provided in at least one embodiment of the present invention, the stirring rod is located at the top of the partition plate, and the rotating rod and belt are located on the side of the connecting rod and rack. This design is beneficial to not affecting the normal rotation of the belt.

[0014] For example, in a bearing sealing cover press-fitting machine with a pressure equalization mechanism provided in at least one embodiment of the present invention, a replenishment pipe is provided through the side of the storage tank. Two replenishment pipes are provided and are arranged in a linear array on the side of the storage tank.

The design of the display is conducive to directly displaying the parameters of the press-fitting machine.

[0016] The beneficial effects of this utility model are as follows: In this invention, the cooperation between the pressing platform, pressure plate, and fixing plate inside the stable and balanced pressure cover assembly enables the pressure plate to be vertically guided by the telescopic rod, effectively preventing the pressure plate from tilting and ensuring that the pressure is applied vertically and evenly to the workpiece. This avoids pressing deviations caused by force offset and ensures the assembly accuracy of the sealing cover and the bearing. The motor drives the gear, rack one, and rack two to move the fixing plate relative to each other, which can accurately limit the bearing on the pressing platform and prevent the bearing from shifting left or right during the pressing process, further ensuring the accuracy of the pressing position.

[0017] In this invention, the cooling pipes, water outlet pipes, water inlet pipes, belts, and other components inside the circulating heat dissipation assembly work together to continuously cool the pressing platform and bearings with cold water flowing inside the cooling pipes. This avoids the impact of thermal expansion and contraction on the pressing dimensions of the sealing cap, ensuring assembly consistency. The motor drives the stirring rod to agitate the upper water layer, promoting uniform heat exchange between the upper and lower water layers and preventing the lower cooling water from heating up too quickly in certain areas, thus ensuring stable heat dissipation.

[0026] like Figures 1-5 The diagram illustrates a bearing seal cap press-fitting machine with a pressure equalization mechanism according to an embodiment of the present invention. The machine includes a press-fitting machine body 1, a cylinder 2 mounted on the top of the body 1, and a stable and equalizing pressure cap pressing assembly 3 mounted on the bottom of the body 1. The stable and equalizing pressure cap pressing assembly 3 includes a pressing platform 31, the side of which is fixedly connected to the side of the press-fitting machine body 1. A short rod 36 is fixedly connected to the inner wall of the body 1, and one end of the short rod 36 is fixedly connected to an electric... The machine 37 has a gear 38 fixedly connected to the output shaft of the motor 37. The top of the press machine body 1 is slidably connected to a rack 39 and a rack 310. One end of the rack 39 is fixedly connected to a connecting rod 311, and one end of the connecting rod 311 is fixedly connected to a fixing plate 312. The telescopic end of the cylinder 2 is fixedly connected to a pressure plate 32. The bottom of the press machine body 1 is fixedly connected to a telescopic rod 33, and the telescopic end of the telescopic rod 33 is fixedly connected to the top of the pressure plate 32.

[0027] Rack 1 39 and gear 38 mesh with each other, rack 2 310 and gear 38 mesh with each other, connecting rod 311 and fixing plate 312 are provided in two, and are symmetrical to each other along the vertical central axis of press table 31. The design of two fixing plates 312 is beneficial to clamp the side of the bearing when the fixing plate 312 moves.

[0028] The fixing plate 312 is located on the side of the pressing table 31, the pressing table 31 is located on the displacement trajectory of the fixing plate 312, and the pressure plate 32 is located on the top of the pressing table 31. This design is beneficial to clamp the bearing placed on the pressing table 31 when the fixing plate 312 moves.

[0029] A limiting groove 313 is provided on the inner wall of the press machine body 1. A limiting rod 314 is slidably connected to the inner wall of the limiting groove 313. The end of the limiting rod 314 away from the limiting groove 313 is fixedly connected to the top of the rack 310. The design of the limiting rod 314 is beneficial to restricting the movement trajectory of the rack 310.

[0030] A switch is provided on the outer wall of the motor 37, and a controller 34 is provided on the side of the press machine body 1. An alarm light 35 is provided on the top of the controller 34. The design of the controller 34 is conducive to direct control of the press machine body 1.

[0031] This embodiment provides a bearing sealing cap press-fitting machine with a pressure equalization mechanism. Through the mutual cooperation between the pressing table 31, pressure plate 32, and fixed plate 312 inside the stable and equalized pressure cap pressing assembly 3, the pressure plate 32 is vertically guided by the telescopic rod 33, which effectively prevents the pressure plate 32 from tilting, ensures that the pressure is applied vertically and evenly to the workpiece, avoids pressing deviation caused by force offset, and ensures the assembly accuracy of the sealing cap and the bearing. The motor 37 drives the gear 38, rack 1 39, and rack 2 310 to move the fixed plate 312 relative to each other, which can accurately limit the bearing on the pressing table 31, prevent the bearing from shifting left and right during the pressing process, and further ensure the accuracy of the pressing position.

[0032] See in some examples Figures 1-5The bearing seal cover to be pressed is placed on the pressing table 31. The controller 34 starts the cylinder 2, and the telescopic end of the cylinder 2 pushes the pressure plate 32 downward. During the downward movement of the pressure plate 32, the telescopic rod 33 at the bottom of the pressing machine body 1 extends and retracts synchronously to provide vertical guidance for the pressure plate 32, prevent the pressure plate 32 from tilting, and ensure that the pressure of the pressure plate 32 on the workpiece is vertical and uniform. The pressure plate 32 continues to press down, uniformly pressing the bearing seal cover to the designated position. During the pressing process, the display 315 displays key parameters such as pressure and displacement in real time, which is convenient for the operator to monitor the uniformity of pressing. The motor 37 is set as a three-phase asynchronous motor. The motor 37 can rotate in both directions. Start the motor 37 to make the motor rotate in the forward direction. The forward rotation of the motor 37 drives the gear 38 to rotate in the forward direction. The gear 38 meshes with the rack 39 and the rack 310 at the same time. When the gear 38 rotates in the forward direction, it will drive the rack 39 and the rack 310 to move, so that the rack 39 and the rack 310 move relative to each other. The relative movement of racks 39 and 310 drives the relative movement of two connecting rods 311 and two fixed plates 312. The two fixed plates 312 are located on the left and right sides of the pressing table 31, respectively. When the two fixed plates 312 move relative to each other, they move closer to the pressing table 31. Bearings are placed on the pressing table 31. When the fixed plates 312 move relative to each other, they block the two sides of the bearings to limit their movement, preventing the bearings from moving to the left and right when the pressing plate 32 is pressing. The telescopic rod 33 provides vertical guidance for the pressing plate 32, effectively preventing the pressing plate 32 from tilting, ensuring that the pressure is applied vertically and evenly to the workpiece, avoiding pressing deviations caused by force offset, and ensuring the assembly accuracy of the sealing cover and the bearing. The motor 37 drives the gears 38, racks 39 and 310 to move the fixed plates 312 relative to each other, which can accurately limit the bearings on the pressing table 31, prevent the bearings from shifting left and right during the pressing process, and further ensure the accuracy of the pressing position.

[0033] refer to Figures 1-5In some embodiments, a bearing seal cap press-fitting machine with a pressure equalization mechanism further includes: a circulating heat dissipation assembly 4 disposed on the side of the press-fitting machine body 1; the circulating heat dissipation assembly 4 includes a storage tank 41; the side of the storage tank 41 is fixedly connected to the side of the press-fitting machine body 1; a partition plate 410 is fixedly connected to the inner wall of the storage tank 41; a rectangular plate 42 is fixedly connected to the side of the storage tank 41; a circulating pump 43 is disposed on the top of the rectangular plate 42; a heat dissipation pipe 45 is fixedly connected to the bottom of the press-fitting table 31; and a water outlet pipe 44 extends through one end of the circulating pump 43, with the water outlet pipe 44 being away from the circulating pump 43. One end of the circulating pump 43 is inserted through the outer wall of the heat dissipation pipe 45, and the other end of the circulating pump 43 is inserted through the water inlet pipe 46. The end of the water inlet pipe 46 away from the circulating pump 43 is inserted through the side of the storage tank 41. A belt 47 is installed on the output shaft of the motor 37. The output shaft of the motor 37 is connected to the rotating rod 48 through the belt 47. One end of the rotating rod 48 is inserted through the top of the storage tank 41. A stirring rod 49 is fixedly connected to the circumference of the rotating rod 48. Water flows in the heat dissipation pipe 45 to circulate and cool the bearings on the pressing table 31. The stirring rod 49 stirs the water inside the storage tank 41 to improve heat exchange.

[0034] Several stirring rods 49 are provided and are arranged in a linear array on the circumference of the rotating rod 48. The stirring rods 49 are located on the inner wall of the storage tank 41. Designing several stirring rods 49 is beneficial to improving stirring efficiency.

[0035] The stirring rod 49 is located on top of the partition plate 410, and the rotating rod 48 and belt 47 are located on the side of the connecting rod 311 and rack 39. This design helps to avoid affecting the normal rotation of the belt 47.

[0036] A replenishment pipe 411 runs through the side of the storage tank 41. There are two replenishment pipes 411, which are arranged in a linear array on the side of the storage tank 41. The design of the replenishment pipe 411 is conducive to replenishing and draining the water inside the storage tank 41.

[0037] A plug is provided at the end of the replenishment tube 411 away from the storage box 41, and a display 315 is provided on the side of the press body 1. The design of the display 315 is conducive to directly displaying the parameters of the press.

[0038] In this embodiment, through the cooperation of components such as the heat dissipation pipe 45, water outlet pipe 44, water inlet pipe 46, and belt 47 inside the circulating heat dissipation component 4, the cold water flowing in the heat dissipation pipe 45 continuously cools the pressing table 31 and bearings, which can avoid the impact of thermal expansion and contraction on the pressing size accuracy of the sealing cover and ensure assembly consistency. The motor 37 drives the stirring rod 49 to stir the upper water, promote uniform heat exchange between the upper and lower water layers, avoid excessive local temperature rise of the lower cooling water, and ensure stable heat dissipation effect.

[0039] In this embodiment, the storage tank 41 is used to store water. A partition plate 410 divides the interior of the storage tank 41 into two parts. The water in the upper layer is used for heat exchange with the water in the lower layer, while the water in the lower layer dissipates heat from the bearings at the top of the pressing platform 31. The circulation pump 43 is started, drawing out the water from the lower layer through the inlet pipe 46, and then injecting the water into the heat dissipation pipe 45 through the outlet pipe 44. The water flows within the heat dissipation pipe 45, relieving heat from the bearings at the top of the pressing platform 31. The aforementioned motor 37 rotates, driving the rotating rod 48 and the stirring rod 49 to rotate. The stirring rod 49 is located within the storage tank 41. Inside the storage tank 41, the stirring rod 49 rotates within the upper layer of water, promoting water flow and facilitating a more uniform heat exchange between the upper and lower layers. During the pressing process, bearing friction generates heat, and excessively high temperatures may cause thermal deformation of the workpiece. The cold water flowing through the heat dissipation pipe 45 continuously cools the pressing table 31 and the bearings, preventing thermal expansion and contraction from affecting the pressing dimensional accuracy of the sealing cap and ensuring assembly consistency. The motor 37 drives the stirring rod 49 to agitate the upper layer of water, promoting uniform heat exchange between the upper and lower layers and preventing the lower cooling water from heating up too quickly in certain areas, thus ensuring stable heat dissipation.
