Description

Technical Field

[0001] This utility model relates to the field of nylon bearing press-fitting technology, specifically a nylon bearing press-fitting machine that prevents deformation. Background Technology

[0002] Nylon bearings, also known as plastic bearings, are bearings made of nylon material and offer numerous advantages and wide applications. Nylon bearings are self-lubricating, requiring no additional lubricant, and are suitable for various working environments, including some special chemical media environments. Nylon material has good resistance to most chemicals and solvents, making nylon bearings widely used in the chemical industry. Compared to metal bearings, nylon bearings are lighter, helping to reduce the overall weight of mechanical equipment and aligning with the modern trend of lightweight design.

[0003] Nylon bearing press-fitting requires a nylon bearing press-fitting machine. Existing nylon bearings are often installed using a bearing press-fitting machine, a specialized device for installing bearings. This machine uses a hydraulic system or mechanical force to apply pressure, installing the bearing onto the corresponding shaft or housing bore. However, in traditional press-fitting processes, the good elasticity of nylon material makes the bearing prone to deformation under uneven stress. Furthermore, traditional press-fitting machines suffer from low efficiency and uneven pressing when installing nylon bearings, affecting production efficiency and bearing performance, and failing to meet production requirements. Therefore, a deformation-resistant nylon bearing press-fitting machine is proposed to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a deformation-resistant nylon bearing press-fitting machine, which boasts advantages such as high press-fitting efficiency and good press-fitting quality. It solves the problems inherent in existing technologies where nylon bearings are often installed using bearing press-fitting machines. Bearing press-fitting machines are specialized equipment for installing bearings, using hydraulic systems or mechanical force to apply pressure and install the bearing onto the corresponding shaft or seat hole. However, in traditional press-fitting processes, the good elasticity of nylon material easily leads to bearing deformation under uneven stress. Furthermore, traditional press-fitting machines suffer from low efficiency and uneven press-fitting when installing nylon bearings, affecting production efficiency and bearing performance, and failing to meet production requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant nylon bearing press-fitting machine, comprising a base, a mounting box fixedly connected to the top of the base, a controller fixedly installed outside the base, and a mounting frame fixedly connected to the top of the base. The mounting box is provided with a feeding mechanism extending to its outside for feeding the nylon bearing body. The top of the mounting box is provided with four positioning devices for accurately positioning the nylon bearing body.

[0006] The feeding mechanism includes a geared motor fixedly installed on the bottom wall of the mounting box and a rotating shaft rotatably connected to the inside of the mounting box and extending to its outside. A transmission gear is fixedly connected to the output shaft of the geared motor, and a driven gear meshing with the transmission gear is fixedly connected to the outside of the rotating shaft. A mounting plate is fixedly connected to the end of the rotating shaft away from the mounting box.

[0007] The positioning device includes two mounting bases fixedly connected to one side of the top of the mounting plate and a bearing fixing base fixedly connected between the two mounting bases. An electric push rod is fixedly installed inside each of the two mounting bases, and a clamp is fixedly connected to the output end of each of the two electric push rods.

[0008] Furthermore, the geared motor and the controller are electrically connected, and a limit bearing adapted to the rotating shaft is fixedly installed inside the mounting box.

[0009] Furthermore, the mounting plate is a solid disc, and a guide rod extending into the mounting box is fixedly connected to the bottom of the mounting plate. The mounting box has an annular groove that matches the guide rod, and the guide rod and the annular groove are slidably connected.

[0010] Furthermore, the four positioning devices are arranged in a ring shape on the top of the mounting plate, and there are several electric push rods, all of which are electrically connected to the controller.

[0011] Furthermore, the upper surface of the mounting bracket is provided with a buffer pressing mechanism extending to its lower surface. The buffer pressing mechanism includes a hydraulic cylinder fixedly installed on the upper surface of the mounting bracket and extending to its lower surface. A connecting plate is fixedly connected to the output end of the hydraulic cylinder. A fixing plate is fixedly connected to the bottom of the connecting plate. A pressing head is fixedly installed at the bottom of the fixing plate. The pressing head is located on the upper surface of the bearing fixing seat.

[0012] Furthermore, an elastic telescopic rod is fixedly installed on the top of the fixing plate, and a spring is fixedly connected between the connecting plate and the fixing plate.

[0013] Furthermore, the end of the elastic telescopic rod away from the fixed plate is fixedly connected to the bottom of the connecting plate, and the spring is wrapped around the outside of the elastic telescopic rod.

[0014] Furthermore, a limiting rod extending to the upper surface of the mounting frame is fixedly connected to the top of the connecting plate, and the limiting rod is slidably connected inside the mounting frame.

[0015] Compared with the prior art, this utility model provides a deformation-resistant nylon bearing press-fitting machine, which has the following beneficial effects:

[0016] 1. This anti-deformation nylon bearing press-fitting machine uses a controller to start a reduction motor that drives a transmission gear to rotate. The rotating transmission gear meshes with the driven gear, rotating shaft, and mounting plate, causing them to rotate intermittently. This feeds the nylon bearing body into the press-fitting position. The controller then activates an electric push rod to extend or retract, moving the clamps closer to or further away, thus limiting the nylon bearing body and ensuring accurate positioning. This improves press-fitting precision and prevents the nylon bearing body from deviating from the predetermined track. It achieves automatic feeding and precise positioning, effectively improving press-fitting efficiency and achieving the advantage of high press-fitting efficiency.

[0017] 2. This anti-deformation nylon bearing press uses a controller to activate the hydraulic cylinder to extend and retract, causing the connecting plate, fixing plate, and press head to move downwards, thereby pressing the nylon bearing. By setting a limit rod, the press head can press evenly. By setting an elastic telescopic rod and spring, the impact on the nylon bearing body during the pressing process is reduced, preventing deformation and damage to the nylon bearing body, thus achieving the advantage of good pressing quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This embodiment of a deformation-resistant nylon bearing press-fitting machine includes a base 1, a mounting box 2 fixedly connected to the top of the base 1, a controller 3 fixedly installed outside the base 1, and a mounting bracket 4 fixedly connected to the top of the base 1. The mounting box 2 is provided with a feeding mechanism 5 extending to its outside for feeding the nylon bearing body. The top of the mounting box 2 is provided with four positioning devices 6 for accurately positioning the nylon bearing body. The feeding mechanism 5 includes a reduction motor 51 fixedly installed on the bottom wall of the mounting box 2 and a rotating shaft 53 rotatably connected to the inside of the mounting box 2 and extending to its outside. A transmission gear 52 is fixedly connected to the output shaft of the reduction motor 51. A driven gear 54 meshing with the transmission gear 52 is fixedly connected to the outside of the rotating shaft 53. A mounting plate 55 is fixedly connected to the end of the rotating shaft 53 away from the mounting box 2.

[0025] The controller 3 starts the geared motor 51 to drive the transmission gear 52 to rotate. The rotation of the transmission gear 52 meshes with the driven gear 54, the rotating shaft 53 and the mounting plate 55 to rotate intermittently, thereby sending the nylon bearing body into the press-fit position.

[0026] Among them, the geared motor 51 is electrically connected to the controller 3, and the mounting box 2 has a limit bearing that is compatible with the rotating shaft 53.

[0027] It should be noted that the mounting plate 55 is a solid disc, and a guide rod extending into the mounting box 2 is fixedly connected to the bottom of the mounting plate 55. The mounting box 2 has an annular groove that matches the guide rod, and the guide rod and the annular groove are slidably connected.

[0028] In this embodiment, the positioning device 6 includes two mounting bases 61 fixedly connected to one side of the top of the mounting plate 55, and a bearing fixing base 64 fixedly connected between the two mounting bases 61. An electric push rod 62 is fixedly installed inside each of the two mounting bases 61, and a clamp 63 is fixedly connected to the output end of each of the two electric push rods 62. The controller 3 activates the electric push rods 62 to extend or retract, causing the clamp 63 to move closer to or further away, thereby limiting the nylon bearing body and ensuring accurate positioning of the nylon bearing body. This improves pressing accuracy and prevents the nylon bearing body from deviating from the predetermined track, achieving automatic feeding and precise positioning, effectively improving pressing efficiency and achieving the advantage of high pressing efficiency.

[0029] Among them, four positioning devices 6 are arranged in a ring on the top of the mounting plate 55, and there are several electric push rods 62, all of which are electrically connected to the controller 3.

[0030] In this embodiment, a buffer pressing mechanism 7 extending to the lower surface of the mounting frame 4 is provided on the upper surface. The buffer pressing mechanism 7 includes a hydraulic cylinder 71 fixedly mounted on the upper surface of the mounting frame 4 and extending to the lower surface. A connecting plate 72 is fixedly connected to the output end of the hydraulic cylinder 71, and a fixing plate 73 is fixedly connected to the bottom of the connecting plate 72. A pressing head 74 is fixedly mounted on the bottom of the fixing plate 73, and the pressing head 74 is located on the upper surface of the bearing mounting seat 64. The controller 3 activates the hydraulic cylinder 71 to extend and retract, causing the connecting plate 72, the fixing plate 73, and the pressing head 74 to move downward, thereby performing a pressing action on the nylon bearing.

[0031] The top of the fixed plate 73 is fixedly mounted with an elastic telescopic rod 75, and a spring 76 is fixedly connected between the connecting plate 72 and the fixed plate 73. The end of the elastic telescopic rod 75 away from the fixed plate 73 is fixedly connected to the bottom of the connecting plate 72, and the spring 76 is wrapped around the outside of the elastic telescopic rod 75. By setting the elastic telescopic rod 75 and the spring 76, the impact on the nylon bearing body during the pressing process is reduced, and the deformation and damage of the nylon bearing body are prevented.

[0032] Specifically, a limiting rod 77 extending to the upper surface of the mounting bracket 4 is fixedly connected to the top of the connecting plate 72, and the limiting rod 77 is slidably connected inside the mounting bracket 4. By setting the limiting rod 77, the pressing head 74 is pressed evenly.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, the nylon bearing body is placed inside the four bearing mounting seats 64. The controller 3 activates the electric push rod 62 to extend and retract, causing the clamp 63 to move closer or further away, thereby limiting the nylon bearing body and ensuring accurate positioning. During automatic feeding, the controller 3 activates the reduction motor 51 to drive the transmission gear 52 to rotate. The rotation of the transmission gear 52 meshes with the driven gear 54, the rotating shaft 53, and the mounting plate 55 to rotate intermittently, thereby sending the nylon bearing body into the pressing position. During pressing, the controller 3 activates the hydraulic cylinder 71 to extend and retract, causing the connecting plate 72, the fixing plate 73, and the pressing head 74 to move downward, thereby pressing the nylon bearing. The setting of the limit rod 77 ensures that the pressing head 74 presses evenly, and the setting of the elastic telescopic rod 75 and the spring 76 reduces the impact on the nylon bearing body during the pressing process.
