Description

Technical Field

[0001] This utility model relates to the field of textile machinery processing, specifically to a bearing assembly device for a yarn pressing ring. Background Technology

[0002] In textile machinery processing, the assembly of the pressing ring and the bearing is one of the key processes. The fitting accuracy directly affects the operating stability and service life of the equipment. The traditional assembly method usually adopts an interference fit, which involves manually pressing the bearing into the inner hole of the pressing ring to ensure that the two are tightly connected. This process requires strict control of the pressing force, coaxiality and surface roughness to avoid deformation or damage during the assembly process. The existing assembly process for yarn pressing ring bearings generally suffers from low efficiency. Due to the lack of precise pressure control and positioning guidance, unstable pressing force and coaxiality deviation often occur during the assembly process. This results in poor fit between the bearing and the inner hole of the yarn pressing ring, and micro-deformation or surface scratches are easily caused by uneven local interference. Especially in mass production, manual or semi-automatic pressing methods cannot guarantee process stability. Some bushings have defects such as inner wall roughening, dimensional deviation, or even cracks after pressing, which directly affect the operating accuracy and service life of the components.

[0003] In summary, to improve the process stability and product qualification rate of the yarn pressing ring bearing assembly in textile machinery, it is necessary to solve problems such as inaccurate pressing force control, large coaxiality deviation, and high risk of assembly damage. The interference fit between the bearing and the yarn pressing ring should not only meet the fastening requirements but also avoid bushing deformation or surface damage, thereby ensuring the long-term reliability and precision maintenance of textile equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a bearing assembly device for a yarn pressing ring. By using an electric cylinder for pressing assembly, the intermediate bushing is opened on both sides, thereby locking the bearing. Using an electric cylinder can ensure consistent depth, preventing the opening from being too large and causing the bearing to seize, or too small and causing the bearing to loosen, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing assembly device for a yarn pressing ring, comprising an equipment cabinet, a column fixed to the top of the equipment cabinet, a control panel fixed to the top of the column, an installation component on the equipment cabinet, an electric cylinder on the installation component, a fixing frame on the outside of the electric cylinder, a positioning hole on the fixing frame, a push rod fixed to the output end of the electric cylinder, the electric cylinder being used to drive the push rod to rise and fall, a positioning mechanism on the installation component, a yarn pressing ring body and a bearing body placed on the positioning mechanism, and a support mechanism at the bottom of the equipment cabinet.

[0006] Preferably, the mounting components include a mounting plate fixed to the equipment cabinet, a support plate fixed to the mounting plate, a bracket fixed to the side of the support plate, and a mounting plate fixed to the top of the support plate. The mounting frame is fixedly connected to the mounting plate by bolts.

[0007] Preferably, the positioning mechanism includes a fixing component disposed on a fixing plate and a limiting component disposed on the fixing component. The fixing component is used to install the limiting component, and the limiting component is used to position the yarn pressing ring body and the bearing body.

[0008] Preferably, the fixing seat is fixed on the fixing plate and the fixing groove is opened on the fixing seat, and the fixing seat is fixedly connected to the fixing plate by bolts.

[0009] Preferably, the limiting component includes a positioning plate fixed on a fixed base, a positioning block mounted on the positioning plate, and an insertion hole opened on the positioning plate, wherein the positioning block and the insertion hole are adapted to the pressure ring body.

[0010] Preferably, the support mechanism includes a movable component disposed at the bottom of the equipment cabinet and a lifting component disposed on the movable component. The movable component is used to move the equipment cabinet, and the lifting component is used to support the equipment cabinet.

[0011] Preferably, the movable component includes connecting plates fixed at the four corners of the bottom of the equipment cabinet and casters mounted on the connecting plates, the casters being fixedly connected to the connecting plates by screws.

[0012] Preferably, the lifting assembly includes a support rod disposed on the connecting plate and a washer fixed to the bottom of the support rod, the support rod being threadedly connected to the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention employs an electric cylinder pressing assembly method, which precisely controls the pressing force and pressing depth to ensure optimal fit between the bearing and the inner hole of the pressing ring. The high-precision motion control of the electric cylinder causes the intermediate bushing to deform uniformly, forming a stable double-sided opening structure. This not only reliably holds the bearing in place but also prevents the bearing from jamming or rotating improperly due to excessive opening. Simultaneously, it prevents the bearing from loosening or axial movement due to insufficient opening. This process significantly improves assembly consistency, eliminates the risk of bushing deformation or damage caused by pressure fluctuations in traditional pressing assembly, and reduces the uncertainty of manual operation, providing an effective guarantee for the high-reliability assembly of core components of textile machinery.

[0020] It should be noted that the mounting components, through the combination structure of the fixing plate 41, the support plate 42, the support 43 and the mounting plate 44, jointly undertake the role of positioning, supporting and fixing the electric cylinder 5 and its fixing frame 6 on the equipment cabinet 1, and are the basic mounting platform for the entire pressing actuator.

[0021] Refer to the instruction manual appendix Figures 2 to 4 The positioning mechanism includes a fixing component disposed on the fixing plate 41 and a limiting component disposed on the fixing component. The fixing component is used to install the limiting component, and the limiting component is used to position the pressing ring body 10 and the bearing body 11.

[0022] It should be noted that the positioning mechanism provides the installation position for the limiting component through the fixing component, and the limiting component is directly responsible for receiving and precisely limiting the position of the pressing ring body 10 and the bearing body 11, ensuring that they maintain the required coaxiality and relative position during the pressing process.

[0023] Refer to the instruction manual appendix Figures 2 to 4 The fixing seat 91 is fixed on the fixing plate 41 and the fixing groove 92 is opened on the fixing seat 91. The fixing seat 91 is fixedly connected to the fixing plate 41 by bolts.

[0024] It should be noted that the bolts are passed through the fixing groove 92, and the fixing seat 91 is firmly connected to the fixing plate 41 by the bolts.

[0025] Refer to the instruction manual appendix Figures 2 to 4 The limiting component includes a positioning plate 93 fixed on a fixed base 91, a positioning block 94 mounted on the positioning plate 93, and an insertion hole 95 opened on the positioning plate 93. The positioning block 94 and the insertion hole 95 are adapted to the pressing ring body 10.

[0026] It should be noted that the limiting component directly cooperates with the yarn pressing ring body 10 through the specific structural combination of the positioning plate 93, the positioning block 94 and the insertion hole 95. By utilizing the shape constraints of the positioning block 94 and the insertion hole 95, the precise positioning of the yarn pressing ring body 10 and the bearing body 11 can be achieved.

[0027] Refer to the instruction manual appendix Figure 5 The support mechanism includes a movable component located at the bottom of the equipment cabinet 1 and a lifting component located on the movable component. The movable component is used to move the equipment cabinet 1, and the lifting component is used to support the equipment cabinet 1.

[0028] It should be noted that the support mechanism enables the convenient movement of the entire device through the moving components, and provides stable support after the device is in place through the lifting components, preventing shaking or displacement during the pressing operation.

[0029] Refer to the instruction manual appendix Figure 5The movable component includes a connecting plate 121 fixed at the four corners of the bottom of the equipment cabinet 1 and casters 122 mounted on the connecting plate 121. The casters 122 are fixedly connected to the connecting plate 121 by screws.

[0030] It should be noted that the moving component, through the structure of the connecting plate 121 and the casters 122, enables the equipment cabinet 1 to be easily pushed or pulled, realizing the transfer of the device between different working positions.

[0031] Refer to the instruction manual appendix Figure 5 The lifting assembly includes a support rod 123 mounted on a connecting plate 121 and a gasket 124 fixed to the bottom of the support rod 123. The support rod 123 is threadedly connected to the connecting plate 121.

[0032] It should be noted that the lifting assembly is connected to the connecting plate 121 via a threaded connection between the support rod 123 and the connecting plate 121, so that the height of the support rod 123 relative to the connecting plate 121 and the equipment cabinet 1 can be adjusted when the support rod 123 is rotated. The grounding area is increased by the shim 124, so that the entire equipment cabinet 1 can be stably supported after the adjustment is in place, thus offsetting the mobility of the caster wheel 122.

[0033] Working principle: The operator first places the pressing ring body 10 and the bearing body 11 on the positioning plate 93, using the positioning block 94 and the insertion hole 95 to ensure precise alignment. Then, the operator starts the equipment via the control panel 3. After receiving the command, the electric cylinder 5 drives the push rod 8 at its output end to move downward. The push rod 8 precisely aligns with and presses against the bearing body 11. Under the controllable pressing force and depth, the bearing body 11 is smoothly pressed into the inner hole of the pressing ring body 10, causing the intermediate bushing of the pressing ring body 10 to produce an appropriate and uniform pressure. The deformation of the bearing body 11 reliably locks and fixes it, avoiding both excessive deformation that could cause the bearing body 11 to jam and insufficient deformation that could cause it to loosen. After pressing, the electric cylinder 5 automatically drives the push rod 8 to rise and reset. The casters 122 at the bottom of the device facilitate overall movement. In the working position, the support rod 123 on the rotating connecting plate 121 causes the pad 124 to descend and contact the ground, supporting the equipment cabinet 1, thereby offsetting the movement of the casters 122 and ensuring the stability of the pressing process.

[0034] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art.
