Description

Technical Field

[0001] This utility model relates to the field of textile bearing housing processing technology, specifically a clamping tool for processing textile bearing housings. Background Technology

[0002] Bearing housings are components used to fix and support bearings, fixing the outer ring of the bearing while the inner ring rotates with the rotating shaft. Textile bearing housings are an application of bearing housings in the field of textile machinery. In addition to having the functions of general bearing housings, they also need to adapt to the high-speed, high-precision, high-reliability, and dusty working environment of textile machinery.

[0003] An investigation revealed that a utility model patent (publication number: CN219562776U) discloses a clamping fixture for bearing housing production and processing. The fixture includes a base with symmetrically arranged sliding grooves on its upper surface. A slider is positioned between the sliding groove and a limiting block. The limiting block is movably connected to the sliding groove via the slider. A hydraulic cylinder is fixedly mounted on the upper end of the limiting block. A through groove is formed in the center of the front surface of the limiting block, and a hydraulic rod is threaded through the center of the hydraulic cylinder. The advantages of this utility model are: during the turning of the adjusting screw, the adjusting screw drives the slider to move in the sliding groove, thereby driving the limiting block to position and clamp the bearing housing placed on the base. When the hydraulic cylinder operates, the hydraulic rod presses against a movable plate. The movable plate, guided by a guide block in a guide groove, can move up and down in the through groove on the limiting block. During the movement of the movable plate, a pressure plate is driven to press the upper end of the bearing housing. The application of this fixture effectively avoids the aforementioned problems and improves the practicality of the equipment.

[0004] Although the aforementioned patent, through the configuration of the above-mentioned structure, allows the adjusting screw to move the slider in the slide groove during the turning of the adjusting screw, thereby driving the limiting block to position and clamp the bearing seat placed on the base, the hydraulic cylinder to operate, the hydraulic rod to press the movable plate, and the movable plate to move up and down in the through groove opened on the limiting block by the guiding action of the guide block in the guide groove, and the movable plate to drive the pressure plate to press the upper end of the bearing seat during the movement of the movable plate, the clamping lacks strong adsorption during the processing. It is easily affected by cutting force, vibration and workpiece thermal expansion, resulting in micro-displacement of the workpiece in the fixture, which affects the processing accuracy. When the clamping force is insufficient, the tool is subjected to uneven force, which easily produces cutting force fluctuations, resulting in decreased surface roughness, accelerated tool wear and accumulated processing path errors.

[0005] Therefore, this utility model provides a clamping fixture for processing textile bearing housings to solve the above problems. Utility Model Content

[0017] 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.

[0018] This utility model provides a clamping fixture for processing textile bearing housings, such as... Figures 1-5As shown, the clamping fixture for processing textile bearing seats includes a connecting plate 1, a support rod 2 fixedly connected to the upper surface of the connecting plate 1, a disc 3 fixedly connected to one end of the support rod 2, a clamping mechanism fixedly installed on the back of the disc 3, and a base plate 4 fixedly connected to the bottom of the connecting plate 1 around the perimeter via connecting rods, and an adsorption mechanism fixedly installed on the upper surface of the base plate 4. The adsorption mechanism includes a pump 5, the bottom of which is fixedly mounted on the upper surface of the base plate 4. One end of the pump 5 is fixedly connected to a transmission pipe 6, and the other end of the transmission pipe 6 is fixedly connected to an annular pipe 7. A clamping ring 8 is clamped to the inner side of the annular pipe 7 through a conduit. An adsorption groove 9 is opened on the inner side wall of the clamping ring 8. After the textile bearing seat is clamped, the adsorption mechanism is used to further strengthen the adsorption. The adsorption mechanism provides additional constraints on the basis of mechanical clamping, reducing the micro-displacement of the workpiece under the action of cutting force, vibration and thermal expansion, thereby improving the consistency of processing and repeatability of positioning accuracy. It is more firmly fixed and can effectively prevent the workpiece from displacement, falling or mis-installation under high impact or high cutting force, reducing operational risks.

[0019] The clamping mechanism includes a servo motor 10, the outer surface of which is fixedly mounted on the back of the disc 3. The output end of the servo motor 10 is splinedly connected to a gear disk A 11, and the outer surface of the gear disk A 11 meshes with a gear disk B 12. The clamping mechanism can provide more positioning support points, reduce the offset caused by single-point force, avoid excessive local force through multi-point or group clamping, improve overall rigidity, reduce the micro-movement of the workpiece during processing, and clamp it according to the textile bearing seat. The stable clamping reduces vibration coupling during processing, improves the stability of the tool force, and thus improves surface roughness and processing consistency.

[0020] The surface of the disc 3 is provided with a groove, and a slider 13 is slidably connected inside the groove. One end of the slider 13 is fixedly connected to a spring 14, and one end of the spring 14 is fixedly connected to the inner wall of the groove. The spring 14 can play a positioning and buffering role. When the slider 13 moves inward and engages, it can buffer the clamping force of the bearing seat.

[0021] The other end of the slider 13 is fixedly connected to an outer support block 15. The inner side wall of the outer support block 15 is fixedly connected to an insert block 16. The surfaces of the insert block 16 and the slider 13 are both provided with threaded holes. The threaded holes are connected to a fixing bolt 17, and the outer surface of the fixing bolt 17 is connected to a nut 18. The fixing bolt 17 and the nut 18 are used to fix and securely install the insert block 16 inside the slider 13.

[0022] A limiting rod 19 is fixedly connected to the front of the slider 13. An anti-slip sleeve is fixedly connected to the outer surface of the limiting rod 19. Adding an anti-slip sleeve to the outside of the limiting rod 19 can achieve the anti-slip effect and prevent the limiting rod 19 from falling out of the B gear disk 12.

[0023] The surface of gear disk 12 is provided with an arc-shaped groove. The inside of the arc-shaped groove is adapted to slide and engage with the limiting rod 19. When the limiting rod 19 slides in the arc-shaped groove, it can drive the slider 13 to move in the groove, which facilitates the movement of the outer support block 15.

[0024] Specifically, the outer part of the bearing housing is placed inside the clamping ring 8. The servo motor 10 is started. When the servo motor 10 rotates, it drives the A gear disk 11 to rotate. The A gear disk 11 drives the B gear disk 12 to rotate. When the B gear disk 12 rotates, it moves the limiting rod 19 through the arc groove on its surface. When the limiting rod 19 moves, it drives the slider 13 and the outer support block 15 to expand outward or contract inward. The outer support block 15 drives the clamping ring 8 to move. The clamping ring 8 is used to clamp and fix the bearing housing. After clamping and fixing, the pump 5 is started. The pump 5 draws air in the annular pipe 7 through the transmission pipe 6. The bearing housing is firmly adsorbed through the adsorption groove 9. Subsequently, before clamping, the shape of the clamping ring is different. When it is necessary to adjust the clamping point of the clamping ring 8, the nut 18 and the fixing bolt 17 are turned to separate the fixing bolt 17 from the insert block 16. The insert block 16 is pulled out from the slider 13 to facilitate the disassembly of the clamping ring 8.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
