Abstract
Description
Technical Field
[0001] This utility model relates to the field of servo tailstock technology, and in particular to a servo tailstock for machining slender shaft-type workpieces. Background Technology
[0002] The GX500LY turning-milling-grinding composite machine tool is an advanced machining equipment that integrates the functions of a lathe, milling machine, and grinding machine. It can complete multiple machining processes such as turning, milling, grinding, drilling, and tapping in a single setup, greatly improving production efficiency and machining accuracy. This machine tool has a structure with high rigidity, high stability, high flexibility, and a good degree of intelligence and automation, making it suitable for machining parts with complex shapes and high precision requirements.
[0003] The GX500LY milling and turning machine tool is widely used in aerospace, automotive manufacturing, and energy equipment industries, and is particularly suitable for machining large and complex parts. It meets the demands for high precision and high efficiency machining, making it an indispensable piece of equipment in modern manufacturing.
[0004] The key components of the GX500LY milling and turning CNC machine tool include the high-stability bed, tailstock, saddle, slide, high-precision spindle, fixture, and tool post structure. The design of these components directly affects the machine tool's performance and machining accuracy.
[0005] As described in announcement number CN219093654U, a servo tailstock for a gear grinding machine includes a center mounting base, a center mounted on the center mounting base, two parallel guide rails, and a slider mounted on the guide rails. A center mounting base and an adapter plate are mounted on the upper surface of the slider. A servo motor and a lead screw are mounted on the adapter plate. One end of the lead screw is installed inside the center mounting base, and the other end is fitted with a limit end cap and a buffer pad. A drive pulley is mounted on the shaft of the servo motor, and a synchronous pulley is mounted on the lead screw. A belt is fitted between the drive pulley and the synchronous pulley. This utility model eliminates the time required for adjusting the busbar accuracy after the tailstock moves, significantly improving changeover efficiency. The clamping force can be adjusted according to workpieces of different weights. Through lead screw transmission and belt deceleration, the clamping force of the tailstock center is increased. After the travel speed is reduced, the clamping speed is controllable.
[0006] This patent can significantly improve changeover efficiency; the clamping force can be adjusted according to workpieces of different weights. However, the back cover of existing servo tailstocks generally uses multiple sets of bolts for fastening. When a fault occurs inside the tailstock and needs to be repaired, the operator needs to remove these bolts one by one, which is a cumbersome and time-consuming process.
[0007] Therefore, we propose a novel servo tailstock for machining slender shaft-type workpieces. Utility Model Content

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0030] Example 1, such as Figure 1 - Figure 4 This utility model provides a servo tailstock for machining slender shaft workpieces, including a main body 1. A slide rail 2 is mounted on the surface of the main body 1. A convenient disassembly and maintenance component 3 is provided on the surface of the slide rail 2. The convenient disassembly and maintenance component 3 includes a servo tailstock main body 301. A rear cover 302 is provided at the rear end of the servo tailstock main body 301. A locking block 303 is fixedly connected to both the upper and lower surfaces of the rear cover 302. A slot 304 is connected to the surface of the locking block 303. A fixing block 305 is connected to both the upper and lower ends of the servo tailstock main body 301. Two sets of springs 306 are provided inside the fixing block 305. A plug rod 307 is inserted into the inside of each set of springs 306. The top of the two sets of plug rods 307 is fixedly connected to a handle 308, the bottom of the two sets of plug rods 307 is connected to a push plate 309, the bottom of the push plate 309 is connected to a plug block 310, the bottom of the fixing block 305 is provided with a slot 311, the surface of the plug block 310 is provided with a bevel, the position and size of the plug block 310 match the position and size of the slot 304, the plug block 310 and the slot 304 form an insertion connection, the locking block 303 and the slot 311 form a locking connection, the surface of the back cover 302 is provided with heat dissipation holes, the outer surface of the push plate 309 is in contact with the inner wall of the fixing block 305, and the push plate 309 and the spring 306 form an elastic structure.
[0031] The effect achieved by the entire embodiment 1 is that when the servo tailstock body 301 malfunctions after prolonged use and requires disassembly and repair, both sets of handles 308 can be grabbed simultaneously and pulled upwards and downwards. This causes the handles 308 to drive the push plate 309 upwards via the insert rod 307, compressing the spring 306 and causing the insert block 310 to be pulled out of the slot 304. Then, the rear cover 302 is pulled outwards, causing the retaining block 303 of the rear cover 302 to be pulled out of the retaining groove 311, thus completing the disassembly. After that, the servo tailstock body 301 can be repaired. After the servo tailstock body 301 is repaired, the locking block 303 of the rear cover 302 can be aligned with the slot 311 and pushed towards the insertion block 310. When the angled opening of the insertion block 310 is squeezed, it will retract upward. When the locking block 303 is fully inserted into the slot 311, the spring 306 will push the push plate 309 through its own elasticity to drive the insertion block 310 into the slot 304 for fixing. This avoids the problem of the existing rear cover 302 being fixed with multiple sets of bolts, which is very inconvenient during disassembly and repair, and improves the convenience of repairing the servo tailstock body 301.
[0032] Example 2, as Figure 1 and Figure 5 The bottom of the servo tailstock body 301 is provided with a mounting and fixing component 4, which includes a movable base 401. Limit frames 402 are connected to both sides of the movable base 401. A groove 409 is formed on the top of the movable base 401. A bidirectional screw 403 is inserted into the movable base 401. One end of the bidirectional screw 403 is connected to a bearing body 404, and the other end is connected to a throttle 405. Two sets of moving blocks 406 are symmetrically connected to the surface of the bidirectional screw 403. Threaded holes 407 are formed inside the moving blocks 406, and a moving plate 408 is connected to the top of the moving blocks 406. Positioning blocks 410 are fixedly connected to both sides of the bottom. Positioning slots 411 are opened inside the positioning blocks 410. A bearing sleeve 412 is set at the center of the surface of the bidirectional screw 403. The bidirectional screw 403 is electrically connected to the bearing body 404 and the bearing sleeve 412. The bidirectional screw 403 is threadedly connected to the moving block 406 through the threaded hole 407. The position and size of the moving plate 408 match the position and size of the positioning slot 411. The positioning slots 411 are fixedly connected to each other. The limiting frame 402 is U-shaped. The inner wall of the limiting frame 402 is in contact with the outer surface of the moving plate 408.
[0033] The effect achieved by the entire embodiment 2 is that when the movable base 401 needs maintenance, the handle 405 can be rotated forward, so that the handle 405 can drive the bidirectional screw 403 to rotate forward. At the same time, the bidirectional screw 403 will also rotate with the two sets of movable blocks 406 through the threaded hole 407. In this way, the two sets of movable blocks 406 will move to both sides at the same time through the threaded rotation. As the movable blocks 406 move, they will also drive the two sets of movable blocks 406 to move to both sides, so that the two sets of movable blocks 406 can be pulled out from the positioning groove 411. The set limiting frame 402 can limit the movable blocks 406. When the movable blocks 406 move to the limiting frame After reaching position 402, stop rotating the handle 405. Then, pull the servo tailstock body 301 upwards to remove the positioning block 410 at the bottom of the servo tailstock body 301 from the groove 409 to complete disassembly. After that, the moving base 401 can be maintained. After maintenance, the positioning block 410 at the bottom of the servo tailstock body 301 can be inserted into the groove 409. Then, the handle 405 can be rotated in the opposite direction to move the two sets of moving blocks 406 inwards at the same time, and drive the moving plate 408 into the positioning slot 411 to fix the servo tailstock body 301. This avoids the problem that the existing servo tailstock body 301 is inconvenient to disassemble and the moving base 401 is inconvenient to maintain.
[0034] Working principle: When the servo tailstock body 301 malfunctions after prolonged use and requires repair, the insert 310 can be pulled out of the slot 304 by pulling the handle 308. Then, the rear cover 302 can be directly disassembled and repaired. After repair, the rear cover 302 can be pushed directly onto the servo tailstock body 301, and the spring 306 completes the quick installation of the rear cover 302. This avoids the problem of the existing rear cover 302 being fixed with multiple sets of bolts, which is very inconvenient during disassembly and repair, thus improving the convenience of repairing the servo tailstock body 301. When the movable base 401 has been used for a long time, the movable plate 408 can be pulled out of the positioning slot 411 by turning the handle 405. Then, the servo tailstock body 301 can be removed from the surface of the movable base 401 for routine maintenance. This avoids the problem of the existing servo tailstock body 301 being inconvenient to disassemble, which makes the maintenance of the movable base 401 more difficult.
[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
