Description

Technical Field

[0001] This utility model relates to the field of lathe tailstock technology, specifically to a tailstock structure for a CNC horizontal lathe. Background Technology

[0002] CNC lathes can automate the cutting and machining of workpieces, featuring high precision, high efficiency, and good repeatability, and are widely used in manufacturing. A horizontal CNC lathe is a type of lathe controlled by a computer numerical control system, with its spindle arranged horizontally. The tailstock structure of a horizontal CNC lathe is usually located at the right end of the lathe bed, used to support one end of a long workpiece to prevent bending or vibration during machining. The tailstock can move along the bed guideways and is secured to the workpiece using centers or drilling fixtures, thus ensuring machining stability and accuracy.

[0003] However, current tailstock structures require frequent changes of drilling fixtures to meet different cutting requirements, which not only increases operational complexity but also significantly affects workpiece machining speed. Therefore, there is an urgent need to design a tailstock structure for CNC horizontal lathes.

[0004] For example, Chinese patent CN222175963U discloses a multi-functional seat structure for an adjustable lathe tailstock, including a base, a tailstock body on the top of the base, a pin inside the tailstock body, and an adjustment mechanism inside the base. The adjustment mechanism includes a first motor, a drive gear, a driven gear, an adjustment screw, a screw sleeve, a slider, a first telescopic cylinder, and a second telescopic cylinder.

[0005] Although the adjustable lathe tailstock uses a multi-functional seat structure to adjust the tailstock height and center length, frequent changes of the center or drilling fixture are required when facing different cutting needs. This not only increases the complexity of operation but also significantly affects the workpiece machining rate.

[0006] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

A rotating rod is connected to the outer side of one set of sliding blocks, and a rotating rod is connected to the bottom end of the rotating rod to cooperate with another set of sliding blocks. Support blocks that cooperate with the tailstock body are symmetrically arranged on the outer side of the rotating rod.

[0011] Furthermore, to facilitate easy switching between suitable drill chucks when facing different cutting requirements, reduce the complexity of frequent center or drill chuck changes, and significantly improve workpiece processing speed, the switching mechanism includes a housing located at one end of a moving rod. A hollow column is located in the middle of the bottom and top of the housing, with a first track groove at the top of the hollow column. A spring is installed inside the hollow column, with a pressing post at the top of the spring. A rotating platform that mates with the housing is located on the outer side of the pressing post, and several drill chucks are located on the outer side of the rotating platform. An annular groove that mates with the rotating platform is located on the inner wall of the housing. A limiting protrusion that mates with the rotating platform is located on one side of the pressing post. An annular groove that mates with the annular groove is located on the outer side of the rotating platform. Several vertical slides that mate with the limiting protrusion are located in the middle of the top of the rotating platform, and second track grooves that mate with the first track groove are located at the bottom of the vertical slides.

[0025] According to an embodiment of the present invention, a tailstock structure for a CNC horizontal lathe is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, the tailstock structure of the CNC horizontal lathe according to an embodiment of the present invention includes a tailstock body 1, a telescopic protective shell 2 is provided at the bottom end of the tailstock body 1, a slide 3 is provided at the bottom end of the telescopic protective shell 2, and the slide 3 and the tailstock body 1 are connected by a lifting mechanism 4; a fixed seat 5 is provided at one end of the tailstock body 1, a cylinder 6 is provided on one side of the fixed seat 5, a push rod 7 is provided on the output shaft of the cylinder 6, a bushing 8 is provided on the outside of the push rod 7, a moving rod 9 is provided at the end of the bushing 8 away from the push rod 7, a switching mechanism 10 is provided at one end of the moving rod 9, and a plurality of drill chucks 11 are provided on the outside of the switching mechanism 10.

[0027] By utilizing the above technical solutions, this utility model, through the coordinated action of the tailstock body 1, slide 3, lifting mechanism 4, switching mechanism 10, and drill chuck 11, allows for adjustment of the tailstock height according to different cutting requirements, while also facilitating convenient drill bit switching, reducing operational complexity, and increasing workpiece processing speed. The coordinated action of the tailstock body 1, slide 3, and lifting mechanism 4 allows operators to adjust the tailstock height and flexibly adapt to the processing requirements of different products, improving processing efficiency and accuracy. The coordinated action of the switching mechanism 10 and drill chuck 11 allows for easy switching of the appropriate drill chuck 11 when facing different cutting requirements, reducing the complexity of frequent center or drill chuck 11 changes and significantly improving workpiece processing speed.

[0028] It should be explained that the telescopic protective case 2 is usually made of durable materials such as plastic, rubber, metal or synthetic fiber. The telescopic protective case 2 is usually designed to be corrugated or foldable so that it can extend and retract freely with the movement of the equipment. The telescopic protective case 2 is existing technology and will not be described in detail here.

[0029] In one embodiment, for the tailstock 1, slide 3, and lifting mechanism 4 described above, the tailstock 1 has limiting grooves 101 on both sides of its bottom end that cooperate with the slide 3; the slide 3 has symmetrically arranged limiting posts 301 on both sides of its top end that cooperate with the limiting grooves 101, and each limiting post 301 has a scale line 302 on both sides; the lifting mechanism 4 includes a motor 401 disposed on the top end of the slide 3, the output end of the motor 401 is provided with a rotating shaft 402, the two ends of the rotating shaft 402 are symmetrically arranged with support blocks 403 that cooperate with the slide 3, and both ends of the rotating shaft 402 are provided with external threads. The threads 404 at both ends of the rotating shaft 402 are opposite in direction. Sliding blocks 405 are symmetrically arranged at both ends of the external threads 404. A rotating rod 406 is connected to the outer side of one set of sliding blocks 405. A rotating rod 407 that cooperates with another set of sliding blocks 405 is connected to the bottom end of the rotating rod 406. A support block 408 that cooperates with the tailstock body 1 is symmetrically arranged on the outer side of the rotating rod 406. Thus, the operator can adjust the tailstock height and flexibly adapt to the processing requirements of different products according to the cutting processing needs, thereby improving the processing efficiency and accuracy of the products.

[0030] The working principle of the tailstock body 1, slide 3, and lifting mechanism 4 is as follows: In the initial state, the operator adjusts the tailstock height according to the processing requirements. Under the action of the external controller, the motor 401 is controlled and started. Under the action of the output shaft of the motor 401, the rotating shaft 402 is driven to rotate. Under the action of the support block 403, the rotating shaft 402 rotates stably. During the rotation of the rotating shaft 402, the sliding block 405 is driven to move. The sliding block 405 is respectively sleeved at the opposite positions of the thread direction of the external threads 404 at both ends of the rotating shaft 402. During the rotation of the rotating shaft 402, the sliding block 405 will be driven to move. Simultaneously, the rotating shaft 402 moves towards each other in the horizontal direction. During the movement of the sliding block 405, one end of the rotating rod 406 and one end of the rotating rod 407 move towards each other respectively. Under the support of the support block 408, the tailstock 1 moves vertically as one end of the rotating rod 406 and one end of the rotating rod 407 move towards each other. With the cooperation of the limiting groove 101 and the limiting post 301, the tailstock 1 moves stably in the vertical direction, realizing the position adjustment of the tailstock 1. At the same time, the operator can observe the adjustment height of the tailstock 1 through the scale line 302.

[0031] In one embodiment, the switching mechanism 10 includes a housing 1001 disposed at one end of the moving rod 9. A hollow column 1002 is disposed at the middle of the bottom top of the inner part of the housing 1001. A track groove 1003 is formed at the top of the hollow column 1002. A spring 1004 is disposed inside the hollow column 1002. A pressing column 1005 is disposed at the top of the spring 1004. A rotating platform 1006 that cooperates with the housing 1001 is disposed on the outer side of the pressing column 1005. A plurality of drill chucks 11 are disposed on the outer side of the rotating platform 1006. An annular groove 100 that cooperates with the rotating platform 1006 is formed on the inner wall of the housing 1001. 11; A limiting protrusion 10051 that cooperates with the rotating table 1006 is provided on one side of the pressing column 1005; A ring 10061 that cooperates with the annular groove 10011 is provided on the outer side of the rotating table 1006; Several vertical slides 10062 that cooperate with the limiting protrusion 10051 are provided at the top center of the rotating table 1006; and Track grooves 10063 that cooperate with track groove 1003 are provided at the bottom of the several vertical slides 10062. Thus, when facing different cutting processing requirements, it is easy to switch the appropriate drill chuck 11, reduce the complexity of frequently changing the center or drill chuck 11, and significantly improve the processing speed of the workpiece.

[0032] The working principle of the switching mechanism 10 is as follows: In the initial state, the operator switches the drill chuck 11 according to the cutting requirements. The operator applies force to the pressing column 1005, and the pressing column 1005 slides on the vertical slide rail 10062 under the force. The movement of the pressing column 1005 drives the limiting protrusion 10051 to move on the vertical slide rail 10062. Under the action of the first track groove 1003 and the second track groove 10063, the track slide is formed. The limiting protrusion 10051 moves from the vertical slide rail 10062 to the lowest point of the track slide. Then the operator releases the pressing column 1005. The force of the pressing column 1005, under the action of the elastic force of the spring 1004, causes the spring 1004 to rebound and apply a reverse force to the pressing column 1005. The movement of the pressing column 1005 drives the movement of the limiting protrusion 10051. At this time, the lowest point of the track slide of the limiting protrusion 10051 moves to the next highest point of the track slide. During the movement of the limiting protrusion 10051, the rotating table 1006 is driven to rotate. Under the cooperation of the annular groove 10011 and the annular ring 10061, the rotating table 1006 rotates stably. The rotation of the rotating table 1006 drives the drill chuck 11 to switch.

[0033] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0034] In practical applications, in the initial state, the drill chuck 11 is switched according to the cutting requirements. The operator applies force to the pressing column 1005, which drives the rotating table 1006 to rotate, thus switching the drill chuck 11 (the specific working principle of the switching mechanism 10 is as described above). After the drill bit switching is completed, the motor 401 is controlled and started by the external controller. Under the action of the output shaft of the motor 401, the tailstock 1 is moved vertically (the tailstock 1, slide 3, and lifting mechanism 4 are specifically...). As described above, the operator observes the adjustment height of the tailstock 1 through the scale line 302. When the drill bit is in the appropriate machining position, the slide 3 is moved to the appropriate distance on the CNC horizontal lathe. Under the action of the external controller, the cylinder 6 is controlled and started. Under the action of the output end of the cylinder 6, the push rod 7 is driven to move. The movement of the push rod 7 drives the movement rod 9 to move. Under the action of the bushing 8, the movement rod 9 moves stably. The movement of the movement rod 9 drives the drill chuck 11 to move and stamp the product, thus realizing the processing of the product.

[0035] Furthermore, the tailstock structure of this CNC horizontal lathe can not only improve the machining speed by changing the tailstock structure of the horizontal CNC lathe, but also adapt to other types of lathes by changing the parameters of the slide 3 according to different parameters, and make tailstock structure modifications according to the characteristics of other lathes, thereby improving the machining speed and quality of the workpiece.

[0036] In summary, by utilizing the above-mentioned technical solution of this utility model, the tailstock height can be adjusted according to different cutting requirements through the coordinated action of the tailstock body 1, slide 3, lifting mechanism 4, switching mechanism 10, and drill chuck 11. Simultaneously, drill bits can be easily switched, reducing operational complexity and increasing workpiece processing speed. With the coordinated action of the tailstock body 1, slide 3, and lifting mechanism 4, operators can adjust the tailstock height and flexibly adapt to the processing requirements of different products according to cutting needs, improving product processing efficiency and accuracy. With the coordinated action of the switching mechanism 10 and drill chuck 11, the appropriate drill chuck 11 can be easily switched when facing different cutting requirements, reducing the complexity of frequent changes to the center or drill chuck 11, and significantly improving workpiece processing speed.
