Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and in particular to a tailstock for a machine tool. Background Technology

[0002] When drilling workpieces, the position of the drill bit on the machine tool tailstock needs to be adjusted according to the drilling location to align the drill bit with the drilling position. Common machine tool tailstocks are usually installed on the machine tool via a movable frame. The horizontal position of the machine tool tailstock can be adjusted, but the vertical position is usually adjusted by inserting shims under the machine tool tailstock, which is not convenient for adjusting the vertical position of the machine tool tailstock.

[0003] To address the aforementioned issues, existing patent publication number CN222133473U, entitled "A Multifunctional Machine Tool Composite Tailstock," proposes a new invention. This invention utilizes a rotating adjusting screw to move the extrusion block horizontally, causing its upper surface to press against the lower surface of the fixing block. The fixing block moves vertically upward, causing the mounting base and the machine tool tailstock body to move vertically upward as well. The mounting base causes a limiting rod to slide on the base, adjusting the vertical position of the machine tool tailstock body. Furthermore, rotating the threaded sleeve moves it on the fixing rod, with the bottom end of the threaded sleeve pressing against the upper surface of the connecting block, thus limiting the positions of the connecting block, mounting base, and machine tool tailstock body. This ensures the stability of the machine tool tailstock body and facilitates adjustment of the drilling position within the machine tool tailstock body.

[0004] However, during use, the machine tool tailstock disclosed in the above patent is prone to relative rotation between the screw and the base due to the vibration of the machine tool, which causes the main body of the machine tool tailstock to shift in the vertical direction, thereby reducing the stability of the machine tool tailstock main body installation. Therefore, it is necessary to propose a tailstock for machine tools to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a tailstock for machine tools to solve the problem mentioned in the background art that, during use, the vibration of the machine tool can easily cause relative rotation between the screw and the base, resulting in displacement of the main body of the tailstock in the vertical direction, thereby reducing the stability of the tailstock installation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tailstock for a machine tool, comprising a base, wherein a mounting seat is provided on the top of the base via an adjustment component, and the machine tool tailstock body is fixedly mounted on the top of the mounting seat;

[0007] The adjustment assembly includes a movable groove inside the base, with two symmetrically distributed screws rotatably arranged inside the movable groove. A linkage assembly is provided between the two screws. Two symmetrically distributed movable rods are slidably arranged inside the movable groove, each movable rod having two threaded holes that cooperate with the screws. The thread paths of the threaded holes inside the two movable rods are opposite. Two symmetrically distributed sliding grooves are provided at the top of the movable groove. Two first connecting seats are fixedly arranged at the top of the movable rods, and the first connecting seats are slidably arranged inside the sliding grooves. Four second connecting seats are fixedly arranged in a matrix evenly distributed at the bottom of the mounting base. Push rods are rotatably arranged between corresponding first and second connecting seats. Two symmetrically distributed adjustment grooves are provided at the top of the movable groove, and the adjustment grooves are located on the side of the sliding grooves. Two screws are fixedly arranged at the top of the movable rods, and a fixing nut is threaded to one end of each screw that moves through the top of the adjustment groove.

[0008] Preferably, the movable groove extends through both the left and right sides of the base, and scales are fixedly installed on both the left and right sides of the base. The end of the movable rod and the end of the base are on the same vertical plane.

[0009] Preferably, the top of the base is fixedly provided with four limiting rods arranged in a matrix evenly, and the interior of the mounting base is provided with limiting holes for the limiting rods to move through.

[0010] Preferably, in the initial state, the second connecting seat is located inside the slide groove, the lower surface of the mounting seat and the upper surface of the base are in contact with each other, and the movable rod is located at the end of the movable groove.

[0011] Preferably, the linkage component includes a pulley, which is fixedly mounted at one end of the screw that movably passes through the front end of the base. A synchronous belt is rotatably arranged between the two pulleys, and a handle is fixedly mounted on the side of one of the pulleys.

[0012] Preferably, both the slide and the adjustment groove extend through the upper surface of the base.

[0013] Preferably, a fixing plate is fixedly installed at both the left and right ends of the bottom of the base.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. After adjusting the mounting base to the required height, this utility model tightens four fixing nuts on the base to fix the lead screw and movable rod, effectively preventing the lead screw from rotating relative to the base under the vibration of the machine tool, thereby ensuring the stability of the machine tool tailstock body installation. This solves the problem that in the use of existing machine tool tailstocks, the vibration of the machine tool can easily cause relative rotation between the lead screw and the base, resulting in vertical displacement of the machine tool tailstock body and reducing the stability of the machine tool tailstock body installation.

[0016] 2. In the initial state of use, the second connecting seat is located inside the slide groove, the lower surface of the mounting seat and the upper surface of the base are in contact with each other, and the movable rod is located at the end of the movable groove, so that the movable rod corresponds to the zero mark of the scale. When adjusting the vertical position of the machine tool tailstock body, turn the handle, and through the setting of the synchronous belt and pulley, drive the two screws to rotate synchronously, thereby driving the two movable rods to move closer to each other. Through the setting of the first connecting seat, the second connecting seat and the push rod, push the mounting seat and the machine tool tailstock body to move upward. After the movable rod is moved to the corresponding scale value of the scale, stop turning the handle. At this time, the mounting seat can be adjusted to the required height, improving the convenience of device adjustment.

[0017] 3. The four second connecting seats and push rods provide balanced support for the mounting base, further improving the stability of the machine tool tailstock body. In addition, the limit rods and limit holes limit the vertical displacement trajectory of the mounting base, ensuring stable vertical displacement of the mounting base and the machine tool tailstock body.

[0024] 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.

[0025] This utility model provides, for example Figures 1-5 The tailstock shown includes a base 1, with fixing plates 2 fixedly installed on the left and right ends of the bottom of the base 1, and a mounting seat 3 installed on the top of the base 1 via an adjustment component. The tailstock body 4 of the machine tool is fixedly installed on the top of the mounting seat 3.

[0026] The adjustment assembly includes a movable groove 5 inside the base 1, with two symmetrically distributed screws 6 rotatably arranged inside the movable groove 5. A linkage assembly is provided between the two screws 6. Two symmetrically distributed movable rods 7 are slidably arranged inside the movable groove 5. Two threaded holes are opened inside the movable rods 7, which cooperate with the screws 6. The thread paths of the threaded holes inside the two movable rods 7 are opposite. Two symmetrically distributed sliding grooves 14 are opened at the top of the movable groove 5. Two first connecting seats 11 are fixedly arranged at the top of the movable rods 7. The first connecting seats 11 are slidably arranged inside the sliding grooves 14. Four second connecting seats 12 are fixedly arranged in a matrix evenly distributed at the bottom of the mounting base 3. Push rods 13 are rotatably arranged between the corresponding first connecting seats 11 and second connecting seats 12. Two symmetrically distributed adjustment grooves 16 are opened at the top of the movable groove 5. Both the sliding grooves 14 and the adjustment grooves 16 penetrate the upper surface of the base 1. The adjustment grooves 16 are located on the side of the sliding grooves 14. Two screws 15 are fixedly arranged at the top of the movable rods 7. The end of the screw 15 that moves through the top of the adjustment groove 16 is threadedly connected to a fixing nut 17.

[0027] The linkage component includes a pulley 8, which is fixedly installed at one end of the screw 6 that moves through the front end of the base 1. A synchronous belt 9 is rotatably installed between the two pulleys 8, and a handle 10 is fixedly installed on the side of one of the pulleys 8.

[0028] Furthermore, the movable groove 5 extends through both the left and right sides of the base 1, and scales 18 are fixedly installed on both the left and right sides of the base 1. The end of the movable rod 7 and the end of the base 1 are on the same vertical plane.

[0029] Specifically, in the initial state of use, the second connecting seat 12 is located inside the slide groove 14, the lower surface of the mounting seat 3 and the upper surface of the base 1 are in contact with each other, and the movable rod 7 is located at the end of the movable groove 5, so that the movable rod 7 corresponds to the zero mark of the scale 18. When adjusting the vertical position of the machine tool tailstock body 4, the handle 10 is turned, and through the setting of the synchronous belt 9 and the pulley 8, the two screws 6 are driven to rotate synchronously, thereby driving the two movable rods 7 to move closer to each other. Through the setting of the first connecting seat 11, the second connecting seat 12 and the push rod 13, the mounting seat 3 and the machine tool tailstock body 4 are pushed to move upward. After the movable rod 7 is moved to the corresponding scale value of the scale 18, the handle 10 is stopped. At this time, the mounting seat 3 can be adjusted to the required height, improving the convenience of device adjustment.

[0030] After adjusting the mounting base 3 to the required height, tighten the four fixing nuts 17 onto the base 1 to fix the lead screw 15 and the movable rod 7. This effectively prevents the lead screw 6 from rotating relative to the base 1 under the vibration of the machine tool, thus ensuring the stability of the machine tool tailstock body 4 during installation. This solves the problem that in the existing machine tool tailstock, the vibration of the machine tool can easily cause relative rotation between the lead screw 6 and the base 1, resulting in displacement of the machine tool tailstock body 4 in the vertical direction and reducing the stability of the machine tool tailstock body 4 during installation.

[0031] In addition, the four second connecting seats 12 and push rods 13 provide balanced support for the mounting seat 3, further improving the stability of the machine tool tailstock body 4 during installation.

[0032] Furthermore, four limiting rods 19 are fixedly installed on the top of the base 1 in a matrix evenly distributed manner. The interior of the mounting base 3 is provided with limiting holes for the limiting rods 19 to move through. By setting the limiting rods 19 and the limiting holes, the vertical displacement trajectory of the mounting base 3 is limited, ensuring the stable vertical displacement of the mounting base 3 and the machine tool tailstock body 4.

[0033] Working principle: In the initial state during use, the second connecting seat 12 is located inside the slide groove 14, the lower surface of the mounting seat 3 and the upper surface of the base 1 are in contact with each other, and the movable rod 7 is located at the end of the movable groove 5, so that the movable rod 7 corresponds to the zero mark of the scale 18. When adjusting the vertical position of the machine tool tailstock body 4, the handle 10 is turned, and through the setting of the synchronous belt 9 and the pulley 8, the two screws 6 are driven to rotate synchronously, thereby driving the two movable rods 7 to move closer to each other. Through the first connecting seat 11, the second connecting seat 12 and the second connecting seat 14 are in contact with each other, the two movable rods 7 are moved closer to each other, and the two movable rods 7 are moved closer to each other, thus driving the two movable rods 7 to move closer to each other, and the two movable rods 7 are moved ... The connection seat 12 and push rod 13 push the mounting seat 3 and the machine tool tailstock body 4 upward. After the movable rod 7 is moved to the scale value of the corresponding scale 18, stop rotating the handle 10. At this time, the mounting seat 3 can be adjusted to the required height. After the mounting seat 3 is adjusted to the required height, tighten the four fixing nuts 17 on the base 1 to fix the lead screw 15 and the movable rod 7, effectively preventing the lead screw 6 from rotating relative to the base 1 under the vibration of the machine tool, thereby ensuring the stability of the machine tool tailstock body 4 installation.
