Description

Technical Field

[0001] The utility model relates to the field of machine tool chucks, in particular to a laser surface treatment machine tool chuck. Background Art

[0002] Laser surface treatment machine tools are equipment that processes the surface of workpieces and are widely used in the processing of various regular and irregular objects. The chuck is a mechanical device used to clamp the workpiece on the machine tool. It uses the radial movement of the movable jaws evenly distributed on the chuck body to clamp and position the workpiece. The chuck is generally composed of a chuck body, movable jaws and a jaw drive mechanism. The chuck body has a minimum diameter of 65 mm and a maximum of 1500 mm, with a through hole in the center to allow the workpiece or bar to pass through. The chuck is usually installed on lathes, external cylindrical grinders and internal cylindrical grinders, and can also be used in conjunction with various indexing devices for milling machines and drilling machines.

[0003] In the prior art, a three-jaw chuck includes a main body with a plurality of ring-arranged jaws slidably connected to the main body. The jaws can slide along the slide grooves provided on the main body so that the plurality of jaws can approach or move away from each other, thereby achieving clamping or loosening of the workpiece. In order to facilitate clamping the workpiece, a linkage mechanism such as a gear set is provided on the main body. The linkage mechanism can drive the movement of the plurality of jaws at the same time, so that the plurality of jaws can be moved toward the workpiece at one time, thereby quickly completing the clamping of the workpiece.

[0004] However, in the existing clamping mode, since the position of a single jaw is restricted by the linkage mechanism and cannot be adjusted individually, it is easy to cause some jaws to fail to form effective contact with the workpiece, resulting in poor clamping effect on the workpiece or even clamping failure. In addition, the existing jaws can only stably clamp the workpiece shape that matches the jaws, and cannot adjust the jaws accordingly according to the shape of the workpiece to achieve stable clamping of workpieces with various different rules. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a laser surface treatment machine tool chuck to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a laser surface treatment machine tool chuck, comprising a chuck body, a side wall of one side of the chuck body having a wrench adjustment square hole, three movable sliders movably installed on the chuck body at equal intervals along the circumference, and an adjustment assembly is provided inside the movable slider, a mounting block is fixedly installed on the top of the adjustment assembly, and a cross-shaped groove is provided on the top of the mounting block, a cross-shaped connecting block is detachably installed on the top of the mounting block through the cross-shaped groove, and a movable clamping claw is fixedly installed on the top of the cross-shaped connecting block.

[0007] By adopting the above technical solution, the position of a single movable jaw can be adjusted individually through the setting of the adjustment component. When clamping a special-shaped workpiece, the jaw can form effective contact with the workpiece, thereby improving the clamping effect of the workpiece. In addition, by setting the telescopic isolation belt, the inside of the movable groove can be shielded during the movement of the threaded sleeve, thereby preventing waste chips from falling into the movable groove during laser processing of the workpiece clamped by the chuck, thereby affecting the use of the adjustment screw.

[0008] The utility model is further configured as follows: the adjusting component includes: a movable groove, the movable groove is opened inside the movable slider, an adjusting screw is installed with a horizontal rotation inside the movable groove, and one end of the adjusting screw extends to the outside of the movable slider, a threaded sleeve is threadedly installed on the surface of the adjusting screw, and the upper end of the threaded sleeve extends to the outside of the movable slider, a guide rod is provided with an internal movable penetration at the upper end of the adjusting screw, and the two ends of the guide rod are fixedly connected to the inner wall of the movable groove, and the bottom of the mounting block is fixedly connected to the middle position of the top of the threaded sleeve.

[0009] By adopting the above technical solution, when clamping a special-shaped workpiece, first rotate the knob at one end of the adjusting screw to rotate the adjusting screw. At this time, the threaded sleeve installed on the surface of the adjusting screw moves horizontally under the guidance of the guide rod, thereby adjusting the position of the movable claw above the single threaded sleeve. By adjusting the position of a single movable claw separately, the claw can form effective contact with the workpiece when clamping the special-shaped workpiece, thereby improving the clamping effect of the workpiece.

[0010] The utility model is further configured such that telescopic isolation belts are fixedly installed on both sides of the inner wall of the upper end of the movable groove, and one end of the telescopic isolation belt is fixedly connected to the outer wall of one side of the threaded sleeve.

[0011] By adopting the above technical solution, the interior of the telescopic isolation belt is connected to the isolation belt through the clockwork spring, so that the isolation belt is kept taut, thereby preventing waste chips from falling into the movable groove during laser processing of the workpiece clamped in the chuck, thereby affecting the use of the adjusting screw.

[0012] The utility model is further configured such that bearings are provided at both ends of the adjusting screw, and the inner ring of the bearing is fixedly connected to the surface of the adjusting screw, and the outer ring of the bearing is fixedly connected to the inside of the movable slider.

[0013] By adopting the above technical solution and setting the bearing, the stability of the rotation of the adjusting screw is improved.

[0014] The present invention is further configured such that a knob is fixedly connected to one end of the adjusting screw rod, and a plurality of grooves are provided on the outer wall of the knob at equal intervals along the circumference.

[0015] By adopting the above technical solution and setting the groove on the outer wall of the knob, when the knob at one end of the adjusting screw is rotated, the friction between the hand and the knob can be increased, which facilitates the rotation of the adjusting screw.

[0017] By adopting the above technical solution, when the corresponding clamping jaw needs to be adjusted according to the shape of the clamped workpiece, the hexagonal nut is rotated with a wrench to unscrew one end of the hexagonal nut from the inside of the threaded hole, and then the position of the clamping jaw on the movable clamping jaw on the top of the cross-shaped connecting block is adjusted. After that, one end of the hexagonal nut is screwed into the adjusted threaded hole, which facilitates adjustment of the adaptive clamping according to the shape of the clamped workpiece, thereby further improving the applicability of the chuck.

[0018] The utility model is further configured such that rectangular clamping jaws, arc-shaped clamping jaws, conical clamping jaws and hard clamping jaws are sequentially arranged around the movable clamping jaws, and anti-slip grooves are provided on the surfaces of the rectangular clamping jaws, arc-shaped clamping jaws, conical clamping jaws and hard clamping jaws.

[0019] By adopting the above technical solution, by setting different types of jaws around the movable jaw, when clamping the workpiece, the most suitable jaw type can be determined according to the specific requirements and processing conditions of the workpiece, thereby improving the applicability of the chuck. By setting the anti-slip groove, the stability of the workpiece clamping is further improved when clamping the workpiece.

[0020] The present invention is further configured such that three scale lines are equidistantly arranged on the surface of the chuck body along the circumference, and the scale lines are matched with the adjacent movable jaws.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] A laser surface treatment machine tool chuck, such as Figure 1 - Figure 4As shown, it includes a chuck body 1, and the side wall of one side of the chuck body 1 has a wrench adjustment square hole 101. Three movable sliders 2 are movably installed at equal intervals along the circumference of the chuck body 1. The wrench adjustment square hole 101 is used to synchronously adjust the distance between the three movable sliders 2, and can clamp workpieces with regular surfaces, such as cylindrical or rectangular clamping and positioning. An adjustment component 3 is provided inside the movable slider 2, and a mounting block 4 is fixedly installed on the top of the adjustment component 3, and a cross-shaped groove 401 is opened on the top of the mounting block 4. A cross-shaped connecting block 5 is detachably installed on the top of the mounting block 4 through the cross-shaped groove 401, and a movable clamping claw 7 is fixedly installed on the top of the cross-shaped connecting block 5. By setting the adjustment component 3, the position of a single movable jaw 7 can be adjusted separately. When clamping a special-shaped workpiece, the jaw can form effective contact with the workpiece to improve the clamping effect of the workpiece. In addition, by setting the telescopic isolation belt 305, the interior of the movable groove 301 can be shielded during the movement of the threaded sleeve 303, thereby preventing waste chips from falling into the movable groove 301 during laser processing of the workpiece clamped by the chuck, thereby affecting the use of the adjusting screw rod 302.

[0033] See also Figure 1 and Figure 4 The adjusting component 3 includes: a movable groove 301, which is opened inside the movable slider 2, and an adjusting screw rod 302 is installed horizontally in the movable groove 301, and one end of the adjusting screw rod 302 extends to the outside of the movable slider 2, and a threaded sleeve 303 is threadedly installed on the surface of the adjusting screw rod 302, and the upper end of the threaded sleeve 303 extends to the outside of the movable slider 2, and a guide rod 304 is provided inside the upper end of the adjusting screw rod 302, and both ends of the guide rod 304 are fixedly connected to the inner wall of the movable groove 301, and the bottom of the mounting block 4 is fixedly connected to the middle position of the top of the threaded sleeve 303. When clamping a special-shaped workpiece, first rotate the knob at one end of the adjusting screw 302 to rotate the adjusting screw 302. At this time, the threaded sleeve 303 threadedly installed on the surface of the adjusting screw 302 moves horizontally under the guidance of the guide rod 304, thereby adjusting the position of the movable claw 7 above the single threaded sleeve 303. By adjusting the position of a single movable claw 7 separately, the claw can form effective contact with the workpiece when clamping the special-shaped workpiece, thereby improving the clamping effect of the workpiece.

[0034] See also Figure 1 and Figure 4 A retractable isolation belt 305 is fixedly mounted on both sides of the inner wall of the upper end of the movable groove 301, and one end of the retractable isolation belt 305 is fixedly connected to the outer wall of one side of the threaded sleeve 303. The internal connection between the retractable isolation belt 305 and the isolation belt is maintained taut by a spring, thereby preventing waste chips from falling into the movable groove 301 during laser processing of the workpiece clamped in the chuck, thereby affecting the use of the adjustment screw 302.

[0035] See also Figure 4 , both ends of the adjusting screw 302 are provided with bearings, and the inner ring of the bearing is fixedly connected to the surface of the adjusting screw 302, and the outer ring of the bearing is fixedly connected to the inner part of the moving slider 2. The bearing is provided to improve the stability of the rotation of the adjusting screw 302.

[0036] See also Figure 4 A knob is fixedly connected to one end of the adjusting screw 302, and a plurality of grooves are formed on the outer wall of the knob at equal intervals along the circumference. The grooves on the outer wall of the knob increase the friction between the hand and the knob when turning the knob on the end of the adjusting screw 302, thereby facilitating the rotation of the adjusting screw 302.

[0037] See also Figure 2 - Figure 3 Threaded holes 501 are formed around the cross-shaped connecting block 5. A hexagon socket nut 6 is threadedly mounted on one side of the mounting block 4, and one end of the hexagon socket nut 6 is threadedly mounted inside the adjacent threaded hole 501 through the cross-shaped groove 401. When it is necessary to adjust the corresponding clamping jaw according to the shape of the clamped workpiece, the hexagon socket nut 6 is screwed out of the threaded hole 501 by using a wrench, and the position of the clamping jaw on the movable clamping jaw 7 on the top of the cross-shaped connecting block 5 is adjusted. After that, one end of the hexagon socket nut 6 is screwed into the adjusted threaded hole 501. This facilitates adjustment of the clamping jaw according to the shape of the clamped workpiece, further improving the applicability of the chuck.

[0038] See also Figure 1 - Figure 4 The movable jaw 7 is surrounded by rectangular, curved, tapered, and hardened jaws, respectively. Anti-slip grooves are provided on the surfaces of the rectangular, curved, tapered, and hardened jaws. By providing different types of jaws around the movable jaw 7, the most suitable jaw type can be determined based on the workpiece's specific requirements and processing conditions during workpiece clamping, thereby expanding the chuck's applicability. The anti-slip grooves further enhance the stability of workpiece clamping.

[0039] See also Figure 1 - Figure 2 The surface of the chuck body 1 is provided with three scale lines equidistantly along the circumference, and the scale lines are matched with adjacent movable jaws 7. By setting the scale lines, the accuracy of the moving position of a single movable jaw 7 can be improved.

[0040] The working principle of the present invention is as follows: when clamping a special-shaped workpiece, the distance between the three movable sliders 2 is first adjusted synchronously by adjusting the square hole 101 with a wrench. After the adjustment is completed, due to the irregular surface of the special-shaped workpiece, some of the clamping jaws cannot form effective contact with the workpiece surface. At this time, the adjusting screw 302 is rotated by rotating the knob at one end of the adjusting screw 302. At this time, the threaded sleeve 303 threadedly installed on the surface of the adjusting screw 302 moves horizontally under the guidance of the guide rod 304, thereby adjusting the position of the movable jaw 7 above the single threaded sleeve 303. After adjusting each jaw individually, the clamping space can also be adapted to different types of workpieces. After the workpiece is clamped, the telescopic isolation belt 305 blocks the opening of the movable groove 301 to prevent waste chips from falling into the movable groove 301 during laser processing of the workpiece clamped by the chuck, affecting the use of the adjusting screw 302.

[0041] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
