Description

Technical Field

[0001] This utility model belongs to the field of laser cladding technology, and in particular relates to a laser cladding rotary table. Background Technology

[0002] During laser cladding, quenching and other operations, the workpiece needs to be mounted on a "rotary worktable" and rotate synchronously with the spindle of the rotary worktable.

[0003] Because the materials, diameters, and lengths of the workpieces vary, the rotational speed of the rotary table and the position of the tailstock during laser cladding operations must be adjusted according to the process requirements. Currently used rotary tables rely on frequency converters for speed regulation, but the rotational speed cannot be quantified or visualized, relying entirely on the operator's visual judgment to set the speed; the geared motor directly drives the spindle to rotate, making it laborious and time-consuming to load and rotate the workpiece; the tailstock is mounted on the base and secured with bolts, requiring a crane to move and adjust its position, further extending the workpiece loading time.

[0004] In the prior art, patent publication number CN222512974U discloses a laser cladding device with a constant force pneumatic tailstock. It uses a pneumatic device to drive the movement of the ejector pin, which solves the problem that the force exerted by the ejector pin on the shaft parts is too large, causing damage to the ejector pin and shaft parts. However, the stroke of the ejector pin is limited, which cannot meet the processing needs of different workshops. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a laser cladding rotary table that solves the problems of laborious operation and inconvenient tailstock adjustment. The tailstock can be moved conveniently and quickly, and the workpiece clamping is time-saving and labor-saving, thus improving work efficiency.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A laser cladding rotary table includes a base, a spindle box assembly, a tailstock assembly, and an electrical control box. The spindle box assembly is fixedly connected to the base, a traveling frame is provided between the tailstock assembly and the base, and the electrical control box is installed inside the spindle box assembly.

[0008] The tailstock assembly includes a tailstock, an ejector pin assembly, a traveling frame, guide wheels, and a locking screw. The ejector pin assembly is fixed on the tailstock, the traveling frame is connected to the guide wheels, and the locking screw is threadedly connected to the tailstock and the traveling frame.

[0009] The base is a welded structural component, which includes a slide rail, a mounting platform, and a flat base. The slide rail and the mounting platform are fixed on the flat base. The top of the slide rail is the mounting surface. The mounting platform is provided with a bolt hole. The mounting platform is assembled and connected to the spindle box.

[0010] The slide rail is composed of two parallel H-beams, channel steels, or I-beams.

[0011] The tailstock assembly also includes a thrust bearing I, a thrust bearing II, a nut, a threaded hole I, a mounting surface II, a countersunk hole I, and a countersunk hole II. The bottom of both sides of the tailstock is the mounting surface II, which can fit against the base. The tailstock is provided with a threaded hole I, and a locking screw is threadedly connected to the threaded hole I. The upper and lower surfaces of the traveling frame are respectively provided with countersunk hole I and countersunk hole II. The threaded hole I, countersunk hole I, and countersunk hole II are coaxially arranged. The locking screw passes through countersunk hole I and countersunk hole II and is connected to the nut. The thrust bearing I is pressed into countersunk hole I by the locking screw, and the thrust bearing II is pressed into countersunk hole II by the nut. The guide wheel can move on the slide of the base.

[0012] The locking screw is an integral structure, including an upper screw, a lower screw, and a shoulder. The upper screw and the lower screw have a shoulder. The diameter of the upper screw is larger than that of the lower screw. Both the upper screw and the lower screw are threaded on the outside. The top of the upper screw is a square head or a hexagonal head.

[0013] The spindle box assembly includes a housing, a pinion, a clutch, a geared motor, a chuck, a bearing housing, a spindle, and a large gear. The housing is a welded structure and is fixedly connected to the base. The pinion is fixedly connected to the clutch, and the clutch is keyed to the output shaft of the geared motor.

[0035] See Figures 1-13 A laser cladding rotary table includes a base 1, a spindle 27 box assembly 2, a tailstock 41 assembly 4, and an electrical control box 5. The base 1 is placed on the ground or foundation, the spindle 27 box assembly 2 is fixedly connected to the base 1, and a traveling frame 43 is provided between the tailstock 41 assembly 4 and the base 1. The electrical control box 5 is installed inside the spindle 27 box assembly 2, which can save space and facilitate operation. The overall structure is compact and suitable for industrial site environments.

[0036] See Figure 2 The base 1 is a welded structural component, comprising a slide rail 13, a mounting platform 14, and a flat base. The slide rail 13 and mounting platform 14 are fixed to the flat base. The top of the slide rail 13 is a mounting surface. The mounting platform 14 has bolt holes 11 and is connected to the spindle 27 housing assembly 2. The tailstock 41 assembly 4 is movable on the slide rail 13. The pin assembly 42 of the tailstock 41 assembly 4 is coaxial with the chuck 25 of the spindle 27 housing assembly 2. The slide rail 13 is composed of two parallel H-beams, channel steels, or I-beams, and can be welded and fixed to the base 1.

[0037] See Figures 4-12 The tailstock 41 assembly 4 includes a tailstock 41, a ejector assembly 42, a traveling frame 43, a guide wheel 44, and a locking screw 45. The ejector assembly 42 is fixed on the tailstock 41, the traveling frame 43 is connected to the guide wheel 44, the locking screw 45 is threadedly connected to the tailstock 41, and the locking screw 45 is connected to the traveling frame 43.

[0038] The tailstock 41 assembly 4 includes a thrust bearing 46, a thrust bearing 47, a nut 48, a threaded hole I, a mounting surface II, a countersunk hole III, and a countersunk hole IV. The bottom of both sides of the tailstock 41 is the mounting surface II, which can fit with the mounting surface I 12 of the base 1. The tailstock 41 is provided with a threaded hole I, and the locking screw 45 is threadedly connected to the threaded hole I. The upper and lower surfaces of the traveling frame 43 are respectively provided with countersunk hole III and countersunk hole IV. The threaded hole I, countersunk hole I III, and countersunk hole II IV are coaxially arranged. The locking screw 45 passes through countersunk hole I III and countersunk hole II IV and is connected to the nut 48. Thrust bearing I 46 is pressed into countersunk hole I III by the shoulder 454 of the locking screw 45, and thrust bearing II 47 is pressed into countersunk hole II IV by the nut 48. The guide wheel 44 is fixed to the traveling frame 43 by the nut in through hole I V, and the guide wheel 44 can move on the slide rail 13 of the base 1. The locking screw 45 is an integral structure, including an upper screw 452, a lower screw 453, and a shoulder 454. The shoulder 454 between the upper screw 452 and the lower screw 453 can press the thrust bearing I 46 into countersunk hole I III. The diameter of the upper screw 452 is larger than that of the lower screw 453. Both the upper screw 452 and the lower screw 453 are threaded on the outside. The top of the upper screw 452 is a square head 451 or a hexagonal head. Rotating the locking screw 45 causes it to rise or fall, and the traveling frame 43 rises or falls along with it. The installation of thrust bearing 46 and thrust bearing 47 reduces the torque required to rotate the locking screw 45, saving effort. When the traveling frame 43 falls, the guide wheel 44 engages with the slide rail 13, enabling the tailstock assembly 4 to move in a push-pull motion. When the traveling frame 43 rises, the tailstock assembly 4 is secured to the mounting surface 12.

[0039] See Figure 3 The spindle 27 housing assembly 2 includes a housing 21, a pinion 22, a clutch 23, a geared motor 24, a chuck 25, a bearing housing 26, a spindle 27, and a large gear 28. The housing 21 is a welded structure and is bolted to the base 1 via bolt holes 11 on the mounting platform 14. The pinion 22 is bolted to the clutch 23, and the clutch 23 is keyed to the output shaft of the geared motor 24, which is fixed inside the housing 21. The chuck 25 is fixedly connected to one end of the spindle 27, and the large gear 28 is fixedly connected to the other end of the spindle 27, meshing with the pinion 22. The spindle 27 is connected to the bearing housing 26, which is fixedly connected to the housing 21. The spindle 27 housing assembly 2 also includes a cover 3, which is a welded structure and bolted to the top of the spindle 27 housing assembly 2.

[0040] See Figure 13 The electrical control box 5 is connected to a digital display tachometer 51 and a potentiometer 52. The speed of the spindle 27 is set by adjusting the value of the potentiometer 52, and the speed value of the spindle 27 can be displayed on the screen of the digital display tachometer 51 in real time.

[0041] See Figures 1-13 Laser cladding rotary table operation process:

[0042] 1. One end of the workpiece is clamped by the chuck 25, and the other end abuts against the ejector pin assembly 42. When the clutch 23 is not powered, the chuck 25 can be easily rotated manually.

[0043] 2. When the locking screw 45 is rotated to rise, the tailstock 41 descends and sits on the mounting surface 12 of the base 1. The traveling frame 43 rises and clamps with the back of the mounting surface 12 of the base 1. The guide wheel 44 disengages from the slide rail 13, thus fixing the tailstock 41.

[0044] 3. When the locking screw 45 is rotated to lower it, the traveling frame 43 follows and lowers, the guide wheel 44 falls onto the slide rail 13, and the tailstock 41 rises and disengages from the mounting surface 12 of the base 1, thus realizing the easy movement of the tailstock 41.

[0045] This utility model features a transmission system equipped with a clutch 23. The tailstock 41 adopts a guide wheel 44 structure, and the tailstock 41 can be fixed or moved simply by adjusting the locking screw 45, eliminating the need for a crane to adjust the position of the tailstock 41 and accommodating various workpiece clamping requirements. This utility model features precise and visible spindle speed setting for the spindle 27, convenient and rapid movement of the tailstock 41, and time-saving and labor-saving workpiece clamping.
