Technical Field

[0001] The invention relates to the technical field of concentricity detection, in particular to a direct-connection type spindle concentricity laser detection device. Background Art

[0002] A direct-coupled spindle is one that is directly connected to a motor, so that the motor's output power can be fully expressed. It has high mechanical efficiency and is widely used in industrial equipment. The production quality of a direct-coupled spindle has a great impact on its normal operation. The higher the concentricity of the direct-coupled spindle, the smaller the runout and the higher the machining accuracy. On the contrary, the lower the concentricity of the direct-coupled spindle, the larger the runout and the lower the machining accuracy. Therefore, a concentricity test is required after the direct-coupled spindle is produced to ensure the production quality of the direct-coupled spindle.

[0003] In the actual inspection process of the existing direct-coupled spindle, in order to ensure the accuracy of the inspection, it is necessary to perform multiple inspections on different positions of the direct-coupled spindle.

DETAILED DESCRIPTION

[0026] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 7 The present invention provides a technical solution: a direct-connected spindle concentricity laser detection device, comprising a mounting frame 1, a cylinder 2 and a movable table 3, the mounting frame 1 is symmetrically fixed with the cylinder 2, the output end of the cylinder 2 is fixed with the movable table 3, and a rotating mechanism 4 is installed in the movable table 3.

[0028] A bottom pad 101 is fixed symmetrically on the lower end surface of the mounting frame 1, and a control panel 102 is also fixed on the mounting frame 1; an ear plate 301 is also fixed symmetrically on the movable platform 3, and the ear plate 301 is slidably connected to the slide bar 302, and the slide bar 302 is fixed on the mounting frame 1; the rotating shaft 401 forms a counterclockwise one-way rotation mechanism with the movable platform 3 through a one-way bearing 402, and the angle of each rotation of the rotating shaft 401 is 1°-10°; a clamping mechanism 5 is also fixed on the rotating shaft 401, and the clamping mechanism 5 includes a fixed plate 501, a guide rod 502, a second spring 503, a circular plate 504, a top rod 505, a top plate 506, a connecting rod 507 and The limiting rod 508 and the fixing plate 501 are fixed on the rotating shaft 401, and four groups of guide rods 502 are fixed at equal angles on the outside of the rotating shaft 401, and one end of the second spring 503 is fixed on the fixing plate 501, and the other end of the second spring 503 is fixed on the circular plate 504; one end of the top rod 505 is fixed on the circular plate 504, and the other end of the top rod 505 is fixed on the top plate 506; one end of the connecting rod 507 is rotatably connected to the circular plate 504, and the other end of the connecting rod 507 is rotatably connected to the limiting rod 508; the limiting rod 508 and the guide rod 502 are slidably connected, and the limiting rod 508 and the guide rod 502 are distributed one-to-one;

[0029] When using the direct-connected spindle concentricity laser detection device, Figure 1-Figure 7As shown, the direct-connected spindle workpiece to be inspected is placed between the left and right top plates 506, and then the cylinder 2 is controlled to start. The cylinder 2 is extended to drive the movable table 3, the rotating mechanism 4 and the clamping mechanism 5 to move. With the sliding guide effect between the ear plate 301 and the slide bar 302, the stability of the movement of the movable table 3, the rotating mechanism 4 and the clamping mechanism 5 can be ensured, so that the distance between the left and right top plates 506 can be adjusted. When the left and right top plates 506 are in contact with the end surface of the workpiece, the cylinder 2 continues to extend, so that the top plates 506 is forced to move relative to the fixed plate 501, and synchronously drives the circular plate 504 to move. When the circular plate 504 moves, the transmission effect of the connecting rod 507 can make the limit rod 508 move under force, and the sliding guide effect between the limit rod 508 and the guide rod 502 can ensure the stability of the movement of the limit rod 508, until the limit rod 508 contacts the direct-connected spindle workpiece to achieve clamping and fixing, thereby ensuring the stability of the workpiece. At this time, the center axis of the workpiece is flush with the center axis of the laser rangefinder 604.

[0030] The rotating mechanism 4 includes a rotating shaft 401, a one-way bearing 402, a friction wheel 403, a friction plate 404, a first spring 405, a fixing rod 406 and a dial plate 407. The rotating shaft 401 is connected to the movable platform 3 through the one-way bearing 402. The rotating shaft 401 is also fixed with a friction wheel 403 with a rough surface structure. The friction wheel 403 and the friction plate 404 with a rough surface structure are connected to each other. The friction plate 404 and the movable platform 3 are slidably connected. One end of the first spring 405 is also fixed to the friction plate 404, and the other end of the first spring 405 is fixed to the movable platform 3. A fixed rod 406 is also fixed on the friction plate 404. The fixed rod 406 is slidably connected to the movable table 3, and the fixed rod 406 is slidably connected to the dial plate 407. The end surface of the dial plate 407 is an inclined structure. The dial plate 407 is connected to the detection mechanism 6. The dial plate 407 is driven to move by the detection mechanism 6. The sliding action between the dial plate 407 and the fixed rod 406 causes the fixed rod 406 to move upward, thereby driving the friction plate 404 to move upward. The contact friction between the friction plate 404 and the friction wheel 403 causes the rotating shaft 401 to rotate.

[0031] The detection mechanism 6 includes a motor 601, a threaded rod 602, a movable frame 603, a laser rangefinder 604 and a crossbar 605. The motor 601 is fixed to the right end face of the mounting frame 1, and the output end of the motor 601 is fixed with a threaded rod 602, and the threaded rod 602 is connected to the mounting frame 1 by a bearing, and the threaded rod 602 is connected to the movable frame 603 by a thread, and the laser rangefinder 604 is fixed to the movable frame 603, and the central axis of the laser rangefinder 604 is on the same horizontal plane as the central axis of the movable platform 3, and the distance between the laser rangefinder 604 and the end of the limit rod 508 is equal to half the length of the dial plate 407; the movable frame 603 and the crossbar 605 are slidably connected, and the crossbar 605 is fixed to the mounting frame 1, and the dial plate 407 is fixed to the movable frame 603;

[0032] After the workpiece is fixed, Figure 1-Figure 7As shown, by controlling the motor 601 to start, the threaded rod 602 is driven to rotate, and the threaded connection between the threaded rod 602 and the movable frame 603 is coordinated, so that the movable frame 603 and the laser rangefinder 604 are forced to move, and the sliding guide between the movable frame 603 and the cross bar 605 can ensure the stability of the movement of the movable frame 603 and the laser rangefinder 604. Through the horizontal movement of the laser rangefinder 604, the one-time detection of the direct-connected spindle workpiece can be achieved (the concentricity of the direct-connected spindle can be determined by detecting the distance from the laser rangefinder 604 to the surface of the direct-connected spindle), and the movable frame 603 and the laser rangefinder 604 are connected. During the movement, the dial plate 407 is synchronously driven to move. When the laser rangefinder 604 moves to be flush with the end of the limit rod 508, the inclined surface of the dial plate 407 is just aligned with the fixed rod 406. At this time, the laser rangefinder 604 and the dial plate 407 continue to move, and the sliding action between the inclined surface of the dial plate 407 and the fixed rod 406 causes the fixed rod 406 to move upward under force, thereby driving the friction plate 404 to move upward synchronously under force. The sliding guide action between the friction plate 404 and the movable platform 3 can ensure the stability of the movement of the friction plate 404, and when the friction plate 404 moves upward, the friction transmission action between the friction plate 404 and the friction wheel 403 can make The rotating shaft 401 rotates until the fixed rod 406 contacts the plane of the dial plate 407. At this time, the rotating shaft 401 completes its rotation. When the rotating shaft 401 rotates, it synchronously drives the clamping mechanism 5 and the direct-connected spindle workpiece to rotate, thereby realizing the angle adjustment function of the direct-connected spindle workpiece (wherein the rotation angle of the rotating shaft 401 is proportional to the moving distance of the friction plate 404, that is, the rotation angle of the rotating shaft 401 can be controlled by controlling the inclined height of the dial plate 407, so as to better meet the actual use requirements). After the rotation is completed, the threaded rod 602 is driven to reverse by controlling the motor 601, so that the movable frame 603 and the laser rangefinder 604 move in the opposite direction. The laser rangefinder 604 can be used to perform secondary detection of the direct-connected spindle workpiece, and when the fixed rod 406 is separated from the paddle plate 407, the friction plate 404 and the fixed rod 406 can be reset by the elastic action of the first spring 405. Due to the action of the one-way bearing 402, it can be ensured that the friction plate 404 will not drive the rotating shaft 401 to rotate in the opposite direction when it is reset. According to the above principle, the sliding action of the fixed rod 406 and the paddle plate 407 can realize automatic adjustment of the workpiece angle, and the reciprocating motion of the laser rangefinder 604 can realize comprehensive detection of the workpiece. This is the working principle of the direct-connected spindle concentricity laser detection device.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
