Description

Technical Field

[0001] This utility model relates to the field of instrument processing technology, and in particular to an instrument smoothing steering platform. Background Technology

[0002] A mechanical smoothing turntable is a mechanical device used to achieve smooth rotation and positioning of equipment or workpieces. It is widely used in industrial production lines, medical equipment, stage machinery, and other fields. Its core function lies in ensuring a stable, precise, and vibration-free turning process through the coordinated work of mechanical, electrical, or hydraulic systems.

[0003] According to the patent application CN211073273U, "This utility model discloses a rotary table fixture for machining machinery, including a base, a turntable, and a fixture table. The turntable is provided on the upper surface of the base, and a rotary motor is embedded in the center of the upper surface of the base. The output shaft of the rotary motor is welded and fixed to the bottom center of the turntable. A second slider is welded to the bottom of the rotary shaft. In this utility model, the fixture table is rotatably connected to a concave fixed frame via a rotary shaft. A servo motor is provided, and the servo motor can drive the fixture table to rotate vertically via the rotary shaft, which facilitates the adjustment of the vertical angle of the workpiece fixed on the fixture table. The concave fixed frame is fixed on the turntable, and the rotary motor embedded in the base drives the turntable to rotate, so that the workpiece fixed on the fixture table can be adjusted horizontally. Therefore, this rotary table fixture for machining machinery can achieve horizontal and vertical angle adjustment, and can perform multi-directional and multi-angle machining on the workpiece fixed on the fixture table."

[0004] Regarding the above description, the applicant believes the following problems exist: The upper surface of the fixture table of the device is provided with a strip-shaped sliding groove, which is slidably connected to an inverted L-shaped fixed plate through the first slider. The pressure plate is driven by an electric push rod to press the workpiece. The four electric push rods push the two pressure plates to press the workpiece together, which causes unnecessary waste; when the first sliders on both sides are manually adjusted, due to the lack of reference positioning, it is difficult to ensure the symmetry of both sides, which may lead to poor workpiece centering and affect the machining accuracy. Moreover, after each workpiece change, the slider position needs to be readjusted, which is inefficient and inconsistent; at the same time, since the turntable only relies on the rotary motor for drive, it cannot lock the angle during machining, which leads to position drift and affects the machining accuracy. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a smooth turning table for machinery, which has the functions of locking the horizontal and vertical angles during processing and the function of automatic centering with synchronous clamping of the pressure plates on both sides, thereby improving the adaptability of the device and the processing accuracy, while reducing the number of electric push rods and reducing costs.

[0006] The objective of this utility model is achieved through the following technical solution: The instrument's smooth turning platform includes a base, a rotary motor, and a clamping assembly. The rotary motor is fixedly connected inside the base, and a worm gear is fixedly connected to the output end of the rotary motor. A retainer is fixedly connected to the end of the base away from the motor. A worm wheel is meshed with the external part of the worm gear. The rotary motor drives the worm gear to rotate, causing the worm wheel to rotate. A shaft is fixedly connected inside the worm wheel. A turntable is fixedly connected to the end of the shaft away from the worm wheel. A mounting bracket is fixedly connected to the top of the turntable. A servo motor is fixedly connected to the external part of the mounting bracket. A worm gear is fixedly connected to the output end of the servo motor. A worm wheel is meshed with the external part of the worm gear. The servo motor drives the worm gear to rotate, causing the worm wheel to rotate. A shaft is fixedly connected inside the worm wheel. A clamping platform is fixedly connected to the shaft, and the clamping assembly is mounted on the clamping platform.

[0007] In one alternative implementation, the turntable rotates when the worm gear rotates, and the turntable is locked when the worm gear stops.

[0008] In one optional embodiment, the clamping assembly includes a second servo motor, the output end of which is fixedly connected to a ball screw, which drives the ball screw to rotate. Ball nuts are rolledly connected to both ends of the ball screw. A slider is fixedly connected to the outside of the ball nuts. Bolts are threadedly connected to the inside of the slider. A fixing plate is fixedly connected to the outside of the slider away from the ball nuts. An electric push rod is fixedly connected to the top of the fixing plate. A pressure plate is fixedly connected to the output end of the electric push rod, which drives the pressure plate to rise and fall. Limit rods are fixedly connected to both ends of the pressure plate. A guide rail is fixedly connected inside the clamping table. A shaft connector is fixedly connected to the ball screw.

[0009] In one alternative implementation, when the ball screw rotates, the ball nuts at both ends of the ball screw move closer or further apart synchronously.

[0010] In one optional implementation, when the bolt is tightened, the slider is in a locked state and the servo motor 2 cannot be started; when the bolt is loosened, the slider is in an unlocked state and the servo motor 2 can drive the slider to move.

[0011] In one optional embodiment, the bottom of the slider has a groove and the inside has a through hole. The slider is slidably connected to the guide rail through the groove and slidably connected to the ball screw through the through hole.

[0012] In one optional embodiment, two through holes are provided at both ends of the fixed plate, and the limiting rod is slidably connected inside the fixed plate through the two through holes to limit the rotation of the pressure plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By using a worm gear structure with both horizontal and vertical rotation drives, the angle locking effect in the horizontal and vertical directions during machining is achieved, which alleviates the problem that relying solely on a rotary motor drive cannot lock the angle during machining, and improves the adaptability of the device and machining accuracy.

[0014] 2. The structure, which uses a servo motor to drive the ball screw to move the clamping plates at both ends synchronously, realizes the function of synchronous clamping and automatic centering of the two pressure plates, which alleviates the problem of poor workpiece centering caused by the difficulty in ensuring symmetry on both sides when manually adjusting the clamping plates, and improves the machining accuracy.

[0015] 3. An electric push rod is fixedly connected to the top of the fixed plate, and a pressure plate is fixedly connected to the output end of the electric push rod. Limit rods are fixedly connected to both ends of the pressure plate. This structure realizes the function of fixing one side of the pressure plate with a single push rod, which alleviates the problem of increased cost caused by fixing the pressure plate with multiple push rods and reduces costs.

[0022] Please refer to Figure 1-6The instrument's smooth turning platform includes a base 1, a rotary motor 201, and a clamping assembly. The rotary motor 201 is fixedly connected inside the base 1. A worm gear 202 is fixedly connected to the output end of the rotary motor 201. A retainer 203 is fixedly connected to the end of the base 1 away from the rotary motor 201. A worm wheel 204 is meshed with the outside of the worm gear 202. The rotary motor 201 drives the worm gear 202 to rotate, thereby rotating the worm wheel 204. A shaft 205 is fixedly connected inside the worm wheel 204. A turntable 206 is fixedly connected to the end of the shaft 205 away from the worm wheel 204. A mounting bracket 207 is fixedly connected to the top of the turntable 206. A servo motor 208 is fixedly connected to the outside of the mounting bracket 207. The output of the servo motor 208... A worm gear 209 is fixedly connected to the end of the device. A worm wheel 210 is externally meshed with the worm gear 209. A servo motor 208 drives the worm gear 209 to rotate, which in turn drives the worm wheel 210 to rotate. A shaft 211 is fixedly connected inside the worm wheel 210. A clamping table 212 is fixedly connected to the shaft 211. A clamping assembly is provided on the clamping table 212. When the device is in use, the instrument is installed on the clamping table 212. The rotary motor 201 is started to drive the worm gear 202 to rotate, which in turn drives the worm wheel 204 to rotate, causing the turntable 206 to rotate. The horizontal angle of the turntable 206 is adjusted. The servo motor 208 is started to drive the worm gear 209 to rotate, which in turn drives the worm wheel 210 to rotate, causing the clamping table 212 to rotate. The vertical angle of the clamping table 212 is adjusted, and finally, the operation begins.

[0023] In a preferred embodiment of this utility model, when the worm gear 202 rotates, the turntable 206 rotates; when the worm gear 202 stops, the turntable 206 is in a locked state. The arrangement of the worm gear 202 facilitates the rotation and locking of the turntable 206.

[0024] Please refer to Figures 5-6In a preferred embodiment of this utility model, the clamping assembly includes a second servo motor 301, the output end of which is fixedly connected to a ball screw 302. The second servo motor 301 drives the ball screw 302 to rotate. Ball nuts 303 are rolledly connected to both ends of the ball screw 302. A slider 304 is fixedly connected to the outside of the ball nuts 303. A bolt 305 is threaded inside the slider 304. A fixing plate 306 is fixedly connected to the outer end of the slider 304 away from the ball nuts 303. An electric push rod 307 is fixedly connected to the top of the fixing plate 306. The output end of the electric push rod 307... A pressure plate 308 is fixedly connected, and an electric push rod 307 is used to drive the lifting and lowering of the pressure plate 308. Limit rods 309 are fixedly connected to both ends of the pressure plate 308. A guide rail 310 is fixedly connected inside the clamping table 212, and a shaft connector 311 is fixedly connected to the ball screw 302. When the device is in use, the instrument is placed on the clamping table 212, and then the bolts 305 are ensured to be loosened. Then, the servo motor 301 is started to drive the ball screw 302 to rotate, causing the ball nuts 303 at both ends to move closer synchronously, so that the sliders 304 on both sides move the fixing plate 306 closer synchronously, fixing the instrument from the side. Then, the two... The electric push rod 307 on the end fixing plate 306 drives the pressure plate 308 to descend, pressing and fixing the instrument. When the ball screw 302 rotates, the ball nuts 303 at both ends of the ball screw 302 move closer or further away synchronously. The ball screw 302 facilitates the synchronous movement of the ball nuts 303 at both ends. When the bolt 305 is tightened, the slider 304 is in a locked state, and the servo motor 301 cannot be started. When the bolt 305 is loosened, the slider 304 is in an unlocked state, and the servo motor 301 can drive the slider 304 to move. The bolt 305 facilitates the movement of the slider 304. The slider 304 has a groove at its bottom and a through hole inside. The slider 304 is slidably connected to the guide rail 310 through the groove and to the ball screw 302 through the through hole. The groove and through hole facilitate the sliding of the slider 304 on the guide rail 310 and the ball screw 302. The fixed plate 306 has through holes at both ends. The limiting rod 309 is slidably connected to the inside of the fixed plate 306 through the through hole, which restricts the rotation of the pressure plate 308. The through hole facilitates the sliding of the limiting rod 309 inside the fixed plate 306, so that the pressure plate 308 can only move up and down.

[0025] When using the device, place the instrument on the fixture table 212, ensure the bolts 305 are loose, then start the servo motor 2 301 to drive the ball screw 302 to rotate, causing the ball nuts 303 at both ends to move closer synchronously, so that the sliders 304 on both sides move the fixing plates 306 closer synchronously, fixing the instrument from the side. Then start the electric push rods 307 on the fixing plates 306 at both ends to drive the pressure plate 308 to descend, pressing and fixing the instrument. Start the rotary motor 201 to drive the worm gear 202 to rotate, causing the worm wheel 204 to rotate, making the turntable 206 rotate. Adjust the horizontal angle of the turntable 206. Start the servo motor 208 to drive the worm gear 209 to rotate, causing the worm wheel 210 to rotate, making the fixture table 212 rotate. Adjust the vertical angle of the fixture table 212, and finally start the operation.
