DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] refer to Figures 1 to 6 The present invention provides an automatic CNC turning production line for bearing rings, comprising: a CNC machine tool 1, a feeding table 3 located on one side of the CNC machine tool 1, a material transfer device 2 for clamping and moving a workpiece, and a controller for controlling the CNC machine and various devices. A loading device 4 is installed on the top of the feeding table 3 for transferring the workpiece to be processed to the gripping position of the material transfer device 2;

[0030] The CNC machine tool 1 comprises a bed 5 with a side opening, a processing mechanism 7 mounted on the inner side of the bed 5, and a fixing mechanism 6 opposite to the processing mechanism 7 for clamping, rotating and moving the workpiece;

[0031] The material moving device 2 includes a support frame 201 connected to the side of the feeding table 3, and a movable slide rail 202 is installed on the upper end of the support frame 201. The movable slide rail 202 is connected to the movable plate 203 through a slider. The two ends of the bottom of the movable plate 203 are connected to a first rotating plate 204 and a second rotating plate 207. The first rotating plate 204 and the second rotating plate 207 are respectively rotatably connected to the outer surface of the first rotating shaft 205 and one end of the second rotating shaft 208. One end of the first rotating shaft 205 passes through the first rotating plate 204 and The driving end of the first motor 206 is connected, and the other ends of the first rotating shaft 205 and the second rotating shaft 208 are respectively connected to the two side surfaces of the material moving cylinder 209, and the telescopic end of the material moving cylinder 209 is connected to the top of the circular mounting plate 210, and the bottom of the mounting plate 210 is connected to the peripheral side surface of the clamping ring 212 through multiple connecting rods 211. Multiple clamping cylinders 213 are installed on the peripheral side surface of the clamping ring 212, and the telescopic end of the clamping cylinder 213 passes through the peripheral side surface of the clamping ring 212 and is connected to the clamping plate 214.

[0032] In the embodiment of the present invention, reference Figure 4 As shown, a clamping pad 215 made of rubber material is bonded to the side surface of the clamping ring 212 .

[0033] It should be noted that the control device uses an existing controller with a display screen, and the clamping cylinders 213 are distributed in an equidistant circle around the central axis of the clamping ring 212 on the circumferential surface of the clamping ring 212.

[0034] By extending and retracting the clamping cylinder 213, the clamping plate 214 can be moved, so that different clamping plates 214 can contact different positions of the peripheral side of the workpiece. Multiple clamping plates 214 cooperate with each other to limit and fix the workpiece between the clamping plates 214, thereby achieving clamping of the workpiece. By extending and retracting the material moving cylinder 209, the workpiece fixed between the clamping plates 214 can be moved up and down, and by moving the slide rail 202, the workpiece can be moved between the feeding table 3 and the bed 5. Through the above structure, automatic loading and unloading of workpieces can be realized without the need for human operation, thereby preventing the loading and unloading efficiency from being reduced due to human fatigue during operation.

[0035] And through the rotation of the first motor 206, the clamped workpiece can be rotated, and the workpiece can be rotated from the side facing down to the side opposite to the fixing mechanism 6, and through the movement of the fixing mechanism 6, the side of the workpiece is brought into contact with the side of the fixing mechanism 6, and the fixing mechanism 6 is used to realize automatic clamping of the workpiece, thereby preventing the existing manual clamping. During the operation, due to fatigue caused by workers' long-term clamping operations, problems such as loose clamping and inaccurate positioning are caused, which easily lead to rework and scrapping of the bearing ring.

[0036] In the embodiment of the present invention, reference Figure 5、 Figure 6 As shown, the fixing mechanism 6 includes a fixing column 301, and a plurality of fixing grooves 302 are provided on the side of the fixing column 301. A fixed slide rail 303 is installed inside the fixing groove 302. The fixed slide rail 303 is connected to the fixing plate 304 through a slider. The other side of the fixing column 301 is connected to the driving end of the steering motor 305. The steering motor 305 is connected to the side of the connecting seat 306. The bottom of the connecting seat 306 is connected to the top of the base plate 307. The bottom of the base plate 307 is slidably connected to the slider and the transverse slide rail 312 through the connecting plate. The transverse slide rail 312 is installed on the top of the support seat 308. The bottom of the support seat 308 is slidably connected to the longitudinal slide rail 309 through the slider. The longitudinal slide rail 309 is installed at the bottom end inside the bed 5.

[0037] In the embodiment of the present invention, reference Figure 5 、 Figure 6 As shown, the processing mechanism 7 includes a moving cylinder 401, the side of the moving cylinder 401 is connected to the inner side of the bed 5, the telescopic end of the moving cylinder 401 is connected to the side of the guide plate 402, and a rotating motor 405 is installed on the side of the guide plate 402. The driving end of the rotating motor 405 is connected to the side of the tool mounting cylinder 404, and the rotating motor 405 is installed in a motor box 403 connected to the side of the guide plate 402.

[0038] It should be noted that the tool mounting cylinder 404 uses an existing tool fixing device that is movably connected to the processing tool and can be used to install different types of processing tools. The clamping slides are equidistantly distributed around the central axis of the fixed column 301. The multiple clamping slides are controlled by a single control device to achieve synchronous movement of the multiple clamping slides.

[0039] By driving the longitudinal slide rail 309, the support seat 308 can be moved forward and backward inside the bed 5, and by driving the transverse slide rail 312, the bottom plate 307 can be moved left and right on the support seat 308, and then by the cooperation of the two slide rails, the bottom plate 307 and the components thereon can be moved in a plane inside the bed 5, and the steering motor 305 can be used to rotate the fixed column 301, thereby rotating the fixed plate 304 on one side of the fixed column 301, and the fixed plate 304 can be moved by the fixed slide rail 303.

[0040] When the workpiece to be processed contacts the side of the fixed column 301, the fixed slide rail 303 can be driven to make multiple fixed plates 304 contact different positions of the peripheral side of the workpiece, thereby realizing the clamping of the workpiece by multiple fixed plates 304, so that the workpiece is fixed between the fixed plates 304. Through the above structure, automatic clamping of the workpiece is achieved without manual operation, thereby improving the efficiency and accuracy of workpiece clamping.

[0041] In the embodiment of the present invention, reference Figure 5 、 Figure 6 As shown, the two ends of the base plate 307 are respectively connected to the first guide plate 313 and the second guide plate 314, and the first guide plate 313 and the second guide plate 314 are slidingly connected to the first guide groove 310 and the second guide groove 311, and the first guide groove 310 and the second guide groove 311 are respectively arranged at the two ends of the top of the support seat 308.

[0042] It should be noted that a distance is left between the first guide plate 313, the second guide plate 314 and the edge of the base plate 307 to prevent debris from entering the first guide groove 310 and the second guide groove 311 during processing. By setting the first guide plate 313 and the second guide plate 314, the stability of the base plate 307 when moving left and right can be improved through the limiting guidance of the first guide groove 310 and the second guide groove 311.

[0043] In the embodiment of the present invention, reference Figure 3 As shown, the loading device 4 includes a loading plate 101, and a plurality of loading troughs 102 are provided on the top of the loading plate 101. The bottom of the loading plate 101 is connected to the driving end of the loading motor. The loading motor is installed in the motor trough, and the motor trough is opened on the top of the feeding table 3.

[0044] It should be noted that: by setting up a rotating and movable loading plate 101, when loading, the raw materials to be processed can be rotated to the bottom of the movable slide rail 202 through the rotating part, which is convenient for the material moving device 2 to clamp the raw materials, and by setting up a loading trough 102, the loading trough 102 can be limited to prevent the raw materials from falling from the loading plate 101 during the rotation process.

[0045] In the embodiment of the present invention, reference Figure 3 As shown, a blanking plate 104 with a blanking trough 105 is provided on the feeding table 3 on one side of the loading device 4. The bottom of the blanking plate 104 is connected to the blanking slide rail 103 through a slider, and the bottom of the blanking slide rail 103 is installed on the top of the feeding table 3.

[0046] It should be noted that by providing the blanking plate 104 , the processed bearings can be automatically moved from one end of the feeding table 3 to the other end of the feeding table 3 by moving the blanking slide rail 103 , thereby realizing automatic blanking of the bearings.

[0047] The working principle of the bearing ring automatic CNC turning production line provided by the present invention is as follows:

[0048] By extending and retracting the clamping cylinder 213, the clamping plate 214 can be moved, so that different clamping plates 214 can contact different positions of the peripheral side of the workpiece. Multiple clamping plates 214 cooperate with each other to limit and fix the workpiece between the clamping plates 214, thereby achieving clamping of the workpiece. By extending and retracting the material moving cylinder 209, the workpiece fixed between the clamping plates 214 can be moved up and down, and by moving the slide rail 202, the workpiece can be moved between the feeding table 3 and the bed 5. Through the above structure, automatic loading and unloading of workpieces can be realized without the need for human operation, thereby preventing the loading and unloading efficiency from being reduced due to human fatigue during operation.

[0049] And through the rotation of the first motor 206, the clamped workpiece can be rotated, and the workpiece can be rotated from the side facing down to the side facing the fixing mechanism 6, and through the movement of the fixing mechanism 6, the side of the workpiece can be brought into contact with the side of the fixing mechanism 6, and through the drive of the fixed slide rail 303, the multiple fixing plates 304 can be respectively brought into contact with different positions of the peripheral side of the workpiece, thereby realizing the clamping of the workpiece by the multiple fixing plates 304, so that the workpiece is fixed between the fixing plates 304. Through the above structure, automatic clamping of the workpiece is realized without manual operation, thereby improving the efficiency and accuracy of workpiece clamping.
