Detailed Description

Referring to fig. 1 and 2, the automatic transfer feeding device for the piston ring cutting equipment provided by the invention comprises a clamping and conveying assembly 2, a detection assembly 3, a lifting assembly 4 and a clamping and supporting assembly 5 which are arranged on a base plate 1 in a transverse mode, wherein the detection assembly 3 and the lifting assembly 4 are combined to form two gantries respectively to span on the clamping and conveying assembly 2, and the clamping and supporting assembly 5 is arranged on the lifting assembly 4 and is positioned above the clamping and conveying assembly 2.

Referring to fig. 3, the pinch assembly 2 comprises a linear guide and transmission mechanism 201 installed on the bottom plate 1, a traverse servo motor 205 on the linear guide and transmission mechanism 201, a slide block driven by the traverse servo motor 205, a translation gas claw 204 arranged on the slide block, a discharge platform 202 spanned on the translation gas claw 204, a clamping jaw mounting seat 203 installed on a translation arm of the translation gas claw 204, and a V-shaped clamping jaw 206 installed on the clamping jaw mounting seat 203.

The translating gas claw 204 and the discharge platform 202 can move back and forth with the slide, and the V-shaped clamping claw 206 can open and close with the opening and closing of the translating gas claw 204, thereby clamping the workpiece or releasing the workpiece.

Referring to fig. 4, the detecting assembly 3 includes a detecting frame 306 mounted on the bottom plate 1, a traverse linear guide 307 and a trapezoidal screw 302 transversely mounted on the detecting frame 306, a sensor mounting seat 303 fixed on a pulley of the traverse linear guide 307 and connected with a nut of the trapezoidal screw 302, a laser detecting sensor 301 mounted on the sensor mounting seat 303, a fine adjusting knob 304 arranged on the detecting frame 306 and connected with the trapezoidal screw 302, and a digital display recorder 305; the device also comprises a detection lifting cylinder 308 which is arranged on a lifting mechanism frame 401 of the lifting component 4 and is positioned above the pinch component 2, and a detection pressing block 309 which is arranged on a piston rod of the detection lifting cylinder 308 (see fig. 5).

The trapezoidal lead screw 302 rotates, the nut drives the sensor mounting seat 303 to move, and the laser sensor 301 is indirectly driven to move, so that the laser irradiation position is changed. The fine adjustment knob 304 is a mechanism that drives the trapezoidal lead screw 302 to rotate.

The detection component 3 is mainly used for detecting the thickness of the workpiece machined in the previous process by using a laser thickness measuring sensor to see whether the workpiece meets the requirement of supplied materials. The design is that the knob is adjustable, mainly in order to adapt to the product of different diameter specifications. Then, the position indicated by the laser thickness measuring sensor of different diameter specifications is recorded by the digital display recorder 305. When a new product is produced, after the position of an irradiation point of the laser thickness measuring sensor is adjusted, the position data of the digital display recorder 305 is recorded, and when the product is produced next time, the corresponding position data of the digital display recorder is directly adjusted, so that the knob is not required to be adjusted through repeated observation and calibration.

The detection lifting cylinder 308 and the detection pressing block 309 are mounted on the lifting frame 401 of the lifting assembly 4, so as to avoid detecting the movement of the lifting cylinder and causing vibration, thereby affecting the precision and stability of the laser sensor 301 in the detection assembly 3.

Referring to fig. 5, the lifting assembly 4 includes a lifting mechanism frame 401 mounted on the base plate 1, a linear guide rail 404 and a lifting servo motor 405 mounted on the lifting mechanism frame 401, a lifting screw 402 connected to the lifting servo motor 405 through a coupling, and a lifting frame 403 connected to a screw nut and mounted on a slide block of the linear guide rail 404.

The lifting servo motor 405 drives the lifting screw rod 407 to drive the lifting frame 403 to lift up and down for accurate positioning.

Referring to fig. 6, the clamp holder assembly 5 is mounted on a beam 4031 of a lifting frame 403 in the lifting assembly 4 (see fig. 5), and consists of a clamp ring arm 501, a clamp ring translation air claw 502, a clamping jaw 503, a support arm 504, a pressure arm 505 and a pressure arm air cylinder 506; the clamp ring arms 501 are arranged at two ends of the clamp ring translation gas claw 502, a press arm cylinder 506 and a clamp claw 503 are arranged at the end part of each clamp ring arm 501, a movable press arm 505 and a fixed support arm 504 are respectively arranged at the upper part and the lower part of the middle of the clamp claw 503, and the press arm 505 is connected with the press arm cylinder 506.

When the clamp ring translation gas claw 502 extends, the two clamp ring arms 501 are driven to open, so that the clamping jaws 503 clamp the workpiece, when clamping is performed, the workpiece is just supported by the support arms 504 at the lower parts of the clamping jaws 503, then the pressing arm air cylinder 506 drives the pressing arms 505 to press the workpiece, so that the workpiece is firmly bound, when the workpiece rises to a corresponding position, the workpiece main shaft is waited to take the material, after the workpiece main shaft firmly grips the material, the pressing arm air cylinder 506 drives the pressing arms 505 to loosen the workpiece, and then the clamp ring translation gas claw 502 is loosened.

Workflow of the invention

Manually or by equipment, the workpiece is placed on the placing platform 202 of the clamping and conveying assembly 2, and after the workpiece is placed fully, the PLC program controls the parts to execute the following actions:

the translational gas claw 204 moves firstly, and draws together to drive the V-shaped clamping jaw 206 to clamp the workpiece, wherein the translational servo motor 205 of the linear guide and transmission mechanism 201 drives the translational gas claw 204 and the discharge platform 202 to move, and stops under the detection assembly 3, and the translational gas claw 204 unloads but does not loosen.

The piston rod of the detection lifting cylinder 308 descends to drive the detection pressing block 309 to descend so as to press the workpiece, so that the workpiece is flattened, meanwhile, the translation gas claw 204 of the clamping and conveying assembly 2 clamps, and the laser detection sensor 301 of the detection assembly 3 detects and judges the workpiece; if the workpiece is qualified, the next procedure can be carried out, otherwise, the clamping and conveying assembly conveys the workpiece to the original position and takes the workpiece away manually or by equipment.

When the workpiece is qualified, the next process is carried out, the piston rod of the detection lifting cylinder 308 retracts to drive the detection pressing block 309 to retract, the translation servo motor 205 of the linear guide and transmission mechanism 201 drives the translation gas claw 204 and the discharging platform 202 to move continuously, the workpiece reaches the lower part of the lifting assembly 4 to stop, and the secondary carrying process is carried out.

Firstly, a lifting servo motor 405 in a lifting assembly 4 drives a lifting screw rod 402, a screw rod nut drives a lifting frame 403 to descend, so as to drive a clamping and supporting assembly 5 to descend to a low position, then a clamping ring translation gas claw 502 of the clamping and supporting assembly 5 is closed, a clamping ring arm 501 is driven to be closed, so as to drive a clamping jaw 503 to clamp a workpiece, and then a pressing arm cylinder 506 drives a pressing arm 505 to press the workpiece, so that the workpiece is firmly bound. Next, the elevation servomotor 405 drives the elevation screw 402 to rise to the high position, and waits for the workpiece spindle to pass to take the workpiece. After the workpiece spindle descends to take the workpiece, the transfer is completed, the clamping and supporting component 5 restores to the initial state, the lifting component 4 is still in the initial state, and the next cycle is waited.
