The cam divider 201 is located below the disc 102, and the output rod end of the cam divider 201 is flange-connected to the lower end face of the disc 102.

[0053] As can be seen from the above, by driving the cam divider 201 to drive the disc 102 to rotate, the upper pin springs 9 installed on the workpiece fixture sequentially enter the feeding station 103, the strong pressing station 104, the resistance detection station 105 and the blanking station with corresponding resistance values, and the feeding, strong pressing treatment, resistance measurement and sorting processes are carried out in sequence.

[0056] As can be seen from the above, the vibrating bowl 301 is driven to orderly arrange and convey the upper pin springs to be processed to the guiding groove 303. Then, by driving the feeding cylinder 304 to act, the pushing plate 305 is driven to push the upper pin spring 9 along the track of the guiding groove 303 to the workpiece fixture at the feeding station 103, so that the upper pin spring 9 is fixed on the workpiece fixture, completing the feeding of the upper pin spring 9. After that, by driving the lifting cylinder 306 to act, the feeding cylinder 304 is driven to rise. Then, the push rod of the feeding cylinder 304 is controlled to reset, and then the push rod of the lifting cylinder 306 is controlled to reset, so that the feeding cylinder 304 returns to the original working point. During the process after the feeding cylinder 304 is lifted, the vibrating bowl 301 is simultaneously driven to convey a new upper pin spring 9 into the guiding groove 303, so that there is no position interference between the feeding cylinder 304 and the new upper pin spring 9, and the working efficiency is effectively improved.

[0058] The second fixing plate 401 is fixedly installed above the workbench 101 by bolts. The stepping motor 402 is fixedly installed at the upper end of the second fixing plate 401 on the side away from the disk 102 by bolts. A through hole is provided on the second fixing plate 401, and the output shaft of the stepping motor 402 passes through the second fixing plate 401 through the through hole and is key-connected to the center of the rocking plate 403. The rocking plate 403 is located on the side of the second fixing plate 401 away from the stepping motor 402. The eccentric position of the rocking plate 403 is hinged to one end of the straight connecting rod 404 through a rotating shaft, and the straight connecting rod 404 is located on the side of the rocking plate 403 away from the second fixing plate 401. One end of the straight connecting rod 404 away from the rocking plate 403 is hinged to the head end of the ball eye joint 405 through a rotating shaft on one side thereof; the rod end of the ball eye joint 405 is threadedly connected to one end of the pressing rod 406.

[0059] As can be seen from the above, by driving the stepping motor 402, the rocker plate 403 is driven to rotate. The rocker plate 403 drives the straight connecting rod 404 to make a rotational movement with the eccentric rotating shaft as the center point. One end of the straight connecting rod 404 connected to the spherical eye joint 405 makes a planar compound movement under the drive of the end of the straight connecting rod 404 connected to the rocker plate 403, thereby driving the spherical eye joint 405 to make an up-and-down swinging movement with the hinge point between it and the straight connecting rod 404 as the center; and the pressure rod 406 is driven by the spherical eye joint 405 and is also limited by the limiting block 407 at the same time. The pressure rod 406 makes a reciprocating lifting movement along the limiting hole of the limiting block 407, and makes a regular reciprocating pressing action on the upper spring 9 on the workpiece fixture at the strong pressing station 104. Every time the stepping motor 402 rotates one circle, the pressure rod 406 makes a reciprocating lifting movement once, and the pressure rod 406 makes a strong pressing action on the upper spring 9 on the workpiece fixture at the strong pressing station 104 once. After the upper spring 9 undergoes a set number of strong pressing actions, the strong pressing treatment process is completed.

[0060] The resistance detection mechanism 5 includes a third fixing plate 501, a detection cylinder 502 and a pressure head 503. The third fixing plate 501 is fixedly installed above the workbench 101 by bolt connection.

The pressure head 503 is fixedly installed at the push rod end of the detection cylinder 502 by bolt connection. The lower end of the pressure head 503 is located above the workpiece fixture at the resistance detection station 105.

[0061] As can be seen from the above, by driving the detection cylinder 502, the pressure head 503 is driven to move downward by a certain distance to press the upper spring 9 on the workpiece fixture at the resistance detection station 105. At this time, the detection equipment is used to detect the resistance of the upper spring 9, and the resistance measurement process is completed.

[0062] The screening and partitioning mechanism 6 includes a double-layer arc-shaped frame 601, a first blanking cylinder 602, a second blanking cylinder 603, a third blanking cylinder 604, a fourth blanking cylinder 605, a fifth blanking cylinder 606, a sixth blanking cylinder 607, a seventh blanking cylinder 608, a blanking head 609 and a storage box 610.

[0063] The double-layer arc-shaped frame 601 is fixedly installed above the workbench 101 by bolt connection; the double-layer arc-shaped frame 601 is located outside the disk 102 corresponding to the first blanking station 106 to the seventh blanking station 112.

[0064] On the upper layer of the double-layer arc-shaped rack 601, a first blanking cylinder 602, a second blanking cylinder 603... a sixth blanking cylinder 607 and a seventh blanking cylinder 608 are respectively arranged at positions corresponding to the first blanking station 106, the second blanking station 107... the sixth blanking station 111 and the seventh blanking station 112; a blanking head 609 is fixedly connected to the push rod end of each blanking cylinder through bolts.

[0065] As can be seen from the above, the screening and partitioning mechanism 6 is provided with a blanking cylinder and a storage box 610 at each blanking station. Each blanking station corresponds to a certain range of upper spring resistance values, and the upper springs are stored in partitions. After the upper spring 9 has been measured for its resistance, when it rotates to the blanking station corresponding to the corresponding resistance value range, the blanking cylinder is driven. The blanking cylinder drives the blanking head 609 to move, and the blanking head 609 pushes the upper spring 9 from the workpiece fixture to the storage box 610 at the corresponding position of the station for storage, thus realizing the sorting process of the upper spring.

[0066] The control system includes a programmable logic controller, a proximity sensor 7 and a pressure sensor 8.

[0067] The proximity sensor 7 is threadedly engaged with the upper end of one side of the second fixed plate 401 through a bracket; the proximity sensor 7 is located above the straight connecting rod 404. In the strong pressing process, the number of strong presses on the upper spring 9 is set according to actual needs, and the detection distance between the proximity sensor 7 and the straight connecting rod 404 is set manually. Each time the stepping motor 402 rotates one circle, the straight connecting rod 404 rotates in position and triggers the proximity sensor 7 signal once. Thus, the number of strong presses is detected and data is fed back through the proximity sensor 7.

[0068] The pressure sensor 8 is arranged at one end of the pressure head 503 away from the detection cylinder 502. The pressure sensor 8 is applied in the resistance detection mechanism 5. When the pressure head 503 presses the upper spring 9, it is used as a detection device to detect the resistance value of the upper spring 9.

[0069] The programmable logic controller is electrically connected to a cam divider 201, a vibrating bowl 301, a pusher cylinder 304, a lifting cylinder 306, a stepping motor 402, a detection cylinder 502, a first blanking cylinder 602, a second blanking cylinder 603, a third blanking cylinder 604, a fourth blanking cylinder 605, a fifth blanking cylinder 606, a sixth blanking cylinder 607, and a seventh blanking cylinder 608 through a drive circuit and / or a relay. The programmable logic controller is electrically connected to a proximity sensor 7 and a pressure sensor 8. The utility model realizes the automated serial operation of the upper pin spring 9 in the feeding process, the stress relieving process, the resistance measurement process, and the sorting process through the programmable logic controller, thereby realizing the automated resistance detection operation of the upper pin spring 9. Compared with the traditional solution, the utility model replaces the single repetitive and regular operation actions of manual labor in the stress relieving process and the resistance measurement process, and also replaces the operation of manual labor in the sorting process, effectively reducing the labor intensity of workers, reducing the labor cost, improving the work efficiency, and reducing the probability of sorting errors.

[0070] Specific usage mode and function of this embodiment:

[0071] First, the programmable logic controller drives the vibrating bowl 301 to convey the first upper pin spring 9 to the guide groove 303 through the feed port 3031; then the programmable logic controller drives the pusher cylinder 304 to extend the push rod, driving the push plate 305 to push the upper pin spring 9 along the track of the guide groove 303 to the workpiece fixture at the loading station 103, fixing the upper pin spring 9 on the workpiece fixture, and completing the feeding of the upper pin spring 9; thereafter, the programmable logic controller drives the lifting cylinder 306 to retract the push rod, driving the pusher cylinder 304 to lift, then controlling the push rod of the pusher cylinder 304 to retract and reset, and then controlling the push rod of the lifting cylinder 306 to extend and reset, so that the pusher cylinder 304 returns to the original working point; wherein, during the process when the pusher cylinder 304 is lifted, the programmable logic controller simultaneously drives the vibrating bowl 301 to convey a new upper pin spring 9 into the guide groove 303, and the programmable logic controller also simultaneously drives the cam divider 201 to rotate once, rotating the first upper pin spring 9 to the stress relieving station 104, and at the same time, the loading station 103 enters a new workpiece fixture without a workpiece.

[0072] In this embodiment, it is set that the upper spring 9 is strongly pressed four times. After the upper spring 9 enters the strong pressing station 104, the programmable logic controller drives the stepping motor 402 to act. Through transmission, the pressure rod 406 reciprocates up and down four times to strongly press the upper spring 9 four times. Among them, the straight connecting rod 404 triggers the proximity sensor 7 once every rotation. The proximity sensor 7 sends a signal to the programmable logic controller. When the programmable logic controller counts four times, it sends a signal to control the stepping motor 402 to stop working, and the strong pressing process of the upper spring 9 ends. While the upper spring 9 at the strong pressing station 104 is being strongly pressed, the feeding station 103 is performing the above-mentioned feeding operation repeatedly to complete the feeding process of the new upper spring 9. After both are completed, the programmable logic controller drives the cam divider 201 to rotate once again, rotating the upper spring 9 that has completed the strong pressing process to the resistance detection station 105, rotating the upper spring 9 that has completed the feeding process to the strong pressing station 104, and the feeding station 103 enters a new workpiece fixture without workpieces.

[0073] After the upper spring 9 enters the resistance detection station 105, the programmable logic controller drives the detection cylinder 502 to extend the push rod, driving the pressure head 503 to move downward a certain distance to press the upper spring 9 on the workpiece fixture at the resistance detection station 105. At this time, the pressure sensor 8 detects the resistance value of the upper spring 9 and feeds it back to the programmable logic controller for storage. After receiving the resistance value, the programmable logic controller controls the detection cylinder 502 to reset, retracting the push rod and driving the pressure head 503 to move upward and reset, completing the resistance measurement process of the upper spring 9. While the upper spring 9 at the resistance detection station 105 is being measured for resistance, the feeding station 103 and the strong pressing station 104 are respectively performing the above-mentioned feeding operation and strong pressing operation repeatedly to complete the feeding process and strong pressing process of the subsequent upper spring 9. After the feeding station 103, the strong pressing station 104, and the resistance detection station 105 have all completed their operations, the programmable logic controller drives the cam divider 201 to rotate once again, rotating the upper spring 9 that has completed the resistance detection station 105 to the first blanking station 106, rotating the upper spring 9 that has completed the strong pressing process to the resistance detection station 105, rotating the upper spring 9 that has completed the feeding process to the strong pressing station 104, and the feeding station 103 enters a new workpiece fixture without workpieces.

[0074] After the upper spring 9 enters the sorting process, since there are seven blanking stations, each blanking station corresponds to a different resistance value range;

[0075] When the resistance value of the upper pin spring 9 at the first blanking station 106 is within the resistance value range corresponding to the first blanking station 106, the programmable logic controller drives the first blanking cylinder 602 to act, retract the push rod, drive the blanking head 609 to move, and the blanking head 609 pushes the upper pin spring 9 on the workpiece fixture at the first blanking station 106 into the corresponding storage box 610 at the first blanking station 106 for storage; after storage, the programmable logic controller drives the first blanking cylinder 602 to reset, extend the push rod, drive the blanking head 609 to move back to its original position, and complete the sorting; during the sorting process, the loading station 103, the strong pressing station 104, and the resistance detection station 105 are respectively performing the above-mentioned loading operation, strong pressing operation, and resistance measurement actions, and each completes the loading process, strong pressing process, and resistance measurement process of the subsequent upper pin spring 9; after the loading station 103, the strong pressing station 104, the resistance detection station 105, and the first blanking station 106 have all completed their operations, the programmable logic controller drives the cam divider 201 to rotate once again. The workpiece fixture unloaded at the first blanking station 106 rotates to the second blanking station 107, waits for the subsequent cyclic rotation to the loading station 103 to start a new round of operations, completes the rotation of the upper pin spring 9 at the resistance detection station 105 to the first blanking station 106, the rotation of the upper pin spring 9 that has completed the strong pressing process to the resistance detection station 105, the rotation of the upper pin spring 9 that has completed the loading process to the strong pressing station 104, and the loading station 103 receives a new workpiece fixture without a workpiece.

[0076] When the resistance value of the upper pin spring 9 at the first blanking station 106 is not within the resistance value range corresponding to the first blanking station 106, after the programmable logic controller controls the loading mechanism 3, the strong pressing device 4, and the resistance detection mechanism 5 to repeat the above-mentioned process actions at the loading station 103, the strong pressing station 104, and the resistance detection station 105 respectively, the programmable logic controller drives the cam divider 201 to rotate once again, so that the upper pin spring 9 enters the second blanking station 107. When the resistance value of the upper pin spring 9 is within the resistance value range corresponding to the second blanking station 107, repeat the above-mentioned blanking action, blank the upper pin spring 9 into the corresponding storage box 610 at the second blanking station 107 for storage, and complete the sorting; when the resistance value of the upper pin spring 9 is not within the resistance value range corresponding to the second blanking station 107, wait until the processes at the loading station 103, the strong pressing station 104, and the resistance detection station 105 are completed, and then transfer the upper pin spring 9 to the third blanking station 108. Repeat this cycle until the upper pin spring 9 is rotated to the blanking station corresponding to its resistance value range for the blanking action, completing a resistance detection cycle of an upper pin spring; subsequent upper pin springs perform the same actions and repeat this cycle.

[0077] As can be seen from the above, the utility model realizes the automated resistance detection operation of the upper pin spring. Compared with the prior art, it replaces the single repetitive and regular operation actions of manual labor in the two processes of strong pressure treatment and resistance measurement, and also replaces the operation of manual labor in the sorting process, effectively reducing the labor intensity of workers, reducing labor costs, improving work efficiency, and reducing the probability of errors in sorting.
