Description

Technical Field

[0001] The invention relates to the technical field of motor core processing, and in particular to a high-speed notching device with integrated notching and indexing. Background Art

[0002] The slot punching machine is a special single slot punching equipment used to punch slots for motor rotor or stator iron core sheets. The die for punching motor rotor or stator iron core sheets is installed between the punch and the workbench. The up and down reciprocating motion of the punch drives the upper die to reciprocate up and down. The iron core sheets that need to be slotted are installed on a dividing device with intermittent motion, and the dividing device is used to make the iron core sheets rotate according to the preset requirements. When the punch moves downward, the iron chip does not rotate and waits for notching. When the punch moves upward, the iron chip rotates and indexes. After one week of indexing movement, the notching process of one iron chip can be completed. The existing notching device is a dividing box and a machine body arranged together. The friction pressure will cause the dividing box to crawl on the machine body. The workpiece will vibrate and deflect on the dividing box during high-speed notching, affecting the product accuracy during punching. For example, the high-speed notching machine with patent number CN103949526B connects the dividing box and the guide arm by using a rolling sliding pair. Since the friction of the rolling sliding pair is fixed and easy to control, precise displacement control of the dividing box on the guide arm is achieved, making the cutting of the sample more accurate.

[0003] However, during the notching process, the workpiece is fixed on a dividing box, which is driven by the dividing box to rotate, and the notching machine is used to perform notching. In the process of the dividing box driving the workpiece to rotate at high speed, the workpiece is prone to vibrate due to excessive rotation speed and the high notching frequency. The workpiece itself will vibrate due to the rapid impact, resulting in poor stability during notching. In addition, the workpiece will slip against the dividing plate due to excessive rotation speed, affecting the notching accuracy of the workpiece.

[0004] Therefore, a high-speed notching device with integrated notching and indexing is proposed. Summary of the invention

[0036] Specifically, the filling component 101 includes a pressing rack 1011, a filling gear 1013, a filling rack 1012, a filling platform 1014 and a repeating unit 1015. The pressing rack 1011 is fixed to the outer wall of the pressing cover 6, the filling gear 1013 is rotatably connected to the side of the outer shell 2, the pressing rack 1011 is away from the center of the pressing cover 6 and is meshed with the filling gear 1013 near the center of the pressing cover 6.

[0037] Specifically, the repetitive unit 1015 includes a filling guide rod 10151, a filling sleeve 10153 and a filling spring 10152. The filling guide rod 10151 is fixed on the filling platform 1014. The filling sleeve 10153 is slidably connected to the filling guide rod 10151, and its sliding direction is up and down. The filling sleeve 10153 is fixedly connected to the side of the filling block 4, and the two ends of the filling spring 10152 are respectively abutted against the lower end of the filling sleeve 10153 and the filling platform 1014.

[0038] Working principle: When it is necessary to punch a groove on the workpiece, the operator only needs to place the workpiece in the center of the tray 7 so that the center of the workpiece is aligned with the rotation center of the punch head 8, and then operate the cylinder to push the down-pressing cover 6 and the down-pressing baffle 31 to move downward and squeeze the down-pressing spring 33 until the lower end of the down-pressing cover 6 fits against the workpiece, so that the down-pressing cover 6 and the tray 7 cooperate to clamp the workpiece. At this time, the outer locking groove 344 on the down-pressing cover 6 is horizontal with the locking block 343, and the locking block 343 is rotated into the outer locking groove 344 under the action of the torsion spring to lock the down-pressing cover 6, and then the cylinder moves up and resets.

[0039] At the same time, in the process of the lower pressure cover 6 moving downward, the lower pressure cover 6 drives the lower pressure rack 1011 to move downward synchronously, so that the lower pressure rack 1011 drives the filling gear 1013 to rotate, and the filling gear 1013 rotates to drive the filling rack 1012, the filling table 1014 and the filling block 4 to move toward the center of the shell 2 until the lower pressure cover 6 is attached to and locked with the workpiece. At this time, the filling block 4 is completely moved to the top of the dividing table 94 on the punching head 8, and then the notching machine 2121 starts to work and drives the pressure rod 1 to move up and down repeatedly, so that when the pressure rod 1 moves downward, it drives the filling block 4 to move downward and squeeze the filling spring 10152. The filling block 4 moves downward and drives the dividing table 94 and the punching head 8 to move downward to punch the workpiece, so that during the notching process of the notching machine 2121, the workpiece can be completely compacted on all sides, and it is ensured that when punching, the punching head 8 and the workpiece are punched in an environment where the lower pressure cover 6 is isolated from the outside, thereby ensuring stability during punching and preventing foreign objects from flying in or accidental touch by personnel during punching.

[0040] Example 2

[0041] See also Figures 5 to 12, a high-speed notching device with integrated notching indexing is provided, including an indexing component 9, the indexing component 9 includes an indexing die 91, an upward moving block 92, a lateral moving block 93, an indexing table 94, an indexing block 95 and an indexing spring 96, a gasket is arranged at the lower end or the upper end of the indexing spring 96, the gasket rotates synchronously with the indexing table 94, the indexing die 91 is fixedly connected in the housing 2, the upward moving block 92 is longitudinally arranged at the bottom of the indexing die 91, an upward chamfer 921 is arranged at the upper end of the upward moving block 92, the lateral moving block 93 is arranged at the upper end of the upward moving block 92, the indexing table 94 is fixed to the upper end of the lower pressure head, the indexing table 94 is rotatably connected with the upward moving block 92 and the lateral moving block 93, the two ends of the indexing spring 96 abut against the lower end of the indexing table 94 and the inner wall of the indexing die 91, and the indexing block 95 is fixed to the side of the indexing table 94, The indexing block 95 cooperates with the upper block 92, the transverse block 93 and the upper chamfer 921. The transverse block 93 includes a transverse section and a blocking section. The upper block 92 and the transverse block 93 are provided with multiple groups. The upper block 92, the transverse block 93 and the punching groove 71 are the same in number and have corresponding positions. The cooperation here means that when the indexing block 95 moves downward under the drive of the indexing table 94, the indexing block 95 first moves downward along the blocking section of the transverse block 93 for a distance. As the indexing block 95 continues to move downward, the lower end of the indexing block 95 fits with the upper chamfer 921 of the upper block 92, and rotates to the side of the upper block 92 along the upper chamfer 921, and moves downward along the side of the upper block 92, so that the punching head 8 cooperates with the punching groove 71 on the tray 7 to punch the workpiece;

[0042] Specifically, when the pressure rod 1 moves upward, the indexing table 94 is reset and moved upward under the action of the indexing spring 96, so that the indexing block 95 first moves upward along the side of the upper block 92 until the indexing block 95 moves to the top of the upper block 92, and the indexing block 95 is fitted with the lower end of the transverse section of the next transverse block 93. At this time, the indexing block 95 moves upward and rotates along the next transverse section, and finally the indexing block 95 moves to the blocking section of the next transverse block 93 and stops, waiting for the next downward movement of the pressure rod 1.

[0043] Specifically, an end cover 21 is provided at the lower end of the shell 2, and the end cover 21 is connected to the bottom of the shell 2 by bolts, and the upper end of the end cover 21 abuts against the dividing die 91, and the dividing die 91 is detachably connected to the shell 2. After the dividing die 91 and the shell 2 are fixed by the end cover 21, the dividing die 91 can neither rotate nor slide up and down in the shell 2. When different workpieces need to be processed, the operator can remove the end cover 21 and then replace different dividing dies 91, dividing plates, dividing tables 94 and punching heads 8 to meet different processing requirements. A roller (not shown in the figure) is rotatably connected to the dividing block 95, and the roller cooperates with the upper block 92, the transverse block 93 and the upper chamfer 921. The roller can reduce the friction between the dividing block 95 and the upper block 92, the transverse block 93 and the upper chamfer 921.

[0044] The rest of the structure is the same as that of Example 1.

[0045] Working principle: After the lower pressure cover 6 clamps the workpiece on the tray 7, when the pressure rod 1 of the notching machine 2121 works to punch, the pressure rod 1 moves downward to drive the filling block 4 to move downward to extrude the indexing table 94, so that the indexing table 94 drives the indexing block 95 and the punching head 8 to move downward to punch the workpiece. In the process of the indexing table 94 and the indexing block 95 moving downward, the indexing block 95 first moves downward for a distance along the blocking section of the transverse block 93. As the indexing block 95 continues to move downward, the lower end of the indexing block 95 fits with the upper chamfer 921 of the upper block 92, and rotates along the upper chamfer 921 to the side of the upper block 92, and moves downward along the side of the upper block 92, so that the punching head 8 cooperates with the punching groove 71 on the tray 7 to punch the workpiece. When the pressure rod 1 moves upward, the indexing table 94 Under the action of the indexing spring 96, it resets and moves upward, so that the indexing block 95 first moves upward along the side of the upper block 92 until the indexing block 95 moves to the top of the upper block 92, and the indexing block 95 is fitted with the lower end of the lateral section of the next lateral block 93. At this time, the indexing block 95 moves upward along the next lateral section and rotates, and finally the indexing block 95 moves to the blocking section of the next lateral block 93 and stops, waiting for the next downward punching of the pressure rod 1, so that the notching machine 2121 can drive the pressure rod 1 to punch grooves. The indexing table 94 can automatically drive the punching head 8 to rotate, so as to realize the notching of the workpiece, so that the workpiece does not need to be rotated during the rapid notching process, thereby ensuring the stability of the workpiece during notching, and preventing the workpiece and the pallet 7 from being offset due to unstable clamping or too fast rotation speed during notching, thereby affecting the processing accuracy.

[0046] Example 3

[0047] See also Figures 5 to 12, a high-speed notching device with integrated notching indexing is provided, including a reset component 5, the reset component 5 includes a reset spring 51, a reset rod 52 and a reset chamfer 53, both ends of the reset spring 51 are respectively abutted against the lower end of the indexing block 95 and the inside of the shell 2, the reset rod 52 is arranged at the upper end of the locking block 343, the reset chamfer 53 is arranged on both sides of the locking block 343, the indexing block 95 cooperates with the end of the locking block 343 close to the center of the shell 2, and the cooperation here means that when the indexing block 95 rotates one circle along the upper block 92 and the transverse block 93 of the indexing die 91, and the indexing block 95 returns to the transverse section of the transverse block 93 where the notching is started, the indexing block 95 moves transversely along the transverse section until it abuts against the blocking section. In this process, the indexing block 95 and the locking block 343 located here The end contacts, driving the locking block 343 to overcome the torsion spring torsion force, and causing the locking block 343 to rotate along the limiting cylinder 342 until the indexing block 95 abuts against the blocking section. At this time, the locking block 343 is still in contact with the indexing block 95, and the locking block 343 is rotated out of the outer locking groove 344 of the lower pressure cover 6 away from one end of the indexing block 95, and the reset chamfer 53 cooperates with the filling block 4. The cooperation here means that when the filling block 4 moves to the reset rod 52, the filling block 4 can fit with the reset chamfer 53 and push the locking block 343 downward along the reset chamfer 53. While the locking block 343 squeezes the locking spring downward, the locking block 343 moves to the lower end of the indexing block 95 and rotates to the other side of the indexing block 95 under the action of the torsion spring, so that the locking block 343 does not abut against the indexing block 95.

[0048] The remaining structures are the same as those in Example 2.

[0049] Working principle: After punching a circle of grooves on the workpiece, when the indexing block 95 returns to the lateral movement section of the lateral movement block 93 where the groove was started, the indexing block 95 moves horizontally along the lateral movement section until it abuts against the blocking section. In this process, the indexing block 95 contacts the end of the locking block 343 located here, driving the locking block 343 to overcome the torsion force of the torsion spring and causing the locking block 343 to rotate along the limiting cylinder 342 until the indexing block 95 abuts against the blocking section. At this time, the locking block 343 is still in contact with the indexing block 95, and the locking block 343 is away from the indexing block. One end of the block 95 is rotated out of the outer locking groove 344 of the lower pressing cover 6 to complete the unlocking of the lower pressing cover 6. The lower pressing cover 6 moves upward and resets under the action of the lower pressing spring 33. When the lower pressing cover 6 moves upward, it drives the lower pressing rack 1011 to move upward. Under the action of the filling gear 1013 and the filling rack 1012, the lower pressing rack 1011 drives the filling block 4 to move out between the pressure rod 1 and the indexing table 94. When the filling block 4 moves outward, when the filling block 4 moves to the reset rod 52, the filling block 4 can be locked with the reset rod 52. The chamfer 53 fits well, and the locking block 343 is pushed downward along the reset chamfer 53. While the locking block 343 presses the locking spring downward, the locking block 343 moves to the lower end of the indexing block 95 and rotates to the other side of the indexing block 95 under the action of the torsion spring, so that the locking block 343 does not abut against the indexing block 95, and the end of the locking block 343 away from the indexing block 95 fits the inner wall of the downward pressure cover 6. After the downward pressure spring 33 is completely reset, the filling block 4 is separated from the fit with the upper end of the reset block, and the locking block 343 is in the locking spring. It resets upward under the action of the spring, waiting to lock the lower pressure cover 6 next time. Reset chamfers 53 are provided on both sides of the reset block. This is to ensure that the reset block can pass smoothly when passing through this place when the lower pressure cover 6 moves down next time. The integrated high-speed notching device for notching and indexing can ensure the stability of the workpiece when notching, and enable the punching head 8 to automatically rotate and index. At the same time, after the notching is completed, the lower pressure cover 6 can be automatically opened to facilitate the removal of the workpiece and the next use, with a higher automation effect.

[0050] After the pressure cover 6 is opened, the operator takes the workpiece out of the pallet 7. At this time, there is no direct contact between the pressure rod 1 and the dividing table 94 due to the lack of filling block 4. Therefore, when the operator takes out the workpiece, even if the notching machine 2121 is started by mistake, the punching head 8 will not be pressed down, ensuring the safety of the workpiece when it is taken out and fed in, and greatly improving the safety of the notching processing of the workpiece.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
