Description

Technical Field

[0001] This utility model relates to the field of indexing technology for grooving machines, and specifically to a high-precision indexing mechanism for grooving machines. Background Technology

[0002] A grooving machine is a specialized single-slot punching device used for punching slots in motor rotor or stator iron cores. The punching die for the motor rotor or stator iron core is installed between the punch and the worktable. The reciprocating motion of the punch drives the upper die to reciprocate up and down. The iron core to be grooved is installed on an indexing device with intermittent motion. The indexing device makes the iron core rotate according to preset requirements. When the punch moves downward, the iron core does not rotate and waits for grooving. When the punch moves upward, the iron core rotates and indexes. After one revolution of indexing motion, the grooving process of one iron core can be completed. Currently, CNC grooving machines use servo motors to drive the indexing spindle through two-stage gear transmission or one-stage gear transmission, or directly drive the indexing spindle to rotate by a servo motor, thereby achieving high-precision indexing processing.

[0003] During the indexing and grooving process, the indexing component needs to slide longitudinally to determine the longitudinal sliding distance of the grooving component, thus achieving high-precision grooving to a specified depth. However, in actual grooving, although high-precision grooving can be achieved through servo motors, it is difficult to visually observe the grooving depth and progress from all four directions around the grooving position. This makes it difficult for on-site personnel to directly observe the grooving depth and progress with their naked eyes, requiring them to constantly check the servo motor's control platform, making high-precision operation cumbersome.

[0004] Therefore, it is necessary to invent a high-precision indexing mechanism for a grooving machine to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a high-precision indexing mechanism for a grooving machine. This mechanism solves the problem that in existing technologies, it is difficult to visually observe the grooving depth and progress from all four directions around the grooving position. This makes it difficult for on-site personnel to directly observe the grooving depth and progress with the naked eye, requiring them to constantly monitor the servo motor's control platform, thus making high-precision operation cumbersome.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-precision indexing mechanism for a grooving machine includes a top plate, a bottom plate located directly below the top plate, an indexing component installed at the center of the bottom end of the top plate and capable of longitudinal sliding for indexing, and a grooving component detachably installed at the bottom end of the indexing component. The bottom plate has a square groove at its center for grooving by the grooving component. Straight plates are detachably installed at the bottom end of the top plate around the indexing component. Each straight plate has a vertical groove with an open bottom end. The telescopic part of the indexing component is detachably engaged with a linkage rod, the number of which is the same as the number of straight plates. A sliding indicator block capable of sliding longitudinally along the vertical groove is installed at the other end of each linkage rod. Multiple scale bars indicating the longitudinal sliding distance of the sliding indicator block are installed on the side of the straight plate away from the indexing component, and the multiple scale bars are located on both sides of the vertical groove.

[0008] As a preferred embodiment of this utility model, a column is detachably installed in the vertical groove, and the sliding indicator block is longitudinally slidably sleeved on the column.

[0009] As a preferred embodiment of this utility model, a chuck is detachably sleeved in the middle of the telescopic part of the indexing component, a stop plate is installed at the bottom end of the linkage rod, a locking post that can be longitudinally inserted into the chuck is installed at the bottom end of the stop plate, and the bottom surface of the stop plate abuts against the top surface of the chuck.

[0010] As a preferred embodiment of this utility model, an indexing seat is installed at the center of the bottom end of the top plate, and the indexing component is detachably installed at the center of the bottom surface of the indexing seat.

[0011] As a preferred embodiment of this utility model, straight rods are installed at the four corners of the bottom end of the top plate, and the bottom ends of the multiple straight rods are detachably connected to the top surface of the bottom plate.

[0012] As a preferred embodiment of this utility model, the base plate has multiple transverse grooves, and multiple mounting seats are installed on the bottom surface of the base plate. A telescopic member that can be extended laterally is installed on the side of the mounting seat near the square groove. A support block is installed on the other end of the telescopic member through a connecting seat. The top surface of the support block is flush with the top surface of the base plate, and a guide rod that can slide laterally along the transverse groove is installed on the side of the support block.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] In this invention, the longitudinal sliding of the indexing component drives the longitudinal movement of the grooving component to perform grooving on a square-grooved plate. High precision is achieved by the indexing component controlled by a servo motor. During the process of controlling the grooving depth of the grooving component by the longitudinal sliding of the telescopic part of the indexing component, multiple linkage rods drive the sliding indicator block to slide synchronously longitudinally within the vertical grooves of multiple straight plates around the plate. The grooving depth and progress of the grooving component can be visually observed around the grooving position through the scale bar. In other words, the grooving depth of the grooving component can be observed by observing the longitudinal sliding position of the sliding indicator block along the scale bar. Finally, after a single high-precision grooving setting of the indexing component, on-site personnel can intuitively observe the grooving depth and progress by observing the longitudinal position of the sliding indicator block at the scale bar, avoiding the need to constantly check the operation platform of the servo motor and reducing the repeated operation of high-precision grooving.

[0020] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0021] This utility model provides, for example Figure 1-3The high-precision indexing mechanism of the punching machine shown includes a top plate 1, a bottom plate 3 located directly below the top plate 1, an indexing component 5 installed at the center of the bottom end of the top plate 1 and capable of longitudinal sliding for indexing, and a punching component 6 detachably installed at the bottom end of the indexing component 5. The bottom plate 3 has a square groove 7 in the center for the punching component 6 to perform punching. Straight plates 9 are detachably installed at the bottom end of the top plate 1 around the indexing component 5. Vertical grooves 10 with open bottom ends are opened in the straight plates 9. The telescopic part of the indexing component 5 is detachably snapped with a linkage rod 13 in the same number as the straight plates 9. The other end of the linkage rod 13 is equipped with a sliding indicator block 14 that can slide longitudinally along the vertical groove 10. Multiple scale bars 16 that indicate the longitudinal sliding distance of the sliding indicator block 14 are installed on the side of the straight plate 9 away from the indexing component 5. The multiple scale bars 16 are located on both sides of the vertical groove 10. The longitudinal sliding process of the indexing component 5 is controlled with high precision by a servo motor, which is a mature prior art in this field.

[0022] A column 15 is detachably installed inside the vertical groove 10. A sliding indicator block 14 is longitudinally slidably sleeved on the column 15. During the longitudinal sliding of the sliding indicator block 14 along the vertical groove 10, the sliding indicator block 14 simultaneously slides longitudinally along the column 15, thereby improving the smoothness and accuracy of the longitudinal sliding of the sliding indicator block 14.

[0023] The indexing component 5 has a chuck 8 detachably fitted in the middle of its telescopic part. The bottom end of the linkage rod 13 is fitted with a stop plate 12. The bottom end of the stop plate 12 is fitted with a locking pin 11 that can be inserted longitudinally into the chuck 8. The bottom surface of the stop plate 12 abuts against the top of the chuck 8. When the linkage rod 13 needs to be disassembled, the locking pin 11 can be pulled out longitudinally upward in the chuck 8.

[0024] A dividing seat 4 is installed at the center of the bottom end of the top plate 1. The dividing component 5 is detachably installed at the center of the bottom surface of the dividing seat 4. The dividing seat 4 can provide the mounting and bearing position between the dividing component 5 and the top plate 1.

[0025] Straight rods 2 are installed at the four corners of the bottom of the top plate 1. The bottom ends of multiple straight rods 2 are detachably connected to the top surface of the bottom plate 3. The length of the straight rods 2 depends on the overall longitudinal sliding length of the indexing component 5.

[0026] Multiple transverse grooves 21 are provided in the base plate 3. Multiple mounting seats 17 are installed on the bottom surface of the base plate 3. A telescopic member 18 that can be extended laterally is installed on the side of the mounting seat 17 near the square groove 7. A support block 20 is installed on the other end of the telescopic member 18 through the connecting seat 19. The top surface of the support block 20 is flush with the top surface of the base plate 3. A guide rod 22 that can slide laterally along the transverse groove 21 is installed on the side of the support block 20. The telescopic member 18 extends laterally, thereby changing the spacing between the multiple support blocks 20, thereby providing support for the plates to be punched of different sizes from all sides.

[0027] In this invention, the longitudinal sliding of the indexing component 5 drives the longitudinal movement of the grooving component 6 to perform grooving on the plate with square grooves 7. High precision is achieved by the indexing component 5 controlled by a servo motor. During the process of controlling the grooving depth of the grooving component 6 by the longitudinal sliding of the telescopic part of the indexing component 5, multiple linkage rods 13 drive the sliding indicator block 14 to slide synchronously longitudinally within the vertical grooves 10 of multiple straight plates 9 around the perimeter. The grooving depth and progress of the grooving component 6 can be visually observed around the grooving position through the scale bar 16. In other words, the grooving depth of the grooving component 6 can be observed by observing the longitudinal sliding position of the sliding indicator block 14 along the scale bar 16. Finally, after a single high-precision grooving setting of the indexing component 5, the on-site personnel can visually observe the grooving depth and progress by observing the longitudinal position of the sliding indicator block 14 at the scale bar 16, avoiding the need to constantly check the operation platform of the servo motor and reducing the repeated operation of high-precision grooving.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
