As an important structural component, the processing quality of composite material wheel discs directly affects the performance and safety of the entire product. Drilling is a common process in the processing of composite material wheel discs.

[0003] Chinese patent provides a drilling device based on a mechanical gear disk, publication number CN217799078U, which includes a base, a support column fixedly installed on the top of the base, a support plate fixedly connected to one end of the support column, fixing rods fixedly installed on both sides of the support plate, a processing plate fixedly connected to one end of the fixing rods, a slot opened on the top of the processing plate, a positioning pad fixedly installed on the upper surface of the processing plate, a fixing block connected to the surface of the fixing rods, and a small electric push rod fixedly installed on one side of the fixing block.

[0004] The aforementioned device can improve drilling efficiency by fixing the wheel, but it only clamps and fixes the outer surface of the wheel, resulting in poor positioning. It is prone to shaking during drilling, which affects drilling accuracy. In addition, it cannot flexibly replace the drill bit according to drilling requirements. Therefore, a composite material wheel drilling positioning device is needed. Utility Model Content

[0005] The purpose of this invention is to provide a composite material wheel drilling positioning device to solve the problems of poor positioning and fixing effect of existing devices and inconvenience in flexibly changing drill bits.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a composite material wheel drilling positioning device, comprising a base, a bracket, a hydraulic cylinder, a drilling motor, and a drill bit. A positioning mechanism is provided on the base, and a disassembly and assembly mechanism is provided between the drilling motor and the drill bit. The positioning mechanism includes a processing table fixedly mounted on the base, a servo motor positioned below the processing table, a driving bevel gear fixedly mounted on the shaft of the servo motor, a movable groove formed at the bottom of the processing table, and a sliding groove formed on the processing table. A screw is rotatably mounted within the sliding groove, and one end of the screw rotatably extends through the sliding groove into the movable groove and is fixedly connected to a driven bevel gear. The gear meshes with the driving bevel gear. A movable block, threadedly connected to the screw, is slidably connected within the groove. An arc-shaped top block is fixedly mounted on the movable block. The disassembly and assembly mechanism includes a mounting block fixedly mounted on the drilling motor shaft and a fixing block fixedly mounted on the drill bit. The fixing block has a fixing hole. The bottom of the mounting block has a slot for insertion into the fixing block. A slot has a groove. One side of the mounting block has a groove. A cylinder is fixedly mounted within the groove. A slider is slidably connected within the cylinder. A locking rod, adapted to the fixing hole and the locking groove, is fixedly mounted on one side of the slider. A guide rod is fixedly mounted on the other side of the slider. A spring is sleeved on the guide rod.

[0007] Preferably, the base has a mounting slot, and the servo motor is fixedly mounted in the mounting slot.

[0008] Preferably, a fixing plate is fixedly installed on the base, and an electric push rod is fixedly installed on one side of the fixing plate. The output rod of the electric push rod slides through the fixing plate and is fixedly connected to an arc-shaped clamping block.

[0009] Preferably, anti-slip pads are fixedly provided on both the arc-shaped top block and the arc-shaped clamping block.

[0010] Preferably, the spring is fixedly disposed between the cylinder and the slider, and the end of the guide rod away from the slider slides through the cylinder and is fixedly connected to a pull ring.

[0011] Preferably, the locking rod slides through the cylinder and passes through the fixing hole to engage with the locking groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) The composite material wheel drilling and positioning device starts the servo motor to drive the active bevel gear to rotate multiple driven bevel gears that mesh with it. The driven bevel gears drive the screw to rotate, so that the moving block that is threaded to the screw can drive the arc-shaped top block to move along the slide groove until the four arc-shaped top blocks are tightly attached to the inner ring wall of the wheel, thus realizing the positioning and fixing of wheel discs of different sizes. Then, the electric push rod is started to enable the two arc-shaped clamping blocks to clamp and position the outer ring surface of the wheel, further improving the fixation of the wheel.

[0014] 2) This composite material wheel drilling positioning device works by pulling the pull ring outward to cause the guide rod to move the locking rod away from the slot and fixing hole via the slider. Then, the fixing block on the drill bit is pulled out of the slot of the mounting block to complete the removal of the drill bit. Pulling the pull ring outward again causes the locking rod to retract. Then, the fixing block on the new drill bit is inserted into the slot of the mounting block. Then, the pull ring is released so that the locking rod automatically passes through the fixing hole and engages with the slot under the spring's rebound, thus locking and fixing the new drill bit and completing the replacement of the drill bit.

A positioning mechanism 5 is provided on the base 1, and a disassembly and assembly mechanism 6 is provided between the drilling motor 4 and the drill bit 7.

[0023] See Figure 2 and Figure 3 Furthermore, the positioning mechanism 5 includes a processing table 501 fixedly mounted on the base 1. A servo motor 503 is disposed below the processing table 501. A drive bevel gear 504 is fixedly mounted on the shaft of the servo motor 503. A movable groove 507 is formed at the bottom of the processing table 501. A sliding groove 505 is formed on the processing table 501. A screw 506 is rotatably mounted in the sliding groove 505. One end of the screw 506 rotatably extends through the sliding groove 505 into the movable groove 507 and is fixedly connected to a driven bevel gear 508. The driven bevel gear 508 and the drive bevel gear 504 are connected in a fixed manner. 4. Engaging connection: A movable block 509, which is threadedly connected to a screw 506, is slidably connected in the slide groove 505. An arc-shaped top block 510 is fixedly installed on the movable block 509. An installation groove 502 is provided on the base 1. A servo motor 503 is fixedly installed in the installation groove 502. A fixing plate 511 is fixedly installed on the base 1. An electric push rod 512 is fixedly installed on one side of the fixing plate 511. The output rod of the electric push rod 512 slides through the fixing plate 511 and is fixedly connected to an arc-shaped clamping block 513. Anti-slip stickers are fixedly installed on both the arc-shaped top block 510 and the arc-shaped clamping block 513.

[0024] Specifically, by starting the servo motor 503, the active bevel gear 504 drives the multiple driven bevel gears 508 that mesh with it to rotate. The driven bevel gears 508 drive the screw 506 to rotate, so that the moving block 509, which is threadedly connected to the screw 506, can drive the arc-shaped top block 510 to move along the slide groove 505 until the four arc-shaped top blocks 510 are tightly attached to the inner ring wall of the wheel, thus achieving the positioning and fixing of wheel discs of different sizes. After that, the electric push rod 512 is started so that the two arc-shaped clamping blocks 513 can clamp and position the outer ring surface of the wheel, further improving the fixation of the wheel.

[0025] See Figure 4 and Figure 5Furthermore, the disassembly and assembly mechanism 6 includes a mounting block 601 fixedly mounted on the shaft of the drilling motor 4 and a fixing block 602 fixedly mounted on the drill bit 7. The fixing block 602 has a fixing hole 603. The bottom of the mounting block 601 has a slot 604 for insertion into the fixing block 602. The slot 604 has a groove 612. One side of the mounting block 601 has a groove 605. A cylinder 606 is fixedly mounted in the groove 605. A slider 607 is slidably connected in the cylinder 606. A locking rod 608 adapted to the fixing hole 603 and the slot 612 is fixedly provided on one side of the slider 607. A guide rod 609 is fixedly provided on the other side of the slider 607. A spring 610 is sleeved on the guide rod 609. The spring 610 is fixedly provided between the cylinder 606 and the slider 607. The end of the guide rod 609 away from the slider 607 slides through the cylinder 606 and is fixedly connected to a pull ring 611. The locking rod 608 slides through the cylinder 606 and passes through the fixing hole 603 and engages with the slot 612.

[0026] Specifically, by pulling the pull ring 611 outward, the guide rod 609 is driven by the slider 607 to disengage the locking rod 608 from the slot 612 and the fixing hole 603. Then, the fixing block 602 on the drill bit 7 is pulled out from the slot 604 of the mounting block 601, completing the disassembly of the drill bit 7. Pulling the pull ring 611 outward again causes the locking rod 608 to retract. Then, the fixing block 602 on the new drill bit 7 is inserted into the slot 604 of the mounting block 601. Then, the pull ring 611 is released, and the locking rod 608 automatically passes through the fixing hole 603 and engages with the slot 612 under the rebound of the spring 610, thereby locking and fixing the new drill bit 7 and completing the replacement of the drill bit 7.

[0027] In actual operation, the composite material wheel to be processed is placed on the processing table 501. The servo motor 503 is started to drive the active bevel gear 504 to drive the multiple driven bevel gears 508 that are meshed with it to rotate. The driven bevel gears 508 drive the screw 506 to rotate, so that the moving block 509 threadedly connected to the screw 506 can drive the arc-shaped top block 510 to move along the slide groove 505 until the four arc-shaped top blocks 510 are tightly attached to the inner ring wall of the wheel, thus achieving the positioning and fixing of the wheel. Then, the electric push rod 512 is started to enable the two arc-shaped clamping blocks 513 to clamp and position the outer ring surface of the wheel, further improving the fixation of the wheel. The drilling motor 4 is started to rotate the drill bit 7. Then, the hydraulic cylinder 3 is controlled to adjust the lifting and moving of the drill bit 7, and the drilling operation on the wheel can begin.

[0028] When replacing drill bit 7 according to the required drilling size, pull the pull ring 611 outward to move the guide rod 609 towards the cylinder 606 via the slider 607, causing the locking rod 608 to disengage from the slot 612 and the fixing hole 603. Then, pull the fixing block 602 on drill bit 7 out of the slot 604 of the mounting block 601 to quickly disassemble drill bit 7. After replacing with a new drill bit 7, pull the pull ring 611 outward again to retract the locking rod 608. Then, insert the fixing block 602 on the new drill bit 7 into the slot 604 of the mounting block 601. Then, release the pull ring 611. Under the rebound of the spring 610, the locking rod 608 automatically passes through the fixing hole 603 and engages with the slot 612, thus locking and fixing the new drill bit 7 and completing the replacement of drill bit 7.
