Description

Technical Field

[0001] This invention relates to the field of electric drill assembly equipment technology, specifically to an automatic assembly equipment for electric drill striking blocks. Background Technology

[0002] The impact block of a power drill, as a core component for achieving impact function, plays a crucial role in drilling into hard materials such as metal and concrete. The impact block typically employs a ball-and-groove impact mechanism, consisting of a spring, balls, and a drive shaft with helical grooves. When the drill bit encounters resistance, the impact block compresses the spring along the helical grooves. As the spring rebounds, the helical grooves guide the impact block, causing axial displacement. This, combined with the motor's rotation, creates a "drilling while rotating" compound motion. During assembly, different types of balls and springs need to be fitted into the impact block base.

[0003] For example, an automatic impact block rotor device for a hand drill with publication number CN119328466A includes a bearing, a worktable, two support columns symmetrically fixed on the top of the worktable, a horizontal plate fixed between the tops of the two support columns, four uprights symmetrically fixed on the top of the worktable and located outside the horizontal plate, a sliding push assembly slidably disposed on the top of the worktable and located below the horizontal plate, a placement plate disposed on the sliding push assembly and located above the horizontal plate, and a positioning insert fixedly disposed on the top of the horizontal plate and located to the right of the placement plate.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-3 and Figures 5-8This embodiment of an automatic assembly device for a hand drill striking block includes a frame 1. A mounting plate 2 is horizontally arranged in the middle of the frame 1. A turntable conveyor mechanism 3 is rotatably connected to the middle of the mounting plate 2 for rotating and conveying the workpiece to be assembled. Several limiting mechanisms 4 are evenly fixedly connected around the edge of the turntable conveyor mechanism 3 to limit the workpiece to be assembled. A first ball assembly mechanism 5, a shim assembly mechanism 6, a spring assembly mechanism 7, a second ball assembly mechanism 8, a gear assembly mechanism 9, and a feeding mechanism 10 are sequentially arranged around the outer side of the turntable conveyor mechanism 3. The first ball assembly mechanism 5 is used to assemble several first balls in a ring shape into the inner groove of the base. The shim assembly mechanism 6 is used to assemble shims onto the top of the first balls. The spring assembly mechanism 7 is used to assemble springs and drive shafts sequentially into the interior of the base. The second ball assembly mechanism 8 is used to assemble a pair of second balls along the groove at the bottom of the base to the outer wall of the drive shaft. The gear assembly mechanism 9 is used to assemble three sets of gears onto the top of the drive shaft. The unloading mechanism 10 is used to automatically unload the assembled finished product. The first ball assembly mechanism 5 includes a first mounting frame 501. A first translation mechanism 504 is provided in the middle of the first mounting frame 501. A first lifting mechanism 506 is fixedly connected to the moving platform of the first translation mechanism 504. A movable plate 505 is fixedly connected to the lifting platform of the first lifting mechanism 506. A first ball pressing cylinder 507 is provided on the upper part of the side wall of the movable plate 505. The piston rod of the first ball pressing cylinder 507 is horizontally fixedly connected to a first... The lifting plate has several first ball bearing pressure rods 515 vertically fixedly connected to its top. The first ball bearing pressing cylinder 507 is horizontally fixed to one side of the turntable conveying mechanism 3 with a fixed plate 521. The top of the fixed plate 521 is vertically fixedly connected to three first ball bearing feeding pipes 514. The lower part of the side wall of the movable plate 505 is fixedly connected to an installation block 508. The inner side of the installation block 508 is slidably connected to a first ball bearing feeding push block 509. The top of the first ball bearing feeding push block 509 is provided with three sets of storage holes 517.The bottom ends of the first ball feed pipe 514 and the first ball pressure rod 515 extend through the mounting block 508 to the top of the first ball feed push block 509. The top of the first mounting frame 501 is fixedly connected to the first ball hopper 502. The bottom pipe of the first ball hopper 502 is connected to three first ball discharge pipes 503. The three first ball discharge pipes 503 are respectively connected to the corresponding first ball feed pipes 514. The bottom of the mounting block 508, away from the turntable conveyor mechanism 3, is horizontally provided with a first feeding cylinder 510. The piston rod of the first feeding cylinder 510 is connected to the first ball feed push block 509. The material pusher block 509 is fixedly connected. The mounting block 508 is horizontally fixedly connected to the side away from the movable plate 505 with a first material blocking cylinder 519. The piston rod of the first material blocking cylinder 519 is fixedly connected to a first material blocking plate 520. The other end of the first material blocking plate 520 extends through the side wall of the mounting block 508 to the bottom of the first ball bearing pusher block 509. The bottom of the mounting block 508 is vertically fixedly connected to three sets of first ball bearing mounting nozzles 518. The first ball bearing mounting nozzles 518 are located directly below the opposing first ball bearing pressure rods 515. A sensor 516 is provided on the top of the first ball bearing pressure rods 515. During assembly, the limiting mechanism 4 limits the base, spring, and drive shaft of the striking block respectively. Then, the turntable conveying mechanism 3 drives the limiting mechanism 4 to move to the bottom of the first ball assembly mechanism 5. The first ball assembly mechanism 5 assembles several first balls in a ring shape into the inner groove of the base. During assembly, the first translation mechanism 504 drives the first ball mounting nozzle 518 to move to the top of the base. Then, the first lifting mechanism 506 drives the first ball mounting nozzle 518 downward to abut against the base. At this time, the first balls inside the first ball hopper 502 flow into the first ball loading pipe 514 along the first ball unloading pipe 503, and then into the corresponding storage hole 517. By changing the diameter and height of the storage hole 517, the number and size of the first balls can be adjusted, so that first balls of different diameters can be installed. Then, the first loading cylinder 510 drives the first ball... The ball feeding pusher 509 moves to the assembly station and drives the first baffle plate 520 to move away from the first ball feeding pusher 509 via the first baffle cylinder 519. At this time, the storage hole 517 is connected to the first ball mounting nozzle 518 at the bottom. Then, the first ball assembly cylinder 507 drives the first ball pressure rod 515 to move downward to extend into the corresponding storage hole 517, generating a downward pushing force on the first ball inside the storage hole 517, so that the first ball flows out along the first ball mounting nozzle 518 to the inner groove of the base and is evenly arranged in a ring. When the first ball pressure rod 515 moves, the sensor 516 on its top can sense the pushing depth of the first ball pressure rod 515 to avoid the first ball being missed or mis-installed. After the first ball is assembled, the turntable conveying mechanism 3 drives the limiting mechanism 4 to move to the bottom of the gasket assembly mechanism 6, and the gasket assembly mechanism 6 assembles the gasket to the top of the first ball.Then, the limiting mechanism 4 moves to the bottom of the spring assembly mechanism 7, whereby the spring and drive shaft are sequentially assembled inside the base. Next, the limiting mechanism 4 moves to the bottom of the second ball assembly mechanism 8, whereby a pair of second balls are assembled along the groove at the bottom of the base to the outer wall of the drive shaft. Finally, the limiting mechanism 4 moves to the bottom of the gear assembly mechanism 9, whereby the gear assembly mechanism 9 assembles three sets of gears to the top of the drive shaft. After assembly, the limiting mechanism 4 moves to the bottom of the unloading mechanism 10, whereby the unloading mechanism 10 transports the assembled finished product into the material box 12, achieving automatic unloading of the finished product. Through the above steps, efficient automatic assembly of different components of the striking block can be achieved, effectively improving the assembly efficiency of the striking block and reducing production costs.

[0036] An oiling gun 512 is fixedly connected to the side of the movable plate 505 facing the turntable conveyor mechanism 3. An oiling nozzle 513 is located at the bottom of the oiling gun 512, and an oil inlet pipe 511 is vertically installed at the top of the oiling gun 512. After the first ball bearing is assembled, the first ball bearing mounting nozzle 518 is reset. The oiling nozzle 513 is driven to move to directly above the base via the first translation mechanism 504, and then driven downwards to abut against the base via the first lifting mechanism 506. Lubricating oil is injected into the base through the oiling gun 512, which lubricates the first ball bearing and subsequent components, reducing wear between parts.

[0037] Please see Figure 4 The limiting mechanism 4 includes a base plate 401, with a base limiting seat 402 vertically fixed to the upper center of the base plate 401. A spring limiting seat 403 and a drive shaft limiting seat 404 are respectively provided on both sides of the base limiting seat 402. During assembly, the base of the striking block is placed on top of the base limiting seat 402, and then the spring and drive shaft are placed on top of the spring limiting seat 403 and drive shaft limiting seat 404 respectively to limit their movement, facilitating subsequent assembly.

[0038] Please see Figure 9The gasket assembly mechanism 6 includes a second mounting frame 601. A second translation mechanism 602 is provided on the top of the second mounting frame 601. A second lifting mechanism 603 is fixedly connected to the moving platform of the second translation mechanism 602.

Several vibrating feeders 605 are respectively provided on both sides of the second mounting frame 601. A gasket pushing cylinder 606 is horizontally provided on the outer side of the discharge port of the vibrating feeder 605. During gasket assembly, the required size gasket is fed by the corresponding vibratory feeder 605. When the gasket moves to the discharge port of the vibratory feeder 605, the gasket pusher cylinder pushes the gasket to the assembly station. At this time, the second translation mechanism 602 drives the gasket suction nozzle 604 to move directly above the gasket. Then, the second lifting mechanism 603 drives the gasket suction nozzle 604 to move downward to pick up the gasket. Then, the second translation mechanism 602 drives the gasket suction nozzle 604 to move directly above the base. Then, the second lifting mechanism 603 drives the gasket suction nozzle 604 to move downward to install the gasket on the top of the first ball inside the base, thus realizing the automatic assembly of the gasket.

[0039] Please see Figure 10 The spring assembly mechanism 7 includes a third mounting bracket 701. A third translation mechanism 702 is provided on the top of the third mounting bracket 701. A third lifting mechanism 703 is fixedly connected to the moving platform of the third translation mechanism 702.

A pair of first grippers 705 are fixedly connected to the piston rod of the spring clamping cylinder 704, and a pair of second grippers 707 are fixedly connected to the piston rod of the drive shaft clamping cylinder 706. During spring assembly, the third translation mechanism 702 first drives the spring clamping cylinder 704 at the bottom of the third lifting mechanism 703 to move to the top of the spring. Then, the third lifting mechanism 703 drives the spring clamping cylinder 704 to move downward to the spring clamping position, where the first gripper 705 clamps the spring. At this time, the second gripper 707 opens to avoid interference with the base. Then, the third lifting mechanism 703 resets, causing the spring to disengage from the spring limiting seat 403. Then, the third translation mechanism 702 drives the spring clamping cylinder 704 to move to the top of the base, and the third lifting mechanism 703 drives the spring clamping cylinder 704 downward to install the spring inside the base. The above steps are repeated to install the drive shaft at the center of the base, so that the spring is sleeved on the outside of the drive shaft, thereby realizing the automatic assembly of the spring and the drive shaft.

The side wall of the fourth mounting bracket 801 is fixedly connected to a second ball assembly cylinder 808. The piston rod of the second ball assembly cylinder 808 is horizontally fixedly connected to a second lifting plate. The top of the second lifting plate is vertically fixedly connected to a pair of second ball discharge pipes 809, which are respectively connected to the bottom pipes of the pair of second ball loading pipes. During the second ball assembly, the fourth lifting mechanism 802 drives the pressure head 803 downward, generating downward pressure on the drive shaft until the bottom end of the drive shaft extends to the lower side of the base and stops at the second ball assembly station. Then, the second ball assembly cylinder 808 drives the second ball discharge pipe 809 upward to the second ball assembly station. At this time, a pair of second balls in the second ball hopper 804 flow into the second ball loading block along a pair of second ball discharge pipes 805. Then, the second baffle cylinder 807 drives the second baffle plate to detach from the second ball loading block. The pair of second balls fall into the bottom second ball feed tube. At this time, high-pressure gas is introduced into the second ball feed tube through the high-pressure connector 806 at the top of the second ball feed tube, pushing the pair of second balls into the second ball discharge tube 809. They flow out along the second ball discharge tube 809 and then enter the pair of second ball mounting slots on the side wall of the drive shaft along a pair of grooves at the bottom of the base. Then the pressure head 803 is reset, and the drive shaft is reset under the elastic force of the spring, causing the second balls to move upward with the drive shaft to the inside of the base, realizing the automatic assembly of the second balls.

During gear assembly, the fifth translation mechanism 902 drives the gear suction nozzle 906 to move to the top of the discharge port of the gear feeder 903. Then, the fifth lifting mechanism 904 drives the gear suction nozzle 906 downward to pick up the gear. The first rotation mechanism 905 then drives the empty gear suction nozzle 906 to rotate to the top of the gear. This process is repeated to sequentially feed the three sets of gear suction nozzles 906. Then, the fifth translation mechanism 902 drives the first rotation mechanism 905 to move directly above the base, ensuring it is coaxial with the drive shaft. At this time, the fifth lifting mechanism 904 drives the three sets of gear suction nozzles 906... 06 moves downwards to the gear assembly station, so that the gear and the arc-shaped pressure block 917 are in a horizontal state. Then, the sixth translation mechanism 914 drives the top sliding plate 915 to move to the gear assembly station, so that the pair of second gear pressing cylinders 916 and the first gear pressing cylinder 913 on both sides of its bottom are evenly arranged around the axis of the transmission shaft. At this time, the pair of second gear pressing cylinders 916 and the first gear pressing cylinder 913 drive the three sets of arc-shaped pressure blocks 917 to move synchronously towards the axis of the transmission shaft, and synchronously press the gears at the bottom of the three sets of gear suction nozzles 906 into the gear mounting grooves at the top of the transmission shaft.

[0042] The top of the lifting platform of the sixth lifting mechanism 907 is fixedly connected to a gear pin pressing cylinder 908. The piston rod of the gear pin pressing cylinder 908 is fixedly connected to three gear pin pressing rods 910. The bottom of the lifting platform of the sixth lifting mechanism 907 is fixedly connected to a gear pin assembly pressing block. The top of the gear pin assembly pressing block is vertically fixedly connected to three sets of gear pin feeding pipes 909. The middle of the gear pin assembly pressing block is slidably connected to a gear pin feeding push block. The side wall of the gear pin assembly pressing block is horizontally fixedly connected to a gear pin feeding cylinder 911. The piston rod of the gear pin feeding cylinder 911 is fixedly connected to the gear pin feeding push block. After the gear is pressed into place, the fifth translation mechanism 902 drives the fifth lifting mechanism 904 to detach from the base, and at the same time drives the sixth lifting mechanism 907 to move to the top of the base. At this time, the gear pin flows into the gear pin feeding push block in the middle of the gear pin assembly pressing block through the gear pin feeding pipe 909. The gear pin feeding cylinder 911 drives the gear pin feeding push block to move to directly below the gear pin pressing rod 910. Then, the gear pin pressing cylinder 908 drives the bottom gear pin pressing rod 910 to press the gear pin in the gear pin feeding push block into the corresponding gear center hole until the bottom end of the gear pin is rotatably connected to the drive shaft, thereby realizing the automatic assembly of the gear.

[0043] Please see Figure 13 The unloading mechanism 10 includes a seventh mounting frame 1001. A seventh translation mechanism 1002 is provided on the top of the seventh mounting frame 1001. A seventh lifting mechanism 1003 is fixedly connected to the moving platform of the seventh translation mechanism 1002. A second rotating mechanism 1004 is fixedly connected to the lifting platform of the seventh lifting mechanism 1003. A rotating plate 1005 is fixedly connected to the rotating platform of the second rotating mechanism 1004. A finished product clamping cylinder 1006 is vertically fixedly connected to the lower side of the other end of the rotating plate 1005. A pair of third grippers 1007 are fixedly connected to the piston rod of the finished product clamping cylinder 1006. A plurality of support seats 11 are provided on the lower side of the seventh translation mechanism 1002. A material box 12 is detachably provided on the top of the plurality of support seats 11. After assembly, the seventh translation mechanism 1002 and the second rotation mechanism 1004 drive the finished product clamping cylinder 1006 to move directly above the finished product. Then, the seventh lifting mechanism 1003 drives the finished product clamping cylinder 1006 to move downward, and the finished product is clamped by the third gripper 1007. Then, the above steps are repeated in reverse to place the finished product into the material box 12, thereby realizing automatic unloading of the finished product.

[0044] Working principle: During assembly, the limiting mechanism 4 limits the base, spring, and drive shaft of the striking block respectively. Then, the turntable conveying mechanism 3 drives the limiting mechanism 4 to move to the bottom of the first ball assembly mechanism 5. The first ball assembly mechanism 5 assembles several first balls in a ring shape into the inner groove of the base. During assembly, the first translation mechanism 504 drives the first ball mounting nozzle 518 to move to the top of the base. Then, the first lifting mechanism 506 drives the first ball mounting nozzle 518 to move downward until it abuts against the base. At this time, the first balls inside the first ball hopper 502 flow into the first ball loading pipe 514 along the first ball unloading pipe 503, and then flow into the corresponding storage hole 517. Internally, by changing the diameter and height of the storage hole 517, the number and size of the first ball bearings can be adjusted, thus allowing the installation of first ball bearings of different diameters. Then, the first feeding cylinder 510 drives the first ball bearing feeding pusher 509 to move to the assembly station, and the first baffle cylinder 519 drives the first baffle plate 520 to move until it disengages from the first ball bearing feeding pusher 509. At this time, the storage hole 517 is connected to the first ball bearing mounting nozzle 518 at the bottom. Then, the first ball bearing assembly cylinder 507 drives the first ball bearing pressure rod 515 to move downward to extend into the corresponding storage hole 517, generating a downward pushing force on the first ball bearing inside the storage hole 517, causing the first ball bearing to move along the first... The ball bearing installation nozzle 518 flows out into the inner groove of the base and is evenly arranged in a ring. When the first ball bearing pressure rod 515 moves, the sensor 516 on its top can sense the pushing depth of the first ball bearing pressure rod 515 to avoid the first ball bearing being missed or misinstalled. Then, the first ball bearing installation nozzle 518 is reset, and the first translation mechanism 504 drives the oil injection nozzle 513 to move to the top of the base. Then, the first lifting mechanism 506 drives the oil injection nozzle 513 to move downward to abut against the base, and the oil injection gun 512 injects lubricating oil into the base. After the first ball bearing is assembled, the turntable conveying mechanism 3 drives the limiting mechanism 4 to move to the bottom of the gasket assembly mechanism 6, and the gasket assembly mechanism 6 then... The gasket is assembled to the top of the first ball bearing; then the limiting mechanism 4 moves to the bottom of the spring assembly mechanism 7, and the spring and the drive shaft are assembled into the interior of the base in sequence through the spring assembly mechanism 7; then the limiting mechanism 4 moves to the bottom of the second ball bearing assembly mechanism 8, and a pair of second balls are assembled into the outer wall of the drive shaft along the groove at the bottom of the base through the second ball bearing assembly mechanism 8; finally, the limiting mechanism 4 moves to the bottom of the gear assembly mechanism 9, and three sets of gears are assembled into the top of the drive shaft through the gear assembly mechanism 9; after assembly, the limiting mechanism 4 moves to the bottom of the unloading mechanism 10, and the unloading mechanism 10 transports the assembled finished product into the material box 12, realizing automatic unloading of the finished product.
