Description

Technical Field

[0001] This application relates to the technical field of eccentric bolt manufacturing, and in particular to a manufacturing equipment and process for eccentric bolts. Background Technology

[0002] Currently, eccentric bolts are characterized by a pre-set eccentricity between the bolt axis and the rotation center of the head (or fastening part). Utilizing this geometric characteristic, the eccentric bolt can convert rotational motion into minute radial displacement during screwing, thereby achieving continuous fine-tuning of the connected parts' position, gap compensation, and precise alignment without damaging the connecting components. This design not only greatly simplifies the assembly process and improves the tolerance for errors but also effectively enhances the connection accuracy and operational stability of mechanical structures, thus becoming an indispensable key foundation in modern precision manufacturing and assembly technology.

[0003] Generally, a center hole needs to be opened at the end of the eccentric bolt. The center hole of the eccentric bolt is the only unified benchmark for the machining, inspection and assembly of eccentric parts.

[0004] Existing eccentric bolt production equipment generally includes a frame, a clamping device mounted on the top of the frame for clamping the bolt body, a drilling bracket slidably mounted on the top of the frame, a drilling support slidably connected to the drilling bracket, a vertical drive mechanism mounted on the drilling bracket for driving the drilling support to move, a drilling motor mounted on the drilling support, a drill bit mounted on the output shaft of the drilling motor, and a lateral drive mechanism mounted on the top of the frame for driving the drilling bracket to move laterally.

[0005] However, the aforementioned equipment is inconvenient for collecting the drilled bolt bodies, which can easily affect production efficiency. Summary of the Invention

[0006] To facilitate the collection of drilled bolt bodies, this application provides a production equipment for eccentric bolts, employing the following technical solution: An eccentric bolt production device includes a frame, a clamping device mounted on the top of the frame for clamping the bolt body, a drilling bracket slidably mounted on the top of the frame, a drilling support slidably connected to the drilling bracket vertically, a vertical drive mechanism mounted on the drilling bracket for driving the drilling support to move, a drilling motor mounted on the drilling support, a drill bit mounted on the output shaft of the drilling motor, and a horizontal drive mechanism mounted on the top of the frame for driving the drilling bracket to move laterally. The frame includes a base, on which a receiving device is mounted. The receiving device includes a receiving electric push rod mounted on the top of the base, a movable frame mounted on the output end of the receiving electric push rod, and a receiving bucket bolted to the top of the movable frame. A discharge through hole is provided on the top of the frame corresponding to the receiving bucket.

[0007] By adopting the above technical solution, when drilling is required on the bolt body, the bolt body is first clamped by the clamping device. Then, the drilling motor is started, and the output shaft of the drilling motor drives the drill bit to rotate. Then, the vertical drive mechanism drives the drilling support to move downward, which in turn drives the drill bit to move downward, thus drilling the bolt body. Then, the vertical drive mechanism drives the drilling support to reset, which in turn drives the drill bit to reset. Finally, the bolt body is released by the clamping device, and the bolt body is discharged into the receiving bucket through the discharge hole, thus enabling the collection of the drilled bolt body. In summary, the set receiving device facilitates the collection of the drilled bolt body.

[0009] By adopting the above technical solution, when it is necessary to clamp and fix the bolt body, the clamping electric push rod is activated first. At this time, the output end of the clamping electric push rod drives the movable clamping plate to move towards the fixed clamping plate, so that the bolt body can be clamped and fixed. In summary, the clamping device is designed to facilitate the clamping and fixing of the bolt body.

[0010] Optionally, the sidewall of the discharge through hole is provided with an operating groove, and a support device for supporting the bolt body is installed in the operating groove. The support device includes a rotating shaft rotatably connected to the sidewall of the operating groove, a separation electric push rod fixed to one end of the rotating shaft, a support cylinder fixed to the output end of the separation electric push rod, and a drive mechanism installed on the sidewall of the operating groove for driving the rotating shaft to rotate; the bottom of the bolt body is inserted into the inner cavity of the support cylinder.

The output end of the clamping electric push rod drives the movable clamping plate to loosen the bolt body. Next, the separating electric push rod is activated. The output end of the separating electric push rod drives the support cylinder to move away from the fixed clamping plate. Then, the driving electric push rod is activated. The output end of the driving electric push rod drives the rack to move upward. The upward movement of the rack drives the spur gear to rotate. The rotation of the spur gear drives the rotating shaft to rotate. The rotation of the rotating shaft drives the support cylinder to rotate downward. The downward rotation of the support cylinder can pour the bolt body into the receiving bucket, thus facilitating the further collection of the drilled bolt body. In addition, the support cylinder makes it easy for operators to loosen the bolt body when it needs to be clamped and fixed, thereby reducing safety risks.

The buffer device includes a strip-shaped hole in the side wall of the receiving hopper, a buffer guide rod bolted to the inner wall of the strip-shaped hole, a sliding sleeve slidably connected to the buffer guide rod, and a buffer elastic plate bolted to one end of the sliding sleeve. A movable plate is installed on the side wall of the rack, and a pull rod is bolted to the bottom of the movable plate. The end of the sliding sleeve away from the buffer elastic plate abuts against the side wall of the pull rod, and the buffer elastic plate is inclined.

[0014] By adopting the above technical solution, the rack moves upward, which drives the tie rod to move upward, the tie rod moves upward, which drives the sliding sleeve to move upward, and the sliding sleeve moves upward, which drives the buffer elastic plate to move upward, thus facilitating the buffering of the bolt body.

[0015] Optionally, the lateral drive mechanism includes a lateral support mounted on the top of the frame, a lateral drive motor mounted on one end of the lateral support, a lateral lead screw mounted on the output shaft of the lateral drive motor, and a lateral guide rod mounted on the lateral support; the drilling support is threadedly connected to the lateral lead screw, and the drilling support is slidably connected to the lateral guide rod; the lateral drive mechanism is used to finely adjust the lateral position of the drilling support so that the drill bit is aligned with the center of the bolt body cap.

[0016] By adopting the above technical solution, when it is necessary to make lateral fine adjustments to the position of the drill bit, the lateral drive motor is started first. At this time, the output shaft of the lateral drive motor drives the lateral lead screw to rotate. The rotation of the lateral lead screw drives the drilling support to move slightly laterally. The slight lateral movement of the drilling support can make lateral fine adjustments to the position of the drill bit. In summary, the lateral drive mechanism facilitates lateral fine adjustments to the position of the drill bit.

[0017] Optionally, the vertical drive mechanism includes a vertical drive motor mounted on the top of the drilling support, a vertical lead screw mounted on the output shaft of the vertical drive motor, and a vertical guide rod fixed to the side wall of the drilling support; the drilling support is threaded to the vertical lead screw, and the drilling support is slidably connected to the vertical guide rod.

The two ends of the spring abut against the opposite inner sides of the sealing tube and the support frame, respectively. A limit ring is threaded to the end of the second moving rod away from the sealing tube.

[0020] By adopting the above technical solution, the drilling support reset drive first moving rod moves upward, first moving rod moves upward and drives piston plate to move upward. After piston plate moves upward a certain distance, sealing plate separates from sealing pipe under air pressure. Then, under the action of air supply pipe, strong airflow is generated in air blowing pipe, which can blow away debris near bolt body. In summary, the debris blowing device is set to facilitate the cleaning of debris near bolt body.

In addition, the upward movement of the rack drives the drive rod to move upward, and then the drive rod drives the vertical tube to rotate under the action of the spiral block and spiral groove. The rotation of the vertical tube drives the first bevel gear to rotate, the rotation of the first bevel gear drives the second bevel gear to rotate, the rotation of the second bevel gear drives the horizontal shaft to rotate, and the rotation of the horizontal shaft drives the chip suction hood to rotate.

[0023] This application provides a manufacturing process for eccentric bolts, employing the following technical solution: A manufacturing process for an eccentric bolt includes the following steps: When drilling is required on a bolt, first place the bolt inside the support cylinder, then activate the clamping electric actuator. The output end of the actuator drives the movable clamping plate to hold the bolt. Next, activate the vertical drive motor and the drilling motor. The output shaft of the vertical drive motor drives the vertical lead screw to rotate, and the output shaft of the drilling motor drives the drill bit to rotate. The rotation of the vertical lead screw drives the drilling support to move downwards, which in turn moves the drill bit downwards, allowing drilling to begin. Then, activate the vertical drive motor again. The output shaft drives the vertical lead screw to rotate in the opposite direction. This reverse rotation of the vertical lead screw drives the drilling support to reset, which in turn resets the drill bit. After drilling the bolt body, the clamping electric push rod is activated. Its output end then drives the movable clamping plate to release the bolt body. Next, the disengagement electric push rod is activated. Its output end drives the support cylinder to move away from the fixed clamping plate. Then, the drive electric push rod is activated. Its output end drives the rack to move upwards, which in turn drives the spur gear to rotate. The rotation of the spur gear drives the rotary... The rotating shaft drives the support cylinder to rotate downwards, which in turn pours the bolts into the receiving hopper, facilitating the collection of drilled bolts. Furthermore, the upward movement of the rack drives the pull rod upwards, which in turn drives the sliding sleeve upwards, which in turn drives the buffer plate upwards, thus cushioning the bolts. Finally, the resetting of the drilling support drives the first moving rod upwards, which in turn drives the piston plate upwards. After the piston plate moves upwards a certain distance, it is sealed under air pressure. The sealing plate separates from the sealing tube, and then a strong airflow is generated in the air blowing pipe under the action of the air supply pipe, which can blow away the debris near the bolt body. At this time, the debris suction hood is set up to facilitate the collection of debris. In addition, the rack moves upward, driving the drive rod to move upward.

[0044] This application discloses a manufacturing process for eccentric bolts, including the following steps: When drilling is required on bolt body 1, first place bolt body 1 inside support cylinder 63, then start clamping electric push rod 52. At this time, the output end of clamping electric push rod 52 drives movable clamping plate 53 to clamp bolt body 1. Next, start vertical drive motor 31 and drilling motor 23. Then, the output shaft of vertical drive motor 31 drives vertical lead screw 32 to rotate and the output shaft of drilling motor 23 drives drill bit 24 to rotate. The rotation of vertical lead screw 32 drives drilling support 22 to move downward. The downward movement of drilling support 22 drives drill bit 24 to move downward, and at this time, bolt body 1 can be drilled. Then start vertical drive motor 31. At this time, the output shaft of vertical drive motor 31... The vertical lead screw 32 is driven to rotate in the opposite direction, which drives the drilling support 22 to reset, and the reset of the drilling support 22 drives the drill bit 24 to reset. After drilling the bolt body 1, the clamping electric push rod 52 is activated, and then the output end of the clamping electric push rod 52 drives the movable clamping plate 53 to loosen the bolt body 1. Next, the disengagement electric push rod 62 is activated, and then the output end of the disengagement electric push rod 62 drives the support cylinder 63 to move away from the fixed clamping plate 51. Then, the drive electric push rod 64 is activated, and then the output end of the drive electric push rod 64 drives the rack 65 to move upward. The upward movement of the rack 65 drives the spur gear 66 to rotate, and the rotation of the spur gear 66 drives the rotating shaft 61 to rotate. The rotating shaft 61 rotates, causing the support cylinder 63 to rotate downwards. This downward rotation of the support cylinder 63 pours the bolt body 1 into the receiving bucket 43, facilitating the collection of the drilled bolt body 1. Furthermore, the rack 65 moves upwards, causing the pull rod 76 to move upwards. The pull rod 76 then drives the sliding sleeve 73 to move upwards, which in turn drives the buffer elastic plate 74 to move upwards, thus buffering the bolt body 1. Additionally, the drilling support 22 resets, driving the first moving rod 84 to move upwards. The first moving rod 84 then drives the piston plate 841 to move upwards. After the piston plate 841 moves upwards a certain distance, under the action of air pressure, the sealing plate 87 and the sealing tube... Separating from the bolt body 1, the air supply pipe 81 generates a strong airflow in the air blowing pipe 83, which blows away the debris near the bolt body 1. At this time, the debris suction hood 92 facilitates the collection of debris. In addition, the rack 65 moves upward, driving the drive rod 98 to move upward. Then, the drive rod 98 drives the vertical pipe 95 to rotate under the action of the spiral block 981 and the spiral groove 951. The rotation of the vertical pipe 95 drives the first bevel gear 96 to rotate. The rotation of the first bevel gear 96 drives the second bevel gear 97 to rotate. The rotation of the second bevel gear 97 drives the horizontal shaft 911 to rotate. The rotation of the horizontal shaft 911 drives the debris suction hood 92 to rotate. The rotation of the debris suction hood 92 facilitates the pouring of debris into the collection frame 99.
