Description

Technical Field

[0001] This utility model relates to the field of bolt installation and fixing technology, specifically a bolt installation and fixing device. Background Technology

[0002] A bolt installation and fixing device refers to a tool or equipment used to accurately and quickly install bolts in a specific position and maintain a secure connection.

[0003] Working principle:

[0004] Bolt clamping and positioning: Using clamps, bolts of various specifications can be clamped to meet different working conditions and stably hold the bolts. Through structures such as guide grooves, the bolt is accurately guided to the position to be installed when installing nuts, and precisely aligned with the threaded hole on the nut to ensure accurate positioning during installation.

[0005] Auxiliary positioning: By adjusting the positioning sleeve, the device is made perpendicular to the working surface, which increases the accuracy of the position during installation.

[0006] Impact block locking: Impact electric wrenches are usually characterized by unstable torque and excessive torque, which can easily damage bolts and workpieces. By locking the impact block through the slider controlled by the spring, it is prevented from moving backward with the contraction of the torsion spring, changing the impact type to a direct torque type. This makes it easier to control the maximum torque and apply the preload required for bolt installation, thus preventing damage to the bolt.

[0007] Existing bolt mounting and fixing devices have the following drawbacks: the existing devices have limited compatibility with bolt specifications, making it difficult to adapt to bolts of different diameters or special head shapes, and they cannot guide accurately, leading to bolt damage and losses.

[0018] Preferably, the PLC controller controls the battery to supply power to the first servo motor and the second servo motor.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. In this utility model, when installing bolts, the fixed sleeve is moved to make the device perpendicular to the working surface. The nut is aligned and placed into the hexagonal through hole, and is located in the middle of the first slider. The first servo motor is started, and the first servo motor drives the first fixed plate to move. The first fixed plate pushes the slide rod to move, and the slide rod drives the first slider to clamp the nut. At this time, the screw is located in the center of the hexagonal through hole and perpendicular to the working surface. When installing the nut, the top of the screw abuts against the positioning block. The above steps are repeated to fix it. If the device is not perpendicular to the working surface, the screw cannot move along the second sleeve, which facilitates the correct installation of the screw and nut. Through the clamping component, the problem of limited compatibility of existing devices with bolt specifications, difficulty in adapting to bolts of different specifications, inability to guide accurately, and resulting bolt damage and loss is solved.

[0021] 2. In this utility model, a second servo motor drives a first gear to rotate, which in turn drives a second gear to rotate. The second gear meshes with a planetary gear, causing a gear sleeve to rotate. First washers are detachably mounted on both sides of the gear sleeve. A fixing rod is fixedly mounted at the end of the gear sleeve, and a striking block is inserted into the end of the fixing rod. A torsion spring is detachably mounted between the striking block and the first washers. A transmission block is attached to the end of the striking block, and a transmission rod is detachably mounted at the end of the transmission block. A second washer is detachably mounted on the side of the transmission block. When the transmission rod is subjected to a large torque, it compresses the torsion spring, causing the striking block to separate from the transmission block. After separation, the torsion spring returns to its original position, and the striking block instantly strikes the transmission block, generating a large torque that drives the transmission rod to rotate. The fixing sleeve then compresses the second slider, causing the spring to compress and insert the bottom of the second slider between the striking block and the first washers. The second slider, striking block, and first washers are all slidably connected, preventing the striking block from separating from the transmission block, allowing it to directly transmit torque. By adjusting the components, the problem of the striking device being unsuitable for bolt installation and prone to bolt damage is solved. Attached Figure Description

A third fixing plate 49 is fixedly mounted on the bottom of the first sleeve 3. A square through hole 416 is provided in the center of the third fixing plate 49. A second fixing plate 410 is fixedly mounted between the first fixing plate 46 and the third fixing plate 49. A first servo motor 41 is detachably mounted in the middle of the second fixing plate 410. 1. A servo motor is a motor used for precise control of position, speed, and torque. It is often used as an actuator to convert input voltage signals into angular displacement or angular velocity output on the shaft. When the first servo motor 411 is off, its electromagnetic brake locks the motor output shaft. A lead screw 48 is detachably mounted on the end of the first servo motor 411, and the first fixing plate 46 is threadedly connected to the lead screw 48. Driving the first servo motor 411 causes the lead screw 48 to rotate, and the lead screw 48 causes the first fixing plate 46 to move. A positioning element is provided in the hexagonal through hole 43. The positioning element includes a component detachably mounted in the hexagonal through hole 43. The second sleeve 412 has a fixing plate 413 rotatably connected to its bottom. A spring 414 is detachably installed on the fixing plate 413. A positioning block 415 is detachably installed at the end of the spring 414 and is inserted into the second sleeve 412. The positioning block 415 is slidably connected to the second sleeve 412. A tapered groove adapted to the chamfer of the top of the stud is opened on the left side of the positioning block 415. When tightening the stud and nut, the stud is used to push against the groove on the positioning block 415. The positioning block 415 can only move inside the second sleeve 412 when aligned, which is used to assist in alignment.

[0034] The main body 1 is equipped with an adjustment component 5 to adapt to different working requirements;

[0035] A second servo motor 51 is detachably installed inside the main body 1. A first gear 52 is detachably installed at the end of the second servo motor 51. A second gear 53 is meshed with the side of the first gear 52. Three second gears 53 are arranged in a circumferential array around the output shaft of the second servo motor 51. A gear sleeve 54 is fitted around the second gear 53, and a planetary gear 55 is fitted around the gear sleeve 54. The planetary gear 55 meshes with the second gear 53 and is detachably installed on the inner wall of the main body 1. The second servo motor 51 drives the first gear 52 to rotate, and the first gear 52 drives the second gear 53 to rotate. The second gear 53 meshes with the planetary gear 53. 5. Engagement drives the gear sleeve 54 to rotate. First washers 56 are detachably mounted on both sides of the gear sleeve 54. A fixing rod 57 is fixedly mounted at the end of the gear sleeve 54. A striking block 58 is inserted into the end of the fixing rod 57. A torsion spring 59 is detachably mounted between the striking block 58 and the first washers 56. A transmission block 510 is attached to the end of the striking block 58. A transmission rod 511 is detachably mounted at the end of the transmission block 510. A second washer 512 is detachably mounted on the side of the transmission block 510. When the transmission rod 511 is subjected to a large torque, it compresses the torsion spring 59. The torsion spring 59 contracts, causing the striking block 58 to separate from the transmission block 510. After separation, the torsion spring 59 returns to its original position, and the striking block 58 instantly strikes the transmission block 510. A large torque is generated, driving the transmission rod 511 to rotate. The adjusting component 5 includes a through groove 513 on the main body 1. A second slider 514 is slidably connected in the through groove 513. The second slider 514 is located between the striking block 58 and the first washer 56, and is located above the torsion spring 59. A spring piece 515 is detachably installed in the through groove 513 and is inserted into the second slider 514. When the second slider 514 is pressed, the spring piece 515 is compressed, causing the bottom of the second slider 514 to insert between the striking block 58 and the first washer 56. The second slider 514 is slidably connected to both the striking block 58 and the first washer 56, preventing the striking block 58 from contacting the transmission block 510. The main body 1 is separated, and a fixing sleeve 516 is provided on the outer sleeve. A first limiting ring 517 is detachably installed on the fixing sleeve 516 to limit the fixing sleeve 516. A second limiting ring 518 is detachably installed on the fixing sleeve 516, and the second limiting ring 518 is located to the side of the first limiting ring 517 to limit the fixing sleeve 516. A limiting block 519 is fixedly installed on the main body 1, and the limiting block 519 is located between the first limiting ring 517 and the second limiting ring 518. The PLC controller 8 controls the battery 6 to supply power to the first servo motor 411 and the second servo motor 51. It is used to control the maximum torque, speed and direction of the first servo motor 411 and the second servo motor 51.

[0036] Working principle:

[0037] During use, when installing the bolt, move the fixing sleeve 516 to make the device perpendicular to the working surface, align the nut with the hexagonal through hole 43, and position it in the middle of the first slider 42. Start the first servo motor 411, which drives the first fixing plate 46 to move. The first fixing plate 46 pushes the slide rod 45 to move, and the slide rod 45 drives the first slider 42 to clamp the nut. At this time, the screw is located at the center of the hexagonal through hole 43 and perpendicular to the working surface. Drive the second servo motor 51, which drives the first sleeve 3 to rotate and tighten the bolt. When installing the nut, make the top of the screw press against the ground. The conical groove inside the positioning block 415 is used to fix the nut according to the previous steps. If the device is not perpendicular to the working surface, the screw cannot move along the second sleeve 412. When the device is perpendicular to the working surface, the second servo motor 51 is driven. The second servo motor 51 drives the first sleeve 3 to rotate and tighten the nut. At this time, the positioning block 415 moves along the second sleeve 412, which facilitates the correct installation of the screw and nut. Through the clamping component 4, the problem of limited compatibility of existing devices with bolt specifications, difficulty in adapting to bolts of different specifications, inability to guide accurately, and bolt damage and loss are solved.

[0038] When the second servo motor 51 drives the impact-type device to operate, the second servo motor 51 drives the first gear 52 to rotate, the first gear 52 drives the second gear 53 to rotate, the second gear 53 meshes with the planetary gear 55, driving the gear sleeve 54 to rotate. First washers 56 are detachably installed on both sides of the gear sleeve 54. A fixing rod 57 is fixedly installed at the end of the gear sleeve 54. An impact block 58 is inserted into the end of the fixing rod 57. A torsion spring 59 is detachably installed between the impact block 58 and the first washers 56. A transmission block 510 is attached to the end of the impact block 58. A transmission rod 511 is detachably installed at the end of the transmission block 510. A second washer 512 is detachably installed on the side of the transmission block 510. When the transmission rod 511 is subjected to a large torque, it will... The compression of the torsion spring 59 causes the striking block 58 to separate from the transmission block 510. After separation, the torsion spring 59 returns to its original position. The striking block 58 strikes the transmission block 510 instantaneously, generating a large torque that drives the transmission rod 511 to rotate. When the moving fixed sleeve 516 is moved, it presses against the second slider 514, and the spring 515 is compressed, causing the bottom of the second slider 514 to insert between the striking block 58 and the first washer 56. The second slider 514 is slidably connected to the striking block 58 and the first washer 56, preventing the striking block 58 from separating from the transmission block 510. This changes the striking type to a direct torque type, allowing it to directly transmit torque and making it easier to control the torque magnitude. By adjusting component 5, the problem that the striking type device is not suitable for bolt installation and is prone to bolt damage is solved.
