Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of building construction, and in particular relates to a bolt assembly device for building panels. Background Art
[0002] In the field of building panel installation, bolt assembly typically relies on power wrenches or hand tools. Currently, operators rely on experience to determine the proper tightening. Even when connecting a large number of building panels, workers may relax their tightening requirements for some bolts, resulting in incomplete nuts and uneven exposed bolt shank lengths, affecting both aesthetics and the strength of the panel connection. To address this issue, a building panel bolt assembly device is provided that can standardize the exposed shank length. Summary of the Invention
[0003] The object of the present invention is to provide a bolt assembly device for building panels.
[0004] The present invention is achieved through the following measures: a bolt assembly device for building panels, characterized in that it includes an outer ring body, a bearing is concentrically arranged on the inner upper end of the outer ring body, the outer ring of the bearing is fixed on the outer ring body, and the inner ring is provided with a sleeve through a threaded connection, the pitch of the threaded connection is the same as the pitch of the bolt for building panels, the bottom of the sleeve is sealed and the sealing end is concentrically provided with a hexagonal groove matching the nut of the bolt for building panels, and a through hole is concentrically opened in the hexagonal groove to allow the rod of the bolt for building panels to pass through; the inner wall of the inner ring of the bearing is provided with an internal thread, and the outer wall of the sleeve is provided with an internal thread.
[0005] At least two horizontal rods are evenly distributed on the inner wall of the sleeve in the circumferential direction, and the inner ends of the horizontal rods are fixed with columns, and the columns are provided with blind holes for insertion; The nut also includes a motor, with a turntable fixed to the lower end of the motor's drive shaft. A connecting plate is removably attached to the lower end of the turntable. A plug rod is fixed below the connecting plate, corresponding to the blind socket. The column is provided with a locking mechanism for the plug rod. The connecting plate and turntable are typically connected by several bolts. A sleeve design with matching bearings and thread pitch allows precise synchronization of nut rotation and linear rise of the bolt shaft. The rising bolt shaft triggers the release of the locking mechanism, allowing disengagement only when the bolt is tightened to the set length.
[0006] The insertion rod is inserted into the blind plug-in port, the locking structure is locked and fixed, the hexagonal groove is aligned with the nut, and the rod is aligned with the through hole; the rotation of the drive shaft drives the sleeve to rotate, and the sleeve drives the nut to rotate and move down along the rod, and the upper end of the rod gradually approaches the locking structure and can realize the release of the locking structure through the contact between the rod and the locking structure. After the locking structure is released, the sleeve insertion rod can be separated from the blind plug-in port.
[0007] Furthermore, a slideway communicating with the blind insertion opening is opened at the lower portion of the outer wall of the column, and the locking structure includes a locking rod slidably arranged in the slideway, the inner end of the locking rod is inserted into the slideway from the outside of the column, and the outer end of the locking rod is arranged on the column via a spring, the spring is not subject to external force, the inner end of the locking rod extends into the blind insertion opening, and the extending end is provided with a trigger slope 1, and the lower end of the trigger slope 1 faces the axis of the sleeve; A slot is provided on the outer side of the lower portion of the insertion rod to cooperate with the locking rod. The insertion rod is inserted into the blind insertion opening and presses the trigger slope 1. The locking rod moves outward until the inner end of the locking rod is out of the blind insertion opening. When the slot on the insertion rod is aligned with the slide, the inner end of the locking rod is engaged with the slot to lock and fix the insertion rod. The outer end of the locking rod is symmetrically provided with conductive rods located on both sides of the column through an external connecting plate. The inner ends of the conductive rods face the center of the sleeve and are connected by a connecting rod. The inner end of the connecting rod is fixedly provided with a trigger block. The lower end of the trigger block is provided with a second trigger slope. The upper end of the second trigger slope is close to the center of the sleeve. When the rod of the bolt contacts the second trigger slope, the rod moves upward, driving the trigger block and the locking rod to move outward until the inner end of the locking rod is released from the slot, allowing the insertion rod to be released from the blind insertion hole. The blind insertion hole is generally rectangular.
[0008] The inclined trigger and spring locking structure realize mechanical self-control of the insertion rod, which is "locked when inserted and released when lifted", without the risk of electronic component failure.
[0009] Furthermore, the inclination angle of the trigger slope 1 and the trigger slope 2 is greater than 45 degrees and less than 80 degrees, preferably 60 degrees. The angle of the slope is greater than 45 degrees, which facilitates driving through the slope.
[0010] Furthermore, there are three horizontal rods, which are evenly distributed around the circumference to provide 120° symmetrical support, so that the sleeve is evenly stressed.
[0011] Furthermore, the outer ring body includes an upper ring and a lower ring arranged concentrically, and the lower end surface of the upper ring and the upper end surface of the lower ring are connected by a plurality of support rods. The split outer ring body (upper ring / lower ring + support rods) reduces weight.
[0012] Furthermore, the motor is provided with a housing including a handheld handle. The specific shape of the housing can be inspired by the housing of a handheld power tool. The motor housing is integrated with the handheld handle, which is ergonomic and improves operational stability.
[0013] How to use: Screw the sleeve (with a hexagonal groove at the bottom) into the inner ring of the bearing, ensuring that the thread pitch matches the bolt; insert the rod into the blind insertion hole on the column, and the locking rod of the locking structure is locked in the slot of the rod to fix it; vertically insert the bolt into the device to ensure that the rod passes through the through hole and the hexagonal groove engages the nut; start the motor, the motor drives the drive shaft and the turntable to rotate, the turntable drives the rod under the connecting disk to rotate, the sleeve rotates the nut synchronously, the nut and the sleeve move downward, and the rod of the bolt moves upward along the thread; when the rod of the bolt moves up to the set height, the rod contacts the second trigger slope of the trigger block, pushing the conduction rod outward, and the locking rod disengages from the slot on the rod; The rod can be removed from the blind insertion hole, and the component below the rod can be moved out of the sleeve as a whole, thus completing the assembly of a bolt and ensuring the extension length of the bolt rod. In addition, when using, it is best to keep the outer ring fixed, which is generally achieved by manual foot operation.
[0014] The beneficial effects of the technical solution provided by the embodiment of the present invention are: through a sleeve with the same pitch as the bolt connection, the sleeve moves with the nut, thereby realizing the relative upward movement of the bolt rod, and using the physical displacement of the rod as a control signal, the automatic disengagement of the driving part and the sleeve can be achieved only after the nut is tightened (that is, the bolt rod cannot be disengaged until it reaches the position), thereby realizing the monitoring of the bolt connection tightening by mechanical means.
