Abstract
Description
Technical Field
[0001] This utility model relates to the field of scaffolding technology, specifically to an automatic screw-tightening device. Background Technology
[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It can be classified according to its location as external scaffolding and internal scaffolding; according to its material as wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; and according to its structural form as pole-type scaffolding, bridge-type scaffolding, frame-type scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding.
[0003] Adjusting screws used on scaffold steel frames (such as...) Figure 1 As shown, to facilitate use by on-site construction personnel, during the production of the adjusting screw, connecting part A (including the nut and the extension plate opposite to the nut ring) needs to be screwed to the middle of the screw B. Since the screw B is relatively long, it takes nearly 100 turns to screw connecting part A to the middle of the screw B. Currently, this is mainly done manually, which consumes a lot of manpower and is inefficient.
[0004] In view of this, there is an urgent need for an automatic screw-twisting device. Utility Model Content
[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] An automatic screwing device includes: a frame, on which a slide, a screw clamping mechanism, a fixed seat, and a drive mechanism are provided. The screw clamping mechanism is disposed on the slide, and the slide is slidably disposed on the frame along a straight line. The screw clamping mechanism is used to clamp one end of a screw.
[0008] The mounting base is used to fix the connecting parts;
[0009] The lead screw at the lead screw clamping mechanism is coaxial with the nut of the connecting part at the fixed seat;
[0010] The drive mechanism is used to drive the lead screw at the lead screw clamping mechanism to rotate.
[0011] Its further feature is that,
[0012] The top surface of the frame is provided with two parallel slide rails, the slide block is disposed on the slide rails, and the fixed seat is disposed at one end of the slide rails.
[0013] The lead screw clamping mechanism is a three-jaw chuck, with the clamping end of the three-jaw chuck facing the side of the fixed base.
[0014] The slide is provided with a mounting plate, and a rotating shaft is rotatably mounted on the mounting plate. The three-jaw chuck is mounted on the rotating shaft.
[0015] The drive mechanism includes a motor, a first sprocket, a second sprocket, and a chain. The motor is mounted on a slide, the first sprocket is coaxially mounted on the output end of the motor, the second sprocket is sleeved on a rotating shaft, and the chain is sleeved on the first sprocket and the second sprocket.
[0016] The slide is provided with a cover, and the drive mechanism is located inside the cover.
[0017] Both sides of the top of the fixing base are provided with slots that are adapted to the extension plates on both sides of the connector.
[0018] The mounting base is fixed to the frame with bolts.
[0019] The fixing base is rotatably equipped with anti-detachment pins at the top of both slots.
[0020] An electrical cabinet is installed on one side of the rack.
[0021] The above-described structure of this utility model can achieve the following beneficial effects:
[0022] In use, first rotate the connector onto the lead screw, then fix one end of the lead screw through the lead screw clamping mechanism. Then slide the slide on the frame to fix the connector on the fixed seat. At this time, drive the lead screw at the lead screw clamping mechanism to rotate through the drive mechanism, so that the connector is screwed toward the middle of the lead screw, thus completing the screwing of the connector. It takes about 45 seconds to manually screw one lead screw, while it takes about 22 seconds for the machine to screw it, which doubles the efficiency and saves manpower.
[0023] Furthermore, when manually turning the screw, if there is zinc dross on it, it is necessary to stop and process the zinc dross. The motor of the equipment has a large torque, so most of the zinc dross can pass through directly and be removed at the same time. Attached Figure Description

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 should fall within the protection scope of the present invention.
[0030] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.
[0031] The following is combined with Figures 2-4 This application is described in further detail.
[0032] refer to Figure 2 An automatic screw-twisting device is shown, comprising: a frame 1, on which a slide 2, a screw clamping mechanism 3, a fixed seat 4, and a drive mechanism 5 are mounted. The screw clamping mechanism 3 is mounted on the slide 2, which slides linearly on the frame 1. In use, the connector is first rotated onto the screw (manually screwed 2-3 turns), and then one end of the screw is fixed by the screw clamping mechanism 3. The slide 2 then slides on the frame 1, fixing the connector to the fixed seat 4. At this time, the drive mechanism 5 drives the screw at the screw clamping mechanism 3 to rotate, causing the connector to be screwed toward the middle of the screw (during the screwing process, the slide 2 slides on the frame 1), thus completing the screwing of the connector. Manually screwing one screw takes about 45 seconds, while the device screws it in about 20 seconds, doubling the efficiency and saving labor.
[0033] like Figure 2 As shown, in order to limit the movement of the slide block 2, two parallel slide rails 11 are provided on the top surface of the frame 1. The slide block 2 is placed on the slide rail 11, and the fixed seat 4 is placed at one end of the slide rail 11. In this way, the movement of the slide block 2 is limited and guided by the two slide rails 11, so that the slide block 2 can make linear reciprocating motion on the frame 1.
[0034] like Figure 2 and Figure 3 As shown, in order to clamp the end of the lead screw, the lead screw clamping mechanism 3 is a three-jaw chuck. The clamping end of the three-jaw chuck faces the fixed seat 4. The slide 2 is provided with a mounting plate 21, and a rotating shaft 6 is rotatably provided on the mounting plate 21. The three-jaw chuck is set on the rotating shaft 6. In this way, the end of the lead screw is fixed, and the lead screw can be rotated by rotating the three-jaw chuck.
[0035] like Figure 3 As shown, the drive mechanism 5 specifically includes a motor 51, a first sprocket 52, a second sprocket 53, and a chain 54. The motor 51 is mounted on the slide block 2. The first sprocket 52 is coaxially mounted on the output end of the motor 51. The second sprocket 53 is sleeved on the rotating shaft 6. The chain 54 is sleeved on the first sprocket 52 and the second sprocket 53. In this way, the motor 51 provides power to make the rotating shaft 6 rotate, which in turn makes the three-jaw chuck rotate and drives the lead screw to rotate.
[0036] Further optimizations include, for example Figure 1 As shown, a cover 7 is provided on the slide 2, and the drive mechanism 5 is located inside the cover 7. The cover 7 is fitted onto the drive mechanism 5 to protect the drive mechanism 5 and prevent foreign objects from entering.
[0037] like Figure 4 As shown, the top two sides of the fixed base 4 are provided with slots 41 that are adapted to the extension plates on both sides of the connector. When fixing the connector, the two extension plates on the ring side of the connector are respectively locked in the two slots 41 to fix the connector. In order to prevent the connector from detaching from the fixed base 4 when twisting, the fixed base 4 is rotatably provided with anti-detachment pins 42 on the top of the two slots 41. After the connector is placed in the fixed base 4, the anti-detachment pins 42 are rotated so that the anti-detachment pins 42 are placed horizontally on the top of the connector to restrict the connector. In addition, in order to facilitate the replacement of the fixed base 4, the fixed base 4 is fixed to the frame 1 by bolts.
[0038] In a further optimization, the electrical cabinet in this embodiment is located on one side of the rack 1.
[0039] The working principle of this utility model is as follows: When in use, the connector is first rotated onto the lead screw, and then one end of the lead screw is fixed by the lead screw clamping mechanism 3. Then, the slide 2 slides on the frame 1 to fix the connector on the fixed seat 4. At this time, the lead screw at the lead screw clamping mechanism 3 is driven to rotate by the drive mechanism 5, so that the connector is screwed toward the middle of the lead screw, thus completing the screwing of the connector. It takes about 45 seconds to manually screw one lead screw, while it takes about 20 seconds for the equipment to screw one lead screw, which doubles the efficiency and saves manpower. A person can only screw one lead screw at a time. With the equipment, one person can operate two machines at the same time. The person only needs to be responsible for loading and unloading materials.
[0040] It uses a high-torque stepper motor as the power source and transmits power through a sprocket and chain mechanism, resulting in a simple and compact overall structure.
[0041] Furthermore, when manually turning the screw, if there is zinc dross on it, it is necessary to stop and process the zinc dross. The motor 51 of the equipment has a large torque, so most of the zinc dross can pass through directly and be removed at the same time.
[0042] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
