Description

Technical Field

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

[0002] Bolt fastening machines play a crucial role in mechanical assembly and maintenance. They are widely used in automobile manufacturing, aerospace, bridge construction, and the assembly of various mechanical equipment to ensure a secure connection between components. However, existing bolt fastening devices have some significant shortcomings in use, particularly in replacing bolt heads.

[0003] Traditional bolt fastening devices often employ a fixed locking structure. This means that users need to frequently adjust or replace the bolt locking sleeve to accommodate changes in bolt heads when dealing with bolts of different sizes or types. This operation is not only cumbersome but also inefficient, significantly increasing the labor intensity and time costs for workers.

[0004] Therefore, based on this, a design or technical improvement is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings and provide a bolt fastening device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a bolt fastening device, including a first housing and a bolt locking sleeve, wherein an electric push rod is provided inside the first housing, and a handle is provided at the top of the electric push rod; a second housing is fixedly connected to the bottom of the first housing; a third housing is fixedly installed at the bottom of the second housing; a third motor is provided inside the second housing; a linkage rod is fixedly connected to the output shaft of the third motor; a connecting plate is provided at the end of the linkage rod; and a clamping mechanism is provided on the connecting plate.

[0007] The clamping mechanism includes an annular shell fixedly mounted on a connecting plate. A circular plate is rotatably mounted on the inner wall of the annular shell. Multiple sets of chucks are provided on one side of the circular plate, and multiple sets of toothed blocks are fixedly mounted on the other side of the circular plate. Multiple sets of movable blocks are provided on the circular plate, and a clamping block is fixedly mounted on one end of each set of movable blocks. Multiple sets of toothed blocks are fixedly mounted on one side of each set of movable blocks, and the multiple sets of toothed blocks mesh with the multiple sets of chucks.

[0008] The annular shell is provided with a drive assembly for controlling the rotation of the circular plate;

[0009] The second outer casing is provided with a heat dissipation component for heat dissipation inside the second outer casing;

[0010] A third housing protection component is provided on the first housing for the protection of the clamping mechanism.

[0011] Furthermore, the drive assembly includes a first motor mounted on the annular shell, and the output shaft of the first motor is fixedly mounted with bevel gears, which mesh with multiple sets of tooth blocks. A fixed shell is provided at the bottom end of the annular shell.

[0012] Furthermore, a fixing frame is provided on the second housing, and the heat dissipation assembly includes multiple sets of mounting brackets fixedly installed in the fixing frame. A shaft is rotatably provided on each of the multiple sets of mounting brackets, and multiple sets of fan blades are fixedly installed on the shaft. A second motor is fixedly installed on one side of each of the multiple sets of mounting brackets, and the output shaft of the second motor is fixedly connected to one end of the shaft.

[0013] Furthermore, a dustproof net is fixedly installed on one side of the fixed frame.

[0014] Furthermore, the electric push rod is provided with two sets of fixing plates, and the protective assembly includes a protective cover that is slidably disposed on the third housing. Two sets of long rods are fixedly installed on the top of the protective cover, and the tops of the two sets of long rods are fixedly connected to the two sets of fixing plates.

[0015] Furthermore, the bottom end of the fixed shell is provided with multiple sets of limiting square tubes, and the inner wall of the multiple sets of limiting square tubes is slidably provided with long plates, and the end of the long plate is fixedly connected to the end of the clamping block, and the end of the long plate is fixedly installed with a limiting plate.

[0016] Furthermore, the outer surface of the fixed shell is provided with multiple sets of limiting grooves, and movable blocks are slidably arranged in the multiple sets of limiting grooves.

[0017] Furthermore, two sets of limiting tubes are fixed on the outer surface of the second housing, and a long rod is slidably installed on the inner wall of the limiting tube.

[0018] Furthermore, a protective shell is fixedly installed on the outer surface of the connecting plate.

[0019] Compared with existing technologies, the beneficial effects of this solution are:

[0020] 1. By starting the first motor, the bevel gear is driven to mesh with the toothed block on the circular plate, realizing the rotation of the circular plate and the chuck on it. This drives the movable block to move precisely in a straight line along the limiting groove on the fixed shell, thereby driving the clamping block to slide smoothly through the long plate in the limiting square tube. This improves the efficiency of the bolt locking operation and ensures the accuracy of the spacing adjustment between the clamping blocks. It provides a strong guarantee for the accurate placement and clamping of the bolt locking sleeve, so that the bolt locking sleeve can be replaced quickly and the work efficiency can be improved.

[0021] 2. The second motor drives the fan blades to rotate, providing effective heat dissipation for the interior of the second housing. This design not only prevents critical components such as the motor from being damaged by overheating, but also ensures the stability and reliability of the entire device under long-term, high-load operation.

[0022] 3. By driving the electric push rod, the fixed plate is smoothly lowered, which in turn drives the long rod securely connected to it to descend synchronously, ultimately causing the protective cover to move precisely downwards and cover the clamping mechanism. This series of precise actions ensures that the protective cover can accurately reach the predetermined position, creating a relatively closed and safe protective space for the clamping mechanism. This effectively avoids accidental interference or damage to the clamping mechanism caused by external factors, greatly improving the accuracy and effectiveness of the protection.

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] like Figure 1-7 The bolt fastening device shown includes a first housing 1 and a bolt locking sleeve 115. An electric push rod 2 is disposed inside the first housing 1, and a handle 3 is provided at the top of the electric push rod 2. A second housing 4 is fixedly connected to the bottom of the first housing 1, and a third motor 211 is disposed inside the second housing 4. A linkage rod 8 is fixedly connected to the output shaft of the third motor 211, and a connecting plate 9 is provided at the end of the linkage rod 8. A clamping mechanism is provided on the connecting plate 9. The clamping mechanism includes an annular shell 911 fixedly disposed on the connecting plate 9. A circular plate 812 is rotatably disposed on the inner wall of the annular shell 911. One side of the circular plate 812... Multiple sets of chucks 813 are provided, and multiple sets of toothed blocks 814 are fixedly installed on the other side of the circular plate 812. Multiple sets of movable blocks 914 are provided on the circular plate 812, and clamping blocks 915 are fixedly installed on one end of the multiple sets of movable blocks 914. Multiple sets of toothed blocks 814 are fixedly installed on one side of the multiple sets of movable blocks 914, and the multiple sets of toothed blocks 814 mesh with the multiple sets of chucks 813. A drive assembly is provided on the annular shell 911 for controlling the rotation of the circular plate 812. A heat dissipation assembly is provided on the second outer shell 4 for heat dissipation inside the second outer shell 4. A protective assembly is provided on the third outer shell 7 for the protective function of the clamping mechanism.

[0034] In one embodiment, the driving assembly includes a first motor 711 mounted on an annular shell 911, and a bevel gear 712 is fixedly mounted on the output shaft of the first motor 711. The bevel gear 712 meshes with multiple sets of toothed blocks 814. A fixed shell 912 is provided at the bottom end of the annular shell 911. When the first motor 711 is started, the bevel gear 712 is driven to rotate. The bevel gear 712 meshes with the toothed blocks 814 on one side of the circular plate 812, causing the circular plate 812 to rotate inside the annular shell 911. The rotation of the circular plate 812 causes multiple sets of chucks 813 to rotate accordingly. These chucks 813 mesh with the toothed blocks 814 on the movable block 914, thereby pushing the movable block 914 to move linearly along the limiting groove 917 on the fixed shell 912.

[0035] In one embodiment, a fixing frame 5 is provided on the second housing 4. The heat dissipation assembly includes multiple sets of mounting brackets 611 fixedly installed in the fixing frame 5. A shaft 612 is rotatably mounted on the multiple sets of mounting brackets 611, and multiple sets of fan blades 613 are fixedly installed on the shaft 612. A second motor 614 is fixedly installed on one side of the multiple sets of mounting brackets 611, and the output shaft of the second motor 614 is fixedly connected to one end of the shaft 612. The rotation is driven by the second motor 614, which effectively accelerates the airflow and provides efficient heat dissipation for the interior of the second housing 4, preventing overheating of internal electronic components and extending the service life of the equipment.

[0036] In one embodiment, a dustproof net 6 is fixedly installed on one side of the fixed frame 5. The dustproof net 6 can effectively block external dust and debris from entering the fixed frame 5, keep the fan blades and internal components clean, and avoid poor heat dissipation and malfunctions caused by blockage.

[0037] In one embodiment, the electric push rod 2 is provided with two sets of fixing plates 111. The protective component includes a protective cover 114 that is slidably disposed on the third housing 7. Two sets of long rods 112 are fixedly installed on the top of the protective cover 114. The top of the two sets of long rods 112 is fixedly connected to the two sets of fixing plates 111. The connection between the long rods 112 and the two sets of fixing plates 111 allows the protective component to move with the electric push rod 2, thereby providing effective protection for the clamping mechanism during carrying.

[0038] In one embodiment, the bottom end of the fixed shell 912 is provided with multiple sets of limiting square tubes 913. Long plates 916 are slidably mounted on the inner walls of the multiple sets of limiting square tubes 913, and the ends of the long plates 916 are fixedly connected to the ends of the clamping block 915. Limiting plates 918 are fixedly installed on the ends of the long plates 916. The long plates 916, slidably mounted on the inner walls of the multiple sets of limiting square tubes 913, provide precise guidance and stable support for the clamping block 915, ensuring that the clamping block remains straight and stable during movement, effectively improving the clamping accuracy and stability. Simultaneously, the limiting plates 918 at the ends of the long plates 916 serve a limiting function, preventing the clamping block from exceeding a predetermined range during movement.

[0039] In one embodiment, the outer surface of the fixed shell 912 is provided with multiple sets of limiting grooves 917, and a movable block 914 is slidably disposed in the multiple sets of limiting grooves 917. The multiple sets of limiting grooves 917 provide a clear sliding path for the movable block 914, so that the movable block 914 can move smoothly and accurately along the limiting grooves, thereby driving the clamping block to achieve a precise clamping action.

[0040] In one embodiment, two sets of limiting tubes 113 are fixed on the outer surface of the second housing 4, and a long rod 112 is slidably installed on the inner wall of the limiting tube 113. The limiting tube 113 provides a stable movement track for the long rod 112, effectively preventing the long rod 112 from shaking or deviating during movement.

[0041] In one embodiment, a protective shell 811 is fixedly installed on the outer surface of the connecting plate 9. The protective shell 811 is used to protect the first motor 711.

[0042] The specific workflow of this plan is as follows:

[0043] First, the first motor 711 is started, driving the bevel gear 712 to begin rotating. The bevel gear 712 meshes with the toothed block 814 on one side of the circular plate 812, causing the circular plate 812 to rotate inside the annular shell 911. The rotation of the circular plate 812 causes multiple sets of chucks 813 to rotate accordingly. These chucks 813 mesh with the toothed block 814 on the movable block 914, thereby pushing the movable block 914 to move linearly along the limiting groove 917 on the fixed shell 912.

[0044] The movement of the movable block 914 causes the clamping block 915 to slide smoothly in the limiting square tube 913 through the long plate 916, so that the distance between the clamping blocks 915 gradually increases, so that the bolt locking sleeve 115 can be inserted into it.

[0045] Once the bolt locking sleeve 115 is in place, the first motor 711 is driven in reverse to make the clamping block 915 gradually approach and clamp the bolt locking sleeve 115, ensuring that it will not fall off in subsequent operations.

[0046] After the clamping block 915 successfully clamps the bolt locking sleeve 115, the entire device moves directly above the bolt to ensure that the bolt locking sleeve 115 is aligned with the bolt. The third motor 211 is then started to drive the linkage rod 8 to rotate. The rotation of the linkage rod 8 causes the connecting plate 9 and its clamping mechanism to rotate together.

[0047] As the connecting plate 9 rotates, the bolt locking sleeve 115 gradually tightens onto the bolt until the predetermined tightness is achieved.

[0048] During the entire fastening process, the second motor 614 drives the fan blades 613 to rotate, generating airflow to provide heat dissipation for the interior of the second housing 4 and prevent the motor and other components from overheating.

[0049] The electric push rod 2 is driven to move, pushing the connected fixed plate 111 to descend smoothly. Since one end of the long rod 112 is firmly connected to the fixed plate 111, the long rod 112 also descends synchronously with the fixed plate 111 as it descends. The other end of the long rod 112 is tightly connected to the protective cover 114; therefore, the descent of the long rod 112 directly causes the protective cover 114 to move downwards until it accurately covers the clamping mechanism. This creates a relatively enclosed and safe protective space for the clamping mechanism.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
