Description

Technical Field

[0001] This utility model relates to the field of locking machine technology, and in particular to a locking mechanism for a locking machine. Background Technology

[0002] A screw fastening machine is an automated device primarily used to replace traditional manual screw tightening, improving production efficiency and reducing production costs. It is widely used in various industrial fields.

[0003] Existing screw fastening machines typically use a drive mechanism to rotate a wrench and tighten screws. However, when tightening screws of different sizes, operators must remove the wrench and manually install a suitable wrench onto the drive mechanism. This method is inefficient, and after use, the drive shaft is usually exposed to the external environment, making it susceptible to damage from impacts. Therefore, we propose a new screw fastening mechanism for this machine. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a locking mechanism for a locking machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a locking mechanism for a locking machine is designed, including a mounting base, one side of which is connected to the machine frame through an adjustment mechanism;

[0006] The bottom of the mounting base is rotatably connected to a drive shaft, and the top of the drive shaft is connected to a drive motor. The drive motor is fixed to the top of the mounting base, and a strip mounting plate is also provided at the bottom of the mounting base. Several wrenches are rotatably connected to the bottom of the strip mounting plate. The top of the wrenches extends above the strip mounting plate, and each wrench has a square groove on its top. A square connector that matches the square groove is installed at the bottom of the drive shaft.

[0007] The top two sides of the strip mounting plate are provided with skirts, and each skirt is equipped with a guide rail at the top. Each guide rail is slidably connected to a pair of guide sleeves via a slider. Each guide sleeve is slidably connected to a guide rod, the top of which extends above the guide sleeve. The top of each guide rod is fixed to both sides of the mounting base by a fixing plate.

[0008] Two sliders on the same side are connected by a strip connecting plate. The top of each strip connecting plate is connected to the mounting base through a telescopic mechanism. Each strip connecting plate has a threaded through hole at the top, and a locking bolt is installed inside the threaded through hole. Each guide rail has several positioning grooves at the top. When the locking bolt is tightened, the bottom of the locking bolt passes through the threaded through hole and extends into the corresponding positioning groove.

[0009] Each guide sleeve has a sliding sleeve coaxially fitted on its side, and each sliding sleeve has a support ring extending from its bottom. The support rings are connected by a protective cover, and the top of the protective cover is fixed to the bottom of the mounting base and the fixing plate, while the drive shaft is located inside the protective cover.

[0010] Preferably, when the telescopic mechanism is extended to its maximum length, there is a gap between the bottom end of the square joint and the top end of the square groove.

[0011] Preferably, each guide rod has an anti-detachment block installed at its bottom, the edge of the anti-detachment block is fitted with the inner wall of the guide sleeve with a clearance, and each guide sleeve has a limit ring installed at its inner top, the bottom of the limit ring abutting against the top of the anti-detachment block.

[0012] Preferably, each pair of positioning slots is aligned with the corresponding wrench.

[0013] Preferably, the protective cover is made of rubber material.

[0014] Preferably, each sliding sleeve has an opening groove at its top, and a locking nut is fitted on the side of the sliding sleeve. The locking nut is threadedly connected to the sliding sleeve, and when the locking nut is tightened, the inner wall of the sliding sleeve and the side of the guide sleeve are tightly abutted together.

[0015] Preferably, when the wrench located at one end of the strip mounting plate is moved below the square connector, the slider is located on the guide rail.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] By moving the strip mounting plate along the guide rail, the corresponding wrench can be moved to the bottom of the drive shaft according to the type of screw to be installed. The square connector under the drive shaft is connected to the square slot on the top of the wrench through the telescopic mechanism. This allows for the tightening of different types of screws and improves the performance.

[0018] By moving the sliding sleeve along the guide sleeve, the protective cover can be made to cover the drive shaft, thus isolating the drive shaft from the external environment, protecting the drive shaft and improving the protection effect. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-4 A locking mechanism for a locking machine includes a mounting base 1. One side of the mounting base 1 is connected to a frame 22 via an adjustment mechanism. The adjustment mechanism is a linear drive module or another linear transmission mechanism, such as... Figure 5 As shown, this allows for easy adjustment of the position of mounting base 1 as needed.

[0027] like Figure 2 and Figure 3 As shown, a drive shaft 16 is rotatably connected to the bottom of the mounting base 1, and a drive motor 2 is connected to the top of the drive shaft 16. The drive motor 2 is fixed to the top of the mounting base 1. A strip mounting plate 11 is also provided at the bottom of the mounting base 1. Several wrenches 9 are rotatably connected to the bottom of the strip mounting plate 11. The top of the wrenches 9 extends above the strip mounting plate 11. The bottom of the wrenches 9 is made of magnetic material, so that when the operator places the screw to be installed on the bottom of the wrench 9, the wrench 9 can attract and fix the screw.

[0028] like Figure 1 and Figure 4 As shown, the top two sides of the strip mounting plate 11 are provided with skirts 12. Each skirt 12 is equipped with a guide rail 13 at its top. Each guide rail 13 is slidably connected to a pair of guide sleeves 4 via a slider 10. Each guide sleeve 4 is slidably connected to a guide rod 3 inside. The top of the guide rod 3 extends above the guide sleeve 4, and the top of each guide rod 3 is fixed to both sides of the mounting base 1 by a fixing plate 15. Through the cooperation of the guide sleeves 4 and the guide rods 3, the strip mounting plate 11 can be limited, so that the strip mounting plate 11 remains stable.

[0029] like Figure 2 and Figure 3 As shown, two sliders 10 located on the same side are connected by a strip connecting plate 7. The top of each strip connecting plate 7 is connected to the mounting base 1 by a telescopic mechanism 26. The telescopic mechanism 26 is one of an electric push rod, a cylinder, or a hydraulic rod. Each wrench 9 has a square slot 18 on its top. The bottom of the drive shaft 16 is equipped with a square connector 17 that matches the square slot 18. In actual use, the position of the strip mounting plate 11 can be adjusted by the telescopic mechanism 26. This allows the square connector 17 at the bottom of the drive shaft 16 to be inserted into the corresponding square slot 18, driving the wrench 9 to rotate and tighten the bolt.

[0030] It should be noted that, as Figure 2 As shown, when the telescopic mechanism 26 is extended to its longest length, there is a gap between the bottom end of the square connector 17 and the top end of the square groove 18, so that when the wrench 9 is adjusted according to the type of screw to be tightened, the square connector 17 will not collide with the wrench 9.

[0031] like Figure 3 As shown, each strip connecting plate 7 has a threaded through hole 25 at its top, and a locking bolt 8 is provided inside each threaded through hole 25. Each guide rail 13 has several positioning grooves 24 at its top. When the locking bolt 8 is tightened, the bottom of the locking bolt 8 passes through the threaded through hole 25 and extends into the corresponding positioning groove 24. Each pair of positioning grooves 24 is aligned with the corresponding wrench 9. In actual use, by moving the strip mounting plate 11 along the guide rail 13, the wrench 9 corresponding to the type of screw to be installed is moved to below the drive shaft 16. Then, the locking bolt 8 is tightened so that the bottom of the locking bolt 8 is inserted into the positioning groove 24, fixing the wrench 9 in place, thus completing the adjustment.

[0032] like Figure 1 As shown, each guide sleeve 4 has a sliding sleeve 21 coaxially fitted on its side. Each sliding sleeve 21 has a support ring 20 extending from its bottom. The support rings 20 are connected by a protective cover 6. The top of the protective cover 6 is fixed to the bottom of the mounting base 1 and the fixing plate 15. The drive shaft 16 is located inside the protective cover 6. The protective cover 6 is made of rubber material or other flexible material. In actual use, after processing, the operator can cover the drive shaft 16 through the protective cover 6 to protect the drive shaft 16.

[0033] It should be noted that, as Figure 1 and Figure 4As shown, each sliding sleeve 21 has an opening groove 14 on its top. A locking screw 5 is also fitted on the side of the sliding sleeve 21. The locking screw 5 is threadedly connected to the sliding sleeve 21. When the locking screw 5 is tightened, the inner wall of the sliding sleeve 21 is tightly pressed against the side of the guide sleeve 4. In actual use, the operator can move the sliding sleeve 21 upwards to the upper end of the guide sleeve 4, and then tighten the locking screw 5 to fix the sliding sleeve 21. This will cause the protective cover 6 to retract, exposing the drive shaft 16, which makes it convenient for the user to adjust the position of the wrench 9.

[0034] Specifically, in use, the operator places the workpiece on the frame 22, then adjusts the mounting base 1 to a preset position using the adjustment mechanism. Next, the operator horizontally moves the strip mounting plate 11, causing the wrench 9, matching the screw type, to move below the drive shaft 16. Then, the operator tightens the locking bolt 8, causing its bottom to move into the corresponding positioning groove 24, fixing the strip mounting plate 11 in place. Finally, the operator controls the telescopic mechanism 26 to retract, causing the strip mounting plate 11 to move upwards, thus moving the top of the wrench 9. The square groove 18 is fitted onto the square connector 17 installed at the bottom of the drive shaft 16. Then, the operator fixes the screw to the bottom of the wrench 9 and moves the bottom of the wrench 9 to the preset position on the workpiece through the adjustment mechanism. Then, the drive motor 2 drives the drive shaft 16 to rotate, and the drive shaft 16 drives the wrench 9 to rotate, fixing the screw to the workpiece. After processing, the operator can loosen the locking sleeve 5. The sliding sleeve 21 can slide along the guide sleeve 4 under the action of gravity, so that the protective cover 6 covers the drive shaft 16, thus isolating the drive shaft 16 from the external environment and protecting the drive shaft 16.

[0035] Furthermore, such as Figure 4 As shown, each guide rod 3 has an anti-detachment block 19 installed at its bottom. The edge of the anti-detachment block 19 is fitted with the inner wall of the guide sleeve 4 with a clearance. Each guide sleeve 4 has a limit ring 23 installed at its inner top. The bottom of the limit ring 23 abuts against the top of the anti-detachment block 19. In actual use, the cooperation between the limit ring 23 and the anti-detachment block 19 can limit the guide rod 3 and the guide sleeve 4, preventing the guide rod 3 from detaching from the guide sleeve 4.

[0036] Furthermore, when the wrench 9 located at one end of the strip mounting plate 11 is moved below the square connector 17, the slider 10 is located on the guide rail 13. In this way, during use, the guide sleeve 4 will be connected to the guide rail 13 through the slider 10, so that the stability of the strip mounting plate 11 and the wrench 9 is not hindered.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
