Description

Technical Field

[0001] The utility model belongs to the technical field of safety belt mandrel production, and in particular relates to a mandrel grabbing and rotating mechanism. Background Art

[0002] On the production line of seat belt mandrels, in order to replace or adjust the direction of the mandrel, the mandrel needs to be steered. However, the current production line of seat belt mandrels still has workers directly working on the production line, which includes steering adjustments of the mandrel.

[0003] Workers directly contact the core shaft on the carrier, which is prone to the risk of injury. Manual operation is slow and inefficient, and cannot meet the needs of large-scale production. Manual operation is easily affected by factors such as fatigue and technical level, resulting in unstable product quality, requiring more manpower, increasing labor costs, and also reducing production efficiency. Therefore, it is necessary to use an automated core shaft grasping and rotating mechanism and a steering adjustment device on the production line of seat belt core shafts, which can better improve production efficiency, ensure product quality, reduce production costs and reduce safety risks. In view of this, a core shaft grasping and rotating mechanism is proposed. Utility Model Content

The piston rod of the clamping cylinder passes through the circular box and is fixedly connected to the mounting block. The outer clamping plate is fixed on the mounting block, and the action of the clamping cylinder drives the mounting block to slide inward along the guide groove on the circular box, thereby driving the outer clamping plate to move toward the direction of the inner clamping plate, so that the outer clamping plate cooperates with the inner clamping plate to clamp the seat belt core shaft.

[0009] Preferably, the core shaft grasping and rotating mechanism also includes a lifting cylinder, the piston rod end of the lifting cylinder is connected to the lifting plate through a fisheye joint, and the rotating cylinder is fixed on the lifting plate. The lifting cylinder is driven by the action of the lifting cylinder to move the rotating cylinder and the clamp downward into the clamping station of the carrier, or the lifting cylinder is driven by the action of the lifting cylinder to move the rotating cylinder, the clamp and the seat belt core shaft clamped on the clamp upward into the rotating station.

[0010] The lifting rod drives the rotary cylinder and the clamping claw to move up and down, so that the clamping claw can move into the clamping station or the rotating station, so that the mechanism has the dual operation of grasping and rotating functions, thereby improving the versatility of the mechanism.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are:

[0015] The core shaft grasping and rotating mechanism, the clamping cylinder can accurately control the movement of the inner clamping plate and the outer clamping plate, so that the clamping of the seat belt core shaft is more accurate and the product quality is improved. By introducing the rotating cylinder, the seat belt core shaft and the clamping claw can be driven to rotate.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The following is combined with Figure 1-5 To further explain this application in detail,

[0025] The embodiment of the present application discloses a spindle grabbing and rotating mechanism, including a clamping jaw 1 and a rotating cylinder 4, wherein the clamping jaw 1 is provided with two groups and includes an outer clamping plate 101 and an inner clamping plate 102, wherein the inner clamping plate 102 is a T-shaped plate that is movably inserted into a hole 3 on a seat belt spindle 2, wherein the outer clamping plate 101 is located outside both ends of the seat belt spindle 2 and is pushed by a clamping cylinder and cooperates with the inner clamping plate 102 to clamp the seat belt spindle 2 from both ends of the seat belt spindle 2;

[0026] The output shaft end of the rotary cylinder 4 is fixedly connected to the circular box 5 on which the clamping cylinder is installed. The rotary cylinder 4 drives the circular box 5, the clamping claw 1 and the seat belt core shaft 2 clamped on the clamping claw 1 to rotate.

[0027] The spindle grabbing and rotating mechanism realizes the clamping and positioning of the seat belt spindle 2 through the movable insertion and pushing out of the clamping claw 1 (usually the inner clamping plate 102 and the outer clamping plate 101) in cooperation with the force of the clamping cylinder. The inner clamping plate 102 is movably inserted into the hole 3 on the seat belt spindle 2, and the outer clamping plate 101 is located outside the two ends of the seat belt spindle 2. The clamping cylinder pushes and cooperates with the inner clamping plate 102 to clamp the seat belt spindle 2 from both ends of the seat belt spindle 2. This design allows the inner clamping plate 102 and the outer clamping plate 101 to form a tight fit in space, thereby realizing high-precision positioning and grabbing of the seat belt spindle 2.

[0028] The output shaft end of the rotary cylinder 4 is fixedly connected to the circular box 5 on which the clamping cylinder is installed, and the rotary cylinder 4 drives the circular box 5, the clamping jaw 1, and the safety belt core shaft 2 clamped on the clamping jaw 1 to rotate. This design enables the entire mechanism to achieve the entire grasping and rotating action under the drive of the rotary cylinder 4.

[0029] Due to the close fit between the inner and outer clamping plates 102, 101, and the high-precision control of the clamping cylinder, high-precision positioning and grasping of the seat belt core shaft 2 can be achieved. The entire mechanism can realize rotation and grasping actions under the drive of the rotating cylinder 4, thereby improving the grasping efficiency. The design of the entire mechanism is concise and clear, and the operation is relatively easy.

[0030] The inner clamping plate 102 is fixed to the bottom of the circular box 5, and the clamping cylinder is located inside the circular box 5. This layout makes the entire mechanism compact and occupies a small space, which is suitable for installation on the production line. The piston rod of the clamping cylinder passes through the circular box 5 and is fixedly connected to the mounting block 6. The outer clamping plate 101 is fixed on the mounting block 6. The clamping cylinder drives the mounting block 6 to slide inward along the guide groove on the circular box 5, and then drives the outer clamping plate 101 to move in the direction of the inner clamping plate 102, so that the outer clamping plate 101 cooperates with the inner clamping plate 102. The clamping of the seat belt core shaft 2 realizes an automated clamping process and reduces dependence on manpower. The clamping cylinder can accurately control the movement of the inner clamping plate 102 and the outer clamping plate 101, making the clamping of the seat belt core shaft 2 more accurate and improving the quality of the product. Through the action of the clamping cylinder, the outer clamping plate 101 can quickly cooperate with the inner clamping plate 102 to clamp the seat belt core shaft 2, thereby improving production efficiency. Since the entire clamping and rotation process is automatically completed by the machine, workers do not need to directly contact the core shaft being operated, which greatly improves the safety of the operation.

[0031] like Figure 2-3As shown, the core shaft grasping and rotating mechanism also includes a lifting cylinder 7, the piston rod end of the lifting cylinder 7 is connected to the lifting plate 9 through a fisheye joint 8, and the rotating cylinder 4 is fixed on the lifting plate 9. The lifting cylinder 7 is driven by the rotating cylinder 4 and the clamp 1 to move down into the clamping station of the carrier 15, or the lifting cylinder 7 is driven by the rotating cylinder 4, the clamp 1 and the seat belt core shaft 2 clamped on the clamp 1 to move up into the rotating station.

[0032] By driving the rotary cylinder 4 and the clamping jaw 1 to move up and down through the action of the lifting rod, the clamping jaw 1 can be moved into the clamping station or the rotating station, so that the mechanism has the dual operation of grasping and rotating functions, which improves the versatility of the mechanism. By controlling the up and down movement of the clamping jaw 1 through the lifting cylinder 7, it can switch freely between different workstations, fully utilize the space, and improve the work efficiency of the production line. After the introduction of the lifting cylinder 7, the up and down movement of the rotary cylinder 4 and the clamping jaw 1 can be achieved by controlling the lifting rod, and operations such as clamping the seat belt core shaft 2 and entering the clamping station or the rotating station can be completed. The operation is flexible and convenient. The introduction of the lifting cylinder 7 allows the mechanism to switch freely between different workstations, and different operations can be completed quickly, thereby improving production efficiency and the operating efficiency of the entire production line. Through the action control of the lifting cylinder 7, the operator does not need to directly contact the core shaft and the clamping jaw 1 being operated, which reduces safety risks and improves work safety.

[0033] like Figure 4 As shown, a slider 10 is provided on the back of the lifting plate 9 , and the slider 10 cooperates with the slide rail 12 on the mounting plate 11 to guide the sliding. The lifting cylinder 7 is fixed on the mounting plate 11 , and the mounting plate 11 is fixed at the center position of the bracket 13 .

[0034] The lifting plate 9 can be guided to move stably, thereby improving the stability of the operation of the entire mechanism. The lifting plate 9 and the slider 10 can slide on the slide rail 12 by controlling the action of the lifting cylinder 7 to achieve the upward or downward movement of the entire mechanism, thereby improving the ease of operation.

[0035] like Figure 5 As shown, the bracket 13 includes a horizontal plate 1301, a fixing seat 1303 fixed at both ends of the horizontal plate 1301 and used to fix the top ends of the two optical axes 1302, and a fixing ring 1304 fixing the bottom ends of the two optical axes 1302, and the fixing ring 1304 is arranged on a mounting seat 1305.

[0036] The design of the bracket 13 enables the entire mechanism to stably support the two optical axes 1302 and the cross plate 1301, thereby improving the structural stability of the entire mechanism. The design of the fixing seat 1303 and the fixing ring 1304 can firmly fix the two optical axes 1302, ensuring that they will not move or tilt during the production process, thereby improving the quality of the product.

[0037] like Figure 2-3 As shown, a buffer 14 is fixedly provided on the lifting plate 9 to buffer the mounting plate 11 when the lifting plate 9 moves downward. The setting of the buffer 14 can reduce the impact of the lifting plate 9 on the mounting plate 11 when the lifting plate 9 moves downward, protect the mounting plate 11 from damage, increase the service life of the entire mechanism, and improve the stability of operation.

[0038] This core shaft grasping and rotating mechanism can automatically grasp and rotate the seat belt core shaft 2, reducing manual operation, reducing operational risks, and improving production efficiency and product quality stability. It can effectively adapt to the needs of large-scale production, reduce labor costs, and enhance the overall competitiveness of the production line.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
