Technical Field

[0001] This utility model relates to the field of combination screw machine technology, specifically a multi-station synchronous fastening combination screw machine. Background Technology

[0002] A combination screw machine is a device used for the automatic or semi-automatic assembly, washer insertion, combination, and packaging of fasteners such as screws and nuts. Combination screw machines are widely used in various industries, including electronics, home appliances, automobiles, machinery manufacturing, construction, and furniture.

[0003] A combination screwdriver typically consists of a frame, a motion mechanism, a clamp, an electric screwdriver, and a torque sensor. The motion mechanism is responsible for the X, Y, and Z axis movements of the machine; the clamp is used to hold the workpiece and the screw; the electric screwdriver tightens the screw; and the torque sensor detects the tightening torque.

[0004] Regarding the above technical conditions, there is also the drawback that combination screw machines are usually equipped with one electric screwdriver to fasten screws to the workpiece, but when the workpiece requires multiple screws, the efficiency of fastening screws to the workpiece with one electric screwdriver is relatively low.

[0005] Based on this, this utility model designs a multi-station synchronous fastening combination screw machine to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a multi-station synchronous fastening combination screw machine to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-station synchronous fastening combination screw machine, comprising a frame, a motion structure, and an electric screwdriver. The motion structure is mounted on the frame, and the electric screwdriver is mounted on the motion structure. An operating table is mounted on the frame, and a positioning component is mounted on the operating table. The motion structure includes a linear motor, a slide rail, and a cylinder. Two linear motors are mounted on the frame, and each linear motor has a fixed frame for its moving block. The slide rail is mounted on the fixed frame, and two drive structures are slidably mounted on the slide rail. The cylinder is mounted on the drive structure, and the electric screwdriver is mounted on the cylinder, above the positioning component. Magnets are mounted on the drive structures, and the magnets on the two drive structures are arranged opposite each other.

[0008] Preferably, the operating table is provided with a material box, and two material boxes are mirror-arranged on the operating table, with the positioning component located between the two material boxes.

[0009] Preferably, a limiting groove is provided on the operating table, and a limiting block is fixedly provided on the material box, with the limiting block inserted into the limiting groove.

[0010] Preferably, the magnets on the two drive structures are of the same order.

[0011] Preferably, the positioning component includes a positioning block, a positioning groove, and an auxiliary groove. The positioning block is disposed on the operating table, the positioning groove is disposed on the positioning block, the auxiliary groove is disposed on the positioning block, and the auxiliary groove communicates with the positioning groove.

[0012] In summary, this application has the following beneficial technical effects: During use, the workpiece requiring screws is placed in the positioning slot of the positioning block. The positioning slot positions the workpiece. First, the drive structure is activated, causing the cylinder and electric screwdriver to move towards the material box. Then, the cylinder is activated again, causing the electric screwdriver to move downwards and remove the screws from the material box. Subsequently, the linear motor and drive structure are simultaneously activated, moving the electric screwdriver above the workpiece. The cylinder is activated again, causing the electric screwdriver to approach the workpiece and screw it onto it. Because there are two drive structures and two electric screwdrivers, two screws can be screwed onto the workpiece at once, improving screw-screwing efficiency and achieving the effect of improving the efficiency of screwing workpieces.

[0020] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] A multi-station synchronous fastening combination screw machine includes a frame 7, a motion structure, and an electric screwdriver 1. The motion structure is mounted on the frame 7, and the electric screwdriver 1 is mounted on the motion structure. An operating table 5 is mounted on the frame 7, and a positioning component is mounted on the operating table 5. The motion structure includes a linear motor 3, a slide rail 12, and a cylinder 10. Two linear motors 3 are mounted on the frame 7, mirror-image arranged on the frame 7. The moving blocks of the linear motors 3 are mounted on fixed frames 2, and the slide rail 12 is mounted on the fixed frames 2.

[0023] Two drive structures 11 are slidably mounted on the slide rail 12, and a cylinder 10 is mounted on the drive structure 11. An electric screwdriver 1 is mounted on the cylinder 10 and is located above the positioning component. Magnets 13 are mounted on the drive structures 11 and are positioned opposite each other. A material box 4 is mounted on the operating table 5, and two material boxes 4 are mirror images of each other on the operating table 5. The positioning component is located between the two material boxes 4. The material boxes 4 are used to hold screws.

[0024] The workpiece requiring screws is placed on the positioning assembly, which positions the workpiece. The linear motor 3 and drive structure 11 are activated, causing the cylinder 10 and electric screwdriver 1 to move left and right on the slide rail 12. The two drive structures 11 move in opposite directions. Under the action of the slide rail 12 and the cylinder 10, the electric screwdriver 1 transports the screws from the material box 4 to above the workpiece and screws them onto it.

[0025] A limiting groove 15 is provided on the operating table 5, and a limiting block 14 is fixedly installed on the material box 4. The limiting block 14 is inserted into the limiting groove 15. The setting of the limiting block 14 and the limiting groove 15 allows the material box 4 to be detachably installed on the operating table 5, making it convenient to remove the material box 4 from the operating table 5 to replace the screws.

[0026] The magnets 13 on the two drive structures 11 are of the same level. Magnets of the same level repel each other. When the two drive structures 11 move closer to each other, the magnets 13 of the same level can buffer the movement speed of the two drive structures 11, making it less likely for the two drive structures 11 to collide.

[0027] The positioning assembly includes a positioning block 8, a positioning groove 9, and an auxiliary groove 6. The positioning block 8 is mounted on the operating table 5, the positioning groove 9 is mounted on the positioning block 8, and the auxiliary groove 6 is mounted on the positioning block 8, communicating with the positioning groove 9. The positioning groove 9 positions the workpiece, and the auxiliary groove 6 allows the workpiece to be easily removed from the positioning groove 9.

[0028] The implementation principle of this embodiment is as follows: In use, the workpiece that needs to be screwed is placed in the positioning groove 9 of the positioning block 8. The positioning groove 9 positions the workpiece. First, the drive structure 11 is activated, which moves the cylinder 10 and the electric screwdriver 1 towards the material box 4. Then, the cylinder 10 is activated, and the electric screwdriver 1 moves down to take out the screw from the material box 4. After that, the linear motor 3 and the drive structure 11 are activated simultaneously, and the electric screwdriver 1 is moved above the workpiece. The cylinder 10 is activated again, and the electric screwdriver 1 moves closer to the workpiece and screws it onto the workpiece. Since there are two drive structures 11 and two electric screwdrivers 1, two screws can be screwed onto the workpiece at one time, which improves the screw-screwing efficiency and achieves the effect of improving the efficiency of screwing the workpiece.
