[0045] See also Figure 3 and Figure 4 The screw locking machine includes a locking device for completing the locking of the screws. Specifically, the locking device includes at least two screw-in parts 1 and a screw clamping mouth 2.

[0046] The plurality of screw-in members 1 are arranged at intervals along the first horizontal direction, and a screwdriver head 11 is provided at the end of each screw-in member 1 , and the screwdriver head 11 can complete the locking of the screw as the screw-in member 1 is screwed in.

[0047] The screw clamp 2 can be selectively located below one of the screw-in components 1 , and the screwdriver head 11 of the screw-in component 1 located above the screw clamp 2 can move in the vertical direction and achieve the locking of the screw in the screw clamp 2 .

[0048] The screw locking machine provided in this embodiment is equipped with multiple screw-in parts 1. The screwdriver heads 11 of different screw-in parts 1 can realize the locking of screws with different torques. A screw clamp 2 is selectively matched with one of the screw-in parts 1, so that one screw locking machine can complete the locking of screws with different torques, thereby improving the adaptability of the product.

[0049] Specifically, in this embodiment, the locking device includes two screw-in members 1. The screw clamping mouth 2 is also connected to a feeding pipe 5, and the feeder feeds the screw into the screw clamping mouth 2 through the feeding pipe 5.

[0050] Furthermore, in this embodiment, the locking device also includes a mounting plate, and the screw-in member 1 and the screw clamp 2 are both arranged on the mounting plate.

[0051] Specifically, the mounting plate includes a horizontal guide plate 31, a screw clamp fixing plate 32 and a vertical guide plate 33. The screw clamp fixing plate 32 is slidably arranged on the horizontal guide plate 31, the screw clamp 2 is arranged on the screw clamp fixing plate 32, and the screw clamp fixing plate 32 can move relative to the horizontal guide plate 31 along a first horizontal direction.

[0053] Furthermore, in order to enable the screw nozzle fixing plate 32 to move along the first horizontal direction and to be selectively located below one of the screwdriver heads 11, a second driving device 321 is provided at one end of the screw nozzle fixing plate 32. The second driving device 321 is used to drive the screw nozzle fixing plate 32 to reciprocate along the first horizontal direction, thereby driving the screw nozzle 2 to move along the first horizontal direction and be located below one of the screwdriver heads 11. Specifically, in this embodiment, the second driving device 321 is a cylinder, which is fixedly arranged on the lower surface of the horizontal guide plate 31 and the push rod of the cylinder is connected to the screw nozzle fixing plate 32. The movement of the screw nozzle fixing plate 32 is achieved by the extension and retraction of the cylinder push rod, thereby enabling the screw nozzle 2 to be selectively located below one of the screwdriver heads 11.

[0054] Specifically, Figure 3Taking the shown orientation as an example, in this embodiment, the air cylinder is provided at the left end of the screw chuck fixing plate 32. When the air cylinder push rod extends, the screw chuck 2 is located below the screw bit 11 on the right side; when the air cylinder push rod retracts, the screw chuck 2 is located below the screw bit 11 on the left side. Specifically, the screwing member 1 further includes a power device 13, and the screw bit 11 is provided on the power device 13. The screw bit 11 is driven by the power device 13 to screw in to achieve the locking of the screw. Specifically, in this embodiment, the model of the power device 13 is SKD-B519LC19.

[0055] Further, in this embodiment, a pneumatic pressure regulating valve 14 cooperating with the air cylinder is provided on the screw locking machine, which is used to adjust the pressure of the screw electric screwdriver 11 on the screw when the air cylinder moves downward, so as to achieve the locking of screws with different torques.

[0056] Further, in this embodiment, a guiding through hole extending in the vertical direction is provided on the horizontal guiding plate 31, and the screw bit 11 can pass through the guiding through hole and enter the screw chuck 2. The setting of the guiding through hole can effectively ensure that the axis of the screw bit 11 coincides with the axis of the screw to be locked, thereby ensuring the effectiveness of the locking.

[0057] Specifically, in this embodiment, the horizontal guiding plate 31 is vertically provided at the lower end of the vertical guiding plate 33.

[0059] Specifically, in this embodiment, the screwing member fixing part 4 is in a "C" shape, including a first horizontal mounting plate 41, a vertical plate 42 and a second horizontal mounting plate 43 for mounting the power device 13 of the screwing member 1. The first horizontal mounting plate 41 and the second horizontal mounting plate 43 are arranged at opposite ends of the vertical plate 42 and extend in the same direction. An installation hole is provided on the second horizontal mounting plate 43, and an annular flange is provided on the power device 13. The outer diameter of the annular flange is larger than the diameter of the installation hole. Preferably, in this embodiment, the first horizontal mounting plate 41 adopts a hoop structure form, including a first half plate 411 and a second half plate 412 that can be joined together. Both the first half plate 411 and the second half plate 412 are provided with semicircular holes. After the two semicircular holes are joined together, a circular hole adapted to the circumference of the power device 13 of the screwing member 1 is formed.

[0060] When installing the screw-in member 1, first install the power device 13. The power device 13 is installed downward in the vertical direction into the mounting hole on the second horizontal mounting plate 43. The annular flange cannot pass through the mounting hole and is clamped on the second horizontal mounting plate 43. The power device 13 is partially clamped in the semicircular hole of the first half plate 411. Then the second half plate 412 is aligned and connected with the first half plate 411 to complete the installation of the power device 13 on the screw-in member fixing member 4. Subsequently, the screwdriver head 11 is installed on the power device 13.

[0061] Preferably, in this embodiment, the screw-in member fixing member 4 is provided with a first sliding block matched with the first guide rail 331 , and the guide rail and sliding block structure is adopted to reduce the friction resistance of the screw-in member fixing member 4 during the sliding process.

[0062] Furthermore, the locking device also includes a plurality of first driving devices 12, and the first driving devices 12 are arranged in a one-to-one correspondence with the screw-in member 1, and the first driving devices 12 are used to drive the corresponding screw-in member 1 to reciprocate in the vertical direction. Specifically, in this embodiment, the first driving devices 12 are arranged in a one-to-one correspondence with the screw-in member fixing member 4, and the first driving devices 12 are cylinders, and the cylinder push rods are connected to the screw-in member fixing member 4, and the screw-in member fixing member 4 is driven by the first driving devices 12 to reciprocate in the vertical direction, thereby realizing the reciprocating movement of the screw-in member 1 in the vertical direction.

[0063] Furthermore, in this embodiment, a plurality of electric screwdriver fixing plates 332 are fixed on the vertical guide plate 33. The electric screwdriver fixing plates 332 are arranged one by one corresponding to the screwdriver heads 11. Positioning holes 3321 are opened on the electric screwdriver fixing plates 332. The positioning holes 3321 are used to prevent axial displacement when the corresponding screwdriver heads 11 are fastened with screws.

[0064] Specifically, in this embodiment, the electric screwdriver fixing plate 332 is arranged on the vertical guide plate 33 and is located between the horizontal guide plate 31 and the screw-in member fixing member 4. A positioning hole 3321 adapted to the lower end of the power device 13 is opened on the electric screwdriver fixing plate 332. When the power device 13 moves downward under the drive of the first driving device 12 until the screwdriver head 11 moves to the working position, the lower end of the power device 13 is clamped in the positioning hole 3321. The positioning hole 3321 can prevent the power device 13 from vibrating and causing the axis of the screwdriver head 11 to deviate.

[0065] In order to realize the movement of the locking device in three-dimensional space, the locking of screws at various positions on the product can be completed by moving the locking device at any point in the three-dimensional space. In this embodiment, the locking device can reciprocate in the vertical direction, can reciprocate in the first horizontal direction, and can reciprocate in the second horizontal direction. The second horizontal direction is set at an angle to the first horizontal direction. Preferably, in this embodiment, the second horizontal direction is perpendicular to the first horizontal direction.

The first screw 61 rotates around its own axis to drive the first ball nut 62 to move in the vertical direction. The locking device is connected to the first ball nut 62 and moves in the vertical direction with the first ball nut 62.

[0068] Specifically, in this embodiment, the vertical guide plate 33 of the locking device is connected to the first ball nut 62 and can move along the vertical direction with the first ball nut 62, thereby driving the entire locking device to move in the vertical direction. Further, in this embodiment, a connecting portion 621 is fixed on the first ball nut 62, and the vertical guide plate 33 is installed on the connecting portion 621 by screws or bolts. Preferably, in this embodiment, a connecting portion 621 is provided on each side of the first ball nut 62 to ensure the stability of the connection between the locking device and the first ball nut 62.

[0069] Furthermore, in the present embodiment, the first ball screw mechanism also includes a fixed back plate 65, and the upper and lower ends of the fixed back plate 65 are provided with a first screw mounting portion 651, and the end of the first screw 61 is rotatably provided on the first screw mounting portion 651; in order to ensure the straightness of the connecting portion 621 sliding up and down, in the present embodiment, two second guide rails 652 are provided on the fixed back plate 65, and the second guide rails 652 extend in the vertical direction and are arranged one by one with the connecting portion 621, and each connecting portion 621 is provided with a second slider 6211 that slides with the second guide rail 652. The structural form of the guide rail slider can ensure the straightness of the connecting portion 621 sliding up and down, thereby ensuring the accuracy of the locking screws.

[0070] Further, in this embodiment, the vertical direction guide part 6 also includes a third driving device 63. Specifically, in this embodiment, the third driving device 63 is a rotary motor, which drives the first lead screw 61 to rotate around its own axis. In this embodiment, in order to reduce the overall height of the screw locking machine, the rotary motor is arranged behind the first lead screw 61 and the motor shaft extends vertically upward. Accordingly, the vertical direction guide part 6 is provided with a mounting platform 631 for placing and installing the third driving device 63. At the same time, in order to realize that the third driving device 63 drives the first lead screw 61 to rotate around its own axis, a first synchronous wheel 632 is fixedly sleeved on the output shaft of the third driving device 63, a second synchronous wheel 622 is fixedly sleeved on the upper end of the first lead screw 61, and a synchronous belt is sleeved between the first synchronous wheel 632 and the second synchronous wheel 622, so that the third driving device 63 can drive the first lead screw 61 to rotate around its own axis.
