[0097] In this embodiment, the screw rod accommodating unit 3 includes:

[0098] The screw electric cylinder 31 is arranged vertically upward;

[0099] The screw rod seat 32 is provided with a through groove for accommodating the screw rod 8 , and the groove is opposite to the rod head to accommodate the fixing unit 1 .

[0100] In this embodiment, the screw rod clamping and screwing unit 4 includes:

[0101] The horizontal sliding component 41 slides in a direction parallel to the axial direction of the screw rod 8 when it is screwed in; the reset control unit 5 is connected to the sliding end of the horizontal sliding component 41;

[0102] The hollow rotating seat 42 is rotatably disposed on the sliding end of the horizontal sliding assembly 41, and the axis thereof is parallel to the axial direction of the screw rod 8 when it is screwed in;

[0103] The driving motor 43 is arranged on the sliding end of the horizontal sliding assembly 41 and is connected to the rotating seat 42 by a belt, so as to drive the rotating seat 42 to rotate on the sliding end of the horizontal sliding assembly 41;

[0104] The clamping electric cylinder 44 is arranged at one end of the rotating seat 42 facing the screw rod accommodating unit 3; the axis of the clamping electric cylinder 44 is a hollow structure; the measuring end of the screw rod screwed into the measuring unit 6 passes through the rotating seat 42 and the clamping electric cylinder 44 to measure the end of the screw rod 8.

[0105] The rotating seat 42 is in the shape of a circular tube, and a tooth groove that can be connected to the belt is arranged on the outer surface, so that the driving motor 43 can drive the rotating seat 42 to rotate. At the same time, the clamping electric cylinder 44 is connected to the rotating seat 42 by a slewing ring, which not only achieves a stable connection, but also ensures that the clamping electric cylinder 44 can rotate synchronously with the rotating seat 42.

[0106] In this embodiment, the reset control unit 5 includes:

[0107] The reset electric cylinder 51 is disposed on one side of the horizontal sliding assembly 41 and is parallel to the horizontal sliding assembly 41 , and its telescopic end is connected to the sliding end of the horizontal sliding assembly 41 .

[0108] The reset electric cylinder 51 controls the clamping electric cylinder 44 to reset and complete the clamping and fixing of the screw rod 8 in the next assembly.

[0109] In this embodiment, the reset control unit 5 further includes:

[0110] A horizontal displacement sensor 52 is disposed on the fixed end of the horizontal sliding assembly 41, and a telescopic end thereof is connected to the sliding end of the horizontal sliding assembly 41;

[0111] The locking electric cylinder 53 is vertically downwardly arranged on the sliding end of the horizontal sliding assembly 41;

[0112] The locking column 54 is coaxially connected with the telescopic end of the locking electric cylinder 53;

[0113] The locking plate 55 is arranged on the telescopic end of the reset electric cylinder 51. The locking plate 55 is provided with a locking hole 551 facing the locking column 54. When the locking column 54 is located directly above the locking plate 55, the locking column 54 is inserted into the locking hole 551 under the control of the locking electric cylinder 53, so that the locking plate 55 and the locking column 54 are connected together.

[0114] In order to reduce the amount of parts that need to be driven when the screw rod 8 is screwed in and to avoid excessive force on the screw rod 8, the reset electric cylinder 51 is not driven synchronously during the screwing-in process of the screw rod 8. Therefore, the displacement of the clamping electric cylinder 44 is known through the horizontal displacement sensor 52, and then the reset electric cylinder 51 is controlled to move an equal amount, and then the locking column 54 is controlled to reset the clamping electric cylinder.

[0115] In this embodiment, the screw-in measuring unit 6 includes:

[0116] Measuring substrate 61;

[0117] The measuring sliding assembly 62 is arranged on the measuring substrate 61, and its sliding direction is parallel to the axis of the screw rod 8 when it is screwed in;

[0118] The measuring cylinder 63 is arranged on the measuring substrate 61, and the telescopic end is connected to the sliding end of the measuring sliding assembly 62;

[0119] The displacement measuring sensor 64 is arranged on the sliding end of the measuring sliding assembly 62, and its axis is colinear with the axis of the screw rod 8 when it is screwed in;

[0120] The measuring rod 65 has one end slidably disposed on the sliding end of the measuring sliding assembly 62 , and the other end passes through the hollow rotating seat 42 and is located in the clamping area of ​​the clamping electric cylinder 44 ; the diameter of the measuring rod 65 is smaller than the diameter of the screw rod 8 .

[0121] After the screw rod 8 is screwed in, the measuring cylinder 63 moves forward at a fixed value, driving the measuring rod 65 to retract after it abuts against the screw rod 8. The screw-in length of the screw rod 8 can be known by measuring the retraction amount. In this way, the screw-in amount of the screw rod 8 can be effectively measured to ensure that the screwed-in amount of the screw rod 8 meets the requirements.

[0122] The assembly riveting mechanism of the screw rod 8 in this embodiment works as follows: first, the rod head 7 is placed in the receiving groove 111 and positioned by the positioning column 112; then, one end of the screw rod 8 to be screwed in is inserted into the rod head 7 and abutted against the thread of the rod head 7, and the middle part is placed flat in the groove of the screw rod seat 32, thereby completing the placement of the rod head 7 and the screw rod 8.

[0123] The lifting cylinder 122 is controlled to shorten, driving the lifting plate 123 to descend, so that the pressing seat 13 connected to the lifting plate 123 moves downward to complete the mold closing with the accommodating seat 11 to completely fix the rod head 7.

[0124] The reset electric cylinder 51 is controlled to move, driving the clamping electric cylinder 44 to move until the end of the screw rod 8 is located in the clamping claw of the clamping electric cylinder 44, the reset electric cylinder 51 is stopped from moving, the clamping electric cylinder 44 is controlled to clamp and fix the screw rod 8, and then the locking electric cylinder 53 is controlled to shorten, and the locking column 54 is separated from the locking plate 55.

[0125] Start the drive motor 43, drive the rotating seat 42 and the clamping electric cylinder 44 to rotate, and finally rotate the screw rod 8. Since the end of the screw rod 8 is in a state of abutment with the rod head 7, the screw rod 8 rotates relative to the rod head 7, which will cause the screw rod 8 to be screwed into the rod head 7 along the thread.

[0126] When the rotating seat 42 rotates to a certain number of circles, it stops rotating. The control measuring cylinder 63 is extended to a predetermined value. During the extension process, the measuring rod 65 moves forward until it contacts the end surface of the screw rod 8, and then is forced to squeeze into the displacement measuring sensor 64. Finally, the displacement measuring sensor 64 (with an automatic reset function) obtains the displacement value, and determines whether the screw-in length of the screw rod 8 meets the standard according to the position value. If the screw-in amount does not meet the standard, the control measuring cylinder 63 is reset, so that the measuring rod 65 is also reset, and the number of clockwise or counterclockwise rotations of the screw rod 8 is calculated according to the screw-in amount, and the drive motor 43 is controlled to rotate the corresponding rotation amount, so that the amount of the screw retraction or screw-in is near the predetermined value, and then the measurement cylinder 63 is repeatedly extended to the predetermined value, and the screw-in amount of the screw rod 8 is measured until the screw-in amount of the screw rod meets the standard. The control measuring cylinder 63 is reset again.

[0127] After the screw rod 8 is screwed in to a certain amount, the stamping cylinder 22 is controlled to extend, and the stamping and riveting of the screw rod 8 and the rod head 7 by the riveting needle 14 is completed.

[0128] The reset electric cylinder 51 controls the locking plate 55 connected thereto to move to the position directly below the column according to the displacement data of the horizontal displacement sensor 52, and then controls the locking electric cylinder 53 to extend to complete the connection with the reset electric cylinder 51. Subsequently, the clamping electric cylinder 44 is controlled to release the clamping of the lead screw 8, and then the reset electric cylinder 51 is controlled to move to drive the clamping electric cylinder 44 to reset.

[0129] Finally, the lifting electric cylinder 122 is controlled to reset, and the screw rod 8 and the rod head 7 riveted together are taken out.

[0130] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
