TECHNICAL FIELD

[0001] The utility model relates to automatic equipment technical field, in particular to a full -automatic multi -shaft screw locking device. BACKGROUND

[0002] In modern manufacturing industry, screw fastening is an important link in product assembly process. The traditional screw fastening mode depends on manual operation, which is not only inefficient, but also prone to quality problems such as screw fastening not firm and torque inconsistency. With the expansion of production scale and the improvement of product quality requirements, there is an urgent need for a screw locking equipment with high automation degree and good stability.

[0003] Some screw locking equipment on the market can realize automation to a certain extent, but there are still deficiencies in positioning accuracy, screw locking efficiency and adaptability to different products. For example, some equipment cannot accurately position the product in all directions, resulting in screw locking position deviation. Or when facing different specifications of products, frequent replacement of jigs or complex adjustment is required, which affects production efficiency. Therefore, it has important practical significance to develop a full-automatic multi-axis screw locking device that can solve the above problems. SUMMARY

Transport device is used to carry carrying jig and make it move within a certain range, to provide basic platform for subsequent operation. Carrying jig is used to place the product to be locked screw, and moves with the transport device. Screw vibration feeding device is responsible for orderly conveying screw to the specified position, so that screw locking device can be used. Screw locking device can move on transport device, realize accurately locking screw on product. Positioning device can also be movably arranged on transport device, and is fixed to product in all directions, to ensure the accuracy of screw locking. Compression device can be close to or away from screw locking device, and is fixed to product on carrying jig in vertical direction, to prevent product displacement during screw locking.

[0006] Further, the screw locking device includes horizontal moving assembly, lifting assembly, spacing adjustment assembly and locking assembly.

[0007] Horizontal moving assembly: the horizontal moving assembly of the screw locking device is a lead screw transmission mechanism. The rotation of the lead screw drives the nut to move, thereby realizing the accurate movement of the entire screw locking device in the horizontal direction. The output end of the horizontal moving assembly is connected to the lifting assembly, providing the basis for the horizontal movement of the lifting assembly.

[0008] The lifting assembly also adopts a lead screw transmission mechanism and works cooperatively with the horizontal moving assembly. The lead screw of the lifting assembly rotates under the drive of the motor, causing the nut to drive the spacing adjustment assembly and subsequent components installed at the output end to move up and down in the vertical direction, so as to adjust the height between the screw locking device and the product, and adapt to the screw locking needs of products of different heights.

[0009] The spacing adjustment assembly includes a spacing adjustment base, a drive motor, an adjustment lead screw, etc. The spacing adjustment base is fixed to the output end of the horizontal moving assembly and serves to support and fix other components.

[0014] Third positioning mechanism: including a third positioning table which can be lifted and inserted on the conveying device, and a lifting and moving structure driven by a third lifting cylinder. The third positioning table is arrayed with T-shaped positioning rods on one side. When the third lifting cylinder drives the third positioning table to rise, the T-shaped positioning rods can be inserted into the specific position of the product, positioning the product from another direction, realizing the all-round positioning and fixing of the product, and ensuring that the product will not shift during the screw locking process.

[0015] Further, the pressing device includes a pressing cylinder fixed to the conveying device and a pressing plate fixed to the output end of the pressing cylinder. When the product is positioned by the positioning device, the pressing cylinder acts to push the pressing plate downward, pressing and fixing the product on the carrying jig in the vertical direction, so that the product remains stable during the screw locking process, avoiding the product position deviation caused by vibration or other external forces, thereby ensuring the quality of screw locking.

[0016] Further, the screw vibration feeding device includes a vibration disc feeder; a horizontal moving assembly is arranged above the output end of the vibration disc feeder; a screw clamping and lifting cylinder is arranged at the output end of the horizontal moving assembly; and screw gripping finger cylinders are arrayed at the output end of the screw clamping and lifting cylinder.

[0017] Vibration disc feeder: as the core component of the screw vibration feeding device, it orderly arranges and conveys the disordered screws to the output end through vibration. The internal structure of the vibration disc feeder is designed ingeniously, which can make the screws gradually arrange into neat queues under the action of vibration, facilitating subsequent grabbing and conveying.

[0018] Horizontal moving assembly: arranged above the output end of the vibration disc feeder, which moves the screw clamping and lifting cylinder and subsequent components to the appropriate position in the horizontal direction to grab the screws output by the vibration disc feeder. The horizontal moving assembly also adopts a lead screw transmission mechanism or other suitable transmission mode to realize accurate horizontal displacement control.

[0019] Screw clamping and lifting cylinder: installed at the output end of the horizontal moving assembly, which can move up and down in the vertical direction. When the horizontal moving assembly moves it to the screw grabbing position, the screw clamping and lifting cylinder descends, so that the screw gripping finger cylinder below can contact the screw.
