Description

Technical Field

[0001] The utility model relates to a buffer type walking positioner component, belonging to the technical field of positioners. Background Art

[0002] In traditional walking positioners, rigid hard-connected positioner structures are usually used for loading and unloading workpieces. This structure has some problems during long-term use, mainly including the following points. First, the rigid connection leads to the accumulation of axis deviation: due to the rigid connection of the positioner, the axis deviation caused by installation error and workpiece error will accumulate on the positioner. With the increase of use time, this rigid deviation may cause damage to mechanical components, especially uneven force on the drive motor. Second, the impact of vibration and impact affects stability: during the walking process of the positioner, vibration and impact may have a negative impact on the stability of the system. These unstable factors may cause additional displacement of the workpiece, affecting the operating accuracy and equipment life. Third, rigid deviation causes structural deformation: due to the limitations of the rigid connection structure, the positioner is prone to additional force when loading and unloading workpieces, resulting in structural deformation, which affects its long-term stability and maintainability. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a buffer type walking positioner assembly, which can avoid structural deformation caused by axis deviation accumulation and rigidity deviation, and ensure stability under vibration and impact.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A buffered walking positioner assembly comprises a positioner, a walking base and a driving component, wherein the driving component is arranged on the walking base, the positioner is installed on the driving component, and the driving component drives the positioner to move forward and backward on the walking base, the driving component comprises a base plate, a motor driving component is arranged on the base plate, and buffer components are respectively arranged on the front and rear directions of the left and right sides of the base plate, the buffer component comprises a fixed plate, the fixed plate is connected to the side surface of the base plate, a connecting rod is passed through the fixed plate along the front and rear direction, an adjustment block is sleeved on the inner side of the connecting rod, a damper is sleeved on the outer side of the connecting rod, stop parts are arranged at both ends of the connecting rod, and the four corners of the lower end of the positioner are respectively correspondingly inserted into the connecting rod between the adjustment block and the fixed plate.

[0006] The connecting rod is a bolt, the head of the bolt faces outwards, and an adjusting nut is sleeved on the inner end of the bolt.

[0007] The motor drive assembly cooperates with the rack on the walking base through a driving gear.

[0008] The material of the damper includes rubber or metal.

[0009] The fixing plate is L-shaped.

[0010] The connecting rod is sleeved with a gasket located between the nut and the adjusting block.

[0011] Beneficial effects of the utility model: The utility model provides a buffer-type walking positioner assembly, in which buffer assemblies are respectively arranged in the front and rear directions of the left and right sides of the bottom plate of the driving component, and the four corners of the lower end of the positioner are respectively correspondingly inserted into the connecting rod between the adjustment block and the fixed plate in the driving component, so that the positioner can be more stable during walking and loading and unloading of workpieces, avoiding the problems that may be caused by traditional rigid connection structures. The setting of the buffer assembly can absorb the axial displacement generated when the positioner is flipped, and can disperse vibrations and impacts, ensuring the reliability of the entire system and stability in long-term use. Through the synergistic effect of the buffer assemblies at all four sides, the system is subjected to more stable and uniform force, which improves the accuracy and stability of loading and unloading workpieces.
