Description

Technical Field

[0001] The invention is applied to the technical field of material transport tracks, and particularly relates to a lifting and bidirectional width-adjusting mechanism. Background Art

[0002] With the advancement of science and technology, industrial automation has been widely used. Most of the products with complex structures are assembled through assembly lines. For parts with different specifications that need to be transported, if multiple conveying tracks that are compatible with the parts are set up, it is obviously not in line with modern concepts and increases equipment costs. If the conveying track is set as a large track, it seems to be overkill for large parts, which will also increase equipment costs. If the conveying track is set as a small track, large parts cannot be accurately positioned. However, most of the track lines in today's automated production are bundled with side guards and belt lines. The belt line on one side is fixed, and the track line on the other side is movable to adapt to the size of various products. Moreover, it is impossible to directly transfer the products from the fixed module to the track line. The transfer can only be achieved by adding additional mechanisms. The buffering of the belt line is also achieved by dividing the belt line into three sections. Such a track line is not only complex in structure and high in equipment cost, but also cumbersome in operation, which is not conducive to improving work efficiency. Therefore, it is necessary to provide a lifting and bidirectional width adjustment mechanism with a simple structure, easy operation and blocking positioning. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a lifting bidirectional width-adjusting mechanism which has a simple structure, is easy to operate and can achieve blocking positioning.

[0004] The technical solution adopted by the present invention is: the present invention includes a track line module, a width adjustment module and a lifting module, the width adjustment module includes a screw and a width adjustment structure, the width adjustment structure includes a ball nut, a connecting block, a first fixed block and a rib, the ball nut passes through the connecting block and is fixed on the outside of the connecting block, one end of the screw passes through the ball nut and the first fixed block in sequence, the rib is fixedly arranged on the connecting block and is parallel to the transportation direction of the track line module, a handle is arranged at the end of the screw, the number of the width adjustment structure is two groups, the two groups of the width adjustment structures are respectively arranged at both ends of the screw and are located on both sides of the transportation direction of the track line module, the lifting module includes a first lifting cylinder, a lifting block and a lifting plate, the lifting block is transmission-connected to the first lifting cylinder, the first lifting cylinder realizes lifting and lowering action on the lifting plate through the lifting block, and two first fixed blocks are respectively fixed at both ends of the lifting plate.

[0005] It can be seen from the above scheme that the width adjustment module is arranged on both sides of the transport direction of the track line module, and the width adjustment module can limit and fix the material on the track line module. The lifting module is arranged at the lower end of the width adjustment module, and the lifting module can realize the lifting action of the material on the track line module to meet the needs of transferring the material to different height positions. The width adjustment module includes a ball screw, and the ball screw has the characteristics of small friction loss and high transmission efficiency. This is because there are many balls rolling between the screw and the ball nut. The ball screw converts the rotational motion into linear motion. When the handle is turned, the ball nut will be converted into linear motion with the rotation angle of the screw. The connecting block moves back and forth on the screw in a straight line, thereby realizing the action of the retaining edge clamping the material. The two groups of the width adjustment structures are respectively arranged at the two ends of the screw to perform bidirectional limit and fixation on both sides of the material. The width adjustment module can be used for materials of different specifications for limit and fixation, which fully reflects the flexibility and adaptability of the width adjustment module.

[0006] A preferred solution is that the width adjustment module also includes a bearing, and the inner side of the first fixed block is provided with a countersunk hole compatible with the bearing, the bearing is arranged in the countersunk hole, the screw passes through the ball nut, the bearing and the first fixed block in sequence, and the end of the screw is threadedly connected to the handle.

[0007] It can be seen from the above solution that the bearing can be used to support the screw rod and reduce the friction coefficient of the screw rod rotation. The handle can smoothly rotate the screw rod, thereby improving work efficiency.

[0008] A preferred solution is that the width adjustment module also includes two guide pillars and a guide sleeve, the two guide pillars are respectively arranged in parallel on both sides of the screw, the guide sleeve passes through the connecting block and is fixed on the outside of the connecting block, and one end of the guide pillar passes through the guide sleeve and is fixedly connected to the first fixed block.

[0009] It can be seen from the above scheme that the guide column passes through the connecting block and is fixedly connected to the first fixed block. When the connecting block makes a linear reciprocating motion on the screw, the connecting block also makes a synchronous linear motion on the guide column and the screw. The guide column is used to ensure the stability of the width adjustment module, and the guide sleeve can reduce the friction of the guide column on the connecting block.

[0010] A preferred solution is that the width adjustment module further includes a locking structure, which is fixedly arranged on the outer side of the first fixing block and cooperates with the screw rod to limit the position.

[0011] It can be seen from the above solution that the locking structure can be used to limit and fix the screw rod, so as to prevent the screw rod from loosening during the material transportation process, thereby preventing the material from being unable to be clamped.

[0012] A preferred solution is that the track line module includes two groups of belt conveyor lines, and the two groups of belt conveyor lines are fixed at equal distances on the jacking plate and located on the inner sides of the two retaining edges.

[0013] It can be seen from the above scheme that the two groups of belt conveyor lines serve as conveyor lines for materials. The two groups of belt conveyor lines are equidistantly arranged and fixed on the lifting plate and located on the inner side of the two guardrails. The two groups of belt conveyor lines cooperate with the width adjustment module to move so that the material remains in the center position on the two groups of belt conveyor lines to prevent the material from shifting during the movement.

[0014] A preferred solution is that the lifting block includes a protrusion, a threaded shaft and a nut, the protrusion is fixedly set at one end of the threaded shaft, the nut is adapted to the threaded shaft and sleeved on the threaded shaft, the other end of the threaded shaft is connected to the first lifting cylinder, and the lifting plate is provided with a through hole adapted to the protrusion, a U-shaped protrusion is fixedly set at one end of the inner side of the through hole, the inner side of the U-shaped protrusion is adapted to the threaded shaft, the opening of the U-shaped protrusion forms a circular hole with the through hole, and the circular hole is adapted to the threaded shaft.

[0015] It can be seen from the above scheme that the protrusion passes through the circular hole and moves onto the U-shaped protrusion. The fixing of the lifting block to the lifting plate is achieved by tightening the nut. The other end of the threaded shaft is transmission-connected to the first lifting cylinder, thereby completing the lifting and lowering movement of the material by the lifting module. When there is no need to lift the material, the nut can be loosened, and the lifting block can be moved to the circular hole position and taken out. The setting of the lifting block and the through hole facilitates the loading and unloading of the lifting module, thereby ensuring the stability of the lifting two-way width adjustment mechanism during the lifting process.

[0016] A preferred solution is that the lifting bidirectional width adjustment mechanism also includes a blocking module, which includes a first block, a second lifting cylinder and a second fixed block. The second fixed block is fixedly arranged on one side of the retaining edge, and the second lifting cylinder is slidably matched with the inner side of the second fixed block. The first block is fixedly arranged on the second lifting cylinder and is transmission-matched with the second lifting cylinder, and the orientation direction of the first block is consistent with the incoming direction of the track line module.

[0017] It can be seen from the above scheme that the second lifting cylinder cooperates with the first stopper in transmission, and the second lifting cylinder controls the lifting and lowering of the first stopper, thereby stopping the material on the track line module and proceeding to the next process.

[0018] A preferred solution is that the number of the blocking modules is four, and the four blocking modules are respectively arranged at two ends of the two retaining edges.

[0019] It can be seen from the above scheme that the four groups of blocking modules are respectively arranged at the two ends of the two retaining edges, which can be used to buffer the materials at the input and output ends of the track line module, reflecting the flexibility of the jacking bidirectional width adjustment mechanism.

[0020] A preferred solution is that the lifting bidirectional width adjustment mechanism also includes a positioning module, the positioning module includes a telescopic cylinder, a third fixed block and a third lifting cylinder, the telescopic cylinder is fixedly arranged on one side of the rib through the third fixed block, the third lifting cylinder is fixedly arranged at the action end of the telescopic cylinder, the telescopic cylinder is transmitted in a horizontal direction, the positioning module also includes a groove block and two second blocks, the third lifting cylinder is transmission-connected to the groove block, and the two second blocks are slidably fitted on the groove block and point to the inner side of the rib.

[0021] It can be seen from the above scheme that the telescopic cylinder can realize horizontal movement of the second stop block, and the third lifting cylinder can realize vertical movement of the second stop block. The coordinated activities of the telescopic cylinder and the third lifting cylinder can adapt to the adjustment and limit of materials of different specifications. The positioning module can adjust and limit the material on the track line module in the horizontal direction to maintain the correct position of the material on the track line module, so as to facilitate moving to the next workstation for precise positioning.

[0022] A preferred solution is that the number of the positioning modules is four, and the four positioning modules are respectively arranged at both ends of the two retaining edges.

[0023] It can be seen from the above scheme that the four groups of positioning modules are respectively arranged at the two ends of the two retaining edges. The four groups of positioning modules can adjust and limit the materials on the track line module in the horizontal direction, thereby maintaining the correct position of the materials on the track line module, making it easy to move to the next workstation for precise positioning.
