Description

Active connecting rod spinner

technical field

The utility model relates to a mounting fixture for a spiral motion pair, in particular to a movable connecting rod spinning machine.

Background technique

In industrial production, the helical motion pair is one of the most common basic structures, especially in enterprises related to automobile manufacturing, the helical pair is almost a must. A typical one is a double-ended screw, with nuts that rotate left and right on both sides. This kind of screw must be pre-installed before being installed on the equipment. The nut and the double-ended screw are screwed together, and the two ends rotate about 100 times together. . In the traditional process, it is generally purely manual operation, or only a simple clamp is used to fix the screw, and the nut is screwed in by manual twisting. Because most of these workpieces are made of steel, the size is relatively large, and the weight is mostly about 15-20 kilograms, the labor intensity is very large. Moreover, in production, workers have to repeat operations many times, which is inefficient, and even some workpieces require two people to operate at the same time. Therefore, there is a great need for an auxiliary installation device for screw motion pairs that is easy to operate and can improve efficiency.

Those of ordinary skill in the art can understand the specific meanings of the above terms in the present utility model in specific situations.

Referring to Figures 1-3, a movable connecting rod spinning machine includes a frame 1, on which the first and second rollers 33, 34 are arranged, and a pressure roller 35 is arranged above the first and second rollers, The wheel shaft 17 of the pressure roller is installed on the pressure roller mounting seat 6, and the pressure roller mounting seat 6 is connected to the floating joint 12 of the vertical cylinder 11. The first and second rollers are driven by the belt transmission mechanism to rotate in the same direction. The connecting rod is clamped and rotated by the pinch wheel and the pressure roller; chute 42 is respectively set on both sides of the first and second rollers, and the connecting rod nut (not shown) is set in the chute, and the tail end of the chute is connected to the horizontal cylinder 45, so that The horizontal cylinder pushes the chute to screw the connecting rod nut on the connecting rod.

The upper side frame 3 is set on the frame 1, and the chute and the horizontal cylinder are installed on the upper side frame 3. A cylinder mounting plate 5 is arranged on the top of the frame 1, and the vertical cylinder 11 is mounted on the cylinder mounting plate 5, and a down-pressing guide rod 9 is connected between the cylinder mounting plate 5 and the pressure wheel mounting seat 6. The first and second rollers are connected on the same motor shaft pulley 25 by a V-belt 37 . The first and second rollers and the pinch wheel are all made up of a rubber wheel 14 and a steel wheel 16, and the rubber wheel is arranged on the outer surface of the steel wheel.

In order to make the operation easier and more convenient, reduce labor intensity and improve efficiency, the utility model adopts a triangular-distributed roller mechanism, which is different from the common three-star roller structure. Compared with the structure of the conventional three-star roller, the utility model has different rotation directions firstly. The three-star roller is often a driving roller, and the other rollers are meshed by gears, and the rotation direction is opposite. The roller position of this mechanism is strictly controlled by processing. The control is determined and cannot be adjusted after installation, including the transmission clearance is also basically determined, so there is no opening and closing space, and loading and unloading cannot be performed. The mechanism of the utility model is driven by a motor shared by two belts to realize the same rotation direction. The other roller is driven and can be moved or compressed under the independent drive of the cylinder. When moving away, there is enough space to take out or put in the workpiece. When working, press the workpiece while rotating the workpiece, screw in the nuts on both sides, and the center is automatically determined. Therefore, the structure is adjustable in terms of the direction of rotation and the space between the rollers, and has better flexibility.

In addition, in order to protect the surface of the workpiece and generate reliable friction, the surface of the roller should be wrapped with a soft material, which is more suitable for polyurethane after analysis. When this material is used, it is generally coated on the metal surface through a special encapsulation technology, and the two are bonded together through high temperature, and sometimes a special mold is made for the required shape. For non-standard equipment, there are not many identical parts, so the cost of mold opening is too high. Even simple lagging does not conform to economic principles due to the small amount. Therefore, in this design, the rubber layer of the rubberized roller is formed by processing the bar. In the process of processing, the problem of difficult clamping of soft rubber is overcome by adding steel parts in the middle. Structurally, the method of screw side pressure installation is used to solve the problem that the lagging is easy to peel off. These methods provide a favorable reference for the use of non-metallic materials after machining and forming.

Although the embodiments of the present invention have been shown and described, those skilled in the art should understand that various changes, modifications, substitutions and Variations, the scope of the utility model is defined by the claims and their equivalent replacements, and improvements made without creative work should be included in the protection scope of the utility model.
