Description

Technical Field

[0001] The utility model relates to the technical field of screw machines, in particular to a single-head double-station automatic screw locking machine. Background Art

[0002] A screw machine is a small machine that automatically locks screws. Its action structure can generally be divided into two parts: the feeding part and the electric screwdriver part. The feeding part is responsible for screening and providing screws, and the electric screwdriver part is responsible for taking out and locking the screws. The emergence of screw machines has not only improved work efficiency but also reduced the intensity of manual work.

[0003] At present, screw machines are mainly single-station and multi-station, among which double-station screw locking machines are the most commonly used. However, most of the double-station screw locking machines at this stage have parallel feeding and discharging mechanisms, which take up a large space. When switching between the two stations for material change, the positions are different, resulting in a large material change stroke. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a single-head double-station automatic screw locking machine with a simple structure and small space occupation.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A single-head double-station automatic screw locking machine includes a screw locking machine and a double-station material changing mechanism, the double-station material changing mechanism includes a mounting platform, a fixed translation mold base and a lifting translation mold base are provided on the mounting platform, molds are installed on the fixed translation mold base and the lifting translation mold base, the fixed translation mold base and the lifting translation mold base are both connected to a counter-moving mechanism, a first gear is provided on the lifting translation mold base, the first gear is meshed with a first rack for transmission, the first rack is slidably arranged on the lifting translation mold base, and the top is fixedly connected to the mold, the first gear is also coaxially connected with a second gear and a third gear, the second gear is meshed with a second rack arranged on the mounting platform for transmission, the third gear is meshed with a third rack arranged on the mounting platform through a transfer gear, one end of the second rack and the third rack extends outward, and the other end is located in the middle of the mounting platform.

[0007] In this way, the counter-moving mechanism drives the fixed translation mold base and the lifting and translation mold base to move in opposite directions, thereby realizing the switching of work stations. During this period, the fixed translation mold base and the mold on it are always at the same horizontal height and remain unchanged, and the mold on the lifting and translation mold base is lifted and lowered to make way. With the horizontal movement of the lifting and translation mold base, the second gear on it is alternately meshed with the second rack and the third gear and the third rack. The third gear, under the action of the intermediate wheel, makes the second gear and the third gear rotate in opposite directions. The unidirectional horizontal movement is transmitted to the first gear, which will form a forward and reverse effect, thereby driving the first rack and the mold to achieve the movement of descending and then rising, thereby making way. This solution can realize the switching of the two mold bases with a single power, and can achieve making way under the same single power. The material changing position is fixed, the material changing stroke is short, the space occupied is small, and the operation is convenient.

[0008] As an optimization, the counter-moving mechanism includes a rotating belt arranged on the mounting platform, the rotating belt is transmission-connected to the driving motor, and the fixed translation mold base and the lifting translation mold base are respectively fixedly connected to the two side edges of the rotating belt.

[0009] In this way, the driving motor drives the rotary belt to realize forward and reverse rotation, and the fixed translation mold base and the lifting translation mold base on it realize horizontal movement in forward and reverse directions along with the rotary belt, thereby realizing station switching.

[0010] As an optimization, the fixed translation mold base and the lifting translation mold base are both fixedly connected to the mounting platform via linear guide rails.

[0011] In this way, the stable operation of the fixed translation mold base and the lifting translation mold base can be guaranteed, and the smooth switching of workstations can be guaranteed.

[0012] As an optimization, a guide rod is slidingly provided on the lifting and translating mold base, the top end of the guide rod is fixedly connected to the mold, and the bottom end is fixedly connected via a connecting rod.

[0013] In this way, during the lifting and lowering process of the mold to make way, the smooth operation of the mold is guaranteed to avoid neutralization and deviation.

[0014] As an optimization, the second rack and the third rack are spaced apart in the translation direction.

[0015] In this way, the second gear and the third gear are guaranteed to give way during the alternating meshing process, avoiding collision and ensuring smooth lifting.

[0016] This solution has the advantages of simple structure, small space occupation, and single power to achieve workstation switching and giving way. BRIEF DESCRIPTION OF THE DRAWINGS
