Description

Technical Field

[0001] The utility model relates to the field of assembly equipment, in particular to a positioning and flipping fixture of an automatic screw locking machine. Background Art

[0002] At present, when products on the market are assembled from various parts, screws are usually used to lock and reinforce the parts. Traditional screw locking operations generally use manual operations. Operators use screwdrivers to tighten the screws of each component one by one to assemble them into the product to be produced. In order to improve work efficiency, people have developed automatic screw locking machines.

[0003] A Chinese utility model patent with authorization announcement number CN203901724U discloses a fully automatic nut implanting equipment, which includes a machine head, a vibration disk mechanism, a Z-axis machine head motion mechanism, a fixture mounting platform, a frame, a control panel, an X-axis motion mechanism, a Y1-axis motion mechanism, and a Y2-axis motion mechanism; the machine head is arranged above the frame, the vibration disk mechanism is connected to the machine head, a Z-axis machine head motion mechanism is provided on the machine head, an X-axis motion mechanism is provided below the machine head, and Y1-axis motion mechanisms and Y2-axis motion mechanisms are symmetrically provided below the X-axis motion mechanism. A control panel is provided on the side wall of the frame, and a fixture mounting platform is provided above the control panel, and the fixture mounting platform is provided on the guide rails of the Y1-axis motion mechanism and the Y2-axis motion mechanism, which improves production efficiency, can meet the diversity of nuts of multiple sizes and products, and saves machine adjustment time.

[0004] However, the positions of the screw holes on the workpiece may not be on the same horizontal plane, and the fixture mounting platform of the above-mentioned nut implanting device can only be translated and cannot be flipped forward and backward, so there are relatively large restrictions when locking the nut. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a positioning and flipping fixture for an automatic screw locking machine, which has the advantages of solving the problems raised in the above background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] The cam is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate

[0008] By adopting the above technical solution, during operation, the operator places the workpiece on the upper surface of the fixed plate, and at this time cooperates with the clamping assembly to clamp and limit the two sides of the workpiece to prevent deviation from affecting the operation. Then the operator starts the rotating motor forward or reverse according to the operation requirements, and drives the rotating shaft to rotate forward or reverse through the coupling, and then the mounting plate on the rotating shaft rotates, which can drive the fixed plate between the mounting plates to rotate forward or reverse until the workpiece on the mounting plate is flipped to the appropriate working area surface, saving workpiece operation time and improving work efficiency.

[0009] It is further configured that a reinforcement ring is fixedly connected between the outer side of the rotating shaft and the mounting plate.

[0010] By adopting the above technical solution, the reinforcement ring provided between the rotating shaft and the mounting plate plays a supporting and stabilizing role, thereby ensuring the stability of the mounting plate and other components between the mounting plates when they rotate in coordination.

[0011] Further arrangement: the clamping assembly includes a fixing seat arranged on both sides of the limit groove, and a positive and negative screw rod is rotatably connected between the fixing seats, one end of the positive and negative screw rod extends to the outside of the clamping groove, and the extended end of the positive and negative screw rod is connected to a servo motor through a coupling, and a first clamping block and a second clamping block are matched and connected to the outside of the positive and negative screw rod, the bottom of the first clamping block and the second clamping block are both slidably matched with the clamping groove, the top of the first clamping block and the second clamping block are both extended to the outside of the clamping groove, and the adjacent side of the extended end of the first clamping block and the second clamping block is fixedly connected with an anti-slip pad.

[0012] By adopting the above technical solution, during operation, the operator places the workpiece on the upper surface of the fixed plate. At this time, the operator starts the servo motor according to the length requirement of the workpiece to drive the forward and reverse screws to rotate. At this time, the first clamping block and the second clamping block on the forward and reverse screws cooperate with the clamping groove to move toward each other until the anti-slip pads on the adjacent side of the first clamping block and the second clamping block contact both sides of the workpiece, thereby increasing the friction force and clamping and protecting the workpiece.

[0013] Further configuration: the upper surface of the fixing plate is provided with staggered anti-slip textures.

[0014] By adopting the above technical solution, during operation, the operator places the workpiece on the upper surface of the fixed plate. At this time, the bottom of the workpiece contacts the anti-slip texture provided on the upper surface of the fixed plate, thereby increasing friction and playing an anti-slip role.

[0015] Further configuration: a baffle is provided above the rotating motor.

[0016] By adopting the above technical solution, the rotating motor is exposed to the air during operation, which will generate a certain amount of dust. The setting of the baffle can play a certain role in blocking the dust and also play a protective role.

[0017] It is further configured that a reinforcing plate is fixedly connected to the bottom of the fixing plate.

[0018] By adopting the above technical solution, the provision of the reinforcing plate plays a supporting and stabilizing role for the fixed plate, thereby ensuring the bearing capacity of the fixed plate.

[0019] In summary, the present invention has the following beneficial effects:

[0020] The utility model is equipped with a clamping assembly. During operation, the operator places the workpiece on the upper surface of the fixed plate. At this time, the operator starts the servo motor according to the length requirement of the workpiece to drive the forward and reverse screw rods to rotate. At this time, the first clamping block and the second clamping block on the forward and reverse screw rods cooperate with the clamping groove to move toward each other until the anti-slip pads on the adjacent sides of the first clamping block and the second clamping block contact with both sides of the workpiece, thereby increasing the friction force and clamping and protecting the workpiece.

[0021] In the present invention, when the workpiece is clamped and fixed in conjunction with other components, the operator starts the rotating motor in the forward or reverse direction according to the work requirements, and drives the rotating shaft to rotate in the forward or reverse direction through the coupling, thereby rotating the mounting plate on the rotating shaft, thereby driving the fixed plate between the mounting plates to rotate in the forward or reverse direction until the workpiece on the mounting plate is flipped to a suitable working area surface, saving workpiece operation time and improving work efficiency.
