A screw-inserting machine

Abstract

This utility model discloses a screw-wafer insertion machine, including a column with an L-shaped structure. A motor is detachably connected to one end of the column's horizontal plate, and a turntable is detachably connected to the motor's output end. A screw is located on the bottom sidewall of the turntable near its edge. A guide plate is located below the turntable, with a sloping groove in the middle. Because the machine drives the screw to move and actively insert it into the corresponding washer, the washer moves along with the screw. As the screw moves, it brings the washer with it. With increasing pressure, the washer is passively fitted into the screw. The pressure applied to the washer gradually increases with movement, finally pushing the washer out from between the two vertical columns, completing the washer insertion operation. Because the screw is horizontally positioned, the washer is prevented from falling off after being fitted, eliminating the need for a nut for reinforcement. This simplifies the entire device, reduces operational steps, and improves operational convenience.

Description

Technical Field

[0001] This utility model relates to the technical field of screw threading machines, specifically to a screw threading machine. Background Technology

[0002] A screw is a type of fastener that typically works with a nut or threaded groove to secure and lock a target object. To improve the stability of tightening a screw, a washer is usually placed on it, which increases the reliability of the screw after it is tightened.

[0003] Currently, screw manufacturers place washers on the screws during the manufacturing process, then tighten the corresponding nuts, and finally package them together for shipment. This reduces the probability of missing parts. To improve efficiency, washer insertion machines are usually used. However, current washer insertion machines slide the washer to the corresponding position and then lift the washer to insert it into the screw. This method requires tightening the nuts at the same time, making the equipment operation cumbersome. Therefore, a screw washer insertion machine is proposed here. Utility Model Content

[0004] The technical problem this utility model aims to solve is that current screw threading machines involve sliding the washer to the corresponding position and then lifting the washer to fit into the screw. This method requires tightening the nut at the same time, making the operation of the equipment cumbersome. This invention provides a screw threading machine that can actively insert the screw into the corresponding washer. Because it is an active insertion, it does not require the nut to be tightened simultaneously, reducing the cumbersomeness of the equipment and improving the convenience of operation.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a screw threading machine, including a column, the column having an L-shaped structure, a motor being detachably connected to one end of the horizontal plate of the column, a turntable being detachably connected to the output end of the motor, a screw being provided on the bottom side wall of the turntable near the edge, a guide plate being provided below the turntable, a groove being provided in the middle of the guide plate, the groove having an inclined structure, and a feed box being fixedly connected to the top side wall of the groove near one end.

[0006] As a preferred technical solution of this utility model, the bottom of the turntable and the side wall near the edge are provided with mounting grooves at equal intervals, and an electric gripper is detachably connected in the mounting groove, the electric gripper holding the screw through its gripper.

[0007] As a preferred embodiment of this utility model, a gasket is slidably connected in the chute, and the gasket in the end of the guide plate away from the feed box corresponds to the screw. The screw is inserted into the corresponding gasket. A feed groove is provided on the top of the feed box, and an inclined guide plate is fixed in the feed groove.

[0008] As a preferred embodiment of this utility model, one end of the guide plate extending into the feed box corresponds to the slide groove, the gasket slides down the inclined surface of the guide plate into the slide groove, and two support columns are detachably connected to the bottom side wall of the guide plate.

[0009] As a preferred technical solution of this utility model, a discharge conveyor belt is provided directly below the turntable, a rubber pad is fixed on the surface wall of the discharge conveyor belt, a protective plate is fixed on the end of the guide plate away from the feed box, and two vertical columns are fixed on the side wall of the guide plate near the protective plate, with the vertical columns corresponding to the two side edges of the pad.

[0010] As a preferred technical solution of this utility model, a bottom groove is provided in the middle of the bottom side wall of the guide plate, and a conveyor belt is rotatably connected in the bottom groove. The surface of the conveyor belt is provided with a pair of grooves, and a baffle is fixedly connected in each groove. The two corresponding baffles are distributed in a V-shaped structure.

[0011] This invention has the following advantages: Because it drives the screw to move and actively inserts the screw into the corresponding washer, the washer moves along with the screw. As the screw moves, the washer comes into contact with the vertical column. As the pressure increases, the washer is passively fitted into the screw. The pressure applied to the washer gradually increases with the movement, and finally the washer is pushed out from between the two vertical columns to complete the washer insertion operation. Because the screw is horizontal, it can prevent the washer from falling off after being fitted. Therefore, there is no need to use a nut for reinforcement, which simplifies the entire device, reduces the operation process, and improves the convenience of operation. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 This utility model discloses a screw threading machine, including a column 1, which has an L-shaped structure. One end of the horizontal plate of the column 1 is detachably connected to a motor 2. The output end of the motor 2 is detachably connected to a turntable 3. A screw 13 is provided on the bottom side wall of the turntable 3 near the edge. A guide plate 4 is provided below the turntable 3. A chute 5 is provided in the middle of the guide plate 4. The chute 5 has an inclined structure. A feed box 6 is fixedly connected to the top side wall of the chute 5 near one end.

[0018] The bottom of the turntable 3 and the side wall near the edge are provided with mounting grooves 11 at equal intervals. An electric gripper 12 is detachably connected in the mounting groove 11. The electric gripper 12 clamps the screw 13 through its gripper. A gasket 8 is slidably connected in the slide 5. The gasket 8 in the end of the guide plate 4 away from the feed box 6 corresponds to the screw 13. The screw 13 is inserted into the corresponding gasket 8. The top of the feed box 6 is provided with a feed groove, and an inclined guide plate 7 is fixed in the feed groove. The end of the guide plate 7 that extends into the feed box 6 corresponds to the slide 5. The gasket 8 slides down the inclined surface of the guide plate 7 into the slide 5. Two support columns 9 are detachably connected to the bottom side wall of the guide plate 4. A discharge conveyor belt 10 is set directly below the turntable 3. A rubber pad is fixed on the surface of the discharge conveyor belt 10.

[0019] The technical effect of this solution is as follows: The starting motor 2 drives the turntable 3 to rotate, which in turn drives the screw 13 to rotate. Because the washer 8 at one end of the guide plate 4 corresponds to the screw 13, the screw 13 moves and inserts into the corresponding washer 8. With the constraint of the vertical column 19, the washer 8 is passively fitted into the screw 13, completing the washer insertion process. After the foremost washer 8 is fitted, the conveyor belt 15 sends subsequent washer 8s to the foremost position, where they fit against the protective plate 18 and the vertical column 19, thus completing the design of the front end of the guide plate 4. The open structure avoids obstructing the movement of screw 13 and affecting the normal pad insertion process. After pad insertion is completed, screw 13 will move to the top of the discharge conveyor belt 10, and then the clamp on screw 13 will be released, allowing screw 13 to fall naturally onto the discharge conveyor belt 10. Because rubber pads are fixed on the surface of the discharge conveyor belt 10, screw 13 is prevented from bouncing off the discharge conveyor belt 10. Then the discharge conveyor belt 10 will send the pad-inserted screw 13 away, and then clamp and position the new screw 13 for the next round of pad insertion.

[0020] A protective plate 18 is fixed to one end of the guide plate 4 away from the feed box 6. Two vertical columns 19 are fixed to the side wall of the guide plate 4 near the protective plate 18, and the vertical columns 19 correspond to the two side edges of the gasket 8. A bottom groove 14 is opened in the middle of the bottom side wall of the guide plate 4. A conveyor belt 15 is rotatably connected in the bottom groove 14. A pair of grooves 16 are opened on the surface of the conveyor belt 15. A baffle 17 is fixedly connected in each groove 16. The two corresponding baffles 17 are distributed in a V-shape.

[0021] The technical effects of this solution are as follows: the conveyor belt 15 can actively transport the gaskets 8, and multiple pairs of grooves 16 on the conveyor belt 15 can position each gasket 8, thus enabling stable and continuous transport. In conjunction with the side wall of the guide plate 4, the gaskets 8 can be effectively constrained, ensuring that the gaskets 8 are in an upright state. The conveyor belt 15 is designed to be in a timed and controllable transport state, which facilitates continuous supply of gaskets 8, makes continuous gasket threading convenient, and improves processing efficiency. Since there is no need to tighten the screws 13, many parts can be reduced, simplifying the equipment and improving the convenience of operation.

[0022] Specifically, in use, the gasket 8 is placed into the guide plate 7 at the top of the feed box 6. The gasket 8 gradually moves downward along the inclined surface of the guide plate 7, finally passing through the top of the feed box 6 and entering the chute 5, landing between the two corresponding baffles 17, thus effectively confining the gasket 8. Then, the conveyor belt 15 is started to drive the gasket 8 to the end position, and the motor 2 is started to drive the turntable 3 to rotate, thereby driving the electric gripper 12 to rotate synchronously. This causes the screw 13, which is held by the electric gripper 12, to rotate along with it. As the screw 13 moves, it will insert into the corresponding gasket 8. With the help of the vertical column 19 to confine the gasket 8, from... The washer 8 is smoothly inserted into the screw 13, and the screw 13 with the washer inserted moves onto the discharge conveyor belt 10. Then the constraint on the screw 13 is released, and the screw 13 falls onto the discharge conveyor belt 10 and is finally sent away by the discharge conveyor belt 10. The freed-up electric gripper 12 clamps the new screw 13 for the next round of washer insertion. The new screw 13 can be fed manually or moved synchronously by the conveyor belt 15 and the electric gripper 12. In this way, the new screw 13 can be clamped during the movement, and the feeding can be achieved. Alternatively, the electric gripper 12 can be replaced with a gripping device such as an electric suction cup, depending on the actual situation.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
