Technical Field

[0001] The invention belongs to the technical field of automatic processing equipment, and in particular relates to an automatic single-batch screw locking device. Background Art

[0002] With the development of social sciences, the level of mechanical automation technology is getting higher and higher. Screws are currently the most widely used fasteners in products in the electronic assembly, hardware accessories, automobile and other industries. As the structure of products becomes more and more complex, there are more and more screws on a single product, and the total amount of products is also increasing. Therefore, if the screw tightening operation is performed manually, the production efficiency will be extremely low.

[0003] At present, although there are some automatic screw tightening equipment on the market, there are still some problems: 1. It can only tighten flat workpieces; 2. If the first screw is not locked, the second screw in the queue must be removed before the third screw can be tightened, which reduces work efficiency and increases work costs; 3. The position to be tightened is on the side wall, which makes operation inconvenient; 4. There are obstructions on the side of the screw hole, which makes operation inconvenient and makes it impossible to tighten the screw. Summary of the invention

[0004] The present invention aims to solve the above-mentioned defects and provides an automatic single batch screw locking device.

[0005] In order to overcome the defects in the background technology, the technical solution adopted by the present invention to solve the technical problem is: an automatic single batch screw locking device, including a driving device, a cylinder body is sleeved on the driving device, an air hole is arranged at the lower part of the cylinder body, and a guide column is movably arranged in the cylinder body;

[0007] A plurality of slots are arranged at the lower end of the guide column, and the top of a nozzle head is movably arranged in each slot; the nozzle heads cooperate to form a thread outlet, and the thread outlet is in a funnel structure;

[0008] An anti-deflection cylinder is sleeved on the lower part of the driving device, the lower part of the anti-deflection cylinder is arranged in the guide column, and the bottom end of the anti-deflection cylinder is arranged above the wire inlet; a plurality of openings are arranged at the bottom of the anti-deflection cylinder, and a spring is sleeved on the anti-deflection cylinder, one end of the spring is fixed on the driving device, and the other end is fixed on the bottom inner wall of the guide column.

[0009] In a preferred embodiment of the present invention, the driving device is an electric screwdriver or a pneumatic screwdriver.

[0010] In a preferred embodiment of the present invention, the air hole is arranged below the end of the guide column.

[0011] In a preferred embodiment of the present invention, the wire inlet cooperates with the wire feeding nozzle.

[0012] In a preferred embodiment of the present invention, there are two card slots, which are arranged on the left and right sides of the guide column.

[0013] In a preferred embodiment of the present invention, the top of the nozzle clamp head is an arc-shaped structure, which cooperates with the slot, and the top of the nozzle clamp head can roll left and right in the slot.

[0014] In a preferred embodiment of the present invention, a protrusion extending downward is provided at the bottom end of the guide column to cooperate with the nozzle head.

[0015] In a preferred embodiment of the present invention, a gap is left between the anti-deflection cylinder and the guide column.

[0016] In a preferred embodiment of the present invention, there are two openings, which are symmetrical front to back, and arc-shaped grooves are provided at the tops of the openings.

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention has a simple structure, is easy to operate, and improves production efficiency;

[0019] 2. Due to the elastic design of the bottom of the anti-deflection cylinder, it can not only adapt to flat workpieces, but also be suitable for locking countersunk screws;

[0020] 3. Due to the design of the clamping head, when the first screw is not tightened, it will automatically fall off and then tighten the second one without disassembly, which improves production efficiency and saves time cost;

[0021] 4. Since the top of the screw can be clamped on the bottom of the anti-deflection cylinder, when the screw is installed on the side wall, the screw will not fall off and cannot be installed, which facilitates the operation of personnel and improves work efficiency;

[0022] 5. Due to the movable setting of the guide column, when there is an obstruction on the side of the screw hole, the screw will not be unable to be tightened, which can be suitable for screw tightening work in different environments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0030] like Figure 1 and Figure 2 As shown, a single batch screw locking device comprises an air screwdriver 1, the upper part of which is sleeved with a cylinder body 2, an air hole 2.1 is arranged on one side of the lower end of the cylinder body 2, a guide column 3 is movably arranged in the cylinder body 2, and the air hole 2.1 is arranged below the end of the guide column 3, so that air intake of the air hole can lift up the guide column; a thread inlet 3.1 is arranged at the lower part of the guide column 3, a thread inlet nozzle 4 is clamped on the thread inlet 3.1, and the thread inlet 3.1 cooperates with the thread inlet nozzle 4 to facilitate screw feeding; two card slots 3.2 are arranged at the lower end of the guide column 3, and the two card slots 3.2 are respectively arranged on the left and right sides of the guide column 3, and the top of the clamping head 5 is movably clamped in each card slot 3.2, and the top of the clamping head 5 is an arc-shaped structure, which cooperates with the card slot 3.2, and the top of the clamping head 5 can roll left and right in the card slot 3.2 to prevent the screw from bouncing; the two clamps The nozzle head 3.2 cooperates to form a thread outlet 6, and the thread outlet 6 has a funnel structure, which is convenient for the top of the screw to be stuck; the bottom end of the guide column 3 is provided with a downwardly extending protrusion 3.3, which cooperates with the clamping nozzle head to prevent the screw from popping out and causing unnecessary damage; the lower part of the air screwdriver 1 is provided with an anti-deflection cylinder 7, the lower part of the anti-deflection cylinder 7 is arranged in the guide column 3, and a gap is left between the inner wall of the guide column 3, and the bottom end of the anti-deflection cylinder 7 is arranged above the thread inlet 3.1, which is convenient for feeding the screw; the bottom of the anti-deflection cylinder 7 is provided with two front-to-back symmetrical openings 7.1, and the upper end of the opening 7.1 is provided with an arc-shaped groove 7.2, which plays a role of limiting and preventing the screw from deflecting; the anti-deflection cylinder 7 is provided with a spring 8, one end of the spring 8 is fixed on the air screwdriver 1, and the other end is fixed on the inner step 3.4 at the bottom of the guide column 3, which plays a role of resetting the anti-deflection cylinder.

[0031] The working principle of the present invention is as follows: a screw is blown into the guide column from the thread inlet nozzle, and the screw quickly slides to the funnel-shaped thread outlet between the clamping nozzle heads; the air screwdriver is started, air is taken in through the air inlet hole, the airflow pushes the guide column upward, the spring is compressed, and the anti-deflection cylinder moves downward relative to the guide column. Since the bottom of the anti-deflection cylinder is provided with an elastic opening, the top of the screw is first clamped into the anti-deflection cylinder and contacts the screwdriver head. Since the guide column moves upward, the anti-deflection cylinder moves downward relatively, and the clamping nozzle head is pushed outward to prop it up to prevent the screw from bouncing, thereby realizing the locking of the screw; the air screwdriver is stopped, and due to the elasticity of the spring, the guide column automatically returns to the initial position under the push of the spring, thereby completing a cycle.
