Description

Technical Field

[0001] This utility model relates to the field of reciprocating lead screw processing technology, specifically a positioning mechanism for reciprocating lead screw processing. Background Technology

[0002] A reciprocating lead screw is a type of lead screw that enables a slider to reciprocate without changing the direction of rotation of the main shaft. It is commonly used in the mechanical field and is used in conjunction with a motor.

[0003] When machining reciprocating lead screws, a positioning mechanism is required to position them. However, the positioning mechanism is not capable of fixing reciprocating lead screws of different diameters, thus requiring the replacement of different models of positioning mechanisms to fix the reciprocating lead screws, which leads to a decrease in the machining efficiency of the reciprocating lead screws. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a positioning mechanism for processing reciprocating lead screws, which has the advantages of fixing reciprocating lead screws of different diameters, and solves the problem that positioning mechanisms cannot fix reciprocating lead screws of different diameters.

[0005] This utility model discloses a positioning mechanism for reciprocating lead screw processing, comprising a base. Two sides of the top of the base are provided with spacing adjustment components. Each spacing adjustment component includes a connecting plate, the bottom of which is fixedly connected to the base. Two sides of the top of the connecting plate are provided with sliding rods. Two sides of the surface of each sliding rod are fixedly fitted with fixing plates, the bottoms of which are fixedly connected to the base. Two sides of the surfaces of the two sliding rods are movably fitted with movable plates. The top of each movable plate is provided with a placement wheel. Both ends of the top of the connecting plate are provided with electric push rods, the output ends of which are fixedly connected to the movable plates. Two sides of the top of the base are provided with positioning components. Each positioning component includes an L-plate located outside the connecting plate, the bottom of which is fixedly connected to the base. The top of the L-plate is provided with a cylinder, the output end of which extends through and to... The bottom of the L-plate is equipped with a pressure plate. When positioning reciprocating lead screws of different diameters is required, the electric push rod first runs, then drives the moving plate inward. The moving plate moves in conjunction with the sliding rod, and the moving plate drives the placement wheels to move. After the placement wheels move to the required position, the electric push rod stops running. At this time, the reciprocating lead screw is placed on the two placement wheels. Then, the cylinder runs, driving the pressure plate downward. When the pressure plate contacts the reciprocating lead screw, the reciprocating lead screw is fixed by the cooperation of the placement wheels and the pressure plate. This makes fixing reciprocating lead screws of different diameters more convenient and avoids the situation where the positioning mechanism is not capable of fixing reciprocating lead screws of different diameters, thus requiring the replacement of different models of positioning mechanisms to fix the reciprocating lead screws, which leads to a decrease in the processing efficiency of the reciprocating lead screws.

[0006] The positioning mechanism for reciprocating lead screw processing of this utility model includes a limiting plate fixedly sleeved on both sides of the surface of the electric push rod, and the bottom of the limiting plate is fixedly connected to the connecting plate. The limiting plate can fix the electric push rod, thus improving the performance of the electric push rod during use and avoiding shaking during use, which would lead to unstable operation of the electric push rod.

[0007] The positioning mechanism for reciprocating lead screw processing of this utility model includes an anti-slip sleeve on the surface of the placement wheel, and the anti-slip sleeve has anti-slip threads on its surface. The anti-slip sleeve can prevent the reciprocating lead screw from slipping on the placement wheel when it is placed on the placement wheel, thus avoiding the situation where the reciprocating lead screw has poor positioning effect.

[0008] The positioning mechanism for reciprocating lead screw processing of this utility model, wherein the two ends of the outer side of the L plate are fixedly connected to the base by support frames, and the two support frames are arranged symmetrically about the center of the L plate. The support frames can fix the L plate, so that the L plate is more effective in use and avoids the L plate from moving during use, which would lead to the instability of the components on the L plate.

[0009] The positioning mechanism for reciprocating lead screw processing of this utility model includes a rubber pad at the bottom of the pressure plate, and the top of the rubber pad is fixedly connected to the pressure plate by an adhesive. The rubber pad can protect the reciprocating lead screw when the pressure plate positions it, thus preventing damage to the reciprocating lead screw during positioning.

[0010] The positioning mechanism for reciprocating lead screw processing of this utility model has mounting plates fixedly connected to both ends of the base, and the inner cavity of the mounting plate is provided with mounting holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When positioning reciprocating lead screws of different diameters, this utility model first operates an electric push rod, which then drives a moving plate to move inward. The moving plate moves via a sliding rod, which in turn moves the placement wheels. Once the placement wheels reach the desired position, the electric push rod stops. The reciprocating lead screw is then placed on the two placement wheels. Next, a cylinder operates, driving a pressure plate downward. When the pressure plate contacts the reciprocating lead screw, the placement wheels and pressure plate work together to fix the lead screw. This method makes fixing reciprocating lead screws of different diameters more convenient, avoiding the situation where the positioning mechanism is incapable of fixing reciprocating lead screws of different diameters, necessitating the replacement of different models of positioning mechanisms and reducing the processing efficiency of the reciprocating lead screws.

[0012] 2. This utility model uses a limiting plate to fix the electric push rod, which makes the electric push rod perform better during use and avoids shaking during use, thus preventing the electric push rod from becoming unstable. The support frame can fix the L-plate, which makes the L-plate perform better during use and prevents the L-plate from moving during use, thus preventing the components on the L-plate from becoming unstable. The anti-slip sleeve can prevent the reciprocating screw from slipping on the placement wheel when it is placed on the placement wheel, thus avoiding the situation where the reciprocating screw slips on the placement wheel and thus the reciprocating screw positioning effect is poor. The rubber pad protects the reciprocating screw when the pressure plate positions it, preventing damage to the screw during this process. Attached Figure Description

The bottom of the L-plate 201 is fixedly connected to the base 1. The top of the L-plate 201 is provided with a cylinder 202, and the output end of the cylinder 202 extends through and to... The bottom of L-plate 201 is equipped with a pressure plate 203. When positioning reciprocating lead screws of different diameters is required, the electric push rod 304 first runs, then drives the moving plate 302 to move inward. The sliding rod 303 moves in conjunction with the moving plate 302, and the moving plate 302 drives the placement wheel 306 to move. After the placement wheel 306 moves to the required position, the electric push rod 304 stops running. At this time, the reciprocating lead screw is placed on the two placement wheels 306. Then, the cylinder 202 runs, driving the pressure plate 203 to move downward. When the pressure plate 203 contacts the reciprocating lead screw, the placement wheel 306 and the pressure plate 203 can cooperate to fix the reciprocating lead screw. This makes fixing reciprocating lead screws of different diameters more convenient and avoids the situation where the positioning mechanism is not capable of fixing reciprocating lead screws of different diameters, thus requiring the replacement of different models of positioning mechanisms to fix the reciprocating lead screws, which leads to a decrease in the processing efficiency of the reciprocating lead screw.

The limiting plate 305 can fix the electric push rod 304, so that the electric push rod 304 performs better when used and avoids the electric push rod 304 from shaking during use, which would lead to the unstable operation of the electric push rod 304.

[0018] The surface of the placement wheel 306 is fitted with an anti-slip sleeve, and the surface of the anti-slip sleeve is provided with anti-slip threads. The anti-slip sleeve can prevent the reciprocating screw from slipping on the placement wheel 306 when it is placed on the placement wheel 306, thus avoiding the situation where the reciprocating screw has poor positioning effect.

[0019] Both ends of the outer side of L-plate 201 are fixedly connected to the base 1 by support brackets 204. The two support brackets 204 are arranged symmetrically about L-plate 201. The support brackets 204 can fix L-plate 201, so that L-plate 201 is more effective in use and avoids L-plate 201 from moving during use, which would lead to instability of the components on L-plate 201.

[0020] The bottom of the pressure plate 203 is provided with a rubber pad, and the top of the rubber pad is fixedly connected to the pressure plate 203 by adhesive.

[0022] When using this invention: When positioning reciprocating lead screws of different diameters is required, firstly, the electric push rod 304 operates, then the electric push rod 304 drives the moving plate 302 to move inward, and the sliding rod 303 cooperates with the moving plate 302 to move, and the moving plate 302 drives the placement wheel 306 to move. After the placement wheel 306 moves to the required position, the electric push rod 304 stops operating. At this time, the reciprocating lead screw is placed on the two placement wheels 306, and then the cylinder 202 operates, driving the pressure plate 203 to move downward. When the pressure plate 203 contacts the reciprocating lead screw, the reciprocating lead screw can be fixed by the cooperation of the placement wheel 306 and the pressure plate 203. This makes fixing reciprocating lead screws of different diameters more convenient, avoiding the situation where the positioning mechanism is not capable of fixing reciprocating lead screws of different diameters, thus requiring the replacement of different models of positioning mechanisms to fix the reciprocating lead screws, resulting in a decrease in the processing efficiency of the reciprocating lead screw.
