Description

Technical Field

[0001] This utility model relates to the field of reciprocating screw technology, specifically a novel composite pitch reciprocating screw. 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 the reciprocating lead screw is in use, it does not have the function of damping the crescent guide block. As a result, the crescent guide block is prone to damage after long-term use, causing it to become unusable. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel composite pitch reciprocating screw that has the advantage of providing shock absorption for the crescent-shaped guide block, thus solving the problem that reciprocating screws do not have the function of providing shock absorption for the crescent-shaped guide block.

[0005] This utility model discloses a novel composite pitch reciprocating screw, comprising a reciprocating screw body. Both sides of the reciprocating screw body surface are fitted with damping components. Each damping component includes a fixed ring, the inner cavity of which is fixedly connected to the reciprocating screw body. Dampers are evenly spaced on the inner side of the fixed ring, and damping rings are located inside the dampers. Damping springs are fitted on the surface of the dampers, and both ends of the damping springs are fixedly connected to the connection points of the fixed ring and the damping rings by welding. Four movable holes are evenly spaced within the inner cavity of the fixed ring. A sliding rod is movably fitted within the inner cavity of each movable hole. A limiting block is provided on the outer side of the sliding rod, and the surface of the limiting block is movably connected to the movable hole. The inner side of the sliding rod is fixedly connected to the damping ring. When the crescent guide block needs to function as a shock absorber, it first contacts the shock absorber ring when it moves to the turning point of the reciprocating screw body. The shock absorber ring then transmits the impact force generated during the movement of the crescent guide block to the damper and the shock absorber spring. The damper and the shock absorber spring can reduce the impact force. The limit block and slide rod in the movable hole on the fixed ring can cooperate with the shock absorber ring to move. In this way, the shock absorber ring is more effective in transmitting impact force, thereby effectively reducing the impact force on the crescent guide block. This avoids the situation where the reciprocating screw body does not have the function of shock absorption for the crescent guide block, which would easily lead to damage to the crescent guide block after long-term use, causing the crescent guide block to be unable to function properly.

[0006] The present invention relates to a novel composite pitch reciprocating screw, wherein the inner cavity of the damping ring is movably connected to the main body of the reciprocating screw, and the diameter of the damping ring is the same as the diameter of the main body of the reciprocating screw.

[0007] This invention relates to a novel composite pitch reciprocating screw, wherein the inner side of the damping ring is provided with a rubber pad, and the outer side of the rubber pad is fixedly connected to the damping ring by an adhesive. Through the rubber pad, this invention can protect the crescent guide block when it comes into contact with the damping ring, thus preventing the crescent guide block from being easily damaged when it is in contact with the damping ring for a long time.

[0008] The present invention relates to a novel composite pitch reciprocating screw, wherein the outer side of the slide rod is fixedly connected to the limiting block by welding, and the outer side of the slide rod is located at the center of the inner side of the limiting block.

[0009] This utility model discloses a novel composite pitch reciprocating screw, wherein the reciprocating screw body is composed of a base layer, a NiCrAlY transition layer, and a WC-based wear-resistant coating. The NiCrAlY transition layer is located on the surface of the base layer, and the WC-based wear-resistant coating is located on the surface of the NiCrAlY transition layer. Through the cooperation of the NiCrAlY transition layer and the WC-based wear-resistant coating, the reciprocating screw body can be made wear-resistant during use, avoiding the situation where the reciprocating screw body will suffer severe wear and become unusable after long-term use.

[0010] The novel composite pitch reciprocating screw of this invention has a thickness of 200-280μm for both the NiCrAlY transition layer and the WC-based wear-resistant coating.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. When the crescent guide block needs to provide shock absorption, the crescent guide block will first contact the shock-absorbing ring when it moves to the turning point of the reciprocating screw body. The shock-absorbing ring will then transmit the impact force generated when the crescent guide block moves to the damper and the shock-absorbing spring. The damper and the shock-absorbing spring can reduce the impact force. The limiting block and sliding rod in the movable hole on the fixed ring can cooperate with the shock-absorbing ring to move. In this way, the shock-absorbing ring is more effective in transmitting impact force, thereby effectively reducing the impact force on the crescent guide block. This avoids the situation where the reciprocating screw body does not have the function of shock absorption for the crescent guide block, which would easily lead to damage to the crescent guide block after long-term use, causing the crescent guide block to be unable to function properly.

[0013] 2. This utility model uses a rubber pad to protect the crescent-shaped guide block when it comes into contact with the shock-absorbing ring, thus preventing damage to the crescent-shaped guide block that may occur if it is in contact with the shock-absorbing ring for a long time.

[0014] By combining the NiCrAlY transition layer and the WC-based wear-resistant coating, the reciprocating screw body can be made wear-resistant during use, thus preventing the reciprocating screw body from becoming severely worn and unable to function properly after long-term use.

[0021] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0022] Please see Figure 1-4This utility model discloses a novel composite pitch reciprocating screw, comprising a reciprocating screw body 1. Both sides of the surface of the reciprocating screw body 1 are fitted with damping components 2. Each damping component 2 includes a fixing ring 201, the inner cavity of which is fixedly connected to the reciprocating screw body 1. Damperes 203 are evenly spaced on the inner side of the fixing ring 201, and damping rings 205 are provided on the inner side of the dampers 203. Damper springs 202 are fitted on the surface of the dampers 203, and both ends of the damping springs 202 are fixedly connected to the connection points of the fixing ring 201 and the damping rings 205 by welding. Four movable holes 207 are evenly spaced within the inner cavity of the fixing ring 201. A sliding rod 206 is movably fitted within the inner cavity of each movable hole 207. A limiting block 208 is provided on the outer side of the sliding rod 206, and the surface of the limiting block 208 is movably connected to the movable holes 207. The inner side of the sliding rod 206 is fixedly connected to the damping rings 205. In this invention, when the crescent guide block needs to provide shock absorption, it first contacts the damping ring 205 when it moves to the turning point of the reciprocating screw body 1. The damping ring 205 transmits the impact force generated when the crescent guide block moves to the damper 203 and the damping spring 202. The damper 203 and the damping spring 202 can reduce the impact force. The limiting block 208 and the slide rod 206 in the movable hole 207 on the fixed ring 201 can move in conjunction with the damping ring 205. In this way, the damping ring 205 is more effective in transmitting impact force, thereby effectively reducing the impact force on the crescent guide block. This avoids the situation where the reciprocating screw body 1 does not have the function of damping the crescent guide block, which would easily lead to damage to the crescent guide block during long-term use and cause it to be unusable.

[0023] The inner cavity of the damping ring 205 is movably connected to the reciprocating screw body 1, and the diameter of the damping ring 205 is the same as the diameter of the reciprocating screw body 1.

[0024] The inner side of the shock-absorbing ring 205 is provided with a rubber pad 204, and the outer side of the rubber pad 204 is fixedly connected to the shock-absorbing ring 205 by an adhesive. With the rubber pad 204, the present invention can protect the crescent guide block when it comes into contact with the shock-absorbing ring 205, thus avoiding the crescent guide block from being easily damaged when it comes into contact with the shock-absorbing ring 205 for a long time.

[0025] The outer side of the slide rod 206 is fixedly connected to the limiting block 208 by welding, and the outer side of the slide rod 206 is located at the center of the inner side of the limiting block 208.

[0026] The reciprocating screw body 1 is composed of a base layer 101, a NiCrAlY transition layer 102, and a WC-based wear-resistant coating 103. The NiCrAlY transition layer 102 is located on the surface of the base layer 101, and the WC-based wear-resistant coating 103 is located on the surface of the NiCrAlY transition layer 102. Through the cooperation of the NiCrAlY transition layer 102 and the WC-based wear-resistant coating 103, the reciprocating screw body 1 can be made wear-resistant during use, thus avoiding the situation where the reciprocating screw body 1 is severely worn after long-term use, which would lead to the reciprocating screw body 1 being unable to be used normally.

[0027] The thickness of both the NiCrAlY transition layer 102 and the WC-based wear-resistant coating 103 is 200-280 μm.

[0028] When using this utility model: When the crescent guide block needs to play a shock-absorbing role, firstly, when the crescent guide block moves to the turning point of the reciprocating screw body 1, the crescent guide block will contact the shock-absorbing ring 205. The shock-absorbing ring 205 will transmit the impact force generated when the crescent guide block moves to the damper 203 and the shock-absorbing spring 202. The damper 203 and the shock-absorbing spring 202 can reduce the impact force. The limiting block 208 and the slide rod 206 in the movable hole 207 on the fixed ring 201 can cooperate with the shock-absorbing ring 205 to move. In this way, the shock-absorbing ring 205 has a better effect in transmitting impact force, thereby effectively reducing the impact force of the crescent guide block. This avoids the situation where the reciprocating screw body 1 does not have a shock-absorbing function for the crescent guide block, which would easily lead to damage to the crescent guide block during long-term use, causing the crescent guide block to be unable to be used normally.

[0029] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
