Description

Technical Field

[0001] This invention belongs to the field of mechanical transmission equipment technology, and particularly relates to a mechanism capable of automatically reversing linear motion and a worktable integrating the mechanism. Background Technology

[0002] In automated production, linear reciprocating motion is a common motion requirement. The traditional way to achieve this linear reciprocating motion is to control the forward and reverse rotation of the drive motor. However, frequent switching of the drive motor's forward and reverse rotation will reduce the lifespan of the drive motor and increase the maintenance cost of the enterprise's equipment. In order to solve the above problems, a linear automatic reciprocating mechanism and worktable are designed. Summary of the Invention

[0003] The purpose of this invention is to control the alternating meshing of two active gears and two moving gears by the cooperation of the pusher and the push rod, so as to achieve the purpose of automatic linear reversal of the moving part without switching the forward and reverse rotation of the drive motor. This solves the problem in the above-mentioned background technology that frequent switching of the forward and reverse rotation of the drive motor will reduce the service life of the drive motor and increase the maintenance cost of enterprise equipment.

[0004] The specific technical solution of the present invention is as follows: A linear automatic reversing mechanism includes a base, a drive motor mounted on the base, a drive shaft of the drive motor connected to a drive gear, the drive gear meshing with a driven gear, a connecting shaft for each of the drive and driven gears, a drive face gear slidably connected to the front end of the connecting shaft, a support platform for the front end of the base, a shaft rotatably connected to the support platform, a driven face gear matching the drive face gear at the rear end of the shaft, a movable component slidably connected to the upper surface of the support platform, a drive gear on the shaft, and a rack matching the drive gear on the movable component, a fixed rod on the upper surface of the base, the fixed rod located between two drive face gears, a reversing component and an adjusting component rotatably connected to the fixed rod respectively, the reversing component and the adjusting component being tensioned by a tension spring, a pushing component connected to the rear surface of the movable component, a push rod matching the pushing component on the adjusting component, a limiting groove on the outer circumferential surface of the drive face gear, and limiting components matching the limiting groove rotatably connected to the left and right sides of the reversing component respectively.

[0005] Furthermore, the rear facade of the movable component is provided with a linear mounting groove, which is slidably connected to two pushers. The two pushers and the linear mounting groove are slidably and fixed relative to each other by a combination of bolts and nuts. The left and right sides of the adjusting component are respectively provided with push rods, which are located on the upper and lower surfaces of the adjusting component. The contact surface between the pushers and the push rods is an inclined surface.

[0006] Furthermore, the upper surface of the support platform is provided with a linear groove, and the lower surface of the moving part is provided with a slider that matches the linear groove.

[0007] Furthermore, the rear facade of the support platform is provided with shaft holes for use with the shaft rod.

[0008] Furthermore, the upper surface of the base is provided with limiting rods, with the two limiting rods located on the left and right sides of the adjusting component, respectively.

[0009] Furthermore, the rear end of the adjusting component is provided with a positioning hole for use with the fixing rod, the front end of the reversing component is provided with a sleeve for use with the fixing rod, the left and right sides of the sleeve are respectively provided with connecting parts, the connecting parts are provided with assembly holes, and the limiting component is provided with an assembly rod for use with the assembly holes.

[0010] Furthermore, the connecting member includes an upper connecting member and a lower connecting member, with the driving gear located between the upper connecting member and the lower connecting member.

[0011] Furthermore, the rear end of the base is provided with a mounting platform, and the mounting platform is provided with a connecting through hole for use with the connecting shaft.

[0012] Furthermore, the mounting platform has connecting ears on opposite sides, and a brake rod is rotatably connected between the two connecting ears. The outer circumference of the brake rod has a brake element, and the brake element has limiting wings on both sides. The brake element has a positioning groove in the middle that matches the reversing component, and an operating lever is provided on one side of the brake rod.

[0013] A workbench includes a table surface and the aforementioned linear automatic reversing mechanism, wherein the table surface and the moving part are detachably connected.

[0014] Compared with the prior art, the present invention has the following beneficial effects: When the linear reversing mechanism is running, the drive motor drives the driving gear to rotate, and the driving gear drives the driven gear to rotate. Since the driving gear and the driven gear mesh, their rotation directions are opposite. Because the reversing component and the adjusting component are connected by a tension spring, the reversing component will always be biased to one side. Through the cooperation of the limiting component and the limiting groove, the driving face gear on the biased side of the reversing component meshes with the driven face gear, while the other side is disengaged. The drive gear and the rack drive the moving component to move. As the moving component moves, the pushing component pushes the push rod, causing the adjusting component to change its deflection direction, thereby causing the moving component to perform linear reciprocating motion. The linear automatic reversing purpose of the moving component can be achieved without changing the forward and reverse rotation of the drive motor, avoiding frequent switching of the drive motor's forward and reverse rotation, improving the service life of the drive motor, reducing the economic and time costs of equipment maintenance and repair, and improving production efficiency and economic benefits.

[0015] When the moving part needs to stop moving, the operating lever is moved to allow the reversing component to fall into the positioning groove. At this time, the reversing component is restricted within the positioning groove and cannot shift left or right. Simultaneously, the limiting components on both sides of the reversing component disengage the driving gears from the driven gears on both sides, allowing the driving gears and driven gears to idle, thus stopping the moving part. Conversely, if you want the moving part to continue its linear reciprocating motion, simply move the operating lever to allow the reversing component to leave the positioning groove, releasing the restriction on the reversing component. Due to the action of the tension spring, the reversing component deflects to one side, restoring the linear reciprocating motion of the moving part. This process does not require stopping the drive motor, avoiding frequent starting and stopping of the drive motor during operation, improving the service life of the drive motor, reducing the economic and time costs of equipment maintenance and repair, and improving production efficiency and economic benefits.

[0017] To better understand the purpose, structure, and function of this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] In the description of this invention, it should be understood that the terms "front," "rear," "left," "right," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0019] See Figures 1 to 10This embodiment discloses a linear automatic reversing mechanism, including a base 1, on which a drive motor 2 is mounted. The drive shaft of the drive motor 2 is connected to a drive gear 21. In this embodiment, the drive motor 2 drives the drive gear 21 to rotate to the right. The drive gear 21 meshes with a driven gear 22, which rotates to the left. The drive gear 21 and the driven gear 22 are respectively provided with connecting shafts 23. The front end of the connecting shaft 23 is slidably connected to a drive gear 24. In this embodiment, the connecting shaft 23 and the drive gear 24 are connected by an internal spline sleeve to achieve power transmission and to achieve the purpose of sliding connection between the connecting shaft 23 and the drive gear 24. The front end of the base 1 is provided with a support platform 11, and the support platform 11 is rotatably connected to a shaft 3. The rear end of the shaft 3 is provided with a driven gear 31 that matches the drive gear 24. The teeth of the driving gear 24 and the driven gear 31 are right-angled triangular teeth. One side of the teeth is designed with an inclined surface, so that the teeth gradually contact each other during meshing, reducing impact and noise. This helps the driving gear 24 and the driven gear 31 to smoothly complete the meshing and disengagement operations during rotation. The other side of the teeth is designed with a vertical surface, which improves the load-bearing capacity of the driving gear 24 and the driven gear 31 during meshing. It can be further optimized that the vertical surface of the teeth is consistent with the rotation direction of the driving gear 24 and the driven gear 31. A movable part 4 is slidably connected to the upper surface of the support platform 11. The shaft 3 is provided with a drive gear 32. A rack 41 that matches the drive gear 32 is fixed on the movable part 4. Through the meshing of the drive gear 32 and the rack 41, the drive gear 32 rotates and drives the rack 41 to move, thereby causing the movable part 4 to move.A fixing rod 12 is provided on the upper surface of the base 1. The fixing rod 12 is located between two driving gears 24. The fixing rod 12 is rotatably connected to a reversing component 5 and an adjusting component 6. The reversing component 5 and the adjusting component 6 can rotate about the fixing rod 12 as the central axis. The reversing component 5 and the adjusting component 6 are connected by a tension spring 8. In this embodiment, the upper surfaces of the reversing component 5 and the adjusting component 6 are respectively provided with positioning rods that can be hooked by the tension spring 8. The positioning rods are located at the front end of the adjusting component 6 and the rear end of the reversing component 5, respectively. A pushing component 42 is connected to the rear vertical surface of the moving component 4. Section 6 is equipped with a push rod 61 that mates with the pusher 42. The outer circumferential surface of the driving gear 24 has a limiting groove 241. The left and right sides of the reversing member 5 are respectively rotatably connected to limiting members 51 that mate with the limiting groove 241. The limiting members 51 are located within the limiting groove 241. When the linear reversing mechanism is running, the drive motor 2 drives the driving gear 21 to rotate, and the driving gear 21 drives the driven gear 22 to rotate. Since the driving gear 21 and the driven gear 22 mesh, their rotation directions are opposite. Due to the reversing... Component 5 and adjusting component 6 are connected by tension spring 8. At this time, reversing component 5 is biased to one side. Through the cooperation of limiting component 51 and limiting groove 241, the driving gear 24 on the biased side of reversing component 5 meshes with the driven gear 31. Through the cooperation of driving gear 32 and rack 41, moving component 4 is driven to move. As moving component 4 moves, pushing component 42 pushes push rod 61, causing adjusting component 6 to change its deflection direction. Through the contraction force of tension spring 8, reversing component 5 is biased to the other side. Through the cooperation of limiting component 51 and limiting groove 241... The driving gear 24 on the rearward-biased side of the reversing member 5 meshes with the driven gear 31, while the driving gear 24 and driven gear 31 on the previously biased side disengage. Since the driving gear 21 and driven gear 22 rotate in opposite directions, the moving member 4 moves in the opposite direction to the previous direction through the engagement of the driving gear 32 on the rearward-biased side and the rack 41. This achieves the automatic linear reversing of the moving member 4 without changing the forward or reverse rotation of the drive motor 2, avoiding frequent switching of the drive motor 2's forward and reverse rotation.

[0020] The rear facade of the movable component 4 is provided with a linear mounting groove 43, which is slidably connected to two pushers 42. The two pushers 42 and the linear mounting groove 43 are relatively slidable and fixed by bolts and nuts. By setting the distance between the two pushers 42, the travel distance of the reciprocating motion of the movable component 4 can be controlled, which increases the applicability of the linear automatic reversing mechanism. The adjusting component 6 is provided with push rods 61 on the left and right sides respectively. The two push rods 61 are located on the upper and lower surfaces of the adjusting component 6 respectively. In this embodiment, the push rod 61 near the left side is located on the lower surface of the adjusting component 6 and cooperates with the pusher 42 near the right side. The push rod 61 near the right side is located on the upper surface of the adjusting component 6 and cooperates with the pusher 42 near the left side. With this design, the pushers 42 on both sides will not be obstructed by the other push rod 61 during the movement. The contact surface between the pusher 42 and the push rod 61 is an inclined surface, which helps the push rod 61 to move along the inclined surface when the pusher 42 and the push rod 61 come into contact, thereby causing the direction of the adjusting component 6 to shift.

[0021] The upper surface of the support platform 11 is provided with a linear groove 111, and the lower surface of the moving part 4 is provided with a slider 44 that matches the linear groove 111. In this embodiment, the linear groove 111 is a trapezoidal groove, which can prevent the slider 44 from falling out of the linear groove 111. The moving part 4 achieves a sliding connection with the support platform 11 through the sliding cooperation between the slider 44 and the linear groove 111.

[0022] The rear face of the support platform 11 is provided with a shaft hole 112 for use with the shaft rod 3. The shaft rod 3 is rotatably connected to the support platform 11 by engaging with the shaft hole 112.

[0023] The upper surface of the base 1 is provided with limiting rods 14. The two limiting rods 14 are located on the left and right sides of the adjusting member 6 respectively. The position of the limiting rods 14 can ensure that the rotation angle of the adjusting member 6 is not too large, and can ensure that the pushing member 42 can contact the push rod 61 during the movement, and can push the push rod 61 to change the rotation direction of the adjusting member 6.

[0024] The rear end of the adjusting member 6 is provided with a positioning hole 62 that is used with the fixed rod 12. The adjusting member 6 is rotatably connected with the fixed rod 12 through the positioning hole 62 and the hole shaft of the fixed rod 12. The front end of the reversing member 5 is provided with a sleeve 52 that is used with the fixed rod 12. The reversing member 5 is rotatably connected with the fixed rod 12 through the sleeve 52 and the hole shaft of the fixed rod 12. In this embodiment, the top end of the fixed rod 12 is provided with a blocking member to prevent the reversing member 5 and the adjusting member 6 from falling off the fixed rod 12. The left and right sides of the sleeve 52 are respectively provided with connecting members 53. The connecting members 53 are provided with assembly holes 531. The limiting member 51 is provided with an assembly rod 511 that is used with the assembly hole 531. The limiting member 51 is rotatably connected with the connecting member 53 through the assembly rod 511 and the hole shaft of the assembly hole 531.

[0025] The connector 53 includes an upper connector and a lower connector. The driving gear 24 is located between the upper connector and the lower connector. By setting limiters 51 at both the upper and lower parts of the limit groove 241, the reliability of the limiters 51 in driving the driving gear 24 is increased, making the meshing and disengagement process of the driving gear 24 and the driven gear 31 more stable.

[0026] The base 1 has a mounting platform 13 at its rear end. The mounting platform 13 has a connecting through hole 131 that is used with the connecting shaft 23. The driving gear 21 and the driven gear 22 are respectively connected to the mounting platform 13 by the connecting shaft 23 and the hole shaft of the connecting through hole 131. The drive motor 2 is mounted on the rear vertical surface of the mounting platform 13.

[0027] The upper surface of the mounting platform 13 is provided with connecting ears 132 facing each other. A brake rod 7 is rotatably connected between the two connecting ears 132. In this embodiment, the connecting ears 132 and the brake rod 7 are rotatably connected by a hole shaft. The outer circumferential surface of the brake rod 7 is provided with a brake element 71. The brake element 71 is provided with limiting wings 711 on both sides. The brake element 71 is provided with a positioning groove 712 in the middle that is adapted to the reversing element 5. An operating rod 72 is provided on one side of the brake rod 7. The operating rod 72 is set perpendicular to the brake rod 7. When it is necessary to stop the movement of the moving part 4, the operating rod 72 is turned. The limiting wings 711 on both sides of the brake element 71 push the reversing element 5, so that the reversing element 5 falls into the positioning groove 712. At this time, the reversing element 5 is stopped. The reversing member 5 is confined within the positioning groove 712 and cannot shift left or right. The limiting members 51 on both sides of the reversing member 5 simultaneously disengage the driving gear 24 and driven gear 31 on both sides, causing the driving gear 21 and driven gear 22 to idle, thereby stopping the movement of the moving member 4. Conversely, if you want the moving member 4 to continue to perform linear reciprocating motion, you only need to turn the operating lever 72 to make the reversing member 5 leave the positioning groove 712, releasing the restriction on the reversing member 5. Due to the action of the tension spring 8, the reversing member 5 deflects to one side, restoring the linear reciprocating motion of the moving member 4. This process does not require stopping the drive motor 2, avoiding frequent starting and stopping of the drive motor 2 during operation.

[0028] A workbench includes a table surface and the aforementioned linear automatic reversing mechanism. The table surface and the moving part 4 are detachably connected. In this embodiment, the table surface is mounted on the moving part 4 by a bolt assembly.

[0029] Working principle: When the linear reversing mechanism is running, the drive motor 2 drives the driving gear 21 to rotate, and the driving gear 21 drives the driven gear 22 to rotate. Since the driving gear 21 and the driven gear 22 mesh, their rotation directions are opposite. Because the reversing component 5 and the adjusting component 6 are connected by the tension spring 8, the reversing component 5 is biased to one side. Through the cooperation of the limiting component 51 and the limiting groove 241, the driving gear 24 on the side of the reversing component 5 that is biased meshes with the driven gear 31. The engagement of the moving gear 32 and the rack 41 drives the moving part 4 to move. As the moving part 4 moves, the pushing part 42 pushes the push rod 61, causing the adjusting part 6 to change its deflection direction. Through the contraction force of the tension spring 8, the reversing part 5 is deflected to the other side. Through the engagement of the limiting part 51 and the limiting groove 241, the driving gear 24 on the side that the reversing part 5 is deflected to engages with the driven gear 31, while the driving gear 24 and the driven gear 31 on the side that was previously deflected to disengage. Due to the rotation of the driving gear 21 and the driven gear 22... In the opposite direction, the drive gear 32 on the rearward biased side engages with the rack 41 to drive the moving part 4 in the opposite direction to the previous direction. This achieves automatic linear reversal of the moving part 4 without changing the forward or reverse rotation of the drive motor 2, avoiding frequent switching of the drive motor 2's forward and reverse rotation. When the moving part 4 needs to stop moving, the operating lever 72 is moved, causing the reversing part 5 to fall into the positioning groove 712. At this time, the reversing part 5 is confined within the positioning groove 712 and cannot shift left or right. Simultaneously, the limiting pieces 51 on both sides of the reversing part 5... The driving gears 24 on both sides disengage from the driven gears 31, causing the driving gears 21 and driven gears 22 to idle, thus stopping the movement of the moving part 4. Conversely, if you want the moving part 4 to continue to move in a straight line, you only need to turn the operating lever 72 to make the reversing part 5 leave the positioning groove 712, releasing the restriction on the reversing part 5. Due to the action of the tension spring 8, the reversing part 5 deflects to one side, restoring the straight reciprocating motion of the moving part 4. This process does not require stopping the drive motor 2, avoiding frequent starting and stopping of the drive motor 2 during operation.
