Description

Technical Field

[0001] This utility model relates to the field of transmission slide technology, and in particular to a manually adjustable lead screw slide. Background Technology

[0002] The background of lead screw slides stems from the core industrial demand for precise linear displacement. Early mechanical movement relied on simple guide rails and lead screw transmission, but lacked a reliable locking design. Vibration could easily cause the slide to deviate, reducing the accuracy of processing, experimentation and other scenarios, and may also damage components. Although motor drive can run in a programmed manner, it is difficult to adapt to manual fine-tuning or emergency operation during power outages, and lacks flexibility.

[0003] Meanwhile, traditional limiters also rely on rigid collisions, which can easily cause vibrations that affect the stability of the workpiece, as well as damage the bottom structure of the slide, leading to frequent slide replacements and device damage.

[0004] Therefore, those skilled in the art have provided a manually adjustable lead screw slide to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a manually adjustable lead screw slide. By setting a lead screw nut on one side of the lead screw and a handwheel on the other end of the lead screw, the slide can be moved on the lead screw by manually turning the handwheel. Multiple fixing components are set on the lead screw to help fix the lead screw and prevent the lead screw from shifting during use. By setting a pneumatic buffer device, the impact generated when the slide moves quickly is buffered and other components on the base are protected.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A manually adjustable lead screw slide includes a base and a lead screw. Support blocks are connected to both ends of the bottom of the base. A baffle is connected to one end of the top of the base. A fixing block is provided at the other end of the top of the base. A fixing platform is provided on one side wall of the base. Pneumatic buffer mechanisms are provided on both sides of the top of the base. One side of the lead screw is connected to the side wall of the baffle. A sliding plate is provided on the top slide of the base. The pneumatic buffer mechanism includes a base. Positioning nuts are connected to both sides of the top of the base. Support plates are provided on both sides of the bottom of the base. A collar is connected to the center of the bottom of the base. A support column is provided at the center of the top of the base. A piston rod is provided at the top of the support column. Multiple telescopic rods are evenly arranged on the side wall of the piston rod. A fixing block is provided at the top of the piston rod.

[0008] Through the above technical solution, by setting up a pneumatic buffer device, when the slide table moves rapidly along the lead screw to the left and right extreme positions of the base, the piston rod of the buffer cylinder will first contact the slide table, and slowly absorb the kinetic energy of the slide table through the compression of the internal gas, so as to avoid rigid collision between the slide table and the base, thereby buffering the impact and protecting the components.

[0009] Furthermore, the support plates of the pneumatic buffer mechanism are fixed to both sides of the top of the base;

[0010] The above technical solution fixes the air pressure buffer mechanism to the base, preventing the excessive kinetic energy of the sliding plate from causing a rigid collision with the buffer mechanism.

[0011] Furthermore, the lead screw is connected through the slide plate, the fixing block, and the fixing platform, with one side of the lead screw connected to the side wall of the connecting block;

[0012] The above technical solution fixes the lead screw inside the base of the device, preventing the lead screw from shaking and damaging the device.

[0013] Furthermore, the connecting block is disposed inside the handwheel, and a handle for rotation is provided on the outer ring sidewall of the handwheel;

[0014] The above technical solution allows for manual rotation of the lead screw by setting a handwheel and a grip, thereby controlling the movement of the slide on the lead screw.

[0015] Furthermore, a lead screw nut is provided on one end of the lead screw that connects to the baffle, and a limit nut is provided on the lead screw nut;

[0016] The above technical solution involves setting a lead screw nut to ensure the smooth rotation of mechanisms such as the handwheel, thereby controlling the movement of the slide.

[0017] Furthermore, washers are provided on both side walls of the fixing block one;

[0018] The above technical solution protects the fixing blocks and other mechanisms when the internal sliding plate moves, reducing wear on the device.

[0019] Furthermore, a base plate is provided at the bottom of the fixing platform, and fixing nuts are provided on both sides of the top of the base plate;

[0020] The above technical solution fixes the mounting platform on the same plane as the base, preventing the lead screw from shifting and causing damage.

[0021] Furthermore, the collars in the pneumatic buffer mechanism are disposed on both sides of the lead screw;

[0022] The above technical solution protects the air pressure buffer mechanism and prevents the slide plate from rigidly colliding with the mechanism when the air pressure is insufficient.

[0023] This utility model has the following beneficial effects:

[0024] 1. The present invention proposes a manually adjustable lead screw slide table. By setting up a pneumatic buffer device, when the slide table moves rapidly along the lead screw to the left and right extreme positions of the base, the piston rod of the buffer cylinder will first contact the slide table. The kinetic energy of the slide table will be slowly absorbed by the compression of the internal gas, so as to avoid rigid collision between the slide table and the base. This buffers the impact generated when the slide table moves rapidly, and at the same time protects other components on the base and reduces the damage rate of manual control.

[0025] 2. The present invention proposes a manually adjustable lead screw slide, which sets a lead screw nut on one side of the lead screw and a handwheel or other control device on the other end of the lead screw, so as to realize the manual rotation of the handwheel to control the slide to move on the lead screw. In addition, multiple fixing components are set on the lead screw to help fix the lead screw, so as to prevent the lead screw from shifting during use and causing damage to the device.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figures 1-3 This utility model provides a specific implementation method:

[0035] A manually adjustable lead screw slide includes a base 9 and a lead screw 4. Support blocks 11 are connected to both ends of the bottom of the base 9, a baffle 10 is connected to one end of the top of the base 9, a fixing block 7 is provided at the other end of the top of the base 9, a fixing platform 8 is provided on one side wall of one end of the base 9, and pneumatic buffer mechanisms 6 are provided on both sides of the top of the base 9. One side of the lead screw 4 is connected to the side wall of the baffle 10, and a sliding plate 5 is provided on the top slide of the base 9. The pneumatic buffer mechanism 6 includes a base 608, positioning nuts 607 are connected to both sides of the top of the base 608, support plates 603 are provided on both sides of the bottom of the base 608, a collar 604 is connected to the center of the bottom of the base 608, a support column 606 is provided at the center of the top of the base 608, a piston rod 602 is provided on the top of the support column 606, multiple telescopic rods 605 are evenly arranged on the side wall of the piston rod 602, and a fixing block 601 is provided on the top of the piston rod 602.

[0036] Reference Figures 3-5 The lead screw 4 is connected to the slide plate 5, the fixed block 7, and the fixed platform 8. One side of the lead screw 4 is connected to the side wall of the connecting block 2. By setting up a pneumatic buffer device, when the slide plate moves rapidly along the lead screw to the left and right extreme positions of the base, the piston rod of the buffer cylinder will first contact the slide plate. The kinetic energy of the slide plate is slowly absorbed by the compression of the internal gas, avoiding a rigid collision between the slide plate and the base, thus buffering the impact and protecting the components. The pneumatic buffer mechanism is fixed on the base to prevent the slide plate from having too much kinetic energy and rigidly colliding with the buffer mechanism. The lead screw is fixed inside the base of the device to prevent the lead screw from shaking and damaging the device. The lead screw can be manually rotated by setting a handwheel and a handle to control the movement of the slide plate on the lead screw. The lead screw nut is set to ensure that the handwheel and other mechanisms rotate smoothly to control the movement of the slide plate. When the slide plate moves inside the device, it protects the fixed block and other mechanisms and reduces the wear of the device. The fixed platform is fixed on the same plane as the base to prevent the lead screw from shifting and causing damage. It also protects the pneumatic buffer mechanism to prevent a rigid collision between the slide plate and the mechanism when the air pressure is insufficient.

[0037] Working principle: When using this manually adjustable lead screw slide, first ensure that the lead screw 4 and the fixed block 7, baffle 10 and fixed platform 8 connected to it are completely fixed on the base 9. After confirming that everything is correct, you can manually hold the handle 3 and turn the handwheel 1 through the handle 3. At the same time, the lead screw nut 12 on one end of the lead screw 4 is fixed to the baffle 10. By rotating the lead screw 4, the slide plate 5 is controlled to move on the lead screw 4. At the same time, the air pressure buffer mechanism 6 is set on both sides of the lead screw 4. When the slide plate 5 moves quickly along the lead screw 4 to the left and right limit positions of the base, the piston rod 602 of the buffer cylinder will first contact the slide plate 5. The kinetic energy of the slide plate is slowly absorbed by the compression of the internal gas, avoiding a rigid collision between the slide plate and the base. Finally, the slide plate 5 stops to complete the process.
