Description

Technical Field

[0001] This utility model belongs to the field of semi-enclosed screw module technology, specifically a semi-enclosed screw module support frame. Background Technology

[0002] In the fields of industrial automation, precision manufacturing and intelligent equipment, semi-enclosed ball screw modules have become the core component for realizing linear transmission due to their combination of dust protection and ease of maintenance. They are widely used in scenarios such as electronic component assembly, CNC machine tool feed systems, 3D printing equipment drives, and precision positioning of medical instruments.

[0003] Existing semi-enclosed lead screw module support frames mostly adopt a "fixed-size integrated structure," where the length and span parameters of the support frame and mounting base are bound to a specific model of lead screw module, forming a "one-to-one" adaptation relationship. For example, a support frame designed for a 1000mm long lead screw module cannot directly install modules with a length of 800mm or 1200mm. If the module length is shorter, the spacing between support points will be too large, making the lead screw prone to deflection and deformation during operation, affecting transmission accuracy. If the module length is longer, the support frame needs to be recut and welded, or the entire support frame needs to be replaced. This fixed adaptation mode brings multiple problems: cost waste: equipment manufacturers need to stock multiple specifications of support frame spare parts for modules of different lengths, increasing inventory costs by 30% to 50%; low efficiency: when upgrading production lines or modifying equipment, replacing modules requires replacing the support frame simultaneously, resulting in extended downtime (usually 4 to 8 hours) and affecting production progress.

[0004] Therefore, this utility model provides a semi-enclosed screw module support frame. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, a semi-enclosed screw module support frame is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A semi-enclosed screw module support frame of this utility model includes a base plate; legs are fixedly installed on both sides of the bottom of the base plate, a sliding mechanism is provided on the top of the base plate, and a support mechanism is provided on the top of the sliding mechanism; an adjustment mechanism is provided in the middle of the top of the base plate, and a telescopic mechanism is provided on the top of the adjustment mechanism; an anti-wear mechanism is provided on the top of the inner wall of the sliding block, and a drive component is provided in the guide groove opened on the top of the base plate; the sliding mechanism includes a guide groove, a sliding block, and a cylinder; the guide groove is opened on both sides of the top of the base plate; two sets of sliding blocks are provided, and the two sets of sliding blocks are slidably installed in the guide groove opened on both sides of the top of the base plate; the top of the sliding block is fixedly installed with the cylinder; the opening of the guide groove can make the sliding block more stable during sliding and prevent deviation, while ensuring that the accuracy after adjustment can reach a high level; the cooperation between the sliding block and the cylinder can control the height of the L-shaped plate, thereby achieving the effect of adjusting the height of the semi-enclosed screw module.

[0007] Preferably, the support mechanism includes an L-shaped plate, a mounting hole, and a support cross plate. The L-shaped plate is fixedly installed at the output end of the cylinder. A mounting hole is provided on one side of the surface of the L-shaped plate. The bottom of the L-shaped plate near the mounting hole is fixedly installed with the support cross plate. In this scheme, the cooperation between the L-shaped plate and the support cross plate can provide stable support and limiting function for the semi-enclosed screw module. At the same time, the semi-enclosed screw module can be firmly fixed through the mounting hole.

[0008] Preferably, the adjustment mechanism includes a fixed plate, a first forward and reverse lead screw, and a rocker arm. The fixed plate is fixedly installed in the middle of the top of the base plate. The inner wall of the top of the fixed plate is rotatably installed with the first forward and reverse lead screw. One side of the fixed plate is rotatably installed with the rocker arm. The side of the rocker arm closest to the fixed plate is fixedly installed with the first forward and reverse lead screw. In this scheme, the combined use of the fixed plate, the first forward and reverse lead screw, and the rocker arm can achieve the effect of adjusting the distance between the two sets of fixed support rods by the user's drive. This allows it to adapt to the width of different semi-enclosed lead screw modules, improves device compatibility, and is not easily damaged by manual drive, making maintenance convenient.

[0009] Preferably, the telescopic mechanism includes a fixed support rod, a telescopic rod, and a support frame. Two sets of fixed support rods are provided, and the two sets of fixed support rods are threaded onto both ends of the surface of the first forward and reverse lead screw. The inner wall of the top of the fixed support rod is slidably connected to the telescopic rod, and the top of the telescopic rod is fixedly installed to the support frame. In this design, the cooperation between the fixed support rod and the telescopic rod enables the support frame to extend and retract according to the rising of the semi-enclosed lead screw module, thereby ensuring that the support frame can always provide effective support to the semi-enclosed lead screw module.

[0010] Preferably, the anti-wear mechanism includes a groove, a connecting frame, and a roller. The groove is formed on the top of the base plate, and the connecting frame is fixedly installed on both sides of the top of the inner wall of the sliding block. The inner wall of the connecting frame is rotatably installed with the roller. The roller is located in the groove formed on the top of the base plate and is rotatably connected to the base plate. In this design, the groove allows the roller to slide within the groove when the sliding block moves, preventing it from shifting. The cooperation between the connecting frame and the roller prevents friction when the sliding block moves and also makes the adjustment of the sliding block smoother and less strenuous.

[0011] Preferably, the drive assembly includes a second forward and reverse screw and a knob. The second forward and reverse screw is rotatably mounted in a guide groove opened on one side of the top of the base plate, and the knob is rotatably mounted on the side of the base plate near the second forward and reverse screw. The second forward and reverse screw and the knob are fixedly connected. In this scheme, the cooperation between the second forward and reverse screw and the knob can drive the two sets of sliding blocks to move by the user, so that the sliding blocks can drive the L-shaped plate to adjust, and achieve the effect of adapting to semi-enclosed screw modules of different lengths.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The semi-enclosed screw module support frame of this utility model, through the setting of guide groove, sliding block, cylinder, L-shaped plate, mounting hole and support cross plate, makes the opening of guide groove so that the sliding block is more stable during sliding and will not deviate, while ensuring that the accuracy after adjustment can reach a high level. The cooperation between the sliding block and the cylinder can control the height of the L-shaped plate, thereby realizing the effect of adjusting the height of the semi-enclosed screw module. The cooperation between the L-shaped plate and the support cross plate can provide stable support and limit function for the semi-enclosed screw module, and the mounting hole can firmly fix the semi-enclosed screw module.

[0014] 2. The semi-enclosed screw module support frame of this utility model, through the arrangement of a fixed plate, a first forward and reverse screw, a rocker arm, a fixed support rod, a telescopic rod, and a support frame, allows the fixed plate, the first forward and reverse screw, and the rocker arm to adjust the distance between the two sets of fixed support rods by the user. This enables it to adapt to the width of different semi-enclosed screw modules, improving device compatibility. Furthermore, manual operation is less prone to damage, and maintenance is convenient. The cooperation between the fixed support rod and the telescopic rod allows the support frame to extend and retract according to the rise of the semi-enclosed screw module, ensuring that the support frame always provides effective support to the semi-enclosed screw module.

On the side, two sets of sliding blocks 32 are provided, and the two sets of sliding blocks 32 are slidably installed in the guide grooves 31 opened on both sides of the top of the base plate 1. The top of the sliding blocks 32 is fixedly installed with the cylinder 33. The support mechanism 4 includes an L-shaped plate 41, a mounting hole 42 and a support cross plate 43. The L-shaped plate 41 is fixedly installed at the output end of the cylinder 33. A mounting hole 42 is opened on one side of the surface of the L-shaped plate 41. The bottom of the L-shaped plate 41 near the mounting hole 42 is fixedly installed with the support cross plate 43. The adjustment mechanism 5 includes a fixed plate 51, a first forward and reverse lead screw 52 and a rocker arm 53. The fixed plate 51 is fixedly installed on the top of the base plate 1. In the middle, the inner wall of the top of the fixed plate 51 is rotatably mounted to the first forward and reverse lead screw 52. One side of the fixed plate 51 is rotatably mounted to the rocker arm 53. The side of the rocker arm 53 near the fixed plate 51 is fixedly mounted to the first forward and reverse lead screw 52. The telescopic mechanism 6 includes a fixed support rod 61, a telescopic rod 62, and a support frame 63. Two sets of fixed support rods 61 are provided, and the two sets of fixed support rods 61 are threaded onto both ends of the surface of the first forward and reverse lead screw 52. The inner wall of the top of the fixed support rod 61 is slidably connected to the telescopic rod 62. The top of the telescopic rod 62 is fixedly mounted to the support frame 63. The anti-wear mechanism 7 includes a groove 71. The connecting frame 72 and the roller 73 are provided. The groove 71 is opened on the top of the base plate 1. The connecting frame 72 is fixedly installed on both sides of the top of the inner wall of the sliding block 32. The inner wall of the connecting frame 72 is rotatably installed with the roller 73. The roller 73 is located in the groove 71 opened on the top of the base plate 1. The roller 73 is rotatably connected to the base plate 1. The driving assembly 8 includes a second forward and reverse screw 81 and a knob 82. The second forward and reverse screw 81 is rotatably installed in the guide groove 31 opened on one side of the top of the base plate 1. The knob 82 is rotatably installed on the side of the base plate 1 near the second forward and reverse screw 81. The second forward and reverse screw 81 and the knob 82 are fixedly connected.

[0026] like Figures 1 to 5As shown, the guide groove 31 makes the sliding block 32 more stable during sliding and prevents it from shifting, while ensuring a high level of accuracy after adjustment. The sliding block 32 and the cylinder 33 work together to control the height of the L-shaped plate 41, thereby achieving the effect of adjusting the height of the semi-enclosed screw module. The L-shaped plate 41 and the support plate 43 work together to provide stable support and limit function for the semi-enclosed screw module. At the same time, the semi-enclosed screw module can be firmly fixed through the mounting hole 42. The fixed plate 51, the first forward and reverse screw 52 and the rocker arm 53 work together to adjust the distance between the two sets of fixed support rods 61 by the user, thereby adapting it to the width of different semi-enclosed screw modules, improving the compatibility of the device, and making manual driving less difficult. The system is designed for easy maintenance and repair. The combination of the fixed support rod 61 and the telescopic rod 62 allows the support frame 63 to extend and retract according to the rise of the semi-enclosed screw module, thus ensuring that the support frame 63 can always provide effective support for the semi-enclosed screw module. The groove 71 allows the roller 73 to slide within the groove 71 when the sliding block 32 moves, preventing it from shifting. The combination of the connecting frame 72 and the roller 73 prevents friction when the sliding block 32 moves, and also makes the adjustment of the sliding block 32 smoother and less strenuous. The combination of the second forward and reverse screw 81 and the knob 82 allows the user to drive the two sets of sliding blocks 32 to move, thereby enabling the sliding block 32 to drive the L-shaped plate 41 for adjustment, achieving the effect of adapting to semi-enclosed screw modules of different lengths.

[0027] Working principle: During operation, first place the base plate 1 on a flat surface. Then, the user turns the knob 82 to drive the second forward and reverse screw 81 to rotate. When the second forward and reverse screw 81 rotates, it drives the two sets of sliding blocks 32 to move synchronously towards the center. As the sliding blocks 32 continue to move, the distance between the two sets of L-shaped plates 41 gradually shortens until it is shortened to the same length as the semi-enclosed screw module. Then, the rocker arm 53 is turned again to drive the first forward and reverse screw 52 to rotate. The rotation of the first forward and reverse screw 52 will drive the two sets of fixed support rods 61 to move synchronously. As the fixed support rod 61 moves, the distance between the support frames 63 will shorten until it is equal to the width of the semi-enclosed screw module. Then, the user places the semi-enclosed screw module on top of the support plate 43 and then fixes the semi-enclosed screw module through the mounting hole 42. After installation, the user can start the cylinder 33 to push the L-shaped plate 41 up. When the L-shaped plate 41 rises, it will lift the semi-enclosed screw module through the support plate 43. At the same time, the support frame 63 will also drive the telescopic rod 62 to rise and fall synchronously with the semi-enclosed screw module.
