Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission component assembly technology, and in particular to a quick assembly device for a dustproof sheet and a bead protector by a snap-fit ​​mechanism. Background Technology

[0002] In industrial robots, precision grinding machines, and other equipment that rely on high-precision transmission, the lead screw drive system is a core component for achieving precise displacement control. The lead screw slider, as a key component for load-bearing and transmission, requires its outer wall to have continuously cleaned ball helical grooves to ensure smooth ball circulation. A ball guard block must be fitted to the lead screw slider to limit the ball's movement trajectory and prevent it from dislodging from the groove. A dustproof sheet must cover the assembly area of ​​the lead screw slider to prevent metal shavings, cutting fluid mist, and environmental dust generated during processing from entering. The coordinated work of these three components is crucial for maintaining the positioning accuracy and service life of the lead screw drive system.

[0003] Current assembly methods for protective bead blocks and dustproof sheets have significant limitations: most methods use multiple sets of bolts for step-by-step connection, requiring repeated calibration of the hole positions of the protective bead blocks, dustproof sheets, and lead screw sliders during assembly, and the use of wrenches and other tools to tighten each bolt individually, making the operation cumbersome and extremely inefficient, especially in batch assembly scenarios; some methods use adhesive fixing, which not only takes a long time to cure, but also requires external force to break the adhesive layer to separate the parts during later maintenance, which can easily damage the protective bead blocks or dustproof sheets and increase replacement costs. Therefore, we propose a snap-fit ​​quick assembly device for dustproof sheets and protective bead devices to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and to propose a quick assembly device for dustproof sheet and bead protector by snap-fit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-assembly device for dustproof sheet and ball protector with snap-fit ​​mechanism includes a lead screw slider, a ball protector block, and a dustproof sheet. The outer wall of the lead screw slider is provided with a ball spiral groove, and the outer wall of the lead screw slider is provided with an assembly hole that matches the ball spiral groove. The outer walls of the ball protector block and the dustproof sheet are slidably connected to the inner wall of the assembly hole. The ball protector block and the dustproof sheet are connected by a snap-fit ​​mechanism.

[0007] The buckling mechanism includes a mounting hole on the top of the bead protector block. An inverted T-shaped rod is slidably connected to the inner wall of the mounting hole. The bottom of the inverted T-shaped rod and the bottom of the mounting hole are fixedly connected by a spring. A connecting plate is fixedly installed at the top of the inverted T-shaped rod. Multiple connecting holes are opened at the top of the connecting plate. Multiple buckle rubber plugs are located at the bottom of the dustproof sheet. The outer wall of the buckle rubber plug and the inner wall of the connecting hole are slidably connected in the vertical direction.

[0008] Preferably, the two ends of the spring are fixedly connected to the bottom of the inverted T-shaped rod and the bottom of the mounting hole, respectively.

[0009] Preferably, the plurality of connecting holes are arranged in a ring array on the top of the connecting plate, and the plurality of snap-fit ​​rubber plugs are arranged in a ring array on the bottom of the inverted T-shaped rod.

[0010] Preferably, the dustproof sheet and the outer wall of the lead screw slider are fixed together by multiple bolts, and the outer wall of the lead screw slider is provided with multiple threaded holes that are compatible with the bolts.

[0011] Preferably, an annular sealing gasket is fixedly sleeved on the outer wall of the buckle rubber plug.

[0012] Preferably, multiple positioning protrusions are fixedly installed on the outer sidewalls of the protective bead block and the dustproof sheet, and two positioning grooves adapted to the positioning protrusions are opened on the inner sidewall of the assembly hole, and the outer sidewall of the positioning protrusion is slidably connected to the inner sidewall of the positioning groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] The snap-fit ​​mechanism allows for quick docking of the protective bead block and the dustproof sheet, enabling assembly without complex tools and significantly improving assembly efficiency. The positioning protrusion and positioning groove work together to ensure precise installation and prevent hole misalignment. The annular sealing gasket fills the gaps to enhance the dustproof effect, and the bolts further reinforce the connection between the dustproof sheet and the lead screw slider. Disassembly only requires pressing the dustproof sheet to release the snap-fit, facilitating later maintenance and reducing component damage. It balances efficient assembly, stable protection, and convenient maintenance, making it suitable for the needs of precision transmission equipment. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A quick-assembly device for dustproof sheet and bead protector with snap-fit ​​mechanism includes a lead screw slider 1, a bead protector block 2, and a dustproof sheet 3. The lead screw slider 1 has a ball spiral groove 4 on its outer wall and an assembly hole 5 on its outer wall that matches the ball spiral groove 4. The outer walls of both the bead protector block 2 and the dustproof sheet 3 are slidably connected to the inner wall of the assembly hole 5. The bead protector block 2 and the dustproof sheet 3 are connected by a snap-fit ​​mechanism. The snap-fit ​​mechanism includes an installation hole 6 on the top of the bead protector block 2. An inverted T-shaped rod 7 is slidably connected to the inner wall of the installation hole 6. The bottom of the inverted T-shaped rod 7 and the bottom of the installation hole 6 are fixedly connected by a spring 8. A connecting plate 9 is fixedly installed at the top of the inverted T-shaped rod 7. Multiple connecting holes 10 are provided on the top of the connecting plate 9. Multiple snap-fit ​​rubber plugs 11 are located at the bottom of the dustproof sheet 3. The outer walls of the vertical snap-fit ​​rubber plugs 11 are slidably connected to the inner walls of the connecting holes 10.

[0022] To further explain, by opening the assembly hole 5 on the lead screw slider 1, the ball guard block 2 and the dustproof sheet 3 can be precisely fitted and installed; the snap-fit ​​mechanism uses the cooperation of the inverted T-shaped rod 7, spring 8, connecting plate 9 and snap-fit ​​rubber bolt 11 to allow the ball guard block 2 and the dustproof sheet 3 to be quickly snapped together, and the assembly can be completed without complicated tools, which greatly improves the assembly efficiency; at the same time, the dustproof sheet 3 can prevent impurities from entering the ball spiral groove 4, ensuring the stable transmission of the lead screw slider 1, and taking into account both the functions of quick assembly and dust protection.

[0023] like Figure 2 As shown, the two ends of the spring 8 are fixed to the bottom of the inverted T-shaped rod 7 and the bottom of the mounting hole 6, respectively.

[0024] To further clarify, the fixed connection method at both ends of the spring 8 is specified to ensure that the spring 8 is stably fixed in the mounting hole 6, to avoid the spring 8 shifting and causing the inverted T-shaped rod 7 to slide and jam, to ensure that the inverted T-shaped rod 7 in the buckling mechanism can move smoothly up and down, to make the buckling connection or separation process between the protective bead block 2 and the dustproof original sheet 3 more reliable, and to maintain the long-term stable operation of the buckling mechanism.

[0025] like Figure 2 As shown, multiple connecting holes 10 are arranged in a ring array on the top of the connecting plate 9, and multiple snap-fit ​​rubber bolts 11 are arranged in a ring array on the bottom of the inverted T-shaped rod 7.

[0026] To further explain, the connecting hole 10 and the snap-fit ​​rubber plug 11 are both arranged in a ring array, which can ensure that the force is evenly distributed when the two are connected, and avoid excessive local force that could cause deformation of the snap-fit ​​rubber plug 11 or damage to the connecting plate 9. At the same time, the ring array distribution makes the connection between the protective bead block 2 and the dustproof sheet 3 more stable, reducing the possibility of loosening due to uneven force after assembly, and improving the overall structural stability.

[0027] like Figure 1 and 3 As shown, the dustproof sheet 3 and the outer wall of the lead screw slider 1 are fixed together by multiple bolts 12, and multiple threaded holes adapted to the bolts 12 are provided on the outer wall of the lead screw slider 1.

[0028] To further explain, a threaded hole adapted to the bolt 12 is opened on the lead screw slider 1, so that the bolt 12 can be precisely screwed in to fix the dustproof sheet 3 to the lead screw slider 1. Compared with other connection methods, the threaded connection is more secure and facilitates disassembly and maintenance in the future. At the same time, the setting of the threaded hole ensures that the bolt 12 is installed in a precise position, avoiding the impact of installation deviation on the dustproof effect of the dustproof sheet 3 and the overall structural stability.

[0029] like Figure 2 As shown, an annular sealing gasket 13 is fixedly sleeved on the outer wall of the snap-fit ​​rubber plug 11.

[0030] To further explain, the annular sealing gasket 13 on the outside of the snap-fit ​​rubber plug 11 can fill the tiny gap between the snap-fit ​​rubber plug 11 and the connecting hole 10, preventing dust, debris and other impurities from entering the assembly hole 5 through the gap, thereby further improving the dustproof performance of the device; at the same time, the annular sealing gasket 13 can increase the friction between the snap-fit ​​rubber plug 11 and the connecting hole 10, reduce the relative sliding between the two, and make the snap-fit ​​connection between the protective bead block 2 and the dustproof original sheet 3 tighter, reducing the risk of loosening.

[0031] like Figure 2 and Figure 4As shown, multiple positioning protrusions 14 are fixedly installed on the outer walls of the protective bead block 2 and the dustproof original sheet 3. Two positioning grooves 15 adapted to the positioning protrusions 14 are opened on the inner wall of the assembly hole 5. The outer wall of the positioning protrusions 14 is slidably connected to the inner wall of the positioning grooves 15.

[0032] To further explain, the positioning protrusions 14 on the bead protector block 2 and the dustproof sheet 3 slide in conjunction with the positioning grooves 15 in the assembly hole 5, which can provide precise guidance for the bead protector block 2 and the dustproof sheet 3 during installation, avoiding misalignment of the snap-fit ​​mechanism or failure of the seal of the dustproof sheet 3 due to installation misalignment; at the same time, the cooperation between the positioning protrusions 14 and the positioning grooves 15 can limit the rotation of the bead protector block 2 and the dustproof sheet 3, ensuring that the positions of the two are stable during use, and ensuring the transmission accuracy and dustproof effect of the device.

[0033] The functional principle of this utility model can be explained through the following operation methods:

[0034] When installing the protective bead block 2, align the positioning protrusion 14 on the outer wall of the protective bead block 2 with the positioning groove 15 on the inner wall of the assembly hole 5, and push the protective bead block 2 smoothly into the assembly hole 5 along the direction of the positioning groove 15 until the protective bead block 2 reaches the preset installation position. At this time, the positioning protrusion 14 is fully embedded in the positioning groove 15, which restricts the rotation of the protective bead block 2 in the assembly hole 5.

[0035] When installing the dustproof sheet 3, first align the positioning protrusion 14 on the outer wall of the dustproof sheet 3 with the positioning groove 15 in the assembly hole 5, and at the same time, make the buckle rubber bolt 11 at the bottom of the dustproof sheet 3 correspond to the position of the connecting hole 10 at the top of the connecting plate 9. Slowly push the dustproof sheet 3 into the assembly hole 5. During the process, the positioning protrusion 14 slides along the positioning groove 15 to ensure that the installation direction of the dustproof sheet 3 is accurate.

[0036] Continue pushing the dustproof sheet 3 so that the snap-fit ​​rubber plug 11 is gradually inserted into the connecting hole 10. At this time, the connecting plate 9 moves downward under the pressure of the snap-fit ​​rubber plug 11, causing the inverted T-shaped rod 7 to slide downward in the mounting hole 6. The spring 8 is compressed and generates an elastic force. When the snap-fit ​​rubber plug 11 has completely passed through the connecting hole 10, the annular sealing gasket 13 is tightly attached to the top of the connecting plate 9. The elastic force of the spring 8 pushes the inverted T-shaped rod 7 to reset, so that the connecting plate 9 presses against the snap-fit ​​rubber plug 11 upward, completing the snap-fit ​​connection between the protective bead block 2 and the dustproof sheet 3.

[0037] After the buckle connection is completed, pass the bolt 12 through the reserved hole on the dustproof sheet 3, align it with the threaded hole on the outer wall of the lead screw slider 1, and rotate the bolt 12 clockwise until it is tightened, so that the dustproof sheet 3 and the lead screw slider 1 are firmly fixed. At this time, the dustproof sheet 3, the protective ball block 2 and the lead screw slider 1 form an integral assembly structure.

[0038] For disassembly and maintenance, first rotate the bolt 12 counterclockwise to remove it from the threaded hole, thus releasing the dustproof sheet 3 from the lead screw slider 1; then press the dustproof sheet 3 down to push the connecting plate 9 and the inverted T-shaped rod 7 down with the snap-fit ​​rubber bolt 11, and the spring 8 will be compressed again. After the snap-fit ​​rubber bolt 11 is released from the connecting hole 10, pull the dustproof sheet 3 outward so that it slides out of the assembly hole 5 along the positioning groove 15; finally, remove the protective bead block 2 from the assembly hole 5 along the positioning groove 15, and then you can inspect or replace each component.

[0039] After maintenance, reverse the installation steps described above and install the protective bead block 2 and the dustproof sheet 3 into the assembly hole 5 in sequence. Ensure that the positioning protrusion 14 is accurately embedded in the positioning groove 15, the buckle rubber bolt 11 is precisely aligned with the connection hole 10, and the bolt 12 is firmly tightened to restore the device to normal operating condition.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
