In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0035] Linear guides require high machining accuracy during manufacturing, especially when grinding their outer surfaces. To ensure the length of the linear guide aligns with the working direction of the grinding machine, precise positioning is typically necessary. Existing linear guide positioning devices are often complex in structure, making them difficult to adapt to linear guides of varying lengths. Furthermore, the positioned components may obstruct parts of the linear guide's outer surface, thus affecting the efficiency and quality of subsequent grinding processes.

[0036] Therefore, such as Figure 1 and Figure 2As shown, the linear guide positioning device proposed in this utility model includes a base 100, a worktable 200 connected to the base 100, and a positioning module 300 connected to the base 100. The worktable 200 is provided with a support block 210 suitable for supporting the bottom wall of the linear guide. The positioning module 300 includes a first drive assembly 310, a swing arm 320, a drive cylinder 330, and a positioning block 340 connected in sequence. Specifically, the first drive assembly 310 is connected to and drives the swing arm 320 to swing along the side facing the support block 210, thereby driving the drive cylinder 330 to be positioned above the support block 210. Further, the swing arm 320 is connected to and drives the positioning block 340 to move downwards in a vertical direction. The positioning block 340 is provided with a positioning groove 341, and an opening 342 for the linear guide to pass through is provided below the positioning groove 341. The opposite groove wall of the positioning groove 341 is used to position the opposite side wall of the linear guide. It should be noted that the positioning module 300 realizes the positioning function of the linear guide. When the positioning block 340 moves downward, the positioning groove 341 on the positioning block 340 cooperates with the side wall of the linear guide to ensure that the linear guide is placed on the support block 210. This ensures that the length direction of the linear guide is consistent with the working transport of the grinding machine 400, which facilitates subsequent grinding operations. After positioning is completed, the drive cylinder 330 drives the positioning block 340 to move upward to disengage from the linear guide. Then, the first drive component 310 drives the swing arm 320 away from the support block 210. This avoids the problem of limited grinding range caused by obstructing the outer surface of the linear guide, thereby improving the efficiency of the entire processing process and the processing quality of the product.

[0037] In some embodiments, the first drive assembly drives the swing arm to swing in the vertical plane, reducing the space occupied laterally and facilitating the installation of multiple positioning modules with small horizontal spacing, resulting in a denser array of positioning and mating points for the linear guide rail. In some embodiments of this invention, such as... Figure 1 As shown, the first drive assembly 310 is a horizontal turntable. The horizontal turntable connects to and drives the swing arm 320 to swing back and forth in the horizontal plane, ensuring that the swing arm 320 swings back and forth stably and smoothly in the horizontal plane. The design of the swing arm 320 swinging in the horizontal plane not only simplifies the motion control of the positioning module 300 and improves the reliability and positioning accuracy of the swing arm 320's motion, but also further improves the accuracy of the linear guide rail positioning, thereby ensuring the quality of subsequent grinding processing.

[0038] In some embodiments of this utility model, such as Figure 1 and Figure 4As shown, there are multiple support blocks 210 arranged linearly at intervals, which support the bottom wall of the linear guide rail at intervals. This effectively reduces the impact of manufacturing errors in the bottom wall of the linear guide rail on its positioning. Furthermore, it can better support linear guide rails of different lengths, ensuring their stability during the positioning process and reducing the risk of bending deformation during machining. In addition, this design allows it to adapt to a wider range of linear guide rail sizes, resulting in better versatility.

[0039] It should be noted that the positioning block 340 only needs to move downwards, without actively clamping the opposite sidewalls of the linear guide rail inwards, to achieve the positioning of the linear guide rail. For example, an external robot arm places the linear guide rail on the support block 210 to complete the initial positioning, and then the positioning block 340 is used to perform secondary positioning of the linear guide rail. (Refer to...) Figure 2 and Figure 3 In some embodiments of this utility model, the positioning groove 341 includes a first positioning segment 3411 and a second positioning segment 3412 that are interconnected. The relative groove wall of the first positioning segment 3411 abuts against the relative side wall of the support block 210, and the relative groove wall of the second positioning segment 3412 positions the relative side wall of the linear guide rail. It is readily understood that the first positioning segment 3411 uses the support block 210 as a mating reference, and the second positioning segment 3412 mates with the side wall of the linear guide rail, so that the linear guide rail is precisely positioned on the support block 210, ensuring the position of the linear guide rail on the support block 210. Optionally, the center line of the first positioning segment 3411 and the center line of the second positioning segment 3412 are in the same vertical plane, so that after the positioning block 340 is fitted into the support block 210, the linear guide rail is located in the center position on the support block 210. Furthermore, an arc-shaped transition wall 3413 is provided between the first positioning section 3411 and the second positioning section 3412. This reduces stress concentration when the positioning block 340 contacts the linear guide rail, preventing deformation or damage to the linear guide rail during positioning and further ensuring the quality and machining accuracy of the linear guide rail. In addition, the arc-shaped transition wall 3413 can also improve the contact state of the linear guide rail during positioning, reduce wear, and extend the service life of the positioning block 340.

[0040] Furthermore, refer to Figure 2The support block 210 includes a base 211 and a support portion 212. The horizontal cross-sectional area of ​​the support portion 212 is smaller than that of the base 211. The support portion 212 protrudes upward from the base 211. The linear guide rail is placed on the end face of the support portion 212. The opposite groove wall of the first positioning segment 3411 abuts against the opposite side wall of the base 211, effectively reducing the friction between the linear guide rail and the positioning block 340. This helps improve the accuracy and stability of the linear guide rail positioning and also reduces the risk of damage to the linear guide rail during the positioning process. In some embodiments, the base 211 is used to connect with the worktable 200, and the support portion 212 is integrally connected to the base 211 and positioned in the center of the base 211. Optionally, the width of the support portion 212 is smaller than the maximum width of the linear guide rail, so that the groove wall of the second positioning segment 3412 will not collide with the support portion 212 during the positioning process of the positioning block 340 positioning the linear rail.

[0041] Refer to Figure 1 In some embodiments of this utility model, the positioning module 300 includes a second driving component 350, which connects to and drives the first driving component 310 to move vertically. This allows for vertical adjustment of the positioning module 300, enabling precise adjustment of the positioning device according to linear guides of different heights, thus improving positioning accuracy and applicability. Optionally, the second driving component 350 is a screw jack with a self-locking function, ensuring high safety during use.

[0042] Furthermore, referring to Figure 4 In some embodiments of this utility model, there are multiple positioning modules 300, which are linearly spaced on the same side of the base 100. This ensures that linear guides of different lengths can be effectively supported and positioned. This multi-point positioning method improves the stability of linear guide positioning, especially for longer linear guides, better preventing bending or offset during processing, thereby improving processing accuracy and product quality. Optionally, the distance between two adjacent positioning modules 300 is greater than 1000mm, which can reduce the number of positioning modules 300 while ensuring the positioning stability of the linear guide, thus reducing the cost and complexity of the device. This layout ensures the stability of the linear guide during positioning, improves the economy and practicality of the entire positioning device, and reduces maintenance costs. Optionally, the distance between the two furthest positioning modules 300 is less than 4500mm, which ensures the overall stability and positioning accuracy of the linear guide during processing. This distance setting can meet the length requirements of most linear guides, ensure the stability of the linear guide during positioning, and improve processing quality and efficiency. At the same time, this design also ensures the compactness and economy of the positioning device, which is beneficial for production line space planning and cost control.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
