[0001] This utility model belongs to the field of guide rail processing technology, specifically relating to a precision handling device for linear guide rail processing. Background Technology

[0002] Linear guides, as core components of precision mechanical transmission systems, are widely used in high-precision fields such as CNC machine tools, automated production lines, and semiconductor equipment. Their machining accuracy and assembly quality directly affect the smoothness of movement, positioning accuracy, and service life of the equipment. During the production process of linear guides, the workpiece needs to undergo multiple handling, positioning, and clamping operations.

[0003] During product handling, it is necessary to limit the clamping and fixing of the product to ensure the stability and safety of the equipment during handling. When using spring-limited fixing, it is difficult to effectively limit multiple flexible segments, and relying solely on the elastic clamping of the spring poses potential risks. Summary of the Invention

[0034] Example 1

[0035] Please refer to Figures 1-7. This utility model provides the following technical solutions:

[0036] A precision handling device for linear guide machining includes:

[0037] Mobile component 100;

[0038] And, a placement component 300 connected to the drive end of the moving component 100 to perform transport operations;

[0039] Clamping component 500 is used to limit the clamping operation of the placement component 300;

[0040] The placement assembly 300 includes a placement platform 301, a pull plate 302, a spring 303, a pull rod 304, and a clamping plate 305;

[0041] The clamping plate 305 is located on one side of the placement platform 301, the pull rod 304 is slidably connected to the placement platform 301, the pull rod 304 is fixedly connected to one side of the clamping plate 305, the spring 303 is sleeved on the circumferential surface of the pull rod 304, and the pull plate 302 is fixedly connected to the other side of the pull rod 304.

[0042] The clamping assembly 500 includes a groove 501, a first insertion hole 502, an insertion rod 503, a slide rod 504, and a second insertion hole 505;

[0043] A groove 501 is formed on one side of the placement platform 301. A slide rod 504 is slidably connected in the groove 501. One end of the slide rod 504 passes through the placement platform 301 and is fixed to the pull plate 302. An insert rod 503 is located in the groove 501 to restrict the slide rod 504.

[0044] The moving assembly 100 includes a worktable 101, an upper plate 102, a motor 103, a lead screw 104, and a slider 105;

[0045] The upper plate 102 is fixedly connected to the upper end of the worktable 101, the motor 103 is fixedly connected to one side of the worktable 101, the slider 105 is slidably connected inside the worktable 101, the lead screw 104 is located inside the worktable 101, the slider 105 is threadedly connected to the circumferential surface of the lead screw 104 through a nut, and the lead screw 104 is fixed to the output shaft of the motor 103.

[0046] The limiting component 200 includes a limiting rod 201, a support block 202, and a limiting slide plate 203;

[0047] The limiting rod 201 is located inside the upper plate 102, the support block 202 is fixedly connected to one side of the upper plate 102, the limiting rod 201 is fixed to the support block 202, the limiting slide plate 203 is fixedly connected to one side of the slider 105, and the limiting slide plate 203 is sleeved on the circumferential surface of the limiting rod 201.

[0048] The placement platform 301 is located at the upper end of the upper plate 102, and the placement platform 301 is fixed to the upper end of the slider 105.

[0049] The first socket 502 and the second socket 505 are both located at the upper end of the placement platform 301. The outer diameter of the plug rod 503 is smaller than the inner diameter of the first socket 502 and the second socket 505. A magnet is installed inside the plug rod 503.

[0050] In a specific embodiment of this utility model, the workbench 101 serves as the upper plate 102 of the basic support structure, supporting the placement platform 301. The output shaft of the motor 103 is fixed to the lead screw 104. The block 105 is threadedly engaged with the lead screw 104 via a nut and slides along the inner wall of the workbench 101 under the drive of the motor 103, achieving precise linear movement. The limiting rod 201 cooperates with the support block 202 to limit the movement stroke. The limiting slide plate 203 is linked with the slider 105 to ensure no deviation during movement. The cooperation between the limiting rod 201 and the limiting slide plate 203 can effectively suppress the radial movement of the slider 105. To ensure the stability of linear motion, the support block 202 enhances the rigidity of the limit rod 201, preventing deformation due to load or vibration. It is suitable for high-precision machining environments. The placement platform 301 moves synchronously with the slider 105 to support the workpiece to be transported. It is connected to the pull plate 302 through the pull rod 304. The pull rod 304 slides through the placement platform 301, allowing the clamping plate 305 to move laterally. The spring 303 provides elastic clamping force to prevent rigid clamping from damaging the workpiece surface. When the pull plate 302 is pulled manually or automatically, the opening and closing degree of the clamping plate 305 can be adjusted for quick loading and unloading of workpieces.

[0051] Please refer to Figures 1-7 for details. The upper end of the platform 301 is fixedly connected with a pad 400. There are four pads 400, and the material is rubber.

[0052] In this embodiment, the rubber pad 400 protects the workpiece, forming a closed loop from handling and positioning to damage prevention clamping, meeting the stringent requirements of the precision manufacturing field.

[0053] The working principle and usage process of this utility model are as follows: The operator places the linear guide rail or other precision workpiece to be transported on the placement platform 301, with the bottom of the workpiece in contact with the rubber pad 400 to avoid direct metal-to-metal collision. The operator manually or automatically pulls the pull plate 302, which moves the pull rod 304 and the clamping plate 305 to clamp and fix the workpiece. The spring 303 provides flexible pressure to prevent the workpiece from being deformed or damaged due to excessive clamping. The motor 103 is started, which drives the lead screw 104 to rotate. Since the slider 105 is threadedly engaged with the lead screw 104 through the nut, when the lead screw rotates, the slider moves linearly along the inner guide rail of the worktable 101. At the same time, the limiting slide plate 203 moves along the limiting rod 20 1. Sliding ensures precise and unbiased movement trajectory. Since the placement platform 301 is fixed on the slider 105, the workpiece moves synchronously with the slider. During the handling process, the workpiece contacts the rubber pad 400 to absorb mechanical vibration and prevent damage to the workpiece surface. The limit rod 201 and the support block 202 limit the movement range of the slider 105 to avoid overtravel. The motor 103 stops according to the preset program or sensor feedback. When the slider 105 reaches the target position, the pull plate 302 is released, and the spring 303 rebounds to automatically open the clamp 305, allowing the workpiece to be safely removed. The motor 103 rotates in the opposite direction, and the slider 105 drives the placement platform 301 back to the initial position, waiting for the next handling task.

[0054] The slide rod 504 is slidably embedded in the groove 501 and fixed to the pull plate 302, so that the pull of the pull plate 302 directly drives the slide rod 504 to move. After the insertion rod 503 is inserted into the insertion hole 502, it can lock the position of the slide rod 504 to prevent the clamping plate 305 from being accidentally released. The cooperation between the insertion rod 503 and the insertion hole 502 provides mechanical locking, ensuring constant clamping force during transportation and improving safety. The slide rod 504 slides in the groove 501, with a compact structure and precise guidance, avoiding jamming of the clamping mechanism. Each component can be adjusted or replaced independently to adapt to diverse processing needs.

[0055] When the workpiece is limited by the clamping plate 305, the limiting force is mainly provided by the spring 303. The use of the spring 303 to provide flexible pressure mainly avoids excessive clamping force and damage to the workpiece; however, without a secondary limiting device for locking, it is difficult to ensure the clamping stability of the equipment.

[0056] Therefore, this utility model provides multiple levels of limit travel for selection and use;

[0057] In the first stage, referring to Figure 6, one end of the slide rod 504 has a boss that slides and engages with the inner wall of 501. During the clamping operation, the operator inserts the insertion rod 503 into the second insertion hole 505, as shown in Figure 6. The insertion rod 503 limits the boss, ensuring the stability of the slide rod 504, the pull plate 302 / pull rod 304, and the clamping plate 305, and preventing displacement after clamping from affecting the clamping effect.

[0058] In the second stage, referring to Figure 7, the operator inserts the insertion rod 503 into the first insertion hole 502, as shown in Figure 7. The insertion rod 503 limits the boss, ensuring the stability of the slide rod 504, the pull plate 302 / pull rod 304 and the clamping plate 305, and ensuring that the clamping effect is not affected by displacement after clamping.

[0059] With two different limit positions, the clamping of the clamping plate 305 can be limited in two ways at different positions to ensure stable use of the equipment;

[0060] The insertion rod 503 contains a magnet, and the placement platform 301 is made of a magnetically conductive material, such as iron. When the insertion rod 503 is inserted into the first insertion hole 502 or the second insertion hole 505, it can be attracted to the placement platform 301 by the magnet, ensuring stable use and preventing slippage.

[0061] To lock the clamping position, insert the rod 503 into the socket 502 to prevent loosening during transport.

[0062] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
