Description

Technical Field

[0001] This invention relates to the field of linear guide processing technology, and in particular to an automatic grinding workstation for linear guides, and a feeding method for having an automatic grinding workstation for linear guides. Background Technology

[0002] Linear guides are an essential component of precision machinery, widely used in machine tools, automated equipment, and measuring instruments. To ensure high precision and long lifespan, precision control during the manufacturing process is extremely crucial, especially in the grinding of the outer surface. The outer surface of a linear guide needs to achieve extremely high flatness and smoothness, which typically relies on specialized grinding machines.

[0003] In traditional linear guide manufacturing processes, the loading and positioning of linear guides largely rely on manual operation. This method has the following problems:

[0004] 1. High labor intensity: Especially for long and heavy linear guides, manual handling is very inconvenient, which increases the labor intensity of workers.

[0005] 2. Inconvenient material loading: Manual material loading is not only inefficient, but also easily damages the linear guide rail.

[0006] 3. Positioning difficulties: In order to ensure the parallelism between the linear guide and the grinding machine's linear conveying mold direction, positioning is usually required. However, the positioning devices in the existing technology are often complex in structure, have poor versatility, and are difficult to adapt to linear guides of different lengths.

[0007] 4. Obstruction problem: The outer wall of the linear guide after positioning may be obstructed by the positioning structure, which will prevent the grinding machine from completing the grinding of the outer surface of the linear guide in one go.

[0008] To address the aforementioned issues, some highly automated linear guide processing equipment has emerged on the market. While these devices have improved processing efficiency and accuracy to some extent, they still have shortcomings in practical applications, such as low positioning accuracy, limited applicability, and high cost. Therefore, developing an automated linear guide grinding workstation that can effectively solve these problems has significant practical and technical value. Summary of the Invention

[0009] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an automatic grinding workstation for linear guides, which realizes automated feeding and precise positioning of linear guides, ensuring processing quality, and does not obstruct the outer surface of the linear guides. This allows the grinding machine to complete the grinding of the outer surface of the linear guides in one pass, improving processing efficiency and processing quality.

[0010] The present invention also proposes a feeding method for an automatic grinding workstation with linear guide rails as described above.

[0011] The automatic grinding workstation for linear guides according to the present invention includes:

[0012] Grinding machine, equipped with a worktable;

[0013] A support block, connected to the worktable, is used to support the bottom wall of the linear guide rail;

[0014] The loading module includes a material rack, a loading robot, and a clamping assembly. The material rack is located on the outside of the grinding machine and is used to store the linear guide rail. The loading robot is connected to and drives the clamping assembly to move between the worktable and the material rack. The clamping assembly is adapted to be embedded and connected to the side wall of the linear guide rail to clamp the linear guide rail.

[0015] A positioning module is connected to the workbench. The positioning module includes a first drive assembly, a swing arm, a positioning cylinder, and a positioning block connected in sequence. The first drive assembly is connected to and drives the swing arm to swing horizontally along the side facing the support block, so as to drive the positioning cylinder to be positioned above the support block. The positioning cylinder is connected to and drives the positioning block to move downward in the vertical direction. The positioning block is provided with a positioning groove, and an opening is provided below the positioning groove for the linear guide rail to pass through. The relative groove walls of the positioning groove are used to position the relative side walls of the linear guide rail.

[0016] The automatic grinding workstation for linear guides according to the present invention has at least the following beneficial effects: By setting up a feeding module and a positioning module, automated feeding and precise positioning of the linear guides are realized. The feeding module can automatically pick up the material from the material rack and accurately place the linear guides onto the support block, reducing manual intervention, lowering labor intensity, and achieving initial positioning of the linear guides. Furthermore, through the first drive assembly, the swing arm, and the positioning cylinder, the positioning block performs secondary precise positioning of the linear guides, further improving the positional accuracy of the linear guides, thereby improving the product quality after grinding. In addition, since the positioning block can leave the worktable after secondary positioning and will not obstruct the outer surface of the linear guides, the grinding machine can complete the grinding of the entire outer surface of the linear guides, further improving the convenience and efficiency of processing.

[0017] According to some embodiments of the present invention, the automatic grinding workstation for linear guides includes a clamping assembly comprising multiple clamping components arranged in a double-row array. Each clamping component includes a clamping cylinder, two opposing first clamping blocks, and two opposing second clamping blocks. The first clamping blocks and the second clamping blocks are respectively arranged on both sides of the clamping cylinder. The clamping cylinder is connected to and drives the first clamping blocks and the second clamping blocks to clamp or release the linear guide together.

[0018] According to some embodiments of the present invention, in the automatic grinding workstation for linear guide rails, the drive shaft of the clamping cylinder is connected to a connecting crossbar.

[0019] According to some embodiments of the present invention, the automatic grinding workstation for linear guide rails includes a first linkage mechanism comprising a first connecting rod and two first transmission rods. The first connecting rod is rotatably connected to the end of the connecting crossbar. The first transmission rod corresponds one-to-one with the first clamping block. The clamping assembly includes a connecting seat. The upper part of the first clamping block is hinged to the connecting seat. One end of the first transmission rod is hinged to the middle part of the first clamping block, and the other end is hinged to the first connecting rod.

[0020] According to some embodiments of the present invention, the linear guide automatic grinding workstation has a first concave-convex wall surface that mates with the side wall of the linear guide on the opposite sidewalls of the two first clamping blocks, and a second concave-convex wall surface that mates with the side wall of the linear guide on the opposite sidewalls of the two second clamping blocks.

[0021] According to some embodiments of the present invention, the automatic grinding workstation for linear guides includes a support block comprising a base and a support portion. The horizontal cross-sectional area of ​​the support portion is smaller than that of the base. The support portion protrudes upward from the base. The linear guide is placed on the end face of the support portion. The positioning groove includes a first positioning section and a second positioning section that are interconnected. The opposite groove wall of the first positioning section abuts against the opposite side wall of the base. The opposite groove wall of the second positioning section positions the opposite side wall of the linear guide.

[0022] According to some embodiments of the present invention, an automatic grinding workstation for linear guides is provided between the first positioning section and the second positioning section, with an arc transition wall.

[0023] According to some embodiments of the present invention, the linear guide automatic grinding workstation further includes a second drive component, which is connected to and drives the first drive component to move in the vertical direction.

[0024] According to some embodiments of the present invention, the automatic grinding workstation for linear guide rails has multiple positioning modules, which are arranged linearly at intervals on the same side of the worktable.

[0025] According to the feeding method of the present invention, applied to the automatic grinding workstation for linear guide rails described in the present invention, the feeding method includes the following steps: Initial feeding and positioning: First, the feeding robot drives the clamping assembly to move to the material rack, and the clamping assembly clamps the side wall of the linear guide rail; then, the feeding robot drives the clamping assembly to move above the support block, and places the linear guide rail on the support block; next, the clamping assembly releases the linear guide rail; finally, the feeding robot drives the clamping assembly away from the worktable; Secondary positioning: First, the first drive assembly drives the swing arm to swing horizontally along the side facing the worktable, driving the positioning cylinder to be positioned above the linear guide rail; then, the positioning cylinder drives the positioning block to move downward, positioning the linear guide rail in the center position of the support block; finally, the first drive assembly drives the swing arm to swing horizontally along the side away from the worktable, driving the swing arm away from the worktable.

[0026] The feeding method according to the present invention has at least the following beneficial effects: through automated feeding and positioning mechanisms, the labor intensity of operators is significantly reduced, production efficiency and safety are improved, the linear guide rail is accurately placed on the support block, and the position of the linear guide rail is further precisely adjusted through secondary positioning to make it centered on the support block, thus ensuring the positioning accuracy of the linear guide rail in the subsequent grinding process. The entire feeding and processing process is automatically completed by the workstation, which is simple to operate, reduces the skill requirements of operators, and is easy to promote and use.

[0046] Linear guides are an essential component of precision machinery, widely used in machine tools, automated equipment, and measuring instruments. To ensure high precision and long lifespan, precision control during the manufacturing process is extremely crucial, especially in the grinding of the outer surface. The outer surface of a linear guide needs to achieve extremely high flatness and smoothness, which typically relies on specialized grinding machines.

[0047] In traditional linear guide manufacturing processes, the loading and positioning of linear guides largely rely on manual operation. This method has the following problems:

[0048] 1. High labor intensity: Especially for long and heavy linear guides, manual handling is very inconvenient, which increases the labor intensity of workers.

[0049] 2. Inconvenient material loading: Manual material loading is not only inefficient, but also easily damages the linear guide rail.

[0050] 3. Positioning difficulties: In order to ensure the parallelism between the linear guide and the grinding machine's linear conveying mold direction, positioning is usually required. However, the positioning devices in the existing technology are often complex in structure, have poor versatility, and are difficult to adapt to linear guides of different lengths.

[0051] 4. Obstruction problem: The outer wall of the linear guide after positioning may be obstructed by the positioning structure, which will prevent the grinding machine from completing the grinding of the outer surface of the linear guide in one go.

[0052] To address the aforementioned issues, some highly automated linear guide processing equipment has emerged on the market. While these devices have improved processing efficiency and accuracy to some extent, they still have shortcomings in practical applications, such as low positioning accuracy, limited applicability, and high cost. Therefore, developing an automated linear guide grinding workstation that can effectively solve these problems has significant practical and technical value.

[0053] Therefore, such as Figures 1 to 6As shown, the automatic grinding workstation for linear guides proposed in this invention includes a grinding machine 100, a support block 120, a loading module 200, and a positioning module 300. The grinding machine 100 is equipped with a worktable 110, which grinds the workpiece on the worktable 110. The worktable 110 is connected to the support block 120 for supporting the bottom wall of the linear guide. The loading module 200 automatically loads the linear guide, and the positioning module 300 automatically positions the linear guide. Specifically, the loading module 200 includes a material rack 210, a loading robot 220, and a clamping assembly 230. The material rack 210 is located outside the grinding machine 100 and is used to store the linear guide. The loading robot 220 is connected to and drives the clamping assembly 230 to move between the worktable 110 and the material rack 210. The clamping assembly 230 is adapted to be embedded and connected to the side wall of the linear guide to clamp it. The positioning module 300 is connected to the workbench 110. The positioning module 300 includes a first drive assembly 310, a swing arm 320, a positioning cylinder 330, and a positioning block 340 connected in sequence. The first drive assembly 310 is connected to and drives the swing arm 320 to swing horizontally along the side facing the support block 120, so as to drive the positioning cylinder 330 to be positioned above the support block 120. The positioning cylinder 330 is connected to and drives the positioning block 340 to move downward in the vertical direction. The positioning block 340 is provided with a positioning groove 341. An opening 34101 for the linear guide rail to pass through is provided below the positioning groove 341. The relative groove wall of the positioning groove 341 is used to position the relative side wall of the linear guide rail. It should be noted that by setting up the feeding module 200 and the positioning module 300, automated feeding and precise positioning of the linear guide rail are achieved. The feeding module 200 can automatically pick up the linear guide rail from the material rack 210 and accurately place it onto the support block 120, reducing manual intervention, lowering labor intensity, and achieving initial positioning of the linear guide rail. The sidewall clamping of the linear guide rail ensures reliability during clamping and reduces the risk of surface damage, guaranteeing product quality. Furthermore, through the first drive assembly 310, the swing arm 320, and the positioning cylinder 330, the positioning block 340 performs secondary precise positioning of the linear guide rail, further improving its positional accuracy and thus enhancing the product quality after grinding by the grinding machine 100. Additionally, since the positioning block 340 can leave the worktable 110 after secondary positioning and does not obstruct the outer surface of the linear guide rail, the grinding machine 100 can complete the grinding of the entire outer surface of the linear guide rail, further improving processing convenience and efficiency.

[0054] Reference Figure 1 and Figure 2The loading robot 220 includes a first linear module 221, a second linear module 222, and a third linear module 223 connected by a transmission. All three modules are powered by motors and can be programmed to control the movement trajectory of the clamping assembly 230. Furthermore, to improve the accuracy of the horizontal movement of the clamping assembly 230 and ensure the accuracy of translating the linear guide rail in the material rack 210 to the worktable 110, the first linear module 221 is connected to the clamping assembly 230 via a synchronous belt drive structure to drive the clamping assembly 230 to move along the width direction of the linear guide rail. It is easy to understand that for grinding machine 100 processing, the length direction of the linear guide rail corresponds to the length direction of the worktable 110 of the grinding machine 100. Therefore, when the clamping assembly 230 moves from the material rack 210 to the worktable 110 of the grinding machine 100 relative to the linear guide rail, it mainly translates along the width direction of the linear guide rail. Furthermore, in some embodiments of the present invention, refer again to Figure 2 The loading module 200 includes a truss, on which the loading robot 220 is mounted, enhancing the structural strength and rigidity of the entire loading device. This structural design helps improve the stability and accuracy of the linear guide rail loading and unloading process. Furthermore, the truss is separated from the grinding machine 100, reducing loading accuracy errors caused by the processing vibration of the grinding machine 100.

[0055] Refer to Figure 2 and Figure 3The clamping assembly 230 includes multiple clamping components 231 arranged in a double-row array to achieve a dual-station design, enabling efficient material handling and loading of linear guideways. For example, in an application adapted to the grinding machine 100, one station handles material handling, moves it to the loading area of ​​the grinding machine 100, removes the finished linear guideway, and immediately places the linear guideway to be processed, improving overall loading efficiency. The multiple clamping components 231 in a single row can simultaneously clamp different positions of the linear guideway, ensuring the stability and safety of the linear guideway during movement. Specifically, the clamping component 231 includes a clamping cylinder 2311, two opposing first clamping blocks 2312, and two opposing second clamping blocks 2313. The first clamping blocks 2312 and the second clamping blocks 2313 are respectively arranged on both sides of the clamping cylinder 2311. The clamping cylinder 2311 connects to and drives the first clamping blocks 2312 and the second clamping blocks 2313 to clamp or release the linear guide rail together. This increases the clamping area with the linear guide rail, improves the clamping firmness, ensures the linear guide rail remains stable during movement, reduces the risk of linear guide rail deformation due to uneven clamping, and improves processing quality and efficiency. In some embodiments, the clamping cylinder is a pneumatic gripper, and the gripper fingers of the pneumatic gripper are directly fixedly connected to the first clamping blocks and the second clamping blocks, directly driving the two first clamping blocks and the second clamping blocks to move towards or away from each other (not shown in the figure). In some embodiments of the present invention, such as Figure 2As shown, the drive shaft of the clamping cylinder 2311 is connected to a connecting crossbar 23111. One end of the connecting crossbar 23111 is driven to the first clamping block 2312 via a first linkage mechanism 2314, and the other end of the connecting crossbar 23111 is driven to the second clamping block 2313 via a second linkage mechanism 2315. This increases the stroke of the first clamping block 2312 and the second clamping block 2313, allowing for the adaptation to more specifications of linear guides, improving the stability of the linear guide clamping process, and reducing errors caused by unstable movement. Specifically, the first linkage mechanism 2314 includes a first connecting rod 23141 and two first transmission rods 23142. The first connecting rod 23141 is rotatably connected to the end of the connecting crossbar 23111, and the first transmission rods 23142 correspond one-to-one with the first clamping blocks 2312. The clamping assembly 230 includes a connecting seat 232. The upper part of the first clamping block 2312 is hinged to the connecting seat 232, one end of the first transmission rod 23142 is hinged to the middle of the first clamping block 2312, and the other end is hinged to the first connecting rod 23141. Through the mechanical transmission structure cooperation of the first connecting rod 23141, the first transmission rods 23142, the connecting seat 232, and the first clamping block 2312, it is ensured that the first clamping block 2312 can accurately perform clamping and releasing actions under the action of the clamping cylinder 2311. This precise mechanical linkage mechanism improves the reliability and durability of the overall mechanism and extends the service life of the equipment. It is easy to understand that the second linkage mechanism 2315 is symmetrically arranged with the first linkage mechanism 2314, enabling the first clamping block 2312 and the second clamping block 2313 to move synchronously. This simple structure further improves the coordination of the clamping process and the stability of clamping the linear guide rail. It should be noted that the connection structure between the second linkage mechanism 2315 and the second clamping block 2313 can be referenced from the connection structure between the first linkage mechanism 2314 and the first clamping block 2312, and will not be described in detail here.

[0056] In addition, refer to Figure 3 In some embodiments of the present invention, the opposing sidewalls of the two first clamping blocks 2312 are each provided with a first concave-convex wall surface 23121 that mates with the sidewall of the linear guide rail, and the opposing sidewalls of the two second clamping blocks 2313 are each provided with a second concave-convex wall surface 23131 that mates with the sidewall of the linear guide rail. It is readily understood that the concave-convex wall surface is suitable for embedding into the sidewall of the linear guide rail, which ensures reliability during clamping, reduces the risk of damage to the surface of the linear guide rail, ensures that the linear guide rail does not undergo unnecessary displacement in the clamped state, and improves the surface quality and machining accuracy of the processed linear guide rail.

[0057] 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, the loading robot 220 places the linear guide rail on the support block 120 to complete the initial positioning, and then the positioning block 340 is used to perform secondary positioning of the linear guide rail.

[0058] Refer to Figures 4 to 6 In some embodiments of the present invention, the support block 120 includes a base 121 and a support portion 122. The horizontal cross-sectional area of ​​the support portion 122 is smaller than that of the base 121. The support portion 122 protrudes upward from the base 121. A linear guide rail is placed on the end face of the support portion 122. The positioning groove 341 includes a first positioning segment 3411 and a second positioning segment 3412 that are interconnected. The opposite groove wall of the first positioning segment 3411 abuts against the opposite side wall of the base 121, and the opposite groove wall of the second positioning segment 3412 positions the opposite side wall of the linear guide rail. It is readily understood that the first positioning segment 3411 uses the base 121 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 portion 122, ensuring the position of the linear guide rail on the support block 120. Optionally, the center lines of the first positioning segment 3411 and the second positioning segment 3412 are in the same vertical plane, so that after the positioning block 340 is fitted into the support block 120, the linear guide is located in the center of the support block 120. Further, an arc transition wall 3413 is provided between the first positioning segment 3411 and the second positioning segment 3412, which can reduce stress concentration when the positioning block 340 contacts the linear guide, preventing deformation or damage to the linear guide during positioning, and further ensuring the quality and machining accuracy of the linear guide. In addition, the arc transition wall 3413 can also improve the contact state of the linear guide during positioning, reduce wear, and extend the service life of the positioning block 340. Furthermore, in some embodiments, the base 121 is used to connect with the worktable 110, and the support portion 122 is integrally connected to the base 121 and located in the center of the base 121. Optionally, the width of the support portion 122 is less than the maximum width of the linear guide rail, so that during the positioning process of the positioning block 340 positioning the linear guide rail, the groove wall of the second positioning section 3412 will not collide with the support portion 122. (Refer to...) Figure 4 In addition to controlling the vertical stroke of the positioning block 340 via the positioning cylinder 330 to adapt to linear guides of different heights, in some embodiments of the present invention, the positioning module 300 includes a second drive assembly 350. The second drive assembly 350 is connected to and drives the first drive assembly 310 to move vertically, enabling the positioning module 300 to be adjusted vertically. This allows the positioning block 340 to be precisely adjusted according to linear guides of different heights, improving the accuracy and applicability of the positioning. Optionally, the second drive assembly 350 is a screw jack with a self-locking function, ensuring high safety during use.

[0059] Refer to Figure 7 In some embodiments of the present invention, there are multiple positioning modules 300, which are linearly spaced on the same side of the worktable 110. 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 800mm, which can reduce the number of positioning modules 300 while ensuring the positioning stability of the linear guide, thereby 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. Meanwhile, this design also ensures the compactness and economy of the positioning device, which is beneficial for production line space planning and cost control. Similarly, in the single-row array direction of the clamping components 231, the distance between two adjacent clamping components 231 is greater than 750mm, and the distance between the two farthest clamping components 231 is less than 2800mm. The specified range of distances between the clamping components 231 ensures that the clamping assembly 230 can adapt to linear guides of different lengths, enhancing the versatility and flexibility of the device. Furthermore, the clamping points of the linear guides are optimized, making it particularly suitable for stable feeding operations on longer linear guides.

[0060] Refer to Figure 8 The feeding method according to an embodiment of the present invention is applied to an automatic grinding workstation for linear guideways according to an embodiment of the present invention. The feeding method includes the following steps performed sequentially:

[0061] S100, Initial loading and positioning: First, the loading robot 220 drives the clamping assembly 230 to move to the material rack 210, and the clamping assembly 230 clamps the side wall of the linear guide rail; then, the loading robot 220 drives the clamping assembly 230 to move above the support block 120, and places the linear guide rail on the support block 120; next, the clamping assembly 230 releases the linear guide rail; finally, the loading robot 220 drives the clamping assembly 230 to leave the worktable 110.

[0062] S200, Secondary Positioning: First, the first drive assembly 310 drives the swing arm 320 to swing horizontally along the side facing the worktable 110, driving the positioning cylinder 330 to be positioned above the linear guide rail; then, the positioning cylinder 330 drives the positioning block 340 to move downward, positioning the linear guide rail in the center position of the support block 120; finally, the first drive assembly 310 drives the swing arm 320 to swing horizontally along the side away from the worktable 110, driving the swing arm 320 away from the worktable 110.

[0063] S300, grinding machine 100 processing, and worktable 110 are transported into grinding machine 100 for grinding processing.
