In order to ensure that the linear guides have high precision and long life, the precision control during the processing is extremely critical, especially in the grinding process of the outer surface. The outer surface of the linear guide needs to achieve extremely high flatness and finish, which usually relies on special grinding equipment to achieve.

[0003] In the traditional linear guide processing technology, the loading and positioning process of the linear guide mostly relies on manual operation, which has the following problems: 1. High labor intensity: Especially for linear guides that are long and heavy, manual handling is very inconvenient, which increases the labor intensity of workers.

[0004] 2. Inconvenient loading: Manual loading is not only inefficient, but also easily causes damage to the linear guide rail.

[0005] 3. Positioning difficulties: In order to ensure the parallelism between the linear guide and the linear conveying direction of the grinder mold, it is usually necessary to position it. However, the positioning devices in the prior art are often complex in structure and have poor versatility, making it difficult to adapt to linear guides of different lengths.

[0006] 4. Blockage problem: After positioning, part of the outer wall of the linear guide may be blocked by the positioning structure, resulting in the grinder being unable to complete the grinding process of the outer surface of the linear guide in one go.

[0007] In order to solve the above problems, some linear guide processing equipment with a high degree of automation has appeared on the market.

[0030] Linear guides are an important part of precision machinery and are widely used in machine tools, automation equipment, measuring instruments and other fields. In order to ensure that the linear guides have high precision and long life, the precision control during the processing is extremely critical, especially in the grinding process of the outer surface. The outer surface of the linear guide needs to achieve extremely high flatness and finish, which usually relies on special grinding equipment to achieve.

[0031] In the traditional linear guide processing technology, the loading and positioning process of the linear guide mostly relies on manual operation, which has the following problems: 1. High labor intensity: Especially for linear guides that are long and heavy, manual handling is very inconvenient, which increases the labor intensity of workers.

[0032] 2. Inconvenient loading: Manual loading is not only inefficient, but also easily causes damage to the linear guide rail.

[0033] 3. Positioning difficulties: In order to ensure the parallelism between the linear guide and the linear conveying direction of the grinder mold, it is usually necessary to position it. However, the positioning devices in the prior art are often complex in structure and have poor versatility, making it difficult to adapt to linear guides of different lengths.

[0034] 4. Blockage problem: After positioning, part of the outer wall of the linear guide may be blocked by the positioning structure, resulting in the grinder being unable to complete the grinding process of the outer surface of the linear guide in one go.

[0035] In order to solve the above problems, some linear guide processing equipment with a high degree of automation has appeared on the market. Although these equipment have improved the processing efficiency and processing accuracy to a certain extent, there are still some shortcomings in practical applications, such as low positioning accuracy, limited scope of application, high cost, etc. Therefore, the development of an automatic linear guide grinding workstation that can effectively solve the above problems has important practical significance and technical value.

[0036] For this reason, Figures 1 to 6 As shown, the automatic grinding workstation for linear guides proposed by the present invention includes a grinder 100, a support block 120, a loading module 200 and a positioning module 300, wherein the grinder 100 is provided with a workbench 110, the grinder 100 can grind the workpiece on the workbench 110, the workbench 110 is connected with a 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 manipulator 220 and a clamping assembly 230, the material rack 210 is arranged on the outside of the grinder 100 and is used to store the linear guide, the loading manipulator 220 is connected and drives the clamping assembly 230 to move between the workbench 110 and the material rack 210, and the clamping assembly 230 is suitable for being embedded and connected with the side wall of the linear guide to clamp the linear guide. The positioning module 300 is connected to the workbench 110, and the positioning module 300 includes a first driving component 310, a swing arm 320, a positioning cylinder 330 and a positioning block 340 which are connected in sequence. The first driving component 310 is connected to and drives the swing arm 320 to swing horizontally along the side toward the supporting block 120 to drive the positioning cylinder 330 to be placed above the supporting block 120. The positioning cylinder 330 is connected to and drives the positioning block 340 to move downward in a vertical direction. The positioning block 340 is provided with a positioning groove 341, and an opening 34101 for a linear guide rail to pass through is provided below the positioning groove 341. The relative groove walls of the positioning groove 341 are used to position the relative side walls of the linear guide rail. It should be noted that, by setting the feeding module 200 and the positioning module 300, the automatic feeding and precise positioning of the linear guide rail are realized, wherein the feeding module 200 can automatically take the material from the material rack 210 and accurately place the linear guide rail on the supporting block 120, thereby reducing the intervention of manual operation, reducing the labor intensity, and realizing the initial positioning of the linear guide rail. Among them, the side wall clamping of the linear guide rail not only ensures the reliability during clamping, but also reduces the risk of damage to the surface of the linear guide rail, thereby ensuring the quality of the product, and through the first driving component 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 the position accuracy of the linear guide rail, thereby improving the product quality after grinding by the grinder 100. In addition, since the positioning block 340 can leave the workbench 110 after the secondary positioning, it will not block the outer surface of the linear guide rail, so the grinder 100 can complete the grinding of the entire outer surface of the linear guide rail, further improving the convenience and efficiency of processing.

[0037] 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 which are connected by transmission. The first linear module 221, the second linear module 222 and the third linear module 223 all use motors as power, and can programmatically control the motion trajectory of the clamping assembly 230. Further, in order to improve the accuracy of the horizontal displacement of the clamping assembly 230, the accuracy of translating the linear guide rail in the material rack 210 to the workbench 110 is ensured. The first linear module 221 is connected to the clamping assembly 230 through a synchronous belt transmission 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 the processing of the grinder 100, the length direction of the linear guide rail corresponds to the length direction of the workbench 110 of the grinder 100. Therefore, when the clamping assembly 230 moves the linear guide rail from the material rack 210 to the workbench 110 of the grinder 100, it mainly translates along the width direction of the linear guide rail. In addition, in some embodiments of the present invention, referring to Figure 2 The loading module 200 includes a truss, and the loading robot 220 is arranged on the truss, which enhances the structural strength and rigidity of the entire loading device. This structural design is conducive to improving the stability and accuracy of the linear guide rail during loading and unloading, and the truss is separated from the grinder 100, which reduces the loading accuracy error caused by the processing vibration of the grinder 100.

[0038] Refer to Figure 2 and Figure 3The clamping assembly 230 includes a plurality of clamping components 231, and the plurality of clamping components 231 are arranged in a double-row array to realize a double-station design, which can realize the material taking and efficient loading of the linear guide. For example, in the application of the processing adaptation of the grinder 100, a station takes the material and moves it to the loading area of ​​the grinder 100, and can take out the processed linear guide and immediately put in the linear guide to be processed, thereby improving the overall loading efficiency. Among them, the plurality of clamping components 231 in a single row can clamp different positions of the linear guide at the same time, ensuring the stability and safety of the linear guide during the movement. Specifically, the clamping component 231 includes a clamping cylinder 2311, two first clamping blocks 2312 arranged opposite to each other, and two second clamping blocks 2313 arranged opposite to each other. The first clamping block 2312 and the second clamping block 2313 are respectively arranged on both sides of the clamping cylinder 2311. The clamping cylinder 2311 connects and drives the first clamping block 2312 and the second clamping block 2313 to clamp or release the linear guide rail together, which can increase the clamping area with the linear guide rail, improve the clamping firmness, ensure that the linear guide rail remains stable during movement, reduce the risk of linear guide rail deformation caused by uneven clamping, and improve processing quality and efficiency. In some embodiments, the clamping cylinder is a pneumatic clamping finger, and the clamping fingers of the pneumatic clamping finger are respectively directly and fixedly connected to the first clamping block and the second clamping block, directly driving the two first clamping blocks and the second clamping blocks to move toward or away from each other (not shown in the figure). In some embodiments of the present invention, such as Figure 2As shown, the driving shaft of the clamping cylinder 2311 is connected to a connecting crossbar 23111, one end of the connecting crossbar 23111 and the first clamping block 2312 are driven by a first connecting rod mechanism 2314, and the other end of the connecting crossbar 23111 and the second clamping block 2313 are driven by a second connecting rod mechanism 2315. Thus, the stroke of the first clamping block 2312 and the second clamping block 2313 can be increased, and a variety of linear guide rails of different specifications can be adapted, and the stability of the clamping process of the linear guide rail is improved, and the error caused by unstable motion is reduced. Specifically, the first connecting rod 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, the first transmission rod 23142 corresponds to the first clamping block 2312 one by one, 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 part of the first clamping block 2312, and the other end is hinged to the first connecting rod 23141. Through the cooperation of the mechanical transmission structure of the first connecting rod 23141, the first transmission rod 23142, the connecting seat 232 and the first clamping block 2312, it is ensured that the first clamping block 2312 can accurately perform the clamping and releasing actions under the action of the clamping cylinder 2311, and this precise mechanical linkage mechanism improves the reliability and durability of the overall mechanism and prolongs the service life of the equipment. It is easy to understand that the second link mechanism 2315 is symmetrically arranged with the first link mechanism 2314, so that the first clamping block 2312 and the second clamping block 2313 can act synchronously, the structure is simple, and the coordination of the clamping process and the stability of the clamping linear guide are further improved. It should be noted that the connection structure of the second link mechanism 2315 and the second clamping block 2313 can refer to the connection structure of the first link mechanism 2314 and the first clamping block 2312, and will not be described in detail here.

[0039] In addition, refer to Figure 3 In some embodiments of the present invention, the opposite side walls of the two first clamping blocks 2312 are provided with first concave-convex wall surfaces 23121 that match the side walls of the linear guide rail, and the opposite side walls of the two second clamping blocks 2313 are provided with second concave-convex wall surfaces 23131 that match the side walls of the linear guide rail. It is easy to understand that the concave-convex wall surfaces are suitable for being embedded with the side walls of the linear guide rail, which can ensure the reliability during clamping, reduce the risk of damage to the surface of the linear guide rail, ensure that the linear guide rail does not produce unnecessary displacement in the clamped state, and improve the surface quality and processing accuracy of the processed linear guide rail.

[0040] It should be noted that the positioning block 340 only needs to move downward without actively clamping the relative side walls of the linear guide rail inward to achieve the positioning of the linear guide rail. For example, the loading robot 220 places the linear guide rail on the supporting block 120 to complete the initial positioning, and then the positioning block 340 is used to perform secondary positioning of the linear guide rail.

[0041] 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 the horizontal cross-sectional area of ​​the base 121, the support portion 122 is protruded upward from the base 121, the linear guide rail is placed on the end surface of the support portion 122, and the positioning groove 341 includes a first positioning section 3411 and a second positioning section 3412 that are connected to each other, the relative groove wall of the first positioning section 3411 abuts against the relative side wall of the base 121, and the relative groove wall of the second positioning section 3412 positions the relative side wall of the linear guide rail. It is easy to understand that the first positioning section 3411 uses the base 121 as a matching reference, and the second positioning section 3412 cooperates with the side wall of the linear guide rail, so that the linear guide rail is accurately positioned on the support portion 122, ensuring the position of the linear guide rail on the support block 120. 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 inserted into the supporting block 120, the linear guide is located at a central position on the supporting block 120. Furthermore, an arc transition wall 3413 is provided between the first positioning segment 3411 and the second positioning segment 3412, which can reduce the stress concentration when the positioning block 340 contacts the linear guide, prevent the linear guide from being deformed or damaged during the positioning process, and further ensure the quality and processing accuracy of the linear guide. In addition, the arc transition wall 3413 can also improve the contact state of the linear guide during the positioning process, reduce wear, and extend the service life of the positioning block 340. In addition, in some embodiments, the base 121 is used to connect with the workbench 110, and the supporting portion 122 is integrally connected to the base 121 and is arranged at a central position of the base 121. Optionally, the width of the supporting portion 122 is smaller than the maximum width of the linear guide rail, and during the positioning block 340 positioning the linear guide rail, the groove wall of the second positioning section 3412 will not collide with the supporting portion 122. Figure 4 In addition to controlling the vertical stroke of the positioning block 340 by the positioning cylinder 330 to adapt to linear guide rails of different heights, in some embodiments of the present invention, the positioning module 300 includes a second drive assembly 350, which is connected to and drives the first drive assembly 310 to move in the vertical direction, so that the positioning module 300 can be adjusted in the vertical direction, so that the positioning block 340 can be accurately adjusted according to linear guide rails of different heights, thereby improving the accuracy and scope of application of positioning. Optionally, the second drive assembly 350 is a screw lift with a self-locking function and high safety in use.

[0042] Refer to Figure 7 In some embodiments of the present invention, there are multiple positioning modules 300, and the multiple positioning modules 300 are linearly spaced and arranged on the same side of the workbench 110, which can ensure that linear guides of different lengths can be effectively supported and positioned. This multi-point positioning method improves the stability of the positioning of the linear guide, especially for longer linear guides, which can better prevent them from bending or offsetting during the processing, thereby improving the 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. Such a layout not only ensures the stability of the linear guide during the positioning process, but also improves the economy and practicality of the entire positioning device, and also reduces the maintenance cost. Optionally, the distance between the two positioning modules 300 that are farthest apart is less than 4500mm, which can ensure the overall stability and positioning accuracy of the linear guide during the processing. Such a distance setting can not only meet the length requirements of most linear guides, but also ensure the stability of the linear guide during the positioning process, and improve the processing quality and efficiency. At the same time, this design also ensures the compactness and economy of the positioning device, which is beneficial to the space planning and cost control of the production line. Similarly, in the single-row array direction of the clamping parts 231, the distance between two adjacent clamping parts 231 is greater than 750 mm, and the distance between the two farthest clamping parts 231 is less than 2800 mm. The specified distance range between the clamping parts 231 ensures that the clamping assembly 230 can adapt to linear guides of different lengths, enhancing the versatility and flexibility of the device. In addition, the clamping point of the linear guide is optimized, which is particularly suitable for stable feeding operations on linear guides with longer lengths.
