Description

Technical Field

[0001] This application relates to the field of mobile platform technology, and in particular to a reading head mounting structure, a moving device, and a processing system. Background Technology

[0002] A readhead is an optical or magnetic sensor used for precision position measurement. It is usually used in conjunction with an optical or magnetic scale to achieve accurate detection of displacement or angle through encoded signals. It is widely used in machine tools, measuring equipment and other fields.

[0003] The deviation of the reading head's installation position on the moving platform from the ideal installation position will introduce systematic measurement errors (Abbe error, cosine error, etc.). These errors are often much larger than the accuracy error of the reading head itself, which will seriously reduce the performance of the entire motion system.

[0004] The reading head has a certain error range relative to the grating ruler. In actual installation, due to the accumulation of mechanical errors, it is usually necessary to manually adjust the position of the reading head to ensure that the reading head works normally.

[0005] However, the reading head is usually installed on the bottom surface of the moving platform, located between the moving platform and the base. The operating space is small, and due to the obstruction of components such as sliders and slide rails under the moving platform, it is even more difficult to adjust the position of the reading head under the moving platform. Therefore, there are problems of difficulty in adjusting the position of the reading head and low adjustment efficiency. Utility Model Content

[0006] This application provides a reading head mounting structure, a moving device, and a processing system to solve the technical problems of difficult and inefficient adjustment of the reading head position in related technologies.

[0007] In a first aspect, a reading head mounting structure is provided for mounting a reading head onto a mobile platform. The mobile platform has a mounting groove on its bottom surface, one side wall of the mounting groove is open, and the wall of the mounting groove facing the opening is the mounting surface. The reading head mounting structure includes:

[0008] A fixed block, wherein the reading head is fixed to the side of the fixed block;

[0009] The first adjustment and fixing structure includes at least two first bolts; multiple first bolts pass through the fixing block and are threaded into the mounting surface of the mounting groove, and the multiple first bolts are spaced apart in the length direction of the reading head; the working end of the reading head is lower than the bottom surface of the moving platform;

[0010] Wherein, the diameter of the mounting hole on the fixing block through which the first bolt passes is larger than the diameter of the first bolt, and when the first bolt is located in the middle of the mounting hole, there is a gap between the first bolt and the wall of the mounting hole.

[0011] In some embodiments, the mounting surface of the mounting slot is arranged near the center of the mobile platform.

[0012] In some embodiments, the mounting hole is an oblong hole, and the oblong hole is arranged vertically along its length.

[0013] In some embodiments, the reading head mounting structure further includes a second adjustment and fixing structure, the second adjustment and fixing structure comprising:

[0014] A fixing hole is formed through the surface of the mobile platform;

[0015] The second bolt passes through the fixing hole and is threadedly connected to the fixing block;

[0016] The diameter of the fixing hole is larger than the diameter of the second bolt.

[0017] In some embodiments, the fixing hole includes a countersunk hole, and the head of the second bolt is located within the fixing hole.

[0018] In some embodiments, the second adjustment and fixing structure further includes:

[0019] A push-top screw hole is provided, which is formed through the top surface of the moving platform. The push-top screw hole and the fixing hole are arranged at intervals along the length direction of the reading head.

[0020] The push-top screw hole is used for the threaded connection of the adjusting bolt, and the adjusting bolt passes through the push-top screw hole to push the fixing block.

[0021] In some embodiments, there are two push screw holes, and the fixing hole is located between the two push screw holes.

[0022] The beneficial effects of the technical solution provided in this application include:

[0023] This application provides an installation structure for a reading head. The reading head is first fixed to a fixing block, and then the fixing block is fixed to a moving platform, thereby expanding the fixed position of the reading head. This makes it convenient to fix the reading head from multiple positions, and the position of the reading head can also be adjusted by adjusting the position of the fixing block, making the installation of the reading head more flexible.

[0024] Because the bottom surface of the mobile platform has an installation groove, and the fixing block is fixed to the groove wall, and the fixing block is connected to the groove wall opposite the opening of the installation groove, it is convenient to fix the first bolt from the opening of the installation groove or even inside the installation groove and fix the fixing block to the groove wall of the installation groove. When it is necessary to tighten or loosen the first bolt to adjust the position of the fixing block and the reading head, it is also convenient to extend a wrench from the opening of the installation groove on the side of the mobile platform into the installation groove to tighten or loosen the first bolt, thereby facilitating the adjustment of the fixing block and the reading head.

[0025] Since there are at least two first bolts and multiple first bolts are arranged along the length of the reading head, the tightness of different first bolts can be controlled to adjust the degree to which the fixing block is close to the groove wall of the mounting groove at different positions. This allows for fine-tuning of the fixing block and the reading head in the horizontal plane, thereby adjusting the angular position of the reading head in the horizontal plane.

[0026] In addition, since the diameter of the mounting hole on the fixing block is larger than the diameter of the first bolt, the fixing block can move relative to the first bolt, thereby facilitating the change of the position of the fixing block at different heights, realizing the angle adjustment of the fixing block and the reading head in the vertical plane as well as the overall height adjustment.

[0027] Therefore, the mounting structure of this reading head facilitates multi-angle and multi-degree-of-freedom adjustment of the reading head in the horizontal and vertical planes. The adjustment method is convenient, not limited by the space below the moving platform, which facilitates the adjustment process and improves adjustment efficiency.

[0028] Secondly, a mobile device is provided, comprising:

[0029] Mobile platform;

[0030] A reading head is mounted on the mobile platform via the reading head mounting structure described above, and the length direction of the reading head is consistent with the sliding direction of the mobile platform.

[0031] Multiple sets of sliding components are provided. The mobile platform is slidably arranged on an external base via multiple sets of sliding components. Each sliding component includes a slide rail and multiple sliders. The slide rail is installed on the base, and the multiple sliders are all connected to the mobile platform and are slidably disposed on the slide rail.

[0032] In some embodiments, the mounting slot of the mobile platform is located between two sliders on the same slide rail.

[0033] Another embodiment of this application provides a mobile device. Since the mobile device includes the above-described reading head mounting structure, the beneficial effects of the mobile device are the same as those of the above-described reading head mounting structure, and will not be repeated here.

[0034] Thirdly, a processing system is provided, including the reading head mounting structure as described above, and / or, the moving device as described above.

[0035] Another embodiment of this application provides a processing system. Since the processing system includes the reading head mounting structure as described above, and / or the moving device as described above, the beneficial effects of the processing system are consistent with the beneficial effects of the reading head mounting structure and the moving device as described above, and will not be repeated here.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] This application provides a reading head mounting structure, a moving device, and a processing system. By creating a mounting groove with an opening on one side on the bottom surface of the moving platform, and using a fixing block and multiple first bolts to fix the reading head to the groove wall directly opposite the opening, it is convenient to reach into the mounting groove to operate the first bolts and adjust the position of the reading head, thus improving the adjustment efficiency of the reading head. This application solves the technical problems of difficult and inefficient adjustment of the reading head position in related technologies.

[0045] Reference Figures 1-4 A reading head mounting structure is provided for mounting a reading head 1 onto a mobile platform 3. The bottom surface of the mobile platform 3 has a mounting groove 31, with one side wall of the mounting groove 31 being open, meaning one side of the mounting groove 31 extends to the side of the mobile platform 3 in an open configuration. The groove wall of the mounting groove 31 directly opposite its opening serves as the mounting surface. The reading head 1 is mounted on the mounting surface.

[0046] With this configuration, since the mounting surface faces the opening of the mounting groove 31 on the side of the moving platform 3, it is convenient to extend from the side of the moving platform 3 into the mounting groove 31 to adjust the position of the reading head 1, which facilitates the adjustment operation of the reading head 1 and improves the adjustment efficiency.

[0047] Reference Figures 1-4 The reading head mounting structure includes a fixing block 2 and a first adjusting fixing structure 4. The reading head 1 is fixed to the side of the fixing block 2 by bolts, and the fixing block 2 is fixed to the mounting surface by the first adjusting fixing structure 4, ensuring that the length direction of the reading head 1 is consistent with the movement direction of the moving platform 3. After the reading head 1 is mounted on the mounting surface by the fixing block 2, the working end of the reading head 1 is lower than the bottom surface of the moving platform 3, thus avoiding the mounting groove 31 from obstructing the working end of the reading head 1.

[0048] Reference Figures 1-4 Specifically, the first adjustment and fixing structure 4 includes at least two first bolts. The plurality of first bolts pass through the fixing block 2 and are threaded into the mounting surface of the mounting groove 31, and the plurality of first bolts are spaced apart along the length of the reading head 1.

[0049] By locking the fixing block 2 to the mounting surface with multiple first bolts, the fixing block 2 and the reading head 1 can be fixed.

[0050] With this configuration, since the bottom surface of the mobile platform 3 has an installation groove 31 and the fixing block 2 is fixed to the groove wall of the installation groove 31, and the fixing block 2 is connected to the groove wall opposite the opening of the installation groove 31, it is convenient to fix the first bolt from the opening of the installation groove 31 or even inside the installation groove 31 and fix the fixing block 2 to the groove wall of the installation groove 31. When it is necessary to loosen or tighten the first bolt to adjust the position of the fixing block 2 and the reading head 1, it is also convenient to extend a wrench from the opening of the installation groove 31 on the side of the mobile platform 3 into the installation groove 31 to loosen or tighten the first bolt, thereby facilitating the adjustment of the fixing block 2 and the reading head 1.

[0051] Reference Figures 1-4 Since there are at least two first bolts and multiple first bolts are arranged along the length of the reading head 1, the tightness of different first bolts can be controlled to adjust the degree to which the fixing block 2 is close to the groove wall of the mounting groove 31 at different positions. This allows for fine-tuning of the fixing block 2 and the reading head 1 in the horizontal plane, thereby adjusting the angular position of the reading head 1 in the horizontal plane.

[0052] It should be noted that the rotation angle of reading head 1 in the horizontal plane is relatively small, around 1 degree.

[0053] Reference Figures 1-4 Furthermore, the diameter of the mounting hole 21 on the fixing block 2 for the first bolt to pass through is larger than the diameter of the first bolt. When the first bolt is located in the middle of the mounting hole 21, there is a gap between the first bolt and the hole wall of the mounting hole 21.

[0054] With this configuration, since the diameter of the mounting hole 21 on the fixing block 2 is larger than the diameter of the first bolt, the fixing block 2 can move relative to the first bolt, thereby facilitating the change of the position of the fixing block 2 at different heights, and realizing the angle adjustment of the fixing block 2 and the reading head 1 in the vertical plane as well as the overall height adjustment.

[0055] It should be noted that the rotation angle of reading head 1 in the vertical plane is relatively small, around 1 degree.

[0056] In this embodiment, there are two first bolts.

[0057] Reference Figures 1-4 The mounting surface of the mounting slot 31 is positioned close to the center of the moving platform 3. Therefore, after installation, the reading head 1 is positioned close to the center of the moving platform 3. This reduces the positional deviation of the reading head 1 caused by the load on the moving platform 3, thereby improving the accuracy of the motion system.

[0058] Among them, the mounting hole 21 is an oblong hole, and the length direction of the oblong hole is arranged vertically.

[0059] With this design, since the mounting hole 21 is an oblong hole, the adjustment stroke of the fixing block 2 in the vertical direction is greater, which makes it easier to adjust the height of the fixing block 2 and the reading head 1, and ensures that the reading head 1 is adjusted to the required position.

[0060] Reference Figures 1-4 The reading head mounting structure further includes a second adjustment and fixing structure 5, which includes a fixing hole 51 and a second bolt 52. The fixing hole 51 is formed through the surface of the moving platform 3, and the second bolt 52 passes through the fixing hole 51 and is threadedly connected to the fixing block 2. Thus, by inserting the second bolt 52 through the top surface of the moving platform 3, the fixing block 2 and the reading head 1 are further fixed to the moving platform 3, ensuring the installation stability of the reading head 1.

[0061] In this embodiment, the diameter of the fixing hole 51 is larger than the diameter of the second bolt 52.

[0062] This design allows for some leeway in the movement of the fixing block 2 in the horizontal plane, preventing the second bolt 52 from completely limiting the position of the fixing block 2.

[0063] In addition, the second bolt 52 is threadedly connected to the fixed block 2, so that the height of the reading head 1 can be changed by rotating the second bolt 52. Therefore, the height position of the reading head 1 can be adjusted on the top surface of the moving platform 3, without being constrained by the space below the moving platform 3, which facilitates the adjustment operation and improves the adjustment efficiency.

[0064] Reference Figures 1-4 Preferably, the fixing hole 51 includes a countersunk hole, and the head of the second bolt 52 is located inside the fixing hole 51.

[0065] This design hides the head of the second bolt 52 inside the fixing hole 51, avoiding interference with the components to be installed on the mobile platform 3.

[0066] The second adjustment and fixing structure 5 also includes a push-up screw hole 53. The push-up screw hole 53 is formed through the top surface of the moving platform 3, and the push-up screw hole 53 and the fixing hole 51 are arranged at intervals along the length of the reading head 1. The push-up screw hole 53 is used for threaded connection of the adjusting bolt a, and the adjusting bolt a passes through the push-up screw hole 53 to push the fixing block 2.

[0067] With this configuration, the external adjusting bolt a passes through the push-up screw hole 53 and pushes the fixing block 2, allowing it to align downwards on the top of the moving platform 3. Tightening the second bolt 52 raises the fixing block 2 upwards, thus adjusting the height of the fixing block 2 and the reading head 1 above the moving platform 3. Furthermore, since the second bolt 52 and the adjusting bolt a act on the fixing block 2 along the length of the reading head 1, combining the operation of the second bolt 52 and the adjusting bolt a allows the fixing block 2 to rotate in the vertical plane, facilitating the adjustment of the reading head 1's position.

[0068] Preferably, there are two push screw holes 53, and the fixing hole 51 is located between the two push screw holes 53. This allows for rapid adjustment of the height of both ends of the reading head 1.

[0069] The working process of this embodiment is as follows:

[0070] First, fix the reading head 1 to the fixing block 2, and then initially fix the fixing block 2 to the moving platform 3 using the second bolt 52. Next, through the opening of the mounting groove 31 on the side of the moving platform 3, extend the first bolt and operating tool into the mounting groove 31, and use multiple first bolts to fix the fixing block 2 to the mounting surface. Adjust the angle of the reading head 1 in the horizontal plane by adjusting the tightness of the multiple first bolts. Then, pass the adjusting bolt a through the push screw hole 53 to push the fixing block 2, and adjust the height of the fixing block 2 and its angle in the vertical plane in conjunction with the second bolt 52. Finally, fix the second bolt 52 and remove the adjusting bolt a to complete the fixing of the reading head 1.

[0071] This application provides an installation structure for a reading head 1. The reading head 1 is first fixed on a fixing block 2, and then the fixing block 2 is fixed on a moving platform 3, thereby expanding the fixed position of the reading head 1. This makes it convenient to fix the reading head 1 from multiple positions, and the position of the reading head 1 can also be adjusted by adjusting the position of the fixing block 2, making the installation of the reading head 1 more flexible.

[0072] Since the bottom surface of the mobile platform 3 has an installation groove 31, and the fixing block 2 is fixed to the groove wall of the installation groove 31, and the fixing block 2 is connected to the groove wall opposite the opening of the installation groove 31, it is convenient to fix the first bolt from the opening of the installation groove 31 or even inside the installation groove 31 and fix the fixing block 2 to the groove wall of the installation groove 31. When it is necessary to tighten or loosen the first bolt to adjust the position of the fixing block 2 and the reading head 1, it is also convenient to extend the wrench from the opening of the installation groove 31 on the side of the mobile platform 3 into the installation groove 31 to tighten or loosen the first bolt, thereby facilitating the adjustment of the fixing block 2 and the reading head 1.

[0073] Since there are at least two first bolts and multiple first bolts are arranged along the length of the reading head 1, the tightness of different first bolts can be controlled to adjust the degree to which the fixing block 2 is close to the groove wall of the mounting groove 31 at different positions. This allows for fine-tuning of the fixing block 2 and the reading head 1 in the horizontal plane, thereby adjusting the angular position of the reading head 1 in the horizontal plane.

[0074] In addition, since the diameter of the mounting hole 21 on the fixing block 2 is larger than the diameter of the first bolt, the fixing block 2 can move relative to the first bolt, thereby facilitating the change of the position of the fixing block 2 at different heights, and realizing the angle adjustment of the fixing block 2 and the reading head 1 in the vertical plane as well as the overall height adjustment.

[0075] Therefore, the installation structure of the reading head 1 facilitates multi-angle and multi-degree-of-freedom adjustment of the reading head 1 in the horizontal and vertical planes. The adjustment method is convenient and is not limited by the space below the moving platform 3, which facilitates the adjustment process and improves the adjustment efficiency.

[0076] Reference Figure 5 Another embodiment of this application provides a mobile device, including:

[0077] Mobile Platform 3.

[0078] The reading head 1 is mounted on the moving platform 3 via the reading head mounting structure described above, and the length direction of the reading head 1 is consistent with the sliding direction of the moving platform 3.

[0079] Multiple sets of sliding components 6 are provided. The mobile platform 3 is slidably arranged on the external base through multiple sets of sliding components 6. The sliding component 6 includes a slide rail 61 and multiple sliders 62. The slide rail 61 is installed on the base, and the multiple sliders 62 are all connected to the mobile platform 3, and the sliders 62 are slidably disposed on the slide rail 61.

[0080] Furthermore, the mounting slot 31 of the mobile platform 3 is located between two sliders 62 on the same slide rail 61. This increases the adjustment space and further facilitates the adjustment operation of the portable reading head 1.

Since the mobile device includes the above-described reading head mounting structure, the beneficial effects of the mobile device are the same as those of the above-described reading head mounting structure, and will not be repeated here.
