Description

Technical Field

[0001] This invention relates to the field of scale mounting technology, and more particularly to a scale mounting assembly and detector. Background Technology

[0002] Currently, optical (magnetic) gratings adopt a non-contact structure, which achieves zero mechanical hysteresis and high-precision measurement, while also having extremely strong anti-fouling ability. The optical (magnetic) grating ruler is easy to install with its own adhesive backing, and can be cut to any length.

[0003] However, once the optical (magnetic) grating ruler is attached to the equipment, its position cannot be adjusted by moving it. It is a one-time installation, and creases may be generated during the removal process, making it difficult to guarantee the reuse of the optical (magnetic) grating ruler.

[0004] Furthermore, optical (magnetic) grating rulers are relatively expensive per meter. In ultra-long applications (greater than 4 meters or when the customer specifies sections), the equipment is assembled in sections, but optical (magnetic) grating rulers can only be installed as a whole and cannot be installed in sections. During commissioning at our company, we need to attach the optical (magnetic) grating rulers before overall performance testing. When packaging and shipping, the already attached grating rulers must be discarded. New grating rulers must then be attached during on-site installation at the customer's site, thus creating unavoidable waste and increasing unnecessary costs.

[0005] Therefore, there is an urgent need to provide a grid ruler mounting assembly and detector to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a grid ruler installation assembly and detector, which facilitates the installation and adjustment of the grid ruler and improves the reusability and installation accuracy of the grid ruler.

[0007] To achieve the above objectives, the following technical solution is provided:

[0012] As an optional solution for the grid ruler mounting assembly, the mounting base is provided with a through-hole, one side wall of the through-hole is connected to the side wall of the mounting base, and the mounting rail is provided with a through-hole. The mounting rail is connected to the mounting base by fasteners passing through the through-hole and the through-hole.

[0013] As an optional solution for the grid ruler mounting assembly, a plurality of connecting slots are spaced apart on the mounting base along the first direction, and a plurality of connecting holes are spaced apart on the mounting track along the first direction, with the plurality of connecting slots and the plurality of connecting holes corresponding one-to-one.

[0014] As an optional solution for the grid ruler mounting assembly, it also includes at least two limiting protrusions extending along the first direction, with the at least two limiting protrusions spaced apart at the bottom of the mounting groove.

[0015] As an optional solution for the grid ruler mounting assembly, the mounting track has two first support legs protruding on the side near the mounting base, extending along the first direction, and the first support legs are set at an angle to the bottom of the mounting groove.

[0016] As an optional solution for the grid ruler mounting assembly, it also includes two limiting components, which are respectively disposed at the beginning and end of the mounting track, with the grid ruler located between the two limiting components.

[0017] As an optional solution for the grid ruler mounting assembly, the mounting track has a second support leg protruding on the side near the mounting base, extending along the first direction, and the second support leg is located between the two first support legs.

[0018] As an optional solution for the grid ruler mounting assembly, a check nut is also included. The fastener is a bolt. The connecting hole is located on the second support leg and communicates with the mounting space. The bolt passes through the mounting space, the connecting hole, and the connecting groove in sequence to connect with the check nut.

[0019] A detector includes a grid ruler, a reading head, and any of the grid ruler mounting components described above, wherein the grid ruler is inserted into an installation space, and the reading head is positioned opposite to the grid ruler.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The ruler mounting assembly provided by this invention has a mounting groove extending in a first direction on one side of the mounting track. The first and last ends of the mounting groove are interconnected. A snap-fit ​​portion protrudes from both opposite side walls of the mounting groove, forming an mounting space between the mounting groove and the snap-fit ​​portion. The ruler to be installed can be inserted into the mounting space from either the first or last end of the mounting track. The snap-fit ​​portion abuts against the outer surface of the ruler, achieving a stable installation of the ruler. The ruler does not require adhesive fixing and can be easily inserted and removed from the mounting space, improving the reusability of the ruler.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] To facilitate the installation and adjustment of the grating scale, and to improve its reusability and installation accuracy, this embodiment provides a grating scale mounting assembly and a detector, which are described below in conjunction with... Figures 1 to 6 The specific details of this embodiment will be described in detail. In this embodiment, the grating ruler 4 can be an optical grating ruler or a magnetic grating ruler.

[0045] Example 1

[0046] like Figures 1 to 3 As shown, the grating ruler mounting assembly includes a mounting rail 1 and a mounting base 2. A mounting groove 11 is provided on one side of the mounting rail 1, extending along a first direction with its first and last ends connected. Each of the opposite side walls of the mounting groove 11 has a protruding snap-fit ​​portion 12, forming a mounting space between the mounting groove 11 and the snap-fit ​​portion 12. The grating ruler 4 to be installed is configured to be inserted into the mounting space from either the first or last end. The mounting rail 1 is detachably connected to the mounting base 2. The internal shape of the mounting groove 11 can be designed according to the shape of the optical or magnetic grating ruler; no further restrictions are imposed here.

[0047] In short, a mounting groove 11 extending in a first direction is provided on one side of the mounting track 1. The first and last ends of the mounting groove 11 are connected. A snap-fit ​​part 12 is provided on each of the opposite side walls of the mounting groove 11. An installation space is formed between the mounting groove 11 and the snap-fit ​​part 12. The ruler 4 to be installed can be inserted into the installation space from either the first or last end of the mounting track 1. The snap-fit ​​part 12 abuts against the outer surface of the ruler 4, achieving a stable installation of the ruler 4. The ruler 4 does not need to be fixed by adhesive. The ruler 4 can be easily inserted and removed from the installation space, improving the reusability of the ruler 4. The installation position of the ruler 4 can also be adjusted by the mounting track 1, improving the installation accuracy of the ruler 4.

[0048] It can be installed in sections according to the equipment's segmentation requirements. The length of the mounting track 1 is unlimited, and it can be installed and adjusted at any position. No adhesive backing is required for fixation, eliminating problems that may arise later with adhesive-backed methods. In ultra-long applications (greater than 4 meters) or when the customer specifies segments, this ruler 4 is installed on the mounting track 1 using an insertion and removal method, allowing for non-destructive installation. The ruler 4 is reusable, avoiding unnecessary waste.

[0049] Furthermore, if Figure 7 and Figure 8 As shown, a connecting groove 21 is provided through the mounting base 2, and one side wall of the connecting groove 21 is connected to the side wall of the mounting base 2. A connecting hole 13 is provided through the mounting rail 1. The mounting rail 1 is connected to the mounting base 2 by passing a fastener 3 through the connecting hole 13 and the connecting groove 21. One side wall of the connecting groove 21 is connected to the side wall of the mounting base 2. The connection point is an insertion slot of the connecting groove 21. The mounting rail 1 can be installed in two ways: the fastener 3 can pass through the connecting groove 21 along the thickness direction of the mounting base 2 to achieve the connection between the mounting rail 1 and the mounting base 2; or the fastener 3 can be connected to the mounting rail 1 first, and then the fastener 3 can be hooked onto the mounting base 2 from the insertion slot and then locked. When it is necessary to remove the mounting rail 1, the fastener 3 does not need to be completely loosened. It is only necessary to create a gap between the mounting rail 1 and the mounting base 2 to remove the mounting rail 1 from the insertion slot of the connecting groove 21. It is convenient and quick to use.

[0050] Furthermore, multiple connecting slots 21 are spaced apart on the mounting base 2 along the first direction, and multiple connecting holes 13 are spaced apart on the mounting rail 1 along the first direction, with each connecting slot 21 corresponding to a different connecting hole 13. By increasing the number of connecting slots 21 and connecting holes 13, the connection strength between the mounting base 2 and the mounting rail 1 is further improved.

[0051] Furthermore, the grating ruler mounting assembly also includes at least two limiting protrusions 14 extending along a first direction, with the at least two limiting protrusions 14 spaced apart at the bottom of the mounting groove 11. Adding the limiting protrusions 14 reduces the distance between the limiting protrusions 14 and the locking portion 12, ensuring the grating ruler 4 is securely clamped within the mounting space. It also increases the frictional force between the limiting protrusions 14 and the grating ruler 4, preventing the grating ruler 4 from falling out of the mounting space. Specifically, the higher the protrusion of the limiting protrusion 14, the narrower the mounting space between the limiting protrusion 14 and the locking portion 12, resulting in a more stable installation of the inserted grating ruler 4. The locking portion 12 includes a first locking unit and a second locking unit disposed opposite each other on the side wall of the mounting groove 11. A window for the grating ruler 4 to transmit signals is formed between the first locking unit and the second locking unit at an interval. In other embodiments, the grating ruler 4 can also be inserted through the window, without limitation.

[0052] Furthermore, if Figures 1 to 3 As shown, the mounting track 1 has two protruding first support legs 15 extending in a first direction on the side near the mounting base 2. The first support legs 15 are set at an angle to the bottom of the mounting groove 11. When the fastener 3 is a bolt connecting the mounting track 1 and the mounting base 2, as the distance between the mounting track 1 and the mounting base 2 decreases, the first support legs 15 abut against the mounting base 2, further reducing the distance. This causes the angle between the first support legs 15 and the bottom of the mounting groove 11 to change, resulting in resistance from the first support legs 15. This causes the threads of the bolt and the nut to mesh, achieving a similar effect to a mating nut. Furthermore, the first support legs 15 and the snap-fit ​​parts 12 are integrally formed and correspond one-to-one. The change in the angle between the first support legs 15 and the bottom of the mounting groove 11 causes the first support legs 15 to drive the snap-fit ​​parts 12 to swing, reducing the distance between the first snap-fit ​​unit and the second snap-fit ​​unit, making the grid ruler 4 more securely installed.

[0053] Furthermore, if Figure 2 As shown, the ruler mounting assembly also includes two limiting components 6, which are respectively disposed at the beginning and end of the mounting track 1. The ruler 4 is located between the two limiting components 6 to prevent the ruler 4 from falling out of the mounting space. Specifically, the limiting component 6 includes a limiting fixing block 61 and a screw 62.

[0054] Furthermore, if Figure 3As shown, a second support leg 16 extending in a first direction protrudes from the side of the mounting track 1 near the mounting base 2. The second support leg 16 is located between the two first support legs 15, sharing the pressure borne by the first support legs 15. Specifically, the two first support legs 15 are located at both ends of the mounting track 1, and the second support leg 16 is located in the middle of the mounting track 1. The cross-sectional area of ​​the second support leg 16 is larger than that of the first support legs 15. Specifically, the first support legs 15 and the second support leg 16 are integrated with the mounting track 1 and are made of rubber or metal.

[0055] Furthermore, such as Figure 2 As shown, the scale mounting assembly also includes a check nut 5, a bolt 3, and a connecting hole 13 on the second support leg 16, which communicates with the mounting space. The bolt passes through the mounting space, the connecting hole 13, and the connecting groove 21 in sequence to connect with the check nut 5. The use of the check nut 5 prevents the nut from loosening due to vibration or temperature changes, thus improving the connection firmness of the scale mounting assembly.

[0056] In other embodiments, the outer wall of the fastener 3 is provided with external threads, and the connecting groove 21 includes a connected elongated channel and a circular channel. The inner wall of the circular channel is provided with internal threads, and the fastener 3 passes through the connecting hole 13 and is screwed into the circular channel of the connecting groove 21. By using internal and external threaded connections, the number of parts used is reduced, and production costs are lowered.

[0057] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a limiting step 22 is provided on the side of the mounting base 2 near the mounting rail 1, and one of the first support legs 15 abuts against the limiting step 22. Specifically, the limiting step 22 extends along a first direction and serves to limit the position of the mounting rail 1 on the mounting base 2.

[0058] like Figure 7 As shown, this embodiment also provides a detector, which includes a grid ruler 4, a reading head 7 and a grid ruler mounting assembly. The grid ruler 4 is inserted into the mounting slot 11 of the grid ruler mounting assembly, and the receiving end of the reading head 7 is arranged opposite to the grid ruler 4.

[0059] The detector provided by this invention enables stable installation of the grating ruler 4, facilitates insertion and removal of the grating ruler 4 from the installation space, improves the reusability of the grating ruler 4, and makes the position adjustment of the grating ruler 4 convenient, thereby improving the installation accuracy.

[0060] The method of using the grid ruler mounting assembly is as follows: Fix the mounting rail 1 to the corresponding equipment using multiple fasteners 3; install a limiting block 61 at the beginning of the mounting rail 1; insert a grid ruler 4 of the corresponding length into the mounting space of the mounting rail 1; and install another limiting block 61 at the end of the mounting rail 1.

[0061] Example 2

[0062] This embodiment provides a grid ruler mounting assembly. Compared with Embodiment 1, the basic structure of the mounting rail 1 provided in this embodiment is the same as that in Embodiment 1, except that the shape of the mounting rail 1 is different. This embodiment will not describe the structure that is the same as that in Embodiment 1 again.

[0063] like Figure 6 As shown, the side of the mounting track 1 away from the mounting groove 11 is a plane, and the plane fits into the mounting base 2.

[0064] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
