[0002] Grating ruler is also called grating ruler displacement sensor (grating ruler sensor), which is a measurement feedback device that works based on the optical principle of grating. Grating ruler is often used in the closed-loop servo system of CNC machine tools, and can be used for the detection of linear displacement or angular displacement. Grating ruler generally needs to be fixedly installed with the help of a grating ruler bracket. For example, the existing patent with publication number CN219775242U discloses "a grating ruler bracket, including: a grating ruler, an electronic scanning module is provided on the front of the grating ruler, a connecting plate is fixedly connected to the front of the electronic scanning module, and a supporting short block is fixedly connected to the left and right sides of the grating ruler". It can be seen that what is described in the application is a common grating ruler bracket;

However, since the length of the bracket itself cannot be adjusted, the installation height of the grating scale in the vertical direction cannot be adaptively adjusted according to actual usage requirements, which reduces the use and installation flexibility of the entire grating scale bracket. For this reason, the utility model proposes a vertical grating scale bracket. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] See also Figures 1 to 4 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a vertical grating ruler bracket, including an adjustable bracket and a grating ruler 4 installed on the top of the adjustable bracket, the adjustable bracket is composed of a base frame 1, a top frame 2 and an adjustment structure 3, the top frame 2 is slidably installed on one side of the base frame 1, the adjustment structure 3 is arranged between the base frame 1 and the top frame 2, the grating ruler 4 is fixed to one side of the top of the top frame 2 by bolts, and the length of the entire bracket can be changed by sliding the top frame 2 up and down, thereby adjusting the height of the grating ruler 4 in the vertical direction;

[0020] The adjustment structure 3 includes a side seat 31, a movable frame 32, a limit clamping rod 33 and a limit clamping hole 34. Two side seats 31 are symmetrically welded and fixed on the left surface of the bottom frame 1. The movable frame 32 is slidably installed between the two side seats 31. The limit clamping rod 33 is welded and fixed on one side of the movable frame 32. A plurality of limit clamping holes 34 corresponding to the limit clamping rod 33 are formed on the surface of the top frame 2. The end of the limit clamping rod 33 penetrates into one of the limit clamping holes 34 to achieve stable limit of the top frame 2 and ensure the overall stability of the bracket. A T-shaped slider 21 is fixed to the left side of the bottom end of the top frame 2, and a T-shaped slide groove 11 corresponding to the T-shaped slider 21 is provided on the right surface of the bottom frame 1, and the T-shaped slider 21 slides in the T-shaped slide groove 11, so that the top frame 2 can slide up and down on one side of the bottom frame 1 to adjust the height of the grating ruler 4 in the vertical direction. A side slide groove 35 is provided on the inner surface of the side seat 31, and a side slider 36 is fixed to the upper and lower surfaces of the movable frame 32. The side slider 36 slides in the side slide groove 35, and the side slider 36 and one end of the side slide groove 35 are A spring 37 is also provided between the walls. Under the push of the spring 37, the movable frame 32 can always fit with the bottom frame 1, so that the limiting clamping rod 33 can be stably clamped in the limiting clamping hole 34, ensuring the overall stability of the bracket after adjustment. When the overall length of the bracket needs to be adjusted later, it is only necessary to pull the movable frame 32 sideways to make the side slider 36 move sideways with the guide slider 38, and make the spring 37 gradually compressed until the end of the limiting clamping rod 33 moves out of the limiting clamping hole 34, so that the limit on the top frame 2 can be released. The top frame 2 can be slid up and down to change the height of the grating ruler 4 in the vertical direction. When the installation height of the grating ruler 4 is adjusted to an appropriate height, the movable frame 32 is released so that the spring 37 pushes the side slider 36 back to reset, and the movable frame 32 rebounds with the limit clamping rod 33, so that the end of the limit clamping rod 33 can be inserted into the limit clamping hole 34 at other positions, and the top frame 2 can be limited again to achieve stable limiting after the bracket length is adjusted, ensuring the stable limiting of the grating ruler 4 after the height adjustment in the vertical direction is completed.

[0021] Among them, a guide slide rod 38 is fixed to the left surface of the side slide block 36, and the guide slide rod 38 passes through the inner side of the spring 37 and penetrates to the outer side of the side seat 31. Under the action of the guide slide rod 38, the spring 37 will not fall off from the inner side of the side slide groove 35, and at the same time will not affect the normal extension and contraction of the spring 37.

[0022] Among them, a rod hole connected to the side slide groove 35 is opened on the outer surface of the side seat 31, and the rod hole corresponds to the guide slide rod 38, so that the guide slide rod 38 can pass through smoothly and slide subsequently. A circular through hole is opened on the top surface of the base frame 1, and the circular through hole corresponds to the limit card rod 33, so that the limit card rod 33 can pass through smoothly.

[0023] Example 2

[0024] See also Figures 1 to 5 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, but is different in that an auxiliary positioning structure can be provided to facilitate the operator to determine whether the limit card hole 34 is aligned with the limit card rod 33 when adjusting the length of the bracket, thereby further improving the convenience of adjustment.

[0025] Specifically, it also includes an auxiliary positioning structure, which is arranged between the T-shaped slider 21 and the T-shaped slide groove 11. The auxiliary positioning structure includes a rubber seat 22, an arc-shaped protrusion 23 and an arc-shaped card groove 12. A rectangular groove is provided on one side surface of the T-shaped slider 21, and a rubber seat 22 is embedded and installed in the rectangular groove. An integrated arc-shaped protrusion 23 is provided on one side surface of the rubber seat 22. The rubber seat 22 and the arc-shaped protrusion 23 are both made of rubber material, and elastic deformation will occur when squeezed. The rubber seat 22 is a hollow structure, so that the arc-shaped protrusion 23 has sufficient deformation space when squeezed. The inner wall of the T-shaped slide groove 11 is evenly provided with There are multiple arc-shaped grooves 12 corresponding to the arc-shaped protrusions 23, and the arc-shaped protrusions 23 are embedded in one of the arc-shaped grooves 12. The arc-shaped protrusions 23 will be squeezed and elastically deformed during the sliding process of the T-shaped slider 21, and will be continuously squeezed into other arc-shaped grooves 12. Because the distribution spacing of the arc-shaped grooves 12 corresponds to the distribution spacing of the limit holes 34, when the arc-shaped protrusions 23 are squeezed into an arc-shaped groove 12, there will be a limit hole 34 aligned with the limit rod 33, which is convenient for the operator to judge whether the limit hole 34 is aligned with the limit rod 33 during the process of sliding the top frame 2 up and down, further improving the convenience of adjustment.

[0026] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
