[0001] The utility model relates to the technical field of machine tool grating installation, in particular to a machine tool grating disassembly and installation device. Background Art

[0002] The grating of the machining center includes a grating scale and a reading head slidably mounted on the grating scale. The grating is a measurement feedback device that works on optical principles. Its measurement output signal is a digital pulse, which has the characteristics of large detection range, high detection accuracy and fast response speed.

[0003] When the machining center is in use, the choice of whether to install a grating will be made based on the need for machining accuracy. Currently, holes are usually drilled at the installation position of the machining center and the grating is installed using bolts. However, the accuracy of the holes is difficult to control. If the drilling position is inaccurate, the grating will be skewed after installation, making it inconvenient to adjust the grating position. The grating will also be regularly disassembled and inspected during subsequent use. Repeatedly loosening and tightening the bolts is time-consuming and labor-intensive, and frequent disassembly and assembly of the grating may also cause its installation connection to loosen.

[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] like Figure 1-4 As shown, a machine tool grating disassembly and installation device provided in this embodiment includes a shell 1, a front baffle 2 and a mounting block 3.

[0031] See also Figure 1 and Figure 2The shell 1 is in the shape of a long strip, which is adapted to the shape of the grating ruler. The bottom side and the front side of the shell 1 are open, and the two sides of the front side of the shell 1 are respectively provided with slots 11 extending upward. The bottom opening of the shell 1 provides a moving space for the reading head of the grating, and the grating ruler is installed into the shell 1 from the front opening of the shell 1. Support blocks 12 are respectively provided on both sides of the bottom side of the shell 1 to support the grating ruler after being installed in the shell 1. The rear side of the shell 1 is provided with a strip groove 13, and the strip groove 13 extends along the length direction of the shell 1.

[0032] The front baffle 2 is located at the front opening of the shell 1, and both ends of the front baffle 2 are slidably inserted into the slots 11 respectively. The front opening of the shell 1 can be opened or blocked by sliding the front baffle 2 up and down, so as to provide shielding for the grating ruler after installation.

[0033] See also Figure 1 , Figure 2 and Figure 4 , a first stud 31 and a plurality of second studs 32 are screwed on one side of the mounting block 3. The diameter of the first stud 31 is adapted to the width of the strip groove 13, and one end of the first stud 31 passes through the strip groove 13 and is located in the housing 1 and is provided with an abutment sheet 33. The size of the abutment sheet 33 is larger than the width of the strip groove 13. The first stud 31 is screwed into the mounting block 3 so that the rear side of the housing 1 can be clamped between the mounting block 3 and the abutment sheet 33. The plurality of second studs 32 are all screwed through the mounting block 3 for installation on the mounting hole of the machining center.

[0034] When in use, a mounting hole is punched at the mounting position of the machining center, and the mounting block 3 is fixedly installed at the specified position by the second stud 32. The first stud 31 is loosened to loosen the rear side of the shell 1, and the shell 1 can be rotated, or the first stud 31 is moved along the strip groove 13 to change the position of the shell 1, so that the shell 1 can be adjusted based on the mounting block 3, which is beneficial to prevent the grating from being skewed after installation and facilitates the adjustment of the grating position. Since the position of the shell 1 is adjustable, there is no need to be too precise when setting the hole for the second stud 32, and only the approximate position can be found, which greatly reduces the difficulty of drilling and improves the fault tolerance. After the placement position of the shell 1 is determined by tools such as a level or a measuring ruler, the first stud 31 is tightened so that the rear side of the shell 1 is clamped between the mounting block 3 and the abutment sheet 33. When the grating needs to be disassembled, the front baffle 2 can be slid open to put in or take out the grating.

[0035] like Figure 4 As shown, preferably, an embedding groove 14 is opened on the inner side of the shell 1 on the strip groove 13, and the width of the embedding groove 14 is adapted to the diameter of the abutment piece 33, so that the abutment piece 33 is accommodated in the embedding groove 14, which is conducive to ensuring that the grating scale is in flat contact with the inner side of the shell 1.

[0036] like Figure 1-Figure 3 As shown, in one embodiment, a clamping structure 4 is also included, and the clamping structure 4 includes a cover body 41, a drive plate 42 and a pressure plate 43. The cover body 41 is installed on the outer side of the front baffle 2, and the drive plate 42 is installed in the cover body 41 for transverse sliding, and one end of the drive plate 42 passes through the cover body 41. The drive plate 42 can be moved laterally by pulling the protruding end of the drive plate 42, and a plurality of arc grooves 421 are evenly distributed laterally and linearly on one side of the drive plate 42 close to the shell 1. The pressure plate 43 is located on the inner side of the front baffle 2. There are multiple push heads 431 evenly distributed on the pressure plate 43 in a horizontal linear manner. Each push head 431 slides through the front baffle 2 and is located in the cover body 41. Each push head 431 can be pushed into the corresponding arc groove 421. By pulling the drive plate 42, each push head 431 can be pushed out of the arc groove 421, and then the pressure plate 43 is pushed into the shell 1 by the push head 431. When the grating ruler is located in the shell 1, the pressure plate 43 can fully press the grating ruler to achieve the effect of fixing the grating ruler and prevent the grating ruler from shifting. It should be noted that an elastic rubber layer (not shown) is provided on one side of the pressure plate 43 close to the shell 1 to increase the friction with the grating ruler and prevent the grating ruler from being crushed.

[0037] Preferably, a plurality of springs 432 are connected between the front baffle 2 and the pressure plate 43. The springs 432 can provide an elastic force to bring the pressure plate 43 close to the front baffle 2, so that each push head 431 can always be in contact with the surface of the drive plate 42. When the drive plate 42 is pulled so that the arc groove 421 faces each push head 431, the push head 431 can be pressed into the corresponding arc groove 421, thereby loosening the grating scale for easy disassembly.

[0038] Furthermore, the portion of the driving plate 42 located inside the cover body 41 is provided with a limit block 422 to prevent the driving plate 42 from being pulled out of the cover body 41. Preferably, when the driving plate 42 is pulled outward and the limit block 422 reaches the limit position, each push head 431 will be separated from the circular arc groove 421 and abut against the plane of the driving plate 42, and when the driving plate 42 is pushed inward and the limit block 422 reaches the limit position, each push head 431 will return to the corresponding circular arc groove 421, which is conducive to letting the operator know the position state of the pressing plate 43.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features may be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the various embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
