First, since the operator needs to rely on experience to judge the distance between the grinding head and the workpiece, it is easy to cause inaccurate control of the grinding distance, thereby affecting the grinding effect. Second, when using a pneumatic grinder, the operator cannot intuitively understand the rotation speed of the grinding head, which may cause excessive wear or insufficient wear.
[0005] Therefore, the prior art needs to be further improved and enhanced. Utility Model Content

[0018] 1. The present application provides an easy-to-use digital display pneumatic grinder, which improves the stability and accuracy of the grinder during the grinding process by setting a display component and a positioning component. Among them, through the setting of a scanning head, the distance between the grinding head and the object to be grinded can be scanned in real time, so that the user can make height adjustments according to the value displayed on the display component. Not only can newcomers with less operating experience perform grinding more accurately, but it can also optimize and greatly improve work efficiency, ensuring that the grinding work is carried out more accurately and quickly.
[0019] 2. As a preferred embodiment of the present application, the present application can provide a placement position for the scanning head by setting an extension plate and a mounting seat, and the setting of the extension plate can ensure a certain distance between the scanning head and the grinding head, so as to reduce the impact of dust generated by grinding on the scanning head.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present application.

Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
[0035] like Figures 1 to 3As shown, the present application provides an easy-to-use digital display pneumatic grinder, which includes a grinder body 10, a display component 20 and a positioning component 30. A grinding head 11 is provided at the head end of the grinder body 10, and a display component 20 is provided at the tail end. The positioning component 30 includes a positioning seat 31 and a scanning head 32. The positioning seat 31 is provided on one side of the grinding head 11, and the scanning head 32 is provided on the positioning seat 31. The display component 20 is connected to the grinding head 11 and the scanning head 32.
[0036] Among them, Figure 1 As shown, for the structure of the grinder, it can adopt a handheld pistol-type structure, of course, it can also adopt a pen-type structure. In order to facilitate the description of the structure here, this application takes the pen-type structure similar to patent CN210388840U as the main body to describe the structure.
[0037] The display component 20 can be used as a display screen that does not need to be too large and is equipped with buttons for operation to switch the displayed data.
[0038] It can be understood that the structure of the scanning head 32 can be used to scan the distance between it and the object being polished. In order to facilitate the user to have a clearer understanding of the data, the PLC or single-chip microcomputer program can be used to subtract the distance between the scanning end and the polishing end of the scanning head 32 and the polishing head 11 in the vertical direction when the display component 20 obtains a specific value. In other words, the value displayed by the display component 20 is the distance between the polishing head 11 and the object being polished, and because the polishing head 11 used during polishing often has a standard model size and length, when replacing the polishing head 11, the distance display of the display component 20 can be switched directly by pressing a button, or the distance display can be updated directly by connecting the display component 20 to an external computer, which can improve the applicable scenarios.
[0039] Of course, this type of program and scanning distance algorithm are frequently used solutions in the prior art. Therefore, this application only uses it as an optimal solution to achieve the purpose of this application. No specific description of this algorithm and program is given here. In addition, for other ranging methods that can achieve this effect, this application can also adopt them when appropriate.
[0040] In addition, if Figure 1 and Figure 2 As shown, with regard to the positional relationship between the grinding head 11 and the scanning head 32, in order to reduce the wear of the grinding object on the scanning head 32 and the influence of the debris generated by grinding on the scanning head 32, the grinding head 11 is closer to the grinding object in height, and there is a certain distance between them in the horizontal direction.
[0041] As a preferred embodiment of the present application, the grinder body 10 also includes an extension plate 12 and a mounting seat 13. The mounting seat 13 is arranged at the head end of the grinder body 10 and is connected to the grinding head 11. One end of the extension plate 12 is rotatably arranged on the mounting seat 13, and the other end is provided with a scanning head 32.
[0042] like Figure 1 As shown, the mounting seat 13 is a cone-like structure, and the end with a smaller diameter is used to mount the grinding head 11, wrap the grinding head 11, and Figure 1 As shown, a rotation groove 14 is provided at the outer edge of the mounting seat 13 , and a rotation ring is provided at one end of the extension plate 12 connected to the mounting seat 13 , and the rotation ring is rotatably connected to the rotation groove 14 .
[0043] It is understandable that the rotational connection between the extension plate 12 and the mounting seat 13 can facilitate timely adjustment of the position of the scanning head 32 relative to the grinding head 11 during use, so that grinding can be performed at various angles when grinding the surface of the object to be ground.
[0044] Specifically, when in use, the scanning head 32 should be rotated to the front of the grinding path, that is, on the grinding route, the scanning head 32 is in front of the grinding head 11, and the undulating state of the grinding object in front is first scanned by the scanning head 32, so that the user can observe the distance between the grinding head 11 and the grinding object from the display component 20, and then manually adjust the distance between the grinding head 11 and the grinding object. During the movement, if the distance display has not changed, there is no need to change it. If the distance becomes smaller, it means that the grinding object has a bulge here, and the grinding head 11 can be manually controlled to press down to perform detailed grinding here until the distance display returns to its original position to ensure the flatness of the grinding.
[0045] Of course, it should be noted that although there is a certain gap between the grinding head 11 and the scanning head 32, this gap should not be too large, so as to avoid the problem of the scanning area being too far away from the grinding head 11 due to the large gap, which will affect the effect of the grinding head 11 after adjustment. Try to make the area scanned by the scanning head 32 and the area polished by the grinding head 11 have a boundary or overlap.
[0046] Furthermore, in order to avoid the scanning head 32 and the grinding head 11 being too close and affecting each other, a partition 33 can be set between the scanning head 32 and the grinding head 11, and the partition 33 can be detachably connected to the extension plate 12, so as to block the influence of dust and the like on the scanning head 32 through the partition 33.
[0047] In a preferred embodiment, Figure 1As shown, the display assembly 20 further includes a rotation speed detection sensor 35 , which is disposed inside the grinding head 11 and connected to the display assembly 20 .
[0048] It is understandable that pneumatic grinders often use gas to drive the pneumatic motor to rotate, which in turn drives the grinding head 11 to rotate. The present application sets a speed detection sensor 35 inside the grinding head 11 to implement the judgment of the speed data, so as to increase the speed in the thicker part to improve the efficiency, and reduce the speed in the nearly flat part to reduce the grinding amount, thereby further ensuring the flatness of the grinding and making it more convenient to use; of course, these grinding data can also be displayed on the display component 20.
[0049] Among them, Figure 1 As shown, the display component 20 includes a display screen 21 and an operation panel 22. The display screen 21 displays the rotation speed and the distance data between the grinding head 11 and the object to be grinded. The setting of the operation panel 22 can be used for switching the distance measurement after replacing the grinding head 11 as mentioned above. On the other hand, since the handheld grinder itself is small in size, the amount of data displayed on the display screen 21 is limited. Therefore, the distance data and speed data can be switched and observed through the operation panel 22.
[0050] In a specific implementation, the scanning head 32 includes a laser distance measuring component, which is rotatably connected to the positioning seat 31 , and the positioning assembly 30 also includes an angle sensor, which is rotatably connected to the positioning seat 31 .
[0051] It can be understood that by setting up an angle sensor, the inclination angle of the grinding head 11 relative to the plane of the object being ground during grinding can be determined, and by setting a scanning head 32 rotatably connected between the positioning seat 31, the angle of the scanning head 32 can be adjusted, which is convenient for grinding inclined objects, and distance detection can also be performed, further ensuring the flatness and convenience of grinding.
[0052] As a preferred embodiment of the present application, the positioning assembly 30 further includes an adjustable auxiliary positioning plate 34 , which is connected to the side wall of the grinding head 11 and is detachably connected to the grinding head 11 .
[0053] As for the structure of the auxiliary positioning plate, it can adopt an L-shaped structure, such as Figure 3 As shown, when grinding the edge of the object to be grinded on the flat plate, it is often necessary to grind out a bevel or an uneven structure, so an adjustable auxiliary positioning plate 34 is provided to drag the bottom of the object to be grinded through the adjustable auxiliary positioning plate 34 during grinding, so as to ensure the flatness of grinding, and in conjunction with the structure of the scanning head 32, it can grind the uneven structure, further ensuring the accuracy of grinding.
[0054] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.
[0055] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
