[0002] A grinding machine is a common device used to sharpen various knives and tools. It is also used for grinding, deburring and cleaning ordinary small parts. It is mainly composed of a base, a grinding wheel, a motor (or other power source), a bracket, a protective cover and a water feeder. It can be divided into hand-held grinders, vertical grinders, suspended grinders, desktop grinders, etc., and can be used to grind objects of different materials such as metal, wood, stone and plastic.
[0003] When the product is being processed, the speed will be faster at a distance from the grinding wheel. However, in actual processing, such as taps and screws, the sizes may be long or short, thick or thin. If the product is processed directly according to the set length or diameter, when grinding the end or surface, if it is long or directly large, or there is a bulge on the surface, the external drive mechanism drives the product directly close to the grinding wheel or the grinding mechanism directly close to the workpiece, which may cause the problem of collision with the grinding wheel. The current grinding mechanism needs to manually position the workpiece, which will increase the workload of the construction personnel and reduce the production efficiency.

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] See also Figures 1 to 4 In an embodiment of the utility model, a grinding mechanism includes a linear module 1, a mounting frame 2 is provided on the slide of the linear module 1, a grinding wheel 3 rotatably connected to the mounting frame 2 is provided on the mounting frame 2, a driving device 4 for driving the grinding wheel 3 to rotate is provided on the mounting frame 2, a positioning component 5 for positioning the product to prevent it from hitting the grinding wheel 3 is provided on one side of the grinding wheel 3, the positioning component 5 includes a fixed seat 50 arranged on the mounting frame 2, a sliding frame 51 slidably matched with the fixed seat 50 is provided on the fixed seat 50, a detection probe 6 is provided at the front end of the sliding frame 51, and a driving member for driving the sliding frame 51 to move so that the detection probe 6 moves to the front end or side of the grinding wheel 3 product for positioning is provided on the fixed seat 50; in the present application, the driving member can be a cylinder 52, or it can be a mechanism such as an electric push rod to drive the sliding frame 51 to move.
[0026] When processing the workpiece, the front end face and side face of the workpiece may be irregular. If positioning is not performed, there is a high possibility of collision with the grinding wheel 3. For example, in a batch of products, each product may have some errors in the production process, resulting in long and short products. If they are all debugged according to the ideal values, when processing the front end face of the workpiece, the external drive mechanism directly moves the product to the grinding wheel 3 for grinding. When encountering a relatively long product, it will directly collide with the grinding wheel 3; and by setting the detection probe 6, the external drive mechanism can first drive the workpiece to contact the probe for positioning, find the reference point, and then use the control system to position it, calculate the length of the workpiece, and then drive the workpiece by the external drive mechanism to run quickly to the grinding wheel 3, and then process the end face. In this way, there will be no problem of collision with the grinding wheel 3. At the same time, the workpiece can be automatically positioned without the need for staff to find the reference point, thereby improving production efficiency and reducing the workload of staff.
[0027] Similarly, the same method is adopted when processing the side of the workpiece, which will not be repeated here.
[0028] Furthermore, the fixed seat 50 is also provided with an adjustment seat 53 rotatably connected thereto, and the fixed seat 50 is provided with a plurality of arc-shaped adjustment holes 54. The adjustment seat 53 is fixed by locking it into the adjustment hole 54 with provided screws, and the sliding frame 51 is provided on the adjustment seat 53 and rotatably connected thereto. By setting the sliding frame 51 on the adjustment seat 53, the angle of the sliding frame 51 can be easily adjusted, and then the angle of the detection probe 6 can be adjusted, so that the staff can facilitate debugging.
[0029] Furthermore, a first limit block 55 is provided on the adjustment seat 53, and the front and rear ends of the sliding frame 51 are provided with second limit blocks 56 that cooperate with the first limit block 55 to adjust the distance and retraction position of the detection probe 6. During debugging, the staff can set the position of the second limit block 56 according to needs to adjust the extension and retraction position of the detection probe 6.
[0030] Furthermore, a linear grating 7 is provided on the side of the slide of the linear module 1. By providing the linear grating 7, the running distance of the linear module 1 can be accurately read, so that the grinding wheel 3 can be more accurate when working, and the problem of over-grinding or under-grinding can be prevented.
[0031] Furthermore, an outer cover 8 for covering the linear grating 7 is provided on the side of the slide of the linear module 1 .
