[0017] The outstanding effects of the utility model are:

[0018] The workpiece calibration-free horizontal positioning device provided by the utility model includes a machine table and at least one reference part; the reference part is arranged on the table top of the machine table, and the first side surface of the reference part is provided with at least one convex part, the convex part extends along the direction of the reference part parallel to the machine table, and the side of the convex part away from the reference part and the table top of the machine table are respectively used to abut against the side wall and bottom wall of the workpiece. When processing the workpiece, the side wall and bottom wall of the workpiece can be directly abutted against one side of the convex reference part and the table top of the machine table respectively to be accurately positioned, thereby directly ensuring that the workpiece has excellent horizontality when placed on the machine table for processing, and there is no need to separately search for edges to determine the processing reference of the workpiece, thereby effectively shortening the processing time of the workpiece and improving production efficiency. Among them, the side wall of the workpiece is abutted against the side of the protrusion facing away from the reference part instead of directly abutting against the first side surface of the reference part, so that there is a certain accommodating gap between the side of the protrusion facing away from the reference part and the first side surface of the reference part to accommodate larger particles of dust and other foreign matter. This is equivalent to using a small plane contact method to leave a fault-tolerant space, which effectively avoids the situation where the positioning accuracy of the workpiece is affected by the presence of larger particles of dust and other foreign matter between the first side surface of the reference part and the workpiece, thereby ensuring the processing accuracy of the positioned workpiece.

[0024] 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.

The terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following describes the implementation method of the present utility model based on its overall structure.

[0026] See also Figures 1 to 3 An embodiment of the utility model discloses a workpiece 4 calibration-free horizontal positioning device, the workpiece 4 calibration-free horizontal positioning device comprises a machine table 1 and at least one reference member 2; the reference member 2 is arranged on a table 11 of the machine table 1, and a first side surface 21 of the reference member 2 is provided with at least one convex portion 3, and the convex portion 3 extends along the direction of the reference member 2 parallel to the machine table 1;

[0027] The side of the protrusion 3 facing away from the reference member 2 and the table surface 11 of the machine table 1 are used to abut against the side wall and the bottom wall of the workpiece 4 respectively.

[0028] By means of the above structure, when processing the workpiece 4, the side wall and the bottom wall of the workpiece 4 can be directly abutted against one side of the reference member 2 of the convex part 3 and the table 11 of the machine 1 respectively to be accurately positioned, so that the workpiece 4 can be directly guaranteed to have excellent levelness when placed on the machine 1 for processing, and there is no need to separately search for edges to determine the processing reference of the workpiece 4, thereby effectively shortening the processing time of the workpiece 4 and improving production efficiency. Among them, the side wall of the workpiece 4 is abutted against the side of the convex part 3 away from the reference member 2, but not directly abutted against the first side surface 21 of the reference member 2, so that there is a certain accommodation gap between the side of the convex part 3 away from the reference member 2 and the first side surface 21 of the reference member 2 to accommodate larger particles of dust and other foreign matter, which is equivalent to using a small plane contact method to leave a fault tolerance space, effectively avoiding the situation where the positioning accuracy of the workpiece 4 is affected by the presence of larger particles of dust and other foreign matter between the first side surface 21 of the reference member 2 and the workpiece 4, and ensuring the processing accuracy of the positioned workpiece 4.

[0029] See also Figures 1 to 3 Specifically, in this embodiment, there are two reference members 2, one of which is arranged at the rear edge of the table 11 of the machine 1 along the left-right direction, and the other is arranged at the right edge of the table 11 of the machine 1 along the front-back direction, so that the right end of the reference member 2 extending along the left-right direction and the rear end of the reference member 2 extending along the front-back direction abut against each other to form a preset angle of 90°, and two convex parts 3 are arranged on the first side surface 21 of the two reference members 2, and each of the convex parts 3 extends horizontally along the length direction of the corresponding reference member 2. Therefore, after the workpiece 4 is directly placed on the table 11 of the machine 1, the rear wall and the right wall of the workpiece 4 perpendicular to each other are respectively abutted against the convex parts 3 provided on the two reference members 2, so that the workpiece 4 can be accurately positioned without special edge positioning. Of course, in other embodiments, the preset angle formed between the two reference members 2 can also be set according to the actual corner size of the workpiece 4. Of course, in other embodiments, the adjacent ends of the two reference members 2 can also be set to be separated.

[0030] Specifically, in this embodiment, the two protrusions 3 provided on the first side surface 21 of the reference member 2 extending in the left-right direction both start from the left end of the reference member 2, and the two protrusions 3 provided on the first side surface 21 of the reference member 2 extending in the front-back direction both start from the front end of the reference member 2, so that when the right end of the reference member 2 extending in the left-right direction abuts against the rear end of the reference member 2 extending in the front-back direction, the ends of the two protrusions 3 separate to form a clearance space to avoid the corner of the workpiece 4. Of course, in other embodiments, the ends of the two protrusions 3 can also directly abut against each other to form a limit portion adapted to the outer side of the corner of the workpiece 4.

[0031] See also Figure 1 and Figure 2 Specifically, in this embodiment, the cross-sectional area of ​​the side of the protrusion 3 on each reference member 2 facing away from the reference member 2 is smaller than the cross-sectional area of ​​the side facing the corresponding reference member 2. Preferably, the cross-sectional shape of each protrusion 3 along the thickness direction is an isosceles trapezoid, so that there is no need to consider that dust and other debris are easily accumulated between the upward side of the protrusion 3 and the reference member 2 when the reference member 2 is installed on the machine 1.

[0032] Specifically, in this embodiment, a wear-resistant coating is provided on a side of each convex portion 3 that is away from the reference member 2, thereby effectively reducing the wear of the convex portion 3 during the process in which the workpiece 4 moves relative to the convex portion 3 and abuts against or separates from the convex portion 3. Preferably, in this embodiment, the hardness of the wear-resistant coating is HRC 55. Of course, in other embodiments, a wear-resistant coating may also be applied to the end surface of each convex portion 3 exposed outside the reference member 2, and the hardness of the wear-resistant coating may also be other values ​​not less than HRC 55.

[0033] Specifically, in the present embodiment, there is a preset gap between the side of the protrusion 3 facing the table top 11 of the machine 1 and the table top 11 of the machine 1. If there is granular dust and other debris on the table top 11 of the machine 1 (it should be understood that the granular dust and other debris include granular dust and other debris within the range visible and / or invisible to the naked eye), when the workpiece 4 gradually approaches the side of the protrusion 3 away from the reference part 2, the granular dust and other debris will be pushed into the preset gap without affecting the accurate positioning of the workpiece 4 by the protrusion 3 and the table top 11 of the machine 1, thereby eliminating the need to clean the table top 11 every time to ensure the accuracy of positioning the workpiece 4.

[0034] Specifically, in this embodiment, the protrusion 3 and the reference member 2 are integrally formed.

[0035] See also Figure 1 and Figure 3 Specifically, in this embodiment, the two reference members 2 are detachably connected to the table 11 of the machine 1 using a plurality of fasteners 5, so that after the protrusion 3 of the reference member 2 is worn, the reference member 2 can be easily replaced / repaired.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not limited to the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any changes, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
