[0032] Specifically, such as Figure 1-Figure 3 As shown, the carrier plate 1 is used to place the parts to be positioned. The shape of the carrier plate 1 can be any shape, such as a rectangle, square or polygon. In addition, the size of the carrier plate 1 is not specifically limited here and can be set according to the size of the parts to be positioned that need to be processed. The positioning component 2 is set on the carrier surface 11. The positioning component 2 includes at least two positioning surfaces 21. The two positioning surfaces 21 can form an L-shape or other shape suitable for the parts to be positioned. The two positioning surfaces 21 can be connected or spaced apart. The two positioning surfaces 21 can be respectively set corresponding to the two adjacent edges of the carrier plate 1, and the extension direction of each positioning surface 21 is parallel to the edge of the carrier plate 1 corresponding to it.

[0033] A fixing assembly 3 is provided opposite each positioning surface 21. Multiple fixing assemblies 3 and the positioning assembly 2 enclose a receiving space 4. Each edge of the supporting plate 1 may correspond to one fixing assembly 3 or multiple fixing assemblies 3. Each fixing assembly 3 includes a first adjusting member 31 and a second adjusting member 33. The first adjusting member 31 and the second adjusting member 33 may be hydraulic telescopic rods, pneumatic telescopic rods, or threaded rods. The clamping portion 32 of the fixing assembly 3 can be adjusted by the telescopic adjustment of the first adjusting member 31 so that it can slide relative to the supporting surface 11, so that it can move away from or approach the corresponding positioning surface 21. Each clamping portion 32 can be adjusted by one first adjusting member 31 or multiple first adjusting members 31. Each fixing assembly 3 includes a holding portion 34. The holding portion 34 can be a plate-shaped structure, and the holding portion 34 can be adjusted by the second adjusting member 33 in a direction perpendicular to the supporting surface 11 to move closer to or away from the supporting surface 11. Each holding portion 34 can be adjusted by one second adjusting member 33 or multiple second adjusting members 33.

[0034] The present disclosure provides a positioning tool and an engraving machine, wherein the positioning tool includes a positioning component 2 and a fixing component 3. During actual operation, the operator first preliminarily places the part to be positioned on the bearing surface 11 and fits it to the positioning surface 21 to achieve preliminary positioning. Then, the clamping portion 32 opposite to each positioning surface 21 is adjusted by the first adjusting member 31 so that it slides relative to the bearing surface 11, thereby approaching the positioning surface 21 and cooperating with it to clamp the edges of the part to be positioned. Subsequently, according to the specific thickness of the part to be positioned, the pressing portion 34 is adjusted using the second adjusting member 33 so that it approaches the bearing surface 11 in a direction perpendicular to the bearing surface 11, thereby firmly pressing the part to be positioned on the bearing surface 11. The positioning tool can adapt to parts to be positioned of different sizes, can quickly position the parts to be positioned to the same position, and can clamp the parts to be positioned from multiple directions.

[0035] In some embodiments, the first adjusting member 31 includes: a first adjusting seat 311, which is arranged on the bearing surface 11; a first adjusting rod 312, which extends in a direction parallel to the bearing surface 11, one end of which is screwed with the first adjusting seat 311, and the other end is connected to the clamping portion 32; the second adjusting member 33 includes: a second adjusting seat 331, which is arranged on the bearing surface 11; a second adjusting rod 332, which extends in a direction perpendicular to the bearing surface 11, one end of which is screwed with the second adjusting seat 331, and the other end is connected to the holding portion 34.

[0036] Specifically, such as Figure 1-Figure 3As shown, the first adjustment seat 311 can be an L-shaped base, which is arranged on the bearing plate 1. The first adjustment rod 312 is parallel to the bearing surface 11, and one end of the first adjustment rod 312 is connected to the first adjustment seat 311 via a thread. Its position relative to the adjustment seat can be changed by rotating the adjustment rod, and the other end is connected to the clamping portion 32. The second adjustment seat 331 can be an L-shaped base higher than the first adjustment seat 311, which is arranged on the bearing plate 1. The second adjustment rod 332 is perpendicular to the bearing surface 11, and one end can be connected to the second adjustment seat 331 via a thread. The other end of the second adjustment rod 332 is connected to the holding portion 34. Adjusting the second adjustment rod 332 will change the height of the holding portion 34 relative to the bearing surface 11. By adjusting the clamping portion 32 and the holding portion 34 by the first adjustment member 31 and the second adjustment member 33, multi-directional positioning and clamping of the positioning member can be achieved. In addition, since the positioning fixture is provided with a holding portion 34, it can not only position and fix hard parts to be positioned, but also position and fix soft parts to be positioned, so as to facilitate engraving thereof.

[0037] In some embodiments, it also includes: a fixed beam 5, which is arranged on the second adjustment seat 331, and its extension direction is parallel to the extension direction of the holding portion 34; a connecting portion 6, a plurality of connecting portions 6 are arranged at intervals along the extension direction of the fixed beam 5; and an elastic member 7, which can be extended and retracted in a direction perpendicular to the bearing surface 11, one end of which is connected to the connecting portion 6, and the other end is connected to the holding portion 34.

[0038] Specifically, such as Figure 1-Figure 3 As shown, the second adjustment seat 331 is provided with a fixed beam 5, which can be a plate-like structure or a columnar structure. The fixed beam 5 is provided with a plurality of connecting parts 6, which can be holes for hooking the elastic member 7. Each fixed beam 5 can be provided with a plurality of elastic members 7, which extend and retract in a direction perpendicular to the bearing surface 11, and the end of the elastic member 7 opposite to the fixed beam 5 is connected to the holding portion 34. The magnitude of the holding force can be adjusted by increasing or decreasing the number of elastic members 7. The arrangement of multiple elastic members 7 can also provide uniformly distributed pressure. The flexible holding achieved by the elastic member 7 can better adapt to workpieces of different shapes and sizes, especially when processing irregular shapes or soft materials, and can effectively avoid crushing or deformation. The elastic member 7 can be a spring, a rubber pad, etc.

[0039] In some embodiments, the positioning assembly 2 further includes: a holding portion 34 , which is offset from the positioning surface 21 in the thickness direction of the supporting plate 1 , and which can be moved closer to or away from the supporting surface 11 in a direction perpendicular to the supporting surface 11 through a second adjusting member 33 .

[0040] Specifically, such as Figure 1-Figure 3As shown, in order to make the part to be positioned close to the bearing surface 11 and to make the part to be positioned receive a uniform pressing force, the positioning assembly 2 is further provided with a pressing portion 34. The pressing portion 34 is located in the thickness direction of the bearing plate 1 and is staggered with respect to the positioning surface 21. That is, the pressing portion 34 and the positioning surface 21 are not on the same plane, but are staggered with each other to ensure that the pressing portion 34 can effectively apply pressure. The pressing portion 34 can be moved in a direction perpendicular to the bearing surface 11 by the second adjusting member 33, that is, the pressing portion 34 can be close to or away from the bearing surface 11. This adjustment mechanism allows the pressing portion 34 to be adjusted to a suitable position as needed to apply an appropriate pressing force. The pressing portion 34 can be a plane or a component with a certain shape, and the second adjusting member 33 can be a screw, a handle or other form of adjusting device, and the position of the pressing portion 34 can be adjusted by rotation or other operating methods. For example, the adjustment method of the second adjusting member 33 can utilize a threaded rod in combination with a nut, and the position of the pressing portion 34 can be adjusted by rotating the nut.

[0041] In some embodiments, it also includes: a first mounting portion 8, a plurality of first mounting portions 8 are arranged at intervals on the bearing surface 11 along the extension direction of each positioning surface 21, and each first mounting portion 8 is used to install the first adjustment seat 311; a second mounting portion 9, a plurality of second mounting portions 9 are arranged at intervals on the bearing surface 11 along the extension direction of each positioning surface 21, and each second mounting portion 9 is used to install the second adjustment seat 331.

[0042] Specifically, such as Figure 2 As shown, the first mounting portion 8 may include one or more screw holes, each of which provides a mounting position for the first adjustment seat 311. The first adjustment seat 311 is detachably connected to the first mounting portion 8 by bolts, and the operator can install the position of the first adjustment seat 311 according to actual needs. The second mounting portion 9 may include one or more screw holes, each of which provides a mounting position for the second adjustment seat 331. The second adjustment seat 331 is detachably connected to the second mounting portion 9 by bolts, and the operator can install the position of the second adjustment seat 331 according to actual needs. By providing screw holes on the first mounting portion 8 and the second mounting portion 9, and allowing the first adjustment seat 311 and the second adjustment seat 331 to be detachably connected by bolts, this design not only improves the flexibility and adjustability of the system, but also greatly enhances the convenience of installation and maintenance.

[0043] In some embodiments, the first adjustment rod 312 and the second adjustment rod 332 are telescopic rods; the first driving member, whose driving end is connected to the first adjustment rod 312, is used to control the telescopic movement of the first adjustment rod 312; the second driving member, whose driving end is connected to the second adjustment rod 332, is used to control the telescopic movement of the second adjustment rod 332.

[0044] Specifically, the first adjusting rod 312 and the second adjusting rod 332 are telescopic rods (not shown in the figure), which can be telescopic in their length direction. The telescopic rod may include multiple sleeves, which are slidably connected. The driving end of the first driving member is connected to the first adjusting rod 312 for controlling the telescopic movement of the first adjusting rod 312. The first driving member can be an electric motor, a hydraulic cylinder, a pneumatic cylinder or other forms of driving devices. The driving end of the second driving member is connected to the second adjusting rod 332 for controlling the telescopic movement of the second adjusting rod 332. The second driving member can also be an electric motor, a hydraulic cylinder or a pneumatic cylinder, etc. The telescopic position of the telescopic rod can be accurately controlled by the driving member to ensure the accuracy of positioning, and automatic control can be achieved, reducing manual operation and improving efficiency.

[0045] In some embodiments, the present invention further includes a buffer member, wherein the positioning surface 21, the side of the clamping portion 32 in contact with the part to be positioned, and the side of the pressing portion 34 in contact with the part to be positioned are provided with a buffer member.

[0046] Specifically, to improve the effectiveness of positioning assembly 2 and protect the part to be positioned, buffers (not shown) can be provided on positioning surface 21, the side of clamping portion 32 that contacts the part to be positioned, and the side of pressing portion 34 that contacts the part to be positioned. Buffers are typically made of materials with a certain degree of elasticity and wear resistance, including but not limited to rubber, polyurethane (PU), and silicone. The buffers can be secured to the contact surfaces using adhesives, snaps, or other means to ensure they do not fall off during use.

[0047] In some embodiments, the system further includes: a control component connected to the first driving member and the second driving member, for sequentially controlling the first driving member and the second driving member.

[0048] Specifically, the control component is connected to the first drive member and the second drive member by signal, and the signal connection here can be a wireless connection or a wired connection. The control component can control the first drive member and the second drive member in sequence, such as: the first drive member first controls the extension and contraction of the first adjustment rod 312, so that the clamping portion 32 clamps the to-be-positioned member in a direction parallel to the bearing surface 11, and then controls the extension and contraction of the second adjustment rod 332, so that the holding portion 34 holds the to-be-positioned member in a direction perpendicular to the bearing surface 11. In addition, the control component can also control the first drive member and the second drive member at the same time, and control the extension and contraction of the first adjustment rod 312 and the second adjustment rod 332 at the same time. By setting the control component, automation can be achieved, manual operation can be reduced, and efficiency can be improved.

[0051] The second aspect of the present application provides an engraving machine, which includes an operating table. The size of the operating table is expected to be set according to the needs of the production line. The operating table includes a positioning tool. The number of positioning tools can be one or more. Multiple positioning tools can work at the same time. The number of positioning work is not limited here. The positioning tool includes a positioning component 2 and a fixing component 3. During the actual operation, the operator first places the part to be positioned on the bearing surface 11 and fits it to the positioning surface 21 to achieve preliminary positioning. Then, the clamping portion 32 opposite to each positioning surface 21 is adjusted by the first adjusting member 31 so that it slides relative to the bearing surface 11, thereby approaching the positioning surface 21 and cooperating with it to clamp the edges of the part to be positioned. Subsequently, according to the specific thickness of the part to be positioned, the pressing portion 34 is adjusted using the second adjusting member 33 so that it approaches the bearing surface 11 in a direction perpendicular to the bearing surface 11, thereby firmly pressing the part to be positioned on the bearing surface 11. The engraving machine can adapt to parts to be positioned of different sizes, can quickly position the parts to be positioned to the same position, and can clamp the parts to be positioned from multiple directions.

[0052] In some embodiments, the system further comprises: a cutting device for cutting the supporting surface 11 of the supporting plate 1 at a preset angle to compensate for the unevenness of the operating table.

[0053] Specifically, since the operating table of the engraving machine is relatively rough, the engraving machine also includes a cutting device for cutting the carrier plate 1 in a direction parallel to the bearing surface 11, so that the carrier plate 1 can compensate for the unevenness of the operating table. The unevenness here includes but is not limited to: the operating table has local ups and downs; the operating table has a certain inclination angle relative to the reference plane. The cutting device includes one or more cutting tools, which can cut the carrier plate 1 at a precise angle. When cutting, first measure the unevenness of the operating table and determine the angle that needs to be compensated. According to the measurement results, set the cutting angle of the cutting tool to ensure that the cutting angle meets the compensation requirements. Fix the carrier plate 1 on the operating table, start the cutting device for cutting, and install the fixing component 3 after cutting is completed. By setting the cutting device, the unevenness of the operating table can be effectively compensated, ensuring that the carrier plate 1 remains flat during installation or use.
