[0001] The utility model relates to tool processing, in particular to a tool installation and positioning device for a grinding machine. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones and sanding belts and free abrasives for processing. When using a grinder, a tool mounting and positioning device is required to enable the tool to be used for processing.

[0003] In existing tool mounting and positioning devices, upper and lower mounting plates are typically used to press and secure the tool through mounting holes. This makes it difficult to secure tools of different sizes and reduces versatility. Furthermore, the tool fixings are prone to loosening, resulting in low stability and impacting tool safety. A tool mounting and positioning device for a grinding machine is urgently needed to address these issues. Utility Model Content

[0008] A pair of convex grooves are symmetrically provided on the top of the mounting seat, and a pair of convex blocks matching the convex grooves are provided at positions corresponding to the convex grooves on the bottom of the movable plate. Multiple first threaded holes connected to the adjacent convex grooves are provided on the opposite side walls of the mounting seat, and stop bolts for tightening the side walls of the convex blocks are provided inside the multiple first threaded holes.

[0009] Furthermore, the stop bolt includes a screw head and a stud, the stud is arranged at the end of the screw head, the stud is connected to the first threaded hole by a thread, a guide groove is horizontally opened on the side of the convex block close to the first threaded hole, and a guide column matching the guide groove is provided on the end of the stud away from the screw head.

[0010] Furthermore, the diameter of the screw head is larger than the diameter of the stud, the diameter of the stud is larger than the diameter of the guide post, and the diameter of the guide post is equal to the height of the guide groove.

[0011] Furthermore, a plurality of marking lines are provided on the top of the mounting seat and are located directly above the stop bolts, and the marking lines correspond to the stop bolts one by one.

[0025] like Figure 1 As shown, the utility model provides a technical solution: a tool installation and positioning device for a grinding machine, comprising:

[0026] A mounting base 1, a fixed plate 2 is provided on one side of the top of the mounting base 1, a movable plate 4 is provided on the other side of the top of the mounting base 1, and a mounting positioning component 3 for installing the tool is provided on the top of the fixed plate 2 and the movable plate 4;

[0027] The mounting and positioning assembly 3 includes a lower mounting plate 31 disposed on the top of the movable plate 4 or the fixed plate 2, an upper mounting plate 32 is disposed on the top of the lower mounting plate 31, and a through mounting hole 33 that matches the tool is opened transversely at the connection between the upper mounting plate 32 and the lower mounting plate 31. This design facilitates the placement of the tool by using the mounting hole 33, and the tool inside the mounting hole 33 is installed through the upper mounting plate 32 and the lower mounting plate 31;

[0028] A pair of convex grooves 6 are symmetrically provided on the top of the mounting base 1, and a pair of convex blocks 5 matching the convex grooves 6 are provided at positions corresponding to the convex grooves 6 at the bottom of the movable plate 4. A plurality of first threaded holes 101 connected to the adjacent convex grooves 6 are provided on the opposite side walls of the mounting base 1. A retaining bolt 8 for tightening the side wall of the convex block 5 is provided inside the plurality of first threaded holes 101. This design applies force to the movable plate 4 to move the movable plate 4 toward the side close to the fixed plate 2. The movement of the movable plate 4 causes the convex block 5 to move along the convex groove 6, thereby improving the stability of the lateral movement of the movable plate 4. , so that the installation and positioning assembly 3 on the movable plate 4 is close to the installation and positioning assembly 3 on the fixed plate 2, thereby adjusting the distance between the installation holes 33 in a pair of installation and positioning assemblies 3 to adapt to the installation of tools of different sizes. Finally, the convex block 5 is pressed and stopped by using the stop bolt 8, thereby preventing the movable plate 4 on the convex block 5 from moving horizontally, and further preventing the installation and positioning assembly 3 on the movable plate 4 from moving horizontally, thereby preventing the tool connection at the fixed position from loosening, completing the installation and fixation of tools of different sizes, facilitating the installation and fixation of tools of different sizes, and having high versatility.

[0029] Reference Figure 1 、 Figure 2 and Figure 3 The stop bolt 8 includes a screw head 82 and a stud 81. The stud 81 is arranged at the end of the screw head 82. The stud 81 is connected to the first threaded hole 101 by a thread. A guide groove 51 is horizontally opened on the side of the convex block 5 close to the first threaded hole 101, and a guide column 811 matching the guide groove 51 is provided on the end of the stud 81 away from the screw head 82. This design guides the convex block 5 when it moves along the convex groove 6 by inserting the guide column 811 into the guide groove 51, thereby further improving the stability of the lateral movement of the convex block 5. At the same time, the stud 81 is connected to the first threaded hole 101 to press the side wall of the convex block 5, thereby stopping the convex block 5, and then stopping the installation and positioning assembly 3 on the movable plate 4, thereby improving the stability of the tool fixing and preventing the connection from loosening.

[0030] Reference Figure 2 and Figure 3The diameter of the screw head 82 is larger than the diameter of the stud 81, the diameter of the stud 81 is larger than the diameter of the guide column 811, and the diameter of the guide column 811 is equal to the height of the guide groove 51, which improves the rationality of the design.

[0031] Reference Figure 1 , a plurality of marking lines 7 are provided on the top of the mounting base 1, which are located directly above the stop bolts 8. The marking lines 7 correspond to the stop bolts 8 one by one. This design facilitates observation of the position of the movable plate 4 by using the marking lines 7, so that it can be determined which stop bolt 8 is used to tighten the convex block 5. When tightening, at least two stop bolts 8 are used to tighten the convex block 5 according to needs to ensure the stability of the connection and avoid loosening of the connection.

[0032] Reference Figure 4 and Figure 5 The top of the upper mounting plate 32 is provided with a plurality of mounting bolts 34 that pass through the upper mounting plate 32 and are connected to the second threaded holes 36. The bottom of the lower mounting plate 31 is symmetrically provided with a stop pin 37, and the bottom of the upper mounting plate 32 is provided with a stop hole 38 that matches the stop pin 37 at a position corresponding to the stop pin 37. This design improves the accuracy of the tool installation of the mounting hole 33 by using the stop pin 37 to connect with the stop hole 38, while ensuring that the mounting bolt 34 corresponds to the second threaded hole 36, speeding up the speed of the upper mounting plate 32 and the lower mounting plate 31 to install and fix the tool inside the mounting hole 33, and under the action of the mounting bolt 34 and the second threaded hole 36, the tool connection is prevented from loosening, and at the same time, the tool connection is further prevented from loosening under the action of the stop bolt 8 pressing the convex block 5, thereby improving the stability of the tool fixing.

[0033] Reference Figure 1 and Figure 2 Force-applying grooves 35 are provided on the two opposite side walls of the upper mounting plate 32 . This design facilitates applying force to the upper mounting plate 32 so that the upper mounting plate 32 is separated from the lower mounting plate 31 by using the force-applying grooves 35 .

[0034] Reference Figure 1 Extension plates 9 are provided on the two opposite side walls of the mounting base 1, and fixing holes 10 are symmetrically opened on the top of the extension plates 9. This design facilitates the fixation of the extension plates 9 by connecting with external bolts through the fixing holes 10, thereby facilitating the fixation of the mounting base 1 and improving the rationality of the design.

[0035] Reference Figure 1-Figure 5As an embodiment of the present invention: when the tool needs to be installed, the staff applies force to the mounting bolts 34 to loosen the upper mounting plate 32 and the lower mounting plate 31, and then inserts the tool into the mounting hole 33. Finally, the mounting bolts 34 are tightened to make the upper mounting plate 32 and the lower mounting plate 31 fit tightly, thereby pressing and fixing the tool inside the mounting hole 33.

[0036] When it is necessary to install tools of different sizes, force is applied to the movable plate 4 to move the movable plate 4 toward the side close to the fixed plate 2. The movement of the movable plate 4 causes the convex block 5 to move along the convex groove 6, thereby improving the stability of the lateral movement of the movable plate 4, so that the installation positioning component 3 on the movable plate 4 is close to the installation positioning component 3 on the fixed plate 2, thereby adjusting the distance between the mounting holes 33 in the pair of installation positioning components 3 to adjust the distance to the tool of the appropriate size, and then, force is applied to the mounting bolts 34 to loosen the space between the upper mounting plate 32 and the lower mounting plate 31, and then the tool is inserted into the adjusted pair of installation positioning components. The inside of the mounting hole 33 in the positioning component 3 is then tightened with the mounting bolts 34 to make the upper mounting plate 32 and the lower mounting plate 31 fit tightly together, which can complete the installation and fixation of tools of different sizes, and plays a role in facilitating the installation and fixation of tools of different sizes, with high versatility. Finally, the convex block 5 is pressed and stopped by using the stop bolt 8, thereby preventing the movable plate 4 on the convex block 5 from moving horizontally, and further preventing the installation and positioning component 3 on the movable plate 4 from moving horizontally, thereby preventing the tool connection at the fixed position from loosening, further preventing the tool connection from loosening, improving the stability of the tool fixing position, and improving the practicality of the present utility model.
