[0002] The grinding rod allows the grinding wheel to enter the part and contact the surface to be ground. It is a highly customized and extremely close-tolerance tool, and can be considered an extension of the spindle itself. For spindle manufacturers, it is obviously uneconomical to design and produce thousands of different spindles to meet every possible part geometry. Instead, they produce a unified standard interface, allowing customers to design grinding rods according to their needs. Excellent grinding rod design has a long life, allowing users to install grinding wheels again and again.

[0003] Furthermore, the load-bearing capacity of the threaded grinding heads of most current grinding rods is not high enough, resulting in a low load-bearing capacity of the existing grinding rods, which are easily damaged during processing. Utility Model Content

The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included. Example

[0028] Reference Figure 1-5The utility model discloses a large-lead threaded grinding head and angle grinding rod structure, including a grinding rod body 101. The grinding rod body 101 serves as the main structure of the entire structure and is mainly used for installation on modern machine tools. A grinding rod head 102 is provided at the front end of the grinding rod body 101. The grinding rod head 120 is integrally formed with the grinding rod body 101, and the overall structure of the grinding rod body 101 and the grinding rod head 102 are both cylindrical, and the size of the grinding rod head 102 is smaller than that of the grinding rod body.

[0029] Furthermore, a connecting thread 103 is provided on the end of the grinding rod head, and a grinding head 104 is threadedly connected to the grinding rod head 102. The grinding head 104 is connected to the grinding rod body 101 by plugging. In this embodiment, the connecting thread 103 is a large lead thread, which has the following characteristics:

[0030] 1. High efficiency: Due to the large lead value, the large lead thread moves a greater distance per rotation, so it has faster loading and unloading speed and efficient transmission force in threaded connections;

[0031] 2. Strong load-bearing capacity: Due to the large moving distance of the large lead thread, there are more thread lines within a given length, thereby increasing the force transmission area and improving the load-bearing capacity of the threaded connection.

[0032] Furthermore, a connecting block 105 is provided at the rear end of the grinding rod body 101 , and a connecting component 200 is provided between the grinding rod body 101 and the connecting block 105 .

[0033] In this embodiment, the connecting component 200 includes a first pressing edge 201 provided at the rear end of the grinding rod body 101 and a second pressing edge 202 cooperating with the first pressing edge 201 . A connecting unit 203 is provided on the first pressing edge 201 .

[0034] Preferably, in this embodiment, the connecting monomer 203 includes a groove 203 ring provided on the first pressing edge 201 and a card edge 203b provided on the groove 203 ring. The groove 203 rings are arranged close to each other, and the card edges 203b between the groove 203 rings are close to each other but not in contact. The two card edges 203b correspond to a concave groove 205, and the lateral width of the concave groove 205 is greater than the width between the two card edges 203b. The card edge 203b cooperates with the mating bayonet 203c, and the mating bayonet 203c is opened on the four sides of the mating pattern 204, and the position of the mating bayonet 203c is higher. The position height of the mating bayonet 203c is set at a position away from the recessed groove 205. When the card edge 203b is pressed down, the card edge 203b is obstructed and guided by the curvature of the recessed groove 205 and the edge position of the mating pattern 204, and the card edge 203b flips up, thereby being stuck in the mating bayonet 203c.

[0035] In this embodiment, the clamping edge 203b includes a connecting piece 203d connected to the groove 203 ring and a bending portion 203e arranged on the connecting piece 203d. The several clamping edges 203b on each groove 203 ring are not connected to each other, that is, the connecting pieces 203d on each groove 203 ring are not interconnected, and thus each connecting piece 203d can be bent individually. This setting ensures that when each groove 203 ring is clamped, if one connecting piece 203d occasionally fails to clamp or is misaligned, the remaining connecting pieces 203d can still be clamped individually.

[0036] Moreover, each connecting piece 203d is not connected to each other, thereby forming a certain gap. This gap allows the connecting pieces 203d to deform and expand after being pressed together, thereby filling the gap and enhancing the connection stability.

[0037] Furthermore, in this embodiment, the bending portion 203e includes a first arc surface 204 and a second arc surface 205. The curvature of the first arc surface 204 is smaller than that of the second arc surface 205. The first arc surface 204 is arranged at an end position closer to the clamping edge 203b, and the second arc surface 205 is arranged at a rear position. A mating arc groove 206 that cooperates with the bending portion 203e is provided on the recessed groove 205. The clamping edge 203b also includes a bending hook 203f arranged at the front end of the bending portion 203e and mating with the mating bayonet 203c.

[0038] Operation process: During pressing, the bending hook 203f first contacts the mating arc groove 206, and then under the arc action of the mating arc groove 206, the bending hook 203f bends, and extends upward after bending. As the pattern 203 ring continues to press down, the bending portion 203e enters the mating arc groove 206. Because the bending portion 203e is also in contact with the mating arc groove 206, and because of the cooperation between the arc surfaces, the first arc surface 204 of the bending portion 203e is bent.

[0039] A fold 300 is provided at the junction of the first arc surface 204 and the second arc surface 205, and an extension 302 extends on the side wall of the matching pattern 204. At this time, as the pattern 203 ring is pressed downward, the pattern 203 ring will also press the matching pattern 204 downward. The downward pressure of the matching pattern 204 will drive the extension 302 on the matching pattern 204 to be pressed downward, thereby pressing the position of the fold 300, thereby pressing the card edge 203b into a "folded" state. At this time, the bent hook 203f can cooperate with the matching bayonet 203c, thereby achieving locking and sealing.
