Detailed Implementation
[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0025] Example 1:
[0026] like Figure 1-3 As shown, a drilling fixture with a toothed hob for effective cooling includes an adjusting mechanism 100 and a main body mechanism 200 located on top of the adjusting mechanism 100. Before use, check the integrity of each component of the fixture. Check whether the support rod 108 is securely connected to the four corners of the bottom of the base plate 101, and whether the fixing plate 109 can be placed stably on the ground to ensure the fixture is stable. Check whether the pump body 112 is working properly, whether the water pipe 113 is damaged or bent, and whether the spray holes of the spray plate 114 are unobstructed to ensure the normal operation of the cooling system. At the same time, confirm that the filter plate 204 is firmly installed and that the filter tank 205 and the pipe 206 are not blocked so that wastewater can be discharged in time.
[0027] In this embodiment, the blank 208 to be processed is placed on the rotating seat 207. The position of the blank 208 is adjusted by the rotation function of the rotating seat 207 so that the part to be drilled is aligned with the chuck 209. The toothed hob is installed on the chuck 209 of the work box 210, and it is ensured that the installation is firm to avoid the drill bit from becoming loose during the drilling process.
[0028] In this embodiment, the pump body 112 is started, and the pump body 112 delivers water to the spray plate 114 through the water pipe 113. The spray plate 114 sprays water onto the toothed hob drill bit and the drilling area to cool the drill bit. When the water flows through the filter plate 204, the filter plate 204 filters out debris and other impurities in the water. The filtered water flows into the collection tank 111 of the collection box 110 through the filter tank 205 and the pipe 206, thereby collecting the wastewater.
[0029] In this embodiment, when the drilling angle needs to be adjusted, the operator holds the handle 104 and rotates it to rotate the rotating rod 103. The rotating rod 103 drives the lead screw 102 to rotate, and the moving block 105 at the top of the lead screw 102 moves on the lead screw 102. Because the limiting piece 106 at the bottom of the moving block 105 slides within the groove 107, the moving block 105 can only move smoothly along the direction of the groove 107. During the movement of the moving block 105, one end of the working plate 201 is lifted, thereby realizing the adjustment of the drilling angle of the rough blank 208 to meet different drilling requirements.
[0030] In this embodiment, after drilling is completed, pump 112 is turned off to stop water spraying for cooling. Collection box 110 is removed from the bottom of base plate 101, and wastewater and debris in collection tank 111 are cleaned. The toothed hobbing drill bit is inspected for wear; if wear is found, it is replaced or repaired promptly. Residual debris on components such as work plate 201 and filter plate 204 is cleaned to prepare for the next drilling operation.
[0031] In this embodiment: When in use, the screw 102 at one end of the rotating rod 103 is rotated by the hand ring 104, so that the moving block 105 at the top of the screw 102 moves and lifts one end of the working plate 201, which can adjust the drilling angle of the blank 208 to meet the actual use requirements. At the same time, when the moving block 105 moves, the limiting piece 106 at the bottom of the moving block 105 slides within the slide groove 107.
[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
