[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The drilling device for this precision metal parts has a protective component on the base on which the metal parts are fixed. The cover in the protective component covers the base, which limits the range of debris splashing during drilling and eliminates safety hazards. At the same time, the entire protective component has a simple structure, is easy to operate, and is more in line with actual application scenarios.

[0014] 2. The drilling device for this precision metal parts also includes an auxiliary component on the base. The state of the stop block in the auxiliary component is linked to the position of the cover through other components contained in the auxiliary component. Therefore, the stop block can only retract into the fixed column when the cover is in the protective state, thus releasing the restriction of the electric slide. Only then can the height of the drill be adjusted for drilling. This avoids drilling operations before the base is fully covered by the cover, thereby preventing user error and further improving the overall performance of the device. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 A drilling device for precision hardware parts includes: a base 1, a positioning block 2 on the upper surface of the base 1, and a column 5 fixedly installed on the upper surface of the base 1. An electric slide block 4 is slidably connected to the column 5, and a drill rig 3 is fixedly installed on the bottom surface of the electric slide block 4 adjacent to the base 1.

[0024] A protective component 6 is provided on the base 1. The protective component 6 includes a cover 61 slidably connected to the base 1. A handle 62 is fixedly installed on the front of the cover 61. An insert rod 67 is slidably arranged inside the cover 61. A connecting plate 63 is fixedly installed at the end of the insert rod 67 that passes through the cover 61. A return spring 68 is provided between the connecting plate 63 and the cover 61. A pull ring 64 is also fixedly installed on the side of the connecting plate 63. A limit ring 66 is fixedly installed on the inner surface of the cover 61. An insertion hole 65 is provided on the base 1 for inserting the insert rod 67. The length of the insert rod 67 is greater than the thickness of the cover 61. The end of the insertion rod 67 away from the connecting plate 63 can be inserted into the insertion hole 65. The two ends of the return spring 68 are fixedly connected to the connecting plate 63 and the cover 61 respectively. There are two return springs 68. The insertion rod 67 is located in the cavity inside the return spring 68. The number of insertion rods 67 is the same as the number of return springs 68. There are also two limiting rings 66. The side of the limiting ring 66 can contact the side of the base 1. The limiting ring 66 can be used to maintain a stable sliding connection between the cover 61 and the base 1 to avoid excessive sliding and detachment of the cover 61.

[0025] An auxiliary component 7 is also provided on the base 1. The auxiliary component 7 includes a fixed column 71 fixedly connected to the base 1 and a transmission rack 74 fixedly installed on the back of the cover 61. A stop 72 is slidably provided on the fixed column 71, and a gear shaft 75 and a screw 77 are rotatably provided inside the fixed column 71. A transmission gear 73 is fixedly installed at the end of the gear shaft 75 that passes through the fixed column 71. The transmission gear 73 meshes with the transmission rack 74. A pulley set 76 is provided on the shaft of the gear shaft 75, and the gear shaft 75 is connected to the screw 77 through the pulley set 76. The inner cavity of the stop 72... A fixing nut 78, threadedly connected to the screw 77, is fixedly installed on the side wall of the stop 72. A limiting block 79 is fixedly installed at the end of the screw 77. The limiting block 79 is also located in the cavity inside the stop 72. The size of the limiting block 79 is larger than the size of the threaded through hole on the fixing nut 78. The stop 72 is located below the electric slide 4. In the initial state, the stop 72 is within the stroke range of the electric slide 4. The stop 72 can be used to restrict the sliding of the electric slide 4 when the cover 61 is not yet protected, to prevent the user from forgetting to pull up the cover 61 for protection, so that the overall structure has a foolproof function and improves practicality.

[0026] Working principle: The positioning block 2 is engaged with the threaded hole on the base 1 by bolts to form a hole system combination fixture of existing technology, which fixes the hardware to be processed on the base 1. Then, the electric slide 4 and the drill 3 are started respectively. While the column 5 slides, the electric slide 4 can also drive the drill 3 to slide towards the hardware to perform drilling. The electric slide 4 and the drill 3 are both existing technologies, so their specific operation steps and principles will not be elaborated in this article.

[0027] Before drilling, pull the connecting plate 63 with the pull ring 64 to retract the insertion rod 67 fixed on the connecting plate 63 into the cover 61. Then, push the cover 61 upward with the handle 62. After the cover 61 covers the base 1, release the pull ring 64. Under the elastic force of the return springs 68, which are fixedly connected to the connecting plate 63 and the cover 61 at both ends, the insertion rod 67 can pass through the cover 61 and be inserted into the insertion hole 65 on the base 1, thus restricting the position of the cover 61. At this time, the cover 61 closes the perimeter of the hardware on the upper surface of the base 1, thereby reducing the range of debris splashing. While the cover 61 slides upward on the base 1, the transmission rack 74 fixed on the side of the cover 61 meshes with the transmission gear 73, driving the transmission through the gear shaft 75 and the fixed... The transmission gear 73, which is rotatably connected to the fixed column 71, rotates together. At the same time, the gear shaft 75 and the screw 77 are also connected by a pulley set 76. The stop block 72, which is slidably set on the fixed column 71, has a fixed nut 78 that is threadedly connected to the screw 77 inside. Therefore, when the cover 61 slides upward, the stop block 72 slides into the fixed column 71 under the transmission of the transmission rack 74, transmission gear 73, gear shaft 75, pulley set 76, screw 77 and fixed nut 78 in sequence. When the cover 61 reaches the designated protection position, the stop block 72 also disengages from the travel range of the electric slide block 4. Only when the cover 61 is slid up to the protection position can the electric slide block 4 drive the drill rig 3 to slide downward for drilling.
