DETAILED DESCRIPTION
[0030] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Example 1
[0031] The utility model provides an adjustable high-speed steel drill bit fixing bracket, please refer to Figure 1-3 , including a support plate 1, on which a plurality of drill sleeves 2 are fixedly mounted, lubricating oil being provided in the drill sleeves 2, the drill sleeves 2 being a hollow structure with an opening at the top, and the top of the drill sleeves 2 being blocked by a blocking member.
[0032] The blocking member is configured as a cover plate 3 , the top end of the cover plate 3 is integrally provided with a knob 31 , and the cover plate 3 covers the top end of the drill sleeve 2 .
[0033] The bottom of the cover plate 3 is provided with a threaded pin 32. The inner wall of the top end of the drill sleeve 2 is provided with an internal thread matching the threaded pin 32. The threaded pin 32 and the drill sleeve 2 are threadedly connected. A rubber sleeve 4 is bonded to the bottom of the threaded pin 32. The rubber sleeve 4 is a hollow structure, and the diameter of the inner cavity is smaller than the diameter of the drill shank. Therefore, after the drill shank is inserted into the rubber sleeve 4, the rubber sleeve 4 can clamp the drill shank, thereby ensuring the stability of the drill bit in the drill sleeve 2.
[0034] Of course, by controlling the length of the rubber sleeve 4 , the gravity of the drill bit will not cause the drill bit to separate from the rubber sleeve 4 in a natural state.
[0035] During actual use, lubricating oil is injected into each drill casing 2, a drill bit is placed in each drill casing 2, and the cover plate 3 is put on, so that the drill bit is fixedly stored in the drill casing 2, thereby achieving lubrication and preservation of the drill bit. Example 2
[0036] Refer to the attached Figure 4-7 , which is different from Example 1: the top of each drill bit casing 2 is commonly covered with a sealing plate 5, the bottom of the sealing plate 5 is bonded with a sealing gasket 6, an elastic stretching component is installed on the support plate 1, and both ends of the sealing plate 5 are connected to the elastic stretching component;
[0037] Under the elastic force of the elastic stretching assembly, the blocking plate 5 and the sealing gasket 6 are tightly covered on each drill bit sleeve 2.
[0038] The elastic stretching component includes a hanging ring 12 welded to the outer wall of the support plate 1, a hook 8 is hung on the hanging ring 12, an elastic rope 7 is fixedly connected to the hook 8, the other end of the elastic rope 7 is fixedly connected to the support blocks 51 at both ends of the sealing plate 5, a notch 13 is opened on the support plate 1, and the inner wall of the notch 13 is slidably connected to the support block 51; at this time, one sealing plate 5 covers all the drill bit sleeves 2 together, so that each drill bit sleeve 2 can be opened or closed synchronously, making it more convenient to take and put multiple drill bits.
[0039] During actual use, lubricating oil is injected into each drill casing 2, the drill bit is placed in each drill casing 2, the sealing plate 5 is covered on the top of each drill casing 2, and the hook 8 is hung on the hanging ring 12. The elastic force of the elastic rope 7 drives the sealing plate 5 to close tightly, so that the drill bit is fixed and stored in the drill casing 2, thereby achieving lubrication and preservation of the drill bit. Example 3
[0040] Refer to the attached Figure 8-9 , which is different from Example 1: a spring 10 is provided in the drill sleeve 2, and a fixing plate is welded at both ends of the spring 10. The two fixing plates are fixedly connected to the sealing plate 9 and the bottom wall of the drill sleeve 2 by bolts respectively. A support ring 21 is welded in the drill sleeve 2, and a rubber plate 91 is adhered to the top of the sealing plate 9; the liquid level of the lubricating oil is lower than the height of the support ring 21 and is ensured to be able to immerse the screw-in part of the drill bit; when the drill bit is stored, the drill bit presses down the sealing plate 9, so that the drill bit is stored in the drill sleeve 2; at this time, if the drill bit is not stored in the drill sleeve 2, the elastic force of the spring 10 drives the sealing plate 9 to block the support ring 21, thereby preventing the leakage of the lubricating oil and preventing external dust from entering the drill sleeve 2 and contaminating the lubricating oil.
[0041] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
