Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-frequency welding devices, in particular to a high-frequency welding device for a drill bit. Background Art
[0002] High-frequency welding can be divided into contact high-frequency welding and induction high-frequency welding according to the way high-frequency current generates heat in the workpiece. In contact high-frequency welding, the high-frequency current is transmitted to the workpiece through mechanical contact with the workpiece. In induction high-frequency welding, the high-frequency current generates an induced current in the workpiece through the coupling effect of the induction coil outside the workpiece.
[0003] During the use of drill bits, the drill bits are prone to problems such as breakage. At this time, it is necessary to use welding to weld the two broken parts together. This step is generally performed by induction high-frequency welding. The position of the induction coil in the existing device is generally fixed. When not in use, it is exposed to the external environment and is not fully protected. In view of this, in-depth research was conducted on the above-mentioned problems, which led to the present case. Utility Model Content
[0004] The utility model aims to provide a high-frequency welding device for a drill bit, so as to solve the problem that the induction coil is not well protected in the above-mentioned background technology.

[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] By providing an installation box, when the high-frequency welding induction coil is not in use, the electric telescopic rod is used to pull the moving plate to move, so that the high-frequency welding induction coil is retracted into the installation box. At the same time, the movement of the moving plate can also pull the pull rope through the sliding block, so that the flip plate is pulled and rotated, and the two flip plates block the bottom opening of the installation box, thereby providing all-round protection for the high-frequency welding induction coil.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Example: See Figure 1-4 , a high-frequency welding device for a drill bit grinding comprises a workbench 2, vertical plates 5 are fixed on both sides of the workbench 2, an installation box 8 is arranged above the workbench 2, and fixed rods 9 are fixed on both sides of the installation box 8, one end of the fixed rods 9 is fixed to one side of the vertical plate 5, a movable plate 12 is arranged inside the installation box 8, and a high-frequency welding induction coil 13 is installed at one end of the movable plate 12, fixed plates 14 are fixed at the front and rear ends of the bottom end of the installation box 8, and two flip plates 15 are installed between one ends of the two fixed plates 14 through a rotating shaft, fixed boxes 10 are installed on both sides of the interior of the installation box 8, and sliding blocks 11 are arranged inside the fixed boxes 10, one side of the sliding blocks 11 is connected to one side of the movable plate 12 through a fixing member, a fixed sleeve 17 is fixed to the bottom end of the interior of the fixed box 10, a pull rope 16 is fixed to the bottom end of the slide block 11, and the bottom end of the pull rope 16 runs through the interior of the fixed sleeve 17, and the bottom end of the pull rope 16 is connected to the top of the flip plate 15;
[0021] The interior of the fixed box 10 has the same cross-sectional shape as the sliding block 11, and the connection between the sliding block 11 and the fixed box 10 is a sliding connection;
[0022] Two electric telescopic rods 7 are installed on the top of the installation box 8, and the output ends of the electric telescopic rods 7 are connected to one end of the moving plate 12 through bolts;
[0023] Specifically, Figure 1 and Figure 2 As shown, when the high-frequency welding induction coil 13 is not in use, the electric telescopic rod 7 can be started, causing the electric telescopic rod 7 to pull the movable plate 12 to move, thereby storing the high-frequency welding induction coil 13 into the installation box 8, and then continue to pull the movable plate 12. At the same time, the sliding block 11 follows the movable plate 12 to slide upward inside the fixed box 10, and the flip plate 15 is rotated by pulling the pull rope 16, so that the two flip plates 15 cooperate to block the bottom gap of the installation box 8. On the contrary, when the high-frequency welding induction coil 13 is used, the electric telescopic rod 7 is started to push the high-frequency welding induction coil 13. Since the pull rope 16 is loose, the flip plate 15 naturally rotates open due to gravity, and will not block the moving path of the high-frequency welding induction coil 13.
[0024] The shape of the fixing sleeve 17 is S-shaped;
[0025] A plurality of balls 18 are embedded in the inner wall of the fixing sleeve 17, and the balls 18 are in contact with the outer wall of the pull rope 16;
[0026] Specifically, Figure 2 , Figure 3 and Figure 4 As shown, the ball 18 contacts the pull rope 16 to reduce friction and facilitate the movement of the pull rope 16. The fixing sleeve 17 is designed to be S-shaped, which can make the rope also form an S-shape in this area, thereby preventing the loose rope inside the fixing box 10 from naturally sliding out of the fixing sleeve 17, causing the rope outside the fixing box 10 to be too long and loose.
[0027] Pneumatic push rods 1 are installed on both sides of the vertical plate 5, and the output ends of the pneumatic push rods 1 extend to one side of the vertical plate 5 and are installed with three-claw grippers 3;
[0028] A water baffle 6 is fixed between one side of the two vertical plates 5, and the bottom end of the water baffle 6 is welded to one end of the top of the workbench 2. A plurality of water leakage holes 4 are vertically penetrated inside the workbench 2.
[0029] Specifically, Figure 1 As shown, the three-jaw clamp 3 can be used to clamp the broken drill bit, and the two broken parts are aligned and contacted by pushing and shifting the pneumatic push rod 1. When water cooling is used after welding, the water baffle 6 can be used to prevent a large amount of water from splashing out, and the leakage hole 4 can prevent water from being retained above the workbench 2.
[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
