[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the tap deburring device provided by this utility model. Figure 1 ;

[0022] Figure 2 A schematic diagram of a preferred embodiment of the tap deburring device provided by this utility model. Figure 2 ;

[0023] Figure 3 This is a schematic diagram of the internal structure of the processing box in this utility model;

[0024] Figure 4 This is a schematic diagram of the structure of the second adjustment component and the processing component in this utility model.

[0025] A tap deburring device includes: a base plate 1, a processing box 2 mounted on the base plate 1, an outer protective cover 3 rotatably connected to the processing box 2, an installation plate 4 inside the processing box 2, a partition plate 5 fixedly connected to the installation plate 4, a first grinding chamber 6 and a second grinding chamber 10 on the left and right sides of the partition plate 5 respectively, a first three-jaw chuck 7 and a first adjusting component 8 in the first grinding chamber 6, a grinding wheel 9 mounted on the first adjusting component 8, a second three-jaw chuck 11 and a second adjusting component 13 in the second grinding chamber 10, a first drive motor 12 mounted on the processing box 2, the output end of the first drive motor 12 passing through the processing box 2 and connected to the second three-jaw chuck 11, a processing component 14 mounted on the second adjusting component 13, and a control area 15 on the side of the processing box 2.

[0026] The first grinding chamber 6 and the second grinding chamber 10 can process two taps simultaneously. During processing, the shank of the tap is clamped by the first three-jaw chuck 7 and the second three-jaw chuck 11. When the tap in the first grinding chamber 6 is being processed, the grinding wheel 9 processes the end face of the tap near the tooth body. When the tap in the second grinding chamber 10 is being processed, the processing component 14 performs a more refined grinding process on the tooth body.

[0027] The first adjustment assembly 8 includes a first lead screw 81, a first guide slide 83, and a first movable seat 84. The first lead screw 81 is rotatably connected to the processing box 2. A handle 82 is fixedly connected to one end of the first lead screw 81 extending outside the processing box 2. The first movable seat 84 is sleeved on the first lead screw 81 and the first guide slide 83. A first fixed plate 85 is provided on the first movable seat 84. The grinding wheel 9 is provided on the first fixed plate 85.

[0028] The grinding wheel 9 is used to grind the end face of the tap near the tooth body. When in use, the handle 82 is turned to control the first moving seat 84 to move closer to or away from the tap along the direction of the first guide slide 83.

[0029] The second adjustment assembly 13 includes a second lead screw 131, a second guide slide 133, and a second movable seat 134. The second lead screw 131 is rotatably connected to the processing box 2. One end of the second lead screw 131 extending outside the processing box 2 is connected to a second drive motor 132. The second movable seat 134 is sleeved on the second lead screw 131 and the second guide slide 133. The second movable seat 134 is provided with a second fixed plate 135 and a lifting push rod 136. The second fixed plate 135 is provided with a sliding groove 137.

[0030] The second lead screw 131, the second drive motor 132, and the second guide slide 133 control the second moving seat 134 to slide along the direction of the second guide slide 133 so as to grind different parts of the tap. Unlike the first adjustment component 8, since the second adjustment component 13 needs to frequently adjust the position of the second moving seat 134 during use, a drive motor is used as the power source to reduce labor intensity.

[0031] The processing component 14 includes a fixed base 141, which is slidably connected to a slide groove 137. A grinding brush 142 is provided on the upper part of the fixed base 141, and a chamfering block 143 is provided on the lower part of the fixed base 141. A fastening screw 144 is provided on the chamfering block 143, and the chamfering block 143 is fixedly connected to the fixed base 141 by the fastening screw 144.

[0032] When further refining the tap tooth body in the second grinding chamber 10, the lifting push rod 136 is first controlled to raise the chamfering block 143 above the end face of the tap near the tooth body, and then slowly lowers it until it contacts the tap for chamfering. After grinding, the second moving seat 134 retracts while the fixed seat 141 descends along the slide 137 under the control of the lifting push rod 136 until the grinding brush 142 is below the tap. The grinding brush 142 is then activated to perform a fine burr removal process on the tooth body. When the tap is processed in the second grinding chamber 10, the output end of the first drive motor 12 is connected to the chassis of the second three-jaw chuck 11 through the processing box 2, so the tap rotates and is chamfered by the chamfering block 143. When the grinding brush 142 is working, the first drive motor 12 stops running and the tap is stationary. The chamfering block 143 is fixedly connected to the fixed seat 141 by the fastening screw 144 for easy replacement after wear.

[0033] The outer protective cover 3 is provided with an observation window 16.

[0034] The observation window 16 facilitates observation of the polishing process and allows for easy stopping at any time.

[0035] Waste boxes 17 are slidably connected to both sides of the lower part of the processing box 2.

[0036] Waste box 17 is used to collect waste generated during the grinding of taps in the first grinding chamber 6 and the second grinding chamber 10.

[0037] The working principle of the tap deburring device provided by this utility model is as follows:

[0038] The first grinding chamber 6 and the second grinding chamber 10 can process two taps simultaneously. During processing, the shank of the tap is clamped by the first three-jaw chuck 7 and the second three-jaw chuck 11. When the tap in the first grinding chamber 6 is being processed, the grinding wheel 9 processes the end face of the tap near the tooth body. When the tap in the second grinding chamber 10 is being processed, the processing component 14 performs a more refined grinding process on the tooth body.

[0039] Compared with related technologies, the tap deburring device provided by this utility model has the following advantages:

[0040] Beneficial effects:

[0041] The first grinding chamber 6 and the second grinding chamber 10 can process two taps simultaneously. The end face of the tap near the tooth body is processed first in the first grinding chamber 6, and then it is transferred to the second grinding chamber 10 for more refined grinding of the tooth body, which improves the efficiency of deburring. The outer protective cover 3 and the waste box 17 prevent small grinding debris from flying and reduce the difficulty of cleaning.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
