Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances. Example

[0035] This utility model discloses a clamping mechanism for a box-type casting. The box-type casting has a machining hole 51 to be re-threaded. The clamping mechanism includes: a mounting plate 1, a positioning device 2, and a machining device 3. The positioning device 2 is slidably mounted on the mounting plate 1 and is used to position the product 5. The machining device 3 is fixedly mounted on the mounting plate 1 and is arranged opposite to the positioning device 2. The machining device 3 includes a drive assembly 4 and a tapping tool 32 detachably mounted on the drive assembly 4. The tapping tool 32 is coaxial with the machining hole of the box-type casting. The drive assembly 4 drives the tapping tool 32 to tap the machining hole 51, and the positioning device 2 slides along the mounting plate 1 under the drive of the tapping tool 32.

[0036] Specifically, in this embodiment, the product being processed is a box-type casting. The box-type casting has machining holes 51 for re-threading. The clamping mechanism clamps and positions the box-type casting before performing re-threading on its machining holes. A positioning device 2 is provided on one side of the mounting plate 1. The positioning device 2 is slidably mounted on the mounting plate 1 to facilitate the processing of the product 5. The positioning device 2 is used to position and fix the product 5. A processing device 3 is provided on the other side of the mounting plate 1. The processing device 3 is fixedly connected to the mounting plate 1, and the processing device 3 is positioned opposite to the positioning device 2.

[0037] The machining device 3 includes a drive assembly 4 and a tapping tool 32. The tapping tool 32 is detachably connected to the drive assembly 4 (similar to how machining tools on a lathe can be bolted together). The drive assembly 4 drives the tapping tool 32 to rotate. The tapping tool 32 is used for back-thread machining of the machined hole 51. The tapping tool 32 is coaxially positioned with the machined hole of the box casting. When the machined hole 51 of the product 5 is not engaged with the tapping tool 32, the operator slides the positioning device 2 along the mounting plate 1 until the tapping tool 32 enters the machined hole 51. The tapping tool 32 taps and connects to the machined hole 51. The drive assembly 4 is then activated to drive the tapping tool 32 to rotate, thereby performing back-thread machining on the machined hole 51. During this process, because the tapping tool 32 is engaged with the machined hole 51, the positioning device 2 continues to slide along the mounting plate 1 while the tapping tool 32 is rotating. After the re-threading is completed, start the drive assembly 4 to rotate the tapping tool 32 in the opposite direction to separate the two. After separation, remove the box casting from the positioning device 2 to complete the re-threading.

[0038] Specifically, in this embodiment, after positioning the product 5 by setting the positioning device 2, the machining hole 51 of the product 5 is connected to the tapping tool 32, and the driving component 4 is used to drive the tapping tool 32 to rotate, thereby performing thread rewinding on the product 5, which speeds up the processing efficiency. Moreover, the tapping tool 32 and the product 5 work together to drive the product 5 to move in the direction of the tapping tool 32, which better performs thread rewinding on the product 5 without damaging the threads, thus making the pass rate higher.

[0039] Furthermore, as a preferred embodiment, the positioning device 2 includes a vertically intersecting positioning plate 21 and a vertical plate 22, and a positioning block 23 is provided on the vertical plate 22. The outer contour of the positioning block 23 is matched with the inner wall of the box-type casting for positioning.

[0040] Furthermore, as a preferred embodiment, the positioning block 23 includes a stepped block body 231 and at least one positioning protrusion 232 that partially protrudes from the block body 231. The positioning protrusion 232 and the block body 231 are used to insert into the limiting box casting.

[0041] Specifically, in this embodiment, the upper end of the mounting plate 1 is provided with a vertically intersecting positioning plate 21 and a vertical plate 22. The positioning plate 21 is slidably mounted on the mounting plate 1, and the upper end of the positioning plate 21 is provided with the vertical plate 22. The positioning plate 21 and the vertical plate 22 are integrally formed. A positioning block 23 (bolted connection and fixation) is detachably provided on the side of the vertical plate 22 near the processing device 3. The positioning block 23 includes a stepped block body 231 and a positioning protrusion 232 protruding from the block body 231. The outer contour of the block body 231 is matched with the inner wall of the box casting for positioning. The positioning protrusion 232 is inserted into the box casting for further positioning. The positioning block 23 has various sizes. When processing box castings of different shapes and sizes, positioning blocks 23 of different sizes can be fixed on the vertical plate 22 to better process and adapt to box castings of different shapes and sizes.

[0042] Specifically, in this embodiment, the positioning block 23 is matched with the inner wall contour of the box-type casting to position it, preventing positional movement during processing, making processing easier and ensuring a high pass rate after wire reflow. The block body 231 is matched with the inner wall contour of the box-type casting, and the positioning protrusion 232 further secures the positioning.

[0043] Furthermore, as a preferred embodiment, the positioning plate 21 is equipped with multiple sliders 24, which are slidably connected to the mounting plate 1.

[0044] Furthermore, as a preferred embodiment, the mounting plate 1 is equipped with two parallel guide rails 6, the positioning device 2 is slidably mounted on the guide rails 6, and the processing device 3 is located between the two guide rails 6.

[0045] Furthermore, as a preferred embodiment, the top of the guide rail 6 is configured as an arc-shaped slide rail, and the slider 24 is slidably connected to the arc-shaped slide rail.

[0046] Specifically, in this embodiment, two guide rails 6 are laid parallel to each other along the length of the mounting plate 1. The top of the guide rail 6 is set as an arc-shaped slide rail. Four sliders 24 are set at the lower end of the positioning plate 21. Two sliders 24 are set on each guide rail 6 one in front and one behind. The sliders 24 are slidably connected to the arc-shaped slide rail, thereby driving the positioning plate 21 to slide along the mounting plate 1, thereby driving the product 5 to move closer to or away from the tapping tool 32.

[0047] Specifically, in this embodiment, a sliding connection is provided between the slider 24 and the mounting plate 1 to facilitate the positioning device 2 approaching the processing device 3 to process the product 5. The guide rail 6 allows the slider 24 to slide on it, further facilitating the movement of the positioning device 2.

[0048] Furthermore, as a preferred embodiment, the processing device 3 includes a support column 31 fixed to the mounting plate 1, a drive assembly 4 mounted on one side of the support column 31, and a tapping tool 32 disposed on the other side of the support column 31.

[0049] Furthermore, as a preferred embodiment, the drive assembly 4 includes a bearing and a rotating handle 41 rotatably connected to the bearing. The tapping tool 32 is connected to the rotating handle 41, and the rotating handle 41 drives the tapping tool 32 to rotate.

[0050] Furthermore, as a preferred embodiment, the tapping tool 32 is provided with a thread 321 and at least one chip breaker groove 322 spaced apart, the chip breaker groove 322 being spiral in shape.

[0051] Specifically, in this embodiment, a support column 31 is provided at the upper end of the mounting plate 1.

A drive assembly 4 is provided on the side of the support column 31 furthest from the positioning block 23. The drive assembly 4 consists of a drive handle and a bearing. The bearing is located inside the support column 31 and connected to the drive handle. The drive handle includes a handle part and a connecting part. The connecting part connects the bearing and the tapping tool 32. The handle part is disc-shaped and can rotate, thereby driving the connecting part and the tapping tool 32 connected to it to rotate, so as to process the machining hole 51 of the product 5.

[0052] The tapping tool 32 is provided with threads 321 that engage with the threads of the machining hole 51. The tapping tool 32 is cylindrical in shape. Two chip breaking grooves 322 are also distributed at intervals on the tapping tool 32 to collect the waste chips after machining and carry them out of the machining hole 51. The chip breaking grooves 322 are spirally arranged on the outer peripheral wall of the tapping tool 32.

[0053] Specifically, in this embodiment, a support column 31 is provided to facilitate the installation of the drive assembly 4 and the tapping tool 32, and to make it easier for the tapping tool 32 and the machined hole of the product 5 to be coaxial.
