Description

Technical Field

[0001] The utility model relates to the technical field of bottom screw tapping, in particular to a bottom screw tapping tool. Background Art

[0002] Tapping machines use taps to process internal threads. Since the tapping machine was launched on the market, it has been deeply favored by users for its advantages such as lightness, flexibility and high efficiency. It avoids the limitations of lathes, drilling machines or manual tapping, and saves time and labor, is not easy to rot, and the taps are not easy to break. Its significant features have been widely praised and adopted by users. In practice, tapping large-scale threads cannot meet the size requirements in one tapping, and it must be tapped twice or three times. The accuracy of the first tapping is required to be high, and a bottom screw tapping tool is required.

[0003] The existing patent, CN210677221U, is titled "A Tapping Fixture." This utility model relates to the technical field of tapping equipment, specifically a tapping fixture comprising a base plate mounted below a tapping machine. A vertical plate is fixedly mounted on one side of the base plate. The vertical plate has an annular hole formed in the vertical direction. A support block is positioned in front of the annular hole, and a nut is positioned behind the hole. The support block and nut are connected by a screw extending through the annular hole. One end of the screw is fixed to the support block, and the other end is fixed to the nut. The support block can be slid up and down to support tapped products A of varying sizes. A positioning mandrel is fixed to the vertical plate for positioning the tapped product A. This tapping fixture is used to help a fixture secure the tapped product A. The product does not deform when subjected to force, and holes can be drilled at any angle, resulting in high economic utilization.

[0004] The positioning top plate of the above-mentioned device is made of silicone material, which can ensure that the product will not deform when subjected to force. However, during tapping, the flexible fixation of the product after being subjected to the rotational torque of tapping cannot ensure that the product posture remains unchanged, and cannot well meet people's usage needs. In response to the above situation, technical innovation is carried out based on the existing bottom screw tapping tooling. Utility Model Content

[0012] Furthermore, a screw rod 1 is threadedly connected to the bottom of the fixing plate, and a support plate is rotatably connected to the top of the screw rod 1. Rotating the screw rod 1 causes the support plate to move upward to clamp the workbench, thereby stably fixing the device.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the workpiece is placed between the clamping blocks, the screw rod 2 is rotated, and the clamping block is vertically pressed against the side of the workpiece under the restriction of the guide rod, so that the workpiece can be fixed vertically and stably, which is convenient for subsequent tapping processing. The slider slides left and right on the slide rod group 1, and the shift block moves back and forth on the slide rod group 2, so that the position of the tap is conveniently adjusted to align with the workpiece. The tap is screwed into the workpiece by rotating the handle, and the position of the bottom screw at the processing location is more accurate. Then, the tap is unscrewed in the opposite direction, and the pin is pulled out to remove the square plug from the handle, which is convenient for replacing the tap for subsequent tapping operations.

[0014] 1. This utility model uses a slider that slides left and right on the first slide bar group, and a shift block that moves forward and backward on the second slide bar group, making it easy to adjust the position of the tap to align with the workpiece. Rotating the handle screws the tap into the workpiece, making the bottom screw position at the processing location more accurate. Then, the tap is unscrewed in the opposite direction, and the square plug is removed from the handle by pulling out the pin, making it easy to replace the tap for subsequent tapping operations.

[0015] 2. The utility model puts the fixing plate onto the edge of the workbench, rotates the screw rod one to move the support plate upward to clamp the workbench, and then fixes the device stably. The workpiece is then placed between the clamping blocks, and the screw rod two is rotated. The clamping block is vertically pressed against the side of the workpiece under the restriction of the guide rod. The arc-shaped concave surface of the clamping block fits with the side of the workpiece, which makes it convenient to fix the workpiece vertically and stably, and facilitates subsequent tapping processing.
