DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the embodiments.

[0019] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0020] See also Figure 1-3 The utility model provides a verticality fixing device for a handheld tapping machine, comprising a handheld tapping machine body 1 and a verticality fixing assembly 2, wherein the verticality fixing assembly 2 comprises a guide clamping block 21, a guide column 22 and a spring 23, wherein the guide clamping block 21 is fixedly sleeved on the handheld tapping machine body 1, and the guide clamping block 21 is detachably connected to the handheld tapping machine body 1, wherein there are four guide columns 22, which are annularly distributed at the bottom of the guide clamping block 21, wherein a guide hole 24 is provided inside the guide clamping block 21 above each guide column 22, wherein the spring 23 is arranged in the guide hole 24, wherein the upper end of the guide column 22 slides through the guide hole 24 and is fixedly connected to a limit block 25, wherein the limit block 2 5 is in contact with the lower end of the spring 23. By setting the verticality fixing component 2, when in use, the guide clamping block 21 can be fixedly mounted on the handheld tapping machine body 1, so that the lower end of the guide column 22 is lower than the tap of the tapping machine. When tapping, the lower ends of the four guide columns 22 are pressed against the surface of the part, and then the tap of the tapping machine is used to descend for tapping. In this process, the guide column 22 slides along the guide hole 24 to guide the tap of the tapping machine. At the same time, the spring 23 is squeezed to support the guide column 22. After the tapping is completed, the spring 23 can be used to reset the guide column 22, thereby effectively solving the problem of the verticality between the tap and the end face of the part, ensuring the tapping quality and improving the work efficiency.

[0021] Specifically, the guide clamp 21 includes two arc-shaped clamps 211 hinged to each other, and the two arc-shaped clamps 211 are respectively sleeved on both sides of the hand-held tapping machine body 1, and the two arc-shaped clamps 211 are fixedly installed by fastening bolts 212. The ends of the two arc-shaped clamps 211 away from the hinge point are provided with connecting holes 213 compatible with the fastening bolts 212. By setting the arc-shaped clamps 211, the fastening bolts 212 and the connecting holes 213, the guide clamp 21 can be freely disassembled and assembled for easy use; the inner surface of the arc-shaped clamp 211 is fixedly connected with an anti-skid pad 214, and the anti-skid pad 214 is a rubber pad. By setting the anti-skid pad 214, the friction of the inner surface of the arc-shaped clamp 211 can be increased, so that the installation of the guide clamp 21 is more stable.

[0022] Furthermore, an end block 26 is inserted into the upper end of the guide hole 24, and the end block 26 is threadedly connected to the inner wall of the guide hole 24. A cross groove 261 is provided at the upper end of the end block 26. By setting the end block 26, after the end block 26 is screwed out from the upper end of the guide hole 24, the spring 23 and the guide column 22 can be taken out from the upper end of the guide hole 24, which is convenient for disassembly and assembly.

[0023] The working principle and use process of the utility model are as follows: first, by setting the verticality fixing component 2, when in use, the guide clamp 21 can be fixedly mounted on the handheld tapping machine body 1, so that the lower end of the guide column 22 is lower than the tap of the tapping machine. When tapping, the lower ends of the four guide columns 22 are against the surface of the part, and then the tap of the tapping machine is used to descend for tapping. During this process, the guide column 22 slides along the guide hole 24, guiding the tap of the tapping machine. At the same time, the spring 23 generates extrusion to support the guide column 22. After the tapping is completed, the spring 23 can be used to reset the guide column 22, thereby effectively solving the problem of the verticality of the tap and the end face of the part, ensuring the tapping quality and improving work efficiency.
