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.

[0023] See also Figure 1-Figure 4 The utility model provides a technical solution: a tap heat treatment tool, comprising a fixed base 1, a plurality of tap holes 101 are evenly spaced on the top of the fixed base 1, a movable spring base 2 is arranged on one side of the tap hole 101, a fixed spring base 3 is arranged on the other side of the tap hole 101, two linear guide rails 4 are arranged at the bottom of both ends of the movable spring base 2, two tap jackets 5 are arranged on the side close to each other of the fixed spring base 3 and the movable spring base 2, and the two tap jackets 5 are symmetrically arranged with each other, a plurality of first springs 6 are arranged on the side close to the movable spring base 2 of one of the tap jackets 5, and a plurality of second springs 7 are arranged on the side close to the fixed spring base 3 of the other tap jacket 5, and a tightening screw component 8 is arranged on the side close to each other of the two linear guide rails 4;

[0024] The tap jacket 5 includes a semi-conical funnel 501, an arc-shaped clamping block 502 is arranged at the bottom of the semi-conical funnel 501, a limiting block 503 is arranged on the outer side of the top of the semi-conical funnel 501, and the limiting block 503 is arranged on the outer side of the bottom of the arc-shaped clamping block 502. In this example, by providing the semi-conical funnel 501, the tap is easier to enter the tap jacket 5, thereby improving the working efficiency.

[0025] The fixed base 1 is fixedly connected to the fixed spring base 3, and the fixed base 1 is fixedly connected to the linear guide rail 4. In this example, by providing the linear guide rail 4, the movable spring fixed base 801 can be moved more stably, thereby improving the stability of the device.

[0026] The tightening screw component 8 includes a screw fixing seat 801, a screw 802 and a hand wheel 803. The screw fixing seat 801 is fixedly connected to the fixed base 1. One end of the screw 802 passes through the screw fixing seat 801 and is fixedly connected to the hand wheel 803. The other end of the screw 802 is rotatably connected inside the movable spring base 2. The screw 802 is rotatably connected to the screw fixing seat 801. In this example, by rotating the hand wheel 803, the screw 802 is driven to rotate on the screw fixing seat 801, and then the movable spring fixing seat 2 is driven to further control the distance between the two tap jackets 5, so as to clamp taps of different specifications.

[0027] The movable spring base 2 is symmetrically provided with two first limiting grooves 201, and the fixed spring base 3 is symmetrically provided with two second limiting grooves 301. In this example, the first limiting grooves 201 and the second limiting grooves 301 enable the semi-conical funnel 501 to move more smoothly when clamping the tap, thereby ensuring the stability of the device.

In this example, by providing the first spring 6 and the second spring 7, the two tap chucks 5 can have a certain degree of adjustability when clamping the taps, and can clamp and fix taps of different specifications within a certain range without adjusting the movable spring base 2.

[0032] Working principle: By turning the hand wheel 803, the screw 802 is driven to rotate on the screw fixing seat 801, thereby driving the movable spring fixing seat 2, and the movable spring fixing seat 2 slides on the linear guide rail 4, and the distance between the two tap sleeves 5 is further controlled. By putting the tap into the tap sleeve 5, the tap passes through the semi-conical funnel 501 and slides between the two arc-shaped clamping blocks 502. At this time, the first spring 6 and the second spring 7 are compressed, and the limit block 503 slides inside the first limit groove 201 and the second limit groove 301. The two arc-shaped clamping blocks 502 open to clamp the tap. After completing the heat treatment, the tap is slowly ejected to complete the disassembly.
