[0020] Such as Figures 1 - 3As shown in the figure, a tool diameter detection device for a circuit board cutting machine includes a fixed seat 1 and a lead screw 2 rotatably connected to the lower surface of the fixed seat 1. A nut seat 3 is threadedly connected to the outer surface of the lead screw 2. A limit rod 4 is fixedly connected to the left side position of the lower surface of the fixed seat 1. A scale line 5 is provided on the outer cylindrical surface of the limit rod 4. An upper positioning rod 6 is arranged outside the nut seat 3. The lower end of the limit rod 4 is fixedly connected to a bearing seat 7, and the lead screw 2 is rotatably connected to the upper surface of the bearing seat 7. A lower positioning rod 8 is arranged below the bearing seat 7.

[0021] By adopting the above technical solution, when measuring the tool diameter of the circuit board cutting machine, this device can be inserted into the gap beside the tool, so that the lower positioning rod 8 fits the lowermost end of the tool. Rotating the lead screw 2 can make the nut seat 3 gradually descend under the action of the limit rod 4. When the upper positioning rod 6 fits the uppermost end of the tool, the position of the upper surface of the nut seat 3 relative to the scale line 5 on the outer cylindrical surface of the limit rod 4 can be observed, and then the measurement result can be obtained. This device is convenient for measuring larger tools and is also applicable to narrow gaps.

[0022] As Figures 1 - 3 shown in the figure, the upper end of the lead screw 2 is fixedly connected to a handwheel 9, and the handwheel 9 is arranged on the upper surface of the right side of the fixed seat 1. The handwheel 9 facilitates the operator to rotate the lead screw 2.

[0023] Furthermore, a handle 10 is fixedly connected to the outer surface of the left side of the fixed seat 1, and a sponge sleeve 11 is sleeved on the outer cylindrical surface of the handle 10. The handle 10 facilitates the operator to hold the fixed seat 1, and the sponge sleeve 11 can increase the comfort of holding.

[0024] Furthermore, an upper socket 12 is fixedly connected to the outer surface of the right side of the nut seat 3, and the upper positioning rod 6 is slidably connected through the inside of the upper socket 12.

[0025] Furthermore, a first screw 13 is threadedly connected to the outer surface of the upper positioning rod 6 extending from the front surface of the upper socket 12, and a knob is fixedly connected to the front end of the first screw 13.

[0026] Furthermore, a lower socket 14 is fixedly connected to the lower surface of the bearing seat 7, and the lower positioning rod 8 is slidably connected to the inside of the lower socket 14.

[0027] Furthermore, a second screw 15 is threadedly connected to the outer surface of the lower positioning rod 8 extending from the front surface of the bearing seat 7, and a knob is fixedly connected to the front end of the second screw 15.

[0028] Working principle: When using the tool diameter detection device for the circuit board cutting machine, first, when measuring the tool diameter of the circuit board cutting machine, this device can be inserted into the gap beside the tool, so that the lower positioning rod 8 fits against the lowest end of the tool. By rotating the screw rod 2, the nut seat 3 can gradually descend under the action of the limit rod 4. When the upper positioning rod 6 fits against the uppermost end of the tool, the position of the upper surface of the nut seat 3 relative to the scale line 5 on the outer cylindrical surface of the limit rod 4 can be observed, and then the measurement result can be obtained. By rotating the first screw rod 13, the tightness of the first screw rod 13 can be adjusted to facilitate the replacement of the upper positioning rod 6. By rotating the second screw rod 15, the tightness of the second screw rod 15 can be adjusted to facilitate the replacement of the lower positioning rod 8. This is the working principle of the tool diameter detection device for the circuit board cutting machine.
