[0022] The limiting block 8 and the limiting groove 9 are both in a "T" shape.

[0023] The surface of the limit block 8 is provided with scale lines.

[0024] When the utility model is used, the frame 18 is placed on the placement platform 1, and the position of the positioning seat 3 in the shifting groove 2 is adjusted according to the size and shape of the frame 18. The clamping position of the plug-in board 6 and the shifting groove 2 is adjusted to ensure that the positioning seat 3 is aligned with the edge of the frame 18. The turning handle 12 at the upper end of the shift screw 10 in the vertical plate 5 is turned to move the translation seat 11 up and down along the shift screw 10 and adjust it to a height suitable for clamping the frame 18. Ensure that the clamping plate 15 inside the translation seat 11 is in a proper position for subsequent clamping operations. The adjusting screw head 17 at the outer end of the translation screw 14 is turned. Since the internal threads of the two connecting tubes 16 are in opposite directions, the clamping plates 15 on the left and right sides will move toward the center and gradually clamp the frame 18. Continue to turn the adjusting screw head 17 until the clamping plate 15 firmly clamps the frame 18 to ensure that the frame 18 will not move or shake during the processing. After the frame 18 is firmly clamped, the production and processing operation of the frame 18 can be started. This device can achieve accurate positioning and firm clamping of the civil air defense door frame, thereby improving production efficiency and product quality. Example

[0025] like Figure 1-5 As shown, a positioning device for the automatic production of a frame of a civil air defense door is provided, which includes a placing platform 1, a shifting groove 2 is provided on the side of the placing platform 1, a positioning seat 3 is movably provided inside the shifting groove 2, a horizontal plate 4 is provided on the lower side of the positioning seat 3, the horizontal plate 4 is clamped with the shifting groove 2 through a plug-in plate 6, a vertical plate 5 is provided above the horizontal plate 4, a shift mechanism is provided inside the vertical plate 5, the shift mechanism includes a shift screw 10 and a translation seat 11, the shift screw 10 passes through the vertical plate 5, a turning handle 12 is provided at the upper end of the shift screw 10, the translation seat 11 is screwed with the shift screw 10 through a collar 13, a translation screw 14 is provided inside the translation seat 11, an adjusting screw head 17 is provided at the outer end of the translation screw 14, and clamps 15 are symmetrically provided on the left and right sides of the translation screw 14, the two clamps 15 are screwed with the translation screw 14 through a connecting tube 16, and the internal threads of the two connecting tubes 16 are in opposite directions.

[0026] For better effect, a roller 7 is arranged at the bottom of the plug board 6. The roller 7 can reduce the friction between the plug board 6 and the shifting groove 2, so that the plug board 6 can move along the shifting groove 2.

[0027] For better effect, the surface of the horizontal plate 4 is provided with a limit block 8, and the bottom of the vertical plate 5 is provided with a limit slot 9. The limit block 8 is clamped in the limit slot 9, so that the vertical plate 5 can move along the horizontal plate 4 according to specific conditions.

[0028] For better effect, the limiting block 8 and the limiting groove 9 are both in a "T" shape.

[0029] For better effect, scale lines are provided on the surface of the limit block 8. The scale lines facilitate confirmation of the position of the vertical plate 5.

[0030] For better effect, the placement platform 1 can be provided with a shifting groove 2 in one or more directions selected from the four directions of front, back, left, and right, and different numbers of positioning seats 3 can also be selected to be provided inside the shifting groove 2 .

[0031] For better effect, a locking mechanism 19 is arranged inside the horizontal plate 4, and the locking mechanism 19 includes a rack 20 and a pressure plate 21. The rack 20 is fixedly arranged inside the shifting groove 2, and a locking tooth 22 is arranged on the inner side of the pressure plate 21. The locking tooth 22 is meshed with the rack 20, and a button 23 is arranged on the lower side of the pressure plate 21.

[0032] For better effect, a return spring 24 is arranged above the pressing plate 21. The return spring 24 has a force to move the pressing plate 21 downward.

[0033] When the utility model is used, the frame 18 is placed on the placement platform 1, and the position of the positioning seat 3 in the shifting groove 2 is adjusted according to the size and shape of the frame 18. The clamping position of the plug-in board 6 and the shifting groove 2 is adjusted to ensure that the positioning seat 3 is aligned with the edge of the frame 18. The turning handle 12 at the upper end of the shift screw 10 in the vertical plate 5 is turned to move the translation seat 11 up and down along the shift screw 10 and adjust it to a height suitable for clamping the frame 18. Ensure that the clamping plate 15 inside the translation seat 11 is in a proper position for subsequent clamping operations. The adjusting screw head 17 at the outer end of the translation screw 14 is turned. Since the internal threads of the two connecting tubes 16 are in opposite directions, the clamping plates 15 on the left and right sides will move toward the center and gradually clamp the frame 18. Continue to turn the adjusting screw head 17 until the clamping plate 15 firmly clamps the frame 18 to ensure that the frame 18 will not move or shake during the processing. After the frame 18 is firmly clamped, the production and processing operation of the frame 18 can be started. Furthermore, in order to prevent the positioning seat 3 from accidentally shaking and shifting during production and processing, a locking mechanism 19 is provided inside the horizontal plate 4. When the positioning seat 3 is placed normally, the reset spring 24 is in a compressed state, and the reset spring 24 will push the pressure plate 21 downward, so that the latching teeth 22 and the rack 20 are engaged with each other. At this time, the positioning seat 3 cannot move along the shifting groove 2; when the positioning seat 3 needs to be shifted, the pressure plate 21 is pushed upward by the button 23, and the latching teeth 22 and the rack 20 are separated from each other, and the limiting effect is released. At this time, the positioning seat 3 can move freely. The position of the pressure plate 21 does not affect the position of the plug-in board 6. This device can realize the precise positioning and stable clamping of the civil defense door frame, and improve production efficiency and product quality.
