DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0021] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0022] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0023] like Figure 1As shown, an embodiment of the utility model is a semi-automatic tapping machine for a vehicle frame, comprising a fixed plate 1, a frame 2 and a first tapping device 3 arranged on the frame 2, wherein the first tapping device 3 comprises a servo motor 4 and a first tap 5, the frame 2 is provided with a control button 6, a tapping platform 7 and a processing platform 8 for placing the fixed plate 1, the frame 2 is also provided with a first guide rail 9 for moving the processing platform 8, the tapping platform 7 is provided with a second tapping device 10 with the same structure as the first tapping device 3, the first tap 5 of the first tapping device 3 faces the top surface of the fixed plate 1, and the second tap of the second tapping device 10 faces the side surface of the fixed plate 1. The utility model adopts a semi-automatic structure equipment to tap the fixed plate. It only needs to place or remove the fixed plate to be tapped or the tapped plate is placed on the processing platform, that is, loading and unloading. The control button controls the tapping process with one click. After pressing the control button, the first guide rail first drives the processing platform with the fixed plate to move to the correct tapping position, and the first tapping device and the second tapping device start to tap the holes to be tapped on the top surface and the side surface of the fixed plate. After the tapping is completed, the processing platform returns to the initial position, eliminating the manual tapping process. The tapping position is fixed, and the utility model has the advantages of high tapping efficiency and excellent tapping quality.

[0024] like Figure 1 As shown, the frame 2 is also provided with a second guide rail 11 for the tapping platform 7 to move, and the second guide rail 11 is perpendicular to the axis of the first guide rail 9. Through the above structure, the tapping platform moves through the second guide rail, and the position of the second tapping device is adjusted to adapt to fixed plates of various specifications.

[0025] like Figures 2 to 3 As shown, the processing platform 8 is provided with a support shaft 12, a positioning block 13 and a positioning plate 14. One end of the support shaft 12 abuts against the processing platform 8 and the other end abuts against the fixed plate 1. One end of the positioning block 13 is clamped with the processing platform 8 and the other end is clamped with the fixed plate 1. The positioning plate 14 is extended with at least two positioning protrusions 15. The fixed plate 1 is provided with a square opening 16. One end of the positioning plate 14 is clamped with the processing platform 8 and the other end is clamped with the inner corner of the square opening 16 through the two positioning protrusions 15. Through the above structure, the processing platform supports the fixed plate through the support shaft, and the fixed plate is clamped with the processing platform through the positioning block. At the same time, the positioning protrusion of the positioning plate is clamped with the square opening of the fixed plate. The stability of the fixed plate placed on the processing platform is greatly improved through the cooperation of the three. The processing platform can drive the fixed plate to move steadily. The cooperation of the positioning block and the positioning plate limits the placement position of the fixed plate. The servo motor will only drive the tap to telescopically tap. Therefore, it is ensured that the fixed plate is placed in the same position each time, so that the tapping can be ensured in place.

[0026] like Figure 2 and Figure 5As shown, the processing platform 8 is provided with a clamping device at the position corresponding to the square opening 16, and the clamping device includes a cylinder 17, a pressure plate 18, a first connecting plate 19, and a bracket 20 fixedly connected to the cylinder 17. The cylinder 17 drives a telescopic push block 21, one end of the first connecting plate 19 is hinged to the bracket 20 and the other end is hinged to the middle of the pressure plate 18, and the push block 21 drives the pressure plate 18 to rotate around the first connecting plate 19. When the cylinder 17 drives the push block 21 to extend, the pressure plate 18 rotates around the first connecting plate 19 until the end of the pressure plate 18 away from the push block 21 abuts against the top surface of the fixed plate 1. The fixed plate is further restricted by the clamping device of the processing platform, that is, similar to the principle of a lever, one end of the pressure plate is lifted by the push block driven by the cylinder, and the other end rotates around the first connecting plate and presses down, and finally presses the fixed plate to achieve the clamping effect, further satisfying the synchronous movement of the fixed plate when the processing platform moves, and reducing the vibration of the fixed plate during tapping, ensuring good tapping quality.

[0027] like Figure 5 As shown, the clamping device further includes a second connecting plate 22 and a third connecting plate 23, one end of the second connecting plate 22 is hinged to the push block 21 and the other end is hinged to the pressing plate 18, and one end of the third connecting plate 23 is hinged to the push block 21 and the other end is hinged to the middle of the first connecting plate 19. The second connecting plate and the third connecting plate, both of which are hinged to the push block, increase the rotation range of the pressing plate. When the push block contracts, the pressing plate is retracted to the bottom of the fixed plate. When the push block extends, it drives the pressing plate to extend from the square opening and rotate to the top of the fixed plate, further improving the stability of the pressing plate, and the pressing plate firmly presses the fixed plate.

[0028] like Figure 5 As shown, the hinged ends of the first connecting plate 19, the second connecting plate 22 and the third connecting plate 23 are all provided with a retaining spring 24. The retaining spring is used to improve the stability of the connection at the hinge and prevent the parts from falling off.

[0029] like Figure 4 As shown, the positions of the frame 2 corresponding to the first guide rail 9 and the second guide rail 11 are provided with buffer brackets 25 for buffering the processing platform 8 and the tapping platform 7 respectively. The buffer brackets 25 corresponding to the first guide rail 9 and the second guide rail 11 are distributed at both ends of the stroke. The processing platform and the tapping platform are limited and buffered by the buffer bracket to prevent the processing platform and the tapping platform from sliding too far or too fast, and to protect the processing platform and the tapping platform from moving within the set stroke and stopping smoothly, thereby ensuring the accuracy of subsequent tapping.

[0030] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
