DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0023] For example, please refer to Figure 1-4 , an automatic distance-fixed hot riveting welding machine, comprising a base 10, a scale 11 is provided on one side of the top of the base 10, a welding device 20 is connected to one side of the top of the base 10, and a distance-fixing device 30 is connected to the top of the base 10, and the distance-fixing device 30 comprises a limit block 32 slidably connected to both sides of the base 10, a rotating motor 31 connected to one side of the limit block 32, a fixed shaft 34 connected to the driving end of the rotating motor 31 and a gear 33 connected to both sides of the fixed shaft 34, the bottom of the gear 33 is meshed with a rack 36, and the bottom of the rack 36 is connected to the base 10;

[0024] The two sides of the fixed shaft 34 are connected to sliders 35 , and the sliders 35 are slidably connected to the base 10 . The top of the slider 35 on one side is connected to a C-shaped pointer 37 , the bottom of the slider 35 is connected to a support plate 38 , and the top of the support plate 38 is connected to a fixing mechanism 40 .

[0025] It should be noted that, in the embodiment, the rotating motor 31 drives the fixed shaft 34 and the gear 33 to rotate, so that the gear 33 rolls through the engagement of the gear 33 with the rack 36, and then the limit block 32 slides, thereby adjusting the position of the support plate 38 and the C-shaped pointer 37, and measuring the distance by pointing the C-shaped pointer 37 to the scale 11, which is convenient for the device to determine the distance.

[0026] For example, please refer to Figure 2-4 The fixing mechanism 40 includes an L-shaped plate 41 connected to multiple corners of the top of the support plate 38 and a threaded rod 42 connected to one side of the L-shaped plate 41.

[0027] It should be noted that, in the embodiment, the threaded rod 42 is rotated to make the threaded rod 42 descend, so that the threaded rod 42 fixes the workpiece.

[0028] For example, please refer to Figure 2 and Figure 4 A C-shaped frame 13 is fixed to one side of the top of the base 10, and the top of the C-shaped frame 13 is connected to a welding device 20. The welding device 20 includes a mechanical arm 21 connected to the top of the C-shaped frame 13 and a welding head 22 connected to the bottom of the mechanical arm 21.

[0029] It should be noted that, in the embodiment, the robot arm 21 is convenient for adjusting the position of the welding head 22 so as to facilitate the welding by the welding head 22 .

[0030] For example, please refer to Figure 3 A rubber pad 421 is installed at the bottom of the threaded rod 42.

[0031] It should be noted that, in the embodiment, the rubber pad 421 increases the friction between the threaded rod 42 and the workpiece, prevents the workpiece from moving, and prevents the threaded rod 42 from leaving clamping marks on the surface of the workpiece.

[0032] For example, please refer to Figure 4 The bottom of the support plate 38 is rotatably connected to a plurality of rollers 381, and the rollers 381 are evenly distributed.

[0033] It should be noted that, in the embodiment, the roller 381 reduces the friction between the support plate 38 and the base 10 , making it easier for the support plate 38 to slide.

[0034] For example, please refer to Figure 3 , a plurality of limiting grooves 12 are provided on both sides of the top of the base 10;

[0035] The limiting block 32 has limiting protrusions 321 fixed on the upper and lower sides thereof. The limiting protrusions 321 are slidably connected to the groove body of the limiting groove 12 .

[0036] It should be noted that, in the embodiment, the limiting groove 12 limits the position of the limiting block 32 , and the limiting protrusion 321 enhances the stability of the limiting block 32 to prevent the limiting block 32 from deflecting during movement.

[0037] For example, please refer to Figure 3-4 A knob 422 is fixed on the top of the threaded rod 42 , and a plurality of anti-slip grooves are provided on the outer wall of the knob 422 .

[0038] It should be noted that, in the embodiment, the knob 422 facilitates manual rotation of the threaded rod 42 , and the anti-slip groove increases the friction between the knob 422 and the manual rotation.

[0039] The specific operation mode of the utility model is as follows:

[0040] The above-mentioned automatic distance-fixing hot riveting welding machine places the workpiece on the top of the support plate 38 and aligns it, rotates the threaded rod 42 to make the threaded rod 42 descend and fix the workpiece, and drives the fixed shaft 34 and the gear 33 to rotate by rotating the motor 31, so that the gear 33 rolls through the engagement of the gear 33 and the rack 36, and then the limit block 32 slides, so as to adjust the position of the support plate 38 and the C-shaped pointer 37, and measure the distance by pointing the C-shaped pointer 37 to the scale 11, which is convenient for the device to fix the distance, and then adjust the position of the welding head 22 through the mechanical arm 21, so that the welding head 22 can perform welding.

[0041] The above-described embodiments only express the implementation methods of the present application, but for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
