Detailed implementation manners

[0056] The technical solutions of the present invention will be further described in detail below in conjunction with the specific implementation manners.

[0057] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0058] Embodiment 1:

[0059] A component welding device with adjustable welding trajectory, as Figure 1-6 shown, includes:

[0060] A welding mechanism for welding operations;

[0061] A trajectory adjustment mechanism for adjusting the welding trajectory;

[0062] A vehicle mechanism for conveying workpieces to be welded;

[0063] A conveying mechanism for conveying the vehicle mechanism;

[0064] A control module that, based on a trajectory adjustment mechanism, realizes trajectory control of the welding mechanism;

[0065] The vehicle mechanism includes a vehicle 26, on which a fixture assembly is mounted, and a first ball head bracket 28 and a second ball head bracket 37 are respectively arranged at both ends of the fixture assembly;

[0066] The welding mechanism includes a welding assembly 19 and a position adjustment assembly for adjusting the position of the welding assembly 19, and a carriage spring 15 is arranged on the position adjustment assembly;

[0067] The trajectory adjustment mechanism includes a linkage part and a distance measurement part. The two distance measurement parts are located on both sides of the carriage spring 15 for detecting the position of the carriage spring 15. The linkage part is located on the movement paths of the first ball head bracket 28 and the second ball head bracket 37. Based on the pushing of the first ball head bracket 28 and the first clamping plate 27 on the linkage part, the distance between the distance measurement part and the carriage spring 15 is changed;

[0068] By setting structures such as the vehicle mechanism and the trajectory adjustment mechanism, the vehicle mechanism can be used to fix the workpiece to be welded, making its welding surface face upward. Based on the conveying of the conveying mechanism, the vehicle mechanism is conveyed to the welding position. During this period, the first ball head bracket 28 and the first clamping plate 27 push the linkage part, changing the distance between the distance measurement part and the carriage spring 15. One of the two distance measurement parts serves as the starting point distance measurement part, and the other serves as the ending point distance measurement part. The control module controls the welding mechanism to move towards the starting point distance measurement part based on the information of the two distance measurement parts until the value detected by the starting point distance measurement part is the preset value; then, the welding mechanism performs welding operations until the value detected by the ending point distance measurement part is the preset value, indicating that the carriage spring 15 has moved to the specified position, and the welding is completed;

[0069] This method automatically adjusts the movement distance of the welding assembly 19 in the welding mechanism based on the actual clamping situation of the fixture assembly, achieving the purpose of automatically adjusting the welding trajectory and being able to adapt to parts of different widths.

[0070] For the convenience of clamping treatment; as Figure 5 、 Figure 6 shown, the fixture assembly includes:

[0071] A first clamping plate 27 is fixed on the vehicle 26. A first sleeve 31 is installed on one side of the first clamping plate 27, and one end of the first ball head bracket 28 is installed in the first sleeve 31;

[0072] The fixed plate 38 is fixed to the top of the carrier 26. A second sleeve is provided on one side of the fixed plate 38. The second ball head holder 37 is slidably connected to the inner wall of the second sleeve. A clamping spring 35 is connected between the second ball head holder 37 and the fixed plate 38. A second fixing knob 35 for fixing the second ball head holder 37 is connected to the second sleeve by a thread.

[0073] Anti-slip pads 39 are provided on the adjacent sides of the second clamping plate 34 and the first clamping plate 27.

[0074] By providing the fixture assembly, since the first clamping plate 27 is fixedly arranged and the second clamping plate 34 is a free end, the controllability of the welding point can be ensured. The fixture assembly can be used to clamp the workpiece to be welded. After clamping, the second ball head holder 37 is fixed by the second fixing knob 35. The fixed position of the second ball head holder 37 changes based on the size of the workpiece to be welded, so that the final welding trajectory meets the welding requirements of the workpiece to be welded with the current size.

[0075] For more flexible adjustment; as Figure 5 shown, one end of the first ball head holder 28 is slidably connected to the first sleeve 31. A first fixing knob 30 for fixing the first ball head holder 28 is connected to the first sleeve 31 by a thread. Scale lines 29 are provided on the first ball head holder 28.

[0076] By providing the adjustable first ball head holder 28, the position of the first ball head holder 28 can be adjusted according to requirements, so as to achieve the purpose of adjusting the welding starting point.

[0077] In addition, since the carrier mechanism and the conveying mechanism are used in cooperation to convey the workpiece to be welded, the next workpiece to be welded can be clamped during the current welding process, and the first ball head holder 28 can be adjusted specifically according to the welding requirements of the workpiece to be welded, improving the processing efficiency.

[0078] To facilitate the adjustment of the position of the welding assembly 19; as Figure 2 [[ID=H22]]、 Figure 3 shown, the position adjustment assembly includes:

[0079] A support frame 3, on which a translation guide rail 9 is installed.

[0080] A translation drive motor 4 is installed at one end of the translation guide rail 9. The output end of the translation drive motor 4 is drivingly connected to a translation control screw 11. The translation seat 25 is connected to the outer wall of the translation control screw 11 by a thread. The translation seat 25 slides in the translation guide rail 9. A carriage spring 15 is fixed to the translation seat 25.

[0081] A lifting part is installed on the outer wall of one side of the translation seat 25, and the welding assembly 19 is installed on the lifting part.

[0082] For facilitating the adjustment of the height of the welding assembly 19; as Figure 3 、 Figure 4 shown, the lifting part includes:

[0083] Lifting guide rails 12, which are installed on the outer wall of one side of the translation seat 25;

[0084] Lifting drive motor 13, which is installed on the lifting guide rail 12, and a lifting control screw 21 is connected to the output end of the lifting drive motor 13 in a transmission manner;

[0085] Lifting seat 18, which slides up and down in the lifting guide rail 12, and the lifting seat 18 is connected to the outer wall of the lifting control screw 21 by threads, and the welding assembly 19 is installed on the outer wall of one side of the lifting seat 18;

[0086] By setting the position adjusting assembly, it is possible to drive the movement of the welding assembly 19 based on the operation of the translation drive motor 4 and the lifting drive motor 13 to achieve welding.

[0087] For facilitating the detection of the carriage spring 15; as Figure 3 、 Figure 4 shown, the distance measuring part includes:

[0088] Sliding seat 10, a translation chute 23 is formed on the translation guide rail 9, the sliding seat 10 slides in the translation chute 23, the bottom of the sliding seat 10 penetrates through the translation guide rail 9, but the sliding seat 10 does not contact the translation control screw 11;

[0089] Distance measuring sensor assembly 14, which is installed on the sliding seat 10, and the position of the distance measuring sensor assembly 14 is adapted to that of the carriage spring 15;

[0090] Casing 24, which is installed at the bottom of the sliding seat 10.

[0091] For reliable linkage; as Figure 2 [[ID=??]]、 Figure 4 shown, the linkage part includes:

[0092] Side brackets 16, two side brackets 16 are symmetrically arranged;

[0093] Carriage 6, which slides on the inner wall of the side bracket 16, and the carriage 6 and the side bracket 16 are connected by a carriage spring 15;

[0094] Guide plate 7, which is fixed to one end of the carriage 6, a guide groove 17 adapted to the ends of the first ball head bracket 28 and the second ball head bracket 37 is formed on the adjacent side of the two guide plates 7, the guide plate 7 includes a vertical section and an inclined section, the vertical sections of the two guide plates 7 are arranged in parallel, and the inclined sections of the two guide plates 7 are in an "eight" - shaped structure; It should be noted that there seems to be a mistake in the original text where "??" is used instead of a proper symbol or text in line ID 38. This has been left as is in the translation for the sake of following the original text exactly.

[0095] The linkage rod 8 is fixed to the guide plate 7, and one end of the linkage rod 8 is inserted into the sleeve 24;

[0096] By providing the linkage part and the distance measuring part, during the conveyance of the vehicle 26, the first ball head bracket 28 and the second ball head bracket 37 can be used to squeeze the two guide plates 7, and then the slide seat 10 can be moved by the linkage rod 8, so as to ultimately achieve the purpose of adjusting the trajectory.

[0097] To improve the reliability of conveyance; as Figure 1 and Figure 5 and Figure 6 shown, the conveying mechanism includes:

[0098] A conveying frame 1, on which a chain plate conveying assembly 2 is installed;

[0099] Conveying plates 5 are equidistantly installed on the chain plates of the chain plate conveying assembly 2.

[0100] To improve the reliability of conveyance; as Figure 1 and Figure 5 and Figure 6 shown, evenly distributed grooves 32 are formed on the outer wall of one side of the conveying plate 5, and a positioning toothed plate 33 adapted to the grooves 32 is provided on the outer wall of one side of the vehicle 26. When the vehicle 26 is conveyed, the positioning toothed plate 33 is snapped into the grooves 32;

[0101] By providing structures such as the conveying plate 5, the grooves 32, and the positioning toothed plate 33, the vehicle 26 can be effectively limited, preventing the structure from skewing during conveyance and improving the reliability.

[0102] To perform welding operations flexibly; as Figure 5 shown, a mounting frame 22 is fixed to the outer wall of one side of the translation guide rail 9, and a laser detection assembly 20 is provided on the mounting frame 22. The output end of the laser detection assembly 20 is located on the movement path of the grooves 32;

[0103] The grooves 32 are linearly distributed and are sequentially numbered. The laser detection assembly 20 is electrically connected to the control module. When the grooves 32 and the positioning toothed plate 33 pass through the bottom of the laser detection assembly 20, the laser detection assembly 20 transmits the detection result to the control module based on real-time detection. The control module controls the welding mechanism based on the detection result of the laser detection assembly 20 and the measurement value of the distance measuring sensor assembly 14;

[0104] Specifically, based on the cooperation between the grooves 32 and the positioning toothed plate 33, compensation for the lateral distance or longitudinal distance of the welding trajectory is achieved;

[0105] Suppose the number of grooves 32 is 10 and the number of positioning tooth plates 33 is 3. When the laser detection component 20 measures the distance, there are significant differences in the feedback values at the grooves 32 with the positioning tooth plates 33 and at the grooves 32 without the positioning tooth plates 33. Based on the feedback information, for example, when the 3 positioning tooth plates 33 are stuck in the 4th, 5th, and 6th grooves 32, it can be recorded as "0001110000", and when the 3 positioning tooth plates 33 are stuck in the 7th, 8th, and 9th grooves 32, it can be recorded as "0000001110". Each 10-digit number can correspond to a compensation scheme. For example, "0001110000" corresponds to a horizontal translation of -5 cm on the basis of the original welding track, and "0000001110" corresponds to a vertical movement of 3 cm on the basis of the original welding track, and so on;

[0106] In this way, more delicate adjustment of the welding track is realized. In operation, it is easier to distinguish and process workpieces to be welded with different requirements, which is fast and efficient.

[0107] Regarding the information that can be obtained without doubt from the drawings of the specification, not too much elaboration has been made. For example, the shape of the structure: "spherical", "rod-shaped", "with openings", etc.; and for the parts not fully disclosed in the present invention, those skilled in the art can ensure the smooth implementation of the solution of the present invention based on common sense, normal thinking logic and the prior art.

[0108] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
