Description

Technical Field

[0001] This utility model is applicable to the automotive manufacturing field, and in particular relates to a positioning device and welding equipment. Background Technology

[0002] In the automotive manufacturing industry, welding of automotive parts is a crucial process, and its welding quality directly affects the overall performance and safety of the vehicle.

[0003] Existing technologies for welding automotive parts, especially sheet metal parts, have the following shortcomings: Firstly, it is difficult to quickly and accurately adjust the sheet metal to the appropriate position when fixing it, resulting in excessively long welding preparation time and reduced production efficiency. Secondly, the fixing method is not stable enough; during welding, the sheet metal is prone to displacement due to vibrations or external forces, affecting welding accuracy and leading to unstable welding quality and defects such as uneven welds and incomplete welds. This not only increases the defect rate but may also pose safety hazards. Furthermore, existing fixing devices typically employ only a single fixing method, failing to flexibly adjust to different shapes and sizes of automotive sheet metal parts, thus failing to meet diverse production needs. Therefore, developing a welding device that can efficiently, stably, and flexibly fix automotive sheet metal parts is of significant practical importance.

[0004] In summary, the problems existing in the relevant technologies urgently need to be solved. Utility Model Content

Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0032] in, Figure 1 and Figure 3 The reference direction coordinate system of this utility model embodiment is given below, in conjunction with Figure 1 and Figure 3 The embodiments of this utility model will be described in the directions shown.

[0033] See Figures 1-4This utility model provides a positioning device that can be used for positioning during welding of sheet metal automotive parts. Specifically, the positioning device includes a support frame 100, a positioning component 200, and a first drive mechanism 300. The top of the support frame 100 forms a positioning support surface 104. During use, the workpiece can be placed on the positioning support surface 104 and further positioned and fixed by the positioning component 200. The positioning component 200 is disposed on at least one side of the support frame 100. The positioning component 200 includes a positioning box 201, a contacting component 202, a lifting component 203, and a transmission mechanism. The positioning box 201 is provided with a transverse guide structure and a lifting guide structure (not shown in the figure). The contacting component 202 is disposed on the transverse guide structure and can contact the workpiece on the positioning support surface 104 and move transversely along the transverse guide structure. The lifting component 203 is disposed on the lifting guide structure and extends above the positioning support surface 104. The lifting component 203 is connected to the contacting component 202 through the transmission mechanism and can descend along the lifting guide structure under the drive of the contacting component 202. The transverse guide structure and the lifting guide structure can be made of guide grooves, guide rails, guide rods, etc., which are conventional technologies in this field and will not be described in detail here.

[0034] The first driving mechanism 300 is used to drive the workpiece or positioning component 200 on the positioning support surface 104 so that the workpiece on the positioning support surface 104 abuts against the abutting component 202.

[0035] Combination Figures 1-4 The technical solution of this utility model can be used for welding and positioning workpieces such as sheet metal for automotive parts. In use, the sheet metal of the automotive part is placed on top of the support frame 100. The first drive mechanism 300 is activated to drive the workpiece or positioning component 200 on the positioning support surface 104, causing the workpiece on the positioning support surface 104 to abut against the abutting component 202. After contacting the workpiece, the abutting component 202 moves inward along the transverse guide structure. This movement of the abutting component 202 drives the transmission mechanism, which in turn drives the lifting component 203. The lifting component 203 moves downward along the lifting guide structure, pressing down on the workpiece on the positioning support surface 104. Thus, the workpiece is fixed through the pressing of the lifting component 203 and the abutting of the abutting component 202. This fixing method is simple to operate and has a good fixing effect, ensuring the workpiece remains stable during welding.

[0036] In some embodiments, see Figure 3 , Figure 4 The positioning component 200 also includes an elastic member 204, which is connected to at least one of the abutting member 202 and the lifting member 203, for driving the abutting member 202 and the lifting member 203 to automatically reset. For example, in Figure 3 , Figure 4In the embodiment shown, the elastic component 204 includes a spring supported at the bottom of the lifting component 203. After the workpiece is processed or welded, the first drive mechanism 300 releases the force, the positioning component 200 releases the workpiece, and the abutting component 202 and the lifting component 203 automatically reset under the action of the spring so as to perform the positioning of the next workpiece.

[0037] The transmission mechanism is used to transmit force and motion between the abutting component 202 and the lifting component 203. In some embodiments, see [reference needed]. Figure 3 , Figure 4 The transmission mechanism includes a first gear 205 and a second gear 206 coaxially connected and installed in the positioning box 201 via a rotating shaft. The abutting component 202 extends laterally and is provided with a first drive tooth 207 that drives and cooperates with the first gear 205. The lifting component 203 extends in the height direction and is provided with a second drive tooth 208 that drives and cooperates with the second gear 206. When positioning the workpiece, the protruding abutting component 202 of the positioning box 201 contacts the workpiece (e.g., a sheet metal). After contacting the workpiece, the abutting component 202 moves inward. The movement of the abutting component 202 drives the first gear 205 to mesh, thereby realizing the rotation of the first gear 205. The rotation of the first gear 205 drives the second gear 206 to rotate. The second gear 206 meshes with the lifting component 203, and the lifting component 203 moves downward at the same time. The lifting component 203 contacts the workpiece until the first drive mechanism 300 stops running due to a large force. At this time, the workpiece is fixed by the pressing of the lifting component 203 and the abutting of the abutting component 202.

[0038] It is understandable that the transmission mechanism can also be a wedge block engagement method, that is, the abutting component 202 is provided with a first wedge block and the lifting component 203 is provided with a second wedge block. The first wedge block of the abutting component 202 and the second wedge block of the lifting component 203 are engaged through inclined surface contact. When the abutting component 202 moves along the transverse guide structure, the first wedge block pushes against the second wedge block, thereby driving the lifting component 203 to descend along the lifting guide structure.

[0039] It is understandable that the transmission mechanism can also be driven by a slant groove, that is, a drive block is provided in the contacting part 202, the drive block is provided with an inclined groove extending at an angle, and the lifting part 203 has a guide pin embedded in the slant groove. When the contacting part 202 moves along the transverse guide structure, the guide pin moves along the slant groove of the drive block, thereby driving the lifting part 203 to descend along the lifting guide structure.

[0040] In some embodiments, see Figure 1The positioning component 200 includes a left positioning component disposed on the left side of the support frame 100 and a right positioning component disposed on the right side of the support frame 100. The first driving mechanism 300 includes a left first driving mechanism for driving the left positioning component and a right first driving mechanism for driving the right positioning component. In this embodiment, the positioning components 200 are arranged symmetrically on both sides of the support frame 100. During operation, the first driving mechanism 300 synchronously drives the corresponding positioning components 200 to position and clamp the workpiece on both sides, resulting in higher positioning efficiency and ensuring positional accuracy during workpiece positioning.

[0041] Further, see Figure 1 Multiple left-side positioning components are arranged along the front-rear direction of the support frame 100. These multiple left-side positioning components are mounted on a left-side mounting plate 101, which is positioned on the support frame 100 via a mounting plate guide structure 102. The output end of the left-side first drive mechanism 300 is connected to the left-side mounting plate 101. Similarly, multiple right-side positioning components are arranged along the front-rear direction of the support frame 100. These multiple right-side positioning components are mounted on a right-side mounting plate 103, which is positioned on the support frame 100 via a mounting plate guide structure 102. The output end of the right-side first drive mechanism 300 is connected to the right-side mounting plate 103. In this embodiment, multiple left-side and right-side positioning components are arranged along the front-rear direction of the support frame 100. This ensures multi-point positioning of the workpiece and, through cooperation with the mounting plate guide structure 102, guarantees positioning accuracy.

[0042] In some embodiments, see Figure 1 The support frame 100 has multiple ball bearings 105 on the positioning support surface 104. This allows workpieces such as sheet metal to move easily on the top of the support frame 100, facilitating quick and easy adjustment to the appropriate position, shortening welding preparation time, and improving production efficiency. This positioning and adjustment method is more flexible and efficient, and can adapt to the positioning requirements of different sheet metals.

[0043] In some embodiments, see Figure 1 , Figure 5 The support frame 100 has an adsorption assembly 400 below the positioning support surface 104. The adsorption assembly 400 includes an adsorption pad 401 and a second drive mechanism 402 that drives the adsorption pad 401 to rise and fall. A suction nozzle assembly 403 is located on the top of the adsorption pad 401. During operation, the second drive mechanism 402 drives the adsorption pad 401 to rise, allowing the suction nozzle assembly 403 of the adsorption pad 401 to adsorb the workpiece from the bottom, thus assisting in fixing the workpiece at the top and achieving auxiliary fixing. This embodiment adopts a dual fixing mechanism, combining the mechanical fixing of the contacting component 202 and the lifting component 203 with the negative pressure auxiliary fixing of the adsorption pad 401. This enhances the stability of the plate fixing, effectively avoids plate displacement during welding, and ensures welding accuracy and quality.

[0044] Further, see Figure 1 , Figure 5 The adsorption assembly 400 also includes a movable seat 404 and a third drive mechanism 405. The adsorption pad 401 and the second drive mechanism 402 are disposed on the movable seat 404. The third drive mechanism 405 is used to drive the movable seat 404 to move along the front-rear direction of the support frame 100. The third drive mechanism 405 can be a screw and nut mechanism. By controlling the moving distance of the third drive mechanism 405, the position of the movable seat 404 can be flexibly adjusted, which can meet the fixing requirements of automotive parts sheet metal of different shapes and sizes, and improve the versatility and practicality of the device.

[0045] Further, see Figure 5 The adsorption assembly 400 also includes an air pump 406, which is mounted on the movable base 404 or the lifting pad. The air pump 406 is connected to the nozzle assembly 403. In use, the air pump 406 draws air from the top of the suction pad to create negative pressure, which helps to fix the top plate of the adsorption pad 401, thus achieving the function of auxiliary fixation. In this embodiment, the air pump 406 is directly mounted on the movable base 404 or the lifting pad, which avoids the arrangement of pipelines on the entire positioning device, making the structure more compact and facilitating the adjustment of the position of the adsorption assembly 400 under the drive of the third drive mechanism 405.

[0046] After use, the suction pump 406 stops running, and the second drive mechanism 402 controls the adsorption pad 401 to descend. At the same time, the first drive mechanism 300 retracts, and the contact of the abutment component 202 also separates. Under the action of the reset spring connected to the lifting component 203, the lifting component 203 and the abutment component 202 will return to their original positions, and the workpiece is completely released. At this time, the workpiece can be taken out.

[0047] See Figure 1 An embodiment of this utility model also provides a welding device, including the positioning device in any of the above embodiments. After the workpiece is fixed by the positioning device, the welding machine at the top is used to weld the workpiece.
