If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0031] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application after combining the specific content of the technical solution.

[0032] Reference Figures 1 to 3The jig of the first embodiment of the present application is applied to the side C-pillar for positioning and clamping during welding, which improves the problems of multiple pressure heads, inaccurate positioning, and easy damage of the pressure head cylinder of the traditional welding jig. It is a positioning and clamping device with excellent design effect, reliable, practical, and low cost. The jig includes a plate body 100 and a clamping component 200.

[0033] The plate body 100 is formed with a mold cavity 110; the clamping component 200 includes a driving member 210, a shaft rod 220 and a plurality of positioning press heads 230, the driving member 210 is arranged on the plate body 100, the shaft rod 220 is connected to the driving member 210 and extends along a preset direction, and each positioning press head 230 is arranged on the shaft rod 220 at intervals, and the driving member 210 is suitable for driving the shaft rod 220 to rotate so that each positioning press head 230 moves synchronously to clamp or loosen the workpiece.

[0034] It is understandable that the shaft 220 has a preset length so that a plurality of positioning rams 230 are arranged on the shaft 220, and each positioning ram 230 is sequentially arranged along the extension direction of the shaft 220 so that it has a first state of pressing the workpiece and a second state of releasing the workpiece under the drive of the driving member 210. Further, by designing the structure, orientation and positions corresponding to the two states of the positioning ram 230, it is ensured that the positioning ram 230 is pressed at a non-welding point position in the pressing state, so as to achieve pressing, and the robot automatically performs welding.

[0035] Reference Figures 1 to 3 The fixture of the first aspect of the present application is characterized by arranging multiple positioning pressure heads 230 on the shaft 220, and using the driving member 210 to move the shaft 220 to simultaneously control the multiple positioning pressure heads 230, so as to achieve the effect of improving the positioning and clamping accuracy through unified control. At the same time, since the synchronous movement of each positioning pressure head 230 can be controlled by only one driving member 210, compared with the traditional method of installing multiple cylinders near the mold cavity 110, the frequency of maintenance is reduced, the maintenance cost is reduced, the abnormal time is reduced, and the spatial position can be utilized to reasonably increase the number of the fixture mold cavity 110, increase production capacity, and improve quality.

[0036] In some embodiments of the present application, the shaft 220 is disposed outside the mold cavity 110 and extends along the long side direction of the mold cavity 110, so that each positioning press head 230 is suitable for being sequentially spaced along the long side direction of the mold cavity 110. It can be understood that the long side of the mold cavity 110 corresponds to the long side of the product, and each positioning press head 230 acts on the long side of the product, thereby further ensuring the positioning and pressing effect and improving the quality.

[0037] In some embodiments, the mold cavity 110 is configured as a substantially rectangular structure, which is coordinated with the extension direction of the shaft 220 so that the product can be better arranged, thereby improving production capacity.

[0038] In some embodiments of the present application, the driving member 210 includes a rotary cylinder, which is suitable for driving the positioning pressure head 230 to switch states by forward and reverse rotation. It can be understood that the shaft 220 is driven to rotate by a high-precision rotary cylinder.

[0039] In some embodiments, the driving member 210 can also be configured as a driving device such as a servo motor for driving the shaft 220 to rotate, so that the shaft 220 can indirectly complete the positioning and pressing work through forward and reverse rotation.

[0040] In some embodiments of the present application, the pressing component 200 further includes a bearing 240, one end of the shaft 220 is connected to the rotary cylinder, and the other end of the shaft 220 is disposed on the bearing 240. It is understood that the bearing 240 can ensure that the shaft 220 can rotate smoothly, and can improve the rotation accuracy of the shaft 220, improve the driving accuracy, and ensure the positioning accuracy of each positioning pressure head 230.

[0041] In some embodiments of the present application, the pressing component 200 further includes a position detection component 250, which is suitable for detecting the position of the positioning pressure head 230. It can be understood that the position detection component 250 is used to determine whether the positioning pressure head 230 accurately presses the workpiece, ensures the accuracy of positioning and pressing on the basis of ensuring production safety, and also facilitates subsequent maintenance and debugging.

[0042] In some embodiments, the in-position detection assembly 250 includes a metal proximity sensor 251 and a metal sheet 252. The metal proximity sensor 251 is disposed on the plate body 100, and the metal sheet 252 is disposed on the shaft 220. When the positioning press head 230 reaches a preset position, the metal sheet 252 is adapted to trigger the metal proximity sensor 251. It is understandable that the metal sheet 252 rotates synchronously with the shaft 220, and the metal proximity sensor 251 is used to detect the metal sheet 252 to determine whether the positioning press head 230 is accurately in position when pressing the workpiece each time, thereby preventing the cylinder from being over-pressed.

[0043] In some embodiments, a metal proximity sensor 251 is installed on the side close to the bearing 240, and a metal sheet 252 is installed on the shaft 220. When the shaft 220 rotates until the pressure head is pressed, one side of the metal sheet 252 is parallel to the sensing plane of the metal proximity sensor 251.

[0044] In some embodiments of the present application, two clamping components 200 are provided, each clamping component 200 is respectively provided on the outside of each long side of the mold cavity 110, and each shaft 220 extends along the long side direction of the mold cavity 110. It can be understood that the two clamping components 200 cooperate with each other to position and clamp the workpiece, thereby further improving the problem of inaccurate positioning and clamping.

[0045] Furthermore, a plurality of mold cavities 110 are provided, and each mold cavity 110 is provided with two clamping components 200. It is understandable that since each positioning press head 230 is driven by a driving member 210 and a shaft 220, there is more space in the plate body 100, and a plurality of mold cavities 110 can be provided on this basis to improve production efficiency.

[0046] In some embodiments, four fetal membrane positions are designed according to the width of the workbench of the welding tooling, and one product is placed on each fetal membrane. One side of the long side of the product needs to be positioned and pressed, so two high-precision rotary cylinders are required for each product. The positioning pressure heads 230 are fixed on the shaft 220, one side of the shaft 220 is connected to the cylinder, and the other side is connected to the bearing 240 at a fixed position. The two cylinders rotate 90° in opposite directions to indirectly complete the positioning and pressing work. To prevent the cylinder from being over-pressurized, a metal proximity sensor 251 is installed on the side with the bearing 240, and a metal sheet 252 is installed on the shaft 220. When the shaft 220 is rotated until the pressure head is pressed, one side of the metal sheet 252 is parallel to the sensing plane of the metal proximity sensor 251.

[0047] It should be noted that the welding jig in the prior art is relatively bulky and requires the use of an electric forklift to change the mold, and cannot be changed manually; and the positioning pressure head 230 cannot recognize pressure. Based on this, this application is to improve the problem of inaccurate positioning and clamping of traditional multiple cylinders; to improve the problem of small number of tire mold cavities 110 and low production in the traditional model; to reduce the risk of customer complaints, thereby reducing the cost of returns, exchanges, third-party sorting, etc. The positioning and clamping accuracy is improved by uniformly controlling the positioning pressure head 230; the spatial position is utilized by rotating the pressure heads upward, so that the number of jig mold cavities 110 is increased, the production capacity is increased by 20%, and the time is saved by 20%; compared with the traditional installation of multiple cylinders near the tire membrane, the frequency of maintenance is reduced, the maintenance cost is reduced, and the abnormal time is reduced.

[0048] Specifically, in some embodiments of the present application, the newly designed fixture is composed of 4 mold cavities 110, each mold cavity 110 is connected by two rotating cylinders to the shaft arm, and 5 positioning pressure heads 230 are fixed on each shaft arm; the rotating cylinder is connected to 2 ventilation sources, one side of the shaft arm is connected to the rotating shaft of the rotating cylinder, and one side is fixed on the bearing 240; a metal proximity sensor is installed on one side of the shaft arm bearing 240 to achieve the metal proximity sensor 251 when the rotating shaft is pressed, and the metal proximity sensor 251 feedbacks a signal, and the cylinder stops rotating; after taking the parts and putting them into the fetal membrane, the two rotating cylinders on each fetal membrane use the principle of different directions of the air source to enter the rotating cylinder, so that the rotating cylinder rotates in opposite directions, and the pressure head is pressed on the non-welding point position to achieve compression, and the robot automatically performs welding. The fixture of the present application realizes 1 mold with multiple holes. The traditional puncture welding has 1 mold and 2 holes, and the welding time is about 120 seconds. The newly designed fixture saves the time of 1 time of placing and 1 time of taking, and the welding time of each mold is about 200 seconds, which increases the production capacity by 20% and saves 20% of time.

[0049] Reference Figures 1 to 3 The welding device of the second embodiment of the present application may be a welding device for automobile production, and the welding device includes a jig of the first embodiment of the present application, which sets a plurality of positioning pressure heads 230 on the shaft 220, and uses a driving member 210 to move the shaft 220 to simultaneously control the plurality of positioning pressure heads 230, thereby achieving an effect of improving positioning and clamping accuracy through unified control. Therefore, the welding device using the above structure can have better welding quality.

[0050] Reference Figures 1 to 3 The production line of the third embodiment of the present application can be a production line for automobile production. The production line includes the welding device of the second embodiment of the present application, and the welding device has the fixture of the first embodiment of the present application. By setting multiple positioning pressure heads 230 on the shaft 220, the driving member 210 is used to move the shaft 220 to control multiple positioning pressure heads 230 at the same time, and the positioning and clamping accuracy is improved through unified control. Therefore, the production line with the above welding device can reduce the frequency of maintenance, reduce maintenance costs, reduce abnormal time, and can use the spatial position to reasonably increase the number of fixture mold cavities 110, increase production capacity, and improve quality.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
