Description

Technical Field

[0001] This utility model relates to the field of welding fixtures, specifically, to a space-saving welding fixture. Background Technology

[0002] To meet the demands of modern automotive design in terms of lightweighting, safety, cost control, and manufacturing efficiency, the automotive industry typically uses welding to join parts of different materials or thicknesses into a whole.

[0003] Chinese patent number 202011071005.5 discloses a laser welding fixture for welded plates, including a base. Mounting seats are hinged to the left and right sides of the upper end of the base. A lifting cylinder connects the lower side of the mounting seat to the base. A transverse slide rail is provided on the surface of the mounting seat. A placement plate is mounted on the mounting seat, and its lower side is slidably connected to the slide rail. A pushing cylinder is located on the outer side of the mounting seat, and its output end is connected to the placement plate. The pushing cylinder can push the placement plate to slide towards the center, allowing the plates on both sides to be joined together on the welding table.

[0004] When using this method of splicing with horizontally pushing cylinders on both sides, cylinders are required on both sides. The extension and retraction of the cylinders are needed to push the plates. When the pushing distance is large, the length of the cylinders themselves is also very large, which occupies a lot of horizontal space. Although the lifting cylinder can realize the storage of the mechanisms on both sides, during operation, the lifting cylinder needs to be used to lift the mechanisms on both sides to a horizontal position, and repeated rotation will affect the connection accuracy of the hinge position and affect the relative position of the workpieces on both sides during welding. Utility Model Content

[0005] The purpose of this utility model is to provide a space-saving welding fixture, which is equipped with a first cylinder for pushing the sliding plate to extend and retract. The first cylinder is arranged along the height direction, thus saving the space occupied by the space-saving welding fixture.

[0006] To achieve the above objectives, this utility model provides a space-saving welding fixture, including a fixture body, a first cylinder, and a sliding plate slidably connected to the fixture body. The telescopic rod of the first cylinder is connected to the sliding plate, and the telescopic rod of the first cylinder controls the sliding of the sliding plate relative to the fixture body.

[0007] The first cylinder is arranged along the height direction. The bottom end of the first cylinder is rotatably connected to the tooling body. The telescopic end of the first cylinder is rotatably connected to the tooling body and the sliding plate respectively through the first connector and the second connector.

[0008] Preferably, a third connecting member is provided at the bottom of the first cylinder, and the first cylinder is connected to the tooling body through the third connecting member.

[0009] Preferably, a space-saving welding fixture further includes a first positioning fixture for positioning the first positioning element.

[0010] Preferably, the first positioning fixture includes a first positioning pin, a first pressure block, and a limiting element.

[0011] Preferably, the first pressing block and the limiting member are fixedly connected by a fixing plate.

[0012] Preferably, the fixing plate is fixedly connected to the second cylinder.

[0013] Preferably, it further includes a third positioning fixture for fixing the third positioning component, the third positioning fixture being slidably connected to the tooling body.

[0014] Preferably, the third positioning fixture includes a limiter.

[0015] Preferably, the third positioning fixture further includes a second positioning pin and a second pressure block.

[0016] According to the above technical solution, the telescopic control sliding plate of the first cylinder of this utility model slides relative to the tooling body, and a first slide rail is provided between the sliding plate and the tooling body, so that the sliding plate can slide on the tooling body through the first slide rail.

[0017] Setting the first cylinder along the height direction can make full use of the space in the height direction of the welding fixture, thereby avoiding the space-saving welding fixture occupying too much horizontal space.

[0018] The telescopic end of the first cylinder is rotatably connected to the tooling body and the sliding plate via a first connector and a second connector, respectively. The first connector is rotatably connected to the tooling body at a first connection point, and the second connector is rotatably connected to the sliding plate at a second connection point. Both the first and second connectors are rotatably connected to the telescopic end of the first cylinder. When the telescopic end extends, it pushes the first and second connectors upwards. Since the second connection point can only slide along the direction of the first slide rail, and the position of the first connection point cannot change, during the extension of the telescopic end, the first connector rotates around the first connection point. Simultaneously, the second connection point pushes the sliding plate away from the first cylinder, thus achieving a pushing effect on the sliding plate. Because the first connector needs to rotate circumferentially around the first connection point, the telescopic end of the first cylinder will rotate, and the first cylinder itself will oscillate. Therefore, the bottom of the first cylinder needs to be rotatably connected to the tooling body.

[0019] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0036] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0037] In this utility model, unless otherwise stated, directional words such as "bottom end" and "front" included in the terminology only represent the orientation of the term in its normal use state, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0038] See Figure 1The space-saving welding fixture includes a fixture body 1, a first cylinder and a sliding plate 2 slidably connected to the fixture body 1. The telescopic rod of the first cylinder 3 is connected to the sliding plate 2, and the telescopic rod of the first cylinder 3 controls the sliding of the sliding plate 2 relative to the fixture body 1.

[0039] The first cylinder 3 is arranged along the height direction. The bottom end of the first cylinder 3 is rotatably connected to the tooling body 1. The telescopic end of the first cylinder 3 is rotatably connected to the tooling body 1 and the sliding plate 2 respectively through the first connecting piece 31 and the second connecting piece 32.

[0040] Through the implementation of the above technical solution, the telescopic control sliding plate 2 of the telescopic rod of the first cylinder 3 slides relative to the tooling body 1. A first slide rail 21 is provided between the sliding plate 2 and the tooling body 1, and the sliding plate 2 can slide on the tooling body 1 through the first slide rail 21.

[0041] By setting the first cylinder 3 along the height direction, the space in the height direction of the welding fixture can be fully utilized, thereby avoiding the space-saving welding fixture occupying too much horizontal space.

[0042] The telescopic end of the first cylinder 3 is rotatably connected to the tooling body 1 and the sliding plate 2 via a first connecting member 31 and a second connecting member 32, respectively. The first connecting member 31 is rotatably connected to the tooling body 1 at the first connection point 11, and the second connecting member 32 is rotatably connected to the sliding plate 2 at the second connection point 22. The first connecting member 31 and the second connecting member 32 are rotatably connected to the telescopic end of the first cylinder 3. When the telescopic end extends, it pushes the first connecting member 31 and the second connecting member 32 upward. Since the second connection point 22 can only slide along the direction of the first slide rail 21, while the position of the first connection point 11 cannot change, during the extension of the telescopic end, the first connecting member 31 rotates around the first connection point 11. At the same time, the second connection point 22 pushes the sliding plate 2 away from the first cylinder 3, thereby achieving the pushing effect on the sliding plate 2. Since the first connecting member 31 needs to rotate circumferentially around the first connection point 11, the telescopic end of the first cylinder 3 will rotate, and the first cylinder 3 itself will swing. Therefore, the bottom of the first cylinder 3 needs to be rotatably connected to the tooling body 1.

[0043] In this manner, preferably, a third connector 33 is provided at the bottom end of the first cylinder 3, and the first cylinder 3 is connected to the tooling body 1 through the third connector 33.

[0044] By setting the third connecting piece 33, more movement space is obtained between the first cylinder 3 and the tooling body 1, so as to avoid interference between the first cylinder 3 and the tooling body 1 during the movement.

[0045] In this embodiment, preferably, a space-saving welding fixture further includes a first positioning fixture 4 for positioning the first positioning component.

[0046] The welding fixture is equipped with clamps that position multiple workpieces to be welded. After the clamps on the sliding plate 2 fix the workpieces, the workpieces are connected to the first positioning part next to them by the action of the first slide rail 21, and the robot welding gun can then weld the connection position.

[0047] The first positioning fixture is used to position the first positioning component on the welding fixture. After the first fixture completes the positioning of the first positioning component, the sliding plate 2 drives the workpiece located on it to move towards the first positioning component until the workpiece on the sliding plate 2 contacts the first positioning component.

[0048] During the process of the workpiece on the sliding plate 2 contacting the first positioning member, the workpiece on the sliding plate 2 may exert a moving impact force on the first fixing member. Therefore, the first positioning member clamp 4 needs to reliably fasten the first positioning member to ensure that the position of the first positioning member does not change during the contact process, thereby ensuring that the weld quality is qualified after the contact position is welded.

[0049] In this manner, preferably, the first positioning fixture 4 includes a first positioning pin 41, a first pressing block 42, and a limiting member 43.

[0050] To facilitate workpiece placement, the positioning pin is usually smaller than the size of the positioning hole. Therefore, after the first positioning component is engaged with the first positioning pin 41, the first positioning component can still wobble within a small range relative to the tooling body 1, and other positioning mechanisms are needed to fix the first positioning component.

[0051] The first pressure block 42 can provide pressure to the first positioning member from above. Under this pressure, when the sliding plate 2 approaches, the first fixing member does not have the degree of freedom in the height direction and cannot jump upward. However, the first positioning member may still move around, so a limiting member 43 is also needed to limit the position of the first positioning member in the horizontal direction, so as to ensure the reliable position of the first positioning member during the welding process.

[0052] Preferably, the limiting member 43 can be designed according to the shape of the workpiece. When there are two protrusions on the surface of the workpiece in the horizontal direction, the limiting member 43 can be set in the middle of the two protrusions, with both ends of the limiting member 43 engaging with the two protrusions respectively, thereby preventing the first positioning member from moving in the horizontal direction. By limiting the position of the two protrusions with the limiting member 43, the position of the first positioning member can be limited in the horizontal direction.

[0053] In this manner, preferably, the first pressing block 42 and the limiting member 43 are fixedly connected by a fixing plate 45.

[0054] The first pressure block 42 and the limiting member 43 are connected by the fixing plate 45, so that the first pressure block 42 and the limiting member 43 can be driven by the same cylinder at the same time. This can save the manufacturing cost of the welding fixture and also save space.

[0055] In this manner, preferably, the fixing plate 45 is fixedly connected to the second cylinder 44.

[0056] The second cylinder 44 is configured as a tilting cylinder. The fixed plate 45 moves in a circular motion with the swing arm of the second cylinder 44. The fixed plate 45 rotates downward with the second cylinder 44 and achieves pressing and limiting of the first fixed member at the extreme position of rotation.

[0057] In this embodiment, preferably, it further includes a third positioning fixture 5 for fixing the third positioning component, and the third positioning fixture 5 is slidably connected to the tooling body 1.

[0058] After the first positioning component is placed in place, the sliding plate 2 will move the workpiece on it until the workpiece contacts the first positioning component. Then, the third positioning component can be pushed into place by the sliding of the third positioning component clamp 5, so as to achieve splicing with the workpiece on the first positioning component and the sliding plate 2.

[0059] The third positioning fixture 5 is connected to the tooling body 1 via the second slide rail 53. Preferably, the sliding distance of the third positioning fixture 5 is small, and the third positioning fixture 5 can be pushed into place by the extension and retraction of the small cylinder.

[0060] This method allows for the splicing of three workpieces in the same location.

[0061] In this manner, preferably, the third positioning fixture 5 includes a limiter 54.

[0062] The third positioning component moves into place last, so a limiter 54 needs to be set to prevent the third positioning component clamp 5 from sliding excessively and hitting the first positioning component and the workpiece on the sliding plate 2.

[0063] In this manner, preferably, the third positioning fixture 5 includes a second positioning pin 51 and a second pressure block 52.

[0064] The second positioning pin 51 enables the basic positioning of the third positioning component. After the third positioning component is fitted onto the second positioning pin 51, the front of the third positioning component abuts against the end face of the second positioning pin 51. Through the action of the second pressing block 52, the third positioning component is held tightly between the end face of the second pressing block 52 and the second positioning pin 51.

[0065] Since the two ends of the third positioning member need to be welded to the first positioning member and the workpiece on the sliding plate 2 respectively, the first positioning member and the workpiece on the sliding plate 2, which are fixedly set at both ends of the third positioning member, can limit the third positioning member at both ends.

[0066] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0067] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0068] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
