[0065] The expansion support assembly 16 is mounted on the base 11 and includes a plug assembly that can move in a horizontal direction. The plug assembly is used to tighten the workpiece 15.

[0066] The pressing assembly 17 is installed on the base 11 and is used to press the workpiece 15 downward.

[0067] The technical effect of this solution is that: this solution can achieve mechanized pressing of the workpiece 15 and can improve the pressing efficiency of the workpiece 15.

[0068] Furthermore, the workpiece 15 includes:

[0069] The bottom plate 18 has side plates 19 fixed vertically to its edges;

[0070] A first top plate 20 , the first top plate 20 is parallel to the bottom plate 18 , and the first top plate 20 is disposed at one end of the bottom plate 18 ;

[0071] A second top plate 21, which is parallel to the bottom plate 18 and is disposed at the other end of the bottom plate 18;

[0072] The first top plate 20 and the second top plate 21 are used to be welded to an end of the side plate 19 away from the bottom plate 18, and a distance is left between the first top plate 20 and the second top plate 21;

[0073] Positioning holes are respectively provided on the first top plate 20 and the second top plate 21 .

[0074] The bottom plate 18 and side plates 19 are pre-welded together. The clamping device in this embodiment is used to clamp the first top plate 20 and the second top plate 21 against the side plates 19. In this embodiment, positioning holes are provided on the bottom plate 18. The positioning assembly 14 is inserted into the positioning holes of the bottom plate 18 and the first top plate 20, and the positioning assembly 14 is inserted into the positioning holes of the bottom plate 18 and the second top plate 21.

[0075] The bottom plate 18 is provided with four positioning holes, the first top plate 20 is provided with two positioning holes, and the second top plate 21 is provided with two positioning holes.

[0076] Two positioning holes on the bottom plate 18 are coaxially arranged with the positioning holes on the first top plate 20 , and the other two positioning holes on the bottom plate 18 are coaxially arranged with the positioning holes on the second top plate 21 .

[0077] As an implementation of this embodiment, the expansion assembly 16 includes two plug assemblies, which are arranged between the first top plate 20 and the second top plate 21. One plug assembly is used to tighten the first top plate 20, and the other plug assembly is used to tighten the second top plate 21.

[0078] The two plug assemblies of the expansion assembly 16 in this solution are used to squeeze the first top plate 20 and the second top plate 21 respectively, thereby pressing the first top plate 20 and the second top plate 21 in the horizontal direction.

[0079] As an implementation of this embodiment, the expansion assembly 16 includes:

[0080] The transverse mounting seat 22 is mounted on the base 11.

[0081] The fixed plate 23 is arranged on the top of the transverse mounting seat 22, and the two block assemblies are mounted on the fixed plate 23 through the first slide rail assembly 24;

[0082] The first driving member has the same number as the block assemblies, and each first driving member is used to control the movement of a block assembly.

[0083] Furthermore, the first driving member includes a first telescopic member 25, which is mounted on the transverse mounting seat 22. The top of the piston rod of the first telescopic member 25 passes through the avoidance opening of the fixed plate 23 and extends upward. The piston rod of the first telescopic member 25 is hinged to the slider in the first slide rail assembly 24 through the hinge arm 26.

[0084] When the length of the piston rod of the first telescopic member 25 is insufficient, an extension arm is installed on the piston rod of the first telescopic member 25 , and is rotatably connected to the hinge arm 26 via the extension arm.

[0085] The number of the transverse mounting seats 22 is the same as the number of the first telescopic members 25 .

[0086] The first driving member in this solution is in the form of a first telescopic member 25, and the extension direction of the first telescopic member 25 is arranged along the vertical direction. The slider in the first slide rail assembly 24 is driven by setting an articulated arm 26. This method can save the space occupied by the first driving member.

[0087] If other methods are used, a large area will be occupied in the horizontal direction, and other drive forms are not convenient to be arranged in the gap between the first top plate 20 and the second top plate 21. This structure of the present solution drives the articulated arm 26 to move through the cylinder, thereby controlling the movement of the slider in the first slide rail assembly 24.

[0088] The plug assembly includes a horizontal arm 27 and a plug portion 28. The horizontal arm 27 is mounted on the slider of the first slide rail assembly 24, and the plug portion 28 is mounted on the end of the horizontal arm 27.

[0089] The plug portion 28 in one plug assembly is used to compress the first top plate 20 , and the plug portion 28 in the other plug assembly is used to compress the second top plate 21 .

[0090] As an implementation of this embodiment, the positioning assembly 14 includes two groups of positioning modules, each group of positioning modules includes a first positioning pin 29 and a second positioning pin 30 , and the height of the first positioning pin 29 is greater than that of the second positioning pin 30 .

[0091] One group of positioning modules is used to position the first top plate 20 , and the other group of positioning modules is used to position the second top plate 21 .

[0092] This scheme adopts a high locating pin and a low locating pin.Wherein, the first locating pin 29 can penetrate to the top of the base plate 18, and the second locating pin 30 is only used for positioning the first top plate 20 or the second top plate 21.

[0093] When the workpiece 15 is positioned, the bottom plate 18, the first top plate 20 and the second top plate 21 are locked by two positioning pins. Among them, the two first positioning pins 29 provided on the bottom plate 18 are located at the diagonal position of the bottom plate 18.

[0094] Furthermore, the top ends of the first positioning pin 29 and the second positioning pin 30 are chamfered. The first positioning pin 29 or the second positioning pin 30 can be a round pin or a diamond pin.

[0095] As an implementation method of this embodiment, the support assembly 13 includes

[0097] A lifting assembly 34 is mounted on the vertical arm 32 and has an output end that moves in a vertical direction;

[0098] A support module 35 , which is mounted on the output end of the lifting assembly 34 and is used to support the workpiece 15 ;

[0099] The exit module 36 is installed below the support module 35 and has an output end that moves in a vertical direction;

[0100] The first positioning pin 29 is fixed on the supporting module 35 , and the second positioning pin 30 is provided on the output end of the exiting module 36 . The top end of the second positioning pin 30 can slide through the supporting module 35 in a vertical direction and extend upward.

[0101] The technical effect of this solution is that after the workpiece 15 is welded, the support assembly 13 returns to its initial state, and under the action of the expansion assembly 16, the output end of the lifting assembly 34 drops to a preset height. At this time, the second positioning pin 30 is separated from the workpiece 15, and the first positioning pin 29 remains in the positioning hole of the workpiece 15, which serves to limit the workpiece 15. At this time, the worker can take out the workpiece 15 more easily.

[0102] As an implementation of this embodiment, the number of support assemblies 13 is the same as the number of positioning modules.

[0103] As an implementation of this embodiment, the lifting assembly 34 includes:

[0104] A second slide rail assembly 37 , the second slide rail assembly 37 is mounted on the vertical arm 32 in a vertical direction;

[0106] The second telescopic member 39 is mounted on the bottom of the vertical arm 32 via a support and is used to drive the connecting base 38 to move up and down. The second telescopic member 39 is a pneumatic or hydraulic cylinder. The piston rod of the second telescopic member 39 is hinged to the lower end of the connecting base 38.

[0107] Furthermore, the exit module 36 adopts a third telescopic member, and the third telescopic member adopts a pneumatic cylinder or a hydraulic cylinder.

[0108] As an implementation of this embodiment, the connecting base 38 is connected to the supporting module 35 via a first adjusting washer 40. The connecting base 38 and the supporting module 35 are connected via bolts, and the first adjusting washer 40 is located between the connecting base 38 and the supporting module 35.

[0109] As an implementation of this embodiment, the support module 35 includes:

[0110] A first support base 41, the first support base 41 is mounted on the connecting base 38 through a first adjusting gasket 40;

[0111] A second support base 42 , the second support base 42 is mounted on the first support base 41 through a second adjusting gasket 43 ;

[0112] The support block 44 is mounted on the second support seat 42 through a third adjusting gasket 45 , and an avoidance hole is provided on the support block 44 .

[0113] The second support seat 42 and the first support seat 41 are connected by bolts, and the second adjustment gasket 43 is located between the second support seat 42 and the first support seat 41 .

[0114] The support block 44 and the second support seat 42 are connected by bolts, and the third adjustment gasket 45 is located between the support block 44 and the second support seat 42 .

[0115] As an implementation method of this embodiment, the first adjustment spacer 40 is used to adjust the distance between the connecting seat 38 and the first support seat 41 along the X-axis direction;

[0116] The second adjusting spacer 43 is used to adjust the distance between the first supporting base 41 and the second supporting base 42 along the Y-axis direction.

[0117] The third adjusting spacer 45 is used to adjust the distance between the supporting block 44 and the second supporting seat 42 along the Z-axis direction.

[0118] In this solution, position adjustment is achieved by replacing the above gaskets with different thicknesses.

[0119] As an implementation of this embodiment, each support assembly 13 has two support modules 35 , one support module 35 is used to install the first positioning pin 29 , and the other support module 35 is used to install the second positioning pin 30 .

[0120] As an implementation of this embodiment, the pressing assembly 17 includes:

[0121] The pressing cylinder module 46 is mounted on the base 11 , and a pressing arm 47 is provided on the output end of the pressing cylinder module 46 . The pressing arm 47 is provided on the output end of the pressing cylinder module 46 through a mounting arm 48 .

[0122] The pressing cylinder module 46 adopts a rotary cylinder. At this time, the mounting arm 48 can rotate, thereby driving the pressing arm 47 to press the workpiece 15 .

[0123] This solution works as follows:

[0124] The initial state of the tooling, such as Figure 1 As shown, at this time, the positioning lifting assembly 34 is in the jacking state, the first positioning pin 29 of the exit module 36 is in the extended state, the pressing arm 47 in the pressing assembly 17 is in the upright state, and the plug part 28 in the expansion assembly 16 is in the retracted state. The worker first manually places the first top plate 20 in the corresponding position of the tooling, and makes the positioning holes on the first top plate 20 penetrate the corresponding positioning pins respectively, and puts the second top plate 21 in the corresponding position of the tooling, and makes the positioning holes on the second top plate 21 penetrate the corresponding positioning pins respectively. Figure 3 As shown, after placement is completed, the bottom plate 18 is buckled in above the two top plates, and at the same time, two long first positioning pins 29 are inserted into the positioning holes on the bottom plate 18. At this time, the three components of the workpiece 15 are restricted in their degrees of freedom by two pins on one side, and the relative positions of the components of the workpiece 15 are accurate. After completing the steps of placing the components of the workpiece 15, the worker evacuates to a safe position and presses the start button. At this time, the piston rod of the first telescopic member 25 in the expansion assembly 16 is pushed out, and the block part 28 is driven by the articulated arm 26 to move laterally along the length direction of the first slide rail assembly 24 and outward. The block parts 28 on both sides are respectively inserted into the gaps between the first top plate 20, the second top plate 21 and the bottom plate 18 of the workpiece 15, and the pressing assembly 17 lowers the clamping arm 47 to make the workpiece 15 fit tightly with the block part 28. Then the automatic welding process begins.

[0125] After welding is completed, the down-pressing assembly 17 raises the clamping arm 47, the expansion assembly 16 retracts the plug portion 28, and the second telescopic member 39 in the positioning and lifting assembly 34 drives the first and second positioning pins 29, 30 to move downward synchronously, and the second positioning pin 30 disengages from the workpiece 15. The exit module 36 drives the first positioning pin 29 to retract, and the top of the first positioning pin 29 disengages from the bottom plate 18. At this time, the two first positioning pins 29 remain in the positioning holes of the first and second top plates 20, 21 of the workpiece 15, respectively, and serve to limit the workpiece 15. At this time, the plug portion 28 supports the workpiece 15. At the same time, the worker can easily remove the workpiece 15 from the tooling.

[0126] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
