DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] according to Figure 1-3 The utility model provides a quick-changing device for welding fixtures, including: a pushing platform 1, a processing platform 2, and a transport platform 3; the pushing platform 1 is connected to the processing platform 2; one end of the transport platform 3 is connected to the pushing platform 1, and the other end is connected to the processing platform 2.

[0018] When the clamp is needed, place the clamp on the transport platform 3, start the transport platform 3, so that the clamp is transported to the pushing platform 1, start the pushing platform 1, so that the clamp is pushed to the processing platform 2 for fixation, and then it can be used. If multiple clamps are used, multiple clamps can be placed together on the transport platform 3. When a clamp is on the processing platform 2 and the clamp needs to be replaced, start the transport platform 3, so that the clamp is transported to the pushing platform 1, start the pushing platform 1, so that the latter clamp pushes the former clamp, so that the former furniture is pushed out of the processing platform 2 to the transport platform 3, and the latter clamp is transported to the processing platform 2. Repeat this operation according to the clamp to be used, and the corresponding clamp can be sent to the processing platform 2, and the replacement is quick.

[0019] The transport platform 3 includes: a conveyor belt 31 and a guardrail 32; one end of the conveyor belt is connected to the push platform 1, and the other end is connected to the processing platform 2; the guardrail 32 is arranged on both sides of the conveyor belt 31. The push platform 1 includes: a push plate 11 and a push cylinder 12; the push plate 11 is arranged on the side of the push platform 1 away from the processing platform 2; the push cylinder 12 is connected to the push plate 11, so that the push plate 11 can move relative to the processing platform 2. The processing platform 2 includes: a clamping plate 21, a clamping cylinder 22, and a fixed platform 26; the clamping plate 21 is arranged on one side of the processing platform 2, and the fixed plate 26 is arranged on the other side of the processing platform 2; the clamping plate 21 is connected to the clamping cylinder 22.

[0020] The fixture is transported on the transport platform 3 by a conveyor belt 31, and a guardrail 32 is provided to prevent the fixture from falling. When the fixture is transported to the pushing platform 1, the pushing cylinder 12 is started so that the pushing plate 11 pushes the fixture to the processing platform 2, and then the clamping cylinder 22 is started to fix it by the clamping plate 21.

[0021] The processing table 2 further includes: a telescopic plate 23, a telescopic rod 24; the telescopic rod 24 includes: a fixed cylinder 241, a movable rod 242; the telescopic rod 24 is connected to the clamping plate 21; the telescopic rod 24 is connected to the fixed plate 26; a spring 2411 is fixedly arranged in the fixed cylinder 241; the telescopic rod 24 is connected to the spring 2411; the movable rod 242 can be telescoped in the fixed cylinder 241; the telescopic plate 23 is connected to the side of the telescopic rod 24 away from the clamping plate 21. The diameter of the telescopic plate 23 is larger than the diameter of the telescopic rod 24.

[0022] After the clamp is pushed onto the processing table 2, the clamp needs to be fixed. The chassis of many clamps are round or uneven. When using a flat plate for clamping, the force-bearing area of ​​many clamps is only the part that is more convex, which will cause excessive local force and easily cause damage to the clamp. The utility model is provided with a telescopic rod 24 and a telescopic plate 23 on the clamping plate 21 and the fixed plate 26. When the clamp needs to be clamped, the clamping cylinder 22 is started, and the clamping plate 21 moves toward the fixed plate 26, so that the telescopic plate 23 contacts the clamp and pushes the clamp to move toward the fixed plate 26, and finally the clamp is clamped by the clamping plate 21 and the fixed plate 26. At this time, the convex part and the concave part of the clamp are clamped by the telescopic plate 23 respectively, wherein the force applied by the telescopic plate 23 in the concave part is small, but the pressure on the convex part is shared to a certain extent. The diameter of the telescopic plate 23 is larger than the diameter of the telescopic rod 24 to increase the force-bearing area of ​​the clamp and avoid excessive concentration of pressure. By using the fixed tube 241 and the movable rod 242 in conjunction with the spring connection, compared to using the spring 2411 alone to connect the telescopic plate 23 and the clamping plate 21 and the fixed plate 26, the telescopic plate 23 can be prevented from causing the spring to sag, causing the telescopic plate to tilt and resulting in the telescopic plate 23 being unable to clamp the clamp well.

[0023] The processing table 2 also includes: a baffle 25; the baffle 25 is arranged on the side of the fixed plate 26 away from the pushing table 1; the baffle 25 includes: a rotating rod 251, a limiting plate 252, and a rotating motor 253; the rotating rod 251 is connected to the rotating motor 253; the limiting plate 252 is connected to the rotating rod 251.

[0024] When the rear clamp is pushed onto the workbench 2, the front clamp will be pushed. When the front clamp is pushed onto the transport platform 3, it will be driven away from the workbench 2 by the conveyor belt 31. At this time, the motor 253 is started to rotate the rotating rod 251, driving the limit plate 252 to rotate, so that the limit plate 252 rotates to be in contact with the surface of the processing table 2, and the baffle 25 is used to limit the rear clamp when it is pushed, so as to prevent the rear clamp from being pushed out of the workbench 2.

[0025] The use principle and workflow of this utility model:

[0026] When the utility model is in use, first place the clamp to be used on the transport platform 3, then start the conveyor belt 31, so that the clamp is transported to the pushing platform 1 on the conveyor belt 31, and when a clamp is transported to the pushing platform 1, start the pushing cylinder 12, so that the pushing plate 11 moves toward the clamp, and pushes the clamp to move toward the workbench 2, and at the same time start the rotating cylinder 253, so that the rotating rod 251 rotates, driving the limit plate 252 to rotate until it is in contact with the surface of the workbench 2, and when the clamp is pushed to conflict with the limit plate 252, stop pushing, and then start the clamping cylinder 22, drive the clamping plate 21 to move toward the clamp, so that the telescopic plate 23 pushes the clamp to conflict with the telescopic plate 23 on the fixed plate 26, and during the conflict, the telescopic plate 23 drives the movable rod 242 to move into the fixed cylinder 241, so that the spring 2411 is compressed, and finally the clamp is clamped. When the fixture needs to be replaced, start the clamping cylinder 22 to move the clamping plate 21 away from the fixture so that the fixture is released, and at the same time start the rotating cylinder 253 to move the limiting plate 252 away from the table surface of the workbench 2, and then start the conveyor belt 31 to transport the next fixture to the pushing table 1, start the pushing cylinder 12 to drive the next fixture to move toward the workbench 2 and conflict with the previous fixture, so that the previous fixture is away from the workbench 2 and moves toward the transport table 3. When the previous fixture contacts the conveyor belt 31, it is driven by the conveyor belt to leave the workbench 2, and the next fixture is driven onto the workbench. According to this method, the fixtures on the transport table 3 can be moved to the workbench 2 in sequence. After determining the fixture to be used, the limiting and clamping can be performed according to the above content.

[0027] In summary, the utility model connects the pushing table and the workbench, and connects the transport table to the two, so that the fixture can be transported back and forth between the three, and can be quickly fixed and removed through the workbench and the pushing table, which reduces manpower pulling, speeds up the replacement of workpieces, and makes the processing efficiency higher.
