Description

Technical Field

[0001] This utility model relates to the field of welding processing technology, specifically to a reverse-pushing material-retrieving welding fixture. Background Technology

[0002] Currently, welding fixtures typically involve placing the workpiece to be welded on a platform, clamping it with fixtures, and then performing the welding operation. Because the workpiece heats up significantly during welding, even after welding, some heat remains on its surface. To remove the welded workpiece, workers must wear heat-resistant gloves or use tools (such as pliers). Furthermore, during removal, the workpiece may become tightly pressed against the platform due to the downward pressure exerted by the fixtures or the workpiece being large and planar. In such cases, workers must manually release the workpiece from the platform before removing it, increasing the time required for removal and reducing production efficiency.

[0003] To address the shortcomings of the aforementioned material handling methods, even though existing technologies have improved material handling by adding robotic arms to achieve automated material handling, the high cost of using robotic arms prevents their large-scale application. Furthermore, the high complexity of robotic arms and their associated electrical equipment results in their large size, making them unsuitable for use on small welding fixtures and further narrowing their application scope.

[0004] To address these technical problems, we propose a reverse-pull material-retrieving welding fixture. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a reverse-push material-retrieving welding fixture. After the workpiece is welded on the platform, the pusher can push the workpiece away from the platform, allowing the worker to directly pick up the workpiece.

[0006] To solve the above problems, this utility model provides the following technical solution:

[0007] A reverse-push material-retrieving welding fixture includes a loading platform whose top surface forms a bearing surface, a clamp located beside the loading platform, and a pusher located below the loading platform. The pusher includes a drive source located below the loading platform, and a pusher pin is provided on the execution end of the drive source. A through hole is provided on the loading platform for the pusher pin to pass through from bottom to top, and the through hole is located within the working area of ​​the bearing surface.

[0008] As a further embodiment of this utility model: the execution end of the drive source is fixedly provided with an adapter plate, and multiple push pins are fixedly provided on the adapter plate. Multiple through holes are correspondingly opened in the area of ​​the bearing surface on the loading platform, so as to correspond one-to-one with the multiple push pins.

[0009] As a further embodiment of this utility model: the clamp includes a support frame and a power source both disposed on the side of the loading platform. A pressure plate for pressing the workpiece is hinged on the support frame. The actuating end of the power source is used to apply downward pressure to the pressure plate. The multiple through holes are all located within the area of ​​the pressure plate.

[0010] As a further embodiment of this utility model: the power source includes a tilting cylinder, and the piston end of the tilting cylinder is provided with a pressure claw, which can move toward or away from the bearing surface.

[0011] As a further embodiment of this utility model: the support frame and the power source are respectively arranged on opposite sides of the loading platform.

[0012] As a further embodiment of this utility model, a positioning pin is provided on the bearing surface of the loading platform.

[0013] As a further embodiment of this utility model, a positioning block is provided on the bearing surface of the loading platform.

[0014] As a further embodiment of this utility model, the welding fixture also includes a base plate for mounting the loading platform, clamps, and pushers.

[0015] As a further embodiment of this utility model, the pressure plate is provided with slots for exposing the welding position of the workpiece.

[0016] As a further embodiment of this invention, the driving source is a direct-push cylinder.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. With the pusher set, after the workpiece is welded on the bearing surface, the workpiece and the bearing surface are in a tight fit. At this time, the pusher pin on the pusher can push the workpiece from bottom to top until the fit between the workpiece and the bearing surface is released, which makes it easy for the staff to directly pick up the material. The operation is simple.

[0019] 2. Through the setting of the adapter plate and multiple push pins, during the push, the workpiece is pushed by multiple push pins from bottom to top. The push is distributed in a planar manner, so the push applied to the workpiece is a uniform planar force, ensuring that the workpiece will not be damaged during the push process.

[0020] 3. By setting up the fixture, the support frame and power source in the fixture are respectively set on opposite sides of the loading platform, which can effectively reduce the space volume of the tooling;

[0021] 4. The pressure plate is equipped with slots for exposing the welding position of the workpiece, which facilitates the welding process. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] like Figures 1-3 As shown, a reverse-push material-retrieving welding fixture includes a base plate 12, a loading platform 1 on the base plate 12, a clamp on the base plate 12 located beside the loading platform 1, a pusher on the base plate 12 located below the loading platform 1, the top surface of the loading platform 1 forming a bearing surface, and a positioning block 11 and a positioning pin 10 adapted to the shape of the workpiece are provided on the bearing surface. Figure 1 and Figure 2This indicates that the platform 1, the fixture, and the pusher are set up as two sets. In use, the workpiece is accurately placed at the corresponding position on the bearing surface by the positioning pin 10 and the positioning block 11. Then, the fixture is used to clamp the workpiece, and then the welding process is carried out. After the welding is completed, the fixture is reset, and the pusher is used to push the workpiece upward, so that the workpiece is away from the bearing surface, that is, the workpiece is released from the contact state with the bearing surface. Then, the operator can directly perform the workpiece removal operation.

[0029] This application, through the setting of the pusher, can apply a pushing force to the workpiece after welding, thereby releasing the workpiece from the contact state with the bearing surface, making it convenient for subsequent workers to directly wear heat-resistant gloves or use pliers to pick up the material, making the operation convenient.

[0030] like Figure 3 As shown, the aforementioned pusher assembly includes a drive source 2 (e.g., a direct-push cylinder or an electric telescopic rod) located below the platform 1. A pusher pin 3 is mounted on the actuating end of the drive source 2. The platform 1 has a through hole 4 through which the pusher pin 3 passes from bottom to top, and the through hole 4 is located within the bearing surface area. During normal welding, the pusher pin 3 is located below the platform 1. After welding, the clamp is reset, and the drive source 2 drives the pusher pin 3 to move from bottom to top until the pusher pin 3 passes through the through hole 4, pushing the workpiece upwards. This pushing action allows the workpiece to be in a free state, making it easy for workers to handle.

[0031] In order to apply a uniform pushing force to the workpiece on the bearing surface and prevent the workpiece from being deformed and damaged, this application has a fixed adapter plate 5 at the execution end of the drive source 2, and multiple push pins 3 are fixedly installed on the adapter plate 5. Multiple through holes 4 are correspondingly opened in the area of ​​the bearing surface on the loading platform 1. That is, by using the one-to-one correspondence between the multiple push pins 3 and the multiple through holes 4, the workpiece is subjected to the pushing force of the multiple push pins 3 from bottom to top. The pushing force is distributed in a planar manner, so the pushing force applied to the workpiece is a uniform planar force, ensuring that the workpiece is not damaged during the pushing process.

[0032] Regarding the fixture configuration described above, the fixture can be any adaptable technical means found in the prior art. For example, the fixture includes a support frame 6 and a power source both located beside the loading platform 1. The support frame 6 and the power source are respectively located on opposite sides of the loading platform 1. A pressure plate 7 for pressing the workpiece is hinged to the support frame 6. The size of the pressure plate 7 is adapted to the size of the workpiece to perform surface pressing on the workpiece. At the same time, the pressure plate 7 has slots 13 for exposing the welding position of the workpiece. The side of the pressure plate 7 near the workpiece can be set as a soft contact surface (such as a contact surface made of copper material) to avoid damaging the workpiece. The power source includes a tilting cylinder 8, and the piston end of the tilting cylinder 8 is provided with a pressure claw 9. The pressure claw 9 can move towards or away from the bearing surface to achieve the pressing effect on the pressure plate 7, ensuring that the pressure plate 7 can effectively press the workpiece.

[0033] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
