Description

Technical Field

[0001] This application relates to the technical field of welding and fixing, and more specifically, to a welding auxiliary device. Background Technology

[0002] Cooling chambers in precision semiconductor instruments are used to store circulating cooling media. The welding process for these cooling chambers requires a high degree of airtightness. Currently, the welding method for cooling chambers involves manually welding the chamber directly onto a workbench.

[0003] The inventors of this application discovered that the welding method for the aforementioned cooling box does not clamp and fix the weld lines on both sides, and that the high welding temperature causes deformation of the weld line area. Furthermore, the welding method requires repeated manual adjustments to the angle and position of the cooling box, resulting in long welding times and low welding efficiency.

The described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] According to one aspect of this application, a welding auxiliary device is provided. Figure 1 A schematic diagram of the welding auxiliary device according to an embodiment of this application is shown.

[0033] For example, welding aid 1 is used to fix the object to be welded (not shown in the figure). The object to be welded can be a cooling box.

[0034] For example, the cooling tank is a water tank. The technical solution of this application will be described below using a water tank.

[0035] According to the example embodiment, such as Figure 1As shown, the welding auxiliary device 1 includes a base 11, a support assembly 12, a support and limiting plate 13, and a clamping assembly 14.

[0036] For example, the weld lines of the water tank can be pre-spot welded and fixed. For example, the base 11 can be a metal plate with high stability. The support component 12 can be a metal support component that provides support force. The support and limiting plate 13 can be a metal plate that provides support force and limiting function to the water tank. The clamping component 14 can be a component that clamps and fixes the water tank.

[0037] For example, the base 11 can be rectangular, and can be set according to user needs, without limitation here.

[0038] A support assembly 12 is disposed on a base 11. A supporting and limiting plate 13 is disposed on the support assembly 12 for supporting and limiting the water tank. A clamping assembly 14 is disposed on the base 11. The clamping assembly 14 includes at least a first clamping member 141 and a second clamping member 142, which are disposed opposite to each other on both sides of the supporting and limiting plate 13. The first clamping member 141 includes a first driving member 1411 and a first clamping plate assembly 1412. The first driving member 1411 is disposed on the base 11 and located on one side of the support assembly 12. One end of the first clamping plate assembly 1412 is disposed on the first driving member 1411, and the other end is disposed above the supporting and limiting plate 13 for clamping one side of the water tank. The second clamping member 142 includes a second driving member 1421 and a second clamping plate assembly 1422. The second driving member 1421 is disposed on the base 11 and located on the other side of the support assembly 12. One end of the second clamping plate assembly 1422 is disposed on the second driving member 1421, and the other end is disposed above the supporting limiting plate 13, for clamping the other side of the water tank.

[0039] For example, the connection between the support component 12 and the base 11 can be a fixed connection or a detachable connection.

[0040] For example, the fixed connection method can be welding. The detachable connection method can be threaded connection or snap-fit ​​connection.

[0041] For example, the connection between the clamping assembly 14 and the base 11 can be a detachable connection.

[0042] For example, the clamping assembly 14 can be detachably connected to the base 11 by means of a screw engaging with a threaded hole (not shown) provided in the base.

[0043] For example, the clamping assembly 14 may include at least one set of first clamping members 141 and second clamping members 142.

[0044] For example, the first drive member 1411 can be a displacement adjustment device with telescopic function. The first clamping plate assembly 1412 can be a clamping component that can clamp the water tank from one side.

[0045] For example, the first driving member 1411 may be an electric cylinder or a pneumatic cylinder with a driving function, which can drive the opening and closing of the first clamping member assembly 1412 to clamp or release the water tank.

[0046] For example, the second drive member 1421 can be a displacement adjustment device with telescopic function. The second clamping plate assembly 1422 can be a clamping component that can clamp the water tank from the other side.

[0047] For example, the second drive member 1421 may be an electric cylinder or a pneumatic cylinder with a driving function, which can drive the opening and closing of the second clamping plate assembly 1422 to clamp or release the water tank.

[0048] For example, the first drive member 1411 and the second drive member 1421 are both cylinders, or the first drive member 1411 and the second drive member 1421 are both electric cylinders.

[0049] The first driving member 1411 controls the opening and closing state of the first clamping plate assembly 1412 according to the first control command sent by the external control mechanism (not shown in the figure), and the second driving member 1421 controls the opening and closing state of the second clamping plate assembly 1422 according to the second control command sent by the external control mechanism, so that the first clamping plate assembly 1412 and the second clamping plate assembly 1422 clamp the water tank from both sides.

[0050] For example, the external control mechanism is a control device that can issue control commands. Both the first control command and the second control command can be commands that control the first drive member 1411 and the second drive member 1421 to generate a driving action, so as to drive the opening and closing of the first clamping plate assembly 1412 and the second clamping plate assembly 1422.

[0051] Through the above embodiments, this application initially limits and fixes the water tank by supporting and limiting the plate. By driving the opening and closing states of the first clamping plate assembly and the second clamping plate assembly, clamping forces are generated on opposite sides of the water tank, thereby reducing the amount of welding deformation during the water tank welding process under the action of the clamping force. In addition, the process of clamping the water tank in this application has fewer steps and shorter time, thereby improving welding efficiency.

[0052] Figure 2 A schematic diagram of the structure of the support component according to an embodiment of this application is shown.

[0053] According to the example embodiment, such as Figure 1 and Figure 2As shown, the support assembly 12 includes a first vertical plate 121, a second vertical plate 122, and at least one first horizontal plate 123. The first vertical plate 121 is disposed on one side of the base 11. The second vertical plate 122 is disposed opposite to the first vertical plate 121 on the other side of the base 11. One end of the at least one first horizontal plate 123 is connected to the first vertical plate 121, and the other end is connected to the second vertical plate 122.

[0054] For example, the first vertical plate 121 and the second vertical plate 122 can be rectangular metal plates. The first vertical plate 121 and the second vertical plate 122 can be arranged parallel to each other. The first horizontal plate 123 can be a rectangular metal plate, and the connection method with the first vertical plate 121 and the second vertical plate 122 can be a fixed connection method or a detachable connection method.

[0055] For example, the fixed connection method can be welding. The detachable connection method can be threaded connection or snap-fit ​​connection.

[0056] Through the above embodiments, this application improves the support force and support stability by setting a first vertical plate, a second vertical plate and at least one first horizontal plate to form an I-shaped support structure, thereby improving the support strength.

[0057] Figure 3 A schematic diagram of the supporting and limiting plate according to an embodiment of this application is shown.

[0058] According to the example embodiment, such as Figure 3 As shown, the supporting limiting plate 13 includes two limiting bosses 131 and at least two limiting members 132. The two limiting bosses 131 are disposed opposite to each other at both ends of the supporting limiting plate 13 and are used to limit the water tank. The at least two limiting members 132 are disposed adjacent to the limiting bosses 131 and are used to cooperate with the limiting bosses 131 to limit the water tank.

[0059] For example, the limiting component 132 can be a positioning pin.

[0060] For example, the locating pin can be a circular or diamond-shaped locating pin. The locating pin can cooperate with the limiting boss 131 to limit the water tank from all sides.

[0061] Through the above embodiments, this application provides a limiting function by setting a boss and a limiting member, thereby achieving the initial limiting and fixing of the water tank.

[0062] According to the example embodiment, such as Figure 3 As shown, the supporting and limiting plate 13 also includes a reinforcing rib receiving groove 133. The reinforcing rib receiving groove 133 is used to receive the reinforcing ribs at the bottom of the water tank to limit the water tank.

[0063] Through the above embodiments, this application further limits and fixes the water tank by setting a reinforcing rib receiving groove, thereby further improving the stability of the water tank on the supporting limiting plate.

[0064] According to the example embodiment, such as Figure 3 As shown, the supporting limiting plate 13 also includes at least two clamping plate assembly limiting grooves 135. The at least two clamping plate assembly limiting grooves 135 are disposed opposite to each other on both sides of the supporting limiting plate 13, and are used to limit the first clamping plate assembly 1412 and the second clamping plate assembly 1422.

[0065] Through the above embodiments, this application sets a clamping plate assembly limiting groove to limit and fix the clamping plate assembly, thereby avoiding the offset of the clamping plate assembly during the opening and closing process and ensuring the smoothness of the opening and closing of the clamping plate assembly.

[0066] Figure 4 A schematic diagram of the structure of the first clamping plate assembly according to an embodiment of this application is shown.

[0067] According to the example embodiment, such as Figure 4 As shown, the first clamping plate assembly 1412 includes a first clamping plate 14121 and a first connecting member 14122. One end of the first clamping plate 14121 is shaft-connected to the first driving end of the first driving member 1411. The first clamping plate 14121 is provided with a first connecting shaft 141211. One end of the first connecting member 14122 is connected to the first fixed end of the first driving member 1411, and the other end is connected to the first connecting shaft 141211.

[0068] Through the above embodiments, this application realizes the opening and closing of the first clamping plate assembly by means of shaft connection.

[0069] According to the example embodiment, such as Figure 1 As shown, the second clamping plate assembly 1422 includes a second clamping plate 14221 and a second connecting member 14222. One end of the second clamping plate 14221 is shaft-connected to the second driving end of the second driving member. The second clamping plate 14221 is provided with a second connecting shaft 142211. One end of the second connecting member 14222 is connected to the second fixed end of the second driving member 1421, and the other end is connected to the second connecting shaft 142211.

[0070] Through the above embodiments, this application realizes the opening and closing of the second clamping plate assembly by means of shaft connection.

[0071] According to the example embodiment, such as Figure 1 As shown, the clamping assembly 14 also includes a reversing valve 143. The reversing valve 143 is disposed on the base 11 and is used to control the driving direction of the first driving member 1411 and the second driving member 1421, so as to control the opening and closing state of the first clamping plate assembly 1412 and the second clamping plate assembly 1422, so that the first clamping plate assembly 1412 and the second clamping plate assembly 1422 clamp the water tank from both sides.

[0072] For example, when both the first clamping plate assembly 1412 and the second clamping plate assembly 1422 are in the open state, the water tank is released. When both the first clamping plate assembly 1412 and the second clamping plate assembly 1422 are in the closed state, the water tank is clamped.

[0073] Through the above embodiments, this application changes the driving direction of the first driving member and the second driving member by setting a reversing valve, thereby changing the opening and closing state of the first clamping plate assembly and the second clamping plate assembly, and thus realizing the clamping or releasing of the water tank.

[0074] Figure 5 A schematic diagram of the base structure according to an embodiment of this application is shown.

[0075] According to the example embodiment, such as Figure 2 , Figure 3 and Figure 5 As shown, the base 11 is provided with a first weight-reducing hole 111. The support component 12 is provided with a second weight-reducing hole 124. The supporting and limiting plate 13 is provided with a third weight-reducing hole 134.

[0076] For example, the shapes of the first weight-reducing hole 111, the second weight-reducing hole 124 and the third weight-reducing hole 134 can be freely set by the user and are not limited here.

[0077] For example, the first weight-reducing hole 111, the second weight-reducing hole 124 and the third weight-reducing hole 134 can be rectangular or circular in shape.

[0078] Through the above embodiments, this application reduces the weight of the welding auxiliary device by setting the first weight reduction hole, the second weight reduction hole and the third weight reduction hole, thereby reducing the consumables of the welding auxiliary device and thus reducing the production cost of the welding auxiliary device.
