Description

Technical Field

[0001] The utility model relates to the technical field of evaporator manufacturing, in particular to an evaporator welding frame. Background Art

[0002] An automotive evaporator is a main component for refrigeration in an automotive air conditioner. When the temperature inside the vehicle is relatively high, the automotive air conditioner can be started, and through the refrigeration effect of the evaporator, the purpose of reducing the temperature of the passenger compartment can be achieved, thereby improving the comfort of driving and riding.

[0003] In view of the important role of the evaporator, each produced evaporator needs to be subjected to leak detection to ensure that the sealing performance of the evaporator is qualified and to avoid leakage during the operation of the evaporator. During the brazing process of the existing evaporator core, multiple people are required to operate simultaneously. One person is responsible for welding, and the other person is responsible for supporting the inlet and outlet pipes. When welding alone, one hand needs to support the inlet and outlet pipes, and the other hand needs to perform other operations. This method cannot effectively support the inlet and outlet pipes. During the welding process, the inlet and outlet pipes will be deformed or even fall off from the evaporator core. There is a gap between the evaporator core and the inlet and outlet pipes, resulting in the detection gas leaking out from the gap during leak detection, and it cannot pass the leak detection. Extra workload is required to shape the unqualified evaporators, which affects the working efficiency during leak detection, and even the unqualified evaporators need to be scrapped.

[0004] Therefore, there is an urgent need for an evaporator welding frame to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an evaporator welding frame to solve the problems in the prior art that during the welding process of the evaporator, the inlet and outlet pipes will be deformed or the welding quality between the inlet and outlet pipes and the evaporator is poor, resulting in core leakage during detection and unable to pass the detection, and the extra workload caused by shaping the evaporator or even the waste caused by scrapping the evaporator.

[0014] Further, the support assembly includes a fixing member and a supporting member. The fixing member is arranged on the frame body, and the supporting member is rotatably arranged on the fixing member and can be switched between the avoidance position and the working position.

[0015] Further, the evaporator welding frame further includes a locking assembly, which has a locking state and an unlocking state; in the locking state, the locking assembly locks the supporting member and the fixing member; in the unlocking state, the supporting member and the fixing member are unlocked.

[0037] The evaporator welding frame provided in this embodiment can be applied to the technical field of evaporators, especially in the welding process of evaporators, to solve the technical problems in the prior art that during the welding process of the evaporator, the inlet and outlet pipe 1 will be deformed or the welding quality between the inlet and outlet pipe 1 and the evaporator is poor, resulting in poor sealing of the sealing plug during leak detection, and thus false alarms of core leakage will occur during detection, affecting the working efficiency during leak detection.

[0038] Optionally, the way of leak detection is helium detection.

[0039] Such as Figure 1As shown, the evaporator welding frame includes a frame body 3, a supporting member 4, and a support assembly. The supporting member 4 is arranged on the frame body 3, and an evaporator core mounting position is provided on the supporting member 4 for positioning the evaporator core 2. The support assembly is arranged on the frame body 3 to support the inlet and outlet pipes 1.

[0040] Specifically, as Figure 1 shown, in this embodiment, the supporting member 4 is arranged on the frame body 3. The supporting member 4 is a tray, and the middle position of the tray is recessed to form an evaporator core mounting position. The evaporator core mounting position is adapted to the size of the evaporator core 2 and is used to position the evaporator core 2. When using the evaporator welding frame to braze the evaporator, the evaporator core 2 is placed on the evaporator core mounting position on the supporting member 4 and is positioned by the evaporator core mounting position. The support assembly is arranged on the frame body 3 to support the inlet and outlet pipes 1 to ensure that the inlet and outlet pipes 1 are always supported during the brazing process. When using the evaporator welding frame, one end of the inlet and outlet pipe 1 is connected to the support assembly, and the other end is connected to the evaporator core 2. The support assembly forms a stable support for the inlet and outlet pipes 1, ensuring that the inlet and outlet pipes 1 will not deform or fall off in the high-temperature brazing furnace. By positioning the evaporator core 2 and supporting the inlet and outlet pipes 1 at the same time, the brazing position of the inlet and outlet pipes 1 is ensured to be stable and unified, improving the qualification rate of product leak detection and reducing the extra workload caused by shaping and the waste caused by scrapping.

[0041] Further, the tray is formed by assembling and fixing a plurality of vertical plates. In this embodiment, the tray is fixed by four vertical plates in a "well" shape.

[0042] Of course, in other embodiments, the supporting member 4 can also be set to other structures according to needs, as long as it can support and position the evaporator core, and no further limitations are made here.

[0043] Further, the support assembly is rotatably arranged on the frame body 3 and has an avoidance position and a working position. In the avoidance position, the support assembly rotates to the side of the supporting member 4. In the working position, the support assembly rotates above the supporting member 4 to support the inlet and outlet pipes 1.

[0044] Specifically, in this embodiment, in order to prevent the support component from interfering with the operator's placement and removal of the evaporator core 2, the support component is rotatably arranged on the frame body 3 and has an avoidance position and a working position. When it is necessary to place and remove the evaporator core 2, the support component is rotated to the avoidance position. At this time, the support component is vertically staggered with the supporting member 4 and the support component is located beside the supporting member 4 (that is, in the vertical direction projection, the projection of the support component does not fall within the projection range of the supporting member 4), which is convenient for the operator to place and remove the evaporator core 2. When brazing is required, first place the evaporator core 2 on the evaporator core installation position on the supporting member 4, and then rotate the support component to the working position. At this time, as Figure 1 shown, the support component rotates above the supporting member 4 to be able to support the liquid inlet and outlet pipe 1, ensuring that the liquid inlet and outlet pipe 1 is always supported during the brazing process.

[0045] Further, referring to Figure 2 , the support component includes a fixing member 51 and a supporting member 52. The fixing member 51 is arranged on the frame body 3, and the supporting member 52 is rotatably arranged on the fixing member 51 and can be switched between the avoidance position and the working position.

[0046] Specifically, in this embodiment, the support component includes an L-shaped supporting member 52 and a fixing member 51. The fixing member 51 is arranged on the frame body 3. For the convenience of understanding the technical solution of the present application, as Figure 2 and Figure 3 shown, a first through hole is formed in the fixing member 51. The L-shaped supporting member 52 includes a first section 521, a second section 522 and a third section 523 arranged in sequence. The cross section of the first section 521 is circular and is rotatably arranged in the first through hole. The second section 522 and the first section 521 both extend in the vertical direction and are coaxially arranged. The cross-sectional area of the second section 522 is larger than that of the first section 521, and the lower end surface of the second section 522 contacts the fixing member 51 to form a support for the supporting member 52. The third section 523 is perpendicular to the second section 522, that is, the third section 523 extends in the horizontal direction or approximately in the horizontal direction, and a supporting position for supporting the liquid inlet and outlet pipe 1 is arranged on the third section 523. The L-shaped supporting member 52 can rotate around the axis of the first through hole arranged on the fixing member 51 to switch the L-shaped supporting member 52 between the avoidance position and the working position.

[0047] Further, the evaporator welding frame further includes a locking component. The locking component is arranged on the frame body 3 and has a locked state and an unlocked state; in the locked state, the locking component locks the supporting member 52 and the fixing member 51; in the unlocked state, the supporting member 52 and the fixing member 51 are unlocked.

[0048] Specifically, in this embodiment, in order to ensure that the support assembly remains stable in the working position and does not easily rotate to cause poor brazing quality, the evaporator welding frame also includes a locking assembly. The locking assembly is arranged on the frame body 3, and the locking assembly has a locked state and an unlocked state. Figure 2 In the locked state, the locking assembly locks the support member 52 and the fixing member 51, so that the support member can be fixed in the working position, thereby ensuring that the inlet and outlet liquid pipes 1 can always be supported during the welding process. In the unlocked state, the locking assembly unlocks the support member 52 and the fixing member 51. At this time, the support member 52 can rotate relative to the fixing member 51, so that when taking and placing the evaporator core 2, the support member 52 is rotated to a position staggered above and below the supporting member 4.

[0049] Furthermore, the locking assembly includes a locking member 62, which is movably disposed on one of the supporting member 52 or the fixing member 51, and can be plugged into or separated from the other of the supporting member 52 and the fixing member 51 to switch between a locked state and an unlocked state.

[0050] Specifically, the locking assembly includes a locking member 62, which is movably disposed on the supporting member 52 and can be plugged into or separated from the fixing member 51 to switch between a locked state and an unlocked state, or the locking member 62 is movably disposed on the fixing member 51 and can be plugged into or separated from the supporting member 52 to switch between a locked state and an unlocked state.

[0051] Specifically, in this embodiment, Figures 2 to 5 As shown, the locking assembly includes a locking member 62. The locking member 62 is movably arranged in the third through hole 5231 opened on the third section 523 of the support member 52, and can be plugged into or separated from the fixing member 51. When the locking member 62 passes through the third through hole 5231 and is plugged into the fixing member 51, the locking assembly is in a locked state, and the support member 52 and the fixing member 51 cannot move relative to each other. When the locking member 62 is separated from the fixing member 51, the locking assembly is in an unlocked state, and the support member 52 can rotate around the axis of the first through hole.

[0052] Further, see Figure 2 and Figure 5 The locking member 62 is movably arranged on the supporting member 52 and can be connected to or separated from the fixing member 51. A limiting member 621 is also arranged on the locking member 62. The limiting member 621 can move with the locking member 62 to abut against the supporting member 52 to limit the locking member 62 from being separated from the supporting member 52.

[0053] Specifically, Figure 2 , Figure 3 and Figure 5As shown, in this embodiment, the limiting member 621 is a flange provided on the locking member 62. The limiting member 621 can move with the locking member 62 to abut against the third section 523 of the support member 52, preventing the locking member 62 from disengaging from the third through hole 5231 after disengaging from the second through hole, thereby avoiding the loss of the locking member 62.

[0054] Further, the locking member 62 is movably arranged on the support member 52 and can be inserted into or separated from the fixing member 51. The locking assembly further includes a guiding member 63. The guiding member 63 is arranged on the support member 52, and a locking hole 61 is arranged on the fixing member 51. The locking member 62 always passes through the guiding member 63 and can selectively pass through the locking hole 61.

[0055] Specifically, as Figure 2 and Figure 3 shown, in this embodiment, the locking assembly further includes a guiding member 63. The guiding member 63 is a fixing plate provided with a fourth through hole. The guiding member 63 is arranged on the second section 522 of the support member 52. The locking member 62 sequentially passes through the third through hole 5231, the fourth through hole and the locking hole 61.

[0056] That is, the guiding member 63 is arranged between the third through hole 5231 and the locking hole 61. The locking member 62 always passes through the guiding member 63 to guide the locking member 62 to smoothly pass through the locking hole 61. When the locking member 62 passes through the locking hole 61, the locking assembly is in a locked state; when the locking member 62 is pulled out from the locking hole 61, the locking assembly is in an unlocked state.

[0057] By providing the guiding member 63, not only can the movement direction of the locking member 62 be guided, but also the locking degree of the locking assembly can be improved, thereby improving the stability of the support assembly in the working position and avoiding deformation or detachment of the liquid inlet and outlet pipe 1 in the high-temperature brazing furnace.

[0058] Further, in order to facilitate the insertion of the locking member 62 into the locking hole 61 to make the locking assembly in a locked state, a guiding inclined surface is further provided at one end of the locking member 62 close to the locking hole 61.

[0059] Further, a handle 64 is also provided on the locking member 62.

[0060] Specifically, as Figure 2 and Figure 4 shown, in order to facilitate the operator to disengage the locking member 62 from the locking hole 61, unlock the locking assembly and switch the support assembly from the working position to the avoidance position, and further facilitate the operator to place and take the evaporator core 2, a handle 64 is also provided on the locking member 62. The operator can lift the locking member 62 by lifting the handle 64, thereby unlocking the locking assembly.

[0061] Further, the locking assembly also includes a buffer, and the buffer is arranged between the support member 52 and the handle 64. Specifically, when the support assembly is switched from the avoidance state to the working state during welding, in order to prevent the operator from inserting the locking member 62 into the lock hole 61 to switch the locking assembly to the locking state to lock the support member 52, the locking member 62 hits the support member 52 due to its own weight, causing the position of the support member 52 to change, the locking assembly also includes a buffer. The buffer is arranged between the support member 52 and the handle 64. The impact of the locking member 62's own weight on the support member 52 is reduced and alleviated by providing the buffer. In the present embodiment, the buffer is a sponge (not shown in the figure) arranged between the support member 52 and the handle 64. Of course, in other embodiments, the buffer can also be a spring, a rubber member or a silicone member, as long as it can play a buffering role, and no excessive restrictions are made here.

[0062] Furthermore, a plurality of supporting members 4 are disposed on the frame body 3 and the plurality of supporting members 4 are arranged in an array, and each supporting member 4 is correspondingly provided with at least one supporting assembly.

[0063] Specifically, Figure 5 As shown, in this embodiment, eight supporting members 4 arranged in an array are provided on the frame body 3, and each supporting member 4 is correspondingly provided with a supporting assembly, so that the evaporator welding frame of the present application can simultaneously provide support for the eight inlet and outlet liquid pipes 1 when they are welded to the corresponding evaporator core 2, thereby greatly improving the work efficiency.

[0064] Of course, in other embodiments, the number of supporting members 4 may also be set to other numbers as required, and no further restrictions are imposed herein.

[0065] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
