Description

Technical Field

[0001] This application relates to the technical field of condenser processing, and in particular, to a pressure test tooling for a shell-less condenser. Background Art

[0002] The function of a condenser is to dissipate the heat of the high-temperature and high-pressure refrigerant gas discharged by the compressor into the air through condensation, so as to condense the high-temperature and high-pressure refrigerant gas into a high-pressure liquid at a relatively high temperature. When assembling the core of the condenser, two processes of pressing in and tying wire are required. Among them, pressing in is to insert the porous flat tube into the header to the required size; tying wire is to tie the condenser core with wire to prevent the heat sink from falling off and to make the heat sink and the porous flat tube in close contact for furnace welding.

[0003] However, in actual applications, the traditional manual assembly method is generally used to press the core pipe fittings into the shell-and-tube condenser. First, the condenser shell is horizontally installed on the workbench, and then the core pipe fittings are manually moved and pressed into the shell. Since it is difficult to keep the center line of the core pipe fittings flush with the shell during installation, the pipe fittings at the end of the core are prone to friction with the inner wall of the shell during the pressing process, damaging the oxide layer. During later use, the damaged parts are prone to rust.

[0004] Therefore, those skilled in the art have provided a pressure test tooling for a shell-less condenser to solve the problems raised in the above background art. Utility Model Content

[0005] To solve the problems raised in the above background art, this application provides a pressure test tooling for a shell-less condenser.

[0006] The pressure test tooling for a shell-less condenser provided by this application adopts the following technical solutions:

[0007] A pressure test tooling for a shell-less condenser includes a bottom plate and a top plate. A supporting channel steel is arranged between the bottom plate and the top plate. It is characterized in that a moving groove is arranged between the top plates, and a clamping arm for restricting the core pipe fittings is slidably installed in the moving groove. A pressing mechanism is arranged above the clamping arm. An adjusting track is installed on the channel steel, and a fixing mechanism for clamping the shell is slidably installed in the adjusting track. The fixing mechanism includes a moving frame and two triangular clamping blocks symmetrically arranged in the moving frame.

[0008] Preferably, two hydraulic push rods are further installed on the top plate. The output ends of the hydraulic push rods are fixedly connected to the corresponding clamping arms. The inner sides of the clamping arms are arc-shaped, and a plurality of embedded grooves are opened on the inner side edges of the arc-shaped clamping arms. Extrusion rollers are installed in the embedded grooves.

[0009] Preferably, the pressing mechanism includes a pressing table disposed above the top plate. Hydraulic control rods are installed on the bottoms at both ends of the pressing table, and support plates are also installed on both sides of the top plate. The bases of the hydraulic control rods are fixedly installed on the support plates.

[0010] Preferably, short support frames and long support frames are respectively hinged on the triangular clamping blocks. The end of the short support frame extends into the moving frame and is provided with an adjusting block, and the end of the long support frame extends into the moving frame and is provided with a fixing block. A same bolt rod is commonly provided through the adjusting block and the end of the moving frame, and a threaded fit is maintained between the adjusting block and the bolt rod.

[0011] Preferably, the fixing mechanism further includes a pushing lead screw rotatably installed in the adjusting track, and the moving frame is threadedly fitted on the pushing lead screw.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] 1. The present application is provided with clamping arms on the top plate, and extrusion rollers for cooperating with and fixing the core are installed in the clamping arms. When the two clamping arms approach each other, the core can be restricted to be stable through the extrusion rollers. Then, the pressing mechanism can be started. By lowering the pressing table, the core can be extruded into the tube shell to complete the installation, which is relatively convenient. Moreover, the core can be vertically pressed into the tube shell, thereby avoiding friction between the pipe fittings in the core and the inner wall of the tube shell, which is relatively safe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1

[0021] As Figure 1 shown, the present application discloses a pressure test tooling for a shell-less condenser, including a bottom plate 1 and a top plate 3. A supporting channel steel 2 is arranged between the bottom plate 1 and the top plate 3. A moving groove is arranged between the top plates 3, and a clamping arm 31 for restricting the core pipe fittings is slidably installed in the moving groove. Two hydraulic push rods 32 are further installed on the top plate 3, and the output ends of the hydraulic push rods 32 are fixedly connected to the corresponding clamping arms 31. The inner side of the clamping arm 31 is arc-shaped, and a plurality of embedded grooves are formed on the inner side edge of the arc of the clamping arm 31. Extrusion rollers 33 are installed in the embedded grooves, and a pressing-in mechanism is arranged above the clamping arm 31.

[0022] Specifically, two clamping arms 31 are arranged in the moving groove between the top plates 3, and a plurality of extrusion rollers 33 are arranged on the inner side of the clamping arm 31. After starting the hydraulic push rod 32, the two clamping arms 31 can be pushed to approach each other to restrict the core body and keep the core body vertical. The pressing-in mechanism further includes a pressing-in table 36 arranged above the top plate 3. Hydraulic control rods 35 are installed at the bottoms of both ends of the pressing-in table 36. Support plates 34 are also installed on both sides of the top plate 3. The bases of the hydraulic control rods 35 are fixedly installed on the support plates 34. With the cooperation of the hydraulic control rods 35, the pressing-in table 36 can be pushed to slide downward, so as to squeeze the core body downward, ensure that the core body is pressed into the tube shell for installation, and since both the core body and the tube shell are arranged vertically, the core body and the tube shell can be kept parallel, and friction between the pipe fittings in the core body and the inner wall of the tube shell can be avoided during the pressing-in process.

[0023] As Figure 2 、 Figure 3 shown, an adjustment track 4 is installed on the channel steel 2, and a fixing mechanism for clamping the tube shell is slidably installed in the adjustment track 4. The fixing mechanism includes a moving frame 41 and two triangular clamping blocks 43 symmetrically arranged in the moving frame 41. A short support frame 44 and a long support frame 45 are respectively hinged on the triangular clamping blocks 43. The end of the short support frame 44 extends into the moving frame 41 and is installed with an adjustment block 46. The end of the long support frame 45 extends into the moving frame 41 and is installed with a fixing block 47. And a same bolt rod 48 is commonly arranged through the adjustment block 46 and the end of the moving frame 41. A threaded fit is maintained between the adjustment block 46 and the bolt rod 48.

[0024] Specifically, in order to fix the shell, an adjustment track 4 is also installed on the channel steel 2, and a fixing mechanism is arranged in the adjustment track 4. During use, the adjusting block 46 can be pushed to slide in the moving frame 41 by rotating the bolt rod 48. Since the end of the long support frame 45 is installed inside the moving frame 41 through the fixing block 47, when the adjusting block 46 slides, the triangular clamping block 43 can be pushed to extend outwards through the cooperation of the short support frame 44 and the long support frame 45. Through the clamping cooperation of the four triangular clamping blocks 43, the shell can be fixed.

[0025] Furthermore, the fixing mechanism further includes a driving lead screw 42 rotatably installed in the adjustment track 4, and the moving frame 41 is installed on the driving lead screw 42 in a threaded fit. In order to facilitate the disassembly and assembly of the shell and keep the shell directly below the core, when the driving lead screw 42 rotates, it can also push the moving frame 41 to slide in the adjustment track 4, so that the fixed shell can be moved directly below the core, facilitating the pressing of the core into the shell, with simple and convenient operation.

[0026] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0027] At the same time, the content not described in detail in this specification belongs to the well-known prior art of those skilled in the art.

[0028] The implementation principle of a shell-less condenser pressure test tooling in an embodiment of the present application is as follows:

[0029] During use, first, the driving lead screw 42 is used to cooperate to push the moving frame 41 to slide in the adjustment track 4, and the moving frame 41 is slid to the end position of the adjustment track 4 to facilitate placing the shell in the moving frame 41. Then, the bolt rod 48 can be rotated in sequence. Through the cooperation of the bolt rod 48 and the adjusting block 46, the adjusting block 46 can be pushed to slide in the moving frame 41. When the adjusting block 46 slides, the triangular clamping block 43 can be pushed to extend outwards through the cooperation of the short support frame 44 and the long support frame 45, so that the triangular clamping block 43 contacts the surface of the shell. With the cooperation of the four triangular clamping blocks 43, the shell can be fixed. Then, the driving lead screw 42 can be continuously adjusted to adjust the position of the moving frame 41, and the shell is pushed directly below the core, facilitating the pressing of the core into the shell, with simple and convenient operation;

[0030] Meanwhile, when placing the core body in the top plate 3, the hydraulic push rod 32 can be activated to push the clamping arms 31 to slide. When the two clamping arms 31 approach each other, the core body can be restricted. In addition, since the inner sides of the clamping arms 31 are provided with extrusion rollers 33, while keeping the core body clamped, the extrusion rollers 33 can rotate to push the core body downward into the shell. In order to be able to press the core body into the shell, a hydraulic control rod 35 is also installed on the support plate 34. By means of the hydraulic control rod 35, the pressing platform 36 can be pulled to slide downward to press the core body into the shell, completing the installation, which is relatively convenient. Moreover, the core body can be vertically pressed into the shell, thus avoiding friction between the pipe fittings in the core body and the inner wall of the shell, which is relatively safe.
