Description

Technical Field

[0001] This utility model relates to the field of air conditioning manifold processing technology, and in particular to a tooling for pre-welding end treatment of air conditioning manifolds. Background Technology

[0002] The main function of the air conditioner's manifold is to collect all the gas inside the evaporator and then connect it to the outdoor unit, thus creating a circulation system. The air conditioner manifold typically includes a main manifold and several branch manifolds. These branch manifolds usually have the same structure and are all connected to the main manifold.

[0003] Before welding the main air collecting pipe and several branch air collecting pipes, the connection holes of the main air collecting pipe usually need to be deburred. The conventional method is to use a handheld deburring machine and the air collecting pipe to perform the deburring, which is not only time-consuming and laborious, but also prone to uneven deburring at the connection holes, resulting in unsatisfactory deburring effect and affecting subsequent welding processes. Utility Model Content

[0004] The purpose of this invention is to address the deficiencies of the existing technology by providing a tooling for pre-welding the port of an air conditioning manifold, thereby solving the problems mentioned in the background section.

[0005] A pre-welding end treatment fixture for air conditioning manifolds includes a workbench and a positioning mechanism and an end treatment mechanism mounted on the workbench. The positioning mechanism includes a first limiting seat, a second limiting seat, an electric cylinder, a pneumatic cylinder, a limiting part, and a straightening component. The first limiting seat is fixed on the workbench, and the second limiting seat slides along a track groove. The electric cylinder is mounted on the bottom of the workbench, and its output end is fixedly connected to the bottom of the second limiting seat through a connecting plate that passes through the slide groove. There are two sets of pneumatic cylinders, which are respectively mounted at one end of the first and second limiting seats. The limiting part is mounted at the output end of the pneumatic cylinder. There are two sets of straightening components, which are respectively slidably mounted on the first and second limiting seats.

[0006] The correction assembly includes a slide, an adjustment part, a first limiting end, a spring, and a second limiting end. The adjustment part is slidably disposed in the middle of the slide. The first limiting end is installed at the bottom of the adjustment part. The second limiting end is elastically installed on the slide by the spring. One end of the second limiting end can be inserted into the through hole at the adjustment part.

[0007] By adopting the above technical solution

[0008] The port processing mechanism includes a first motor, a first lead screw, a guide rail, a movable seat, a second motor, a second lead screw, a movable plate, and a deburring machine. The first lead screw is installed at the output end of the first motor. The movable seat is drivenly connected to the first lead screw and moves laterally along the guide rail. The second motor is installed on the movable seat. The second lead screw is installed at the output end of the second motor. The movable plate is drivenly connected to the second lead screw and slides along the movable seat. The deburring machine is installed on the movable plate.

[0009] The above technical solution facilitates the deburring of the air conditioning manifold connection hole.

[0010] Both the first limiting seat and the second limiting seat have a trapezoidal opening structure in the middle, and a slot is provided on both sides of the trapezoidal opening directly below the limiting part.

[0011] By adopting the above technical solution, it is possible to limit the air conditioning manifold and allow the limiting part to move downward normally.

[0012] Both sides of the first and second limiting seats are equipped with slide rails, and the correction component slides along the slide rails. A connecting rod that can be inserted into the first limiting seat is also fixed at one end of the second limiting seat.

[0013] By adopting the above technical solution, it is possible to stably place the air conditioning manifold.

[0014] The adjustment part has recessed keys on both sides, and the slide has a through hole in the middle that matches the outer wall of the adjustment part.

[0015] By adopting the above technical solution, the adjusting part can move stably up and down without rotating.

[0016] The limiting end is a truncated cone structure, and the vertical center axis of the limiting end, the vertical center axis of the deburring machine output end, the center axis of the trapezoidal opening of the limiting seat one, and the center axis of the trapezoidal opening of the limiting seat two are on the same vertical section.

[0017] By adopting the above technical solution, the air conditioning manifold is limited and its connection holes are deburred.

[0018] The beneficial effects of this utility model's pre-welding end treatment fixture for air conditioning manifolds are:

[0019] This device facilitates the placement and positioning of the air conditioning manifold, preventing it from shaking and causing the connection holes to become misaligned, which would affect subsequent deburring. It also automatically deburrs the connection points of the air conditioning manifold, saving manpower and ensuring more uniform deburring. Attached Figure Description

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0025] Reference Figure 1-3 A pre-welding end treatment fixture for air conditioning manifold includes a workbench 1 and a positioning mechanism and an end treatment mechanism installed on the workbench 1. The positioning mechanism includes a first limit seat 2, a second limit seat 3, an electric cylinder 4, a pneumatic cylinder 5, a limiting part 6, and a correction component 7. The first limit seat 2 is fixed on the workbench 1, and the second limit seat 3 slides along the track groove 101. The electric cylinder 4 is installed at the bottom of the workbench 1, and its output end is fixedly connected to the bottom of the second limit seat 3 through a connecting plate that passes through the slide groove 102. There are two sets of pneumatic cylinders 5, which are respectively installed at one end of the first limit seat 2 and the second limit seat 3. The limiting part 6 is installed at the output end of the pneumatic cylinder 5. There are two sets of correction components 7, which are respectively slidably installed on the first limit seat 2 and the second limit seat 3.

[0026] The correction component 7 includes a slide 701, an adjustment part 702, a first limiting end 703, a spring 704, and a second limiting end 705. The adjustment part 702 is slidably disposed in the middle of the slide 701. The first limiting end 703 is installed at the bottom of the adjustment part 702. The second limiting end 705 is elastically installed on the slide 701 by the spring 704. One end of the second limiting end 705 can be inserted into the through hole 7021 in the adjustment part 702.

[0027] Place the air conditioning manifold in the middle of the first limiting seat 2 and the second limiting seat 3, and set the connecting port on the side of the air conditioning manifold facing upward. Then drive the electric cylinder 4 to pull the second limiting seat 3, and move the bottom along the track groove 101 and the slide groove 102 until the air conditioning manifold is clamped from both ends by the first limiting seat 2 and the second limiting seat 3.

[0028] Move the correction component 7 so that the first limiting end 703 moves above one of the connection ports of the air conditioning manifold. Pull the second limiting end 705 so that the second limiting end 705 disengages from the through hole 7021. The adjustment part 702 and the first limiting end 703 move downward under gravity. At this time, the bottom of the first limiting end 703 is embedded in the connection port of the air conditioning manifold.

[0029] Next, drive cylinder 5 pushes limit part 6 to move downward, and limit part 6 applies a certain pressure to both ends of air conditioning manifold to ensure that air conditioning manifold does not sway in the middle of limit seat 1 2 and limit seat 2 3.

[0030] The port processing mechanism includes a first motor 8, a first lead screw 9, a guide rail 10, a moving base 11, a second motor 12, a second lead screw 13, a moving plate 14, and a deburring machine 15. The first lead screw 9 is installed at the output end of the first motor 8. The moving base 11 is connected to the first lead screw 9 and moves laterally along the guide rail 10. The second motor 12 is installed on the moving base 11. The second lead screw 13 is installed at the output end of the second motor 12. The moving plate 14 is connected to the second lead screw 13 and slides along the moving base 11. The deburring machine 15 is installed on the moving plate 14. The first motor 8 can be driven to move the moving base 11 along the guide rail 10 through the first lead screw 9, so that the output end of the deburring machine 15 moves above the connection port of the air conditioning manifold. This drives the deburring machine 15 and the second motor 12 to move the moving plate 14 downward through the second lead screw 13, thereby controlling the deburring machine 15 downward. This allows the deburring machine 15 to deburr the connection port of the air conditioning manifold through its output end.

[0031] The adjustment part 702 has recessed keys on both sides, and the slide 701 has a through hole in the middle that matches the outer wall of the adjustment part 702. After the other connection ports of the air conditioning manifold are processed, the adjustment part 702 can be lifted upward to disengage the first limiting end 703 from the connection port of the air conditioning manifold until the through hole 7021 is lifted above the slide 701. At this time, the second limiting end 705 is pushed into the through hole 7021 by the elastic force of the spring 704, thus preventing the first limiting end 703 from moving downward under gravity.

[0032] Then, control the deburring machine 15 to deburr the remaining air conditioning manifold connection.

[0033] This device facilitates the placement and positioning of the air conditioning manifold, preventing it from shaking. It also automatically deburrs the connection points of the air conditioning manifold, saving manpower and ensuring more even deburring.

[0034] Both the first limiting seat 2 and the second limiting seat 3 have a trapezoidal opening in the middle, and a slot 103 is provided on both sides of the trapezoidal opening directly below the limiting part 6. Both sides of the first limiting seat 2 and the second limiting seat 3 are equipped with slide rails, and the straightening component 7 slides along the slide rails. A connecting rod that can be inserted into the first limiting seat 2 is fixed at one end of the second limiting seat 3. The two ends of the air conditioning manifold can be limited by adjusting the distance between the first limiting seat 2 and the second limiting seat 3, while the straightening component 7 can keep the position of the connection hole of the air conditioning manifold in place, preventing the air conditioning manifold from rotating and the connection hole from shifting.

[0035] The limiting end 703 is designed as an inverted frustum structure, and the vertical center axis of the limiting end 703, the vertical center axis of the output end of the deburring machine 15, the center axis of the trapezoidal opening of the limiting seat 2, and the center axis of the trapezoidal opening of the limiting seat 3 are on the same vertical section; this ensures that the air conditioning manifold is placed accurately and without deviation, thereby deburring the connecting hole of the air conditioning manifold.

[0036] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
