The refrigerant then absorbs heat in the evaporator to achieve the cooling effect. The expansion valve controls the valve flow through the change of superheat at the end of the evaporator to prevent insufficient utilization of the evaporator area and knocking.
[0003] The expansion valve needs to be fixed by a clamping device during the processing; the existing processing fixtures for the expansion valve body easily result in some positions on the expansion valve being unable to be processed, and the processing range is not comprehensive.

[0025] In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.
[0026] like Figure 1-Figure 5 As shown, the utility model provides a clamping device for automobile air conditioning expansion valve body processing, including a base 10, the base 10 is fixedly mounted on a workbench, and two side plates 11 are fixedly mounted on the base 10. The above contents are all prior art, and the specific structure is not repeated here. The device also includes a guide rod 20, a clamping mechanism 30 and a driving mechanism 40.
[0027] The guide rod 20 is disposed above the base 10 in the transverse direction, and both ends of the guide rod 20 are fixedly connected to the two side plates 11 respectively.
[0028] There are two clamping mechanisms 30, which are respectively arranged at the two ends of the guide rod 20. The clamping mechanism 30 includes a slider 31, a vertical plate 32, a fixed shaft 33 and a control assembly 50. The slider 31 is arranged on the guide rod 20 and is slidably connected to the guide rod 20. The vertical plate 32 is fixedly installed on the slider 31 in the longitudinal direction. The fixed shaft 33 passes through the vertical plate 32 in the transverse direction and is fixedly connected to the vertical plate 32. The fixed shaft 33 has at least two rectangular grooves 34 arranged in sequence and spaced evenly along the circumferential direction and passing through in the transverse direction. A movable rod 35 is arranged in the rectangular groove 34, and the movable rod 35 extends in the transverse direction. The movable rod 35 is in sliding contact with the inner wall of the rectangular groove 34, and the diameter of the movable rod 35 is the same as the width of the rectangular groove 34. An arc plate 36 is fixedly installed at the end of the first end of the movable rod 35, and the arc plate 36 contacts the inner end surface of the fixed shaft 33, and the opening direction of the arc plate 36 faces the axis of the fixed shaft 33. The control assembly 50 is used to control all the movable rods 35 to move inward or outward synchronously.
[0029] The driving mechanism 40 is used to control the two clamping mechanisms 30 to move closer to or farther from each other.
[0030] In the initial state, the two clamping mechanisms 30 are in a state of being away from each other.
[0031] The specific use process is as follows: first, the staff holds the expansion valve body and places it horizontally between the two clamping mechanisms 30. Then the staff controls the drive mechanism 40 to start, and the drive mechanism 40 controls the two clamping mechanisms 30 to move closer to each other until the arc plates 36 in the two clamping mechanisms 30 are inserted into the ports at both ends of the expansion valve body, and at this time, the vertical plate 32 contacts the end surface of the expansion valve body. Then the staff starts the control component 50, and the control component 50 controls all the movable rods 35 to move outward synchronously until the arc plates 36 are pressed against the inner wall of the expansion valve body. At this time, the two clamping mechanisms 30 can fix the expansion valve body, thereby completing the fixation of the expansion valve body, and the processing equipment can then process the expansion valve body.
[0032] Since all the arc plates 36 are located inside the expansion valve body at this time, they will not cause any obstruction to the processing equipment, and the processing equipment can smoothly process the expansion valve body, and the processing range is larger and more comprehensive.
[0033] After the processing is completed, the staff controls all the movable rods 35 to move inward synchronously through the control component 50, so that the arc plate 36 is out of contact with the inner wall of the expansion valve body, and then controls the two clamping mechanisms 30 to move away from each other through the driving mechanism 40 to remove the expansion valve body, and the device returns to the initial state.
[0034] In one embodiment, the outer circumference of the fixed shaft 33 has an external thread. The control assembly 50 includes a cap 51. The cap 51 covers the outer end surface of the fixed shaft 33, and the inner circumference of the cap 51 has an internal thread, and the cap 51 is threadedly connected to the fixed shaft 33. At least two arc-shaped guide grooves 52 are formed on the end surface of the cap 51, which penetrate in the transverse direction and extend in the radial direction of the cap 51, and the width of the arc-shaped guide grooves 52 is the same as the diameter of the movable rod 35. The arc-shaped guide grooves 52 are arranged one by one with the rectangular grooves 34, and the inner wall of the arc-shaped guide grooves 52 is in sliding contact with the corresponding movable rod 35.
[0035] When the staff rotates the cap 51 counterclockwise by hand, since the arc-shaped guide groove 52 extends along the radial direction of the cap 51, under the action of the rectangular groove 34, all the movable rods 35 will move outward synchronously until the arc-shaped plate 36 is pressed against the inner wall of the expansion valve body. Conversely, when the processing is completed, when the staff rotates the cap 51 clockwise by hand, since the arc-shaped guide groove 52 extends along the radial direction of the cap 51, under the action of the rectangular groove 34, all the movable rods 35 will move inward synchronously, and the arc-shaped plate 36 will be out of contact with the inner wall of the expansion valve body. The staff can control the two clamping mechanisms 30 to move away from each other through the driving mechanism 40 to remove the expansion valve body.
[0036] Since the cap 51 is threadedly connected to the fixed shaft 33, the cap 51 will be in a fixed state after the staff loosens the cap 51, thereby making the device more stable and preventing the cap 51 from rotating automatically due to vibration when the processing equipment processes the expansion valve body.
[0037] The control assembly 50 has an ingenious structure and is easy to operate. The operator only needs to control the rotation of the cover cap 51 to control all the arc plates 36 to move synchronously.
[0038] In one embodiment, a baffle 37 is fixedly mounted on the end of the second end of the movable rod 35 , and a spring 38 is disposed between the baffle 37 and the cover cap 51 , so that the spring 38 makes the baffle 37 tend to move outward.
[0039] Under the action of the spring 38, the arc plate 36 always maintains a tight contact with the inner end surface of the fixed shaft 33, so that even if the staff rotates the cap 51, the arc plate 36 can always remain stable in the horizontal direction and will not shake in the horizontal direction, further improving the stability of the device.
[0040] In one embodiment, the driving mechanism 40 includes a bidirectional lead screw 41 and a motor 42. The bidirectional lead screw 41 is disposed above the base 10 in the horizontal direction, and its two ends are respectively connected to the two side plates 11 for rotation, and the bidirectional lead screw 41 is parallel to the guide rod 20. The screw threads at the two ends of the bidirectional lead screw 41 have opposite spiral directions, and the two ends of the bidirectional lead screw 41 are respectively connected to the two sliders 31 for threading. The motor 42 is fixedly mounted on one of the side plates 11, and is used to control the rotation of the bidirectional lead screw 41, and the motor 42 is electrically connected to the control cabinet.
[0041] The staff controls the motor 42 to start through the control cabinet, and the motor 42 drives the bidirectional lead screw 41 to rotate, and the two clamping mechanisms 30 will move closer to or farther from each other under the action of the guide rod 20. The driving mechanism 40 has a simple structure, is easy to operate, and can reduce manufacturing costs.
[0042] In one embodiment, a rubber pad is fixedly mounted on the outer surface of the arc plate 36. The design of the rubber pad can increase the friction coefficient between the arc plate 36 and the expansion valve body, making the clamping of the expansion valve body more stable; on the other hand, it can prevent the arc plate 36 from directly contacting the expansion valve body, thereby protecting the expansion valve body.
[0043] In one embodiment, three rectangular grooves 34 are formed on the fixed shaft 33, and the three rectangular grooves 34 are arranged at equal intervals along the circumference of the fixed shaft 33. Correspondingly, the number of the arc-shaped guide grooves 52 on the cover cap 51 is also three.
[0044] In one embodiment, the spring 38 is sleeved on the movable rod 35 to prevent the spring 38 from bending, thereby further improving the stability of the device.
[0045] The above shows and describes the basic principle, main features and advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
[0046] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
