[0032] After assembly, the evaporator core needs to be brazed using steel wire binding, usually done with automated binding equipment. However, if the automated binding equipment malfunctions or the steel wire breaks during the binding process, manual binding is required. Binding the core also necessitates positioning and tightening it, an operation that cannot be completed by a single person, thus increasing labor costs.

[0033] Therefore, this embodiment provides a positioning and clamping fixture to solve the above problems, which can reduce labor consumption. It should be noted that... Figure 1 In the diagram, direction ab is the first direction, direction cd is the second direction, and the second direction is perpendicular to the first direction.

[0034] like Figures 1-2 As shown, the positioning and clamping fixture in this embodiment includes a base plate 1 and a clamping assembly. The clamping assembly includes a first positioning member 2, a positioning seat 3 and a clamping member 4. The first positioning member 2 and the positioning seat 3 are both connected to the base plate 1.

[0035] The first positioning member 2 has a first protrusion 21. Optionally, in this embodiment, the first positioning member 2 further includes a positioning strip, which is laid flat on the base plate 1. The first protrusion 21 is connected to the end of the positioning strip and protrudes in a direction perpendicular to the base plate 1 to limit the core 800 placed on the base plate 1.

[0036] Optionally, multiple first positioning members 2 are arranged at intervals along the second direction, and the multiple first protrusions 21 are aligned along the second direction. The multiple first protrusions 21 can ensure more balanced positioning of the core 800, and the core 800 will not deflect. Optionally, in this embodiment, three first positioning members 2 are provided, and the three first positioning members 2 are evenly spaced.

[0037] The base plate 1 has multiple mounting positions 101, which are arranged sequentially at intervals along the first direction. The positioning seat 3 can be selected to be mounted at one of the mounting positions 101. That is, the position of the positioning seat 3 relative to the base plate 1 is adjustable, and the distance between the positioning seat 3 and the first protrusion 21 is adjustable, so as to adapt to cores 800 of different sizes.

[0038] Optionally, the clamping assembly also includes a second positioning element 5. A first positioning hole is provided at each mounting position 101 of the base plate 1, and a second positioning hole is provided on the positioning seat 3.

[0040] The clamping member 4 is connected to the positioning seat 3, and the position of the clamping member 4 relative to the positioning seat 3 along the first direction is adjustable. The first protrusion 21 is provided at one end of the base plate 1 along the first direction, and the clamping member 4 is located at the other end of the base plate 1 along the first direction. The gap between the first protrusion 21 and the clamping member 4 is used to place the core 800. The first protrusion 21 and the clamping member 4 can jointly position and clamp the core 800, that is, there is no need for manual clamping of the core 800, which can save manpower and reduce labor costs.

[0041] Optionally, the positioning seat 3 has a threaded hole extending through it in the first direction, and the clamping member 4 has a threaded rod 41 extending in the first direction. The threaded rod 41 is threadedly engaged with the threaded hole so that the position of the clamping member 4 relative to the positioning seat 3 in the first direction can be adjusted. That is, the distance between the clamping member 4 and the first protrusion 21 can be adjusted to achieve the limiting, fixing and clamping of the core 800 by the clamping member 4.

[0042] Optionally, in some embodiments, a turntable 42 is provided at the end of the threaded rod 41 away from the first protrusion 21 to facilitate manual operation. When the operator rotates the turntable 42, the threaded rod 41 can be rotated along its own axis, and the threaded rod 41 moves relative to the positioning seat 3, and the clamping member 4 moves relative to the positioning seat 3.

[0043] Optionally, in other embodiments, the clamping assembly further includes a rotation drive, with the threaded rod 41 connected to the output end of the rotation drive, which can drive the threaded rod 41 to rotate along its own axial direction.

The axial direction of the bearing 44 is the first direction. That is, when the threaded rod 41 rotates, the clamping head 43 is driven to move by means of the bearing 44. After the clamping head 43 has contacted the core 800, it will not rotate to avoid scratching the core 800.

[0045] Optionally, the clamping member 4 has a plurality of clamping portions 431, that is, the clamping head 43 has a plurality of clamping portions 431, all of which protrude along a first direction to press against the core 800, and the plurality of clamping portions 431 are arranged sequentially at intervals along a second direction, the second direction being perpendicular to the first direction.

[0046] Optionally, in some embodiments, the clamping assembly further includes a first pressure sensor. The test end of the first pressure sensor is disposed on the surface of the clamping member 4 that presses against the core 800. The first pressure sensor is used to detect the pressure between the clamping member 4 and the core 800. Based on the pressure test results, it can be determined whether the core 800 is clamped in place, thereby increasing the accuracy of the clamping operation and further improving the clamping quality of the core 800.

[0047] Optionally, the clamping assembly also includes a second pressure sensor, the test end of which is disposed on the surface of the first protrusion 21 pressing against the core 800. The second pressure sensor is used to detect the pressure between the first protrusion 21 and the core 800.

[0048] Optionally, the positioning and clamping fixture further includes a positioning assembly, which includes a first limiting member 6 and a second limiting member 7, both connected to the base plate 1. The first limiting member 6 and the second limiting member 7 are spaced apart and opposite to each other along a second direction, and the gap between the first limiting member 6 and the second limiting member 7 is used to place the core 800. That is, the first protrusion 21 and the clamping member 4 are respectively located at both ends of the core 800 along the first direction, and the first limiting member 6 and the second limiting member 7 are respectively located at both ends of the core 800 along the second direction. The first limiting member 6 is fixedly mounted on the base plate 1 by bolts, and the position of the second limiting member 7 relative to the base plate 1 along the second direction is adjustable.

[0049] Optionally, both the first limiting member 6 and the second limiting member 7 have a second protrusion, which protrudes in a direction perpendicular to the base plate 1 to increase the contact area with the side of the core 800. Optionally, both the first limiting member 6 and the second limiting member 7 have a plurality of second protrusions arranged at intervals along a first direction.

[0050] Optionally, the base plate 1 has multiple assembly positions 102, which are arranged sequentially at intervals along the second direction, and the second limiting member 7 can be selectively disposed at one of the assembly positions 102.

[0051] Optionally, a third positioning hole is provided at each assembly position 102 of the base plate 1, and a fourth positioning hole is provided on the second limiting member 7. The third positioning member passes through the third positioning hole and the fourth positioning hole in sequence, thereby realizing the rapid assembly of the second limiting member 7 on the base plate 1. Optionally, the third positioning member is a positioning pin, and both the third positioning hole and the fourth positioning hole are pin holes.

[0052] By using this positioning and clamping fixture to clamp the core 800, the operator can wrap the steel wire 801 around the core 800 and tighten the steel wire 801, saving manpower and preventing some cores 800 from being insufficiently clamped due to differences in manual operation, which helps to improve the quality of the core 800.
