Description

Technical Field

[0001] This utility model relates to the field of air conditioning pipe production technology, and in particular to a force-enhancing clamping mechanism. Background Technology

[0002] Air conditioning pipes are specially designed for use in air conditioners and refrigeration system heat exchangers, offering excellent heat dissipation performance. To meet the installation requirements of air conditioners, air conditioning pipes require processing during production. Clamping components are used to hold the air conditioning pipes during processing, ensuring greater stability.

[0003] Existing devices often use cylinders to push clamping blocks to hold air conditioning pipes during processing. This results in insufficient clamping force and reduced stability of the clamping. Furthermore, existing clamping devices are often only suitable for one type of air conditioning pipe, so different devices must be used when other types of air conditioning pipes need to be clamped, which is very troublesome.

[0023] like Figure 1-3 As shown, the present invention proposes a force-enhancing clamping mechanism, including a base plate 1, a mounting base 3, and a fixed base 4. The mounting base 3 and the fixed base 4 are spaced apart on the base plate 1. The mounting base 3 is slidably connected to the base plate 1. The base plate 1 is provided with a force-enhancing drive component for driving the mounting base 3 to move closer to or away from the fixed base 4. The mounting base 3 and the fixed base 4 are each detachably provided with a clamping mold 5 for clamping the workpiece at their respective ends that are close to each other.

[0024] In this invention, when the device is needed, the workpiece with clamping is placed between the mounting base 3 and the fixed base 4. The driving component effectively drives the mounting base 3 to move closer to the fixed base 4. The movement of the mounting base 3 drives the clamping mold 5 to move. The two clamping molds 5 cooperate to clamp the workpiece. Furthermore, the device can be disassembled from the mounting base 3 and the fixed base 4 according to different workpiece models, thereby replacing the clamping mold 5 corresponding to different workpieces. The device can effectively clamp the workpiece, and the force-enhancing driving component can increase the clamping force of the mounting base 3 and the fixed base 4, thereby further improving the stability of the workpiece clamping. In use, the device can replace different clamping molds 5 according to different workpieces, thus enabling the device to clamp various different types of workpieces, thereby effectively improving the application range of the device.

[0025] In an optional embodiment, a dovetail block 6 is further included. The mounting base 3 and the fixing base 4 each have a first notch at their adjacent ends. The dovetail block 6 is slidably disposed within the first notch. A first limiting unit for limiting the dovetail block 6 is provided within the first notch. The clamping mold 5 has a second notch at its end facing the dovetail block 6. The dovetail block 6 is slidably disposed within the second notch. A second limiting unit for limiting the clamping mold 5 is provided on the dovetail block 6. By inserting the dovetail block 6 into the second notch, based on the shape of the dovetail block 6, the dovetail block 6 and the clamping mold 5 can be initially limited. Further limiting can be achieved under the action of the second limiting unit. Furthermore, under the action of the first limiting unit, the installation of the dovetail block 6 and the mounting base 3 can be effectively completed, thereby completing the installation of the clamping mold 5.

[0026] In an optional embodiment, the first limiting unit includes a first bolt 17, the inner wall of the first notch is provided with a first threaded blind hole, the dovetail block 6 is provided with a variable diameter hole corresponding to the first threaded blind hole, one end of the first bolt 17 passes through the variable diameter hole and extends into the first threaded blind hole, the first bolt 17 is threadedly connected to the mounting base 3, the first bolt 17 can be moved to abut against the inner wall of the variable diameter hole, by rotating the first bolt 17 into the first threaded blind hole and abutting against the inner wall of the variable diameter hole, the dovetail block 6 can be further limited, thereby improving the stability of the dovetail block 6 installation.

[0027] In an optional embodiment, the second limiting unit includes a limiting block 15, which is connected to one end of the dovetail block 6. The other end of the dovetail block 6 away from the limiting block 15 is provided with a second threaded blind hole. A second bolt is threaded in the second threaded blind hole. One end of the clamping mold 5 is movable to abut against the limiting block 15, and the second bolt is movable to abut against the end of the clamping mold 5 away from the limiting block 15. The limiting block 15 can limit the position of the clamping mold 5 when the second notch on the clamping mold 5 is inserted into the dovetail block 6. By rotating the second bolt, it can be rotated into the second threaded blind hole. By rotating the second bolt, it can be rotated to abut against the clamping mold 5, thereby completing the installation limiting of the clamping mold 5 in conjunction with the limiting block 15.

[0028] In an optional embodiment, the drive assembly includes a support base 2, a first connecting rod 7, a second connecting rod 9, a cylinder connector 11, and a cylinder 12. The support base 2 is connected to the base plate 1 and is located on the side of the mounting base 3 away from the fixed base 4. The support base 2 has a third notch at one end facing the mounting base 3, and the mounting base 3 has a fourth notch at one end facing the support base 2. The first connecting rod 7 is located in the fourth notch and is rotatably connected to the mounting base 3 via a first rotating shaft 8. The second connecting rod 9 is located in the third notch and is rotatably connected to the support base 2.

The cylinder connector 11, the first connecting rod 7, and the second connecting rod 9 are rotatably connected by the second rotating shaft 10. The cylinder connector 11 is moved by the cylinder 12. The movement of the cylinder connector 11 will drive the first connecting rod 7 and the second connecting rod 9, which are rotatably connected to it, to move. Since the second connecting rod 9 is rotatably connected to the mounting seat 3, it can effectively drive the mounting seat 3 to move. The first connecting rod 7 and the second connecting rod 9 are rotatably connected to each other by the second rotating shaft 10 to form a rocker linkage mechanism, which can effectively improve the driving force of the first connecting rod 7 on the mounting seat 3, thereby further improving the stability of clamping the workpiece.

The two mounting arms 13 are respectively connected to the base plate 1 and the support seat 2, and are spaced apart from each other.
