Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger processing technology, and in particular relates to a positioning and opening device for a heat exchanger connecting plate. Background Technology

[0002] The heat exchanger connecting plate is a key connecting component of the heat exchanger. It is mostly strip-shaped and is mainly used to fix the heat exchange core, seal the medium passage and transfer the load. When processing it, markings are usually drawn on its surface and then holes are drilled in it using a drilling machine.

[0003] Currently, most heat exchanger connecting plates are drilled using drilling machines. When drilling heat exchanger connecting plates, the impact of the drill bit causes vibration, which can lead to displacement of the drilling position or rough hole walls. Therefore, a positioning and drilling device for heat exchanger connecting plates is needed. The positioning structure can fix the heat exchanger connecting plate, prevent it from shifting during drilling, and ensure the stability of the heat exchanger connecting plate during processing. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning and drilling device for a heat exchanger connecting plate, which can fix the heat exchanger connecting plate through a positioning structure, prevent the heat exchanger connecting plate from shifting during drilling, and ensure the stability of the heat exchanger connecting plate during processing, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A positioning and opening device for a heat exchanger connecting plate includes a radial drilling machine. A processing table is provided on the surface of the radial drilling machine. Two symmetrical adjusting frames are provided on the top of the processing table. A sliding groove is opened on the top of the adjusting frame. A threaded rod is rotatably connected to the inner cavity of the sliding groove. A slide is slidably connected to the inner cavity of the sliding groove. The threaded rod passes through the slide and is threadedly connected to the slide. A threaded rod is passed through the top of the slide. The slide is threadedly connected to the threaded rod. A pressure plate is fixedly connected to the bottom of the threaded rod. A torsion block is fixedly connected to the top of the threaded rod. Two symmetrical sliders are fixedly connected to the bottom of the adjusting frame. A connecting plate is fixedly connected to both the front and back of the processing table. A sliding groove is opened on the top of the connecting plate. The slider is adapted to the sliding groove. A fixing plate is fixedly connected to the front of the adjusting frame. A threaded rod is passed through the front of the fixing plate. The fixing plate is threadedly connected to the threaded rod. A torsion block is fixedly connected to the front of the threaded rod.

[0006] Preferably, an anti-slip plate is fixedly connected to the bottom of the pressure plate. The anti-slip plate is circular and is located above the processing table.

[0007] Preferably, the front of the threaded rod extends through to the outside of the slide groove and is fixedly connected to a torsion block three, and two symmetrical fixing plates are fixedly connected to the surface of the torsion block three.

[0008] Preferably, the surface of the torsion block is fixedly connected to two symmetrical fixing rods, and the cross-section of the slider is I-shaped.

[0009] Preferably, one of the connecting plates has anti-slip texture on its front side, the fixing plate is L-shaped, and the threaded rod is in contact with the connecting plate.

[0010] The beneficial effects of this utility model are: 1. This utility model achieves the goal of fixing the heat exchanger connecting plate through a positioning structure by placing the heat exchanger connecting plate on the top of the processing table, moving the adjusting bracket to the appropriate position, rotating the second torsion block to limit the adjusting bracket, rotating the third torsion block to move the slide to the appropriate position, and rotating the first torsion block to move the pressure plate downward to press and fix the heat exchanger connecting plate. This prevents the heat exchanger connecting plate from shifting during drilling and ensures the stability of the heat exchanger connecting plate during processing. 2. By setting anti-slip plates, this utility model increases the friction between the pressure plate and the heat exchanger connecting plate when the pressure plate presses the heat exchanger connecting plate, preventing the heat exchanger connecting plate from sliding at the bottom of the pressure plate and increasing the stability of the heat exchanger connecting plate on the top of the processing table.
