Description

Technical Field

[0001] The utility model relates to a processing device for a refrigerant flow channel plate of a heat exchange system, belonging to the field of machining. Background Art

[0002] Aluminum alloy workpieces in hot die forging production, especially those with large areas, thin walls and complex shapes, place higher demands on processing technology. Traditional machining methods, such as using a clamp to fix the workpiece on the fixture, can provide a certain degree of stability, but there are also some obvious limitations. First, this method may occupy the parts to be processed during the clamping process, resulting in these areas being unable to be processed. Secondly, in order to solve this problem, it is usually necessary to re-clamp the workpiece after processing a part to process the remaining part, which not only increases production time and cost, but may also lead to a decrease in machining accuracy.

[0003] For aluminum alloy thin-sheet parts such as the refrigerant flow plate of the heat exchange system, the traditional processing method is also prone to indentation, affecting the appearance and performance of the product. What's more serious is that improper operation during the clamping process may cause the product to deform, which will directly lead to the product failing the subsequent inspection, resulting in a waste of materials and time.

[0004] When the prior art uses a pressure plate to fix the workpiece on the tooling, the part that needs to be processed is usually occupied and cannot be processed; it is necessary to process a part, re-clamp, and then process the unprocessed part. Multiple clamping and positioning will result in reduced processing accuracy, and it is easy to have processing tolerances and reduced production efficiency. The product is relatively soft and is prone to indentation during the clamping process. As a new energy vehicle component, the product has strict appearance requirements and does not allow indentation, bumps, etc. The product is a thin sheet and is easily deformed during the traditional clamping process, resulting in unqualified products after processing.

However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements fall within the scope of protection of the present invention.

[0023] See also Figures 1 to 4 The utility model relates to a processing device for a refrigerant flow channel plate of a heat exchange system, comprising a workbench 9, a workpiece adsorption plate 4, an adsorption assembly and a clamping assembly. The workpiece adsorption plate 4 is installed in the middle of the workbench, and the vacuum adsorption area of ​​the adsorption assembly is formed at the workpiece adsorption plate 4; one of the clamping assemblies is installed on the workbench 9 on both sides of the workpiece adsorption plate 4, and two groups of the clamping assemblies are symmetrically arranged along the workpiece adsorption plate 4; a plurality of plug-in joint mounting holes are arranged on the workpiece adsorption plate 4, and a sealing groove is arranged on the workpiece adsorption plate 4 around the plug-in joint mounting hole, and a sealing ring 11 that fits the workpiece is inserted into the sealing groove.

[0024] Based on the above structure, the utility model realizes:

[0025] Efficient adsorption and fixation: The adsorption component on the workpiece adsorption plate 4 utilizes vacuum adsorption to stably fix the workpiece without the need for traditional pressing plates or clamps, thereby reducing the risk of damage to the workpiece surface during the clamping process.

[0026] Optimized sealing performance: A sealing ring is placed in the sealing groove arranged around the installation hole of the plug connector to improve the sealing performance.

[0027] Reduce processing marks: Since the workpiece is fixed by adsorption rather than mechanical clamping, the possibility of indentation on the workpiece surface during processing is reduced, and the integrity and aesthetics of the workpiece surface are maintained.

[0028] The clamping assembly includes a clamping plate 13, an outer positioning screw 1, an outer adjusting nut 3, an inner positioning screw 7, an inner adjusting nut 6 and a cushion block 1. The outer positioning screw 1 and the inner positioning screw 7 are both installed on the workbench 9. The outer positioning screw 1 is vertically arranged to the workbench 9. The outer positioning screw 1 passes through the cushion block 1 and one end of the clamping plate 13 in sequence and is then installed with the outer adjusting nut 3. The other end of the clamping plate 13 is pressed against the workpiece adsorption plate; a strip hole is provided in the middle of the clamping plate 13 along the length direction of the clamping plate 13; the inner positioning screw 7 is vertically arranged to the workbench 9, and the inner positioning screw 7 passes through the strip hole and is then installed with the inner adjusting nut 6.

[0029] The workpiece adsorption plate 4 is installed on the workbench 9 through a pad 12 , and a gap is formed between two pads 12 .

[0030] Based on the setting of the clamping assembly structure of the present application, the following is achieved:

[0031] Precise positioning: The outer positioning screw 1 and the inner positioning screw 7 are vertically installed on the workbench 9, ensuring the vertical clamping of the clamping plate 13, thereby achieving precise positioning of the workpiece.

[0032] Flexible adjustment: The outer adjusting nut 3 and the inner adjusting nut 6 allow the pressure applied by the clamping plate 13 to be fine-tuned to adapt to workpieces of different thicknesses and shapes, ensuring stability and uniformity during processing.

[0033] Structural stability: The use of pad 1 not only provides additional support, but also helps to disperse the pressure and reduce local deformation of the workpiece during the compaction process.

[0034] Even distribution of clamping force: a strip hole is provided in the middle of the clamping plate 13, so that after the inner positioning screw 7 passes through the strip hole, the clamping force can be more evenly distributed on the clamping plate 13, thereby reducing the deformation of the workpiece.

[0035] Reduce workpiece damage: Since the clamping plate 13 is directly pressed against the workpiece adsorption plate, scratches or indentations on the workpiece surface that may be caused by traditional fixtures are avoided, thereby protecting the integrity of the workpiece.

[0036] Improve processing efficiency: Through precise positioning and uniform clamping force, the movement and vibration of the workpiece during processing are reduced, and the processing efficiency and quality are improved.

The screw head of the outer positioning screw 1 and the screw head of the inner positioning screw are slidably matched with the slide groove 10, and the cross-section of the slide groove is an inverted T-shape.

[0042] The working principle of the utility model is:

[0043] When in use, place the workpiece on the workpiece adsorption plate 4, turn on the vacuum pump, and when the vacuum reaches -65KPa, the workpiece to be processed is firmly adsorbed on the workpiece adsorption plate, turn on the processing equipment, and the workpiece will not move and remain firmly fixed.
