Description

Technical Field

[0001] This invention relates to the field of flow channel plate positioning fixture technology, and more specifically, to a laser cutting fixture for automatically feeding flow channel plates. Background Technology

[0002] During the prototyping process of new cold-rolled steel plate samples, the cold-rolled steel plate is usually assembled from a flow channel plate, a flat plate, and two inlet and outlet connectors. The flow channel plate needs to be stamped into shape using a simple mold first, and then laser-cut to obtain the final product. When laser-cutting the flow channel plate, tooling must be used to fix its position to ensure cutting accuracy.

[0003] Existing flow channel plate fixtures require operators to manually place the flow channel plates onto the fixture. After the previous flow channel plate is machined, it needs to cool down before the operator can remove it and place the next flow channel plate. The machining smoothness between two adjacent flow channel plates is low, which affects the machining efficiency. Summary of the Invention

[0004] The present invention aims to solve the problem that existing flow channel plate tooling requires manual insertion by operators, resulting in low processing efficiency.

[0005] To address the above problems, this invention provides an automated feeding laser cutting fixture for flow channel plates, comprising: A substrate is provided with a through hole for a flow channel plate to pass through. A pre-clamping member is provided at the position of the through hole on the substrate. A support plate is also slidably provided on the substrate. The support plate is provided with a positioning groove adapted to the flow channel plate. The support plate can be moved to the lower part of the through hole so that the flow channel plate clamped by the pre-clamping member is placed in the positioning groove of the support plate. A feeding assembly is provided with a placement area for placing a flow channel plate. The feeding assembly is movably disposed below the through hole to feed the flow channel plate placed in the placement area to the through hole.

[0006] The present invention provides an automatic feeding laser cutting fixture for flow channel plates, which, compared with the prior art, has the following beneficial effects, but is not limited to: The loading process of the flow channel plate is as follows: The flow channel plate is placed on the placement area of ​​the feeding assembly. The feeding assembly moves upward, driving the flow channel plate upward so that it passes through the through hole. Then, the pre-clamping component actuates to clamp the flow channel plate passing through the through hole. The feeding assembly then moves downward to reset. Subsequently, the support plate moves to the underside of the clamped flow channel plate, aligning the positioning groove with the clamped flow channel plate. The pre-clamping component then releases its grip on the flow channel plate, allowing it to be placed into the positioning groove. The flow channel plate is then cut using laser cutting equipment. After cutting, the support plate... The plate moves to the side of the through hole to cool the processed flow channel plate. At the same time, the feeding component rises and sends the next flow channel plate to be processed to the upper part of the through hole and clamps it with the pre-clamping component. After the flow channel plate that has been cut and processed is cooled, it is taken out. The support plate moves back to the lower part of the flow channel plate clamped by the pre-clamping component. This cycle is repeated to complete the cutting and processing of all flow channel plates. This design of flow channel plate feeding method replaces the traditional manual feeding, reduces the labor intensity of operators, improves the smoothness of processing between adjacent flow channel plates, and improves processing efficiency.

[0023] See Figures 1 to 6 An automatic feeding laser cutting fixture for flow channel plates according to an embodiment of the present invention includes: The substrate 1 has a through hole 11 for the flow channel plate to pass through. The substrate 1 has a pre-clamping member 12 at the position of the through hole 11. The substrate 1 also has a support plate 13 slidably disposed on the substrate 1. The support plate 13 has a positioning groove 131 adapted to the flow channel plate. The support plate 13 can be moved to the lower part of the through hole 11 so that the flow channel plate clamped by the pre-clamping member 12 is placed in the positioning groove 131 of the support plate 13. The feeding assembly 2 is provided with a placement area 211 for placing the flow channel plate. The feeding assembly 2 is movably disposed at the lower part of the through hole 11 to deliver the flow channel plate placed in the placement area 211 to the through hole 11.

[0024] In this embodiment, the loading process of the flow channel plate is as follows: the flow channel plate is placed on the placement area 211 of the feeding assembly 2. The feeding assembly 2 moves upward, driving the flow channel plate upward so that the flow channel plate passes through the through hole 11. Then, the pre-clamping member 12 actuates to clamp the flow channel plate passing through the through hole 11. Then, the feeding assembly 2 moves downward to reset. Subsequently, the support plate 13 moves to the lower part of the clamped flow channel plate, aligning the positioning groove 131 with the clamped flow channel plate. Then, the pre-clamping member 12 releases its clamp on the flow channel plate, allowing the flow channel plate to be placed into the positioning groove 131. Then, the flow channel plate is cut using a laser cutting device. After processing, the support plate 13 moves to the side of the through hole 11 to cool the processed flow channel plate. At the same time, the feeding component 2 rises and sends the next flow channel plate to be processed to the upper part of the through hole 11 and clamps it with the pre-clamping member 12. After the flow channel plate that has been cut and processed has cooled down, it is taken out. The support plate 13 moves back to the lower part of the flow channel plate clamped by the pre-clamping member 12. This cycle is repeated to complete the cutting and processing of the flow channel plate. This design of the flow channel plate feeding method replaces the traditional manual feeding, reduces the labor intensity of operators, improves the smoothness of processing two adjacent flow channel plates, and improves processing efficiency.

[0025] When the flow channel plate is placed in the placement area 211, multiple flow channel plates are placed in a stacked manner. During feeding, the pre-clamping member 12 only clamps the uppermost flow channel plate to achieve feeding of the flow channel plate. In this way, the operator does not need to frequently place the flow channel plate in the placement area 211.

[0026] As a preferred option, refer to Figure 1 The pre-clamping member 12 includes a clamping plate 121 slidably disposed on the substrate 1. There are two clamping plates 121 symmetrically disposed on both sides of the through hole 11. The pre-clamping member 12 also includes a first cylinder 122 fixed on the substrate 1. The first cylinder 122 is connected to the clamping plate 121 to drive the clamping plate 121 to slide on the substrate 1.

[0027] In this embodiment, the pre-clamping member 12 includes clamping plates 121 symmetrically arranged on both sides of the through hole 11. The first cylinder 122 that drives the two clamping plates 121 to move is a synchronous cylinder. During clamping, the first cylinder 122 drives the two clamping plates 121 to move closer to each other, and the clamping plates 121 abut against the corresponding side of the flow channel plate to clamp the flow channel plate.

[0028] In addition, the end of the clamping plate 121 near the through hole 11 is specifically designed as a chamfered opening structure, the width of which is the same as the width of the flow channel plate, thereby increasing the release area during clamping.

[0029] As a preferred option, refer to Figure 2 The bottom of the positioning groove 131 is provided with a contoured protrusion 132 that adapts to the flow channel of the flow channel plate.

[0030] In this embodiment, the shape and size of the positioning groove 131 are the same as those of the flow channel plate to initially position the flow channel plate. The contoured protrusions 132, which are designed and arranged in the same way as the flow channels of the flow channel plate, specifically correspond to the gaps between adjacent flow channels of the flow channel plate. By extending the contoured protrusions 132 into the gaps between adjacent flow channels, the flow channel plate is further positioned, improving the positioning firmness. More importantly, the contoured protrusions 132 can play a role in wrapping and positioning the flow channels of the flow channel plate, reducing the flow channel deformation problem caused by thermal stress concentration during subsequent laser cutting.

[0031] As a preferred option, refer to Figure 2 A washer 133 is provided at the inner edge of the positioning groove 131. An inlet 134 and a drain 135 are also provided in the positioning groove 131. Specifically, the shape of the washer 133 is adapted to the shape of the skirt of the flow channel plate. The width of the washer 133 is equal to or less than the width of the skirt of the flow channel plate. A step is formed between the washer 133 and the upper edge of the positioning groove 131. The height of the step is greater than the thickness of the skirt of the flow channel plate.

[0032] In this embodiment, the height of the contour protrusion 132 is designed to be greater than the depth of the flow channel of the flow channel plate. After the flow channel plate is placed into the positioning groove 131, there is a gap between the lower surface of the flow channel plate and the bottom of the positioning groove 131. After the cutting is completed, the inlet 134 sends coolant into the gap between the positioning groove 131 and the bottom surface of the flow channel plate. The coolant flows back through the drain 135, and the coolant forms a circulation to cool the cut flow channel plate, so that the flow channel plate can be quickly removed after cutting. This further improves the continuity and smoothness of the processing of two adjacent flow channel plates and improves the processing efficiency.

[0033] As a preferred option, refer to Figure 2 The bottom of the positioning groove 131 is vertically and movably provided with a support block 136, and at least part of the contour protrusion 132 is located on the support block 136.

[0034] In this embodiment, the support block 136 is provided to ensure that the flow channel plate held by the pre-clamping member 12 enters the limiting groove smoothly and accurately. Specifically, when the support plate 13 moves to the lower part of the flow channel plate held by the pre-clamping member 12, the support block 136 rises and contacts the bottom surface of the flow channel plate. Then the pre-clamping member 12 releases its clamping on the flow channel plate, and then the support block 136 drags the flow channel plate slowly into the positioning groove 131.

[0035] Of course, within the positioning groove 131, the precise positioning of the flow channel plate by laser cutting can be achieved by relying on the gravity of the flow channel plate itself, the limiting of the positioning groove 131, and the limiting of the flow channel. In order to further improve the stability of the flow channel plate during laser cutting, a negative pressure adsorption port can be set on the gasket 133 of the flow channel plate. This is a common method in the prior art and will not be described in detail here.

[0036] As a preferred option, refer to Figure 4 The bottom of the positioning groove 131 is provided with a receiving groove 137, and the support block 136 is sealed and disposed in the receiving groove 137.

[0037] In this embodiment, the support block 136 is specifically sealed in the receiving groove 137 by a sealing ring to prevent water leakage. When the support block 136 is placed in the receiving groove 137, the upper surface of the support block 136 is flush with the bottom of the limiting groove.

[0038] As a preferred option, refer to Figure 1 and Figure 3 A second cylinder 14 is provided on the substrate 1. The second cylinder 14 is connected to the support plate 13 to drive the support plate 13 to move on the substrate 1. A third cylinder 138 is also provided on the substrate 1. The third cylinder 138 is connected to the support block 136 to drive the support block 136 to move vertically.

[0039] In this embodiment, the second cylinder 14 is connected to the support plate 13, driving the support plate 13 to move on the base plate 1. The movable end of the third cylinder 138 moves through the bottom of the receiving groove 137 and connects with the support block 136, driving the support block 136 to rise and fall.

[0040] As a preferred option, refer to Figure 1 , Figure 5 and Figure 6 The feeding assembly 2 includes a support plate 21 disposed directly below the through hole 11, and a placement area 211 for placing the flow channel plate is located on the support plate 21. The feeding assembly 2 also includes a fourth cylinder 22, which is connected to the support plate 21 to drive the support plate 21 to move vertically.

[0041] Among them, the upper surface of the support plate 21 is provided with limit blocks 23, and there are multiple limit blocks 23, which together form a placement area 211 for placing the flow channel plate.

[0042] In this embodiment, when the flow channel plate is placed in the placement area 211, the limiting block 23 is located on the flow channel side of the edge of the flow channel plate, forming a horizontal limiting on the flow channel plate. In order to improve the stability of the flow channel plate placement, a negative pressure adsorption port can be provided on the upper surface of the limiting block 23 to adsorb the skirt position of the flow channel plate.

[0043] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
