Description

Technical Field

[0001] The present invention relates to the field of metal casting combined processing, and more particularly to a metal casting combined processing device and method. Background Art

[0002] Metal castings refer to metal products formed by pouring molten metal into a mold and allowing it to cool and solidify. This is an important metal forming process that is widely used in various industries. After the initial formation of existing metal castings, they need to undergo fine processing, including milling, drilling, grinding and polishing, and then use combined processing machine tools for processing.

[0003] Existing combination processing machine tools usually use a driving end to adapt to different cutter heads such as milling, drilling, and grinding, so as to complete the combined processing function of castings. However, the driving end of the existing combination processing machine tools can adapt to cutter heads of different diameters, but in the adaptation process, it is impossible to automatically adjust the correspondence between the cooling water output end and the cutter head position after adaptation, which leads to inconsistent cooling assistance effects on the processing area during the processing. At the same time, especially in the grinding process, the grinding cutter head has a larger diameter, which will cause the temperature of the grinding center area to be higher than the edge temperature, and the cooling water can only be cooled from the outside, resulting in insufficient cooling and cooling effect in the center area, affecting the grinding effect, and thus the existing combination processing device needs to be structurally optimized.

[0066] The use process of the metal casting combined processing device proposed in this embodiment is as follows. Based on Example 1, when the metal casting is being polished, the extrusion block on the top of the polishing head unit 12 squeezes the bottom of the second piston base 102, thereby causing the second piston base 102 to move upward and driving the supporting connecting rod 105 to move upward as a whole. The supporting connecting rod 105 drives several groups of first piston bases 101 to move upward inside the second control hole 23. At this time, the upward displacement of the second piston base 102 opens the passages at the upper and lower ends of the first control hole 22, so that the cooling water inside the control chamber 20 can flow through the first control hole 22 to the position of the guide passage 14 inside the polishing head unit 12, and is guided to the middle of the processing area of the polishing head unit 12 through the guide passage 14. In the process of spraying cooling water on the outside of the polishing head unit 12, the central processing area of the polishing head unit 12 is also cooled.

[0067] Furthermore, when only cooling water needs to be transported through the first control hole 22, the extrusion block on the top of the grinding head unit 12 squeezes the second piston base 102 upward, so that the first piston base 101 follows the upward displacement, and the upper end passage of the second control hole 23 is blocked through the upper end of the first piston base 101, thereby realizing the conversion of the cooling water flow direction of the control chamber 20.

[0068] It should be noted that there is no specific restriction on the extrusion block structure at the top of the grinding head unit 12. It can be any existing extrusion protrusion, which is mainly used to squeeze the bottom of the second piston base 102, and the top position structure of the guide passage 14 is adapted to the position structure of the extrusion block to ensure that the cooling water flowing out of the control chamber 20 enters the interior of the guide passage 14, and the top of the grinding head unit 12 and the bottom of the control seat 21 are attached to each other to form a sealing ring.

The middle part of the clamping mechanism can clamp the drill head unit 7, the milling head unit 11, and the grinding head unit 12 respectively according to the processing requirements of the casting, the middle part of the grinding head unit 12 is provided with a guide channel 14 that runs through the upper and lower ends of the grinding head unit 12, and the top of the grinding head unit 12 is provided with an extrusion block;

[0071] The outer side of the support shaft 1 is provided with a water inlet mechanism, which is connected to an external water pipe and is used to transport cooling water to the interior of the control seat 21;

[0072] The interior of the bottom of the support shaft 1 and the interior of the control seat 21 are both provided with a control mechanism 100, which is used to control the direction of the water flow output from the output end of the control seat 21;

[0073] A driving mechanism is provided on the outside of the clamping mechanism, and the driving mechanism is used to drive the clamping mechanism to move.

[0074] A metal casting combined processing method, the processing method steps are as follows:

[0075] Step 1: First, the water inlet mechanism is connected to the external water pipe, and the drill unit 7 to be processed is clamped by the clamping mechanism. At this time, the cooling water supplied to the interior of the control seat 21 by the water inlet mechanism is guided by the control mechanism to spray the processing area of the drill unit 7 from the outside of the drill unit 7;

[0076] Step 2: When the drill unit 7 is finished and replaced with the milling head unit 11, the milling head unit 11 is stably clamped by the clamping mechanism. Due to the different diameters of the milling head unit 11 and the drill unit 7, the displacement distance of the clamping mechanism is different. Through the corresponding cooperation between the clamping mechanism and the control seat 21, the cooling water output end always corresponds to the processing area of the drill unit 7 or the milling head unit 11.

[0077] Step 3: When the metal casting is being polished, the polishing head unit 12 is clamped by the clamping mechanism, and the top of the polishing head unit 12 exerts an upward force on the control mechanism, so that the control mechanism controls the direction of the cooling water delivered from the control seat 21, thereby keeping the center area of the polishing head unit 12 in a cooled state during the polishing process;

[0078] Step 4: Finally, after completing the combined processing of drilling, milling and grinding on the metal casting, the processing requirements of the metal casting are completed.
