Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a composite machining equipment for the housing of an electronic control box for new energy vehicles. Background Technology

[0002] The housing of the electronic control box for new energy vehicles is a component that installs and protects the core electronic control unit of new energy vehicles. Its interior usually contains electronic component mounting positions, heat dissipation channels and interfaces, which requires high machining accuracy. During machining, multiple high-precision planes, hole systems and irregular structures need to be cut. Using a composite machining method that completes multiple processes in one clamping is one way to improve machining position accuracy and increase production efficiency.

[0003] Traditional fixtures typically use external clamping plates, vises, or custom-made clamps to hold and fix the workpiece from the outside. During the clamping process, the operator needs to first place the shell to be processed on the support table or fixture base for initial positioning, and then manually or with the help of tools to lock multiple clamping points in sequence. This process is cumbersome and time-consuming, and the unevenness of manual force application can easily cause slight displacement or deformation of the workpiece during clamping, introducing clamping errors and affecting machining accuracy. Secondly, the step-by-step positioning and locking operations make it difficult to ensure accurate and rapid alignment between the workpiece and the machine tool coordinate system, which brings inconvenience to subsequent tool setting operations. Therefore, this application provides a composite machining equipment for new energy vehicle electronic control box shells to meet the needs. Summary of the Invention

[0004] The purpose of this invention is to provide a composite processing equipment for the housing of a new energy vehicle electronic control box in order to solve the above-mentioned problems. By setting up an insert sleeve with the housing's own shaft hole as the positioning basis, and a pneumatic internal support mechanism triggered by the housing's placement and pressing action, the traditional manual step-by-step positioning and locking operation is replaced. This solves the problems mentioned in the background art, such as the need for initial positioning and then sequentially locking multiple clamping points when using external pressure plates, vises or custom clamps to clamp and fix the workpiece from the outside, which is cumbersome, time-consuming, and introduces clamping errors that affect processing accuracy.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A composite processing equipment for the housing of an electronic control box for new energy vehicles includes a CNC machine tool and a car mounted outside it. A base is slidably mounted on one side of the CNC machine tool. The top of the base is provided with a longitudinal slide table that can slide along the X and Z axes. A fixed table is detachably connected to the top of the longitudinal slide table. A workpiece stage that can rotate along the A and C axes is provided on the fixed table. A receiving platform is detachably connected to the upper surface of the workpiece stage. The receiving platform includes a platform body and a cover plate. A plurality of insertion sleeves are threadedly connected to the top of the cover plate. The insertion sleeves are inserted into the shaft holes of the workpiece to be processed. An internal support mechanism is provided inside the sleeve. The internal support mechanism includes multiple pressure plates arranged axially inside the sleeve. A valve stem is slidably connected inside the sleeve. When the valve stem moves upward, it drives the pressure plates to slide outward, so as to support and fix the workpiece to be processed from the inside. After the workpiece is clamped once, multi-face composite processing can be achieved through the combined movement of the longitudinal slide table and the workpiece table, in conjunction with the machine tool spindle. This avoids the error of multiple clamping. At the same time, the internal support and fixation using the workpiece's own shaft hole provides precise, stable and interference-free clamping conditions for processing.

[0007] Based on the above scheme, the insert sleeve has through slots equidistantly spaced inside, and the pressure plate slides inside the through slots. The end and inner wall of the pressure plate are provided with a first inclined guide surface and a second inclined guide surface. The valve stem includes a rod body and a sealing disc connected together. The outer side and end of the rod body are respectively provided with a first inclined guide platform and a second inclined guide platform adapted to the first and second inclined guide surfaces. Through this design, it can be ensured that during the upward movement of the valve stem, it is pushed from the top and bottom of the pressure plate at the same time, preventing the pressure plate from tilting during the sliding process and ensuring that it expands outward smoothly and evenly.

[0008] Furthermore, the pressure plate has symmetrical arc-shaped grooves inside, and elastic elements are installed in the arc-shaped grooves of multiple pressure plates to drive the pressure plate to slide and reset into the insertion sleeve. The rebound force of the elastic elements can automatically and synchronously pull all the pressure plates radially to retract and reset, so that they quickly separate from the inner wall of the workpiece shaft hole, ensuring that the workpiece can be removed smoothly.

[0009] Optionally, the platform body has an air inlet chamber with a top opening in the middle. A gas channel communicating with the air inlet chamber is provided inside the platform body for injecting high-pressure gas into the air inlet chamber. A movable cap is slidably connected inside the air inlet chamber. A first spring is provided between the movable cap and the bottom wall of the air inlet chamber. Under normal conditions, the first spring lifts the movable cap to close the gas channel. Multiple air passages are symmetrically arranged inside the platform body. When the movable cap and the gas channel are misaligned, high-pressure gas enters the insert sleeve through the air passage. The multiple air passages serve as independent channels from the central air inlet chamber to each insert sleeve. When the main air passage is open, it ensures that high-pressure gas is delivered simultaneously and at equal pressure to all internal support mechanisms, thereby achieving synchronous action of multiple clamping points, ensuring uniform force on the workpiece, and avoiding positioning deviations caused by sequential clamping.

[0010] Compared with the prior art, the present invention has at least the following beneficial effects:

[0011] In the above solution, the new energy vehicle electronic control box housing composite processing equipment provided in this application replaces the traditional manual step-by-step positioning and locking operation by setting up a plug-in sleeve with the housing's own shaft hole as the positioning basis and a pneumatic internal support mechanism triggered by the housing placement and pressing action. After the housing is placed, high-pressure gas synchronously drives all internal support mechanisms, so that the pressure plate supports the housing from the inside. The clamping process is quick and consistent, reducing the error and time consumption caused by human intervention, and providing stable and accurate conditions for subsequent tool setting.

[0012] It is worth mentioning that the internal support fixing using the housing shaft hole ensures that the clamping force is evenly applied to the hole wall, avoiding the housing damage and deformation that may be caused by external pressure. This improves the overall machining accuracy of complex housings. At the same time, the clamping and loosening process is completed automatically by pneumatics. After the high-pressure air is cut off, the housing can be quickly separated from the receiving platform under the action of elastic reset, making it convenient for operators to unload materials.

[0038] like Figures 1 to 3As shown, an embodiment of the present invention provides a composite processing equipment for the housing of a new energy vehicle electronic control box, including a CNC machine tool 1 and a car 101 disposed on its outer side. A base 11 is slidably disposed on one side of the CNC machine tool 1. A longitudinal slide 12 that can slide along the X-axis and Z-axis is provided on the top of the base 11. A fixed table 13 is detachably connected to the top of the longitudinal slide 12. A drive device 111 is disposed on the outer side of the base 11. A crossbeam 113 is fixedly connected inside the base 11. A lead screw 112 is threadedly connected inside the crossbeam 113, and the bottom end of the lead screw 112 is rotatably connected to the base plate of the CNC machine tool 1. The lead screw 112 is driven by the drive device 111. A workpiece table 14 that can rotate along the A-axis and C-axis is provided on the fixed table 13. The longitudinal slide 12, in conjunction with the workpiece table 14, can drive the workpiece... The machining housing moves along four axes. The CNC machine tool 1 is also equipped with a spindle that moves along the Y-axis. With the movement in five axes, the top surface and the sides of the housing can be machined. The CNC machine tool 1 is also equipped with a tool magazine and tool changing mechanism on one side, which can automatically change tools according to machining requirements. The drive device 111 consists of a servo motor and a bevel gear set. The two bevel gears are respectively fixed on the output shaft of the servo motor and the lead screw 112. When the drive device 111 drives the lead screw 112 to rotate, it works with the crossbeam 113 to drive the base 11 to rise and fall along the Y-axis. When the housing rotates around the C-axis, the base 11 moves downwards along the housing by a predetermined distance. The spindle does not need to be raised very high to avoid the outer edge of the housing, which reduces the load on the spindle moving parts and helps to improve the response and positioning accuracy of the spindle movement.

[0039] In this embodiment, as Figures 6 to 8 As shown, the upper surface of the workpiece stage 14 is detachably connected to a receiving platform 2, which includes a platform body 21 and a cover plate 22. The platform body 21 and the cover plate 22 are fixedly connected by bolts.

[0040] The platform 21 has an air inlet chamber 211 with a top opening in the middle. A gas channel 212 connected to the air inlet chamber 211 is provided inside the platform 21 for injecting high-pressure gas into the air inlet chamber 211. A vent pipe (not shown in the figure) is also provided inside the platform 21 for discharging the high-pressure gas from the air inlet chamber 211. A movable cap 213 is slidably connected inside the air inlet chamber 211. A first spring 214 is provided between the movable cap 213 and the bottom wall of the air inlet chamber 211. Under normal conditions, the first spring 214 will... The movable cap 213 lifts and seals the gas passage 212. Multiple gas passages 215 are symmetrically arranged inside the platform 21. When the movable cap 213 is misaligned with the gas passage 212, high-pressure gas enters the insert sleeve 3 through the gas passages 215. A floating platform 221 is slidably connected to the top center of the cover plate 22. A second spring 222 is fixedly connected between the floating platform 221 and the cover plate 22. A pressure rod 223 is fixedly connected to the bottom center of the floating platform 221. The bottom end of the pressure rod 223 penetrates the platform 21 and contacts the top wall of the movable cap 213. Under the action of the first spring 214, the movable cap 213 can be pushed upward. At this time, the side wall of the movable cap 213 seals the air hole of the gas channel 212, preventing high-pressure gas from entering the air inlet chamber 211. At the same time, the second spring 222 drives the floating platform 221 to move to the upper part of the cover plate 22. After the housing is installed and positioned, the bottom of the housing contacts the floating platform 221 and pushes it to move into the cover plate 22. Under the action of pressure, the pressure rod 223 drives the movable cap 213 to move downward and compress the first spring 214. At this time, high-pressure air enters the air inlet chamber 211. Since the plug sleeve 3 is connected to the air passage 215, the high-pressure air in the air inlet chamber 211 enters the plug sleeve 3 simultaneously through multiple air passages 215. With this design, the housing can be positioned and fixed immediately after installation without additional operation, thereby improving the positioning speed of the housing. After the air supply is cut off after processing, the floating table 221 can be driven to move upward and reset under the cooperation of the first spring 214 and the second spring 222, which assists in the unloading of the housing.

[0041] In this embodiment, as Figure 5 and Figure 9As shown, the top of the cover plate 22 is threadedly connected to multiple insertion sleeves 3. The insertion sleeves 3 are inserted into the shaft holes of the workpiece to be processed. An internal support mechanism 5 is provided inside the insertion sleeves 3. The internal support mechanism 5 includes multiple pressure plates 51 axially arrayed inside the insertion sleeves 3. Through slots are equally spaced inside the insertion sleeves 3, and the pressure plates 51 slide inside the through slots. A valve stem 4 is slidably connected inside the insertion sleeves 3. When the valve stem 4 moves upward, it drives the pressure plates 51 to slide outward, so as to support and fix the workpiece to be processed from the inside. The multiple insertion sleeves 3 can be used to position the housing. To assist in preventing it from tilting when it approaches the receiving platform 2, the valve stem 4, under the push of high-pressure air, drives multiple pressure plates 51 to slide outward, so that the arc side of the pressure plate 51 moves from inside the insert sleeve 3 into the shaft hole of the housing, so as to support and fix the housing to be processed from the inside. The internal support mechanism 5 inside the multiple insert sleeves 3 moves synchronously to ensure the consistency of the housing fixation. At the same time, the multiple insert sleeves 3, together with their internal support mechanism 5, can also perform secondary correction of the housing to improve the accuracy of the housing after positioning and fixing, which is convenient for subsequent tool setting and processing.

[0042] like Figure 11 and Figure 12 As shown, the end and inner wall of the pressure plate 51 are provided with a first inclined guide surface 511 and a second inclined guide surface 512. The valve stem 4 includes a rod body and a sealing disc 41 connected together. The outer side and the end of the rod body are respectively provided with a first inclined guide platform 42 and a second inclined guide platform 43 adapted to the first inclined guide surface 511 and the second inclined guide surface 512. By cooperating with the first inclined guide platform 42 and the second inclined guide platform 43, the valve stem 4 can be pushed from the top and bottom of the pressure plate 51 at the same time during the upward movement of the pressure plate 51, preventing the pressure plate 51 from tilting during the sliding process and ensuring the stability of the internal support of the shell.

[0043] like Figure 9 and Figure 10As shown, the pressure plate 51 has symmetrically formed arc-shaped grooves inside. Elastic elements 52 are installed in the arc-shaped grooves of the multiple pressure plates 51 to drive the pressure plates 51 to slide and reset into the insertion sleeve 3. A sliding plate 31 is slidably connected inside the insertion sleeve 3 and above the valve stem 4. A third spring 32 is provided between the sliding plate 31 and the top of the inner wall of the insertion sleeve 3. An air inlet 33 is provided inside the insertion sleeve 3 and below the through groove. The top of the valve stem 4 is always in contact with the bottom wall of the sliding plate 31. When the valve stem 4 moves upward, it pushes the inner support mechanism. At 5 o'clock, the slide plate 31 moves upward and compresses the third spring 32. At the same time, the pressure plate 51 moves outward and stretches the elastic element 52 on its inner side. The elastic element 52 is a ring-shaped rubber ring and is located at both ends of the pressure plate 51. With this design, when the pressure is released, the third spring 32 and the slide plate 31 can quickly push the valve stem 4 in the opposite direction, causing it to move down and reset. The elastic element 52 can drive the pressure plate 51 to slide and reset synchronously to the inside of the insertion sleeve 3, separating it from the shell in time, which facilitates the unloading of the shell after processing.

[0044] Working principle of the invention:

[0045] Place the housing to be processed on the cover plate 22 of the receiving platform 2, align the shaft holes of the housing and fit the corresponding insertion sleeves 3, then press the housing down to press the floating platform 221. The floating platform 221 moves down against the elastic force of the second spring 222, driving the bottom pressing rod 223 to press down the movable cap 213. The movable cap 213 compresses the first spring 214 and moves down in the air inlet chamber 211, causing its side wall to be misaligned with the outlet of the gas channel 212. At this time, the high pressure gas from the external gas source enters the air inlet chamber 211 through the gas channel 212 and is delivered to each insertion sleeve 3 through multiple gas passages 215 connected to it.

[0046] High-pressure gas pushes the valve stem 4 inside the insert sleeve 3 to move upward. During the upward movement of the valve stem 4, the first inclined guide platform 42 on it cooperates with the first inclined guide surface 511, and the second inclined guide platform 43 cooperates with the second inclined guide surface 512. Together, they drive multiple pressure plates 51 to slide radially outward synchronously in the through groove of the insert sleeve 3. The outer surface of the pressure plate 51 supports the inner wall of the housing shaft hole, thereby fixing the workpiece from the inside. At the same time, the pressure plate 51 moves outward and stretches the elastic element 52 inside it, while the valve stem 4 pushes the slide plate 31 upward and compresses the third spring 32.

[0047] After the workpiece is fixed, the CNC machine tool 1 can perform composite machining on it. After the machining is completed, the high-pressure air source is cut off and the vent pipe is opened. The air pressure in the insert sleeve 3 is released. Under the elastic force of the third spring 32, the slide plate 31 pushes the valve rod 4 down to reset. Under the rebound force of the elastic element 52, the pressure plate 51 retracts radially inward to reset and disengages from the inner wall of the housing shaft hole. At the same time, the air pressure in the air inlet chamber 211 drops. Under the elastic force of the first spring 214, the movable cap 213 moves upward to reset and reseals the outlet of the gas channel 212. Under the elastic force of the second spring 222, the floating table 221 drives the pressure rod 223 to move upward to reset the auxiliary housing unloading.

[0048] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0049] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
