Description

Technical Field

[0001] This utility model belongs to the field of engine cylinder head processing technology, and in particular relates to a multi-station milling device for automobile engine cylinder heads. Background Art

[0002] Milling refers to cutting a workpiece using a rotating multi-edged cutting tool. It is a high-precision machining method. During operation, the cutting tool rotates and the workpiece moves. The workpiece can also be fixed, but the rotating cutting tool must still move. Milling machines include horizontal milling machines, vertical milling machines, and large gantry milling machines.

[0003] Existing technologies disclose several utility model patents in the field of engine cylinder head processing. Among them, utility model patent application number CN219900381U discloses a milling device for irregularly shaped sheet metal parts, including a milling device body and support legs. A longitudinal adjustment mechanism is fixedly connected to the upper middle of the milling device body. A worktable is installed above the longitudinal adjustment mechanism, and a fixing device is installed above the worktable. The milling device body is also installed above the milling device. The clamping blocks of the fixture can be selected according to the shape of the sheet metal part and fixed to the fixture with bolts. Then, the external power supply of the first motor is connected, and the first motor is started, causing the output shaft of the first motor to drive the connecting rod to rotate. The connecting rod drives the stop rod to move through the slider. In this way, the stop rod can drive the fixture to move, thus allowing the irregularly shaped sheet metal parts to be milled. Furthermore, the fixing of the irregularly shaped sheet metal parts is not affected by the waste generated during cutting, eliminating the need to clean up waste during each fixing and disassembly, making it more convenient and reducing labor intensity.

[0004] The drawbacks of the existing technology are that, during use, the existing equipment is difficult to automatically position the workpiece to be processed, and the chips generated by cutting need to be cleaned by the staff using cleaning tools, which increases the fatigue of the staff's hands and also affects the subsequent production and processing efficiency of the existing equipment.

[0005] Based on this, the present invention designs a multi-station milling device for automobile engine cylinder heads to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that it is difficult to effectively and automatically position the workpiece to be processed, and that the chips generated by cutting need to be cleaned by the workers using cleaning tools, which increases the fatigue of the workers' hands and affects the subsequent production and processing efficiency of the existing equipment. Therefore, a multi-station milling device for automobile engine cylinder heads is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0023] The collection box has a door on the front side, and several buffer blocks are provided on both sides of the two buffer plates that are close to each other.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0025] 1.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-5 First embodiment:

[0036] This utility model provides a technical solution:

[0037] A multi-station milling device for automobile engine cylinder head includes a worktable 1, a fixed seat 2 fixedly connected to the top of the worktable 1, and four limiting grooves 3 opened on the top of the worktable 1.

[0038] The cleaning assembly includes four limiting blocks 4 slidably connected in four limiting grooves 3. Each of the four limiting blocks 4 has a connecting block 5 fixedly connected to its top. Each of the four connecting blocks 5 has two rotating rods 6 hinged to it by pins. Adjacent rotating rods 6 are hinged to each other by pins. Each of the four connecting blocks 5 has a cleaning rod 7 fixedly connected to its bottom. A first electric push rod 8 is fixedly connected to the right side of the right connecting block 5. Each of the four connecting blocks 5 has a support plate 9 fixedly connected to its top. Each of the four support plates 9 has two fixing springs 10 fixedly connected to the side of each support plate that is close to each other.

[0039] The bottom of the fixed base 2 is fixedly connected to a second electric push rod 14, the bottom of the second electric push rod 14 is fixedly connected to a support platform 15, the bottom of the support platform 15 is fixedly connected to a bidirectional guide rail 16, a milling device 17 is slidably connected inside the bidirectional guide rail 16, a control box is provided on the front side of the support platform 15, four support legs are provided on the bottom of the worktable 1, a trough 18 is opened on the top of the worktable 1, a collection box 19 is connected to the bottom of the trough 18, a box door is provided on the front side of the collection box 19, and several buffer blocks are provided on the two adjacent sides of the two buffer plates 13.

[0040] By setting up a limit block 4, a connecting block 5, a rotating rod 6, a cleaning rod 7, and a first electric push rod 8, the device can automatically clean up the debris generated during cutting, avoiding the need for workers to use cleaning tools separately, which would increase the fatigue of workers' hands and ensure the subsequent production and processing efficiency of the device.

[0041] Second embodiment:

[0042] Specifically, such as Figure 3-5 As shown, the first electric push rod 8 is fixedly connected to a support block 11. The two ends of the fixed springs 10 located on the front and rear sides are fixedly connected to clamps 12. The two ends of the fixed springs 10 located on the left and right sides are fixedly connected to buffer plates 13. The support block 11 is fixedly connected to the top of the workbench 1. The two buffer plates 13 are slidably connected through the corresponding support plates 9.

[0043] By setting up a limit block 4, a rotating rod 6, a first electric push rod 8, a support plate 9, a clamping plate 12, and a buffer plate 13, the device can automatically position the engine cylinder head to be processed, avoiding the need for manual positioning that would affect the processing accuracy and ensuring the processing effect of the device.

[0044] Working principle and usage: First, place the engine cylinder head to be processed on the two buffer plates 13. Then, start the first electric push rod 8 to the right. The first electric push rod 8 drives the right connecting block 5 and the limiting block 4 to slide to the right in the limiting groove 3. At the same time, under the action of the pin, it drives the two corresponding rotating rods 6 to rotate in opposite directions. This causes the connecting blocks 5 on the front and rear sides to drive the cleaning rod 7, the limiting block 4 and the support plate 9 to move synchronously in the limiting groove 3. This allows the fixing springs 10 and the clamping plates 12 on the front and rear sides to move the engine cylinder head on the front and rear sides. After positioning, the first electric push rod 8 is activated to the left, so that the two buffer plates 13 can buffer and limit the left and right sides of the engine cylinder head. Then, the second electric push rod 14 is activated, which can drive the support table 15, the bidirectional guide rail 16 and the milling device 17 to move downward synchronously. The milling device 17 can process the engine cylinder head through the bidirectional guide rail 16, and the generated debris can fall onto the worktable 1. The above movement is repeated so that the cleaning rod 7 can clean the debris on the surface of the worktable 1 and let it fall into the collection box 19 through the trough 18.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
