Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a storage rack for machining magnesium alloy engine cylinder blocks. Background Technology

[0002] In the process of the automotive industry's transformation towards lightweighting and energy conservation, magnesium alloys have become an ideal material in the field of engine block manufacturing due to their outstanding advantages such as low density, high specific strength, excellent shock absorption, and good recyclability. Magnesium alloy engine blocks can not only significantly reduce the weight of the vehicle and improve power transmission efficiency, but also reduce fuel consumption and exhaust emissions, which is in line with the global automotive industry's "carbon neutrality" development goal. Therefore, the demand for their application in high-end new energy vehicles, high-performance fuel vehicles, and other fields continues to grow.

[0003] However, the fixed bracket made of welded steel pipe can only achieve simple stacking or flat placement of cylinders, lacking targeted positioning and buffering structures. Hard contact between the cylinder and the bracket can easily cause scratches on the flange surface. In addition, the cylinder is subjected to uneven force when stacked, which may cause slight deformation and damage the processing accuracy if stored for a long time. At the same time, the bracket has no sealed protection design, and the cylinder is completely exposed to the workshop air, resulting in a very high risk of oxidation and corrosion. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a storage rack for machining magnesium alloy engine cylinder blocks, so as to solve the problems of overall cylinder block structural deformation and oxidation prevention.

[0005] Based on the above objectives, this utility model provides a storage rack for machining magnesium alloy engine cylinder blocks, comprising: a storage rack, on which a first sliding plate is slidably mounted, and on which a second sliding plate is slidably mounted on the storage rack on the side corresponding to the first sliding plate, a first rear cover is fixedly mounted on the first sliding plate, and a first sealing box is fixedly connected to one side of the first rear cover. A plurality of evenly distributed first sliding rods are slidably mounted inside the first sealing box, and a first spring is fixedly mounted at one end of each first sliding rod, with the other end of the first spring fitting against the inside of the first rear cover.

[0006] A second sealing box is attached to the end of the first sealing box away from the first rear cover. A plurality of evenly distributed second sliding rods are slidably installed inside the second sealing box. A second spring is fixedly installed at one end of each second sliding rod. The end of the second spring away from the second sliding rod is attached to the second rear cover. The second rear cover is fixedly installed on the second sealing box.

[0007] As an optional implementation, a first rack is fixedly installed at the bottom end of the first sliding plate, a gear is meshed on the first rack, and a second rack is meshed on the side of the gear corresponding to the first rack, and the second rack is fixedly installed at the bottom end of the second sliding plate.

[0008] As an optional implementation, the gear is fixedly mounted on the servo motor drive end, and the servo motor is fixedly mounted on the storage rack.

[0009] As an optional implementation, cylinders are fixedly mounted on both sides of the servo motor, and a workpiece placement plate is fixedly mounted on the cylinder drive end.

[0010] As an optional implementation, the workpiece placement plate is located between the first sliding plate and the second sliding plate.

[0011] As an optional implementation, a vacuum pump is fixedly installed on the second sealed housing, a connecting pipe is fixedly connected to the drive end of the vacuum pump, the end of the connecting pipe away from the vacuum pump is fixedly installed on the second sealed housing, a pressure relief valve is fixedly installed on the connecting pipe, and a pressure gauge is fixedly installed on the second sealed housing on one side of the connecting pipe.

[0012] As an optional implementation, a shelf connecting seat is fixedly installed at both ends of the upper part of the storage shelf.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, after sealing the housing, the first sliding rod and the second sliding rod are evenly distributed inside the housing. When they come into contact with the cylinder, they form a multi-point fixation. Whether it is a regular cylindrical cylinder or an irregularly shaped cylinder with protrusions and depressions, the extension length of the first sliding rod and the second sliding rod can be automatically adjusted by the spring force. The sliding rod is compressed and retracted when the protruding part of the cylinder is pressed, and the sliding rod automatically extends to fill the space when the part is recessed. The stress is dispersed at multiple points, protecting the precision of the magnesium alloy cylinder and automatically fitting the irregular contour. No special clamps are required, making it suitable for storage scenarios of magnesium alloy engine cylinders of various specifications and high precision. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-4As shown, a storage rack for machining magnesium alloy engine cylinder blocks includes: a storage rack 1, a first sliding plate 3 slidably mounted on the storage rack 1, a second sliding plate 4 slidably mounted on the storage rack 1 on the side corresponding to the first sliding plate 3, a first rear cover 7 fixedly mounted on the first sliding plate 3, a first sealing box 8 fixedly connected to one side of the first rear cover 7, a plurality of evenly distributed first sliding rods 5 slidably mounted inside the first sealing box 8, a first spring 6 fixedly mounted at one end of the first sliding rod 5, and the other end of the first spring 6 fitting against the inside of the first rear cover 7;

[0025] The first sealing box 8 is connected to the second sealing box 12 at the end away from the first rear cover 7. Several evenly distributed second sliding rods 11 are slidably installed inside the second sealing box 12. A second spring 10 is fixedly installed at one end of the second sliding rod 11. The end of the second spring 10 away from the second sliding rod 11 is attached to the second rear cover 9. The second rear cover 9 is fixedly installed on the second sealing box 12.

[0026] Thus, the first sealing box 8 and the second sealing box 12 form a closed space after being fitted together, completely enclosing the cylinder block and effectively isolating it from the intrusion of external dust and debris. Inside the sealed box, the first sliding rod 5 and the second sliding rod 11 are evenly distributed inside the box, forming multi-point fixation when in contact with the cylinder block. Whether it is a regular cylindrical cylinder block or an irregularly shaped cylinder block with protrusions and depressions, the extension length of the first sliding rod 5 and the second sliding rod 11 can be automatically adjusted by the spring force. The protruding parts of the cylinder block compress the sliding rod to shrink, and the sliding rod automatically extends to fill the space in the recessed parts, dispersing stress at multiple points, protecting the precision of the magnesium alloy cylinder block, automatically fitting the irregular contour, and eliminating the need for customized special clamps. This is suitable for storage scenarios of magnesium alloy engine cylinder blocks of various specifications and high precision.

[0027] like Figures 1-4 As shown, a first rack 14 is fixedly installed at the bottom of the first sliding plate 3, and a gear 17 is meshed on the first rack 14. A second rack 16 is meshed on the side of the gear 17 corresponding to the first rack 14. The second rack 16 is fixedly installed at the bottom of the second sliding plate 4. The gear 17 is fixedly installed at the drive end of the servo motor 15, and the servo motor 15 is fixedly installed on the storage rack 1. Cylinders 18 are fixedly installed on both sides of the servo motor 15, and a workpiece placement plate 13 is fixedly installed at the drive end of the cylinders 18. The workpiece placement plate 13 is located between the first sliding plate 3 and the second sliding plate 4.

[0028] Thus, the cylinder is placed on the workpiece placement plate 13, and the cylinder is pushed to the same horizontal line as the first sealing box 8 by the cylinder 18. The servo motor 15 rotates clockwise, driving the gear 17 to rotate. The gear 17 drives the first rack 14, which is fixed to the first sliding plate 3, to move to the left. At the same time, it drives the second rack 16, which is fixed to the second sliding plate 4, to move to the right, so that the two sliding plates move in opposite directions synchronously. The first sealing box 8 and the second sealing box 12 are completely in contact. The sliding rod automatically adapts to the contour of the cylinder by the spring force, completing the automatic sealing and fixing of the cylinder.

[0029] like Figures 1-4 As shown, a vacuum pump 20 is fixedly installed on the second sealed housing 12. A connecting pipe 19 is fixedly connected to the drive end of the vacuum pump 20. The end of the connecting pipe 19 away from the vacuum pump 20 is fixedly installed on the second sealed housing 12. A pressure relief valve 22 is fixedly installed on the connecting pipe 19. A pressure gauge 21 is fixedly installed on the second sealed housing 12 on one side of the connecting pipe 19.

[0030] In this way, the vacuum pump 20 can adjust the internal pressure of the sealing box according to the different thickness requirements of the cylinder, realize precise pressure management, ensure that cylinders of different specifications are in the best protection environment, and flexibly adjust the internal pressure parameters. It can meet diverse production scenarios without replacing the equipment, thus improving the versatility of the equipment.

[0031] like Figure 1 As shown, storage rack 1 has storage rack connecting seats 2 fixedly installed at both ends above it.

[0032] Thus, the new design of the rack connecting seat 2 upgrades the magnesium alloy engine block storage rack from a single storage unit to an expandable three-dimensional storage system, improving space utilization.

[0033] Thus, in this embodiment, as... Figures 1-4As shown, the cylinder is placed on the workpiece placement plate 13, and the cylinder is pushed to the same horizontal line as the first sealing box 8 by the cylinder 18. The servo motor 15 rotates clockwise, driving the gear 17 to rotate. The gear 17 drives the first rack 14, which is fixed to the first sliding plate 3, to move to the left, and at the same time drives the second rack 16, which is fixed to the second sliding plate 4, to move to the right, realizing the "synchronous reverse movement" of the two sliding plates. The first sealing box 8 and the second sealing box 12 are completely fitted together. The sliding rod automatically adapts to the contour of the cylinder through the spring force, completing the automatic sealing and fixing of the cylinder. After the first sealing box 8 and the second sealing box 12 are fitted together, a closed space is formed, which completely encloses the cylinder and can effectively isolate the intrusion of external dust and debris. Inside the sealed box, the first sliding rod 5 and the second sliding rod 11 are evenly distributed inside the box, forming multi-point fixation when in contact with the cylinder, regardless of whether it is a regular cylindrical shape. The cylinder block, whether it's a protruding or recessed irregularly shaped cylinder block, allows the first sliding rod 5 and the second sliding rod 11 to automatically adjust their extension length via spring force. The protruding parts of the cylinder block compress the sliding rods, causing them to contract, while the recessed parts automatically extend to fill the space, thus dispersing stress at multiple points and protecting the precision of the magnesium alloy cylinder block. It automatically conforms to irregular contours, eliminating the need for custom-made fixtures and making it suitable for storing magnesium alloy engine cylinder blocks of various specifications and high precision. The upper vacuum pump 20 can adjust the internal pressure of the sealed box according to the different thickness requirements of the cylinder block, achieving refined pressure management and ensuring that cylinder blocks of different specifications are in the best protective environment. The internal pressure parameters can be flexibly adjusted, meeting diverse production scenarios without equipment replacement, thus improving equipment versatility. Furthermore, the newly designed rack connecting seat 2 upgrades the magnesium alloy engine cylinder block storage rack from a single storage unit to an expandable three-dimensional storage system, improving space utilization.
