Description

Technical Field

[0001] This utility model relates to a hydraulic cylinder mounting structure, specifically, to a hydraulic cylinder body shot peening split mounting protection device. Background Technology

[0002] When shot peening hydraulic cylinders, the mounting structure is an important auxiliary equipment required for automated shot peening production lines. However, the currently widely used mounting structures have significant drawbacks, severely restricting production line efficiency and shot peening quality. These drawbacks are as follows: First, they have poor versatility, making it impossible to quickly connect or disconnect hydraulic cylinders of different diameters and specifications; second, the internal clamping mounting structure requires clamping the inner wall of the hydraulic cylinder, which carries the risk of scratching the finished surface; third, they have complex structures, high maintenance costs, and a large overall weight, increasing the difficulty of handling and mounting, increasing the burden on the overall drive system, and making them inconvenient for production use.

[0003] For example, Chinese invention patent CN202311286861.6 discloses a hydraulic cylinder surface shot blasting and drying system. This system uses a positioning roller 309 whose circumferential sidewall abuts against the inner wall of the hydraulic cylinder body to load the cylinder body onto a lifting mechanism 3. Then, when the gear 701 meshes with the rack 7, the pulley 201 reciprocates, causing the gear 701 to roll on the rack 7. This, in turn, allows the lifting mechanism 3 to rotate the hydraulic cylinder body, effectively ensuring the processing efficiency and effect of the hydraulic cylinder body. While this disclosure has good versatility, the positioning roller 309 abuts against the inner wall of the cylinder, posing a risk of scratching the finished surface. Furthermore, the overall structure is complex and heavy.

[0004] For example, Chinese invention patent CN202311381300.4 discloses a lifting device for shot blasting hydraulic cylinders, including a track and a hanger. It is configured with an inner rod, an outer cylinder, and a carrying frame. Multiple support rods on the carrying frame have limit sleeves, and each limit sleeve can be fitted with a cylinder. When the outer cylinder rotates, a first bevel gear drives a second bevel gear to rotate, causing the limit sleeves to flip. The limit sleeves continuously rotate the cylinders, changing the angle and position of the shot blasting nozzle between the cylinder and the cylinder, allowing both the inner and outer surfaces of the cylinder to be polished. Although this disclosure eliminates the need to clamp the inner wall of the hydraulic cylinder, clamping the outer wall results in a portion of the outer wall remaining unblasted, and the overall structure is complex and heavy.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a split-type shot peening protection device for hydraulic cylinder bodies. This device has good versatility, facilitates quick and easy connection of hydraulic cylinder bodies, avoids connection through the inner and outer walls of the hydraulic cylinder, and features a simple overall structure and light weight.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a lifting shaft and a threaded connecting plate. The bottom end of the lifting shaft is provided with a first hanging mechanism, and the threaded connecting plate is provided with a second hanging mechanism. The lifting shaft connects the threaded connecting plate by connecting the first hanging mechanism and the second hanging mechanism. The threaded connecting plate is provided with an external thread for connecting the internal thread of the cylinder bore.

[0008] Based on the above, the threaded connection disc is provided with a protective pad to prevent the cylinder opening from being affected by shot peening.

[0009] Based on the above, the protective pad is disposed on the hanging shaft, the hanging shaft is provided with an elastic element, the protective pad is a rigid protective pad, when the first hanging mechanism and the second hanging mechanism are connected, the protective pad on the hanging shaft is affected by the elastic force of the elastic element and tends to stick to the threaded connecting disc.

[0010] Based on the above, the diameter of the protective pad is larger than the diameter of the threaded connecting disc, and the protective pad covers the threaded connecting disc, the first hanging mechanism, and the second hanging mechanism.

[0011] Based on the above, the first suspension mechanism and the second suspension mechanism are connected by a bayonet connection.

[0012] Based on the above, the first hanging mechanism adopts a rotary locking tongue, and the second hanging mechanism adopts a buckle plate that can be inserted into the rotary locking tongue.

[0013] Based on the above, the end of the rotating latch away from the hanging shaft is provided with a latch lug to form a latch hook. The latch hook can be engaged with the buckle plate so that the hanging shaft can suspend the buckle plate and radially lock the two together.

[0014] Based on the above, the buckle plate is a long strip plate, and the buckle plate is provided with a lock opening in the same direction as the length of the buckle plate. After the two oppositely arranged lock tongue hooks are inserted into the lock opening and rotated 90°, the parts of the buckle plate on both sides of the lock opening can be respectively embedded into the two lock tongue hooks.

[0015] Based on the above, the threaded connecting disc includes a threaded ring and a buckle plate, with both ends of the buckle plate connected to the threaded ring.

[0016] Based on the above, the hanging shaft is provided with an adjustment base, and the two ends of the elastic element abut against the protective pad and the adjustment base respectively. The adjustment base can be adjusted to the position on the hanging shaft.

[0017] This utility model has substantial features and advancements compared to existing technologies. Specifically, this device, by setting threaded connecting discs of different diameters and external threads of different specifications, and by setting a lifting shaft of the same specification, a first hanging mechanism, and a second hanging mechanism, can quickly connect or disconnect hydraulic cylinder bodies of different diameters and specifications, exhibiting good versatility. The external thread of the threaded connecting disc connects to the internal thread of the hydraulic cylinder body, eliminating the need to clamp the inner or outer cylinder wall, thus avoiding obstruction of shot peening operations on the outer cylinder wall and preventing scratches on the finished surface of the inner cylinder wall. The overall structure is simple and lightweight, facilitating maintenance and transportation, and is beneficial for production use.

[0018] Meanwhile, this device uses a protective pad to prevent the shot blasting medium from entering the hydraulic cylinder body from the cylinder port during shot blasting, which helps to further reduce the weight of the threaded connecting plate. Placing the protective pad on the lifting shaft and using an elastic element to hold it against the threaded connecting plate facilitates the overall assembly and disassembly process. The snap-fit ​​connection between the first and second lifting mechanisms allows for quick assembly and disassembly. Setting the first lifting mechanism as a locking hook and the second lifting mechanism as a snap-on plate allows the lifting shaft to be radially locked to the snap-on plate, while also reducing the overall weight.

[0022] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0023] Example 1

[0024] like Figure 1 , Figure 2As shown, the hydraulic cylinder body shot peening split-type hanging protection device of this embodiment includes a lifting shaft 1 and a threaded connecting plate 2. The upper end of the lifting shaft 1 is used to connect to the transport line of the cylinder body shot peening production line. For example, the top end of the lifting shaft 1 is provided with a hook 14 for connecting to the transport track. The bottom end of the lifting shaft 1 is provided with a first hanging mechanism 11, and the threaded connecting plate 2 is provided with a second hanging mechanism 21. After the first hanging mechanism 11 and the second hanging mechanism 21 are connected, the lifting shaft 1 can be connected to the threaded connecting plate 2 through the first hanging mechanism 11 and the second hanging mechanism 21. The threaded connecting plate 2 is provided with an external thread 22 for connecting the internal thread of the cylinder body. By setting different diameters of the threaded connecting plate 2 and different specifications of external threads 22, and setting different specifications of threaded connecting plates 2 as a second hanging mechanism 21 with a uniform specification, it is possible to quickly connect hydraulic cylinder bodies of different diameters and specifications to the lifting shaft 1, thereby realizing the rapid access or removal of hydraulic cylinder bodies on the cylinder body shot peening production line.

[0025] Specifically, in use, the threaded connecting disc 2 is connected to the cylinder port of the hydraulic cylinder body via a threaded connection, and then the first hanging mechanism 11 and the second hanging mechanism 21 are connected to complete the connection between the lifting shaft 1 and the threaded connecting disc 2, which in turn completes the connection between the lifting shaft 1 and the hydraulic cylinder body; when it is necessary to remove it, the operation is reversed.

[0026] In this embodiment, by setting threaded connecting discs 2 of different diameters and external threads 22 of different specifications, and by setting lifting shafts 1, first hanging mechanism 11 and second hanging mechanism 21 of the same specifications, it is possible to quickly connect or disconnect hydraulic cylinder bodies of different diameters and specifications, which has good versatility. The external thread of the threaded connecting disc 2 is connected to the internal thread of the hydraulic cylinder body, which eliminates the need to clamp the inner or outer cylinder wall of the hydraulic cylinder, thus avoiding obstruction of shot peening operations on the outer cylinder wall and avoiding scratching the finishing surface of the inner cylinder wall. The overall structure is simple and lightweight, which is convenient for maintenance and transportation and is beneficial for production use.

[0027] Example 2

[0028] Based on Example 1, such as Figure 1 As shown, the threaded connecting disc 2 is provided with a protective pad 3 to prevent the cylinder orifice from being affected by shot peening. The protective pad 3 prevents the shot peening medium (or shot peening abrasive) from entering the hydraulic cylinder body from the cylinder orifice during shot peening operations, thus preventing wear on the finished surface of the inner wall. Furthermore, by using the protective pad 3, the threaded connecting disc 2 can be made hollow, which further reduces the overall weight of the threaded connecting disc 2. In other embodiments, the threaded connecting disc 2 itself can be used as a protective pad to prevent shot peening abrasive from entering the hydraulic cylinder body.

[0029] Furthermore, the protective pad 3 is inserted through the lifting shaft 1 and positioned above the first hanging mechanism 11. The lifting shaft 1 is equipped with an elastic element 12 (such as a spring or elastic cylinder). The protective pad 3 is made of rigid material. When the first hanging mechanism 11 and the second hanging mechanism 21 are connected, the protective pad 3, under the influence of the elastic force of the elastic element 12 on the lifting shaft 1, tends to adhere tightly to the threaded connecting disc 2. The protective pad 3 and the threaded connecting disc 2 are designed as separate units, so the protective pad 3 will not obstruct the connection process between the threaded connecting disc 2 and the hydraulic cylinder body, facilitating the rapid connection of the threaded connecting disc 2 to the hydraulic cylinder body. The protective pad 3 can be made of materials such as leather. In other embodiments, the protective pad 3 can also be a soft or hard protective pad fixed to the threaded connecting disc 2 (e.g., by adhesive bonding, bolting, etc.).

[0030] Furthermore, the diameter of the protective pad 3 is larger than the diameter of the threaded connecting disc 2. The protective pad 3 covers the threaded connecting disc 2, the first hanging mechanism 11, and the second hanging mechanism 21 to prevent shot peening medium or other substances from entering from the connection between the first hanging mechanism 11 and the second hanging mechanism 21.

[0031] Based on the above, the hanging shaft 1 is provided with an adjustment base 13, and the two ends of the elastic element 12 abut against the protective pad 3 and the adjustment base 13 respectively. The adjustment base 13 can be adjusted on the hanging shaft 1 to adjust the elastic force of the elastic element 12 (such as a spring).

[0032] In this embodiment, the protective pad 3 can prevent the shot blasting medium from entering the hydraulic cylinder body from the cylinder port during shot blasting, which is beneficial to further reduce the weight of the threaded connecting plate 2; placing the protective pad 3 on the lifting shaft 1 and using the elastic element 12 to press the protective pad 3 against the threaded connecting plate 2 is beneficial to the overall disassembly and assembly process of the device.

[0033] Example 3

[0034] Based on Example 2, such as Figure 1 , Figure 2 As shown, in this embodiment, the first hanging mechanism 11 and the second hanging mechanism 21 are connected by a bayonet connection, such as a rotary lock, which allows for quick assembly and disassembly. Simultaneously, because the elastic element 12 abuts against the protective pad 3, when the first hanging mechanism 11 and the second hanging mechanism 21 are connected, the elastic element 12 can also exert a spring force on the threaded connecting disc through the protective pad 3, which further facilitates the locking of the first hanging mechanism 11 and the second hanging mechanism 21 through the bayonet. In other embodiments, connection methods such as magnetic attraction, flange connection, or clamping can also be used to connect the two.

[0035] Specifically, the first hanging mechanism 11 adopts a rotary locking tongue 111, and the second hanging mechanism 21 adopts a buckle plate 211 into which the rotary locking tongue 111 can be inserted. The buckle plate 211 is provided with a slot for inserting the rotary locking tongue 111. After the rotary locking tongue 111 passes through the slot and is inserted into the buckle plate 211 and rotated, the threaded connecting plate 2 and the hydraulic cylinder body connected thereto can be hung by the rotary locking tongue 111 of the first hanging mechanism 11 by their own weight.

[0036] Furthermore, the end of the rotating locking tongue 111 away from the lifting shaft 1 is provided with a locking tongue lug 112 to form a locking tongue hook 113. The locking tongue hook 113 is inserted into the buckle plate 211 and rotated to engage with the buckle plate 211, so that the lifting shaft 1 can suspend the buckle plate 211 and lock the two radially, which is beneficial for stable shot peening operations.

[0037] Furthermore, the buckle plate 211 is a long strip plate with a straight locking slot 212 that is aligned with the length of the buckle plate 211. Two locking hooks 113 arranged in opposite directions at the bottom of the hanging shaft 1 are inserted into the locking slot 212 and rotated 90°. The parts of the buckle plate 211 on both sides of the locking slot 212 can be respectively embedded into the two locking hooks 113, which helps to further reduce the overall weight of the buckle plate 211. The locking hooks 113 are generally square in cross-section and right-angle hooks. The parts of the buckle plate 211 on both sides of the locking slot 212 are also square in cross-section. The parts of the buckle plate 211 on both sides of the locking slot 212 fit into the right-angle hooks, which can more stably perform radial locking.

[0038] Example 4

[0039] Based on Embodiment 2 or Embodiment 3, the threaded connecting disc 2 includes a threaded ring 23 and a buckle plate 211. Both ends of the buckle plate 211 are connected to the threaded ring 23. The external thread 22 is provided on the outer ring of the threaded ring 23. The buckle plate 211 is connected to the inner ring or bottom (end face) of the threaded ring 23. This achieves the purpose of hanging while making the threaded connecting disc 2 hollow, which is beneficial for weight reduction.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
