[0002] In cylinder block machining production, the cylinder block tightening machine is the core equipment to ensure the accuracy of bolt assembly. The rationality of its mechanical structure directly determines the positioning accuracy, machine compatibility and operation efficiency.

[0003] However, existing cylinder tightening machines still have certain problems: The tightening process of existing cylinder tightening machines mostly relies on manual labor. Manual operation is labor-intensive, requiring repeated use of torque wrenches, resulting in high workload. In addition, manual loading, unloading, and positioning processes are time-consuming, leading to long single-operation times and low production efficiency. Therefore, we propose an automated, rapid positioning cylinder tightening machine to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide an automated and rapid positioning cylinder tightening machine to solve the problems mentioned in the background art, where the tightening process of the cylinder tightening machine is mostly done manually, the manual operation is labor-intensive, requires repeated use of torque wrenches, has a high workload, and the manual loading, unloading and positioning process is time-consuming, resulting in long single operation time and low production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated and rapid positioning cylinder tightening machine, comprising a base and a fixing frame. Two sets of fixing frames are symmetrically welded to the top of the base. Several conveying rollers are rotatably connected to the middle of the two sets of fixing frames. Several sprockets are rotatably connected to the outer side of the fixing frames, and one end of each sprocket is fixedly connected to the outer end of the conveying roller. The sprockets and conveying rollers are designed in a one-to-one correspondence. A chain is meshed with the outer surface of each sprocket. Two sets of supports are symmetrically welded to the top of the fixing frame. A pressure block is fixed to the inner side of each support. A third cylinder is bolted to the bottom of the base, and the extended end of the third cylinder passes through the middle of the base and extends to the top of the base. A positioning plate is fixed to the extended end of the third cylinder. Four sets of positioning pins are engaged with the upper surface of the positioning plate, and the four sets of positioning pins are evenly distributed along the four corners of the positioning plate.

[0006] Using the above technical solution, the extended end of the third cylinder at the bottom of the base pushes the positioning plate upward, and the four evenly distributed positioning pins on the positioning plate can perform preliminary positioning of the cylinder body; at the same time, the sprocket on the outside of the fixed frame is driven by a motor and cooperates with the chain drive to drive the conveying roller to rotate to transport the cylinder body, and the pressure block on the inside of the bracket assists in fixing the position of the cylinder body, realizing the automated transport and rapid and accurate positioning of the cylinder body, so as to facilitate subsequent tightening operations, improve production efficiency and reduce labor intensity.

[0007] Preferably, the upper end face of the positioning plate is provided with a plurality of positioning holes that are adapted to the positioning pins, and the surface of the positioning pins is coated with a wear-resistant coating.

[0008] By adopting the above technical solution, a number of positioning holes for matching positioning pins are evenly opened on the positioning plate, so that the positioning pins can be accurately inserted into the corresponding positioning holes according to the positioning requirements of different cylinder models, achieving flexible and accurate positioning adjustment; and the surface of the positioning pins is coated with a wear-resistant coating, which can effectively reduce friction and wear with the cylinder and other components during frequent positioning, extend the service life of the positioning pins, ensure the positioning accuracy and stability under long-term use, and thus improve the working reliability and production quality of the entire cylinder tightening machine.

[0009] Preferably, a back plate is welded to the upper surface of the base, a longitudinal groove is provided on one side of the back plate, a first cylinder is bolted to the top of the back plate, a support platform is provided on one side of the back plate, and the extended end of the first cylinder is fixedly connected to the protrusion of the support platform.

[0010] Using the above technical solution, the back plate is welded to the base to provide stable support, and the longitudinally opened groove provides a sliding guide track for the support platform. When the first cylinder at the top is working, the extension end can extend and retract to drive the support platform fixedly connected to it to move longitudinally along the groove, thereby realizing the precise position adjustment of the support platform in the vertical direction, meeting the height requirements of the support platform when tightening cylinders of different heights, and enhancing the versatility and applicability of the equipment.

[0011] Preferably, the upper surface of the support platform is fixed with two sets of slide rails, and the slide rails are T-shaped. Two sets of slide tables are symmetrically installed above the support platform, and the slide tables are slidably connected to the slide rails. A second cylinder is installed at both ends of the support platform, and the extended end of the second cylinder is fixedly connected to the slide table. A tightening gun is installed on the upper surface of the slide table, and the output end of the tightening gun is connected to a tightening shaft through a custom connecting rod bolt.

[0012] By adopting the above technical solution, the T-shaped slide rail on the upper surface of the support platform provides a stable and precise sliding track for the slide table. The slide table is slidably connected to the slide rail, allowing the slide table to move flexibly in a predetermined direction. This allows the position of the tightening gun on the slide table to be flexibly adjusted according to the position of the bolts on different cylinders. The output end of the tightening gun is connected to the tightening shaft through a customized connecting rod, which can accurately transmit the power of the tightening gun to the tightening shaft, realizing the automated tightening operation of the cylinder bolts and improving the equipment's adaptability to cylinders of different specifications and the accuracy of the tightening operation.

[0013] Preferably, the tightening shaft is a twelve-angle short shaft bolt tightening head structure.

[0014] By adopting the above technical solution, a tightening shaft with a twelve-angle short-shaft pulsar tightening head structure is selected. Its twelve-angle design can better match the twelve-angle shape of the bolt head, achieving a more uniform force distribution during tightening, effectively reducing slippage, and improving the reliability and accuracy of tightening. The short-shaft structure makes the tightening shaft more compact, adapting to the relatively compact bolt layout space on the cylinder, facilitating operation in confined areas. The pulsar tightening head has high strength and good wear resistance, can withstand large tightening torque, and ensures stable performance during long-term, high-intensity tightening operations, thereby improving the quality and production efficiency of cylinder tightening.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The positioning plate is raised by the third cylinder at the bottom of the base. The positioning holes evenly distributed on the positioning plate, together with the positioning pins evenly distributed at the four corners and with wear-resistant coating, can flexibly adapt to different models of cylinders and achieve precise positioning, reduce positioning errors and component wear, extend the service life of the equipment, improve the automation, accuracy and stability of cylinder conveying, positioning and subsequent tightening operations, and effectively improve production efficiency and product quality. 2. The tightening shaft uses a twelve-angle short-shaft pulsar tightening head structure. Its twelve-angle design better matches the twelve-angle shape of the bolt head, achieving a more even force distribution during tightening, effectively reducing slippage and improving tightening reliability and accuracy. The short-shaft structure makes the tightening shaft more compact, adapting to the relatively tight bolt layout space on the cylinder, facilitating operation in confined areas. The pulsar tightening head has high strength and good wear resistance, can withstand large tightening torque, and ensures stable performance during long-term, high-intensity tightening operations, thereby improving the quality and production efficiency of cylinder tightening.

The upper surface of the positioning plate 18 is evenly provided with several positioning holes that are compatible with the positioning pins 19, and the surface of the positioning pins 19 is coated with a wear-resistant coating.

[0020] The base 1 serves as the basic support structure, with two sets of symmetrically welded fixing frames 11 on top for mounting other components. Several conveying rollers 12 are rotatably connected in the middle of the fixing frames 11, capable of carrying and conveying the cylinder body. Sprockets 13, corresponding one-to-one with the conveying rollers 12 and fixed at their outer ends, are rotatably connected on the outer sides. These sprockets 13 are driven by a motor and, through meshing with a chain 14, achieve synchronous rotation under the motor's power, thereby driving the conveying rollers 12 to complete the conveying of the cylinder body. Two sets of symmetrically welded brackets 15 on top of the fixing frames 11 have pressure blocks 16 fixed to their inner sides, which can be used to press the cylinder body into place after it has been conveyed.

Example 2

[0021] Please refer to Part Two Figure 2 , Figure 4 This utility model provides a technical solution: A back plate 2 is welded to the upper surface of the base 1. A longitudinal groove 3 is formed on one side of the back plate 2. A first cylinder 4 is bolted to the top of the back plate 2. A support platform 5 is provided on one side of the back plate 2, and the extended end of the first cylinder 4 is fixedly connected to the protrusion of the support platform 5. Two sets of slide rails 6 are fixed to the upper surface of the support platform 5. The slide rails 6 have a T-shaped structure. Two sets of slide tables 7 are symmetrically installed above the support platform 5, and the slide tables 7 are slidably connected to the slide rails 6. A second cylinder 8 is installed at both ends of the support platform 5, and the extended end of the second cylinder 8 is fixedly connected to the slide table 7. A tightening gun 9 is installed on the upper surface of the slide table 7. The output end of the tightening gun 9 is connected to a tightening shaft 10 by a custom connecting rod bolt. The tightening shaft 10 adopts a twelve-angle short shaft tightening head structure.

[0022] The back plate 2 welded to the upper surface of the base 1 provides stable support for the entire adjustment and tightening module. A longitudinally opened slide groove 3 on one side provides a guide rail for the movement of the support platform 5.

The tightening gun 9 installed on the upper end of the slide table 7 has a tightening shaft 10 connected to the output end by a customized connecting rod bolt. It adopts a twelve-angle short shaft bolt tightening head structure. The twelve-angle design makes the tightening shaft 10 fit more tightly with the bolt head, reducing slippage. The short shaft structure is convenient for operation in confined spaces. The bolt tightening head structure can withstand large torque, thereby achieving precise and reliable tightening of the cylinder body bolts.

[0023] Working principle: For this type of automated rapid positioning cylinder tightening machine, the cylinder is first placed on several conveying rollers 12 in the middle of the fixed frame 11 above the base 1. The motor drives the sprockets 13, which rotate synchronously through the chain 14, driving the conveying rollers 12 to transport the cylinder to the designated position. Next, the pressure block 16 on the inner side of the bracket 15 above the fixed frame 11 initially presses and fixes the cylinder. Subsequently, the extended end of the third cylinder 17 at the bottom of the base 1 pushes the positioning plate 18 upward. Depending on the cylinder model, the positioning pin 19 is inserted into the positioning plate. The positioning holes on the position plate 18 and the positioning pins 19 evenly distributed at the four corners precisely position the cylinder body; then, the first cylinder 4 at the top of the back plate 2 extends and retracts, driving the support platform 5 to move longitudinally along the slide groove 3 on one side of the back plate 2 to a suitable height; then, the slide table 7 above the support platform 5 slides along the slide rail 6 of the T-shaped structure and is adjusted to the horizontal position of the bolt on the cylinder body; finally, the tightening gun 9 on the upper end of the slide table 7 works, driving the tightening shaft 10, which uses a twelve-angle short shaft tightening head structure, to precisely and reliably tighten the cylinder body bolts through the customized connecting rod.
