Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a tooling and fixture for cylinder block machining. Background Technology
[0002] In the field of machining, cylinder blocks are key components of many mechanical devices, requiring extremely high machining precision. Traditional cylinder block machining fixtures often have many shortcomings, such as: clamping methods are simplistic and unstable, fixing the cylinder block only from a single direction or a few points. During machining, factors such as cutting forces and vibrations can easily cause displacement of the cylinder block, leading to dimensional deviations and increased scrap rates. Furthermore, traditional fixtures are cumbersome and time-consuming to clamp cylinder blocks, reducing production efficiency and failing to meet the demands of modern large-scale production. Additionally, some fixtures lack effective guiding and buffering mechanisms, making cylinder block installation and positioning inaccurate and convenient, and easily causing scratches, bumps, and other damage to the cylinder block surface during clamping, affecting its appearance quality and internal performance. Therefore, there is an urgent need to develop a new, efficient, and precise cylinder block machining fixture. Utility Model Content

[0023] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.
[0024] In this invention, unless otherwise specified, all parts and percentages are by weight, and the equipment and raw materials used are commercially available or commonly used in the field. Unless otherwise specified, the methods in the following embodiments are conventional methods in the field. Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0025] Example 1:
[0026] like Figure 1 , 2 As shown in Figure 3, this utility model provides a technical solution: a tooling fixture for cylinder block machining, including a mounting platform 1, which is bolted to a machine tool. A first clamping assembly 2 and a second clamping assembly 3 are symmetrically arranged on the left and right sides of the upper surface of the mounting platform 1. The first clamping assembly 2 can clamp the middle of the left and right sides of the upper surface of the cylinder block structure 11, including a first telescopic member 12. The fixed end of the first telescopic member 12 is bolted to the upper surface of the mounting platform 1. The telescopic end of the first telescopic member 12 is rotatably connected to a first pressure rod 13 via a rotating shaft. The free end of the first pressure rod 13 faces the cylinder block structure 11. A first connecting rod 14 is rotatably connected to the main body of the first telescopic member 12 via a rotating shaft. The upper end of the first connecting rod 14 is rotatably connected to the middle of the first pressure rod 13, forming a four-bar linkage. When the first telescopic member 12 extends or retracts, the first pressure rod 13 rotates around the rotating shaft through the linkage of the first connecting rod 14, realizing the clamping of the middle of the left and right sides of the upper surface of the cylinder block. By using clamping, this structure combining a connecting rod and a pressure rod can convert the linear motion of the telescopic component into the rotational clamping action of the pressure rod, enhancing the stability of the clamping force and adapting to the clamping requirements of cylinders of different sizes. The aforementioned second clamping assembly 3 can clamp the left and right ends of the rear side of the upper surface of the cylinder structure 11. The second clamping assembly 3 includes a second telescopic component 15. The fixed end of the second telescopic component 15 is fixedly connected to the upper surface of the mounting platform 1 by bolts. The telescopic end of the second telescopic component 15 is rotatably connected to a second pressure rod 16 via a rotating shaft. The free end of the second pressure rod 16 faces the cylinder structure 11. The main body of the second telescopic component 15 is rotatably connected to a second connecting rod 17 via a rotating shaft. The upper end of the second connecting rod 17 is rotatably connected to the middle part of the second pressure rod 16. Similar to the first clamping assembly 2, the second clamping assembly 3 provides auxiliary clamping from the left and right ends of the rear side of the upper surface of the cylinder, forming an all-round clamping system with the first clamping assembly 2, further stabilizing the position of the cylinder on the fixture and preventing displacement during processing.
[0027] Specifically, guide components 4 are symmetrically arranged between the two first clamping components 2, and a base 5 that can move up and down is arranged between the two guide components 4. A limit block 6 is installed on the rear side of the upper surface of the mounting platform 1. A drive component 7 connected to the base 5 is installed on the limit block 6. The drive component 7 can drive the base 5 to move upward. When the drive component 7 drives the base 5 to move upward, it can cooperate with the first clamping components 2 and the second clamping components 3 to clamp and limit the upper and lower surfaces of the cylinder structure 11. A first slide rail 8 is provided on the upper surface of the base 5, and a second slide rail 10 is provided on the front side of the mounting platform 1 through a support plate 9. When the cylinder structure 11 needs to be processed, the cylinder structure 11 is placed on the second slide rail 10, and the cylinder structure 11 is pushed manually. Under the guiding action of the guide components 4, the cylinder structure 11 smoothly enters the base 5. Both the second slide rail 10 and the first slide rail 8 play a supporting role.
[0028] Example 2:
[0029] like Figure 1 , 2 As shown in Figure 3, this utility model provides another technical solution, a tooling fixture for cylinder block processing. The difference from Embodiment 1 is that the lower part of the free ends of the first pressure rod 13 and the second pressure rod 16 are both bonded with a rubber buffer layer. During the clamping process of the cylinder block, the buffer layer can effectively avoid scratches and bumps caused by hard contact between the pressure rod and the cylinder block, protect the surface quality of the cylinder block, and ensure the integrity of the cylinder block appearance. This is especially important for some high-precision cylinder block processing with strict surface quality requirements.
[0030] Example 3:
[0031] like Figure 1 , 2 As shown in Figure 3, this utility model provides another technical solution: a tooling fixture for cylinder block machining. The difference from embodiment 1 is that the guide assembly 4 includes a first support column 18 arranged front and rear and a guide plate 19 connected between the two first support columns 18. The bottom of the first support column 18 is bolted to the upper surface of the mounting platform 1. The guide plate 19 is bolted to the side wall of the first support column 18. The inner front end of the guide plate 19 is provided with an inclined guide surface 20. When installing the cylinder block, the inclined guide surface 20 plays a guiding role, which makes it easy for the cylinder block to slide into the predetermined position quickly and accurately, reducing manual adjustment time and improving clamping speed.
[0032] Example 4:
[0033] like Figure 4As shown, this utility model provides another technical solution, a tooling fixture for cylinder block processing. The difference from embodiment 1 is that the interior of the aforementioned limiting block 6 is hollow, and the driving assembly 7 includes a third telescopic member 21, a third connecting rod 22, a first support seat 23, and a second support seat 24. The fixed end of the third telescopic member 21 is bolted to the top of the limiting block 6, and the telescopic end of the third telescopic member 21 abuts against the upper surface of the rear end of the third connecting rod 22. The first support seat 23 is bolted to the mounting platform 1, and the middle part of the third connecting rod 22 is rotatably connected to the first support seat 23 via a rotating shaft. The other end of the third connecting rod 22 is rotatably connected to the second support seat 24 via a rotating shaft, and the second support seat 24 is bolted to the lower surface of the base 5. A lever structure is used to raise the base 5, which, in conjunction with the first clamping assembly 2 and the second clamping assembly 3, achieves omnidirectional stable clamping of the cylinder block.
[0034] Specifically, the front side of the limiting block 6 is provided with a buffer pad 25. The buffer pad 25 can prevent the cylinder structure 11 from colliding hard with the limiting block 6, protect the cylinder structure 11 and the fixture components, reduce equipment wear, and extend the service life of the tooling fixture. The buffer pad 25 can also abut against the rear side of the cylinder structure 11 to play a supporting and limiting role.
[0035] Specifically, the upper surface of the mounting platform 1 is bolted with two second support columns 28 on the left and right. When the lower surface of the base 5 contacts the upper surface of the second support column 28, the first slide rail 8 and the second slide rail 10 are flush, and the cylinder can smoothly transition to the base 5, ensuring processing continuity and improving production efficiency.
[0036] Specifically, the base 5 has two through slots 26 on the left and right. The upper surface of the mounting platform 1 is bolted with guide posts 27, and the base 5 can move up and down along the guide posts 27 through the through slots 26. The front and rear sides of the guide posts 27 are in contact with the front and rear inner walls of the through slots 26. The guide posts 27 and the through slots 26 cooperate to provide precise guidance for the lifting and lowering of the base 5 and improve the processing accuracy.
[0037] like Figure 5As shown, in the initial clamping stage of the cylinder body, the cylinder body is moved to the second slide rail 10 of the tooling fixture, close to the guide assembly 4. Due to the design of the inclined guide surface 20 of the guide plate 19, the two sides of the cylinder body slide backward along the inclined guide surface 20. Under the action of manual reasoning, the cylinder body gradually moves to the top of the first slide rail 8 until the rear side of the cylinder body contacts the buffer pad 25, and the initial positioning is completed. The first telescopic component 12, the second telescopic component 15 and the third telescopic component 21 are started simultaneously. The first telescopic component 12 extends and pushes the first pressure rod 13 to rotate around the pivot. Through the linkage of the first connecting rod 14, the free end of the first pressure rod 13 is pressed tightly against the middle of the left and right sides of the upper surface of the cylinder body. Similarly, the second telescopic component 15 moves and drives the second pressure rod 16 to clamp the left and right ends of the rear side of the upper surface of the cylinder body. The third telescopic component 21 extends and presses down the third connecting rod 22, so that the base 5 moves up, and the initial clamping is completed.
[0038] This utility model provides a tooling fixture for cylinder block machining, which realizes stable clamping, precise positioning and efficient machining of cylinder blocks, improves machining accuracy and production efficiency, and reduces labor intensity and production costs. It has high practical value and promotion value.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
