Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically a verticality detection device applicable to heavy-duty hydraulic cylinders. Background Technology

[0002] As the company's hydraulic cylinder products continue to upgrade, the weight and size of the hydraulic cylinders are constantly increasing, and the number of specifications and models is also increasing. This makes it more difficult for on-site workers to align the perpendicularity between the hydraulic cylinder and the lug during the welding process, especially for different product models. Since manual spot welding is performed before welding, the previous alignment method required manual use of a knife-edge right-angle ruler to align the perpendicularity between the hydraulic cylinder and the lug. Due to the weight of the hydraulic cylinder and its rotating nature, it is difficult to find the fulcrum of the rotating body. Therefore, after spot welding, the measurement is repeated, and if it is not up to standard, it needs to be broken open with a copper hammer for repeated confirmation. This increases the labor intensity of on-site workers and reduces product reliability. There is an urgent need to design a convenient and fast alignment method. The company uses a high-precision verticality testing device to meet the verticality alignment requirements between hydraulic cylinders and lugs for different product types. Summary of the Invention

The lifting device includes a connecting plate I9, a connecting plate II10, a lifting ring 11, and a reinforcing rib II12. The connecting plate I9 and the connecting plate II10 are vertically connected to form an L-shape. The reinforcing rib II12 is disposed between the connecting plate I9 and the connecting plate II10. The lifting ring 11 is disposed on the connecting plate I9. The connecting plate II10 is connected to the reinforcing rib I2. This utility model discloses a verticality testing device for heavy-duty hydraulic cylinders, comprising a measuring device and a hoisting device connected together. The measuring device includes a V-block, an I-plate, and a reinforcing rib I. The V-block and the I-plate are spliced ​​together to form an L-shaped verticality measuring main structure. A reinforcing rib is then installed in the right-angle area to enhance the structure's strength, rigidity, and stability, resisting bending and deformation. This also optimizes material usage, achieving a lightweight design, thus enabling the testing of hydraulic cylinders of different tonnages. Left and right guide rails are installed on the bottom side of the V-block. Meanwhile, guide rails are installed on the outer side of the Type I plate. The two guide rails are similar and are used to contact the workpiece being measured to achieve line contact measurement and improve measurement accuracy. The lifting device includes connecting plate I, connecting plate II, lifting ring, and reinforcing rib II. Connecting plate I and connecting plate II are spliced ​​to form an L-shaped structure. Reinforcing rib II is set between connecting plate I and connecting plate II, which ensures the rigidity of the lifting fixture to a certain extent. The connection between the measuring device and the lifting device is achieved by connecting plate II and reinforcing rib I. Connecting plate II and reinforcing rib I are connected together by bolt I, which facilitates disassembly and installation.

[0020] like Figures 1 to 2 The invention relates to a verticality testing device for heavy-duty hydraulic cylinders, wherein the V-block 1 and the I-plate 3 are connected together by bolt I 8. In this invention, the I-plate is connected to the V-block on one side by bolt I, which is an M10 bolt. Simultaneously, the V-block and the I-plate are also connected to the reinforcing rib I by bolt I, facilitating replacement of the I-plate after natural damage.

[0021] like Figure 1 The invention relates to a verticality testing device for heavy-duty hydraulic cylinders, wherein the reinforcing rib I2 has an adjustment accuracy of 0.5mm. The V-block mechanism and the I-plate of this invention are fixed together by reinforcing ribs, with an adjustment accuracy of 0.5mm on the ribs, to improve the accuracy of the verticality testing device and prevent deformation of the measuring device, thereby ensuring the reliability of product accuracy.

[0022] like Figures 1 to 2The invention discloses a verticality detection device for heavy-duty hydraulic cylinders.

In this invention, the left and right guide rails are installed on the bottom side of the V-block. The left and right guide rails are positioned by locating pins and connected by bolts II. Bolts II are countersunk M3 bolts. After installation, the plane of bolt II is lower than the plane of the guide rails. During installation, a dial indicator is used to measure and adjust the screw-in length of the M3 bolts to adjust the plane height of the left and right guide rails, achieving precision control of the left and right guide rails. This achieves the purpose of placing the hydraulic cylinder in a flat position. Simultaneously, the reference surfaces of the left and right guide rails are ground to improve surface roughness, which can prevent scratches and irreparable damage to the finished hydraulic cylinder body. A guide bar is installed on the outer side of the Type I plate. Similar to the two guide rails on the V-block, this guide bar is positioned using locating pins and connected by bolts II. A dial indicator is used to measure and adjust the screw-in distance of the M3 bolts, thereby achieving precision control of the guide bar. This prevents displacement errors during hydraulic cylinder testing, avoiding inaccurate measurements and the need for repeated spot welding of the hydraulic cylinder. Furthermore, the contact between the guide bar and guide rails and the contact surface, connected by bolts and locating pins, facilitates replacement of the guide bar and guide rails after natural damage, increasing the service life of the entire device.

[0023] like Figures 1 to 2 The device shown is a verticality testing device for heavy-duty hydraulic cylinders. The guide bar 4 has an arc-shaped surface that contacts the workpiece. The arc-shaped design of the guide bar measuring surface at the type I plate of this invention is more conducive to protecting the earring from damage, thereby improving the product's appearance quality. The arc surface achieves line contact, which is beneficial for operators to measure and observe. Combined with a 0.03mm feeler gauge, the hydraulic cylinder test results can be quickly confirmed.

[0024] like Figure 1 and Figure 3 The diagram illustrates a verticality testing device for heavy-duty hydraulic cylinders. Connecting plate I 9 and connecting plate II 10 are connected together by bolt I. Connecting plate I 9 has a lifting ring 11 and a slotted groove 14.
