Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically relating to a device for efficient processing of balance elbows in walking systems. Background Technology

[0002] The balance elbow is an important component of tracked vehicles, used to connect the vehicle body and the road wheels. It transfers the large amount of impact energy generated by the up-and-down movement of the road wheels to the torsion shaft, thereby reducing the impact force on the vehicle body. Since the balance shaft is a large component in the structure of tracked vehicles and is a cast product with many processing steps and large cutting volume, considering the actual production conditions, reducing the number of process steps can greatly improve the product processing efficiency and quality.

[0003] This product involves machining a balance elbow assembly and balance elbow shaft as a whole. The raw material for the machining area is a cast product with low surface roughness and large dimensional tolerances. The balance elbow shaft and the load wheel shaft have different lengths, as does the length of the intermediate balance elbow arm. The overall size, weight, and complex shape make it difficult to clamp. Currently, machining requires first marking and alignment before rough milling. Due to poor dimensional consistency, each part needs to have its clamping surface changed and aligned before finish milling, followed by changing equipment and re-clamping for drilling and reaming. Due to drawing requirements, drilling and tapping processes at other angles require further clamping. This method requires the operator to clamp and align four times, resulting in low efficiency, difficult lifting, and poor safety. Therefore, a rapid positioning process tool needs to be designed to improve clamping efficiency and simplify operation.

[0004] When machining the balance elbow, the balance elbow and the balance elbow shaft are machined together. The balance elbow shaft is a stepped cylinder and is located in the shaft hole at the right end of the balance elbow, which is called the balance elbow assembly. The middle section of the balance elbow shaft is a cylinder with a larger diameter, and the lower end is a cylinder with a smaller diameter.

[0005] Disadvantages of existing technical solutions:

[0006] For the machining of balance shafts, existing technical solutions require multiple clamping and alignment operations, making repeated positioning difficult and resulting in low clamping efficiency. They often require a significant amount of time and specialized instruments for measurement, leading to low machining efficiency. Utility Model Content

[0007] The technical problem to be solved by this utility model is:

[0008] To address the shortcomings of existing technologies, this utility model provides a device for the efficient machining of balance elbows in walking systems. It primarily employs a rapid positioning fixture, which significantly improves machining efficiency by increasing the workpiece positioning speed. This device completely solves the problem of machining and clamping balance elbow assemblies with irregular shapes and unstable centers of gravity. The design utilizes the principle of slotted base plates for stable clamping of parts, reducing labor intensity while increasing clamping efficiency. It features a simple structure, convenient operation, and suitability for various equipment machining environments.

[0009] This utility model discloses a high-efficiency processing device for a walking system balance elbow, including a base. The base has a positioning groove on the precision-machined circumference of the balance elbow shaft, which can accurately align and has the advantages of automatic alignment and multi-process processing in one clamping. It solves the problem of fixing the balance elbow to the processing platform with bolts and clamps. This method only requires the operator to use lifting equipment to lift the part onto the tooling, tighten the bolts on the part, and complete the clamping.

[0010] The technical solution of this utility model is:

[0011] A device for efficient machining of balance elbows in walking systems, characterized in that it includes a base plate, a pressure plate, support bolts, and U-shaped washers;

[0012] The base plate is used to support the parts; the parts are balance shaft assemblies; the balance shaft assembly includes a horizontal balance elbow and a vertically placed balance elbow shaft;

[0013] The base plate is provided with a positioning groove, which is located on the far right side of the base plate. The positioning groove is a through groove at both the top and bottom, and is a semi-open groove that opens to the right and has a semi-circular arc shape on the left. The left side of the positioning groove is connected to the base plate.

[0014] The larger diameter cylinder in the middle section of the balance elbow shaft is located in the positioning groove, that is, the lower part of the outer periphery of the larger diameter cylinder in the middle section of the balance elbow shaft is close to the cylindrical surface in the vertical direction corresponding to the left semi-circular arc of the positioning groove; the U-shaped pad is supported between the base plate and the lower end face of the balance elbow, and the U-shaped pad is located on the outer periphery of the larger diameter cylinder in the middle section of the balance elbow shaft.

[0015] The lower end of the base plate is connected to the support bolt, and the upper end of the support bolt is used to support the lower end face of the balance elbow, located on the lower left side of the balance elbow.

[0016] The pressure plate is located at the upper end of the balance elbow, pressing the balance elbow. The pressure bolt passes through the pressure plate, and the lower end of the pressure bolt is connected to the base plate.

[0017] Furthermore, the contour shape of the U-shaped gasket is consistent with the contour shape of the positioning groove.

[0018] Furthermore, the radius of the semicircular arc of the positioning groove is the same as the radius of the larger cylinder of the balance elbow shaft.

[0019] Furthermore, the positioning groove is a U-shaped groove.

[0020] Furthermore, the length of the positioning groove in the left-right direction is greater than the diameter of the larger cylinder of the balance elbow shaft.

[0021] Furthermore, the U-shaped gasket has the same outline shape as the positioning groove, and the diameter of the semicircular arc of the U-shaped gasket is larger than the diameter of the semicircular arc of the positioning groove, which is used to make way for the boss at the corresponding position of the balancing elbow shaft.

[0022] Furthermore, the pressure plates are two plates symmetrically distributed front and back.

[0023] The specific structural design of this utility model aims to provide a technical solution that, based on a simple structure, can limit the angle or orientation of an object placed on a base plate.

[0024] Specifically, the upper surface of the positioning groove serves as the direct support surface on the base plate for supporting the part. The width of the positioning groove restricts the part's placement, ensuring it can only be inserted into the groove from its opening side at a specific angle or orientation, thus supporting it on the base plate. This allows the part to be clamped between the positioning groove and the base plate, achieving accurate positioning of the part on the base plate. The arc diameter and width of the positioning groove are set to match the bottom dimensions of the clamped part.

[0025] As described above, the tooling provided in this solution can quickly position parts on the base plate. Furthermore, this tooling features a simple structure.

[0026] Further technical solution: In order to make the device applicable to the processing of balance elbows of various vehicle models, the support bolts can be replaced with different lengths, and the clamping plate can be replaced according to the external dimensions of the parts.

[0039] When machining the balance elbow of the walking system, the balance elbow and the balance elbow shaft are machined together. The balance elbow shaft is a stepped cylinder and is located in the shaft hole at the right end of the balance elbow, which is called the balance elbow assembly. The middle section of the balance elbow shaft is a cylinder with a larger diameter, and the lower end is a cylinder with a smaller diameter.

[0040] This utility model discloses a device for efficient processing of balance elbows in walking systems, which consists of a base plate 1, a positioning groove 2, a pressure plate 3, a support bolt 4, and a U-shaped washer 5.

[0041] The base plate is used to support components (balance elbow assembly);

[0042] The base plate is provided with a positioning groove, which is located on the far right side of the base plate. The positioning groove is a through groove at both the top and bottom, and is a semi-open groove that opens to the right. The left side is a semi-circular arc shape (i.e., a U-shaped through groove that opens to the right). The left side of the positioning groove is connected to the base plate.

[0043] The larger diameter cylinder in the middle section of the balance elbow shaft is located in the positioning groove, that is, the lower outer circumference of the larger diameter cylinder in the middle section of the balance elbow shaft rests on the cylindrical surface in the vertical direction corresponding to the left semi-circular arc of the positioning groove. The U-shaped shim 5 is supported between the base plate and the lower end face of the balance elbow, and the U-shaped shim is located on the outer circumference of the larger diameter cylinder in the middle section of the balance elbow shaft.

[0044] The lower end of the support bolt 4 is connected to the base plate, and the upper end of the support bolt 4 is used to support the lower end face of the balance elbow, located on the lower left side of the balance elbow.

[0045] The pressure plate 3 clamps the part, and the clamping bolt passes through the pressure plate 3. The lower end of the clamping bolt is connected to the base plate 1. When the clamping bolt is in a free state, the part is placed on the base plate.

The device features a simple structure, low cost, and easy operation, and is suitable for products of the same type but different sizes.

[0047] The U-shaped support pad on the upper end of the positioning groove supports the direct support surface of the part. Due to the radius of the arc of the positioning groove (width limitation), the part can only be placed vertically, inserted into the positioning groove from the open side. In this way, the part is clamped between the positioning groove and the base plate. The balance elbow shaft is located inside the positioning groove, and the balance elbow is located above the base plate, achieving accurate positioning of the part on the base plate. The arc diameter and width of the positioning groove are set to match the bottom dimensions of the clamped part.

[0048] This utility model can quickly position the balance elbow assembly parts on the base plate. At the same time, this tooling has the characteristics of simple structure. In order to make the device applicable to the processing of balance elbows of various vehicle models, the support bolts can be replaced with different lengths, and the clamping plate can be replaced according to the external dimensions of the parts. The clamping is completed efficiently and safely without the need for manual labor to spend a lot of time and effort, reducing the labor intensity of operators while ensuring safe production.
