Description

Technical Field

[0001] This utility model belongs to the field of new energy battery processing, and in particular relates to a telescopic positioning mechanism for processing the crossbeam of a new energy battery box. Background Technology

[0002] The crossbeam of a new energy battery box is a key supporting structural component inside or outside the battery box. It is mainly used to support the battery modules, transfer loads, and enhance overall rigidity and safety, making it one of the core components of the battery box structural design. The crossbeam requires high dimensional accuracy to ensure precise fit with other components of the battery pack and avoid welding gaps or assembly difficulties due to dimensional deviations.

[0003] When machining a crossbeam, the feed of the cutting tool must be strictly controlled, and the position of the crossbeam is also subject to higher requirements. In particular, when machining a crossbeam, it is necessary to clamp the crossbeam. At this time, the positioning of the crossbeam is very important for machining. Inaccurate positioning can easily result in the machined crossbeam not meeting the dimensional requirements. Summary of the Invention

[0004] This utility model provides a telescopic positioning mechanism for processing the crossbeam of a new energy battery box. It is used to clamp and position the crossbeam by extending it during positioning and retracting it during processing. At the same time, an airtightness test is used to determine whether the crossbeam is in place, ensuring accurate positioning.

[0005] The specific technical solution of this utility model is as follows: a telescopic positioning mechanism for processing the crossbeam of a new energy battery box, including a positioning cylinder seat for mounting on a tooling, a telescopic cylinder set on the positioning cylinder seat, and a positioning component fixed to the end of the telescopic rod of the telescopic cylinder. The front end of the positioning component is a positioning contact surface. An air passage is provided inside the positioning component, and the outlet of the air passage is located on the positioning contact surface. The plane where the outlet is located is on the same plane as the positioning contact surface. A position sensor is provided on the positioning cylinder seat, and the position sensor includes at least an extended position sensor.

[0006] The telescopic cylinder is fixedly mounted on the positioning cylinder seat, which is in turn fixedly mounted on the corresponding tooling. This allows the positioning mechanism to be positioned as needed. The positioning action is achieved through the telescopic cylinder, thus automating the positioning process. Before processing, when positioning is required, the telescopic cylinder extends to its final position to position the workpiece. After the workpiece is positioned and fixed, the telescopic cylinder retracts, and the workpiece can be processed. Whether the telescopic cylinder has extended to its final position is detected and determined by a position sensor. Positioning generally requires contact with the workpiece to restrict and determine its position. This positioning action is achieved through a positioning component at the end of the telescopic rod. The positioning contact surface at the front end of the positioning component is used to contact the workpiece, thus providing sufficient contact area. This application uses an airtightness test to determine whether the contact between the positioning contact surface and the workpiece meets the positioning requirements. An air passage is provided inside the positioning component, and an outlet for the air passage is provided on the positioning contact surface. After the positioning contact surface contacts the positioning surface of the crossbeam, as long as the air pressure in the air passage meets the requirements, it indicates that the outlet of the air passage is sealed, confirming that the contact between the positioning contact surface and the positioning surface of the crossbeam meets the requirements.

[0007] Preferably, mounting feet are provided on both sides of the lower part of the positioning cylinder seat, and mounting holes are provided on the mounting feet. A fixing hole for adapting to the telescopic cylinder is provided in the middle position of the positioning cylinder seat.

[0008] Preferably, the position sensor also includes a retracted position sensor, which is located at the bottom of the telescopic cylinder with its probe facing the tail end of the telescopic rod. The extended position sensor is located on the side wall of the telescopic cylinder body with its probe facing the side of the telescopic rod.

[0009] Preferably, the telescopic cylinder is a linear cylinder.

[0010] Preferably, the positioning component includes a positioning plate fixed to the end of the telescopic rod and a positioning block fixed to the positioning plate. The positioning plate is perpendicular to the axis of the telescopic rod, the positioning contact surface is located on the front end face of the positioning block, the positioning contact surface is perpendicular to the axis of the telescopic rod, and the outlet is located in the middle of the positioning contact surface.

[0011] Preferably, an anti-rotation component is fixed on the positioning block. This anti-rotation component has an anti-rotation contact plane that is flush with and in contact with the upper surface of the positioning cylinder seat. The anti-rotation component has a certain width, and its contact plane is flush with the upper surface of the positioning cylinder seat and parallel to the axis of the telescopic rod. Thus, as the telescopic rod extends and retracts, the anti-rotation component moves synchronously. The limiting structure formed by the contact plane between the anti-rotation contact plane and the upper surface of the positioning cylinder seat ensures that the positioning block can only move in a straight line, without deflection during the translation process. This ensures that the position of the positioning contact surface on the positioning block does not deflect, improving positioning accuracy.

[0012] Preferably, the front end face of the positioning block is divided into two parts: one part is a plane perpendicular to the axis of the telescopic rod, and the other part is an inclined surface, wherein the plane is convex and the positioning contact surface is located on the convex plane.

[0013] Preferably, the positioning plate, positioning block, and anti-rotation component are provided with interconnected air passages.

[0014] The beneficial effects of this utility model are: 1. By fixing the positioning cylinder seat to the tooling, the positioning mechanism can be set to the required position, and the position change is relatively convenient;

[0015] 2. The telescopic movement for positioning is achieved by using a telescopic cylinder, which automates the positioning process. A position sensor is used to detect and determine whether the telescopic cylinder has extended to the correct position, facilitating the positioning of the contact surface.

[0016] 3. The positioning contact surface at the front end of the positioning component is used to contact the workpiece. An air passage is set inside the positioning component, and the air passage outlet is set on the positioning contact surface. By detecting whether the air pressure of the air passage meets the requirements, it is confirmed whether the contact between the positioning contact surface and the positioning surface of the crossbeam meets the requirements, so as to ensure accurate positioning.

[0021] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings. Example

[0022] like Figure 1 Figure 2 Figure 3 As shown, a telescopic positioning mechanism for processing the crossbeam of a new energy battery box includes a positioning cylinder seat 1 for mounting on a tooling, a telescopic cylinder 3 set on the positioning cylinder seat, and a positioning component fixed to the end of the telescopic rod of the telescopic cylinder.

[0023] The positioning cylinder seat has a block-shaped structure. Mounting feet 10 are provided on both sides of the lower part of the positioning cylinder seat. Each mounting foot has three mounting holes 2. A fixing hole for adapting to the telescopic cylinder is provided in the middle of the positioning cylinder seat. The axis of the fixing hole is parallel to the mounting plane of the positioning cylinder seat.

[0024] The telescopic cylinder is a linear cylinder. It includes a cylinder body and a telescopic rod, with the cylinder body fitting into the fixing hole of the positioning cylinder seat. Position sensors are installed on the telescopic cylinder, including a retracted position sensor 11 and an extended position sensor 14. The retracted position sensor is located at the bottom of the cylinder, with its probe facing the tail end of the telescopic rod. A radial detection hole 12 is provided on the side wall of the cylinder body, with a detection bead 13 positioned slightly inward from the detection hole. The extended position sensor is located slightly outward from the detection hole, with its probe facing the detection bead.

[0025] The positioning component at the end of the telescopic rod includes a positioning pressure plate 5 fixed to the end of the telescopic rod and a positioning block 6 fixed to the positioning pressure plate. The positioning pressure plate is perpendicular to the axis of the telescopic rod. The front end face of the positioning block is divided into two parts: one part is a plane perpendicular to the axis of the telescopic rod, and the other part is an inclined surface. The plane is convex and is the foremost point of the telescopic positioning mechanism. The foremost point plane is the positioning contact surface 7. An air passage is provided inside the positioning component. The outlet 8 of the air passage is located on the positioning contact surface. The plane where the outlet is located is on the same plane as the positioning contact surface. The axis of the last section of the air passage is perpendicular to the positioning contact surface. The positioning contact surface is perpendicular to the axis of the telescopic rod. The outlet is located in the middle position of the positioning contact surface.

[0026] An anti-rotation component 9 is fixed on the positioning block. The anti-rotation component has an anti-rotation contact plane 15, which is flush with and in contact with the upper surface of the positioning cylinder seat. The anti-rotation contact plane is parallel to the axis of the telescopic rod. The air passage inside the positioning component extends to the positioning cylinder seat through the anti-rotation component.

[0027] After the positioning cylinder seat is fixed on the tooling, the telescopic cylinder is activated, and the telescopic rod drives the positioning component to extend. The extension position sensor and the detection bead work together to detect and determine the extension position of the positioning contact surface at the front end of the positioning component. The positioning surface of the crossbeam contacts the positioning contact surface. Then, air is introduced into the air circuit. The air pressure change in the air circuit is used to detect the sealing between the positioning contact surface and the positioning surface, thereby determining whether the crossbeam has completed positioning. After positioning, the crossbeam is clamped, and then the telescopic rod retracts. The retraction position sensor detects the retraction status of the telescopic rod.

[0028] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
