Description

Technical Field

[0001] This utility model relates to the field of inspection equipment technology, and in particular to a pneumatic telescopic device for inspection tools. Background Technology

[0002] New energy batteries are the core components of new energy equipment. They mainly consist of lithium batteries as battery units. Multiple sets of lithium batteries are used to form a battery module, and then multiple battery modules are installed in the battery box.

[0003] As the mounting component for battery modules, the battery casing not only protects the batteries—for example, by possessing sufficient strength to prevent them from rupturing, exploding, or leaking under impact—but also serves other functions. Therefore, battery casings are typically made of metal frames with a certain level of mechanical strength. Since the battery casing needs to be mounted on working equipment and must remain stable after installation, it requires very high stability. Therefore, during manufacturing, it is necessary to create multiple mounting holes in the battery casing blank, and to maintain high precision in these holes, including their dimensions and the positional relationships between them.

[0004] After the inspection is completed, the positioning parts of the car battery box need to be ejected. Currently, most of them use mechanical structures such as springs and levers to eject the parts, but there are problems such as unstable ejection force, easy jamming, and short life. In addition, workers need to frequently intervene to remove the parts, resulting in low inspection efficiency. Furthermore, manual operation is prone to introducing secondary errors (such as part offset).

[0005] Therefore, those skilled in the art have provided a pneumatic telescopic device for inspection tools to solve the problems mentioned in the background art. Utility Model Content

[0016] Furthermore, a reinforcing plate is provided between the stabilizing action plate and the telescopic rod. The corner of the reinforcing plate is recessed inward to form a square notch. The stabilizing action plate and the reinforcing plate are connected by bolts, and the bolts are located inside the square notch.

[0017] Furthermore, the bottom end of the telescopic rod has a boss, the diameter of the top surface of the boss being larger than the diameter of the bottom surface of the boss.

[0036] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0037] See Figure 1-4 As shown;

[0038] The pneumatic telescopic device for a gauge according to an embodiment of this utility model includes:

[0039] A cylinder body 10 is installed in a preset position. Guide mechanisms 20 are provided on both sides of the cylinder body. A stabilizing plate 11 is connected to the output end of the cylinder body 10. The guide mechanism 20 is configured so that the output end of the cylinder body 10 drives the stabilizing plate 11 to move for guidance.

[0040] Telescopic rod 30, the top end of which is connected to the middle of the bottom surface of the stabilizing action plate 11;

[0041] A guide positioning mechanism 40 is disposed below the telescopic rod 30.

[0042] In this application, the cylinder body 10 serves as a power component, installed in a preset position, and drives the telescopic rod 30 to work via the stabilizing action plate 11.

[0043] The telescopic rod 30 is connected to the stabilizing action plate 11 and serves as an actuator to transmit power from the cylinder body 10, driving the telescopic rod 30 to perform actions such as extending, pushing out, and resetting.

[0044] The guide mechanism 20 is used to limit the movement direction of the stabilizing action plate 11 to prevent skewness.

[0045] The guiding mechanism 20 includes:

[0046] The left housing 21 and right housing 22 are symmetrically arranged on the left and right sides of the cylinder body 10.

[0047] Two guide holes 23 are respectively opened in the middle of the top surface of the left housing 21 and the right housing 22, and the guide holes 23 extend to the bottom surface of the corresponding left housing 21 and right housing 22;

[0048] Two symmetrically arranged guide rods 24 pass through corresponding guide holes 23 and are connected to both ends of the top surface of the stabilizing action plate 11.

[0049] When the cylinder body 10 is working, it pushes the stabilizing plate 11 to move. At the same time, the two guide rods 24 connected to the stabilizing plate 11 move in the corresponding guide holes 23 to limit the movement direction of the stabilizing plate 11, prevent the movement from deviating, ensure the stable movement of the telescopic rod 30, and ensure that the ejection force is stable and there is no jamming, so as to ensure the smooth operation of the telescopic rod 30.

[0050] A reinforcing plate 12 is provided between the stabilizing action plate 11 and the telescopic rod 30. The corner of the reinforcing plate 12 is recessed inward to form a square notch 13. The stabilizing action plate 11 and the reinforcing plate 12 are connected by bolts, and the bolts are set in the square notch 13.

[0051] The bottom end of the telescopic rod 30 has a boss 31, the diameter of the top surface of the boss 31 being larger than the diameter of the bottom surface of the boss 31. The bottom surface of the boss 31 can be a plane, an arc surface, or a curved surface to accommodate the ejection of different part positioning pins 43.

[0052] The stabilizing plate 11 and the reinforcing plate 12 are detachably connected by bolts, facilitating the replacement of different telescopic rods 30 and bosses 31 to accommodate different part positioning pins 43. This also ensures that the force output from the cylinder body 10 is stably transmitted to the telescopic rod 30.

[0053] The guiding and positioning mechanism 40 includes:

[0054] Positioning body 41, the positioning body 41 is set at a preset position, and the top surface of the positioning body 41 has an insertion hole 42 in the middle.

[0055] The part positioning pin 43 can be inserted into the insertion hole 42.

[0056] The telescopic rod 30 is positioned towards the part positioning pin 43. When the cylinder body 10 is working, it drives the telescopic rod 30 to press against the top of the part positioning pin 43 and stably pushes the part positioning pin out of the positioning body 41. This process does not require frequent manual intervention, avoiding low detection efficiency caused by frequent manual intervention and the possibility of secondary errors (such as part offset) easily introduced by manual operation.

[0057] The rear side of the positioning body 41 extends outward to form an auxiliary positioning block 44. The top surface of the auxiliary positioning block 44 is higher than the top surface of the positioning body 41, and the bottom surface of the auxiliary positioning block 44 is higher than the bottom surface of the positioning body 41, so that a stepped structure is formed between the positioning body 41 and the auxiliary positioning block 44.

[0058] The top surface of the auxiliary positioning block 44 has multiple circular holes 45 to reduce its weight.

[0059] The auxiliary positioning block 44 serves to position the part to be inspected, providing a stable foundation for the inspection.

[0060] When the gauge is in use, the device of this application is in the closed state, and the cylinder body 10 is not working;

[0061] When the gauge is finished, push the switch handle of the control cylinder body 10 forward and rotate it clockwise to extend the telescopic rod 30 and push out the part positioning pin 43 in the positioning body 41. After it is pushed out, push the switch handle of the control cylinder body 10 forward and rotate it counterclockwise to reset the telescopic rod 30.

[0062] The device in this application uses a cylinder body 10 to drive the extension of the telescopic rod 30 and push out the part positioning pin 4, which solves the problems of unstable push-out force, easy jamming, and short life. It eliminates the need for frequent worker intervention to pick up parts, solves the problem of low detection efficiency, and avoids scratches or deformation caused by manual operation.

[0063] The device proposed in this application features fast response, cleanliness and no pollution, and significantly improves the automation level of inspection tools, meeting the environmental requirements of automobile manufacturing workshops.

[0064] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
