Description

Technical Field

[0001] This utility model relates to the field of tooling fixtures, and in particular to an internal support type compressor housing handling fixture. Background Technology

[0002] During the manufacturing process of air conditioner compressors, the compressor housing needs to be transferred and transported between different processes. Currently, the handling of air conditioner compressor housings is usually done manually or using external clamps.

[0003] Manual handling typically requires a significant amount of physical labor, is labor-intensive, inefficient, and poses a safety hazard of slipping and causing injury. While external clamping can reduce manpower somewhat, it usually has the following drawbacks: First, improper clamping force control may leave indentations or scratches on the workpiece's surface, affecting the product's appearance quality; second, for variable-diameter housings, ordinary clamps struggle to achieve stable and adaptive clamping, easily causing the workpiece to sway or even fall off during lifting, resulting in poor handling safety. Utility Model Content

[0004] This utility model solves the above-mentioned problems in the handling of existing air conditioner compressor housings by providing an internally supported compressor housing handling fixture.

[0005] To solve the above-mentioned technical problems, this utility model provides an internal support type compressor housing handling fixture, characterized in that it includes: a mounting base plate, a drive device, a rotating shaft, at least two grippers, and a linkage mechanism; The driving device is fixedly mounted on the mounting base plate; The rotating shaft is rotatably mounted on the mounting base plate and symmetrically arranged on both sides of the driving device; The linkage mechanism includes two linkage bodies, the top ends of which are rotatably connected by a pin to form a herringbone structure; the bottom ends of the two linkage bodies are respectively fixedly connected to the rotating shaft. The gripper is fixedly mounted on the connecting rod body and arranged circumferentially along the axis of rotation; The power output end of the drive device is connected to the linkage mechanism and is used to push or pull the herringbone structure, so that the two linkage bodies swing around the pivot at their bottom as a whole, thereby directly driving the gripper to produce a radially outward or inward movement.

[0006] In a preferred embodiment of the present invention, the driving device includes a cylinder and a transmission rod. The number of transmission rods is the same as the number of connecting rod bodies. One end of each transmission rod is hinged to the piston rod of the cylinder, and the other end is hinged to the connecting rod body.

[0011] In a preferred embodiment of the present invention, the linkage mechanism is further provided with a connecting block, and a lifting ring is installed on the connecting block for connecting with external lifting equipment.

[0012] In a preferred embodiment of this utility model, the hinge point between the transmission rod and the connecting rod body is located between the pivot connection end and the top pin connection point of the connecting rod body.

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0016] Example 1 like Figure 1-2 As shown, this embodiment discloses an internally supported compressor housing transport fixture, including: a mounting base plate 1, a drive device, a rotating shaft 2, at least two grippers 3, and a linkage mechanism.

[0017] The mounting base plate 1 is arranged horizontally and serves as the mounting foundation for the entire fixture. It is typically a thick steel plate used to support and fix all other components.

[0018] The drive device is fixedly mounted at the center of the mounting base plate 1 by bolts. In this embodiment, the drive device is preferably a cylinder 4, but a hydraulic cylinder or an electric actuator or other linear drive element can also be used.

[0019] The rotating shaft 2 is rotatably mounted on the mounting base plate 1 via the bearing seat 6 and is symmetrically arranged on the left and right sides of the cylinder 4.

[0020] The linkage mechanism includes two linkage bodies 5, the top ends of which are rotatably connected by a pin 7 to form a stable "V"-shaped structure. The bottom ends of the two linkage bodies 5 are fixedly connected to or connected by a key to the rotating shafts 2 on both sides, so that the swing of the linkage bodies 5 can drive the rotating shafts 2 to rotate.

[0021] Specifically, the bottom end of the connecting rod body 5 has a rotating shaft connecting end 51 and a gripper mounting end 52, with the gripper mounting end 52 located above the rotating shaft connecting end 51. The rotating shaft connecting end 51 is fixedly connected to the rotating shaft 2. The gripper 3 is detachably mounted on the gripper mounting end 52 via a mounting block and is arranged circumferentially along the rotating shaft 2. The mounting block serves as a connecting base for reliably mounting and positioning the gripper 3. This detachable design facilitates the replacement or maintenance of the gripper 3.

[0022] The gripping surface of the clamp 3 is an arc-shaped surface adapted to the curvature of the inner wall of the compressor housing 11 to ensure maximum contact area. The arc-shaped surface is also bonded or covered with an adhesive layer, which is preferably a rubber or polyurethane material with a high coefficient of friction and good elasticity, which can effectively prevent slipping and also cushion and protect the inner wall of the housing 11.

[0023] The driving device also includes transmission rods 8 for connecting the driving device and the linkage mechanism. Specifically, the number of transmission rods 8 is the same as the number of linkage bodies 5, which is two in this embodiment. One end of each transmission rod 8 is hinged to the front end of the piston rod of the cylinder 4, and the other end is hinged to the corresponding linkage body 5. The hinge point is located between the shaft connection end and the top pin connection point of the linkage body. This position forms a force-saving lever. When the piston rod of the cylinder 4 extends, it pushes the upper part of the herringbone linkage mechanism through the transmission rod 8, causing it to "open," thereby driving the two shafts 2 to rotate in opposite directions. The principle of motion is as follows: when the driving device pushes or pulls the herringbone linkage mechanism through the transmission rod 8, it forces the two linkage bodies 5 to swing around their fixed connection point with the shaft 2 (i.e., the shaft connection end 51) as the center of rotation. Since the gripper 3 is fixedly installed on the gripper mounting end 52 of the connecting rod body 5, and there is a radial distance between the mounting point and the rotation center, the swing of the connecting rod body 5 will be directly converted into the radial displacement of the gripper 3, thus achieving opening and closing.

[0024] In addition, a connecting block 9 is provided on the linkage mechanism, and a lifting ring 10 is installed on the connecting block 9. The lifting ring 10 is used to connect to the factory's overhead crane, robot, or other lifting equipment, thereby realizing the lifting and transportation of the entire fixture and workpiece.

[0025] The working process or principle of this utility model is as follows: During the clamping and handling stages, such as Figure 3 As shown: External hoisting equipment lowers the clamp via lifting ring 10, allowing the entire clamp to enter the compressor housing 11. Subsequently, the piston rod of cylinder 4 extends, pushing the two transmission rods 8 forward. The transmission rods 8 push the upper part of the herringbone linkage mechanism, causing the linkage body to "open" around the top pin 7. This action drives the two rotating shafts 2 to rotate in opposite directions. The rotation of the shafts 2 is transmitted to the grippers 3, forcing the two grippers 3 to open radially outward, ultimately securing them firmly against the inner wall of the compressor housing 11. At this point, the compressor housing 11 can be safely transported to the target location using the hoisting equipment.

[0026] Release phase, such as Figure 4 As shown: Once the compressor housing 11 is positioned at the target location, the piston rod of cylinder 4 retracts, pulling the connecting rod body 5 via the transmission rod 8. This causes the herringbone linkage mechanism to "close," thereby driving the rotating shaft 2 to rotate in the opposite direction. The reverse rotation of the rotating shaft 2 causes the gripper 3 to retract radially inward, disengaging it from the inner wall of the compressor housing 11. Finally, the hoisting equipment lifts the clamp containing the released workpiece, completing one work cycle.

[0027] This utility model has the following advantages: Handling is achieved by radially clamping from inside the compressor housing. The clamping force acts on the inner wall of the product, completely avoiding scratches or indentations on the outer surface and significantly improving the product qualification rate.

[0028] The fixture is located inside the product and does not occupy external space, making it particularly suitable for operation in space-constrained molds or dense production lines, offering high flexibility.

[0029] The herringbone linkage mechanism converts the linear thrust of the drive unit into the rotational motion of the shaft, and then into the radial motion of the gripper. The force transmission path is clear, the action is smooth, the clamping force is large, and the self-locking performance is good.

[0030] By working with cylinders and other drive devices, it can achieve fully automated operation of clamping, lifting, transporting and releasing, freeing workers from heavy manual labor and improving production efficiency and operational safety.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
