Description

Technical Field

[0001] The utility model relates to the technical field of oil seal loading and unloading tooling, in particular to a quick-changing structure of oil seal loading and unloading clamping jaws. Background Art

[0002] An oil seal is a mechanical component used to seal oil. Its primary function is to prevent the outflow of internal fluids and the ingress of external contaminants. Specifically, an oil seal isolates the components of a transmission that require lubrication from the output components, preventing lubricant leakage. Widely used in mechanical equipment such as gearboxes and hydraulic cylinders, oil seals are an integral part of rotating and moving component assemblies.

[0003] In the current oil seal production process, many places require the use of a clamping jaw structure to grasp the oil seal for the next step. However, the current situation is that most clamping jaws are V-shaped jaws or contoured jaws.

[0004] When these grippers need to be replaced with other items, the operation is rather cumbersome: either the center of the gripper needs to be manually adjusted and the gripper needs to be tightened with bolts; or multiple types of contoured grippers need to be produced to correspond to each item.

[0005] The above operation method will not only make debugging more difficult and increase tooling costs, but also limit production efficiency. Utility Model Content

[0006] The main technical problem solved by the utility model is to provide a quick-changing structure for the upper and lower jaws of an oil seal, wherein the pin can be quickly installed into the pin seat, the slide groove and the rubber-coated T-shaped block and they are firmly and reliably connected together, thereby achieving the purpose of quick assembly, enabling quick changing and adjustment, and avoiding the debugging process; it can meet the use of multiple products, saving actual costs and improving production efficiency.

[0007] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a quick-change structure for the upper and lower jaws of an oil seal, comprising a cylinder and a quick-change assembly connected to the cylinder, through which the oil seal can be grasped and transferred to the next process.

[0010] The pin is installed on the pin hole 1 of the pin seat, and then passes through the positioning hole 1 on the slide, and at the same time passes through the positioning hole 2 of the rubber-coated T-shaped block to achieve rapid changeover.

[0011] In a preferred embodiment of the present invention, three cylinder mounting seats are provided at the bottom end of the cylinder, and the three cylinder mounting seats are evenly distributed in a circular shape at 120° intervals along the center of the cylinder.

[0012] In a preferred embodiment of the present invention, the top end of the cross-shaped connecting block is mounted on the bottom end of the cylinder mounting seat, and the bottom end surface of the cylinder mounting seat is provided with a cross mounting groove adapted to the cross-shaped connecting block.

[0013] In a preferred embodiment of the present invention, the bottom end of the cross-shaped connecting block is configured to be engaged with and locked in the sliding groove.

The first end face of the slide 3 is connected to the cylinder 1 through the cross-shaped connecting block 6, and the rubber-coated T-shaped block 5 is installed on the second end face of the slide 3.

[0036] Specifically, the pin seat 2 is installed on the first end face of the slide groove 3, the pin hole 2-1 is provided on the pin seat 2, the positioning hole 3-3 is provided on the slide groove 3, and the positioning hole 5-3 is provided on the rubber-coated T-shaped block 5. The positions of the pin hole 2-1, the positioning hole 3-3 and the positioning hole 5-3 are aligned.

[0037] The pin 4 is installed on the pin hole 1 2 - 1 of the pin seat 2 , and then passes through the positioning hole 1 3 - 3 on the slide 3 , and at the same time passes through the positioning hole 2 5 - 3 of the rubber-coated T-shaped block 5 to achieve rapid changeover and adjustment.

[0038] The utility model uses the pin 4, the pin seat 2, the slide groove 3 and the rubber-coated T-shaped block 5 in combination.
