Description

Technical Field

[0001] The utility model relates to a loading and unloading jig, in particular to a loading and unloading jig for a clutch housing. Background Art

[0002] The clutch is an important part of the car. With the continuous development of the automobile industry, the demand for clutch housings has also increased, and it has shown a trend of multiple specifications and models. In the processing of clutch housings, most of them have adopted the form of loading and unloading by industrial robots to improve production efficiency.

[0003] The clutch housing has many specifications and different sizes. Different specifications of clamping fixtures are needed to clamp workpieces of different sizes. For processing stations that need to process clutch housings of different sizes, they need to be equipped with fixtures of various specifications. The overall configuration cost of the fixture is high, and for larger fixtures, the overall weight is larger, and the load requirements for the robot are also relatively large. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a loading and unloading fixture for a clutch housing which is light in weight, low in cost and capable of clamping workpieces of relatively large size.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a loading and unloading fixture for a clutch housing, comprising a fixture body with a connecting flange, a fixed base plate, a three-jaw cylinder, three extended jaws and three groups of guide mechanisms, wherein the fixed base plate is fixedly arranged on one side of the fixture body, the three-jaw cylinder is fixedly arranged on the fixed base plate, each of the extended jaws is radially fixedly arranged outwardly on one of the movable air jaws on the three-jaw cylinder, and each of the extended jaws is slidably arranged on the fixed base plate through a group of the guide mechanisms.

[0006] Compared with the prior art, the utility model has the advantage that by adding an extended jaw to the three-jaw cylinder, it can clamp light-weight and large-sized clutch housing parts. This structure can use a smaller-sized three-jaw cylinder to clamp larger-sized workpieces, reduce the overall cost of the fixture, and improve the economy of the fixture. At the same time, it can also reduce the overall weight of the fixture and reduce the load requirements for the robot; the existing three-jaw cylinder is selected and a pneumatic drive method is adopted to make the overall structure simpler while ensuring the clamping force, and the opening and closing actions of the claws become rapid, which speeds up the robot's action rhythm; the extended extended jaw is a mechanism for transmitting power and direction to the hand grasping part to realize the grasping and releasing of the claws. This mechanism adopts a translational movement form, and each extended jaw is slidably set on a fixed base plate through a group of guide mechanisms, which can improve the overall load strength of the extended jaws. When the cylinder of the three-jaw cylinder is opened or closed, the extended jaws act synchronously.

[0007] The extended clamping jaw includes an extended portion and a clamping portion. The inner end of the extended portion is fixedly arranged on one of the movable air claws on the three-claw cylinder. The bottom of the extended portion is slidably arranged on the fixed base plate through a group of guide mechanisms. The clamping portion is bent upward and fixedly arranged on the outer end of the extended portion. The extended portion and the clamping portion are generally integrally formed. The length of the extended portion can be set as needed, thereby expanding the clamping range of the three-claw cylinder. The overall weight of the fixture is light, reducing the load requirements on the robot.

[0008] The inner upper end of the clamping part is detachably provided with a first clamping block, and the inner lower end of the clamping part is detachably provided with a second clamping block. Each clamping part is equipped with two detachable and replaceable first and second clamping blocks, which can adapt to three clamping postures in the clutch housing processing process, and can be compatible with five clutch housing products of different specifications by replacing the clamping blocks to meet the actual production needs of customers; the design that the first and second clamping blocks can be quickly replaced is conducive to daily maintenance, and can be compatible with workpieces of more specifications and models, improving the versatility of the fixture.

[0009] The guide mechanism includes a slider and a linear guide rail. The linear guide rail is fixedly arranged on the fixed base plate along the moving direction of the movable air claw in a radial direction. The slider is slidably arranged on the linear guide rail and is fixedly connected to the extended jaw. The extended jaw is slidably arranged on the linear guide rail through a group of sliders, which can improve the overall load strength of the extended jaw.

[0010] The fixed base plate is provided with a plurality of positioning pin assemblies for positioning the clutch housing, so that the clutch housing can be quickly positioned during processing, thereby improving processing efficiency.

[0011] The other side of the fixture body is provided with a vacuum suction cup assembly for adsorbing the material tray partition, so that one fixture has two functions, reducing the overall cost and saving space.

[0012] The vacuum suction cup assembly includes six vacuum suction heads, and each of the six vacuum suction heads is a group of three and symmetrically distributed on both sides of the other side of the fixture body. Among them, each group of three vacuum suction heads is equipped with a solenoid valve and a vacuum generator, and each vacuum suction head is equipped with a vacuum logic valve and a buffer hardware to ensure reliable suction even when the partition is deformed. The above are all conventional structures of vacuum suction heads. BRIEF DESCRIPTION OF THE DRAWINGS
