Description
Technical Field
[0001] This utility model relates to the field of automotive parts testing, specifically to testing equipment for automotive engines. Background Technology
[0002] Before a car engine is officially installed in a vehicle, it needs to undergo repeated test runs. After running for a certain period, the engine parts are disassembled and inspected to determine their wear. Then, the parts are reassembled and test runs continue for a period of time. The engine parts are then disassembled again and inspected to determine their wear. Through this repeated testing and monitoring of part wear, the actual service life of the engine after installation is determined.
[0003] When disassembling engine parts, workers can use long wrenches or long-handled disassembly tools to reach into the engine cylinder to remove the corresponding parts. However, it is inconvenient to remove the disassembled parts from the cylinder, especially small parts. Utility Model Content
[0004] The technical problem solved by this utility model is: during the test run of an automobile engine, when disassembling engine parts, workers can use long wrenches or long-handled disassembly tools to reach into the engine cylinder to disassemble the corresponding parts. However, it is inconvenient to remove the disassembled parts from the cylinder, especially small parts.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fixture for testing automotive engine parts, comprising a vertical long cylindrical component, a fixture cavity fixed at the bottom end of the vertical long cylindrical component, and a left and right gripper that cooperate with the fixture cavity. The vertical long cylindrical component is movably inserted into a slider, which is slidably fitted onto a horizontal extension arm, which is set on a testing workbench. A vertical long rod is movably fitted into the vertical long cylindrical component, and a gear is installed at the bottom end of the vertical long rod. The gear meshes with a pair of racks. The left gripper is fixedly connected to the rear rack of the pair of racks, and the right gripper is fixedly connected to the front rack of the pair of racks. Both the rear and front racks are fitted into the fixture cavity. The left and right grippers protrude downwards from the fixture cavity, and the vertical long rod protrudes upwards from the vertical long cylindrical component.
[0006] The horizontal extension arm is mounted on the column, which is inserted into the vertical tube. The vertical tube is equipped with fastening bolts to fix the column. The vertical tube is fixedly mounted on the turntable, which is pivotally connected to the turntable base via bearings. The turntable base is fixed on the worktable.
[0007] The engine is placed on the engine base on the workbench. After opening the engine block and removing the internal parts, the worker holds the vertical long cylinder and can move it along the horizontal extension arm using a slider, or raise and lower the vertical long cylinder. When the left and right grippers reach the part to be retrieved, the worker rotates the vertical long rod, driving the gear. The gear drives a pair of racks, which in turn cause the left and right grippers to close, clamping the part. Then, the worker pulls up the vertical long cylinder to remove the part from the engine block.
[0008] The horizontal extension arm has a strip groove, the slider is a sleeve, the center of the slider has a center hole that mates with the vertical long cylinder, and the outer side wall of the slider has a groove that mates with the side wall of the strip groove.
[0009] A limiting sleeve is fitted onto the vertical cylindrical component, and the limiting sleeve is fixed to the vertical cylindrical component by fastening screws. The limiting sleeve can abut against the slider. The limiting sleeve is located above the slider, and when the limiting sleeve abuts against the slider, the vertical cylindrical component is in its lowest position. The limiting sleeve abuts against the slider, keeping the clamp on the horizontal extension arm and preventing it from disengaging.
[0010] A bearing is provided between the vertical long rod and the vertical long cylinder, and the vertical long rod is pivotally connected to the vertical long cylinder through the bearing.
[0011] The inner wall of the fixture cavity is provided with a first guide block and a second guide block. The first guide block engages with the rear rack, and the second guide block engages with the front rack. Driven by the gears, the rear rack moves along the first guide block, and the front rack moves along the second guide block.
[0012] The bottom of the clamping cavity is equipped with a cover plate, and a jaw guide groove is opened on the cover plate. The left jaw and the right jaw cooperate in the jaw guide groove. Driven by the gear rack, the left jaw and the right jaw move along the jaw guide groove.
[0013] The top of the vertical pole has a first knob, which makes it easy for workers to rotate the vertical pole.
[0014] An L-shaped component is fixed to a vertical long rod. A roller frame is pivotally connected to the inner wall of the L-shaped component, and a roller is mounted on the roller frame. The roller contacts the outer wall of the vertical long rod. A second knob is provided on the pivot shaft of the roller frame. A damping sleeve can be fitted onto the pivot shaft to increase the resistance to rotation. When removing parts from the engine block, the worker needs to rotate the vertical long rod. At this time, the center line of the roller is parallel to the center line of the vertical long rod, allowing the worker to rotate the vertical long rod and drive a pair of jaws to clamp the parts. After clamping, the worker rotates the second knob to make the center line of the roller and the center line of the vertical long rod form a certain angle, such as 90 degrees. At this time, the friction between the roller and the vertical long rod can prevent the vertical long rod from rotating, thus locking the clamping state of the pair of jaws. Among them, the roller is preferably a rubber roller.
[0015] This utility model enables the vertical long cylindrical component to be raised, lowered, and translated. With the assistance of a turntable, it can also rotate, allowing the clamp at the bottom of the vertical long cylindrical component to quickly and accurately pick up parts from the engine cylinder. The vertical long rod allows for remote operation of the clamp and locking of the clamp to remove the clamped parts from the engine cylinder. Attached Figure Description
