Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a vehicle-mounted component clamp used on an assembly line. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures.

[0003] New energy vehicles include hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV), hydrogen engine vehicles, other new energy vehicles (such as high-efficiency energy storage devices, dimethyl ether) and other product categories.

[0004] During the processing, various temporary fixtures are needed on the entire assembly line to ensure that the workpiece can be checked at any time. General fixtures only clamp in one direction, using two clamping arms to complete the simplest fixation. The clamping effect is generally poor and the workpiece is easy to fall off. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a vehicle-mounted component clamp for an assembly line, which utilizes two components, a main clamp arm and an auxiliary clamp arm, to double clamp a workpiece, has good clamping effect and high working efficiency.

[0006] In order to solve the above technical problems, the utility model provides a vehicle-mounted component clamp for an assembly line, including a base plate, a cylinder and a positioning seat are arranged on the base plate, a push rod is arranged at the output end of the cylinder, a first positioning shaft is arranged on both sides of the push rod on the base plate, connecting rods are arranged on both sides of the push rod, a main clamping arm is arranged on the connecting rod, and the main clamping arm is connected to the first positioning shaft; the push rod passes through the positioning seat and a top is arranged at the end, a second positioning shaft is arranged on both sides of the top head on the base plate, an auxiliary clamping arm is arranged on the second positioning shaft, and a push seat adapted to the top head is arranged at the bottom of the auxiliary clamping arm.

[0007] Furthermore, a mounting seat is provided on the base plate, and the cylinder is fixed on the mounting seat.

[0008] Furthermore, a buffer spring is arranged between the auxiliary clamping arms.

[0009] Furthermore, the stopper is a rotating wheel component, and the top is a semicircular component with a smooth surface.

[0010] Furthermore, a rotating shaft is provided at the position where the two connecting rods contact the abutment rod.

[0011] Furthermore, a V-shaped groove is provided on the main clamping arm.

[0012] Furthermore, a rubber head is provided on the auxiliary clamping arm.

[0013] The beneficial effects of the utility model are as follows: when the device is in use, the workpiece to be clamped is placed between the two main clamping arms, and the cylinder is started at this time, which drives the push rod to retreat. At this time, the retreat of the push rod drives the two connecting rods to move outwards. Since the middle of the main clamping arm is limited by the first positioning shaft, the outward movement of the connecting rod will drive the main clamping arm to move inwards, thereby achieving clamping. At the same time, the top head retreats at this time, and the buffer spring between the auxiliary clamping arms will drive the two auxiliary clamping arms to move inwards and achieve internal clamping of the auxiliary clamping arms; otherwise, the main clamping arm and the auxiliary clamping arm are opened, and the top head moves forward to drive the base at the bottom of the auxiliary clamping arm to move outwards, thereby opening the auxiliary clamping arm.
