Description

Technical Field

[0001] The utility model relates to a clamp, in particular to a clamp used for machining an engine timing cover, and belongs to the technical field of timing cover machining. Background Art

[0002] The engine cover is located under the hood and can reduce engine noise. The engine timing cover is mostly made of aluminum alloy castings, fixed to the side of the engine and connected to the cylinder block to protect the timing gear and chain. Its main function is sealing and noise reduction.

[0003] However, when processing the existing engine timing cover, it is generally necessary to fix it on the operating table through multiple limit assemblies. Since the timing cover is set in an irregular shape, the position of the limit assembly needs to be adjusted during the fixing process, which is inconvenient to operate and not easy to quickly clamp and fix the cover. Utility Model Content

[0004] The purpose of the utility model is to provide a clamp for machining an engine timing cover in order to solve the above-mentioned problem. The resistance mechanism rotates to drive the slide rod to reset. When the support plate drives the fixed block to slide, the rotating rod on the slide rod can contact the timing cover. When the slide rod slides into the fixed block, the steel ball can adjust its position according to the sliding distance of the slide rod, thereby facilitating the limiting of the two sets of rotating rod timing cover.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a fixture for machining an engine timing cover, comprising a fixed block, two of the fixed blocks are equipped with a limiting mechanism, the limiting mechanism comprises a slide bar and a rotating rod, the fixed block is slidably connected to a plurality of slide bars, the slide bar is rotatably connected to the rotating rod, the slide bar is provided with a through slot, the fixed block is provided with a clamping slot, the fixed block is clamped and connected with a baffle, the fixed block is symmetrically fixedly connected to two side plates, the top of the side plate is fixedly installed with a cover plate, the fixed block is provided with a plurality of steel balls, the fixed block is rotatably provided with an interference mechanism, the bottom end of the fixed block is fixedly connected with a support plate, the two support plates slide in the support mechanism, and the support mechanism is rotatably provided with a driving mechanism.

[0006] Preferably, a baffle is mounted in the slot, and the cover plate is connected in a snap-fitting manner to the baffle.

[0007] Preferably, a plurality of the steel balls are located between the baffle plate, the side plate and the slide rod, and the height of the baffle plate is greater than the height of the two side plates.

[0008] Preferably, the sliding rod is slidably connected to the cover plate, and the through groove is arranged in an inclined structure.

[0009] Preferably, the interference mechanism includes a rotating plate and a connecting shaft, the fixed block is rotatably connected to the connecting shaft, the rotating plate is fixedly installed on the connecting shaft, the fixed block is provided with a rotating groove, one end of the connecting shaft passes through the side wall of the fixed block and is fixedly connected to a rocker rod.

[0010] Preferably, the swing rod is rotatably connected to the fixed block and the side plate, and the higher end of the rotating plate is located at the through groove.

[0011] Preferably, a rotating plate is rotatably provided at the rotating groove, and the rotating plate is rotatably connected to the fixed block.

[0012] Preferably, the support mechanism comprises a mounting frame and a base, the support plate is slidably connected to the base, and two mounting frames are symmetrically fixedly mounted on the base.

[0013] Preferably, the driving mechanism comprises a rotating block and a screw rod, the rotating block is rotatably connected to the base, the rotating block is fixedly connected to the screw rod, two support plates are threadedly connected to the screw rod, and a slide groove is provided on the base.

[0014] Preferably, the slide groove has two sliding support plates, the threads at both ends of the screw rod have opposite directions, and the screw rod is rotationally connected to the base.

[0015] The beneficial effects of the utility model are as follows: before positioning the timing cover, the resistance mechanism can be rotated by hand first, and when the resistance mechanism rotates inside the fixed block, the through groove portion provided in the slide rod can be rotated, so that when the resistance mechanism contacts the inner wall of the slide rod, the slide rod is driven to slide on the fixed block; since side plates are fixedly installed on both sides of the fixed block, and a cover plate is fixed on the top of the side plate, the cover plate limits the top ends of several slide rods, when the slide rod is subjected to the resistance force, it can slide along the fixed block, so that the slide rod is convenient to reset before fixing the timing cover; the sliding of the slide rod can enlarge the space for storing the steel balls, The baffle plate engaged on the fixed block blocks the steel balls and prevents them from falling out of the fixed block. The timing cover is placed in the middle of the two sets of rotating rods and the driving mechanism is rotated to drive the two fixed blocks to slide toward each other, thereby causing the rotating rod to contact the side wall of the timing cover. Since the side walls of the timing cover have different shapes, the rotating rod can slide into the inside of the fixed block when contacting the side wall, thereby causing the end of the slide rod to squeeze the steel balls. The steel balls adjust their positions according to the sliding distance of the end of the slide rod, thereby causing several rotating rods to clamp the timing cover according to its shape.
