Description

Technical Field

[0001] The invention relates to the technical field of camshaft processing, in particular to a fixing and clamping device for camshaft processing. Background Art

[0002] The camshaft is a component in a car's piston engine. It is specifically responsible for driving the valves to open and close on time, ensuring that the engine regularly draws fresh combustible mixture into the cylinder during operation and discharges the burned exhaust gas from the cylinder in time. In actual installation, it needs to be supported by a special bracket.

[0003] During the processing of the camshaft, a clamping device is required to fix it. When clamping the camshaft, most existing clamping devices can only clamp camshafts of the same model at the same time, and when processing different parts, they need to be transferred between different clamping devices, which is time-consuming.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a fixing clamping device for camshaft processing is proposed. Summary of the invention

The moving block is fixedly connected to the left side of the clamping block, and a spiral groove is opened on the left surface of the moving block. The moving block is slidably connected to the spiral ring through the spiral groove.

[0011] Furthermore, the flipping assembly includes a waste discharge chamber, an impeller, a flipping motor and a clamping block. A waste discharge chamber is opened in the middle of the base plate, and an impeller is rotatably connected in the waste discharge chamber. The front end of the middle impeller is fixedly connected to the flipping motor, and the rear end of the impeller is symmetrically fixedly connected to the clamping block. A transmission structure is formed between the impellers through belts and pulleys.

[0012] Furthermore, the flip assembly also includes a shaft, a push rod, a socket, a cavity and a slot. The rear end of the base plate is fixedly connected to the shaft, and the push rod is fixedly connected inside the shaft. The front end of the push rod is fixedly connected to the socket, and a cavity is provided in the center of the socket. The cavity is symmetrically provided with slots around it. The block is slidably connected to the socket through the slot, and the impeller is slidably connected to the socket through the cavity.

[0013] Furthermore, the clamping assembly includes a limit rod, a pull rod and a lifting plate. The limit rods are symmetrically fixedly connected to the front and rear sides of the left and right ends of the base plate, and the pull rods are fixedly connected to the middle of the left and right ends of the base plate. The upper end of the limit rod is slidably connected to the lifting plate.

[0014] Furthermore, the clamping assembly also includes a slide groove, a slide rail, a slide way, a skateboard, a cross bar, a connecting rod and a driving wheel. A slide groove is opened in the middle of the lifting plate, and slide rails are symmetrically opened on the front and rear sides of the lifting plate. The lifting plate is symmetrically opened on the front and rear sides of the slide rails. A skateboard is engaged and connected in the slide groove, and a cross bar is rotatably connected to the upper part of the skateboard. Connecting rods are symmetrically rotatably connected at both ends of the cross bar, and the other end of the connecting rod is rotatably connected to the driving wheel.

[0015] Furthermore, the clamping assembly also includes a sliding rod, a V-block and a gear rod. The sliding rod is slidably connected in the slideway, and the lower end of the sliding rod and the upper surface of the base plate are fixedly connected to the V-block. The upper surface of the V-block at the lower end of the sliding rod is fixedly connected to the gear rod, and the gear rod is engaged with the driving wheel.

[0016] The present invention provides a fixing clamping device for camshaft processing, which has the following beneficial effects: when in use, camshafts of different diameters can be clamped at the same time, and the camshaft can be turned over during processing to facilitate processing of its end face; when processing the outer periphery of the camshaft, the camshaft can be automatically clamped and driven to rotate to facilitate processing.

[0017] 1. When the present invention is in use, the pull rod can first drive the slide plate to rise to the upper end of the slide groove, and then lift the lifting plate through the slide plate to make the limit rod come out of the lifting plate, and then the slide plate can be used to rotate the lifting plate on the pull rod, so that the camshaft can be placed in the V-block on the bottom plate, and the lifting plate can be rotated to reset it, and the pull rod can drive the lifting plate to descend through the slide plate. When the limit rod is stuck in the lifting plate, the limit rod can provide support for the lifting plate and limit it to prevent the lifting plate from continuing to descend. The pull rod drives the slide plate to continue to descend in the slide groove, and the slide plate can drive the driving wheel to descend in the slide rail through the cross bar and the connecting rod, and then drive the V-block on the lifting plate through the gear rod. They descend synchronously to clamp the camshaft, and the sliding rod can limit the V-block through the slideway to prevent the V-block from deflecting during the descent and causing loose clamping. When clamping camshafts of different diameters, after the V-block clamps the camshaft with a larger diameter, the gear rod stops moving, and the driving wheel can rotate on the connecting rod under the action of the gear rod, thereby driving the V-block connected to its lower end to continue to descend through another adjacent gear rod to clamp the camshaft with a smaller diameter, thereby achieving simultaneous fixation of camshafts of different diameters. In summary, when in use, the camshaft can be placed conveniently and clamped and fixed at the same time.

[0018] 2. When the camshaft is processed by the present invention, the flipping motor can drive the impeller to rotate in the waste discharge chamber, thereby sucking the debris generated during the processing into the waste discharge chamber and discharging it out of the bottom plate through the waste discharge chamber under the action of the airflow, thereby avoiding the accumulation of debris on the bottom plate and hindering the processing. When the end face of the camshaft is processed, the push rod can drive the clamping seat to slide in the shaft rod, insert the impeller into the clamping chamber, and make the clamping block fit into the clamping slot. At this time, the flipping motor can drive the clamping seat to rotate through the impeller, and then drive the bottom plate to rotate between the brackets through the shaft rod, flip the camshaft, and thus process the two end faces of the camshaft. After the flipping is completed, the push rod can drive the clamping seat to reset, so that the impeller cannot drive the bottom plate to rotate, thereby continuously removing chips. In summary, when in use, the camshaft can be conveniently flipped, thereby processing its end face, and chips can be removed during processing to avoid accumulation of debris.

[0019] 3. After the end surface processing is completed, the detector can locate the axis center line of the camshaft and control the lifting rod to drive the base and the pedestal to rise and fall, so that the base, the pedestal and the axis center line of the camshaft coincide. Then the telescopic rod can pull the pillar to move in the shifting groove, so that the two end surfaces of the camshaft are respectively pressed against the turntable and the pad. The driving motor is started to drive the rotating plate to rotate in the turntable, so that the spiral ring can drive the shifting block to move on the turntable through the spiral groove, and then drive the clamping block to move in the clamping groove to clamp the end surface of the camshaft. After clamping is completed, the driving motor continues to run, and the clamping block cannot continue to move in the clamping groove, and the rotating plate can apply force to the shifting block through the spiral ring and the spiral groove, so that the clamping block drives the turntable to rotate on the base under the restriction of the clamping groove, and then drives the camshaft to rotate, which is convenient for processing its periphery. In summary, when in use, the end surface of the camshaft can be clamped and the camshaft can be driven to rotate, thereby processing its periphery. BRIEF DESCRIPTION OF THE DRAWINGS
