Description

Technical Field

[0001] The utility model relates to the field of camshaft processing, and particularly relates to a device for processing radial holes of a camshaft. Background Art

[0002] A camshaft is an important component in an internal combustion engine, mainly used to control the opening and closing of engine valves. The camshaft operates the stroke of the valves through the cams thereon to ensure that the valves are opened or closed at the correct timing, so that the mixture of air and fuel can effectively enter the cylinder, thereby ensuring the efficient operation of the engine. The radial holes on the camshaft generally refer to the transverse holes drilled on the camshaft cylinder body. The design and functions of these holes can have various uses. The radial holes can be used as lubrication channels and for installing sensors, and can also be used to reduce weight and meet the requirements of some manufacturing processes. Therefore, a device is needed to fix and clamp the camshaft and drill holes in it.

[0003] In view of the above existing problems, a device for processing radial holes of a camshaft is specifically proposed. Content of the Utility Model

[0004] The utility model aims at the problems existing above, and specifically designs a device for processing radial holes of a camshaft. This device can process the radial holes of the camshaft, clamp and tighten the ends of the camshaft, has a better fixing effect on the camshaft, and improves the processing quality and safety.

[0005] To achieve the above object, the utility model provides a device for processing radial holes of a camshaft, including: a drilling machine, a clamping device, a mounting plate and a base. The clamping device is mounted on the mounting plate, the mounting plate is fixedly connected to the base, and the base is fixedly connected to the support platform on the drilling machine.

[0006] The clamping device includes a clamping part and a tightening part. The clamping part is mounted on one side of the mounting plate, and the tightening part is mounted on the other side of the mounting plate.

[0007] In the above way, two sets of clamping devices are provided and fixed on the support platform of the drilling machine. The two ends of the camshaft are clamped by the clamping part and tightened by the tightening part, so as to fix the camshaft, which is convenient for the subsequent drilling machine to process the camshaft.

[0008] Further, the clamping part includes: an electric cylinder, a telescopic rod, a connecting block, a crank and a clamping block. The electric cylinder is fixedly connected to the top of the mounting plate. One end of the telescopic rod is connected to the electric cylinder, and the other end of the telescopic rod is fixedly connected to the connecting block. The crank is rotatably connected to the connecting block, the middle part of the crank is rotatably connected to the mounting plate, and the end of the crank away from the connecting block is rotatably connected to the clamping block. The clamping block is slidably connected to the lower part of the mounting plate, and two such clamping blocks are arranged in the same way at the lower part of the mounting plate.

[0009] In the above way, the electric cylinder drives the telescopic rod to move up and down, the telescopic rod drives the connecting block to move up and down, the connecting block drives the crank to move with the point where the crank is connected to the mounting plate as the center, so that the crank drives the clamping block to move left and right on the mounting plate, and the two clamping blocks clamp towards the middle.

[0010] Further, the pressing part includes: a fixing plate, a pressing block and a linkage plate. One end of the fixing plate is fixedly connected to the side of the mounting plate away from the connecting block. The mounting plate is provided with a through hole at the joint of the two clamping blocks. The lower end of the fixing plate is fixedly connected with the pressing block, and the pressing block is placed in the through hole. The linkage plate is sleeved on the periphery of the mounting plate and fixedly connected to both sides of the connecting block, and the inner surface of the linkage plate is in contact connection with the fixing plate.

[0011] Further, the pressing part further includes a wedge block. The wedge block is a triangular prism structure. The wedge block is fixedly connected to the side of the fixing plate away from the pressing block, and the wedge block is fixedly connected to the surface of the linkage plate adjacent to the fixing plate. The two wedge blocks are in contact connection.

[0012] In the above way, when the connecting block moves down, it drives the linkage plate to move down. When the linkage plate slides, it squeezes through the wedge block on it and the wedge block on the fixing plate, so that the pressing block on the fixing plate presses and fixes the end of the camshaft.

[0013] Further, it further includes a slide rail. The slide rail is fixedly connected to the side of the mounting plate. The linkage plate is provided with a chute, and the linkage plate is slidably connected to the mounting plate through the chute and the slide rail.

[0014] Further, the clamping block is provided with a notch. The notch is located on the adjacent surface of the two clamping blocks, and the end of the camshaft is clamped at the notch.

[0015] In summary, the present utility model has the following advantages and beneficial technical effects:

[0016] 1. The camshaft radial hole processing device of the present utility model can radially clamp and axially press the camshaft, so that the fixing effect of the camshaft is better;

[0017] 2. The utility model uses an electric cylinder as a driving member to realize clamping in two directions in a camshaft radial hole processing device;

[0018] 3. The utility model provides a device for tightening and fixing a camshaft radial hole processing device, which has a simple structure and low maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS
