Embodiment Construction

[0015] The specific content and working process of the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0016] refer to figure 1 : the present invention adopts the method that knurling and assembling are carried out simultaneously to design. The knurling device 30 is installed above the camshaft assembly position (that is, the position where the cam 25 is placed). First, under the downward push of the cylinder push rod 18, the chuck 23 clamps the mandrel 24 of the camshaft, and the motor 3 can be an AC servo motor, which drives the transmission gear 5 to rotate through the high-speed transmission ratio mechanism of the gear box 4. The gear 5 is connected with the nut 7 of the ball screw 6, which drives the nut 7 to rotate, and the ball screw 6 moves down quickly. Sliding, the lower end of the slide block 12 is connected with the mandrel 24 clamping rotation mechanism. Since the ball screw 6 moves dow...

Abstract

The assembled axial cam knurled connection automatic assembling machine relates to an automatic connection equipment of assembled axial cam. The driving mechanism of said equipment is mounted on the top portion of the machine frame, it utilizes motor, gearbox and driving gear connected with nut on the ballscrew to drive ballscrew and make it upward and downward move, said ballscrew is connected with slide block sliding on the leaner guideway, the clamp rotating mechanism includes oil cylinder, oil cylinder outer cover fixed on the slide block and clamping chuck placed in the lower end of oil cylinder, on the cylinder a driving gear driven by motor is fixed, its liftout guide mechanism is a hydraulic oil cylinder fixed on the machine frame base seat, said liftout guide bar is connected with piston, and can be freely rotated.

Description

Technical field: [0001] The invention relates to an automatic connection device for an assembled camshaft Background technique: [0002] The camshaft is a key part of the engine. The traditional manufacturing method is mainly forging or casting, and the cam and the shaft are integrated. The assembled camshaft is manufactured separately from the mandrel made of steel pipe, the cam and the journal, and then assembled as a whole. Compared with the traditional manufacturing method, the assembled camshaft has the advantages of light weight, low production cost, and low material cost. Reasonable distribution, easy to manufacture and other advantages. The technical key to the production of assembled camshafts is the connection between the mandrel and the cam. At present, the devices used for the connection processing of the mandrel and the cam mainly include: a shrink-fit connection device, a laser welding method connection device and the like. For the device that adopts the knu...
