Description
Technical Field
The utility model belongs to the technical field of quick fixture, concretely relates to quick fixture in turbocharged engine rotor course of working.
Background
In turbocharged engine rotor course of working, traditional processing centre gripping mode is bar vice centre gripping, and the profile modeling is kept silent because of the clamping face is not uniform in size during the centre gripping, can only adopt V type piece form centre gripping, and this kind of mode has following shortcoming: 1. because the clamping is in line contact, the surface is easy to crush; 2. the automatic centering effect is poor when the clamping is carried out in the mode, and the over-poor symmetry is easily caused; 3. due to the fact that bolts are locked manually during clamping, efficiency is low, manual labor intensity is high, and safety accidents are caused due to the fact that workers are prone to fatigue. Therefore, the conventional technology has low efficiency, high labor intensity and extremely unsafe property, and has risks on the product quality.
Disclosure of Invention
The utility model provides a technical problem provide a quick fixture in turbocharged engine rotor course of working, the reducible traditional centre gripping mode human input cost of this quick fixture avoids the potential safety hazard, effectively improves production efficiency.
The utility model discloses a solve above-mentioned technical problem and adopt following technical scheme, quick fixture in the turbocharged engine rotor course of working, its characterized in that includes the work piece locating piece by last to setting gradually down, the collet chuck, backup pad and cylinder, the cylinder piston rod runs through the through-hole at backup pad middle part and the slider fixed connection in the collet chuck, displacement about in the collet chuck through the flexible slider that drives of cylinder piston rod, the slider cunning is joined in marriage in the straight section of thick bamboo cavity of collet chuck downside, the upper portion of straight section of thick bamboo cavity is equipped with by last throat form toper cavity down, straight section of thick bamboo cavity forms the location step with the junction of toper cavity, be equipped with the toper collet that matches with this toper cavity in the toper cavity, the bottom of collet is fixed through the gullet structure joint that matches with the upper portion of slider, turbocharged engine rotor joint is in.
Further preferably, a slider positioning groove is formed in one side of the slider, a slider limiting pin opposite to the slider positioning groove is arranged on the side wall of the collet, and the slider is limited in the collet up and down through the mutual matching of the slider limiting pin and the slider positioning groove.
Compared with the prior art, the utility model following beneficial effect has: compared with the traditional operation mode, the pneumatic valve control cylinder is adopted in the technology, a plurality of products can be clamped simultaneously, the production efficiency can be effectively improved, the coordinate center is unchanged all the time after different turbocharging engine rotors are clamped, and the phenomenon that the traditional mode leads to the situation that the bottom of the turbocharging engine rotor is clamped in place due to negligence of personnel and the product quality is unqualified can be effectively prevented.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a usage state diagram of the present invention.
In the figure: 1-workpiece positioning block, 2-collet chuck, 3-supporting plate, 4-cylinder, 5-cylinder piston rod, 6-slide block, 7-elastic collet, 8-turbocharging engine rotor, and 9-slide block limiting pin.
Detailed Description
The technical scheme of the utility model is described in detail with the attached drawings, the rapid clamping mechanism in the processing process of the turbocharged engine rotor comprises a workpiece positioning block 1, a collet chuck 2, a supporting plate 3 and a cylinder 4 which are arranged from top to bottom in sequence, a cylinder piston rod 5 penetrates through a through hole in the middle of the supporting plate 3 and is fixedly connected with a slide block 6 in the collet chuck 2, the sliding block 6 is driven to move up and down in the collet chuck 2 through the expansion of the cylinder piston rod 5, the sliding block 6 is matched in a straight cylinder cavity on the lower side of the collet chuck 2 in a sliding mode, a tapered cavity which is in a necking shape from top to bottom is arranged on the upper portion of the straight cylinder cavity, a positioning step is formed at the joint of the straight cylinder cavity and the tapered cavity, a tapered elastic chuck 7 matched with the tapered cavity is arranged in the tapered cavity, the bottom of the elastic chuck 7 is clamped and fixed with the upper portion of the sliding block 6 through a matched hook-and-groove structure, and a turbine supercharged engine rotor 8 is clamped and connected.
One side of slider 6 is equipped with the slider constant head tank, is equipped with the slider spacer pin 9 relative with the slider constant head tank on the 2 lateral walls of collet chuck, and is spacing from top to bottom in collet chuck 2 through mutually supporting realization slider 6 of slider spacer pin 9 and slider constant head tank.
The utility model discloses open pneumatic switch, the piston rod of the cylinder drives the slider and rises, the slider passes through the upper portion slot and is connected with collet chuck, it rises together to drive collet chuck by the slider, collet chuck opens the clamping that is at collet chuck deformation relaxation under self elastic action promptly so that turbocharged engine rotor, the collet chuck of packing into turbocharged engine rotor this moment, after turbocharged engine rotor packs into collet chuck, close pneumatic switch, the piston rod of the cylinder drives collet chuck decline through the slider this moment, collet chuck tightens up under collet chuck upper portion toper cavity's effect and takes place elastic deformation promptly, finally realize the clamp of turbocharged engine rotor and press from both sides tightly.
The utility model discloses a concrete use does: 1. the pneumatic switch is opened, the piston rod of the air cylinder moves upwards and drives the sliding block to move upwards, the groove in the upper portion of the sliding block and the groove in the lower portion of the elastic chuck are clamped and fixed with each other to drive the elastic chuck to move upwards, and at the moment, the elastic chuck is opened due to the fact that a gap exists between the elastic chuck and the collet chuck. 2. The turbocharging engine rotor is placed in the elastic chuck, the pneumatic switch is turned off, the piston rod of the air cylinder moves downwards at the moment, the sliding block is driven to move downwards at the same time, the sliding block drives the elastic chuck to move downwards together, the elastic chuck moves downwards to realize the tightening of the elastic chuck due to the fact that the taper of the conical cavity of the collet chuck is consistent with that of the elastic chuck, the turbocharging engine rotor is clamped at the moment, and the rapid clamping action of the turbocharging engine rotor is finally completed.
The foregoing shows and describes the general principles of the present invention, with its principal features and advantages, and further, various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
