Abstract
The utility model discloses a crankshaft timing gear induction heating assembly anti-error device which is used for crankshaft timing gear induction heating assembly of an electronic fuel injection engine. A positioning base is respectively connected with a gear pin and an anti-error stopper; the gear pin is fixed in a circumferential positioning hole of the positioning base; and the anti-error stopper is fixed on an axial positioning surface of the positioning base through a bolt. During timing gear induction heating assembly, gear teeth with timing notches correspond to a working part of the anti-error stopper, and the gear is fixed through a positioning clamp. When a tooth error problem occurs, the gear teeth without a timing gap on the gear interfere with the working part of the anti-error stopper, the end face of the gear cannot be tightly attached to the axial positioning surface of a positioning clamp, and the inner hole of the gear is not concentric with the crankshaft, so that the timing gear cannot be pressed to the shaft neck of the timing gear of the crankshaft, and the operator can immediately find the tooth error problem. The crankshaft timing gear induction heating assembly anti-error device is simple in structure and convenient to use, the labor intensity of a worker can be reduced, and the phenomenon that the product quality is influenced by the human factors is avoided.
Description
Technical field
The utility model relates to auto parts and components mounting technology field, is a kind of error prevention device that is used for the assembling of BBG crankshaft timing gear eddy-current heating specifically.
Background technology
At present, hot cover process is all adopted in the assembling of the timing gears of BBG bent axle.During assembling, gear is placed on the positioning fixture, heats bore with induction heating method, reach uniform temperature after, promote the gear axle journal of positioning fixture by cylinder with bent axle on the geared sleeve.But when placing gear, its, locating notch sign mainly leaned on range estimation to make it to identify corresponding with the correct time of positioning fixture in correct time.Because Production of Crankshaft is big in batches, gear breach in correct time location is depended on the artificial visually examine fully, is prone to cause personnel's visual fatigue, assembling side set problem occurs, and also is not easy behind the side set to find; In case timing gears assembling side set, the EFI crank assemblby will transfer out wrong signal in correct time after loading onto engine, causes the disorderly serious quality problems of engine operation order.
Summary of the invention
Existing EFI crankshaft timing gear eddy-current heating assembling is easy to generate side set and side set is not allowed detectable defective in order to solve; The goal of the invention of the utility model is to provide a kind of crankshaft timing gear eddy-current heating assembling error prevention device, reduces to zero with the quality risk that the installation of side set problem crank assemblby will be arranged.
For realizing above-mentioned purpose, the positioning pedestal of the utility model is connected with gear pin, mistake proofing block respectively; Gear pin is fixed in the positioning pedestal circumferential registration hole; The mistake proofing block is fixed on the positioning pedestal axial locating surface through screw.
The utility model designs a kind of mistake proofing block according to the breach gear teeth sign in correct time that designs on the timing gears, and the mistake proofing block is fastened on the gear positioning fixture axial locating surface through screw, and is corresponding with the breach gear teeth in correct time of gear.The hardness of mistake proofing block working position is suitable with timing gears hardness, and the long-term use in anti-stop block working position is extruded distortion and causes mistake proofing to lose efficacy.
During the assembling of timing gears eddy-current heating, there are the gear teeth of breach in correct time corresponding, gear fixed through positioning fixture with mistake proofing block working portion.As the side set problem appears; Then on the gear no correct time breach the gear teeth and mistake proofing block working portion interfere; Gear face and positioning fixture axial locating surface can not fit tightly; Bore will with the bent axle decentraction, then timing gears can't be pressed onto on the timing gears axle journal of bent axle, operating personnel at once just can find the side set problem.
The utility model compared with prior art, and is simple in structure, easy to use, can reduce labor strength, avoids human factor to influence product quality.
Description of drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Like Fig. 1, shown in Figure 2, positioning pedestal 1 adopts steel alloy to make, and the centre is a through-hole structure; Be used for cylinder promotion positioning pedestal and move forward and backward, 3 locating holes are arranged on positioning pedestal 1 circumference, be used to install gear pin 2; Gear pin 2 is a T shape structure; The employing spring steel is made, and mistake proofing block 3 is fixed on positioning pedestal 1 axial locating surface through screw 4, guarantees that mistake proofing block working position is corresponding with the breach gear teeth in correct time on the gear.
During use, earlier have the gear teeth of breach in correct time to aim at gear with mistake proofing block 3 working portions, then with geared sleeve in gear pin 2, gear face and positioning pedestal 1 axial locating surface fit tightly, the solid-state Intermediate Frequency Induction Heating Equipment that disposes with lathe heats gear.Because the gear pin 2 of fixed gear is flexible; After gear heating the rising large deformation, gear pin 2 is also made corresponding deformation thereupon, and bore is normally risen greatly; Keep that axle journal is installed is concentric with crankshaft toothed wheel, gear is press-fited to bent axle through cylinder promotion positioning pedestal 1.
