Abstract

The utility model discloses a main core lifting device which is characterized in that a lifting air cylinder is reversely and fixedly arranged in a barrel body of an upper fixed pressing head at the bottom of a piston rod connection seat of the upper fixed pressing head, and a three-jaw type shutter is positioned at the rod end of a piston rod of the lifting air cylinder. The three-jaw type shutter is formed by a disk body and three clamp jaws, wherein the disk body is fixedly arranged at the rod end of the piston rod and provided with an annular clamp groove, all clamp jaws are hinged on the inner lateral wall of the upper fixed pressing head through pin shafts in the middles of the clamp jaws, and the upper ends of the clamp jaws are clamped in the clamp groove of the disk body, the lower end of the clamp jaws are fixed on an elastic body to surround the periphery of an upper shaft thread section of a main cone to clamp the main cone. The main cone lifting device enables the main cone to rise along with the upper fixed pressing head to be lifted.

Description

A kind of main cone lifting device

Technical field

The utility model relates to a kind of main cone lifting device, more particularly a kind of main cone lifting device that is applied in the vehicle bridge main cone bearing inner race press-loading process.

Background technology

Illustrated in figures 1 and 2 is vehicle bridge main cone bearing inner race press-loading process equipment in the prior art, seaming chuck 8 inserts in the upper fixedly pressure head 1 and connects with bolt 11, upper fixedly pressure head 1 is connected with piston rod Connection Block 2, lower bearing inner ring 9 is press fit on the desired location of main cone 10 by the upper fixedly pressure head 1 of piston rod Connection Block 2 promotions and seaming chuck 8, then piston rod Connection Block 2 is return, upper fixedly pressure head 1 and seaming chuck 8 rise, 10 of main cones that are pressed with lower bearing are stayed on the pallet 12, the main cone 10 that manually will press the lower bearing inner ring is removed, after pallet 12 is removed by transmission line body 13, again the main cone of removing is put on the push-down head 14, waits for next procedure; But main cone 10 is whole heavy, and volume is relatively large, is difficult for grasping by hand, and manually-operated is can not safety action accurate on the one hand, causes easily and collides with, damage master bevel gear face; The opposing party's a dead lift labour intensity is very large, and has the potential safety hazard that is injured by a crashing object by main cone.

Summary of the invention

The utility model is to be the weak point of avoiding above-mentioned prior art to deposit, and a kind of main cone lifting device is provided, and is applied in it and carries out the main cone lifting in vehicle bridge main cone bearing inner race press-loading process, to increase work efficiency, improves job security.

The utility model is that the technical solution problem adopts following technical scheme:

The design feature of the utility model main cone lifting device is: in the cylindrical shell of upper fixedly pressure head, be positioned at the fixedly bottom of the piston rod Connection Block of pressure head, be to be inverted and be fixedly installed a lifting cylinder, rod end at the piston rod of described lifting cylinder arranges a three-pawl type shutter, described three-pawl type shutter is to be fixedly installed on the piston rod rod end by one, disc with the annular draw-in groove consists of with three claws that are evenly distributed on the disc periphery, described each claw is to be hinged on the madial wall of fixed pressure head with bearing pin at the middle part of claw, the upper end of claw fixes in the draw-in groove of disc, and the lower end of claw encircles periphery in the upper male thread section of main cone by elastomer fixed thereon and forms clamping to main cone.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model utilizes the existing machinery that press-fits, and by the three-pawl type shutter is set, can realize accurate lifting, avoids damaging the master bevel gear face;

2, the utility model adopts cylinder as power source, airlift, the person's of lightening one's labor labour intensity;

3, the utility model does not need labourer to participate in directly, eliminates safe hidden trouble;

4, the utility model has enough chucking powers, and it is safe and reliable to guarantee to promote main cone;

5, the utility model is simple and reasonable, basic Maintenance free;

6, the utility model adopts compressed air as power, cleanliness without any pollution.

Description of drawings

Fig. 1 is the prior art structural representation;

Fig. 2 is another view of prior art;

Fig. 3 is the utility model structural representation;

Number in the figure: fixing pressure head on 1; 2 piston rod Connection Blocks; 3 lifting cylinders; 4 discs; 5 claws; 6 elastomers; Male thread section on 7; 8 seaming chucks; 9 lower bearing inner rings; 10 main cones; 11 bolts; 12 pallets; 13 line bodies; 14 push-down heads.

The specific embodiment

Referring to Fig. 1, the version of main cone lifting device is in the present embodiment: in the cylindrical shell of upper fixedly pressure head 1, be positioned at the fixedly bottom of the piston rod Connection Block 2 of pressure head 1, be to be inverted and be fixedly installed a lifting cylinder 3, rod end at the piston rod of lifting cylinder 3 arranges a three-pawl type shutter, the three-pawl type shutter is to be fixedly installed on the piston rod rod end by one, disc 4 with the annular draw-in groove consists of with three claws 5 that are evenly distributed on the disc periphery, each claw is to be hinged on bearing pin on the madial wall of fixing pressure head 1 at the middle part of claw 5, the upper end of claw 5 fixes in the draw-in groove of disc 4, and the lower end of claw 5 encircles periphery in the upper male thread section 7 of main cone 10 by elastomer fixed thereon 6 and forms clamping to main cone 10.

As shown in Figure 1, when the piston rod rod end of lifting cylinder 3 moves down, the claw of three-pawl type shutter namely opens, and removes the clamping to workpiece; When the piston rod rod end of lifting cylinder 3 upwards promotes, the claw of three-pawl type shutter is namely encircled periphery in the upper male thread section 7 of main cone 10 and is formed clamping to main cone 10, and this moment, main cone 10 was together promoted along with the lifting of upper fixedly pressure head 1.

The course of work:

Lifting cylinder 3 is descending, and disc 4 is opened claw 5, and claw 5 is in open configuration, and the piston rod Connection Block 2 of upper fixedly pressure head promotes upper fixedly pressure head 1 and seaming chuck 8 is pressed onto the position of wanting with the lower bearing inner ring; Subsequently, lifting cylinder 3 is up, and disc 4 is closed claw 5, and claw 5 is held male thread section on the main cone tightly by elastomer 6; The upper fixedly piston rod Connection Block 2 of pressure head is return, and upper fixedly pressure head 1 and seaming chuck 8 rise, and the main cone 10 that is held also is raised simultaneously, and after pallet 12 utilized line body 13 to pass through, the main cone 10 that will mention again was put on the push-down head 14, waited for next procedure.
