Abstract
The utility model discloses a plate spring pin shaft retreating device which comprises a fixed connection device and a force application device, wherein the fixed connection device is formed by welding a bolt and a circular ring together, and the force application device comprises circular steel, a circular steel pipe, a retaining block and a connection hook. The circular steel pipe is movably sleeved on the circular steel, the retaining block is fixed at the rear end of the circular steel, the connection hook is arranged at the front end of the circular steel, and a handheld part is further arranged at the rear end of the circular steel. The specification of the bolt on the fixed connection device is matched with the dimension of a hole on a grease fitting exposed out of a plate spring pin shaft, the bolt can enter the hole of the grease fitting, the connection hook is connected with a circular ring on the fixed connection device, and by forcefully dragging the circular steel pipe on the force application device backwards fast, the connection hook on the circular steel can be dragged to move backwards to fast drag the pin shaft out. By means of the plate spring pin shaft retreating device, the plate spring pin shaft can be retreated easily, daily working efficiency is greatly improved, and safety hazard during assembling is avoided.
Description
Technical field
The utility model relates to a kind of frock of automobile manufacturing field, specifically is that a kind of leaf spring bearing pin moves back and takes off device.
Background technology
Because each replacing heavily card front and back leaf spring must be returned bearing pin, but the connecting hole gap of leaf spring bearing pin and bearing and leaf spring is very little, tolerance is almost 0, and it is very fastening that bearing pin is inlayed.When changing leaf spring, the chassis worker will get under the car, fiercely knocks the bolt of Φ 22 at every turn, just can slowly withdraw from for indirectly power and leaf spring bearing pin; And when knocking, a hand must hold on bolt with anti-slip, even effort has been returned bearing pin in addition; Bolt lets the leaf spring extruding of falling heavy rapidly live sometimes, also wants artificial lift to move leaf spring, just can return bolt; During this a series of actions, hammer can injure the hand of holding blunderbuss sometimes, and when returning bolt repeatedly, also hurts sb.'s feelings easily.Not only waste time and energy, can employee's personal safety be damaged also.
Summary of the invention
Move back the difficult problem of getting rid of poverty in order to solve the leaf spring bearing pin, the utility model provides a kind of moving back to take off light, safe and reliable leaf spring bearing pin and move back and take off device.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of leaf spring bearing pin moves back and takes off device; Comprise a firm joint device and a force application apparatus; Firm joint device is the welding body of a bolt and annulus, and force application apparatus comprises round steel, round steel pipe, block and butt hook, and the round steel pipe movable set is on round steel; Block is fixed on the rear end of round steel, and butt hook is located at the front end of round steel.
The size in the hole of the grease nipple that the specification of the bolt on the firm joint device and leaf spring bearing pin expose adapts; Bolt can the hole of enterprising grease nipple in; Butt hook is connected with annulus on the firm joint device; Firmly drag the round steel pipe on the force application apparatus backward rapidly, can affect on the round steel butt hook backward displacement can rapidly bearing pin be hauled out.
When changing leaf spring,, frock has been arranged no matter be propons or the back axle that heavily blocks; The workman need not to squat to lie to require great effort under the chassis again and knocks bearing pin, only need stand in outside the vehicle frame, firmly all can safely bearing pin be extracted in any case; Compared with getting in the past under the car, hold blunderbuss for one, the hand-tight hammer of holding; Also to firmly beat bearing pin and just can extract and made things convenient for a lot, have when former and hinder hand and hinder the phenomenon of eye and all can avoid, also protect employee's personal safety when satisfying work.
Through the application of the said frock of the utility model, the leaf spring bearing pin can easily be moved back take off, improved routine work efficient widely, stopped the potential safety hazard in the assembling process.
Description of drawings
Fig. 1 is the structural representation of this firm joint device.
Fig. 2 is the structural representation of force application apparatus.
Among the figure, 1-bolt, 2-annulus, 3-round steel, 4-round steel pipe, 5-block, 6-butt hook, 7-Handheld Division.
The specific embodiment
Requiring the technical scheme of protection to do below in conjunction with accompanying drawing to the utility model specifies.
The described a kind of leaf spring bearing pin of the utility model moves back and takes off device; Comprise a firm joint device and a force application apparatus; Firm joint device is the welding body of a bolt 1 and annulus 2, and force application apparatus comprises round steel 3, round steel pipe 4, block 5 and butt hook 6, and round steel pipe 4 movable sets are on round steel 3; Block 5 is fixed on the rear end of round steel 3, and butt hook 6 is located at the front end of round steel 3.The utility model is a characteristic of utilizing " active force has reaction ".Round steel pipe 4 affects butt hook 6 while and round steel 3 displacements backward when firmly dragging rapidly backward, butt hook 6 drives connected firm joint device and can rapidly bearing pin be hauled out, and is convenient and safe.
It below is a specific embodiment of the utility model.Annulus and a Q151C1235 bolt that firm joint device is 22mm by a diameter are welded, in the hole of the grease nipple that the Q151C1235 bolt just can enterprising leaf spring bearing pin exposes.Force application apparatus adopts following round steel pipe 4 to use diameter to process as the 3mm round steel pipe as the 24mm wall thickness, and round steel 3 diameters are 20mm, and round steel pipe 4 can be free to slide on round steel 3.Block 5 is the nut of Q363B22T13, firmly is welded on the round steel 3 with the limit displacement of spacing round steel pipe 4 on round steel 3.
Further, on the basis of above structure, also be provided with Handheld Division 7 in the rear end of round steel 3, people's held when being convenient to operate, the people stands in outside the vehicle frame, even exert oneself excessive any injury that also do not have.
