Abstract

The invention relates to a spring clamping device for an automobile balancing machine. The spring clamping device is characterized by comprising three parts, namely a cylinder mechanism, a deformation beam mechanism and a clamping assembly and a lock body mechanism, wherein a piston rod is pushed to extend out from the inside of the cylinder, and the piston rod pushes a central shaft to move forward. The central shaft is in threaded connection with a lock body part, thus the lock body part moves forward; and at the same time, the central shaft compresses a spring sleeved on a main shaft, thus potential energy is accumulated. A tire is placed in the front end of a clamping shaft assembly through an embedded locking block, the compressed air is controlled to enter the cylinder from a reverse direction, thus the piston rod retracts into the cylinder, the spring on the main shaft is released simultaneously, the central shaft and the lock body part are driven to move backward, and the locking block and the clamping shaft assembly cooperate to clamp the tire, namely the tire can be driven by a belt pulley to revolve so as to detect the tire balance. By using the device provided by the invention, the tire is automatically locked, the tire is more stably and firmly clamped, and the safety and working efficiency are simultaneously improved.

Description

The equilibrator fixture of the spring

Technical field

The present invention relates to the equilibrator of a kind of motor vehicle repair, maintenance, particularly a kind of equilibrator use fixture of the spring.

Background technology

Along with the development of China's automobile industry, the application of wheel balance appearance is also more and more general.But traditional equilibristat is when tire clamps, though instrument such as quick nut is arranged, the set nut of still need exerting oneself comes the clamping tire, is time-consuming effort again.

Summary of the invention

For solving the problem that prior art exists, the present invention proposes a kind of potential energy that passes through the compression spring generation that passes through the potential energy auto lock tire of compression spring generation, auto lock tire.

Solve going a little of prior art, the technical scheme that the present invention takes is: this device is divided into three parts, cylinder mechanism, variable shaped beam mechanism, clamping group and and lock body mechanism; Wherein: cylinder mechanism, preceding cylinder cover and exhaust casing lid and cylindrical shell connect through four bolts, and the cylindrical shell two ends are by the sealing of cylindrical shell sealing O type circle; Piston is fixed on the piston rod with nut, stretches out in the cylinder cover before the piston rod, and by the Y-shaped ring sealing, the air admission hole control piston bar retraction that preceding cylinder cover and exhaust casing cover and stretching out; Variable shaped beam mechanism; Bearing and bearing lay respectively at the front and back ends of overcoat group welding piece, and supporting spindle rotates with belt pulley, and belt pulley is fixed on the supports main shaft by flat key and stripped nut; Flange is fixed on the supports main shaft with circlip for shaft, elastic spring, O type circle; Supports main shaft is a hollow, and central shaft passes two copper sheathings and also passes through pin and the movable spring washer arrangement end at spring, and the other end of spring is fixed by spring washer; The clamping group and and lock body mechanism, the iron bowl is connected with clamp shaft, the lock shaft device is in clamp shaft, two lock dogs connect lock shaft and lock dog axle, lock dog spring and cover acting in conjunction and lock dog, cover is by filling up and sunk screw is fixed.

The invention has the beneficial effects as follows: this equilibrator fixture of the spring, through the potential energy that compression spring produces, the auto lock tire, convenient and quick, it is more firm to let tire clamp, and has improved the security that clamps simultaneously, has improved operating efficiency.

Embodiment

As shown in Figure 1, the equilibrator fixture of the spring, structure is divided into three parts: cylinder mechanism A, the B of variable shaped beam mechanism, clamping group and with lock body mechanism C, the D among the figure is the signal of clamping tire.

Cylinder mechanism A, front air cylinder lid 11 and exhaust hood lid 1 and cylindrical shell 3 connect through four bolts 12, and the cylindrical shell two ends are by 2 sealings of cylindrical shell sealing O type circle; Piston 7 usefulness nuts 4 are fixed on the piston rod 13, and piston rod 14 stretches out in the cylinder head 11 in the past, and by Y-shaped ring 10 sealings, the air admission hole control piston bar retraction of front air cylinder lid 11 and exhaust hood lid and stretching out, seals at Y-shaped ring 6, O type circle 8.

The B of variable shaped beam mechanism; Bearing 20 and bearing 23 lay respectively at the front and back ends of overcoat group welding piece 25, and supporting spindle 14 rotates with belt pulley 28, and belt pulley 28 is fixed on the supports main shaft 14 by flat key 31 and stripped nut 21; Flange 16 usefulness circlips for shaft 22, elastic spring 29, O type circle 30 are fixed on the supports main shaft 14; As the usefulness that links to each other with clamp shaft, supports main shaft 14 is a hollow, the end that central shaft 17 passes two copper sheathings 27 and installs at spring 18 through pin 26 and movable spring packing ring 19; Another termination spring washer 15 of spring 18, spring washer 15 plays fixing spring 18.

The clamping group and with lock body mechanism C; Iron bowl 32 links together with clamp shaft 33; Lock shaft 34 device in clamp shaft 33 slidably 35, two lock dogs of two lock dogs 35 connect lock shafts 34 and lock dog axles 37, lock dog spring 36 can be pressed into and eject with cover 38 actings in conjunction and lock dog 35; Cover 38 is fixing with sunk screw 40 by pad 39, the position of playing fixed cover 38.

Principle of work

Pressurized air is got into by air intake opening, promotes piston rod 13 by stretching out in the cylinder, and front air cylinder lid 11 has two hooks to hook the round nut of variable shaped beam, and piston rod just promotes central shaft 17 and travels forward.Central shaft and the lock body part of being made up of lock dog 35, lock dog axle 34, lock dog spring 36, cover 38 are with being threaded, and lock body part is died and also travelled forward, and the while central shaft has also compressed central shaft spring 18, has accumulated potential energy.Pack into the front end of clamp shaft 33 combination of the lock dog 35 that tire passes through to be pressed into, at this moment, control pressurized air is by getting into cylinder in the other direction; Make piston rod 13 retraction cylinders; Two hooks of front air cylinder lid 11 are just thrown off with the round nut of variable shaped beam, and simultaneously, central shaft spring 18 discharges; Driving central shaft and lock body part moves backward; Lock dog and the acting in conjunction of clamp shaft subassembly clamp tire, and the clamp shaft subassembly partly connects together through bolt and variable shaped beam, can drive the balance that tyre rotation detects tire through belt pulley.
