Description

A vertical balancing machine with weighing function Technical Field

[0001] The present application relates to the technical field of vertical balancing machines, and in particular to a vertical balancing machine with a weighing function. Background Art

[0002] A vertical balancing machine refers to a balancing machine in which the axis of rotation of the rotor being balanced is in a plumb state on the balancing machine. Generally, disc-shaped workpieces without a rotating axis, such as fan blades, water pump impellers, range hood impellers, flywheels, grinding wheels, saw blades, chucks and brakes, are suitable for testing on a vertical dynamic balancing machine.

[0003] When performing dynamic balance measurements on an object to be tested, such as a fan blade, a vertical balancing machine in the prior art needs to first fix the object to be tested with a special fixture before the dynamic balance measurement can be performed. For some objects to be tested, such as plastic parts molded by injection molding, weight will also be used as a quality inspection indicator for the product to be tested, and a weighing link is often required. Regardless of whether it is set before or after the dynamic balance measurement, the inspector needs to perform an additional weighing inspection process, which is relatively cumbersome. Utility Model Content

[0004] In order to realize the integration of weighing and dynamic balancing measurement to simplify the detection process of the object to be tested, the present application provides a vertical balancing machine with a weighing function.

[0005] The present application provides a vertical balancing machine with a weighing function adopting the following technical solutions:

[0006] A vertical balancing machine with weighing function, comprising

[0007] A balancing machine body, wherein the balancing machine body is used to measure the dynamic balance index of the object to be measured;

[0008] a mounting base, the mounting base being located below the balancing machine body, the mounting base being connected to a weighing unit, and the balancing machine body being capable of abutting against the weighing unit;

[0009] A fixing unit is installed on the mounting base and connected to the balancing machine body, and is used to fix the balancing machine body when measuring the dynamic balance index of the object to be measured.

[0010] By adopting the above technical solution, the fixture is installed on the balancing machine body, and then the object to be measured is clamped and fixed by the fixture. After the object to be measured stops shaking, the fixing unit is adjusted, and the fixing unit stops fixing the balancing machine body. At this time, the balancing machine body naturally falls, and the weighing unit measures the total mass according to the weight it bears. Since the weight of the balancing machine body and the fixture is known, the mass of the object to be measured can be obtained. After the mass measurement of the object to be measured is completed, the fixing unit fixes the balancing machine body and starts the dynamic balancing measurement. The designed vertical balancing machine with weighing function can perform dynamic balancing measurement by combining the balancing machine body with the fixture. The installation base facilitates the installation of the weighing unit and the fixing unit. The weighing unit facilitates the measurement of the total mass of the balancing machine body, the fixture and the object to be measured, and then the mass of the object to be measured is obtained. The fixing unit facilitates the control of the rigid connection state between the balancing machine body and the installation base, so that the balancing machine body is in a fixed state during dynamic balancing measurement and in a naturally falling state during mass measurement, realizing the integration of weighing and dynamic balancing measurement and simplifying the inspection process of the object to be measured.

[0011] In a specific embodiment, the weighing unit comprises

[0012] a mounting beam connected to the mounting base, with one end of the mounting beam extending below the balancing machine body;

[0013] A sensor gasket is connected to the mounting beam and is located below the balancing machine body and is capable of abutting against the balancing machine body.

[0014] By adopting the above technical solution, the designed weighing unit can easily carry the total mass of the balancing machine body, fixture and object to be measured through the installation beam, and can easily cooperate with the installation beam shape to carry the total mass of the balancing machine body, fixture and object to be measured through the sensor gasket.

[0015] In a specific embodiment, the fixing unit includes

[0016] A fixed cross bar connected to the balancing machine body;

[0017] Two clamp bodies, the clamp bodies are connected to the mounting base, and the clamp bodies are provided with a through slot for the fixed cross bar to extend into, the two clamp bodies are respectively arranged at both ends of the long side of the fixed cross bar, and the clamp bodies are slidably connected to two clamping blocks, the two clamping blocks are respectively arranged on opposite sides of the fixed cross bar, and the sliding direction of the clamping blocks is arranged horizontally;

[0018] A driving member is connected to the clamp body and the clamping block, and is used to drive the clamping block to slide toward or away from the fixed cross bar.

[0019] By adopting the above technical solution, a sliding gap is left between the clamping block and the fixed cross bar during weighing. When dynamic balancing is measured, the driving part applies force to the clamping block, and the clamping blocks on both sides move toward one side of the fixed cross bar until the fixed cross bar is clamped and fixed. At this time, the balancing machine body and the mounting base are rigidly connected; the designed fixing unit facilitates the coordination of the clamping block and the driving part to achieve the fixation of the fixed cross bar through the clamp body, and the clamping block can provide motion limit for the fixed cross bar and achieve clamping and fixation.

[0020] In a specific embodiment, the driving member includes

[0021] An air pump, the air pump being arranged on one side of the mounting base;

[0022] Two air pipes, two accommodating cavities for the sliding of the clamping block are opened in the clamp body, one end of the air pipe is connected to the air outlet end of the air pump, and the other end is connected to the clamp body, which is used to extract or transport gas into the accommodating cavity.

[0023] By adopting the above technical solution, the air pump works and delivers gas to the accommodating chamber through the air pipe. When the pressure in the accommodating chamber increases, the clamping block is pushed to slide toward the side of the fixed cross bar until the fixed cross bar is clamped and fixed. The air pump and the air pipe are used to easily control the pressure in the accommodating chamber, thereby driving the clamping block to slide to achieve the clamping action of the fixed cross bar. By extracting the gas in the accommodating chamber, the clamping block can be driven to retreat.

[0024] In a specific embodiment, the driving member includes

[0025] Two micro cylinders are connected to the clamp body, the micro cylinder piston rods extend into the clamp body and are connected to the clamping block, and the micro cylinder piston rods are staggered with the clamp body.

[0026] By adopting the above technical solution, the clamping block can be driven to move by the micro cylinder to achieve the clamping action of the fixed cross bar.

[0027] In a specific possible implementation manner, the fixed cross bar is detachably fixedly connected to the balancing machine body.

[0028] By adopting the above technical solution, when weighing is not required, the balancing machine body can be disassembled and dynamic balance measurement can be performed independently.

[0029] In a specific possible implementation manner, the fixed cross bar is connected to the balancing machine body via a plurality of fixing bolts.

[0030] By adopting the above technical solution, the fixing bolts can realize the detachable fixed connection between the fixed cross bar and the balancing machine body simply and at low cost.

[0031] In a specific possible implementation manner, the fixing cross bar is disposed through the balancing machine body, and the fixing cross bar is clamped and fixed to the balancing machine body.

[0032] By adopting the above technical solution, a detachable fixed connection between the fixed cross bar and the balancing machine body can be achieved through snap-fit ​​fixation.
