Description

Technical Field

[0001] The utility model belongs to the technical field of dynamic balancing machines, and more specifically relates to a vertical dynamic balancing machine with a weighing function. Background Art

[0002] A balancing machine is a machine that measures the size and position of the unbalance of a rotating object (rotor). When the rotor rotates around its axis, centrifugal force is generated due to the uneven distribution of mass relative to the axis. This unbalanced centrifugal force acts on the rotor bearings, causing vibration, noise and accelerated bearing wear, which seriously affects the performance and life of the product. Therefore, a balancing machine is required to detect the workpiece before it leaves the factory. A vertical dynamic balancing machine refers to a balancing machine whose drive spindle is installed vertically, which is suitable for detecting various parts without a spindle.

[0003] Existing vertical dynamic balancing machines usually include a chassis and a dynamic balancing mechanism fixed in the chassis. The workpiece clamping portion at the top of the dynamic balancing mechanism extends out of the top of the chassis. After the workpiece to be tested is fixed to the workpiece clamping portion, the balancing machine is started to drive the workpiece to rotate for testing.

[0004] Before performing a dynamic balancing test on a workpiece, it is usually necessary to weigh the workpiece first, and then during the detection process of the dynamic balancing machine, the workpiece is weighted and unweighted according to the test data each time. In the existing production process, the two links of weighing and dynamic balancing testing are independent of each other and need to be operated separately, and the steps are cumbersome. Utility Model Content

[0005] The utility model aims to solve the problem that the weight detection link and the dynamic balance test link of the workpiece to be measured need to be operated separately in the existing production process, which makes the operation steps complicated.

[0006] In order to achieve the above-mentioned object, the utility model provides a vertical dynamic balancing machine with a weighing function, comprising a fixed platform, a dynamic balancing system and a weighing system, wherein the dynamic balancing system comprises a base and a spindle module;

[0007] The weighing system includes a weighing sensor and a clamping assembly. The fixed platform is provided with a raised seat. The weighing sensor has a fixed end and a sensing end. The fixed end of the weighing sensor is connected to the raised seat. The sensing end of the weighing sensor is suspended on the raised seat.

[0008] The dynamic balancing system is arranged on the upper part of the sensing end of the weighing sensor;

[0009] The clamping assembly includes a clamping plate and clamping mechanisms arranged on two sides of the dynamic balancing system, the clamping plate is connected to the base, and the clamping mechanisms are used to clamp two ends of the clamping plate respectively to fix the dynamic balancing system.

[0010] Optionally, a recessed portion is formed in the middle of the top of the elevated seat, the fixed end of the weighing sensor is arranged on one side of the top of the elevated seat, and the sensing end of the weighing sensor is suspended above the recessed portion.

[0011] Optionally, the clamping mechanisms are fixed to the fixing platform via brackets respectively.

[0012] Optionally, the clamping plate is clamped on the base, and two ends of the clamping plate extend to two sides of the dynamic balancing system respectively.

[0013] Optionally, the clamping mechanism is a spindle brake or a pneumatic clamp.

[0014] Optionally, the spindle module includes a workpiece clamping portion at the top and a driving mechanism at the bottom, a vibration sensor is provided on one side of the driving mechanism, the workpiece clamping portion is connected to the driving end of the driving mechanism, the base is spaced apart at the bottom of the driving mechanism, and both sides of the driving mechanism are connected to the base through elastic parts respectively.

[0015] The beneficial effects of the utility model are:

[0016] The utility model discloses a vertical dynamic balancing machine with a weighing function, comprising a fixed platform, a dynamic balancing system and a weighing system, wherein the dynamic balancing system comprises a base and a spindle module; the weighing system comprises a weighing sensor and a clamping assembly, a raised seat is arranged on the fixed platform, the weighing sensor comprises a fixed end and a sensing end, the fixed end of the weighing sensor is connected to the raised seat, and the sensing end of the weighing sensor is suspended on the raised seat; the dynamic balancing system is arranged on the upper part of the sensing end of the weighing sensor; the clamping assembly comprises a clamping plate and a clamping mechanism arranged on two sides of the dynamic balancing system relatively, the clamping plate is connected to the base, and the clamping mechanism is used to respectively clamp the two ends of the clamping plate to fix the dynamic balancing system.

[0017] The utility model adds a weighing system at the bottom of the dynamic balancing system to achieve the weighing operation when the workpiece to be tested is subjected to the dynamic balancing test. In the initial state, the clamping assembly clamps the two ends of the clamping plate to fix the dynamic balancing system. When the workpiece to be tested is placed on the dynamic balancing system, the clamping assembly releases the two ends of the clamping plate. The dynamic balancing system and the part to be tested are pressed down toward the sensing end of the weighing sensor under the action of gravity, so that the weighing sensor measures the overall weight of the dynamic balancing system and the part to be tested. The weight of the part to be tested can be obtained by subtracting the known weight of the dynamic balancing system, thereby completing the weighing function; after the weighing is completed, the clamping mechanism re-clamps the clamping plate to fix the bottom of the dynamic balancing system, ensures the stability of the bottom of the dynamic balancing system to support the performance of the subsequent dynamic balancing test, starts the dynamic balancing system, and can perform the dynamic balancing test on the workpiece to be tested.

[0029] Specifically, in the embodiment of the utility model, the weighing sensor 310 is a single-point weighing sensor 310, which can measure the weight of the object above when its sensing end 312 is subjected to downward pressure. The elevated seat 110 is set to a concave shape to cooperate with the weighing sensor 310 to complete the weighing function.

[0030] Furthermore, in the embodiment of the present invention, the clamping mechanisms 322 are fixed on the fixing platform 100 through brackets 400 .

[0031] Furthermore, in the embodiment of the present invention, the clamping plate 321 is clamped on the base 210 , and two ends of the clamping plate 321 extend toward two sides of the dynamic balancing system 200 , respectively.

[0032] Specifically, in the embodiment of the utility model, a clamping plate 321 is provided, and when performing a dynamic balancing test, the clamping mechanism 322 clamps the clamping plate 321 to fix the base 210, thereby ensuring the stability of the bottom of the dynamic balancing system 200.

[0033] Furthermore, in the embodiment of the present invention, the clamping mechanism 322 is a spindle brake or a pneumatic clamp.
