Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, and particularly relates to a high-precision ball density measurement system. Background Art

[0002] In the qualification inspection of ball-shaped parts or workpieces, sphericity is an important reference index. The application document with the application number CN202320164967.8 previously applied by the applicant discloses a three-axis contact type sphericity rapid measurement device, which obtains the sphere diameter data in three mutually perpendicular directions through three groups of sensor groups to complete the measurement work of the sphericity of the sphere. However, this device can only be used to detect the diameter (sphericity) of the sphere and cannot complete the detection work of the sphere density, resulting in certain limitations in the use of the device. Moreover, when detecting the sphere diameter, it can only detect the diameter of a group of spheres in three perpendicular directions, resulting in certain deviations in the detection results of the sphere diameter. Content of the Utility Model

[0003] To solve the technical problems existing in the above background art, the utility model provides a high-precision ball density measurement system, which can complete the rapid measurement work of the sphere density while carrying out the sphere diameter measurement work.

[0004] The technical solution of the utility model is as follows:

[0005] A high-precision ball density measurement system includes a feeding device, a detection device, and a discharging device arranged in sequence. The feeding device and the discharging device are both arranged to be able to transfer the sphere in handover with the detection device, and the detection device can complete the detection work of the sphere diameter and density.

[0006] Specifically, the detection device includes a transfer mechanism. The transfer mechanism includes a horizontally arranged tray with an opening for supporting the sphere. The detection device also includes a mass detection mechanism arranged under the tray. The mass detection mechanism is arranged to be able to pass through the opening and jack up the sphere to complete the mass detection work of the sphere. One side of the tray is also provided with a volume detection mechanism for completing the volume detection work of the sphere on the opening. The volume detection mechanism is arranged to be able to complete the volume detection work of the sphere by detecting the diameter of the sphere; it also includes a detection host communicatively connected to the volume detection mechanism and the mass detection mechanism. The detection host is arranged to be able to receive the mass and density information of the sphere and complete the calculation work of the sphere density. Through the volume detection mechanism, the diameter information of the sphere can be obtained, and then the volume information of the sphere can be generated. By cooperating with the mass detection mechanism, the density information of the sphere can be obtained, ultimately ensuring that the detection results of the sphere parts or workpieces can be more accurate and effective.

[0007] As described above, a high-precision ball density measurement system, in terms of the structure of the quality inspection mechanism, includes a first bracket fixed under the support plate, and a weighing module capable of vertical sliding inside the first bracket. A top column is vertically arranged on the upper side of the weighing module, which is configured to pass through the opening and complete the lifting of the ball. When the ball is lifted, the weighing operation can be completed by the weighing module. After the weighing is completed, the ball can be placed on the opening again by moving the top column downward, so that the quality inspection of the ball can be simpler and faster.

[0008] As described above, a high-precision ball density measurement system, the detection device also includes a ball rotating mechanism arranged on one side of the support plate and capable of driving the ball on the opening to rotate. Based on this structure, multiple sets of volume (diameter) information of the ball can be detected through the volume detection mechanism, thereby ensuring the accuracy of the monitoring results of the ball volume detection mechanism.

[0009] Specifically speaking, the structure of the ball rotating mechanism includes a first bracket fixed on one side of the support plate, and a ball rotating motor slidably arranged on the first bracket and capable of periodically approaching the support plate. The driving end of the ball rotating motor is provided with a turntable, and the ball can be driven to rotate through the contact between the turntable and the ball.

[0010] As a preferred embodiment, in order to ensure that the rotation of the turntable can effectively drive the sphere to rotate, the horizontal plane where the contact side of the turntable and the sphere is located is located below the horizontal plane where the center of the sphere is located.

[0011] In a high-precision ball density measurement system as described above, the pallet is a circular structure, and there are multiple openings arrayed around the center of the circle; the transfer mechanism also includes a drive motor arranged on the lower side of the pallet, which is transmission-connected to the pallet and can drive the pallet to rotate. On the basis of this structure, the transportation of the balls can be carried out sequentially, and in conjunction with the transportation of the balls, the quality detection mechanism and the volume detection mechanism can be respectively carried out on the balls on the upper sides of different openings, that is, the quality detection work and the volume detection work of the balls can be carried out separately, which significantly improves the detection efficiency.

[0012] A high-precision ball density measurement system as described above, with respect to the structure of the volume detection mechanism, includes a diameter detection module, and the diameter detection module includes two sets of detection parts arranged relatively to each other; the detection part includes a push rod with an axis passing through the center of the sphere and capable of moving and pressing the sphere, and a displacement sensor capable of detecting its displacement is provided on one side of the push rod. By detecting the displacement of the push rod, the distance between the end of the push rod and the sphere in the initial state can be obtained, and then the diameter of the sphere can be judged according to the initial distance between the ends of the push rods of the two sets of detection parts, so that the detection result of the sphere can be more accurate, and finally the volume detection result of the sphere can be more accurate.

[0013] As a preferred embodiment, to further ensure the accuracy of the sphere volume measurement result, and thus ensure the accuracy of the sphere volume measurement result, there are three sets of diameter detection modules, and the axes of the ejector rods of the three sets of diameter detection modules are perpendicular to each other in pairs.

The volume detection mechanism 43 is configured to be able to complete the volume detection of the sphere by detecting the diameter of the sphere. On the basis of the above structure, the measurement system also includes a detection host communicatively connected to the volume detection mechanism 43 and the quality detection mechanism 42, which is configured to receive the mass and density information of the sphere and complete the calculation of the density of the sphere.
