Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a multi-point measuring cabinet. Background Art

[0002] A laser diameter gauge is an instrument for measuring the diameter of workpieces or materials with laser, which is widely used in industrial production and can realize automatic feedback control and online communication with a computer.

[0003] When the laser logging instrument is measuring, there is a measuring area between the laser emitting module and the laser receiving module for measuring the item to be measured. However, some items to be measured require a large number of measuring points, and the measuring area cannot completely cover multiple measuring points, so it is necessary to move the item to be measured for multiple measurements, which is inconvenient in operation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-point measuring cabinet, which drives the laser emitting module and the laser receiving module to move up and down to facilitate multi-point measurement.

[0005] The above technical purpose of the utility model is achieved by the following technical solutions: A multi-point measuring cabinet, characterized in that it comprises a cabinet, two lifting connection frames respectively arranged on both sides of the cabinet in a lifting manner, two first stepping motors arranged between the cabinet and the lifting connection frames and driving the lifting connection frames to lift, a laser emitting module arranged on one of the lifting connection frames, a laser receiving module arranged on the other lifting connection frame and corresponding to the laser emitting module, a material tray arranged in the middle of the cabinet for placing the item to be measured, a second stepping motor arranged between the cabinet and the material tray and driving the material tray to lift, a connecting cross beam arranged between one side of the laser emitting module and one side of the laser receiving module, a control panel is arranged on the cabinet and is signal-connected to the laser emitting module, the laser receiving module, the first stepping motor and the second stepping motor, and a display is arranged on the cabinet and is signal-connected to the control panel.

[0006] By adopting the above technical solutions, when the item to be measured is placed on the material tray, the two first stepping motors work simultaneously to drive the two lifting connection frames, the laser emitting module, the laser receiving module and the connecting cross beam to lift, so as to realize multi-point measurement of the item to be measured on the material tray; and the data of the display is used to display the data in real time during multi-point measurement; at the same time, it cooperates with the second stepping motor to drive the item to be measured to lift, which is convenient to adjust the height of the item to be measured, so that the area to be measured of the item to be measured can fall within the lifting measurement range of the laser emitting module and the laser receiving module.

[0007] A further setting of the present utility model is that double-optic-axis ball screw linear module guide rails are arranged on both sides of the cabinet, and the lifting connection frame is installed on the double-optic-axis ball screw linear module guide rails.

[0008] By adopting the above technical solution, by arranging the double-optic-axis ball screw linear module guide rails, the stability of the lifting connection frame during the lifting process can be improved.

[0009] A further setting of the present utility model is that a connecting sleeve is arranged on the lower surface of the material tray, and the motor shaft of the second stepping motor is rotationally connected to the connecting sleeve through a bearing.

[0010] By adopting the above technical solution, by enabling the material tray to rotate, it can be rotated by applying an external force during the measurement process, so as to measure the elliptical value of the object to be measured.

[0011] A further setting of the present utility model is that a limiting component for restricting the rotation of the material tray is arranged on the cabinet. A limiting hole is arranged on the circumferential side of the material tray. The limiting component includes a fixed tube arranged inside the cabinet, a telescopic rod whose lower end is telescopically arranged inside the fixed tube, an arc-shaped connecting block arranged at the upper end of the telescopic rod, and an elastic limiting member arranged on the arc-shaped connecting block and used for embedding or disengaging from the limiting hole.

[0012] By adopting the above technical solution, when the object to be measured does not need to rotate during the measurement process, the elastic limiting member is embedded in the limiting hole of the material tray for limiting, so as to restrict the rotation of the material tray; at the same time, the telescopic rod is telescopically arranged inside the fixed tube, so as not to affect the second stepping motor to drive the material tray to lift.

[0013] A further setting of the present utility model is that an installation opening is arranged on the part of the arc-shaped connecting block close to the circumferential side of the material tray. The elastic limiting member includes a limiting shaft telescopically arranged on the arc-shaped connecting block, a pull ring arranged at one end of the limiting shaft, an annular piece arranged in the installation opening of the limiting shaft, and a compression spring sleeved on the limiting shaft and having both ends abutted between the annular piece and the arc-shaped connecting block. When the compression spring is in a natural state, the limiting shaft is embedded in the limiting hole. When the pull ring is pulled outwards to overcome the elastic force of the compression spring, the limiting shaft is disengaged from the limiting hole.

[0014] By adopting the above technical solution, when the limiting shaft is aligned with the limiting hole, the limiting shaft is embedded in the limiting hole under the action of the compression spring, realizing the connection of the arc-shaped connecting block and the material tray, so as to restrict the rotation of the material tray; when the elastic force of the compression spring is overcome by pulling the pull ring, the limitation on the material tray can be released.

[0023] Implementation effect: When placing the item to be measured on the material tray 6, the two first stepping motors 3 work simultaneously to drive the two lifting connecting frames 2, the laser emission module 4, the laser reception module 5, and the connecting crossbeam 8 to lift, so as to realize multi-point measurement of the item to be measured on the material tray 6; and the data of the display 10 is used to display the data during multi-point measurement in real time; at the same time, the second stepping motor 7 is coordinated to drive the item to be measured to lift, which is convenient for adjusting the height of the item to be measured, so that the area to be measured of the item to be measured can fall within the lifting measurement range of the laser emission module 4 and the laser reception module 5.

[0024] By setting the double optical axis ball screw linear module guide rail 11, the stability of the lifting connecting frame 2 during lifting can be improved.

[0025] Embodiment 2: A multi-point measurement cabinet, as Figures 2 to 4 shown, the difference from Embodiment 1 is that: a connecting sleeve 61 is provided on the lower surface of the material tray 6, and the motor shaft of the second stepping motor 7 is rotatably connected to the connecting sleeve 61 through a bearing. A limiting component 12 for restricting the rotation of the material tray 6 is provided on the cabinet 1, a limiting hole 62 is provided on the peripheral side of the material tray 6, and the limiting component 12 includes a fixed tube 121 provided inside the cabinet 1, a telescopic rod 122 whose lower end is telescopically arranged inside the fixed tube 121, an arc-shaped connecting block 123 provided at the upper end of the telescopic rod 122, and an elastic limiting member 124 provided on the arc-shaped connecting block 123 and used for embedding or disengaging from the limiting hole 62.

[0026] An installation opening 1231 is provided on the part of the arc-shaped connecting block 123 close to the peripheral side of the material tray 6.
