This embodiment provides an auxiliary measuring device, which includes:

a base set on a reference plane;

a sliding mechanism disposed on the base and moving towards the reference plane under a pressure; and

A displacement sensor is arranged on the base to record the displacement of the sliding mechanism.

The auxiliary measuring device provided by this embodiment will be described in detail below with reference to the figures. The auxiliary measuring device described in this embodiment cooperates with the grasping servo device for grasping the product to be tested and moving the product to be tested to the detection position, and the auxiliary measuring device can be measured by pressing the grasping servo device The compressive displacement of a device relative to the reference plane on which it is placed. In this embodiment, the grasping servo device is erected on a support on the measurement platform, and the top of the support is provided with a moving guide rail for guiding the grasping servo device to move from the feeding position to the detection position; the auxiliary measurement The device is placed on the measurement platform, and the plane of the measurement platform is set as a reference plane. In this embodiment, a microwave oven is the product to be tested. The grasping servo device moves the microwave oven from the incoming material position to the detection position, and the auxiliary measuring device is arranged at the bottom of the four feet of the microwave oven.

Please refer to FIG. 1 and FIG. 2 , which are respectively a three-dimensional structural schematic diagram and a side view of the auxiliary measuring device. As shown in FIGS. 1 and 2 , the auxiliary testing device 1 includes a base 11 , a displacement sensor 12 , a sliding mechanism 13 , a stroke adjustment block 14 and an elastic component 15 .

The base 11 is the reference of the auxiliary measurement device, and is set on a measurement platform as a reference surface. The displacement sensor 12 , the sliding mechanism 13 and the stroke adjustment block 14 are all arranged on the base 11 . The bottom of the base is provided with a mounting hole (not shown) for fixing on the measuring platform. The base 11 is configured as a table. A lug 111 is provided at a position corresponding to the sliding mechanism 12 on the top of the table. A first supporting hole 112 is defined on the lug 111 .

In this embodiment, the displacement sensor 12 is a linear displacement sensor whose function is to convert the linear mechanical displacement into an electrical signal. In order to achieve this effect, the variable resistance slide rail is usually fixed at the fixed position of the sensor, and different resistance values are measured by the displacement of the slide on the slide rail. The sensor slide rail is connected to a steady-state DC voltage, allowing a small current of microamperes to flow, and the voltage between the slide and the starting end is proportional to the length of the slide. Using the sensor as a voltage divider minimizes the need for accuracy in the overall resistance of the slide since changes in resistance due to temperature changes do not affect the measurement.

Referring to FIG. 1 and FIG. 2 , the displacement sensor 12 is installed on one side of the base 11 through a fixing member (in this embodiment, the fixing member adopts bolts or screws). The displacement sensor 12 includes a contact head 121 located at its top, which can be in compression contact with the sliding mechanism 13, and a reader connected to the contact head 121 for reading the compression displacement of the contact head 122. When the grasping servo device places the microwave oven on the upper end surface of the sliding mechanism 13 and presses the microwave oven toward the reference plane, the sliding mechanism 12 moves with the microwave oven and presses the contact head 121, and the When the grasping servo device presses the microwave oven to the lower limit of the grasping servo device, the reader 122 reads the compression displacement of the contact head 121, that is, the movement of the sliding mechanism 13 relative to the reference plane displacement.

The sliding mechanism is arranged on the base 11 and moves toward the reference plane under a pressure. In this embodiment, the pressure is the pressing force of the grasping servo. Continuing to refer to FIG. 1 and FIG. 2 , the sliding mechanism 13 includes a wear plate 131 , a T-shaped block 132 , a pressing table 133 and a sliding part 134 . Wherein, the T-shaped block 132 and the pressing platform 133 form an annular space. In this embodiment, the annular space is rectangular.

The wear plate 131 is used to provide a shelf platform for the microwave oven. The grasping servo device grasps the microwave oven from the incoming material position, and places the four feet of the microwave oven to be measured on the wear-resistant plates 131 of the four auxiliary measuring devices respectively.

The T-shaped block 132 is connected to the wear-resistant plate 131 through a connecting piece (in this embodiment, the connecting piece adopts bolts or screws), and is used to support the wear-resistant plate 131 and rest on the wear-resistant plate 131. Grinding plate 131 on the microwave.

The pressing table 133 is fixed to the T-shaped block 132 through a connecting piece, and when the grasping servo device presses the microwave oven, the pressing table 133 is driven to press the contact head 121 of the displacement sensor 12 . In this embodiment, the pressing platform 133 includes: a pressing plate 133A, a first connecting plate 133B, and a second connecting plate 133C. The pressing plate 133A, the first connecting plate 133B, and the second connecting plate 133C form a concave pressing platform 133 . Wherein, the pressing plate 133A is located directly above the contact head 121 and is in contact with the contact head. The first connecting plate 133B and the second connecting plate 133C fix the pressing plate 133A to the T-shaped block 132 through the connecting pieces. In this embodiment, the lugs 111 are specifically disposed at positions corresponding to the first connecting plate 133B and the second connecting plate 133C. A second support hole for supporting the base 11 is also provided on the first connecting plate 133B and the second connecting plate 133C at positions corresponding to the first supporting hole 112 opened on the lug 111 .

The sliding portion 134 is disposed in the annular space. The sliding part 134 includes: a linear guide rail (not shown) arranged on the T-shaped block 132 to guide the T-shaped block 132 and the pressing table 133 to move toward the reference plane together; And a slider arranged on the linear guide rail and fixedly connected with the T-shaped block 132 .

The stroke adjustment block 14 is arranged on the base 11 for adjusting the upper limit of the sliding mechanism 13. There is a threaded hole at its front end, and the screw installed in the threaded hole is used to withstand the pressure plate 133A for displacement. The sensor 12 is in better contact with the pressing plate 133A, and the upper limit of the displacement sensor 12 is limited.

The elastic component 15 is used to support the first connecting plate and the second connecting plate. One end of the elastic member 15 is installed in the first supporting hole 112 , and the other end is installed in the second supporting hole. The elastic member 15 restores the sliding mechanism 12 to an uncompressed state by using the elastic force generated during the pressing process after the grasping servo device cancels the pressing operation. In this embodiment, the elastic member 15 is a spring.

The auxiliary measuring device described in this embodiment uses automatic measurement instead of manual measurement of the product to be tested, which avoids errors caused by manual measurement, and because it operates automatically, it can save a lot of time and reduce labor costs.
