Referring to fig. 1 and 3, the present application provides a detection apparatus 100 that can be used to detect the length and concentricity of a ceramic center tube, and can also be used to detect the length and concentricity of other samples 200, which is not limited herein.

Specifically, the detecting apparatus 100 includes a base 10, a first detecting element 20 and a second detecting element 30, the first detecting element 20 is disposed on the base 10 and has a detecting slot 21 passing through, the detecting slot 21 is disposed to be in a shape of a standard of the sample 200 and has a central axis L. The second detecting element 30 includes a detecting element 31, the detecting element 31 is disposed on the base 10 and located at one end of the first detecting element 20 in the direction of the central axis L, the detecting element 31 has a second end surface 312, the first detecting element 20 has a third end surface facing the second end surface 312, a reserved space extending along the direction of the central axis L is provided between the second end surface 312 and the third end surface 23, and the detecting groove 21 is communicated with the reserved space.

Thus, on the one hand, when the sample 200 is placed in the detection groove 21 which is arranged in a copying manner with the sample 200, if the concentricity of the sample 200 is poor, the sample cannot smoothly enter the detection groove 21, so that the control on the concentricity of the sample 200 is realized.

Concentricity is the degree of center offset, and is a special form of coaxiality. When the measured element is the circle center (point), the hole on the thin workpiece or the axis of the shaft, the measured axis is regarded as the measured point, and the coaxiality of the measured axis and the hole on the thin workpiece to the reference axis is the concentricity. Through the control to the concentricity of the sample 200, the yield of the sample 200 can be ensured.

On the other hand, by providing the reserved space between the second end surface 312 and the third end surface 23, which is equivalent to forming a reserved tolerance, when the sample 200 penetrates from one side of the detection slot 21 and just fills the detection slot 21, it indicates that the length of the sample 200 is just equal to the length of the detection slot 21, and the length of the sample 200 just meets the standard length. If one end of the sample 200 passes out of the detection slot 21 through the third end surface 23 and into the reserved space, it indicates that the length is within the reserved tolerance. Thereby enabling control of the length of the sample 200.

It is understood that the detection slot 21 has a first preset length in the direction of the central axis L, the second end surface 312 and the third end surface 23 have a second preset length in the direction of the central axis L, and the sum of the first preset length and the second preset length is the longest limit length. When the sample 200 exceeds this maximum limit length, it indicates that the sample 200 is too long and does not meet the standard. And, the first predetermined length is the shortest limit length, and when the sample 200 is shorter than the shortest limit length, that is, the sample 200 cannot fill the detection slot 21, it indicates that the sample 200 is too short and does not meet the standard requirement.

In practical applications, the detection apparatus 100 provided in the present application can be applied to the end of a production line to detect whether the concentricity and the length of the sample 200 generated by a certain production line meet the set requirements. When the sample 200 cannot be loaded into the detection slot 21, or the sample 200 cannot pass through the detection slot 21 (i.e., the sample 200 cannot be plugged into the detection slot 21), or the sample 200 has already abutted against the second end surface 312, a portion of the sample still does not enter the detection slot 21, which is indicated as a defective product and is not satisfactory.

Further, the second end face and the third end face are arranged in parallel, so as to ensure

In one embodiment, the detection slot 21 is symmetrically disposed with respect to the central axis L, that is, in the extending direction of the detection slot 21, the geometric centers of all positions are located on the central axis L, so as to ensure good concentricity of the detection slot 21. Naturally, if the concentricity of the detection groove 21 provided in accordance with the outer appearance profile of the sample 200 is good, the detected concentricity of the sample 200 satisfying the requirement is also good. When the sample 200 cannot be completely inserted into the detection groove 21 to a predetermined degree, it indicates that the concentricity is not satisfactory.

In one embodiment, the test slot 21 extends in a step-like manner along the central axis L, thus accounting for the length and concentricity arrangement of the sample 200 with the step-like appearance, as shown in fig. 1. At this time, if the length and the concentricity of the partial segment need to be measured, the partial segment cannot be clamped by a ruler or other measuring tools, and one end of the partial segment does not have a fixed foundation. At the moment, the detection groove 21 is matched with the detection groove 21 which is required to be partially and sectionally profiled, and a reserved space is arranged to be used as a reserved tolerance, so that the sample 200 meeting the requirement is screened out, and the method is simple, convenient and low in cost. In other embodiments, the detection slot 21 may be configured in other shapes, which is not limited herein.

In one embodiment, the first detecting element 20 has a first end surface 22 opposite to the third end surface 23, the detecting groove 21 penetrates through the first end surface 22 and the third end surface 23, the first end surface 22 and the third end surface 23 are both perpendicular to the central axis L, a direction from the first end surface 22 to the third end surface 23 is an assembling direction of the first detecting element 20, and the sample 200 enters the detecting groove 21 from one side of the first end surface 22 and can pass out from one side of the third end surface 23 and enter the reserved space. When the sample 200 enters the detection slot 21 from one side of the first end surface 22 to abut against the first end surface 22, the other end is flush with the third end surface 23 or passes out of the third end surface 23 and enters the reserved space, which is qualified.

It can be understood that the sample 200 is qualified as long as one end of the sample 200 abuts against the first end surface 22 and the other end enters the headspace, and when the length of the sample 200 reaches the maximum limit length, the end entering the headspace can abut against the second end surface 312, so as to form a limit condition that one end abuts against the first end surface 22 and the other end abuts against the second end surface 312.

In order to know the length of the sample 200 more precisely, the detecting device 31 is further configured to detect the remaining length of the end of the sample 200 facing the second end surface 312 and the third end surface 23 in the direction of the central axis L, the detecting apparatus 100 further includes a display element 32, the display element 32 is configured to display the remaining length, and the remaining length plus the first preset length of the detecting groove 21 in the direction of the central axis L is the actual length of the sample 200. Thereby allowing the operator to visually obtain data from the display 32 to calculate the final length of each sample 200.

Optionally, the display unit 32 is a data table, which can acquire the data detected by the detecting unit 31 and visually display the data to the user.

In one embodiment, the position of the detecting tool 31 and/or the first detecting member 20 in the direction of the central axis L relative to the base 10 is variable. That is, the size of the reserved space between the detection device 31 and the first detection component 20 is adjustable, and when the detection device is used, the position of the detection device 31 and/or the first detection component 20 on the base 10 can be adjusted according to engineering requirements, so that the size of the reserved space, that is, the size of the reserved tolerance, is changed, and the detection device 100 provided by the application can meet various requirements.

In one embodiment, the detecting apparatus 100 further includes a fixing member 40, the fixing member 40 and the display member 32 are disposed on the base 10, and the display member 32 includes a connecting portion 321, and the connecting portion 321 passes through the fixing member 40 and is detachably connected to the detecting device 31. Therefore, all the structures are integrated on the base 10, the display part 32 and the detection part 31 are connected to form a whole through the fixing part 40, and the position on the base 10 is adjustable.

Specifically, the detecting tool 31 has a fixing groove 311, and the connecting portion 321 passes through the fixing member 40 and is disposed in the fixing groove 311, so as to connect the display element 32 and the detecting tool 31.

In one embodiment, the detecting apparatus 100 further includes a fastening element 50, the fastening element 50 is used to fix the connecting portion 321 on the fixing element 40, when the position of the detecting device 31 needs to be adjusted, the fastening element 50 is removed, and after the position of the connecting portion 321 is adjusted to drive the detecting device 31 to move to a target position, the fastening element 50 is installed. Alternatively, the fastener 50 may be a bolt or other structure, and similarly, the fastener 50 may be used to detachably mount the first detecting member 20 to the base 10.

This check out test set 100 not only uses in the high management and control of ceramic center post, can extend moreover in the high management and control of each product, and the concentricity management and control demand, the practicality is strong and simple structure.

For example, if the length of the detection groove 21 in the direction of the central axis L is 39.6mm and the length of the headspace in the central axial direction is 1mm, it is acceptable if the length of the sample 200 is 40.6mm or less and 39.6mm or more, and if the length is 40.65mm or less and 39.6mm or more, in consideration of the error. If the indicator 32 indicates 0.86mm after one of the samples 200 is loaded in the test chamber 21, the sum of the lengths of the samples 200, which is 39.6mm and 0.86mm, is 40.46mm, and the sample is judged to be acceptable.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several implementation modes of the present application, and the description thereof is specific and detailed, but not construed as limiting the scope of the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
