Description

Technical Field

[0001] The utility model relates to the technical field of workpiece detection, in particular to a conical hole depth detection device. Background Art

[0002] The conical hole depth detection device is a precision measuring tool for measuring the depth of conical holes on workpieces. This device can improve the accuracy and efficiency of conical hole measurement, which is crucial for ensuring the machining quality of mechanical parts; the conical hole depth detection device is applicable to various occasions that require precise measurement of conical hole depth, such as mechanical processing, automobile manufacturing, aerospace, mold manufacturing and other industries. Precision components in these industries often require strict dimensional tolerances and shape accuracies, so an efficient and accurate detection device is particularly important.

[0003] When detecting the depth of conical holes of some existing cylindrical workpieces, it is mostly relied on workers to insert a measuring ruler into the conical hole for measurement. However, when the measuring ruler is inserted into the conical hole, it is impossible to ensure that the measuring ruler is in the center position of the conical hole, resulting in the measuring ruler being prone to tilt, thus affecting the accuracy of the measurement and detection work of the conical hole depth.

[0004] To solve the above problems, we propose a conical hole depth detection device to solve the above problems. Content of the Utility Model

A measuring rod is movably installed in the middle of the inner side of the clamping seat, and a scale is arranged on the outer surface of the measuring rod; a clamping assembly is arranged at the bottom end of the clamping seat. The clamping assembly includes three groups of clamps. A clamping block is arranged in the middle of the inner side of the clamp. The clamping block is movably installed in the middle of the inner side of the clamp. The clamping surface of the clamping block is set as an arc structure. A spring is arranged in the middle of the back of the clamping block. Among them, the clamping seat can be clamped and fixed at the head end of the workpiece through the three groups of clamps, then the measuring rod is pushed into the conical hole, and then by observing the scale, the measurement and detection work of the depth of the conical hole can be realized.

[0008] Preferably, an installation cylinder is arranged at the outer end of the clamp. The head end of the spring is installed in the middle of the inner side of the installation cylinder.

[0021] The technical solution in the embodiment of the present application to solve the problems in the above-mentioned background technology is generally as follows: In the utility model, a measuring rod 2 is movably installed in the middle of the clamping seat 1, and a scale 21 is engraved on the surface of the measuring rod 2. By clamping and installing the clamping seat 1 at the head end of the workpiece, and then pushing the measuring rod 2 into the tapered hole, the rapid measurement and detection of the depth of the tapered hole of the cylindrical workpiece can be realized. In addition, the setting of the three groups of jigs 3 can improve the installation stability of the clamping seat 1, make the measuring rod 2 in the center position of the tapered hole, avoid the deviation of the measuring rod 2 during the measurement work, and thus effectively improve the accuracy of the measuring rod 2 for measuring and detecting the depth of the tapered hole.

[0022] Embodiment: Refer to Figure 1 - Figure 4 As shown, a tapered hole depth detection device in this embodiment includes a clamping seat 1. A measuring rod 2 is movably installed in the middle of the inner side of the clamping seat 1, and a scale 21 is arranged on the outer surface of the measuring rod 2. The setting of the scale 21 facilitates the staff to observe the length of the measuring rod 2 inserted into the tapered hole, so as to calculate the depth of the tapered hole.

[0023] A clamping component is arranged at the bottom end of the clamping seat 1. The clamping component includes three groups of jigs 3. A clamping block 31 is arranged in the middle of the inner side of the jig 3. The clamping block 31 is movably installed in the middle of the inner side of the jig 3. The clamping surface of the clamping block 31 is set as an arc structure, and a spring 33 is arranged in the middle of the back of the clamping block 31.

[0024] Among them, under the action force generated by the spring 33, when the clamping block 31 is pushed by an external force, the clamping block 31 will slide towards the inner side of the jig 3. At the same time, through the push of the spring 33, the clamping block 31 can clamp the outer surface of the workpiece, so as to install the clamping seat 1 at the head end of the workpiece.

[0025] And, a circular groove 11 is arranged in the middle of the bottom end of the clamping seat 1. The three groups of jigs 3 are distributed in a triangle on the bottom end surface of the clamping seat 1 and are arranged on the periphery of the groove 11.

[0026] Among them, the jigs 3 distributed in a triangle have stability, can improve the stability of the clamping seat 1 during installation, and also make the measuring rod 2 in the center position of the tapered hole, thereby improving the accuracy of measuring the depth of the tapered hole.

[0027] An installation cylinder 32 is arranged at the outer end of the jig 3. The installation cylinder 32 is threadedly connected to the jig 3. The head end of the spring 33 is installed in the middle of the inner side of the installation cylinder 32. The setting of the installation cylinder 32 facilitates the staff to maintain or replace the spring 33.

[0028] In some examples, a limiting rod 34 is provided on the back of the clamping block 31, and the end of the spring 33 is sleeved around the periphery of the limiting rod 34. The setting of the limiting rod 34 improves the stability of the clamping block 31 when sliding.

[0029] In some examples, limiting blocks 35 are provided at both bottom ends of the clamping block 31. The limiting blocks 35 are movably installed at both inner ends of the fixture 3. The limiting blocks 35 play a role in limiting, improve the stability of the clamping block 31 when sliding, and also prevent the clamping block 31 from falling off the fixture 3.

[0030] In some examples, an upper limiting ring 22 is provided at the top of the measuring rod 2, and a lower limiting ring 23 is provided at the bottom of the measuring rod 2. Both the upper limiting ring 22 and the lower limiting ring 23 play a role in limiting, preventing the measuring rod 2 from falling off the clamping seat 1.

[0031] The working principle of the present utility model is as follows:

[0032] When it is necessary to detect the taper hole depth of a cylindrical workpiece, first insert the head end of the workpiece to be detected into the groove 11 at the base of the clamping seat 1. During the insertion process, the workpiece will push the three groups of clamping blocks 31. Under the elastic force of the spring 33, the clamping blocks 31 will slide inwardly towards the inner side of the fixture 3 under the force. When the workpiece is completely inserted, at this time, the three groups of clamping blocks 31 can clamp and fix the head end of the workpiece from the triangular direction, thereby maintaining the stability of the clamping seat 1;

[0033] Then manually push the measuring rod 2 until the bottom end of the measuring rod 2 is inserted into the bottom of the taper hole of the workpiece. At this time, by observing the scale 21 on the surface of the measuring rod 2, the measurement and detection of the depth of the taper hole can be realized.

[0034] With the above structure, the present utility model facilitates the staff to quickly measure and detect the depth of the taper hole of the cylindrical workpiece. And during the detection process, the three groups of fixtures 3 clamp and fix the head end of the workpiece, thereby improving the stability of the clamping seat 1, making the measuring rod 2 in the center position of the taper hole, and effectively improving the accuracy of the measuring rod 2 for measuring and detecting the depth of the taper hole.
