Description

Technical Field

[0001] This utility model belongs to the field of cone ring irregular inclined hole detection, and particularly relates to a cone ring irregular inclined hole detection device. Background Technology

[0002] Conical rings with irregular oblique holes are widely used in various fields, such as... Figure 1 As shown, the inner wall of the conical ring irregular oblique hole a is a conical structure. Three fracture grooves a1 are evenly distributed along the circumference of the side wall of the conical ring irregular oblique hole a. Each of the three fracture grooves a1 has an oblique hole a2 opening inwards in the same direction. A slot hole a3 is formed on the conical ring irregular oblique hole a corresponding to each fracture groove a1, and a positioning hole a4 is formed between two adjacent slot holes a3.

[0003] Existing inspection methods typically utilize depth measuring tools, such as graduated measuring rods. During inspection, the tool is inserted into each angled hole one by one according to requirements, and the reading is taken after the measuring rod touches the bottom. While this method can detect the depth of angled holes, the process is cumbersome and prone to missed detections, resulting in defective parts being released. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a tapered ring irregular oblique hole detection device, which aims to solve the problem that the detection process of the existing tapered ring irregular oblique hole detection device is relatively troublesome and prone to missed detection, resulting in the outflow of unqualified parts.

[0005] The present invention adopts the following technical solution:

[0006] The tapered ring irregular inclined hole detection device includes a machine base, a detection seat on the machine base, and multiple sets of detection mechanisms evenly arranged around the detection seat on the machine base. Each detection mechanism includes a fixed seat mounted on the machine base, a slide seat on the fixed seat, a displacement sensor on the slide seat, the contact end of the displacement sensor facing the detection seat, and a digital display on the displacement sensor. A sliding cylinder is provided on the fixed seat, and the drive shaft of the sliding cylinder is connected to the slide seat.

[0007] Furthermore, the detection seat includes a circular base, a limiting frustum on the circular base, and a positioning post on the circular base.

[0008] Furthermore, the circular base has a pair of clearance openings.

[0009] Furthermore, the top surface of the slide has a limiting opening, and two rows of fixing threaded holes are provided in the limiting opening. A matching connecting seat is provided in the limiting opening, and the displacement sensor is connected to the connecting seat. A pair of oval grooves are provided on the connecting seat, and a fixing nut is inserted into the oval groove. The bottom of the locking nut is screwed into the fixing threaded hole.

[0010] Furthermore, the side wall of the connecting seat has a split groove and a circular groove sequentially from the outside to the inside, and the split groove and the circular groove are connected. A pair of locking nuts are screwed into the top of the connecting seat corresponding to the split groove.

[0011] Furthermore, limit sensors are provided at both the front and rear positions of the fixed base.

[0012] The beneficial effects of this utility model are as follows: When using this device to inspect the irregular oblique hole of the conical ring, first install the irregular oblique hole of the conical ring on the detection seat as required, with all displacement sensors in their initial positions. Press the detection switch, and the sliding cylinder will work simultaneously. The displacement sensors will move toward the oblique hole on the same side. When the contact end contacts the bottom of the oblique hole, the depth of the oblique hole is obtained and displayed on the digital display. The result is judged. If it is not qualified, the alarm will sound, and at the same time, the sliding cylinder will stop working and drive the displacement sensor to reset to the initial position, so that the current part can be removed.

[0017] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0019] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0020] Combination Figure 2-4As shown, the tapered ring irregular oblique hole detection device includes a machine base 1, on which a detection seat 2 is provided. Multiple detection mechanisms are evenly arranged around the detection seat on the machine base 1. Each detection mechanism includes a fixed base 3 mounted on the machine base 1, a slide 4 on the fixed base 3, and a displacement sensor 5 on the slide 4. The contact end of the displacement sensor 5 faces the detection seat, and the displacement sensor 5 has a digital display 6. A sliding cylinder 7 is provided on the fixed base 3, and the drive shaft of the sliding cylinder 7 is connected to the slide 4. Limit sensors 8 are provided at both the front and rear positions of the fixed base 3 to limit the distance the slide moves.

[0021] like Figure 1 As shown, the inner wall of the conical ring irregular oblique hole a is a conical structure. Three fracture grooves a1 are evenly formed along the circumferential direction on the side wall of the conical ring irregular oblique hole a. Each of the three fracture grooves a1 has an oblique hole a2 forming an inward-facing hole in the same direction. A slot hole a3 is formed on the conical ring irregular oblique hole a corresponding to each fracture groove a1, and a positioning hole a4 is formed between two adjacent slot holes a3. After the conical ring irregular oblique hole is manufactured, this device can be used to simultaneously perform depth detection on the three oblique holes within the conical ring irregular oblique hole.

[0022] In this embodiment, an alarm is also provided on the machine base, and the alarm is electrically connected to three displacement sensors. When using this device to inspect the tapered ring with an irregularly shaped inclined hole, the tapered ring with the irregularly shaped inclined hole is first installed on the detection seat as required, with all displacement sensors in their initial positions. Then, the detection switch 15 is pressed, and the three sliding cylinders work simultaneously, moving the displacement sensors toward the inclined holes on the same side. The contact end of the displacement sensor is inserted into the inclined hole until it contacts the bottom of the inclined hole, and the depth of the inclined hole is obtained and displayed on the digital display. The result is then judged. If it is not qualified, the alarm sounds. At the same time, the sliding cylinders stop working and drive the displacement sensors back to their initial positions, allowing the current part to be removed.

[0023] In practice, when the displacement sensor is in its initial position, the distance between the sensor's contact end and the oblique hole port on the same side is constant. When measuring the oblique hole depth using the displacement sensor, the sensor moves from its initial position toward the oblique hole on the same side until its contact end touches the bottom of the hole. At this point, the digital display records the distance the sensor has moved minus the constant value, thus obtaining the oblique hole depth. The result is then judged, and an alarm is triggered if the result is unqualified. This allows the device to simultaneously detect the depth of three oblique holes on a part, saving time and effort, increasing efficiency, and preventing missed detections. Since the displacement sensor is existing technology, it will not be described in detail here.

[0024] As a specific structure, such as Figure 2The detection seat 2 includes a circular base 21, on which a limiting frustum 22 and a positioning post 23 are provided. Before placing the conical ring with its irregular oblique hole onto the detection seat, the part is positioned vertically relative to the detection seat. The part is then adjusted until a positioning hole on the part is aligned vertically with the positioning post. Finally, the part can be placed on the detection seat. After the part is placed, it rests on the circular base, with the limiting frustum located on the inner wall of the conical ring with its irregular oblique hole, and the positioning post located within the positioning hole. The positioning post and the limiting frustum prevent the part from rotating, and the limiting frustum matches the inner wall of the conical ring with its irregular oblique hole.

[0025] In the above process, after the part is placed on the detection seat as required, the three oblique holes of the part are aligned with the contact ends of the three displacement sensors. Then, the three displacement sensors can simultaneously move towards the three oblique holes under the drive of their corresponding sliding cylinders to detect the depth of the oblique holes.

[0026] In addition, the circular base 21 has a pair of clearance openings 24. The clearance openings make it more convenient to pick up and put down parts.

[0027] As a preferred structure, such as Figure 3-4 The top surface of the slide block 4 has a limiting port 9, and two rows of fixing threaded holes 10 are opened in the limiting port 9. A matching connecting seat 11 is provided in the limiting port 9. The displacement sensor 5 is connected to the connecting seat 11. A pair of oval grooves 12 are opened on the connecting seat 11. A fixing nut (not shown in the figure) is inserted into the oval groove 12. The bottom of the locking nut is screwed into the fixing threaded hole.

[0028] The detection seat is fixed to the machine base by a mounting nut. When using this device to detect conical rings with irregular oblique holes of different sizes, only the corresponding detection seat needs to be replaced. After changing to a different detection seat, the installation position of the displacement sensor needs to be readjusted to ensure that the contact end of the displacement sensor always corresponds one-to-one with the oblique hole of the part after the part is installed on the detection seat.

[0029] In this structure, the displacement sensor is mounted on the slide block via the connecting seat. The slide block has a limiting port, within which the connecting seat is placed. In practice, the position of the displacement sensor can be adjusted by changing the mounting position of the connecting seat to accommodate parts of different specifications. Specifically: first, loosen the fixing nut, allowing the connecting seat to slide within the limiting port, moving the displacement sensor accordingly until it aligns with the corresponding oblique part. Finally, tighten the fixing nut, screwing its end into the corresponding threaded hole. Because the width of the connecting seat matches the width of the limiting port, the limiting port effectively limits the position of the connecting seat.

[0030] In addition, such as Figure 4 The side wall of the connecting seat 11 has a split groove 13 and a circular groove 14 sequentially from the outside to the inside, and the split groove 13 and the circular groove 14 are connected. A displacement sensor 5 is inserted into the circular groove 14, and a pair of locking nuts are screwed into the top of the connecting seat 11 corresponding to the split groove 13.

[0031] In this structure, the displacement sensor is mounted on the connector. To remove the displacement sensor from the connector, simply unscrew the two locking nuts, and then move the displacement sensor backward until it detaches from the connector. The displacement sensor is detachable, facilitating future maintenance, repair, and replacement.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
