Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of component detection; specifically, the utility model relates to a hole position detection device. Background Art
[0002] Automobile flywheels are generally processed and shaped by stamping, hot pressing and other methods, and processed by CNC machining centers for drilling and reaming. In order to ensure the quality of the flywheel, it is often necessary to conduct hole position inspection on the flywheel after processing to avoid problems such as missing holes and hole deviations.
[0003] The traditional hole position detection method is to detect the hole position through three-coordinate, which is only suitable for the first sample detection and random inspection of product processing; it also requires a specific room with relatively constant temperature and humidity for storage, and there is no external environmental factors such as vibration source and noise. It is not suitable for batch production detection at the processing site. This limits the detection efficiency during the workpiece production process and cannot meet high-load production tasks at all.
[0004] In the modern engineering field, digital tools are becoming more and more popular and mature, such as computer-aided design tools and 3D modeling tools. Hole positioning detection is applied to actual machines in a digital way. However, the cost of dedicated high-tech equipment is relatively high, which increases the processing cost of accessories.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a hole position detection device, wherein the hole position detection device comprises: a bottom plate and a detection pin,
[0007] The detection pin comprises a pin body and a pin head, and the pin head is used to detect the hole position of the tested object;
[0008] The bottom plate is provided with a positioning hole, the positioning hole is used to insert a pin body, and there is an interference fit between the positioning hole and the pin body.
[0009] In the hole position detection device as described above, optionally, the diameter of the pin head is smaller than the diameter of the corresponding hole position of the measured object.
[0010] In the hole position detection device as described above, optionally, the top of the pin head is an upwardly contracted structure.
[0011] In the hole position detection device as described above, optionally, the positioning hole located at the center position of the base plate is a center positioning hole, and the detection pin is provided with a center positioning pin corresponding to the center positioning hole.
[0012] In the hole position detection device as described above, optionally, the upper portion of the center positioning pin is in the shape of a triangular prism, three upper edges of the center positioning pin are chamfered, and beveled surfaces are provided on the upper portions of the three edges.

[0016] According to the hole position detection device of the utility model, the worker places the workpiece to be tested on the upper end surface of the bottom plate, aligns the center hole of the flying disc with the center positioning hole, and aligns the holes to be tested with the corresponding detection pins. If all the detection pins can penetrate into the corresponding holes to be tested downward, it means that the hole position of the flying disc is accurate. If they cannot be penetrated smoothly, it means that there is a quality problem with the hole position of the flying disc. The worker can quickly complete the detection of all hole positions of the workpiece to be tested, thereby improving the detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] It should be noted that, in the description of the present invention, the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. The terms "first", "second" and similar words used in the description of the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components, and therefore cannot be understood as limitations on the present invention.
[0023] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.
[0024] It should be noted that like reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined or described in one drawing, it will not require further detailed discussion and description in the description of the subsequent drawings.
[0025] like Figures 1 to 3 The figure shows the bottom plate and the detection pin of the hole position detection device of the utility model and its structural schematic diagram when used.
[0026] The detection pin comprises a pin body 1 and a pin head 2.
[0027] Furthermore, a positioning hole 3 is provided on the bottom plate for inserting the pin body 1, and there is an interference fit between the two.
[0028] The pin head 2 is used to detect the hole position of the measured object 4. Preferably, the diameter of the pin head 2 is smaller than the diameter of the corresponding hole position of the measured object 4.
[0029] Since the detection pin is detachable, detection pins with different pin heads 2 can be replaced to detect different test pieces 4, and for test pieces 4 with different apertures, detection pins with pin heads 2 of different sizes can be replaced to meet various needs.
[0030] Furthermore, the top of the pin head 2 is an upwardly contracted structure.
[0031] Specifically, in this embodiment, the difference between the diameter of the pin head 2 and the diameter of the corresponding hole of the measured object 4 is about 0.1 mm.
[0032] Furthermore, the positioning hole 3 at the center position of the bottom plate is provided with a center positioning hole 5 , and the corresponding detection pin is a center positioning pin 6 . The center positioning pin 6 is embedded in the center positioning hole 5 to locate the center hole of the test piece 4 .
[0033] In this embodiment, the lower portion of the center positioning pin 6 is inserted into the center positioning hole 5 by interference fit, and the upper portion of the center positioning pin 6 is in the shape of a triangular prism, with three edges chamfered and beveled surfaces provided on the upper portions of the three edges.
[0034] Furthermore, the bottom plate is provided with a plurality of fixing holes 7 for fixing to the processing table using fasteners such as bolts, and the corresponding processing table is provided with threaded holes (the processing table and bolts are not shown in the figure).
[0035] Specifically, in this embodiment, the center positioning hole 5 and the fixing hole 7 are countersunk holes.
[0036] Furthermore, in order to reduce the deadweight of the hole position detection device, a plurality of arc grooves 8 are provided on the outer side of the bottom plate, and a plurality of through holes 9 are provided inside the bottom plate. Such a design can also reduce the stress of the bottom plate itself and prevent the bottom plate from deforming.
[0037] like Figure 3 As shown, when in use, the hole position detection device is fixed on the processing table by bolts passing through the fixing holes 7, and the detection pins (including the center positioning pins 6) are inserted into the corresponding positioning holes 3, and then the center hole of the flying disc is aligned with the center positioning hole 5, and the holes to be measured are aligned with the corresponding detection pins. If all the detection pins can penetrate into the corresponding holes to be measured downward, it means that the hole position of the flying disc is accurate. If they cannot be penetrated smoothly, it means that there is a quality problem with the hole position of the flying disc.
[0038] After the detection is completed, the flying disc is removed from the detection pin, and the next detection can be carried out. Because the outer side of the base plate is provided with a plurality of arc grooves 8, when removing the flying disc, it is convenient for fingers to take the flying disc.
[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
