Description

Technical Field

[0001] This utility model relates to the field of workpiece marking, and in particular to a workpiece rotation positioning device and an internal hole detection system. Background Technology

[0002] Some electronic devices have irregularly shaped internal holes, such as... Figure 1 As shown, the inner hole of the cylindrical device has a sharp point 100. In order to quickly find the sharp point 100 during the production process, it is often necessary to make a label hole on the outer surface of the cylindrical device so that the label hole corresponds to the position of the sharp point 100, which will facilitate subsequent processing.

[0003] The outer diameter of electronic components is generally 1cm and the inner diameter is 0.5cm. The current marking process involves the operator using a flashlight to visually observe the inner hole of the cylindrical component, find the sharp point, and then place the electronic component on a fixture to clamp it so that the sharp point is directly below the marking machine. The marking machine then punches a hole on the outer surface of the electronic component, usually using laser drilling.

[0004] The existing clamp consists of a fixed jaw and a movable jaw. During clamping, the workpiece is unsupported and suspended in mid-air. Because the electronic components of the workpiece are small, even a slight hand tremor can cause the tip to shift, requiring the clamp to be released for fine-tuning and repeated clamping. This operation is extremely cumbersome.

[0005] Therefore, it is particularly necessary to provide a device that can quickly and accurately clamp workpieces and ensure that the tip of the inner hole is located directly below the marking machine. Utility Model Content

[0006] The purpose of this utility model is to provide a workpiece rotation positioning device to address the above-mentioned problems. This workpiece rotation positioning device can quickly and accurately clamp the workpiece and ensure that the tip of the inner hole is located directly below the marking machine.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A workpiece rotation positioning device includes a base and a rotating shaft;

[0009] The base has a through-hole for mounting a rotating shaft, and the rotating shaft mounting hole is horizontally positioned.

[0010] The rotating shaft is rotatably mounted in the rotating shaft mounting hole, and both ends of the rotating shaft extend out of the rotating shaft mounting hole; one end of the rotating shaft is used to connect to the workpiece;

[0011] The substrate is also provided with a through positioning hole, which is connected to the rotating shaft mounting hole and is perpendicular to the rotating shaft mounting hole.

[0012] A positioning element is inserted into the positioning hole. When the positioning element moves toward the shaft mounting hole, it abuts against the side of the shaft to restrict the shaft from rotating.

[0013] Furthermore, the positioning element is a positioning bolt, and the positioning hole is provided with an internal thread that matches the positioning bolt.

[0014] Furthermore, a bearing is provided in the shaft mounting hole, and the shaft is mounted in the shaft mounting hole via the bearing.

[0015] Furthermore, the top of the base is an inclined surface, and the positioning hole penetrates vertically through the inclined surface and communicates with the shaft mounting hole.

[0016] Furthermore, the top of the base is provided with two inclined surfaces, which are symmetrically arranged about the vertical plane where the rotating shaft mounting hole is located. Positioning holes are provided on both inclined surfaces, and the positioning holes are symmetrically arranged about the vertical plane where the rotating shaft mounting hole is located.

[0017] Furthermore, the surface of the shaft section located within the shaft mounting hole is provided with an anti-slip structure.

[0018] Furthermore, the anti-slip structure consists of protrusions or grooves covering the entire circumference of the pivot.

[0019] This utility model also discloses an internal hole detection system, which includes a camera and the aforementioned workpiece rotation positioning device; the camera is fixedly installed next to the workpiece rotation positioning device, the lens of the camera faces the end of the rotating shaft used to connect the workpiece, and the central axis of the camera lens coincides with the central axis of the rotating shaft; the camera is connected to a controller, and a display device is connected to the controller.

[0020] Furthermore, a fill light is provided around the camera lens, and the fill light is connected to the controller.

[0021] Furthermore, the camera is mounted on the base via a camera mounting bracket, and the bottom of the base of the workpiece rotation positioning device is fixedly mounted on the base.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] The combination of the base and the rotating shaft ensures that workpieces such as electronic components are no longer suspended in the air during clamping, but are fixed on the rotating shaft, avoiding tip displacement caused by manual shaking. By inserting the positioning element into the positioning hole and abutting against the rotating shaft, the shaft position can be quickly locked, ensuring that the tip of the inner hole is accurately located in the specified position, such as directly below the marking machine. This reduces the number of repeated clamping and fine-tuning operations, improving clamping efficiency and accuracy. Attached Figure Description

[0034] A workpiece rotation positioning device includes a base 1 and a rotating shaft 2. The base 1 has a horizontally oriented rotating shaft mounting hole 101 penetrating the base 1. The rotating shaft 2 is rotatably positioned within the rotating shaft mounting hole 101, with both ends extending out of the rotating shaft mounting hole 101. One end of the rotating shaft 2 is used to connect to a workpiece. The base 1 also has a through positioning hole 102 communicating with the rotating shaft mounting hole 101 and perpendicular to the rotating shaft mounting hole 101. A positioning element 3 is inserted into the positioning hole 102. When the positioning element 3 moves towards the rotating shaft mounting hole 101, the positioning element 3 abuts against the side of the rotating shaft 2 to restrict the rotation of the rotating shaft 2.

[0035] Due to the aforementioned structure, during use, the workpiece is first installed on one end of the rotating shaft 2, and then the other end of the rotating shaft 2 is manually rotated to rotate the workpiece and fine-tune its position. After fine-tuning, the rotation of the rotating shaft 2 is restricted by the positioning component 3, thus enabling quick clamping and positioning of the workpiece and ensuring that the inner hole tip 100 is directly below the marking machine.

[0036] The combination of the base 1 and the rotating shaft 2 ensures that electronic components are no longer suspended in the air during clamping, but are fixed on the rotating shaft 2, avoiding the offset of the tip 100 caused by manual shaking. By inserting the positioning element 3 into the positioning hole 102 and abutting against the rotating shaft 2, the position of the rotating shaft 2 can be quickly locked, ensuring that the tip 100 of the inner hole is accurately located in the specified position, such as directly below the marking machine. This reduces the number of repeated clamping and fine-tuning operations, improving clamping efficiency and accuracy.

[0037] In this utility model, a workpiece mounting hole is provided at one end of the rotating shaft 2 that connects to the workpiece. The diameter of the workpiece mounting hole matches the diameter of the workpiece, making it convenient for the workpiece to be directly inserted into the workpiece mounting hole. A handwheel 4 can be installed at the other end of the rotating shaft 2 to make it easier to rotate the rotating shaft 2.

[0038] Furthermore, the positioning element 3 is a positioning bolt, and the positioning hole 102 is provided with an internal thread that matches the positioning bolt.

[0039] By screwing the bolts into and out of the positioning holes 102, the rotation of the shaft 2 can be easily restricted, and the threaded connection is reliable and provides a strong mechanical lock.

[0040] Furthermore, a bearing is provided in the shaft mounting hole 101, and the shaft 2 is mounted in the shaft mounting hole 101 through the bearing.

[0041] Without bearings, the mounting holes 101 and the shaft 2 are prone to wear, affecting clamping accuracy. The presence of bearings prevents wear, ensures clamping accuracy, and extends the equipment's lifespan.

[0042] Furthermore, the top of the base 1 is an inclined surface, and the positioning hole 102 vertically penetrates the inclined surface and communicates with the rotating shaft mounting hole 101.

[0043] The inclined design of the positioning hole 102 makes it easier to operate the bolts, reduces blind spots and errors, and improves clamping speed and accuracy.

[0044] Furthermore, the top of the base 1 is provided with two inclined surfaces, which are symmetrically arranged about the vertical plane where the rotating shaft mounting hole 101 is located. Positioning holes 102 are provided on both inclined surfaces, and the positioning holes 102 are symmetrically arranged about the vertical plane where the rotating shaft mounting hole 101 is located.

[0045] The symmetrical double-inclined surface and double positioning hole 102 design provides multi-directional operational flexibility, allowing the rotating shaft 2 to be locked from both sides, enhancing the stability and convenience of the device, and making it suitable for different operators' habits. At the same time, when bolts are inserted into the positioning holes 102 simultaneously, it ensures that the rotating shaft 2 is more securely fixed.

[0046] Furthermore, the shaft section 2 located within the shaft mounting hole 101 has an anti-slip structure on its surface.

[0047] The anti-slip structure increases the friction between the surface of the rotating shaft 2 and the positioning part 3, which can prevent the rotating shaft 2 from slipping under vibration or external force.

[0048] Furthermore, the anti-slip structure consists of protrusions or grooves covering the entire circumference of the rotating shaft 2. Example 2

[0049] This utility model also discloses an internal hole detection system, which includes a camera 7 and the aforementioned workpiece rotation positioning device; the camera 7 is fixedly installed next to the workpiece rotation positioning device, the lens of the camera 7 faces the end of the rotating shaft 2 used to connect the workpiece, and the central axis of the lens of the camera 7 coincides with the central axis of the rotating shaft 2; the camera 7 is connected to a controller, and a display device is connected to the controller.

[0050] Due to the above structure, the operator can quickly identify the tip 100 through the camera 7 and the display device without having to look at the tip 100 with the naked eye. The operation is more convenient. Just manually rotate the shaft 2 to see if the tip 100 on the display device is in the correct position.

[0051] Furthermore, a fill light is also provided around the lens of the camera 7, and the fill light is connected to the controller. The presence of the fill light ensures that the camera 7 captures clearer images.

[0052] The fill light can be a ring light consisting of several bulbs arranged in a circle around the lens.

[0053] Furthermore, the camera 7 is mounted on the base 5 via the camera mounting bracket 6, and the base 1 of the workpiece rotation positioning device is fixedly mounted on the base 5 at its bottom.

[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
