[0008] In a preferred embodiment of the tap positioning detection device of this utility model, the number of taps is several, the number of mounting rods is two, and a sensor is fixed to the bottom of the tap.

[0009] In a preferred embodiment of the tap positioning detection device of this utility model, a guide rod is fixed to the bottom of the lower pressure plate, and the number of the guide rods is several.

[0010] As a preferred embodiment of the tap positioning detection device of this utility model, a first compression spring is sleeved on the surface of the guide rod, one end of the first compression spring is fixed to the surface of the guide rod (133), and the other end of the first compression spring is fixed to the bottom of the lower pressure plate.

[0017] The beneficial effects of this utility model are as follows: Through the installation and ejection components, the displacement groove and the guide block of the displacement plate form a limiting guide. When the second compression spring is damaged after prolonged use or its elasticity fails, the screw thread adjusts the displacement plate. At this time, the displacement plate moves upward, simultaneously pressing against several second compression springs, thereby causing the ejection rod to move upward synchronously. This allows the top of the ejection rod to contact the bottom of the sunroof guide rail body, thus ejecting the sunroof guide rail body. When it is necessary to replace the second compression spring, the working... The storage shell is manually rotated counterclockwise, causing the rotating column to rotate synchronously. The rotating column rotates within the rotating groove. When the rotating groove matches the placement groove, the entire storage shell can be removed. Compared to the traditional manual removal method, manual removal requires the operator to insert their hand into the testing device and get close to the lower pressure plate and tap components, posing a safety hazard of being squeezed or scratched. In addition, uneven force applied by the operator, fingertip contact, or tool prying can easily cause surface scratches, damage to threaded holes, or slight deformation of the car sunroof guide rail body, which may directly affect the assembly accuracy of the car sunroof guide rail body.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a tap positioning detection device, which includes an installation component 1 and an ejection component 2. During the inspection of automotive sunroof guide rail products, the products have threaded holes that are responsible for the overall assembly and fixation with the sunroof. It is easy for the tap to miss the tapping thread. Therefore, a sensor is added below the tap. The tap must sink to the specified position before the next production can proceed. If the tap does not reach the required position, the sensor will not detect it and the machine will alarm.

[0030] Specifically, the mounting assembly 1 includes a mounting plate 11, a mounting rod 12 fixed to the top of the mounting plate 11, a lower pressure plate 13 slidably sleeved on the surface of the mounting rod 12, a tap 131 fixed to the bottom of the lower pressure plate 13, a hydraulic cylinder 14 fixed to the top of the lower pressure plate 13, and a pre-pressing positioning component 132 fixed to the bottom of the lower pressure plate 13.

[0031] Specifically, the ejector assembly 2 is disposed on the top of the mounting plate 11, including a clamping and fixing plate 21 fixed to the top of the mounting plate 11, a car sunroof guide rail body 23 is disposed on the top of the clamping and fixing plate 21, a displacement plate 22 is disposed inside the clamping and fixing plate 21, a screw 221 is threadedly connected to the surface of the displacement plate 22, and an ejector 24 is disposed on the top of the displacement plate 22.

[0032] With the installation plate 11, the installation plate 11 serves as the basic load-bearing component of the device, providing a rigid fixed support point for the installation rod 12 and the ejector assembly 2, ensuring the positional accuracy of the upper and lower components, and preventing misalignment of the tap 131 and the workpiece due to foundation deformation. With the installation rod 12, the two symmetrically distributed installation rods 12 form a sliding guide structure, constraining the movement trajectory of the pressure plate 13, preventing it from tilting or shifting during its up and down movement, and ensuring that the tap 131 is vertically aligned with the threaded hole.

[0033] By setting the pressure plate 13, several taps 131 are driven to press down synchronously under the driving force, ensuring that multiple threaded holes of the car sunroof guide rail body 23 are inspected at the same time, greatly improving the efficiency of batch inspection and avoiding the time-consuming problem of single-hole inspection.

[0034] Example 2, refer to Figures 2-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, there are several taps 131, two mounting rods 12, and a sensor 135 is fixed to the bottom of the tap 131.

[0036] Specifically, a guide rod 133 is fixed to the bottom of the lower pressure plate 13, and there are several guide rods 133.

[0037] Specifically, a first compression spring 134 is sleeved on the surface of the guide rod 133. One end of the first compression spring 134 is fixed to the surface of the guide rod 133, and the other end of the first compression spring 134 is fixed to the bottom of the lower pressure plate 13.

[0038] The tap 131 is designed to correspond to the thread hole specifications of the sunroof guide rail body 23. The integrated sensor 135 at its bottom prevents the problem of missing taps from the source. The pre-pressing positioning component 132 is used to pre-position and slightly press the sunroof guide rail body 23 before the tap 131 contacts the workpiece, preventing the workpiece from shifting when the tap 131 is pressed down, and ensuring the accuracy of the alignment between the thread hole and the tap 131.

[0039] By setting the guide rod 133, the movement trajectory of the lower pressure plate 13 is further constrained, so that the straightness error of the tap 131 pressing trajectory is controlled within a very small range, which is suitable for the thread hole inspection requirements. By setting the first compression spring 134, elastic buffering is provided when the tap 131 contacts the workpiece, avoiding the tap 131 from breaking or the workpiece thread hole from hard contact, and extending the service life of the core components.

[0040] By setting up the sensor 135, it can directly detect whether the tap 131 has sunk to the specified position. The signal feedback enables real-time judgment of whether it is qualified or unqualified, solving the problem of missing tapping. By setting up the clamping and fixing plate 21, it provides a placement plane and positioning boundary for the car sunroof guide rail body 23, ensuring the consistency of the installation position of the car sunroof guide rail body 23 each time and reducing the detection error caused by placement deviation.

[0041] Specifically, the surface of the clamping and fixing plate 21 is provided with a displacement groove 211, and the top of the displacement plate 22 is fixed with a guide block 223.

[0042] Specifically, the top of the guide block 223 is fixed to the top of the displacement groove 211, and the bottom of the screw 221 is fixed with an anti-slip torsion block 222.

[0043] Specifically, the ejector 24 includes a mounting base 241 fixed to the top of the displacement plate 22, and there are several ejector 24s.

[0044] Specifically, the mounting base 241 has a rotating groove 2411 inside, the rotating groove 2411 has a placement groove 2412 inside, and the top of the mounting base 241 is provided with a storage shell 242.

[0045] Specifically, a rotating column 2421 is fixed to the bottom of the storage shell 242, the rotating column 2421 is located in the inner cavity of the rotating groove 2411, and a second compression spring 243 is fixed inside the storage shell 242.

[0046] Specifically, a push rod 244 is fixed to the top of the second compression spring 243, and the top of the push rod 244 contacts the bottom of the car sunroof guide rail body 23.

[0047] By setting the displacement groove 211, a sliding fit is formed with the guide block 223, which restricts the movement direction of the displacement plate 22 and ensures that the displacement plate 22 can only rise and fall in the vertical direction, avoiding uneven ejection force caused by tilting. By setting the displacement plate 22, when the elasticity of the second compression spring 243 decays or fails, the displacement plate 22 can realize synchronous height compensation for multiple ejector parts 24 by its own rising and falling, and the ejection function can be restored without immediately replacing the second compression spring 243.

[0048] By setting the screw 221, the displacement plate 22 can be slightly raised and adjusted through the threaded transmission. The ejection height can be controlled according to the degree of failure of the second compression spring 243, ensuring reliable contact between the ejection rod 244 and the bottom of the car sunroof guide rail body 23. The anti-slip torsion block 222 increases the hand grip contact area and friction, making it easier for staff to quickly complete the rotation adjustment of the screw 221 and reducing the difficulty of maintenance operations.

[0049] With the mounting base 241, the combination design of the rotating groove 2411 and the placement groove 2412 provides a mechanical interface for quick disassembly and assembly of the storage shell 242. It is the core structure for convenient replacement of the second compression spring 243. With the rotating groove 2411, the rotating groove 2411 provides a circumferential motion trajectory and radial positioning for the rotating column 2421, ensuring reliable installation of the storage shell 242 and preventing the storage shell 242 from falling off due to vibration during operation.

[0050] By setting the placement slot 2412, when the rotating column 2421 rotates to align with the placement slot 2412, the placement slot 2412 forms the axial placement and removal of the storage shell 242, realizing tool-free quick disassembly of the storage shell 242 and greatly shortening the replacement time of the second compression spring 243.

[0051] By setting the housing 242, the housing 242 forms a closed protection for the second compression spring 243, preventing metal shavings and oil stains generated during processing from entering the spring gap, avoiding jamming or corrosion of the second compression spring 243, and extending its service life. By setting the ejector rod 244, the elastic force of the second compression spring 243 or the thrust of the displacement plate 22 is evenly transmitted to the bottom of the car sunroof guide rail body 23, avoiding surface damage caused by direct contact between the spring and the workpiece.

[0052] In use, first, the car sunroof guide rail body 23 to be tested is placed on top of the clamping and fixing plate 21. The clamping and fixing plate 21 provides a positioning reference for the workpiece. The pre-pressing positioning component 132 moves down with the lower pressure plate 13 to pre-position and press the car sunroof guide rail body 23 to avoid displacement of the workpiece during testing.

[0053] The hydraulic cylinder 14 drives the lower pressure plate 13 to slide downward along the mounting rod 12 and the guide rod 133. The lower pressure plate 13 simultaneously drives several taps 131 to move towards the threaded hole of the car sunroof guide rail body 23. The first compression spring 134 provides buffer when the tap 131 contacts the workpiece to avoid hard contact damage to the tap 131 or the threaded hole. When the tap 131 sinks to the specified position, the sensor 135 at its bottom triggers a signal. The device determines that the test is qualified and enters the next process. If the tap 131 is not in place, the sensor 135 will not give a signal and will trigger the machine alarm to prevent the untapping workpiece from flowing into the next process.

[0054] After the inspection is completed, the ejection assembly 2 is activated to replace manual removal. The displacement groove 211 and the guide block 223 of the displacement plate 22 form a limiting guide. When the second compression spring 243 is damaged due to long-term use or the elasticity of the second compression spring 243 fails, the screw 221 adjusts the displacement plate 22. At this time, the displacement plate 22 moves upward, which can simultaneously press against several second compression springs 243, thereby causing the ejection rod 244 to move upward synchronously, so that the top of the ejection rod 244 contacts the bottom of the car sunroof guide rail body 23, thereby performing the ejection operation of the car sunroof guide rail body 23.

[0055] When the second compression spring 243 needs to be replaced, the staff manually rotates the storage shell 242 counterclockwise. The storage shell 242 drives the rotating column 2421 to rotate synchronously. The rotating column 2421 rotates in the rotating groove 2411. When the rotating groove 2411 matches the position of the placement groove 2412, the storage shell 242 can be removed as a whole.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
