Description

Technical Field

[0001] This utility model belongs to the field of vehicle lamp size inspection technology, specifically relating to an inspection tooling for vehicle lamp grinding and drilling. Background Technology

[0002] In the automotive manufacturing industry, headlights are a critical component for ensuring driving safety. Their dimensional accuracy directly affects assembly quality, lighting performance, and aesthetic consistency. Especially for headlights before drilling, it is essential to ensure that key dimensional parameters such as drilling position, hole diameter, and edge flatness strictly conform to design standards. Otherwise, excessive assembly gaps, reduced sealing performance, and even safety hazards such as deviations in lighting angles may occur. Therefore, it is necessary to inspect the dimensions of headlights before drilling.

[0003] Existing methods for inspecting the size of vehicle lights mainly rely on manual measurement using tools such as calipers and micrometers, or random inspection using fixed fixtures and gauges. However, manual measurement is not only inefficient and difficult to adapt to the cycle time requirements of automated production lines, but the measurement results are also easily affected by subjective factors such as the operator's experience and physical condition, resulting in large fluctuations in accuracy and poor data consistency. Furthermore, manual inspection is slow, which greatly reduces the efficiency of inspection. Utility Model Content

[0004] The purpose of this invention is to provide a testing fixture for grinding and drilling automotive lights, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a testing fixture for grinding and drilling automotive lights, comprising:

[0006] A measuring base plate, wherein a vertical plate is connected to the top of the measuring base plate and two sets of partitions are connected to the middle of the vertical plate;

[0007] The first pillar has several sets of pillars, all of which are connected to two sets of partitions. Several second pillars are connected to the uprights. The second pillars are equipped with stroke sensors for detecting the size of the headlights.

[0008] A heavy-duty connector is mounted on the measuring base plate and is used to realize the electrical connection between the measuring base plate and external equipment.

[0009] Preferably, the first support column is provided with a plurality of positioning grooves for fixing the vehicle lights and the positioning grooves are provided with pin holes.

[0010] Preferably, a reinforcing beam connects the two sets of partitions, and side plates are connected to both ends of the upright plate, with a surrounding plate fixedly connected between the side plates.

[0011] Preferably, the measuring base plate has two sets of handles connected to both ends of its top.

[0012] Preferably, both the measuring base plate and the side plate are connected to supports, and the supports are connected to guide columns.

[0013] Preferably, the measuring base plate is equipped with a pneumatic multi-connector.

[0014] Preferably, the heavy-duty connector is provided with a protective shell on top.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) As the core detection element, the stroke sensor can convert the size parameters of the car lamp into electrical signals for quantitative detection, avoiding errors caused by subjective judgment during manual measurement. The stroke sensor contacts the car lamp through its contact head and transmits the data detected by the stroke sensor to the production line control system in real time, which greatly improves the detection efficiency. Moreover, this detection fixture can be integrated into the car lamp grinding and drilling production line. The stroke sensor can respond and feed back data in real time, which significantly improves the overall detection efficiency. In addition, the two sets of detection fixtures on the measuring base plate can detect two sets of car lamps at the same time, which greatly improves the detection efficiency.

[0017] (2) By placing the vehicle light to be tested on the first pillar, the vehicle light is initially limited by the positioning groove, and then the positioning pin is inserted through the pin hole to ensure that the position of the vehicle light is fixed during the testing process, avoiding the testing deviation caused by displacement, so that the positioning groove and pin hole on the first pillar of the device can achieve rapid positioning of the vehicle light.

[0018] (3) The reinforced crossbeams enhance the load-bearing capacity of the partitions, while the side panels and enclosures form a protective structure, reducing interference from the external environment on the detection. The handles facilitate the handling and maintenance of the tooling, and the supports and guide columns ensure the stability of the tooling during the detection process, reducing the impact of vibration on the sensor's detection accuracy. These structural designs extend the service life of the tooling while improving the ease of operation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] This utility model provides, for example Figure 1-5 The inspection fixture shown includes:

[0028] Measuring base plate 1, the top of the measuring base plate 1 is connected to a vertical plate 2 and the middle of the vertical plate 2 is connected to two sets of partitions 3. The vertical plate 2 is provided with a slot 20, which can be used to reduce the overall weight of the tooling.

[0029] The first support column 4 has several sets, all of which are connected to two sets of partition plates 3. Several second support columns 5 are connected to the upright plate 2. Several fixing holes 19 are provided on the upright plate 2 and the partition plate 3. The first support column 4 and the second support column 5 can be screwed together by bolts passing through the fixing holes 19, which makes disassembly and installation convenient, thus facilitating subsequent parts replacement and maintenance. The second support column 5 is equipped with a stroke sensor 6 for detecting the size of the headlight. The stroke sensor 6 is a Keyence GT2-A12, which is a high-precision contact digital stroke sensor.

[0030] The heavy-duty connector 7 is mounted on the measuring base plate 1 and is used to realize the electrical connection between the measuring base plate 1 and external equipment. The bottom of the heavy-duty connector 7 is connected to several mounting feet 25. The heavy-duty connector 7 is screwed to the measuring base plate 1 by bolts passing through the mounting feet 25.

[0031] The first support column 4 is provided with several positioning grooves 8 for fixing the vehicle lights, and the positioning grooves 8 are provided with pin holes 17.

[0032] A reinforcing beam 9 is connected between the two sets of partitions 3, and side plates 10 are connected to both ends of the upright plate 2, with a surrounding plate 11 fixedly connected between the side plates 10.

[0033] Two sets of handles 12 are connected to the top ends of the measuring base plate 1. The two sets of handles 12 are installed at the top ends of the base plate respectively, forming symmetrical force points. The operator can hold the handles 12 with both hands and lift or move the tooling smoothly by applying force evenly.

[0034] Both the measuring base plate 1 and the side plate 10 are connected to a support 13, and a guide post 14 is connected inside the support 13. During tooling installation or maintenance, the guide post 14 can be used as a positioning reference to help quickly calibrate the relative position of the measuring base plate 1 and the side plate 10 and reduce assembly errors.

[0035] The measuring base plate 1 is equipped with a pneumatic multi-connector 15. The pneumatic multi-connector 15 is installed here to centrally connect the various pneumatic pipelines required by the tooling, avoiding the mess caused by the dispersed arrangement of pipelines.

[0036] The heavy-duty connector 7 is equipped with a protective shell 16 on its top. During daily use, operators may come into contact with the equipment, or tools or parts may be accidentally dropped. The protective shell 16 can prevent the heavy-duty connector 7 from being directly damaged by impact. The protective shell 16 and the heavy-duty connector 7 are locked together by a locking frame 23. The locking frame 23 can be tightened or loosened by turning the bolts used to fix the locking frame 23, so that the protective shell 16 can be opened for maintenance of the heavy-duty connector 7. The protective shell 16 is also provided with a wiring hole 22, which allows wires to pass through the wiring hole 22 and connect to the heavy-duty connector 7 inside the protective shell 16 for wiring operations.

[0037] The inspection fixture for this headlight grinding and drilling process involves the operator placing the headlight on the bearing surface of the first support pillar 4. At this point, the edge of the headlight will be embedded in the pre-set positioning groove 8 of the first support pillar 4. The shape of the positioning groove 8 matches the contour of the headlight edge, limiting the horizontal and vertical displacement of the headlight. Then, a positioning pin is inserted through the pin hole 17. The positioning pin passes through the pre-drilled positioning hole on the headlight, further fixing the headlight vertically. This ensures that the headlight will not shift position due to slight vibration or external force during the inspection process. After positioning is complete, the travel sensor 6 is mounted on the second support pillar 5 via a fixed bracket. Its height and horizontal position can be pre-adjusted according to the position of the headlight grinding and drilling area. The contact head 18 of the travel sensor 6 will naturally fit or correspond to the key dimensions after the headlight grinding and drilling—if detecting the drill hole diameter, the contact head 18 will extend into the hole and contact the hole wall; if detecting the plane height, the contact head 18 will directly fit against the plane. When the head unit 18 senses the dimensional state of the headlight grinding area (such as changes in hole diameter or differences in surface height), it will generate a slight mechanical displacement as the size changes. The sensing element inside the stroke sensor 6 will capture this displacement and convert the mechanical displacement into a corresponding electrical signal. The electrical signal generated by the stroke sensor 6 will be transmitted to the heavy-duty connector 7 through the line. The heavy-duty connector 7, as a signal relay component, can stably receive the electrical signal from the sensor while avoiding the influence of external electromagnetic interference on the signal. Then, the heavy-duty connector 7 will transmit the processed signal to the external control system (such as the control host of the production line). The control system will call the pre-stored standard parameters of the headlight grinding size for this model and compare the dimensional state corresponding to the received electrical signal with the standard parameters. If the dimensional state corresponding to the electrical signal meets the standard parameter range, the system will determine that the headlight is qualified; if it exceeds the standard parameter range, it will be determined as unqualified, thus quickly completing the headlight size inspection.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
