Description

Technical Field

[0001] This utility model relates to the field of lamp housing technology, specifically to a fixture for measuring the size of lamp housings. Background Technology

[0002] Headlights, also known as automotive headlights, provide illumination to the road ahead of a vehicle in low-light conditions, ensuring safe driving. During the manufacturing process, the headlight housing needs to be clamped to prevent instability during processing.

[0003] In the existing technology, the fixtures for measuring the size of lamp housings often use a manual clamping method. This means that the operator rotates the bolts, wrenches, or uses manual parts such as clips to push the clamping blocks to squeeze and fix the lamp housing, thereby positioning the lamp housing on the testing platform.

[0004] This manual clamping method relies entirely on the operator's physical strength and experience to control the clamping force. On the one hand, when the operator applies insufficient force, the clamping force cannot meet the testing requirements, and the lamp housing is prone to displacement due to external forces (such as sensor contact or slight equipment vibration) during the testing process, leading to deviations in the test data or even test failure. On the other hand, if the operator applies excessive force, exceeding the tolerance range of the lamp housing material, it will cause physical damage such as dents and cracks on the surface of the lamp housing. Especially for lamp housings made of brittle materials such as plastic and glass, the risk of damage is higher, and the versatility is poor.

[0005] In light of this, we have introduced a fixture for measuring the size of lamp housings. Utility Model Content

[0006] The purpose of this invention is to provide a fixture for detecting the size of lamp housings, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fixture for detecting the size of a lamp housing, comprising: a lower base plate, an upper top plate, and a positioning cylinder;

[0008] The bottom plate is provided with a top plate, and the top plate is provided with a placement platform.

[0009] The upper top plate is positioned above the lower bottom plate, and a fixing cylinder is provided at the bottom of the upper top plate, with a guide column inside the fixing cylinder;

[0010] The positioning cylinder is located on the top of the bottom plate and is aligned with the fixing cylinder. The guide post is inserted into the positioning cylinder.

[0011] The top of the placement platform is equipped with a clamping mechanism. Through the cooperation of the cylinder and the moving block of the clamping mechanism, the moving block clamps the lamp housing on the top of the placement platform.

[0012] Preferably, the clamping mechanism includes a base connected to the top of the placement platform, a positioning plate A connected to the side of the base, a positioning plate B connected to the side of the positioning plate A, a locking sleeve connected to the side of the positioning plate B, brackets connected to the top two sides of the placement platform, a cylinder connected to the top of the brackets, and a moving block connected to the output end of the cylinder.

[0013] Preferably, the top of the placement platform is connected to a nut electric locking component A, and a rigid displacement sensor A is connected to one side of the nut electric locking component A. The rigid displacement sensor A is connected to the side of the positioning plate B. The nut electric locking component A is used to lock and fix the relevant components to ensure the firmness of the connection. The rigid displacement sensor A is installed on the side of the positioning plate B and can accurately detect the size data of the corresponding side of the lamp housing, providing key data support for judging the qualification of the lamp housing size.

[0014] Preferably, a connecting frame is provided on the top of the placement platform on the side of the nut electric lock component A. An L-shaped block is connected to the side of the connecting frame, and the L-shaped block is connected to the placement platform. The connecting frame and the L-shaped block form a combined support structure. The connecting frame enhances the connection stability between the components, and the L-shaped block further strengthens the installation strength of the connecting frame through its connection with the placement platform. The two work together to improve the load-bearing capacity of the components in this area and the overall structural stability.

[0015] Preferably, a nut-electric locking component B is connected to the side of the top plate, and a rigid displacement sensor B is connected to the side of the nut-electric locking component B. The nut-electric locking component B fixes the installation position of the rigid displacement sensor B, preventing it from loosening or shifting during the detection process. The rigid displacement sensor B detects the side profile dimensions of the lamp housing from the side of the top plate, supplementing the shortcomings of top detection and realizing multi-directional dimension detection.

[0016] Preferably, a positioning plate C is connected to the top of the placement platform, a positioning plate D is connected to the surface of the positioning plate C, and a concave frame is connected to the other side of the positioning plate C.

[0017] Preferably, a fixture is connected to one side of the top of the placement platform, and a detection component is connected to the center of the top side of the placement platform. A cylindrical pin is connected to the surface of the detection component, and a sensor is connected to the surface of the detection component. The fixture is designed according to the specific shape of the lamp housing to provide a close fit support for the lamp housing. The detection component serves as the mounting carrier for the sensor and the cylindrical pin. The cylindrical pin is inserted into the corresponding hole in the lamp housing to achieve precise positioning, and the sensor detects the dimensional parameters of the lamp housing at that position in real time.

[0018] Preferably, a limiting block is connected to one side of the placement platform, and a clamping block is connected to the other side of the placement platform. The clamping block enhances the structural strength of the side of the placement platform and also plays an auxiliary role in clamping and positioning the other side of the lamp housing, thereby improving the overall clamping effect.

[0019] Preferably, a handle is connected to the side surface of the lower base plate, a reinforcing plate is connected to the side surface of the lower base plate located on the top plate, and a protective cover is connected to the top of the lower base plate. The handle facilitates the operator to move and transport the entire tooling. The reinforcing plate enhances the connection strength between the top plate and the lower base plate through its connection with the lower base plate and the top plate. The protective cover isolates the key components inside the tooling from the outside world, preventing dust, debris from entering or accidental collisions from damaging the components.

[0020] Preferably, the top of the placement platform is connected to a positioning plate E, and the positioning plate E and other components cooperate with each other to form a surrounding positioning of the lamp housing from different directions, further ensuring the positional accuracy of the lamp housing on the placement platform and providing a reliable positioning basis for subsequent accurate testing.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) The clamping mechanism uses a cylinder as a power source. The cylinder drives the moving block to clamp the lamp housing, which not only saves manpower, but also provides a stable clamping force. The clamping force can be controlled by adjusting the air pressure of the cylinder. It is suitable for lamp housings of different specifications and materials, avoiding the problem of lamp housing displacement due to insufficient clamping force or damage to the lamp housing due to excessive clamping force, and improving the stability and efficiency of clamping operation.

[0023] (2) Through the cooperation of the fixed cylinder, guide column and positioning cylinder, the precise positioning between the upper top plate and the lower bottom plate is achieved, ensuring the relative position accuracy of the upper and lower structures. The multiple positioning plates (positioning plate A, positioning plate B, positioning plate C, positioning plate D, positioning plate E) on the top of the placement platform, as well as the fixture, cylindrical pin and other components, position the lamp housing in multiple directions and angles, ensuring that the lamp housing is always in the correct detection position during the detection process, which greatly improves the accuracy of the detection.

[0024] (3) By integrating multiple detection components such as rigid displacement sensor A, rigid displacement sensor B, and sensors, it is possible to detect multiple key dimensions of the lamp housing in real time. The sensor is installed in a precise position and works well with the positioning components. It can directly obtain the size data of the lamp housing, reducing the error and tedious steps of manual measurement. At the same time, the layout of each detection component is reasonable and does not affect the placement and clamping operation of the lamp housing, making the detection process more convenient and efficient, and can fully reflect the size accuracy of the lamp housing.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] 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.

[0032] Please see Figure 1-4 This utility model provides a technical solution: a fixture for detecting the size of a lamp housing, comprising: a lower base plate 1, a top plate 6 on the top of the lower base plate 1, and a placement platform 7 on the top of the top plate 6;

[0033] The upper top plate 2 is positioned above the lower bottom plate 1. The bottom of the upper top plate 2 is provided with a fixing cylinder 3, and the inside of the fixing cylinder 3 is provided with a guide column 4. The upper top plate 2 achieves precise docking with the lower bottom plate 1 through the combination of the fixing cylinder 3 and the guide column 4. The fixing cylinder 3 provides installation space and limit function for the guide column 4. The guide column 4 can flexibly extend and retract within the fixing cylinder 3 to provide guidance for the up and down movement of the upper top plate 2.

[0034] The positioning cylinder 5 is set on the top of the lower base plate 1 and is aligned with the fixed cylinder 3. The guide post 4 is inserted into the positioning cylinder 5. The precise alignment of the positioning cylinder 5 and the fixed cylinder 3 ensures the coaxiality of the guide post 4 when it is inserted. After the guide post 4 is inserted into the positioning cylinder 5, a vertical guide positioning structure is formed between the upper top plate 2 and the lower base plate 1, which effectively prevents the tooling from shifting or shaking during operation.

[0035] The top of the placement platform 7 is provided with a clamping mechanism. Through the cooperation of the cylinder 26 and the moving block 28 of the clamping mechanism, the moving block 28 clamps the lamp housing on the top of the placement platform 7.

[0036] The clamping mechanism includes a base 22 connected to the top of the placement platform 7, a positioning plate A29 connected to the side of the base 22, a positioning plate B10 connected to the side of the positioning plate A29, and a locking sleeve 14 connected to the side of the positioning plate B10. Supports 27 are connected to both sides of the top of the placement platform 7. A cylinder 26 is connected to the top of the support 27, and a moving block 28 is connected to the output end of the cylinder 26. The base 22 provides an installation foundation for the clamping mechanism. The positioning plates A29 and B10 cooperate to form a lateral positioning reference. The locking sleeve 14 enhances the connection strength of the positioning plate B10. The support 27 provides stable support for the cylinder 26, ensuring that the output force of the cylinder 26 is stably transmitted to the moving block 28, thus achieving reliable clamping of the lamp housing.

[0037] The top of the placement platform 7 is connected to a nut electric locking component A16. A rigid displacement sensor A13 is connected to one side of the nut electric locking component A16, and the rigid displacement sensor A13 is connected to the side of the positioning plate B10. The nut electric locking component A16 is used to lock and fix the relevant components to ensure the firmness of the connection. The rigid displacement sensor A13 is installed on the side of the positioning plate B10 and can accurately detect the size data of the corresponding side of the lamp housing, providing key data support for judging the qualification of the lamp housing size.

[0038] A connecting frame 15 is provided on the top of the placement platform 7, located on the side of the nut electric lock component A16. An L-shaped block 18 is connected to the side of the connecting frame 15, and the L-shaped block 18 is connected to the placement platform 7. The connecting frame 15 and the L-shaped block 18 form a combined support structure. The connecting frame 15 enhances the connection stability between the components, and the L-shaped block 18 further strengthens the installation strength of the connecting frame 15 through its connection with the placement platform 7. The two work together to improve the load-bearing capacity of the components in this area and the overall structural stability.

[0039] The top plate 6 is connected to a nut electric locking component B12 on its side, and a rigid displacement sensor B9 is connected to the side of the nut electric locking component B12. The nut electric locking component B12 fixes the installation position of the rigid displacement sensor B9 to prevent it from loosening or shifting during the detection process. The rigid displacement sensor B9 detects the side profile dimensions of the lamp housing from the side of the top plate 6, which supplements the lack of top detection and realizes multi-directional dimension detection.

[0040] The top of the placement platform 7 is connected to a positioning plate C23, and the surface of the positioning plate C23 is connected to a positioning plate D24. The other side of the positioning plate C23 is connected to a concave frame 25. The positioning plate C23 serves as a basic positioning component and is perpendicularly connected to the positioning plate D24 to form a right-angle positioning reference, which can accurately position the corner of the lamp housing. The concave frame 25 provides auxiliary positioning for the lamp housing from the other side. Together, the three components constitute a complete lateral positioning system to ensure the accuracy of the lamp housing placement position.

[0041] A fixture 31 is connected to one side of the top of the placement platform 7. A detection element 34 is connected to the center of the top side of the placement platform 7. A cylindrical pin 33 is connected to the surface of the detection element 34. A sensor 32 is connected to the surface of the detection element 34. The fixture 31 is designed according to the specific shape of the lamp housing to provide a close fit support for the lamp housing. The detection element 34 serves as the mounting carrier for the sensor 32 and the cylindrical pin 33. The cylindrical pin 33 is inserted into the corresponding hole of the lamp housing to achieve precise positioning. The sensor 32 then detects the dimensional parameters of the lamp housing at that position in real time.

[0042] The side of the placement platform 7 is connected to a limiting block 19, and the other side of the placement platform 7 is connected to a clamping block 30. The clamping block 30 enhances the structural strength of the side of the placement platform 7, and at the same time plays an auxiliary role in clamping and positioning the other side of the lamp housing, thereby improving the overall clamping effect.

[0043] A handle 20 is connected to the side surface of the lower base plate 1. A reinforcing plate 8 is connected to the side surface of the upper top plate 6. A protective cover 11 is connected to the top of the lower base plate 1. The handle 20 facilitates the operator to move and transport the entire tooling. The reinforcing plate 8 enhances the connection strength between the upper top plate 6 and the lower base plate 1 by connecting with the lower base plate 1 and the upper top plate 6. The protective cover 11 isolates the key components inside the tooling from the outside world, preventing dust, debris from entering or accidental collisions from damaging the components.

[0044] The top of the placement platform 7 is connected to a positioning plate E17. The positioning plate E17 and other components cooperate with each other to form a surrounding positioning of the lamp housing from different directions, further ensuring the positional accuracy of the lamp housing on the placement platform 7 and providing a reliable positioning basis for subsequent accurate testing.

[0045] Specifically, in use, the lower base plate 1 serves as the basic support component of the entire fixture, providing a stable installation platform for the upper structure. The top plate 6 installed on top of it plays a connecting role, and the placement platform 7 on the top of the top plate 6 is the direct placement area for the lamp housing, used to support the lamp housing to be tested. The upper top plate 2 is set above the lower base plate 1, forming a corresponding structure. The guide column 4 is installed inside the fixing cylinder 3 at the bottom of the upper top plate 2. The positioning cylinder 5 at the top of the lower base plate 1 is precisely aligned with the fixing cylinder 3. The guide column 4 is inserted into the positioning cylinder 5. Through this guiding cooperation, the relative position positioning between the upper top plate 2 and the lower base plate 1 is achieved, ensuring the verticality and stability of the upper and lower structures, and providing a basic structural guarantee for subsequent testing operations.

[0046] The operator places the lamp housing to be tested on the top of the placement platform 7. During the placement process, the positioning components such as positioning plate A29, positioning plate B10, positioning plate C23, positioning plate D24, and positioning plate E17 on the top of the placement platform 7 will initially limit and guide the lamp housing. These positioning plates are designed according to the shape and structure of the lamp housing, which can enable the lamp housing to be quickly placed in the preset testing position and avoid the lamp housing being placed crookedly, thus affecting the testing accuracy. At the same time, the fixture 31 can also assist the lamp housing in performing preliminary shape matching and positioning.

[0047] After the lamp housing is initially placed, the clamping mechanism starts to work. The cylinder 26 in the clamping mechanism is installed on the brackets 27 on both sides of the top of the placement platform 7. The cylinder 26 serves as a power source, and its output end is connected to the moving block 28. When the cylinder 26 is started, the piston rod of the cylinder 26 extends, driving the moving block 28 to move towards the lamp housing. During the movement, the base 22 provides stable support for components such as the positioning plate A29. The positioning plate A29 and the positioning plate B10 play a certain guiding role in the movement direction of the moving block 28. As the moving block 28 continues to move, it eventually contacts the surface of the lamp housing and gradually applies pressure, clamping the lamp housing on the top of the placement platform 7. At the same time, the locking sleeve 14 on the side of the positioning plate B10 can further enhance the stability of the positioning and ensure that the lamp housing will not be displaced during the testing process.

[0048] After the lamp housing is clamped and fixed, the various detection-related components begin to work. The nut electric lock A16 on the top of the placement platform 7 and the nut electric lock B12 on the side of the top plate 6 can lock and fix the relevant positioning components to prevent the positioning accuracy from decreasing due to loosening of the components during the detection process. The rigid displacement sensor A13 is connected to the side of the positioning plate B10 and connected to one side of the nut electric lock A16. The rigid displacement sensor B9 is connected to the side of the nut electric lock B12. The rigid displacement sensor A13, rigid displacement sensor B9 and sensor 32 can detect the size data of key parts of the lamp housing in real time. The detection component 34, located in the center of the top side of the placement platform 7, is equipped with a cylindrical pin 33 and a sensor 32. The cylindrical pin 33 can be inserted into a specific hole in the lamp housing for precise positioning, and the sensor 32 detects the corresponding position size of the lamp housing. The connecting bracket 15 and the L-shaped block 18 play an auxiliary fixing role for the nut electric lock A16 and other components, enhancing the stability of the detection components.

[0049] After the test is completed, the piston rod of cylinder 26 retracts, moving the moving block 28 away from the lamp housing, releasing the clamping state on the lamp housing. The operator can then remove the tested lamp housing from the placement table 7. Subsequently, all components return to their initial state, awaiting the next test operation. During this process, the limit block 19 prevents the moving block 28 from moving excessively, protecting the equipment and the lamp housing. The clamping block 30 also plays an auxiliary limiting role in the overall structure. The handle 20 on the surface of the lower base plate 1 facilitates the operator to move and transport the entire fixture. The reinforcing plate 8 enhances the connection strength between the lower base plate 1 and the top plate 6. The protective cover 11 provides dustproof and collision-proof protection for the internal precision components.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
