Description

Technical Field

[0001] This utility model relates to the field of automotive testing tooling technology, specifically to an integrated door ring flipping testing tooling for new energy vehicles. Background Technology

[0002] In the field of new energy vehicle manufacturing, the integrated door ring is a key load-bearing component of the vehicle body frame. Its structural precision directly determines the sealing performance of the door assembly, the vehicle body's impact resistance, and the overall driving safety. Therefore, during the production process, it is necessary to strictly test its dimensional tolerances, appearance defects, and the integrity of welding points.

[0003] Currently, traditional testing methods mostly rely on manual handheld testing tools for single-point measurements. However, due to the large size and weight of integrated door rings, their placement angle and position need to be frequently adjusted during the testing process to achieve testing of different surfaces. Existing testing equipment lacks convenient flipping and positioning mechanisms, usually requiring multiple operators to coordinate adjustments. This not only makes the operation difficult but also easily leads to scratches or structural deformation of the door ring surface due to uneven force during the adjustment process, further affecting the testing accuracy and product qualification rate. Therefore, this utility model proposes an integrated door ring flipping testing fixture for new energy vehicles to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an integrated door ring flipping detection fixture for new energy vehicles, so as to solve the problem of inefficient door ring detection mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated door ring flipping detection fixture for new energy vehicles, comprising a detection base, on which two sets of guide frames are fixedly installed, the two sets of guide frames being symmetrically arranged on the detection base, a screw being vertically rotatably connected in the guide frame, the screw being drivenly connected to a fixed seat, a transition post being rotatably connected to one side of the fixed seat, a driven tooth being fixedly sleeved on the outer wall of the transition post, a drive rod being installed on one side of one set of driven teeth, the drive rod having a vertical tooth groove, the driven tooth meshing with the tooth groove, and a clamping frame being fixedly connected to one end of the transition post.

[0006] Preferably, a control motor is mounted at the bottom of the guide frame, and the output end of the control motor is connected to the screw drive.

[0007] Preferably, the clamping frame is specifically constructed as a U-shaped structure, which encloses itself to form a clamping cavity. A positioning plate is adapted to be installed inside the clamping cavity. An adjusting column is threadedly connected to the top of the positioning plate. The other end of the adjusting column passes through and extends out of the top of the clamping frame along the top axis direction.

[0008] Preferably, an annular groove is provided on the side wall of the fixing seat, one end of the adapter post is adapted to be embedded in the annular groove, and the adapter post and the annular groove form a connection structure that can rotate relative to each other.

[0009] Preferably, the guide frame has guide grooves on both side walls, and the fixed seat has guide blocks extending from both ends. The fixed seat is slidably installed in the guide grooves in cooperation with the guide blocks at both ends.

[0010] Preferably, a fixing plate is welded to the top of the drive rod, and the fixing plate has positioning holes. The fixing plate is fixed to the top of one of the guide frames with bolts.

[0011] Preferably, an assembly frame is installed on the side wall of one of the guide frames, and a detection probe is installed on the assembly frame. The detection probe is electrically connected to the display screen, and the display screen is mounted on one of the guide frames.

[0012] Preferably, a controller is installed on the guide frame, and the controller is electrically connected to the control motors at the bottom of the guide frames on both sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The vertical height of the clamping frame can be adjusted through the transmission between the screw and the fixed seat. At the same time, the meshing structure of the driven tooth and the drive rod tooth groove can drive the adapter column and the clamping frame to rotate stably without the need for manual adjustment of the door ring position and angle. This effectively solves the problems of "high operation difficulty and reliance on manual labor" in traditional testing. In addition, the U-shaped clamping frame, together with the adjustment column and positioning plate, can quickly adapt to one-piece door rings of different sizes, making it more versatile. The controller can also achieve automatic adjustment by controlling the control motor, which greatly shortens the test preparation time and operation cycle and significantly improves the overall test efficiency.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: an integrated door ring flipping detection fixture for new energy vehicles, including a detection base 1, on which two sets of guide frames 2 are fixedly installed, the two sets of guide frames 2 are symmetrically arranged on the detection base 1, a screw 3 is vertically rotatably connected in the guide frame 2, a fixed seat 5 is driven by the screw 3, a transition post 6 is rotatably connected to one side of the fixed seat 5, a driven tooth 61 is fixedly sleeved on the outer wall of the transition post 6, a drive rod 10 is installed on one side of one set of driven teeth 61, the drive rod 10 has a vertical tooth groove, the driven tooth 61 meshes with the tooth groove, a clamping frame 7 is fixedly connected to one end of the transition post 6, a control motor 4 is assembled at the bottom of the guide frame 2, and the output end of the control motor 4 is driven by the screw 3.

[0020] By controlling the motor 4 to drive the screw 3 to rotate, the fixed base 5 is driven to rise and fall vertically along the guide frame 2, eliminating the need for manual handling to adjust the height of the door ring. At the same time, by utilizing the meshing structure between the driven teeth 61 on the outer wall of the adapter column 6 and the tooth groove of the drive rod 10, the adapter column 6 can be driven to rotate the clamping frame 7, realizing the automatic switching of different detection surfaces of the door ring. This completely eliminates the dependence on manual coordination and adjustment, greatly reduces the difficulty of operation, avoids the physical exertion and coordination errors during manual operation, and all adjustment actions are based on the stable support of the detection base 1, further ensuring operational safety.

[0021] Please see Figure 2 as well as Figure 3 It is understood that the clamping frame 7 has a U-shaped structure, which encloses itself to form a clamping cavity. A positioning plate 8 is fitted inside the clamping cavity. An adjusting column 9 is threadedly connected to the top of the positioning plate 8. The other end of the adjusting column 9 passes through and extends out of the top of the clamping frame 7 along the top axis direction.

[0022] The clamping frame 7 adopts a U-shaped structure, and the clamping cavity formed by its enclosure can provide an open clamping space to accommodate one-piece door rings of different widths. At the same time, by rotating the adjusting column 9 that passes through the top of the clamping frame 7, the positioning plate 8 that is threaded to it can be driven to move up and down in the clamping cavity. When the adjusting column 9 is rotated upward, the positioning plate 8 moves upward, which can increase the height of the clamping cavity to accommodate thicker door rings.

[0023] Please see Figure 3 It is understood that an annular groove 51 is provided on the side wall of the fixed base 5, and one end of the adapter post 6 is adapted to be embedded in the annular groove 51, and the adapter post 6 and the annular groove 51 form a connection structure that can rotate relative to each other.

[0024] When the adapter pin 6 drives the clamping frame 7 and the door ring to rotate under the meshing drive of the driven tooth 61 and the drive rod 10, the annular groove 51 can ensure that the adapter pin 6 always rotates stably around the fixed axis, avoiding the door ring from shifting position due to unstable rotation, providing a stable positioning basis for the subsequent measurement of the detection probe 12, and indirectly improving the accuracy of the detection data.

[0025] Please see Figure 1 , Figure 3 , Figure 4 Understandably, the guide frame 2 has guide grooves 21 on both sides, and the fixed seat 5 has guide blocks 52 extending from both ends. The fixed seat 5 is slidably installed in the guide grooves 21 in cooperation with the guide blocks 52 at both ends.

[0026] When the control motor 4 drives the screw 3 to raise and lower the fixed seat 5 vertically, the guide block 52 moves along the trajectory of the guide groove 21, which can effectively limit the offset of the fixed seat 5 and prevent the fixed seat 5 from swaying or tilting due to the transmission gap of the screw 3.

[0027] Please see Figure 2 , Figure 4 It is understood that a fixing plate 101 is welded to the top of the drive rod 10. The fixing plate 101 has positioning holes. The fixing plate 101 is fixed to the top of one of the guide frames 2 with bolts. The installation of the fixing plate 101 and the bolts facilitates the subsequent disassembly and maintenance of the drive rod 10.

[0028] Please see Figure 1 , Figure 3 , Figure 4 It is understood that an assembly frame 11 is installed on the side wall of one of the guide frames 2, and a detection probe 12 (Omron ZP-L series sensor) is installed on the assembly frame 11. The detection probe 12 is located directly above the clamping frame 7, and the detection probe 12 is electrically connected to the display screen 13. The display screen 13 is mounted on one of the guide frames 2.

[0029] Please see Figure 2It is understood that a controller 14 is installed on the guide frame 2. The controller 14 (Siemens series) is electrically connected to the control motor 4 at the bottom of the guide frame 2 on both sides, which can realize the synchronous control of the control motor 4 on both sides.

[0030] When in use, first place the integrated door ring into the U-shaped clamping cavity of the clamping frame 7, rotate the adjusting column 9 to drive the positioning plate 8 to move down in the clamping cavity until it fits tightly against the top of the door ring, thus achieving a stable clamping of the door ring. Next, the controller 14 (Siemens series) on the guide frame 2 is started. The controller 14 synchronously drives the control motor 4 at the bottom of the guide frame 2 on both sides. The output end of the control motor 4 drives the screw 3 to rotate. The fixed seat 5 connected to the screw 3 is raised and lowered along the guide frame 2. At this time, the guide blocks 52 at both ends of the fixed seat 5 slide along the guide groove 21 on the side wall of the guide frame 2, limiting the offset of the fixed seat 5 and ensuring that the door ring is raised and lowered smoothly to the appropriate position below the detection probe 12 (Omron ZP-L series sensor). If different sides of the door ring need to be inspected, the controller 14 coordinates the transmission structure to make the driven teeth 61 on the outer wall of the adapter column 6 mesh with the tooth groove of the drive rod 10 and rotate (the drive rod 10 is fixed to the top of the guide frame 2 by the fixing plate 101 and bolts). One end of the adapter column 6 is embedded in the annular groove 51 of the fixing seat 5 and rotates stably around the fixed axis, driving the clamping frame 7 and the door ring to switch angles. Then, with the detection probe 12 located directly above the clamping frame 7, it collects data such as the door ring size and welding points in real time and transmits the data to the display screen 13 on the guide frame 2 to realize the visualization of the detection results and complete the automated detection of the door ring.

[0031] 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.
