Description

Technical Field

[0001] This utility model relates to the technical field of new energy vehicle manufacturing and processing equipment, specifically a new energy vehicle integrated door ring clamp. Background Technology

[0002] As new energy vehicles develop towards lightweight and high-strength, the integrated door ring, as a key load-bearing structural component of the vehicle body, directly affects the vehicle body assembly accuracy and collision safety. Therefore, it places extremely high demands on the positioning and clamping stability of the fixtures during the processing.

[0003] In existing integrated door ring processing technology, the clamping of the door ring mostly adopts traditional multi-drive fixtures or single-point clamping structures. Among them, multi-drive fixtures require multiple independent cylinders to control the movement of the upper, left, and right clamping blocks respectively. Due to the differences in air pressure fluctuations and response speeds of each cylinder, the clamping blocks are prone to asynchronous movement. For example, when the left clamping block has completed clamping, the right clamping block is still in a moving state, causing the door ring to be unbalanced in force during clamping, resulting in displacement or slight deformation. Subsequent processing requires additional precision calibration, which not only reduces production efficiency but may also affect the structural integrity of the door ring due to repeated adjustments. Therefore, this utility model proposes an integrated door ring fixture for new energy vehicles to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated door ring clamp for new energy vehicles to solve the clamping offset problem mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated door ring clamp for new energy vehicles, including a clamping frame, on which a model limiting frame is fixedly mounted, and clamping blocks are arranged on all four sides of the model limiting frame; One end of each clamping block is fixedly connected to a guide post, and a driven block is installed on the guide post connected to the left and right clamping blocks. A rectangular plate is fixedly connected to the end of the guide post connected to the upper clamping block. The two sides of the rectangular plate extend downward to form fixing rods. An active block is integrally formed at the lower end of the fixing rods. The contact surfaces between the driven block and the driving block are adapted inclined surface structures; The upper part of the rectangular plate is connected to the output end of the cylinder, and the cylinder is fixedly installed at the top of the clamping frame.

[0006] Preferably, the clamping block located below has a threaded guide post on the outer wall of one end, and the guide post is screwed onto the model limiting frame through the threaded engagement.

[0007] Preferably, springs are fitted on the guide pillars located at the top and on the left and right sides, and the other end of each spring is connected to the model limiting frame.

[0008] Preferably, the upper surface of the rectangular plate is equipped with an adapter frame, the adapter frame adopts a U-shaped structure design, the two ends of the adapter frame are symmetrically distributed and fixedly connected to the upper surface of the rectangular plate respectively, and the output end of the cylinder is fixedly connected to the middle area of ​​the adapter frame.

[0009] Preferably, two extension columns are symmetrically spirally connected on the rectangular plate, and the two extension columns penetrate the top of the clamping frame.

[0010] Preferably, the fixing rod has a weight-reducing groove.

[0011] Preferably, the clamping block has a V-shaped structure design, and its clamping end face is fitted with a rubber partition using Velcro.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By employing a structure consisting of a cylinder, adapter frame, rectangular plate, driving block, and driven block, multi-directional clamping can be completed with the drive of a single cylinder. When the cylinder output drives the rectangular plate downward through the U-shaped adapter frame, the driving blocks on the fixed rods on both sides of the rectangular plate, with the help of inclined surfaces, synchronously push the driven blocks on the left and right guide pillars, causing the left and right clamping blocks to move towards the center in the horizontal direction. At the same time, the upper clamping block presses down synchronously with the guide pillar, forming a three-way coordinated clamping in the upper, left, and right directions. This design solves the problem of asynchronous clamping caused by the response differences of multiple cylinders in traditional multi-drive fixtures, avoids the gate ring from shifting or deforming due to force imbalance, significantly improves machining positioning accuracy, reduces subsequent calibration processes, and increases production efficiency.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: an integrated door ring clamp for new energy vehicles, including a clamping frame 1, a model limiting frame 2 fixedly mounted on the clamping frame 1, clamping blocks 3 arranged on all four sides of the model limiting frame 2, and a guide post 31 fixedly connected to one end of each clamping block 3. A driven block 32 is installed on the guide post 31 connected to the left and right clamping blocks 3. A rectangular plate 5 is fixedly connected to the end of the guide post 31 connected to the upper clamping block 3. The two sides of the rectangular plate 5 extend downward to form a fixing rod 4. An active block 41 is integrally formed at the lower end of the fixing rod 4. The contact surface between the driven block 32 and the active block 41 is a matching inclined structure. The upper part of the rectangular plate 5 is connected to the output end of a cylinder 7. The cylinder 7 is fixedly installed at the top of the clamping frame 1.

[0019] Through the linkage structure of cylinder 7, rectangular plate 5, driving block 41, and driven block 32, multi-directional clamping can be driven by a single cylinder 7. In use, when the output end of cylinder 7 drives the rectangular plate 5 to move down, the driving block 41 of the fixed rod 4 on both sides of the rectangular plate 5, with the help of the inclined surface of the driven block 32, synchronously pushes the left and right guide posts 31 to drive the left and right clamping blocks 3 to move towards the center. At the same time, the upper clamping block 3 moves down synchronously with its own guide post 31, realizing three-way coordinated clamping in the upper, left, and right directions. The whole process does not have the problem of poor response of multiple cylinders 7, completely avoiding the force imbalance caused by asynchronous clamping of the door ring, solving the hidden danger of offset deformation of traditional fixtures from the root, and ensuring the machining positioning accuracy.

[0020] Please see Figure 4 Understandably, the clamping block 3 located below has a threaded guide post 31 at one end, which is screwed onto the model limiting frame 2 via the threaded connection.

[0021] Please see Figure 4 It is understood that springs 33 are fitted on the guide pillars 31 located at the top and on the left and right sides, and the other end of each spring 33 is connected to the model limiting frame 2.

[0022] When the cylinder 7 drives the rectangular plate 5 to move upward and release the workpiece, the compressed spring 33 releases its elastic potential energy, which drives the guide posts 31 on the top and left and right sides and the clamping block 3 to quickly return to the initial position. This design eliminates the need for additional driving or manual intervention, thus improving overall production efficiency.

[0023] Please see Figure 1 , Figure 3 It is understood that the upper surface of the rectangular plate 5 is equipped with an adapter frame 6. The adapter frame 6 adopts a U-shaped structure design. The two ends of the adapter frame 6 are symmetrically distributed and fixedly connected to the upper surface of the rectangular plate 5 respectively. The output end of the cylinder 7 is fixedly connected to the middle area of ​​the adapter frame 6.

[0024] The U-shaped adapter 6 is fixed to the rectangular plate 5 through two symmetrically distributed ends, and the output end of the cylinder 7 is connected to the middle area of ​​the adapter 6, forming a power transmission structure with the force in the middle and symmetrical transmission at both ends. The downward pressure output by the cylinder 7 is distributed to both ends through the middle area of ​​the adapter 6 and then synchronously transmitted to the rectangular plate 5, avoiding the rectangular plate 5 from tilting due to the offset of power transmission.

[0025] Please see Figure 2 It is understood that two extension columns 8 are symmetrically spirally connected on the rectangular plate 5, and the two extension columns 8 penetrate the top of the clamping frame 1.

[0026] Two extension columns 8 are symmetrically spirally connected to the rectangular plate 5 and pass through the top of the clamping frame 1. This design can effectively constrain the tilt and offset of the rectangular plate 5 during the lifting process, and avoid the swaying of the rectangular plate 5 caused by uneven force on the U-shaped adapter frame 6 or slight shaking at the output end of the cylinder 7.

[0027] Please see Figure 1 , Figure 2 It is understood that the fixed rod 4 has a weight reduction groove 411. By opening the weight reduction groove 411, the overall weight is reduced, which can reduce the motion inertia and make the lifting and lowering action of the cylinder 7 driving the rectangular plate 5, the fixed rod 4 and the active block 41 more agile. This shortens the response time of the clamping block 3 from the initial position to the clamping ring. At the same time, the weight reduction can reduce the load pressure at the output end of the cylinder 7, reduce the impact of air pressure fluctuations on clamping accuracy, and indirectly extend the service life of the cylinder 7.

[0028] Please see Figure 1 It is understood that the clamping block 3 has a V-shaped structure design, and its clamping end face is fitted with a rubber partition by Velcro.

[0029] The V-shaped clamping block 3 has two inclined surfaces that can form a two-point contact constraint with the arc edge of the door ring. Compared with flat clamping, it can significantly increase the clamping contact area. The design of the rubber partition can buffer the impact force at the moment of clamping, avoid scratches and indentations on the door ring surface caused by direct contact of the rigid clamping block 3, and protect the surface smoothness.

[0030] When in use, place the door ring on the two sets of clamping blocks 3 below, hold it with your hand, and then start the cylinder 7. Its output end drives the rectangular plate 5 to move down through the U-shaped adapter 6 (force is received in the middle and force is transmitted symmetrically at both ends). The extension columns 8 on both sides of the rectangular plate 5 are guided along the top of the clamping frame 1 to prevent the rectangular plate 5 from swaying. When the rectangular plate 5 moves down, the active blocks 41 of the two fixed rods 4 push the driven blocks 32 of the left and right guide posts 31 through the inclined plane cooperation, so that the left and right clamping blocks 3 move towards the center at the same time. At the same time, the upper clamping block 3 moves down with its own guide post 31, and works with the left and right clamping blocks 3 to complete the three-way clamping of the door ring in the upper, left and right directions. There is no response difference of the multiple cylinders 7, which ensures the door ring is subjected to balanced force. After processing, cylinder 7 drives rectangular plate 5 to move upward. The compressed springs 33 on the upper and left and right guide posts 31 release potential energy, causing the corresponding clamping blocks 3 to automatically reset. The lower clamping block 3 remains fixed, releasing the door ring. The entire process requires no additional drive. The rubber partition of the V-shaped clamping block 3 protects the surface of the door ring, achieving efficient and low-damage clamping operation.

[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.
