During the assembly of the cross shaft assembly, the fixture needs to achieve stable positioning and clamping of components such as the cross shaft and the fixed seat, and at the same time cooperate with the assembly action to complete the precise docking of the components.

[0003] A patent document with publication number CN204935036U discloses a cross shaft assembly assembly fixture, including an upper pressure block, a lower pressure block, a top block, a fork-shaped component, a connecting rod, a cylinder, and a connecting component. The lower pressure block is connected to the lower pressure block, and the top block fits inside the upper pressure block. The top block is connected to the actuating end of the cylinder, and a connecting rod is connected to the bottom of the top block. The lower end of the connecting rod has a threaded hole, and a cross shaft fits into the threaded hole. A connecting component is located at the bottom of the lower pressure block, and a fork-shaped component is connected to the shaft end of the connecting component. The fork-shaped component has an ear hole in the middle, which mates with the connecting rod. Compared with the prior art, this utility model ensures the assembly quality of the cross shaft assembly and effectively reduces the labor intensity of operators.

[0004] The existing solutions and some existing cross shaft assembly jigs mentioned above still have shortcomings in the actual clamping and component removal process. Existing jigs lack elastic components that facilitate component removal after clamping. After the cross shaft assembly is assembled, due to the tight positioning fit between the jig and the component, the component is difficult to remove smoothly due to excessive clamping force or tight fit, which increases the number of operation steps. Therefore, this utility model proposes a cross shaft assembly assembly fixture to solve the above problems. Utility Model Content

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0016] Example 1: Please refer to Figures 1 to 2 A cross shaft assembly assembly fixture includes a base 1, a cross shaft 2, and a fixing plate 3. A fixing seat 4 is mounted on the base 1, the cross shaft 2 is mounted on the fixing seat 4, and the fixing plate 3 is disposed on the fixing seat 4. The sliding component 5, the snap-fit ​​component 6, and the elastic component 7 are provided. The sliding component 5 is disposed on the base 1, the snap-fit ​​component 6 is disposed on the sliding component 5, and the elastic component 7 is disposed on the sliding component 5.

[0017] The sliding assembly 5 has a mounting head 502 fixedly installed on the sliding seat 501. The sliding seat 501 is adapted to slide and snapped onto the base 1. The mounting head 502 is equipped with a mounting rod 503, and the mounting rod 503 is snapped with a cross shaft 2. The sliding seat 501 is driven by a motor inside the base 1.

[0018] In use, the fixing seat 4 is fixedly installed on the base 1, and the cross shaft 2 is placed on the mounting rod 503. After clamping, the fixing plate 3 can cover the fixing seat 4. The cross shaft 2 can be fixed by rotating the fixing plate 3. Start the motor in the base 1. The motor drives the sliding seat 501 in the sliding assembly 5 to slide along the base 1. Since the sliding seat 501 is adapted to the base 1 and slides and snaps together, there will be no deviation during the sliding process. At the same time, the mounting head 502 fixed on the sliding seat 501 moves synchronously with the sliding seat 501. The mounting rod 503 on the mounting head 502 also moves closer to the cross shaft 2. When the cross shaft 2 on the mounting rod 503 is assembled to the required position, the motor is turned off. At this time, the mounting rod 503 can assist the cross shaft 2 to accurately dock with other parts to be assembled, laying the foundation for subsequent assembly steps. The whole process is driven by the motor and there is no need for manual pushing of the sliding seat 501, which reduces the operation intensity and improves the positioning accuracy.

[0019] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The snap-fit ​​protrusion 601 in the snap-fit ​​assembly 6 is adapted to slide and snap-fit ​​in the snap-fit ​​groove 602. The snap-fit ​​groove 602 is set in the base 1, and the snap-fit ​​protrusion 601 is set at the bottom of the sliding seat 501.

[0020] The snap-fit ​​protrusion 601 in the snap-fit ​​assembly 6 is provided with a second protrusion 603, which is adapted to snap into the second slot 604. The snap-fit ​​protrusion 601 and the second protrusion 603 are arc-shaped.

[0021] During use, as the sliding seat 501 slides along the base 1, the snap-fit ​​protrusion 601 in the snap-fit ​​assembly 6 at the bottom of the sliding seat 501 simultaneously engages with the snap-fit ​​groove 602 in the base 1. Because the snap-fit ​​protrusion 601 and the snap-fit ​​groove 602 are compatible and slide together, their cooperation guides the sliding direction of the sliding seat 501, preventing lateral displacement during sliding. Simultaneously, the second protrusion 603 on the snap-fit ​​protrusion 601 moves with the snap-fit ​​protrusion 601 and gradually engages with the second slot 604 in the snap-fit ​​groove 602. The locking protrusion 601 and the second protrusion 603 are arc-shaped, which can reduce the frictional resistance during sliding and make the locking process smoother. When the sliding seat 501 moves to the target position, the second protrusion 603 is fully engaged in the second groove 604, and together with the locking protrusion 601, they form a double limit on the sliding seat 501, preventing the sliding seat 501 from being displaced due to external forces during assembly, further enhancing the stability of the sliding seat 501, and ensuring that the mounting rod 503 on the mounting head 502 can always be kept in the precise position of docking with the cross shaft 2, thus ensuring the assembly quality.

[0022] Example 3: Based on Example 2, please refer to... Figures 3 to 4The elastic protrusion 701 in the elastic component 7 is disposed on one end of the mounting rod 503, and an elastic layer 702 is uniformly disposed on the elastic protrusion 701.

[0023] The elastic protrusion 701 in the elastic component 7 is uniformly provided with springs 703, and a top plate 704 is provided inside the spring 703, with the spring 703 surrounding the top plate 704.

[0024] During use, when the mounting rod 503 drives the elastic protrusion 701 in the elastic component 7 to approach the cross shaft 2, the elastic protrusion 701 first contacts the inside of the cross shaft 2. Under the drive, the cross shaft 2 contacts the surface of the fixed seat 4. After contact, the elastic layer 702 on the elastic protrusion 701 deforms due to the contact pressure, which plays a buffering role for the component and avoids scratches or damage to the surface of the component caused by rigid contact. As the assembly action progresses, the elastic protrusion 701 is further compressed, and the spring 703 set in the top plate 704 inside it is compressed. The reaction force generated by the spring 703 makes the elastic protrusion 701 fit tightly against the cross shaft 2. The clamping mechanism enhances the clamping effect on the component, ensuring its stable position during assembly. After assembly, the reverse drive sliding seat 501 moves the mounting rod 503 away from the component. At this time, the spring 703 releases its elastic potential energy, pushing the top plate 704 to reset, which in turn drives the elastic protrusion 701 to return to its original shape. The pressure between the elastic protrusion 701 and the component gradually decreases. The separation force generated by the elastic deformation helps the component to smoothly detach from the clamp without the need for external tools, reducing operation steps. At the same time, it avoids deformation of the component due to uneven force during detachment, ensuring the integrity and accuracy of the component after assembly. 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.
