[0001] This utility model relates to the field of mechanical assembly tooling technology, specifically to a simple and convenient TVD assembly tooling. Background Technology

[0002] Currently, the assembly fixtures for TVDs (torsional vibration dampers) typically employ traditional fixed clamps or manual adjustment devices. These fixtures usually consist of multiple components, have complex structures, and require multiple adjustments and fixations during assembly, making the operation cumbersome.

[0003] In the existing technology, common assembly fixtures include hydraulic, pneumatic or mechanical clamps. Although they can complete the assembly task of TVD, they have certain limitations in terms of ease of operation, assembly efficiency and applicability. Summary of the Invention

[0004] The purpose of this utility model is to provide a simple and convenient TVD assembly fixture, which aims to solve at least one of the technical problems existing in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A simple and convenient TVD assembly fixture includes a lower mold base and an upper mold base. A lower base plate is fixedly installed on the lower mold base. A guide positioning mechanism and a locking mechanism driven by a nitrogen spring are also provided between the lower mold base and the upper mold base. The guide positioning mechanism is located at the center of the upper mold base and the lower mold base and is used to correct the coaxiality. The locking mechanism is located at the bottom of the upper mold base and is used to drive the upper mold base and the lower mold base to close the mold, thereby completing the TVD assembly.

[0007] As a further embodiment of this utility model: the guiding and positioning mechanism includes a central core shaft and a guide ring, the bottom end of the central core shaft is fixedly embedded in the center of the lower base plate, and the guide ring is slidably sleeved on the outer periphery of the central core shaft.

[0008] As a further embodiment of this utility model: the locking mechanism includes a nitrogen spring, a connecting sleeve, a pressure ring, and a pressure plate. The nitrogen spring and the connecting sleeve are both disposed in the upper mold base and are fixedly connected to the pressure ring. The pressure plate is fixedly disposed between the pressure ring and the guide ring.

[0009] As a further embodiment of this utility model: an assembly ring is also provided at the bottom of the upper mold base, and the lower section of the assembly ring is fixedly disposed between the guide ring and the pressure plate.

[0010] As a further embodiment of this utility model: the bottom end faces of the pressure plate, the assembly ring, and the guide ring are located on the same horizontal plane.

[0011] As a further embodiment of this utility model: the nitrogen spring drives the upper mold base and the lower mold base to perform a mold closing action, and the pressure plate completes the rapid locking and releasing.

[0028] Please refer to Figures 1-3. This utility model embodiment provides a simple and convenient TVD assembly fixture, including a lower mold base 1, an upper mold base 2, a guide positioning mechanism 4, a locking mechanism 5, and an assembly ring 6.

[0029] As shown in Figure 1, the lower mold base 1 is the basic support component, detachably fixed to the assembly machine, providing overall stability for the TVD assembly fixture. A lower base plate 3 is fixedly installed on the lower mold base 1. The lower base plate 3 is used to place the product skeleton 7 (such as the metal skeleton 7 of the TVD). The lower base plate 3 serves as the assembly reference surface and must ensure flatness to control positioning accuracy. The top of the lower base plate 3 has a reference surface with a flatness ≤0.05mm. The lower mold base 1 and the upper mold base 2 are also equipped with a guide positioning mechanism 4 and a locking mechanism 5. The guide positioning mechanism 4 is located at the center of the upper mold base 2, lower mold base 1, and lower base plate 3, used to correct coaxiality. The locking mechanism 5 is located at the bottom of the upper mold base 2 and is used to drive the upper mold base 2 and lower mold base 1 to close, completing the TVD assembly.

[0030] Please refer to Figure 2. In this embodiment, the guiding and positioning mechanism 4 includes a central spindle 41 and a guide ring 42. The bottom end of the central spindle 41 is fixedly embedded in the center of the lower base plate 3, and the guide ring 42 is slidably sleeved on the outer periphery of the central spindle 41. The central spindle 41 is the core positioning component, used to fix the guide ring 42 and the frame 7 to ensure the coaxiality of the assembly.

[0031] Referring to Figure 1, in this embodiment, the locking mechanism 5 includes a nitrogen spring 51, a connecting sleeve 52, a pressure ring 53, and a pressure plate 54. The nitrogen spring 51 and the connecting sleeve 52 are both disposed in the upper mold base 2 and are fixedly connected to the pressure ring 53. The pressure plate 54 is fixedly disposed between the pressure ring 53 and the guide ring 42. The bottom end faces of the pressure plate 54, the assembly ring 6, and the guide ring 42 are located on the same horizontal plane.

[0032] Nitrogen spring 51 provides a stable and controllable pressure source. It drives the upper mold base 2 and lower mold base 1 to achieve mold closing, and the pressure plate 54 facilitates rapid locking and releasing. Compared to mechanical springs, it offers a more linear pressure output, meeting the requirements of precision assembly. Connecting sleeve 52 connects the upper mold base 2 and the central spindle 41, transmitting pressure and assisting in guidance. Pressure ring 53 cooperates with guide ring 42, applying uniform pressure during mold closing to ensure the coaxiality of the product skeleton 7 and the rubber components. Pressure plate 54, driven by nitrogen spring 51, applies vertical pressure, pressing the product to complete assembly.

[0033] Preferably, an assembly ring 6 is also provided at the bottom of the upper mold base 2, and the lower section of the assembly ring 6 is fixedly disposed between the guide ring 42 and the pressure plate 54. The assembly ring 6 is an auxiliary positioning and sealing component, and the rubber component is driven into the middle of the skeleton 7 by pressure to realize assembly.

[0034] Preferably, the bottom plate 3 is provided with a guide groove 31 at the top, and the guide groove 31 and the guide ring 42 form a radial positioning.

[0035] The TVD assembly fixture of this utility model has a total weight of ≤10kg, is made of high-strength aluminum alloy, has an assembly accuracy of ±0.1mm, and a locking time of ≤1.5 seconds.

[0036] When using this utility model:

[0037] Fix the lower mold base 1 to the assembly machine to ensure it is level and rigid.

[0038] The TVD frame 7 is placed in the guide groove 31 of the bottom plate 3, and the guide ring 42 is inserted into the central mandrel 41 to complete the radial positioning of the frame 7.

[0039] The upper mold base 2 is driven to move downward, and the upper and lower molds are guided and closed through the cooperation of the connecting sleeve 52 and the pressure ring 53.

[0040] Nitrogen spring 51 pushes pressure plate 54 to apply vertical pressure to the product, fixing the frame 7 in place. Then, it drives assembly ring 6 to squeeze the rubber parts into the gap of frame 7 for pressing.

[0041] During the pressing process, the pressure ring 53 and the guide ring 42 automatically correct coaxiality deviation through the annular contact surface to avoid eccentricity problems.

[0042] After assembly is completed and pressure is maintained for a certain period of time, nitrogen spring 51 returns to its original position, upper mold base 2 rises, and the assembled TVD product is removed.

[0043] The mold closing action is driven by a nitrogen spring 51. Specific steps include:

[0044] Nitrogen spring 51 pushes the upper mold base 2 downward through connecting sleeve 52, gradually closing with the lower mold base 1;

[0045] The guide ring 42 is inserted into the guide groove 31 of the lower base plate 3 along with the central core shaft 41 to ensure that the upper and lower molds are radially aligned;

[0046] When the upper mold base 2 contacts the TVD skeleton 7, the nitrogen spring 51 continues to output linear pressure, causing the pressure plate 54 to press the skeleton 7, while the assembly ring 6 squeezes the rubber parts into the gap of the skeleton 7.

[0047] The nitrogen spring 51 maintains a constant pressure for 5 seconds to ensure that the assembled parts fit together fully.

[0048] Compared to traditional mechanical springs, nitrogen spring 51 provides stepless pressure during mold closing, avoiding impact vibration, and has no fatigue decay over long-term use, significantly improving mold closing stability and lifespan.

[0049] The preferred embodiments of this utility model have been described in detail above and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
