Description

Technical Field

[0001] This utility model relates to a tooling fixture, and more specifically, to a vibration damping pad installation fixture. Background Technology

[0002] In construction machinery, vibration damping pads are needed for the installation of components such as engines, cabs, and transmissions. Vibration damping pads are typically T-shaped, with a hole in the center for bolts to pass through. The smaller diameter cylindrical section of the vibration damping pad is installed in the damping pad receiving hole of the support component, while the larger diameter cylindrical section of the vibration damping pad is clamped between the support component and the supported component.

[0003] Vibration damping pads are typically made of rubber elastic components. The diameter of the damping pad receiving hole on the support component, which accommodates the small-diameter cylindrical section of the damping pad, is smaller than that of the small-diameter cylindrical section of the damping pad. After assembly, the two are in an interference fit with a large amount of interference. Therefore, it is difficult to install the damping pad, even under lubrication. It requires a lot of pressure to install it, resulting in low efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is the difficulty in inserting the small-diameter cylindrical section of the vibration damping pad into the vibration damping pad receiving hole of the support member, and provides a vibration damping pad installation fixture.

[0021] Support component 1, vibration damping pad receiving hole 11, vibration damping pad 2, small diameter cylindrical section 21, tooling body 3, vibration damping pad receiving hole 31, screw 4, bolt head 41, radial through hole 42, nut 5, pressure plate 6, assist rod 7. Detailed Implementation

[0022] The specific implementation plan is described below with reference to the attached diagram.

[0023] like Figure 1 Figure 2 As shown, the vibration damping pad installation fixture is used to insert the small-diameter cylindrical section 21 of the T-shaped vibration damping pad 2 into the vibration damping pad receiving hole 11 of the support member 1. The vibration damping pad installation fixture includes a fixture body 3, a pressure plate 6, a nut 5, and a screw 4, etc.

[0024] One end of the tooling body 3 is used to abut against the support 1, and the radial dimension of this end is larger than the diameter of the damping pad receiving hole 11.

[0025] The pressure plate 6 is positioned on the side of the vibration damping pad away from the support member 1 and is sleeved with the screw 4 to press against the vibration damping pad 2; the vibration damping pad 2 is located between the support member 1 and the pressure plate 6. The nut 5 is threadedly connected to the screw 4 and abuts against the pressure plate 6.

[0026] One end of the screw 4 is axially limited and connected to the main body of the tooling 3, and the other end passes through the damping pad receiving hole 11, the bolt hole in the center of the damping pad 2, and the hole in the pressure plate 6 before being connected to the nut 5. When the nut 5 rotates relative to the screw 4 in a certain direction, the nut 5 pushes the pressure plate 6 to move, squeezing the damping pad 2 and inserting the small-diameter cylindrical section 21 of the damping pad 2 into the damping pad receiving hole 11 of the support 1. One end of the screw 4 is axially limited and connected to the main body of the tooling 3, that is, when the screw 4 rotates relative to the main body of the tooling 3 in a certain direction (e.g., clockwise), it cannot move axially.

[0027] In this embodiment, when installing the vibration damping pad 2, the T-shaped vibration damping pad 2 is placed on one side of the support member 1, and the end of the small-diameter cylindrical segment 21 of the vibration damping pad 2 is inserted into the vibration damping pad receiving hole 11 of the support member 1. The fixture body 3 is placed on the other side of the support member 1, and the threaded section of the screw 4 passes through the vibration damping pad receiving hole 11 of the support member 1, the bolt hole of the vibration damping pad 2, and the hole of the pressure plate 6 in sequence, and then is threadedly connected to the nut 5. At this time, the fixture body 3 is fixed, the nut 5 is rotated, and the nut 5 moves axially relative to the screw 4, and the vibration damping pad 2 is squeezed by the pressure plate 6, so that the small-diameter cylindrical segment 11 of the vibration damping pad 2 is squeezed into the vibration damping pad receiving hole 11 of the support member 1.

[0028] In this embodiment, when the pressure plate 6 pushes the vibration damping pad 2, the screw 4 passes through the bolt hole of the vibration damping pad 2. The screw 4 can play a guiding and fixing role. The vibration damping pad 2 will not deviate during the extrusion and pushing process. The entire process is stable, efficient and labor-saving by rotating the nut 5 to push it forward.

[0029] Optionally, a radial through hole 42 is provided on the portion of the screw 4 protruding from the tooling body 3, and an assist rod 7 is installed in the radial through hole 42. It is necessary to prevent the screw 4 from rotating when rotating the nut 5. In this embodiment, the screw 4 can be prevented from rotating by holding the assist rod 7 or by making the assist rod 7 contact other components. The assist rod 7 acts as a lever, and only a small force is needed to prevent the screw from rotating.

[0030] To prevent the screw from rotating with the nut, a bolt head 41 can be designed on the part of the screw 4 that protrudes from the main body of the tooling. For example, it can be designed as a regular polygonal bolt head or a regular polygonal countersunk hole. When rotating the nut 5, a wrench can be used to fix the bolt head 41 of the screw 4.

[0031] Optionally, such as Figure 3 As shown, the fixture body 3 is a cylindrical structure closed at one end, with its open end abutting against the support member 1. The inner diameter of the open end is larger than the diameter of the damping pad receiving hole 11. The closed end of the fixture body 3 is connected to the screw 4. Optionally, the screw 4 is coaxially arranged with the fixture body 3.

[0032] Optionally, the screw 4 is fixedly connected to the tooling body 3. The screw 4 and the tooling body 3 can be an integral structure, welded, or fixedly connected by threaded locking. The screw 4 and the tooling body 3 can also be rotatably connected. For example, the tooling body 3 is provided with a screw hole for the screw 4 to pass through. The diameter of the portion of the screw 4 protruding from the tooling body 3 is larger than the diameter of the screw hole, and the screw 4 is rotatably connected to the tooling body 3.

[0033] This utility model provides a vibration damping pad installation fixture. By rotating the rotating nut, the small-diameter cylindrical section of the vibration damping pad can be squeezed into the receiving hole of the vibration damping pad by the pressure plate. The operation is simple, convenient and quick, and the work efficiency is high.
