[0018] It is easy to understand that according to the technical solution of the present utility model, without changing the essence of the present utility model, those of ordinary skill in the art can propose various structural forms and implementation manners that can be mutually replaced. Therefore, the following detailed description of the embodiments and the drawings are only illustrative of the technical solution of the present utility model, and should not be regarded as the whole of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0019] The following will combine the specification append Figures 1-3 and the specific embodiments to describe the above technical solutions in detail:

[0020] A mounting and positioning device for a diesel engine balancer provided by the utility model includes a bottom plate 1. An installation groove 2 is formed on the upper surface of the bottom plate 1. A balancer is placed in the installation groove 2. Threaded grooves communicating with the installation groove 2 are formed on the end faces of both ends of the bottom plate 1 in the direction of the installation groove 2, and adjusting bolts 3 are threadedly connected thereto. The head of the adjusting bolt 3 is located outside the bottom plate 1, and its end is located in the installation groove 2. Four symmetrically arranged positioning holes 4 are formed on the bottom plate 1, and the positioning holes 4 are used to align with the installation parts of the diesel generator. A clamping mechanism matching with the installation groove 2 is arranged on the bottom plate 1. During installation, the bottom plate 1 is placed above the diesel generator, so that the positioning holes 4 on the bottom plate 1 can be aligned with the installation holes at the installation parts of the diesel generator and fixed by bolts. Then, the balancer is placed in the installation groove 2 on the bottom plate 1. Subsequently, the position of the balancer in the installation groove 2 is adjusted by the two adjusting bolts 3 to make it reach the precise installation position. Specifically, by rotating the two adjusting bolts 3 forward or backward respectively, the adjusting bolts 3 can make telescopic movements relative to the bottom plate 1. At this time, the end of a single adjusting bolt 3 contacts the balancer, thereby pushing the balancer to a suitable position. Finally, the ends of the two adjusting bolts 3 will both abut against the two ends of the balancer for preliminary fixation. Subsequently, the balancer is further clamped and fixed by the clamping mechanism.

[0021] As a preferred solution, the clamping mechanism includes a fixed block 5, a movable block 6 and a clamping bolt 7. The fixed block 5 is fixed on the bottom plate 1. The movable block 6 is slidably connected to the bottom plate 1 and connected to the fixed block 5 by the clamping bolt 7. When the balancer is placed in the placement groove 2, the side of the balancer is abutted against the fixed block 5. When the balancer is clamped and fixed, the clamping bolt 7 is rotated to make the movable block 6 move towards the fixed block 5 until the balancer is clamped.

[0022] As a preferred solution, an anti-slip pad 8 is arranged in the installation groove 2 on the bottom plate 1 to increase the friction between the balancer and the bottom plate 1 and prevent sliding.

[0023] As a preferred solution, a rubber pad 9 is fixedly connected to the end of the adjusting bolt 3 to avoid damaging the surface of the balancer.

[0024] Considering that the installation parts of some generators are located on the side, as a preferred solution, a positioning plate 10 is detachably and fixedly connected to the bottom plate 1. The positioning plate 10 is vertically fixed to one end of the bottom plate 1, and positioning holes 4 are formed thereon. When installing the balancer on this type of diesel generator, the positioning plate 10 is fixed on the bottom plate 1 so that the positioning holes 4 thereon can be aligned with the installation holes on the diesel generator and fixed by bolts.

[0025] In order to adapt to diesel generators of different specifications and models, as a preferred solution, the bottom plate 1 and the positioning plate 10 are both composed of two support plates 11 spliced together. A sliding groove 12 is formed on the opposite side of the two support plates 11, and a sliding plate 13 is slidably connected between the two sliding grooves 12. Before installation, the distance between the two support plates 11 is adjusted through the sliding plate 13 and the sliding groove 12, so as to adjust the overall length of the bottom plate 1 to adapt to diesel generators of different specifications and models. It should be noted that the fixed block 5 and the movable block 6 are arranged on one of the support plates 11.

[0026] In order to better carry out the length adjustment work, as a preferred solution, fixing grooves 15 are formed on both sides of the support plate 11. The fixing grooves 15 are communicated with the sliding grooves 12, and a fixing bolt 16 is threadedly connected in the fixing grooves 15. After the adjustment is completed, the fixing bolt 16 is tightened so that the fixing bolt 16 can contact and fix the sliding plate 13.

[0027] It should be noted that it can achieve the effect when the balancer is installed above or on the side of the diesel generator through the bottom plate.

[0028] The bottom plate mainly plays the role of supporting, fixing and positioning the balancer. As long as the design of the bottom plate can ensure that the balancer is in the correct position after installation and can effectively transmit the balancing force generated by the balancer, the expected balancing effect can be achieved. The function of the balancer is to offset the unbalanced forces and torques generated during the operation of the diesel generator, reduce vibration and noise, and improve the operation stability. As long as its installation position is reasonably designed and calculated to effectively balance the inertial forces and inertial torques generated by the rotating components, the expected effect can be achieved. The key lies in that the parameters such as the mass distribution, installation angle and position of the balancer need to match the structure and operating characteristics of the diesel generator to ensure a good balancing effect during operation.

[0029] It should be noted that the structure and performance of the bottom plate need to be carefully designed and tested to ensure its strength, stiffness and stability, so as not to affect the function of the balancer and ensure the smooth operation of the diesel generator.

[0030] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, etc. that are mature in the prior art, and will not be elaborated here. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] The technical scope of the present utility model is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present utility model, and these deformations and modifications shall fall within the protection scope of the present utility model.
