Description

Connecting rod weighing device

technical field

The utility model relates to the technical field of automobile manufacturing, in particular to a connecting rod weighing device.

Background technique

The connecting rod is an important part in the automobile engine. Due to the requirements of dynamic balance, its weight needs to be strictly controlled. In addition to the total weight requirement, the weight of the large and small ends must be measured separately to control the weight ratio of the large and small ends. Therefore, ordinary measuring instruments cannot meet the requirements. Its weighing requirements require the use of special measuring devices. In order to solve this problem, large-scale automobile manufacturing enterprises often design and manufacture special measuring devices by themselves. The structure of the device is relatively complicated and the cost is often around ten thousand yuan; High priced purchases.

4. The structure of this product is highly versatile, and it can be applied to different connecting rods by changing the fixing block and the center distance between the two.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is one of structural principle schematic diagrams of the utility model.

Fig. 2 is the second schematic diagram of the structure principle of the utility model.

Detailed ways

As shown in Fig. 1 and Fig. 2, it is a kind of connecting rod weight measuring device disclosed by the utility model, which includes an electronic scale, and two electronic scales 5 and 2 are arranged at intervals on the bottom plate 1, and the two electronic scales 5 The weighing pans of , 2 are respectively provided with fixed blocks 4, 3 that can support the connecting holes at the ends of the connecting rod 7. One of the fixed blocks 4 is larger than the other fixed block 3 . The bottom plate 1 is provided with a transverse chute, and the bottom of the electronic scale 5 is provided with a slider 7 that can slide in the chute. Chute is not shown in the figure, when there is slide block, the bottom of electronic scale is generally that mounting plate is installed, and the bottom of mounting plate is provided with slide block, certainly, also slide block 7 can be designed as pulley, so chute can be Without design, the pulley is directly made to slide on the base plate. Generally, only one of the electronic scales needs to be set to slide, of course, both of them can also be set to slide.

In the above, the fixed blocks 4 and 3 are cylinders or cones or truncated cones. The inclination of the side wall of the frustum is 4°-10°. Preferably, the inclination of the side wall of the frustum is 5°. The inclination of the side wall of the cone is 4°-10°. Preferably, the inclination of the side walls of the cone is 5°.

Choose two electronic scales with corresponding ranges according to the weight of the connecting rod. Arrange two electronic scales in parallel, keep an appropriate distance between them and fix them on the bottom plate with strong glue, or one of them can be set to slide on the bottom plate, the distance is to ensure that the two fixed blocks for positioning can be placed on the electronic scale. The center of the weighing pan of the scale is appropriate. Then two fixed blocks for positioning are bonded and fixed on the center of the weighing pan of the electronic scale with superglue to ensure that the dimension A between the two fixed holes in the accompanying drawing is consistent with the center distance between the large and small ends of the connecting rod.

The two fixed blocks are plastic parts in the shape of a truncated cone, which are respectively used to locate the large and small end holes on the connecting rod, and the taper size is preferably 5°. The diameter requirements are: the diameter of the cone bottom is slightly larger than the connecting rod hole, and the cone top is slightly smaller than the connecting rod hole.

The manufacturing method and steps of this embodiment are as follows:

(1) Prepare base plate blanks, position round tables, and purchase electronic balances;

(2) Calculate the size of the bottom plate;

(3) Cut the bottom plate according to size;

(4) Bond the fixed block to the center of the weighing pan of the electronic scale;

(5) Glue and fix the electronic scale on the bottom plate to ensure that the center distance between the two fixed blocks is consistent with the center distance between the large and small ends of the connecting rod;

(6) Operate the operation panel of the electronic scale to "tare" to ensure that the measurement result is not affected by the fixed block.

So far, this embodiment has been manufactured and adjusted, and can be used for measurement.

The usage method of this embodiment is as follows, as shown in Figure 2:

(1) Clean the surface of the electronic scale and the fixed block to ensure that it is clean and free of debris.

(2) Check the initial readings of both scales to make sure the "tare" operation has been performed.

(3) Place the connecting rod on the product. The large and small end holes of the connecting rod are set on the two fixed blocks respectively. distance rather than direct contact.

(4) Degrees on the electronic display.

The foregoing embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore: all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered by this utility model. within the scope of protection of utility models.
