Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts manufacturing, in particular to a counterweight casting with adjustable size. Background Art

[0002] A ballast weight casting is a metal product made through a casting process, the main purpose of which is to provide additional weight to an object. The casting process usually involves pouring molten metal (such as cast iron, cast steel, etc.) into a specific mold. After cooling and solidification, a ballast weight with the desired shape and weight is formed. These ballast weights can have a variety of shapes, such as rectangular, cylindrical, irregular shapes, etc. The specific shape depends on its application scenario and the required ballast method;

[0003] Existing adjustable weights often use a relatively simple combination or addition / subtraction method to change weight. For example, some achieve weight adjustment by attaching or removing several small, fixed-weight weights from a base weight. This method, similar to a simple stack of weights, provides a fixed adjustment step size and a relatively crude adjustment method, far from meeting the weight balancing requirements of a vehicle.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1 to 4 As shown, a size-adjustable counterweight 22 casting includes a mounting frame 1, a clamping assembly 2 is provided on the mounting frame 1, and the clamping assembly 2 includes a counterweight 22. The counterweight 22 is slidably connected to the mounting frame 1, and a fixing rod 21 is slidably connected to the mounting frame 1. Sliding openings are formed on both the fixing rod 21 and the counterweight 22.

[0029] The clamping assembly 2 also includes a sliding frame 26, which is slidably connected to the sliding frame 26 with a second rotating shaft 25, and the second rotating shaft 25 is fixedly connected to the clamping rod 24. The end of the clamping rod 24 away from the sliding frame 26 is fixedly connected to the sliding rod, the mounting frame 1 is fixedly connected to a transmission frame 28, and the transmission frame 28 is fixedly connected to a transmission shaft 29, and the transmission shaft 29 is slidably connected to the clamping rod 24, the mounting frame 1 is fixedly connected to an electric telescopic rod 27, and the electric telescopic rod 27 is fixedly connected to the sliding frame 26, and the counterweight block 22 is rotatably connected to the first rotating shaft 23.

[0030] In the utility model, the sliding frame 26 is driven to rise by the electric telescopic rod 27, which drives the clamping rod 24 and the sliding rod to work in coordination with the counterweight block 22. The first rotating shaft 23 is used to rotate the counterweight block 22 and pull it up to achieve fine adjustment. At the same time, the fixing rod 21 can be inserted into the fastening block to achieve a large increase or decrease in weight. The combination of the two avoids the rough adjustment of the traditional fixed step length and accurately meets the high-precision requirements of automobile parts for counterweights under different working conditions.

[0031] Further, such as Figures 1 to 4 As shown, a sliding hole is provided on the side of the counterweight 22 close to the clamping rod 24, and a sliding groove is provided on the mounting frame 1. The sliding rod on the clamping rod 24 is slidably connected to the sliding hole of the mounting frame 1. By providing sliding holes on the clamping rod 24 and the counterweight 22, the sliding rod can be inserted into the sliding hole on the counterweight 22 when in use.

[0032] The installation frame 1 is fixedly connected to the limit frame 3, and the counterweight 22 is slidably connected to the limit frame 3. By providing the limit frame 3, the counterweight 22 can be prevented from falling off.

[0033] The sliding frame 26 is provided with a snap-in slot, and the second rotating shaft 25 is slidably connected to the snap-in slot on the sliding frame 26. By providing the snap-in slot on the sliding frame 26, when in use, the second rotating shaft 25 can be connected to or taken out of the snap-in slot according to actual needs.

[0034] A sliding groove is provided on the clamping rod 24 , and the transmission shaft 29 is slidably connected in the sliding groove on the clamping rod 24 . By providing the sliding groove, the transmission shaft 29 can slide in the clamping rod 24 during use to realize transmission of the clamping rod 24 .

[0035] In the above solution, there is still an unclear reason why the clamping rod 24 drives the sliding rod to clamp inward, such as Figure 1 As shown, the mounting frame 1 is configured to be triangular. By configuring the mounting frame 1 to be triangular, when in use, when the transmission frame 28 slides upward, the sliding rod on the clamping rod 24 is driven to be inserted into the counterweight 22 .

[0036] Working principle: Figures 1 to 4 As shown, before use, slide the clamping rod 24 into the sliding frame 26, and fix the sliding frame 26 to the automobile parts that need to be adjusted in weight;

[0037] When in use, by inserting the fastening block on the fixing rod 21, the fixing rod 21 and the counterweight block 22 can be fixed, and the weight can be increased or decreased;

[0038] Afterwards, the electric telescopic rod 27 is started, causing the sliding frame 26 to rise, so that the clamping rods 24 arranged on both sides of the mounting frame 1 slide on the transmission frame 28, so that the ends of the two clamping rods 24 away from the sliding frame 26 drive the sliding rods on the clamping rods 24 to slide onto the counterweight block 22. Afterwards, as the electric telescopic rod 27 continues to rise, the sliding rods on the clamping rods 24 gradually pull up the counterweight block 22. Due to the setting of the first rotating shaft 23, the counterweight block 22 will rotate and be gradually lifted up by the clamping rods 24, thereby achieving fine adjustment of the weight.

[0039] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments with equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
