Abstract
Description
Technical Field
[0001] This utility model relates to the field of cylinder block machining technology, and in particular to a novel cylinder block necking machining device. Background Technology
[0002] Currently, shock absorbers are easily worn parts in the process of car use. The quality of shock absorber operation directly affects the smoothness of car driving and the lifespan of other components. Therefore, shock absorbers should be kept in good working condition at all times.
[0003] refer to Figure 1 In the current assembly process of automobile shock absorbers, it is necessary to perform a necking process on the end of the cylinder body 1' away from the bottom cover 2' of the automobile shock absorber. However, the existing processing equipment often cannot maintain the coaxiality and concentricity of the necked end 3' with the cylinder body and has low working efficiency. Utility Model Content
[0004] Therefore, in view of the above problems, this utility model proposes a new cylinder shrinking processing device with fast processing speed, effective guarantee of coaxiality and concentricity between the shrinking end and the cylinder body, and high working efficiency.
[0005] To solve this technical problem, the present invention adopts the following solution: a novel cylinder block necking processing device, comprising a press, a base, two columns, a pressure rod, a sleeve, a necking mold, a guide ring, a slide block, and a connecting plate. The base is provided with positioning posts whose outer diameter matches the inner diameter of the cylinder block. The connecting plate is fixedly mounted on the top of the two columns, and the lower parts of the two columns are fixedly connected to the base on opposite sides of the positioning posts. The slide block is slidably fitted onto the two columns between the connecting plate and the base. The slide block has a through hole in its center, and the upper part of the sleeve is fixedly connected to the bottom of the slide block. The upper opening of the sleeve is connected to the through hole of the slide block. The bottom of the sleeve is provided with a hollow annular sleeve cover. The necking mold is embedded in the sleeve, and the lower part of the necking mold is an arc-shaped part that matches the pre-narrowed and bent part of the cylinder body. The guide ring is embedded in the sleeve between the necking mold and the hollow annular sleeve cover, and the inner diameter of the middle part of the guide ring matches the outer diameter of the cylinder body. The press head of the press is connected to the upper end of the press rod, which drives the press rod to press down or lift up. The press rod passes through the opening in the middle of the connecting plate and enters the sleeve through the through hole of the slide block. The free end of the press rod is connected to the upper end of the necking mold.
[0006] A further improvement is that the positioning post of the base is provided with multiple annular steps with gradually increasing outer diameters that match the inner diameters of different cylinder models, thus positioning different cylinder models.
[0007] Further improvements include a transverse unloading rod and two adjustable top rods. The transverse unloading rod is transversely inserted through the pressure rod and located in the middle of the connecting plate and the slide block, with both ends of the transverse unloading rod extending out of the pressure rod. The two adjustable top rods are respectively adjustablely inserted through the connecting plate, with the lower parts of the two adjustable top rods located above the two free ends of the transverse unloading rod.
[0008] A further improvement is that both adjustable top rods include bolts and nuts, with the bolts vertically inserted into the connecting plate and the length of the bolts extending downwards adjusted by the nuts.
[0009] In a further improvement, the pressure head and the pressure rod are connected by a floating connection mechanism.
[0010] In a further improvement, the guide ring has an arc-shaped chamfered ring at the end of its central opening facing the hollow annular cover.
[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: A positioning post is set on the base to vertically and axially position the end of the cylinder body away from the necking end. The necking mold and guide ring are embedded in the sleeve, and the sleeve is fixed to the slide. In use, the cylinder body without the bottom cover is simply placed on the positioning post. The press head drives the press rod downwards, which in turn drives the guide ring embedded in the sleeve on the slide to first move towards the end requiring necking. Then, the press rod drives the arc-shaped part of the necking mold to press the necking end of the cylinder body axially downwards to perform necking processing. The entire axial direction is pressed down simultaneously until the required necking length is reached. The guide ring and necking mold... With the cooperation of the tool, the cylinder body can be completed in one go for narrowing. The processing speed is fast, the coaxiality and concentricity of the narrowed end and the cylinder body are effectively guaranteed, and the working efficiency is high. Different annular steps are set on the positioning column to achieve positioning and narrowing processing of different models of cylinder bodies. By setting a transverse unloading rod and two adjustable top rods, after the processing is completed, the pressure rod is lifted and then impacted upward by the transverse unloading rod to generate vibration, which completes the automatic unloading of the cylinder body after narrowing processing, making it more convenient to use. The pressure head and pressure rod are connected by a floating connection mechanism, which can effectively ensure the coaxiality between the pressure head and the lower pressure rod, further enhance the coaxiality of the downward pressing power and increase the accuracy of cylinder body narrowing processing. It can be widely promoted and applied. Attached Figure Description
