Description

Technical Field

[0001] The utility model relates to the technical field of engine manufacturing, in particular to a general engine cylinder block support bench. Background Art

[0002] The engine cylinder block is the main part of the engine, a key component connecting each cylinder and the crankcase, and also a support frame for installing components and accessories such as pistons and crankshafts. It can be seen that the structure and function of the engine cylinder block are crucial for the overall performance and operation of the engine and it is one of the core components of the engine.

[0003] Currently, during the manufacturing process of the engine cylinder block, it needs to be placed on a support bench, and the support bench is mainly applied in the following two scenarios: First, after the engine cylinder block is cast, subsequent processing such as polishing, rust prevention, finish machining of casting holes and grooves, and forming machining of non-casting holes and grooves is required. During the subsequent processing after the engine cylinder block is forged, it is necessary to ensure the stable fixation of the engine cylinder block and make the surface or part to be processed in a suitable high, low position and orientation for processing. For this purpose, a specific support bench needs to be configured for the engine cylinder block to provide stable support. Second, during the inspection and maintenance of the engine cylinder block, it is also necessary to make the inspection part in a suitable high and low position and orientation for inspection.

[0004] Although the existing support benches can play a role in supporting the engine cylinder block, there are still the following deficiencies in actual use: The support bench is a dedicated bench and does not have universality. A support bench of one specification can only be applicable to an engine cylinder block of one specification. Therefore, different support benches need to be configured for different processing and maintenance operations, which not only increases the manufacturing cost of the tooling fixture but also occupies more workshop space. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of lack of universality, high manufacturing cost and much occupied space in the prior art, and provide a general engine cylinder block support bench, which is reasonably designed, simple and ingenious in structure, has high stability, has universality, can not only adapt to engine cylinder blocks of different specifications, but also save manufacturing cost and workshop space, and is suitable for popularization.

[0006] The utility model is realized by the following technical scheme: A general engine cylinder block support bench includes a base, and a plurality of telescopic arms for supporting the engine cylinder block are arranged on the top side of the base. The top end of the telescopic arm is connected with a universal mechanism, the bottom end of the telescopic arm is slidably connected with the top side of the base, and a plurality of feet for supporting the engine cylinder block are evenly spaced on the universal mechanism.

[0007] A further improvement of the present utility model is that several parallel and evenly spaced guide rails are fixed on the top side of the base, and a slider that is slidably matched with the guide rails is connected to the bottom end of the telescopic arm. The telescopic arm is slidably connected to the guide rails through the slider.

[0008] A further improvement of the present utility model is that the telescopic arm includes an upper section cylinder and a lower section pipe body. The upper section cylinder is screwed to the lower section pipe body to form a telescopic structure. The top end of the upper section cylinder is connected to the universal mechanism, and the bottom end of the lower section pipe body is connected to the slider.

[0009] A further improvement of the present utility model is that the universal mechanism includes a ball head and a support seat. The ball head is fixed to the top end of the upper section cylinder. The top side of the support seat is used to install the support feet. A spherical groove that is matched with the ball head is opened on the bottom side of the support seat. The support seat is slidably matched with the ball head through the spherical groove to form a structure that can rotate in all directions.

[0010] A further improvement of the present utility model is that a retaining cover for positioning the ball head is arranged at the opening of the spherical groove. The retaining cover is fixed to the bottom side of the support seat by screws.

[0011] A further improvement of the present utility model is that the retaining cover includes a semi-circular retaining ring A and a semi-circular retaining ring B. The semi-circular retaining ring A and the semi-circular retaining ring B are spliced to form a complete retaining cover.

[0012] A further improvement of the present utility model is that three support feet are provided. The connection lines between the force application points at the top ends of the three support feet form an equilateral triangle structure.

[0013] A further improvement of the present utility model is that the support feet are arranged obliquely. The top ends of the support feet are inclined towards the outer side of the support seat. The bottom ends of the support feet are screwed to the top side of the support seat and fixed in position by nuts.

[0014] A further improvement of the present utility model is that a rubber buffer part is arranged at the top end of the support foot.

[0015] A further improvement of the present utility model is that six guide rails are provided, and four telescopic arms are arranged on each guide rail.

[0016] From the above technical solutions, the beneficial effects of the present utility model can be seen:

Through the telescopic arm and the sliding cooperation between the telescopic arm and the base, this support platform can adjust the height and position of the telescopic arm according to the structural shape of the bottom side of the engine cylinder block to select a suitable support point, that is, the universality is realized, and it can be applied to engine cylinder blocks of different specifications.

[0018] 2. Workers only need to be equipped with one support platform to adapt to engine rods of multiple specifications, saving manufacturing costs and workshop space.

[0019] 3. The universal mechanism of this support stand can rotate freely. The universal mechanism, in combination with three feet, can be applied to the surface of uncertain and irregular support points, thus greatly enhancing the stability of this support stand. BRIEF DESCRIPTION OF THE DRAWINGS
