Technical Field

[0001] The utility model relates to the technical field of cleaning agent storage, in particular to a floating support positioning mechanism. Background Art

[0002] During the machining of a car engine, there is a process that requires pressure testing of the engine cavity to check whether there is a liquid leakage phenomenon in the engine cavity. In the inspection process of the engine cavity, it is necessary to position and support the engine cavity through a support positioning mechanism. After positioning, the double-acting cylinder on the opposite side moves to press the engine cavity tightly, and then the oil cylinder above presses down to seal all the channels of the engine for pressure testing. This is the airtightness test of the engine.

[0003] Currently, in the existing technology, single-point support is used at the outer conical surface of the engine cavity; for the positioning of the engine, the engine cavity is pushed to a certain position by a double-acting cylinder, and then the push rod is locked by a standard hydraulic support element. Although it can be positioned in this way, the single-point support is very unstable and often requires repeated attempts several times to succeed, which is time-consuming and laborious.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-3 , this application proposes a floating support and positioning mechanism, including an installation bracket 1 for installing at a specified position of the engine dry cavity airtightness test equipment. The left side of the lower end of the installation bracket 1 is fixedly installed with an installation base 2 through a bolt 3. The left end of the installation base 2 is fixedly installed with a hydraulic support 4, and a plunger push rod 41 is in the middle. The hydraulic support 4 can be connected to an external hydraulic device. A double-acting cylinder 5 is provided corresponding to the push rod 41 on the right side of the installation bracket 1. The double-acting cylinder 5 is fixed on the right side of the installation base 2. A relief groove is provided on the installation bracket 1 corresponding to the double-acting cylinder 5. The piston rod of the double-acting cylinder 5 can push the push rod 41 to move horizontally. A fixed plate 6 is provided at the left end of the push rod 41. The middle part of the fixed plate 6 is fixedly connected to the push rod 41, and the push rod 41 is perpendicular to the fixed plate 6. A floating plate 7 is movably provided on the left side surface of the fixed plate 6. At least two stop press heads 8 are fixedly provided on the left side surface of the floating plate 7. In this embodiment, preferably two, which are symmetrically arranged on the upper and lower sides of the left side surface of the floating plate 7. The two stop press heads 8 are perpendicular to the floating plate 7.

[0021] Specifically, the double-acting cylinder 5 pushes the push rod to move. The push rod 41 drives the fixed plate 6 and the floating plate 7 to move together. When both of the two stop press heads 8 contact the outer surface of the engine cavity, that is, when the floating plate 7 reaches the specified position, the hydraulic support 4 cooperates with the external hydraulic device to lock the push rod 41, so as to quickly complete the support and positioning work on the outer surface of the engine cavity and improve the work efficiency. The hydraulic support 4 in this application is a conventional component in the prior art and will not be elaborated here.

[0022] Furthermore, please refer to Figures 1-3, at the upper and lower ends of the left side of the floating plate 7, hollow floating joints 71 are horizontally provided. At the upper and lower ends of the floating plate 7, insertion holes 72 are horizontally opened. The floating joints 71 pass through the insertion holes 72, and bolts 3 pass through the hollow parts and are fixed on the fixed plate 6. The left end of the floating joint 71 can be clamped at the insertion holes 72. By fixing the floating joint 71 on the fixed plate 6, a gap is formed between the fixed plate 6 and the floating plate 7. At the positions corresponding to the two floating joints 71 in the gap, rectangular compression springs 73 are provided. The rectangular compression springs 73 are sleeved on the floating joints 71;

[0023] At the same time, the left end of the floating joint 71 is tapered. The shape of the insertion hole 72 is adapted to the structure of the floating joint 71, and the inner diameter is larger than that of the floating joint 71;

[0024] Specifically, the double-acting cylinder 5 pushes the push rod 41 to move. The push rod 41 drives the fixed plate 6, the floating plate 7, etc. to move together. When both of the two stop heads 8 contact the outer surface of the engine cavity, the rectangular compression spring 73 is compressed. At the same time, the inner diameter of the insertion hole 72 is larger than that of the floating joint 71, so that there is also a gap between the floating joint 71 and the insertion hole 72, which enables the floating plate 7 to swing appropriately up and down and left and right around the floating joint, so that the stop heads 8 can smoothly abut against the irregular outer surface of the engine cavity.

[0025] Further, please refer to Figures 1-3 , a positioning screw 42 is provided at the left side of the fixed plate 6 corresponding to the push rod 41, and a stop pin 74 that can abut against it is provided at the left side of the floating plate 7 corresponding to the positioning screw 42, which is convenient for the oil pressure support 4 to lock the floating plate 7 after abutment.

[0026] Further, please refer to Figures 1-3 , on the left side of the mounting bracket 1, guide sleeves 11 are horizontally provided on the front and rear sides of the mounting seat 2. The guide sleeves 11 are fixedly connected to the mounting bracket 1 by bolts 3. Corresponding to the two guide sleeves 11 on the left side of the fixed plate 6, guide rods 12 are horizontally provided. The guide rods 12 are fixed on the fixed plate 6 by bolts 3. The right end of the guide rod 12 is inserted into the guide sleeve 11 and is slidably connected thereto. The sliding fit between the guide rod 12 and the guide sleeve 11 prevents the fixed plate 6 from rotating during the movement, ensuring accurate positioning of the stop heads 8.

[0027] During use, the floating plate 7 is installed at the designated position of the engine dry cavity airtightness test equipment, and the mounting bracket 1 is fastened with bolts. After the engine cavity is sent to the designated position of the engine airtightness test equipment, the double-acting cylinder 5 is started to push the push rod 41 to move. The push rod 41 drives the fixed plate 6 and the floating plate 7 to move together. When both of the two stop heads 8 contact the specified position on the outer surface of the engine cavity, the oil pressure support 4 cooperates with the external hydraulic equipment to lock the push rod 41, so as to quickly complete the support and positioning work on the outer surface of the engine cavity.
