Description

Technical Field

[0001] The utility model relates to a valve body assembly platform, in particular to a rotary assembly platform for an electro-hydraulic valve body. Background Art

[0002] When assembling the electro-hydraulic valve body, the end covers need to be installed on the positive and negative ends in sequence. When assembling, the valve body needs to be placed on the operating table first, and the end cover on one side needs to be installed first, and then the end cover on the other side needs to be installed. The ordinary clamp used in the early stage can only fix the valve body. After installing the positive end cover, the valve block is removed from the tooling, and the valve body is manually picked up and rotated 180° and placed on the clamp, the clamp is clamped, and then the second end cover is installed. There are several problems with this installation method: 1) The valve body needs to be clamped every time it is installed, which wastes time and manpower; 2) The valve body is relatively heavy, and it wastes physical strength to pick it up and put it down repeatedly; 3) The clamp is not clamped or the valve body falls when it is moved, which may pose a safety hazard. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a rotary assembly platform for an electro-hydraulic valve body which can rotate the valve body to facilitate the installation of an end cover, and can effectively position the valve body during installation to ensure stable installation of the end cover.

[0004] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a rotating assembly platform for an electro-hydraulic valve body, comprising a fixed base plate, a rotating platform and a rotating positioning mechanism, the rotating platform being horizontally rotatably arranged on the fixed base plate, at least two installation stations being arranged side by side on the rotating platform, a plurality of groups of positioning pin holes being arranged at the bottom of each installation station according to a preset position, positioning grooves being symmetrically arranged at both ends of the rotating platform, the rotating positioning mechanism comprising an elastic reset positioning pin and a driving mechanism, the elastic reset positioning pin being elastically extended in the direction of the rotating platform when in a reset state, when one of the positioning grooves is rotated to be aligned with the elastic reset positioning pin, the elastic reset positioning pin is elastically inserted into the positioning groove and positions the rotating platform, and the driving mechanism is used to pull the elastic reset positioning pin outward until it is disengaged from the positioning groove.

[0005] Compared with the prior art, the utility model has the advantages that during installation, the locating pins of the electro-hydraulic valve body to be installed are inserted into the locating pin holes of the corresponding group on the rotating platform, and the holes on the bottom surface of the electro-hydraulic valve body are aligned with the locating pins and then the valve body is lowered to fix. At least two installation stations are arranged side by side on the rotating platform, and at least two electro-hydraulic valve bodies can be fixed at the same time, which is convenient to operate and reduces the labor intensity of workers; the elastic reset locating pin is elastically inserted into the locating groove to realize the positioning of the rotating platform when installing the end cover, and when the end cover on the other side needs to be installed, it is only necessary to pull the elastic reset locating pin outwards through the driving mechanism until it is disengaged from the locating groove, and the rotating platform can be rotated until the other locating groove is aligned with the elastic reset locating pin, and at this time, the driving mechanism is released to insert the elastic reset locating pin into the locating groove to position the rotating platform, and the installation of the end cover on the other side of the electro-hydraulic valve body is started; during the installation of the end cover, the position of the valve body is fixed, the operation is more convenient, the work efficiency is improved, and the product processing quality can be effectively improved, and the safety and reliability are high; when installing the end covers on both sides of the electro-hydraulic valve body, it is only necessary to rotate the rotating platform 180°, which saves a lot of time and manpower.

[0006] The driving mechanism comprises a pulling rod, a fixing rod, a rotating connecting block, a positioning block and a reset spring. The positioning block is fixedly arranged on the fixing base plate and located on one side of the rotating platform. The fixing rod is vertically fixedly arranged on one side of the fixing base plate. One end of the pulling rod is horizontally rotated and arranged on the fixing rod. One end of the rotating connecting block is horizontally rotated and connected to the rod body of the pulling rod. The other end of the rotating connecting block is horizontally rotated and connected to one end of the elastic reset positioning pin. An elastic reset cavity is horizontally arranged inside the positioning block. The other end of the elastic reset positioning pin passes through the elastic reset cavity and extends out of the other end of the positioning block. A limiting ring is arranged on the part of the other end of the elastic reset positioning pin located in the elastic reset cavity. The reset spring is sleeved on the elastic reset positioning pin and elastically compressed and arranged between one end of the elastic reset cavity and the limiting ring. When the pulling rod is rotated outward, the rotating connecting block is driven to move outward and the elastic reset positioning pin is pulled outward, so that it is disengaged from the positioning groove. When the pulling rod is released, the reset spring pushes the limiting ring to make the elastic reset positioning pin elastically extend inward from the positioning block.

[0007] The other end of the pulling rod is fixedly provided with an operating handle, so the pulling operation is more stable and convenient to use.

[0008] The middle part of the rotating platform is rotatably connected to the fixed bottom plate via a fixed rotating shaft. BRIEF DESCRIPTION OF THE DRAWINGS
