In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.
As shown in fig. 2, a spring pressing tool with a large pre-pressure according to an embodiment of the present invention includes:
the mounting seat comprises a bottom plate 100, a fixing column 200 and a conducting rod supporting column 300, wherein the fixing column 200 and the conducting rod supporting column 300 are arranged on the bottom plate 100 in parallel and vertically;
the pressing device comprises a pressing rod 400 and a pressing sleeve 500, the head end of the pressing rod 400 is hinged to the fixing column 200, the pressing sleeve 500 is hinged to the rod body of the pressing rod 400, and a through conductive rod sleeve hole is formed in the pressing sleeve 500 in the axial direction.
As shown in fig. 3, in the schematic diagram of the spring pressing tool with large pre-pressure for assisting in assembling the spring, the conductive rod 100a is vertically placed on the conductive rod supporting column 300, the spring 200a is sleeved on the rod body of the conductive rod 100a, and then the conductive rod 100a is provided with the fixing sleeve 300 a.
The pressing sleeve 500 is sleeved on the conductive rod 100a, the pressure rod 400 is pressed downwards, the pressure rod 400 rotates around a hinged point with the fixed column 200, and the pressing sleeve 500 is driven to move downwards along the conductive rod 100a, so that the fixed sleeve 300a moves downwards to apply pressure to the spring 200 a. After the pressure rod 400 presses the spring 200a to a compression position corresponding to the pre-pressure, the spring can be bound and fixed by a rope or a steel wire rope, a hole is formed in the fixed sleeve 300a, and a positioning pin is installed for fixing. The pressure applied to the pressure rod 400 is then removed, and the compression sleeve 500 is removed, completing the assembly of the field spring 200 a. The whole assembly process utilizes the lever principle, greatly saves the force required to be applied during assembly, and is particularly suitable for the assembly of springs with larger pre-pressure.
Further, fixed column 200 is equipped with sliding sleeve 600, and the gliding suit is gone up and down on fixed column 200 in sliding sleeve 600, and the head end of depression bar 400 is articulated through rotating pin and sliding sleeve 600.
Because of the different specifications of the conducting rod, the spring 200a is pressed differently. The sliding sleeve 600 can be adjusted to the up-down position according to the length of the spring 200a, so that different requirements are met. After the position is adjusted in place, the sliding sleeve 600 is fixedly connected to the fixing column 200 through the bolt fastening and other modes. If only the spring 200a with the same specification needs to be installed in an auxiliary manner, the sliding sleeve 600 can be directly welded on the fixing column 200, or the pressing rod 400 is directly hinged with the body of the pressing rod 400. The pressing lever 400 rotates about the rotation pin during rotation.
The pressing sleeve 500 is hinged with the pressure lever 400 through a connecting plate 700, and two ends of the connecting plate 700 are respectively connected with the rod body of the pressure lever 400 and the pressing sleeve 500 through rotating pins. In the process of pressing down the pressure lever 400, the connecting plate 700 pulls the pressure sleeve 500 to move downwards, the rotation angle between the pressure sleeve 500 and the pressure lever 400 can be increased by hinging the pressure sleeve 500 and the pressure lever 400 through the connecting plate 700, and the pressing distance of the pressure lever 400 can be increased by changing the length of the connecting plate 700, so that the requirements of applying different pre-pressures are met.
The compression bar 400 comprises a rotary fork 410 and a stress application bar 420, the rotary fork 410 is in a shape of a Chinese character 'ji', both ends of the head of the rotary fork 410 are hinged with both sides of the sliding sleeve 600 through rotary pins, both sides of the middle of the rotary fork 410 are hinged with both sides of the compression sleeve 500 through connecting plates 700, and one end of the stress application bar 420 is connected with the middle of the tail end of the rotary fork 410.
During the pressing process of the pressing rod 400, the conductive rod 100a penetrates through the vacant position of the rotating fork 410, and the rotating fork 410 is designed to be hinged with the fixing column 200 and the pressing sleeve 500 at two sides of the rotating fork 410, so that the overall reliability of the pressing rod 400 is improved.
The forcing rod 420 and the rotating fork 410 are fixed by screwing or welding. The stress application rod 420 and the rotating fork 410 are in a threaded connection mode, stress application rods 420 with different lengths can be selected according to requirements, if the pre-pressure is high, a stress application rod 420 with a longer length can be selected, and if the pre-pressure is not high, a relatively shorter stress application rod 420 can be selected, so that a proper stress application rod 420 can be selected conveniently.
Further, a conductive rod insertion hole is axially formed in the conductive rod supporting post 300. When the conducting rod 100a is installed on the conducting rod supporting column 300, the connector 110a of the conducting rod 100a is inserted into the conducting rod insertion hole, so as to fix and position the conducting rod 100 a.
The present invention is not limited to the above-described embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope defined by the claims of the present application.
