Description

Technical Field

[0001] The utility model relates to the technical field of plunger production, in particular to a lifting and positioning device for plunger production. Background Art

[0002] The plunger is different from the piston. The main difference between the plunger and the piston is the sealing. The plunger relies on the processing accuracy to make the gap between the plunger and the cylinder very small, so as to achieve the sealing effect. The gap between the piston and the cylinder is larger, and the piston ring on the piston is in close contact with the cylinder to achieve sealing. Due to the different sealing methods, the shapes are also different. In order to have a good sealing performance, the plunger is often lengthened, while the piston is shorter. Similarly, due to the high processing accuracy requirements of the plunger, the manufacturing cost is also high.

[0003] In a large plunger cylinder, the plunger has a large volume and mass. The operator usually places the plunger flat on the workstation and cleans and applies industrial lubricant to the outer wall of the plunger by rolling the plunger. The plunger is placed flat on the workstation. Due to the heavy mass of the plunger itself, metal debris or impurities at the bottom of the plunger will leave marks on the surface of the plunger. The plunger needs to be rolled when cleaning the surface and applying oil. During rolling, it is impossible to ensure that the surface of the plunger is evenly coated with oil because the outer wall will contact the workstation table. Utility Model Content

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0006] A lifting and positioning device for plunger production comprises a bracket, a mobile frame and a steering assembly installed on the top of the bracket, the steering assembly comprises a steering sleeve, the steering sleeve is movably installed on the top of the bracket, the steering sleeve comprises a support plate and an opening and closing plate, the outer wall of one side edge of the opening and closing plate is rotatably connected to the edge of one side of the support plate, the outer wall of the support plate is fixedly mounted with a steering block, the steering block is rotatably mounted on the top of the bracket, a fixing rod is fixedly mounted on the top of the mobile frame, a plurality of hooks are sleeved on the outer wall of the fixing rod, and a steering wheel is installed at the bottom of the mobile frame.

[0007] Preferably, a hole is formed at one end of the support plate away from the bracket, and a motor 1 is fixedly mounted on the outer wall of one end of the support plate hole. The opening and closing plate and the support plate are both semicircular curved plates, and the edges of the opening and closing plate and the support plate fit together to form a steering sleeve.
