Description

Floating support device

[0001] The invention belongs to the field of water pump production, and particularly relates to a floating support device on a sludge pump outlet pipe processing device.

Background technique

[0002] The sludge pump is one of many pumps. It is one of the special pumps for turbid water with a large amount of sediment. In order to adapt to various pumping environments, the outlet pipe of the sludge pump is often designed. To form an irregular non-linear pipe, in order to ensure the connection between the outlet pipe and the pump casing, it is necessary to provide a flange at the end of the outlet pipe, and a hole for connecting the outlet pipe and the water pump casing on the flange, due to these The hole needs to correspond to the hole on the water pump housing. Therefore, the machining accuracy requires the positional accuracy of the hole and the verticality of the hole and the flange end face to meet the design requirements. Otherwise, the flange is generated when the water outlet pipe is connected to the water pump housing. It is not tightly coupled with the water pump housing, or the locking bolt interferes with the hole in the flange, so that the pressing force of the locking bolt cannot be applied between the flange and the water pump housing, resulting in a weak connection; The processing precision of the hole on the flange of the outlet pipe end needs to be strictly guaranteed; because the shape of the outlet pipe of the sewage pump is irregular, the processing method of the hole on the flange is mostly drilled by drilling machine, drilling In the process, the following problems will be encountered. Firstly, if drilling is performed from the outer end of the flange, the rear end cannot be supported, resulting in unstable drilling, and the accuracy of drilling is not guaranteed. If drilling from the inner end, due to the flange distance The distance between the external walls is relatively close, and the drilling fixture on the drilling machine will interfere with the outer wall of the tube. Therefore, the drill bit needs to be lengthened. However, the lengthening of the drill bit will cause the drill rod to deform, which will cause deformation of the drill hole and seriously affect the drilling. Hole accuracy.
