Description

Technical Field

[0001] The utility model relates to the technical field of slurry pump end cover production, in particular to a clamping device for producing the slurry pump end cover. Background Art

[0002] A slurry pump refers to a machine that increases the energy of a solid-liquid mixture by means of centrifugal force, and converts electrical energy into kinetic energy and potential energy of the medium. The end cover of a slurry pump needs to be fixed with a clamping device during production to facilitate processing of the end cover. The traditional clamping device uses three points on the outside of the end cover to squeeze towards the middle of the end cover to clamp the end cover. However, the clamping force is too large during clamping, which can easily cause the end cover to deform towards the middle, which is not conducive to the subsequent processing of the end cover.

[0003] In order to solve the above problems, application number CN202220580840.X discloses a clamping device for the production of slurry pump end covers, in which the threaded rod is driven to rotate by an electric motor, thereby moving the threaded plate to the appropriate position for appropriate adjustment according to the different diameters of the end cover, and then one of the tooth columns is driven to move by the telescopic rod. The two tooth columns are connected by a spur gear, so that the clamping plates above the two tooth columns are close to each other under the adjustment of the telescopic rod, thereby achieving simultaneous extrusion on both the inside and outside of the end cover, avoiding traditional external extrusion and fixation, which causes deformation of the end cover. At the same time, a rubber pad is provided on one side of the clamping plate. When the end cover is extruded and fixed, the outer surface of the end cover is protected to avoid scratches on the outer surface of the end cover, thereby solving the problem that the traditional clamping device only extrudes and fixes the outside of the end cover, which easily causes deformation of the end cover.

[0004] However, the clamping device for producing the end cover of a slurry pump disclosed in the above patent still cannot quickly and intelligently stop the clamping plate from continuing to translate and clamp after clamping the end cover, and it is easy to over-clamp the end cover and cause it to deform. Utility Model Content

[0005] The purpose of the present utility model is to provide a clamping device for the production of slurry pump end covers. The clamping device for the production of slurry pump end covers disclosed by the present utility model can clamp the pump end cover from three directions at the same time. Pressure sensors are installed on the clamping surfaces of the clamping strips. Together with a movable sleeve that is slidably connected to the outside of the clamping strip and can slide up and down, it can quickly detect when the pump end cover is clamped and intelligently stop inward clamping, so that the pump end cover can be clamped but will not be damaged due to clamping too tightly, thereby solving the problems raised in the above-mentioned background technology.
