The invention discloses an assembling, clamping and measuring device for a PDC combined drill bit. The assembling, clamping and measuring device comprises an assembling clamp. The assembling clamp iscomposed of a locating seat, a locating ring, a support seat, an assembling ring gauge and a clamping assembly. A ringlike main body of the locating ring is internally provided with a central hole. APDC base body extends into the central hole to be located. The locating ring is located to the locating seat and clamped through the locating seat. The support seat is located onto the locating seat.The assembling ring gauge and the clamping assembly are located onto the support seat. The middle of the assembling ring gauge is provided with a locating hole, and the locating hole is coaxial with the central hole. By means of the assembling ring gauge, a toothed gear part is located to the upper end of the PDC base body. The clamping assembly comprises clamping jacking heads. The clamping jacking heads act on the outsides of toothed palms in an abutting manner so that the toothed gear part can be clamped. The assembling, clamping and measuring device further comprises a measuring assembly.The measuring assembly is composed of a measuring plate and a depth gauge. The measuring plate is arranged on the assembling ring gauge. The upper surface of a plate body is in contact with a measuring base of the depth gauge. A measuring head of the depth gauge is in contact with the high point of the PDC combined drill bit. By means of the assembling, clamping and measuring device, it can be guaranteed that assembling and welding can be completed one time; and the height difference, coaxiality and outer diameter of the toothed gear part can meet design requirements.
Description
technical field [0001] The invention relates to the field of processing and manufacturing of mine drill bits, in particular to an assembly clamping and measuring device of a PDC composite drill bit. Background technique [0002] Such as figure 1 As shown, the PDC composite drill bit is composed of a PDC matrix 1 and a cone component. The cone component part includes two palms 2, and each palm 2 is rotatably connected with a cone 3 respectively. During the production and processing of the PDC composite drill bit, the two palms 2 need to be welded on the PDC matrix 1 respectively. During welding, the concentricity and height difference required by the cone part are required to meet the design requirements, that is, the concentricity of the two palms 2 should be high, and the height difference between the two cones 3 should be close to zero. [0003] At present, the method used by various manufacturers is to first weld the palm 2 on the PDC substrate 1, and then measure it on...
