In a traditional belt feeder, a combination of a carrier roller bearing seat 100 and a deep groove ball bearing is respectively installed at two ends of a carrier roller, the deep groove ball bearing is installed in a space between a front clamping groove 1013 and a rear clamping groove 1014 in a sleeve inner cylindrical surface 1015, and an elastic retainer ring for a hole is respectively installed in the front clamping groove 1013 and the rear clamping groove 1014 to prevent the deep groove ball bearing from moving along the axial direction. The deep groove ball bearing has a high requirement on the coaxiality tolerance of the inner cylindrical surfaces 1015 of the two sleeves, otherwise the service life of the deep groove ball bearing is obviously shortened. Whether the lower surfaces of the base plates 104 of the two idler roller bearing blocks 100 are exactly in the same plane during installation directly determines the coaxiality of the inner cylindrical surfaces 1015 of the two sleeves, so that the distance tolerance between the base plates 104 and the inner cylindrical surfaces 1015 of the sleeves is strict.
In the technical requirements of the idler bearing block 100, the axial lead of the inner cylindrical surface 1015 of the sleeve is taken as a reference, strict requirements are provided for the parallelism tolerance and the distance dimensional tolerance of the lower bottom surface of the bottom plate 104, requirements for the position tolerance of the left hole 1041 and the right hole 1042 of the bottom plate are also provided, and requirements for the position tolerance of the distance between the front clamping groove 1013 and the rear clamping groove 1014 and the position tolerance of the left hole 1041 and the right hole 1042 of the bottom plate relative to the front clamping groove 1013 are also provided. To meet these technical tolerance requirements, the programmed process is such that: 1) the manual assembly is used for spot welding, the manual assembly is used for measuring the size and marking lines on all the workpieces, the marking lines at adjacent positions are made, then the workpieces are welded together in a spot welding mode, and all the workpieces are connected into a whole. 2) And (5) manual full welding. 3) And processing the lower surface of the bottom plate 104, the front end surface 1011 of the sleeve, the left hole 1041 of the bottom plate and the right hole 1042 of the bottom plate on a boring machine or a milling machine by taking the rough surface of the inner cylindrical surface 1015 of the sleeve before processing as a clamping rough reference. 4) On a boring machine, a bottom plate left hole 1041 and a bottom plate right hole 1042 are fixed by bolts by taking the lower surface of the bottom plate 104 as a positioning reference, and a sleeve rear end surface 1012, a sleeve inner cylindrical surface 1015, a front clamping groove 1013 and a rear clamping groove 1014 are machined. The precision requirement of the carrier roller is too high, so that the processing efficiency is lower and the production cost is higher. Later, the deep groove ball bearing is changed into a self-aligning ball bearing, so that the requirement on the coaxiality tolerance of the two sleeve inner cylindrical surfaces 1015 is reduced, and the requirement on the position dimensional accuracy between the axial line of the sleeve inner cylindrical surfaces 1015 and the lower surface of the bottom plate 104 is also reduced, but the requirement cannot be lower than that of GB/T1804-M. The traditional process is excessively dependent on a boring machine, the machining efficiency is low, the requirement on precision is high, many simple and repeated works are repeated manually, and if a machine is used for replacing the manual work, the labor intensity can be greatly reduced, and the productivity is improved. Now after the technology is changed, the sleeve 101 can be subjected to finish machining on a lathe before assembly welding, including turning of a front sleeve end surface 1011, a rear sleeve end surface 1012, an inner sleeve cylindrical surface 1015, a front clamping groove 1013 and a rear clamping groove 1014, then the lower bottom surface of the bottom plate 104 is machined on the planer, drilling is performed on a drilling machine, and finally precise assembly and spot welding are performed, so that a device for precise assembly and spot welding of the carrier roller bearing seat 100 with high efficiency and high precision is urgently needed.
