[0016] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "set / provided with" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0017] like Figure 1 As shown, the milling machine structure for processing the bearing box foot surface includes a milling machine body 1, and the workbench 11 of the milling machine body 1 is installed with a clamping tool, the clamping tool includes a transverse bracket and a longitudinal limiter for inverted placement of the bearing box a, wherein the transverse bracket includes symmetrically arranged blocks 21, and the block 21 is provided with a lifting boss 22 on the inner side relative to the inner side for engaging the bearing box foot b; the longitudinal limit includes baffles 31 located on both axial sides of the bearing box a, and a detachable pressure plate 32 is arranged between the baffles 31, and the pressure plate 32 passes through the bearing box shaft hole c and presses the lower part of the inner wall of the shaft hole c.
[0018] Its working principle is as follows: the bearing box a is placed upside down on the workbench 11 of the milling machine. Since the horizontal bracket of the clamping tool is composed of symmetrically arranged stoppers 21, the lifting boss 22 on the inner side of the stopper 21 engages with the foot b of the bearing box. The two longitudinal limit stops 21 are respectively placed on both sides of the axial direction of the bearing box a to position it. A detachable pressing plate 32 is arranged between the baffles 31, and the pressing plate 32 passes through the shaft hole c of the bearing box.
[0019] And press the lower part of the inner wall of the shaft hole c to prevent the vertical position of the bearing box a from fluctuating, that is, the clamping tool realizes the three-dimensional positioning effect of horizontal clamping, longitudinal limiting and vertical fixing.
[0020] It should be noted that the above-mentioned “longitudinal” refers to the axial direction of the bearing box a, and “lateral” refers to the extending direction of the foot b, that is, the direction perpendicular to the axial direction of the bearing box a.
[0021] In the milling machine structure for machining the bearing box foot surface,
[0022] In one embodiment, the lifting boss 22 is configured as a slide bar detachably connected to the stopper 21, and one or more longitudinal slide grooves 41 are provided on the inner side of the stopper 21, that is, they are consistent with the axial direction of the bearing box. The inner side of the slide bar is connected to the longitudinal slide groove 41 through a slider 42. The slide bar is positioned on different longitudinal slide grooves to adjust its lifting height to adapt to bearing boxes a of different sizes. By replacing different slide bars, the size of the lifting boss 22 can be adjusted to adapt to the specifications of the bearing box foot b.
[0023] ——Preferably, both ends of the pressing plate 32 are connected to the baffle plate 31 by bolts 33, and a plurality of through holes are respectively arranged at both ends of the pressing plate 32, and the through holes correspond to the threaded holes arranged on the upper part of the baffle plate 31, and the bolts 33 penetrate through the through holes and are tightened with the threaded holes, that is, by rotating the bolts 33, the relative position of the pressing plate 32 and the baffle plate 31 is adjusted, so that the pressing plate 32 can press the shaft hole of the bearing box downward, and the lower surface of the pressing plate 32 is a cylindrical surface and is consistent with the inner wall of the shaft hole c of the bearing box, and the cylindrical surface fits the inner wall of the shaft hole c more closely, so as to prevent the bearing box housing from being damaged by downward pressure;
[0024] ——Furthermore, the two blocks 21 constituting the above-mentioned transverse bracket are a fixed block and a sliding block 20. The sliding block 20 is placed in the transverse track 51 and its outer side is connected to the piston rod of the power cylinder 5. The sliding block 20 is driven by the power cylinder 5 to move along the transverse track 51, thereby adjusting the distance between it and the fixed block, so that the transverse bracket can meet the requirements of bearing boxes a of different sizes;
[0025] ——Similarly, at least one of the two baffles 31 constituting the above-mentioned longitudinal limit is a movable baffle, which is connected to the worktable 11 of the milling machine body 1 through a positioning pin 6 or a bolt. The longitudinal spacing between the movable baffle 31 and the fixed baffle 31 is achieved by placing the movable baffle 31 at different positions on the worktable 11, which can effectively adapt to the limit of bearing boxes a of different sizes.

Therefore, any other modifications or equivalent replacements of configuration dimensions and internal structures made to the technical solution of the utility model, as long as they do not depart from the spirit and scope of the technical solution of the utility model, should be included in the scope of the claims of the utility model.
