Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to specific embodiments:

[0020] like Figure 3 As shown, a clamping device for positioning a bearing housing 8 includes a base plate 1 and multiple sets of front mounting mechanisms and multiple sets of back mounting mechanisms fixedly mounted on the base plate 1. The front mounting mechanism includes a support leveling block 2, a lateral positioning seat 3, a lateral fastening seat 4, a guide assembly, and a locking assembly. The two ends and two sides of one end of the bearing housing 8 facing upward are in contact with the support leveling block 2, and the two sides of the other end are in contact with the lateral positioning seat 3 and the lateral fastening seat 4, respectively. The guide assembly is provided corresponding to the bearing hole 84 of the bearing housing 8. The locking assembly is provided to press the bearing housing 8 tightly. The back mounting mechanism includes a positioning support frame 7. The bearing housing 8 facing upward is fixed on the positioning support frame 7 by a positioning pin 71 and an internal hexagon lock screw 72.

[0021] The front and back mounting mechanisms are arranged side by side and correspond one to one, with equal spacing between them.

[0022] Support screws are mounted on the support leveling block 2. The support leveling block 2 has threaded holes that match the support screws. The support screws are adjusted in height by threading into the threaded holes so that the top of the support screw contacts the lower surface of the bearing housing 8. The support leveling block 2 is used to increase the height of the support screws, thereby expanding the screw adjustment space and facilitating operation. The support leveling block 2 has two locking countersunk holes to fix the support leveling block 2 to the base plate 1. Figure 1 As shown, the bottom surface of the bearing housing 8 has three positioning support points 82 and one clamping support point 83. In each set of front mounting mechanisms, the support screws are divided into three positioning support screws 21 and one clamping support screw 22. The three positioning support screws 21 abut against the three positioning support points 82 respectively. The positioning support screws 21 are external hexagonal screws, normally in a fixed state at the same height, and can be adjusted to facilitate the adjustment of the support point height when the blank is abnormal. The clamping support screw 22, after adjusting its height, achieves effective contact with the clamping support point 83, and is pressed down with a pressure plate to lock the bearing housing 8.

[0023] The lateral positioning seat 3 is constructed by welding two square steel pieces together to form an L-shape, saving material. The lower part has two locking countersunk holes for fixing it to the base plate 1. The upper part has an inclined surface parallel to the side of the bearing housing 8, and a positioning screw perpendicular to the side of the bearing housing 8 is installed on the upper part. The positioning screw abuts against the side positioning point 81 of the bearing housing 8 for fixation. The lateral fastening seat 4 has the same shape and structure as the lateral positioning seat 3, and is positioned directly opposite the lateral positioning seat 3. Adjusting the positioning screw to abut against the side positioning point 81 of the bearing housing 8 prevents the bearing housing 8 from shifting during processing.

[0024] The guiding assembly comprises a positioning guiding shaft 51 fixed on the base plate 1, a tapered positioning pin 52 and a compression spring 53 sleeved on the positioning guiding shaft 51, and the tapered positioning pin 52 is fixed at the top end of the compression spring 53 and used for positioning the bearing hole 84 on the bearing seat 8. The bearing hole 84 is in a rough state, and the hole diameter may be different, so the tapered positioning pin 52 is arranged in a tapered form to achieve effective abutment and positioning. The top end of the positioning guiding shaft 51 is provided with a check ring to limit the upward movement position of the tapered positioning pin 52 and prevent it from falling off.

[0025] As shown in Figure 4 , the locking assembly comprises a locking pressing plate 61, a locking screw 62 and a support rod 63, the bottom end of the locking screw 62 is fixed on the base plate 1, the locking pressing plate 61 is sleeved on the locking screw 62, the support rod 63 is vertically arranged and the bottom end is in contact with the base plate 1, the locking screw 62 is provided with a nut, the inner ring of the nut is provided with a thread matched with the locking screw 62, the locking pressing plate 61 is adjusted to be tightly pressed on the protruding part at the end of the bearing seat 8 through the nut, and the support rod 63 is supported on the end of the locking pressing plate 61 away from the protruding part of the bearing seat 8. The locking screw 62 and the nut are used for locking the locking pressing plate 61 and the protruding part at the end of the bearing seat 8, and for the locking assembly located at the edge, the support rod 63 can support one end of the locking pressing plate 61, and the other end of the locking pressing plate 61 is pressed on the protruding part and supported by the protruding part. The locking assembly between the two adjacent front mounting mechanisms only adopts the locking screw 62, the locking pressing plate 61 and the nut, and the two ends of the locking pressing plate 61 are respectively pressed on the protruding parts of the two adjacent bearing seats 8 close to each other.

[0026] The bottom of the positioning support frame 7 is a fixed plate fixed on the base plate 1, the middle part is two support heightening blocks and a reinforcing rib plate, and the upper part is two positioning plates provided with locking holes and fixing pin holes and connected by welding. Figure 2 and Figure 4 As shown in the drawings, the positioning pin 71 is inserted into the positioning hole 85 on the front surface of the bearing seat 8 and the fixing pin hole on the positioning plate at two ends, respectively, the internal hexagonal locking screw 72 is screwed with the screw hole 86 on the front surface of the bearing seat 8 through the locking hole on the positioning plate to lock the bearing seat 8.
