Embodiment 1

[0020] Such as figure 1 , a fixing seat for processing the oil groove of the inner ring of the bearing, including a connecting plate 3, a baffle plate 5, a nut 6, a screw rod 7 and at least two connecting bolts 1, and the connecting plate 3 is provided with the number and connecting bolts 1 The number of bolt holes is equal, the connecting bolts 1 are respectively located in one bolt hole, the screw rod 7 is fixedly connected with the connection plate 3, and the axis of the screw rod 7 and the connection plate 3 is collinear, and the baffle plate 5 and the screw rod 7 form a clearance fit , between the baffle plate 5 and the connection plate 3, a clamping groove 4 for clamping the inner ring of the bearing is formed, the nut 6 is threadedly connected with the screw rod 7, and the baffle plate 5 is located between the nut 6 and the connection plate 3, Both the adjacent sides of the connection plate 3 and the baffle plate 5 are provided with bosses 8, and the axes of the two bos...

Embodiment 2

[0024] The present embodiment is further limited on the basis of embodiment 1, as figure 1 , in order to facilitate the installation of the connecting plate 3, a pin hole is also provided on the connecting plate 3, and a positioning pin 2 is arranged in the pin hole.

[0025] In order to reduce or eliminate the vibration of the main shaft of the lathe due to the centrifugal force generated during the working process of the present invention, the connecting disc 3 is disc-shaped.

[0026] In order to avoid the impact of the connecting bolt 1 on the installation of the inner ring of the bearing, the bolt holes are concentric and different-diameter holes, the connecting bolt 1 is a hexagon socket bolt, and the nut end of the connecting bolt 1 is located between the two ends of the connecting plate 3 between.

[0027] In order to enhance the anti-loosening performance of the nut 6, the thread on the screw mandrel 7 is a fine pitch thread.

Embodiment 3

[0029] This embodiment is further limited on the basis of the above embodiments, as figure 1 , in order to facilitate the replacement of screw rods 7 of different lengths according to the number of bearing inner rings sleeved on the screw rod 7 or the width of the bearing inner ring, the connected keyboard 3 is provided with a screw hole, and the screw hole is provided with Internal thread, the screw mandrel 7 is threadedly connected with the connecting disc 3 .

Abstract

The invention discloses a fixing seat for machining a bearing inner ring oil groove. The fixing seat for machining the bearing inner ring oil groove comprises a connecting disc, a blocking plate, a nut, a lead screw and at least two connecting bolts, wherein bolt holes identical to the connecting bolts in number are formed in the connecting disc, the connecting bolts are respectively located in the bolt holes, the lead screw is fixedly connected with the connecting disc, the axes of the lead screw and the connecting disc are collinear, and the blocking plate is in clearance fit with the lead screw. A clamping groove for a bearing inner ring to be clamped is formed between the blocking plate and the connecting disc, the nut is in threaded connection with the lead screw, the blocking plate is located between the nut and the connecting disc, bosses are arranged on the adjacent sides of the connecting disc and the blocking plate, the axes of the two bosses are collinear with the axis of the lead screw, and the outer edges of the two bosses are flush. The fixing seat is used for the bearing inner ring to be clamped, and improvement of turning machining precision of the bearing inner ring is facilitated. The contact face between the bearing inner ring and the fixing seat is large, machining indentations are prevented from being produced, and improvement of the installing quality of a bearing matched with a bearing seat or a shaft finally is facilitated.

Description

technical field [0001] The invention relates to the field of a tooling device used for lathe clamping objects, in particular to a fixing seat used for processing oil grooves of inner rings of bearings. Background technique [0002] Spherical roller bearings are suitable for heavy loads and shock loads. Spherical roller bearings have two rows of symmetrically arranged spherical rollers. The rollers can be freely adjusted in the inner spherical raceway of the inner ring, so that the shaft deformation and the misalignment error of the bearing housing can be compensated. It is widely used in the power industry , food processing industry, transportation mining industry, construction industry, etc., is an indispensable mechanical part in the field of industrial production equipment and civilian life. In its manufacturing process, it is the guarantee of normal industrial production and the quality of people's life to achieve excellence in its processing links. [0003] In the pri...
