Description

TECHNICAL FIELD

[0001] The utility model relates to bearing processing technical field, especially a kind of hub bearing channel grinding tooling. BACKGROUND

[0002] The channel of current hub bearing generally needs to be ground, and the grinding principle is generally that a cylindrical ring-shaped abutment is installed on the rotating spindle of a grinding machine, the hub bearing is inserted into the abutment, the flange surface of the hub bearing abuts against the end face of the abutment, and then the hub bearing is ground by using a grinding wheel. Since the hub bearing rotates during grinding, the flange surface of the hub bearing rotates relative to the abutment. In addition, the abutment is generally made of metal, and the abutment is easily worn after a period of time. After wearing, the abutment needs to be replaced or ground again, which increases the production cost. SUMMARY

[0003] The utility model aims to provide a kind of hub bearing channel grinding tooling, by increasing ceramic sheet on abutment, by the characteristics of high hardness and wear resistance of ceramic sheet, the service life of the entire tooling can be effectively improved, and the production cost is reduced.

[0004] The above technical purpose of the utility model is realized by the following technical scheme:

[0005] A kind of hub bearing channel grinding tooling, comprising an abutment, the abutment is cylindrical;The side surface of the abutment is formed with a clearance counterbore and a plurality of clamping grooves circumferentially distributed about the clearance counterbore;The ceramic sheet is fixed in the clamping groove.

[0006] The ceramic sheet is higher than the abutment.

[0007] During grinding, the abutment is fixed on the grinding machine, and one end surface of the hub bearing abuts against the ceramic sheet. Due to the high hardness and wear resistance of the ceramic sheet, the hub bearing will not be ground on the ceramic sheet during grinding, and the wear of the ceramic sheet is small, thereby improving the service life of the entire tooling and reducing the production cost.

[0008] After the ceramic sheet is installed on the abutment, the ceramic sheet needs to be ground to ensure that the ceramic sheet is set at the same height.

[0009] The utility model is further provided with a plurality of first grooves formed on the bottom surface of the clamping groove.

[0010] The ceramic sheet is generally glued in the clamping groove by using glue. By providing the first grooves on the bottom surface of the clamping groove, the fixing stability of the ceramic sheet can be improved.

[0011] The utility model further sets up: the side face of the ceramic piece side to the clamping groove bottom surface is formed with second sunken groove, through setting up second sunken groove, can further improve the combination ability of glue and ceramic piece, to further improve the fixed stability of ceramic piece.

[0012] The utility model further sets up: the bottom surface of clamping groove is formed with through hole, when needing to replace ceramic piece, can install the ejector rod in the through hole, to top out ceramic piece, to convenient ceramic piece's dismounting work.

[0013] The utility model further sets up: the through hole is threaded through hole, and the screw is screwed in the through hole, and ceramic piece can be slowly top out by rotating the screw, and ceramic piece can be further conveniently dismounted.

[0014] The utility model further sets up: the bottom surface of the yielding hole is formed with a plurality of mounting holes, and the abutment is fixed on the grinding machine by sleeving the screw in the mounting hole.

[0015] The other side of the abutment is formed with a weight-reducing sunken groove, which can greatly reduce the weight of the abutment, thereby facilitating and easily installing and dismounting the abutment.

[0016] The utility model further sets up: the edge chamfer or round corner treatment of ceramic piece can reduce damage and bruise in the grinding process of bearing.

[0017] The utility model has the following advantages:

[0018] Compared with the prior art, by increasing ceramic piece on the abutment, by the characteristics of high hardness and wear resistance of ceramic piece, the service life of the whole tooling can be effectively improved, and the production cost can be reduced.

[0019] Meanwhile, the existing hub bearing and ceramic piece are in contact with the piece, which can further reduce the wear of the hub bearing itself compared with the previous contact with the whole surface of the abutment.

[0020] When the ceramic piece is worn, only the ceramic piece needs to be replaced or ground, and the abutment can still be used, which can effectively reduce the production cost.

[0021] By setting the sunken groove on the clamping groove and the ceramic piece, the installation stability of the ceramic piece can be improved.

[0022] By setting the through hole on the clamping groove, the dismounting and replacement work of the ceramic piece can be facilitated. DRAWINGS

[0030] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0031] The following is for reference Figures 1 to 4 The embodiments of this utility model are described below:

[0032] A tooling for grinding wheel hub bearing grooves, such as Figure 1 As shown, it includes a support 1, which is cylindrical; a recessed hole 101 and a plurality of slots 102 evenly distributed around the circumference of the recessed hole 101 are formed on one side of the support 1; a ceramic piece 2 is fixed in the slot 102.

[0033] The ceramic plate 2 is positioned above the support 1.

[0034] During grinding, the support is fixed on the grinding machine, and one end face of the wheel hub bearing is attached to the ceramic plate. Due to the wear resistance and high hardness of the ceramic plate, the wheel hub bearing will not generate grinding on the ceramic plate during grinding. The wear of the ceramic plate is small, which can improve the service life of the entire tooling and reduce production costs.

[0035] After the ceramic plate is installed on the base, it needs to be ground to ensure that the ceramic plate is set at the same height.

[0036] like Figure 3 , Figure 4 As shown, a plurality of first recessed grooves 103 are formed on the bottom surface of the card slot 102 in this embodiment.

[0037] The ceramic sheet is usually glued to the slot with adhesive 3. By setting a first recess on the bottom of the slot, the fixing stability of the ceramic sheet can be improved.

[0038] A second recess 201 is formed on the side of the ceramic sheet 2 facing the bottom surface of the slot 102. By setting the second recess, the bonding ability between the adhesive and the ceramic sheet can be further improved, thereby further improving the fixing stability of the ceramic sheet.

[0039] The bottom surface of the slot 102 is formed with a through hole 104. When it is necessary to replace the ceramic sheet, a push rod can be installed in the through hole to push the ceramic sheet out, thereby facilitating the disassembly of the ceramic sheet.

[0040] The through hole 104 is a threaded through hole, and a screw is screwed into the through hole. By rotating the screw, the ceramic sheet can be slowly pushed out, which can further facilitate the disassembly of the ceramic sheet.

[0041] like Figure 2 , Figure 3 As shown, the bottom surface of the countersunk hole 101 in this embodiment is formed with a plurality of mounting holes 105, and the support is fixed on the grinding machine by the screws in the mounting holes.

[0042] The other side of the backrest 1 is formed with a weight-reducing groove 106, which can significantly reduce the weight of the backrest, thereby making it convenient and easy to install and remove the backrest.

[0043] The chamfering or rounding of the edges of the ceramic sheet 2 can reduce damage and impact damage to the bearing during the grinding process.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
