[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] like Figure 2 As shown, a processing tool 10 for a shaft part 20 proposed in an embodiment of the utility model includes: a base 101, a bearing block 102, a stopper 103, a column 104, a pressure strip 105, a fixing bolt 106, and a side stopper bolt 107;

[0022] The bearing blocks 102 are configured in two and fixed on the base 101 at a distance; the two bearing blocks 102 are provided with corresponding concave bearing parts 1021 for bearing the two ends of the shaft body 201 of the shaft part 20;

[0023] The stopper 103 is installed between the two bearing blocks 102; the stopper 103 is L-shaped, including a horizontal bottom and a vertical portion, the horizontal bottom of the stopper 103 is fixed on the base 101, and the vertical portion of the stopper 103 is used for the side stopper bolt 107 to abut against;

[0024] The column 104 is fixed on the base 101 and is located on one side of the stopper 103;

[0025] The fixing bolt 106 is vertically fixed on the base 101 and is located between the stopper 103 and the column 104;

[0026] The pressure strip 105 is provided with a through hole so that the pressure strip 105 can be sleeved on the fixing bolt 106; one end of the pressure strip 105 can extend above the stopper 103, and the other end can extend above the column 104;

[0027] The side stop bolt 107 is matched with the threaded hole 203 on the disk body 202 of the shaft part 20.

[0028] When clamping the shaft part 20 in the background technology, first screw the side stop bolt 107 into the threaded hole 203 at the bottom of the disk body 202; place the two ends of the shaft body 201 on the concave bearing parts 1021 of the two bearing blocks 102 respectively, and the concave bearing parts 1021 can prevent the shaft part 10 from rotating to a certain extent; slightly rotate the shaft body 201, and make the side stop bolt 107 connected to the disk body 202 lean against the vertical part of the block 103; then put the pressure strip 105 on the fixing bolt 106, and make the pressure strip 105 When it descends, one end of the pressure strip 105 is pressed on the disk 202 of the shaft part 20, and the other end is supported on the column 104; the column 104 can keep the pressure strip 105 in a balanced state; the pressure strip 105 only needs to provide an appropriate force through the nut to press the shaft part 20, and due to the cooperation of the concave bearing parts 1021 of the two bearing blocks 102 and the stop block 103 and the side stop bolt 107, the shaft part 20 is not easy to rotate; the processing accuracy of the keyway 204 in the vertical direction of the lowest threaded hole 203 can be guaranteed.

[0029] Preferably, an adjustment threaded hole is provided at the top of the column 104, and an adjustment bolt is provided in the adjustment threaded hole; the adjustment bolt can be adjusted at the top of the column 104 to adapt to shaft parts 10 of different specifications. The diameters of the disk body 202 of shaft parts 10 of different specifications may be different. The adjustment bolt can ensure that the pressure strip 105 can maintain a balanced state when it is pressed on the disk body 202 of different diameters.

[0030] In this embodiment, the concave bearing portion 1021 of the bearing block 102 is a V-shaped groove; in other embodiments, the concave bearing portion 1021 of the bearing block 102 may also be an arc-shaped groove or the like.

[0031] More preferably, an arc-shaped transition portion is provided between the horizontal bottom and the vertical portion of the stopper 103 ; the arc-shaped transition portion between the horizontal bottom and the vertical portion of the stopper 103 can better abut against the side stopper bolt 107 .

[0032] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
