It solves the problem that the existing bearing processing and fixing devices have poor fixing effects. It includes a processing table fixed on the ground, and a processing arm, a fixed seat and a drilling table are arranged on the table top of the processing table, wherein the processing arm and the drilling table are respectively located on both sides of the fixed seat, and a movable arm and a first guide rail are arranged on the processing arm, and the first guide rail is longitudinally laid on the side of the processing arm facing the fixed seat, and the movable arm is movably arranged on the first guide rail and can move up and down along the first guide rail, and a chuck is arranged on the movable arm, and the chuck is opposite to the fixed seat. When the movable arm descends, the chuck can cooperate with the fixed seat to fix the bearing to be processed; a second guide rail is arranged horizontally on the processing table, and the drilling table is arranged on the second guide rail and can move horizontally along the second guide rail, and a drill bit is arranged on the drilling table.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when used, the above equipment can solve the problem that the bearing is not stable enough during drilling and will shake, resulting in poor drilling accuracy. In addition, the existing bearing processing and fixing process takes a long time and has low processing efficiency.

A limiting arc strip 4 is provided on the right side of the top of the fixing seat 3, and both sides of the left side of the top of the chuck 2 are threadedly connected with limiting bolts 5. An adjusting mechanism 6 is provided on the right side of the top of the fixing seat 3, and the thickness of the limiting arc strip 4 is 0.2 cm.

[0023] refer to Figure 3The adjusting mechanism 6 includes a movable groove 61, which is opened on the right side of the bottom of the inner wall of the fixed seat 3. The left side of the inner wall of the movable groove 61 is movably connected with a screw 62 through an axle pin. The bottom of the limiting arc bar 4 is fixedly connected to the screw sleeve 63, and the inner wall of the screw sleeve 63 is threadedly connected to the right side of the surface of the screw 62.

[0024] As a technical optimization solution of the present invention, by setting up an adjustment mechanism 6, the user can rotate the screw 62 so that the screw 62 drives the screw sleeve 63 to move to the left, and then the screw sleeve 63 will drive the limiting arc bar 4 to move to the left, and then the limiting arc bar 4 can tighten the bearing part, thereby further improving the fixing effect of the bearing part.

[0025] refer to Figure 3 The bottom of the right side of the fixing seat 3 is fixedly connected with a limiting piece 7, two limiting pieces 7 are provided, and the material of the limiting piece 7 is carbon steel.

[0026] As a technical optimization solution of the present invention, by providing a limit plate 7, the user can use the limit plate 7 to limit the maximum movable space of the screw sleeve 63, preventing the screw sleeve 63 from moving too far to the right during movement, causing the screw sleeve 63 to be separated from the movable groove 61, thereby improving the stability of the screw sleeve 63 during use, and utilizing the advantage of the high hardness of carbon steel to increase the service life of the limit block.

[0027] refer to Figure 3 A force block 8 is provided on the right side of the screw rod 62 , and the left side of the force block 8 is welded to the right side of the screw rod 62 .

[0028] As a technical optimization solution of the present invention, by setting a force block 8, when the user needs to rotate the screw 62, the user can pinch the force block 8 to rotate it, and then the force block 8 will drive the screw 62 to rotate, giving the user a point of force for applying force, and then the force block 8 is welded to the screw 62 to avoid the force block 8 from falling.

[0029] refer to Figure 3 The surface of the force block 8 is provided with anti-skid grooves 9, and a plurality of anti-skid grooves 9 are provided and are distributed in a horizontal ring at equal distances.

[0030] As a technical optimization solution of the present invention, by providing an anti-slip groove 9, the user's hand can contact the force block 8 through the anti-slip groove 9 when rotating the force block 8, thereby greatly improving the friction between the user's hand and the force block 8, and preventing slipping caused by excessively low friction.

[0031] refer to Figure 1 The top of the limit bolt 5 is fixedly connected with a knob 10, which is arranged in a three-pointed star shape.

[0032] As a technical optimization solution of the present invention, by setting the knob 10, when the user needs to rotate the limit bolt 5, the user can drive the limit bolt 5 to rotate by rotating the knob 10, giving the user a fulcrum for applying force to the limit bolt 5.

[0034] As a technical optimization solution of the present invention, by setting a scale groove 11, the user can quickly understand the current downward movement distance of the limit bolt 5 by comparing the bottom of the limit bolt 5 with the scale groove 11 when adjusting the limit bolt 5 to rotate downward.

[0035] The working principle and use process of the present invention are as follows: after the user places the bearing to be processed on the top of the fixing seat 3, the user can use the adjusting frame 1 to drive the chuck 2 to move downward, and then the chuck 2 will clamp and fix the bearing on the positioning seat. Then the user can rotate the limit bolt 5 to make the limit bolt 5 rotate and move downward so as to limit the bearing to the left. At the same time, the user can adjust the downward movement distance of the limit bolt 5 according to the thickness of the bearing to ensure that the limit bolt 5 can prevent the bearing from drilling into the limit bolt 5 when the bearing is sufficiently limited. The positioning arc strip 4 can limit the bearing component to the right, thereby improving the limiting effect of the bearing component. The thickness of the limiting arc strip 4 is 0.2 cm, which ensures that the limiting arc strip 4 can prevent the bearing component from being drilled into the limiting arc strip 4 when drilling a hole while sufficiently limiting the bearing component. Then the user can rotate the screw rod 62 so that the screw rod 62 drives the screw sleeve 63 to move to the left, and then the screw sleeve 63 will drive the limiting arc strip 4 to move to the left, and then the limiting arc strip 4 can tighten the bearing component, thereby further improving the fixing effect of the bearing component, and having the ability to improve stability and avoid drilling damage to the limiting component.

[0036] To sum up: the fixing device for bearing processing, by setting a limit bolt 5, rotating the limit bolt 5, so that the limit bolt 5 rotates and moves downward, so that the bearing part can be limited to the left, and then the limit arc bar 4 is used to limit the bearing part to the right, thereby improving the limiting effect of the bearing part, and solving the problem of relying solely on the baffle to limit the bearing to the left, but the bearing cannot be limited to the right after being positioned and fixed, resulting in a certain instability in the bearing drilling process. At the same time, the height of the baffle cannot be adjusted. If the limiting height of the baffle is high, the drill bit of the punching machine is likely to drill into the baffle, causing damage to the baffle and inability to continue limiting.
