[0002] Bearings are an important component in mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Common bearing types include deep groove ball bearings, angular contact ball bearings, self-aligning roller bearings, tapered roller bearings, and cylindrical roller bearings.

[0003] When machining bearings, fixtures are needed for fixing. However, traditional fixtures can only be placed and fixed on a certain plane, mostly parallel to the worktable, and cannot be adjusted according to machining requirements, thus affecting actual machining. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a fixing device for deep groove ball bearing processing, which solves the problem that traditional fixtures can only be placed and fixed on a certain plane, mostly parallel to the worktable, and cannot be adjusted according to processing requirements, thus affecting actual processing and use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for processing deep groove ball bearings, comprising a base, fixing blocks connected to both sides of the base, connecting rods connected to both sides of the upper part of the base, a fixing platform rotatably connected to the base via the connecting rods, a fixing sleeve connected to the base, a sliding groove provided inside the base, a threaded screw rotatably connected within the sliding groove, a movable plate threadedly mounted on the threaded screw, and a rectangular strip connected to one end of the threaded screw through the fixing sleeve;

[0006] A rocker arm is slidably connected to the rectangular bar, and a spring is sleeved on the rectangular bar. Hinges are rotatably connected to both sides of the movable plate via pins. A fixed plate is connected to the fixed platform, and an adjusting screw is threadedly connected to the fixed platform. A handwheel is connected to one end of the adjusting screw, and a clamping plate is rotatably connected to the other end of the adjusting screw.

[0007] As a further embodiment of this utility model: the end of the hinge rod away from the moving plate is rotatably connected to the bottom of the fixed platform via a pin, and connecting sleeves are connected to both sides of the fixed platform, with the connecting sleeves rotatably connected to the connecting rod.

[0008] As a further embodiment of this utility model: the clamping plate is in contact with the upper part of the fixing platform, the side opposite to the fixing plate and the clamping plate is arc-shaped, and rubber pads are connected to both the fixing plate and the clamping plate.

[0009] As a further embodiment of this utility model: a limiting rod is connected inside the slide groove, there are two limiting rods in total, and the two limiting rods are distributed on both sides of the threaded screw.

[0010] As a further embodiment of this utility model: a toothed groove is provided on one side of the fixing sleeve, a toothed ring is connected to one side of the rocker handle, the toothed ring is fitted into the toothed groove, one end of the spring is connected to the top of the rectangular bar, and the other end of the spring is connected to the rocker handle.

[0011] As a further embodiment of this utility model: the movable plate has connecting holes on both sides, and the movable plate is slidably connected to the limiting rod through the connecting holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This fixing device for deep groove ball bearing machining, by setting up a crank handle, a threaded screw, a moving plate, a hinge rod, a connecting sleeve, and a connecting rod, allows the operator to drive the threaded screw to rotate in the groove via the crank handle, thereby causing the moving plate to move along the threaded screw in the groove. As the moving plate moves, the two ends of the hinge rod rotate, thus the hinge rod pushes the fixing table as the moving plate moves, causing the connecting sleeve to rotate on the connecting rod, thereby adjusting the overall angle of the fixing table to meet different machining requirements, improving the applicability of the fixing device, and making it easy to operate.

[0014] 2. The fixing device for machining deep groove ball bearings consists of an adjusting screw, handwheel, clamping plate, fixing plate, spring, gear ring, and toothed groove. When the operator pulls the crank handle to slide on the rectangular bar, the crank handle compresses the spring. After the crank handle is released, the spring's rebound force pushes the crank handle to slide on the rectangular bar, causing the gear ring to insert into the toothed groove. This combines the crank handle and the fixing sleeve to fix the threaded screw, preventing accidental rotation. Rotating the adjusting screw by the handwheel causes the adjusting screw to move the clamping plate, which, in conjunction with the fixing plate, clamps and fixes the bearing, preventing slippage and tilting during machining.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a fixing device for processing deep groove ball bearings, including a base 1, fixing blocks 2 connected to both sides of the base 1, connecting rods 3 connected to both sides of the top of the base 1, a fixing platform 4 rotatably connected to the base 1 through the connecting rods 3, a fixing sleeve 5 connected to the base 1, a toothed groove 20 provided on one side of the fixing sleeve 5, a toothed ring 21 connected to one side of the crank handle 10, the toothed ring 21 fitting into the toothed groove 20, one end of the spring 11 connected to the top of the rectangular bar 9, and the other end of the spring 11 connected to the crank handle 10. When the operator pulls the crank handle 10 to disengage the toothed ring 21 from the toothed groove 20, the crank handle 10 sliding along the rectangular bar 9 will compress the spring 11. Thus, after the crank handle 10 is released, the spring 11 rebounds and causes the toothed ring 21 to automatically embed into the toothed groove 20, thereby fixing the threaded screw 7, simplifying the operation and making it easy to use.

[0022] The base 1 has a groove 6 inside, and a threaded screw 7 is rotatably connected in the groove 6. There are two limiting rods 19 connected in the groove 6, and the two limiting rods 19 are distributed on both sides of the threaded screw 7. By rotating the threaded screw 7, the movable plate 8 that is threaded with the threaded screw 7 can move along the limiting rods 19 in the groove 6, thereby changing the angle of the hinge rod 12, causing the hinge rod 12 to push the fixed platform 4 to rotate to adjust the working angle.

[0023] A movable plate 8 is threadedly installed on the threaded screw 7. Connecting holes 22 are provided on both sides of the movable plate 8. The movable plate 8 is slidably connected to the limiting rod 19 through the connecting holes 22. When the movable plate 8 moves along the threaded screw 7, the movable plate 8 will slide along the limiting rod 19 through the connecting holes 22. Thus, the two limiting rods 19 restrict and guide the movable plate 8, preventing the movable plate 8 from tilting as the threaded screw 7 rotates.

[0024] One end of the threaded screw 7 passes through the fixed sleeve 5 and is connected to a rectangular bar 9. A rocker arm 10 is slidably connected to the rectangular bar 9, and a spring 11 is sleeved on the rectangular bar 9. The two sides of the movable plate 8 are rotatably connected to the hinge rod 12 via pins. The end of the hinge rod 12 away from the movable plate 8 is rotatably connected to the bottom of the fixed platform 4 via a pin. The two sides of the fixed platform 4 are connected to the connecting sleeve 17, which is rotatably connected to the connecting rod 3. When the hinge rod 12 pushes the fixed platform 4, the connecting sleeve 17 will rotate around the connecting rod 3, thereby changing the overall angle of the fixed platform 4, which makes it convenient for the staff to process the bearing at different angles.

[0025] A fixed plate 13 is connected to the fixed platform 4, and an adjusting screw 14 is threaded onto the fixed platform 4. One end of the adjusting screw 14 is connected to a handwheel 15, and the other end of the adjusting screw 14 is rotatably connected to a clamping plate 16. The clamping plate 16 is in contact with the top of the fixed platform 4. The opposite sides of the fixed plate 13 and the clamping plate 16 are both arc-shaped. Rubber pads 18 are connected to both the fixed plate 13 and the clamping plate 16. When the clamping plate 16 and the fixed plate 13 are in contact with the bearing, the rubber pads 18 will be squeezed, so that the rubber pads 18 can fit in close contact with the bearing, increasing friction and improving the stability of the clamping.

[0026] The working principle of this utility model is as follows:

[0027] The operator places the bearing on the fixed table 4, then rotates the adjusting screw 14 by handwheel 15, causing the adjusting screw 14 to push the clamping plate 16 to move. This allows the clamping plate 16 to cooperate with the fixed plate 13 to clamp and fix the bearing, preventing it from slipping or tilting during processing. The operator then pulls the rocker handle 10, causing it to slide along the rectangular bar 9 and compress the spring 11, causing the gear ring 21 to disengage from the toothed groove 20. The rocker handle 10 then drives the threaded screw 7 to rotate, causing the moving plate 8 to slide along the threaded screw 7 in the groove. The hinge rod 12 rotates when the moving plate 8 moves, thereby pushing the fixed platform 4 through the hinge rod 12, causing the connecting sleeve 17 to rotate on the connecting rod 3, thereby adjusting the overall angle of the fixed platform 4 to meet different processing requirements. After the rocker handle 10 is released, the spring 11 rebounds, thereby pushing the rocker handle 10 to slide on the rectangular bar 9 through the rebound force of the spring 11, causing the toothed ring 21 to be inserted into the toothed groove 20, thereby combining the rocker handle 10 and the fixed sleeve 5 together to fix the threaded screw 7.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
