Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a positioning fixture for bearing production. Background Technology

[0002] The main function of bearings is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Positioning fixtures are required during the manufacturing process of bearings.

[0003] A bearing processing positioning device is disclosed in the utility model patent with authorization announcement number CN214323171U. When a bearing outer ring is inserted between the arc-shaped notches on multiple extrusion blocks, the extrusion blocks compress the positioning spring to adapt to the size of the outer ring. After positioning is completed, the fastener is rotated to make the fastener abut against the sliding sleeve, thereby realizing the positioning and fixing of multiple sliding rods. This allows the extrusion blocks to complete the size adjustment of the bearing outer ring, making it convenient for workers to quickly insert and position the bearing outer ring.

[0004] In use, it can only fix the outer surface of the bearing. When it is necessary to fix the inner surface of the bearing, the positioning fixture needs to be replaced, which has poor adaptability. At the same time, some drilling and grinding operations require the bearing to rotate in order to meet the processing requirements of different positions on the bearing surface. The existing positioning fixture cannot rotate after the bearing is positioned and fixed. If it is necessary to process other positions on the bearing surface, the bearing needs to be removed, the processing position adjusted, and then fixed again, which is troublesome, time-consuming and labor-intensive. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a positioning fixture for bearing production. It can fix the inner and outer rings of the bearing, has good adaptability, and avoids the trouble of disassembling the bearing to adjust its processing position. It saves time and effort, thereby improving the efficiency of bearing processing and effectively solving the problems in the background art.

[0006] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0007] A positioning fixture for bearing production includes a frame. A worktable is rotatably connected to the top of the frame via a first bearing. Several positioning blocks with an arc-shaped structure are connected to the worktable via a guide mechanism. A rotation drive mechanism for driving the worktable to rotate is installed on the inner bottom of the frame. A guide drive mechanism is installed on the inner bottom of the frame at a position corresponding to the guide mechanism. A PLC controller is installed on the side of the frame and is electrically connected to an external power supply.

[0008] Furthermore, the rotation drive mechanism includes a transmission shaft, a coupling, and a servo motor. The servo motor is installed on the inner bottom of the frame. The output shaft of the servo motor is fixedly connected to the transmission shaft through the coupling. The top of the transmission shaft is fixedly connected to the bottom of the worktable. The servo motor is electrically connected to a PLC controller.

[0009] Furthermore, the guide drive mechanism includes an electric push rod and a lifting seat. The electric push rod is installed on the inner bottom of the frame, and the lifting seat is fixed to the telescopic end of the electric push rod. The electric push rod is electrically connected to the PLC controller.

[0010] Furthermore, the guide drive mechanism also includes a second bearing and a transmission frame, the transmission frame being rotatably connected to the lifting seat via the second bearing.

[0011] Furthermore, the guide drive mechanism also includes a first hinge, a connecting rod, and a second hinge. One end of the connecting rod is hinged to the top of the transmission frame via the first hinge, and the second hinge is mounted on the other end of the connecting rod.

[0012] Furthermore, the guiding mechanism includes a slider and a guide groove. The guide groove is evenly opened on the worktable. The slider is slidably connected to the inner side of the guide groove. The bottom of the slider is hinged to the end of the connecting rod through a second hinge. The positioning block is fixed to the top of the slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This positioning fixture for bearing production has the following advantages:

[0014] 1. The guide mechanism drives the guide mechanism, which in turn moves the positioning blocks, causing them to move closer or further apart. This allows the inner and outer rings of the bearing to be fixed, providing good adaptability. It can also work with the rotation drive mechanism to adjust the machining position of the bearing while simultaneously positioning it.

[0015] 2. The rotating drive mechanism drives the worktable to rotate, which in turn drives the bearing to rotate relative to the positioning block. This avoids the trouble of disassembling the bearing to adjust its processing position, saving time and effort, and thus improving the efficiency of bearing processing. Attached Figure Description

Detailed Implementation

[0020] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0021] Please see Figure 1-3 This embodiment provides a technical solution: a positioning fixture for bearing production, including a frame 1. The top of the frame 1 is rotatably connected to a worktable 6 via a first bearing 8. Several positioning blocks 7 are connected to the worktable 6 via a guide mechanism 3, and the positioning blocks 7 have an arc-shaped structure. A rotation drive mechanism 4 for driving the worktable 6 to rotate is installed on the inner bottom of the frame 1. A guide drive mechanism 5 is installed on the inner bottom of the frame 1 at the position corresponding to the guide mechanism 3. A PLC controller 2 is installed on the side of the frame 1, and the PLC controller 2 is electrically connected to an external power supply.

[0022] The rotation drive mechanism 4 includes a drive shaft 41, a coupling 42, and a servo motor 43. The servo motor 43 is installed on the inner bottom of the frame 1. The output shaft of the servo motor 43 is fixedly connected to the drive shaft 41 through the coupling 42. The top of the drive shaft 41 is fixedly connected to the bottom of the worktable 6. The servo motor 43 is electrically connected to the PLC controller 2. When the bearing needs to rotate, the output shaft of the servo motor 43 drives the drive shaft 41 to rotate through the coupling 42. The drive shaft 41 drives the worktable 6 to rotate, thereby driving the bearing to rotate relative to the positioning block 7. This avoids the trouble of disassembling the bearing to adjust its processing position, saving time and effort, and thus improving the efficiency of bearing processing.

[0023] The guide drive mechanism 5 includes an electric push rod 51 and a lifting seat 52. The electric push rod 51 is installed on the inner bottom of the frame 1, and the lifting seat 52 is fixed to the telescopic end of the electric push rod 51. The electric push rod 51 is electrically connected to the PLC controller 2. The guide drive mechanism 5 also includes a second bearing 53 and a transmission frame 54. The transmission frame 54 is rotatably connected to the lifting seat 52 through the second bearing 53. The guide drive mechanism 5 also includes a first hinge 55, a connecting rod 56, and a second hinge 57. One end of the connecting rod 56 is hinged to the top of the transmission frame 54 through the first hinge 55, and the second hinge 57 is installed on the other end of the connecting rod 56. The guide mechanism 3 includes a slider 31 and a guide groove 32. The guide groove 32 is evenly opened on the worktable 6. The slider 31 is slidably connected to the inner side of the guide groove 32. The bottom of the slider 31 is hinged to the end of the connecting rod 56 through the second hinge 57. The positioning block 7 is fixed. The positioning blocks 7 are fixed at the top of the slider 31. When the arc-shaped positioning blocks 7 are close together, they fix the outer circular surface of the bearing. When the arc-shaped positioning blocks 7 are far apart, they fix the inner circular surface of the bearing. The telescopic end of the electric push rod 51 drives the transmission frame 54 to move up and down through the lifting seat 52. The transmission frame 54 drives the slider 31 to slide along the guide groove 32 through the connecting rod 56. The slider 31 drives the positioning blocks 7 to move, so that the positioning blocks 7 move closer or further apart from each other. When the connecting rod 56 is in transmission, one end of the connecting rod 56 rotates relative to the slider 31 through the second hinge 57, and the other end of the connecting rod 56 rotates relative to the transmission frame 54 through the first hinge 55. It can fix the inner and outer rings of the bearing. It has good adaptability. It can cooperate with the rotation drive mechanism 4 to not only meet the positioning of the bearing, but also allow the machining position to be adjusted.

[0024] The working principle of the positioning fixture for bearing production provided by this utility model is as follows: When the arc-shaped positioning blocks 7 are brought together, the outer circular surface of the bearing is fixed; when the arc-shaped positioning blocks 7 are moved away from each other, the inner circular surface of the bearing is fixed. The telescopic end of the electric push rod 51 drives the transmission frame 54 to move up and down through the lifting seat 52. The transmission frame 54 drives the slider 31 to slide along the guide groove 32 through the connecting rod 56. The slider 31 drives the positioning blocks 7 to move, thereby making the positioning blocks 7 move closer or further apart. The connecting rod 56 moves... During transmission, one end of the connecting rod 56 rotates relative to the slider 31 via the second hinge 57, and the other end of the connecting rod 56 rotates relative to the transmission frame 54 via the first hinge 55. When the bearing needs to rotate, the output shaft of the servo motor 43 drives the transmission shaft 41 to rotate via the coupling 42. The transmission shaft 41 drives the worktable 6 to rotate, thereby driving the bearing to rotate relative to the positioning block 7. The worktable 6 rotates relative to the frame 1 via the first bearing 8, and the transmission frame 54 rotates relative to the lifting seat 52 via the second bearing 53.
