[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 、 Figure 3 and Figure 4The utility model provides an embodiment: a new type of bearing boring machine, including a casing 1, which is the main structure of the boring machine, a groove is provided near the rear side of the baffle 61, and a boring tool 2 is provided on the right inner wall of the casing 1 for boring the bearing. This technology is existing technology, so it is not described in detail. A fixing frame 7 is fixedly connected to the inner wall of the upper side of the casing 1 for supporting the hydraulic rod 3. The inner wall of the fixing frame 7 is fixedly connected to the hydraulic rod 3, and its output shaft can perform telescopic movement. Through the telescopic action, the hydraulic rod 3 can drive The lifting plate 4 moves in the up and down directions, and the bottom end of the output shaft of the hydraulic rod 3 is fixedly connected to the lifting plate 4 to provide installation space for the adjustment component. A connecting mechanism is provided on the inner wall of the casing 1, and the connecting mechanism includes a fixed component and an adjustment component. The fixed component includes a slide 51, which provides a sliding support plane for the support 5, limits the sliding trajectory of the support 5, and enables the support 5 to move smoothly back and forth on the slide 51, ensuring that the bearing placed on the support 5 can be accurately aligned with the boring tool 2, which is convenient for subsequent boring processing.

[0033] Furthermore, the slide 51 is fixedly connected to the right inner wall of the casing 1, and a support 5 is slidably connected to the upper side of the slide 51 for placing the bearings to be processed. By replacing the supports 5 of different specifications, bearings of different specifications can be processed. The support 5 and the slide 51 fit tightly together, and an electric telescopic rod 52 is fixedly connected to the front inner wall of the slide 51. When its output shaft is extended or retracted, it can push or pull the fixed plate 53, thereby driving the hinged plate 54 and the block 55 connected thereto to move. It is the power source for controlling the movement of the block 55 in the slide 51 and fixing or loosening the support 5. This technology is existing technology, so it will not be described in detail.

[0034] Furthermore, a fixed plate 53 is fixedly connected to the rear side of the output shaft of the electric telescopic rod 52. As an intermediate connecting component, on the one hand, it is fixedly connected to the output shaft of the electric telescopic rod 52 to receive the power transmitted by the electric telescopic rod 52. On the other hand, it is rotatably connected to the hinged plate 54, which can convert its own linear motion into the rotational motion of the hinged plate 54, thereby driving the card block 55 to perform displacement. The left and right sides of the fixed plate 53 are rotatably connected with the hinged plates 54, which play the role of transmitting motion and changing the direction of force. When the fixed plate 53 moves under the action of the electric telescopic rod 52, the hinged plate 54 will rotate accordingly, driving the card block 55 to slide on the inner wall of the slide 51, so that the card block 55 is inserted or removed The card slot 56 away from the support platform 5 realizes the fixing or loosening operation of the support platform 5, which is convenient for replacing the support platform 5. The hinged plate 54 is rotatably connected to the side away from the fixed plate 53 with a card block 55, which can firmly fix the support platform 5 on the slide 51, ensuring that the support platform 5 will not be displaced during the bearing processing process, ensuring the stability of the bearing position, and facilitating the boring tool 2 to perform precise boring processing. The card block 55 is slidably connected to the inner wall of the slide 51, and a card slot 56 is provided on the inner wall of the middle part of the support platform 5. The card block 55 is inserted into the inner wall of the card slot 56 and used in conjunction with the card block 55. When the card block 55 is inserted into the card slot 56, the movement of the support platform 5 can be restricted, providing a stable placement and processing platform for the bearing.

[0035] Reference Figure 1 - Figure 3 The adjusting assembly includes a clamping plate 41, which is provided with two groups. When the bidirectional screw 42 rotates, it can slide horizontally in the opposite direction on the lower side of the lifting plate 4. Its main function is to clamp the two sides of the bearing placed on the support platform 5 from above, fix the position of the bearing, and prevent the bearing from shaking and other unstable conditions during the boring process to ensure the processing accuracy. The clamping plate 41 is slidably connected to the inner wall of the lower side of the lifting plate 4. The inner wall of the lifting plate 4 is rotatably connected to the bidirectional screw 42, which is driven to rotate by the driving motor 43. Due to its bidirectional thread Characteristics: when it rotates, the two clamping plates 41 connected to it can make horizontal movements in opposite directions, so as to realize the clamping or loosening adjustment of bearings of different sizes and meet diverse processing needs. The outer side of the bidirectional screw 42 is threadedly connected to the inner wall of the clamping plate 41, and a drive motor 43 is provided on the front side of the lifting plate 4 to provide a power source for the rotation of the bidirectional screw 42. It is a self-locking DC reduction motor, which is an existing technology, so it will not be described in detail in this case. The rear side of the output shaft of the drive motor 43 is fixedly connected to the front side of the bidirectional screw 42.

[0036] Furthermore, the clamping block 55 is arranged at the vertical center line of the slide 51, and the center line of the slide 51 is aligned with the center line of the boring tool 2. There are two groups of clamping slots 56, and the two groups of clamping slots 56 are respectively opened at the vertical center line of the support platform 5, so that the support platforms 5 of different specifications can always be aligned with the boring tool 2, thereby improving the processing and use efficiency. The outer side of the clamping block 55 away from the slide 51 is set to an arc surface, which is convenient for the clamping block 55 to enter the inner wall of the clamping slot 56. A stabilizing bar is provided on the upper side of the lifting plate 4, and the stabilizing bar slides through the inner wall of the fixed frame 7 to improve the stability of the lifting plate 4 during movement.

[0037] Reference Figure 2 and Figure 5 An auxiliary component is provided at the front right side of the casing 1, and the auxiliary component includes a baffle 61, which can block chips and provide protection during the bearing processing. The baffle 61 is rotatably connected to the inner wall of the casing 1, and the lower side of the baffle 61 is attached to the outer side of the casing 1. A baffle rod 62 is fixedly connected to the inner wall of the casing 1 near the rear side of the baffle 61, which is used to limit the rotation angle of the baffle 61. The baffle rod 62 slides on the inner wall of the baffle 61, and the inner wall of the baffle 61 is slidably connected to a limiting member 64, which is used in conjunction with the limiting hole 65 on the baffle rod 62. Under the elastic force of the compression spring 63, the lower side of the limiting member 64 can be embedded in the limiting hole 65 to limit the rotation of the baffle 61.

[0038] The locking member 64 is engaged with the locking member 64 to prevent the locking member 64 from sliding downwards and the locking member 64 from sliding out of the locking position.

[0039] Working principle: When in use, select a suitable support 5 according to the specifications of the bearing to be processed, insert the support 5 on the outside of the slide 51, and push the support 5 so that the center of the support 5 is roughly the same as the center of the slide 51. At this time, start the electric telescopic rod 52, and the output shaft of the electric telescopic rod 52 retracts, pulling the fixed plate 53 to move, so that the hinged plates 54 connected to the left and right sides of the fixed plate 53 will rotate accordingly with the linear movement of the fixed plate 53, and then drive the block 55 to slide out of the inner wall of the slide 51, and the block 55 is smoothly inserted into the slot 56 opened on the inner wall of the middle part of the support 5 through the arc surface, thereby limiting the movement of the support 5, and firmly fixing the support 5 on the slide 51, providing a stable placement platform for the bearing.

[0040] At this time, according to the specifications of the support platform 5, the drive motor 43 is started, and its output shaft drives the bidirectional screw 42 to rotate, driving the two sets of clamping plates 41 to slide horizontally in opposite directions, and clamping the bearing from the top of both sides of the bearing to prevent the bearing from shaking and other unstable conditions during the subsequent boring process, further fixing the position of the bearing, meeting the clamping requirements of bearings of different sizes, and ensuring processing accuracy.

[0041] When it is necessary to open the baffle 61, external force can be applied to overcome the elastic force of the compression spring 63, so that the limit member 64 is disengaged from the limit hole 65, thereby realizing the rotation operation of the baffle 61, and the rotated baffle 61 is tilted and supported by the casing 1, thereby facilitating the operator to clean up the debris in the working area of ​​the casing 1.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
