Description

Technical Field

[0001] The present invention relates to the technical field of bearing drilling, and in particular to an outer ring drilling device for bearing processing. Background Art

[0002] Bearings are key components in mechanical equipment, primarily used to secure and support rotating bodies such as shafts and gears, ensuring they operate in the correct position and preventing displacement or vibration. Through rolling or sliding contact, they convert sliding friction during movement into rolling friction, significantly reducing energy loss and improving mechanical efficiency. They can also withstand radial or axial loads, maintaining smooth operation and avoiding precision deviations caused by friction. The outer ring is the core component of a rolling bearing, typically fixed to the bearing seat or mechanical housing. Its primary function is to support the rolling elements, transfer loads, and maintain bearing structural stability. In some cases, drilling the outer ring is necessary to meet functional or installation requirements. For example, drilling holes in the outer ring creates lubricant channels, allowing grease to be directly injected into the rolling elements or raceways, reducing frictional heat and wear and extending bearing life. Alternatively, when a bearing needs to be secured with jackscrews, bolts, or eccentric sleeves, drilling holes in the outer ring facilitates the installation of fasteners.

[0003] The patent document with announcement number CN117817012B discloses a bearing outer ring drilling machine for bearing processing, wherein both sides of the stripping device are fixedly connected with side connecting bent rods, the bottom of the curved top frame is fixedly connected to the top of the annular frame, one end of the side connecting bent rod is fixedly connected to the outer surface of the annular frame, the bottom of the side connecting bent rod is fixedly connected to the centering device, the inner wall of the annular frame is fixedly connected with a lower oblique ring piece, the outer surface of the lower oblique ring piece is provided with an inclined circular hole, and the inner wall of the lower oblique ring piece is fixedly connected with a curved barb. The bearing outer ring drilling machine for bearing processing uses the lower oblique ring piece to slide and scrape the drill bit surface to prevent the drill bit from drilling for a long time and a large amount of debris adhering to the surface affecting the subsequent drilling quality, and uses the upper oblique ring piece to slide and scrape the drill bit surface and the surface of the driving shaft of the first telescopic rod to prevent dust adhering to the drill bit surface and the surface of the driving shaft of the first telescopic rod from causing jamming and damage to parts.

[0004] However, this solution also presents the following issues: The prior art can only drill one bearing at a time, and the mounting process is cumbersome, impacting processing efficiency. Furthermore, when drilling the outer ring of a bearing, multiple holes must be drilled in a symmetrical pattern. Conventional drilling methods cannot guarantee a uniform distribution of holes, which also impacts processing efficiency and drilling quality. Summary of the Invention

[0005] The present invention provides an outer ring drilling device for bearing processing, aiming to solve the problems in the related art of only being able to process one bearing at a time and having low efficiency when drilling in multiple directions.

[0006] The outer ring drilling equipment for bearing processing of the present invention includes a fixture and a drilling machine assembled on a machine tool. The fixture includes two groups of control panels arranged at intervals, with each group consisting of two control panels. Two clamping rollers are assembled on each control panel, and the control panel is rotatably arranged on the machine tool. The machine tool and the control panel are respectively provided with: a driving member 1 connected to the clamping roller and used to drive the clamping roller to rotate, and a driving member 2 connected to the control panel and used to drive the control panel to rotate; a material preparation assembly is provided on the machine tool, and the material preparation assembly is arranged above the control panel and connected to the control panel. Coordination; the corresponding states when the two control plates rotate are: the loading position with the upper end opened, the clamping position parallel to each other, and the unloading position with the lower end opened. Multiple groups of receiving rods are placed in the material preparation component, and each receiving rod is provided with multiple bearings to be processed. When in the loading position, the control plate drives the material preparation component to open so that the receiving rod moves to the clamping roller. When in the clamping position, the clamping roller abuts against the receiving rod to clamp the receiving rod. When in the unloading position, the receiving rod is separated from the clamping roller. The drilling rig is horizontally slidably assembled on the machine tool to drill holes in multiple bearings on the receiving rod respectively.

[0007] After the machining is completed, the control plate is rotated to the unloading position, so that the clamping roller is away and the receiving rod is moved out of the control plate. By setting the control plate to rotate to different positions, the receiving rod can be fixed. At the same time, the receiving rod is driven to rotate by the clamping roller on the rotating shaft of the receiving rod. The position of the drilling can be adjusted. At the same time, multiple bearings can be processed at a time, thereby improving processing efficiency.

[0009] The effect is that when the control plate rotates to the loading position, the two lower clamping rollers abut against each other, and the control plate continues to rotate, driving the slider to move in the slide groove, so that the distance between the two upper clamping rollers gradually increases, so that the receiving rod can enter between the clamping rollers for subsequent clamping and fixing.

[0010] Preferably, the second driving member includes a power member and a driving shaft, the driving shaft is connected to the control board, the power member is connected to the slider, the output end of the power member is connected to the driving shaft, and the power member drives the control board to rotate through the driving shaft.

[0011] The effect is that the driving member drives the driving shaft to rotate, and the driving shaft drives the control plate to rotate, thereby adjusting the position of the control plate.

[0012] Preferably, a limit assembly is provided on the mounting frame, and the limit assembly includes: a limit rod that cooperates with the rotation of the slider, a limit block provided on the limit rod, a connecting rod 1 vertically connected to the limit rod, and a push rod 1 vertically connected to the driving shaft. A slot is provided on the mounting frame, and a block is provided in the slot. The movement of the slider drives the limit rod to slide in the slot, and a pair of limit blocks are provided at intervals along the length direction of the limit rod. When the limit block and the block are in the same sliding direction, the block is clamped between the limit rod to fix the slider. When the driving shaft rotates, it drives the push rod 1 to cooperate with the connecting rod 1, and the push rod 1 drives the limit rod to rotate through the connecting rod 1. When the limit rod rotates and drives the limit block and the block to be misaligned, the restriction on the slider is released.

[0013] The effect is that in the initial state, the limit block cooperates with the card block, and the slider is fixed by the limit rod, and then the control plate is fixed to improve the stability of the clamping roller and the receiving rod when they cooperate. When the control plate needs to be adjusted, the drive shaft rotates to drive the push rod 1 to cooperate with the connecting rod 1 and drive the limit rod to rotate, so that the limit block is separated from the card block, and the restriction on the slider is released. The position of the control plate can be adjusted for loading or unloading.

[0014] Preferably, a connecting rod 2 is provided on the side of the limit rod, and the connecting rod 2 and the connecting rod 1 are arranged on the same straight line. A push rod 2 is provided on the drive shaft, and the push rod 2 is axially spaced apart from the push rod 1 and corresponds to the connecting rod 2. The push rod 2 is arranged vertically to the push rod 1. When the control plate rotates to the upper material position, the push rod 1 cooperates with the connecting rod 1, and when the control plate rotates to the lower material position, the push rod 2 cooperates with the connecting rod 2.

[0015] The effect is that push rod 1 is set to correspond to connecting rod 1, and push rod 2 is set to correspond to connecting rod 2, so that when the control plate is rotated to the upper material position or the lower material position respectively, the limit rod is driven to rotate by push rod 1 and push rod 2 respectively to release the restriction on the slider.

[0017] The effect is that the rotation of the shaft drives the push rod one or the push rod two to rotate. After the limit block is separated from the card block through the limit rod and the restriction on the slider is released, the top block one cooperates with the top block two, and the shaft continues to rotate to drive the control plate to rotate through the shaft sleeve, that is, before the restriction on the slider is released, the control plate is stationary, reducing the phenomenon of the slider interfering with the rotation of the control plate.

[0018] Preferably, a plurality of groups of limiting blocks are arranged at intervals along the length direction of the limiting rod, and the limiting blocks at different positions cooperate with the clamping blocks to fix the slider at different positions in the sliding groove.

[0019] The effect is that the multiple groups of limit blocks restrict the sliders to different positions, so that the control panel can fix supporting rods of different sizes.

[0020] Preferably, a reset member connected to the limiting rod and the sliding block is provided at the connection between the limiting rod and the sliding block, and the reset member is used to drive the limiting block to rotate to be in the same sliding direction as the locking block.

[0021] The effect is that after the control plate rotates to the clamping position, the slider moves to the initial position, and the reset member drives the limit block to cooperate with the clamping block to restrict the slider and improve the stability when clamping the receiving rod.

[0022] Preferably, the material preparation assembly includes: a placement frame installed on the machine tool, a baffle slidably assembled at the bottom of the placement frame, and a stopper arranged at the bottom of the baffle, the stopper cooperates with the control panel, and when the material is loaded, the control panel drives the baffle to move and open the placement frame through the stopper.

[0023] The effect is that when the control plate rotates to the loading position, it drives the baffle to move, so that the receiving rod enters between the two control plates and cooperates with the clamping roller.

[0024] Preferably, the stop block is assembled on the baffle for sliding up and down. The baffle is provided with a second elastic member connected to the stop block and used to drive the stop block to move downward. A slope is provided on the side of the stop block. When the control plate rotates from the loading position to the clamping position, it cooperates with the slope. The control plate drives the stop block to slide upward through the slope. When the control plate rotates to the clamping position, it abuts against the side of the stop block away from the slope. The baffle is provided with a third elastic member connected to the placement frame. The third elastic member is used to drive the baffle to move toward the placement frame.

[0025] The effect is that when the control plate rotates to the clamping position, the control plate cooperates with the inclined surface to simultaneously drive the stopper to move upward until the control plate and the stopper are separated, thereby reducing the phenomenon of the stopper interfering with the rotation of the control plate.

[0026] Beneficial effects: The present invention provides a clamping roller on the control panel. When the control panel is rotated and opened, the receiving rod enters between the clamping rollers, and then the control panel is rotated to the clamping position, so that the clamping roller abuts against the side of the rotating shaft of the receiving rod.

[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0039] like Figures 1 to 10 As shown, the outer ring drilling equipment for bearing machining of the present invention comprises a fixture 2 mounted on a machine tool 1, a driver 1 3, a driver 2 4, a stock preparation assembly 5, an auxiliary assembly 6, and a drilling rig 05 slidably mounted on the machine tool 1, with the drilling rig 05 being arranged to slide horizontally. Driver 1 3 and driver 2 4 both cooperate with fixture 2. Fixture 2 is used to clamp a receiving rod 01, which is sleeved with multiple bearings 02 along its length. Driver 1 3 drives the receiving rod 01 in rotation, driver 2 4 controls the fixture 2 in holding the receiving rod 01, stock preparation assembly 5 transfers the receiving rod 01 into fixture 2, and auxiliary assembly 6 cooperates with fixture 2 to assist fixture 2 in holding the rotating shaft of receiving rod 01. After fixture 2 clamps the rotating shaft of receiving rod 01, drilling rig 05 is moved along the length of receiving rod 01 to sequentially drill holes in multiple bearings 02. Driver 1 3 then rotates receiving rod 01 to adjust the position of the drilled holes.

[0040] Reference Figure 2 、 Figure 3The connecting rod 01 is symmetrically provided with a fixing plate 03 and a clamping plate 04 around its center. The fixing plate 03 is fixedly connected to the connecting rod 01. A threaded groove 011 is provided on the connecting rod 01, and the clamping plate 04 is threadedly engaged with the threaded groove 011. Before processing, multiple bearings 02 are placed on the connecting rod 01 so that the bearings 02 at the edges abut against the fixing plate 03. Then, the clamping plate 04 is placed on the connecting rod 01. After the clamping plate 04 engages with the threaded groove 011, the clamping plate 04 is rotated so that the clamping plate 04 abuts against the bearings 02. That is, the clamping plate 04 and the fixing plate 03 cooperate to clamp the bearings 02, thereby fixing the bearings 02 on the connecting rod 01.

[0041] Reference Figure 2 、 Figure 4 、 Figure 6 The fixture 2 includes a control panel 21 and clamping rollers 22. Two groups of control panels 21 are arranged on the left and right sides of the machine tool 1, with two control panels 21 forming a group. The two control panels 21 in each group are spaced apart from each other. Two clamping rollers 22 are provided on each control panel 21. The two clamping rollers 22 are assembled on the control panel 21 at intervals from top to bottom. The clamping rollers 22 rotate in coordination with the control panel 21. The control panel 21 is rotatably arranged on the machine tool 1. The rotation axis of the control panel 21 is arranged in the horizontal direction, and the rotation axes of the two control panels 21 in each group are parallel to each other. A driving member 3 is provided on the control panel 21. The driving member 3 is connected to the clamping rollers 22 to drive the clamping rollers 22 to rotate. The driving member 24 is provided on the machine tool 1 to drive the control panel 21 to rotate. The clamping rollers 22 abut against the receiving rod 01 to drive the receiving rod 01 to rotate. The material preparation assembly 5 is provided above the control panel 21, and the control panel 21 cooperates with the material preparation assembly 5. Two groups of clamping rollers 22 are provided, with each group consisting of two. This means that during drilling, four clamping rollers 22 are arranged circumferentially around the side of the receiving rod 01, simultaneously clamping the receiving rod 01 and providing a stable grip. Furthermore, the second drive element 4 is configured as a self-locking motor. After the second drive element 4 drives the control plate 21 and the clamping rollers 22 to rotate and clamp the receiving rod 01, it prevents the control plate 21 from rotating, thereby preventing the clamping rollers 22 from opening during drilling, thereby ensuring stable grip of the clamping rollers 22. Furthermore, the provision of the second drive element 4 allows for control of the rotation angle of the bearing 02, ensuring even distribution of the drilled holes when multi-directional drilling of the bearing 02 is required.

[0042] The driving member 24 drives the control plate 21 to rotate synchronously. The corresponding states of the two control plates 21 in each group when they rotate are summarized as follows: when the two control plates 21 rotate so that their upper ends move away from each other and open, the control plates 21 are in the loading position; when the two control plates 21 rotate to be parallel to each other, they are in the clamping position of the control plates 21; when the two control plates 21 rotate so that their lower ends move away from each other and open, the control plates 21 are in the unloading position.

[0043] When the control plate 21 rotates to the loading position, the gap at the upper end of the control plate 21 increases, the material preparation assembly 5 opens, and the receiving rod 01 moves between the clamping rollers 22 through the control plate 21. The control plate 21 then rotates to the clamping position, and multiple clamping rollers 22 simultaneously abut against the rotating shaft of the receiving rod 01, clamping and securing the receiving rod 01. After drilling is completed, the control plate 21 rotates to the unloading position. At this time, the gap at the lower ends of the two control plates 21 increases, and the clamping rollers 22 at the lower end move away from the rotating shaft of the receiving rod 01, releasing the clamping of the receiving rod 01, allowing the receiving rod 01 to separate from the control plate 21 and unloading. The receiving rod 01 will be slightly offset when it falls. The center of the clamping roller 22 is set to be parallel to the moving direction of the drilling rig 05. When multiple clamping rollers 22 clamp the receiving rod 01 at the same time, the center line of the receiving rod 01 will be parallel to the moving direction of the drilling rig 05, thereby correcting the position of the receiving rod 01 to eliminate the offset caused by the receiving rod 01 falling, thereby ensuring the processing accuracy of the bearing 02.

[0044] Reference Figure 6 and Figure 7 The machine tool 1 includes a mounting frame 11, and a driving member 4 includes a power member 41 and a drive shaft 42. The power member 41 is assembled on the mounting frame 11. The power member 41 is configured as a motor. The drive shaft 42 is connected to the output end of the power member 41. The control board 21 is connected to the drive shaft 42. The control lever is assembled on the mounting frame 11 through the rotation of the drive shaft 42. The power member 41 drives the drive shaft 42 to rotate, and the rotation of the drive shaft 42 drives the control board 21 to rotate.

[0045] Reference Figure 6 and Figure 7 The drive element 3 includes a drive motor 31, a gear set 32, an intermediate sleeve 33, and a belt 34. Two belts 34 are provided corresponding to the two pinch rollers 22, and the two belts 34 are spaced apart along the length of the drive shaft 42. The intermediate sleeve 33 is rotatably mounted on the outside of the drive shaft 42. The belts 34 are mounted on the outside of the intermediate sleeve 33 and the rotating shaft of the pinch rollers 22. Both belts 34 are connected to the intermediate sleeve 33. The drive motor 31 is mounted on the control panel 21, and the gear set 32 ​​is coaxially connected to the output shaft of the drive motor 31 and the intermediate sleeve 33. The drive motor 31 drives the intermediate sleeve 33 to rotate via the gear set 32. The intermediate sleeve 33 drives the pinch rollers 22 to rotate via the belt 34, thereby driving the receiving rod 01 to rotate.

[0046] Reference Figure 4 and Figure 8A slide groove 111 is provided on the mounting frame 11, and the auxiliary component 6 includes a slider 61 and an elastic member 62. The slider 61 slides horizontally in the slide groove 111. The power member 41 is connected to the slider 61, that is, the power member 41 is assembled on the mounting frame 11 through the slider 61, and the drive shaft 42 rotates with the slider 61. The elastic member 62 is set as a spring, and the spring is set in the slide groove 111. The elastic member 62 is respectively connected to the inside of the slide groove 111 and the slider 61. The elastic member 62 is used to drive the slider 61 to move toward the direction of the receiving rod 01.

[0047] When the control plate 21 rotates to the loading position, it rotates to an inclined state, so that there is a certain distance between the two upper clamping rollers 22, allowing the rotating shaft of the receiving rod 01 to pass between the two clamping rollers 22. In order to facilitate the passage of a larger receiving rod 01 between the two clamping rollers 22, the control plate 21 rotates to drive the two lower clamping rollers 22 to abut against each other. At this time, the control plate 21 continues to rotate, driving the slider 61 in a direction away from the control plate 21, and at the same time driving the distance between the two upper clamping rollers 22 to continue to increase, so that receiving rods 01 of different sizes can be clamped between the clamping rollers 22.

[0048] Reference Figures 8 to 10 When the locking cam 71 is in the closed position, the locking cam 71 is in the closed position, and the stopper 77 is in the closed position, so that the block 71 is locked and the stopper 77 is locked.

[0049] When the control panel 21 is in the clamping position, when the limit block 72 and the clamping block 113 are in the same straight line, the clamping block 113 is located between the two limit blocks 72, and the clamping block 113 abuts the limit block 72. The clamping block 113 cooperates with the limit block 72 to restrict the limit rod 71 and the slider 61, so that the slider 61 is fixed in the slide groove 111, thereby preventing the control panel 21 from sliding with the slider 61 when in the clamping position, and improving the stability of the rotational axis of the clamping roller 22 and the receiving rod 01. When the drive shaft 42 drives the control panel 21 to rotate, the drive shaft 42 drives the push rod 1 74 to abut against the connecting rod 1 73, and the connecting rod 1 73 drives the limit rod 71 to rotate. The rotation of the limit rod 71 drives the limit block 72 to separate from the clamping block 113, releasing the restriction on the slider 61, so that the control panel 21 can move with the slider 61.

[0050] Reference Figure 8 A reset member 8 is provided on the limit rod 71. The reset member 8 is configured as a torsion spring and is located at the connection between the limit rod 71 and the slider 61. The reset member 8 is connected to the limit rod 71 and is used to drive the limit block 72 to rotate until it mates with the clamping block 113. When the control board 21 is in the clamping position, the slider 61 moves to its initial position. The reset member 8 drives the limit block 72 to mate with the clamping block 113, sliding the slider 61 and improving the stability of the engagement between the clamping roller 22 and the receiving rod 01.

[0051] Reference Figure 9 and Figure 10 There are multiple groups of limit blocks 72, and the multiple groups of limit blocks 72 are arranged at intervals along the length direction of the limit rod 71. Each group of limit blocks 72 can cooperate with the card block 113 to limit the movement of the slider 61. By cooperating with the limit blocks 72 and the card block 113 at different positions, the slider 61 is restricted to different positions, and then the spacing between the clamping rollers 22 on the two groups of control panels 21 is adjusted to clamp and fix the receiving rods 01 of different sizes.

[0052] Reference Figure 10 A connecting rod 2 75 is provided on the side of the limiting rod 71, and a push rod 2 76 is provided on the driving shaft 42. The connecting rod 2 75 and the connecting rod 1 73 are symmetrical around the center of the limiting rod 71 and are arranged on the same straight line. The push rod 2 76 and the push rod 1 74 are arranged at intervals along the length direction of the driving shaft 42. The push rod 1 74 is arranged perpendicular to the push rod 1 74, and the push rod 2 76 corresponds to the connecting rod 2 75.

[0053] When the drive shaft 42 drives the control plate 21 to rotate to the upper material position and the lower material position respectively along different directions, it drives the push rod 1 74 to cooperate with the connecting rod 1 73, and the push rod 2 76 to cooperate with the connecting rod 2 75 respectively, so that the drive shaft 42 can drive the limit rod 71 to rotate when rotating along different directions, and then drive the limit block 72 to separate from the blocking block 113, thereby releasing the restriction on the slider 61.

[0054] Reference Figure 10 The drive shaft 42 includes a shaft rod 421 and a sleeve 422. The shaft rod 421 is connected to the output end of the power member 41. The sleeve 422 is rotatably arranged on the outside of the shaft rod 421. The end of the shaft rod 421 extends to the outside of the sleeve 422. Push rod 1 74 and push rod 2 76 are both arranged on the shaft rod 421. The control board 21 is fixedly connected to the sleeve 422. A top block 1 423 is provided on the shaft rod 421, and a top block 2 424 is provided on the sleeve 422. The top block 1 423 and the top block 2 424 are spaced apart in the direction around the axis of the shaft rod 421, and there is a gap between the top block 1 423 and the top block 2 424.

[0055] In the initial state, the first push block 423 and the second push block 424 are not in contact. After the shaft 421 rotates through the first push rod 74 or the second push rod 76 to drive the limit block 72 to separate from the locking block 113, the first push block 423 is driven to abut against the second push block 424. At this time, the shaft 421 continues to rotate through the first push block 423 and the second push block 424 to drive the shaft sleeve 422 and the control plate 21 to rotate, thereby adjusting the position of the control plate 21. By releasing the restriction on the slider 61 before the first push block 423 and the second push block 424 abut, and then driving the control plate 21 to rotate after the restriction is released, the phenomenon of the slider 61 interfering with the rotation of the control plate 21 is reduced. When the upper end of the control plate 21 rotates and opens to the loading position, the lower ends of the two control plates 21 abut against each other, and at the same time drive the slider 61 to slide away from the receiving rod and compress the elastic 1 62. That is, when the control plate 21 is in the loading position, the elastic member 1 62 is in a compressed stress state, so that the two lower clamping rollers 22 abut against each other to receive the receiving rod 01. In order to ensure that the clamping rollers 22 stably receive the receiving rod 01, in this embodiment, the elastic member 1 62 uses a spring with stronger elasticity according to the weight of the receiving rod 01 to increase the abutment force between the two clamping rollers 22, so that when the receiving rod 01 falls, the two clamping rollers 22 maintain a close abutment state, preventing the two clamping rollers 22 from opening due to the impact of the receiving rod 01 falling, so as to ensure that the clamping rollers 22 receive the receiving rod 01.

[0056] Reference Figure 4 and Figure 5The material preparation assembly 5 includes a placement frame 51, a baffle 52, and a stopper 53. The placement frame 51 is set above the control panel 21. The bottom of the placement frame 51 is provided with an opening. The placement frame 51 is used to place the receiving rod 01. The baffle 52 is set to slide horizontally at the bottom of the placement frame 51. The stopper 53 is set at the bottom of the baffle 52. There are two baffles 52. When the two baffles 52 are close to each other and abut against each other, the bottom of the placement frame 51 is in a closed state. In the initial state, the control panel 21 is between the two stoppers 53. When the control panel 21 rotates to the loading position, the control panel 21 abuts against the stopper 53, driving the baffle 52 to move, so that the two baffles 52 move away from each other, opening the bottom of the placement frame 51. The receiving rod 01 in the placement frame 51 passes through the control panel 21 and enters the clamping roller 22, completing the loading.

[0057] Reference Figure 4 and Figure 5 The stopper 53 is slidably assembled on the baffle 52, and a spring piece 29 connected to the stopper 53 is provided on the baffle 52. The spring piece 29 is used to drive the stopper 53 to move downward. A slope 531 is provided on the stopper 53, and the slope 531 is provided on the side of the stopper 53 away from the other baffle 52. When the control plate 21 rotates from the loading position to the clamping position, the control plate 21 abuts against the slope 531, and the slope 531 pushes the stopper 53 to move close to the baffle 52 until the control plate 21 is separated from the stopper 53. After separation, the spring piece 29 drives the stopper 53 to move to the initial position, so that the control plate 21 can rotate through the stopper 53, reducing the phenomenon that the stopper 53 interferes with the rotation of the control rod.

[0058] Reference Figure 4 and Figure 5 A third elastic member 91 is provided on the baffle 52. The third elastic member 91 is configured as a spring. The spring is respectively connected to the outer sides of the baffle 52 and the placement frame 51. The third elastic member 91 is used to drive the baffle 52 to slide toward the other baffle 52. After the control board 21 is separated from the block 53, the third elastic member 91 drives the baffle 52 to move to the initial position, closing the bottom of the placement frame 51.

[0059] Reference Figure 4 A guide plate 92 is provided on the machine tool 1. The guide plate 92 is tilted inside the machine tool 1. The guide plate 92 is set below the control panel 21. After the drilling is completed, the receiving rod 01 falls on the guide plate 92 and rolls to the designated position through the tilted guide plate 92 so that the operator can collect it.

[0060] Reference Figure 7 A rubber sheet 221 is provided on the side of the clamping roller 22. The clamping roller 22 increases the friction between the clamping roller 22 and the rotating shaft of the receiving rod 01 through the rubber sheet 221, so as to drive the receiving rod 01 to rotate.

[0061] The implementation principle of the present invention is: by rotating the control plate 21, the control plate 21 rotates to different positions corresponding to the loading position, clamping position and unloading position respectively, that is, by rotating the control plate 21, the loading, clamping and unloading of the receiving rod 01 after processing can be realized, thereby improving the processing efficiency of the bearing 02. At the same time, the rotating shaft of the receiving rod 01 is clamped by the clamping roller 22, and the receiving rod 01 is driven to rotate by the rotating shaft of the receiving rod 01. The angle of the bearing 02 can be quickly adjusted so that different positions on the bearing 02 can be drilled. At the same time, the mobile drilling rig 05 can realize drilling of multiple bearings 02 at a single time, thereby improving the drilling efficiency.

[0062] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
