Description

Technical Field

[0001] The present invention relates to the technical field of drilling processing, and more specifically, to an integrated drilling and internal grinding device for oil injection holes of steel plate pin shafts. Background Art

[0002] As a fastener, the steel plate pin shaft plays a key role in connection and transmission in mechanical equipment. In order to facilitate subsequent oiling, an oil injection hole is drilled inside the steel plate pin shaft during the production process. For example, a drilling device for the oil injection hole of a cross shaft with the patent publication number CN212419746U includes a drilling machine and a drilling platform. A clamping member is provided on the drilling platform. The clamping member includes four supporting blocks distributed in a square shape on the drilling platform, a V-shaped groove opened on the supporting block for the shaft end of the cross shaft to abut and place, a portal bracket provided on the supporting block, and a pressing member provided on the portal bracket and used to press the shaft end of the cross shaft tightly into the V-shaped groove from top to bottom. The supporting block is slidably connected to the drilling platform. The drilling device further includes a driving device for driving each supporting block to slide simultaneously. The problem of poor applicability of the drilling device in the related art is solved. The applicable range of the drilling device is expanded through the movable and adjustable supporting blocks, and the rolling of the cross shaft during the processing is reduced through the pressing member, improving the processing accuracy of the oil injection hole.

[0003] After the existing steel plate pin shaft is drilled with an oil injection hole, in order to ensure the subsequent oil outlet effect, the inner wall of the oil injection hole is also polished, making the inner wall of the oil injection hole smoother to avoid interfering with the injection of lubricating oil. However, the existing drilling device can only drill the oil injection hole. If subsequent grinding is required, the steel plate pin shaft needs to be transferred to a grinding device in sequence for internal grinding treatment. As a result, under continuous processing, the operator needs to manually replace the steel plate pin shaft frequently, resulting in general processing efficiency and increased workload for the operator.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By adjusting the cylinder, the height of the servo motor can be adjusted, and the docking of the spline shaft and the spline slot, as well as the meshing with the first transmission bevel gear and the second transmission bevel gear, can be controlled, so as to realize the processing of the processing component driven by the servo motor and the rotation of the transfer component. In this application, a loading bin and a blanking component are respectively arranged at the front and rear positions of the processing component. Cooperating with the above driving structure, the continuous transfer of steel plate pins can be realized, and the continuous feeding of steel plate pins can be realized by the continuous falling of steel plate pins in the loading bin. The processed steel plate pins can be automatically discharged through the blanking component, so that the transfer component can store new steel plate pins to realize continuous processing operations. Through the above structure, there is no need for operators to manually change the position of the steel plate pins, and during the processing of the steel plate pins, there is also no need for personnel to manually fix the steel plate pins. Therefore, this application can perform integrated processing of drilling and grinding on the steel plate pins and carry out continuous feeding operations. Compared with existing equipment, the processing efficiency of this application is improved and no manual operation is required by personnel.

[0016] 2. By adjusting the cylinder to control the first transmission bevel gear to descend and mesh with the second transmission bevel gear, when the servo motor starts, it is convenient to drive the driving lead screws on both sides to rotate. Using the threaded fit between the driving lead screw and the cooperating slide seat, the driving motors on both sides can move synchronously closer to or away from the steel plate pin, realizing automatic processing operations. By rotating the distance-adjusting lead screw and using the limit fit between the adjusting seat and the adjusting groove, when the distance-adjusting lead screw is in threaded fit with the distance-adjusting screw hole, the height of the driving motor can be adjusted, so as to match the size of the steel plate pin to be processed.

[0017] 3. When the receiving main board rotates, by arranging an arc-shaped tooth plate on the inner wall of the dislocation channel, when the arc-shaped tooth plate passes through the driven gear, meshing occurs, driving the driven gear to rotate. When the driven gear rotates, the pulling rope is wound up, pulling the movable sleeve to move to the turning hole. When the receiving main board rotates in place, the limit rotating shaft and the pushing plate are flipped and reset by the torsion spring, so that the height of the pushing plate can push the steel plate pin. During this process, the driven gear will be disconnected from the arc-shaped tooth plate. Subsequently, under the pulling of the return spring, the movable sleeve moves outwards and the pushing plate pushes the steel plate pin at the current position outwards, thus realizing automatic blanking operations; By arranging two groups of movable arc plates, with the two groups of movable arc plates respectively arranged on both sides of the transmission gear, when the transmission gear passes through one side of the movable arc plate, it meshes with the transmission teeth to realize the forward rotation of the transmission gear. Subsequently, when the transmission gear passes through the other movable arc plate, it meshes with the transmission teeth to realize the reverse rotation of the transmission gear. Through the above structure, it can be controlled that the transmission gear will automatically rotate when passing through the fixed area to drive the clamping of the clamping plate; By arranging two groups of movable arc plates, with the two groups of movable arc plates respectively arranged on both sides of the transmission gear, when the transmission gear passes through one side of the movable arc plate, it meshes with the transmission teeth to realize the forward rotation of the transmission gear. Subsequently, when the transmission gear passes through the other movable arc plate, it meshes with the transmission teeth to realize the reverse rotation of the transmission gear. Through the above structure, it can be controlled that the transmission gear will automatically rotate when passing through the fixed area to drive the clamping of the clamping plate; 4. Since the elastic force of the supporting spring is greater than the clamping force of the clamping plate, the supporting spring will contract only after the clamping plate clamps an object. This allows the transmission gear to skip the remaining transmission teeth, enabling the transmission gear to rotate to the corresponding degree each time clamping or unclamping occurs, for steel plate pin shafts of different sizes. After clamping is completed, the angle of the current transmission gear can be fixed using a spring positioning pin to prevent it from falling off during processing.

[0018] 5. Rotation of the transmission gear can drive the second mating bevel gear to rotate, causing the first mating bevel gear to mesh with the second mating bevel gear. This enables the forward and reverse lead screw to rotate inside the series channel. Utilizing the threaded fit between the lead screw body and the connecting sliding plates on both sides, the distance between the two clamping plates can be adjusted to ensure that the two clamping plates can clamp the steel plate pin shaft, thereby achieving automatic clamping and unclamping operations for the steel plate pin shaft and ensuring stability during processing.

With the above driving structure, continuous transfer of steel plate pin shafts can be realized, and continuous feeding can be realized by continuously dropping steel plate pin shafts by using the feeding bin 6. Among them, the processed steel plate pin shafts can be automatically discharged through the blanking assembly 4, so that the transfer and storage assembly 2 can store new steel plate pin shafts to realize continuous processing operations. Through the above structure, it is not necessary for the operator to manually change the position of the steel plate pin shaft, and it is also not necessary for the operator to manually fix the steel plate pin shaft during the processing of the steel plate pin shaft. Therefore, this application can perform integrated processing of drilling and grinding of steel plate pin shafts and perform continuous feeding operations. Compared with the existing equipment, the processing efficiency of this application is improved and manual operation by personnel is not required.

[0025] In this application, the processing assembly 3 includes two propulsion chutes 301. The two propulsion chutes 301 are arranged in an L shape inside the mating base 1. The two propulsion chutes 301 communicate with the middle of the adjustment rotating groove 9. Matching sliding seats 3021 are movably installed inside the two propulsion chutes 301. An extension frame 302 is fixedly installed on one side of the matching sliding seat 3021. An installation frame 303 is fixedly installed on the outside of the extension frame 302; An adjustment groove 3031 is provided inside the installation frame 303. An adjustment seat 3032 is movably installed inside the adjustment groove 3031. A driving motor 305 is respectively installed on the upper sides of the two adjustment seats 3032. Drill bits 306 and grinding heads 307 are respectively arranged at the output ends of the two driving motors 305.

[0026] Among them, a distance adjustment screw rod 304 is rotatably installed at the upper end of the mounting bracket 303. A distance adjustment screw hole 3033 is formed at the bottom of the adjustment seat 3032. The distance adjustment screw rod 304 is in threaded cooperation with the distance adjustment screw hole 3033; A bearing seat 308 is installed inside each propulsion chute 301. A driving screw rod 309 is rotatably installed inside the bearing seat 308. The rod body of the driving screw rod 309 is in threaded cooperation with the mating sliding seat 3021. A second transmission bevel gear 310 is fixedly installed at one end of the two driving screw rods 309; A first transmission bevel gear 13 is arranged on the rod body of the spline shaft 14. Each second transmission bevel gear 310 is meshed with the first transmission bevel gear 13.

[0027] By controlling the first transmission bevel gear 13 to descend through the adjustment cylinder 10 so that it meshes with the second transmission bevel gear 310, when the servo motor 12 is started subsequently, it is convenient to drive the driving screw rods 309 on both sides to rotate. By using the threaded cooperation between the driving screw rod 309 and the mating sliding seat 3021, the driving motors 305 on both sides can be synchronously close to or away from the steel plate pin shaft, realizing automatic processing operations; By rotating the distance adjustment screw rod 304, using the limit cooperation between the adjustment seat 3032 and the adjustment groove 3031, when the distance adjustment screw rod 304 is in threaded cooperation with the distance adjustment screw hole 3033, the height of the driving motor 305 can be adjusted, so as to match the size of the steel plate pin shaft to be processed.

[0028] In this application, the blanking component 4 includes a flipping groove 401. The flipping groove 401 is formed on one side of the upper surface of the mating base 1. A limit rotating shaft 402 is rotatably installed inside the flipping groove 401 through the limit of a torsion spring 4021. A limit protrusion 4022 is arranged on the rod body of the limit rotating shaft 402. A movable sleeve 404 is slidably installed on the rod body of the limit rotating shaft 402. A return spring 403 is fixedly installed between the movable sleeve 404 and one end of the limit rotating shaft 402. A push plate 4041 for discharging materials is arranged at the upper end of the movable sleeve 404.

[0029] It should be noted that a wire winding rotating groove 4051 is formed on one side of the flipping groove 401. A wire winding channel 405 is formed between the wire winding rotating groove 4051 and the flipping groove 401. A wire winding roller 406 is rotatably installed inside the wire winding rotating groove 4051. A driven gear 407 is arranged at the upper end of the wire winding roller 406; An annular groove 4042 is formed at one end of the movable sleeve 404. An arc-shaped sliding seat 4043 is slidably installed inside the annular groove 4042. A pulling rope 408 is connected between one end of the arc-shaped sliding seat 4043 and the wire winding roller 406.

[0030] When the receiving main board 201 rotates, an arc-shaped toothed plate 2015 is arranged on the inner wall of the dislocation channel 2014, so that when the arc-shaped toothed plate 2015 passes through the driven gear 407, meshing occurs, driving the driven gear 407 to rotate. Under the rotation of the driven gear 407, the winding and pulling rope 408 is wound, so as to pull the movable sleeve 404 to move to the turning hole 2012. When the receiving main board 201 rotates in place, the limit rotating shaft 402 and the pushing plate 4041 are turned back to their original positions by the torsion spring 4021, so that the height of the pushing plate 4041 can push the steel plate pin shaft. During this process, the driven gear 407 will be disconnected from the arc-shaped toothed plate 2015, and then under the pulling of the return spring 403, the movable sleeve 404 moves outwards and the pushing plate 4041 pushes the steel plate pin shaft at the current position outwards, thus realizing automatic blanking operation; When blanking is completed and the receiving main board 201 rotates again, the limit rotating shaft 402 can rotate, so that the pushing plate 4041 located in the receiving groove 2011 will turn downwards into the turning groove 401 for the next blanking.

[0031] In this application, the transfer component 2 includes four receiving main boards 201. The receiving main boards 201 are fixedly installed on the shaft body of the connecting rotating shaft 8 together. A receiving groove 2011 is opened on the body of the receiving main board 201. A turning hole 2012 for the reset of the pushing plate 4041 is opened inside the receiving groove 2011. Two lifting plates 2013 are installed on the inner wall of the receiving groove 2011; A dislocation channel 2014 is opened at the bottom of the receiving main board 201, and an arc-shaped toothed plate 2015 for meshing with the driven gear 407 is arranged on the inner wall of the dislocation channel 2014; Blocking seats 7 for blocking the feeding ports of the feeding bin 6 are arranged on both sides of the upper surface of the receiving main board 201.

[0032] Through the blocking seats 7, it is possible to prevent the steel plate pin shaft from falling from the feeding bin 6 during the rotation of the receiving main board 201, so as to ensure that the steel plate pin shaft will only fall into the receiving groove 2011 and be supported by the lifting plates 2013.

[0033] Wherein, an extension platform 105 is arranged on one side of the matching base 1. Activity grooves 101 are opened on the upper surface of the extension platform 105 and the matching base 1. Activity arc plates 103 are movably installed inside the activity grooves 101. A number of transmission teeth 106 are arranged on the surface of the activity arc plates 103. Fixed grooves 102 are opened on the inner wall of the activity grooves 101, and a support spring 104 is installed inside the fixed grooves 102 to support the activity arc plates 103.

[0034] By providing two sets of movable arc plates 103, with the two sets of movable arc plates 103 respectively arranged on both sides of the transmission gear 2043, when the transmission gear 2043 passes through one side of the movable arc plate 103, it meshes with the transmission teeth 106 to achieve the forward rotation of the transmission gear 2043. Subsequently, when the transmission gear 2043 passes through the other movable arc plate 103, it meshes with the transmission teeth 106 to achieve the reverse rotation of the transmission gear 2043. Through the above structure, it can be controlled that the transmission gear 2043 will automatically rotate when passing through the fixed area to drive the clamping of the clamping plate 2033; In order to avoid the situation where the clamping plate 2033 is excessive due to different sizes of the steel plate pin shafts, the elastic force of the support spring 104 is greater than the clamping force of the clamping plate 2033. After the clamping plate 2033 clamps, the support spring 104 will shrink, and the transmission gear 2043 can skip the remaining transmission teeth 106, so that the transmission gear 2043 can rotate to the corresponding degree each time when clamping or releasing the clamping, for steel plate pin shafts of different sizes. And after the clamping is completed, the spring positioning pin 2045 can be used to fix the angle of the current transmission gear 2043 to avoid falling off during processing.

[0035] It should be noted that adjustment sliding grooves 202 are formed on the surface of the lifting plate 2013. Columns 203 are slidably installed inside the adjustment sliding grooves 202. An activity groove 2031 is formed inside the columns 203. An auxiliary sliding seat 2032 is movably installed inside the activity groove 2031 through an auxiliary spring 2034. A clamping plate 2033 is fixedly installed at the outer end of the auxiliary sliding seat 2032.

[0036] During the clamping process, the auxiliary spring 2034 can enable the auxiliary sliding seat 2032 to move to a certain position. When the column 203 contracts and clamps, through its movable structure, the clamping plate 2033 can adapt to the position of the current steel plate pin shaft and realize subsequent clamping operations.

[0037] When specifically setting, a series connection channel 2022 is formed between the two sides of the adjustment sliding grooves 202. Connection sliding plates 2021 are respectively slidably installed on both sides of the series connection channel 2022. The connection sliding plates 2021 are fixedly connected to the corresponding columns 203. A positive and negative lead screw 2023 is rotatably installed inside the series connection channel 2022. The rod body of the positive and negative lead screw 2023 is in threaded cooperation with the connection sliding plates 2021 on both sides; A transmission groove 204 is formed in the middle of the series connection channel 2022. An extension rotating groove 2042 is formed below the transmission groove 204. A transmission gear 2043 is rotatably installed inside the extension rotating groove 2042 through a spring positioning pin 2045. A second mating bevel gear 2044 is arranged at the upper end of the transmission gear 2043. The outside of the transmission gear 2043 meshes with the adjacent transmission teeth 106; The forward and reverse lead screw 2023 is fixedly installed with a first mating bevel gear 2041 inside the transmission groove 204, and the first mating bevel gear 2041 meshes with the second mating bevel gear 2044.

[0038] The rotation of the transmission gear 2043 can drive the second mating bevel gear 2044 to rotate, enabling the first mating bevel gear 2041 to mesh with the second mating bevel gear 2044, which allows the forward and reverse lead screw 2023 to rotate inside the series channel 2022. Utilizing the threaded fit between the rod body of the forward and reverse lead screw 2023 and the connecting slide plates 2021 on both sides, the distance between the clamping plates 2033 on both sides can be adjusted to ensure that the clamping plates 2033 on both sides can clamp the steel plate pin shaft, thereby realizing the automatic clamping and releasing of the steel plate pin shaft and ensuring the stability during processing.

[0039] The working principle of this integrated processing device for drilling and internal grinding of oil injection holes on steel plate pin shafts: During use, first, automatic feeding is carried out through the feeding bin 6. After feeding, the adjusting cylinder 10 raises the servo motor 12, enabling the servo motor 12 to drive the connecting rotating shaft 8 to rotate, and then the rotating storage component 2 rotates; Through the rotation of the rotating storage component 2, the current steel plate pin shaft can be transferred to the next working station. When the steel plate pin shaft enters the processing component 3, the adjusting cylinder 10 controls the first driving bevel gear 13 to descend and mesh with the second driving bevel gear 310. Subsequently, when the servo motor 12 starts, it is convenient to drive the driving lead screws 309 on both sides to rotate. Utilizing the threaded fit between the driving lead screws 309 and the mating sliding seats 3021, the driving motors 305 on both sides can be synchronized to approach or move away from the steel plate pin shaft, and in cooperation with the drill bit 306 and the grinding head 307, processing is carried out. The drill bit 306 and the grinding head 307 are two working stations, so the steel plate pin shaft needs to move two working stations to complete the processing operation; The processed steel plate pin shaft is transferred to the discharging component 4. When the receiving main board 201 rotates, by virtue of the arc-shaped toothed plate 2015 provided on the inner wall of the dislocation channel 2014, the arc-shaped toothed plate 2015 meshes with the driven gear 407 when passing through it, driving the driven gear 407 to rotate. Under the rotation of the driven gear 407, the retracting and pulling rope 408 is wound, thereby pulling the movable sleeve 404 to move to the flipping hole 2012. When the receiving main board 201 rotates in place, the limiting rotating shaft 402 and the pushing plate 4041 are flipped and reset by the torsion spring 4021, enabling the height of the pushing plate 4041 to be able to push the steel plate pin shaft. During this process, the driven gear 407 will be disconnected from the arc-shaped toothed plate 2015. Subsequently, under the pulling of the reset spring 403, the movable sleeve 404 moves outward and the pushing plate 4041 pushes the steel plate pin shaft at the current position outward, thus realizing the automatic discharging operation.
