Description

Technical Field

[0001] The present invention relates to the technical field of machining, and in particular to a control and holding tool based on planetary carrier machining. Background Art

[0002] Since the quality of the planetary carrier directly affects the smooth operation and reliability of the planetary gear transmission mechanism, in order to ensure the correct meshing of the sun gear, planet gears, and ring gear in the planetary gear transmission mechanism, the machining position accuracy of the planetary carrier planet gear shaft holes is generally required to be relatively strict. Currently, the machining of planetary shaft holes is mainly completed on vertical machining centers. The specific processing process includes the following steps: ① Rough boring or reaming: rough machining of the planetary shaft hole; ② Semi-finishing boring: reserving a fine boring allowance; ③ Scraping the inner stop surface: inserting the tool bar into the planetary shaft hole and installing the tool to scrape the inner stop surface; ④ Finish boring.

[0003] During processing, it is fixed to the table of the vertical machining center through a fixture. The existing fixture generally includes a structure similar to a three-jaw chuck, which uses multiple jaws to position and clamp the side of the planetary carrier to ensure its fixation. For some planetary carriers with smaller thicknesses, excessive clamping force may cause deformation, while smaller forces cannot effectively perform radial positioning, which may cause axial and radial runout, affecting the processing accuracy. In addition, during the processing, in order to ensure that the tool does not contact the processing table, it is necessary to use a pad to suspend the planetary carrier. During center positioning, the planetary carrier and the pad will slide relative to each other, causing wear on the planetary carrier surface. For this reason, we designed a control and holding fixture based on planetary carrier processing. Summary of the Invention

[0004] The control and holding tooling based on planetary carrier processing proposed by the present invention solves the above-mentioned problems.

[0007] Preferably, the lower end of the side positioning column passes through the linear sliding hole and is placed between two adjacent support plates, and the lower end of the side positioning column is fixed with a lifting guide column, and the lifting guide column is slidably placed in the lifting inclined groove below the side of the support plate, and the side of the side positioning column is penetrated by a vertically distributed movable sliding hole; When the side positioning posts move inwardly along the lifting chute, the height of the side positioning posts above the upper plate decreases, and when the side positioning posts move outwardly along the lifting chute, the height of the side positioning posts above the upper plate increases.

[0008] Preferably, two sets of studs are welded to both side surfaces of the side positioning column, and two circular holes are provided on the side plate. The side plate is plugged into the two sets of studs through the circular holes, and two nuts are threadedly connected to each of the studs. The side plate is pressed between the multiple nuts, and the position of the side plate can be changed by changing the position of the nuts, thereby being suitable for positioning planetary carriers of various sizes. An arc-shaped portion is provided at one end of the side plate away from the side positioning column, and the arc-shaped portion is designed to bend outward. The distance between the two arc-shaped plates on the same side positioning column gradually increases from the outside to the inside. When the side plate moves from the outside to the inside, the support plate on the planetary carrier can be clamped between the two side plates through the two arc-shaped plates, thereby limiting the deflection of the planetary carrier.

At this time, the linear fork will move inward along the linear slide groove. The linear fork moving inward will drive the side positioning column to slide inward through the push roller. The lower end of the side positioning column sliding inward will also move downward along the lifting inclined groove. When the turntable rotates counterclockwise, the linear fork can make the side positioning column move outward and upward.

[0012] Preferably, a plurality of groups of linear slide rails are provided in a circular array on the upper surface of the upper plate, and each group of the linear slide rails includes two linear rails. The plurality of support blocks are respectively slidably connected to the upper surface of the upper plate through the linear rails. A connecting shaft is installed on the outward side of the support block through a bracket, and the connecting shaft rolls up and down and is placed in a movable slide hole. When the side positioning column moves inward or outward, it can push the support block to move inward or outward together through the movable slide hole and the connecting shaft, so that the size of the circular structure formed by the plurality of support blocks can be changed according to the actual size of the multi-positioned planetary frame.

At this time, the rolling element will also move upward with the side positioning column, and the support wheel at the top of the rolling element will pass through the lifting port and be above the support block.

[0014] Preferably, a mounting base is fixed to the lower portion of one end of the linear shift fork away from the fixing sleeve through a support, a circular opening is formed through the upper and lower portions of the mounting base, the lifting column is located directly above the circular opening, a lifting spring is sleeved on the lifting column, the upper and lower ends of the lifting spring are respectively in contact with the mounting base and the fixing frame, the axis of the circular opening coincides with the axis of the lifting column, so that the lifting column can pass through the circular hole when moving downward, thereby avoiding collision between the lifting column and the mounting base; After placing a planetary carrier on the upper end of the support block, the planetary carrier will press down the rolling element under the action of its own gravity, and the rolling element will contact the lower surface of the planetary carrier under the action of the lifting spring. When positioning the first planetary carrier, the side positioning column moves inward and contacts the side of the planetary carrier. During the positioning process, the upper surface of the support wheel is always in contact with the lower surface of the planetary carrier.

By setting a rolling piece that slides up and down in the support block, the rolling piece can move and rise and fall together with the side positioning column. When placing the planetary carrier and clamping it for positioning, the rolling piece can avoid contact between the support block and the planetary carrier, so that the planetary carrier will not contact with the support block and cause wear when it is centered.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1 - Figure 8The control and holding tooling based on the planetary frame processing includes a chassis 1, a plurality of groups of support members are arranged in a circular array above the chassis 1, an upper plate 2 is fixed on the top of the plurality of support members, and a plurality of linear slide holes 21 distributed in a circular array are formed through the upper and lower parts of the upper plate 2. A side positioning column 4 is slidably installed in the linear slide hole 21, and a pressing block 41 is installed on the top of the side positioning column 4 through a screw 411 and a nut. Side plates 43 are symmetrically arranged on both sides of the side positioning column 4. A support block 6 is slidably connected to the inward side of each group of side positioning columns 4, and the planetary frame is placed on multiple support blocks 6. Above, the side of the planetary frame abuts against multiple side positioning columns 4, and multiple clamping blocks 41 press and position the upper surface of the planetary frame. The support block 6 is slidably connected to the upper surface of the upper plate 2. The support block 6 is penetrated up and down to form a lifting port 601. A rolling member 7 is installed in the lifting port 601 for sliding up and down. The lower end of the rolling member 7 passes through the linear sliding hole 21 and is placed under the upper plate 2. An adjustment mechanism 5 is installed under the upper plate 2. The adjustment mechanism 5 is slidably connected to the side positioning column 4, and the rolling member 7 is slidably connected to the adjustment mechanism 5 up and down, and the rolling member 7 is fixed to the side positioning column 4.

[0020] Reference Figure 3 、 Figure 6 and Figure 8 Each group of support members includes two support plates 3, which are symmetrically distributed about the side positioning columns 4. A lifting inclined groove 31 is opened at the lower side of the support plate 3, and the outer end of the lifting inclined groove 31 is higher than the inner end, and a linear slide groove 32 is opened above the side of the support plate 3.

[0021] The lower end of the side positioning column 4 passes through the linear sliding hole 21 and is placed between two adjacent support plates 3, and the lower end of the side positioning column 4 is fixed with a lifting guide column 42, and the lifting guide column 42 is slidably placed in the lifting inclined groove 31 below the side of the support plate 3. The side surface of the side positioning column 4 is penetrated by a vertically distributed moving sliding hole 401. When the side positioning column 4 slides along the lifting inclined groove 31, the height of the side positioning column 4 on the upper surface of the upper plate 2 will change. When the side positioning column 4 moves inward along the lifting inclined groove 31, the height of the side positioning column 4 above the upper plate 2 is reduced. When the side positioning column 4 moves outward along the lifting inclined groove 31, the height of the side positioning column 4 above the upper plate 2 is increased.

[0022] Two sets of studs 432 are symmetrically welded to the outer surface of the side positioning column 4. Two circular holes are provided on the side plate 43. The side plate 43 is inserted into the two sets of studs 432 through the circular holes. Two nuts are threadedly connected to each stud 432. The side plate 43 is pressed between the multiple nuts. By changing the position of the nuts, the position of the side plate 43 can be changed, thereby being suitable for positioning planetary carriers of various sizes. An arc-shaped portion 431 is provided at one end of the side plate 43 away from the side positioning column 4. The arc-shaped portion 431 is designed to bend outward. The distance between the two arc-shaped plates 431 on the same side positioning column 4 gradually increases from the outside to the inside. When the side plate 43 moves from the outside to the inside, the support plate on the planetary carrier can be clamped between the two side plates 43 through the two arc-shaped plates 431, thereby limiting the deflection of the planetary carrier.

[0023] Reference Figure 3 - Figure 8 The adjusting mechanism 5 includes a mounting shaft 52 rotatably installed between the upper plate 2 and the chassis 1 through a bearing. A turntable 51 is fixed to the upper end of the mounting shaft 52. A plurality of drive grooves 511 distributed in an annular pattern are provided on the turntable 51. The drive grooves 511 are designed in an arc-shaped structure. A linear fork 54 is installed for sliding inward and outward between the two support plates 3 of the same support member. A linear wheel 542 is rotatably installed on the upper surface of the inward end of the linear fork 54 through an axis pin. The linear wheel 542 rolls and extends into the drive groove 511.

[0024] The linear shift fork 54 includes a straight rod and two side rods located at the outer ends of the straight rod. The three are distributed in a Y-shaped structure, and the two side rods of the linear shift fork 54 are close to the two support plates 3. A plurality of linear guide rods 541 are provided on the side. The linear guide rods 541 are slidably inserted into the linear slide groove 32. A push roller 55 is provided between the two side rods, and the push roller 55 is slidably inserted into the movable slide hole 401 to limit the linear movement of the linear shift fork 54. The intersection of the axes of the multiple linear shift forks 54 coincides with the axes of the chassis 1 and the upper plate 2.

[0025] A driving rod 53 is rotatably mounted on the upper end of the chassis 1 through a bearing seat. A driving bevel gear 531 is mounted on the end of the driving rod 53 close to the mounting shaft 52. A driven bevel gear 521 is mounted on the mounting shaft 52. The driving bevel gear 531 meshes with the driven bevel gear 521. A handwheel is mounted on the driving rod 53 or connected to an external driving device. The driving rod 53 and the driving bevel gear 531 can rotate the mounting shaft 52 and the driven bevel gear 521, thereby rotating the turntable 51. When the turntable 51 rotates clockwise, the linear wheel 542 will move along the driving groove 511 close to the axis of the turntable 51. At this time, the linear shift fork 54 will move linearly inward along the linear slide groove 32. The linear shift fork 54 moving linearly inward will drive the side positioning column 4 to slide inward through the push roller 55. The lower end of the side positioning column 4 sliding inward will also move downward along the lifting inclined groove 31, that is, the side positioning column 4 can move inward and downward. At this time, the movable sliding hole 401 on the side of the side positioning column 4 slides along the push roller 55. When the rotary disk 51 rotates counterclockwise, the linear shift fork 54 can move the side positioning column 4 outward and upward.

[0026] Reference Figure 2 、 Figure 8 The upper surface of the upper plate 2 is provided with multiple sets of linear slide rails in a circular array, and each set of linear slide rails includes two linear rails 62. Multiple support blocks 6 are slidably connected to the upper surface of the upper plate 2 through the linear rails 62. The outward side of the support block 6 is installed with a connecting shaft 61 through a bracket. The connecting shaft 61 rolls up and down and is placed in the movable slide hole 401. When the side positioning column 4 moves inward or outward, it can push the support block 6 to move inward or outward together through the movable slide hole 401 and the connecting shaft 61, so that the positions of the multiple support blocks 6 can be changed according to the actual size of the multi-positioned planetary carrier, and the planetary carrier can be supported and fixed, and the support block 6 will not be in the shaft hole of the planetary carrier, and will not interfere with the boring of the planetary carrier.

[0027] Reference Figure 6 - Figure 8 , the linear fork 54 is formed with a circular hole through the upper and lower parts, and the rolling element 7 includes a lifting column 72 that is slidably inserted into the circular hole. The top of the lifting column 72 is rotatably mounted with a support wheel 71 through an axle pin. The support wheel 71 slides up and down and extends into the lifting port 601. A fixing bracket 73 is fixed to the lower part of the lifting column 72. The end of the fixing bracket 73 away from the lifting column 72 is integrally formed with a fixing sleeve 731. The fixing sleeve 731 is slidably sleeved on the side positioning column 4, and the two are fixed by bolts. Since the rolling element 7 is fixed to the side positioning column 4 through the fixing frame 73, when the side positioning column 4 moves outward and away from the planetary carrier, the side positioning column 4 will move outward and upward. At this time, the rolling element 7 will also move upward with the side positioning column 4. The support wheel 71 at the top of the rolling element 7 will pass through the lifting port 601 and be above the support block 6. After the planetary carrier is placed above the support wheel 71, it is supported by the support wheel 71. When the support block 6 moves inward, the support block 6 will not directly contact the lower surface of the planetary carrier, thereby avoiding scratches and wear.

[0028] When the side positioning column 4 moves inward and downward, the support wheel 71 will move downward with it. After the side positioning column 4 contacts the outer surface of the planetary carrier, the top of the support wheel 71 is flush with the upper surface of the support block 6. The weight of the planetary carrier is concentrated on the support block 6, increasing the contact area between the two, so that the pressure of the clamping block 41 on the planetary carrier is dispersed to multiple support blocks 6, making it evenly stressed, avoiding pressure loss caused by line and surface contact with the support wheel 71, and also making it less likely to shake through stability.

[0029] The lower part of the linear fork 54 away from the fixing sleeve 731 is fixed with a mounting base 75 by a support. The mounting base 75 is formed with a circular opening from top to bottom. The lifting column 72 is located just above the circular opening. A lifting spring 74 is sleeved on the lifting column 72. The upper and lower ends of the lifting spring 74 abut against the mounting base 75 and the fixing frame 73 respectively. The axis of the circular opening coincides with the axis of the lifting column 72, so that the lifting column 72 can pass through the circular hole when moving downward, thereby avoiding collision between the lifting column 72 and the mounting base 75. After a planet carrier is placed on the upper end of the support block 6, the planet carrier will press down the rolling element 7 under the action of its own weight, and the rolling element 7 will contact the lower surface of the planet carrier under the action of the lifting spring 74. When positioning the first planet carrier, the side positioning column 4 moves inward to contact the side of the planet carrier. During the positioning process, the upper surface of the support wheel 71 is always in contact with the lower surface of the planet carrier. After the positioning is completed, the upper surface of the support wheel 71 is flush with the upper surface of the support block 6, and then the fixing sleeve 731 is fixed to the side positioning column 4 by bolts. When the side positioning column 4 is away from the planetary frame, the support wheel 71 will move up and push out the lifting port 601 to be above it, and the tooling adjustment of the planetary frame of the same size model can be completed. The simultaneous adjustment method is adopted to make it suitable for the clamping and positioning of planetary frames of various sizes.

[0030] Working principle: The driving rod 53 is connected to the handwheel or the driving device according to actual needs. The driving device is a reduction motor or other rotating device.

[0031] In actual use, the planet carrier is initially positioned by placing it on the rolling element 7. The planet carrier will press the rolling element 7 downward under its own gravity, and the lower surface of the planet carrier will contact the support block 6. The rolling element 7 will contact the lower surface of the planet carrier under the action of the lifting spring 74. Then, the driving rod 53 is rotated clockwise, and the driving rod 53 will make the mounting shaft 52 and the driven bevel gear 521 rotate clockwise through the active bevel gear 531, thereby making the turntable 51 rotate clockwise. When the turntable 51 rotates clockwise, the linear wheel 542 will move along the driving groove 511 close to the axis of the turntable 51. At this time, the linear shift fork 54 will move linearly inward along the linear slide groove 32. The linear shift fork 54 moving linearly inward will drive the side positioning column 4 to slide inward through the push roller 55. The lower end of the side positioning column 4 sliding inward will also move downward along the lifting chute 31. Multiple side positioning columns 4 will move inward and downward synchronously. Multiple side positioning columns 4 moving inward will clamp the planetary carrier so that the center of the planetary carrier is positioned at the center of the tooling. Then, the fixing sleeve 731 is fixed to the side positioning column 4 by bolts, so that the rolling element 7 and the side positioning column 4 are connected as a whole. When the side positioning column 4 moves outward away from the planetary carrier and is released from its positioning, the support wheel 71 can extend partly above the support block 6. After the planetary carrier is placed above the support wheel 71, it is supported by the support wheel 71. When the support block 6 moves inward, the support block 6 will not directly contact the lower surface of the planetary carrier, thereby avoiding scratches and wear. Insert multiple side panels 43 onto the studs 432 of the side positioning columns 4 so that the inward side of the side panels 43 abuts against the support plate of the planetary carrier, and then fix the side panels 43 with nuts; Then, a nut is screwed onto each of the screw rods 411, and a clamping block 41 is sleeved on the screw rod 411 so that the bottom end of the clamping block 41 contacts the upper surface of the planetary carrier. Another nut is screwed onto the screw rod 411 so that the clamping block 41 is tightly pressed against the upper surface of the planetary carrier. Then, the lower nut is screwed upward so that the lower nut contacts the lower surface of the clamping block 41. At this time, the clamping and fixation of a type of planetary carrier can be completed, and no further adjustment is required when clamping and fixing this type of planetary carrier.

[0032] When it is necessary to clamp and fix planetary carriers of different models, first loosen the bolts on the fixing sleeve 731 so that the support wheel 71 and the fixing sleeve 731 can slide on the side positioning column 4, remove the side plate 43 and the clamping block 41, and then clamp and fix the planetary carrier according to the above adjustment method, so that different types of planetary carriers can be clamped and fixed as needed.

[0033] When the adjustment is completed, when repeatedly clamping and fixing multiple planetary carriers of the same model, the planetary carrier is first placed on the rolling element 7, and then the driving rod 53 is rotated clockwise by the hand wheel or driving device. The same as the above operation, when the driving rod 53 rotates clockwise, multiple side positioning columns 4 will move inward and downward. When the side positioning columns 4 move inward and downward, the pressing block 41, the side plate 43 and the supporting wheel 71 will follow the side positioning columns 4. Multiple side positioning columns 4 will push the planetary carrier to perform center positioning, and the supporting wheel 71 will move downward and extend into the supporting block 6, so that the planetary carrier is on the supporting block 6, and the pressing block 41 will also be pressed onto the upper surface of the planetary carrier, pressing the upper surface thereof for radial limitation, and the side plate 43 will also be inserted into the bracket of the planetary carrier to perform axial positioning of the planetary carrier, thereby completing the radial and axial positioning of the planetary carrier, and subsequent processing can be carried out.

[0034] By linearly slidingly arranging a plurality of side positioning columns 4 and side plates 43 above the upper plate 2, and providing an adjustable pressing block 41 above the side positioning columns 4, and cooperating with the provided lifting chute 31 and the adjustment mechanism 5, the side positioning columns 4, the side plates 43, and the pressing block 41 can move inward and downward or outward and upward, thereby enabling rapid axial and radial positioning of the planetary carrier, maintaining stability during machining, improving machining accuracy, and being suitable for rapid positioning of planetary carriers of various sizes; By slidingly setting a plurality of annular support blocks 6 on the upper plate 2, and the support blocks 6 are slidably connected to the side positioning columns 4, the side positioning columns 4 can move the support blocks 6 together during the movement process, so that the support blocks 6 are suitable for supporting and suspending planetary carriers of various sizes, avoiding collision between the tool and the tooling during processing, and the support blocks 6 will not be in the shaft hole of the planetary carrier, and will not interfere with the boring of the planetary carrier; By setting a rolling member 7 that slides up and down in the support block 6, the rolling member 7 can move and rise and fall together with the side positioning column 4. When the planetary carrier is placed and clamped for positioning, the rolling member 7 can avoid contact between the support block 6 and the planetary carrier, so that the planetary carrier will not contact with the support block 6 and cause wear when it is centered. The rolling member 7 can also be adjusted in position as needed, making it suitable for planetary carriers of various sizes and having diversity.

[0035] During processing, adjust the cutter head of the machine tool to bore the fixed planetary carrier; When the processing is completed, the turntable 51 is rotated counterclockwise by the driving rod 53. When the turntable 51 rotates counterclockwise, the linear wheel 542 will move away from the axis of the turntable 51 along the driving groove 511. At this time, the linear shift fork 54 will move outward along the linear slide groove 32. The linear shift fork 54 moving outward will drive the side positioning column 4 to move outward and upward through the pushing roller 55. When the side positioning column 4 drives the side plate 43 to move outward and upward, since the rolling element 7 is fixed to the side positioning column 4 by the fixing frame 73, when the side positioning column 4 moves toward the upper left, the rolling element 7 will also move toward the upper left, which can push the planetary carrier upward so that the lower surface of the planetary carrier and the support wheel 71 are away from the planetary carrier. When the side positioning column 4, the side plate 43, and the pressing block 41 are all away from the planetary carrier, and the circular structure formed by the inward end of the multiple pressing blocks 41 is larger than the outer diameter of the planetary carrier, the planetary carrier can be removed at this time.
