Description

Technical Field

[0001] This invention relates to the field of metal processing technology, specifically to a horizontal machining center for a high-precision planetary reducer planetary carrier. Background Technology

[0002] In the field of horizontal machining of planetary carriers for high-precision planetary reducers, in order to achieve multi-station batch processing, multi-station fixtures are used to fix and limit the planetary carriers. During use, positioning bolts of the same size are used to fix and limit the positioning plate, thereby limiting the planetary carriers on the positioning plate. During use, the operator needs to insert the planetary carrier into the mounting hole, manually lift the positioning plate, place the positioning block under the plate to determine the lifting height, and ensure that the heights of multiple stations are consistent. Then, adjust the positioning plate to the target position and tighten the positioning bolts to limit the plate, thereby fixing the planetary carrier. After one station is completed, the above actions of lifting the plate, placing the positioning block, and tightening the bolts are repeated until the planetary carriers of all stations are clamped.

[0003] Currently, when fixing planetary carriers at multiple workstations, operators need to repeatedly perform tedious actions at each workstation. First, they manually lift the positioning plate, pick up the positioning block and place it under the plate to determine the lifting height, then pick up a special tool to tighten the positioning bolts to rigidly limit the plate and thus fix the planetary carrier. However, the entire clamping process is time-consuming and requires personnel to repeatedly pick up and place the positioning block, which reduces the overall production efficiency.

[0004] Therefore, the purpose of this invention is to provide a horizontal machining center for a high-precision planetary gear reducer planetary carrier, in order to overcome the shortcomings of the prior art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a horizontal machining center for high-precision planetary reducer planetary carriers. This solves the problem that when fixing multi-station planetary carriers, operators must repeatedly perform tedious actions at each station. These actions involve manually lifting the positioning plate, accurately picking up the positioning block and placing it under the plate to determine the lifting height, adjusting the positioning plate to the target position that fits against the end face of the planetary carrier, and then using a special tool to tighten the positioning bolts to rigidly limit the plate. This process is cumbersome and time-consuming.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a horizontal machining center for a planetary carrier of a high-precision planetary reducer, comprising a fixed base, a movable component mounted on the fixed base, the movable component comprising a rotating shaft and a movable plate, a connecting rod fixedly connected to the lower surface of the rotating shaft, a handle fixedly connected to the lower surface of the connecting rod via a locking pin, a rotating disk fixedly connected to the upper surface of the rotating shaft, a first guide groove provided inside the movable plate, a first fixed post provided inside the first guide groove, a positioning block for limiting and positioning a pressure plate fixedly connected to the rear surface of the movable plate, and the lower surface of the fixed base...

A positioning bolt is threaded inside the internally threaded post. A connecting plate is fixedly connected to the front surface of the positioning pressure plate. A lifting part is provided at the right end of the connecting plate.

[0007] Preferably, the lower surface of the first fixed column is fixedly connected to the rotating disk, the rotating shaft is fixedly connected to the fixed seat through a bearing, the lower surface of the rotating disk is rotatably connected to the fixed seat, and the lower surface of the moving plate is slidably connected to the fixed seat.

[0008] Preferably, the locking pin can engage with the locking slot.

[0009] Preferably, the rear end of the positioning post is fixedly connected to the fixing seat.

[0010] Preferably, the fixed base has a first planetary carrier insertion hole inside, and a first processing planetary carrier is provided inside the first planetary carrier insertion hole. The diameter of the first planetary carrier insertion hole is adapted to the outer diameter of the first processing planetary carrier for radial positioning of the first processing planetary carrier. The first processing planetary carrier is used as a blank to be processed in a high-precision planetary reducer.

[0011] Preferably, the fixed base has a second planetary carrier insertion hole inside, and a second processing planetary carrier is provided inside the second planetary carrier insertion hole. The diameter of the second planetary carrier insertion hole is adapted to the outer diameter of the second processing planetary carrier for radial positioning of the second processing planetary carrier. The second processing planetary carrier is used as a blank to be processed in a high-precision planetary reducer. The outer diameter of the second processing planetary carrier is different from that of the first processing planetary carrier.

[0012] Preferably, a second fixing post is fixedly connected to the lower surface of the fixing base, and a fixing plate is fixedly connected to the lower surface of the second fixing post.

[0013] Preferably, the rear surface of the internally threaded post is fixedly connected to the fixed seat.

[0014] Preferably, the lower surface of the positioning block is slidably connected to the fixed base, and the interior of the positioning block is provided with a groove.

[0015] This invention provides a horizontal machining center for high-precision planetary reducer planetary carriers. It offers the following advantages:

[0016] 1. This invention, by setting up a moving component, a third fixed column, a rubber block, a locking column, and a locking slot, can achieve synchronous position adjustment and rapid locking of multiple sets of positioning blocks. In use, the operator can push the lifting part on one side of the connecting plate to move multiple sets of positioning pressure plates upward. After turning the handle, the multiple sets of positioning blocks move to the bottom of the positioning pressure plates, and the locking column enters the locking slot to achieve locking. The entire process does not require the operator to pick up or place the positioning blocks one by one. Only a single push and locking action is needed to complete the position adjustment of multiple sets of positioning blocks. This structure solves the problem of time-consuming repetitive operations, thereby improving the planetary carrier clamping efficiency.

[0017] 2. The present invention forms a double limit on the positioning plate by locking the positioning block and positioning bolt, which can prevent the positioning bolt from loosening slightly due to cutting vibration during processing. The positioning block can simultaneously prevent the positioning plate from sinking, further constraining the position of the positioning plate. This structure improves the processing accuracy of the planetary carrier.

[0018] 3. The handles at the front and rear of this invention ensure that they do not collide during use, and their rotation trajectories are completely staggered and do not interfere with each other. Attached Figure Description

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a horizontal machining center for a planetary carrier of a high-precision planetary reducer, including a fixed base 1. A movable component 2 is provided on the fixed base 1. The movable component 2 includes a rotating shaft 201 and a movable plate 206. A connecting rod 202 is fixedly connected to the lower surface of the rotating shaft 201. A handle 204 is fixedly connected to the lower surface of the connecting rod 202 through a locking post 203. A rotating disk 205 is fixedly connected to the upper surface of the rotating shaft 201. A first guide groove 207 is provided inside the movable plate 206. A first fixed post 208 is provided inside the first guide groove 207. A positioning block 209 for limiting and positioning a pressure plate 6 is fixedly connected to the rear surface of the movable plate 206.

[0030] The fixed base 1 is integrated on the main machine bed of the horizontal machining center. It is the basic carrier for the machining center to realize high-precision machining of planetary carriers. The fixed base 1 needs to support the clamping and positioning of the first machining planetary carrier 11 and the second machining planetary carrier 17.

[0031] The movable component 2 is used to realize the synchronous position adjustment of multiple sets of positioning blocks 209. In use, the operator can drive the connecting rod 202 and the rotating shaft 201 to rotate synchronously by turning the handle 204. This causes the rotating disk 205 on the top of the rotating shaft 201 to rotate accordingly. One end of the first fixed column 208 is fixed on the rotating disk 205, and the other end is embedded in the first guide groove 207 of the movable plate 206. The circular motion of the rotating disk 205 can be converted into the linear motion of the movable plate 206 by the first fixed column 208. This causes the multiple sets of positioning blocks 209 on the rear surface of the movable plate 206 to move synchronously. During the process, it is not necessary to adjust the positioning blocks 209 one by one. The entire process does not require the operator to pick up or place the positioning blocks 209 one by one. Only a single push action is needed to complete the position adjustment of multiple sets of positioning blocks 209. This structure solves the problem of time-consuming repetitive operations and thus improves the planetary carrier clamping efficiency.

[0032] The lower surface of the first fixed column 208 is fixedly connected to the rotating disk 205. The rotating shaft 201 is fixedly connected to the fixed seat 1 through a bearing. The lower surface of the rotating disk 205 is rotatably connected to the fixed seat 1. The lower surface of the moving plate 206 is slidably connected to the fixed seat 1. The lower surface of the positioning block 209 is slidably connected to the fixed seat 1. The positioning block 209 has a groove 21 inside. The positioning block 209 is made of 40CrNiMoA alloy structural steel, which has excellent fatigue resistance and wear resistance. It can adapt to the working conditions of long-term cutting vibration load in high-precision machining. The positioning block 209 improves its tensile strength through quenching and tempering treatment and surface nitriding treatment. The quenching and tempering treatment is quenching temperature of 850-870℃, holding temperature for 2-3 hours and then oil cooling, followed by high-temperature tempering temperature of 580-600℃ and holding temperature for 4-5 hours. The nitriding treatment is nitriding temperature of 520-540℃ and holding temperature for 6-8 hours.

[0033] The rotating shaft 201 is made of high-precision hollow spindle with 20CrMnTi carburizing and quenching treatment. It is connected to the fixed seat 1 by a high-precision angular contact ball bearing, model 7005AC, which can ensure that the coaxiality of the rotating shaft 201 is ≤0.002mm when rotating. This bearing structure can reduce the frictional resistance during rotation, ensure that the handle 204 rotates smoothly and the rotating shaft 201 has no radial offset. At the same time, the bearing plays a supporting and fixing role for the rotating shaft 201.

[0034] The sliding connection between the movable plate 206 and the positioning block 209 and the fixed base 1 further limits the movement of the positioning block 209. When the positioning block 209 slides along the fixed base 1 with the movable plate 206, its movement path interferes with the edge of the rotating disk 205. The groove 21 is opened on the side of the positioning block 209 close to the rotating disk 205. The depth and width of the groove 21 match the thickness and edge radius of the rotating disk 205, ensuring that during the translation of the positioning block 209, the edge of the rotating disk 205 can be completely embedded in the groove 21 without any contact or collision between the two.

[0035] The location of the groove 21 does not affect the precise positioning of the upper surface on the positioning plate 6. The first guide groove 207 of the moving plate 206 is machined by CNC wire cutting, with a groove wall roughness Ra≤0.4μm. The clearance between the groove and the first fixed column 208 is controlled within 0.003-0.005mm to ensure no gap or shaking during transmission. This ensures that the positional deviation of multiple positioning blocks 209 when moving synchronously is ≤0.005mm, meeting the high-precision planetary carrier clamping and positioning requirements. To adapt to the high-precision machining rhythm of the horizontal machining center, the upper surface of the fixed seat 1 is precision ground, with a flatness ≤0.002mm / m and a roughness Ra≤0.2μm. This ensures that the frictional resistance of the moving plate 206 and the positioning block 209 is uniform and small when sliding, avoiding sliding jamming caused by uneven table surface. The top limiting surface of the positioning block 209 is CNC forming grinding process, with a flatness ≤0.001mm and a roughness Ra≤0.1μm.

[0036] The fixed base 1 has a sliding groove 5 inside, and a positioning pressure plate 6 is slidably connected to the inner surface of the sliding groove 5. The positioning pressure plate 6 has a third guide groove 7 inside, and an internal threaded post 8 is provided on the inner surface of the third guide groove 7. The rear surface of the internal threaded post 8 is fixedly connected to the fixed base 1. A positioning bolt 9 is connected to the internal thread of the internal threaded post 8. A connecting plate 12 is fixedly connected to the front surface of the positioning pressure plate 6. A lifting part 13 is provided at the right end of the connecting plate 12.

[0037] The operator pulls the lifting part 13 on the right end of the connecting plate 12 upwards, which can drive multiple sets of positioning pressure plates 6 to move synchronously upwards along the slide groove 5 through the connecting plate 12. It is not necessary to lift the positioning pressure plates 6 one by one, which makes it convenient for the positioning pressure plates 6 to be quickly inserted into the center position of the planetary carrier and fixed. After the positioning block 209 limits the bottom of the positioning pressure plate 6, the positioning bolt 9 is tightened to make the positioning bolt 9 fit with the positioning pressure plate 6, which can initially fix the position of the positioning pressure plate 6. At the same time, the bottom of the positioning pressure plate 6 fits with the top of the positioning block 209. The positioning block 209 forms a second limit on the positioning pressure plate 6 through its own position. The positioning block 209 forms a lock when the locking post 203 enters the locking groove 20, which can prevent the positioning bolt 9 from loosening slightly due to cutting vibration during processing. The positioning block 209 can also prevent the positioning pressure plate 6 from sinking, further constraining the position of the positioning pressure plate 6. The positioning block 209 improves the processing accuracy of the planetary carrier.

[0038] The movable plate 206 has a second guide groove 3 inside, and a positioning post 4 is slidably connected to the inner surface of the second guide groove 3. The rear end of the positioning post 4 is fixedly connected to the fixed base 1.

[0039] The second guide groove 3 and the positioning post 4 constitute the guide structure of the moving plate 206. The second guide groove 3 and the positioning post 4 work together to constrain the movement trajectory of the moving plate 206. The positioning post 4 is fixed on the fixed base 1 and slides with the second guide groove 3. When the moving plate 206 moves with the rotating disk 205, it moves along the axial direction of the positioning post 4 to avoid lateral displacement of the moving plate 206 due to the gap between the first fixed post 208 and the first guide groove 207. The second guide groove 3 and the positioning post 4 form a guide for the transmission structure of the rotating disk 205 and the first fixed post 208, ensuring that when multiple sets of positioning blocks 209 move synchronously, they can accurately enter the slide groove 5 and play a guiding and positioning role for the positioning pressure plate 6.

[0040] A third fixing post 18 is fixedly connected to the lower surface of the fixing base 1, and a rubber block 19 is fixedly connected to the front surface of the third fixing post 18. A slot 20 is provided inside the rubber block 19, and the locking post 203 can engage with the slot 20.

[0041] The third fixing post 18, rubber block 19, slot 20, and locking post 203 together constitute a quick-locking assembly, which is key to achieving quick locking of multiple positioning blocks 209. When the positioning block 209 moves with the moving plate 206 to the position below the positioning pressure plate 6, the operator turns the handle 204, which drives the locking post 203 on the connecting rod 202 to engage in the slot 20 of the rubber block 19, achieving instant locking of the moving assembly 2. This process does not require the operator to use additional tools. The elasticity of the rubber block 19 increases the locking post 203. The friction between the rubber block 19 and the slot 20 prevents the locking mechanism from loosening due to processing vibration. At the same time, the buffering effect of the rubber block 19 reduces the collision noise when the locking post 203 is engaged. This structure allows the locking operation of the positioning block 209 to be completed with just one turn of the handle 204. The entire process does not require the operator to pick up or place the positioning blocks 209 one by one. Only a single push and locking action is needed to complete the position adjustment of multiple sets of positioning blocks 209. This structure solves the problem of time-consuming repetitive operations, thereby improving the planetary carrier clamping efficiency.

[0042] The fixed base 1 has a first planetary carrier insertion hole 10 inside, and a first processing planetary carrier 11 is provided inside the first planetary carrier insertion hole 10. The diameter of the first planetary carrier insertion hole 10 is adapted to the outer diameter of the first processing planetary carrier 11, and is used to radially position the first processing planetary carrier 11. The first processing planetary carrier 11 is used as a blank to be processed in a high-precision planetary reducer.

[0043] The gap between the diameter of the first planetary carrier insertion hole 10 and the outer diameter of the first processed planetary carrier 11 is controlled at 0.003-0.005mm. This ensures that the first processed planetary carrier 11 can be smoothly inserted and limits the radial wobble of the planetary carrier. This radial positioning, together with the axial pressing of the positioning plate 6 passing through the first processed planetary carrier 11 and the limiting cooperation of the positioning block 209, constitutes the positioning of the planetary carrier. This ensures that the first processed planetary carrier 11 will not have radial displacement during the processing, such as milling the planetary shaft hole, thus guaranteeing the positional and coaxiality accuracy of the planetary shaft hole.

[0044] The fixed base 1 has a second planetary carrier insertion hole 16 inside, and a second machining planetary carrier 17 is provided inside the second planetary carrier insertion hole 16. The diameter of the second planetary carrier insertion hole 16 is adapted to the outer diameter of the second machining planetary carrier 17, and is used to radially position the second machining planetary carrier 17. The second machining planetary carrier 17 is used as a blank to be processed in a high-precision planetary reducer. The outer diameter of the second machining planetary carrier 17 is different from the outer diameter of the first machining planetary carrier 11.

[0045] The second planetary carrier insertion hole 16 has a different diameter than the first planetary carrier insertion hole 10, which allows for the processing of planetary carriers of different specifications at the front and rear workstations. Since the diameter of the second planetary carrier insertion hole 16 is different from that of the first planetary carrier insertion hole 10, it can be adapted to two specifications: the first planetary carrier 11 and the second planetary carrier 17. At the same time, the handles 204 of the front and rear moving components 2 adopt a staggered layout. When rotating the handles 204, it is only necessary to rotate them in the direction closest to the operator. The handles 204 set at the front and rear will not collide. The first planetary carrier insertion hole 10 and the second planetary carrier insertion hole 16 on the fixed base 1 are suitable for high-precision planetary carriers with a module of 0.5-3mm, a number of teeth of 6-20, and a shaft hole position accuracy requirement of ≤0.008mm.

[0046] A second fixing post 14 is fixedly connected to the lower surface of the fixing base 1, and a fixing plate 15 is fixedly connected to the lower surface of the second fixing post 14.

[0047] The fixed base 1, the second fixed column 14, and the fixed plate 15 constitute the equipment installation support structure. The fixed plate 15 is made of high-strength cast iron HT300. The contact surface between the fixed plate 15 and the machining center bed is precision ground, with a flatness ≤0.002mm / m and a roughness Ra≤0.4μm. The fixed plate 15 is provided with multiple evenly distributed high-precision mounting holes, with a hole diameter tolerance of H7 grade and a hole position tolerance of ±0.003mm. It is connected to the machining center bed by high-strength precision bolts. When tightening the bolts, a torque wrench must be used to tighten them symmetrically to a preset torque to avoid deformation of the fixed plate 15. The second fixed column 14 is made of 40CrNiMoA alloy steel and is connected to the fixed seat 1 and the fixed plate 15 by welding. This ensures that the perpendicularity between the axis of the second fixed column 14 and the upper surface of the fixed seat 1 is ≤0.0015mm / 100mm, and the height difference between multiple second fixed columns 14 is ≤0.002mm. This connection structure ensures that the overall amplitude of the fixed seat 1 is ≤0.001mm when the machining center rotates, avoiding vibration from affecting the high-precision machining of the planetary carrier. At the same time, it ensures the parallelism between the worktable and the guide rail of the machining center, ensuring the accuracy of the feed motion.

[0048] Working principle: In use, multiple sets of first processing planetary carriers 11 or second processing planetary carriers 17 to be processed are placed in the first planetary carrier insertion hole 10 or the second planetary carrier insertion hole 16. Pushing the right end lifting part 13 of the connecting plate 12 upward causes multiple sets of positioning pressure plates 6 to move upward in the slide groove 5. At the same time, the positioning pressure plates 6 enter between the first processing planetary carriers 11 or second processing planetary carriers 17 to limit the first processing planetary carriers 11 or second processing planetary carriers 17. Turning the handle 204 causes the rotating shaft 201, rotating disk 205, and first fixed column 208 to rotate. The first fixed column 208 moves in the first guide groove 207, causing the moving plate 206 to move along the direction of the positioning column 4. Then, the positioning block 209 moves into the slide groove 5 below the positioning pressure plate 6. Releasing one end of the lifting part 13 allows for quick positioning of multiple sets of positioning pressure plates 6 without the need for repeated positioning one set at a time.

[0049] By installing the positioning bolt 9 in the internal threaded column 8, the positioning bolt 9 and the positioning pressure plate 6 are tightly fitted to limit the positioning pressure plate 6, thereby limiting the first processing planetary carrier 11 or the second processing planetary carrier 17. After the positioning block 209 is fully inserted into the slide groove 5, the locking column 203 enters the locking groove 20 and is locked in place. During the processing of the first processing planetary carrier 11 or the second processing planetary carrier 17, the workpiece is radially limited by the first planetary carrier insertion hole 10 or the second planetary carrier insertion hole 16, the positioning pressure plate 6 and the positioning bolt 9, and the workpiece is axially limited by the positioning block 209 to prevent the positioning bolt 9 from loosening and causing the workpiece to shift position. During operation, the handle 204 can only be rotated back and forth on the side closest to the operator. The handles 204 set at the front and rear will not collide during use.
