Description

Technical Field

[0001] This invention relates to the field of locomotive parts processing technology, specifically to a locomotive parts processing device. Background Technology

[0002] The motorcycle's lower coupling plate is a core steering and load-bearing component connecting the steering column, front fork, and frame. Modern motorcycles typically have three key holes arranged in a triangular pattern on the lower coupling plate, such as... Figure 11 The three key holes are a complete hole 51 in the center of the lower connecting plate 5 and two symmetrical slotted holes 52. The complete hole 51 is used to install the steering column, providing the steering axis and vertical load. The slotted hole 52 is not a complete circular hole, but has a side groove cut on one side. This structure allows the hole wall to produce controlled elastic contraction by tightening the bolt, thereby fixing the fork with radial clamping force and ensuring handling rigidity.

[0003] Currently, the side grooves on the slotted side of the lower connecting plate are mostly processed by a cutting device. Since the two slotted holes are symmetrically distributed on both sides of the lower connecting plate, the existing cutting device can only cut the side groove on one slotted side first. When it is necessary to cut the side groove on the other slotted side, the lower connecting plate needs to be removed from the cutting device and reinstalled. This process is inefficient and inconvenient. Therefore, the applicant has developed a new technical solution in actual production to solve the above-mentioned technical problems. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the present invention aims to provide a locomotive parts processing device that has the advantage of being able to cut side grooves on one side of the two slotted holes of the lower connecting plate without having to remove and reinstall it.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention provides a locomotive parts processing apparatus, comprising: A cutting mechanism, which includes a cutting saw blade; The mounting box has a rotatable turntable inside, and the turntable is equipped with a mounting mechanism for mounting the lower connecting plate; A rotating mechanism, mounted on the mounting box, is used to drive the turntable to rotate. The lifting mechanism is used to move the mounting box vertically. Cooling mechanism, used to cool the cutting saw blade; The cutting saw blade is located inside the mounting box and below the lower connecting plate, and corresponds vertically to a slotted hole on the lower connecting plate. When the lifting mechanism pushes the mounting box downwards, the cutting saw blade cuts a side groove on the corresponding slotted hole side. Then, when the cutting saw blade is above the lower connecting plate, the rotating mechanism drives the turntable to rotate, so that the cutting saw blade corresponds to another slotted hole side on the lower connecting plate. The lifting mechanism then pushes the mounting box upwards, and the cutting saw blade cuts a side groove on the other slotted hole side.

[0006] By adopting the above technical solution, during use, the lower connecting plate is installed on the turntable via the mounting mechanism. At this time, the cutting saw blade is located below the lower connecting plate and corresponds vertically to one side of the slotted hole on the lower connecting plate. Then, the mounting box is moved down by the lifting mechanism. At this time, the cutting saw blade of the cutting mechanism will cut a side groove on the corresponding slotted hole side. After the cutting is completed, the cutting saw blade is located above the lower connecting plate. At this time, the rotating mechanism drives the turntable to rotate, and the turntable drives the lower connecting plate to rotate along the rotation axis of the turntable until the cutting saw blade corresponds to another slotted hole side on the lower connecting plate. Then, the lifting mechanism pushes the mounting box upward, and the cutting saw blade cuts a side groove on the other slotted hole side. Finally, the lower connecting plate is removed and the next lower connecting plate to be cut is installed. The above process realizes a processing flow of one clamping and two cuttings, avoiding the repeated disassembly and installation of the lower connecting plate, significantly improving processing efficiency, and improving the symmetry and processing accuracy of the two slotted hole side grooves.

The positioning post has an opening groove that mates with the cutting saw blade; The insert is equipped with a fixing mechanism for fixing the lower connecting plate to the support column; After the lower connecting plate is installed, one of the slotted holes on one side corresponds vertically to the cutting saw blade, and the upright below the slotted hole is parallel to the cutting saw blade. When the lower connecting plate moves vertically, the cutting saw blade cuts a side groove on the slotted hole side and passes through the opening groove on the positioning post.

[0010] Preferably, the limiting mechanism includes a baffle and two baffle posts. The baffle is horizontally arranged on the wall of the communicating groove, and the two baffle posts are located inside the communicating groove and are both vertically arranged at the bottom of the turntable, with the two baffle posts respectively located close to the two uprights. When one side of one of the uprights is parallel to the cutting saw blade, the stop below it contacts the baffle. When the turntable rotates, so that the cutting saw blade corresponds to another slotted side of the lower connecting plate, one side of the other upright is parallel to the cutting saw blade, and the stop below it contacts the baffle, thereby limiting the rotation angle of the turntable.

[0011] Preferably, the fixing mechanism includes a cylinder and a circular hole at the top of the cylinder. A positioning shaft is coaxially provided at the bottom of the circular hole.

The cylinder has several arc-shaped second protrusions on its arc-shaped wall, and each second protrusion is evenly distributed along the length direction of the cylinder. The diameter of the circular hole is larger than the diameter of the cylinder. During installation, insert the cylinder into the round hole and press the rotary disc downwards so that the bottom end of the rotary disc presses the lower connecting plate tightly onto the support column. Then rotate the rotary disc so that the second protrusion engages between two adjacent first protrusions. The cylinder and the rotary disc are locked together by the cooperation of the first and second protrusions, thereby fixing the lower connecting plate onto the support column.

[0020] The technical solutions of 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.

[0021] A locomotive parts processing device, such as Figure 1 and Figure 2 ,include: A cutting mechanism, which includes a cutting saw blade 45; The mounting box 1 has a rotatable turntable 12 inside, and the turntable 12 has a mounting mechanism for mounting the lower connecting plate 5. A rotating mechanism, mounted on mounting box 1, is used to drive the turntable 12 to rotate. The lifting mechanism is used to drive the mounting box 1 to move vertically; A cooling mechanism is used to cool the cutting saw blade 45; The cutting saw blade 45 is located inside the mounting box 1 and below the lower connecting plate 5, and corresponds vertically to one side of a slotted hole 52 on the lower connecting plate 5. When the lifting mechanism pushes the mounting box 1 downward, the cutting saw blade 45 cuts a side groove on the corresponding side of the slotted hole 52. Then, the cutting saw blade 45 is located above the lower connecting plate 5. At this time, the rotating mechanism drives the turntable 12 to rotate, so that the cutting saw blade 45 corresponds to another side of the slotted hole 52 on the lower connecting plate 5. The lifting mechanism then pushes the mounting box 1 upward, and the cutting saw blade 45 cuts a side groove on the other side of the slotted hole 52.

[0022] like Figure 1 and Figure 2 In use, the lower connecting plate 5 is installed on the turntable 12 via the mounting mechanism. At this time, the cutting saw blade 45 is located below the lower connecting plate 5 and corresponds vertically to one side of a slotted hole 52 on the lower connecting plate 5. Then, the mounting box 1 is moved down by the lifting mechanism. At this time, the cutting saw blade 45 of the cutting mechanism will cut a side groove on the corresponding side of the slotted hole 52. After the cutting is completed, the cutting saw blade 45 is located above the lower connecting plate 5. At this time, the rotating mechanism drives the turntable 12 to rotate. The turntable 12 drives the lower connecting plate 5 to rotate along the rotation axis of the turntable 12 until the cutting saw blade 45 corresponds to another side of the slotted hole 52 on the lower connecting plate 5. Then, the lifting mechanism pushes the mounting box 1 to move upward, and the cutting saw blade 45 cuts a side groove on the other side of the slotted hole 52. Finally, the lower connecting plate 5 is removed and the next lower connecting plate 5 to be cut is installed. The above process realizes a processing flow of one clamping and two cuttings, avoiding repeated disassembly and installation of the lower connecting plate 5, significantly improving processing efficiency, and improving the symmetry and processing accuracy of the two slotted holes 52 side grooves.

[0023] like Figure 2 and Figure 3The rotating mechanism includes a ring 13 located at the bottom of the mounting box 1. A turntable 12 is coaxially rotatably connected to the top of the ring 13. A connecting groove 14 communicating with the ring 13 is provided at the bottom of the mounting box 1. A support frame 15 is provided at the bottom of the mounting box 1, and a power source 151 for driving the turntable 12 to rotate is provided on the support frame 15. A limiting mechanism is provided on the mounting box 1 to limit the rotation angle of the turntable 12. The power source 151 can be a servo motor, or a gear, rack, and cylinder. When the power source 151 is a gear (not shown in the figure), a rack (not shown in the figure), or a cylinder (not shown in the figure), the rotation... The bottom end of the disc 12 is coaxially provided with a central shaft (not shown in the figure), a gear is set at the bottom end of the central shaft, a cylinder is set on the support frame 15, and a rack is horizontally set at one end of the piston rod of the cylinder and meshes with the gear. The rotating mechanism drives the disc 12 to rotate on the ring 13 through the power source 151. The connecting groove 14 facilitates power transmission. The limiting mechanism can control the rotation angle of the disc 12 to ensure that the two slotted holes 52 can be aligned with the cutting saw blade 45, avoiding over-rotation or under-rotation, improving positioning accuracy and operational safety. The disc 12 is supported by the ring 13, which reduces the occurrence of coolant leakage from the connecting groove 14.

[0024] like Figures 1-3 The lifting mechanism includes a base plate 2 and an electric cylinder 21 mounted on the base plate 2. The base plate 2 has four columns 22, which are evenly distributed around the circumference of the mounting box 1. Each column 22 is vertically slidably connected to a sliding plate 221, which is fixedly connected to the outer wall of the mounting box 1. One end of the piston rod of the electric cylinder 21 is connected to the bottom end of the support frame 15. The electric cylinder 21 pushes the support frame 15 up and down through the piston rod, thereby driving the mounting box 1 to rise and fall smoothly along the columns 22. The structure of the four columns 22 and the sliding plate 221 provides uniform support, reduces the tilting of the mounting box 1 during the lifting process, improves cutting stability, and ensures good consistency in the edge groove processing. The tops of the four columns 22 are connected by a rectangular frame 222. Connecting the four columns 22 together through the rectangular frame 222 can improve strength and reduce the shaking of the columns 22, thereby improving the stability of the sliding plate 221 moving on the columns 22.

[0025] like Figures 2-5 The installation mechanism includes a support column 121 and two semi-circular uprights 122 located at the top of the turntable 12. The support column 121 is coaxial with the turntable 12 and has an insertion post 1211 at its top for inserting into the central hole 51 of the lower connecting plate 5. Each of the two uprights 122 has a positioning post 1221 for inserting into the two slotted holes 52 of the lower connecting plate 5, and the top of the positioning post 1221 extends out of the slotted hole 52. The positioning post 1221 has an opening slot 1222 that mates with the cutting saw blade 45. The insertion post 1211 has a fixing mechanism for fixing the lower connecting plate 5 to the support column 121. After the lower connecting plate 5 is installed, one side of the slotted hole 52 corresponds vertically to the cutting saw blade 45, and one side of the upright 122 below the slotted hole 52 is parallel to the cutting saw blade 45. When the lower connecting plate 5 moves vertically, the cutting saw blade 45 cuts a side groove on one side of the slotted hole 52 and passes through the opening slot 1222 on the positioning post 1221. The installation mechanism achieves rapid positioning of the lower connecting plate 5 through the insertion post 1211 and the positioning post 1221. The fixing mechanism fixes the lower connecting plate 5 to the support post 121 to achieve fixed positioning. The opening slot 1222 is for cutting. The saw blade 45 provides a cutting channel to avoid interference with the positioning post 1221. The upright post 122 is set in a semi-circle to avoid interference between the cutting saw blade 45 and the upright post 122. The above structure ensures that the lower connecting plate 5 is fixed in position during the cutting process and the edge groove is accurately machined, which is suitable for mass production. During the cutting process, the opening groove 1222 on the positioning post 1221 can block the cutting waste chips, reduce their flying around, and improve the safety of use. At the same time, the positioning post 1221 can reduce the occurrence of waste chips adhering to the inner wall of the slotted hole 52.

[0026] like Figure 3 The limiting mechanism includes a baffle 141 and two stop posts 123. The baffle 141 is horizontally mounted on the wall of the connecting groove 14. The two stop posts 123 are located inside the connecting groove 14 and are vertically mounted at the bottom of the turntable 12. The two stop posts 123 are respectively positioned close to the two uprights 122. When one side of one upright 122 is parallel to the cutting saw blade 45, the stop post 123 below it contacts the baffle 141. When the turntable 12 rotates, so that the cutting saw blade 45 corresponds to the other side of the slotted hole 52 on the lower connecting plate 5, one side of the other upright 122 is parallel to the cutting saw blade 45, and the stop post 123 below it contacts the baffle 141, thereby limiting the rotation angle of the turntable 12. The stop posts 123 and the baffle 141 cooperate to achieve mechanical angle limiting. The structure is simple and reliable. When the turntable 12 rotates to the predetermined position, it automatically blocks, ensuring that the cutting saw blade 45 can accurately align with the other side of the slotted hole 52 after each rotation, thus improving processing accuracy.

[0027] like Figures 3-9The fixing mechanism includes a cylinder 1214 and a circular hole 1212 disposed at the top of the insertion post 1211. A positioning shaft 1213 is coaxially disposed at the bottom of the circular hole 1212. The cylinder 1214 is vertically inserted into the circular hole 1212, and the bottom end of the cylinder 1214 is provided with a circular groove 1215 for the positioning shaft 1213 to be vertically inserted. A rotating disk 1216 is coaxially disposed at the top end of the cylinder 1214. A plurality of arc-shaped first protrusions 1217 are provided on one side of the hole wall of the circular hole 1212, and each of the first protrusions 1217 is evenly distributed along the depth direction of the circular hole 1212. A plurality of arc-shaped second protrusions 1218 are provided on the arc-shaped wall of the cylinder 1214, and each of the second protrusions 1218 is evenly distributed along the length direction of the cylinder 1214. The diameter of the circular hole 1212 is larger than the diameter of the cylinder 1214. During installation, insert the cylinder 1214 into the circular hole 1212 and press down on the rotary disc 1216, so that the bottom end of the rotary disc 1216 presses the lower connecting plate 5 onto the support column 121. Then rotate the rotary disc 1216 so that the second protrusion 1218 engages between two adjacent first protrusions 1217. The cylinder 1214 and the rotary disc 1216 are locked by the cooperation of the first protrusions 1217 and the second protrusions 1218, thereby fixing the lower connecting plate 5 onto the support column 121. The fixing mechanism adopts a protrusion interlocking structure. By pressing down and rotating the rotary disc 1216, quick locking and releasing can be achieved. The clamping is firm and the operation is simple. The positioning shaft 1213 and the circular groove 1215 cooperate to improve the assembly alignment accuracy. It is suitable for production scenarios with frequent assembly and disassembly, and at the same time reduces the possibility of the cylinder 1214 shifting in the circular hole 1212, which may cause locking failure.

[0028] like Figure 8 The cutting mechanism also includes a housing 4 and a cutting motor 41 installed inside the housing 4. The housing 4 is equipped with a drive shaft 42 for driving the cutting saw blade 45 to rotate. The cutting motor 41 is connected to the drive shaft 42. The mounting box 1 has a notch 16. The end of the drive shaft 42 away from the housing 4 passes through the notch 16 and is connected to the cutting saw blade 45. When the mounting box 1 moves vertically downward, the drive shaft 42 moves vertically out along the notch 16. The housing 4 is placed on the ground on one side of the lifting mechanism. The cutting motor 41 drives the saw blade to rotate through the drive shaft 42. The notch 16 allows the mounting box 1 to move relative to the drive shaft 42 during lifting and lowering, so that the saw blade can complete the up and down cutting action while rotating in a fixed position. The structure is compact and the transmission is stable.

[0029] like Figure 1 and Figure 2The cooling mechanism includes a filter box 3 for storing coolant, a circulation system, and two nozzles 341. The circulation system connects the filter box 3, the mounting box 1, and the two nozzles 341. One nozzle 341 is located above the cutting saw blade 45 and tilted downwards towards the cutting saw blade 45, while the other nozzle 341 is located below the cutting saw blade 45 and tilted upwards towards the cutting saw blade 45. When the mounting box 1 moves vertically and the cutting saw blade 45 cuts the corresponding side with the slotted hole 52, the coolant sprayed from the nozzles 341 is used to cool and lubricate the cutting saw blade 45. The dual nozzles 341 spray coolant onto the saw blade from both the top and bottom, effectively reducing the cutting temperature, reducing wear, and extending the saw blade's life. At the same time, the lubrication effect can improve the quality of the cutting surface and reduce burr generation.

[0030] like Figure 10 The circulation system includes a return pipe 31, located at the bottom of the mounting box 1, with one end connected to the upper side of the filter box 3. The return pipe 31 is a flexible hose. A pumping pipe 32 is vertically installed inside the filter box 3 via a fixing bracket 33, and a pumping pump 321 is mounted on it. Two L-shaped branch pipes 34 are connected to the upper side of the pumping pipe 32. Two nozzles 341 are respectively mounted on the two branch pipes 34. One end of each branch pipe 34 with a nozzle 341 extends into the mounting box 1 through a notch 16. A filter plate 35 is vertically mounted inside the filter box 3, located between the pumping pipe 32 and the return pipe 31. Coolant is recovered to the filter box 3 through the return pipe 31, filtered by the filter plate 35, and then pumped back to the nozzles 341 by the pumping pump 321 through the pumping pipe 32 and the two branch pipes 34, achieving recycling and saving coolant costs. The filter plate 35 can remove impurities such as metal shavings, keep the coolant clean, and improve system stability.

[0031] like Figure 1 The filter box 3 is detachably connected to a cover plate 36 for sealing the opening of the filter box 3. The cover plate 36 is easy to open and clean the filter plate 35 and the filter box 3, making maintenance convenient and ensuring the long-term effective operation of the cooling system.

[0032] The working process of this device is as follows: Step 1: Installing and positioning the workpiece Align the complete hole 51 in the center of the lower connecting plate 5 with the insert 1211 at the top of the support column 121, and align the slotted holes 52 on both sides of the lower connecting plate 5 with the positioning posts 1221 of the two uprights 122 respectively. At this time, the side to be cut of one of the slotted holes 52 is aligned vertically with the cutting saw blade 45 below. Then, through the fixing mechanism (insert the cylinder 1214 into the round hole 1212 of the insert 1211, at which time the positioning shaft 1213 enters the round groove 1215, and then press down and rotate the rotary table 1216), the interlocking of the first protrusion 1217 and the second protrusion 1218 firmly presses the lower connecting plate 5 onto the support column 121, completing the quick clamping and precise positioning of the workpiece.

[0033] Step 2: Perform the first cut (downward cut). Start the cutting motor 41 to drive the cutting saw blade 45 to rotate. At the same time, start the water pump 321 of the cooling mechanism to spray coolant from the upper and lower nozzles 341 to pre-cool and lubricate the saw blade. Control the electric cylinder 21 of the lifting mechanism so that its piston rod pushes the support frame 15 and the entire mounting box 1 to descend smoothly along the four columns 22. As the mounting box 1 moves down, the rotating cutting saw blade 45 passes upward through the opening slot 1222 on the positioning column 1221 and cuts one side of the first slotted hole 52 that has been aligned, forming the first side slot. The heat generated by cutting is suppressed by the continuously sprayed coolant.

[0034] Step 3: Rotate the workpiece to switch work stations Safe separation: After the first downward cut is completed, the cutting saw blade 45 is located above the lower connecting plate 5, and the lower connecting plate 5 is completely separated from the rotating saw blade in the vertical direction.

[0035] Drive rotation: After confirming that the saw blade is safely separated from the workpiece, start the power source 151 of the rotation mechanism to drive the turntable 12 and the lower connecting plate 5 that is fixed on it to rotate together around the axis of the turntable 12.

[0036] Precise positioning and stopping: The two stop posts 123 at the bottom of the turntable 12 rotate together with it. Their movement trajectory is as follows: the stop post 123 that was originally in contact with the baffle 141 (corresponding to the first processing station) separates from the baffle 141 as the turntable 12 rotates; at the same time, the other stop post 123 rotates to contact the same baffle 141. When the stop post 123 contacts the baffle 141, the rotation action automatically stops.

[0037] Switching complete: At this time, the turntable 12 has rotated exactly to the predetermined angle, so that the other side of the lower connecting plate 5 with the slot 52 to be cut is aligned with the cutting saw blade 45 in the fixed position in the vertical direction, thereby completing the automatic and precise switching between the two processing stations.

[0038] Step 4: Perform the second cut (upward cut). Keep the cutting motor 41 and cooling system running continuously, control the electric cylinder 21 of the lifting mechanism so that its piston rod pushes the support frame 15 and the mounting box 1 to rise smoothly along the column 22. As the mounting box 1 rises, the rotating cutting saw blade 45 cuts one side of the second aligned slotted hole 52 to form the second side groove. During this process, the coolant continuously cools and lubricates the saw blade to ensure the cutting quality.

[0039] Step 5: Remove the finished product and put it back in its original position. After the second cut is completed, the electric cylinder 21 drives the mounting box 1 back to a height that is easy to operate, releases the fixing mechanism (reverses and lifts the turntable 1216), and removes the processed lower connecting plate 5 from the mounting mechanism. At this time, all mechanisms of the device are reset, ready for the processing of the next workpiece. Meanwhile, the coolant returns to the filter box 3 through the return hose at the bottom of the mounting box 1. After being filtered by the filter plate 35, the coolant can be reused by the circulation pump.

[0040] In summary, the entire process, through a continuous flow of "one-time clamping → cutting the first groove downwards → automatic rotation switching → cutting the second groove upwards → unloading," achieves efficient and precise processing of the two side grooves of the lower connecting plate 5, avoiding the problem of repeated disassembly and assembly of workpieces in traditional processes, and significantly improving production efficiency and processing consistency.
