Detailed implementation manners

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0034] Referring to the attached Figures 1-10 , an electric vehicle front fork part production device includes a carrier for carrying the fork bone and the sleeve. The carrier includes a first carrier 10 and a second carrier 20 spaced apart. The first carrier 10 is used for carrying the fork bone, and the second carrier 20 is used for carrying the sleeve. The space between the two carriers facilitates the circular welding of the fork bone and the sleeve by the welding head.

[0035] A pair of limit frames 3 are provided on the bearing platform, and a limit frame 3 is provided on the first bearing platform 10 and the second bearing platform 20 respectively, each limit frame 3 includes bosses extending to both sides of the bearing platform, and the height of the bosses is higher than the top of the bearing platform, one side of the boss is rotatably connected to the limit rod 4, and the other side of the boss is provided with a positioning groove for accommodating the limit rod 4, which is used to fix the other end of the limit rod 4, and one side of the positioning groove passes through the limit frame 3, and the positioning groove includes a card slot 51 adapted to the limit rod 4, and the card slot 51 passes through one end of the limit frame 3 and is provided with a downwardly inclined slope 52, so that the limit rod 4 can rotate into the card slot 51, and a protrusion 53 is provided on the top wall of the card slot 51 to limit the limit rod 4 that rotates into the card slot 51. When in use, the fork bone and the sleeve are placed on the first bearing platform 1 respectively. 0 and the top of the second bearing platform 20, and then align the end of the sleeve with the welding position of the fork bone, and then rotate the two limiting rods 4 respectively, so that the two limiting rods 4 enter the slot 51 through the slope 52, and under the action of the protrusion 53, the top wall of the slot 51 will first elastically tilt upward, and then when the limiting rod 4 passes over the protrusion 53, the top wall of the slot 51 will elastically reset, so that the protrusion 53 limits the limiting rod 4. At this time, the bottoms of the two limiting rods 4 will respectively abut against the top of the fork bone and the sleeve, so that the fork bone and the sleeve are respectively fixed to the first bearing platform 10 and the second bearing platform 20. When disassembling, the two limiting rods 4 are rotated in the opposite direction to quickly remove the welded front fork component, which significantly enhances the convenience of fixing and disassembly, greatly shortens the operation time, and effectively improves the overall production efficiency.

[0036] In this embodiment, the limit frame 3 is of a U-shaped structure, which is vertically slidably connected to the bearing platform. Two first motors 61 are arranged on the bearing platform. Cams 62 are arranged on the output shafts of the two first motors 61. Each cam 62 is slidably connected to the bottom of the limit frame 3. A strip groove matching the cam 62 is provided at the bottom of the limit frame 3 to achieve stable lifting and lowering of the limit frame 3. A first spring 63 is provided between the limit frame 3 and the bearing platform to facilitate the stability of the position of the limit frame 3. The two first motors 61 are started. At this time, the two cams 62 rotate and lift up the limit frames 3 respectively. At this time, the distance between the limit rods 4 on the two limit frames 3 and the top of the bearing platform will change, which is convenient for fixing forks and sleeves of different sizes.

[0037] In this embodiment, a plurality of V-shaped bearing blocks 71 are provided on the bearing platform. The V-shaped bearing blocks 71 on the first bearing platform 10 are arranged in pairs, and the V-shaped bearing blocks 71 on the second bearing platform 20 are arranged in a straight line. The fork bone is placed on the V-shaped bearing block 71 on the first bearing platform 10, and the sleeve is placed on the V-shaped bearing block 71 on the second bearing platform 20. By providing the V-shaped bearing block 71 to support the bottom of the fork bone and the sleeve, the fixing force of the limit rod 4 on the fork bone and the sleeve can be improved.

[0038] In this embodiment, a slider 72 is provided at the bottom of the V-shaped bearing block 71 on the first bearing platform 10, and a plurality of slide grooves 73 are opened on the first bearing platform 10 for the sliders 72 arranged in pairs to slide. A screw rod 74 is rotatably connected in each slide groove 73, and each screw rod 74 passes through the sliders 72 arranged in pairs and forms a threaded connection therewith, and a knob 75 is provided at the end of each screw rod 74. When the knob 75 is turned, the screw rod 74 rotates to make the sliders 72 arranged in pairs on the first bearing platform 10 move toward or oppositely, and further makes the V-shaped bearing blocks 71 arranged in pairs move toward or oppositely, which can flexibly adapt to and fix fork bones of different sizes and models, significantly improving the versatility of the device. Compared with the traditional method in which each fork bone needs to be equipped with a specific type of fixing clamp, its applicability is greatly enhanced.

[0039] A pair of positioning posts 101 are provided on the first bearing platform 10 to abut against the side of the forkbone away from the sleeve, and a pushing unit is provided on the second bearing platform 20 to push the sleeve toward the forkbone. When the forkbone is placed on the first bearing platform 10, a pair of positioning posts 101 abut against the side of the forkbone away from the sleeve, and then the sleeve is pushed by the pushing unit so that the end of the sleeve is tightly attached to the forkbone, thereby avoiding displacement of the sleeve during welding and affecting the welding quality.

[0040] The pushing unit includes a push plate 81, and two connecting rods 82 are provided at the front end of the push plate 81. The ends of the two connecting rods 82 away from the push plate 81 are respectively rotatably connected with clamping arms 83, which can drive the clamping arms 83 on both sides to move forward and backward. One end of the clamping arm 83 is inserted into a limit frame 84, and the limit frame 84 is inclined so that the two clamping arms 83 are close to each other when extending forward. Each clamping arm 83 is sleeved with a clamping sleeve 85, and the two ends of the second spring 86 in the clamping sleeve 85 are respectively connected to the clamping sleeve 85 and the clamping arm 83, and each clamping sleeve 85 is provided at the top The clamping rod 87 for clamping the sleeve pushes the push plate 81, and at this time, the two connecting rods 82 drive the clamping arms 83 on both sides to extend forward and approach each other, and further drive the clamping sleeves 85 on both sides to extend forward and approach each other through the second spring 86. At this time, the clamping rod 87 extends forward and approaches each other to push and clamp the sleeve, so that the sleeve and the fork bone are tightly fitted, and there is a gap between the clamping sleeve 85 and the clamping arm 83. The second spring 86 is installed in the gap, which can effectively prevent the clamping rod 87 from clamping the sleeve too tightly when extending forward, causing damage to the sleeve, thereby ensuring the integrity of the sleeve.

[0041] Furthermore, a track groove 88 for the sliding of the push plate 81 is formed in the top of the second bearing platform 20. A third spring 89 connected to the push plate 81 is arranged in the track groove 88. A vertical rod is arranged on the top of the push plate 81, and the height of the vertical rod is higher than that of the limiting rod 4 on the first bearing platform 10, so that when the limiting rod 4 rotates into the clamping groove 51, the push plate 81 can be pushed forward. When the limiting rod 4 rotates into the clamping groove 51 to fix the sleeve, the vertical rod on the push plate 81 will be pushed, so that the push plate 81 moves forward along the track groove 88, and further makes the clamping rods 87 extend forward and approach each other to push and clamp the sleeve. This process does not require additional driving, significantly improving the convenience of the clamping operation and simplifying the operation process.

[0042] The bottoms of the first bearing platform 10 and the second bearing platform 20 are jointly connected with a support plate 30. A first rotating shaft 311 is arranged at the bottom of the support plate 30. A connecting block 312 is arranged at the bottom of the first rotating shaft 311. Second rotating shafts 313 are arranged on both sides of the connecting block 312. The two second rotating shafts 313 jointly rotatably connect a U-shaped plate 314. The bottom of the U-shaped plate 314 is connected to the output shaft of the second motor 315, and the axis of the output shaft of the second motor 315 is collinear with the axis of the first rotating shaft 311. When the second motor 315 is started, at this time, the U-shaped plate 314 drives the connecting block 312 to rotate through the second rotating shafts 313, and further makes the first rotating shaft 311 drive the support plate 30 to rotate in the horizontal direction. At this time, the fork bones and sleeves on the fixed bearing platform can also rotate in the horizontal direction, facilitating the welding head to weld different positions of the fork bones and sleeves.

[0043] In this embodiment, a socket plate 321 is sleeved on the outer wall of the first rotating shaft 311. One side of the socket plate 321 is connected to the output shaft of the third motor 322, and the axis of the output shaft of the third motor 322 is collinear with the axes of the two second rotating shafts 313. When the third motor 322 is started, at this time, the socket plate 321 drives the first rotating shaft 311 to rotate, and further makes the support plate 30 drive the bearing platform to rotate in the vertical direction, facilitating the circumferential welding of the fork bones and sleeves.
