Description

Technical Field

[0001] The present invention relates to the field of charging pile processing equipment, and in particular to a welding and grinding integrated processing equipment for charging piles. Background Art

[0002] After the shell of the charging pile is assembled, the connection gap of the shell needs to be annularly welded to ensure the connection stability and sealing between the shells. After welding, the welding point needs to be polished to eliminate stress to improve the stability of the charging pile, beautify the welding position and improve product competitiveness.

[0003] In the traditional processing and production of charging pile shells, welding and grinding are carried out by different equipment. Between the two processing steps, the charging pile products need to be moved to achieve sequential processing. The charging pile is heavy, and the two moves result in a large workload for the processing of the charging pile. In addition, the charging pile needs to be repeatedly positioned, which requires high positioning accuracy and has a certain impact on the accuracy of the grinding process.

[0004] Therefore, manufacturers generally fix the charging pile products through specific fixtures, and use turntable equipment to drive the charging pile products and fixtures to move, avoiding repeated positioning. In order to achieve circular welding and grinding, the welding head and grinding head need to rotate relative to the charging pile product, so the product fixture also needs to rotate relative to the turntable equipment. The turntable equipment in the prior art is equipped with drive elements such as motors for driving the fixture on the turntable, resulting in high costs and complex control. In particular, when the product needs to undergo multiple welding and grinding, the turntable equipment needs to set up multiple workstations, the number of drive elements is large, and the equipment cost is very high. Summary of the invention

[0005] The purpose of the present invention is to provide a welding and grinding integrated processing equipment for charging piles to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0006] The technical solutions adopted to solve the above technical problems are:

The rotating drive unit drives multiple positioning fixtures to rotate relative to the rotating disk at the same time through the driving disk and the transmission roller, thereby cooperating with the feeding action of the laser welding head and the grinding component to realize the annular path welding processing and grinding treatment of the outer periphery of the charging pile. The rotating disk can drive multiple positioning fixtures to rotate, so that each positioning fixture can be transferred along a fixed route to realize the sequential welding and grinding treatment. When the driving disk rotates, the corresponding positioning fixture can be driven to rotate through the transmission roller.

The integrated welding and grinding processing equipment of the present invention realizes the welding and grinding of the charging pile through the rotatable positioning fixture in cooperation with the welding mechanism and the grinding mechanism. The charging pile that has completed welding can be transferred from the side of the welding mechanism to the side of the grinding mechanism through the rotating disk, and the welding and grinding processes are realized in turn.

[0040] Reference Figures 1 to 10 The welding and grinding integrated processing equipment for charging piles of the present invention is implemented as follows:

[0041] A welding and grinding integrated processing device for a charging pile includes: a turntable device 10 and a processing device 20.

[0042] like Figure 1 As shown, the turntable device 10 includes: a turntable mechanism 200 and a plurality of positioning fixtures 230 .

[0043] The turntable mechanism 200 includes: a rotating disk 210 and a turntable driving component 220. The rotating disk 210 has a rotation axis extending up and down. The turntable driving component 220 is used to drive the rotating disk 210 to rotate around its rotation axis. A plurality of positioning jigs 230 are evenly distributed around the circumference of the rotation axis of the rotating disk 210. The positioning jig 230 is used to fix the charging pile. The positioning jig 230 is rotatably connected to the rotating disk 210, and the rotating disk 210 is provided with a rotation driving component 300. The rotation driving component 300 is used to drive the positioning jig 230 to rotate relative to the rotating disk 210.

[0044] Reference Figure 1 and Figure 2, the processing device 20 includes: a welding mechanism 500 and a grinding mechanism 600. The welding mechanism 500 and the grinding mechanism 600 are respectively arranged on the sides of two adjacent positioning fixtures 230. The welding mechanism 500 includes: a laser welding head 510 and a welding feed component 530. The welding feed component 530 is used to drive the laser welding head 510 to approach or move away from the corresponding positioning fixture 230. The grinding mechanism 600 includes a grinding component 610 and a grinding feed component 630. The grinding feed component 630 is used to drive the grinding component 610 to approach or move away from the corresponding positioning fixture 230.

[0045] In actual use, the charging pile to be processed is fixed on the positioning fixture 230. The welding feed member 530 can drive the laser welding head 510 to approach the corresponding positioning fixture 230, so as to weld the charging pile on the positioning fixture 230. The rotating drive member 300 drives the positioning fixture 230 to rotate, so as to cooperate with the laser welding head 510 to realize the annular path welding processing of the outer periphery of the charging pile. Similarly, the grinding feed member 630 can drive the grinding member 610 to approach the corresponding positioning fixture 230, and cooperate with the rotation of the positioning fixture 230 to realize the grinding treatment of the charging pile thereon. The turntable driving member 220 can drive the rotating disk 210 to rotate, so that multiple positioning fixtures 230 can rotate synchronously, so that the charging pile after the welding process is completed can be transferred to the side of the grinding mechanism 600. The welding and grinding integrated processing equipment realizes the welding and grinding of the charging pile through the rotatable positioning fixture 230 in cooperation with the welding mechanism 500 and the grinding mechanism 600. The charging pile that has completed welding can be moved from the side of the welding mechanism 500 to the side of the grinding mechanism 600 by the rotating disk 210, and the welding and grinding processes are performed in sequence.

[0046] The rotating disk 210 has a plurality of workstations distributed at equal intervals around the circumference, and the number of the positioning fixtures 230 is consistent with the number of the workstations. Two adjacent workstations are used as a loading station and an unloading station, and the remaining workstations correspond to the welding mechanism 500 or the grinding mechanism 600 one by one.

[0047] The number of the positioning jigs 230 and the number of the welding mechanisms 500 and the grinding mechanisms 600 can be set according to the number of parts of the charging pile that need to be welded. Figure 3 In the illustrated embodiment, when the number of the welding mechanism 500 and the number of the grinding mechanism 600 are both one, the number of the positioning fixtures 230 is four.

[0048] The turntable device 10 has loading stations, welding stations, grinding stations and unloading stations evenly distributed at equal intervals around the circumference of the rotating disk 210. The loading stations, welding stations, grinding stations and unloading stations are arranged in sequence along the rotation direction of the rotating disk 210. The welding mechanism 500 is arranged beside the welding station, and the grinding mechanism 600 is arranged beside the grinding station.

[0049] In actual use, the four positioning jigs 230 are respectively located at the loading station, welding station, grinding station and unloading station. The turntable driving component 220 drives the rotating disk 210 to rotate each time, so that the four positioning jigs 230 can reach the loading station, welding station, grinding station and unloading station in sequence.

[0050] First, the charging pile is placed on the corresponding positioning jig 230 at the loading station and fixed. Then, the charging pile moves to the welding station with the positioning jig 230, and the welding process is realized by the welding mechanism 500 cooperating with the rotation of the positioning jig 230. Next, the positioning jig 230 rotates to the grinding station with the rotating disk 210, and the grinding process is realized by the grinding mechanism 600 cooperating with the rotation of the positioning jig 230. Finally, the charging pile that has completed the two processes of welding and grinding moves to the unloading station with the positioning jig 230, and is taken away to realize unloading.

[0051] The loading and unloading actions of the charging pile at the loading and unloading stations can be achieved by existing loading and unloading equipment, which will not be described in detail here. In some embodiments, the number of the positioning fixtures 230 can be set to at least three, and the rotating disk 210 can be evenly set with the following three stations: welding station, grinding station and loading and unloading station. The loading and unloading actions of the charging pile are completed in the loading and unloading stations.

[0052] In some other embodiments, refer to the attached Fig. 9 and 10 When the charging pile needs to be welded and processed at two different parts, the number of the processing devices 20 is two, and the number of the workstations and positioning fixtures 230 is six. Two adjacent workstations are the loading station and the unloading station, and the remaining four workstations are two welding stations and two grinding stations. The two welding stations and the two grinding stations are arranged at intervals, so that the two processing devices 20 can be distributed around the circumference of the rotating disk 210, and are aligned with the corresponding positioning fixtures 230 on the welding station and the grinding station.

[0053] In this embodiment, the welding and grinding integrated processing equipment is provided with a base 100, and the turntable device 10 and the processing device 20 are both installed on the upper side of the base 100. The rotating disk 210 is rotatably connected to the base 100, and the turntable driving member 220 is fixedly installed on the base 100, and the turntable driving member 220 has a turntable driving end that is transmission-connected to the rotating disk 210 and causes the rotating disk 210 to rotate.

[0054] In order to adapt to the welding position requirements of charging piles of different specifications, the welding mechanism 500 and the grinding mechanism 600 are adjustable in the up and down direction. Specifically, the processing device 20 includes a lifting platform 410 and a lifting drive mechanism 420. The lifting platform 410 is slidably connected to the base 100 in the up and down direction. The welding mechanism 500 and the grinding mechanism 600 are both installed on the lifting platform 410. The lifting drive mechanism 420 is used to drive the lifting platform 410 to move up and down relative to the turntable device 10.

[0055] Reference Figure 4 and Figure 5 In this embodiment, the lifting drive mechanism 420 includes a lifting adjustment screw 421. The lifting adjustment screw 421 extends in the up and down direction and is rotatably connected to the base 100. The lifting platform 410 is threadedly connected to the lifting adjustment screw 421. When the lifting adjustment screw 421 is rotated, the lifting platform 410 can be lifted and lowered under the action of the threaded transmission, thereby adjusting the welding mechanism 500 and the grinding mechanism 600 up and down. The lifting adjustment screw 421 can be manually adjusted by a hand wheel or automatically adjusted by a motor. In some other embodiments, the lifting drive mechanism 420 can also use other linear drive components such as cylinders, electric push rods, hydraulic push rods, or screw nut drive assemblies.

[0056] In this embodiment, the welding mechanism 500 includes an adjustment seat 520. The laser welding head 510 is fixedly mounted on the adjustment seat 520. The adjustment seat 520 is slidably mounted on the lifting platform 410 along the radial direction of the rotating disk 210. The welding feed member 530 has a welding feed driving end that is transmission-connected to the laser welding head 510 and enables the laser welding head 510 to approach or move away from the welding station.

[0057] The grinding mechanism 600 of this embodiment includes: a grinding mounting seat 620, a grinding power source 611 and a grinding head 612. The grinding mounting seat 620 is mounted on the lifting platform 410 along the radial sliding of the rotating disk 210. The grinding power source 611 is mounted on the grinding mounting seat 620. The grinding power source 611 is drivingly connected to the grinding head 612 to rotate the grinding head 612. The grinding power source 611 is a servo drive motor, and its output shaft is coaxially fixedly connected to the grinding head 612. The grinding feed component 630 has a grinding feed drive end that is drivingly connected to the grinding mounting seat 620 and enables the grinding mounting seat 620 to approach or move away from the grinding station.

[0058] In actual use, the welding feed component 530 can drive the laser welding head 510 close to the welding station to perform welding processing on the charging pile on the welding station. When the rotating drive component 300 drives the positioning fixture 230 of the welding station to rotate, the laser welding head 510 can perform a circular path welding process on the circumference of the charging pile along the welding position. After the welding is completed, it can move away from the positioning fixture 230 to avoid the space for the rotating disk 210 to rotate. Similarly, the grinding power source 611 can drive the grinding head 612 to rotate at high speed. When the grinding feed component 630 drives the grinding mount 620 close to the grinding station, the grinding head 612 can grind the weld of the charging pile shell.

[0059] For a cylindrical charging pile, its welding path and grinding path are both extended in a circular arc, and when the positioning fixture 230 rotates, the distance between the laser welding head 510 and the grinding head 612 and the positioning fixture 230 remains unchanged. In other embodiments, for charging piles of other shapes, the welding and grinding processing paths are not extended in a circular arc route, and the welding feed component 530 and the grinding feed component 630 need to synchronously change the distance between the laser welding head 510 and the grinding head 612 and the positioning fixture 230 according to the rotation angle of the positioning fixture 230.

[0060] In this embodiment, the adjustment seat 520 and the grinding mounting seat 620 are respectively connected to the lifting platform 410 by linear slide rails. In order to ensure the accuracy of welding and grinding, in this embodiment, the welding feed component 530 and the grinding feed component 630 both adopt a linear drive module, that is, the lead screw nut assembly is driven by a servo motor to realize the feed drive of welding and grinding. In other embodiments, the adjustment seat 520 and the grinding mounting seat 620 can be connected to the lifting platform 410 by a sliding groove structure, and the welding feed component 530 and the grinding feed component 630 can adopt a linear drive component such as a cylinder, an electric push rod or a hydraulic push rod.

[0061] Refer to the attached Figures 1 to 3 In this embodiment, the welding station and the grinding station are arranged on the left and right sides of the front part of the turntable device 10, and the processing device 20 is arranged on the front side of the turntable device 10. The laser welding head 510 is slidably connected with the adjustment seat 520 along the front-to-back direction. The grinding mounting seat 620 is slidably connected with the lifting platform 410 along the front-to-back direction. The welding feed member 530 and the grinding feed member 630 are both arranged along the front-to-back direction.

[0062] In this embodiment, the rotation drive member 300 includes: a driving disk 310 and a rotation drive unit 330. The driving disk 310 is coaxially rotatably arranged in the middle of the rotating disk 210. Four positioning fixtures 230 are evenly distributed around the circumference of the driving disk 310. The rotation drive unit 330 is used to drive the driving disk 310 to rotate relative to the rotating disk 210.

[0063] A transmission roller 340 is disposed between the driving disc 310 and the positioning fixture 230. The outer periphery of the transmission roller 340 is in transmission contact with the driving disc 310 and the positioning fixture 230, so that the driving disc 310 and the positioning fixture 230 rotate synchronously.

[0064] When the rotation drive unit 330 drives the driving disk 310 to rotate, the transmission roller 340 can realize synchronous rotation with the driving disk 310 through the friction between its outer periphery and the driving disk 310. At the same time, the friction between it and the positioning fixture 230 can make the positioning fixture 230 rotate synchronously, thereby realizing the rotational drive of the driving disk 310 on the positioning fixture 230.

[0065] In this embodiment, the transmission roller 340 is elastically disposed on the rotating disk 210. A disc-shaped rotating driving ring 231 is coaxially disposed at the bottom of the positioning fixture 230. The rotating driving ring 231 is flush with the driving disk 310, and the outer edge of the transmission roller 340 elastically abuts against the outer periphery of the driving disk 310 and the rotating driving ring 231.

[0066] To facilitate loading and unloading, it is preferred that the positioning fixture 230 at the loading station and the unloading station remain stationary. In a further embodiment, the turntable device 10 is provided with a push-up component 700. The push-up component 700 includes: a push-up slider 710 and a push-up drive unit 720. The push-up slider 710 is in transmission connection with the drive roller 340. The push-up drive unit 720 is used to drive the push-up slider 710 to move so that the drive roller 340 is separated from the drive disk 310. The push-up drive unit 720 drives the push-up slider 710 to push the drive roller 340 open, so that the drive roller 340 can be disconnected from the drive disk 310.

[0067] In order to realize the rotation control of the positioning fixture 230 at different positions, the present invention provides multiple implementations.

[0068] The first implementation method: Figure 7 As shown, the push-opening member 700 is arranged on the rotating disk. The number of the push-opening members 700 is four. The four push-opening members 700 are arranged in a one-to-one correspondence with the four positioning fixtures 230.

[0069] In this embodiment, the push-opening member 700 that is rotated to the loading station and the unloading station is controlled to move, while the push-opening member 700 on the welding station and the grinding station does not move, thereby achieving the effect that the positioning fixture 230 at the loading station and the unloading station remains stationary, while the positioning fixture 230 at the welding station and the grinding station rotates driven by the driving disk 310.

[0070] In the first embodiment, the rotating disk 210 is slidably provided with a bearing slide 214. It is preferred that the sliding direction of the bearing slide 214 is perpendicular to the line connecting the positioning fixture 230 and the driving disk 310. A spring is provided between the bearing slide 214 and the rotating disk 210 so that the bearing slide 214 has a tendency to approach the driving disk 310 and the positioning fixture 230 under the action of elastic force. The transmission roller 340 is rotatably mounted on the bearing slide 214. The two ends of the spring are elastically abutted against the bearing slide 214 and the rotating disk 210, respectively, so that the transmission roller 340 is elastically pressed against the outer edge of the driving disk 310 and the rotating drive ring 231 of the positioning fixture 230.

[0071] The push-up slider 710 has a push-up end surface 712, and the push-up end surface 712 is inclined with respect to the moving direction of the push-up slider 710 and the sliding direction of the bearing slide 214. The bearing slide 214 is rotatably mounted on one end of the bearing slide 214, and the other end of the bearing slide 214 abuts against the push-up end surface 712. When the push-up drive unit 720 drives the push-up slider 710 to extend, the push-up end surface 712 can push the bearing slide 214 open, so that the bearing slider and the transmission roller 340 slide in a direction away from the drive disk 310 and the positioning fixture 230, thereby releasing the transmission connection between the drive disk 310 and the positioning fixture 230.

[0072] Furthermore, the sliding direction of the push-open slider 710 is arranged along the radial direction of the positioning fixture 230, and the push-open slider 710 has a positioning portion 711 at one end facing the positioning fixture 230. When the push-open slider 710 extends to push the transmission roller 340 away, the rotation drive ring 231 of the positioning fixture 230 can be pressed tightly by the positioning portion 711, so as to prevent the positioning fixture 230 from being deflected by external force during the loading and unloading process, thereby affecting the loading and unloading operation.

[0073] In this embodiment, the positioning portion 711 has an end surface extending in a circular arc and having the same shape as the outer edge of the rotation drive ring 231. Further, in order to increase the friction between the positioning portion 711 and the rotation drive ring 231, the positioning portion 711 may be provided with a rubber layer or anti-slip knurling.

[0074] The push-opening member 700 in the first embodiment is arranged on the rotating disk. To facilitate wiring, the rotating disk device 10 has a wiring channel that passes through from top to bottom. The pipeline of the push-opening drive unit 720 is arranged through the wiring channel to prevent the pipeline of the push-opening drive unit 720 from being torn off and damaged due to the continuous rotation of the rotating disk.

[0075] Specifically, a cylindrical drive shaft 320 is provided at the lower side of the drive disk 310. The drive shaft 320 is coaxially rotatably connected to the base 100, and the drive disk 310 is fixedly connected to the upper end of the drive shaft 320. A wiring hole is provided in the middle of the drive disk 310. The wiring hole is coaxially arranged with the inner cavity of the drive shaft 320 to form the wiring channel.

[0076] The rotation drive member 300 is fixedly mounted on the base 100. To ensure the rotation accuracy of the drive disk 310, the rotation drive member 300 can use a DD motor or a cam divider. In some other embodiments, the rotation drive member 300 can also use a rotation drive element such as a servo motor, a stepper motor or a pneumatic motor. The rotation drive member 300 and the drive shaft 320 can be connected to each other through a variety of transmission methods such as belt transmission, chain transmission, gear transmission or worm gear transmission.

[0077] Furthermore, in order to avoid obstruction to the wiring channel and the driving disk 310, the rotating disk 210 of this embodiment is in the shape of a circular disk.

[0078] A slot 212 is provided in the middle of the outer edge of the rotating disk 210. The slot 212 extends along the edge of the rotating disk 210. A positioning ring 211 and a driving gear ring 213 are provided on the upper and lower sides of the slot 212, respectively. The positioning ring 211 and the driving gear ring 213 both extend in a circular ring shape. The positioning ring 211, the driving gear ring 213 and the slot 212 are all coaxially arranged with the rotating disk 210.

[0079] The base 100 is provided with at least three positioning rollers 110. The positioning rollers 110 are in rolling contact with the positioning ring 211. The base 100 is provided with a plurality of wear-resistant pressure blocks 120. The wear-resistant pressure blocks 120 are fixedly mounted on the base 100 and have a clamping portion movably embedded in the slot 212. The lower end of the clamping portion is provided with a wear-resistant gasket that is in contact with the groove surface at the lower end of the slot 212.

[0080] Reference Figure 2 In this embodiment, the turntable driving member 220 includes a driving gear 221 and a turntable driving motor 222. The driving gear 221 is rotatably disposed on the base 100 and is in driving engagement with the driving gear ring 213. The output shaft of the turntable driving motor 222 is fixedly connected to the driving gear 221.

[0081] In other embodiments, the turntable driving component 220 may be a DD motor. In other embodiments, the turntable driving component 220 may be a rotation driving element such as a cam divider, a servo motor or a pneumatic motor.

[0082] Refer to the attached Figures 1 to 3 In this embodiment, the number of the positioning rollers 110 is four. The four positioning rollers 110 are arranged and distributed on the outer periphery of the rotating disk 210, and the outer edge of the positioning roller 110 rolls and abuts against the positioning ring 211. The positioning ring 211 is limited by the positioning roller 110, so that the rotating disk 210 can rotate around its own rotation axis. The wear-resistant pressure block 120 radially limits the rotating disk 210 through the abutment of the wear-resistant gasket with the card slot 212. When the turntable drive motor 222 drives the driving gear 221 to rotate, the rotating disk 210 rotates under the transmission action of the driving gear 221 and the driving gear ring 213, so that the positioning fixture 230 thereon is transferred to each workstation in turn.

[0083] The second implementation method: Figure 8As shown, the push-up member 700 is arranged on the base 100. The number of the push-up members 700 is two. The two push-up members 700 correspond to the loading station and the unloading station respectively. When the four positioning jigs 230 are respectively at the loading station, the welding station, the grinding station and the unloading station, the two push-up members 700 are actuated to push open the transmission rollers 340 on the loading station and the unloading station. When the driving disk 310 rotates, the positioning jigs 230 on the welding station and the grinding station rotate synchronously to realize welding and grinding processing, while the positioning jigs 230 on the loading station and the unloading station remain stationary, which is convenient for loading and unloading operations.

[0084] In the second embodiment, the push-up member 700 is arranged on the base 100, and does not rotate with the rotating disk, thereby avoiding the problem of wire tube entanglement of the push-up member 700. At the same time, the two push-up members 700 correspond to the loading station and the unloading station respectively, which reduces the number of push-up members 700, improves their utilization rate, and reduces equipment costs.

[0085] In the second embodiment, the transmission roller 340 can be elastically arranged by an elastic swing structure. The rotating disk 210 is provided with a rotating swing arm 215. The rotating swing arm 215 is rotatably connected to the rotating disk 210, and the transmission roller 340 is rotatably mounted on the rotating swing arm 215. The rotating swing arm 215 and the rotating disk 210 are elastically oscillatingly connected by a torsion spring, so that the transmission roller 340 is elastically pressed between the driving disk 310 and the positioning fixture 230.

[0086] Specifically, since the transmission roller 340 acts between the drive disk 310 and the positioning fixture 230, the push-up member 700 arranged on the outer periphery of the rotating disk is far away. The rotating swing arm 215 has a hinged portion, a driving portion and a swinging portion. The hinged portion is rotationally hinged with the rotating disk 210. The driving portion and the swinging portion are respectively arranged at two ends of the opposite sides of the hinged portion. The transmission roller 340 is rotatably mounted on the swinging portion, and the driving portion extends to the outer edge of the rotating disk 210. When the push-up slider 710 is extended and the positioning fixture 230 is pressed against by the positioning portion 711, the driving portion of the rotating swing arm 215 can be pushed open, so that the swinging portion rotates around the hinged portion, thereby causing the transmission roller 340 to be separated from the drive disk 310 and the positioning fixture 230.

[0087] In order to prevent the rotation of the rotating disk 210 from affecting the driving disk 310, in the turntable device 10 of this embodiment, the driving disk 310 and the rotating disk 210 rotate in the same direction, and the transmission roller 340 is a one-way bearing. The transmission roller 340 is arranged on the side of the line between the driving disk 310 and the positioning fixture 230 that faces away from the rotation direction.

[0088] One-way bearings are free to rotate in one direction but locked in the other direction. The metal shell of this bearing contains multiple rollers, needles or balls, and the shape of its rolling seat is designed so that it can only roll in one direction, and there will be great resistance in the other direction.

[0089] Specifically, refer to the attached Figure 3 Taking the example that the rotation directions of the driving disk 310 and the rotating disk 210 are both counterclockwise when viewed from above, the transmission roller 340 is arranged on the clockwise side of the line between the driving disk 310 and the positioning fixture 230.

[0090] The transmission roller 340 is pressed against between the driving disk 310 and the positioning fixture 230 under the action of elastic force, and the driving disk 310 and the positioning fixture 230 rotate synchronously with the transmission roller 340 under the action of friction force. When the rotating disk 210 remains stationary and the driving disk 310 rotates counterclockwise, the transmission roller 340 rotates clockwise, and the positioning fixture 230 rotates synchronously under the action of the transmission roller 340. When the driving disk 310 remains stationary and the rotating disk 210 rotates, the transmission roller 340 moves counterclockwise relative to the driving disk 310, and the transmission roller 340 has a tendency to rotate counterclockwise under the action of friction force. At this time, the reverse rotation resistance of the transmission roller 340 makes it resist the occurrence of counterclockwise rotation, and continuously resists the pressing elastic force, and generates sliding friction with the driving disk 310, without forcibly driving the driving disk 310 to reverse, causing damage to the rotating drive component 300.

[0091] Furthermore, in order to prevent the charging pile product from being loosened from the positioning fixture 230 due to the force exerted by the welding mechanism 500 and the grinding mechanism 600 on the charging pile product, the rotating disk 210 is provided with a plurality of abutting members. The abutting members are arranged one by one with the positioning fixture 230, and the abutting members are arranged on the radially inward side of the positioning fixture 230 along the rotating disk 210, and the abutting members have an abutting portion in the shape of an arc.

[0092] In actual use, the clamping member and the grinding member 610 are respectively arranged on opposite sides of the positioning fixture 230. The clamping member supports the charging pile product on the positioning fixture 230 through the arc-shaped clamping portion, offsets the radial force of the grinding mechanism 600 on the charging pile product, reduces the interaction force between the charging pile product and the positioning fixture 230, and avoids product deformation.

[0093] exist Fig. 9 and Fig.10 In the embodiment of the present invention, the number of the processing devices 20 is multiple.

[0094] In some embodiments, Fig. 9 As shown, the feeding directions of the welding mechanism 500 and the grinding mechanism 600 in the same processing device 20 are parallel to each other, and the processing feeding mechanism can synchronously drive the welding mechanism 500 and the grinding mechanism 600 to feed, and perform welding processing and grinding processing on the products on two adjacent positioning fixtures 230, thereby simplifying the structure of the processing feeding mechanism and reducing equipment costs.

[0095] However, for charging pile products with more complex processing paths, when the welding path changes in the height direction, in order to simplify the control program, the feeding direction of the welding mechanism 500 and the grinding mechanism 600 is set along the radius direction of the rotating disk 210. When the positioning fixture 230 reaches the welding station and the grinding station in turn, the laser welding head 510 and the grinding component 610 can align with the same point of the charging pile product. When the lifting drive mechanism 420 drives the lifting platform 410 to move up and down, the welding mechanism 500 and the grinding mechanism 600 in the same processing device 20 are synchronously lifted and lowered with the lifting platform 410, so as to realize the welding and grinding processing of the same processing position of the charging pile product.
