Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a clamp spot welding machine. Background Technology

[0002] Pipe clamps, also known as pipe clips or pipe clamps, are used to fasten pipe connections, ensuring a secure and airtight connection. Existing pipe clamps include... Figure 1 As shown, the clamp 100 includes an outer ring 110 and an inner ring 120. The outer ring 110 has a first notch 111, and the inner ring 120 has multiple second notches 121, one of which corresponds to the first notch 111. The inner ring 120 includes multiple inner layer plates 122, each of which is arc-shaped and is arranged sequentially and at intervals within the outer ring 110 to form the inner ring 120. The spacing between adjacent inner layer plates 122 forms the second notch 121. Each inner layer plate 122 is fixedly connected to the outer ring 110. When producing the clamp with the above structure, it is necessary to weld and fix each inner layer plate to the outer ring. The welding method is to first perform spot welding for initial fixation, and then perform full welding for reinforcement. The spot welding of the inner and outer rings of the clamp is completed using a clamp spot welding machine. Existing spot welding machines (such as the one disclosed in application number 201711489887.5) can only spot weld one inner plate and one outer ring at a time when spot welding the clamps of the above structure, and cannot spot weld multiple inner plates and one outer ring at the same time, resulting in low spot welding efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a clamp spot welding machine to solve the technical problem that the existing spot welding machine cannot simultaneously spot weld multiple inner plates and outer rings, resulting in low spot welding efficiency.

[0004] To achieve the above technical objectives, the present invention provides a clamp spot welding machine, comprising:

[0005] A rack, comprising a platform having a first ring and a second ring arranged concentrically from the inside out;

[0006] The spot welding mechanism includes multiple first electrodes and multiple second electrodes. Each first electrode is spaced apart along a first ring line, and each second electrode is spaced apart along a second ring line and is electrically connected to each first electrode in a one-to-one correspondence. Each first electrode can move synchronously back and forth along the radial direction of the first ring line to abut or separate from each inner layer plate of the clamp in a one-to-one correspondence. Each second electrode can move synchronously back and forth along the radial direction of the second ring line to abut or separate from the outer ring of the clamp.

[0007] Furthermore, a circular working opening is provided on the platform, the first ring line is concentrically arranged with the working opening, and the diameter of the first ring line is smaller than the diameter of the working opening, while the diameter of the second ring line is larger than the diameter of the working opening. The area on the side of the working opening is used to place clamps.

[0008] Furthermore, the spot welding mechanism also includes a first moving drive assembly, which is connected to each of the first electrodes and is used to drive each of the first electrodes to move synchronously back and forth along the radial direction of the first ring line, so that each of the first electrodes is in one-to-one correspondence with each of the inner layer plates and either abuts or separates.

[0009] Furthermore, the spot welding mechanism also includes a second moving drive assembly, which is connected to each of the second electrodes and is used to drive each of the second electrodes to move synchronously and reciprocally along the radial direction of the second ring line so as to abut or separate from the outer ring.

[0010] Furthermore, the second moving drive assembly includes multiple fixed seats and multiple first telescopic drive members. Each fixed seat is circumferentially disposed on the outer side of the second ring line. The fixed end of each first telescopic drive member is fixedly connected to each fixed seat in a one-to-one correspondence. The telescopic end of each first telescopic drive member is fixedly connected to each second electrode in a one-to-one correspondence, for driving the second electrode to reciprocate radially along the second ring line.

[0011] Furthermore, the clamp spot welding machine also includes a clamping mechanism, which includes multiple clamping members and a clamping drive assembly. Each of the clamping members is spaced apart along the first ring line. The clamping drive assembly is connected to each of the clamping members and is used to drive each of the clamping members to move synchronously back and forth radially along the first ring line, so that each of the clamping members is in one-to-one contact with each of the inner plates of the clamp and is either pressed together or separated, and each of the inner plates is pressed together with the outer ring.

[0012] Furthermore, the clamping member includes a main clamping plate and two auxiliary clamping plates. The main clamping plate is arc-shaped and is used to abut against the inner sidewall of the inner layer plate. The two auxiliary clamping plates are respectively fixedly connected to both ends of the main clamping plate and are respectively used to abut against both ends of the inner layer plate. The clamping drive assembly is connected to the middle of the main clamping plate.

[0013] Furthermore, the clamp spot welding machine also includes a lifting mechanism, which is connected to the clamping drive assembly and is used to drive the clamping drive assembly to move up and down so that each clamping member moves into or out of the inner ring of the clamp.

[0014] Furthermore, the lifting mechanism includes a support frame and a second telescopic drive component. The support frame is fixedly connected to the clamping drive assembly, and the output end of the second telescopic drive component is fixedly connected to the support frame for driving the support frame to move up and down.

[0015] Furthermore, the clamp spot welding machine also includes a rotating mechanism, and the clamping mechanism includes at least two clamping mechanisms, each of which is circumferentially distributed. The lifting mechanism is connected to each of the clamping drive components, and the rotating mechanism is connected to the lifting mechanism to drive the lifting mechanism to rotate in the horizontal plane so that each of the clamping mechanisms sequentially reaches directly above the spot welding mechanism.

[0016] Compared with the prior art, the beneficial effects of this utility model include: During use, the clamp to be spot-welded is placed on a platform, positioned within the area between the first and second ring lines, and kept concentric with both the first and second ring lines. Then, each first electrode is moved synchronously back and forth radially along the first ring line until each first electrode is pressed against the corresponding inner layer plate of the clamp. Simultaneously, each second electrode is moved synchronously back and forth radially along the second ring line until it is pressed against the outer ring of the clamp. At this point, each second electrode corresponds one-to-one with each first electrode. When the electrically connected circuit is turned on, the current passes through the contact points of the clamp, generating resistance heat that melts it locally. Then, each first electrode quickly separates from each inner layer plate of the clamp, and each second electrode quickly separates from the outer ring of the clamp. At this time, the electrical connection between each second electrode and each first electrode is cut off, and the current is disconnected. As the current is disconnected, the molten metal quickly solidifies to form a weld point, thereby achieving spot welding of the clamp. When spot welding the clamp of this structure, this clamp spot welding machine can simultaneously spot weld multiple inner layer plates and outer rings, resulting in high spot welding efficiency.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] This utility model provides a clamp spot welding machine, the structure of which is as follows: Figure 2 - Figure 4 As shown, the device includes a frame 200 and a spot welding mechanism 300. The frame 200 includes a platform 210, on which a first ring and a second ring are concentrically arranged from the inside out. The spot welding mechanism 300 includes a plurality of first electrodes 310 and a plurality of second electrodes 320. Each first electrode 310 is spaced apart along the first ring, and each second electrode 320 is spaced apart along the second ring and is electrically connected to each first electrode 310 in a one-to-one correspondence. Each first electrode 310 can move synchronously back and forth along the radial direction of the first ring to abut or separate from each inner layer plate 122 of the clamp 100 in a one-to-one correspondence. Each second electrode 320 can move synchronously back and forth along the radial direction of the second ring to abut or separate from the outer ring 110 of the clamp 100.

[0026] In use, the clamp 100 to be spot welded is placed on the platform 210, and the clamp 100 is positioned within the area between the first ring line and the second ring line, maintaining concentricity between the clamp 100 and the first and second ring lines. Then, each of the first electrodes 310 is moved synchronously back and forth radially along the first ring line until each of the first electrodes 310 is in contact with each of the inner plates 122 of the clamp 100. Simultaneously, each of the second electrodes 320 is moved synchronously back and forth radially along the second ring line until each of the second electrodes 320 is in contact with the outer ring 110 of the clamp 100. At this point, each of the second electrodes 320 corresponds one-to-one with each of the first electrodes 310. When the electrically connected circuit is turned on, the current passes through the contact points of the clamp 100, generating resistance heat that melts it locally. Then, each of the first electrodes 310 quickly separates from each of the inner layer plates 122 of the clamp 100, and each of the second electrodes 320 quickly separates from the outer ring 110 of the clamp 100. At this time, the electrical connection between each of the second electrodes 320 and each of the first electrodes 310 is cut off, and the current is disconnected. As the current is disconnected, the molten metal quickly solidifies to form a weld point, thereby achieving spot welding of the clamp 100. When spot welding the clamp 100 of this structure, this clamp spot welding machine can simultaneously spot weld multiple inner layer plates 122 and outer ring 110, resulting in high spot welding efficiency.

[0027] In a preferred embodiment, the spot welding mechanism 300 further includes a power supply component, which supplies power to the first electrode 310 and the corresponding second electrode 320. The power supply component includes a power source and multiple circuit breakers. The positive terminal of the power source is electrically connected to one contact of each of the multiple circuit breakers via multiple wires. The other contact of each circuit breaker is electrically connected to each of the first electrodes 310 via wires. Each circuit breaker is used to control the conduction and disconnection of each circuit. The negative terminal of the power source is electrically connected to each of the second electrodes 320 via multiple wires.

[0028] As a preferred embodiment, please refer to Figure 1 and Figure 3 The clamp 100 has three inner layer plates 122, and the first electrode 310 includes three, the number of the first electrode 310 is equal to the number of the inner layer plates 122 of the clamp 100. The second electrode 320 includes six, wherein every two second electrodes 320 correspond to one first electrode 310.

[0029] As a preferred embodiment, please refer to Figure 3The platform 210 has a circular working opening 211. The first ring line is concentrically arranged with the working opening 211, and the diameter of the first ring line is smaller than the diameter of the working opening 211. The diameter of the second ring line is larger than the diameter of the working opening 211. The area on the side of the working opening 211 is used to place the clamp 100, so that each of the first electrodes 310 can be located within the inner ring 120 of the clamp 100.

[0030] As a preferred embodiment, please refer to Figure 3 and Figure 5 The spot welding mechanism 300 further includes a first moving drive component 330, which is connected to each of the first electrodes 310 and is used to drive each of the first electrodes 310 to move synchronously back and forth along the radial direction of the first ring line, so that each of the first electrodes 310 is in one-to-one correspondence with each of the inner layer plates 122 and is either pressed together or separated. By operating the first moving drive component 330, the first moving drive component 330 can drive each of the first electrodes 310 to move synchronously back and forth along the radial direction of the first ring line, so that each of the first electrodes 310 is in one-to-one correspondence with each of the inner layer plates 122 and is either pressed together or separated.

[0031] As a preferred embodiment, please refer to Figure 5The first moving drive assembly 330 is disposed within the working port 211. The first moving drive assembly 330 includes a first mounting base, a plurality of first sliding blocks, a plurality of first connecting rods, a first rotating disk, a plurality of first connecting shafts, and a first rotating drive component. The first mounting base is a columnar structure and concentric with the first annular line. A plurality of first sliding grooves extending radially are circumferentially formed on the first mounting base. Each first sliding block is slidably connected to each of the first sliding grooves. The lower end of each first connecting rod is fixedly connected to the outer end of each first sliding block. The upper end of each first connecting rod is fixedly connected to each of the first electrodes 310. The first rotating disk is concentrically arranged with the first mounting base. A plurality of radially distributed first arc-shaped grooves are circumferentially formed on the first rotating disk. The lower end of each first connecting shaft corresponds to each of the first arc-shaped grooves. The sliding connection is used, with the upper end of each of the first connecting shafts fixedly connected to the inner end of each of the first sliding blocks. The first rotation drive is fixedly connected to the first mounting base, and the output end of the first rotation drive is concentrically fixedly connected to the first rotating disk. It is used to drive the first rotating disk to rotate in the forward or reverse direction. By operating the first rotation drive, the output end of the first rotation drive rotates in the forward direction, which in turn drives the first rotating disk to rotate in the forward direction. Since each of the first sliding blocks is restricted by the corresponding first groove and the first connecting shaft, when the first rotating disk rotates in the forward direction, each of the first sliding blocks can move outward along the corresponding first groove, thereby driving each of the first electrodes 310 to move outward synchronously along the radial direction of the first ring line via each of the first connecting rods. This allows each of the first electrodes 310 to be pressed against each of the inner layer plates 122 in a corresponding manner.

[0032] As a preferred embodiment, please refer to Figure 5 The first moving drive component 330 may adopt a first three-jaw chuck, and the selected first three-jaw chuck is of the brand Zero Point Prince and model SC.

[0033] As a preferred embodiment, please refer to Figure 3 The spot welding mechanism 300 further includes a second moving drive component 340, which is connected to each of the second electrodes 320 and is used to drive each of the second electrodes 320 to move synchronously back and forth along the radial direction of the second ring line so as to abut or separate from the outer ring 110. By operating the second moving drive component 340, the second moving drive component 340 can drive each of the second electrodes 320 to move synchronously back and forth along the radial direction of the second ring line, so that each of the second electrodes 320 can abut or separate from the outer ring 110.

[0034] As a preferred embodiment, please refer to Figure 3 The second moving drive assembly 340 includes a plurality of fixed seats 341 and a plurality of first telescopic drive members 342. Each of the fixed seats 341 is circumferentially disposed on the outer side of the second ring line. The fixed ends of each of the first telescopic drive members 342 are fixedly connected to each of the fixed seats 341 in a one-to-one correspondence. The telescopic ends of each of the first telescopic drive members 342 are fixedly connected to each of the second electrodes 320 in a one-to-one correspondence. The first telescopic drive members 342 can be manipulated to extend their telescopic ends synchronously, thereby driving each of the second electrodes 320 to move radially along the second ring line until each of the second electrodes 320 is pressed against the outer ring 110.

[0035] As a preferred embodiment, please refer to Figure 3 Each of the fixed seats 341 is fixedly connected to the platform 210, and the platform 210 can support each of the fixed seats 341.

[0036] As a preferred embodiment, please refer to Figure 3 and Figure 4 The clamp spot welding machine further includes a clamping mechanism 400, which includes multiple clamping members 410 and a clamping drive assembly 420. Each clamping member 410 is spaced apart along the first ring line. The clamping drive assembly 420 is connected to each clamping member 410 and drives each clamping member 410 to reciprocate radially along the first ring line synchronously, so that each clamping member 410 is in one-to-one contact with or separates from each inner layer plate 122 of the clamp 100, and each inner layer plate 122 is in contact with the outer ring 110, placing the clamp 100 to be spot welded on the platform 210. Positioning the clamp 100 within the area between the first and second ring lines, the clamping drive assembly 420 is manipulated to drive each clamping member 410 to reciprocate synchronously along the radial direction of the first ring line. This causes each clamping member 410 to abut against each inner layer plate 122 of the clamp 100, and also abuts against the outer ring 110. This ensures that the inner layer plates 122 and the outer ring 110 are in close contact, facilitating circuit conduction and avoiding the need for manual contact between the inner layer plates 122 and the outer ring 110.

[0037] As a preferred embodiment, please refer to Figure 4The clamping member 410 includes a main clamping plate 411 and two auxiliary clamping plates 412. The main clamping plate 411 is arc-shaped and is used to abut against the inner sidewall of the inner layer plate 122. The two auxiliary clamping plates 412 are fixedly connected to both ends of the main clamping plate 411 and are respectively used to abut against both ends of the inner layer plate 122. The clamping drive assembly 420 is connected to the middle of the main clamping plate 411. Because existing spot welding machines cannot spot weld the inner and outer rings 110 of the clamp 100 onto the individual inner layer plates 12 of the inner ring 120. 2. Precise positioning is crucial. Inconsistent spacing between adjacent inner plates 122 of the clamp 100 can prevent the clamp 100 from meeting production requirements, resulting in a low yield. This clamp spot welding machine, through its clamping components 410, can precisely position each inner plate 122, ensuring equal spacing between adjacent inner plates 122. This prevents inconsistent spacing between adjacent inner plates 122 of the clamp 100, guarantees that the clamp 100 meets production requirements, and improves the yield of the clamp 100.

[0038] As a preferred embodiment, please refer to Figure 4 The main clamping plate 411 has an insertion hole 4111. The first electrode 310 slides through the insertion hole 4111 to abut against the inner layer plate 122, thereby allowing the first electrode 310 to contact the inner layer plate 122.

[0039] As a preferred embodiment, please refer to Figure 4 and Figure 6The clamping drive assembly 420 includes a second mounting base, a plurality of second sliding blocks, a plurality of second connecting rods, a second rotating disk, a plurality of second connecting shafts, and a second rotating drive component. The second mounting base is a columnar structure and concentric with the first ring line. A plurality of second sliding grooves extending radially are circumferentially formed on the second mounting base. Each second sliding block is slidably connected to each of the second sliding grooves. The upper end of each second connecting rod is fixedly connected to the outer end of each of the first sliding blocks, and the lower end of each second connecting rod is fixedly connected to each of the clamping components 410. The second rotating disk is concentrically arranged with the second mounting base. A plurality of radially distributed second arc-shaped grooves are circumferentially formed on the second rotating disk. The upper end of each second connecting shaft is slidably connected to each of the second arc-shaped grooves, and the lower end of each second connecting shaft is fixedly connected to the inner end of each of the second sliding blocks. The second rotating drive component is connected to the second mounting base. The second mounting base is fixedly connected, and the output end of the second rotation drive is concentrically fixedly connected to the second rotating disk, which is used to drive the second rotating disk to rotate in the forward or reverse direction. By operating the second rotation drive, the output end of the second rotation drive rotates in the forward direction, and drives the second rotating disk to rotate in the forward direction. Since each of the second sliding blocks is restricted by the corresponding second slide groove and the second connecting shaft, when the second rotating disk rotates in the forward direction, each of the second sliding blocks can move outward along the corresponding second slide groove, thereby driving each of the clamping members 410 to move outward synchronously along the radial direction of the first ring line via each of the second connecting rods. This allows the main clamping plate 411 of each of the clamping members 410 to abut against the inner sidewall of each of the inner layer plates 122, and the two auxiliary clamping plates 412 of each of the clamping members 410 to abut against the two ends of each of the inner layer plates 122 respectively. Each of the inner layer plates 122 and the outer ring 110 can be kept in abutting state.

[0040] As a preferred embodiment, please refer to Figure 6 The clamping drive assembly 420 may be a second three-jaw chuck, and the selected second three-jaw chuck is of the brand Zero Point Prince and model SC.

[0041] As a preferred embodiment, please refer to Figure 2The clamp spot welding machine further includes a lifting mechanism 500, which is connected to the clamping drive assembly 420 and is used to drive the clamping drive assembly 420 to move up and down so that each clamping member 410 moves into or out of the inner ring 120 of the clamp 100. After the clamp 100 is spot welded, by operating the lifting mechanism 500, the lifting mechanism 500 can drive the clamping drive assembly 420 to move upward so that each clamping member 410 moves out of the inner ring 120 of the clamp 100, making it easy to remove the spot-welded clamp 100.

[0042] As a preferred embodiment, please refer to Figure 2 The lifting mechanism 500 includes a support frame 510 and a second telescopic drive member 520. The support frame 510 is fixedly connected to the clamping drive assembly 420. The output end of the second telescopic drive member 520 is fixedly connected to the support frame 510 and is used to drive the support frame 510 to move up and down. By operating the second telescopic drive member 520, the telescopic end of the second telescopic drive member 520 can be extended or shortened, thereby driving the support frame 510 to move up or down, and driving the clamping drive assembly 420 to move up or down, so that each clamping member 410 moves into or out of the inner ring 120 of the clamp 100.

[0043] In a preferred embodiment, the support frame 510 is fixedly connected to the second mounting base, thereby enabling connection with the clamping drive assembly 420.

[0044] As a preferred embodiment, please refer to Figure 2The clamp spot welding machine further includes a rotating mechanism 600. The clamping mechanisms 400 include at least two units, each arranged circumferentially. The lifting mechanism 500 is connected to each of the clamping drive assemblies 420. The rotating mechanism 600 is connected to the lifting mechanism 500 and drives the lifting mechanism 500 to rotate in a horizontal plane, so that each clamping mechanism 400 sequentially reaches directly above the spot welding mechanism 300. By manipulating the rotating mechanism 600, the lifting mechanism 500 can be driven to rotate in a horizontal plane, so that each clamping mechanism 400 sequentially reaches directly above the spot welding mechanism 300. When the clamping mechanism 400 reaches... When directly above the spot welding mechanism 300, by operating the lifting mechanism 500, the lifting mechanism 500 can drive each of the clamping mechanisms 400 to move downward, so that each of the clamping members 410 of the clamping mechanism 400 located directly above the spot welding mechanism 300 can move into the inner ring 120 of the clamp 100. Then, by operating the clamping drive assembly 420, the clamping drive assembly 420 can drive each of the clamping members 410 to move synchronously and radially along the first ring line, so that each of the clamping members 410 is pressed against each of the inner layer plates 122 of the clamp 100, and each of the inner layer plates 122 is pressed against the outer ring 110, and each of the inner layer plates 122 and the outer ring 110 can be kept in a pressed state.

[0045] In a preferred embodiment, the support frame 510 is fixedly connected to each of the second mounting seats, thereby achieving connection with each of the clamping drive components 420.

[0046] As a preferred embodiment, please refer to Figure 2 The rotating mechanism 600 includes a support base 610 and a third rotating drive member 620. The support base 610 is fixedly connected to the fixed end of the second telescopic drive member 520. The output end of the third rotating drive member 620 is fixedly connected to the support base 610 and is used to drive the fixed base 341 to rotate. By operating the third rotating drive member 620, the output end of the third rotating drive member 620 can rotate, thereby driving the second telescopic drive member 520 to rotate via the support base 610, and then driving each of the clamping mechanisms 400 to rotate via the support frame 510, so that each of the clamping mechanisms 400 sequentially reaches directly above the spot welding mechanism 300, thereby improving the welding efficiency of the clamp 100.

[0047] As a preferred embodiment, please refer to Figure 2The frame 200 also includes a chassis 220. The bottom of the platform 210 is fixedly connected to the top of the chassis 220 via a column. The bottom of the first mounting base is fixedly connected to the top of the chassis 220. The fixed end of the third rotation drive 620 is fixedly connected to the chassis 220.

[0048] As a preferred embodiment, please refer to Figure 2 The frame 200 also includes a receiving trough 230, which is located on the side of the platform 210 and fixedly connected to the housing 220. During the rotation of the lifting mechanism 500 in the horizontal plane, each of the clamping mechanisms 400 sequentially reaches directly above the spot welding mechanism 300 and the receiving trough 230. When the spot welding mechanism 300 performs spot welding on the clamp 100, the receiving trough 230 receives the welded clamp 100, realizing that spot welding and material collection are carried out simultaneously, thereby improving the production efficiency of the clamp 100.

[0049] In a preferred embodiment, the clamp spot welding machine further includes a control system. The control system is electrically connected to the first rotary drive, the second rotary drive, the third rotary drive 620, the first telescopic drive 342, and the second telescopic drive 520. The control system is used to control the start and stop of the first rotary drive, the second rotary drive, the third rotary drive 620, the first telescopic drive 342, and the second telescopic drive 520, and to monitor the position of each clamping mechanism 400.

[0050] To better understand this utility model, the following is combined with... Figure 1 - Figure 6 The working principle of the technical solution of this utility model will be described in detail below:

[0051] In use, the clamp 100 to be spot welded is placed on the platform 210, and the clamp 100 is positioned in the area between the first ring and the second ring. By manipulating the second telescopic drive member 520, the telescopic end of the second telescopic drive member 520 is shortened, thereby driving the support frame 510 to move downward and driving the clamping mechanism 400 to move downward, so that each clamping member 410 moves into the inner ring 120 of the clamp 100. Then, the clamping drive assembly 420 is manipulated so that the clamping drive assembly 420 can drive each clamping member 410 to move synchronously back and forth radially along the first ring, so that the main clamping plate 411 of each clamping member 410 abuts against the inner sidewall of each inner layer plate 122. The two auxiliary clamping plates 412 of each clamping member 410 abut against the two ends of each inner layer plate 122, and each inner layer plate 122 and the outer ring 110 can be kept in a tight abutment state. By operating the first moving drive assembly 330, the first moving drive assembly 330 can drive each first electrode 310 to move synchronously along the radial direction of the first ring line until each first electrode 310 abuts against each inner layer plate 122 of the clamp 100. At the same time, by operating the second moving drive assembly 340, the second moving drive assembly 340 can drive each second electrode 320 to move synchronously along the radial direction of the second ring line until each second electrode 320 abuts against the outer ring 110 of the clamp 100. At this time, the circuit connecting each of the second electrodes 320 and each of the first electrodes 310 is turned on, and the current generates resistance heat through the contact points of the clamp 100, causing it to melt locally. Then, each of the first electrodes 310 quickly separates from each of the inner plates 122 of the clamp 100, and each of the second electrodes 320 quickly separates from the outer ring 110 of the clamp 100. At this time, the circuit connecting each of the second electrodes 320 and each of the first electrodes 310 is cut off, and the current is disconnected. As the current is disconnected, the molten metal quickly solidifies to form a weld point, thereby achieving spot welding of the clamp 100. After the spot welding of the clamp 100 is completed, the second telescopic drive component 520 is operated to... The telescopic drive 520 extends its telescopic end, thereby driving the support frame 510 to move upward and causing the clamping mechanism 400 to move upward, so that the clamp 100 moves upward to a preset position. Then, the third rotation drive 620 is operated, and the output end of the third rotation drive 620 can rotate, thereby driving the second telescopic drive 520 to rotate via the support base 610, and then driving each of the clamping mechanisms 400 to rotate via the support frame 510. Each of the clamping mechanisms 400 sequentially reaches directly above the spot welding mechanism 300 and the receiving groove 230. The clamp 100, which has been spot welded, can reach directly above the receiving groove 230, and the clamping mechanism 400 releases its grip on the clamp 100.The clamp 100 falls into the receiving groove 230. When spot welding the clamp 100 of this structure, the clamp spot welding machine can simultaneously spot weld multiple inner layer plates 122 to the outer ring 110, resulting in high spot welding efficiency.

[0052] The clamp spot welding machine provided by this utility model has the following beneficial effects:

[0053] (1) When the spot welding mechanism 300 performs spot welding on the clamp 100, the receiving groove 230 receives the welded clamp 100, realizing that spot welding and material collection are carried out simultaneously, which improves the production efficiency of the clamp 100.

[0054] (2) In this clamp spot welding machine, the main clamping plate 411 of each clamping member 410 abuts against the inner sidewall of each inner layer plate 122, and the two auxiliary clamping plates 412 of each clamping member 410 abut against the two ends of each inner layer plate 122 respectively. This allows for precise positioning of each inner layer plate 122, ensuring that the spacing between adjacent inner layer plates 122 is equal, avoiding uneven spacing between adjacent inner layer plates 122 of the clamp 100, ensuring that the clamp 100 meets production requirements, and improving the yield of the clamp 100.

[0055] (3) When the clamp spot welding machine performs spot welding on the clamp 100 of this structure, it can simultaneously spot weld multiple inner plates 122 and outer ring 110, and the spot welding efficiency is high.

[0056] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
