Description

Technical Field

[0001] The present application relates to the field of welding machines, and in particular to a car door latch welding machine. Background Art

[0002] An automotive door lock primarily consists of a lock body, a latch, and a drive mechanism. The latch (sometimes also called a lock ring or lock pin) is the mating component of the lock body and is typically mounted on the vehicle body in a position corresponding to the lock body. The latch is bolted to a latch mounting plate. The latch is welded from a high-strength alloy steel wire (the latch ring) to a high-strength automotive structural steel plate (the base plate).

[0003] In the prior art, a hot riveting spot welder is often used to weld the buckle to the base plate. A common hot riveting spot welder mainly includes a frame, on which a clamp, a welding mechanism, a drive mechanism, etc. are installed. The welding mechanism is fixedly mounted on the drive mechanism, which drives the welding mechanism up and down, and the welding head of the welding mechanism is mounted above the clamp. When welding the lock buckle, the operator fixes the buckle and the base plate on the clamp, and the drive mechanism drives the welding mechanism downward so that the welding head on the welding mechanism contacts the rivet point on the lock buckle. After the rivet point melts, the end of the buckle is welded to the base plate. The drive mechanism drives the welding mechanism to reset, and the melted rivet point between the buckle and the base plate cools and solidifies to complete the welding.

[0004] The fixture on a common buckle welding machine mainly consists of two clamping seats, one of which is fixed to the frame, and the other is slidably mounted on the frame. The slidable clamping seat is driven by a handwheel and screw mechanism. During the actual welding process, the operator needs to use the handwheel and screw mechanism to drive the sliding clamping seat to press against the fixed clamping seat to achieve the fixing of the buckle and the base plate. However, the method of fixing the buckle and the base plate through the handwheel and screw mechanism is relatively cumbersome and inefficient, and there is room for improvement. Utility Model Content

[0005] In order to improve the efficiency of operators in welding automobile door lock buckles using a welding machine, the present application provides an automobile door lock buckle welding machine.

[0006] The present application provides a car door lock welding machine that adopts the following technical solutions:

[0007] An automobile door lock buckle welding machine comprises a frame, a workbench fixedly mounted on the frame, a fixture fixedly mounted on the workbench, the fixture being located directly below a welding mechanism, a first clamping seat detachably mounted on the clamp, an automatic clamping drive member fixedly mounted on the clamp, a second clamping seat detachably mounted on a driving end of the automatic clamping drive member, a positioning groove adapted for a buckle formed between the first clamping seat and the second clamping seat;

[0008] Two support plates are fixedly mounted on the clamp, the two support plates are respectively mounted above the first clamp seat and the second clamp seat, and the two ends of the bottom plate are respectively placed on the two support plates;

[0009] A positioning mechanism for fixing the bottom plate of the lock is installed at the bottom of the welding mechanism, and the positioning mechanism is set above the two support plates.

[0010] By adopting the above technical solution, during the actual production and processing process, after the operator assembles the buckle on the base plate, the operator aligns the buckle with the positioning groove between the first clamping seat and the second clamping seat, and places the base plate on the two support plates; the operator controls the automatic clamping drive to drive the second clamping seat to slide in the direction close to the second clamping seat until the buckle is tightly pressed between the first clamping seat and the second clamping seat; then, the operator can control the driving mechanism of the welding machine to drive the welding mechanism down until the welding head contacts the two melting points on the lock, and perform hot melt spot welding on the buckle and the base plate. Through the setting of the automatic clamping drive, the operator does not need to clamp the buckle through the handwheel screw structure, which can effectively improve the convenience of using the welding machine and improve the efficiency of welding the lock. In addition, since a positioning mechanism is installed on the welding mechanism, the base plate can be fixed during the welding process, reducing the occurrence of shaking and offset of the base plate and buckle during welding, which affects the welding accuracy.

[0011] Preferably, a fixing block is detachably mounted on the clamp, and the fixing block is located below the first clamp seat. A limiting groove adapted to the lower half of the buckle is provided on the side wall of the fixing block close to the second clamp seat.

[0012] By adopting the above technical solution, the limiting groove can limit the lower half of the buckle, thereby reducing the deformation of the lower half of the buckle due to heat.

[0013] Preferably, the automatic clamping drive member includes a cylinder, the cylinder body of the cylinder is fixedly mounted on the clamp, the driving shaft of the cylinder is fixedly mounted with a connecting seat, and the second clamping seat is detachably fixedly mounted on the connecting seat.

[0014] By adopting the above technical solution, the cylinder can drive the second clamping seat to slide toward or away from the first clamping seat by extending or retracting the driving shaft, thereby achieving the technical effect of automatic clamping and releasing the lock.

[0015] Preferably, a guide rail is fixedly mounted on the clamp, a slider is fixedly mounted on the bottom of the connecting seat, and a sliding groove adapted to the guide rail is provided on the slider;

[0016] Limiting protrusions are integrally formed on both sides of the guide rail, and limiting grooves adapted to the limiting protrusions are respectively opened on the inner side walls opposite to each other of the slide grooves, and the two limiting protrusions are respectively embedded and installed in the two limiting grooves.

[0017] By adopting the above technical solution, the guide rail and the slider are used in conjunction with each other to limit the sliding trajectory of the connecting seat during sliding, effectively reducing the possibility of misalignment between the first clamping seat and the second clamping seat. The limiting groove and the limiting protrusion can also prevent the slider from falling off the guide rail, further ensuring the sliding stability of the connecting seat and the second clamping seat.

[0018] Preferably, the welding mechanism includes a welding seat, which is slidably connected to a plurality of positioning rods, and the two ends of the plurality of positioning rods are respectively fixedly connected to anti-slip blocks, and the positioning rods are coaxially sleeved with springs, and the springs are tightly pressed between the welding seat and the anti-slip blocks.

[0019] By adopting the above technical solution, when the lifting mechanism drives the welding mechanism to move downward, the end of the positioning rod contacts the top of the base plate, the spring is compressed, and the positioning rod slides upward. The spring can form a downward elastic force on the base plate, which can achieve a clamping and fixing effect on the base plate, reducing the occurrence of displacement and shaking of the base plate during welding.

[0020] Preferably, two vertical plates are fixedly installed on the clamp, and the two vertical plates are respectively located on both sides of the first clamp seat and the second clamp seat, and the two ends of the two support plates are respectively detachably connected to the top of the two vertical plates, and U-shaped grooves are respectively opened through the two vertical plates.

[0021] By adopting the above technical solution, the U-shaped groove can facilitate the operator to observe the position of the buckle when installing the buckle and the base plate, and facilitate the operator to fix the buckle on the first clamping seat and the fixing block.

[0022] Preferably, a discharging slide rail arranged to be inclined downward is fixedly mounted on the frame, and a discharging port for the discharging slide rail to extend out of the frame is opened on the frame, and the discharging slide rail passes through the port and extends outside the frame, and the inlet of the discharging slide rail is opposite to the U-shaped groove on the vertical plate.

[0023] By adopting the above technical solution, when the lock is welded, the operator can control the cylinder to drive the second clamp to slide away from the first clamp and release the lock. Then the user can use tools to transfer the welded lock through the U-shaped groove to the discharge slide rail and send it out, which can improve the efficiency of removing the lock and further improve the efficiency of welding the lock.

[0024] Preferably, a safety grating is fixedly mounted on the frame.

[0025] By adopting the above technical solution and setting a safety grating, an automatic alarm can be sounded when an operator performs a dangerous operation during the welding process of the welding mechanism, thereby improving the safety of the welding machine.

[0026] In summary, the automobile door lock welding machine of the present application has at least one of the following beneficial technical effects:

[0027] 1. During the actual production process, after the operator assembles the buckle on the base plate, the operator aligns the buckle with the positioning groove between the first clamping seat and the second clamping seat, and places the base plate on the two support plates; the operator controls the automatic clamping drive member to drive the second clamping seat to slide in the direction close to the second clamping seat until the buckle is tightly pressed between the first clamping seat and the second clamping seat; then, the operator can control the driving mechanism of the welding machine to drive the welding mechanism downward until the welding head contacts the two melting points on the lock buckle, and perform hot melt spot welding on the buckle and the base plate. Through the setting of the automatic clamping drive member, the operator does not need to clamp the buckle using the handwheel screw structure, which can effectively improve the convenience of using the welding machine and improve the efficiency of welding the lock buckle;

[0028] 2. Since the welding mechanism is equipped with a positioning mechanism, the base plate can be fixed during the welding process, reducing the shaking and offset of the base plate and retaining ring during the welding process, which may affect the welding accuracy;

[0029] 3. When the lock is welded, the operator can control the cylinder to drive the second clamp to slide away from the first clamp, releasing the lock. The user can then use tools to transfer the welded lock through the U-shaped groove to the discharge slide rail and send it out, which can improve the efficiency of lock removal and further improve the efficiency of lock welding.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] Example

[0036] The embodiment of the present application discloses a car door lock welding machine. Figure 1-Figure 3 It mainly includes a frame 1, a workbench 2 is fixedly installed on the frame 1, a clamp 3 is fixedly installed on the workbench 2, the clamp 3 is located directly below the welding mechanism 4, a first clamping seat 31 is detachably installed on the clamp 3, an automatic clamping driving member 32 is fixedly installed on the clamp 3, and a second clamping seat 33 is detachably installed on the driving end of the automatic clamping driving member 32, and a positioning groove 34 adapted to the buckle 52 is formed between the first clamping seat 31 and the second clamping seat 33; two support plates 35 are fixedly installed on the clamp 3, and the two support plates 35 are respectively mounted above the first clamping seat 31 and the second clamping seat 33, and the two ends of the bottom plate 51 are respectively placed on the two support plates 35; a positioning mechanism 41 for fixing the bottom plate 51 of the lock buckle 5 is installed at the bottom of the welding mechanism 4, and the positioning mechanism 41 is mounted above the two support plates 35.

[0037] During the actual production and processing process, after the operator assembles the retaining ring 52 on the base plate 51, the operator aligns the retaining ring 52 with the positioning groove 34 between the first clamping seat 31 and the second clamping seat 33, and places the base plate 51 on the two support plates 35; the operator controls the automatic clamping drive 32 to drive the second clamping seat 33 to slide toward the second clamping seat 33 until the retaining ring 52 is tightly pressed between the first clamping seat 31 and the second clamping seat 33; then, the operator can control the driving mechanism of the welding machine to drive the welding mechanism 4 to move down until the welding head contacts the two melting points on the lock buckle 5, and hot melt spot welding is performed on the retaining ring 52 and the base plate 51. Through the setting of the automatic clamping drive 32, the operator does not need to clamp the retaining ring 52 through the handwheel screw structure, which can effectively improve the convenience of using the welding machine and improve the efficiency of welding the lock buckle 5.

[0038] In addition, since the welding mechanism 4 is equipped with a positioning mechanism 41, the base plate 51 can be fixed during the welding process, thereby reducing the shaking and displacement of the base plate 51 and the retaining ring 52 during the welding process, thereby reducing the occurrence of affecting the welding accuracy.

[0039] Among them, the positioning grooves 34 opened on the first clamp seat 31 and the second clamp seat 33 are used to fix the upper part of the buckle 52. The first clamp seat 31 and the second clamp seat 33 respectively have half of the positioning groove 34. The complete positioning groove 34 formed by the first clamp seat 31 and the second clamp seat 33 is adapted to the upper part of the buckle 52.

[0040] Reference Figure 2 and Figure 3 A fixing block 36 is detachably mounted on the clamp 3 and is located below the first clamp seat 31 . A limiting groove 361 is provided on the side wall of the fixing block 36 close to the second clamp seat 33 and is adapted to the lower half of the buckle 52 .

[0041] The limiting groove 361 can limit the lower half of the buckle 52 to reduce the deformation of the lower half of the buckle 52 due to heat.

[0042] In some other embodiments, according to actual use needs, the fixing block 36, the first clamping seat 31 and the second clamping seat 33 can be replaced to adapt to lock buckles 5 of different models and sizes, which is not limited here.

[0043] Reference Figure 1 and Figure 2 In the embodiment of the present application, the automatic clamping drive member 32 adopts a cylinder, the cylinder body of the cylinder is fixedly installed on the clamp 3, the driving shaft of the cylinder is fixedly installed with a connecting seat 321, and the second clamping seat 33 is detachably fixedly installed on the connecting seat 321.

[0044] The cylinder can drive the second clamping seat 33 to slide toward or away from the first clamping seat 31 by extending or retracting the driving shaft, thereby achieving the technical effect of automatically clamping and releasing the lock buckle 5.

[0045] Reference Figure 1 and Figure 2 In the embodiment of the present application, the control buttons 6 for controlling the welding mechanism 4, the lifting mechanism, and the cylinder are all fixedly installed on the workbench 2, and the operator can control the operation of the welding mechanism 4, the lifting mechanism, and the cylinder respectively through the control buttons 6.

[0046] Reference Figure 2 and Figure 3A guide rail 38 is fixedly installed on the clamp 3, and a slider 322 is fixedly installed on the bottom of the connecting seat 321. The slider 322 is provided with a slide groove that is compatible with the guide rail 38; limiting protrusions are integrally formed on both sides of the guide rail 38, and limiting grooves that are compatible with the limiting protrusions are respectively provided on the opposite inner side walls of the slide groove. The two limiting protrusions are respectively embedded in the two limiting grooves.

[0047] The guide rail 38 and slider 322 work together to restrict the sliding trajectory of the connecting base 321 during its movement, effectively reducing misalignment between the first clamping base 31 and the second clamping base 33. The limiting groove and limiting protrusion prevent the slider 322 from falling off the guide rail 38, further ensuring the sliding stability of the connecting base 321 and the second clamping base 33.

[0048] Reference Figure 2 The welding mechanism 4 includes a welding seat 42, and a plurality of positioning rods 411 are slidably connected to the welding seat 42. The two ends of the plurality of positioning rods 411 are respectively fixedly connected with anti-slip blocks. The positioning rods 411 are coaxially sleeved with springs 412, and the springs 412 are tightly pressed between the welding seat 42 and the anti-slip blocks.

[0049] When the lifting mechanism drives the welding mechanism 4 to move downward, the end of the positioning rod 411 contacts the top of the base plate 51, the spring 412 is compressed, and the positioning rod 411 slides upward. The spring 412 can form a downward elastic force on the base plate 51, which can achieve a clamping and fixing effect on the base plate 51, reducing the occurrence of deviation and shaking of the base plate 51 during welding.

The two ends of the two support plates 35 are detachably connected to the top of the two vertical plates 39, and U-shaped grooves 391 are respectively opened on the two vertical plates 39.

[0051] When installing the buckle 52 and the base plate 51 , the U-shaped groove 391 allows the operator to observe the position of the buckle 52 and to fix the buckle 52 on the first clamping seat 31 and the fixing block 36 .

[0052] Among them, a space for placing the raw material boxes of the buckle 52 and the bottom plate 51 respectively is provided on the working platform beside the clamp 3, which can further improve the convenience of the operator using the welding machine to weld the lock buckle 5.

[0053] Reference Figure 1 and Figure 2A discharging slide rail 11 arranged to be inclined downward is fixedly installed on the frame 1, and a discharging port 13 for the discharging slide rail 11 to extend out is opened on the frame 1. The discharging slide rail 11 passes through the outlet and extends to the outside of the frame 1, and the entrance of the discharging slide rail 11 is opposite to the U-shaped groove 391 on the vertical plate 39.

[0054] When the lock buckle 5 is welded, the operator can control the cylinder to drive the second clamp seat 33 to slide in the direction away from the first clamp seat 31 and release the lock buckle 5. Then the user can use tools to transfer the welded lock buckle 5 through the U-shaped groove 391 to the discharge slide rail 11 and send it out, which can improve the efficiency of removing the lock buckle 5 and further improve the efficiency of welding the lock buckle 5.

[0055] Reference Figure 1 A safety grating 12 is fixedly mounted on the frame 1. By providing the safety grating 12, during the welding process of the welding mechanism 4, an automatic alarm can be sounded when the operator performs a dangerous operation, thereby improving the safety of the welding machine.

[0056] The implementation principle of a car door lock buckle welding machine in the embodiment of the present application is as follows: during the actual production and processing process, the operator assembles the buckle 52 on the base plate 51, aligns the buckle 52 with the positioning groove 34 between the first clamping seat 31 and the second clamping seat 33, and places the base plate 51 on the two support plates 35; the operator controls the automatic clamping drive member 32 to drive the second clamping seat 33 to slide in the direction close to the second clamping seat 33 until the buckle 52 is tightly pressed between the first clamping seat 31 and the second clamping seat 33; then, the operator can control the driving mechanism of the welding machine to drive the welding mechanism 4 to move downward until the welding head contacts the two melting points on the lock buckle 5, and hot melt spot welding is performed on the buckle 52 and the base plate 51. Through the setting of the automatic clamping drive member 32, the operator does not need to clamp the buckle 52 through the handwheel screw structure, which can effectively improve the convenience of using the welding machine and improve the efficiency of welding the lock buckle 5.
