Description

Technical Field

[0001] This application relates to the field of welding machines, and particularly to a clutch welding machine with high positioning accuracy. Background Art

[0002] The clutch is a commonly used component in the internal mechanical transmission of an automobile, which can separate or engage the transmission system at any time. The clutch pressure plate is an important structure on the clutch and plays an important role in the driving safety of the automobile.

[0003] In the prior art, when processing the clutch, it is necessary to fix the face plate on the pressure plate assembly of the clutch by hot melt welding through a welding machine. The common welding machines used for welding clutches mainly include a frame, on which a welding workbench and a driving mechanism are fixedly installed, and the welding mechanism of the welding machine is fixedly installed at the driving end of the driving mechanism; a servo turntable is installed on the welding workbench, and a fixture for installing the pressure plate assembly is fixedly installed on the servo turntable.

[0004] During the welding process of the pressure plate assembly, the operator assembles the face plate on the pressure plate assembly and places the pressure plate assembly on the fixture on the servo turntable. The servo turntable drives the pressure plate assembly to drive the turntable to rotate the welding points to the lower part of the welding head of the welding mechanism at set time intervals in turn, and the driving mechanism drives the welding head to move down. After the welding head contacts the face plate for a certain time, it returns.

[0005] However, in hot melt welding processing, the welding head needs to apply a certain pressure to the face plate. The existing servo turntable fixture cannot stably fix the pressure plate assembly on the servo turntable, which easily causes the pressure plate to tilt and shake during the welding process, resulting in low stability and there is room for improvement. Utility Model Content

[0006] In order to improve the stability of the fixture during the welding process of the face plate and the pressure plate assembly of the welding machine and ensure the welding effect of the welding machine, this application provides a clutch welding machine with high positioning accuracy.

[0007] The clutch welding machine with high positioning accuracy provided by this application adopts the following technical solutions:

[0008] A clutch welding machine with high positioning accuracy includes a frame, on which a workbench is fixedly installed, a servo turntable is installed on the workbench, and a positioning tooling for fixing the pressure plate assembly is fixedly installed on the servo turntable;

[0009] A clamping driving mechanism is fixedly installed on the frame. An installation seat is fixedly installed at the driving end of the clamping driving mechanism. A clamping seat is rotatably installed on the installation seat. The clamping seat is erected above the servo turntable. A plurality of clamping blocks are fixedly installed at the bottom of the clamping seat. The clamping driving mechanism drives the plurality of clamping blocks to move towards or away from the workbench;

[0010] A locking mechanism for locking or releasing the clamping seat is fixedly installed on the installation seat.

[0011] By adopting the above technical solution, during the actual welding process, after the operator assembles the face plate to be welded on the chuck assembly, the face plate and the chuck assembly are placed on the positioning fixture on the servo turntable; then the clamping driving mechanism drives the installation seat to move downwards, so that the clamping blocks at the bottom of the clamping seat are clamped and fixed on the top of the face plate, making the face plate and the chuck assembly tightly pressed between the positioning fixture on the servo turntable and the clamping seat. Then the locking mechanism locks the clamping seat to facilitate the welding head of the welding mechanism to weld the face plate and the chuck. This prevents the clamping seat from shifting during the welding process of the welding head; when the welding head completes the welding of one solder joint, the locking mechanism releases the clamping seat, and the servo turntable drives the chuck assembly to rotate until the next solder joint is directly below the welding head, and the locking mechanism relocks the clamping seat. By the combined use of the clamping driving mechanism, the clamping seat and the locking mechanism, the face plate and the chuck assembly can be stably and effectively fixed during the welding process of the welding head to the chuck, reducing the occurrence of displacement and inclination of the face plate and the chuck assembly during the welding process of the welding head, providing an effective guarantee for the welding effect of the welding machine.

[0012] Preferably, the clamping driving mechanism includes a first cylinder. The cylinder body of the first cylinder is fixedly installed on the frame, and the cylinder shaft of the first cylinder is fixedly connected to the top of the installation seat.

[0013] By adopting the above technical solution, when the first cylinder extends or retracts the cylinder shaft, the technical effect of driving the installation seat and the clamping seat to move up and down can be achieved.

[0014] Preferably, a rotating shaft rod is rotatably installed at the bottom of the installation seat, and the bottom of the rotating shaft rod is fixedly connected to the top of the clamping seat;

[0015] A protective cover cylinder is fixedly connected to the bottom of the installation seat, and the protective cover cylinder is coaxially sleeved outside the rotating shaft rod.

[0016] By adopting the above technical solution, the technical effect of rotatably connecting the clamping seat and the installation seat can be achieved through the rotating shaft rod, and the protective cover cylinder can provide effective protection for the rotating shaft rod.

[0017] Preferably, the locking mechanism includes a second cylinder, the cylinder block of the second cylinder is fixedly installed on the mounting seat, and a locking rod is fixedly installed at the cylinder shaft end of the second cylinder;

[0018] A number of locking holes adapted to the locking rod are formed on the clamping seat.

[0019] By adopting the above technical solution, when the servo turntable drives the pressure plate assembly to rotate so that the solder joint is located below the welding head of the welding mechanism, the second cylinder extends the cylinder shaft so that the locking rod extends into the locking hole, restricting the positions of the clamping seat and the clamping block, and reducing the occurrence of the pressure plate assembly shifting due to the rotation of the clamping seat and the clamping block.

[0020] Preferably, a limiting block is fixedly installed on the outer side wall of the protective cover cylinder, a limiting hole is formed through the limiting block, and the locking rod is slidably arranged in the limiting hole.

[0021] By adopting the above technical solution, the limiting hole on the limiting block can restrict the sliding trajectory of the locking rod, reducing the occurrence of the locking rod skewing and being misaligned with the locking rod on the clamping plate.

[0022] Preferably, the bottom end of the locking rod is arranged in an inverted conical shape.

[0023] By adopting the above technical solution, the inverted conical setting of the bottom end of the locking rod can reduce the occurrence of the locking rod colliding with the locking hole.

[0024] In summary, the clutch welding machine with high positioning accuracy of the present application includes at least one of the following beneficial technical effects:

[0025] 1. By using the clamping driving mechanism, the clamping seat and the locking mechanism in combination, the face plate and the pressure plate assembly can be stably and effectively fixed during the welding process of the welding head welding the pressure plate, reducing the occurrence of the face plate and the pressure plate assembly shifting and tilting during the welding process of the welding head, providing an effective guarantee for the welding effect of the welding machine;

[0026] 2. The limiting hole on the limiting block can restrict the sliding trajectory of the locking rod, reducing the occurrence of the locking rod skewing and being misaligned with the locking rod on the clamping plate. Description of the Drawings

[0031] The following further describes the present application in detail with reference to the Figures 1-3 drawings.

[0032] Embodiment

[0033] An embodiment of the present application discloses a clutch welding machine with high positioning accuracy. Referring to Figure 1 、 Figure 2 and Figure 3 , it includes a frame 1, a workbench 2 is fixedly installed on the frame 1, a servo turntable 3 is installed on the workbench 2, and a positioning tooling 31 for fixing the chuck assembly 4 is fixedly installed on the servo turntable 3; a clamping drive mechanism 5 is fixedly installed on the frame 1, a mounting seat 51 is fixedly installed at the driving end of the clamping drive mechanism 5, a clamping seat 52 is rotatably installed on the mounting seat 51, the clamping seat 52 is arranged above the servo turntable 3, a plurality of clamping blocks 53 are fixedly installed at the bottom of the clamping seat 52, and the clamping drive mechanism 5 drives the plurality of clamping blocks 53 to move towards or away from the workbench 2; a locking mechanism 6 for locking or releasing the clamping seat 52 is fixedly installed on the mounting seat 51.

[0034] During the actual welding process, after the operator assembles the face plate 41 to be welded on the chuck assembly 4, the face plate 41 and the chuck assembly 4 are placed on the positioning tooling 31 on the servo turntable 3; then the clamping drive mechanism 5 drives the mounting seat 51 to move downward, so that the clamping blocks 53 at the bottom of the clamping seat 52 clamp and fix the top of the face plate 41, so that the face plate 41 and the chuck assembly 4 are pressed tightly between the positioning tooling 31 on the servo turntable 3 and the clamping seat 52. Then the locking mechanism 6 locks the clamping seat 52, so as to facilitate the welding head 71 of the welding mechanism 7 to weld the face plate 41 and the chuck, and prevent the clamping seat 52 from shifting during the welding process of the welding head 71; when the welding head 71 completes the welding of one welding point, the locking mechanism 6 releases the clamping seat 52, and the servo turntable 3 drives the chuck assembly 4 to rotate until the next welding point is directly below the welding head 71, and the locking mechanism 6 locks the clamping seat 52 again.

[0035] By the combined use of the clamping drive mechanism 5, the clamping seat 52 and the locking mechanism 6, the face plate 41 and the chuck assembly 4 can be stably and effectively fixed during the welding process of the welding head 71 to the chuck, reducing the occurrence of displacement and tilt of the face plate 41 and the chuck assembly 4 during the welding process of the welding head 71, providing an effective guarantee for the welding effect of the welding machine.

[0036] It should be noted that in the embodiment of the present application, there are a total of 12 welding points between the face plate 41 and the chuck assembly 4. During the actual welding process, the servo turntable 3 drives the chuck assembly 4 and the face plate 41 to rotate 12 times so that the 12 welding points pass under the welding head 71 of the welding mechanism 7 in sequence. When the chuck assembly 4 and the workbench 2 stop, the locking mechanism 6 locks the clamping seat 52 to prevent the clamping seat 52 from rotating due to inertia and affecting the positions of the chuck assembly 4 and the face plate 41.

[0037] In the embodiment of the present application, the clamping drive mechanism 5 uses a first cylinder 54. The cylinder body of the first cylinder 54 is fixedly installed on the frame 1, and the cylinder shaft of the first cylinder 54 is fixedly connected to the top of the mounting seat 51.

[0038] When the first cylinder 54 extends or retracts its cylinder shaft, the technical effect of driving the mounting seat 51 and the clamping seat 52 to move up and down can be achieved.

[0039] Refer to Figure 1 And Figure 2 , a rotating shaft rod 55 is rotatably installed at the bottom of the mounting seat 51, and the bottom of the rotating shaft rod 55 is fixedly connected to the top of the clamping seat 52; a protective cover cylinder 56 is fixedly connected to the bottom of the mounting seat 51, and the protective cover cylinder 56 is coaxially sleeved outside the rotating shaft rod 55.

[0040] The technical effect of rotatably connecting the clamping seat 52 and the mounting seat 51 can be achieved through the rotating shaft rod 55, and the protective cover cylinder 56 can provide effective protection for the rotating shaft rod 55.

[0041] Refer to Figure 1 , Figure 2 And Figure 3 , in the embodiment of the present application, the locking mechanism 6 uses a second cylinder 61. The cylinder body of the second cylinder 61 is fixedly installed on the mounting seat 51, and a locking rod 62 is fixedly installed at the cylinder shaft end of the second cylinder 61; a number of locking holes 521 adapted to the locking rod 62 are provided on the clamping seat 52.

[0042] When the servo turntable 3 drives the pressure plate assembly 4 to rotate so that the welding point is located below the welding head 71 of the welding mechanism 7, the second cylinder 61 extends the cylinder shaft so that the locking rod 62 extends into the locking hole 521, restricting the positions of the clamping seat 52 and the clamping block 53, and reducing the occurrence of the pressure plate assembly 4 shifting due to the rotation of the clamping seat 52 and the clamping block 53.

[0043] It should be noted that in some other embodiments, according to the actual usage requirements, the first cylinder 54 and the second cylinder 61 can be replaced with electric telescopic cylinders, motor screw structures, etc., which are not limited herein.

[0044] Refer to Figure 2 With Figure 3 , a limit block 57 is fixedly installed on the outer side wall of the protective cover cylinder 56, and a limit hole is penetrated through the limit block 57. The locking rod 62 is slidably arranged in the limit hole. The limit hole on the limit block 57 can restrict the sliding trajectory of the locking rod 62, reducing the occurrence of the locking rod 62 skewing and being misaligned with the locking rod 62 on the clamping plate.

[0045] Refer to Figure 1 With Figure 2 , the bottom end of the locking rod 62 is arranged in an inverted conical shape. The inverted conical setting of the bottom end of the locking rod 62 can reduce the occurrence of the locking rod 62 colliding with the locking hole 521.

[0046] The implementation principle of a clutch welding machine with high positioning accuracy in this application embodiment is as follows: During the actual welding process, after the operator assembles the face plate 41 to be welded on the pressure plate assembly 4, the face plate 41 and the pressure plate assembly 4 are placed on the positioning tooling 31 on the servo turntable 3; subsequently, the clamping and driving mechanism 5 drives the mounting seat 51 to move downward, so that the clamping block 53 at the bottom of the clamping seat 52 clamps and fixes the top of the face plate 41, making the face plate 41 and the pressure plate assembly 4 tightly pressed between the positioning tooling 31 on the servo turntable 3 and the clamping seat 52. Subsequently, the locking mechanism 6 locks the clamping seat 52, facilitating the welding head 71 of the welding mechanism 7 to weld the face plate 41 and the pressure plate, and preventing the clamping seat 52 from shifting during the welding process of the welding head 71; when the welding head 71 completes the welding of one welding point, the locking mechanism 6 releases the clamping seat 52, and the servo turntable 3 drives the pressure plate assembly 4 to rotate until the next welding point is directly below the welding head 71, and the locking mechanism 6 re-locks the clamping seat 52. By the combined use of the clamping and driving mechanism 5, the clamping seat 52 and the locking mechanism 6, the face plate 41 and the pressure plate assembly 4 can be stably and effectively fixed during the welding process of the welding head 71, reducing the occurrence of the face plate 41 and the pressure plate assembly 4 shifting and tilting during the welding process of the welding head 71, providing an effective guarantee for the welding effect of the welding machine.

[0047] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
