Description

Technical Field

[0001] This utility model relates to the technical field of quick-change fixture devices, specifically a quick-change fixture device for a welding workstation. Background Technology

[0002] A welding workstation is a specialized welding operation platform that integrates welding equipment, tooling fixtures, control systems, and auxiliary devices. It is widely used in industrial fields such as automobile manufacturing, aerospace, electronics, and machining.

[0003] Welding workstations need to weld various types of parts during daily production. Therefore, the base of the welding workstation needs to be compatible with different fixtures. When producing different parts, the parts can be clamped and welded by quickly changing the corresponding fixture. Currently, the quick-change method between the base and the fixture usually involves setting multiple cylinders on the base. The cylinders push pins to push or pull the pins into or out of the corresponding pin slots on the fixture, thus achieving quick change between the fixture and the base. However, this quick-change structure requires multiple cylinders on the base, which takes up more space, especially in compact equipment layouts. The control system is also more complex, and the programming logic needs to consider the coordination of each cylinder. Furthermore, the procurement cost of multiple cylinders and accessories is higher, the consumption of compressed air during use is greater, and the long-term energy cost is higher.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a quick-change device for a welding workstation clamp, including a base 1 fixed on the ground, a support plate 2 on the base 1, a space between the base 1 and the support plate 2, a lifting chamber 3 on the support plate 2, a locking mechanism 4 that can be raised and lowered in the lifting chamber 3, a drive mechanism 5 on the base 1 that can drive the locking mechanism 4 to move up and down, and a locking mechanism 6 on the lifting chamber 3 that can fix the locking mechanism 4 after it has risen. By driving the locking mechanism 4 to rise or fall in the lifting chamber 3 through the drive mechanism 5, the clamp can be fixed and unlocked, and when the clamp is fixed, the locking mechanism 6 can lock the locking mechanism 4 after it has risen.

[0023] The locking mechanism 6 includes a second cylinder 61. The second cylinder 61 is installed on the lifting chamber 3. The output end of the second cylinder 61 is fixedly connected to a connecting seat rod 62. Both ends of the connecting seat rod 62 are connected to locking seats 63. The locking seat 63 is provided with a locking groove 64 and a guide rod 65. An insert layer is provided between the top of the locking seat 63 and the locking groove 64.

[0024] The drive mechanism 5 includes a first cylinder 51, a fabric box 7 fixedly connected to the base 1, a sleeve frame symmetrically fixedly connected to both sides inside the fabric box 7, a first connecting rod 53 slidably connected inside the sleeve frame, a first push post 54 fixedly connected to one end of the first connecting rod 53, and a second slide groove 58 provided at the other end of the first connecting rod 53. The first cylinder 51 is installed on the base 1, and a push plate 52 is fixedly connected to the output end of the first cylinder 51 through the fabric box 7. A second push post 59 is fixedly connected to the push plate 52, and the second push post 59 is slidably connected to the second slide groove 58. A second connecting rod 55 is movably arranged in the fabric box 7. The second connecting rod 55 will be inserted into the space left between the base 1 and the support plate 2. A first slide groove 56 that cooperates with the first push post 54 is opened at one end of the second connecting rod 55. A top block 57 is fixedly connected to the top of the second connecting rod 55, and the top block 57 is slidably connected to the bottom of the inner compartment of the lifting chamber 3.

[0025] It is worth mentioning that the first cylinder 51, as the driving source, needs to be matched with a suitable model according to the normal operation requirements of the locking mechanism 4.

[0026] The locking mechanism 4 includes a lifting column 41. A mounting base 11 is fixedly connected to the lifting chamber 3. The lifting column 41 is slidably connected to the mounting base 11. A fixing plate 46 is fixedly connected to the lifting column 41. A first spring 47 is installed on the outside of the lifting column 41 between the fixing plate 46 and the mounting base 11. A positioning plate 43 and a pin block 42 are arranged sequentially from bottom to top on the outside of the lifting column 41. A positioning gap 45 is formed between the positioning plate 43 and the pin block 42. A guide groove 44 is opened on the lifting column 41. When the second cylinder 61 drives the locking seat 63 to move in the locking state, the locking seat 63 will drive the guide rod 65 to insert into the guide groove 44. Simultaneously, the insert layer will be inserted into the positioning gap 45, the positioning plate 43 will be inserted into the locking groove 64, and the pin block 42 will be supported on the top of the locking seat 63, thereby realizing the locking of the lifting column 41.

[0027] The fixture is provided with a pin groove that matches the pin block 42. When the pin block 42 rises, it can be inserted into the pin groove to fix the fixture. When the pin block 42 falls, it can be disengaged from the pin groove to unlock the fixture.

[0028] It is worth mentioning that when the locking seat 63 retracts, it will cause the guide rod 65 to completely disengage from the inside of the guide groove 44, without affecting the descent of the lifting column 41.

[0029] Among them, guide bars 9 are fixedly connected to the top two sides of the mounting base 11, and the locking base 63 is slidably connected to the two guide bars 9.

[0030] The top of the fabric box 7 is detachably equipped with a cover plate 8. With the cooperation of the fabric box 7 and the cover plate 8, the drive mechanism 5 can be uniformly integrated and protected, reducing the entry of dust.

[0031] The lifting chamber 3 is equipped with a buffer 10 that can protect the clamp during loading. After the clamp is pushed into the base 1, the positioning part on the clamp will move continuously with the clamp until it comes into contact with the buffer 10.

[0032] Specific working principle:

[0033] When the fixture on the base 1 needs to be replaced, the output end of the second cylinder 61 can be driven to pull the connecting rod 62 to move. Then the connecting rod 62 will drive the locking seat 63 to move. The insert layer and the locking groove 64 will separate from the positioning gap 45 and the positioning plate 43 respectively. At the same time, the guide rod 65 slides backward in the guide groove 44. At this time, the locking seat 63 releases the locking of the lifting column 41.

[0034] Then, the first cylinder 51 is driven to work, causing the output end of the first cylinder 51 to pull the push plate 52 to move. Then, the second push column 59 will squeeze the inner wall of the second slide groove 58, causing the first connecting rod 53 to move towards the middle of the push plate 52. Simultaneously, the first push column 54 will squeeze the groove wall of the first slide groove 56, causing the second connecting rod 55 to drive the top block 57 to slide deeper into the space between the base 1 and the support plate 2. The top block 57 will move away from the lifting column 41 and no longer support the lifting column 41. The fixing plate 46 will drive the lifting column 41 to move downward under the elastic force of the first spring 47, causing the pin block 42 to disengage from the pin groove on the fixture. Then, the fixture can be pushed out for replacement.
