[0003] For the hot forging and forming of the knuckle, a robot is required to first put a round steel into a forging press for forging and then take it out after completion. Since the shapes of the forgings before and after are greatly changed, in order to avoid using different fixtures to clamp the forgings before and after and improve the working efficiency, a fixture that can meet the clamping of the round steel and the knuckle forging is needed. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a special fixture for hot forging of a knuckle for a robot, which has the effect of improving the working efficiency.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions: it includes a main body block and first fixing blocks symmetrically and hingedly arranged on the main body block. A detachable clamping block is arranged on the first fixing block. A driving mechanism for driving the two first fixing blocks to approach or separate from each other is arranged on the main body block. A first clamping part for clamping the round steel is arranged on the clamping block, and a second clamping part for fixing the forging is arranged on the clamping block.
[0006] The further setting of the utility model is: the driving mechanism includes a driving cylinder arranged on the main body block and a driving rod arranged at the output end of the driving cylinder. A second fixing block is arranged at the end of the driving rod. Third fixing blocks are symmetrically and hingedly arranged on the second fixing block. The third fixing block is hinged to the end of the adjacent first fixing block.

[0015] The beneficial effects of the present utility model are:
[0016] 1. By setting the first clamping part and the second clamping part, when it is necessary to clamp the round steel for forging, the first clamping part can be directly used to clamp the round steel. When it is necessary to clamp the forging after forging, the second clamping part can be used to clamp the forging, so as to meet the needs of clamping the round steel and the steering knuckle forging, avoid the need to replace different jigs to clamp the round steel and the forging respectively, and achieve the purpose of improving work efficiency.
[0017] 2. By setting up a driving cylinder, a driving rod, etc., when it is necessary to clamp a round steel or a forging, first align the clamping blocks of the fixture with the workpiece, and then turn on the driving cylinder. The driving cylinder drives the driving rod to move in the direction close to the clamping blocks. Through the second fixing block, the two third fixing blocks are driven to rotate, so that the distance between the ends of the two third fixing blocks close to the first fixing block increases, thereby pushing the distance between the ends of the two first fixing blocks close to the third fixing block to increase. Since the middle of the first fixing block is hinged to the main body block, forming a structure similar to a scissors type, when the distance between the ends of the two first fixing blocks close to the third fixing block increases, the distance between the ends of the two first fixing blocks close to the clamping blocks decreases instead, so that the two clamping blocks approach each other and clamp the round steel or the forging. The clamping of the round steel or the forging is realized through the driving rod, the second fixing block, etc., and the structure is simple and the operation is convenient.
[0018] 3. By setting up detachable clamping blocks, when the clamping blocks are worn and need to be replaced, the connection between the clamping blocks and the first fixing blocks can be directly disconnected for replacement, avoiding replacing the entire fixture and achieving the purpose of saving production costs.

A first clamping part 5 for clamping the round steel 15 is arranged on the clamping block 3, and a second clamping part 6 for fixing the forging 16 is arranged on the clamping block 3.
[0028] A further setting of the present utility model is that the driving mechanism 4 includes a driving cylinder 4a arranged on the main body block 1 and a driving rod 4b arranged at the output end of the driving cylinder 4a. A second fixing block 7 is arranged at the end of the driving rod 4b. Third fixing blocks 8 are symmetrically and hingedly arranged on the second fixing block 7. The third fixing block 8 is hinged to the end of the adjacent first fixing block 2. When the driving rod 4b moves in the direction close to the clamping block 3, the third fixing block 8 can drive the two first fixing blocks 2 to approach each other.
[0029] A further setting of the present utility model is that the first clamping part 5 is an arc-shaped groove opened on one side of the clamping block 3, and the round steel 15 can be movably attached to the inner wall of the first clamping part 5.
[0030] A further setting of the present utility model is that a serrated connecting part 9 is arranged on the inner wall of the first clamping part 5, and the round steel 15 can be movably attached to the connecting part 9.
[0031] A further setting of the present utility model is as follows: The second clamping portion 6 is an arc-shaped groove formed on one side of the clamping block 3. The second clamping portion 6 is located in the middle of the first clamping portion 5, and one end of the forging 16 can be movably attached to the inner wall of the second clamping portion 6.
[0032] A further setting of the present utility model is as follows: A plurality of connecting rods 10 are threadedly connected to one side of the first fixing block 2. A plurality of connection holes 11 corresponding to the connecting rods 10 one by one are provided on the side of the clamping block 3 away from the first clamping portion 5, and the connecting rods 10 can be threadedly connected to the connection holes 11.
[0033] A further setting of the present utility model is as follows: An L-shaped limiting groove 12 is formed at one end of the first fixing block 2, and the clamping block 3 can be movably attached to the inner wall of the limiting groove 12.
[0034] A further setting of the present utility model is as follows: A long strip-shaped fixing groove 13 is formed on the side of the clamping block 3 away from the first clamping portion 5, and one end of the first fixing block 2 can be engaged with the fixing groove 13.
[0035] A further setting of the present utility model is as follows: A limiting block 14 is provided on the main body block 1, and the driving rod 4b movably passes through the limiting block 14.
[0036] A further setting of the present utility model is as follows: The second fixing block 7 can abut against the limiting block 14. When the second fixing block 7 abuts against the limiting block 14, a set distance is provided between two adjacent clamping blocks 3.
[0037] When it is necessary to clamp the round steel 15 or the forging 16, first align the clamping block 3 of the fixture with the workpiece, and then open the driving cylinder 4a. The driving cylinder 4a drives the driving rod 4b to move in the direction close to the clamping block 3. Through the second fixing block 7, the two third fixing blocks 8 are driven to rotate, so that the distance between the ends of the two third fixing blocks 8 close to the first fixing block 2 increases, thereby pushing the distance between the ends of the two first fixing blocks 2 close to the third fixing block 8 to increase. Since the middle of the first fixing block 2 is hinged to the main body block 1, forming a structure similar to a scissors type, when the distance between the ends of the two first fixing blocks 2 close to the third fixing block 8 increases, the distance between the ends of the two first fixing blocks 2 close to the clamping block 3 decreases instead, so that the two clamping blocks 3 approach each other and clamp the round steel 15 or the forging 16; when it is necessary to clamp the round steel 15 for forging, the two serrated connecting parts 9 clamp the round steel 15. When it is necessary to clamp the forging 16 after forging, the second clamping part 6 can be used to align with the forging 16 for clamping, so as to meet the requirements of clamping the round steel 15 and the steering knuckle forging 16, avoiding the need to replace different fixtures to clamp the round steel 15 and the forging 16 respectively, and achieving the purpose of improving work efficiency; the clamping of the round steel 15 or the forging 16 is realized through the driving rod 4b, the second fixing block 7, etc., and the structure is simple and the operation is convenient.
[0038] By setting the detachable clamping block 3, when the clamping block 3 is worn and needs to be replaced, the connection between the clamping block 3 and the first fixing block 2 can be directly disconnected for replacement, avoiding replacing the entire fixture and achieving the purpose of saving production costs.
[0039] By setting the connecting rod 10 and the connecting hole 11, when the clamping block 3 is worn and needs to be replaced, the connecting rod 10 can be directly rotated to separate the connecting rod 10 from the connecting hole 11, and the operation is simple and convenient.
[0040] By setting the serrated connecting part 9, the clamping effect of the first clamping part 5 on the round steel 15 is increased, ensuring that the first clamping part 5 can clamp the round steel 15 with a relatively smooth outer wall.
[0041] By setting the limiting groove 12 and the fixing groove 13, the contact area between the clamping block 3 and the first fixing block 2 is increased, thereby ensuring the fixing effect of the clamping block 3 on the first fixing block 2.
[0042] By setting the limiting block 14, the driving rod 4b is limited, and at the same time, the connection between the driving rod 4b and the main body block 1 is increased, so that the driving rod 4b can stably push the second fixing block 7, realize the closing and opening of the two clamping blocks 3, and realize the clamping of the round steel 15 and the forging 16.
[0043] It should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.
