DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 , a clamping flange broach fixing device comprises a base 1, a rotating shaft 2 is rotatably installed on the upper end surface of the base 1, a connecting plate 3 is fixedly installed on the end of the rotating shaft 2, and the bottom wall of the connecting plate 3 is fixedly connected to two sliding blocks 5 through a reinforcing mechanism. The reinforcing mechanism comprises a reinforcing rod 4 fixedly installed on the bottom wall of the connecting plate 3, and the end of the reinforcing rod 4 is fixedly connected to the upper end surface of the sliding block 5. The upper end surface of the base 1 is provided with a sliding groove matching the two sliding blocks 5. A first fixed frame 6 and a second fixed frame 7 are fixedly installed on the upper end surface of the connecting plate 3. A double-headed screw 8 is rotatably installed inside the first fixed frame 6, and a motor 9 connected to the double-headed screw 8 is fixedly installed on the outer wall of the first fixed frame 6. Two moving sleeves 11 are threadedly installed on the outer wall of the double-headed screw 8 through a limiting mechanism. The limiting mechanism comprises a limiting rod 10 fixedly installed inside the first fixed frame 6, and the limiting rod 10 slides through the two moving sleeves 11. The limiting rod 10 can limit the two moving sleeves 11 so that the two moving sleeves 11 can only move axially along the outer wall of the double-headed screw 8.

[0023] The upper end surfaces of the two movable sleeves 11 are fixedly installed with connecting sleeves 13 through movable plates 12, and connecting rods 14 are slidably installed inside the two connecting sleeves 13. Fixed pins 15 are slidably installed on the outer walls of the two connecting sleeves 13. The outer walls of the two connecting rods 14 are provided with fixing holes that cooperate with the fixing pins 15. The ends of the two fixing pins 15 are fixedly installed with shift blocks 16. The bottom walls of the two shift blocks 16 are connected to the outer wall of the connecting sleeve 13 on the same side through a fixing mechanism. The fixing mechanism includes a fixing spring 17 fixedly installed on the outer wall of the fixing pin 15, and the two ends of the fixing spring 17 are elastically connected to the outer wall of the connecting sleeve 13 and the bottom wall of the shift block 16 respectively.

[0024] The ends of the two connecting rods 14 are fixedly installed with clamping blocks 18, and the inner wall of one side of the second fixed frame 7 is fixedly connected to the fixing plate 20 through a supporting mechanism. The supporting mechanism includes a supporting rod 19 fixedly installed on the inner wall of the second fixed frame 7, and the end of the supporting rod 19 is fixedly connected to the outer wall of the fixing plate 20, and the outer wall of the fixing plate 20 is fixedly installed with an insertion rod 21. The inner wall of the other side of the second fixed frame 7 is fixedly connected to a clamping plate 23 through a telescopic mechanism. The telescopic mechanism includes a row of electric push rods 22 fixedly installed inside the second fixed frame 7, and the telescopic end of the electric push rod 22 is fixedly connected to the outer wall of the clamping plate 23. The inner wall of the clamping plate 23 is provided with a socket that cooperates with the insertion rod 21. The clamping plate 23 and the inner wall of the fixing plate 20 are both installed with anti-slip pads 24. The anti-slip bottom 24 is made of rubber material. The rubber material has good elasticity and softness, which enables it to form a closer contact between the surface and the object, thereby increasing friction and improving the friction coefficient.

[0025] When the utility model is used, the connecting plate 3 can be rotated according to the broach used. When the inner broach needs to be used, the first fixed frame 6 can be rotated to the center position of the base 1 by the cooperation of the rotating shaft 2 and the connecting plate 3. When the connecting plate 3 is rotated, the sliding block 5 can be driven to slide in the sliding groove through the reinforcing rod 4, and then the end of the inner broach can be placed between the two clamping blocks 18. Then the motor 9 drives the double-headed screw 8 to rotate, and the double-headed screw 8 drives the two movable sleeves 11 to move through the limit rod 10, so that the two clamping blocks 18 can be close to each other to clamp and fix the end of the inner broach. When it is necessary to clamp and fix inner broaches of different sizes, the block 16 can be moved to drive the fixing pin 15 to move out of the fixing hole, thereby releasing the fixation of the connecting rod 14, and then the connecting rod 14 can be moved out of the connecting sleeve 13, so that the clamping blocks 18 of different sizes can be replaced;

[0026] When the external broach needs to be clamped, the second fixing frame 7 can be rotated to the center of the base 1, and then the connecting hole at the end of the external broach can be sleeved on the outer wall of the insertion rod 21, and then the electric push rod 22 drives the clamping plate 23 to move, and drives the insertion hole to move on the outer wall of the insertion rod 21, so that the clamping plate 23 and the fixing plate 20 can be close to each other, and the end of the external broach can be clamped and fixed by the anti-slip pad 24. The anti-slip pad 24 increases the friction between the end of the external broach, thereby improving the firmness of the clamping. When broaching, the cooperation between the reinforcement rod 4 and the slider 5 can increase the deformation resistance of the connecting plate 3, and avoid deformation and damage of the connecting plate 3 due to strong pulling force.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
