Technical Field

[0001] This utility model relates to the field of hydraulic equipment technology, specifically to a hydraulic center frame mechanism with brake. Background Technology

[0002] The center rest is one of the main accessories for lathes. It is an indispensable device for turning slender shafts and tubes. Its main function is to provide auxiliary support and enhance rigidity when turning slender shafts and tubes, and to reduce vibration or bending deformation of the workpiece during the turning process.

[0023] Please see Figures 1-7 A hydraulic center frame mechanism with brake includes two linear guide rails 1 and a workpiece 7. Clamping devices 2 and sliders 3 are slidably sleeved on the upper surfaces of the two linear guide rails 1. A first base 5 is fixedly installed on the upper surfaces of the two clamping devices 2 and sliders 3. A third fixing bolt 15 is threadedly connected between the first base 5 and the two clamping devices 2. A first fixing bolt 4 is threadedly connected between the first base 5 and the two sliders 3. A control device 14 is fixedly installed on the upper surface of the first base 5. Multiple reinforcing brackets 18 are fixedly installed between the control device 14 and the first base 5. A hydraulic center frame base 9 is fixedly installed on one side of the control device 14. Two second clamping mechanisms 11 and a first clamping mechanism 10 are fixedly installed on the front surface of the hydraulic center frame base 9. A clamping sleeve mechanism 6 is fixedly installed on the front surface of each of the two second clamping mechanisms 11. Multiple fixing parts 12 are fixedly installed between the control device 14 and the hydraulic center frame base 9. Two second fixing bolts 13 are threadedly connected to the upper surfaces of each of the multiple fixing parts 12.

[0024] In the above structure, the hydraulic center frame can slide along the linear guide rail 1 via the slider 3, and the clamp 2 can automatically lock after the hydraulic center frame moves to the designated position, thereby improving the automation level of the equipment. The first clamping mechanism 10 and the second clamping mechanism 11 are used to clamp the workpiece 7, which facilitates the processing of the workpiece 7. The clamping sleeve mechanism 6 is installed at the front end of the second clamping mechanism 11 to protect the workpiece 7 and prevent it from being damaged during the clamping process.

[0025] In a preferred embodiment, a drive motor 16 is fixedly mounted on the rear end face of the control device 14, a gear 17 is fixedly mounted on the output end of the drive motor 16, and a rack 8 is fixedly mounted on one side of the gear 17, with the rack 8 and the gear 17 meshing with each other.

[0026] In the above structure, the rack 8 and the gear 17 mesh with each other, and the drive motor 16 drives the gear 17 to rotate, thereby driving the hydraulic center frame to slide along the linear guide rail 1.

[0027] In a preferred embodiment, the clamping sleeve mechanism 6 includes a clamping sleeve body 601, an elastic block 602 is fixedly installed on the lower end face of the clamping sleeve body 601, and a No. 1 internal hex bolt 603 is threadedly connected to the upper end face of the clamping sleeve body 601.

[0028] In the above structure, the clamping sleeve mechanism 6 is installed and fixed to the front end of the second clamping mechanism 11 by the first hex socket bolt 603. The elastic block 602 set at the lower end of the clamping sleeve body 601 can protect the workpiece 7 and effectively prevent the workpiece 7 from being scratched during the clamping process, thus affecting the product quality.

[0029] In a preferred embodiment, the first clamping mechanism 10 includes a hydraulic rod 1001, a second base 1002 is fixedly installed on the front end face of the hydraulic rod 1001, a first clamping member 1003 is fixedly installed on the front end face of the second base 1002, and a fourth fixing bolt 1004 is threadedly connected between the first clamping member 1003 and the second base 1002.

[0030] In the above structure, the hydraulic rod 1001 is extended and retracted to push the first clamping member 1003 forward, which, together with the second clamping mechanism 11, can firmly fix the workpiece 7. At the same time, the first clamping member 1003 also has a certain elasticity, which can protect the workpiece 7.

[0031] In a preferred embodiment, the second clamping mechanism 11 includes two limiting blocks 1103, a rotating shaft 1104 is fixedly installed between the two limiting blocks 1103, a second clamping member 1101 is rotatably connected to the outside of the rotating shaft 1104, and a screw hole 1102 is opened on the upper end face of the second clamping member 1101.

[0032] In the above structure, the workpiece 7 can be clamped by rotating the second clamping member 1101 around the rotating shaft 1104, and the screw hole 1102 cooperates with the first internal hex bolt 603 to fix the clamping sleeve mechanism 6 to the front end of the second clamping mechanism 11.

[0033] The working principle is as follows: the automatic locking clamp 2 is connected and locked to the hydraulic center frame. The locking and unlocking states of the clamp 2 are controlled by electrical control. The hydraulic center frame uses a high-precision linear guide as the motion guide and is driven by a high-precision gear 17 rack 8. After the hydraulic center frame moves to the designated position, the clamp 2 will automatically lock, thereby braking the hydraulic center frame.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
