Description

Technical Field

[0001] The utility model relates to the technical field of clampers, in particular to a clamper with a rotating guide device. Background Art

[0002] A gripper is a device that holds an object and manipulates it. It can clamp and release an object while performing certain actions. Sports equipment often imitates the movement of the human body. In the case of a gripper, it imitates the movement of fingers. The "fingers" themselves do not belong to the gripper. They are just special customized tools for clamping objects, called "grips." Drill rods are required for drilling work. When the drill rod rotates, a gripper is required to clamp it. However, when the existing gripper clamps the drill rod, the outer wall of the drill rod will wear when the drill rod rotates, which affects the service life of the drill rod. Therefore, we propose a gripper with a rotating guide device. Utility Model Content

[0005] Furthermore, the bushing is connected to the upper seat through a first hexagon socket head screw and a first spring washer.

[0006] Furthermore, the skeleton oil seal is connected to the bottom of the middle ring through a second hexagon socket head screw and a second spring washer.

[0007] Furthermore, the clamping cylinder is fixed to the clamp housing by a third hexagon socket head screw and a fourth spring washer.

[0008] Furthermore, the upper seat, the middle ring, the lower seat and the bearing form a rotating body.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the clamping cylinder of the utility model pushes the slip seat and the slip to move inwards through hydraulic power, clamps the internal drill rod to prevent it from falling, the upper seat, the middle ring, the lower seat and the bearing form a rotating body, the bushing will rotate with the drill rod, reducing friction, protecting the outer wall of the drill rod from wear, and increasing the service life of the drill rod.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] Embodiment 1:

[0016] See also Figure 1-3The utility model provides a technical solution: a clamp with a rotary guide device, including a clamp housing 1 and a drill rod 20, wherein two groups of clamping cylinders 2 are arranged in the clamp housing 1, and the clamping cylinders 2 are fixed to the clamp housing 1 by a third hexagon socket head screw 17 and a fourth spring washer 18, one end of the two groups of clamping cylinders 2 are provided with a slip seat 3, and the opposite side walls of the two groups of slip seats 3 are provided with slips 4, and the drill rod 20 is located between the opposite side walls of the two groups of slips 4, and the tops of the two groups of slips 4 are provided with skeleton oil seals 9, and the inner side walls of the two groups of skeleton oil seals 9 are provided with hole retaining rings 19, and the skeleton oil seals 9 are connected to the slips 4 by hexagon bolts 15 and the third spring washer 16, and the upper parts of the two groups of slips 4 are provided with bushings 5, and the two groups of skeleton oil seals 9 are provided with lower seats 8, and the tops of the two groups of lower seats 8 are provided with bearings 10, and the outer walls of the bearings 10 are provided with middle rings 7, The skeleton oil seal 9 is connected to the bottom of the middle ring 7 by the second hexagon socket cylindrical head screw 13 and the second spring washer 14. The top of the bearing 10 is provided with an upper seat 6. The bushing 5 is connected to the upper seat 6 by the first hexagon socket cylindrical head screw 11 and the first spring washer 12. The upper seat 6, the middle ring 7, the lower seat 8 and the bearing 10 form a rotating body. The clamping cylinder 2 pushes the slip seat 3 and the slip 4 to move inward through hydraulic power to clamp the internal drill rod 20 to prevent it from falling. After the clamping cylinder 2 is released, the drill rod 20 is rotated. There is a slight gap between the drill rod 20 and the bushing 5. According to the actual operation, the drill rod 20 disturbs and hits the bushing 5 to generate friction. The bushing 5 will rotate with the drill rod. The upper seat 6, the middle ring 7, the lower seat 8 and the bearing 10 form a rotating body, which rotates at the same time, reduces friction, and protects the outer wall of the drill rod 20 from wear.
