Example (b):

as shown in fig. 1-7, the utility model provides a spring clamp plate inclined hole bores counterboring anchor clamps, including base 1, roating seat 2, driving piece 3 and clamping piece 4. Base 1 both sides all are provided with stand 9, and the pivot swivelling joint of roating seat 2 is in the top of stand 9, and then articulates in base 1. Specifically, the two ends of the rotating base 2 are provided with rotating shafts in an interference fit manner. The outside of the rotating shaft is installed with the upright post 9 through a quenching sleeve. The quenching sleeve is in interference fit with the upright post 9, and the rotating shaft and the quenching sleeve are in micro clearance fit, so that the rotating seat 2 can rotate around the axis. The driving member 3 is disposed on the base 1. The driving member 3 is used for driving the rotary base 2 to rotate relative to the base 1. The driving member 3 may be a motor. In this embodiment, the driving member 3 is a hydraulic cylinder. The hydraulic cylinder is connected to the base 1 and is located below the rotating base 2. The bottom of the rotary seat 2 is provided with a rotary plate 8. The telescopic rod of the hydraulic cylinder is hinged with the rotating plate 8. The hydraulic cylinder can stretch out and draw back to drive the rotating plate 8 and the rotating base 2 to rotate, and then the angle of the spring pressing plate 5 is adjusted. The clamping member 4 is attached to the rotary base 2 by means of screws. The clamping element 4 is arranged in a manner such that it engages with the spring plate 5. When the spring pressure plate 5 is placed on the rotary base 2, the clamping member 4 extends partially above the spring pressure plate 5, so that the clamping member 4 can clamp the spring pressure plate 5 to the rotary base 2.

One side of the spring pressing plate 5 is concave, and the other side is convex. The utility model discloses a spring clamp plate inclined hole bores counter boring anchor clamps and when using, places spring clamp plate 5 sunken one side in roating seat 2. Meanwhile, the spring pressing plate 5 is clamped on the rotating base 2 through the clamping piece 4, and then the spring pressing plate 5 and the rotating base 2 are fixed. Subsequently, control driving piece 3 for driving piece 3 drive roating seat 2 is rotatory, and the both ends bottom surface of roating seat 2 carries out automatic spacing at the spacing step of stand 9, makes rotation angle just accord with the predetermined requirement, and then makes the processing position of spring clamp plate 5 uplift one side just to processing equipment. After the drilling and the spot facing in the hole on one side of the spring pressing plate 5 are finished, the driving piece 3 rotates again and is automatically positioned, and then the other side of the spring pressing plate 5 rotates to be opposite to the machining equipment.

Through the utility model discloses a spring clamp plate inclined hole bores counter boring grab can quick clamping spring clamp plate 5. Simultaneously, adjustment and automatic positioning spring clamp plate 5's angle that can be quick, and then conveniently drill and downthehole spherical facing of reaming to spring clamp plate 5 both sides.

In this embodiment, the shape of the rotary base 2 is matched with the concave surface of the spring pressing plate 5, so that when the spring pressing plate 5 is placed above the rotary base 2, the concave surface of the spring pressing plate 5 is attached to the outer surface of the rotary base 2. This just makes spring clamp 5 better with roating seat 2 cooperation, and then guarantees that spring clamp 5 adds man-hour more stable and can not rock.

In the present embodiment, 3 clamping members 4 are provided. The 3 clamping pieces 4 are distributed along the axial direction of the rotating base 2, so that a placing position for placing the spring pressing plate 5 is formed between the two adjacent clamping pieces 4. This enables the rotary base 2 to hold two spring clamps 5 at a time, thereby enabling two spring clamps 5 to be machined at a time. The processing efficiency is improved.

In this embodiment, the rotating base 2 is provided with the positioning pins 6 on both sides of each placing position. The locating pin 6 can be quick fix a position spring clamp plate 5, improves spring clamp plate 5 dress and presss from both sides in the efficiency of roating seat 2.

In the present embodiment, a compression spring 7 is provided between the clamp 4 and the rotary base 2. After the screw is loosened, the clamping piece 4 is gradually separated from the surface of the spring pressing plate 5 under the action of the compression spring 7, then the clamping piece 4 is manually rotated by 90 degrees, the spring pressing plate 5 is completely exposed, and the spring pressing plate 5 can be conveniently taken down. Meanwhile, the gap between the clamping piece 4 and the rotating seat 2 facilitates the spring pressing plate 5 to enter the gap between the clamping piece 4 and the rotating seat 2, and then the clamping piece 4 is rotated back by 90 degrees and placed above the spring pressing plate, so that rapid clamping is realized.

In this embodiment, two ends of the rotating plate 8 are respectively hinged with a hydraulic cylinder. Both sides of the base 1 are provided with upright posts 9. The rotating shaft of the rotating base 2 is rotatably connected to the top end of the upright post 9. The inner side of the upright post 9 is provided with a limit step 91 in cooperation with the rotating seat 2. When the rotary base 2 swings to a horizontal state, a gap is left between the rotary base 2 and the limiting step 91. When the left side of the rotating seat 2 rotates to the left limit at the rotating seat 2, the limiting step is abutted. Thereby preventing the rotary base 2 from continuing to rotate leftwards. The right side of swivel mount 2 abuts limit step 91 when swivel mount 2 rotates to the right limit. Thereby preventing the rotary base 2 from continuing to rotate to the right. Therefore, when the rotating seat 2 rotates to a required angle, the rotation is automatically stopped, and the aim of accurate rotation angle is achieved. The roating seat 2 is rotated in two pneumatic cylinder cooperations, including the combined action of spacing step for 2 both sides of roating seat can both be fine firm support, can not rock in the 5 course of working of spring clamp. The hinge points of the rotating plate 8 are all provided with kidney-shaped holes. The telescopic rod of the hydraulic cylinder is hinged with the waist-shaped hole. So that the rotation plate 8 can be normally rotated.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
