Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to fig. 1-6, the processing device is a clamping block 2 which is used for clamping a ball head 11 of an eyelet bolt 1 and has a columnar structure, the circumferential surface of the clamping block 2 is a clamping surface, an arc-shaped groove 23 which is matched with the ball head 11 for clamping is formed in one side surface of the clamping block 2, the arc-shaped groove 23 can wrap and clamp the ball head 11, the wrapping area of the arc-shaped groove 23 is larger than one half of the surface area of the ball head 11, and the purpose is to prevent the ball head 11 from being separated from the arc-shaped groove 23 due to the fact that the clamping area is too small. The arc-shaped groove 23 has a deformation function and clamps the ball 11 through the deformation function, and a fixing mechanism for fixing the screw 12 of the swing bolt 1 is arranged on one side of the arc-shaped groove 23. During the operation, place bulb 11 in arc 23 earlier, then fix screw rod 12 through fixed establishment, and then fix bulb 11's rotation, be convenient for punch, mill the operation such as bulb 11 surface, it is unset to have solved present bulb 11, rotates easily and leads to the problem that machining error is big when adding man-hour, and simultaneously, this fixed establishment can fix screw rod 12 rotation to arbitrary position, is convenient for carry out the processing operation to bulb 11 surface optional position. The screw 12 with the adjusted processing position is fixed through the fixing mechanism, and then external force is applied to the clamping surface (preferably, the outer peripheral surface of the clamping block 2 is clamped through a chuck), so that the arc-shaped groove 23 is deformed, the surface of the ball head 11 is wrapped and clamped, and the fixing effect on the ball head 11 is further improved.

Further in order to facilitate the effect that the bulb 11 is wrapped and clamped by the arc-shaped groove 23 due to rapid deformation under the condition of applying external force, the clamping block 2 is divided into the first semicircular clamping block 21 and the second semicircular clamping block 22, the arc-shaped groove 23 is divided into the first arc-shaped groove 23a and the second arc-shaped groove 23b, the clamping block 2 and the arc-shaped groove 23 are divided into two halves, and the bulb 11 is convenient to place and clamp. The part of the first semicircular clamping block 21 close to one side of the first arc-shaped groove 23a is divided into opposite quarter clamping blocks 211, clamping grooves 201 are formed between the quarter clamping blocks 211, the same first arc-shaped groove 23a is also divided into quarter arc-shaped grooves, and when the chuck exerts external force on the outer surface of the clamping block 2, the quarter clamping blocks 211 are attached to each other through gaps of the clamping grooves 201, so that the quarter arc-shaped grooves wrap and clamp the ball head 11. The securing mechanism is disposed in the second arcuate slot 23 b. When the swing bolt 1 is fastened by the holder block 2, it is preferable that the screw 12 is located at the side of the second arc-shaped groove 23b, and the screw 12 is rotated to an arbitrary position by the fixing mechanism to be fixed.

Specifically, the fixing mechanism is a linear thread groove 202 which is formed along the second arc-shaped groove 23b toward the edge of the second semicircular clamping block 22 and is matched with the screw 12 for fixing. When the swing bolt 1 is fastened, the screw 12 is rotatably inserted into the linear thread groove 202, the ball head 11 is rotated to a position to be processed, then the nut 3 is sleeved at one end of the screw 12, which is far away from the ball head 11, and is screwed until the screw is contacted with the outer wall surface of the second semicircular clamping block 22, the current processing position of the screw 12 is fastened and limited, then the first semicircular clamping block 21 is connected with the second semicircular clamping block 22, so that the divided first arc-shaped groove 23a is close to the outer surface of the ball head 11, and finally the first semicircular clamping block 21 and the second semicircular clamping block 22 are integrally clamped through a chuck, so that the first semicircular clamping block 21 is tightly attached to the divided quarter-shaped clamping blocks 211 through the gap of the clamping groove 201, and the quarter-shaped groove wraps and clamps the ball head 11 (as shown in fig. 3).

Further, in order to accurately clamp the first arc-shaped groove 23a on the surface of the ball head 11, a groove 21a and a protrusion 22a which are matched with each other are sequentially arranged on the inner side walls of the first semicircular clamping block 21 and the second semicircular clamping block 22, and the protrusion 22a can move in the groove 21 a. In operation, after the screw 12 is fixed in the linear thread groove 202, the groove 21a of the first semicircular clamping block 21 is sleeved on the periphery of the projection 22a of the second semicircular clamping block 22, and when the first semicircular clamping block 21 is clamped by an external force applied through the chuck, the position of the groove 21a on the first semicircular clamping block 21 can move, so that the projection 22a can move in the groove 21a, and the deformation of the first arc-shaped groove 23a in the first semicircular clamping block 21 is not affected.

The principle of the utility model is that: the arc-shaped groove 23 with the deformation function is arranged in the clamping block, and the arc-shaped groove 23 can wrap and clamp the ball head 11 of the swing bolt 1 at any position, so that the machining operation such as drilling or milling and the like can be conveniently carried out at any position of the surface of the ball head 11, the problem that the smooth surface of the ball head 11 is difficult to machine is solved, and the application range of the swing bolt 1 is expanded.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
