When the PCB needs to be turned over. At this time, the PCB fixture 1 needs to be turned over, the second locking bolt 21 located at the upper end of the mounting box 2 is loosened to make the second locking bolt 21 away from the shaft body of the rotating shaft 12, and the screw rod 31 does not rotate, so that the locking structure 5 releases the locking of the rotating shaft 12. And then the rotating shaft 12 is rotated by the rotating hand wheel I11, so that the right clamp 1 is turned over, and the left clamp 1 is driven to turn over. The second lock bolt 21 is tightened to fix the jig 1. Therefore, the operation of turning the PCB is realized, and the back of the PCB is processed.

Example two

Based on the locking structure 5 that embodiment one provided, the utility model discloses still provide the further scheme who suits locking structure 5 and lead screw 31.

Referring to fig. 1 and 5-9, the present invention provides an adjustable clamp for PCB processing.

The rod body of the screw rod 31 is connected with a first gear 312 for meshing a second gear 52 through a key, and the right side of the second gear 52 is arranged right below the box cavity of the box 2. The right end welding of lead screw 31 has been used for carrying out pivoted hand wheel two 311 to lead screw 31, has seted up the screw thread on the body of rod of the left side of lead screw 31, and the spiro union has been used for making the slider 33 that moves about the mounting bracket 2 that is located the left side on the screw thread section body of rod, and the welding of the upper end of slider 33 has left install bin 2.

The locking structure 5 comprises a support rod 51 welded on the left and right side walls of the box cavity of the right mounting box 2, a second gear 52 engaged with the first gear 312 is connected to the rod body of the support rod 51 through a key, and the second gear 52 rotates around the axis of the support rod 51. The rack 53 used for being meshed with the second gear 52 is installed on the front side and the rear side of the second gear 52, a square hole is formed in the middle of the plate body of the rack 53, a connecting rod 531 used for supporting the rack 53 is inserted in the square hole, and the connecting rod 531 is a square rod. The lower end of the connecting rod 531 is sleeved with a spring 532, and the spring 532 is used for resetting the rack 53. An L-shaped rod 533 is bonded to one end, away from the teeth, of the rack 53, a locking ring 54 for locking the rotating shaft 12 is mounted above the rack 53, a U-shaped rod 55 for limiting the locking ring 54 is welded to a ring body of the locking ring 54, and the U-shaped rod 55 is U-shaped. U-shaped rod 55 is inserted into the box cavity from the round hole in the upper end of right mounting box 2, and the U-shaped rod is in sliding fit with mounting box 2.

When a user processes the PCB, one end of the PCB is fastened and fixed by the right clamp 1. And tightening the first locking bolt 16 on the right clamp 1, so that the adjusting plate 15 moves downwards to clamp the PCB plate when the first locking bolt 16 is tightened.

The second hand wheel 311 is rotated to rotate the screw rod 31. The sliding block 33 which is matched with the rod body in the left threaded section of the screw rod 31 in a threaded manner is driven to move left and right, and meanwhile, the left installation box 2 welded on the sliding block 33 moves along with the sliding block. When the hand wheel 311 rotates forward, the first gear 312 on the rod body of the screw rod 31 rotates forward at the same time. Therefore, the second gear 52 meshed with the first gear 312 rotates positively and drives the front rack 53 meshed with the second gear 52 to move downwards, the rear rack 53 meshed with the second gear 52 is driven to move upwards, and an L-shaped plate is bonded to the rear rack 53 away from the teeth, so that when the rear rack 53 moves upwards, the L-shaped plate 533 is driven to move upwards, the L-shaped plate 533 acts on the ring body of the locking ring 54, and the locking ring 54 moves upwards to lock the shaft body of the rotating shaft 12 in the right clamp 1. Under the action of the support rod 531 inserted into the square hole of the rear rack 53 and the spring 532 on the rod body of the rear support rod 531, the L-shaped plate 533 continuously acts on the locking ring 54 when the screw rod 31 rotates forward, so that the rotating shaft 12 cannot rotate all the time when the screw rod 31 rotates forward. The purpose is that when a user drives the left installation box 2 on the sliding block 33 to adjust the distance through the first rotating hand wheel 311, the clamp 1 is prevented from being overturned when the left installation box 2 moves left and right. When the distance adjustment of the left installation box 2 is completed and the PCB needs to be turned over, the right clamp 1 can be rotated by rotating the second hand wheel 11. Therefore, when the left installation box 2 is adjusted left and right, the right clamp 1 can not be turned all the time, and when the left installation box 2 does not move, the right clamp 1 can be turned over by rotating the second hand wheel 12. According to the length of the PCB, the hand wheel 311 is rotated to drive the right installation box 2 to move left and right, so that the left clamp 1 is adjusted to clamp and fix the other end of the PCB.

When another panel of the PCB needs to be processed. At this time, the PCB fixture 1 needs to be turned over, and the first locking bolt 21 is loosened by screwing upwards, so that the first locking bolt 21 is far away from the shaft body of the rotating shaft 12. At this time, the screw 31 is not rotated, and the locking ring 54 is unlocked from the shaft body of the rotary shaft 12. And rotating the first hand wheel 11 to turn the right clamp 1, so that the left clamp 1 is carried and turned over simultaneously. The first lock bolt 21 is tightened to fix the jig 1, and the back surface of the PCB board is processed.

Based on the above disclosure and the accompanying drawings, those skilled in the art can understand and implement the present invention. In addition, any non-inventive modification of the present invention by those skilled in the art without creative work still belongs to the protection scope of the present invention.
