Referring to fig. 3, 4 and 7, two longitudinal clamping assemblies 5 are symmetrically arranged on both sides of the fixing plate 41.

The longitudinal clamping assembly 5 comprises an L-shaped cylinder seat 51 fixed on the workbench 3 on two sides of the fixed plate 41 through bolts, a first cylinder 52 horizontally fixed on the cylinder seat 51 through bolts and vertically fixed on the plate 41, and a first pressing claw 53 connected on a guide rod of the first cylinder 52 and used for clamping the inner side end face of the vertical plate 12 of the support plate 1.

Referring to fig. 8, the tail of the first pressing claw 53 is U-shaped and is horizontally and rotatably connected to the guide rod of the first cylinder 52 through a pin, a connecting block 54 is fixed to the front end surface of the first cylinder 52 opposite to the first pressing claw 53 by a bolt, the connecting block 54 is an integrally formed T-shaped structure, the longitudinal structure of the connecting block 54 is fixedly connected to the front end surface of the first cylinder 52 through a bolt, the upper and lower end surfaces of the transverse structure of the connecting block 54 are respectively connected to one end of a connecting plate 55 through a pin, and the other end of the connecting plate 55 is rotatably connected to the first pressing claw 53 through a pin vertically penetrating through the first pressing claw 53.

Through the structure of the longitudinal clamping assembly 5, when the support plate 1 is sleeved on the positioning column 15, the guide rod of the first air cylinder 52 extends out to drive the first pressing claw 53 to rotate clockwise so as to press the inner side end face of the vertical plate 12 of the support plate 1, and when the guide rod of the first air cylinder 52 retracts, the first pressing claw 53 is driven to rotate anticlockwise so as to loosen the inner side end face of the vertical plate 12, so that the support plate 1 can be taken away conveniently. Because the first pressing claw 53 is located below the connecting column 15 when being clamped, in order to avoid that the first pressing claw 53 does not block the drill when drilling a through hole in the connecting column 15, as shown in fig. 8, the upper and lower end surfaces of the head of the first pressing claw 53 are provided with notches 56. In this embodiment, the first cylinder 52 may be a constant-lift HITOP cylinder.

Referring to fig. 3, 4, 7 and 9, the rotary clamping assemblies 6 are arranged outside the fixed plate 41, the rotary clamping assemblies 6 are arranged on the upper end surface of the workbench 3 between the two first air cylinders 52, and two groups of rotary clamping assemblies 6 are arranged to improve clamping stability.

The rotating clamping assembly 6 comprises a rotating clamping cylinder 61 and a second pressing claw 62, the rotating clamping cylinder 61 is perpendicular to the direction of the fixed plate 41 and fixed on the end face of the outer side of the fixed plate 41 through a bolt, a sliding through hole 44 is formed in the fixed plate 41 along the direction of the positioning column 42, a guide rod of the rotating clamping cylinder 61 penetrates through the sliding through hole 44 in a sliding mode, the top of the guide rod of the rotating clamping cylinder 61 extends out of the fixed plate 41, the second pressing claw 62 is perpendicularly fixed on the guide rod of the rotating clamping cylinder 61 on the inner side of the fixed plate 41 through a bolt, and the second pressing claw 62 is used for clamping the end face of the inner side of the vertical plate 12 of the supporting plate 1.

Because when the supporting plate 1 is installed on the processing jig, the installation through hole 14 needs to be sleeved on the positioning column 42, if a common non-rotating clamping cylinder is adopted, in order to sleeve the installation through hole 14 on the positioning column 42, the vertical plate 12 is not blocked by the second pressing claw 62, the stroke of the cylinder needs to be large, and thus the clamping stability is easily caused to be low. The utility model discloses an adopt rotatory centre gripping cylinder 61, when establishing the reference column 42 with installation through-hole 14 cover, because second pressure claw 62 is the horizontal direction, can not cause stopping vertical board 12, through adopting rotatory centre gripping cylinder, the high and compact structure of centre gripping stability. In the present embodiment, the rotary clamping cylinder 61 may be a CHElIC air vertical rotary clamping cylinder.

Through the structure of the rotating and clamping assembly 6, when the supporting plate 1 is sleeved on the positioning column 15, the rotating and clamping cylinder 41 firstly drives the second pressing claw 42 to rotate to the upper side, and then the guide rod of the rotating and clamping cylinder 41 retracts to drive the second pressing claw 42 to press the end face of the inner side of the vertical plate 12; when the support plate 1 needs to be taken away, the guide rod of the rotary clamping cylinder 41 stretches to drive the second pressing claw 42 to be away from the vertical plate 12, and then the guide rod of the rotary clamping cylinder 41 rotates to drive the second pressing claw 42 to rotate. Therefore, the supporting plate 1 can be conveniently clamped, fixed, loosened and taken out by rotating the clamping cylinder 41 and the second pressing claw 42. In order to improve the clamping stability, two groups of rotary clamping cylinders 61 and first press claws 62 matched with the rotary clamping cylinders are arranged in parallel.

Through the above, location and centre gripping fixed to vertical board 12 can be realized to reference column 42, vertical centre gripping subassembly 5 and rotatory centre gripping subassembly 6, because when milling the horizontal plate 11 of backup pad 1 and spliced pole 15 carries out the drilling operation, the horizontal plate 11 of keeping away from the fixed plate 41 direction can produce great moment of torsion owing to be in unsettled state to lead to first pressure claw 53 and second pressure claw 62 atress too big. For this purpose, the support member 7 is disposed under the horizontal plate 11 in a suspended state in a direction away from the fixed plate 41.

Referring to fig. 3, 4 and 6, the supporting assembly 7 includes two vertical posts 71 vertically connected to the upper end surface of the working table 3 by bolts, the vertical posts 71 are disposed opposite to the inner sides of the fixing plates 41, and the vertical posts 71 are used for supporting the horizontal plate 11 of the supporting plate 1.
