The cross plate 32 is correspondingly vertically arranged on the end face of the end plate 31 to form a T-shaped structure. There are two spaced protrusions 33 on the end face of the cross plate 32 away from the end plate 31. Among them, hole punching processing needs to be carried out on the end face of the end plate 31 away from the cross plate 32 and on the cross plate 32.

[0029] As Figure 2 shown, the present application proposes a T-shaped block processing fixture, which includes a frame 1. A rotatable mounting plate 2 is arranged on the frame 1. A plurality of processing stations are arranged on both sides of the mounting plate 2 along the width direction for clamping the T-shaped block 3. Placing the processing fixture clamping a plurality of T-shaped blocks 3 as a whole in a drilling machine tool can simultaneously perform hole punching processing on a plurality of T-shaped blocks 3, effectively improving work efficiency.

[0030] As Figure 2 shown, the frame 1 includes a base plate 11. Two upright support plates 12 are arranged on the base plate 11. Turntables 13 are arranged on the opposite side end faces of the support plates 12. The two ends of the mounting plate 2 along the length direction are correspondingly arranged on the turntables 13. Placing the frame 1 on a drilling machine tool and using the rotating assembly of the machine tool to drive the turntable 13 to rotate to realize the synchronous rotation of the mounting plate 2, so as to perform hole punching on other end faces of the T-shaped block 3 clamped on the mounting plate 2.

[0031] As Figures 1-4As shown in the figure, the processing station includes a notch 21 formed in the placement plate 2, and the T-shaped block 3 is correspondingly placed in the notch 21. A horizontally protruding step 22 is provided in the notch 21 for supporting the horizontal plate 32 of the T-shaped block 3. A pressing member 25 is cooperatively provided above the step 22. When the horizontal plate 32 is placed on the step 22, the pressing member 25 can be pressed above the horizontal plate 32 to fix the T-shaped block 3 and prevent the T-shaped block 3 from having displacement in the vertical direction. The pressing member 25 includes a lifting cylinder 251 provided on the upper end surface of the placement plate 2. The output end of the lifting cylinder 251 faces upward, and the end of the push rod is rotatably connected to a transmission plate 253 through a first rotating shaft 252. One end of the transmission plate 253 away from the lifting cylinder 251 is provided with a downwardly extending lower pressing plate 254 for pressing the horizontal plate 32. One side of the lifting cylinder 251 close to the corresponding notch 21 is rotatably connected to a connecting rod 255 through a second rotating shaft 256. One end of the connecting rod 255 away from the second rotating shaft 256 is rotatably connected to the middle of the transmission plate 253 through a third rotating shaft 257.

[0032] As Figures 1-4 shown in the figure, when the lifting cylinder 251 operates and the push rod extends out, the end of the transmission plate 253 connected to the push rod moves upward. The transmission plate 253 rotates around the third rotating shaft 257, and the end of the transmission plate 253 provided with the lower pressing plate 254 moves downward correspondingly, and the lower pressing plate 254 presses the horizontal plate 32. Preferably, three groups of convex blocks 33 on the horizontal plate 32 and the lower pressing plate 254 are correspondingly arranged at intervals, and the lower end surface of the lower pressing plate 254 is correspondingly provided with a toothed structure to increase the friction between the lower pressing plate 254 and the horizontal plate 32 and ensure that the horizontal plate 32 can be pressed tightly between the lower pressing plate 254 and the step 22.

[0033] As Figures 1-5 shown in the figure, clamping matching blocks 23 and clamping members 24 for clamping both sides of the end plate 31 of the T-shaped block are further provided in the notch 21. The clamping member 24 includes a movable clamping block 242 and a clamping cylinder 241 for driving the movable clamping block 242 to approach and move away from the clamping matching block 23. Among them, the clamping matching block 23 and the movable clamping block 242 are oppositely arranged along the length direction of the placement plate 2. The clamping matching block 23 is correspondingly fixed on the inner wall of the notch to provide a reference clamping surface. The movable clamping block 242 approaches the clamping matching block 23 to complete the clamping action to limit the horizontal movement of the T-shaped block 3.

[0034] As Figures 1-5As shown, preferably, a receiving groove 27 is formed on one side of the slot 21 along the length direction of the mounting plate 2, and the clamping cylinder 241 is correspondingly placed in the receiving groove 27. There is a separating portion 28 between the slot 21 and the receiving groove 27, and a guiding hole (not shown) is formed on the separating portion 28. The guiding hole communicates with the slot 21 and the receiving groove 27 on both sides, and the movable clamping block 242 is correspondingly placed in the guiding hole. The movable clamping block 242 reciprocates along the guiding hole under the drive of the clamping cylinder 241, effectively improving the stability of the movable clamping block 242 during the moving process.

[0035] As Figures 1-5 shown, preferably, there is a gap between the inner wall of the guiding hole and the movable clamping block 242, and the gap range is 0.03 - 0.05 mm to ensure that the movable clamping block 242 can slide smoothly in the guiding hole.

[0036] As Figures 1-5 shown, preferably, the receiving groove 27 can be correspondingly arranged between the two slots 21. The clamping cylinder 241 in the receiving groove 27 has two output ends arranged in opposite directions, and movable clamping blocks 242 are correspondingly connected to the output ends. A single clamping cylinder 241 can simultaneously implement the clamping actions of the T-shaped blocks 3 in two sets of processing stations, effectively saving the usage space on the mounting plate 2 and reducing costs.

[0037] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
