The inner end surfaces of the second connecting holes 301 are provided with threads. The two ends of the placing plate 3 are clamped in the clamping grooves 201 on the inner end surface of the fixed side plate 2.

[0036] The fixed shaft 4 is symmetrically provided with two groups, and the outer end surface of the front end portion of the fixed shaft 4 is provided with a thread;

[0037] Electric cylinder 5, two groups of electric cylinder 5 are symmetrically arranged, the electric cylinder 5 is fixed to the upper end surface of the base plate 1, and a telescopic rod 501 is installed on the upper end of the electric cylinder 5;

[0038] A clamping block 6 is fixedly mounted on the upper end surface of the placement plate 3, and a clamping groove is provided on the surface of the clamping block 6;

[0039] The workpiece 7 has a U-shaped front end and a rectangular plate-shaped rear end. A first processing hole 701 is formed on the rear end surface of the workpiece 7.

[0040] Among them, a first connecting hole 202 is opened on the surface of the fixed side plate 2, the front end of the fixed shaft 4 passes through the first connecting hole 202 and is threadedly connected to the second connecting hole 301 on the surface of the placing plate 3, the lower end surface of the slot 201 is a horizontal structure, and the upper end surface of the slot 201 is an inclined structure. During use, the front end of the fixed shaft 4 passes through the first connecting hole 202 and is threadedly connected to the second connecting hole 301 on the surface of the placing plate 3, so that the placing plate 3 can rotate around the fixed shaft 4.

[0041] Among them, two guide plates 302 are fixedly installed on the rear end surface of the placement plate 3, and a long through hole 3021 is opened on the surface of the guide plate 302. The outer end surface of the upper end part of the telescopic rod 501 is opened with a thread. The upper end part of the telescopic rod 501 is clamped in the through hole 3021 on the surface of the guide plate 302. Two nuts are provided on the surface of the telescopic rod 501. The inner end surfaces of the two nuts are respectively fitted with the upper and lower end surfaces of the guide plate 302. The upper end of the telescopic rod 501 is clamped in the through hole 3021. After the electric cylinder 5 is started, the telescopic rod 501 can be moved upward or downward, so that the inclination angle of the placement plate 3 can be adjusted.

A second processing hole 702 is opened on the surface of the front end part of the workpiece 7, and the central axis of the second processing hole 702 is perpendicular to the surface of the workpiece 7. During use, when the telescopic rod 501 of the electric cylinder 5 drives the front end of the placement plate 3 to move upward, the inclination angle of the front end part of the workpiece 7 is set to be the same as the inclination angle of the upper end part of the slot 201, so that the front end part of the workpiece 7 is in a horizontal state at this time, which is convenient for drilling the second processing hole 702.

[0043] The specific usage and function of this embodiment are as follows:

[0044] In the utility model, the worker clamps the workpiece 7 in the clamping groove on the surface of the clamping block 6. At this time, the lower end surface of the placing plate 3 is in contact with the bottom end surface of the clamping groove 201, and the placing plate 3 is in a horizontal state. Then the drill bit can perform drilling operation on the rear end of the workpiece 7. At this time, the first processing hole 701 on the surface of the workpiece 7 is formed. When operating on the second processing hole 702 on the front end surface of the workpiece 7, the electric cylinder 5 can be started. The telescopic rod 501 at the front end of the electric cylinder 5 is clamped in the through hole 3021 on the surface of the guide plate 302, and two nuts are provided on the surface of the telescopic rod 501, so that when the telescopic rod 501 at the front end of the electric cylinder 5 moves upward, it can drive the guide plate 302 to move upward. The guide plate 302 is fixedly connected to the placing plate 3, and is also connected to the second processing hole 202 on the surface of the placing plate 3 through the front end of the fixed shaft 4. The arrangement in the second connecting hole 301 allows the placement plate 3 to rotate around the fixed axis 4. When the upper end surface of the placement plate 3 is in contact with the top end surface of the slot 201, the telescopic rod 501 at the front end of the electric cylinder 5 stops moving upward. Since the inclination angle of the front end portion of the workpiece 7 is the same as the inclination angle of the upper end portion of the slot 201, when the placement plate 3 is in contact with the top end surface of the slot 201, the front end portion of the workpiece 7 is in a horizontal state. At this time, the drill bit can drill the front end portion of the workpiece 7, so that the second processing hole 702 on the front end surface of the workpiece 7 can be formed. At this time, the center axis of the second processing hole 702 is perpendicular to the surface of the workpiece 7, which meets the processing standards. A set of fixtures can drill and form the first processing hole 701 and the second processing hole 702, thereby improving work efficiency.

[0045] Embodiment 2: Based on the electric cylinder 5 in Embodiment 1, in actual application, an air cylinder can be used to replace the electric cylinder 5. After the air cylinder is started, it can drive the guide plate 302 to move upward, so as to adjust the inclination angle of the placement plate 3 and make the front end part of the workpiece 7 in a horizontal state, which is convenient for workers to operate the second processing hole 702.
