Description

Technical Field

[0001] The utility model belongs to the technical field of photo frame processing, and particularly relates to an automatic clamping device of a photo frame corner cutting machine. Background Art

[0002] Photo frames are widely used. The manufacturing parts of ordinary photo frames are all horizontal cuts, which are then connected to make photo frames. This photo frame structure connection is not stable enough. We need a bevel cut photo frame structure, which is more stable and more beautiful. Therefore, we need a device for cutting the bevel of the photo frame.

[0003] The prior art photo frame angle cutting machine is usually provided with a 90° arranged backrest, and a spacing is set at the center of the angle between the two backrests. A rectangular through hole is provided on the photo frame angle cutting machine at a position corresponding to the spacing, and a circular saw blade driven by a motor is provided in the rectangular through hole. During operation, the operator manually places the photo frame wood against the backrest, starts the circular saw blade to cut the photo frame wood, and completes the 45° angle cutting of the photo frame wood. However, the angle between the two backrests in the prior art is fixed, resulting in that only the photo frame corner with a fixed angle can be cut, and the applicability is poor. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic clamping device for a photo frame corner cutting machine to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: an automatic clamping device for a photo frame beveling machine, comprising a base plate, a backing grid, an adjustment assembly, and a clamping assembly, wherein the backing grid is hinged to the base plate, and there are two backing grids, which are symmetrically distributed. The adjustment assembly is provided on one side of the backing grid, and the clamping assembly is provided on the other side of the backing grid;

[0006] The adjustment assembly includes a motor, a screw, a slider and a connecting rod. The motor is fixedly mounted on the base plate, the screw is fixedly mounted on the motor output shaft, the slider is sleeved on the screw and threadedly connected to the screw, and the connecting rod is hinged between the slider and the fence.

[0007] As a preferred embodiment, a cutting groove is provided on the top of the bottom plate on the symmetrical center line of the two fences.

[0008] As a preferred embodiment, shaft seats are rotatably mounted on both ends of the screw, and the shaft seats are fixedly mounted on the base plate.

[0009] As a preferred embodiment, a sliding groove parallel to the screw is provided on the top surface of the bottom plate, and the slider slides in the sliding groove.

[0010] As a preferred embodiment, the clamping assembly includes a support plate, a cylinder and a clamping rod, the support plate is fixedly connected to the side close to the grid, the cylinder is fixedly installed on the support plate, and the clamping rod is fixedly connected to the piston end of the cylinder.

[0011] As a preferred embodiment, the cylinder is arranged perpendicular to the fence, and the clamping rod is arranged parallel to the fence.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The automatic clamping device of the photo frame angle cutting machine is provided with an adjustment component. When cutting photo frame corners of different angles, the motor can be started to drive the screw to rotate, so that the screw drives the slider to slide along the slide groove, and the slider drives the support grid to rotate through the connecting rod, so that the angle between the two support grids can be adjusted. When the photo frame wood is against the support grid, the photo frame wood and the circular saw blade form different angles, so that photo frame corners of different angles can be cut, thereby improving applicability.

[0014] The automatic clamping device of the photo frame corner cutting machine is provided with a clamping assembly. When cutting corners, the cylinder can be activated to drive the clamping rod to move, so that the clamping rod pushes the photo frame wood against the fence, and the photo frame wood is automatically clamped, which can reduce manual work and reduce danger.

[0021] See also Figure 1-3The utility model provides an automatic clamping device for a photo frame angle cutting machine, comprising a base plate 1, a backrest 2, an adjustment component 3 and a clamping component 4. The backrest 2 is hinged on the base plate 1. There are two backrests 2, which are symmetrically distributed. The backrest 2 is used to position the photo frame wood. A cutting groove 11 is provided on the top of the base plate 1 on the symmetrical center line of the two backrests 2. The cutting groove 11 is used to pass a circular saw blade. The adjustment component 3 is arranged on one side of the backrest 2. The adjustment component 3 includes a motor 31, a screw 32, a slider 33 and a connecting rod 34. The motor 31 is fixedly mounted on the base plate 1, and the screw 32 is fixedly mounted on the output shaft of the motor 31. The screw 32 is arranged horizontally, and both ends of the screw 32 are rotatably mounted with shaft seats 35. The cam 33 is fixedly mounted on the base plate 1, the slider 33 is sleeved on the screw rod 32 and is threadedly connected to the screw rod 32, and the connecting rod 34 is hinged between the slider 33 and the fence 2; the top surface of the base plate 1 is provided with a slide groove 12 parallel to the screw rod 32, and the slider 33 slides in the slide groove 12. By setting the adjustment component 3, when cutting the frame corners of different angles, the motor 31 can be started to drive the screw rod 32 to rotate, so that the screw 32 drives the slider 33 to slide along the slide groove 12, so that the slider 33 drives the fence 2 to rotate through the connecting rod 34, thereby adjusting the angle between the two fences 2. When the frame wood is against the fence 2, the frame wood and the circular saw blade form different angles, so that the frame corners of different angles can be cut, thereby improving applicability.

[0022] Reference Figure 3 The clamping assembly 4 is provided on the other side of the fence 2. The clamping assembly 4 includes a support plate 41, a cylinder 42 and a clamping rod 43. The support plate 41 is fixedly connected to one side of the fence 2. The cylinder 42 is fixedly installed on the support plate 41. The cylinder 42 is arranged perpendicular to the fence 2. The clamping rod 43 is fixedly connected to the piston end of the cylinder 42. The clamping rod 43 is arranged parallel to the fence 2. By setting the clamping assembly 4, when cutting the angle, the cylinder 42 can be started to drive the clamping rod 43 to move, so that the clamping rod 43 pushes the photo frame wood against the fence 2, and the photo frame wood is automatically clamped, which can reduce manual work and reduce danger.

[0023] The working principle and usage process of the present invention are as follows: First, by setting the adjustment component 3, when cutting the corners of the photo frame at different angles, the motor 31 can be started to drive the screw 32 to rotate, so that the screw 32 drives the slider 33 to slide along the slide groove 12, and the slider 33 drives the fence 2 to rotate through the connecting rod 34, so that the angle between the two fences 2 can be adjusted. When the photo frame wood rests on the fence 2, the photo frame wood and the circular saw blade form different angles, so that photo frame corners at different angles can be cut, thereby improving applicability. By setting the clamping component 4, when cutting the angle, the cylinder 42 can be started to drive the clamping rod 43 to move, so that the clamping rod 43 pushes the photo frame wood to rest on the fence 2, and the photo frame wood is automatically clamped, which can reduce manual work and reduce danger.
