[0025] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0026] The present utility model provides asFigures 1-5 A machining fixture that is convenient for adjusting the angle, including a base 1, which supports the machining fixture;

[0027] A placement rack 3 is arranged above the base 1. An adjusting mechanism 2 is installed between the base 1 and the placement rack 3 for adjusting the inclination angle of the placement rack 3. The adjusting mechanism 2 includes a fixed frame 201, a driving motor 202, a first turntable 203, a transmission belt 204, a second turntable 205, a first lead screw 206, a movable frame 207, and a movable rod 208. The fixed frame 201 is fixed on both sides above the base 1. A driving motor 202 is fixedly arranged on one side of the fixed frame 201. The output end of the driving motor 202 is fixedly installed with a first turntable 203. One end of the first turntable 203 is fixedly installed with a first lead screw 206. The outer part of the first lead screw 206 is movably connected with a movable frame 207. The placement rack 3 is installed on one side of the movable frame 207. Movable rods 208 are movably connected between both sides of the placement rack 3 and the base 1. Screws 4 are arranged on both inner sides of the placement rack 3. One end of the screw 4 is fixedly installed with a turning handle 5. The outer part of the screw 4 is movably connected with a moving frame 6;

[0028] A clamping mechanism 8 is arranged on one side of the moving frame 6 for clamping the workpiece. By turning on the switch of the driving motor 202, the first turntable 203 is driven to rotate. The transmission belt 204 and the second turntable 205 outside are driven to rotate by the rotation of the first turntable 203, so that the two groups of first lead screws 206 rotate, driving the outer movable frame 207 and the placement rack 3 to move. The movable rods 208 on both sides of the placement rack 3 and the base 1 form a supporting rotation, so that the placement rack 3 can be adjusted at an inclined angle, improving the practicability of processing.

[0029] As Figure 2 shown, a transmission belt 204 is sleeved outside the first turntable 203. The other side of the transmission belt 204 is movably connected with a second turntable 205. When the driving motor 202 drives the first turntable 203, the transmission belt 204 outside the first turntable 203 drives the second turntable 205 to rotate, so that the two groups of first lead screws 206 can rotate simultaneously, facilitating the angle adjustment of the placement rack 3.

[0030] As Figure 1 、 Figure 3 and Figure 4 shown, a servo motor 7 is arranged on one side of the moving frame 6. The clamping mechanism 8 is fixedly installed at the output end of the servo motor 7. By turning on the switch of the servo motor 7, the whole clamping mechanism 8 and the workpiece can be driven to perform flipping adjustment, facilitating the staff to adjust the positions of different processes.

[0031] As Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, the clamping mechanism 8 includes a connecting frame 801, a limiting groove 802, a handle 803, a second lead screw 804, a clamping block 805, a limiting block 806, and a rubber pad 807. The connecting frame 801 is installed on one side of the moving frame 6. A handle 803 is provided on one side of the connecting frame 801. One end of the handle 803 is fixedly installed with a second lead screw 804. The second lead screw 804 is provided in two groups, and the threading directions of the two groups of second lead screws 804 are opposite. The outside of the second lead screw 804 is movably connected with a clamping block 805. A rubber pad 807 is pasted on one side of the clamping block 805. By placing the workpiece in the clamping block 805 and rotating the handle 803 to drive the second lead screw 804 to rotate, the clamping block 805 and the rubber pad 807 clamp the workpiece in the middle, improving the stability of the workpiece during processing.

[0032] As Figure 5 shown, a limiting groove 802 is opened on one side surface of the connecting frame 801. A limiting block 806 is fixedly installed on one side of the clamping block 805. The limiting groove 802 and the limiting block 806 are used in cooperation. When the second lead screw 804 rotates to drive the clamping block 805, the limiting block 806 behind the clamping block 805 slides in a limited manner in the limiting groove 802 inside the connecting frame 801, improving the stability during movement.

[0033] The working principle of this utility model: First, connect to the external power supply. Then place the workpiece between the clamping blocks 805 on both sides above the placing frame 3. Then, according to the length of the workpiece, rotate the turning handles 5 on both sides of the placing frame 3 to drive the screw rod 4 to rotate, so that the moving frame 6 outside the screw rod 4 slides with the clamping mechanism 8. When the appropriate length for the workpiece is adjusted, then rotate the handle 803 to drive the second lead screw 804 to rotate. By using the opposite threading directions of the two groups of second lead screws 804, drive the two groups of clamping blocks 805 and the rubber pads 807 outside to clamp the workpiece in the middle. After the clamping and limiting are completed, according to the processing angle, turn on the switch of the driving motor 202 to drive the first turntable 203 to rotate. Use the rotation of the first turntable 203 to drive the external transmission belt 204 and the second turntable 205 to rotate, so as to drive the two groups of first lead screws 206 to rotate simultaneously, making the movable frames 207 outside the two groups of first lead screws 206 move with the placing frame 3. And during the movement of the placing frame 3, it forms a supporting rotation with the base 1 through the movable rods 208 on both sides, so that the placing frame 3 can be adjusted at an inclined angle, improving the practicality of processing. When the angle is adjusted, turn off the switch of the driving motor 202. Next, when the other side of the workpiece needs to be processed during the processing, turn on the switch of the servo motor 7 on one side of the moving frame 6 to drive the entire clamping mechanism 8 and the workpiece to flip. After flipping to the surface to be processed, turn off the switch of the servo motor 7. Finally, when the workpiece processing is completed, remove the workpiece through the above steps, and then cut off the external power supply. Just like this, the use process of this machining fixture that is convenient for adjusting the angle is completed.

[0034] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model.
