DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 2As shown in Figure 4, in this embodiment, a small prism cutting tool includes a base plate 1, which is characterized in that: a mounting groove 2 is opened on the top outer wall of the base plate 1, two mounting frames 3 are placed inside the mounting groove 2, and a clamping plate 4 is rotatably connected inside the two mounting frames 3. An adjustment component 6 is installed at one end of the two mounting frames 3, and the adjustment component 6 includes a rotating frame 601 rotatably connected to the outer wall of one end of the mounting frame 3, the rotating frame 601 and the rotating end of the mounting frame 3 are coaxially fixed, a positioning rod 602 is slidably inserted at one end of the rotating frame 601, and the same spring 603 is fixedly connected between the positioning rod 602 and the rotating frame 601, and a plurality of positioning holes 604 are opened on the outer wall of one end of the mounting frame 3, and the positioning rods 602 can be inserted into the positioning holes 604.

[0025] The inclination of the two clamps 4 is adjusted according to the angle of the prism bevel, and one end of the positioning rod 602 is pulled to overcome the pulling force of the spring 603 and disengage from the positioning hole 604. Then, the clamp 4 is driven to flip in the mounting frame 3 through the rotating frame 601. When it reaches a suitable position, the positioning rod 602 is released, and the spring 603 can drive the positioning rod 602 to enter one of the limit grooves 801 again. At this time, the position of the clamp 4 will be fixed again to ensure that the eccentric prism can also be fixed.

[0026] like Figure 1 As shown in Figure 2, the two mounting frames 3 are installed with the same driving assembly 7, and the driving assembly 7 includes the same bidirectional screw 701 that is rotatably connected to the inner walls on both sides of the mounting groove 2. The two mounting frames 3 are respectively threadedly connected to the threads at both ends of the bidirectional screw 701. The two mounting frames 3 are slidably inserted with multiple limit rods 702, and the two ends of the two limit rods 702 are respectively fixedly connected to the inner walls on both sides of the mounting groove 2. A motor 703 is fixedly installed on the outer wall of one side of the base plate 1, and the rotating shaft of the motor 703 and the bidirectional screw 701 are coaxially fixed.

[0027] The inner walls at both ends of the mounting groove 2 are fixedly connected with a same placing plate 5, and the placing plate 5 is located in the gap between the mounting frame 3 and the clamping plate 4. Since the placing plate 5 is located in the gap between the mounting frame 3 and the clamping plate 4, the prism can be placed normally while the movement of the two clamping plates 4 will not be hindered, and then the prism is placed thereon.

[0028] The start motor 703 drives the bidirectional screw rod 701 to rotate, and the bidirectional screw rod 701 will drive the two mounting frames 3 restricted by the limit rod 702 to move closer to each other, and then the two clamping plates 4 will also move synchronously with the mounting frames 3, and the position of the prism will be firmly fixed.

[0029] like Figure 2 and Figure 3As shown, a reinforcement component 8 is installed in each of the two splints 4, and the reinforcement component 8 includes a limiting groove 801 opened on the inner wall of one side of the splint 4, and the top and bottom inner walls of the limiting groove 801 are fixedly connected with the same screw rod 802, and the screw rod 802 is threadedly connected with the same reinforcement plate 803, and the reinforcement plate 803 is in contact with the inner wall of the limiting groove 801.

[0030] A knob is rotatably connected to the outer wall of the top of the splint 4, and the knob is coaxially fixed with one end of the screw rod 802, which can increase the transmission force arm when driving the screw rod 802, thereby making the driving process easier.

[0031] If the prism is rectangular, after the two clamps 4 are attached to the two sides of the prism, the screw rod 802 is driven by the knob to rotate inside the limit groove 801, and the reinforcement plate 803 restricted by the limit groove 801 can be moved downward under the drive of the screw rod 802, and then the reinforcement plate 803 can be tightly attached to the upper surface of the prism, thereby reinforcing the prism, further increasing the stability of the prism when it is fixed.

[0032] like Figure 1 As shown in FIG. 2 , the top outer walls of the two clamping plates 4 are provided with a plurality of through grooves 605 , and the plurality of through grooves 605 on one side are staggered with each other so that the two clamping plates 4 can cross together, thereby enabling the device to adapt to the clamping work of prisms of different sizes.

[0033] like Figure 1 As shown in FIG. 2 , the lead angles of the threads at both ends of the bidirectional screw 701 and the threads of the two screws 802 are smaller than the equivalent friction angle, so that all three have self-locking properties.

[0034] The utility model provides a small prism cutting tool, and the specific working principle is as follows:

[0035] When the device is working, the inclination of the two clamping plates 4 is adjusted according to the angle of the prism bevel, and one end of the positioning rod 602 is pulled to overcome the pulling force of the spring 603 and disengage from the positioning hole 604, and then the clamping plate 4 is driven to flip in the mounting frame 3 through the rotating frame 601. When it reaches a suitable position, the positioning rod 602 is released, and the spring 603 can drive the positioning rod 602 to enter one of the limiting grooves 801 again. At this time, the position of the clamping plate 4 will be fixed again to ensure that the eccentric prism can also be fixed. Since the placement plate 5 is in the gap between the mounting frame 3 and the clamping plate 4, the prism can be placed normally while the movement of the two clamping plates 4 will not be hindered. Then the prism is placed on it, and the bidirectional screw rod 701 is driven to rotate by starting the motor 703. The bidirectional screw rod 701 will drive the two mounting frames 3 restricted by the limiting rod 702 to approach each other, and then the two clamping plates 4 will also move synchronously with the mounting frames 3, and the position of the prism will be firmly fixed. If the prism is rectangular, when the two clamping plates 4 are attached to the two sides of the prism, the screw rod 2 802 is driven by the knob to rotate inside the limiting groove 801, and the reinforcement plate 803 restricted by the limiting groove 801 can be moved downward under the drive of the screw rod 2 802, and then the reinforcement plate 803 can be tightly attached to the upper surface of the prism, so that the prism can be reinforced, further increasing the stability of the prism when it is fixed. When fixing the anisotropic prism, the reinforcement plate 803 can be adjusted to the top, and it can pass through the through groove 605, so that the reinforcement plate 803 will not affect the subsequent clamping work.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
