DETAILED DESCRIPTION

[0028] The principles and features of the present invention are described below in conjunction with embodiments; the examples given are only used to explain the present invention; they are not used to limit the scope of the present invention.

[0029] A sawing platform with adjustable angle comprises a guide sleeve 1, a tile plate 3 and a rotating platform 4.

[0030] The guide sleeve 1 is cylindrical, and an outer wall 6 and an inner wall 7 are formed on the upper part of the guide sleeve 1. The inner wall 7 is set in the outer wall 6, and a chamber 8 is formed between the outer wall 6 and the inner wall 7. The chamber 8 is annular. The tile plate 3 is embedded in the guide sleeve 1, that is, the tile plate 3 is arranged in the chamber 8. The tile plate 3 is arc-shaped, and multiple tile plates 3 are arranged in a circumferential array. In this embodiment, a total of 12 tile plates 3 are arranged, and the center angle of each tile plate 3 is 30°. The upper surface of the guide cylinder 1 is provided with a guide groove 2 along the circumferential array, one side of the guide groove 2 is vertical, and the other side of the guide groove 2 is inclined. The guide groove 2 corresponds to the tile plate 3 one by one, that is, the center angle of the guide groove 2 is 30°. The tile plate 3 slides up and down in the chamber 8. The tile plate 3 can slide upward until its upper surface is flush with the upper surface of the guide sleeve 1, and the tile plate 3 can slide downward until its upper surface slides downward to below the bottom surface of the guide groove 2. The outer wall 6 of the guide sleeve 1 is provided with a fixing groove 9, which extends along the sliding direction of the tile plate 3 and is arranged in a circumferential array along the guide sleeve 1. The tile plate 3 is connected with a set screw 10, which passes through the fixing groove 9 and extends to the outside of the guide sleeve 1. The tile plate 3 can be relatively fixed to the guide sleeve 1 through the set screw 10.

[0031] The bottom surface of the rotating platform 4 is connected with a support rod 16, which extends downward to the outside of the guide sleeve 1 and is rotatably connected to the guide sleeve 1. The bottom surface of the rotating platform 4 is connected with a telescopic rod 5, and the bottom surface of the telescopic rod 5 is pressed and connected with the guide surface of the guide groove 2. Specifically, the telescopic rod 5 includes an outer rod 11, an inner rod 12 and a spring 13, one end of the outer rod 11 is fixedly connected to the rotating platform 4, one end of the inner rod 12 extends to the other end of the outer rod 11, and the other end of the inner rod 12 is provided with a ball 14, and the ball 14 rolls along the guide groove 2. The spring 13 is provided in the outer rod 11 and the inner rod 12. Under the action of the spring 13, the outer rod 11 and the inner rod 12 have a movement tendency to separate from each other. The bottom of the telescopic rod 5 is connected with a roller 15, and the roller 15 has two rollers, and the two rollers 15 are respectively placed on both sides of the ball 14, wherein the ball 14 can press on the upper surface of the tile plate 3, and the two rollers 15 press on the guide groove 2 of the inner wall 7 and the outer wall 6 respectively.

[0032] The upper surface of the rotating platform 4 is provided with a card slot 17 along a circumferential array, and the card slot 17 extends along the radial direction of the rotating platform 4. A card block 18 is slidably connected in the card slot 17, and a pin 19 is connected to the card block 18. The card block 18 can be relatively fixed to the rotating platform 4 through the pin 19. The card block 18 is used to fix the workpiece. The guide sleeve 1 is fixedly connected to the indexing plate 20, and the rotating platform 4 is connected to the indicator plate 21. The indicator plate 21 is opposite to the indexing plate 20 up and down, so as to mark the rotation angle of the rotating platform 4 and the guide sleeve 1.

[0033] The working principle of this device is:

[0034] (1) When all the tiles 3 slide upward to the limit position, the rotating platform 4 realizes the positioning of the rotation angle through the indexing plate 20 and the indicator plate 21;

[0035] (2) When processing as attached Fig. 9 The workpiece shown in the figure is characterized in that the sawing holes are arranged in a uniform array along the circumference. In this embodiment, the center angle between adjacent sawing holes is 90°. The four tiles 3 with a center angle of 90° are slid downward to the lowest limit position. At this time, whenever the telescopic rod 5 moves to the sliding tile 3, the telescopic rod 5, which was originally in a compressed state, stretches, and the roller 15 collides with the guide groove 2 to produce a sound. The operator rotates the rotating platform 4 in the opposite direction to make it close to the vertical edge of the guide groove 2, and the positioning is completed. Similarly, this workpiece is also suitable for the case where the center angles of adjacent sawing holes are 30°, 60°, and 180°.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
