Description
Technical Field
[0001] The utility model relates to the technical field of processing equipment, in particular to a bevel turning fixture with a self-ejecting function. Background Art
[0002] During the bevel turning process of products, due to their special shapes, general machine tools cannot clamp and align them. Therefore, there is an urgent need for a fixture that is simple to manufacture, can quickly position and clamp, and is easy to operate to solve these problems. Summary of the Invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a bevel turning fixture with a self-ejecting function. The movable positioning pin of the fixture changes with the state of the positioning rotating plate. Initially, the movable positioning pin is stressed downward. When it rotates to the 180° position, the movable positioning pin can self-eject.
[0004] To achieve the above object, a bevel turning fixture with a self-ejecting function includes a machine tool spindle. The machine tool spindle is connected to a spindle connecting plate, and the spindle connecting plate is connected to a positioning rotating plate. One end of a movable positioning pin is embedded in the spindle connecting plate, and the other end of the movable positioning pin is connected to the positioning rotating plate. The positioning rotating plate is provided with an inclined groove on the side in contact with the spindle connecting plate. One end of the movable positioning pin inserts into or leaves the inclined groove. A spring is connected to the other end of the movable positioning pin, and the spring is embedded in a spring sleeve. The spring sleeve is fixed in a groove on one side of the spindle connecting plate. A product is connected to the positioning rotating plate, and the product is fixed to the positioning rotating plate through a pressing plate. A retaining ring is sleeved on the positioning rotating plate.
[0005] The positioning rotating plate rotates eccentrically around the spindle connecting plate.
[0006] An installation hole for the movement of the movable positioning pin is provided in the middle of the spindle connecting plate.
[0007] An installation groove for the installation of the positioning rotating plate is provided on one side of the spindle connecting plate.
[0008] A weight one and a weight two are provided on the side of the positioning rotating plate.
[0009] The weight one, the weight two, and the spring sleeve are all connected to the spindle connecting plate through bolts.
[0010] Compared with the prior art, the utility model can quickly position and clamp products. Through the inclined groove on the side of the positioning rotating plate, the positioning and fixing of the positioning rotating plate can be achieved at a fixed position.

Specific embodiments
[0017] The following further describes the present utility model with reference to the drawings.
[0018] As Figures 1 to 4 shown, the machine tool spindle is connected to the main shaft connecting plate 1, the main shaft connecting plate 1 is connected to the positioning rotating plate 2, one end of the movable positioning pin 7 is embedded in the main shaft connecting plate 1, the other end of the movable positioning pin 7 is connected to the positioning rotating plate 2, the positioning rotating plate 2 is provided with an inclined groove 13 on the side in contact with the main shaft connecting plate 1, one end of the movable positioning pin 7 is inserted into or leaves the inclined groove 13, the spring 9 is connected to the other end of the movable positioning pin 7, the spring 9 is embedded in the spring sleeve 8, the movable positioning pin 7 is switched and limited by the grooves with different depths on the left and right sides of the inclined groove 13, the movable positioning pin 7 realizes the position change and movement, and at the same time, the spring 9 assists to realize the self-pop-up function of the movable positioning pin 7 when the groove changes from a shallow groove to a deep groove, the spring sleeve 8 is fixed in the groove 12 on one side of the main shaft connecting plate 1, the product 10 is connected to the positioning rotating plate 2, the product 10 is fixed on the positioning rotating plate 2 through the pressure plate 4, and a retaining ring 3 is sleeved on the positioning rotating plate 2.
[0019] The positioning rotating plate 2 rotates eccentrically around the main shaft connecting plate 1.
[0020] The main shaft connecting plate 1 is provided with a mounting hole 11 for the movement of the movable positioning pin 7 in the middle, and the mounting hole 11 plays a guiding role for the movable positioning pin 7.
[0021] One side of the main shaft connecting plate 1 is provided with a mounting groove 14 for the installation of the positioning rotating plate 2.
[0022] The side of the positioning rotating plate 2 is provided with the first unbalanced weight 5 and the second unbalanced weight 6, and the first unbalanced weight 5 and the second unbalanced weight 6 change the axial position of the overall center of gravity of the positioning rotating plate 2, making it more convenient to rotate.
[0023] The first unbalanced weight 5, the second unbalanced weight 6 and the spring sleeve 8 are all connected to the main shaft connecting plate 1 through bolts.
[0024] During the implementation of the present utility model, first connect the main shaft connecting plate 1 to the machine tool main shaft, fix the positioning rotating plate 2 in the mounting groove 14 on one side of the main shaft connecting block 1, insert the movable positioning pin 7 into the mounting hole 11, then install a spring 9 and a spring sleeve 8 at the rear of the movable positioning pin 7, fix the spring sleeve 8 in the groove 12 of the main shaft connecting plate 1. After placing the product 10 on the main shaft connecting plate 1 to keep the product 10 in the same straight line as the center of the machine tool, fix the product 10 on the positioning rotating plate 2 with the pressing plate 4. The operator rotates the positioning rotating plate 2. As Figure 5 , the movable positioning pin 7 is squeezed and shrinks back into the spring sleeve 8 under the force of the shallow groove side of the internal inclined groove 13 of the positioning rotating plate 2. As Figure 4 , when the positioning rotating plate 2 rotates 180°, the inclined groove 13 against the movable positioning pin 7 turns to the deep groove side, and the movable positioning pin 7 automatically pops out without restriction, which restricts the positioning rotating plate 2. When there is no external force to rotate the positioning rotating plate 2, the movable positioning pin 7 fixes the positioning rotating plate 2, playing the role of quickly positioning and clamping product parts.
