Detailed Description
The technical scheme of the application is further described and illustrated below by combining with the embodiment.
Example 1: a positioning device used in the lamp tube processing process comprises a body 1, wherein one end of the body 1 is provided with a positioning hole 2, and a chuck hole 5 is processed on the body 1 at one side opposite to the positioning hole 2; the body 1 is also provided with an air cylinder 18, and the air cylinder 18 is connected with the guide rod 3; the inner surface of the chuck hole 5 is embedded with an inner liner 4, the bottom of the chuck hole 5 is provided with a positioning disc body 10, the positioning disc body 10 is coincident with the central axis of the chuck hole 5, a processing hole 9 is formed in the central axis of the positioning disc body 10, and three clamping claws 8 hinged to the positioning disc body 10 are uniformly distributed on the periphery of the processing hole 9; the claw 8 is meshed with the inner tooth of the transmission gear ring 16, and the outer tooth of the transmission gear ring 16 is meshed with the rack structure 17 on the guide rod 3; the transmission gear ring 16 is positioned in the inner lining ring 4. The positioning disk body 10 comprises an outer ring part 10 and a positioning part 13, and a cooling part 12 of a sealing structure is formed between the outer ring part 10 and the positioning part 13 through a plate body 14; the cooling part 12 is provided with a liquid inlet pipe 7 and a liquid outlet pipe 6. The outer ring part 10 is provided with a plurality of arc holes 11, and the outer ring part 10 is connected with the body 1 through the arc holes 11 and the fastening screws. And limit strips 15 are arranged on the upper side and the lower side of the guide rod 3. The number of the positioning holes 2 is 3, and the positioning holes are distributed on the body 1 in a triangular shape.
As shown in fig. 3, in the present invention, the body 1 has an irregular polygonal structure, and three positioning holes 2 distributed in a triangle shape are machined at one end of the body, and the positioning holes 2 with the triangle structure can ensure the stability of the structure in the use process, and the horizontal position deviation can not occur. A chuck hole 5 for positioning the disk body 10 is installed at the bottom of the body 1 at one end opposite to the positioning hole 2. The inner surface of the chuck hole 5 is an inner ring 4. In the direction shown in fig. 3, the left side of the lining ring 4 is provided with a notch which is the same as the through hole provided with the guide rod 3, and can meet the engagement of the rack part on the guide rod 3 with the transmission gear ring 16 in the chuck hole 5. For ease of understanding, the structure of the inner liner 4 is illustrated in fig. 4.
Specifically, a movable guide rod 3 is installed in the body 1, and the guide rod 3 is connected with the air cylinder 18 and moves under the driving of the air cylinder 18. The guide rod 3 is of a cylindrical structure, and limit strips 15 are machined at the upper end and the lower end of the cylindrical structure, and the limit strips 15 can ensure the accuracy of the displacement of the guide rod 3, so that a rack structure 17 on the guide rod 3 can be meshed with external teeth of the transmission gear ring 16.
The guide rod 3 can be extended and retracted into the body 1 under the driving of the cylinder 18, and the rotation of the transmission gear ring 16 is realized during the extension and retraction. The transmission gear ring 16 can drive the claw 8 engaged with it via the internal teeth.
