Technical Field

[0001] The utility model relates to the field of clamps, in particular to a telecentric lens quick disassembly and assembly clamp. Background Art

[0002] The device used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position to accept construction or inspection is also called a fixture. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process of the process can be called a fixture. Telecentric lenses are mainly designed to correct the parallax of traditional industrial lenses. They can keep the image magnification unchanged within a certain range of object distances. This is a very important application when the objects being measured are not on the same object plane. Telecentric lenses have always been favored by machine vision applications that have high requirements for lens distortion due to their unique parallel optical path design.

[0003] A Chinese patent discloses a telecentric lens (authorization announcement number CN 206804980 U). The patented technology can shorten the axial length of the telecentric lens by 50% without affecting the imaging quality and the object field of view. However, the installation and disassembly of the telecentric lens is very cumbersome. Therefore, a telecentric lens quick disassembly and assembly fixture is proposed for the quick disassembly, installation and replacement of the telecentric lens of the equipment.

[0004] Therefore, those skilled in the art provide a telecentric lens quick disassembly and assembly fixture to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0019] Example 1

[0020] See also Figures 1 to 7In the present embodiment, a quick disassembly and assembly fixture for a telecentric lens is provided, comprising a fixture 1, a vertical plate 2 and a base 5. Fixed blocks 7 are arranged at the four corners of the bottom of the base 5. Anti-skid pads 8 are arranged at the lower ends of the fixed blocks 7. Two vertical plates 2 are arranged symmetrically with each other. A clamping groove is arranged between the two vertical plates 2. A protective pad 3 is arranged inside the clamping groove. A groove body 4 is arranged inside the vertical plate 2. Slide grooves 6 are arranged inside the base 5 and on both sides of the outside of the vertical plate 2. A screw 11 is passed through the slide groove 6. A handle is fixed on the outside of the screw 11. A telecentric lens 9 is placed and clamped inside the clamping groove. The bottom of the telecentric lens 9 is fixed with a connecting sleeve 10, a screw rod 11 is threadedly connected to a slider 12, a horizontal plate 13 is arranged on the top of the slider 12, and a connecting rod 14 is connected to the right side of the horizontal plate 13. There are four connecting rods 14, which are symmetrically arranged. An arc-shaped clamping plate 15 is arranged at the end of the connecting rod 14. There are two arc-shaped clamping plates 15, and the arc-shaped clamping plates 15 are placed inside the groove body 4 for sliding connection. By setting the groove body 4, the arc-shaped clamping plate 15 slides more stably inside the groove body 4. A protective pad 16 is arranged inside the clamping groove. There are two protective pads 16, which are convenient for telecentric lens 9. The lens 9 is protected. When in use, the telecentric lens 9 is first placed inside the clamping groove, and the rotating handle is turned to drive the screw 11 to rotate clockwise. At this time, the sliders 12 approach each other. Since the sliders 12 are slidably connected to the slide groove 6, the sliders 12 drive the internal arc-shaped clamping plates 15 to slide left and right, so that the arc-shaped clamping plates 15 are away from or close to the telecentric lens 9. At this time, the telecentric lens 9 is set between the two arc-shaped clamping plates 15, and then the rotating handle is rotated in the opposite direction to move the two arc-shaped clamping plates 15 toward each other, thereby realizing the disassembly of the telecentric lens 9, and the sliders The design of 12 and the slide groove 6 can make the arc clamping plate 15 move and adjust laterally, and the lateral movement of the arc clamping plate 15 realizes the adjustment clamping, so that the telecentric lens 9 can be easily and quickly disassembled and assembled, which greatly simplifies the disassembly and assembly steps, and provides a simpler and faster solution for replacing the telecentric lens 9 in practical applications, shortens the time consumed in replacing the telecentric lens 9, and has high work efficiency. At the same time, the setting of the groove body 4 is conducive to improving the stability of the clamping of the telecentric lens 9 and locking it firmly. Through the setting of the protective pad 1 3 and the protective pad 2 16, it is more convenient to protect the telecentric lens 9, and the protective effect is good.

[0021] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.
