Description

Technical Field

[0001] The invention relates to the technical field of positioning fixtures, and in particular to a positioning fixture used for processing LED lamps. Background Art

[0002] LED lamps are becoming the main products of the new generation lighting market with their technical characteristics such as high efficiency, energy saving, safety, long life, compactness and clear light, and are effectively driving the rapid development of the environmental protection and energy-saving industry. During the production process of LED lamps, stamping equipment or drilling equipment is needed to process the shell and parts. In order to make the processing more convenient, fixtures are used to clamp and fix the LED lamps. However, in the prior art, the steps of using the fixture generally include installation, processing, disassembly and replacement of parts and re-installation. Processing cannot be performed during the installation and disassembly process of LED lamps, which affects the processing efficiency.

[0003] To this end, the Chinese patent with the publication number "CN220073918U" announced "a positioning fixture for processing LED lamps", whose main structure includes the main body of the positioning fixture for processing LED lamps, a fixture mounting seat, a rotating fixture welding assembly, a positioning fixture assembly, a welding plate unit and a driving rotating unit. The positioning fixture for processing LED lamps is conveniently fixed and installed with the processing table of the LED lamp processing equipment through bolt mounting holes arranged on both sides of the fixture mounting seat. The welding parts connect the two sets of LED lamp placement plates. When the LED lamps on one side are processed, the other side is in an idle state to facilitate the disassembly and assembly of the LED lamps. After the processing is completed, the motor drives the welding parts to rotate, so that the position of the LED lamp placement plate is reversed, so that the processing and disassembly can be carried out simultaneously, thereby improving the processing efficiency.

[0004] The above-mentioned positioning fixture for processing LED lamps utilizes multiple synchronously moving clamping plates to clamp the LED lamps. However, many LED lamps are not designed with symmetrical structures, and the synchronously moving clamping plates can only clamp symmetrical LED lamps, which leads to large limitations in its use. At the same time, the clamping is a hard contact, which can easily cause clamping dents on the surface of the lamp or even cause serious damage to the lamp, and the protection ability of the lamp during use is relatively poor.

[0016] Compared with the prior art, the present invention provides a positioning fixture for processing LED lamps, which has the following beneficial effects: 1.

At the same time, the part in contact with the LED lamp is an elastic diaphragm, which has a strong surface bending ability, thereby reducing the pressure of the unit contact surface on the LED lamp, so as to improve the protection ability of the LED lamp in the clamping state; 2. By setting a threaded adjustment mechanism, each No. 2 rotating shaft is rotated to drive the external threaded rod to rotate. Under the influence of the threaded structure, the threaded sleeve will move along a straight line pointing to the axis of the horizontal support plate, thereby changing the distance between each elastic diaphragm and the clamped LED lamp. Since it has a separate adjustment function, it can independently adjust the corresponding clamping position according to the different structural shapes of the LED lamp to improve the use range of the equipment; 3.

The elastic diaphragm has a strong bending deformation ability, thereby increasing the contact area between the clamped part and the LED lamp, reducing the pressure within the unit clamping area, and achieving a flexible clamping and positioning effect on the LED lamp. When the gas pressure is greater than the elastic strength of the coil spring, the valve plate will move upward, and the high-pressure gas will leak out through the gap between the components, thereby preventing the LED lamp from being clamped and damaged due to excessive clamping force caused by excessive gas pressure. Of course, the elastic strength of the coil spring needs to be less than the maximum clamping pressure of the LED lamp, so as to form an effective protection capability for the LED lamp.

The bottom surface of the valve plate 711 is embedded with an annular gas sealing ring 712 which can prevent gas from leaking along the structural gap. In order to prevent gas leakage, it is necessary to make the bottom of the annular gas sealing ring 712 protrude downward relative to the bottom surface of the valve plate 711. The structural radius of the inner ring of the annular gas sealing ring 712 is larger than the structural radius of the No. 1 gas flow hole 79, and the structural radius of the outer ring of the annular gas sealing ring 712 is smaller than the distance between the gas flow groove 713 and the axial center line of the valve plate 711, and the active cavity 710 of the No. 3 component is provided with a coil spring 714 at the top of the valve plate 711, and the bottom end of the coil spring 714 abuts against the upper surface of the valve plate 711, and the top end abuts against the top end of the active cavity 710 of the No. 3 component, and the initial length of the coil spring 714 is larger than the height of the active cavity 710 of the No. 3 component.

[0025] In order to achieve the multi-angle adjustment capability of the clamping position, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 8, it is necessary to set up an angle-adjustable connecting mechanism 8, which is internally provided with a hemispherical hollow shell 81 that can be fixedly installed on the surface of the fixed component, a rotating ball head 87 rotatably placed inside the hemispherical hollow shell 81 and capable of driving the horizontal support plate 1 to rotate, and a fan-shaped brake rubber bag 86 that is placed in a compressed state between the hemispherical hollow shell 81 and the rotating ball head 87 and can keep the rotating ball head 87 stable when not affected by human power. The bottom fixing plate 83 is fixedly installed on the fixed surface, and then the working angle of the horizontal support plate 1 is manually adjusted. Due to the action of the fan-shaped brake rubber bag 86, the horizontal support plate 1 can be kept working at a fixed angle.

[0026] For the specific structure of the angle-adjustable connecting mechanism 8, please refer to Figure 8 , comprising a hemispherical hollow shell 81, the bottom of the hemispherical hollow shell 81 is provided with a bottom protruding column structure 82 of an integral structure therewith, the bottom end of the bottom protruding column structure 82 is provided with a bottom fixing plate 83 of an integral structure therewith, the interior of the hemispherical hollow shell 81 is provided with a spherical mounting groove 84 with an open top, the hemispherical hollow shell 81 is provided with a semi-fan-shaped embedding groove 85 on the periphery of the middle area of ​​the spherical mounting groove 84, the hemispherical hollow shell 81 is provided with a fan-shaped brake rubber bag 86 on the interior of the semi-fan-shaped embedding groove 85, the hemispherical hollow shell 81 is provided with a fan-shaped brake rubber bag 86, the hemispherical hollow A rotatable rotating ball head 87 is placed inside the spherical mounting groove 84 of the outer shell 81.

Due to the effect of the fan-shaped brake rubber bag 86, the horizontal support plate 1 can be kept working at a fixed angle; The LED lamps are held in the central area of ​​the plurality of longitudinal hollow columns 71, and then the second rotating shafts 68 are rotated, thereby driving the external threaded rods 66 to rotate. Under the influence of the thread structure, the threaded sleeve 61 moves along a straight line pointing to the axis of the horizontal support plate 1, thereby changing the distance between each elastic diaphragm 78 and the clamped LED lamps; Finally, the air pressure system is started to allow high-pressure gas to enter the interior of each No. 2 component active cavity 73. Under the influence of the high-pressure gas, the elastic diaphragm 78 undergoes expansion deformation, so that the elastic diaphragm 78 fits the outer surface of the LED lamp.

Of course, the elastic strength of the coil spring 714 needs to be less than the maximum clamping pressure of the LED lamp, thereby forming an effective protection capability for the LED lamp. After the work is completed, the high-pressure gas is allowed to flow back, and the clamped LED lamp can be taken out.
