Description

Technical Field

[0001] The utility model relates to the technical field of notebook shell stamping, in particular to a precision positioning jig for preventing loosening. Background Art

[0002] In recent years, laptop computers have been widely used due to their light weight, convenience and speed of use. They are increasingly developing towards exquisite miniaturization. As an important component of laptop computers, the laptop casing not only requires a flat and smooth surface shape, but also requires fast heat dissipation and a quick opening and closing device to make the laptop beautiful, heat-dissipating and easy to maintain. In the production process of laptop casings, stamping is one of the important processes. In order to improve the processing efficiency of laptop casings, a stamping structure is needed. However, the existing stamping structure still has the following shortcomings:

[0003] For example, the utility model with application number 202121656470.5 discloses a stamping device for notebook shells. This utility model overcomes the problem that the stamping device in the prior art has cumbersome operation of replacing the stamping head, which seriously affects work efficiency. In addition, the workpieces are generally picked up manually, and the temperature of the processed workpiece is high, which can easily burn employees, posing certain safety hazards. However, similar to the comparative documents of the above-mentioned application, when the existing notebook shell stamping device is used, since most notebook shells are directly placed on the surface of the stamping seat before processing and the stamping seat does not have a positioning structure, the notebook shell is easily displaced during the stamping process, which reduces the stamping accuracy, resulting in reduced practicality and reduced efficiency of the notebook shell stamping device.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a precision positioning fixture that prevents loosening is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a precision positioning fixture that prevents loosening, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precision positioning fixture for preventing loosening, comprising a workbench and a positioning assembly, a supporting column foot is installed at the bottom of the workbench, a positioning assembly is provided at the middle of the upper end of the workbench, and the positioning assembly includes a stamping seat, a mounting frame, a threaded through hole, a threaded rotating rod, an auxiliary turning handle, a movable shaft, a limit plate and an anti-slip rubber pad, mounting frames are installed on both sides of the upper end of the stamping seat, and a threaded through hole is opened at the upper end of the mounting frame, and a threaded rotating rod is connected to the inside of the threaded through hole, and an auxiliary turning handle is installed at the upper end of the threaded rotating rod, a movable shaft is connected to the front end of the threaded rotating rod, and a limiting plate is provided on the outside of the movable shaft, and an anti-slip rubber pad is added to the lower end of the limiting plate, and a processing assembly is provided above the workbench.

[0007] Furthermore, support vertical rods are installed on both sides of the upper end of the workbench, and a mounting horizontal plate is provided at the upper inner ends of the support vertical rods.

[0008] Furthermore, the mounting bracket is L-shaped and is threadedly connected to the stamping seat.

[0009] Furthermore, the outer dimensions of the threaded rotating rod match the inner dimensions of the threaded through hole, and the threaded rotating rod is rotatably connected to the mounting bracket through the threaded through hole.

[0010] Furthermore, the processing assembly includes a hydraulic rod, a punching head and a movable slide. The punching head is installed at the front end of the hydraulic rod, and movable slides are installed on both sides of the outside of the punching head.

[0011] Furthermore, the processing assembly also includes a limiting through hole, a limiting rod and a mounting seat, and a limiting through hole is opened inside the front end of the movable slider, and a limiting rod is connected inside the limiting through hole, and mounting seats are provided at both ends of the limiting rod.

[0012] Furthermore, the hydraulic rod and the punching head are distributed vertically, and the hydraulic rod and the punching head are threadedly connected.

[0013] Furthermore, the inner dimensions of the limiting through hole match the outer dimensions of the limiting rod, and the movable slider is slidably connected to the limiting rod through the limiting through hole.

[0014] The utility model provides a precision positioning fixture to prevent loosening, which has the following beneficial effects:

[0015] 1. The utility model is provided with a positioning component. When using a precision positioning jig to prevent loosening, the positioning component provided at the middle upper end of the workbench is used to avoid that most notebook shells are placed directly on the surface of the stamping seat before processing and the stamping seat does not have a positioning structure, which causes the notebook shell to be easily displaced during the stamping process, resulting in a decrease in stamping accuracy and a decrease in the practicality of the notebook shell stamping device. The stamping seat is fixedly installed in the middle upper end of the workbench by fasteners, and the mounting frame is fixedly installed on both sides of the upper end of the stamping seat with the help of fasteners. The internal size of the threaded through hole opened at the upper end of the mounting frame matches the external size of the threaded rotating rod, and then the threaded rotating rod is rotated and installed into the mounting frame through the threaded through hole. The limit plate is limitedly installed at the front end of the threaded rotating rod by a movable shaft. The auxiliary handle is rotated to move the limit plate at the front end of the threaded rotating rod, and the anti-slip rubber pad added at the front end of the limit plate increases the friction between it and the notebook shell, thereby better limiting the notebook shell to prevent it from loosening and displacement, thereby improving the efficiency of using the tight positioning jig.

[0016] 2. The utility model can avoid the poor stability of the stamping structure in most positioning jigs when using the anti-loosening precision positioning jig through the setting of the processing components arranged above the workbench, which makes the stamping head easy to shift in position and affect the processing yield rate, resulting in reduced efficiency of the positioning jig. The hydraulic rod is fixedly installed on both sides of the inner side of the mounting cross plate by fasteners, and the stamping head is fixedly installed on the front end of the hydraulic rod with the help of fasteners. The operation of the hydraulic rod drives the stamping head to move in position, so that the movable sliders installed on both sides of the outside of the stamping head move in position accordingly. The limit rod is fixedly installed on the inner side of the supporting vertical rod by the mounting seat and the fastening bolts. The internal size of the limit through hole opened inside the front end of the movable slider matches the external size of the limit rod, and then the stability of the movable slider during movement is increased by cooperating with the limit rod through the limit through hole, thereby avoiding positional deviation of the stamping head during movement, improving the stability of the positioning jig during processing, and thus increasing the overall processing yield rate.
