Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a fit detection device. Background Art

[0002] With the rise of online shopping, companies are shipping some low-space-efficiency products as semi-finished products to save on logistics costs. Floor fans are a typical example. To maximize space utilization, floor fans are typically packaged after the four main components are assembled. Assembly of the electrical box and pipe assembly is typically completed by the customer. The electrical box itself is an injection-molded part, susceptible to various factors during the molding and cooling process, resulting in a high rejection rate. To ensure product quality, each electrical box and pipe assembly must function properly. For a long time, testing was performed using a simple, real-world assembly of the electrical box and pipe assembly. However, this method is not only inefficient but also only verifies that the electrical box and pipe assembly can be assembled, not that they are properly assembled, making it impossible to completely eliminate defective products. Summary of the Invention

[0003] The object of the present invention is to provide a fit detection device to solve the technical problem of low efficiency of actual assembly detection in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] The present invention provides a fit detection device, which comprises a workbench and a simulated fit body mounted on the workbench and having the same shape as the fit piece. The fit between the part to be detected is detected by assembling the part to be detected on the simulated fit body.

[0006] As a further improvement of the present invention, the present invention further includes a guide body installed on the workbench for guiding the component to be inspected during the assembly process.

[0007] As a further improvement of the present invention, the guide body includes a seat body, a support leg arranged at the bottom of the seat body, and a guide hole arranged on the seat body and coaxial with the simulation matching body.

[0008] As a further improvement of the present invention, the guide hole is an inverted frustum-shaped hole, the specifications of the top large end are larger than the specifications of the simulated ligand, and the specifications of the bottom small end are equal to or slightly larger than the specifications of the simulated ligand.

[0012] As a further improvement of the present invention, it further includes a control module and an indicator light arranged on the workbench, and the control module is electrically connected to the limit switch and the indicator light respectively.

[0013] As a further improvement of the present invention, the simulated fitting body is in a cylindrical shape, and the limit switch is installed at the lower part or bottom of the simulated fitting body.

[0014] As a further improvement of the present invention, the simulated ligand and the workbench are connected in a detachable manner.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The fit detection device provided by the present invention can be used for fit detection of electrical boxes and pipe assemblies. By replacing the pipe assembly with a simulated fitting body, there is no need to manually hold the pipe assembly with one hand and the electrical box with the other hand for assembly. When using the fit detection device of the present invention, the simulated fitting body replacing the pipe assembly is fixed on a workbench.

[0021] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0022] like Figure 1 As shown, the present invention provides a fit detection device, comprising a workbench 1 and a simulated fitting body 2 mounted on the workbench 1 and having the same shape as the fitting part. The fit between the part to be detected is detected by assembling the part to be detected on the simulated fitting body 2.

[0023] It should be noted here that the matching parts in the present invention are pipe assemblies, and the component to be tested is an electrical box. The fit detection device in the present invention can detect the fit between the electrical box and the pipe assembly to ensure that each electrical box is of qualified quality before leaving the factory.

[0024] The following is a specific description using an electrical box as an example of the component to be inspected.

[0025] As an optional embodiment of the present invention, a guide body 3 is further included which is installed on the workbench 1 to guide the electrical box during assembly.

[0026] By providing the guide body 3, the electrical box can be guided so that the electrical box can be assembled with the simulated matching body 2 quickly and efficiently, thereby further improving the assembly efficiency.

[0027] Furthermore, the guide body 3 includes a base body, a support leg arranged at the bottom of the base body, and a guide hole arranged on the base body and coaxial with the simulated matching body.

[0028] As an optional embodiment of the present invention, the guide hole is an inverted frustum-shaped hole, the specifications of the top large end are larger than the specifications of the simulated ligand 2, and the specifications of the bottom small end are equal to or slightly larger than the specifications of the simulated ligand 2.

[0029] It should be noted here that "slightly larger" means that the specification of the small opening at the bottom is within 10 mm larger than the specification of the simulated ligand 2.

[0030] As another optional embodiment of the present invention, the guide hole is an equal diameter through hole with a specification equal to or slightly larger than the specification of the simulated ligand 2. The "slightly larger" here means that the guide hole specification is larger than the specification of the simulated ligand 2 by less than 10 mm.

[0031] As an optional embodiment of the present invention, a limit switch 4 for detecting whether the fitting is in place is provided on the simulated fitting body 2 corresponding to the optimal assembly position.

[0032] Furthermore, the optimal assembly position referred to here refers to the optimal depth of the electrical box inserted into the simulated fitting body 2, that is, the position where the electrical box is assembled in place. The optimal assembly position is determined according to the actual situation of electrical boxes of different types or specifications.

[0033] In order to improve the application range of the product, the number of the simulated ligands 2 is at least one, and each simulated ligand 2 has different specifications and is used to replace fittings of different specifications.

[0034] To enhance the product's automation level, the system also includes a control module, a main switch, and an indicator light 5, mounted on workbench 1. The main switch is electrically connected to the control module, which in turn is electrically connected to the limit switch 4 and indicator light 5, respectively. A detection circuit is provided within workbench 1, connecting the main switch, limit switch 4, indicator light 5, and control module to form a signaling circuit. This circuit can be implemented using existing products. When the electrical box is fully inserted and contacts the limit switch 4, the limit switch 4 sends a signal to the control module, which in turn sends a signal to the indicator light 5. The indicator light illuminates, indicating that the box is fully inserted.

[0035] The simulated fitting body 2 is cylindrical in shape, and the limit switch 4 is installed at the lower part or bottom of the simulated fitting body 2.

[0036] Furthermore, the simulated fitting body 2 is detachably connected to the workbench 1. The detachable connection allows for easy replacement of simulated fitting bodies 2 of different specifications, thereby completing the matching test process for electrical boxes of different specifications.

[0037] Among them, the detachable connection method can be realized by plugging.

[0038] Example 1:

[0039] The present invention provides a floor fan electrical box fit detection device, which mainly solves the tedious problem of physical fit detection. It uses a simulated fitting body 2 to replace other parts in the physical object that need to be matched with the electrical box to detect the fit of the floor fan electrical box, and adds a limit switch 4 at the optimal fit position to detect whether the electrical box and its matching parts can achieve the best fit. The simulated fitting body 2 and the guide body 3 in the fit detection device of the present invention must be matched with the floor fan electrical box, so its specific structural dimensions must be designed according to the structure of different models of floor fan electrical boxes; the power box, limit switch 4, main switch and indicator light 5 in the workbench 1 constitute the signal expression circuit of the device, which is used to indicate the detection results. Before using the device, the main switch in the signal expression circuit must first be in a closed state so that the entire signal expression circuit is in a detection state. At this time, the inspector will place the floor fan electrical box to be inspected above the simulated fitting body 2 under the guidance of the guide body 3. If the size of the electrical box to be inspected meets the expected assembly requirements, the electrical box will be able to cooperate with the simulated fitting body 2 and continue to move downward. If the electrical box can reach the optimal cooperation position with the simulated fitting body 2, the limit switch 4 will be triggered to make the entire signal expression circuit in the on state, and the indicator light 5 will light up, indicating that the test is qualified; if the size of the electrical box cannot meet the requirements for optimal cooperation with the simulated fitting body 2, the electrical box will not be able to stimulate the limit switch 4 in the optimal cooperation position, and the indicator light 5 will not light up, indicating that the test is unqualified.
