Description

Technical Field

[0001] This utility model relates to the field of control board testing fixture technology, specifically a valve body program control board testing fixture. Background Technology

[0002] An electric valve controller is an industrial control device used in conjunction with an electric valve actuator. It is mainly used for remote or on-site control of valve opening, closing and regulation. The two exchange data through a communication circuit according to a communication protocol. Before the product leaves the factory, it is necessary to test whether the drive board, power board and display control board can communicate normally.

[0003] Chinese Utility Model Patent Publication No. CN210895122U discloses a control board testing fixture, comprising a fixture body, an analog sensor socket and at least one communication port pluggable to the control board under test, the analog sensor socket being connected to the communication port, and an automatic testing module or a functional simulation module. The automatic testing module is connected to the communication port and is used to receive output commands from the control board under test, or to generate analog operation input signals and send them to the control board under test. The functional simulation module includes an input analog switch, which is mounted on the fixture body and connected to the corresponding communication port; and an output analog display module, which is mounted on the fixture body and connected to the corresponding communication port. This utility model's control board testing fixture allows for simple redesign and replacement of the analog sensors when the functional requirements of the control board under test change, eliminating the need for complete scrapping of the testing fixture, thus shortening the testing cycle and reducing development costs.

[0004] While the aforementioned equipment can effectively test the control board, it lacks a mechanism for positioning and protecting the wiring harnesses used in the test fixture. This results in a large number of wiring harnesses at the test station, which not only hinders operators from testing the control board but also easily leads to wear on the wiring harness insulation, affecting the equipment's usability. Therefore, we propose a valve body program control board test fixture. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a valve body program control board test fixture to solve the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve body program control board test fixture, including a frame assembly, a detection assembly, a wiring assembly one, and a wiring assembly two, wherein the frame assembly includes a base, and a mounting bracket is fixedly mounted on the top of the base; The detection assembly includes a lifting plate, and the top of the mounting frame is fixedly equipped with an output shaft and a cylinder fixedly equipped with the top of the lifting plate. The wiring assembly includes a housing, a sealing plate on the outer wall of the housing, screws on the outer wall of the sealing plate, an mounting plate fixedly mounted on the inner wall of the housing, a groove on the top of the mounting plate, a limiting seat slidably connected to the inner wall of the groove, a movable plate fixedly mounted on the top of the limiting seat, a storage groove on the outer wall of the movable plate, a positioning plate fixedly mounted on the side wall of the movable plate near the sealing plate, an adjusting screw on the outer wall of the positioning plate, an arc-shaped plate rotatably connected to the end of the adjusting screw near the mounting plate, an adjusting screw two at the bottom of the movable plate, and a pressing plate rotatably connected to the top of the adjusting screw two. The second wiring assembly includes a protective shell that is fixedly assembled to the top of the mounting bracket, and a guide rod is also fixedly assembled to the top of the mounting bracket.

[0007] Through the above technical solution, by setting up a frame assembly, a detection assembly, a wiring assembly, a housing, a sealing plate, screws, a mounting plate, a moving plate, a storage slot, an adjusting screw, and an arc-shaped plate structure, the user can place the wire harness in the storage slot during use, and then rotate the adjusting screw to make the outer wall of the arc-shaped plate fit tightly against the wire harness, thereby evenly fixing the wire harness in the housing, making it easier for the user to organize the wire harness, and thus improving the practicality of the test fixture.

[0008] Preferably, the top of the extrusion plate is tightly fitted to the bottom of the mounting plate, and both the limiting seat and the moving plate are fixedly connected to the mounting plate through the extrusion plate.

[0009] Through the above technical solution, the extrusion plate and mounting plate structure allows the user to detach the extrusion plate from the bottom of the mounting plate by rotating the second adjusting screw during use. This facilitates the user to adjust the spacing between several moving plates, making it easier to fix wire harnesses of different diameters. This increases the range of applications for the wire harnesses in the test fixture, makes it easier for the user to operate, and further improves the practicality of the test fixture.

[0010] Preferably, a wire harness is placed on the inner wall of the storage slot, and the wire harness is fixedly connected to the mounting plate through an arc-shaped plate.

[0011] Through the above technical solution, the installation plate and arc-shaped plate structure make it possible for the user to move the arc-shaped plate laterally simply by rotating the adjusting screw during the use of the test fixture. This facilitates the user in clamping wire harnesses of different diameters, thereby ensuring the stability of the wire harnesses during the use of the test fixture.

[0012] Preferably, the number of movable plates is several, and the several movable plates are evenly distributed along the outer wall of the mounting plate.

[0013] Through the above technical solution, by setting up several movable plate structures, the test fixture can fix several wire harnesses through the shell and movable plates during operation, thereby ensuring that the appearance of the test fixture does not have too many messy wire harnesses, thus making it easier for users to operate the fixture and also optimizing the aesthetics of the test fixture.

[0014] Preferably, the outer wall of the guide rod is tightly fitted to the outer wall of the wire harness, and the end of the wire harness near the cylinder is fixedly connected to the mounting bracket through a protective shell.

[0015] The above technical solution uses a guide rod structure to guide the wire harness, making it easier for the user to insert the wire harness into the protective housing. The protective housing then protects the wire harness, preventing prolonged exposure to the outside environment and thus avoiding increased wear on the insulation layer. This improves the protective effect of the test fixture on the wire harness.

[0016] Preferably, the number of housings is four, and the four housings are evenly distributed along the top of the base.

[0017] Through the above technical solution, the four housing structures allow the wiring harnesses used for the cylinders and circuit components inside the test fixture to be routed through different housing positions, thereby facilitating user assembly of the test fixture and further improving its practicality.

[0018] Preferably, the bottom of the movable plate has a through hole, and the inner wall of the through hole is threadedly connected to the outer wall of the adjusting screw.

[0019] Through the above technical solution, by setting through holes and adjusting screw two structure, when the user rotates adjusting screw two, the top of the extrusion plate will disengage from the bottom of the mounting plate, so that the end of the moving plate away from the limit seat will not exert a pulling force on the limit seat, thereby allowing the limit seat to slide along the inner wall of the slide groove, realizing the effect of facilitating the user to adjust the distance between several moving plates, thus ensuring the normal use of the test fixture.

[0020] Compared with the prior art, this utility model provides a test fixture for a valve body program control board, which has the following advantages: 1. This valve body program control board test fixture, through its frame assembly, detection assembly, wiring assembly, housing, sealing plate, protective shell, adjusting screw, and arc-shaped plate structure, allows the user to fix the arc-shaped plate tightly against the wire harness by rotating the adjusting screw during use. Simultaneously, the protective shell protects the wire harness, preventing excessive wear of the insulation layer, thus facilitating user operation and improving the efficiency of both the user and the test fixture.

[0021] 2. The valve body program control board test fixture, through the setting of limit seats, moving plates, slides, adjusting screw two, and extrusion plate structure, allows the user to detach the extrusion plate from the bottom of the mounting plate by rotating the adjusting screw two when installing the wire harness. This facilitates the user to adjust the spacing between several moving plates, making it easier to fix wire harnesses of different diameters, thereby improving the fixing range and application range of the test fixture for wire harnesses.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5As shown, a valve body program control board test fixture includes a frame assembly 1, a detection assembly 2, a wiring assembly 3, and a wiring assembly 4. The frame assembly 1 includes a base 101, and a mounting bracket 102 is fixedly mounted on the top of the base 101. The detection component 2 includes a lifting plate 201, and the top of the mounting bracket 102 is fixedly equipped with an output shaft and a cylinder 202 fixedly equipped with the top of the lifting plate 201. The wiring assembly 3 includes a housing 301. The outer wall of the housing 301 is provided with a sealing plate 302. The outer wall of the sealing plate 302 is provided with screws 303. The inner wall of the housing 301 is fixedly mounted with an mounting plate 304. The top of the mounting plate 304 is provided with a sliding groove 307. The inner wall of the sliding groove 307 is slidably connected to a limiting seat 308. The top of the limiting seat 308 is fixedly mounted with a moving plate 305. The outer wall of the moving plate 305 is provided with a storage groove 306. The side wall of the moving plate 305 near the sealing plate 302 is fixedly mounted with a positioning plate 309. The outer wall of the positioning plate 309 is provided with an adjusting screw 310. The end of the adjusting screw 310 near the mounting plate 304 is rotatably connected to an arc plate 311. The bottom of the moving plate 305 is provided with an adjusting screw 312. The top of the adjusting screw 312 is rotatably connected to a pressing plate 313. The second wiring assembly 4 includes a protective shell 401 that is fixedly mounted to the top of the mounting bracket 102, and a wire rod 402 is also fixedly mounted to the top of the mounting bracket 102.

[0026] The advantage is that, through the structure of the frame assembly 1, detection assembly 2, wiring assembly 3, housing 301, sealing plate 302, screw 303, mounting plate 304, moving plate 305, storage slot 306, adjusting screw 310, and arc plate 311, the user can place the wire harness in the storage slot 306 during use, and then rotate the adjusting screw 310 to make the outer wall of the arc plate 311 fit tightly with the wire harness, thereby evenly fixing the wire harness in the housing 301. This makes it easier for the user to organize the wire harness, thus improving the practicality of the test fixture.

[0027] Specifically: the top of the extrusion plate 313 is tightly fitted to the bottom of the mounting plate 304, and the limiting seat 308 and the moving plate 305 are both fixedly connected to the mounting plate 304 through the extrusion plate 313.

[0028] The advantage is that, through the structure of the extrusion plate 313 and the mounting plate 304, the user can rotate the adjusting screw 312 to detach the extrusion plate 313 from the bottom of the mounting plate 304 during the use of the test fixture. This allows the user to adjust the spacing between several moving plates 305, making it easier to fix wire harnesses of different diameters. This increases the range of wire harness applications of the test fixture, makes it easier for the user to operate, and further improves the practicality of the test fixture.

[0029] Specifically: A wire harness is placed on the inner wall of the storage slot 306, and the wire harness is fixedly connected to the mounting plate 304 through the arc plate 311.

[0030] The advantage is that, through the structure of the mounting plate 304 and the arc plate 311, the user only needs to rotate the adjusting screw 310 to make the arc plate 311 move laterally during the use of the test fixture, which makes it easy for the user to clamp wire harnesses of different diameters, thereby ensuring the stability of the wire harness during the use of the test fixture.

[0031] Specifically: there are several movable plates 305, and all of them are evenly distributed along the outer wall of the mounting plate 304.

[0032] The advantage is that, through the structure of several movable plates 305, the test fixture can fix several wire harnesses through the housing 301 and the movable plates 305 during operation, thereby ensuring that there are not too many messy wire harnesses on the appearance of the test fixture, which makes it easier for users to operate the fixture and also optimizes the aesthetics of the test fixture.

[0033] Specifically: the outer wall of the guide rod 402 is tightly fitted to the outer wall of the wire harness, and the end of the wire harness near the cylinder 202 is fixedly connected to the mounting bracket 102 through the protective shell 401.

[0034] The advantage is that the wire harness is guided by the wire rod 402 structure, which makes it easier for the user to put the wire harness into the protective shell 401. The protective shell 401 provides protection for the wire harness, preventing the wire harness from being exposed to the outside environment for a long time, which would lead to increased wear of the insulation layer. This improves the protective effect of the test fixture on the wire harness.

[0035] Specifically, there are four housings 301, and all four housings 301 are evenly distributed along the top of the base 101.

[0036] The advantage is that, through the four housings 301 structure, the wiring harnesses used by the cylinder 202 on the test fixture and the circuit components inside the fixture can be routed through housings 301 at different positions, which makes it convenient for users to assemble the test fixture and further improves the practicality of the test fixture.

[0037] Specifically: The bottom of the movable plate 305 has a through hole, and the inner wall of the through hole is threadedly connected to the outer wall of the adjusting screw 312.

[0038] The advantage is that, through the through hole and adjusting screw 312, when the user rotates adjusting screw 312, the top of the pressing plate 313 will disengage from the bottom of the mounting plate 304, so that the end of the moving plate 305 away from the limiting seat 308 will not exert a pulling force on the limiting seat 308. This allows the limiting seat 308 to slide along the inner wall of the slide groove 307, making it easy for the user to adjust the spacing between several moving plates 305, thereby ensuring the normal use of the test fixture.

[0039] Working principle: First, when assembling the test fixture, the user can remove the sealing plate 302, then place the wire harness in the storage slot 306, and then rotate the adjusting screw 310 to make the arc plate 311 fit tightly against the outer wall of the wire harness, thereby fixing the wire harness. Then, the unfixed part of the wire harness is placed on the guide rod 402 and then inserted into the protective shell 401, thereby providing protection for the wire harness and improving the stability and protection of the wire harness during the operation of the test fixture. When installing the wire harness, the user can also rotate the adjusting screw 312 to make the limiting seat 308 slide along the inner wall of the slide groove 307, thereby adjusting the spacing between several moving plates 305, thus ensuring that the test fixture can be assembled with wire harnesses of different thicknesses, improving the practicality of the test fixture.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
