Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile detection, in particular to a detection tool for simulating the installation mode of a whole vehicle. Background Art
[0002] The combination switch of a car is a switch that is often used as a power source to control various electrical devices, such as lights, turn signals, wipers, etc. The combination switch is usually installed on the steering column of the car and consists of two or more switches to control the lights, signals, and control electrical appliances of the car. The combination switch has different gears and conversion forces to meet the different operating needs of the driver. In the car combination switch, it usually includes the light control switch, wiper and windshield wiper switch, hazard warning flasher switch, etc.
[0003] When enterprises produce hand-held switch handles, most of them are universal measuring tools or inspection tools for a single size, and they cannot have both the online inspection function and the function of the measuring bracket. At the same time, traditional measuring tools, such as smooth plug gauges, threaded plug gauges, outer diameter calipers, etc., are increasingly unable to meet the matching requirements of high-precision and complex curved surface shapes. In addition, when fixing the workpiece, it is fixed by sleeves on a fixed table. The positions of both ends of the workpiece are not fixed, so when the placement is completed, the workpiece cannot reach a stable placement state, resulting in the inability to align the fixings. When testing the combination switch, the error between the fixing and the fixing leads to differences in the test results. Incorrect fixing may cause the operator to misjudge the performance of the switch. For example, a switch with good performance may be mistaken for a fault due to incorrect fixing. This may lead to unnecessary replacement or repair, adding unnecessary costs and time. Utility Model Content
[0004] The purpose of the utility model is to provide a test fixture for simulating the installation mode of a whole vehicle, so as to solve the problems raised in the above-mentioned background technology.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A test fixture simulating the installation of a whole vehicle comprises a base, a fixing platform 1 is arranged above the base, a workpiece is placed on the top of the fixing platform 1, fixing platforms 2 are arranged on both sides of the workpiece, a clamp is arranged on the top of the fixing platform 2, stable clamping mechanisms are arranged at both ends of the workpiece, the stable clamping mechanism cooperates with a fixing component arranged at one end of the clamp to tighten the handles at both ends of the workpiece and then press it for detection, which can reduce the movement or vibration of the workpiece during the detection process, thereby ensuring the precision and accuracy of the detection.
[0007] Preferably, a fixing plug is provided on the side of the clamp that contacts the workpiece after being flipped, and a raised cylinder is provided on the top of the fixing table, which is used to sleeve the workpiece on its outer surface. The workpiece is initially fixed on the fixing table by the raised cylinder, which can ensure that the workpiece remains stable during subsequent inspection or operation and reduce the risk of movement or slipping.
[0008] Preferably, the second fixing platform is hinged to the clamp, and a third fixing platform is arranged above the base.
[0009] Preferably, a vertical clamp is provided at the top of the fixed platform 3, and detection pins are symmetrically provided on the vertical clamp.
[0010] Preferably, a positioning piece is provided on one side of the detection pin, a go / no-go gauge is provided above the base, and a signal transmission device is connected between the go / no-go gauge and the inspection fixture. By transmitting signals, the state of the go / no-go gauge and the reading of the inspection fixture can be detected in real time to ensure the accuracy of the detection.
[0011] Preferably, the stable clamping mechanism includes a bracket, the base is connected to the bracket and is located at the top of the base, and the bracket is used for support to ensure the stability of the connection between the mechanisms.
[0012] Preferably, the brackets on the top of the base are located on both sides of the workpiece, and scissor-type clamps are arranged above the brackets on the top of the base. The scissor-type clamps are synchronous. When the two scissor-type clamps move synchronously, their clamping force on the workpiece is evenly distributed, which avoids tilting or movement of the workpiece during the clamping process and improves the stability of the clamping.
[0013] Preferably, the bottom end of the scissor-type clamp slides in a groove formed in the bracket, and the groove provides a guide for the movement of the scissor-type clamp, ensuring that the clamp does not deviate from a preset path during movement and remains stable. Since the bottom end of the scissor-type clamp slides in the groove, the contact area between the scissor-type clamp and the groove is increased, reducing the risk of the clamp tilting during movement, and ensuring the stability and accuracy of clamping.
[0014] Preferably, a push-pull rod is provided below the connection of the scissor-type clamp, and the push-pull rod slides below the scissor-type clamp. The scissor-type clamp is adjusted to clamp both ends of workpieces of different sizes by sliding the push-pull rod, thereby ensuring stability during workpiece inspection.
[0015] Preferably, a cylinder is hinged below the push-pull rod, and the cylinder is connected to the base. The cylinder output shaft pushes the push-pull rod, so that the scissor-type bracket can stably clamp and fix workpieces of different sizes. Since the cylinder can push the push-pull rod, the scissor-type bracket can adapt to workpieces of different sizes. Regardless of the size of the workpiece, the scissor-type bracket can stably clamp and fix it by adjusting the position of the cylinder and the push-pull rod.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] The use of a stable clamping mechanism in conjunction with a fixing assembly allows the workpiece to be fixed and clamped more quickly, reducing the preparation time before testing and improving work efficiency. Stable clamping and fixing can prevent the workpiece from accidentally moving or popping out during testing, thereby reducing the risk of injury to the operator.
[0018] The cylinder is used in conjunction with the scissor-type clamp to adapt to workpieces of different sizes for clamping and fixing. By adjusting the clamping force and angle of the clamp, it can adapt to the thickness and shape changes of different workpieces to ensure that the workpiece is firmly fixed. At the same time, it can achieve fast clamping and release, quickly complete the clamping work, improve the clamping efficiency, accurately control the clamping force and clamping angle of the workpiece, and ensure the stability and precision requirements of the workpiece.

[0024] The utility model is described in further detail below in conjunction with the accompanying drawings.
[0025] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be used for other implementation schemes, variations, improvements, equivalent schemes, and other technical solutions that do not deviate from the spirit and scope of the utility model.
[0026] Those skilled in the art should understand that, in the disclosure of the present invention, the directions or positions indicated by the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, which are only simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.
[0027] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example
[0028] See also Figure 1-Figure 3 A test fixture simulating the installation of a whole vehicle comprises a base 1, a fixed platform 2 is arranged above the base 1, a workpiece 3 is placed on the top of the fixed platform 2, fixed platforms 4 are arranged on both sides of the workpiece 3, a clamp 5 is arranged on the top of the fixed platform 4, and stable clamping mechanisms are arranged at both ends of the workpiece 3. The stable clamping mechanism cooperates with a fixed component arranged at one end of the clamp 5, so that the handles at both ends of the workpiece 3 are tightened and then pressed for detection, which can reduce the movement or vibration of the workpiece 3 during the detection process, thereby ensuring the precision and accuracy of the detection.
[0029] It should be noted that the workpiece 3 may deform when subjected to pressure, especially when its two ends are not tightened. By tightening the handle first and then applying the clamping force, the deformation of the workpiece 3 can be effectively prevented, ensuring the reliability of the test results. The use of a stable clamping mechanism in conjunction with a fixing assembly can allow the workpiece 3 to be fixed and clamped more quickly, reducing the preparation time before testing and improving work efficiency. Stable clamping and fixing can prevent the workpiece 3 from accidentally moving or popping out during the test, thereby reducing the risk of injury that the operator may face.
[0030] Among them, after the clamp 5 is flipped, a fixing plug is provided on the side that fits with the workpiece 3, and a raised cylinder is provided on the top of the fixed table 2, which is used to sleeve the workpiece 3 on its outer surface. The workpiece 3 is initially fixed on the fixed table through the raised cylinder, which can ensure that the workpiece 3 remains stable during subsequent inspection or operation, reducing the risk of movement or slipping.
[0031] Among them, the fixing platform 2 4 is hinged with the clamp 5, and a fixing platform 3 6 is arranged above the base 1. A vertical clamp 7 is arranged at the top of the fixing platform 3 6, and a detection pin 8 is symmetrically arranged on the vertical clamp 7.
[0032] A positioning piece 9 is provided on one side of the detection pin 8, a go / no-go gauge 10 is provided above the base 1, and a signal transmission device is connected between the go / no-go gauge 10 and the inspection fixture. By transmitting signals, the state of the go / no-go gauge 10 and the reading of the inspection fixture can be detected in real time to ensure the accuracy of the detection.
[0033] The stable clamping mechanism includes a bracket, the base 1 is connected to the bracket and is located at the top of the base 1. The bracket is used for support to ensure the stability of the connection between the mechanisms.
[0034] The brackets on the top of the base 1 are located on both sides of the workpiece 3. Scissor-type clamps are arranged above the brackets on the top of the base 1. The scissor-type clamps are synchronous. When the two scissor-type clamps move synchronously, their clamping force on the workpiece 3 is evenly distributed, which avoids the workpiece 3 from tilting or moving during the clamping process and improves the stability of the clamping.
[0035] It should be noted that the bottom end of the scissor-type clamp slides in the groove opened by the bracket, and the groove provides a guide for the movement of the scissor-type clamp, ensuring that the clamp will not deviate from the preset path during movement and remain stable. Since the bottom end of the scissor-type clamp slides in the groove, the contact area between it and the groove is increased, reducing the risk of the clamp tilting during movement, and ensuring the stability and accuracy of clamping.
[0036] A push-pull rod is provided below the connection of the scissor-type clamp, and the push-pull rod slides below the scissor-type clamp. The scissor-type clamp is adjusted by sliding the push-pull rod to clamp the two ends of the workpiece 3 of different sizes, thereby ensuring the stability of the workpiece 3 during inspection.
[0037] A cylinder is hinged below the push-pull rod, and the cylinder is connected to the base 1. The cylinder output shaft pushes the push-pull rod, so that the scissor-type bracket can stably clamp and fix workpieces 3 of different sizes. Since the cylinder can push the push-pull rod, the scissor-type bracket can adapt to workpieces of different sizes 3. Regardless of the size of the workpiece 3, the scissor-type bracket can be stably clamped and fixed by adjusting the position of the cylinder and the push-pull rod.
[0038] Specifically, after the cylinder is started, the cylinder output shaft pushes the push-pull rod, causing the angle of the scissor-type bracket to continuously decrease, stably clamping the two ends of the workpiece 3 of different sizes, avoiding the shaking of the workpiece 3 after the initial fixation. Through the linkage of the cylinder and the push-pull rod, the scissor-type bracket can stably clamp the workpiece 3 of different sizes, avoiding the shaking of the workpiece 3 due to operation or its own reasons after the initial fixation. This greatly enhances the stability of the workpiece 3 during the entire detection process.
[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
[0040] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments.
