Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a device for inspecting the gate position of a control arm blank. Background Technology
[0002] In automotive manufacturing, the control arm is a critical component of the vehicle's suspension system, and its quality directly affects the vehicle's handling stability and driving safety. Control arm blanks are typically produced using casting processes. The gate, as the channel through which molten metal flows into the mold cavity, has a decisive impact on the forming quality, internal structure uniformity, and subsequent machining accuracy of the control arm blank. Improper gate placement can easily lead to insufficient molten metal filling, defects such as porosity and shrinkage, and consequently affect the mechanical properties and service life of the control arm.
[0003] Currently, the inspection of the gate position of the control arm blank mostly relies on manual visual inspection or simple caliper measurement. Manual visual inspection is greatly affected by the inspector's subjective experience and visual fatigue, making it difficult to accurately judge the gate position deviation and resulting in a high risk of missed or false detections. Caliper measurement can only obtain single-point or local dimensional data of the gate position, and cannot fully reflect the spatial coordinate information and overall deviation of the gate position, leading to inaccurate inspection data and large errors. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned technology and provide a device for inspecting the position of the gate of the control arm blank.
[0005] Therefore, this utility model provides a control arm blank gate position inspection device, including a base, on which a plurality of positioning rods for positioning the control arm body are fixedly installed, and a column is fixedly installed on the base on one side of the control arm body. A rotating plate is rotatably installed on the column, and a detection pin for detecting the gate position on the control arm body is installed on the rotating plate.
[0006] Preferably, the detection pin is connected to the rotating plate via an elastic component, the elastic component being used to reset the detection pin.
[0007] Preferably, the elastic component includes a spring and a mounting sleeve. The outer ring of the mounting sleeve is fixedly installed in the through hole of the rotating plate. An annular plate is fixedly installed on the detection pin. The detection pin below the annular plate is inserted into the mounting sleeve. One end of the spring is fixedly connected to the bottom of the inner ring of the mounting sleeve, and the other end is fixedly connected to the annular plate.
[0008] Preferably, the diameter of the annular plate is smaller than the diameter of the top of the mounting sleeve, but larger than the diameter of the bottom of the mounting sleeve.
[0009] Preferably, the top of the rotating plate is provided with a step, and the left and right sides of the detection pin are located at the high and low points of the step, respectively.
[0010] Preferably, the column is provided with a horizontal stop bar, and a vertical bar is fixedly installed at the bottom of the rotating plate. The stop bar is used to limit the rotation position of the vertical bar.
[0011] Preferably, a handle is installed at the end of the rotating plate away from the column.
[0012] The beneficial effects of this utility model are as follows: This utility model provides a control arm blank gate position inspection device, which has the following beneficial effects.
[0013] When it is necessary to inspect the gate position of the control arm blank, first place the control arm blank on the corresponding positioning rod, then pull the handle to rotate the rotating plate so that the detection pin on the rotating plate corresponds to the position of the gate. The worker manually presses down the detection pin so that the detection pin is inserted into the corresponding gate. If the top height of the detection pin is level with the height of the step, it means that the gate height is qualified; if it is not level, it means that the gate height of the control arm blank is unqualified. This allows for quick inspection of the relative position and height of multiple gates on the control arm blank. The inspection method is simple and easy to operate, greatly improving the efficiency of inspection. It eliminates the need for manual measurement by workers, reducing their workload, and the inspection results are more accurate.
[0014] When the test pin is pressed down and inserted into the gate, the spring is compressed. After the inspection is completed, the spring quickly returns to its original position, which in turn drives the test pin to return to its original position. Then, by rotating the turntable, the control arm can be removed and replaced with the next control arm to be inspected. The operation process is smooth and does not require manual time and effort to remove the test pin, resulting in high work efficiency.
[0015] The stop lever can limit the rotation direction of the turntable and prevent the turntable from rotating too much and interfering with the adjacent equipment. Attached Figure Description

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0024] Example:
[0025] like Figures 1-6 As shown, this utility model provides a control arm blank gate position inspection device, including a base 1. Multiple positioning rods 3 for positioning the control arm body 2 are fixedly installed on the base 1 by bolts or the like. Each positioning rod 3 includes a first positioning rod 31 and a second positioning rod 32. In this embodiment, there are two first positioning rods 31. The top of the first positioning rod 31 is spherical, which matches the concave spherical hole 21 at the bottom of the control arm body 2, resulting in good positioning. The top of the second positioning rod 32 is a cylindrical plane, which matches the bottom plane of the control arm body 2. The two first positioning rods 31 and one second positioning rod 32 are distributed in a triangular shape on the base 1 to ensure the stability of the support.
[0026] A column 4 is fixedly installed on the base 1 on one side of the control arm body 2. A rotating plate 5 is rotatably installed on the top of the column 4. A detection pin 6 for detecting the position of the gate on the control arm body 2 is installed on the rotating plate 5. The number and position of the detection pin 6 match the number and position of the gate. Since there are two gates in this embodiment, there are also two detection pins 6.
[0027] Furthermore, the detection pin 6 is connected to the rotating plate 5 via an elastic component 7, which is used to reset the detection pin 6.
[0028] Furthermore, the elastic component 7 includes a spring 71 and a mounting sleeve 72. The outer ring of the mounting sleeve 72 is fixedly installed in the vertical through hole of the rotating plate 5. An annular plate 8 is fixedly installed on the detection pin 6. The detection pin 6 below the annular plate 8 is inserted into the mounting sleeve 72. The upper part of the detection pin 6 is located in the vertical through hole of the rotating plate 5. One end of the spring 71 is fixedly connected to the bottom of the inner ring of the mounting sleeve 72, and the other end is fixedly connected to the bottom of the annular plate 8.
[0029] Furthermore, the diameter of the annular plate 8 is smaller than the diameter of the top of the mounting sleeve 72, allowing the annular plate 8 to move up and down within the mounting sleeve 72 for inspection; an annular inner plate is integrally provided on the bottom inner side of the mounting sleeve 72, making the diameter of the annular plate 8 larger than the diameter of the bottom annular inner plate of the mounting sleeve 72, to prevent the annular plate 8 from moving downwards beyond the bottom of the mounting sleeve 72 when the detection pin 6 is pressed down, causing the spring 71 to twist and affecting the normal reset of the spring 71.
[0030] Furthermore, the top of the rotating plate 5 is provided with a step 9, and the left and right sides of the detection pin 6 are located at the high and low points of the step 9, respectively.
[0031] The step 9 allows for direct observation of whether the gate height meets manufacturing requirements. If the top of the inspection pin 6 is level with the high point of step 9, the gate meets the requirements; if the top of the inspection pin 6 is lower than the high point of step 9, reaching the low point of step 9, the gate height is too deep and does not meet the requirements; if the top of the inspection pin 6 is higher than the high point of step 9, the gate height is too shallow and also does not meet the requirements.
[0032] Furthermore, a horizontal stop bar 10 is provided on the column 4, and a vertical rod 11 is fixedly installed at the bottom of the rotating plate 5. The stop bar 10 is used to limit the rotation position of the vertical rod 11 to prevent the rotating plate 5 from rotating too much and interfering with the adjacent equipment.
[0033] When the vertical rod 11 on the rotating plate 5 is blocked by the stop rod 10, the control arm body 2 on the positioning rod 3 can be removed and replaced with the next control arm body 2 to be inspected.
[0034] Furthermore, a handle 12 is installed at the end of the rotating plate 5 away from the column 4 to facilitate rapid rotation of the rotating plate 5.
[0035] Furthermore, handles 13 are installed on the front and rear sides of the base 1 in a staggered manner to facilitate quick movement of the device.
[0036] Furthermore, a limiting plate 14 is fixedly installed on the side of the positioning rod 31 located on the left side of the base 1. The limiting plate 14 can not only be used to quickly identify the installation direction of the control arm body 2, but also to initially limit the position of the control arm body 2.
[0037] The working principle is as follows:
[0038] When it is necessary to inspect the gate position of the control arm body 2, first place the control arm body 2 on the corresponding positioning rod 3, then pull the handle 12 and rotate the rotating plate 5 so that the detection pin 6 on the rotating plate 5 corresponds to the position of the gate. The worker manually presses down the detection pin 6 so that the detection pin 6 is inserted into the corresponding gate. Since the gate is usually closed at the bottom after casting, the insertion of the detection pin 6 can detect the height of the gate.
[0039] If the top of the test pin 6 is level with the high point of the step 9, the gate meets the requirements; if the top of the test pin 6 is lower than the high point of the step 9 and reaches the low point of the step 9, the gate height is too deep and does not meet the requirements; if the top of the test pin 6 is higher than the high point of the step 9, the gate height is too shallow and also does not meet the requirements.
