Description

Technical Field

[0001] This utility model relates to the field of plastic parts testing technology, and in particular to a testing device for plastic parts used in the cover of a boss key. Background Technology

[0002] The "boss button" in a car is a button next to the front passenger seat for adjusting the seat. It is designed to improve the comfort and ease of operation for rear passengers. The cover is used to protect the boss button and cover the mounting holes and fixing structure of the boss button switch on the side panel of the seat, thereby enhancing the aesthetics of the car interior.

[0003] The cover of the main button typically has a complex curved shape and a precise mounting structure, requiring extremely high precision in dimensional contours and hole alignment. Currently, quality inspection of the cover in existing production mainly relies on manual labor. Operators visually inspect the product and compare it with standard samples to determine whether there are appearance defects such as deformation or hole misalignment. This inspection method is highly dependent on personal experience and subjective judgment, which is not only inefficient but also prone to misjudgment due to visual fatigue. As a result, some defective products with slight dimensional deviations enter the subsequent final assembly stage, causing assembly difficulties, abnormal noises, or uneven gaps, seriously affecting the overall vehicle quality.

[0004] Therefore, in order to solve the problems of insufficient accuracy, poor stability and low efficiency of the existing manual inspection methods, it is urgent to develop a special inspection device for the boss key cover to achieve rapid, objective and accurate identification of its shape and key dimensions. Summary of the Invention

[0005] The purpose of this invention is to provide a detection device for plastic parts used in the cover of a boss key, which has a simple structure, is highly practical, and can improve detection accuracy and efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A testing device for plastic parts used in the cover of a boss key includes a base; the base is provided with a product positioning seat, a clamp, a position measurement gauge, and a go / no-go gauge; the position measurement gauge includes a positioning pin, a positioning pin base, and a pin; the positioning pin is slidably disposed within the positioning pin base; the positioning pin and the positioning pin base are respectively provided with positioning holes; the pin passes through the positioning hole of the positioning pin and is inserted into the positioning hole of the positioning pin base; the clamp is located outside the product positioning seat; a gap is provided between the clamp and the product positioning seat; the positioning pin base is located outside the clamp.

[0007] In this utility model, the product positioning seat is used to position the product. Depending on the design of the product to be tested, it can be an integral structure or a split structure. The upper surface is provided with a boss key control button, which is conventional technology and does not affect the understanding of this utility model by those skilled in the art. The boss key cover is provided with a control button through hole. In actual application, the boss key cover is placed on the product positioning seat. There is a gap between the control button through hole of the boss key cover and the control button of the product positioning seat. There is also a gap between the product positioning seat and the fixture. All of these gaps are used to insert go / no-go gauges to check whether the product's outline is qualified. The size of the gap between the control button through hole of the boss key cover and the control button of the product positioning seat, and the gap between the product positioning seat and the fixture, are designed according to the shape precision requirements of the product to be tested.

[0008] In this utility model, the position measurement tool is used to check whether the snap-fit ​​position of the boss key cover is qualified. The positioning pin has two ends, one end is the test end and the other end is the moving end. The test end is the end of the positioning pin that contacts the product, and the moving end is the end held by the operator. In actual application, the positioning pin is first pushed to the non-working state (the operator holds the moving end of the positioning pin and pushes it to the bottom towards the test end). Then, the product is placed on the product positioning seat, the moving end of the positioning pin is pulled, and the pin is inserted into the positioning pin base. It is observed whether the end of the positioning pin can contact the snap-fit. If the end of the positioning pin contacts the snap-fit, it means that the snap-fit ​​position of the boss key cover is qualified; otherwise, it is a defective product.

[0009] Furthermore, the product positioning seat is mounted on the base via a product positioning seat base. The product positioning seat base is used to mount the product positioning seat.

[0010] Furthermore, the clamp is mounted on the base via a clamp base. More preferably, the clamp is detachably mounted on the clamp base; the base is provided with a clamp storage rack. The clamp base is used to mount the clamp, and the clamp storage rack is used to store the clamp.

[0011] Furthermore, the go / no-go gauge includes a go gauge, a no-go gauge, and a connector; the two ends of the connector are respectively connected to the go gauge and the no-go gauge. The go / no-go gauge is used to check whether the product's external contour is within acceptable limits.

[0012] Preferably, the upper surface of the base is provided with a go / no-go gauge holder; the upper surface of the base is provided with a pin holder. The go / no-go gauge holder is used to store the go / no-go gauge, and the pin holder is used to store the pin.

[0013] Preferably, the clamp is further provided with a product fixing head on its outer side; the product fixing head is mounted on the base via a product fixing head base. The product fixing head is used to press down on the product to prevent the product from shifting or tilting during the inspection process, which would lead to inaccurate shape precision inspection.

[0014] Preferably, the base has a handle on its upper surface and support legs on its lower surface. The handle facilitates the movement of the device by operators.

[0015] Due to the application of the above technical solution, the beneficial effects of this utility model compared to the prior art are as follows: Through the coordinated operation of the product positioning seat, fixture, position gauge, and go / no-go gauge, rapid and accurate detection of the shape precision of the plastic part of the boss key cover is achieved. In practical application, utilizing the standardized gaps reserved between the product positioning seat and the fixture, and between the through hole of the cover control button and the control button of the product positioning seat, only the go / no-go gauge needs to be inserted into the gap to quantitatively judge the shape contour, effectively overcoming the drawbacks of low efficiency and large subjective error of traditional manual visual inspection. Furthermore, the position gauge, through the coordinated action of the positioning pin and the latch, can intuitively and reliably inspect the positional accuracy of the buckle, ensuring the assembly reliability of the buckle structure. This device has a compact structure and is simple to operate. Applied to the production line, it significantly improves inspection efficiency and provides a reliable guarantee for the stable control of product quality. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. The specific components involved are existing products, and the connection and usage methods between the specific components are conventional technologies. Example 1

[0028] like Figures 1 to 8 As shown: A testing device for plastic parts used in the cover of a boss key includes a base 1; the base is provided with a product positioning seat 2, a clamp 3, a position measurement gauge 4, and a go / no-go gauge 5; the position measurement gauge includes a positioning pin 401, a positioning pin base 402, and a pin 403; the positioning pin is slidably disposed in the positioning pin base; the positioning pin and the positioning pin base are respectively provided with positioning holes 40101; the pin passes through the positioning hole of the positioning pin and is inserted into the positioning hole of the positioning pin base; the clamp is located outside the product positioning seat; a first gap 6 is provided between the clamp and the product positioning seat; the positioning pin base is located outside the clamp.

[0029] In this embodiment, the product positioning seat is a split structure, see [link / reference]. Figure 3 This fixture is used for product positioning. Its specific shape is designed according to the product to be tested. The upper surface has a "boss key" control button, which is conventional technology and does not affect the understanding of this utility model by those skilled in the art. The boss key cover has a control button through-hole. In actual application, the boss key cover is placed on the product positioning seat, and there is a second gap 7 between the control button through-hole of the boss key cover and the control button of the product positioning seat. The size of the second gap between the control button through-hole of the boss key cover and the control button of the product positioning seat, and the first gap between the product positioning seat and the fixture, are designed according to the shape and precision requirements of the product to be tested.

[0030] The product positioning seat is mounted on the base via the product positioning seat base 8; the clamp is mounted on the base via the clamp base 9. In this embodiment, the clamp is detachably mounted on the clamp base via bolts 10; the clamp base also has a reference post 901, and the clamp has a through hole 301 that matches the reference post. In actual application, the through hole of the clamp is first aligned with the reference post for preliminary positioning and installation of the clamp, and then the bolts are screwed into the clamp base to complete the fixing of the clamp. In this embodiment, the base is provided with a clamp storage rack 11 for storing the clamp. The clamp is installed on the clamp storage rack in the same way as it is installed on the clamp base, and is detachably mounted on the clamp storage rack via bolts.

[0031] The go / no-go gauge includes a go gauge 501, a no-go gauge 502, and a connector 503; the two ends of the connector are respectively connected to the go gauge and the no-go gauge.

[0032] In this embodiment, the upper surface of the base is provided with a go / no-go gauge holder 12 and a pin holder 13, which are used to store the corresponding go / no-go gauges and pins, respectively.

[0033] In this embodiment, a product fixing head 14 is also provided on the outside of the clamp, which is mounted on the base via a product fixing head base 15. The product fixing head used is a conventional quick clamp.

[0034] In this embodiment, the upper surface of the base is provided with a handle 16, and the lower surface is provided with a support leg 17. Example 2

[0035] Based on Example 1, the difference in this example is that the product fixing head and the product fixing head base are omitted, while the rest are the same. Example 3

[0036] Based on Embodiment 1, the difference in this embodiment is that the handle and support legs are omitted, while the rest are the same.

[0037] Application Examples

[0038] The method for detecting the precision of the plastic part of the boss key cover using the apparatus of Example 1 is as follows: (1) Push all the positioning pins to the non-working state (push the moving end of the hand positioning pin towards the test end to the bottom), then install and fix the fixture on the fixture base, place the boss key cover 18 on the product positioning seat, and use quick clamps to press the product. (2) Pull the moving end of the positioning pin to insert the pin into the positioning pin base. If the end of the positioning pin contacts the buckle 1801 of the boss key cover, see Figure 9 If the result is satisfactory, proceed to the next step of testing; otherwise, the product is considered substandard. (3) Observe whether the four positioning pins 1802 at the four corners of the boss key cover are in contact with the upper surface of the product positioning seat. If all four positioning pins are in contact with the upper surface of the product positioning seat, see Figure 10 If the result is satisfactory, proceed to the next step of testing; otherwise, the product is considered substandard. (4) Take the go gauge for testing the first gap, put the go gauge end into the first gap and rotate it one turn. If the go gauge end is not stuck, and the no-go gauge end cannot be put into the first gap, then proceed to the next step of testing. If both the go gauge end and the no-go gauge end can be put into the first gap or neither can be put into the first gap, then the product is unqualified. (5) Take the go and no-go gauges for testing the second gap, put the go gauge end into the second gap and rotate it one turn. If the go gauge end does not get stuck and the no-go gauge end cannot be put into the second gap, the product is qualified and the product test is completed; otherwise, if both the go gauge end and the no-go gauge end can be put into the second gap or neither can be put into the gap, the product is unqualified.

[0039] This invention achieves rapid and accurate inspection of the shape precision of the plastic part of the boss key cover by coordinating the product positioning seat, fixture, position measurement gauge, and go / no-go gauge. In practical application, utilizing the standardized gaps reserved between the product positioning seat and fixture, and between the through hole of the cover control button and the control button of the product positioning seat, the go / no-go gauge only needs to be inserted into the gap to quantitatively judge the shape contour, effectively overcoming the drawbacks of low efficiency and large subjective error of traditional manual visual inspection. In addition, the position measurement gauge, through the coordinated action of the positioning pin and the latch, can intuitively and reliably inspect the positional accuracy of the buckle, ensuring the assembly reliability of the buckle structure. This device has a compact structure and is simple to operate. When applied to the production line, it significantly improves inspection efficiency and provides a reliable guarantee for the stable control of product quality.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered to fall within the protection scope of the present utility model.
