Description

Technical Field

[0001] This utility model belongs to the field of automotive center console panel testing technology, and more specifically, it relates to a panel surface heat resistance testing device. Background Technology

[0002] Automotive center consoles are typically made of various polymer materials, and their heat resistance is one of the important quality indicators. The heat distortion Vicat softening point temperature tester can effectively evaluate the performance changes of these materials under high temperature environments. Existing heat distortion Vicat softening point temperature testers generally consist of a main body of the instrument, a heating system, a load application system, a sample placement stage, a per mille display, and a control system.

[0003] Existing application number: CN202320988014.3, this utility model relates to the field of measuring instrument technology, and discloses a heat distortion Vicat softening point temperature measuring instrument. The instrument includes a storage device that allows for the placement of weights of different sizes according to their corresponding storage slots. The weights are placed on top of the storage slots and pressed down, causing the weight compression block to retract until the weight is locked into the storage slot. To remove the weights, simply push the pusher forward to move the push rod forward, pushing the weight from the storage slot into the slot body for direct retrieval. This is very convenient, as the instrument is located on top of the Vicat softening point temperature measuring instrument, eliminating the need to bend over, saving time, and protecting the operator's body. The instrument also features text boxes that allow users to clearly indicate the mass of different weight specifications according to their corresponding storage slots, making the instrument easier to use.

[0004] Based on the above, when testing automotive center console panel samples, after placing the sample on the test bench, the probe of the dial indicator needs to be retracted by 4-6 mm to ensure stable contact between the probe and the sample surface, so that the data accurately reflects the actual displacement of the measured part. The existing adjustment method requires first loosening the limiting bolt of the dial indicator, manually adjusting the probe to the target position, and then tightening the bolt to fix it. This operation needs to be repeated when disassembling after testing. This process is not only cumbersome, time-consuming, and labor-intensive, but also prone to deviations in manually controlling the bolt tightening force. If the force is insufficient, the dial indicator may shift up and down due to vibration or force changes during the testing process, resulting in distorted deformation measurement data and affecting the accuracy and reliability of the test results. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a device for testing the heat resistance of a panel surface. This solves the problem that existing methods for testing automotive center console panel samples require retracting the dial indicator probe by 4-6 mm after placing the sample on the test bench to ensure stable contact between the probe and the sample surface, thus accurately reflecting the actual displacement of the tested component. The existing adjustment method requires first loosening the limiting bolts securing the dial indicator, manually adjusting the probe to the target position, and then tightening the bolts again. This process must be repeated upon disassembly after testing. This is not only cumbersome and time-consuming, but also prone to errors due to manual control of bolt tightening force. Insufficient force can cause the dial indicator to shift vertically during testing due to vibration or force changes, leading to distorted deformation measurement data and affecting the accuracy and reliability of the test results.

[0006] The purpose and effectiveness of this utility model, a device for testing the heat resistance of a panel surface, are achieved through the following specific technical means:

[0007] A panel surface heat resistance testing device includes a testing instrument body, a support plate, fixed columns, sliders, insertion columns, digital displays, quick adjustment components, and separation and maintenance components. The support plate is disposed inside the testing instrument body. Three fixed columns are provided, which are distributed and fixedly connected to the support plate. Three sliders are provided, which are slidably connected to the three fixed columns. Three insertion columns are provided, which are inserted into the front ends of the three sliders. Three digital displays are provided, which are fixedly connected to the front ends of the three insertion columns. Three sets of quick adjustment components are provided, which are disposed inside the three fixed columns. Three sets of separation and maintenance components are provided, which are disposed above the three insertion columns.

[0008] Furthermore, the quick adjustment assembly includes: a transmission rack, a first transmission shaft, and a transmission gear; the transmission rack is fixedly connected to the slider; the first transmission shaft is rotatably connected to the top of the fixed column; the transmission gear is coaxially fixedly connected to the outside of the first transmission shaft, and the transmission gear meshes with the transmission rack.

[0009] Furthermore, the quick adjustment assembly also includes: a limiting ratchet and a limiting pawl; the limiting ratchet is coaxially fixedly connected to the right end of the first drive shaft; the limiting pawl is rotatably connected to the top of the fixed column, and the limiting pawl engages with the limiting ratchet.

[0010] Furthermore, the quick adjustment assembly also includes: a limiting spring and a spiral spring; the lower end of the limiting spring is fixedly connected to the front end of the limiting pawl, and the upper end of the limiting spring is fixedly connected to the inside of the fixed column; the inner end of the spiral spring is fixedly connected to the outside of the first drive shaft, and the outer end of the spiral spring is fixedly connected to the inside of the fixed column.

[0011] Furthermore, the separation and maintenance assembly includes: a fixed box, a sliding plate, and a moving column; the fixed box is fixedly connected to the slider; the sliding plate is slidably connected inside the fixed box; and the moving column is fixedly connected to the sliding plate.

[0012] Furthermore, the separation and maintenance assembly also includes: a positioning post, a reset spring, and a positioning groove; the positioning post is fixedly connected to the bottom of the sliding plate; the bottom of the reset spring is fixedly connected to the top of the sliding plate, and the top of the reset spring is fixedly connected to the inside of the fixing box; the positioning groove is formed inside the insertion post.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, by quickly adjusting the component settings, the position of the digital display can be quickly adjusted without the need for traditional bolt tightening operations. This allows the probe of the digital display to be quickly retracted by 4-6 mm and stably fixed, making operation and positioning faster and more accurate, and ensuring the rapid replacement and testing of multiple sets of test samples.

[0015] Secondly, by separating the positioning column and positioning groove of the maintenance component, the positioning column can be disengaged from the positioning groove by pulling the moving column upward, realizing tool-free quick disassembly of the digital display. After maintenance, the plug-in column is inserted, and when the moving column is released, the reset spring drives the positioning column to automatically snap into the positioning groove, completing precise fixation. This solves the problems of cumbersome operation and unstable positioning of traditional bolt fastening methods, and greatly improves the maintenance efficiency and installation accuracy of digital display.

[0016] This invention uses a quick-adjustment component to quickly adjust the digital display to the required position, solving the problems of tedious manual adjustment and positioning deviation. The separate inspection component significantly improves inspection efficiency and installation accuracy when inspecting the digital display. Overall, it is suitable for batch testing scenarios of automotive center console panels and can effectively reduce the distortion of test data caused by equipment adjustment errors.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a device for testing the heat resistance performance of a panel surface, including a tester body 1, a support plate 2, fixed columns 3, sliders 4, insertion columns 5, digital displays 501, and quick adjustment components; the support plate 2 is disposed inside the tester body 1; three fixed columns 3 are disposed and fixedly connected to the support plate 2; three sliders 4 are disposed and slidably connected to the three fixed columns 3; three insertion columns 5 are disposed and inserted into the front end of the three sliders 4; three digital displays 501 are disposed and fixedly connected to the front end of the three insertion columns 5; three sets of quick adjustment components are disposed inside the three fixed columns 3.

[0029] The quick adjustment assembly also includes a limiting ratchet 702 and a limiting pawl 8; the limiting ratchet 702 is coaxially fixedly connected to the right end of the first drive shaft 7; the limiting pawl 8 is rotatably connected to the top of the fixed column 3, and the limiting pawl 8 engages with the limiting ratchet 702.

[0030] The quick adjustment assembly also includes: a limit spring 801 and a spiral spring 703; the lower end of the limit spring 801 is fixedly connected to the front end of the limit pawl 8, and the upper end of the limit spring 801 is fixedly connected to the inside of the fixed column 3; the inner end of the spiral spring 703 is fixedly connected to the outside of the first drive shaft 7, and the outer end of the spiral spring 703 is fixedly connected to the inside of the fixed column 3.

[0031] The specific usage and function of this embodiment are as follows: In use, firstly, move the slider 4 to the top. Under the action of the gear and rack transmission mechanism formed by the meshing of the transmission gear 701 and the transmission rack 6, the first transmission shaft 7 rotates, and simultaneously the spiral spring 703 tightens. Then, place the weights for the load on the weight tray of the bearing plate 2. Next, hold the slider 4 by hand and push the front end of the limiting pawl 8 upwards, causing the limiting pawl 8 to disengage from the limiting ratchet 702.
