Description

Technical Field

[0001] This utility model relates to the technical field of equipment for manufacturing coated samples, specifically a pressure-type abrasion resistance testing component for coated samples. Background Technology

[0002] In existing technologies, after the coated sample is manufactured, it needs to undergo a friction resistance test. Specifically, a friction head is used to repeatedly rub the coated sample to observe whether the coated sample can achieve the required performance.

[0003] There are many existing testing devices for coated samples, and their mechanisms and working principles are roughly the same. For example, the patent document with authorization announcement number CN221445739U discloses "A friction resistance testing device for coated samples". This technical solution includes a base, a working plate, a driving device, a guide rail, a height adjustment device, a support seat, a working rod, and a friction head. The friction head is connected to a friction medium. The height adjustment device includes a bracket set on the base, a linear push rod set on the bracket, and a slider seat connected to the linear push rod. The support seat is connected to the slider seat through a first crossbar.

[0004] This technical solution uses a linear push rod connected to a slider seat to adjust the friction head to a fixed height, reducing testing errors caused by different friction head heights. The fixture and pressure plate device can fix both ordinary samples with a certain thickness and sheet-like samples, making the device widely applicable. The U-shaped first pressure plate in the pressure plate device has a wide pressing range and provides good fixation for sheet-like samples.

[0005] The above technical solution involves repeatedly rubbing the coated sample with a friction head for testing. However, this technical solution also has certain drawbacks in practical use.

[0006] When the reciprocating movement of the coated sample is large, the pressure on the working rod also increases. In the existing technology, the working rod is fixed only by the upper support. When the reciprocating movement of the coated sample is large, it will cause the working rod to tilt slightly in the left and right directions. Then the position of the friction head at the lower end of the working rod will shift, and the force on the friction sample will be uneven, which will seriously affect the friction test results of the coated sample.

[0007] Therefore, in order to solve the above problems, it is necessary to develop a pressure-bonded abrasion resistance testing component for coated samples with a reasonable structure that can correct test results. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing a pressure-bonded abrasion resistance testing component for coated samples; the technical solution is as follows:

[0009] A pressure-type abrasion resistance testing assembly for coated samples includes a support base movably connected to a height adjustment device. A support rod is provided at the upper end of the support base, and a working rod is provided at the lower end of the support rod. A friction head is provided at the lower end of the working rod. During operation, the friction head presses on the coated sample, and the coated sample moves back and forth. The friction head is used to perform abrasion resistance testing on the coated sample.

[0010] The working rod is also provided with an external thread on its outer diameter, and a corresponding threaded sleeve is fitted on the external thread. The working rod is also fitted with a lifting sleeve, which is placed on the threaded sleeve. By turning the threaded sleeve, the lifting sleeve is moved up and down on the working rod accordingly.

[0011] Furthermore, a spring rod is installed between the lifting sleeve and the support base. After the spring rod supports downwards, it presses down on the lower lifting sleeve. The height position of the lifting sleeve is adjusted by the threaded sleeve, so that the spring rod presses and fixes the working rod through the cooperation of the lifting sleeve.

[0012] Furthermore, the spring rod between the lifting sleeve and the support base is set at an angle; the angled spring rod has a good clamping force and can provide inward and downward forces, which is a reasonable structure.

[0013] Furthermore, corresponding hinge seats are provided at the upper edge of the lifting sleeve and the lower edge of the support seat. The upper and lower ends of the spring rod are respectively installed on the upper and lower hinge seats, so that the spring rod is set at an angle. When the lifting sleeve moves up and down, the position of the spring rod is adjusted accordingly by the hinge seats.

[0014] Furthermore, four sets of spring rods are arranged diagonally; the reasonable arrangement of the number and position of the spring rods effectively increases the pressure of the spring rods.

[0015] Furthermore, the spring rod includes a spring sleeve and a spring rod installed inside the spring sleeve, and a corresponding spring component is installed inside the spring sleeve.

[0016] Furthermore, the spring rod between the lifting sleeve and the support base is vertically arranged; the vertically arranged spring rod is easy to install and has a reasonable structure.

[0017] Furthermore, the support rod is provided with removable weights.

[0018] Beneficial effects: This utility model has the following beneficial effects:

[0019] 1) In this device, a lifting sleeve is set on the working rod, and a spring rod is set between the lifting sleeve and the support base. The working rod is pressed and fixed by the spring rod, so that the position of the working rod is fixed and there will be no positional displacement during the test, which effectively improves the test accuracy and precision.

[0020] 2) The spring rod in this device can be installed vertically or at an angle, which is operable. The angled installation can further increase the stability of the working rod, and the structure is reasonably designed.

[0021] 3) This device also has an external thread and a threaded sleeve installed on the working rod. The upper and lower positions of the lifting sleeve can be adjusted by setting the threaded sleeve, thereby adjusting the spring pressure of the spring rod, making the overall structure more stable and reliable.

[0022] 4) The device also includes a spring rod structure, including a spring sleeve, a spring rod body, and a spring component. The position and number of spring rods are determined by the reasonable setting of their position and number, which effectively increases the clamping force of the spring rods and makes the overall structure more reasonable.

[0028] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0029] like Figure 1 and Figure 2As shown, a pressure-type abrasion resistance test assembly for coated samples includes a support base 1, which is movably connected to a height adjustment device. A support rod 2 is provided at the upper end of the support base 1, and a working rod 3 is provided at the lower end of the support rod 2. A friction head 4 is provided at the lower end of the working rod 3. During operation, the friction head 4 presses on the coated sample 5, and the coated sample 5 moves back and forth from left to right. The friction head 4 is used to perform abrasion resistance test on the coated sample 5.

[0030] The working rod 3 is also provided with an external thread 6 on its outer diameter. A corresponding threaded sleeve 7 is fitted on the external thread 6. The working rod 3 is also fitted with a lifting sleeve 8. The lifting sleeve 8 is placed on the threaded sleeve 7. By turning the threaded sleeve 7, the lifting sleeve 8 is moved up and down on the working rod 3.

[0031] Furthermore, a spring rod 9 is installed between the lifting sleeve 8 and the support base 1. After the spring rod 9 supports downwards, it presses down on the lower lifting sleeve 8. The height position of the lifting sleeve 8 is adjusted by the threaded sleeve 7, so that the spring rod 9 presses and fixes the working rod 3 through the cooperation of the lifting sleeve 8.

[0032] The spring rod 9 between the lifting sleeve 8 and the support base 1 is set at an angle; a corresponding hinge seat 10 is provided at the upper edge of the lifting sleeve 8 and the lower edge of the support base 1. The upper and lower ends of the spring rod 9 are respectively installed on the upper and lower hinge seats 10, so that the spring rod 9 is set at an angle. When the lifting sleeve 8 moves up and down, the position of the spring rod 9 is adjusted accordingly by the hinge seat 10. There are four sets of spring rods 9 set at an angle.

[0033] like Figure 3 As shown, the spring rod 9 includes a spring sleeve 91 and a spring rod 92 installed inside the spring sleeve 91, and a corresponding spring element 93 is installed inside the spring sleeve 91.

[0034] like Figure 4 As shown, the spring rod 9 between the lifting sleeve 8 and the support base 1 is vertically arranged; a removable weight 11 is placed on the support rod 2.

[0035] The specific working principle of this device is as follows: The device first sets an external thread on the working rod, and then fits a threaded sleeve on the external thread. The threaded sleeve can move up and down. At the same time, a lifting sleeve is fitted on the working rod, and the lifting sleeve is positioned above the threaded sleeve. Thus, the lifting sleeve can adjust its position up and down under the action of the threaded sleeve, thereby adjusting the elastic force of the spring rod.

[0036] A spring rod is installed between the threaded sleeve and the support base. There are two installation methods for the spring rod in this device, one of which is as follows: Figure 4As shown, it can be installed vertically, with the spring rod pressing down directly against the lifting sleeve. The lifting sleeve, in turn, presses against the working rod through the threaded sleeve, making the overall structure of the working rod more stable and reliable.

[0037] Another installation method is angled installation, such as... Figure 1 As shown, this device has hinge seats on both the support base and the lifting sleeve. The spring rod is installed on the corresponding upper and lower hinge seats. When the position of the lifting sleeve is adjusted by the threaded sleeve, the position of the spring rod will change. The hinge seats can adapt to the change in the position of the spring rod. The pressure generated by the inclined spring rod is inclined downward, which can press the working rod downward and inward, which is equivalent to adding an inclined reinforcing rib to the working rod, making the position of the working rod more stable and reliable. The four sets of spring rods support the working rod from the side, which can effectively ensure that the working rod will not shift during the friction test, effectively improving the test accuracy and precision.

[0038] This device also includes a specific structure of spring rods, including a spring sleeve, a spring rod body, and spring components. The position and number of spring rods are also carefully considered. By rationally setting the position and number of spring rods, the clamping force of the spring rods is effectively increased, making the overall structure more reasonable.

[0039] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit the implementation of this utility model or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
