Description

Technical Field

[0001] This application relates to the field of mechanical testing equipment technology, and in particular to a digital display push-pull force testing device. Background Technology

[0002] Epoxy powder encapsulation is a polymer composite material based on epoxy resin, mainly composed of epoxy resin, curing agent, inorganic filler, and other additives. It is manufactured through processes such as mixing, compounding, pulverizing, and grading, and is a thermosetting powder material that requires hot melt application. The main purpose of the epoxy powder encapsulation fracture test is to determine the epoxy powder coating's resistance to fracture under external force and to understand its behavior during the fracture process.

[0003] A push-pull force testing fixture is disclosed in the prior art, which includes a base, a test platform on one side of the base, a threaded rod on the other side of the base, and fixed rods on both sides of the threaded rod. The ends of the fixed rods are fixed to the fixed ends. The threaded rod is rotatably inserted into the through hole in the middle of the fixed ends. There is a threaded pin at the lower part of the fixed ends. The threaded pin has a threaded hole in the middle that mates with the threaded rod. The threaded pins on both sides of the threaded hole have guide holes that mate with the fixed rods. A push-pull force gauge is fixed on one side of the threaded pin. The force measuring end of the push-pull force gauge corresponds to the test platform.

[0004] Regarding the aforementioned technologies, in actual production, epoxy powder encapsulants are usually made into various sizes and specifications of sheets according to requirements. When testing the fracture resistance, the required support point spacing is different for sheets of different sizes and specifications. However, the push-pull force testing fixtures disclosed in the prior art can only provide support points with a fixed spacing, which cannot meet the fracture resistance testing requirements of epoxy powder encapsulants of various sizes and specifications. Utility Model Content

[0005] In order to meet the needs of testing the fracture resistance of epoxy powder encapsulants of various sizes and specifications, this application provides a digital push-pull force testing device.

[0006] The digital display push-pull force testing device provided in this application adopts the following technical solution:

[0007] A digital push-pull force testing device, comprising:

[0008] The test instrument itself;

[0009] The mounting base is connected to the main body of the testing instrument;

[0010] Two sliding blocks are provided. The fixed base has a sliding groove. The sliding blocks slide in the sliding groove. The sliding blocks are connected to the sliding blocks. The top walls of the two support blocks are horizontal and coplanar.

[0011] A fixing member for fixing the sliding block, the fixing member being connected to the fixing base and the sliding block.

[0012] By adopting the above technical solution, the designed digital push-pull force testing device can apply mechanical pressure to the epoxy powder encapsulation material placed on the support block and record the external force value when fracture occurs through the test instrument body. The fixed seat can provide support and sliding foundation for the sliding block. The sliding block can fix the support block and realize the adjustment of the distance between the two support blocks. It can adapt to the fracture resistance test requirements of epoxy powder encapsulation materials of various sizes and specifications. The fastener can fix the support block.

[0013] In one specific implementation, the bottom wall of the support block is slidably connected to the top wall of the fixed seat.

[0014] By adopting the above technical solution, the sliding stability of the support block can be increased.

[0015] In one specific implementation, the fixing member includes two fixing bolts, which are threadedly connected to the sliding block and pass through the sliding block to abut against the bottom wall of the sliding groove. The width of the sliding groove gradually decreases from bottom to top.

[0016] By adopting the above technical solution, the designed fastener, through the use of a fastening bolt and a sliding groove that is narrow at the top and wide at the bottom, can achieve relative stillness between the sliding block and the fixed seat, thereby preventing changes due to external forces after the distance between the two support blocks is determined.

[0017] In one specific implementation, the fixed base is threaded with two anti-loosening bolts, the sliding block is located between the two anti-loosening bolts, and one end of the anti-loosening bolt extends into the sliding groove.

[0018] By adopting the above technical solution, the designed anti-loosening bolt can prevent the sliding block from sliding in the sliding groove.

[0019] In one specific implementation scheme, a scale is also included, which is affixed to the fixing base, the setting direction of the scale is consistent with the sliding direction of the sliding block, and the anti-loosening bolt passes through the scale.

[0020] By adopting the above technical solution, the designed scale can quickly determine the distance between two support blocks.

[0021] In one specific implementation, a level bubble meter is also included, which is embedded in the mounting base and is located on the same side as the scale.

[0022] By adopting the above technical solution, the designed horizontal bubble meter can quickly determine whether the top walls of the two support blocks are in a horizontal state, thereby ensuring the accuracy of the test data during testing.

[0023] In one specific implementation, the adsorption and fixation mechanism includes:

[0024] A rubber ring is provided, and the fixing base has multiple adsorption holes. The rubber ring is embedded in one end of the adsorption holes near the bottom wall of the fixing base.

[0025] A sealing plug is slidably connected within the adsorption hole, and the sealing plug divides the adsorption hole into two sections;

[0026] Multiple driving components are provided, which are connected to the fixed base and the sealing plug, for raising and lowering the sealing plug within the adsorption hole.

[0027] By adopting the above technical solution, the designed adsorption and fixing mechanism, through the cooperation of rubber rings, sealing plugs and driving components, can achieve relative fixation between the fixing seat and the test instrument body, avoiding displacement of the fixing seat caused by vibration during operation of the test instrument body.

[0028] In one specific implementation, the drive includes:

[0029] A pull rod extends into the fixed base and passes through the adsorption hole, and multiple triangular protrusions are formed on the pull rod. A rectangular strip is connected to the top wall of the sealing plug, and the inclined surface of the triangular protrusions slides in contact with the rectangular strip.

[0030] A drive bolt is threadedly connected to the fixed seat and rotatably connected to one end of the pull rod.

[0031] By adopting the above technical solution, the designed driving component, through the cooperation of driving bolts, pull rods and triangular protrusions, can make the sealing plug rise and fall, thereby realizing the adsorption and fixation or release and unlocking between the fixed seat and the test instrument body.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0043] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0044] This application discloses a digital display push-pull force testing device.

[0045] Reference Figure 1 and Figure 2A digital push-pull force testing device includes a tester body 1, a fixed base 2, a sliding block 3, and a support block 4. The tester body 1 specifically includes a support base, a column, a probe, a display module, and a drive module. The drive module causes the probe to rise and fall until it contacts the sample. The display module displays and records the force value applied to the probe.

[0046] Reference Figure 1 and Figure 2 The fixed base 2 is connected to the support base, and the probe is located directly above the area where the fixed base 2 is located. There are two sliding blocks 3 and two support blocks 4. The fixed base 2 has a strip-shaped sliding groove 21. The sliding block 3 slides in the sliding groove 21 along the opening direction of the sliding groove 21. The support block 4 is welded and fixed to the sliding block 3, and the top wall of the support block 4 is set horizontally. The top walls of the two support blocks 4 are set coplanarly. Specifically, the bottom wall of the support block 4 is slidably connected to the top wall of the fixed base 2.

[0047] Reference Figure 2 It also includes a fixing member 5, which is connected to the fixing seat 2 and the sliding block 3. Specifically, the fixing member 5 includes two fixing bolts 51, which are threaded to the bottom wall of the sliding block 3 and pass through the sliding block 3 and abut against the bottom wall of the sliding groove 21. The width of the sliding groove 21 gradually decreases from bottom to top. The shape of the sliding block 3 is adapted to the cross-sectional shape of the sliding groove 21. By turning the fixing bolts 51, the sliding block 3 and the fixing seat 2 can be made to remain relatively stationary.

[0048] Reference Figure 3 Furthermore, the fixed base 2 is threaded with two anti-loosening bolts 6, and the sliding block 3 is located in the area between the two anti-loosening bolts 6, with one end of the anti-loosening bolt 6 extending into the sliding groove 21, thereby preventing the sliding block 3 from slipping out of the sliding groove 21 when adjusting the sliding block 3.

[0049] Reference Figure 3 Furthermore, it also includes a scale 7, which is attached to the fixed base 2, and the setting direction of the scale 7 is consistent with the sliding direction of the sliding block 3. The anti-disengagement bolt 6 passes through the scale 7, thereby fixing the scale 7 to the fixed base 2. In addition, a level bubble meter 8 is also embedded and fixed on the fixed base 2. The level bubble meter 8 and the scale 7 are on the same side of the fixed base 2, so as to facilitate the observation of the levelness of the fixed base 2 and the distance between the two sliding blocks 3 at one time.

[0050] Reference Figure 4 and Figure 5Since the drive module is generally a manual wheel, the support may vibrate when the manual wheel is operated, which will cause the relative position between the fixed seat 2 and the probe to change. Therefore, an adsorption fixing mechanism 9 is also included. The adsorption fixing mechanism 9 includes a rubber ring 91, a sealing plug 92 and multiple drive components 93. Multiple adsorption holes 22 are provided on the fixed seat 2. The multiple adsorption holes 22 are divided into two groups and the two groups of adsorption holes 22 are arranged in a straight line. The lower end of the adsorption hole 22 is through. The rubber ring 91 is embedded in the adsorption hole 22 near the bottom wall of the fixed seat 2 and can abut against the support.

[0051] Reference Figure 5 and Figure 6 There are multiple sealing plugs 92, which are slidably connected to the adsorption holes 22 and divide the adsorption holes 22 into two sections. The driving component 93 is connected to the fixed base 2 and the sealing plug 92, and is used to raise and lower the sealing plug 92 within the adsorption holes 22. Specifically, the driving component 93 includes a pull rod 931 and a driving bolt 933. The pull rod 931 extends into the fixed base 2 and passes through multiple adsorption holes 22 on the same side. Multiple triangular protrusions 932 are welded and fixed on the pull rod 931. A rectangular strip is welded and fixed on the top wall of the sealing plug 92. The triangular protrusions 932 pass through the inner cavity of the rectangular strip, and the inclined surface of the triangular protrusions 932 can slide in contact with the top wall of the inner cavity of the rectangular strip. The driving bolt 933 is threadedly connected to the fixed base 2 and is rotatably connected to one end of the pull rod 931.

[0052] The implementation principle of the digital push-pull force testing device in this application embodiment is as follows: First, place the fixed seat 2 on the support seat and make the probe directly above the fixed seat 2. Then, turn the drive bolt 933. While the drive bolt 933 rotates, it drives the pull rod 931 and the triangular protrusion 932 to move horizontally. The inclined surface of the triangular protrusion 932 applies force to the rectangular strip, causing the sealing plug 92 to rise, thereby reducing the air pressure in the area below the sealing plug 92. The fixed seat 2 and the support seat are then adsorbed and fixed.

[0053] Then apply force to the support block 4, and the support block 4 applies force to the sliding block 3 so that the sliding block 3 slides in the sliding groove 21. Observe the scale on the scale 7 until the distance between the two support blocks 4 matches the size specification of the current sample. Then tighten the fixing bolt 51 so that the sliding block 3 remains relatively stationary on the fixing seat 2. Then place the epoxy powder encapsulant on the two support blocks 4 and start the fracture resistance test.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
