Description

Technical Field

[0001] The utility model relates to the technical field of sealant testing, in particular to a testing tooling for butyl hot melt sealant. Background Technique

[0002] Butyl hot melt sealant is a high-performance sealing material, which is composed of butyl rubber and auxiliary components, and has excellent sealing performance and adhesion. It becomes a flowing state when heated and solidifies into a gel state after cooling, and can effectively prevent the penetration of moisture, air and dust. Butyl hot melt sealant is widely used in the fields of construction, automobiles and electronics, providing lasting waterproof and sealing effects, and having good aging resistance and environmental protection.

[0003] When producing butyl hot melt sealant, it is necessary to conduct tensile tests on it to ensure its mechanical properties and use effects. At present, during the test, it is necessary to manually fix both ends of the sealant strip, and the sealant strip needs to be removed after the test structure. The removal and placement of the sealant strip both take a certain amount of time, which leads to a longer test time. Especially in the case of batch testing, the test efficiency will be reduced. Content of the Utility Model

[0004] The purpose of the utility model is to provide a testing tooling for butyl hot melt sealant that can improve the test efficiency in the case of batch testing.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A testing tooling for butyl hot melt sealant includes a bottom plate. A column is arranged on the upper surface of the bottom plate, and a top plate is installed at the top of the column. Four first mounting blocks are coaxially and arrayedly installed on the lower surface of the top plate. Four grooves are coaxially and arrayedly formed on the outer surface of the column. A first sliding rod is installed inside the groove. A slider is slidably installed on the outer surface of the first sliding rod. A first spring is sleeved on the outer surface of the first sliding rod, and both ends of the first spring are respectively abutted against the inner wall of the groove and the slider. A connecting block is installed on the outer surface of the slider, and a second mounting block is installed at the end of the connecting block. Fixing mechanisms are arranged at the ends of both the second mounting block and the first mounting block. An electric push rod is installed on the upper surface of the bottom plate. An insertion block is installed at the end of the telescopic end of the electric push rod. A slot is formed on the lower surface of the second mounting block, and a connecting mechanism is arranged inside the insertion block. A driving mechanism capable of driving the column to rotate is arranged inside the bottom plate.

[0007] It can be seen that after the two ends of the sealing strip are respectively fixed to the ends of the first mounting block and the second mounting block through the fixing mechanism, the electric push rod drives the insertion block to insert into the slot, and the quick connection is realized through the connection mechanism. Then, the electric push rod contracts to drive the sealing strip to stretch, so as to achieve the purpose of tensile testing. During the testing of the current sealing strip, workers can place and remove the sealing strip between the other three first mounting blocks and the second mounting blocks, improving the utilization rate of time. Therefore, the testing efficiency can be greatly improved in the case of batch testing. Moreover, this tooling only uses one electric push rod as the stretching power source, which can reduce costs and is convenient to use.

[0008] Further, the fixing mechanism includes a U-shaped block, a screw, a clamping block and a limiting rod. The clamping block is arranged inside the U-shaped block. The screw penetrates through the interior of the U-shaped block and is threadedly connected thereto. And the end of the screw is rotatably connected to the clamping block. Limiting rods are connected to the four corners of the outer surface of the clamping block, and the ends of the limiting rods penetrate to the outside of the U-shaped block.

[0009] After placing the end of the sealing strip between the U-shaped block and the clamping block, the screw can be rotated. Since the limiting rod limits the clamping block, the clamping block can move horizontally to clamp the end of the sealing strip, achieving the purpose of fixation.

[0010] Further, the connection mechanism includes an installation groove opened inside the insertion block. An activity plate is arranged inside the installation groove. A pressure rod and a wedge block are respectively installed on both sides of the outer surface of the activity plate. And the wedge block is adapted to the inner wall of the slot. A second sliding rod is installed inside the installation groove, and the installation groove is slidably installed on the outer surface of the second sliding rod. A second spring is sleeved on the outer surface of the second sliding rod, and both ends of the second spring are respectively abutted against the inner wall of the installation groove and the activity plate.

[0011] When the telescopic end of the electric push rod extends upward, it can drive the insertion block to insert into the slot. At the beginning of the insertion, the inclined surface of the wedge block and the inclined surface at the bottom of the slot are mutually extruded, which can drive the wedge block to contract into the installation groove. When the insertion block is completely inserted into the slot, the squeezed wedge block pops outwards under the push of the elastic force of the second spring and can be stuck at the inner wall on the upper side of the slot. Therefore, the purpose of quick connection is achieved. When it is necessary to pull out the insertion block from the slot, the electric push rod can be first started to contract downward by an appropriate distance, which drives the slider to slide downward and compress the first spring. Then, press the pressure rod inward. The pressure rod pushes the activity plate to move, which can drive the wedge block to contract into the installation groove. At this time, the second mounting block loses the connection with the insertion block, and the compressed first spring releases the elastic force, so as to drive the second mounting block to move upward and complete the purpose of separating from the insertion block.

[0012] Further, the driving mechanism includes an inner groove opened inside the bottom plate. A connecting shaft is rotatably connected inside the inner groove, and the top of the connecting shaft is connected to the lower surface of the column. A toothed ring is sleeved on the outer surface of the connecting shaft. A motor is installed inside the inner groove, and a gear is installed at the end of the output shaft of the motor. The gear is meshed with the toothed ring.

[0013] When the motor is started, its output shaft drives the gear to rotate. Since the gear is meshed with the toothed ring, the connecting shaft can be driven to rotate, and the column can be driven to rotate.

[0014] Further, a support rod is installed on the outer surface of the bottom plate, and a control panel is installed at the end of the support rod.

[0015] Through the arrangement of the support rod, it is convenient to observe and record the test data and control the test tooling.

[0016] Further, a ball is arranged on the upper surface of the column, and the ball contacts the bottom of the column.

[0017] Through the arrangement of the ball, the supporting ability of the bottom of the column can be improved, and the smoothness and stability during its rotation can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present utility model will be described in detail below with reference to the accompanying drawings.

[0024] As Figures 1-4 shown, a butyl hot melt sealant testing tooling includes a bottom plate 100. A column 101 is arranged on the upper surface of the bottom plate 100. A top plate 102 is installed at the top of the column 101. Four first mounting blocks 103 are coaxially and arrayedly installed on the lower surface of the top plate 102. Four grooves 104 are coaxially and arrayedly formed on the outer surface of the column 101. A first sliding rod 105 is installed inside the groove 104. A slider 106 is slidably installed on the outer surface of the first sliding rod 105. A first spring 107 is sleeved on the outer surface of the first sliding rod 105. Two ends of the first spring 107 are respectively abutted against the inner wall of the groove 104 and the slider 106. A connecting block 108 is installed on the outer surface of the slider 106. A second mounting block 109 is installed at the end of the connecting block 108. Fixing mechanisms 200 are arranged at the ends of both the second mounting block 109 and the first mounting block 103. An electric push rod 110 is installed on the upper surface of the bottom plate 100. A plug 111 is installed at the end of the telescopic end of the electric push rod 110. A slot 112 is formed on the lower surface of the second mounting block 109. A connecting mechanism 300 is arranged inside the plug 111. A driving mechanism 400 capable of driving the column 101 to rotate is arranged inside the bottom plate 100.

[0025] During use, first, both ends of the sealant strip are respectively fixed to the ends of the first mounting block 103 and the second mounting block 109 through the fixing mechanism 200. Then, the electric push rod 110 is started to drive the plug 111 to insert into the slot 112. Through the setting of the connecting mechanism 300, automatic fixed connection can be achieved after the plug 111 is inserted into the slot 112. Then, the electric push rod 110 drives the plug 111 to move downward to conduct a tensile test on the sealant strip and record the data. And during the current sealant strip test, workers can place and remove the sealant strip between the other three first mounting blocks 103 and the second mounting block 109, improving the utilization rate of time. After the test, the connection between the plug 111 and the slot 112 can be cancelled through the connecting mechanism 300. At this time, the compressed first spring 107 releases elastic force, which can drive the slider 106 and the second mounting block 109 to move upward and separate from the plug 111. Then, the driving mechanism 400 drives the column 101 to rotate 90 degrees, so that the pre-fixed sealant strip rotates to directly above the plug 111. Then, the electric push rod 110 is started to drive the plug 111 to insert into the slot 112. Subsequently, by repeating the above operations, the test efficiency can be greatly improved in the case of batch testing. And this tooling only uses one electric push rod 110 as the tensile power source, which can reduce costs and is convenient for use.

[0026] Specifically, the fixing mechanism 200 includes a U-shaped block 201, a screw 202, a clamping block 203 and a limiting rod 204. The clamping block 203 is arranged inside the U-shaped block 201. The screw 202 penetrates through the inside of the U-shaped block 201 and is threadedly connected thereto, and the end of the screw 202 is rotatably connected to the clamping block 203. Limiting rods 204 are connected to the four corners of the outer surface of the clamping block 203, and the ends of the limiting rods 204 penetrate to the outside of the U-shaped block 201. After placing the end of the sealing strip between the U-shaped block 201 and the clamping block 203, the screw 202 can be rotated. Since the limiting rod 204 limits the clamping block 203, the clamping block 203 can move horizontally and clamp the end of the sealing strip, achieving the purpose of fixation.

[0027] Specifically, the connecting mechanism 300 includes an installation groove 301 opened inside the insertion block 111. An active plate 302 is arranged inside the installation groove 301. A pressing rod 303 and a wedge-shaped block 304 are respectively installed on both sides of the outer surface of the active plate 302, and the wedge-shaped block 304 is adapted to the inner wall of the insertion slot 112. A second sliding rod 305 is installed inside the installation groove 301, and the installation groove 301 is slidably installed on the outer surface of the second sliding rod 305. A second spring 306 is sleeved on the outer surface of the second sliding rod 305, and both ends of the second spring 306 are in contact with the inner wall of the installation groove 301 and the active plate 302 respectively. When the telescopic end of the electric push rod 110 extends upward, it can drive the insertion block 111 to be inserted into the insertion slot 112. At the beginning of the insertion, the inclined surface of the wedge-shaped block 304 and the inclined surface at the bottom of the insertion slot 112 are mutually extruded, which can drive the wedge-shaped block 304 to contract into the installation groove 301. After the insertion block 111 is completely inserted into the insertion slot 112, the squeezed wedge-shaped block 304 pops out outward under the pushing force of the elastic force of the second spring 306 and can be stuck at the inner wall on the upper side of the insertion slot 112, thus achieving the purpose of quick connection; when it is necessary to pull out the insertion block 111 from the insertion slot 112, the electric push rod 110 can be first started to contract downward by an appropriate distance, so that it drives the slider 106 to slide downward and compress the first spring 107. Then, the pressing rod 303 is pressed inward, and the pressing rod 303 pushes the active plate 302 to move, which can drive the wedge-shaped block 304 to contract into the installation groove 301. At this time, the second installation block 109 loses its connection with the insertion block 111, and the compressed first spring 107 releases its elastic force, thus driving the second installation block 109 to move upward and completing the purpose of separating from the insertion block 111.

[0028] Specifically, the driving mechanism 400 includes an inner groove 401 formed inside the bottom plate 100. A connecting shaft 402 is rotatably connected inside the inner groove 401, and the top of the connecting shaft 402 is connected to the lower surface of the column 101. A toothed ring 403 is sleeved on the outer surface of the connecting shaft 402. A motor 404 is installed inside the inner groove 401. The end of the output shaft of the motor 404 is provided with a gear 405. The gear 405 is meshed with the toothed ring 403. When the motor 404 is started, its output shaft drives the gear 405 to rotate. Since the gear 405 and the toothed ring 403 are meshed with each other, the connecting shaft 402 can be driven to rotate, and the column 101 can be driven to rotate.

[0029] Specifically, a support rod 500 is installed on the outer surface of the bottom plate 100. A control panel 501 is installed at the end of the support rod 500. Through the arrangement of the support rod 500, it is convenient to observe and record the test data and control the test tooling.

[0030] Specifically, a ball 600 is arranged on the upper surface of the column 101. The ball 600 contacts the bottom of the column 101. Through the arrangement of the ball 600, the supporting ability of the bottom of the column 101 can be improved, and the smoothness and stability during its rotation can be improved.

[0031] The above is a detailed description of the present invention in combination with specific embodiments. It cannot be determined that the specific implementation manners of the present invention are only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several equivalent substitutions or obvious modifications are made, and the performance or uses are the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted by the present invention.
