Description

Technical Field

[0001] This utility model belongs to the field of glass fiber cloth testing technology, and specifically relates to a glass fiber cloth testing table. Background Technology

[0002] A fiberglass cloth testing station is a device specifically designed to inspect the quality of fiberglass cloth. It tests various properties of the fiberglass cloth to ensure it meets specific industry standards or customer requirements. Among existing tests for fiberglass cloth, the tensile test measures its tensile strength, aiming to determine its tensile limit value. Existing tensile testing stations typically have clamping mechanisms to hold the fiberglass cloth, applying a force in the opposite direction to stretch it, and using pressure sensors to acquire the ultimate pressure data at which the fiberglass cloth breaks. However, due to the fixed structure of existing testing stations, different clamps need to be changed when testing fiberglass cloth of different widths, resulting in significant time consumption. Therefore, a new structure is proposed to solve these problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figures 1 to 6 A glass fiber cloth testing station includes a clamping assembly 200 and a moving assembly 300. The clamping assembly 200 includes an upper clamp 210 and a lower clamp 220 for clamping the glass fiber cloth. The clamping assembly 200 is installed on the top of the testing station body 100.

[0030] The upper surface of the main body 100 of the testing table is provided with a disassembly and assembly slide groove 110 on the left and right sides respectively. A moving component 300 is installed above the disassembly and assembly slide groove 110. The moving component 300 includes a support plate 310 for supporting the clamping component 200.

[0031] The main body 100 of the testing station has a back plate on the rear side. Two sets of drive shafts 240 are installed through the front of the back plate. Two sets of reducers are installed on the rear side of the back plate. The output end of the reducer is connected to the rear side of the drive shaft 240 through a coupling.

[0032] The main body of the testing station 100 has a support base on the left and right sides of the rear side of the upper surface. Each of the two support bases has a shaft hole on its front. The positions of the two shaft holes are opposite to the positions of the two transmission shafts 240. A display is installed on the front of the back plate.

[0033] The longitudinal section of the disassembly and assembly slide 110 is a U-shaped structure. Several sets of positioning grooves 111 are opened from front to back on the lower inner surface of the disassembly and assembly slide 110. A scale line is vertically provided on the side of the disassembly and assembly slide 110 away from the center line of the main body 100 of the testing table.

[0034] The clamping assembly 200 has two sets of the same specifications. The two sets of clamping assemblies 200 are symmetrically installed on the left and right sides of the upper surface of the testing table body 100. The lower clamp 220 has a fixed shaft on the front side and a docking shaft 230 that docks with the transmission shaft 240 on the rear side.

[0035] The docking shaft 230 and the drive shaft 240 have the same radius and length. The front of the drive shaft 240 is recessed to form a docking groove. A fitting groove 241 is provided on the rear side of the docking groove. A docking rod is provided on the rear side of the docking shaft 230. A fitting magnetic plate 231 that fits and connects with the fitting groove 241 is provided on the rear side of the docking rod.

[0036] The lower clamp 220 is provided with a limiting block at the front and rear positions respectively. An electromagnetic brake rod 221 is embedded in the upper inner side of each limiting block. The top of the lower clamp 220 is recessed downward to form a pressure groove 222. Several sets of rubber bosses 223 are provided at the front and rear positions of the top of the lower clamp 220 respectively.

[0037] The bottom of the upper clamp 210 is provided with a pressure strip 212 that mates with the pressure groove 222, and a locking groove 211 that mates with and is fixed to the electromagnetic brake rod 221 is provided on the front and rear sides of the upper clamp 210 respectively.

[0038] The lower clamp 220 and the upper clamp 210 together form a cylindrical clamping assembly 200. The fixing shaft on the front side of the lower clamp 220 is placed inside the shaft hole 2 opened on the back of the support plate 310. A pressure sensor is installed inside the lower clamp 220.

[0039] A base plate 320 is provided on the front side below the support plate 310, and a sliding block 330 is provided below the support plate 310. The longitudinal cross-sectional shape of the sliding block 330 matches the longitudinal cross-sectional shape of the disassembly and assembly slide groove 110. A positioning screw 340 is screwed onto the top of the base plate 320.

[0040] The positioning screw 340 has a knob on top. The radius of the bottom of the positioning screw 340 matches the radius of the positioning groove 111. The interval between two adjacent sets of positioning grooves 111 is 5cm. The positions of several sets of positioning grooves 111 match the scale on the scale line.

[0041] Example 1: Please refer to Figures 1 to 6 In actual use, a reducer is installed on the left and right sides of the rear of the main body 100 of the testing platform. The front sides of the two reducers are each connected to a drive shaft 240 via a coupling. The front side of the drive shaft 240 penetrates the surface of the back plate on the rear side of the main body 100 of the testing platform and extends into the front side of the back plate. A clamping assembly 200 is installed on the left and right sides of the upper surface of the main body 100 of the testing platform. The clamping assembly 200 includes an upper clamp 210 and a lower clamp 220. A docking shaft 230 is provided on the rear side of the clamping assembly 200. The radius of the docking shaft 230 matches the radius of the drive shaft 240. The front of the drive shaft 240 is recessed to form a docking groove. A fitting groove 241 is opened on the rear side inside the docking groove. The surface material of the fitting groove 241 is iron. A... A docking rod is provided, and the specifications of the docking rod and the docking groove are matched. A fitting magnetic plate 231 with a toothed structure is provided on the rear side of the docking rod. The shape of the fitting magnetic plate 231 matches the shape of the fitting groove 241. A support base is provided on the left and right sides of the rear side of the upper surface of the detection table body 100. The docking shaft 230 passes through the inner side of the shaft hole opened on the front of the docking base and docks and fixes with the transmission shaft 240. It should be noted that after the fitting magnetic plate 231 and the fitting groove 241 are magnetically fixed, since no external force is applied along the direction of the clamping assembly 200, the docking shaft 230 and the transmission shaft 240 will not actively disengage. Secondly, through the design of the toothed structure of the fitting magnetic plate 231, the transmission can be carried out through the fitting groove 241, thereby driving the clamping assembly 200 to rotate through the fitting magnetic plate 231.

[0042] A disassembly / assembly slide groove 110 is vertically formed on the left and right sides of the upper surface of the testing platform. The front side of the disassembly / assembly slide groove 110 is connected to the front of the testing platform body 100. Several sets of positioning grooves 111 are formed sequentially from front to back on the lower inner surface of the disassembly / assembly slide groove 110. The longitudinal section of the disassembly / assembly slide groove 110 has a U-shaped structure. A scale line is provided on the side of the disassembly / assembly slide groove 110 away from the center line of the testing platform body 100. The interval between two adjacent sets of positioning grooves 111 is 5cm, and the scale unit on the scale line is 5cm. Therefore, the several sets of positioning grooves 111 are respectively aligned with the scale on the scale line, which is convenient for observation. The scale lines adjust the position of the moving component 300. The moving component 300 includes a support plate 310, a base plate 320, and a sliding block 330. The sliding block 330 is located inside the disassembly and assembly slide 110. The base plate 320 is located at the top of the disassembly and assembly slide 110. The support plate 310 is located at the rear of the top of the base plate 320. The support plate 310 has a shaft hole 2 on its front for placing the front fixing shaft of the clamping component 200. A positioning screw 340 is screwed onto the top of the base plate 320. The positioning screw 340 is rotated by a knob on its top. The radius of the bottom of the positioning screw 340 matches the radius of the positioning groove 111.

[0043] In actual use, two sets of reducers drive two sets of clamping components 200 to rotate in opposite directions, i.e., the left clamping component 200 rotates counterclockwise and the right clamping component 200 rotates clockwise, thereby winding and gradually tightening the fiberglass cloth between the two sets of clamping components 200. The pressure sensor inside the lower clamp 220 collects the pressure changes of the fiberglass cloth during the tightening process, and the pressure changes are displayed on the display set in the center of the back plate, so that the tester can easily observe and record them (the reducer, pressure sensor and display are all existing technologies, and their internal structure and working principle will not be described in detail here). Then, a tensile test is performed on the fiberglass cloth. After this, if it is necessary to perform tensile tests on fiberglass cloth of different widths, first, the knob can be rotated in the opposite direction to drive the bottom of the positioning screw 340 to disengage from the positioning groove 111, releasing the positioning effect of the moving component 300. Then, the moving component 300 is slid forward to remove it. Then, the clamp is held. Pull the outer side of component 200 forward to disengage the docking rod on the rear side of docking shaft 230 from the docking groove, and simultaneously disengage the fitting magnetic plate 231 from the fitting groove 241. Then remove the complete clamping component 200. Next, insert the docking rod on the rear side of the new clamping component 200 into the docking groove, and engage the fitting magnetic plate 231 with the fitting groove 241. Note that the specifications of the docking shaft 230 and the fixed shaft in clamping components 200 of different sizes are exactly the same. Then, lift the moving component 300 and slide the sliding block 330 along the disassembly and assembly slide groove 110 backward. Determine the position of the positioning groove 111 based on the relative position of the positioning screw 340 and the scale line. When the fixed shaft in the new clamping component 200 is placed inside the shaft hole, rotate the knob to drive the positioning screw 340 down and insert it into the shaft hole, thus completing the replacement of the new clamping component 200. Therefore, the final effect is to significantly improve the replacement efficiency, thereby greatly improving the detection efficiency.

[0044] Example 2: Please refer to Figure 3 , Figure 4 and Figure 5When installing the clamping assembly 200, the clamping assembly 200 includes a lower clamp 220 and an upper clamp 210. A limiting block is provided at the front and rear positions of the lower clamp 220. The docking shaft 230 is located at the center of the back side of the rear limiting block, and the fixing shaft is located at the center of the front side of the front limiting block. The placement of the docking shaft 230 and the fixing shaft is described in detail in Embodiment 1 and will not be repeated here. An electromagnetic brake rod 221 is embedded in the upper inner side of each of the two sets of limiting blocks (the electromagnetic brake rod 221 is prior art, and its internal structure and working principle are not described here). (To be repeated) The lower clamp 220 has a pressure groove 222 on its top, and several sets of rubber protrusions 223 for increasing friction are provided on the front and rear positions of the top of the lower clamp 220. The upper clamp 210 has a pressure strip 212 that matches the pressure groove 222 at its bottom. The lower clamp 220 has a locking groove 211 that matches the electromagnetic brake rod 221 on its front and rear sides. The lower clamp 220 and the upper clamp 210 together form a cylindrical clamping assembly 200, and the outer sides of the lower clamp 220 and the upper clamp 210 are covered with a rubber layer.

[0045] In actual use, since the specifications of the two sets of clamping components 200 are the same, the clamping component 200 on the upper right side of the main body 100 of the testing table will be described here. The other set will be described in the same way. First, the docking shaft 230 on the rear side of the lower clamp 220 is passed through the shaft hole one and docked and fixed with the docking shaft 230. Then, the sliding component 300 is slid to place the fixing shaft on the front side of the lower clamp 220 into the shaft hole two. The sliding component 300 is then fixed. Next, the fiberglass cloth to be tested for tensile strength is picked up and laid flat on the upper surface of the lower clamp 220. The upper clamp 210 is picked up and the pressure strip 212 is inserted downward into the pressure groove 222, thereby squeezing the part of the fiberglass cloth above the pressure groove 222 into the pressure groove 222. At this time, the upper clamp 210 is placed on top of the lower clamp 220. Then, two sets of electromagnetic brake rods 221 are inserted into two sets of locking slots 211 respectively, thereby fixing the lower clamp 220 and the upper clamp 210. After fixing, the fiberglass cloth is between the upper clamp 210 and the lower clamp 220, and the lower surface of the fiberglass cloth is in close contact with several sets of rubber protrusions 223. During the tensile test, the fiberglass cloth is rolled up on the outside of the two sets of clamping components 200 under the action of the two sets of counter-rotating clamping components 200. Over time, the fiberglass cloth is finally tensioned between the two sets of clamping components 200. As the rotation continues, the tension continues to increase, and then the fiberglass cloth can be tested for tensile strength. Therefore, the final effect is that the fiberglass cloth can be tightly clamped inside the clamping components 200, which increases the clamping stability of the fiberglass cloth.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
