Description

Technical Field

[0001] The present application relates to the field of electric lifting table equipment, and in particular to a testing workbench for a lifting table push rod. Background Art

[0002] As the name suggests, a lifting table is a table that can be raised and lowered freely. One type is a sit-down lifting table, which has a small lifting range and is suitable for users of different heights. It is often used as a high-rise study table for growing children. Another type is a sit-stand lifting table, which has a large lifting range and can be used for both sitting and standing work. The lifting table mainly relies on the push rod to achieve lifting, so the quality of the push rod needs to be tested to ensure the quality of the push rod on each lifting table is stable.

[0003] A Chinese patent with announcement number CN216669237U discloses a push rod telescopic resistance test bench, including a workbench, on which a first mounting seat is slidably arranged, and a clamping assembly for clamping a sleeve and a driving member for driving the first mounting seat to move are also arranged on the workbench. The sleeve is clamped and fixed on the clamping assembly, and the axial direction of the sleeve is parallel to the moving direction of the first mounting seat. A second mounting seat for fixing the driving end of the screw rod is slidably arranged at one end of the first mounting seat away from the driving member, and the second mounting seat has the same sliding direction as the first mounting seat, and a force measuring member for testing the force value between the first mounting seat and the second mounting seat is arranged between the first mounting seat and the second mounting seat.

[0004] When using the above technology, only one push rod can be tested at a time, and the test efficiency is low. If multiple test devices are arranged, on the one hand, a large working space will be occupied, and on the other hand, multiple staff will be required to operate and observe, which will increase the investment cost of the test, and there are shortcomings. Utility Model Content

[0005] In order to improve the problem of low testing efficiency of a push rod, the present application provides a testing workbench for a lift table push rod.

[0006] The present application provides a test bench for a lifting table push rod, which adopts the following technical solution:

[0007] A test workbench for a push rod of a lifting table comprises a test bench, wherein a plurality of slide rails are arranged along the width direction of the test bench, a slide seat is slidably arranged between two adjacent slide rails and along the length direction of the slide rails, a plurality of fixed seats are arranged on the test bench, the fixed seats correspond to the slide seats one by one, the fixed seats are used to fix the rod body of the push rod, the slide seat is used to fix the protruding end of the push rod, and a driving component for driving the slide seat to slide and a test data output component for testing the performance of the push rod are provided on the test bench.

[0008] By adopting the above technical solution, workers fix multiple push rods on the fixed seat on the test bench in sequence, and fix the protruding ends of the push rods on the sliding seat, and then slide the sliding seat through the driving assembly.

[0012] By adopting the above technical solution, when the driving component drives the second slider to slide, the tension tester displays the tension value between the first slider and the second slider. At the same time, the first slider drives the extended end of the push rod to contract, so as to test the contraction distance of the extended end of the push rod under the tension size, and then compare it with the design standard to know whether the push rod is qualified.

[0013] Optionally, a plurality of position sensors are provided on the slide rail, and the plurality of position sensors are arranged along the length direction of the slide rail.

[0014] By adopting the above technical solution, workers can pass the extended end of the push rod through multiple position sensors, and then measure the change in tension of the tension tester at this distance.

[0015] Optionally, the driving assembly includes a driving cylinder disposed on the test bench and electrically connected to a control system, and the first sliding block is disposed on a piston rod of the driving cylinder.

[0016] By adopting the above technical solution, workers start the driving cylinder through the control system, and the piston rod of the driving cylinder contracts, so that the first slider pulls the second slider through the tensile tester, and the second slider compresses the push rod, thereby testing whether the quality of the push rod is qualified under pressure.

[0017] Optionally, the fixing seat includes a fixing plate, the fixing plate is provided with a placement slot for placing the shaft of the push rod, the fixing plate is bolted with a fixing bolt, and the fixing bolt is used to press the push rod onto the fixing plate.

[0018] By adopting the above technical solution, the worker places the push rod in the placement groove on the fixing plate, and then tightens the fixing bolt to achieve rapid installation and fixation of the push rod. The operation is simple and quick, which is conducive to improving the testing efficiency of the push rod.

[0019] Optionally, a clamping station is provided directly above the second sliding block, and the clamping station is used to fix the protruding end of the push rod.

[0020] By adopting the above technical solution, the possibility of the extended end of the push rod being separated from the second sliding block is reduced during testing, and the accuracy of the push rod test results is further improved.

[0021] Optionally, the driving cylinder is located below the test bench, a connecting plate is provided between the piston rod of the driving cylinder and the first sliding block, and an avoidance slot for the connecting plate to slide is provided on the test bench.

[0022] By adopting the above technical solution, the space area occupied by the driving cylinder on the test bench is reduced, the utilization rate of the space under the test bench is improved, and it is more convenient for workers to install the push rod for testing.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The worker places multiple push rods on the fixed seat on the test bench in sequence, and fixes the extended end of the push rod on the slide seat, and then slides the slide seat through the driving assembly. The test data output part outputs the test data of each push rod to the control system. One worker can operate and observe multiple push rods, and there is no need to arrange multiple test benches, which reduces the space occupation and is conducive to improving the test efficiency of the push rods;

[0025] 2. When the driving assembly drives the second slider to slide, the tension tester displays the tension value between the first slider and the second slider. At the same time, the first slider drives the extended end of the push rod to contract, so as to test the contraction distance of the extended end of the push rod under the tension. Then, by comparing with the design standard, it can be known whether the push rod is qualified.

[0026] 3. After the extended end of the push rod passes through multiple position sensors, the worker can measure the change in tension of the tension tester at this distance, and further test the difference between the pressure and the standard design pressure value of different push rods when their piston rods are continuously compressed, so as to determine whether the push rod is qualified, which is conducive to improving the accuracy of the test results.

Guide blocks 43 are welded on both sides of the first slider 41 and the second slider 42 along their sliding directions. Guide grooves 44 for the guide blocks 43 to slide are provided on both sides of the slide rail 3. A clamping station 8 is bolted directly above the second slider 42, and the clamping station 8 is used to fix the protruding end of the push rod 1.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The fixed seat 5 includes a fixed plate 51, a placement slot 52 for placing the rod body of the push rod 1 is opened on the fixed plate 51, a fixing bolt 53 is bolted on the fixed plate 51, and the fixing bolt 53 is used to press the push rod 1 onto the fixed plate 51.
