[0001] The utility model relates to a double-station spring testing machine, belonging to the technical field of spring tension and compression testing. Background Art
[0002] The microcomputer-controlled spring tension and compression testing machine is a special instrument for testing the deformation and load relationship characteristics of tension and compression springs. It is suitable for strength testing of various springs, analysis of mechanical properties and process capability index.
[0003] Existing microcomputer-controlled spring tension and compression testing machines all adopt single-station, occupy a large space, have low working efficiency and high production cost.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a double-station spring testing machine, which solves the problem that the microcomputer-controlled spring tension and compression testing machines in the prior art all adopt a single station, occupy a large space, have low working efficiency and high production cost.
[0006] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a double-station spring testing machine, comprising a base, a cover shell bolted to the base, a computer for controlling spring testing and data feedback arranged on the cover shell, a frame body also arranged in the cover shell, the frame body bolted to the base, two tension and pressure sensors with different ranges slidably connected to the frame body, a pressure testing module is arranged between the two tension and pressure sensors and the base, a tension testing module is arranged between the two tension and pressure sensors and the top of the frame body, a driving mechanism for driving the tension and pressure sensors to slide is also arranged on the frame body, and the computer and the driving mechanism are electrically connected.
[0007] By adopting the above technical scheme, when it is necessary to test the spring, the staff first places the spring to be tested in the pressure test module or the tension test module according to the test needs, and then the staff can issue a spring test instruction to the driving mechanism through the computer, and the driving mechanism drives two tension and pressure sensors of different ranges to rise or fall at the same time according to the instruction, and then the tension and pressure sensor will feed back the collected data to the computer, and the computer will display the processed data to the staff on the display screen. The setting of two tension and pressure sensors of different ranges, on the one hand, forms two pressure test modules and two tension test modules, so that the utility model can test four springs at the same time; on the other hand, it allows the staff to freely select tension and pressure sensors of different ranges according to the physical properties of the spring to be tested, thereby expanding the scope of the spring test, and more springs can be tested in the same working space, which not only saves the space occupied by the equipment and improves the work efficiency, but also reduces the production cost, thereby helping the enterprise save expenditure.
[0008] The utility model is further configured as follows: a frame includes a bottom plate, a back plate is connected to the bottom plate by vertical bolts on one side, a plurality of support columns are connected to the bottom plate by vertical bolts on the other side, a top plate is connected to the back plate and the top of the support columns by bolts, a driving mechanism includes a screw rod rotatably connected between the top plate and the bottom plate, a sliding plate is threadedly connected to the screw rod, slide rails are bolted on both sides of the back plate, the sliding plate is slidably connected to the slide rails, a tension and pressure sensor is arranged on the sliding plate, the driving mechanism also includes a driving member for driving the screw rod to rotate, the driving member includes a motor bolted to the top plate, a rotating shaft is arranged at one end of the motor, one end of the rotating shaft extends out of the top plate and is connected to a synchronous wheel 1 through a flat key, one end of the screw rod extends out of the top plate and is connected to a synchronous wheel 2 through a flat key, and a synchronous belt is sleeved on the synchronous wheel 1 and the synchronous wheel 2.
[0009] By adopting the above technical solution, when the test instruction is transmitted to the motor, the motor rotates forward or reverse according to the test instruction, and the shaft rotates accordingly. The rotation of the shaft drives the synchronous wheel 1 to rotate, the rotation of the synchronous wheel 1 drives the synchronous belt to rotate, the rotation of the synchronous belt drives the synchronous wheel 2 to rotate, the rotation of the synchronous wheel 2 drives the screw to rotate, and the rotation of the screw makes the sliding plate tend to rotate accordingly. Due to the limiting effect of the slide rail on the sliding plate, the rotation of the sliding plate is limited, so that the sliding plate can only move axially on the screw, and the tension and pressure sensor on the sliding plate also moves axially accordingly, finally realizing the test function of the spring, and the operation is convenient. Among them, the setting of the back plate and a number of support rods ensures the stability of the frame structure, thereby ensuring the stable operation of the drive mechanism, and the drive mechanism can simultaneously control the rise and fall of the two tension and pressure sensors, thereby improving work efficiency.
[0010] The utility model is further configured as follows: the pressure test module includes a pressure plate fixed to the bottom of the tensile pressure sensor, two pressure seats corresponding to the two pressure plates are fixed on the base, the tensile test module includes a hook 1 fixed to the top of the tensile pressure sensor, two connecting blocks are bolted to the position of the top plate relative to the two hooks 1, and a hook 2 is bolted to the bottom of the connecting block.
[0011] By adopting the above technical solution, when it is necessary to test the tensile or compressive properties of the spring, the staff can install the two ends of the spring to be tested on hook one and hook two respectively, or place the spring to be tested vertically on the pressure seat, and then control the motor to rotate through the computer, the motor rotation drives the screw rod to rotate, the screw rod rotation drives the sliding plate to move axially, the axial movement of the sliding plate drives the tension and pressure sensor to move axially, thereby stretching or compressing the spring to be tested to achieve the test effect, so that the staff can freely select the corresponding test module according to the test requirements, which is convenient for the staff to test.
[0012] The utility model is further configured as follows: a groove is provided on the pressure seat, a support seat is fixed in the groove, the support seat is in a truncated cone shape, and the upper top surface is flush with the upper top surface of the pressure seat.
[0013] By adopting the above technical solution, when it is necessary to test the compression resistance of the spring, the staff can place the spring sleeve on the support seat. The setting of the truncated cone-shaped support seat can not only make the spring placement more stable, but also can be used for the placement of springs of different sizes. In addition, the top surface of the support seat is flush with the top surface of the pressure seat, thereby avoiding the situation where some springs have not been fully compressed yet, but the support seat presses against the pressure plate first, thereby ensuring the accuracy of the spring compression resistance test.
[0014] The utility model is further configured as follows: a foldable accordion-type dust cover is fixed between the connecting block and the tension and pressure sensor, and between the tension and pressure sensor and the base.
[0015] By adopting the above technical solution, the provision of the dust cover prevents external dust from entering the interior of the cover shell, thereby ensuring the stable operation of the double-station spring testing machine.
[0016] The beneficial effect of the utility model is that when it is necessary to test a spring, the staff first places the tested spring in a pressure test module or a tension test module according to the test needs, and then the staff can issue a spring test instruction to the driving mechanism through a computer, and the driving mechanism drives two tension and pressure sensors of different ranges to rise or fall at the same time according to the instruction, and then the tension and pressure sensor feeds back the collected data to the computer, and the computer displays the processed data to the staff on the display screen. The setting of two tension and pressure sensors of different ranges, on the one hand, forms two pressure test modules and two tension test modules, so that the utility model can test four springs at the same time; on the other hand, it allows the staff to freely select tension and pressure sensors of different ranges according to the physical properties of the tested spring, thereby expanding the scope of the spring test, and more springs can be tested in the same working space, which not only saves the space occupied by the equipment and improves the work efficiency, but also reduces the production cost, thereby helping the enterprise save expenditure.

DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.
[0024] like Figure 1 and Figure 2 As shown, a double-station spring testing machine includes a base 1, a cover shell 20 is bolted to the base 1, a computer 21 for controlling spring testing and data feedback is arranged on the cover shell 20, a frame 2 is also arranged in the cover shell 20, the frame 2 is bolted to the base 1, two tension and pressure sensors 10 with different ranges are slidably connected to the frame 2, a pressure test module 22 is arranged between the two tension and pressure sensors 10 and the base 1, a tension test module 23 is arranged between the two tension and pressure sensors 10 and the top of the frame 2, a driving mechanism for driving the tension and pressure sensors 10 to slide is also arranged on the frame 2, and the computer and the driving mechanism are electrically connected.
[0025] When it is necessary to test the spring, the staff first places the spring to be tested in the pressure test module 22 or the tension test module 23 according to the test requirements. Then the staff can issue a spring test instruction to the driving mechanism through the computer 21. The driving mechanism drives two tension and pressure sensors 10 of different ranges to rise or fall at the same time according to the instruction. Then the tension and pressure sensor 10 feeds back the collected data to the computer 21, and the computer 21 displays the processed data to the staff on the display screen.
[0026] The setting of two tension and pressure sensors 10 with different ranges, on the one hand, forms two pressure test modules 22 and two tension test modules 23, so that the utility model can test four springs at the same time; on the other hand, it allows the staff to freely select tension and pressure sensors 10 with different ranges according to the physical properties of the spring to be tested, thereby expanding the scope of spring testing and more springs can be tested in the same working space, which not only saves the space occupied by the equipment and improves work efficiency, but also reduces production costs, thereby helping enterprises save expenses.
[0027] like Figure 2 and Figure 3 As shown, the frame 2 includes a bottom plate 201, one side of the bottom plate 201 is vertically bolted with a back plate 202, the other side is vertically bolted with a plurality of support columns 203, the back plate 202 and the top of the support columns 203 are bolted with a top plate 204, the driving mechanism includes a screw rod 6 rotatably connected between the top plate 204 and the bottom plate 201, the screw rod 6 is threadedly connected with a sliding plate 9, both sides of the back plate 202 are bolted with slide rails 11, the sliding plate 9 is slidably connected to the slide rails 11, the tension and pressure sensor 10 is arranged on the sliding plate 9, the driving mechanism also includes a driving member for driving the screw rod 6 to rotate, the driving member includes a motor 3 bolted to the top plate 204, one end of the motor 3 is provided with a rotating shaft 4, one end of the rotating shaft 4 extends out of the top plate 204 and is connected to a synchronous wheel 1 5 through a flat key, one end of the screw rod 6 extends out of the top plate 204 and is connected to a synchronous wheel 2 7 through a flat key, and a synchronous belt 8 is sleeved on the synchronous wheel 1 5 and the synchronous wheel 2 7.
[0028] When the test instruction is transmitted to the motor 3, the motor 3 rotates forward or reverse according to the test instruction, and the rotating shaft 4 rotates accordingly. The rotation of the rotating shaft 4 drives the synchronous wheel 1 5 to rotate. The rotation of the synchronous wheel 1 5 drives the synchronous belt 8 to rotate. The rotation of the synchronous belt 8 drives the synchronous wheel 2 7 to rotate. The rotation of the synchronous wheel 2 7 drives the screw rod 6 to rotate. The rotation of the screw rod 6 makes the sliding plate 9 tend to rotate accordingly. Due to the limiting effect of the slide rail 11 on the sliding plate 9, the rotation of the sliding plate 9 is restricted, so that the sliding plate 9 can only move axially on the screw rod 6, and the tension and pressure sensor 10 on the sliding plate 9 also moves axially accordingly, finally realizing the test function of the spring, and the operation is convenient.
[0029] The arrangement of the back plate 202 and a plurality of support rods ensures the stability of the frame 2 structure, thereby ensuring the stable operation of the driving mechanism, and the driving mechanism can simultaneously control the rise and fall of the two tension and pressure sensors 10, thereby improving the working efficiency.
[0030] like Figure 2As shown, the pressure test module 22 includes a pressure plate 12 fixed to the bottom of the tension pressure sensor 10, and two pressure seats 13 corresponding to the two pressure plates 12 are fixed on the base 1. The tension test module 23 includes a hook 14 fixed to the top of the tension pressure sensor 10, and the top plate 204 is bolted to two connecting blocks 15 at the position relative to the two hooks 14, and the bottom of the connecting block 15 is bolted to a hook 2 16.
[0031] When it is necessary to test the tensile or compressive properties of the spring, the staff can install the two ends of the tested spring on hook 14 and hook 2 16 respectively, or place the tested spring vertically on the pressure seat 13, and then control the motor 3 to rotate through the computer 21. The rotation of the motor 3 drives the screw rod 6 to rotate, and the rotation of the screw rod 6 drives the sliding plate 9 to move axially. The axial movement of the sliding plate 9 drives the tensile pressure sensor 10 to move axially, thereby stretching or compressing the tested spring to achieve the test effect. Therefore, the staff can freely select the corresponding test module according to the test requirements, which is convenient for the staff to test.
[0032] like Figure 4 and Figure 5 As shown, a groove 17 is provided on the pressure seat 13, and a support seat 18 is fixed in the groove 17. The support seat 18 is truncated cone-shaped and its upper top surface is flush with the upper top surface of the pressure seat 13. When the compression resistance of the spring needs to be tested, the staff can put the spring sleeve on the support seat 18. The setting of the truncated cone-shaped support seat 18 can not only make the spring placement more stable, but also can be used for the placement of springs of different sizes. In addition, the upper top surface of the support seat 18 is flush with the upper top surface of the pressure seat 13, thereby avoiding the situation that some springs have not been fully compressed, and the support seat 18 presses against the pressure plate 12 first, thereby ensuring the accuracy of the spring compression resistance test.
[0033] like Figure 1 and Figure 2 As shown, a foldable accordion-type dust cover 19 is fixed between the connecting block 15 and the tension and pressure sensor 10, and between the tension and pressure sensor 10 and the base 1. The setting of the dust cover 19 prevents external dust from entering the interior of the cover 20, thereby ensuring the stable operation of the double-station spring testing machine.
[0034] Working principle:
[0035] When it is necessary to test the spring, the staff selects the test modules and their quantity required according to the test needs, and then the two ends of the tested spring can be installed on the hook 14 and the hook 2 16 respectively, or the tested spring can be placed vertically on the pressure seat 13, and then the test command is issued to the motor 3 through the computer 21. The motor 3 rotates forward or reversely according to the test command, and the shaft 4 rotates accordingly. The rotation of the shaft 4 drives the synchronous wheel 1 5 to rotate, and the rotation of the synchronous wheel 1 5 drives the synchronous belt 8 to rotate. The rotation of the synchronous belt 8 drives the synchronous wheel 2 7 to rotate, and the rotation of the synchronous wheel 2 7 drives the screw rod 6 to rotate. The rotation of the screw rod 6 makes the sliding plate 9 tend to rotate accordingly. Due to the limiting effect of the slide rail 11 on the sliding plate 9, the rotation of the sliding plate 9 is limited, so that the sliding plate 9 can only move axially on the screw rod 6, and the tension and pressure sensor 10 on the sliding plate 9 also moves axially accordingly, thereby stretching or compressing the tested spring to achieve the test effect. Finally, the tension and pressure sensor 10 feeds back the collected data to the computer 21, and the computer 21 displays the processed data to the staff on the display screen.
[0036] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments.
