Description

Technical Field

[0001] The invention relates to the technical field of electric push rod drive device testing equipment, in particular to an electric push rod testing equipment with vibration detection. Background Art

[0002] The electric push rod is a universal auxiliary drive device, which is widely used in photovoltaic, electric power, machinery, metallurgy, transportation, mining, petroleum, chemical industry, lifting, transportation, construction and other industries. It has the characteristics of simple structure, reliable performance, sensitive movement, smooth operation, good push-pull force, good environmental applicability, etc. During the use of the electric push rod, due to the reciprocating motion of the center screw, frequent friction will generate heat. The screw processing accuracy and assembly accuracy play a key role. Quality problems of the screw processing accuracy and assembly accuracy will cause the electric push rod to jam and fail, which will directly affect the operation of the equipment. Therefore, the assembled electric push rod needs to be tested and can only be shipped after passing the test.

[0003] Traditional electric push rod inspection is a sampling offline inspection. Large-scale inspection of electric push rods is time-consuming and consumes a lot of manpower and material resources. Because the entire batch cannot be inspected, defective electric push rods will appear, and unstable quality of electric push rods often occurs.

[0004] Therefore, in order to conduct full batch testing of electric push rods, prevent the outflow of unqualified products, and improve production quality, an electric push rod testing equipment capable of large-scale online testing is needed. Summary of the invention

[0005] The object of the present invention is to provide an electric push rod testing device with vibration detection to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: the electric push rod testing equipment includes a base, a test bench assembly, a tooling assembly, a reflux assembly, a displacement assembly, a locking assembly, and a detection system. The test bench assembly is fastened to the base, the displacement assembly is fastened to the base, the reflux assembly is fastened to the base, the reflux assembly is located on both sides of the base, the tooling assembly is slidably connected to the displacement assembly, the displacement assembly includes a first guide rail, the first guide rail is fastened to the base, the tooling assembly is slidably connected to the first guide rail, the first guide rail is provided with two groups, the locking assembly is fastened to the base, the detection system is fastened to the base, the tooling assembly and the test bench assembly are electrically connected to the detection system, the electric push rod is fastened to the test bench assembly and the tooling assembly, and the locking assembly abuts against the tooling assembly.

[0007] The base is the installation foundation of each component. The test bench component is used to measure the thrust of the electric push rod. The tooling component is used to fix the electric push rod. The reflux component is used to drive the tooling component for transportation. The displacement component is used to move the tooling component. The locking component is used to fix the tooling component in the detection position. The detection system is used to control each component. During the detection, the electric push rod is first fixed to the tooling component, and then the tooling component is used to slide along the first guide rail to drive the electric push rod to the position of the test bench component. The locking component is actuated to fix the tooling component in the detection position. , fix the electric push rod and the test bench assembly, and perform a thrust test. After the test is completed, the electric push rod is disengaged from the test bench assembly, the locking assembly releases the tooling assembly, and the tooling assembly drives the electric push rod to leave the detection position. The detection system determines the qualified and unqualified electric push rods, and classifies and places them at subsequent workstations. By setting two sets of first guide rails, the tooling assembly can return to the detection position driven by the reflux assembly. One set of first guide rails is used to move the tooling assembly, and the other set of first guide rails is used to detect the electric push rod, thereby realizing the detection cycle and making the detection process more convenient.

[0008] Furthermore, several groups of test bench components and tooling components are arranged along the direction of the first guide rail.

[0009] By setting up several groups of test bench components and tooling components, the detection efficiency can be improved and the cost can be reduced.

[0010] As shown in the figures, the tooling assembly includes a tooling seat, a mobile module, a first fixed seat, a clamping seat, and a vibration measuring device. The tooling seat is transmission-connected to the mobile module, the mobile module is slidingly connected to the first guide rail, the first fixed seat is fastened to the tooling seat, the clamping seat is fastened to the tooling seat, the clamping seat is fastened to the tooling seat, the vibration measuring device is fastened to the clamping seat, the vibration measuring device is electrically connected to the detection system, the electric push rod is fastened to the first fixed seat, and the electric push rod is clamped to the clamping seat.

[0011] The tooling seat provides an installation basis for the first fixed seat and the clamping seat. During testing, the bottom end of the electric push rod is fixed to the first fixed seat by a pin shaft, and the rod body of the electric push rod is clamped on the clamping seat, which plays a guiding role for the electric push rod and moves the module, thereby driving the tooling seat to move along the first guide rail, and driving the electric push rod to the position of the test bench assembly for testing. In order to detect the vibration of the electric push rod during work, the transmissibility of vibration is utilized. By fixing the vibration measuring device on the clamping seat, the vibration of the electric push rod can be detected, and the signal can be transmitted to the detection system for analysis to determine whether the tested electric push rod is qualified.

[0012] Furthermore, the vibration measuring device includes a shell, a permanent magnet, a spring, and a coil. The shell is fastened to the clamping seat. A transmission chamber is provided in the shell. The permanent magnet is located in the transmission chamber. The spring is fastened to the shell. The spring suspends the permanent magnet in the transmission chamber. The coil is wound around the outside of the transmission chamber. The coil is electrically connected to the detection system.

[0013] The outer shell protects the vibration measuring device and transmits the vibration of the electric push rod when it is working to the vibration measuring device. When the vibration is transmitted to the vibration measuring device, the permanent magnet will shake due to its own inertia, and the elastic force of the spring can limit the shaking of the permanent magnet, and convert the vibration into the up and down movement of the permanent magnet in the transmission chamber. According to the electromagnetic induction phenomenon, the movement of the permanent magnet can be converted into a measurable current through the coil wound around the outside of the transmission chamber. The greater the vibration, the greater the current generated by the coil. The detection system can analyze the current to determine whether the electric push rod is qualified.

[0014] As shown in the figure, the reflux assembly includes a second guide rail, a third guide rail, an upper base plate, and a lower base plate. The second guide rail is fastened to the lower base plate, the third guide rail is fastened to the upper base plate, the second guide rail and the third guide rail are arranged vertically in space, the upper base plate is slidably connected to the second guide rail, and the third guide rail is on the same horizontal plane as the first guide rail.

[0015] During testing: the tooling assembly is slidably connected to the third guide rail.

[0016] By arranging a third guide rail on the upper base plate, the size of the third guide rail is the same as that of the first guide rail, and the tooling assembly can directly slide from a group of first guide rails onto the third guide rail. Then, the upper base plate slides on the second guide rail to drive the tooling assembly to another group of first guide rails, thereby completing the transfer of the tooling assembly, realizing the detection cycle, and improving work efficiency.

[0017] Furthermore, the test bench assembly includes a frame, an actuator, a tension and pressure sensor, a second fixed seat, a clamping seat, and a sliding block. The frame is tightly connected to the base, the actuator is tightly connected to the frame, the tension and pressure sensor is tightly connected to the second fixed seat, the clamping seat is tightly connected to the tension and pressure sensor, the tension and pressure sensor is located between the second fixed seat and the clamping seat, the sliding block is slidably connected to the actuator, the clamping seat is tightly connected to the sliding block, the tension and pressure sensor is electrically connected to the detection system, and the electric push rod is tightly connected to the second fixed seat.

[0018] The frame is fixed on the base to provide stable support during detection. After the tooling assembly transports the electric push rod to the position of the test bench assembly, the upper end of the electric push rod is fixed to the second fixed seat through the pin shaft, and the clamping seat is driven to move by the sliding block, thereby driving the electric push rod to move to a height suitable for detection. The clamping seat is used to fix the pull-pressure sensor on the second fixed seat. The actuator can adjust the load during the test. When the electric push rod is energized, it pushes the second fixed seat to move upward, thereby driving the sliding block to slide on the actuator. The load of the actuator will feed back a repulsive force to the pull-pressure sensor, which is the thrust of the electric push rod. The pull-pressure sensor transmits the detected signal to the detection system for analysis to determine whether the thrust of the electric push rod is qualified.

[0019] Furthermore, the actuator includes a small air pump, a protective shell, a friction plate, and a moving rod. The small air pump is firmly connected to the frame, the protective shell is firmly connected to the frame, the sliding block is slidably connected to the protective shell, a sliding cavity is provided in the protective shell, the friction plate is slidably connected to the sliding cavity, the telescopic end of the moving rod is firmly connected to the friction plate, the fixed end of the moving rod is firmly connected to the protective shell, the small air pump is connected to the sliding cavity, and the small air pump is electrically connected to the detection system;

[0020] During detection: the friction plate contacts the sliding block.

[0021] The actuator is used to adjust the load size during the test to adapt to different types of push rod tests. During the test, the small air pump is started to inflate the sliding cavity in the protective shell to increase the pressure in the sliding cavity. Under the action of the internal and external pressure difference, the friction plate is subjected to a thrust toward the sliding block. The moving rod guides the friction plate, and then presses the friction plate against the surface of the sliding block. In this way, when the sliding block moves, it will be subject to the friction force brought by the friction plate. This friction force hinders the movement of the sliding block and is then converted into the load during the test. The friction force is related to the pressure. The greater the pressure, the greater the friction force. The small air pump is controlled by the detection system to adjust the pressure in the sliding cavity, and then adjust the friction force, thereby realizing the adjustability of the test load to meet the load test of different types of push rods.

[0022] Furthermore, the locking assembly includes a pushing cylinder and a locking head, the pushing cylinder is fastened to the base, and the locking head is drivingly connected to the pushing cylinder;

[0023] During testing: the locking head contacts the fixture seat.

[0024] In order to fix the tooling assembly at the detection position to prevent it from shifting during testing, after the tooling assembly is in place, the cylinder is pushed to move the locking head upward and abut against the bottom surface of the tooling seat, thereby fixing the tooling assembly.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention divides the detection equipment into four components for implementation, all components are integrated into a complete system, and the system is modularized, automated, and conveniently designed, which can greatly improve the detection efficiency and production quality of the electric push rod;

[0026] According to the electromagnetic induction phenomenon, the vibration transmitted to the permanent magnet by the electric push rod during operation can be converted into a measurable current through the coil wound on the outside of the transmission chamber. The greater the vibration, the greater the current generated by the coil, so as to realize the detection of the vibration of the electric push rod. The structure is simple and reliable.

[0027] According to the relationship between friction and pressure, the greater the pressure, the greater the friction. The detection system controls the operation of the small air pump to adjust the pressure in the sliding chamber, and then adjusts the friction between the friction plate and the sliding block, thereby realizing automatic adjustment of the test load to meet the detection of different types of electric push rods.

After the test is completed, the electric push rod is disengaged from the test bench component 2, the locking component 7 releases the tooling component 3, and the tooling component 3 drives the electric push rod to leave the detection position. The detection system 8 determines the qualified and unqualified electric push rods, and classifies and places them at the subsequent workstations. By setting two groups of first guide rails 51, the tooling component 3 can return to the detection position driven by the reflux component 4. One group of first guide rails 51 is used to move the tooling component 3, and the other group of first guide rails 51 is used to detect the electric push rod, thereby realizing the detection cycle and making the detection process more convenient.

[0042] like Figure 1 As shown, the test bench assembly 2 and the tooling assembly 3 are arranged in several groups along the direction of the first guide rail 51 .

[0043] By providing a plurality of groups of test bench components 2 and tooling components 3, the detection efficiency can be improved and the cost can be reduced.

[0044] like Figure 1 , Figure 2 As shown, the tooling assembly 3 includes a tooling seat 31, a movable module 32, a first fixed seat 33, a clamping seat 34, and a vibration measuring device 35. The tooling seat 31 is transmission connected to the movable module 32, the movable module 32 is slidingly connected to the first guide rail 51, the first fixed seat 33 is fastened to the tooling seat 31, the clamping seat 34 is fastened to the tooling seat 31, the clamping seat 34 is fastened to the tooling seat 31, the vibration measuring device 35 is fastened to the clamping seat 34, the vibration measuring device 35 is electrically connected to the detection system 8, the electric push rod is fastened to the first fixed seat 33, and the electric push rod is clamped to the clamping seat 34.

[0045] The tooling seat 31 provides an installation basis for the first fixing seat 33 and the clamping seat 34. During testing, the bottom end of the electric push rod is fixed to the first fixing seat 33 by a pin shaft, and the rod body of the electric push rod is clamped on the clamping seat 34, which plays a guiding role for the electric push rod. The moving module 32 moves, thereby driving the tooling seat 31 to move along the first guide rail 51, and driving the electric push rod to the position of the test bench assembly 2 for testing. In order to detect the vibration of the electric push rod during operation, the transmissibility of vibration is utilized. By fixing the vibration measuring device 35 on the clamping seat 34, the vibration of the electric push rod can be detected, and the signal can be transmitted to the detection system 8 for analysis to determine whether the tested electric push rod is qualified.

[0046] like Figure 2 , Figure 3 As shown, the vibration measuring device 35 includes a shell 351, a permanent magnet 352, a spring 353, and a coil 354. The shell 351 is fastened to the clamping seat 34. A transmission chamber 3511 is provided in the shell 351. The permanent magnet 352 is located in the transmission chamber 3511. The spring 353 is fastened to the shell 351. The spring 353 suspends the permanent magnet 352 in the transmission chamber 3511. The coil 354 is wound around the outside of the transmission chamber 3511, and the coil 354 is electrically connected to the detection system 8.

[0047] The outer shell 351 protects the vibration measuring device 35 and transmits the vibration of the electric push rod when it is working to the vibration measuring device 35. When the vibration is transmitted to the vibration measuring device 35, the permanent magnet 352 will shake due to its own inertia, and the elastic force of the spring 353 can limit the shaking of the permanent magnet 352, and convert the vibration into the up and down movement of the permanent magnet 352 in the transmission chamber 3511. According to the electromagnetic induction phenomenon, the movement of the permanent magnet 352 can be converted into a measurable current through the coil 354 wound around the outside of the transmission chamber 3511. The greater the vibration, the greater the current generated by the coil 354. The detection system 8 can analyze the current to determine whether the electric push rod is qualified.

[0048] like Figure 4 As shown, the reflux assembly 4 includes a second guide rail 41, a third guide rail 42, an upper base plate 43, and a lower base plate 44. The second guide rail 41 is fastened to the lower base plate 44, the third guide rail 42 is fastened to the upper base plate 43, the second guide rail 41 and the third guide rail 42 are vertically arranged in space, the upper base plate 43 is slidably connected to the second guide rail 41, and the third guide rail 42 and the first guide rail 51 are on the same horizontal plane;

[0049] During detection: the tooling assembly 3 is slidably connected to the third guide rail 42 .

[0050] By setting a third guide rail 42 on the upper base plate 43, the size of the third guide rail 42 is the same as that of the first guide rail 51, the tooling assembly 3 can directly slide from one group of first guide rails 51 to the third guide rail 42, and then the upper base plate 43 slides on the second guide rail 41 to drive the tooling assembly 3 to another group of first guide rails 51, thereby completing the transfer of the tooling assembly 3, realizing the detection cycle, and improving work efficiency.

[0051] like Figure 5 , Figure 6 As shown, the test bench assembly 2 includes a frame 21, an actuator 22, a tension and pressure sensor 23, a second fixed seat 24, a clamping seat 25, and a sliding block 26. The frame 21 is tightly connected to the base 1, the actuator 22 is tightly connected to the frame 21, the tension and pressure sensor 23 is tightly connected to the second fixed seat 24, the clamping seat 25 is tightly connected to the tension and pressure sensor 23, the tension and pressure sensor 23 is located between the second fixed seat 24 and the clamping seat 25, the sliding block 26 is slidably connected to the actuator 22, the clamping seat 25 is tightly connected to the sliding block 26, the tension and pressure sensor 23 is electrically connected to the detection system 8, and the electric push rod is tightly connected to the second fixed seat 24.

[0052] The frame 21 is fixed on the base 1 to provide stable support during detection. After the tooling assembly 3 transports the electric push rod to the position of the test bench assembly 2, the upper end of the electric push rod is fixed to the second fixed seat 24 through a pin shaft, and the clamping seat 25 is driven to move by the sliding block 26, thereby driving the electric push rod to move to a height suitable for detection. The clamping seat 25 is used to fix the pull and pressure sensor 23 on the second fixed seat 24. The actuator 22 can adjust the load during the test. When the electric push rod is energized, it pushes the second fixed seat 24 to move upward, thereby driving the sliding block 26 to slide on the actuator 22. The load of the actuator 22 will feed back a repulsive force to the pull and pressure sensor 23, which is the thrust of the electric push rod. The pull and pressure sensor 23 transmits the detected signal to the detection system 8 for analysis to determine whether the thrust of the electric push rod is qualified.

[0053] like Figure 6 , Figure 7As shown, the actuator 22 includes a small air pump 221, a protective shell 222, a friction plate 223, and a moving rod 224. The small air pump 221 is fastened to the frame 21, the protective shell 222 is fastened to the frame 21, the sliding block 26 is slidably connected to the protective shell 222, a sliding cavity 2221 is provided in the protective shell 222, the friction plate 223 is slidably connected to the sliding cavity 2221, the telescopic end of the moving rod 224 is fastened to the friction plate 223, the fixed end of the moving rod 224 is fastened to the protective shell 222, the small air pump 221 is connected to the sliding cavity 2221, and the small air pump 221 is electrically connected to the detection system 8;

[0054] During detection: the friction plate 223 abuts against the sliding block 26 .

[0055] The actuator 22 is used to adjust the load size during the test to adapt to different types of push rod tests. During the test, the small air pump 221 is started to inflate the sliding chamber 2221 in the protective shell 222 to increase the pressure in the sliding chamber 2221. Under the action of the internal and external pressure difference, the friction plate 223 is subjected to a thrust toward the sliding block 26. The moving rod 224 guides the friction plate 223, thereby pressing the friction plate 223 against the surface of the sliding block 26. In this way, when the sliding block 26 moves, it will be subjected to the friction force brought by the friction plate 223. The friction force hinders the movement of the sliding block 26 and is then converted into the load during the test. The friction force is related to the pressure. The greater the pressure, the greater the friction force. By controlling the small air pump 221 through the detection system 8, the pressure in the sliding chamber 2221 can be adjusted, and then the friction force can be adjusted, thereby realizing the adjustability of the test load and meeting the load test of different types of push rods.

[0056] like Figure 2 , Figure 8 As shown, the locking assembly 7 includes a pushing cylinder 71 and a locking head 72. The pushing cylinder 71 is firmly connected to the base 1, and the locking head 72 is drivingly connected to the pushing cylinder 71.

[0057] During detection: the locking head 72 abuts against the tooling seat 31 .

[0059] The working principle of the present invention is as follows: first, the electric push rod is fixed on the tooling assembly 3, and then the tooling assembly 3 is slid along the first guide rail 51 to drive the electric push rod to the position of the test bench assembly 2, the locking assembly 7 is actuated to fix the tooling assembly 3 at the detection position, the electric push rod is fixed to the test bench assembly 2, and thrust and vibration tests are performed. According to the relationship between friction and pressure, the greater the pressure, the greater the friction. The small air pump 221 is controlled by the detection system 8 to adjust the pressure in the sliding cavity 2221, and then the friction between the friction plate 223 and the sliding block 26 is adjusted, thereby In order to achieve the adjustability of the test load, according to the electromagnetic induction phenomenon, the movement of the permanent magnet 352 can be converted into a measurable current through the coil 354 wound around the outside of the transmission chamber 3511. The greater the vibration, the greater the current generated by the coil 354. The detection system 8 can analyze the current to determine whether the vibration of the electric push rod is qualified. After the test is completed, the electric push rod is disengaged from the test bench assembly 2, the locking assembly 7 releases the tooling assembly 3, and the tooling assembly 3 drives the electric push rod to leave the detection position.
