Description

Technical Field

[0001] This utility model relates to the field of steel ball quality technology, and in particular to a portable steel ball quality testing instrument. Background Technology

[0002] Steel balls are classified into ground steel balls, forged steel balls, and cast steel balls according to their manufacturing processes. Alloy steel balls are spherical iron alloy wear-resistant bodies made by forging, spinning, rolling, and casting, with carbon, chromium, manganese, molybdenum, and other main added metal elements. They are the most important components in today's crushing industry, mining, and cement industries. In the production and processing of steel ball troughs, it is often necessary to use inspection tools to check the symmetrical quality of the steel ball troughs.

[0003] For example, patent number CN214041175U discloses a steel ball surface inspection device. The steel ball surface inspection device obtained by the above design uses the clamping mechanism of this utility model, which allows the clamping plate to rotate freely, so that the steel ball can be observed from multiple angles when it is inspected, simplifying the operation required for inspecting steel balls. With the setting of several nuts and screws, the nuts can be rotated and adjusted during inspection, so that this device can inspect steel balls of different specifications, reducing the cost of inspecting steel balls of different specifications and increasing the inspection efficiency.

[0004] For example, patent number CN219829842U discloses a steel ball groove testing fixture. Through the setting of testing blocks, when it is necessary to test the symmetry quality of the steel ball groove using the testing fixture, in order to improve the efficiency of symmetry testing and avoid tedious multiple tests of the symmetry of the steel ball groove, the steel ball groove can be placed into the positioning groove first. Then, an electric push rod is activated to drive the lifting rod to slide along the inner wall of the fixed groove. The sliding of the lifting rod, through the connection of the rotating rod, drives the testing blocks to slide synchronously along the outer wall of the support base and the inner wall of the testing groove, so that both sets of testing blocks slide into the steel ball groove simultaneously, achieving the effect of testing the symmetry of the steel ball groove. This achieves improved control and operation efficiency in testing the symmetry performance of the steel ball groove using the testing fixture.

[0005] However, most existing portable steel ball quality testing instruments perform testing at a single station, requiring frequent loading and unloading, resulting in low testing efficiency. Furthermore, when testing the rotating steel ball, the stability of the testing table is not high, which can easily lead to positional shifts due to vibration or external forces during the testing process, affecting the testing results of the steel ball. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a portable steel ball quality inspector. It solves the problems that most existing portable steel ball quality inspectors perform single-station inspections, requiring frequent loading and unloading, resulting in low inspection efficiency. Furthermore, when inspecting rotating steel balls, the stability of the inspection table is not high, which can easily lead to positional shifts due to vibration or external forces during the inspection process, affecting the steel ball inspection results.

[0007] The technical solution of this utility model is as follows: a portable steel ball quality detector, including a device base, a rotating seat rotatably connected to the center of the top of the device base, a limit frame and a limit seat respectively provided on both sides of the rotating seat, a connecting seat provided at the rear end of the limit seat, the bottom end of the connecting seat extending to the top of the device base, the limit seat being fixedly connected to the device base through the connecting seat, a placement hole opened on the top surface of the rotating seat, an indicator light provided above the placement hole, detection devices provided at both ends of the placement hole on the inner wall of the limit seat, one end of the detection device being aligned with the center of the placement hole, and limit blocks provided at both ends of the outer side of the limit seat. A limiting groove is formed on the surface of the rotating seat below the limiting block. A transmission assembly is set at the center of the two limiting blocks at the rear end of the connecting seat. The transmission assembly is used to connect the two limiting blocks to the limiting seat. The transmission assembly includes a servo motor B. The output end of the servo motor B is fixedly connected to a transmission rod B. One end of the transmission rod B is rotatably connected to a lead screw A. Both ends of the lead screw A extend to the outside of the limiting block and are rotatably connected to the limiting seat. When the servo motor B drives the transmission rod B to rotate, the transmission rod B transmits the power of the servo motor B to the lead screw A, so that the lead screw A drives the two limiting blocks to move inside the limiting seat.

[0008] Preferably, a servo motor A is fixedly connected to the bottom of the device base below the rotating seat. A transmission rod A is fixedly connected to the output end of the servo motor A. The top end of the transmission rod A extends to the bottom end of the rotating seat. When the servo motor A drives the transmission rod A to rotate, the servo motor A, in conjunction with the transmission rod A, drives the rotating seat to rotate on the top surface of the device base.

[0009] Preferably, both the inner walls of the limiting frame and the limiting seat are provided with guide grooves, and the two ends of the rotating seat are engaged in the inner side of the guide grooves. When the rotating seat moves, the rotating seat rotates inside the guide grooves.

[0010] Preferably, a control panel is fixedly connected to one side of the connecting base. The control panel is electrically connected to the detection device, indicator lights, servo motor A and servo motor B. The detection device, indicator lights, servo motor A and servo motor B can be controlled by the control panel. The indicator lights include red / green lights. The detection device has a built-in infrared detection camera and a ring LED lighting source. When the rotating base rotates, the two ends of the steel ball can be detected by the detection device.

[0011] Preferably, there are eight storage holes, and the number of indicator lights is the same as the number of storage holes, with each indicator light corresponding to a storage hole.

[0012] Preferably, bevel gears are provided at one end of the transmission rod B and at the center of the lead screw A. When the servo motor B drives the transmission rod B to rotate, the transmission rod B drives the lead screw A to rotate through the bevel gears.

[0013] Preferably, lead screw A is a double-threaded lead screw with symmetrical threads at both ends. When lead screw A rotates, it drives two limiting blocks to move relative to each other. One end of the limiting block is consistent with the shape of the limiting groove. When the limiting block moves, one end of the limiting block is inserted into the inner side of the limiting groove.

[0014] The beneficial effects of this utility model are:

[0015] This portable steel ball quality inspector uses a servo motor B to drive a lead screw A, which in turn drives two limit blocks to simultaneously insert into the limit grooves on the surface of the rotating seat. This achieves rigid mechanical locking of the rotating seat, effectively preventing positional displacement caused by vibration or external force during the inspection process, thus improving the accuracy and repeatability of the inspection device. By scanning both ends of the steel ball, the device can accurately identify minute surface defects. It also features eight placement holes, each corresponding to a red / green indicator light, displaying the inspection results in real time (green light indicates pass, red light indicates fail). Operators can quickly determine the quality status of the steel ball without professional training, greatly improving operational convenience and on-site efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides an embodiment: a portable steel ball quality detector, including a device base 1, a rotating seat 7 rotatably connected to the center of the top of the device base 1, a limit frame 13 and a limit seat 4 respectively provided on both sides of the rotating seat 7, a connecting seat 2 provided at the rear end of the limit seat 4, the bottom end of the connecting seat 2 extending to the top of the device base 1, the limit seat 4 being fixedly connected to the device base 1 through the connecting seat 2, a placement hole 8 is provided on the top surface of the rotating seat 7, an indicator light 9 is provided above the placement hole 8, a detection device 5 is provided at both ends of the placement hole 8 on the inner wall of the limit seat 4, one end of the detection device 5 is aligned with the center of the placement hole 8, and a limit block 6 is provided at both ends of the outer side of the limit seat 4. A limiting groove 10 is formed on the surface of the rotating seat 7 below. A transmission component is set at the center of the two limiting blocks 6 at the rear end of the connecting seat 2. The transmission component is used to connect the two limiting blocks 6 with the limiting seat 4. The transmission component includes a servo motor B14. The output end of the servo motor B14 is fixedly connected to a transmission rod B16. One end of the transmission rod B16 is rotatably connected to a lead screw A17. Both ends of the lead screw A17 extend to the outside of the limiting blocks 6 and are rotatably connected to the limiting seat 4. When the servo motor B14 drives the transmission rod B16 to rotate, the transmission rod B16 transmits the power of the servo motor B14 to the lead screw A17, so that the lead screw A17 drives the two limiting blocks 6 to move inside the limiting seat 4.

[0023] Please see Figures 1-2 In this embodiment, a servo motor A11 is fixedly connected to the bottom of the device base 1 below the rotating seat 7. A transmission rod A12 is fixedly connected to the output end of the servo motor A11. The top end of the transmission rod A12 extends to the bottom end of the rotating seat 7. When the servo motor A11 drives the transmission rod A12 to rotate, the servo motor A11 and the transmission rod A12 drive the rotating seat 7 to rotate on the top surface of the device base 1. The inner walls of the limiting frame 13 and the limiting seat 4 are both provided with guide grooves 15. The two ends of the rotating seat 7 are inserted into the inner side of the guide grooves 15. When the rotating seat 7 moves, the rotating seat 7 rotates inside the guide grooves 15.

[0024] Please see Figures 3-4In this embodiment, a control panel 3 is fixedly connected to one side of the connecting base 2. The control panel 3 is electrically connected to the detection device 5, indicator lights 9, servo motor A11, and servo motor B14. The control panel 3 can control the detection device 5, indicator lights 9, servo motor A11, and servo motor B14 respectively. The indicator lights 9 include red / green lights. The detection device 5 has a built-in infrared detection camera and a ring LED illumination source. When the rotating base 7 rotates, the two ends of the steel ball can be detected by the detection device 5. There are eight placement holes 8, and the number of indicator lights 9 is the same as the number of placement holes 8. Indicator light 9 corresponds one-to-one with storage hole 8. Bevel gear 18 is provided at one end of transmission rod B16 and at the center of lead screw A17. When servo motor B14 drives transmission rod B16 to rotate, transmission rod B16 drives lead screw A17 to rotate through bevel gear 18. Lead screw A17 is a double-threaded lead screw, and the threads at both ends of lead screw A17 are symmetrical. When lead screw A17 rotates, lead screw A17 drives two limit blocks 6 to move relative to each other. One end of limit block 6 is consistent with the shape of limit groove 10. When limit block 6 moves, one end of limit block 6 is inserted into the inner side of limit groove 10.

[0025] During operation, the device is placed in a suitable position, the power is turned on, and the device is started. The steel ball to be tested is then placed into the placement hole 8 on the top surface of the rotating seat 7. The servo motor A11, in conjunction with the transmission rod A12, drives the rotating seat 7 to rotate. There are eight placement holes 8, each corresponding to a testing station. The servo motor A11 drives the rotating seat 7 to rotate precisely within the guide groove 15 between the limit frame 13 and the limit seat 4, achieving multi-ball cyclic testing and improving testing efficiency. Furthermore, the built-in infrared detection camera in the detection device 5, aligned with the center of the placement hole 8, can perform imaging analysis on both ends of the steel ball when it is stationary, identifying the surface... Surface defects (such as scratches, cracks, pits, oxidation, etc.) are centrally controlled by the control panel 3. Each placement hole 8 is equipped with an independent red / green indicator light 9 to display the test results of the steel ball at that station in real time (green light: qualified; red light: unqualified). The operation is intuitive and convenient. Before the detection device 5 detects, when the servo motor B14 drives the transmission rod B16 to rotate, the transmission rod B16 transmits the power of the servo motor B14 to the lead screw A17, so that the lead screw A17 drives the two limit blocks 6 to be locked into the inner side of the limit groove 10 on the top surface of the rotating seat 7, thereby locking the position of the rotating seat 7 and improving the stability of the device during detection.

[0026] Compared to the prior art document CN214041175U, the steel ball surface inspection device, obtained through the above design, utilizes the clamping mechanism of this invention. This allows the clamping plate to rotate freely, enabling observation from multiple angles during steel ball inspection, simplifying the required operations. The inclusion of several nuts and screws allows for adjustment during inspection, enabling the device to inspect steel balls of different specifications, reducing the cost of inspecting different specifications, and increasing inspection efficiency. Furthermore, compared to CN219829842U, a steel ball groove inspection fixture, when inspecting the steel ball groove using this fixture, improves the inspection of the steel ball groove. The control operation for the symmetrical performance testing of the ball groove is achieved by using a servo motor B to drive the lead screw A to synchronously insert the limit blocks on both sides into the limit grooves on the surface of the rotating seat, thus realizing the rigid mechanical locking of the rotating seat. This effectively prevents positional displacement caused by vibration or external force during the testing process, improving the accuracy and repeatability of the testing device. By scanning the two ends of the steel ball with the testing device, minute surface defects can be accurately identified. Furthermore, there are eight placement holes, each corresponding to a red / green indicator light, which displays the test results in real time (green light indicates pass, red light indicates fail). Operators can quickly judge the quality status of the steel ball without professional training, greatly improving the ease of operation and on-site efficiency.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
