Description

Technical Field

[0001] The invention relates to the field of sports goods processing, and more specifically to a sports exercise barbell processing device. Background Art

[0002] Barbell is a kind of fitness training equipment, also used for weightlifting. Barbell exercise is a kind of weight training, which uses barbell training equipment to improve muscle strength. Barbell is mainly composed of barbell plates and barbell rods.

[0003] In the process of drilling holes in the existing sports barbell plates, the barbell plates are prone to displacement, which affects the drilling process and causes the overall quality of the barbell to decline. In view of this technical problem, the prior art has also proposed some solutions. For example, the Chinese utility model patent with the announcement number of CN213858043U proposes a new type of sports goods accessories processing device. The device sets a clamping block, a movable block, a sliding column and a protruding column, so that the groove at the bottom of the barbell plate cooperates with the protruding column, fixes the barbell plate above the sliding column, moves the movable block toward each other, and the movable block drives the clamping block to move toward each other, thereby fixing the barbell plate tightly. This can ensure that the barbell plate will not be offset during the drilling process;

[0004] However, in the actual barbell plate drilling process, the above method is used to fix the barbell plates, and the steps are cumbersome and inefficient, and manual loading and unloading of the barbell plates is required. The degree of automation is low, the manual labor intensity is high, and the device is only suitable for small-scale production, but not for large-scale automated assembly line production, resulting in a limited scope of application. Summary of the invention

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide a sports exercise barbell processing device.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0011] Furthermore, the protective component includes a rotating shaft that passes through the fixed frame and is fixedly connected to the locking gear, one end of the rotating shaft is fixedly connected to the No. 1 bevel gear, one side of the No. 1 bevel gear is meshingly connected to the No. 2 bevel gear, the upper end of the No. 2 bevel gear is fixedly connected to the screw, and the upper end of the screw extends through the upper end of the shell, the top end of the screw is rotatably connected to the vertical support frame, and the lower end of the vertical support frame is fixedly connected to the shell; the outer cylindrical surface of the screw is slidably connected to the ball nut seat, and one side of the ball nut seat is fixedly connected to the connecting rod, and one end of the connecting rod is fixedly connected to the protective cover.

[0012] Furthermore, the number of teeth of the first bevel gear is ten to twenty times the number of teeth of the second bevel gear.

[0013] Furthermore, when the No. 1 electromagnet on the deadweight locking assembly is in close contact with the barbell plate, the protective cover is pressed against the upper surface of the barbell plate and isolates the two No. 1 electromagnets outside the protective cover to prevent the drilling coolant from splashing on the No. 1 electromagnet.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present application sets up a deadweight locking assembly, which can automatically lock and fix the barbell plates by utilizing the weight of the barbell plates themselves. Compared with the prior art methods for fixing barbell plates, the fixing steps of the present application are simpler and more efficient, and no manual loading and unloading of the barbell plates is required. The degree of automation is high and no manual intervention is required, making the present application more suitable for large-scale automated assembly line production and having a wider scope of application.

[0020] (2) The present application sets a protective component. When the self-weight locking component is working, the protective cover can be synchronously moved down to close to the surface of the barbell plate and isolated on the inner side of the two No. 1 electromagnets. This can prevent the drilling coolant from splashing on the two No. 1 electromagnets, causing the drilling metal powder mixed with the drilling coolant to solidify on the No. 1 electromagnet after drying, thus affecting the adsorption effect. This ensures the normal operation of the self-weight locking component.

[0021] (3) By setting up a stable supporting component, when working normally, the upper arc plate and the lower arc plate on the stable supporting component are respectively inserted into the switching support grooves provided on the upper tray and the lower tray to support the upper tray and the lower tray. When it is necessary to punch a barbell plate with a larger diameter, the single chip microcomputer controls the motor to drive the rotating rod body to rotate, and then drives the different lower arc plates to rotate through the rotating rod, and rotates the supporting spring with a suitable stiffness coefficient to between the upper tray and the lower tray for supporting. Therefore, when processing a barbell plate with a larger diameter and heavier weight, it can still provide a stable supporting effect, so that the supporting spring can be slowly compressed, thereby ensuring the stability of the barbell plate during the downward movement and improving the punching accuracy.

[0043] See also Figures 1 to 10 A sports exercise barbell processing device comprises a shell 1 and a front conveyor belt 2 and a rear conveyor belt 5 arranged on the left and right sides of the shell 1; one side of the upper surface of the shell 1 is fixedly connected to an upper mounting platform 4, and a drill bit 7 is arranged on the lower surface of the top of the upper mounting platform 4, and an industrial camera 8 is arranged near the drill bit 7 on the lower surface of the top of the upper mounting platform 4, and a groove body is opened on the upper surface of the shell 1, and a barbell plate limiting component is arranged inside the groove body;

[0044] The barbell plate limiting assembly includes a middle partition 10 fixedly mounted on the inner wall of the shell 1, and the lower surface of the middle partition 10 is fixedly connected to the coolant discharge pipe 11; the upper surface of the middle partition 10 is fixedly connected to a lower tray 17, and the upper surface of the lower tray 17 is fixedly connected to a limiting cylinder 15, the top of the limiting cylinder 15 is fixedly connected to an insulating bellows 13, and the upper end of the insulating bellows 13 is fixedly connected to an upper tray 12; a positive electrode sheet 14 is also provided at the lower end of the upper tray 12, and a negative electrode sheet 16 is embedded at the upper end of the limiting cylinder 15; a feeding assembly 18 for feeding the barbell plates is provided on the upper surface of the lower tray 17, located inside the limiting cylinder 15; two groups of self-weight locking assemblies 6 for fixing the barbell plates are also symmetrically provided on both sides of the upper surface of the lower tray 17.

[0045] like Figure 3 , Figure 4 and Figure 6 As shown, the self-weight locking assembly 6 includes a fixing frame 63 fixedly connected to the upper surface of the lower tray 17, the fixing frame 63 is rotatably connected to the locking gear 62 in the middle, one side of the locking gear 62 is fixedly connected to a U-shaped rod 66, one end of the U-shaped rod 66 is provided with a No. 1 electromagnet 65, the end of the U-shaped rod 66 away from the locking gear 62 is fixedly connected to a return spring 61, and the lower end of the return spring 61 is fixedly connected to the middle partition 10; the lower end side of the upper tray 12 is also fixedly connected to a rack 64, and the rack 64 is meshingly connected to the locking gear 62, and one group of the self-weight locking assemblies 6 is also provided with a protective assembly for protecting the No. 1 electromagnet 65.

[0046] like Figure 7 As shown, a center alignment component 3 is also provided on the upper surface of the shell 1, and the center alignment component 3 includes a longitudinal slide rail 31 fixedly connected to one side of the upper surface of the shell 1, and the longitudinal slide rail 31 is slidably connected to a vertical rod 32. A transverse slide rail 33 is provided on the upper end of the vertical rod 32, and the lower end of the transverse slide rail 33 is slidably connected to a downward telescopic rod 34, and the lower end of the downward telescopic rod 34 is fixedly connected to a second electromagnet 35.

[0047] When the barbell plate is being drilled, first, the center alignment component 3 is used to cooperate with the industrial camera 8 to move the barbell plate transmitted by the front conveyor belt 2 to the middle position of the upper tray 12. When the center alignment component 3 is working, the single chip machine set in the device uses the industrial camera 8 to detect the current position of the barbell plate, and then controls the horizontal slide rail 33 to work, driving the downward telescopic rod 34 and the second electromagnet 35 to move to just above the barbell plate, and then controls the downward telescopic rod 34 to extend, driving the second electromagnet 35 close to the upper surface of the barbell plate, and then controls the second electromagnet 35 to be energized to generate a magnetic field to adsorb the barbell plate. After the adsorption is completed, the downward telescopic rod 34 is shortened, and the longitudinal slide rail 31 is used to drive the downward telescopic rod 34 and the barbell plate to move to just above the upper tray 12. After reaching the predetermined position, the single chip machine controls the downward telescopic rod 34 to extend, and the barbell plate is placed in the center position of the upper tray 12, and then the second electromagnet 35 is powered off, the magnetic field disappears, the adsorption and fixation of the barbell plate are released, and the center alignment component 3 is reset;

[0048] After placement is completed, due to the large weight of the barbell itself, the upper tray 12 will be pressed downward, and at the same time, the insulating bellows 13 will cooperate to shrink. After the upper tray 12 moves down a short distance, the rack 64 fixed to the bottom of the upper tray 12 begins to mesh with the locking gear 62, driving the locking gear 62 to rotate. When the locking gear 62 rotates, it will drive the first electromagnet 65 to rotate around the center position of the locking gear 62 through the U-shaped rod 66. At the same time, the reset spring 61 is stretched to accumulate elastic potential energy. When the upper tray 12 moves down to a close position, the When the limit cylinder 15 is at the upper end, the U-shaped rod 66 just drives the No. 1 electromagnet 65 to be placed close to the upper surface of the barbell plate placed on the upper tray 12. At the same time, the positive electrode plate 14 also contacts the negative electrode plate 16, and the circuit is turned on, so that the signal generator connected in series with the positive electrode plate 14 and the negative electrode plate 16 sends a signal to the single-chip microcomputer, so that the single-chip microcomputer detects the current state of the device and starts the No. 1 electromagnet 65 to generate a magnetic field, so as to adsorb and fix the barbell plate to prevent it from rotating and deviating during the drilling process, thereby realizing automatic and convenient fixation of the barbell plate;

[0049] After the barbell plate is fixed, the single chip microcomputer controls the drill bit 7 to move downward until it contacts the center position of the upper surface of the barbell plate, and then the drill bit 7 starts to work to drill the barbell plate. At the same time, the coolant nozzle arranged on the drill bit 7 synchronously sprays coolant to cool the drill bit 7. The coolant flows into the coolant discharge pipe 11 through the through holes arranged on the upper tray 12, the insulating bellows 13, the limiting cylinder 15, the lower tray 17 and the middle partition 10 and is discharged;

[0050] After the drilling is completed, the blanking assembly 18 works to push out the barbell plate. During the ejection process, the single-chip microcomputer first controls the No. 1 electromagnet 65 to cut off the power. As the blanking assembly 18 pushes up the barbell plate, due to the absence of the gravity pressure of the barbell plate, under the action of the contraction potential energy of the reset spring 61, the self-weight locking assembly 6 begins to reset, preparing for the next work. The ejected barbell plate is transmitted to the next process via the rear conveyor belt 5.

[0051] The present application sets up a deadweight locking component 6, which can utilize the gravity of the barbell plate itself to automatically lock and fix the barbell plate. Compared with the prior art method of fixing the barbell plate, the fixing steps of the present application are simpler and more efficient, and there is no need for manual loading and unloading of the barbell plate. The degree of automation is high and no manual intervention is required, making the present application more suitable for large-scale automated assembly line production and having a wider range of applications.

[0052] like Figure 8 As shown, the protective component includes a rotating shaft 67 that passes through the fixed frame 63 and is fixedly connected to the locking gear 62, one end of the rotating shaft 67 is fixedly connected to the No. 1 bevel gear 68, one side of the No. 1 bevel gear 68 is meshedly connected with the No. 2 bevel gear 69, the upper end of the No. 2 bevel gear 69 is fixedly connected to the lead screw 610, and the upper end of the lead screw 610 extends through the upper end of the shell 1, the top of the lead screw 610 is rotatably connected to the vertical support frame 611, and the lower end of the vertical support frame 611 is fixedly connected to the shell 1; the outer cylindrical surface of the lead screw 610 is slidably connected to the ball nut seat 612, and one side of the ball nut seat 612 is fixedly connected to the connecting rod 613, and one end of the connecting rod 613 is fixedly connected to the protective cover 614.

[0053] The number of teeth of the first bevel gear 68 is ten to twenty times the number of teeth of the second bevel gear 69 .

[0054] When the No. 1 electromagnet 65 on the deadweight locking assembly 6 is in close contact with the barbell plate, the protective cover 614 is pressed against the upper surface of the barbell plate and isolates the two No. 1 electromagnets 65 outside the protective cover 614 to prevent the drilling coolant from splashing on the No. 1 electromagnet 65.

[0055] When the barbell plate is placed on the upper tray 12 and the deadweight locking assembly 6 is working, it will drive the locking gear 62 to rotate, and the rotation of the locking gear 62 will drive the rotating shaft 67 fixed thereto to rotate, thereby driving the No. 1 bevel gear 68 fixedly connected to the rotating shaft 67 to rotate, and further driving the No. 2 bevel gear 69 to rotate. When the No. 2 bevel gear 69 rotates, the screw 610 follows the rotation and uses the ball nut seat 612 to drive the connecting rod 613 and the protective cover 614 to move downward synchronously. When the deadweight locking assembly 6 completes the adhesion to the barbell plate, the protective cover 614 moves downward synchronously to adhere to the surface of the barbell plate. It should be noted here that the number of teeth on the No. 1 bevel gear 68 is ten to twenty times the number of teeth on the No. 2 bevel gear 69, which can ensure a larger transmission ratio, so that when the locking gear 62 rotates more than half a circle, the screw 610 can rotate dozens of circles, thereby driving the protective cover 614 to descend a sufficiently long distance.

[0056] The present application sets a protective component, and when the self-weight locking component 6 is working, the protective cover 614 can be synchronously moved down to close to the surface of the barbell plate and isolated on the inner side of the two No. 1 electromagnets 65, which can prevent the drilling coolant from splashing on the two No. 1 electromagnets 65, so that the drilling metal powder mixed with the drilling coolant solidifies on the No. 1 electromagnet 65 after drying, affecting the adsorption effect, thereby ensuring the normal operation of the self-weight locking component 6.

[0057] like Fig. 9 As shown, two groups of stable supporting components 9 are symmetrically provided on both sides of the upper surface of the lower tray 17 at positions perpendicular to the two self-weight locking components 6 in a cross. The stable supporting components 9 include switching support grooves 19 opened on the upper tray 12 and the lower tray 17, and a motor 91 fixedly connected to the lower surface of the middle partition 10. The output shaft of the motor 91 is fixedly connected to a rotating rod body 92 that passes through the middle partition 10, and the bottom of the outer cylindrical surface of the rotating rod body 92 is annularly fixedly connected to evenly distributed rotating rods 93, one side of the rotating rod 93 is fixedly connected to a lower arc plate 94, the upper end of the lower arc plate 94 is fixedly connected to a reset telescopic rod 95, the upper end of the reset telescopic rod 95 is fixedly connected to an upper arc plate 97, and a supporting spring 96 sleeved on the outside of the reset telescopic rod 95 is also fixedly connected between the upper arc plate 97 and the lower arc plate 94.

[0058] The upper arc plate 97 and the lower arc plate 94 can always maintain support for the upper tray 12 and the lower tray 17 during the rotation switching gap.

[0059] The supporting springs 96 inside the stable supporting assembly 9 are respectively made of springs of the same length, the same material, and different thicknesses and diameters, so as to ensure that different stiffness coefficients are obtained under the condition of the same length.

[0060] During drilling, it is necessary to process barbell plates of the same thickness but different diameters. At this time, the barbell plate with a larger diameter is heavier and will instantly press down the reset spring 61, which is not only easy to damage the reset spring 61, but also easy to cause the barbell plate to deviate during the downward movement, resulting in reduced drilling accuracy.

[0061] By setting up a stable supporting component 9, during normal operation, the upper arc plate 97 and the lower arc plate 94 on the stable supporting component 9 are respectively inserted into the switching support grooves 19 provided on the upper tray 12 and the lower tray 17 to support the upper tray 12 and the lower tray 17. When it is necessary to punch holes in barbell plates with larger diameters, the single-chip microcomputer controls the motor 91 to drive the rotating rod body 92 to rotate, and then drives the different lower arc plates 94 to rotate through the rotating rod 93, and rotates the supporting spring 96 with a suitable stiffness coefficient to between the upper tray 12 and the lower tray 17 for support, so that when processing barbell plates with larger diameters and heavier weights, a stable supporting effect can still be provided, so that the supporting spring 96 can be slowly compressed, thereby ensuring the stability of the barbell plates during the downward movement and improving the punching accuracy.

[0062] like Fig.10 As shown, the unloading assembly 18 includes two multi-stage telescopic rods 181 symmetrically arranged on the upper surface of the lower tray 17, and the upper ends of the two multi-stage telescopic rods 181 are hinged to the ejecting plate 182.

[0063] When the unloading assembly 18 is working, the single chip microcomputer first controls the two multi-stage telescopic rods 181 to extend synchronously, so that the barbell plate is first moved to the outside of the housing 1, and then controls the single multi-stage telescopic rod 181 on the left to extend, and cooperates with the multi-stage telescopic rod 181 on the right to remain stationary, so that the ejecting plate 182 is tilted, and then the barbell plate placed on the ejecting plate 182 is tilted, and slides down to the rear conveyor belt 5 under the action of gravity to enter the next process;

[0064] It should be noted that Fig.10 It can be seen that the top plate 182 is a circular plate with a through hole in the middle, and the through hole can ensure that the coolant and the drilling metal powder are smoothly discharged into the coolant discharge pipe 11 during the drilling process, so as to flow to the outside for subsequent processing; in addition, the specific structure of the upper tray 12 is as follows Figure 8 As shown, it is in the shape of a disk, and switching support grooves 19 are symmetrically provided on both sides of the lower surface. A through groove is provided in the middle position for the coolant and drilling metal powder to fall, and the diameter of the through groove is larger than the diameter of the ejector plate 182. When the unloading assembly 18 is working, the multi-stage telescopic rod 181 is extended to drive the ejector plate 182 to extend from the above-mentioned through groove, thereby lifting the barbell plate placed on the upper tray 12 to the outside of the shell 1.

[0065] Method of use: When the present invention is used, first, the barbell plate transmitted by the front conveyor belt 2 is moved to the middle position of the upper tray 12 by using the center alignment component 3 in conjunction with the industrial camera 8;

[0066] After placement is completed, due to the large weight of the barbell itself, the upper tray 12 will be pressed downward, and at the same time, the insulating bellows 13 will cooperate to shrink. After the upper tray 12 moves down a short distance, the rack 64 fixed to the bottom of the upper tray 12 begins to mesh with the locking gear 62, driving the locking gear 62 to rotate. When the locking gear 62 rotates, it will drive the first electromagnet 65 to rotate around the center position of the locking gear 62 through the U-shaped rod 66. At the same time, the reset spring 61 is stretched to accumulate elastic potential energy. When the upper tray 12 moves down to a close position, the When the limit cylinder 15 is at the upper end, the U-shaped rod 66 just drives the No. 1 electromagnet 65 to be placed close to the upper surface of the barbell plate placed on the upper tray 12. At the same time, the positive electrode plate 14 also contacts the negative electrode plate 16, and the circuit is turned on, so that the signal generator connected in series with the positive electrode plate 14 and the negative electrode plate 16 sends a signal to the single-chip microcomputer, so that the single-chip microcomputer detects the current state of the device and starts the No. 1 electromagnet 65 to generate a magnetic field, so as to adsorb and fix the barbell plate to prevent it from rotating and deviating during the drilling process, thereby realizing automatic and convenient fixation of the barbell plate;

[0067] After the barbell plate is fixed, the single chip microcomputer controls the drill bit 7 to move downward until it contacts the center position of the upper surface of the barbell plate, and then the drill bit 7 starts to work to drill the barbell plate. At the same time, the coolant nozzle arranged on the drill bit 7 synchronously sprays coolant to cool the drill bit 7. The coolant flows into the coolant discharge pipe 11 through the through holes arranged on the upper tray 12, the insulating bellows 13, the limiting cylinder 15, the lower tray 17 and the middle partition 10 and is discharged;

[0068] After the drilling is completed, the blanking assembly 18 works to push out the barbell plate. During the ejection process, the single-chip microcomputer first controls the No. 1 electromagnet 65 to cut off the power. As the blanking assembly 18 pushes up the barbell plate, due to the absence of the gravity pressure of the barbell plate, under the action of the contraction potential energy of the reset spring 61, the self-weight locking assembly 6 begins to reset, preparing for the next work. The ejected barbell plate is transmitted to the next process via the rear conveyor belt 5.

[0069] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
