Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of nut-feeding machine technology, and more specifically, to an automatic nut-feeding machine. Background Technology

[0002] A nut is a fastener that is screwed onto a bolt or threaded rod to secure a fastener. It is an essential component in all manufacturing machinery. Depending on the material, nuts are classified into several types, such as carbon steel, stainless steel, and non-ferrous metals (e.g., copper). A nut-making machine is a type of mechanical equipment used to manufacture nuts. It is widely used in the production of fasteners such as nuts and bolts. Nut-making machines mainly process metal materials into standard or non-standard nuts through rotary processing, pressure processing, and other techniques.

[0003] The publication number CN218800368U discloses an automatic nut feeding machine, including a main body, a side plate on the upper right side of the main body, a slide groove on the side plate, a slider A slidably connected to the slide groove, a conveyor belt embedded on the upper side of the main body, the conveyor belt being located below the nut feeding device, a nut feeding device installed on the left side of the nut feeding device, a nut feeding device having an output end connected to a feeding port on one side, an output end of the feeding port being connected to an input end of an air pipe locking module A, an air pipe locking module A being installed on the lower right side of the nut feeding device, and a switching module being fixedly connected to the upper side of the air pipe locking module A.

[0004] The aforementioned application document describes a method where the threaded end of the workpiece to be locked by the nut is placed inside the nut, and the ventilated locking module B automatically locks it. However, this method is not effective enough in locking the workpiece with the nut, and the nut may not be fully locked, which is detrimental to subsequent production work. Therefore, it needs to be improved. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an automatic nut-locking machine, which solves the technical problem in the prior art where the nut is not fully locked and tightened.

[0006] According to one aspect, at least one embodiment of this disclosure provides an automatic nut-attaching machine, comprising: a worktable, a transmission device and an automatic assembly mechanism disposed on the top of the worktable, a support plate fixedly connected to the top of the worktable, an electric push rod fixedly mounted on one end of the support plate near the worktable, and a clamping plate fixedly connected to the output end of the electric push rod; the automatic assembly mechanism includes a support column, the bottom of the support column fixedly connected to the top of the worktable, a top plate fixedly connected to the top of the support column, a bracket fixedly connected to the bottom of the top plate, and a slide rod fixedly connected to the inner side of the bracket. A movable motor is fixedly installed on the side of the bracket. A threaded rod is rotatably connected to the inner side of the bracket. A movable seat is slidably connected to the surface of the sliding rod. A hydraulic cylinder is fixedly installed at the bottom of the movable seat. A lifting plate is fixedly connected to the output end of the hydraulic cylinder. An assembly rod is rotatably connected to the bottom of the lifting plate. A driven gear is fixedly connected to the surface of the assembly rod. A nut groove is opened at the bottom of the assembly rod. A rotating motor is fixedly installed at the top of the lifting plate. A rotating shaft is rotatably connected through the bottom of the lifting plate. A driving gear is fixedly connected to the bottom of the rotating shaft. A flushing mechanism is provided at the top of the lifting plate.

[0007] For example, in at least one embodiment of this disclosure, an automatic nut-attaching machine is provided, which further includes: two sets of clamping plates, and the bottom of both sets of clamping plates is higher than the top of the transmission device. The workpiece on the transmission device can be clamped by the two sets of clamping plates moving closer to each other.

[0008] The output shaft of the mobile motor is fixedly connected to the threaded rod, and the mobile seat is threadedly connected to the threaded rod through the built-in thread. When the mobile motor is turned on, it will drive the threaded rod to rotate through its output shaft. The rotation of the threaded rod will drive the mobile seat to move along the slide rod through the engagement of the threads.

[0009] The output shaft of the rotary motor is fixedly connected to the rotating shaft. The driving gear meshes with the driven gear. When the rotary motor is turned on, it drives the rotating shaft to rotate through its output shaft. When the driving gear rotates, it drives the driven gear to rotate.

[0010] The top of the nut groove has a through groove, which allows the screw on the workpiece to enter the assembly rod.

[0011] According to another aspect, at least one embodiment of this disclosure also provides a flushing mechanism, including a water pressure chamber and a water tank. The water pressure chamber and the water tank are both fixedly connected to the top of the lifting plate. A piston rod is slidably connected to the internal piston of the water pressure chamber. A contact plate is fixedly connected to the top of the piston rod. A compression spring is sleeved on the surface of the piston rod. A water suction pipe is passed through and fixedly connected to the side of the water pressure chamber. A water outlet pipe is passed through and fixedly connected to the front end of the water pressure chamber. A one-way valve is provided inside both the water suction pipe and the water outlet pipe.

[0012] For example, in at least one embodiment of this disclosure, an automatic nut-attaching machine is provided, which further includes: the top of the contact plate initially abuts against the bottom of the moving seat, and the contact plate leaves the bottom of the moving seat when the lifting plate drives the water pressure chamber to move downward.

[0013] In its initial state, the two ends of the compression spring are in contact with the bottom of the contact plate and the top of the water pressure chamber, and the compression spring is in a compressed state. When the contact plate leaves the bottom of the moving seat, the compression spring will rebound and drive the contact plate and piston rod to move upward relative to the water pressure chamber.

[0014] The one-way valve inside the suction pipe is designed to allow unidirectional flow into the water pressure chamber, and the end of the suction pipe away from the water pressure chamber is connected to the water tank in a fixed manner. When a negative pressure is formed inside the water pressure chamber, water will be drawn from the water tank through the suction pipe.

[0015] The one-way valve inside the water outlet pipe is unidirectionally open to the outside of the water pressure chamber, and the end of the water outlet pipe away from the water pressure chamber is close to the assembly rod. When the water in the water tank is squeezed, the water inside will be discharged to the assembly rod through the water outlet pipe.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] 1. This disclosure features an automatic assembly mechanism, which allows the moving seat to move by turning on the moving motor to rotate the threaded rod, and the lifting plate to move downward by turning on the hydraulic cylinder, thereby adjusting the distance between the assembly rod and the screw on the workpiece. When the rotating motor turns on the rotating shaft, the assembly rod is rotated by the cooperation of components such as the drive gear and the driven gear, and the internal nut is installed on the screw on the workpiece, with a better locking and fastening effect.

[0018] 2. This invention incorporates a flushing mechanism, which, after the assembly rod is used to lock and tighten the nut, and the hydraulic cylinder is activated to move the lifting plate upwards to the top to return to its original position, utilizes the cooperation of components such as the contact plate, piston rod, and water pressure chamber to draw water from the water tank through the suction pipe and discharge it onto the assembly rod through the outlet pipe. This cools the bottom of the assembly rod, facilitating the insertion of the next set of nuts by the workers. Attached Figure Description

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-6The diagram illustrates an automatic nut-attaching machine according to an embodiment of this disclosure, comprising: a workbench 1, a transmission device 2 and an automatic assembly mechanism 6 disposed on the top of the workbench 1, a support plate 3 fixedly connected to the top of the workbench 1, an electric push rod 4 fixedly mounted on one end of the support plate 3 near the workbench 1, and a clamping plate 5 fixedly connected to the output end of the electric push rod 4; the automatic assembly mechanism 6 includes a support column 61, the bottom of the support column 61 fixedly connected to the top of the workbench 1, a top plate 62 fixedly connected to the top of the support column 61, a bracket 63 fixedly connected to the bottom of the top plate 62, a slide rod 64 fixedly connected to the inner side of the bracket 63, and a [missing information - likely a component or component] fixedly mounted on the side of the bracket 63. A threaded rod 614 is rotatably connected to the inner side of the movable motor 65 and the bracket 63. A movable seat 66 is slidably connected to the surface of the slide rod 64. A hydraulic cylinder 67 is fixedly installed at the bottom of the movable seat 66. A lifting plate 68 is fixedly connected to the output end of the hydraulic cylinder 67. An assembly rod 69 is rotatably connected to the bottom of the lifting plate 68. A driven gear 610 is fixedly connected to the surface of the assembly rod 69. A nut groove 616 is opened at the bottom of the assembly rod 69. A rotating motor 611 is fixedly installed at the top of the lifting plate 68. A rotating shaft 612 is rotatably connected through the bottom of the lifting plate 68. A driving gear 613 is fixedly connected to the bottom of the rotating shaft 612. A flushing mechanism 7 is provided at the top of the lifting plate 68.

[0034] In some examples, the clamping plates 5 are configured in two sets, and the bottom of both sets of clamping plates 5 is higher than the top of the transmission device 2. The workpiece on the transmission device 2 can be clamped by moving the two sets of clamping plates 5 close to each other.

[0035] The output shaft of the mobile motor 65 is fixedly connected to the threaded rod 614. The movable seat 66 is threadedly connected to the threaded rod 614 through its internal thread. When the mobile motor 65 is turned on, it will drive the threaded rod 614 to rotate through its output shaft. The rotation of the threaded rod 614 will drive the movable seat 66 to move along the slide rod 64 through the engagement of the threads.

[0036] The output shaft of the rotating motor 611 is fixedly connected to the rotating shaft 612. The driving gear 613 meshes with the driven gear 610. When the rotating motor 611 is turned on, it will drive the rotating shaft 612 to rotate through its output shaft. When the driving gear 613 rotates, it will drive the driven gear 610 to rotate.

[0037] The top of the nut groove 616 is provided with a through groove 617, which allows the screw on the workpiece to enter the assembly rod 69.

[0038] For example, such as Figures 1-6As shown, the workpiece is placed on the conveyor device 2 for transport. The nut is inserted into the nut groove 616, and the moving motor 65 is turned on. The moving motor 65 drives the threaded rod 614 to rotate through its output shaft. The rotation of the threaded rod 614 will drive the moving seat 66 to move along the slide rod 64 through the engagement of the threads, thereby adjusting the position of the assembly rod 69. The hydraulic cylinder 67 is turned on, which drives the lifting plate 68 to descend, so that the assembly rod 69 contacts the screw. The screw enters the assembly rod 69. Then, the rotating motor 611 is turned on. The rotating motor 611 drives the rotating shaft 612 to rotate through its output shaft. The rotating shaft 612 drives the driving gear 613 to rotate. The driving gear 613 drives the driven gear 610 to rotate. The driven gear 610 drives the assembly rod 69 to rotate. The rotation of the assembly rod 69 drives the nut in the nut groove 616 to be installed onto the screw on the workpiece, and the locking and fastening effect is better.

[0039] like Figures 1-6 As shown, a flushing mechanism 7 in another embodiment of the present disclosure is illustrated, including a water pressure chamber 71 and a water tank 76. Both the water pressure chamber 71 and the water tank 76 are fixedly connected to the top of the lifting plate 68. A piston rod 72 is slidably connected to the piston inside the water pressure chamber 71. A contact plate 73 is fixedly connected to the top of the piston rod 72. A compression spring 74 is sleeved on the surface of the piston rod 72. A water suction pipe 75 is fixedly connected through the side of the water pressure chamber 71. A water outlet pipe 77 is fixedly connected through the front end of the water pressure chamber 71. Both the water suction pipe 75 and the water outlet pipe 77 are provided with one-way valves inside.

[0040] In some examples, the top of the contact plate 73 is initially in contact with the bottom of the movable seat 66, and the contact plate 73 will leave the bottom of the movable seat 66 when the lifting plate 68 moves the hydraulic chamber 71 downward.

[0041] In the initial state, the two ends of the compression spring 74 are in contact with the bottom of the contact plate 73 and the top of the water pressure chamber 71, and the compression spring 74 is in a compressed state in the initial state. When the contact plate 73 leaves the bottom of the moving seat 66, the compression spring 74 will rebound and drive the contact plate 73 and the piston rod 72 to move upward relative to the water pressure chamber 71.

[0042] The one-way valve inside the suction pipe 75 is for one-way flow into the water pressure chamber 71, and the end of the suction pipe 75 away from the water pressure chamber 71 is connected to the water tank 76 through and fixedly connected. When a negative pressure is formed inside the water pressure chamber 71, water will be drawn from the water tank 76 through the suction pipe 75.

[0043] The one-way valve inside the water outlet pipe 77 is unidirectionally open to the outside of the water pressure chamber 71, and the end of the water outlet pipe 77 away from the water pressure chamber 71 is close to the assembly rod 69. When the water in the water tank 76 is squeezed, the water in the tank will be discharged through the water outlet pipe 77 onto the assembly rod 69.

[0044] For example, such as Figures 1-6As shown, when the lifting plate 68 moves the water pressure chamber 71 downward, the contact plate 73 will leave the bottom of the moving seat 66. When the contact plate 73 leaves the bottom of the moving seat 66, the compression spring 74 will rebound and move the contact plate 73 and the piston rod 72 upward relative to the water pressure chamber 71. At this time, a negative pressure is formed in the water pressure chamber 71, which will draw water from the water tank 76 through the suction pipe 75. When the assembly rod 69 rotates and drives the nut in the nut groove 616 to be installed on the screw on the workpiece, the lifting plate 68 is raised to the top. At this time, the contact plate 73 contacts the top of the moving seat 66 again and moves downward relative to the water pressure chamber 71. The downward movement of the contact plate 73 drives the piston rod 72 to move downward. At this time, the water in the water tank 76 will be squeezed, and the water in it will be discharged to the assembly rod 69 through the water outlet pipe 77, which will cool the bottom of the assembly rod 69 and make it easier for the staff to put in the next set of nuts.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
