Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, and in particular to a nut pressing machine for nut processing. Background Technology

[0002] Nylon self-locking nuts are a new type of high vibration-resistant and anti-loosening fastening part that can be used in various mechanical and electrical products with temperatures ranging from -50 to 100℃. The demand for nylon self-locking nuts has increased dramatically in the fields of aviation, tanks, mining machinery, automobile transportation machinery, agricultural machinery, textile machinery, electrical products, and various other machinery. Pneumatic capping machines for nylon self-locking nuts are required in the production process.

[0003] Existing equipment, such as CN221161660U, is a pneumatic nut press for nylon self-locking nuts. The worktable body has vertical plates fixedly installed on both sides of its upper surface. A clamping and conveying assembly is installed between the two vertical plates. A U-shaped bracket is fixedly installed on one side of the top of the two vertical plates. A stamping assembly for easy pressure adjustment is installed on the U-shaped bracket. In this invention, by setting a spring in the clamping and conveying assembly, the spring's reset function drives the corresponding positioning mold to maintain the workpiece in a clamping and positioning state. Simultaneously, a stepper motor is started to convey the clamped and positioned workpiece. Furthermore, the detachable positioning mold facilitates the clamping, conveying, and adjustment of workpieces of different specifications and sizes, resulting in strong applicability and high work efficiency.

[0004] The existing technology uses belts to drive the mounting mold on both sides. However, using two sets of motors may lead to synchronization problems due to individual differences in the motors and environmental influences. Furthermore, this structure cannot reuse the mounting mold, increasing costs. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology where two motors are used and synchronization errors are easy to occur, and to propose a nut pressing machine for nut processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a nut pressing machine for nut processing, comprising a worktable, a conveyor, a U-shaped frame, a push rod, and a clamping device. The conveyor is fixedly connected to the upper surface of the worktable, the U-shaped frame is fixedly connected to the upper surface of the worktable, the push rod is mounted on the U-shaped frame, and the clamping device is disposed on the conveyor. The clamping device includes mounting holes, which are formed on the conveyor. There are multiple sets of mounting holes arranged linearly and evenly. Nuts are fixedly connected to the inner walls of the multiple sets of mounting holes. A screw is threadedly connected to the inner wall of the nut. An mounting plate is fixedly connected to the upper surface of the screw. A groove is formed on the upper surface of the mounting plate. An insert rod is slidably connected to the inner wall of the groove. An installation mold is fixedly connected to the upper surface of the insert rod.

[0007] Furthermore, the mounting plate is provided with a fixing component, which includes a sliding groove. The sliding groove is formed on the inner side wall of the groove, and there are two sets of sliding grooves arranged symmetrically.

[0008] Furthermore, a trapezoidal block one is slidably connected to the inner wall of the groove, the trapezoidal block one is in close contact with the surface of the insert rod, and a trapezoidal block two is slidably connected to the inner wall of the groove.

[0009] Furthermore, the second trapezoidal block is slidably connected to the surface of the first trapezoidal block, and a tie rod is fixedly connected to the upper surface of the second trapezoidal block, the tie rod being slidably connected to the inner wall of the mounting plate.

[0010] Furthermore, a protrusion is fixedly connected to the top of the pull rod, and a spring is sleeved on the surface of the pull rod. The two ends of the spring are fixedly connected to the trapezoidal block and the inner wall of the slide groove.

[0011] Furthermore, the inner wall of the slide is provided with a slot, and a locking block is slidably connected to the inner wall of the slot. The locking block is fixedly connected to the trapezoidal block.

[0012] Furthermore, a recessed block is slidably connected to the output end of the push rod, and a pressure cap head is fixedly connected to the lower surface of the recessed block. A limit rod is slidably connected to the inner wall of the output end of the push rod, and a limit hole is opened on the surface of the limit rod. A limit block is slidably connected to the inner wall of the limit hole, and the limit hole is slidably connected to the upper surface of the recessed block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, a clamping device is provided to facilitate the transport of installation molds of different sizes. When changing the installation mold, the protrusion pulls the pull rod, which slides the trapezoidal block two. At the same time, the trapezoidal block two compresses the spring, causing the spring to contract under force. The trapezoidal block one is then freed from the restraint of the trapezoidal block two, and the installation mold and the insertion rod are pulled. Then, the new installation mold is inserted into the groove. Subsequently, the protrusion and the pull rod are released, and the spring, freed from restraint, pushes the trapezoidal block two to slide. The trapezoidal block two pushes the trapezoidal block one to clamp the insertion rod. Then, the limiting block is pulled out, the limiting rod and the concave block are removed, and a suitable concave block with a pressure cap is replaced. By providing a clamping device, it is easy to transport installation molds of different sizes. The installation molds can be reused repeatedly, saving costs and effectively improving the practicality of the equipment. Attached Figure Description
