Description

Technical Field

[0001] The utility model relates to the technical field of industrial production devices, and in particular to a device mainly used for inserting axle pins into industrial products, such as earphone storage boxes and other box products. Background Art

[0002] In the field of industrial production, it is often necessary to insert a very small pin into a small hole in the product. For example, in the earplug storage box, the upper and lower covers need to be hinged together by an axle pin so that the upper and lower covers can be easily opened and closed. In traditional technology, the pinning operation is usually performed by fixture positioning and manual pressing. The main disadvantages are: first, the positioning is not accurate enough, because the irregular shape of the irregular workpiece and the space are very small. If the workpiece is not accurately introduced (positioned) at one time, two workpieces will be scrapped directly, resulting in a large defective rate and increasing the production cost of the enterprise; second, there are major safety hazards. Workers may think that they have been positioned well, one hand is still holding the workpiece, and the other hand is manually pressed into the fixture, which is easy to cause safety accidents; third, the introduction (positioning) speed is slow, resulting in low production efficiency. Although some people have invented some equipment that can perform pinning operations, the existing equipment is relatively complex in structure, involves many parts, has high cost, and is more prone to failure. Utility Model Content

[0003] The utility model aims at the shortcomings of the prior art and provides an automatic pin threading processing equipment with simpler structure, fewer parts, lower cost and higher pin threading efficiency, which can be mainly used for inserting shaft pins for box products such as earphone (earplug) boxes.

[0005] Furthermore, the downward pressure cylinder is vertically mounted on a mounting frame, the upper die is mounted on the bottom surface of an upper die seat, and the upper die seat is assembled and fixed to the cylinder rod of the downward pressure cylinder.

[0006] Furthermore, the clamping cylinder is installed below the lower die, and its cylinder rod extends horizontally forward from below the lower die to be connected and fixed to the clamping seat, and the workpiece positioning block is vertically installed on the side of the clamping seat facing the lower die.

[0007] Furthermore, the guide seat is installed on the mounting frame and is located beside the lower mold, and the pin-penetrating rod extends horizontally toward the guide seat.

[0008] Preferably, the electric control mechanism includes two starting switches, which are respectively arranged at the front part of the workbench near the left and right sides. The two starting switches adopt a double switch linkage structure. The equipment can only be started to perform the pin threading operation when both hands are pressed at the same time.

[0009] Furthermore, the electric control mechanism also includes an emergency stop switch, which is arranged on the front side of the fuselage.

[0010] Furthermore, a timer is arranged on the front of the fuselage, and the timer is connected to the electric control mechanism and is used to measure the time of the working process.

[0012] Furthermore, the electric control mechanism includes a solenoid valve, through which the operation of the pressing cylinder and the clamping cylinder is controlled.

[0013] The utility model uses a cylinder to press the axle pin toward the workpiece, and the workpiece positioning mechanism is obtained by CNC processing, so that irregular and difficult-to-position workpieces can be accurately introduced and accurately processed through the equipment, and linked pressing. Pressurization is applied while mounting to ensure perfect fit and reduce the labor intensity of workers; in addition, after the workpiece is placed in the equipment, both hands must be removed and both hands must be started at the same time to operate the equipment to ensure the safety of the workers.
