Description

Technical Field

[0001] The utility model relates to the technical field of automatic press-fitting machines, in particular to an automatic press-fitting machine. Background Art

[0002] An automatic press-fitting machine is a device used to compress and fit materials during the production process. It is widely used in manufacturing industries such as pharmaceuticals, food, chemicals, and electronics to compress materials such as powders and granules into shapes. Its primary functions include placing the material into a press-fitting die, applying pressure to form the material into the desired shape, and then removing it after forming.

[0003] When the existing automatic press-fitting machine adjusts the press cylinder, there will be a moving gap after the press cylinder is adjusted, which will cause deviation during operation. For example, the Chinese patent discloses "an automatic press-fitting machine", and its application number is "CN202122671645.6". It uses a handle in the control structure to drive the double-headed stud to rotate, and then drives the vertical plate to move inward. The moving vertical plate drives the slide plate to separate from the inner side of the concave plate, and then moves the concave plate forward on the outer wall of the support plate to achieve press cylinder adjustment. Subsequently, the above operation is reversed, and the slide plate is moved outward to press the concave plate tightly to complete the fixation of the press cylinder, ensuring the stability of the concave plate, preventing work deviation, ensuring consistency, and reducing the difficulty of press-fitting. However, it often deviates during the movement and cannot move to the specified position quickly. At the same time, the slide groove slides more sensitively. Utility Model Content

[0004] In response to the deficiencies in the prior art, the present invention provides an automatic press-fitting machine. Through the cooperation of a spring, a second telescopic rod, a fixed block, a base, a gear, and a rack, the first telescopic rod and the spring provide necessary elastic support to ensure that the fixed block always maintains an appropriate position during the adjustment process. Since the elastic forces of the springs on both sides are equal, the connecting rod can always quickly restore its position and align with the press-fitting machine; the second telescopic rod further reduces the moving space of the connecting rod, thereby effectively preventing the problem of moving gaps after the pressing cylinder is adjusted, ensuring stability and accuracy during operation. The adjustment accuracy of the gear, rack, and rotating shaft is higher, ensuring the accuracy of the pressing cylinder during operation, thereby improving stability and press-fitting accuracy during operation and reducing the difficulty of press-fitting.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic press-fitting machine, comprising a workbench, the upper surface of which is fixedly connected to the press-fitting machine body; a connecting rod is provided at the bottom of the workbench, a pressing cylinder is fixedly connected to the upper surface of the connecting rod, a base is provided on the connecting rod, a fixed block is slidably connected to the inside of the base, a first telescopic rod and a spring are provided inside the base, the springs on both sides have equal elastic force, a second telescopic rod is fixedly connected to the outer surface of the base, a rotating shaft is provided at the bottom of the workbench, a gear is provided on the rotating shaft, and a rack is meshed and connected to the inside of the gear. Through the above device, through the cooperation of the spring, the second telescopic rod, the fixed block, the base, the gear, and the rack, the moving gap of the pressing cylinder is significantly reduced, and the offset phenomenon during work is prevented, thereby improving the accuracy and stability of press-fitting, reducing the difficulty of operation, and improving work efficiency.

[0006] Furthermore, the workbench is internally provided with a second slide rail and a first slide rail, and the connecting rod is slidably connected to the second slide rail and the first slide rail. The second slide rail is located at the inner bottom of the workbench, and the first slide rail is located at the inner top of the workbench. Through the above device, the second slide rail and the first slide rail further stabilize the position of the connecting rod, reducing the movement gap of the pressing cylinder.

[0007] Furthermore, the pressing cylinder is in contact with the upper surface of the workbench and is located directly below the press fitting machine body. Through the above device, the stability of the pressing cylinder is ensured by making the pressing cylinder in contact with the workbench surface, and the increase in press fitting difficulty caused by position deviation is avoided.

[0008] Furthermore, there are two fixing blocks, one of which is provided with a semicircular groove, which fits in with the connecting rod. Through the above device, the semicircular groove design of the fixing block ensures the stable positioning of the connecting rod and reduces the movement gap.

[0009] Furthermore, the first telescopic rod is fixedly connected to the outer surface of the fixed block, and the spring is located outside the first telescopic rod. Through the above device, the cooperation between the telescopic rod and the spring increases the stability of the fixed block, preventing the pressure cylinder from deflecting during operation, while the elastic force of the spring allows the pressure cylinder to quickly return to its original position.

[0010] Furthermore, the second telescopic rod is fixedly connected to the inner wall surface of the workbench, and the second telescopic rod is located on both sides of the connecting rod. Through the above device, the connecting rod is further fixed by the second telescopic rod to ensure the stability of the pressure cylinder after adjustment.

[0011] Furthermore, the side surface of the base is fixedly connected to two side panels, which are fixedly connected by a telescopic plate, and the rotating shaft is fixedly connected to the outer surface of the telescopic plate. Through the above device, the connecting rod can be easily moved through the side panels and the telescopic plate, and the fixing block can also be easily removed.

[0012] Furthermore, a third slide rail is provided on the side wall of the workbench, the rotating shaft is slidably connected to the interior of the third slide rail, a knob is fixedly connected to the other end of the rotating shaft, and the rack is located on the inner bottom surface of the workbench. Through the above device, the design of the third slide rail and the knob facilitates the adjustment of the rotating shaft, ensuring the accuracy of the pressing cylinder during operation.

[0013] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0014] The automatic press-fitting machine, through the cooperation of the spring, the second telescopic rod, the fixed block, the base, the gear and the rack, the first telescopic rod and the spring provide the necessary elastic support to ensure that the fixed block always maintains the appropriate position during the adjustment process. Since the elastic force of the springs on both sides is equal, the connecting rod can always quickly restore its position and align with the press-fitting machine; the second telescopic rod further reduces the moving space of the connecting rod, thereby effectively preventing the problem of moving gap after the pressing cylinder is adjusted, ensuring stability and accuracy during operation, the adjustment accuracy of the gear and rack, and the rotating shaft is higher, ensuring the accuracy of the pressing cylinder when working, thereby improving the stability and press-fitting accuracy during operation and reducing the difficulty of press-fitting.
