Description

Technical Field

[0001] The utility model relates to the field of assembly equipment, in particular to a rotary double-station cold press. Background Art

[0002] At present, many spare parts on automobiles (such as physical buttons on the dashboard) need to be assembled using a cold press. The structure of the cold press commonly used for assembly is shown in the patent publication document CN220742246U. The cold press of this structure relies on the worm gear (the figure numbers in the document are 8 and 6) for rotation, but because there is a rotating column (the figure number in the document is 9) between the turntable (the figure number in the document is 10) and the worm gear for support, the diameter of the rotating column is smaller than the turntable and the worm gear, so the structure is thick at both ends and thin in the middle. There is a problem with this structure that is thick at both ends and thin in the middle during use, that is, when the turntable located at the top is squeezed, the worm gear located at the bottom will tend to swing, and when the worm gear tends to swing, the fitting clearance between the worm gear and the worm gear will change, resulting in increased wear between the worm gear and the worm gear. Utility Model Content

[0003] In view of the above problems, the utility model proposes a rotary double-station cold press machine.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A rotary double-station cold press comprises a base and a bracket, wherein the bracket is arranged on the base, a cylinder is arranged on the bracket, a pressure plate is arranged on the cylinder rod of the cylinder, and the cold press comprises a worm wheel, a worm, a servo motor, a mounting plate and an assembly table, wherein the worm wheel is rotatably arranged on the base, the servo motor is fixedly arranged on the base, the worm is mounted on the shaft of the servo motor, the worm cooperates with the worm wheel, the mounting plate is arranged on the worm wheel, and the two end faces of the worm wheel are respectively pressed against the mounting plate and the base, and there are two assembly tables, both of which are arranged on the mounting plate.

[0006] In this cold press machine, the assembly table is used to place the workpiece, and the pressing plate is used to press the workpiece on the assembly table. Since two assembly tables are set up and the assembly tables are set on the mounting plate, the servo motor can drive the rotation of the mounting plate position with the help of the worm gear, and the rotation of the mounting plate position can realize the switching of the position between the two assembly tables, so that the pressing plate can realize continuous extrusion operation.

[0007] At the same time, in this cold press machine, the two end faces of the worm wheel are respectively pressed against the end face of the base and the mounting plate, and a plate-like structure rather than an I-shaped structure is formed between the worm wheel, the base and the mounting plate. Therefore, there is good stability between the base, the worm wheel and the mounting plate. When the mounting plate is under pressure, the worm wheel will not be lagging, which can ensure the stability of the cooperation between the worm wheel and the worm and reduce the wear between the worm wheel and the worm during use.

[0008] In summary, the two end faces of the worm wheel are respectively pressed against the end face of the base and the mounting plate, and a plate-like structure rather than an I-shaped structure is formed between the worm wheel, the base and the mounting plate. The base, the worm wheel and the mounting plate have good stability. When the mounting plate is under pressure, the worm wheel will not be lagging, which can ensure the stability of the cooperation between the worm wheel and the worm and reduce the wear between the worm wheel and the worm during use.

[0009] Optionally, a protective cover is further included, wherein the protective cover is arranged on the base platform, and the worm is located inside the protective cover.

[0010] The function of the protective cover is to provide certain protection for the worm.

[0011] Optionally, it also includes an additional plate, which is arranged on the installation plate, and two assembly workbenches are arranged on the additional plate.

[0012] The specific additional plate is detachably set on the mounting plate, and the assembly table is set on the additional plate. When it is necessary to replace the assembly table with a different form and specification, you only need to disassemble the additional plate to remove the assembly table from the mounting plate. After removal, you only need to install the new additional plate with the assembly table on the mounting plate.

[0013] Optionally, an embedded column is provided on the mounting plate, and an interlocking hole is provided on the additional mounting plate, and the embedded column is clamped together with the interlocking hole.

[0014] Optionally, the embedded column is a square embedded column, and the embedded hole is a square embedded hole.

[0015] Optionally, a guide rod is provided on the bracket, the bracket is arranged on the base platform through the guide rod, a guide hole is provided on the pressure plate, and the guide rod is slidably matched with the guide hole.

[0016] Optionally, the guide rod is a cylindrical guide rod, and the guide hole is a circular guide hole.

[0017] Optionally, there are multiple guide rods, and the guide rods are parallel and non-contacting.

[0018] The purpose of providing multiple guide rods is to ensure the stability of the pressure plate during movement and to prevent the cylinder from causing sluggish movement of the pressure plate.

[0019] The beneficial effects of the utility model are as follows: the two end faces of the worm wheel are respectively pressed against the end face of the base and the mounting plate; a plate-like structure rather than an I-shaped structure is formed between the worm wheel, the base and the mounting plate; the base, the worm wheel and the mounting plate have good stability; when the mounting plate is under pressure, the worm wheel will not have a hysteresis phenomenon, which can ensure the stability of the cooperation between the worm wheel and the worm, and reduce the wear between the worm wheel and the worm during use.
