Description

Technical Field

[0001] The utility model belongs to the technical field of rhinestone processing, and specifically relates to a horizontal rotation structure. Background Art

[0002] Rhinestones, also known as crystal diamonds, are mainly composed of crystal glass. They are an accessory for ornaments obtained by cutting artificial crystal glass into diamond facets. Because of their relatively low cost and the dazzling visual effect similar to that of diamonds, they are very popular among people. Rhinestones are generally used in the design of mid-range ornaments.

[0003] During the processing of rhinestones, generally, a row of needles on a fixture is used to stick the rhinestones to the bottom of the needles to fix the rhinestones, and then the rhinestones are processed. After one processing is completed, the fixture needs to be rotated through a horizontal rotation structure, and the fixture is rotated to the opposite station for processing at the next station. Generally, the motor of the existing horizontal rotation structure is arranged below the production line frame, which is not convenient for maintenance. Content of the Utility Model

[0004] The purpose of the utility model is to provide a horizontal rotation structure to solve at least one of the above technical problems.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is:

By installing the speed reducer and the driving motor above the first mounting plate and the rotating frame below the first mounting plate, it is convenient to maintain the speed reducer and the driving motor. The driving motor cooperates with the speed reducer to drive the rotating frame to rotate. The clamping component is used to clamp and fix the fixture with rhinestones, which is convenient to rotate the fixture to the opposite station for processing at the next station.

[0008] Specifically, the transmission assembly includes a transmission shaft, one end of the transmission shaft is transmission-connected to the output end of the reducer, and the other end is fixed to the rotating frame. The transmission shaft is passed through the first mounting plate and is rotatably connected to the first mounting plate. The transmission shaft is used to connect the reducer and the rotating frame, so that the drive motor can drive the rotating frame to rotate. The transmission shaft is used to transmit the power of the drive motor. The rotating frame is installed at the bottom of the first mounting plate, which can make the operation of the rotating frame more stable.

[0009] Furthermore, the transmission assembly also includes a coupling, one end of the coupling is connected to the output end of the reducer, and the other end is connected to an end of the transmission shaft away from the rotating frame.

The coupling can make the connection between the reducer and the transmission shaft more stable and more impact-resistant, and can also compensate for the installation error between the reducer and the transmission shaft.

[0010] Specifically, the clamping assembly includes a clamp back plate, a clamping cylinder and a hook body, the clamp back plates are fixed on opposite sides of the rotating frame, the upper part of the clamp back plate facing away from the rotating frame is protruded to form an upper limit portion, the clamping cylinder is installed on both sides of the top of the clamp back plate, the push rod of the clamping cylinder passes through the clamp back plate and is fixed with the hook body, the clamp is fixed by the set clamp back plate, the upper limit portion and the hook body, after the clamp moves to the clamp back plate on the production line, the clamping cylinder controls the hook body to rise, lifts the clamp from the bottom of the clamp, makes the upper part of the clamp abut against the upper limit portion, and realizes clamping of the clamp.

[0011] Furthermore, the angle between the bottom surface of the upper limit portion and the side surface of the clamp backing plate is an acute angle. After the clamp abuts against the upper limit portion, it is guided close to the clamp backing plate until the side surface of the clamp is close to the clamp backing plate, and the upper part of the clamp is pressed against the upper limit portion, so that the clamp is fixed more firmly.

[0012] Furthermore, a protective tube is provided on the outer periphery of the transmission shaft, the top of the protective tube is fixed to the first mounting plate, and the bottom is rotatably connected to the transmission shaft to cover the transmission shaft to protect the staff from being scratched by the rotating transmission shaft.

The side surface of the adjusting block is provided with an adjusting hole in the horizontal direction. The first mounting plate is mounted on the frame of the diamond drill processing production line. The provided adjusting blocks are used to adjust the positional relationship between the first mounting plate and the frame, facilitating the precise installation of the first mounting plate. The adjusting hole is a threaded hole. Insert a screw into the adjusting hole and turn the screw so that the screw abuts against the frame.

When the rotating frame body rotates and reaches the specified angle, the second limiting block will touch the first limiting block, preventing the rotating frame body from continuing to rotate.

[0016] Further, a reinforcing rib is provided between the cross plate and the vertical plate to strengthen the strength of the bracket.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:
