[0002] When welding dental nails to the middle beam structure in glasses, it is necessary to fix the middle beam in advance to facilitate welding the dental nails. However, the current fixing parts for the middle beam are not convenient to move, so improvement is needed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a fixing mechanism for the middle beam of glasses that is convenient to move, so as to solve the problems raised in the above background technique. It has the advantage of being convenient to move the fixture.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A fixing mechanism for the middle beam of glasses that is convenient to move, including a bottom plate, a first fixing plate is fixedly connected to the bottom plate, the upper side of the first fixing plate is trapezoidal in reverse, a first sliding plate is slidably connected above the first fixing plate, a first sliding member for driving the first sliding plate to move is installed in the first fixing plate, a second fixing plate that is trapezoidal in reverse is fixedly connected to the upper side of the first sliding plate, the second fixing plate is also trapezoidal in reverse, a second sliding plate is slidably connected above the second fixing plate, a second sliding member for driving the second sliding plate to move is installed in the second fixing plate, and a fixture is connected above the second sliding plate.

[0005] By adopting the above technical solution, the first sliding member is used to drive the first sliding plate to move along the length direction of the first fixing plate. After the first sliding plate moves to the desired position, the second sliding member is used to drive the second sliding plate to move to the desired position so that the fixture is in the desired position. The trapezoidal-in-reverse setting increases the stability of the first sliding plate and the second sliding plate when moving.

[0006] As a further scheme of the utility model: The fixture includes a clamping plate fixedly connected to the upper side of the second sliding plate. A clamping groove that runs horizontally through the clamping plate is provided in the middle of the clamping plate. A first clamping block and a second clamping block that are located in the clamping groove are installed in the clamping groove. First inclined blocks and second inclined blocks are integrally connected to the sides of the first clamping block and the second clamping block facing each other respectively. The inclined surface of the first inclined block faces downward, and the inclined surface of the second inclined block faces upward.

[0007] By adopting the above technical solution, the middle beam is placed on the second clamping block, and then the second clamping block is moved towards the first clamping block until the middle beam is clamped and fixed by the first clamping block and the second clamping block. The settings of the first inclined block and the second inclined block facilitate the first clamping block and the second clamping block to clamp the middle beam.

[0008] As a further solution of the present utility model: the second clamping block is provided with a waist-shaped groove penetrating through the second clamping block, and the clamping plate is provided with a threaded groove communicating with the waist-shaped groove.

[0009] By adopting the above technical solution, when the second clamping block does not need to move, the second clamping block is fixed by screwing a bolt into the threaded groove.

[0010] As a further solution of the present utility model: the first sliding member includes a first motor fixedly connected to one end of the first fixing plate, the first motor is connected to a first threaded rod located inside the first fixing plate, the first threaded rod is in threaded connection with a first threaded block, one side of the first threaded block is integrally connected with a first limiting post, and the first sliding plate is provided with a first circular groove for the first limiting post to be inserted into.

[0011] By adopting the above technical solution, starting the first motor drives the first threaded rod to rotate around its own axis. The first limiting post of the first threaded block is inserted into the first circular groove, so that the first threaded block cannot rotate around the first threaded rod. Therefore, the rotation of the first threaded rod makes the first threaded block move along the length direction of the first threaded rod, thereby driving the first sliding plate to move.

[0012] As a further solution of the present utility model: the second sliding member includes a second motor fixedly connected to one end of the second fixing plate, the second motor is connected to a second threaded rod located inside the second fixing plate, the second threaded rod is in threaded connection with a second threaded block, one side of the second threaded block is integrally connected with a second limiting post, and the second sliding plate is provided with a second circular groove for the second limiting post to be inserted into.

[0013] By adopting the above technical solution, starting the second motor drives the second threaded rod to rotate around its own axis. The second limiting post of the second threaded block is inserted into the second circular groove, so that the second threaded block cannot rotate around the second threaded rod. Therefore, the rotation of the second threaded rod makes the second threaded block move along the length direction of the second threaded rod, thereby driving the second sliding plate to move.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] The first sliding member is used to drive the first sliding plate to move along the length direction of the first fixing plate. After the first sliding plate moves to the desired position, the second sliding member is used to drive the second sliding plate to move to the desired position, so that the fixture is in the desired position. The inverted trapezoidal setting increases the stability when the first sliding plate and the second sliding plate move. BRIEF DESCRIPTION OF THE DRAWINGS
