[0016] The specific implementation of the utility model will be described in detail below in combination with the drawings and the preferred embodiments.

[0017] Please refer to Figure 1 As shown in the figure, a transversely-slidable single-axis rotary positioner mechanism includes a support base 1, a sliding system 2, a locking unit 3, an active end 4 of a positioner, a driven end 5 of the positioner, and a rotary position base 6. The active end and the driven end of the positioner are respectively fixed on the sliding system through a welded support 7, the sliding system is installed on the support base and realizes sliding movement by a sliding block and a cylinder, and the sliding to the loading position and the working position is locked by the locking unit. After locking, the product required is rotated by the active end of the positioner, the driven end of the positioner, and the rotary position base, the product positioning equipment switching and loading are performed.

[0018] As Figure 2 shown, the welded frame of the support base is welded from profile square tubes, and the base is fixed at the bottom as an adjustable leveling foot. When the whole equipment is adjusted and fixed, it is welded and fixed on site to ensure that the overall size and horizontal size of the equipment will not be displaced in the later period.

[0019] As Figure 3As shown, the sliding system is fixed on the support base as a whole, mainly composed of a telescopic cylinder 21, a sensor 22, a buffer 23, a welded sliding base 24 and a guide rail 25. The cylinder mainly provides power for the sliding system. The welded sliding base is fixed on the sliding block. The guide rail, the sensor and the buffer are respectively fixed on the support base. When the cylinder extends or retracts, the welded sliding base moves with the guide rail and slides on the guide rail. When the sliding reaches the upper piece or the working position, the welded sliding base first contacts the buffer for deceleration, then contacts the limiting block, and finally the sensor at the upper piece or the working position feeds back the specific position of the welded sliding base to the robot.

[0020] As shown in the figure, Figure 4 The locking unit is fixed on the welded sliding base of the sliding system and is divided into a clamping cylinder 31, an upper piece position limiting block 32 and a working position limiting block 33. When the welded sliding base slides to the upper piece position or the working position, the welded sliding base is blocked by the limiting block, and the upper piece position or the working position sensor feeds back the signal. The corresponding upper piece position locking unit or lower piece position locking unit clamping cylinder clamps, and the position of the welded sliding base is locked. When the welded sliding base needs to be changed, the corresponding clamping cylinder is opened, and the welded sliding base starts to move.

[0021] The driven end of the variable position machine is fixed on the welded sliding base of the sliding system and is composed of a welded support seat, a motor, a speed reducer and a sensor. The welded support seat is welded by profile square tubes. When the variable position machine needs to rotate, the motor provides power source for the whole variable position machine, starts to rotate, and the speed reducer provides stable transmission ratio for the whole variable position machine, so that the whole variable position machine rotates at a certain speed.

[0022] The driven end of the variable position machine is fixed on the welded sliding base of the sliding system and is composed of a welded support seat, a rotating shaft, a bearing mounting seat, a ball bearing, a bearing inner ring fixing sleeve, a bearing outer ring locking sleeve and a locking nut. The welded support seat is welded by profile square tubes. The bearing seat is installed on the welded support seat. The ball bearing is installed in the bearing seat. The rotating shaft is connected with the ball bearing inner ring. The bearing is fixed by the bearing inner ring fixing sleeve and the locking nut. The bearing outer ring locking sleeve is directly connected with the bearing seat to lock the bearing outer ring. When the driving end of the variable position machine starts to rotate, the power is transmitted to the driven end through the rotary variable position base, and the driven end also rotates with the driving end.

[0023] The rotary variable position base is welded by four plates into a four-square body. The rotary variable position base is connected with the driving end of the variable position machine at one end and with the driven end of the variable position machine at the other end. The side surface is provided with a support to connect with the equipment for fixing the products to be produced. The four side surfaces can be connected with the fixing equipment for four kinds of products.

[0024] The initial state of the positioner is at zero position, the telescopic cylinder is in the extended state, the slide table slides to the upper piece position, the upper piece position locking unit clamping cylinder is in the clamping state, ensuring the locking of the slide table position, preventing the position of the slide table from moving during the manual upper piece process. After the manual upper piece is completed, the positioner rotates the base by 180°, moving the workpiece to the robot side. At this time, the upper piece position locking unit clamping cylinder is opened, the telescopic cylinder is retracted, and the slide table slides into the work position at the same time. When the slide table contacts the buffer, it starts to decelerate, and the work position limiting block completely blocks the movement of the slide table. At the same time, the work position sensor detects that the slide table is in place, feeds back a signal to the robot, the work position locking unit clamping cylinder is clamped in place, completely ensuring that the position of the slide table will not move, and the robot starts to work. After the robot works, the work position locking unit clamping cylinder is opened, the telescopic cylinder starts to extend, and the slide table starts to slide to the upper piece position. At the same time, the rotary position base reverses by 180°. When the slide table contacts the buffer, it starts to decelerate, and the upper position limiting block completely blocks the movement of the slide table. At the same time, the upper piece position sensor detects that the slide table is in place, feeds back a signal to the robot, the upper piece position locking unit clamping cylinder is clamped in place, completely ensuring that the position of the slide table will not move, and the manual upper piece is performed again.

[0025] It should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the scope of the present application.
