A pillar is installed in the first storage cavity, and a sliding hole is provided on the pillar to be plugged into the second guide rod.

[0010] Wherein, a second storage cavity is provided on both sides of the lifting platform, and a side tipping platform is hinged in the second storage cavity, and the side tipping platform can swing in and out of the second storage cavity.

[0011] The upper end surface of the side tipping platform is flush with the table surface of the lifting platform when the side tipping platform is swung to the highest position; the upper end surface of the side tipping platform is flush with the side surface of the lifting platform when the side tipping platform is swung to the lowest position.

[0012] Among them, the side flipping platform is rotatably connected to the second storage cavity through a rotating shaft, the axial direction of the rotating shaft is consistent with the moving direction of the translation platform, a third storage cavity is provided in the side flipping platform, a first opening connecting the second storage cavity and the third storage cavity is provided between the two, a pendulum block is fixedly connected to the inner side of the side flipping platform, a mounting frame is installed in the third storage cavity, a linear drive mechanism is installed on the mounting frame, a mounting block is installed on the driving end of the linear drive mechanism, and a connecting rod is hinged between the pendulum block and the mounting block.

[0016] Wherein, a locking bolt for being spun onto the top surface of the wheel frame is threadedly connected to the second supporting block.

[0017] After adopting the above technical solution, the beneficial effects of the present invention are:

[0018] Since the telescopic workbench of the present invention includes a fixed seat, two translation platforms that move toward or away from each other are installed on the fixed seat, the bottoms of the two ends of the translation platform are respectively fixed with a first support block and a second support block, the first support block is slidably connected to the fixed seat, the bottom of the second support block is provided with a support wheel, and a first driving mechanism for driving the translation platform to move horizontally is installed on the translation platform; the fixed seat has a built-in first storage cavity, a lifting platform is provided in the first storage cavity, and a second driving mechanism for driving the lifting platform to move vertically is provided in the first storage cavity. The two translation platforms are respectively provided with a first process and a second process; the first driving mechanism drives the two translation platforms to move in a direction away from the fixed seat until the second opening of the first storage cavity is completely exposed, the second driving mechanism drives the lifting platform to rise until the table surface of the second lifting platform is flush with the table surface of the translation platform, the first driving mechanism drives the two translation platforms to move relative to each other, so that the two translation platforms move toward each other, until the opposite ends of the two translation platforms are in contact with the corresponding ends of the lifting platform, at this time, the total working surface of the workbench includes the table surfaces of the two translation platforms and the table surface of one lifting platform. The lifting platform is used to set up the third process, and arrange the third process between the first process and the second process, so as to realize fast and efficient process arrangement and improve production efficiency.

[0019] Since the second storage cavity is provided on both sides of the lifting platform, a side-turning platform is hinged in the second storage cavity, and the side-turning platform can swing in and out of the second storage cavity. The lifting platform is raised and lowered to a position higher than the translation platform, so that the side-turning platform can swing from the second storage cavity and press against the second opening, and then the lifting platform is lowered to a position where the lifting platform is flush with the translation platform. The side-turning platform is used to ensure that the lifting platform can completely cover the second opening, and the side-turning platform can also form a support for the lifting platform, further improving the stability of the lifting platform after it is raised.

[0020] Since the upper end surface of the side tipping platform is flush with the table top of the lifting platform when the side tipping platform is swung to the highest position, the upper end surface of the side tipping platform and the table top of the lifting platform are combined into a complete table top structure, thereby ensuring the flatness of the total table top; the upper end surface of the side tipping platform is flush with the side surface of the lifting platform when the side tipping platform is swung down to the lowest position, so that the side tipping platform can be completely stored in the second storage cavity after swinging down.

[0021] Since the side-turning platform is rotatably connected to the second storage chamber via a rotating shaft, the axial direction of the rotating shaft is consistent with the moving direction of the translation platform, a third storage chamber is provided in the side-turning platform, a first opening is provided between the second storage chamber and the third storage chamber to connect the two, a swing block is fixedly connected to the inner side of the side-turning platform, a mounting frame is installed in the third storage chamber, a linear drive mechanism is installed on the mounting frame, a mounting block is installed on the driving end of the linear drive mechanism, and a connecting rod is hinged between the swing block and the mounting block. The linear drive mechanism is a cylinder or an electric push rod, a mounting block is installed on the driving end of the linear drive mechanism, and the two ends of the connecting rod are respectively rotatably connected to the swing block and the mounting block via a connecting shaft, so that the linear drive mechanism drives the mounting block to rise and fall, thereby driving the swing block to swing through the connecting rod, realizing the synchronous swing of the side-turning platform, thereby realizing the rapid entry and exit of the side-turning platform in the second storage chamber; in this embodiment, two swing mechanisms are arranged at intervals along the length direction of the side-turning platform, and the two swing mechanisms act synchronously.

[0022] Since the bottom surface of the translation stage is equipped with a first roller, the first roller rolls against the top surface of the fixed seat, and the top of the end surface of the fixed seat is equipped with a second roller, the second roller rolls against the bottom surface of the translation stage. The smoothness and stability of the movement of the translation stage along the fixed seat are achieved through the synchronous rolling support of the first roller and the second roller.

[0023] Since the supporting wheel includes a wheel frame and a wheel body installed on the wheel frame, at least two third guide rods are vertically fixed to the top surface of the wheel frame, the third guide rods are slidably connected to the second support block, and a compression spring is sleeved on the third guide rod. The compression spring is elastically supported between the second support block and the wheel frame. The supporting wheel can move up and down by sliding the third guide rod in the through hole, and a downward elastic supporting force is applied to the supporting wheel by the compression spring, so that the supporting wheel has the function of elastic expansion and contraction, which can ensure the smoothness and stability of the movement of the translation platform when the translation platform moves along an undulating ground.

[0024] Since the second support block is threaded with a locking bolt for spinning onto the top surface of the wheel frame, after the translation platform completes its movement, the locking bolt is tightened so that the locking bolt is pressed tightly against the top surface of the wheel frame, thereby fixing the wheel frame and ensuring effective fixation of the translation platform after it completes its movement.

[0025] In summary, the present invention solves the technical problem of low production efficiency caused by production process change in the prior art. The present invention improves the efficiency of process change, reduces the impact on processing accuracy during technical transformation, and also has the advantage of quick and convenient adjustment.
