Description

Technical Field

[0001] This application relates to the field of top seats, and in particular to a top seat with a leveling function. Background Art

[0002] A cantilever is a mechanical structure for installing a control box or an operation box, commonly found on general equipment such as machine tools. The top seat is a connecting structure between the cantilever and the general equipment.

[0003] Reference Figure 1 , the cantilever includes a top seat 81, a cantilever horizontal pipe 82, a cantilever vertical pipe 83, and a corner joint 84. The top seat 81 is rotatably connected to the top wall of the general equipment. The top seat 81 is connected to the cantilever horizontal pipe 82. The cantilever vertical pipe 83 is connected to the cantilever horizontal pipe 82 through the corner joint 84. The control box 85 is used to be rotatably connected to the cantilever vertical pipe 83.

[0004] Due to reasons in some factories, the general equipment cannot ensure a horizontal placement state, resulting in the cantilever vertical pipe not being perpendicular to the ground. Under the influence of gravity, it will drive the cantilever horizontal pipe to rotate relative to the top seat, and the control box cannot hover relative to the general equipment, and the control box is prone to collide with the general equipment. Summary of the Invention

[0005] In order to ensure that the cantilever vertical pipe corresponding to the top seat is in a horizontal state and reduce the collision between the control box and the general equipment, this application provides a top seat with a leveling function.

[0006] A top seat with a leveling function provided by this application adopts the following technical solution: A top seat with a leveling function includes a mounting seat, a balance table, a connecting seat connected to the cantilever horizontal pipe, and an adjusting component. A ball head is provided on the mounting seat. The balance table is ball-jointed on the ball head. The connecting seat is arranged on the balance table. The adjusting component is used to keep the balance table in a horizontal state.

[0007] By adopting the above technical solution, when the general equipment cannot maintain a horizontal state, the balance table is ball-jointed to the mounting seat. Therefore, the operator can adjust and rotate the balance table, and through the adjusting component, the balance table is in a horizontal state. After the connecting seat is in a horizontal state, the cantilever horizontal pipe can be installed on the connecting seat, and the cantilever vertical pipe can be installed on the cantilever horizontal pipe through the corner joint. Since the mounting seat is in a horizontal state, the cantilever vertical pipe will also maintain a vertical state, and the cantilever vertical pipe will not rotate under the influence of gravity, reducing the collision between the control box and the general equipment.

[0008] Optionally, the adjusting assembly includes four mounting pipes, four sliding columns, and two control members. The four mounting pipes are circumferentially distributed on the mounting seat along the circumference of the ball head. The four sliding columns correspond to the four mounting pipes. The sliding columns are slidably connected within the mounting pipes. A communicating pipe is provided on the side wall of the mounting pipe. The communicating pipe communicates with the mounting pipe. Hydraulic oil is provided within the communicating pipe. The control member is used to control the introduction of hydraulic oil into two separated mounting pipes.

[0009] By adopting the above technical solution, when the balance table needs to be adjusted to a horizontal state, the staff can introduce hydraulic oil into the mounting pipe through the control member. The hydraulic oil jacks up the sliding column, and the sliding column causes the balance table to rotate until the balance table is in a horizontal state. The adjusting assembly has a simple structure and is convenient to operate.

[0010] Optionally, the control member includes a control block, two plugging rods, and a control bolt. The two plugging rods are respectively slidably connected within the communicating pipes corresponding to two separated mounting pipes. The control block is slidably connected to the mounting seat. The control bolt is used to abut the control block against the mounting seat.

[0011] By adopting the above technical solution, when the balance table needs to be adjusted, the staff can drive the control block to move through the control bolt. The control block drives the two plugging rods to slide respectively within the corresponding communicating pipes. The hydraulic oil in the communicating pipe will enter the mounting pipe. When the hydraulic oil in one communicating pipe enters the mounting pipe, the hydraulic oil jacks up the sliding column. At this time, the hydraulic oil in the other corresponding mounting pipe will enter the communicating pipe under the drive of the plugging rod, and the sliding column will retract into the mounting pipe, realizing the balance adjustment of the balance table, reducing the force on the ball head. When the adjustment of the balance table is completed, the staff can tighten the control bolt to abut the control block against the mounting seat, so that the balance table can maintain a balanced state. The control member further improves the convenience of operating the balance table and also ensures the reliability of the balance table.

[0012] Optionally, an operation hole for facilitating the operation of the control bolt is provided on the balance table. The operation hole penetrates the balance table, and the head of the control bolt passes through the operation hole.

[0013] By adopting the above technical solution, since the balance table is ball-jointed to the mounting seat, the staff can directly operate the operation bolt through the operation hole, improving the convenience of controlling the operation bolt.

[0014] Optionally, two spirit levels are provided on the balance table. The length directions of the two spirit levels are perpendicular to each other.

[0015] By adopting the above technical solution, the spirit levels on the balance table facilitate the staff to know whether the balance table is adjusted to a horizontal state.

[0016] Optionally, the mounting seat is connected to a universal device by bolts, and a pre-tightening member is also provided on the mounting seat, wherein the pre-tightening member includes a sliding block, a pre-tightening spring, four support rods and four torsion springs, the sliding block is slidingly connected to the mounting seat in a direction approaching or moving away from the balancing platform, the pre-tightening spring is used to keep the sliding block away from the balancing platform and exposed from the mounting seat, four support rods are evenly distributed on the sliding block, one end of the support rod is rotatably connected to the sliding block, the support rod is inclined, the other end of the support rod is abutted against the balancing platform, the support rod passes through the mounting seat, and the torsion spring is used to keep the support rod abutted against the mounting seat.

[0017] By adopting the above technical solution, when there is a gap between the installation of the mounting seat and the general equipment, even if the balancing platform is adjusted to a horizontal level, during subsequent use, the mounting seat and the general setting will move relative to each other due to frequent rotation, making it impossible for the balancing platform to ensure a balanced state; when there is a pre-tightening member in the equipment, when the mounting seat is not adjusted into place, the four support rods will abut against the balancing platform, and the balancing platform cannot be adjusted, forcing the staff to tighten the bolts between the mounting seat and the general equipment. During the installation process, the staff first abuts the sliding block against the general equipment, and then connects the mounting seat to the general equipment with bolts. At this time, the sliding block will overcome the pre-tightening spring and rotate toward the direction of the balancing platform. The distance between the sliding block and the balancing platform changes, and the support rod always remains abutted against the mounting seat under the action of the torsion spring. The contact position of the support rod and the mounting seat changes, and the inclination angle of the support rod changes. The end of the support rod that originally abutted against the balancing platform is separated from the balancing platform. At this point, the balancing platform is in a free state, and the state of the balancing platform can be adjusted by the adjustment component. The reliability of the connection between the mounting seat and the general equipment is ensured by the pre-tightening member.

[0018] Optionally, an anti-skid plate is provided on the lower end surface of the sliding block.

[0019] By adopting the above technical solution, the anti-skid plate contacts the universal device with the mounting seat first, and the anti-skid plate can increase the friction between the top seat and the universal device, making it easier to connect the mounting seat and the universal device through bolts.

[0020] Optionally, the support rod is provided with a rounded corner for avoiding the balancing platform.

[0021] By adopting the above technical solution, the sliding block moves close to the balancing platform to drive the support rod to rotate, and the rounded corners allow the support rod to smoothly move away from the balancing platform, reducing hard contact with the balancing platform, and the structure is reasonable.

[0022] Optionally, the connecting seat is provided with mounting bolts, and the mounting bolts are used to set the mounting seat on the balancing platform.

[0023] By adopting the above technical solution, after the balance table is adjusted, the staff then installs the connecting seat onto the balance table through the installation bolts. At this time, the connecting seat is always in a horizontal state, and the installation of the connecting seat is convenient.

[0024] Optionally, an insertion pipe is provided on the balance table, a through hole is provided on the connecting seat, and the insertion pipe is used for being inserted into the through hole.

[0025] By adopting the above technical solution, the cooperation of the insertion pipe and the through hole facilitates the positioning of the connecting seat and improves the connection convenience of the installation bolts.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The adjusting assembly is used to level the balance table, so that the cantilever vertical pipe corresponding to the top seat is in a vertical state, thereby reducing the collision between the control box and the general equipment; 2. The pre-tightening member enables the staff to ensure that the mounting seat is installed in place before adjusting the balance table. Description of the Drawings
