DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example

[0026] See also Figure 1-10 The present invention is an automatic opening and closing rear column structure for gear shaft processing, including a rear column body 1, a drag plate 2, a driving element 3, a top bracket 4, a rotary shaft 5, a first locking flange 6, a second locking flange 7, a locking shaft assembly 8, an upper and lower cylinder 9, a top assembly 10, a connecting element 301, a conical pin 501, a rotary support element 502, a piston flange 801, a locking piston shaft 802, and an elastic element 803.

[0027] The rear column body 1 and the carriage 2 are provided with guide rails, and the two parts cooperate with each other through the guide rail surface, so that the carriage 2 can slide up and down along the guide rail surface of the rear column body 1;

[0028] The driving element 3 is used to provide the rotational force required for automatic opening and closing, and is fixed to the carriage 2 by screws;

[0029] The rotary shaft 5 is connected to the power output shaft of the driving element 3 through the connecting element 301. At the same time, the rotary shaft 5 passes through the inner hole of one side of the top bracket 4 and is fixed to the top bracket 4 through two conical pins 501. In this way, when the driving element 3 rotates, the top bracket 4 can be driven to rotate in the direction close to the carriage 2, so that the top bracket 4 is automatically closed.

[0030] The locking shaft assembly 8 is composed of a piston flange 801, a locking piston shaft 802, and an elastic element 803. The piston flange 801 is fixed on the top bracket 4. The locking piston shaft 802 and the elastic element 803 are installed in the inner hole of the top bracket 4. The top bracket 4 is close to the mounting hole of the locking shaft assembly 8 and has an oil hole.

[0031] When the top bracket 4 rotates to a closed state, the top bracket 4 needs to be automatically locked. At this time, the locking piston shaft 802 is pushed out toward the piston pressing surface of the piston flange 801 by the elastic force under the action of the elastic element 803, so that the inclined end surface on the exposed axial surface of the locking piston shaft 802 contacts the inclined end surfaces of the inner holes of the first locking flange 6 and the second locking flange 7, and is continuously pressed, thereby realizing the automatic locking effect of the top bracket 4.

[0032] The top assembly 10 is installed on the top bracket 4, the bases of the upper and lower oil cylinders 9 are fixed to the rear column body 1 by screws, and the telescopic rods of the upper and lower oil cylinders 9 are fixed to the drag plate 2. When the upper and lower oil cylinders 9 are oiled, the telescopic rods in the cylinders can be extended and retracted up and down, driving the drag plate 2, the top bracket 4, and the top assembly 10 to slide up and down along the guide surface of the rear column body 1, thereby pressing and positioning the gear shaft parts and releasing the compression through the top on the top assembly 10.

[0033] When hydraulic oil is passed through the oil hole on the top bracket 4, the pressure of the hydraulic oil acts on the piston surface of the locking piston shaft 802, causing the locking piston shaft 802 to resist the elastic force of the elastic element 803 and retract into the inner hole of the top bracket 4.

[0034] The oblique end surface on the exposed axial surface of the locking piston shaft 802 gradually moves away from the oblique end surfaces of the inner holes of the first locking flange 6 and the second locking flange 7, the contact surface loses the locking pressure, and the exposed shaft of the locking piston shaft 802 completely withdraws from the inner holes of the first locking flange 6 and the second locking flange 7, so that the top bracket 4 is automatically unlocked.

[0035] After the top bracket 4 is automatically unlocked, the top bracket 4 is rotated away from the carriage 2 through the rotary motion of the driving element 3, thereby realizing the automatic opening function of the top bracket 4.

[0036] The standard parts used in the present invention can all be purchased from the market, and can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art. The control method is automatically controlled by a control unit. The control circuit of the control unit can be realized by simple programming by technicians in this field, which is common knowledge in this field, so the control method and circuit connection are not explained in detail in the present invention.

[0037] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that technicians in the relevant technical field can better understand and utilize the present invention.
