[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0021] Embodiment: as shown in the accompanying drawings, Figures 1-3 A bidirectional shock absorption balancer comprises a main disc 1, a distributor 2 arranged at the center of the main disc 1, a balance turntable 3 sleeved on the outer side of the distributor 2, a plurality of air hammers 4 arranged in the circumferential direction of the main disc 1, a probe 5 connected to the air hammer 4, a connecting rod mechanism arranged between the probe 5 and the balance turntable 3, and the connecting rod mechanism and the air hammer 4 are arranged in one-to-one correspondence, and the plurality of connecting rod mechanisms are arranged in a circular array along the balance turntable 3 with the center.

[0022] As shown in the accompanying drawings, Figures 1-2 In the embodiment, the connecting rod mechanism comprises a pull rod 6 hinged to the balance turntable 3 and a sliding rod 7 hinged to the probe 5. The end of the pull rod 6 close to the sliding rod 7 is provided with a sleeve 8, the end of the sleeve 8 close to the sliding rod 7 is provided with an opening, and the end of the sliding rod 7 is located in the sleeve 8 and can slide along the sleeve 8. The sleeve 8 is integrally arranged with the pull rod 6, and can also be arranged in a split body, and if arranged in a split body, the two can be fixedly connected. The sliding rod 7 is sleeved with a first spring 9 and a second spring 10, in the embodiment, the first spring 9 is sleeved on the part of the sliding rod 7 located in the sleeve 8, and the second spring 10 is sleeved on the part of the sliding rod 7 located outside the sleeve 8. The end of the sliding rod 7 located in the sleeve 8 is connected with a limiting nut 11, and the limiting nut 11 is used for limiting the second spring 10, so as to ensure that the second spring 10 will not slide out of the end. The limiting nut 11 and the end of the sliding rod 7 are connected through threads.

[0023] As shown in the accompanying drawings, Figure 2 The end of the sleeve 8 is connected with a positioning cap 12, and the positioning cap 12 and the sleeve 8 are fixedly connected through threads. The sliding rod 7 penetrates through the positioning cap 12 and can slide along it, the inner diameter of the positioning cap 12 is smaller than the outer diameter of the first spring 9 and the second spring 10, so that the first spring 9 and the second spring 10 are separated, and when the sliding rod 7 slides, the end of the first spring 9 or the second spring 10 close to the positioning cap 12 can be positioned, so that the first spring 9 or the second spring 10 is compressed to realize buffering.

[0024] As shown in the accompanying drawings, Figure 2As shown, the length of the sleeve 8 inside is greater than the length of the slide rod 7 in the sleeve 8, so that the slide rod 7 can slide in the sleeve 8. When the slide rod 7 slides towards the pull rod 6, the second spring 10 is compressed to achieve buffering, and when the slide rod 7 slides away from the pull rod 6, the first spring 9 is compressed to achieve buffering. Thus, no matter how the slide rod 7 slides, there is buffering, so that the entire linkage mechanism can achieve bidirectional buffering and shock absorption.

[0025] Moreover, the lengths of the first spring 9 and the second spring 10 are much greater than the length of the spring in the prior art, so that better buffering can be achieved, the spring will not be broken due to short buffering distance and impact, the entire linkage mechanism is protected, and the service life of the linkage mechanism is prolonged. Moreover, the structure is simpler than that in the prior art, and the assembly is simpler.

[0026] As shown in the figure, Figures 1-3 The pull rod 6 is connected with the balance disc 3 through a first rotating head 13, and the slide rod 7 is connected with the probe 5 through a second rotating head 14. The first rotating head 13 and the second rotating head 14 are both U-shaped hinge joints. One end of the first rotating head 13 is fixed with the pull rod 6, and the other end is connected with the balance disc 3 through a hinge shaft. The probe 5 includes a ruler body arranged along the movement direction of the air hammer 4 and a ruler seat 15 fixedly connected with the air hammer 4. One end of the second rotating head 14 is fixed with the slide rod 7, and the ruler seat 15 extends along the surface of the main disc 1 and is hinged with the other end of the second rotating head 14 through a hinge shaft.

[0027] When moving, the probe 5 drives the ruler seat 15 to move forward, the ruler seat 15 drives the second rotating head 14 to rotate and move, the second rotating head 14 drives the slide rod 7 to move away from the pull rod 6, the pull rod 6 drives the balance disc 3 to rotate, and at the same time, the first spring 9 is compressed to buffer the movement. The balance disc 3 restricts the movement amplitude of the linkage mechanism in turn under the action of the three linkage mechanisms, the pull rod 6 drives the slide rod 7 to return, and the second spring 10 is compressed to buffer the movement.

[0028] In the embodiment, the main disc 1 is provided with one, and three air hammers 4 are arranged along the circumference of the main disc 1. The number of air hammers 4 can be set according to actual conditions, and is not specifically limited. The probe 5 corresponds to the air hammer 4 one by one, and the balance disc 3 is also provided with one, which is circular. The balance disc 3 is arranged concentrically with the distributor 2 and is connected through a bearing, so that the balance disc 3 can rotate freely along the distributor 2. The connection points of the linkage mechanisms and the balance disc 3 are uniformly distributed along the circumference of the balance disc 3. The balance disc 3 can be provided with multiple connection points along the circumference, but in the embodiment, there are three groups of linkage mechanisms, and the connection points of the balance disc 3 are three.

[0029] In use, the gas source passes the gas into the air hammers 4 through the distributor 2 and pushes the air hammers 4 to move forward, the three air hammers 4 move forward at the same time, and the respective rulers 5 are driven to move forward, the rulers 5 drive the corresponding connecting rod mechanisms to pull the balance turntable 3 to rotate, if the distance of the forward movement of one or two air hammers 4 is different from the other due to the shaking of the machine, the pulling force of the corresponding connecting rod mechanism on the balance turntable 3 will be large, so that the rotating angle of the balance turntable 3 is increased, since the three connecting rod mechanisms are centrally symmetric along the balance turntable 3, the balance turntable 3 will drive the other air hammers 4 to increase the movement range of the corresponding connecting rod mechanisms, and the connecting rod mechanisms will react on the corresponding air hammers 4, so that the three connecting rod mechanisms always move at the same time under the driving of the balance turntable 3, and the movement range is always equal, so that the purpose of synchronous adjustment of the air hammers 4 during the tapping is achieved.
