The principle and the advantages of the scheme are as follows: the electromagnetic coil generates magnetism by introducing alternating current to the electromagnetic coil, so that the magnetic poles at two ends of the electromagnetic coil are continuously changed in the current direction changing process due to the introduction of the alternating current, and the electromagnetic coil drives the striking hammer to continuously reciprocate by continuously changing magnetic force to strike the bulge of the repaired part. The supporting piece is used for supporting the concave position of the damaged part of the part, so that when the impact hammer impacts the bulge, the bulged part can be supported by the supporting piece, the bulge in the damaged area is prevented from being knocked by the impact hammer with high strength, the bulge is reversely sunken, a pit is formed on the surface of the bulge, and the improvement of the repairing quality is facilitated.

In the process of beating the bulge of the damaged part, the bulge can be gradually restored to be a plane due to the beating of the beating hammer, the height of the bulge is gradually reduced, and in order to ensure that the beating hammer and the supporting piece can adapt to the height change of the bulge, the piston in the piston cylinder can slide in a reciprocating manner, so that the piston cylinder can continuously drain liquid and absorb liquid; then intermittently electrifying and powering off the electromagnetic valve, and controlling the frequency of electrifying and powering off the electromagnetic valve, so that when negative pressure imbibition is generated in the piston cylinder, the electromagnetic valve can be electrified and opened, the piston cylinder sucks hydraulic oil in the second oil pressure cavity into the piston cylinder through the second oil pipe, thereby reducing the hydraulic oil in the second oil pressure cavity, the second sliding block can move into the second oil pressure cavity, the second sliding block can drive the supporting piece to move in the direction far away from the part, and the automatic adjustment of the position of the supporting piece relative to the part is realized; when flowing back in the piston cylinder, the hydraulic oil of inhaling in the piston cylinder enters into first oil pressure chamber through first oil pipe to make the hydraulic pressure grow in the first oil pressure chamber, first sliding block stretches out from first oil pressure chamber under the effect of oil pressure, and first sliding block drives and hits the hammer and to being close to the part direction removal, has realized hitting like this and has beaten the automatic adjustment of hammer for the position of part. Through this scheme, realized that arch on the part is beating the repair in-process, support piece can shift out from the depressed part of part is automatic gradually, beat the hammer can be automatic gradually to being close to bellied position removal, realized beating the automatically regulated of hammer, support piece position to can adapt to the arch and strikeing highly diminishing gradually of in-process, guarantee that the arch can continuously receive the high frequency of beating the hammer and strike, also avoided support piece's position motionless and hindered bellied restoration simultaneously. Compared with the prior art, the whole process does not need to be stopped to readjust the relative positions of the device and the repaired part, the adjustment of the positions of the whole striking hammer and the supporting piece is more automatic, and the operation is simple and convenient.

When hitting the arch, support piece can receive certain hitting power, and the second sliding block can have reaction force to the hydraulic oil in the second oil pressure chamber, and to avoid the hydraulic oil in the second oil pressure chamber to receive the effort of second sliding block and flow out from second oil pipe, when hitting the hammer and hitting the arch, the solenoid valve outage was closed this moment to can avoid the hydraulic oil in the second oil pressure chamber to be released from second oil pipe by the second sliding block.

According to the process, after the parts are repaired, most of hydraulic oil in the second oil pressure cavity can be transferred to the first oil pressure cavity through the piston cylinder, the second stop valve and the oil pump can be opened at the moment, the first stop valve is closed, the oil pump pumps the hydraulic oil in the first oil pressure cavity into the second oil pressure cavity through the third oil pipe, and therefore the hydraulic oil flows into the second oil pressure cavity again from the first oil pressure cavity, the hydraulic oil in the second oil pressure cavity becomes more, the second sliding block extends out of the second oil pressure cavity, the oil pressure in the first oil pressure cavity is reduced, the first sliding block can enter the first oil pressure cavity, the striking hammer and the supporting piece can reset, and the next part can be repaired. Before the start-up oil pump, through closing first stop valve, first oil pipe is closed like this, and the oil pump can not be through the hydraulic oil suction of first oil pipe, in the piston cylinder of first oil pressure chamber to can have certain hydraulic oil in guaranteeing first oil pipe and the piston cylinder, do benefit to the follow-up continuous use of guaranteeing this device.

Therefore, when the current direction in the electromagnetic coil is changed continuously, the magnetic pole at the end part of the electromagnetic coil is changed continuously, so that the magnet block is attracted and repelled continuously, the lever swings on the third upright column continuously, the lever drives the first upright column to swing continuously through the connecting rod, and the first upright column drives the striking hammer to strike the protrusion continuously. From this, strike the hammer and strike the arch through setting up the lever indirect drive, compare solenoid direct drive strike the hammer, can know according to the laborsaving principle of lever, through the position that sets up the lever fulcrum, solenoid need not to produce great magnetic force and can make to strike the hammer and have great hitting power, because solenoid need not to produce great magnetic force, therefore the electric current size in the solenoid can be less to relatively practice thrift the electric energy.

Preferably, as an improvement, a piston rod of the piston cylinder is rotatably connected with a driving rod, and one end of the driving rod, which is far away from the piston rod, is rotatably connected with the lever.

Therefore, the cushion block can be pushed to move transversely on the frame through the air cylinder, and the lever is provided with a plurality of rotating holes, so that one end of the driving rod, which is rotatably connected with the lever, can be connected into different rotating holes. When the driving rod is connected with the rotating hole far away from the third upright post, the driving rod is far away from the fulcrum part of the lever, the swing amplitude of the driving rod is larger, and the moving amplitude of a piston in a piston cylinder is larger, so that the pressure change of each time in the second oil pressure cavity and the first oil pressure cavity is larger, and the change amplitude of the supporting piece and the striking hammer is larger, so that the driving rod can be suitable for striking parts made of soft materials; when the actuating lever is connected with the rotation hole that is nearer apart from the third stand, the actuating lever is close to the fulcrum position of lever, under the certain condition of the swing range of lever, the swing range of actuating lever can be smaller, piston displacement amplitude in the piston cylinder is also smaller like this, thereby make pressure variation at every turn in second oil pressure chamber and the first oil pressure chamber smaller, support piece and the change range of hitting the hammer are less, thereby can be adapted to comparatively more fragile part and hit and beat, because support piece and the too big part that can make this type of part of the removal change range of hitting the hammer easily fracture when hitting, and this scheme support piece is less with the removal change range of hitting the hammer, be difficult for making this type of part fracture damage.

The top end of the driving rod 22 is rotatably connected to the lever 21 through a pin. In addition, the frame 1 is provided with a support base 29 for supporting the component 14 by means of screws. The support seat 29 is located between the first upright 17 and the second upright, and the part 14 can be supported by the support seat 29. The support base 29 in this embodiment is a lift cylinder. By raising and lowering the lift cylinder, different types of parts 14 can be supported.

The specific implementation process is as follows: a part 14 (such as a car sheet iron which is sunk by a tool in the production, processing and manufacturing process, or a car sheet iron which falls from a processing table to the ground and collides with the ground to form a pit, or other sheet iron, car sheet metal or metal sheets with a pit or a bulge) is placed between the striking hammer 15 and the support 13, so that the arc-shaped part of the support 13 is inserted into the pit of the part 14, and the striking hammer 15 is abutted against the bulge of the part 14. The second cut-off valve 10 and the oil pump 8 are closed, and the first cut-off valve 6 is opened to communicate the first oil pipe 5. The solenoid 26 is energized with alternating current while the solenoid valve 9 is continuously energized and de-energized.

When the electromagnetic coil 26 is energized, the electromagnetic coil 26 generates magnetism, so as to form an electromagnet, and since the current is alternating current, in the process of changing the current flow direction, the magnetic poles at the two ends of the electromagnetic coil 26 are also changed continuously, the electromagnetic coil 26 continuously attracts the magnet block 25 and repels the magnet block 25, so that the left end of the lever 21 continuously swings (it is easy to understand, the magnitude of the magnetic force generated by the electromagnetic coil 26 can be controlled by controlling the frequency and the magnitude of the alternating current passed through the electromagnetic coil 26, so as to control the swing amplitude of the lever 21, in the embodiment, the swing amplitude of the lever 21 is 0-15 °), in the swing process of the lever 21, the right end of the lever 21 drives the first upright post 17 to continuously swing on the rotating seat 28 through the connecting rod 19, and the hitting hammer 15 on the first upright post 17 continuously hits the. In the striking process of the striking hammer 15, the arc-shaped part of the support piece 13 supports the concave part of the damaged part of the part 14, so that the raised part can be supported by the support piece 13, the situation that the raised part of the damaged area is knocked by the striking hammer 15 with high strength to enable the raised part to be reversely sunken to form a pit on the raised surface is avoided, and the improvement of the repairing quality is facilitated. It is easy to understand that by controlling the power-on and power-off frequency of the electromagnetic valve 9, when the striking hammer 15 does not strike the bulge of the part 14, the electromagnetic valve 9 is in the power-on state, and the electromagnetic valve 9 is in the open state; when the striking hammer 15 strikes the protrusion of the component 14, the solenoid valve 9 is in the de-energized state, so that the hydraulic oil in the second oil pressure chamber 12 is not pushed to the right into the second oil pipe 2 by the second sliding block 11 even if the support 13 is struck by the striking hammer 15.

Meanwhile, in the swinging process of the lever 21, the lever 21 drives the driving rod 22 to reciprocate up and down, the driving rod 22 drives the piston 23 to reciprocate vertically in the piston cylinder 24 through the piston rod, so that the piston cylinder 24 continuously sucks and discharges liquid, and the swinging range of the lever 21 is smaller and the lever 21 cannot swing in a larger range because the swinging range of the lever 21 in the embodiment is 0-15 degrees, so that the driving rod 22 cannot swing in a larger range, the lever 21 cannot be clamped by the driving rod 22, and the lever 21 can normally swing. When the driving rod 22 moves upwards, the piston cylinder 24 sucks hydraulic oil in the second oil pressure cavity into the piston cylinder 24 through the second oil pipe 2, the oil pressure in the second oil pressure cavity 12 is reduced, and the second sliding block 11 can slide rightwards into the second oil pressure cavity 12; when the driving rod 22 moves downwards, hydraulic oil in the piston cylinder 24 is discharged, hydraulic oil in the piston cylinder 24 enters the first oil pressure cavity 18 through the first oil pipe 5, the hydraulic oil in the first oil pressure cavity 18 becomes large, the oil pressure in the first oil pressure cavity 18 becomes large, the first sliding block 16 is pushed to the right by the oil pressure against the pulling force of the tension spring, so that the striking hammer 15 moves to the right, and thus when the striking hammer 15 strikes a bulge of the part 14, the first sliding block 16 can be driven to the right by the striking force so that the support piece 13 moves to the right. Thus, with the present embodiment, it is realized that during the striking process of the bulge of the damaged portion, both the support 13 and the striking hammer 15 can automatically move rightward relative to the part 14, so that the bulge is gradually struck to the right and flattened, and the bulge can be gradually recovered.

Through this embodiment, realized that protruding on the part 14 is beating the repair in-process, support piece 13 can shift out from the sunken of part 14 gradually, beat hammer 15 can be gradually to moving near bellied position, realized beating hammer 15, the automatically regulated of support piece 13 position to can adapt to protruding height of beating the in-process and diminish gradually, guarantee that the arch can continuously receive the high frequency of beating hammer 15 and beat, also avoided support piece 13's position motionless simultaneously and hindered bellied restoration. Compared with the prior art, the whole process does not need to be stopped to readjust the relative positions of the device and the repair part 14, the whole position adjustment of the striking hammer 15 and the support 13 is automatic, and the operation is simple and convenient.

When the repair of the part 14 is completed, the part 14 is removed from the apparatus. During the repair process, the hydraulic oil in the second oil pressure chamber 12 enters the first oil pressure chamber 18, so most of the hydraulic oil in the second oil pressure chamber 12 is transferred to the first oil pressure chamber 18, at this time, the second stop valve 10 is opened and the oil pump 8 is started, the first stop valve 6 is closed and the electromagnetic valve 9 is powered off, and the first oil pipe 5 and the second oil pipe 2 are both in an open circuit state. The oil pump 8 pumps the hydraulic oil in the first oil pressure cavity 18 into the second oil pressure cavity 12 through the third oil pipe 7, so that the hydraulic oil flows into the second oil pressure cavity 12 again, the hydraulic oil in the second oil pressure cavity 12 is increased, the second sliding block 11 extends out of the second oil pressure cavity 12, the oil pressure in the first oil pressure cavity 18 is reduced, the first sliding block 16 enters the first oil pressure cavity 18 under the action of the tension spring, the resetting of the striking hammer 15 and the supporting piece 13 is realized, and the next part 14 can be repaired.

It is easy to understand, install the grip block on the top of lift cylinder, carry out the centre gripping through the grip block to the bottom of part 14 to it strikes the in-process and removes the landing to avoid part 14 to hit, makes the part lie in the lift cylinder relatively more stably.

Example 2

With reference to fig. 2, this embodiment is further improved on the basis of embodiment 1, and the cushion block is slidably connected to the frame 1, and the specific sliding connection manner is as follows: the bottom of the frame 1 is provided with a transverse sliding groove, the bottom of the cushion block is welded with a sliding block, and the sliding block is positioned in the sliding groove. The third column 20 is provided with a cylinder 30 for driving the cushion block to slide through a screw, and the lever 21 is provided with a plurality of rotating holes 31 for rotatably connecting the driving rod 22 and the lever 21, that is, the top end of the driving rod 22 is rotatably connected with the lever 21 through the matching of a pin shaft and the rotating holes 31.

Therefore, when the relatively soft part 14 is repaired, the cushion block is driven to move leftwards by the air cylinder 30, the driving rod 22 is connected with the rotating hole 31 which is far away from the third upright post 20, at the moment, the driving rod 22 is far away from the fulcrum part of the lever 21, the swing amplitude of the driving rod 22 is large, so that the moving amplitude of the piston 23 in the piston cylinder 24 is also large, more hydraulic oil is sucked or discharged by the piston cylinder 24 each time, the pressure change in each time of the second oil pressure cavity 12 and the first oil pressure cavity 18 is large, the moving amplitude of the supporting piece 13 and the striking hammer 15 each time is large, and the device can be suitable for striking the part 14 (such as a copper metal plate) made of a relatively soft material, because the part 14 made of the material has good toughness, the part is not easy to break when deformed greatly, and therefore, the moving amplitude of the supporting piece 13 and the striking hammer 15 can be relatively large, therefore, the repair efficiency is improved, and the part cannot be damaged.

When repairing the fragile part 14, the air cylinder 30 drives the cushion block to move rightwards, the top of the driving rod 22 is connected with the rotating hole 31 which is closer to the third upright post 20, because the driving rod 22 is close to the fulcrum part of the lever 21, in the case of a constant amplitude of oscillation of the lever 21, the amplitude of vertical oscillation of the driving rod 22 will be relatively small, so that the movement amplitude of the piston 23 in the piston cylinder 24 is smaller, the suction or discharge amount of hydraulic oil in the piston cylinder 24 is smaller each time, so that the pressure change in the second oil pressure chamber 12 and the first oil pressure chamber 18 is relatively small, the amplitude of each movement of the support 13 and the striking hammer 15 is relatively small, and the striking hammer can be adapted to strike relatively fragile parts 14, since the support 13 and the striking hammer 15 are moved by too much so that the part 14 of this type is broken when struck, it is necessary to change the position of the support 13 and the striking hammer 15 slowly each time.

Example 3

The right side surface of the hammer 15 in this embodiment is bonded with a flexible member, which is a rubber block in this embodiment. The flexible part can play the cushioning effect to hitting the collision effort of beating hammer 15 and part, avoids beating hammer 15 harder, leads to the paint on the part 14 to drop. Therefore, when the device in the scheme repairs the position with small deformation, the paint can be protected as much as possible, and the paint spraying is not needed after the repair, so that the cost required by the repair is reduced.

The foregoing is merely an example of the present invention and common general knowledge in the art of designing and/or characterizing particular aspects and/or features is not described in any greater detail herein. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several variations and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
