Description

Technical Field

[0001] The invention belongs to the technical field of transformer production, and in particular relates to an insulating paperboard compacting vibration hammer. Background Art

[0002] The transformer production process requires the parts to be compacted at multiple stages. The most common and typical scenario is the installation of transformer insulation parts, where multiple layers of insulation parts need to be compacted with appropriate force. Currently, most sites use manual compaction or rubber hammer compaction. These two methods often make it difficult to control the force. Manual compaction requires the operator to have a high level of self-perception of force, while rubber hammer compaction makes it difficult to maintain uniform force. Summary of the invention

[0003] The present invention provides an insulating paperboard compacting vibration hammer to solve the problems in the above-mentioned background technology.

[0004] The technical problem solved by the present invention is achieved by adopting the following technical solutions:

The transmission part is installed on the upper side of the cover shell, the vibration part is installed on the lower side of the cover shell and connected to the transmission part, and the hammer part is installed on the bottom of the cover shell.

[0006] The cover shell comprises an upper cover shell, a handle, a boss and a lower cover shell, wherein the upper cover shell side is connected to the handle, an upper circular ring is provided on the inner side of the bottom of the upper cover shell, and a lower circular ring is provided on the middle and lower part of the inner side of the lower cover shell.

[0007] The transmission part includes a rotating shaft, a crank, a connecting rod and a pull rod. The rotating shaft is hinged on the boss and connected to the power source in the handle to transmit rotation. The crank is fixedly connected to the rotating shaft. The crank is hinged to the connecting rod. The bottom of the connecting rod is hinged to the pull rod. The bottom of the pull rod has a paddle, which is located inside the vibration part. The vibration part includes a vibrator, a cover plate, an inner spring and an outer spring. The vibrator is a shell structure. The cover plate is installed on the top of the vibrator. The cover plate covers the two inner springs and the paddle inside the vibrator. The middle part of the outer side of the vibrator has a vibrator boss. An outer spring is respectively fitted above and below the vibrator boss. The two inner springs are respectively located on the upper and lower sides of the paddle. The hammer part includes a bottom threaded area, a hammer head and an inner cavity surface. The hammer part is installed at the bottom of the lower cover shell through the bottom threaded area. The bottom of the hammer part is the hammer head. The inside of the hammer part has an inner cavity surface. The height of the inner cavity surface is determined according to actual needs.

[0008] Furthermore, the handle has a built-in driving component and a power supply device.

[0009] Furthermore, a boss is provided on the inner side of the upper cover shell at a position directly opposite to the handle, and the boss is connected to the transmission part. The lower part of the upper cover shell is connected to the lower cover shell.

[0010] Furthermore, grooves are provided on both sides of the top of the upper cover shell, and the grooves can prevent the transmission part from interfering with the side wall of the upper cover shell when the transmission part rotates.

[0011] Furthermore, the outer side of the bottom of the upper cover shell has an upper threaded area, and the top of the lower cover shell has a lower threaded area, and the lower threaded area cooperates with the upper threaded area to achieve docking installation of the upper cover shell and the lower cover shell.

[0012] Furthermore, the top of the pull rod is provided with two ears, and the two ears are connected to the connecting rod.

[0013] Furthermore, the bottom of the vibrator passes through the lower ring.

[0014] Furthermore, the hammer head is covered with cork material or rubber material.

[0015] The beneficial effects of the present invention are:

[0016] The invention is used for the insulating paperboard pressing operation in the transformer production process. The invention has two groups of springs which jointly drive the vibrator to vibrate, generate vibration excitation for the hammer head at the striking part, and compact the insulating paperboard with adjustable and controllable frequency and strength.

[0017] The way to adjust the knocking force is: if a larger knocking force is required, the height of the inner cavity surface can be designed to be higher, so that the vibrator can directly knock the inner cavity surface every time it moves downward, that is, directly transmit the vibration of the vibrator; if a smaller knocking force is required, and only the inertia moment of the vibrator vibration is needed to compact the material, the height of the inner cavity surface can be designed to be lower, so that the lowest point of the vibrator's movement will not touch the inner cavity surface. In this way, the hammer head does not directly transmit the knocking of the vibrator, but only the inertial vibration force. BRIEF DESCRIPTION OF THE DRAWINGS

The lower housing 14 is connected to the lower side of the upper housing 11.

[0025] The upper cover 11 has grooves 111 on both sides of the top, which can prevent the transmission part 20 from interfering with the side wall of the upper cover 11 when rotating. The bottom of the upper cover 11 has an upper ring 112 on the inner side, and an upper threaded area 113 on the outer side of the bottom.

[0026] The top of the lower cover shell 14 has a lower threaded area 141 , which cooperates with the upper threaded area 113 to achieve docking installation of the upper cover shell 11 and the lower cover shell 14 . The lower cover shell 14 has a lower ring 142 at the inner middle and lower part.

[0027] The transmission part 20 includes a rotating shaft 21, a crank 22, a connecting rod 23 and a pull rod 24. The rotating shaft 21 is hinged on the boss 13 and connected to the power source in the handle 12 to transmit rotation. The crank 22 is fixedly connected to the rotating shaft 21, the crank 22 is hinged to the connecting rod 23, the bottom of the connecting rod 23 is hinged to the pull rod 24, the top of the pull rod 24 has two ears 241, the two ears 241 are connected to the connecting rod 23, the bottom of the pull rod 24 has a paddle 242, and the paddle 242 is located inside the vibration part 30.

[0028] The vibrating part 30 includes a vibrator 31, a cover plate 32, an inner spring 33 and an outer spring 34. The vibrator 31 is a shell structure. The cover plate 32 is installed on the top of the vibrator 31. The cover plate 32 covers the two inner springs 33 and the paddle 242 inside the vibrator 31. The vibrator 31 has a vibrator boss 311 in the middle of the outer side. An outer spring 34 is respectively sleeved above and below the vibrator boss 311. The two inner springs 33 are respectively located on the upper side and the lower side of the paddle 242. The bottom of the vibrator 31 passes through the lower ring 142.

[0029] In detail, an inner spring 33 is located between the paddle 242 and the cover plate 32 , another inner spring 33 is located between the paddle 242 and the inner cavity bottom plate of the vibrator 31 , an outer spring 34 is located between the vibrator boss 311 and the upper ring 112 , and another outer spring 34 is located between the vibrator boss 311 and the lower ring 142 .

The inside of the hammering part 40 has an inner cavity surface 43, and the height of the inner cavity surface 43 is determined according to actual needs. If the required knocking force is large, the height of the inner cavity surface 43 can be designed to be high, so that the vibrator 31 can directly knock the inner cavity surface 43 every time it moves downward, that is, directly transmit the vibration of the vibrator 31. If the required knocking force is small, only the inertial moment of the vibration of the vibrator 31 is needed to compact the material, then the height of the inner cavity surface 43 can be designed to be low, so that the lowest point of the movement of the vibrator 31 will not touch the inner cavity surface 43. In this way, the hammering head 42 does not directly transmit the knocking of the vibrator 31, but only the inertial vibration force.

[0031] The working principle of the present invention is: the power source drives the crank 22 to rotate through the rotating shaft 21, and the connecting rod 23 swings accordingly, driving the pull rod 24 to move up and down, and the paddle 242 of the pull rod 24 pushes the two inner springs 33 to compress or open, and the vibrator 31 moves up and down accordingly. Under the joint action of the two outer springs 34, the vibrator 31 vibrates up and down. At this time, the vibration of the vibrator 31 is transmitted to the hammer part 40, and repeated knocking can be completed. The input speed of the power source is adjusted according to actual needs to obtain knocking responses of different frequencies.
