Description

Technical Field

[0001] This utility model relates to the technical field of gravure roller grinding machines, and in particular to a high-speed grinding head with an electric spindle. Background Technology

[0002] Currently, the grinding machines used by various plate-making factories have grinding heads rotated by servo motors, which have limited speeds, reaching only 500-600 r / min. The speed cannot be higher. This is due to two reasons: one is the problem with the motor itself, and the other is that the mechanical structure of the grinding head cannot meet the requirements, which will cause vibration and fail to meet the usage requirements.

[0003] A utility model application with publication number CN216463465U discloses an electric spindle grinding device, which includes a machine base, a product mounting mechanism installed within the machine base, and a grinding mechanism for grinding the product. The front end face of the machine base is movably provided with a double door. The product mounting mechanism includes a rotary drive assembly and a product positioning shaft driven and connected to the rotary drive assembly, with the product mounted at one end of the product positioning shaft. The grinding mechanism includes a transverse drive assembly, a front and rear drive assembly, and a grinding assembly connected to the front and rear drive assembly.

[0004] In the above scheme, during grinding and polishing, fine particles from the surface of the gravure roller will splash outwards, damaging the structure of the grinding machine and reducing its service life. Utility Model Content

[0005] The purpose of this invention is to provide a high-speed grinding head for electric spindles to address the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A high-speed electric spindle grinding head includes a grinding mechanism capable of moving along the length of the flat-head grinding machine. The grinding mechanism includes a longitudinally arranged transverse drive seat, on which an inclined inward motor module and a guide cover for mounting the motor module are mounted. The guide cover is provided with a first mounting space and a second mounting space separated from each other. The motor module includes a drive assembly and a grinding head mounted on the drive end of the drive assembly. The grinding head is located in the second mounting space. The bottom of the second mounting space is provided with a first side baffle and a second side baffle to prevent fine debris from splashing outward.

[0008] Furthermore, the guide cover is provided with a height adjustment mechanism for adjusting the height of the second side baffle. The height adjustment mechanism includes a back connecting post connected to the back of the second side baffle, and the guide cover is formed with a longitudinal sliding groove for guiding the back connecting post to move.

[0009] Furthermore: A mounting plate is provided at the top of the longitudinal sliding groove, and a longitudinal lifting cylinder is provided on the mounting plate. The drive end of the longitudinal lifting cylinder is connected to the back connecting column.

[0010] Furthermore: a motor frame is provided in the first installation space, and the drive assembly includes a motor body mounted on the motor frame, with a motor drive shaft mounted on the drive end of the motor body; a drive hole for the motor drive shaft to pass through is provided between the first installation space and the second installation space, and the grinding head is mounted on the motor drive shaft.

[0011] Furthermore: a first drive seat inclined inward is mounted on the transverse drive seat, a second drive seat is slidably mounted on the first drive seat longitudinally, and the motor module is slidably mounted on the second drive seat.

[0012] Furthermore: a first linear module is arranged along the length direction of the first drive seat, the drive end of the first linear module is connected to the second drive seat, a first linear rail is arranged beside the first linear module, a first linear sliding seat is slidably installed on the first linear rail, and the first linear sliding seat is connected to the second drive seat.

[0013] Furthermore: the second drive seat is provided with a second linear track along its length, the second linear track is slidably mounted with a second linear slide seat, the motor frame is mounted on the second linear slide seat, and the second drive seat is provided with an elastic drive component that contacts the motor frame.

[0014] Furthermore: the elastic drive component includes a longitudinally arranged elastic lifting cylinder, a drive block is provided on the top of the motor frame that is longitudinally aligned with the drive end of the elastic lifting cylinder, an elastic block is installed on the second drive seat, a compression spring is installed on the back of the elastic block, and the rear end of the compression spring is connected to the drive block of the motor frame.

[0015] Furthermore: a drive sleeve through which the motor drive shaft slides is installed in the drive hole.

[0016] The beneficial effects of this utility model are as follows: The motor module is installed through the first installation space and the second installation space, which separates the grinding head from the drive assembly. During grinding, the fine debris splashed from the gravure roller is less likely to enter the drive assembly, thus preventing transmission failure of the drive assembly. The bottom of the second installation space is provided with a first side baffle and a second side baffle to prevent fine debris from splashing outwards. This can reduce the wear and tear on the body structure of the grinding machine and extend its service life. Attached Figure Description

[0032] The present invention will now be described in detail with reference to the accompanying drawings.

[0033] like Figure 1-3 As shown, a high-speed electric spindle grinding head includes a grinding mechanism 1 that can move along the length of the flat-head grinding machine. The grinding mechanism 1 includes a longitudinally arranged transverse drive seat 11, on which a motor module 3 inclined inward and a guide cover 12 for mounting the motor module 3 are mounted. The guide cover 12 is provided with a first mounting space 13 and a second mounting space 14 separated from each other. The motor module 3 includes a drive assembly and a grinding head 34 mounted on the drive end of the drive assembly. The grinding head 34 is disposed in the second mounting space 14. The bottom of the second mounting space 14 is provided with a first side baffle 15 and a second side baffle 41 to prevent fine debris from splashing outward.

[0034] The motor module 3 is installed through the first mounting space 13 and the second mounting space 14, separating the grinding head 34 from the drive assembly. During grinding, fine debris splashed from the gravure roller is less likely to enter the drive assembly, preventing transmission failure of the drive assembly. The bottom of the second mounting space 14 is provided with a first side baffle 15 and a second side baffle 41 to prevent fine debris from splashing outwards; this can reduce wear on the body structure of the grinder and extend its service life.

[0035] Specifically, the guide cover 12 is equipped with a height adjustment mechanism 4 for adjusting the height of the second side baffle 41. The height adjustment mechanism 4 includes a back connecting post 42 connected to the back of the second side baffle 41, and the guide cover 12 is formed with a longitudinal sliding groove 43 for guiding the back connecting post 42 to move. The back connecting post 42 can move longitudinally through the longitudinal sliding groove 43 to adjust the height of the second side baffle 41, thereby adjusting the area of ​​the shield. During grinding, the area of ​​the shield is adjustable.

[0036] Preferably, a mounting plate 44 is provided at the top of the longitudinal sliding groove 43, and a longitudinal lifting cylinder 45 is provided on the mounting plate 44. The driving end of the longitudinal lifting cylinder 45 is connected to the back connecting column. Under the drive of the longitudinal lifting cylinder 45, the back connecting column 42 can move along the longitudinal sliding groove 43 to realize the height adjustment of the second side baffle 41.

[0037] The first installation space 13 is provided with a motor frame 31, and the drive assembly includes a motor body 32 mounted on the motor frame 31. A motor drive shaft 33 is mounted on the drive end of the motor body 32. The first installation space 13 and the second installation space 14 are separated by a partition 16. The partition 16 is provided with a drive hole 17 through which the motor drive shaft 33 passes. The grinding head 34 is mounted on the motor drive shaft 33. Under the action of the partition 16, the motor body 32 and the grinding head 34 mounted on the motor drive shaft 33 are separated, which can effectively reduce the situation where splashed fine particles enter the drive assembly and separate the drive module from the grinding head 34.

[0038] Furthermore, a drive sleeve 18 is installed in the drive hole 17 through which the motor drive shaft 33 slides. When the height of the motor module 3 needs to be adjusted, the drive sleeve 18 and the motor drive shaft 33 can slide together, so that the height of the grinding head 34 can be adjusted, and the gravure rollers with different outer diameters can be ground and polished, further improving its practicality.

[0039] In one embodiment, a first drive seat 2 inclined inward is mounted on a transverse drive seat 11, and a second drive seat 21 is slidably mounted on the first drive seat 2 longitudinally. A motor module 3 is slidably mounted on the second drive seat 21. A first linear module 22 is arranged along the length of the first drive seat 2, and the driving end of the first linear module 22 is connected to the second drive seat 21. A first linear track 23 is arranged beside the first linear module 22, and a first linear sliding seat 24 is slidably mounted on the first linear track 23, which is connected to the second drive seat 21. Driven by the first linear module 22, the second drive seat 21 can move along the first linear track 23 via the first linear sliding seat 24, thereby adjusting the height of the second drive seat 21. The height of the motor module 3 mounted on the second drive seat 21 is adjustable, allowing for grinding and polishing of gravure rollers of different sizes.

[0040] Furthermore, the second drive seat 21 is provided with a second linear track 25 along its length, and a second linear sliding seat 26 is slidably mounted on the second linear track 25. The motor frame 31 is mounted on the second linear sliding seat 26. The second drive seat 21 is provided with an elastic drive member 35 that contacts the motor frame 31. When polishing, the grinding head 34 contacts the surface of the gravure roller. Driven by the elastic drive member 35, the motor module 3 located on the second drive seat 21 can move downward along the second linear track 25 through the second linear sliding seat 26, so that the grinding head 34 can elastically contact the gravure roller. When in contact, it has a buffering effect, further improving the precision of polishing.

[0041] Specifically, the elastic drive component 35 includes a longitudinally arranged elastic lifting cylinder 36, a drive block 37 that is longitudinally aligned with the drive end of the elastic lifting cylinder 36 on the top of the motor frame 31, an elastic block 38 installed on the second drive seat 21, a compression spring 39 installed on the back of the elastic block 38, and the rear end of the compression spring 39 connected to the drive block 37 of the motor frame 31. During grinding, the drive end of the elastic lifting cylinder 36 is pressed down, which will drive the drive block 37 installed on the motor frame 31 to press down. At this time, the compression spring 39 installed on the elastic block 38 will be compressed. When the compression spring 39 is compressed, the grinding head 34 has a buffering effect when it contacts the gravure roller, which can ensure that the grinding head 34 is always in contact with the gravure roller.

[0042] It should be noted that the guide cover 12 is installed on the horizontal drive seat 11 and is in a fixed state. When the motor module 3 moves longitudinally, the motor drive shaft 33 of the motor module 3 will slide and engage with the drive sleeve 18 of the drive hole 17, so that the bottom grinding head 34 can move longitudinally with slight adjustment and will not collide with the partition 16, thus ensuring stable grinding and polishing.

[0043] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0044] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
