Technical Field

[0001] The present application relates to a servo spreader cutter head, and in particular to a bracket-integrated servo spreader cutter head. Background Art

[0002] The cutter head can convert axial displacement into radial displacement during high-speed rotation, thereby realizing the processing of outer circles, inner holes, end faces, internal and external threads, and internal and external rotary surfaces of parts. Different tools can be adjusted and replaced according to different processing requirements.

[0003] However, most of the current servo motors of the spreader head are installed on the housing through a motor mounting bracket or a motor stud, and can only be installed on one side according to the designed position, and cannot be selectively installed on the left or right side. Secondly, the transmission structure of the spreader head is installed inside the housing. Once maintenance is required, the housing must be disassembled for maintenance, which increases the difficulty of maintenance.

[0004] Therefore, there is an urgent need for a bracket-integrated servo spreader cutter head to solve the problems existing in the prior art. Utility Model Content

Compared with the prior art, the present application combines the motor mounting bracket and the like on the vertical cover, and has two motor mounting positions, so that the servo motor mounting position can be flexibly adjusted according to customer needs.

[0014] 2. Compared with the prior art, the present application exposes the horizontal displacement transmission structure, thereby facilitating maintenance of the horizontal displacement transmission structure, especially operations such as adding lubricating oil.

[0015] Furthermore, a plurality of threaded holes are provided on the top of the vertical cover, and the threaded holes are at least two groups symmetrical on the left and right, thus providing a basis for expanding parts.

[0016] Furthermore, the servo motor is mounted on the vertical cover shell through the motor connecting plate and the connecting piece, and the motor mounting position is closed by the motor connecting plate, and the motor mounting position is closed by the closing plate on the other side of the vertical cover shell.

The connecting seat is respectively connected to the guide copper sleeve, the slider of the linear guide rail and the transmission rod, so that the connecting seat can move back and forth along the length direction of the linear guide rail.

[0020] Furthermore, the rotation transmission structure includes two pulleys and a synchronous belt, wherein the two pulleys are respectively connected to the output end of the servo motor and the transmission rod, and the synchronous belt connects the two pulleys. The pulleys and the transmission rod are connected by a keyway, and the side of the pulley is limited by a limit block for axial movement, so that the movement of the transmission rod will not cause the pulley to move.

Therefore, the above terms should not be understood as limiting the present application.

[0030] like Figure 1-3 As shown, the bracket integrated servo blade head includes:

[0031] Spreading head 1;

[0032] In this embodiment, the spreading cutter head 1 is a prior art, and its structure and principle will not be described in detail here.

[0033] The housing 2 includes a vertical cover 21 and a horizontal cover 22 vertically connected to the bottom of the vertical cover 21. Both sides of the top of the vertical cover 21 are provided with motor mounting positions. The horizontal cover 22 is provided with an opening 221 for exposing the horizontal displacement transmission structure 7.

[0034] In this embodiment, the top of the vertical cover 21 is provided with a plurality of threaded holes, and the threaded holes are at least two groups of left-right symmetry. The servo motor 4 is installed on the vertical cover 21 through the motor connecting plate 3 and the connecting piece, and the motor installation position is closed by the motor connecting plate 3. The other side of the vertical cover 21 is closed by the closing plate 215. The top of the vertical cover 21 is used to position the height of the motor connecting plate 3 through the positioning block 212 and the positioning stud 213 on the positioning block 212, and the positioning block 212 is installed on the threaded hole through the connecting piece. The top of the motor connecting plate 3 is provided with a screw hole that matches the positioning stud 213. In this way, the height of the motor connecting plate 3 can be conveniently positioned, and the positioning block 212 can be disassembled and adjusted at will. No matter which side the servo motor 4 is installed on, it can be positioned by the positioning block 212.

[0035] Preferably, in order to facilitate the hoisting, painting and handling operations of the housing 2, a pull ring 214 is further included, which is screwed with the threaded hole. The pull ring 214 can facilitate the hoisting operation of the housing 2, and the pull ring 214 can be removed when not in use.

[0036] The servo motor 4 is mounted on one side of the vertical cover 21 through the motor mounting hole group, and is drivingly connected to the transmission rod 5 through the rotation transmission structure 8, so as to drive the transmission rod 5 to rotate;

[0037] In this embodiment, the rotation transmission structure 8 includes two pulleys 81 and a synchronous belt 82. The two pulleys 81 are respectively connected to the output end of the servo motor 4 and the transmission rod 5, and the synchronous belt 82 connects the two pulleys 81. The pulleys 81 and the transmission rod 5 are connected by a keyway, and the side of the pulley 81 is limited by a limit block 83 to limit axial movement, so that the movement of the transmission rod 5 will not cause the pulley 81 to move.

[0038] The transmission rod 5 is installed inside the horizontal cover 22, one end of which is connected to the ball screw 6 through the horizontal displacement transmission structure 7, and the other end is connected to the spreader head 1; wherein, the transmission rod 5 includes a rod core and a sleeve outside the rod core, the sleeve is connected to the pulley 5 through a keyway, and the other end is connected to the spreader head 1, so that the other end of the rod core of the transmission rod 5 is connected to the connecting seat 71 to realize the movement of the rod core in the sleeve.

[0039] The ball screw 6 has one end rotatably connected to the inside of the horizontal cover 22, and the other end is drivingly connected to the drive motor 9, and the middle area is connected to the horizontal displacement transmission structure 7 through the guide copper sleeve 73;

[0040] In this embodiment, the horizontal displacement transmission structure 7 includes a connecting seat 71 and a linear guide rail 72 arranged parallel to the transmission rod 5. The connecting seat 71 is respectively connected to a guide copper sleeve 73, a slider of the linear guide rail 72 and the transmission rod 5, so that the connecting seat 71 can move back and forth along the length direction of the linear guide rail 72. In this way, the connecting seat 71 can drive the transmission rod 5 to move horizontally.

[0041] Preferably, the guide copper sleeve 73 is a graphite copper sleeve. The graphite copper sleeve has the advantage of high precision and can achieve better transmission guide accuracy. The graphite copper sleeve is embedded with solid lubricant (such as graphite). During use, due to the effect of friction, the graphite will gradually transfer to the contact surface to form a lubricating film, thereby greatly reducing the metal-to-metal direct contact between the shaft and the bearing, reducing wear and friction coefficient. Graphite itself has good wear resistance and chemical stability, so the graphite copper sleeve can effectively resist wear under high load, and is not afraid of corrosion and erosion by media such as water and acid, and is suitable for working in harsh environments.

[0042] The driving motor 9 is installed at one end of the horizontal cover 22 away from the cutting head 1 through a connecting piece, and is used to drive the ball screw 6 to rotate.

[0043] Preferably, the drive motor 9 is connected to the ball screw 6 through a plum blossom coupling. As an elastic coupling, the plum blossom-shaped elastic body of the plum blossom coupling has good elasticity, which can effectively buffer and reduce the impact, vibration and torsional vibration generated by the motor during operation, ensuring the stability and smoothness of power transmission. It also has the advantages of compensating for phase shift, protecting the ball screw, no need for lubrication, and being compact and lightweight.

[0044] Preferably, a detachably connected maintenance plate 222 is provided at the position of the connection between the drive motor 9 and the ball screw 6 on the horizontal cover 22. This can facilitate the maintenance operation of the connection between the drive motor 9 and the ball screw 6, that is, it can also facilitate the disassembly and assembly operation of the drive motor 9.

[0045] The parts not described in detail in this application are prior art, so this application does not describe them in detail.

[0046] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0047] Although the present invention uses more terms such as the blade head 1, housing 2, motor connecting plate 3, servo motor 4, transmission rod 5, ball screw 6, horizontal displacement transmission structure 7, rotation transmission structure 8, drive motor 9, vertical cover 21, threaded hole, positioning block 212, positioning stud 213, pull ring 214, closing plate 215, horizontal cover 22, opening 221, maintenance plate 222, connecting seat 71, linear guide 72, guide copper sleeve 73, pulley 81, synchronous belt 82, etc., it does not exclude the possibility of using other terms. The use of these terms is only for the purpose of more conveniently describing and explaining the essence of the present application; interpreting them as any additional restrictions is contrary to the spirit of the present application.

[0048] The present application is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of this application. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present application.
