Description

Technical Field

[0001] This utility model relates to the field of vertical mill technology, specifically to a vertical mill rocker arm connecting rod structure that facilitates amplitude adjustment. Background Technology

[0002] The rocker arm is an important component of the vertical mill. Its main task is to transmit the pressure of the hydraulic cylinder to the grinding roller, so that it is converted into grinding force on the material bed.

[0003] For example, the prior art disclosure number CN220680470U provides a vertical mill rocker arm linkage structure that is easy to adjust the amplitude. This utility model solves the problem that the rocker arm swing amplitude of the existing single rocker arm linkage mechanism for vertical mills is not easy to adjust, which leads to the limitation of its use.

[0004] Based on actual usage, the aforementioned prior art mainly adjusts its length and amplitude by sliding the first slide rod and the second slide rod. However, it was found in use that after determining the working length of the first slide rod and the second slide rod, it is necessary to rotate two sets of positioning bolts to make them engage with the positioning teeth on the telescopic rod. During the adjustment process, it is necessary to repeatedly rotate the two sets of positioning bolts, which is cumbersome and inefficient. Therefore, based on actual usage, we have improved the aforementioned prior art. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0006] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A vertical mill rocker arm linkage structure with adjustable amplitude includes a mounting plate, on which a rocker arm and a guide rail are mounted. A sliding pin is slidably connected inside the guide rail. A sliding rod is mounted on one end of the sliding pin near the mounting plate. A rotating rod is connected to the rocker arm via a rotating shaft, and the sliding rod is slidably connected to the inner cavity of the rotating rod. Multiple sets of positioning holes are provided on the sliding rod. A mounting box is provided on the outer wall of the rotating rod, and a positioning pin that matches the positioning holes is slidably connected inside the mounting box. A locking groove is provided on the positioning pin, and two sets of positioning components that fix the locking groove are provided inside the mounting box.

[0009] Furthermore, the outer wall of the rotating rod has a through opening that matches the positioning sliding pin, and the through opening communicates with the inner cavity of the mounting box.

[0010] Furthermore, the positioning component includes an operating rod slidably connected to the side wall of the mounting box, and an auxiliary sliding plate is connected to the bottom of the operating rod, the auxiliary sliding plate being slidably connected to the inner wall of the mounting box.

[0011] Furthermore: the end of the auxiliary slide plate near the positioning pin is connected to a positioning block that matches the locking groove, and the outer wall of the operating rod is fitted with a compression spring, which is located between the outer side of the auxiliary slide plate and the inner wall of the mounting box.

[0012] Furthermore, both sets of operating levers and positioning pins are connected to pull rings at the top, and the handheld end of the pull ring is covered with an anti-slip rubber sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention allows the auxiliary slide plate to slide by pulling two sets of operating rods on the positioning component. With the elasticity of the compression spring, the positioning block can connect or disengage with the locking groove on the positioning pin, thus fixing and releasing the positioning pin. The sliding positioning pin can connect with the corresponding positioning hole, realizing the quick fixing of the rotating rod and sliding rod after the length is adjusted. This replaces the traditional method of using two sets of positioning bolts for fixing, eliminating the need for repeated rotation and improving work efficiency.

[0025] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1:

[0027] Please see Figure 1-3 This utility model provides a technical solution: a vertical mill rocker arm linkage structure that is easy to adjust the amplitude, including a mounting plate 1, a rocker arm 2 and a guide rail 3 mounted on the mounting plate 1, a sliding pin 4 slidably connected inside the guide rail 3, a sliding rod 6 mounted on one end of the sliding pin 4 near the mounting plate 1, a rotating rod 5 connected to the rocker arm 2 via a rotating shaft, and the sliding rod 6 slidably connected to the inner cavity of the rotating rod 5, the sliding rod 6 having multiple sets of positioning holes 7, a mounting box 8 provided on the outer wall of the rotating rod 5, and a positioning pin 9 adapted to the positioning holes 7 slidably connected inside the mounting box 8, the positioning pin 9 having a locking groove 15, and two sets of positioning components for fixing the locking groove 15 inside the mounting box 8.

[0028] Mounting plate 1 is also equipped with a bending rod, a deflector rod, and a rotating component, which are not shown in the figure. This is the existing structure and technology, and the specific principle will not be explained here. Mounting box 8 is fixedly connected to the outer wall of rotating rod 5. When adjusting the working length between rotating rod 5 and sliding rod 6, the positioning component does not fix the locking groove 15. At this time, the position of the positioning pin 9 is unrestricted and pulled outward, and the sliding rod 6 can slide in the inner cavity of rotating rod 5 until the length of both reaches the required working length. At this time, a set of positioning holes 7 aligns with the positioning pin 9, and the positioning pin 9 is moved down to connect with the corresponding positioning hole 7. Then, the positioning component fixes the locking groove 15, that is, fixes the position of the positioning pin 9 and prevents it from sliding outward. Similarly, when it is necessary to adjust the working length of rotating rod 5 and sliding rod 6, the positioning component does not limit the locking groove 15, the positioning pin 9 slides out of the positioning hole 7, and the sliding rod 6 can move in the rotating rod 5 to realize the length adjustment. This replaces the traditional use of two sets of positioning bolts for fixing, eliminates the need for repeated rotation, and improves work efficiency.

[0029] Preferably, the outer wall of the rotating rod 5 has a through opening 11 that matches the positioning sliding pin 9, and the through opening 11 communicates with the inner cavity of the mounting box 8.

[0030] Preferably, the positioning component includes an operating rod 10 slidably connected to the side wall of the mounting box 8, and an auxiliary slide plate 12 is connected to the bottom of the operating rod 10. The auxiliary slide plate 12 is slidably connected to the inner wall of the mounting box 8; the operating rod 10 and the auxiliary slide plate 12 are fixedly connected.

[0031] Preferably, the auxiliary slide plate 12 is connected to a positioning block 14 that is compatible with the locking groove 15 at one end near the positioning pin 9, and the outer wall of the operating rod 10 is fitted with a compression spring 13, and the compression spring 13 is located between the outer side of the auxiliary slide plate 12 and the inner wall of the mounting box 8.

[0032] The auxiliary slide plate 12 and the positioning block 14 are fixedly connected. When it is necessary to adjust the length of the rotating rod 5 and the sliding rod 6, both sets of operating rods 10 are pulled outward. After the two sets of auxiliary slide plates 12 are subjected to force, they move in opposite directions. At this time, the compression spring 13 is in a compressed state, the positioning block 14 disengages from the locking groove 15, and the positioning pin 9 can slide out of the corresponding positioning hole 7. When the positioning pin 9 is connected to the corresponding positioning hole 7, the locking groove 15 is aligned with the corresponding positioning block 14. When the operating rod 10 is released, the compressed spring 13 will automatically return to its original position, and the adjacent auxiliary slide plates 12 move in opposite directions until the two sets of positioning blocks 14 are connected in the corresponding locking groove 15, which fixes the position of the positioning pin 9 and prevents it from sliding out, thus improving the stability of the positioning pin 9 when fixing the positioning hole 7.

[0033] Example 2:

[0034] Reference Figure 3This embodiment differs from the first embodiment in that: the tops of both sets of operating rods 10 and positioning sliding pins 9 are connected to pull rings, and the handheld end of the pull ring is covered with an anti-slip rubber sleeve; the pull ring facilitates the pulling of the operating rods 10 and positioning sliding pins 9, and the anti-slip rubber sleeve plays an anti-slip role, preventing the hand from slipping off when holding the pull ring.

[0035] It should be noted that the electrical component of this utility model is used to organize the wire harness during operation, and will not cause the wire harness to become tangled.

[0036] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
