Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a ball mill liner cutting device. Background Technology

[0002] When the dimensions of the liner do not meet the installation requirements of the ball mill, the liner needs to be cut to ensure the installation accuracy of the liner and meet the needs of the ball mill.

[0003] The liner is cut using a cutting device. During the cutting process, the liner needs to be locked and positioned using a locking structure. The traditional locking structure uses locking clamps to lock the liner. Since the bottom of the liner is an outward-protruding arc structure, multiple locking clamps need to be set around the liner to lock and position it.

[0004] When multiple end faces of the liner need to be cut and adjusted, the positions of multiple locking clamps need to be adapted and adjusted to meet the cutting requirements. Traditional locking mechanisms are cumbersome to operate, and the locking effect is limited by the preload of the locking clamps. They are prone to loosening during the cutting process, which affects the quality of the finished product after the liner is cut. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a ball mill liner cutting device, which solves the problem of frequent locking during liner cutting and improves the efficiency and stability of liner cutting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ball mill liner cutting device includes a cutting platform for supporting the liner. A cutting device and a locking mechanism are mounted on the upper surface of the cutting platform. The locking mechanism includes a first locking device and a second locking device. The first locking device includes a first telescopic component and a first locking component installed at the first telescopic end of the first telescopic component. The first locking component locks the liner from the top through a mounting hole in the liner. The second locking device includes two symmetrically arranged sets of second locking components, which lock the liner from both sides of the bottom.

[0008] Preferably, the second locking assembly includes a second telescopic assembly, and the second telescopic end of the second telescopic assembly is fixedly connected to a second locking element.

[0009] Preferably, the second locking element is a locking block, and the surface of the locking block is arc-shaped.

[0010] Preferably, the second locking assembly includes a locking cam, which is connected to a rotating device via a control shaft.

[0011] Preferably, the first locking assembly includes a first locking rod fixedly connected to the first telescopic end, and a second locking rod is detachably fixedly connected to the side wall of the first locking rod.

[0012] Preferably, a pre-positioning device is installed on the upper end of the cutting platform, the pre-positioning device comprising a fixed first positioning component and a movable second positioning component.

[0013] Preferably, the second positioning component includes a positioning plate and an elastic telescopic rod fixedly connected to the positioning plate.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] Compared with the existing technology, this utility model does not require the traditional locking pliers to lock the liner plate. The liner plate is not obstructed by the locking pliers, and the cutting disc of the cutting device can continuously and smoothly cut the surface of the liner plate, which greatly improves the efficiency of cutting the liner plate. At the same time, the preload on both sides can be adjusted in real time during the cutting process to prevent the liner plate from shaking during the cutting process and ensure the stability of the liner plate cutting.

Detailed Implementation

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0024] See attached document Figure 1 - Appendix Figure 5 A ball mill liner cutting device includes a cutting platform 200 for supporting the liner 100. The upper surface of the cutting platform 200 is equipped with a cutting device and a locking mechanism. The locking mechanism locks and positions the liner 100 to ensure the stability of the liner 100 during the cutting process.

[0025] Traditional locking structures use locking clamps to lock the liner 100. Since the bottom of the liner 100 is an outwardly convex arc structure, multiple locking clamps are needed around the liner 100 to lock and position it. When multiple end faces of the liner 100 need to be cut and adjusted, the positions of multiple locking clamps need to be adapted to meet the cutting requirements. Traditional locking mechanisms are cumbersome to operate, and the locking effect is limited by the preload of the locking clamps. They are prone to loosening during the cutting process, affecting the quality of the finished product after the liner 100 is cut.

[0026] To address the aforementioned issues, the improved locking mechanism includes a first locking device 400 and a second locking device 500. The first locking device 400 includes a first telescopic assembly 410 and a first locking assembly 420 installed at the first telescopic end of the first telescopic assembly 410. The first locking assembly 420 passes through the mounting hole 110 of the liner 100 and locks the liner 100 from the top. The second locking device 500 includes two symmetrically arranged sets of second locking assemblies, which lock the liner 100 from both sides of the bottom.

[0027] During the locking operation, the liner 100 is placed at the predetermined cutting position. The liner 100 is arranged along the length of the second locking device 500. After the first locking component 420 passes through the liner 100, it locks and limits the liner 100 from the top, applying a downward preload to the top of the liner 100. The second locking components on both sides can lift the liner 100 from the bottom, applying an upward preload to the bottom of the liner 100. The liner 100 ensures the stability of the overall structure under the preload from both the top and bottom.

[0028] With the above structural design, there is no need for traditional locking clamps to lock the liner 100. The liner 100 is not obstructed circumferentially by the locking clamps, and the cutting disc of the cutting device can continuously and smoothly cut the surface of the liner 100, which greatly improves the cutting efficiency of the liner 100. At the same time, the preload on both sides can be adjusted in real time during the cutting process to prevent the liner 100 from shaking during the cutting process and ensure the stability of the cutting of the liner 100.

[0029] Please refer to the appendix for details. Figure 5 As a first preferred embodiment of the second locking assembly, the second locking assembly includes a second telescopic assembly 520, and a second locking element 510 is fixedly connected to the second telescopic end of the second telescopic assembly 520. The second locking element 510 is pushed upward by the second telescopic assembly 520 to abut against the liner 100, thereby applying an upward preload force to the liner 100. The two second locking elements 510 abut against each other upward, thereby pushing the liner 100 upward from both sides to ensure the stability of the liner 100 locking.

[0030] The second locking element 510 here is a locking block. The surface of the locking block is arc-shaped, and its arc shape matches the arc shape of the bottom of the liner 100 to increase the contact area at the bottom and ensure the clamping effect of both sides on the liner 100.

[0031] As a second preferred embodiment of the second locking assembly, the second locking assembly includes a locking cam, which is connected to a rotating device via a control shaft. The rotating device can be either electrically controlled or hydraulically controlled. By controlling the rotation of the locking cam, the protruding side of the locking cam can be pressed against the liner 100 from the bottom to ensure the stability of the liner 100 locking.

[0032] Please refer to the appendix for details. Figure 5Specifically, the first locking assembly 420 includes a first locking rod 421 fixedly connected to the first telescopic end, and a second locking rod 422 detachably fixedly connected to the side wall of the first locking rod 421. During the locking process, the first locking rod 421 passes through the mounting hole 110 on the surface of the liner 100, and then the second locking rod 422 is installed on the side wall of the first locking rod 421. The second locking rod 422 can apply a downward force to the liner 100 from the top to ensure the stability of the liner 100 locking. The first locking assembly 420 can also be selected from other forms of locking structure to lock the liner 100 from the top.

[0033] Furthermore, a pre-positioning device 300 is installed on the upper end of the cutting platform 200. The pre-positioning device 300 includes a fixed first positioning component 310 and a movable second positioning component 320. Specifically, the first positioning component 310 is detachably fixed to the upper end of the cutting platform 200 by bolts, and the second positioning component 320 is movably disposed relative to the upper end of the cutting platform 200. The first positioning component 310 and the second positioning component 320 can pre-position the middle liner 100 from both sides, so that the liner 100 can be in a predetermined position on the surface of the cutting platform 200. This facilitates the subsequent locking and positioning of the liner 100 by the first locking device 400 and the second locking device 500, thereby improving the efficiency of cutting the liner 100.

[0034] Specifically, the second positioning component 320 includes a positioning plate 322 and an elastic telescopic rod 321 fixedly connected to the positioning plate 322. During the pre-positioning process, with one side of the first positioning component 310 as a reference, the liner 100 is placed between the first positioning component 310 and the second positioning component 320. The liner 100 is pressed down on the side close to the second positioning component 320, so that the liner 100 can be elastically clamped and limited between the first positioning component 310 and the second positioning component 320, thus ensuring the stability of the liner 100's positioning.

[0035] The top of the positioning plate 322 is tilted outward, which can guide the liner 100 during the pressing process, so that the liner 100 can smoothly enter between the first positioning component 310 and the second positioning component 320, further improving the pre-positioning efficiency and cutting efficiency of the liner 100.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
