Description

Technical field

[0001] The utility model relates to the technical field of stone processing equipment, in particular to a swing rod device of a saw frame. [Background Technology]

[0002] In the processing of some large stones, a frame saw is often required; a frame saw is a device that installs dozens to hundreds of saw blades on a reciprocating saw frame to saw the rough material into rough boards, such as the Chinese utility model patent with application number CN202022283177.0, which discloses a zipper frame saw for sawing stone thin plates.

[0003] However, existing frame saws are typically only suitable for cutting marble and are incapable of cutting super-hard stone materials such as granite. This is because diamond blades are used for cutting, and the frame of existing frame saws drives the saw blade in horizontal motion to achieve a flat cut. Cutting super-hard stone materials such as granite requires extremely sharp blades, which are subject to significant wear and tear, resulting in high costs and practically meaningless. In light of these issues, the inventors of this case conducted in-depth research on this issue, leading to the creation of this case. [Utility Model Content]

[0004] The technical problem to be solved by the utility model is to provide a swing arm device for a saw frame, which solves the problem that the existing frame saw can usually only cut marble among stones, but cannot be used to cut super-hard stones such as granite.

[0005] The utility model is realized as follows: a swing arm device of a saw frame comprises a support frame and a saw frame body movably arranged on the support frame; swing arm assemblies are arranged at both ends of the saw frame body;

[0006] Each of the swing arm assemblies includes a first connecting rod, a second connecting rod, a swing arm, and a first connecting shaft. The length of the first connecting rod is greater than that of the second connecting rod. The two swing arms on the same side are formed with a first connecting portion at ends close to each other, and a second connecting portion is formed at ends away from each other.

[0007] The middle of the swing arm is connected to the saw frame body through a first connecting shaft, the upper end of the first connecting rod is rotatably connected to the first connecting part, the lower end of the first connecting rod is rotatably connected to the support frame, the lower end of the second connecting rod is rotatably connected to the second connecting part, and the upper end of the second connecting rod is rotatably connected to the support frame; a parallel line of the first connecting rod is drawn through the rotation fulcrum of the second connecting part, and the second connecting rod is inclined relative to the parallel line toward the side close to the first connecting part.

[0008] Furthermore, an outer box body is provided on the support frame at a position corresponding to each rocker arm assembly, and the rocker arm assembly is installed in the outer box body; the outer box body is formed with a strip movable groove along the horizontal direction on the side facing the saw frame body, and the first connecting axis passes through the strip movable groove and is connected to the saw frame body.

[0009] Furthermore, a movable opening is formed on the top of the outer box body, and a first support seat is provided on the top surface of the outer box body at a position corresponding to the movable opening. The upper end of the second connecting rod is rotatably connected to the first support seat through a second connecting shaft.

[0010] Furthermore, a second support seat is provided at the inner bottom of the outer box body, and the lower end of the first connecting rod is rotatably connected to the second support seat via a third connecting shaft.

[0011] Furthermore, the swing arm includes a first connecting plate, a second connecting plate, and a hollow connecting column connected between the first connecting plate and the second connecting plate; one end of the first connecting shaft is disposed in the hollow connecting column;

[0012] The upper end of the first connecting rod is rotatably connected between the first connecting plate and one end of the second connecting plate through a fourth connecting shaft, and the lower end of the second connecting rod is rotatably connected between the first connecting plate and the other end of the second connecting plate through a fifth connecting shaft.

[0013] Furthermore, reinforcing ribs are provided between the first connecting plate, the second connecting plate and the hollow connecting column.

[0014] Furthermore, the saw frame body includes a front frame plate, a rear frame plate and two side frame bars connected between the front frame plate and the rear frame plate; the two side frame bars are movably assembled and connected to the support frame.

[0015] Furthermore, a third support base is provided at the bottom of the front frame plate and the rear frame plate, and the first connecting shaft is rotatably connected to the third support base.

[0016] Furthermore, it also includes a driving mechanism, which is connected to one end of the saw frame body and drives the saw frame body to reciprocate.

[0017] By adopting the technical solution of the present invention, at least the following beneficial effects are achieved: a rocker arm assembly is set at both ends of both sides of the saw frame body, and the length of the first connecting rod in the rocker arm assembly is cleverly designed to be greater than the length of the second connecting rod, and a parallel line of the first connecting rod is made through the rotation fulcrum of the second connecting part of the rocker arm, and the second connecting rod is tilted to the side close to the first connecting part of the rocker arm relative to the parallel line. By adopting the above structural design, during the actual cutting process, the saw frame body will swing under the action of the rocker arm assembly and form a certain inclination, that is, the entire movement trajectory of the saw frame body is an arc trajectory, rather than a horizontal straight line trajectory, so that the saw frame body can drive the saw blade to perform line segment cutting on the stone (such as granite, etc.), and the pressure during the actual cutting will be concentrated on the cutting line segment. Therefore, when the diamond cutter head is made relatively not so sharp, it can not only meet the cutting requirements of super hard stone such as granite, but also ensure that the service life of the diamond cutter head is within a reasonable range, thereby reducing costs.

Therefore, features defined as "first," "second," and the like may explicitly or implicitly include one or more of such features.

[0034] See also Figures 1 to 6 As shown, a preferred embodiment of a swing arm device for a saw frame of the present invention comprises a support frame 1 and a saw frame body 2 movably arranged on the support frame 1. During operation, the saw frame body 2 can move relative to the support frame 1 to achieve cutting. Both sides of the saw frame body 2 are provided with swing arm assemblies 3 at both ends.

[0035] Please refer to Figure 5 As shown, each of the swing link assemblies 3 includes a first connecting rod 31, a second connecting rod 32, a swing arm 33, and a first connecting shaft 34. The length of the first connecting rod 31 is greater than that of the second connecting rod 32. The two swing arms 33 on the same side are formed with a first connecting portion 331 at their ends close to each other, and a second connecting portion 332 at their ends away from each other.

[0036] The middle of the swing arm 33 is connected to the saw frame body 2 through the first connecting shaft 34, so that the rocker assembly 3 can move in conjunction with the saw frame body 2, the upper end of the first connecting rod 31 is rotatably connected to the first connecting part 331, the lower end of the first connecting rod 31 is rotatably connected to the support frame 1, the lower end of the second connecting rod 32 is rotatably connected to the second connecting part 332, and the upper end of the second connecting rod 32 is rotatably connected to the support frame 1; a parallel line to the first connecting rod 31 is drawn through the rotation fulcrum of the second connecting part 332, and the second connecting rod 32 is inclined relative to the parallel line toward the side close to the first connecting part 331, that is, the second connecting rods 32 of the two rocker assembly 3 on the same side are inclined relative to the parallel line toward opposite directions.

[0037] The utility model adopts a method of setting a swing arm assembly 3 at both ends of both sides of the saw frame body 2, and cleverly designs that the length of the first connecting rod 31 in the swing arm assembly 3 is greater than the length of the second connecting rod 32, and a parallel line is drawn through the rotation fulcrum of the second connecting portion 332 of the swing arm 33 to the first connecting rod 31, and the second connecting rod 32 is inclined to the side of the first connecting portion 331 close to the swing arm 33 relative to the parallel line. By adopting the above structural design, during the actual cutting process, the saw frame body 2 will swing under the action of the swing arm assembly 3 and form a certain inclination, that is, the entire movement trajectory of the saw frame body 2 is an arc trajectory, rather than a horizontal straight line trajectory, so that the saw frame body 2 can drive the saw blade 5 to cut the stone (such as granite, etc.) in line segments, and the pressure during the actual cutting will be concentrated on the cutting line segment. Therefore, the diamond cutter head can be made relatively not too sharp, while meeting the cutting requirements of super-hard stones such as granite and ensuring that the service life of the diamond cutter head is within a reasonable range, thereby reducing costs.

[0038] In some embodiments of the present invention, please refer to Figure 2 As shown, an outer box body 4 is provided on the support frame 1 at the position corresponding to each rocker assembly 3, and the rocker assembly 3 is installed in the outer box body 4.

The first connecting shaft 34 passes through the strip movable groove 41 and is connected to the saw frame body 2. When working, the first connecting shaft 34 can move along the strip movable groove 41, and the size of the strip movable groove 41 is larger than the size of the first connecting shaft 34 to ensure that the first connecting shaft 34 can drive the saw frame body 2 to tilt slightly.

[0040] During the specific implementation of the present invention, a movable opening 42 is formed on the top of the outer box body 4, and a first support seat 43 is provided on the top surface of the outer box body 4 at a position corresponding to the movable opening 42. The upper end of the second connecting rod 32 is rotatably connected to the first support seat 43 through a second connecting shaft 35, so that the second connecting rod 32 can rotate and swing.
