Description

Technical Field

[0001] This utility model relates to the field of cutting tool processing technology, specifically a welding filler for mining cutting tool processing. Background Technology

[0002] Mining cutters are core components of mining machinery such as coal mining machines and tunneling machines. They are mainly used for crushing coal and rock, directly affecting the equipment's production capacity, power consumption, and operational stability. Mining cutters use their sharp teeth to crush coal seams and rocks, cutting large pieces of coal and rock into smaller pieces for easier subsequent transportation and processing. When processing the cutters, a filling machine is used to fill the inside of the cutters with solder.

[0003] When using existing welding filler machines for mining cutting teeth, the function of these machines is to fill the inside of the cutting teeth. However, existing filler machines cannot adjust the position of the cutting teeth. When filling cutting teeth of different sizes, it is easy to cause problems such as misalignment between the filler and the filling inlet angle of the cutting teeth, which affects the processing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a welding filler for processing mining cutting teeth, so as to solve the problem mentioned in the background art that when filling cutting teeth of different sizes, the filling inlet angle of the filler and the cutting teeth cannot be aligned, which affects the processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding filler for machining mining cutting teeth, comprising:

[0006] The device body includes a worktable, a hydraulic rod is connected to one side of the top surface of the worktable, and a cutting tooth rod is provided on the other side of the top surface of the worktable;

[0007] An adjustment mechanism is rotatably connected to the outer surface of the bottom end of the cutting tooth rod. The adjustment mechanism includes a fixing screw sleeve, a positioning ring connected to the bottom end of the fixing screw sleeve, a positioning rod connected to the bottom end of the positioning ring, a support frame sleeved on the outer wall of the positioning rod, a fixing screw connected to the bottom surface of the positioning rod, and a nut rotatably connected to the outer surface of the bottom end of the fixing screw.

[0008] Preferably, the top end of the hydraulic rod can be connected and fixed to the filler machine, and the outer surface of the bottom end of the cutting rod is provided with threads, and the cutting rod and the fixing sleeve are rotatably connected by the threads.

[0009] Preferably, the top surface of the support frame has grooves on both sides, and the positioning rings are inserted into the grooves on both sides of the support frame.

[0010] Preferably, the bottom surface of the support frame has a slot, and one side of the workbench has a through slot. The bottom end of the fixing screw passes through the slot in the support frame and is inserted into the through slot in the workbench. The fixing screw and the nut are rotatably connected by a thread.

[0011] Preferably, a limiting structure is connected to one side of the support frame. The limiting structure includes a fixing frame, a control rod is inserted inside the top of the fixing frame, a limiting screw is connected to the bottom of the control rod, and a support spring is connected to one side of the top surface of the limiting screw.

[0012] Preferably, the top surface of the fixed frame has a movable groove, and the control rod is inserted into the movable groove of the fixed frame and movably connected to the fixed frame.

[0013] Preferably, there is no direct connection between the fixing frame and the support spring. Multiple sets of threaded grooves are provided on both sides of the inner wall of the through groove of the worktable, and the limiting screw is rotatably connected to the inside of the threaded groove of the worktable.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By rotating the bottom end of the cutting tooth rod to connect it to the inside of the fixing screw sleeve, and then inserting the bottom end of the fixing screw rod through the slot in the support frame into the through slot in the worktable, the positioning rings on both sides are inserted into the grooves in the support frame, thus positioning the positioning rod and the support frame. When adjusting the position of the cutting tooth rod, the fixing screw rod slides inside the through slot in the worktable. After the movement is completed, the nut is rotated to connect to the outer surface of the bottom end of the fixing screw rod to limit the fixing screw rod, thereby realizing the position adjustment of the cutting tooth rod and avoiding the problem of the filling inlet angle of the filler and the cutting tooth rod not being aligned, which would affect the processing efficiency.

[0016] 2. The support spring provides elastic support between the fixed frame and the limiting screw. When the support frame is limited, the angle of the control rod is adjusted so that the control rod drives the limiting screw to rotate. This causes the bottom end of the limiting screw to rotate and connect to the threaded groove in the worktable, thus limiting the position and angle of the support frame and achieving the limiting function of the cutting tooth rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A welding filler for machining mining cutting teeth, comprising:

[0026] The device body 1 includes a worktable 11. A hydraulic rod 12 is connected to one side of the top surface of the worktable 11, and a cutting rod 13 is provided on the other side of the top surface of the worktable 11. The surface material of the worktable 11 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application, so no further details are made.

[0027] An adjustment mechanism 2 is rotatably connected to the outer surface of the bottom end of the cutting tooth 13. The adjustment mechanism 2 includes a fixing screw sleeve 21, a positioning ring 22 connected to the bottom end of the fixing screw sleeve 21, a positioning rod 23 connected to the bottom end of the positioning ring 22, a support frame 24 sleeved on the outer wall of the positioning rod 23, a fixing screw 25 connected to the bottom surface of the positioning rod 23, and a nut 26 rotatably connected to the outer surface of the bottom end of the fixing screw 25.

[0028] Furthermore, the top of the hydraulic rod 12 can be connected and fixed to the filler machine, and the bottom outer surface of the cutting rod 13 is provided with threads. The cutting rod 13 and the fixing sleeve 21 are rotatably connected by the threads, so as to fix the bottom of the cutting rod 13 by connecting and fixing the cutting rod 13 and the fixing sleeve 21 through the threads, thereby fixing the position of the bottom of the cutting rod 13.

[0029] Furthermore, grooves are provided on both sides of the top surface of the support frame 24, and the positioning rings 22 are inserted into the grooves on both sides of the support frame 24, so as to position the two sides of the positioning rings 22 through the grooves on the support frame 24, thereby limiting the angle of the positioning rings 22.

[0030] Furthermore, a slot is provided on the bottom surface of the support frame 24, and a through slot is provided on one side of the worktable 11. The bottom end of the fixing screw 25 passes through the slot provided in the support frame 24 and is inserted into the through slot provided in the worktable 11. The fixing screw 25 and the nut 26 are connected by a thread, so as to connect and fix the fixing screw 25 and the nut 26 by the thread, thereby limiting the bottom end of the fixing screw 25.

[0031] Furthermore, a limiting structure 3 is connected to one side of the support frame 24. The limiting structure 3 includes a fixed frame 31. A control rod 32 is inserted inside the top of the fixed frame 31. A limiting screw 33 is connected to the bottom of the control rod 32. A support spring 34 is connected to one side of the top surface of the limiting screw 33. This achieves the effect of limiting the position and angle of the support frame 24, thereby achieving the limiting function of the cutting tooth rod 13.

[0032] Furthermore, a movable groove is provided on the top surface of the fixed frame 31, and the control rod 32 is inserted into the movable groove of the fixed frame 31 and movably connected to the fixed frame 31, so that the control rod 32 can be positioned through the movable groove of the fixed frame 31 and the control rod 32 can rotate inside the fixed frame 31.

[0033] Furthermore, there is no direct connection between the fixed frame 31 and the support spring 34. Multiple sets of threaded grooves are opened on both sides of the inner wall of the through groove of the worktable 11. The limiting screw 33 is rotatably connected to the inside of the threaded groove of the worktable 11, so that the limiting screw 33 is limited by the threaded groove of the worktable 11, and the limiting screw 33 restricts the position of the fixed frame 31.

[0034] Working principle: When adjusting the welding filler for mining cutting teeth, the bottom end of the cutting tooth rod 13 is rotated and connected to the inside of the fixing screw sleeve 21. Then, the bottom end of the fixing screw 25 is inserted through the slot in the support frame 24 and into the through slot in the worktable 11. The positioning ring 22 is inserted into the groove in the support frame 24 on both sides, positioning the positioning rod 23 and the support frame 24. When adjusting the position of the cutting tooth rod 13, the fixing screw 25 slides in the through slot in the worktable 11. After the movement is completed, the nut 26 is rotated and connected to the outer surface of the bottom end of the fixing screw 25 to limit the fixing screw 25, thereby realizing the position adjustment of the cutting tooth rod 13.

[0035] When the welding filler for mining cutting tooth processing is limited, the support spring 34 provides elastic support between the fixed frame 31 and the limiting screw 33. When the support frame 24 is limited, the angle of the control rod 32 is adjusted so that the control rod 32 drives the limiting screw 33 to rotate, so that the bottom end of the limiting screw 33 is rotatably connected to the threaded groove opened in the worktable 11, thereby limiting the position and angle of the support frame 24 and thus achieving the limiting function of the cutting tooth rod 13.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
