Description

Technical Field

[0001] The utility model relates to the technical field of saw blade processing, in particular to a saw blade tooth grinding device. Background Art

[0002] A saw consists of a tough and toothed saw blade tensioned in a frame and is used for cutting metals, other shaped materials, etc. After being used for a period of time, the saw will become blunt, resulting in an unsmooth cutting phenomenon. The sawing surface formed on the workpiece is very rough and irregular. This is because the teeth of the saw blade are continuously worn during use, resulting in insufficient depth of the teeth, thus making the saw blade not sharp enough and very laborious to use. Therefore, it is necessary to grind and repair the teeth of the saw blade. When the traditional saw blade tooth grinding device is in use, it cannot provide a stable clamping and fixing effect for saw blades of different lengths. Moreover, if there are a large number of saw blades to be ground, the existing equipment can only grind one saw blade at a time during grinding, with low work efficiency and long time consumption, which will further affect subsequent other work processes. For this reason, we design a saw blade tooth grinding device to solve the above technical problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a saw blade tooth grinding device to solve the problems put forward in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A saw blade tooth grinding device includes a workbench with multiple legs at the bottom. The top of the workbench is provided with three mutually parallel placement grooves along the transverse direction. Two mutually parallel electric cylinders are arranged along the transverse direction on the top of the workbench. The electric cylinder sliders of the two electric cylinders are provided with the same U-shaped frame. A hydraulic cylinder is arranged on the inner bottom wall of the U-shaped frame. The output end of the hydraulic cylinder is vertically downward and is connected with a grinding mechanism. A plurality of clamping and fixing components are arranged at equal intervals along the length direction of the inner side wall of the placement groove. The clamping and fixing component includes a clamping plate slidably arranged on the inner bottom wall of the placement groove. The left side surface of the clamping plate is fixedly connected with a sliding rod. A groove for the sliding rod to slide and embed is opened on the inner side wall of the placement groove. An inner groove is opened at one end of the upper side inner wall of the groove far from the groove opening. A wedge block is arranged at one end of the sliding rod far from the clamping plate. A spring is sleeved outside the sliding rod. A threaded sleeve is embedded in the top of the workbench. The threaded sleeve is communicated with the inner groove through a through hole. A threaded rod is threadedly inserted into the threaded sleeve. A knob is arranged at the top end of the threaded rod. The bottom end of the threaded rod extends into the inner part of the inner groove through the through hole and is connected with a contact ball.

[0006] As a preferred scheme of the utility model: A limiting block is arranged on the outer surface of the sliding rod. A limiting groove for the limiting block to slide and embed is opened on one side inner wall of the groove. The limiting groove is open at one end close to the clamping plate.

[0007] As a further preferred solution of the present utility model: the grinding mechanism includes a grinding rod for grinding teeth, and the length direction of the grinding rod is perpendicular to the length direction of the placement groove.

[0019] Please refer to Figures 1 - 4 , in the embodiment of the present utility model, a saw blade tooth grinding device includes a workbench 1 with a plurality of legs at the bottom. Three mutually parallel placement grooves 2 are transversely opened at the top of the workbench 1. The left and right ends of the placement grooves 2 are open. The placement grooves 2 are used to place saw blades. This device can place three saw blades at the same time, that is, grind and process three saw blades at the same time. Two mutually parallel electric cylinders 3 are transversely arranged at the top of the workbench 1. The placement grooves 2 are located between the two electric cylinders 3. The electric cylinder sliders of the two electric cylinders 3 are provided with the same U-shaped frame 4. A hydraulic cylinder is provided on the inner bottom wall of the U-shaped frame 4. The output end of the hydraulic cylinder is vertically downward and connected to a grinding mechanism. The grinding mechanism includes a grinding rod for grinding teeth. The length direction of the grinding rod is perpendicular to the length direction of the placement groove 2. The grinding rod is used to grind and repair the saw blades in the placement groove 2. Moreover, through the three mutually parallel placement grooves 2 provided in this device, up to three saw blades can be ground and repaired at the same time, improving the work efficiency. The grinding mechanism is a prior art, which has been realized and is not the innovation point of this application, so it will not be elaborated in detail and is not specifically shown in the figure. For details, refer to a saw blade grinding and repairing device disclosed in the utility model patent with the authorization announcement number CN 217991154 U.

[0020] A plurality of clamping and fixing components are equidistantly arranged along the length direction of the inner side wall of the placement groove 2. The clamping and fixing components include a clamping plate 6 slidably arranged on the inner bottom wall of the placement groove 2. A sliding rod 18 is fixedly connected to the left side surface of the clamping plate 6. A groove 19 for the sliding rod 18 to slide and embed is opened on the inner side wall of the placement groove 2. An inner groove 14 is opened at one end of the upper side inner wall of the groove 19 far from the groove opening. A wedge block 12 is arranged at one end of the sliding rod 18 far from the clamping plate 6. A spring 7 is sleeved outside the sliding rod 18. The spring 7 is fixedly connected between the outer side surface of the clamping plate 6 and the inner side wall of the placement groove 2. A threaded sleeve 10 is embedded at the top of the workbench 1. The threaded sleeve 10 is located directly above the inner groove 14. The threaded sleeve 10 and the inner groove 14 are communicated through a through hole 11. A threaded rod 9 is internally threaded and inserted into the threaded sleeve 10. A knob 5 is arranged at the top end of the threaded rod 9. The bottom end of the threaded rod 9 extends into the interior of the inner groove 14 through the through hole 11 and is connected with a contact ball 13. The contact ball 13 is in abutting cooperation with the wedge block 12.

[0021] A limiting block 16 is arranged on the outer surface of the sliding rod 18. A limiting groove 17 for the limiting block 16 to slide and embed is opened on one side inner wall of the groove 19. One end of the limiting groove 17 close to the clamping plate 6 is designed to be open; in the structural design of this device, when the contact block 13 is separated from the wedge block 12, the elastic force of the spring 7 is restored, which will drive the clamping plate 6 away from the saw blade, and the sliding rod 18 retracts into the interior of the groove 19. At this time, it is convenient to put in or take out the saw blade. Through the cooperation of the limiting block 16 and the limiting groove 17, the movement of the sliding rod 18 retracting into the interior of the groove 19 can be restricted, that is, the position of the wedge block 12 can be restricted, preventing the contact ball 13 and the wedge block 12 from not being accurately abutted and cooperated when the saw blade is fixed again later, ensuring the feasibility of the cooperation between the device structures and improving the practicability of the device.

[0022] Specifically, when this device clamps and fixes the saw blade, by screwing the knob 5 to drive the threaded rod 9 to rotate, under the action of threaded connection, the threaded rod 9 can drive the contact ball 13 to move downward, and make the contact ball 13 abut against the wedge block 12. Continuing to screw the knob 5, the wedge block 12 can be squeezed through the contact ball 13, and then the sliding rod 18 can be pushed to move in the direction away from the interior of the groove 19, and then the clamping plate 6 can be pushed to move, and the clamping plate 6 can be made to squeeze and fix the saw blade. A plurality of clamping and fixing components are equidistantly arranged along the length direction of the inner side wall of the placement groove 2. Therefore, in the actual use process, the appropriate position and number of clamping and fixing components can be selected according to the length of the saw blade to achieve the best stable clamping and fixing effect. And this device is provided with three placement grooves 2, and up to three saw blades can be polished and repaired at the same time, greatly improving the work efficiency.
