Description

Technical Field

[0001] The utility model relates to the technical field of metal grinding machines, in particular to a drivable and guided metal grinding machine. Background Art

[0002] The development of metals has greatly facilitated people's daily lives. Metals with different properties can be used to make different items that people need. However, the surface of metals is often not very smooth during processing. In order to make the metal surface smooth and easier to process, a metal grinder has appeared on the market to facilitate people to process and grind the surface of metals.

[0003] However, when the current metal grinder is used, the metal will be ground at the same position on the sandpaper for a period of time, and the same position of the sandpaper will be worn, making it inconvenient to continue grinding the metal. The metal grinder is inconvenient to fix the position of the sandpaper when in use, and the working efficiency is low.

[0004] In summary, how to adjust the grinding position of the metal workpiece on the sandpaper has become an urgent problem that researchers in this field need to solve. Summary of the Invention

[0005] The technical problem to be solved by the utility model is: how to adjust the grinding position of a metal workpiece on sandpaper;

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] The utility model is a drivable guide type metal grinding machine, comprising: a workbench, with support plates provided on both sides thereof; a first connecting plate, which is provided above the workbench and has its ends slidably connected to the corresponding support plates; a second connecting plate, which is driven by a sliding assembly and provided at the bottom of the first connecting plate along the length direction of the first connecting plate; a clamping claw assembly, which is provided at the bottom of the second connecting plate and is suitable for clamping a workpiece; a receiving plate, which is raised and lowered by a lifting assembly and provided on the workbench; and sandpaper, which is provided on the surface of the receiving plate.

[0008] In this solution, the metal workpiece is clamped on the clamping jaw assembly, and the height of the receiving plate is adjusted by the lifting assembly so that the sandpaper contacts the workpiece. The sliding assembly drives the second connecting plate and the workpiece to reciprocate relative to the length direction of the first connecting plate, and the workpiece and the sandpaper are ground back and forth. When the ground sandpaper is worn, the position of the first connecting plate is adjusted relative to the support plate, and the workpiece is brought into contact with the sandpaper at another position to continue grinding.

[0009] In order to illustrate how the first connecting plate moves relative to the supporting plate, the present invention adopts the supporting plate having a slide groove along its width direction; the end of the first connecting plate is located in the slide groove; a plurality of positioning holes are provided on the first connecting plate and are located above or below the slide groove; a fixing seat is provided near the end teeth of the first connecting plate; a clamping rod passes through the fixing seat, and its end is suitable for inserting into one of the positioning holes; a limit spring, one end of which is against the fixing seat, and the other end is against the limit piece on the clamping rod;

[0010] Both ends of the first connecting plate are provided with a clamping rod. When the clamping rod is disengaged from the positioning hole, the limit spring contracts. When the clamping rod is matched with the positioning hole, the limit spring resets and the clamping rod is clamped into the corresponding positioning hole. Since the positioning holes are arranged in a line, the pull rod selects the corresponding positioning hole to match, so as to realize the positioning of the first connecting plate after moving relative to the support plate.

[0016] In this solution, by turning the knob, the rotating rod rotates, and the rotating rod transmits the torque to the adjusting rod, thereby adjusting the screw sleeve to rise or fall, and realizing the rise or fall of the receiving plate. The telescopic part plays a guiding role to ensure that the receiving plate is in a horizontal state.

[0017] How to install the sandpaper?

When working, the card plate is pulled upward by manpower, and the card plate compresses the fixing spring while sliding longitudinally on the fixing rod. After the sandpaper is spread flat between the card plate and the receiving plate, the card plate is released, and the card plate returns to its original position through the elasticity of the fixing spring, and tightly presses against the sandpaper to fix its position, which is convenient for fixing the position of the sandpaper, convenient for people to operate and use, and improves the working efficiency of the device.

[0033] Working principle: This metal grinder is first convenient for changing the grinding position of the metal. The metal to be ground is placed in the four-jaw chuck 10, and the fixed nut 12 is rotated manually. The fixed nut 12 moves laterally on the limit rod 11 through the thread set on the inner side until the four-jaw chuck 10 tightly clamps the metal to fix its position. Then, the fixed nut 12 is stopped and the motor is started. The motor uses AC power to drive the adjusting screw 6 to realize forward and reverse rotation. The adjusting screw 6 rotates forward and backward on the first connecting plate 3 through the fixing plate 8. When the adjusting screw 6 rotates forward and backward, the slider 7 and the second connecting plate 9 are driven to reciprocate laterally on the first connecting plate 3 through the thread set on the outer side, which is convenient for driving The metal fixed under the second connecting plate 9 is ground back and forth on the sandpaper 21. When the metal is ground at the same position of the sandpaper 21 for a long time and needs to be changed, the clamping rod 4 is pulled outward by manpower. The clamping rod 4 moves outward on the first connecting plate 3 while compressing the limit spring 5 until the clamping rod 4 is removed from the positioning hole opened on the outside of the support plate 2, so that the first connecting plate 3 can slide horizontally on the support plate 2.

The card plate 20 returns to its original position through the elasticity of the fixing spring 19 and tightly presses against the sandpaper 21 to fix its position, which is convenient for metal grinding. When the metal is ground for a long time, the volume will be reduced. The side of the metal that needs to be ground cannot fit closely with the sandpaper 21, which will affect the grinding effect of the metal. When the use height of the sandpaper 21 needs to be adjusted, the manual rotation is performed. Move the knob 13, and the knob 13 rotates in situ on the workbench 1.
