Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment, and in particular to an automated sheet metal grinding equipment. Background Technology

[0002] Sheet metal parts are widely used in modern manufacturing, covering many fields such as automobiles, electronics, and machinery. After sheet metal parts are processed and formed, their surfaces often have problems such as burrs and scratches. These defects not only affect the appearance quality of the sheet metal parts, but may also reduce their performance and service life. Therefore, grinding has become an indispensable and important step in the sheet metal processing.

[0003] A search revealed Chinese Patent Publication No. CN220516363U, which discloses an automated grinding device. The device includes a processing table with an L-shaped plate fixed to its top. Two rectangular cylinders are fixed to the processing table, and a first hollow plate is fixed and connected to the sides of the two cylinders that are close to each other. When the extrusion plate moves downwards, the wider portion of the extrusion plate presses against the pressure plate, causing the pressure plate and clamping assembly to move. This allows the clamping assembly to clamp the workpiece. As the extrusion plate continues to move downwards, the position of the pressure plate is restricted by the wider portion of the extrusion plate, meaning the pressure plate will not move further, and the clamping assembly always holds the workpiece. Further downward movement of the extrusion plate causes the connecting plate to move downwards, allowing the grinding disc to grind the workpiece. After grinding, the extrusion plate moves upwards, and the rebound force of the second elastic element causes the clamping assembly to release the workpiece. This allows the workpiece to be automatically clamped and released without manual operation.

[0004] Although the device has some improvements, it still has the following shortcomings. In this device, the pressure plate is pressed by the extrusion plate, which drives the cylindrical rod to move and press the second elastic element to maintain the initial tension. Then, the pull rod is operated to change the position of the clamping plate to achieve clamping and fixation. However, since the pressure plate is in a movable state and is only stabilized by the second elastic element, the device does not clamp rigidly. If there is an external force during the grinding process, the device will shift, which will affect the grinding accuracy.

[0005] Furthermore, the positions of the clamps on both sides of the device need to be adjusted separately, making it rather cumbersome to operate.

[0006] Therefore, an automated sheet metal grinding equipment is proposed to solve the above problems. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides an automated sheet metal grinding equipment, which aims to solve the problem that the clamping is not rigid and is easily deflected by external forces, thus affecting the grinding accuracy.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an automated sheet metal grinding equipment, comprising a machine base, a support plate fixedly connected to the upper surface of the machine base, an automatic grinding component disposed on the right surface of the support plate, a fixing mechanism disposed on the rear surface of the machine base, the fixing mechanism comprising a driving component and a clamping component, the automatic grinding component comprising a guide plate, a second roller rotatably connected to the inner wall of the guide plate, a first roller rotatably connected to the inner wall of the support plate, a guide block slidably connected to the outer wall of the guide plate, an electric push rod disposed on the upper surface of the guide block, and a grinding machine disposed at the bottom end of the output shaft of the electric push rod.

The middle section of the lower surface of the guide block is convex, and the lower surface of the guide block is in contact with the upper surface of roller two.

[0017] As a further description of the above technical solution:

[0018] The fixing plate is fixedly connected to the right surface of the support plate, the slide groove is inclined, and the slide rod slides on the inner wall of the inclined groove.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, through the cooperation of the fixing mechanism, the starting motor can drive the screw to move the positioning plate. By using the cooperation of the inclined groove, the sliding groove and the sliding rod, the clamping plates on both sides can be moved closer or opened synchronously to rigidly fix the sheet metal parts and ensure stable clamping.

The rest of the operations are completed automatically, saving labor costs and realizing semi-automatic grinding. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] Reference Figure 1 , Figure 3 An embodiment of this utility model provides an automated sheet metal grinding device, including a machine base 1 for supporting the overall device. Support legs are installed on the lower surface of the machine base 1, and a support plate 2 is fixedly connected to the upper surface of the machine base 1. An automatic grinding component is provided on the right surface of the support plate 2. The automatic grinding component can grind sheet metal parts of different heights and sizes. A fixing mechanism is provided on the rear surface of the machine base 1. The fixing mechanism can automatically clamp and fix the workpiece, and it is a rigid fixation, which can ensure the stability of the clamping. The fixing mechanism includes a drive component and a clamping component.

[0035] Reference Figure 1 , Figure 2 , Figure 4 The automatic grinding assembly includes a guide plate 31, with multiple sets of rollers 33 rotatably connected to the inner wall of the guide plate 31, evenly distributed laterally, and capable of rotation. Multiple sets of rollers 33 are rotatably connected to the inner wall of the support plate 2, evenly distributed front-to-back, and capable of rotation. A guide block 34 is slidably connected to the outer wall of the guide plate 31, and capable of lateral sliding. An electric push rod 35 is mounted on the upper surface of the guide block 34, and a grinding machine 36 is mounted at the bottom end of the output shaft of the electric push rod 35. Both the electric push rod 35 and the grinding machine 36 are existing technologies and can be implemented by those skilled in the art. Since they are existing technologies, they will not be described in detail in this case. The electric push rod 35 can control the height of the grinding machine 36, and the lower surface of the grinding machine 36 is equipped with a grinding disc, which can uniformly grind the surface of the workpiece after startup.

[0036] Reference Figure 1 , Figure 2 , Figure 4The support plate 2 is provided in two sets, which are symmetrically distributed about the center line of the machine base 1. The two sets of support plates 2 are located at the left and right ends of the upper surface of the machine base 1, respectively. The lower surfaces of the left and right ends of the guide plate 31 are convex. The two sets of support plates 2 can provide stable support for the guide plate 31. The lower surface of the guide plate 31 is in contact with the upper surface of the roller 1 32, and the roller 1 32 provides support for the guide plate 31. This causes the roller 1 32 to rotate when the guide plate 31 slides back and forth, reducing the friction during sliding and making it easier to adjust the position. The middle section of the lower surface of the guide block 34 is convex. The lower surface of the guide block 34 is in contact with the upper surface of the roller 2 33, and the roller 2 33 provides support for the guide block 34. This causes the roller 2 33 to rotate when the guide block 34 slides left and right, reducing the friction during sliding and making it easier to adjust the position. The top of the electric push rod 35 is a square protrusion that can be gripped by hand, driving the device to move flexibly back and forth and left and right to achieve grinding of different positions of the sheet metal parts.

[0037] Reference Figure 1 , Figure 3 The clamping assembly includes a fixed plate 51, a slider 53 slidably connected to the rear surface of the fixed plate 51, the slider 53 moves longitudinally, a positioning plate 52 is fixedly connected to the rear surface of the slider 53, a sliding groove 501 is formed on the rear surface of the fixed plate 51, an inclined groove 502 is formed on the rear surface of the positioning plate 52, a sliding rod 55 is slidably connected to the inner wall of the sliding groove 501, a protrusion is provided in the middle section of the upper surface of the sliding rod 55, which fits with the sliding groove 501, so that the sliding rod 55 can only move left and right, and a clamping plate 54 is fixedly connected to the front surface of the sliding rod 55. There are two sets of sliding groove 501, inclined groove 502, sliding rod 55 and clamping plate 54, which are symmetrically distributed on the left and right sides with respect to the center line of the fixed plate 51.

[0038] Reference Figure 1 , Figure 3 The fixing plate 51 is fixedly connected to the right surface of the support plate 2. The left and right sides of the fixing plate 51 are fixed to the two support plates 2. The slide groove 501 is opened in an inclined shape. The slide rod 55 slides on the inner wall of the inclined groove 502. The outer wall of the slide rod 55 is in contact with the inner wall of the inclined groove 502. When the slide groove 501 moves longitudinally, it will squeeze the slide rod 55, so that the slide rods 55 on both sides and the clamping plate 54 move closer or open synchronously. The clamping plate 54 slides on the upper surface of the machine base 1 and slides laterally. The lower surface of the clamping plate 54 is in contact with the upper surface of the machine base 1.

[0039] Reference Figure 1 , Figure 3The drive assembly includes a motor 41, and a screw 42 is fixedly connected to the output shaft of the motor 41. Both the motor 41 and the screw 42 are existing technologies and can be implemented by those skilled in the art. Since they are existing technologies, they will not be described in detail in this case. After the motor 41 is started, it can drive the screw 42 to rotate. A connecting block 43 is fixedly connected to the rear surface of the positioning plate 52. The motor 41 is set on the rear surface of the machine base 1. The screw 42 passes through and is threadedly connected to the upper surface of the connecting block 43. When the screw 42 rotates, it will drive the connecting block 43 to move longitudinally.

[0040] Working principle: First, place the sheet metal part to be ground in the center of the machine base 1. Then, start the motor 41 to drive the screw 42 to rotate. The rotating screw 42 drives the connecting block 43 and the positioning plate 52 to move upward. During the upward movement of the positioning plate 52, the inclined groove 502 on it will squeeze the slide rod 55, so that the slide rods 55 on both sides and the clamping plate 54 move closer together to clamp the sheet metal part. When the sheet metal part is tightly clamped, turn off the motor 41 to achieve rigid fixation of the sheet metal part and ensure the stability of the workpiece during the grinding process.

[0041] During grinding, the electric push rod 35 is activated to bring the grinding machine 36 to a suitable height, and then the grinding machine 36 is started to grind. The square protrusion at the top of the electric push rod 35 can be manually grasped. Since the guide block 34 can slide flexibly laterally on the outer wall of the guide plate 31, and the guide plate 31 can slide flexibly back and forth on the inner wall of the support plate 2, the position of the grinding machine 36 can be flexibly adjusted back, forth, left, and right, so as to achieve grinding of different positions on the surface of sheet metal parts of different heights and sizes.

[0042] After grinding, turn off the electric push rod 35 and the grinder 36, and start the motor 41 to drive the screw 42 to reverse, which in turn drives the connecting block 43 and the positioning plate 52 to move downward, thereby achieving reverse compression of the slide rod 55. This causes the slide rods 55 on both sides and the clamping plate 54 to open simultaneously, releasing the clamping of the sheet metal part. Finally, the sheet metal part can be removed.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
