Description

Technical Field

[0001] The utility model belongs to the technical field of grinding mechanisms and relates to an automatic grinding mechanism for mold materials. Background Art

[0002] During the mold material processing process, the mold material will be fine-processed by a grinding mechanism. Grinding is a surface modification technology. It generally refers to a processing method that uses rough objects (sandpaper containing high hardness particles, etc.) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. Grinding is different from polishing. Polishing refers to the use of mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and flat surface. It is a modification of the workpiece surface using polishing tools and abrasive particles or other polishing media.

[0003] When the existing mold material is processed by a grinding mechanism, it is generally necessary to fix it directly under the grinding wheel equipment through a corresponding clamp, and then the corresponding equipment in the mechanism drives the mold material to reciprocate in a certain direction for grinding. However, this method can only process the mold material on one side at a time, and then the mold material is turned over manually, and the mold material is manually removed, turned over and fixed again, which increases the processing and grinding time.

Here, the motor 3 A dial 6 is installed at the rotating shaft, an outer locking arc 61 is installed on the dial 6, a round pin 62 is provided at the edge of the dial 6, a movable groove wheel 63 is installed at one end of the right clamping block 42, radial grooves 64 and inner locking arcs 65 are arranged on the movable groove wheel 63, a tray 7 is provided above the support block 36, an electric telescopic rod 71 is installed at the bottom of the tray 7, a rectangular groove 72 is provided in the tray 7, a connecting seat 8 is installed in the rectangular groove 72, a clamping block 81 is installed in the connecting seat 8, a through groove 82 is provided at the bottom of the clamping block 81, a through hole 9 is provided on the inner wall of the rectangular groove 72, a cylinder 91 is installed in the through hole 9, a spring 92 is installed on the outside of the cylinder 91, and a wedge 93 is installed at the other end of the cylinder 91.

[0028] In this embodiment, the main body 1 is an existing mold material grinding mechanism, which performs grinding work through the grinding wheel above and drives the mold material to reciprocate in a certain direction through the frame below. The specific working method is not described. This case only improves the flipping of the mold material.

[0029] Combination Figure 1 , Figure 2 , Figure 3 As shown, the motor 31 is electrically connected to an external power source, the screw rod 34 is rotatably connected to the inner wall of the cavity 32, both ends of the slide rod 35 are fixedly connected to the inner wall of the cavity 32, and one end of the screw rod 34 passes through the base 3 and is connected to the motor 31. The support rod 41 is rotatably connected to the movable block 4, and the movable block 4 is provided with a thread meshing with the screw rod 34 at the penetration point of the screw rod 34, and a round hole is provided at the bottom of the movable block 4, and the slide rod 35 is inserted into the round hole and slidably connected with the screw rod 34.

[0030] Furthermore, the screw rod 34 here is symmetrically provided with threads running in opposite directions. The screw rod 34 and the slide rod 35 respectively pass through the bottom of the movable block 4. The motor 31 drives the screw rod 34 to rotate, and the movable blocks 4 at both ends move toward each other along the screw rod 34. The slide rod 35 supports and guides the movable block 4.

[0031] Combination Figure 2 , Figure 4 As shown, the sliders 51 are symmetrically installed, and the support plate 5 is slidably connected to the slideway 33 via the sliders 51 .

[0032] Furthermore, the support plate 5 is installed at the bottom of the movable block 4 on the right side. When the movable block 4 moves along the screw rod 34, it will also drag the support plate 5 to move. Then the support plate 5 slides along the slideway 33 through the slider 51 to reduce friction.

[0033] Combination Figure 2 , Figure 5 As shown, the dial 6 and the outer locking arc 61 are installed concentrically, the round pin 62 is eccentrically installed on the dial 6, and the size of the round pin 62 is smaller than the radial groove 64. The dial 6 is located on one side of the movable groove wheel 63, the outer locking arc 61 and the inner locking arc 65 are tangent and slidably connected, and the round pin 62 and the radial groove 64 are slidably connected.

[0034] Furthermore, the dial 6 and the movable groove wheel 63 here together constitute the existing groove wheel structure. When the outer locking arc 61 and the inner locking arc 65 are tangent, the movable groove wheel 63 will not rotate. When the outer locking arc 61 and the inner locking arc 65 are separated, the round pin 62 enters the radial groove 64 and drags the movable groove wheel 63 to rotate a certain angle. In this case, eight radial grooves 64 are arranged in the middle of the movable groove wheel 63. The processed mold material is generally square. The mold material is turned over forty-five degrees each time the movable groove wheel 63 rotates once. Therefore, the mold material can be turned over ninety degrees every time the movable groove wheel 63 rotates twice, and then the mold material is fixed through the tray 7 in cooperation with the electric telescopic rod 71 to prevent the mold material from rotating during grinding.

[0035] Combination Figure 2 , Figure 6 As shown, the tray 7 is mounted on the support block 36 through an electric telescopic rod 71, and the electric telescopic rod 71 is electrically connected to an external power source. The top of the block 81 protrudes from the rectangular groove 72, and the block 81 and the connecting seat 8 are rotatably connected through a pin shaft, and the length of the through groove 82 is greater than the cylinder 91. The cylinder 91 is inserted into the through groove 82, and the size of the wedge block 93 is greater than the through groove 82, and the hypotenuse of the wedge block 93 faces inward. The left end of the spring 92 is fixedly connected to the inner wall of the through hole 9, and the other end of the spring 92 is connected to the cylinder 91, and the diameter of the spring 92 here is greater than the through groove 82.

[0036] Furthermore, the cylinder 91 is inserted into the through groove 82, and the length of the through groove 82 here is much larger than the diameter of the cylinder 91. When the cylinder 91 rotates, the distance between the through groove 82 and the cylinder 91 can satisfy the rotation of the cylinder 91 at a certain angle. The structure such as the block 81 is installed in the middle of the four sides of the rectangular groove 72. The size of the tray 7 here is adapted according to the size of the processing mold material. Using a tray 7 that is not compatible with the mold material may cause the internal block 81 to be unable to effectively fix the mold material.

[0037] The working principle of the utility model is:

[0038] The motor 31 drives the screw rod 34 to rotate, and the movable blocks 4 on both sides move toward each other along the slide rod 35 on the screw rod 34, and the clamping block 42 moves toward the middle mold material until the clamping block 42 stably fixes the middle mold material. The support rod 41 here is rotatably installed on the top of the movable block 42. When fixing the mold material, its position needs to be adjusted so that the fixing point of the clamping block 4 is located in the middle of the mold material.

[0039] When flipping, the motor 31 drives the dial 6 to rotate. When the outer locking arc 61 moves to the inner locking arc 65, the outer locking arc 61 and the inner locking arc 65 are in a tangent and sliding state. At this time, the movable groove wheel 63 will not rotate. When the outer locking arc 61 and the inner locking arc 65 are separated, the round pin 62 moves to the radial groove 64 and drags the movable groove wheel 63 to rotate a certain angle. In this case, eight radial grooves 64 are arranged in the middle of the movable groove wheel 63. The processed mold material is generally square. The mold material is flipped over forty-five degrees each time the movable groove wheel 63 rotates once. Therefore, the movable groove wheel 63 can flip the mold material ninety degrees every time it rotates twice, and then the mold material is fixed through the tray 7 in cooperation with the electric telescopic rod 71 to prevent the mold material from rotating during grinding.

[0040] Every time the mold material is turned over by 90 degrees, the electric telescopic rod 71 lifts the tray 7 upward. When the tray 7 is wrapped around the outside of the mold material and the mold material contacts the wedge block 93, the mold material moves downward along the oblique edge of the wedge block 93. At the same time, the wedge block 93 is squeezed by the mold material, and the cylinder 91 slides outward along the through hole 9. The spring 92 is deformed and compressed. When the wedge block 93 abuts against the block 81, the block 81 will rotate clockwise in the connecting seat 8 based on the pin shaft. The size of the through groove 82 is much larger than the cylinder 91. Therefore, the block 81 will not be interfered with by the cylinder 91 when it rotates within a certain angle range. When the top of the block 81 abuts against the mold material, the electric telescopic rod 71 stops working. Before turning the material, the electric telescopic rod 71 needs to drag the tray 7 downward to separate the wedge block 93 and the mold material. The block 81 will also move to the initial position under the action of the spring 92.

[0041] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the spirit of the present invention.
