DETAILED DESCRIPTION

[0023] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] See also Figure 1-Figure 3 The utility model provides a new double-horizontal grinding machine, comprising:

[0027] Base 1, the four corners of the lower surface of the base 1 are supported on the ground by supporting feet;

[0028] A first moving mechanism, which is disposed on the upper surface of the base 1 and has a workbench 16 disposed thereon. The first moving mechanism is configured to drive the workbench 16 to move forward and backward relative to the base 1, i.e., to drive the workbench 16 to move relative to the base 1 along the Y-axis direction;

[0029] Two jigs 6 are provided, symmetrically positioned on either side of the upper surface of the workbench 16. These jigs 6 are used to secure hard and brittle materials. Specifically, the jig 6 is provided with a vacuum adsorption device, and adsorption holes are provided on the upper surface of the jig 6 (not shown). The vacuum adsorption device performs vacuum adsorption on hard and brittle materials, which may be glass or ceramics. In this embodiment, ten pieces of hard and brittle materials can be placed on one jig 6 at a time, allowing for the processing of multiple pieces of hard and brittle materials at once, greatly improving grinding efficiency.

[0030] The door bridge 15 is installed at the rear end of the upper surface of the base 1 and extends along the left and right directions of the base 1;

[0031] A second moving mechanism is provided at the upper end of the gate bridge 15. Two slides 13 are provided on the second moving mechanism. The second moving mechanism is used to drive the two slides 13 to move left and right simultaneously. The slides 13 correspond to the tooling fixtures 6 one by one.

[0032] A horizontal grinding mechanism 3, which is used to grind hard and brittle materials;

[0033] The lifting mechanism is mounted on the slide 13 and corresponds one-to-one with the fixture 6. The lifting mechanism is used to drive the horizontal grinding mechanism 3 to move up and down. Since the number of lifting mechanisms corresponds one-to-one with the fixture 6, the grinding of hard and brittle materials on both sides of the workbench 16 can be independent of each other. Therefore, when the height of the workpiece materials is different, resulting in different starting points for grinding when processing the workpieces on the two fixtures 6, the time spent on readjusting the height can be reduced, and the Z-axis height can be adjusted quickly and efficiently. When the two lifting mechanisms are processing simultaneously, since 20 pieces of hard and brittle materials can be clamped at one time, 20 pieces of hard and brittle materials can be processed simultaneously at one time, greatly improving the processing efficiency compared to traditional equipment.

[0034] Specifically, the first moving mechanism includes two first slide rails 4, which are mounted on the upper surface of the base 1 and slidably engage with a first slider 5 on the lower surface of the workbench 16. The first moving mechanism includes a first motor 18, the output end of which is fixedly connected to a first screw rod 2, which passes through the middle of the lower surface of the workbench 16 and is threadedly connected thereto.

[0035] The second moving mechanism includes a third slide rail 14, and the third slider 17 on the back of the slide 13 slides in cooperation with the third slide rail 14. The second moving mechanism also includes a third motor 11, and the output end of the third motor 11 is fixedly connected to a third screw rod 12, and the third screw rod 12 passes through the middle of the back of the slide 13 and is threadedly connected thereto.

[0036] Specifically, the lifting mechanism includes a second slide rail 7 and a support plate 10. A second slider 8 on the back of the support plate 10 slidably engages with the second slide rail 7. A second motor 9 is also mounted on the slide seat 13. The output end of the second motor 9 is fixedly connected to a second screw rod, which passes through the middle of the back of the support plate 10 and is threadedly connected thereto. The horizontal grinding mechanism 3 is mounted on the front surface of the support plate 10. When the second motor 9 drives the second screw rod to rotate, it drives the support plate 10 up and down, thereby driving the horizontal grinding mechanism 3 up and down. The second screw rod is not shown in the figure.

[0037] Specifically, the horizontal grinding mechanism 3 includes a fourth motor 35, the output end of the fourth motor 35 is fixedly connected to a driving wheel 33, and the driving wheel 33 is connected to a driven wheel 32 through a belt 34. The horizontal grinding mechanism 3 also includes a grinding wheel 31, which is used to grind hard and brittle materials. The grinding wheel 31 is installed on a rotating shaft, and the rotating shaft is rotatably connected to the bottom end of the support plate 10, wherein the bottom end of the support plate 10 is provided with a reinforcing plate protruding outward, so that the support plate 10 is L-shaped, and the driven wheel 32 is installed at the end of the rotating shaft. Since this model adopts a horizontal spindle structure, both ends of the spindle are supported, and the rigidity of the spindle is improved, so that the width of the grinding wheel installed on the spindle is wider. This structure can grind the width of two pieces of hard and brittle materials at one time; since the horizontal spindle solution is adopted, since the front and rear ends of the spindle are supported, the grinding width and the cutting amount can be significantly improved. Compared with the vertical grinder, the grinding efficiency can be effectively improved.
