Description

Technical Field

[0001] This utility model relates to the field of grinding devices, and more particularly to a grinding device. Background Technology

[0002] High-pressure down-the-hole drill bits employ four main end-face designs: convex, flat, concave, and deeply concave center. Carbide drill bits typically use ball teeth, spring teeth, or a combination of both. During production, the drill bit requires fixed grinding, necessitating a grinding device.

[0003] In existing technologies, such as the Chinese patent announcement CN221984607U entitled "A Grinding Device," a base and a fixing assembly are included. A slide rail is welded to the upper left side of the base, and the fixing assembly is welded to the upper right side of the base. The fixing assembly includes a ring housing, spring rods, a positioning head, a fixing head, and a lead screw. A spring rod is welded inside the ring housing, and a positioning head is welded to the top of the spring rod. A fixing head is located at the front end of the positioning head, and a lead screw is welded to the outer side of the fixing head. Compared to existing grinding devices, this grinding device uses two spring rods to clamp the drill bit through the positioning head, fixing it at the center position. The two fixing assemblies position the drill bit at the center of the ring housing, aligning it with the center of the grinding area. Then, rotating the lead screw fixes the drill bit in four directions, completing the positioning and fixing of the drill bit. When the universal tool holder is grinding the drill bit, the motor drives the inner cover to rotate, causing the universal tool holder to rotate around the drill bit, allowing for all-around machining of the drill bit.

[0004] In existing technologies for workpiece grinding, the turning tool and the grinding component are fixed in the same position, which means that the tool needs to be disassembled and replaced when the workpiece is finished. This leads to the problem that tool disassembly is inconvenient due to the limited installation space, and thus makes the use of the grinding equipment cumbersome.

[0005] Therefore, it is necessary to provide a grinding device to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a grinding device that solves the problem that, since the turning tool and the grinding component are fixed in the same position, the tool needs to be disassembled and replaced when the workpiece is finished turning, which makes tool disassembly inconvenient due to the limited installation space, and thus makes the use of the grinding device cumbersome.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1A schematic diagram of a preferred embodiment of a grinding device provided by this utility model; Figure 2 for Figure 1 The image shows a front view of a grinding apparatus. Figure 3 for Figure 1 The image shows a front view of a support table in a grinding apparatus. Figure 4 for Figure 1 The image shows a front view of a sliding block in a grinding device. The grinding device includes a support platform 1, a sliding groove 2 on the top of the support platform 1, a sliding block 3 movably fitted inside the sliding groove 2, a bearing 4 fixedly connected to the top of the sliding block 3, a first clamping seat 5 movably fitted inside the bearing 4, a control host 6 fixedly mounted on the top of the support platform 1, a second clamping seat 7 movably fitted to the side of the control host 6, an electric slide rail 8 fixedly mounted on the top of the support platform 1, a first sliding seat 9 movably fitted to the top of the electric slide rail 8, a first load-bearing column 10 fixedly connected to the top of the first sliding seat 9, and a cylinder 11 fixedly fitted to the top of the first load-bearing column 10. A grinding disc 12 is fixedly connected to one end of the cylinder 11. A second sliding seat 13 is movably sleeved on the top of the electric slide rail 8. A second load-bearing column 14 is fixedly connected to the top of the second sliding seat 13. A knife rod 15 is fixedly sleeved on the top of the second load-bearing column 14. A bolt 16 is threadedly sleeved on the top of the second load-bearing column 14. A motor 17 is fixedly installed on the top of the side of the sliding block 3. A fixing mechanism 18 is provided on the side of the support platform 1. A sliding ball 19 is movably sleeved on the bottom of the inner cavity of the sliding groove 2. A moving mechanism 20 is provided on the bottom of the support platform 1. A folding plate 21 is fixedly connected to the side of the control host 6.

[0025] There are two grinding discs 12, which are symmetrically distributed about the first clamping seat 5. By setting the grinding discs 12, when the workpiece turning is finished, the cylinder 11 is activated, so that the cylinder 11 drives the grinding discs 12 to be tightly pressed against the workpiece surface. At this time, the first sliding seat 9 is activated and the workpiece is rotated, so that the first sliding seat 9 drives the cylinder 11 to move horizontally through the first load-bearing column 10, that is, drives the grinding discs 12 to move and grind the workpiece, thereby achieving the polishing effect after the workpiece is turned, thus avoiding the problem of frequent tool changes during workpiece grinding, and bringing convenience to the workpiece grinding process.

[0026] Bolt 16 is located directly above the second load-bearing column 14, and the second load-bearing column 14 and the tool bar 15 are perpendicular to each other. By setting bolt 16, when adjusting the position of the tool bar 15, rotating bolt 16 allows bolt 16 to be moved out of the second load-bearing column 14. At this time, pushing the tool bar 15 allows the tool bar 15 to move inside the second load-bearing column 14, thereby achieving the effect of adjusting the position of the tool bar 15.

[0027] The first motor 17 is located in the center of the side of the second clamping seat 7, and the output shaft of the first motor 17 is fixedly sleeved on the side of the first clamping seat 5. By setting the first motor 17, when turning is required, the tool bar 15 is pressed against the surface of the workpiece. At this time, the first motor 17 is started, so that the first motor 17 can drive the workpiece to rotate quickly through the first clamping seat 5, thereby achieving the turning effect of the workpiece.

[0028] The fixing mechanism 18 includes a second motor 181, which is fixedly installed on the side of the support platform 1. A threaded rod 182 is fixedly connected to the output shaft of the second motor 181, and the threaded rod 182 is threadedly sleeved inside the sliding block 3. By setting the fixing mechanism 18, when the workpiece is being turned, the workpiece is sleeved inside the second clamping seat 7. At this time, the second motor 181 is started, so that the second motor 181 drives the sliding block 3 to move horizontally through the threaded rod 182. That is, the sliding block 3 drives the first clamping seat 5 to press tightly against the side of the workpiece, so that the workpiece is pressed and clamped on the side of the workpiece, thus bringing convenience to the clamping and fixing of the workpiece.

[0029] One end of the folding plate 21 is fixedly connected to the other side of the sliding block 3. The folding plate 21 is made of polyethylene. By setting the folding plate 21, when the workpiece is being turned, the folding plate 21 can block the sliding groove 2, thereby avoiding the problem that metal chips generated during the workpiece turning process will fall into the sliding groove 2 and make it difficult for the sliding block 3 to slide, thus improving the cleanliness of the sliding groove 2.

[0030] There are several sliding balls 19, which are evenly distributed at the bottom of the inner cavity of the sliding groove 2. By setting the sliding balls 19, when the sliding block 3 drives the first clamping seat 5 to move horizontally, the sliding balls 19 can support and limit the horizontally moving sliding block 3, thereby avoiding the problem of friction between the sliding block 3 and the bottom of the inner cavity of the sliding groove 2 when it moves horizontally, thus improving the smoothness of the sliding block 3.

[0031] The moving mechanism 20 includes a support column 201, which is fixedly connected to the bottom of the support platform 1. A sliding wheel 202 is installed at the bottom of the support column 201. By setting up the moving mechanism 20, when the grinding device is moving and conveying, the support platform 1 is pushed, so that the sliding wheel 202 can drive the support platform 1 to move horizontally through the support column 201, that is, drive the control host 6 to move horizontally, thereby achieving the effect of moving and conveying the grinding device, and thus bringing convenience to the adjustment of the working position of the grinding device.

[0032] The working principle of the grinding device provided by this utility model is as follows:

[0033] Step 1: First, when the workpiece turning is finished, start cylinder 11, so that cylinder 11 drives the grinding disc 12 to tightly press against the workpiece surface. At this time, start the first sliding seat 9 and rotate the workpiece, so that the first sliding seat 9 drives cylinder 11 to move horizontally through the first supporting column 10, that is, drives the grinding disc 12 to move and grind the workpiece, thereby achieving the polishing effect after workpiece turning, thus avoiding the problem of frequent tool changes during workpiece grinding, thus bringing convenience to the workpiece grinding process. When adjusting the position of tool holder 15, rotate bolt 16, so that bolt 16 can be moved out of the second supporting column 14. At this time, push tool holder 15, so that tool holder 15 can be adjusted to the second supporting column 14. The internal movement of the load-bearing column 14 achieves the adjustment effect of the position of the tool holder 15. When turning is required, the tool holder 15 is pressed against the surface of the workpiece. At this time, the first motor 17 is started, so that the first motor 17 drives the workpiece to rotate rapidly through the first clamping seat 5, thereby achieving the turning effect of the workpiece. When turning the workpiece, the workpiece is sleeved inside the second clamping seat 7. At this time, the second motor 181 is started, so that the second motor 181 drives the sliding block 3 to move horizontally through the threaded rod 182. That is, the sliding block 3 drives the first clamping seat 5 to press tightly against the side of the workpiece, so that the workpiece is pressed and clamped on the side of the workpiece, thereby bringing convenience to the clamping and fixing of the workpiece.

[0034] Step 2: When the workpiece is being turned, the folding plate 21 can shield the sliding groove 2, thus preventing metal chips generated during the workpiece turning process from falling into the sliding groove 2 and making it difficult for the sliding block 3 to slide. This improves the cleanliness of the sliding groove 2. When the sliding block 3 drives the first clamping seat 5 to move horizontally, the sliding ball 19 can support and limit the horizontal movement of the sliding block 3, thus preventing the sliding block 3 from rubbing against the bottom of the inner cavity of the sliding groove 2 during horizontal movement. This improves the smoothness of the sliding block 3. When the grinding device is moved and transported, the support table 1 is pushed, so that the sliding wheel 202 can drive the support table 1 to move horizontally through the support column 201, that is, drive the control host 6 to move horizontally, thus achieving the effect of moving and transporting the grinding device, and thus bringing convenience to the adjustment of the working position of the grinding device.

[0035] Compared with related technologies, the grinding device provided by this utility model has the following beneficial effects:

[0036] By setting the grinding disc 12, when the workpiece turning is finished, the cylinder 11 is activated, so that the cylinder 11 drives the grinding disc 12 to be tightly pressed against the workpiece surface. At this time, the first sliding seat 9 is activated and the workpiece is rotated, so that the first sliding seat 9 drives the cylinder 11 to move horizontally through the first load-bearing column 10, that is, drives the grinding disc 12 to move and grind the workpiece, thereby achieving the polishing effect after the workpiece is turned, thus avoiding the problem of frequent tool changes during workpiece grinding, thus bringing convenience to the workpiece grinding process.
