Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a drill bit cutting edge grinding machine. Background Technology

[0002] Slotted drill bits are made of cemented carbide, such as YG11C, YK05, and YK20, which have high hardness, high wear resistance, and good impact resistance. They are the key part of drill bits used for cutting rocks or other materials. Compared with other complex-shaped drill bits, slotted drill bits are relatively easy to design and manufacture, and have lower costs, making them more affordable and cost-effective in the market. Due to their relatively simple structure, they are less prone to failure and can work stably under normal use conditions. They are highly adaptable to rock properties and can be used for drilling in rocks of different hardness and properties. After the drill bit wears out, it needs to be ground with a grinder. However, most existing grinders have difficulty clamping drill bits of different diameters and cannot grind both sides of the drill bit's cutting edge at the same time, increasing grinding time. Therefore, we have introduced a drill bit cutting edge grinding machine. Utility Model Content

[0003] The main objective of this invention is to provide a drill bit edge grinding machine that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A drill bit edge grinding machine includes a base, a grinding device is fixedly connected to the upper right side of the base, a lifting device and a clamping device are fixedly connected to the upper left side of the base, and a drill bit body is interposed between the clamping device and the lifting device.

[0006] Preferably, the pressing device includes a horizontal plate, with guide rods fixedly connected to the front and rear lower ends of the horizontal plate, a threaded rod threadedly connected to the middle upper end of the horizontal plate, a turntable fixedly connected to the upper end of the threaded rod, and an upper pressing block movably connected to the lower end of the threaded rod via a bearing. The upper pressing block is movably connected to the two guide rods through an interlocking connection.

[0007] Preferably, both guide rods are fixedly connected to the upper end of the base, and the upper pressure block has a "V" shaped structure.

[0008] Preferably, the lifting device includes a base block, with a second top rod fixedly connected to the left front end and the left rear end of the base block, and a first top rod fixedly connected to the right front end and the right rear end of the base block. The two first top rods are connected to a pressing block, and the two second top rods are connected to a pressing block.

[0009] Preferably, both of the pressing blocks are "V" shaped structures, and the bottom block is fixedly connected to the base.

[0010] Preferably, the upper pressure block is located between the two lower pressure blocks.

[0011] Preferably, the grinding device includes a rodless cylinder, a sliding end is provided on the rodless cylinder, a connecting seat is fixedly connected to the sliding end, a motor is fixedly connected to the connecting seat, a rotating rod is fixedly connected to the output end of the motor, and a grinding disc is fixedly connected to the outer surface of the rotating rod.

[0012] Preferably, the rodless cylinder is fixedly connected to the upper end of the base.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by setting up a lifting device and a pressing device, the drill bit body is placed between two lower pressing blocks. Both lower pressing blocks are "V" shaped structures. The drill bit body will naturally move closer to the bending part of the lower pressing block. At this time, the turntable is rotated, causing the turntable to drive the threaded rod to rotate. The upper pressing block, which is movably connected to the lower end of the threaded rod, will press down at the same time. The upper pressing block is located between the two lower pressing blocks. As the upper pressing block presses down, the upper pressing block, together with the two lower pressing blocks, presses the drill bit body tightly, preventing the drill bit body from shaking during grinding.

[0015] 2. In this utility model, by setting up a grinding device, after the drill bit body is fixed, the rodless cylinder is started to work. The sliding end on the rodless cylinder drives the motor to move closer to the drill bit body. The motor drives the rotating rod and the grinding disc to rotate. The grinding disc has a structure that is narrow in the middle and wide at both ends, which can grind both sides of the drill bit body at the same time, thus improving the grinding efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A drill bit edge grinding machine includes a base 1, a grinding device 5 fixedly connected to the upper right side of the base 1, a lifting device 4 and a clamping device 3 fixedly connected to the upper left side of the base 1, and a drill bit body 2 interspersed between the clamping device 3 and the lifting device 4.

[0026] In this embodiment, the pressing device 3 includes a horizontal plate 31. Guide rods 35 are fixedly connected to the front and rear of the lower end of the horizontal plate 31. A threaded rod 33 is threadedly connected to the middle of the upper end of the horizontal plate 31. A turntable 32 is fixedly connected to the upper end of the threaded rod 33. An upper pressure block 34 is movably connected to the lower end of the threaded rod 33 through a bearing. The upper pressure block 34 is movably connected to the two guide rods 35.

[0027] Both guide rods 35 are fixedly connected to the upper end of the base 1, and the upper pressure block 34 has a "V" shaped structure.

[0028] The lifting device 4 includes a base block 41. The left front end and the left rear end of the base block 41 are fixedly connected to a second top rod 44. The right front end and the right rear end of the base block 41 are fixedly connected to a first top rod 42. The two first top rods 42 are connected to a lower pressure block 43. The two second top rods 44 are connected to the lower pressure block 43. The two lower pressure blocks 43 are both "V" shaped structures. The base block 41 is fixedly connected to the base 1. The upper pressure block 34 is located between the two lower pressure blocks 43.

[0029] With the above scheme: when the turntable 32 rotates, it will drive the threaded rod 33 to rotate together. The lower end of the threaded rod 33 is movably connected to the upper pressure block 34, and the upper pressure block 34 is exactly located above the two lower pressure blocks 43. As the threaded rod 33 rotates, under the action of the threaded transmission, the upper pressure block 34 will move smoothly downward along the axis of the threaded rod 33. When the upper pressure block 34 gradually presses down, it forms a tightly fitted clamping system with the two lower pressure blocks 43. The upper pressure block 34 applies downward pressure from above, while the two lower pressure blocks 43 provide stable support from both sides. The three work together to firmly press the drill bit body 2.

[0030] In this embodiment, the grinding device 5 includes a rodless cylinder 51, a sliding end 56 is provided on the rodless cylinder 51, a connecting seat 52 is fixedly connected to the sliding end 56, a motor 53 is fixedly connected to the connecting seat 52, a rotating rod 55 is fixedly connected to the output end of the motor 53, and a grinding disc 54 is fixedly connected to the outer surface of the rotating rod 55; the rodless cylinder 51 is fixedly connected to the upper end of the base 1.

[0031] It should be noted that this utility model describes a drill bit edge grinding machine. Before grinding the drill bit body 2, it must be precisely placed between two pressure blocks 43. Both pressure blocks 43 are "V" shaped, and this unique shape has excellent guiding and positioning functions. When the drill bit body 2 is placed there, due to gravity and the natural guidance of the "V" shaped structure, the drill bit body 2 will naturally move towards the bend of the pressure block 43, thus initially achieving a relatively stable placement state, laying a good foundation for the subsequent clamping operation. Next, the operator needs to slowly and steadily rotate the turntable 32, and the turntable 32 and the threaded rod 33... The drill bit body 2 is connected by a specific transmission mechanism. When the turntable 32 rotates, it drives the threaded rod 33 to rotate as well. The lower end of the threaded rod 33 is movably connected to the upper pressure block 34, which is positioned directly above the two lower pressure blocks 43. As the threaded rod 33 rotates, the upper pressure block 34 moves smoothly downward along the axis of the threaded rod 33 under the action of the threaded transmission. As the upper pressure block 34 gradually presses down, it forms a tightly fitted clamping system with the two lower pressure blocks 43. The upper pressure block 34 applies downward pressure from above, while the two lower pressure blocks 43 provide stable support from both sides. The three work together to firmly hold the drill bit body 2 in place. The ground clamping method effectively prevents the drill bit body 2 from shaking or shifting during subsequent grinding, thus ensuring the accuracy and quality of the grinding operation. After the drill bit body 2 is fixed, the rodless cylinder 51 can be started. As a common pneumatic actuator, the rodless cylinder 51 has the advantages of compact structure and smooth movement. When the rodless cylinder 51 is started, its sliding end 56 will move linearly along the axis of the cylinder under the action of the air pressure inside the cylinder. The sliding end 56 is fixedly connected to the motor 53, so it will drive the motor 53 to move closer to the drill bit body 2. The motor 53 serves as the power source. The device will start up quickly after being powered on, causing the rotating rod 55 to rotate at high speed. The other end of the rotating rod 55 is connected to the grinding disc 54. As the rotating rod 55 rotates, the grinding disc 54 will also rotate at high speed. It is worth mentioning that the grinding disc 54 is designed with a special structure that is narrow in the middle and wide at both ends. This structure allows the wider parts at both ends of the grinding disc 54 to contact both sides of the drill bit body 2 simultaneously during rotation, thereby achieving synchronous grinding of both sides of the drill bit body 2. Compared with the traditional single-sided grinding method, this double-sided simultaneous grinding method greatly improves grinding efficiency, shortens processing time, and also ensures the consistency and uniformity of grinding both sides of the drill bit body 2.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
