Description

Technical Field

[0001] This invention relates to the field of drill bit production, and more specifically to a complete set of surface treatment equipment and method for drill bit production. Background Technology

[0002] A drill bit is a cutting tool with a cutting edge at the end. It is widely used in woodworking, industry, geology and other fields. As a precision tool, the manufacturing process of a drill bit includes the steps of material selection, cutting, shaping, grinding, grooving, drill tip treatment, surface treatment and inspection. Among them, the surface treatment operation is to remove the defects on the surface of the drill bit through operations such as grinding, pickling and polishing, so as to make the surface of the drill bit smoother and thus improve the overall precision of the drill bit.

[0003] Existing grinding operations are generally divided into manual grinding and machine grinding. Manual grinding, as the name suggests, involves workers using handheld grinding wheels and other grinding tools to grind the barbs and other protrusions on the surface of the drill bit, and to shape and smooth the surface of the drill bit. Machine grinding generally uses sandblasting. Although this grinding method is efficient and can make the surface of the drill bit smooth, it cannot remove some protrusions. Therefore, after machine grinding, manual inspection is often still required.

[0004] Even after grinding, drill bits often still contain rust or impurities in small grooves such as chip flutes, which cannot be removed by ordinary grinding operations.

[0005] To address the above issues, a new type of grinding device is needed to overcome the shortcomings of existing machine grinding and manual grinding, and to perform surface treatment on drill bits through a combination of acid washing and grinding, thus solving problems that cannot be solved by grinding operations alone. Summary of the Invention

[0006] The present invention addresses the technical problems mentioned in the background section and proposes the following technical solutions: A complete set of surface treatment equipment for drill bit production includes a base, a drill bit placement table, a grinding device, and an acid pickling device. The base is a hollow structure with a placement table mounting slot. The left and right sides of the drill bit placement table are rotatably connected to the inner walls of the placement table mounting slot. The drill bit placement table has several drill bit placement slots arranged in an array. A drill tip plate and a drill shank clamp are respectively provided on the left and right sides of the drill bit placement slot. A motor slot is provided on one side of the drill shank clamp, and a first motor is provided in the motor slot. The first motor is connected to the drill shank clamp. A second motor is provided inside the base, and the second motor is connected to a gear set. The gear set meshes with one end of the drill bit placement table, and the rotation of the drill bit placement table can be controlled by rotating the gear set. The grinding device includes a fixed cover, a grinding motor, a grinding roller, and a linear module. The fixed cover is installed above the device base and hinged to the device base. The linear module is installed below the fixed cover. A moving module on the linear module is connected to a motor mounting plate. The grinding motor is fixed on the motor mounting plate. Two grinding roller bases are provided on the motor mounting plate. Both ends of the grinding roller are rotatably connected to the two grinding roller bases respectively. One end of the grinding roller is connected to the grinding motor. The pickling device is a pickling tank structure, and the pickling device is located inside the device base and directly below the drill bit placement platform.

[0007] Preferably, a sealing shell is provided on the outer periphery of the first motor, and the sealing shell encloses the first motor in the motor slot.

[0008] Preferably, the gear set is a reduction gear set, and rotating rods are symmetrically arranged on the left and right sides of the drill bit placement platform. A rotating seat is provided on the inner wall of the mounting groove of the placement platform. The rotating rods on the left and right sides are rotatably connected to the two rotating seats respectively, and the rotating front end of one side passes through the rotating seat and meshes with the gear set.

[0009] Preferably, the fixed cover is provided with multiple sets of linear modules installed side by side, each linear module is equipped with a motor mounting plate, and each motor mounting plate is provided with a grinding motor and a grinding roller.

[0010] A surface treatment method for drill bit production, comprising using the complete set of equipment as described in the preceding claims, wherein the specific method is as follows: S1. After the drill bit production is completed, place the drill bits in sequence on the drill bit placement table, and place the drill tip on the drill tip plate. Insert the drill shank into the drill shank clamp until the drill bit placement slot on the drill bit placement table is full. S2. Pull the fixed cover of the grinding device to make the grinding roller contact the drill bit surface. Then, start the grinding motor and start the linear module and the first motor at the same time. This allows the grinding roller to move left and right while grinding, and the drill bit will also rotate with the first motor. This makes it convenient for the grinding roller to grind different parts of the drill bit surface and remove burrs and other imperfections from the drill bit surface.

[0011] S3. After grinding is finished, lift the fixed cover of the grinding device to raise the grinding device and move the grinding roller away from the drill bit. Then start the second motor and rotate the drill bit placement table until it is rotated 180°. At this time, the drill bit fixed on the drill bit placement table will face down and be submerged in the pickling device.

[0012] S4. Start the first motor to drive the drill bit to rotate, thereby performing acid washing on the drill bit and removing impurities from its surface.

[0013] S5. Finally, the drill bit is flipped to the top again by the first motor, and then removed from the drill bit placement table to complete the initial surface treatment.

[0014] The beneficial effects of this invention are: 1. By setting up a drill bit placement platform and a grinding device on the platform, a combination of grinding rollers, motors, and linear modules is used to replace manual grinding and existing abrasive grinding. This method is more efficient than manual grinding and achieves higher precision and accuracy than abrasive grinding. Furthermore, by setting up an acid pickling device on the base of the device, the drill bit after grinding can be immersed in acid pickling solution by rotating the drill bit placement platform with a motor. This removes the chip grooves or adhering substances from the surface of the drill bit, resulting in a smoother surface and a sharper cutting edge after grinding.

[0015] 2. In order to protect the drill bit from damage caused by the motor being immersed in the pickling solution during the pickling process, this application sets up a sealed shell structure to enclose the first motor in the motor slot, which can effectively prevent the motor from contacting the pickling solution, thereby improving the service life of the motor and reducing the cost of use.

[0016] 3. A gear set is installed between the drill bit placement platform and the second motor, and the gear set is a reduction gear set. Without affecting the rotation of the drill bit placement platform driven by the second motor, the rotation angle of the drill bit placement platform is adjusted by the reduction gear set, so that the adjustment angle is more precise. This can prevent the drill bit placement platform from deviating due to the rotation angle of the second motor, so that the grinding angle does not reach the set area during grinding operations, resulting in reduced grinding accuracy.

[0017] 4. By setting up multiple grinding equipment, grinding efficiency can be improved without reducing grinding quality. Attached Figure Description

The base 1 is a hollow structure. A placement table mounting groove 1-1 is provided on the base 1. The left and right sides of the drill bit placement table 2 are rotatably connected to the inner walls of the placement table mounting groove 1-1, respectively. Several drill bit placement grooves 2-1 are arranged in an array on the drill bit placement table 2. A drill tip plate 2-2 and a drill shank clamp 2-3 are provided on the left and right sides of the drill bit placement groove 2-1, respectively. A motor slot 2-4 is provided on one side of the drill shank clamp 2-3. A first motor 2-5 is provided in the motor slot 2-4 and is connected to the drill shank clamp 2-3. A second motor 5 is provided inside the base 1. The second motor 5 is connected to a gear set 6. The gear set 6 meshes with one end of the drill bit placement table 2 and can control the rotation of the drill bit placement table 2 by rotating the gear set 6. The grinding device 3 includes a fixed cover 3-1, a grinding motor 3-2, a grinding roller 3-3, and a linear module 3-4. The fixed cover 3-1 is installed above the device base 1 and hinged to the device base 1. The linear module 3-4 is installed below the fixed cover 3-1. The movable module on the linear module 3-4 is connected to the motor mounting plate 3-5. The grinding motor 3-2 is fixed on the motor mounting plate 3-5. Two grinding roller bases 3-6 are provided on the motor mounting plate 3-5. Both ends of the grinding roller 3-3 are rotatably connected to the two grinding roller bases 3-5 respectively. One end of the grinding roller 3-3 is connected to the grinding motor 3-2. The pickling device 4 is a pickling tank structure. The pickling device 4 is located inside the device base 1 and directly below the drill bit placement platform 2.

[0023] In actual operation, S1: After the drill bit production is completed, the drill bits are placed in sequence on the drill bit placement table 2, and the drill tip is placed on the drill tip top plate 2-2. The drill shank is inserted into the drill shank clamp 2-3 until the drill bit placement slot 2-1 on the drill bit placement table 2 is full. S2. Pull the fixed cover 3-1 of the grinding device 3 so that the grinding roller 3-3 contacts the surface of the drill bit. Then, start the grinding motor 3-2 and start the linear module 3-4 and the first motor 2-5 at the same time. This allows the grinding roller 3-3 to move left and right while grinding, and the drill bit will also rotate with the first motor 2-5. This makes it convenient for the grinding roller 3-3 to perform grinding operations on different positions on the surface of the drill bit and remove burrs and other debris from the surface of the drill bit.

[0024] S3. After grinding is finished, lift the fixed cover 3-1 of the grinding device 3 to raise the grinding device 3 and move the grinding roller 3-3 away from the drill bit. Then start the second motor 5 and rotate the drill bit placement table 2 through the second motor 5 until it is rotated 180°.

The sealing shell 7 encloses the first motor 2-5 in the motor slot 2-4. By enclosing the first motor 2-5 in the motor slot 2-4, the problem of the motor being immersed in the pickling solution during the pickling of the drill bit, which would cause damage to the motor, can be avoided.

[0028] Example 3 Reference Figure 2 The difference between this embodiment and embodiment one is that the gear set 6 is a reduction gear set.
