Description

A stainless steel lock-type weight processing and polishing device Technical Field

[0001] This utility model relates to the field of weight processing technology, specifically a stainless steel lock-type weight processing and polishing device. Background Technology

[0002] Lock-type weights are specially designed standard weight blocks, mainly used to calibrate weighing equipment such as balances and electronic scales to ensure measurement accuracy. Their name comes from their resemblance to a "lock," with a groove or handle on the top for clamping or fixing, avoiding direct contact with the surface and affecting accuracy. During the production of lock-type weights, polishing makes the weights look more aesthetically pleasing, and polishing also facilitates quality control.

[0003] A search revealed a Chinese patent for a polishing device for weight processing, publication number CN217619831U. The device includes a machine base with an arc-shaped plate for supporting the weight. A lifting assembly is provided on the machine base below the arc-shaped plate to move the arc-shaped plate up and down. A first clamping assembly is provided on the left side of the arc-shaped plate to clamp the weight and to rotate the weight.

[0004] The above-mentioned device allows the operator to place the weight on the arc plate first, and then start the equipment to clamp the weight through the first clamping component and the second clamping component. At this time, the lifting component can drive the arc plate to move downward, and then the polishing device polishes the weight. At the same time, the first clamping component, with the cooperation of the second clamping component, can drive the weight to rotate for polishing.

[0005] However, it uses multiple components to push the clamping plate for clamping, resulting in a relatively simple structure. It can only be used for polishing cylindrical weights. When polishing lock-type valves, it is difficult to fix them in place, and the polishing roller is fixed in place, making it difficult to change the polishing material according to the steps, resulting in poor flexibility in use. Summary of the Invention

[0006] The purpose of this invention is to provide a stainless steel lock-type weight processing and polishing device, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A stainless steel lock-type weight processing and polishing device includes a worktable, a turntable rotatably mounted at the center of the top of the worktable, a support frame fixedly connected to the rear of the top of the worktable, and a polishing component provided at the top of the support frame.

[0009] A magnetic chuck is mounted on the top of the turntable, and a lock-type weight body is set on the top of the magnetic chuck. The polishing assembly has two sliders. A groove matching the sliders is set at the center of the upper and lower ends of the support frame. The two sliders are slidably installed in the groove at the support frame. An electric telescopic rod is fixedly installed on the top of the slider. The push rod end of the electric telescopic rod is connected to a mounting frame. Polishing wheel one and polishing wheel two are respectively rotatably installed inside the two mounting frames through rotating rods. A polishing motor is installed on one side of the mounting frame. A driven wheel is connected to the end of the rotating rod near the polishing motor. A driving wheel is installed at the end of the drive shaft of the polishing motor. A transmission toothed belt is set on the outer ring of the driving wheel and the driven wheel.

[0010] Preferably, the center points of the magnetic chuck, polishing wheel one, and polishing wheel two are on the same straight line, polishing wheel one is made of brown corundum material, and polishing wheel two is made of leather material.

[0011] Preferably, an electric telescopic rod 2 is installed at the center of both the front and rear ends of the support frame, and the drive shafts of the two electric telescopic rod 2 are respectively connected to two sliders.

[0012] Preferably, a cleaning air pipe is provided on one side of the top of the workbench. The cleaning air pipe is flexible and has an air pipe connector at its top.

[0013] Preferably, the top of the mounting bracket is fixedly connected to slide rods on both sides, and the end of the slide rod away from the mounting bracket passes through the upper and lower ends of the slider, and the slider and the slide rod are slidably connected.

[0014] Preferably, a rotary motor is installed in the center of the workbench, and the drive shaft of the rotary motor is connected to the bottom end of the turntable. An electrical control box is installed on one side of the workbench, and the electrical control box is electrically connected to the electric telescopic rod one, the polishing motor, the electric telescopic rod two, the rotary motor, and the magnetic chuck.

[0016] This invention utilizes a turntable, a lock-type weight body, a magnetic chuck, a polishing wheel, and a rotary motor working together to fix the lock-type weight body during polishing, preventing it from moving. Furthermore, since it is not fixed by multiple components, it reduces the probability of damage to the lock-type weight body due to excessive clamping force, thus improving stability.

[0017] By setting up polishing wheel one, polishing motor, electric telescopic rod two, and electric telescopic rod one and polishing wheel two to work together, during polishing, the push rod of electric telescopic rod two extends and retracts to drive polishing wheel one or polishing wheel two to polish the lock-type weight body. The polishing material can be changed according to polishing needs, which is highly flexible and does not require multiple disassembly and replacement, thereby improving polishing efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Referring to Figures 1-4, a stainless steel lock-type weight processing and polishing device includes a worktable 1, a turntable 2 rotatably mounted at the center of the top of the worktable 1, a support frame 5 fixedly connected to the rear of the top of the worktable 1, and a polishing component 6 provided at the top of the support frame 5.

[0026] Referring to Figures 2 and 4, it is further seen that a magnetic suction cup 3 is installed at the top of the turntable 2, and a lock-type weight body 4 is provided at the top of the magnetic suction cup 3. The polishing assembly 6 has two sliders 7. A groove matching the sliders 7 is provided at the center of the upper and lower ends of the support frame 5. The two sliders 7 are slidably installed in the groove at the support frame 5. An electric telescopic rod 8 is fixedly installed at the top of the sliders 7. The push rod end of the electric telescopic rod 8 is connected to a mounting frame 9. Polishing wheel 10 and polishing wheel 2 15 are respectively rotatably installed inside the two mounting frames 9 through a rotating rod. A polishing motor 11 is installed on one side of the mounting frame 9. The rotating rod is close to the polishing motor. One end of the machine 11 is connected to a driven wheel 12. The drive shaft of the polishing motor 11 is equipped with a drive wheel. The outer ring of the drive wheel and the driven wheel 12 is provided with a transmission toothed belt 13. A cleaning air pipe 17 is provided on one side of the top of the worktable 1. The cleaning air pipe 17 is flexible and has an air pipe connector at its top. A rotary motor is installed in the center of the worktable 1. The drive shaft of the rotary motor is connected to the bottom of the turntable 2. An electrical control box 18 is installed on one side of the worktable 1. The electrical control box 18 is electrically connected to the electric telescopic rod 1 8, the polishing motor 11, the electric telescopic rod 2 16, the rotary motor, and the magnetic chuck 3.

[0027] Specifically, the lock-type weight body 4 to be polished can be placed on the top surface of the magnetic chuck 3 as needed. Then, the magnetic chuck 3 is energized, causing the coil inside the magnetic chuck 3 to generate a magnetic field, so that the lock-type weight body 4 is firmly attracted to the top surface of the magnetic chuck 3. After the lock-type weight body 4 is fixed, the polishing motor 11 can be started, which drives the polishing wheel 10 to rotate, thereby polishing the lock-type weight body 4. During the polishing process, since the bottom end of the turntable 2 is connected to the drive shaft of the rotary motor, the rotary motor can be started to drive the magnetic chuck 3 installed on the turntable 2 to rotate, thereby adjusting the position of the lock-type weight body 4. During polishing, the cleaning air pipe 17 can be connected to the cleaning air gun as needed to blow off the small amount of dust generated during polishing.

[0028] Example 2

[0029] Referring to Figures 2, 3, and 4, and based on Embodiment 1, it is further found that the center points of the magnetic chuck 3, polishing wheel 10, and polishing wheel 15 are on the same straight line. Polishing wheel 10 is made of brown corundum material, and polishing wheel 15 is made of leather material. Electric telescopic rods 16 are installed at the center of the front and rear ends of the support frame 5. The drive shafts of the two electric telescopic rods 16 are respectively connected to the two sliders 7. The top of the mounting frame 9 is fixedly connected to the two sides with sliding rods 14. The end of the sliding rod 14 away from the mounting frame 9 passes through the upper and lower ends of the slider 7, and the slider 7 and the sliding rod 14 are slidably connected.

[0030] Specifically, when it is necessary to change the polishing material, since polishing wheel 10 and polishing wheel 2 15 are installed on different mounting brackets 9, the slider 7 can be pushed to slide within the support frame 5 by activating the electric telescopic rod 2 16. This adjusts the contact between polishing wheel 10 or polishing wheel 2 15 and the lock-type weight body 4, allowing for adjustments based on the polishing condition. During the polishing process, personnel can apply an appropriate amount of polishing paste to the lock-type weight body 4 or polishing wheel 10 and polishing wheel 2 15 according to existing technology. The electric telescopic rod 1 8 extends to drive the mounting bracket 9 to rise and fall for close-fitting polishing, allowing for adjustment of the polishing height of polishing wheel 10 or polishing wheel 2 15 as needed. This provides high flexibility in use.

[0031] In actual operation, the lock-type weight body 4 to be polished can be placed on the top surface of the magnetic chuck 3 as needed. Then, the magnetic chuck 3 is energized to generate a magnetic field in the coil inside the magnetic chuck 3, so that the lock-type weight body 4 is firmly attached to the top surface of the magnetic chuck 3. After the lock-type weight body 4 is fixed, the polishing motor 11 can be started to drive the polishing wheel 10 to rotate, thereby polishing the lock-type weight body 4. During the polishing process, since the bottom end of the turntable 2 is connected to the drive shaft of the rotary motor, the rotary motor can be started to drive the magnetic chuck 3 installed on the turntable 2 to rotate, thereby adjusting the position of the lock-type weight body 4. During polishing, the cleaning air pipe 17 can be connected to the cleaning air gun as needed to blow off the small amount of dust generated during polishing.

[0032] When it is necessary to change the polishing material, since polishing wheel 10 and polishing wheel 2 15 are installed on different mounting brackets 9, the slider 7 can be pushed to slide within the support frame 5 by activating the electric telescopic rod 2 16, thereby adjusting the contact between polishing wheel 10 or polishing wheel 2 15 and the lock-type weight body 4. This allows for adjustments based on the polishing condition. During the polishing process, personnel can apply an appropriate amount of polishing paste to the lock-type weight body 4 or polishing wheel 10 and polishing wheel 2 15 according to existing technology. The mounting bracket 9 is then raised and lowered by extending the push rod of the electric telescopic rod 1 8 to perform the polishing. This allows for adjustment of the polishing height of polishing wheel 10 or polishing wheel 2 15 as needed, providing high flexibility in use.

[0033] Afterwards, personnel can use tools to remove the mechanically polished lock weight body 4, and obtain a uniform bright layer by external electrolytic polishing as needed. After polishing, thoroughly clean the residual polishing paste or polishing machine, and wipe it with a lint-free cloth to prevent moisture from corroding the lock weight body 4.

[0034] Furthermore, the control components and modules used for the energized rotation of the polishing motor 11, the energized attraction of the magnetic chuck 3, and the extension and retraction of the electric telescopic rod 18 and the electric telescopic rod 26 are all existing technologies, which can be fully implemented by those skilled in the art and need not be elaborated upon. The content protected by this utility model does not involve improvements to the software and power supply.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
