Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing or industrial automation technology, and in particular relates to a device for grinding the flat surface of parts with height differences by the reciprocating motion of gears and racks. Background Technology

[0002] In industrial production, surface grinders are crucial pieces of equipment, widely used for the precision machining of parts. Traditional surface grinders primarily perform grinding operations using the circumferential surface of the grinding wheel. This grinding method performs excellently when machining parts of equal thickness, ensuring both efficiency and quality. However, with the rapid development of modern manufacturing, the complexity and diversity of parts are increasing, and traditional surface grinders are gradually revealing their limitations when processing parts of varying thicknesses.

[0003] While existing surface grinders perform excellently when grinding parts of the same thickness, they exhibit significant shortcomings when processing parts of varying thicknesses. Specifically, the limitations of existing technology are mainly reflected in the following aspects:

[0004] Limited Grinding Method: Traditional surface grinders primarily rely on the circumferential surface of the grinding wheel for grinding. This limited grinding method restricts their flexibility when processing parts of varying thicknesses. For parts with significant thickness differences, traditional grinders struggle to simultaneously ensure both uniformity and precision in grinding.

[0005] Limited grinding efficiency: When processing parts of different thicknesses, traditional grinding machines require frequent adjustments to grinding parameters and changes to grinding tools, which not only increases the difficulty of operation and labor costs, but also reduces grinding efficiency.

[0006] Unstable machining quality: Due to the limitations of traditional grinding machines when processing parts of varying thicknesses, it is often difficult to guarantee the stability and consistency of machining quality. This may lead to performance degradation or failure of parts during use, affecting the overall quality and reliability of the product.

[0007] Therefore, in order to overcome the shortcomings of existing technologies, designing a small machine that can simultaneously grind parts of different thicknesses and has efficient and stable processing performance has become an urgent problem to be solved. Utility Model Content

[0060] Compared with the prior art, the gear and rack reciprocating motion device of this utility model for grinding the flat surface of parts with height differences has the following technical features and beneficial effects:

[0061] (1) Adjusting the handwheel allows the grinder A and grinder B to be at different heights, enabling the grinding of parts of different thicknesses;

[0062] (2) Because rack A and rack B rotate in different directions, they will make grinder A and grinder B move closer or further away at the same time, which will greatly improve work efficiency.

[0065] (5) Grinding miniaturization brings many advantages. Traditional belt sanders can grind smaller parts, but due to their unique belt sander characteristics, there is no special worktable. When grinding smaller parts, tools are needed, otherwise it is easy to get injured. Due to the characteristics that the parts cannot be fixed, only burrs can be removed or parts with low grinding precision can be ground.

[0066] (6) The dual slide rail mode ensures high grinding precision. This product is mainly used in small mechanical processing enterprises and mold processing manufacturers. This product is practical, simple to process, and modularly designed to meet the daily needs of small companies or single-person operation. Attached Figure Description

[0084] The cutting fluid pump 50 is connected to the cutting fluid storage tank 51; the cutting fluid discharge port 52 is provided on the equipment bracket 1.

[0085] The equipment bracket 1 is equipped with a servo motor switch 45, a grinder switch 46, a cutting fluid switch 47, a power switch 48, and a worktable motor switch 49.

[0086] Technical principle:

[0087] This device utilizes a servo motor 11 to drive a gear 16, which meshes with racks A13 and B14 to form a reciprocating motion mechanism. Racks A13 and B14 slide along rack tracks A2 and B3 respectively, thereby driving the grinding machine slide rails A32 and B53 mounted below them to reciprocate. The grinding machine assembly is connected to the grinding machine slide rails A32 and B53 via grinding machine sliders A31 and B33, and its height can be adjusted as needed to accommodate grinding parts of different heights. Simultaneously, a magnetic worktable 28 can place and fix the parts to be ground. A worktable motor 39 drives a worktable gear 41 to mesh with a worktable rack 36, enabling the worktable to move back and forth, further expanding the grinding range.

[0088] Work process:

[0089] 1. Start-up and preparation:

[0090] Turn on the overall power switch 48 to start the electrical control system 9.

[0091] Adjust the height of the grinding machine assembly by adjusting the handwheel 20 according to the height of the part to be ground, so as to ensure that the grinding wheel 25 is in contact with the surface of the part.

[0092] Place the part to be polished on the magnetic worktable 28 and secure it.

[0093] 2. Workbench adjustment:

[0094] As needed, the slider 43 for moving the worktable back and forth can be adjusted by using the handwheel 44 to move the magnetic worktable 28 back and forth to the appropriate grinding position.

[0095] If left or right movement is required, it can be achieved by sliding the slider 38 on the left and right movement track 37 of the worktable.

[0096] 3. Polishing process:

[0097] Turn on the servo motor switch 45 to start the servo motor 11. The gear 16 starts to rotate and drives the rack A13 and rack B14 to reciprocate along the rack track A2 and rack track B3.

[0098] The grinding machine sliders A31 and B33 move with the reciprocating motion of the grinding machine slide rails A32 and B53, driving the grinding machine assembly to grind the parts.

[0099] During the grinding process, the cutting fluid switch 47 can be turned on as needed. The cutting fluid pump 50 draws the cutting fluid from the cutting fluid storage tank 51 and sprays it onto the grinding area through the cutting fluid discharge hole 52 to cool and lubricate the grinding wheel 25, thereby improving grinding efficiency and the surface quality of the parts.

[0100] 4. Travel control and stopping:

[0101] When racks A13 and B14 touch limit switches A5 and B12 respectively, servo motor 11 rotates in the reverse direction, achieving precise control of reciprocating motion.

[0102] If further polishing is required, the limit switch locking handle 4 can be adjusted to change the position of the limit switch, thereby adjusting the travel range of the reciprocating motion.

[0103] After grinding is completed, turn off the servo motor switch 45, the grinding machine switch 46, the cutting fluid switch 47, and the overall power switch 48 to disconnect the power supply.

[0104] 5. Cleaning and maintenance:

[0105] Clean debris and cutting fluid from the magnetic worktable 28 and the grinding machine assembly.

[0106] Inspect and maintain components such as the grinding wheel 25 and the cutting fluid pump 50 to ensure that the equipment is in good condition.

[0107] Based on the above technical principles and working process, this device can automatically reciprocate grinding the flat surfaces of parts with varying heights, improving grinding efficiency and precision, and meeting the needs of modern manufacturing for high-precision parts.

[0108] Example 2

[0109] This is either a new embodiment or a supplement to Embodiment 1.

[0110] This embodiment, based on Embodiment 1, further includes a worktable positioning support 40, a bottom partition plate 42, and a worktable bracket 54. The left and right moving rails 37 of the worktable are laterally connected to the equipment bracket 1 via the worktable bracket 54. The worktable positioning support 40 is located below the worktable bracket 54 and connected to the equipment bracket 1. The bottom partition plate 42 is mounted on the equipment bracket 1. The worktable positioning support 40 enhances stability: Located below the worktable bracket 54 and connected to the equipment bracket 1, the worktable positioning support 40 enhances the stability of the worktable during lateral movement, preventing swaying or deviation due to excessive load or excessive moving speed. It improves accuracy: The positioning support ensures higher accuracy when the worktable moves to a designated position, which is crucial for parts requiring precise grinding. It extends service life: The positioning support distributes the weight of the worktable and its load, reducing the burden on the equipment bracket 1 and other structures, thereby extending the service life of the entire equipment.

[0111] Advantages of the bottom panel 42: Protecting the internal structure: The bottom panel 42, mounted on the equipment bracket 1, protects the internal structure of the equipment, preventing dust, debris, and other contaminants from entering and causing damage or malfunction. Facilitating maintenance: The design of the bottom panel 42 makes equipment maintenance more convenient. When cleaning or repairing the equipment, the bottom panel can be easily removed to expose the internal structure. Enhancing aesthetics: The bottom panel also improves the appearance of the equipment, making it look cleaner and more professional.

[0112] Benefits of the worktable support 54: Enhanced support capacity: As the supporting structure for the left and right moving rails 37 of the worktable, the worktable support 54 enhances the support capacity of the rails, ensuring the stability and safety of the worktable during lateral movement. Increased flexibility: By adjusting the position and height of the worktable support 54, the position and angle of the worktable can be flexibly adjusted to adapt to the grinding needs of parts of different sizes and shapes. Easy installation and disassembly: The design of the worktable support 54 makes the installation and disassembly of the worktable more convenient, allowing for quick adjustment and reconfiguration of the equipment according to actual needs.

[0113] Turn on the power switch 48 to connect the power supply; turn on the grinder switch 46, and both motors of grinders A18 and B19 will start running simultaneously, driving the grinding wheels to rotate; turn on the servo motor switch 45, and the servo motor 11 will start running, driving the gear 16 to move, and simultaneously driving the racks A13 and B14 to move away or closer to each other. The gears and racks drive the rack slide rail 15 to reciprocate within the rack rails A2 and B3; 5 is a limit switch, and the limit switch locking handle 4 can control the limit opening. The grinding wheel slides within the track, adjusting the reciprocating distance. The limit switch locking handle 4 locks the limit switch 5. Adjusting the handwheel 20 adjusts the height of grinding machines A18 and B19, allowing for separate grinding of equipment of different thicknesses. The grinding machine mounting bracket 22 secures grinding machine 19. The grinding machine adjusting slider 23 adjusts the up-and-down movement of the grinding machine. The grinding machine up-and-down adjusting track 24 ensures the grinding wheel remains horizontal with the magnetic worktable 28 during up-and-down movement. Cooling is required during grinding; therefore, the cutting fluid switch 47 is activated to prevent excessive deformation.

[0114] The grinder slide rail A32 is connected to the rack and pinion track A2; the grinder slider A31 is connected to both the grinder slide rail A32 and the grinder slide rail B53. The slider locking handle A30 can firmly lock the slider onto the grinder slide rail A32, while the grinder slide rail B53 can slide normally; the grinder slider B33 is also connected to both the grinder slide rail A32 and the grinder slide rail B53. The slider locking handle B34 can firmly lock the slider onto the grinder slide rail B53, but it can slide normally on the grinder slide rail A32.

[0115] The magnetic worktable 28 and the worktable rack 36 are integrated. When the worktable motor 49 is started, the worktable gear 41 drives the worktable rack 36 to move left and right. The worktable is fixed on the slider 38, and the worktable can rotate left and right on the slide rail 37. The slide rail 37 is fixed on the worktable support 24. The worktable support 24 is connected to the worktable positioning support 40. The worktable motor 39 is fixed on the worktable front and back moving slider 43, and 54 is also fixed on the worktable front and back moving slider 43. When the handwheel 44 is turned, the handwheel can drive the worktable front and back moving slider 43 to move back and forth.

[0116] This invention achieves reciprocating motion of the grinding device through the meshing connection of a servo motor-driven gear and rack. Combined with a height-adjustable grinding machine assembly, it can precisely adapt to parts with varying heights, significantly improving grinding efficiency and precision. Furthermore, the meshing connection between the worktable motor and the worktable rack allows the magnetic worktable to move flexibly forward, backward, left, and right, further expanding the grinding range and enhancing the equipment's practicality.

[0117] This invention also ensures the stability and safety of the grinding process by adding limit switches, telescopic cover rubber strips, and a cutting fluid system, effectively protecting the internal structure of the equipment and reducing maintenance costs. Meanwhile, the multiple switches on the equipment bracket make operation simpler and easier to control, providing a more reliable and efficient solution for the precision grinding of flat surfaces of parts with varying heights.

[0118] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
