Jig grinding machine for mold processing

Abstract

This utility model belongs to the field of grinding machine technology, specifically relating to a vibration-damping grinding machine for mold processing. The vibration-damping grinding machine includes a base, with a U-shaped plate fixedly connected to the upper surface of the base. A first circular hole is formed on the upper surface of the U-shaped plate, and a guide sleeve is fixedly connected to the inner wall of the first circular hole. The vibration-damping grinding machine can control the movement of a second cylinder on a first cylinder via a lifting mechanism. Simultaneously, when the second cylinder moves up or down, the friction between the arc-shaped plate and the hollow damping column changes through the cooperation of the trapezoidal groove and trapezoidal block. Therefore, when the vibration of the vibration-damping grinding machine is severe, the friction between the arc-shaped plate and the hollow damping column can be increased to improve energy consumption. When the vibration of the vibration-damping grinding machine is slight, the friction between the arc-shaped plate and the hollow damping column can be reduced to avoid rigid impact caused by excessive damping, ensuring stable operation of the vibration-damping grinding machine.

Description

Technical Field

[0001] This utility model belongs to the field of grinding technology, specifically relating to a vibration-damping grinding machine for mold processing. Background Technology

[0002] In the field of mold processing, the machining accuracy of grinding machines directly determines the quality of molds, and the vibration generated during the operation of grinding machines is one of the key factors affecting machining accuracy. Especially in high-precision mold processing, even a small vibration can lead to excessive surface roughness, increased dimensional errors, or even mold scrapping.

[0003] Currently, anti-vibration grinding machines on the market utilize the elastic deformation of springs to absorb vibration energy, and the friction between the damping column and the sleeve effectively dissipates the kinetic energy of the grinding machine's vibration, reducing the transmission and amplification of vibration. However, since the friction between the sleeve and the damping column is fixed, it cannot be adaptively adjusted according to the vibration intensity. When the grinding machine vibrates violently, the energy dissipation capacity of the fixed damping is insufficient, making it difficult to effectively absorb and dissipate vibration energy, causing the vibration to be continuously transmitted to the worktable and workpiece, seriously affecting the processing stability. Conversely, when the vibration is mild, the fixed damping is prone to excessive suppression, triggering rigid impacts, which not only exacerbates the wear of equipment components but may also react on the workpiece, causing secondary accuracy errors.

[0004] Meanwhile, replacing the vibration damping pads at the bottom of the grinding machine is quite troublesome because the grinding machine needs to be raised to a certain height before the replacement can be done. Utility Model Content

[0005] The purpose of this invention is to provide a vibration-damping grinding machine for mold processing, which solves the problem that the damping force of existing vibration-damping grinding machines cannot be adaptively adjusted according to the vibration intensity. At the same time, it also solves the problem that when replacing the vibration-damping rubber pads at the bottom of the grinding machine, the grinding machine needs to be raised to a specified height before it can be replaced.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A vibration-damping grinding machine for mold processing includes a base. A U-shaped plate is fixedly connected to the upper surface of the base. A first circular hole is formed on the upper surface of the U-shaped plate. A guide sleeve is fixedly connected to the inner wall of the first circular hole. A sliding column is slidably connected to the inner wall of the guide sleeve. A spring is fixedly connected to the bottom of the sliding column and the upper surface of the base. A hollow damping column is bonded to the surface of the sliding column. A worktable is fixedly connected to the upper surface of the sliding column. A grinding machine bed is fixedly connected to the upper surface of the worktable. A first cylinder is fixedly connected to the upper surface of the U-shaped plate. Rectangular holes are formed on both the left and right sides of the first cylinder. Arc-shaped plates are fitted to the inner walls of the rectangular holes and the left and right sides of the hollow damping columns. Trapezoidal grooves are formed on the sides of the arc-shaped plates. A second cylinder is fitted onto the surface of the first cylinder. A trapezoidal block is fixedly connected to the inner wall of the second cylinder. The surface of the trapezoidal block is fitted to the inner wall of the trapezoidal groove. A lifting mechanism is fixedly connected to the surface of the second cylinder and the upper surface of the base.

[0008] The present invention is further configured such that the lifting mechanism includes a motor base, a stepper motor, a threaded column, a first threaded cylinder, and a connecting bracket. The bottom of the motor base is fixedly connected to the upper surface of the base, the upper surface of the motor base is fixedly connected to the bottom of the stepper motor, the output end of the stepper motor is fixedly connected to the bottom end of the threaded column through a coupling, the surface of the threaded column is threadedly connected to the inner wall of the first threaded cylinder, and the surfaces of the first threaded cylinder and the second cylinder are both fixedly connected to the inner wall of the connecting bracket.

[0009] The present invention is further configured such that the axis of the arc-shaped plate coincides with the axis of the hollow damping column, and the inner wall radius of the arc-shaped plate is equal to the radius of the hollow damping column.

[0010] The present invention is further configured such that the trapezoidal block and the trapezoidal groove are fitted with a clearance, and the bottom surface of both the trapezoidal block and the bottom surface of the trapezoidal groove are inclined surfaces.

[0011] The present invention is further configured such that: a second circular hole is provided inside the base; a hollow cylinder is fitted to the inner wall of the second circular hole; a shock-absorbing pad is adhered to the bottom of the hollow cylinder; a second threaded cylinder is fixedly connected to the inner wall of the hollow cylinder; a baffle is fitted to the upper surface of the second threaded cylinder; a third circular hole is provided inside the baffle; bolts are fitted to the inner wall of the third circular hole and the upper surface of the baffle; the surface of the bolts is threadedly connected to the inner wall of the second threaded cylinder; a positioning ring is fitted onto the surface of the baffle; and the bottom of the positioning ring is fixedly connected to the upper surface of the base.

[0012] The present invention is further configured such that the cross-section of the shock-absorbing rubber pad is circular, the axis of the shock-absorbing rubber pad coincides with the axis of the hollow cylinder, and the diameter of the hollow cylinder is larger than the diameter of the shock-absorbing rubber pad.

[0013] The technical effects achieved by this utility model are as follows:

[0014] The anti-vibration grinding machine for mold processing of this utility model can control the movement of the second cylinder on the first cylinder through a lifting mechanism. At the same time, when the second cylinder moves up or down, the friction between the arc plate and the hollow damping column can be changed through the cooperation of the trapezoidal groove and the trapezoidal block. Thus, when the anti-vibration grinding machine vibrates violently, the energy consumption effect can be improved by increasing the friction between the arc plate and the hollow damping column. When the vibration of the anti-vibration grinding machine is slight, the friction between the arc plate and the hollow damping column can be reduced to avoid rigid impact caused by excessive damping and ensure the smooth operation of the anti-vibration grinding machine.

[0015] This utility model of a vibration-damping grinding machine for mold processing effectively prevents ground vibration from being transmitted into the grinding machine by setting a shock-absorbing rubber pad at the bottom of the base. At the same time, through the cooperation of a hollow cylinder, a second threaded cylinder, a baffle, a third circular hole, bolts and a positioning ring, the user can quickly disassemble and assemble the shock-absorbing rubber pad at the bottom of the base by rotating the bolts on the top of the base, making it more convenient to replace the shock-absorbing rubber pad.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1 to 11As shown, a vibration-damping grinding machine for mold processing includes a base 1. A U-shaped plate 2 is fixedly connected to the upper surface of the base 1. A first circular hole 3 is opened on the upper surface of the U-shaped plate 2. A guide sleeve 4 is fixedly connected to the inner wall of the first circular hole 3. A sliding column 5 is slidably connected to the inner wall of the guide sleeve 4. Springs 6 are fixedly connected to the bottom of the sliding column 5 and the upper surface of the base 1. A hollow damping column 7 is bonded to the surface of the sliding column 5. A worktable 8 is fixedly connected to the upper surface of the sliding column 5. A grinding machine bed 9 is fixedly connected to the upper surface of the worktable 8. The upper surface of the U-shaped plate 2 is fixedly connected to the base 1. A first cylinder 10 is fixedly connected. Rectangular holes 11 are provided on both the left and right sides of the first cylinder 10. Arc plates 12 are attached to the inner wall of the rectangular holes 11 and the left and right sides of the hollow damping column 7. Trapezoidal grooves 13 are provided on the side of the arc plates 12. A second cylinder 14 is fitted on the surface of the first cylinder 10. A trapezoidal block 15 is fixedly connected to the inner wall of the second cylinder 14. The surface of the trapezoidal block 15 is attached to the inner wall of the trapezoidal groove 13. A lifting mechanism 16 is fixedly connected to the surface of the second cylinder 14 and the upper surface of the base 1.

[0034] The lifting mechanism 16 includes a motor base 161, a stepper motor 162, a threaded column 163, a first threaded cylinder 164, and a connecting bracket 165. The bottom of the motor base 161 is fixedly connected to the upper surface of the base 1, and the upper surface of the motor base 161 is fixedly connected to the bottom of the stepper motor 162. The output end of the stepper motor 162 is fixedly connected to the bottom end of the threaded column 163 through a coupling. The surface of the threaded column 163 is threadedly connected to the inner wall of the first threaded cylinder 164. The surfaces of the first threaded cylinder 164 and the second cylinder 14 are both fixedly connected to the inner wall of the connecting bracket 165.

[0035] The axis of the arc plate 12 coincides with the axis of the hollow damping column 7, and the inner radius of the arc plate 12 is equal to the radius of the hollow damping column 7.

[0036] The trapezoidal block 15 and the trapezoidal groove 13 are fitted with a clearance, and the bottom surfaces of both the trapezoidal block 15 and the trapezoidal groove 13 are inclined surfaces.

[0037] It should be noted that, through the cooperation of the guide sleeve 4 and the slide column 5, the worktable 8 can only move up or down. The slide column 5 is supported by the spring 6. When the grinding machine bed 9 vibrates, the elastic deformation of the spring 6 absorbs the vibration energy. In addition, the friction between the hollow damping column 7 and the arc plate 12 can effectively consume the kinetic energy of the grinding machine bed 9 when it vibrates, reducing the transmission and amplification of vibration.

[0038] When the stepper motor 162 drives the threaded column 163 to rotate, the connecting bracket 165 can move up or down through the cooperation of the threaded column 163 and the first threaded cylinder 164. When the connecting bracket 165 drives the second cylinder 14 to move down, the pressure of the arc plate 12 on the hollow damping column 7 can be increased through the trapezoidal groove 13 and the inclined surface at the bottom of the trapezoidal block 15, and the friction between the arc plate 12 and the hollow damping column 7 can be increased. When the connecting bracket 165 drives the second cylinder 14 to move up, the pressure of the arc plate 12 on the hollow damping column 7 can be reduced as the second cylinder 14 moves up.

[0039] like Figures 1 to 13 As shown, the base 1 has a second circular hole 17 inside, and a hollow cylinder 18 is attached to the inner wall of the second circular hole 17. A shock-absorbing pad 19 is attached to the bottom of the hollow cylinder 18. A second threaded cylinder 20 is fixedly connected to the inner wall of the hollow cylinder 18. A baffle 21 is attached to the upper surface of the second threaded cylinder 20. A third circular hole 22 is opened inside the baffle 21. Bolts 23 are attached to both the inner wall of the third circular hole 22 and the upper surface of the baffle 21. The surface of the bolts 23 is threaded to the inner wall of the second threaded cylinder 20. A positioning ring 24 is sleeved on the surface of the baffle 21. The bottom of the positioning ring 24 is fixedly connected to the upper surface of the base 1.

[0040] The shock-absorbing pad 19 has a circular cross-section, and its axis coincides with the axis of the hollow cylinder 18. The diameter of the hollow cylinder 18 is larger than the diameter of the shock-absorbing pad 19.

[0041] It should be noted that by setting the shock-absorbing rubber pad 19 at the bottom of the base 1, the vibration of the ground can be effectively prevented from being transmitted into the grinding machine. When the baffle 21 is inserted into the positioning ring 24, the baffle 21 can be positioned by the positioning ring 24. When the bolt 23 passes through the third round hole 22 and is screwed into the second threaded cylinder 20, the baffle 21 can be fixed on the hollow cylinder 18 by the cooperation of the bolt 23 and the second threaded cylinder 20. The shock-absorbing rubber pad 19 can be fixed at the bottom of the base 1 by the cooperation of the baffle 21, the positioning ring 24, the hollow cylinder 18 and the second round hole 17. When the bolt 23 is unscrewed from the second threaded cylinder 20, the hollow cylinder 18 can be directly separated from the base 1 by moving the baffle 21 out of the positioning ring 24.

[0042] The working principle of this utility model is as follows: when the grinding machine bed 9 vibrates, the elastic deformation of the spring 6 absorbs the vibration energy, and the friction between the hollow damping column 7 and the arc plate 12 can effectively consume the kinetic energy of the grinding machine bed 9 when it vibrates, thereby reducing the transmission and amplification of vibration.

[0043] When the grinding machine bed 9 vibrates violently, the stepper motor 162 drives the threaded column 163 to rotate clockwise. Through the cooperation of the threaded column 163 and the first threaded cylinder 164, the connecting bracket 165 can move downward. When the connecting bracket 165 drives the second cylinder 14 to move downward, the pressure of the arc plate 12 on the hollow damping column 7 can be increased through the trapezoidal groove 13 and the inclined surface at the bottom of the trapezoidal block 15, and the friction between the arc plate 12 and the hollow damping column 7 can be increased. At this time, by increasing the friction between the arc plate 12 and the hollow damping column 7, the energy consumption effect is improved.

[0044] When the vibration of the grinding machine bed 9 is slight, the stepper motor 162 drives the threaded column 163 to rotate counterclockwise. Through the cooperation of the threaded column 163 and the first threaded cylinder 164, the connecting bracket 165 can move upward. When the connecting bracket 165 drives the second cylinder 14 to move upward, the pressure of the arc plate 12 on the hollow damping column 7 can be reduced as the second cylinder 14 moves upward. At this time, by reducing the friction between the arc plate 12 and the hollow damping column 7, rigid impact caused by excessive damping is avoided, and the anti-vibration grinding machine runs smoothly.

[0045] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
