Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a C-shaped adjustment mechanism for an optical curve grinder. Background Art

[0002] In the field of modern machining, grinding machines, as precision machining equipment, have a direct impact on product quality and production costs due to their performance and efficiency. Many grinding operations, especially those involving complex curved surfaces or unusual shapes, require the grinding wheel to move flexibly and precisely along a predetermined trajectory to achieve comprehensive and uniform grinding of the workpiece surface. Traditionally, this complex arc-shaped motion relies primarily on the coordinated control of X- and Z-axis linear motors.

[0003] However, the existing technology uses a combination of X-axis and Z-axis linear motors to drive the grinding wheel, which can basically meet the processing requirements of arc trajectories, but has several significant technical bottlenecks and shortcomings:

[0004] 1. High-precision coordination requirements: To achieve precise arc trajectories, the X-axis and Z-axis linear motors must work in close coordination, placing extremely high demands on the control system's algorithm accuracy, response speed, and inter-motor synchronization. Any slight deviation can lead to a decrease in machining accuracy and affect product quality.

[0005] 2. High programming complexity: In order to control the grinding wheel to move along a predetermined arc trajectory, a complex program needs to be written in the grinding machine control system, including trajectory planning, speed control, acceleration adjustment and other links. This not only increases the programming difficulty, but also prolongs the debugging cycle.

[0006] 3. High manufacturing costs: The use of high-precision linear motors and complex control system design significantly increase the manufacturing cost of grinding machines. For small and medium-sized enterprises, the high equipment investment may become an unbearable burden.

[0007] 4. Difficulty in maintenance: The multi-axis collaborative control system involves the precise coordination of multiple components. Once a fault occurs, it is difficult to troubleshoot and repair, which affects production efficiency and equipment utilization. Utility Model Content

[0010] A fixing seat, wherein both sides of the fixing seat are provided with C-shaped grooves;

[0011] A movable seat, the movable seat being slidably arranged in front of the fixed seat, and both sides of the movable seat are connected with C-shaped guide protrusions adapted to the C-shaped groove;

[0012] The adjusting drive device is installed between the fixed seat and the movable seat, and the adjusting drive device can drive the movable seat to move back and forth along the direction of the C-shaped groove and the C-shaped guide protrusion.

[0016] Furthermore, the C-shaped adjustment mechanism of the grinding machine platform also includes:

[0017] The locking device is installed on one side of the movable seat and can move synchronously with the movable seat.

[0018] Furthermore, the adjustment drive device includes a C-shaped tooth plate installed on the rear side of the movable seat, a transmission shaft rotatably connected to the inside of the fixed seat, and an adjustment drive motor installed on the top of the fixed seat. The bottom of the transmission shaft is connected to a worm gear engaged with the C-shaped tooth plate, and the driving end of the adjustment drive motor and the driven end of the transmission shaft are connected by a belt drive structure.

[0019] Furthermore, the belt transmission structure includes an active synchronous wheel installed on the driving end of the adjustment drive motor and a driven synchronous wheel installed on the driven end of the transmission shaft. The exteriors of the active synchronous wheel and the driven synchronous wheel are commonly connected to a synchronous belt.

[0020] Furthermore, the surface of the C-shaped groove is provided with a limiting groove and a plurality of pin holes, and the plurality of pin holes are evenly distributed along the shape of the C-shaped groove.

A through hole is opened inside the C-shaped seat and corresponds to the position of each cylinder. When locking, the pin shaft is inserted into the through hole and one of the pin holes.

[0022] The utility model provides a C-shaped adjustment mechanism for an optical curve grinder. Compared with the prior art, it has the following advantages:

[0023] The C-shaped adjustment mechanism of the grinding machine significantly improves the flexibility and accuracy of the position adjustment of the grinding wheel during the grinding process by adopting an innovative C-shaped trajectory adjustment drive device. Specifically, the mechanism uses an adjustment drive motor to drive the worm to engage with the C-shaped tooth plate, thereby realizing the smooth reciprocating movement of the movable seat and the grinding wheel mounted thereon along the "C"-shaped trajectory. Combined with the synchronous lifting function of the linear motor module in the vertical direction, a multi-dimensional adjustment capability is formed. This design not only simplifies the complexity of the traditional multi-axis linear motor collaborative control, reduces the programming difficulty and manufacturing cost, but also ensures high processing accuracy and stability through the precise worm tooth plate transmission mechanism. In addition, the ingenious combination of the C-shaped groove and the guide protrusion further enhances the smoothness and reliability of the movable seat movement, effectively improving the durability of the overall structure.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention and are not examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-8 The utility model provides a technical solution: a C-shaped adjustment mechanism of an optical curve grinder, which is composed of a fixed seat 1, a movable seat 2, a linear motor module 3, a grinding drive motor 4, an adjustment drive device 5 and a locking device 6. Among them, the fixed seat 1 and the movable seat 2 are two relatively independent individuals, that is, they can slide relative to each other, and the power source for achieving relative sliding is the adjustment drive device 5 installed between the fixed seat 1 and the movable seat 2. The adjustment drive device 5 can drive the movable seat 2 to move back and forth along a "C"-shaped trajectory. The linear motor module 3 is installed on the front side of the movable seat 2, and the grinding drive motor 4 is installed on the driving end (linear The specific structure and working principle of the motor module 3 are existing well-known technologies and will not be described in detail here), and the driving end of the grinding drive motor 4 is installed with a grinding wheel 41. The linear motor module 3 can drive the grinding drive motor 4 and the grinding wheel 41 to rise and fall synchronously. That is to say, when the position of the grinding wheel 41 is adjusted, in addition to being able to move back and forth in a "C"-shaped trajectory, it can also move back and forth in the vertical direction. In addition, in order to ensure the stability of the movable seat 2 in the reciprocating movement, C-shaped grooves 11 are opened on both sides of the fixed seat 1, and C-shaped guide protrusions 21 that are compatible with the C-shaped grooves 11 are connected to both sides of the movable seat 2. The guide protrusions 21 slide inside the C-shaped grooves 11;

[0035] Specifically, the adjustment drive device 5 includes a C-shaped toothed plate 51 mounted on the rear side of the movable seat 2, a transmission shaft 52 rotatably connected to the interior of the fixed seat 1, and an adjustment drive motor 53 (the adjustment drive motor 53 is a servo motor) mounted on the top of the fixed seat 1. The bottom of the transmission shaft 52 is connected to a worm 54 meshing with the C-shaped toothed plate 51. The driving end of the adjustment drive motor 53 and the driven end of the transmission shaft 52 are connected via an active synchronous wheel 55, a driven synchronous wheel 56, and a synchronous belt 57.

[0036] When the adjustment drive device 5 is used to adjust the position of the movable seat 2, the adjustment drive motor 53 drives the active synchronous wheel 55, the synchronous belt 57, and the driven synchronous wheel 56 to rotate in turn, thereby driving the overall synchronous rotation of the transmission shaft 52 and the worm 54. Since the worm 54 is engaged with the C-shaped tooth plate 51, when the worm 54 rotates, the C-shaped tooth plate 51 will deflect clockwise or counterclockwise, thereby driving the overall synchronous deflection of the movable seat 2, the linear motor module 3, the grinding drive motor 4 and the grinding wheel 41, and finally realizing the position adjustment of the grinding wheel 41, that is, it is possible to grind different positions of the workpiece.

[0037] In addition, when the position adjustment of the grinding wheel disc 41 is completed, in order to prevent the grinding wheel disc 41 from moving under the action of gravity, a locking device 6 is provided. The locking device 6 is installed on one side of the movable seat 2 and can move synchronously with the movable seat 2, and the surface of the C-shaped groove 11 is respectively provided with a limiting groove 12 and a plurality of pin holes 13, and the plurality of pin holes 13 are evenly distributed along the shape of the C-shaped groove 11. In addition, the locking device 6 includes a C-shaped seat 61 fixedly connected to the movable seat 2, and the inner edge of the C-shaped seat 61 is connected with a C-shaped limiting convex edge 62, and the C-shaped limiting convex edge 62 is engaged with the inside of the limiting groove 12. Two cylinders 64 are installed on the outside of the C-shaped seat 61, and a pin shaft 65 is installed at the telescopic end of each cylinder 64. A through hole 63 is provided inside the C-shaped seat 61 and at the position corresponding to each cylinder 64. When locked, the pin shaft 65 is inserted into the through hole 63 and one of the pin holes 13;

[0038] When locking is required, the two cylinders 64 extend, thereby pushing the end of the pin 65 into one of the pin holes 13. Since the pin hole 13 is opened on the surface of the fixed seat 1 and the fixed seat 1 is fixed, when the pin 65 is inserted, the C-shaped seat 61 connected to the cylinder 64 is locked and constrained. Similarly, the movable seat 2 connected to the C-shaped seat 61 is also locked and constrained. Finally, the position of the grinding wheel 41 cannot change autonomously.
