Description

Technical Field

[0001] This invention relates to the field of grinding technology, and in particular to a grinding apparatus for precision parts machining. Background Technology

[0002] Currently, most precision grinding equipment uses a single integrated electromagnetic chuck to fix the workpiece, relying solely on the force applied to the bottom of the workpiece for clamping. When grinding long parts on a flat surface, the workpiece is prone to shifting during the grinding feed process, resulting in a large variation in the processing dimensions. For relevant prior art, please refer to the prior art document (CN122353378A) for an electromagnetic grinding chuck device, comprising: a grinding spindle, the top of which is fixedly connected to the output shaft of a rotary motor; a mounting base, coaxially fixedly disposed at the bottom of the grinding spindle, the mounting base having at least three grooves evenly distributed along the circumferential direction; a mounting rod, slidably disposed in each groove, a grinding block disposed on the side of the mounting rod away from the center of the mounting base; a centrifugal drive rod, one end of which is hinged to the end of the mounting rod near the center of the mounting base, the other end of which is hinged to a central slider, the central slider being slidably sleeved on the grinding spindle along the axial direction and located directly above the mounting base; and a constant pressure spring, sleeved on the grinding spindle, one end of which abuts against the lower end of the central slider, the other end of which abuts against the... The mounting base is located at the top; wherein the constant pressure spring is always in a compressed state, applying a constant upward preload force to the central slider; in the static state, the constant pressure spring pushes the central slider upward along the grinding spindle, and drives all the mounting rods to slide along the groove towards the center of the mounting base through the centrifugal drive rod, so that all the grinding blocks are gathered to the minimum diameter position; when the grinding spindle rotates, the radial centrifugal force generated by the grinding blocks and the mounting rods overcomes the gathering force of the constant pressure spring, and drives the mounting rods to slide along the groove away from the center of the mounting base, so that the grinding blocks are attached to the inner wall of the hole of the sheet metal part to be ground; during the grinding process, the spring force of the constant pressure spring and the centrifugal force are dynamically balanced through the lever action of the centrifugal drive rod, so that the grinding blocks maintain a constant grinding pressure on the inner wall of the hole; The existing grinding fixtures rely solely on the single-sided adsorption and fixation of the workpiece bottom surface. However, the grinding operation causes the parts to vibrate and shift easily, or even cause uneven stress resulting in deformation and indentation, leading to poor grinding quality and even increasing production costs. Therefore, how to provide a grinding device for precision parts processing is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] One objective of this invention is to provide a grinding apparatus for precision parts processing. This invention can clamp parts at multiple points, unlike relying solely on the bottom surface of the workpiece for single-sided adsorption and fixation. During the grinding process, the pressure is evenly distributed to all parts of the part, which can reduce damage to the part. At the same time, because the electric push rod is set on the grinding path, the electric push rod can further reduce the possibility of part movement during the grinding process, increase the stability of the part during the grinding process, and improve its grinding quality.

[0004] A grinding apparatus for precision parts machining according to an embodiment of the present invention includes a grinding chamber and a feed slide mechanism for moving parts inside the grinding chamber. The grinding chamber is equipped with a grinding mechanism for grinding the parts. The grinding mechanism includes a fixed base mounted on the inner wall of the grinding chamber and a grinding machine mounted on the fixed base. The feed slide mechanism uses a workpiece adsorption platform to move the parts inside the grinding chamber and grinds them using the grinding machine. The apparatus further includes: The frame assembly includes a main frame that moves with the workpiece adsorption platform during grinding and moves relative to the workpiece adsorption platform during non-grinding processes. Stabilizing components include multiple sets of electric actuators mounted on the main frame and arranged along the grinding path; A laser emitter is installed on the inner wall of one side of the grinding chamber, and the grinding chamber has a receiving surface for receiving the positioning beam on the side opposite to the laser emitter. The baffle plate and the electric actuator are located on opposite sides of the main frame. When the baffle plate moves with the electric actuator to the sensing area of ​​the position sensor, it outputs a signal. A piston assembly is located between the electric actuator and the main frame. The bottom of the piston assembly is connected to a sleeve via a delivery hose, and the sleeve is fitted onto the output end of the electric actuator. The positioning block, which is matched with the electric actuator and is installed at the output end of the electric actuator, determines whether the positioning beam emitted by the laser emitter can penetrate all the positioning blocks and be projected onto the receiving surface of the grinding chamber when the part to be ground is pressed down.

[0005] Preferably, the feed slide mechanism includes a drive module and a guide slide, wherein the drive module is connected to the guide slide and drives the guide slide to reciprocate.

[0006] Preferably, the workpiece adsorption platform is mounted on a guide slide and moves with it.

[0007] Preferably, the fixed base is fixed to the inner wall of the grinding chamber, and the grinding machine is mounted on the fixed base using a fastening structure.

[0008] Preferably, the frame assembly further includes frame limiting slides installed at both ends of the workpiece adsorption stage, wherein the bottom ends of the main frame slide inside the frame limiting slides. The upper part of the main frame is provided with a transverse through beam that passes through the fixed base, and the fixed base has multiple holes for the transverse through beam to pass through.

[0009] Preferably, the stabilizing component further includes a bracket mounting base and a guide bracket that is fixedly connected to the main frame via the bracket mounting base. The electric actuator is fixed to one side of the guide bracket, and the output end of the electric actuator is equipped with a guide structure that moves along the guide bracket.

[0010] Preferably, the output end of the electric actuator is provided with a pressure head, and the pressure head has a built-in pressure sensing unit; The pressure sensor unit sets the output pressure for all electric actuators uniformly, so that each group of pressure heads presses the parts with the same preset pressure.

[0011] Preferably, the piston component is divided into a piston cylinder and a piston rod, and the piston rod is connected to the output end of the electric actuator via a connecting rod.

[0012] Preferably, the bottom of the sleeve is provided with a nozzle surrounding the outside of the pressure head.

[0013] Preferably, one side of the positioning block is fixed with an ear for connecting to the output end of the electric actuator.

[0014] The beneficial effects of this invention are: This invention can activate electric actuators, using the pressure head on the output end of the electric actuators to press against the surface of the part. Utilizing a design with multiple sets of electric actuators, it can fix the part to be ground differently from the aforementioned workpiece adsorption platform, and can press the part at multiple points, unlike relying solely on the bottom surface of the workpiece for single-sided adsorption and fixation. During the grinding process, the pressure is evenly distributed to all parts of the part, reducing damage. Furthermore, because the electric actuators are positioned along the grinding path, they further reduce the possibility of part movement during the grinding process, increasing the stability of the part during grinding and improving its grinding quality. In this invention, when one of the electric push rods approaches the grinding tool, the sensing range of the baffle plate path position sensor on the opposite side of one of the electric push rods is activated. At this time, the output end of the electric push rod can be controlled to lift up to cancel the clamping of the part. Compared with Embodiment 1, where the preset clamping time or preset part movement position is reached, the timing of the electric push rod lifting in this embodiment is more precise. At the same time, the time from the next baffle plate path position sensor to control the electric push rod to lift up can be recorded to detect whether the part movement speed is compliant, avoiding large fluctuations in the part movement speed that could affect the grinding quality. When the electric actuator drives the pressure head to move and contact the part for pressing, the gas stored inside the piston component is extracted and discharged through the nozzle on the sleeve. During the process of the pressure head moving and contacting the part for pressing, the cutting fluid or impurities directly below the pressure head can be blown away and exposed to the surface of the part, or impurities can be blown away to keep the pressing surface between the pressure head and the part clean, so as to prevent impurities from being squeezed and damaging the part by the pressure head. At the same time, it can avoid the implementation of the above embodiment from being affected by impurities. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0018] Example 1: refer to Figures 1 to 4 The system includes a grinding chamber 1 and a feed slide mechanism 2 that moves parts within the grinding chamber 1. The grinding chamber 1 is equipped with a grinding mechanism 3 for grinding the parts. The grinding mechanism 3 includes a fixed base 31 mounted on the inner wall of the grinding chamber 1 and a grinding machine 32 mounted on the fixed base 31. The feed slide mechanism 2 uses a workpiece adsorption platform 4 to move the parts within the grinding chamber 1 and grinds them using the grinding machine 32. The system also includes: a frame assembly, including a main frame 510 that moves with the workpiece adsorption platform 4 during grinding and moves relative to the workpiece adsorption platform 4 during non-grinding processes; and a stabilizing assembly, including multiple sets of electric push rods 522 mounted on the main frame 510 and arranged along the grinding path. The feed slide mechanism 2 includes a drive module and a guide slide. The drive module connects to the guide slide and drives the guide slide to reciprocate. The workpiece adsorption platform 4 is mounted on the guide slide and moves with it. The fixed base 31 is fixed to the inner wall of the grinding chamber 1. The grinding machine 32 is mounted on the fixed base 31 using a fastening structure. The frame assembly also includes frame limiting slides 512 installed at both ends of the workpiece adsorption platform 4. The bottom ends of the main frame 510 slide inside the frame limiting slides 512. A transverse through beam 511 is mounted on the upper part of the main frame 510 and passes through the fixed base 31. The fixed base 31 has multiple holes for the transverse through beam 511 to pass through. The stabilizing assembly also includes a bracket mounting base 520 and a guide bracket 521 fixedly connected to the main frame 510 using the bracket mounting base 520. An electric push rod 522 is fixed on one side of the guide bracket 521, and the output end of the electric push rod 522 is equipped with a guide structure that moves along the guide bracket 521. In this embodiment, the position of the grinding machine 32 on the fixed base 31 is adjusted according to the specifications of the part to be ground. After the adjustment is completed, the part to be ground is placed on the workpiece adsorption platform 4 at the grinding position, and then fixed by the workpiece adsorption platform 4. Finally, the drive module and guide slide of the feed slide mechanism 2 are used to move the part to be ground on the workpiece adsorption platform 4, and the grinding machine 32 grinds it. The workpiece adsorption platform 4 can be a device commonly used in the art, such as a magnetic worktable of a grinding machine, a magnetic chuck platform of a surface grinder, an electromagnetic chuck, or an electrically controlled permanent magnet chuck. In this implementation plan, before grinding, please refer to... Figure 3 and Figure 4 As shown, the electric actuator 522 can also be activated, and the pressure head 523 on the output end of the electric actuator 522 is used to press against the surface of the part. With the design of multiple sets of electric actuators 522, the part to be ground can be fixed differently from the workpiece adsorption platform 4 mentioned above, and the part can be pressed at multiple points. Unlike relying on the bottom surface of the workpiece for single-sided adsorption and fixation, the pressure is evenly distributed to all parts of the part during the grinding operation, which can reduce damage to the part. At the same time, because the electric actuator 522 is set on the grinding path, the electric actuator 522 can further reduce the possibility of the part moving during the grinding operation, increase the stability of the part during the grinding process, and improve its grinding quality. It should also be noted that, depending on the actual operational needs, the equidistant design of the electric actuators 522 can be used instead of the above-mentioned design. The spacing between adjacent electric actuators 522 can also be adjusted as needed to provide a variety of clamping solutions. The output end of the electric actuator 522 is equipped with a pressure head 523, and the pressure head 523 has a built-in pressure sensing unit; the pressure sensing unit is used to uniformly set the output pressure of all electric actuators 522, so that each group of pressure heads 523 presses the parts with the same preset pressure. In this embodiment, the pressure sensing unit described above can be used to measure the clamping force of each electric actuator 522 output end on the part. The uniform clamping force design can balance the pressure at each part, which increases the stability of the part on the one hand, and avoids the movement or local damage caused by different clamping forces at different parts of the part on the other hand. In this embodiment, during the grinding process as the part moves along the workpiece adsorption platform 4, one of the electric push rods 522 gradually approaches the grinding tool on the grinding machine 32. When the preset clamping time or the preset position of the part is reached, the output end of the electric push rod 522 close to the grinding tool is controlled to release the clamping of the part, making it easier to grind. After grinding is completed, the output end of the electric push rod 522 clamps the part again with the same pressure, completing the operation of avoiding the grinding tool. In this way, the grinding part can be clamped without hindering the grinding operation, improving the stability of the part without affecting its grinding efficiency.

[0019] Example 2: A laser emitter 53 is installed on the inner wall of one side of the grinding chamber 1. The grinding chamber 1 is provided with a receiving surface for receiving the positioning beam on the side opposite to the laser emitter 53. A positioning block 57 is matched with an electric push rod 522 and is assembled at the output end of the electric push rod 522. When the part to be ground is pressed down synchronously with the same preset pressure, whether the positioning beam emitted by the laser emitter 53 can completely penetrate all the positioning blocks 57 and be projected onto the receiving surface of the grinding chamber 1 determines whether the part to be ground is in a stable clamping and fixed state. An ear seat 58 for connecting to the output end of the electric push rod 522 is fixed on one side of the positioning block 57. In this implementation scheme, during the implementation of the above embodiment one, the output end of the electric push rod 522 synchronously drives the positioning block 57 to move during operation. When the pressure head 523 presses the surface of the part, the positioning beam emitted by the laser emitter 53 can pass through all the positioning blocks 57 and be projected onto the receiving surface of the grinding chamber 1. This indicates that the part is stable in all places. If the positioning beam emitted by the laser emitter 53 does not pass through one of the positioning blocks 57, it indicates that while the same preset pressing force is achieved, the output displacement of the output end of one of the electric push rods 522 changes, causing its positioning beam to be projected onto the positioning block 57. This allows for a direct detection of which part of the part is in an unstable state, making it convenient for workers to check and adjust. This improves the grinding quality and facilitates adjustments by workers. It should also be noted that the size of the perforation on the aforementioned positioning block 57 can be adjusted by the operator according to the work situation.

[0020] Example 3: See Figure 5 As shown, the baffle 55 is fixed on the side of the main frame 510 and is distributed on both sides of the main frame 510 opposite to the electric push rod 522. When the baffle 55 moves with the electric push rod 522 to the sensing area of ​​the position sensing sensor 54, it outputs a signal. In the implementation of Embodiment 1, the following can be adopted: when one of the electric push rods 522 approaches the grinding tool, the baffle 55 on the opposite side of one of the electric push rods 522 moves into the sensing range of the position sensing sensor 54. At this time, the output end of the electric push rod 522 can be controlled to lift up to cancel the clamping of the part. Compared with Embodiment 1, where the preset clamping time or the preset position of the part is reached, the timing of the lifting of the electric push rod 522 in this embodiment is more precise. At the same time, the time from when the next baffle 55 moves into the position sensing sensor 54 to control the lifting of the electric push rod 522 can be recorded to detect whether the speed of the part movement is compliant, so as to avoid large fluctuations in the speed of the part movement, which would affect the grinding quality. Example 4: Furthermore, during practical operation, it was discovered that the part of the workpiece close to the grinding tool of the grinding machine 32 tends to move more due to the grinding operation than the part far away from the grinding tool. Therefore, to address this issue, during the grinding process, when one of the two electric push rods 522 adjacent to the grinding tool is about to approach the grinding tool, the baffle plate 55 moves into the sensing range of the position sensing sensor 54 and controls one of the corresponding electric push rods 522 to lift up, making it easier for the grinding tool to grind the workpiece. Meanwhile, the output end of the other electric push rod 522 increases the clamping force. This can increase the stability of the part close to the grinding tool and compensate for the reduced clamping force on the workpiece after one of the electric push rods 522 on either side of the grinding tool is lifted. Additionally, it should be noted that the output end of the other electric actuator 522 mentioned above is increased with clamping force, and the range of increase in clamping force can be increased by those skilled in the art as appropriate; at the same time, the time of the increased clamping force can also be set by those skilled in the art as appropriate. Furthermore, when the above findings are not required in the operation, the clamping force of the electric actuator 522 can be left unadjusted without affecting the implementation of the other embodiments mentioned above. Additionally, it should be noted that when the above technical solution is used in combination with the technical solution of Embodiment 2, after the output end of the electric push rod 522 is increased with clamping force, the positioning beam emitted by the laser emitter 53 can still pass through the positioning block 57. Depending on the operation or part specifications, they may not be used in combination, which will not affect the implementation of other embodiments or the combined implementation.

[0021] Example 5: See Figures 5 to 9 As shown, piston component 560 is fixed to the bottom of main frame 510 and located between electric actuator 522 and main frame 510. The bottom of piston component 560 is connected to sleeve 563 via delivery hose 562. Sleeve 563 is sleeved on the output end of electric actuator 522. Piston component 560 is divided into piston cylinder and piston rod. The piston rod is connected to the output end of electric actuator 522 via connecting rod 561. The bottom of sleeve 563 is provided with nozzle 564 surrounding the outside of pressure head 523. In the implementation of Embodiment 1, when the output end of the electric actuator 522 operates, it simultaneously drives the connecting rod 561 to move. The connecting rod 561 drives the piston rod to move inside the piston cylinder to extract or discharge gas. Since the piston component 560 is connected to the sleeve 563 through the delivery hose 562, and since the nozzle 564 on the sleeve 563 surrounds the outside of the pressure head 523, when the electric actuator 522 drives the pressure head 523 to lift and cancel contact with the part, the stored gas is extracted into the piston component 560. When the electric actuator 522 drives the pressure head 523 to move and contact and press with the part, the gas extracted and stored inside the piston component 560 is discharged through the nozzle 564 on the sleeve 563. During the process of the pressure head 523 moving and contacting and pressing with the part, the cutting fluid or impurities directly below the pressure head 523 can be blown away and exposed to the surface of the part, or impurities can be blown away, so that the pressing surface between the pressure head 523 and the part is kept clean, so as to prevent impurities from being squeezed and damaged by the pressure head 523. At the same time, it can avoid the influence of impurities in the above embodiment. It should also be noted that the gas in the above technical solution can be replaced with other media commonly used by those skilled in the art, such as inert gas. If the inert gas can not only disperse cutting fluid and impurities, but also pretreat the surface of the part, the above gas can be replaced with inert gas. Additionally, to ensure the accurate implementation of the above embodiments, the nozzle 564 can be a pressurized nozzle to increase the outlet pressure, or a small air blowing device can be installed on one side of the baffle plate 55, with the outlet end also connected to the delivery hose 562, thereby ensuring that the outlet pressure can disperse the cutting fluid or impurities. Those skilled in the art can use the above-mentioned piston component 560 and its components to implement the technical means, depending on the operating conditions, which is more economical. Alternatively, a small air blowing device can be used to replace the piston component 560 and its components.

[0022] It should also be noted that the present invention comprises five sets that can be implemented independently or combined arbitrarily for grinding operations.

[0023] Working principle: After the equipment is powered on, the electrical control system automatically performs parameter initialization, reads the preset standard pressure on the human-machine interface, and completes zero-point calibration of the built-in pressure sensors of each pressure head 523. It also synchronously verifies the electric push rod 522, the position sensing sensor 54 communication line. In case of hardware failure, the equipment is locked and an alarm prompt pops up. After the parts to be ground are placed on the workpiece adsorption platform 4, the operator starts the automatic processing program. The PLC synchronously outputs drive signals to all electric push rods 522, driving the pressure head 523 to feed and adhere to the surface of the parts. Each pressure sensor on the pressure head 523 collects pressure data in real time and uploads it to the PLC. The electrical control system compares the collected pressure with the preset standard pressure in real time until the pressure difference at all points is controlled within the allowable error range, thus completing the multi-point clamping of the parts. If the pressure at any point exceeds the safety threshold, the system immediately raises the corresponding pressure head 523 and stops the machine with an alarm. After the pressure head 523 presses the part, the PLC starts the laser emitter 53 to output a positioning beam. After the positioning beam penetrates all the positioning blocks 57, it is determined that the part is not offset and is stable. The workpiece adsorption platform 4 is driven to feed and drive the main frame 510 to feed and grind synchronously. If the positioning beam is blocked by the positioning block 57, the equipment is locked and waits for manual reset. During the grinding feed, the optical path obstruction signal is continuously monitored. When the position sensor 54 of the obstruction plate 55 moves within the sensing range, the output signal is recognized by the PLC, which then controls the pressure head 523 of that station to rise to avoid the grinding tool. At the same time, the pressure of the pressure head 523 of the adjacent station is automatically increased for compensation. After the obstruction plate 55 leaves the sensing range of the position sensor 54, the pressure head 523 is pressed down to reset, the pressure increase compensation of the adjacent pressure head 523 is canceled, and the standard pressure equalization state is restored. During the downward or upward movement of the pressure head 523 to avoid collision, the nozzle 564 sprays gas to disperse the cutting fluid and impurities on the contact surface. After the parts are ground, the main frame 510 returns to the loading and unloading station, and all electric actuators 522 are raised synchronously, thus ending the processing flow.

[0024] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
