Description

Technical Field

[0001] This application relates to the field of machine tool technology, and in particular to a horizontal surface grinder. Background Technology

[0002] A grinding machine is a type of machine tool that uses abrasives to grind the surface of a workpiece. Grinding is one of the main methods for precision machining of machine parts. The principle of grinding is to grind the surface of a workpiece by means of relative friction between a high-speed rotating grinding wheel and the workpiece surface. Specifically, the workpiece on the reciprocating sliding machining table continuously contacts and grinds the workpiece with the high-speed rotating grinding wheel.

[0003] Grinding wheels also wear down during the grinding process. Although the amount of wear is small, for some workpieces with high requirements for surface flatness, the continuous wear of the grinding wheel during processing can easily lead to a lower surface flatness and defects in the final workpiece. Summary of the Invention

[0004] In order to improve the flatness of the workpiece surface, this application provides a horizontal surface grinder.

[0005] The horizontal surface grinder provided in this application adopts the following technical solution: A horizontal surface grinder includes a frame with a horizontally slidable placement groove. A transverse traverse member is mounted on the frame to drive the placement groove to slide. A processing table for placing a workpiece is mounted on the placement groove. A vertically slidable lifting arm is mounted on the frame, and a lifting member is mounted on the frame to drive the lifting arm to slide. A horizontally longitudinally slidable mounting plate is mounted on the lifting arm, and a longitudinal traverse member is mounted on the lifting arm to drive the mounting plate to slide. A hollow, open-bottomed protective shell is vertically slidable on the mounting plate, and the protective shell is provided with... The device includes a nozzle and a grinding motor, the grinding motor being electrically connected to a control system. A grinding wheel is rotatably mounted inside the protective housing. The liquid outlet of the nozzle points towards the contact position between the grinding wheel and the workpiece. The grinding wheel is detachably mounted on the output shaft of the grinding motor. A laser rangefinder and a distance control assembly are mounted on the mounting plate. The laser rangefinder is electrically connected to the control system and is located on both sides of the grinding wheel's grinding direction. The laser rangefinder is used to measure the distance between the mounting plate and the workpiece surface. The distance control assembly is used to dynamically control the distance between the protective housing and the workpiece.

[0006] By adopting the above technical solution, the worker first fixes the workpiece on the processing table. Then, the longitudinal traverse component drives the mounting plate to slide, thereby moving the grinding wheel above the workpiece. Afterward, the lifting component drives the lifting arm to descend and approach the workpiece on the processing table. At this time, the output shaft of the grinding motor drives the grinding wheel to rotate at high speed until the rotating grinding wheel touches the workpiece. The laser rangefinder feeds back the measured distance to the control system. At the same time, the transverse traverse component drives the placement slot to slide. The placement slot carries the workpiece through the processing table. During the sliding process, the workpiece is ground by the grinding wheel, and the nozzle sprays coolant onto the grinding position of the workpiece. During this process, the laser rangefinder feeds back the distance values ​​measured on both sides of the grinding direction of the grinding wheel to the control system. The distance control component fine-tunes the distance between the protective shell and the workpiece based on the information fed back by the two laser rangefinders, so that the grinding wheel gets closer to the workpiece during the grinding process, thereby improving the processing accuracy of the workpiece's surface flatness.

[0007] Optionally, the distance control assembly includes a fine-tuning cylinder mounted on the mounting plate, a protective shell mounted on the piston rod of the fine-tuning cylinder, a guide cylinder mounted on the mounting plate, a guide rod mounted on the protective shell, the axis of the guide rod being parallel to the axis of the piston rod of the fine-tuning cylinder, the guide cylinder being coaxially slidably sleeved on the guide rod, and an anti-misoperation component mounted on the protective shell, the anti-misoperation component being used to reduce the influence of the coolant sprayed from the nozzle on the distance measurement of the laser rangefinder.

[0008] Optionally, the anti-misoperation component includes support plates disposed on the protective shell and on both sides along the sliding direction of the placement groove. Two laser rangefinders are disposed on the mounting plate, with each laser rangefinder corresponding to one of the support plates. An elastic bellows is disposed on the support plate, with one end of the elastic bellows facing away from the support plate used to abut against the surface of the workpiece. Both ends of the elastic bellows are fitted with ring plates. A guide post is disposed on the ring plate near the workpiece end. The guide post slides sequentially through the ring plate and the support plate located above. An anti-detachment block is disposed on the guide post on the side of the support plate facing away from the ring plate. A compression spring supports the two ring plates. The laser emitted by the laser rangefinder is located inside the elastic bellows.

[0009] By adopting the above technical solution, under the elastic force of the compression spring, the bottom of the elastic bellows will abut against the surface of the workpiece. During the sliding process of the placement groove, the elastic bellows will always isolate the coolant sprayed from the nozzle. At this time, the laser emitted by the laser rangefinder will directly irradiate the surface of the workpiece. The information fed back by the two laser rangefinders will promptly feed back the surface condition of the workpiece to the control system. The control system will then activate the fine-tuning cylinder. The piston rod of the fine-tuning cylinder will automatically extend, thereby bringing the grinding wheel closer to the surface of the workpiece, thus polishing the surface of the workpiece and achieving the effect of improving the surface flatness of the workpiece.

[0010] Optionally, the elastic bellows has an inclined anti-collision guide plate on the ring plate near the workpiece end. The anti-collision guide plate is inclined away from the protective shell in a downward direction, and the inclined surface of the anti-collision guide plate is used to abut against the edge of the workpiece side.

[0011] By adopting the above technical solution, during the repeated sliding of the workpiece, the elastic bellows on the side of the protective shell facing the sliding direction of the workpiece will gradually separate from the workpiece surface until the grinding wheel grinds to the edge of the workpiece. At this time, the workpiece will move in the opposite direction, and the anti-collision guide plate will hit the edge of the workpiece. Under the guidance of the anti-collision guide plate, the compression spring is compressed until the bottom of the elastic bellows slides in again and abuts against the surface of the workpiece. During the process of the bottom of the elastic bellows sliding into the surface of the workpiece, it will scrape off the coolant on the surface of the workpiece, thereby reducing the amount of coolant entering the interior of the elastic bellows and affecting the measurement accuracy of the laser rangefinder.

[0012] Optionally, the transverse component includes a transverse slide rail disposed on the frame, the placement slot is slidably disposed on the transverse slide rail, a transverse lead screw is rotatably disposed on the frame, a transverse block is threadedly connected to the transverse lead screw, the transverse block is disposed on the placement slot, a transverse motor electrically connected to the control system is disposed on the frame, and the transverse lead screw is coaxially disposed on the output shaft of the transverse motor.

[0013] Optionally, the lifting component includes a linear module mounted on the frame, and the lifting arm is mounted on the slider of the linear module.

[0014] Optionally, the longitudinal movement component includes a longitudinal movement slide rail disposed on the lifting arm, a mounting plate slidably disposed on the longitudinal movement slide rail, a longitudinal movement screw rotatably disposed on the lifting arm, a longitudinal movement block threadedly connected to the longitudinal movement screw, the longitudinal movement block disposed on the mounting plate, a longitudinal movement motor electrically connected to the control system disposed on the lifting arm, and the longitudinal movement screw coaxially disposed on the output shaft of the longitudinal movement motor.

[0015] By adopting the above technical solution, the grinding wheel can grind any position on the top surface of the workpiece, thereby achieving the effect of improving the accuracy of the workpiece surface flatness.

[0016] Optionally, the protective shell is provided with a splash guard, the grinding motor is located in the splash guard, and the top of the splash guard is provided with heat dissipation holes.

[0017] By adopting the above technical solution, the possibility of damage to the grinding motor caused by coolant splashing is reduced.

[0018] In summary, this application includes at least one of the following beneficial technical effects: The worker first fixes the workpiece on the processing table. Then, the longitudinal traverse component drives the mounting plate to slide, thereby moving the grinding wheel above the workpiece. After that, the lifting component drives the lifting arm to descend and approach the workpiece on the processing table. At this time, the output shaft of the grinding motor drives the grinding wheel to rotate at high speed until the rotating grinding wheel touches the workpiece. The laser rangefinder feeds back the measured distance to the control system. At the same time, the transverse traverse component drives the placement slot to slide. The placement slot carries the workpiece through the processing table. During the sliding process, the workpiece is ground by the grinding wheel, and the nozzle sprays coolant onto the grinding position of the workpiece. During this process, the laser rangefinder feeds back the distance values ​​measured on both sides of the grinding direction of the grinding wheel to the control system. The distance control component fine-tunes the distance between the protective shell and the workpiece based on the information fed back by the two laser rangefinders, so that the grinding wheel gets closer to the workpiece during the grinding process, thereby improving the processing accuracy of the workpiece's surface flatness. Under the elastic force of the compression spring, the bottom of the elastic bellows will abut against the surface of the workpiece. During the sliding process of the placement groove, the elastic bellows will always isolate the coolant sprayed from the nozzle. At this time, the laser emitted by the laser rangefinder will directly irradiate the surface of the workpiece. The information fed back by the two laser rangefinders will promptly feed back the surface condition of the workpiece to the control system. The control system will then activate the fine-tuning cylinder. The piston rod of the fine-tuning cylinder will automatically extend, thereby bringing the grinding wheel closer to the surface of the workpiece, thus polishing the surface of the workpiece and improving the surface smoothness of the workpiece. During the repeated sliding of the workpiece, the elastic bellows on the side of the protective shell facing the sliding direction of the workpiece will gradually separate from the workpiece surface until the grinding wheel grinds to the edge of the workpiece. At this time, the workpiece will move in the opposite direction, and the anti-collision guide plate will hit the edge of the workpiece. Under the guidance of the anti-collision guide plate, the compression spring is compressed until the bottom of the elastic bellows slides in again and abuts against the surface of the workpiece. During the process of the bottom of the elastic bellows sliding into the surface of the workpiece, it will scrape off the coolant on the surface of the workpiece, thereby reducing the amount of coolant entering the interior of the elastic bellows and affecting the measurement accuracy of the laser rangefinder.

The linear module 7 can be a ball screw type linear module 7 in the prior art.

[0029] Reference Figure 1 , Figure 2 and Figure 3A mounting plate 8 is horizontally and longitudinally slidably arranged on the lifting arm 6. A longitudinal moving member 9 is arranged on the lifting arm 6 to drive the mounting plate 8 to slide. The longitudinal moving member 9 includes a longitudinal moving slide rail 91 bolted to the lifting arm 6. The mounting plate 8 is slidably connected to the longitudinal moving slide rail 91.

[0030] Reference Figure 2 and Figure 3 A longitudinal lead screw 92 is rotatably connected to the lifting arm 6. A longitudinal block 93 is threaded onto the longitudinal lead screw 92. The longitudinal block 93 is bolted to the mounting plate 8. A longitudinal motor 94, which is electrically connected to the control system, is bolted onto the lifting arm 6. The longitudinal motor 94 can be a forward and reverse motor as in the prior art. The longitudinal lead screw 92 is coaxially bolted to the output shaft of the longitudinal motor 94.

[0031] Reference Figure 1 and Figure 3 A hollow protective shell 10 with an open bottom is vertically slidably arranged on the mounting plate 8. A nozzle 11 and a grinding motor 12 are bolted to the protective shell 10. The nozzle 11 is connected to the liquid supply system (not shown in the figure) through a hose. The grinding motor 12 is electrically connected to the control system. A splash shield 18 is bolted to the protective shell 10. The grinding motor 12 is located in the splash shield 18. A heat dissipation hole 19 is provided on the top of the splash shield 18.

[0032] Reference Figure 2 and Figure 3 Inside the protective shell 10, a grinding wheel 13 is rotatably connected. The liquid outlet end of the nozzle 11 points to the contact position between the grinding wheel 13 and the workpiece 1. The grinding wheel 13 is bolted to the output shaft of the grinding motor 12. A laser rangefinder 14, which is electrically connected to the control system, is bolted to the mounting plate 8. The laser rangefinder 14 is located on both sides of the grinding direction of the grinding wheel 13. The laser rangefinder 14 is used to measure the distance between the mounting plate 8 and the surface of the workpiece 1.

[0033] The worker first fixes the tool on the processing table 5 using a clamp, and then starts the longitudinal transfer motor 94 through the control system. The output shaft of the longitudinal transfer motor 94 drives the longitudinal transfer screw 92 to rotate. Under the guidance of the longitudinal transfer slide rail 91, the mounting plate 8 slides along the axis of the longitudinal transfer screw 92, thereby causing the mounting plate 8 to move the grinding wheel 13 to directly above the workpiece 1.

[0034] At this time, the output shaft of the grinding motor 12 drives the grinding wheel 13 to rotate at high speed, while the laser rangefinder 14 measures the distance between the mounting plate 8 and the surface of the workpiece 1 and feeds it back to the control system. Then, the control system controls the slider of the linear module 7 to drive the lifting arm 6 to descend until the rotating grinding wheel 13 comes into contact with the surface of the workpiece 1. At this time, the liquid supply system will spray coolant at the contact position between the grinding wheel 13 and the workpiece 1 through the nozzle 11.

[0035] Finally, the output shaft of the transverse motor 44 drives the transverse lead screw 42 to rotate. Through the forward and reverse rotation of the output shaft of the transverse motor 44, the placement groove 3 slides repeatedly. During this process, the surface of the workpiece 1 is continuously polished.

[0036] Reference Figure 2 and Figure 4 A distance control component 15 is arranged on the mounting plate 8. The distance control component 15 is used to dynamically control the distance between the protective shell 10 and the workpiece 1.

[0037] Reference Figure 2 and Figure 4 The distance control assembly 15 includes a fine-tuning cylinder 151 bolted to the mounting plate 8, a protective shell 10 bolted to the piston rod of the fine-tuning cylinder 151, a guide cylinder 152 bolted to the mounting plate 8, and a guide rod 153 bolted to the protective shell 10. The axis of the guide rod 153 is parallel to the axis of the piston rod of the fine-tuning cylinder 151, and the guide cylinder 152 is coaxially slidably sleeved on the guide rod 153.

[0038] Reference Figure 2 and Figure 4 The protective housing 10 is provided with an anti-misoperation component 16, which is used to reduce the influence of the coolant sprayed from the nozzle 11 on the ranging of the laser rangefinder 14.

[0039] Reference Figure 2 and Figure 4 The anti-misoperation component 16 includes support plates 161 welded to the protective shell 10 and sliding on both sides of the placement groove 3. Two laser rangefinders 14 are installed on the mounting plate 8, and the laser rangefinders 14 correspond one-to-one with the support plates 161. An elastic corrugated tube 162 is bonded to the support plate 161. The elastic corrugated tube 162 can be made of flexible rubber material. The end of the elastic corrugated tube 162 facing away from the support plate 161 is used to abut against the surface of the workpiece 1.

[0040] Reference Figure 2 and Figure 4 Both ends of the elastic bellows 162 are fitted with ring plates 163. A guide post 164 is welded to the ring plate 163 near the workpiece 1. The guide post 164 slides through the ring plate 163 and the support plate 161 located above in sequence. An anti-detachment block 165 is bolted to the guide post 164 on the side of the support plate 161 facing away from the ring plate 163. A compression spring 166 is supported between the two ring plates 163. The compression spring 166 is fitted on the guide post 164. The laser emitted by the laser rangefinder 14 is located inside the elastic bellows 162.

[0041] Reference Figure 2 and Figure 4An inclined anti-collision guide plate 17 is welded to the ring plate 163 near one end of the elastic bellows 162, which is close to the workpiece 1. The anti-collision guide plate 17 is inclined away from the protective shell 10 in a downward direction, and the inclined surface of the anti-collision guide plate 17 is used to abut against the edge of the side of the workpiece 1.

[0042] During the processing of workpiece 1, under the elastic force of spring 166, the bottom of elastic bellows 162 will abut against the surface of workpiece 1. During the sliding of placement groove 3, elastic bellows 162 will always isolate the coolant sprayed from nozzle 11. At this time, the laser emitted by laser rangefinder 14 will directly irradiate the surface of workpiece 1. The two laser rangefinders 14 will feed back the surface condition of workpiece 1 in the grinding direction of grinding wheel 13 to the control system.

[0043] Based on the feedback from the workpiece 1 surface after grinding and the feedback from before grinding, the control system will activate the fine-tuning cylinder 151. The piston rod of the fine-tuning cylinder 151 will automatically extend a certain distance, thereby continuously changing the magnitude of the clamping force of the grinding wheel 13 on the workpiece 1, so that the surface flatness of the workpiece 1 tends to be uniform, and ultimately achieving the effect of improving the precision of the surface flatness of the workpiece 1.

[0044] During the repeated sliding of workpiece 1, the elastic bellows 162 on the side of the protective shell 10 facing the sliding direction of workpiece 1 will gradually separate from the surface of workpiece 1 until the grinding wheel 13 grinds to the edge of workpiece 1. At this time, workpiece 1 will move in the opposite direction, and the anti-collision guide plate 17 will hit the edge of workpiece 1.

[0045] Under the guidance of the anti-collision guide plate 17, the compression spring 166 is compressed, and the bottom of the elastic bellows 162 will slide in again and abut against the surface of the workpiece 1. During the process of sliding into the surface of the workpiece 1, the bottom of the elastic bellows 162 will scrape away the coolant on the surface of the workpiece 1, thereby reducing the amount of coolant entering the elastic bellows 162 and affecting the measurement accuracy of the laser rangefinder 14.

[0046] The implementation principle of a horizontal surface grinder according to an embodiment of this application is as follows: the worker first fixes the tool on the processing table 5 with a fixture, and then starts the longitudinal traverse motor 94 through the control system. The output shaft of the longitudinal traverse motor 94 drives the longitudinal traverse screw 92 to rotate. Under the guidance of the longitudinal traverse slide rail 91, the mounting plate 8 slides along the axial direction of the longitudinal traverse screw 92, thereby causing the mounting plate 8 to drive the grinding wheel 13 to move directly above the workpiece 1.

[0047] At this time, the output shaft of the grinding motor 12 drives the grinding wheel 13 to rotate at high speed, while the laser rangefinder 14 measures the distance between the mounting plate 8 and the surface of the workpiece 1 and feeds it back to the control system. Then, the control system controls the slider of the linear module 7 to drive the lifting arm 6 to descend until the rotating grinding wheel 13 comes into contact with the surface of the workpiece 1. At this time, the liquid supply system will spray coolant at the contact position between the grinding wheel 13 and the workpiece 1 through the nozzle 11.

[0048] Finally, the output shaft of the transverse motor 44 drives the transverse lead screw 42 to rotate. Through the forward and reverse rotation of the output shaft of the transverse motor 44, the placement groove 3 slides repeatedly. During this process, the surface of the workpiece 1 is continuously polished.

[0049] During the processing of workpiece 1, under the elastic force of spring 166, the bottom of elastic bellows 162 will abut against the surface of workpiece 1. During the sliding of placement groove 3, elastic bellows 162 will always isolate the coolant sprayed from nozzle 11. At this time, the laser emitted by laser rangefinder 14 will directly irradiate the surface of workpiece 1. The two laser rangefinders 14 will feed back the surface condition of workpiece 1 in the grinding direction of grinding wheel 13 to the control system.

[0050] Based on the feedback from the workpiece 1 surface after grinding and the feedback from before grinding, the control system will activate the fine-tuning cylinder 151. The piston rod of the fine-tuning cylinder 151 will automatically extend a certain distance, thereby continuously changing the magnitude of the clamping force of the grinding wheel 13 on the workpiece 1, so that the surface flatness of the workpiece 1 tends to be uniform, and ultimately achieving the effect of improving the precision of the surface flatness of the workpiece 1.

[0051] During the repeated sliding of workpiece 1, the elastic bellows 162 on the side of the protective shell 10 facing the sliding direction of workpiece 1 will gradually separate from the surface of workpiece 1 until the grinding wheel 13 grinds to the edge of workpiece 1. At this time, workpiece 1 will move in the opposite direction, and the anti-collision guide plate 17 will hit the edge of workpiece 1.

[0052] Under the guidance of the anti-collision guide plate 17, the compression spring 166 is compressed, and the bottom of the elastic bellows 162 will slide in again and abut against the surface of the workpiece 1. During the process of sliding into the surface of the workpiece 1, the bottom of the elastic bellows 162 will scrape away the coolant on the surface of the workpiece 1, thereby reducing the amount of coolant entering the elastic bellows 162 and affecting the measurement accuracy of the laser rangefinder 14.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
