Description

Technical Field

[0001] This invention relates to the field of centerless grinding equipment technology, and in particular to a linear bearing bushing external cylindrical grinding equipment and its working method. Background Technology

[0002] like Figure 1 The linear bearing bushing 7 shown has an external thread 7a at the center of its outer circumference. When grinding the outer diameter of the linear bearing bushing with a centerless grinder, in order to prevent the grinding wheel from grinding the external thread on the outer side of the linear bearing bushing, the prior art usually has a flange threadedly fixed to the external thread, and clearance grooves are provided on the grinding wheel, guide wheel, and support plate. During grinding, the linear bearing bushing is placed on the support plate between the grinding wheel and the guide wheel, with the flange located in the clearance groove. Then, the axial feed force of the centerless grinder on the linear bearing bushing during grinding causes the flange to abut against the side of the clearance groove on the support plate. Although this method can achieve the grinding of the outer diameter of the linear bearing bushing, it is relatively troublesome to install and remove the flange, resulting in low processing efficiency. Moreover, if the flange is not perpendicular to the axis of the linear bearing bushing during installation, it will cause errors in the grinding of the outer diameter of the linear bearing bushing.

[0003] Therefore, in order to address this problem, the present invention provides a linear bearing bushing outer cylindrical grinding device. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of low grinding efficiency of the outer diameter of linear bearing bushings due to the need to install and disassemble flanges in the prior art, and to propose a grinding equipment for the outer diameter of linear bearing bushings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A linear bearing bushing external cylindrical grinding device includes a frame. A grinding wheel is rotatably connected to the upper left side of the top plate of the frame, and a guide wheel is oscillatingly connected to the upper right side. A support plate is provided between the grinding wheel and the guide wheel at the upper end of the top plate of the frame. A clearance ring groove is provided on the outer circumference of the grinding wheel and the guide wheel. A clearance slot is provided at the upper end of the support plate. A stop block is provided at the rear side of the clearance slot at the upper end of the support plate. When the linear bearing bushing is placed on the upper end of the support plate and the rear end of the linear bearing bushing abuts against the stop block, the external thread on the outer side of the linear bearing bushing is in the clearance slot and the clearance ring groove. During the grinding of the linear bearing bushing, the rear end of the linear bearing bushing abuts against the stop block.

[0007] Furthermore, the top left side of the frame's top plate is provided with two left convex plates, and the grinding wheel is rotatably connected between the upper ends of the two left convex plates. A first motor for driving the grinding wheel to rotate is fixedly mounted on one of the left convex plates. The top right side of the frame's top plate is provided with a rear convex plate, and the upper end of the rear convex plate is rotatably connected to an upper shaft rod arranged in the front-rear direction. Two connecting plates arranged side by side are fixedly mounted on the upper shaft rod, and a lower shaft rod parallel to the upper shaft rod is rotatably connected between the two connecting plates. The guide wheel is fixedly mounted on the lower shaft rod. A second motor for driving the upper shaft rod to rotate is fixedly mounted on the rear convex plate. When the upper shaft rod rotates, it drives the guide wheel to swing through the connecting plates. A third motor for driving the lower shaft rod to rotate is fixedly mounted on the connecting plate away from the rear convex plate.

[0008] Furthermore, the frame includes a horizontal plate located below the top plate, and a channel with a left-opening, square cross-section is formed between the top plate and the plate. A feeding slider is slidably connected within the channel in the left-right direction. The top plate of the frame has a feed inlet below the guide wheel, and a guide block is fixed to the right side of the push plate on the top plate. The guide block has an arc-shaped inclined surface with the swing center of the guide wheel as its axis, and the lower end of the arc-shaped inclined surface extends to the left side of the feed inlet. After the outer circle of the linear bearing bush is machined, as the guide wheel swings counterclockwise, the linear bearing bush moves downward along the arc-shaped inclined surface under its own weight and enters the feed inlet.

[0009] Furthermore, an end plate is fixedly provided at the left end of the channel, and a tension spring is fixedly provided between the left end of the feeding slider and the end plate. The tension spring is used to force the feeding slider to move to the left. A vertical protrusion extending upward from the feed inlet is fixedly provided at the right end of the feeding slider. When the guide wheel swings counterclockwise, the guide wheel moves the vertical protrusion, causing the feeding slider to move to the right. When the guide wheel swings counterclockwise to the lowest position, the vertical protrusion abuts against the right end of the feed inlet. When the guide wheel swings clockwise, the feeding slider moves to the left under the action of the tension spring. When the guide wheel swings clockwise to the lowest position, the vertical protrusion abuts against the right end of the feed inlet. When in the working position, the vertical convex plate abuts against the left end of the feed inlet; the feed slider has a groove with an opening at the top, and a protrusion is provided in the groove near the right end. An oil groove is formed on the left side of the protrusion in the groove, and cooling oil is provided in the oil groove. The left end of the protrusion has an inclined surface extending from the top of the protrusion to the bottom of the groove. The protrusion has a vertical slot near the right end, and the bottom of the groove has a connecting groove that communicates with the lower end of the vertical slot. The plate has a feed port that runs through the top and bottom; the inner side of the top plate has a pushing component.

[0010] Furthermore, when the feeding slider moves to the left, the linear bearing bushing pushed by the pushing component into the oil groove passes through the inclined surface and the top surface of the protrusion and enters the vertical slot and falls into the connecting groove. Since the connecting groove is offset from the feeding port, the linear bearing bushing is located on the plate at this time. When the feeding slider moves to the right, the feeding slider drives the linear bearing bushing in the connecting groove to move to the right. When the vertical protrusion moves to the right end of the feeding port, the linear bearing bushing enters the feeding port and is sent out.

[0011] Furthermore, the pushing component includes a pushing filter plate. Two vertically downward extending guide rods are fixedly provided on the lower end face of the top plate. The pushing filter plate is slidably connected between the lower ends of the two guide rods in the vertical direction. Under the action of gravity, the lower end of the pushing filter plate abuts against the bottom of the groove, the inclined surface, or the top surface of the protrusion. The lower end of the pushing filter plate is provided with a guide slope. When the feeding slider moves to the left, the guide slope abuts against the inclined surface. As the feeding slider continues to move to the left, the guide slope and the inclined surface cooperate to push the filter plate upward.

[0012] Furthermore, the plate has an oil filter groove with an upper opening on the left side of the feed inlet. The bottom of the oil filter groove is threaded with a screw plug. An oil filter plate is fixedly installed at the upper opening of the oil filter groove. The upper surface of the oil filter plate is 1 mm lower than the upper surface of the plate. When the vertical convex plate abuts against the left end of the feed inlet, the linear bearing bushing entering the connecting groove is positioned on the oil filter plate.

[0013] Furthermore, the guide block is provided with an arc-shaped clearance opening on the arc-shaped inclined surface.

[0014] The present invention also provides a method for operating the above-mentioned linear bearing bushing external cylindrical grinding equipment, comprising the following steps:

[0015] S1. Control the guide wheel to swing clockwise to the processing position, place the linear bearing bushing to be processed on the support plate, and ensure that the external thread of the linear bearing bushing is located in the clearance groove and clearance ring groove, and the rear end face of the linear bearing bushing abuts against the protrusion.

[0016] S2. Start the guide wheel and grinding wheel to grind the outer diameter of the linear bearing bushing; after the grinding time is set, the linear bearing bushing is finished, and control the guide wheel and grinding wheel to stop rotating;

[0017] S3. Control the guide wheel to swing counterclockwise. The processed linear bearing bushing moves downward along the arc-shaped inclined plane under its own gravity. At the same time, the guide wheel drives the unloading slider to move to the right through the vertical convex plate. When the vertical convex plate moves to the right end of the feed port, the processed linear bearing bushing enters the oil tank through the feed port and is cooled by the cooling oil.

[0018] S4. Control the guide wheel to swing clockwise towards the processing position. The unloading slider moves to the left under the action of the tension spring. The pushing component pushes the processed linear bearing bushing in the oil groove to the top surface of the protrusion. When the vertical protrusion moves to the left end of the feeding port, the pushing component pushes the processed linear bearing bushing into the vertical slot and falls into the connecting slot. At this time, the processed linear bearing bushing is on the oil filter plate.

[0019] S5. Repeat S1 to S3. When the vertical convex plate moves to the right end of the feed port, the unloading slider drives the finished linear bearing bush above the oil filter plate to move to the right through the connecting groove and is sent out from the unloading port. At this time, the newly finished linear bearing bush enters the oil tank from the feed port.

[0020] Compared with the prior art, the present invention provides a linear bearing bushing outer cylindrical grinding device, which has the following beneficial effects:

[0021] 1. This grinding equipment, by using vertical protrusions on the support plate, ensures that the rear end of the linear bearing bushing abuts against the stop block during external cylindrical grinding, eliminating the need to install or disassemble the flange and greatly improving grinding efficiency.

[0022] 2. This grinding equipment, by setting a feeding slide that cooperates with the guide wheel and a pushing component that cooperates with the feeding slide, can realize the automatic feeding, cooling and delivery of the processed linear bearing bush as the guide wheel swings, which greatly improves processing efficiency and saves labor costs.

[0023] 3. By setting up an oil filter plate and an oil filter groove, when the next linear bearing bush is processed within a set time, the cooling oil adhering to the processed linear bearing bush in the connecting groove enters the oil filter groove through the oil filter plate, greatly reducing the amount of cooling oil adhering to the processed linear bearing bush; after a certain amount of cooling oil has accumulated in the oil filter groove, the screw plug can be opened to release the cooling oil in the oil filter groove.

[0036] Reference Figures 2-10A linear bearing bushing external cylindrical grinding device includes a frame 1. A grinding wheel 2 is rotatably connected to the upper left side of the top plate 1a of the frame 1, and a guide wheel 3 is oscillatingly connected to the upper right side of the top plate 1a. A support plate 4 is provided between the grinding wheel 2 and the guide wheel 3 at the upper end of the top plate 1a of the frame 1. A clearance ring groove 32 is provided on the outer circumference of the grinding wheel 2 and the guide wheel 3. A clearance slot 4a is provided at the upper end of the support plate 4. A stop block 4b is provided on the rear side of the clearance slot 4a at the upper end of the support plate 4. When the linear bearing bushing 7 is placed at the upper end of the support plate 4 and the rear end of the linear bearing bushing 7 abuts against the stop block 4b, the external thread 7a on the outer side of the linear bearing bushing 7 is in the clearance slot 4a and the clearance ring groove 32. When the linear bearing bushing 7 is ground, the rear end of the linear bearing bushing 7 abuts against the stop block 4b. In this embodiment, two left convex plates 1b are provided on the upper left side of the top plate 1a of the frame 1. The grinding wheel 2 is rotatably connected between the upper ends of the two left convex plates 1b. A first motor 5 for driving the grinding wheel 2 to rotate is fixed on one of the left convex plates 1b. A rear convex plate 1c is provided on the upper right side of the top plate 1a of the frame 1. An upper shaft 6 arranged in the front-rear direction is rotatably connected to the upper end of the rear convex plate 1c. Two connecting plates 8 arranged side by side are fixed on the upper shaft 6. A lower shaft 9 parallel to the upper shaft 6 is rotatably connected between the two connecting plates 8. The guide wheel 3 is fixedly installed on the lower shaft 9. A second motor 10 for driving the upper shaft 6 to rotate is fixed on the rear convex plate 1c. When the upper shaft 6 rotates, it drives the guide wheel 3 to swing through the connecting plates 8. A third motor 11 for driving the lower shaft 9 to rotate is fixed on the connecting plate 8 away from the rear convex plate 1c.

[0037] The frame 1 has a horizontal plate 1d located below the top plate 1a. A channel 101 with a left-open, square cross-section is formed between the top plate 1a and the plate 1d. A feeding slider 12 is slidably connected within the channel 101 in a left-right direction. A feed inlet 1a1 is located below the guide wheel 3 within the top plate 1a of the frame 1. A guide block 13 is fixedly mounted on the right side of the push plate on the top plate 1a of the frame 1. The guide block 13 is equipped with a mechanism that swings with the guide wheel 3. An arc-shaped inclined surface 13a with its axis of motion extends from its lower end to the left side of the feed inlet 1a1. The guide block 13 has an arc-shaped clearance opening 13b on the arc-shaped inclined surface 13a. This clearance opening 13b serves two purposes: firstly, it avoids the external thread 7a on the outer side of the linear bearing bush 7; secondly, the sides of the arc-shaped clearance opening 13b engage with the ends of the external thread 7a to ensure that the linear bearing bush 7 can enter the feed inlet 1a1 along the arc-shaped inclined surface 13a. After the outer diameter of the linear bearing bush 7 is machined, as the guide wheel 3 swings counterclockwise, the linear bearing bush 7 moves downwards along the arc-shaped inclined surface 13a under its own weight and enters the feed inlet 1a1.

[0038] In this embodiment, an end plate 14 is fixedly provided at the left end of the channel 101, and a tension spring 15 is fixedly provided between the left end of the unloading slider 12 and the end plate 14. The tension spring 15 is used to force the unloading slider 12 to move to the left. A vertical protrusion 121 extending upward from the feed inlet 1a1 is fixedly provided at the right end of the unloading slider 12. When the guide wheel 3 swings counterclockwise, the guide wheel 3 pushes the vertical protrusion 121 to drive the unloading slider 12 to move to the right. When the guide wheel 3 swings counterclockwise to the lowest position, the vertical protrusion 121 abuts against the right end of the feed inlet 1a1. When the guide wheel 3 swings clockwise, the unloading slider 12 moves to the left under the action of the tension spring 15. When the guide wheel 3 swings clockwise to the processing position, the vertical protrusion 121 abuts against the right end of the feed inlet 1a1. The straight convex plate 121 abuts against the left end of the feed inlet 1a1; the feed slider 12 is provided with a groove 12a with an upper opening, and a protrusion 16 is provided in the groove 12a near the right end. An oil groove 122 is formed in the groove 12a on the left side of the protrusion 16, and the oil groove 122 is provided with cooling oil. The left end of the protrusion 16 is provided with an inclined surface 16a extending from the upper end of the protrusion 16 to the bottom of the groove 12a. The protrusion 16 is provided with a vertical slot 16b near the right end. The bottom of the groove 12a is provided with a connecting groove 123 that communicates with the lower end of the vertical slot 16b. The plate 1d is provided with a feed inlet 1e that runs vertically through the plate. A pushing component is provided on the inner side of the top plate. When the unloading slider 12 moves to the left, the linear bearing bush 7 pushed by the pushing component into the oil groove 122 passes through the inclined surface 16a and the top surface of the protrusion 16 and enters the vertical slot 16b and falls into the connecting groove 123. Since the connecting groove 123 is offset from the unloading port 1e, the linear bearing bush 7 is located on the plate 1d at this time. When the unloading slider 12 moves to the right, the unloading slider 12 drives the linear bearing bush 7 in the connecting groove 123 to move to the right. When the vertical protrusion 121 moves to the right end of the feed port 1a1, the linear bearing bush 7 enters the unloading port 1e and is sent out.

[0039] The pushing assembly includes a pushing filter plate 17. Two vertically extending guide rods 18 are fixedly mounted on the lower end face of the top plate 1a. The pushing filter plate 17 is slidably connected between the lower ends of the two guide rods 18 in a vertical direction. Under the action of gravity, the lower end of the pushing filter plate 17 abuts against the bottom of the groove 12a, the inclined surface 16a, or the top surface 16c of the protrusion 16. The lower end of the pushing filter plate 17 is provided with a guide slope 17a. When the unloading slider 12 moves to the left, the guide slope 17a abuts against the inclined surface 16a. As the unloading slider 12 continues to move to the left, the guide slope and the inclined surface 16a cooperate to move the pushing filter plate 17 upwards. Here, when the pushing filter plate 17 moves in the oil tank 122, cooling oil can pass through the pushing filter plate 17.

[0040] The plate 1d has an oil filter trough 1f with an upper opening on the left side of the feed port 1e. The bottom of the oil filter trough 1f is threaded with a screw plug 19. An oil filter plate 20 is fixedly installed at the upper opening of the oil filter trough 1f. The upper surface of the oil filter plate 20 is 1 mm lower than the upper surface of the plate 1d. Here, the upper surface of the oil filter plate 20 is lower than the upper surface of the plate 1d, so that the cooling oil can be more concentrated and flow into the oil filter trough 1f. When the vertical convex plate 121 abuts against the left end of the feed port 1a1, the linear bearing bushing 7 entering the connecting groove 123 is on the oil filter plate 20. By setting up the oil filter plate 20 and the oil filter tank 1f, when the next linear bearing bush 7 is processed within a set time, the cooling oil adhering to the processed linear bearing bush 7 in the connecting groove 123 enters the oil filter tank 1f through the oil filter plate 20, which greatly reduces the amount of cooling oil adhering to the processed linear bearing bush 7; after a certain amount of cooling oil has accumulated in the oil filter tank 1f, the screw plug 19 can be opened to release the cooling oil in the oil filter tank 1f.

[0041] This embodiment also provides a working method for the above-mentioned linear bearing bushing external cylindrical grinding equipment, including the following steps:

[0042] S1. Control the guide wheel 3 to swing clockwise to the processing position, place the linear bearing bush 7 to be processed on the support plate 4, and the external thread 7a of the linear bearing bush 7 is located in the clearance groove 4a and the clearance ring groove 32, and the rear end face of the linear bearing bush 7 abuts against the stop block 4b.

[0043] S2. Start the third motor 11 to drive the guide wheel 3 to rotate, and at the same time start the first motor 5 to drive the grinding wheel 2 to rotate. Both the guide wheel 3 and the grinding wheel 2 rotate clockwise, thereby grinding the outer circle of the linear bearing bush 7. After the grinding time is set, the linear bearing bush 7 is processed and the guide wheel 3 and the grinding wheel 2 are controlled to stop rotating.

[0044] S3. Control the guide wheel 3 to swing counterclockwise. The processed linear bearing bush 7 moves downward along the arc-shaped inclined plane 13a under its own gravity. When the linear bearing bush 7 moves downward, the external thread 7a is in the arc-shaped clearance opening 13b. At the same time, the guide wheel 3 drives the unloading slider 12 to move to the right through the vertical convex plate 121. When the vertical convex plate 121 moves to the right end of the feed port 1a1, the processed linear bearing bush 7 enters the oil tank 122 from the feed port 1a1 and is located on the right side of the push filter plate 17, where it is cooled by cooling oil.

[0045] S4. Control the guide wheel 3 to swing clockwise to the processing position. The unloading slider 12 moves to the left under the action of the tension spring 15. The pushing component pushes the linear bearing bush 7 processed in the oil groove 122 to the top surface of the protrusion 16. When the vertical protrusion 121 moves to the left end of the feeding port, the pushing component pushes the processed linear bearing bush 7 into the vertical slot hole 16b and falls into the connecting groove 123. At this time, the processed linear bearing bush 7 is on the oil filter plate 20.

[0046] S5. Repeat S1 to S3. When the vertical convex plate 121 moves to the right end of the feed port 1a1, the unloading slider 12 drives the finished linear bearing bush 7 above the oil filter plate 20 to move to the right to the unloading port 1e through the connecting groove 123 and is sent out from the unloading port 1e. At this time, the newly finished linear bearing bush 7 enters the oil tank 122 from the feed port 1a1 and is located on the right side of the push filter plate 17.

[0047] By repeating the above steps, the unloading slider 12, which works in conjunction with the guide wheel 3, and the pushing component that works in conjunction with the unloading slider 12, can automatically unload, cool, and deliver the processed linear bearing bush 7 as the guide wheel 3 swings, which greatly improves processing efficiency and saves labor costs.

[0048] In the above steps, when the guide wheel 3 swings clockwise or counterclockwise, the second motor 10 drives the upper shaft 6 to rotate, the upper shaft 6 drives the connecting plate 8 to swing, and then drives the guide wheel 3 installed at the end of the connecting plate 8 to swing.

[0049] In the above steps, when the pushing component is working, as the unloading slider 12 moves to the left, the pushing filter plate 17 always moves downward under the action of gravity, and the guide inclined surface 17a abuts against the inclined surface 16a. As the unloading slider 12 continues to move to the left, the guide inclined surface 17a and the inclined surface 16a cooperate to move the pushing filter plate 17 upward. During this process, the pushing filter plate 17 pushes the processed linear bearing bush 7 on the right side to the right. The linear bearing bush 7 moves past the inclined surface 16a to the top surface of the protrusion 16 and enters the vertical slot 16b. During the unloading slider 12's movement to the right, the pushing filter plate 17 always moves downward under the action of gravity, passing the top surface of the protrusion 16, the inclined surface 16a, and the bottom surface of the oil groove 122 to the left end of the oil groove 122.

[0050] 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.

The lower end of the pushing filter plate is provided with a guide slope. When the feeding slider moves to the left, the guide slope abuts against the inclined surface. As the feeding slider continues to move to the left, the guide slope and the inclined surface cooperate to push the filter plate upward.

5. The linear bearing bushing external cylindrical grinding equipment according to claim 1, characterized in that, The plate has an oil filter groove with an upper opening on the left side of the feed inlet. The bottom of the oil filter groove is threaded with a plug. An oil filter plate is fixedly installed at the upper opening of the oil filter groove. The upper surface of the oil filter plate is 1 mm lower than the upper surface of the plate. When the vertical convex plate abuts against the left end of the feed inlet, the linear bearing bushing entering the connecting groove is on the oil filter plate.

6. The linear bearing bushing external cylindrical grinding equipment according to claim 1, characterized in that, The guide block has an arc-shaped clearance opening on its curved inclined surface.

7. A method for operating the linear bearing bushing external cylindrical grinding equipment as described in claim 5, characterized in that, Includes the following steps: S1. Control the guide wheel to swing clockwise to the processing position, place the linear bearing bushing to be processed on the support plate, and ensure that the external thread of the linear bearing bushing is located in the clearance groove and clearance ring groove, and the rear end face of the linear bearing bushing abuts against the protrusion. S2. Start the guide wheel and grinding wheel to grind the outer diameter of the linear bearing bushing; after the grinding time is set, the linear bearing bushing is finished, and control the guide wheel and grinding wheel to stop rotating; S3. Control the guide wheel to swing counterclockwise. The processed linear bearing bushing moves downward along the arc-shaped inclined plane under its own gravity. At the same time, the guide wheel drives the unloading slider to move to the right through the vertical convex plate. When the vertical convex plate moves to the right end of the feed port, the processed linear bearing bushing enters the oil tank through the feed port and is cooled by the cooling oil. S4. Control the guide wheel to swing clockwise towards the processing position. The unloading slider moves to the left under the action of the tension spring. The pushing component pushes the processed linear bearing bushing in the oil groove to the top surface of the protrusion. When the vertical protrusion moves to the left end of the feeding port, the pushing component pushes the processed linear bearing bushing into the vertical slot and falls into the connecting slot. At this time, the processed linear bearing bushing is on the oil filter plate. S5. Repeat S1 to S3. When the vertical convex plate moves to the right end of the feed port, the unloading slider drives the finished linear bearing bush above the oil filter plate to move to the right through the connecting groove and is sent out from the unloading port. At this time, the newly finished linear bearing bush enters the oil tank from the feed port.
