Description

Technical Field

[0001] This application relates to the field of machining equipment technology, and in particular to a vertical spindle grinding machine. Background Technology

[0002] A vertical spindle grinder is a machine tool in which a vertical spindle drives a grinding wheel to perform grinding operations. Its core feature is that the spindle is arranged vertically and the axis of the grinding head is perpendicular to the conveying surface of the feeding mechanism. It is suitable for mass production or high-precision machining applications.

[0003] However, vertical spindle grinding machines typically use flexible PVC conveyor belts to transport the workpiece. When the grinding head strikes the workpiece on the flexible PVC conveyor belt, the belt is prone to indentation, making it impossible to grind workpieces less than 2mm thick. Furthermore, the flexible PVC conveyor belt cannot serve as a hard reference, resulting in poor grinding accuracy and inconsistent product quality. Therefore, current vertical spindle grinding machines suffer from poor grinding capability and accuracy. Utility Model Content

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] See Figure 1 and Figure 2 The diagram shows a schematic of the structure of a vertical spindle grinding machine according to an embodiment of the present application. The vertical spindle grinding machine includes a bed frame 100, a grinding mechanism 200, a feeding mechanism 300 and a pressing mechanism 400. The bed frame 100 is provided with a first mounting position 100A and a second mounting position 100B.

[0038] The grinding mechanism 200 is installed at the first mounting position 100A. The grinding mechanism 200 includes a first drive unit 210, a spindle assembly 220 and a grinding head 230. The first drive unit 210 is installed on the bed frame 100. The spindle assembly 220 is movably installed on the bed frame 100. The spindle assembly 220 is drivenly connected to the first drive unit 210 and connected to the grinding head 230.

[0039] The feeding mechanism 300 is installed in the second mounting position 100B. The feeding mechanism 300 includes a second drive unit 310, a drive wheel 320, a driven wheel 330, and a chain belt 340. The drive wheel 320 and the driven wheel 330 are rotatably mounted on the bed frame 100. The chain belt 340 is sleeved on the drive wheel 320 and the driven wheel 330 and is connected to the drive wheel 320. The second drive unit 310 is installed on the bed frame 100 and is drivenly connected to the drive wheel 320. The chain belt 340 is provided with a conveying surface 341. The conveying surface 341 is arranged opposite to the grinding head 230 of the grinding mechanism 200. The conveying surface 341 is used to convey the workpiece 10 to be processed.

[0040] The pressing mechanism 400 is installed on the bed frame 100 and is set on the conveying surface 341. The pressing mechanism 400 is used to press the workpiece 10 to be processed during conveying.

[0041] It should be noted that, as Figure 1 As shown, the X-axis, Y-axis and Z-axis form a spatial rectangular coordinate system. The X-axis is set along the conveying direction of the workpiece 10 to be processed, and the Z-axis is in the vertical direction.

[0042] In an optional embodiment, such as Figure 1 and Figure 2 As shown, the first mounting position 100A and the second mounting position 100B are distributed along the Z-axis direction, so that the grinding mechanism 200 is mounted above the feeding mechanism 300. The grinding end face of the grinding mechanism 200 is positioned opposite to the conveying surface 341 of the feeding mechanism 300, so that when the conveying surface 341 conveys the workpiece 10 to be processed, the grinding mechanism 200 can grind the workpiece 10. The pressing mechanism 400 is positioned upstream of the feeding mechanism 300 along the X-axis direction. When the feeding mechanism 300 needs to convey the workpiece 10 to be processed to the grinding mechanism 200 for grinding, the pressing mechanism 400 presses the workpiece 10 to be processed, which can prevent the workpiece 10 to be processed from being displaced or overturned under the grinding force of the grinding mechanism 200, and ensure the stability, accuracy and continuity of the workpiece 10 to be processed during the grinding process.

[0043] The vertical spindle grinder described in this application embodiment has a grinding mechanism 200 and a feeding mechanism 300 on the bed frame 100. The feeding mechanism 300 sleeves the chain belt 340 on the drive wheel 320 and the driven wheel 330. The second drive unit 310 drives the drive wheel 320 to rotate, thereby driving the chain belt 340 to rotate and placing the workpiece 10 to be processed on the conveying surface 341 of the chain belt 340, thereby conveying the workpiece 10 to be processed to the grinding mechanism 200. The first drive unit 210 drives the grinding head 230 to rotate through the spindle assembly 220, thereby grinding the workpiece 10 to be processed on the conveying surface 341. The chain belt 340 is provided with a pressing mechanism 400, which can press the workpiece 10 to be processed on the conveying surface 341 during conveying, thereby improving the processing quality.

[0044] The vertical spindle grinder described in this application uses a chain belt 340 to transport the workpiece 10 to be processed. Compared with a soft PVC conveyor belt, the chain belt 340 has higher strength. When the grinding head 230 acts on the workpiece 10 to perform grinding, the chain belt 340 is less likely to sink, thus it can grind the workpiece 10 with a thickness of 2mm. Moreover, the more accurate bearing position of the chain belt 340 can improve the grinding accuracy, and it has the advantages of high processing limit and high precision.

[0045] Combination Figure 5The diagram shows an enlarged view of the mounting groove 100C of a vertical spindle grinder according to one embodiment of the present application. In some embodiments, the bed frame 100 is provided with the mounting groove 100C, the drive wheel 320 is provided at one end of the mounting groove 100C, the driven wheel 330 is provided at the other end of the mounting groove 100C, and the feeding mechanism 300 also includes a support plate 350. The support plate 350 is provided in the mounting groove 100C and is located on the side of the chain belt 340 away from the conveying surface 341. Reference members 351 are provided on both sides of the support plate 350, and the chain belt 340 slidably abuts against the reference members 351.

[0046] In one exemplary embodiment, the length extension direction of the mounting groove 100C is set along the X-axis direction.

[0047] In this embodiment, the feeding mechanism 300 is installed in the mounting slot 100C of the bed frame 100. The second drive unit 310 drives the chain belt 340 to rotate cyclically on the drive wheel 320 and the driven wheel 330. A support plate 350 is provided at the bottom of the chain belt 340 relative to the conveying surface 341, and the chain belt 340 is supported on the support plate 350. Specifically, the two sides of the chain belt 340 slide against the reference member 351 of the support plate 350, so that the reference member 351 provides a hard reference for the chain belt 340, avoiding inward displacement of the chain belt 340 when supporting the workpiece 10 for processing, thereby improving the processing accuracy and ensuring stable dimensional and positional tolerances.

[0048] The vertical spindle grinding machine described in this application embodiment can improve the machining accuracy to ±0.01mm, the product parallelism and flatness to ±0.015mm, the thinnest workpiece can be processed to 0.8-1mm, and the maximum grinding amount is 0.5mm.

[0049] In an optional embodiment, the chain 340 is made of stainless steel and the reference component 351 is made of alloy, so that the chain 340 and the reference component 351 have a certain strength and improve the processing accuracy.

[0050] In one exemplary embodiment, such as Figure 1 As shown, the first drive unit 210 consists of a first motor and a belt, with the first motor connected to the main shaft assembly 220 via the belt. The second drive unit includes a second motor and an Rv63 reducer, with the second electric mechanism driving the drive wheel 320 to rotate via the Rv63 reducer.

[0051] In an optional embodiment, such as Figure 2 and Figure 3As shown, the pressing mechanism 400 includes a mounting plate 410 and a pressing roller assembly 420. The mounting plate 410 is movably connected to the bed frame 100. The pressing roller assembly 420 includes a first pressing roller 421, a second pressing roller 422, and a third drive unit 423. There are two first pressing rollers 421, which are respectively disposed on both sides of the second pressing roller 422. The first pressing roller 421 is rotatably disposed on the mounting plate 410. The second pressing roller 422 is rotatably disposed on the mounting plate 410. The third drive unit 423 is drivenly connected to the first pressing roller 421. The gap H1 between the first pressing roller 421 and the conveying surface 341 is equal to the gap H2 between the second pressing roller 422 and the conveying surface 341.

[0052] The pressure roller assembly 420 used in conventional vertical spindle grinders is a single pressure roller structure, meaning there is only one pressure roller. As a result, the contact area between the pressure roller and the workpiece 10 to be processed is small, leading to a small thrust of the pressure roller. The workpiece often stops, requiring manual adjustment and resulting in poor product consistency.

[0053] To improve the problem of poor product consistency, this embodiment sets two first pressure rollers 421 as active pressure rollers, which are driven to rotate by the third drive unit 423. A second pressure roller 422 that can rotate freely is also set between the two first pressure rollers 421, so that the three pressure rollers work together to support the workpiece 10 to be processed, increasing the contact area between the pressure roller assembly 420 and the workpiece 10 to be processed, so that the pressure roller assembly 420 can push the workpiece 10 to be processed stably, reducing the poor grinding consistency of the workpiece 10 to be processed due to pauses. The second pressure roller 422 can also prevent the workpiece 10 to be processed from being pressed up by the first pressure roller 421, thus improving the processing quality.

[0054] In an exemplary embodiment, the third drive unit 423 includes a third motor and a reducer. The third motor and reducer are disposed on the side of the mounting plate 410 away from the first pressure roller 421 and the second pressure roller 422. The shaft of the first pressure roller 421 is provided with a first gear, the shaft of the second pressure roller 422 is provided with a second gear, and the output shaft of the reducer is provided with a third gear. The first gear and the second gear have the same specifications, and the first gear and the second gear mesh with the third gear at the same time, thereby ensuring that the first pressure roller 421 and the second pressure roller 422 maintain the same speed and are stable and reliable, and improving the stability of conveying the workpiece 10 to be processed.

[0055] In an optional embodiment, such as Figure 3 As shown, the pressing mechanism 400 also includes a first pressing block assembly 430 and a second pressing block assembly 450. The first pressing block assembly 430 is disposed on one side of the pressing roller assembly 420 along the X-axis direction, and the second pressing block assembly 450 is disposed on the other side of the pressing roller assembly 420 along the X-axis direction.

[0056] The first pressing block assembly 430 includes a first pressing block 431 and a fourth driving unit 432. The fourth driving unit 432 is connected to the mounting plate 410. The first pressing block 431 is spaced apart from the conveying surface 341. The fourth driving unit 432 is drivenly connected to the first pressing block 431. The second pressing block assembly 450 includes a second pressing block 451 and a sixth driving unit 452. The sixth driving unit 452 is connected to the mounting plate 410. The second pressing block 451 is spaced apart from the conveying surface 341. The sixth driving unit 452 is drivenly connected to the second pressing block 451.

[0057] To prevent the workpiece 10 from warping or tilting at the front or back of the pressure roller assembly 420, which could lead to stacking and jamming requiring manual intervention, this embodiment uses a first pressure block assembly 430 at one end of the pressure roller assembly 420 and a second pressure block assembly 450 at the other end. The first pressure block assembly 430 can be driven by a fourth drive unit 432 to move a first pressure block 431 in the Z-axis direction, thereby limiting the height of the input end of the first pressure roller assembly 420. The second pressure block assembly 450 can be driven by a sixth drive unit 452 to move a second pressure block 451 in the Z-axis direction, thereby limiting the height of the output end of the second pressure roller assembly 450. This prevents the workpiece 10 from warping when entering or exiting the pressure roller assembly 420, thus avoiding stacking and reducing poor grinding consistency caused by stacking, resulting in better processing quality.

[0058] In an exemplary embodiment, the fourth drive unit 432 and the sixth drive unit 452 are drive cylinders.

[0059] In an optional embodiment, such as Figure 3 As shown, the pressing mechanism 400 also includes a guide rail 441, an adjusting block 442, and an adjusting rod 443. The guide rail 441 is arranged on the bed frame 100 along the Z-axis direction. The mounting plate 410 is slidably arranged on the guide rail 441. The adjusting block 442 is mounted on the bed frame 100. One end of the adjusting rod 443 is connected to the mounting plate 410. The adjusting rod 443 and the adjusting block 442 are movably connected.

[0060] In this embodiment, the mounting plate 410 and the bed frame 100 are slidably connected by the guide rail 441, and the two are also connected by the adjusting block 442 and the adjusting rod 443. By changing the position of the adjusting block 442 on the adjusting rod 443, the height of the entire pressing mechanism 400 in the Z-axis direction can be adjusted. Thus, the height of the pressing mechanism 400 can be adjusted according to the thickness of the workpiece 10 to be processed, so that the workpiece 10 to be processed can pass smoothly through the pressure roller assembly 420 and the first pressing block assembly 430, which has the advantage of good adaptability.

[0061] In an exemplary embodiment, the adjusting block 442 is provided with a threaded hole, and the adjusting rod 443 is provided with an external thread. The adjusting rod 443 and the adjusting block 442 are connected by threaded engagement. The position of the adjusting rod 443 on the adjusting block 442 is adjusted by rotating the adjusting rod 443, thereby adjusting the position of the pressing mechanism 400.

[0062] In an optional embodiment, such as Figure 2 As shown, the spindle assembly 220 includes a spindle box 221, a spindle 222, and a flange 223. The spindle box 221 is movably mounted on the bed frame 100, and the spindle 222 is rotatably mounted on the spindle box 221. One end of the spindle 222 facing the feeding mechanism 300 is connected to the flange 223, and the grinding head 230 is mounted on the flange 223. By setting the spindle 222 inside the spindle box 221, the first drive unit 210 is connected to one end of the spindle 222, and the grinding head 230 is connected to the other end of the spindle 222 through the flange 223, thereby enabling the first drive unit 210 to drive the grinding head 230 to rotate and perform grinding via the spindle 222.

[0063] Furthermore, in order to improve grinding quality, such as Figure 2 As shown, the grinding mechanism 200 also includes a water outlet 240, which is mounted on the flange 223. The end face of the water outlet 240 is flush with the end face of the grinding head 230. The spindle 222 is provided with a water supply channel 222A, and the end face of the water outlet 240 is provided with multiple water outlet holes 240A. One end of the water supply channel 222A is connected to the water outlet holes 240A, and the other end of the water supply channel 222A is connected to a water source through a water pipe. By setting the water outlet 240 on the grinding end face, water is supplied to the grinding end face of the spindle 222 and the grinding head 230 through the water supply channel 222A and the water outlet 240, thereby cooling the spindle 222 and the grinding head 230 and preventing overheating from affecting the grinding quality.

[0064] In an optional embodiment, to control the grinding mechanism 200 to move along the Z-axis, such as... Figure 4 As shown, the vertical spindle grinding machine also includes a lifting mechanism 500, which includes a lead screw 510, a transmission shaft 520, a worm gear 530, and a fifth drive unit 540. The lead screw 510 is rotatably mounted on the bed frame 100 along the Z-axis. The spindle box 221 is provided with a connecting seat 2211, which has a threaded hole. The connecting seat 2211 is movably connected to the lead screw 510 through the threaded hole. The lead screw 510 is provided with a first gear 511. One end of the transmission shaft 520 is provided with a second gear 521, which meshes with the first gear 511 and the second gear 521. The other end of the transmission shaft 520 is provided with a worm gear 522. The worm gear 530 is rotatably mounted on the bed frame 100 and meshes with the worm gear 522. The fifth drive unit 540 is driven by the worm gear 530.

[0065] In this embodiment, the fifth drive unit 540 drives the worm gear 530 to rotate, thereby driving the transmission shaft 520 meshing with the worm gear 530 to rotate, which in turn drives the lead screw 510 meshing with the first gear 511 and the second gear 521 to rotate. The rotation of the lead screw 510 will cause the connecting seat 2211 to move on the lead screw 510. Since the connecting seat 2211 is connected to the spindle box 221, the fifth drive unit 540 will drive the entire grinding mechanism 200 to move along the Z-axis. When the workpiece 10 to be processed is in the grinding position, the grinding mechanism 200 is controlled to grind the workpiece 10 downwards. After the processing is completed, it moves upwards to unload the workpiece.

[0066] In one exemplary embodiment, such as Figure 4 As shown, the fifth drive unit 540 includes a drive motor 541 and a handwheel 542. The drive motor 541 is connected to one end of the worm gear 530, and the handwheel 542 is connected to the other end of the worm gear 530. By setting the drive motor 541 and the handwheel 542 at both ends of the worm gear 530 respectively, the movement of the grinding mechanism 200 can be electrically controlled by the drive motor 541, and the position of the grinding mechanism 200 can be manually adjusted by the handwheel 542, which can be selected according to the processing requirements.

[0067] In an optional embodiment, such as Figure 4 As shown, the lifting mechanism 500 also includes two first bearings 550 and two second bearings. The two ends of the lead screw 510 are respectively mounted to the bed frame 100 via the first bearings 550, and the two ends of the worm gear 530 are respectively mounted to the bed frame 100 via the second bearings. By placing the lead screw 510 on the first bearings 550 and the worm gear 530 on the second bearings, the rotation of the lead screw 510 and worm gear 530 is made more stable, thereby improving the driving stability of the lifting mechanism 500, and thus improving the accuracy and stability of the driving grinding mechanism 200. It has the advantages of high machining accuracy and good stability.
