Description

Technical Field

[0001] The utility model belongs to the technical field of machining equipment, and specifically belongs to a multi-stage grinding equipment. Background Art

[0002] During the process of finishing ceramic and metal workpieces, in order to meet the usage requirements, some surfaces or end faces often need to be processed by grinding equipment to make the surfaces of the workpieces reach a certain precision.

[0003] At present, the grinding equipment for processing the end faces of ceramic and metal workpieces can be divided into three types:

[0004] The first type is a horizontal spindle rectangular table grinding machine. When this equipment processes the end face of a ceramic or metal workpiece, the workpiece is placed on a rectangular worktable set on the equipment. The rectangular worktable fixes the workpiece through electromagnetic suction, and then drives the rectangular worktable to reciprocate under the grinding wheel in the equipment, so that the grinding wheel rotates for grinding.

[0005] The second type is a vertical spindle circular table grinding machine. When this equipment processes the end face of a ceramic or metal workpiece, the workpiece is placed on a circular worktable. The circular worktable fixes the workpiece through electromagnetic suction, rotates the circular worktable, and the grinding wheel rotates in the opposite direction, and then moves towards the workpiece for grinding.

[0006] The third type is double-sided grinding: When this equipment processes the end face of a ceramic or metal workpiece, the workpiece is clamped by a fixture, and the workpiece is installed between two circular grinding wheels. The two grinding wheels rotate in the opposite or same direction to grind the workpiece.

[0007] Although the above three types of grinding equipment can grind workpieces, a single material (hardness, grain size) grinding wheel is used in the equipment. After processing the workpiece, if the surface roughness of the workpiece does not meet the usage requirements, the workpiece needs to be moved to the equipment with grinding wheels of other materials for grinding again. As a result, the grinding is time-consuming and the production efficiency is low; if the grinding equipment is not replaced, during the grinding process of the workpiece, the grinding amount cannot be effectively controlled, resulting in too much multi-sided grinding amount of the workpiece, and the surface roughness of the workpiece still cannot meet the requirements, causing the workpiece to be scrapped and the production cost to be high. Summary of the Utility Model

[0023] Compared with the prior art, the utility model has the following beneficial technical effects:

[0024] The utility model discloses a multi-stage grinding processing device, which includes a workpiece transfer part and a grinding assembly. The grinding part in the grinding assembly includes a first group of grinding wheels, a second group of grinding wheels and a third group of grinding wheels. The workpiece transferred by the workpiece transfer assembly is successively ground by the first group of grinding wheels, the second group of grinding wheels and the third group of grinding wheels. Since the first group of grinding wheels is composed of coarse-grained grinding wheels, the grinding amount is large, that is, the first group of grinding wheels is for rough grinding. The second group of grinding wheels is composed of medium-grained grinding wheels, so the grinding amount is moderate, that is, the second group of grinding wheels is for medium grinding. The third group of grinding wheels is composed of fine-grained grinding wheels, and the grinding amount is small, that is, the third group of grinding wheels is for fine grinding. By grinding the workpiece in a divided and graded manner by three groups of grinding wheels, it is not necessary to replace the equipment during the processing of the workpiece, that is, the rough and fine grinding of the workpiece end face can be realized, the processing efficiency of the workpiece is improved, and the production cost is reduced.

[0025] Furthermore, a fourth group of grinding wheels is also arranged in the device. The workpieces unqualified detected by the first detector are finely ground again by the fourth group of grinding wheels, so that the end face roughness and the height of some workpieces meet the requirements, the productivity of the workpieces is improved and the production cost is reduced. Moreover, this fine grinding does not affect the continuous processing of other workpieces and can improve the grinding efficiency.

[0026] Furthermore, a detection unit is provided on the mounting base of the device. The detection unit includes a first detector and a second detector. The first detector is used to detect the end face of the workpiece processed by the third group of grinding wheels. If the roughness and height of the workpiece end face meet the requirements, the workpiece is removed; if not, it is transferred to the fourth group of grinding wheels for grinding, and then detected by the second detector. If it is qualified, it is retained; if not, the workpiece is eliminated. By performing two detections, the qualified rate of the workpiece after grinding is further improved, and at the same time, the production efficiency of the workpiece is also increased.

[0027] Furthermore, a moving unit is provided on the sliding seat of the device. The moving unit includes a lead screw and a second starting motor. The second driving motor drives the lead screw to rotate, and then cooperates with the connecting platform to move the sliding seat, so that the sliding seat moves towards the power disk, realizing the grinding feed of the grinding unit. Through the cooperation of the lead screw and the connecting platform, the sliding seat can move stably, improving the stability of the grinding feed of the grinding unit.

[0028] Furthermore, limiting parts are provided on both sides of the moving part on the sliding seat. The limiting parts include a limiting platform and a limiting groove. Through the cooperation of the limiting platform and the limiting groove, the sliding seat can stably slide on the connecting seat or the mounting base, ensuring the stability of the movement of the sliding seat 80 and the stable grinding feed amount during the processing of the grinding unit 1.

[0029] Furthermore, the first driving part is two first driving motors arranged at both ends of a transmission shaft. The two driving motors drive a connecting shaft to rotate simultaneously, and then drive the power disk to rotate, so that the power disk can rotate evenly and stably, ensuring the stability of the transmission of the power disk to the workpiece.

[0030] Furthermore, the clamping part includes a first clamping plate and a second clamping plate. The first clamping plate and the second clamping plate are in a "V" shape structure, and the V-shaped openings of the first clamping plate and the second clamping plate face each other. The workpiece can be well clamped by the first clamping plate and the second clamping plate, making the clamping of the workpiece stable.

[0031] Furthermore, the adjusting part adopts an electric telescopic rod. Through the electric telescopic rod, the distance between the second clamping plate and the first clamping plate can be quickly adjusted, so that the clamping part can quickly clamp and release the workpiece; at the same time, due to its convenient structure and the ability to accurately control the moving distance of the second clamping plate, the electric telescopic rod can avoid the distance between the first clamping plate and the second clamping plate being too close, causing damage to the outer wall of the workpiece, and can make the clamping part clamp the workpiece well.

The workpiece 4 is clamped by the workpiece transmission assembly and then transmitted. During the transmission process, after the workpiece transmission assembly transmits the workpiece 4 to an appropriate position, the grinding assemblies are then driven to move towards the end face of the workpiece 4 on the workpiece transmission assembly to grind the end face of the workpiece 4.

[0046] See Figure 1 , Figure 2 , Figure 5 and Figure 6, the workpiece transfer assembly includes a power disk 2 and a clamping portion 7.

The workpiece 4 is clamped by the clamping portion 7, and the workpiece 4 is transferred by the rotation of the power disk 2 to transfer the workpiece 4 to the machining position.

[0047] See Figure 2 , the first driving portion 5 includes a transmission shaft 53. The transmission shaft 53 is installed at the center position of the power disk 2. The two ends of the transmission shaft 53 are respectively connected to the output shafts of a first driving motor 50 through couplings 51. The first driving motor 50 is installed on the upper end surface of the mounting base 9.

[0048] Preferably, a sleeve 52 is sleeved on the transmission shaft 53. The sleeve 52 is located between the mounting base 9 and the end surface of the power disk 2. The power disk 2 is fixed on the transmission shaft 53 through the sleeve 52 to prevent it from moving along the axial direction of the transmission shaft 53 during the rotation of the transmission shaft 53, affecting the use of the device.

[0049] See Figure 2 、 Figure 5 and Figure 6 , the clamping portion 7 includes a first clamping plate 70 and a second clamping plate 71. Both the first clamping plate 70 and the second clamping plate 71 are in a "V" shape. The first clamping plate 70 is fixedly installed on one side end surface of the mounting groove 20. The second clamping plate 71 is movably installed on the other side end surface in the mounting groove 20, and the "V" mouths of the first clamping plate 70 and the second clamping plate 71 are opposite to each other. An adjusting member 72 is connected thereto. The adjusting member 72 is fixedly installed in the mounting groove 20. The adjusting member 72 is used to adjust the distance between the second clamping plate 71 and the first clamping plate 70 to realize the clamping and loosening of the workpiece 4. In this embodiment, the adjusting member 72 is an electric telescopic rod.

[0050] See Figures 1 to 4 , the grinding assembly includes a grinding portion 1 and a detection portion 3. Both the grinding portion 1 and the detection portion 3 are installed on the mounting base 9. The grinding portion 1 is used to grind the end surface of the workpiece 4 clamped by the clamping portion 7 on the power disk 2 to make the surface roughness of the end surface of the workpiece 4 meet the requirements;

[0051] See Figure 1 、 Figure 3 and Figure 4, on the upper end surface of the mounting base 9, connecting seats 6 are respectively arranged on both sides of the power disk 2. A plurality of second driving parts 8 are installed on the connecting seats 6, and the second driving parts 8 are also installed on the mounting base 9. Each second driving part 8 is connected with a grinding part 1. Through the second driving part 8, the grinding part 1 moves towards the end face of the workpiece 4 clamped on the power disk 2. At the same time, through the second driving part 8, the grinding part 1 is also driven to rotate to grind the end face of the workpiece 4.

[0052] See Figure 1 and Figure 3 , the grinding part 1 includes a first group of grinding wheels 10, a second group of grinding wheels 11, a third group of grinding wheels 12 and a fourth group of grinding wheels 13. Among them, there are two grinding wheels inside the first group of grinding wheels 10, the second group of grinding wheels 11, the third group of grinding wheels 12 and the fourth group of grinding wheels 13. After the two grinding wheels are connected by the second driving part 8, they are symmetrical about the power disk 2.

[0053] A third driving motor 85 is connected to each of the first group of grinding wheels 10, the second group of grinding wheels 11, the third group of grinding wheels 12, and the fourth group of grinding wheels 13. The output shaft of the third driving motor 85 is connected to the first group of grinding wheels 10, the second group of grinding wheels 11, the third group of grinding wheels 12, and the fourth group of grinding wheels 13.

The third driving motor 85 connected to the second group of grinding wheels 11 is located between the third driving motors 85 connected to the first group of grinding wheels 10 and the third group of grinding wheels 12. The first group of grinding wheels 10 is composed of two coarse-grained grinding wheels, and the grain size of the coarse-grained grinding wheels is 16# - 24#. The two coarse-grained grinding wheels are used to simultaneously perform the first-step grinding process on the two end faces of the same workpiece 4 clamped on the power disk 2. The amount of machining on the end face of the workpiece 4 by this coarse-grained grinding wheel is large, which is rough grinding in the grinding process. The second group of grinding wheels 11 consists of two medium-grained grinding wheels, and the grain size of the medium-grained grinding wheels is 60# - 120#. The two medium-grained grinding wheels are used to simultaneously perform the second-step grinding process on the two end faces of the same workpiece 4 clamped on the power disk 2. The amount of machining on the end face of the workpiece 4 by this medium-grained grinding wheel is moderate, which is medium grinding in the grinding process. The third group of grinding wheels 12 is composed of two fine-grained grinding wheels, and the grain size of the fine-grained grinding wheels is 180# - 320#. The two fine-grained grinding wheels are used to simultaneously perform the third-step grinding process on the two end faces of the same workpiece 4 clamped on the power disk 2. The amount of machining by this fine-grained grinding wheel is the least, which is finish grinding in the grinding process. After the end faces of the workpiece 4 are ground by the first group of grinding wheels 10, the second group of grinding wheels 11, and the third group of grinding wheels 12, the roughness of the end faces reaches the requirements. If it is detected that the roughness of the end faces of the workpiece 4 does not meet the requirements, then the fourth group of grinding wheels 13 is used for grinding. The fourth group of grinding wheels 13 is composed of two fine-grained grinding wheels, and the two fine-grained grinding wheels are used to simultaneously perform the fourth-step grinding process on the two end faces of the same workpiece 4 clamped on the power disk 2, machining the end faces of the workpiece 4 to the required roughness. In this device, the machining of the workpiece 4 is carried out by a hierarchical grinding method. This grinding method has high efficiency and can complete the rough and finish grinding of the workpiece 4 through one device. During the rough and finish machining processes, there is no need to replace the equipment and re-clamp the workpiece 4, which greatly saves the machining time and improves the machining efficiency.

The second driving part 8 rotates the lead screw 83 through the second driving motor 84, and then the lead screw 83 drives the connecting table 82 to move on the lead screw 83, thereby driving the sliding seat 80 to move on the connecting seat 6. After the workpiece 4 clamped on the power disk 2 rotates to its corresponding position, the sliding seat 80 drives the third driving motor 85 thereon to move towards the power disk 2, and then drives the grinding part 1 to rotate through the third driving motor 85 to grind the workpiece 4.

[0056] See Figure 3 , a limiting part is provided on the bottom end surface of each sliding seat 80. The limiting parts are distributed on both sides of the moving part.

A limiting groove is provided at a position on the connecting seat 6 or the mounting seat 9 corresponding to the limiting platform 81. The vertical cross-sectional shape of the limiting groove is the same as the vertical cross-sectional shape of the limiting platform 81. The limiting platform 81 is slidably installed in the limiting groove for limiting the sliding seat 80 so that it can only move towards or away from the power disk 2, ensuring the stability of the sliding seat movement and the stable grinding feed amount during the processing of the grinding part.

[0057] See Figure 1, a detection unit 3 is installed on the mounting base 9. The detection unit 3 includes a first detector 30 and a second detector 31.

The second detector 31 is arranged on the left side of the fourth group of grinding wheels 13, that is, between the fourth group of grinding wheels 13 and the first group of grinding wheels 10. The first detector 30 is used to detect the end face of the workpiece 4 processed by the third group of grinding wheels 12. If the roughness and height of the end face of the workpiece 4 meet the requirements, the workpiece 4 clamped by the clamping part 7 on the power disk 2 is removed. If it is detected that the roughness and height of the end face of the workpiece 4 do not meet the requirements, the workpiece 4 is transmitted to the position of the fourth group of grinding wheels 13 by the power disk 2 for grinding. After the grinding is completed, it is detected by the second detector 31. If the roughness of the end face of the workpiece 4 and the height of the workpiece 4 meet the requirements, the workpiece 4 is retained. If the roughness of the end face of the workpiece 4 and the height of the workpiece 4 do not meet the requirements, the workpiece 4 is eliminated.
