Description

Technical Field

[0001] The utility model relates to the technical field of bearing ring processing, in particular to a device for quickly replacing workpieces. Background Art

[0002] On-site processing of large-size bearing inner and outer rings uses a vertical grinder. The vertical grinder has multiple radial grooves on its magnetic disk. Each groove is connected to a fulcrum by sliding inside. During processing, the bearing ring is placed flat on the fulcrum. During processing, the fulcrum is magnetized and the bearing ring is attracted by magnetic force for processing.

[0003] However, due to the varying outer diameters of different bearing rings and the need to process different products, the pivot point position must be adjusted along the radial guideway. During this adjustment process, a tape measure is first used to determine the pivot point's desired position before adjustment. Multiple pivot points must be moved one by one using the tape measure, and a single pivot point requires multiple measurements during the adjustment process, making the operation cumbersome and inefficient. Furthermore, since errors may occur each time the operator visually inspects the tape measure and makes judgments, there's no guarantee that the pivot point will be in the same radial position each time it is adjusted, potentially affecting the stability of the bearing ring's installation. Utility Model Content

[0004] In view of the defects of the prior art, the utility model provides a device for quickly replacing workpieces, which facilitates the adjustment of the position of the fulcrum on the magnetic disk. There is no need to measure the fulcrum one by one. When replacing annular workpieces of different sizes, it is only necessary to readjust the distance between the push plate and the partition, thereby further improving the efficiency of replacing workpieces.

[0005] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is a device for quickly replacing workpieces, which is used for processing annular workpieces on a vertical grinder. The vertical grinder includes a magnetic disk and a fulcrum arranged on the magnetic disk, which includes a connecting rod, a push plate, a partition, and a pressure cap; the push plate is detachably connected to one end of the connecting rod, and the push plate has a first abutment surface, which is used to abut the fulcrum; the partition is installed on the connecting rod and can move along the connecting rod toward or away from the push plate, and the partition has a second abutment surface, which is used to abut the outer diameter surface of the magnetic disk; the pressure cap is installed on the partition to lock the partition and the connecting rod, and lock the radial distance between the first abutment surface and the second abutment surface.

[0006] Furthermore, a size scale is provided on the connecting rod, and the value of the size scale increases from one end connected to the push plate to the other end.

[0007] Furthermore, the axial direction of the connecting rod is parallel to the radial direction of the annular workpiece.

[0008] Furthermore, the first abutting surface and the second abutting surface are both perpendicular to the axial direction of the connecting rod.

[0009] Furthermore, the first abutment surface is flush with the end surface of the connecting rod.

[0010] Furthermore, the size scale corresponding to the first abutting surface on the connecting rod is zero.

[0011] Furthermore, the connecting rod is threadedly connected to the push plate.

[0012] Furthermore, the pressure cap includes a tightening rod, the partition is provided with a threaded hole, and the end of the tightening rod is screwed into the threaded hole and presses the connecting rod.

[0013] Furthermore, a handle is fixed to the other end of the tightening rod.

[0014] The beneficial effects of the present invention are as follows: by setting a connecting rod, a push plate and a partition, the position of the fulcrum is positioned by the push plate, and the outer diameter surface of the magnetic disk is positioned by the partition. Before measurement, the position of the partition on the connecting rod is adjusted and locked, and then the distance between the push plate and the partition is determined. Based on this distance, the position of the fulcrum on the magnetic disk is adjusted. It is only necessary to position the push plate and the partition once to adjust the position of multiple fulcrums on the magnetic disk. The adjustment basis of each fulcrum is unified, and the adjustment is more accurate and fast. When annular workpieces of different sizes need to be replaced, it is only necessary to readjust the distance between the push plate and the partition, which further improves the efficiency of replacing workpieces.

[0029] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] See also Figure 1 , shows a device for quickly replacing workpieces in one embodiment of the utility model, which is used for processing annular workpieces on a vertical grinder. In this embodiment, the processed annular workpiece includes a bearing ring 30, and the vertical grinder includes a magnetic disk 20 and a fulcrum 10 arranged on the magnetic disk 20. During processing, the magnetic disk 20 and the fulcrum 10 are magnetized, and the bearing ring 30 is attracted by magnetic force for processing.

[0031] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4, a device for quickly replacing workpieces includes a connecting rod 100, a push plate 200, a partition 300 and a pressure cap 400; the push plate 200 is detachably connected to one end of the connecting rod 100. In this embodiment, the detachable connection method is to open a threaded hole on the push plate 200, and an external thread is set at the end of the connecting rod 100. The two are threadedly connected. The push plate 200 has a first abutting surface 210, and the first abutting surface 210 is used to abut the fulcrum 10; the partition 300 is installed on the connecting rod 100 and can move along the connecting rod 100 toward or away from the push plate 200. The partition 300 has a second abutting surface 310, and the second abutting surface 310 is used to abut the outer diameter surface 21 of the magnetic disk 20; the pressure cap 400 is installed on the partition 300 to lock the partition 300 and the connecting rod 100, and lock the radial distance between the first abutting surface 210 and the second abutting surface 310.

[0032] During use, the distance between the first abutting surface 210 and the second abutting surface 310 is calculated based on the diameter of the magnetic disk 20, the size of the fulcrum 10, and the size of the bearing ring 30 to meet the installation requirements. After adjusting the relative position of the partition 300 on the connecting rod 100, the partition 300 and the connecting rod 100 are locked with the pressure cap 400. The first abutting surface 210 of the push plate 200 is abutted against the fulcrum 10, and the fulcrum 10 is pushed radially until the second abutting surface 310 of the partition 300 abuts against the outer diameter surface 21 of the magnetic disk 20. This determines that the fulcrum 10 is adjusted into place. Using this adjusted device for quickly changing workpieces, the position of each fulcrum 10 is adjusted in turn.

[0033] It should be noted that since the diameter of the magnetic disk 20 is fixed, the size of the bearing ring 30 can be found from the drawings. The size of the fulcrum 10 on the magnetic disk 20 is fixed, so the distance between the fulcrum 10 and the outer diameter surface 21 at the outermost end of the magnetic disk 20 can be calculated. For example: the outer diameter of the bearing ring 30 is 780mm, and the outer diameter of the magnetic disk is 1000mm. According to the formula (1000-780) / 2=110mm, the distance between the outer diameter of the bearing ring 30 and the outermost side of the magnetic disk 20 is 110mm. The outer diameter contacts the uppermost plane of the fulcrum 10. The distance L between the outermost side of the fulcrum 10 and the outermost side of the uppermost end is 60mm. Therefore, the protruding length of the connecting rod is 110mm-60mm = 50mm. It should be noted that the protruding length of the connecting rod is the radial distance between the first abutting surface 210 and the second abutting surface 310 that needs to be adjusted.

[0034] The above-mentioned device for quickly replacing workpieces is provided with a connecting rod 100, a push plate 200 and a partition 300. The push plate 200 is used to locate the position of the fulcrum 10, and the partition 300 is used to locate the outer diameter surface 21 of the magnetic disk 20. Before measurement, the distance between the push plate 200 and the partition 300 is adjusted, and the position of the fulcrum 10 is adjusted based on this distance. It is only necessary to locate the position of the push plate 200 and the partition 300 once, and the position of multiple fulcrums 10 on the magnetic disk 20 can be adjusted. The adjustment basis of each fulcrum 10 is unified, and the adjustment is more accurate and fast. When annular workpieces of different sizes need to be replaced, it is only necessary to readjust the distance between the push plate 200 and the partition 300, thereby further improving the efficiency of replacing workpieces.

[0035] Furthermore, in one embodiment, a size scale is provided on the connecting rod 100, and the value of the size scale increases from the end connected to the push plate 200 to the other end. This configuration allows the radial distance between the first abutting surface 210 and the second abutting surface 310 to be adjusted with the help of the size scale provided on the connecting rod 100, which is more convenient and can further improve the efficiency of adjusting and replacing the tooling.

[0036] In one embodiment, the axial direction of the connecting rod 100 is parallel to the radial direction of the annular workpiece.

[0037] See also Figure 3 In one embodiment, the first abutting surface 210 and the second abutting surface 310 are both perpendicular to the axial direction of the connecting rod.

[0038] In one embodiment, the first abutting surface 210 is flush with the end surface of the connecting rod 100 .

[0039] Based on the above embodiment, the size scale corresponding to the first abutting surface 210 on the connecting rod 100 is zero. In the above-mentioned device for quickly changing workpieces, the first abutting surface 210 is flush with the end surface of the connecting rod 100, and the size scale corresponding to the first abutting surface 210 on the connecting rod 100 is zero. Then, the scale on the connecting rod 100 corresponding to the position of the second abutting surface 310 shows the distance between the first abutting surface 210 and the second abutting surface 310.

[0040] See also Figure 5 and Figure 8 In one embodiment, the connecting rod 100 is threadedly connected to the push plate 200. Section A in the figure is the portion connected to the push plate 200. The length of this section is fixed at 8 mm. The dimensions are engraved on the connecting rod 100 starting from the left side. When adjusting the connecting rod 100, it can be directly adjusted according to the engraved dimensions.

[0041] See also Figure 6In one embodiment, the pressure cap 400 includes a tightening rod 410 , and the partition 300 is provided with a threaded hole 320 . The end of the tightening rod 410 is screwed into the threaded hole 320 and presses the connecting rod 100 .

[0042] Furthermore, in one embodiment, a handle 420 is fixed to the other end of the tightening rod 410. In this embodiment, the handle 420 is provided to facilitate applying force and rotating the tightening rod 410 to further press the end of the tightening rod 410 against the connecting rod 100 to lock the position of the partition 300.

[0043] In this embodiment, by calculating the required protruding length of the connecting rod 100 and adjusting the spacer 300 on the connecting rod 100 to that position, the fulcrum 10 can be moved successfully in one go, thereby improving production efficiency. In addition, the push plate 200 has the same dimensions as the contact surface of the fulcrum 10, which allows for uniform force during the pushing process, making the fulcrum 10 easier to move and faster.
