Technical Field
[0001] This utility model belongs to the field of grinding machine technology, and in particular relates to a bevel measuring device for grinding machines and a grinding machine. Background Technology
[0002] With the continuous advancement of machining technology, grinding machines are no longer limited to machining flat surfaces; existing grinding machines can also be used to machine inclined surfaces. However, the accuracy of inclined surfaces machined by grinding machines cannot be guaranteed because the accuracy of the inclined surface is directly limited by the accuracy of the grinding machine and the performance of the grinding wheel, making errors uncontrollable. To improve the accuracy of friction-machined inclined surfaces, projectors and coordinate measuring machines (CMMs) are usually used to measure the inclined surface degree of the workpiece. However, projectors and CMMs are relatively expensive. For grinding machines without projectors or CMMs, the inclined surface degree of the workpiece is manually measured using an angle gauge. Since the angle gauge does not have a fixed placement position, it is prone to tilting during the measurement process, resulting in low measurement accuracy. Summary of the Invention
[0003] The present invention addresses the technical problem of low accuracy in measuring inclined planes using angle rulers in the prior art by providing an inclined plane measuring device for a grinding machine and a grinding machine.
[0004] To solve the above-mentioned technical problems, this utility model provides a bevel measuring device for a grinding machine, including a worktable, a height measuring component, a cylinder, and a stop block; the stop block, the height measuring component, and the workpiece to be measured are all placed on the worktable;
[0005] The stop block has a side perpendicular to the worktable, and the side of the stop block abuts against the workpiece to be measured; the cylinder is placed on the inclined surface of the workpiece to be measured, and the cylinder is tangent to the side of the stop block and the inclined surface of the workpiece to be measured; the height measuring device is used to measure the distance between the apex of the cylinder and the worktable.
[0006] Optionally, the height measuring component includes a height gauge, which includes a support frame, a connecting rod mounted on the support frame, and a measuring instrument mounted on the connecting rod. The support frame is mounted on the worktable. The measuring end of the measuring instrument abuts against the apex of the cylinder to measure the distance between the apex of the cylinder and the worktable.
[0007] Optionally, the support frame includes a base and a support rod mounted on the base, and the connecting rod is mounted on the support rod.
[0008] Optionally, the connecting rod is provided with a first through hole and a first fastening hole communicating with the first through hole, and the support rod is inserted into the first through hole; the height gauge further includes a first fastener, which is inserted into the first fastening hole and abuts against the support rod.
[0009] Optionally, the connecting rod is provided with a second through hole and a second fastening hole communicating with the second through hole, and the measuring instrument is inserted into the second through hole; the height gauge also includes a second fastener, which is inserted into the second fastening hole and abuts against the measuring instrument.
[0010] Optionally, the connecting rod includes a fastening sleeve, a first rod body with an inner hole, and a second rod body inserted into the inner hole, wherein the fastening sleeve is sleeved on the second rod body and connected to the first rod body;
[0011] The end of the first rod away from the second rod is mounted on the support frame, and the measuring instrument is mounted on the second rod.
[0012] Optionally, the stop block is provided with a first magnetic attraction part for adsorbing the workpiece to be tested.
[0013] Optionally, the worktable is provided with a second magnetic suction part for adsorbing the stop block and / or the workpiece to be tested.
[0014] Another embodiment of this utility model provides a grinding machine, including the above-described inclined plane measuring device for grinding machines.
[0015] In this invention, when it is necessary to measure the inclined surface of the workpiece, firstly, the stop block is placed tightly against the workpiece, and then the cylinder is placed on the inclined surface of the workpiece. Due to gravity, the cylinder will roll along the inclined surface of the workpiece until the cylinder is tangent to the side of the stop block and the inclined surface of the workpiece. Finally, the distance h between the apex of the cylinder and the worktable is measured using a height measuring device. By comparing h with the standard distance H, it is determined whether the inclined surface meets the requirements.
[0016] The distance between the bottom of the inclined plane and the worktable is a1, the distance between the center of the cylinder and the bottom of the inclined plane is a2, and the distance between the center of the cylinder and the height measuring component is r (r is the radius of the cylinder). a1 and r are known quantities, and a2 can be calculated using trigonometric formulas: a2 = r / tan(d / 2), where d is the angle between the inclined plane of the workpiece to be measured and the side of the stop block, and d is a known quantity. The standard distance between the vertex of the cylinder and the worktable is H, where H = a1 + a2 + a3 = a1 + r(1 ÷ tan(d / 2) + 1).
[0017] When h is less than H, it indicates that the bevel grinding of the workpiece is excessive; when h is greater than H, it indicates that the bevel grinding of the workpiece is insufficient and further grinding is needed; when h equals H, it indicates that the bevel grinding of the workpiece is qualified. In this invention, the bevel measuring device for grinding machines can be used to determine whether the bevel grinding of the workpiece is qualified. This bevel measuring device for grinding machines has a simple structure, low equipment cost, and high measurement accuracy. Attached Figure Description

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0025] It should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.
[0026] like Figure 1As shown, an embodiment of this utility model provides a bevel measuring device for a grinding machine, including a worktable 1, a height measuring component 2, a cylinder 3, and a stop block 4; the stop block 4, the height measuring component 2, and the workpiece 100 to be measured are all placed on the worktable 1; it can be understood that the worktable 1 can be made of marble, so that the worktable 1 has good flatness; the height measuring component 2 includes, but is not limited to, a height gauge, etc.
[0027] The stop block 4 has a side perpendicular to the worktable 1, and the side of the stop block 4 abuts against the workpiece 100 to be tested. The cylinder 3 is placed on the inclined surface of the workpiece 100 to be tested, and the cylinder 3 is tangent to the side of the stop block 4 and the inclined surface of the workpiece 100 to be tested. The height measuring component 2 is used to measure the distance between the apex of the cylinder 3 and the worktable 1. Understandably, when the stop block 4 is placed close to the workpiece 100 to be tested, and the cylinder 3 is placed on the inclined surface of the workpiece 100 to be tested, due to gravity, the cylinder 3 will roll along the inclined surface of the workpiece 100 to be tested until the side of the stop block 4 and the inclined surface of the workpiece 100 to be tested are tangent.
[0028] Specifically, when it is necessary to measure the inclined surface of the workpiece 100, firstly, the stop block 4 is placed tightly against the workpiece 100, and then the cylinder 3 is placed on the inclined surface of the workpiece 100. Due to gravity, the cylinder 3 will roll along the inclined surface of the workpiece 100 until the side of the cylinder 3 and the stop block 4 are tangent to the inclined surface of the workpiece 100. Finally, the distance h between the apex of the cylinder 3 and the worktable 1 is measured using the height measuring device 2. By comparing h with the standard distance H, it is determined whether the inclined surface meets the requirements.
[0029] The distance between the bottom of the inclined plane and the workbench 1 is a1, the distance between the center of the cylinder 3 and the bottom of the inclined plane is a2, and the distance between the center of the cylinder 3 and the height measuring component 2 is r (r is the radius of the cylinder 3). a1 and r are known quantities, and a2 can be calculated using trigonometric formulas: a2 = r / tan(d / 2), where d is the angle between the inclined plane of the workpiece 100 to be measured and the side of the stop block 4, and d is a known quantity. The standard distance between the vertex of the cylinder 3 and the workbench 1 is H, where H = a1 + a2 + a3 = a1 + r(1 ÷ tan(d / 2) + 1).
[0030] When h is less than H, it indicates that the bevel grinding of the workpiece 100 is excessive; when h is greater than H, it indicates that the bevel grinding of the workpiece 100 is insufficient and further grinding is needed; when h equals H, it indicates that the bevel grinding of the workpiece 100 is qualified. In this invention, the bevel measuring device for grinding machines can be used to determine whether the bevel grinding of the workpiece 100 is qualified. This bevel measuring device for grinding machines has a simple structure, low equipment cost, and high measurement accuracy.
[0031] In one embodiment, such as Figure 1 and Figure 2 As shown, the height measuring component 2 includes a height gauge, which comprises a support frame 21, a connecting rod 22 mounted on the support frame 21, and a measuring instrument 23 mounted on the connecting rod 22. The support frame 21 is mounted on the worktable 1. The measuring end of the measuring instrument 23 abuts against the apex of the cylinder 3 to measure the distance between the apex of the cylinder 3 and the worktable 1. Understandably, the height gauge is a tool equipped on a conventional grinding machine, and the measuring end of the measuring instrument 23 abuts against the cylinder 3 to measure the distance between the apex of the cylinder 3 and the worktable 1. In this embodiment, the height measuring instrument 23 is a conventional component, thus this inclined plane measuring device for grinding machines can be applied to conventional grinding machines.
[0032] In one embodiment, such as Figure 1 and Figure 2 As shown, the support frame 21 includes a base 211 and a support rod 212 mounted on the base 211, and the connecting rod 22 is mounted on the support rod 212. Understandably, the support rod 212 is mounted on the top surface of the base 211, the base 211 can be placed on the worktable 1, and the support rod 212 serves to support the connecting rod 22 and the measuring instrument 23.
[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the connecting rod 22 has a first through hole and a first fastening hole communicating with the first through hole, and the support rod 212 is inserted into the first through hole; the height gauge also includes a first fastener 24, which is inserted into the first fastening hole and abuts against the support rod 212. It can be understood that the first fastener 24 includes, but is not limited to, knobs, bolts, etc., and the first fastener 24 can be inserted into the first fastening hole via a threaded structure.
[0034] In this embodiment, the connecting rod 22 can slide along the first through hole (that is, adjust the depth of the connecting rod 22 inserted into the first through hole), thereby adjusting the height of the measuring instrument 23 so that the measuring end of the measuring instrument 23 abuts against the cylinder 3. After the position of the connecting rod 22 on the support rod 212 is adjusted, the first fastener 24 is rotated, and the first fastener 24 can press the connecting rod 22 in the first through hole, thereby fixing the connecting rod 22 on the support rod 212. In this embodiment, the height adjustment of the measuring instrument 23 and the connecting rod 22 is simple.
[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, the connecting rod 22 has a second through hole and a second fastening hole communicating with the second through hole, and the measuring instrument 23 is inserted into the second through hole; the height gauge also includes a second fastener 25, which is inserted into the second fastening hole and abuts against the measuring instrument 23. It can be understood that the second fastener 25 includes, but is not limited to, knobs, bolts, etc., and the second fastener 25 can be inserted into the second fastening hole via a threaded structure.
[0036] In this embodiment, the second fastener 25 can fix the measuring instrument 23 in the second through hole, and can also release the locking state between the connecting rod 22 and the measuring instrument 23. In this embodiment, the measuring instrument 23 can be fixed on the connecting rod 22 by rotating the second fastener 25, and the disassembly and assembly operation between the measuring instrument 23 and the connecting rod 22 is simple.
[0037] In one embodiment, such as Figure 2As shown, the connecting rod 22 includes a fastening sleeve 221, a first rod body 222 with an inner hole, and a second rod body 223 inserted into the inner hole. The fastening sleeve 221 is sleeved on the second rod body 223 and connected to the first rod body 222. The end of the first rod body 222 away from the second rod body 223 is mounted on the support frame 21, and the measuring instrument 23 is mounted on the second rod body 223. Specifically, the first rod body 222 and the second rod body 223 are telescopically connected. By adjusting the depth of the second rod body 223 inserted into the inner hole, the length of the connecting rod 22 can be adjusted, thereby adjusting the distance between the measuring instrument 23 and the support rod 212, so that the height gauge can measure workpieces 100 of different specifications. In addition, after the distance between the first rod 222 and the second rod 223 is adjusted, the fastening sleeve 221 is rotated so that the fastening sleeve 221 is threadedly connected to the first rod 222. Thus, the fastening sleeve 221 can lock the first rod 222 and the second rod 223, preventing the connecting rod 22 from extending or retracting again. Moreover, the length adjustment of the connecting rod 22 is simple.
[0038] In one embodiment, the stop block 4 is provided with a first magnetic attraction part (not shown in the figure) for adsorbing the workpiece 100 to be tested. Understandably, the first magnetic attraction part can be a magnet or similar component disposed on the stop block 4. Since the workpiece 100 to be tested is mostly made of steel, the stop block 4 can magnetically attract and adhere to the workpiece 100 through the first magnetic attraction part. In this embodiment, the design of the first magnetic attraction part improves the stability of the contact between the workpiece 100 to be tested and the stop block 4, and also improves the ease of operation of the inclined plane measuring device for the grinding machine.
[0039] In one embodiment, the worktable 1 is provided with a second magnetic attraction part (not shown in the figure) for adsorbing the stop block 4 and / or the workpiece 100 to be tested. Understandably, the second magnetic attraction part can be a magnet or the like, mounted on the worktable 1. Since the workpiece 100 to be tested and the stop block 4 are mostly made of steel, the stop block 4 and / or the workpiece 100 to be tested can be adsorbed and attached to the worktable 1 by the second magnetic attraction part, improving the stability and ease of mounting the stop block 4 and / or the workpiece 100 to be tested on the worktable 1.
