Description

Technical Field

[0001] The present invention relates to the technical field of hemisphere detection, and in particular to a V-shaped ball detection method and a V-shaped ball detection device. Background Art

[0002] V-shaped balls are not common in production and life. They are mainly used in complex engineering machinery such as valves. Since the angle between the two sectors of the V-shaped ball is less than 180 degrees, the radius or diameter of the V-shaped ball cannot be obtained by intuitive measurement, and the distance from the center of the ball to the end plane cannot be measured intuitively. The current industry also lacks attention to the measurement method of the diameter of this type of sphere. However, the radius and end face dimensions of the processed sphere are very critical during assembly, which directly affects the subsequent assembly and use of the valve.

[0003] Since the V-shaped ball has only a part of the spherical surface, conventional measuring tools cannot directly measure the spherical radius and the distance from the two end surface planes to the center of the ball.

[0004] Therefore, a V-shaped ball detection method and device are still needed to solve the above problems. Summary of the Invention

[0005] The present invention provides a V-shaped ball detection method and device for solving the above problems.

[0006] The purpose of the present invention is achieved by the following technical solutions:

[0007] A V-shaped ball detection method is used to detect the radius of a hemisphere in a hemisphere assembly. The hemisphere assembly includes a core shaft and a hemisphere. The two sides of the hemisphere are truncated spherical. The axis of the end hole passes through the center of the hemisphere. The core shaft passes through the end hole of the hemisphere. When combined together, the hemisphere assembly comprises:

[0008] Determine the coordinate zero point of the center of the hemisphere to be measured in the X and Y directions using a process standard ball, where the process standard ball is similar in shape to the hemisphere assembly but simpler in shape than the hemisphere assembly;

[0009] Use the core axis of the V-shaped ball to be measured to determine the coordinate zero point of the center of the hemisphere to be measured in the Z direction;

[0010] Remove the process standard ball and replace it with the hemisphere assembly to be measured. Drive the hemisphere assembly to move in the Y direction, and determine the coordinate zero point position of the center of the hemisphere to be measured in the Y direction through the same abutment readings of the two dial indicators;

[0011] By moving the probe end of the depth gauge to abut the end face of the hemisphere, the reading at this time is the distance from the end face to the center of the sphere;

[0012] When the reading of a dial indicator on the height gauge is the maximum, the height at this time is determined to be the radius of the sphere.

[0013] And drive the hemisphere assembly to move in the Y direction so that the contact of one of the dial indicator contacts the upper surface of the hemisphere. When the dial indicator shows the largest reading on the sphere, lift the height gauge upward in the Z direction, then drop it to contact the sphere again. When the percentage reading is 0, record the height gauge reading at this time as the radius of the sphere.

[0014] In one embodiment, determining the coordinate zero point of the center of the hemisphere to be measured in the X and Y directions includes:

[0015] Calibrate the two dial indicators on the V-type table surface until the two percentage indications are consistent;

[0016] Place the process standard ball on the V-shaped seat, place the contacts of the two dial indicators against the outer circle of the end shaft, and adjust the X direction of the two dial indicators until the readings of the two dial indicators appear to be the maximum value to confirm that the axis of the end shaft is located vertically above. Fix the X-direction slide. At this time, the center point between the two dial indicators is the reference point in the X and Y directions (i.e., the zero point of the X and Y coordinates);

[0017] Place the contacts of the two dial indicators against the outer circle of the spherical surface of the process standard ball, and then adjust the Y-direction slide below the process standard ball until the readings of the two dial indicators are the same. At this time, it is determined that the center of the process standard ball coincides with the zero position of the Y direction, that is, the center of the ball is at the zero position of the coordinates X and Y;

[0018] Push the depth gauge until the probe end contacts the end face of the process standard ball-end shaft and then return the depth gauge reading to zero;

[0019] Remove the process standard ball assembly, move the depth gauge probe end to the distance L0 and then reset the depth gauge indication to zero. Then move the depth gauge probe position to the starting safety position. L0 is the distance value from the end of the process standard ball end shaft to the center of the ball.

[0020] In one embodiment, determining the reference point of the center of the hemisphere to be measured in the Z direction (i.e., the Z-direction coordinate zero point) includes:

[0021] Place the core shaft of the V-shaped ball product on the V-shaped seat, move the slides under the two dial indicators in the X direction until the readings of the two dial indicators appear to be the maximum, and make sure that the axis of the core shaft is located vertically above. Fix the X-axis slide and return the scales of the two dial indicators to zero at the same time.

[0022] Return the height gauge to zero, remove the core shaft, move the height gauge vertically down to a height of R0, and then return the height gauge to zero. At this time, the position of the dial indicator probe is the reference point of the center of the sphere in the Z direction (Z-axis coordinate zero point), and R0 is the radius of the core shaft.

[0023] In one embodiment, moving the measuring end of the depth gauge to contact the end surface of the hemisphere and obtaining the reading at that time as the distance from the end surface to the center of the sphere includes:

[0024] Insert the core shaft into the two end holes of the V-shaped ball product to be measured to form a V-shaped ball assembly, and place the core shaft of the V-shaped ball assembly on the V-shaped groove of the V-shaped frame. Drive the V-shaped ball assembly to move in the Y direction and observe until the two dial indicators have the same abutment readings. At this time, the center of the V-shaped ball to be measured is at the reference point in the Y direction (the zero point of the Y coordinate).

[0025] Push the probe end of the depth gauge against the end face of the hemisphere and record the displayed depth - L at this time. The L value at this time is the distance from the center of the sphere to the end face of the V-shaped hemisphere.

[0026] In one embodiment, determining the height as the spherical radius when the reading of a dial indicator of the height gauge is the maximum includes:

[0027] Move the position of the V-type seat slide and use the contact of one of the dial indicator to touch the upper surface of the hemisphere. When the percentage indication value is the largest, it is determined as the highest point. Then lift the dial indicator at the highest point and drop it again so that the dial indicator reading is 0. The reading on the height scale is the spherical radius R.

[0028] In one embodiment, the process of removing the process standard ball and replacing the hemisphere assembly to be tested further includes the following steps:

[0029] Insert the mandrel into the hemisphere and quickly determine the position of the V-shaped hemisphere using the positioning rod fixed to the end of the test table.

[0033] A horizontal module, comprising a V-shaped seat and a slide rail connected to the bottom of the V-shaped seat, and moving along the Y direction, wherein the X-direction, the Z-direction and the Y direction are perpendicular to each other;

[0034] A depth gauge is provided on a workbench, and a movable end of the depth gauge is consistent with a moving direction of the V-shaped seat.

[0035] In one embodiment, a V-shaped groove is formed on the top of the V-shaped seat, and both sides of the V-shaped groove are horizontal surfaces.

[0036] In one embodiment, the planar moving module further includes a first screw rod connected to the first hand wheel, both ends of the first screw rod are rotatably connected to the side plates of the sliding seat, and the middle section is threadedly connected to the sliding seat.

[0040] To measure the radius of a hemisphere and the distance from its center to the end face, a process standard ball is used to determine the Y-axis reference of the hemisphere's center.

DETAILED DESCRIPTION

[0048] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the drawings represent identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0049] The words expressing positions and directions described in the present invention are all explained with reference to the accompanying drawings as examples, but can be modified as needed, and all such modifications are within the scope of protection of the present invention.

[0050] Reference Figure 1-6 In a first aspect, the present invention provides a V-shaped ball detection method for detecting the diameter of a hemisphere in a hemisphere assembly. The hemisphere assembly includes a core shaft and a hemisphere, and the two sides of the hemisphere are truncated. The process standard ball and the hemisphere assembly are similar in shape, and the axis of the end hole passes through the center of the hemisphere. The core shaft passes through the end hole of the hemisphere. When combined, they form the hemisphere assembly. The detection method includes:

[0051] The coordinate zero point of the center of the hemisphere to be measured in the X and Y directions is determined by the process standard ball. The process standard ball is similar in shape to the hemisphere assembly, but is simpler than the hemisphere assembly. Figure 6 .

[0052] Determining the reference point of the center of the hemisphere to be measured in the X and Y directions, that is, the coordinate zero point in the X and Y directions, includes:

[0053] Calibrate the two dial indicators on the V-type table plane until the two percentage indications are consistent; this step is to correct the readings of the two dial indicators to avoid affecting the subsequent positioning process.

[0054] Place the process standard ball on the V-shaped seat 31, make the contacts of the two dial indicators 25 touch the outer circle of the end shaft, adjust the X direction of the two dial indicators 25 until the readings of the two dial indicators 25 reach the maximum value, confirm that the axis of the end shaft is in the vertical direction, fix the X-direction plane moving module 2, and at this time the center point between the two dial indicators is the coordinate zero point in the X and Y directions.

[0055] Place the contacts of the two dial indicators 25 against the outer circumference of the spherical surface of the process standard ball, and then adjust the horizontal module slide 3 in the Y direction below the process standard ball until the readings of the two dial indicators 25 are the same. At this time, it is determined that the center of the process standard ball coincides with the zero position in the Y direction, that is, the center of the ball is at the zero position of the coordinates X and Y;

[0056] Push the probe end of the depth gauge 4 to abut against the end face of the process standard ball-end shaft, and then return the indication of the depth gauge 4 to zero;

[0057] Remove the process standard ball assembly, move the probe end of the depth gauge 4 to the distance L0 and then return the depth gauge 4 reading to zero. Since the depth gauge 4 is fixed in position and does not change, the zero position of the probe of the depth gauge 4 is the zero point of the Y direction at this time. Then move the probe position of the depth gauge 4 to the starting safety position. L0 is the distance value from the end of the process standard ball end shaft to the center of the ball.

[0058] And determine the coordinate zero point of the center of the hemisphere to be measured in the Z direction:

[0059] Determining the coordinate zero point of the center of the hemisphere to be measured in the Z direction includes:

[0060] Place the core shaft of the V-shaped ball product on the V-shaped seat 31, and move the moving module 2 under the two dial indicators 25 in the X direction until the readings of the two dial indicators 25 appear to be the maximum value, confirming that the axis of the core shaft is located vertically above, fix the X-axis slide, and return the scales of the two dial indicators 25 to zero.

[0061] Return the height gauge 24 to zero, remove the core shaft, move the height gauge 24 vertically down to a height of R0, and then return the height gauge 24 to zero. At this time, the position of the dial indicator 25 probe is the coordinate zero point of the center of the sphere in the Z direction, and R0 is the radius of the core shaft.

[0062] By moving the measuring end of the depth gauge against the end face of the hemisphere, the reading at this time is obtained as the distance from the end face to the center of the sphere, including:

[0063] Insert the core shaft into the two end holes of the V-shaped ball product to be measured (V-shaped ball assembly 5), and place the core shaft of the V-shaped ball assembly 5 on the V-mouth of the V-shaped frame. Drive the V-shaped ball assembly 5 to move in the Y direction and observe until the two dial indicators 25 have the same abutment readings. At this time, the center of the V-shaped ball to be measured is at the coordinate zero point in the Y direction.

[0064] Push the probe end of the depth gauge against the end face of the hemisphere and record the displayed depth - L at this time. The L value at this time is the distance from the center of the sphere to the end face of the V-shaped hemisphere.

[0065] When the reading of a dial indicator 25 of the height gauge 24 is the maximum, determining the height at this time as the spherical radius includes:

[0066] Move the V-shaped seat 31 to the position of the horizontal module slide 3, and use the contact of one of the dial indicator 25 to touch the upper surface of the hemisphere 5. When the dial indicator 25 shows the maximum value, it is determined as the highest point. Then lift the dial indicator 25 at the highest point and drop it again until the reading of the dial indicator 25 is 0. The reading on the height gauge 24 is the spherical radius R of the actual hemisphere product.

[0067] In one embodiment, the process of removing the process standard ball and replacing the hemisphere assembly to be tested further includes the following steps:

[0068] Insert the mandrel into hemisphere 5 and quickly determine the position of the V-shaped hemisphere using the positioning rod fixed to the end of the inspection table. It is important to note that when inserting and fixing the mandrel into the hemisphere, the mandrel diameter must closely match the end surface of the hemisphere product, with the clearance controlled between 0.01-0.02mm.

[0069] The method of the present invention uses multiple adjustments to zero the sphere's center in order to obtain a reference zero point in both directions. All subsequent measurements must be based on the previously determined reference zero point. This simplifies the operator's calculations and logic, improving efficiency when measuring the diameter of a difficult-to-measure hemisphere.

[0070] The second aspect of the present invention further provides a V-shaped ball detection device, referring to Figure 1 As shown, it is used to detect the radius of a hemisphere and the distance from the center of the sphere to the end plane.

This facilitates precise adjustment of the two dial indicators 25, reduces data errors caused by direct movement, and facilitates operator operation.

[0077] In one embodiment, the horizontal module includes a second screw rod 33, with both ends pivotally connected to the side plates of the slide rail 32, a middle section threadedly connected to the bottom of the V-shaped seat 31, and one end of the second screw rod 33 extending from the side plate of the slide rail 32 to connect to a second handwheel 34. Manually driving the screw rod allows for precise adjustment of the spindle position on the slide seat 21, facilitating subsequent data measurement and collection while reducing errors caused by direct manipulation.

[0078] A connecting plate 35 is provided on one side of the workbench 1 , and the connecting plate 35 is perpendicular to the workbench 1 . The depth gauge 4 is connected to the workbench 1 , and the movable end thereof can move in a horizontal direction.

[0079] The above device allows workers to use a simple and controllable device to perform various complex detection operations on the hemisphere, has low usage cost and reproducibility, and is convenient for employees to use and operate quickly.
