Abstract
Description
Technical Field
[0001] The invention relates to a benchwork auxiliary tool, and in particular to a tool calibration device with visual deviation correction and a use method thereof. Background Art
[0002] Since automobile parts are mass-produced, the molds used to produce them may be partially worn out during long-term use, which may result in poor fit of the parts, especially the cavity parts of the mold. If there is obvious wear, it is very likely to cause product quality risks. Therefore, it is necessary to repair the worn parts regularly. The repair is generally carried out by the fitter, who measures and observes the fit relationship and then calibrates and repairs the worn parts. For example, after the load-bearing surface is tilted, it can be ground by filing.
[0003] After general benchwork, the plane state of the processed surface can be checked with a level, but due to the complexity of automotive parts, the processed surface of worn parts has multiple bumps, such as sawtooth processed surfaces; considering the limited measurement environment of the level, currently, tools such as contour rulers are generally used to assist in measurement, and after the contour ruler is measured, other measuring tools are required to verify the parameters of the contour ruler, which greatly reduces the efficiency of secondary finishing. Especially for trimming the aperture of the part, the range measurement using the contour ruler will also be limited.
[0004] In the actual operation process, the workpiece is fixed by the tooling to ensure that the reference surface is stable. The fitter then performs auxiliary measurement on the processed surface and then makes corrections. Frequent inspections are required during the finishing process to facilitate timely corrections when processing deviations occur. When correcting through slots or holes, deviations in visual readings often occur, causing the tolerance values of the parts processed by the fitter to frequently approach the upper limit, or even exceed the tolerance range and lead to scrapping. This requires the fitter to calibrate at different angles, resulting in extremely low calibration efficiency. Therefore, it is worth studying how to facilitate the fitter to correct the deviations of some parts. Summary of the invention

[0022] The present invention sets a scale. When the focal point of the laser beam moves a certain distance upward at the edge, if the laser still irradiates the upper end of the workpiece, it is convenient for the staff to determine the degree of correction required. The convex edges of the calibration column and the receiving column are adapted to the concave edges on the push block, thereby preventing the push block from rotating on the calibration column or the receiving column, thereby ensuring that the laser transmitter and the laser receiver correspond to each other and act on the workpiece.

DETAILED DESCRIPTION
[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0032] refer to Figures 1 to 3 As shown, one embodiment of the present invention is a tool calibration device with visual correction, including a support seat, on which a tooling device is installed, and the tooling device is used to clamp the workpiece. During the clamping process, the upper surface of the workpiece may not be kept horizontal due to human factors. Especially in the process of car model benchwork repair, the upper surface may have a certain tilt angle due to hand feel problems. The staff usually use a level ruler for correction to ensure that the upper end surface of the workpiece is relatively horizontal. It should be noted that for workpieces with the upper end surface as the repair surface, because the upper surface may have been worn during the use of the workpiece, secondary processing is required to make the surface relatively flat. In this case, it is generally necessary to use an unworn area that is relatively parallel to the processing surface as a reference.
[0033] The support seat comprises a bottom plate 1 fixed on the workbench and a top plate 2 for installing the tooling equipment, and a connecting platform 3 is arranged between the bottom plate 1 and the top plate 2. The bottom plate 1 and the top plate 2 are parallel to each other, and the two ends of the connecting platform 3 are respectively connected to the bottom plate 1 and the top plate 2, so that an I-shape is formed between the bottom plate 1, the top plate 2 and the connecting platform 3. A guide ring 4 is arranged on the outer side of the connecting platform 3, and the guide ring 4 surrounds the connecting platform 3, fixes the guide ring 4 on the connecting platform 3, and makes the midpoint of the guide ring 4 correspond to the midpoint of the connecting platform 3. A check column 5 and a receiving column 6 are arranged on the guide ring 4, wherein the spacing between the check column 5 and the receiving column 6 is greater than the distance between the two ends of the top plate 2, so that the check column 5 and the receiving column 6 are not blocked by the top plate 2 when they move on the guide ring 4.
[0034] In order to better maintain the distance between the verification column 5 and the receiving column 6 and ensure that the verification column 5 corresponds to the receiving column 6, the positions of the verification column 5 and the receiving column 6 are opposite, and the verification column 5 and the receiving column 6 are connected by a first connecting ring 7. The verification column 5 and the receiving column 6 are used to move synchronously on the guide ring 4.
[0035] Among them, the distance between the verification column 5 and the receiving column 6 is the diameter of the guide ring 4 at both ends. The first connecting ring 7 is an existing alloy structure. The center of the first connecting ring 7 overlaps with the center of the guide ring 4, and the two ends of the first connecting ring 7 are respectively connected to the verification column 5 and the receiving column 6. The verification column 5 and the receiving column 6 are rigidly connected to make the distance between the verification column 5 and the receiving column 6 constant, so that when the verification column 5 and the receiving column 6 move on the guide ring 4, the positions of the verification column 5 and the receiving column 6 remain relative.
[0036] The above-mentioned verification column 5 and the receiving column 6 are both sleeved with a push block 8 , and a second connecting ring 9 is provided between the above-mentioned push blocks 8 . The above-mentioned second connecting ring 9 is used to drive the push block 8 to move synchronously on the verification column 5 and the receiving column 6 .
[0037] There are two push blocks 8, which are respectively located on the verification column 5 and the receiving column 6. The two push blocks 8 are connected by a second connecting ring 9, so that the push blocks 8 are rigidly connected, so that the push block 8 of the verification column 5 and the push block 8 of the receiving column 6 can move up and down synchronously at the same horizontal height.
[0038] The push block 8 of the calibration column 5 is provided with a laser transmitter 10, and the push block 8 of the receiving column 6 is provided with a laser receiver 11. The laser receiver 11 is opposite to the laser transmitter 10, and the laser transmitter 10 is used to continuously transmit a visible laser beam to the laser receiver 11. The transmitting end of the laser transmitter 10 corresponds to the receiving end of the laser receiver 11, and the visible laser beam is used to contact the workpiece to assist in determining the deviation state of the workpiece.
[0039] The laser transmitter 10 and the laser receiver 11 are both existing products. The laser transmitter 10 can be an existing infrared transmitter, and the laser receiver 11 can be an existing infrared receiver. The workpiece is fixed on the tooling and the laser transmitter 10 is used to emit a visible infrared beam to the workpiece, so that the workpiece is leveled by the infrared beam. Secondly, for the through grooves or through holes of the workpiece, considering that the use of the ruler is not convenient enough and the visual reading is prone to deviation, the infrared beam can also be used through the visible beam to confirm whether the through opening is deformed, which has a good auxiliary effect to a certain extent.
[0040] Among them, the function of the laser receiver 11 is to receive the visible laser beam sent by the laser transmitter 10. The visible laser beam is collected by the laser receiver 11 and the optical signal is converted into a changing electrical signal, and transmitted to the controller, which turns on the external warning light of the controller to express that the laser receiver 11 has collected the visible laser beam emitted by the laser transmitter 10.
[0041] It is worth noting that, when necessary, laser sensors arranged in a row can also be used on one side of the laser emitter 10. The laser emitter 10 projects a laser beam onto the surface to be measured by laser triangulation measurement, and uses a photosensitive array to receive the diffuse reflected light of the surface to be measured and convert it into an electrical signal, thereby obtaining geometric information of the surface to be measured; that is, when the laser beam is irradiated on the workpiece to form a reflection, its laser sensor tests the workpiece by testing the angle of the laser beam reflected back to the reader, and uses the signal for mutual difference to determine the surface state.
[0042] Based on the above embodiments, reference Figure 1 As shown, another embodiment of the present invention is that the first connecting ring 7 and the second connecting ring 9 are parallel to each other, so as to help the laser transmitter 10 and the laser receiver 11 to be at the same level. The central axis of the first connecting ring 7 overlaps with the central axis of the guide ring 4, so that the first connecting ring 7 and the second connecting ring 9 do not interfere with each other during operation.
[0043] The central axis of the second connecting ring 9 overlaps with the central axis of the first connecting ring 7, so that no matter where the first connecting ring 7 rotates, the center point of the second connecting ring 9 remains relative to the first connecting ring 7, so that the movement of the verification column 5 and the receiving column 6 will not hinder the movement of the push block 8.
[0044] The distance between the verification column 5 and the receiving column 6 is relatively constant, and the push block 8 of the verification column 5 is opposite to the push block 8 of the receiving column 6. This is conducive to maintaining the corresponding relationship between the laser receiver 11 and the laser transmitter 10.
[0045] It is worth emphasizing that the laser emitted by the laser transmitter 10 is visible light, and its light beam is strong light; in order to avoid the influence of other external light beams, the laser receiver 11 needs to collect the strong light before giving corresponding feedback.
[0046] In order to more intuitively determine the height of the laser receiver 11 and the laser transmitter 10, further, the above-mentioned verification column 5 and the receiving column 6 are provided with scale marks. Since the starting point of the height is generally the edge of the workpiece, if the height of the push block 8 is raised at this time, the light beam will leave the edge of the workpiece but be blocked by the workpiece. Then, there is a slope in the penetrating part. It is necessary to determine whether there is a deviation based on the original design drawing so as to correct the deviation in time.
[0047] Since the corresponding relationship between the laser receiver 11 and the laser transmitter 10 is still required to be maintained when the push block 8 moves upward, the push block 8 cannot shake easily in principle. The push block 8 is provided with a concave edge, and the outer walls of the verification column 5 and the receiving column 6 are provided with a convex edge 12 corresponding to the concave edge.
[0048] By utilizing the corresponding relationship between the convex ridges 12 and the concave ridges, the push block 8 will not shake easily on the verification column 5 and the receiving column 6 .
[0049] Based on the above embodiment, another embodiment of the present invention is that the diameter of the connecting platform 3 is smaller than the diameter of the guide rail ring 4, so that the connecting platform 3 will not block the guide rail ring 4, and a support beam 13 is provided between the connecting platform 3 and the guide rail ring 4.
[0050] There are multiple support beams 13 , one end of each support beam 13 is connected to the side wall of the guide rail ring 4 , and the other end of each support beam 13 is connected to the side wall of the connecting platform 3 .
[0051] The lower ends of the above-mentioned verification column 5 and the receiving column 6 are both provided with a slider 14, and the above-mentioned slider 14 is sleeved on the guide ring 4, wherein the inner diameter of the slider 14 is adapted to the outer diameter of the guide ring 4, and the above-mentioned verification column 5 and the receiving column 6 are both moved on the guide ring 4 through the slider 14.
[0052] The side wall of the slider 14 is provided with an opening corresponding to the support beam 13 , and the opening on the slider 13 can prevent the support beam 13 from restricting the movement of the slider 14 .
[0053] In terms of stability, both the verification column 5 and the receiving column 6 are provided with a slider 14. Since the slider 14 is rigidly connected, the slider 14 on the verification column 5 and the slider 14 on the receiving column 6 are positioned relative to each other, the openings of the two sliders 14 are relative to each other, and the two sliders 14 are mutually constrained on the guide ring 4, which is conducive to maintaining the stability of the slider 14 on the guide ring 4.
[0054] Further, in order to reduce the friction coefficient between the slider 14 and the guide ring 4, refer to Figure 3 As shown, the inner wall of the slider 14 is provided with a ball groove, and a ball 15 is arranged in the ball groove, and the outer surface of the guide ring 4 is provided with a groove corresponding to the ball 15. The groove on the guide ring 4 is in contact with the ball 15 on the slider 14, thereby reducing the friction coefficient between the slider 14 and the guide ring 4.
[0055] The groove of the guide ring 4 surrounds the guide ring 4, and the ball groove on the inner wall of the slider 14 is an arc-shaped groove. The ball 15 is placed in the ball groove. The ball 15 is constrained by the ball groove, which helps to prevent the ball 15 from falling off the groove of the guide ring 4.
[0056] Based on the above embodiments, reference Figure 1 , Figure 4 and Figure 5 As shown, another embodiment of the present invention is that the above-mentioned tooling equipment includes two relatively arranged mounting plates 16, wherein the mounting plates 16 are used as support units, and the workpiece is mainly used to be installed between the two mounting plates 16, and the above-mentioned mounting plates 16 are vertically installed on the top plate 2. Since the laser receiver 11 and the laser transmitter 10 can surround the top plate 2, when the mounting plates 16 are fixed on the top plate 2, the laser receiver 11 and the laser transmitter 10 can cover the workpiece between the mounting plates 16.
[0057] In order to better fix the workpiece, a mounting tube 17 is provided on the mounting plate 16. The mounting tube 17 is parallel to the guide rail ring 4. A nut seat 18 is provided at the front end of the mounting tube 17. A screw rod 19 is installed on the nut seat 18. The nut seat 18 and the screw rod 19 are threadedly matched. By rotating the nut seat 18, the screw rod 19 moves back and forth in the mounting tube 17.
[0058] In order to better contact the workpiece, a resistance plate 20 is provided at the front end of the screw rod 19, and the resistance plates 20 on the two mounting plates 16 are arranged relatively, wherein the resistance plate 20 moves with the screw rod 19, and the screw rod 19 is used to move on the nut seat 18 and push the resistance plate 20 to contact the workpiece.
[0059] For further reference, Figure 4 and Figure 5 As shown, in order to enable the tooling equipment to adjust the angle of the workpiece after holding the workpiece, the above-mentioned mounting cylinder 17 is hollow, and the end of the above-mentioned screw rod 19 is placed in the mounting cylinder 17. It is worth noting that the interior of the mounting cylinder 17 is hollow, and the inner cavity diameter of the mounting cylinder 17 is consistent with the outer diameter of the screw rod 19, which is beneficial to the stability of the screw rod 19 in the mounting cylinder 17.
[0060] The mounting plate 16 is provided with a bearing 21, wherein the inner ring of the bearing 21 is longer than the outer ring, and the outer ring rotates relative to the inner ring. The inner ring of the bearing 21 is fixed on the mounting plate 16, wherein the mounting plate 16 is provided with a mounting hole corresponding to the inner ring of the bearing 21, and the bearing 21 can be mounted on the inner ring by welding. The mounting cylinder 17 is fixed on the outer ring of the bearing 21, and the rear end of the mounting cylinder 17 is provided with a mounting hole corresponding to the outer ring of the bearing 21, and the portion of the outer ring of the bearing 21 that exceeds the inner ring is welded in the mounting hole of the mounting cylinder 17.
[0061] It is worth noting that the inner ring hole size of the bearing 21 is larger than the diameter of the screw 19 , so that the screw 19 can penetrate deeper into the bearing 21 when it moves backward to a large extent, thereby preventing the screw 19 from colliding with the mounting tube 17 .
[0062] In order to ensure that the workpiece can be effectively fixed after the angle is adjusted, a limit plate 22 is provided on the outer wall of the mounting tube 17. The limit plate 22 contacts the mounting plate 16. A limit hole is provided on the limit plate 22. The mounting plate 16 is provided with a screw hole corresponding to the limit hole. Bolts 23 are inserted into the limit hole and the screw hole to lock the limit plate 22 on the mounting plate 16.
[0063] During operation, the mounting tube 17 can be rotated relative to the mounting plate 16 by releasing the bolt 23 on the limit plate 22. When the workpiece has been adjusted to the corresponding angle, the adjustment angle is generally 15, 30, 45, 60, 75, 90 degrees, etc. At this time, the screw hole of the mounting tube 17 corresponds to the limit hole of the mounting plate 16. By inserting the bolt 23 into the limit hole and the screw hole, the mounting tube 17 and the mounting plate 16 are kept in a relatively fixed state, so that the workpiece can be effectively fixed after the angle is adjusted.
[0064] Based on the above embodiment, another embodiment of the present invention is a method for using a tool calibration device, using the tool calibration device of the above embodiment, including the following operating steps:
[0065] Step A, laser position calibration, start the laser transmitter 10, the laser transmitter 10 continuously emits a visible laser beam to the laser receiver 11, and verifies the corresponding state of the laser transmitter 10 and the laser receiver 11. After the laser receiver 11 collects the laser beam, the position calibration is completed. This step is mainly used to ensure whether the laser transmitter 10 and the laser receiver 11 are in a corresponding relationship in the initial state, and to ensure whether the laser transmitter 10 and the laser receiver 11 can work normally. If the correspondence between the laser transmitter 10 and the laser receiver 11 cannot be guaranteed, the relative position and orientation of the laser transmitter 10 and the laser receiver 11 need to be adjusted.
[0066] Step B, laser upward calibration, after completing the laser position calibration, ensure that the laser emitter 10 and the laser receiver 11 are in normal working state, pull the push block 8 up and down through the second connecting ring 9, verify the corresponding state of the laser emitter 10 and the laser receiver 11 when moving up and down, and complete the laser upward calibration after the laser receiver 11 collects the laser beam. This step can verify whether the push blocks 8 work synchronously and whether there is a deviation between the two push blocks 8.
[0067] Generally speaking, when the push block 8 moves upward synchronously, but the laser emitter 10 and the laser receiver 11 cannot correspond, and the movement of the push block 8 is blocked, it indicates that the push block 8 may be out of synchronization, the push block 8 may be partially damaged, or the verification column 5 and the receiving column 6 are not parallel.
[0068] Step C, laser orbit calibration, after completing the laser position calibration, pull the calibration column 5 and the receiving column 6 to rotate synchronously on the guide ring 4 through the first connecting ring 7, and verify the corresponding state of the laser transmitter 10 and the laser receiver 11 when they move around the tooling equipment. After the laser receiver 11 collects the laser beam, the laser orbit calibration is completed. Similar to step B, the first connecting ring 7 pulls the calibration column 5 and the receiving column 6 to rotate on the guide ring 4, mainly to determine whether the laser transmitter 10 and the laser receiver 11 are stable during the rotation around the workpiece.
[0069] Step D, workpiece installation correction, fix the workpiece on the tooling equipment, adjust the relative positions of the verification column 5 and the receiving column 6 through the first connecting ring 7, so that the visible laser beam emitted by the laser transmitter 10 avoids the obstruction of the tooling equipment and irradiates the workpiece, and then pull the push block 8 upward through the second connecting ring 9 to make the visible laser beam to be emitted by the laser receiver 11 gradually separate from the workpiece processing surface. If the visible laser beam separates from the processing surface and is collected by the laser receiver 11, the workpiece processing surface is not offset. Otherwise, adjust the posture of the workpiece on the tooling equipment, and repeat step D until the visible laser beam separates from the processing surface and is collected by the laser receiver 11.
[0070] In the actual workpiece installation process, the general fitter is installed manually, and its reference surface is generally in contact with the abutment plate 20. Taking into account the deviation of manual installation, the workpiece may be tilted during the support of the abutment plate 20, and this part of the tilt has a certain impact on the later assembly and workpiece finishing. For areas that may affect the workpiece processing, such as the demolding groove in the cavity, it is necessary to grind; first, it is necessary to determine whether the drilling path corresponds to the central axis of the original hole, then the workpiece processing surface needs to be placed horizontally, and then the horizontal calibration is performed using a level ruler, and then the tooling equipment rotates the workpiece 90 degrees, adjusts the position of the calibration column 5 and the receiving column 6, and uses the push block 8 to make the laser receiver 11 and the laser transmitter 10 correspond to the processing hole of the workpiece, and irradiates the laser beam through the edges of the workpiece hole on both sides to ensure that when the push block 8 is at the same height, the penetration of the two ends of the processing hole of the workpiece is detected to avoid large deviations at both ends of the processing hole, which is beneficial to prevent the positions of the two ends of the processing hole from exceeding the tolerance range after hole expansion.
