Description

Installation hole site evaluation detection tool for detecting object

Technical Field

The present disclosure relates generally to the field of installation site assessment detection. More particularly, the present disclosure relates to a mounting hole site evaluation detection appliance for detecting an object.

Background

In production practice, parts such as screws are often used to pass through mounting holes to complete the connection and assembly of the components. Proper machining of the mounting holes is very important. Errors in position or excessive errors can lead to assembly failure and rework, resulting in significant economic loss.

In order to find possible position errors of the mounting hole in time, spot check measurement is required after the component is finished. The currently common measurement technique is a three-coordinate system. The three-coordinate system is also called a three-coordinate measuring machine (Coordinate Measuring Machine, abbreviated as CMM), which is an instrument with measuring capability for calculating various geometric shapes, sizes and the like in a three-dimensional measurable space range according to position point data returned by a detection part of a measuring head system. When the three-coordinate system is used for evaluating and detecting the positions of the mounting hole sites, the mounting hole sites are required to be detected one by one, and the working speed cannot meet the actual requirement of mass production.

Referring now to the drawings, FIG. 1 illustrates one example of a mounting hole site evaluation test platform. The installation hole site evaluation and detection platform comprises an installation hole site evaluation and detection appliance 1 and lifting support equipment 2. The installation site evaluation detection appliance 1 is mounted above the lifting support device 2, for example in a removable manner above the lifting support device 2. The mounting hole position evaluation detecting tool 1 is used to evaluate and detect whether or not the processing position (including the horizontal direction and/or the vertical direction) of the mounting hole position of the detection object is correct. The detection object may be, for example, a body-in-white of a vehicle, or, for example, a front axle and/or a rear axle of a vehicle. The lifting support device 2 is used for bearing and moving the installation site evaluation and detection appliance 1 and lifting the same to a proper height.

As shown in fig. 2, the mounting hole site evaluation detecting instrument 1 includes a main body 15, at least two positioning

pins

11, 12 provided on the main body 15, and a plurality of matching hole sites 21. The at least two positioning

pins

11, 12 are configured to be inserted into respective positioning holes of the detection object. The positions of the plurality of matching hole sites 21 (including positions in the horizontal direction and/or in the vertical direction) are set to correspond to mounting hole sites of the detection object to be evaluated and detected.

The main body 15 of the mounting hole position evaluation and detection tool 1 includes a middle support portion 151, an extension portion 152, and one or more plate members 153. The intermediate support 151 is adapted to rest on a support table 250 (described in more detail below) of the lifting support apparatus 2. The lower surface of the intermediate support portion 151 is provided with a lower protruding frame (not shown). When the intermediate support 151 is placed on the support table 250 of the lifting support apparatus 2, the lower frame encloses an upper frame 252 (described in detail below) on the support table 250. The extension 152 extends outward from the intermediate support 151 for supporting the plate 153. The extension 152 may be in a frame structure, thereby facilitating a reduction in its own weight and an improvement in economy. Each plate 153 is fixed to the protruding portion 152, and is provided with at least one of a positioning pin and a mounting hole. In some embodiments, plate 153 is rectangular in shape and is secured to extension 152, for example, by welding or a threaded connection.

In some embodiments, the upper surface of the main body 15 of the mounting hole site evaluation detecting instrument 1 including the intermediate support portion 151, the protruding portion 152, and the plate 153 has the same shape as the entire upper surface of the main body 15 of the detecting object on which the mounting hole site is formed, so as to achieve complete fitting of the positioning pins 11, 12, the matching hole site 21, and the mounting hole site of the detecting object of the mounting hole site evaluation detecting instrument 1. In other embodiments, the overall shape of the upper surface of the main body 15 of the mounting hole site evaluation detecting instrument 1 and the lower surface of the detecting object on which the mounting hole site is formed may not be identical, but only the positions of the positioning pins 11, 12, the matching hole site 21 are fitted with the mounting hole site.

In some embodiments, the installation site evaluation detection tool 1 includes two locating pins: a first locating pin 11 and a second locating pin 12. In some embodiments, the positions of the first positioning pin 11 and the second positioning pin 12 are set according to two positioning holes in the detection object that are far apart, so that positioning accuracy is improved to some extent. In some embodiments, the first locating pin 11 is located on one side of the installation site evaluation detection instrument 1 and the second locating pin 12 is located on the opposite side of the installation site evaluation detection instrument 1. In some embodiments, the first and second locating pins 11, 12 are disposed generally symmetrically about the longitudinal axis of the installation site evaluation detection instrument 1, as shown in fig. 2.

As shown in fig. 3A, 3B and 4, each of the positioning pins 11, 12 includes a sleeve 13, and a movable pin body 14 provided in the sleeve 13. The sleeve 13 is hollow and substantially cylindrical. The positioning pins 11, 12 are mounted by their sleeves 13 on the plate 153 of the mounting hole site evaluation and detection instrument 1. The sleeve 13 extends through the plate 153 and a radial flange on the upper part of the sleeve 13 abuts against the upper surface of the plate 153. The pin body 14 includes a top tapered section 111, a middle cylindrical section 112, and a lower cylindrical section 116. The top tapered section 111 has a cross-sectional diameter that gradually increases from top to bottom to facilitate insertion into a locating hole of a test object. The cross-sectional diameter of the middle cylindrical section 112 is constant or varies little in magnitude. The lower diameter of the middle cylindrical section 112 suddenly decreases to form a lower cylindrical section 116. A step 115 is formed between the middle cylindrical section 112 and the lower cylindrical section 116. The stepped portion 115 is provided inside the sleeve 13. A through hole 117 is provided in the bottom wall of the sleeve 13, the diameter of the through hole 117 being slightly larger than the diameter of the lower cylindrical section 116 but smaller than the diameter of the middle cylindrical section 112, so that the lower cylindrical section 116 can pass smoothly through the through hole 117, while the middle cylindrical section 112 is blocked by the bottom wall and cannot pass through, so that the stepped portion 115 abuts against the bottom wall.

In some embodiments, a resilient member (not shown) is provided in the sleeve 13. The elastic member is provided between the bottom wall of the sleeve 13 and the stepped portion 115 of the pin body 14. The elastic member allows the pin body 14 to protrude sufficiently upward from the sleeve 13 without the pin body 14 being subjected to downward external force. When the pin 14 is subjected to a downward external force, the pin 14 moves downward, and the stepped portion 115 compresses the elastic member until the pin 14 is completely retracted into the sleeve 13. Preferably, the elastic member is a spring.

As shown in fig. 5-7, the lifting support device 2 comprises a base 23 and a double-powered lifting means 24, and the double-powered lifting means 24 is mounted above the base 23. The base 23 is used for supporting the double-power lifting device 24, and the double-power lifting device 24 is used for supporting and lifting the installation hole site evaluation and detection appliance 1.

In some embodiments, the base 23 includes a collapsible grip 231, the grip 231 for a user to hold to move the base 23. Preferably, the handle 231 includes two handles, which are respectively provided at both sides of the base 23. The pull 231 has an extended position (as shown in fig. 5) and a collapsed position (not shown). The handle 231 is switched about the root axis of rotation between an extended position and a collapsed position. The top of the base 23 is provided with a pair of pivoting portions 232 spaced apart a certain distance L in the lateral direction, and a pair of longitudinal rails 233 spaced apart the same distance L in the lateral direction. The pair of pivot portions 232 and the pair of longitudinal rails 233 are spaced apart in the longitudinal direction and are used to connect the X-shaped mechanism 210 of the dual power lift device 24 (described in more detail below). In some embodiments, a plurality of universal wheels (not shown) are provided at the bottom of the base 23 to facilitate movement of the lifting support device 2.

The dual power lift device 24 includes a support table 250 and an X-shaped mechanism 210. The support table 250 is used for placing the mounting hole site evaluation and detection tool 1, and the X-shaped mechanism 210 drives the support table 250 to reciprocate up and down in the vertical direction by a driving mechanism. The drive mechanism may comprise a hydraulic drive mechanism and/or a manual drive mechanism. The double-power lifting device is independently operated or jointly matched by a hydraulic driving mechanism and a manual driving mechanism so as to finish lifting operation.

The support 250 has a substantially plate shape. An upper protruding frame 252 is provided on top of the support table 250, and a plurality of planar ball bearings 253 are provided at intervals on top of the upper protruding frame 252. When the intermediate support portion 151 of the mounting hole position estimation detection tool 1 is placed on the support table 250 of the lifting support apparatus 2, the plurality of planar ball bearings 253 support the lower surface of the intermediate support portion 151 of the mounting hole position estimation detection tool 1. The lower convex frame (not shown) of the intermediate support 151 surrounds the upper convex frame 252 on the support table 250, thereby defining the horizontal movement range of the installation site evaluation and detection tool 1. The lower protruding frame has a smaller thickness than the upper protruding frame 252 so that the lower surface of the lower protruding frame of the middle supporting portion 151 does not contact with the upper surface of the supporting table 250 to generate friction. The bottom of the support table 250 is provided with a pair of pivoting portions 220 spaced apart by a distance L in the lateral direction, and a pair of upper slide grooves 217 spaced apart by a distance L in the lateral direction. The pair of pivot portions 220 and the pair of upper slide grooves 217 are spaced apart in the longitudinal direction and serve to connect the X-shaped mechanism 210.

The X-shaped mechanism 210 is configured to perform a scissor-type motion about its own pivot point. The X-shaped mechanism 210 includes two sets of X-shaped arms 216. The two sets of X-shaped arms 216 are spaced apart from each other by a distance L in the lateral direction and are parallel and symmetrically arranged about a plane of symmetry of the lifting support device 2 to cooperatively lift the support table 250. Each set of X-shaped arms 216 has two arms and the two arms are pivotally connected together at a neutral position or pivot point so as to be configured for scissor-type movement. The support table 250 is capable of translating up and down as the X-arm 216 performs a scissor-type motion. The four ends of the two arms of each set of X-shaped arms 216 are respectively connected to the four ends of the two arms of the other set of X-shaped arms 216 by four horizontal axes (including a first axis 214, a second axis 215, a third axis 218, and a fourth axis 219). For each set of X-shaped arms, the lower end of one arm is connected to the end of the first shaft 214, the upper end of the arm is connected to the end of the fourth shaft 219, the lower end of the other arm is connected to the end of the second shaft 215, and the upper end of the other arm is connected to the end of the third shaft 218.

As shown in fig. 6, 8-9, the hydraulic drive mechanism drives the support table 250 to vertically move up and down, and includes a hydraulic actuator 211 and a transmission bracket 212. In the hydraulic drive mechanism, one end of the hydraulic actuator 211 is connected to the transmission bracket 212, and the other end is connected to the base 23. The gear train carriage 212 is slidably disposed on a longitudinal rail 233 of the base 23. The transmission bracket 212 is provided with a pair of lower slide grooves 213 spaced apart in the lateral direction by a distance L.

Returning to fig. 6-7, the two ends of the x-shaped mechanism first shaft 214 extend into the two lower slide grooves 213, respectively. The two ends of the X-shaped mechanism second shaft 215 are pivotably connected to the pivot portion 232 of the base 23. The two ends of the third shaft 218 of the X-shaped mechanism extend into the two upper slide grooves 217 of the support table 250, respectively. The upper sliding groove 217 is located directly above the lower sliding groove 213 and is parallel to the lower sliding groove 213. The length of the upper sliding groove 217 is greater than the length of the lower sliding groove 213. Both ends of the X-shaped mechanism fourth shaft 219 are pivotably connected to the pivot portion 220 of the support table 250. The pivot portion 220 is located directly above the pivot portion 232. In some embodiments, the hydraulic drive mechanism is configured to be able to stop driving at any position and remain in a position where driving is stopped. In some embodiments, dual-powered lift device 24 also includes a hydraulic release controller (not shown). The hydraulic release controller is coupled to the hydraulic drive mechanism, and the hydraulic release controller is configured such that upon actuation of the hydraulic release controller, a hydraulic support force of the hydraulic drive mechanism is released such that the hydraulic actuator returns to an initial position under the weight of the lifting support apparatus.

As shown in fig. 10 and 11, the manual driving mechanism is integrally mounted on the transmission bracket 212, and drives the support table 250 to vertically move up and down. The manual driving mechanism includes a manual wheel 221, a decelerator 222, and a rotational motion and linear motion conversion mechanism 223. The manual wheel 221 is connected to an input shaft of a speed reducer 222, on an output shaft of which a rotary motion and linear motion conversion mechanism 223, such as a screw, is provided. A corresponding rotary motion and linear motion conversion mechanism, such as an internal thread, is provided at the central portion of the first shaft 214. The manual driving mechanism is configured to convert the rotational movement of the grip sheave 221 into the linear movement of the first shaft 214. The linear motion of the first shaft 214 causes the X-arm to perform a scissor-type motion, thereby translating the support table 250 up and down.

In other embodiments, the lifting support apparatus 2 does not include a dual power lifting device 24, but rather includes an electrically powered support mechanism. The electric supporting mechanism comprises a motor, a speed reducer, a rotary motion and linear motion conversion mechanism and an X-shaped mechanism. The construction of the X-shaped mechanism is substantially the same as in the previous embodiments. The motor is connected to the input shaft of the decelerator, the output shaft of which is connected to the rotary motion and linear motion conversion mechanism, the linear motion output portion of which is connected to the X-shaped mechanism first shaft 214.

The operation of the installation site evaluation test platform will be described below with reference to the accompanying drawings. When the inspection platform is evaluated using the mounting hole site described herein, the handle 231 of the lifting support device 2 is rotated from the space-saving folded position and locked in the unfolded position. As shown in fig. 1, the installation site evaluation and detection tool 1 is placed above the lifting support apparatus 2 such that the lower frame of the intermediate support portion 151 of the installation site evaluation and detection tool 1 surrounds the upper frame 252 of the support table 250 of the lifting support apparatus 2, the upper frame 252 defining the horizontal movement range of the intermediate support portion 151. This can avoid the unexpected upset of installation hole site aassessment testing platform after excessive aversion. The user pushes and pulls the installation site evaluation and detection platform by hand using the handle 231, and moves the installation site evaluation and detection platform to a position below a detection object (not shown) to be evaluated and detected, which has been lifted at a certain height.

Fig. 5 shows the lifting support device 2 in a zero lifting state (the mounted mounting hole site evaluation test fixture 1 is not shown). After placing the installation site evaluation test platform in a substantially aligned position under the test object to be evaluated and tested, the user actuates the hydraulic drive mechanism. The hydraulic actuator 211 pulls the drive train carriage 212 toward the pivot 232 of the base 23, causing the lower slide slot 213 to move toward the X-mechanism second axis 215. The movement of the lower slide groove 213 forces the X-shaped mechanism first shaft 214 with its end located in the lower slide groove 213 to move therewith. The distance between the first X-shaped mechanism shaft 214 and the second X-shaped mechanism shaft 215 gradually shortens, thereby allowing the X-shaped arm to perform a scissor-like motion, raising the support table 250 and the mounting hole position evaluation and detection tool 1 upward. Fig. 6 shows the end of travel of the hydraulic drive (the mounted mounting hole position evaluation and detection tool 1 is not shown). At this end of travel, the hydraulic actuator 211 reaches maximum travel, the end of the X-shaped mechanism first shaft 214 is still at the end of the lower slide groove 213 remote from the X-shaped mechanism second shaft 215 and abuts the end groove wall of the lower slide groove 213.

In any position deemed appropriate by the user, the driving of the hydraulic drive mechanism may be stopped without having to reach the end of travel of the hydraulic drive mechanism. Such as the positioning pins 11, 12 near the mounting hole to be evaluated and detected, a finer lifting can be achieved by switching the manual drive mechanism.

As shown in fig. 7, the user drives the manual wheel 221 by hand, and the rotation of the manual wheel 221 drives the input shaft of the speed reducer 222 to rotate, and the input shaft of the speed reducer 222 rotates to pass through the speed reducer and then output the rotation in a desired direction and at a desired rotation speed on the output shaft of the speed reducer, and the rotation of the output shaft of the speed reducer drives the rotation of the rotary motion and linear motion conversion mechanism, for example, the rotation of the screw rod. The corresponding rotational movement on the X-shaped mechanism first shaft 214 is accompanied by linear movement by a linear movement conversion mechanism (e.g., internal threads). The linear movement of the first X-shaped mechanism shaft 214 toward the second X-shaped mechanism shaft 215 causes the distance between the first X-shaped mechanism shaft 214 and the second X-shaped mechanism shaft 215 to continue to shorten, causing the X-shaped arm to continue to perform a scissor-like movement, thereby raising the support table 250 and the installation site evaluation detector 1 upward.

As mentioned above, the installation site evaluation platform is initially in a generally aligned state. The hand-held mounting hole site evaluation and detection tool 1 can be further adjusted for alignment at any time during the travel of the hydraulic drive mechanism and the travel of the manual drive mechanism. Since the plurality of planar ball bearings 253 are provided at the top of the upper protruding frame 252 of the support table 250 at intervals, the lower surface of the intermediate support portion 151 can be slid smoothly in any in-plane direction on the planar ball bearings 253, so that the resistance encountered when the installation site evaluation and detection tool 1 is held by hand to adjust alignment is small, and the position of the installation site evaluation and detection tool 1 can be easily adjusted by one hand. As the mounting hole position evaluation detecting tool 1 gradually rises, the distances between the positioning pins 11, 12 and the mounting hole position of the detection object become closer, and the accuracy of the user's observation of the alignment error becomes higher, so that the alignment of the positioning pins 11, 12 and the positioning holes is gradually completed in the process of gradually rising the mounting hole position evaluation detecting tool 1.

When the positioning pins 11, 12 gradually approach and are about to enter the positioning holes, the user manipulates the installation hole position to evaluate the horizontal position of the detection tool 1 so that the first positioning pin 11 and the second positioning pin 12 are aligned with the corresponding positioning holes of the detection object, respectively.

When the first positioning pin 11 and the second positioning pin 12 are aligned with the corresponding positioning holes of the detection object, respectively, the dome portion of the top tapered section 111 can be brought into the positioning holes as long as the position thereof is within a certain range, without necessarily completely overlapping the central axes of the positioning pins and the positioning holes. This is because, after the dome portion of the top tapered section 111 enters the positioning hole, as the positioning pin gradually goes deep into the positioning hole, the tapered and enlarged outer surface of the top tapered section 111 and the edge of the positioning hole abut against and slide against each other, guiding the positioning hole evaluation detecting instrument 1 to move so that the central axis of the positioning pin and the central axis of the positioning hole are gradually aligned. When the top tapered section 111 of the dowel pin is fully entered into the dowel hole, the middle cylindrical section 112 begins to enter the dowel hole. The diameter of the middle cylindrical section 112 is slightly smaller than the diameter of the positioning hole so that the middle cylindrical section 112 can smoothly enter the positioning hole without being unable to smoothly enter and be taken out due to friction force or the like. Because the upper diameter of the sleeve 13 is greater than the diameter of the locating hole, the upper surface of the radial flange of the upper portion of the sleeve 13 abuts the surface around the locating hole after the intermediate cylindrical section 112 has fully entered the locating hole.

If the central axis of the locating pins 11, 12 is too far from the central axis of the locating hole, resulting in the dome of the top tapered section 111 not being in a range where access to the locating hole is possible, the dome will abut against the lower surface of the test object around the locating hole. Under the pressure created by the dome against the lower surface of the test object around the locating hole, both the top tapered section 111 and the middle cylindrical section 112 of the locating pin can collapse into the sleeve 13. Such a collapsible design can avoid the dome of the top tapered section 111 damaging the surface around the locating hole. When the top tapered section 111 and the middle cylindrical section 112 of the dowel are retracted into the sleeve 13, the lower cylindrical section 116 correspondingly moves downward, protruding from the through hole 117. The step 115 prevents the top tapered section 111 and the middle cylindrical section 112 from completely falling out of the through hole 117.

After the first positioning pin 11 and the second positioning pin 12 completely enter the corresponding positioning holes of the detection object, a user observes the mounting hole positions to evaluate whether the matching hole positions 21 on the detection tool 1 can be aligned and attached with the mounting hole positions of the detection object.

If the matching hole 21 and the mounting hole are not horizontally aligned but partially or completely shielded when the mounting hole evaluating and detecting tool 1 is integrally attached to the surface of the object to be detected where the mounting hole is located, it is possible to determine that the mounting hole is erroneously horizontally assembled.

If a vertical gap exists between a certain matching hole 21 and the mounting hole when the mounting hole evaluating and detecting tool 1 is integrally attached to the surface on which the mounting hole of the object to be detected is located, or if a certain matching hole 21 and the mounting hole are attached together first before none of the other matching holes are attached, it is indicated that there is a displacement of the mounting hole in a direction perpendicular to the surface of the mounting hole, and when the amount of such displacement is larger than a tolerance that can be fine-tuned by mounting, it can be determined that there is an assembly dimension error.

When it is necessary to lower the installation site evaluation and detection tool 1, the manual wheel 221 is rotated in the reverse direction of the ascent, and the above manual transmission mechanism is operated in the reverse direction, so that the distance between the X-shaped mechanism first shaft 214 and the X-shaped mechanism second shaft 215 is increased, the X-shaped arm is made to perform a scissor-type movement in the opposite direction to the ascent, and the support table 250 and the installation site evaluation and detection tool 1 are lowered.

When the position shown in fig. 6 is reached, the manual wheel 221 is stopped to rotate, the hydraulic release controller is opened, the hydraulic driving mechanism slowly descends under the action of the self weight of the lifting support device, and the hydraulic actuator returns to the initial position as shown in fig. 5.

In the embodiment using the electric supporting mechanism, when the lifting operation is required, the user actuates the motor to rotate, so as to drive the input shaft of the speed reducer to rotate, and the input shaft of the speed reducer rotates to output the rotation of the required direction and the required rotating speed on the output shaft of the speed reducer after passing through the speed reducer, and the rotation of the output shaft of the speed reducer drives the rotation of the rotary motion and linear motion conversion mechanism, for example, the rotation of the screw rod. The corresponding rotational movement at the first axis of the X-shaped mechanism is translated with a linear movement conversion mechanism (e.g., internal threads). The linear motion of the first axial X-shaped mechanism second axial X-shaped mechanism shortens the distance between the first X-shaped mechanism shaft and the second X-shaped mechanism shaft, so that the X-shaped arm performs scissor-type motion, and the supporting table and the installation hole site assessment and detection device are lifted upwards. In this process, the manner in which the hand-held installation site evaluation detection tool adjusts alignment is the same as in the other embodiments.

When the installation hole site evaluation and detection device is required to be lowered, the motor is driven in the opposite direction, so that the distance between the first shaft of the X-shaped mechanism and the second shaft of the X-shaped mechanism is increased, the X-shaped arm performs scissor-type movement in the opposite direction to the lifting direction, and the supporting table and the installation hole site evaluation and detection device are lowered.

The mounting hole site evaluation and detection platform can complete rapid measurement, and can evaluate and detect the mounting hole site accurately and rapidly. The lifting support device disclosed by the utility model can stably support the installation hole site evaluation and detection appliance and rapidly and accurately attach to the installation hole site to be evaluated and detected.
