DETAILED DESCRIPTION

[0064] The following will be combined with the attached embodiment of the present invention Figure 1-Figure 9 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0065] In the description of the present invention, it should be understood that the terms "upper", "lower", "top surface", "bottom surface" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the positions or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0066] In this paper, for the convenience of description, Figure 6 The direction is set in the Y direction, wherein the push block moves along the Y direction under the drive of the first driving member, the clamping block moves along the X direction under the drive of the second driving member, and the direction from the clamping block to the product to be tested is the Z direction.

[0067] Combination Figure 1-Figure 9 As shown, the first aspect of the present invention provides a fixture structure 100, which is used to be installed on a positioning tool 1000, wherein the positioning tool 1000 is used to position and clamp a product to be tested 2000. Specifically, the fixture structure 100 is installed on the end surface of the positioning tool 1000 facing the product to be tested 2000, and the force application point of the fixture structure 100 on the product to be tested 2000 is located in the middle or approximately in the middle of the product to be tested 2000. Specifically, the product to be tested 2000 can be a B-pillar glass of a car.

[0068] like Figure 1 As shown, the fixture structure 100 includes a clamping block 101, a pushing block 102 and a first driving member 103, wherein the fixed end of the first driving member 103 is fixed on the bottom plate 200 of the positioning fixture 1000, and the driving end of the first driving member 103 is connected to the pushing block 102. Taking the first driving member 103 as a cylinder as an example, the fixed end of the first driving member 103 is the cylinder body of the cylinder, and the driving end of the first driving member 103 is the cylinder rod of the cylinder. It should be noted that the first driving member 103 is a cylinder, which is only a specific embodiment of the present invention. In practical applications, the first driving member 103 can also be set as a hydraulic cylinder or an electric push rod or other retractable driving member.

[0069] One end of the push block 102 is connected to the driving end of the first driving member 103, and the other end is in contact with the inclined surface 101a on the side wall of the block 101. The inclined surface 101a is inclined along the direction from the block 101 to the product 2000 to be tested, that is, the inclined surface 101a is inclined with respect to the Z direction.

[0070] The clamping block 101 is used to clamp the end face of the product to be tested 2000 facing the positioning tool 1000, and the first driving member 103 can drive the pushing block 102 to move in the direction close to or away from the clamping block 101, that is, the first driving member 103 can drive the pushing block 102 to move along the Y direction, and push the inclined surface 101a through the end face of the pushing block 102, so that the inclined surface 101a slides relative to the end face of the pushing block 102, thereby driving the clamping block 101 to move to apply force to the product to be tested 2000, that is, pushing the clamping block 101 to move along the Z direction.

[0071] It should be noted that when the inclined surface 101a is inclined along the direction from the top to the bottom of the block 101, toward the pushing block 102, when the pushing block 102 moves toward the block 101, the block 101 descends; when the inclined surface 101a is inclined along the direction from the top to the bottom of the block 101, toward the direction away from the pushing block 102, when the pushing block 102 moves toward the block 101, the block 101 rises.

[0072] like Figure 3 As shown, take the inclined surface 101a as an example, which is inclined along the direction from the top to the bottom of the card block 101, and is inclined toward the direction close to the push block 102. The inclination angle of the inclined surface 101a is greater than or equal to 30° and less than or equal to 60°. When the inclined surface 101a is within this value range, on the one hand, the problem of the slow descending speed of the card block 101 caused by too small an angle can be avoided, and on the other hand, the problem of difficulty in pushing the card block 101 caused by too large an angle can be avoided.

[0073] In the embodiment of the present invention, the product to be tested 2000 is taken as the B-pillar glass of an automobile as an example. Figure 3 As shown, when in use, the clamp structure 100 is fixed to the positioning fixture 1000, the positioning fixture 1000 is used to position and clamp the automobile B-pillar glass, and the clamping block 101 is clamped to the end face of the automobile B-pillar glass facing the positioning fixture 1000; then, the first driving member 103 is started, and drives the pushing block 102 to move in a direction close to the clamping block 101, so as to push the end face of the pushing block 102 to slide relative to the inclined surface 101a, thereby driving the clamping block 101 to descend, and then tightening the automobile B-pillar glass until the automobile B-pillar glass produces the same deformation as the actual installation, so as to measure whether the automobile B-pillar glass meets the installation and use requirements.

[0074] In some embodiments, the number of pushing blocks 102 is 1. In this case, an inclined surface 101a can be set to extend from one side of the pushing block 102 to the other side, that is, the bottom end of the pushing block 102 is the inclined surface 101a. It can be understood that the end surface of the pushing block 102 that cooperates with the inclined surface 101a can also be an inclined end surface.

[0075] It should be noted that the number of the push block 102 disclosed above is only one specific embodiment of the present invention. In practical applications, the number of the push blocks 102 may also be set to 2 or more. For example, the number of the push blocks 102 is 2 and they are respectively set on both sides of the card block 101. Figure 1 As shown, two push blocks 102 are symmetrically arranged about the block 101. By the two symmetrically arranged push blocks 102 pushing the block 101 at the same time, the forces exerted by the two push blocks 102 on the block 101 are in a straight line, which avoids the phenomenon that the block 101 is deflected due to the forces exerted on the block 101 when the two push blocks 102 are not in a straight line. At this time, the number of first driving members 103 can also be set to 2, which are arranged one-to-one with the push blocks 102, and the first driving member 103 is located at the end of the connected push block 102 away from the block 101; the number of first driving members 103 can also be set to 1, that is, one first driving member 103 is used to drive the two push blocks 102 to move at the same time, and at this time, the first driving member 103 can be a double-acting cylinder or a double-acting hydraulic cylinder, etc.

[0076] In some embodiments, Figure 3 As shown, the clamping block 101 includes a clamping portion 101-1 and a truncated table 101-2. Specifically, the top of the clamping portion 101-1 has a receiving area, and the receiving area is used to hook the first hook 2000a on the product to be tested 2000. It can be understood that the receiving area hooks the first hook 2000a on the product to be tested 2000, specifically, the receiving area is provided with a clamping groove 101-1a or a clamping hook that can clamp the first hook 2000a. Take the clamping groove 101-1a provided on the receiving area for clamping the first hook 2000a as an example, as shown in FIG. Figure 8 As shown, it should be noted that the clamping groove 101-1a can be formed by directly removing material from the clamping portion 101-1, or can be formed by splicing plates.

[0077] The top of the truncated platform 101-2 is connected to the clamping portion 101-1. Specifically, the side surface of the truncated platform 101-2 is an inclined surface 101a, and the end surface of the push block 102 abutting against the inclined surface 101a is an arc surface. Figure 4 As shown, the contact stability between the pushing block 102 and the clamping block 101 is improved by clamping the side of the truncated table 101 - 2 with the arc surface.

[0078] Furthermore, if Figure 3 As shown, the clamping block 101 further includes an elastic reset member 101 - 3 , one end of which is connected or abutted with one end of the truncated table 101 - 2 away from the clamping portion 101 - 1 , and the other end of which is abutted or connected with the positioning tool 1000 .

[0079] When the first driving member 103 drives the push block 102 to move toward the block 101, the elastic reset member 101-3 is in a compressed state, and the block 101 moves downward along the Z direction. When the first driving member 103 drives the push block 102 to move away from the block 101, the elastic reset member 101-3 rebounds, so that the block 101 moves upward along the Z direction.

[0080] Specifically, the elastic return member 101 - 3 is a spring or the like.

[0081] In order to facilitate driving the card block 101 to move along the X direction to detect the performance of the product 2000 to be tested, the present invention discloses that the fixture structure 100 also includes a sliding drive component 104. Specifically, the sliding drive component 104 is installed on the bottom plate 200 of the positioning tool 1000, and the driving end of the sliding drive component 104 is connected to the card block 101, which is used to drive the card block 101 to slide relative to the positioning tool 1000 to clamp or release the first hook 2000a. That is, the connection between the card block 101 and the bottom plate 200 of the positioning tool 1000 is achieved through the sliding drive component 104.

[0082] Furthermore, if Figure 2 As shown, the sliding drive assembly 104 includes a second drive member 104-1 and a connecting plate 104-2. Specifically, the fixed end of the second drive member 104-1 is fixed on the bottom plate 200 of the positioning tool 1000, and the driving end of the second drive member 104-1 is connected to the connecting plate 104-2.

[0083] It should be noted that the second driving member 104-1 can be any driving member that can drive the connecting plate 104-2 to move along the X direction. For example, the second driving member 104-1 is a cylinder, a hydraulic cylinder or an electric push rod. In this embodiment, the second driving member 104-1 is taken as a cylinder.

[0084] The block 101 is installed on the connecting plate 104-2. More specifically, a sliding hole is opened on the connecting plate 104-2 along the Z direction. A sliding cylinder 101-2a is provided at the bottom end of the cone 101-2 of the block 101. The sliding cylinder 101-2a is slidably connected to the sliding hole. The top end of the elastic reset member 101-3 is fixed in the sliding cylinder 101-2a, and the bottom end extends out of the bottom end of the sliding cylinder 101-2a and is connected or abutted with the bottom end of the sliding hole.

[0085] In order to facilitate the connection plate 104-2 to move along the X direction, the sliding drive assembly 104 also includes a slide rail 104-3. Specifically, the slide rail 104-3 is laid on the bottom plate 200 of the positioning tool 1000 along the X direction, and the connection plate 104-2 is slidably connected to the slide rail 104-3.

[0086] In order to facilitate the detection of the card block 101 sliding into place to ensure that the first hook 2000a is stuck, the present invention discloses that the sliding drive component 104 also includes a detection member 104-4. Specifically, the detection member 104-4 can be an in-place detection sensor installed on the second drive member 104-1, which detects whether the card block 101 is in place by detecting the piston position of the second drive member 104-1. If it is detected that the card block 101 is not in place, an alarm is issued.

[0087] The fixture structure 100 provided by the present invention takes the product to be tested as the B-pillar glass of an automobile, and the inclined surface 101a is inclined in the direction from the top end to the bottom end of the clamp block 101, toward the direction close to the push block 102, as an example, the fixture structure 100 is installed on the positioning fixture 1000, and the B-pillar glass of the automobile is positioned by the positioning fixture; then, the second driving member 104-1 of the sliding driving assembly 104 is started, and the clamp block 101 is driven to move along the X direction through the connecting plate 104-2 until the detection member 104-4 installed on the second driving member 104-1 detects The card block 101 receives an in-position signal. At this time, the card block 101 moves to the first hook 2000a that catches the B-pillar glass of the car, and the detection member 104-4 transmits the detected in-position signal to the second driving member 104-1, and the second driving member 104-1 stops moving; then, the pushing block 102 moves in the direction close to the card block 101, and the pushing block 102 interacts with the inclined surface 101a on the card block 101 to push the card block 101 to move downward along the Z direction, thereby generating a downward pulling effect on the B-pillar glass of the car to simulate the actual working condition of the B-pillar glass of the car.

[0088] In some embodiments, the clamp structure 100 further includes a guide member 105 having a guide groove 105a formed thereon and extending in a direction close to the clamping block 101. The push block 102 can be slidably installed in the guide groove 105a, and the guide groove 105a is used to guide the push block 102.

[0089] In this embodiment, taking the number of the guide member 105 as 1 and the number of the push blocks 102 as 2 as an example, the structure of the guide member 105 is as follows: Figure 5 As shown, specifically, the guide member 105 is installed on the base plate 200 of the positioning tool 1000, and a guide groove 105a is respectively opened on both sides of the guide member 105 to slideably install a push block 102 respectively, and the connecting plate 104-2 can drive the block 101 to move above the guide member 105 along the X direction, and the top end of the push block 102 extends to above the guide groove 105a to push the block 101.

[0090] Combination Figure 6-Figure 9 The second aspect of the present invention provides a positioning tool 1000, wherein: Figure 6As shown, the positioning tool 1000 includes a base plate 200, a positioning clamping assembly 300, and a clamp structure 100 as in any one of the above embodiments.

[0091] The positioning clamping assembly 300 and the fixture structure 100 are both installed on the bottom plate 200, and the positioning clamping assembly 300 is used to clamp and position the edge of the product to be tested 2000, and the fixture structure 100 is located in the middle of the bottom plate 200, and is used to position and tighten the product to be tested 2000. It can be understood that the middle position of the bottom plate 200 here is approximately located in the middle position of the bottom plate 200 along the X direction and the Y direction, so that the fixture structure 100 can apply force to the product to be tested 2000.

[0092] Specifically, the present invention discloses a positioning clamping assembly 300 including a buckle 301, a positioning block 302, a positioning pin 303 and a pressing drive member 304, all of which are installed on the base plate 200, wherein the buckle 301 and the positioning block 302 are respectively located at both ends of the clamp structure 100 along the X direction.

[0093] The buckle 301 is used to lock the second hook 2000b of the first end of the product to be tested 2000. Figure 7 As shown, the positioning block 302 is inserted into the first positioning hole opened on the second end of the product to be tested 2000 to position the first positioning hole. Specifically, the first positioning hole is a direction hole. Correspondingly, the positioning block 302 is a square block to prevent the product to be tested 2000 from rotating.

[0094] The positioning pins 303 are arranged on both sides of the positioning block 302 along the Y direction, and are respectively used for inserting into and positioning the second positioning holes on the product 2000 to be tested.

[0095] The pressing driving member 304 is used to press the product 2000 to the boss of the positioning pin 303. Specifically, the pressing driving member 304 is a pressing cylinder, etc. That is, the pressing driving member 304 cooperates with the positioning pin 303 and the positioning block 302 to not only position the product 2000, but also press the product 2000.

[0096] In some embodiments, the positioning tool 1000 further includes a calibration block 400 , which is disposed on the base plate 200 . Specifically, the calibration block 400 is detachably mounted on the base plate 200 by fasteners such as bolts.

[0097] like Fig. 9 As shown, the calibration block 400 has a step 400a, which is used to calibrate the probe of the detection equipment. Specifically, the probe detects the height of the step 400a on the calibration block 400. The probe can detect the height of the step 400a on the calibration block 400 at intervals, and the stability of the machine where the probe is located can be determined based on the changes in the measured step 400a height data.

[0098] A detection hole 400b is provided on the calibration block 400, and the detection hole 400b is used to calibrate the detector of the detection equipment.

[0104] In order to facilitate the movement of the entire positioning tool 1000, the present invention discloses that handles 500 are respectively provided at both ends of the bottom plate 200. Specifically, the handles 500 are detachably mounted on the bottom plate 200 by fasteners such as bolts.

[0105] Furthermore, the present invention discloses that a light-transmitting hole 200a is also provided on the bottom plate 200, and a light source is provided at the light-transmitting hole 200a for lighting from the bottom end of the bottom plate 200 to illuminate the convex portion of the product 2000 to be tested, thereby detecting the convex portion.

[0106] Taking the product to be tested 2000 as a B-pillar glass of an automobile as an example, the convex part of the B-pillar glass of the automobile can be illuminated through the light-transmitting hole 200 a , thereby facilitating the detection of the three-dimensional morphology of the B-pillar glass of the automobile.

[0107] Taking the product 2000 to be tested as the B-pillar glass of an automobile, and the inclined surface 101a of the block 101 of the fixture structure 100 is inclined along the direction from the top to the bottom of the block 101, toward the direction close to the pushing block 102, as an example, when the positioning fixture 1000 provided by the present invention is used, the B-pillar glass of the automobile is inserted into the positioning fixture 1000, so that the buckle 301 on the positioning fixture 1000 clamps the second hook 2000b on the B-pillar glass of the automobile, and the positioning block 302 on the positioning fixture 1000 is inserted into the first positioning hole opened on the B-pillar glass of the automobile, and the positioning pins 303 on both sides of the positioning block 302 are respectively inserted into the corresponding second positioning holes on the B-pillar glass of the automobile.
