Wherein, the fixed plate 10 and the floating plate 30 mainly play a role of supporting and fixing, and are used for installing and arranging parts such as the telescopic component 40, the floating rod 50, the first position sensor 12, the reference block 31 and the like; the fixing plate 10 is used for connecting the supporting component 20, the floating measuring head is close to or far away from the workpiece 1 to be measured through the supporting component 20, the floating plate 30 is arranged close to the fixing plate 10 at intervals, a telescopic component 40 is arranged between the floating plate 30 and the fixing plate 10, and the telescopic component 40 can be compressed to enable the floating plate 30 and the fixing plate 10 to be close to each other; one end of the floating rod 50 is fixed on the floating plate 30, and the other end extends to the side of the fixed plate 10 and passes through a preset through hole 11 on the fixed plate 10; the first position sensor 12 is provided on the fixed plate 10 for detecting a position signal of the floating rod 50 penetrating through the through hole 11; the reference block 31 is arranged on one side of the floating plate 30 away from the fixed plate 10 and is used for contacting the workpiece 1 to be measured to construct a measurement reference surface; the floating rods 50 each have a large-diameter section rod body and a small-diameter section rod body, the floating plate 30 approaches the workpiece 1 to be measured, the reference block 31 of the floating plate contacts the workpiece 1 to be measured, the fixed plate 10 is pushed to move to the small-diameter section rod body 51 along the floating rod 50 to realize floating adjustment, and when the fixed plate 10 moves to the lowest position of the small-diameter section rod body 51, the first position sensor 12 detects the position signal of the floating rod 50 and starts detection.
According to the floating measuring head provided by the invention, when the floating measuring head specifically works, the supporting component 20 drives the whole floating measuring head to extend into the workpiece 1 to be measured, the reference block 31 arranged on the floating plate 30 is firstly contacted with the workpiece 1 to be measured, the telescopic component 40 arranged between the floating plate 30 and the fixed plate 10 is compressed due to blocking, the fixed plate 10 moves along the rod length direction of the floating rod 50, and when the fixed plate 10 moves to the small-diameter section rod body 51 of the floating rod 50, a gap exists between the through hole 11 reserved on the fixed plate 10 and the small-diameter section rod body 51 so as to allow floating adjustment of the floating plate 30, the reference block 31 arranged on the fixed plate is better attached to the workpiece 1 to be measured to construct a measuring reference plane, and when the fixed plate 10 moves to the lowest position of the small-diameter section rod body 51, the first position sensor 12 detects the position signal of the floating rod 50 and starts detection.
The floating measuring head provided by the invention realizes the floating of a certain angle when being attached to the workpiece 1 to be measured, thereby ensuring that the floating measuring head is perfectly attached to the workpiece 1 to be measured, and further ensuring the accuracy of measured data.
According to the floating measuring head provided by the invention, the main body structure of the floating measuring head is constructed through the floating plates 30 and the fixed plates 10 which are arranged adjacently at intervals, and the telescopic component 40 and the floating rod 50 which are arranged between the floating plates 30 and the fixed plates 10 are matched, so that the reverse thrust of the floating measuring head when the floating measuring head is close to the workpiece 1 to be measured is skillfully utilized, the telescopic component 40 is compressed, the movement of the fixed plates 10 on the floating rod 50 is realized, further the floating adjustment of the floating plates 30 on the surface of the workpiece 1 to be measured is realized, the tolerance of the workpiece 1 to be measured during production and manufacture is adapted, and the accuracy of measured data is ensured; the floating measuring head has the advantages of simple structure and convenient use, and can meet the measurement requirements of depth dimensions of various workpieces.
In the present invention, the amount of the floating plate 30 floating on the surface of the workpiece 1 to be measured depends on the gap between the small diameter rod 51 of the floating rod 50 and the through hole 11 and the gap between the floating rods 50; the angular float of the floating plate 30 depends on the ratio of the guide length (i.e., the length of the small diameter rod 51) to the floating clearance (the clearance of the small diameter rod 51 from the through hole 11).
According to the floating probe provided by the invention, the telescopic assembly 40 is used for driving the floating plate 30 and the fixed plate 10 to move away from each other to the initial position, in the process, the fixed plate 10 moves from the small diameter section rod body 51 to the large diameter section rod body 52 along the rod length direction of the floating rod 50, and forms a guiding limit fit with the large diameter section rod body 52, in order to provide a closing signal for the measuring assembly, in some embodiments, the floating probe further comprises a second position sensor 13, and the second position sensor 13 is arranged on the fixed plate 10 and is used for detecting the position signal of the floating rod 50 after the telescopic assembly 40 returns and closing the detection, namely closing the measuring assembly.
In some embodiments, the telescopic assembly 40 is a cylinder which is fixed to the floating plate 30, and the end of the piston rod of which is fixed to the fixed plate 10. When the floating probe is close to the workpiece 1 to be measured, the reference block 31 arranged on the floating plate 30 is firstly close to the workpiece 1 to be measured, the cylinder at the moment starts to be compressed due to blocking, the fixed plate 10 starts to move to the position of the small-diameter section rod body 51 along the floating rod 50 so as to realize floating adjustment of the floating plate 30, and when the fixed plate 10 moves to the lowest position of the small-diameter section rod body 51, the first position sensor 12 detects a position signal of the floating rod 50 and starts detection.
After the detection is completed, the floating measuring head starts to separate from the workpiece 1 to be detected, at this time, the cylinder provides a restoring force to enable the fixed plate 10 and the floating plate 30 to be far away from each other, and the fixed plate 10 moves to the large-diameter section rod body 52 along the rod length direction of the floating rod 50 so as to realize guiding and limiting cooperation.
It should be noted that, in the present invention, the supporting component 20 drives the entire floating probe to contact the workpiece 1 to be measured to achieve measurement, and in order to avoid generating additional torque to ensure more stable measurement, the mounting position of the cylinder is preferably the center position of the floating plate 30. Furthermore, in order to measure the parameter of the central position of the workpiece 1 to be measured, the floating probe is further provided with an indirect measurement assembly, and as shown in fig. 4 and 5, the indirect measurement assembly comprises a slide fixing bracket 34 extending away from the floating plate 30, the slide fixing bracket 34 is provided with a pneumatic slide 35, the pneumatic slide 35 is provided with a third displacement sensor 36 and a bracket 37 extending to the side where the cylinder is located, and the bracket 37 is provided with a spherical contact 38.
In the specific use process, before the cylinder is compressed, the spherical contact 38 on the bracket 37 will contact the workpiece 1 to be measured, push the bracket 37 and drive the pneumatic slide block 35 to move, until the bracket 37 contacts the cylinder, push the compression cylinder, the third displacement sensor 36 arranged on the pneumatic slide block 35 can record the movement amount; the parameter to be measured of the central position corresponding to the air cylinder is converted into the moving amount of the pneumatic slide block 35 through the indirect measuring assembly, so that the parameter measurement of the central position is indirectly realized.
It should be noted that, in order to ensure quick and stable recovery of the pneumatic slide 35, a spring (not shown in the drawing) is sleeved on the slide guide rod 39 of the pneumatic slide 35, and is compressed in the process that the bracket 37 moves and contacts with the air cylinder, and after the measurement is completed, the elastic force of the spring can drive the pneumatic slide 35 to recover to the initial position to wait for the measurement of the next workpiece 1 to be measured.
In some embodiments, the telescoping assembly 40 is a spring having one end secured to the floating plate 30 and the other end secured to the fixed plate 10. The working principle of the floating probe is the same as that of the telescopic assembly 40 when it is a cylinder, and will not be described here again.
After the detection, the spring provides a restoring force to separate the fixed plate 10 and the floating plate 30 from each other. The inventor of the present application has found that in the floating gauge head provided by the present application, by using the air cylinder as the telescopic assembly 40, it is possible to perform accurate measurement with high accuracy in the case where the positioning accuracy of the workpiece 1 to be measured is not high as compared with a spring, and it is presumed that the air cylinder can accurately adjust the force value of floating opening and resetting by the precision pressure reducing valve, and is more reliable as compared with a spring.
In some embodiments, the floating probe further comprises an in-situ sensor 33, and the in-situ sensor 33 is disposed at two sides of the floating plate 30 and is used for detecting in-situ signals of the workpiece 1 to be measured. After the signal of the workpiece 1 to be measured is detected by the in-situ sensor 33, the detection of the measuring component is only allowed to be started. It should be noted that, by setting the two in-situ sensors 33 to detect the workpiece 1 to be detected and interlocking the measured values, the invention can well avoid the uploading of error data to the system caused by equipment abnormality and avoid the influence on the subsequent production process.
In some embodiments, a positioning bushing 111 is disposed in the through hole 11 of the fixing plate 10, and the positioning bushing 111 forms a guiding and limiting fit with the large-diameter section rod body 52 of the floating rod 50.
In some embodiments, a stop 53 is provided at the upper end of the floating rod 50 to form a stop with the upper surface of the fixed plate 10. By the arrangement of the stop block 53, the floating rod 50 is prevented from falling out of the through hole 11 on the fixed plate 10 due to the excessive restoring force of the telescopic assembly 40.
In the present invention, the measuring component is used for measuring the workpiece 1 to be measured, and in a specific embodiment of the present invention, the measuring component is a plurality of displacement sensors 32 arranged on one side of the floating plate 30 away from the fixed plate 10; the displacement sensor 32 includes a first displacement sensor 321 disposed on the plane of the reference block 31 and a second displacement sensor 322 remote from the plane of the reference block 31.
In a specific application, the reference plane is measured by the first displacement sensor 321 located on the plane of the reference block 31, and the depth measurement of the workpiece 1 to be measured is realized by the second displacement sensor 322 located away from the plane of the reference block 31.
In a specific application example of the present invention, the workpiece 1 to be tested is specifically a battery pack case, and by accurately measuring the battery pack case, in a subsequent gluing process of the heat-conducting glue, accurate input is provided for the servo constant displacement pump, so that tight adhesion of the battery module and the battery pack case through the heat-conducting glue is realized, and good heat dissipation is further realized.
More specifically, three first displacement sensors 321 are arranged, and each first displacement sensor is used for correspondingly measuring a reference plane constructed by three reference blocks 31 on the upper end surface of the battery pack shell; the second displacement sensor 322 is arranged with a plurality of zones to refine the bottom of the battery pack case as much as possible to achieve more accurate depth measurements of the battery pack case. In a specific embodiment of the present invention, 9 second displacement sensors 322 are arranged. When the glue coating amount is input to the servo constant displacement pump, the number of the second displacement sensors 322 can be increased or decreased according to the number of data points of specific requirements, or the glue coating amount of more points can be calculated through linear simulation, for example, the depth of the battery pack case measured by the point A is 100mm, the depth of the battery pack case measured by the point B is 99mm, the depth of the battery pack case at the middle point between the point A and the point B is 99.5mm through linear simulation, and then the glue coating amount is obtained through the height operation of the battery module corresponding to the point.
In some embodiments, the support assembly 20 is a robot, a KBK telescopic arm, or a vertical slipway.
It should be noted that, the floating probe of the present invention is specifically approaching to or separating from the workpiece 1 to be measured through the supporting component 20, that is, the supporting component 20 is a measurement moving unit of the floating probe of the present invention, so that different supporting components 20 can be selected in different situations, for example, when in manual measurement or standby measurement, a KBK telescopic arm is used as the supporting component 20; for example, when the measuring positions of the workpiece 1 to be measured are small, the vertical sliding table is used as the supporting component 20; for example, when there are more measurement positions of the workpiece 1 to be measured, the robot may be used as the support assembly 20 to fully exert the flexibility of the robot, as shown in fig. 4 and 6.
Further, in the present invention, the fixing plate 10 is further provided with a mounting seat 14 for connecting the support assembly 20.
