secondly, the auxiliary clamp cannot shield or cover the small-diameter inclined hole, and the small-diameter inclined hole is required to be ensured to be in a naked state; when the thermostat housing tooling is completed, the positions of the small-diameter inclined holes are required to be adjusted, specifically, the design sizes of the small-diameter inclined holes are marked by taking a design reference as a reference, the deflection angles of the X-direction deflection plate 4 and the Y-direction deflection plate 5 are correspondingly adjusted according to the inclination angles on the small-diameter inclined hole design drawing, the X-direction deflection plate 4 deflects by taking the X axis of a horizontal plane as an axis, and the Y-direction deflection plate 5 deflects by taking the Y axis of the horizontal plane as an axis, so that the small-diameter inclined holes on the thermostat housing are correspondingly enabled to deflect by corresponding angles according to the design angles marked by the small-diameter inclined holes, the small-diameter inclined holes on the thermostat housing are enabled to be in a vertical state and are enabled to be in a detection station so as to correspond to the small-diameter inclined hole detection mechanism 3, and then parameter detection is carried out on the small-diameter inclined holes on the thermostat housing by the small-diameter inclined hole detection mechanism 3; the small-diameter inclined hole detection mechanism 3 comprises a two-way moving assembly and a detection assembly, the two-way moving assembly has linear movement degrees of freedom along two directions of horizontal and vertical, the detection assembly is arranged on the moving assembly, the detection assembly comprises a small-diameter detection probe tube 6 and two groups of probe assemblies which are arranged in a rotating way, the two groups of probe assemblies are symmetrically arranged on the side wall of the small-diameter detection probe tube 6, the probe assemblies comprise detection probes 7 and strain gauges 8, the detection probes 7 are perpendicular to the small-diameter detection probe tube 6 and slide to penetrate through the small-diameter detection probe tube 6, the two groups of probe assemblies cannot interfere, the strain gauges 8 are vertically arranged in the small-diameter detection probe tube 6, one end of the detection probe 7 is connected with the strain gauges 8, the position of the probe assembly is adjusted through the two-way moving assembly, the detection probes 7 correspond to the small-diameter inclined hole, then the two-way moving assembly drives the small-diameter detection probe tube 6 to move downwards, the small-diameter detection probe tube 6 is led to enter the small-diameter inclined hole, the detection probe 7 is led to contact the inner wall of the small-diameter inclined hole, the small-diameter detection probe tube 6 is rotated, the detection probe 7 is led to move along the circumferential direction of the small-diameter inclined hole, the change of the size of the inner wall of the small-diameter inclined hole correspondingly drives the detection probe 7 to move on the small-diameter detection probe tube 6, the strain gauge 8 is deformed by the detection probe 7 in different degrees or different directions, then the small-diameter detection probe tube 6 is driven by the two-way moving assembly to move downwards, the detection probe 7 continuously detects the next circumferential surface of the small-diameter inclined hole, the detection probe 7 covers the inner wall of the whole small-diameter inclined hole to detect through the circumferential rotation and the axial movement of the small-diameter detection probe tube 6, the condition of missing detection is avoided, the size change range is judged according to the deformation degree of the strain gauge 8, the condition of the inner wall of the small-diameter inclined hole is simulated according to the deformation degree of the strain gauge 8, parameters such as the diameter, the angle, the smoothness of the hole wall and the like of the small-diameter inclined hole are measured, so that the small-diameter inclined hole can be automatically detected, and the detection precision and the detection efficiency are high; by adopting the detection structure, the design of the traditional sensor element is avoided, the design size of the probe assembly is greatly reduced, the probe assembly can enter the small-diameter inclined hole to carry out the covered comprehensive detection, and the detection precision and the detection efficiency are greatly improved relative to the manual detection.
In the second embodiment, because the small diameter detection probe tube 6 has smaller size, there is not enough space in the circumferential direction to arrange two groups of probe assemblies, in order to ensure that the two groups of probe assemblies are smoothly installed and do not interfere, therefore, on the basis of the first embodiment, as shown in fig. 1 to 4, the detection probe 7 comprises a horizontal probe 9 and a vertical probe 10, the vertical probe 10 is positioned in the small diameter detection probe tube 6, the horizontal probe 9 is in a truncated cone shape, the large diameter end of the horizontal probe 9 is slidably arranged in the small diameter detection probe tube 6 and is connected with the bottom end of the vertical probe 10, the top end of the vertical probe 10 is connected with a horizontal connecting needle 11, the horizontal connecting needle 11 is connected with a strain gauge 8, the strain gauges 8 in the two groups of probe assemblies are staggered along the axial direction of the small diameter detection probe tube 6, the lengths of the vertical probes 10 in the two groups of probe assemblies are different, the vertical probe 10 is used for correspondingly connecting the strain gauges 8, and through the arrangement of the vertical probes 10, the horizontal probes 9 in the two groups of probe assemblies are ensured to be at the same height, and meanwhile, the vertical probes 10 can be connected with the corresponding strain gauges 8 in different height directions, so that the strain gauges 8 in the two groups of probe assemblies are staggered along the axial direction of the small-diameter detection probe tube 6, the interference of the two groups of probe assemblies is avoided, meanwhile, the circumferential arrangement space of the two groups of probe assemblies is reduced, the two groups of probe assemblies are arranged in an axially staggered manner by utilizing the characteristic that the axial space of the small-diameter detection probe tube 6 is large, and therefore, the two groups of probe assemblies can be well installed, and the horizontal probes 9 in the two groups of probe assemblies extend out of the small-diameter detection probe tube 6 in the same horizontal plane for detection; the middle part of the vertical probe 10 is fixedly connected with a telescopic needle 12, one end of the telescopic needle 12 far away from the vertical probe 10 is connected with an adjusting rotary seat 13, the adjusting rotary seat 13 penetrates through the side wall of the small-diameter detection

14 respectively prop against the vertical probe 10 and the adjusting rotary seat 13, the spring 14 is connected with the middle part of the vertical probe 10, so that the whole detection probe 7 is stressed symmetrically and uniformly, the detection probe 7 can stably move on the small-diameter detection probe tube 6, during detection, the extending length of the two horizontal probes 9 is adjusted firstly according to the size of a small-diameter inclined hole, the distance between the most distant points between the two horizontal probes 9 is ensured to be larger than the diameter of the small-diameter inclined hole, and the specific adjusting mode is that the adjusting rotary seat 13 is rotated by using a screwdriver, and a cross groove is arranged at the outer end of the adjusting rotary seat 13, the screw driver is convenient to drive the adjusting screw seat 13 to rotate, the adjusting screw seat 13 stretches out or stretches into the small-diameter detection probe tube 6 to drive the whole detection probe 7 to move through the spring 14, so that the stretching length of the horizontal probe 9 from the small-diameter detection probe tube 6 is adjusted, the stretching lengths of the two groups of detection probes 7 are consistent, after the adjustment is finished, the position of the detection probe 7 is stabilized through the threaded connection of the adjusting screw seat 13, then the small-diameter detection probe tube 6 is driven to move downwards by the two-way moving assembly, because the distance between the farthest points of the two horizontal probes 9 is larger than the diameter of the small-diameter inclined hole, the horizontal probe 9 can be propped against the top of the small-diameter inclined hole, and because the horizontal probe 9 is in the shape of a circular table, the horizontal probe 9 can move into the small-diameter detection probe tube 6 after being extruded, the horizontal probe 9 can smoothly enter the small-diameter inclined hole, the horizontal probe 9 can be propped against the inner wall of the small-diameter inclined hole under the reaction force of the spring 14, the distance between the farthest points of the two horizontal probes 9 is designed to be larger than the diameter of the small-diameter inclined hole, and the purpose is that after the horizontal probes 9 are propped against the inner wall of the small-diameter inclined hole, the springs 14 are in a compressed state, so that the horizontal probes 9 can correspondingly move towards the inside or the outside of the small-diameter detection probe tube 6 according to the dimensional change of the inner wall of the small-diameter inclined hole, and the specific detection process is as follows: after the horizontal probe 9 enters the small-diameter inclined hole, the horizontal probe 9 drives the vertical probe 10 to squeeze the strain gauge 8 to deform, the inner diameter of the small-diameter inclined hole is reflected by deformation change of the strain gauge 8 before entering, namely, when the strain gauge 8 is in a normal state, the distance between the two horizontal probes 9 is a comparison value, after the horizontal probe 9 enters the small-diameter inclined hole, the horizontal probe 9 moves inwards to squeeze the strain gauge 8, the deformation strength of the strain gauge 8 is in direct proportion to the inward moving distance of the horizontal probe 9, so that the moving value of the horizontal probe 9 is obtained according to the deformation degree of the strain gauge 8, the moving value of the two horizontal probes 9 is subtracted from the comparison value to obtain the inner diameter of the small-diameter inclined hole, the moving distance of the horizontal probe 9 is reflected by the deformation degree of the strain gauge 8, the inner wall condition and the size of the small-diameter inclined hole are reflected, the axial movement and the rotational freedom degree of the small-diameter detection probe 6 are matched, when the inner diameter of the small-diameter inclined hole is increased, the horizontal probe 9 moves outwards under the reaction force of the spring 14, at the moment, the deformation of the strain gauge 8 is weakened, the inner diameter is increased at the moment, when the inner diameter of the small-diameter inclined hole is reduced, the horizontal probe 9 is extruded to move towards the small-diameter detection probe tube 6 to continuously extrude the strain gauge 8, so that the whole inner wall size condition of the small-diameter inclined hole can be simulated, whether the size change condition of the small-diameter inclined hole meets the standard in the error range is judged, meanwhile, the inner wall size condition also reflects the smoothness of the inner wall to judge whether the friction degree meets the requirement, when the horizontal probe 9 penetrates out of the small-diameter inclined hole, the horizontal probe 9 is reset, the reset is the detection end point, and the point of inwards moving the horizontal probe 9 into the small-diameter inclined hole is the detection start point, the distance between the detection starting point and the detection end point, in which the small-diameter detection probe 6 moves axially, is the depth of the small-diameter inclined hole, so that the depth parameter of the small-diameter inclined hole can be detected.
