Description

Technical Field

[0001] This utility model relates to the field of pneumatic probe technology, and more specifically, to a floating anti-collision pneumatic probe. Background Technology

[0002] In the fields of industrial automation and precision measurement, pneumatic probes are widely used as an important measuring tool for measuring the diameter of workpieces of various sizes and shapes.

[0003] A search revealed that patent application CN202222108061.2 discloses a floating pneumatic probe device comprising a positioning mechanism and a measuring mechanism. The positioning mechanism includes a support base, a top plate, and a bottom plate. The measuring mechanism includes a probe and a main body, which are connected. The outer side of the main body is slidably connected to the positioning mechanism, allowing the main body to slide relative to it in the vertical direction. The bottom of the main body is elastically connected to the bottom plate. A limiting hole is provided in the top plate, and the probe is positioned within the limiting hole, with its radial diameter smaller than the hole diameter. When measuring a hole in a workpiece, by slidably connecting the outer side of the main body to the positioning mechanism, elastically connecting the bottom of the main body to the bottom plate, and positioning the probe within the limiting hole with its radial diameter smaller than the hole diameter, the measuring mechanism can float relative to the positioning mechanism. During measurement, the main body can slide up and down, and the probe can float and insert into the hole to measure the hole diameter. This eliminates the need for a separate measuring fixture, simplifying the measurement process. However, the following drawbacks still exist:

[0004] (1) The existing pneumatic probes can only float vertically and are not suitable for horizontal floating. The pneumatic probes are easily damaged by horizontal collisions and have poor anti-collision performance.

[0005] In existing pneumatic probes, the elastic components are difficult to replace after prolonged use and damage, and it is also inconvenient to replace worn sliding components.

[0006] Therefore, we made improvements and proposed a floating anti-collision pneumatic probe. Utility Model Content

An installation head is installed at both ends of the assembly frame. A nut is threaded onto the end of the installation head near the bearing seat, and a bearing is fixedly connected to the end of the installation head away from the bearing seat. A connecting shaft is fixedly connected to the inner wall of the inner ring of the bearing, and a roller is fixedly connected to the connecting shaft.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment proposes a floating anti-collision pneumatic probe, including a support base 1. A pneumatic probe body 2 is provided on one side of the support base 1. Two clips 3 are symmetrically attached to the bottom of the pneumatic probe body 2. The two ends of the clips 3 are connected by a first bolt assembly 4. A movable seat 5 is fixedly connected to the bottom of the two clips 3. A bearing seat 6 is provided on the outer side of the movable seat 5. A set of first fixing plates 7 are uniformly fixedly connected to the outer peripheral side wall of the movable seat 5. A set of second fixing plates 8 corresponding to the positions of the first fixing plates 7 are uniformly fixedly connected to the inner side wall of the bearing seat 6. A first spring 9 is fixedly connected between adjacent first fixing plates 7 and second fixing plates 8. A vertical floating structure 10 is provided on the lower side of the bearing seat 6. A guide structure 11 is provided on the bearing seat 6. The first spring 9 can buffer the horizontal collisions received by the pneumatic probe body 2, allowing the movable seat 5 to float in the horizontal direction, thereby enhancing the anti-collision performance of the pneumatic probe.

[0031] like Figure 1 , Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, the vertical floating structure 10 further includes a first connecting block 1001 fixed at the center of the lower end face of the support 6. The first connecting block 1001 is connected to a first connecting head 1003 via a second bolt assembly 1002. A second spring 1004 is fixedly connected to the lower end face of the first connecting head 1003. A second connecting head 1005 is fixedly connected to the bottom end of the second spring 1004. A second connecting block 1007 is connected to the second connecting head 1005 via a third bolt assembly 1006. The bottom end of the second connecting block 1007 is fixedly connected to the support 1. The second spring 1004 provides vertical buffering for the support 6, allowing the probe to float up and down.

[0032] like Figure 2 As shown, in a preferred embodiment, based on the above method, the number of the second bolt assembly 1002 and the third bolt assembly 1006 are both two, and both the second bolt assembly 1002 and the third bolt assembly 1006 are combinations of bolts and nuts; this ensures the stability of the assembly connection and also facilitates disassembly and replacement.

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the guide structure 11 further includes an assembly frame 1101 fixed to the outer wall of the bearing seat 6 near the support seat 1. Mounting heads 1102 are installed at both ends of the assembly frame 1101. A nut 1103 is threadedly connected to the end of the mounting head 1102 near the bearing seat 6, and a bearing 1104 is fixedly connected to the end of the mounting head 1102 away from the bearing seat 6. A connecting shaft 1105 is fixedly connected to the inner wall of the inner ring of the bearing 1104. Rollers 1106 are fixedly connected to the support base 1. A guide plate 1107 is provided between the two rollers 1106. Assembly columns 1108 are fixedly connected to both ends of the bottom of the guide plate 1107. The assembly columns 1108 are connected to the support base 1 by hex bolts. The mounting head 1102 and nut 1103 facilitate installation and disassembly, thereby facilitating the replacement of worn rollers 1106 and ensuring the accuracy of guidance. The assembly columns 1108 facilitate the installation and disassembly of the guide plate 1107 and the support base 1, thereby facilitating subsequent replacement.

[0034] like Figure 4 As shown, in a preferred embodiment, based on the above method, both ends of the assembly frame 1101 are provided with square through holes that cooperate with the mounting head 1102; the square through holes facilitate the assembly of the mounting head 1102 and also ensure the stability of the mounting head 1102.

[0035] like Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, a limiting piece 12 is further provided on the upper side of the movable seat 5. The two ends of the limiting piece 12 are respectively connected to the fixing post 13 by internal hex bolts. The bottom end of the fixing post 13 is fixedly connected to the bearing seat 6. The limiting piece 12 can conveniently limit the movable seat 5 and prevent the movable seat 5 from moving vertically.

[0036] Specifically, when this floating anti-collision pneumatic probe is in use: when the pneumatic probe body 2 is subjected to a horizontal collision, the pneumatic probe body 2 moves horizontally, which in turn drives the frame 3 and the moving seat 5 to move horizontally. The movement of the moving seat 5 causes the first spring 9 to deform, which can protect the pneumatic probe body 2 from collision and prevent it from being damaged. If the pneumatic probe body 2 is subjected to a vertical collision force, the second spring 1004 deforms, and at the same time the support seat 6 moves vertically. The movement of the support seat 6 drives the roller 1106 to move. The roller 1106 slides vertically on the guide plate 1107, thereby enabling the pneumatic probe body 2 to float vertically.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
