DETAILED DESCRIPTION

[0025] The utility model provides a main hub hole penetration detection device. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0026] See also Figure 1-Figure 4 The utility model provides a main hub hole penetration detection device, comprising a machine platform 1, a tool 2 and a plurality of first brackets 3 arranged on the machine platform 1, and a first hole penetration mechanism 4 and a second hole penetration mechanism 5 respectively arranged on the corresponding first brackets 3; the tool 2 is used to position a workpiece 10; the first hole penetration mechanism 4 and the second hole penetration mechanism 5 each comprise a first telescopic member 41, a first sleeve 42 fixedly connected to the output end of the first telescopic member 41, a first guide shaft 43 arranged in the inner cavity of the first sleeve 42, and a first guide shaft 43 arranged in the inner cavity of the first sleeve 42. A first needle 44 is fixedly connected to the front end of the first guide shaft 43, a first limiting plate 45 is fixedly connected to the rear end of the first guide shaft 43, and a first restoring member 46 is sleeved on the first guide shaft 43; the first limiting plate 45 is located outside the first sleeve 42, and the first restoring member 46 is used to drive the first needle 44, the first guide shaft 43 and the first limiting plate 45 to reciprocate along the length direction of the first sleeve 42; the first needle 44 is toward the first hole position 20 or the second hole position 30 corresponding to the workpiece 10.

[0027] That is to say, each first bracket 3 is provided with a first hole position penetration mechanism 4 and a second hole position penetration mechanism 5 of the same structure. Since the first hole position 20 and the second hole position 30 on the workpiece 10 are close to each other, and the first hole position penetration mechanism 4 and the second hole position penetration mechanism 5 are relatively large in volume, in this embodiment, the first hole position penetration mechanism 4 is inclined and the second hole position penetration mechanism 5 is horizontally arranged. The first bracket 3 is provided in four numbers, corresponding to the four first holes 20 and the four second holes 30 on the workpiece 10.

[0028] When it is necessary to detect the penetration of each hole position on the workpiece 10, the workpiece 10 is placed on the tooling 2, and the workpiece 10 is positioned by the tooling 2 so that each hole position on the workpiece 10 is aligned with the corresponding hole position penetration mechanism. The equipment is started, and the first hole position penetration mechanism 4 or the second hole position penetration mechanism 5 is operated successively, and the first hole position 20 or the second hole position 30 on the workpiece 10 is tested for penetration one by one. The present embodiment is described by detecting the penetration of the first hole 20, and the specific operation is as follows: the output end of the first telescopic member 41 drives the entire detection assembly (the first sleeve 42, the first guide shaft 43, the first needle 44, the first limit plate 45, and the first return member 46) to synchronously advance toward the direction of the first hole 20. When the first hole 20 is penetrated, the first needle 44 can smoothly pass through the first hole 20 on the workpiece 10; conversely, when the first hole 20 is not penetrated, the first needle 44 will be blocked in the first hole 20, and the first needle 44 applies pressure to the first return member 46. Under the action of the first return member 46, the first guide shaft 43 and the first limit plate 45 are moved toward the rear of the first sleeve 42, so as to avoid a hard collision between the first needle 44 and the first hole 20 that is not penetrated. At the same time, after the hole penetration test is completed, the first telescopic member 41 drives the entire detection assembly to move in a direction away from the first hole 20. Since the first needle 44 loses the resistance from the first hole 20, the first needle 44 will not apply pressure to the first return member 46. Therefore, under the action of the first return member 46, the first guide shaft 43 and the first limit plate 45 can be moved toward the front of the first sleeve 42 (i.e., toward the first hole 20) to achieve the reset of the detection assembly. By monitoring the change in the displacement of the detection assembly, the penetration status of multiple first holes 20 and multiple second holes 30 on the workpiece 10 can be known, and the detection results can be displayed on the display screen.

[0029] See also Figure 4In some embodiments, a first stop ring 47 is disposed in the inner cavity of the first sleeve 42, and the first return member 46 is a spring (the spring in the attached figure is only a simplified diagram of the outer diameter and length of the spring), one end of the spring abuts against the first needle 44, and the other end of the spring abuts against the first stop ring 47; the first guide shaft 43 passes through the middle of the first stop ring 47. Specifically, the first sleeve 42 is composed of two mutually fixed cylinders, and the inner cavity of the cylinder located in the front is contracted inward to form the first stop ring 47. When the first needle 44 is subjected to resistance, force is applied to the spring so that the spring is compressed in the inner cavity of the first sleeve 42, and the first needle 44 drives the first guide shaft 43 and the first stop ring 47 to move backward. When the first needle 44 is not subjected to force, the first needle 44 can smoothly pass through the first hole 20 or the second hole 30.

[0030] See also Figure 3 and Figure 4 In some embodiments, the first sleeve 42 is provided with a first sliding groove 421, the outer wall of the first needle 44 is connected with a first air pipe joint 441, the inner cavity of the first needle 44 is communicated with the first air pipe joint 441, and the first air pipe joint 441 is located in the first sliding groove 421. The first needle 44 is set to be hollow and form a gas channel, and high-pressure gas is introduced into the first air pipe joint 441 through a pipeline, so that the high-pressure gas is sprayed into the first hole position 20 or the second hole position 30 through the first needle 44, and the waste chips in the first hole position 20 or the second hole position 30 can be blown away, so that the hole penetration detection and the removal of waste chips in the hole position can be realized, killing two birds with one stone.

[0031] See also Figure 3 In some embodiments, a sensor fixing plate 422 is fixedly connected to the outer wall of the first sleeve 42, and a first sensor 423 is disposed on the sensor fixing plate 422. The first sensor 423 is used to sense the end of the first guide shaft 43. The first sensor 423 is electrically connected to the control mechanism, and the first sensor 423 is used to sense the position of the first guide shaft 43 or the first limit plate 45 to know whether the first needle 44 can pass through the first hole 20 or the second hole 30. Through the transmission of the signal, a prompt such as a hole on the No. 1 station is not through is displayed on the display screen.

[0032] See also Figure 3In some embodiments, a sensor fixing seat 31 is further provided on the first bracket 3, and two second sensors 32 are provided on the sensor fixing seat 31. The two second sensors 32 are arranged one above the other, and the two second sensors 32 are respectively used to sense the first needle 44 on the first hole position penetration mechanism 4 or the first needle 44 on the second hole position penetration mechanism 5. The second sensor 32 is used to detect whether the first needle 44 is broken. If broken, the relevant information such as the first needle 44 on the No. 1 station being broken is also displayed on the display screen through signal transmission.

[0033] See also Figure 2 and Figure 6 In some embodiments, the outer wall of the tool 2 is provided with guide blocks 21 of the same number as the first hole position penetration mechanism 4 or the second hole position penetration mechanism 5, and each of the guide blocks 21 is provided with a first guide hole 211 and a second guide hole 212. The first guide hole 211 is used for the first needle 44 on the first hole position penetration mechanism 4 to pass through; the second guide hole 212 is used for the first needle 44 on the second hole position penetration mechanism 5 to pass through. Since the first needle 44 is relatively long, the guide block 21 and the guide hole are provided to provide guidance for the first needle 44, so that the first needle 44 can be smoothly inserted into the first hole 20 or the second hole 30 with a smaller hole diameter.

[0034] See also Figure 1 , Figure 2 and Figure 6In some embodiments, the machine 1 is further provided with a plurality of third hole position penetration mechanisms 6, and the third hole position penetration mechanisms 6 include a third telescopic member, a third sleeve fixedly connected to the output end of the third telescopic member, a third guide shaft arranged in the inner cavity of the third sleeve, a third needle fixedly connected to the head end of the third guide shaft, a third limiting plate fixedly connected to the end of the third guide shaft, and a third return member sleeved on the third guide shaft; the third limiting plate is located on the outside of the third sleeve, and the third return member is used to drive the third needle, the third guide shaft and the third limiting plate to reciprocate along the length direction of the third sleeve; the third needle is toward the third hole position 40 corresponding to the workpiece 10. The structure of the third hole position penetration mechanism 6 is the same as that of the first hole position penetration mechanism 4 and the second hole position penetration mechanism 5, so the operating principle of the third hole position penetration mechanism 6 is also the same as that of the first hole position penetration mechanism 4 and the second hole position penetration mechanism 5. The difference between the two is that the output end of the third telescopic member in the third hole position penetration mechanism 6 is oriented in a different direction, specifically: when the output end of the third telescopic member is extended, the detection component is driven away from the workpiece 10, and when the output end of the third telescopic member is contracted, the detection component is driven close to the workpiece 10. Specifically, the third hole position penetration mechanism 6 also corresponds to the four third hole positions 40 on the workpiece 10, and is therefore also set to four.

[0035] See also Figure 2 and Figure 5 In some embodiments, the machine table 1 is further provided with a clamping mechanism 7, and the clamping mechanism 7 includes a first clamping telescopic member 71 with an output end facing the workpiece 10, a clamping connection block 72 connected to the output end of the clamping telescopic member, and a second clamping telescopic member 73 disposed on the clamping connection block 72 and with an output end facing the workpiece 10, and a pressing block 74 is disposed at the output end of the second clamping telescopic member 73, and the pressing block 74 is used to clamp the workpiece 10. After the workpiece 10 is placed on the tooling 2, the workpiece 10 needs to be clamped by the clamping mechanism 7 so that the workpiece 10 is firmly placed on the tooling 2. Specifically, the output end of the first clamping telescopic member 71 extends toward the direction of the workpiece 10, driving the clamping telescopic block 72 to move synchronously, until the second clamping telescopic member 73 is located above the workpiece 10, and then the output end of the second clamping telescopic member 73 extends, driving the pressing block 74 to move downward, so that the pressing block 74 clamps the workpiece 10. After the hole penetration detection is completed, the second clamping and retracting member 73 and the first clamping and retracting member 71 are reset to provide a clearance for the workpiece 10 to be unloaded.

[0036] See also Figure 5 In some embodiments, a soft pad 75 is further provided on the lower surface of the pressing block 74, and the soft pad 75 is used to contact the upper surface of the workpiece 10. The soft pad 75 is provided to protect the workpiece 10 and avoid hard extrusion.

[0038] In summary, the utility model sets a first hole penetration mechanism 4 and a second hole penetration mechanism 5 that are consistent with the number of holes on the workpiece 10, utilizes the extension or contraction of the output end of the first telescopic member 41 to drive the first needle 44 to move, and through the change in the position of the first needle 44, the penetration status of multiple first holes 20 and multiple second holes 30 on the workpiece 10 is known.
