In the present application, terms such as "first", "second", etc. are used to distinguish different features, and are not used to limit the present application. The above-mentioned applications may be interchanged under different operating conditions.

The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, the present application provides a part size detecting apparatus for a production line, the detecting apparatus including: a frame 10, the frame 10 being slidably provided with a sliding seat 102, the sliding seat 102 being provided with a sensor 101; a driver 11, the driver 11 including a rotatable driving lever 111; and a conversion mechanism provided between the drive lever 111 and the slide block 102 for converting the rotation of the drive lever 111 into the reciprocating slide of the slide block 102; as shown in fig. 2, the conversion mechanism includes: a first link 21, a first end 211 of which 21 is hinged to an end of the driving lever 111; and a second link 22, wherein a first end 221 of the second link 22 is elastically connected to the first link 21, and a second end 222 of the second link 22 is hinged to a fixed rod 23, and the fixed rod 23 is fixedly connected to the sliding seat 102.

Conventionally, when a detection device with a sensor enters a detection position from a standby state, since the motion of a detection device in the moving process is simple and direct, the sensor is likely to be in hard contact or rigid contact with a detected part when entering the detection position, and thus the sensor may be damaged, and the detection result may be affected.

According to the technical scheme of the application, the driver 11 transmits power through the switching mechanism, so that the sensor 101 on the detection device is subjected to elastic action when entering the detection position, the detection device (particularly the sensor) can be protected to a certain extent, and hard contact or rigid contact with the detected part is avoided. In addition, during the whole action process of the sliding seat 102, due to the elastic design of the transmission line, the effect of soft buffering can be realized, so that the adverse effect on the sensor is avoided.

As shown in fig. 1, the frame 10 is slidably provided with a sliding seat 102, so that the sliding seat 102 with the sensor 101 can perform a reciprocating sliding motion relative to the frame 10, thereby enabling the sensor 101 of the detection device to approach or depart from the tested component according to the detection requirement. The matching mode of the sliding seat 102 and the frame 10 may include a sliding rail matching mode, a shaft sleeve matching mode, and the like according to different practical working conditions. As shown in fig. 1, the frame 10 preferably has a slide guide 103, and the slide base 102 is slidably disposed on the slide guide 103, and the slide base 102 is slidably engaged with the frame 10 through the slide guide 103.

In order to accurately display the working state of the detection device, as shown in fig. 1, at least one position detector 104 is provided on the frame 10 for detecting the position of the sliding seat 102 on the sliding guide 103. As shown in fig. 1, the sliding base 102 is preferably provided with a sensing head that can be detected by the position detector 104. In the case where the stroke of the slide base 102 with respect to the slide rail 103 is fixed, the number of the position detectors 104 is preferably 2, and the position detectors are respectively provided at the extreme positions of both ends of the frame 10 in the direction of the slide rail 103, and detect whether the slide base 102 is slid in place. The position detector 104 may be a proximity switch or other type of detector, such as a laser range finder or the like.

The actuator 11 is a rotary actuator, and a drive lever 111 of the actuator 11 can be rotated. The rotation of the drive lever 111 is converted into the reciprocating sliding of the slide holder 102 by the conversion mechanism. As shown in fig. 1, since the rotary driver 11 is used, it is possible to avoid excessive dependence on the installation space in the reciprocating direction, which has conventionally been done with linear driving. In the above embodiment, the rotary actuator 11 may be disposed above or below the sliding direction of the sliding base 102, so that the installation space can be adjusted appropriately. That is, the rotation driver provides power to provide a more flexible installation method for the detection device, so that the space utilization rate and the installation convenience of the detection device can be improved.

The conversion mechanism is provided between the drive lever 111 and the slide holder 102, and when the drive lever 111 rotates, the elastic power transmission of the conversion mechanism converts the power into a force for reciprocating the slide holder 102.

As shown in fig. 2, the two ends of the conversion mechanism are the first end 211 of the first link 21 and the second end 222 of the second link 22. The rotation of the driving rod 111 drives the first end 211 to move, so as to elastically drive the first end 221 of the second connecting rod 22 to move, the second connecting rod 22 drives the sliding seat 102 fixedly connected with the fixing rod 23 through the hinge joint with the fixing rod 23, and the purpose of enabling the sliding seat 102 to slide back and forth along the rack 10 under the driving of the rotary driver 11 is further achieved. The elastic connection between the first connecting rod 21 and the second connecting rod 22 realizes the elastic power transmission. The elastic connection between the first link 21 and the second link 22 can be achieved in various ways, for example, the two can be directly connected by a connecting member made of elastic material (such as a rubber link). In the drawings of the present application, however, a preferred elastic connection is provided, and the following description will focus on the illustrated embodiments.

As shown in fig. 3 and 4, the first rotation axis L1 of the driving lever 111, the second rotation axis L2 of the hinge between the first link 21 and the driving lever 111, and the third rotation axis L3 of the hinge between the second link 22 and the fixing lever 23 are parallel to each other.

As shown in fig. 4, the first rotation axis L1 is a central axis of the rotation shaft of the driving lever 111 of the above-mentioned rotary driver, the second rotation axis L2 is a central axis of rotation where the driving lever 111 is hinged to the first end 211 of the first link 21, and the third rotation axis L3 is a central axis of rotation where the second end 222 of the second link 22 is hinged to the fixing lever 23. In order to smoothly realize the transmission relationship, the first rotation axis L1, the second rotation axis L2, and the third rotation axis L3 are parallel to each other. Besides, the angular relationship among the first rotation axis L1, the second rotation axis L2, and the third rotation axis L3 may be set to other angles according to the needs of actual working conditions, for example, a planar hinge is changed to a spherical hinge.

As shown in fig. 1, in the process of converting the force by the conversion mechanism, the conversion mechanism is also affected by the inertia force when the slide holder 102 is started or stopped, in addition to receiving the force of the drive rod 111. Therefore, in a preferable case, the relative movement of the first end 221 of the second link 22 with respect to the first link 21 in two opposite directions of the axial direction is buffered by the elastic member. In other words, when the first end 221 of the second link relatively moves in the horizontal left direction shown in fig. 2 with respect to the first link 21, and also when relatively moves in the horizontal right direction, an elastic force acts between the first link and the second link. With the structural design of this embodiment, a good resilient cushioning effect can be achieved regardless of the direction of movement of the slide shoe 102 as shown.

As shown in fig. 2, it is preferable that one of the first link 21 and the second link 22 is a hollow cylinder, and the other of the first link 21 and the second link 22 slidably extends into the cylinder, and an elastic member is provided in the cylinder. Preferably, the first link 21 is a hollow cylindrical member, and the first end 221 of the second link 22 is slidably inserted into the first link 21 through the opening of the second end 212 of the first link 21. It is to be understood that although the first link 21 is a cylindrical member and the second link 22 is a rod-shaped member in the illustrated embodiment, the present application is not limited thereto, and according to another embodiment, the second link 22 may be designed as a cylindrical member and the first link 21 may be inserted as a rod-shaped member into the cylindrical member of the second link. These variants are all designed to achieve the purpose of elastic connection between the first link 21 and the second link 22, and all fall within the scope of protection of the present application.

The elastic member provided in the cylinder may have various forms, and may be, for example, an effect of elastic buffering using liquid or gas. In a preferred embodiment, however, the resilient member may be a spring member, as shown.

As shown in fig. 2, the inner wall of the opening of the second end 212 of the first link 21 is provided with a first flange 213, and the second link 22 extends through the first flange 213; the part of the second connecting rod 22 extending into the first connecting rod 21 is provided with a second flange 223; wherein an elastic member is disposed between the first flange 213 and the second flange 223. Wherein, the elastic component can be 1 or more. When there is one elastic member, one end of the elastic member is disposed at the first flange 213 and the other end is disposed at the second flange 223. When there are a plurality of elastic members, separate elastic members may be respectively disposed between the first flange 213 and the second flange 223, and between the second flange 223 and the hollow cavity bottom 214. The elastic member is preferably a spring 30, and the spring 30 is sleeved on the second link 22 and elastically pressed between the first flange 213 and the second flange 223 to play a role of buffering between the first link 21 and the second link 22.

As shown in fig. 1 and 2, it is preferable that one of the first link 21 and the second link 22 is provided with a proximity switch, and the other is provided with a sensing head opposite to the proximity switch for detecting whether the spring 30 is compressed. The proximity switch and the sensor head are naturally attached to each other by the elastic force of the spring 30. In the working state, when the sliding seat 102 is subjected to resistance during sliding or interferes with a workpiece to be measured during measurement, the spring 30 is compressed. Proximity switch and inductive head separation this moment, proximity switch feedback information to make operating personnel can in time receive detection device's alarm information, and then improved this spare part size detection device's security and reliability.

The drive rod 111 may rotate 360 degrees depending on various embodiments or operating conditions. However, in order to facilitate the reciprocating sliding of the sliding seat, it is preferable that the rotation range of the driving rod 111 is less than 360 degrees, that is, the driving rod 111 performs the reciprocating movement of the sliding seat through the swinging motion.

As shown in fig. 3 and 4, the driving lever 111 has a first rotation limit position X1 and a second rotation limit position X2 angularly displaced by 0 to 180 degrees and can reciprocally swing between the first rotation limit position X1 and the second rotation limit position X2, thereby reciprocally sliding the sliding seat 102 between the first sliding limit position H1 and the second sliding limit position H2. The angular displacement is an angular range of an arc of movement about the first rotation axis L1 during rotation of the drive lever 111. When the driving lever 111 is reciprocally swung between the first rotation limit position X1 and the second rotation limit position X2, the slide holder 102 is reciprocally slid between the first slide limit position H1 and the second slide limit position H2 by the switching mechanism.

The angular displacement of the driving lever 111 as described above is preferably 180 degrees between the first rotational limit position X1 and the second rotational limit position X2. As shown in fig. 3 and 4, in the first and second rotational limit positions X1 and X2, the first, second, and third rotational axes L1, L2, and L3 are all coplanar with one another; while in the non-extreme position the three axes of rotation are not in the same plane. As shown in fig. 4, in the first rotational limit position X1, the second rotational axis L2 is located between the first rotational axis L1 and the third rotational axis L3, when the sliding seat 102 is in the first sliding limit position H1. As shown in fig. 3, in the second rotation limit position X2, the first rotation axis L1 is located between the second rotation axis L2 and the third rotation axis L3, and the sliding seat 102 is at the second sliding limit position H2. The change through actuating lever 111 rotation angle drives the slip of sliding seat 102, compares and mostly is simple linear drive in traditional detection device, and this application scheme has very big promotion in the utilization ratio in space.

As can be seen from the above description, the driver 11 transmits power through the elastic power transmission path, so that the sensor 101 on the detection device is subjected to elastic action when entering the detection position, so as to protect the detection device (especially the sensor) to some extent and avoid hard contact or rigid contact with the detected component. In addition, during the whole action process of the sliding seat 102, due to the elastic design of the transmission line, the effect of soft buffering can be realized, so that the adverse effect on the sensor is avoided.

The preferred embodiments of the present application have been described in detail above, but the present application is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present application within the technical idea of the present application, and these simple modifications all belong to the protection scope of the present application.

It should be noted that, in the foregoing embodiments, various features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various possible combinations are not described in the present application.
