Description
Technical Field
[0001] The utility model belongs to the technical field of detection, and particularly relates to a detection device with an anti-deviation mechanism. Background Technique
[0002] During the mechanical processing production process, it is necessary to detect the processed parts to ensure that the processed parts meet the required standards. Among them, during the production process of a cylinder head similar to a hydraulic cylinder, surface flatness detection is required.
[0003] The existing detection device does not set an anti-deviation fixing mechanism for the cylinder head of the hydraulic cylinder during detection. Therefore, during detection, the cylinder head workpiece is prone to position deviation. After the position deviation, detecting again is likely to lead to a decrease in detection accuracy. For this reason, we propose a detection device with an anti-deviation mechanism. Content of the Utility Model
[0004] The purpose of the utility model is to provide a detection device with an anti-deviation mechanism to solve the problem that the existing detection device does not set an anti-deviation fixing mechanism for the cylinder head of the hydraulic cylinder during detection. Therefore, during detection, the cylinder head workpiece is prone to position deviation. After the position deviation, detecting again is likely to lead to a decrease in detection accuracy as mentioned in the above background technique.
[0005] To achieve the above object, the present utility model provides the following technical solutions: A detection device with an anti-deviation mechanism, including a detection pedestal, on which a detection frame is installed. A marking plate is fixedly installed on the upper surface of the detection pedestal. A slideway is formed on the side surface of the detection pedestal, and a sliding push plate is slidably installed in the slideway. The left end of the sliding push plate extends into the detection pedestal and is fixed with two oppositely arranged inclined plates. On the front and rear sides inside the detection pedestal, sliding matching plates are movably arranged. The sliding matching plates are provided with sliding channels for the inclined plates to slide. A connecting frame is fixedly installed on the upper surface of the sliding matching plate, and an anti-deviation clamping plate is fixedly installed at the top of the connecting frame. A strip-shaped channel for the connecting frame to move is formed on the upper surface of the detection pedestal. An extension plate is fixedly installed on the side surface of the detection pedestal, and a fixing screw is fixedly installed on the upper surface of the extension plate. A long strip slideway is formed on the sliding push plate. The fixing screw passes through the long strip slideway and is threadedly installed with a nut. A rotating plate is rotatably installed on the lower surface of the detection frame. An installation groove is formed on the lower surface of the rotating plate, and both side surfaces of the inner wall of the installation groove are rotatably installed with rotating shafts. One end of one of the rotating shafts is fixedly installed with a handle, and a lead screw is fixedly installed between the two rotating shafts. A movable block is threadedly installed on the outer surface of the lead screw and fits and slides on the inner wall of the installation groove. An outer cylinder is fixedly installed on the lower surface of the movable block. An inner rod is slidably installed in the inner wall of the outer cylinder. A sliding rod is slidably installed at the bottom end of the inner rod. Universal balls and installation sleeves are respectively fixedly installed at both ends of the sliding rod. A marking pen is inserted into the installation sleeve, and a bolt for pressing and fixing the marking pen is threadedly installed on the installation sleeve. A second spring is sleeved outside the sliding rod, and both ends of the second spring are fixedly connected with the inner rod and the installation sleeve respectively.
[0006] With the above scheme, by setting the anti-deviation clamping plate and using the movement of the sliding push plate in cooperation with the inclined plates and the sliding matching plates, the two anti-deviation clamping plates move synchronously and relatively, realizing the effective locking of the hydraulic cylinder cylinder head, and further ensuring that the detection process is not prone to deviation and dislocation, ensuring no deviation during detection, and effectively avoiding the problem of reduced detection accuracy caused by deviation and dislocation during detection. By setting the rotating plate in cooperation with the lead screw, the outer cylinder and the inner rod, the rotating plate rotates to achieve synchronous detection around. By rotating the lead screw to adjust the position, the position of the marking pen can be adaptively adjusted according to the inner diameter of the hydraulic cylinder cylinder head, and by adjusting the height in cooperation with the outer cylinder and the inner rod, it is suitable for detection at different height positions. In cooperation with the sliding rod, the second spring, the marking pen and the marking plate, when detecting the flatness of the inner wall of the hydraulic cylinder cylinder head, the marking pen can be used to draw a circle on the surface of the marking plate, which can more intuitively display the flatness.
[0007] As a preferred implementation manner, a plurality of rolling balls are installed on both the upper surface and the lower surface of the inclined plate, and the spherical bodies of the rolling balls cooperate with the inner wall of the sliding channel.
[0008] With the above solution, the arrangement of the rolling ball is used in combination with the inclined plate and the sliding channel, which can ensure better stability during the sliding movement between the inclined plate and the sliding mating plate, and effectively avoid the phenomenon that excessive friction affects the smooth movement.
[0009] As a preferred embodiment, a plurality of first springs and telescopic rods are fixed on the front and rear side surfaces of the inner wall of the detection pedestal, and the telescopic rods and the first springs are fixedly connected to the sliding mating plate at the corresponding positions.
[0010] With the above solution, by using the first spring in combination with the telescopic rod, the telescopic rod can support the movement of the sliding mating plate, making the movement of the sliding mating plate smoother and more convenient. When the two sliding mating plates approach each other, the first spring will be stretched and deformed. Therefore, when the fixation is released after processing, the elastic force of the first spring can be used to drive the sliding mating plate to quickly reset, improving the operation convenience.
[0011] As a preferred embodiment, a trapezoidal slider is fixedly installed on the upper surface of the rotating plate, and an annular sliding groove for the trapezoidal slider to slide is formed on the lower surface of the detection frame.
[0012] With the above solution, the trapezoidal slider is used in combination with the annular sliding groove, which can ensure better rotational stability of the rotating plate and is not prone to the phenomenon of shaking and falling.
[0013] As a preferred embodiment, a plurality of limiting blocks are fixed on the inner wall of the outer sleeve, and a plurality of limiting grooves for the limiting blocks to slide are formed on the outer surface of the inner rod.
[0014] With the above solution, the limiting blocks slide in the limiting grooves, which can limit the up and down movement of the inner rod and ensure good stability of the up and down movement of the inner rod.
[0015] As a preferred embodiment, a plug pin is inserted into the outer sleeve, and a plurality of insertion holes for the plug pin to be inserted are formed on the inner rod.
[0016] With the above solution, after the inner rod moves up and down to adjust the position, the plug pin and the insertion hole can be used to lock the position, and the locking structure is simple.
[0017] Compared with the prior art, the beneficial effects of the present utility model are:

Furthermore, it can ensure that the detection process is not prone to the phenomenon of deviation and dislocation, ensure no deviation during detection, and effectively avoid the problem that the detection accuracy decreases due to deviation and dislocation during detection;

By rotating the lead screw to adjust the position, the position of the marking pen can be adaptively adjusted according to the inner diameter of the hydraulic cylinder head. In addition, by adjusting the height in cooperation with the outer cylinder and the inner rod, it is suitable for detection at different height positions. When used in cooperation with a sliding rod, a second spring, a marking pen, and a marking plate, it can draw a circle on the surface of the hydraulic cylinder head inner wall with the marking pen during the flatness detection of the hydraulic cylinder head inner wall, and can more intuitively display the flatness.
