Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the deflection instrument, and specifically refers to an automatic detection deflection instrument. BACKGROUND

[0002] The deflection instrument is used for measuring the radial runout error of the shaft part. The instrument uses two tips to position the shaft part, and measures the radial runout error of the shaft part by rotating the measured shaft part. The traditional deflection instrument can only detect the radial runout of the measured shaft part, and cannot detect the axial runout of the measured shaft part at the same time. Therefore, additional equipment is needed for detection, which is very troublesome.

[0003] Therefore, the deflection instrument capable of detecting the axial and radial runout at the same time is put into use, and the corresponding horizontal displacement mechanism and longitudinal displacement mechanism are used for moving the probe to detect the axial and radial runout, and the corresponding supporting device is used for adjusting the installation position of the detection equipment left and right and up and down to adapt to the detection of measured shaft parts of different sizes. The horizontal displacement mechanism and the longitudinal displacement mechanism are both slide rail and groove structures. The slide rail of the longitudinal displacement mechanism is only supported by a bolt, and the bolt is longitudinally installed. The repeated upward movement and resetting of the slide block will impact the bolt, which will cause the bolt to loosen and affect the detection of the axial runout. The screw rod assembly used for adjusting the position is mainly used for positioning the slide block on the screw rod assembly by means of clamp clamping, so as to adjust and fix the installation position of the detection equipment. However, the screw rod surface is easy to deform due to wear, which will affect the tightness of the clamp clamping. Especially the longitudinal adjusting screw rod assembly is also affected by the gravity of the slide block, so it is more likely to move downward due to the decrease of tightness, which will affect the detection of the axial runout.

[0004] Therefore, the automatic detection device for deflection instrument is designed to ensure the normal installation of the longitudinal displacement mechanism, and to effectively avoid the loosening and falling of the limiting bolt. The flexible pressing method of the rubber part is used to fix the screw rod assembly, so as to effectively avoid the wear problem caused by the traditional rigid clamping method, and further ensure the detection accuracy of the measured shaft part.

[0019] The utility model discloses the advantages of the following:

[0020] 1) the utility model discloses the cooperation of horizontal displacement mechanism, longitudinal displacement mechanism and detection assembly is used for the movable installation detection needle up and down and left and right, and the detection needle is abutted on the side wall of the measured part and moves with the measured part in axial and radial direction, drives the slider block seat of horizontal displacement mechanism or longitudinal displacement mechanism to move when moving, and detection piece moves and detects data in time, and the spring part of connecting detection piece is compressed, and the slider block seat of horizontal displacement mechanism or longitudinal displacement mechanism resets and continues to detect under the elastic potential energy of spring part, effectively realizes the synchronous detection of axial and radial two -way.

[0021] 2) This utility model uses a rhomboid connecting piece and a limiting piece to slide the slider seat and the sliding track. The V-groove ends of the slider seat and the sliding track are locked by limiting bolts, making the connection quick and easy, and allowing for the limited movement of the slider seat. However, this method, especially for the vertical movement of the slider seat in the longitudinal displacement mechanism, can easily cause the limiting bolt to loosen, affecting the detection of axial runout. Therefore, this utility model has a support mechanism installed below the limiting bolt of the longitudinal displacement mechanism to buffer and support the limiting bolt. The support mechanism includes a support mounting kit that moves vertically and vertically via a first elastic element. The kit strengthens the support of the limiting bolt and also has a shock absorption effect, effectively preventing the limiting bolt from loosening and falling off, ensuring detection accuracy. Furthermore, the compression of the first elastic element can cause the kit to move downward to create clearance, facilitating the locking and fixing of the limiting bolt and ensuring the normal installation of the longitudinal displacement mechanism.

[0022] 3) The support mechanism of this utility model not only includes the connecting kit and the first elastic element, but also a cylindrical part and a rod fixed below the kit by means of a fixing plate and bolts. The rod and the cylindrical part are inner and outer sleeved and connected to the first elastic element, which not only protects the first elastic element, but also limits the first elastic element and prevents the kit from affecting the support of the limiting bolt due to the displacement of the first elastic element, thereby improving the practical effect of this utility model.

[0023] 4) Both the axial detector and the radial detector of this utility model are high-precision pen-type displacement sensors. The high-precision pen-type displacement sensor contains a built-in spring and is detachably and fixedly installed on the mounting base and support base by a corresponding U-shaped part, which effectively realizes the reset of the probe and ensures the practical effect of this utility model.

[0024] 5) This utility model uses a combination of a horizontal and a vertical movement mechanism driven by a lead screw for adjustable and fixed installation of detection devices, making it suitable for the detection of parts of different sizes. A U-shaped connector is bolted and fixed to the guide screw frame, sleeved on the outside of the screw. When the end of the connector is not connected, the screw can smoothly pass through the connector and rotate. When the screw needs to be fixed, a small cylinder drives the locking part to move towards the connector. Because the middle of the locking part is equipped with an L-shaped closing part through a second elastic element, and the inner wall of the locking part and the outer wall of the connector are set as matching inclined surfaces, before the locking part moves into place, the closing part moves forward and presses against the outside of the rubber part set between the connecting parts of the connector. Thus, when the locking part moves into place and closes to the two connecting parts of the connector, it can ensure that the rubber part is squeezed and deformed only towards the side of the connector where the screw is set, and flexibly presses and fixes the screw, achieving the effect of squeezing and braking. This effectively avoids the wear problem caused by the traditional rigid clamping method and further ensures the detection accuracy of the tested parts.

[0025] 6) The compression piece of the utility model is connected with the locking piece through the second elastic piece, and the precision of the compression piece movement is improved through the cooperation of the guide cylinder and the connecting rod, so that the compression piece can be fixed on the outside of the rubber piece before the locking piece and the connecting piece are connected, so that the rubber piece can be directional extruded between the lead screw and the connecting piece when the locking piece and the connecting piece are connected, and the tightness of the locking is improved.

[0026] 7) The small cylinder of the utility model is used for accurately controlling the moving distance of the locking piece, and can effectively fix the locking piece, prevent it from rebounding and separating from the connecting piece, so as to improve the practical effect of the utility model, and further ensure the firmness of the locking.
