Detailed Description
For a clearer understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings and examples.
Fig. 2 and 3 show an exemplary embodiment of a device for synchronously and rapidly measuring the perpendicularity of two end surfaces of a piston part according to the present invention, which is a piston part having a relatively complex shape, such as a piston part used in a hydraulic damping system of an automobile. The target part 5 requires the rod part as a reference (reference surface 51), the perpendicularity of the upper end surface (first surface to be measured 52) has a requirement (for example, 0.05 mm), and the perpendicularity of the lower end surface (second surface to be measured 53) also has a requirement (for example, 0.15 mm), so that the dimension precision is high, the dimension precision is critical, the subsequent assembly is affected, real-time monitoring measurement is required in the production process to ensure qualification, and the traditional measurement method cannot meet.
The normal measuring operation state of a preferred embodiment of the synchronous rapid measuring device for verticality of two end surfaces of a piston part according to the present invention shown in fig. 1 corresponds to the verticality measuring operation of two end surfaces of a target part 5 shown in fig. 2 and 3. The device main body comprises a base 1, and a limiting module 2, a first measuring module 3 and a second measuring module 4 which are fixedly arranged on the base 1, wherein after the base 1 is fixedly arranged on a stable platform, the limiting module 2 is used for limiting the target part 5 axially and radially, and the target part 5 is limited to perform circumferential rotation movement only at a preset measuring position, so that the first measuring module 3 and the second measuring module 4 can respectively measure a first surface to be measured 52 and a second surface to be measured 53 of the target part 5 at the same time.
The limiting module 2 comprises a limiting bracket 21 fixedly installed on the base 1, and a supporting wheel set 22, a clamping wheel 23 and a limiting baffle 24 which are respectively installed on the limiting bracket 21. The support wheel set 22 comprises a first support wheel and a second support wheel for matching and bearing the target part 5, and in use, the first support wheel and the second support wheel are in direct contact with the reference surface 51 of the target part 5, at least one of the first support wheel and the second support wheel is connected with the driving mechanism 25 and is driven to rotate by the driving mechanism 25, and further friction force is formed by contact between the non-smooth surface and the reference surface 51 of the target part 5 to drive the target part 5 to perform circumferential rotation movement. Preferably, the drive mechanism 25 may be selected as a manual drive wheel or a motor drive mechanism or a combination of both; further preferably, the driving mechanism 25 can drive the first supporting wheel and the second supporting wheel to synchronously and co-rotate through conventional transmission modes such as belt transmission, gear transmission and the like so as to better drive the target part 5 to rotate. The clamping wheel 23 is swingably connected to the limiting bracket 21 through a first spring (not shown in fig. 1) and the swing arm 231, preferably, the first spring may be a torsion spring disposed at a position of a connecting shaft between the swing arm 231 and the limit, and the clamping wheel 23 provides an acting force to clamp the reference surface 51 of the target part 5 through the first spring, so as to provide complete radial limit to the target part 5 in cooperation with the support wheel set 22, and ensure stable axial position of the target part 5 in the measuring position. It is easy to understand that the clamping force provided by the first spring should be appropriate, so that the target part 5 is prevented from shaking when the target part rotates circumferentially due to too small acting force and insufficient limit, and meanwhile, the target part 5 is prevented from being influenced to rotate due to too large acting force.
The limiting baffle 24 abuts against the end face 54 of the non-to-be-measured surface of the target part 5, and provides axial limiting of the direction of the end face 54 of the non-to-be-measured surface to the target part 5. Preferably, the limit baffle 24 is installed on the limit bracket 21 in an adjustable manner in the axial direction, and the adjusting device can adapt to target parts 5 with different sizes to measure in a certain range. It is further preferred that the clamping wheel 23 is mounted axially adjustably on said swing arm 231 to provide a range of selectable clamping position adjustment of the target part 5 to provide better rotational balance of the target part 5.
The first measuring module 3 comprises a first measuring bracket 31 fixedly arranged on the base 1, a first measuring tool 32 arranged on the first measuring bracket 31 and a first measuring head 33 connected with the first measuring tool 32, wherein the first measuring head 33 is matched with a first surface to be measured 52 contacting the measuring target part 5, and the first measuring head 33 obtains perpendicularity data of the first surface to be measured 52 by continuously contacting the first surface to be measured 52 in the circumferential rotation process of the target part 5. The second measuring module 4 comprises a second measuring bracket 41 fixedly arranged on the base 1, a second measuring tool 42 arranged on the second measuring bracket 41 and a second measuring head 43 connected with the second measuring tool 42, wherein the second measuring head 43 is matched with a second surface 53 to be measured, which is contacted with the measurement target part 5, and the second measuring head 43 obtains perpendicularity data of the second surface 53 to be measured by continuously contacting the second surface 53 to be measured in the circumferential rotation process of the target part 5; in particular, the second measuring head 43 is further connected to the second measuring bracket 41 through a second spring 44, and applies an axial force to the second surface 53 to be measured through the second spring 44, so as to form a sufficient axial limit on the target part 5 in cooperation with the limit stop 24. It will be readily appreciated that since the second measuring head 43 needs to exert an axial force on the target part 5 during measurement, the shape of the second measuring head 43 may be preferred to a measuring head having a large contact area. Preferably, the first gauge 32 and the second gauge 42 may use digital display, and are connected to a control host (computer end), and transmit measurement data to the control host.
The invention also relates to a method for measuring verticality by using the measuring device, which comprises the following steps:
S1, placing a reference surface 51 of a target part 5 to be measured on a supporting wheel set 22, axially moving the target part 5 to enable an end surface 54 of a non-measured surface of the target part 5 to abut against a limit baffle 24, enabling a first measuring head 33 to be matched with a first measured surface 52 of the target part 5, enabling a second measuring head 43 to be matched with a second measured surface 53 of the target part 5, and enabling the second measuring head 43 to abut against the second measured surface 53 of the target part 5 through the acting force of a second spring 44 to provide axial limit for the target part 5.
S2, releasing the clamping wheel 23 to enable the clamping wheel 23 to contact the reference surface 51 of the target part 5, and simultaneously enabling the clamping wheel 23 to clamp the reference surface 51 of the target part 5 through the first spring acting force, and combining with the supporting wheel set 22, providing radial complete limit for the target part 5.
S3, the driving mechanism 25 drives the supporting wheel set 22 to rotate, the supporting wheel set 22 drives the target part 5 to rotate circumferentially through friction force, and meanwhile the first measuring tool 32 and the second measuring tool 42 record perpendicularity data of the first surface to be measured 52 and the second surface to be measured 53 relative to the reference surface 51 respectively.
S4, the first measuring tool 32 and the second measuring tool 42 transmit perpendicularity data of the first surface to be measured 52 and the second surface to be measured 53 relative to the reference surface 51 to a control host, and the control host judges whether the target part 5 is qualified or not according to the preset detection standard matching perpendicularity data. The qualified products can be transferred to a qualified stock bin, and the unqualified products are put into a waste stock bin; when the measurement result is more ideal, the production state can be maintained, and when the measurement result is more unqualified or deviates to the tolerance limit, the equipment parameters or equipment tools can be adjusted, so that the rejection rate of parts can be obviously reduced.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present invention should be included in the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
