Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
At present, the size of a part is selected and checked by measurement and detection personnel due to the limitation of the placement position of the upper sealing sleeve. Before detection, the product needs to be manually aligned, and in the measuring process, a three-coordinate measuring machine needs to be manually operated for detection, so that the detection efficiency is low. As shown in figure 1, the invention relates to a self-centering clamping device for automatically detecting multiple sealing sleeves.

The tool support plays a role in integral support. The workpiece clamping mechanism and the pneumatic control element are matched for use, and the function of quickly and accurately centering and positioning the sealing sleeve is achieved.
In order to realize the purpose that the tool can clamp a plurality of sealing sleeves 11 at one time, the tool support is made into a square tray-shaped structure. The workpiece clamping mechanism is designed to be four-claw, and 9 pieces of workpiece clamping mechanisms are arranged in a matrix according to the stroke range of the three-coordinate measuring machine under the condition that the maximum data of the sealed sleeve workpiece is measured. Meanwhile, the distance between the two seal sleeves is designed according to the interference degree of the rotation angle of the measuring needle of the three-coordinate measuring machine during measurement of the seal sleeve workpiece, and 9 seal sleeves can be placed at a time under the condition that the measurement is not influenced.
The tool support is made of steel materials and comprises support legs 4, an installation panel 5, a shield 3 and the like. The supporting legs 4 are provided with three-coordinate measuring machine connecting holes, and after the tool is placed on the table board of the three-coordinate measuring machine, the tool and the platform of the three-coordinate measuring machine can be connected into a whole through fastening bolts, so that the tool is stable and reliable. The outer leakage parts of the mounting panel 5, the shield 3 and the like are effectively treated to prevent deformation after being used for a period of time. The mounting panel 5 and the shield 3 are connected by bolts. The workpiece clamping mechanism is made of aluminum alloy materials, and the sealing sleeve 11 is prevented from being scratched. The aluminum alloys are all subjected to oxidation treatment to prevent deformation.
All designs about the frock has handle 2, makes things convenient for two people to carry and places. The workpiece clamping mechanism can position the seal sleeve 11 by adopting a four-point method. The through hole of 4 phi 9 of 350 x 350 on the supporting leg 4 is fixedly connected with the M8 bolt hole on the three-coordinate measuring machine platform, the gas pipeline connected with the gas source is communicated with the pneumatic paw, and the gas pipeline is sequentially provided with a pressure regulating valve 8, a three-position four-way reversing valve 7 and a speed regulating valve 1. Meanwhile, 9 seal sleeve workpieces are placed on the self-centering pneumatic paw, the three-position four-way reversing valve 7 is rotated, and the four fingers can be adjusted to the opening position through the air channel system. The size of the clamping force of the self-centering pneumatic paw and the clamping speed are controlled by adjusting the air flow supply pressure and speed. The grasping and releasing movement of the self-centering pneumatic paw is completed by controlling the three-position four-way reversing valve 7, the self-centering positioning and clamping of the sealing sleeve are realized, and after the three-coordinate detection is completed, only the three-position four-way reversing valve 7 is controlled to release the paw, and the sealing sleeve workpiece is replaced.
The sealing sleeve belongs to a small-sized cylindrical thin-wall part, the key dimensions of the excircle and the height direction need to be detected according to detection requirements, the datum positioning of the sealing sleeve mainly passes through a central circular hole and a bottom surface, so that the central circular hole and the bottom surface of the sealing sleeve are considered for positioning, four pneumatic fingers of the pneumatic claw are simultaneously opened, the center of a circle of a sealing sleeve workpiece is automatically forced to coincide with the center of a circle of the pneumatic claw while the sealing sleeve workpiece is opened, the degrees of freedom of the sealing sleeve workpiece in six directions are limited, the tensile force of the pneumatic fingers is adjustable, and the workpiece is prevented from being deformed due to the fact that the sealing sleeve workpiece is not clamped or the clamping force is too large. Considering that the workpiece is a thin-wall part with the thickness of 4mm, the workpiece is easy to deform due to overlarge clamping force of the workpiece, and meanwhile, the parts are large in batch, so that the clamping is convenient and quick to take into consideration, and the working efficiency is improved. Through repeated comparison of the schemes, the scheme that the gas claw self-centering tensioning and the workpiece clamping force are adjustable is finally considered to meet the use requirement to the greatest extent. In order to ensure that each sealing sleeve can be accurately positioned on the clamping device, the processing and positioning requirements of the self-centering pneumatic paw and the flatness of the contact part of the bottom surface of the sealing sleeve are not more than 0.02mm, and the cylindricity of the cylinder formed by four pneumatic fingers is not more than 0.02mm, so that the requirement of accurate positioning of the sealing sleeve can be met. Meanwhile, the clamping device is periodically checked every year to prevent change, in order to ensure safe and reliable clamping, an operator can adjust the clamping degree of the clamping device through the pressure regulating valve 8, the speed regulating valve 1 and the like, and the damage to a sealing sleeve workpiece is reduced to the maximum extent.
