Description

Technical Field

[0001] This application relates to the field of straightness testing of machine barrel inner bores, and more particularly to a device for testing the straightness of machine barrel inner bores. Background Technology

[0002] Traditional barrel bore straightness testing devices require the signal receiving probe to be located within a limited space to acquire laser signals. The probe's position should ideally be at the center of the barrel bore, currently determined by the contact between a pin on the support carriage and the barrel's inner wall. However, determining the bore's center position through two generatrices formed by the pin's contact with the inner wall results in a non-representative center location. Utility Model Content

[0003] To address the aforementioned issues, this application provides a device for detecting the straightness of the inner bore of a barrel. The device is placed on a trolley, and a motor is controlled by a remote control. The motor works in conjunction with a gear, which drives the signal receiving device to rotate, ensuring that the signal receiving probe remains in contact with the inner wall of the barrel, thus achieving 360° detection of the straightness of the inner bore.

[0004] This invention aims to provide an automated device capable of 360° omnidirectional sampling. Within the range of the inner bore of the barrel, the probe is always in contact with the inner bore of the barrel, receiving laser signals in real time. By determining the center position of the inner bore of the barrel through multiple points, the detection accuracy and efficiency are greatly improved.

[0005] According to one aspect of this application, a device for detecting the straightness of the inner bore of a barrel is provided, comprising a signal receiving device and a trolley;

[0015] The large gear 2-3 is connected and fastened to the rotating sleeve 2-4 by four M6×25 screws. The rotating sleeve 2-4 is transitionally fitted with the deep groove ball bearing 2-5, and the deep groove ball bearing 2-5 is transitionally fitted with the support 3-1, so that the motor 2-1 drives the rotating mechanism to rotate.

[0016] The linkage device 4 includes a connecting sleeve 4-1, a first connecting rod 4-2, a rotating shaft 4-3, a locking adjustment mechanism 4-4, a second connecting rod 4-5, a locking support mechanism 4-6, and a magnet 4-7;

[0017] The rotating shaft 4-3 is used in conjunction with the rotary sleeve 2-4. The rotary sleeve 2-4 has a semi-circular groove with milled stops at both ends of the groove to axially position the rotating shaft 4-3.

[0018] After the first connecting rod 4-2 passes through the rotating shaft 4-3, it is axially positioned by a set screw. At this time, the first connecting rod 4-2 can rotate around the rotating shaft 4-3. The right end of the first connecting rod 4-2 is connected to the connecting sleeve 4-1 by an M6×10 screw. The lower end of the M6×10 screw is connected to the large gear 2-3 by a tension spring. At this time, the connecting rod device 4 can rotate synchronously with the rotating mechanism 2.

[0019] The left end of the first connecting rod 4-2 is connected to the second connecting rod 4-5 through a locking adjustment mechanism 4-4;

[0020] After the left end of the second connecting rod 4-5 is connected to the locking support mechanism 4-6, the magnet 4-7 is fastened to the locking support mechanism 4-6. The signal receiving probe 5 is placed on the magnet 4-7. At this time, the signal receiving probe 5 can be kept in contact with the inner wall of the barrel at all times to collect the detection signal.

[0021] Select the appropriate carriage according to the different inner diameter of the barrel, so that the carriage is in the appropriate position in the inner diameter of the barrel.
