Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of measuring equipment auxiliary tools, and particularly relates to a probe connecting device capable of quickly adjusting the center of a probe. BACKGROUND

[0002] At present, when measuring camshafts or eccentric shafts and other shaft parts, the cam or eccentric has an angle requirement relative to the reference, which requires that the probe and the measured part be corrected to be in the same center position before measuring the angle. The probe connecting device of most detection equipment is integral, for example, in the structure disclosed in the Chinese invention application "CN117053686A Camshaft Axial Numerical Control Detection Method", there is still a gap of several microns when the probe (i.e. the measuring needle) reaches the vicinity of the shaft center of the measured part. At this time, it is very inconvenient to finely adjust the center of the probe (i.e. the measuring needle) to align with the shaft center of the measured part, and it is necessary to repeatedly adjust the detection equipment, which is time-consuming and low in efficiency. SUMMARY

[0003] In order to solve the above problems, the utility model provides a probe connecting device capable of quickly adjusting the center of a probe. The device can make the probe deviate to one side and approach the shaft center of the measured part by turning the adjusting bolts on both sides of the U-shaped support with a wrench, and the adjustment accuracy can reach within 5 microns. The specific technical scheme adopted is as follows: a probe connecting device capable of quickly adjusting the center of a probe, at least comprising a tray fixed on a detection equipment, a support connecting block, a U-shaped support, a probe seat and a probe being sequentially arranged in front of the tray, the support connecting block being fixedly connected with the front of the tray, the U-shaped support being integrally formed by a front plate, a rear plate and a connecting part located between the front plate and the rear plate, the cross section of the U-shaped support being in the shape of two "U"s connected as one and the openings of the two "U"s facing two sides, the rear plate of the U-shaped support being fixedly connected with the support connecting block, adjusting bolts being arranged on both sides of the U-shaped support, the head of the adjusting bolt being located in the front plate of the U-shaped support and the tail of the adjusting bolt being located in the rear plate of the U-shaped support, and the probe seat being fixedly connected with the front plate of the U-shaped support.

[0004] Moreover, the tray of the probe connecting device is fixedly installed with the detection equipment as a substantial whole.

[0005] Moreover, the fixing direction of the U-shaped support and the support connecting block is horizontal or vertical.

[0006] Moreover, the front plate of the U-shaped support is provided with a bolt head limiting hole and a through screw hole, and the rear plate of the U-shaped support is provided with a screw hole, so that the head of the adjusting bolt is located in the front plate of the U-shaped support and the tail of the adjusting bolt is located in the rear plate of the U-shaped support.

[0007] Moreover, the rear plate of the U-shaped support is fixedly connected with the support connecting block through a support locking bolt, and the head of the support locking bolt is all sunk into the rear plate of the U-shaped support.

[0008] Moreover, the measuring head connecting device is made of stainless steel, thereby ensuring the structural strength of the measuring head connecting device.

[0009] Compared with the prior art, the measuring head connecting device has the following beneficial effects:

[0010] 1. The cross section of the U-shaped support is in the shape of two "U" characters connected as a whole, and the openings of the two "U" characters face two sides. The head of the adjusting bolt is located in the front plate of the U-shaped support, and the tail of the adjusting bolt is located in the rear plate of the U-shaped support. When the adjusting bolts on the two sides of the U-shaped support are turned by a wrench, the distance between the front plate and the rear plate in the turned area is shortened, the measuring head is deviated to one side, and the center of the measuring head is finely adjusted. The precision can be controlled within 5 microns. The difficulty that the position of the measuring head must be repeatedly adjusted every time in the prior art is avoided.

[0011] 2. The front plate of the U-shaped support is provided with a bolt head limiting hole and a through screw hole, and the rear plate of the U-shaped support is provided with a screw hole. The head of the adjusting bolt is located in the front plate of the U-shaped support, and the tail of the adjusting bolt is located in the rear plate of the U-shaped support. Therefore, the distance between the front plate and the rear plate of the U-shaped support can be changed by turning the adjusting bolt.

[0012] 3. The rear plate of the U-shaped support is fixedly connected with the support connecting block through a support locking bolt. The head of the support locking bolt is completely sunk into the rear plate of the U-shaped support, so as to avoid that the support locking bolt hinders the distance adjustment space between the front plate and the rear plate, and at the same time, the support connecting block is ensured not to be loosened when running up and down or left and right.
