To achieve the above object, technical scheme is used by the utility model：A kind of long tubing parts groove fills away from measurement
Put, including depth gauge rule and extension bar, the left end of the extension bar are provided with stationary jaw, its right-hand member passes through link and the depth gauge rule
Blade tail end connects, and the center line of the extension bar is overlapped with the center line of the blade and keep level, the measurement of the depth gauge rule
Pedestal is connected with movable jaw, and the movable jaw is as the movement of vernier is driven by the measurement pedestal and is moved.
In the above-mentioned technical solutions, described extension bar is made up of rectangular tube with the end plate for being separately fixed at rectangular tube both ends.
In the above-mentioned technical solutions, described link includes connection body, briquetting and cushion block, the table before connecting body
Groove is opened up on face, the briquetting and cushion block are each provided in the groove, wherein, the cushion block is located at the bottom land of groove, described
Briquetting is located at the notch of the groove, and both match somebody with somebody merga pass Top fastening screw and housing screw by the blade afterbody pressure of depth gauge rule
Tightly.
In the above-mentioned technical solutions, described Top fastening screw through link body wall outer surface and with corresponding pressure
Block or cushion block threaded connection.
In the above-mentioned technical solutions, mounting groove, the measurement pedestal are opened up on described movable jaw along its length
Bottom stretch into the mounting groove and held out against by trip bolt.
In the above-mentioned technical solutions, described movable jaw and stationary jaw and measured cell wall contact surface are oblique
Face.
The beneficial effects of the utility model are：The utility model is passed through by the way that depth gauge rule and extension bar are linked together
Stationary jaw and movable jaw carry out positioning measurement, solve in the prior art that the two annular groove groove hearts are surveyed away from accurate on long pipe part
Amount problem, and measurement error control is within 0.05mm；In addition, movable jaw of the present utility model and stationary jaw are with being measured
Cell wall contact surface be inclined-plane, realize self-centering, avoid dimension chain conversion, improve the drawback such as machining accuracy；Meanwhile
The parts such as link of the present utility model, movable jaw, positioning claw are made of the good steel of rigidity, and rigid plane connects
Touch, it is reasonable in design, it is simple in construction, it is easy to use, it is easy to make, cost is cheap, reliable operation, and measurement accuracy is high.

Embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model：
Embodiment：Referring to Fig. 1 and 2, a kind of long tubing parts groove is described to connect away from measurement apparatus, including depth gauge rule and extension bar 4
The left end of bar 4 is provided with stationary jaw 2, and its right-hand member is connected by link with the tail end of blade 10 of the depth gauge rule, the extension bar
Center line is overlapped with the center line of the blade and keep level, the measurement pedestal of the depth gauge rule are connected with movable jaw, institute
Movable jaw is stated as the movement of vernier is driven by the measurement pedestal and is moved.
Described extension bar 5 is by rectangular tube and is separately fixed at the end plate 3 at rectangular tube both ends and forms, and to ensure end plate during making
Flatness.
Described link includes connection body 7, briquetting 8 and cushion block 9, and the connection body opens up groove on 7 preceding surface,
The briquetting and cushion block are each provided in the groove, wherein, the cushion block is located at the bottom land of groove, and the briquetting is positioned at described recessed
The notch of groove, both compress the blade afterbody of depth gauge rule with merga pass Top fastening screw and housing screw so that depth gauge rule is not
Shake.Described Top fastening screw passes through the wall outer surface of link body and connected with corresponding briquetting or cushion block screw thread
