Technical Field
The utility model relates to the field of detection positioning equipment, in particular to a rear auxiliary frame detection positioning mechanism.
Background
The rear auxiliary frame welding assembly is provided with a control arm mounting bracket for welding the control arm and the like. The control arm mounting hole has multiple requirements on position degree, coaxiality, profile degree and the like, and the requirements need to be detected after welding is finished. The prior structure is generally a bolt fixed on a detection table for inserting the position of the auxiliary frame facing downwards after detection, and because the positions of the bolts are fixed, the position of the position aligning bolt can be inserted and detected only by vertically putting down the position of the rear auxiliary frame relative to the upper part of the bolt, thus the detection efficiency is low.
Disclosure of utility model
The utility model provides a rear auxiliary frame detection positioning mechanism capable of improving detection efficiency.
The utility model relates to a detection positioning mechanism for a rear auxiliary frame, which comprises a supporting seat and a base, wherein the supporting seat and the base are arranged on a detection table top and used for supporting the rear auxiliary frame, a bolt capable of being inserted into a positioning hole of the rear auxiliary frame in a vertical moving mode is arranged on the supporting seat in a penetrating mode, a supporting block is arranged on the side edge of the base, a top rod hinged with the base is arranged above the supporting block, one end portion of the top rod extends to the lower portion of the bolt, a rotary rod connected with the supporting block in a rotary mode is arranged in the middle of the top rod, and one end of the top rod can rotate relative to a hinged portion to jack the bolt through the rotary rod.
The utility model provides a rear sub vehicle frame detects positioning mechanism, run through the supporting seat setting, but the bolt of reciprocates under the effect of gravity, can hide and place in the supporting seat, place at the rear sub vehicle frame and four bights are fixed a position the back on detecting the mesa for the bolt is aimed at to the locating hole of rear sub vehicle frame, makes the one end jack-up bolt of ejector pin through rotatory dwang, and the locating hole of rear sub vehicle frame is detected to the bolt of being convenient for inserts, because the bolt is hidden and is placed in the supporting seat, therefore when placing the rear sub vehicle frame on detecting the mesa, need not to just can insert the position of hole site aiming at the bolt with the top perpendicular place of rear sub vehicle frame and insert and fix a position the detection, has improved detection efficiency.

Detailed Description
As shown in fig. 1-4, a rear auxiliary frame detection positioning mechanism comprises a supporting seat 1 and a base 2 which are arranged on a detection table top and used for supporting a rear auxiliary frame, a bolt 3 which can be inserted into a rear auxiliary frame positioning hole in a vertical moving mode is penetratingly arranged on the supporting seat, a supporting block 4 is arranged on the side edge of the base, a push rod 5 hinged with the base is arranged above the supporting block, one end portion of the push rod extends to the lower portion of the bolt, a rotary rod 6 which is connected with the supporting block in a rotary mode is arranged in the middle of the push rod, and one end of the push rod can rotate relative to a hinged portion to jack the bolt by rotating the rotary rod. The bolt that runs through the supporting seat setting, but reciprocate can hide under the effect of gravity and arrange in the supporting seat in, place at the back sub vehicle frame and four bights are fixed a position the back on detecting the mesa for the locating hole of back sub vehicle frame aligns the bolt, makes the one end jack-up bolt of ejector pin through rotatory dwang, and the locating hole of sub vehicle frame carries out the hole site detection after the bolt inserts of being convenient for, because the bolt is hidden and is arranged in the supporting seat, when placing the back sub vehicle frame on detecting the mesa, need not to put down the place of just can inserting the position of hole site alignment bolt perpendicularly with the top of the relative bolt of back sub vehicle frame and fix a position the detection, has improved detection efficiency.
The bolt is sleeved with a spring 7, and two ends of the spring are respectively propped against the inside of the supporting seat. The ejector rod enables the spring to be in a stretching state when the bolt is jacked up, and after detection is finished, the bolt can be quickly moved downwards to be hidden in the supporting seat under the elastic restoring effect of the spring, so that the bolt is prevented from being clamped in the positioning hole of the rear auxiliary frame.
Still install the sleeve 8 that supplies the bolt to pass in the supporting seat, telescopic lateral wall sets up spacing spout 801, is equipped with the spacing post 802 that follows the draw-in groove and remove on the bolt, can prevent that the bolt from too deep into in the locating hole of back sub vehicle frame.
The end of the ejector rod 5 opposite to one end of the bolt is provided with an upward protruding limit edge 501. Preventing the ejector rod from extending too long or too short to jack the bolt.
The ejector rod is hinged with the base through a rotating shaft 9, so that the ejector rod can rotate around the rotating shaft.
The rotary rod is connected with the supporting block in a rotary mode through threads, the rotary rod can enable the ejector rod and the supporting block to be close to each other, and then one end of the ejector rod is jacked up to be propped against the bolt and the bolt is jacked into the positioning hole of the rear auxiliary frame.
