Detailed Description

As described in the background, when the probe assembly/negative pressure assembly is installed, the positions of the plurality of groups of probe assemblies/negative pressure assemblies on the chemical dividing and distributing device need to be initially positioned. In a common positioning mode, two positioning pins arranged on a movable middle frame of the chemical composition equipment are used for positioning, specifically, the positioning tool comprises a bottom plate and a mounting plate fixed on the bottom plate, the mounting plate and the bottom plate are of a whole plate structure, pin holes corresponding to the two positioning pins on the movable middle frame are arranged on the bottom plate, two rows of positioning pins are arranged on the mounting plate, each positioning pin in the same row of positioning pins corresponds to pin holes of the same end of a plurality of groups of probe assemblies/negative pressure assemblies along the length direction respectively, and the positioning pins corresponding to the same probe assemblies/negative pressure assemblies in different rows are in one group. The two pin holes of the bottom plate are in one-to-one correspondence with the two positioning pins of the movable middle frame, and then the movable middle frame can drive the positioning tool to move towards the multiple groups of probe assemblies/negative pressure assemblies, so that the multiple groups of positioning pins on the two mounting plates respectively extend into the pin holes at the two ends of the multiple groups of probe assemblies/negative pressure assemblies along the length direction.

However, when another type of chemical composition equipment is produced, the intervals between the groups of probe assemblies/negative pressure assemblies are different, so that the positioning tool needs to be prepared again according to the whole of the chemical composition equipment after the mold change, and the cost is high.

On the other hand, the distance between the positioning holes at two ends of the multiple groups of probe assemblies/negative pressure assemblies is changed, and as the positions of the pin holes on the bottom plate of the positioning tool and the positions of the two mounting plates are unchanged, the positioning tool cannot be matched with the positioning pins of the movable middle frame in a positioning manner and then is mounted on the movable frame, and the distance between the same groups of positioning pins cannot be matched with the distance between the multiple groups of probe assemblies/negative pressure assemblies, in other words, the positioning tool is difficult to be matched with the chemical composition equipment after the mold change.

Based on the above, the utility model discloses a positioning device which comprises a supporting mechanism and two positioning mechanisms. One of the two positioning mechanisms is arranged at two ends of the supporting mechanism along the first direction; the positioning mechanism comprises a detachable positioning assembly, the positioning assembly comprises a plurality of second positioning structures, and at least two second positioning structures are distributed along a second direction.

The two first adjusting members 110 can be locked to or unlocked from the first guide bar 120 by the locking members, and the two second adjusting members 210 can be locked to or unlocked from the second guide bar 230.

Illustratively, as shown in fig. 3, the second adjusting member 210 is provided with a second locking member, and is unlocked by the second locking member, so that the second adjusting member 210 slides relative to the second guide bar 230. The second locking member may include a second hoop 211 and a second wrench 212, where the second hoop 211 is sleeved on the outer circumference of the second guide rod 230 and is connected to the second adjusting member 210, the second wrench 212 is disposed on the second hoop 211, and the second wrench 212 is used for controlling the second hoop 211 to tighten or loosen the second guide rod 230 so as to limit the sliding of the second adjusting member 210 relative to the second guide rod 230, or enable the second adjusting member 210 to slide relative to the second guide rod 230. It can be appreciated that when the second wrench 212 is pulled to a state that the second hoop 211 is tightly held by the second guide rod 230, the second adjusting member 210 is in a locked state and cannot slide relative to the second guide rod 230, and when the second wrench 212 is pulled to a state that the second hoop 211 is released from the second guide rod 230, the second adjusting member 210 is in an unlocked state and can slide relative to the second guide rod 230. The arrangement of the second anchor ear 211 and the second wrench 212 advantageously limits the position of the second adjusting element 210 on the second guide bar 230, so that the distance between the two second adjusting elements 210 is kept constant after the two second adjusting elements 210 have been adjusted to the desired position.

For example, as shown in fig. 5, the first adjusting member 110 is provided with a first locking member, and the first adjusting member 110 is unlocked by the first locking member, so as to slide relative to the first guide rod 120. The first locking member includes a first hoop 111 and a first wrench 112, the first hoop 111 is sleeved on the outer periphery of the first guide rod 120 and is connected to the first adjusting member 110, the first wrench 112 is disposed on the first hoop 111, and the first wrench 112 is used for controlling the first hoop 111 to tighten or loosen the first guide rod 120 so as to limit the first adjusting member 110 to slide relative to the first guide rod 120 or enable the first adjusting member 110 to slide relative to the first guide rod 120. It can be appreciated that when the first wrench 112 is pulled to a state of holding the first anchor ear 111 tightly to the first guide rod 120, the first adjusting member 110 is in the locked state and cannot slide relative to the first guide rod 120, and when the first wrench 112 is pulled to a state of releasing the first anchor ear 111 to the first guide rod 120, the first adjusting member 110 is in the unlocked state and can slide relative to the first guide rod 120. By the arrangement of the first anchor 111 and the first spanner 112, it is advantageous to define the positions of the two first adjustment members 110 on the first guide bar 120, thereby defining the spacing between the two first adjustment members 110.

In the process that the first positioning pin stretches into the mounting hole 2221, the ball head of the ball plunger is extruded into the threaded hole 2212 positioned in the first positioning piece by the side wall surface of the mounting hole 2221 until the first positioning pin stretches into a clamping groove of the ball head of the ball plunger corresponding to the side wall surface of the mounting hole 2221, and the first positioning pin elastically moves out of the threaded hole 2212 positioned in the first positioning pin under the condition of no external force extrusion and is clamped in the clamping groove so as to limit the first positioning pin in the mounting hole 2221, so that the first positioning pin is detachably connected with the mounting hole 2221. When the first positioning pin needs to be removed, the first positioning pin can be pulled out of the mounting hole 2221, and the ball of the ball plunger is extruded into the threaded hole 2212 positioned in the first positioning pin again under the action of external force, so that the first positioning pin can be separated from the mounting hole 2221.
