The wrench 50 is sleeved on the adjusting rod 40 and can drive the adjusting rod 40 to rotate. The support pin 60 is disposed in the housing hole 21, the support pin 60 has a first end 61 and a second end 62 opposite to the first end 61, the first end 61 abuts against the adjustment lever 40, and the second end 62 is inserted into the first insertion hole 22 and the second insertion hole 31.

More specifically, the removable positioning device 100 further includes a bushing 70, the bushing 70 being positioned in the first through-hole 22 of the support plate 20 and sleeved over the second end 62 of the support pin 60. The number of the adjustment lever 40, the wrench 50, the support pin 60, and the bushing 70 is two.

The fixing plate 10, the supporting plate 20 and the positioning plate 30 are C-shaped. The cross-sectional area of the fixed plate 10 in the direction perpendicular to the axis is larger than the cross-sectional areas of the support plate 20 and the positioning plate 30 in the direction perpendicular to the axis. When installed, the stationary plate 10 faces the housing assembly, and the stationary plate 10 has a larger cross-sectional area such that the stationary plate 10 may abut the housing assembly.

The thickness of the support plate 20 in the direction parallel to the axis is greater than the thickness of the fixed plate 10 and the positioning plate 30 in the direction parallel to the axis.

The thickness of the positioning plate 30 can be adjusted according to actual requirements.

It should be noted that the supporting plate 20 and the fixing plate 10 are fixed by a fastener, and the positioning plate 30 and the supporting plate 20 are fixed by a fastener. The fastener is a bolt, but not limited thereto.

The wrench 50 is sleeved on the adjusting rod 40, and the adjusting rod 40 can be rotated by pulling the wrench 50.

Fig. 3 is a perspective view of the detachable positioning device shown in fig. 1 in an installed state, please refer to fig. 3 together, the detachable positioning device 100 is used in cooperation with a base assembly fixture, the base assembly fixture includes a pull rod 301, a mandrel 302, an expanding sleeve 303, a main shaft 304 and a tip 305 are further disposed on the processing machine, and the pull rod 301 and the tip 305 are respectively disposed at two ends of the mandrel 302. The main shaft 304 can drive the pull rod 301 and the mandrel 302, and the mandrel 302 and the expanding sleeve 303 are in taper fit, so that the expanding sleeve 303 can expand the inner hole of the base assembly 400.

When the stand assembly 400 needs to be machined, firstly, the detachable positioning device 100 is assembled, the fixing plate 10, the supporting plate 20 and the positioning plate 30 are sleeved on the main shaft 304, the supporting threads are pressed inwards by two hands and screwed out to eject the supporting nail, and the end face of the supporting nail is provided with a limit position to ensure that the positioning positions are consistent each time; the worker pulls the wrench 50 inwards with both hands to screw out the adjusting rod 40, the adjusting rod 40 ejects the supporting nail 60 out, the supporting nail 60 penetrates through the second through hole 31 of the positioning plate 30, the end face of the second end 62 of the supporting nail 60 can realize limiting, and the consistent positioning position is ensured every time. The base assembly 400 is well installed through the base assembly clamp, the fixing plate 10 faces the base assembly, and due to the positioning effect of the detachable positioning device 100, the base assembly 400 cannot move along with the expansion sleeve 303 in the tensioning process, so that the base assembly 400 is accurately positioned. After the base assembly fixture is adopted to clamp the base assembly 400, a worker pulls the wrench 50 outwards with both hands to screw the adjusting rod 40 tightly, the supporting nail 60 is separated from the adjusting rod 40, the supporting nail 60 shrinks by about 0.1mm under the action of internal force, and the gap can meet the requirement that the worker takes off the detachable positioning device 100. After the removable positioning device 100 is removed, the base assembly 400 may be machined.

It should be noted that, when the adjusting rod 40 is screwed out, the end face has a 1mm gap, and the tail parts of the adjusting rod 40 and the supporting nail 60 are designed to be round-head shapes, so that the contact area is reduced, the friction force and the pressing friction force of the end face of the adjusting rod 40 are reduced, and the manual operation is convenient for the worker to easily operate the adjusting rod with both hands outwards.

Because the inner hole of the base assembly 400 is a stator core, the length of the core is large, and in order to meet the tensioning requirement of the expansion sleeve 303, a proper positioning position needs to be calculated so that the expansion sleeve 303 can tension workpieces of all types, and the thickness dimension of the support plate 20 is finally determined;

because the entire removable positioning device 100 is convenient for the flat positioning of the base assembly 400, the removable positioning device 100 is placed on the machine tool fixture and is coaxial with the spindle 304, the fixing plate 10 is added for reducing the weight, and the semicircular diameter is matched with the outer diameter of the spindle 302 and can be directly installed.

As the base assembly 400 with multiple base numbers and lengths needs to be positioned, the positioning plate 30 capable of being replaced quickly is added, the fixing plate 10, the supporting plate 20 and the positioning plate 30 are designed in a three-section mode, the processing difficulty of the supporting nail holes is reduced, the coaxiality of the second through holes 31 of the positioning plate 30 and the through holes in the bushing 70 is ensured, and all product positioning can be met only by replacing different positioning plates 30.

Because the end surface plane and the inner spigot diameter are required to be processed by the stand assembly 400, a cutter needs to extend into the stand assembly 400 from the main shaft end for processing, the functions of end surface positioning and disassembling are realized by utilizing the adjusting rod 40 and the supporting nail 60, the adjusting rod 40 is controlled to screw and unscrew threads by matching with the manual wrench 50, the two threads are designed to rotate in the positive and negative directions, and the operation habit of workers is met.
