[0034] Please see Figures 2-4 The present invention provides a device for measuring the diameter of a lead screw in a plasticizing machine, comprising:

[0035] Main components: The main components include a base 11, a mounting slot 12, a support 13, and a dial indicator 14;

[0036] Mounting slots 12 are provided at both ends of the top of the base 11, support 13 is installed at the rear end of the top of the base 11, and dial indicator 14 is installed at the top of the support 13.

[0037] The base 11 is used to open the mounting slot 12. The operator places the lead screw between the lower probe 15 and the upper probe 16 and makes the lead screw and the measuring needle 17 make contact for measurement, so that the dial indicator 14 can display the measured data digitally.

[0038] All of the above parts are existing technologies;

[0039] Auxiliary components: The auxiliary components include telescopic rod 21, sleeve 22, auxiliary cylinder 23 and auxiliary groove 24;

[0040] The telescopic rod 21 is installed on both sides of the outer wall of the support 13, the sleeve plate 22 is fixedly connected to one end of the telescopic rod 21, the auxiliary cylinder 23 is fixedly connected to one end of the sleeve plate 22, and the auxiliary groove 24 is opened on the outside of the auxiliary cylinder 23.

[0041] Preferably, the auxiliary components also include a handle 25, a spring plate 26, a guide plate 27, a connecting block 28, a turntable 29, a through groove 210, and a guide groove 211;

[0042] Turntable 29 is rotatably connected to the inside of auxiliary cylinder 23, handle 25 is fixedly connected to the top of turntable 29, guide groove 211 is opened at the top of turntable 29, guide plate 27 is fixedly connected to the inside of auxiliary cylinder 23, spring plate 26 is slidably connected to the inner side of guide plate 27, connecting block 28 is fixedly connected to one end of spring plate 26, and through groove 210 is opened on the inner wall of auxiliary cylinder 23.

[0043] The auxiliary cylinder 23 is used to open the auxiliary groove 24, the turntable 29 is used to open the guide groove 211, the auxiliary cylinder 23 is used to open the through groove 210, the auxiliary groove 24 is used to provide through space for the rotating handle 25, the guide groove 211 is used to provide connecting space for the connecting block 28, and the guide plate 27 is used to provide sliding space for the spring plate 26.

[0044] With the auxiliary cooperation between the telescopic rod 21 and the sleeve plate 22, the rotating handle 25 can be rotated to drive the turntable 29 to rotate, so that multiple sets of spring plates 26 can slide at the same time.

[0045] Working principle: When the operator measures the lead screw;

[0046] First, after pulling the two sets of telescopic rods 21 to the appropriate place of use, by rotating the handle 25 that passes through the auxiliary groove 24, the handle 25 can drive the turntable 29 to rotate inside the auxiliary cylinder 23, and cause multiple sets of connecting blocks 28 to slide inside the guide groove 211. Thus, the spring plate 26 with connecting block 28 installed at one end can slide along the guide track of the guide plate 27 through the through groove 210 into the interior of the auxiliary cylinder 23.

[0047] Next, the two ends of the lead screw are inserted into one end of the sleeve plate 22 through the auxiliary cylinder 23. At the same time, the rotation formed on the handle 25 is released, so that the multiple sets of spring plates 26 can be reset through the through groove 210 under the influence of the elastic force, and the multiple sets of turntables 29 can limit and clamp the insertion end of the lead screw.

[0048] This step provides an auxiliary limit function for the lead screw during the measurement process, preventing the lead screw from shaking during measurement and affecting the accuracy of the measurement data.

[0053] The fixing groove 35 is opened inside the first auxiliary piece 32 and the second auxiliary piece 33. The fixing plate 36 is fixedly connected to the inside of the base 11. The limiting hole 37 is opened at one end of the fixing plate 36. The fixing groove 35 opened in the first auxiliary piece 32 and the second auxiliary piece 33 have different specifications and sizes.

[0054] The connecting groove 31 is used to provide sliding space for the first auxiliary piece 32 and the second auxiliary piece 33. The first auxiliary piece 32 and the second auxiliary piece 33 are used to open the fixing groove 35, and the fixing plate 36 is used to open the limiting hole 37.

[0055] Through the auxiliary cooperation between the connecting groove 31 and the first auxiliary piece 32, the first auxiliary piece 32 can slide while the fixing groove 35 and the mounting groove 12 opened in the first auxiliary piece 32 are assisted to be aligned and limited to the fixing plate 36.

[0056] Working principle: When the staff installs base 11;

[0057] First, by sliding the first auxiliary piece 32 inside the sliding connection groove 31, the first auxiliary piece 32 slides on the top of the fixing plate 36, which can align the fixing groove 35 and the mounting groove 12 inside the first auxiliary piece 32, and make the spring buckle 34 installed inside the first auxiliary piece 32 engage inside the limiting hole 37, so that the first auxiliary piece 32 and the fixing plate 36 can be connected in a limiting manner. At the same time, the mounting part is installed through the mounting groove 12 and the fixing groove 35 inside the first auxiliary piece 32.

[0058] Next, by sliding the second auxiliary piece 33 inside the sliding connection groove 31, the second auxiliary piece 33 can slide at the bottom of the fixing plate 36, and one end of the second auxiliary piece 33 can press the spring buckle 34 that is engaged inside the limiting hole 37, thereby releasing the limitation formed between the first auxiliary piece 32 and the fixing plate 36. At the same time, the spring buckle 34 installed inside the second auxiliary piece 33 and the limiting hole 37 are engaged and connected, so that the first auxiliary piece 32 can be reset under the influence of the elastic force, and the fixing groove 35 opened in the second auxiliary piece 33 and the mounting groove 12 are aligned and limited and connected with the fixing plate 36.

[0059] This step helps staff adjust and install the base 11 according to the specifications of the actual accessories and the groove at the installation location, increasing the flexibility and applicability of the base 11 installation.
