[0002] When measuring ordinary tools with a presetting instrument, the center line of the lens and the projection lamp is fixedly perpendicular to the axis of the spindle. This is completely satisfied when measuring tools such as drills, reamers, and boring tools. During the processing of workpieces, the auxiliary time for workpiece loading and unloading, tool adjustment, etc. accounts for a quite large proportion of the processing cycle. Among them, the adjustment of tools is time-consuming and laborious, not easy to be accurate, and finally requires trial cutting.

[0003] Traditional tool setting instruments mainly rely on operators to use calipers or visual inspection methods to confirm the clamping length of tools. However, these methods have the following disadvantages: 1. Slow efficiency, 2. Poor accuracy, 3. High professional quality requirements for operators. Therefore, there is a need for an automatic tool loading length device for a tool presetting instrument now. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic tool loading length device for a tool presetting instrument, to solve the problem that in the traditional tool presetting process, the clamping length of tools often depends on manual operation and visual judgment, resulting in large errors and uncertainties, so as to solve the technical problems mentioned in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an automatic tool loading length device for a tool presetting instrument, including a main base, a motor is installed on the front side of the main base, and a first synchronous pulley is key-connected to the output end of the motor;

[0006] A second synchronous pulley is rotatably installed inside the main base corresponding to the rear side of the first synchronous pulley. The first synchronous pulley and the second synchronous pulley are installed in a linkage manner through a belt. A positioning sleeve rod penetrates through the center of the second synchronous pulley. A push rod is arranged inside the positioning sleeve rod, and an adjusting bush is installed on the outer arc surface of the positioning sleeve rod;

[0007] A limiting plate is bolted and installed inside the main base above the second synchronous pulley, and a group of magnetic switches are installed on the upper and lower sides of the limiting plate respectively.

[0008] Preferably, the main base is composed of two groups of plates. A limiting groove is opened on the upper part of the front side of the main base. A motor base is installed inside the limiting groove. The motor is installed on the upper part of the motor base. The first synchronous pulley penetrates through the motor base and is connected to the output end of the motor.

[0009] Preferably, a positioning plate is bolted and installed at the rear side inside the main base, the second synchronous pulley is installed on the upper part of the positioning plate, the bottom end of the positioning sleeve rod penetrates through the positioning plate and is installed, and an anti-recoil nut is tightly installed on the surface of the positioning sleeve rod below the positioning plate.

[0010] Preferably, a limiting seat is installed at the center of the upper surface of the second synchronous pulley, the outer arc surface of the positioning sleeve rod is fitted and installed on the inner wall of the limiting seat, a through hole is centrally formed in the limiting plate, and the top end of the positioning sleeve rod extends out from inside the through hole.

[0011] Preferably, a set of L-shaped positioning plates are respectively bolted and installed on the corresponding sides of the two plates, the two L-shaped positioning plates are respectively located on one side of the limiting plate, the two magnetic switches are respectively bolted inside a set of L-shaped positioning plates, and a control elastic piece is installed at the output end of the magnetic switch.

[0012] Preferably, a set of side grooves are respectively formed on the outer arc surface of the positioning sleeve rod at the positions corresponding to the two L-shaped positioning plates, and the control elastic piece is elastically clamped inside the side grooves.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] This device integrates an efficient and precise automatic tool loading system, and its core components work together to achieve rapid and accurate installation of tools. The main base, as a stable support for the entire system, is specially designed with an automatic tool loading length adjustment function to adapt to the tool requirements of different specifications. The motor base is specifically used for installing the driving motor and is equipped with a device for adjusting the tightness of the belt to ensure stable and efficient power transmission;

[0015] Under the precise command of the control system, the driving motor drives the synchronous pulley installed on the motor driving rod to rotate through forward and reverse rotation control. This rotational movement is transmitted to the synchronous pulley on the adjusting bushing through the belt, achieving synchronous movement between the two. Therefore, the adjusting bushing can perform precise up and down movement under the drive of the motor. This movement process is precisely monitored by the 8# magnetic switch to ensure that the bushing reaches the predetermined position.

[0016] The ejector rod located inside the adjusting bushing directly contacts the tool to be installed, and the precise axial movement of the ejector rod is driven by the movement of the bushing, thereby completing the installation or adjustment of the tool. In order to prevent unnecessary recoil between the adjusting bushing and the fixed nut during the movement process. BRIEF DESCRIPTION OF THE DRAWINGS
