The center force measuring device comprises a center (3) and a lathe tail base (10); a center sleeve (9) is mounted on the lathe tail base (10); the back end of the center (3) is connected with a pressure sensor (6), and is mounted in a sliding groove at the center of the center sleeve (9); and the pressure sensor (6) is connected with an electric control instrument through a cable. The left end of the center sleeve (9) is mounted on a center baffle (2). According to the center force measuring device provided by the utility model, an axial force supplied to a workpiece by the center (3) is transmitted to the pressure sensor (6), so that the accurate pressure value can be displayed in an electrically controlled manner. Therefore, the axial pressure stressed by the workpiece in a machining process can be severely controlled.

Description

A force measuring device for the top end of a machine tool tailstock

technical field

The utility model relates to a force measuring device used on a machine tool. the

Background technique

At present, when processing slender parts, such as a shaft, one end is installed on the chuck, and the other end is placed on the top of the tailstock of the machine tool, and the axial pressure is applied to the part through the chuck and the top. Therefore, the workpiece is fixed in the axial direction and can only rotate around the axis. The current problem is that the axial pressure applied to the workpiece cannot be accurately controlled, and it is judged by the experience of the workers. If the pressure is too small, the workpiece cannot be fixed, and if the pressure is too large, it will easily cause deformation of the part and the processing speed cannot be increased. As a result, the processing efficiency is too low when processing the same type of slender parts in batches, and the outer surface of the parts is easily damaged during processing, resulting in the scrapping of the parts. Moreover, when the axial pressure is too large or too small, the roundness and roughness of the workpiece cannot be guaranteed, which seriously affects the quality of the workpiece and brings certain difficulties to the processing of slender parts. Therefore, there is a need for a device that can accurately control the axial pressure. the

Contents of the invention

The technical problem to be solved by the utility model: Aiming at the problem that the axial pressure used to clamp the workpiece cannot be accurately controlled during the machining process of the machine tool, a device that can accurately detect the axial pressure is provided. the

The technical scheme of the utility model:

A machine tool tailstock tip force measuring device, including the tip and the machine tool tailstock, the tip sleeve is installed on the machine tool tailstock, the rear end of the tip is connected to the pressure sensor, installed in the chute in the center of the tip sleeve, and the pressure sensor passes through the cable and the electric Control instrumentation connection.

A top baffle is installed on the left end of the top sleeve. the

The rear end of the tip is connected to the spring, and the other end of the spring is connected to the left baffle set at the left end of the pressure sensor. the

The right end of the pressure sensor is connected with the right baffle, and a top core is arranged between the right baffle and the tailstock of the machine tool. the

The beneficial effects of the utility model:

1. The utility model uses a pressure sensor to measure the axial pressure, which is displayed by the electrical control instrument, and can accurately measure the axial force of the workpiece, and accumulate theoretical basis for processing different types of slender shaft parts, and can also use this Find the most suitable axial pressure, and use the most suitable axial pressure to clamp the workpiece in subsequent processing.

2. The degree of freedom of the tip is limited by the chute in the tip sleeve, which can effectively maintain the concentricity between the tip and the spindle, reduce the error range, and effectively improve the machining accuracy and efficiency of slender parts. the

3. The method is simple and easy to implement. The device adopted is compact in structure, reasonable in layout, convenient in operation, economical and practical, and is especially suitable for mass processing of the same type of slender shaft parts. the

Detailed ways:

Embodiment: As shown in Figure 1, there is a circular bump on the left end of the machine tool tailstock 10. The right end of the center sleeve 9 is placed on this bump and connected to the machine tool tailstock 10 by screws. The interior of the center sleeve 9 is set in turn from the right There are top core 8, right block 7, pressure sensor 6, left block 5, spring 4 and tip 3, left baffle 5 and pressure sensor 6, pressure sensor 6 and right baffle 7, right baffle 7 and top core 8 are all connected by screws, and the top core 8 is placed on the tailstock 10 of the machine tool; the inside of the left section of the top sleeve 9 is a chute, and the top 3 is installed in the chute, and the diameter of the chute is the same as that of the top 3. The top stopper 2 is installed on the left end of the cover 9 to prevent the top 3 from coming out. Pressure sensor 6 is connected with electric control instrument by cable.

Principle: The axial force applied by the top 3 to the workpiece 1 is transmitted to the pressure sensor 6 through the contraction of the spring 4, so that the precise pressure value is displayed through electrical control, so that the axial force of the workpiece 1 during processing can be strictly controlled. pressure. the
